ITEM 1.       DESCRIPTION OF BUSINESS

         This Annual Report contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Forward-looking statements may be found
throughout this Annual Report, particularly under "Business" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations." Such
forward-looking statements are indicated by the use of such words as "intends,"
"expects," "may," "anticipates," "estimates," "desires," "believes" and similar
expressions. Actual results may differ from those described by forward-looking
statements as a result of many risks and uncertainties, including, but not
limited to, those described under "Factors Affecting Future Performance."
Prospective investors are advised not to rely upon forward-looking statements,
but rather base their investment decision on the Company's actual results to
date.

GENERAL DESCRIPTION

         The Company provides genetic susceptibility testing services for common
diseases that are treatable and preventable. To date, the Company has focused on
four diseases: periodontitis (gum disease), osteoporosis (bone disease),
coronary artery disease (heart disease) and diabetic retinopathy (blindness
associated with diabetes). The Company's tests identify genetic markers which,
if present in a patient, increase the probability that such patient will be
affected by the disease or that the disease will progress more rapidly and
become more severe. Doctors and dentists will use the Company's genetic
susceptibility tests to assess the risk involved for individual patients and to
adopt appropriate treatments or therapy, including preventive measures. The
Company's genetic tests allow early determination of genetic predisposition to
these four diseases with the following potential benefits:

         (1) Patients with genetic predisposition to a disease may adopt health
care and lifestyle changes that will delay or prevent onset of the disease or
reduce disease severity;

         (2) Early detection of genetic predisposition will allow doctors and
dentists to select the most appropriate (i) preventive strategy where no disease
symptoms are present or (ii) course of treatment once the patient develops the
disease; and

         (3) Earlier and better treatment selection will motivate patients and
improve outcomes.

         The Company's tests assist doctors in the development of better
preventive treatment strategies, aid patients in making more informed decisions,
and help payers to target healthcare investments where they make the biggest
difference. The Company believes that this will contribute to a better quality
of life, while directing healthcare resources to individuals who derive the
greatest benefit. Accordingly, the Company's mission is to improve patient care
and treatment outcomes by incorporating genetic information regarding disease
susceptibility into overall risk assessment and treatment planning.

PRODUCTS AND SERVICES

GENETIC SUSCEPTIBILITY TEST FOR PERIODONTAL DISEASE.

         The Company's first genetic susceptibility test detects a genetic
susceptibility to severe gum disease (periodontitis). Periodontitis is a
bacterially-induced chronic inflammation that destroys the collagen fibers and
bone that surround and support the teeth. Untreated, periodontitis will
eventually result in tooth loss.

         The Company's periodontal susceptibility test is the result of a
scientific breakthrough in which an association was discovered between a
specific IL-1 genotype and severe periodontal disease. IL-1 is a cytokine or
protein that is known to play a role in inflammation and the expression of
periodontal disease. Patients with this specific genotype have been found to
progress more rapidly towards severe periodontal disease. It has also been
determined that cells with this genotype produce as much as four times more IL-1
in response to the same bacterial challenge. Prevention or therapeutic

                                        1


<PAGE>

intervention aimed at reducing the bacterial challenge should decrease the
stimulus for IL-1 production and thereby protect the patient against the
potentially destructive effects of this genotype. It is estimated that
approximately 30% of the population will test positive for this genotype.

         The Company has developed its periodontal susceptibility test and
continues to be governed by a project agreement between the Company and
Sheffield University. In November, 1997, a patent related to the detection of
genetic predisposition to periodontal disease was issued to the Company from
Sheffield University, Dr. Gordon Duff and Dr. Kenneth Kornman. The Company
commercially launched its periodontal susceptibility test on October 3, 1997.

GENETIC SUSCEPTIBILITY TEST FOR OSTEOPOROSIS.

         The Company's second genetic test is a test for susceptibility to
osteoporosis. Osteoporosis, the most common bone disease, resulting in a
decrease in the amount of normal bone which leaves the affected individual more
susceptible to fractures. The Company has identified a genetic marker that in
clinical trials was associated with a more severe loss of bone through
osteoporosis. The osteoporosis susceptibility test is a genetic test capable of
indicating a greater susceptibility to severe osteoporosis in postmenopausal
women. This susceptibility appears to involve a more rapid loss of bone as
estrogen levels decrease and menopause occurs.

         The Company has completed three clinical trials of the osteoporosis
susceptibility test. The first trial focused on the relationship of the genetic
test to bone-mineral density ("BMD") in post-menopausal women with a history of
bone fractures. All three trials confirmed the association between the specific
genetic marker and the onset of osteoporosis.

         The Company's test provides data that will allow practitioners to
practice preventive medicine. Results of this test will assist women who are
approaching menopause in deciding whether to start treatment. On introduction
into the marketplace, this test will be targeted at all women in their
mid-thirties, the point in their lives when the estrogen level begins to
decrease. This will enable counseling at a sufficiently early stage in the
process that significant bone loss can be avoided through lifestyle modification
and/or drug/hormone therapy.

         In December, 1997, a patent related to the method of testing for
genetic predisposition to osteoporosis was awarded to Sheffield University.
Sheffield University, has in turn, granted to the Company an exclusive worldwide
license to utilize the underlying patent. Under the terms of the Company's
Project Agreement with Sheffield University, upon the Company's
commercialization of the osteoporosis susceptibility test, Sheffield University
is obligated to assign the patent to the Company in its entirety.

GENETIC SUSCEPTIBILITY TEST FOR CORONARY ARTERY DISEASE (Patent Pending).

         The Company's third genetic susceptibility test, which is currently
under development, is the coronary artery disease test (the "CAD test"). The CAD
test is a genetic test capable of detecting those individuals with a
significantly higher level of susceptibility to coronary artery disease.

         The availability of the Company's CAD test will provide practitioners
with a means of truly practicing preventive medicine with respect to coronary
artery disease. The CAD test can be given to all individuals early in life
because genetic risk factors do not change over time. Individuals who test
positive for the genotype can be treated with more aggressive approaches to risk
factor reduction. As these individual age, they can be provided with more
regular: (i) monitoring of cholesterol levels; (ii) blood pressure testing; and
(iii) early intervention to alter the level of blood lipids (I.E., fats). Such
an approach allows for truly preventive medicine through early risk factor
reduction and appropriate monitoring for early detection of any problems.

         A patent application related to the method of testing for genetic
predisposition to coronary artery disease has been filed and assigned to the
Sheffield University. Sheffield University, has in turn, granted to the Company

                                        2


<PAGE>

an exclusive worldwide license to utilize the underlying patent. Under the terms
of the Company's Project Agreement with Sheffield University, upon its
commercialization of the CAD test, Sheffield University is obligated to assign
the patent to the Company in its entirety.

GENETIC SUSCEPTIBILITY TEST FOR RETINOPATHY IN DIABETICS (Patent Pending).

         The Company's fourth genetic susceptibility test, which is currently
being developed, is a test to determine the susceptibility to sight-threatening
retinopathy in diabetics. This susceptibility involves a continued and increased
risk of losing vision when an individual has been diagnosed with diabetes.

         The Company has identified a genetic marker that is correlated with an
increased risk of developing diabetic retinopathy in patients who have diabetes.
This correlation seems to indicate an earlier onset of retinopathy in patients
who have diabetes thus putting such individuals at risk of losing their sight at
an earlier age. The availability of such a test would allow practitioners to
assess a patient's risk of losing his or her sight due to diabetes at the time
that he or she is diagnosed with the disease. Preventive treatment would allow
doctors to practice truly preventive medicine, providing a means of identifying
susceptible patients early in the disease process. Enhanced assessment and
monitoring can then be initiated from the start, allowing early detection of
problems and preemptive treatment that will ultimately reduce the incidence of
diabetes related vision loss. This would translate into improvements in patient
quality of life and cost savings.

         A patent application related to the method of testing for the genetic
predisposition to retinopathy in patients with diabetes has been filed and
assigned to Sheffield University. Sheffield University, in turn, has granted the
Company an exclusive, worldwide license to utilize the underlying patent. Under
the terms of the Company's Project Agreement with Sheffield University, upon its
commercialization of the diabetic retinopathy susceptibility test, Sheffield
University is obligated to assign the patent to the Company in its entirety.

TESTING PROCEDURE

         Each of the Company's four genetic susceptibility tests requires, or
will require, that a single procedure be utilized. To conduct a genetic
susceptibility test, the doctor draws a blood sample and submits it to the
Company's customer service department. The customer service department then logs
in the sample and submits sample batches to the testing laboratory. The
laboratory then performs the test following the Company's specific protocol and
informs the Company of the results. The Company, in turn, advises the doctor of
the results, who informs the patient and determines the appropriate course of
action. At the time results are provided to the doctor, the Company's billing
service (which the Company presently "outsources") will invoice the patient
directly for the test. The doctor will then invoice the patient for his or her
professional services related to administration of the test.

         The Company will continue to use one or more sophisticated, certified,
and fully validated laboratories capable of providing consistent and high
quality analysis. Customer service is handled via the Company's toll free "888"
numbers by the Company's own staff who are knowledgeable about its genetic
susceptibility tests, the procedural requirements of the testing system and the
related diseases.

PRE-MARKETING TRIALS/STATUS OF SUSCEPTIBILITY TESTS

         As an internal procedural standard, the Company conducts three
categories of clinical trials in conjunction with its genetic susceptibility
tests. The first trial is called a proof of principle trial, used to prove a
laboratory finding. The results of this trial are utilized to support the
initial patent application and therefore need to be completed before the patent
application can be filed. The second trial is a confirmatory trial. The purpose
of the confirmatory trial is to independently confirm the results of the proof
of principle trial. The third category of trial relates to clinical utility. The
clinical utility trial is conducted to learn what is the most effective
utilization of the test in actual clinical practice.

                                        3


<PAGE>

         Following confirmatory studies, additional trials are completed on
larger populations to help develop broad scientific evidence supporting the
clinical utility of each of the Company's tests. Such additional trials not only
strengthen the support for each tests' known use (I.E., detecting genetic
susceptibility) but also lead to additional practical uses of the susceptibility
tests (E.G., use of the susceptibility tests to determine a patient's
responsiveness to a given drug).

PRODUCT DEVELOPMENT

         Beyond its current four genetic susceptibility tests, the Company has
on-going research to continue to identify other genetic markers that appear to
be associated with certain other common diseases. The Company plans on filing
additional patent applications to cover these discoveries. It is the Company's
intent to bring these discoveries to market in the form of additional genetic
susceptibility tests. The Company has also come upon certain genetic markers
that might be likely candidates to serve as therapeutic targets, those
susceptible to influence by drug agents. The Company is considering certain
collaborative long term relationships with pharmaceutical companies as a method
to provide for either the licensing of its discoveries or to assist in the
research and development of future products.

         There may be additional applications of either the Company's testing
services or the underlying technology that the Company uses to develop and
support its genetic testing services. The Company will seek to exploit
opportunities to develop such additional applications in conjunction with other
companies so long as the Company's focus remains on genetic susceptibility
testing. The Company granted a worldwide, nonexclusive, nontransferable license
to Digisphere, LLC to market customized versions of its computer modeling
technology to pharmaceutical companies. Previously, the Company had only used
its computer modeling technology for the internal development of its genetic
testing services. On August 1, 1997, Digisphere, LLC was formed, representing a
joint venture between the Company and Nelson Communications Inc. ("NCI"), one of
the largest providers of health care marketing services to pharmaceutical
companies in the United States. Ownership of Digisphere, LLC is divided
approximately equally between the Company and NCI. Digisphere, LLC has a stated
term which lasts until August 31, 2000, unless extended. However, the
arrangement may be terminated upon mutual agreement or if certain performance
goals are not met. The primary purpose of the joint venture is to market the
Company's computer modeling technology to pharmaceutical companies as a tool
which provides medical education regarding disease progression. A secondary
purpose of the joint venture is to provide marketing information to those
patients who test positive on one of the Company's tests and who subsequently
send in a business reply card seeking more information. In both aspects of the
joint venture, the Company will be acting as the technology/information partner
and NCI will be functioning as the marketing partner. As of December 31, 1997,
the Company has not received any revenues from this joint venture.

MARKET AND SELLING STRATEGIES

         GENERAL STRATEGY. The Company's strategy is to build a commercial
operation based on the delivery of its genetic susceptibility testing services
on a worldwide basis. The Company's testing services aim at multi-factorial
diseases which are treatable and preventable. The Company's strategy assumes
that genetic tests revealing susceptibility to preventable diseases will
ultimately be highly valued by the public, by clinicians involved in prevention
and treatment planning, by industries involved in clinical trials and by
healthcare payers and administrators who need to direct limited resources where
they will make the biggest difference.

         The Company utilizes a sales and marketing approach which aims to
improve patient care and treatment outcomes by incorporating genetic information
regarding disease susceptibility into overall risk assessment and treatment
planning. The Company hopes to accomplish this through educating doctors,
managed care organizations, industry and the public about the value of targeting
healthcare investments based on an individual's tendency to develop a specific
disease. The Company seeks to influence attitudes and mindsets through clearly
articulating the benefit for its customers and adopting a missionary sales
approach in partnership with crusaders in the field. Emphasis is placed on
building strong relationships with key decision-makers and educators who will
work with the Company to overcome the obstacles and influence the acceptance of
genetic testing, especially testing that reveals wanted information, as part of
the medical standard of care.

                                        4


<PAGE>

         The Company's initial goals are to establish genetic tests such as its
periodontal susceptibility test into overall risk assessment and treatment
planning for patients. Ultimately, the Company envisions these tests being used
more broadly by healthcare administrators and practitioners as a screening tool
to direct limited resources in a more targeted and proactive way.

SELLING METHODS

         DIRECT SALES. The Company plans to build demand for its susceptibility
tests using a small direct consultative sales organization specializing in
genetic testing, risk assessment and change of behavior. The Company does not
plan on building a large sales force capability in any specific market; however,
when the need for additional sales force activity increases within a particular
segment, the Company will consider "co-marketing" or other business arrangements
with companies with a large sales organization in the field. The Company's
direct sales capability will focus on the profession segment initially, then
shift to institutional and large buying group sales. After a sales partner has
been brought on, the Company will focus on sales partner support and
trade/professional association meetings. The Company will thereafter continue to
seek to establish corporate partnerships which will produce revenues,
credibility and a market presence for its other services and products.

         PROFESSIONAL AND INDUSTRY MEETINGS/TRADE ASSOCIATIONS. Currently, the
Company is present and markets its products and services at all national and
selected regional associations and meetings where a genetic susceptibility test
has applicability to the professionals in attendance. Over time, the Company
anticipates its partners playing an increasingly important role in the specific
disease markets where its tests are used.

INTELLECTUAL PROPERTY

         The Company's commercial success will be dependent in part on its
ability to obtain patent protection on genes, genetic sequences and/or their
relationship to common diseases, or products or methods based on the association
between particular genes and diseases, discovered by the Company and Sheffield
University. The Company has a total of three issued patents and 11 patent
applications pending. Of the three previously issued patents, two relate to the
Company's genetic tests and one relates to the Company's computer technology.
The U.S. Patent and Trademark Office has issued patents for the Company's
periodontal and osteoporosis tests in November and December, 1997, respectively.
Of the 11 patent applications pending, nine relate to the Company's anticipated
genetic tests, and two relate to computer technology.

         The Company has filed and will continue to file foreign counterparts of
its U.S. applications within the appropriate time frames. Where the Company has
originally filed in another country, it plans to file U.S. and other foreign
counterparts within the appropriate time frame. These applications seek to
protect these gene markers and corresponding use of gene markers, and products
derived therefrom and uses therefor. Some of these applications also identify
possible biological functions for the genes and gene fragments based in part on
a comparison to genes or gene fragments included in public databases but do not
contain any laboratory or clinical data with respect to such biological
functions.

         The Company owns the patent application covering the genetic marker
related to its periodontal susceptibility test. However, with each of the other
tests, the Section of Molecular Medicine at Sheffield University holds the
patent application but has granted the Company an exclusive worldwide,
irrevocable, transferable license to make, have made, use, offer to sell,
license and otherwise transfer products created under the applicable patents.
Sheffield University has retained the right to carry on internal research
related to the underlying patents. However, under the terms of the Company's
Project Agreements with Sheffield University, upon the commercialization of each
test, Sheffield University is obligated to assign the patent to the Company in
its entirety.

         The Company is continuing to identify and develop applications related
to additional genetic markers. The Company has also applied for trademark
protection for the name of its periodontal susceptibility test. The Company's
proprietary technology is subject to numerous risks. See "Factors Affecting
Future Performance."

ETHICAL, LEGAL AND SOCIAL IMPLICATIONS OF GENETIC SUSCEPTIBILITY TESTING

         The prospect of broadly available genetic susceptibility 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. The recent movement towards discovery and
commercialization of susceptibility tests for screening a person's likelihood of
developing one or more chronic conditions has also focused public and
legislative attention on the need to protect the privacy of genetic screening
medical information. With the progression towards more comprehensive record
keeping by health insurers and managed care firms, this need has led to a number
of legal initiatives. The recently enacted federal health insurance reform law
(The Health Insurance Portability and Accountability Act of 1996) recognizes the
comparability of information obtained by genetic means to other types of
personal medical information. The law prohibits insurance companies from
refusing health insurance coverage to individuals on the basis of their medical
history, including "genetic information." This legislation also prohibits
employees from discrimination in hiring practices on the same basis. This should
serve as an example of a trend to protect the privacy of patients, while
allowing them to be screened for conditions which, as medicine progresses, can
be prevented, reduced in severity, or cured. Although the current trend is
pro-genetic testing, governmental authorities could, for social or other
purposes, limit the use of genetic testing or prohibit testing for genetic
susceptibility to certain conditions.

         The Company has attempted to take a proactive stance in the ethical
arena. The Company has engaged Dr. Philip Reilly, who is both an M.D. (board
certified specialist in clinical genetics) and an attorney to advise the Company
in the area of genetic testing and its ethical, legal and clinical utility
ramifications. Additionally, the Company is currently advising doctors who
administer its genetic susceptibility tests to take special efforts to maintain
the confidentiality of the test results. The Company's intent is to avoid
information about test results being disclosed to insurers until issues
regarding insurability have been fully analyzed and acted upon by the
appropriate legislative bodies.

         On August 1, 1997, the Company formed a joint venture named Digisphere,
LLC whose purpose, in part, will be to provide marketing information to those
patients who test positive on one of the Company's tests and who subsequently
send in a business reply card seeking more information. The confidentiality of
patient information is subject to regulation by state law. A variety of statutes
and regulations exist safeguarding privacy and regulating the disclosure and use
of medical information. State constitutions may provide privacy rights and
states may provide private causes of action for violations of an individual's
"expectation of privacy." Tort liability may result from unauthorized access and
breaches of patient confidence. The Company intends to comply with state law and
regulations governing medical information privacy.

COMPETITION

         Although testing for major genetic defects, such as Down's Syndrome,
has been available for years, genetic susceptibility testing for multi-factorial
diseases is a newly emerging growth segment. Despite this segment's relatively
young age, other companies do exist which have research programs seeking disease
related genes for therapeutic and susceptibility testing purposes, including
some that involve treatable/ preventable disease. Other companies with research
programs include OncorMed, Inc. ("OncorMed"), Myriad Genetics, Inc. ("Myriad")
and Genome Therapeutics Corp. ("GTC"). GTC has announced that it has research
programs focusing on osteoporosis. Myriad has a test for breast cancer and has
announced research programs for osteoporosis and coronary artery disease.
OncorMed, while engaged in the development of genetic susceptibility tests, is
focused solely on cancer.

         Additionally, some of the Company's competitors receive data and
funding from the Human Genome Project. The Human Genome Program is a federally
funded program focused on sequencing the human DNA and enriching the sequence
data with information about its biological function. To the extent the Company's
competitors receive data and funding from the Human Genome Project at no cost to
them, they may have a competitive advantage over the Company.

                                        6


<PAGE>

         Each of the above noted company's involvement with genetic
susceptibility testing, together with large market capitalizations as public
companies, validates this newly emerging market. In the case of newly introduced
products requiring "change of behavior," (such as genetic susceptibility tests)
multiple competitors may accelerate market acceptance and penetration through
increasing awareness. Moreover, two different genetic susceptibility tests for
the same disease may in fact test or measure different components, and thus
actually be complementary when given in parallel as an overall assessment of
risk, rather than being competitive with each other.

         Furthermore, with the exception of OncorMed, the primary focus of each
of the above-referenced companies is performing gene-identifying research for
pharmaceutical companies for therapeutic purposes, with genetic susceptibility
testing being a secondary goal. On the other hand, the Company's primary
business focus is developing and commercializing genetic susceptibility tests
for common diseases, with only an ancillary drug discovery program.

GOVERNMENT REGULATION

         The sampling of blood, saliva or cheek scrapings from patients and
subsequent analysis in a clinical laboratory does not, at the present time,
require Federal Drug Administration ("FDA") or regulatory authority approval
inside the U.S. for either the sampling procedure or the analysis itself. The
samples are taken in the healthcare provider's office, using standard materials
previously approved as medical devices, such as sterile lancets and swabs. The
testing procedure itself is performed in one or more registered, certified
clinical laboratories under the auspices of the Clinical Laboratory Improvement
Amendments of 1988 ("CLIA"), administered by the Health Care Financing
Administration. The federal regulations governing approval of the laboratory
facilities and applicable state and local regulations governing the operation of
clinical laboratories would also apply. Changes in such regulatory schemes could
require advance regulatory approval of genetic susceptibility tests sometime in
the future could have a material adverse effect on the Company's business.
Certain practices of the Company may require it, or a subsidiary, to be licensed
and regulated under CLIA.

         In addition, while the Company's main focus is on genetic
susceptibility testing, the Company may, in the future, endeavor to partner with
pharmaceutical companies in the area of drug development. Any drug products
developed by the Company or the Company's future collaborative partners, prior
to marketing in the United States, would be required to undergo an extensive
regulatory approval process by the FDA. 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 and its collaborative partners' activities,
diminish any competitive advantages that the Company or its collaborative
partners may attain and adversely affect its ability to receive royalties. Once
regulatory approval of a 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. The discovery of previously unknown problems
with a product or manufacturer may result in restrictions on such product or
manufacturer. Such restriction could include withdrawal of the product from the
market.

EMPLOYEES

         As of March 1, 1998, the Company had 44 full-time employees. Of the
Company's employees, 84% are engaged directly in the development and
commercialization of tests and 16% are engaged in administrative or managerial
activities.

         The Company's employees are not covered by a collective bargaining
agreement, and the Company considers its relations with its employees to be
good.

FACTORS AFFECTING FUTURE PERFORMANCE

         UNCERTAINTY OF MARKET ACCEPTANCE FOR GENETIC SUSCEPTIBILITY TESTS

         The commercial success of the Company's genetic susceptibility tests
and those that it may develop will depend upon their acceptance as medically
useful and cost-effective by patients, physicians, dentists, other members of
the medical and dental community and insurers. Broad market acceptance can be
achieved only with substantial education about the benefits and limitations of
such tests. The Company expects to expend substantial financial resources to
effectively promote the benefits of its genetic susceptibility tests and those
that it may develop. The Company intends to expend significant resources on
educating medical and dental caregivers, policymakers, patients, insurers and
others. It is uncertain whether current genetic susceptibility tests or others
that the Company may develop will gain market acceptance on a timely basis. If
patients, dentists and physicians do not accept the Company's tests, or take a
longer time to accept than the Company anticipates, then the Company's revenues
and profit margins may be reduced and may result in losses.

         NEW BUSINESS VENTURE

         The securities being offered by the Company are subject to the risks
inherent in any new business venture. Although the Company has operated as a
contract research firm since 1986, it have limited experience and a short
history of operations with respect to marketing and selling susceptibility tests
or therapeutics. The Company has had only minimal revenues related to the sale
of its genetic susceptibility testing services. With the exception of its
periodontal susceptibility test, the genetic susceptibility tests anticipated to
be sold by the Company have not yet been finally designed, developed, tested or
marketed. Therefore, there can be no assurance that the Company will be able to
complete these genetic susceptibility tests, that those tests will be accepted
in the marketplace, or that the tests can be sold at a profit. The Company's
business may also be affected significantly by economic and market conditions
over which the Company has no control. Consequently, an investment in the
Company's Common Stock is highly speculative. The Company does not guarantee any
return on an investment in its Common Stock.

         DIFFICULTY OF DEVELOPING GENETIC SUSCEPTIBILITY TESTS

         It is uncertain whether the Company will be successful in developing
and bringing to market its current portfolio or future tests based on the
genetic discoveries made by the Company and its collaborators. Even when the
Company discovers a genetic marker (I.E., a genetic variation or polymorphism
associated with increased disease incidence or severity), additional clinical
trials need to be conducted to confirm the initial scientific discovery and to
support the scientific discovery's clinical utility in the marketplace. The
results of a clinical trial could delay, reduce the test's acceptance or cause
the Company to cancel a program. Such delays, reduced acceptance or
cancellations would reduce revenues and may result in losses.

         UNCERTAINTY OF INSURANCE REIMBURSEMENT

         The Company's ability to successfully commercialize existing genetic
susceptibility tests and others that the Company may develop depends in part on
obtaining adequate reimbursement for such testing services and related
treatments from government and private health care insurers (including health
maintenance organizations) and other third-party payors. Physicians' and 

                                        8


<PAGE>

dentists' decisions to recommend genetic susceptibility tests, as well as
patients' elections to pursue testing, are likely to be heavily influenced by
the scope and extent of reimbursement 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 testing and treatment 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 insurers or third-party payors have agreed
to reimburse patients for genetic susceptibility tests. As a result, the Company
initially expects to bill patients directly for the genetic susceptibility
tests.

         It remains uncertain whether insurers or third-party payors will elect
to provide full reimbursement coverage for the genetic susceptibility tests in
the near future. If adequate reimbursement coverage is not available from
insurers or third-party payors, it is uncertain whether individuals will elect
to directly pay for the test. If both insurers or third-party payors and
individuals are unwilling to pay for the test, then the number of tests
performed will be significantly decreased. Such a scenario would result in
reduced revenues and possible losses.

         RELIANCE ON COLLABORATIVE PARTNERS

         In 1994 the Company entered into a strategic alliance with the Section
of Molecular Medicine at Sheffield University, a world leader in the genetic
aspects of common diseases with an inflammatory component. In 1996 the Company
formalized its relationship by entering into an exclusive worldwide agreement
(the "Master Agreement"). Under the terms of the Master Agreement, the Company
will undertake the development and commercialization of any discoveries
resulting from the research of Section of Molecular Medicine at Sheffield
University. In exchange, Sheffield University will receive a share of the
resultant net profits, with the percentage of net profits for the Company and
Sheffield University agreed upon separately under project agreements related to
each test (each a "Project Agreement"). The Company's share of the net profits
under such Project Agreements ranges from 50% to 67%. The Master Agreement may
be terminated with or without cause by either party upon six-months notice.
Although termination does not affect any existing Project Agreements, any
termination would limit or eliminate the Company's access to future Sheffield
University genetic discoveries that fall outside of the scope of the Company's
existing Project Agreements.

         The Project Agreements (excluding the agreement covering the
periodontal test which has no fixed termination date) each have a ten-year term,
commencing in September 1996, which is automatically renewed for one-year
periods unless terminated by either party upon a six month's prior notice. The
Project Agreements may be terminated: (i) by mutual agreement, (ii) by either
party 30 days after an uncured breach or default by the other party; (iii) by
either party upon certain events of bankruptcy; and (iv) by the Company if
Professor Gordon Duff ceases to be an employee of, or head of the Section of
Molecular Medicine at Sheffield University. In the case of mutual agreement to
terminate, or in the case of the Company terminating a Project Agreement prior
to the end of the ten-year term, net profits would be reallocated by mutual
agreement in light of the continued responsibilities between the parties.
However, Sheffield University's share of the net profits would not be allowed to
fall below ten percent (10%) in such an instance. If the Master Agreement or any
of the Project Agreements were terminated, the Company would need to enter into
additional collaborative arrangements in order to continue to build a future
pipeline of products.

         In the future the Company may, in order to facilitate the sale of the
Company's testing services and/or products, enter into collaborative selling
arrangements with one or more other persons. It is uncertain whether the Company
will be able to negotiate acceptable collaborative arrangements in the future or
that such collaborative arrangements will be successful. If the Company is
unable to identify collaborative partners to sell certain of its services and/or
products, the Company may be forced to develop an internal sales force to market
and sell its services and/or products in markets where it is not intending on
developing a direct selling presence. Such a process would take more time and
potentially cost more. As a result, the Company's revenues and earnings would be
reduced. If the Company does enter into collaborative selling arrangements, its
success will depend upon the efforts of others and may be beyond the Company's
control. Failure of any collaborative selling arrangement could result in
reduced revenues and possible losses.

         UNCERTAIN ABILITY TO PROTECT PROPRIETARY TECHNOLOGY

         The Company's success will partly depend on its ability to obtain
patent protection, both in the United States and in other countries, for its
products and services. In addition, the Company's success will also depend upon
its ability to preserve its trade secrets and to operate without infringing the
proprietary rights of third parties.

         The Company has eleven (11) patent applications pending, including
applications covering certain of its anticipated genetic susceptibility tests.
There can be no assurance that the Company's patent applications will ever be
issued as patents or that the claims of any issued patents will afford
meaningful protection for the Company's technology or products. Further, others
may develop similar products which test for susceptibility related to some
diseases yet avoid infringing upon, or conflicting with, the Company's
anticipated patents. In addition, there can be no assurance that any patents
issued to the Company will not be challenged, and subsequently narrowed,
invalidated or circumvented.

         The Company's testing services and/or 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
Patent and Trademark Office, 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. It is uncertain
whether 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, results of operations and
cash flows. In addition, there is considerable pressure on academic institutions
and other entities to publish discoveries in the genetic field. Such a
publication by an academic institution or other entity, prior to the Company's
filing of a patent application on such discovery, may compromise the Company's
ability to obtain U.S. and foreign patent protection for the discovery.

         The Company also relies upon unpatented proprietary technologies. The
Company relies on confidentiality agreements with its employees, consultants and
collaborative partners to protect such proprietary technology. 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.

         The United States Patent and Trademark Office issued new Utility
Guidelines in July 1995 that address the requirements for demonstrating utility,
particularly in inventions relating to human therapeutics. While the guidelines
do not require clinical efficacy data for issuance of patents for human
therapeutics, there can be no assurance that the Patent and Trademark Office's
interpretations of such guidelines, and any chances to such interpretations will
not delay or adversely affect the Company's or the Company's collaborators'
ability to obtain patent protection. The biotechnology patent situation outside
the United States is even more uncertain and is currently undergoing review and
revision in many countries.

         TECHNOLOGICAL CHANGES RESULTING IN PRODUCT OBSOLESCENCE

         Market acceptance and sales of the Company's testing services could
also be adversely affected by technological change. It is uncertain whether the
Company's competitors will succeed in developing genetic susceptibility tests
that circumvent or are more effective than the Company's technologies or
services. Further, it is uncertain whether such developments would render the
Company's or the Company's collaborators' technology or services less
competitive or obsolete. Further, the Company's testing services could be
rendered obsolete as a result of future innovations in the treatment of gum
disease, osteoporosis, coronary artery disease or diabetes retinopathy, which
could have a significant negative impact on the Company's ability to market its
services effectively.

         POSSIBLE FAILURE TO MAINTAIN EXCHANGE LISTINGS ON THE NASDAQ SMALLCAP
         MARKET(SM) OR THE BOSTON STOCK EXCHANGE

         The Company is currently listed on The Nasdaq SmallCap Market(SM) and
the Boston Stock Exchange. If the Company is unable to satisfy and maintain the
requirements for continued listing on The Nasdaq SmallCap Market(SM) or the
Boston Stock Exchange, its shares will not be traded in those markets.

         If the Company's shares were delisted from the above exchanges,
trading, if any, would be conducted in the over-the-counter market in the
so-called "pink sheets" or the OTC Bulletin Board, which was established for
securities that do not meet The Nasdaq SmallCap Market(SM) listing requirements.
Consequently, selling the Company's shares would be more difficult because
smaller quantities of shares could be bought and sold, transactions could be
delayed, and security analysts' and news media's coverage of the Company may be
reduced. These factors could result in lower prices and larger spreads in the
bid and ask prices for the Company's shares.

         RISKS OF LOW-PRICED SHARES

         If the Company's shares were delisted from The Nasdaq SmallCap
Market(SM) and/or the Boston Stock Exchange, they may become subject to Rule
15g-9 under the Exchange Act. That rule imposes additional sales practice
requirements on broker-dealers that sell low-priced securities to persons other
than established customers and institutional accredited investors. For
transactions covered by this rule, a broker-dealer must make a special
suitability determination for the purchaser and have received the purchaser's
written consent to the transaction prior to sale. Consequently, the rule may
affect the ability of broker-dealers to sell the Company's shares and affect the
ability of holders to sell its shares in the secondary market.

         The SEC's regulations define a "penny stock" to be any equity security
that has a market price less than $5.00 per share or with an exercise price of
less than $5.00 per share, subject to certain exceptions. The penny stock
restrictions will not apply to the Company's shares if they are listed on The
Nasdaq SmallCap Market(SM) or the Boston Stock Exchange and the Company provides
certain price and volume information on a current and continuing basis, or meet
required minimum net tangible assets or average revenue criteria. The Company
cannot assure you that its shares will qualify for exemption from these
restrictions. If the Company's shares were subject to the penny stock rules, the
market liquidity for the shares could be adversely affected.

ITEM 6.       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS

OVERVIEW

         Since inception, the Company has devoted substantially all of its
resources to maintaining its research and development programs and supporting
contract research agreements. To date, the Company has received limited revenues
from the sale of its periodontal susceptibility test. Revenues received by the
Company have historically been payments pursuant to contract research
agreements. For the fiscal year ended December 31, 1997, the Company had a net
loss of $4,494,062 and as of December 31, 1997 had an accumulated deficit of
$5,365,310.

         The Company could 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 the Company's genetic susceptibility 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 last fiscal year
to the beta testing and validation of its genetic susceptibility test related to
periodontitis, as well as building its sales and marketing force in preparation
for the commercial launch of the periodontal susceptibility test. Additional
outlays have been expended on the hiring of additional customer service 

                                       13


<PAGE>

personnel and the associated increase in use of test materials and commercial
laboratory charges. The Company also incurred increased development expenses
during the year related to work on developing its genetic susceptibility tests
for osteoporosis, coronary artery disease and diabetic retinopathy. The Company
expects research and development expenses to continue to increase as personnel
and research and development facilities are expanded.

         Selling, general and administrative expenses for the year ended
December 31, 1997 increased $1,705,289 from the year ended December 31, 1996.
The increase was attributable to additional expenses as a result of the Company
becoming a publicly-traded entity. The Company recently commercially launched
its periodontal susceptibility test on October 3, 1997. Additionally, the
Company expects that its general and administrative expenses will continue to
increase in support of its research and development efforts and the anticipated
growth of its genetic susceptibility testing business.

RESULTS OF OPERATIONS

         YEAR ENDED DECEMBER 31, 1997 AND 1996.

         Revenues for the year ended December 31, 1997 decreased by $1,722,591,
from $1,918,879 for the year ended December 31, 1996 to $195,928 for the same
period in 1997, due to the decrease in contract research agreements. In the
summer of 1996, the Company changed its focus from providing pharmaceutical
companies clinical trial and research services pursuant to contract research
agreements to concentrating its resources on developing genetic susceptibility
tests. This change in focus resulted in a significant decrease in revenue for
the year ended December 31, 1997 compared to the same period for 1996. Research
and development expenses increased by $265,219 to $1,223,468 for the year ended
December 31, 1997 from $958,249 for the same period in 1996. The research and
development expenses are attributed to development expenses related to work on
developing its genetic susceptibility tests for periodontitis, osteoporosis,
coronary artery disease and diabetic retinopathy. The increase in research and
development is due to its focus on developing genetic susceptibility tests.
Selling, general and administrative expenses increased by $1,705,289 from
$1,162,768 for the year ended December 31, 1996 to $2,868,057 for the same
period in 1997. The increase in 1997 was primarily due to the hiring of
additional sales and marketing personnel and costs related to the pre-commercial
launch of its periodontal susceptibility test, sales and marketing expenses
related to the launch of the periodontal susceptibility test and salaries and
benefits paid to existing and newly-hired sales and marketing employees. In
addition, the Company has incurred additional expenses as a result of it being a
publicly-traded entity.

         Interest income for the year ended December 31, 1997 increased by
$45,328 primarily due to the investment of unexpended public offering proceeds
in U.S. Treasury Notes. Interest expense for the year ended December 31, 1997,
amounted to $485,062, an increase of $450,833 over the same period in 1996. The
increase was due primarily to an increased working capital line of credit, a
long term loan with Bank of America, the bridge loans and the additional
interest expense resulting from the issuance of the bridge loan warrants.

         The net loss for the year ended December 31, 1997 was $4,494,062
compared to $788,546 for the year ended December 31, 1996. The difference is a
result of the increased research and development expenses, increased selling,
general and administrative expenses and the decrease in research contract
revenues.

LIQUIDITY AND CAPITAL RESOURCES

         The Company has financed its operations from inception through contract
research revenues and more recently through sales of common stock and
borrowings. During 1997 the Company has received $1,882,000 in net proceeds from
private placements of its Common Stock and received $13,797,000 in net proceeds
from the sale of its Common Stock from its initial public offering. The Company
raised an additional $1,780,000 through a debt/warrant offering from August 1,
1997 through October 6, 1997.

                                       14


<PAGE>

         The Company has also, for working capital purposes, entered into term
loans with a bank to effect borrowings originally in the amounts of $500,000 and
$250,000. As of December 31, 1997, the Company's borrowings under the term loans
were $458,330 and $173,970, respectively.

         As a result of the private placements of debt and equity securities,
the new loan agreements and proceeds from its initial public offering, the
Company's cash and cash equivalents has increased from $55,966 at December 31,
1996 to $6,005,059 at December 31, 1997. In addition, the Company had
investments in U.S. Treasury Notes, with maturities ranging from six months to
one year, of $6,007,713 at December 31, 1997.

         During the year ended December 31, 1997, the Company spent $60,504 on
furniture and equipment and $307,710 on patents.

         During the years ended December 31, 1997 and 1996, the cash used in
operations was $(3,389,420) and $(442,041), respectively. The cash used for
operations was primarily to fund research and development and sales and
marketing expenses related to the introduction and support of its genetic
susceptibility tests.

         The Company anticipates continuing to use its capital primarily to fund
activities related to research and development and marketing, sales and support
of its products. With its existing capital received from the private placement
of debt and equity securities and proceeds from its initial public offering, the
Company believes that its capital resources will be sufficient to provide its
anticipated cash needs for working capital and capital expenditure for at least
the next 13 months although the Company may seek to raise additional capital
before then, depending on various considerations and developments. Thereafter,
if cash generated from operations is insufficient to satisfy the Company's
capital requirements, the Company may have to sell additional equity or debt
securities or obtain credit facilities, assuming the Company can do so on
acceptable terms.

YEAR 2000 COMPLIANCE

         The Company believes that all of its significant computer software
programs are currently Year 2000 compliant. The Company does not expect to incur
any material costs or expenses in connection therewith.

consolidated statements of operations, shareholders' equity, and cash flows for
each of the two years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Medical Science

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Organization and Line of Business
         ---------------------------------
         Medical Science Systems, Inc., a Texas corporation, originally operated
         under two separate corporations, known as Oral Science Systems and Oral
         Science Technologies. In 1995 Oral Science Systems was merged into Oral
         Science Technologies and Oral Science Technologies was renamed Medical
         Science Systems, Inc. The merger was accounted for in a manner similar
         to a pooling of interest. During the year ended December 31, 1997, a
         wholly-owned subsidiary, Medical Science Systems Laboratory Services,
         Inc., was formed which was incorporated in the state of Delaware. (The
         consolidated companies are hereafter referred to as the "Company".)

         The Company is currently developing a line of genetic susceptibility
         tests and therapeutic targets for common diseases. As of December 31,
         1997, the Company has commercially introduced one such product and is
         in various stages of development for several others. The Company
         previously provided clinical trials and research services under
         contract to pharmaceutical companies, and such services generated
         substantially all of the Company's revenues for the year ended December
         31, 1996.

         Principles of Consolidation
         ---------------------------
         The consolidated financial statements include the accounts of the
         Company and its wholly-owned subsidiary. All material intercompany
         accounts and transactions have been eliminated.

         Estimates
         ---------
         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosures of contingent assets and liabilities at the
         date of the financial statements, as well as the reported amounts of
         revenues and expenses during the reported periods. Actual results could
         differ from those estimates.

         Fair Value of Financial Instruments
         -----------------------------------
         The Company measures its financial assets and liabilities in accordance
         with generally accepted accounting principles. For certain of the
         Company's financial instruments including cash and cash equivalents,
         accounts receivable, accounts payable, and accrued expenses, the
         carrying amounts approximate fair value due to their short maturities.
         The amounts shown for long-term debt and capital lease obligations also
         approximate fair value because current interest rates and terms offered
         to the Company for similar debt and lease agreements are substantially
         the same.

                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                                               DECEMBER 31, 1997

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


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         Cash and Cash Equivalents
         -------------------------
         For purposes of the statements of cash flows, the Company considers all
         highly-liquid investments purchased with original maturities of three
         months or less to be cash equivalents.

         Inventories
         -----------
         Inventories principally consist of finished goods and are stated at the
         lower of cost or market, cost generally being determined on a first-in,
         first-out basis.

         Furniture and Equipment
         -----------------------
         Furniture and equipment, including equipment under capital leases, are
         stated at cost, less accumulated depreciation and amortization.
         Depreciation and amortization are provided using the straight-line
         method over the estimated useful lives of three to five years as
         follows:

                  Computer equipment                           3 years
                  Furniture and fixtures                       5 years
                  Office equipment                             3 years
                  Equipment under capital leases          3 to 5 years

         Betterments, renewals, and extraordinary repairs that extend the life
         of the asset are capitalized; other repairs and maintenance charges are
         expensed as incurred. The cost and related accumulated depreciation
         applicable to assets retired are removed from the accounts, and the
         gain or loss on disposition is recognized in the statement of
         operations.

         Patents
         -------
         The cost of acquiring patents, which consists principally of legal
         fees, is being amortized using the straight-line method over their
         useful lives of ten years beginning from the time the patents are
         awarded. The Company was issued three patents in 1997 and currently has
         sixteen patents pending. The Company recognized $2,165 in amortization
         expense for the year ended December 31, 1997. Management periodically
         reviews the patent costs for impairment based on the likelihood of the
         product being successfully brought to market.

         Revenue Recognition
         -------------------
         Revenue from genetic susceptibility tests is recognized when the tests
         have been completed and the results reported to the doctors. Contract
         revenues are recognized ratably as services are provided based on a
         fixed contract price or on negotiated hourly rates. Provision for
         anticipated losses on fixed-price contracts is made in the period such
         losses are identified.

                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                                               DECEMBER 31, 1997

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


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         Concentrations of Risk
         ----------------------
         The Company sells products and provides contract services for customers
         primarily in the United States and extends credit based on an
         evaluation of the customer's financial condition, generally without
         requiring collateral. Exposure to losses on receivables is principally
         dependent on each customer's financial condition. The Company monitors
         its exposure for credit losses and maintains allowances for anticipated
         losses.

         During the year ended December 31, 1997, the Company did business with
         two customers whose sales comprised approximately 12% and 14% of total
         revenues, respectively. Amounts due from these customers represented
         approximately 14% of accounts receivable at December 31, 1997.

         During the year ended December 31, 1997, the Company obtained lab
         services for its genetic susceptibility tests from one company whose
         services comprised approximately 83% of cost of sales.

         During the year ended December 31, 1996, the Company did business with
         three customers whose sales comprised approximately 99% of revenues.

         Research and Development
         ------------------------
         Research and development costs related to the development of new
         products are expensed as incurred.

         Income Taxes
         ------------
         Prior to September 30, 1996, the Company had elected to be treated as
         an "S" corporation for federal and state tax purposes. Effective
         September 30, 1996, the Company terminated such election and became
         taxable as a "C" corporation. The Company will not realize any future
         tax benefits of net operating losses incurred prior to September 30,
         1996.

         The Company accounts for income taxes under the liability method
         required by Statement of Financial Accounting Standards ("SFAS") No.
         109, "Accounting for Income Taxes," which requires the recognition of
         deferred tax liabilities and assets for the expected future tax
         consequences of events that have been included in the financial
         statements or tax returns. Under this method, deferred income taxes are
         recognized for the tax consequences in future years of differences
         between the tax bases of assets and liabilities and their financial
         reporting amounts at each period end based on enacted tax laws and
         statutory tax rates applicable to the periods in which the differences
         are expected to affect taxable income. Valuation allowances are
         established, when necessary, to reduce deferred tax assets to the
         amount expected to be realized. The provision for income taxes
         represents the tax payable for the period and the change during the
         period in deferred tax assets and liabilities.

                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                                               DECEMBER 31, 1997

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


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         Net Income (Loss) Per Share
         ---------------------------
         For the year ended December 31, 1997, the Company adopted SFAS No. 128,
         "Earnings per Share." Basic earnings per share is computed by dividing
         net income (loss) to common stockholders by the weighted-average number
         of common shares outstanding. Diluted earnings per share is computed
         similar to basic earnings per share except that the denominator is
         increased to include the number of additional common shares that would
         have been outstanding if the potential common shares had been issued
         and if the additional common shares were dilutive. Earnings per share
         for 1996 has been restated using the methodologies of SFAS No. 128.
         However, in connection with the Company's initial public offering
         ("IPO"), common stock issued for consideration below the IPO per share
         price during the twelve months before the filing of the registration
         statement, plus options and warrants to purchase common stock issued
         for consideration below the IPO per share price during the same period
         (using the treasury stock method), have been included in the
         calculation of common stock equivalent shares as if they had been
         outstanding throughout the interim period (September 30, 1997) included
         in the IPO prospectus. The determination of common stock and
         equivalents outstanding for the remainder of 1997 has been determined
         on a basis consistent with SFAS No. 128. That is, outstanding options
         and warrants are included in the earnings per share computation using
         the treasury stock method only if they have a dilutive effect. Since
         the Company incurred a net loss for the years ended December 31, 1997
         and 1996, the stock options and warrants outstanding would be
         anti-dilutive, and therefore, basic earnings per share and diluted
         earnings per share are the same.

         Risks and Uncertainties
         -----------------------
         Commercial success of genetic susceptibility tests will depend upon
         their acceptance as medically useful and cost-effective by patients,
         physicians, dentists, other members of the medical and dental
         community, and third-party payers. The Company plans to expend
         substantial financial resources to promote the benefits of the
         Company's susceptibility tests. It is uncertain whether current genetic
         susceptibility tests or others that the Company may develop will gain
         acceptance on a timely basis.

         Research in the field of disease predisposing genes and genetic markers
         is intense and highly competitive. The Company has many competitors in
         the United States and abroad which have considerably greater financial,
         technical, marketing, and other resources available. If the Company
         does not discover disease predisposing genes or genetic markers and
         develop susceptibility tests and launch such services or products
         before their competitors, then sales and earnings may be reduced or
         eliminated.

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


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         Risks and Uncertainties (Continued)
         -----------------------------------
         The Company's ability to successfully commercialize genetic
         susceptibility tests depends on obtaining adequate reimbursement for
         such products and related treatment from government and private health
         care insurers and other third-party payers. Doctors' decisions to
         recommend genetic susceptibility tests will be influenced by the scope
         and reimbursement for such tests by third-party payers. If both
         third-party payers and individuals are unwilling to pay for the test,
         then the number of tests performed will significantly decrease,
         therefore resulting in a reduction of revenues.

         The Company entered into an agreement with Sheffield University,
         whereby the Company will undertake the development and
         commercialization of certain discoveries resulting from Sheffield
         University's research. The agreement is non-cancelable for discoveries
         on which the parties have reached a specific agreement, but may be
         terminated with or without cause by either party upon six-months notice
         with respect to new discoveries on which the parties have not yet
         reached agreement. If Sheffield University terminated the agreement,
         such termination could make the discovery and commercial introduction
         of new products more difficult or unlikely.

         Recently Issued Accounting Pronouncement
         ----------------------------------------
         SFAS No. 130, "Reporting Comprehensive Income," is effective for
         financial statements with fiscal years beginning after December 15,
         1997. SFAS No. 130 establishes standards for reporting and display of
         comprehensive income and its components in a full set of
         general-purpose financial statements. The Company does not expect
         adoption of SFAS No. 130 to have a material effect, if any, on its
         financial position or results of operations.

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


NOTE 5 - NOTES PAYABLE AND REVOLVING LINE OF CREDIT WITH BANK

         In March 1996, the Company entered into a revolving line of credit
         agreement with a bank to borrow up to $250,000, and a note payable of
         $250,000, for working capital purposes and to repay the outstanding
         borrowings under certain promissory notes. In October 1996, the line of
         credit was increased to provide for total borrowings of up to $500,000.
         The line of credit originally matured in March 1997 and was extended to
         June 1997 at which time all outstanding principal was converted into a
         five-year note payable, payable in sixty monthly installments of $8,334
         plus interest. The $500,000 note payable bears interest at the bank's
         prime rate (8.5% at December 31, 1997) plus 1.75%. At December 31,
         1997, the Company had outstanding borrowings of $458,330 under this
         note.

         The $250,000 note payable matures in March 2001 and requires monthly
         payments of principal and interest of $5,222. The $250,000 note payable
         bears interest at a fixed rate of 9.125% per annum. At December 31,
         1997, the Company had outstanding borrowings of $173,970 under this
         note.

         Required principal payments under the notes payable are as follows:

                                         =============

         The notes payable are collateralized by substantially all of the
         Company's assets and accounts receivable. In addition, three of the
         Company's officers have personally guaranteed the Company's obligations
         under the notes payable. The agreements also include certain covenants
         which restrict, among other things, the occurrence of new indebtedness.

NOTE 6 - PROMISSORY NOTES

         In August and September 1997, the Company entered into several
         subscription agreements to sell subordinated Promissory Notes
         ("Notes"). In addition, the Company granted one warrant to purchase
         common stock at an exercise price of $5.50 per share for each $5.00
         loaned. The Company issued Notes in the amount of $1,780,000 and issued
         356,545 warrants to purchase the Company's common stock of which
         $425,000 of notes and 85,000 warrants were issued to officers of the
         Company. The Notes accrued interest at 10% per annum, and all unpaid
         principal and interest were due the earlier of 14 months from the date
         of issuance or the sale of equity securities which results in gross
         proceeds in excess of $6,000,000. The warrants expire five years from
         the date of issuance and are callable by the Company upon the
         occurrence of the Company's common stock traded on a national or
         regional stock exchange and the closing price of the common stock
         equals or exceeds $12.00 per share for thirty consecutive trading days.
         In connection with the issuance of such warrants, the Company
         recognized additional interest expense of $356,545 for the year ended
         December 31, 1997. These notes were repaid in December 1997 with
         proceeds from the IPO.


NOTE 7 - INCOME TAXES

         Prior to September 30, 1996, the Company elected to be taxed as an "S"
         corporation for federal and state income tax purposes; the Company's
         income or loss for such periods was allocated among its shareholders.
         Consequently, the Company has not recorded any tax provision for any
         period prior to such date. Effective September 30, 1996, the Company
         terminated such election and became taxable as a "C" corporation.

         The Company has not recorded a current or deferred provision for
         federal income taxes for the period from October 1, 1996 to December
         31, 1997 due to losses incurred during that period. The provision for
         income taxes represents the minimum required for state franchise taxes.
         To reconcile from the federal statutory tax rate of 34% to the
         Company's effective tax rate of approximately 1%, the deferred tax
         asset valuation reserve is deducted. At December 31, 1997, the Company
         had net operating loss carryforwards of approximately $4,497,000 and
         $2,282,000 for federal and state income tax purposes, respectively,
         expiring in varying amounts through the year 2013, which are available
         to offset future federal and state taxable income. The Company also had
         a research tax credit of approximately $202,000 at December 31, 1997
         that expires in 2013. The ability of the Company to utilize the federal
         and state net operating loss carryforwards may be subject to annual
         limitations under certain provisions of the Internal Revenue Code.

         In June 1996, the Company's shareholders approved a 1,083.333 for 1

                                                               DECEMBER 31, 1997

NOTE 10 - STOCK OPTION PLAN (CONTINUED)

         Nonqualified and incentive stock options are granted at exercise prices
         equal to the fair market value of the common stock on the date of
         grant. One-sixth of the options are generally available for exercise at
         the end of six months and the remainder of the grant is exercisable
         ratably over the next 30-month period provided the optionee remains in
         service to the Company. The Company may also award share appreciation
         rights ("SARs") either in tandem with stock options or independently.
         At December 31, 1997 and 1996, no SARs has been awarded under the Plan.

         The Company has adopted only the disclosure provisions of SFAS No. 123,
         "Accounting for Stock-Based Compensation." It applies Accounting
         Principles Bulletin ("APB") Opinion No. 25, "Accounting for Stock
         Issued to Employees," and related interpretations in accounting for its
         plans and does not recognize compensation expense for its stock-based
         compensation plans other than for restricted stock and options issued
         to outside third parties. If the Company had elected to recognize
         compensation expense based upon the fair value at the grant date for
         awards under this plan consistent with the methodology prescribed by
         SFAS 123, the Company's net loss and loss per share would be reduced to
         the pro forma amounts indicated below:

                                                       Year Ended December 31,
                                                     ---------------------------
                                                         1997           1996
                                                     ------------   ------------
            Net loss
                As reported                          $(4,494,062)   $  (788,546)
                Pro forma                            $(4,796,791)   $  (894,437)
            Basic loss per common share
                As reported                          $     (1.04)   $     (0.18)
                Pro forma                            $     (1.11)   $     (0.21)

         The fair value of these options was estimated at the date of grant
         using the Black-Scholes option-pricing model with the following
         weighted-average assumptions for the years ended December 31, 1997 and
         1996: dividend yields of 0% and 0%; expected volatility of 60% and 70%;
         risk-free interest rates of 5.8% and 6.0%; and expected life of 7 years
         and 3 years, respectively. The weighted-average fair value of options
         granted during the years ended December 31, 1997 and 1996 was $2.55 and
         $1.87, respectively, and the weighted-average exercise price was $3.88
         and $3.70, respectively.

NOTE 10 - STOCK OPTION PLAN (CONTINUED)

         The Black-Scholes option valuation model was developed for use in
         estimating the fair value of traded options which have no vesting
         restrictions and are fully transferable. In addition, option valuation
         models require the input of highly subjective assumptions including the
         expected stock price volatility. Because the Company's employee stock
         options have characteristics significantly different from those of
         traded options, and because changes in the subjective input assumptions
         can materially affect the fair value estimate, in management's opinion,
         the existing models do not necessarily provide a reliable single
         measure of the fair value of its employee stock options.

NOTE 10 - STOCK OPTION PLAN (CONTINUED)

         The Plan also provides for the award of restricted stock to eligible
         persons. Such awards may be at prices not less than 85% of the fair
         market value of the Company's common stock as determined by the Board
         of Directors. In addition, stock bonuses may be awarded to certain
         employees or officers of the Company at the discretion of the Board of
         Directors. In September 1996, the Company's Board of Directors issued a
         stock bonus of 5,000 shares to a consultant of the Company. The
         estimated fair value of such shares at the date of the award was
         charged to expense in 1996. As of December 31, 1997, the Company has
         not awarded any restricted stock awards.

         In May 1997, the Company offered to its employees the opportunity to
         receive stock options to acquire shares of the Company's common stock
         at $5.00 to $5.50 per share in an exchange for a reduction in salary.
         Employees elected to reduce their salaries up to 100% for the period
         from May 1997 to October 1997 in exchange for 600 stock options for
         each $1,000 of salary reduction. As a result, the Company issued
         267,079 stock options in exchange for salary reductions of $445,132.
         The Company recorded an expense relating to the issuance of these stock
         options in the amount of $74,189 per month for each of the six months
         from May 1997 to October 1997.


NOTE 11 - COMMITMENTS AND CONTINGENCIES

         The Company leases its office space under non-cancelable operating
         leases expiring through April 2001. The Company also leases certain
         office furniture and equipment under capitalized lease obligations.
         Future minimum rental commitments under lease agreements with initial
         or remaining terms of one year or more at December 31, 1997 are as

         the development and commercialization of any discoveries resulting from
         Sheffield University's research. The proceeds distributed to Sheffield
         University from the sale or license of products or technologies
         developed or commercialized under this agreement will be determined on
         a case-by-case basis.

         Either party may terminate the agreement with no less than six-months
         notice.

NOTE 12 - RELATED PARTIES

         During the year ended December 31, 1997, the Company formed a joint
         venture with a subsidiary of another company whose President and Chief
         Executive Officer is also a Director of the Company. The purpose of the
         joint venture is to market the Company's computer modeling technology
         and to provide marketing information to certain users of the Company's
         genetic susceptibility tests. The Company believes that the terms of
         joint venture are at least as favorable as would be available from any
         other company in an arm's length transaction. At December 31, 1997, the
         joint venture had not commenced operations.


NOTE 13 - SUBSEQUENT EVENTS (UNAUDITED)

         Subsequent to December 31, 1997, 152,400 incentive stock options were
         issued to certain employees. The warrants entitle the holder to
         purchase shares of the Company's common stock at prices from $4.38 to
         $4.75 per share and expire ten years from the date of issuance.

         Subsequent to December 31, 1997, 11,500 non-qualified stock options
         were issued to certain non-employees. The warrants entitle the holder
         to purchase shares of the Company's common stock at a price of $4.38
         per share and expire ten years from the date of issuance.

        The current price for a Test Administration to French customers is Two
Hundred and Ten U.S. dollars ($210). MSS and Representative will discuss the

MSS or, if no written acceptance is given by MSS, until the order is shipped and

any order as binding upon MSS, and MSS reserves the absolute right, in its sole
discretion, to reject any order placed through Representative.


                                       6
<PAGE>


        6.3 TERMS AND CONDITIONS. The terms and conditions of this Agreement
will apply to each order accepted or shipped by MSS or its service center
hereunder. The terms of this Agreement will not be amended or changed by the
terms of any purchase order, acknowledgment, invoice or similar document, even
though MSS or its service center may have signed or accepted such documents. All
orders of PST solicited by Representative will be according to MSS's prices,
payment terms and other terms and conditions in effect at the time of the order.

        6.4 BILLING. All MSS Products or Services for which orders are accepted
by MSS will be shipped and billed by MSS or its service center directly to the
customer. All invoice payments will be made directly to MSS or its service
center by the customer.

        6.5 DELIVERY AND CANCELLATION OF ORDERS. MSS will use reasonable efforts
to meet Representative's or a customer's requested delivery schedules for orders
for PST, but MSS reserves the right to refuse, cancel or delay shipment to a
customer if the customer (i) fails to make any payment, (ii) fails to meet the
credit or financial requirements established by MSS, or (iii) otherwise fails to
comply with the terms and conditions of this Agreement. MSS also reserves the
right to discontinue the distribution of any versions of PST at any time and to
cancel any orders therefor without liability of any kind to Representative or
any other person. No cancellation, refusal or delay for any of the reasons set
forth above will be deemed a termination or breach of this Agreement by MSS.

        6.6 ALLOCATION OF THE MSS PRODUCTS. Should orders for PST exceed the
available inventory, MSS or its service center will allocate its available
inventory and make deliveries on a basis MSS or its service center deems
equitable, in its sole discretion.

        6.7 PARTIAL SHIPMENTS. MSS or its service center may make partial
shipments to customers on account of orders placed through Representative, to be
separately invoiced.

7.      REPRESENTATIVE COMMISSIONS.
        ---------------------------

        In consideration of the services of Representative under this Agreement,
MSS will pay Representative commissions as set forth below:

        7.1 CRITERIA FOR COMMISSIONS. Representative is eligible to receive
commissions only with respect to orders of PST expressly authorized hereunder
that MSS or its service center has accepted and that were placed by customers in
the Territory. In no case will commissions be paid on orders by customers from
whom Representative is not authorized to solicit orders.

        7.2 COMMISSION BASIS. As to orders meeting the criteria of Section 7.1,
MSS will pay Representative commissions in accordance with the following terms:


                                       7
<PAGE>


               (a) SALES GENERATED WHOLLY BY REPRESENTATIVE. For orders of PST
        placed by non-institutional customers in the territory, MSS will pay
        Representative a commission at the Commission Rates set forth in Exhibit
        B hereto, calculated as follows

                      Commission = Applicable Commission Rate x Commission Basis

        "COMMISSION BASIS" is defined as the amount invoiced by MSS or MSS's
        service center for Test Administrations performed and sold solely as a
        result of the sales efforts of Representative. Commission Basis shall
        not include any amounts charged for Sample Collection Materials and any
        associated separately itemized incidental charges, such as shipping and
        handling of Sample Collection Materials, Samples, or the results of Test
        Administrations.

               (b) SALES TO INSTITUTIONS. Representative acknowledges that MSS
        will be promoting use of PST directly to institutions such as managed
        care organizations, insurance companies, and government healthcare
        organizations. In the event that such an institution to which MSS has
        been promoting agrees to cover the cost of, or to mandate the use of,
        PST for all patients under its care or covered by its policy, then a
        separate commission schedule will be negotiated with respect to revenue
        generated from sales to such institutions or reimbursed by such
        institutions. Sales made to an institution by Representative without any
        participation by MSS will entitle Representative to commissions at the
        rates set forth in Section 7.2(a) above.

        7.3 TIMING OF PAYMENT. MSS will report and pay commissions earned by
Representative on orders of PST monthly within sixty (60) days after the close
of each month, or within thirty (30) days after the close of each month with
respect to Test Administrations for which the processing fee is paid by the
customer when the Sample is submitted. In the event that MSS is required to bill
Patients directly, rather than Clinicians, for Test Administrations, the parties
will re-negotiate in good faith the time frames within which commissions will be
paid based on the expected payment time frames for Patients.

        7.4 REFUNDS, BAD DEBT AND THE LIKE. No commission will be due to
Representative, and any commission paid will be refunded by Representative or
offset against other commissions due Representative, with respect to orders of
PST in the event that, and to the extent that: (i) the invoices with respect to
such orders are uncollectable or otherwise become bad debt; (ii) such orders are
rejected or returned in whole or in part, (iii) any portion of the price charged
with respect to such orders becomes subject to adjustment or refund or rebate to
the customer, or (iv) any portion of the price for such orders must be returned
by MSS to the customer in connection with any proceeding, whether voluntary or
involuntary, involving such customer under any bankruptcy, insolvency or
debtor's relief law. MSS may deduct any commission amounts owed pursuant to this
Section 7.4 by Representative to MSS from any commissions owed by MSS to
Representative. Commission adjustments to reflect uncollectable amounts or other
bad debts will be reconciled each six (6) months.


                                       8
<PAGE>

8.      REPORTS
        -------

        Within fifteen (15) days of the end of each calendar month,
Representative will provide to MSS's Flagstaff offices a written report
summarizing, for the month immediately preceding the report, Representative's
efforts to promote PST by geographic areas or other categories as MSS may
designate from time to time, the number of Sample Collection Materials
distributed for evaluation at no charge and to whom such materials were
distributed. Representative will promptly notify MSS in writing of any claim or
proceeding involving advertisement or distribution of PST within ten (10) days
after Representative learns of such claim or proceeding. Representative will
report promptly to Company all suspected defects in PST.

9.      CONFIDENTIALITY.
        ----------------

        9.1    OBLIGATIONS.  Representative agrees:

               (i) that it will not disclose to any third party or use, other
than as expressly permitted hereunder, any Confidential Information of MSS;

               (ii) that it will not disclose to any third party other than its
attorneys, accountants and other professional advisors the terms of this
Agreement, except as may be necessary to enforce this Agreement; and

               (ii) that it will take all reasonable measures to maintain the
confidentiality and to prevent the unauthorized use of all Confidential
Information in its possession or control, which will in no event be less than
the measures it uses to maintain the confidentiality of its own information of
similar importance.

        9.2 INJUNCTIVE RELIEF. Representative acknowledges that unauthorized use
or disclosure of the Confidential would cause substantial harm to MSS that could
not be remedied by the payment of damages alone. Accordingly, Representative
agrees that MSS will be entitled to preliminary and permanent injunctive relief
and other equitable relief for any breach of this Section 9.

10. PROPRIETARY RIGHTS.
    -------------------

        10.1 MSS'S OWNERSHIP. MSS is and will remain the sole and exclusive
owner of all Intellectual Property Rights in PST.


                                       9
<PAGE>


        10.2 REPRESENTATIVE'S DUTIES. Representative will use its reasonable
efforts to protect MSS's Intellectual Property Rights in PST and will report
promptly to MSS any infringement of such rights of which Representative becomes
aware.

        10.3 THIRD PARTY INFRINGEMENT. MSS reserves the sole and exclusive right
at its discretion to assert claims against third parties for infringement or
misappropriation of its Intellectual Property Rights in PST.

        10.4   TRADEMARKS.

               (a) If any advertisement or other marketing material used by
Representative makes any statement as to the technical features or capabilities
of PST beyond the information provided to Representative by MSS, Representative
will first obtain the written approval of MSS prior to publishing such
advertisement or material.

               (b) Subject to the terms and conditions of this Agreement, MSS
grants Representative a non-exclusive, non-transferable license for the term of
this Agreement to use in Representative's marketing of PST only those Marks of
MSS that MSS has approved for use on or in conjunction with the marketing,
promotion and sale of PST, provided that such use is in accordance with MSS's
trademark usage guidelines then in effect. Such use must reference such Marks as
being owned by MSS. Nothing in this Agreement grants Representative ownership or
any rights in or to use any Marks, except in accordance with this license. The
rights granted to Representative in this license will terminate upon any
termination or expiration of this Agreement. Upon such termination or
expiration, Representative will no longer make any use of any Marks.
Representative has paid no consideration for the use of MSS's Marks and
Representative agrees that it will not at any time (i) claim any interest in any
of MSS's Marks; (ii) register, seek to register, or cause to be registered any
of MSS's Marks, other than in MSS's name and at MSS's specific request; or (iii)
adopt and use any trademark, tradename, brand name, service mark, service name,
and/or logo that might be confusingly similar to MSS's trademarks, tradenames,
brand names, service marks, service names or logos. Representative will assist
MSS, if requested and at MSS's expense, to register MSS's trademarks in MSS's
name in the Territory.

11.     WARRANTY.
        ---------

        11.1 POWER AND AUTHORITY. MSS warrants to Representative that it has
sufficient right and authority to grant to Representative all rights that MSS
grants under this Agreement.

        11.2 DISCLAIMER OF OTHER WARRANTIES. THE WARRANTIES IN THIS SECTION ARE
IN LIEU OF ALL OTHER WARRANTIES, EXPRESS AND IMPLIED, AND MSS EXPRESSLY
DISCLAIMS ALL SUCH OTHER WARRANTIES, INCLUDING BUT NOT LIMITED TO ANY IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
NONINFRINGEMENT. MSS DOES NOT MAKE ANY WARRANTIES TO REPRESENTATIVE WITH RESPECT
TO PST OR ANY OTHER PRODUCT OR SERVICE OF MSS OR ITS SERVICE CENTERS.


                                       10
<PAGE>


12.     INDEMNITIES.
        ------------

        12.1 DISTRIBUTION INDEMNITY. Subject to the terms of Section 12.2,
Representative agrees to indemnify MSS against any third party claims against
MSS for loss, damage, liability, or expense (including but not limited to
attorneys' fees) arising out of any acts or omissions of Representative in
connection with its activities under this Agreement.

        12.2   INFRINGEMENT INDEMNITY.

               (a)    DUTY TO INDEMNIFY AND DEFEND.

                      (i)  Subject to the limitations set forth in Section 13,
MSS will indemnify Representative against, and will defend or settle at MSS's 
own expense, any action or other proceeding brought against Representative to 
the extent that it is based on a claim that the use of PST as delivered under 
this Agreement infringes any copyright, misappropriates any trade secret, or

or proceeding to the extent attributable to any such claim.

                    (iii)  MSS will have no obligation under this Section as to
any action, proceeding, or claim unless: (A) MSS is notified of it promptly; (B)
MSS has sole control of its defense and settlement; and (C) Representative 
provides MSS with reasonable assistance in its defense and settlement.

               (c)    SOLE REMEDY.  THE FOREGOING ARE MSS's SOLE AND EXCLUSIVE

        13.2 EXCLUSION OF DAMAGES. IN NO EVENT WILL MSS BE LIABLE TO
REPRESENTATIVE FOR ANY SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER

DAMAGE.

        13.3 FAILURE OF ESSENTIAL PURPOSE. The parties have agreed that the

survive and apply even if any limited remedy specified in this Agreement is
found to have failed of its essential purpose.

        13.4 BASIS OF THE BARGAIN. Representative acknowledges that MSS has set
its prices and entered into this Agreement in reliance upon the limitations of
liability and the disclaimers of warranties and damages set forth herein, and
that the same form an essential basis of the bargain between the parties.

14. TERM AND TERMINATION.
    ---------------------

        14.1 TERM. The term of this Agreement will begin on the Effective Date
and will continue for five (5) years from the Launch Date unless it is
terminated earlier in accordance with the provisions hereof. Thereafter, this
Agreement will automatically be renewed for additional one year periods unless

Agreement at least six (6) months in advance of the automatic renewal date. Each
party acknowledges that the other is not under any obligation to renew this
Agreement.

        14.2 EVENTS OF TERMINATION FOR CAUSE. Either party will have the right
to terminate this Agreement if:

               (a) the other party breaches any material term or condition of
this Agreement and fails to cure such breach within thirty (30) days after
written notice, PROVIDED, HOWEVER, that MSS shall have no right to terminate
this Agreement based solely on failure by Representative to meet its annual
minimum sales requirements under Section 3.4 during the first two (2) years
after the Launch Date;

               (b) the other party becomes the subject of a voluntary petition
in bankruptcy or any voluntary proceeding relating to insolvency, receivership,

<PAGE>


               (c) the other party becomes the subject of an involuntary
petition in bankruptcy or any involuntary proceeding relating to insolvency,
receivership, liquidation, or composition for the benefit of creditors, if such
petition or proceeding is not dismissed within sixty (60) days of filing.

        14.3 TERMINATION BY MSS FOR FAILURE TO MEET MINIMUM SALES. Except during
the first two (2) years after the Launch Date, MSS may terminate this Agreement
upon six (6) months written notice to Representative in the event that
Representative fails to meet any applicable annual minimum sales requirements
set pursuant to Section 3.4 above.

        14.4 TERMINATION UPON ELECTION OF REPRESENTATIVE. Representative may
terminate this Agreement for any reason at its sole discretion, effective at any
time after the first two (2) years after the Launch Date, by giving MSS at least
one (1) year's advance written notice of such termination.

        14.5 COMMISSION RIGHTS ON TERMINATION. Upon termination of this
Agreement, Representative will be entitled to commissions on orders for PST that
satisfy the requirements of this Agreement only if such orders are placed for
shipment and are accepted by MSS prior to the effective date of termination and
only if such orders are shipped within sixty (60) days after such termination
date. Notwithstanding the foregoing, if this Agreement is terminated for cause
by MSS, Representative shall be entitled only to commissions for orders accepted
by MSS and shipped prior to the effective date of termination.

        14.6   EFFECT OF TERMINATION.

               Upon termination or expiration of this Agreement: (i)
Representative will immediately return to MSS all Sample Collection Materials
and all copies of Confidential Information in its possession or control, and an

done so; (ii) Representative will immediately cease to use any MSS Mark; (iii)
Representative will immediately return all marketing material provided to
Representative by MSS; and (iv) Representative will immediately refund to MSS
any excess commissions due back to MSS pursuant to the provisions of Section 7.

OTHER FOR DAMAGES OF ANY KIND, INCLUDING INCIDENTAL OR CONSEQUENTIAL DAMAGES, ON
ACCOUNT OF THE TERMINATION OR EXPIRATION OF THIS AGREEMENT IN ACCORDANCE WITH
ITS TERMS. REPRESENTATIVE WAIVES ANY RIGHT IT MAY HAVE TO RECEIVE ANY
COMPENSATION OR REPARATIONS ON TERMINATION OR EXPIRATION OF THIS AGREEMENT UNDER
THE LAW OF THE TERRITORY OR OTHERWISE, OTHER THAN AS EXPRESSLY PROVIDED IN THIS
AGREEMENT. Without limiting the generality of the preceding sentence, neither
party will be liable to the other on account of termination or expiration of
this Agreement for reimbursement or damages for the loss of goodwill,
prospective profits or anticipated income, or on account of any expenditures,
investments, leases or commitments made by either party or for any other reason
whatsoever based upon or growing out of such termination or expiration.

        14.8 NONEXCLUSIVE REMEDY. Except as otherwise provided in this
Agreement, the exercise by either party of any remedy under this Agreement will

        14.9 SURVIVAL. The rights and obligations of the parties contained in
Sections 9 (Confidentiality), 10 (Proprietary Rights), 13 (Limitations of
Liability), and 14.6 (Effect of Termination) will survive the termination or
expiration of this Agreement.

15. COMPLIANCE WITH LAW.
    --------------------

        15.1 GENERAL COMPLIANCE. Each party agrees to comply with all applicable
laws, rules, and regulations in connection with its activities under this
Agreement.

        15.2 U.S. EXPORT CONTROLS. This Agreement is subject to and conditioned
upon compliance with the U.S. Export Administration Act and the applicable
regulations thereunder (collectively, the "U.S. EXPORT LAWS"), as well as any
other laws of the U.S. affecting the export of technology. Representative agrees
to comply fully with the U.S. Export Laws and to provide MSS with such
documentation, assurances and access to records as may be required to obtain
licenses under the U.S. Export Laws. Representative certifies that neither the
MSS Products, the technical data relating to the MSS Products, nor any direct
product of the MSS Products: (a) are intended to be used for any purposes
prohibited by the U.S. Export Laws, including but not limited to nuclear
proliferation; nor (b) are intended to be shipped or exported either directly or
indirectly to any country to which the U.S. has prohibited shipment.

16.     ARBITRATION
        -----------

        16.1 AGREEMENT TO SUBMIT. Except as provided below, the parties agree to
submit disputes between them relating to this Agreement and its formation,
breach, performance, interpretation and application, to arbitration as follows.

        16.2 PROCEDURE. Arbitration will be in London, England under the
Arbitration Rules of the United Nations Commission on International Trade Law
("UNCITRAL"). Within thirty (30) days after either party receives a demand for
arbitration by the other, the parties will agree on a single arbitrator who will
have knowledge of and experience in dealing with the biotechnology industry
and/or products similar to that of PST. In the event that the parties cannot
agree, UNCITRAL will appoint an arbitrator in accordance with its rules, which
arbitrator will have knowledge of and experience in dealing with the
biotechnology industry and/or products similar to that of PST. Unless the
arbitrator finds that exceptional circumstances justify delay, the hearing will
be completed, and an award will be rendered in writing, within forty-five (45)
days after commencement of the hearing. All evidence will be presented to the
arbitrator, and the arbitration will be conducted, in the English language. The
award rendered in arbitration will be final and binding and may be enforced in
any court of competent jurisdiction. The arbitrator shall have the authority to
grant any equitable and legal remedies that would be available in any judicial
proceeding instituted to resolve a disputed matter.


                                       14
<PAGE>


        16.3 DISCOVERY AND EVIDENCE. Either party will have the right to
discovery of evidence, but by the following methods only: requests for
production of documents and depositions of no more than five (5) individuals.
The arbitrator will supervise discovery and may, at the request of either party,
limit discovery by the other or award payment of the costs and expenses of
discovery (including reasonable attorneys' fees) to the requesting party for
good cause shown. All discovery will be completed, and the arbitration hearing
will commence, within ninety (90) days after appointment of the arbitrator, and
the arbitrator will enforce this requirement strictly. Subject to the foregoing,
discovery matters will be governed by the Federal Rules of Civil Procedure as
applicable to civil actions in the United States District Courts.

        16.4 EVIDENCE. Each party agrees to supply to the arbitrator in
accordance with a timetable to be established by the arbitrator such materials
as the arbitrator may reasonably require in order to render a decision. Each
party shall supply to the other party hereto copies of any and all materials
which are supplied to the arbitrator concurrently with delivery of such
materials to the arbitrator. In addition, each party shall supply to the other
party at least ten (10) business days prior to the commencement of any hearing
in the arbitration copies of any and all documents which such party intends to
introduce or upon which such party intends to rely in connection with such
hearing, as well as a list of any and all witnesses whose testimony such party
intends to introduce in connection with such hearing. Additional documents or
witnesses may be introduced only if the arbitrator determines that good cause
has been shown. Each party shall also have the right to submit written briefs to
the arbitrator in accordance with a timetable to be established by the
arbitrator. All testimony of witnesses at any arbitration proceeding held
pursuant to these provisions shall be taken under oath. To the extent either
party maintains in good faith that any documents submitted or testimony
introduced in connection with such arbitration contain confidential information
or trade secrets, the parties shall negotiate in good faith in an effort to
reach agreement regarding terms and conditions for keeping such materials and
testimony confidential. If the parties are unable to agree upon such terms, the
arbitrator shall have the right to impose appropriate restrictions to maintain
the confidentiality of any confidential information or trade secrets in
connection with the arbitration.

        16.5 BURDEN OF PROOF. For any claim submitted to arbitration, the burden
of proof shall be as it would be if the claim were litigated in a judicial
proceeding in the federal district courts of the State of California.

        16.6 PAYMENT OF COSTS. Each party hereby agrees to pay one-half of the
compensation to be paid to the arbitrator in any arbitration under this Section
16 and one-half of the costs of transcripts and other expenses of the


                                       15
<PAGE>

arbitration proceedings; provided, however, that the prevailing party in any
arbitration proceeding as determined by the arbitrator shall be entitled to an
award of its direct costs and reasonable expenses of attorneys, accountants and
other professionals incurred in connection with the proceeding (but not
including reimbursement of the compensation paid by such party to the
arbitrator), to be paid by the losing party. In the event of a dispute as to
whether a party qualifies as a prevailing party under this Section 16.6, the
arbitrator shall resolve such dispute and may apportion such costs, fees and
expenses between the parties as the arbitrator deems just and equitable.

        16.7 ATTORNEYS' FEES IN RELATED ACTIONS. In the event of any legal
action relating to the arbitration, including any action to stay the
arbitration, to vacate, modify or correct any award or otherwise, the prevailing
party in the action as determined by the court will be entitled to recover from
the other its court costs and reasonable fees and expenses of attorneys,
accountants and other professionals incurred in connection with the action,
including such costs, fees and expenses upon appeal.

        16.8 EXCEPTIONS. Neither party will be required to arbitrate any dispute
relating to actual or threatened: (a) unauthorized disclosure of Confidential
Information or (b) violation of MSS's Intellectual Property Rights. Either party
will be entitled to have injunctive, preliminary or other equitable relief, in
addition to damages, including reasonable attorneys' fees and costs, to remedy
any actual or threatened violation of its rights with respect to which
arbitration is not required hereunder.

17.     GENERAL.

        17.1 ASSIGNMENT. This Agreement will bind and inure to the benefit of
each party's permitted successors and assigns. Representative may not assign

authorities, denial of or delays in processing of export license applications,
fire, floods, earthquakes, accidents, strikes, or fuel crises, provided that

the power to bind the other or incur obligations on the other's behalf without
the other's prior written consent.

and exclusive agreement between the parties with respect to the subject matter
hereof, superseding and replacing any and all prior agreements, communications,

Agreement may only be modified, or any rights under it waived, by a written
document executed by both parties.

        17.9 CHOICE OF LANGUAGE. The original of this Agreement has been written

interpretation and enforcement of this Agreement. Representative waives any
right it may have under the law of Representative's Territory or otherwise to
have this Agreement written in any language other than English.
