      Flow chart describing the Registrant's general research, development
      and business strategy. The flow chart contains the individual steps
      of the Registrant's overall strategy beginning with the Registrant's
      formulation of database information, subsequent gene and genealogy
      research, discovery of gene mutations and development of therapeutic
      and diagnostic products.

  This graphical depiction of the Company's strategy highlights Myriad's
proprietary gene discovery technologies and product opportunities. Myriad
leverages its proprietary database of families to link important disease-
predisposing genes to specific chromosomes. The Company employs its proprietary
high-speed sequencing technologies to discover disease-predisposing genes. The
Company can then pursue important commercial opportunities including
development of genetic testing products such as BRACAnalysis(TM), the first
comprehensive sequence-based genetic test, and gene therapy and protein
replacement therapy products. Understanding the biochemical pathway and protein
function can then lead to novel therapeutic targets that the Company may use to
develop new therapies in conjunction with its corporate partners and
independently.

  The following summary is qualified in its entirety by the more detailed
information and the financial statements and notes thereto appearing elsewhere
or incorporated by reference in this Prospectus. Except where otherwise noted,
all information in this Prospectus assumes no exercise of the Underwriters'
over-allotment option. See "Underwriting."
 
                                  THE COMPANY
 
  Myriad Genetics, Inc. is a leader in the discovery and sequencing of genes
related to major common diseases, such as cancer and cardiovascular disease.
The Company utilizes analyses of extensive family histories and genetic
material, as well as a number of proprietary technologies, to identify
inherited mutations which increase the risk to individuals of developing these
diseases. The Company has also developed a proprietary high-throughput assay to
identify protein-protein interactions. The Company believes that the
application of these technologies may provide new insights into protein
function and cellular organization which may lead to the identification of
novel therapeutic targets. The discovery of disease-predisposing genes and
their biochemical pathways provides the Company with two significant commercial
opportunities: (i) the development and marketing of genetic testing and
information services, such as its recently launched BRACAnalysis(TM) test, for
the identification of individuals who are genetically predisposed to developing
a particular disease, and (ii) the development of therapeutic products for the
treatment and prevention of major diseases associated with these genes and
their biochemical pathways. The Company intends to pursue the development of
therapeutic products either in conjunction with its strategic partners such as
Ciba-Geigy Corporation ("Ciba"), Bayer Corporation ("Bayer") and Eli Lilly and
Company ("Lilly"), or independently.
 
  Myriad has achieved the following major milestones:
 
  . Discovered, with its academic collaborators, the complete sequence of the
     BRCA1 and BRCA2 breast and ovarian cancer predisposing genes. These two
     genes are responsible for the majority of early onset hereditary breast
     and ovarian cancers;
 
  . Launched its first commercial genetic predisposition test,
     BRACAnalysis(TM), a comprehensive BRCA1 and BRCA2 sequence analysis for
     susceptibility to breast and ovarian cancer;
 
  . Identified nine new genes that interact in the BRCA1 biochemical pathway
     and two new genes that interact in the BRCA2 biochemical pathway;
 
  . Discovered the tumor suppressor function of the cell cycle gene MTS1, which
     is responsible for the majority of hereditary melanoma, and discovered and
     sequenced two other cell cycle genes, MTS2 and MTS3, and is analyzing
     their potential role in cancer;
 
  . Discovered, with its academic collaborators, the chromosomal location of
     nine additional major genes, including genes involved in heart disease,
     cancer, osteoporosis and obesity;
 
  . Conducted approximately 2,000 DNA analyses in conjunction with an ongoing
     study by the National Institutes of Health to determine whether or not the
     Company's patented AGT gene mutations can be used to predict salt-
     dependent hypertension; and
 
  . Established strategic alliances with Bayer, Ciba and Lilly for the
     discovery of genes related to respiratory diseases and metabolic
     disorders, cardiovascular diseases and breast cancer, respectively.
     Under these agreements, the Company may receive up to an aggregate of $135
     million in equity investments, research funding and milestone payments, as
     well as royalties on the sale of future therapeutic products. To date, the
     Company has received $32 million under the agreements.

  The Company has begun commercialization of its gene discoveries by providing
genetic tests for individuals to determine whether they have inherited gene
mutations which may increase their risk for specific diseases. On October 30,
1996, Myriad introduced BRACAnalysis(TM), an important genetic test for women
who have been diagnosed with breast or ovarian cancer and women who are at risk
for hereditary breast and ovarian cancer. The Company believes that
BRACAnalysis(TM) is the first comprehensive BRCA1 and BRCA2 sequence analysis
for susceptibility to breast and ovarian cancer. Women who may benefit from
BRACAnalysis(TM) include: women with a diagnosis of breast or ovarian cancer,
especially premenopausal breast cancer; women with a family history of breast
or ovarian cancer; and women with a blood relative who is known to have a
mutation in BRCA1 or BRCA2.
 
  Myriad has developed a highly automated genetic testing platform which the
Company believes will enable it, once it has discovered and sequenced a gene,
to develop a test for genetic predisposition relatively quickly and
economically. For example, the Company introduced BRACAnalysis(TM) in October
1996, less than one year after it discovered the full sequence of BRCA2. The
Company believes that the information gained from tests that confirm genetic
predisposition has potential value to individuals and their health care
providers in the following areas: (i) proactive health care and lifestyle
decisions that may delay or prevent the onset of disease; (ii) early detection
of disease; and (iii) selection of the most appropriate treatment. Through its
wholly-owned subsidiary, Myriad Genetic Laboratories, Inc. ("Myriad Labs"), the
Company has established a genetic predisposition testing laboratory which has
received federal certification under the Clinical Laboratory Improvements
Amendments Act of 1988 ("CLIA").
 
  In order to accelerate its gene discovery and therapeutic target
identification programs, the Company employs three synergistic sets of
technologies: (i) the genetic analysis of large Utah families performed by the
Company's scientists and collaborators; (ii) the Company's proprietary
bioinformatic gene mapping, sequencing and cloning technologies; and (iii) the
Company's advanced protein interaction and functional genomics technologies.
The Company's collaborators at the University of Utah and IHC Health Services,
Inc. ("IHC") have extensively studied large, multi-generational Utah families
with histories of high rates of certain diseases, including cancer and
cardiovascular disease. The clinical information from these studies, together
with genetic analysis of the more than 35,000 DNA samples collected from family
members, provides the Company with an unparalleled opportunity for accelerating
several critical steps of the gene discovery process. The Company uses
proprietary mapping and DNA sequencing technologies to identify a narrow
chromosomal region, to isolate candidate gene sequences and, ultimately, to
identify the actual DNA sequence comprising the disease-predisposing gene. Once
an important disease-predisposing gene has been identified, the Company uses
advanced protein interaction technologies to identify genes that are upstream
and downstream in the biochemical pathways from the gene discovered in order to
understand the biochemical pathways involved in the disease process. This
enables Myriad and its corporate partners to select promising points of
therapeutic intervention along the biochemical pathway.
 
  Myriad's business strategy has five primary components: (i) to expand the
Company's leadership position in discovering and sequencing genes; (ii) to
build the Company's genetic testing and information services business; (iii)
based on its gene discoveries, to identify potential therapeutic targets by
understanding the biochemical pathways related to common diseases; (iv) to
capitalize on strategic alliances with corporate partners to obtain financing
for a major portion of the Company's research and to commercialize certain
therapeutic products for the treatment and prevention of disease; and (v)
longer term, to pursue the independent marketing and development of therapeutic
products based on certain gene discoveries.
 
  The Company's executive offices are located at 320 Wakara Way, Salt Lake
City, Utah 84108, and its telephone number is (801) 584-3600.

EARLY STAGE OF DEVELOPMENT; HISTORY OF OPERATING LOSSES; ANTICIPATION OF
FUTURE LOSSES AND QUARTERLY FLUCTUATIONS
 
  The Company was formed in 1991 and has been engaged primarily in research
directed toward the discovery and sequencing of genes that predispose
individuals to common diseases and the development of a genetic predisposition
test. The Company announced in October 1996 the commercial introduction of
BRACAnalysis(TM), its first genetic predisposition test. No significant
revenues from BRACAnalysis(TM) have been generated to date. Significant
additional expenditures will be required to market the BRACAnalysis(TM) test,
and significant additional research and development will be required to fund
the Company's ongoing gene discovery programs and commercialize other gene
discoveries. As of September 30, 1996, the Company had an accumulated deficit
of approximately $17.8 million. There can be no assurance that the Company
will succeed in successfully commercializing BRACAnalysis(TM). Given the
uncertainties surrounding the commercialization of BRACAnalysis(TM) and other
genetic predisposition tests, the Company is unable to predict when it will
achieve profitability, if ever. Quarterly fluctuations in operating results,
announcements by the Company, its collaborative partners or the Company's
present or potential competitors, technological innovations or new commercial
products or services, announcements by the Company of regulatory developments,
developments or disputes concerning patent or proprietary rights or public
concern regarding the safety, efficacy or other implications of the products
or services developed or to be developed by the Company or its collaborators
and other events or factors may have a significant impact on the Company's
business, financial condition and results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."
 
UNCERTAINTY OF MARKET ACCEPTANCE FOR BRACANALYSIS(TM) AND OTHER GENETIC TESTS
 
  The commercial success of BRACAnalysis(TM) and other genetic predisposition
tests which the Company may develop will depend upon their acceptance as
medically useful and cost-effective by physicians and other members of the
medical community, patients and third-party payors. Broad market acceptance
can be achieved only with substantial education about the benefits and
limitations of such tests, as well as resolution of concerns about their
appropriate and ethical use. For example, there continues to be widespread
concern that people with genetic predispositions to diseases may suffer
discrimination from employers, as well as providers of health and life
insurance. There are also certain groups who oppose the use of genetic tests
for inherited diseases for which no cures currently exist. The Company will be
required to expend substantial financial resources to responsibly promote the
benefits of its BRACAnalysis(TM) test and any future predisposition tests it
may develop, including educating medical caregivers, policymakers, patients,
third-party payors and others. There can be no assurance that BRACAnalysis(TM)
or other genetic predisposition tests that may be developed by the Company
will gain market acceptance on a timely basis, if at all. Failure to achieve
market acceptance would have a material adverse effect on the Company's
business, financial condition and results of operations. See "--Uncertain
Availability of Health Care Reimbursement," "Business--Myriad's Gene Discovery
Programs," "--Product Development Programs" and "--Myriad's Commercialization
Strategy."
 
UNCERTAIN AVAILABILITY OF HEALTH CARE REIMBURSEMENT
 
  The Company's ability to successfully commercialize the BRACAnalysis(TM)
test and other genetic predisposition tests that it may develop, and the
ability of its collaborative partners to successfully commercialize
therapeutic products, depends in part on obtaining adequate reimbursement for
such services and products and related treatments from government and private
health care insurers (including health maintenance organizations) and other
third-party payors. Physicians' decisions to recommend BRACAnalysis(TM) and
other genetic
 
                                       6
<PAGE>
 
predisposition tests, as well as patients' elections to pursue testing, are
likely to be heavily influenced by the scope and extent of coverage for such
tests by third-party payors. Government and private third-party payors are
increasingly attempting to contain health care costs by limiting both the
extent of coverage and the reimbursement rate for new diagnostic and
therapeutic products and services. In particular, services which are determined
to be investigational in nature or which are not considered "reasonable and
necessary" for diagnosis or treatment may be denied reimbursement coverage. To
date, few third-party payors have taken a position on their willingness to
reimburse patients for BRACAnalysis(TM). As a result, initially the Company
expects to offer the BRACAnalysis(TM) test to patients on a direct payment
basis. The Company has established a list price of $2,400 for full sequence
tests and $395 for single amplicon tests for family members of individuals who
have been identified by the Company as carrying specific mutations. The Company
has established the pricing structure based on the complexity, sophistication
and potential usefulness of the test information to patients and their
physicians. There can be no assurance that third-party payors will elect to
provide full reimbursement coverage for the BRACAnalysis(TM) test, if at all.
If adequate reimbursement coverage is not available from third-party payors,
there can be no assurance that individuals will elect to pay directly for the
test and market acceptance of the test will likely be adversely impacted, which
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
  In addition, Medicare often permits coverage decisions to be made by its
carriers and intermediaries, leading to different coverage decisions in various
parts of the United States. Disapproval of, or limitations in, coverage by the
United States Health Care Financing Administration ("HCFA") or other third-
party payors, as well as inadequate payment levels, could have a material
adverse effect on the Company's future revenues. A key component in the
reimbursement decision by HCFA and most private insurers is the development of
Current Procedural Terminology ("CPT") codes, which are used in the submission
of claims to insurers for reimbursement for medical services. CPT codes are
developed, maintained and revised by a committee of medical specialists which
is administered by the American Medical Association ("AMA"). Currently,
reimbursement for genetic tests is made on the basis of CPT codes which may not
accurately reflect the complexity or sophistication of specific genetic tests.
The Company has petitioned the CPT committee for test specific codes which
better reflect the complexity, sophistication and resource utilization of the
Company's planned genetic tests. Additionally, new CPT codes for genetic
testing and sequencing, scheduled for implementation in 1998, are currently
under review by the AMA. There can be no assurance that the Company will
succeed in securing recognition by the CPT committee of specific codes for its
products and services. Failure to secure recognition or any delay in receiving
recognition by the CPT committee would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
LIMITED GENETIC TESTING AND INFORMATION SERVICES AND REGULATORY EXPERIENCE;
LIMITED MARKETING OR SALES EXPERIENCE
 
  The Company's business strategy is to commercialize its gene discoveries by
offering genetic information and testing services through its genetic testing
laboratory. The recent introduction of the BRACAnalysis(TM) test represents the
Company's first such effort. In preparation for the launch of BRACAnalysis(TM),
the Company has devoted substantial human and financial resources to the
establishment and staffing of a genetic testing laboratory and the building of
a sales and marketing infrastructure. However, the Company has limited
experience in operating a genetic testing laboratory and in commercially
marketing its services. There can be no assurance that the Company's genetic
testing laboratory will achieve efficient and effective operations. In
addition, there can be no assurance that the Company will succeed in marketing
the BRACAnalysis(TM) test or any other genetic predisposition tests it may
develop. Failure to successfully market such tests would have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Competition" and "Government Regulation."
 
DIFFICULTY OF DEVELOPING GENETIC TESTS; UNCERTAIN INTERPRETATION OF GENETIC
TEST RESULTS
 
  Whether the Company will be successful in offering genetic information and
testing services through its genetic testing laboratory depends in large part
upon the Company's ability to develop genetic tests for genes
 
                                       7
<PAGE>
 
discovered by the Company and its collaborators. Genetic tests that can
identify the existence of particular disease-predisposing gene mutations cannot
be developed until the relevant genes have been discovered and fully sequenced.
Genes such as the BRCA1 and BRCA2 breast and ovarian cancer genes, which form
the basis for the BRACAnalysis(TM) test, are complex and may have numerous
mutations (over 200 mutations of the BRCA1 and BRCA2 genes have been identified
to date). Moreover, a defective gene may malfunction in many different ways,
and the many mutated versions of the gene may make a genetic test difficult to
perform and interpret. Until a mutation has been characterized, researchers
cannot say for sure what risk it poses for an individual. Further, even when a
genetic test identifies the existence of a mutation in a particular individual,
the interpretation of the genetic test results is limited to the identification
of a statistical probability that the tested individual will develop the
disease for which the test has been completed. There can be no assurance that
the Company will be successful in developing additional genetic tests based on
the gene discoveries made by the Company and its collaborators or that the
BRACAnalysis(TM) test or other such tests will be able to be marketed at
acceptable prices or will receive commercial acceptance in the markets that the
Company expects to target.
 
RELIANCE ON COLLABORATIVE PARTNERS
 
  The Company's current strategy is to rely in the near term on collaborative
arrangements such as its collaborative arrangements with Ciba-Geigy Corporation
("Ciba"), Bayer Corporation ("Bayer") and Eli Lilly and Company ("Lilly") to
develop and commercialize therapeutic products based on its gene discoveries.
There can be no assurance that the Company will be able to negotiate additional
acceptable collaborative arrangements in the future, or that any collaborative
arrangement will be successful. In addition, there can be no assurance that the
Company's collaborative partners will not pursue alternative technologies or
develop alternative products either on their own or in collaboration with
others, including the Company's competitors, as a means of developing
diagnostic products or treatments for the diseases targeted by the
collaborative programs. The Company's receipt of a substantial portion of the
potential milestone payments under its collaborative agreements is dependent
upon the efforts of its strategic collaborators. Failure of any collaborative
arrangement could have a material adverse effect on the Company's business,
financial condition or results of operations. In addition, Ciba has the right
to terminate its research agreement after April 1997 if the Company fails to
achieve any research objective, and Bayer has the right to terminate its
research agreement after September 1997 if it is determined that the research
program is likely to fail to achieve its objectives in all areas and the
parties do not agree on alternative disease targets for the research program.
Termination by Ciba or Bayer of their respective agreements could have a
material adverse effect on the Company's business, financial condition or
results of operations. There can be no assurance that the interests of the
Company will continue to coincide with those of its collaborative partners, or
that some of its collaborative partners will not develop independently or with
third parties therapeutic or diagnostic products that could compete with those
developed in collaboration with its partners or independently. Additionally
there can be no assurance that disputes over rights or technology or other
proprietary interests will not arise. Such disputes or disagreements between
the Company and its collaborative partners could lead to delays in
collaborative research projects, or could result in litigation or arbitration,
any of which could have a material adverse effect on the Company's business,
financial condition or results of operations. In addition, there have been a
significant number of recent consolidations among pharmaceutical companies.
Such consolidations among the companies with which the Company is collaborating
could result in the diminution or termination of, or delays in, the development
or commercialization of the products or research programs under one or more of
the Company's collaborative agreements. For example, it has been announced that
Ciba plans to merge with Sandoz. In the event that, as a result of the merger
and ensuing transition, the priorities of Ciba are reassessed, Ciba may elect
to terminate or amend the terms of its collaboration with the Company, and the
Company's programs could be adversely affected. See "Business--Strategic
Alliances."
 
INTENSE SCIENTIFIC AND COMMERCIAL COMPETITION; TECHNOLOGICAL UNCERTAINTY
 
  Research in the field of disease-predisposing genes is intense and highly
competitive. Genetic research is characterized by rapid technological change.
Competitors of the Company in the United States and abroad are numerous and
include, among others, major pharmaceutical and diagnostic companies,
specialized biotechnology
 
                                       8
<PAGE>
 
firms, universities and other research institutions, including those receiving
funding from the Human Genome Project. Many of the Company's potential
competitors have considerably greater financial, technical, marketing and other
resources than the Company, which may allow these competitors to discover
important genes in advance of the Company. If the Company does not discover
disease-predisposing genes, characterize their function, develop genetic tests
and related information services based on such discoveries, obtain regulatory
and other approvals and launch such services or products before competitors,
the Company could be adversely affected. In addition, any predisposition tests
which the Company may develop, including the recently introduced
BRACAnalysis(TM) test, could be made obsolete by less expensive or more
effective tests or methods which may be developed in the future. The Company
expects competition to intensify in the fields in which it is involved as
technical advances in such fields are made and become more widely known.
 
  In addition, the Company is aware that other commercial testing laboratories
may seek to offer genetic predisposition tests based on gene discoveries made
by the Company and its collaborators. The Company is aware of several companies
and academic hospitals which already offer genetic predisposition tests based
on certain mutations of the BRCA1 and BRCA2 genes. Other companies, including
major genetic reference laboratories, may seek to offer their own genetic
predisposition tests for certain BRCA1 and BRCA2 mutations, depending on market
acceptance of the BRACAnalysis(TM) test. There can be no assurance that such
competition will not have a material adverse effect on the Company's
predisposition testing business or that the Company will be successful in
enforcing its proprietary position with respect to the BRCA1 and BRCA2 gene
discoveries.
 
  The Company also expects to encounter significant competition with respect to
any therapeutic products that it may develop or commercialize. Competition in
the field of therapeutic development is intense and is characterized by rapid
technological change. Competitors of the Company are numerous and include,
among others, major pharmaceutical companies and biotechnology firms, many of
which have substantially greater financial, technical, marketing and other
resources than the Company. Those companies that complete clinical trials,
obtain required regulatory approvals and commence commercial sales of
therapeutic products prior to the Company may achieve a significant competitive
advantage in marketing and commercializing their products. There can be no
assurance that the Company or its collaborative partners will be able to
develop therapeutic products successfully or will obtain patents covering such
products that provide protection against its competitors. Moreover, there can
be no assurance that the Company's competitors will not succeed in developing
therapeutic products that circumvent the Company's technologies or products or
that such competitors will not succeed in developing technologies or products
that are more effective than those developed by the Company and its
collaborative partners or that would render technology or products of the
Company and its collaborators less competitive or obsolete. See "Business--
Competition" and "--Patents and Proprietary Rights."
 
NEED FOR FUTURE CAPITAL; UNCERTAINTY OF ADDITIONAL FUNDING
 
  In pursuing the commercial introduction of BRACAnalysis(TM), the Company has
incurred and will continue to incur significant costs to market
BRACAnalysis(TM) and to educate physicians, health care providers and genetic
counselors. In addition, the Company's ongoing gene discovery programs, genetic
test development and possible future programs to independently develop
therapeutics based on gene discoveries will require substantial additional cash
resources. The Company has funded its operations to date primarily through
equity financings and corporate collaborations. In order to grow and expand its
business, the Company will need to raise additional funds. The Company's future
capital requirements will depend on many factors, including, but not limited
to, continued scientific progress in its research and development programs, the
costs and timing of patent prosecutions, competing technological and market
developments, the cost and timing of regulatory approvals, possible changes in
existing collaborative relationships, the ability of the Company to establish
additional collaborative relationships and effective commercialization
activities and facilities expansions as required. Because of the Company's
potential long-term capital requirements, it may access the public or private
equity markets whenever conditions are favorable, even if it does not have an
immediate need for additional capital at that time. If additional funds are
raised by issuing equity securities, existing shareholders may suffer
significant dilution. There can be no assurance that any such additional
funding will be available to the Company or, if available, that it will be on
reasonable terms. If adequate funds are not available, the Company may be
required
 
                                       9
<PAGE>
 
to scale down research and development programs, curtail capital expenditures
and reduce marketing and other operating expenses. Some of the Company's
currently targeted gene discovery research programs will be dependent on
funding from collaborative partners. If the Company is not successful in
finding, entering into and maintaining arrangements with collaborative
partners, its development efforts could be delayed, scaled down or curtailed.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations--Liquidity and Capital Resources."
 
NO ASSURANCE OF FUTURE GOVERNMENTAL APPROVAL; GOVERNMENT REGULATION
 
  The establishment and operation of the Company's genetic testing laboratory
and production and marketing of services and products developed through its
technologies, as well as its ongoing research and development activities, are
subject to regulation by numerous federal, state and local governmental
authorities in the United States and by comparable regulatory agencies in
other countries where the Company or any collaborative partner might seek to
establish a genetic testing laboratory and market services and products that
may be developed. On the state level, only New York has implemented
regulations concerning DNA-based diagnostic testing and the Company has
received approval from the State of New York for both BRCA1 and BRCA2 genetic
testing. The Company is aware of several other states that require licensing
or registration of clinical laboratory activities. The Company believes that
it has taken all steps required of it in such jurisdictions in order for
Myriad Labs to conduct business in those jurisdictions. However, there can be
no assurance that the Company will be able to maintain state level regulatory
compliance in all states where Myriad Labs may do business. Failure to
maintain state regulatory compliance, or changes in state regulatory schemes,
could result in a substantial curtailment or even prohibition of Myriad Lab's
clinical activities and could have a material adverse effect on the Company's
business, financial condition and results of operations. The Company has
received federal certification to operate its genetic testing laboratory from
the Department of Health and Human Services. However, no assurance can be
given that the Company's certification will not subsequently be revoked,
suspended, or limited or that the certification will be renewed on a yearly
basis as required. Furthermore, while the United States Food and Drug
Administration ("FDA") does not currently regulate genetic tests developed by
the Company if used in the Company's own testing laboratory, the FDA has
stated that it has the right to do so, and there can be no assurance that the
FDA will not seek to regulate such tests in the future. If the FDA should
require that these tests receive FDA approval prior to their use in the
Company's genetic testing laboratory, there can be no assurance such approval
would be received on a timely basis, if at all.
 
  Further, the FDA has proposed that it regulate as medical devices the
"active ingredients" (known as "analyte specific reagents" or "ASRs") of
certain tests developed in-house by clinical laboratories. In the event that
the FDA requires approval of ASRs used in the BRACAnalysis(TM) test or any
other test developed by the Company, there can be no assurance such approval
would be received on a timely basis, if at all. The failure to receive such
approval could require the Company to develop alternative testing methods or
utilize approved ASRs, which could result in the delay or cessation of such
tests. Such a delay or cessation would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
  In addition, prior to marketing in the United States any diagnostic product
for use by others (including any test to be performed by others which when
performed by the Company does not require approval) or any therapeutic product
developed by the Company or its collaborative partners, such product would be
required to undergo an extensive regulatory approval process by the FDA,
including clinical trials. The regulatory process, which includes preclinical
testing and clinical trials of each therapeutic product in order to establish
its safety and efficacy, can take many years and requires the expenditure of
substantial resources. Data obtained from preclinical and clinical activities
are susceptible to varying interpretations which could delay, limit or prevent
regulatory agency approval. In addition, delays or rejections may be
encountered during the period of therapeutic development, including delays
during the period of review of any application. Delays in obtaining regulatory
approvals could adversely affect the marketing of any therapeutics developed
by the Company or its collaborative partners, impose costly procedures upon
the Company's and its collaborative partners' activities, diminish any
competitive advantages that the Company or its collaborative partners may
attain and adversely affect the Company's ability to receive royalties. There
can be no assurance that regulatory approvals will be obtained for any
products developed by the Company or its collaborative partners. Moreover, if
regulatory approval of a
 
                                      10
<PAGE>
 
product is granted, such approval may impose limitations on the indicated uses
for which it may be marketed. Further, even if such regulatory approval is
obtained, a marketed product and its manufacturer are subject to continuing
review, and discovery of previously unknown problems with a product or
manufacturer may result in restrictions on such product or manufacturer,
including withdrawal of the product from the market. In addition, certain
states require the licensing of genetic testing labs or the services they
provide. No assurance can be given that any applicable federal, state or local
licensure requirements will be met, that any such regulations will not be
modified or that the Company will be able to comply with any new or modified
regulation. Failure to comply with any material governmental regulation could
have a material adverse effect on the Company's business, financial condition
or results of operations. See "Business--Government Regulation."
 
ETHICAL, LEGAL AND SOCIAL IMPLICATIONS OF GENETIC PREDISPOSITION TESTING
 
  The prospect of broadly available genetic predisposition testing has raised
issues which are currently being widely discussed by the medical and
scientific communities, as well as other interested groups and organizations,
regarding the appropriate utilization and the confidentiality of information
provided by such testing. It is possible that discrimination by insurance
companies could occur through the raising of premiums by insurers to
prohibitive levels, outright cancellation of insurance or unwillingness to
provide coverage to patients shown to have a genetic predisposition to a
particular disease. The Company could experience a delay in market penetration
or a reduction in the size of its potential serviceable market, adversely
affecting future revenue, if insurance discrimination were to become a
significant barrier to testing acceptance. Similarly, employers could
discriminate against employees with a positive genetic predisposition due to
the increased risk for disease resulting in possible cost increases for health
insurance and the potential for lost employment time. Finally, governmental
authorities could, for social or other purposes, limit the use of genetic
testing or prohibit testing for genetic predisposition to certain conditions.
For these reasons, the Company could experience a delay or reduction in test
acceptance, which could materially adversely affect the Company's business,
financial condition or results of operations.
 
UNCERTAIN ABILITY TO PROTECT PROPRIETARY TECHNOLOGY
 
  The Company's success will depend, in part, on its ability to obtain patent
protection, both in the United States and in other countries, for genes it
discovers, mutations or products of the genes and related processes,
transgenic animals and other inventions which it believes are patentable, as
well as its ability to preserve its trade secrets and to operate without
infringing the proprietary rights of third parties. The patent position of
biotechnology firms generally is highly uncertain and involves complex legal
and factual questions. To date there has not emerged from the United States
Patent and Trademark Office ("PTO") or the courts a consistent policy
regarding the breadth of claims allowed in biotechnology patents, in
particular, with respect to the doctrine of equivalents and how it will be
applied to biotechnology claims. A case relating to the scope of the doctrine
of equivalents recently was argued before the Supreme Court, but a decision is
not expected for several months. There can be no assurance that the Company's
or its licensor's patent applications will ever issue as patents or that the
claims of any issued patents will afford meaningful protection for the
Company's technology or products. In addition, there can be no assurance that
any patents issued to the Company or its licensors will not be challenged, and
subsequently narrowed, invalidated or circumvented.
 
  The Company's products may also conflict with patents which have been or may
be granted to others. As the biotechnology industry expands and more patents
are filed and issued, the risk increases that the Company's products may give
rise to a declaration of interference by the PTO, or to claims of patent
infringement by other companies, institutions or individuals. Such entities or
persons could bring legal proceedings against the Company seeking damages or
seeking to enjoin the Company from testing, manufacturing or marketing its
products. Patent litigation is costly, and even if the Company prevails, the
cost of such litigation could have an adverse effect on the Company. If the
other parties in any such actions are successful, in addition to any liability
for damages, the Company could be required to cease the infringing activity or
obtain a license. There can be no assurance that any license required would be
available to the Company on acceptable terms, if at all. Failure by the
Company to obtain a license to any technology that it may require to
commercialize its products could have a material adverse effect on the
Company's business, financial condition and results of operations. In
addition,
 
                                      11

there is considerable pressure on academic institutions to publish discoveries
in the genetic field. Such a publication by an academic collaborator of the
Company, prior to the filing of a patent application on such discovery, may
compromise the ability of the Company to obtain U.S. and foreign patent
protection for the discovery.
 
  The Company is aware that another group has filed patent applications having
claims to the p16 and p15 proteins and their coding sequences and to the
detection for the risk of cancer by analyzing these coding sequences. The
Company has discovered that the gene for p16 is the MTS1 gene which suppresses
tumor growth in many types of cancer. Should such other group obtain patent
protection with respect to its discoveries, the Company's commercialization of
services and products based on MTS1 or MTS2 could be limited or prohibited.
Additionally, sometimes in similar situations the PTO may declare an
interference between competing patent applications. If an interference is
declared, there can be no assurance that the Company would prevail in the
interference. If such other party prevails in the interference, the Company
may be precluded from commercializing services or products based on MTS1 or
MTS2, or may be required to seek a license. There can be no assurance that a
license would be available to the Company on commercially acceptable terms, if
at all.
 
  The Company believes that another group may have filed competing claims for
a portion of the BRCA2 protein and its coding sequence. The Company has
discovered the complete BRCA2 protein and its coding sequence. Should such
other group obtain patent protection with respect to its discoveries or
prevail in any interference, the Company's commercialization of services or
products based on BRCA2 could be limited or prohibited.
 
  The Company also relies upon unpatented proprietary technologies. There can
be no assurance that the Company can adequately protect its rights in such
unpatented proprietary technologies, that others will not independently
develop substantially equivalent proprietary information or techniques, or
otherwise gain access to the Company's proprietary technologies or disclose
such technologies. See "Business--Patents and Proprietary Rights."
 
DEPENDENCE ON RESEARCH COLLABORATORS, SCIENTIFIC ADVISORS AND LICENSED
TECHNOLOGY
 
  The Company has relationships with collaborators at academic and other
institutions who conduct research at the Company's request. Such collaborators
are not employees of the Company. As a result, the Company has limited control
over their activities and, except as otherwise required by its collaboration
agreements, can expect only limited amounts of their time to be dedicated to
the Company's activities. The Company's collaborations with the University of
Utah are based on information derived from the collaborators' databases of
large Utah families, DNA samples and clinical and family history information
collected on these family members. Similarly, the Company has established
collaborations with the University of Texas M.D. Anderson Cancer Center to
discover and sequence the gene for hereditary leukemia and with Intermountain
Health Care to pursue the discovery of genes involved in obesity,
osteoporosis, asthma, and certain central nervous system disorders. The
Company's ability to discover genes involved in human disease and
commercialize genetic testing and information services based on those genes
will depend in part on the continuation of such collaborations. There can be
no assurance that the Company will be able to negotiate additional acceptable
collaborations or that its existing collaborations will be successful.
 
  The Company's research collaborators and scientific advisors may have
relationships with other commercial entities, some of which could compete with
the Company. The research collaborators and scientific advisors sign
agreements which provide for confidentiality of the Company's proprietary
information and results of studies. There can be no assurance, however, that
the Company will be able to maintain the confidentiality of its technology and
other confidential information in connection with every collaboration, and
dissemination of the Company's information could have an adverse effect on the
Company's business.
 
  The Company is party to various license agreements under which it has rights
to use certain technologies owned by other companies in its proprietary
research, development and testing processes. One such agreement,
 
                                      12
<PAGE>
 
with Roche Molecular Systems, Inc., is of material importance to the Company.
There can be no assurance that the Company will be able to continue to license
such technologies or find suitable alternatives to such technologies on timely
or commercially reasonable terms, if at all. The loss of the right to use such
licensed technologies would have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--
Academic Collaborations."
 
DEPENDENCE ON KEY PERSONNEL AND CONSULTANTS; NO POST-EMPLOYMENT NON-
COMPETITION AGREEMENTS
 
  Because of the specialized scientific nature of the Company's business, the
Company is highly dependent upon its ability to attract and retain qualified
management, scientific and technical personnel. The Company is currently
recruiting additional qualified management, scientific and technical
personnel. Competition for such personnel is intense. Loss of the services of
or failure to recruit additional key management, scientific and technical
personnel would adversely affect the Company's research and development
programs and genetic testing and information business and would impede the
achievement of its business objectives.
 
  The Company's agreements with its employees generally provide for employment
that can be terminated by either party without cause at any time, subject to
certain notice requirements. Further, the non-competition provision to which
each employee is subject expires on the applicable date of termination of
employment.
 
DEPENDENCE ON THIRD PARTIES FOR SUPPLIES
 
  The Company currently uses a single supplier to provide its gene sequencing
machines and certain reagents required in connection with the gene discovery
process. The Company does not believe that there are other gene sequencing
machines currently available which are as efficient as the machines used by
the Company. The Company believes that currently there are no alternative
suppliers of a few selected reagents. No assurance can be given that either
the gene sequencing machine or the reagents will remain available in
commercial quantities at acceptable costs. Should the Company be unable to
obtain additional gene sequencing machines or an adequate supply of reagents
or other ingredients at commercially reasonable rates, its ability to continue
to identify genes and perform genetic testing would be adversely affected.
 
PRODUCT AND PROFESSIONAL LIABILITY INSURANCE
 
  The Company's business, including its October 1996 introduction of the
BRACAnalysis(TM) genetic predisposition test for the BRCA1 and BRCA2 breast
and ovarian cancer genes, will expose it to potential liability risks inherent
in the testing, manufacturing and marketing of human diagnostic services and
therapeutic products. There can be no assurance that liability claims will not
be asserted against the Company. The Company has obtained product and
professional liability insurance in connection with beta testing of its
BRACAnalysis(TM) predisposition test and is currently pursuing expanded
coverage based on the commercial introduction of BRACAnalysis(TM). There can
be no assurance that the Company will be able to obtain or maintain such
insurance on acceptable terms, or that any insurance obtained will provide
adequate coverage against potential liabilities. There can be no assurance
that a liability claim, even one without merit, would not materially and
adversely affect the business or financial condition of the Company.
 
VOLATILITY OF SHARE PRICE
 
  The market prices for securities of biotechnology companies have been
volatile. The market price for the Company's Common Stock has fluctuated
significantly since public trading commenced in October 1995, and it is likely
that the market price will continue to fluctuate in the future. Quarterly
fluctuations in operating results, announcements by the Company, its
collaborative partners or the Company's present or potential competitors,
technological innovations or new commercial products or services,
announcements by the Company of regulatory developments, developments or
disputes concerning patent or proprietary rights or public concern regarding
the safety, efficacy or other implications of the products or services
developed or to be developed by the Company or its collaborators and other
events or factors may have a significant impact on the Company's business and
on the market price of the Common Stock. In addition, the stock market has
experienced extreme price and volume
 
                                      13
<PAGE>
 
fluctuations. This volatility has significantly affected the market prices for
securities of many biotechnology and pharmaceutical companies for reasons
frequently unrelated to the operating performance of the specific companies.
These broad market fluctuations may adversely affect the market price of the
Company's Common Stock. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
CONTROL BY EXISTING SHAREHOLDERS
 
  Following completion of this offering, directors, executive officers and
principal shareholders of the Company, and certain of their affiliates, will
beneficially own approximately 17.7% of the Company's outstanding Common Stock
(approximately 17.3% if the Underwriters' overallotment option is exercised in
full). Accordingly, these shareholders, individually and as a group, may be
able to influence the outcome of shareholder votes, including votes concerning
the election of directors, the adoption or amendment of provisions in the
Company's Restated Certificate of Incorporation or By-Laws and the approval of
certain mergers and other significant corporate transactions, including a sale
of substantially all of the Company's assets. Such control by existing
shareholders could have the effect of delaying, deferring or preventing a
change in control of the Company. See "Principal and Selling Stockholders."
 
EFFECT OF ANTI-TAKEOVER PROVISIONS
 
  The Company's Board of Directors are authorized to issue up to 5,000,000
shares of Preferred Stock and to determine the price, rights, preferences and
privileges of those shares without any further vote or action by the Company's
stockholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any shares of
Preferred Stock that may be issued in the future. While the Company has no
present intention to issue shares of Preferred Stock, such issuance, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult
for a third party to acquire a majority of the outstanding voting stock of the
Company. In addition, such Preferred Stock may have other rights, including
economic rights senior to the Common Stock, and, as a result, the issuance
thereof could have a material adverse effect on the market value of the Common
Stock. The Company's Restated Certificate of Incorporation provides for a
classified Board of Directors and members of the Board of Directors may be
removed only for cause upon the affirmative vote of holders of at least a
majority of the shares of capital stock of the Company entitled to vote.
Furthermore, the Company is subject to the anti-takeover provisions of Section
203 of the Delaware General Corporation Law, which prohibits the Company from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
first becomes an "interested stockholder," unless the business combination is
approved in a prescribed manner. The application of these provisions could
have the effect of delaying or preventing a change of control of the Company.
Certain other provisions of the Company's Restated Certificate of
Incorporation could also have the effect of delaying or preventing changes of
control or management of the Company, which could adversely affect the market
price of the Company's Common Stock.
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS; POSSIBLE ADVERSE EFFECT
ON FUTURE MARKET PRICE
 
  Future sales of Common Stock by existing stockholders could adversely affect
the prevailing market price for the Common Stock after the offering and the
Company's ability to raise additional capital. Upon consummation of this
offering, the Company will have 10,230,980 shares of Common Stock outstanding
(assuming no exercise of options or warrants to purchase Common Stock). Of
such shares, the 1,700,000 shares sold in this offering, together with
6,212,218 shares currently outstanding, generally will be freely tradeable
without restriction or further registration under the Securities Act of 1933,
as amended (the "Securities Act"). Of the remaining shares, 1,416,288 shares
held by "affiliates" of the Company may be publicly sold pursuant to the
conditions of Rule 144 under the Securities Act, and 902,474 shares will
become eligible for resale under Rule 144 commencing on various dates from
December 1996 through September 1997. The holders of 1,828,053 of such shares
have agreed not to sell or otherwise dispose of their shares for a period
ending 90 days after the date of this Prospectus (the "lock-up period"),
without the prior written consent of Cowen & Company. The Securities and
Exchange Commission has proposed an amendment to Rule 144 which would reduce
the holding period before shares subject to Rule 144 become eligible for sale
in the public market. This proposal, if adopted,
 
                                      14
<PAGE>
 
would substantially increase the number of shares of the Company's Common
Stock eligible for immediate sale following the expiration of the lock-up
period. No prediction can be made as to the effect, if any, that market sales
of such shares or the availability of such shares for future sale will have on
the market price of shares of Common Stock prevailing from time to time.
 
  The holders of 1,713,608 shares of Common Stock and shares of common stock
issuable upon exercise of warrants are entitled to certain registration rights
with respect to such shares. If such holders, by exercising their registration
rights, cause a large number of shares to be registered and sold in the public
market, such sales may have an adverse effect on the market price for the
Common Stock.
In addition, in a Company-initiated registration, if the Company is required
to include shares held by such holders pursuant to the exercise of their
"piggyback" registration rights, such sales may have an adverse effect on the
Company's ability to raise needed capital. See "Management," "Principal and
Selling Stockholders" and "Underwriting."
 
DILUTION; ABSENCE OF DIVIDENDS
 
  Purchasers in the offering will experience immediate and substantial
dilution in the net tangible book value of the Common Stock from the public
offering price. Additional dilution is likely to occur upon exercise of
options and warrants granted by the Company. See "Dilution." The Company has
never paid dividends and does not intend to pay any dividends in the
foreseeable future. See "Dividend Policy."
 
                                USE OF PROCEEDS
 
  The net proceeds to be received by the Company from the sale of the
1,500,000 shares of Common Stock offered hereby by the Company, at an assumed
offering price of $28.50 per share, and after deducting the underwriting
discount and estimated offering expenses payable by the Company are estimated
to be $39.6 million ($46.5 million if the Underwriters' over-allotment option
is exercised in full). The Company will not receive any of the proceeds from
the shares of Common Stock sold by the Selling Stockholders. See
"Underwriting."
 
  The Company intends to use the net proceeds of this offering to pursue the
commercial introduction of BRACAnalysis(TM), including costs associated with
the expansion of the sales force and related marketing expenses, and the
education of physicians, health care providers and genetic counselors; to fund
continued research and development activities to discover genes which
predispose individuals to common diseases, including ongoing development of
the Company's technology; to expand the Company's genetic testing business
through the launch of additional genetic testing programs; and to fund
research to elucidate the biochemical pathways and to identify interacting
proteins that could lead to potential therapeutic targets. The remainder of
such net proceeds will be used for working capital and general corporate
purposes. The Company may also use a portion of the net proceeds of the
offering to acquire businesses, technologies, or products complementary to the
Company's business, although the Company does not currently have any
commitments or agreements for, and is not involved in any negotiations for,
any such acquisition and there can be no assurance that any such acquisitions
will be made.
 
  The amount and timing of expenditures of working capital may vary
significantly depending upon numerous factors, including the progress of the
Company's research, gene discovery and development programs, the timing and
costs involved in obtaining regulatory approvals, the costs involved in
filing, prosecuting and enforcing patent claims, competing technological and
market developments, payments received under collaborative agreements, changes
in collaborative research relationships, the costs associated with potential
commercialization of its products, including the development of marketing and
sales capabilities, the cost and availability of third-party financing for
capital expenditures and administrative and legal expenses.
 
  The Company believes that its available cash and existing sources of
funding, together with the proceeds of this offering and interest earned
thereon, will be adequate to maintain its current and planned operations for
at least the next three years. See "Risk Factors--Need for Future Capital;
Uncertainty of Additional Funding."
 
  Until used, the Company intends to invest the net proceeds of this offering
in interest-bearing, investment-grade securities. While the net proceeds are
so invested, the interest earned by the Company on such proceeds will be
limited by available market rates. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations." The Company intends to
invest and use such proceeds so as not to be considered an "investment
company" under the Investment Company Act of 1940, as amended.

  The net tangible book value of the Common Stock at September 30, 1996 was
$67,577,153 or approximately $7.74 per share.
 
  After giving effect to the sale of 1,500,000 shares of Common Stock in this
offering at an assumed public offering price of $28.50 per share and the
receipt of the estimated net proceeds therefrom, the as adjusted net tangible
book value of the Company would have been $107,202,153 or $10.48 per share.
This represents an immediate increase in pro forma net tangible book value of
$2.74 per share to existing stockholders and immediate dilution in pro forma
net tangible book value of $18.02 per share to purchasers of Common Stock in
the offering, as illustrated in the following table:

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
Consolidated Financial Statements and related Notes contained elsewhere in
this Prospectus. This Prospectus contains forward-looking statements which
involve risks and uncertainties. The Company's actual results may differ
significantly from the results discussed in the forward-looking statements.
Factors that might cause such a difference include, but are not limited to,
those discussed in "Risk Factors."
 
OVERVIEW
 
  Since inception, the Company has devoted substantially all of its resources
to maintaining its research and development programs, establishing a genetic
testing laboratory, and supporting collaborative research agreements. To date,
the Company has not received any revenues from the sale of products. Revenues
received by the Company primarily have been payments pursuant to collaborative
research agreements. The Company has been unprofitable since its inception
and, for the quarter ended September 30, 1996, the Company had a net loss of
$2,830,079 and as of September 30, 1996 had an accumulated deficit of
$17,771,191.
 
  In August 1995, the Company completed a three-year collaborative research
and development agreement with Eli Lilly and Company ("Lilly") to locate and
sequence the BRCA1 breast and ovarian cancer gene. This agreement has provided
the Company with research funding and may in the future provide certain
additional payments upon the attainment of research and regulatory milestones
and royalty payments based on sales of any products resulting from the
collaboration. The Company did not recognize revenue from this agreement
during the quarter ended September 30, 1996.
 
  In April 1995, the Company commenced a five-year collaborative research and
development arrangement with Ciba-Geigy Corporation ("Ciba"). This
collaboration provides the Company with an equity investment, research funding
and potential milestone payments of up to $60,000,000. The Company is entitled
to receive royalties from sales of therapeutic products sold by Ciba. The
Company recognized $1,085,069 in revenue under this agreement for the quarter
ended September 30, 1996.
 
  In September 1995, the Company commenced a five-year collaborative research
and development arrangement with Bayer Corporation ("Bayer"). This
collaboration provides the Company with an equity investment, research funding
and potential milestone payments of up to $71,000,000. The Company is entitled
to receive royalties from sales of therapeutic products sold by Bayer. The
Company recognized $1,170,712 in revenue under this agreement for the quarter
ended September 30, 1996.
 
  The Company intends to enter into additional collaborative relationships to
locate and sequence genes associated with other common diseases as well as
continuing to fund internal research projects. There can be no assurance that
the Company will be able to enter into additional collaborative relationships
on terms acceptable to the Company. The Company expects to incur losses for at
least the next several years, primarily due to expansion of its research and
development programs, increasing staffing costs and expansion of its
facilities. Additionally, the Company expects to incur substantial sales,
marketing and other expenses in connection with launching its genetic
predisposition testing business. The Company expects that losses will
fluctuate from quarter to quarter and that such fluctuations may be
substantial.
 
  The Company devoted significant resources during the quarter to the beta
testing and validation of the Company's BRACAnalysis(TM) genetic
predisposition test for mutations of the BRCA1 and BRCA2 breast and ovarian
cancer genes, as well as building its sales and marketing force in preparation
for the commercial launch of the test. The Company commercially launched
BRACAnalysis(TM) on October 30, 1996. There can be no assurance that the
Company will succeed in achieving market acceptance for the BRACAnalysis(TM)
test.

RESULTS OF OPERATIONS
 
 Three months ended September 30, 1996 and 1995.
 
  Research revenues for the quarter ended September 30, 1996 increased
$1,182,881 from the same quarter of 1995. The increase was attributable to a
full quarter of both the Ciba and Bayer research collaboration agreements
providing ongoing research funding in 1996. For the first fiscal quarter in
1995, both research collaboration agreements were in their start-up phase.
Research revenue from the research collaboration agreements is recognized as
related costs are incurred.
 
  Research and development expenses for the quarter ended September 30, 1996
increased to $4,094,743 from $2,381,159 for the same quarter of 1995. This
increase was primarily due to an increase in third party research programs
funded by the Company, increased depreciation charges due to the purchase of
additional equipment, the hiring of additional personnel and the increased use
of laboratory supplies and reagents to meet the demands of the additional
research collaboration agreements. The Company also incurred increased
development expenses during the quarter related to the beta testing and
validation of the Company's BRACAnalysis(TM) genetic predisposition test for
mutations of the BRCA1 and BRCA2 breast and ovarian cancer genes. As
BRACAnalysis(TM) moves from the development stage to commercialization, the
Company expects research and development expenses to decrease as expenses
related to the test are classified as cost of sales. There can be no assurance
that the Company will be able to produce the test in a timely fashion or at
acceptable quality levels and prices.
 
  Selling, general and administrative expenses for the quarter ended September
30, 1996 increased $1,351,773 from the same quarter of 1995. The increase was
attributable to additional administrative, marketing and education personnel,
market research activities, education material development, facilities-related
costs and deferred compensation related to grants of stock options and
warrants. The Company expects its general and administrative expenses will
continue to increase in support of its research and development efforts and
genetic predisposition testing business.
 
  Interest income for the quarter ended September 30, 1996 increased to
$848,494 from $275,223 for the same quarter of 1995. This increase was
primarily due to the increased funds available for investment, which funds
were raised in the Company's initial public offering in October 1995, and in
connection with entering into the Company's research and development
collaborations with Ciba and Bayer in April 1995 and September 1995,
respectively. Interest expense for the quarter ended September 30, 1996,
amounting to $19,652, was due entirely to borrowings under the Company's
equipment financing facility, which are secured by equipment and have a
repayment term of 48 months from the date of funding. The net loss increased
to $2,830,079 for the quarter ended September 30, 1996 from $1,602,903 for the
same quarter in 1995.
 
 Years ended June 30, 1996 and 1995.
 
  Research revenues for the Company's fiscal year ended June 30, 1996
increased $5,334,124 from the prior year. The increase was attributable to
additional research collaboration agreements providing ongoing research
funding. Research revenue from the research collaboration agreements is
recognized as related costs are incurred. During the year, both the Ciba and
Bayer project teams hired additional researchers, resulting in increased
revenues to match the increased expenditures related to the new hires.
 
  Research and development expenses for the year ended June 30, 1996 increased
to $12,990,566 from $5,161,978 for the prior year. This increase was primarily
due to an increase in research as a result of the Company's collaborations
with Ciba and Bayer and an increase in research programs funded by the
Company, including third party research programs, increased depreciation
charges related to the purchasing of additional equipment, the hiring of
additional personnel and the associated increase in use of laboratory supplies
and reagents. The Company also incurred increased development expenses during
the year related to work on developing its predisposition test for mutations
of the BRCA1 and BRCA2 breast and ovarian cancer genes. The Company expects
research and development expenses to continue to increase as personnel and
research and
 
                                      21
<PAGE>
 
development facilities are expanded. Such expenses will also likely increase
to the extent that the Company enters into additional research agreements with
third parties.
 
  General and administrative expenses for the year ended June 30, 1996
increased $737,567 from the year ended June 30, 1995. The increase was
attributable to legal fees associated with filing worldwide patent
applications on the Company's gene discoveries, additional administrative
personnel, facilities-related costs and deferred compensation related to
grants of stock options and warrants. The Company expects that its general and
administrative expenses will continue to increase in support of its research
and development efforts and preparations for its genetic predisposition
testing business.
 
  Interest income for the year ended June 30, 1996 increased to $3,173,749
from $458,353 for the prior year. This increase was primarily due to the
increased funds available for investment, which were raised in the Company's
private placement of preferred stock in February 1995, its research and
development collaborations entered into with Ciba and Bayer in April 1995 and
September 1995, respectively, and its initial public offering in October 1995.
Interest expense for the year ended June 30, 1996, amounting to $97,414, was
due entirely to borrowings under the Company's equipment financing facility,
which are secured by equipment and have a repayment term of 48 months from the
date of funding. The other expense of $86,052 in the year ended June 30, 1996
is the result of a loss recognized on the sale of obsolete equipment. The net
loss increased to $5,897,473 for the year ended June 30, 1996 from $5,268,383
for the year ended June 30, 1995. The Company had federal income tax net
operating loss carryforwards of approximately $11,340,500 and federal income
tax research activities credit carryforwards of approximately $164,800 as of
June 30, 1996, which are subject to limitation as a result of changes in the
Company's ownership.
 
 Years ended June 30, 1995 and 1994.
 
  Revenues for the year ended June 30, 1995 increased by $694,500, which
includes approximately $180,000 from the Lilly collaboration as a result of
achieving a milestone related to the discovery of the BRCA1 gene and
approximately $500,000 under the Ciba collaboration agreement. Interest income
increased from $273,689 to $458,353 in fiscal 1995, primarily as a result of
interest on funds received from a private placement of securities and research
collaborations. Interest expense for the year ended June 30, 1995 amounting to
$71,011 was due entirely to borrowings under the Company's equipment financing
facility.
 
  Research and development expenses for the year ended June 30, 1995 increased
to $5,161,978 from $3,008,487 in fiscal 1994. The increase in 1995 was
primarily due to an increase in third party research programs funded by the
Company, the hiring of additional personnel, costs related to the expansion of
laboratory and office space, increased depreciation charges due to the
purchase of additional equipment and the use of higher volumes of supplies and
reagents.
 
  General and administrative expenses increased to $1,788,247 for the year
ended June 30, 1995 from $1,154,541 for the year ended June 30, 1994. The
increase in 1995 was primarily due to the hiring of additional administrative
personnel and the costs related thereto, facilities-related costs and deferred
compensation related to grants of stock options and warrants. The Company
recognized deferred compensation expense of $56,500 in 1995.
 
  The net loss increased to $5,268,383 for the year ended June 30, 1995 from
$3,276,775 for the year ended June 30, 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Net cash used in operating activities was $1,573,201 during the quarter
ended September 30, 1996 and $1,525,535 during the same quarter of 1995. Non-
trade receivables decreased $62,079 between June 30, 1996 and September 30,
1996 primarily as a result of the write-off of an uncollectable receivable.
Accounts payable and accrued expenses increased $461,839 between June 30, 1996
and September 30, 1996 primarily as a result
 
                                      22
<PAGE>
 
of the Company's purchase during the quarter of equipment to be installed in
the Company's new genetic testing facility.
 
  The Company's investing activities provided cash of $3,230,329 in the three
months ended September 30, 1996 and used cash of $13,099,006 in the three
months ended September 30, 1995. Investing activities in the quarter ended
September 30, 1996 were comprised primarily of capital expenditures for
research equipment, office furniture, and facility improvements and
reinvestment of marketable investment securities from long-term investments to
short-term cash equivalents. During the quarter ended September 30, 1995, the
Company had shifted its investment in marketable securities from short-term
cash equivalents to long-term investments.
 
  Financing activities used $48,228 during the quarter ended September 30,
1996. The Company reduced the principal on its equipment financing facility by
$74,186. This decrease was offset by proceeds of $25,958 from the exercise of
stock options. Financing activities provided $9,915,930 during the quarter
ended September 30, 1995. The Company reduced the principal on its equipment
financing facility by $66,793 and received an equity investment of
approximately $10,000,000 from Bayer during that time.
 
  The Company anticipates that its existing capital resources, including the
net proceeds of this offering, will be adequate to maintain its current and
planned operations for at least the next three years, although no assurance
can be given that changes will not occur that would consume available capital
resources before such time. The Company's future capital requirements will be
substantial and will depend on many factors, including progress of the
Company's research and development programs, the results and cost of clinical
correlation testing of the Company's genetic tests, the costs of filing,
prosecuting and enforcing patent claims, competing technological and market
developments, payments received under collaborative agreements, changes in
collaborative research relationships, the costs associated with potential
commercialization of its gene discoveries, if any, including the development
of manufacturing, marketing and sales capabilities, the cost and availability
of third-party financing for capital expenditures and administrative and legal
expenses. Because of the Company's significant long-term capital requirements,
the Company intends to raise funds when conditions are favorable, even if it
does not have an immediate need for additional capital at such time.

                                   BUSINESS
 
GENERAL
 
  Myriad Genetics, Inc. is a leader in the discovery and sequencing of genes
related to major common diseases, such as cancer and cardiovascular disease.
The Company utilizes analyses of extensive family histories and genetic
material, as well as a number of proprietary technologies, to identify
inherited mutations which increase the risk to individuals of developing these
diseases. The Company has also developed a proprietary high-throughput assay
to identify protein-protein interactions. The Company believes that the
application of these technologies may provide new insights into protein
function and cellular organization which may lead to the identification of
novel therapeutic targets. The discovery of disease-predisposing genes and
their biochemical pathways provides the Company with two significant
commercial opportunities: (i) the development and marketing of genetic testing
and information services, such as its recently launched BRACAnalysis(TM) test,
for the identification of individuals who are genetically predisposed to
developing a particular disease, and (ii) the development of therapeutic
products for the treatment and prevention of major diseases associated with
these genes and their biochemical pathways. The Company intends to pursue the
development of therapeutic products either in conjunction with its strategic
partners such as Ciba-Geigy Corporation ("Ciba"), Bayer Corporation ("Bayer")
and Eli Lilly and Company ("Lilly"), or independently.
 
  Myriad has achieved the following major milestones:
 
  . Discovered, with its academic collaborators, the complete sequence of the
     BRCA1 and BRCA2 breast and ovarian cancer predisposing genes. These two
     genes are responsible for the majority of early onset hereditary breast
     and ovarian cancers;
 
  . Launched its first commercial genetic predisposition test,
     BRACAnalysis(TM), a comprehensive BRCA1 and BRCA2 sequence analysis for
     susceptibility to breast and ovarian cancer;
 
  . Identified nine new genes that interact in the BRCA1 biochemical pathway
     and two new genes that interact in the BRCA2 biochemical pathway;
 
  . Discovered the tumor suppressor function of the cell cycle gene MTS1,
     which is responsible for the majority of hereditary melanoma, and
     discovered and sequenced two other cell cycle genes, MTS2 and MTS3, and
     is analyzing their potential role in cancer;
 
  . Discovered, with its academic collaborators, the chromosomal location of
     nine additional major genes, including genes involved in heart disease,
     cancer, osteoporosis and obesity;
 
  . Conducted approximately 2,000 DNA analyses in conjunction with an ongoing
     study by the National Institutes of Health to determine whether or not
     the Company's patented AGT gene mutations can be used to predict salt-
     dependent hypertension; and
 
  . Established strategic alliances with Bayer, Ciba and Lilly for the
     discovery of genes related to respiratory diseases and metabolic
     disorders, cardiovascular diseases and breast cancer, respectively.
     Under these agreements, the Company may receive up to an aggregate of
     $135 million in equity investments, research funding and milestone
     payments, as well as royalties on the sale of future therapeutic
     products. To date, the Company has received $32 million under the
     agreements.
 
  The Company has begun commercialization of its gene discoveries by providing
genetic tests for individuals to determine whether they have inherited gene
mutations which may increase their risk for specific diseases. On October 30,
1996, Myriad introduced BRACAnalysis(TM), an important genetic test for women
who have been diagnosed with breast or ovarian cancer and women who are at
risk for hereditary breast and ovarian cancer. The Company believes that
BRACAnalysis(TM) is the first comprehensive BRCA1 and BRCA2 sequence analysis
for susceptibility to breast and ovarian cancer. Women who may benefit from
BRACAnalysis(TM) include: women with a diagnosis of breast or ovarian cancer,
especially premenopausal breast cancer; women with a family history of breast
or ovarian cancer; and women with a blood relative who is known to have a
mutation in BRCA1 or BRCA2.
 
                                      24
<PAGE>
 
  Myriad has developed a highly automated genetic testing platform which the
Company believes will enable it, once it has discovered and sequenced a gene,
to develop a test for genetic predisposition relatively quickly and
economically. For example, the Company introduced BRACAnalysis(TM) in October
1996, less than one year after it discovered the full sequence of BRCA2. The
Company believes that the information gained from tests that confirm genetic
predisposition has potential value to individuals and their health care
providers in the following areas: (i) proactive health care and lifestyle
decisions that may delay or prevent the onset of disease; (ii) early detection
of disease; and (iii) selection of the most appropriate treatment. Through its
wholly-owned subsidiary, Myriad Genetic Laboratories, Inc. ("Myriad Labs"),
the Company has established a genetic predisposition testing laboratory which
has received federal certification under the Clinical Laboratory Improvements
Amendments Act of 1988 ("CLIA").
 
  In order to accelerate its gene discovery and therapeutic target
identification programs, the Company employs three synergistic sets of
technologies: (i) the genetic analysis of large Utah families performed by the
Company's scientists and collaborators; (ii) the Company's proprietary
bioinformatic gene mapping, sequencing and cloning technologies; and (iii) the
Company's advanced protein interaction and functional genomics technologies.
The Company's collaborators at the University of Utah and IHC Health Services,
Inc. ("IHC") have extensively studied large, multi-generational Utah families
with histories of high rates of certain diseases, including cancer and
cardiovascular disease. The clinical information from these studies, together
with genetic analysis of the more than 35,000 DNA samples collected from
family members, provides the Company with an unparalleled opportunity for
accelerating several critical steps of the gene discovery process. The Company
uses proprietary mapping and DNA sequencing technologies to identify a narrow
chromosomal region, to isolate candidate gene sequences and, ultimately, to
identify the actual DNA sequence comprising the disease-predisposing gene.
Once an important disease-predisposing gene has been identified, the Company
uses advanced protein interaction technologies to identify genes that are
upstream and downstream in the biochemical pathways from the gene discovered
in order to understand the biochemical pathways involved in the disease
process. This enables Myriad and its corporate partners to select promising
points of therapeutic intervention along the biochemical pathway.
 
  Myriad's business strategy has five primary components: (i) to expand the
Company's leadership position in discovering and sequencing genes; (ii) to
build the Company's genetic testing and information services business; (iii)
based on its gene discoveries, to identify potential therapeutic targets by
understanding the biochemical pathways related to common diseases; (iv) to
capitalize on strategic alliances with corporate partners to obtain financing
for a major portion of the Company's research and to commercialize certain
therapeutic products for the treatment and prevention of disease; and (v)
longer term, to pursue the independent marketing and development of
therapeutic products based on certain gene discoveries.
 
MYRIAD'S GENOMICS STRATEGY
 
  Myriad believes that the Company's strategy of combining the three major
approaches to the discovery and sequencing of genes (positional cloning, high-
speed DNA sequencing and protein interaction network analysis) greatly
increases the probability that the genes discovered will be of diagnostic and
therapeutic importance. The focused and direct application of these three
approaches at the appropriate stage of the gene discovery process enables the
Company to discover and sequence important disease-related genes relatively
quickly and economically. Starting with a disease target such as breast
cancer, the Company first utilizes positional cloning, having determined in
advance of sequencing that the gene being sought in fact contributes to a
substantial percentage of incidence of a particular disease and thus may have
significant commercial potential. The Company's positional cloning strategy is
based on the presence of a specific disease-related chromosomal fragment
shared by many individuals within a multi-generational family. The Company
uses positional cloning to reduce the library of candidate genes from tens of
thousands to ten or fewer genes on a specific chromosome.
 
  Myriad has developed proprietary high-speed DNA sequencing technologies that
enable the Company to efficiently and rapidly obtain sequences from the
chromosomal region and sequence the entire gene once it has been identified.
Following the identification of the disease-related gene, the Company uses
protein interaction technologies to identify other related genes that may
yield additional diagnostic or therapeutic opportunities.
 
                                      25

Myriad identifies genes that interact with the disease-predisposing gene in
order to understand the biochemical pathway associated with the disease. The
success of the Company's approach is demonstrated by its discovery of the
complete sequence of five major genes (BRCA1, BRCA2, MTS1, MTS2 and MTS3) and
the identification of eleven genes along their biochemical pathways.
 
  All stages of the gene discovery process use and generate a vast amount of
information. Accordingly, the Company has designed a proprietary
bioinformatics system which provides significant analytical and data
management capabilities which are integral to genetic and molecular analysis.
The system is based on integrated, protocol-driven database management
software which is utilized to track experiments and collect the data
generated. The system incorporates data on DNA samples, genetic markers, maps,
DNA clones and DNA sequences which are generated during the gene discovery
process. Further, the system directs the genetic analysis, fine structure
mapping, generation of candidate genes and mutation screening. It allows the
automation of labor intensive steps in the analysis of DNA sequences, and
incorporates Myriad's expert system for detecting coding regions in random DNA
sequences. Proprietary software methods have also been developed by scientists
at the Company which significantly accelerate mutation screening.
 
  Myriad leverages its proprietary database of families to link important
disease causing genes to specific chromosomes. The Company then employs its
proprietary high-speed sequencing technologies to discover these disease-
causing genes, which leads directly to two important commercial opportunities
for the Company: (i) genetic testing products such as BRACAnalysis, the first
comprehensive sequence-based genetic test, and (ii) gene therapy and protein
replacement therapy products. Once an important disease-causing gene has been
discovered, the Company employs proprietary protein interaction technologies
to identify the upstream and downstream genes along its biochemical pathway.
Company scientists also establish functional assays to determine the function
and activity of the protein produced by the disease-causing gene.
Understanding the biochemical pathway and protein function lead to novel
therapeutic targets that the Company uses to develop new therapies in
conjunction with its corporate partners and independently.
 
  Studying Diseases in Families. A key competitive advantage of the Company's
gene discovery process is the information derived from the genetic analysis of
large, multi-generational Utah families. The early Utah population was
characterized by many large families with a dozen or more children, hundreds
of grandchildren and great-grandchildren and thousands of descendants. By
using the extensive and detailed genealogical records kept by the families
themselves, the Company is better able to resolve the ambiguities caused by
interactions between environmental factors and multiple predisposition genes.
Although in practice combining data from several multi-generational families
is more efficient, the Company can often positionally clone a gene related to
a disease by studying DNA from a single large extended family. For example,
the Company was able to clearly identify the region encompassing the BRCA2
gene in the largest known extended family carrying that trait. This type of
analysis is not possible using small families because the interactions between
environmental factors and multiple causal genes may lead to erroneous
conclusions regarding the chromosomal location of a gene.
 
  To efficiently identify common disease-predisposing genes, the Company has
entered into several exclusive research collaborations. In the field of
cancer, the Company is currently working with researchers at the University of
Utah's Center for Cancer Genetic Epidemiology whose analysis of familial
cancers contributed significantly to the understanding of the hereditary
nature of most types of cancer. These researchers have collected over 25,000
DNA samples from extended families with breast cancer, ovarian cancer, colon
cancer, prostate cancer, lung cancer, bladder cancer, brain cancer, leukemia,
lymphoma and melanoma. In the cardiovascular and obesity fields, the Company
is currently working with researchers at the University of Utah's
Cardiovascular Genetics Research Clinic, which has an extensive collection of
data from extended families with cardiovascular disease and obesity,
encompassing over 10,000 DNA samples collected to date. Research with IHC
collaborators currently involves the study of families with asthma and
families with osteoporosis. Myriad's University of Utah and IHC colloborators
are currently collecting over 6,000 new DNA samples per year.
 
  Analyzing DNA from Family Members. The DNA from selected members of each
extended family is analyzed with a large set of genetic markers, enabling
researchers to identify which chromosomal segment is associated with a
particular disease in a family. The family members' DNA sample preparations
are quality controlled, and then placed on a robotics workstation which
prepares thousands of polymerase chain reaction
 
                                      26
<PAGE>
 
("PCR") amplifications of the genetic markers and, after amplification,
combines the reaction products so that all of the genetic markers for a
complete genomic search can be analyzed on automated sequencers. For example,
all of the genetic markers for ten family members in an extended family can be
gathered in a single day, creating enough information to begin mapping the
underlying gene to a specific chromosomal region.
 
  Locating and Narrowing the Chromosomal Region on which the Gene Resides. The
genetic markers from the DNA of family members are stored in the Company's
proprietary database system and complex analysis programs search for the
chromosome on which the gene resides. As candidate chromosomal regions are
found, additional sets of markers in the suggested regions are analyzed and the
set of families and family members studied is expanded to narrow the gene's
location. Once a gene has been located on a particular chromosome, the Company
uses recombinant DNA libraries to select DNA fragments which encompass the
region surrounding the gene. The Company has acquired an extensive genomic
library for mapping and gene isolation. By using a proprietary procedure
developed at Myriad, the chromosomal region is significantly narrowed by
tracing patterns of inheritance of new genetic markers which are isolated from
the clones encompassing the region.
 
  Identifying the Disease-Predisposing Gene and Characterizing Mutations. The
Company uses high-speed gene sequencing to screen all genes in the narrowed
region to identify mutations that are present in the DNA sequences of diseased
individuals and are absent in the DNA sequences of unaffected individuals. To
find the set of candidate genes in the chromosomal region, the Company uses two
proprietary approaches developed by Myriad scientists, a DNA sequencing
methodology in conjunction with gene detection software, and a high-throughput
method for identifying expressed sequences. Gene fragments identified in this
manner are extended to include the entire gene sequence by the Company's
"directed hybrid selection" technology. The disease-related gene is identified
by detecting sequence variants using automated sequencing and Myriad's
proprietary sequence analysis software. This automatic detection greatly
increases the speed at which genes can be screened for disease-predisposing
mutations.
 
  Once a disease-related gene has been discovered, Myriad scientists examine
DNA from affected and unaffected individuals to estimate the frequency of each
mutation and its associated disease risk in a variety of populations. Relatives
of each individual carrying a disease-related gene are tested for the presence
of the specific mutations. The information derived from these tests has enabled
the Company to develop a large and growing proprietary database to characterize
each mutation by type, severity and age of onset of the associated disease. In
certain cases, functional assays are developed to test the predisposing
activity of each mutation.
 
  Identifying the Biochemical Pathway. As protein-protein interactions mediate
the functions of most cellular processes, identification of such interactions
is critical in understanding a protein's function. Accordingly, the Company has
developed a proprietary high-throughput version of an assay to identify
protein-protein interactions. This system employs the Company's integrated
automation platform and significant bioinformatics capabilities to rapidly
identify protein partners. The Company believes that the application of this
technology may provide new insights into protein function and cellular
organization and may suggest functions for known and novel proteins.
Ultimately, the analysis of large numbers of protein interactions may allow the
Company to identify critical interactions that could be targets for therapeutic
intervention.
 
  This technology is also applied to characterize the component pathway
proteins involved in these diseases. Functional assays are developed to analyze
the relationship of these pathway components to the function of the disease
gene. In addition, predisposing mutations in the disease gene are tested for
their effect on interactions with various protein partners to identify critical
components of the disease pathway.

MYRIAD'S GENE DISCOVERY PROGRAMS
 
  Myriad's research programs are focused on the discovery of disease-related
genes which predispose individuals to cancer, cardiovascular diseases and
other common diseases. The following table summarizes the current status of
the Company's gene discovery programs:

<PAGE>
 
  The Company's gene discovery and development programs in cancer,
cardiovascular diseases and other major diseases are described in further
detail below.
 
CANCER
 
  Scientists and physicians understand that many common disorders have a
strong hereditary component. These diseases, including cancer, involve genetic
changes that affect millions of individuals. Individuals genetically
predisposed to cancer have a disease-related mutation in one of the two copies
of a gene they inherit from their parents. Thus, one step that can lead to
cancer has already occurred in every cell of that individual.
 
  BRCA1 Breast and Ovarian Cancer Gene. The Company and its collaborators
reported the discovery of the BRCA1 breast and ovarian cancer predisposing
gene in the October 7, 1994 issue of the journal Science. Familial, hormonal
and environmental factors can each influence a woman's risk of developing
breast or ovarian cancer. In 1996, it is estimated that approximately 184,000
women in the United States will be diagnosed with breast cancer and an
additional 27,000 women will be diagnosed with ovarian cancer. During the same
period, an estimated 44,000 women will die from breast cancer (the second
highest cancer mortality rate among women) and an estimated 15,000 women will
die from ovarian cancer. BRCA1 appears to be responsible for approximately
half of the early onset hereditary breast cancer cases in an international
study of breast cancer conducted by the Breast Cancer Linkage Consortium (the
"Consortium Study"). Hereditary breast cancer is believed to account for
approximately 5-10% of all cases of breast cancer. A study of women in the
United States published in the American Journal of Human Genetics indicates
that a woman with a BRCA1 mutation has an 86% risk of developing breast cancer
by age 80 as compared to a general population risk of 10%. Additionally,
according to a recent study published in Lancet, the risk to a woman with a
BRCA1 mutation of developing ovarian cancer by age 70 is approximately 44%,
compared to a general population risk of approximately 1%.
 
  The Company believes that women who have relatives with breast or ovarian
cancer, and therefore may have a higher risk of developing breast or ovarian
cancer, will want to know if they have a BRCA1 mutation. A study recently
published by the Journal of Clinical Oncology of women who had at least one
relative with ovarian cancer found that 75% of the women surveyed would
definitely want to be tested for the existence of a BRCA1 mutation and 20% of
the women surveyed would probably want to be tested, while only 2% would not
want to be tested. The remaining 3% were uncertain.
 
  BRCA2 Breast Cancer Gene. On December 20, 1995, Myriad and its collaborators
announced the discovery of the complete sequence of BRCA2, a second hereditary
breast cancer gene which was found to be responsible for the majority of the
remaining cases of inherited breast cancer, as reported in the journal Nature
Genetics. Myriad has developed a genetic test for this gene which has been
combined with the test for BRCA1 to form a comprehensive integrated test for
hereditary breast and ovarian cancer.
 
  Women who inherit a mutated copy of the BRCA2 gene also have an increased
risk of early onset breast cancer, and men with mutations in BRCA2 are also at
increased risk for developing the rare form of male breast cancer. A number of
distinct mutations have been identified by the Company for BRCA2 in breast
cancer families. BRCA2 mutations are thought to account for a large proportion
of the remaining early onset hereditary female breast cancers which are not
accounted for by BRCA1, as well as most hereditary male breast cancers. Women
with BRCA2 mutations have approximately the same risk of breast cancer as
BRCA1 mutation carriers; the risk of ovarian cancer is also increased,
although not as much as in those with BRCA1 mutations.
 
  MTS1 Tumor Suppressor Gene. The Company's first major discovery was the
involvement of the MTS1 gene in the formation of many types of cancer
including melanoma, lymphoma, leukemia and cancers of the lung, breast, brain,
bone, bladder, kidney and ovary. The role of MTS1 as a tumor suppressor was
discovered by Myriad and was reported in the April 15, 1994 issue of the
journal Science. When MTS1 is mutated, its function as a molecular brake
during a key step in the cell division process is lost and uncontrollable cell
growth may
 
                                      29
<PAGE>
 
take place. Myriad has shown that MTS1 is deleted or mutated in over half of
all tumor cell lines tested. Because MTS1 is one of the most commonly mutated
or deleted tumor suppressor genes discovered to date, Myriad believes that it
is a promising candidate for the development of new anti-cancer therapies. The
MTS1 gene may also have value in monitoring disease progression.
 
  Myriad also discovered that abnormal MTS1 genes can be inherited, and that
when they are inherited they predispose individuals to melanoma. The Company's
discovery of the MTS1 predisposition to melanoma was reported in the September
1994 issue of the journal Nature Genetics. Melanoma is lethal in 86% of cases
where it has metastasized (spread to another site in the body); however, when
it is diagnosed at an early stage, less than 10% of patients die within five
years. Since the early 1970's, the incidence of melanoma has increased at
about 4% per year and melanoma has become one of the fastest growing cancers
in the United States. In 1996 it is estimated that approximately 38,000
Americans will be diagnosed with melanoma. The Company believes that
approximately 10% of melanoma cases are hereditary. The Company and its
collaborators have substantial expertise in the genetic analysis of melanoma
and have begun to identify important disease-predisposing MTS1 mutations.
 
  MTS2 and MTS3 Cell Cycle Genes. Myriad scientists located MTS1 on a narrow
region of chromosome 9. Further analysis of this region yielded two other
novel genes involved in cell growth and cell cycle control, MTS2 and MTS3.
Although other researchers sequenced a portion of MTS2, the Company discovered
that MTS2's expression levels increased during DNA replication and cell
division. Myriad also discovered MTS2's potential involvement in cancer and is
investigating its specific potential role in several types of cancer. Myriad's
discovery of the MTS3 gene has led to a new area of research in cell division
and its possible role in cancer.
 
  CA4, CA5, CA6 and CA7 Cancer Genes. The Company also has active research
programs to identify additional genes believed to be implicated in cancer.
Studies by the Company and its collaborators are focused on all of the major
cancer sites including prostate cancer, colorectal cancer, lung cancer, brain
cancer, leukemia and lymphoma, all of which have a strong hereditary
component. To date, Myriad and its academic collaborators have determined the
chromosomal location of CA4, CA5 and CA7, genes associated with three major
types of cancer, to small chromosomal regions, and have discovered a novel
tumor suppressor gene, CA6. It is estimated that over 400,000 new cases of
these cancers will be diagnosed each year in the United States.
 
CARDIOVASCULAR DISEASES
 
  Scientists recognize that cardiovascular diseases represent a group of
related disorders that are highly familial and result from both genetic and
environmental risk factors. Genetic predisposition to cardiovascular diseases
involves a number of familial risk factors including, among others, abnormal
levels of triglycerides (fats used for storage and energy), cholesterol,
angiotensinogen (a protein involved in the regulation of salt and water
retention) and homocysteine (an amino acid involved in blood coagulation), all
of which may interact with environmental risk factors, such as physical
activity, stress, smoking and diet.
 
  AGT Hypertension Gene. Hypertension (high blood pressure) is a complex
disorder which is believed to have a number of causes, including excess
weight, atherogenesis (formation of fat deposits on the interior walls of
arteries) and salt sensitivity. Approximately 50 million people in the United
States are hypertensive. Hypertension has a significant genetic component and
is a major risk factor for cardiovascular disease, kidney failure and stroke.
The angiotensinogen ("AGT") gene is believed to be involved in salt-dependent
hypertension. Certain mutations in the AGT gene are believed to cause
individuals to retain excessive amounts of salt, thus increasing their risk
for hypertension. The U.S. Patent Office issued a patent on a method for
detecting a predisposition to hypertension based on the AGT gene to the
University of Utah and Institute National de la Sante et de la Recherche
Medicale ("INSERM") in December 1994. The Company has an agreement with the
University of Utah and INSERM, pursuant to which it has a co-exclusive license
to develop diagnostic products from the genetic mutations of AGT associated
with hypertension, and an exclusive license to develop therapeutic products
from such genetic mutations of AGT.
 
 
                                      30
<PAGE>
 
  CHD1 and CHD2 Heart Disease Genes. Heart disease is the leading cause of
death in the United States and is believed to have a significant genetic
component. Approximately 1.5 million acute myocardial infarctions (heart
attacks) result in 800,000 hospitalizations and more than 500,000 deaths each
year in the United States. The Cardiovascular Genetics Research Clinic at the
University of Utah has assembled a database of approximately 120,000 families
comprising over 1,000,000 individuals and has identified a large number of
families with a strong history of cardiovascular disease.
 
  Myriad has determined the location of two significant cardiovascular disease
genes, CHD1 and CHD2, each within a narrow region of a chromosome. The Company
believes that the CHD1 and CHD2 genes are important predisposing genes for
heart disease, since approximately 15% of families studied with early coronary
heart disease have the condition associated with these genes. The Company
believes that a genetic test for familial cardiovascular disease would be of
value to predisposed individuals, who could benefit from regular monitoring.
The discovery of the CHD1 and CHD2 genes may facilitate early diagnosis and
improved therapeutic products.
 
OTHER MAJOR DISEASES
 
  MOB1 and MOB2 Obesity Genes. There are approximately 34 million adult
Americans who are classified as obese. The mechanisms of fat storage and
energy balance have a substantial hereditary component, and the Company
believes that a gene or combination of genes is likely to be responsible for a
significant percentage of obesity. It has not been established that the human
counterparts of the rare obesity genes recently discovered in mice play a
significant role in common human obesity. Myriad believes that its
collaborator's collection of DNA from members of extended families who are
obese give it a competitive advantage in the search for human obesity genes.
Myriad's scientists have determined the chromosomal locations of two
significant obesity genes, MOB1 and MOB2. The Company believes that the MOB1
and MOB2 genes are important in human obesity and may be responsible for a
majority of hereditary obesity.
 
  OS1 Osteoporosis Gene. Osteoporosis is a disorder of decreasing bone mass
affecting approximately one quarter of women over age 60, nearly half of all
women over 75 and approximately 25 million individuals in the United States.
Osteoporosis is the most significant underlying cause of skeletal fractures
among late middle-aged and elderly women. Early detection of a predisposition
to osteoporosis is important because nutritional and therapeutic intervention
can delay the onset and reduce the severity of the disease. Myriad has
determined the location of a significant gene involved in osteoporosis, OS1,
and has narrowed the OS1 gene to a small region of a chromosome. The Company
believes that the OS1 gene plays an important role in the pathogenesis of
osteoporosis.
 
  Asthma Genes. It is estimated that between 10 and 15 million people in the
United States have asthma and there is strong evidence supporting the
existence of a genetic component to asthma. Deaths from severe asthma attacks
have been increasing in the United States and now number approximately 6,000
per year. Detailed case reviews suggest that many deaths from asthma could
have been prevented by earlier and more intensive medical care. There is
currently no laboratory test which can establish a diagnosis of asthma. Myriad
and its collaborators have begun systematic collection of data from families
with a history of asthma and have also begun chromosomal location analysis.
 
  Diabetes Genes. Type II diabetes is a complex disorder resulting from the
body's failure to process blood sugar properly. It is estimated that
approximately 17 million people in the United States are affected by type II
diabetes. It is difficult and cumbersome to diagnose type II diabetes at an
early stage. Early detection of a predisposition to type II diabetes is
important because diabetes may cause tissue damage and may also increase an
individual's risk for heart disease, stroke, and high blood pressure. The
Company anticipates a significant market for a genetic predisposition test for
diabetes. The Company is developing a large database of information on
families afflicted with diabetes.
 
  Depression and Bipolar Disease Genes. There are approximately 13 million
people in the United States that are affected by major depression and an
additional approximately 4 million in the United States with bipolar disorders
or manic depression. In June 1996, the Company entered into a research
collaboration with IHC to link IHC's medical data and patient records of
individuals with disorders of the central nervous system with the Company's
proprietary database of families.
 
                                      31
<PAGE>
 
  Attention Deficit-Hyperactivity Disorder ("ADHD") and Addictive Behavior
Genes. ADHD is often cited as the most common behavioral problem among school-
aged children. Estimates of the number of children and adolescents in the
United States with ADHD range from 1.4 to 2.2 million or approximately 3-5% of
the population. The disease generally has its onset before the age of seven
years with symptoms of inattention, impulsivity and hyperactivity which persist
for longer than six months. Addictive behaviors are led in prevalence by
alcoholism, which has been described as the third largest health problem in the
United States behind heart disease and cancer. Alcoholism affects 13.8 million
people, costs $98.6 billion and is implicated in 100,000 deaths annually. A
recent study in Archives of General Psychiatry indicates that men with a family
history of alcohol dependence are more than twice as likely to develop
dependence on alcohol themselves, compared to men with no family history. The
Company is currently studying families with ADHD and addictive behavior
problems to identify candidate groups for analysis.
 
MYRIAD'S PRODUCT DEVELOPMENT PROGRAMS
 
  The Company has identified two commercial opportunities arising from the
discovery of genes which predispose individuals to common diseases: (i) the
development and marketing of genetic testing and information services for the
identification of individuals who are genetically predisposed to developing a
particular disease, such as its recently launched BRACAnalysis(TM) test, and
(ii) the development of therapeutic products for the treatment and prevention
of major diseases. The Company intends to pursue the development of therapeutic
products either in collaboration with its corporate partners or independently.
 
  The following table summarizes the current status of the Company's product
development programs:
 
 
[Table summarizing the status of the three genetic predisposition tests 
developed or under development by the Company.]
 

BRACANALYSIS(TM) GENETIC PREDISPOSITION TEST
 
  On October 30, 1996, the Company introduced BRACAnalysis(TM), a comprehensive
BRCA1 and BRCA2 sequence analysis for susceptibility to breast and ovarian
cancer. The introduction followed the successful pre-market evaluation of the
test in 14 leading U.S. cancer centers. BRACAnalysis(TM) provides women and
their family members who are at risk for hereditary breast and ovarian cancer
with important information that the Company believes will help them and their
physicians make better informed lifestyle, dietary, surveillance and treatment
decisions.
 
  BRACAnalysis(TM) is a fully automated testing platform that can deliver a
direct full sequence analysis of BRCA1 and BRCA2 to women who seek knowledge of
their predisposition to cancer. The Company believes that women who may benefit
from BRACAnalysis(TM) include: women with a diagnosis of breast or ovarian
 
                                       32
<PAGE>
 
cancer, especially premenopausal breast cancer; women with a family history of
breast or ovarian cancer; and women with a blood relative who is known to have
a mutation in BRCA1 or BRCA2. Because genetic predisposition testing raises
important medical, psychological and social issues for patients and their
families, Myriad Labs recommends that individuals meet beforehand with a
genetic counselor or other trained health care professional to discuss the
potential benefits and limitations of genetic predispositon analysis.
Physicians are required to confirm that an informed consent was obtained from
each patient prior to testing.
 
  In order to have the test performed, an individual visits his or her
physician or health care provider and a blood sample is obtained, placed in a
bar coded test tube and forwarded to Myriad Labs for processing. Upon receipt
by Myriad Labs, each sample is logged for sample tracking and is then handled
by advanced robotic systems to process the sample and perform the genetic
test. BRACAnalysis(TM) identifies mutations in the BRCA1 and BRCA2 genes
through a process that involves the performance of over 80 separate PCR
amplifications and the sequencing of more than 33,000 DNA base pairs from the
individual's blood sample. For the majority of women, BRACAnalysis(TM)
includes a full sequence analysis of the protein-coding regions of both the
BRCA1 and BRCA2 genes. However, in individuals who have a relative with a
known BRCA1 or BRCA2 mutation, the Company can perform a mutation-specific
test known as single-amplicon analysis.
 
  The Company expects that the ordering physician will receive an analysis
from Myriad Labs within three to four weeks. If a deleterious mutation is
detected, or if a mutation is identified whose clinical significance is not
known, the Company's medical or laboratory director contacts the physician by
telephone to discuss the results. In validation tests at Myriad, the testing
platform achieved a sensitivity of greater than 98% (false negative of less
than 2%) and a specificity of greater than 99% (false positive of less than
1%). Myriad encourages post-test counseling and education for all patients by
providing physicians with educational materials and genetic counselor referral
guides.
 
  In preparation for the commercial introduction of BRACAnalysis(TM), the
Company hired a sales force with regional responsibilities for sales,
promotion and education of physicians nationwide. The Company currently
employs a sales force of five individuals and expects to significantly expand
its sales force over the next three years. Marketing and educational efforts
initially have been directed to approximately 50 comprehensive cancer centers,
500 community cancer centers, 9,000 oncologists and 40 of the largest managed
care organizations as primary customers for BRACAnalysis(TM). Myriad also
conducts educational symposiums for physicians in conjunction with the major
medical conferences across the country, most recently at the American College
of Surgeons meetings in San Francisco and the American College of
Obstetricians and Gynecologists meetings in Denver. The Company has
distributed over 100,000 educational packets to physicians, health care
providers and genetic counselors. Educational efforts are also underway to
secondary customer segments which include obstetricians, gynecologists and
primary care physicians. The Company believes that broad market acceptance can
be achieved only with substantial education about the benefits and limitations
of BRACAnalysis(TM), as well as efforts to resolve concerns about their
appropriate and ethical use.
 
  The Company has engaged a reimbursement consulting company to assist it in a
number of reimbursement activities for BRACAnalysis(TM), including: (i)
working with the Company to secure reimbursement approval from insurance and
managed care organizations for reimbursement for BRACAnalysis(TM); (ii)
providing reimbursement assistance through an 800 number hotline for patients
who wish to file claim forms with their insurance companies or managed care
providers; and (iii) administering a free of charge financial assistance
program for uninsured patients who meet financial means criteria for
BRACAnalysis(TM). While reimbursement policies for BRACAnalysis(TM) are still
under discussion with a number of insurance companies and managed care
providers, a major HMO announced in 1996 that it plans to reimburse BRCA1
testing to its members. The Company will require patients to pay directly for
BRACAnalysis(TM) when insurance coverage or financial assistance is not
available, although there can be no assurance that individuals will elect to
pay directly for the test.
 
  The Company has established a list price for BRACAnalysis(TM) of $2,400 for
full sequence tests and $395 for single amplicon tests for family members of
individuals who have been identified by the Company as carrying specific
mutations. The Company has established the pricing structure based on the
complexity, sophistication and potential usefulness of the test information
for patients and their physicians. A key component in the
 
                                      33
<PAGE>
 
reimbursement decision by the United States Health Care Financing
Administration ("HCFA") and most private insurers is the development of
Current Procedural Terminology ("CPT") codes, which are used in the submission
of claims to insurers for reimbursement for medical services. CPT codes are
developed, maintained and revised by a committee of medical specialists which
is administered by the American Medical Association ("AMA"). Currently,
reimbursement for genetic tests is made on the basis of CPT codes which may
not accurately reflect the complexity of sophistication of specific genetic
tests. The Company has petitioned the CPT committee for test-specific codes
which better reflect the complexity, sophistication and resource utilization
of the Company's planned genetic tests. Additionally, new CPT sequencing
codes, scheduled for implementation in 1998, are currently under review by the
AMA. There can be no assurance that the Company will succeed in securing
recognition by the CPT committee of specific codes for its products and
services. Failure to secure recognition by the CPT committee could have a
material adverse effect on the Company.
 
  Although the BRACAnalysis(TM) test has been successfully tested at 14
leading cancer centers across the country, there can be no assurance that this
test or other similar tests developed by the Company in the future will
achieve overall market acceptance. The degree of market acceptance will depend
on a number of factors, including the availability of third-party
reimbursement and demonstration to the medical community of the value,
efficacy and cost-effectiveness of the test to patients, payors and health
care providers.
 
AGTANALYSIS GENETIC PREDISPOSITION TEST
 
  The Company is also in the process of developing the AGTanalysis genetic
predisposition test, a fully automated testing platform that can identify
specific mutations of the AGT gene to assess an individual's risk of salt-
dependent hypertension. The Company believes that the AGTanalysis may also be
useful to determine which individuals diagnosed with hypertension may benefit
from a low sodium diet therapy. Together with the National Institutes of
Health ("NIH") , the Company is currently engaged in a study of the AGT
genotypes of approximately 2,000 individuals with hypertension to determine
whether an individual's ability to lower blood pressure by following a low
sodium diet is correlated with the presence of certain AGT mutations.
Demonstration of these correlations could validate the use of the AGT genetic
test to assist health care providers in selecting the most effective therapy.
Scientists at the Company have completed the development of the AGT genetic
test for salt-dependent hypertension and are prepared to introduce the test if
a correlation is established in the studies.
 
MTSANALYSIS GENETIC PREDISPOSITION TEST
 
  The Company and its collaborators have begun to identify important disease-
predisposing MTS1 mutations. Similar to the BRACAnalysis(TM) test and the
proposed AGTanalysis test, the Company is in the process of developing a
genetic predisposition test to detect mutations to the MTS1 gene. The Company
believes that an MTSanalysis test will assist individuals in determining if
they are at risk for hereditary melanoma, a potentially lethal disorder which
is curable if detected early. Melanoma has become one of the fastest growing
cancers in the United States. The Company is in the early stages of
development of an MTSanalysis test and there can be no assurance that the
Company will successfully develop or commercialize this product.
 
MYRIAD'S COMMERCIALIZATION STRATEGY
 
  Myriad's initial commercialization strategy is to develop and market genetic
testing and information services for the identification of individuals who
have a high genetic risk of developing a particular disease based on
predisposing genes discovered or licensed by the Company. The development of
therapeutic treatments for such diseases represents a longer term opportunity
for the Company to pursue in collaboration with strategic partners or
independently. The Company has established a commercial genetics laboratory to
provide genetic predisposition testing and has received CLIA laboratory
certification from the Department of Health and Human Services. Myriad began
marketing the first such genetic predisposition test, BRACAnalysis(TM), on
October 30, 1996. The Company believes that the genetic information business
represents an attractive opportunity for the following reasons:
 
  . The discovery of a gene enables the Company to develop and introduce a
     commercial test for genetic predisposition in a shorter period than the
     time required for therapeutic product development;
 
                                      34
<PAGE>
 
  . The cost of developing a genetic test is significantly less than the cost
    of developing a therapeutic product;
 
  . The identification and patenting of genes may create significant barriers
    to other companies attempting to enter the field;
 
  . The market for genetic predisposition testing for cancer, heart disease
    and other common diseases potentially includes a very large segment of
    the population, since the Company believes that many individuals can
    benefit from information regarding their susceptibility to these
    diseases;
 
  . The Company's broad technology platform should permit it to identify a
    number of disease-predisposing genes and to develop the related genetic
    predisposition tests; and
 
  . The Company's gene discoveries provide longer-term opportunities for the
    Company to develop and commercialize therapeutic products.
 
  The Company believes that the information gained from genetic tests that
confirm inherited disease predisposition has potential value in the following
areas: (i) proactive health care and lifestyle decisions that may delay or
prevent the onset of disease; (ii) early detection of disease which may
improve outcomes; and (iii) selection of the most appropriate treatment once
an individual develops a disease.
 
 Genetic Predisposition Testing and Information Business
 
  Through Myriad Labs, the Company has established a central genetic testing
laboratory to provide genetic information services to health care providers
based on the genes discovered by the Company. The Company is developing a
clinical database of information on mutations of each gene discovered,
including the frequencies of occurrence in different population groups and the
clinical correlation of these mutations. This database will permit Myriad Labs
to provide health care professionals with detailed genetic information
regarding the risk profile associated with an individual's genetic test
results. Myriad Labs also provides educational and support services to
physicians and health care professionals as part of its genetic information
business.
 
  There are numerous difficulties and challenges associated with developing
genetic tests based on gene discoveries, as well as uncertainties in
interpreting the results. A defective gene may malfunction in many ways, and
the numerous mutations of the gene may make tests for the mutations difficult.
In addition, even when a genetic test identifies the existence of a mutation
in a particular individual, the interpretation of the genetic test results is
limited to the identification of a statistical probability that the tested
individual will develop the disease for which the test has been completed.
There can be no assurance that the Company will be successful in developing
genetic tests in addition to BRACAnalysis(TM) or that BRACAnalysis(TM) or any
such tests will be able to be marketed at acceptable prices or will receive
commercial acceptance in the markets that the Company expects to target.
 
  By targeting its gene discovery efforts to the genetic predisposition
components of major common diseases such as cancer and cardiovascular disease,
the Company believes it will be able to assist health care providers in
determining an individual's predisposition to such illnesses. The Company
believes that genetic predisposition testing will be of great medical value to
large segments of the population. Both affected individuals and those who are
not currently affected but have a high risk of developing the disease in the
future can benefit from the genetic test information which will enable them to
make more informed decisions concerning selection of the most appropriate
therapy, increased monitoring and preventive measures.
 
  In the longer term, the Company believes that as more genes are added to its
portfolio through discoveries by the Company and licenses of genes discovered
by others, the Company may be positioned to offer an array of genetic tests
which cover a number of major diseases. The availability of a broad genetic
testing profile could lead to expanded markets encompassing substantial
additional segments of the population who could benefit from knowing their
risk of developing a variety of major diseases.

 Therapeutic Opportunities
 
  Genes control all physiological processes through the expression of
proteins. Genetic disease manifests itself when a gene produces a protein that
causes a harmful effect or fails to produce a protein necessary for good
health. For example, a mutated gene may express a protein that causes certain
cells to proliferate without control, causing cancer. The Company believes
that the technologies it has developed to identify genes and their biochemical
pathways will enable it to identify important proteins for therapeutic
intervention. Preventing or treating disease involves, either (i) intervening,
through the use of a drug, in the complex series of cellular processes (which
may include a series of receptor, enzyme, hormone and other protein
interactions in the biochemical pathway) that blocks the activity of a harmful
protein or replaces the function of a beneficial protein; (ii) replacing,
modifying or regulating the gene responsible for a beneficial or harmful
protein, or (iii) replacing a beneficial protein.
 
STRATEGIC ALLIANCES
 
  The Company seeks to obtain financing for a portion of its research and
development activities through strategic alliances with corporate partners and
endeavors to leverage its research efforts through collaborative agreements
with academic institutions. Myriad has formed strategic alliances with three
major pharmaceutical companies to date. The Company is collaborating (i) with
Ciba to discover genes involved in certain types of cardiovascular disease,
(ii) with Bayer to discover genes involved in obesity, osteoporosis and asthma
and (iii) with Lilly to commercialize the BRCA1 breast and ovarian cancer
gene. The Company is actively pursuing strategic alliances with other partners
in areas where it believes they may enhance the Company's ability to develop
and exploit its technology. The material terms of the Company's current
strategic alliances and collaborative agreements are described below.
 
 Ciba-Geigy Corporation
 
  In April 1995, Myriad entered into a Collaborative Research and License
Agreement and Stock Purchase Agreement with Ciba. Under the agreements, Ciba
made a $7 million equity investment in the Company and agreed to provide $25
million of funding over a five-year period to support the Company's research
and development programs to identify and sequence certain genes involved in
cardiovascular disease. In addition, the Company may receive future milestone
payments up to $28 million and future royalty payments on therapeutic product
sales. The Company granted Ciba an exclusive, worldwide license to develop,
manufacture and sell therapeutic products derived from genes described above.
Ciba may terminate the research agreement after April 1997 if the Company
fails in a material respect to achieve any of the research objectives
established by the research steering committee, which is comprised of an equal
number of representatives from the Company and Ciba.
 
  Under the Ciba agreements, the Company will retain the exclusive, worldwide
rights to all diagnostic products and genetic testing services based on the
genes discovered under the research collaboration. The Company will retain the
exclusive, worldwide rights to any therapeutic or diagnostic product for
animal health care. In addition, Ciba has certain registration rights with
respect to the stock it purchased under the agreements as well as certain
Board representation rights.
 
 Bayer Corporation
 
  In September 1995, Myriad entered into a Collaborative Research and License
Agreement and Stock Purchase Agreement with Bayer. Under the agreements, Bayer
made a $10 million equity investment in the Company and agreed to provide $25
million of funding over a five-year period to support the Company's research
and development programs to identify and sequence genes involved in obesity,
osteoporosis and asthma. In addition, the Company may receive future milestone
payments up to $36 million and future royalty payments on therapeutic product
sales. The Company granted Bayer an exclusive, worldwide license to develop,
manufacture and sell therapeutic products derived from genes described above.
Bayer may terminate the research agreement after September 1997 if the
research steering committee, which is comprised of an equal number of
representatives from the Company and Bayer, determines that the research
program is likely to fail to achieve its objectives in all areas and the
parties do not agree on alternative disease targets for the research program.
 
                                      36
<PAGE>
 
  Under the Bayer agreements, the Company will retain the exclusive, worldwide
rights to all diagnostic products and genetic testing services based on the
genes discovered under the research collaboration. The Company will retain the
exclusive, worldwide rights to any therapeutic or diagnostic product for
animal health care. In addition, Bayer has certain registration rights with
respect to the stock it purchased under the agreements as well as certain
Board representation rights.
 
 Eli Lilly and Company
 
  In August 1992, the Company entered into a Research Collaboration and
License Agreement with Lilly and its former subsidiary, Hybritech Incorporated
("Hybritech"), pursuant to which Lilly and Hybritech made an equity investment
in the Company and provided funding over a three-year period to support the
Company's research and development program to discover and sequence the BRCA1
gene. Hybritech was sold by Lilly to Beckman Instruments, Inc. in 1996. The
Company granted to Lilly an exclusive, worldwide license to develop,
manufacture and sell therapeutic products derived from the BRCA1 gene, and
granted to Hybritech an exclusive, worldwide license to develop, manufacture
and sell diagnostic kits derived from the BRCA1 gene. Royalties with respect
to therapeutic and diagnostic products which may in the future be developed by
Lilly and Hybritech will be payable on product sales in each country until the
expiration of the last valid patent covering such products in that country.
Under the agreement, the Company retained the exclusive, worldwide rights to
provide genetic testing services based on the BRCA1 gene.
 
 Hybritech, a subsidiary of Beckman Instruments, Inc.
 
  In March 1993, the Company and Hybritech entered into a related
Collaborative Agreement which establishes certain rights and obligations of
the Company and Hybritech with respect to Hybritech's development and sale of
diagnostic kits. The agreement provides that Hybritech will have access to the
BRCA1 mutation profile developed by the Company for use in connection with
Hybritech's development of diagnostic kits. The agreement gives the Company
the exclusive right to manufacture DNA-or RNA-based reagents for use in
Hybritech's diagnostic kits, should Hybritech elect to develop diagnostic kits
based on such reagents. The agreement also requires Hybritech to make periodic
milestone payments to the Company keyed to progress in the development of a
diagnostic kit. The first of such milestones has been achieved, and Hybritech
has made the related payments.
 
ACADEMIC COLLABORATIONS
 
  The Company has a number of collaborative agreements with the University of
Utah (the "University"), IHC and M.D. Anderson Cancer Center ("MDA") which
represent important elements of the Company's research and development
programs. The Company provides funding for its scientific collaborators at the
University, IHC and MDA to expand the development of databases of families,
the collection of clinical information and the analysis of DNA samples
relating to specific gene discovery projects targeted by the Company. The
University, IHC and MDA have granted the Company an exclusive, worldwide
license to any commercial application including all gene discoveries,
inventions and improvements created or discovered during such research for use
by the Company for diagnostic and therapeutic purposes. The Company's
collaborations with the University's scientists in the field of cancer have
involved sponsorship of several projects at the University's Center for Cancer
Genetic Epidemiology and MDA. The Company has also entered into collaborations
with the University's Cardiovascular Genetics Research Clinic, which focus on
the discovery of genes associated with cardiovascular diseases and obesity.
The Company's collaboration with IHC focuses on the discovery of genes
associated with asthma, osteoperosis and central nervous system disorders. In
addition, the Company has licensed from the University and INSERM in France
certain rights with respect to AGT, an important hypertension gene.
 
  Collaborations Related to Cancer. The Company has entered into a research
agreement and three related exclusive license agreements with the University
in the field of cancer. The Company and the University entered into an
Exclusive License Agreement in October 1991, pursuant to which the Company was
granted an exclusive, worldwide license to the University's patent rights
arising out of the discovery of the BRCA1 breast and ovarian cancer gene for
use in the diagnosis and treatment of breast cancer.
 
                                      37
<PAGE>
 
  In December 1992, the Company entered into a Standard Research Agreement to
provide funding to the Center for Cancer Genetic Epidemiology for research
projects directed to the isolation, sequencing and characterization of genes
predisposing to cancer, including but not limited to colon cancer, lung
cancer, prostate cancer and melanoma. Following the Company's discovery of the
MTS1 gene, the Company entered into an Exclusive License Agreement with the
University in June 1994, pursuant to which the Company was granted an
exclusive, worldwide license to discoveries and inventions arising out of
research at the Center for Cancer Genetic Epidemiology related to germline
mutations of the MTS1 gene and methods of detecting predisposition to cancer
based on the MTS1 gene. In November 1994, the Company entered into a third
Exclusive License Agreement with the University, pursuant to which it was
granted an exclusive, worldwide license to discoveries and inventions arising
out of research at the Center for Cancer Genetic Epidemiology directed to the
localization, sequencing and characterization of the BRCA2 breast cancer
predisposing gene.
 
  In September 1996, the Company entered into a Patent and License Technology
Agreement with the University of Texas and MDA in connection with research
directed to the isolation sequencing and characterization of genes involved in
leukemia, pursuant to which the Company was granted an exclusive, worldwide
license to any commercial application of leukemia genes discovered during such
research.
 
  Collaborations Related to Cardiovascular Disease and Obesity. In May and
August 1995, the Company entered into two Standard Research Agreements with
the University under which the Company reimburses the University for research
performed at its Cardiovascular Genetics Research Clinic on behalf of the
Company in the fields of cardiovascular disease and obesity.
 
  In May and August 1995, the Company also entered into two Exclusive License
Agreements with the University which granted the Company exclusive, worldwide
rights to use the database of families, clinical information and DNA samples
for the discovery of genes for the diagnosis and treatment of cardiovascular
disorders and obesity, subject to certain license fees and royalty payments to
be paid by the Company to the University. The research agreement covering
cardiovascular disorders terminates on April 30, 2000, while the obesity
research agreement terminates on July 31, 2000.
 
  Collaborations Relating to Asthma and Osteoporosis. In September 1995, the
Company entered into a Standard Research Agreement with IHC under which the
Company reimburses IHC for research used to develop a clinical database in the
fields of asthma and osteoporosis by linking IHC's database of patient records
to the Company's genealogy database. IHC will also collect clinical
information and DNA samples on selected patients. The Company and IHC will
jointly own the clinical database, except that IHC may only use the database
for educational and research purposes and to improve health care services to
its patients and may not (i) use the clinical database to discover genes or
develop products from the genes discovered or (ii) sell, license or furnish
access to the database to any other party.
 
  The Company has the exclusive rights to use the clinical database, clinical
information and DNA samples for the discovery of genes and the development of
products for the diagnosis, prevention and treatment of asthma and
osteoporosis. The research agreement covering asthma and osteoporosis
terminates on August 31, 2000.
 
  Collaborations Relating to Central Nervous System ("CNS") Diseases. In June
1996, the Company entered into a Standard Research Agreement with IHC under
which the Company reimburses IHC for research used to develop a clinical
database in the study of CNS disorders, such as attention deficit
hyperactivity disorder, depression, addictive behavior, and obsessive-
compulsive disorders, by linking IHC's database of patient records to the
Company's genealogy database. IHC will also collect clinical information and
DNA samples on selected patients. The Company and IHC will jointly own the
clinical database, except that IHC may only use the database for educational
and research purposes and to improve health care services to its patients and
may not (i) use the clinical database to discover genes or develop products
from the genes discovered or (ii) sell, license or furnish access to the
database to any other party.
 
                                      38
<PAGE>
 
  The Company has the exclusive rights to use the clinical database, clinical
information and DNA samples for the discovery of genes and the development of
products for the diagnosis, prevention and treatment of CNS disorders. The
Company will pay royalties to IHC for diagnostic or therapeutic products or
procedures developed by the Company as a result of the collaboration. The
research agreement covering CNS diseases terminates on April 30, 2001.
 
PATENTS AND PROPRIETARY RIGHTS
 
  The Company intends to seek patent protection in the United States and major
foreign jurisdictions for the genes it discovers, mutations and products of
the genes and related processes, transgenic animals, and other inventions
which it believes are patentable and where the Company believes its interests
would be best served by seeking patent protection. The Company also intends to
seek patent protection or rely upon trade secret rights to protect certain other
technologies which may be used in discovering and characterizing new genes and
which may be used in the development of novel diagnostic and therapeutic
products. To protect its trade secrets and other proprietary information, the
Company requires that its employees and consultants enter into confidentiality
and invention assignment agreements. There can be no assurance as to the
protection that the confidentiality and invention assignment agreements will
afford the Company. In addition, there can be no assurance that any such patents
will issue, or that the breadth or the degree of protection of any claims of
such patents will afford significant protection to the Company.
 
  The Company owns or has licensed rights to one issued patent and 26 patent
applications in the United States and numerous foreign patent applications
relating to genes associated with cancer, hypertension and processes for
identifying and sequencing genes. There can be no assurance, however, that any
patent applications which the Company has filed or will file or to which the
Company has licensed or will license rights will issue or that patents which
do issue will contain commercially valuable claims. In addition, there can be
no assurance that any patents issued to the Company or its licensors will
afford meaningful protection for the Company's technology or products or will
not be subsequently circumvented, invalidated or narrowed.
 
  The Company's processes and potential products may also conflict with
patents which have been or may be granted to competitors, academic
institutions or others. As the biotechnology industry expands and more patents
are issued, the risk increases that the Company's processes and potential
products may give rise to interferences in the U.S. Patent office, or to
claims of patent infringement by other companies, institutions or individuals.
Such entities or persons could bring legal actions against the Company
claiming damages and seeking to enjoin clinical testing, manufacturing and
marketing of the related product or process. If any such actions are
successful, in addition to any potential liability for damages, the Company
could be required to cease the infringing activity or obtain a license in
order to continue to manufacture or market the relevant product or process.
There can be no assurance that the Company would prevail in any such action or
that any license required under any such patent would be made available on
acceptable terms, if at all. Failure by the Company to obtain a license to any
technology that it may require to commercialize its technologies or potential
products could have a material adverse effect on the Company's business,
financial condition and results of operations. There is also considerable
pressure on academic institutions to publish discoveries in the genetic field.
Such a publication by an academic collaborator of the Company prior to the
filing date of the Company's application, if it covers a gene claimed in the
application, may preclude the patent from issuing or the filing of foreign
patent applications, or if a patent was issued, may invalidate the patent.
 
  The Company also relies upon unpatented proprietary technologies, and in the
future may determine in some cases that its interests would be better served
by reliance on trade secrets or confidentiality agreements rather than patents
or licenses. These include the Company's positional cloning, protein
interaction, robotics and bioinformatics technologies. There can be no
assurance that the Company will be able to protect its rights to such
unpatented proprietary technologies or that others will not independently
develop substantially equivalent technologies. If the Company is unable to
obtain strong proprietary rights to its processes or products after obtaining
regulatory clearance, competitors may be able to market competing processes
and products.
 
 
                                      39
<PAGE>
 
  Others may obtain patents having claims which cover aspects of the Company's
products or processes which are necessary for or useful to the development,
use or manufacture of the Company's services or products. In one such
instance, the Company is aware that another group has filed patent
applications having claims to the p16 and p15 proteins and their coding
sequences and to the detection for the risk of cancer by analyzing these
coding sequences. The Company has discovered that the gene for p16 is the MTS1
gene which suppresses tumor growth in many types of cancer. Should such other
group obtain patent protection with respect to its discoveries, the Company's
commercialization of genetic testing services and potential therapeutic
products based on MTS1 or MTS2 could be limited or prohibited. Additionally,
sometimes in similar situations the U.S. Patent Office declares an
interference between competing patent applications. If an interference is
declared, there can be no assurance that the Company would prevail in the
interference. If such other party prevails in the interference, the Company
may be precluded from commercializing services or products based on MTS1 or
MTS2, or may be required to seek a license. There can be no assurance that a
license would be available on commercially acceptable items, if at all.
 
  The Company believes that another group may have filed competing claims for
a portion of the BRCA2 protein and its coding sequence. The Company has
discovered the complete BRCA2 protein and its coding sequence. Should such
other group obtain patent protection with respect to its discoveries or
prevail in any interference, the Company's commercialization of services or
products based on BRCA2 could be limited or prohibited.
 
  In addition, the Company is party to various license agreements which give
it rights to use certain technology in its research, development and testing
processes. There can be no assurance that the Company will be able to continue
to license such technology on commercially reasonable terms, if at all.
Failure by the Company to maintain rights to such technology could have a
material adverse effect on the Company.
 
COMPETITION
 
  Competition in the Company's potential markets is intense. The technologies
for discovering genes which predispose individuals to major diseases and
approaches for commercializing those discoveries are new and rapidly evolving.
Rapid technological developments could result in the Company's potential
services, products, or processes becoming obsolete before the Company recovers
a significant portion of its related research and development costs and
capital expenditures associated therewith. Competitors of the Company in the
United States and abroad are numerous and include, among others, major
pharmaceutical and diagnostic companies, specialized biotechnology firms,
universities and other research institutions, including those receiving
funding from the Human Genome Project. Many of the Company's potential
competitors have considerably greater financial, technical, marketing and
other resources than the Company, which may allow these competitors to
discover important genes in advance of the Company. If the Company does not
discover disease-predisposing genes, characterize their functions, develop
genetic tests and related information services based on such discoveries
obtain regulatory and other approvals, and launch such services or products
before competitors, the Company could be adversely affected. In addition, any
predisposition tests which the Company may develop, including the recently
introduced BRACAnalysis(TM) test, could be made obsolete by less expensive or
more effective tests or methods which may be developed in the future.
The Company expects competition to intensify in the fields in which it is
involved as technical advances in such fields are made and become more widely
known.
 
  Myriad plans to offer genetic testing and information services to detect the
mutation of genes predisposing individuals to major diseases through Myriad
Labs. The clinical laboratory testing business is characterized by intense
competition. There are several large clinical laboratories that market a broad
range of services nationally, and that have substantially larger financial,
marketing, logistical and laboratory resources than Myriad. These companies
typically offer hundreds of different tests and generally compete based on
quality, price and the time required to report results. While only a few of
these laboratories currently provide DNA sequenced testing services, the
Company anticipates that a number of these entities could offer competitive
DNA sequenced testing
 
                                      40
<PAGE>
 
services as technology evolves. The Company is aware of two companies which
already offer a genetic predisposition test for certain mutations of the BRCA1
and BRCA2 genes. In addition, a number of research institutions and university
research centers offer certain genetic predisposition testing on a limited
basis.
 
  The Company is also aware that other companies may be developing DNA probe
kits for genetic risk assessment purposes, some of which may be competitive
with the Company's proposed genetic information business. Companies offering
diagnostic products range from small businesses to large diagnostic, health
care and pharmaceutical companies, many of which have substantially greater
assets and resources than the Company. Several large diagnostic product
companies manufacture test kits and other diagnostic tools that in general are
sold to clinical laboratories.
 
  The Company has licensed to Hybritech the rights to develop, manufacture and
market diagnostic kits for the BRCA1 breast cancer gene. If Hybritech or a
sublicensee is successful in developing a diagnostic kit and receiving FDA
approval for it, Hybritech or such sublicensee could sell the BRCA1 diagnostic
kit to clinical laboratories and other competitors of the Company. Even though
the Company has the right to supply all of the DNA components for such
diagnostic kits and would receive royalties on the sale of all diagnostic kits,
such diagnostic kits, if successfully developed, would likely compete against
the Company's BRCA1 genetic testing business and reduce the Company's market
share and revenues.
 
  The Company also expects to encounter significant competition with respect to
any drugs that may be developed using its technologies. Companies that complete
clinical trials, obtain required regulatory approvals and commence commercial
sales of therapeutic products prior to the Company may achieve a significant
competitive advantage. There can be no assurance, however, that the Company or
its collaborative partners will be able to develop such products successfully
or that such parties will obtain patents covering such products that provide
protection against competitors. Moreover, there can be no assurance that the
Company's competitors will not succeed in developing therapeutic products that
circumvent the Company's products, that such competitors will not succeed in
developing technologies or products that are more effective than those
developed by the Company and its collaborative partners or that would render
technologies or products of the Company and its collaborators less competitive
or obsolete.
 
GOVERNMENT REGULATION
 
  Regulation by governmental authorities in the United States and foreign
countries is a significant factor in the development, manufacture and marketing
of the Company's proposed services and in its ongoing research and development
activities. The Company's genetic testing and information services, as well as
any therapeutic products which may be developed by its collaborative partners,
will require regulatory approval by governmental agencies prior to
commercialization. The establishment and operation of a genetic laboratory
requires regulatory approval and periodic compliance reviews. Various federal
statutes and regulations also govern or influence the testing, manufacturing,
safety, labeling, storage, record keeping and marketing of such products. The
process of obtaining these approvals and the subsequent compliance with
applicable statutes and regulations require the expenditure of substantial time
and financial resources. Any failure by the Company or its collaborators,
licensors or licensees to obtain, or any delay in obtaining, regulatory
approval could have a material adverse effect on the Company's business,
financial condition or results of operations.
 
  Genetic Laboratories. Myriad Labs is subject to government regulation at the
federal, state, and local levels as a clinical laboratory. Myriad Labs has
received CLIA certification from the Department of Health and Human Services
(renewal of which is currently pending but which does not affect the Company's
ability to operate Myriad Labs). On the state level, only New York has
implemented regulations concerning DNA-based diagnostic testing and the Company
has received approval from the State of New York for both BRCA1 and BRCA2
genetic testing. The Company is aware of several other states that require
licensing or registration of clinical laboratory activities. The Company
believes that it has taken all steps required of it in such jurisdictions in
order for Myriad Labs to conduct business in those jurisdictions. However,
there can be no assurance that the Company will be able to maintain state level
regulatory compliance in all states where Myriad Labs may do
 
                                       41
<PAGE>
 
business. Failure to maintain state regulatory compliance, or changes in state
regulatory schemes, could result in a substantial curtailment or even
prohibition of Myriad Lab's clinical activities and could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
  CLIA authorizes the Department of Health and Human Services to regulate
clinical laboratories. These regulations, which affect the Company, mandate
that all clinical laboratories be certified to perform testing on human
specimens and provide specific conditions for certification. These regulations
also contain guidelines for the qualification, responsibilities, training,
working conditions and oversight of clinical laboratory employees. In
addition, specific standards are imposed for each type of test which is
performed in a laboratory. CLIA and the regulations promulgated thereunder are
enforced through quality inspections of test methods, equipment,
instrumentation, materials and supplies on a periodic basis. Any change in
CLIA or these regulations or in the interpretation thereof could have a
material adverse effect on the Company's business, prospects, financial
condition or results of operations.
 
  While the FDA does not currently regulate genetic tests developed by the
Company if used in the Company's own testing laboratory, the FDA has stated
that is has the right to do so, and there can be no assurance that the FDA
will not seek to regulate such tests in the future. In the Federal Register of
March 14, 1996, the FDA proposed to regulate as medical devices the "active
ingredients" (known as "analyte specific reagents" or "ASRs") of certain tests
developed in-house by clinical laboratories. The FDA proposed to classify low
risk devices as class I and exempt them from the premarket notification
requirements of the Food, Drug and Cosmetic Act, and to classify certain "high
risk" ASRs as class III, requiring premarket approval. These "high risk" ASRs
include those intended to diagnose potentially fatal contagious conditions or
to safeguard the blood supply; pending receipt of public comment, ASRs for
human genetic testing are not included within this group. The proposed rule
would also establish labeling requirements for all ASRs and would prohibit the
manufacturer from making any statement regarding analytical or clinical
performance.
 
  Although the proposal does not apply to ASRs used in human genetic testing,
the FDA noted that its Immunology Devices Advisory Panel had recommended that
such ASRs be regulated as class II or class III devices. The FDA stated that
it believes that this recommendation by the panel may be too broad, and
instead sought comments on the degree of regulatory control needed for these
tests. For example, the FDA said that it could regulate as class III devices
"only those ASRs used in tests intended for use in overtly healthy people to
identify a genetic predisposition to a dementing disease, or to a fatal or
potentially fatal medical disorder (e.g., cancers or Alzheimer's disease), in
situations where penetrance is poorly defined or variable and latency is long
(5 years or longer)." The comment period on the proposed rule closed on June
12, 1996. The FDA could issue a final rule at any time, and it is impossible
to know whether or not that final rule will include restrictions on ASRs used
for human genetic testing. If the FDA should require that these tests receive
FDA approval prior to their use in the Company's genetic testing laboratory,
there can be no assurance such approval would be received on a timely basis,
if at all. The failure to receive such approval could require the Company to
develop alternative testing methods or utilize approved ASRs, which could
result in the delay or cessation of such tests. Such a delay or cessation
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
  Therapeutics. Under the Company's current strategic alliances, the Company's
partners have the right to develop therapeutic products based on certain of
the Company's gene discoveries. The Company may also elect to develop
independently therapeutic products based on gene discoveries that it has not
licensed to partners. Such products, including any human gene therapy
products, will be subject to regulation by the FDA and foreign regulatory
authorities and require approval before they may be clinically tested and
commercially marketed for human therapeutic use in the United States and other
countries. The precise regulatory requirements with which the Company and its
corporate partners will have to comply are undergoing frequent revisions and
refinement due to the novelty of the human gene therapies being developed.
Human gene therapy products are a new category of therapeutics, and there can
be no assurance as to the length of the clinical trial period or the number of
patients the FDA will require to be enrolled in the clinical trials in order
to establish the safety, efficacy, and
 
                                      42
<PAGE>
 
potency of human gene therapy products. It is uncertain whether the clinical
data generated in such studies will be acceptable to the FDA such that the FDA
will approve the marketing of such products. In addition, obtaining FDA
approval for therapeutic products is a costly and time consuming process.
 
  The steps required before a pharmaceutical agent may be marketed in the
United States include (a) preclinical laboratory, in vivo and formulation
studies, (b) the submission to FDA of an Investigational New Drug application
("IND"), which must become effective before human clinical trials may
commence, (c) adequate and well-controlled human clinical trials to establish
the safety and efficacy of the drug, (d) the submission of a New Drug
Application ("NDA") to FDA and (e) FDA approval of the NDA, including approval
of all product labeling and advertising. Failure to successfully develop
therapeutic products could have a material adverse effect on the Company's
business, financial results and results of operations.
 
  In addition to the FDA requirements, the NIH has established guidelines
providing that transfers of recombinant DNA into human subjects at NIH
laboratories or with NIH funds must be approved by the NIH Director. The
Director has the authority to approve a procedure only if it is determined
that no significant risk to health or the environment is presented.
 
  The Company's business is also subject to regulation under state and federal
laws regarding environmental protection and hazardous substances control,
including the Occupational Safety and Health Act, the Environmental Protection
Act, and the Toxic Substance Control Act. The Company believes that it is in
material compliance with these and other applicable laws and that its ongoing
compliance therewith will not have a material adverse effect on its business.
There can be no assurance, however, that statutes or regulations applicable to
the Company's business will not be adopted which impose substantial additional
costs to assure compliance or otherwise materially adversely affect the
Company's operations.
 
HUMAN RESOURCES
 
  As of November 1, 1996, Myriad had 181 full-time equivalent employees,
including 28 persons holding doctoral degrees. Most of the Company's employees
are engaged directly in research and development activities. The Company
believes that the success of its business will depend, in part, on its ability
to attract and retain qualified personnel.
 
  The Company's employees are not covered by a collective bargaining
agreement, and the Company considers its relations with its employees to be
good.
 
FACILITIES
 
  The Company's headquarters are located in Salt Lake City, Utah. The Company
currently leases all of its facilities, including a 24,800 square foot
building dedicated to research and development and a 48,500 square foot
building dedicated to administration and laboratory space which has received
federal certification under CLIA to serve as a genetic predisposition testing
laboratory. Additionally, the Company leases 11,500 square feet for various
and support functions. A portion of this space may be sub-leased or abandoned
upon expiration of the lease. Leases are generally for terms of five to ten
years, and usually provide renewal options for terms of up to five additional
years.
 
  The Company believes that its existing facilities and equipment are well
maintained and in good working condition. The Company also believes that the
flexibility to expand its new facilities will provide the Company with
adequate capacity for the foreseeable future. The Company continues to make
investments in capital equipment as needed to meet the requirements of its
collaborative agreements and to meet the anticipated demand for its genetic
predisposition tests.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any legal proceedings.

additional shares of Common Stock at the public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the
same percentage thereof that the number of shares of Common Stock to be
purchased by it shown in the above table bears to 1,700,000 and the Company
will be obligated, pursuant to the option, to sell such shares to the
Underwriters. The Underwriters may exercise such option only to cover over-
allotments made in connection with the sale of Common Stock offered hereby. If

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Article Eighth of the Registrant's Restated Certificate of Incorporation
provides as follows:
 
  "EIGHTH: 1. To the fullest extent permitted by the Delaware General
Corporation Law as the same now exists or may hereafter be amended, the
Corporation shall indemnify, and advance expenses to, its directors, officers
and members of its Scientific Advisory Board and any person who is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, or of a partnership, joint venture, trust or
other enterprise, if such person was or is made a party to or is threatened to
be made a party to or is otherwise involved (including, without limitation, as
a witness) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he is or was a
director or officer of the Corporation or a member of the Corporation's
Scientific Advisory Board or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
or of a partnership, joint venture, trust or other enterprise, including
service with respect to an employee benefit plan; provided, however, that
except with respect to proceedings to enforce rights to indemnification or as
is otherwise required by law, the By-Laws of the Corporation may provide that
the Corporation shall not be required to indemnify, and advance expenses to,
any director, officer or other person in connection with a proceeding (or part
thereof) initiated by such director, officer or other person, unless such
proceeding (or part thereof) was authorized by the Board of Directors of the
Corporation. The Corporation, by action of its Board of Directors, may provide
indemnification or advance expenses to employees and other agents of the
Corporation or other persons only on such terms and conditions and to the
extent determined by the Board of Directors in its sole and absolute
discretion.
 
  2. The indemnification and advancement of expenses provided by, or granted
pursuant to, this Article EIGHTH shall not be deemed exclusive of any other
rights to which a person seeking indemnification or advancement of expenses
may be entitled under any By-Law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.
 
  3. The Corporation shall have the power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent
of the Corporation, or is or was serving at the request of the
 
                                     II-1
<PAGE>
 
Corporation as a director, officer, employee or agent of another corporation,
or of a partnership, joint venture, trust or other enterprise, against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Corporation would have
the power to indemnify him against such liability under this Article EIGHTH.
 
  4. The indemnification and advancement of expenses provided by, or granted
pursuant to, this Article EIGHTH shall, unless otherwise specified when
authorized or ratified, continue as to a person who has ceased to be a
director, officer or member of the Corporation's Scientific Advisory Board and
shall inure to the benefit of the heirs, executors and administrators of such
director, officer or member of the Corporation's Scientific Advisory Board.
The indemnification and rights to advancement of expenses that may have been
provided to an employee or agent of the Corporation by action of the Board of
Directors, pursuant to the last sentence of Paragraph 1 of this Article
EIGHTH, shall, unless otherwise specified when authorized or ratified,
continue as to a person who has ceased to be an employee or agent of the
Corporation and shall inure to the benefit of the heirs, executors and
administrators of such person, after the time such person has ceased to be an
employee or agent of the Corporation, only on such terms and conditions and to
the extent determined by the Board of Directors in its sole discretion. No
repeal or amendment of this Article EIGHTH shall adversely affect any rights
of any person pursuant to this Article EIGHTH which existed at the time of
such repeal or amendment with respect to acts or omissions occurring prior to
such repeal or amendment."
 
  Article V of the Registrant's Restated By-Laws provides as follows:
 
                  "INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 1. Right to Indemnification. Each person who was or is made a party
or is threatened to be made a party to or is otherwise involved (including,
without limitation, as a witness) in any action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that
he is or was a director or an officer of the Corporation or a member of the
Corporation's Scientific Advisory Board or is or was serving at the request of
the Corporation as a director, officer, employee or agent of another
corporation, or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan (hereinafter an
"Indemnitee"), whether the basis of such proceeding is alleged action in an
official capacity as a director, officer, employee or agent or in any other
capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by the Corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than such law permitted the Corporation to provide
prior to such amendment), against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) reasonably incurred or suffered by such Indemnitee in
connection therewith; provided, however, that, except as provided in Section 3
of this Article with respect to proceedings to enforce rights to
indemnification or as otherwise required by law, the Corporation shall not be
required to indemnify or advance expenses to any such Indemnitee in connection
with a proceeding (or part thereof) initiated by such Indemnitee unless such
proceeding (or part thereof) was authorized by the board of directors of the
Corporation.
 
  Section 2. Right to Advancement of Expenses. The right to indemnification
conferred in Section 1 of this Article shall include the right to be paid by
the Corporation the expenses (including attorney's fees) incurred in defending
any such proceeding in advance of its final disposition; provided, however,
that, if the Delaware General Corporation Law requires, an advancement of
expenses incurred by an Indemnitee in his capacity as a director or officer
(and not in any other capacity in which service was or is rendered by such
Indemnitee, including, without limitation, service to an employee benefit
plan) shall be made only upon delivery to the Corporation of an undertaking,
by or on behalf of such Indemnitee, to repay all amounts so advanced if it
shall ultimately be determined by final judicial decision from which there is
no further right to appeal that such Indemnitee is not entitled to be
indemnified for such expenses under this Section 2 or otherwise. The rights to
 
                                     II-2
<PAGE>
 
indemnification and to the advancement of expenses conferred in Sections 1 and
2 of this Article shall be contract rights and such rights shall continue as
to an Indemnitee who has ceased to be a director, officer, employee or agent
and shall inure to the benefit of the Indemnitee's heirs, executors and
administrators. Any repeal or modification of any of the provisions of this
Article shall not adversely affect any right or protection of an Indemnitee
existing at the time of such repeal or modification.
 
  Section 3. Right of Indemnitees to Bring Suit. If a claim under Section 1 or
2 of this Article is not paid in full by the Corporation within sixty (60)
days after a written claim has been received by the Corporation, except in the
case of a claim for an advancement of expenses, in which case the applicable
period shall be twenty (20) days, the Indemnitee may at any time thereafter
bring suit against the Corporation to recover the unpaid amount of the claim.
If successful in whole or in part in any such suit, or in a suit brought by
the Corporation to recover an advancement of expenses pursuant to the terms of
an undertaking, the Indemnitee shall also be entitled to be paid the expenses
of prosecuting or defending such suit. In (i) any suit brought by the
Indemnitee to enforce a right to indemnification hereunder (but not in a suit
brought by the Indemnitee to enforce a right to an advancement of expenses) it
shall be a defense that, and (ii) in any suit brought by the Corporation to
recover an advancement of expenses pursuant to the terms of an undertaking,
the Corporation shall be entitled to recover such expenses upon a final
adjudication that, the Indemnitee has not met any applicable standard for
indemnification set forth in the Delaware General Corporation Law. Neither the
failure of the Corporation (including its board of directors, independent
legal counsel, or its stockholders) to have made a determination prior to the
commencement of such suit that indemnification of the Indemnitee is proper in
the circumstances because the Indemnitee has met the applicable standard of
conduct set forth in the Delaware General Corporation Law, nor an actual
determination by the Corporation (including its board of directors,
independent legal counsel, or its stockholders) that the Indemnitee has not
met such applicable standard of conduct, shall create a presumption that the
Indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the Indemnitee, be a defense to such suit. In any suit
brought by the Indemnitee to enforce a right to indemnification or to an
advancement of expenses hereunder, or brought by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the burden of
proving that the Indemnitee is not entitled to be indemnified, or to such
advancement of expenses, under this Article or otherwise shall be on the
Corporation.
 
  Section 4. Non-Exclusivity of Rights. The rights to indemnification and to
the advancement of expenses conferred in this Article shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, the Corporation's Certificate of Incorporation as amended from time
to time, these by-laws, any agreement, any vote of stockholders or
disinterested directors or otherwise.
 
  Section 5. Insurance. The Corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such
expense, liability or loss under the Delaware General Corporation Law.
 
  Section 6. Indemnification of Employees and Agents of the Corporation. The
Corporation may, to the extent authorized from time to time by the Board of
Directors, grant rights to indemnification and to the advancement of expenses
to any employee or agent of the Corporation to the fullest extent of the
provisions of this Article with respect to the indemnification and advancement
of expenses of directors and officers of the Corporation and members of the
Corporation's Scientific Advisory Board."
 
                       Other Indemnification Provisions
 
  The Registrant has obtained insurance which insures the officers and
directors of the Registrant against certain losses and which insures the
Registrant against certain of its obligations to indemnify such officers and
directors.

ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to Directors, Officers and controlling persons of the
Registrant pursuant to the provisions described under "Item 15--
Indemnification of Officers and Directors" above, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a Director, Officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such Director, Officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be
a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  The undersigned Registrant hereby undertakes that:
 
  (1) For the purposes of determining any liability under the Securities Act,
the information omitted from the form of prospectus filed as part of this
registration in reliance upon Rule 430A and contained in a form of prospectus
filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the
Securities Act shall be deemed to be part of this registration statement as of
the time it was declared effective.
 
  (2) For the purposes of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial bona fide offering thereof.

                                   AGREEMENT
                                   ---------

     This Agreement is made by and between Roche Molecular Systems, Inc.
("Roche"), a Delaware corporation, and Myriad Genetics, Inc. ("MGI"), Salt Lake
City, Utah, hereafter collectively refereed to as "The Parties".

                                   BACKGROUND
                                   ----------

A.    Roche has the right to grant immunities from suit under certain United
States Patents describing and claiming, inter alia a gene amplification process
                                        ----- ----
known as the polymerase chain reaction ("PCR") technology.

B.  MGI has attained substantial expertise in validating, documenting and
performing sophisticated diagnostic procedures.

C.  MGI desires to obtain an immunity from suit from Roche to practice PCR
Technology to perform human in vitro clinical laboratory services, and Roche is
                            -- -----
willing to grant such an immunity, on the terms and subject to the conditions
provided exclusively in this Agreement.

     NOW, THEREFORE, for and in consideration of the mutual covenants contained
herein, Roche and MGI agree as follows:

     1.   Definitions
          -----------

          For the purpose of this Agreement, and solely for that purpose, the
terms set forth hereinafter shall be defined as follows:

                                       1
<PAGE>
 
          1.1  The term "Affiliate" of a designated party to this Agreement
shall mean:

                a)  an organization of which fifty percent (50%) or more of the
                    voting stock is controlled or owned directly or indirectly
                    by either party to this Agreement;

                b)  an organization which directly or indirectly owns or
                    controls fifty percent (50%) or more of the voting stock of
                    either party to this Agreement;

                c)  an organization, the majority ownership of which is directly
                    or indirectly common to the majority ownership of either
                    party to this Agreement; and

                d)  an organization under (a), (b), or (c) above in which the
                    amount of said ownership is less than fifty percent (50%)
                    and that amount is the maximum amount permitted pursuant to
                    the law governing the ownership of said organization.

It is understood and agreed, however, that the term "Affiliate" shall not
include Genentech Inc., a company located at 460 Point San Bruno Boulevard,
South San Francisco, California, U.S.A. ("Genentech").

          1.2  "Assay" shall mean an in vitro diagnostic procedure utilizing PCR
                                     -- -----
Technology to detect the presence, absence or quantity of a nucleic acid
sequence associated with a specific human disease or condition.

                                       2
<PAGE>
 
          1.3  "Diagnostic Product" shall mean an assemblage of reagents,
including but not limited to reagents packaged in the form of a kit, useful in
performing an Assay.

          1.4  "Effective Date" shall mean the date on which the last signatory
to this Agreement signs the Agreement.

          1.5  "Licensed Field" shall mean the field of human in vitro
                                                              -- -----
diagnostics solely for the detection of genetic diseases, genetic pre-
disposition to disease, microorganisms associated with infectious diseases,
cancer, or for tissue transplant typing or Parentage.

          1.6  "Licensed Services" shall mean the performance of an Assay by MGI
to detect nucleic acid sequences associated with a human disease or condition
within the Licensed Field. Licensed Services include but are not limited to, any
combination of the steps of collecting a sample for analysis, isolating nucleic
acid sequences therein, amplifying one or more desired sequences, analyzing the
amplified material and reporting the results.

          1.7  "Licensed Technology" shall mean the application of PCR
Technology, as that term is defined in section 1.10, to perform Licensed
Services.

          1.8  "Net Service Revenues" shall mean gross invoice price for the
Licensed Services performed by MGI (or the fair market value for any nonmonetary
consideration which MGI agrees to receive in exchange for Licensed Services),
less the following deductions where they are factually applicable and are not
already reflected in the gross invoice price:

                                       3
<PAGE>
 
                (i)  discounts allowed and taken, in amounts customary in the
                     trade (which shall include the difference between the
                     dollar amount charged by MGI for a Licensed Service and the
                     Medicare and/or Medicaid Limits of Allowance and/or
                     reimbursement limitations of a Third Party insurance
                     program); and

                (ii) sales and/or use taxes and/or duties imposed upon and with
                     specific reference to particular sales.

          No allowance or deduction shall be made for commissions or
collections, by whatever name known.

          It is hereby understood and agreed that, to the extent feasible, the
Licensed Services shall at all times be invoiced, listed and billed by MGI as a
separate item in MGI's invoices, bills and reports to customers. However, in
the event a Licensed Service is offered in combination with another non-PCR
diagnostic assay(s) or together with a non-testing service(s) (e.g., an
interpretive or consultive service) as part of a package (e.g., genetic
counseling) (this combination of a Licensed Service with a non-testing or
interpretive service is hereinafter referred to as a "Combination Service"),
then Net Service Revenues for purposes of determining royalties on a Licensed
Service which is part of a Combination Service shall be determined by
multiplying the gross invoice price, less applicable deductions, for the
Combination Service, by the appropriate fraction in Attachment I hereto. The
fraction specified in Attachment I for a particular Licensed Service shall be
mutually agreed to by The Parties as accurately reflecting the value contributed
by the Licensed Service to the overall value of the package of the Combination
Service as offered by MGI.

                                       4
<PAGE>
 
          The Net Service Revenues of the Licensed Services that are performed
by MGI for any person, firm or corporation controlling, controlled by, or under
common control with MGI, or enjoying a special course of dealing with MGI, shall
be determined by reference to the Net Service Revenues which would be applicable
under this Section in an arm's length transaction by MGI to a Third Party other
than such person, firm or corporation.

          1.9  "Parentage" shall mean analysis of human genetic material to
ascertain whether two or more individuals are biologically related, but
specifically excludes analysis of forensic evidence for a criminal proceeding.

          1.10  "PCR Technology" shall mean polymerase chain reaction technology
covered by United States Patent Nos. B1 4,683,195 and B1 4,683,202 and any
reissue or reexamination patents thereof.

          1.11  "Third Party" shall mean a party other than an Affiliate of The
Parties to this Agreement.

     2.   Grant
          -----

2.1  Upon the terms and subject to the conditions of this Agreement, Roche
hereby grants to MGI, and MGI hereby accepts from Roche, a royalty-bearing, non-
exclusive immunity from suit under PCR Technology solely to use Licensed
Technology to perform Licensed Services within the United States and its
possessions and the Commonwealth of Puerto Rico. The Parties understand and
agree that no rights are hereby granted, expressly or by implication, under U.S.
Patent No. 4,965,188 (the '188 patent). An immunity from suit under the '188
patent may be obtained by purchase

                                       5
<PAGE>
 
of Roche-manufactured polymerase or by contacting the Director of Licensing,
Roche Molecular Systems, Inc., 1145 Atlantic Avenue, Alameda, CA 94501
(510/865-5400).

          2.2  The Licensed Technology hereunder may be practiced solely for the
performance of Licensed Services and for no other purpose whatsoever, and no
other right, immunity or license is granted expressly, impliedly or by estoppel.

          2.3  MGI expressly acknowledges and agrees that the immunity from suit
pursuant to this Agreement is personal to MGI alone and MGI shall have no right
to sublicense, assign or otherwise transfer or share its rights under the
foregoing immunity from suit and further agrees that Licensed Services will be
performed, offered, marketed and sold only by MGI and MGI shall not authorize
any other party, including Affiliates, to practice the Licensed Technology, nor
shall it practice the Licensed Technology in conjunction with any other party.

          2.4  For each Combination Service that MGI offers pursuant to this
immunity from suit, MGI agrees that it will notify Roche at least sixty (60)
days before it commercializes said Combination Service. The Parties shall then
agree on the fraction of the value of Combination Services which is attributable
to the Licensed Service component. As to all other Licensed Services offered by
MGI which are not part of a Combination Service, MGI agrees to keep Roche
informed about the availability from MGI of each such Service within a
reasonable time after MGI commences offering the Service.

          2.5  Roche hereby grants to MGI the right and MGI accepts and agrees
to credit Roche as the source of PCR Technology rights in MGI's, promotional
materials and any other materials intended for distribution to Third Parties as
follows:

                                       6
<PAGE>
 
    "This test is performed pursuant to an agreement with Roche Molecular
    Systems, Inc."

    3.  Acknowledgement and Agreement on Diagnostic Products
        ----------------------------------------------------

          3.1  MGI acknowledges and agrees that the immunity granted hereunder
is for the performance of Licensed Services only and does not include any right
to make, have made, offer or sell any products, including devices, PCR reagents,
kits or Diagnostic Products. MGI further acknowledges and agrees that Roche
Affiliates are in the business of providing clinical laboratory testing services
and the commercial sale of diagnostic testing systems and therefore may compete
directly with MGI's business.

    4.  Royalties, Records and Reports
        ------------------------------

          4.1  Royalties. For the rights and privileges granted under this
               ----------
Agreement, MGI shall pay to Roche earned royalties equal to fifteen percent
(15%) of MGI's Net Service Revenues for each Assay performed.

          4.2  MGI shall keep full, true and accurate books of account
containing all particulars which may be necessary for the purpose of showing the
amount payable to Roche by way of royalty or by way of any other provision under
this Agreement. Such books and the supporting data shall be open at all
reasonable times, for three (3) years following the end of the calendar year to
which they pertain (and access shall not be denied thereafter, if reasonably
available), to the inspection of Roche or an independent certified public
accountant retained by Roche for the purpose of verifying MGI's royalty
statements or MGI's compliance in other respects with this Agreement. If in
dispute, such records shall be kept until the dispute is settled. The inspection

                                       7
<PAGE>
 
of records shall be at Roche's sole cost and expense, unless the inspector
concludes that royalties reported by MGI for the period being audited are
understated by five percent (5%) or more from actual royalties, in which case
the costs and expenses of such inspection shall be paid by MGI.

          4.3  MGI shall within thirty (30) days after the first day of January,
April, July and October of each year deliver to Roche a true and accurate
royalty report.  This report shall give such particulars of the business
conducted by MGI during the preceding three (3) calendar months as are pertinent
to an accounting for royalty under this Agreement and shall include at least the
following:

                (i)    the number of tests performed in connection with
                       performance of the Licensed Services and Combination
                       Services during those three (3) months;

                (ii)   compilation of billings thereon and the allowable
                       deductions therefrom;

                (iii)  Net Service Revenues and the calculation of total
                       royalties thereon; and

                (iv)   the calculation of the net royalty payable to Roche. If
                       no royalties are due, it shall be so reported.

          The correctness and completeness of each such report shall be attested
to in writing by the responsible financial officer of MGI's organization or by
MGI's external auditor or by the chairman or other head of MGI's internal audit
committee.

                                       8
<PAGE>
 
          Simultaneously with the delivery of each such report, MGI shall pay to
Roche the royalty and any other payments due under this Agreement for the period
covered by such report. All payments due Roche hereunder shall be sent together
with the royalty report by the due date to the following address:

                     Roche Molecular Systems, Inc.
                     P.O. Box 18139
                     Newark, NJ. 07191

or to any address that Roche may advise in writing.

          4.4    All amounts payable hereunder by MGI to Roche shall be payable
in United States currency.

          4.5  MGI's obligation to pay royalties pursuant to this Agreement
shall terminate upon a final holding of invalidity or unenforceability of all of
the patents identified in Section 1.10, supra, by a court of appellate
                                        -----
jurisdiction or by a trial court from which no appeal is or can be taken.

          4.6  If MGI shall fail to pay any amount specified under this
Agreement after the due date thereof, the amount owed shall bear interest at the
Citibank NA base lending rate ("prime rate") plus 2% from the due date until
paid, provided, however, that if this interest rate is held to be unenforceable
for any reason, the interest rate shall be the maximum rate allowed by law at
the time the payment is due.

     5.   Performance of Licensed Services
          --------------------------------

          5.1  The Parties agree that quality assurance is of utmost importance
in the performance of Licensed Services. To that end, MGI agrees that it will:

                                       9
<PAGE>
 
                (a)  participate in at least one independent proficiency testing
                     program for each Licensed Service when such program(s)
                     becomes available; and

                (b)  comply with all Medicare, Medicaid and/or CLIA standards
                     for diagnostic testing as well as all other applicable
                     federal, state and local regulations applicable to human
                     diagnostic testing.

    6.  Technology Notification
        -----------------------

          6.1  With respect to any invention, improvement or discovery
(hereinafter referred to as "Discoveries" in this Article) of MGI made after
entering into this Agreement, resulting from work conducted under this Agreement
and being applicable to PCR, if MGI decides to license that Discovery to Third
Parties, then MGI agrees to provide to Roche, unless not possible due to MGI's
previous commitments to Third Parties relating to said Discoveries, a reasonable
opportunity to negotiate a license to use said Discoveries in PCR-based
diagnostic products and services. Such Discoveries include, but are not limited
to, improvements of the PCR process or in the performance of Assays,
modifications to or new methods of performing the Assays, including the
automation of the PCR process or of the Assays.

          6.2  Any agreement reached between The Parties as a result of MGI's
notification to Roche of a Discovery pursuant to Section 6.1 hereto shall be

Effective Date or (b) the date of expiration of the last to expire of the
patents included within the PCR Technology, which patent contains at least one
claim covering the performance of Licensed Services. At the end of the five year
term, this Agreement is renewable upon the same terms and conditions, for
successive one (1) year periods unless either party notifies the other in
writing within one hundred and twenty (120) days of the end of each one year
period of its intent to terminate the Agreement. Termination pursuant to such
notice shall be effective at the end of said one hundred and twenty (120) day
notice period.

          8.2  If in the course of performing and offering Licensed Services,
MGI fails to comply with the quality assurance provisions of Article 5, MGI
shall so notify Roche and Roche shall notify MGI to correct the defects. MGI
shall have thirty (30) days from receipt of such notice to cure all defects of
which it is notified. If MGI does not cure all such defects within the
designated thirty (30) days, Roche may then in its sole discretion terminate
this Agreement in its entirety, or any portion thereof immediately. For the
purposes of this Section and this Agreement, MGI's failure to

                                       11
<PAGE>
 
provide an accurate and correct test result when participating in an independent
proficiency testing program pursuant to Section 5.1 (a), on two consecutive
evaluations, shall automatically be deemed a failure to comply with Article 5
and shall be a material breach of this Agreement.

          8.3  Notwithstanding any other Section of this Agreement, MGI may
terminate this Agreement for any reason on thirty (30) days' written notice to
Roche.

          8.4  The decision of a Court or Administrative body finding Roche
liable or culpable due to MGI's performance of Licensed Services shall give
Roche the right to terminate this Agreement immediately upon notification to
Roche of said decision.

          8.5 The immunity granted hereunder to MGI shall automatically
terminate upon (i) an adjudication of MGI as bankrupt or insolvent, or MGI's
admission in writing of its inability to pay its obligations as they mature;
(ii) or an assignment by MGI for the benefit of creditors; (iii) or MGI's
applying for or consenting to the appointment of a receiver, trustee or similar
officer for any substantial part of its property; (iv) such receiver, trustee or
similar officers appointment without the application or consent of MGI, if such
appointment shall continue undischarged for a period of ninety (90) days; or
MGI's instituting (by petition, application, answer, consent or otherwise) any
bankruptcy, insolvency arrangement, or similar proceeding relating to MGI under
the laws of any jurisdiction; (v) or the institution of any such proceeding (by
petition, application or otherwise) against MGI, if such proceeding shall remain
undismissed for a period of ninety (90) days or the issuance or levy of any
judgment, writ, warrant of attachment or execution or similar process against a
substantial part of the property of MGI, if such judgment, writ, or similar
process shall not be released, vacated or fully bonded within ninety (90) days
after its issue or levy; (vi) loss of MGI's

                                       12
<PAGE>
 
federal or state licenses permits or accreditation necessary for operation of
MGI as a healthcare institution.

          8.6  Roche shall have the right to terminate this Agreement by written
notice to MGI upon any change in the ownership or control of MGI or of its
assets. Termination under this Section shall be effective immediately upon
receipt by MGI of Roche's notice of termination. For such purposes, a "change in
ownership or control" shall mean that 30% or more of the voting stock of MGI
become subject to the control of a person or entity, or any related group of
persons or entities acting in concert, which person(s) or entity(ies) did not
control such proportion of voting stock as of the effective date of the
Agreement. Analogously, Roche shall have the right to terminate this Agreement
upon any transfer or sale of 30% or more of the assets of MGI to another party.

          8.7  Breach. Upon any breach of or default of a material term under
               -------
this Agreement by MGI, Roche may terminate this Agreement upon thirty (30) days'
written notice to MGI. Said notice shall become effective at the end of the
thirty-day (30) period, unless during said period MGI fully cures such breach or
default to Roche's reasonable satisfaction and notifies Roche of such a cure.

          8.8  Upon termination of this Agreement as provided herein, all
immunities and rights granted to MGI hereunder shall revert to or be retained by
Roche. To the extent Roche has licensed technology or know-how of MGI pursuant
to Article 6 hereto, those licenses shall remain in force according to their
terms.

          8.9  MGI's obligations to report to Roche and to pay royalties to
Roche as to the Licensed Services performed under the Agreement prior to
termination or expiration of the Agreement shall survive such termination or
expiration.

    9.  Confidentiality - Publicity
        ---------------------------

          9.1  Except as otherwise specifically provided in Section 2.5, MGI
agrees to obtain Roche's approval before distributing any written information,
including but not limited to promotional and sales materials, to Third Parties
which contains references to Roche or this Agreement. Roche's approval shall not
be unreasonably withheld or delayed and, in any event, Roche's decision shall be
rendered within three (3) weeks of receipt of the written information. Once
approved, such materials, or abstracts of such materials, which do not
materially alter the context of the material originally approved may be
reprinted during the term of the Agreement without further approval by Roche
unless Roche has notified MGI in writing of its decision to withdraw permission
for such use.

          9.2  Each Party agrees that any financial, legal or business
information or any technical information disclosed to it (the "Receiving Party")
by the other (the "Disclosing Party") in connection with this Agreement shall be
considered confidential and proprietary and the Receiving Party shall not
disclose same to any Third Party and shall hold it in confidence for a period of
five (5) years and will not use it other than as permitted under this Agreement
provided, however, that any information, know-how or data which is orally
disclosed to the Receiving Party shall not be considered confidential and
proprietary unless such oral disclosure is reduced to writing and given to the
Receiving Party in written form within thirty (30) days after oral disclosure
thereof. Such confidential and proprietary information shall include, without
limitation, marketing and sales information, commercialization plans and
strategies, research and development work plans, and technical information such
as patent applications, inventions, trade secrets, systems, methods, apparatus,
designs, tangible material, organisms and products and derivatives thereof.

                                       14
<PAGE>
 
          9.3  The above obligations of confidentiality shall not be applicable
to the extent:

                a)  such information is general public knowledge or, after
                    disclosure hereunder, becomes general or public knowledge
                    through no fault of the Receiving Party; or

                b)  such information can be shown by the Receiving Party by its
                    written records to have been in its possession prior to
                    receipt thereof hereunder; or

                c)  such information is received by the Receiving Party from any
                    Third Party for use or disclosure by the Receiving Party
                    without any obligation to the Disclosing Party provided,
                    however, that information received by the Receiving Party
                    from any Third Party funded by the Disclosing Party (e.g.
                    consultants, subcontractors, etc.) shall not be released
                    from confidentiality under this exception; or

                d)  the disclosure of such information is reasonably needed for
                    use in connection with performing, offering and selling
                    Licensed Services; or

                e)  the disclosure of such information is required or desirable
                    to comply with or fulfill governmental requirements,
                    submissions to governmental bodies, or the securing of
                    regulatory approvals.

                                       15
<PAGE>
 
          9.4  With the exception of Section 2.5, each party shall, to the
extent reasonably practicable, maintain the confidentiality of the provisions of
this Agreement and shall refrain from making any public announcement or
disclosure of the terms of this Agreement without the prior consent of the other
party, except to the extent a party concludes in good faith that such disclosure
is required under applicable law or regulations, in which case the other party
shall be notified in advance.

     10.  Compliance
          ----------

          In exercising any and all rights and in performing its obligations
hereunder, MGI shall comply fully with any and all applicable laws, regulations
and ordinances and shall obtain and keep in effect licenses, permits and other
governmental approvals, whether at the federal, state or local levels, necessary
or appropriate to carry on its activities hereunder. MGI further agrees to
refrain from any activities that would have an adverse effect on the business
reputation of Roche. Roche will advise MGI of any such activities and MGI will
have thirty (30) days to correct such activity.

     11.  Assignment
          ----------

          This Agreement shall not be assigned by MGI (including without
limitation any purported assignment or transfer that would arise from a sale or
transfer of MGI's business). Roche may assign all or any part of its rights and
obligations under this Agreement at any time without the consent of MGI. MGI
agrees to execute such further acknowledgments or other instruments as Roche may
reasonably request in connection with such assignment.

     12.  Negation of Warranties and Indemnity
          ------------------------------------

     12.1  Nothing in this Agreement shall be construed as:

          (a)   a warranty or representation by Roche as to the validity or
                scope of any Licensed Technology;

          (b)   a warranty or representation that the practice of the Licensed
                Technology is or will be free from infringement of patents of
                Third Parties (however, Roche is not aware of any such
                infringement and no such claim has been made);

          (c)   an obligation to bring or prosecute actions or suits against
                Third Parties for infringement;

          (d)   except as expressly set forth herein, conferring the right to
                use in advertising, publicity or otherwise any trademark, trade
                name, or names, or any contraction, abbreviation, simulation or
                adaptation thereof, of Roche;

          (e)   conferring by implication, estoppel or otherwise any license,
                right or immunity under any patents or patent applications of
                Roche other than those specified in PCR Technology, regardless
                of whether such patents and patent applications are dominant or
                subordinate to those in PCR Technology;

          (f)   an obligation to furnish any know-how not provided in PCR
                Technology; or

                                       17
<PAGE>
 
                (g)   creating any agency, partnership, joint venture or similar
                      relationship between Roche and MGI.

          12.2  ROCHE MAKES NO EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE.

          12.3  MGI acknowledges that the technology licensed hereby is newly
developed, and agrees to take all reasonable precautions to prevent death,
personal injury, illness and property damage from the use of such technology.
MGI shall assume full responsibility for its use of the Licensed Technology and
shall defend, indemnify and hold Roche harmless from and against all liability,
demands, damages, expenses (including attorneys' fees) and losses for death,
personal injury, illness, property damage or any other injury or damage,
including any damages or expenses arising in connection with state or federal
regulatory action, in view of the use by MGI, including its officers, directors,
agents and employees, of the Licensed Technology, except that MGI shall not be
liable to Roche for injury or damage arising solely because of Roche's
negligence.

          12.4 Roche warrants and represents that is has the right and power to
grant this immunity from suit to MGI and that the granting of such immunity does
not require the consent or approval of a Third Party. Roche does hereby place
MGI on notice, however, that the Eastman Kodak Company ("Kodak") has asserted
certain interests in PCR Technology, which assertions are the subject of an
arbitration proceeding between Kodak, Roche and the Cetus Corporation (now part
of Chiron). Roche believes that any claims Kodak has asserted or may assert, as
would impact this Agreement, are without merit. However, The Parties expressly
agree that Roche will not be held responsible or liable in any way to MGI in the
event that Kodak is found to have certain rights in PCR Technology that may
impact this Agreement or the rights granted hereunder, except that Roche agrees
to refund to MGI that portion of the

                                       18
<PAGE>
 
royalties actually paid to Roche by MGI under this Agreement which portion of
the royalties is held by a final decree in the above-mentioned arbitration to
belong to Kodak. In no event shall Roche's refund to MGI exceed the total
royalties MGI already paid to Roche.

                (a)  The arbitration tribunal shall consist of three

                 RIDER CONCERNING SUPPLEMENTAL PATENT RIGHTS TO
                         DIAGNOSTIC SERVICES AGREEMENT

The purpose of this rider is to set forth the agreement of Myriad Genetics, Inc.
("MGI") and Roche Molecular Systems, Inc. ("RMS") concerning the supplemental
rights to additional patents relating to PCR technology which RMS offers and the
parties agree to add to the rights granted to MGI by the Agreement between the
parties, dated April 23, 1993 (the "Diagnostic Services Agreement").

1.   It is understood by the parties that RMS may, from time to time, come into
     possession or control of additional patents or claims of patents relating
     to PCR technology rights to which RMS may decide to offer to add to the
     Diagnostic Services Agreement and which MGI may desire to accept.
     Accordingly, appended hereto as APPENDIX A is a list of such additional
     patents or claims of patents as RMS is currently offering to which MGI, by
     its authorized representative, has indicated its acceptance thereof in
     accordance with the rights of use and all other pertinent obligations,
     restrictions and limitations as set forth in the Diagnostic Services
     Agreement.

2.   APPENDIX A may be amended by mutual agreement of the parties in writing so
     as to add additional patent rights being offered by RMS. Accordingly, a new
     APPENDIX A signed and dated by both parties shall supersede any prior
     APPENDIX A and shall become a part of this rider.

3.   It is expressly understood and agreed by the parties that the grant of
     additional patent rights herein does not in any way otherwise modify the
     Diagnostic Services Agreement and that all provisions of that Agreement
     shall remain in full

RIDER CONCERNING SUPPLEMENTAL PATENT RIGHTS TO
DIAGNOSTIC SERVICES AGREEMENT (Cont'd.)


     force and effect as originally set forth therein. The term of the
     Diagnostic Services Agreement shall control the enjoyment of rights
     hereunder and is not extended by the rights granted hereby nor shall there
     be any additional royalty obligation to RMS beyond that set forth in said
     Agreement.

4.   In consideration of the further rights being granted it hereunder, MGI
     agrees to remain in good faith compliance with the applicable terms of the
     Diagnostic Services Agreement, including reporting and payment of royalties
     and the limitation on use of PCR technology strictly for the performance of
     licensed services and not to make products.

5.   In the event that MGI's obligation to pay royalties under the Diagnostic
     Services Agreement for its rights to use the PCR technology shall cease for
     any reason, whether by termination, expiry, invalidation or otherwise, then
     the parties agree that this rider shall become null and void and the rights
     granted hereunder terminated without notice and the parties shall be free
     to negotiate a new agreement with respect to the patent rights listed on
     APPENDIX A.

 Re:  Proposed Change in Royalty Reporting for License Agreement dated April 23,
      1993, between Roche Molecular Systems, Inc. ("RMS"), Licensor, and Myriad
      Genetics, Inc. (MGI"), Licensee

 RMS is pleased to offer Myriad Genetics, Inc. an opportunity to simplify the
 royalty reporting requirements of the above-referenced Agreement between RMS
 and MGI (the "Agreement"). Under the Agreement, MGI must submit quarterly
 royalty reports. This letter is to offer MGI the option of converting to a
 biannual schedule of royalty reporting. If you accept this option, instead of
 having to provide detailed reports every three months, within 30 days, you will
 report only once every six months, within 60 days. Royalty payments due will be
 submitted, as usual, along with the royalty report. We believe that initiating
 this new reporting schedule will alleviate our licensees' administrative
 burdens.

 If you choose to have this change apply to the Agreement, the terms of Article
 4, Section 4.3 will be amended as follows:

    MGI shall within sixty (60) days after the first day of January and July of
    each year deliver to RMS a true and accurate royalty report. Such report
    shall cover the preceding six (6) calendar months; and shall be submitted
    either i) on the "Summary Royalty Report", a copy of which is attached
    hereto as Attachment II, or ii) on a form generated by MGI which duplicates
    the format of the Summary Royalty Report; and shall include at least the
    following:

 To indicate MGI's acceptance of this amendment to the Agreement, please have an
 authorized representative of MGI sign both duplicate originals of this letter.
 You should retain one fully executed original and return the other, within
 forty-five (45) days to: Kathe Kiehn, Licensing Manager, at the address shown
 above. This will effectively amend the Agreement as of the date of your
 signature. If we have not received the executed letter within 45 days of the
 date written above, this offer shall be deemed withdrawn, and MGI shall
 continue to report on a quarterly basis, within 30 days.

 If you have any questions, you may telephone Ms. Kiehn at (510) 814-2970 or
 Beverly Dynes, Licensing Coordinator, at (510) 814-2976.

 Sincerely,
 ROCHE MOLECULAR SYSTEMS, INC.       MYRIAD GENETICS, INC.

Re:  Agreement effective April 23, 1993 between Roche Molecular Systems, Inc. 
     and Myriad Genetics, Inc. covering PCR-based human diagnostic services

Dear Mr. Moyse:

This is in response to your inquiry about alternative royalty options to those 
presently contained in Myriad's Agreement.

The percent royalty owed on net sales revenues under the above-referenced 
Agreement may be lowered by the up-front payment of annual minimum royalties, 
which are fully creditable against royalties earned in the ensuing twelve-month 
period. An annual minimum payment is due within thirty (30) days of January 1st 
for each calendar year in which Myriad wishes to participate in this program.

The following schedule details the amounts of such annual minimum up-front 
payments and the resulting royalty rates.

            PERCENT ROYALTY RATE AS A FUNCTION OF UP-FRONT PAYMENT
            ------------------------------------------------------

                 Annual Minimum               
                Up-Front Payment               Royalty Rate 
                ----------------               ------------
                      0                            15%
                   $ 50,000                        13%
                   $150,000                        11%
                   $250,000                         9%

Please call me with any questions you may have about the implementation of this 
program.

Sincerely,
ROCHE MOLECULAR SYSTEMS, INC.
