                                  THE COMPANY
 
  Integ Incorporated ("Integ" or the "Company") is developing the Lifeguide
System, a painless and bloodless hand-held glucose monitoring product for use
by people with diabetes. 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
first half of 1997.
 
  It is estimated that there are as many as 100 million people with diabetes
worldwide. In the United States, diabetes is a leading cause of blindness,
kidney failure, amputation and heart failure and the fourth leading cause of
death by disease. Nearly 16 million people in the United States have diabetes
and more than 625,000 new cases of diabetes are diagnosed each year. Diabetes
is a chronic disease characterized by the body's inability to maintain the
proper amount of circulating glucose. Glucose levels vary significantly
throughout the day, and the use of personal glucose monitors is a key factor in
the management of diabetes. According to Medical Data International, sales of
personal blood glucose monitoring products in the United States have increased
from approximately $450 million in 1991 to an estimated $730 million in 1995.
The Company estimates that the worldwide market for personal blood glucose
monitoring products was over $1.5 billion in 1995.
 
  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 DCCT
demonstrated, through a 1,400 patient trial over a nine-year period, that more
intensive treatment of people with Type I (insulin-dependent) diabetes can
reduce their risk of developing diabetes-related complications by approximately
60%. Despite the recommendation of the DCCT panel that people with Type I
diabetes follow an intensive therapy program, which includes testing glucose
levels at least four times a day, the majority of people with diabetes who use
insulin currently monitor their glucose level less than once per day. 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.
 
  The Company's proposed Lifeguide System is based on Company research
indicating that ISF glucose levels correlate closely with blood glucose levels.
The Company's proprietary method for ISF sampling involves a painless and
bloodless procedure that draws an ISF sample from the outermost layers of the
skin and captures that sample for measurement of glucose levels. The proposed
Lifeguide System will be comprised of the Lifeguide Monitor, a hand-held,
battery-powered monitor, and the Lifeguide Key, a single-use, disposable sample
collection device.
 
                                       3
<PAGE>
 
 
  The Company believes that its Lifeguide System will offer significant
advantages over commercially available personal blood glucose monitoring
systems and alternative non-invasive technologies under development, including:
 
  . Painless Procedure. By drawing ISF from only the outermost layers of the
    skin, the Lifeguide System avoids areas of high nerve density,
    eliminating the pain associated with conventional "finger-stick" sampling
    approaches.
 
  . Bloodless Approach. Utilizing the Company's proprietary ISF sampling
    technology, the Lifeguide System is designed to allow for the accurate
    measurement of glucose levels without drawing blood.
 
  . 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.
 
  . Ease of Use. The testing 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 (5 to 30 seconds) and waiting
    briefly for the 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 for
    commercially available personal glucose monitoring products.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves a high
degree of risk. In addition to the other information in this Prospectus, the
following risk factors should be considered carefully.
 
DEVELOPMENT OF NEW TECHNOLOGY; DEPENDENCE ON THE LIFEGUIDE SYSTEM; UNCERTAINTY
OF MARKET ACCEPTANCE
 
  The Company's future success is entirely dependent upon the successful
development, commercialization and market acceptance of the Lifeguide System,
the development of which is ongoing and the complete efficacy of which has not
yet been demonstrated. To date, the Company has only tested benchtop
prototypes of its proposed device, and the Company does not expect to produce
commercial prototypes of the Lifeguide Monitor and the Lifeguide Key until the
first quarter of 1997. There can be no assurance that unforeseen problems will
not occur in research and development, clinical testing, regulatory
submissions and approval, product manufacturing and commercial scale up,
marketing or product distribution. Any such occurrence could materially delay
the commercialization of the Lifeguide System or prevent its market
introduction entirely. Further, even if successfully developed, the commercial
success of the Lifeguide System will depend upon its acceptance as a painless,
bloodless, accurate, reliable and cost-effective alternative to existing blood
glucose monitoring techniques. The glucose monitoring industry is currently
dominated by several companies with established markets and distribution
channels. Because the proposed Lifeguide System will represent a new practice
in the monitoring of glucose levels, the Company is unable to predict how
quickly, if at all, its products will be accepted by members of the medical
community and people with diabetes. There is no assurance that the Company
will ever derive substantial revenues from the sale of the Lifeguide System.
See "Business."
 
HISTORY OF OPERATING LOSSES; ACCUMULATED DEFICIT; EXPECTATION OF FUTURE LOSSES
 
  The Company has generated no revenue and has sustained significant operating
losses each year since its inception. As of March 31, 1996, the Company had an
accumulated deficit of approximately $11,521,000. Net losses for the years
ended December 31, 1993, 1994 and 1995 were approximately $683,000, $2,492,000
and $5,049,000, respectively, and the Company expects such losses to continue
through 1999 and to increase at least through the end of 1998. The Company may
never generate substantial operating revenues or achieve profitability. The
Company's ability to generate revenues from operations and achieve
profitability is dependent upon successful development, regulatory approval
and commercialization of the Lifeguide System and the Company's successful
transition from a development stage company to a fully operating company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
 
LIMITED CLINICAL TESTING EXPERIENCE; UNCERTAINTY OF OBTAINING FDA CLEARANCES
 
  To date, testing of the Lifeguide System has been performed on benchtop
prototypes solely by Company personnel under controlled circumstances. The
Company expects to make commercial prototypes of the Lifeguide System
available to people with diabetes for self-testing in the first quarter of
1997 and to use the data derived from this testing to support a 510(k)
notification with the FDA to permit commercialization of the Lifeguide System
in the United States. 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 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 effective. There also
can be no assurance that a full Premarket Approval application (a "PMA") will
not be required. Approval of a PMA by the FDA would require substantial
clinical trials and other supplemental information regarding the proposed
Lifeguide System. If required, the preparation and filing of a PMA would
materially delay the introduction of the Lifeguide System. In addition, there
can be no assurance that the required FDA clearances or approvals will be
obtained on a timely basis or at all. The Company has no experience in
obtaining regulatory approval. See "--Government Regulation; Need for
Additional Government Clearances," "Business--Clinical Testing" and "--
Government Regulation."

HIGHLY COMPETITIVE MARKETS; RISK OF TECHNOLOGICAL OBSOLESCENCE
 
  The glucose monitoring industry is characterized by continuously evolving
technology and intense competition, and the market is currently dominated by
several companies with established products and distribution channels. In
addition, other companies are attempting to develop minimally- or non-invasive
glucose monitoring products competitive with the proposed Lifeguide System.
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
device obsolete or noncompetitive. In addition, numerous researchers are
investigating alternative treatments or cures for diabetes. If any of these
efforts are successful in reducing the complications associated with diabetes,
the need for the Company's products could be mitigated or become entirely
nonexistent. 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. Competition within
the glucose monitoring industry could also result in reductions of the prices
of the Company's products and the use of purchase incentive programs that
could adversely affect the Company's revenues and profitability. See
"Business--Competition."
 
LACK OF MANUFACTURING CAPABILITY; DEPENDENCE ON CONTRACT MANUFACTURERS AND
SUPPLIERS
 
  The Company's Lifeguide System is still in development and the Company has
not yet created or manufactured a commercial prototype of its device. To be
successful, the Company must manufacture the Lifeguide System in compliance
with regulatory requirements, in a timely manner and in sufficient quantities
while maintaining product quality and acceptable manufacturing costs. The
Lifeguide Monitor will be manufactured for the Company by an outside vendor
from primarily off-the-shelf components. The Lifeguide Key will be assembled
by the Company from components to be purchased from outside suppliers.
However, the Company presently has no manufacturing contracts or supply
agreements and has no manufacturing capability. In addition, one component of
the Lifeguide Monitor 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. 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.
Manufacturers often encounter difficulties in scaling up production of new
products, including problems involving production yields, quality control and
assurance, component supplies and shortages of personnel. 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 commercialization, nor that the Company will be able to assemble
and manufacture its products at an acceptable cost. See "Business--
Manufacturing."
 
DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY
 
  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. As of the date of this Prospectus, no patents have been issued to the
Company with respect to the Lifeguide System. The Company has applied for four
United States patents and for one corresponding PCT foreign patent covering
certain aspects of the technology underlying the Lifeguide System. There can
be no assurance, however, that any patents will be issued, that the scope of
any patent protection granted to the Company will prevent competitors from
introducing products competitive with the Lifeguide System 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 unpatented technologies
substantially equivalent to those of the Company. In addition, even if the
patents for which the Company has
 
                                       7
<PAGE>
 
applied are ultimately issued, other parties may hold or receive patents that
contain claims covering the Lifeguide System 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 as a result recently 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. See
"Business--Patents and Proprietary Rights."
 
GOVERNMENT REGULATION; NEED FOR ADDITIONAL GOVERNMENT CLEARANCES
 
  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
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.
 
  The Company has not obtained FDA clearance to market the Lifeguide System.
The regulatory process may delay the marketing of new products for lengthy
periods, impose substantial additional costs and provide an advantage to those
of the Company's competitors who have greater financial resources. FDA
marketing clearance regulations depend heavily on administrative
interpretation. There can be no assurance that interpretations made by the FDA
or other regulatory bodies, with possible retroactive effect, will not
adversely affect the Company. There can be no assurance that any such
clearance will be obtained in a timely manner, or at all. In addition, even if
obtained, FDA clearances 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 halted or adversely affected.
 
                                       8
<PAGE>
 
  The Company also plans to eventually distribute its products in several
foreign countries. The Company's products will be subject to a wide variety of
laws and regulations in these markets. Generally, the extent and complexity of
the regulation of medical devices is increasing worldwide, with regulations in
some countries already nearly as exhaustive as those applicable in the United
States. This trend may continue and the cost and time required to obtain
marketing approval in any given country may increase. There can be no
assurance that any foreign approvals will be allowed on a timely basis or at
all. See "--Limited Clinical Testing Experience; Uncertainty of Obtaining FDA
Clearances" and "Business--Government Regulation."
 
LACK OF COMMERCIAL SALES OR MARKETING EXPERIENCE
 
  The Company has no experience in marketing the Lifeguide System and has not
yet entered into any marketing or distribution arrangements for its proposed
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, if ever, or that its
sales and marketing efforts will be successful. See "Business--Sales and
Marketing."
 
DEPENDENCE ON KEY PERSONNEL; NEED FOR ADDITIONAL PERSONNEL
 
  The success of the Company is dependent in large part upon the ability of
the Company to attract and retain key management and operating personnel.
Qualified individuals are in high demand and are often subject to competing
offers. In the future, the Company will need to add additional skilled
personnel in the areas of research and development, sales, marketing and
manufacturing. There can be no assurance that the Company will be able to
attract and retain the qualified personnel needed for its business. The loss
of the services of one or more members of the Company's research,
manufacturing or management group or the inability to hire additional
personnel as needed would likely have a material adverse effect on the
Company's business and prospects. See "Business--Employees" and "Management."
 
FUTURE CAPITAL REQUIREMENTS; NO ASSURANCE FUTURE CAPITAL WILL BE AVAILABLE
 
  The proceeds of the Offering are expected to be sufficient to fund the
Company's operations for at least 24 months following the consummation of the
Offering. The Company may require substantial additional funds to meet its
working capital requirements for a full-scale commercial introduction of its
proposed Lifeguide System. In order to meet its needs beyond this 24-month
period, the Company may be required to raise additional funds through public
or private financings, including equity financings. Any additional equity
financings may be dilutive to purchasers in the Offering, and debt financing,
if available, may involve restrictive covenants. Adequate funds for the
Company's operations, whether from financial markets or from other sources,
may not be available when needed on terms attractive to the Company or at all.
Insufficient funds may require the Company to delay, scale back or eliminate
some or all of its programs designed to facilitate the commercial introduction
of the Lifeguide System or prevent such commercial introduction altogether.
See "Use of Proceeds" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
UNCERTAINTY OF THIRD PARTY REIMBURSEMENT
 
  Sales of the Company's proposed products in certain markets will be
dependent in part on availability of adequate reimbursement for personal
glucose monitoring products from third-party healthcare payors, such as
government and private insurance plans, health maintenance organizations and
preferred provider organizations. 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 its proposed Lifeguide System. Without
adequate support from third-party payors, the market for the Company's
Lifeguide System may be limited. See "Business--Third Party Reimbursement."
 
                                       9

PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE
 
  The Company faces an inherent business risk of exposure to product liability
claims in the event that an end-user is adversely affected by its prospective
products. The Company currently carries a product liability insurance policy
covering the Company's clinical testing with an aggregate limit of $1.0
million. There can be no assurance, however, that the Company will be able to
obtain product liability insurance coverage in connection with the
commercialization of the Lifeguide System on commercially reasonable terms, or
at all, or that such insurance, even if obtained, would adequately cover any
product liability claim. A product liability or other claim with respect to
uninsured liabilities or in excess of insured liabilities could have a
material adverse effect on the business and prospects of the Company. See
"Business--Product Liability."
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF PRICE
 
  Prior to the Offering there has been no public market for the Common Stock.
Accordingly, there can be no assurance that an active trading market will
develop or be sustained upon completion of the Offering or that the market
price of the Common Stock will not decline below the initial public offering
price. The initial public offering price of the Common Stock was determined by
negotiations between the Company and the Representatives of the Underwriters
and may not be indicative of the prices that will prevail in the public
market. The trading prices of the Company's Common Stock could be subject to
wide fluctuations in response to quarter to quarter variations in the
Company's operating results, announcements by the Company or its competitors
regarding the results of regulatory approval filings or clinical trials or
testing, developments or disputes concerning proprietary rights, technological
innovations or new commercial products, governmental regulatory action,
general conditions in the medical technology industry, or other events or
factors, many of which are beyond the Company's control. In addition, the
stock market has experienced extreme price and volume fluctuations, which have
particularly affected the market prices of many medical technology companies
and which have often been unrelated to the operating performance of such
companies. See "Underwriting."
 
CONTROL BY SIGNIFICANT SHAREHOLDERS; ANTITAKEOVER PROVISIONS APPLICABLE TO THE
COMPANY
 
  Upon completion of the Offering, the Company's directors and executive
officers beneficially will own in the aggregate approximately 6.0%, and
certain of the Company's other principal shareholders (which are affiliated
with certain of the Company's directors and executive officers) beneficially
will own in the aggregate approximately 35.9%, of the Company's outstanding
shares of Common Stock (including shares subject to outstanding options and
warrants). If these shareholders vote together as a group, they will be able
to substantially influence the business and affairs of the Company, including
the election of individuals to the Company's Board of Directors, and to
otherwise affect the outcome of certain actions that require shareholder
approval, including the adoption of amendments to the Company's articles of
incorporation, and certain mergers, sales of assets and other business
acquisitions or dispositions.
 
  Upon completion of the Offering, the Company will have authorized a class of
5,000,000 shares of undesignated preferred stock, $.01 par value, which may be
issued by the Company's Board of Directors on such terms, and with such
rights, preferences and designations, as the Company's Board of Directors may
determine. In addition, the Company's Amended Bylaws provide for a classified
Board of Directors elected to staggered terms. Finally, the Company is subject
to certain provisions of the Minnesota Business Corporation Act which limit
the voting rights of shares acquired in certain acquisitions and restrict
certain business combinations. Some or all of the foregoing factors could have
the effect of discouraging certain attempts to acquire the Company which could
deprive the Company's shareholders of opportunities to sell their shares of
Common Stock at prices higher than prevailing market prices. See "Description
of Capital Stock--Preferred Stock" and "--Provisions of the Company's Amended
Articles and Bylaws and the Minnesota Business Corporation Act."
 
RISK OF FUTURE SALES OF COMMON STOCK
 
  Sales of significant amounts of Common Stock in the public market or the
perception that such sales will occur could adversely affect the market price
of the Common Stock or the future ability of the Company to raise capital
through an offering of its equity securities. Of the 9,269,038 shares of
Common Stock to be outstanding upon completion of the Offering, the 3,000,000
shares offered hereby will be eligible for immediate sale in the
 
                                      10
<PAGE>
 
public market without restriction unless they are held by "affiliates" of the
Company within the meaning of Rule 144 of the Securities Act of 1933, as
amended (the "Securities Act"). The remaining 6,269,038 shares of Common Stock
held by existing shareholders upon completion of the Offering will be
"restricted securities" as that term is defined in Rule 144 under the
Securities Act. The Company, its directors, officers and certain of its
shareholders (representing 6,126,035 of such restricted shares) have agreed
that they will not sell, directly or indirectly, any Common Stock without the
prior consent of Piper Jaffray Inc. for a period of 180 days from the date of
this Prospectus. Beginning on the 181st day after the date of this Prospectus,
when agreements not to sell such shares expire, approximately 716,239 of the
restricted shares will become eligible for immediate sale, subject to
compliance with the volume limitations and other restrictions of Rule 144, and
approximately 1,413,045 of the restricted shares may become eligible for
immediate sale without restriction pursuant to Rule 144(k). In addition,
certain shareholders and warrantholders, representing approximately 6,250,621
shares of Common Stock, have the right, subject to certain conditions, to
include their shares in future registration statements relating to the
Company's securities and to cause the Company to register certain shares of
Common Stock owned by them. See "Shares Eligible for Future Sale" and
"Underwriting."
 
NO DIVIDENDS
 
  The Company has never paid or declared a dividend on its capital stock and
does not anticipate doing so for the foreseeable future. See "Dividend
Policy."
 
SUBSTANTIAL DILUTION TO PURCHASERS IN THE OFFERING
 
  Purchasers of the shares offered hereby will experience an immediate,
substantial dilution in net tangible book value per share of Common Stock. See
"Dilution."
 
                                      11
<PAGE>
 
                                USE OF PROCEEDS
 
  The net cash proceeds to the Company from the sale of the Common Stock
offered hereby are estimated to be approximately $26,105,000 ($30,080,750 if
the Underwriters' over-allotment option is exercised in full), after deducting
the underwriting discount and estimated expenses of the Offering.
 
  The Company anticipates that the net proceeds, including interest earned
thereon, will be used to fund the following: approximately $9 million for
continued development and testing of and clinical trials for the Lifeguide
System; approximately $5 million for capital expenditures, primarily the
development and construction of an initial and a full-scale commercial
manufacturing and assembly line; approximately $10 million for research and
development, manufacturing and marketing activities; and the balance for
working capital and other general corporate purposes. The amounts actually
expended for these purposes will depend upon numerous factors, including the
results of clinical studies, the design and cost of the Company's initial
manufacturing facility, the status of competitive products and other factors.
Pending the use of the net proceeds of the Offering, the Company will invest
the funds in short-term, interest-bearing, investment grade securities. The
Company expects that the proceeds of the Offering, together with cash on hand
and interest expected to be earned thereon, will be sufficient to fund its
operations for at least 24 months following the consummation of the Offering.
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its capital
stock since its inception. The Company currently intends to invest any
earnings in the development and expansion of its business and does not intend
to pay dividends in the foreseeable future. The payment of dividends, if any,
in the future will be at the discretion of the Board of Directors and will
depend on the Company's earnings, financial condition, capital requirements
and other relevant factors.

                                   DILUTION
 
  Pro forma net tangible book value per share represents total assets, less
intangible assets and total liabilities, divided by the number of shares
outstanding as of March 31, 1996 (assuming the conversion into Common Stock of
all of the Company's outstanding shares of Preferred Stock). The Company's pro
forma net tangible book value at March 31, 1996 was $14,692,253 or
approximately $2.34 per share. Without taking into account any changes in such
net tangible book value per share after March 31, 1996, other than to give
effect to the sale of the shares of Common Stock offered hereby and the
receipt of the net proceeds of such sale, the pro forma net tangible book
value per share at March 31, 1996 would have been $40,797,253 or $4.40 per
share. This represents an immediate increase in net tangible book value per
share of $2.06 to existing shareholders and an immediate dilution of $5.10 per
share to new investors. The following table sets forth this per share
dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Financial
Statements and the Notes thereto included elsewhere in this Prospectus. This
Prospectus contains, in addition to historical information, forward-looking
statements that involve risks and uncertainties. The Company's actual results
could differ materially from the results discussed in the forward-looking
statements. Factors that could cause or contribute to such differences include
those discussed below, as well as those discussed elsewhere in this
Prospectus. See "Risk Factors."
 
GENERAL
 
  Integ, a development stage company incorporated on April 3, 1990, is engaged
in the development of the Lifeguide System, a painless and bloodless hand-held
glucose monitoring product for use by people with diabetes. Utilizing the
Company's proprietary 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.
 
  From inception through March 31, 1996, the Company has incurred losses
totaling $11,521,395, consisting of $6,203,455 of research and development
expenses, $3,575,589 of general and administrative expenses and $1,742,351 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 the first half
of 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.
 
RESULTS OF OPERATIONS
 
 COMPARISON OF THREE MONTHS ENDED MARCH 31, 1996 AND 1995
 
  General. Net losses increased to $1,730,870 during the three months ended
March 31, 1996 from $957,277 during the same period in 1995. The Company
expects net losses to continue to escalate during the remainder of 1996 and
during 1997 and 1998 because of anticipated spending increases necessary to
complete the design of the Company's product, expenses resulting from
manufacturing development and clinical testing, marketing and advertising
expenses related to market introduction, and expenses required to establish
and maintain the Company's sales force.
 
  Research and development expenses. Research and development expenses
increased to $768,488 during the three months ended March 31, 1996 from
$460,185 during the same period in 1995. The increase in research and
development expenses was due primarily to increases in compensation, benefit
and employee recruiting costs and, to a lesser extent, increases in consulting
expenses, patent legal fees and the cost of prototype materials purchased.
 
  General and administrative expenses. General and administrative expenses
increased to $501,963 during the three months ended March 31, 1996 from
$272,780 during the same period in 1995. The increase in general and
administrative expenses was due to increases in compensation, facility costs
and depreciation of furniture and equipment.
 
  Clinical and regulatory expenses. Clinical and regulatory expenses increased
to $122,856 during the three months ended March 31, 1996 from $61,104 during
the same period in 1995. The increase was 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 for the
Lifeguide System.
 
  Manufacturing development expenses. Manufacturing development expenses
increased to $307,885 during the three months ended March 31, 1996 from
$48,877 during the same period in 1995. The increase was due primarily to
increases in pre-manufacturing expenses, consisting of compensation and
recruiting costs and
 
                                      16
<PAGE>
 
consulting expenses incurred to plan and design the Company's automated
manufacturing processes. These manufacturing related costs will be allocated
to inventory and cost of goods sold once production of the Lifeguide System
commences.
 
  Sales and marketing expenses. Sales and marketing expenses increased to
$189,321 during the three months ended March 31, 1996 from $87,154 during the
same period in 1995. The increase was due primarily to compensation and
recruiting costs, product design costs and expenses related to building a
sales and marketing organization.
 
  Interest income. Interest income increased to $181,849 during the three
months ended March 31, 1996 from $27,062 during the same period in 1995. The
increase was due primarily to the investment in government securities of
proceeds received from the sale of a series of the Company's Preferred Stock
in June 1995. See Note 4 of Notes to Financial Statements.
 
 COMPARISON OF YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
  General. Net losses increased to $5,048,730 during 1995 from $2,492,220
during 1994 and $682,725 during 1993.
 
  Research and development expenses. Research and development expenses
increased to $2,462,868 during 1995 from $1,568,220 during 1994 and $441,964
during 1993. The increases in research and development expenses were due
primarily to increases in compensation, benefit and employee recruiting costs
and, to a lesser extent, from increases in consulting expenses, patent legal
fees and the cost of prototype materials purchased.
 
  General and administrative expenses. General and administrative expenses
increased to $1,417,365 during 1995 from $792,017 during 1994 and $237,177
during 1993. The increases in general and administrative expenses were due to
increases in compensation, facility costs and depreciation of furniture and
equipment.
 
  Clinical and regulatory expenses. Clinical and regulatory expenses increased
to $297,580 during 1995 from $52,083 during 1994. No clinical and regulatory
expenses were recorded in 1993. 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 $718,316 during 1995 from $55,430 during 1994. No manufacturing
development expenses were recorded in 1993. 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
$384,722 during 1995 from $54,409 during 1994. No sales and marketing expenses
were recorded in 1993. The increases were due primarily to compensation and
recruiting costs, product design costs and expenses related to building a
sales and marketing organization.
 
  Interest income. Interest income increased to $580,840 during 1995 from
$45,112 during 1994 and $4,244 during 1993. The increases were due primarily
to the investment in government securities of the proceeds from the sale of
the Company's Preferred Stock. See Note 4 of Notes to Financial Statements.
 
                                      17

LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's operations since inception have been funded by net proceeds
from the sale of Preferred Stock totaling $25,689,732. As of March 31, 1996,
the Company had cash and cash equivalents of $14,561,032 and working capital
of $14,196,596.
 
  On March 27, 1996, the Company executed an equipment loan agreement with a
venture leasing company which provides for borrowings of up to $5,000,000
under a line of credit. The lender has committed to a total line of
$12,500,000 by July 31, 1996 to finance the purchase of furniture and
equipment, including automated manufacturing equipment and tooling. The line
of credit expires December 31, 1998, and approximately $930,000 was borrowed
under the line on March 29, 1996. In consideration of the line of credit, the
Company has agreed to issue warrants for the purchase of Common Stock equal to
8.8% of the dollar value of the borrowings outstanding under such agreement,
as borrowed, or for any unfunded portion of this commitment, if any exists at
December 31, 1998. Each warrant is exercisable initially at $6.00 per share,
or subsequently at 80% of the purchase price per share of a subsequent
financing if such occurs prior to a subsequent funding.
 
  Management expects that the Company's existing cash balance and borrowings
available under the loan agreement discussed above, along with the anticipated
net proceeds of the Offering, will be sufficient to fund the operations of the
Company through at least the next 24 months. 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 of
regulatory actions regarding the Lifeguide System, the costs and timing of
expansion of sales, marketing and manufacturing activities, results of
clinical trials and competition. There can be no assurance that the Company
will not be required to raise additional capital during the next 24 months or
thereafter or that such capital will be available on acceptable terms, or at
all. See "Risk Factors--Future Capital Requirements; No Assurance Future
Capital Will Be Available."

  The Company is engaged in the development of the Lifeguide System, a
painless and bloodless glucose monitoring product for use by people with
diabetes. The Company believes the proposed Lifeguide System will be the first
hand-held glucose monitor that allows people with diabetes to frequently self-
monitor their glucose levels without repeatedly lancing their fingers to
obtain a blood sample. The Lifeguide System utilizes the Company's proprietary
ISF sampling technology. The Company believes that its system will represent a
significant technological advance in glucose monitoring that will enable
people with diabetes to manage their disease more effectively and
conveniently.
 
INDUSTRY OVERVIEW
 
 DIABETES
 
  It is estimated that there are as many as 100 million people with diabetes
worldwide. In the United States, diabetes is a leading cause of blindness,
kidney failure, amputation and heart failure, and is the fourth leading cause
of death by disease. Diabetes is a chronic disease affecting overall health
which can lead to severe complications and requires active disease management
on a daily basis. Nearly 16 million people in the United States have diabetes,
and more than 625,000 new cases of diabetes are diagnosed each year. According
to the American Diabetes Association, the total estimated cost of diabetes in
the United States exceeds $90 billion per year.
 
  Diabetes is a disease characterized by the body's inability to maintain the
proper amount of circulating glucose. Glucose is derived from the
carbohydrates in food and circulates through the bloodstream to the cells of
the body, where it is converted into energy. The concentration of circulating
glucose must be maintained within a relatively narrow range to maintain normal
health. Insulin, a hormone secreted by the pancreas, is the primary regulatory
mechanism by which the body reduces glucose levels. Diabetes is caused by a
reduction in the number of insulin producing cells, defects in those cells, a
resistance to circulating insulin or various combinations of these factors.
Due to the reduced ability to control circulating glucose levels, people with
diabetes are subject to significant complications affecting their overall
health and life expectancy. High glucose levels result in fatigue, slow
healing and low resistance to infection and, over time, can lead to
retinopathy (eye disease), nephropathy (kidney disease), neuropathy (nerve
disease), cardiovascular complications (heart and blood vessel disease) and
podiatric (foot) complications. Low glucose levels can result in faintness,
weakness and, in severe cases, unconsciousness and death.
 
  The American Diabetes Association estimates that Type I (insulin-dependent
or juvenile onset) diabetes, a form of the disease requiring daily insulin
treatments, comprises approximately 5-10% of diagnosed diabetes cases in the
United States. The other 90-95% of diagnosed diabetes cases in the United
States are comprised of Type II (non-insulin-dependent or adult onset)
diabetes. Type II diabetes is usually managed by oral drug therapy, diet and
exercise but requires treatment with insulin in approximately 35% of all cases
of this type.
 
 GLUCOSE MONITORING
 
  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.
 
  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. According
to Medical Data International, sales of personal blood glucose monitoring
products in the United States have increased from approximately
 
                                      19
<PAGE>
 
$450 million in 1991 to an estimated $730 million in 1995. The Company
estimates that the worldwide market for personal glucose monitoring products
was over $1.5 billion in 1995.
 
  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
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 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 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 retail
prices of these systems range from approximately $30 to $130 per meter and
from approximately $0.47 to $0.82 per test strip, although, due to rebates and
trade-ins, test meters are often offered to people with diabetes at
substantially reduced prices in expectation of recurring purchases of test
strips.
 
  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 either non-invasive near-infrared
spectroscopic or reverse iontophoretic 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
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.
 
                                      20
<PAGE>
 
  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. No glucose monitor using either non-invasive
near-infrared spectroscopic or reverse iontophoretic technologies or any other
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 in a painless and
bloodless manner and then measures the glucose level in that sample in a
compact, easy-to-use device. The proposed Lifeguide System will be comprised
of the Lifeguide Monitor, a hand-held, battery-powered monitor, and the
Lifeguide Key, a single-use, disposable sample collection 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 1/100th of
a drop) is analyzed for glucose levels by the Lifeguide Monitor 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 Monitor 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 the ISF sample absorbs part of the
energy in a manner that is detected, measured and displayed by the Lifeguide
Monitor.
 
  The Company believes that its approach has significant technological
advantages over non-invasive near-infrared spectroscopic and reverse
iontophoretic technologies. Because the Lifeguide System obtains a physiologic
sample of ISF for testing, the accurate and precise analysis of glucose in the
sample is a straight-forward process. In addition, because the Lifeguide
System removes the ISF from the body for testing, the sample can be accurately
analyzed using well established spectroscopic techniques in the far-infrared
waveband region, the region which produces the strongest signal for measuring
glucose. In infrared spectroscopy, infrared light energy is transmitted
through (or reflected off) a sample containing an analyte (such as glucose),
and the resulting signal is then measured. Because many analytes have
recognizable infrared energy absorption characteristics, measurement of the
resulting signal indicates the amount of the analyte present in the sample.
Each analyte has one waveband region in the infrared spectrum which it absorbs
most strongly. For glucose, the
 
                                      21
<PAGE>
 
far-infrared waveband region is the primary absorbing region, and therefore
gives the strongest signal for measurement. Non-invasive near-infrared
spectroscopy technology cannot use this far-infrared waveband because this
waveband is also strongly absorbed by the water prevalent in body tissue.
 
 POTENTIAL ADVANTAGES OF THE LIFEGUIDE SYSTEM
 
  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:
 
  . Painless Procedure--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.
 
  . 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 Monitor. 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 (5 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 meters and
    disposable test strips.
 
  Because of these potential advantages, the Company believes that the
proposed Lifeguide System may facilitate greater compliance with the
recommendations of the DCCT panel.

THE LIFEGUIDE SYSTEM
 
  The proposed Lifeguide System will be comprised of (i) the Lifeguide
Monitor, a hand-held, battery-powered monitor, and (ii) the Lifeguide Key, a
single-use, disposable sample collection device.
 
[Line drawing of (i) the Lifeguide Monitor with captions for (and arrows 
pointing to corresponding parts of the Lifeguide Monitor): "LCD Readout" (with 
readout of 114 mg/dl), "Function Buttons," "Release Button for Lifeguide Key," 
"Lifeguide Key" and "Port for Lifeguide Key"; and (ii) the Lifeguide Key, with 
captions for (and arrows pointing to corresponding parts of the Lifeguide Key):
"Sample Window," "Handle" and "Needle."]

  The Lifeguide Monitor will be an integrated, compact, easy-to-use glucose
monitoring device similar in size to a hand-held cellular telephone. The
Lifeguide Monitor 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 Monitor
will have visual and audible prompts to assist the user through the sampling
process. The Lifeguide Monitor will have the ability to indicate when an
appropriate sample has been obtained and to self-diagnose any electronic
malfunction. In addition, the Lifeguide Monitor will be capable of
transferring 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 Monitor. The proprietary design of
the Lifeguide Key will allow for the painless capture of the required ISF
sample and the retention of the sample during the measurement and disposal
process. The Lifeguide Key will use a very small needle used to draw a sub-
microliter sample across a specially designed window through which a sample
can be read. The Lifeguide Key will be similar in size to an average house
key. Each Lifeguide Key will be packaged in a sterile pouch along with a
protective cap that will serve as a means for disposal after use.
 
  To operate the Lifeguide System, the user will insert the Lifeguide Key into
the Lifeguide Monitor and hold the Lifeguide System against the skin until the
Lifeguide Monitor indicates the sampling process is complete. The sampling
time will vary from 5 to 30 seconds depending on the user and the location of
sampling. Shortly 
 
                                      23
<PAGE>
 
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 Monitor, there will be no need
to clean the Lifeguide Monitor 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.
 
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 $6.2 million in research and development expenses. The Company
believes that it is in the final stages of its product development and expects
to have final design specifications for its first commercial Lifeguide System
by the end of 1996. 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 recently 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 demonstrate the accuracy of the Lifeguide System when testing
samples containing known glucose values. The Company expects to complete
development of a fully-integrated commercial prototype of the Lifeguide
System, including a hand-held, battery-powered Lifeguide Monitor and a single-
use, disposable Lifeguide Key, each expected to closely resemble the first
commercial version, in the first quarter of 1997.
 
  The Company's success will be dependent upon its ability to 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
Monitor development effort is to integrate the current benchtop components
into a hand-held, battery-powered final product that can be reliably and cost-
effectively manufactured. The development focus with respect to the Lifeguide
Key is on identifying the critical factors and specifications that will ensure
that functional, highly reliable samplers can be produced in high volumes at
the lowest unit cost. Both the Lifeguide Monitor and the Lifeguide Key are
being designed to use materials and components that can be easily produced by
suppliers with a minimum of customization. See "--Manufacturing."
 
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 in benchtop prototypes for
accuracy and precision. To date, testing of the Lifeguide System has been
performed on benchtop prototypes solely by Company personnel under controlled
circumstances. All ISF samples used in this testing have been obtained
utilizing the Company's proprietary sampling method.
 
  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 to the glucose levels in blood when the
glucose levels are in a relatively steady state. This study compared the ISF
and blood glucose
 
                                      24
<PAGE>
 
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, which is ongoing, is being conducted to provide
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. To date, this study has
compared the ISF and blood glucose values in six individuals with Type I
diabetes over a five-hour period of rising and falling glucose values.
Cumulative data from these six subjects has also yielded a correlation
coefficient of 0.96.
 
  In 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 (on a 0.0 to 1.0 scale, with 1.0 representing
a perfect correlation).
 
  The Company plans to use commercial prototypes of the Lifeguide System
(expected to be available in the first quarter of 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 the first half of 1997.
 
  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. See "Risk Factors--Limited Clinical Testing Experience; Uncertainty
of Obtaining FDA Clearances."
 
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 Monitor. This manufacturer will be used to build all prototypes
of the Lifeguide Monitor for testing and to develop test methods and equipment
for the Company. Most of the components in the Lifeguide Monitor 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 Monitor 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 manufacturing
line prior to installation of any full-scale commercial 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 greatly expanded manufacturing capability.
 
                                      25
<PAGE>
 
  The Company presently has no manufacturing contracts or supply agreements
and has no manufacturing capability. 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. See "Risk Factors--Lack of
Manufacturing Capability; Dependence on Contract Manufacturers and Suppliers."
 
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.
 
  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 and
video 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 early
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 people with diabetes. In addition, during this phase the
Company expects to market to selected managed care organizations in
anticipation of full availability of product for contracted utilization. The
primary purposes of the limited introduction phase are to allow the Company to
build manufacturing capability in a controlled fashion prior to full product
commercialization and 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
specialized sales group will target the retail distribution channel. A third
group will promote the Company's products to healthcare professionals and
organizations that influence patient choices.
 
  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. See "Risk Factors--Lack of Commercial
Sales or Marketing Experience."

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 filed
four patent applications in the United States directed towards various aspects
of the technology underlying the Lifeguide System and has received notice of
allowance from the United States Patent and Trademark Office (stating that the
application has been examined and is allowed for issuance as a patent and
requiring payment of a fee within a specified period) of one of these
applications relating to the method of drawing an ISF sample from the outer
layers of the skin for subsequent glucose analysis. The Company has also filed
one corresponding PCT foreign patent application 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.
 
  No assurance can be given that any 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 as a result recently 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. See
"--Legal Proceedings" and "Risk Factors--Dependence on Patents and Proprietary
Technology."
 
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
 
                                      27
<PAGE>
 
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 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. See "Risk Factors--
Uncertainty of Third Party Reimbursement."
 
COMPETITION
 
  The Company believes that its success will depend primarily upon its ability
to create and deliver a painless and bloodless glucose monitoring system on a
timely basis and at a competitive price, 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. (which has agreed to be purchased by
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 Monitor 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
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
 
                                      28
<PAGE>
 
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. See "Risk Factors--
Highly Competitive Markets; Risk of Technological Obsolescence" and
"Business--Existing Personal Blood Glucose Monitoring Systems and Alternative
Technologies."
 
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
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 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.
 
  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
 
                                      29
<PAGE>
 
issued. Requirements pertaining to the Lifeguide System will vary widely from
country to country, and involve anything from simple product registrations to
detailed submissions similar to those required by the FDA. See "Risk Factors--
Limited Clinical Testing Experience; Uncertainty of Obtaining FDA Clearances"
and "--Government Regulation; Need for Additional Government Clearances."
 
EMPLOYEES
 
  As of May 17, 1996, the Company had a total of 52 full-time employees. The
Company also had consulting or other contract arrangements with 18 persons on
a full- or part-time basis. Of this total workforce, 31 persons were engaged
in research and development activities, 14 persons in manufacturing
development, two persons in sales and marketing, 14 persons in clinical,
regulatory and quality functions and 9 persons in support and administrative
functions. It is anticipated that the Company will add approximately 25
employees by the end of 1996, primarily in the areas of manufacturing and
manufacturing engineering.
 
FACILITIES
 
  The Company currently leases approximately 42,000 square feet of space at
2800 Patton Road, St. Paul, Minnesota. The lease expires on September 30,
2000. The Company believes its facilities will be adequate for its needs
through the full commercial introduction of the Lifeguide System.
 
PRODUCT LIABILITY
 
  The Company currently carries a product liability insurance policy covering
the Company's clinical testing with an aggregate limit of $1.0 million.
Although the Company expects to obtain product liability insurance coverage in
connection with the commercialization of the Lifeguide System, there can be no
assurance that such insurance will be available on commercially reasonable
terms, or at all, or that such insurance, even if obtained, would adequately
cover any product liability claim. A product liability or other claim with
respect to uninsured liabilities or in excess of insured liabilities could
have a material adverse effect on the business and prospects of the Company.
See "Risk Factors--Product Liability Risk; Limited Insurance Coverage."
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any legal proceedings.

COMMITTEES

Committee and a Nominating Committee. The Compensation Committee makes

"1991 Stock Option Plan"), the 1994 Long-Term Incentive and Stock Option Plan
(as amended, the "1994 Stock Option Plan" and together with the 1990 and 1991
Stock Option Plans, the "Stock Option Plans") and the Company's 1996
Directors' Stock Option Plan (the "Directors' Plan"). The Compensation
Committee has delegated authority to the Chief Executive Officer to grant
options in such officer's discretion to employees who are not executive
officers in amounts not exceeding an aggregate of 10,000 shares of Common
Stock per individual in any period of 12 consecutive months pursuant to the
Stock Option Plans.
 
  The Audit Committee reviews the results and scope of the audit and other
services provided by the Company's independent auditors, as well as the
Company's accounting principles and its system of internal controls, and
reports the results of its review to the full Board of Directors and to
management.
 
  The Nominating Committee makes recommendations regarding director and
officer nominations.
 
DIRECTORS' COMPENSATION
 
  Prior to the Offering, directors of the Company received no compensation for
their services to the Company as such. Upon closing of the Offering, directors
who are not employees of the Company will receive payments of $3,000 per
quarter, $1,000 per meeting attended in person ($500 if attended by telephone)
and $500 per committee meeting attended, up to a maximum of $20,000 per year,

attending meetings of the Board of Directors and its committees. Upon closing
of the Offering, directors who are not employees of the Company will be
granted options to purchase Common Stock under the Directors' Plan. See "--
Stock Plans."
 
LIMITATION OF LIABILITY
 
  The Company's Amended and Restated Articles of Incorporation limit the
liability of directors in their capacity as directors to the full extent
permitted by Minnesota law. As permitted by Minnesota law, the Company's
Amended and Restated Articles of Incorporation provide that a director shall
not be liable to the Company or its shareholders for monetary damages for
breach of fiduciary duty as a director, except (i) for any breach of the
director's duty of loyalty to the Company or its shareholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for dividends, stock repurchases and other
distributions made in violation of Minnesota law or for violations of the
Minnesota securities laws, (iv) for any transaction from which the director
derived an improper personal benefit or (v) for any act or
 
                                      33
<PAGE>
 
omission occurring prior to the effective date of the provision in the
Company's Amended and Restated Articles of Incorporation limiting such
liability. These provisions do not affect the availability of equitable
remedies, such as an action to enjoin or rescind a transaction involving a
breach of fiduciary duty, although, as a practical matter, equitable relief
may not be available. The above provisions also do not limit liability of the
directors for violations of, or relieve them from the necessity of complying
with, the federal securities law.

   on the anniversary dates of such grants for each of the four years
   following such grant. The option granted to Ms. Critzer for 66,666 shares
   of Common Stock becomes exercisable with respect to 25% of the shares on
   the date of grant and 25% of the shares on the anniversary of such date for
   each of the three years thereafter. To the extent not already exercisable,
   the options generally become exercisable in the event of a merger in which
   the Company is not the surviving corporation, a transfer of all of the
   Company's stock, a sale of substantially all of the Company's assets or a
   dissolution or liquidation of the Company.
(2) In 1995, the Company granted employees options to purchase an aggregate of
    355,971 shares of Common Stock.
(3) The exercise price may be paid in cash, in shares of Common Stock with a
    market value as of the date of exercise equal to the option price or a
    combination of cash and shares of Common Stock.
(4) The compounding assumes a ten-year exercise period for all option grants.
    The 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the Securities and Exchange Commission and do not
    represent the Company's estimate or projection of the Company's future
    Common Stock prices. These amounts represent certain assumed rates of
    appreciation only. Actual gains, if any, on stock option exercises are
    dependent on the future performance of the Common Stock and overall stock
    market conditions. The amounts reflected in this table may not necessarily
    be achieved.
 
  In November 1995, Mr. Harding received options to purchase 66,666 shares of
Common Stock under the 1994 Stock Option Plan. These options are exercisable
at $1.20 per share, expire on October 31, 2005 and become exercisable with
respect to 25% of the shares in November 1995 and 25% of the shares on the
anniversary of such date for each of the three years thereafter.
 
  In April 1996, Ms. Breslawec received options to purchase 33,333 shares of

STOCK PLANS
 
  Stock Option Plans. Pursuant to the Stock Option Plans, executive officers,
other employees and consultants of the Company may receive options to purchase
Common Stock. The Stock Option Plans provide for the grant of both incentive
stock options intended to qualify for preferential tax treatment under Section
422 of the Internal Revenue Code of 1986, as amended, and nonqualified stock
options that do not qualify for such treatment. The exercise price of all
incentive stock options granted under the Stock Option Plans must equal or
exceed the fair market value of the Common Stock at the time of grant. The
Stock Option Plans also provide for grants of stock appreciation rights,
restricted stock awards and performance awards. Only employees are eligible
for the grant of incentive stock options. The Stock Option Plans are
administered by the Compensation Committee, which has delegated authority to
the Chief Executive Officer to grant options to employees who are not
executive officers in amounts not exceeding an aggregate of 10,000 shares of
Common Stock per individual in any period of 12 consecutive months.
 
  A total of 1,913,333 shares of Common Stock have been reserved for issuance
under the Stock Option Plans. As of May 1, 1996, the Company had outstanding
options to purchase an aggregate of (i) 927,109 shares, at a weighted average
exercise price of $3.58 per share, pursuant to the Stock Option Plans
(excluding the restricted stock grant to Mr. Solomon) and (ii) 42,993 shares,
at an exercise price of $.84 per share, granted outside of the Stock Option
Plans.
 
  Directors' Plan. The Directors' Plan provides for an automatic grant of
nonqualified stock options to purchase 15,000 shares of Common Stock to
directors who are not employees of the Company on the later of the closing of
the Offering or the date such individuals become directors of the Company, and
an option to purchase 5,000 shares of Common Stock on each subsequent annual
shareholder meeting date, subject to certain limitations. Options granted on
the closing date of the Offering or on the date an individual becomes a
director of the Company shall vest and thereby become exercisable as to 50% of
such shares on the anniversary of the date of such grant and 25% at the
anniversary date for each of the two years thereafter if the holder remains a
director on such dates. Options granted on the date of each annual meeting of
shareholders become exercisable six months subsequent to the date of grant.
The Company has reserved 300,000 shares of Common Stock for issuance under the
Directors' Plan. The option price for directors is equal to the fair market
value of a share of Common Stock as of the date of grant. Pursuant to the
Directors' Plan, Drs. Knudson and Sembrowich and Messrs. Bennett, Maudlin,
McGuire, Momsen and Nickoloff each will receive options to purchase 15,000
shares of Common Stock, which options will be exercisable at the initial
public offering price. Pursuant to the partnership agreement for MIP, Messrs.
Maudlin and Nickoloff will assign to MIP all of the options granted to them
under the Directors' Plan. No other options have been granted under the
Directors' Plan.

  Upon completion of the Offering, the total number of shares of all classes
of stock which the Company has authority to issue will be 20,000,000 shares of
Common Stock, $.01 par value, and 5,000,000 shares of undesignated preferred
stock, $.01 par value. As of May 1, 1996, there were 6,269,038 shares of
Common Stock outstanding (assuming conversion into Common Stock of all
outstanding shares of Preferred Stock), which were held of record by 67
shareholders, and no shares of undesignated preferred stock outstanding.
 
COMMON STOCK
 
  The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of shareholders. There is no
cumulative voting for the election of directors so that the holders of more
than 50% of the outstanding Common Stock can elect all directors. Subject to
preferences that may be applicable to any outstanding preferred stock, holders
of Common Stock are entitled to receive ratably such dividends as may be
declared by the Board of Directors of the Company out of funds legally
available therefor and in liquidation proceedings. Holders of Common Stock
have no preemptive or subscription rights and there are no redemption rights
with respect to such shares. The outstanding shares of Common Stock are, and
the shares of Common Stock offered hereby will be, fully paid and
nonassessable.
 
PREFERRED STOCK
 
  The Company's Board of Directors is authorized, without further shareholder
action, to issue preferred stock in one or more series and to fix the voting
rights, liquidation preferences, dividend rights, repurchase rights,
conversion rights, redemption rights and terms, including sinking fund
provisions, and certain other rights and preferences, of the preferred stock.
 
  Although there is no current intention to do so, the Board of Directors of
the Company may, without shareholder approval, issue shares of a class or
series of preferred stock with voting and conversion rights which could
adversely affect the voting power or dividend rights of the holders of Common
Stock and may have the effect of delaying, deferring or preventing a change in
control of the Company.
 
WARRANTS AND OPTIONS
 
  The Company has issued warrants to purchase its Common Stock from time to
time in connection with certain financing arrangements. Warrants to purchase a
total of 339,745 shares of Common Stock have been issued by the Company at a
weighted average exercise price of $4.86 per share in connection with certain
equity financing transactions. Such warrants are all currently exercisable and
expire on dates ranging from November 1997 to January 2005. Warrants to
purchase a total of 119,614 shares of Common Stock have been issued by the
Company at a weighted average exercise price of $4.13 per share in connection
with certain equipment lease financing arrangements. Such warrants are all
currently exercisable and expire during the period from December 1999 through
June 2005. All outstanding warrant agreements provide for antidilution
adjustments in the event of certain mergers, consolidations, reorganizations,
recapitalizations, stock dividends, stock splits or other changes in the
corporate structure of the Company. Holders of warrants to purchase
approximately 406,028 shares of Common Stock will be entitled to certain
rights to cause the Company to register the sale of such shares under the
Securities Act. See "Shares Eligible for Future Sale."

  As of May 1, 1996, the Company had issued options to purchase a total of
970,102 shares of Common Stock. Of this amount, options to purchase 927,109
shares of Common Stock had been issued pursuant to the Company's Stock Option
Plans at a weighted average exercise price of $3.58 per share, and options to
purchase 42,993 shares of Common Stock had been issued outside of the Stock
Option Plans at an exercise price of $0.84 per share. Options under the Stock
Option Plans are granted by the Compensation Committee, which has delegated
authority to the Chief Executive Officer to grant options to employees who are
not executive officers in amounts not exceeding an aggregate of 10,000 shares
of Common Stock per individual in any period of 12 consecutive months. The
Compensation Committee may issue options with varying vesting schedules, but
all options granted pursuant to the Stock Option Plans must be exercised
within ten years from the date of grant. The Company has also granted options
to purchase 105,000 shares of Common Stock to directors who are not employees
upon the closing of the Offering pursuant to the Company's Directors' Plan at
an exercise price per share equal to the initial public offering price. See
"Management--Stock Plans." All options granted under the Stock Option Plans or
the Directors' Plan provide for antidilution adjustments in the event of
certain mergers, consolidations, reorganizations, recapitalizations, stock
dividends, stock splits or other changes in the corporate structure of the
Company.
 
PROVISIONS OF THE COMPANY'S AMENDED ARTICLES AND BYLAWS AND THE MINNESOTA
BUSINESS CORPORATION ACT
 
  The existence of authorized but unissued preferred stock, described above,
and certain provisions of the Company's Amended and Restated Articles of
Incorporation and Amended Bylaws and Minnesota law, described below, could
have an antitakeover effect. These provisions are intended to provide
management flexibility, to enhance the likelihood of continuity and stability
in the composition of the Company's Board of Directors and in the policies
formulated by the Board of Directors and to discourage an unsolicited takeover
of the Company if the Board of Directors determines that such a takeover is
not in the best interests of the Company and its shareholders. However, these
provisions could have the effect of discouraging certain attempts to acquire
the Company which could deprive the Company's shareholders of opportunities to
sell their shares of Common Stock at prices higher than prevailing market
prices.
 
  Pursuant to the Amended Bylaws, the Board of Directors of the Company is
divided into three classes serving staggered three-year terms. As a result, at
least two shareholders' meetings will generally be required for shareholders
to effect a change in control of the Board of Directors.
 
  Section 302A.671 of the Minnesota Business Corporation Act (the "MBCA")
applies, with certain exceptions, to any acquisition of voting stock of the
Company (from a person other than the Company, and other than in connection
with certain mergers and exchanges to which the Company is a party) resulting
in the beneficial ownership of 20% or more of the voting stock then
outstanding. Section 302A.671 requires approval of any such acquisitions by a
majority vote of the shareholders of the Company prior to its consummation. In
general, shares acquired in the absence of such approval are denied voting
rights and are redeemable at their then fair market value by the Company
within 30 days after the acquiring person has failed to give a timely
information statement to the Company or the date the shareholders voted not to
grant voting rights to the acquiring person's shares.
 
  Section 302A.673 of the MBCA generally prohibits any business combination by
the Company, or any subsidiary of the Company, with any shareholder which
purchases 10% or more of the Company's voting shares (an "interested
shareholder") within four years following such interested shareholder's share
acquisition date, unless the business combination is approved by a committee
of all of the disinterested members of the Board of Directors of the Company
before the interested shareholder's share acquisition date.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar with respect to the Common Stock will be
Norwest Bank Minnesota, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to the Offering, there has not been any public market for Common Stock
of the Company. Future sales of substantial amounts of Common Stock in the
public market could adversely affect the prevailing market price and impair
the Company's ability to raise additional funds.
 
  Upon completion of the Offering, the Company will have outstanding an
aggregate of 9,269,038 shares of Common Stock, assuming the issuance of
3,000,000 shares of Common Stock offered by the Company hereby. Of the total
outstanding shares of Common Stock, 3,000,000 shares will be freely tradeable
without restriction or further registration under the Securities Act, unless
held by "affiliates" of the Company, as that term is defined in Rule 144 under
the Securities Act (whose sales would be subject to certain volume limitations
and other restrictions described below).
 
  The remaining 6,269,038 shares of Common Stock held by existing shareholders
upon completion of the Offering will be "restricted securities" as that term
is defined in Rule 144 under the Securities Act. The Company, its officers,
directors and certain of its shareholders (representing 6,126,035 of such
restricted shares) have agreed that they will not sell, directly or
indirectly, any Common Stock without the prior consent of Piper Jaffray Inc.
for a period of 180 days from the date of this Prospectus. Beginning on the
181st day after the date of this Prospectus, when agreements not to sell such
shares expire, approximately 716,239 of the restricted shares will become
eligible for immediate sale, subject to compliance with the volume limitations
and other restrictions of Rule 144, and approximately 1,413,045 of the
restricted shares may become eligible for immediate sale without restriction
pursuant to Rule 144(k).
 
  In general, under Rule 144, as currently in effect, if at least two years
have elapsed from the date that shares of Common Stock were acquired from the
Company or an affiliate of the Company, then the holder is entitled to sell in
"brokers' transactions" or to market makers, within any three-month period
commencing 90 days after the date of this Prospectus, a number of shares that
does not exceed the greater of (i) one percent of the then outstanding shares
of Common Stock (92,690 shares immediately after the Offering) or (ii)
generally, the average weekly trading volume in the Common Stock during the
four calendar weeks preceding the filing of a Form 144 with respect to such
sale, subject to certain other limitations and restrictions. In addition, a
person who is not deemed to have been an affiliate of the Company at any time
during the three months preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least three years, would be entitled to sell
such shares under Rule 144(k) without regard to the requirements described
above.
 
  The Company intends to file registration statements under the Securities
Act, covering approximately 1,913,333 and 300,000 shares of Common Stock
reserved for issuance under, respectively, the Stock Option Plans and the
Directors' Plan. Such registration statements are expected to be filed soon
after the date of this Prospectus and will automatically become effective upon
filing. Accordingly, shares registered under such registration statements will
be available for sale in the open market, unless such shares are subject to
vesting restrictions with the Company or the contractual restrictions
described above. "See "Management--Stock Option Plans."
 
  In addition, after the Offering, the holders of approximately 5,835,705
shares of Common Stock and warrants to purchase approximately 414,916 shares
of Common Stock (together, the "Registrable Securities") will be entitled to
certain rights to cause the Company to register the sale of such shares under
the Securities Act. After the Offering, if the Company proposes to register
any of its securities under the Securities Act for its own account, holders of
Registrable Securities are entitled to notice of such registration and are
entitled to include Registrable Securities therein, provided, among other
conditions, that the underwriters of any such offering have the right to limit
the number of shares included in such registration. The holders of the
Registrable Securities may require the Company to prepare and file a
registration statement under the Securities Act at its expense, and the
Company is required to use its best efforts to effect such registration,
subject to certain conditions and limitations; provided that the Company shall
not be required to obtain the effectiveness of any such registration statement
until six months after the date of this Prospectus, at the earliest. The
Company is not obligated to effect more than one of these shareholder-
initiated registrations. Holders of not fewer than 100,000 Registrable
Securities may require the Company to file not more than two additional
registration statements per
 
                                      44
<PAGE>
 
calendar year on Form S-3 under the Securities Act, subject to certain
conditions and limitations. Registration of such shares would result in such
shares becoming freely tradeable without restriction under the Securities Act
(except for shares purchased by affiliates of the Company) immediately upon
the effectiveness of such registration.
 
  The Company can make no prediction as to the effect, if any, that sales of
shares of Common Stock or the availability of Common Stock for sale will have
on the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of the Common Stock in the public markets or the
perception that such sales will occur could adversely affect the market price
or the future ability to raise capital through an offering of its equity
securities. See "Risk Factors--Risk of Future Sales of Common Stock."

  Subject to the terms and conditions of the Purchase Agreement, the
Underwriters have agreed to purchase all of the Common Stock being sold
pursuant to the Purchase Agreement, if any is purchased (excluding shares
covered by the over-allotment option granted therein). In the event of a
default by any Underwriter, the Purchase Agreement provides that in certain
circumstances purchase commitments of the nondefaulting Underwriters may be
increased or the Purchase Agreement may be terminated.
 
  The Representatives have advised the Company that the Underwriters propose
to offer Common Stock directly to the public at the initial public offering
price set forth on the cover page of this Prospectus and to certain dealers at
such price less a concession not more than $0.37 per share. Additionally, the
Underwriters may allow, and such dealers may reallow a concession not in
excess of $0.10 per share to certain other dealers. After the Offering, the
initial public offering price and other selling terms may be changed by the
Underwriters.
 
  The Company has granted to the Underwriters an option, exercisable by the
Representatives within 30 days after the date of the Purchase Agreement, to
purchase up to an additional 450,000 shares of Common Stock at the same price
per share to be paid by the Underwriters for the other shares offered hereby.
If the Underwriters purchase any of such additional shares pursuant to this
option, each Underwriter will be committed to purchase such additional shares
in approximately the same proportion as set forth in the table above. The
Underwriters may exercise the option only for the purpose of covering over-
allotments, if any, made in connection with the distribution of the Common
Stock offered hereby.
 
  The Representatives have informed the Company that neither they, nor any
other member of the National Association of Securities Dealers, Inc. (the
"NASD") participating in the distribution of the Offering, will make sales of
shares of Common Stock offered hereby to accounts over which they exercise
discretionary authority without the prior specific written approval of the
customer.
 
  The Offering of the shares of Common Stock is made for delivery when, as and
if accepted by the Underwriters and subject to prior sale and to withdrawal,
cancellation or modification of the Offering without notice. The Underwriters
reserve the right to reject an order for the purchase of shares in whole or in
part.
 
                                      46
<PAGE>
 
  The officers and directors of the Company and certain other shareholders
designated by the Representatives, which will beneficially own in the
aggregate 6,126,035 shares of Common Stock after the Offering, have agreed
that they will not sell, offer to sell, distribute or otherwise dispose of any
shares of Common Stock owned by them prior to the date of the Prospectus for a
period of 180 days after the date of this Prospectus, without the prior
written consent of Piper Jaffray Inc. See "Shares Eligible For Future Sale."
The Company has agreed that it will not, without the Representatives' prior
written consent, offer, sell, issue or otherwise dispose of any shares of
Common Stock, options or warrants to acquire shares of Common Stock or
securities exchangeable for or convertible into shares of Common Stock during
the 180-day period following the date of this Prospectus, except that the
Company may issue shares upon the exercise of options and warrants granted
prior to the date hereof, and may grant additional options under the Stock
Option Plans and Directors' Plan.
 
  Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price for the Common Stock has been determined by
negotiation among the Company and the Representatives. Among the factors
considered in determining the initial public offering price were prevailing
market and economic conditions, estimates of the business potential and
prospects of the Company, the present state of the Company's business
operations, an assessment of the Company's management and the consideration of
the above factors in relation to the market valuation of companies in related
businesses. See "Risk Factors--No Prior Public Market; Possible Volatility of
Price."
 
  The Company has agreed to indemnify the Underwriters and their controlling
persons against certain liabilities, including liabilities under the
Securities Act, and to contribute to payments the Underwriters may be required
to make in respect thereof.
 
                              VALIDITY OF SHARES
 
  The validity of the securities offered hereby will be passed upon for the
Company by Dorsey & Whitney LLP, Minneapolis, Minnesota, and for the
Underwriters by Faegre & Benson LLP, Minneapolis, Minnesota. Members of Dorsey
& Whitney LLP own 40,300 shares of Common Stock and warrants to purchase an
additional 14,814 shares of Common Stock.

                        REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Integ Incorporated
 
  We have audited the accompanying balance sheets of Integ Incorporated as of
December 31, 1994 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, 1995, and for the period from April 3,
1990 (inception) to December 31, 1995. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Integ Incorporated at
December 31, 1994 and 1995 and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1995, and
for the period from April 3, 1990 (inception) to December 31, 1995, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1995
 
1. DESCRIPTION OF BUSINESS
 
  Integ Incorporated was formed in April 1990 and is a development stage
company engaged in the development of the Lifeguide System, a painless and
bloodless hand-held glucose monitoring product for use by people with
diabetes. 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
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments purchased with a
maturity of three months or less when purchased to be cash equivalents. At
December 31, 1995 and March 31, 1996, the Company's investment in government
securities approximated market value, with no resulting unrealized gains and
losses recognized.
 
 Furniture and Equipment
 
  Furniture and equipment are recorded at cost and depreciated primarily on a
straight-line basis over estimated useful lives of five years.
 
 Income Taxes
 
  The Company accounts for income taxes under the liability method. Deferred
income taxes are provided for temporary differences between the financial
reporting and tax bases of assets and liabilities.
 
 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.
 
 Stock Based Compensation
 
  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation." The statement prescribes accounting and reporting standards for
all stock-based compensation plans under a fair value method, including
employee stock options and restricted stock grants. The statement, effective
for fiscal years that begin after December 15, 1995, encourages but does not
require expense recognition for the fair value of stock based compensation.
The Company has not determined the impact of the new statement on its
financial statements; however, it expects to continue to follow APB Opinion
No. 25 under the intrinsic value method and provide the required pro forma
disclosures for net income and earnings per share had the fair value method
been adopted.
 
 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 method, as if they were outstanding
for all periods presented.
 
  Pro forma net loss per share computed in accordance with Accounting
Principles Board Opinion No. 15 and SAB No. 83, after giving effect to the
conversion of all series of convertible preferred stock into common stock,
would be $(.81) and $(.22) for the year ended December 31, 1995 and three
months ended March 31, 1996 on 6,269,000 and 7,919,000 pro forma weighted
average number of shares outstanding, respectively.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Automatic Conversion of Preferred Stock
 
  Upon the closing of the offering covered by this Prospectus, all outstanding
shares of convertible preferred stock will automatically be converted into an
aggregate of 5,835,705 shares of common stock. Assuming conversion of the
convertible preferred stock, but without giving effect to the offering itself,
the unaudited pro forma amounts of shareholders' equity at March 31, 1996 are
presented in the balance sheets.
 
 Interim Financial Information
 
  The accompanying financial statements as of March 31, 1996 and for the
three-month periods ended March 31, 1996 and March 31, 1995 are unaudited. In
the opinion of the management of the Company, these financial statements
reflect all adjustments, consisting only of normal and recurring adjustments,
necessary for a fair presentation of the financial statements. The results of
operations for the three-month period ended March 31, 1996 are not necessarily
indicative of the results that may be expected for the full year ending
December 31, 1996.
 
 Reclassifications
 
  Certain amounts in the 1994 financial statements have been reclassified to
conform with the 1995 presentation.
 
3. LONG-TERM DEBT AND LEASES
 
  The Company leases its office facility and certain office equipment under
operating leases. Rent expense of approximately $17,100, $96,400, $251,700 and
$91,800 was recorded for noncancelable operating leases and sub-leases for the
years ended December 31, 1993, 1994 and 1995 and the three months ended March
31, 1996, respectively. Future minimum lease commitments for operating leases
with remaining terms in excess of one year are payable during the years ending
December 31 as follows:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
  During June 1995, the Company received gross proceeds of approximately
$22,400,000 from the sale of 5,604,655 shares of its Series E Convertible
Preferred Stock, Class 1. During January 1995, in anticipation of its 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 Management), 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,
including warrants for 222,222 shares issued to MIF II and warrants for 74,074
shares issued to Artesian Management. 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
 
  As of March 31, 1996, the Company had authorized 20,000,000 shares of
capital stock, of which 9,173,957 shares have been designated as various
series of preferred stock, and 433,333 shares have been issued as common
stock. The 10,392,710 remaining authorized shares are undesignated as of March
31, 1996. According to the Company's Restated Articles of Incorporation, any
shares issued without designation by the Company's Board of Directors are
considered to be common stock with equal rights and preferences.
 
 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 will have no effect upon the
numbers of shares of preferred stock issued and outstanding (as opposed to the
conversion prices of the preferred stock and the numbers of shares of common
stock into which the preferred stock will convert). 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 913,333
shares of the Company's common stock have been reserved for issuance under all
three plans as of March 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, subject to shareholder approval.

  Options issued under the plans expire at various dates during the period
from October 2000 through March 2006.
 
  In addition during 1991 and 1993, the Company granted options outside the
plans to purchase 42,993 shares of the Company's common stock at $.84 per
share to Medical Innovation Fund (MIF), a significant shareholder of the
Company (see Note 8).
 
  During August 1995, the Company extended the exercise period of stock
options to purchase 17,999 shares of common stock issued in 1990 to three
individuals for an additional five-year period. The value of this extension
was determined to be $6,750, based on the difference between the exercise
price of $.83 and the fair market value of $1.20 per share, and was expensed
as compensation in 1995.
 
  During April 1996, the Company granted options to purchase 273,995 shares of
the Company's common stock at $9.75 per share, exercisable for ten years, to
officers and employees of the Company. In addition, the Board of Directors
adopted the 1996 Directors' Stock Option Plan, subject to shareholder
approval, under which each non-employee director will receive an option to
purchase 15,000 shares of the Company's common stock, for an aggregate of
105,000 shares, at the closing of this initial public offering.
 
 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 the three months ended March 31, 1996, $109,937 and $7,527 was
expensed, respectively. In addition to the shares being held by the Company
until the restriction lapse occurs,

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
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 the period from August 16, 1995 through March 13, 1996, options were
granted to purchase a total of 297,134 shares of the Company's common stock at
exercise prices of $1.20 per share. The Company recognized $960,208 and
$35,202 during the year ended December 31, 1995 and the three months ended
March 31, 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 year ended December 31, 1995 and the three months ended March
31, 1996, $77,169 and $87,205, respectively, was expensed.
 
  The remaining unamortized deferred compensation is expected to be charged to
operations as follows:

credit line. 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 13,587
shares of common stock were issued concurrent with the March 1996 funding.
These warrants expire in December 2003. The value of these warrants was
determined to be $48,915 based on the difference between the warrant exercise
price and the estimated fair market value of the common stock and will be
expensed over the term of the loan agreement.

8. RELATED PARTY TRANSACTIONS
 
  Laboratory and office furniture and equipment used by the Company with an

be $83,962 based on the difference between the stated interest rate and the
Company's estimated effective borrowing rate for the term of the lease.
Approximately $14,350 and $4,200 was charged to interest expense during the
year ended December 31, 1995 and the three months ended March 31, 1996,
