We develop genetic tests which
indicate whether a person is more
likely to develop or will be more
severely affected by certain common
diseases which are treatable and
preventable. We recently began
marketing our initial test related to
periodontitis (gum disease). Provided
that our clinical trials continue to
produce favorable results, we intend
to commence marketing our other
genetic tests which indicate
susceptibility to osteoporosis (bone
disease), coronary artery disease
(heart disease) and diabetic
retinopathy (blindness associated with
diabetes) in 1998 and 1999.

MEDICAL SCIENCE SYSTEMS, INC.                                            Summary
 
             ABOUT OUR COMPANY
 
             Our company has developed genetic tests which indicate whether an
             individual is genetically more likely to be affected or more
             severely affected by certain common diseases which are treatable
             and preventable. We have focused on four diseases initially:
             periodontitis (gum disease), osteoporosis (bone disease), coronary
             artery disease (heart disease) and diabetic retinopathy (blindness
             associated with diabetes). We have identified several 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 be more severe. Moreover, we are the only company that
             we know of that has brought to market a test (our periodontal
             susceptibility test) that identifies a genetic marker which
             indicates a greater susceptibility to a disease which is treatable
             and preventable.
 
   
             Our company's ability to identify genetic markers related to common
             diseases is enhanced by a strategic alliance with Sheffield
             University. Sheffield University provides us with access to
             critical biotechnology research in molecular genetics. This
             arrangement helps provide for the development of additional genetic
             testing products in the future and reduces our capital costs
             relative to biotechnology firms that support large in-house
             research programs. See "Competitive Advantages" at page 42.
    
 
   
             We have ten (10) patent applications pending, including
             applications covering each of our four genetic susceptibility
             tests. We have also been issued one patent related to our computer
             modeling technology. In June 1997, the United States Patent and
             Trademark Office notified us that the patents for our periodontal
             and osteoporosis susceptibility tests are expected to issue. While
             the issuance of those patents is likely, the Patent and Trademark
             Office could disallow the patents at any time prior to the actual
             issue date. See "Intellectual Property" at page 40.
    
 
             MISSION
 
             Our mission is to improve patient care and treatment outcomes by
             incorporating genetic information about a patient's susceptibility
             to disease into overall risk assessment and treatment planning. We
             believe that doctors and dentists will use our genetic
             susceptibility tests to assess the risk involved for any particular
             patient and to adopt appropriate treatments or therapy, including
             preventive measures.

             PRODUCTS AND SERVICES
 
                    PERIODONTAL SUSCEPTIBILITY TEST
 
                        - Description.  Our periodontal susceptibility test is a
                          genetic test capable of detecting individuals with an
                          increased susceptibility to developing severe gum
                          disease (periodontitis). Periodontitis is a
                          bacterially-induced chronic inflammation that destroys
                          the collagen fibers and bone that support the
                          teeth -- ultimately resulting in tooth loss.
 
                        - Market.  According to industry data, in the United
                          States alone, an estimated one-third of all adults, or
                          67 million people, suffer from some form of
                          periodontitis. Approximately 13 million people seek
                          professional treatment annually for periodontal
                          disease, resulting in over 17 million periodontal
                          procedures and annual expenditures of approximately $6
                          billion. Because of the great prevalence of
                          periodontitis, we believe that a substantial portion
                          of the United States' population receiving dental care
                          will be our initial target market.
 
                        - Launch.  On October 3, 1997, we commercially launched
                          our periodontal susceptibility test at the American
                          Academy of Periodontology's Annual Meeting in San
                          Diego, California.
 
                    OSTEOPOROSIS SUSCEPTIBILITY TEST
 
                        - Description.  Our osteoporosis susceptibility test is
                          a genetic test capable of detecting individuals with
                          an increased susceptibility to developing
                          osteoporosis. Osteoporosis is a disease which causes a
                          decrease in the amount of normal bone, making the
                          affected individual more susceptible to fractures.
 
                        - Market.  According to industry data, in the United
                          States alone, an estimated 28 million people, suffer
                          from osteoporosis. Post-menopausal osteoporosis,
                          stemming from the loss of estrogen, affects more than
                          one-half of all women over 65 years of age and has
                          been detected in as many as 90% of the women over age
                          75. Osteoporosis is responsible for a majority of the
                          1.5 million bone fractures each year and leads to
                          disabilities costing more than $10 billion in medical,
                          social and nursing home costs.
 
   
                        - Launch.  We have confirmed the results of our initial
                          trials which demonstrated a relationship between a
                          certain genetic marker and an individual's likelihood
                          to develop or be more severely affected

                          by osteoporosis. We are currently gathering
                          information on the clinical utility of our
                          osteoporosis susceptibility test. Provided that our
                          clinical trials continue to produce favorable results,
                          we anticipate commercially launching this test in late
                          1998. See "Pre-Marketing Trials/Status of
                          Susceptibility Tests" at pages 35 and 36; "Difficulty

                    CORONARY ARTERY DISEASE SUSCEPTIBILITY TEST
 
                        - Description.  Our coronary artery disease
                          susceptibility test is a genetic test capable of
                          detecting individuals with an increased susceptibility
                          to developing coronary artery disease (or "CAD"). CAD
                          is a condition where the arteries that supply blood to
                          the heart have become partially obstructed by plaque
                          accumulation. CAD results in heart attacks due to
                          damage to the heart muscle when blood supply (and
                          therefore oxygen) is cut off and heart muscle cells
                          die. An individual testing positive under our CAD
                          susceptibility test has between a 2.4 to 5.4 times
                          greater change of developing coronary artery disease
                          than the general population.
 
   
                        - Market.  More than one in four Americans, or about 60
                          million, now have some form of cardiovascular disease.
                          Cardiovascular diseases kill nearly one million
                          Americans every year. Every year since 1919,
                          cardiovascular disease has been the number one cause
                          of death in the United States. Approximately 13.5
                          million Americans suffer from coronary artery disease,
                          and approximately half a million Americans die each
                          year from this disease.
    
 
   
                        - Launch.  We have confirmed the results of our initial
                          trials which demonstrated a relationship between a
                          certain genetic marker and an individual's likelihood
                          to develop or be more severely affected by coronary
                          artery disease. We are currently gathering information
                          on the clinical utility of our coronary artery disease
                          test. Provided that our clinical trials continue to
                          produce favorable results, we anticipate commercially
                          launching this test sometime in 1999. See
                          "Pre-Marketing Trials/Status of Susceptibility Tests"

                    DIABETIC RETINOPATHY SUSCEPTIBILITY TEST
 
 
                        - Description.  Our diabetic retinopathy susceptibility
                          test is a genetic test capable of detecting diabetic
                          individuals who have an increased susceptibility to
                          developing sight-threatening retinopathy. Diabetic
                          retinopathy refers to diabetic complications

                          affecting the retina that predictably lead to severe
                          vision loss or even blindness.
 
                        - Market.  In the United States there are approximately
                          16 million people suffering from diabetes. It is
                          estimated that only one-half of this number have been
                          diagnosed. Diabetic retinopathy is one of the most
                          common complications of diabetes. It is the fourth
                          leading cause of legal blindness in the U.S. and the
                          leading cause of blindness in people ages 20 to 74.
                          Each year 15,000 to 39,000 people lose their sight
                          from diabetic retinopathy.
 
   
                        - Launch.  We are currently confirming the results of
                          our initial trials which demonstrated a relationship
                          between a certain genetic marker and a diabetic
                          individual's likelihood to develop diabetic
                          retinopathy. Upon completion of the confirmatory
                          trials more information will be gathering regarding
                          the clinical utility of the diabetic retinopathy test.
                          Provided that our confirmatory and subsequent clinical
                          trials produce favorable results, we anticipate
                          commercially launching this test sometime in 1999. See
                          "Pre-Marketing Trials/Status of Susceptibility Tests"

             COST OF PRODUCTS AND SERVICES
 
             We have recently commercially launched our periodontal
             susceptibility test and are marketing the test at $210 per test.
             Although we cannot be certain, we anticipate that the remainder of
             our genetic susceptibility tests will be marketed at a price
             between $200 and $250. Final pricing of these other tests will be
             determined at the time of commercial launch. We anticipate our
             direct cost (exclusive of sales and marketing) on a per test basis
             to be between $45-$80 depending primarily upon volume
             considerations.
 
   
             RISKS OF INVESTING
    
 
   
                  An investment in our company is subject to many risks. We
             summarize some of the most serious risks below. A more detailed
             list of the risk factors is found under "Risk Factors" at page 9.
             You should read and understand all risk factors before making your
             decision to invest.
    
 
                        - Uncertainty of Market Acceptance for Genetic
                          Susceptibility Tests.  Consumers may not accept our
                          current genetic susceptibility tests or others in
                          development or may accept the tests much later than we
                          anticipate.
 
                        - New Business Venture.  Our genetic susceptibility
                          testing business is relatively new and may be affected
                          significantly by

                          unknown economic and market conditions over which we
                          have no control.
 
                        - History of Operating Losses; Accumulated Deficit;
                          Uncertainty of Future Profitability.  Our company
                          incurred a net loss of $788,546 in 1996 and
                          anticipates a net loss of approximately $4.0 million
                          in 1997. As of September 30, 1997, our accumulated
                          deficit was approximately $3.91 million. It is
                          uncertain when we will become profitable.
 
                        - Intense Competition.  Our company faces intense
                          competition related to the discovery and use of
                          disease predisposing genes and genetic markers. Even
                          after our discovery of the genetic markers, our
                          competition may find and patent the same markers
                          before we do or may find other markers for the same
                          diseases. Additionally, our competitors may have
                          greater resources enabling them to more effectively
                          market their discoveries.
 
                        - Difficulty of Developing Genetic Susceptibility
                          Tests.  It is uncertain whether we will be successful
                          in bringing our complete portfolio of tests to market.
                          Even after identifying a genetic marker, many
                          additional trials must be run in order to verify and
                          confirm the test's accuracy and utility. Any delay in
                          clinical trials or negative clinical results could
                          slow or prevent our ability to successfully market our
                          tests.
 
                        - Uncertainty of Insurance Reimbursement.  It is
                          uncertain whether insurers and third-party payors will
                          elect to reimburse patients for the cost of the
                          genetic susceptibility tests. If insurers or
                          third-party payors elect not to reimburse patients, it
                          is uncertain whether individuals will elect to pay
                          directly for our tests.
 
                        - Reliance on Collaborative Partners.  We have a
                          collaborative research relationship, evidenced by an
                          exclusive worldwide agreement, with the Section of
                          Molecular Medicine at Sheffield University.
                          Additionally, we have entered into agreements with
                          Sheffield University governing each of our individual
                          tests. If these agreements were terminated, we would
                          need to enter into additional collaborative
                          arrangements in order to continue to build a future
                          pipeline of new products.
 
                        - Uncertain Ability to Protect Proprietary
                          Technology.  The patent position of biotechnology
                          companies generally is highly uncertain and involves
                          complex legal and factual questions. Although initial
                          approvals have been granted by the Patent and
                          Trademark Office with respect to some of our tests,
                          certain of our patent

                          applications may be rejected. Even when patents are
                          issued, the claims of any issued patents may not
                          provide meaningful protection for our technology or
                          products. Others may develop similar products which
                          test for susceptibility related to the same diseases
                          yet avoid infringing upon, or conflicting with, our
                          anticipated patents. In addition, there can be no
                          assurance that any patents issued to us will not be
                          challenged, and subsequently narrowed, invalidated or
                          circumvented.
 
                        - Technological Changes Resulting in Product
                          Obsolescence.  It is possible that our competitors
                          will develop technologies more effective than those
                          contained or used in our products. Our competitors
                          could develop new products which make our products
                          less competitive or obsolete.
 
                        - Limited Marketing or Sales Experience.  We have
                          limited experience in developing and commercially
                          marketing our genetic susceptibility testing services.

                                  RISK FACTORS
 
     The shares of Common Stock offered by this Prospectus are speculative and
involve a high degree of risk of loss. Prior to making an investment, you should
carefully read this entire Prospectus and consider the following risk and
speculative factors:
 
UNCERTAINTY OF MARKET ACCEPTANCE FOR GENETIC SUSCEPTIBILITY TESTS
 
   
     The commercial success of our genetic susceptibility tests and those that
we 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. We
expect to expend substantial financial resources to effectively promote the
benefits of our genetic susceptibility tests and those that we may develop. We
intend 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 we may develop will gain
market acceptance on a timely basis. If patients, dentists and physicians do not
accept our tests, or take a longer time to accept than we anticipate, then our
revenues and profit margins may be reduced and may result in losses. See
"Uncertainty of Insurance Reimbursement" at page 10.
    
 
NEW BUSINESS VENTURE
 
     The securities being offered by us are subject to the risks inherent in any
new business venture. Although we have operated as a contract research firm
since 1986, we have limited experience and a short history of operations with
respect to marketing and selling susceptibility tests or therapeutics. We have
had only minimal revenues related to the sale of our genetic susceptibility
testing services. With the exception of our periodontal susceptibility test, the
genetic susceptibility tests anticipated to be sold by us have not yet been
finally designed, developed, tested or marketed. Therefore, there can be no
assurance that we 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. Our business may also be affected significantly by economic
and market conditions over which we have no control. Consequently, an investment
in our Common Stock is highly speculative. We do not guarantee any return on an
investment in our Common Stock.
 
HISTORY OF OPERATING LOSSES; ACCUMULATED DEFICIT; UNCERTAINTY OF FUTURE
PROFITABILITY
 
   
     We incurred a net operating loss of $788,546 in fiscal year 1996. We
anticipate a net loss of approximately $4.0 million in 1997. As of September 30,
1997, our accumulated deficit was $3,913,577. Our losses have resulted
principally from expenses incurred in research and development and from selling,
general and administrative expenses. These expenses have exceeded our revenues.
We have yet to generate any significant revenues from the sale of our genetic
susceptibility testing services and there can be no assurance that we will be
able to generate significant revenues in the future. We expect our operating
losses to continue for the near future as our research and development, sales
and marketing activities and operations continue. Our ability to achieve
profitability depends on our ability to develop our sales and marketing capacity
and our ability to successfully market and sell our products and services. It is
uncertain when we will become profitable. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" at page 22.
    
 
INTENSE COMPETITION
 
     Research in the field of disease predisposing genes and genetic markers is
intense and highly competitive. Genetic research is characterized by rapid
technological change. Our competitors in the United States and abroad are
numerous and include, among others, major pharmaceutical and diagnostic
companies, specialized biotechnology firms, universities and other research
institutions (including those receiving funding from the Human Genome Project).
Many of our potential competitors have considerably greater financial,
technical, marketing and other resources than us. These greater resources may
allow our competitors to discover important genes or genetic markers before us.
If we, in conjunction with the Department of Molecular and Genetic Medicine at
the University of Sheffield, U.K., do not discover disease predisposing
 
                                        9
<PAGE>   14
 
   
genes or genetic markers associated with increased disease severity,
characterize their function, develop susceptibility tests and related
information services based on such discoveries, obtain regulatory and other
approvals, if needed, and launch such services or products before competitors,
then our revenues and earnings will be reduced or eliminated. In addition, any
of the susceptibility tests that we may develop, including our periodontal
susceptibility test, could be made obsolete by less expensive or more effective
tests or methods which may be developed in the future. We expect competition to
intensify in our industry as technical advances are made and become more widely
known. See "Uncertain Ability to Protect Proprietary Technology" at page 11,
"Competition" at page 41 and "Intellectual Property" at page 40.
    
 
DIFFICULTY OF DEVELOPING GENETIC SUSCEPTIBILITY TESTS
 
     It is uncertain whether we will be successful in developing and bringing to
market our current portfolio or future tests based on the genetic discoveries
made by us and our collaborators. Even when we discover 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 our company to cancel a program. Such delays,
reduced acceptance or cancellations would reduce revenues and may result in
losses.
 
UNCERTAINTY OF INSURANCE REIMBURSEMENT
 
     Our ability to successfully commercialize existing genetic susceptibility
tests and others that we 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 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, we initially expect 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 we 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 we formalized our
relationship by entering into an exclusive worldwide agreement (the "Master
Agreement"). Under the terms of the Master Agreement, we 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 us and Sheffield University agreed upon separately
under project agreements related to each test (each a "Project Agreement"). Our
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 our access to
future Sheffield University genetic discoveries that fall outside of the scope
of our existing Project Agreements.
 
                                       10
<PAGE>   15
 
     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 our 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 our 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, we would need to enter into additional collaborative
arrangements in order to continue to build a future pipeline of products.
 
     In the future we may, in order to facilitate the sale of our testing
services and/or products, enter into collaborative selling arrangements with one
or more other persons. It is uncertain whether we will be able to negotiate
acceptable collaborative arrangements in the future or that such collaborative
arrangements will be successful. If we are unable to identify collaborative
partners to sell certain of our services and/or products, we may be forced to
develop an internal sales force to market and sell our services and/or products
in markets where we are not intending on developing a direct selling presence.
Such a process would take more time and potentially cost more. As a result, our
revenues and earnings would be reduced. If we do enter into collaborative
selling arrangements, our success will depend upon the efforts of others and may
be beyond our control. Failure of any collaborative selling arrangement could
result in reduced revenues and possible losses.
 
UNCERTAIN ABILITY TO PROTECT PROPRIETARY TECHNOLOGY
 
     Our success will partly depend on our ability to obtain patent protection,
both in the United States and in other countries, for our products and services.
In addition, our success will also depend upon our ability to preserve our trade
secrets and to operate without infringing the proprietary rights of third
parties.
 
     We have ten (10) patent applications pending, including applications
covering each of our four genetic susceptibility tests. In June 1997, a Notice
of Allowance was issued by the United States Patent and Trademark Office with
respect to the patent applications for both our periodontal and osteoporosis
susceptibility tests. A Notice of Allowance is granted by the Patent and
Trademark Office, if, on examination of the application, the patent application
is found to be allowable. Thereafter a fee for issuing the patent is due within
three months from the date of the Notice of Allowance. When the issue fee is
paid, the patent issues as soon as possible after the date of payment, dependent
upon the backlog of patents at the Patent and Trademark Office. The patent is
then delivered or mailed on the day of its grant, or as soon thereafter as
possible. We paid the issue fee related to the application for the periodontal
susceptibility test on July 18, 1997 and for the osteoporosis susceptibility
test on September 8, 1997. While the issuance of these patents is likely, the
exact date of issuance is not known. It is rather unlikely, but possible, that
the United States Patent Trademark Commissioner could disallow the granting of
our patents at any time prior to the date of issuance. There can be no assurance
that our patent applications will ever be issued as patents or that the claims
of any issued patents will afford meaningful protection for our technology or
products. Further, others may develop similar products which test for
susceptibility related to some diseases yet avoid infringing upon, or
conflicting with, our anticipated patents. In addition, there can be no
assurance that any patents issued to us will not be challenged, and subsequently
narrowed, invalidated or circumvented.
 
     Our 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 our 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 us seeking
damages or seeking to enjoin us from testing, manufacturing or marketing our
products. Patent litigation is costly, and even if we prevail, the cost of such
litigation could have an adverse effect on us. If the other parties in any such
actions are successful, in addition to any liability for damages, we could be
required to cease the infringing activity or obtain a license. It is uncertain
whether
 
                                       11
<PAGE>   16
 
any license required would be available to us on acceptable terms, if at all.
Failure by us to obtain a license to any technology that we may require to
commercialize our products could have a material adverse effect on our 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 our filing of a patent application on such discovery,
may compromise our ability to obtain U.S. and foreign patent protection for the
discovery.
 
   
     We also rely upon unpatented proprietary technologies. We rely on
confidentiality agreements with our employees, consultants and collaborative
partners to protect such proprietary technology. There can be no assurance that
we can adequately protect our rights in such unpatented proprietary
technologies, that others will not independently develop substantially
equivalent proprietary information or techniques, or otherwise gain access to
our proprietary technologies or disclose such technologies. See "Intellectual
Property" at page 40.
    
 
     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 our or our 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 our testing services could also be adversely
affected by technological change. It is uncertain whether our competitors will
succeed in developing genetic susceptibility tests that circumvent or are more
effective than our technologies or services. Further, it is uncertain whether
such developments would render our or our collaborators' technology or services
less competitive or obsolete. Further, our 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 our company's ability to market our services
effectively. See "Uncertain Ability to Protect Proprietary Technology" at page
11, "Competition" at page 41 and "Intellectual Property" at page 40.
    
 
LIMITED MARKETING OR SALES EXPERIENCE
 
   
     Our business strategy is to provide genetic susceptibility testing services
aimed at common diseases that are treatable and preventable. The commercial
introduction of the periodontal susceptibility test at the beginning of October
1997 represents our first such effort. In preparation for the launch of the
periodontal susceptibility test, we have devoted substantial human and financial
resources to the establishment and staffing of a customer service support
facility and the building of a sales and marketing infrastructure. However, we
have limited experience in developing and commercially marketing susceptibility
testing services. It is uncertain whether our customer service support
facilities and sales and marketing program will achieve efficient, effective or
successful operations. Failure to successfully market such tests could reduce
our revenues and may result in losses. See "Competition" at page 41 and
"Government Regulation" at pages 12 and 44.
    
 
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 FDA or regulatory authority approval outside 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,
administered by the Health Care Financing Administration. In general, the
federal regulations governing approval of the laboratory facilities
 
                                       12
<PAGE>   17
 
and applicable state and local regulations governing the operation of clinical
laboratories apply to the laboratory but not to our company. However, changes in
the scope of the services offered by our company (e.g., establishing an in-house
clinical laboratory) would subject our company to applicable regulations.
Additionally, changes in existing regulations could require advance regulatory
approval of genetic susceptibility tests which may result in a substantial
curtailment or even prohibition of our activities without regulatory approval.
If our tests ever require regulatory approval, the costs of introduction will
increase and marketing and sales may be significantly delayed.
 
     Further, eighteen months ago the FDA proposed to regulate as medical
devices the "active ingredients" (known as "analyte specific reagents" or
"ASRs") of certain tests developed by, or in conjunction with, clinical
laboratories. Currently, a final rule has not been issued. The FDA has
specifically stated that it is not proposing a comprehensive regulatory scheme
over the final tests, but rather the active ingredients (ASRs) provided to the
laboratories that perform them. According to the FDA, any contemplated
additional controls (e.g. submission for Pre-Market Approval applications) over
the tests themselves would likely involve those tests which identify genes
associated with cancer or diseases associated with dementia. If the FDA requires
Pre-Market Approval of our genetic susceptibility test, our company may be
required to conduct pre-clinical studies, obtain an investigational device
exemption to conduct clinical tests, file a Pre-Market Approval application, and
obtain FDA approval. There can be no assurance such approval would be received
on a timely basis, if at all. The failure to receive such approval could require
us to develop alternative testing methods or utilize approved ASRs, which could
result in the delay or stop the use of such tests. Such a delay or termination
could result in reduced revenues or losses.
 
     Although our primary business is to develop genetic susceptibility testing
services, we may also develop or assist others to develop, drugs or other
treatments for the diseases related to our tests. The FDA and comparable
agencies in state and local jurisdictions and in foreign countries impose
substantial requirements upon the manufacturing and marketing of drug products
such as those potentially to be developed by our company or any partner. The
process of obtaining FDA and other required regulatory approvals is lengthy and
expensive. The time required for FDA approvals is uncertain and typically takes
a number of years, depending on the type, complexity and novelty of the product.
We may encounter significant delays or excessive costs in our efforts to secure
necessary approvals or licenses. Because certain of the products likely to
result from our research and development programs involve the application of new
technologies and will be based on new approaches, such products may be subject
to substantial additional review by various governmental regulatory authorities
and as a result, regulatory approvals may be obtained more slowly than for
products using more conventional technologies. There can be no assurance that
FDA approvals will be obtained in a timely manner, if at all. Any delay in
obtaining, or the failure to obtain, such approvals would adversely affect our
ability to generate product or product sales. Even if FDA approvals are
obtained, the marketing and manufacturing of drug products are subject to
continuing FDA and other regulatory review, and later discovery of previously
unknown problems with a product, manufacturer or facility may result in
restrictions on the product or manufacturer, including withdrawal of the product
from the market. Additional governmental regulations may be promulgated which
could delay regulatory approval of our potential products. We cannot predict the
impact of adverse governmental regulation which might arise from future
legislative or administrative action.
 
   
     We intend to generate product revenues from sales outside of the United
States. Distribution of our testing services or products outside the United
States may be subject to extensive government regulation. These regulations,
including the requirements for approvals or clearance to market, the time
required for regulatory review and the sanctions imposed for violations, vary by
country. It is uncertain whether we will obtain regulatory approvals in such
countries or that we will be required to incur significant costs in obtaining or
maintaining our foreign regulatory approvals. Failure to obtain necessary
regulatory approvals or any other failure to comply with regulatory requirements
could result in reduced revenues and earnings. See "Products and Services" at
page 27 and "Government Regulation" at page 44.

PRODUCT LIABILITY EXPOSURE
 
     Our business exposes us to potential liability risks inherent in the
testing and marketing of medical and dental related services or products. It is
uncertain whether liability claims will be asserted against us. We have product
and professional liability insurance which we believe provides coverage for the
testing and commercial introduction of our genetic susceptibility tests. It is
uncertain whether we will be able to maintain such insurance on acceptable
terms. Any insurance obtained may not provide adequate coverage against
potential liabilities. A liability claim, even one without merit, could result
in significant legal defense costs thereby increasing our expenses, lowering our
earnings and even resulting in losses.
 
DEPENDENCE ON CLINICAL LABORATORY
 
     The clinical laboratory operated by Baylor University currently performs
all of our genetics tests. Our company is not licensed as a clinical laboratory
and cannot perform genetic tests. Although we believe other clinical
laboratories are readily available if we cannot use Baylor University, the loss
of Baylor University may result in delays in the performance of genetic tests or
may increase the costs of performing genetic tests.
 
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 assessing a person's likelihood of developing a chronic
disease has also focused public and legislative attention on the need to protect
the privacy of genetic assessment 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 (Kassebaum-Kennedy 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
legislation indicates a trend to protect the privacy of patients while allowing
them to be screened for conditions which, can be prevented, reduced in severity
or cured. In the most extreme scenario, governmental authorities could, for
social or other purposes, limit the use of genetic testing or prohibit testing
for genetic susceptibility to certain conditions. For these reasons, we could
experience a delay or reduction in test acceptance. Such a delay or reduction
could reduce our revenues or result in losses.
 
     We are taking a proactive stance in the ethical arena. We have engaged Dr.
Philip Reilly, who is both an M.D. (certified specialist in clinical genetics)
and an attorney, to advise us in the area of genetic testing and its ethical,
legal and clinical utility ramifications. Additionally, we are currently
advising doctors who administer our genetic susceptibility tests to take special
efforts to maintain the confidentiality of the test results. Our 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, we 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 our tests and who subsequently send in a business reply
card seeking more information. See "Product Development" at page 36. 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. We intend to comply with
state law and regulations governing medical information privacy.
    
 
                                       14
<PAGE>   19
 
DEPENDENCE ON KEY PERSONNEL AND CONSULTANTS
 
     Because of the specialized scientific nature of our business, we are highly
dependent upon our ability to attract and retain qualified management,
scientific and technical personnel. Our company will also be dependent upon the
ability to hire qualified marketing and sales personnel. Competition for
scientific, marketing and sales personnel is intense. Loss of the services of
Mr. White, Dr. Kornman or Dr. Newman could adversely affect our research and
development programs and susceptibility testing service business and could
impede the achievement of our business objectives. We do not maintain key man
life insurance on any of our personnel.
 
CONTROL BY EXISTING SHAREHOLDERS
 
   
     Following completion of this offering, our directors, executive officers
and certain of their affiliates, will beneficially own approximately 56.14% of
our outstanding Common Stock. Accordingly, these shareholders, individually and
as a group, may be able to influence the outcome of shareholder votes, including
votes concerning the election of directors, the adoption or amendment of
provisions in our Amended and Restated Articles of Incorporation or Amended and
Restated By-Laws and the approval of certain mergers and other significant
corporate transactions, including a sale of substantially all of our assets.
Such control by existing shareholders could have the effect of delaying,
deferring or preventing a change in control. See "Principal Shareholders" at
page 53.
    
 
DILUTION; ABSENCE OF DIVIDENDS
 
   
     Purchasers in the offering will experience immediate and substantial
dilution in the net tangible book value of the Common Stock from the public
offering price. Additional dilution is likely to occur upon the exercise of any
options or warrants that we have granted. See "Dilution" at page 20. We have
never paid dividends and do not intend to pay any dividends in the foreseeable
future. See "Description of Securities" at page 54.
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Sales of substantial amounts of Common Stock in the public market following
this offering could lower the market price of the Common Stock. Of the 6,238,007
shares of Common Stock to be outstanding after this offering (assuming no
exercise of outstanding options, warrants or the overallotment option),
2,500,000 shares will be freely tradeable without restriction. Upon expiration
of the lock-up agreements entered into by the officers and directors of our
company, an additional 3,258,053 shares will become eligible for sale one year
from the closing of this offering, subject to the provisions of Rule 144. See
"Shares Eligible for Future Sale" at page 55. Of the remaining 479,954 shares of
Common Stock, 5,000 shares will be eligible for resale under Rule 144 following
this offering. The remaining 474,954 shares will have been held for less than
one year and will become eligible for sale at various dates as the one-year
holding period under Rule 144 is satisfied.
    
 
   
     In addition, we intend to file a registration statement on Form S-8 with
respect to the shares of Common Stock issuable upon exercise of options under
the 1996 Equity Incentive Plan (the "Plan"). The Plan authorizes the issuance of
options relating to up to 1,000,000 shares of Common Stock. Currently, there are
800,579 options that have been issued under the Plan which generally vest over
three years. See "1996 Equity Incentive Plan" at page 50. Upon filing of such
registration statement, the holders of such options may, subject to vesting
requirements, exercise and sell their shares immediately without restriction,
except affiliates who are subject to certain volume limitations and manner of
sale requirements of Rule 144. See "Shares Eligible for Future Sale" at page 55.
Holders of 356,545 warrants to purchase shares are entitled to certain
registration rights with respect to such shares. Upon registration, such shares
may be sold in the market without limitation. See "Registration Rights" at page
55. Sales of such shares may decrease the market price for our Common Stock. See
"Underwriting" at page 57.

IMPACT UPON FUTURE NET INCOME OR LOSS OF THE COMPANY BY CURRENT ACCOUNTING FOR
DEBT ISSUANCE COSTS
 
   
     From August 1, 1997 through October 6, 1997, the Company issued Bridge
Loans to investors in the aggregate amount of $1,780,000. In connection with the
issuance of these Bridge Loans, the Company also issued 356,545 warrants to
purchase the Company's Common Stock for $5.50 per share. The Company has
determined that an additional expense of $356,545 needs to be recognized in
connection with the issuance of these warrants. The $356,545 of additional
interest expense is currently being amortized over fourteen months, the terms of
the Bridge Loans. However, upon completion of the initial public offering, the
$1,780,000 Bridge Loans will be repaid and the unamortized amount will be
charged to earnings and will significantly impact the net income or loss of the
Company in the quarter in which the initial public offering is completed.
    
 
ARBITRARY OFFERING PRICE OF THE COMMON STOCK; POSSIBLE VOLATILITY OF COMMON
STOCK PRICE
 
   
     The initial public offering price of the Common Stock has been determined
by negotiations between our company and the Underwriter. The initial public
offering price bears no relationship to earnings, asset values, book value or
any other recognized criteria of value. See "Underwriting" at page 57.
    
 
     The market prices for securities of emerging health care companies have
been highly volatile. Announcements may have a significant impact on the market
price of the Common Stock. Such announcements may include biological or medical
discoveries, technological innovations or new commercial services by us or our
competitors, developments concerning proprietary rights, including patents and
litigation matters, regulatory developments in both the United States and
foreign countries, public concern as to the safety of new technologies, general
market conditions as well as quarterly fluctuations in our revenues and
financial results and other factors. The stock market has from time to time
experienced extreme price and volume fluctuations which have particularly
affected the market prices for emerging and biotechnology companies and which
have often been unrelated to the operating performance of such companies. These
broad market fluctuations may adversely affect the market price of our Common
Stock. In the past, following periods of volatility in the market price of a
company's stock, securities class action litigation has occurred against the
issuing company. Such litigation could result in substantial costs and a
diversion of management's attention and resources, which could have a material
adverse effect on our revenues and earnings. Any adverse determination in such
litigation could also subject us to significant liabilities.
 
EFFECT OF PREFERRED STOCK AND DIRECTOR REMOVAL PROVISIONS
 
     Our Board of Directors is authorized to issue up to 5,000,000 shares of
Preferred Stock and to determine the price, rights, preferences and privileges
of those shares without any further vote or action by our shareholders. The
rights of the holders of Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any shares of Preferred Stock that may
be issued in the future. While we have no present intention to issue shares of
Preferred Stock, such issuance, while providing desirable flexibility in
connection with possible acquisitions and other corporate purposes, could have
the effect of making it more difficult for a third party to acquire a majority
of our outstanding voting stock. In addition, such Preferred Stock may have
other rights, including economic rights, senior to the Common Stock. As a
result, the issuance of Preferred Stock could decrease the market value of the
Common Stock.
 
     Our Amended and Restated Articles of Incorporation provide that members of
the Board of Directors may be removed only for cause upon the affirmative vote
of holders of at least a majority of the shares of our outstanding capital stock
entitled to vote. Certain other provisions of our Amended and Restated Articles
of Incorporation could also have the effect of delaying or preventing changes of
control or in management. Such a delay or preventive effect could adversely
affect the price of our Common Stock.

                                  THE COMPANY
 
     Drs. Kenneth S. Kornman and Michael G. Newman founded the Company in 1986
to develop and introduce new methods, tools and technology for dental
practitioners that would better predict treatment outcomes in patients. We
derived our initial revenue primarily from contract research to pharmaceutical
companies and others. In early 1992, we expanded our contract research program
to include both medical and dental research. In 1994, we implemented an internal
product discovery program. We then used profits generated from our contract
research programs to fund our own product research and development.
 
   
     We originally operated under two separate Texas corporations, known as Oral
Science Systems and Oral Science Technologies. In August 1995, Oral Science
Systems was merged into Oral Science Technologies which changed its corporate
name to Medical Science Systems, Inc. ("MSS"). MSS continued to function as a
Subchapter "S" corporation until September 30, 1996, when it became a "C"
corporation. MSS' principal executive office is located at 4400 MacArthur
Boulevard, Suite 980, Newport Beach, California 92660, and may be reached by
telephone at (714) 440-9730. MSS maintains a website located at
http://www.medscience.com.

                                USE OF PROCEEDS
 
   
     If all 2,500,000 shares of Common Stock offered by this Prospectus are
sold, we will receive net proceeds of approximately $19,670,000 (assuming the
public offering price is $9.00, and assuming the over-allotment option is not
exercised). If the Underwriters exercise the over-allotment option, our company
would receive an additional $3,003,750. Net proceeds are determined after
deduction of all commissions, discounts and expenses paid to the Underwriters
(estimated to be $2,475,000) and after all expenses of the offering (estimated
to be $355,000).

(1) The proceeds of the Bridge Loans were applied and utilized in the following
    manner: $7,000 (cost of bridge financing, including legal expenses);
    $125,000 (initial public offering expenses); $600,000 (operating expenses,
    August and September 1997); $300,000 (operating expenses, October 1997); and
    $748,000 (remaining on balance as of November 12, 1997).
    
 
     The amount and timing of working capital expenditures may vary
significantly depending upon numerous factors, including the progress of our
research, discovery and development programs, the timing and costs involved in
obtaining regulatory approvals, the costs involved in filing, prosecuting and
enforcing patent claims, competing technological and market developments,
payments received under collaborative agreements, changes in collaborative
research relationships, the costs associated with potential commercialization of
our products, including the development of marketing and sales capabilities, the
cost and availability of third-party financing for capital expenditures and
administrative and legal expenses.
 
     We believe that our available cash and existing sources of funding,
together with the proceeds of this offering and interest earned thereon, will be
adequate to maintain our current and planned operations for at least the next 18
months.
 
   
     Until used, we intend to invest the net proceeds of this offering in
interest-bearing, investment-grade securities. While the net proceeds are so
invested, the interest earned by us on such proceeds will be limited by
available market rates. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" at page 22. We intend to invest and use
such proceeds so as not to be considered an "investment company" under the
Investment Company Act of 1940, as amended.

    $3.70 or $5.00 per share; (iii) 199,421 shares of Common Stock reserved for
    issuance pursuant to our 1996 Equity Incentive Plan; (iv) the exercise of

                                    DILUTION
 
     As of September 30, 1997, there were 3,738,007 shares of our Common Stock
outstanding, having a negative net tangible book value per share of
approximately $(0.46). Net tangible book value per share represents the amount
of our total tangible assets less our total liabilities, divided by the number
of shares of our Common Stock outstanding.
 
   
     After giving effect to the sale of the 2,500,000 shares of Common Stock
under this offering at a price of $9.00 per share and the application of the net
proceeds therefrom (but assuming none of the options or warrants are exercised),
there would be a total of 6,238,007 shares of our Common Stock outstanding with
a net tangible book value of approximately $2.88 per share. This would represent
an immediate increase in net tangible book value of $3.34 per share to existing
shareholders and an immediate dilution of $6.12 per share to new investors.
Dilution is determined by subtracting net tangible book value per share after
the offering from the amount paid by new investors per share of Common Stock.
The following table illustrates the per share dilution:

     The foregoing table assumes (i) no exercise of the Underwriters'

(iii) no exercise of the 356,545 Bridge Warrants, exercisable at $5.50 per
share; and (iv) no exercise of stock options outstanding after September 30,
1997. As of September 30, 1997, there were options outstanding to purchase a
total of 800,579 shares of Common Stock under our 1996 Equity Incentive Plan, at
a weighted average exercise price of $4.37 per share. To the extent that any of
the shares of Common Stock are issued on exercise of any of these warrants,
options or additional options granted after September 30, 1997, there will be
further dilution to new investors. See "Description of Securities" at page 54.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following discussion and analysis should be read in conjunction with
the Financial Statements and related Notes contained elsewhere in this
Prospectus. This Prospectus contains forward-looking statements which involve
risks and uncertainties. Our actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed in "Risk
Factors" at page 9.
    
 
OVERVIEW
 
     Since inception, we have devoted substantially all of our resources to
maintaining our research and development programs and supporting contract
research agreements. To date, we have received limited revenues from the sale of
our periodontal susceptibility test. Revenues received by us have historically
been payments pursuant to contract research agreements. For the fiscal year
ended December 31, 1996, we had a net loss of $789,000 and as of December 31,
1996 had a shareholder deficit of $700,000.
 
     We had two research contracts with Alpharma, Inc. ("Alpharma") for the
clinical investigation of Alpharma's proprietary periodontitis antibiotic
product. These contracts and the payments associated therewith ended in June
1996.
 
     We intend to enter into additional contract research agreements to assist
in the funding of our own internal research projects. There can be no assurance
that we will be able to enter into additional contract research agreements on
terms acceptable to us. We could incur losses for at least the next several
years, primarily due to expansion of our research and development programs,
increasing staffing costs and expansion of our facilities. Additionally, we
expect to incur substantial sales, marketing and other expenses in connection
with launching our genetic susceptibility testing business. We expect that
losses will fluctuate from quarter to quarter and that such fluctuations may be
substantial.
 
     We devoted significant resources during the last fiscal year to the beta
testing and validation of our genetic susceptibility test related to
periodontitis, as well as building our 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
personnel and the associated increase in use of test materials and commercial
laboratory charges. We also incurred increased development expenses during the
year related to work on developing our genetic susceptibility tests for
osteoporosis, coronary artery disease and diabetic retinopathy. We expect
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, 1996 increased $407,000 from the year ended December 31, 1995. The increase
was attributable to sales and marketing expenses related to the upcoming launch
of our periodontal susceptibility test and salaries and benefits paid to
existing and newly hired sales and marketing employees. We recently commercially
launched our periodontal susceptibility test on October 3, 1997. Additionally,
we expect that our general and administrative expenses will continue to increase
in support of our research and development efforts and the anticipated growth of
our genetic susceptibility testing business.
 
RESULTS OF OPERATIONS
 
     NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996.
 
   
     Revenues for the nine months ended September 30, 1997 decreased by
$1,753,000, from $1,905,000 for the nine months ended September 30, 1996 to
$152,000 for the same period in 1997, due to the decrease in contract research
agreements. In the summer of 1996, we changed our focus from providing
pharmaceutical companies clinical trial and research services pursuant to
contract research agreements to concentrating our resources on developing
genetic susceptibility tests. This change in focus resulted in a significant
decrease in revenue for the nine months ended September 30, 1997 compared to the
same period for 1996. Research and development expenses of $785,000 for the nine
months ended September 30, 1997 were comparable to the
    
 
                                       22
<PAGE>   27
 
   
$682,000 for the same period in 1996. The research and development expenses are
attributed to development expenses related to work on developing our genetic
susceptibility tests for periodontitis, osteoporosis, coronary artery disease
and diabetic retinopathy. The increase of $103,000 in research and development
is due to our focus on developing genetic susceptibility tests. Selling, general
and administrative expenses increased by $1,388,000 from $776,000 for the nine
months ended September 1996 to $2,164,000 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 our
periodontal susceptibility test.
    
 
   
     Interest income for the nine months ended September 30, 1997 decreased by
$6,000 primarily due to decreased funds available for investment. Interest
expense for the nine months ended September 30, 1997, amounted to $99,000, an
increase of $85,000 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 nine months ended September 30, 1996 was $97,000
compared to $3,042,000 for the nine months ended September 30, 1997. 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.
 
     YEARS ENDED DECEMBER 31, 1996 AND 1995.
 
     Revenues for the year ended December 31, 1996 increased by $46,000.
Research and development expenses increased to $958,000 for the year ended
December 31, 1996 from $582,000 for the year ended December 31, 1995. The
increase in research and development expenses is attributed to development
expenses during the period related to work on developing our genetic
susceptibility tests for periodontitis, osteoporosis, coronary artery disease
and diabetic retinopathy. Selling, general and administrative expenses increased
to $1,163,000 for the year ended December 31, 1996 from $756,000 for the year
ended December 31, 1995. The increase in 1996 was primarily due to the hiring of
additional personnel and costs related to the pre-commercial launch of our
periodontal susceptibility test.
 
     Interest income for the year ended December 31, 1996 increased to $9,000
from $0 for the prior year, due to the increased funds available for investment.
These funds were raised in our private placement of common stock in starting in
November 1996 and through our contract research agreements with various
companies. Interest expense for the year ended December 31,1996, amounting to
$34,000, was due entirely to a working capital line of credit and a long term
loan with Bank of America.
 
     The net income for the year ended December 31, 1995 was $150,000 compared
to a net loss of $789,000 for the year ended December 31, 1996. The difference
is a result of the increase in research and development expense, the increase in
selling, general and administrative expenses and the decrease in research
contract revenues.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     We have financed our operations from inception through contract research
revenues and more recently through sales of common stock and borrowings. During
1997 we have received $1,882,000 in net proceeds from private placements of our
Common Stock. We raised an additional $1,780,000 through a debt/warrant offering
from August 1, 1997 through October 6, 1997.
 
     We have 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 September 30, 1997, our borrowings under the term loans were $483,000 and
$185,000, respectively.
 
   
     As a result of the private placements of debt and equity securities and the
new loan agreements, our cash and cash equivalents has increased from $56,000 at
December 31, 1996 to $870,000 at September 30, 1997.
    
 
   
     During the nine months ended September our Company spent $35,000 on
furniture and equipment and $108,000 on patents.
    
 
                                       23
<PAGE>   28
 
     During the nine months ended September 30, 1997 and 1996, and the fiscal
years ended December 31, 1996 and 1995, our cash provided by (used in)
operations used in was $(2,469,000), $(23,000), $(442,000) and $112,000,
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 our genetic susceptibility tests.
 
   
     We expect to use a portion of the net proceeds of this offering for
expanding sales and marketing efforts, funding of clinical studies, increasing
production or commercialization capacity, customer service and funding research
and development, the repayment of the investor Bridge Loans, as well as for
working capital and general corporate purposes. A portion of the proceeds may
also be used for investments in or acquisitions of complementary businesses,
products or technologies. See "Use of Proceeds" at page 18.

GENERAL DESCRIPTION
 
     We provide genetic susceptibility testing services for common diseases that
are treatable and preventable. We have focused on four diseases initially:
periodontitis (gum disease), osteoporosis (bone disease), coronary artery
disease (heart disease) and diabetic retinopathy (blindness associated with
diabetes). Our 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 our genetic susceptibility tests to assess the risk involved
for individual patients and to adopt appropriate treatments or therapy,
including preventive measures. Our genetic tests will 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.
 
     Our 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. We believe
that this will contribute to a better quality of life, while directing
healthcare resources to individuals who derive the greatest benefit.
Accordingly, our mission is to improve patient care and treatment outcomes by
incorporating genetic information regarding disease susceptibility into overall
risk assessment and treatment planning.
 
SCIENTIFIC BACKGROUND
 
     Genetic Testing.  For many years it was well accepted that genetics
influenced much of our health and behavior. Scientists frequently noted that
certain diseases "ran in families." The clear genetic influence on disease was
only known, however, for a few uncommon or rare conditions such as Down's
Syndrome or Tay-Sachs Disease. Such conditions involve either a major
abnormality in a chromosome or a genetic defect that is strong enough by itself
to cause a clinical problem. Both types of genetic abnormalities are so powerful
that they are usually evident in childhood.
 
     Some diseases, such as Down's Syndrome, are essentially entirely genetic.
Others are essentially entirely environmental, such as an infected cut. The
purely genetic conditions tend to be rare, or at least uncommon. For example,
the defects in the gene associated with breast cancer are involved in only 5% to
10% of all breast cancers. Accordingly, 90% to 95% of all breast cancers are
caused by some other factor or factors.
 
     Most of the common chronic diseases that cause the greatest debilitation
and cost for adults are diseases in which genetics interact with other factors,
such as lifestyle or environmental challenges to the body. We refer to such
diseases as "multi-factorial" because numerous factors contribute to the disease
(Figure 1). For example, while it has been demonstrated that there is a genetic
influence on the susceptibility to periodontitis, research has also shown that
periodontitis is influenced by factors such as smoking and oral hygiene.

     In multi-factorial diseases the genetic influence is not due to a "genetic
defect" but a normal variation within the population. For example, for a
specific gene, 20% to 30% of the population may have a slight variation in the
genetic code that alters the function of that gene just enough under certain
environmental challenges that a specific disease is accelerated (Figure 1).
Since these variations are multiple forms of the same gene, they are called
genetic polymorphisms or genetic markers.
 
     If the genetic polymorphisms associated with a common disease can be
identified, it is possible to predict those at high risk for disease and alter
the individual's lifestyle or provide early medication to prevent clinical
disease. If the polymorphism can be shown to actually be involved functionally
in accelerating the disease, then that information may be used to develop
innovative new treatments or preventive agents.
 
     For example, it is well established that two proteins, interleukin-1
("IL-1") and tumor necrosis factor ("TNF") play a central role in many chronic
diseases that have inflammatory components. We have discovered specific genetic
variations that influence how much IL-1 and TNF are produced in the body. Our
findings in periodontal disease provide an example of how this works. Normally,
the body produces IL-1 and TNF in responses to a bacterial infection to help
activate the inflammatory and immune responses that will fight the infection.
This happens without producing any longlasting tissue damage. In a person where
a certain genetic variation exists, excessive levels of IL-1 or TNF are
produced. This causes an inflammatory response that may lead to tissue damage.
Our research revealed that individuals with two specific polymorphisms in the
IL-1 genes were predisposed to more severe periodontitis. Our periodontal
susceptibility test determines whether an individual has such a genetic
predisposition.
 
     In general, it may be said that the early detection of a predisposition to
genetic diseases presents the best opportunity for medical intervention. Early
genetic diagnosis may improve the prognosis for a patient through supervision
and early intervention before the clinically detectable disorder occurs.

     Genetic Susceptibility Test for Periodontal Disease (Patent Pending).
 
     DESCRIPTION OF PERIODONTAL DISEASE TEST. Our 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.
 
     Periodontitis results from a complex interplay of bacterial infection with
the patient which can often be modified through behavioral factors. The fact
that periodontal disease is both preventable and treatable makes predicting the
host response (or one's susceptibility to the development of periodontal
disease) "wanted information" for the patient and health care provider.
Periodontists have attempted for years to understand why patients with similar
plaque levels and oral bacterial profiles often show remarkably different
clinical characteristics. It is now possible to integrate genetics into overall
risk assessment so clinicians can identify that subset of patients who are
highly susceptible to rapid disease progression and severe periodontitis. This
discovery allows individual patients to be managed in a more targeted and
proactive way.

        reported by K. Kornman et. al, Journal of Clinical Periodontology,
        January 1997.
 
     Our 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 (Figure 2). 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 and show increased
bleeding on probing (Figure 3). 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. Since IL-1 in high concentrations is known to be
destructive to tissues, this may explain the more rapid progression of
periodontal disease experienced by patients with this specific IL-1 genotype
when faced with a bacterial challenge. Prevention or therapeutic 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.
 
   
     We have developed our periodontal susceptibility test and continue to be
governed by a project agreement between our company and Sheffield University.
See "Competitive Advantages" at page 42.
    
 
     A patent application related to the detection of genetic predisposition to
periodontal disease has been filed and assigned to us from Sheffield University,
Dr. Gordon Duff and Dr. Kenneth Kornman. We have received a Notice of Allowance
from the U.S. Patent and Trademark Office related to the patent's anticipated
issuance.

     MARKET FOR PERIODONTAL SUSCEPTIBILITY TEST. The American Academy of
Periodontology estimates that:
 
        "$5 billion was spent in 1990 to treat gingivitis and periodontal
        disease, more than $10 billion is spent annually for the replacement of
        teeth lost to periodontal disease, that 80% of all employed American
        adults have some stage of periodontal disease and that periodontal
        disease is the primary cause of tooth loss in adults 35 years and
        older."
 
     In general, population based studies indicate that gingivitis (that is,
mild gum disease) affects 50% of the adult population. Studies also show that
periodontitis affects between 30% to 35% of U.S. adults and increases with age
after 35. Many of the affected individuals have mild clinical disease, but it
appears that 20% of the adult population have a level of periodontitis which
requires professional treatment.
 
     The early identification of those individuals susceptible to severe
periodontal disease would allow for more aggressive prevention and treatment of
the disease. Early intervention is the key to preventing or stopping the
progression of the disease in order to minimize permanent loss of bone that
supports the teeth. Most periodontal disease is currently diagnosed only after
significant damage has already occurred. The patient is frequently referred to a
specialist if the patient does not respond to conventional cleaning therapy and
continues to experience substantial additional bone loss. The current dilemma is
the inability to differentiate between those patients likely to respond to the
normal conservative approaches such as scaling and root planing, oral hygiene
improvement and more regular dental visits, and those which will likely go
rapidly downhill despite customary therapy. Those who have periodontal disease
and are susceptible to the severe form of periodontitis need more aggressive
care such as more frequent monitoring and periodontal cleanings, earlier
treatment with drugs or even early surgical intervention in severe cases.
 
     Early identification of patients at high risk for periodontitis will allow
general practitioner dentists, as well as periodontists, to better focus
resources and confidently choose the most cost-effective therapy. Moreover, use
of our periodontal susceptibility test will allow payors to better monitor
resource utilization and to better design dental insurance plans.
 
     We commercially launched our periodontal susceptibility test on October 3,
1997.
 
     Genetic Susceptibility Test for Osteoporosis (Patent Pending).
 
     DESCRIPTION OF OSTEOPOROSIS SUSCEPTIBILITY TEST. The second genetic test we
are currently developing 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. We have 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.
 
                                       29
<PAGE>   34
 
     We have 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 (Figure 4).

                      file, Medical Science Systems, Inc.
 
     Our test provides data that will allow practitioners to practice preventive
medicine. Ideally, all females should be tested for this genetic trait by
adolescence so that they are encouraged to develop healthy lifestyles to attain
peak bone mass prior to the onset of menopause. These lifestyles include
avoiding smoking, increasing the intake of calcium, and participating in regular
weight-bearing exercise. Results of this test will also 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.
 
     A patent application related to the method of testing for genetic
predisposition to osteoporosis has been filed and assigned to Sheffield
University. Sheffield University, has in turn, granted to us an exclusive
worldwide license to utilize the underlying patent. Under the terms of our
Project Agreement with Sheffield University, upon our commercialization of the
osteoporosis susceptibility test, Sheffield University is obligated to assign
the patent to us in its entirety. The U.S. Patent and Trademark Office has
recently issued a Notice of Allowance with respect to the aforementioned patent.
 
     MARKET FOR OSTEOPOROSIS SUSCEPTIBILITY TEST. Twenty-eight million Americans
suffer from osteoporosis, of which 85% are women. Post-menopausal osteoporosis,
stemming from the loss of estrogen, affects more than one-half of all women over
65 years of age and has been detected in as many as 90% of women over age 75.
Osteoporosis is responsible for a majority of the 1.5 million bone fractures
each year, leading to disabilities costing more than $10 billion in medical,
social and nursing home costs. In 1991, one out of three
 
                                       30
<PAGE>   35
 
American women were 50 years of age or older. The "baby boomer" generation began
to enter this age group in 1996.
 
     In the past, a diagnosis of osteoporosis was made only after an elderly
individual had suffered a bone fracture. The current definition requires that
the individual has lost enough bone to put them at increased risk for fractures.
Since the strength of bones is largely determined by the mineral density of the
bones, an assessment of bone mineral density is currently the most reliable
method for determining whether one has osteoporosis. The diagnosis may therefore
be made by bone densitometry measurements that allow the calculation of the
density of bone relative to normal individuals. The key problem with this
approach is that it is directed at Those individuals who already have the
disease and have manifested symptoms. Although new therapies reverse some bone
loss, their primary benefit is in retarding future bone loss. Given that little
can be done to reverse damage that has already occurred, it appears that the
best management of osteoporosis will involve early detection and prevention.
 
     By identifying at-risk individuals before symptoms appear, the individual
can be counseled to make appropriate life style changes or institute other
treatments. For example, calcium supplements and exercise have been shown to be
valuable preventive factors if used during a critical early age window. Hormone
replacement therapy has also been used successfully to combat osteoporosis
occurring after menopause. Hormone replacement therapy may be of greatest
benefit if used early in the disease process before major bone loss has
occurred. New treatment alternatives for osteoporosis include a class of drugs
that has recently been approved called bisphosphonates. Didronel(TM), a
bisphosphonate manufactured by Procter and Gamble Pharmaceuticals, is available
in much of Europe. Fosamax(TM), another new bisphosphonate produced by Merck,
has recently received FDA approval and is now marketed in the U.S.
 
     Historically, it has been very difficult to reliably identify those women
who are at greater risk for developing severe osteoporosis. Although various
risk factors are strongly associated with osteoporosis, assessment of risk
factors in patients by means of questionnaires has not been a reliable means of
identifying women with low bone density. New urine or blood tests can detect
special chemical markers when the bone is actively being destroyed. However,
these chemical markers, like the bone density measurements, primarily provide
diagnostic information only after significant amounts of bone have been lost.
Unfortunately, the opportunity for increasing bone density by nutrition or
exercise occurs far before osteoporosis is detectable by such means.
 
     Since our marker is genetic, we may test patients at an early age and
identify their risk. This provides the opportunity for disease prevention in the
form of lifestyle changes early enough to make a difference. This test may also
be valuable in selecting patients for early drug intervention to stop
osteoporosis. Such drugs include earlier supplementation with estrogen or a
preemptive use of a bisphosphonate-class drug such as Fosamax(TM).
 
   
     We anticipate initiating marketing efforts related to a pre-commercial
phase for the osteoporosis susceptibility test in late 1997. See "Market
Development Strategy for Other Susceptibility Tests" at page 39. The full
commercial launch is anticipated to begin sometime in late 1998.
    
 
     Genetic Susceptibility Test for Coronary Artery Disease (Patent Pending).
 
     DESCRIPTION OF CAD TEST. The third genetic susceptibility test we are
developing 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. When an individual
has one copy of this specific genetic marker (i.e., is heterozygous) there is a
2.4 times greater chance of his developing coronary artery disease than the
general population. An individual who has two copies of the genetic marker
(i.e., is homozygous) has a 5.4 times greater chance of developing coronary
artery disease than the general population. It follows that being homozygous for
this particular genetic marker indicates a greater risk for coronary artery
disease than any other single risk factor (Figure 5).

     The availability of our 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 us an
exclusive worldwide license to utilize the underlying patent. Under the terms of
our Project Agreement with Sheffield University, upon our commercialization of
the CAD test, Sheffield University is obligated to assign the patent to us in
its entirety.
 
     MARKET FOR CAD TEST. More than one in four Americans, or about 60 million,
have some form of cardiovascular disease. Cardiovascular diseases kill nearly
one million Americans every year -- more than all forms of cancer (about
500,000), accidents (about 85,000), and AIDS (about 38,000) combined. Since
1900, cardiovascular disease has been the number one cause of death in the U.S.
every year except 1918 (when there was a world-wide flu epidemic). If all forms
of cardiovascular disease were eliminated, life expectancy would rise by 7.78
years.
 
     Atherosclerosis (or arteriosclerosis) refers to the progressive blockage of
arteries by plaque accumulation. Atherosclerosis is the principle cause of heart
attack, stroke and gangrene of the extremities. It is responsible for 50% of all
deaths in the U.S., Europe and Japan.
 
     If atherosclerosis occurs in the arteries that supply blood to the heart,
then the disease is often referred to as coronary artery disease ("CAD"). CAD
results in heart attacks (myocardial infarctions) due to damage to the heart
muscle when blood supply (and therefore oxygen) is cut off and heart muscle
cells die. Approximately 13.5 million Americans suffer from coronary artery
disease, and approximately half a million Americans die each year from this
disease.
 
     Although many theories exist, the causes and mechanisms of this build-up
are not completely understood. Because of this lack of understanding,
prediction, diagnosis, and treatment of atherosclerosis has centered on the
development of a set of risk factors that help to identify those individuals who
are most at risk. The primary approach to treatment for atherosclerosis, once
diagnosed, centers on controlling these risk factors.
 
                                       32
<PAGE>   37
 
     Unfortunately, many of the classic risk factors, such as smoking, high
cholesterol levels, and high blood pressure, only account for about half of the
incidence of CAD. Because CAD is the leading cause of death among people in the
U.S., a tremendous amount of research over the past four decades has been
directed at CAD. Initially, serum lipids (e.g., triglycerides and total
cholesterol) were linked with CAD during the 1940s and 1950s These observations
have been refined to focus on high and low density lipoproteins (i.e., "HDLs"
and "LDLs") as potential factors in the cause of the disease and as potential
markers of the disease.
 
     Preventive treatment, including lifestyle changes and drug therapy, is
directed primarily at reducing the risk factors. Treatment strategies usually
involve coronary artery by-pass surgery or angioplasty (i.e., expansion of the
blood vessel), both of which only treat the result and not the root cause(s) of
the disease. Though an increasingly large number of risk factors have been
identified, they still only account for slightly over half of the cases of
atherosclerosis.
 
     The genetic susceptibility test that we are developing may offer a
potential solution to this dilemma. The CAD test is based on a genetic marker
that is associated with an increased susceptibility to coronary artery disease
that substantially exceeded the increased risk of other commonly associated
factors, such as smoking or high cholesterol.
 
   
     We anticipate initiating marketing efforts related to a pre-commercial
phase for the CAD test in late 1998. See "Market Development Strategy for Other
Susceptibility Tests" at page 39. The full commercial launch is anticipated to
begin in 1999.
    
 
     Genetic Susceptibility Test for Retinopathy in Diabetics (Patent Pending).
 
     DESCRIPTION OF THE DIABETIC RETINOPATHY TEST. The fourth genetic
susceptibility test we are developing 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 data from our first clinical trial involving over
500 diabetics is shown below (Figure 6). Of the individuals who did not have the
specific genetic marker (genotype negative), approximately 10% developed
sight-threatening retinopathy. The risk for this group remained low and
relatively constant for many years. For genotype positive individuals, however,
the risk continued to increase dramatically until nearly 50% ultimately
developed sight-threatening diabetic retinopathy.

     Sight-threatening diabetic retinopathy refers to diabetic complications
affecting the retina that predictably lead to severe loss of vision. Retinal
disease is one of numerous problems related to diabetes. Retinal disease is
primarily the result of the disruption of small blood vessels in the retina due
to: (i) capillary leakage; and/or (ii) destruction or obstruction of capillaries
causing damage to the tissues of the retina and the uncontrolled growth of new
blood vessels. Such retinal changes are a leading cause of blindness in the
western world.
 
     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 us
an exclusive, worldwide license to utilize the underlying patent. Under the
terms of our Project Agreement with Sheffield University, upon our
commercialization of the diabetic retinopathy susceptibility test, Sheffield
University is obligated to assign the patent to us in its entirety.
 
     MARKET FOR DIABETIC RETINOPATHY TEST. In the United States there are
approximately 16 million people suffering from diabetes mellitus (or are
diabetic). It is estimated that only half of this number have been diagnosed.
There are two general categories of diabetes mellitus. Type I diabetes, or
insulin-dependent diabetes mellitus, generally appears in patients under 20
years of age and is marked by severe insulin deficiency. Type I diabetes is
generally detected at its onset and requires insulin treatment to control. Type
II diabetes, or non-insulindependent diabetes mellitus, emerges in patients over
20, may remain undetected for years, and is marked by insulin resistance and an
insulin deficiency. Dietary changes may be able to control Type II diabetes,
however, insulin supplements (that is, injections) are often required. Ninety
percent of all diabetics have Type II diabetes.
 
     Patients with either form of diabetes mellitus are at risk of developing
complications such as problems with their nervous system, kidneys, vision and
heart. Studies have shown that the duration of diabetes is
 
                                       34
<PAGE>   39
 
associated with the increasing incidence of diabetic complications. Accordingly,
the longer an individual has diabetes, the greater his or her chances of
developing complications. These complications are a major clinical burden in
diabetes, but the origination and development of the disease are not well
understood.
 
     Diabetic retinopathy is one of the most common complications of diabetes.
It is the fourth leading cause of legal blindness in the U.S. and the leading
cause of blindness in people ages 20 to 74. Each year 15,000 to 39,000 people
lose their sight from diabetic retinopathy. Early detection of retinopathy is
critical to the prevention of vision loss. The early stage of this disease is
known as nonproliferative retinopathy. Nonproliferative retinopathy is somewhat
difficult to detect but responds well to treatment. Nonproliferative
retinopathy, if untreated, can deteriorate with a resultant loss of vision.
Although treatment may arrest the condition, it will not restore lost vision.
 
     Proliferative retinopathy is the final state of the disease. At this point,
the disease involves the production or growth of new tissue in and around the
retina. These types of growths can lead to serious vision loss including
blindness. Satisfactory treatment is difficult in advanced proliferative
retinopathy. Surgical procedures used at this stage will themselves result in a
loss of patient vision four percent of the time. Clearly, early treatment of
diabetic retinopathy is desirable.
 
     We have 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.
 
   
     Confirmatory clinical studies of the diabetic retinopathy susceptibility
test are scheduled for completion in mid-1998. We anticipate initiating
marketing efforts related to a pre-commercial phase for the diabetic retinopathy
susceptibility test sometime in 1998. See "Market Development Strategy for Other
Susceptibility Tests" at page 39. The full commercial launch is anticipated to
begin sometime in 1999.
    
 
     Testing Procedure.  Each of our four genetic susceptibility tests will
require that the following single procedure be utilized. To conduct a genetic
susceptibility test, the doctor will draw a blood sample and submit it to our
customer service department. We will log in the sample and submit sample batches
to the testing laboratory. The laboratory will perform the test following our
specific protocol and inform us of the results. We, in turn, will advise 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, our billing
service (which we presently "outsource") 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.
 
     We are currently using Baylor University as our commercial laboratory. We
will continue to use one or more sophisticated, certified, and fully validated
laboratories, such as the Baylor facility, capable of providing consistent and
high quality analysis. Customer service is handled via our toll free "888"
numbers by our own staff who are knowledgeable about our 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, we conduct three categories of clinical trials in
conjunction with our 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. The

     Following confirmatory studies, additional trials are completed on larger
populations to help develop broad scientific evidence supporting the clinical
utility of each of our 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 our current four genetic susceptibility tests,
we have on-going research to continue to identify other genetic markers that
appear to be associated with certain other common diseases. We plan on filing
additional patent applications to cover these discoveries. It is our intent to
bring these discoveries to market in the form of additional genetic
susceptibility tests. We have also come upon certain genetic markers that might
be likely candidates to serve as therapeutic targets -- or in other words, be
susceptible to influence by drug agents. We are considering certain
collaborative long term relationships with pharmaceutical companies as a method
to provide for either the licensing of our discoveries or to assist in the
research and development of future products.
 
   
     There may be additional applications of either our testing services or the
underlying technology that we use to develop and support our genetic testing
services. We will seek to exploit opportunities to develop such additional
applications in conjunction with other companies so long as our company's focus
remains on genetic susceptibility testing. For example, we have recently granted
a worldwide, nonexclusive, nontransferable license to Digisphere, LLC to market
customized versions of our computer modeling technology to pharmaceutical
companies. Previously, we had only used our computer modeling technology for the
internal development of our genetic testing services. On August 1, 1997,
Digisphere, LLC was formed, representing a joint venture between our company and
Nelson Communications Inc. ("NCI"), one of the largest providers of health care
marketing services to pharmaceutical companies in the United States. See
"Transactions with Directors and Executive Officers" at page 52. Ownership of
Digisphere, LLC is divided approximately equally between our 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 our 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 our tests and who subsequently send in a
business reply card seeking more information. In both aspects of the joint
venture, our company will be acting as the technology/information partner and
NCI will be functioning as the marketing partner. As of September 30, 1997, we
have not received any revenues from this joint venture.
    
 
MARKET AND SELLING STRATEGIES
 
     General Strategy. Our strategy is to build a commercial operation based on
the delivery of our genetic susceptibility testing services on a worldwide
basis. Our testing services are aimed at multi-factorial diseases which are
treatable and preventable. Our strategy assumes that genetic tests revealing
susceptibility to preventable diseases will ultimately be highly valued by the
public, by clinicians involved in prevention and
 
                                       36
<PAGE>   41
 
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.
 
     We intend to utilize a sales and marketing approach which will aim to
improve patient care and treatment outcomes by incorporating genetic information
regarding disease susceptibility into overall risk assessment and treatment
planning. We hope 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. We
will seek to influence attitudes and mindsets through clearly articulating the
benefit for our customers and adopting a missionary sales approach in
partnership with crusaders in the field. Emphasis will be placed on building
strong relationships with key decision-makers and educators who will work with
us 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.
 
     Our initial goal will be to establish genetic tests such as our periodontal
susceptibility test into overall risk assessment and treatment planning for
patients. Ultimately, we envision 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.
 
  Market Strategy for Specific Tests.
 
     MARKET STRATEGY FOR PERIODONTAL SUSCEPTIBILITY TEST. We plan to develop the
worldwide market for our periodontal susceptibility test directly through a
number of centrally-driven tactics and thereby establish an environment in which
locally appropriate, focused selling efforts will be most likely to succeed. The
worldwide market will be segmented according to geography and customer groups,
with appropriate emphasis being given to specific segments as the business
grows. Wherever possible, we will initially sell our periodontal susceptibility
test directly, anticipating that once demand has been created we may elect to
work in partnership with other selling organizations that offer significantly
greater access to the market and/or a better competitive position.
 
     GEOGRAPHIC SEGMENTATION PLAN. Initial emphasis will be placed on sales of
our periodontal susceptibility test in North America. North America represents
at least half of the worldwide opportunity for our periodontal susceptibility
test. We intend to market directly in the U.S. and Canada, focusing on specific
customer segments as outlined below. In a parallel effort, we will also begin to
develop a sales program in Europe, in partnership with local sales organizations
familiar with the periodontal market. Emphasis will be placed on Italy, since
momentum and a customer base have already been established during our
pre-commercial phase. In the meantime, European customers who want access to our
periodontal susceptibility test are being serviced directly out of the U.S. The
same is true for Asia and South America. It is anticipated that partners will be
sought for sales efforts in these regions as well.
 
     CUSTOMER SEGMENTATION PLAN. There are several potential customers for our
periodontal susceptibility test who need to be targeted in a specific order and
with appropriate emphasis over time. Our study of the value-chain involved in
making or influencing a purchasing decision for our periodontal susceptibility
test revealed that some of the key players involved include: specialists
(primarily periodontists), general dentists, hygienists, reimbursement groups
(i.e., insurance companies, managed care organizations, etc.) and, of course,
the individuals (and their families) who are being tested. The degree to which
each of these groups embrace our periodontal susceptibility test will be
influenced by how others in the value-chain view the value of the information.
For example, initial feedback indicates that patients will be strongly
influenced by their doctors. Whereas, generalists may be influenced by how
specialists view the value of the test. Managed care organizations are likely to
be influenced by how attractive the test is to their current or potential
members. The influence diagram for the decision to purchase the test reveals a
high degree of interdependence between all of the groups. For this reason, it is
critical to develop the market in the right order and with the appropriate
selling message for the specific group being targeted. It is important not to
skip a step in the process or believe that, just because resistance to change in
a specific segment may be great, such segment may be ignored. The initial
segmentation plan we have developed will allow us to focus resources on the
group most likely to generate early sales growth, while at the same time
ensuring long-term sustainability and opportunity
 
                                       37
<PAGE>   42
 
for growth. In light of the foregoing, we will be targeting four customer
groups: (i) Periodontists/ periodontally-oriented GPs; (ii) General
Practitioners; (iii) Managed Care/Buying Groups; and (iv) Oral Care Companies
with Dental Research Programs.
 
     Periodontist/Periodontally-oriented GPs. During the launch period and early
adoption phase, emphasis will be placed on this segment in both North America
and Europe. From a market development standpoint, we recognize that it is
critical that our periodontal susceptibility test be understood and accepted by
"periodontists" for it to gain broad acceptance in the other segments.
 
     Relationships with opinion leaders and professional organizations are
already well established in this segment. Key opinion leaders have their own
data to present, which can be further supported with educational materials that
we have developed. Speakers will be engaged who can interpret the scientific
message and translate the breakthrough and effectively convey its clinical value
to others. Our goal is to be highly visible at major periodontal meetings
(international, national and "large" regional) the first year, with educational
information on our periodontal susceptibility test either incorporated into the
main program, or as part of an associated continuing education program wherever
possible. Our periodontal susceptibility test was recently featured at the last
general session of the American Academy of Periodontology meeting in October
1997.
 
     From a selling standpoint, periodontists can be reached with a relatively
small organization through attending their major meetings and sending targeted
mail/fax communications. We initially expect periodontists to be our major
source of revenue transitioning to dental general practitioners ("GPs") over the
course of the first year.
 
     We will seek to convince/motivate periodontists, in addition to testing
their own patients, to take the "genetic susceptibility testing/risk assessment
message" to referring GPs, and in some cases, directly to patients to help build
their practices. As such, we see periodontists as important multipliers and an
integral part of the "selling effort." Support materials, such as updated
referral slide shows and general dentist's brochures, patient brochures,
"informatics" and press release packets, are already being provided to help
periodontists to be more effective in this role.
 
     General Practitioners. We intend on developing this segment in a parallel
manner, with emphasis switching from periodontists to GPs as the business grows.
From a market development standpoint, we are working closely with leaders in the
American Dental Association to help them understand the benefits of our
periodontal susceptibility test to GPs, and to motivate then to educate their
membership. Our periodontal susceptibility test is already scheduled to be
presented at the American Dental Association's major fall meeting in Washington,
D.C., where the test will also be included in an exhibit on dental innovations
at the Smithsonian. Emphasis will be placed on translating the clinical value as
it relates to a general practice, with appropriate opinion leaders from their
own "camps" being identified for this purpose. GPs will be the target of mass
mailings and advertising campaigns to increase brand recognition for our
periodontal susceptibility test. In addition, we will seek to use periodontists
as "advocates" to reach their GP referral base. As the need for additional sales
activities within this segment grows, we will evaluate using a "co-marketing"
arrangement with a large GP-oriented sales organization.
 
     Managed Care/Buying Groups. Initially, we expect most genetic tests to be
paid for by the consumer, not insurance companies or other payors. Our
contracted billing service will directly bill the patient who has utilized the
test. We realize, however, that successful commercialization of our products and
services may depend in part upon the availability of reimbursement or funding
from third-party health care payors such as federal and state governmental
agencies, private insurance plans and health maintenance organizations. Thus, In
the longer term, we intend to target this managed care/buying group segment by
building a sales and marketing organization aimed at understanding the value of
genetic testing and risk assessment to large buying groups (including managed
care organizations of all forms and governments in some countries) and "selling"
through negotiating contracts with the decision makers (and gate keepers). This
is clearly the trend in organized healthcare and presents an opportunity for
susceptibility tests such our periodontal susceptibility test. As we grow, this
capability should also generalize to other genetic tests. From a market
development standpoint, we intend to better understand the needs of this
segment, and tailor claim support
 
                                       38

studies/educational activities to satisfy these needs. Our periodontal
susceptibility test is already scheduled to be featured at the next meeting of
the National Association of Dental Plans.
 
     Oral Care Companies with Dental Research Programs. An additional segment
that we intend to target involves companies with clinical research programs. We
have already sold some of our periodontal susceptibility tests to companies that
are interested in having patients in their clinical studies genotyped. Due to
the clear benefit of including this information in large clinical studies and
our strong preexisting relationships with many of the companies in this segment,
we view this as an opportunity to generate additional sales during the first
year with a limited selling effort. However, there can be no assurance that
future sales will be effected or that such sales will result in net income.
 
     Public Awareness/PR Plan. Initially most of our sales and marketing effort
aimed at the general public will be indirect, primarily in the form of brochures
and other tools that a doctor can use to explain the tests and their value to
patients. We have initiated some public relations activities in order to
increase public awareness of our specific tests and genetic susceptibility
testing more generally through the popular media. For example, with our
periodontal susceptibility test, we have initiated some publications in
cooperation with a professional organization known as the American Association
of Periodontology, which has its own vested interest in increasing public
awareness about the disease and featuring significant discoveries that help
validate the importance of the profession. We will begin to use PR in
coordination with our other selling efforts aimed at each customer segment we
approach. With the commercial introduction of the periodontal susceptibility
test at the American Academy of Periodontology meeting in October 1997, we began
a campaign aimed at reaching the periodontal and general dentists. Ultimately,
we plan on marketing directly to the public in order to create consumer demand
for our tests.
 
     Educational and Promotional Materials. As with any change of behavior
product, we anticipate the sales and promotional effort for our genetic
susceptibility test to be highly education-intensive and are planning to develop
several materials to support this effort. In addition, some promotional
materials will be developed that are primarily aimed at increasing
brand/logo/company recognition and creating a "high tech/ high value" image for
ourselves.
 
     Market Development Strategy for Other Susceptibility Tests. We are also
preparing market development plans to implement the "pre-commercial phase" for
our osteoporosis tests. We intend to implement a similar strategy as is
currently being utilized with our periodontal susceptibility test. We will
initially involve the current academic and research "thought leaders" in the
development and verification of our tests results and clinical utility. We will
then develop a speaker circuit where these thought leaders will begin to convey
the clinical utility and importance of our tests to specialists within each
testing area (e.g., cardiologist for the CAD test). As the thought leaders begin
to reach and influence the specialists we will then begin to target generalists,
who presumably will be or have been influenced by the specialists. At this point
direct marketing can be introduced to complete the progression, resulting in
consumer demand. This segmentation strategy has been proven to be effective with
other medical devices and is already being implemented with respect to our
periodontal susceptibility test.
 
SELLING METHODS
 
     Direct Sales. We plan to build demand for our susceptibility tests using a
small direct consultative sales organization specializing in genetic testing,
risk assessment and change of behavior. We do 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, we will consider
"co-marketing" or other business arrangements with companies with a large sales
organization in the field. Our 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, we will focus on sales partner
support and trade/professional association meetings. We will thereafter continue
to seek to establish corporate partnerships which will produce revenues,
credibility and a market presence for our other services and products.
 
     Professional and Industry Meetings/Trade Associations. Initially, we will
be present and market our products and services at all national and selected
regional associations and meetings where a genetic
 
                                       39
<PAGE>   44
 
susceptibility test has applicability to the professionals in attendance. Over
time, we anticipate our partners playing an increasingly important role in the
specific disease markets where our tests are used.
 
INTELLECTUAL PROPERTY
 
     Our commercial success will be dependent in part on our 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 us and Sheffield University. We
have ten patent applications pending, including applications covering each of
our four genetic susceptibility tests. In June 1997, a Notice of Allowance was
issued by the United States Patent and Trademark Office with respect to both our
periodontal and osteoporosis susceptibility tests. A Notice of Allowance is
granted by the Patent and Trademark Office, if, on examination of the
application, the patent application is found to be allowable. Thereafter a fee
for issuing the patent is due within three months from the date of the Notice of
Allowance. When the issue fee is paid, the patent issues as soon as possible
after the date of payment, dependent upon the backlog of patents at the Patent
and Trademark Office. The patent is then delivered or mailed on the day of its
grant, or as soon thereafter as possible. We paid the issue fee related to the
application for the periodontal susceptibility test on July 18, 1997 and for the
osteoporosis susceptibility test on September 8, 1997. While the issuance of
these patents is likely, the exact date of issuance is not known. It is rather
unlikely, but possible, that the United States Patent Trademark Commissioner
could disallow the granting of our patents at any time prior to the date of
issuance. We have filed and will continue to file foreign counterparts of our
U.S. applications within the appropriate time frames. Where we have originally
filed in another country, we plan 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.
 
     We own the patent application covering the genetic marker related to our
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 us 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 our Project Agreements with Sheffield University,
upon the commercialization of each test, Sheffield University is obligated to
assign the patent to us in its entirety.
 
   
     We have filed three patents related to our computer modeling software
technology, two of which are still pending and one of which has issued. We are
continuing to identify and develop applications related to additional genetic
markers. We have also applied for trademark protection for the name of our
periodontal susceptibility test. Our proprietary technology is subject to
numerous risks. See "Uncertain Ability to Protect Proprietary Technology" at
page 11.
    
 
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 (Kassebaum-Kennedy 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
 
                                       40
<PAGE>   45
 
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.
 
     We have attempted to take a proactive stance in the ethical arena. We have
engaged Dr. Philip Reilly, who is both an M.D. (board certified specialist in
clinical genetics) and an attorney to advise us in the area of genetic testing
and its ethical, legal and clinical utility ramifications. Additionally, we are
currently advising doctors who administer our genetic susceptibility tests to
take special efforts to maintain the confidentiality of the test results. Our
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, we 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 our tests and who subsequently send in a business reply
card seeking more information. See "Product Development" at page 36. 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. We intend 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, companies other than ours do exist 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"), Genome Therapeutics Corp. ("GTC") and Sequana Therapeutics, Inc.
("Sequana"). Both GTC and Sequana have announced that they have 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 our 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 our competitors receive
data and funding from the Human Genome Project at no cost to them, they may have
a competitive advantage over our company.
 
     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, our company's primary
business focus is developing and commercializing genetic susceptibility tests
for common diseases, with only an ancillary drug discovery program. Factors
which further differentiate us from other companies are discussed below in
"Competitive Advantages" at page 42.
    
 
                                       41
<PAGE>   46
 
COMPETITIVE ADVANTAGES
 
   
     Other companies have entered the market for genetic testing as medical
research has increasingly recognized the advantages provided by early detection
of genetic predisposition. Although many of these competitors have greater
financial and other resources than us (see "Competition" at page 41), we believe
that our company has many competitive advantages, including:
    
 
        (1) Alliance with The University of Sheffield, U.K. Our efforts in the
     genetic discovery and development process are complemented by a strategic
     alliance with the Section of Molecular Medicine at The University of
     Sheffield, U.K. Sheffield University is one of the world's leaders in
     genetic aspects of common diseases with an inflammatory component.
     Sheffield University's research is targeted around identifying and
     discovering genes and genetic markers which appear to correlate with a
     patient's susceptibility to common diseases.
 
        Our relationship with Sheffield University offers another significant
     advantage over our competitors in reducing the cost of genetics research.
     The gene discovery process uses and generates vast amounts of information.
     Such research is time consuming, costly, heavily dependent upon advanced
     computer technology and unpredictable. Sheffield University has an
     integrated genetics program consisting of approximately 46 M.D. and Ph.D.
     scientists and researchers focusing on molecular genetics. Sheffield
     University performs gene-identifying research for us, thereby reducing our
     costs and allowing us to focus our attention on developing and
     commercializing known genetic markers. Many of our competitors' primary
     focus and capital is spent on performing gene-identifying research.
 
   
        In exchange for Sheffield University's providing us with research and
     discoveries, the company has agreed to pay Sheffield University a share of
     the resultant net profits, with the percentage of net profits for our
     company and Sheffield University to be agreed upon separately under project
     agreements related to each test (each a "Project Agreement"). Pursuant to
     such Project Agreements, our share of the net profits ranges from 50% to
     67%. See "Reliance on Collaborative Partners" at page 10. Net profits will
     be paid out to Sheffield University only after we have recovered the cost
     of goods sold, all marketing and sales costs and all operational costs
     related to each of the separate tests.
    
 
        (2) Identified Genetic Markers. While many of our competitors are
     currently seeking to identify diseaserelated genes, we have already
     identified four genetic markers that indicate a patient's genetic
     predisposition to certain diseases. Additionally, we are continuing to
     identify other genetic markers and intend to file patent applications
     related to the same.
 
        (3) Focus on Diseases that are Treatable and Preventable. We are one of
     the few companies that we know of that is focusing on genetic
     susceptibility testing services for diseases that are treatable and
     preventable. Most of our competitors have not focused on
     treatable/preventable diseases but have instead focused on drug development
     with a secondary emphasis on genetic testing. Other companies, such as
     Myriad and OncorMed are developing tests for breast cancer for which there
     is no known preventive treatment (except mastectomy). The value of this
     information is, as a result, often times "unwanted" by the patient. Our
     tests, on the other hand, when used in overall risk assessment, provide
     doctors and patients with information regarding a patient's risk for
     developing a potential future disease. Since the disease is treatable and
     preventable, this information is "wanted." Doctors and patients may use
     this wanted information to take preventive measures to slow down or avoid
     disease progression and develop treatment plans based on a patient's future
     risk for disease progression.
 
        (4) Focus on Developing and Commercializing Genetic Susceptibility
     Testing Services. Our company's primary business focus is to develop and
     commercialize genetic susceptibility testing services. We are committed to
     becoming one of the world's leaders in marketing and selling genetic
     susceptibility tests. We believe that broad market acceptance of genetic
     susceptibility testing, and any particular test, can be achieved only by
     educating consumers and professionals about the benefits of genetic testing
     and demonstrating how genetic testing can improve patient risk assessment
     and treatment. In order to commercialize our own products and prepare the
     markets we are entering, we have built and continue to expand a team with
     significant experience in the commercialization process and marketing high
 
                                       42
<PAGE>   47
 
   
     technology medical and dental products which require a change of behavior.
     We have developed a focused marketing and sales strategy for our initial
     product that includes segmentation, thought leader development, educational
     marketing and consultative selling. See "Market and Selling Strategies" at
     page 36.
    
 
        (5) First to Market with a Genetic Susceptibility Test for a Disease
     That is Treatable and Preventable. We are the only company that we know of
     that has brought to market a test (our periodontal susceptibility test)
     that identifies a genetic marker which indicates a greater susceptibility
     to a disease which is treatable and preventable. As a result, we believe
     that we are well-positioned to become a market leader in the periodontal
     market and potentially in each of the other areas in which we have
     developed or are developing tests.
 
        (6) Computer Modeling Technology. We have developed a computer modeling
     technology that simulates the biology of specific diseases. These
     simulations include basic genetic, cellular and subcellular interactions,
     as well as systems-level information about the clinical symptoms involved
     in the disease process. They allow a comprehensive integration of
     gene-expression data, basic biochemistry, and cell biology such that
     disease-associated genetic findings may be linked to the clinical outcomes.
     These simulations give us a competitive advantage by allowing us to more
     accurately and efficiently:
 
           (i) evaluate the combined effects of genetic markers and other risk
        factors in order to establish risk assessment;
 
           (ii) link risk assessment profiles to treatment regimes;
 
           (iii) identify new candidate genes or genetic markers; and
 
           (iv) design clinical trials more effectively.
 
   
        (7) Integrated Risk Assessment and Treatment Planning Approach to
     Multi-Factorial Diseases. While we recognize the importance of our genetic
     susceptibility tests, we also acknowledge the reality of other risk factors
     contributing to the development of disease. Thus certain diseases are often
     referred to as "multi-factorial" given that several factors contribute to
     their causation. See "Genetic Testing" at page 25. We have attempted to
     take a holistic approach toward analyzing the disease process. Therefore
     our risk assessment strategy includes not only the results of our genetic
     susceptibility tests, but also other known risk factors. By combining our
     test results together with present risk factors we are able to develop a
     more accurate risk assessment tool. We then link patient testing criteria
     to possible treatment suggestions. We package this data together with our
     genetic susceptibility tests to enhance our tests' practical utility to
     clinicians actually administering the tests.
    
 
   
        (8) Experienced in Structuring Clinical Trials to Evaluate
     Discoveries. We have extensive experience in product development, including
     designing and conducting clinical trials to evaluate genetic and drug
     discoveries. In the past, we provided clinical research services to
     pharmaceutical and medical/dental device companies. We have performed
     contract research for many of the world's leading health care and
     pharmaceutical companies. Some of our representative clients have included:
     Proctor & Gamble; Alpharma/Dumex; Implant Innovations, Inc.; W. L. Gore &
     Associates; Teledyne WaterPik; and Oral B. Commencing in 1994, our research
     team has increasingly focused on the development of our own products. Our
     research capability expedites the development process and increases our
     knowledge about target diseases. Moreover, we have already successfully
     completed our initial proof trials on all four of our genetic
     susceptibility test and confirmatory trials on three out of four of these
     tests. See "Pre-Marketing Trials/Status of Susceptibility Tests" at pages
     35 and 36.
    
 
        (9) Cost Effective Commercialization Process. Because we are focusing
     primarily on genetic susceptibility testing services and intend to develop
     at least four genetic susceptibility tests initially, with more tests in
     the future, we have designed our current product distribution and customer
     service operation in such a way that it can process, perform, track, bill
     and collect large volumes of genetic tests with appropriate quality and
     customer service support. We have carefully designed our product
     distribution and customer service operations to allow for multi-test or
     product capabilities. The design and functionality of our product
     distribution and customer service operations has been created in such a
 
                                       43
<PAGE>   48
 
     way as to enable us to easily move from a company currently selling only
     one genetic susceptibility test to a company distributing a portfolio of
     four or more such tests in multiple markets on a worldwide basis. Further,
     our operations have the capability of processing additional tests or
     products at even greater volumes with little or no modifications or
     increases in capital outlays. Moreover, as each test or product is added
     into our distribution stream, the cost per test to us decreases allowing
     for increased profitability.
 
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, 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 our business.
 
     In addition, while our main focus is on genetic susceptibility testing, we
may, in the future, endeavor to partner with pharmaceutical companies in the
area of drug development. Any drug products developed by us or our 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 us or our collaborative partners,
impose costly procedures upon us and our collaborative partners' activities,
diminish any competitive advantages that we or our collaborative partners may
attain and adversely affect our 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 September 30, 1997, we had 27 full-time employees. Most of our
employees are engaged directly in the development and commercialization of our
tests. We believe that the success of our business will depend, in part, on our
ability to attract and retain qualified personnel.
 
     Our employees are not covered by a collective bargaining agreement, and we
consider our relations with our employees to be good.
 
LEGAL PROCEEDINGS
 
     We are not a party to, nor is our property the subject of, any pending
legal proceeding.

1996 EQUITY INCENTIVE PLAN
 
     Our 1996 Equity Incentive Plan (the "Plan") was adopted by the Board of
Directors and approved by the shareholders in June 1996. A total of 750,000
shares of Common Stock were originally reserved for issuance under the Plan. The
Plan was later amended by vote of both the Board of Directors and the
shareholders in May 1997 to increase the number of shares of Common Stock
reserved for issuance under the Plan to 1,000,000. The Plan provides for grants
of incentive stock options to employees (including officers and employee
directors), nonstatutory stock options to employees (including officers and
employee directors) and consultants (including non-employee directors), stock
appreciation rights ("SARs"), stock awards and stock bonuses. The Plan allows
for administration by either the Board of Directors or a committee thereunder,
which determines optionees and the terms of options granted, including the
exercise price, number of shares subject to the option and the exercisability
thereof.
 
     The terms of options granted under the Plan generally may not exceed 10
years. The exercise price of options granted under the Plan is determined by the
Board of Directors, but, in the case of an incentive stock option, cannot be
less than 100% of the fair market value of the Common Stock on the date of
grant. The exercise price of all nonstatutory stock options must equal at least
85% of the fair market value of the Common Stock on the date of grant. The
exercise price of any stock option granted to an optionee who owns stock
possessing more than 10% of the voting power of all classes of stock of our
company must equal at least 110% of the fair market value of the Common Stock on
the date of grant. The exercise price may be paid in such consideration as
determined by the Board of Directors or a committee of the Board, including cash
and promissory notes. Options granted under the Plan to employees and
consultants have generally not been immediately exercisable and have vested over
a thirty-six (36) month period (at the rate of 16.66% of the shares subject to
the option at the end of six (6) months and 2.777% at the end of every full
month thereafter). No option may be transferred by the optionee other than by
will or the laws of descent or distribution. An optionee whose relationship with
us or any related corporation ceases for any reason (other than by death or
permanent and total disability) may exercise options in the three (3) month
period following such cessation (unless such options terminate or expire sooner
by their terms) or in such longer period determined by the Board of Directors,
provided a period of five (5) years is not exceeded.
 
     Shares subject to options granted under the Plan which have lapsed or
terminated may again be subject to options granted under the Plan. Furthermore,
the Board of Directors may offer to exchange new options for
 
                                       50
<PAGE>   55
 
existing options, with the shares subject to the existing options again becoming
available for grant under the Plan. Upon any merger or consolidation in which we
are not the surviving corporation, all outstanding options shall either be
assumed or substituted by the surviving entity. If the surviving entity
determines not to assume or substitute such options, the options terminate as of
the closing of the merger or consolidation.
 
     As of September 30, 1997, no shares of Common Stock had been issued upon
the exercise of options granted under the Plan, options to purchase 800,579
shares of Common Stock at a weighted average exercise price of $4.37 per share
were outstanding and 199,421 shares remained available for future options
grants. Prior to this offering, no SARs or restricted stock awards had been
given to our employees and consultants. The Plan will terminate in June 2006,
unless terminated sooner by the Board of Directors.
 
EMPLOYMENT AGREEMENTS
 
     In January 1996, we entered into employment contracts with all three of the
Named Executive Officers. Mr. Paul J. White, the Chief Executive Officer and
President, currently receives an annual base salary of $140,000 a year, which
will increase to $170,000 for 1998. Drs. Kenneth S. Kornman and Michael G.
Newman each currently receive an annual base salary of $135,000, which will
increase to $165,000 for 1998. Each Named Executive Officer's employment
contract has a five year term (beginning in January 1996) which is automatically
renewed for an additional twelve months unless six-months prior written notice
is given by either party. Each of the Named Executive Officers is also receiving
a $600 a month automobile allowance.
 
INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     Our company's Amended and Restated Articles of Incorporation eliminates the
liability of directors for monetary damages for an act or omission in the
director's capacity as a director, except for: (i) a breach of a director's duty
of loyalty to our company or our shareholders; (ii) an act or omission not in
good faith that constitutes a breach of duty of that director to our Company or
an act or omission that involves intentional misconduct or a knowing violation
of the law; (iii) a transaction from which a director received an improper
benefit, whether or not the benefit resulted from an action taken within the
scope of the director's office; or (iv) an act or omission for which the
liability of a director is expressly provided for by an applicable statute.
 
     If the Texas Miscellaneous Corporation Laws Act or the Texas Business
Corporation Act is amended to authorize action further eliminating or limiting
the personal liability of directors, then the liability of a director of our
company shall be eliminated or limited to the fullest extent permitted by such
statutes, as so amended. Any amendment, repeal or modification of such provision
shall be prospective only and shall not adversely affect any right or protection
of a director of our company existing at the time of such amendment, repeal or
modification.
 
     Additionally, it is the position of the Securities and Exchange Commission
that indemnification of directors and officers for liabilities arising under the
Securities Act of 1933 is against public policy and unenforceable pursuant to
Section 14 of the Securities Act of 1933.

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
 
     We believe that the transactions set forth below were made on terms no less
favorable to us than could have been obtained from unaffiliated third parties.
All future transactions, including loans, between us and our officers,
directors, principal shareholders and their affiliates will be approved by a
majority of the Board of Directors, including a majority of the independent and
disinterested outside directors, and will continue to be on terms no less
favorable to us than could be obtained from unaffiliated third parties.
 
PRIVATE PLACEMENT OF SECURITIES
 
     Between November 1996 and January 1997, we sold 189,188 shares of our
Common Stock in a private placement at a price of $3.70 per share. Between March
1997 and September 1997, we sold 293,820 shares of our Common Stock in a second
private placement transaction at a price of $5.00 per share. Except for Thomas
Moore, who subsequently became one of our directors, all investors in both such
private placements were unrelated third party investors who purchased in
arms'-length transactions.
 
DEBT/WARRANT OFFERING
 
     From August 1, 1997 through October 6, 1997, we borrowed an aggregate of
$1,780,000 from a group of lenders evidenced by promissory notes bearing
interest at 10% interest rate and due the earlier of fourteen months from the
date of the notes or the closing date of an initial public offering (the "Bridge
Loans"). As additional consideration for the Bridge Loans, we issued one warrant
for each $5.00 loaned to the Company for a total of 356,545 warrants (the
"Bridge Warrants"). Each Bridge Warrant entitles the holder to purchase one
share of Common Stock at $5.50 per share for a period of five years from the
date of issuance. The following officers and directors subscribed to the Bridge
Loans in the principal amount indicated after their names: Paul J. White
($100,000/20,000 Bridge Warrants); Kenneth S. Kornman ($100,000/20,000 Bridge
Warrants); Michael G. Newman ($100,000/20,000 Bridge Warrants); U. Spencer Allen
($50,000/10,000 Bridge Warrants); Jeanne Ambruster ($50,000/10,000 Bridge
Warrants); and Thomas A. Moore ($75,000/15,000 Bridge Warrants).
 
TRANSACTIONS WITH DIRECTORS AND EXECUTIVE OFFICERS
 
   
     Our shareholders have elected Thomas A. Moore to serve as a director. Mr.
Moore is also the CEO and President of Nelson Communications, Inc. ("NCI"). We
have recently formed a joint venture with NCI. The primary purpose of the joint
venture is to market our 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 our tests and who
subsequently send in a business reply card seeking more information. In both
aspects of the joint venture, our company will be acting as the
technology/information partner and NCI will be functioning as the marketing
partner. See "Product Development" at page 36. We believe that the terms of the
joint venture are at least as favorable to us as would be available from a
company other than NCI in an arm's-length transaction. The disinterested members
of the Board of Directors have unanimously approved the execution of this
agreement.
    
 
EMPLOYEE SALARY REDUCTION PLAN
 
     In May 1997, in order to reduce our overhead and as an additional incentive
to our employees, we instituted a voluntary salary reduction plan where our
employees could choose to receive stock options instead of salary. Employees
were offered options to purchase 600 shares of Common Stock for every $1,000
their salary was reduced. Most of our employees participated, including all of
our officers. A total of 267,079 options to purchase Common Stock at an exercise
price of $5.00 or $5.50 per share were issued to employees.

                           DESCRIPTION OF SECURITIES
 
     We are authorized to issue up to 10,000,000 shares of no par value Common
Stock and 5,000,000 shares of Preferred Stock. As of September 30, 1997, there
were outstanding 3,738,007 shares of Common Stock held of record by 72 persons.
No shares of Preferred Stock were issued or outstanding.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share on all matters
to be voted upon by the shareholders. Holders of Common Stock are entitled to
receive ratably such dividends, if any, as may be declared by the Board of
Directors out of funds legally available therefor. Upon the liquidation,
dissolution, or winding up of our company, the holders of Common Stock are
entitled to share ratably in all of our assets which are legally available for
distribution, after payment of all debts and other liabilities and the
liquidation preference of any outstanding Common Stock. Holders of Common Stock
have no preemptive, subscription, redemption or conversion rights. The
outstanding shares of Common Stock are, and the shares being sold by us in this
offering will be, when issued and delivered, validly issued, fully paid and
nonassessable.
 
   
     Based upon the number of shares outstanding as of that date, and after
giving effect to the sale of the Common Stock offered hereby, there will be
6,238,007 shares of Common Stock outstanding (assuming no exercise of
outstanding options, warrants or the Underwriters' over-allotment option).
    
 
PREFERRED STOCK
 
   
     Our company is authorized to issue up to 5,000,000 shares of Preferred
Stock. No shares of Preferred Stock are outstanding. The Board has the authority
without any further action by our shareholders to issue any or all of the
authorized shares of Preferred Stock in one or more series and to establish the
rights, preferences, privileges and restrictions thereof, including dividend
rights, conversion rights, voting rights, terms of redemption, liquidation
preferences, sinking fund terms and the number of shares constituting any series
or the designation of such series. The issuance of Preferred Stock could
adversely affect the holders of Common Stock and could have the effect of
delaying, deferring or preventing a change in our control. We have no present
plans to issue any shares of Preferred Stock. See "Effect of Preferred Stock and
Director Removal Provisions" at page 16.
    
 
OPTIONS AND WARRANTS
 
   
     Options. As of September 30, 1997, 800,579 options to purchase our Common
Stock had been issued under our 1996 Equity Incentive Plan. These options vest
over time and have a per share exercise price from $3.70 to $5.00. See "1996
Equity Incentive Plan" at page 50.
    
 
   
     Underwriters' Warrants. Upon completion of this offering, we will have
granted to the Underwriters warrants (the "Underwriters' Warrants") to purchase
250,000 shares of Common Stock. The Underwriters' Warrants are exercisable at a
price per share equal to 165% of the initial public offering price for a
four-year

period, commencing one year from the effective date of this offering. The
Underwriters' Warrants contain anti-dilution provisions providing for
adjustments of the exercise price and the number of shares underlying the
Underwriters' Warrants upon the occurrence of certain events, including any
recapitalization, reclassification, stock dividend, stock split, stock
combination or similar transaction. The Underwriters' Warrants grant to the
holders thereof certain registration rights which are described below. See
"Registration Rights" at page 55 and "Underwriting" at page 57.
    
 
   
     Bridge Warrants. From August 1, 1997 through October 6, 1997, we borrowed
an aggregate of $1,780,000 from a group of lenders evidenced by promissory notes
bearing interest at 10% interest rate and due the earlier of fourteen months
from the date of the notes or the closing date an initial public offering (the
"Bridge Loans"). The Bridge Loans are subordinate to the prior payment in full
of all of our secured obligations currently existing or those created in the
future. As additional consideration for the Bridge Loans, we issued one warrant
for each $5.00 loaned to the Company for a total of 356,545 warrants (the
"Bridge Warrants"). Each Bridge Warrant entitles the holder to purchase one
share of Common Stock at $5.50 per share for a period of five years from the
date of issuance. We can call the Bridge Warrants if the Common Stock is listed
on a national market or Nasdaq system and has had a closing price of at least
$12.00 per share for thirty (30) consecutive trading days.
    
 
REGISTRATION RIGHTS
 
     In connection with the Underwriters' Warrants, the holders of the Common
Stock issuable upon exercise of the Underwriters' Warrants have the right to
notice and inclusion in any registration statement filed by us for a period of
six (6) years commencing one year after our initial public offering closes
solely at our expense (but excluding fees and expenses of the holder's counsel
and any underwriting or selling commissions). Additionally, we agreed to allow
one demand registration for a period of four years from the effective date of
the registration statement, upon written demand of holder(s) representing a
majority of the outstanding Underwriters' Warrants, solely at our expense (but
excluding fees and expenses of the holder's counsel and any underwriting or
selling commissions). Additionally, the Bridge Warrant holders are permitted one
(1) S-3 demand registration upon request of holders of fifty percent (50%) of
the outstanding Bridge Warrants.
 
TRANSFER AGENT AND REGISTRAR
 
     U.S. Stock Transfer Corporation will act as transfer agent and registrar
for our Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this offering, we will have 6,238,007 outstanding shares
of Common Stock (assuming no exercise of outstanding options, warrants or
Underwriters' over-allotment option). Of these shares, the 2,500,000 shares sold
to the public in this offering will be freely tradeable without restrictions or
further registration under the Securities Act, except for any shares purchased
by our "affiliates" within the meaning of the Securities Act, which will be
subject to the resale limitations of Rule 144. The remaining 3,738,007 shares
held by existing shareholders were issued by us in private transactions in
reliance upon one or more exemptions under the Securities Act, are "restricted
securities" as that term is defined in Rule 144 promulgated under the Securities
Act. Such restricted securities may be sold in compliance with such Rule,
pursuant to registration under the Securities Act or pursuant to an exemption
therefrom. Generally, under Rule 144, each person holding restricted securities
for a period of one year may, every three months after such one year holding
period, sell in ordinary brokerage transactions or to market makers an amount of
shares equal to the greater of one percent of our then outstanding Common Stock
or the average weekly trading volume during the four weeks prior to the proposed
sale. In addition, sales under Rule 144 may be made only through unsolicited
"broker's transactions" or to a "market maker" and are subject to various other
conditions. The limitation on the number of shares which may be sold under Rule
144 and the "broker's transaction" requirement do not apply to restricted
securities sold for the account of a person who is not and has not been our
"affiliate" (as that term is defined in the Act) during the three months prior
to the proposed sale and who has beneficially owned the securities for at least
two years.

<PAGE>   60
 
   
     Prior to the offering, there has been no market for the Common Stock, and
no predictions can be made as to the effect, if any, that sales of shares under
Rule 144 or the availability of shares for sale will have on the market prices
prevailing from time to time. Sales of substantial amounts of Common Stock in
the public market following this offering could lower the market price of the
Common Stock. Of the 6,238,007 shares of Common Stock to be outstanding after
this offering (assuming no exercise of outstanding options, warrants or the
overallotment option), 2,500,000 shares will be freely tradeable without
restriction. Upon expiration of the lock-up agreements entered into by the
officers and directors of our company, an additional 3,258,053 shares will
become eligible for sale one year from the close of this offering, subject to
the provisions of Rule 144. Of the remaining 479,954 shares of Common Stock,
5,000 shares will be eligible for resale under Rule 144 following this offering.
The remaining 474,954 shares will have been held for less than one year and will
become eligible for sale at various dates as the one-year holding period under
Rule 144 is satisfied.
    
 
   
     In addition, we intend to file a registration statement on Form S-8 with
respect to the shares of Common Stock issuable upon exercise of options under
the 1996 Equity Incentive Plan (the "Plan"). The Plan authorizes the issuance of
options relating to up to 1,000,000 shares of Common Stock. Currently, there are
800,579 options that have been issued under the Plan which generally vest over
three years. See "1996 Equity Incentive Plan" at page 50. Upon filing of such
registration statement, the holders of such options may, subject to vesting
requirements, exercise and sell their shares immediately without restriction,
except affiliates who are subject to certain volume limitations and manner of
sale requirements of Rule 144. Holders of 356,545 warrants to purchase shares
are entitled to certain registration rights with respect to such shares. Upon
registration, such shares may be sold in the market without limitation. See
"Registration Rights" at page 55. Sales of such shares may decrease the market
price for our Common Stock. See "Underwriting" at page 57 and "Arbitrary
Offering Price of the Common Stock; Possible Volatility of Common Stock Price"
at page 16.

     The Underwriting Agreement provides that the obligations of the
Underwriters thereunder are subject to approval of certain legal matters by
counsel and to various other conditions. The nature of the Underwriters'
obligations is such that they are committed to purchase and pay for all of the
above shares of Common Stock if any are purchased. The Underwriters propose to
offer the shares of Common Stock directly to the public at the public offering
price set forth on the cover page of this Prospectus.
 
   
     We have granted to the Underwriters a 30-day over-allotment option to
purchase up to 375,000 additional shares of Common Stock at the public offering
price less the underwriting discount. The Underwriters may exercise such option
only to cover over-allotments made in connection with the sale of the shares of
Common Stock offered hereby.
    
 
   
     We have also agreed to sell to the Underwriters, for nominal consideration,
warrants (the "Underwriters' Warrants") to purchase the number of shares of our
Common Stock equal to 10% of the total number of shares of Common Stock sold in
this offering at a price per share equal to 165% of the initial public offering
price of the Common Stock. The Underwriters' Warrants will be exercisable for a
period of four years commencing one year from the effective date of this
offering and will contain certain demand and "piggyback" registration rights
with respect to the Common Stock issuable upon the exercise of the Underwriters'
Warrants. The Underwriters' Warrants are not transferable (except to members of
the syndicate and their affiliates). The exercise price and the number of shares
issuable upon exercise may, under certain circumstances, be subject to
adjustment pursuant to antidilution provisions.
    
 
     We have agreed to allow the Underwriters a commission of eight percent (8%)
of the public offering price of the shares of Common Stock. Additionally, we
will be paying the Underwriters, following the closing of this offering, a
nonaccountable expense allowance equal to three percent (3%) of the aggregate
public offering price of the shares of Common Stock, less any applicable
deposits.
 
     We have further agreed to indemnify the Underwriters against certain
liabilities, losses and expenses, including liabilities under the Securities
Act, or to contribute to payments that the Underwriters may be
 
                                       57
<PAGE>   62
 
required to make in respect thereof. We also have agreed to reimburse the
Underwriters for certain out-of-pocket expenses incurred in connection with the
offering.
 
     The Underwriters have advised us that they do not intend to make sales to
discretionary accounts.
 
     Our officers and directors who in the aggregate beneficially own 3,258,053
shares of Common Stock have agreed not to, directly or indirectly, sell, offer,
contract to sell, make any short sale, pledge or otherwise dispose of such
shares for a period of 12 months after the date of the closing of this offering.
 
   
     In connection with this offering certain underwriters may engage in passive
market making transactions in the shares in accordance with Rule 103 of
Regulation M. Further, the Underwriters' selling group members and their
respective affiliates may engage in transactions that stabilize, maintain or
otherwise affect the market price of our shares. These transactions may include
stabilization transactions permitted by Rule 104 of Regulation M, under which
persons may bid for or purchase shares to stabilize the market price. The
Underwriters may also create a "short position" for their own account by selling
more shares in the offering than they are committed to purchase, and in that
case they may purchase shares in the open market after this offering is
completed to cover all or a part of their short position. The Representative may
also cover all or a portion of their short position, up to 375,000 shares, by
exercising their over-allotment option described above and on the cover of this
prospectus.
    
 
                                 LEGAL MATTERS
 
     Certain legal matters with respect to the legality of the issuance of the
Common Stock offered hereby will be passed upon for us by Jeffers, Wilson, Shaff
& Falk, LLP, Irvine, California. Certain legal matters in connection with the
offering will be passed upon for the Underwriters by William M. Prifti, Esq.,
Lynnfield, Massachusetts.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders
Medical Science Systems, Inc.
 
     We have audited the accompanying balance sheet of Medical Science Systems,
Inc. as of December 31, 1996 and the related statements of operations,
shareholders' deficit, and cash flows for each of the two years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Medical Science Systems,
Inc. as of December 31, 1996, and the results of its operations and its cash
flows, for each of the two years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Line of Business
 
     Medical Science Systems, Inc., a Texas corporation, (the "Company")
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, accordingly, the results of operations for the year ended
December 31, 1995 include Oral Science Systems from January 1, 1995 to the date
of the merger.
 
     The Company is currently developing a line of genetic susceptibility tests
and therapeutic targets for common diseases. As of December 31, 1996, the
Company has commercially introduced one such product and is in various stages of
development for several others. The Company also provides clinical trials and
research services under contract to pharmaceutical companies, and such services
generated substantially all of the Company's revenues for the years ended
December 31, 1996 and 1995.
 
  Interim Financial Information
 
     The unaudited financial information furnished herein reflects all
adjustments, consisting only of normal recurring adjustments, which in the
opinion of management, are necessary to fairly state the Company's financial
position, the results of its operations, and cash flows for the periods present.
The results of operations for the nine months ended September 30, 1997 are not
necessarily indicative of results for the entire fiscal year ending December 31,
1997.
 
  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, accounts receivable, accounts payable,
accrued expenses, and accrued officer compensation, the carrying amounts
approximate fair value due to their short maturities. The amounts shown for line
of credit, 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.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

  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:
 
<TABLE>
                <S>                                                   <C>
                Computer equipment..................................  3 years
                Furniture and fixtures..............................  5 years
                Computer software...................................  3 years
                Equipment under capital leases......................  3 years
</TABLE>
 
     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 of their useful lives of ten
years beginning from the time the patents are awarded. The Company was issued a
patent in August 1997 and currently has ten patents pending; accordingly, the
Company had not recognized any amortization related to the ten pending patents
as of September 30, 1997. The Company recognized $321 (unaudited) in
amortization expense for the nine months ended September 30, 1997 related to the
patent issued in August 1997.
 
  Deferred Offering Costs
 
     Amounts paid for costs associated with an anticipated initial public
offering ("IPO") are capitalized and will be recorded as a reduction to common
stock upon the completion of the IPO. In the event that the IPO is not
successful, the deferred offering costs will be charged to expense.
 
  Revenue Recognition
 
     Contract revenues are recognized ratably as services are provided based on
a fixed contract price or on negotiated hourly rates. The Company has no
unbilled accounts receivable under any contracts at December 31, 1996 and
September 30, 1997 (unaudited). Provision for anticipated losses on fixed-price
contracts is made in the period such losses are identified. Revenue from genetic
susceptibility tests is recognized when the tests have been completed and the
results reported to the doctors.
 
  Concentrations of Credit 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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
               FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995 AND
       FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996 (UNAUDITED)
             (THE INFORMATION WITH RESPECT TO THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1997 AND 1996 IS UNAUDITED.)
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     During the year ended December 31, 1996, the Company did business with
three customers whose sales comprised approximately 99% of revenues. Amounts due
from these customers represented 100% of accounts receivable at December 31,
1996.
 
     During the year ended December 31, 1995, the Company did business with two
customers whose sales comprised approximately 85% of revenues.
 
     During the nine months ended September 30, 1996, the Company did business
with three customers whose sales comprised approximately 100% 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." Deferred tax assets and liabilities reflect the expected future
tax consequences of events that have been included in the financial statements
and tax returns. Deferred tax assets and liabilities are determined based upon
the difference between the financial statement and tax bases of assets and
liabilities, using the enacted tax rates in effect for the year in which the
differences are expected to reverse. The Company has not recorded any deferred
tax assets related to operating loss carryforwards generated subsequent to
September 30, 1996 due to the uncertainty of the Company's ability to ultimately
recognize the benefits of such carryforwards.
 
  Net Income (Loss) Per Share
 
     Net income (loss) per share is based on the weighted average number of
common and common equivalent shares outstanding during the period. In connection
with the Company's IPO, common stock issued for consideration below the IPO per
share price (assuming an IPO price of $9.00) during the twelve months before the
filing of the registration statement, plus options and warrants to purchase the
Company's 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 shares outstanding as if they had been outstanding for
all periods presented.
 
  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.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

  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 will be reduced or eliminated.
 
     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 payors.
If both third-party payors 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 any
discoveries resulting from Sheffield University's research. The agreement may be
terminated with or without cause by either party upon six-months notice. 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
 
     The Financial Accounting Standards Board ("FASB") issued SFAS No. 128,
"Earnings Per Share," which is effective for financial statements issued for
periods ending after December 15, 1997, including interim periods. SFAS No. 128
requires public companies to present basic earnings per share and, if
applicable, diluted earnings per share instead of primary and fully-diluted
earnings per share. The Company does not believe that diluted earnings per share
in accordance with SFAS No. 128 will be materially different from the earnings
per share previously reported.
 
     SFAS No. 129, "Disclosure of Information about Capital Structures," issued
by FASB is effective for financial statements ending after December 15, 1997.
The new standard reinstates various securities disclosure requirements
previously in effect under Accounting Principles Board ("APB") Opinion No. 15,
"Computing Earnings per Share," which has been superseded by SFAS No. 128. The
Company does not expect adoption of SFAS No. 129 to have a material effect, if
any, on its financial position or results of operations.
 
     SFAS No. 130, "Reporting Comprehensive Income," issued by FASB 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 4 -- 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 (unaudited) plus interest. The line of
credit bore interest at the bank's prime rate plus 1.75% (effectively 10% at
December 31, 1996) which was payable monthly in arrears. At December 31, 1996,
the Company had outstanding borrowings of $353,723 under the revolving line of
credit and at September 30, 1997 had outstanding borrowings of $671,824
(unaudited) under the notes payable.
 
   
     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.
    
 
   
     Required principal payments under the notes payable are as follows:

NOTE 4 -- TERM LOAN AND REVOLVING LINE OF CREDIT WITH BANK (CONTINUED)

     Both the notes payable and the revolving line of credit are secured 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 and the revolving line of credit. The
agreements also include certain covenants which restrict, among other things,
the occurrence of new indebtedness.
 
NOTE 5 -- 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
$1,550,000 and issued 310,545 warrants to purchase the Company's common stock.
The Notes accrue interest at 10% per annum, and all unpaid principal and
interest are 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 the earlier of five years from the date of issuance or 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 will recognize additional interest
expense of $310,545 over the 14-month term of the Notes with the unamortized
portion at the closing of the Company's IPO being charged to interest expense
immediately.
    
 
NOTE 6 -- 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, 1996 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, 1996,
the Company had net operating loss carryforwards of approximately $590,000 and
$295,000 for federal and state income tax purposes, respectively, expiring in
varying amounts through the year 2012, which are available to offset future
federal and state taxable income. The Company also had a research tax credit of
$14,400 at December 31, 1996 that expires in 2012. 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 as a
result of the private placements of common stock and issuance of stock options.

NOTE 7 -- CAPITAL STOCK
 
  Stock Split
 
     In June 1996, the Company's shareholders approved a 1,083.333 for 1 stock
split which was completed in July 1996. All references in the financial
statements to numbers of common shares and per common share amounts have been
restated to reflect the stock split. All disclosures related to sales of common
stock, warrants, employee stock plans, and other common stock transactions for
all periods presented have also been restated to reflect the stock split.
 
  Private Placements of Common Stock
 
     In September 1996, the Company's Board of Directors authorized the private
offering of shares of the Company's common stock at $3.70 per share up to an
aggregate of $5,250,000. For the year ended December 31, 1996 and the nine
months ended September 30, 1997, the Company sold 40,540 and 148,648 (unaudited)
shares, respectively, of its common stock in private placement transactions at a
price of $3.70 per share. The gross proceeds of the sale were approximately
$150,000 and $550,000 (unaudited), respectively.
 
     During the nine months ended September 30, 1997, the Company sold 293,820

NOTE 8 -- EMPLOYEE BENEFIT PLAN
 
     In 1988, the Company adopted a profit sharing plan covering substantially
all of its employees. Under the profit sharing plan, the Company may, at the
discretion of the Board of Directors, contribute a portion of the Company's
current or accumulated earnings. Company contributions, if any, are credited to
participant accounts and are immediately vested. During the years ended December

NOTE 9 -- STOCK OPTION PLAN
 
     In June 1996, the Company's shareholders approved the adoption of the
Medical Science Systems, Inc. 1996 Equity Incentive Plan (the "Plan"). The Plan
provides for the award of nonqualified and incentive stock options, restricted
stock, and stock bonuses to employees, directors, officers, and consultants of
the Company. The Plan provides for the grant of nonqualified and incentive stock
options to all directors, officers, and employees of the Company. A total of
1,000,000 shares of the Company's common stock have been reserved for award
under the amended Plan.
 
     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 which 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 awardshare appreciation rights ("SARs") either in tandem with
stock options or independently. At December 31, 1996 and September 30, 1997
(unaudited), 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:

     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, 1996: dividend yields of 0%;
expected volatility of 70%; risk-free interest rates of 6.0%; and expected life
of 3 years. The weighted average fair value of options granted during the year
ended December 31, 1996 was $1.87, and the weighted average exercise price was
$3.70.
 
     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

NOTE 9 -- STOCK OPTION PLAN (CONTINUED)

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.

     The weighted average remaining contractual life of options outstanding
issued under the Plan is ten years at December 31, 1996.
 
     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 September 30, 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 of salary. Employees elected
to reduce their salaries up to 50% 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 will record an expense relating to the
issuance of these stock option in the amount of $74,189 per month for each of
the six months from May 1997 to October 1997.

     From October 1, 1997 through October 6, 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 $230,000 and issued 46,000 warrants to purchase the
Company's common stock. The Notes accrue interest at 10% per annum, and all
unpaid principal and interest are due the earlier of fourteen 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 the earlier of five years
from the date of issuance or 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 30 consecutive trading days.
In connection with the issuance of such warrants, the Company will recognize
additional interest expense of $46,000 over the fourteen month term of the Notes
with the unamortized portion at the closing of the Company's IPO being charged
to interest expense immediately.

               PART II -- INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Our company's Amended and Restated Articles of Incorporation eliminates the
liability of directors for monetary damages for an act or omission in the
director's capacity as a director, except for: (1) a breach of a director's duty
of loyalty to our company or our shareholders; (2) an act or omission not in
good faith that constitutes a breach of duty of that director to our company or
an act or omission that involves intentional misconduct or a knowing violation
of the law; (3) a transaction from which a director received an improper
benefit, whether or not the benefit resulted from an action taken within the
scope of the director's office; or (4) an act or omission for which the
liability of a director is expressly provided for by an applicable statute.
 
     If the Texas Miscellaneous Corporation Laws Act or the Texas Business
Corporation Act is amended to authorize action further eliminating or limiting
the personal liability of directors, then the liability of a director of our
company shall be eliminated or limited to the fullest extent permitted by such
statutes, as so amended. Any amendment, repeal or modification of such provision
shall be prospective only and shall not adversely affect any right or protection
of a director of our company existing at the time of such amendment, repeal or
modification.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES
 
     1. Between November 1996 and January 1997, we sold 189,188 shares of our
Common Stock to seven (7) investors in a private placement at a price of $3.70
per share. No commissions or finder's fees were paid.
 
     Within the 12 month period preceding such private placement, the Company
did not make any offer or sales of securities. These securities were issued in
reliance upon the exemption set forth in Rule 504 of Regulation D of the
Securities Act.
 
     2. Between March 1997 and September 1997, we sold 292,060 shares of our
Common Stock to forty-six (46) investors in a second private placement
transaction at a price of $5.00 per share. We issued 1,760 shares of our Common
Stock as a finder's fee with respect to such private placement.
 
     Fewer than 35 purchasers in such offering were unaccredited. Each purchaser
executed subscription agreements representing that such purchaser either alone
or with his representatives had knowledge and experience sufficient to evaluate
the merits and risks of the investment. These securities were issued in reliance
upon the exemption set forth in Rule 506 of Regulation D of the Securities Act.
 
     3. From December 1996 through May 1997, our company has issued a total of
800,579 incentive and non-qualifying stock options to thirty-seven (37)
employees and consultants under our 1996 Equity Incentive Plan. Of the total
issued, 533,500 were issued in exchange for services rendered to our company.
These options generally vest over 36 months and have a per share exercise price
from $3.70 to $5.00. The balance of
 
                                      II-1
<PAGE>   82
 
the options (267,079) were issued in May 1997. In order to reduce our overhead
and as an additional incentive to our employees, we instituted a voluntary
salary reduction plan where our employees could choose to receive stock options
instead of salary. Employees were offered options to purchase 600 shares of
Common Stock for every $1,000 their salary was reduced. Most of our employees
participated, including all of our officers. A total of 267,079 options to
purchase Common Stock at an exercise price of $5.00 or $5.50 per share were
issued. These options vested immediately.
 
     The offer of these securities was made solely to directors and employees of
the Company. The offering was made without any public advertisement. These
securities were issued in reliance upon the exemptions set forth in Section 4(2)
of the Securities Act on the basis that they were issued under circumstances not
involving a public offering. It should also be noted that in December 1996, a
permit was issued by the California Department of Corporations qualifying grants
of options or common stock under the company's 1996 Equity Incentive Plan.
 
     4. From August 1, 1997 through October 6, 1997, we borrowed an aggregate of
$1,780,000 from twenty-eight (28) lenders evidenced by promissory notes bearing
interest at 10% interest rate and due the earlier of fourteen months from the
date of the notes or the closing date of an initial public offering (the "Bridge
Loans"). As additional consideration for the Bridge Loans, we issued one warrant
for each $5.00 loaned to the Company for a total of 356,000 warrants (the
"Bridge Warrants"). Each Bridge Warrant entitles the holder to purchase one
share of Common Stock at $5.50 per share for a period of five years from the
date of issuance. An additional 545 Bridge Warrants were issued as a finder's
fee. The following officers and directors subscribed to the Bridge Loans in the
principal amount indicated after their names: Paul J. White ($100,000/20,000
Bridge Warrants); Kenneth S. Kornman ($100,000/20,000 Bridge Warrants); Michael
G. Newman ($100,000/20,000 Bridge Warrants); U. Spencer Allen ($50,000/10,000
Bridge Warrants); Jeanne Ambruster ($50,000/10,000 Bridge Warrants); and Thomas
A. Moore ($75,000/15,000 Bridge Warrants). The other twenty-one investors were
outside private parties. Other than the 545 Bridge Warrants referenced above, no
commissions or finder's fees were paid by the Company.
 
     Fewer than 35 purchasers in such offering were unaccredited. Each purchaser
executed subscription agreements representing that such purchaser either alone
or with his representatives had knowledge and experience sufficient to evaluate
the merits and risks of the investment. These securities were issued in reliance
upon the exemption set forth in Rule 506 of Regulation D of the Securities Act.

ITEM 28. UNDERTAKINGS.
 
     The undersigned small business issuer hereby undertakes:
 
        (1) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 (the "Act") may be permitted to directors, officers
     and controlling persons of the registrant pursuant to the foregoing
     provisions, or otherwise, the registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the registrant of expenses incurred
     or paid by a director, officer or controlling person of the registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, we will, unless in the opinion of our counsel
     the matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Act and will be governed by the
     final adjudication of such issue.
 
        (2) The undersigned registrant hereby undertakes that:
 
           (i) For purposes of determining any liability under the Securities
        Act of 1933, the information omitted from the form of prospectus filed
        as part of this registration statement in reliance upon Rule 430A and
        contained in a form of prospectus filed by the registrant pursuant to
        Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed
        to be part of this registration statement as of the time it was declared
        effective.
 
           (ii) For the purpose of determining any liability under the
        Securities Act of 1933, each post-effective amendment that contains a
        form of prospectus shall be deemed to be a new registration statement
        relating to the securities offered therein, and the offering of such
        securities at that time shall be deemed to be the initial bona fide
        offering thereof.

registrant certifies that is has reasonable grounds to believe that it meets all

Nutmeg Securities ,Ltd.
495 Post Road East
Westport, CT 06880

   
Dear Sirs:
    

   
     Medical Science Systems, Inc., a Texas corporation (the "Company"),
proposes to issue and sell to the several Underwriters named in Schedule I
hereto (the "Underwriters"), two million five hundred thousand shares of common
stock of the Company (the "Securities"). The Company hereby confirms the
agreement made by it with respect to the purchase of the Securities by the
Underwriter, which Securities are more fully described in the Registration
Statement referred to below. Nutmeg Securities, Ltd. is referred to herein as
the "Underwriter" or the "Representative."
    

     You have advised the Company that the Underwriters desire to act on a firm
commitment basis to publicly offer and sell the Securities for the Company and
that you are authorized to execute this Agreement. The Company confirms the
agreement made by it with respect to the relationship with the Underwriters as
follows:

   
1.   Filing of Registration Statement with S.E.C. and Definitions. A
Registration Statement and Prospectus on Form SB-2 (File No. 333-37441) with
respect to the Securities has been carefully and accurately prepared by the
Company in conformity with the requirements of the Securities Act of 1933, as
amended (the "Act"), and the published rules and regulations (the "Rules and
Regulations") thereunder or under the Securities Exchange Act of 1934, as
amended (the "Exchange Act") and has been filed with the Securities and Exchange
Commission (the "Commission") and such other states that the Underwriter deems
necessary in its discretion to so file to permit a public offering and trading
thereunder. Such registration statement, including the prospectus, Part II, and
all financial schedules and exhibits thereto, as amended at the time when it
shall become effective, is herein referred to as the "Registration Statement,"
and the prospectus included as part of the Registration Statement on file with
the Commission that discloses all the information that was omitted from the
prospectus on the effective date pursuant to Rule 430A of the Rules and
Regulations with any changes contained in any prospectus filed with the
Commission by the Company with the Underwriters consent after the effective date
of the Registration Statement, is herein referred to as the "Final Prospectus."
The prospectus included as part of the Registration Statement of the Company and
in any amendments thereto prior to the effective date of the Registration
Statement is referred to herein as a "Preliminary Prospectus."
    

   
2.   Discount, Delivery, and Sale of the Securities.
    

   
     (a) Subject to the terms and conditions of this Agreement, and on the basis
of the representations, warranties, and agreements herein contained, the Company
agrees to sell to, and the Underwriters agree to buy from the Company at a
purchase price of $      per share before any underwriter expense allowances, an
aggregate of 2,500,000 shares of Common Stock, on a firm commitment basis (the
"Initial Securities").
    

     It is understood that the Underwriters propose to offer the Securities to
be purchased hereunder to the public upon the terms and conditions set forth in
the Registration Statement, after the Registration Statement becomes effective.


                                                                               1

<PAGE>   2

   
     (b) Delivery of the Securities against payment of the purchase price
therefor by certified or official bank check or checks or wire transfer in
next-day funds, payable to the order of the Company shall take place at the
offices of the clearing broker for the Underwriter at New York City, within
three (3) business days after the Securities are first traded (or such other
place as may be designated by agreement between you and the Company) at 11:00
A.M., New York time or such time and date as you and the Company may agree upon
in writing, such time and date of payment and delivery for the Securities being
herein called (the "Initial Closing Date").
    

   
     The Company will make the certificates for the shares of Common Stock and
Underwriters' Warrants (as defined herein) to be purchased by the Underwriters
hereunder available to the Underwriter for inspection and packaging at least one
(1) full business day prior to the Initial Closing Date. The certificates shall
be in such names and denominations as the Underwriter may request to the Company
in writing at least two (2) full business days prior to any closing date.
    

   
     (c) In addition, subject to the terms and conditions of this Agreement and
on the basis of the representations, warranties and agreements herein contained,
the Company grants an option to the Underwriters to purchase up to an additional
375,000 shares of Common Stock ("Option Securities") at the same terms as the
Underwriters shall pay for the Initial Securities being sold by the Company
pursuant to the provisions of Section 2(a) hereof. This option may be exercised
from time to time, for the purpose of covering overallotments, within thirty
(30) days after (i) the effective date of the Registration Statement if the
Company has elected not to rely on Rule 430A under the Rules and Regulations or
(ii) the date of this Agreement if the Company has elected to rely upon Rule
430A under the Rules and Regulations, upon written notice by the Underwriter
setting forth the number of Option Securities as to which the Underwriter is
exercising the option and the time and date at which such certificates are to be
delivered. Such time and date shall be determined by the Underwriter but shall
not be earlier than four (4) nor later than ten (10) full business days after
the date of the exercise of said option. Nothing herein shall obligate the
Underwriter to make any overallotment.
    

     (d) Definitive certificates in negotiable form for the Securities to be
purchased by the Underwriter hereunder will be delivered at the closing by the
Company to the Underwriters against payment of the purchase price by the
Underwriters by certified or bank cashier's checks or wire transfer in next day
funds payable to the order of the Company.

     (e) The information set forth under "Underwriting" in any preliminary
prospectus and Prospectus relating to the Securities and the information set
forth in the last paragraph on the front cover page, under the last paragraph on
page 2 concerning stabilization and over-allotment by the Underwriters, and
(insofar as such information relates to the Underwriters) constitutes the only
information furnished by the Underwriter to the Company for inclusion therein,
and you represent and warrant to the Company that the statements made therein
are correct.

   
     (f) On the Initial Closing Date, the Company shall issue and sell to the
Underwriters, warrants (the "Underwriters' Warrants") at a purchase price of
$.001 per Underwriters' Warrant, which shall entitle the holders thereof to
purchase an aggregate of 250,000 shares of Common Stock. The shares of common
stock issuable upon the exercise of the Underwriters' Warrants are hereinafter
referred to as the "Warrant Shares" (collectively with the Underwriters'
Warrants, the "Underwriters' Securities"). The Underwriters' Warrants shall be
exercisable for a period of four (4) years commencing one (1) year from the
effective date of the Registration Statement at a price equaling one hundred
sixty five percent (165%) of the initial public offering price of the 
Securities. The form of Underwriters' Warrant shall be substantially in the 
form filed as an Exhibit to the Registration Statement. Payment for the 
Underwriters' Warrants shall be made on the Initial Closing Date.
    

                                                                               2

3.   Representations and Warranties of the Company.

     (a) The Company represents and warrants to you as follows:

   
        (i) The Company has prepared and filed with the Commission a
registration statement, and an amendment or amendments thereto, on Form SB-2
(No. 333-37441), including any related preliminary prospectus ("Preliminary
Prospectus"), for the registration of the Securities, the Underwriters' Warrant
and the Warrant Shares (sometimes referred to herein collectively as the
"Registered Securities"), under the Act, which registration statement and
amendment or amendments have been prepared by the Company in conformity with the
requirements of the Act, and the Rules and Regulations. The Company will
promptly file a further amendment to said registration statement in the form
heretofore delivered to the Underwriter and will not file any other amendment
thereto to which the Underwriter shall have objected verbally or in writing
after having been furnished with a copy thereof. Except as the context may
otherwise require, such registration statement, as amended, on file with the
Commission at the time the registration statement becomes effective (including
the prospectus, financial statements, any schedules, exhibits and all other
documents filed as a part thereof or that may be incorporated therein
(including, but not limited to those documents or information incorporated by
reference therein) and all information deemed to be a part thereof as of such
time pursuant to paragraph (b) of Rule 430(A) of the Rules and Regulations), is
hereinafter called the "Registration Statement," and the form of prospectus in
the form first filed with the Commission pursuant to Rule 424(b) of the Rules
and Regulations, is hereinafter called the "Prospectus."
    

         (ii) Neither the Commission nor any state regulatory authority has
issued any order preventing or suspending the use of any Prospectus or the
Registration Statement and no proceeding for an order suspending the
effectiveness of the Registration Statement or any of the Company's securities
has been instituted or is pending or threatened. Each such Prospectus and/or any
supplement thereto has conformed in all material respects with the requirements
of the Act and the Rules and Regulations and on its date did not include any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein not misleading, in light of the circumstances
under which they were made and (i) the Prospectus and/or any supplement thereto
will contain all statements which are required to be stated therein by the Act
and Rules and Regulations, and (ii) the Prospectus and/or any supplement thereto
will not include any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, in light of the circumstances under which they were
made; provided, however, that no representations, warranties or agreements are
made hereunder as to information contained in or omitted from the Prospectus in
reliance upon, and in conformity with, the written information furnished to the
Company by you as set forth in Section 2(e) above.

         (iii) The Company has been duly incorporated and is validly existing as
a corporation in good standing under the laws of the state of its incorporation,
with full power and authority (corporate and other) to own its properties and
conduct its businesses as described in the Prospectus and is duly qualified to
do business as a foreign corporation in good standing in all other jurisdictions
in which the nature of its business or the character or location of its
properties requires such qualification, except where the failure to so qualify
would not have a material adverse effect on the business, properties or
operations of the Company and the subsidiaries as a whole.

   
         (iv) The Company has full legal right, power and authority to
authorize, issue, deliver and sell the Securities, the Option Securities and the
Underwriters' Securities and to enter into both this Agreement and the
Underwriters' Warrant, and to consummate the transactions provided for in such
agreements, and each of such agreements has been duly and properly authorized,
and on the Initial Closing Date will be duly and properly executed and delivered
by the Company. This Agreement constitutes, and on the Initial Closing Date the
Underwriters' Warrant will then constitute, valid and binding agreements,
enforceable in accordance with their respective terms (except as the
enforceability thereof may be limited by bankruptcy or other similar laws
affecting the rights of creditors generally or by general equitable principles
and except as the enforcement of indemnification provisions may be limited by
federal or state securities laws).
    

         (v) Except as disclosed in the Prospectus, the Company is not in
violation of its respective certificate or articles of incorporation or bylaws
or in default in the performance or observance of any material obligation,

     (xx) Except as may be set forth in the Registration Statement, the Company

"multiemployer plan" as such terms are defined in Sections 3(2), 3(l) and 3(37),
respectively, of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") ("ERISA Plans"). The Company does not maintain or contribute, now or
at any time previously, to a defined benefit plan, as defined in Section 3(35)
of ERISA. No ERISA Plan (or any trust created thereunder) has engaged in a
"prohibited transaction" within the meaning of Section 406 of ERISA or Section
4975 of the Internal Revenue Code (the "Code"), which could subject the Company
to any tax penalty on prohibited transactions and which has not adequately been
corrected. Each ERISA Plan is in compliance with all material reporting,
disclosure and other requirements of the Code and ERISA as they relate to any
such ERISA Plan. Determination letters have been received from the Internal
Revenue Service with respect to each ERISA Plan which is intended to comply with
Code Section 401 (a), stating that such ERISA Plan and the attendant trust are
qualified thereunder. The Company has never completely or partially withdrawn
from a "multiemployer plan."

                                                                             6

<PAGE>   7

   
     (xxi) None of the Company, or any of its employees, directors,
stockholders, or affiliates (within the meaning of the Rules and Regulations)
has taken or will take, directly or indirectly, any action designed to or which
has constituted or which might be expected to cause or result in, under the
Exchange Act, or otherwise, stabilization or manipulation of the price of any
security of the Company to facilitate the sale or resale of the Securities,
Option Securities, Underwriters' Securities or otherwise.
    

   
     (xxii) None of the patents, patent applications, trademarks, service marks,
trade names, copyrights, and licenses and rights to the foregoing presently
owned or held by the Company, are in dispute or, to the best knowledge of the
Company's management are in any conflict with the right of any other person or
entity. The Company (i) except as disclosed in the Prospectus owns or has the
right to use, all patents, trademarks, service marks, trade names and
copyrights, technology and licenses and rights with respect to the foregoing,
used in the conduct of its business as now conducted or proposed to be conducted
without infringing upon or otherwise acting adversely to the right or claimed
right of any person, corporation or other entity under or with respect to any of
the foregoing, and except as set forth in the Prospectus or otherwise disclosed
to the Underwriters in writing, to the best knowledge of the Company's
management is not obligated or under any liability whatsoever to make any
material payments by way of royalties, fees or otherwise to any owner or
licensee of, or other claimant to, any patent, trademark, service mark, trade
name, copyright, know-how, technology or other intangible asset, with respect to
the use thereof or in connection with the conduct of its business or otherwise.
    

     (xxiii) Except as disclosed in the Prospectus the Company owns and has
adequate right to use to the best knowledge of the Company's management all
trade secrets, know-how (including all other unpatented and/or unpatentable
proprietary or confidential information, systems or procedures), inventions,
designs, processes, works of authorship, computer programs and technical data
and information (collectively herein "intellectual property") required for or
incident to the development, manufacture, operation and sale of all products and
services sold or proposed to be sold by the Company. The Company is not aware of
any such development of similar or identical trade secrets or technical
information by others. The Company has valid and binding confidentiality
agreements with all of its officers, covering its intellectual property (subject
to the equitable powers of any court), which agreements have remaining terms of
at least two years from the effective date of the Registration Statement except
where the failure to have such agreements would not materially and adversely
effect the Company's business taken as a whole. The Company has good and
marketable title to, or valid and enforceable leasehold estates in, all items of
real and personal property stated in the Prospectus, to be owned or leased by it
free and clear of all liens, charges, claims, encumbrances, pledges, security
interests, defects, or other restrictions or equities of any kind whatsoever,
other than those referred to in the Prospectus and liens for taxes not yet due
and payable.

exchangeable for or evidencing any right to purchase or subscribe for any shares
of Common Stock (either pursuant to Rule 144 of the Rules and Regulations or
otherwise) for a period of not less than twelve (12) months following such
effective date without the prior written consent of the Underwriter. The Company
will cause the Transfer Agent, as defined below, to mark an appropriate legend
on the face of stock certificates representing all of such securities and to
place "stop transfer" orders on the Company's stock ledgers.
    

     (xxvi) The Registered Securities have been approved for listing on NASDAQ
or an Exchange.

                                                                              7

foregoing persons or entities.
    

   
     (xxviii) Any certificate signed by any officer of the Company, and
delivered to the Underwriters or to the Underwriters' counsel (as defined

4. Covenants of the Company. The Company covenants and agrees with you that:

     (a) It will cooperate in all respects in making the Prospectus effective
and will not at any time, whether before or after the effective date, file any
amendment to or supplement to the Prospectus of which you shall not previously
have been advised and furnished with a copy or to which you or your counsel
shall have reasonably objected or which is not in material compliance with the
Act and the Rules and Regulations or applicable state law.

   
     As soon as the Company is advised thereof, the Company will advise you, and
confirm the advice in writing, of the receipt of any comments of the Commission
or any state securities department, when the Registration Statement becomes
effective if the provisions of Rule 430A promulgated under the Act will be
relied upon, when the Prospectus has been filed in accordance with said Rule
430A, of the effectiveness of any post-effective amendment to the Registration
Statement or Prospectus, or the filing of any supplement to the Prospectus or
any amended Prospectus, of any request made by the Commission or any state
securities department for amendment of the Prospectus or for supplementing of
the Prospectus or for additional information with respect thereto, of the
issuance of any stop order suspending the effectiveness of the Prospectus or any
order preventing or suspending the use of any Prospectus or any order suspending
trading in the Common Stock of the Company, or of the suspension of the
qualification of the Securities, the Option Securities or the Underwriters'
Securities for offering in any jurisdiction, or of the institution of any
proceedings for any such purposes, and will use its best efforts to prevent the
issuance of any such order and, if issued, to obtain as soon as possible the
lifting or dismissal thereof.
    

   
     The Company has caused to be delivered to you copies of such Prospectus,
and the Company has consented and hereby consents to the use of such copies for
the purposes permitted by law. The Company authorizes you and the dealers to use
the Prospectus and such copies of the Prospectus in connection with the sale of
the Securities, the Option Securities and the Underwriters' Securities for such
period as in the opinion of your counsel and our counsel the use thereof is
required to comply with the applicable provisions of the Act and the Rules and
Regulations. The Company will prepare and file with the states, promptly upon
your request, any such amendments or supplements to the Prospectus, and take any
other action, as, in the opinion of your counsel, may be necessary or advisable
in connection with the initial sale of the Securities, the Option Securities and
the Underwriters' Securities and will use its best efforts to cause the same to
become effective as promptly as possible.
    

     The Company shall file the Prospectus (in form and substance satisfactory
to the Underwriter) or transmit the Prospectus by a means reasonably calculated
to result in filing with the Commission pursuant to rule 424(b)(1) or pursuant
to Rule 424(b)(3) not later than the Commission's close of business on the
earlier of (i) the second business day following the execution and delivery of
this Agreement, and (ii) the fifth business day after the effective date of the
Registration Statement.

   
     In case of the happening, at any time within such period as a Prospectus is
required under the Act to be delivered in connection with the initial sale of
the Securities, the Option Securities and the Underwriters' Securities, of any
event of which the Company has knowledge and which materially affects the
Company, or the securities thereof, and which should be set forth in an
amendment of or a supplement to the Prospectus in order to make the statements
therein not then misleading, in light of the circumstances existing at the time
the Prospectus is required under the Act to be delivered, or in case it shall be
necessary to amend or supplement the Prospectus to comply with the Act, the
Rules and Regulations or any other law, the Company will forthwith prepare and
furnish to you copies of such 
    

                                                                              9

amended Prospectus or of such supplement to be attached to the Prospectus, in
such quantities as you may reasonably request, in order that the Prospectus, as
so amended or supplemented, will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances under which they are made. The preparation and furnishing of any
such amendment or supplement to the Prospectus or supplement to be attached to
the Prospectus shall be without expense to you.

   
     The Company will to the best of its ability comply with the Act, the
Exchange Act and applicable state securities laws so as to permit the initial

Securities under the Act, the Rules and Regulations, and applicable state
securities laws.
    

   
     (b) It will cooperate to qualify the Securities and the Option Securities
and the Underwriters' Securities for initial sale under the securities laws
of such jurisdictions as you may designate and will make such applications and
furnish such information as may be required for that purpose, provided the
Company shall not be required to qualify as a foreign corporation or a dealer in
securities. The Company will, from time to time, prepare and file such
statements and reports as are or may be required to continue such qualification
in effect for so long as the Underwriter may reasonably request.
    

   
     (c) So long as any of the Securities, the Option Securities or the
Underwriters' Securities remain outstanding in the hands of the public, the
Company, at its expense, will annually furnish to its shareholders a report of
its operations to include financial statements audited by independent public
accountants, and will furnish to the Underwriter as soon as practicable after
the end of each fiscal year, a balance sheet of the Company as at the end of
such fiscal year, together with statements of operations, shareholders' equity,
and changes in cash flow of the Company for such fiscal year, all in reasonable
detail and accompanied by a copy of the certificate or report thereon of
independent public accountants.
    

     (d) It will deliver to you at or before the Initial Closing Date three
signed copies of the Registration Statement including all financial statements
and exhibits filed therewith, whether or not incorporated by reference. The
Company will deliver to you, from time to time until the effective date of the
Prospectus, as many copies of the Prospectus as you may reasonably request. The
Company will deliver to you on the effective date of the Prospectus and
thereafter for so long as a Prospectus is required to be delivered under the Act
and the Rules and Regulations as many copies of the Prospectus, in final form,
or as thereafter amended or supplemented, as you may from time to time
reasonably request.

     (e) The Company will apply the net proceeds from the sale of the Securities
and the Option Securities substantially in the manner set forth under "Use of
Proceeds" in the Prospectus. No portion of the proceeds shall be used, directly

prior written consent of the Underwriter.

   
     (f) As soon as it is practicable, but in any event not later than the first

date of the Registration Statement, the Company will make available to its
security holders and the Underwriter an earnings statement (which need not be
audited) covering a period of at least twelve (12) consecutive months beginning

Regulations.
    

   
     (g) Non-Accountable Expense Allowance and other Costs and Expenses. The

from the purchase price for the Securities and the Option Securities, an amount
equal to three percent (3%) of the gross proceeds received by the Company from

in the case of the Initial Closing Date, the sum of $50,000 previously paid by
the Company. If the sale of the Securities by the Underwriter is not consummated
for any reason not attributable to the Underwriter, or if (i) the Company
withdraws the Registration Statement from the Commission or does not proceed
with the public offering, or (ii) the representations in Section 3 hereof are
not correct or the covenants cannot be complied with, or (iii) there has been a 
    
                                                                              10

materially adverse change in the condition, prospects or obligations of the
Company or a materially adverse change in stock market conditions from current
conditions, all as determined by the Underwriter, then the Company shall
reimburse the Underwriter for its out of pocket expenses including without
limitation, its legal fees and disbursements all on an accountable basis but not
to exceed $75,000 (less the $50,000 previously paid by the Company), and if any
excess remains from the advance previously paid, such excess will be returned to
the Company.

   
     (h) Costs and Expenses. Subject to the provisions above the Company will
pay all costs and expenses incident to the performance of this Agreement by the
Company including, but not limited to, the fees and expenses of counsel to the
Company and of the Company's accountants; the costs and expenses incident to the

     (i) As a condition of the closing, the Company shall obtain from its
officers and directors of the Company written commitments restricting the sale
of 100% of their common stock for (12) months after the closing.
    

   
     (j) During a date five years after the date hereof, the Company will make
available to its shareholders, as soon as practicable, and deliver to the
Underwriter:
    

         (1) as soon as they are available, copies of all reports (financial or
     other) mailed to shareholders;

         (4) any additional information of a public nature concerning the
     Company (and any future subsidiaries) or its businesses which the
     Underwriter may request.

     During such five-year period, if the Company has active subsidiaries, the
foregoing financial statements will be on a consolidated basis to the extent
that the accounts of the Company and its subsidiaries are consolidated, and will
be accompanied by similar financial statements for any significant subsidiary
which is not so consolidated.

   
     (k) The Company will maintain a Transfer Agent and, if necessary under the
jurisdiction of incorporation of the Company, a Registrar (which may be the same
entity as the Transfer Agent) for its Common Stock.
    

   
     (l) The Company will furnish to the Underwriters or on the Underwriters'
order, without charge, at such place as the Underwriters may designate, copies

soon as available and in such quantities as the Underwriters may request.
    

                                                                              11
<PAGE>   12

   
     (m) Neither the Company nor any of its officers, directors, stockholders or
any of its affiliates will take, directly or indirectly, any action designed to,
or which might in the future reasonably be expected to cause or result in
stabilization or manipulation of the price of any of the Company's securities.
    

   
     (n) The Company shall timely file all such reports, forms or other
documents as may be required from time to time, under the Act, the Exchange Act,
and the Rules and Regulations, and all such reports, forms and documents filed
will comply as to form and substance with the applicable requirements under the
Act, the Exchange Act, and the Rules and Regulations.
    

   
     (o) The Company shall cause the Securities to be listed on the NASDAQ Small
Cap Market or on an exchange for a period of five (5) years from the date
hereof, and use its best efforts to maintain the listing of the Securities to
the extent they are outstanding.
    

   
     (p) As soon as practicable, (i) before the effective date of the
Registration Statement, file a Form 8-A with the Commission providing for the
registration under the Exchange Act of the Securities and (ii) but in no event
more than 30 days from the effective date of the Registration Statement, take
all necessary and appropriate actions to be included in Standard and Poor's

indirectly, any press release or other communication or hold any press
conference with respect to the Company or its activities or the offering
contemplated hereby, other than trade releases issued in 'the ordinary course' 
of the Company's business consistent with past practices with respect to the
Company's operations.
    

   
     (r) Until the earlier of (i) five (5) years from the date hereof or (ii)
the sale to the public of the Warrant Shares, the Company will not take any
action or actions which may prevent or disqualify the Company's use of Form SB-2

     5. Conditions of the Underwriters' Obligations. The obligation of the
Underwriters to offer and sell the Securities and the Option Securities is
subject to the accuracy (as of the date hereof, and as of the Closing Dates) of
and compliance with the representations and warranties of the Company to the
performance by it of its agreement and obligations hereunder and to the
following additional conditions:
    

          (a) The Registration Statement shall have become effective as and when
     cleared by the Commission, and you shall have received notice thereof, on
     or prior to any closing date no stop order suspending the effectiveness of
     the Prospectus shall have been issued and no proceedings for that or
     similar purpose shall have been instituted or shall be pending, or, to your
     knowledge or to the knowledge of the Company, shall be contemplated by the
     Commission; any request on the part of the Commission for additional
     information shall have been complied with to the reasonable satisfaction of
     counsel to the Underwriter; and qualification, under the securities laws of
     such states as you may designate, of the issue and sale of the Securities
     upon the terms and conditions herein set forth or contemplated and
     containing no provision unacceptable to you shall have been secured, and no
     stop order shall be in effect denying or suspending effectiveness of such
     qualification nor shall any stop order proceedings with respect thereto be
     instituted or pending or threatened under such law.

          (b) On any closing date and, with respect to the letter referred to in
     subparagraph (iii), as of the date hereof, you shall have received:

   
               (i) the opinion, together with such number of signed or
          photostatic copies of such opinion as you may reasonably request,
          addressed to you by Jeffers, Wilson, Shaff & Falk, LLP, counsel for
          the Company, in form
    

                                                                              12

<PAGE>   13

          and substance reasonably satisfactory to the Underwriter and William
          M. Prifti, Esq., counsel to the Underwriter, dated each such closing
          date, to the effect that:

                    (A) The Company has been duly incorporated and is a validly
               existing corporation in good standing under the laws of the
               jurisdiction in which it is incorporated and has all necessary
               corporate power and authority to carry on its business as
               described in the Prospectus.

                    (B) The Company is qualified to do business in each
               jurisdiction in which conducting its business requires such
               qualification, except where the failure to be so qualified would
               not have a material adverse effect on the Company's business or
               assets.

   
                    (C) The Company has the full corporate power and authority
               to enter into this Agreement, the Underwriters' Warrant and to
               consummate the transactions provided for therein and each such
               Agreement has been duly and validly authorized, executed and
               delivered by the Company. Each of this Agreement and the
               Underwriters' Warrant, assuming due authorization, execution and
               delivery by each other party thereto, constitutes a legal, valid
               and binding agreement of the Company enforceable against the
               Company in accordance with its terms, subject to bankruptcy,
               insolvency or similar laws governing the rights of creditors and
               to general equitable principles, and provided that no opinion
               need be given as to the enforceability of any indemnification or
               contribution provisions, and none of the Company's execution or
               delivery of this Agreement, or the Underwriters' Warrant, its
               performance hereunder or thereunder, its consummation of the
               transactions contemplated herein or therein, or the conduct of
               its business as described in the Registration Statement, the
               Prospectus, and any amendments or supplements thereto, conflicts
               with or will conflict with or results or will result in any
               material breach or violation of any of the terms or provisions
               of, or constitutes or will constitute a material default under,
               or result in the creation or imposition of any material lien,
               charge, claim, encumbrance, pledge, security interest, defect or
               other restriction of any kind whatsoever upon, any property or
               assets (tangible or intangible) of the Company pursuant to the
               terms of (A) the articles of incorporation or by-laws of the
               Company, (B) to the knowledge of such counsel, any material
               license, contract, indenture, mortgage, deed of trust, voting
               trust agreement, stockholders' agreement, note, loan or credit
               agreement or any other agreement or instrument to which the
               Company is a party or by which it is or may be bound, or (C) to
               the knowledge of such counsel, any statute, judgment, decree,
               order, rule or regulation applicable to the Company, whether
               domestic or foreign.
    

                    (D) The Company had authorized and outstanding capital stock
               as set forth in the Prospectus under the heading "Capitalization"
               as of the date set forth therein, and all of such issued and
               outstanding shares of capital stock have been duly and validly
               authorized and issued, and to the knowledge of such counsel are
               fully paid and nonassessable, and to the knowledge of such
               counsel no stockholder of the Company is entitled to any
               preemptive rights to subscribe for, or purchase shares of the
               capital stock and to the knowledge of such counsel none of such
               securities were issued in violation of the preemptive rights of
               any holders of any securities of the Company.

   
                    (E) To the knowledge of such counsel, the Company is not a
               party to or bound by any instrument, agreement or other
               arrangement providing for it to issue any capital stock, rights,
               warrants, options or other securities, except for this Agreement,
               the Underwriters' Warrant, and except as described in the
               Prospectus. The Common Stock, the warrants and the Underwriters'
               Warrants each conforms in all material respects to the respective
               descriptions thereof contained in the Prospectus. The outstanding
               shares of Common Stock, the Underwriters' Warrants and the
               Warrant Shares, upon issuance and delivery and payment therefore
               in the manner described herein, in the Underwriters' Warrant and
               in the Underwriters' Agreement, as the case may be, will be duly
               authorized, validly issued, fully paid and nonassessable. There
               are no preemptive or other rights to subscribe for or to
               purchase, or any restriction upon the voting or transfer of, any
               shares of Common Stock pursuant to the Company's articles of
               incorporation, by-laws, other governing documents or any
               agreement or other instrument known to such counsel to which the
               Company is a party or by which it is bound. 
    

   
                    (F) The certificates representing the Securities comprising
               the Common Stock are in due and proper form and the Underwriters'
               Warrants have been duly authorized and reserved for issuance and
               when issued and delivered
    
                                                                              13
<PAGE>   14

   
               in accordance with the terms of the Underwriters' Warrant, will
               be duly and validly issued, fully paid and nonassessable.
    

                    (G) To the knowledge of such counsel, there are no claims,
               suits or other legal proceedings pending or threatened against
               the Company in any court or before or by any governmental body
               which might materially affect the business of the Company or the
               financial condition of the Company as a whole, except as set
               forth in or contemplated by the Prospectus.

                    (H) Based on oral and/or written advice from the staff of
               the Commission, the Registration Statement has become effective
               and, to the knowledge of such counsel, no stop order suspending
               the effectiveness of the Prospectus is in effect and no
               proceedings for that purpose are pending before, or threatened
               by, federal or by a state securities administrator.

   
                    (I) To the knowledge of such counsel, there are no legal or
               governmental proceedings, actions, arbitrations, investigations,
               inquiries or the like pending or threatened against the Company
               of a character required to be disclosed in the Prospectus which
               have not been so disclosed, questions the validity of the capital
               stock of the Company or this Agreement or the Underwriters'
               Warrant or might adversely affect the condition, financial or
               otherwise, or the prospects of the Company or which could
               adversely affect the Company's ability to perform any of its
               obligations under this Agreement, or the Underwriters' Warrant.
    

                    (J) To such counsel's knowledge, there are no material
               agreements, contracts or other documents known to such counsel
               required by the Act to be described in the Registration Statement
               and the Prospectus and filed as exhibits to the Registration
               Statement other than those described in the Registration
               Statement and the Prospectus and filed as exhibits thereto, and
               to such counsel's knowledge (A) the exhibits which have been
               filed are correct copies of the documents of which they purport
               to be copies; (B) the descriptions in the Registration Statement
               and the Prospectus and any supplement or amendment thereto of
               contracts and other documents to which the Company is a party or
               by which it is bound, including any document to which the Company
               is a party or by which it is bound incorporated by reference into
               the Prospectus and any supplement or amendment thereto, are
               accurate in all material respects and fairly represent the
               information required to be shown by Form SB-2.

   
                    (K) No consent, approval, order or authorization from any
               regulatory board, agency or instrumentality having jurisdiction
               over the Company, or its properties (other than registration
               under the Act or qualification under state or foreign securities
               law or approval by the NASD) is required for the valid
               authorization, issuance, sale and delivery of the Securities, the
               Option Securities or the Underwriters' Warrant.
    

   
                    (L) The statements in the Prospectus under "Risk Factors-
               Dependence on Key Personnel and Consultants, Control by Existing
               Shareholders," "Indemnification of Officers and Directors,"
               "Description of the Securities," and "Shares Eligible For Future
               Sale" have been reviewed by such counsel, and insofar as they
               refer to statements of law, descriptions of statutes, licenses,
               rules or regulations or legal conclusions, are correct in all
               material respects.
    

   
                    In addition, such counsel shall state that such counsel has
               participated in conferences with officials and other
               representatives of the Company, the Underwriters, Underwriter's
               Counsel and the independent certified public accountants of the
               Company, at which such conferences the contents of the
               Registration Statement and Prospectus and related matters were
               discussed, and although they have not certified the accuracy or
               completeness of the statements contained in the Registration
               Statement or the Prospectus, nothing has come to the attention of
               such counsel which leads them to believe that, at the time the
               Registration Statement became effective and at all times
               subsequent thereto up to and on the Closing Date and on any later
               date on which Option Shares are to be purchased, the Registration
               Statement and any amendment or supplement, when such documents
               became effective or were filed with the Commission (other than
               the financial 
    

                                                                              14
<PAGE>   15

               statements including the notes thereto and supporting schedules
               and other financial and statistical information derived
               therefrom, as to which such counsel need express no comment)
               contained any untrue statement of a material fact or omitted to
               state a material fact required to be stated therein or necessary
               to make the statements therein not misleading, or at the Closing
               Date or any later date on which the Option Shares are to be
               purchased, as the case may be, the Prospectus and any amendment
               or supplement thereto (other than the financial statements
               including the notes thereto and other financial and statistical
               information derived therefrom, as to which such counsel need
               express no comment) contained any untrue statement of a material
               fact or omitted to state a material fact necessary to make the
               statements therein, in the light of the circumstances under which
               they were made, not misleading.

                    Such opinion shall also cover such other matters incident to
               the transactions contemplated hereby and the offering Prospectus
               as you or counsel to the Underwriter shall reasonably request. In
               rendering such opinion, to the extent deemed reasonable by them,
               such counsel may rely upon certificates of any officer of the
               Company or public officials as to matters of fact of which the
               maker of such certificate has knowledge.

   
               (ii) a certificate, signed by the Chief Executive Officer and the
          Chief Financial Officer of the Company dated the Closing Date, to the
          effect that with regard to the Company, each of the conditions set
          forth in Section 5(d) have been satisfied.
    

   
               (iii) a letter, addressed to the Underwriter and in form and
          substance satisfactory to the Underwriter in all respects (including
          the nonmaterial nature of the changes or decreases, if any, referred
          to in clause (D) below), from, Singer Lewak Greenbaum & Goldstein LLP
          dated, respectively, as of the effective date of the Registration
          Statement and as of the Closing Date, as the case may be:
    

                    (A) Confirming that they are independent public accountants
               with respect to the Company and its consolidated subsidiaries, if
               any, within the meaning of the Act and the applicable published
               Rules and Regulations.

                    (B) Stating that, in their opinion, the financial
               statements, related notes and schedules of the Company and its
               consolidated subsidiaries, if any, included in the Registration
               Statement examined by them comply as to form in all material
               respects with the applicable accounting requirements of the Act
               and the published Rules and Regulations thereunder.

   
                    (C) Stating that, with respect to the period from December
               31, 1996, to a specified date (the specified date") not earlier
               than five (5) business days prior to the date of such letter,
               they have read the minutes of meetings of the shareholders and
               board of directors (and various committees thereof) of the
               Company and its consolidated subsidiaries, if any, for the period
               from December 31, 1996 through the specified date, and made
               inquiries of officers of the Company and its consolidated
               subsidiaries, if any, responsible for financial and accounting
               matters and, especially as to whether there was any decrease in
               sales, income before extraordinary items or net income as
               compared with the corresponding period in the preceding year; or
               any change in the capital stock of the Company or any change in
               the longterm debt or any increase in the short-term bank
               borrowings or any decrease in net current assets or net assets of
               the Company or of any of its consolidated subsidiaries, if any,
               and further stating that while such procedures and inquiries do
               not constitute an examination made in accordance with generally
               accepted auditing standards, nothing came to their attention
               which caused them to believe that during the period from December
               31, 1996, through the specified date there were any decreases as
               compared with the corresponding period in the preceding year in
               sales, income before extraordinary items or net income; or any
               change in the capital stock of the Company or consolidated
               subsidiary, if any, or any change in the long term debt or any
               increase in the short-term bank borrowings (other than any
               increase in short-term bank borrowings in the ordinary course of
               business) of the Company or any consolidated subsidiary, if any,
               or any decrease in the net current assets or net assets of the
               Company or any consolidated subsidiary, if any; and
    

   
                    (D) Stating that they have carried out certain specified
               procedures (specifically set forth in such letter or letters) as
               specified by the Underwriter (after consultations with Singer
               Lewak Greenbaum & Goldstein LLP relating to such procedures),
               not constituting an audit, with respect to certain tables,
               statistics and other financial data in the Prospectus specified
               by the Underwriter and such financial data not included in the
               Prospectus but from which information in the Prospectus is
               derived, and which have been obtained from the general accounting
               records of the Company or consolidated subsidiaries, if any, or
               from such accounting records by analysis or computation, and
               having compared such financial data with the accounting records
               of the Company or the consolidated subsidiaries, if any, stating
               that they have found such financial data to agree with the
               accounting records of the Company.
    

                                                                              15

          (c) All corporate proceedings and other legal matters relating to this
     Agreement, the Prospectus and other related matters shall be satisfactory
     to or approved by counsel to the Underwriter and you shall have received
     from Jeffers, Wilson, Shaff & Falk, LLP a signed opinion dated as of each
     closing date, with respect to the incorporation of the Company, the
     validity of the Securities, the form of the Prospectus, (other than the
     financial statements together with related notes and other financial and
     statistical data contained in the Prospectus or omitted therefrom, as to
     which such counsel need express no opinion), the execution of this
     Agreement and other related matters as you may reasonably require.

          (d) At each closing date, (i) the representations and warranties of
     the Company contained in this Agreement shall be true and correct in all
     material respects with the same effect as if made on and as of such closing
     date; (ii) the Prospectus and any amendments or supplements thereto shall
     contain all statements which are required to be stated therein in
     accordance with the Act and the Rules and Regulations and in all material
     respects conform to the requirements thereof, and neither the Prospectus
     nor any amendment or supplement thereto shall contain any untrue statement
     of a material fact or omit to state any material fact required to be stated
     therein or necessary, in light of the circumstances under which they were
     made, in order to make the statements therein not misleading; (iii) there
     shall have been since the respective dates as of which information is given
     no material adverse change in the business, properties or condition
     (financial or otherwise), results of operations, capital stock, longterm
     debt or general affairs of the Company from that set forth in the
     Prospectus, except changes which the Prospectus indicates might occur after
     the effective date of the Prospectus, and the Company shall not have
     incurred any material liabilities or material obligations, direct or
     contingent, or entered into any material transaction, contract or agreement
     not in the ordinary course of business other than as referred to in the
     Prospectus and which would be required to be set forth in the Prospectus;
     and (iv) except as set forth in the Prospectus, no action, suit or
     proceeding at law or in equity shall be pending or threatened against the
     Company which would be required to be set forth in the Prospectus, and no
     proceedings shall be pending or threatened against the Company or any
     subsidiary before or by any commission, board or administrative agency in
     the United States or elsewhere, wherein an unfavorable decision, ruling or
     finding would materially and adversely affect the business, property,
     condition (financial or otherwise), results of operations or general
     affairs of the Company.

   
          (e) On the Initial Closing Date, the Company shall have executed and
     delivered to the Underwriter, (i) the Underwriters' Warrant substantially

     and substance satisfactory to the Underwriter, and (ii) the Underwriters'
     Warrants in such denominations and to such designees as shall have been
     provided to the Company.

     delivered pursuant to Section 3(a)(xxv) and 4(h), in form and substance
     satisfactory to the Underwriter and Underwriter's counsel.

   
     If any condition to the Underwriters' obligations hereunder to be fulfilled
prior to or at the Initial Closing Date or the relevant Option Closing Date, as
the case may be, is not so fulfilled, the Underwriter may terminate this
Agreement or, if the Underwriter so elects, it may waive any such conditions
which have not been fulfilled or extend the time for their fulfillment.
    

     6. Conditions of the Company's Obligations. The obligation of the Company

          (a) The provisions regarding the effective date, as described in
     Section 10.

          (b) At the Initial Closing Date, no stop order suspending the

7.  Indemnification.

   
     (a) The Company agrees to indemnify and hold harmless each Underwriter and
its employees and each person, if any, who controls you within the meaning of
the Act, against any losses, claims, damages or liabilities, joint or several
(which shall, for any purposes of this Agreement, include, but not be limited
to, all costs of defense and investigation and all attorneys' fees), to which
each Underwriter or such controlling person may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission made in the Prospectus, or such amendment or supplement to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, which is in reliance upon and in conformity
with written information furnished by the Company to you specifically for use in
the preparation thereof, and provided further that the indemnity agreement
contained in this subsection (a) shall not inure to the benefit of you with
respect to any person asserting any such loss, claim, damage or liability who
has purchased the Securities which are the subject thereof if you or any
participants failed to send or give a copy of the Prospectus to such person at
or prior to the written confirmation of the sale of such Securities to such
person and except that, with respect to any untrue statement or omission or any
alleged untrue statement or omission, made in any Pre-Effective Prospectus, the
indemnity agreement contained in this subsection (a) shall not inure to the
benefit of any Underwriter (or to any person controlling any such underwriter)
from whom the person asserting any such loss, claim, damage or liability
purchased the securities concerned to the extent that such untrue statement or
omission, or alleged untrue statement or omission, has been corrected in a later
Pre-Effective Prospectus or in the Final Prospectus unless the Underwriter
circulated a later Pre-Effective Prospectus or the Final Prospectus to such
person.
    

     (b) Each Underwriter will indemnify and hold harmless the Company, each of
its directors, each of its officers, each person, if any, who controls the
Company within the meaning of the Act against any losses, claims, damages or
liabilities, joint or several (which shall, for all purposes of this Agreement,
include, but not be limited to, all costs of defense and investigation and all
attorneys' fees) to which the Company or any such director, officer or
controlling person may become subject under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or the alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, in each case to the extent, but only
to the extent, that such untrue statement or alleged untrue statement or
omission was made in the Prospectus, or such amendment or supplement, in
reliance upon and in conformity with written information furnished to the
Company by you specifically for use in the preparation thereof. This indemnity
will be in addition to any liability which any Underwriter may otherwise have.

     (c) Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section, notify the indemnifying party of the commencement thereof, but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section. In case any such action is brought against any indemnified party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party, similarly notified, to assume the
defense thereof, subject to the provisions herein stated, with counsel
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party
under this Section for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. The indemnified party shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall not be at the expense of the
indemnifying party if the indemnifying party has assumed the defense of the
action with counsel reasonably satisfactory to the indemnified party; provided
that, if the indemnified party is you or a person who controls you, the fees and
expenses of such 

                                                                              17
<PAGE>   18

counsel shall be at the expense of the indemnifying party if (i) the employment
of such counsel has been specifically authorized in writing by the indemnifying
party or (ii) the named parties to any such action (including any impleaded
parties) include both you or such controlling person and the indemnifying party
and you or such controlling person shall have been advised by such counsel that
there is a conflict of interest which would prevent counsel for the indemnifying
party from representing the indemnifying party and you or such controlling
person (in which case the indemnifying party shall not have the right to assume
the defense of such action on behalf of you or such controlling person, it being
understood, however, that the indemnifying party shall not, in connection with
any one such action or separate but substantially similar or related actions in
the same jurisdiction or which are consolidated into the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys for you
and all such controlling persons, which firm shall be designated in writing by
you). No settlement of any action against an indemnified party shall be made
without the consent of the indemnified party, which shall not be unreasonably
withheld in light of all factors of importance to such indemnified party.

   
     8. Contribution. In order to provide for just and equitable contribution
tinder the Act in any case in which (i) the indemnifying party makes a claim for
indemnification pursuant to Section 7 hereof but it is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that the express provisions of Section 7 provide for indemnification in such
case, or (ii) contribution under the Act may be required on the part of the
Underwriters, then the Company and the Underwriters in the aggregate shall
contribute to the aggregate losses, claims, damages, or liabilities to which
they may be subject (which shall, for all purposes of this Agreement, include,
but not be limited to, all costs of defense and investigation and all attorneys'
fees) in either such case (after contribution from others) in such proportions
that the Underwriters are responsible in the aggregate for that portion of such
losses, claims, damages or liabilities determined by multiplying the total
amount of such losses, claims, damages or liabilities times the difference
between the public offering price and the commission to the Underwriters and
dividing the product thereof by the public offering price, and the Company, if
applicable, shall be responsible for that portion of such losses, claims,
damages or liabilities times the commission to the Underwriters and dividing the
product thereof by the public offering price; provided, however, that the
Underwriters shall not be required to so contribute any amount in excess of the
underwriting discount applicable to the Securities purchased by the Underwriters
hereunder if such allocation is not permitted by applicable law, then the
relative fault of the Company and the Underwriters in connection with the
statements or omissions which resulted in such damages and other relevant
equitable considerations shall also be considered. No person guilty of a
fraudulent misrepresentation (within the meaning of Section 12(2) of the Act)
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation. The foregoing contribution agreement shall in no
way affect the contribution liabilities of any person having liability under
Section 12 of the Act other than the Company and the Underwriter. As used in
this paragraph, the term "Underwriters" includes any person who controls the
Underwriters within the meaning of Section 15 of the Act. If the full amount of
the contribution specified in this paragraph is not permitted by law, then any
Underwriter and each person who controls any Underwriter shall be entitled to
contribution from the Company, to the full extent permitted by law.
    

     9. Effective Date. This Agreement shall become effective at 10:00 a.m. New
York time on the next full business day following the effective date of the
Registration Statement, or at such other time after the effective date of the
Prospectus as you in your discretion shall first commence the public offering of
any of the Securities covered thereby, provided, however, that at all times the
provisions of Sections 7, 8, 9 and 11 shall be effective.

     10.  Termination.

     (a) This Agreement, may be terminated at any time prior to the Closing Date
by you if in your judgment it is impracticable to offer for sale or to enforce
contracts made by you for the sale of the Securities agreed to be sold hereunder
by reason of (i) the Company as a whole having sustained a material loss,
whether or not insured, by reason of fire, earthquake, flood, accident or other
calamity, or from any labor dispute or court or government action, order or
decree, (ii) trading in securities of the Company having been suspended by a
state securities administrator or by the Commission, (iii) material governmental
restrictions having been imposed on trading in 

                                                                             18
<PAGE>   19

   
securities generally (not in force and effect on the date hereof) or trading on
the New York Stock Exchange, American Stock Exchange, or in the over-the-counter
market shall have been suspended, (iv) a banking moratorium having been declared
by federal or New York State authorities, (v) an outbreak or escalation of
hostilities or other national or international calamity having occurred, (vi)
the passage by the Congress of the United States or by any state legislative
body, of any act or measure, or the adoption of any orders, rules or regulations
by any governmental body or any authoritative accounting institute or board, or
any governmental executive, which is believed likely by you to have a material
impact on the business, financial condition or financial statements of the
Company; or (vii) any material adverse change having occurred, since the
respective dates as of which information is given in the Prospectus, in the
condition, financial or otherwise, of the Company as a whole, whether or not
arising in the ordinary course of business, (viii) Paul J. White, Kenneth S.
Kornman and Michael G. Newman cease to be employed by the Company in their
present capacity; (ix) the Securities are not listed the American Stock Exchange
or any other exchange or on NASDAQ.
    

     (b) If you elect to prevent this Agreement from becoming effective or to
terminate this Agreement as provided in this Section 10 or in Section 9, the
Company shall be promptly notified by you, by telephone or telegram, confirmed
by letter.

   
     11. Representations, Warrants and Agreements to Survive Delivery. The
respective indemnities, agreements, representations, warranties and other
statements of the Company (or its officers) and the Underwriters set forth in or
made pursuant to this Agreement will remain in full force and effect, regardless
of any investigation made by or on behalf of the Underwriters, the Company, or
any of their officers or directors and will survive delivery of and payment for
the Securities.
    

   
     12. Notices. All communications hereunder will be in writing and, except as
otherwise expressly provided herein, if sent to you, will be mailed, delivered
or telephoned and confirmed to you at, Nutmeg Securities, Ltd., 495 Post Road

Division; to the Company at 4400 MacArthur Boulevard, Suite 980, Newport Beach,

     13. Parties in Interest. This Agreement is made solely for the benefit of
the Underwriter(s), and the Company, and their respective controlling persons,
directors and officers, and their respective successors, assigns, executors and
administrators. No other person shall acquire or have any right under or by
virtue of this Agreement.
    

     14. Headings. The Section headings in this Agreement have been inserted as
a matter of convenience of reference and are not a part of this Agreement.

     15. Applicable Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Connecticut, without giving effect to
conflict of law principles.

     16. Counterparts. This Agreement may be executed in any number of
counterparts, each of which together shall constitute one and the same
instrument.

                                                                             19

                                                                        , 19

as Representative
    


GENTLEMEN:

   
     We wish to confirm as follows the agreement among you, the undersigned and
the other members of the Underwriting Group named in Schedule I to the
Underwriting Agreement, as it is to be executed (all such parties being herein
called the "Underwriters"), with respect to the purchase by the Underwriters
severally from Medical Science Systems, Inc. ("Company") of 2,500,000 shares of
Common Stock ("Securities") set forth in Schedule I to the Underwriting
Agreement. The number of Securities to be purchased by each Underwriter from the
Company shall be determined in accordance with Section 2 of the Underwriting
Agreement. It is understood that changes may be made in those who are to be
Underwriters and in the respective numbers of Securities to be purchased by
them, but that the Underwriting Agreement will not be changed without our
consent, except as provided herein, and in the Underwriting Agreement. The
obligations of the Underwriters to purchase the number of Securities set
opposite their respective names in Schedule I to the Underwriting Agreement, are
herein called their "underwriting obligations." The number of Securities set
opposite our name in said Schedule I, are herein called "our Securities." For
purposes of this Agreement the following definitions shall be applicable:
    

     (a) "Manager's Concession" shall be the compensation to you for acting as
Manager as provided in Paragraph 1 of not less than     percent (   %) of the
underwriting discount. The Manager's Concession shall include the right to a
portion of the warrants to be issued pursuant to the Underwriting Agreement and,
the right to the nonaccountable expenses to be paid pursuant to the Underwriting
Agreement.

     (b) "Underwriting Group Concession" shall mean compensation to members of
the Underwriting Group for assuming the underwriting risk and shall be not less
than percent ( %) of the underwriting discount.

     (c) "Dealer's Concession" shall mean compensation to Dealers, who are
members of the Selling Group and shall, as to Dealers who have executed an
agreement with you, be not less than    percent (   %) of the underwriting 
discount.

     (d) "Dealer's Reallowance Concession" shall mean the compensation allowed
Dealers by Underwriters other than you and shall be one-half (1/2) of the
Dealer's Concession.

   
     (e) It is contemplated that the underwriting discount will be ten percent
(10%) of the offering price. You, in your absolute discretion, shall determine,
within the foregoing limitations, the precise allocation of the underwriting
discount and shall notify us of the same at least twenty-four (24) hours prior 
to the execution of the Underwriting Agreement.
    

     1. Authority and Compensation of Representative. We hereby authorize you,
as our Representative and on our behalf, (a) to enter into an agreement with the
Company substantially in the form attached hereto as Exhibit A ("Underwriting
Agreement"), but with such changes therein as in your judgment are not
materially adverse to the Underwriters, (b) to exercise all the authority and
discretion vested in the Underwriters and in you by the provisions 


                                                                               1

<PAGE>   2

of the Underwriting Agreement, and (c) to take all such action as you, in your
discretion, may deem necessary or advisable in order to carry out the provisions
of the Underwriting Agreement and this Agreement and the sale and distribution
of the Securities, provided, however, that the time within which the
Registration Statement is required to become effective pursuant to the
Underwriting Agreement will not be extended more than forty-eight (48) hours
without the approval of a majority in interest of the Underwriters (including
you). We authorize you, in executing the Underwriting Agreement on our behalf,
to set forth in Schedule I of the Underwriting Agreement as our commitment to
purchase the number of Securities (which shall not be substantially in excess of
the number of Securities included in your invitation to participate unless we
have agreed otherwise) included in a wire, telex, or similar means of
communication transmitted by you to us at least twenty-four (24) hours prior to
the commencement of the offering as our finalized underwriting participation.

     As our share of the compensation for your services hereunder, we will pay
you, and we authorize you to charge to our account, a sum equal to the Manager's
Concession.
     
     2. Public Offering. A public offering of the Securities is to be made, as
herein provided, as soon after the Registration Statement relating thereto shall
become effective as in your judgment is advisable. The Securities shall be
initially offered to the public at the public offering price of $     per share.
You will advise us by telegraph or telephone when the Securities shall be
released for offering. We authorize you as Representative of the Underwriters,
after the initial public offering, to vary the public offering price, in your
sole discretion, by reason of changes in general market conditions or otherwise.
The public offering price of the Securities at any time in effect is herein
called the "Offering Price."

     We hereby agree to deliver all preliminary and final Prospectuses as
required for compliance with the provisions of Rule 15c2-8 under the Securities
Exchange Act of 1934 and Section 5(b) of the Securities Act of 1933. You have
heretofore delivered to us such preliminary Prospectuses as have been requested
by us, receipt of which is hereby acknowledged, and will deliver such final
Prospectuses as will be requested by us.

     3. Offering to Dealers and Group Sales. We authorize you to reserve for
offering and sale, and on our behalf to sell, to institutions or other retail
purchasers (such sales being herein called "Group Sales") and to dealers
selected by you (such dealers being herein called the "Dealers") all or any part
of our Securities as you may determine. Such sales of Securities, if any, shall
be made (i) in the case of Group Sales, at the Offering Price, and (ii) in the
case of sales to Dealers, at -the Offering Price less the Dealer's Concession.

     Any Group Sales shall be as nearly as practicable in proportion to the
underwriting obligations of the respective Underwriters. Any sales to Dealers
made for our account shall be as nearly as practicable in the ratio that the
Securities reserved for our account for offering to Dealers bears to the
aggregate of all Securities of all Underwriters, including you, so reserved. On
any Group Sales or sales to Dealers made by you on our behalf, we shall be
entitled to receive only the Underwriter's Concession.

     You agree to notify us not less than twenty-four (24) hours prior to the
commencement of the public offering as to the number of Securities, if any,
which we may retain for direct sale. Prior to the termination of this Agreement,
you may reserve for offering and sale, as herein before provided, any Securities
remaining unsold theretofore retained by us and we may, with your consent,
retain any Securities remaining unsold theretofore reserved by you. Sales to
Dealers shall be made under a Selected Dealers Agreement, attached hereto as
Exhibit B and by this reference incorporated herein. We authorize you to
determine the form and manner of any communications with Dealers, and to make
such changes in the Selected Dealers Agreement, as you may deem appropriate. In
the event that there shall be any such agreements with Dealers, you are
authorized to act as managers thereunder, and we agree, in such event, to be
governed by the terms and conditions of such agreements. Each Underwriter agrees
that it will not offer any of the Securities for sale at a price below the
Offering Price or allow any concession therefrom, except as herein otherwise
provided. We, as to our Securities, may enter into agreements with Dealers, but
any Dealer's Reallowance Concession shall not exceed half of the Dealer's
Concession.

     It is understood that any person to whom an offer may be made, as herein
before provided, shall be a member of the National Association of Securities
Dealers, Inc. ("NASD") or dealers or institutions with their principal place of


                                                                               2


<PAGE>   3

business located outside of the United States, its territories or possessions,
and who are not eligible for membership under Section 1 of the Bylaws of the
NASD who agree to make no sales within the United States, its territories or
possessions, or to persons who are nationals thereof, or residents therein, and,
in making sales, to comply with the NASD's Rules of Fair Practice.

     We authorize you to determine the form and manner of any public
advertisement of the Securities.

   
     Nothing contained in this Agreement shall be deemed to restrict our right,
subject to the provisions of this Section 3, to offer our Securities prior to
the effective date of the Registration Statement, provided, however, that any
such offer shall be made in compliance with any applicable requirements of the
Securities Act of 1933 and the Securities Exchange Act of 1934 and the rules and
regulations of the Securities and Exchange Commission thereunder and of any
applicable state securities laws.
    

     4. Repurchases in the Open Market. Any Securities sold by us (otherwise
than through you) which, prior to the termination of this Agreement, or such
earlier date as you may determine, shall be contracted for or purchased in the
open market by you on behalf of any Underwriter or Underwriters, shall be
repurchased by us on demand at a price equal to the cost of such purchase plus
commissions and taxes, if any, on redelivery. Any Securities delivered on such
repurchase need not be the identical Securities originally sold by us. In lieu
of delivery of such Securities to us, you may (i) sell such Securities in any
manner for our account and charge us with the amount of any loss or expense, or
credit us with the amount of any profit, less any expense, resulting from such
sale, or (ii) charge our account with an amount not in excess of the concession
to Dealers on such Securities.

   
     5. Delivery and Payment. We agree to deliver to you, at or before 9:00
A.M., New York, New York Time, on the Initial Closing Date referred to in the
Underwriting Agreement, at your office, a certified or bank cashier's check
payable to your order for the offering price of the Securities less Dealer's
Concession of the Securities which we retained for direct sale by us, the
proceeds of which check shall be delivered to you, in the manner provided in the
Underwriting Agreement, to or for the account of the Company against delivery of
certificates for such Securities to you for our account. You are authorized to
accept such delivery and to give receipts therefor. You may advance funds for
Securities which have been sold or reserved for sale to retail purchasers or
Dealers for our account. If we fail (whether or not such failure shall
constitute a default hereunder) to deliver to you, or you fail to receive, our
check and/or payment for sales made by you for our account for the Securities
which we have agreed to purchase, you, individually and not as Representative of
the Underwriters, are authorized (but shall not be obligated) to make payment,
in the manner provided in the Underwriting Agreement, to or for the account of
the Company for such Securities for our account, but any such payment by you
shall not relieve us of any of our obligations under the Underwriting Agreement
or under this Agreement and we agree to repay you on demand the amount so
advanced for our account.
    

     We also agree on demand to take up and pay for or to deliver to you funds
sufficient to pay for at cost any Securities of the Company purchased by you for
our account pursuant to the provisions of Section 9 hereof, and to deliver to
you on demand any Securities sold by you for our account, pursuant to any
provision of this Agreement.

     We authorize you to deliver our Securities, and any other Securities
purchased by you for our account pursuant to the provisions of Section 9 hereof,
against sales made by you for our account pursuant to any provision of this
Agreement.

   
     Upon receipt by you of payment for the Securities sold by us and/or through
you for our account, you will remit to us promptly an amount equal to the
Underwriter's Concession on such Securities. You agree to cause to be delivered
to us, as soon as practicable after the Closing Date referred to in the
Underwriting Agreement, such part of our Securities purchased on such Closing
Date as shall not have been sold or reserved for sale by you for our account.
    

     In case any Securities reserved for sale in Group Sales or to Dealers shall
not be purchased and paid for in due course as contemplated hereby, we agree to
accept delivery when tendered by you of any Securities so reserved for our
account and not so purchased and pay you the offering price less the Dealer's
and Underwriter's Concessions.


                                                                               3


<PAGE>   4

     6. Authority to Borrow. We authorize you to advance your funds for our
account (charging current interest rates) and to arrange loans for our account
for the purpose of carrying out this Agreement, and in connection therewith to
execute and deliver any notes or other instruments, and to hold, or pledge as
security therefor, all or any part of our Securities of the Company purchased
hereunder for our account. Any lending bank is hereby authorized to accept your
instructions as Representative in all matters relating to such loans. Any part
of our Securities held by you, may be delivered to us for carrying purposes, and
if so delivered, will be redelivered to you upon demand.

     7. Allocation of Expense and Liability. We authorize you to charge our
account with, and we agree to pay (a) all transfer taxes on sales made by you
for our account, except as herein otherwise provided, and (b) our proportionate
share (based on our underwriting obligations) of all expenses in excess of those
reimbursed by the Company incurred by you in connection with the purchase,
carrying and distribution, or proposed purchase and distribution, of the
Securities and all other expenses arising under the terms of the Underwriting
Agreement or this Agreement. Your determination of all such expenses and your
allocation thereof shall be final and conclusive. Funds for our account at any
time in your hands as our Representative may be held in your general funds
without accountability for interest. As soon as practicable after the
termination of this Agreement, the net credit or debit balance in our account,
after proper charge and credit for all interim payments and receipts, shall be
paid to or paid by us, provided, however, that you, in your discretion, may
reserve from distribution an amount to cover possible additional expenses
chargeable to the several Underwriters.

     8. Liability for Future Claims. Neither any statement by you, as
Representative of the Underwriters, of any credit or debit balance in our
account nor any reservation from distribution to cover possible additional
expenses relating to the Securities shall constitute any representation by you
as to the existence or nonexistence of possible unforeseen expenses or
liabilities of or charges against the several Underwriters. Notwithstanding the
distribution of any net credit balance to us or the termination of this
Agreement, or both, we shall be and remain liable for, and will pay on demand,
(a) our proportionate share (based on our underwriting obligations) of all
expenses and liabilities which may be incurred by, or for the accounts of the
Underwriters, including any liability which may be incurred by the Underwriters
or any of them, and (b) any transfer taxes paid after such settlement on account
of any sale or transfer for our account.

     9. Stabilization. We authorize you, until the termination of this
Agreement, (a) to make purchases and sales of the Securities, in the open market
or otherwise, for long or short account, and on such terms, and at such prices
as you in your discretion may deem desirable, (b) in arranging for sales of
Securities, to overallot, and (c) either before or after the termination of this
Agreement, to cover any short position incurred pursuant to this Section 9;
subject, however, to the applicable rules and regulations of the Securities and
Exchange Commission under the Securities Exchange Act of 1934. All such
purchases, sales and overallotments shall be made for the accounts of the
several Underwriters as nearly as practicable in proportion to their respective
underwriting obligations; provided, however, that our net position resulting
from such purchases and sales and overallotments shall not at any time exceed,
either for long or short account, fifteen percent (15%) of the number of
Securities agreed to be purchased by us.

     If you engage in any stabilizing transactions as representative of the
underwriters, you shall promptly notify us of that fact and in like manner you
agree to promptly notify and file with us any stabilizing transaction in
accordance with the requirements of Rule 17a-2(d) under the Securities Exchange
Act of 1934.

We agree to advise you from time to time, upon request, until the settlement of
accounts hereunder, of the number of Securities at the time retained by us
unsold, and we will upon request sell to you, for the accounts of one or more of
the several Underwriters, such number of our unsold Securities as you may
designate, at the Offering Price less such amount, not in excess of the
concession to Dealers, as you may determine.

     10. Open Market Transactions. We agree that, except with your consent and
except as herein provided upon advice from you, we will not make purchases or
sales on the open market or otherwise, or attempt to induce others to make
purchases or sales, either before or after the purchase of the Securities, and
prior to the completion (as defined in Regulation M of the Securities Exchange
Act of 1934) of our participation in the distribution, we will otherwise 


                                                                               4


<PAGE>   5

comply with Regulation M. Nothing in this Section 10 contained shall prohibit us
from acting as broker or agent in the execution of unsolicited orders of
customers for the purchase or sale of any securities of the Company.

     11. Blue Sky. Prior to the initial offering by the Underwriters, you will
inform us as to the states under the respective securities or Blue Sky laws of
which it is believed that the Securities have been qualified or are exempt for
sale, but you do not assume any responsibility or obligation as to the accuracy
of such information or as to the right of any Underwriter or Dealer to sell the
Securities in any jurisdiction. We will not sell any Securities in any other
state or jurisdiction and we will not sell Securities in any state or
jurisdiction unless we are qualified or licensed to sell securities in such
state or jurisdiction. We authorize you, if you deem it inadvisable in arranging
sales of Securities for our account hereunder, to sell any of our Securities to
any particular Dealer, or other buyer, because of the securities or Blue Sky
laws of any jurisdiction, to sell our Securities to one or more other
Underwriters at the Offering Price less, in the case of a sale to any Dealer,
such amount, not in excess of the concession to Dealers thereon, as you may
determine. The transfer tax on any such sales among Underwriters shall be
treated as an expense and charged to the respective accounts of the several
Underwriters, in proportion to their respective underwriting obligations.

     12. Default by Underwriters. Default by one or more Underwriters, in
respect to their obligations under the Underwriting Agreement shall not release
us from any of our obligations. In case of such default by one or more
Underwriters, you are authorized to increase, pro rata, with the other
nondefaulting Underwriters, the number of defaulted Securities which we shall be
obligated to purchase from the Company, provided, however, that the aggregate
amount of all such increases for all Underwriters shall not exceed ten percent
(10%) of such Securities, and, if the aggregate number of the Securities not
taken up by such defaulting Underwriters exceeds such ten percent (10%), you are
further authorized, but shall not be obligated, to arrange for the purchase by
other persons, who may include yourselves, of all or a portion of the Securities
not taken up by such Underwriters. In the event any such increases or
arrangements are made, the respective numbers of Securities to be purchased by
the nondefaulting Underwriters and by any such other person or persons shall be
taken as the basis for the underwriting obligations under this Agreement, but
this shall not in any way affect the liability of any defaulting Underwriters to
the other Underwriters for damages resulting from such default.

     In the event of default by one or more Underwriters in respect of their
obligations under this Agreement to take up and pay for any Securities purchased
by your for their respective accounts, pursuant to Section 9 hereof, or to
deliver any such Securities sold or overallotted by you for their respective
accounts pursuant to any provisions of this Agreement, and to the extent that
arrangements shall not have been made by you for other persons to assume the
obligations of such defaulting Underwriter or Underwriters, each nondefaulting
Underwriter shall assume its proportionate share of the aforesaid obligations of
each such defaulting Underwriter without relieving any such Underwriter of its
liability therefor.

   
     13. Termination of Agreement. Unless earlier terminated by you, the
provisions of Sections 2, 3, 4, 6, 9 and 10 of this Agreement shall, except as
otherwise provided therein, terminate thirty (30) full business days after the
effective date of the Registration Statement herein referred to, but may be
extended by you for an additional period or periods not exceeding thirty (30)
full business days in the aggregate. Except as otherwise provided, you may
terminate this Agreement, or any provisions hereof, at any time by written or
telegraphic notice to us.
    

     14. General Position of the Representative. In taking action under this
Agreement, you shall act only as agent of the several Underwriters. Your
authority as Representative of the several Underwriters shall include the taking
of such action as you may deem advisable in respect of all matters pertaining to
any and all offers and sales of the Securities, including the right to make any
modifications which you consider necessary or desirable in the arrangements with
Dealers or others. You shall be under no liability for or in respect of the
value of the Securities or the validity or the form thereof, the Registration
Statement, the Prospectus, the Underwriting Agreement, or other instruments
executed by the Company or others of any agreement on its or their part; nor
shall you, as such Representative or otherwise, be liable under any of the
provisions hereof, or for any matters connected herewith, except for want of
good faith, and except for any liability arising under the Securities Act of
1933; and no obligation not expressly assumed by you as such Representative
herein shall be implied from this Agreement. In representing the Underwriters
hereunder, you shall act as the representative of each of them respectively.
Nothing herein contained shall constitute the several Underwriters partners with
you or with each other, or render any Underwriter


                                                                               5


<PAGE>   6

liable for the commitments of any other Underwriter, except as otherwise
provided in Section 12 hereof. The commitments and liabilities of each of the
several Underwriters are several in accordance with their respective
underwriting obligations and are not joint.

     15. Acknowledgment of Registration Statement, etc. We hereby confirm that
we have examined the Registration Statement (including all amendments thereto)
relating to the Securities as heretofore filed with the Securities and Exchange
Commission, that we are familiar with the amendment(s) to the Registration
Statement and the final form of Prospectus proposed to be filed, that we are
willing to accept the responsibilities of an underwriter thereunder, and that we
are willing to proceed as therein contemplated. We further confirm that the
statements made under the heading "Underwriting" in such proposed final form of
Prospectus are correct and we authorize you so to advise the Company on our
behalf. We understand that the aforementioned documents are subject to further
change and that we will be supplied with copies of any amendment or amendments
to the Registration Statement and of any amended Prospectus promptly, if and
when received by you, but the making of such changes and amendments shall not
release us or affect our obligations hereunder or under the Underwriting
Agreement.

     16. Indemnification. Each Underwriter, including you, agrees to indemnify
and hold harmless each other Underwriter and each person who controls any other
Underwriter within the meaning of Section 15 of the Securities Act of 1933, as
amended, to the extent of their several commitments under the Underwriting
Agreement and upon the terms that such Underwriter agrees to indemnify and hold
harmless the Company as set forth in Section 7 of the Underwriting Agreement.
The Agreement contained in this Section 16 shall survive any termination of this
Agreement Among Underwriters.

     17. Capital Requirements. We confirm that our ratio of aggregate
indebtedness to net capital is such that we may, in accordance with and pursuant
to Rule 15c3-1, promulgated by the Securities and Exchange Commission under the
Securities Exchange Act of 1934, agree to purchase the number of Securities we
may be obligated to purchase under any provision of the Underwriting Agreement
or this Agreement.

     18. Miscellaneous. We have transmitted herewith a completed Underwriters'
Questionnaire on the form thereof supplied by you. Any notice hereunder from you
to us or from us to you shall be deemed to have been duly give if sent by
registered mail, telegram, teletype, telex, telecopier, graphic scan, or other
written form of telecommunication to us at our address as set forth in the
Underwriting Agreement, or to you at the address set forth on the first page of
this Agreement.

     You hereby confirm that you are registered as a broker-dealer with the
United States Securities and Exchange Commission and that you are a member of

broker-dealer not eligible for membership under Section I of the Bylaws of the
NASD, who agrees to make no sales within the United States, its territories or
possessions, or to persons who are nationals thereof or residents therein, and,
in making sales, to comply with the requirements of the NASD's Interpretation
with Respect to Free Riding and Withholding, and with Sections 2730, 2740 and
2420 to the extent applicable to foreign nonmember brokers or dealers, and
Section 2750 of the NASD's Rules of Fair Practice.

     We will comply with all applicable federal laws, the laws of the states or
other jurisdictions concerned and the Rules and Regulations of the NASD,
including, but not limited to, Section 2740 of the Rules of Fair Practice.

     This instrument may be signed by the Underwriters in various counterparts
which together shall constitute one and the same agreement among all the
Underwriters and shall become effective as between us at such time as you shall
have confirmed same by returning an executed copy to us, and thereafter, as to
us and the other Underwriters, upon execution by them of counterparts which are
confirmed by you. In no event, however, shall we have any liability under this
Agreement if the Underwriting Agreement is not executed.


                                                                               6

                                                                        , 19

Dear Sirs:

enclosed preliminary Prospectus, proposes to offer on a firm commitment basis,
subject to the terms and conditions and execution of the Underwriting Agreement,

Company. The Securities are more particularly described in the enclosed
preliminary Prospectus, additional copies of which will be supplied in
reasonable quantities upon request. Copies of the definitive Prospectus will be
supplied after the effective date of the Registration Statement.
    

   
     2. The Underwriter is soliciting offers to buy, upon the terms and
conditions hereof, a part of the Securities from Selected Dealers, including you
who are to act as principal and who are (i) registered with the Securities and
Exchange Commission ("Commission") as broker-dealers under the Securities
Exchange Act of 1934, as amended ("1934 Act"), and members in good standing with
the National Association of Securities Dealers, Inc. ("NASD"), or (ii) dealers
or institutions with their principal place of business located outside the
United States, its territories and possessions who are not eligible for
membership in the NASD and who agree to make no sales within the United States,
its territories or possessions or to persons who are nationals thereof or
residents therein and, in making sales, to comply with the NASD's Interpretation
with Respect to Free Riding and Withholding and with Sections 2730, 2740, 2420,
to the extent applicable to foreign nonmember brokers or dealers, and Section
2750 of the NASD's Rules of Fair Practice. The Securities are to be offered at a
public price of $      per share of Common Stock. Selected Dealers will be
allowed a concession of not less than $      per share, except as provided
below. You will be notified of the precise amount of such concession prior to
the effective date of the Registration Statement. You may reallow not in excess
of $      per share to dealers who meet the requirements set forth in this
Section 2. This offer is solicited subject to the issuance and delivery of the
Securities and their acceptance by the Underwriter, to the approval of legal
matters by counsel and to the terms and conditions as herein set forth.
    

     3. Your offer to purchase may be revoked in whole or in part without
obligation or commitment of any kind by you and any time prior to acceptance and
no offer may be accepted by us and no sale can be made until after the
registration statement covering the Securities has become effective with the
Commission. Subject to the foregoing, upon execution by you of the Offer to
Purchase below and the return of same to us, you shall be deemed to have offered
to purchase the number of Securities set forth in your offer on the basis set
forth in paragraph 2 above.


                                                                               1


<PAGE>   2
Any oral notice by us of acceptance of your offer shall be immediately followed
by written or telegraphic confirmation preceded or accompanied by a copy of the
Prospectus. If a contractual commitment arises hereunder, all the terms of this
Selected Dealers Agreement shall be applicable. We may also make available to
you an allotment to purchase Securities, but such allotment shall be subject to
modification or termination upon notice from us any time prior to an exchange of
confirmations reflecting completed transactions. All references hereafter in
this Agreement to the purchase and sale of Securities assume and are applicable
only if contractual commitments to purchase are completed in accordance with the
foregoing.

     4. You agree that in reoffering said Securities, if your offer is accepted
after the effective date, you will make a bona fide public distribution of same.
You will advise us upon request of Securities purchased by you remaining unsold
and we shall have the right to repurchase such Securities upon demand at the
public offering price without paying the concession with respect to any
Securities so repurchased. Any of the Securities purchased by you pursuant to
this Agreement are to be subject to the terms hereof. Securities shall not be
offered or sold by you below the public offering price before the termination of
this Agreement.

     5. Payment for Securities which you purchase hereunder shall be made by you
on or before three (3) business days after the date of each confirmation by
certified or bank cashier's check payable to the Underwriter. Certificates for
the Securities shall be delivered as soon as practicable after delivery
instructions are received by the Underwriter.

     6. A registration statement covering the offering has been filed with the
Securities and Exchange Commission in respect to the Securities. You will be
promptly advised when the registration statement becomes effective. Each
Selected Dealer in selling Securities pursuant hereto agrees (which agreement
shall also be for the benefit of the Company) that it will comply with the
applicable requirements of the Securities Act of 1933 and of the Securities
Exchange Act of 1934 and any applicable rules and regulations issued under said
Acts. No person is authorized by the Company or by the Underwriter to give any
information or to make any representations other than those contained in the
Prospectus in connection with the sale of the Securities. Nothing contained
herein shall render the Selected Dealers a member of the Underwriting Group or
partners with the Underwriter or with one another.

     7. You will be informed by us as to the states in which we have been
advised by counsel the Securities have been qualified for sale or are exempt
under the respective securities or blue sky laws of such states, but we have not
assumed and will not assume any obligation or responsibility as to the right of
any Selected Dealer to sell Securities in any state. You agree not to sell
Securities in any other state or jurisdiction and to not sell Securities in any
state or jurisdiction unless you are qualified or licensed to sell securities in
such state or jurisdiction.

     8. The Underwriter shall have full authority to take such action as it may
deem advisable in respect of all matters pertaining to the offering or arising
thereunder. The Underwriter shall not be under any liability to you, except such
as may be incurred under the Securities Act of 1933 and the rules and
regulations thereunder, except for lack of good faith and except for obligations
assumed by us in this Agreement, and no obligation on our part shall be implied
or inferred herefrom.

     9. Selected Dealers will be governed by the conditions herein set forth
until this Agreement is terminated. This Agreement will terminate when the
offering is completed. Nothing herein contained shall be deemed a commitment on
our part to sell you any Securities; such contractual commitment can only be
made in accordance with the provisions of paragraph 3 hereof.

   
     10. You represent that you are a member in good standing of the NASD and
registered as a broker-dealer with the Commission, or that you are a foreign
broker-dealer not eligible for membership under Section 1 of the Bylaws of the
NASD who agrees to make no sales within the United States, its territories or
possessions or to persons who are nationals thereof or residents therein and, in
making sales, to comply with the NASD's interpretation with Respect to
Free Riding and Withholding and with Sections 2730, 2740, 2420 to the extent
applicable to foreign nonmember brokers and dealers, and Section 2750 of the
NASD's Rules of Fair Practice. Your attention is called to and you agree to
comply with the following: (a) Article III, Section 1 of the Rules of Fair
Practice of the NASD and the interpretations of said Section promulgated by the
Board of Governors of the NASD including Section 24 and the 
    


                                                                               2


<PAGE>   3
interpretation with respect to "Free-Riding and Withholding;" (b) Section 10(b)
of the 1934 Act and Regulation M and Rule 10b-10 of the general rules and
regulations promulgated under the 1934 Act; and (c) Rule 15c2-8 of the general
rules and regulations promulgated under the 1934 Act requiring the distribution
of a preliminary Prospectus to all persons reasonably expected to be purchasers
of the Securities from you at least 48 hours prior to the time you expect to
mail confirmations. You, as a member of the NASD, by signing this Agreement,
acknowledge that you are familiar with the cited laws and rules and agree that
you will not directly and/or indirectly violate any provisions of applicable law
in connection with your participation in the distribution of the Securities.

     11. In addition to compliance with the provisions of paragraph 10 hereof,
you will not, until advised by us in writing or by wire that the entire offering
has been distributed and closed, bid for or purchase Securities in the open
market or otherwise make a market in the Securities or otherwise attempt to
induce others to purchase the Securities in the open market. Nothing contained
in this paragraph 11 shall, however, preclude you from acting as agent in the
execution of unsolicited orders of customers in transactions effectuated for
them through a market maker.

     12. You understand that the Underwriter may in connection with the offering
engage in stabilizing transactions. If the Underwriter contracts for or
purchases in the open market in connection with such stabilization any
Securities sold to you hereunder and not effectively placed by you, the
Underwriter may charge you the Selected Dealer's concession originally allowed
you on the Securities so purchased and you agree to pay such amount to us on
demand.

     13. By submitting an Offer to Purchase you confirm that you may, in
accordance with Rule 15c3-1 adopted under the 1934 Act, agree to purchase the
number of Securities you may become obligated to purchase under the provisions
of this Agreement.

     14. All communications from you should be directed to us at 495 Post Road
East, Westport, CT 06880 Attn: Daniel T. Guilfoile, Director Investment Banking
Division (203-226-1857) and fax (203-226-5343). All communications from us to

                          MEDICAL SCIENCE SYSTEMS, INC.

                                 UNDERWRITERS'
                               WARRANT TO PURCHASE
                             SHARES OF COMMON STOCK

   
     This is to Certify That, FOR VALUE RECEIVED, ____________________________
(the "Holder") is entitled to purchase, subject to the provisions of this
warrant (the "Warrant"), from Medical Science Systems, Inc. (the "Company"), a
Texas corporation, at any time on or after        , 1998, and not later than
3:30 p.m., Eastern Time, on 2002,        shares of Common Stock of the Company
("Securities") exercisable at a purchase price for the shares of Common Stock
which is 165% of the public offering price of the Common Stock ($        ). The
number of Securities to be received upon the exercise of this Warrant and the
price to be paid for the Securities may be adjusted from time to time as
hereinafter set forth. The purchase price of a share of Common Stock in effect
at any time and as adjusted from time to time is hereinafter sometimes referred
to as the "Exercise Price." This Warrant is or may be one of a series of
Warrants identical in form issued by the Company to purchase an aggregate of
250,000 shares of Common Stock. The shares of Common Stock, as adjusted from
time to time underlying the Warrants are hereinafter sometimes referred to as
"Warrant Shares". The Common Stock issuable upon the exercise hereof are in all
respects identical to the Common Stock being purchased by the Underwriter for
resale to the public pursuant to the terms and conditions of the Underwriting
Agreement.
    

   
     (a) Exercise of Warrant. Subject to the provisions of Section (g) hereof,
this Warrant may be exercised in whole or in part at anytime or from time to
time on or after         , 1998, but not later than 3:30 p.m., Eastern Time on ,
2002, or if           , 2002, is a day on which banking institutions are
authorized by law to close, then on the next succeeding day which shall not be
such a day, by presentation and surrender hereof to the Company or at the office
of its stock transfer agent, if any, with the Purchase Form annexed hereto duly
executed and accompanied by payment of the Exercise Price for the number of
shares specified in such Form, together with all federal and state taxes
applicable upon such exercise. The Company agrees to provide notice to the
Holder that any tender offer is being made for the Company's shares of Common
Stock no later than the day the Company becomes aware that any tender offer is
being made for the Company's shares of Common Stock. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for
cancellation, execute and deliver a new Warrant evidencing the right of the
Holder to purchase the balance of the shares purchasable hereunder along with
any additional Underwriters' Warrants not exercised. Upon receipt by the Company
of this Warrant at the office of the Company or at the office of the Company's
stock transfer agent, in proper form for exercise and accompanied by the total
Exercise Price, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of the Company shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
the Holder.
    

     (b) Reservation of Securities. The Company hereby agrees that at all times
there shall be reserved for issuance and/or delivery upon exercise of this
Warrant such number of shares of its Common Stock as shall be required for
issuance or delivery upon exercise of this Warrant. The Company covenants and
agrees that, upon exercise of the


                                                                               1
<PAGE>   2

   
Warrants and payment of the Exercise Price therefor, all shares of Common Stock
and other securities issuable upon such exercise shall be duly and validly
issued, fully paid, non-assessable and not subject to the preemptive rights of
any stockholder. As long as the Warrants shall be outstanding, the Company shall
use its best efforts to cause all shares of Common Stock issuable upon the
exercise of the Warrants to be listed (subject to official notice of issuance)
on all securities exchanges on which the Common Stock issued to the public in
connection herewith may then be listed and/or quoted on NASDAQ.
    

     (c) Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant. With
respect to any fraction of a share called for upon any exercise hereof, the
Company shall pay to the Holder an amount in cash equal to such fraction
multiplied by the current market value of such fractional share, determined as
follows:

     (1) If the Common Stock is listed on a national securities exchange or
admitted to unlisted trading privileges on such exchange, the current value
shall be the last reported sale price of the Common Stock on such exchange on
the last business day prior to the date of exercise of this Warrant or if no
such sale is made on such day, the average of the closing bid and asked prices
for such day on such exchange; or

   
     (2) If the Common Stock is not so listed or admitted to unlisted trading
privileges, the current value shall be the mean of the last reported bid and
asked prices reported by the National Association of Securities Dealers
Automated Quotation System (or, if not so quoted on NASDAQ, by the National
Quotation Bureau, Inc.) on the last business day prior to the date of the
exercise of this Warrant; or
    

     (3) If the Common Stock is not so listed or admitted to unlisted trading
privileges and bid and asked prices are not so reported, the current value shall
be an amount, not less than book value, determined in such reasonable manner as
may be prescribed by the Board of Directors of the Company, such determination
to be final and binding on the Holder.

   
     (d) Exchange, Assignment or Loss of Warrant. This Warrant is exchangeable,
without expense, at the option of the Holder, upon presentation and surrender
hereof to the Company or at the office of its stock transfer agent, if any, for
other Warrants of different denominations entitling the Holder thereof to
purchase (under the same terms and conditions as provided by this Warrant) in
the aggregate the same number of shares of Common Stock purchasable hereunder.
This Warrant may not be sold, transferred, assigned, or hypothecated until after
one year from the effective date of the registration statement except that it
may be (i) assigned in whole or in part to the officers of the "Underwriter",
and (ii) transferred to any successor to the business of the "Underwriter." Any
such assignment shall be made by surrender of this Warrant to the Company, or at
the office of its stock transfer agent, if any, with the Assignment Form annexed
hereto duly executed and with funds sufficient to pay any transfer tax;
whereupon the Company shall, without charge, execute and deliver a new Warrant
in the name of the assignee named in-such instrument of assignment, and this
Warrant shall promptly be canceled. This Warrant may be divided or combined with
other Warrants which carry the same rights upon presentation hereof at the
office of the Company or at the office of its stock transfer agent, if any,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any Warrants issued in substitution for or
replacement of this Warrant, or into which this Warrant may be divided or
exchanged. Upon receipt by the Company of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender and cancellation of this Warrant, if mutilated, the Company will
execute and deliver a new Warrant of like tenor and date. Any such new Warrant
executed and delivered shall constitute an additional contractual obligation on
the part of the Company, whether or not this Warrant so lost, stolen, destroyed,
or mutilated shall be at any time enforceable by anyone.
    

     (e) Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.


                                                                               2


<PAGE>   3
     (f) Notices to Warrant Holders. So long as this Warrant shall be
outstanding and unexercised (i) if the Company shall make any stock distribution
upon the Common Stock, or (ii) if the Company shall offer to the holders of
Common Stock for subscription or purchase by them any shares of stock of any
class or any other rights, or (iii) if any capital reorganization of the
Company, reclassification of the capital stock of the Company, consolidation or
merger of the Company with or into another corporation, sale, lease or transfer
of all or substantially all of the property and assets of the Company to another
corporation, or voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be effected, then, in any such case, the Company shall
cause to be delivered to the Holder, at least ten (10) days prior to the date
specified in (x) or (y) below, as the case may be, a notice containing a brief
description of the proposed action and stating the date on which (x) a record is
to be taken for the purpose of such dividend, distribution or rights, or (y)
such reclassification, reorganization, consolidation, merger, conveyance, lease,
dissolution, liquidation or winding up is to take place and the date, if any, is
to be fixed, as of which the holders of Common Stock of record shall be entitled
to exchange their shares of Common Stock for equivalent securities or other
property deliverable upon such reclassification, reorganization, consolidation,
merger, conveyance, dissolution, liquidation or winding up.

     (g) Adjustment of Exercise Price and Number of Shares of Common Stock
Deliverable.

   
     (A)(i) Except as hereinafter provided, in the event the Company shall, at
any time or from time to time after the date hereof, issue any shares of Common
Stock as a stock dividend to the holders of Common Stock, or subdivide or
combine the outstanding shares of Common Stock into a greater or lesser number
of shares (any such issuance, subdivision or combination being herein called a
"Change of Shares"), then, and thereafter upon each further Change of Shares,
the Exercise Price for the Warrants (whether or not the same shall be issued and
outstanding) in effect immediately prior to such Change of Shares shall be
changed to a price (including any applicable fraction of a cent to the nearest
cent) determined by dividing (i) the sum of (a) the total number of shares of
Common Stock outstanding immediately prior to such Change of Shares, multiplied
by the Exercise Price in effect immediately prior to such Change of Shares, and
(b) the consideration, if any, received by the Company upon such issuance,
subdivision or combination by (ii) the total number of shares of Common Stock
outstanding immediately after such Change of Shares; provided, however, that in
no event shall the Exercise Price be adjusted pursuant to this computation to an
amount in excess of the Exercise Price in effect immediately prior to such
computation, except in the case of a combination of outstanding shares of Common
Stock.
    

     For the purposes of any adjustment to be made in accordance with this
Section (g) the following provisions shall be applicable:

          (I) Shares of Common Stock issuable by way of dividend or other
     distribution on any capital stock of the Company shall be deemed to have
     been issued immediately after the opening of business on the day following
     the record date for the determination of shareholders entitled to receive
     such dividend or other distribution and shall be deemed to have been issued
     without consideration.

          (II) The number of shares of Common Stock at any one time outstanding
     shall not be deemed to include the number of shares issuable (subject to
     readjustment upon the actual issuance thereof) upon the exercise of
     options, rights or warrants and upon the conversion or exchange of
     convertible or exchangeable securities.

     (ii) Upon each adjustment of the Exercise Price pursuant to this Section
(g), the number of shares of Common Stock purchasable upon the exercise of each
Warrant shall be the number derived by multiplying the number of shares of
Common Stock purchasable immediately prior to such adjustment by the Exercise
Price in effect prior to such adjustment and dividing the product so obtained by
the applicable adjusted Exercise Price.

     (B) In case of any reclassification or change of outstanding shares of
Common Stock issuable upon exercise of the Warrants (other than a change in par
value, or from par value to no par value, or from no par value to par value or
as a result of a subdivision or combination), or in case of any consolidation or
merger of the Company with or into another corporation other than a merger with
a "Subsidiary" (which shall mean any corporation or corporations, as the 


                                                                               3


<PAGE>   4

case may be, of which capital stock having ordinary power to elect a majority of
the Board of Directors of such corporation (regardless of whether or not at the
time capital stock of any other class or classes of such corporation shall have
or may have voting power by reason of the happening of any contingency) is at
the time directly or indirectly owned by the Company or by one or more
Subsidiaries) or by the Company and one or more Subsidiaries in which merger the
Company is the continuing corporation and which does not result in any
reclassification or change of the then outstanding shares of Common Stock or
other capital stock issuable upon exercise of the Warrants (other than a change
in par value, or from par value to no par value, or from no par value to par
value or as a result of subdivision or combination) or in case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, then, as a condition of such reclassification,
change, consolidation, merger, sale or conveyance, the Company, or such
successor or purchasing corporation, as the case may be, shall make lawful and
adequate provision whereby the Holder of each Warrant then outstanding shall
have the right thereafter to receive on exercise of such Warrant the kind and
amount of securities and property receivable upon such reclassification, change,
consolidation, merger, sale or conveyance by a holder of the number of
securities issuable upon exercise of such Warrant immediately prior to such
reclassification, change, consolidation, merger, sale or conveyance and shall
forthwith file at the principal office of the Company a statement signed by its
President or a Vice President and by its Treasurer or an Assistant Treasurer or
its Secretary or an Assistant Secretary evidencing such provision. Such
provisions shall include provision for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in Section
(g)(A). The above provisions of this Section (g)(B) shall similarly apply to
successive reclassifications and changes of shares of Common Stock and to
successive consolidations, mergers, sales or conveyances.

   
     (C) Irrespective of any adjustments or changes in the Exercise Price or
the number of shares of Common Stock purchasable upon exercise of the Warrants,
the Warrant Certificates theretofore and thereafter issued shall, unless the
Company shall exercise its option to issue new Warrant Certificates pursuant
hereto, continue to express the Exercise Price per share and the number of
shares purchasable thereunder as the Exercise Price per share and the number of
shares purchasable thereunder as expressed in the Warrant Certificates when the
same were originally issued.
    

   
     (D) After each adjustment of the Exercise Price pursuant to this Section
(g), the Company will promptly prepare a certificate signed by the Chairman or
President, and by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary, of the Company setting forth: (i) the Exercise Price as so
adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of
each Warrant, after such adjustment, and (iii) a brief statement of the facts
accounting for such adjustment. The Company will promptly file such certificate
in the Company's minute books and cause a brief summary thereof to be sent by
ordinary first class mail to each Holder at his last address as it shall appear
on the registry books of the Company. No failure to mail such notice nor any
defect therein or in the mailing thereof shall affect the validity thereof
except as to the holder to whom the Company failed to mail such notice, or
except as to the holder whose notice was defective. The affidavit of an officer
or the Secretary or an Assistant Secretary of the Company that such notice has
been mailed shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.
    

     (E) No adjustment of the Exercise Price shall be made as a result of or in
connection with the issuance or sale of shares of Common Stock if the amount of
said adjustment shall be less than $.10, provided, however, that in such case,
any adjustment that would otherwise be required then to be made shall be carried
forward and shall be made at the time of and together with the next subsequent
adjustment that shall amount, together with any adjustment so carried forward,
to at least $.10. In addition, Holders shall not be entitled to cash dividends
paid by the Company prior to the exercise of any Warrant or Warrants held by
them.

     (F) In the event that the Company shall at any time prior to the exercise
of all Warrants declare a dividend consisting solely of shares of Common Stock
or otherwise distribute to its stockholders any assets, property, rights,
evidences of indebtedness, the Holders of the unexercised Warrants shall
thereafter be entitled, in addition to the shares of Common Stock or other
securities and property receivable upon the exercise thereof, to receive, upon
the exercise of such Warrants, the same property, assets, rights, evidences of
indebtedness, that they would have been


                                                                               4

entitled to receive at the time of such dividend or distribution as if the
Warrants had been exercised immediately prior to such dividend or distribution.
At the time of any such dividend or distribution, the Company shall make
appropriate reserves to ensure the timely performance of the provisions of this
Section (g).

   
     (h) Piggyback Registration. If, at any time commencing one year from the
date hereof and expiring six (6) years thereafter, the Company proposes to
register any of its securities under the Securities Act of 1933, as amended (the
"Act") (other than in connection with a merger or pursuant to Form S-8, S-4 or
other comparable registration statement) it will give written notice by
registered mail, at least thirty (30) days prior to the filing of each such
registration statement, to the Underwriter and to all other Holders of the
Warrants and/or the Warrant Stock of its intention to do so. If the Underwriter
or other Holders of the Warrants and/or Warrant Stock notify the Company within
twenty (20) days after receipt of any such notice of its or their desire to
include any such securities in such proposed registration statement, the Company
shall afford each of the Underwriters and such Holders of the Warrants and/or
Warrant Stock the opportunity to have any such Warrant Stock registered under
such registration statement.
    

     Notwithstanding the provisions of this Section, the Company shall have the
right at any time after it shall have given written notice pursuant to this
Section (irrespective of whether a written request for inclusion of any such
securities shall have been made) to elect not to file any such proposed
registration statement, or to withdraw the same after the filing but prior to
the effective date thereof.

     (i) Demand Registration.

   
     (1) At any time commencing one year from the date hereof and expiring four
(4) years thereafter, the Holders of the Underwriters' Warrants and/or Warrant
Shares representing a "Majority" (as hereinafter defined) of such securities
(assuming the exercise of all of the Underwriters' Warrants) shall have the
right (which right is in addition to the registration rights under Section (i)
hereof), exercisable by written notice to the Company, to have the Company
prepare and file with the Securities and Exchange Commission (the "Commission"),
on one occasion, a registration statement and such other documents, including a
prospectus, as may be necessary in the opinion of both counsel for the Company
and counsel for the Underwriter and Holders, in order to comply with the
provisions of the Act, so as to permit a public offering and sale of their
respective Warrant Shares for nine (9) consecutive months by such Holders and
any other holders of the Underwriters' Warrants and/or Warrant Shares who notify
the Company within ten (10) days after receiving notice from the Company of such
request.
    

   
     (2) The Company covenants and agrees to give written notice of any
registration request under this Section (i) by any Holder or Holders to all
other registered Holders of the Underwriters' Warrants and the Warrant Shares
within ten (10) days from the date of the receipt of any such registration
request.
    

   
     (3) In addition to the registration rights under this Section (i) at any
time commencing one year after the date hereof and expiring four (4) years
thereafter, the Holders of Underwriters' Warrants and/or Warrant Shares shall
have the right, exercisable by written request to the Company, to have the
Company prepare and file, on one occasion, with the Commission a registration
statement so as to permit a public offering and sale for nine (9) consecutive
months by such Holders of its Warrant Shares; provided, however, that the
provisions of Section (i)(2) hereof shall not apply to any such registration
request and registration and all costs incident thereto shall be at the expense
of the Holder or Holders making such request.
    

   
     (4) The Company shall include such Underwriters' Warrants in the
Registration Statement relating to this offering and shall keep such
Registration Statement current at least until the expiration of such
Underwriters' Warrants or shall bear all of the costs of a new registration
statement in the event the Underwriters' Warrants are to be exercised.
    

     (j) Covenants of the Company With Respect to Registration. In connection
with any registration under Section (h) or (i) hereof, the Company covenants and
agrees as follows:


                                                                               5


<PAGE>   6

   
     (i) The Company shall use its best efforts to file a registration statement
within sixty (60) days of receipt of any demand therefor, shall use its best
efforts to have any registration statement declared effective at the earliest
possible time, and shall furnish each Holder desiring to sell Warrant Shares
such number of prospectuses as shall reasonably be requested.
    

   
     (ii) The Company shall pay all costs (excluding fees and expenses of
Holder(s)' counsel and any underwriting or selling commissions), fees and
expenses in connection with all registration statements filed pursuant to
Sections (h), (i) and (o) hereof including, without limitation, the Company's
legal and accounting fees, printing expenses, blue sky fees and expenses. If the
Company shall fail to comply with the provisions of Section (j)(i), the Company
shall, in addition to any other equitable or other relief available to the
Holder(s), extend the Exercise Period by such number of days as shall equal the
delay caused by the Company's failure.
    

   
     (iii) The Company will take all necessary action which may be required in
qualifying or registering the Warrant Shares included in a registration
statement for offering and sale under the securities or blue sky laws of such
states as reasonably are requested by the Holder(s), provided that the Company
shall not be obligated to execute or file any general consent to service of
process or to qualify as a foreign corporation to do business under the laws of
any such jurisdiction.
    

   
     (iv) The Company shall indemnify the Holder(s) of the Warrant Shares to be
sold pursuant to any registration statement and each person, if any, who
controls such Holders within the meaning of Section 15 of the Act or Section
20(a) of the Securities Exchange Act of 1934, as amended ("Exchange Act"), from
and against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify the Underwriter contained in Section 7 of the
Underwriting Agreement.
    

   
     (v) The Holder(s) of the Warrant Shares to be sold pursuant to a
registration statement, and their successors and assigns, shall severally, and
not jointly, indemnify the Company, its officers and directors and each person,
if any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information
furnished by or on behalf of such Holders, or their successors or assigns, for
specific inclusion in such registration statement to the same extent with the
same effect as the provisions contained in Section 7 of the Underwriting
Agreement pursuant to which the Underwriter has agreed to indemnify the Company.
    

     (vi) The Holder(s) shall exercise their Warrants prior to the initial
filing of any registration statement or the effectiveness thereof.

   
     (vii) The Company shall not permit the inclusion of any securities other
than the Warrant Shares to be included in any registration statement filed
pursuant to Section (i) hereof, or permit any other registration statement to be
or remain effective during the effectiveness of a registration statement filed
pursuant to Section (i) hereof, other than a secondary offering of equity
securities by the Company, without the prior written consent of the Holders of
the Warrants and Warrant Shares representing a Majority (as herein defined) 
of such securities (assuming an exercise of all the Warrants).
    

   
     (viii) The Company shall furnish to each Holder participating in the
offering and to each Underwriter, if any, a signed counterpart, addressed to
such Holder or Underwriter, of (x) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (y) a "cold comfort" letter dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting agreement) signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement,
    


                                                                               6


<PAGE>   7

   
in each case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to Underwriters in underwritten public
offerings of securities.
    

     (ix) The Company shall as soon as practicable after the effective date of
the registration statement, and in any event within 15 months thereafter, make
"generally available to its security holders" (within the meaning of Rule 158
under the Act) an earnings statement (which need not be audited) complying with
Section 11(a) of the Act and covering a period of at least 12 consecutive months
beginning after the effective date of the registration statement.

   
     (x) The Company shall deliver promptly to each Holder participating in the
offering requesting the correspondence and memoranda described below and to the
managing underwriters, copies of all correspondence between the Commission and
the Company, its counsel or auditors and all memoranda relating to discussions
with the Commission or its staff with respect to the registration statement and
permit each Holder and Underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the
registration statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD"). Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at
such reasonable times and as often as any such Holder or Underwriter shall
reasonably request.
    

   
     (xi) The Company shall enter into an underwriting agreement with the
managing underwriters, which may be the Underwriter. Such agreement shall be
satisfactory in form and substance to the Company, and such managing
underwriters, and shall contain such representations, warranties and covenants
by the Company and such other terms as are customarily contained in agreements
of that type used by the managing underwriter; provided however, that no Holder
shall be required to make any representations, warranties or covenants or grant
any indemnity to which it shall object in any such underwriting agreement. The
Holders shall be parties to any underwriting agreement relating to an
underwritten sale of their Warrant Securities and may, at their option, require
that any or all the representations, warranties and covenants of the Company to
or for the benefit of such Underwriters shall also be made to and for the
benefit of such Holders. Such Holders shall not be required to make any
representations or warranties to or agreements with the Company or the
Underwriters except as they may relate to such Holders and their intended
methods of distribution.
    

   
     (xii) For purposes of this Agreement, the term "Majority" in reference to
the Holders of Warrants or Warrant Stock, shall mean in excess of fifty (50%) of
the then outstanding Warrants or Warrant Shares that (i) are not held by the
Company, an affiliate, officer, creditor, employee or agent thereof or any of
their respective affiliates, members of their family, persons acting as nominees
or in conjunction therewith or (ii) have not been resold to the public pursuant
to a registration statement filed with the Commission under the Act.
    

     (k) The Company's obligation under Section 6) hereof shall be conditioned
as to each such public offering, upon a timely receipt by the Company in writing
of:

   
          (A) Information as to the terms of such public offering furnished by
     or on behalf of the Holders making a public distribution of their Warrant
     Shares; and
    

   
          (B) Such other information as the Company may reasonably require from
     such Holder, or any Underwriter for any of them, for inclusion in such
     registration statement or offering statement or post-effective amendment.
    

   
          (C) An agreement by the Holder to sell his Warrants and Warrant
     Shares on the basis provided in the Underwriting Agreement.
    

   
     (l) The Company's agreements with respect to the Warrant Shares in this
Warrant will continue in effect regardless of the exercise or surrender of this
Warrant.
    


                                                                               7



<PAGE>   8
   
     (m) Any notices or certificates by the Company to the Holder and by the
Holder to the Company shall be deemed delivered if in writing and delivered
personally or sent by certified mail, to the Holder, addressed to him or sent to
Nutmeg Securities, Ltd., 495 Post Road East, Westport, CT 06880, or, if the
Holder has designated, by notice in writing to the Company, any other address,
to such other address, and, if to the Company, addressed to it at 4400 MacArthur
Boulevard, Suite 980, Newport Beach, CA 92660. The Company may change its
address by written notice to Nutmeg Securities, Ltd.
    

   
     (n) Limited Transferability. This Warrant Certificate and the Warrant may
not be sold, transferred, assigned or hypothecated for a one-year period after
the effective date of the Registration Statement except to Underwriters of the
Offering referred to in the Underwriting Agreement or to individuals who are
either partners or officers of such an Underwriter or by operation of law. The
Warrant may be divided or combined, upon request to the Company by the Holder,
into a certificate or certificates evidencing the same aggregate number of
Warrants. The Warrant may not be offered, sold, transferred, pledged or
hypothecated in the absence of any effective registration statement as to such
Warrant filed under the Act, or an exemption from the requirement of such
registration, and compliance with the applicable state securities laws. The
Company may require an opinion of counsel satisfactory to the Company that such
registration is not required and that such laws are complied with. The Company
may treat the registered holder of this Warrant as he or it appears on the
Company's book at any time as the Holder for all purposes. The Company shall
permit the Holder or his duly authorized attorney, upon written request during
ordinary business hours, to inspect and copy or make extracts from its books
showing the registered holders of Warrants. 
    

   
     (o) Transfer to Comply With the Securities Act of 1933. The Company may
cause the following legend, or one similar thereto, to be set forth on the
Warrants and on each certificate representing Warrant Shares, or any other
security issued or issuable upon exercise of this Warrant not theretofore
distributed to the public or sold to Underwriters for distribution to the public
pursuant to Sections (h) or (i) hereof; unless counsel satisfactory to the
Company is of the opinion as to any such certificate that such legend, or one
similar thereto, is unnecessary:
    

   
     "The warrants represented by this certificate may not be offered for sale,
     sold or otherwise transferred except pursuant to an opinion of counsel
     satisfactory to the Company is obtained stating that such offer or sale is
     in compliance with state and federal securities law."
    

     (p) Applicable Law. This Warrant shall be governed by, and construed in
accordance with, the laws of the State of Connecticut , without giving effect to
conflict of law principles.

     (q) This Warrant may not be extended except in a writing signed by each
Holder and the Company.

   
     (r) The indemnification provisions of this Warrant shall survive until 
the earlier of (i) one (1) year from the date of exercise; or (ii)           ,
2002 (the date after which this Warrant may not be exercised).
    

                                                                               8

                    Re:  Registration Statement on Form SB-2

Gentlemen:

        We have acted as counsel to Medical Science Systems, Inc. (the
"Company"), a Texas corporation, in connection with the Registration Statement
on Form SB-2 (333-37441), filed with the Securities and Exchange Commission on
October 8, 1997, as amended (the "Registration Statement"), covering 2,500,000
shares of the Company's no par value Common Stock (the "Shares").

        In acting as counsel for the Company and arriving at the opinions as
expressed below, we have examined and relied upon originals or copies, certified
or otherwise identified to our satisfaction, of such records of the Company,
agreements and other instruments, certificates of officers and representatives
of the Company, certificates of public officials and other documents as we have
deemed necessary or appropriate as a basis for the opinions expressed herein.

        In connection with our examination we have assumed the genuineness of
all signatures, the authenticity of all documents tendered to us as originals,
the legal capacity of natural persons and the conformity to original documents
of all documents submitted to us as certified or photostated copies.

        Based on the foregoing, and subject to the qualifications and
limitations set forth herein, it is our opinion that the Shares have been duly
authorized and when issued, delivered and paid for, will be validly issued,
fully paid and non-assessable.

        We express no opinion with respect to laws other than those of the State
of California and federal laws of the United States of America, and we assume no
responsibility as to the applicability thereof, or the effect thereon, of the
laws of any other jurisdiction.

       We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to its use as part of the Registration Statement.

                                          Very truly yours,


                                          /s/ JEFFERS, WILSON, SHAFF & FALK, LLP
