ITEM 1. BUSINESS

     Integ Incorporated ("Integ" or the "Company") is developing the LifeGuide
System, a next generation hand-held glucose monitoring product for use by people
with diabetes that avoids the pain and blood associated with conventional
"finger-stick" technologies. Utilizing the Company's proprietary interstitial
fluid ("ISF") sampling technology, the LifeGuide System will allow people with
diabetes to frequently self-monitor their glucose levels without repeatedly
enduring the pain of lancing their fingers to obtain a blood sample. The Company
believes that the LifeGuide System represents a significant technological
advance in glucose monitoring and will enable people with diabetes to manage
their disease more effectively and conveniently. The Company anticipates that it
will file a 510(k) premarket notification with the United States Food and Drug
Administration (the "FDA") for the LifeGuide System in the fourth quarter of
1997.

     Integ, a Minnesota corporation, was incorporated in April 1990.

INDUSTRY OVERVIEW

     It is estimated that there are as many as 100 million people with diabetes
worldwide. Diabetes is a chronic disease affecting overall health which can lead
to severe complications and requires active disease management on a daily basis.

     The use of personal glucose monitors is a key factor in the management of
diabetes. Glucose levels are dynamic and vary throughout the day depending upon
food intake, insulin availability, exercise, stress and illness. People with
diabetes attempt to maintain their glucose levels within an acceptable range
through the use of insulin injections, oral hypoglycemic (glucose reducing)
agents, diet, exercise or a combination of these activities. People with
diabetes test their glucose levels at multiple times during the day, including
before eating or when their glucose levels are suspected to be rising or falling
faster than desired.

                                      -2-
<PAGE>
 
     The Company believes that sales of personal blood glucose monitoring
products have increased significantly in recent years due to technological
innovations, the development of retail distribution channels and increasing
awareness of the benefits of frequent glucose monitoring. Historically,
consumers have selected devices that offer the greatest ease of use while
providing fast and accurate blood glucose measurements, and technological
innovators have tended to capture significant market share rapidly.

     Due to the release in 1993 of the results of the landmark Diabetes Control
and Complications Trial (the "DCCT"), people with diabetes are becoming
increasingly aware of the need for more intensive glucose monitoring. The
purpose of the trial, which studied more than 1,400 people with Type I (insulin-
dependent or juvenile onset) diabetes over a nine-year period, was to determine
whether tighter control over glucose levels would prevent the onset or slow the
progression of the serious complications that often accompany diabetes.
Participants in the DCCT were randomly assigned to either intensive or
conventional therapy groups. Conventional therapy consisted of testing glucose
levels once or twice a day with one or two daily insulin injections. Intensive
therapy involved testing glucose levels at least four times a day with at least
three insulin injections and appropriate modifications to diet and exercise and
insulin doses in accordance with the measured glucose levels. The DCCT
demonstrated that more intensive treatment of Type I diabetes can reduce the
risk of developing various diabetes-related complications by approximately 60%.

     The DCCT panel has recommended that people with Type I diabetes follow an
intensive therapy program, including testing their glucose levels at least four
times a day. Many experts on diabetes also believe that people with Type II 
(non-insulin-dependent or adult onset) diabetes, who do not typically check
their glucose levels at regular intervals, would also benefit from regular
monitoring. Currently, however, the majority of people with diabetes who use
insulin monitor their glucose levels less than once per day.

EXISTING PERSONAL BLOOD GLUCOSE MONITORING SYSTEMS AND NEW ALTERNATIVE
TECHNOLOGIES

     Commercially available glucose monitoring systems involve obtaining a
patient's blood sample in order to measure glucose. The primary drawbacks to
this approach are the pain associated with lancing a fingertip to produce the
sample and the mess and inconvenience of handling blood. In conventional glucose
monitoring systems, blood samples are taken from the fingertips because of the
high concentration of capillaries at that site and because the blood produced at
the fingertip can most easily be applied directly to the test strips used in
such devices. Since nerve endings are concentrated in the fingertips, however,
this sampling process results in a significant degree of pain. The level of
patient discomfort is compounded because the fingertips offer a limited surface
area from which to obtain a blood sample, requiring the patient to repeatedly
sample from the same site. In addition, many people with diabetes are
uncomfortable with routinely testing glucose levels in the presence of others
because of the negative perceptions associated with visible blood.

     Most currently available personal blood glucose monitoring systems employ a
disposable test strip in conjunction with a battery-powered, hand-held meter.
These systems usually require the user to (1) assemble the finger-lancing
device, (2) determine the calibration code from the test strip package and
adjust the meter as required to be properly calibrated to the test strip being
used, (3) insert the test strip into the meter, (4) lance the finger and wait
for a drop of blood to form on the fingertip, and (5) apply the blood sample to
the test strip and wait for the meter to display the results.

     The goal of most recent glucose monitoring research has been to develop an
accurate system to monitor glucose without the pain of a finger lance or the
need to handle blood. The Company believes that most of the current research and
development in this area involves non-invasive near-infrared spectroscopic,
reverse iontophoretic, or ISF technologies.

     Non-invasive near-infrared spectroscopic technology generally attempts to
estimate glucose levels by measuring light absorption when an infrared light
signal is transmitted through or reflected off of a body part. Due to several
technical demands, this approach requires the use of the near-infrared waveband
region for measurement of glucose levels. However, this waveband region is only

                                      -3-
<PAGE>
 
weakly absorbed by glucose, resulting in low signal to noise ratios that make
signal detection difficult.  In addition, passage of the near-infrared light
through a structurally complicated medium (such as a fingertip) produces complex
data requiring highly sophisticated algorithms for interpretation.   Development
of these algorithms has proven to be a major technical challenge to the
development of non-invasive near-infrared spectroscopic technologies.

     Reverse iontophoretic technology uses electrical current to draw glucose
molecules out of the skin for measurement. However, this technology has inherent
difficulties relating to the non-physiologic nature of the sample obtained. This
sample has a concentration of glucose much lower than that found in the body,
making the accurate and precise analysis of the sample difficult. In addition, a
reverse iontophoretic device may be required to be worn continuously (creating
the need for frequent calibration), may cause skin irritation due to the long-
term effects of electrical current passage through the skin and, because of the
long sampling times involved, may lead to results that are not clinically
useful.

     ISF technology involves obtaining a sample of ISF from the skin.  ISF
technology is the approach being pursued by Integ and others.  Illustrative of
other ISF approaches, which are different than the Company's unique approach
described below, would be creating an opening in the skin using a laser or other
means, and pulling ISF through the opening and measuring the glucose in the ISF
sample using traditional electro-chemical means.

     No glucose monitor using non-invasive near-infrared spectroscopic, reverse
iontophoretic technologies, ISF technology or any other non-blood based or non-
invasive glucose monitoring technology has ever been commercialized.

     The Company believes that the pain and inconvenience associated with
conventional "finger-stick" blood glucose monitoring systems is the primary
reason that most people with diabetes fail to comply with the recommendations of
the DCCT panel. To date, however, completely non-invasive technologies have
failed to provide a practical alternative to commercially available blood
glucose monitoring systems.

THE INTEG SOLUTION

     The Company is developing the LifeGuide System, utilizing the Company's
proprietary ISF sampling technology, to allow people with diabetes to easily and
accurately measure their glucose levels without the pain of a finger lance or
the need to handle blood. The LifeGuide System captures an extremely small
physiological (as it exists in the body) sample of ISF and then measures the
glucose level in that sample in a compact, easy-to-use device.

     THE INTEG TECHNOLOGY

     The Company's proposed LifeGuide System is based on Company research
indicating that ISF glucose levels correlate closely with blood glucose levels.
ISF is an extracellular fluid that is prevalent throughout the body and the
skin.  ISF is the means through which proteins and chemicals, including glucose,
pass between capillaries and cells.  Since the LifeGuide System's approach
obtains a sample from the outermost layers of the skin almost anywhere on the
body, it will avoid the areas of high nerve density and capillaries found in the
deeper layers of the skin, thus eliminating the pain and blood associated with
conventional "finger-stick" sampling approaches.

     The Company's proprietary method for ISF sampling involves a simple
procedure that draws an ISF sample from the outermost layers of the skin and
captures that sample for measurement.  The ISF sample (approximately 1/50th of a
drop) is analyzed for glucose levels by the LifeGuide Meter utilizing a signal
from the far-infrared waveband region.  The proposed LifeGuide System will
utilize well-established spectroscopic techniques which the Company is
developing into a compact, hand-held, battery-operated configuration.  The
proposed LifeGuide Meter will contain an infrared source set opposite to an
infrared detector, with the sample window on the LifeGuide Key inserted between
the two.  When the infrared energy generated by the source passes through the
sample window, glucose in

                                      -4-
<PAGE>
 
the ISF sample absorbs part of the energy in a manner that is detected, measured
and displayed by the LifeGuide Meter.

     THE LIFEGUIDE SYSTEM

     The Company's LifeGuide System will be comprised of (i) the LifeGuide
Meter, a hand-held, battery-powered monitor, and (ii) the LifeGuide Key, a
single-use, disposable sample collection device.

     The LifeGuide Meter will be an integrated, compact, easy-to-use glucose
monitoring device similar in size to the handset of a telephone. The LifeGuide
Meter will consist of an infrared source and detector, an easy-to-read LCD
display screen, a port for the disposable LifeGuide Key and buttons to access
memory and other functional modes. The proposed LifeGuide Meter will have visual
and audible prompts to assist the user through the sampling process. The
LifeGuide Meter will have the ability to indicate when an appropriate sample has
been obtained and to self-diagnose any electronic malfunction. In addition, the
LifeGuide Meter will be capable of a wireless transmission of data to a personal
computer for review and analysis by the user's physician.

     The single-use, disposable LifeGuide Key is designed to be easily handled
by the user and inserted into the LifeGuide Meter. The proprietary design of the
LifeGuide Key will allow for the capture of the required ISF sample and the
retention of the sample during the measurement and disposal process. The
LifeGuide Key contains a very small needle that is used to draw a sub-microliter
sample across a specially designed membrane window through which a sample can be
read. The LifeGuide Key, which will be packaged in a sterile pouch, will be
similar in size to an average house key.

     To operate the LifeGuide System, the user will insert the LifeGuide Key
into the LifeGuide Meter and hold the LifeGuide System against the skin until
the LifeGuide Meter indicates the sampling process is complete. Individuals who
have tried the LifeGuide System have indicated that the physical sensation is
like pressing a ballpoint pen, with the point retracted, against the skin. The
Company estimates that the average sampling time will be from 20 to 30 seconds
depending on the user and the location of sampling. Shortly after the sampling
process is complete, the LifeGuide System will display the user's glucose level.
Because the ISF sample captured by the LifeGuide Key will not come into contact
with the LifeGuide Meter, there will be no need to clean the LifeGuide Meter
after each use. The Company will also offer a control solution that will allow
the user to confirm that the LifeGuide System is functioning properly.

     The Company believes the LifeGuide System will offer significant advantages
over commercially available personal blood glucose monitoring systems and
alternative non-invasive technologies under development, including the
following:

     .    Eliminates the Pain of Lancing the Fingertips--The LifeGuide System is
          designed to allow for the accurate measurement of glucose levels
          without the pain of a finger lance. Unlike most commercially available
          glucose monitoring systems which involve penetrating the deeper layers
          of the skin to obtain a blood sample, the LifeGuide System's
          proprietary sampling method draws from only the outermost layers of
          the skin and avoids the areas of high nerve density. This sampling
          technology eliminates the pain associated with conventional "finger-
          stick" sampling approaches.

     .    Bloodless Approach--The LifeGuide System is designed to allow for the
          accurate measurement of glucose levels without drawing blood. This
          bloodless approach eliminates the mess and inconvenience of handling a
          blood sample and the negative perceptions associated with visible
          blood. The elimination of the need for a blood sample will allow
          people with diabetes to use the proposed LifeGuide System discretely
          in any environment.

     .    Sampling Flexibility--The LifeGuide System is designed to be used on
          skin almost anywhere on the body, not merely areas (such as the
          fingertips) where blood capillaries and nerve endings are
          concentrated.

                                      -5-
<PAGE>
 
     .    Ease of Use--The Company's proposed LifeGuide System will eliminate
          some of the steps required by commercially available personal blood
          glucose monitoring systems. With most current systems, after lancing
          the finger, a drop of blood must be directed to a small target zone on
          a thin, difficult to handle strip. The Company has designed the
          LifeGuide Key to be easily handled and inserted into the LifeGuide
          Meter. The sampling procedure of the proposed LifeGuide System has
          been reduced to simply holding the device against an area of exposed
          skin until an adequate sample has been obtained (20 to 30 seconds) and
          waiting briefly for a displayed result.

     .    Cost Competitive--Unlike some alternative non-invasive technologies
          under development, it is anticipated that the proposed LifeGuide
          System will be offered at competitive prices and will not be a
          significant departure from current consumer buying patterns and
          reimbursement practices with respect to commercially available
          personal glucose monitoring systems.

     Because of these potential advantages, the Company believes that the
proposed LifeGuide System may facilitate greater compliance with the
recommendations of the DCCT panel.

RESEARCH AND DEVELOPMENT

     To date, the Company has been engaged primarily in the research,
development and testing of the LifeGuide System. Since inception, the Company
has incurred approximately $9.6 million in research and development expenses.
The Company spent approximately $4.2 million, $2.5 million and $1.6 million
during fiscal years 1996, 1995 and 1994, respectively, on research and
development, all of which was sponsored by the Company. The Company believes
that it is in the final stages of its product development and expects to
finalize development of its first commercial LifeGuide System in 1997.

     In 1994, the Company used benchtop prototypes incorporating the functional
components of its LifeGuide System and standard laboratory electronics to
demonstrate that ISF glucose values correlate closely to blood glucose values
obtained with commercially available personal blood glucose monitors. In
addition, the Company has conducted studies using a fully-integrated hand-held
prototype of the LifeGuide System incorporating all of the final components of
the LifeGuide System (including battery-powered electronics) to demonstrate the
accuracy of the LifeGuide System when testing samples containing known glucose
values. The Company is continuing to work on optimizing the performance of the
LifeGuide System and expects to finalize the development of a commercial
prototype of the LifeGuide Meter during 1997.

     The Company's success will be dependent upon its ability to finalize the
commercial design and then manufacture the LifeGuide System in compliance with
regulatory requirements, in a timely manner and in sufficient quantities while
maintaining product quality and acceptable cost. The personal glucose monitoring
products market is characterized by commercial products which are manufactured
in large quantities at very low cost. As a result, the present focus of the
LifeGuide Meter development effort is to finalize the design of the fully-
integrated prototype into a hand-held, battery-powered final product that can be
reliably and cost-effectively manufactured. The development of the LifeGuide Key
was completed in 1996. Both the LifeGuide Meter and the LifeGuide Key are being
designed to use materials and components that can be easily produced by
suppliers with a minimum of customization.

CLINICAL TESTING

     The goal of the Company's clinical testing to date has been to demonstrate
the correlation between ISF glucose levels and blood glucose levels, and to test
the final components of the LifeGuide System for accuracy and precision. All ISF
samples used in this testing have been obtained utilizing the Company's
proprietary sampling method.

                                      -6-
<PAGE>
 
     In December 1994, the Company undertook a program of testing people with
diabetes under a protocol reviewed and approved by the International Diabetes
Center, a diabetes research and treatment center located in Minneapolis,
Minnesota. This testing program was designed to evaluate the correlation between
the results obtained using (i) benchtop prototypes of the Company's LifeGuide
System incorporating the functional components of its LifeGuide System and
standard laboratory electronics, (ii) a standard laboratory assay for measuring
glucose levels in venous blood and (iii) the leading conventional personal blood
glucose monitoring system. The results of this study demonstrated that ISF
glucose levels closely correlate to blood glucose levels and that the glucose
values obtained with benchtop prototypes of the LifeGuide System closely
correlate to those obtained with commercially available blood glucose monitors.

     In early 1996, additional clinical studies were conducted at the Mayo
Clinic and the University of Minnesota. Both of these studies used the LifeGuide
System to obtain samples of ISF and a standard laboratory assay for measuring
glucose levels in venous blood and in ISF. The Mayo Clinic study provides
publishable support for the conclusion that there is a strong correlation
between the glucose levels in ISF and the glucose levels in blood when the
glucose levels are in a relatively steady state. This study compared the ISF and
blood glucose values in 66 individuals and yielded a correlation coefficient of
0.96 (on a 0.0 to 1.0 scale, with 1.0 representing a perfect correlation). The
University of Minnesota study provides publishable support for the conclusion
that there is a strong correlation between the glucose levels in ISF and the
glucose levels in blood when the glucose levels are in a state of rapid change.
This study has compared the ISF and blood glucose values in 17 individuals with
Type I diabetes over a five-hour period of rising and falling glucose values.
Cumulative data from these 17 subjects has yielded a correlation coefficient of
0.95.

     In the first half of 1996, the Company also conducted studies using a
benchtop prototype of the LifeGuide System incorporating all of the final
components of the LifeGuide System (including battery-powered electronics) to
compare the glucose values obtained using the LifeGuide System to the known
glucose values in the sample. This testing, performed on over 70 samples,
yielded a correlation coefficient of 0.99.

     In the fourth quarter of 1996, the Company conducted additional studies
using a fully-integrated hand-held prototype of the LifeGuide System to compare
the glucose values obtained using the LifeGuide System to the known glucose
values in the sample. This testing, performed on 345 samples, also yielded a
correlation coefficient of 0.99. The Company is continuing to work on optimizing
the performance of the LifeGuide System and expects to conduct additional
testing when the design is finalized.

     The Company plans to use commercial prototypes of the LifeGuide System
(expected to be available in 1997) to obtain patient-generated clinical data in
a three-center, 300 patient trial for use in the Company's application to the
FDA for a 510(k) clearance to market the LifeGuide System. The Company presently
plans to submit this application to the FDA in late 1997.

     To date, testing of the LifeGuide System has been performed solely by
Company personnel under controlled circumstances.  Initial testing was performed
on benchtop prototypes, and in late 1996, the Company initiated testing using
fully integrated, hand-held prototypes of the LifeGuide System.  There can be no
assurance that the Company will not encounter problems in clinical testing which
will cause the Company to delay commercialization of the LifeGuide System, and
there can be no assurance that the commercial version of the LifeGuide System
will prove to be accurate and reliable on a consistent basis.  Even if accurate
and reliable, there can be no assurance that such testing will show the
Company's product to be safe or cost effective.

                                      -7-

MANUFACTURING

     The LifeGuide System is designed to be economically produced using proven
manufacturing methods and equipment. As part of its design strategy, the Company
has consulted with component suppliers, automation firms and OEM electronics
manufacturers.

     The Company currently plans to utilize an outside manufacturer to assemble
the LifeGuide Meter. This manufacturer will be used to build all prototypes of
the LifeGuide Meter for testing and to develop test methods and equipment for
the Company. Most of the components in the LifeGuide Meter will be standard, 
off-the-shelf components. In order to control margins, quality and supply, the
LifeGuide Key will be assembled by the Company at its facilities from components
obtained from outside suppliers. The LifeGuide Key has been designed to minimize
the number of required components and to use components that can be purchased
from suppliers with experience in high volume, medical product manufacturing. In
manufacturing the LifeGuide Key, the Company will use assembly, test and
packaging equipment employing well-known processes similar to those used for
other high speed assembly applications.

     One component of the LifeGuide Meter is available from a single source, as
is one component of the LifeGuide Key. In the event that the Company is unable
to obtain either of these components from their respective suppliers, the
Company would be required to make modifications to its existing LifeGuide System
and to obtain alternative components from alternative suppliers. Although the
Company believes that it can enter into supply agreements with respect to these
components, any interruption in the supply of either of these components would
have a material adverse effect on the Company's business, financial condition
and results of operation.

     The Company expects that its most significant manufacturing challenge will
be to quickly increase LifeGuide Key production volumes after the full-scale
commercial introduction of the LifeGuide System. To address this challenge, the
Company anticipates installing and qualifying an initial automated manufacturing
line prior to installation of additional production lines. After the
installation, evaluation and refinement of the initial line are completed, the
Company anticipates incrementally adding several full-scale commercial
production lines with greater manufacturing capability.

     The Company ordered the initial automated manufacturing line for the
LifeGuide Key in late 1996 and anticipates producing initial LifeGuide Keys from
this line in late 1997. There can be no assurance that the Company will be able
to achieve and maintain product quality and reliability when producing the
LifeGuide System in the quantities required for commercial operations or within
a period that will permit the Company to introduce its products in a timely
fashion, nor that the Company will be able to assemble and manufacture its
products at an acceptable cost.

SALES AND MARKETING

     The Company intends to direct its sales and marketing efforts at people
with diabetes who use insulin to control their glucose levels, because they tend
to monitor their blood glucose more frequently. The Company believes that
insulin users are more likely to be better educated concerning their condition,
are more motivated to comply with proper disease management and are most likely
to recognize the potential benefits of the LifeGuide System. The Company will
seek to gain product acceptance by implementing a strategy that both promotes
the Company's products directly to people with diabetes and educates healthcare
professionals, managed care decision makers and insurers as to the potential
advantages of the LifeGuide System in facilitating compliance with the
recommendations of the DCCT panel. As part of its education and awareness
strategy, the Company will focus on developing peer reviewed journal articles
authored by leading experts in diabetes, sponsoring publication of papers based
on research covering performance and utility benefits of the LifeGuide System
and conducting regional seminars.

                                      -8-
<PAGE>
 
     Initially, the Company intends to use various direct marketing methods to
promote its LifeGuide System to people with diabetes, including direct mail,
advertisements in healthcare media and internet and on-line computer services.
In addition, the Company expects to utilize other emerging distribution
channels, including those supporting managed care organizations, on-line
merchandising services and direct distribution firms. The Company will sell the
LifeGuide System directly to consumers through a toll-free number and will
support these sales with a customer service organization. As the Company's
customer base grows, the Company expects to utilize traditional retail
distribution channels, including chain and independent drug stores and other
retail outlets. The Company expects eventually to market and distribute its
products outside the United States through third party distribution channels.

     The Company intends to introduce the LifeGuide System in the United States
in two phases: (1) a limited introduction phase, expected to commence in 1998,
subsequent to obtaining 510(k) clearance from the FDA; and (2) a full commercial
introduction phase, expected to commence several months thereafter. During the
limited introduction phase, the Company expects to use an experienced direct
sales force to introduce the LifeGuide System to key opinion leaders in the
treatment of diabetes for use in their practices on a selected number of
patients. In addition, during this phase the Company expects to market to
selected managed care organizations. The primary purpose of the limited
introduction phase is to ensure that the Company's infrastructure will support
full commercial introduction.

     During the full commercial introduction phase, the Company plans to utilize
a three-pronged strategy employing a highly trained and focused direct sales
force. One specialized sales group will concentrate on promotion of the
Company's products to managed care decision makers and insurers. A second group
will promote the Company's products to healthcare professionals and
organizations that influence patient choices. A third specialized sales group
will target the retail distribution channel.

     The Company has no experience in marketing the LifeGuide System and has not
yet entered into any marketing or distribution arrangements for the LifeGuide
System. There can be no assurance that the Company will be able to build a
suitable sales force or enter into satisfactory marketing arrangements with
third parties when commercial potential develops, or that its sales and
marketing efforts will be successful.

PATENTS AND PROPRIETARY RIGHTS

     The Company's success will depend in part on its ability to obtain patent
protection for its proposed products and processes, to preserve its trade
secrets and to operate without infringing the proprietary rights of third
parties. The Company pursues a policy of seeking patent protection for each of
the areas of invention embodied in the LifeGuide System. The Company has one
issued United States patent relating to the method of drawing an ISF sample from
the outer layers of the skin, and five additional United States patent
applications directed toward various aspects of the technologies underlying the
LifeGuide System. The Company has also filed three corresponding PCT foreign
patent applications to seek similar patent protection outside the United States.

     The Company has implemented a strategy of pursuing patent applications to
provide both design freedom and protection from competitors. This strategy
includes evaluating and seeking patent protection both for inventions most
likely to be used in the Company's LifeGuide System and for related inventions
likely to be used by others as competing alternatives.

     The Company also relies upon trade secrets and proprietary know-how in its
manufacturing processes. The Company requires each of its employees,
consultants, advisors and certain of its vendors to execute a confidentiality
agreement upon the commencement of their relationship with the Company.

                                      -9-
<PAGE>
 
     No assurance can be given that any additional patents will be issued, that
the scope of any patent protection granted to the Company will exclude
competitors or that any of the Company's patents will be held valid or
enforceable if subsequently challenged. Patenting medical devices involves
complex legal and factual questions, and there is no consistent policy regarding
the breadth of claims which issue pertaining to such technologies. The Company
also relies upon unpatented trade secrets, and no assurance can be given that
others will not independently develop or otherwise acquire technologies
substantially equivalent to those of the Company. In addition, even if the
patents the Company has applied for are ultimately issued, others may hold or
receive patents that contain claims covering the products proposed to be sold by
the Company and which may delay or prevent the sale of the LifeGuide System or
require licenses resulting in the payment of fees or royalties by the Company in
order for the Company to carry on its business. There can be no assurance that
needed or potentially useful licenses will be available in the future on
acceptable terms or at all.

     There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry. Litigation could
result in substantial costs to and a diversion of effort by the Company, but may
be necessary to enforce any patents issued to the Company, protect trade secrets
or know-how owned by the Company, defend the Company against claimed
infringement of the rights of others or determine the scope and validity of the
proprietary rights of others. The Company is not currently a party to any patent
or other litigation. The Company routinely monitors patent issuances by others
in its industry, and in 1996 became aware of a patent that may relate to a
feature of the LifeGuide System. The Company engaged outside patent counsel to
review the patent, and such counsel rendered its opinion to the Company that the
patent is not infringed by the Company's technology. In addition, such counsel
advised the Company that if the patent was challenged, those claims which the
Company believes may apply to the LifeGuide System would be likely to be held
invalid based on the existence of prior art not cited by the patent examiner.
There can be no assurance, however, that the holder of the patent will not
pursue litigation which could be costly to the Company. An adverse determination
in any litigation, including any litigation commenced by the holder of the
patent referred to above, could subject the Company to significant liabilities
to third parties, require the Company to seek licenses from or pay royalties to
third parties or prevent the Company from manufacturing, selling or using its
proposed products, any of which could have a material adverse effect on the
Company's business and prospects.

THIRD PARTY REIMBURSEMENT

     Private insurance companies, self-insured employers, health maintenance
organizations and governmental payors under Medicare and Medicaid programs are a
source of reimbursement to users of blood glucose monitoring systems and related
products, but there is no uniform policy on reimbursement among third-party
payors. Sales of the Company's proposed products in certain markets will be
dependent in part on availability of adequate reimbursement from these third-
party payors. Although the Company believes that current reimbursement levels
are adequate to support the introduction of the LifeGuide System, third-party
payors are increasingly challenging the pricing of medical products and
services. There can be no assurance that adequate levels of reimbursement will
be available to enable the Company to achieve market acceptance of the LifeGuide
System or maintain price levels sufficient to realize an appropriate return on
its investment in the development or manufacture of the LifeGuide System.
Without adequate support from third-party payors, the market for the Company's
products may be limited.

     The Medicare program reimburses people with diabetes for one meter and for
a one month's supply of test strips at a time as approved by their physicians.
In 1996, the Health Care Financing Administration ("HCFA"), which sets rates for
the Medicare program, set a payment limit of $61.99 for personal blood glucose
monitors and set the maximum reimbursement rates for a box of 50 test strips at
between $33.75 to $39.70, depending on the state in which the reimbursement is
sought. The Office of the Inspector General of the United States Department of
Health and Human Services (the "OIG") is currently conducting a survey to
determine more economical methods of providing blood glucose test strips to
Medicare beneficiaries. These payment limits and initiatives may lead to
increased pricing

                                      -10-
<PAGE>
 
pressures among manufacturers of existing blood glucose meters and test strips.
The Company's business, financial condition and results of operations could be
adversely affected by the continuing efforts of governmental and private payors
to reduce the costs of healthcare by lowering reimbursement rates.

     As a provider of products that are reimbursed by Medicare, Medicaid and
other third-party payors, the Company will be subject to the anti-kickback
provisions of the Medicare and Medicaid fraud and abuse laws and similar state
laws. These laws prohibit the exchange of remuneration for referrals of services
or products reimbursed by Medicare and Medicaid or other third-party payors.
Violations of these prohibitions may result in civil and criminal penalties and
exclusion from the Medicare and Medicaid programs. The Company intends to comply
with the federal anti-kickback statute and related safe harbor regulations
regarding discount disclosures.

COMPETITION

     The Company believes that its success will depend primarily upon its
ability to create and deliver a glucose monitoring system, on a timely basis and
at a competitive price, that avoids the pain and blood associated with current
glucose monitoring products. In addition, the Company must effectively create
market awareness and acceptance of its products and maintain the proprietary
nature of its technologies and processes. The glucose monitoring industry is
characterized by intense competition and is currently dominated by several
companies with established products and distribution channels. There are
currently four significant competitors in the worldwide blood glucose monitoring
market: LifeScan, Inc., a subsidiary of Johnson & Johnson, Inc.; Boehringer
Mannheim Corporation, a subsidiary of Boehringer Mannheim GmbH; Bayer
Diagnostics, a division of Bayer AG; and Medisense, Inc. (a subsidiary of Abbott
Laboratories).

     Companies in the glucose monitoring market compete on the basis of
innovative technology, ease of use, price, product reliability and acceptance by
consumers and healthcare professionals.  Price competition for the placement of
monitors in the glucose monitoring market is intense and involves marketing
tactics such as rebates, trade-in offers and volume purchase incentive programs.
This price competition could result in reductions of the prices of the Company's
LifeGuide Meter and the use of purchase incentive programs that could adversely
affect the Company's revenues and profitability.

     A number of entities are conducting research on possible non-invasive and
minimally invasive methods of determining glucose levels. Data regarding the
precise progress of these companies with respect to these alternative
technologies has not generally been made public.

     There can be no assurance that the Company's competitors and potential
competitors will not succeed in developing or marketing technologies and
products that will be more accepted in the marketplace than the proposed
LifeGuide System or that would render the Company's technology and proposed
products obsolete or noncompetitive.  Most of the Company's competitors and
potential competitors have substantially greater capital resources, research and
development staffs and facilities than the Company.  In addition, most of the
Company's competitors and potential competitors have substantially greater
experience than the Company in research and new product development, obtaining
regulatory approvals and manufacturing and marketing medical devices.

     Numerous researchers are also investigating alternative treatments or cures
for diabetes. If any of these efforts are successful in reducing the
complications associated with diabetes and can be cost-effectively provided to
people with diabetes, the need for the Company's products could be mitigated or
become entirely nonexistent.

GOVERNMENT REGULATION

     Government regulation in the United States and other countries is a
significant factor in the Company's business.  The Company's products will be
regulated by the FDA under a number of statutes including the Federal Food, Drug
and Cosmetic Act, as amended (the "FDC Act"), and the Safe Medical

                                      -11-
<PAGE>
 
Devices Act of 1990 (the "SMDA"). Manufacturers of medical devices must comply
with applicable provisions of the FDC Act and the SMDA and certain associated
regulations governing the development, testing, manufacturing, labeling,
marketing and distribution of medical devices and the reporting of certain
information regarding their safety. Both the FDC Act and the SMDA require
certain clearances from the FDA before medical devices, such as the Company's
proposed LifeGuide System, can be marketed.

     FDA permission to distribute a new device can be obtained in one of two
ways. If a new or significantly modified device is "substantially equivalent" to
an existing legally marketed device, the new device can be commercially
introduced after filing a 510(k) premarket notification with the FDA and the
subsequent issuance by the FDA of an order permitting commercial distribution.
Changes to existing devices that do not significantly affect safety or
effectiveness may be made without an additional 510(k) notification. The Company
believes and has confirmed with the FDA that the LifeGuide System will be
eligible for 510(k) clearance with the predicate device being a commercially
available personal blood glucose monitoring instrument.

     A second, more comprehensive approval process applies to a new device that
is not substantially equivalent to an existing product. First, the applicant
must conduct clinical trials in compliance with testing protocols approved by an
institutional review board for the participating research institution. Second, a
Premarket Approval application ("PMA") must be submitted to the FDA that
describes the results of the clinical trials, the device and its components, the
methods, facilities and controls used for its manufacture, proposed labeling and
the demonstration that the product is safe and effective. Finally, the
manufacturing site for the product subject to the PMA must pass an FDA
preapproval inspection. The Company does not believe that its planned products
will require PMA approval, although there can be no assurance that such an
approval will not be required. If required, obtaining a PMA approval will result
in significant delays in and could prevent the introduction of the Company's
products.

     In connection with either a 510(k) notification or a PMA, clinical testing
of a "significant risk" device requires the submission to the FDA of an
investigational device exemption ("IDE") application. An IDE application is not
required for a "nonsignificant risk" ("NSR") device. The Company believes that
the proposed LifeGuide System is an NSR device and therefore does not require an
IDE application. However, in the event that the FDA should require the Company
to submit an IDE application, the Company may be required to repeat all or part
of the clinical testing conducted prior to obtaining an IDE, which may delay
approval of the LifeGuide System.

     FDA clearances, if obtained, are subject to continual review, and if the
FDA believes that the Company is not in compliance with the FDC Act, the SMDA or
their associated regulations, it can institute proceedings to detain or seize
the Company's products, require a recall, enjoin future violations and assess
civil and criminal penalties against the Company, its directors, officers or
employees. The FDA may also withdraw market approval for the Company's products
or require the Company to repair, replace or refund the cost of any device
manufactured or distributed by the Company.

     The FDC Act will regulate the Company's development, quality control and
manufacturing procedures by requiring the Company to demonstrate compliance with
current Good Manufacturing Practices. The FDA monitors compliance with these
requirements by requiring manufacturers to register with the FDA, which subjects
them to periodic FDA inspections of their manufacturing facilities. In order to
ensure compliance with these requirements, the Company will be required to
expend time, resources and effort in the areas of production and quality
control. If violations of the applicable regulations are noted during FDA
inspections, the continued marketing of any products manufactured by the Company
may be adversely affected.

     The Company also plans eventually to market the LifeGuide System in several
foreign markets. No regulatory approvals have yet been obtained in any such
countries and there is no assurance that any will be issued. Requirements
pertaining to the LifeGuide System will vary widely

                                      -12-
<PAGE>
 
from country to country, and involve anything from simple product registrations
to detailed submissions similar to those required by the FDA.

EMPLOYEES

     As of March 1, 1997, the Company had a total of 70 full-time employees. The
Company also had consulting or other contract arrangements with 19 persons on a
full- or part-time basis. Of this total workforce, 46 persons were engaged in
research and development activities, 16 persons in manufacturing development, 3
persons in sales and marketing, 13 persons in clinical, regulatory and quality
functions and 11 persons in support and administrative functions. None of the
Company's employees is covered by a collective bargaining agreement, and the
Company believes that it maintains good relations with its employees.

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

GENERAL

          Integ, a development stage company, was incorporated on April 3, 1990
to develop the LifeGuide System, a next generation hand-held glucose monitoring
product for use by people with diabetes that avoids the pain and blood
associated with conventional "finger-stick" technologies. Utilizing the
Company's proprietary interstitial fluid sampling technology, the LifeGuide
System will allow people with diabetes to frequently self-monitor their glucose
levels without repeatedly enduring the pain of lancing their fingers to obtain a
blood sample.

RESULTS OF OPERATIONS

          From inception through December 31, 1996, the Company has incurred
losses totaling $18,873,957, consisting of $9,626,514 of research and
development expenses, $5,858,395 of general and administrative expenses and
$3,389,048 of other expenses net of interest income. The Company's activities
have consisted primarily of research and product development, product design,
fund raising and determination of the manufacturing processes and marketing
strategies needed for the introduction of the LifeGuide System planned for 1998.
The Company has generated no revenue and has sustained significant operating
losses each year since inception. The Company expects such losses to continue
through 1999 and to increase at least through the end of 1998.

          General. Net losses increased to $9,083,432 during 1996, up from
$5,048,730 during 1995 and $2,492,220 during 1994.

          Research and development expenses. Research and development expenses
increased to $4,191,547 during 1996 from $2,462,868 during 1995 and $1,568,220
during 1994. The increases in research and development expenses were due
primarily to increases in compensation, benefit and employee recruiting costs
and from increases in the cost of prototype materials purchased, consulting
expenses and patent legal fees.

          General and administrative expenses. General and administrative
expenses increased to $2,784,769 during 1996 from $1,417,365 during 1995 and
$792,017 during 1994. The increases in general and administrative expenses were
due to increases in compensation, facility costs and depreciation of furniture
and equipment. In addition, in 1996, the increase in general and administrative
expenses was impacted by the various legal, insurance and filing costs of being
a publicly traded company.

          Clinical and regulatory expenses. Clinical and regulatory expenses
increased to $648,678 during 1996 from $297,580 during 1995 and $52,083 during
1994. The increases were due primarily to increases in compensation and benefit
costs and consulting expenses incurred to plan the clinical testing necessary to
obtain the required regulatory approvals.

          Manufacturing development expenses. Manufacturing development expenses
increased to $1,377,121 during 1996 from $718,316 during 1995 and $55,430 during
1994. The increases were due primarily to increases in pre-manufacturing
expenses, consisting of compensation and recruiting costs and consulting
expenses incurred to plan and design the Company's automated manufacturing
processes.

          Sales and marketing expenses. Sales and marketing expenses increased
to $917,840 during 1996 from $384,722 during 1995 and $54,409 during 1994. The
increases were due primarily to compensation and recruiting costs and product
design and market research costs. In addition, in 1996, the Company incurred
additional expenses associated with its Medical and Diabetes Educator Advisory
Boards.

          Interest income. Interest income increased to $1,306,460 during 1996
from $580,840 during 1995 and $45,112 during 1994. The increase in 1996 was
primarily due to the investment in commercial paper and government securities of
the net proceeds totaling $26.1 million on July 1, 1996 from the Company's
initial public offering. The increase in 1995 was due primarily to the
investment in government securities of the proceeds from the sale of the
Company's Preferred Stock.

LIQUIDITY AND CAPITAL RESOURCES

          The Company's operations since inception have been funded primarily by
net proceeds from the sale of Common and Preferred Stock totaling approximately
$52 million through December 31, 1996. As of December 31, 1996, the Company had
cash and cash equivalents of $33.8 million and working capital of $32.9 million.

          On July 1, 1996, the Company received net proceeds of approximately
$26.1 million from the initial public offering of 3,000,000 shares of its common
stock. The Company will use the proceeds from this offering, along with its
existing cash, to fund the continued development and testing of and clinical
trials for the LifeGuide System, including research and development,
manufacturing and marketing activities related to the market launch of the
LifeGuide System. The Company invests excess cash in short-term, interest-
bearing, investment grade securities.

          On March 27, 1996, the Company executed an equipment loan agreement
which provided for borrowings of up to $5,000,000 under a line of credit. In
July 1996, the lender committed to a total line of $12,500,000 to finance the
purchase of furniture and equipment, including automated manufacturing equipment
and tooling. The line of credit expires December 31, 1998, and $1.4 million was
borrowed under the line as of December 31, 1996.
    
          The Company believes that its current cash balances, when combined
with the $11 million unused portion of its line of credit facility, will be
sufficient to fund its operations until the second quarter of 1998. The
Company's future liquidity and capital requirements will depend on numerous
factors, including the extent to which the Company's LifeGuide System gains
market acceptance, the timing if regulatory actions regarding the LifeGuide
System, the costs and timing of expansion of sales, marketing and manufacturing
activities, the results of clinical trials and competition. See Exhibit 99.1 to
this Form 10-K/A for a more detailed description of the factors that may affect
the Company's future liquidity and capital requirements.      

          The Company believes that inflation has not had a material impact on
its operation or liquidity to date.

                         Report of Independent Auditors


Board of Directors
Integ Incorporated

We have audited the accompanying balance sheets of Integ Incorporated (a
development stage company) as of December 31, 1996 and 1995 and the related
statements of operations, changes in shareholders' equity (deficiency) and cash
flows for each of the three years in the period ended December 31, 1996, and for
the period from April 3, 1990 (inception) to 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 Integ Incorporated at December
31, 1996 and 1995 and the results of its operations and its cash flows for each
of the three years in the period ended December 31, 1996, and for the period
from April 3, 1990 (inception) to December 31, 1996, in conformity with
generally accepted accounting principles.

1.   DESCRIPTION OF BUSINESS

Integ Incorporated was formed in April 1990 and is a development stage company
engaged in the development of a hand-held glucose monitoring product for use by
people with diabetes that avoids the pain and blood associated with conventional
"finger stick" technology. Utilizing the Company's proprietary interstitial
fluid sampling technology, the Lifeguide System will allow people with diabetes
to frequently monitor their glucose levels without repeatedly enduring the pain
of lancing their fingers to obtain a blood sample.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

STOCK COMPENSATION PLANS

The Company follows Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees ("APB 25"), and related interpretations in accounting
for its stock options. Under APB 25, when the exercise price of stock options
equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation
("Statement 123"). The Company adopted the disclosure only provisions of
Statement 123. Accordingly, the Company has made pro forma disclosures of what
net loss and loss per share would have been had the provisions of Statement 123
been applied to the Company's stock options.

NET LOSS PER SHARE

Net loss per share is computed using the weighted average number of shares of
common stock outstanding during the periods presented. Pursuant to Securities
and Exchange Commission Staff Accounting Bulletin No. 83 ("SAB No. 83"), shares
convertible into common stock issued by the Company at prices less than the
initial offering price during the 12 months immediately preceding the initial
public offering, plus stock options and warrants granted at exercise prices less
than the initial public offering price during the same period, have been
included in the determination of shares used in calculating the net loss per
share, using the treasury stock method, as if they were outstanding for all
periods presented prior to the initial public offering.

Fully diluted net loss per share computed in accordance with Accounting
Principles Board Opinion No. 15 and SAB No. 83, gives effect to the conversion
of all series of convertible preferred stock into common stock for the years
ended December 31, 1994, 1995 and 1996, as if conversion had occurred as of the
beginning of the earliest period presented.

AUTOMATIC CONVERSION OF PREFERRED STOCK

Upon the closing of the initial public offering on July 1, 1996, all outstanding
shares of convertible preferred stock were automatically converted into an
aggregate of 5,835,705 shares of common stock.

RECLASSIFICATIONS

Certain amounts in the 1995 financial statements have been reclassified to
conform with the 1996 presentation.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

3.   LONG-TERM DEBT AND LEASES

The Company leases its office facility and certain office equipment under
operating leases. Rent expense of $96,403, $251,724 and $369,880 was recorded
for noncancelable operating leases and sub-leases for the years ended
December 31, 1994, 1995 and 1996, respectively. Future minimum lease commitments
for operating leases with remaining terms in excess of one year, excluding
executory costs such as real estate taxes, insurance and maintenance expense,

4.   REDEEMABLE CONVERTIBLE PREFERRED STOCK AND PREFERRED STOCK
  
During June 1995, all holders of Series A, B, C and D Convertible Preferred
Stock agreed to cancel the redemption privileges.
  
Series A, B, C, D and E Convertible Preferred Shares were automatically
converted three shares of preferred into two shares of common stock upon the
closing of the public offering of the Company's securities on July 1, 1996.
    
During June 1995, the Company received net proceeds of $20,557,452 from the sale
of 5,604,655 shares of its Series E Convertible Preferred Stock, Class 1. During
January 1995, in anticipation of this pending offering, the Company received
proceeds of $2,900,000 and issued one-year, 8.5% promissory notes under a bridge
loan arrangement with certain investors, including $1,500,000 received from
Medical Innovation Fund II (MIF II) and $500,000 received from Artesian
Management, Inc. (Artesian), both significant shareholders of the Company. Upon
consummation of the offering during June 1995, these promissory notes and all
accrued interest thereon totaling $2,987,620 were automatically converted into
746,905 shares of Series E Convertible Preferred Stock, Class 1, at $4.00 per
share. In connection with such bridge financing, investors received warrants for
the purchase of 429,630 shares of Series E Convertible Preferred Stock, Class 2,
at $3.375 per share (convertible into 286,420 shares of Common Stock at $5.06
per share), including warrants for 222,222 shares issued to MIF II and warrants
for 74,074 shares issued to Artesian. The liquidating preference of the Series E
Convertible Preferred Stock, Class 2, is $3.375 per share. The Company has
included $179,800 as additional interest expense during the year ended December
31, 1995 which represents the value of the warrants issued in connection with
the bridge loan (see Note 6).

5.   UNDESIGNATED CAPITAL STOCK AUTHORIZATION AND STOCK SPLIT

STOCK AUTHORIZATION AND STOCK SPLIT

On April 24, 1996, the Board of Directors approved a reverse stock split of 2-
for-3 for the Company's common stock. Accordingly, all share, per share,
weighted average share, and stock option information has been restated to
reflect the split. The reverse stock split impacted the conversion prices of the
preferred stock and the numbers of shares of common stock into which the
preferred stock will convert but had no effect upon the numbers of preferred
stock warrants and shares of preferred stock issued and outstanding.
Accordingly, all preferred stock and preferred stock price amounts have not been
adjusted for the reverse stock split. In addition, the Board of Directors
approved an increase in the authorized shares of capital stock to 25,000,000,
including 20,000,000 shares of common stock and 5,000,000 shares of undesignated
preferred stock.

6.   STOCK OPTIONS AND WARRANTS

STOCK OPTIONS AND RESTRICTED STOCK GRANT

The Company has 1990, 1991 and 1994 stock option plans which provide for the
issuance of incentive and nonqualified stock options and restricted stock grants
to employees and consultants. Under the plans, the exercise price of options
granted is determined by the Company's Board of Directors, but incentive stock
options must be granted at exercise prices equal to the fair market value of the
Company's stock as of the grant date. A total of 2,213,333 shares of the
Company's common stock have been reserved for issuance under all three plans as
of December 31, 1996. During April 1996 the Board of Directors approved an
increase in the number of shares authorized for issuance under the 1994 plan by
1,000,000 shares and adopted the 1996 Directors' Stock Option Plan for which
300,000 shares are reserved.

6.   STOCK OPTIONS AND WARRANTS (CONTINUED)

During 1991 and 1993, the Company granted options outside the plans to purchase
42,993 shares of the Company's common stock at $.83 per share to Medical
Innovation Fund ("MIF"), a significant shareholder of the Company (see Note 8).

Options outstanding expire at various dates during the period from October 2000
through December 2006. Exercise prices for options outstanding as of December
31, 1996 ranged from $.83 to $12.25 per share. The number of options exercisable
as of December 31, 1994, 1995 and 1996 were 235,484, 295,427 and 481,736,
respectively, at weighted average prices of $.84, $.94 and $2.38 per share,
respectively.

The weighted-average grant date fair value of options granted at market prices
during the years ended December 31, 1995 and 1996 was $.62 and $7.18 per share,
respectively. The weighted-average grant date fair value of options granted
below market prices during the years ended December 31, 1995 and 1996 was $4.01
and $6.93 per share, respectively.

The Company has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees ("APB 25") and related Interpretations
in accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FASB Statement No. 123,
Accounting for Stock-Based Compensation ("Statement 123"), requires use of
option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, if the exercise price of the Company's employee
stock options equals the market price of the underlying stock on the date of
grant, no compensation expense is recognized.

Pro forma information regarding net loss per share is required by Statement 123,
and has been determined as if the Company had accounted for its employee stock
options under the fair value method of Statement 123. The fair value for these
options was estimated at the date of grant using the Black-Scholes option
pricing model with the following weighted-average assumptions for 1995 and 1996:
risk free interest rates of 6.37% and 6.59%, respectively; no dividend yield;
volatility factor of the expected market price of the Company's common stock of
56.2% and a weighted-average life of the option of 10 years.

                   Notes to Financial Statements (continued)


6.   STOCK OPTIONS AND WARRANTS (CONTINUED)

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

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period. The Company's pro
forma information is as follows:

Pro forma net loss per common share            $     (1.82)    $     (2.44)    
</TABLE>

The pro forma effect on net loss for 1995 and 1996 is not representative of the
pro forma effect on net loss in future years because it does not take into
consideration pro forma compensation expense related to grants made prior to
1995.

DEFERRED COMPENSATION

During August 1994, the Company issued a restricted stock grant under the
Company's stock option plans to its President and Chief Executive Officer for
183,333 shares of common stock at a fair market value determined to be $.83 per
share in exchange for two promissory notes. The Company recognized $151,250 as
deferred compensation and is amortizing this amount ratably over the restriction
period of three years and, during the year ended December 31, 1995 and 1996,
$109,937 and $38,863 was expensed, respectively. In addition to the shares being
held by the Company until the restriction lapse occurs, the President and Chief
Executive Officer signed two notes in the amount of the fair market value of the
stock grant. For income tax purposes, one note is forgiven

20% per year and the Company will also award this individual an additional bonus
adequate to cover related income taxes due on the note forgiveness.

During 1995 and 1996 options were granted to purchase a total of 433,710 shares
of the Company's common stock at exercise prices below the current market price.
The Company recognized $960,208 and $56,329 during the years ended 1995 and
1996, respectively, as deferred compensation for the excess of the deemed value
for accounting purposes of the common stock issuable upon exercise of such
options over the aggregate exercise price of such options. The deferred
compensation is amortized ratably over the vesting period of the options. For
the years ended 1995 and 1996, $77,169 and $411,797, respectively, was expensed.

During 1996, the Company granted 30,000 options to certain advisors of the
Company. In accordance with FASB 123, the Company recognized $179,600 as
deferred compensation. The deferred compensation is amortized ratably over the
vesting period of the options. In 1996, $65,279 was charged to expense.

The remaining unamortized deferred compensation is expected to be charged to
operations as follows:

1994 the Company issued warrants which expire during May 1999 to a
consultant/stockholder for the purchase of 6,666 shares of common stock

received and was expensed. In addition, during March and December of 1994 and
June 1995 the Company issued warrants for the purchase of 159,042 shares of
Series D Convertible Preferred Stock (convertible into 106,027 shares of common

shares of Series E Convertible Preferred Stock, Class 2, at $3.375 per share
(convertible into 286,420 shares of common stock at $5.06 per share). These

to be $179,800 based on the difference between the stated interest rate and the
Company's estimated effective borrowing rate for the term of the notes and was
expensed as additional interest expense during 1995.

In consideration of the equipment loan agreement discussed in Note 3, the
Company has agreed to issue warrants for the purchase of common stock equal to
8.8% of the total dollar value of the credit line available under the agreement.
Warrants are to be issued as the line is funded, or at the expiration date of
the line in December 1998 for any unfunded portion of the credit line. The value
of these warrants was determined to be $874,416 and will be expensed over the
term of the loan agreement. Each warrant is exercisable initially at $6.00 per
share or, subsequent to any equity financing, at 80% of the per share price of
each subsequent financing, if such occurs. Warrants for the purchase of 18,518
shares of common stock were issued in 1996. These warrants expire in December
2003.

None of the warrants discussed above have been exercised.

7.   INCOME TAXES

The Company has incurred net operating losses since inception. As of December
31, 1996, the Company had net operating loss (NOL) and research and development
tax credit carryforwards of approximately $7,300,000 and $450,000, respectively,
available to offset its future income tax liability. The NOL and tax credit
carryforwards begin to expire in the year 2005. No benefit has been recorded for
such loss carryforwards, and utilization in future years may be limited, if
significant ownership changes have occurred.

Components of deferred tax assets at December 31 are as follows:
