   This summary highlights information contained in this prospectus. You should
read the entire prospectus, especially "Risk Factors" and the consolidated
financial statements and notes, before deciding to invest in shares of our
common stock.

                                  Our Company

   LXN is a medical technology company that develops, manufactures and markets
products to help people with diabetes better manage their disease. In
Charge(TM), our FDA-cleared consumer product, includes a proprietary home-based
test called GlucoProtein(R), which measures overall glucose control. Our
GlucoProtein test allows patients and health care professionals to better
monitor the overall effectiveness of diabetes treatment and make timely and
effective therapy changes. We launched In Charge regionally in October 1999,
and based on the success of this launch, we plan to aggressively pursue
nationwide sales and marketing. We also market Duet(R), a product for the
health care professional that also performs the GlucoProtein test. We believe
our products and technologies are well-suited to fill an unmet need of a
growing population of diabetes patients with poor glucose control.

                                The Opportunity

   Diabetes is a chronic, progressively debilitating disease in which the human
body loses its ability to maintain a normal level of glucose in the
bloodstream. The disease can result in severe complications such as blindness,
amputation, kidney failure, and cardiac failure. To prevent these
complications, patients attempt to maintain their average glucose levels within
a normal range. As one attempt to monitor this, patients periodically check
their blood glucose to get point-in-time measurements. There were estimated to
be over two billion point-in-time blood glucose tests performed in the U.S. in
1999.

   Of the estimated 10.3 million people in the U.S. diagnosed with diabetes,
approximately 90% have a form known as Type 2 diabetes. These patients are
typically not dependent on frequent insulin injections to maintain normal
glucose levels. Rather, their physicians typically treat them with some
combination of oral medications, diet modification, and exercise programs.
Since the majority of these patients do not rely on frequent glucose testing to
adjust their treatment regimen, they tend not to test often enough to get a
true indication of their overall control. Tests for overall glucose control are
more meaningful for Type 2 patients than point-in-time measurements, since
blood glucose can fluctuate widely throughout the day.

   Overall blood glucose control may be determined by measuring the level of
glycated proteins in the bloodstream. High levels of blood glucose lead to high
levels of glycated proteins. Two glycated proteins measured are HbA1c and
fructosamine. An HbA1c measurement represents the average level of glucose over
the preceding three months, while fructosamine represents the prior three
weeks. Higher levels of glycated proteins serve as a warning sign that overall
glucose levels are not in control, even if point-in-time glucose tests indicate
a normal level. High levels of glycated proteins have been shown to correlate
with increased risk for the severe complications of diabetes. Despite this,
glycated protein tests have not been widely used because they typically require
a visit to the laboratory, are expensive, and results are not available in time
for a physician to make timely therapy adjustments. In addition, the
three month time window of HbA1c does not allow patients to easily recall
behaviors that could have caused the poor levels of overall glucose control.

<PAGE>


                                 GlucoProtein(R)

   Our proprietary GlucoProtein test is the only over-the-counter home-based
test that measures the patient's average blood glucose level over three weeks
rather than three months. We believe that our test enables patients to take a
more active role in their therapy and is ideally suited for the large Type 2
population. The feedback from GlucoProtein tests enables patients and their
health care professionals to more meaningfully analyze past behaviors and
treatment regimens, and alter them to achieve better glucose control.

   In December 1999 the results from a 25-patient clinical trial demonstrated
that a diabetes treatment regimen using a combination of once-weekly
GlucoProtein testing and regular point-in-time glucose testing resulted in
better blood glucose control than a regimen using only regular point-in-time
glucose testing. The trial measured HbAlc levels, a well-accepted marker of
overall blood glucose control, in patients at the beginning of the trial and at
the end of the trial, three months later. The group of patients using our
GlucoProtein testing achieved a 13% reduction in average HbAlc levels while the
group that did not use GlucoProtein testing did not achieve a statistically
significant change in average HbAlc levels. The chance that these results could
have occurred by accident is less than 1 in 10,000. A 10% reduction in HbAlc
levels has been shown in other studies to reduce the risk of severe
complications such as blindness by up to 45%.

                            In Charge(TM) and Duet(R)

   We currently market two GlucoProtein products: In Charge for use by patients
and Duet for use by health care professionals. In Charge has three components:
a GlucoProtein test strip, a glucose test strip and a hand-held, electronic
monitor. Duet is a similar system designed for in-office use by a health care
professional. The In Charge GlucoProtein test strips are packaged together with
glucose test strips, and the package is covered by Medicare reimbursement. In
addition, several major health care payors and managed care organizations
already cover our products. Typically we sell the full system, then receive
recurring revenues from sales of disposable test strips. Customers can purchase
In Charge as a non-prescription product through multiple channels, including
national retail chains, independent pharmacies, mail-order pharmacies, or
directly from us. We currently have a regional sales force, and we will build a
national sales force to market our products.

                                  Our Strategy

   Our strategy has four major components:

  . Establish GlucoProtein Home Testing as the Standard of Care for
    Management of Type 2 Diabetes.  We will sponsor additional clinical
    trials to provide further support that GlucoProtein home testing improves
    medical outcomes. We intend to present the results to key medical
    organizations such as the American Diabetes Association to facilitate
    adoption of GlucoProtein home testing as a standard of care. We will
    publicize the results to promote the continued adoption of GlucoProtein
    and In Charge by managed care and health care payors.

  . Aggressively Pursue Nationwide Sales and Marketing Efforts. Our
    nationwide sales force will promote In Charge to diabetes-focused
    physicians and educators, opinion leaders and pharmacists. We will
    promote Duet to physicians because we believe doctors who use Duet in
    their office will recommend that their patients use In Charge at home. In
    parallel, we plan to market In Charge directly to patients.

  . Enhance Technology Leadership Position. We intend to improve our existing
    products to meet changing consumer requirements and to measure additional
    disease parameters common in diabetes patients. Our goal is to have
    GlucoProtein testing accepted as a clinical decision tool in the use of

                                       5
<PAGE>

   drug treatments for diabetes. Thus, we target pharmaceutical companies
   with diabetes drugs that could use GlucoProtein testing as a clinical
   research tool or could incorporate it as part of their drug dosing.
   Bristol-Myers Squibb, for example, has incorporated In Charge into two
   clinical trials to support its newest Type 2 diabetes drug.

  . Broaden Reimbursement Coverage. We will continue to target additional
    health care payors and managed care organizations to obtain
    reimbursement. Although Medicare already covers our combined package, we
    are pursuing reimbursement of our GlucoProtein test strips separately
    from the combined product.

                                  RISK FACTORS

   Any investment in shares of our common stock involves a high degree of risk.
You should consider carefully the following information about these risks,
together with the other information contained in this prospectus before you
decide to buy our common stock. If any of the following risks actually occur,
our business, results of operations and financial condition would likely
suffer. In these circumstances, the market price of our common stock could
decline, and you may lose all or part of the money you paid to buy our common
stock.

We are dependent upon In Charge and Duet for our future revenues and growth,
and if we do not achieve adequate sales volumes of these products, our
business, financial condition and operating results will be seriously harmed.

   We expect that In Charge and Duet will account for a substantial majority of
our revenues for the foreseeable future. Our ability to generate significant
revenues will be dependent upon our ability to achieve adequate sales volumes
of these products and their acceptance among physicians, patients and health
care payors. We face risks related to our ability to:

  . build a sales and marketing organization to support the national
    commercial launch of In Charge;

  . demonstrate the benefits of our glycated protein monitoring systems to
    physicians, patients and diabetes organizations like the American
    Diabetes Association, or ADA;

  . demonstrate the cost-effectiveness of In Charge to health care payors and
    obtain reimbursement approvals from Medicare and private health care
    payors; and

  . compete in the diabetes home testing market, which is dominated by large,
    well financed and established competitors.

   If we fail to adequately manage these risks and other risks that we will
encounter, we will likely fail to successfully market In Charge and Duet and
our revenues will not grow or will grow more slowly than we expect. In this
event, our business, financial condition and operating results would be
seriously harmed, and our stock price would likely decline.

We have a limited operating history, have incurred significant operating losses
and may never build a sustainable business or achieve profitability, and if we
fail to do so, our stock price will likely decline.

   We were incorporated in 1993 and have a limited operating history. To date,
our operations have been focused primarily on the development of our products
and technologies. We have had only limited commercial sales. Accordingly, our
historical results of operations provide only a limited basis for assessing our
future prospects. In addition, we incurred operating losses of $12.0 million in
1998, $10.2 million in 1999 and $4.8 million in the six months ended June 30,
2000 and we had an accumulated deficit of $36.4 million at June 30, 2000.

   We anticipate that our operating expenses will increase significantly for
the foreseeable future as we continue to expand our sales and marketing,
manufacturing, clinical research and product development efforts. Accordingly,
in order for us to achieve profitability, we will need to significantly
increase our revenues. If our revenues do not continue to grow, we may not be
able to achieve or maintain profitable operations in the future. Even if we do
achieve significant revenues, we expect to incur significant net losses over
the next several years and these losses could increase. If we fail to achieve
significant revenue growth or profitability, our stock price will likely
decline.

If In Charge and Duet fail to achieve market acceptance in a timely manner, our
revenues and our business could be seriously harmed.

   Because substantially all of our revenues for the foreseeable future will
come from the sale of In Charge and Duet, our future operating results will
depend upon market acceptance of these products among physicians, patients, and
health care payors. If we are unable to convince these parties of the benefits
of glycated protein testing in combination with glucose testing as a more
effective alternative to glucose-only testing, and of the utility of our
products in particular, we may not be able to generate sufficient revenues to
achieve our business objectives.

   Physicians and other health care professionals will not recommend or use our
products unless they determine, based on their professional experience, long
term clinical data, relative cost and other factors that our products provide
an effective and attractive method for supplying clinical information useful to
the management of diabetes. To date, In Charge and Duet have been utilized by
only a limited number of customers. In addition, no independent clinical
studies regarding these products have been published and the principal clinical
study seeking to demonstrate the benefits of weekly glycated protein testing
involved only 25 patients and was conducted in December 1999. Furthermore, a
significant factor in our ability to achieve acceptance of our products among
physicians will be endorsements and recommendations from diabetes organizations
and opinion leaders in the field. To date, we have not received any
endorsements or recommendations from these organizations. Finally, we may be
adversely affected by physician tendencies to slowly adopt new products and
treatment practices due to perceived liability risks and concerns relating to
reimbursement from health care payors.

   Acceptance among patients will depend upon not only recommendations by
physicians and other health care providers but upon the success of our consumer
marketing programs. We must establish the In Charge brand among diabetes
patients and must also convince diabetes patients of the clinical advantages of
using our products.

   Acceptance among health care payors will depend upon their assessments of
the cost-effectiveness and clinical benefits of our products. It may be
necessary for us to generate a significant body of clinical data regarding our
products that we can present to payor organizations in order to achieve such
acceptance. This would be a lengthy, expensive process. In addition, some payor
organizations may conduct their own independent assessments of our products.

   For these reasons, we may fail to achieve acceptance of our products among
physicians, patients and health care payors. If we fail to achieve such
acceptance, our revenues would not grow or would decline, our operating losses
would likely increase, and our business and financial condition would be
seriously harmed. Our stock price would also likely decline.

We face significant competition from major medical technology companies with
greater resources than we have, and if we fail to compete effectively, our
business will be seriously harmed.

   The home glucose monitoring industry is intensely competitive. Physicians
and patients are accustomed to using other glucose monitoring products sold by
competitors of ours that have significant marketing, technical and financial
resources and well-established products, markets and distribution channels.

   Our primary competitors are the manufacturers of home blood glucose tests
and manufacturers of HbA1c tests designed for laboratories and physicians'
offices. Home blood glucose test manufacturers include the Lifescan unit of
Johnson & Johnson, Roche Diagnostics, Bayer AG and Abbott Laboratories. Each of
these companies offers a glucose-only test using a battery-operated, hand-held
monitor with a single-use test strip. Manufacturers of physician's office and
laboratory HbA1c test devices include Roche Diagnostics, Sigma Chemical Co. and
Bayer AG. To date, none of these companies has introduced an in-home glycated
protein test. One company, Metrika, recently announced that it received
regulatory approval for an in-home HbA1c test that requires a prescription,
although this product has not yet been commercially introduced.


                                       10
<PAGE>

   Many of our competitors and potential competitors have substantially greater
capital resources, research and development staff and facilities than we have.
In general, our competitors also have greater experience than we have in
research and new product development, obtaining regulatory approvals and
manufacturing and marketing medical devices. As a result, many of our current
competitors could, if they elect to do so, design and develop an in-home
glycated protein test. These companies could represent potential additional
competition for us.

   The products offered by our competitors compete with our products based on
price and access to distribution channels. Competition within the glucose
monitoring industry could force us to reduce the price of our products or
implement purchase incentive programs or similar price discounting programs. In
addition, competitors, because of their high sales volumes and broader range of
products, may be more successful in establishing relationships with major
retailers, including national and regional pharmacy and discount store chains.
As a result, these competitors may get better store shelf placement for their
products and other favorable treatment from retailers. Competitors may also be
able to enter into more favorable arrangements with managed care companies and
health care payors. If our competition forces us to reduce the prices for our
products or makes it more difficult to place our products in major retail
outlets or obtain reimbursement from health care payors, our business,
financial condition and operating results would be seriously harmed.

We have limited experience in undertaking major new product introductions, and
we may encounter difficulties in successfully rolling out In Charge on a
national basis.

   We have limited sales and marketing experience and have not yet successfully
introduced a new product on a national basis. To date, our sales and marketing
efforts for In Charge have been focused primarily on introduction of In Charge
on a regional basis in discrete geographic markets. In order for us to achieve
our business objectives, we will need to successfully roll out In Charge on a
national basis. This will require us to hire, train and manage a large sales
force deployed in major geographic markets throughout the United States. We
currently have only a limited sales force and have no experience in hiring,
training and managing a large sales force or in selling our products through a
large sales force. There are significant risks involved in building and
managing a sales force. There is intense competition for skilled sales and
marketing employees, especially for people who have experience selling medical
devices to physicians and through consumer marketing channels in our target
markets. We may be unable to hire skilled individuals to sell our products. Any
inability to build our direct sales force will materially and negatively impact
our growth.

   In addition, in connection with the national rollout of In Charge, we will
need to successfully penetrate major national and regional discount retail and
pharmacy chains and other retail outlets at which consumer medical products are
sold. We have limited experience in marketing to major retailers and may,
relative to our competitors, be at a disadvantage in this regard due to our
small size, lack of a diversified product portfolio, limited operating history
and limited marketing experience. If we are unable to successfully penetrate
major and regional retailers, our sales of In Charge will be harmed.

Only one clinical study has been completed that validates the benefits of home-
based fructosamine testing. We will need to sponsor additional clinical studies
to validate our GlucoProtein test, and if we are unable to do so, our market
acceptance and revenues will be seriously harmed.

   The clinical study that demonstrated the benefits of weekly fructosamine
testing as a means of managing overall glucose control in diabetes patients
involved only 25 patients over a period of three months. This study was
conducted in December 1999. We intend to sponsor additional clinical studies
with the objective of demonstrating the benefits of weekly home fructosamine
testing in larger patient populations. Acceptance of our products would be
seriously harmed if these future clinical studies do not produce results
similar to the initial study. In addition, studies in which patients are
followed for longer time periods may fail to confirm the benefits of weekly
fructosamine testing as compared to glucose-only testing, and this could also
seriously harm acceptance of our products. We also cannot be certain when we
will sponsor our future studies, or when or whether the results of these
studies will be compiled and published. Accordingly, if we do not achieve

                                       11
<PAGE>

favorable results in these future clinical studies and we are unable to have
these results compiled and published in a timely manner, acceptance of our
products could be seriously harmed. This in turn would harm our revenues,
business, financial condition and operating results.

If health care payors do not reimburse health care providers for use of our
products, purchases of our products could be delayed or curtailed and our
revenues could decline.

   Physicians and patients may be reluctant to purchase our products if they do
not receive adequate reimbursement for the cost of our products from health
care payors, such as Medicare, Medicaid and private health insurance plans. To
date, only a limited number of private health care payors have agreed to
reimburse for the cost of our products. Until a sufficient amount of positive
clinical data has been published, insurance companies and other payors may
refuse to provide reimbursement for the cost of our products or may reimburse
at levels that are not acceptable to health care providers. Some payors may
refuse adequate reimbursement even upon publication of this data. Market
acceptance of our products will be limited unless physicians and patients can
obtain adequate levels of reimbursement from governmental and major private
health care payors.

   Many health care payors enter into purchasing agreements under which they
agree to purchase particular products or classes of products from a single
vendor in order to obtain more favorable pricing or other terms. For example, a
health care insurance company may have an arrangement with one of our
competitors for the purchase of blood glucose monitors. Health care payors may
find it more advantageous to enter into such agreements with our competitors,
particularly those that offer a broad range of products. Accordingly, health
care payors may not enter into purchasing agreements with us for our products,
even if physicians and patients prefer our products or our products are
demonstrated to be superior to other existing products. If we experience
difficulty in entering into purchasing agreements with health care payors, our
revenues and our business, financial condition and operating results will
likely be harmed.

   Even if health care payors provide adequate reimbursement for our products,
adverse changes in health care payors' reimbursement policies generally, or
with respect to blood glucose monitoring products in particular, could preclude
market acceptance of our products and harm our revenue growth. We cannot
predict what changes will be made in reimbursement policies of health care
payors.

Fluctuations in our operating results could negatively impact our stock price.

   Our revenues and results of operations have fluctuated significantly in the
past and may fluctuate significantly in the future. For example, our revenues
declined from 1998 to 1999. Factors that may cause our results to fluctuate
significantly in the future include:

  . the volume and timing of orders for our products;

  . announcements regarding clinical studies involving our products;

  . sales and marketing programs and initiatives undertaken by us;

  . actions taken by our competitors, including changes in product pricing
    and introduction of new products;

  . our ability to develop, obtain regulatory clearance for, and
    commercialize, new and enhanced products on a timely basis;

  . changes in the availability of third party reimbursement to users of our
    products; and

  . write-offs for unsold inventory.

   Many of our operating expenses, including costs of facilities, personnel,
marketing programs and overhead, are relatively fixed in nature. We cannot
adjust these expenses in the short term. If our revenues decline or do not grow
as anticipated, we may not be able to reduce our operating expenses
accordingly.

                                       12
<PAGE>

Failure to achieve anticipated revenue levels could significantly harm our
results of operations for one or more fiscal periods. Due to the possibility of
fluctuations in our revenues and expenses, we believe that quarter to quarter
comparisons of our operating results are not a good indication of our future
performance. In any event, our operating results in a future fiscal period may
fail to meet the expectations of stock market analysts and investors. In that
case, our stock price would likely decline.

Our revenues depend on a limited number of products, and we need to develop new
products or improve existing products to grow our business successfully.

   We currently derive all our revenues from the sale of three products. We may
not be able to grow our revenues sufficiently solely from sales of our existing
products. Our future success will depend in part on our ability to continue to
improve our existing products and develop, market and sell new products for
diabetes monitoring. We cannot assure you that we will be successful in
improving our existing products or developing new products, that we can obtain
regulatory clearance to market new products or that we can manufacture these
new products at an acceptable cost. If we fail to successfully develop, market
and sell improved or new products, our business, financial condition and
operating results could be harmed.

New products and technologies could prove to be superior to ours and could
render them obsolete, in which case physicians and patients may reduce or
eliminate the use of our products.

   Our competitors and potential competitors may succeed in developing or
marketing products and technologies that will be more acceptable in the
marketplace than our diabetes monitoring devices. New products and technologies
could render ours obsolete or noncompetitive. New products and technologies
could include HbA1c monitoring devices for home use or minimally invasive or
non-invasive tests for accurately measuring blood glucose levels. In addition,
numerous researchers are investigating alternative treatments or cures for
diabetes. If any of these research efforts are successful in reducing diabetes
complications, the demand for our products could be reduced.

Patents and other proprietary rights provide uncertain protections, and if we
are unable to protect our intellectual property rights, our business could be
seriously harmed.

   Our commercial success will depend, in large part, on our ability to obtain
patent protection on many aspects of our business, including the products and
methods we develop. Patents issued to us or under which we are licensed may not
provide us with substantial protection or be commercially beneficial to us. The
issuance of a patent is not conclusive as to its validity or its
enforceability. In addition, our pending U.S. and international patent
applications, which contain claims relating to material aspects of our products
that are not currently protected by issued patents, may not result in issued
patents. If our patent applications do not result in issued patents, our
competitors may obtain rights to commercialize our discoveries which would harm
our competitive position.

   Competitors may be able to design around our patents or develop products
which are comparable to ours. In addition, the laws of some foreign countries
may not protect our intellectual property rights to the same extent as do the
laws of the U.S. In the event a competitor infringes upon our patent or other
intellectual property rights, enforcing those rights may be costly, difficult
and time consuming. Even if successful, litigation to enforce our intellectual
property rights or to defend our patents against challenge could be expensive
and time consuming and could divert our management's attention. We may not have
sufficient resources to enforce our intellectual property rights or to defend
our patents against a challenge.

   Our success also depends upon the skills, knowledge and experience of our
scientific and technical personnel. The confidentiality agreements required of
our employees and that we enter into with other parties may not provide
adequate protection for our trade secrets, know-how or other confidential
information or prevent any unauthorized use or disclosure or the unlawful
development of competing products by others. If any of our intellectual
property is disclosed, our business may suffer. In addition, many of our

companies, where they were conducting research in areas similar to those that
we now pursue. As a result, we could be subject to allegations of trade-secret
violations and other claims relating to the intellectual property rights of
these companies.

If we are unable to continue to license the intellectual property of third
parties necessary to develop and commercialize our products, our business will
be seriously harmed.

   We license and may continue to license technologies relevant to our
products. In particular, we have licensed certain technologies relating to the
GlucoProtein strip under a non-exclusive license with one of our competitors in
the home glucose monitoring market and the office- and lab-based glycated
protein testing market. We depend, and will continue to depend, on these and
other licensing arrangements for intellectual property rights that are
important to our business. Our rights may be terminated if we do not perform as
required under these arrangements. In addition, these third parties may also
breach or terminate their agreements with us or otherwise fail to conduct their
activities in connection with our relationships in a timely manner. In
particular, the licensor may terminate its license agreement with us if we fail
to make royalty payments or comply with other requirements under the license in
a timely manner or otherwise materially breach the agreement. If any of our
licenses or relationships are terminated or breached, we may:

  . lose our rights to develop and market our products;

  . lose patent and/or trade secret protection for our products;

  . experience significant delays in the development or commercialization of
    our products; and

  . not be able to obtain any other licenses to alternative technologies on
    acceptable terms.

   Further, the non-exclusive nature of our license agreement leaves open the
possibility for a third party or competitor to license the same technology and
develop competing products. In addition, the license does not preclude this
competitor from introducing a competing product for in-home glycated protein
testing. If this were to occur, the resulting additional competition could
reduce the market for our products, reduce our revenues and growth and harm our
business and financial condition.

We may face significant expense and liability as a result of litigation or
other proceedings relating to patents and other intellectual property rights of
others.

   The medical technology industry has in the past been characterized by a
substantial amount of litigation and related administrative proceedings
regarding patents and intellectual property rights. In addition, major medical
device companies have used litigation against emerging growth companies as a
means of gaining a competitive advantage.

   Should third parties file patent applications or be issued patents claiming
technology also claimed by us in pending applications, we may be required to
participate in interference proceedings in the U.S. Patent and Trademark Office
to determine the relative priorities of our inventions and the third parties'
inventions. We or our licensors could also be required to participate in
interference proceedings involving our issued patents and pending applications
of another entity. An adverse outcome in an interference proceeding could
require us to cease using the technology or to license rights from prevailing
third parties. There is no guarantee that any prevailing party would offer us a
license or that such a license could be acquired on commercially acceptable
terms.

   Third parties may claim that we are using their patented inventions and may
go to court to stop us from engaging in our normal operations and activities.
Such lawsuits are expensive to defend and conduct and would also consume and
divert the time and attention of our management. A court may decide that we are
infringing a third party's patents and may order us to cease the infringing
activity. The court could also order us to pay damages for the infringement.
These damages could be substantial and could harm our business, financial
condition and operating results. Moreover, we cannot guarantee you that the
prevailing patent owner would offer us a license so that we could continue to
engage in activities claimed by the patent, or that such a license, if made
available to us, could be acquired on commercially acceptable terms.

                                       14

   If we were unable to obtain any necessary license following an adverse
determination in litigation or in interference or other administrative
proceedings, we could have to redesign our products to avoid infringing a third
party's patent and could temporarily or permanently have to discontinue
manufacturing and selling some of our products. If this were to occur, it would
seriously harm our business, financial condition and operating results.

If we are unable to increase our manufacturing capabilities to meet customer
demand, our business could suffer.

   To be successful, we must manufacture our products in commercial quantities
at acceptable costs and in compliance with regulatory requirements. If we are
unable to establish reliable, cost-effective manufacturing of our products at
levels sufficient to meet customer requirements, we could lose customers and
our business could suffer. At the present time, we have limited manufacturing
experience. Our manufacturing operations are currently focused on the
manufacturing of glucose and GlucoProtein test strips. As we increase our
manufacturing volume and the number of product designs for our devices, the
complexity of our manufacturing processes will increase. Successful
manufacturing operations require scaling up production of existing and new
products, controlling production yields, quality control and assurance,
component supply management and avoiding material and personnel shortages. In
addition, we have to remain in compliance with regulatory requirements for the
manufacture of our products. If we are unable to successfully expand or
properly manage our manufacturing operations or are otherwise unable to meet
customer demand for our products, our business, financial condition and
operating results would suffer.

We are dependent on a single manufacturer for the production of our In Charge
and ExpressView monitors, and any material disruption in our relationship with
that manufacturer could harm our business.

   We use one third party manufacturer in Germany to manufacture all of our
monitors for In Charge and ExpressView. We have limited control over this
manufacturer, and if it fails to manufacture these monitors with the desired
quality and in a timely manner as our sales volume increases, our business
could be negatively affected. If we or this manufacturer terminate our existing
agreement, finding a replacement manufacturer could be a time-consuming and
expensive process and our sales could decrease during any transition period.
These events would harm our business, financial condition and operating
results.

If we or our suppliers fail to comply with the FDA Quality System Regulations,
manufacturing operations could be delayed and our business could be harmed.

   Our manufacturing processes are required to comply with the Quality System
Regulations, or QSR, which covers the methods and documentation of the design,
testing, production, control, quality assurance, labeling, packaging and
shipping of our products. The U.S. Food and Drug Administration, or FDA,
enforces the QSR through periodic unannounced inspections. We have never been
through a QSR inspection, and we cannot assure you that we would pass such an
inspection. Our manufacturing lines at our outside manufacturer have also not
been inspected to date. If we or any of our suppliers fail a QSR inspection,
our operations could be disrupted and our manufacturing delayed. Failure to
take corrective action in response to an adverse QSR inspection could force a
shut-down of our manufacturing operations or those of our suppliers, and a
recall of our products, which would have a material adverse effect on our
product sales, revenues, and expected revenues. Furthermore, we cannot assure
you that our key component suppliers are or will continue to be in compliance
with applicable QSR requirements or will not encounter any manufacturing
difficulties. Any such event could have a material adverse effect on our
available inventory and product sales.

We are dependent on single-source suppliers for a number of components in our
test strips, and any disruption in the supply of these components could
negatively affect our business.

   Because a number of components of our test strips are supplied to us by
single-source suppliers, a disruption in the supply of these components could
negatively affect revenues. If we were unable to resolve any disruption, we
could be required to redesign our products which could significantly impair our
ability to sell

                                       15
<PAGE>

them. In addition to marketing any products containing new materials, we may be
required to make amended or new filings with regulatory authorities. This
clearance process may take a substantial period of time, and we may be unable
to obtain necessary regulatory clearance or approvals for any new material to
be used in our products on a timely basis, if at all. This could also create
supply disruptions that could negatively affect our business.

We depend on key employees in a competitive market for skilled personnel, and
without additional sales personnel and other employees, we cannot grow or
achieve profitability.

   We are highly dependent on the principal members of our management,
operations and research and development staff. Our future success will depend
in part on the continued service of these individuals and our ability to
identify, hire and retain additional personnel. In particular, in order to
implement our strategy for the nationwide launch of In Charge, we will need to
significantly increase the size of our sales force over the next 12 months. If
we are unable to hire and train enough sales personnel, our ability to
successfully launch In Charge will be impaired. The market for qualified sales,
technical and management personnel in Southern California, where our offices
are located, is extremely competitive and is expected to continue to be highly
competitive. Because the environment for qualified personnel is so competitive,
costs related to compensation may increase significantly. If we are unable to
attract and retain the personnel we need to support and grow our business, our
business will suffer.

We may need to raise additional capital in the future, which could result in
dilution to our stockholders.

   We anticipate that our existing capital resources, together with cash from
operations and the net proceeds from this offering, will be sufficient to fund
our operating and capital requirements for at least the next 12 months.
Nevertheless, we may need to raise additional capital. The amount of additional
capital that we will need to raise will depend on many factors, including the
extent to which In Charge and Duet gain market acceptance. In addition, we may
require additional financing in less than 12 months if we decide to expand more
rapidly than planned, develop new or enhanced products ahead of schedule, need
to respond to competitive pressures or decide to acquire complementary
products, businesses or technologies. If we raise additional funds through the
sale of equity, convertible debt or other equity-linked securities, it will
reduce your percentage ownership of our company. We may issue securities that
have rights, preferences and privileges senior to our common stock. If we raise
additional funds through collaborations or licensing arrangements, we may have
to relinquish rights to certain of our technologies or products, or grant
licenses to third parties on terms that are unfavorable to us. If future
financing is not available to us or is not available on terms acceptable to us,
we may not be able to fund our future needs which would have a material adverse
effect on our operating results and financial condition.

Our failure to obtain or maintain necessary FDA clearances or approvals could
hurt our ability to commercially distribute and market our products in the U.S.

   Our current products and products under development are medical devices and
are subject to extensive regulation in the U.S. and in foreign countries where
we intend to do business. Unless an exemption applies, each medical device that
we wish to market in the U.S. must first receive either 510(k) clearance or
premarket approval from the FDA. Either process can be lengthy and expensive.
The FDA's 510(k) clearance process usually takes from four to twelve months,
but may take longer. The premarket approval, or PMA, process is much more
costly, lengthy and uncertain. It generally takes from one to three years or
even longer. Delays in obtaining regulatory clearance or approval will
adversely affect our revenues and profitability. Although we have obtained
510(k) clearance for In Charge, Duet and ExpressView, our clearance can be
revoked if postmarketing data demonstrates safety issues or lack of
effectiveness. More generally, we cannot assure you that the FDA will ever
grant 510(k) clearance or premarket approval for any additional products we
propose to market. If the FDA withdraws or refuses to grant clearances or
approvals, we will be unable to market such products in the U.S.


                                       16
<PAGE>

Modifications to our marketed devices may require new 510(k) clearances or PMA
approvals or require us to cease marketing or recall the modified devices until
such clearances or approvals are obtained.

   Any modification to an FDA-cleared device that could significantly affect
its safety or effectiveness, or that would constitute a major change in its
intended use, requires a new FDA 510(k) clearance or possibly PMA approval. The
FDA requires every manufacturer to make this determination in the first
instance, but the FDA can review any such decision. We have modified aspects of
In Charge, Duet and ExpressView, but we believe that new 510(k) clearances are
not required. We may modify future products after they have received clearance
or approval, and, in appropriate circumstances, we may determine that new
clearance or approval is unnecessary. We cannot assure you that the FDA would
agree with any of our decisions not to seek new clearance or approval. If the
FDA requires us to seek 510(k) clearance or PMA approval for any modification
to a previously cleared product, we also may be required to cease marketing or
recall the modified device until we obtain such clearance or approval. Also, in
such circumstances, we may be subject to significant regulatory fines or
penalties.

Complying with FDA and other regulations is an expensive and time-consuming
process, and any failure to comply could result in substantial penalties.

   Our products are medical devices that are subject to extensive regulation.
FDA regulations are wide-ranging and govern, among other things, product
design, development, manufacture and testing, labeling, storage, premarket
clearance or approval, advertising and promotion, and sales and distribution.
Noncompliance with applicable regulatory requirements can result in enforcement
action which may include recalling products, ceasing product marketing, paying
significant fines and penalties, and similar FDA actions which could limit
product sales, delay product shipment, and adversely affect our profitability.

   Sales of our products outside the U.S. are subject to foreign regulatory
requirements that vary from country to country. The time required to obtain
approvals from foreign countries may be longer than that required for FDA
clearance or approval, and requirements for foreign licensing may differ from
FDA requirements.

We are substantially dependent on one distributor for the sale of Duet, and in
the event this distributor does not perform satisfactorily, Duet sales and our
revenues and growth will be harmed.

   We have entered into a distribution agreement with PSS World Medical for
U.S. distribution of Duet. This agreement is exclusive through August 2002 and,
accordingly, we will be dependent on PSS for Duet sales. Although the
distribution agreement does provide for minimum sales commitments, our only
recourse if PSS does not meet these sales levels is to terminate this
agreement. If they fail to adequately support Duet, sales of Duet could fail to
grow or could decline. In addition, PSS may terminate the distribution
agreement upon specified notice. If this agreement was terminated, we would
have to make alternative arrangements to support Duet sales and marketing and
would likely lose sales until we either commenced marketing Duet on our own or
entered into arrangements with a new distributor.

We may be subject to costly and time-consuming product liability actions.

   Since our products are designed to be used by patients and health care
providers themselves, we may be subject to product liability lawsuits. We have
not been subject to any product liability claims; however, any product
liability claim brought against us, with or without merit, could result in the
increase of our product liability insurance rates or the inability to secure
coverage in the future. In addition, our insurance may not be adequate to cover
damages that we are required to pay. Finally, even a meritless or unsuccessful
product liability claim could be time consuming and expensive to defend and
could result in the diversion of management's attention.


                                       17

Because we use biological and hazardous materials, we may be liable for
damages.

   Our activities involve the controlled use of potentially harmful biological
materials as well as hazardous materials and various chemical compounds. In
particular, we perform quality assurance activities internally that require us
to use human blood samples. Accordingly, there is a risk that our employees or
other personnel in our facility will be exposed to blood-borne pathogens. We
cannot completely eliminate the risk of accidental contamination or injury from
the use, storage, handling or disposal of blood and other hazardous materials.
In the event of contamination or injury, we could be held liable for damages
that result, and any liability of this kind could exceed our resources. We are
subject to federal, state and local laws and regulations governing the use,
storage, handling and disposal of these materials and specified waste products.
The cost of compliance with these laws and regulations could be significant.

Our stock price may fluctuate significantly and the value of your investment
may decline.

   Our stock price may fluctuate for a number of reasons, including:

  . the publication of results of outside studies;

  . our ability to successfully manufacture and sell our products;

  . announcements of technological or competitive developments by others;

  . announcements regarding patent litigation or the issuance of patents to
    us or our competitors;

  . regulatory developments regarding us or our competitors;

  . changes in reimbursement policies of Medicare or private payors that
    affect reimbursement for our products;

  . acquisitions or strategic alliances by us or our competitors;

  . quarterly fluctuations in our results of operations;

  . changes in estimates of our financial performance or changes in
    recommendations by securities analysts; and

  . general market conditions, particularly for medical technology companies.

   If our future quarterly operating results are below the expectations of
securities analysts or investors, the price of our common stock would likely
decline. Stock price fluctuations may be exaggerated if the trading volume of
our common stock is low. Securities class action litigation may be brought
against a company after a period of volatility in the market price of its
stock. Any securities litigation claims brought against us could result in
substantial expense and diversion of management's attention.

The concentration of ownership among our existing officers, directors and
principal stockholders may prevent other stockholders from influencing
significant corporate decisions.

   Following the completion of this offering, our executive officers, directors
and current stockholders with at least 5% of our stock will control
approximately       % of our outstanding common stock. If these officers,
directors and principal stockholders act together, they will be able to
influence significantly and possibly control matters requiring approval by our
stockholders, including approvals of amendments to our certificate of
incorporation, mergers, a sale of all or substantially all of our assets, or
other transactions requiring stockholder approval. These stockholders may be
able to control the election of our board of directors.

There is no prior public market for our common stock, and you may not be able
to sell your shares at or above the initial public offering price.

   Prior to this offering, there has been no public market for shares of our
common stock. An active, liquid trading market may not develop following
completion of this offering, or if developed, may not be maintained.

                                       18
<PAGE>

We will determine the initial public offering price for the shares through
negotiations between us and representatives of the underwriters. This price may
not be indicative of prices that will prevail later in the trading market. The
market price of our common stock may decline below the initial public offering
price, and you may not be able to resell your shares at or above the initial
public offering price.

We are subject to anti-takeover provisions in our certificate of incorporation,
bylaws and Delaware law that could delay or prevent an acquisition of our
company, even if the acquisition would be beneficial to you.

   Our certificate of incorporation, our bylaws and Delaware law could make it
more difficult for a third party to acquire us, even if doing so would be
beneficial to you. These provisions could discourage potential takeover
attempts and could adversely affect the market price of our common stock.
Because of these provisions, you might not be able to receive a premium on your
investment. Among other things, these provisions:

  . authorize our board of directors, without stockholder approval, to issue
    up to 5,000,000 shares of "blank check" preferred stock that could be
    issued by our board of directors to increase the number of outstanding
    shares and prevent a takeover attempt;

  . provide that only our Chairman, President or entire board of directors
    may call a special meeting of our stockholders and that our stockholders
    may not call special meetings;

  . prohibit stockholder action by written consent, requiring stockholder
    actions to be taken at stockholder meetings; and

  . establish advance notice requirements for nominations for election to our
    board of directors and for proposals to be acted upon at stockholder
    meetings.

   Any of the provisions described above could delay or make transactions
involving a change in control of us or our management more difficult.

Future sales of our common stock could cause our stock price to decline.

   The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of our common stock in the public market
after the closing of this offering, or the perception that these sales could
occur. Upon expiration of 180-day lockup agreements entered into in connection
with this offering, approximately 9.3 million shares of our common stock will
be eligible for immediate sale in the public markets. In addition to causing
our stock price to decline, sales of these shares could make it more difficult
for us to sell equity securities in the future at a time and price that we deem
appropriate. In addition, the market price of our common stock could decline if
we sell additional equity securities in connection with financings or
collaborative arrangements.

Your investment will be immediately and substantially diluted.

   We expect the initial public offering price to be substantially higher than
the net tangible book value per share of the common stock. Therefore, if you
purchase shares of our common stock in this offering, you will incur immediate
and substantial dilution in pro forma net tangible book value of $      per
share (based on an assumed initial public offering price of $     ). You may
incur additional dilution if the holders of outstanding options or warrants
exercise those options or warrants. Additional information regarding the
dilution to investors in this offering is included in this prospectus under the
heading "Dilution."

                                USE OF PROCEEDS

   The proceeds from the sale of              shares of common stock we are
offering are estimated to be approximately $       million (approximately
$        million if the underwriters' over-allotment option is exercised in
full), after deducting underwriting discounts and commissions and our estimated
offering expenses. We intend to use the net proceeds from this offering for
sales and marketing expenses including to expand our sales force for In Charge
and Duet, product enhancement and development, and for general corporate
purposes including working capital and capital expenditures. We may also use a
portion of the proceeds to acquire or invest in complementary businesses or
products or to obtain the right to use complementary technologies; however, we
have no present plans, agreements or commitments and are not currently engaged
in any negotiations with respect to any such transactions. Pending use of the
net proceeds for the above purposes, we intend to invest these funds in short-
term, interest-bearing, investment grade obligations.

                                DIVIDEND POLICY

   We have never paid cash dividends on our capital stock. We currently
anticipate retaining all of our future earnings for the expansion and operation
of our business and do not anticipate paying any cash dividends in the
foreseeable future.

    these warrants are not exercised as permitted by their terms, the aggregate
    net proceeds to us will be reduced.

(2) The pro forma as adjusted information also gives effect to the issuance and
    sale of the         shares of common stock offered by us in this offering
    at an assumed initial public offering price of $      per share, after
    deducting estimated underwriting discounts and commissions and estimated
    offering expenses payable by us.

(3) The outstanding share information excludes outstanding options to purchase
    a total of 1,595,066 shares of common stock at a weighted-average exercise
    price of $3.69 per share. The outstanding share information also excludes
    common stock warrants to purchase a total of 55,269 shares of common stock
    at a weighted-average exercise price of $7.00 per share.

                                    DILUTION

   Our net tangible book value as of June 30, 2000 was $2.3 million or $2.10
per share of common stock. Net tangible book value per share is determined by
dividing the net tangible book value (total tangible assets less total
liabilities) by the number of outstanding shares of common stock at that date.
Assuming the issuance and sale by us of 358,799 shares of Series F preferred
stock in October 2000, the conversion of all outstanding shares of preferred
stock into 8,018,686 shares of common stock as of the closing of this offering,
and the conversion of all outstanding common and preferred stock warrants into
901,101 shares of common stock as of the closing of this offering, our pro
forma net tangible book value as of June 30, 2000 would have been approximately
$13.2 million or $1.32 per share of common stock. Without taking into account
any other changes in pro forma net tangible book value other than the sale of
          shares of our common stock in this offering (after deducting
underwriting discounts and offering expenses), the pro forma net tangible book
value at June 30, 2000 would be $      million or $      per share. Upon the
completion of this offering, there will be an immediate increase in net
tangible book value to existing shareholders of $      per share and an
immediate dilution to new investors of $         per share. The following table
illustrates the per share dilution:

   The foregoing table assumes no exercise of the underwriters' over-allotment
option and no exercise of common stock options and warrants outstanding at June
30, 2000. As of October 16, 2000, there were options outstanding to purchase a
total of 1,595,066 shares of common stock at a weighted average exercise price
of $3.69 per share. As of October 16, 2000, there were warrants outstanding to
purchase a total of 19,547 shares of common stock at a weighted average
exercise price of $7.00 per share. To the extent that any of these options are
exercised, there will be further dilution to new investors.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

   You should read this discussion together with the financial statements and
other financial information included in this prospectus. Please refer to
"Special Note Regarding Forward-Looking Statements" and "Risk Factors".

Overview

   We are a medical technology company that develops, manufactures and markets
products for people with diabetes. Our products allow patients and health care
professionals to better monitor the effectiveness of treatment regimens and
make therapy changes to improve overall glucose control. From our inception in
1993 through 1997, our operations consisted primarily of various start-up
activities, including developing of our proprietary technology and testing
formats, conducting clinical studies, recruiting personnel, and raising capital
to fund operations.

   In January 1998, we began commercial shipment of our first product, Duet.
Duet is marketed to health care professionals through an exclusive distributor
serving the U.S. physician office market. In October 1999, we introduced In
Charge in selected regions of the U.S. In Charge is sold primarily to
wholesalers that serve national and regional retail pharmacy chains as well as
local pharmacies. Duet and In Charge each include a hand-held monitor that
performs our GlucoProtein test on a single-use disposable test strip. In
addition, they also measure blood glucose, on a separate test strip. Patients
can purchase the In Charge monitor and disposable test strips at their pharmacy
without a prescription. Our third product, ExpressView, was introduced in
December 1999. ExpressView uses the same monitor platform as In Charge, but
performs only the glucose test. ExpressView is sold primarily to mail-order
firms serving Medicare patients.

   We derive our revenues from the sale of monitors and disposable test strips.
The test strips provide us with a recurring revenue stream. The sales of the
test strips will increase as a percentage of our total revenues as the base of
installed monitors increases in both the health care professional and consumer
markets.

   We recognize revenue when all of the following criteria have been met:

   . persuasive evidence of an arrangement exists between us and our customer;

   . we have delivered our product to our customer;

   . our price for the products sold is fixed or determinable; and

   . collectibility of the sales price is reasonably assured.

We offer certain rights of return to our customers. Since we lack sufficient
history to make reliable accurate estimates of product returns at the time of
shipment, we defer the recognition of revenue until customers' return rights
have expired. In the case of sales to distributors, this occurs when the
distributors have sold the product to their customers. In the case of direct
sales to medical equipment suppliers and end users, this generally occurs 30
days after products have been shipped.

   Manufacturing costs for our proprietary disposable test strips consist of
raw materials, such as membranes, chemicals, and plastic parts, direct labor to
assemble the strips, general production overhead, and royalties we pay on
licensed technology used in the design of the GlucoProtein test strip. Cost of
goods sold also includes the cost of purchasing assembled monitors that are
manufactured in Germany exclusively for us. Sales and marketing expenses relate
primarily to our sales force, our customer service function, corporate staff,
advertising and promotions. General and administrative expenses consist
primarily of the cost of corporate operations and related personnel, legal,
accounting, information systems and other general operating expenses. Research
and development expenses consist primarily of personnel cost and general
laboratory supplies.

                                       25
<PAGE>

   In the second and third quarters of 1999, we consolidated the distribution
of Duet through one wholesaler, PSS, and terminated distribution arrangements
with all of our other distributors in order to be able to better manage our
distribution network. We also discontinued the sale of Duet in retail channels
and concentrated solely on the U.S. physician office market. Our distribution
agreement with PSS is exclusive through August 2002 and includes minimum sales
commitments. As part of this change in business strategy, in June 1999 we
terminated some of our management team and other employees. This allowed us to
reduce our operating costs until In Charge was introduced and rolled out. The
severance and other employee-related charges associated with these terminations
totaled $810,000 and were recorded in June 1999.

Results of Operations

Six months ended June 30, 1999 and 2000

 Revenues

   Revenues increased by 139% from $756,000 during the six months ended June
30, 1999 to $1.8 million during the six months ended June 30, 2000. The
increase in revenues resulted primarily from the commercial launch of two new
products, In Charge and ExpressView, during the fourth quarter of 1999.
Revenues from In Charge and the related test strips and revenues from
ExpressView and the related test strips totaled $372,000 and $576,000,
respectively, during the six months ended June 30, 2000. In addition, revenues
from Duet increased from $756,000 in the six months ended June 30, 1999 to
$855,000 in the six months ended June 30, 2000. As of June 30, 2000, we had
shipped $585,000 of products which, based on our revenue recognition policy,
had not yet been recorded as revenues.

 Gross (loss) profit

   We improved from a gross loss of 34% of revenues during the first six months
of 1999, to a gross profit of 7% of revenues during the six months ended June
30, 2000. The improvement was primarily due to increased production of test
strips, which resulted in reduced direct labor costs; increased purchases of
monitors, which resulted in a lower cost per unit from our supplier; and
decreased cost of printed packaging material. In addition, in June 1999, we
terminated our agreement with our manufacturer of Duet monitors. We purchased
$615,000 of monitors and recorded an inventory reserve for excess quantities of
$182,000 during the six months ended June 30, 1999. We expect that our gross
profit will continue to increase in the foreseeable future, primarily as a
result of economies of scale achieved due to our increased volume of
production.

 Selling and marketing expenses

   Selling and marketing expenses decreased 5% from $2.3 million during the six
months ended June 30, 1999 to $2.1 million during the six months ended June 30,
2000. The decrease is primarily due to the decrease of $342,000 in compensation
and related costs associated with a reduction in our sales force during 1999.
This decrease was partially offset by the higher marketing costs of $222,000
related to the commercial launch of In Charge. We intend to significantly
expand our sales and marketing teams in order to penetrate more retail markets.
As a result, we expect that selling and marketing expenses will increase as a
percentage of revenues through at least 2001.

 General and administrative expenses

   General and administrative expenses decreased 47% from $2.2 million during
the six months ended June 30, 1999 to $1.1 million during the six months ended
June 30, 2000. The decrease resulted primarily from a decrease in personnel
expenses of $810,000 related largely to employee terminations in June 1999.

                                       26

 Research and development expenses

   Research and development expenses decreased 82% from $1.1 million during the
six months ended June 30, 1999 to $208,000 during the six months ended June 30,
2000. The decrease is primarily due to the winding down of development and
regulatory expenses of InCharge and ExpressView. The major components of this
decrease include a decrease in personnel costs of $200,000 related primarily to
employee terminations in June 1999; a decrease of $213,000 related to the
termination of a co-development agreement during the six months ended June 30,
1999; and a decrease in costs of $188,000 resulting from a transition to
manufacturing following regulatory approval of InCharge and ExpressView. We
intend to continue to develop additional products for the diabetes market as
well as improve existing products. As a result, research and development
expenses are expected to increase on an absolute basis for the foreseeable
future.

 Stock-based compensation

   In connection with the grant of stock options to employees, directors and
consultants, we recorded unearned stock-based compensation as a component of
stockholders' deficit and are amortizing the recorded amounts as charges to
operations over the vesting periods of the options using an accelerated method.
We recorded amortization of stock-based compensation of $641,000 during the six
month period ending June 30, 1999 as compared to $1.4 million for the same
period in 2000. Our total unearned stock-based compensation at June 30, 2000
was $3.2 million, which will be amortized over the vesting period of the
respective options.

 Interest income

   Interest income decreased 36% from $190,000 during the six months ended June
30, 1999 to $121,000 during the six months ended June 30, 2000. The decrease
resulted from lower average cash balances during the six months ended June 30,
2000, partially offset by higher interest rates during this period.

 Other income

   Other income increased 106% from $97,000 in the six months ended June 30,
1999 to $200,000 in the six months ended June 30, 2000. Other income for both
these periods relates to the licensing of certain technology to a third party.

 Income taxes

   As a result of our net losses as well as the full valuation allowance
recorded against our deferred tax assets, we did not incur any income tax
expense in either the six months ended June 30, 1999 or the six months ended
June 30, 2000.

Years ended December 31, 1998 and 1999

 Revenues

   Revenues decreased 16% from $2.5 million during 1998 to $2.1 million in
1999. The decrease resulted primarily from lower sales of Duet in retail
pharmacies, as we prepared to replace it with InCharge, and from the
termination of our previously existing distribution agreements during the
transition to an exclusive distribution agreement with PSS in July 1999.

 Gross (loss) profit

   Gross loss decreased from 17% of revenues during 1998 to 5% of revenues in
1999. This reduction was due primarily to improved production yields resulting
in less manufacturing waste, improved efficiencies in certain manufacturing
processes during our second year of production. In addition, in June 1999, we
terminated our agreement with our manufacturer of Duet monitors. We purchased
approximately $615,000 of monitors and recorded an inventory reserve for excess
quantities of $182,000 during 1999.

                                       27
<PAGE>

 Selling and marketing expenses

   Selling and marketing expenses decreased 34% from $6.3 million in 1998 to
$4.2 million in 1999. The decrease resulted primarily from a decrease in
expenses related to the termination of a contract with an outside sales
organization for the sale of Duet and a decrease in marketing expenses related
to the commercial launch of Duet, which were partially offset by marketing
expenses related to the commercial launch of In Charge in late 1999.

 General and administrative expenses

   General and administrative expenses increased 39% from $2.4 million in 1998
to $3.3 million 1999. Lower personnel costs resulting primarily from employee
terminations in June 1999 were partially offset by increased facility costs
following our move to a new facility in December 1998.

 Research and development expenses

   Research and development expenses decreased 33% from $2.1 million in 1998
to $1.4 million in 1999. The decrease resulted primarily from lower personnel
costs resulting largely from employee terminations in June 1999 and lower
regulatory expenses following our 510(k) submission to the FDA for In Charge
in early 1999.

 Stock-based compensation

   We amortized unearned stock-based compensation of $700,000 in 1998 compared
to $1.1 million in 1999.

 Interest income

   Interest income decreased 22% from $472,000 during 1998 to $368,000 during
1999. The decrease resulted from lower average cash balances during 1999.

 Interest expense

   Interest expense increased 132% from $60,000 during 1998 to $139,000 during
1999. The increase resulted from higher average borrowings under a credit
facility in 1999.

 Other income

   Other income during 1999 consisted of $100,000 related to the licensing of
certain technology to a third party.

 Income taxes

   No income tax expense was recorded during 1998 or 1999 due to our
cumulative net losses as well as the full valuation allowance recorded against
our deferred tax assets of $8.3 million and $11.6 million, respectively, since
it is more likely than not that such assets will not be realized.

Years ended December 31, 1997 and 1998

 Revenues

   We had no revenues until the launch of Duet in January 1998.

 Gross (loss) profit

   Gross loss of $430,000 in 1998 was primarily due to costs associated with
initiating production of Duet and the related inefficiencies of the
manufacturing processes during our first year of production.

 Selling and marketing expenses

   Selling and marketing expenses increased from $828,000 during 1997 to $6.3
million during 1998. The increase resulted from the marketing and sales
expenses related to the commercial launch of Duet, including the establishment
of a sales force, distribution channels and various marketing campaigns.

                                      28
<PAGE>

 General and administrative expenses

   General and administrative expenses increased from $1.8 million during 1997
to $2.4 million during 1998. The increase resulted primarily from our hiring of
executive, administrative, accounting and information systems personnel to
support the commercial launch of Duet.

 Research and development expenses

   Research and development expenses decreased from $2.6 million during 1997 to
$2.1 million during 1998. The decrease resulted primarily from lower
development expenses for Duet, which was launched in January 1998.

 Stock-based compensation

   We recorded amortization of stock-based compensation of $290,000 for 1997
compared to $700,000 for 1998.

 Interest income

   Interest income increased from $326,000 during 1997 to $472,000 during 1998.
The increase resulted from higher average cash balances during 1998.

 Income taxes

   No income tax expense was recorded during 1997 or 1998 due to our cumulative
net losses as well as the full valuation allowance recorded against our
deferred tax assets since it is more likely than not that such assets will not
be realized.

Liquidity and Capital Resources

   Since inception, we have funded our operations and capital investments from
the private sale of preferred stock and preferred stock warrants, including
Series F preferred stock and warrants in October 2000, totaling $39.9 million
(net of financing expenses), a $750,000 credit facility with a bank during 1997
and a credit facility from a bank initiated during 1998 and amended in 1999,
which included a $2 million term loan, a $500,000 equipment line of credit and
a $1 million accounts receivable line of credit. At June 30, 2000, $1.2 million
remained outstanding under the term loan. This debt is being paid off under an
arrangement maturing in March 2003 and is collateralized by all of the assets
of the Company. The promissory note evidencing the term loan provides for
monthly principal payments of $35,155. Interest is payable monthly at the
bank's prime rate plus 0.5% (10% as of June 30, 2000). The $500,000 line of
credit is available through March 21, 2001 for equipment purchases. The
interest rate for advances on the equipment line of credit is the same as the
term loan. Interest only is due monthly through September 21, 2000, and the
outstanding principal balance is payable in 30 equal payments of principal plus
accrued interest beginning October 21, 2000. At June 30, 2000, $500,000 was
outstanding on the equipment line of credit. The interest rate for advances on
the accounts receivable line of credit is the bank's prime rate, and advances
are payable upon the earlier of March 21, 2000 or a demand from the bank. We
took no advances on the accounts receivable line of credit during 1999 or the
six months ended June 30, 2000. At October 16, 2000 we were in default of
certain covenants contained in the term loan and equipment line of credit
agreements noted above, as amended in October 2000. As a result, the entire
remaining principal balances of the bank credit facilities are due on demand
and have been classified as current liabilities. At June 30, 2000, we had
$493,000 in working capital and our primary source of liquidity was $1.7
million in cash and cash equivalents.

   In August and September 2000, we entered into convertible promissory notes
with an aggregate principal amount of $2,500,000. The notes provided for
interest payments at 8% per annum. In addition, the holders of the notes
received warrants to purchase 17,861 shares of Series F preferred stock at a
purchase price of $14 per share. The fair value of the warrants on the date of
issuance was estimated to be $379,000 and was recorded as

                                       29
<PAGE>

debt issuance costs and amortized to interest expense over the life of the
notes. In October 2000, we issued 178,569 shares of Series F redeemable
convertible preferred stock at a price of $14 per share for total gross
proceeds of $2,500,000. Upon the completion of the Series F preferred stock
financing, the outstanding convertible promissory notes and unpaid accrued
interest thereon automatically converted into 180,230 shares of Series F
preferred stock. We will record a charge for the beneficial conversion feature
embedded in these securities in October 2000. The value of the beneficial
conversion feature was measured using its intrinsic value, i.e., the excess of
the aggregate fair value of the common stock into which the Series F preferred
stock is convertible over the proceeds allocated to the security. The intrinsic
value of the beneficial conversion feature of approximately $5.8 million
exceeded the proceeds allocated to the Series F preferred stock of
approximately $4.6 million; therefore, we limited recognition of the beneficial
conversion feature to the approximately $4.6 million proceeds allocated to the
Series F preferred stock. We accreted the entire amount of the beneficial
conversion feature at the date of issuance because the Series F preferred stock
is immediately convertible.

   Net cash used in operating activities was $4.7 million, $10.1 million, $8.2
million and $3.4 million in 1997, 1998, 1999 and the six months ended June 30,
2000, respectively. Net cash used in each period is primarily due to our net
losses and, in the six months ended June 30, 2000, an increase in accounts
payable.

   Net cash used in investing activities was $6.2 million in 1997. Net cash
provided by investing activities was $3.9 million in 1998. Net cash used in
investing activities was $660,000 in 1999 and $226,000 during the six months
ended June 30, 2000, respectively. During 1997, the net cash used included
primarily the purchase of short-term investments of $4.9 million, fixed assets
of $805,000 and restricted cash of $500,000 to collateralize a credit facility
with a bank. During 1998, the short-term investments were sold to provide funds
for the Company's operations. The funds were partially offset by the purchase
of $1.5 million of fixed assets. During 1999 and the six months ended June 30,
2000, net cash used included the purchase of fixed assets totaling $660,000 and
$226,000, respectively.

   Net cash provided by financing activities was $12.2 million, $4.6 million,
$9.5 million and $297,000 in 1997, 1998, 1999 and the six months ended June 30,
2000, respectively. During 1997, the net cash provided included the sale of
preferred stock for net proceeds of $11.7 million and borrowings of $497,000.
During 1998, the net cash provided included the sale of preferred stock for net
proceeds of $3.5 million and borrowings of $1.6 million. The cash provided from
these sources was partially offset by the repayment of the $497,000 borrowed
under a credit facility with a bank in 1998. During 1999, the net cash provided
included the sale of preferred stock for net proceeds of $9.7 million and
borrowings of $128,000. The cash provided from these sources was partially
offset by the repayment of $316,000 on a bank credit facility. During the six
months ended June 30, 2000, net cash provided was primarily due to borrowings
of $500,000 partially offset by repayments of $211,000 on a bank credit
facility.

   We will expend substantial funds in the future for research and development,
clinical testing, capital expenditures, and the manufacturing, marketing, and
sale of our products. We cannot accurately predict the timing and amount of
these expenses, which depend on several factors, including:

  . the effectiveness of our various planned sales and marketing activities;

  . the progress of our research and development efforts related to our
    second generation products;

  . the continued successful results of our current product lines; and

  . competing technological and market developments.

   We believe that cash from operations, our existing cash and cash equivalents
and net proceeds from the sale of our Series F preferred stock in October 2000
and the net proceeds from this offering will be sufficient to meet our
anticipated cash requirements for at least the next 12 months. If we do not
sell the shares in this offering, we would need to generate significant
additional revenues or raise additional capital in order to meet our
anticipated cash requirements for the next 12 months. The failure to generate
significant additional revenues or raise additional capital will have a
significant adverse impact on our business and operations. We cannot assure you
that additional financing will be available on a timely basis on terms
acceptable to us, or that such financing will not be dilutive to our
stockholders.

Impact of Inflation

   Inflation generally affects us by increasing our cost of labor, equipment
and production supplies. We do not believe that the relatively low rates of
inflation experienced in the U.S. in recent years has had any material effect
on our business.

Interest Rate and Foreign Currency Risk

   We are subject to changes in the prime interest rate for our term loan
arrangement, which accrues interest at the bank's prime rate plus 0.5%. To
minimize the market rate risk of our cash we have in the past and will continue
to invest primarily in U.S. government securities, AAA-rated corporate bonds
and A-1/P-1 rated commercial paper. We do not utilize derivative financial
instruments, derivative commodity instruments or other market risk sensitive
instruments, positions or transactions in any material fashion.

   We have a contract with a German supplier for our In Charge and ExpressView
monitors. To minimize the effect of changes in the exchange rate, we have
negotiated a sliding scale pricing model based on the exchange rate. Since we
began purchasing the monitor from the supplier in July 1999, the exchange rate
has increased about 12%. Although the change in the exchange rate has been in
our favor, it has not had a material effect on our business or results of
operations.

Recently Issued Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board, or FASB, issued
Statement of Financial Accounting Standards 133, or SFAS 133, "Accounting for
Derivative Instruments and Hedging Activities," which establishes accounting
and reporting standards for derivative instruments and hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities on the balance sheet and measure those instruments at fair value.
SFAS 133 as amended by SFAS 137, "Accounting for Derivative Instruments and
Hedging Activities-Deferral of the Effective Date of SFAS 133," an amendment of
SFAS 133, is effective for fiscal years beginning after June 15, 2000. To date,
we have not engaged in derivative or hedging activities.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin 101, or SAB 101 "Revenue Recognition," which provides
guidance on the recognition, presentation and disclosure of revenue in
financial statements filed with the SEC. SAB 101 outlines the basic criteria
that must be met to recognize revenue and provides guidance for disclosure
related to revenue recognition policies. The adoption of the principles of SAB
101 has not had a significant impact on our financial statements.

   In March 2000, the FASB issued FASB Interpretation No. 44, called FIN 44
"Accounting for Certain Transactions Involving Stock Compensation, an
Interpretation of APB 25." The Interpretation clarifies:

  .the definition of an employee for purposes of applying Opinion 25;

  . the criteria for determining whether a stock option or award plan
    qualifies as a non-compensatory plan;

  . the accounting consequences of various modifications to the terms of a
    previously fixed stock option or award; and

  . the accounting for an exchange of stock compensation awards in a business
    combination.

FIN 44 became effective on July 1, 2000, with certain provisions effective
earlier. We do not expect FIN 44 to have a significant impact on our financial
statements.

   In August 2000, the FASB Emerging Issues Task Force, or EITF, issued EITF
00-14, "Accounting for Certain Sales Incentives," which addresses the
recognition, measurement, and classification for sales incentives offered
voluntarily by vendors without charge. We believe that our current policy for
accounting for sales incentives is in compliance with EITF 00-14.

Background

   Diabetes is a chronic, progressively debilitating disease in which the human
body loses its ability to maintain a normal level of glucose in the
bloodstream. In the body's normal digestive process, carbohydrates in food are
broken down into glucose, which is then circulated in the bloodstream and
converted into energy. Glucose levels are naturally controlled by insulin, a
hormone produced by the pancreas. Diabetes develops when pancreatic cells
produce insufficient amounts of insulin or when the body loses the ability to
properly respond to insulin. If left untreated, diabetes often results in
severe complications that include kidney failure, blindness, amputation and
cardiac disease. Diabetes is the fourth leading cause of death by disease in
the U.S. with an annual cost of treatment of the disease and related
complications approximately $100 billion, or 10% of total U.S. health care
spending. In the U.S. there are an estimated 10.3 million individuals diagnosed
with diabetes, as well as an estimated six million people who have not yet been
diagnosed. The ADA estimates that approximately 800,000 new cases of diabetes
were diagnosed in 1999.

   Diabetes is generally classified into two types. Type 1 diabetes, formerly
called insulin-dependent or juvenile-onset diabetes, is the more severe form of
the disease in which the pancreas loses the ability to produce insulin. As a
result, Type 1 patients require life-long daily insulin injections to control
their blood glucose levels. In the U.S. about one million individuals, or
approximately 10% of the identified population of diabetes patients, have been
diagnosed with Type 1 diabetes. Type 2 diabetes, formerly called non-insulin
dependent or adult-onset diabetes, comprises the vast majority of the diagnosed
diabetes population. There are estimated to be currently more than nine million
Type 2 patients. Type 2 diabetes is generally characterized by a combination of
insufficient insulin production by the pancreas and the body's insufficient
response to insulin, resulting in high levels of blood glucose.

   Diabetes is not curable but it is manageable. Ineffective management can
result in serious complications. For example, diabetic eye disease is the most
common cause of blindness in working age adults, with an estimated 24,000
diabetic patients becoming blind each year. In addition, more than 50% of lower
limb amputations in the U.S. occur among people with diabetes, resulting in an
estimated 80,000 amputations performed each year. The goal of diabetes
management is to continuously maintain a blood glucose level within a normal
range in order to avoid or minimize these complications. A generally accepted
marker of overall glucose control is the glycated protein hemoglobin A1c,
commonly referred to as HbA1c. In 1993, the Diabetes Control and Complications
Trial, or DCCT, sponsored by the National Institutes of Health, established
that a 10% reduction in an average patient's HbA1c level resulted in a 45%
reduction in the risk of blindness, a 40% reduction in the risk of loss of a
limb by amputation and a 30% reduction in the risk of kidney damage.

   Blood glucose monitoring is critical to effective management of diabetes.
Type 1 patients typically manage their blood glucose levels with daily
monitoring and insulin injections. In contrast, Type 2 diabetes ranges widely
in severity and patients have a complex menu of treatment options. There are
currently over 250 therapeutic regimens, made up of varying combinations of
diet and exercise, drugs and, in some cases, insulin injections. Because of
these various treatment options, patients with Type 2 diabetes also require
blood glucose monitoring in order to measure the effectiveness of their
therapy. The following diagram depicts an understanding of the typical
progression in treatment of a given patient with Type 2 diabetes over several
years:

Blood Glucose Monitoring

   The goal of glucose monitoring is to avoid the complications of diabetes by
allowing patients and their health care providers to determine a treatment
regimen, to monitor the effectiveness of the regimen and to alter it as needed
for better overall glucose control. There are various testing methods to
monitor glucose levels. These tests either measure the amount of glucose in the
patient's blood at a particular point in time, or measure the level of a
glycated protein to determine the average amount of glucose present within the
patient's blood over a period of time.

   Point-In-Time Blood Glucose Measurements. A patient's glucose level may be
measured directly with a non-prescription test. The test can be performed in a
physician's office or by a patient at home. Typically, a patient must prick a
finger and then apply a drop of blood to a test strip. The test strip is then
analyzed by a commercially available monitor that displays the result,
providing a "snapshot" of the patient's glucose level at the moment that the
test is performed. The U.S. market for home point-in-time blood glucose tests
was $1.1 billion in 1999, compared to $760 million in 1996, an annual
compounded growth rate of 13%. It is estimated that in 1999 there were over two
billion point-in-time blood glucose tests performed in the U.S.

   Average Blood Glucose Measurements. A patient's average blood glucose level
over a period of time, as opposed to at a point-in-time, may be determined by
measuring the level of glycated proteins in the patient's bloodstream. Glycated
proteins are formed when glucose attaches to protein molecules. High levels of
blood glucose lead to high levels of glycated proteins in the bloodstream,
where the proteins remain until they are metabolized by the body. The two
glycated proteins most commonly measured in these tests are HbA1c, which
results from glucose attaching to red blood cells, and fructosamine, which
results from glucose attaching to other circulating serum proteins. Because red
blood cells have a circulating lifespan within the bloodstream of approximately
90-120 days, an HbA1c measurement represents the average level of glucose
present within the patient's bloodstream over approximately the preceding three
months. In contrast, since circulating serum proteins remain in the bloodstream
for approximately 20 days, a fructosamine measurement indicates the average
level of glucose present in the patient's blood over the prior two to three
weeks.

   The following table summarizes the currently available glucose monitoring
techniques:


<TABLE>
<CAPTION>

Limitations of Conventional Glucose Monitoring Techniques

   Point-In-Time Blood Glucose Measurements. Patients with Type 1 diabetes can
use point-in-time blood glucose test results to determine the appropriate
timing and amount of insulin injections. However, the test provides a snapshot
of the patient's glucose level during only one minute of the 1,440 minutes in
an entire day. As a result, the point-in-time test cannot measure blood glucose
fluctuations over time. Blood glucose levels in patients with diabetes can
fluctuate dramatically during each day based on numerous factors, including
diet, exercise and overall health. This problem is magnified if patients do not
perform the recommended number of daily tests. However, even testing four or
five times can only give results from four or five minutes of the 1,440-minute
day. Moreover, persons with Type 2 diabetes who do not need insulin injections
generally are infrequent testers since their treatment regimens are not likely
to be modified by data from point-in-time glucose testing. Type 2 patients
typically do not perform multiple point-in-time glucose tests per day, because
the testing can be inconvenient, frequent collection of blood samples can be
painful, and the aggregate cost of testing can be expensive.

   Average Blood Glucose Measurements. Measuring levels of glycated proteins
such as HbA1c and fructosamine is a better indicator of a patient's average
blood glucose levels than point-in-time glucose testing.

                                       33
<PAGE>

The HbA1c test was the first test for average blood glucose levels, but some
characteristics of HbA1c testing have limited its potential value. Because the
HbA1c measurement represents an average level over the preceding three months,
its use in therapy guidance and compliance is limited. This quarterly timeframe
makes it difficult for patients to detect weekly changes in glucose control,
reducing the ability of physicians to make timely therapy changes. In addition,
patients are less likely to accurately remember behavior patterns over specific
periods within a three month timeframe. HbA1c tests have also historically been
laboratory-based tests, which makes them inconvenient for patients because of
the difficulties of going to a lab each time a test is necessary. Laboratory-
based tests are also less useful for physicians since the test results are not
available during a patient's visit, and thus cannot be easily incorporated into
treatment modification or patient feedback. Fructosamine testing has
historically had similar limitations, since it too has been generally
laboratory-based.

   As a result of these limitations, prior to the introduction of our products,
patients and physicians have not had access to a home-based test to effectively
monitor overall glucose control that provides timely feedback and allows for
rapid therapy adjustment.

Our Solution

   We have developed and commercialized our GlucoProtein(R) test, the only
over-the-counter home-based test for fructosamine. This proprietary
GlucoProtein test addresses the limitations of existing testing methods by
enabling persons with diabetes to perform glycated protein testing at home
rather than wait for the results from laboratory-based tests. In addition,
because our GlucoProtein test analyzes fructosamine rather than HbA1c, it
measures the patient's average blood glucose level over the prior two to three
weeks. Understanding average glucose levels during the recent past enables
patients and their health care professionals to more meaningfully analyze past
behaviors and treatment regimens and alter them as necessary. For these
reasons, we believe that our test enables patients to take a more active role
in their therapy. Additionally, In Charge and Duet combine our GlucoProtein
test with a point-in-time blood glucose test, providing users with the ability
to measure either blood glucose levels at that moment as well as their average
over the prior few weeks. This combination gives them an ongoing option to
obtain different types of data as they or their health care provider see fit.

   In December 1999, a clinical trial demonstrated that a combination of once-
weekly GlucoProtein testing and regular point-in-time blood glucose testing
resulted in a greater reduction of HbA1c levels in patients as compared to a
regimen of point-in-time glucose testing alone. The average person without
diabetes has an HbA1c level of 4% to 6%, while the average person with diabetes
has an HbA1c level of 9% or 10%. Doctors become concerned when a patient's
HbA1c level is 8% or above. In this clinical trial, 25 patients with HbA1c
levels above 8% were randomized into two groups. One of the groups was
instructed to perform point-in-time blood glucose testing up to four times per
day, but no GlucoProtein testing at all. The other group was instructed to
perform point-in-time glucose testing up to four times per day in addition to a
once-weekly GlucoProtein test. Both groups were instructed to report to the
clinician if they had indications of poor glucose control to receive the proper
treatment. Both groups were also asked to return after three months at which
time their HbA1c levels were tested again. In the test group using both point-
in-time blood glucose tests and our GlucoProtein tests, the average HbA1c
levels dropped by 13.0%, while the average HbA1c levels of a test group using
only point-in-time blood glucose tests dropped by only 3.2%. The results are
summarized below:

<TABLE>
<CAPTION>
                                  Starting Ending
                                   HbA1c   HbA1c  % Drop  Significance

     <S>                          <C>      <C>    <C>    <C>
     Glucose & GlucoProtein test   9.2      8.0   13.0%     P< 0.0001
     Glucose testing only          9.4      9.1    3.2%  Not Significant
</TABLE>

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

   The probability that the observed drop in HbA1c levels did not occur by
chance when using glucose testing together with GlucoProtein testing was
statistically significant at the 99.99% or greater level, or what is referred
to as p <0.0001. This means that by applying widely-used statistical methods,
the chance that these

                                       34
<PAGE>

results could have occurred by accident is less than 1 in 10,000. On the other
hand, the drop in HbA1c levels observable with glucose only testing was not
statistically significant.

   The difference in the percentage declines in each group's average HbA1c
levels is particularly meaningful considering that the DCCT indicated that for
each 10% reduction in HbA1c levels in a diabetes patient, that patient will
have a 45% reduction in the risk of losing eyesight, a 40% reduction in the
risk of losing a limb by amputation and a 30% reduction in the risk of kidney
damage.

Our Strategy

   Our goal is to become the leader in the development and commercialization of
diabetes products that improve medical outcomes by better managing patients'
overall glucose control. There are four basic elements to our business
strategy:

   Establish GlucoProtein Home Testing as the Standard of Care for Management
of Type 2 Diabetes. We will sponsor additional clinical trials to further
support that the use of GlucoProtein home testing improves medical outcomes. We
intend to present the results of these studies to key medical organizations
such as the ADA to facilitate adoption of GlucoProtein home testing as a
standard of care. We will publicize the results of these trials to facilitate
the continued adoption of GlucoProtein and In Charge by managed care and health
care payors. We also intend to conduct studies of additional patient
populations, such as children, to expand the use and labeling claims for
GlucoProtein home testing.

   Aggressively Pursue Nationwide Sales and Marketing Efforts. We launched In
Charge on a regional basis in October 1999. Based on the success of this
launch, we plan to aggressively pursue nationwide sales and marketing efforts.
We will build a nationwide sales force, which will promote In Charge to
diabetes-focused physicians, diabetes educators, respected opinion leaders and
pharmacists. In addition, we will promote Duet to physicians because we believe
doctors who use Duet in their office practice will recommend that their
patients use In Charge at home. In parallel, we plan to market In Charge
directly to patients.

   Enhance Technology Leadership Position. Initially, we will focus on
improving our existing products to meet the future needs of the consumer
market. We also plan to develop new products to meet changing consumer
requirements and to measure additional disease parameters common in patients
with diabetes. We continually examine opportunities to acquire or in-license
new products that improve diabetes treatment or therapy management. We target
pharmaceutical companies with diabetes drugs on the market or in development
that can benefit from fructosamine testing as a clinical research tool or could
incorporate fructosamine testing into the drug regimen. Bristol-Myers Squibb,
for example, has incorporated In Charge into several clinical trials to support
the continued development of one of its drugs for the treatment of Type 2
diabetes.

   Broaden Reimbursement Coverage. To accelerate health care payor acceptance
of In Charge, we combined GlucoProtein test strips and glucose test strips in
the same package. We have successfully obtained reimbursement from a number of
managed care organizations and we will continue to target additional managed
care organizations to obtain reimbursement.

Our Products

   We currently market three FDA-cleared products: In Charge, Duet and
ExpressView. Each product consists of a hand-held monitoring device that uses
single-use disposable strips to perform specific tests. It is estimated that
patients use their monitoring device for an average of three years and perform
tests at regular intervals during that period. We target each of our products
to a distinct segment of the diabetes management market.

                                       35

 In Charge(TM) Diabetes Control System--For Home Use

   We launched our first consumer product, In Charge, in October 1999. This
system performs both GlucoProtein and blood glucose tests. In Charge has three
components: a GlucoProtein test strip, a glucose test strip and a hand-held
electronic monitor. We package the GlucoProtein test strips either with glucose
test strips or separately for patients wishing to perform only GlucoProtein
testing. We recommend that patients perform a GlucoProtein test weekly. Glucose
testing frequency is based on the direction of the patient's health care
professional.

   The GlucoProtein test strip is multilayered and contains a proprietary
combination of membranes and chemicals. The strip incorporates our expertise in
blood separation technology and is manufactured using our patented process. The
different layers on the strip, which we call reaction layers, are crucial to
obtaining accurate results. The test strip reacts by color changes as the
chemicals act upon a blood sample, and varying degrees of color generation
indicate different concentrations of fructosamine.

[ARTWORK APPEARS HERE]

Schematic of test strip with relevant parts of the artwork labelled
"GlucoProtein test strip," "Blood" and "Blood Separation and Reaction Layers."

   Our In Charge glucose test strip is also manufactured using our patented
technology. Our glucose strip measures results in as little as five seconds.
The rapid performance of the In Charge glucose test strip is the result of
proprietary features built into the strip itself and proprietary algorithms
used in the monitor.

   The In Charge monitor is a lightweight hand-held monitor that detects and
reads concentrations of glucose from a glucose test strip and fructosamine from
a GlucoProtein test strip. The In Charge monitor provides a digital read-out
number and is designed to interpret the results for the patient by
characterizing the fructosamine concentrations as "good," "intermediate" or
"poor" overall glucose control, which helps patients understand the results and
take corrective action as necessary. The GlucoProtein test takes approximately
four minutes to obtain results. In Charge and Duet are the only products
available that measure both blood glucose and fructosamine. They incorporate
our proprietary technology.

 Duet(R) Diabetes Control System--For the Health Care Professional

   We launched Duet in January 1998. It is designed for use by health care
professionals for in-office testing. Like In Charge, Duet has three components:
a GlucoProtein test strip, a glucose test strip and a hand-held monitor. The
monitor calculates the blood concentration of either fructosamine or glucose.
The GlucoProtein test strips utilize the same patented test strip technology as
the GlucoProtein test strips used for In Charge.

 ExpressView(TM) Monitor--Glucose-Only Testing

   We also market our proprietary glucose testing technology for selected
glucose-only market segments. We launched ExpressView in December 1999. It is
targeted to mail-order distributors servicing the Medicare market, as well as
to opportunities in the emerging store-brand segment where retailers package
products under their store name brand. We do not expend significant sales and
marketing resources on ExpressView. The ExpressView monitor and test strips use
the same core glucose testing technology as the In Charge product line.

Sales and Marketing

   Our sales and marketing strategy targets the following audiences:

  . health care professionals and pharmacists;

  . persons with diabetes; and

  . health care payors, including managed care providers.

   We market In Charge for use by consumers and Duet for use by health care
providers. We are in the process of building a national sales force to market
our products.

 In Charge Sales and Marketing Strategy

   National Retail Distribution. We have developed a broad based national
distribution strategy in order to make it easier for our customers to purchase
In Charge and its testing supplies. Currently, customers can purchase In Charge
through multiple channels including: national retail chains, independent retail
pharmacies, mail-order pharmacies, durable medical equipment suppliers, as well
as internet retailers such as Drugstore.com. They can also purchase our
products directly from us, either through our website or through an 800
telephone number. We primarily sell directly to national drug wholesalers,
which in turn supply retail pharmacies.

   Health Care Professionals. Our sales efforts for In Charge are aimed at
health care professionals such as diabetes educators, physicians treating large
populations of diabetes patients, and pharmacists who provide enhanced diabetes
services. An important part of our promotional selling message is the value of
GlucoProtein testing and its ability to improve medical outcomes. We promote
the quality of the clinical outcomes of our test rather than the features of
our monitors. We promote In Charge as the system of choice for patient self-
monitoring. We also believe that promoting Duet to physicians for in-office
testing will help both doctors and patients see the potential benefits of home
testing with In Charge. To complement our sales initiative, we expect to
advertise in journals and circulate direct mail advertisements. We will also
sponsor exhibits at local, regional and national meetings, and participate in
educational symposia to communicate the benefits of fructosamine testing.

   Direct Marketing to People with Diabetes. Patients with diabetes play a
major role in the decision to purchase brand specific systems, and ultimately
determine personal testing frequency and thus volume of test strip use. As a
result, direct-to-consumer communications and selling efforts play an important
role in increasing product sales as well as test strip use and are an integral
part of our marketing strategy. These selling efforts are aimed at diabetic
patient health fairs which afford an opportunity to educate, promote and sell
the In Charge system. On a targeted basis, we also give physicians free sample
monitors to give more patients and health care providers exposure to our
products. Additionally, we will create retail based direct-to-consumer
promotions to increase monitor sales and encourage test strip usage.

   We spend considerable resources to maintain our customer base. We also
encourage peer and patient referrals. We also focus on maintaining this
customer base and increasing revenue by promoting regular testing frequency. To
accomplish this, we intend to implement a series of frequent communications
with our customers to make them special offers for our products. Our customer
service representatives help to ensure that our In Charge customers are
satisfied with our product's performance and have all of their technical
questions addressed. Our customer service representatives are trained in direct
selling techniques intended to convert product inquiries into product sales.

   Health Care Payors and Managed Care. It is important that patients'
insurance cover our products and that health care payors agree to reimburse for
the use of our products. To achieve these objectives we have priced our
products similarly to other point-in-time glucose-only home tests and promoted
the potential clinical advantage of our GlucoProtein test over point-in-time
glucose-only testing. We believe that our combined

                                       37
<PAGE>

packaging of GlucoProtein test strips with glucose test strips has facilitated
health care payor acceptance. We will continue to pursue acceptance by health
care payors because we believe we can more easily convince physicians to
recommend In Charge to their patients if health care payors cover the product.

 Duet Sales and Marketing Strategy

   Health Care Professional Market. We have entered into an exclusive
distribution agreement with PSS World Medical. Under the agreement, which will
terminate in August 2002, PSS has committed to market, sell and distribute our
Duet products, with our support. We understand that PSS' sales representatives
are primarily focused on increasing and maintaining the revenue generated from
test strip sales to Duet users. As a secondary objective PSS' sales
representatives focus on increasing our base of Duet customers. Our own sales
representatives will focus on increasing our base of Duet customers among
physicians who manage large practices of diabetic patients and who currently
are staffed to perform in-office testing of various laboratory measurements. We
have positioned Duet as an in-office clinical decision tool for physicians. We
expect that if health care providers use Duet in their own practice, their
patients will be more likely to begin using In Charge for home monitoring.

   Health Care Payor and Managed Care. Medicare and select private insurers
currently reimburse health care professionals for GlucoProtein testing. We will
seek to maximize reimbursement for GlucoProtein testing over the long term
through the generation of supportive clinical data demonstrating an economic
benefit to the clinical value.

 Third Party Relationships

   We seek to enter into relationships with third parties to gain access to
their medical, marketing and sales capabilities and to incorporate GlucoProtein
testing as an integral part of the new advances and innovative drugs for the
treatment of diabetes. For example, Bristol-Myers Squibb recently agreed to
purchase In Charge for use in connection with two trials involving 800 patients
for their diabetes drug Glucovance.

Manufacturing

   We currently manufacture both our GlucoProtein test strip and our glucose
test strip at our facility in San Diego. Our monitors are produced and
assembled by outside suppliers. In Charge and ExpressView use the same monitor
housing and internal components. We perform final packaging of the monitors and
the test strips at our facility in San Diego.

   We obtain our In Charge and ExpressView monitors from a single supplier
based in Germany. While we have terminated our agreement with the former
manufacturer of our Duet monitor, we maintain an inventory of monitors that we
believe is sufficient to meet demand for at least the next two years. Our
monitors have been designed to use both standard off-the-shelf components and
customized components which meet our quality and performance specifications.
The customized components consist of the molded plastic parts, optics and
integrated circuits. Monitors are subject to inspection and testing processes,
which are performed at our San Diego facility to ensure suitability for use.
Some critical components for our test strips are also obtained from single
suppliers. These include molded plastic parts, various fabrics, papers, and
membranes, as well as specific active components. These suppliers are
significant sources of materials for our industry and many of the items are
commodity off-the-shelf products for these vendors.

   Production consists of the following manufacturing processes and steps: test
strip manufacture, monitor testing and customization, and final packaging. Each
process has integrated quality control steps. Test strip manufacture is an
automated process that includes formulation of the active components,
conversion to dry reagent format and assembly into functional units. Standard
equipment is used in the early phases of processing, with custom assembly
equipment used in the construction of the test strip. Testing of test strips
and monitors ensures that performance and quality standards are met in the
final product.

                                       38
<PAGE>

   We are required to manufacture in compliance with regulatory requirements in
addition to meeting our internal quality, quantity and cost targets. We have
implemented quality assurance systems which we believe comply with FDA Quality
System Regulations, or QSRs. Our facility is registered with the FDA and the
California Department of Health Services to manufacture medical devices. We
believe that we are in compliance with applicable QSRs. However, we have never
been through a QSR inspection, nor have our manufacturing lines at our outside
manufacturer been inspected for compliance with QSR regulations. If we or our
outside manufacturer fail to maintain our compliance, that failure could have a
material adverse effect on our business, results of operations and financial
condition.

   We utilize a company-wide enterprise resource planning system to control our
material and product inventories, as well as to manage other elements of the
supply chain. Our facility has been designed to optimize production flow and
manufacturing processes. Our overall plant capacity exceeds current demand.

Competition

   We are not aware of any other commercially available fructosamine self-tests
designed for home use. As a result, we consider our primary competitors in the
diabetes market to be manufacturers of point-in-time blood glucose monitoring
products for use in either the home, in the physician's office or in the
laboratory. The blood glucose monitoring market is characterized by intense
competition and is currently dominated by four major companies with established
products and distribution channels: LifeScan a subsidiary of Johnson & Johnson;
Roche Diagnostics; Abbott Laboratories; and Bayer Diagnostics, a division of
Bayer AG. Additional competitors in this market offer or are developing
products designed to give the patient the ability to monitor blood glucose
levels without the need for a fingerstick, either by drawing blood from a
different site on the body or by testing body fluids other than blood, such as
interstitial fluid or saliva. These competitors include TheraSense, Amira
Medical, Cygnus, Inverness Medical Technology, Integ and SpectRx.

   In addition, we compete with manufacturers of physicians' office and
laboratory-based glycated protein tests. Competitors in this market include
Roche Diagnostics, Sigma Chemical Company, Bio-Rad Laboratories and Bayer
Diagnostics. The most widely used glycated protein test is the HbA1c test,
which is available through laboratories and at physicians' offices. One
company, Metrika, recently announced that it received regulatory approval for
an in-home HbA1c test that requires a prescription, although this product has
not yet been commercially introduced.

   We also compete with companies that currently market or are developing
continuous blood glucose monitoring systems. These products seek to
continuously monitor a patient's blood glucose levels. The primary competitors
in this market include MiniMed, Animas Corporation, TheraSense and SpectRx.
This category of products is not intended to be available over the counter,
however, and some may require invasive surgical procedures to implant and
remove.

   Many of our competitors have significantly greater financial, research,
product development, marketing and sales, distribution and manufacturing
resources than us, as well as an installed base of customers and relationships
with diabetes educators, physicians and pharmacists. In addition, many of these
companies and their products have stronger brand recognition than us and their
products are more widely accepted than ours. We believe that the primary
competitive factors in our market include, among others:

  . price;

  . distribution capabilities;

  . customer service;

  . ease of use;

  . size of product; and

  . product quality and performance.

                                       39
<PAGE>

   Price competition for the placement of blood glucose monitors is intense and
involves marketing tactics such as rebates, trade-in offers and volume purchase
incentive programs. Our success will depend on our ability to:

  . educate health care professionals and diabetes patients about the value
    of our GlucoProtein tests;

  . establish national retail distribution relationships;

  . market our products;

  . obtain reimbursement for our products;

  . maintain our proprietary position with regard to our core technologies;
    and

  . develop new products and innovative technologies.

Patents and Proprietary Rights

   Our success will depend in part on our ability to maintain patent protection
for our products, to preserve our trade secrets and to operate without
infringing the proprietary rights of third parties. We have sought patent
protection for each of the areas of invention embodied in our products. We have
been issued eight patents by the U.S. Patent and Trademark Office relating to
various aspects of the technology underlying InCharge, the Duet, and
ExpressView monitors and testing strips. These technologies include:

  . our multilayer test strip technology for both GlucoProtein and glucose;

  . the two-test basis of the In Charge and Duet monitors;

  . certain electrochemical measurement processes for the determination of
    fructosamine;

  . certain blood separation technologies particularly suited to multilayer
    strips;

  . improved methods for timing reaction measurements which improve
    performance and shorten test time; and

  . sonically treated test strips which decrease the volume of blood sample
    needed.

   Our patent for the two-test basis of the In Charge and Duet monitor is
fundamental to our current business, and covers a system for measuring the
glycemic condition of a patient by measuring glucose and fructosamine on the
same monitor.

   The integrated assay system application is directly applicable to broadly
monitoring the treatment of people with diabetes, especially those with Type 2
diabetes who may be taking oral drugs. We have filed corresponding
international patent applications seeking similar patent protection outside the
U.S.

   We have licensed and may continue to license other technologies that may be
relevant to the In Charge, Duet and ExpressView products. In particular, we
have licensed technologies relating to our GlucoProtein test strips under a
non-exclusive license. This license will remain in effect under certain
conditions, primarily payment of an ongoing royalty for the life of the patent
and for the life of each related foreign country patent application.

   We also rely upon trade secrets and proprietary know-how in our
manufacturing processes. We require each of our employees, consultants,
advisors and vendors to execute a confidentiality agreement upon the
commencement of their relationship with us.

   We cannot be certain that the patents we own and license will prove to be
enforceable, that additional patents will be issued, that we will be able to
maintain our rights under the license, or that we will be able to procure
additional licenses as necessary in the future on reasonable terms, if at all.
In addition, we cannot assure you that the technologies we utilize do not
infringe upon the proprietary rights of others. Nor can we

                                       40
<PAGE>

assure you that we will be able to maintain and enforce our existing patent
protections. Moreover, others could independently develop similar or superior
technologies, and our trade secrets and know-how could become known to others.
Any litigation relating to our intellectual property rights could result in
substantial costs to and a diversion of effort by us, but may be necessary to
enforce any patents issued to us, protect trade secrets or know-how owned by
us, defend us against claimed infringement of the rights of others or determine
the scope and validity of the proprietary rights of others.

Third Party Reimbursement

   Private insurance companies, self-insured employers, health maintenance
organizations, pharmacy benefit managers and governmental payors under Medicare
and Medicaid programs are a source of reimbursement to users of blood glucose
monitoring systems and related products. Sales of our products in some markets
will be dependent in part on availability of adequate physician reimbursement
and insurance coverage for patients from these health care payors.

   Sales of In Charge are also significantly dependent upon third party
acceptance and coverage. To facilitate acceptance and coverage, we have
combined both glucose test strips and GlucoProtein test strips into one
package. Currently, Medicare covers our In Charge monitor as well as our In
Charge combination test strip package since their respective retail prices are
within Medicare's coverage limit for glucose test strips and glucose monitors.
Medicare at present does not cover GlucoProtein test strips if purchased
separate from our combination package. Our longer-term goal is to have
GlucoProtein test strips recognized and covered separately for consumers
eligible for Medicare benefits. The Office of the Inspector General of the U.S.
Department of Health and Human Services 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
monitors and test strips.

   Private insurance, pharmacy benefit management companies administering
benefits on behalf of managed care organizations, and managed care
organizations themselves, have begun to recognize In Charge as clinically
unique from glucose testing and as a result have accepted our monitor and test
strips. Both our combination GlucoProtein and glucose test strip package and
our separate GlucoProtein-only package have been granted reimbursement coverage
by national and regional managed care and health care payors. We expect this
acceptance in the private sector of GlucoProtein test strips separate from our
combination package to facilitate acceptance within Medicare. Our strategy is
to begin the process of application to additional health care payors within
specific regional areas to ensure reimbursement ahead of our sales force
expansion, lessening potential barriers to our products' acceptance.

   Health care professionals performing in-office testing with Duet are
reimbursed at specified rates under Medicare. Private insurance companies as
well as most state Medicare programs have routinely adopted this Federal
reimbursement level. Our long-term strategy is to maximize the reimbursement
level for in-office GlucoProtein testing among these audiences.

Government Regulation

   Our products are medical devices subject to extensive regulation by the FDA
and other regulatory bodies. FDA regulations govern, among other things, the
following activities that we will perform:

  . product design and development;

  . product testing;

  . product labeling;

  . product storage;

  . premarket clearance or approval;

                                       41
<PAGE>

  . advertising and promotion; and

  . product sales and distribution.

 FDA's premarket clearance and approval requirements

   Unless an exemption applies, each medical device we wish to commercially
distribute in the U.S. will require either prior 510(k) clearance or prior PMA
approval from the FDA under the Federal, Food, Drug, and Cosmetic Act. Devices
deemed to pose relatively minimal risk are placed in either class I or II,
which requires the manufacturer to submit a premarket notification requesting
permission for commercial distribution; this is known as 510(k) clearance. Some
low risk devices are exempted from this requirement. Devices deemed by FDA to
pose the greatest risk, such as life-sustaining, life-supporting or implantable
devices, or devices deemed not substantially equivalent to a previously cleared
510(k) device or a preamendment class III device for which PMA applications
have not been called for by the FDA, are placed in class III, requiring PMA
approval.

   510(k) Clearance Pathway. To obtain 510(k) clearance, we must submit a
premarket notification demonstrating that the proposed device is substantially
equivalent in intended use and in safety and effectiveness to a previously
cleared 510(k) device or a device that was in commercial distribution before
May 28, 1976 for which the FDA has not yet called for the submission of PMA
applications. The FDA's 510(k) clearance pathway usually takes from four to
twelve months, but it can take significantly longer.

   Blood glucose testing systems have generally qualified for clearance under
510(k) procedures. In 1999, we received 510(k) clearances for In Charge and
ExpressView.

   After a device receives 510(k) clearance, any modification that could
significantly affect its safety or effectiveness, or that would constitute a
major change in its intended use, generally requires a new 510(k) clearance or
could require a PMA approval. The FDA requires each manufacturer to make this
determination in the first instance, but the FDA can review any such decision.
If FDA disagrees with a manufacturer's decision not to seek a new 510(k)
clearance, the Agency may retroactively require a manufacturer to seek 510(k)
clearance or PMA approval. The FDA also can require the manufacturer to cease
marketing and/or recall the modified device until 510(k) clearance or PMA
approval is obtained. We have made and plan to continue to make additional
product enhancements to In Charge, Duet and ExpressView that we believe do not
require new 510(k) clearances. We cannot assure you, however, that the FDA will
agree with any of our determinations. If the FDA requires us to obtain new
510(k) clearances for any of our enhancements, we may be prohibited from
marketing the modified device until the 510(k) notification is cleared by the
FDA. In addition, we cannot assure you that the FDA will grant such clearance.
If the FDA determines the changes are not eligible for 510(k) clearance, we
will need to seek PMA approval. We cannot assure you that we will submit a PMA
application for any such changes or that once submitted, the PMA application
will be accepted for filing, found approvable, or if found approvable, will not
include unfavorable labeling restrictions.

   PMA Approval Pathway. If the FDA denies 510(k) clearance for one of our
products, we must follow the PMA approval pathway for that product before
marketing commences. A PMA application requires proof of the safety and
effectiveness of the device to the FDA's satisfaction. A PMA application
generally contains extensive preclinical and clinical trial data and also
information about the device and its components including, among other things,
device design, manufacturing and labeling. After approval of a PMA, a new PMA
or PMA supplement is required in the event of a significant modification to the
device, its labeling or its manufacturing process. The PMA pathway is much more
costly, lengthy and uncertain than 510(k) clearance. It generally takes from
one to three years, or even longer.

 Pervasive and continuing FDA regulation

   After a device is placed on the market, numerous regulatory requirements
apply. These include: the quality system regulations, or QSR, which requires
manufacturers to follow elaborate design, testing, control,

                                       42
<PAGE>

documentation and other quality assurance procedures during the manufacturing
process; labeling regulations; the FDA's general prohibition against promoting
products for unapproved or "off-label" uses; and the Medical Device reporting
regulations, which require that manufacturers report to the FDA if their device
may have caused or contributed to a death or serious injury or malfunctioned in
a way that would likely cause or contribute to a death or serious injury if it
were to recur. In June, 1999, we received a notice of violation letter from the
FDA regarding information on our website and a promotional brochure for the
Duet Glucose Control Monitoring System, which the FDA found to be misleading.
Among other things, we removed the information from our website and labeling.
In August, 1999, we received a response from the FDA that our corrections were
acceptable.

   We are subject to inspection by the FDA and the Food and Drug Branch of the
California Department of Health Services, or CDHS. The FDA has not inspected
our manufacturing facilities, and we cannot assure you that we will
successfully pass such an inspection or maintain compliance in the future.
Failure to comply with applicable regulatory requirements can result in
enforcement action by the FDA, which may include the following sanctions:

  . fines, injunctions, and civil penalties;

  . recall or seizure of our products;

Board Composition

   Upon the closing of this offering, in accordance with the terms of our
certificate of incorporation, the terms of office of the board of directors
will be divided into three classes:

  . Class I directors, whose term will expire at the annual meeting of
    stockholders to be held in 2001;

                                       46
<PAGE>

  . Class II directors, whose term will expire at the annual meeting of
    stockholders to be held in 2002; and

  . Class III directors, whose term will expire at the annual meeting of
    stockholders to be held in 2003.

   Our Class I directors will be Nancy Katz and Clint Severson, our Class II
directors will be John Burd, Michael Beeuwsaert and Gary Stroy and our Class
III directors will be Ansbert Gadicke and Charles Hsu. At each annual meeting
of stockholders, after the initial classification, the successors to directors
whose terms will then expire will be elected to serve from the time of election
and qualification until the third annual meeting following election. Any
additional directorships resulting from an increase in the number of directors
will be distributed among the three classes so that, as nearly as possible,
each class will consist of one-third of the directors. This classification of
the board of directors may have the effect of delaying or preventing changes in
control or management of our company.

Committees of the Board of Directors

   The audit committee of the board of directors reviews our internal
accounting procedures and consults with and reviews the services provided by
our independent accountants.

   Our compensation committee reviews and makes recommendations to the board
concerning compensation and benefits of all of our executive officers,
administers our stock option plan and establishes and reviews general policies
relating to compensation and benefits of our employees.

Director Compensation

   Our directors do not currently receive any cash compensation for services on
the board of directors or any committee thereof, but directors may be
reimbursed for certain expenses in connection with attendance at board and
committee meetings. In addition, all directors are eligible to participate in
our 2000 Equity Incentive Plan.

   The 2000 Equity Incentive Plan also provides for automatic stock option
grants to non-employee directors serving on the board. Each person who is
elected or appointed for the first time to be a non-employee director
subsequent to the adoption of the Equity Incentive Plan will be granted an
initial grant on the date of his or her election or appointment to the board to
purchase 10,000 shares of our common stock.

   The 2000 Equity Incentive Plan also provides that eligible non-employee
directors will, on the day following each annual meeting, automatically receive
an annual grant to purchase 5,000 shares of our common stock commencing, as
applicable, with the annual meeting in 2001; provided, however, that if the
person has not been serving as a non-employee director for the entire period
since the preceding annual meeting, then the number of shares subject to the
annual grant shall be reduced pro rata for each full quarter prior to the date
of grant during which such person did not serve as a non-employee director.

   The non-employee director stock options will have a maximum term of ten
years and generally must be exercised prior to the earliest of 18 months
following the death of the non-employee director, 12 months from the
termination of service on the board by the non-employee director due to a
disability, 3 months from the termination of the service of the non-employee
director for any other reason, or the expiration of the original term of the
stock option. One-thirty sixth of shares pursuant to each initial grant of a
non-employee director option vest each month following the date of grant. One
twelfth of the shares pursuant to each annual grant of a non-employee director
option vest each month following the date of grant. All options granted to non-
employee directors will be granted at the fair market value of the common stock
on the date of grant.

Compensation Committee Interlocks and Insider Participation

   None of our executive officers serves as a member of the board of directors
or compensation committee of any entity that has one or more executive officers
serving on our board of directors or compensation committee.

Employee Benefit Plans

   2000 Equity Incentive Plan. In September 1996, we adopted our 1996 Stock
Option Plan. In October 2000, we approved an amendment and restatement of the
plan, and re-named the plan the 2000 Equity Incentive Plan. As amended, a total
of 2,400,000 shares of common stock are authorized for issuance under the plan.
The plan includes an "evergreen" provision providing that an additional number
of shares will automatically be added annually to the shares authorized for
issuance under the plan. The amount added each year will be the number of
shares equal to 3% of our outstanding capital stock, or 900,000, or an amount
expressly determined for such year by our board of directors, whichever is
lowest. Shares subject to stock awards that have expired or otherwise
terminated without having been exercised in full again become available for
grant.

   The plan permits the grant of options to our directors, officers, other
employees and consultants. Options may be either incentive stock options to
employees within the meaning of Section 422 of the Internal Revenue Code or
non-statutory stock options. In addition, the plan permits the grant of stock
bonuses and rights to purchase restricted stock. Except in specified
circumstances, no person may be granted options covering more than 2,000,000
shares of common stock in any calendar year. See also the discussion under
"Non-Employee Director Stock Option Grants" regarding automatic grants to non-
employee directors in the plan.

   The plan is administered by the board of directors or a committee appointed
by the board. The board has delegated the authority to administer the plan to
our compensation committee. Subject to the limitations set forth in the plan,
the administrator has the authority to select the eligible persons to whom
award grants are to be made, to designate the number of shares to be covered by
each award, to determine whether an option is to be an incentive stock option
or a non-statutory stock option, to establish vesting schedules, to specify the
exercise price of options and the type of consideration to be paid upon
exercise and, subject to specified restrictions, to specify other terms of
awards.

   The maximum term of options granted under the plan is ten years. Incentive
stock options granted under the plan are generally non-transferable. Non-
statutory stock options are generally non-transferable, although the applicable
option agreement may permit some transfers. Options generally expire three
months after the termination of an optionholder's service. However, if an
optionholder is permanently disabled, or dies, during his or her service, that
person's options generally may be exercised up to 12 and 18 months,
respectively, following disability or death.

   The exercise price of options granted under the plan is determined by the
board of directors or committee in accordance with the guidelines set forth in
the plan. The exercise price of an incentive stock option cannot be less than
100% of the fair market value of the common stock on the date of grant. The
exercise price of a non-statutory stock option cannot be less than 85% of the
fair market value of the common stock on the date of grant.

                                       49
<PAGE>

   Options granted under the plan vest at the rate determined by the board of
directors or committee and specified in the option agreement. The terms of any
stock bonuses or restricted stock purchase awards granted under the plan will
be determined by the board of directors or committee. The purchase price of
restricted stock under any restricted stock purchase agreement will be
determined by the board of directors or committee and will not be less than 85%
of the fair market value of our common stock on the date of grant. Stock
bonuses and restricted stock purchase agreements awarded under the plan are
generally non-transferable, although the applicable award agreement may permit
some transfers.

   In the event of a change in control in our ownership as defined in our plan,
all outstanding stock awards under the plan must either be assumed or
substituted by the surviving entity. In the event the surviving entity does not
assume or substitute for the stock awards, then the vesting and exercisability
of outstanding awards will accelerate prior to the change in control and the
awards will terminate to the extent not exercised prior to the change in
control. Pursuant to the terms of individual option agreements, upon a change
of control all of the unvested options held by Mr. Beeuwsaert, our President
and Chief Executive Officer, will automatically fully vest; and one half of the
then-unvested portion of each option held by each of our officers at the
director level and above will automatically vest. Additionally, if within one
month prior to or 13 months following a change of control any employee who
holds options, including directors and above, are terminated, has his job title
or responsibilities materially altered or is asked to move more than 50 miles
as a condition of maintaining employment, that employee's unvested options will
automatically fully vest. The board of directors may amend or terminate the
plan at any time. Amendments will generally be submitted for stockholder
approval to the extent required by applicable law.

   As of October 11, 2000, we had issued and outstanding under the plan options
to purchase 1,595,066 shares of common stock and 73,920 shares had been
purchased upon the exercise of previously held options. The per share exercise
prices of these outstanding options range from $0.20 to $7.00.

   2000 Employee Stock Purchase Plan. In October 2000, we adopted the 2000
Employee Stock Purchase Plan. A total of 500,000 shares of common stock has
been reserved for issuance under the purchase plan. The plan includes an
"evergreen" provision providing that an additional number of shares will
automatically be added annually to the shares authorized for issuance under the
plan. The amount added each year will be the number of shares equal to 1% of
our outstanding capital stock, or 300,000, or an amount expressly determined
for such year by our board of directors, whichever is lowest. The purchase plan
is intended to qualify as an employee stock purchase plan within the meaning of
Section 423 of the Internal Revenue Code. Under the purchase plan, the board of
directors may authorize participation by eligible employees, including
executive officers, in periodic offerings following the commencement of the
purchase plan. The initial offering under the purchase plan will commence on
the effective date of this offering and terminate on May 15, 2001.

   Unless otherwise determined by the board of directors, employees are
eligible to participate in the purchase plan only if they are employed by us or
one of our subsidiaries designated by the board of directors for at least 20
hours per week and are customarily employed for at least five months per
calendar year. Employees who participate in an offering may have up to 15% of
their earnings withheld pursuant to the purchase plan. The amount withheld is
then used to purchase shares of common stock on specified dates determined by
the board of directors. The price of common stock purchased under the purchase
plan will be equal to 85% of the lower of the fair market value of the common
stock at the commencement date of each offering period or the relevant purchase
date. Employees may end their participation in the offering at any time during
the offering period, and participation ends automatically upon termination of
employment.

   In the event of a merger, reorganization, consolidation or liquidation, or
other change in control, the board of directors has discretion to provide that
each right to purchase common stock will be assumed or an equivalent rights
substituted by the successor corporation or the board of directors may provide
for all sums collected by payroll deductions to be applied to purchase stock
immediately prior to such merger or other transaction. The board of directors
has the authority to amend or terminate the purchase plan, provided however,
that no such action may adversely affect any outstanding rights to purchase
common stock.

   401(k) Plan. We sponsor the LXN Corporation 401(k) Plan. Employees who
complete three months of service with us are eligible to participate. These
participants may contribute from 1% up to 15% of their current compensation, up
to a statutorily prescribed annual limit. Participant contributions are held in
trust as required by law. Individual participants may direct the trustee to
invest their accounts in authorized investment alternatives. We may make
discretionary matching contributions to the 401(k) Plan each year in an amount
equal to a percentage of the participant's salary reduction contributions.
Salary reduction contributions in excess of 6% of the participant's
compensation are disregarded for purposes of the match. In addition, we may
make discretionary and special contributions each year, although we have not
done so to date. Each participant is fully vested in his or her salary
reduction contributions and our special contributions to the 401(k) Plan. The
401(k) Plan is intended to qualify under Section 401(a) of the Internal Revenue
Code so that contributions to the 401(k) Plan, and income earned on such
contributions, are not taxable to participants until withdrawn or distributed
from the 401(k) Plan.

Severance Agreement

   We have entered into an Executive Severance Benefits Agreement with Mr.
Beeuwsaert under which we would be obligated to make a one-time payment to him
equal to 12 months of his base salary and to continue to pay his health
insurance premiums for up to an additional 12 months if we terminate him
without cause or "constructively terminate" him. A "constructive termination"
is defined in the agreement as a substantial reduction in his job title,
responsibilities or reporting level, a relocation of our executive offices more
than 30 miles from San Diego, California, a reduction in his base salary or
benefits or a failure by us to obtain from any successor company a commitment
to assume this agreement.

                          DESCRIPTION OF CAPITAL STOCK

   Following the closing of this offering, our authorized capital stock will
consist of 35,000,000 shares of common stock, $0.01 par value per share, and
5,000,000 shares of preferred stock, $0.01 par value per share. As of October
16, 2000, there were 1,109,672 shares of common stock outstanding, held by
approximately 59 stockholders, and warrants to purchase 19,547 shares of common
stock outstanding. Upon the closing of this offering, an additional 8,018,686
shares of common stock, held by approximately      stockholders, will be issued
upon conversion of all outstanding shares of preferred stock, based on the
outstanding shares of preferred stock as of October 16, 2000. In addition, as
of October 16, 2000, there were outstanding warrants to purchase 881,554 shares
of preferred stock, of which warrants to purchase 845,832 shares terminate upon
the closing of this offering if not earlier exercised; and if these warrants
are exercised prior to termination, the issued preferred stock would convert
into an additional 8,900,240 shares of common stock upon the closing of this
offering.

Common Stock

   Subject to preferences that may apply to shares of preferred stock
outstanding at the time, the holders of outstanding shares of common stock are
entitled to receive dividends out of assets legally available at such times and
in such amounts as the board may from time to time determine. Each stockholder
is entitled to one vote for each share of common stock held on all matters
submitted to a vote of stockholders. Cumulative voting for the election of
directors is not provided for in our certificate of incorporation, which means
that the holders of a majority of the shares voted can elect all of the
directors then standing for election. The common stock is not entitled to
preemptive rights and is not subject to conversion or redemption. Each
outstanding share of common stock is, and all shares of common stock to be
outstanding upon completion of this offering will be, duly authorized, fully
paid and nonassessable.

Preferred Stock

   Following the conversion of our preferred stock into common stock prior to
this offering, our board of directors will have the authority, without further
action by the stockholders, to issue up to 5,000,000 shares of preferred stock
in one or more series and to fix the designations, powers, preferences,
privileges, and relative participating, optional or special rights and the
qualifications, limitations or restrictions thereof, including dividend rights,
conversion rights, voting rights, terms of redemption and liquidation
preferences, any or all of which may be greater than the rights of the common
stock. The board of directors, without stockholder approval, can issue
preferred stock with voting, conversion or other rights that could adversely
affect the voting power and other rights of the holders of common stock.
Preferred stock could thus be issued quickly with terms calculated to delay or
prevent a change in control or make removal of management more difficult.
Additionally, the issuance of preferred stock may have the effect of decreasing
the market price of the common stock, and may adversely affect the voting and
other rights of the holders of common stock. At present, we have no plans to
issue any of the preferred stock after this offering.

Anti-Takeover Provisions

 Delaware Law

   We are governed by the provisions of Section 203 of the Delaware General
Corporation Law. In general, Section 203 prohibits a public Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner. A "business combination"
includes mergers, asset sales or other transactions resulting in a financial
benefit to the stockholder. An "interested stockholder" is a person who,
together with affiliates and associates, owns, or within three years, did own,
15% or more of the corporation's outstanding voting stock. This provision could
delay, discourage or prohibit transactions not approved in advance by the board
of directors, such as takeover attempts that might result in a premium over the
market price of the common stock.


                                       55
<PAGE>

 Charter and Bylaw Provisions

   Our certificate of incorporation and bylaws contain certain provisions that
could discourage potential takeover attempts and make attempts by stockholders
to change management more difficult. Our certificate of incorporation provides
that stockholders may not take action by written consent but may only act at a
stockholders' meeting, and that special meetings of our stockholders may only
be called by the chairman of the board or a majority of the board.

Registration Rights

   The holders of 8,018,686 shares of common stock and 881,554 shares of common
stock issuable upon exercise of outstanding warrants have certain rights with
respect to the registration of those shares under the Securities Act of 1933.
Beginning 12 months after the date of this offering, if requested by holders of
these registrable securities, we must file up to two registration statements to
register our securities so long as the aggregate offering price of each
offering, net of any underwriting discounts and commissions, is at least $7.5
million. In addition, if we propose to register any of our shares of common
stock under the Securities Act other than in connection with a company employee
benefit plan or certain corporate acquisitions, mergers or reorganizations, the
holders of these registrable securities may require us to include all or a
portion of their shares in such registration, subject to certain rights of the
managing underwriter to limit the number of shares in any such offering.
Further, beginning six months after the date of this offering, the holders of
these registrable securities may require us to register all or any portion of
their registrable securities on Form S-3 when such form becomes available to
us, as long as the aggregate offering price would exceed $500,000, subject to
certain other conditions and limitations. We may be required to effect up to
one Form S-3 registration in any six month period. We will bear all expenses
incurred in connection with these registrations (other than underwriters'
discounts and commissions). These registration rights expire five years after
the closing of this offering. In addition, no holder of registrable securities
will be entitled to registration rights if and so long as such holder can sell
all of its registrable securities in compliance with Rule 144 of the Securities
Act during any three month period.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no market for our common stock, and
we cannot assure you that a significant public market for the common stock will
develop or be sustained after this offering. Future sales of substantial
amounts of our common stock (including shares issued upon exercise of
outstanding options and warrants) in the public market after this offering
could adversely affect market prices prevailing from time to time and could
impair our ability to raise capital through sale of our equity securities. As
described below, no shares currently outstanding will be available for sale
immediately after this offering due to certain contractual restrictions on
resale. Sales of substantial amounts of our common stock in the public market
after the restrictions lapse could adversely affect the prevailing market price
and our ability to raise equity capital in the future.

   Upon completion of this offering, we will have outstanding           shares
of common stock, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options that do not expire upon the
closing. Of these shares, the           shares sold in this offering will be
freely tradable without restriction under the Securities Act unless purchased
by our "affiliates" as that term is defined in Rule 144 under the Securities
Act. The remaining 10,009,912 shares held by existing stockholders are subject
to various lock-up agreements providing that, with certain limited exceptions,
the stockholder will not offer, sell, contract to sell, grant an option to
purchase, make a short sale or otherwise dispose of or engage in any hedging or
other transaction that is designed or reasonably expected to lead to a
disposition of any shares of common stock or any option to purchase shares of
common stock or any securities exchangeable for or convertible into shares of
common stock for a period of 180 days after the date of this prospectus without
the prior written consent of Robertson Stephens. As a result of these lock-up
agreements, notwithstanding possible earlier eligibility for sale under the
provisions of Rules 144, 144(k) and 701, none of these shares will be salable
until 181 days after the date of this prospectus. Beginning 181 days after the
date of this prospectus, 9,256,592 of these shares will be eligible for sale in
the public market. Thereafter, 717,598 of these shares will become eligible for
sale starting in October 2001. In addition, as of October 16, 2000, there were
outstanding options to purchase 1,595,066 shares common stock. All of such
options will be subject to lock-up agreements. Robertson Stephens may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to lock-up agreements.

   In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned unregistered shares for at least one year (including
the holding period of any prior owner except an affiliate) would be entitled to
sell within any three-month period a number of shares that does not exceed the
greater of: 1% of the number of shares of common stock then outstanding (which
will equal approximately         shares immediately after this offering); or
the average weekly trading volume of the common stock during the four calendar
weeks preceding the filing of a Form 144 with respect to such sale. Sales under
Rule 144 are also subject to certain manner of sale provisions and notice
requirements and to the availability of current public information about us.
Under Rule 144(k), a person who is not deemed to have been an affiliate of us
at any time during the three months preceding a sale, and who has beneficially
owned the shares proposed to be sold for at least two years (including the
holding period of any prior owner except an affiliate), is entitled to sell
such shares without complying with the manner of sale, public information,
volume limitation or notice provisions of Rule 144.

   Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with certain restrictions, including the holding period requirement,
of Rule 144. Any of our employees, officers, directors or consultants who
purchased his or her shares pursuant to a written compensatory plan or contract
may be entitled to rely on the resale provisions of Rule 701. Rule 701 permits
affiliates to sell their Rule 701 shares under Rule 144 without complying with
the holding period requirements of Rule 144. Rule 701 further provides that
non-affiliates may sell such shares in reliance on Rule 144 without having to
comply with the holding period, public information, volume limitation or notice
provisions of Rule 144. All holders of Rule 701

                                       57
<PAGE>

shares are required to wait until 90 days after the date of this prospectus
before selling such shares. However, all shares issued pursuant to Rule 701 are
subject to lock-up agreements and will only become eligible for sale at the
earlier of the expiration of the 180-day lock-up agreements or no sooner than
90 days after the offering upon obtaining the prior written consent of
Robertson Stephens.

   The underwriters' representatives have advised us that the underwriters
propose to offer the shares of common stock 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 of not more than $   per share, of
which $   may be reallowed to other dealers. After the completion of this
offering, the initial public offering price, concession and reallowance to
dealers may be reduced by the underwriters' representatives. No such reduction
shall change the amount of proceeds to be received by us as set forth on the
cover page of this prospectus. The common stock is offered by the underwriters
as stated herein, subject to receipt and acceptance by them and subject to
their right to reject any order in whole or in part.

 Over-Allotment Option

   We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to
additional shares of common stock at the same price per share as we will
receive for the            shares that the underwriters have agreed to
purchase. To the extent that the underwriters exercise such option, each of the
underwriters will have a firm commitment, subject to certain conditions, to
purchase approximately the same percentage of such additional shares that the
number of shares of common stock to be purchased by it shown in the above table
represents as a percentage of the            shares offered hereby. If
purchased, such additional shares will be sold by the underwriters on the same
terms as those on which the        shares are being sold. We will be obligated,
under the option, to sell shares to the extent the option is exercised. The
underwriters may exercise this option only to cover over-allotments made in
connection with the sale of the shares of common stock offered hereby. If this
option is exercised in full, the total public offering price, underwriting
discounts and commissions and proceeds to us will be $          , $         and
$            , respectively.

 Indemnity

   We have agreed to indemnify the underwriters against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representations and warranties contained in the
underwriting agreement, or to contribute to payments that the underwriters may
be required to make in respect thereof.

 Lock-up Agreements

   Our directors, executive officers, employees and 1% stockholders have agreed
to the underwriters' representatives that, for a period of 180 days after the
date to this prospectus, they will not offer to sell, contract to sell or
otherwise sell, dispose of, loan, pledge or grant any option to purchase any
shares of common stock or any securities convertible into, or exchangeable for,
or any rights to purchase or acquire, shares of common stock, now owned or
hereafter acquired directly by such holders or with respect to which they have
the power to disposition, without the prior written consent of Robertson
Stephens, Inc., which may, in its sole discretion and at any time or from time
to time, without notice, release all or any portion of the shares subject to
the lock-up agreements.

 Future Sales

   We have agreed that, for a period of 180 days after the date of this
prospectus, we will not without prior written consent of Robertson Stephens,
Inc., issue, sell contract to sell or otherwise dispose of any shares of common
stock, any options or warrants to purchase any shares of common stock or any
securities convertible into, exercisable for or exchangeable for shares of
common stock other than our sale of shares in this offering, the issuance of
common stock upon the exercise of outstanding options and our grant of options
to purchase shares of common stock under existing stock option or stock
purchase plans.

 Online Prospectus

   One of the underwriters, Prudential Securities Incorporated, also markets
securities online through its PrudentialSecurities.com division. Clients of
Prudential AdvisorSM, a full service brokerage firm program, may view offering
terms and a prospectus online and place orders through their financial
advisors. Other than the prospectus in electronic format, the information on
this Web site is not intended to be part of this prospectus or the registration
statement of which this prospectus forms a part and has not been approved
and/or endorsed by us or any underwriter in such capacity and should not be
relied on by prospective investors.

 Directed Share Program

   The underwriters have reserved up to 5% of the common stock to be issued by
us and offered for sale in this offering, at the initial public offering price,
to directors, officers, employees, business associates and persons otherwise
connected to us. The number of shares of common stock available for sale to the
general public will be reduced to the extent these individuals purchase
reserved shares. Any reserved shares not purchased will be offered by the
underwriters to the general public on the same basis as the other shares
offered by this prospectus.

   The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed 5% of the total number of shares offered.

 Listing

   We have applied to list our common stock on the Nasdaq National Market
under the symbol "LXNC."

 No Prior Public Market

   Prior to this offering, there has been no public market for our common
stock. The initial public offering price for the common stock will be
determined by negotiation between us and the representatives. Among the
factors to be considered in determining the initial public offering price are
the prevailing market and economic conditions, our revenues and earnings,
market valuations of other companies engaged in activities similar to ours,
estimates of our business potential and prospects, the present state of our
business operations, our management and other factors deemed relevant. The
estimated initial public offering price range set forth on the cover page of
this prospectus is subject to change as a result of market conditions and
other factors. A pricing committee of our board of directors will establish
the initial public offering price following such negotiations.

 Stabilization

   The underwriters' representatives have advised us that, pursuant to
Regulation M under the Securities Exchange Act of 1934 certain persons
participating in the offering may engage in transactions, including
stabilizing bids, syndicate covering transactions or the imposition of penalty
bids, which may have the effect of stabilizing or maintaining the market price
of the common stock at a level above that which might otherwise prevail in the
open market. A "stabilizing bid" is a bid for or the purchase of the common
stock on behalf of the underwriters for the purpose of fixing or maintaining
the price of the common stock. A "syndicate covering transaction" is a bid for
or the purchase of the common stock on behalf of the underwriters to reduce a
short position incurred by the underwriters in connection with this offering.
A "penalty bid" is an arrangement permitting the underwriters' representatives
to reclaim the selling concession otherwise accruing to an underwriter or
syndicate member in connection with the offering if the common stock
originally sold by such underwriter or syndicate member is purchased by
underwriters' representatives in a syndicate covering transaction and has
therefore not been effectively placed by such underwriter or syndicate member.
The underwriters' representatives have advised us that such transactions may
be effected on the Nasdaq National Market or otherwise and, if commenced, may
be discontinued at any time.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of LXN Corporation

   The stock split described in Note 1 to the financial statements had not been
consummated at March 17, 2000. When it has been consummated, we will be in a
position to furnish the following report:

   "In our opinion, the accompanying balance sheets and the related statements
of operations, of redeemable convertible preferred stock and stockholders'
deficit, and of cash flows present fairly, in all material respects, the
financial position of LXN Corporation at December 31, 1999 and 1998, and the
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1999 in conformity with accounting principles
generally accepted in the United States of America. 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 of these statements in accordance with auditing standards
generally accepted in the United States of America, which 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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above."

                         NOTES TO FINANCIAL STATEMENTS

1. The Company

 The Business

   LXN Corporation (the "Company") was incorporated in Delaware on July 7,
1993. The Company develops, manufactures and markets products for people with
diabetes, which allow patients and health care professionals to better monitor
the effectiveness of treatment regimens and make therapy changes to improve
overall glucose control. The Company derives all its revenues from the sale of
three products. Duet, which is currently marketed to health care professionals
through an exclusive distributor serving the U.S. physician office market, was
introduced in January 1998. In Charge, which is sold primarily to wholesalers
that serve national and regional retail pharmacy chains as well as local
pharmacies, was introduced in October 1999. ExpressView, which is sold
primarily to mail-order firms serving Medicare patients, was introduced in
December 1999.

   The Company's business consists of a single operating segment. Substantially
all revenues are generated from customers located within the U.S., and all
long-lived assets are located in the U.S.

 Stock Split

   In connection with its proposed initial public offering ("IPO"), the Company
will be effecting a two-for-one stock split. All per share and share amounts in
the financial statements have been retroactively restated to reflect the stock
split.

 Capital Resources

   The Company has been successful in completing several rounds of private
equity financing with its last round totaling approximately $5 million during
October 2000. However, the Company has incurred substantial losses and negative
cash flows from operations in every fiscal period since inception. The Company
incurred losses from operations of $5,535,000, $11,997,000, and $10,178,000 for
the years ended December 31, 1997, 1998, and 1999, respectively. The Company
incurred negative cash flows from operations of $4,673,000, $10,107,000, and
$8,225,000 for the years ended December 31, 1997, 1998, and 1999, respectively.
As of December 31, 1998 and 1999, the Company had accumulated deficits of
$21,488,000 and $31,674,000, respectively. Management expects operating losses
and negative cash flows from operations to continue for at least the next two
years and anticipates that losses will increase significantly from current
levels because of additional costs and expenses related to brand development,
marketing and other promotional activities, expansion of product offerings and
development of relationships with other businesses. In addition, the Company's
bank credit facilities are due on demand as a result of the current violation
of certain performance covenants. Failure to generate sufficient revenues,
raise additional capital or reduce certain discretionary spending could have a
material adverse effect on the Company's ability to achieve its intended
business objectives. Based on the Company's current business projections and
its current cash available, assuming that the proposed IPO is not completed and
there are no unusual trends in cash expenditures, and assuming that the bank
demands full repayment of its credit facilities, the Company is projected to
exhaust its cash resources in early 2001.

2. Summary of Significant Accounting Policies

 Unaudited Financial Statements

   The interim financial statements as of June 30, 2000 and for the six months
ended June 30, 1999 and 2000 are unaudited and have been prepared on the same
basis as the audited financial statements. In the opinion of management, these
unaudited financial statements reflect all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the financial
information set forth therein in accordance with accounting principles
generally accepted in the U.S. Operating results for interim periods are not
necessarily indicative of operating results for an entire year. All financial
statement disclosures related to the six months ended June 30, 1999 and 2000
and subsequent to June 30, 2000 are unaudited.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 Use of Estimates

   The preparation of financial statements in conformity with accounting
principles generally accepted in the U.S. requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 Concentrations of Risk

  Credit Risk

   Financial instruments which potentially subject the Company to
concentrations of credit risk include trade accounts receivable and cash
equivalents. The Company manages its credit risk regarding trade accounts
receivable by performing ongoing evaluations of its customers' financial
condition, and maintains an allowance for doubtful accounts for any accounts
that are considered to be uncollectible. The Company has not experienced
material credit losses from its customers.

   The Company invests its excess cash in U.S. government securities and debt
instruments of financial institutions and corporations with strong credit
ratings. The Company has not experienced any significant losses on its cash
equivalents.

  Key Distributor Risk

   The Company is dependent on one distributor for the sale of Duet through an
agreement that is exclusive through August 2002. Any failure by the distributor
to adequately support Duet could have a material adverse effect on the
Company's revenues and profitability.

  Key Suppliers Risk

   The monitors and many components of the test strips used in the Company's
products are manufactured by single source vendors. Any disruptions in supply
or quality problems could have a material adverse impact on the Company's
business and profitability. The Company has not experienced and does not expect
to experience any significant production problems or delays from its vendors.

 Cash Equivalents

   The Company considers cash equivalents to include highly liquid instruments
purchased with maturities of three months or less.

 Inventories

   Inventories are valued at the lower of cost or market, cost being determined
by the first-in, first-out method.

 Property and Equipment

   Property and equipment are stated at cost and are depreciated using the
straight-line method over the estimated useful lives of the assets. The useful
life of furniture and fixtures, production equipment, and research and
development equipment is generally five years, and the useful life of computer
equipment is generally three years. Leasehold improvements are amortized over
the shorter of their estimated useful lives or lease terms. Depreciation
expense was $202,000, $441,000, and $676,000 for the years ended December 31,
1997,

                                LXN CORPORATION

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

1998, and 1999, respectively, and $316,000 and $355,000 for the six months
ended June 30, 1999 and 2000, respectively. Expenditures for maintenance and
repairs are charged to operations as incurred. When assets are retired or sold,
the cost and accumulated depreciation are removed from the respective accounts
and any gain or loss is recognized.

 Long-Lived Assets

   The Company investigates potential impairments of its long-lived assets when
there is evidence that events or changes in circumstances indicate that the
carrying amount of an asset may not be recovered. An impairment loss is
recognized when an asset's fair value, determined based on undiscounted cash
flows expected to be generated by the asset, is less than its carrying amount.
Any required impairment loss would be measured as the amount by which the
asset's carrying value exceeds its fair value, and would be recorded as a
reduction in the carrying value of the related asset and a charge to results of
operations.

 Fair Value of Financial Instruments

   The carrying amount of long-term debt approximates fair value based on
interest rates currently available to the Company for borrowings with similar
terms and maturities because it has a variable interest rate indexed to the
prime rate . The carrying amount of cash equivalents approximates fair value
because of the short maturities of these instruments.

 Revenue Recognition

   The Company recognizes revenue when all of the following criteria have been
met: (1) persuasive evidence of an arrangement exists between the Company and
its customer, (2) the Company has delivered its product to its customer, (3)
the Company's price for the products sold is fixed or determinable, and
(4) collectibility of the sales price is reasonably assured.

   The Company offers certain rights of return to its customers. Because of the
relatively recent introduction of the Company's products and the emerging
nature of the market for such products, the Company lacks sufficient history to
make reliable accurate estimates of product returns at the time of shipment,
Therefore, the Company defers the recognition of revenue until customers'
return rights have expired. In the case of sales to distributors, this occurs
when the distributors have sold through the product to their customers. In the
case of direct sales to medical equipment suppliers and end users, this
generally occurs 30 days after products have been shipped.

   From time to time, the Company offers sales incentives in the form of mail-
in rebates for its products. A provision for estimated rebates is recorded as a
reduction of revenue in the period in which related sales are recognized. No
significant rebates were offered during 1999 or during the first six months of
2000. A provision of $105,000 was made for estimated rebates at December 31,
1998 for point of sale rebates offered with Duet.

   Two customers made up 37% and 8% of total sales for the six months ended
June 30, 2000. The same two customers made up 44% and 28% of total sales in
1999, and 39% and 21% of total sales in 1998.

 Warranty Costs

   The Company provides for the estimated costs that may be incurred under its
warranty programs at the time of recognizing revenue.

 Research and development costs

   Research and development costs are expensed as incurred.

 Employee and director stock-based compensation

   The Company measures compensation expense for its employee and director
stock-based compensation plans using the intrinsic value method and provides
pro forma disclosures of net loss and net loss per share as if a fair value
method had been applied in measuring compensation expense. Accordingly,
compensation cost for stock options is measured as the excess, if any, of the
fair value of the Company's common stock at the date of grant over the amount
the employee must pay to acquire the stock. Stock-based compensation is
amortized over the related vesting periods using an accelerated method in
accordance with Financial Accounting Standards Board Interpretation ("FIN") No.
28, "Accounting for Stock Appreciation Rights and Other Variable Stock Options
or Award Plans." The amount of stock-based compensation expense to be recorded
in future periods could decrease if awards for which accrued but unamortized
compensation expense has been recorded are forfeited.

 Non-employee stock-based compensation

   Stock-based awards issued to non-employees for goods or services are
accounted for using fair value methods and are remeasured to fair value at each
period end until the earlier of the date that performance by the non-employee
is complete or the awards are fully vested.

 Income taxes

   Current income tax expense or benefit is the amount of income taxes expected
to be payable or refundable for the current year. A deferred income tax asset
or liability is computed for the expected future impact of differences between
the financial reporting and tax bases of assets and liabilities and for the
expected future tax benefit to be derived from tax credits and loss
carryforwards. Deferred tax assets are reduced by a valuation allowance when,
in the opinion of management, it is more likely than not that some portion or
all of the deferred tax assets will not be realized.

 Earnings (loss) per share

   Basic loss per share is computed by dividing net loss available to common
stockholders by the weighted average number of common shares outstanding for
the period. Diluted loss per share is computed by dividing net loss available
to common stockholders by the weighted average number of common shares
outstanding during the period increased to include dilutive potential common
shares that were outstanding during the period. The dilutive effect of
outstanding common stock options and preferred stock warrants is reflected in
diluted loss per share by application of the treasury stock method. The Company
has excluded all redeemable convertible preferred stock, outstanding common
stock options, and outstanding preferred and common stock warrants from the
calculation of diluted loss per share for all periods presented because such
securities are antidilutive for these periods.

 Unaudited pro forma balance sheet

   If the IPO contemplated by the Company is consummated as presently
anticipated, each share of redeemable convertible preferred stock outstanding
at the date of the closing will automatically convert into two shares of common
stock. In addition, the Series D and Series E preferred stock warrants are
assumed to be exercised into preferred stock, and then immediately converted
into two shares of common stock, upon the IPO, since they are currently in-the-
money and expire upon the closing of the IPO if unexercised. The unaudited pro
forma balance sheet as of June 30, 2000 reflects the conversion of the
preferred stock and the exercise and conversion of the preferred stock warrants
as if such conversion and exercise had occurred as of June 30, 2000. This would
have resulted in the conversion of the preferred stock outstanding at that
date, as well as the 358,799 shares of Series F preferred stock issued in
October 2000 (Note 13), into 8,018,686 shares of common stock, and the
conversion of the preferred stock warrants outstanding at that date into
845,832 shares of common stock.

 Recently issued accounting pronouncements

   In June 1998, the Financial Accounting Standards Board, or FASB, issued
Statement of Financial Accounting Standards No. 133 (SFAS 133), "Accounting for
Derivative Instruments and Hedging Activities," which establishes accounting
and reporting standards for derivative instruments and hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities on the balance sheet and measure those instruments at fair value.
SFAS 133 as amended by SFAS 137, "Accounting for Derivative Instruments and
Hedging Activities-Deferral of the Effective Date of SFAS 133," an amendment of
SFAS 133, is effective for fiscal years beginning after June 15, 2000. To date,
the Company has not engaged in derivative or hedging activities.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin 101, "Revenue Recognition," or SAB 101, which provides
guidance on the recognition, presentation and disclosure of revenue in
financial statements filed with the SEC. SAB 101 outlines the basic criteria
that must be met to recognize revenue and provides guidance for disclosure
related to revenue recognition policies. The adoption of the principles of SAB
101 has not had a significant impact on the Company's financial statements.

   In March 2000, the FASB issued FASB Interpretation No. 44 (FIN 44),
"Accounting for Certain Transactions Involving Stock Compensation, an
Interpretation of APB 25." FIN 44 clarifies the definition of an employee for
purposes of applying APB 25; the criteria for determining whether a stock
option or award plan qualifies as a non-compensatory plan; the accounting
consequences of various modifications to the terms of a previously fixed stock
option or award; and the accounting for an exchange of stock compensation
awards in a business combination. FIN 44 became effective on July 1, 2000, with
certain provisions effective earlier. The Company does not expect FIN 44 to
have a significant impact on its financial statements.

   In August 2000, the FASB Emerging Issues Task Force ("EITF") issued EITF 00-
14, "Accounting for Certain Sales Incentives," which addresses the recognition,
measurement and classification for sales incentives offered voluntarily by
vendors without charge to customers. The Company's accounting policy for sales
incentives is in compliance with EITF 00-14.

loan. The promissory note evidencing the term loan provides for monthly
principal payments of $35,000 and interest payments at the bank's prime rate
plus one-half percentage point. The Company owed $1,371,000 and $1,160,000 at
December 31, 1999 and June 30, 2000, respectively, on the term loan. As of June
30, 2000, the interest rate on the promissory note was 10%. The credit
agreement is

   The 1999 credit agreement, as amended in March 2000, also provides for a
$500,000 line of credit through March 21, 2001 for equipment purchases only.
The interest rate for advances on the equipment line of credit is the same as
the term loan above. Interest only is due monthly through September 21, 2000,
and the outstanding principal balance is payable in 30 equal payments of
principal plus accrued interest beginning October 21, 2000. The Company took no
advances on the equipment line of credit during 1999. At June 30, 2000,
$500,000 was outstanding on the equipment line of credit. The 1999 credit
agreement also provides for a $1,000,000 line of credit based on the Company's
accounts receivable. The interest rate for advances on the accounts receivable
line of credit is the bank's prime rate, and advances are payable upon the
earlier of March 21, 2001 or a demand from the bank. The Company took no
advances on the accounts receivable line of credit during 1999 or the six
months ended June 30, 2000.

   As consideration for extending the 1999 credit agreement, the Company issued
a five-year warrant to purchase 5,384 shares of common stock at $5 per share in
May 2000. The fair value of the warrant on the date of issuance was $51,000 and
was recorded as a deferred facility fee and amortized to interest expense over
the life of the agreement. The fair value was determined by management using
the Black-Scholes option pricing model with the following assumptions: 5 year
contractual life, 6.65% risk-free interest rate, 60% expected volatility, and
0% expected dividend yield.

   The 1999 credit agreement, as amended, contained performance covenants
requiring the Company to maintain a minimum quick ratio, incur no more than a
maximum quarterly loss, and to raise a minimum of $3,000,000 of equity by
September 30, 2000. The Company was in default of the maximum quarterly loss
covenant at December 31, 1999, and was in default of both the minimum quick
ratio and the maximum quarterly loss covenants at June 30, 2000. The bank
waived compliance with these defaulted covenants as of December 31, 1999 and
June 30, 2000. The 1999 credit agreement with the bank also restricts the
Company from declaring or paying any dividends, or from making any other
distribution of capital stock.

   In October 2000, the 1999 credit agreement was further amended to modify
certain performance covenants. The Company was in default of certain of these
covenants at October 16, 2000. As a result, the entire remaining principal
balances of the bank credit facilities have been classified as current
liabilities.

   In October 2000, as consideration for amending the 1999 credit agreement,
the Company issued a five-year warrant to the bank to purchase 6,000 shares of
common stock at $5 per share. The fair value of the warrant on the date of
issuance was estimated by management to be $69,000 and was recorded as a
deferred facility fee and amortized to interest expense over the life of the
agreement. The fair value was estimated using the Black-Scholes option pricing
model with the following assumptions: 5 year contractual life, 5.85% risk-free
interest rate, 60% expected volatility, and 0% expected dividend yield.

5. Common Stock

   The holders of common stock are entitled to noncumulative dividends if and
when such dividends are declared by the Company's board of directors.

6. Redeemable Convertible Preferred Stock

 Rights and Preferences

   The holders of all series of convertible preferred stock are entitled to
noncumulative dividends if and when such dividends are declared by the
Company's board of directors, and have the same voting rights as the common
stockholders.

   Upon a liquidation, dissolution, or winding up of the Company, including a
consolidation or merger with another company, a sale of more than 50% of the
Company's common stock or the sale of substantially all of the assets of the
Company, the holders of all series of preferred stock have a preference in
liquidation over the common stockholders. The liquidation value for all series
of preferred stock is the sum of the issuance price plus an amount equal to all
declared but unpaid dividends (subject to appropriate adjustment in the event
of any stock dividend, stock split, combination, or other similar
recapitalization affecting such shares). The Series E preferred stock has
preference in liquidation over the Series A, B, C and D preferred stock and the
common stock. If the assets of the Company are not sufficient to fulfill the
liquidation amount, the preferred stockholders will share in the distribution
of the assets on a pro rata basis based on the liquidation amount.

   The Series E preferred stock is redeemable upon a majority vote of the
holders after the earlier of five years from the issue date or failure by the
Company to meet its obligations to the holders of Series E preferred stock.

   All series of preferred stock are convertible into common stock, at the
option of the holder, on a two-for-one basis, subject to adjustment for
dilution. Additionally, all series of preferred stock will automatically
convert into common stock concurrent with the closing of an underwritten public
offering of common stock under the Securities Act of 1933 in which the Company
receives at least $25 million in net cash proceeds and the price per share is
at least $10.00, subject to adjustment for dilution. The Company has reserved
11,390,492 shares of common stock for issuance upon conversion of the preferred
stock.

   Because the redemption of all series of preferred stock is outside of the
control of the Company, the preferred stock and related preferred stock
warrants have been classified on the balance sheets as redeemable securities.

 Preferred Stock Warrants

   In connection with the Series D preferred stock offering in 1997, the
Company issued to a consultant warrants to purchase 20,000 shares of Series D
preferred stock at $12.50 per share in exchange for services related to this
transaction. Such warrants may be exercised at any time prior to the earlier of
September 2002 or the closing of an underwritten public offering of common
stock under the Securities Act of 1933, but not thereafter. The aggregate fair
value of these warrants at their grant date was determined by management to be
$100,000 and was recorded as issuance costs. The fair value of the warrants was
determined using the Black-Scholes option pricing model with the following
assumptions: 5 year contractual life, 6.00% risk-free interest rate, 40%
expected volatility, and 0% expected dividend yield.

   In connection with the Series E preferred stock offering in 1999, the
Company issued to the Series E investors warrants to purchase 402,916 shares of
Series E preferred stock at $13.00 per share. Such warrants may be exercised at
any time prior to the earlier of five years from the issue date or the closing
of an underwritten public offering of common stock under the Securities Act of
1933, but not thereafter. The

proceeds from the sale of the Series E preferred stock were allocated between
the preferred stock and the warrants based on their relative fair values. The
separate fair value of the warrants was determined by management using the
Black-Scholes option pricing model with the following assumptions: 5 year
contractual life, 5.50% risk-free interest rate, 40% expected volatility, and
0% expected dividend yield. The Series E preferred stock is being accreted to
its redemption value of $10,176,000 over a period of five years.

7. Stock-Based Compensation

   Under the 2000 Equity Incentive Plan (the "Plan"), 1,600,000 shares of the
Company's common stock are reserved for issuance pursuant to stock options. In
October 2000, the board of directors increased the number of shares reserved
for issuance under the Plan to 2,400,000 shares. Incentive stock options may be
granted to employees, while nonstatutory stock options may be granted to
employees, directors, and consultants to the Company. The Plan is administered
by the board of directors and provides generally that, for incentive stock
options, the exercise price must not be less than the fair value of the
Company's common stock at the date of grant and, for nonstatutory stock
options, the exercise price must not be less than 85% of the fair value of the
Company's common stock at the date of grant. Options granted under the Plan
generally vest ratably over four years and are exercisable for a period of ten
years from the date of the grant.

   The following table summarizes stock option activity under the Plan:

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   At December 31, 1999, the Company has federal and California net operating
loss carryforwards of approximately $27,800,000 and $13,733,000 respectively,
which amounts expire beginning in 2008 and 2000, respectively. The difference
between the federal and California tax loss carryforwards is attributable to
the capitalization of research and development expenses for California tax
purposes. The Company also has federal and California research and development
tax credit carryforwards of approximately $325,000 and $281,000 respectively,
which begin expiring in 2008.

   Pursuant to Sections 382 and 383 of the Internal Revenue Code, annual use of
the Company's net operating loss and credit carryforwards may be limited due to
changes in the Company's stock ownership of more than 50%. As a result of

 Licensing Agreement

   During 1997, the Company entered into a licensing agreement with a
pharmaceutical company under which it obtained a non-exclusive license to
technology. The Company is required to make royalty payments ranging from the
lower of (1) from 4% to 7% of sales dollars or (2) from $.05 to $.12 per unit
of fructosamine products sold, as defined in the agreement. The Company
incurred royalty expense of $23,000 and $28,000 under this agreement during the
years ended December 31, 1998 and 1999, respectively, and $16,000 and $16,000
during the six months ended June 30, 1999 and 2000, respectively. This expense

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


11. Employee Benefit Plan

   In 1998, the Company established a voluntary deferred compensation plan
under Section 401(k) of the Internal Revenue Code. Eligible participants may
contribute portions of their salaries to the plan subject to IRS limits.
Company matching contributions are made on a discretionary basis, and vest
ratably over three years. The Company made contributions of $9,000 and $15,000
during the years ended December 31, 1998 and 1999, respectively, and $11,000
and $7,000 during the six months ended June 30, 1999 and 2000, respectively.

12. Technology License Agreement

   The Company has granted a third party a non-exclusive, worldwide license to
manufacture, distribute, market and sell certain technology developed by the
Company. The Company received $100,000 upon the commencement of the agreement.
The agreement calls for royalty payments to be made to the Company based on a
percentage of net revenues on the licensed technology sold by the third party.
The Company is guaranteed minimum royalties of $200,000 each year through 2004.
The Company records revenue, classified as other income, when due as there is
no future involvement or obligation due on the part of the Company. The
agreement expires in 2008.

13. Subsequent Financing

   In August and September 2000, the Company entered into convertible
promissory notes with an aggregate principal amount of $2,500,000. The notes
provided for interest payments at 8% per annum. In addition, the holders of the
notes received warrants to purchase 17,861 shares of Series F preferred stock
at a purchase price of $14 per share. The fair value of the warrants on the
date of issuance was estimated by management to be $379,000 and was recorded as
debt issuance costs and amortized to interest expense over the life of the
notes. The fair value was estimated using the Black-Scholes option pricing
model with the following assumptions: 5 year contractual life, 5.85% risk-free
interest rate, 60% expected volatility, and 0% expected dividend yield.

   In October 2000, the Company issued 178,569 shares of Series F redeemable
convertible preferred stock at a price of $14 per share for total gross
proceeds of $2,500,000. Upon the completion of the Series F preferred stock
financing, the outstanding convertible promissory notes and unpaid accrued
interest thereon automatically converted into 180,230 shares of Series F
preferred stock. The holders of Series F preferred stock have rights and
privileges identical to those of the holders of Series E preferred stock as
disclosed in Note 6. The Company will record a charge for the beneficial
conversion feature embedded in these securities in October 2000. The value of
the beneficial conversion feature was measured using its intrinsic value, i.e.,
the excess of the aggregate fair value of the common stock into which the
Series F preferred stock is convertible over the proceeds allocated to the
security. The intrinsic value of the beneficial conversion feature of
approximately $5.8 million exceeded the proceeds allocated to the Series F
preferred stock of approximately $4.6 million; therefore, the Company limited
recognition of the beneficial conversion feature to the approximately $4.6
million proceeds allocated to the Series F preferred stock. The Company
accreted the entire amount of the beneficial conversion feature at the date of
issuance because the Series F preferred stock is immediately convertible.

Item 17. Undertakings

   The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of LXN pursuant
to provisions described in Item 14 or otherwise, we have been advised that in
the opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by us of expenses incurred or paid by a director, officer or
controlling person

                                      II-3
<PAGE>

of LXN in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the
securities being registered, we will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

   The undersigned Registrant hereby undertakes:

     (1) That, for purposes of determining any liability under the Securities
  Act, each filing of the registrant's annual report pursuant to Section
  13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of
  an employee benefit plan's annual report pursuant to Section 15(d) of the
  Exchange Act) that is incorporated by reference in the registration
  statement shall be deemed to be a new registration statement relating to
  the securities offered therein and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

     (2) That, for purposes of determining any liability under the Securities
  Act, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

     (3) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof
