OVERVIEW

    THIS REPORT CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES RELATING TO THE FUTURE FINANCIAL PERFORMANCE OF CYGNUS, INC.
("CYGNUS," "THE COMPANY," "WE," "OUR," OR "US"), AND ACTUAL EVENTS OR RESULTS
MAY DIFFER MATERIALLY. IN EVALUATING SUCH STATEMENTS, STOCKHOLDERS AND INVESTORS
SHOULD SPECIFICALLY CONSIDER THE VARIOUS FACTORS IDENTIFIED UNDER THE CAPTION
"RISK FACTORS" CONTAINED IN THE MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS THAT COULD CAUSE ACTUAL RESULTS TO
DIFFER MATERIALLY FROM THOSE INDICATED BY SUCH FORWARD-LOOKING STATEMENTS. WE
UNDERTAKE NO OBLIGATION TO PUBLICLY RELEASE THE RESULTS OF ANY REVISIONS TO
THESE FORWARD-LOOKING STATEMENTS WHICH MAY BE MADE TO REFLECT EVENTS OR
CIRCUMSTANCES AFTER THE DATE HEREOF OR TO REFLECT THE OCCURRENCES OF
UNANTICIPATED EVENTS.

    We are engaged in the development and manufacture of diagnostic medical
devices, utilizing proprietary technologies to satisfy unmet medical needs cost
effectively. Our current efforts are focused on a frequent, automatic and
non-invasive glucose monitoring device, the GlucoWatch-Registered Trademark-
biographer, and enhancements thereto.

    Cygnus was incorporated in California in 1985 and was merged into a Delaware
corporation in September 1995. Our principal executive offices are located at
400 Penobscot Drive, Redwood City, California 94063, our telephone number at
that address is (650) 369-4300 and our facsimile number at that address is (650)
369-5318. Additionally, our website is www.cygn.com.

    On July 9, 1999, John C Hodgman, President and Chief Executive Officer,
succeeded Gary W. Cleary, Ph.D., as Chairman of the Board of Directors. (Dr.
Cleary resigned as Chief Technical Officer effective the same date.) Dr. Cleary
served as Chairman Emeritus of the Board from July 9, 1999 until February 22,
2000, when he resigned from the Board of Directors.

CYGNUS' BUSINESS STRATEGY

    In 1999 we chose to focus solely on glucose monitoring systems and sold our
drug delivery business to Ortho-McNeil Pharmaceutical, Inc., a Johnson & Johnson
company. Our GlucoWatch-Registered Trademark- system represents a potential
advance in glucose monitoring technology as compared to the currently prevailing
"finger stick" blood monitoring methods. The GlucoWatch system is designed to
measure glucose frequently, automatically and non-invasively through the ease
and convenience of a device worn like a wristwatch. Worldwide sales of blood
glucose self-monitoring products were approximately $2.5 billion in 1997 (Boston
Biomedical Consultants, Inc.). More than forty million people in North America,
Europe, Japan and Korea have diabetes. In the United States alone, more than ten
million people have been diagnosed with diabetes, with another five million
believed to have the condition. The number of people with diabetes is expected
to continue to grow with the aging of the population, while the number of
diagnosed cases is also expected to increase with changes in diagnostic
standards and new diagnostic technologies.

    Clinical studies sponsored by the National Institutes of Health (NIH)
indicate that better management of glucose levels through more frequent testing
and more frequent insulin injections would enable people with diabetes to reduce
or significantly delay many serious diabetes-related

                                       1
<PAGE>
health complications. However, largely due to the pain of repetitive finger
sticking and the associated disruption of daily life, most people with diabetes
currently test their glucose levels less than half as often as recommended,
resulting in limited glucose information to make decisions that could better
control glucose fluctuations. We believe this lack of information presents a
significant unmet need for a new type of glucose monitoring device.

    To address this unmet need, our GlucoWatch system provides frequent,
automatic and non-invasive glucose measurements and is intended for detecting
trends and tracking patterns of glucose levels in adults, 18 years and older,
who have diabetes. The device is intended for use at home and in healthcare
facilities to supplement, not replace, information obtained from standard home
blood glucose monitoring devices. Following a three-hour warm-up period and
calibration from a finger stick blood measurement, the device is capable of
providing up to thirty-six non-invasive glucose measurements over twelve hours.
The extracted glucose is collected in a consumable component called the
AutoSensor, which is attached to the back of the biographer and replaced after
twelve hours of measurements. The GlucoWatch system (i.e., the biographer and
AutoSensor ) offers features such as alerts indicating hypoglycemic and
hyperglycemic conditions, and event markers that record factors affecting
glucose levels.

    On December 6, 1999, we announced that our Premarket Approval application
(PMA) for the GlucoWatch system received a unanimous recommendation for approval
with conditions by the United States Food and Drug Administration's (FDA)
Clinical Chemistry and Clinical Toxicology Devices Panel of the Medical Devices
Advisory Committee. The Advisory Committee suggested three conditions for
approval. The first is the creation of an education program, about which we have
already been in discussions with the FDA concerning the substance of such a
program. The second condition is that our product labeling will be revised in
accordance with recommendations given to the FDA by the Committee, and we are
currently in discussions with the FDA on proposed labeling. Third, the Committee
suggested a post-market study of detection of hypoglycemia and hyperglycemia.
This lattermost condition does not need to be satisfied prior to FDA approval.
Although the FDA is not bound by the decisions of the Advisory Committee, the
agency typically follows its advisory committees' advice. By way of background,
our 5,000-page PMA application included analyses of clinical studies conducted
on more than 600 people with diabetes, who used the device from a few hours to
up to six weeks. The studies, which were performed at more than 15 clinical
sites across the United States, involved over 25,000 hours of use of the
GlucoWatch system. The participants consisted of a cross-section of racial and
age groups, diabetes types (both type 1 and type 2), and other defining
characteristics. Approximately 19,000 paired data points were generated from the
studies, comparing interstitial fluid glucose measurements obtained by the
GlucoWatch system to glucose measurements obtained with finger stick monitors
using capillary blood.

    On December 2, 1999, we announced the receipt of a CE Certificate for the
GlucoWatch system, indicating that the product has met the essential
requirements and other criteria of the European Community Directive 93/42/ECC,
Annex V, Section 3.2. The CE Certificate is required for selling products in the
European Community. We are compliant with ISO 9002 and EN 46002.

    In December 1999, we entered into a five-year Supply Agreement with Hydrogel
Design Systems, Inc. relating to the manufacture of the AutoSensor hydrogel
laminate used in the GlucoWatch system. Also, in December 1999, we entered into
a three-year Supply Agreement with Key Tronic Corporation relating to the
manufacture of the biosensor component of the AutoSensor.

                                       2
<PAGE>
Both of these agreements contain percentage minimum requirements of product that
we must purchase from these companies if and when the GlucoWatch system is
commercialized. Additionally, we are currently in negotiations with a
third-party manufacturer for the GlucoWatch system.

    In September 1999, we were awarded a six-month Phase I Small Business
Innovative Research Grant for "High Performance Biosensor Electrode Materials"
from the National Institute of Diabetes and Digestive and Kidney Diseases
division of the National Institutes of Health (NIH) in the amount of
$0.1 million. This funding is used to investigate advancements in biosensor
materials used for glucose detection and measurement, potentially to include in
future versions of the GlucoWatch system.

    In June 1998, we entered into long-term agreements with E.I. du Pont de
Nemours & Company ("DuPont") for the development and supply of thick film
materials for our GlucoWatch system. In July 1997, we entered into a Product
Supply Agreement with Contract Manufacturing, Inc. relating to the assembly of
the AutoSensor and also the final packaging of the GlucoWatch system starter
kits. This latter agreement continues for five years from date of first
commercial sale, and contains minimum requirements of product that we must
purchase from this company if and when the GlucoWatch system is commercialized.

    In 1996, we entered into a collaboration agreement with Yamanouchi
Pharmaceutical Co., Ltd. for the commercialization of the GlucoWatch system in
Japan and Korea, and also a collaboration agreement with Becton Dickinson &
Company for the commercialization of the GlucoWatch system in the rest of the
world. Under the Yamanouchi agreement, we are eligible to receive milestone
payments prior to commercialization and to receive a percentage of the product's
future commercial success in Japan and Korea. In March of 1998, we announced the
termination of our agreement with Becton Dickinson. One of our priorities is to
establish an alliance or alliances for the commercialization of the GlucoWatch
system in North America and Europe. The purpose of such an alliance or alliances
is for us to secure certain commercialization functions, such as distribution,
sales and customer service. We are in discussions with several companies
regarding this objective. Some of the companies are international in scope and
would provide the requisite commercialization functions worldwide. Other
companies focus on certain geographies and/or certain commercialization
functions. The potential signing of a worldwide commercialization agreement may
or may not coincide with the launch of our GlucoWatch system, assuming we
receive FDA approval. We are evaluating out-sourced capabilities for a U.S.
launch without a worldwide commercialization alliance. There can be no assurance
that we will be able to enter into a commercialization alliance or alliances or
that we will be able to out-source certain commercialization capabilities for
launch without a worldwide commercialization alliance in place.

    In 1995, we entered into an exclusive license agreement with The Regents of
the University of California to patents and patent applications relating to
devices for iontophoretic non-invasive sampling of substances. Under this
license, if our GlucoWatch system is commercialized and is covered by the scope
of the license, we will pay the University of California certain royalties.

SALE OF OUR TRANSDERMAL DRUG DELIVERY SYSTEMS

    On December 15, 1999, we completed the sale of substantially all of our drug
delivery business assets to Ortho-McNeil Pharmaceutical, Inc., a Johnson &
Johnson company. The transaction was

                                       3
<PAGE>
finalized upon receiving clearance under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976. We sold all of the assets of our drug delivery
business to Ortho-McNeil except those relating to a nicotine patch under
development and one other early- stage project, both of which were terminated
before year end.

    Cygnus products that were sold to Ortho-McNeil include certain assets
related to the Nicotrol-Registered Trademark- (Pharmacia AB, Stockholm, Sweden)
nicotine system (currently marketed by Pharmacia & Upjohn in Europe and by
McNeil Consumer Healthcare, a Johnson & Johnson company, in the U.S.); two
hormone replacement transdermal products (a 7-day estrogen patch recently
approved by the U.S. Food and Drug Administration and an estrogen/progestin
combination product that completed Phase III clinical trials); and the EVRA-TM-
(Johnson & Johnson, New Brunswick, New Jersey) contraceptive patch we were
developing with the R.W. Johnson Pharmaceutical Research Institute.

    Under the terms of the agreement with Ortho-McNeil, we received $20 million
in cash at closing, and Ortho-McNeil will pay up to an additional $55 million in
cash, contingent on the achievement of certain milestones. The contingent
payments relate to the achievement by Ortho-McNeil of certain technical,
regulatory and commercialization milestones related to the EVRA transdermal
contraceptive patch. We are eligible to receive up to $14.8 million of these
contingent milestones in the year 2000; however, because the achievement of
these milestones is not within our control, we cannot predict the likelihood or
timing of these contingent payments in the year 2000 and beyond.

    The Final Award in an arbitration matter between Sanofi, S.A. and Cygnus
relating to transdermal hormone replacement therapy systems, however, remained
with Cygnus and is not part of the Ortho-McNeil sale. This Final Award was
entered as a judgment of the U.S. District Court for the Northern District of
California on December 11, 1997. Cygnus' obligations under the Final Award are
as follows: (i) the $14.0 million cash payment already made by Cygnus to Sanofi
in January 1998, (ii) payments of an aggregate amount equal to $17.0 million,
commencing in 2001 and ending in 2005, and (iii) a convertible promissory note
in the principal amount of $6.0 million, issued in December 1997, payable in
full at the end of four years and bearing interest at 6.5% per annum. (The note
will be convertible into our Common Stock at Sanofi's option, exercisable at any
time during the four year term, at a conversion rate of $21.725 per share.) The
underlying agreement, which was the subject matter of the arbitration, was
terminated on December 15, 1999.

    The primary reason for selling the drug delivery business was to focus
management attention and corporate resources on our glucose monitoring business.
We will use the proceeds to accelerate commercialization activities for the
GlucoWatch system.

OUR FREQUENT, AUTOMATIC AND NON-INVASIVE GLUCOSE MONITORING SYSTEMS

MARKET OPPORTUNITY

    People with diabetes measure blood glucose levels to adjust their diet,
medication and insulin use to better control their glucose levels in order to
prevent diabetes-related complications. Currently, to measure their glucose
levels, people with diabetes must prick their fingers, draw blood and place a
drop of blood on a glucose reagent strip inserted in an instrument that provides
a glucose reading. Each day of testing can involve numerous sticks and the
complete procedure is not only painful but disruptive to daily life. As a result
of this pain and disruption, most people with diabetes

                                       4
<PAGE>
monitor their blood glucose levels less than twice per day, instead of the
recommended four to seven times per day. Even at the recommended level of
testing, the market for products for self-monitoring of glucose levels by people
with diabetes is quite substantial.

    Worldwide sales of products for the self-monitoring of blood glucose levels
were approximately $2.5 billion in 1997. Approximately 80% to 90% of the sales
were related to disposable glucose reagent strips for finger stick monitoring
(Boston Biomedical Consultants, Inc.). In the U.S., a majority of glucose level
testing is conducted by a relatively small segment of people with diabetes; for
example, of these people, just 19% (about 1.6 million) account for 52% of the
tests performed. The number of people diagnosed with diabetes has been growing
and is expected to continue to grow due to the aging of the population, changes
in diagnostic standards and new diagnostic technologies. Specifically, the
diagnostic standards in the U.S. have been changed such that a fasting plasma
glucose value of greater than or equal to 126 mg/dL now indicates a diagnosis of
diabetes, whereas such diagnosis previously required a value of greater than or
equal to 140 mg/dL. Diabetes can lead to severe complications over time,
including blindness, loss of kidney function and peripheral neuropathy, causing
circulation problems to the arms and legs, pain and potential amputation. The
American Diabetes Association (ADA) estimated that the complications arising
from diabetes cost the U.S. healthcare system in excess of $45 billion in 1992.
These complications are largely a consequence of years of poor management of
glucose levels by people with diabetes. Results of the Diabetes Control and
Complication Trial, a major clinical trial sponsored by the National Institutes
of Health and published in 1993, showed that more frequently monitored blood
glucose levels and rigid adherence to a program of diet, exercise and insulin
injections could prevent or significantly delay the onset of many of the
long-term complications of diabetes.

THE GLUCOWATCH-REGISTERED TRADEMARK- SYSTEM

    We believe that there is an unmet need for automatic, frequent and
non-invasive glucose monitoring. In an effort to address this unmet need, we
have developed the GlucoWatch biographer, which is worn like a wristwatch and,
after calibrating each new AutoSensor with a standard blood glucose monitor,
automatically extracts and measures glucose levels through intact skin
approximately every twenty minutes. The durable GlucoWatch biographer displays
and stores current and past glucose levels and trend data. The extracted glucose
is collected in a consumable AutoSensor attached to the back of the device and
replaced after twelve hours of readings. The GlucoWatch system offers, in a
portable and discreet device, features not available in currently marketed
devices. These include frequent data collection, electronic memory to store and
display glucose levels, alerts indicating hypoglycemic and hyperglycemic
conditions and event markers that record factors that affect glucose levels. The
GlucoWatch biographer is designed to be worn day and/or night for glucose
monitoring, and is expected to reduce significant drawbacks of the finger stick
technique, such as the pain of repetitive sticking and the disruption of normal
activities caused by cumbersome procedures. We believe that the GlucoWatch
system can provide additional information that can help people with diabetes
understand fluctuations in their glucose levels.

    Specifically, our GlucoWatch system extracts glucose molecules through
intact skin utilizing a patented sampling process called electro-osmosis (or
"reverse iontophoresis"). The glucose is extracted from interstitial fluid, not
blood, and is collected and measured by the consumable AutoSensor, which
includes an enzyme-containing hydrogel and electrodes for electro-osmotic

                                       5
<PAGE>
extraction and biosensing. The glucose collected in the AutoSensor triggers an
electro-chemical reaction in the AutoSensor, generating electrons. The biosensor
measures the electrons and an application-specific integrated circuit ("ASIC")
in the GlucoWatch system equates the number of electrons to a concentration of
blood glucose. The GlucoWatch system automatically measures glucose levels at
twenty-minute intervals, and displays the most recent readings and trends at the
push of a button. Its electronic memory capabilities permit the retrieval of
past data, allowing longer-term trend analysis. Additionally, we are developing
future generation glucose monitoring products, as well as enhancements to the
GlucoWatch system. Such enhancements include, but are not limited to, features
for increased user convenience such as a shorter warm-up period, extension of
the AutoSensor measurement duration beyond twelve hours, an increase in the
number of glucose measurements per hour, addition of a delayed start feature,
and personal computer linkages for downloading data, as well as various cost
reductions in the manufacturing process. Other enhancements are also under
consideration. We are in the early developmental stages for a future telemetric
product that allows both greater flexibility in the location of the glucose
extraction component and a new form of the monitor that stores and displays
glucose data.

REGULATORY STATUS

    On January 25, 1999, we submitted the first part of our PMA for the
GlucoWatch system to the FDA. This submission included a variety of information,
including manufacturing documentation. We submitted the remainder of the PMA in
June 1999, including analysis of a series of clinical studies totaling more than
600 people with diabetes, at more than 15 clinical sites across the U.S., who
used our biographer from a few hours to up to six weeks, as well as two
additional studies. The participants in our clinical studies consisted of a
cross-section of racial and age groups, diabetes types (both type 1 and type 2),
and other defining characteristics. This represented over 25,000 hours of use of
the GlucoWatch biographer. Approximately 19,000 paired data points were
generated from the studies, comparing glucose measurements obtained by the
GlucoWatch biographer to glucose measurements obtained with finger stick
monitors using capillary blood. In July 1999, the FDA notified Cygnus that our
PMA was deemed suitable for filing and was granted expedited review status. On
December 6, 1999, our PMA for the GlucoWatch biographer received a unanimous
recommendation for approval with conditions by the FDA's Clinical Chemistry and
Clinical Toxicology Devices Panel of the Medical Devices Advisory Committee. The
Advisory Committee suggested three conditions for approval. The first is the
creation of an education program, about which we have already been in discussion
with the FDA concerning the substance of such a program. The second condition is
that our product labeling will be revised in accordance with recommendations
given to the FDA by the Committee, and we are currently in discussions with the
FDA on proposed labeling. Third, the Committee suggested post-market study of
detection of hypoglycemia and hyperglycemia. This lattermost condition does not
need to be satisfied prior to FDA approval. Although the FDA is not bound by the
decisions of the advisory committee, the agency typically follows its Advisory
Committees' advice; however, no assurance can be given that the FDA will approve
our GlucoWatch biographer and we cannot predict the timing of such approval, if
given.

    Furthermore, we are in the process of preparing an Investigational Device
Exemption (IDE) for filing with the FDA so that we can conduct clinical trials
on an ongoing basis. We also anticipate commencing clinical trials with children
and adolescents if the IDE is obtained.

                                       6

COMPETITION

    The glucose monitoring market is highly competitive. Currently the market is
dominated by finger stick blood glucose monitoring products sold by a few major
companies. These companies have established products and distribution channels.
Finger stick glucose monitoring presents a number of barriers to generating more
frequent blood glucose measurements, including the pain of repetitive finger
sticking and the disruption of normal activities, as often people with diabetes
do not want to go through the finger stick process in public. Several companies
are developing alternative invasive, semi-invasive, minimally invasive or
non-invasive methods to monitor glucose levels in a less painful or painless
manner, as well as on a continuous or continual basis. Companies are attempting
to develop a variety of methods to extract interstitial fluid and measure the
glucose concentration therein. Another technology that some companies are
pursuing is the use of infrared spectroscopy, which uses radiation to measure
glucose levels. We are not aware of any products under development that offer
the range of potential benefits of the GlucoWatch system. However, there can be
no assurance that other products will not be more accepted in the marketplace
than the GlucoWatch system or will not render our devices uncompetitive or
obsolete. A number of companies have developed or are seeking to develop new
drugs to treat diabetes that could reduce demand for glucose monitoring systems.
In addition, many of our competitors and potential competitors have
substantially greater resources, research and development staffs and facilities
than we do and have significantly greater experience in developing,
manufacturing and marketing glucose monitoring devices. Competition within the
glucose monitoring industry could also result in price reductions for glucose
monitoring devices such that we may not be able to sell the GlucoWatch system at
a price level adequate for us to realize a return on our investment.

DEPENDENCE ON NEW PRODUCTS; UNCERTAINTY OF MARKET ACCEPTANCE

    For Cygnus to be successful, we will need to continue to develop glucose
monitoring products that address the needs of people with diabetes. Enhanced
glucose monitoring products based on our technologies are currently under
development. In addition, we will be evaluating new products outside of the
glucose monitoring field that can utilize our diagnostic technologies. These
products will require significant additional development and investment,
including preclinical and clinical testing, prior to their commercialization.
From time to time, we have experienced delays or setbacks in the development of
certain of our products. For example, in the past, we experienced development
delays in the miniaturization of the GlucoWatch biographer. There can be no
assurance that we will be able to successfully address problems that may arise
during the development and commercialization process. In addition, there can be
no assurance that the GlucoWatch system, its enhancements or future products can
or will be successfully developed, prove to be safe and effective in clinical
trials, meet applicable regulatory standards, be capable of being manufactured
in commercial quantities at a reasonable cost, be marketed successfully or
achieve market acceptance. If any of our development programs are not
successfully completed, required regulatory approvals or clearances are not
obtained, or products for which approvals or clearances are obtained are not
commercially successful, our business, financial condition and results of
operations could be materially adversely affected.

    Our business is subject to the risks inherent in the development of new
products using new technologies and approaches. There can be no assurance that
unforeseen problems will not develop with these technologies or applications,
that we will be able to successfully address technological

                                       7
<PAGE>
challenges we encounter in our research and development programs or that we will
be able to develop commercially feasible products.

GOVERNMENT REGULATION; NO ASSURANCE OF REGULATORY APPROVALS

    The design, manufacturing, labeling, distribution and marketing of our
products are subject to extensive and rigorous government regulation in the U.S.
and certain other countries where the process of obtaining and maintaining
required regulatory clearance or approvals is lengthy, expensive and uncertain.
In order for us to market our products in the U.S., we must obtain clearance or
approval from the FDA after clinical trials. To date, we have two products which
have received FDA approval; however, these were both in the drug delivery
business that has since been sold to Ortho-McNeil Pharmaceutical, Inc. For the
initial GlucoWatch system, we filed a PMA with the FDA. We anticipate that, if
and when enhancements are added and/or manufacturing processes are modified in
cost-effective ways, we will file one or more supplements to this PMA. We cannot
assure you that these supplements will be approved or that we will not have to
file a new PMA for future enhancements and products. The time required for
regulatory approval of our products after filing is uncertain. There can be no
assurance that problems will not arise that could delay or prevent the
commercialization of our products or that the FDA and foreign regulatory
agencies will be satisfied with the results of clinical trials or approve the
marketing of any products. Moreover, even if regulatory approval is granted,
such approval may include significant limitations on indicated uses for which
any such products could be marketed.

    A medical device and its manufacturer are subject to continual review after
approval, and later discovery of previously unknown problems with a product or
the manufacturing process may result in restrictions on such product or the
manufacturer, including withdrawal of the product from the market. Failure to
comply with applicable regulatory requirements may, among other things, result
in fines, suspensions of regulatory approvals, product recalls, operating
restrictions and criminal prosecution. In addition, new government regulations
may be established that could delay or prevent regulatory approval of our
potential products. We are also subject to federal, state and local regulations
regarding work place safety, environmental protection and hazardous material
controls, among others.

    In order for us to market our products in Europe, Japan and certain other
foreign jurisdictions, we and any of our distributors and agents must obtain
required regulatory registrations or approvals and otherwise comply with
extensive regulations regarding safety, efficacy and quality in those
jurisdictions. Specifically, certain foreign regulatory bodies have adopted
various regulations governing product standards, packaging requirements,
labeling requirements, import restrictions, tariff regulations, duties and tax
requirements. These regulations vary from country to country. Failure to receive
foreign regulatory approvals could have a material adverse effect on our
business, financial condition and results of operations. There can be no
assurance that we will obtain any other required regulatory registrations or
approvals in such countries or that we will not be required to incur significant
costs in obtaining or maintaining such regulatory registrations or approvals.
Delays in obtaining any registrations or approvals required to market our
products, failure to receive these registrations or approvals, or future loss of
previously obtained registrations or approvals could have a material adverse
effect on our business, financial condition and results of operations.

                                       8
<PAGE>
    Even if we receive the necessary regulatory approvals for the GlucoWatch
system, there can be no assurance that unforeseen problems will not occur in
product manufacturing and commercial scale-up or marketing or product
distribution. Any such occurrence could significantly delay the
commercialization of the GlucoWatch system or prevent its market introduction
entirely. Furthermore, even if the GlucoWatch system is successfully developed,
the commercial success of the GlucoWatch system will depend on its acceptance in
the market as well as on our ability to generate enhanced products.

MANUFACTURING; DEPENDENCE ON THIRD-PARTY SUPPLIERS

    Our GlucoWatch system has not yet been manufactured for commercial sale, and
we have no experience manufacturing the volumes that would be necessary for us
to achieve significant commercial sales. To successfully commercialize the
GlucoWatch system, it will have to be manufactured in compliance with regulatory
requirements, in a timely manner and in sufficient quantities while maintaining
product performance, quality and acceptable manufacturing costs. There can be no
assurance that we will be able to establish and maintain reliable, full-scale
manufacturing of the GlucoWatch system at commercially reasonable prices.
Manufacturers often encounter difficulties in scaling up production of new
products, including problems involving product performance, production yields,
quality control and assurance, and shortages of personnel. In addition,
manufacturing facilities will be subject to extensive regulations, including
international quality standards and other regulatory requirements. Difficulties
encountered in manufacturing scale-up or failure by us to implement and maintain
manufacturing facilities in accordance with international quality standards or
other regulatory requirements could result in a delay or termination of
production, which could have a material adverse effect on our business,
financial condition and results of operations.

    In the past, we have experienced these problems in scaling up our
transdermal drug delivery products for commercial launch. There can be no
assurance that similar problems will not be encountered in the future with our
new diagnostic devices. In addition, there can be no assurance that we will be
able to achieve and maintain product performance, quality and reliability if and
when we are able to produce our GlucoWatch system in the quantities required for
commercialization, or that the GlucoWatch system can be assembled and
manufactured at an acceptable cost.

    The GlucoWatch system will be manufactured from components purchased from
outside suppliers, most of which are our single source for such components. In
the event we are unable to obtain these components from our suppliers, we will
be required to obtain components from alternate suppliers. Any interruption in
the supply of GlucoWatch system components could have a material adverse effect
on our business, financial condition and results of operations.

    Currently, our facility complies with ISO 9002, EN 46002, and U.S. Quality
System Regulations standards. We hold a medical Device Manufacturing License
from the California Department of Health Services, Food and Drug Branch. We are
currently establishing our AutoSensor and biographer commercial manufacturing
operations in two existing third-party facilities, which also comply with
applicable regulatory requirements. We cannot, however, assure you that these
facilities will maintain compliance with regulatory requirements.

THIRD-PARTY REIMBURSEMENT

    Successful commercialization of certain of our products may depend in part
on the availability of reimbursement from third-party healthcare payers, such as
private insurance plans and the government. There can be no assurance that such
reimbursement will be available. Third-party payers are increasingly attempting
to contain healthcare costs by limiting both coverage and the level of
reimbursement for new therapeutic and diagnostic products. There can be no
assurance that adequate levels of reimbursement will be available to enable us
to achieve market acceptance of the GlucoWatch system or other new products
under development or to maintain price levels sufficient to realize an
appropriate return on our investment. In certain countries, the period of time
needed to obtain such reimbursement can be lengthy. We may delay the launch of
our products in certain countries until eligibility for reimbursement is
established. This could potentially harm our business, financial condition and
results of operations.

CONVERTIBLE DEBT

    In February 1998, we entered into Note Purchase Agreements with certain
institutional investors to issue and sell approximately $43.0 million of 4%
Senior Subordinated Convertible Notes Due in 2005 ("Notes"). On October 28,
1998, we restructured the Notes. Key provisions in the restructured Notes
included the October 1998 repayment of $18.5 million in principal (reducing the
principal balance from $43.0 million to $24.5 million), a delay in the
convertibility of the majority of the Notes to June 30, 1999 or after,
modification of the conversion prices of the Notes, our ability to redeem at par
at any time all or part of the new principal amount of the Notes, an increase in
the interest rate to 5.5% paid annually on the new principal balance and a
change in the final maturity of the Notes to October 1, 2000.

    The restructured Notes, which totaled $24.5 million, were divided into three
tranches. The first tranche had an original principal amount of $6.0 million and
was fully converted into Common Stock by January 1999 at $3.54 per share. The
second tranche also had an original principal amount of $6.0 million and was
fully converted into Common Stock on June 30, 1999 at $6.89 per share (such
conversion price determined by a market-based formula on February 1, 1999). The
third tranche of the restructured Notes had an original principal amount of
$12.5 million and could not have been converted into Common Stock until July 1,
1999, at a conversion price that would have been determined based on
market-based pricing formulas which contained look-back provisions. Also, under
the terms of the restructured Notes, if we issued a call before July 1, 1999 for
the redemption of the third tranche, the Note Holders would not be entitled to
convert any portion of that tranche. On June 29, 1999, we issued redemption
notices for the entire third tranche and, accordingly, the Note Holders were not
entitled to convert any portion of that tranche. On July 9, 1999, we paid $12.5
million in principal and $0.4 million in accrued interest to redeem the third
tranche. As a result, the remaining unamortized debt issuance costs of $1.1
million were expensed.

    On the date the Notes were restructured (October 28, 1998), the conversion
price for the first tranche was below the quoted market price of our Common
Stock. Consequently, we computed a beneficial conversion feature by comparing
the quoted market price of our Common Stock on that date ($6.06125) to the
conversion price of the first tranche ($3.5375) and then by multiplying the
difference by the number of shares (1.7 million) into which the first tranche
was convertible. The

                                       10
<PAGE>
above computation resulted in a total charge of $4.2 million, which was written
off as interest expense at the date of restructuring.

    In order to help finance the redemption of the third tranche discussed
above, and to provide additional capital, in 1999 we entered into two new
financing arrangements: a Convertible Debenture and Warrant Purchase Agreement
and a Structured Equity Line Flexible Financing Agreement.

    On June 29, 1999, we entered into a Convertible Debenture and Warrant
Purchase Agreement with institutional investors ("Investors") to issue and sell
$14.0 million principal amount of 8.5% Convertible Debentures Due June 29, 2004
("Convertible Debentures"). These Convertible Debentures are convertible into
shares of Common Stock at any time at a conversion price of $12.705 per share.
We received gross proceeds of $14.0 million from the issuance of the Convertible
Debentures and incurred debt issuance costs of $0.5 million. With the mutual
agreement of the Investors and us, or if certain trading volume, pricing and
other conditions are met, we and/or the Investors will have the right to require
the sale to existing Investors of an additional $6.0 million in additional
aggregate principal amount of Convertible Debentures in two separate tranches of
$3.0 million each (each an "Additional Tranche"), provided that the second
Additional Tranche notice date may not be earlier than sixty days after the
first Additional Tranche notice date. The conversion price for each Additional
Tranche will be the average of the closing bid prices for the ten trading days
prior to and including the respective Additional Tranche notice date and the ten
trading days subsequent to the respective Additional Tranche notice date
("Additional Closing Price") multiplied by 110%. On September 29, 1999 we
received $3.0 million in gross proceeds from the issuance of the first
Additional Tranche due September 29, 2004, with a conversion price of $11.8663
(determined by the above market-based formula), and incurred debt issuance costs
of $0.1 million. Neither the June 29, 1999 nor the September 29, 1999
Convertible Debentures contained any beneficial conversion features.

    In conjunction with the issuance of Convertible Debentures in June, 1999,
and the first Additional Tranche in September 1999, we issued to the debenture
holders warrants to purchase approximately 606 thousand shares and 139 thousand
shares of Common Stock, at the exercise price of $13.86 per share and $16.18 per
share, respectively. Each tranche of warrants had a contractual term of
five years from the date of respective grant. At the respective dates of grant,
the fair values ascribed to these warrants were approximately $5.0 million and
$1.1 million, respectively, based on a Black-Scholes valuation model, and were
recorded as debt discount and are being amortized as additional interest expense
over the debt term. We recorded amortization of $0.6 million in 1999. As of
December 31, 1999, the unamortized fair value amounted to $5.5 million. We will
be required to issue warrants if the second Additional Tranche of the
Convertible Debentures is sold. Such warrants will be priced at 150% of the
respective Additional Closing Price. The number of additional warrants to be
issued will be determined by dividing 50% of the respective Additional Tranche
by the respective Additional Closing Price.

    We also issued to the placement agent warrants to purchase 50 thousand
shares of Common Stock at the exercise price of $13.86 per share. At the date of
grant, the fair value ascribed to the warrants was approximately $417 thousand,
based on a Black-Scholes valuation model, and that amount was recorded as
deferred financing cost and is being amortized as additional interest expense
over the debt term. We recorded amortization of $42 thousand in 1999.

                                       11
<PAGE>
    The Convertible Debentures have a stated interest rate of 8.5% and an
effective interest rate of 18.20%. The effective interest rate includes a
non-cash charge of $6.6 million for the amortization of the implicit value of
warrants issued in connection with the Convertible Debentures.

STRUCTURED EQUITY LINE

    On June 30, 1999, we also entered into a Structured Equity Line Flexible
Financing Agreement ("Equity Line") with certain institutional investors
("Investors"). The Equity Line is effective for two years ("Commitment Period")
and allows us, at our sole discretion, to sell Common Stock with a maximum
aggregate issue price of $30.0 million over the Commitment Period. On June 30,
1999, we received net proceeds of approximately $3.8 million, after deducting
the issuance costs, from the sale of approximately 346 thousand shares of Common
Stock (the "Initial Investment"). The number of shares of Common Stock for the
Initial Investment was determined on the basis of the average closing bid price
for the ten trading days prior to June 30, 1999 ("Initial Investment Purchase
Price"). Under the terms of the Equity Line, over a period of eighty
trading days following June 30, 1999 ("Initial Period"), the Investors were
required to deliver purchase notices from time to time for the aggregate amount
of the Initial Investment ($4.0 million) to purchase shares of our Common Stock.
The per-share price for each such purchase notice equaled 98% of the average of
the two lowest daily trade prices during the six trading days immediately prior
to the respective purchase notice. The number of shares originally issued was
subject to an upward adjustment, if required, to match the aggregate number of
shares covered by the $4.0 million of purchase notices. We issued an additional
92 thousand shares to reflect the actual purchase prices on the purchase
notices.

    On September 29, 1999, we issued 361 thousand shares of Common Stock for
$4.0 million ("Additional Investment") pursuant to an amendment to the Equity
Line agreement which allowed for an Additional Investment period of 110 days
("Additional Period"). The terms for this Additional Investment are similar to
those applied to the Initial Investment, and the number of shares was adjusted
upwards at the end of the Additional Period, resulting in the issuance of an
additional 92 thousand shares of Common Stock.

    After the Initial Period and the Additional Period, on a monthly basis
("Investment Period"), we can elect, at our sole discretion, to sell up to $1.5
million ("Company Election") in additional shares of Common Stock. In addition
to the above and upon our approval, the Investors may also elect to purchase an
additional $1.0 million ("Investor Election") of Common Stock in each Investment
Period. In each Investment Period in which we elect to sell additional shares,
the Investors will from time to time issue purchase notices for the aggregate
amount of the Company Election and the Investor Election, if applicable. The
per-share price of Common Stock to be sold for each such purchase notice will
equal 98% of the average of the two daily low trade prices during the six
trading days immediately prior to the respective purchase notice. At the
beginning of each Investment Period, we can set a minimum sales price ("Floor
Price") for our Common Stock. The Investors may require the aggregate dollar
amount of the Company Election and Investor Election for any Investment Period
to be less than requested, based on certain market trading volume guidelines. In
December 1999, we sold 100 thousand shares of Common Stock for $1.5 million
pursuant to the Equity Line. In January 2000, we sold an additional 59 thousand
share of Common Stock for $1.0 million pursuant to the Equity Line.

                                       12
<PAGE>
    In conjunction with the Equity Line, in January 2000 we issued five-year
warrants to the Investors to purchase 95 thousand shares of Common Stock at
$11.51 per share. The price of the warrants will be determined each calendar
year and will equal 120% of the weighted average per-share sales price of all
shares of Common Stock sold pursuant to the Equity Line that year. The number of
shares will equal 1% of the aggregate proceeds received for all shares sold
pursuant to the Equity Line during the year. Warrants to purchase a minimum of
120 thousand shares must be issued under the Equity Line and, if at the end of
the Commitment Period, warrants to purchase less than 120 thousand shares of
Common Stock have been issued, we must issue a warrant to purchase the number of
shares equal to the difference, at a price equal to 120% of the average exercise
price of all warrants previously issued pursuant to the Equity Line.

PATENTS AND PROPRIETARY RIGHTS

    It is our policy to aggressively protect our investments in technology and
marketing by filing patent and trademark applications in the U.S. and key
foreign countries. We also rely on trade secrets, know-how, licensing
opportunities, and collaborative relationships to develop and maintain our
competitive position.

    As of December 1999, and after the sale of substantially all of our drug
delivery business assets, including the intellectual property associated
therewith, we have seven issued U.S. patents and six issued foreign patents,
with approximately sixty additional patent applications pending worldwide. These
patents and applications cover various aspects of analyte monitoring, including
glucose monitoring systems and represent over twenty patent families. As of
December 1999, we have four U.S. trademark registrations, with four U.S.
trademark applications pending or published, and about thirty-nine foreign
trademark registrations, with approximately twenty-one additional foreign
trademark applications pending. Our "GlucoWatch" trademark is registered in the
U.S., the European Community, and additional foreign countries.

    Additionally, our GlucoWatch system incorporates technology licensed
exclusively to us by The Regents of the University of California. The Regents
hold U.S. and foreign patents covering technology for transdermal extraction of
glucose and other analytes.

EMPLOYEES

    As of December 31, 1999, we had eighty-four full-time employees. Of this
total number of employees, forty-six were engaged in research and development,
including process developments; eight in scientific affairs and quality
assurance; twenty-three in general administrative; and seven in operations. None
of our employees is represented by a labor union. We have experienced no work
stoppages and believe our employee relations are good.

    Our success will depend in large part on the continued services of our
scientific, managerial and manufacturing personnel. The loss of a significant
group of key personnel could have a material adverse effect on us. Our success
also depends upon our ability to continue to attract and retain other highly
qualified scientific, managerial and manufacturing personnel. Competition for
such personnel is intense. In this respect, we compete with numerous
pharmaceutical and healthcare companies, as well as universities and nonprofit
research organizations. There can be no assurance that we will continue to be
able to attract and retain sufficient qualified personnel.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER MATTERS

    The market price for shares of our Common Stock has been highly volatile.
Factors such as the results of clinical trials for our products or products of
our competitors, announcements of technological innovations, strategic
relationships, new product introductions by us or our competitors, governmental
regulation, regulatory approvals or delays, and developments relating to our
patent or proprietary rights or those of our competitors, as well as
period-to-period fluctuations in financial results, may have a significant
impact on the market price of the Common Stock. Additionally, in recent years,
the stock market has experienced extreme price and volume fluctuations.

    Our Common Stock trades on the Nasdaq national market tier of the Nasdaq
Stock Market-SM- under the symbol "CYGN." The following table sets forth, for
the periods indicated, the high and low closing sale prices per share of the
Common Stock as reported by the national market.

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

    THIS REPORT CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES RELATING TO THE FUTURE FINANCIAL PERFORMANCE OF CYGNUS, INC.
("CYGNUS," "THE COMPANY," "WE," "OUR," "US" ), AND ACTUAL EVENTS OR RESULTS MAY
DIFFER MATERIALLY. IN EVALUATING SUCH STATEMENTS, STOCKHOLDERS AND INVESTORS
SHOULD SPECIFICALLY CONSIDER THE VARIOUS FACTORS IDENTIFIED UNDER THE CAPTION
"RISK FACTORS" CONTAINED BELOW IN THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATION, AS WELL AS UNDER BUSINESS ABOVE,
WHICH COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE INDICATED BY
SUCH FORWARD-LOOKING STATEMENTS. WE UNDERTAKE NO OBLIGATION TO PUBLICLY RELEASE
THE RESULTS OF ANY REVISIONS TO THESE FORWARD-LOOKING STATEMENTS WHICH MAY BE
MADE TO REFLECT EVENTS OR CIRCUMSTANCES AFTER THE DATE HEREOF OR TO REFLECT THE
OCCURRENCES OF UNANTICIPATED EVENTS.

GENERAL

    We are engaged in the development and manufacture of diagnostic medical
devices, utilizing proprietary technologies to satisfy unmet medical needs cost
effectively. Our current efforts are primarily focused on a frequent, automatic
and non-invasive glucose monitoring device, the GlucoWatch-Registered Trademark-
system, and enhancements thereto. In 1999, we sold substantially all of our drug
delivery business to Ortho-McNeil Pharmaceutical, Inc., and chose to focus on
glucose monitoring systems. The drug delivery business has been accounted for as
a discontinued operation and prior years' financial statements have been
restated to report only continuing operations. For us to remain competitive, we
will need to develop, in-license or acquire new diagnostic products.

    Our results of operations vary significantly from year to year and have
depended on, among other factors, the signing of new product development
agreements and the timing of recognizing payment amounts specified thereunder,
the timing of recognizing license or distribution fees and cost reimbursement
payments made by pharmaceutical licensees, and the demand for our products. The
level of revenues in any given period is not necessarily indicative of expected
revenues for future periods. In 1999, 97% of our revenues were attributable to
one customer. We have incurred net losses each year since our inception and do
not believe we will achieve profitability in 2000. At December 31, 1999, our
accumulated deficit and net capital deficiency were approximately
$178.8 million and $1.2 million, respectively.

                                       17

RESULTS OF OPERATIONS:

    The drug delivery business has been accounted for as a discontinued
operation and prior years' financial statements have been restated to report
only continuing operations. As a result no product revenues, royalty revenues or
costs of products sold have been reflected in our financial statements.

COMPARISON FOR THE YEARS ENDED DECEMBER 31, 1999 AND 1998

    CONTRACT REVENUES for the year ended December 31, 1999 were $2.1 million,
compared to the $0.5 million for the year ended December 31, 1998. Contract
revenues primarily reflect the amortization of previously deferred and
additional milestone payments relating to the GlucoWatch system. The increase in
contract revenue was primarily due to the amortization of an additional
milestone payment received in 1999.

    In 1996, we entered into a collaboration agreement with Yamanouchi
Pharmaceutical Co., Ltd. for the commercialization of the GlucoWatch biographer
in Japan and Korea. Cygnus is eligible to receive milestone payments prior to
commercialization and to receive a percentage of the product's future commercial
success in Japan and Korea.

    In September 1999, we were awarded a six-month Phase I Small Business
Innovative Research Grant for "High Performance Biosensor Electrode Materials"
from the National Institute of Diabetes and Digestive and Kidney Diseases
division of the NIH in the amount of $0.1 million. We are using the funding to
investigate advancements in biosensor materials used for glucose detection and
measurement, potentially to include in future versions of the GlucoWatch system.
Revenue is recognized as reimbursable expenses are incurred.

    Contract revenues, if any, are expected to fluctuate from quarter to quarter
and from year to year, and future contract revenues, if any, cannot be
reasonably predicted. The contributing factors to achieving contract revenues
include, but are not limited to, future successes in finalizing new
collaborative agreements, achievement of milestones under our current contract,
and strategic decisions on self-funding certain projects. We are unable to
predict to what extent the termination of any existing contracts or new
collaborative agreements, if any, will impact overall contract revenues in 2000
and subsequent future periods.

    RESEARCH AND DEVELOPMENT EXPENSES for the year ended December 31, 1999 were
$15.7 million, compared to $25.6 million for the year ended December 31, 1998.
This decrease reflects a reduction in clinical studies and development
expenditures associated with the GlucoWatch system. Research, development and
clinical activities primarily included support and development for the glucose
monitoring program. We anticipate that the development of new products and
technologies, along with additional clinical trials, will result in an increase
in our overall research and development expenses in 2000.

    MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES for the year ended
December 31, 1999 were $4.8 million, compared to $8.8 million for the year ended
December 31, 1998. The decrease was primarily due to reduced compensation and
market research expenses. We expect that marketing, general and administrative
expenses will increase in 2000 as we plan for possible regulatory approval and
commercialization of our GlucoWatch system.

                                       18
<PAGE>
    INTEREST INCOME (EXPENSE), NET OF INTEREST AND OTHER EXPENSE for the year
ended December 31, 1999 was ($3.5) million, compared to ($6.4) million for the
year ended December 31, 1998. The decrease was due primarily to the recording in
1998 of the (i) $4.2 million non-cash costs of the beneficial conversion feature
associated with the October 1998 restructuring of the 4% Senior Subordinated
Convertible Notes and (ii) write-off of the previously deferred debt issuance
cost of $1.0 million, in conjunction with the partial repayment of the Senior
Subordinated Convertible Notes, offset by a net arbitration settlement with
Pharmacia & Upjohn from which Cygnus received $2.7 million.

    INCOME FROM OPERATIONS OF DISCONTINUED SEGMENT for the year ended
December 31, 1999 was $3.0 million, compared to $1.0 million for the year ended
December 31, 1998. The increase was due primarily to a decrease in overall
segment expenses.

    DISCONTINUED OPERATIONS.  On December 15, 1999, we completed the sale of
substantially all the assets of our drug delivery business to Ortho-McNeil
Pharmaceutical, Inc. Total revenues and net income on the discontinued
operations were $12.3 million and $3.0 million, respectively, for the year ended
December 31, 1999. We also recorded a gain of $16.3 million on the disposal of
the segment.

COMPARISON FOR THE YEARS ENDED DECEMBER 31, 1998 AND 1997

    CONTRACT REVENUES for the year ended December 31, 1998 were $0.5 million,
compared to the $2.1 million for the year ended December 31, 1997. Contract
revenues primarily reflected the amortization of previously deferred milestone
payments relating to our GlucoWatch system. The decrease in contract revenue was
primarily attributable to the decrease in amortization of these milestone
payments.

    RESEARCH AND DEVELOPMENT EXPENSES for the year ended December 31, 1998 were
$25.6 million, compared to $16.2 million for the year ended December 31, 1997.
The increase in research and development expenses for the year ended
December 31, 1998 was primarily due to the increased costs associated with the
GlucoWatch biographer and the AutoSensor in the following areas: material,
design and scale-up for development efforts, and material and outside charges
for the accelerated level of clinical activities. Research and development and
clinical activities primarily included support and development for the glucose
monitoring program.

    MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES for the year ended
December 31, 1998 were $8.8 million, compared to $2.2 million for the year ended
December 31, 1997. The increase was primarily due to increased sales and
marketing expenses related to the GlucoWatch system, in particular marketing
research expenses.

    INTEREST INCOME (EXPENSE), NET OF INTEREST AND OTHER EXPENSE for the year
ended December 31, 1998 was ($6.4) million, compared to $1.1 million for the
year ended December 31, 1997. The decrease was due primarily to the
$4.2 million non-cash costs of the beneficial conversion feature associated with
the October 1998 restructuring of the 4% Senior Subordinated Convertible Notes,
the interest expense associated with the subordinated convertible debt, the
amortization of the financing fees related to this debt and the interest related
to the additional long-term debt incurred in the second quarter of 1998.

    INCOME/(LOSS) FROM OPERATIONS OF DISCONTINUED SEGMENT for the year ended
December 31, 1998 was a profit of $1.0 million, compared to a loss of
($35.3) million for the year ended December 31, 1997.

                                       19
<PAGE>
The change was due primarily to a non-recurring arbitration settlement expense
with Sanofi of $39.7 million.

LIQUIDITY AND CAPITAL RESOURCES

    Cash, cash equivalents and investment balances as of December 31, 1999
totaled $38.9 million, representing an increase of $10.1 million from the total
as of December 31, 1998. As of December 31, 1999, we had a negative net worth of
$1.2 million.

    Through December 1999, we have received net proceeds of approximately
$104.5 million from public offerings of our Common Stock.

    Through December 1999, we financed approximately $11.1 million of
manufacturing and research equipment under capital loan and lease arrangements.
Borrowings under those arrangements are secured by specific Cygnus assets.

    We have an outstanding bank loan with Silicon Valley Bank that requires
monthly principal and interest payments through November 2001, in addition to
compliance with various financial covenants. As of December 31, 1999 there was
$5.6 million outstanding under this agreement. Borrowings under this agreement
are secured by specific Cygnus assets.

    In February 1998, we entered into Note Purchase Agreements with
institutional investors to issue and sell approximately $43.0 million of 4%
Senior Subordinated Convertible Notes Due 2005 (the "Notes"). On October 28,
1998, we restructured the Notes. Key provisions in the restructured Notes
include the October 1998 repayment of $18.5 million in principal (reducing the
principal balance from $43.0 million to $24.5 million), a delay in the
convertibility of the majority of the Notes to September 30, 1999, modification
of conversion prices of the Notes, our ability to redeem at par at any time all
or part of the new principal amount of the Notes, an increase in the interest
rate to 5.5% paid annually on the new principal balance and a change in the
final maturity of the Notes to October 1, 2000. Through June 30, 1999,
$6.0 million was converted into Common Stock at a price of $3.54 per share and
$6.0 million was converted into Common Stock at a price of $6.89 per share. The
remaining $12.5 million and accrued interest was redeemed in July 1999.

    In June 1999, we entered into a Convertible Debenture and Warrant Purchase
Agreement with institutional investors to issue and sell up to $20 million
principal amount of 8.5% five-year Convertible Debentures. In June 1999, we
issued $14.0 million principal amount of 8.5% Convertible Debentures Due
June 29, 2004 at par. On September 29, 1999 we issued $3.0 principal amount of
8.5% Convertible Debentures due September 29, 2004 at par.

    On June 30, 1999, we also entered into a Structured Equity Line Flexible
Financing Agreement. The Equity Line is effective for two years and allows us,
at our sole discretion, to sell shares of our Common Stock with a maximum
aggregate sales price of up to $30.0 million. On June 30, 1999 we received
$4.0 million from the sale of a total of 438 thousand shares of Common Stock
under the Equity Line. On September 29, 1999, we received an additional
$4.0 million in exchange for a total of 453 thousand shares of Common Stock
pursuant to the Equity Line agreement. In December 1999, we sold 100 thousand
shares of Common Stock for $1.5 million. In January 2000, we sold an additional
59 thousand shares of Common Stock for $1.0 million pursuant to the Equity Line.
(See Note 9 in the "Notes to Consolidated Financial Statements" in this report.)

                                       20
<PAGE>
    In addition to the cash received from the offerings, issuance of Notes,
Equity Line, equipment lease and short-term working capital financing, we have
financed our operations primarily through revenues and interest income.

    Net cash used in operating activities for the year ended December 31, 1999
was $17.9 million, compared with net cash used of $42.5 million for year ended
December 31, 1998. Cash used in operating activities during the year ended
December 31, 1999 was primarily due to the net loss from continuing operations
of $22.2 million, and decreases in deferred compensation and other liabilities
of $4.4 million, offset by a decrease in deferred compensation, prepaid expenses
and other assets of $4.4 million and accounts receivable of $0.8 million;
depreciation and amortization of 1.9 million; and debt issuance and financing
costs and debt discount of $1.7 million. Cash used in operating activities
during the year ended December 31, 1998 was primarily due to our net loss of
$39.4 million and a $14.0 million cash payment made in January 1998 to Sanofi
under the terms of the arbitration settlement; offset by the non-cash beneficial
conversion costs of $4.2 million associated with the October 1998 restructuring
of the Notes, an increase in accounts payable and other accrued liabilities of
$2.3 million, depreciation and amortization of $1.9 million, and amortization of
debt issuance and financing costs and debt discount of $1.6 million.

    The current level of cash used in operating activities is not necessarily
indicative of the level of future cash usage. We expect an increase in operating
cash usage for 2000.

    Net cash provided by investing activities of $24.8 million for the year
ended December 31, 1999 resulted primarily from the receipt of $20.0 million
from the sale of the drug delivery business, net sales of investments of
$8.3 million, offset by capital expenditures of $2.7 million and a contract
termination fee of $0.8 million in conjunction with disposal of the drug
delivery segment. Net cash used in investing activities of $7.6 million for the
year ended December 31, 1998 resulted primarily from net purchases of
investments of $4.2 million and capital expenditures of $3.4 million.

    Net cash provided by financing activities of $11.6 million for the year
ended December 31, 1999 includes, as mentioned above, net proceeds of $16.4
million and $9.2 million from the June 1999 and September 1999 issuance of 8.5%
Convertible Debentures and from the sale of Common Stock under the Equity Line,
respectively, and additional stock proceeds of $5.7 million, offset by the July
1999 redemption of Senior Subordinated Convertible Notes of $12.5 million, and
long-term debt and capital lease repayments of $5.3 million and $1.9 million,
respectively. Net cash provided by financing activities of $39.7 million for the
year ended December 31, 1998 includes, as mentioned above, net proceeds of $40.4
million and $13.3 million from our February 1998 issuance of Senior Subordinated
Convertible Notes and from a direct public offering of our Common Stock,
respectively; additional stock proceeds of $0.9 million and $6.1 million from
the issuance of long-term debt, offset by a subordinated debt principal
repayment of $18.5 million, and long-term debt and capital lease repayments of
$2.0 million and $0.5 million, respectively.

    Our long-term capital expenditure requirements will depend upon numerous
factors, including the progress of our research and development programs, the
time required to obtain regulatory approvals, the resources that we devote to
the development of self-funded products, proprietary manufacturing methods and
advanced technologies, our ability to obtain additional licensing arrangements
and to manufacture products under those arrangements, the additional
expenditures to support the manufacture of new products, if and when approved,
and possible acquisitions of

                                       21
<PAGE>
products, technologies and companies. As we evaluate the progress of our
development projects, in particular the GlucoWatch system and our enhanced
glucose monitoring products in development, our commercialization plans and the
lead time to set up manufacturing capabilities, we may commence long-term
planning for another manufacturing site. Nevertheless, we believe that such
long-term planning will not result in any material impact on cash flows and
liquidity for the next twelve months.

    Based upon current expectations for operating losses and projected
short-term capital expenditures, we believe that existing unrestricted cash,
cash equivalents and investments of $38.9 million as of December 31, 1999, when
coupled with cash from revenues and other funding, such as from potential
product funding collaborations or from public financings (including debt or
equity financings) and earnings from investments, will be sufficient to meet our
operating expenses, debt servicing and repayments and capital expenditure
requirements at least through December 31, 2000. However, there can be no
assurance that we will not require additional financing, depending upon future
business strategies, manufacturing and commercialization efforts, results of
clinical trials and management decisions to accelerate certain research and
development programs and other factors.

    INCOME TAXES.  We recorded a $0.2 million income tax provision consisting
entirely of foreign withholding taxes for the year ended December 31, 1999. As
of December 31, 1999, we had federal net operating loss and research and
development tax credit carryforwards of approximately $152.6 million and $3.7
million, respectively. We had state net operating loss and tax credit
carryforwards of approximately $36.5 million and $3.1 million, respectively.
These carryforwards will expire at various dates beginning in 2000. Because of
the "change in ownership" provisions of the Internal Revenue Code, a substantial
portion of our net operating loss and tax credit carryforwards may be subject to
annual limitations. The annual limitations may result in the expiration of the
net operating losses and tax credits before utilization.

IMPACT OF YEAR 2000

    In prior years, we discussed the nature and progress of our plans to become
Year 2000 ready. In late 1999, we completed our remediation and testing of
systems. As a result of those planning and implementation efforts, we
experienced no significant disruptions in mission critical information
technology and non-information technology systems and believe these systems
successfully responded to the Year 2000 date change. We expensed approximately
$150 thousand during 1999 in connection with remediating our systems. We are not
aware of any material problems resulting from Year 2000 issues, either with our
products, our internal systems, or the products and services of third parties.
We will continue to monitor our mission critical computer applications and those
of our suppliers and vendors throughout the year 2000 to ensure that any latent
Year 2000 matters that may arise are addressed promptly.

RISK FACTORS

    We wish to caution stockholders and investors that the following important
factors, among others, in some cases have affected, and in the future could
affect, our actual results and could cause our actual consolidated results for
1999 and beyond to differ materially from those expressed in any forward-looking
statements made by or on behalf of Cygnus. The statements under this caption are
intended to serve as cautionary statements within the meaning of the Private
Securities Litigation

                                       22
<PAGE>
Reform Act of 1995. The following information is not intended to limit in any
way the characterization of other statements or information under other captions
as cautionary statements for such purpose.

OUR PRODUCT PIPELINE IS SEVERELY LIMITED.

    With the sale of the majority of the drug delivery business assets to
Ortho-McNeil Pharmaceutical, Inc., and the termination of the remaining drug
delivery projects, we are now exclusively focused on diagnostic medical devices,
initially on a line of frequent, automatic and non-invasive glucose monitoring
devices. There is an inherent risk in not having a broad base of products in
development and we cannot assure you that we will be successful with this narrow
line of products.

WE MAY NOT RECEIVE FDA APPROVAL ON OUR PRODUCTS.

    Although the FDA's Clinical Chemistry and Toxicology Devices Panel of the
Medical Devices Advisory Committee has recommended the GlucoWatch biographer for
approval for sale with three conditions, there can be no assurance that we can
meet these conditions or, if we can, that the recommendation of the Advisory
Committee will convince the FDA to approve the product. Additionally, there can
be no assurance that the FDA will approve the GlucoWatch biographer on the same
terms, if at all. Furthermore, as we seek regulatory approval for enhancements
and possible manufacturing changes through the PMA supplement process, there can
be assurances that such supplements will be approved or that one or more new
PMAs will not need to be filed.

    Even if we receive the necessary regulatory approvals for the GlucoWatch
system, there can be no assurance that unforeseen problems will not occur in
product manufacturing and commercial scale-up or marketing or product
distribution. Any such occurrence could significantly delay the
commercialization of the GlucoWatch system or prevent its market introduction
entirely. Furthermore, even if the GlucoWatch system is successfully developed,
the commercial success of the GlucoWatch system will depend on its acceptance in
the market.

WE HAVE LIMITED MARKETING, DISTRIBUTION, MANUFACTURING AND SALES EXPERIENCE.

    We have limited experience marketing, distributing, manufacturing or selling
medical device products. To successfully market, distribute, manufacture and
sell the GlucoWatch system or our other glucose monitoring products under
development, we must either develop a more extensive marketing, distributing,
manufacturing and sales force or enter into arrangements with third parties to
market, distribute, manufacture and sell our products. We cannot assure you that
we will be able to successfully develop a more extensive marketing,
distributing, manufacturing and sales force or that we will enter into
acceptable marketing, distributing, manufacturing and sales agreements with
third parties. If we maintain our own marketing, distributing, manufacturing and
sales capabilities, we will compete with other companies that have experienced
and well-funded marketing, distributing, manufacturing and sales operations. If
we enter into a marketing arrangement with a third party, any revenues we
receive will depend on the third party, and we will likely have to pay a sales
commission or similar amount. We may be unable to successfully commercialize our
products.

                                       23
<PAGE>
WE CANNOT PREDICT THE MARKET ACCEPTANCE OF OUR PRODUCTS.

    We are focusing our efforts predominantly on a line of frequent, automatic,
and non-invasive glucose monitoring devices. No one can predict market
acceptance or penetration of such products, given that they are entirely
different from any glucose diagnostic product currently on the market. There is
a risk in introducing a very new type of product in a market of established
finger stick glucose monitors, and we cannot assure you that our products will
be accepted or to what degree. Additionally, some of our competitors have
announced, and others may be developing, new, frequent, automatic, and
non-invasive (or minimally invasive, semi-invasive or less-invasive) glucose
monitoring devices. We cannot predict what impact introduction of competing
products will have on our market sales.

WE DEPEND ON PROPRIETARY TECHNOLOGY.

    Our success depends in large part on our ability to obtain patent protection
for our products, preserve our trade secrets and operate without infringing upon
the proprietary rights of others, both in the U.S. and abroad. Since currently
patent applications in the U.S. are maintained in secrecy until issuance, and
publication of discoveries in the scientific or patent literature tends to lag
behind actual discovery by several months, we cannot be certain that we were the
first to file our patent applications or that we will not infringe upon
third-party patents. We cannot assure you that any patents will be issued or
upheld with respect to any of our patent applications or that any patents will
provide competitive advantages for our products or will not be challenged or
circumvented by our competitors. We also rely on trade secrets and proprietary
know-how that we seek to protect, in part, by confidentiality agreements with
our licensees, employees and consultants. We cannot assure you that these
agreements will not be breached, that we would have adequate remedies for any
breach or that our trade secrets will not otherwise become known or be
independently developed by our competitors. Any litigation, in the U.S. or
abroad, as well as foreign opposition and/or domestic interference proceedings,
could result in substantial expense to us and significant diversion of effort by
our technical and management personnel. We may resort to litigation to enforce
our patents or protect trade secrets or know-how, as well as to defend against
infringement charges. A negative determination in such proceedings could subject
us to significant liabilities or require us to seek licenses from third parties.
Although patent and intellectual property disputes in the pharmaceutical product
area have often been settled through licensing or similar arrangements, costs
associated with such arrangements may be substantial and could include ongoing
royalties. Furthermore, we cannot assure you that necessary licenses would be
available to us on satisfactory terms, if at all. Accordingly, an adverse
determination in a judicial or administrative proceeding or failure to obtain
necessary licenses could prevent us from manufacturing and selling certain of
our products, and could materially adversely affect us.

WE FACE INTENSE COMPETITION.

    The medical device industry in general, and the market in which we expect to
offer the GlucoWatch system in particular, is intensely competitive. Even if we
successfully develop the GlucoWatch system, we will compete with other providers
of personal glucose monitors. A number of our competitors are currently
marketing traditional glucose monitors. These monitors are widely

                                       24
<PAGE>
accepted in the healthcare industry and have long histories of accuracy and
effective use. Furthermore, a number of companies have announced that they are
developing products that permit less painful or painless, as well as continual
or continuous, glucose monitoring. Accordingly, we expect competition to
increase. Many of our competitors have substantially greater resources than we
do and have greater name recognition and lengthier operating histories in the
healthcare industry. We cannot assure you that we will be able to compete
effectively against our competitors. Additionally, we cannot assure you that the
GlucoWatch system or our other enhanced products under development will replace
any currently used devices or systems. Furthermore, we cannot assure you that
our competitors will not succeed in developing, even before we develop and
commercialize the GlucoWatch system or our other enhanced products under
development, devices and technologies that permit more-efficient and
less-expensive glucose monitoring devices. Pharmaceutical or other healthcare
companies may also develop therapeutic drugs, treatments or other products that
will substantially reduce the prevalence of diabetes or otherwise render our
products obsolete.

THIRD PARTIES MAY NOT REIMBURSE PATIENTS, HOSPITALS AND PHYSICIANS FOR THE COSTS
OF MEDICAL DEVICES.

    Successful commercialization of certain of our products may depend in part
on the availability of reimbursement from third-party healthcare payers, such as
private insurance plans and the government. There can be no assurance that such
reimbursement will be available. Third-party payers are increasingly attempting
to contain healthcare costs by limiting both coverage and the level of
reimbursement for new therapeutic and diagnostic products. There can be no
assurance that adequate levels of reimbursement will be available to enable us
to achieve market acceptance of the GlucoWatch system or other new products
under development or to maintain price levels sufficient to realize an
appropriate return on our investment. In certain international countries, the
period of time needed to obtain such reimbursement can be lengthy. We may delay
the launch of our products in certain countries until eligibility for
reimbursement is established. This could potentially harm our business,
financial condition and results of operations.

WE HAVE INCURRED SUBSTANTIAL LOSSES, HAVE A HISTORY OF OPERATING LOSSES, HAVE AN
ACCUMULATED DEFICIT AND EXPECT CONTINUED OPERATING LOSSES.

    We reported a net loss from continuing operations of $22.2 million for the
year ended December 31, 1999 and have experienced annual operating losses since
our inception. We expect to continue to incur operating losses at least until we
have significant sales, if we ever do, of the GlucoWatch system. We cannot
assure you that we will generate significant revenues or achieve profitability.
We do not have experience in manufacturing, marketing or selling our medical
device products. Our future development efforts may not result in commercially
viable products. We may fail in our efforts to introduce our products or to
obtain required regulatory clearances. Our products may never gain market
acceptance, and we may never generate revenues or achieve profitability. Our
revenues to date have been derived primarily from product development and
licensing fees related to our products under development, and manufacturing and
royalty revenues from our discontinued operations, including
Nicotrol-Registered Trademark- (Pharmacia AB, Stockholm, Sweden) nicotine patch
and the Fempatch-Registered Trademark- (Warner-Lambert Co., Morris Plains, New
Jersey) system. As a result of the sale of our drug delivery business, we will
no longer receive manufacturing revenue or royalty payments from the Nicotrol
patch or the Fempatch system. If we obtain regulatory approvals, we expect that
a

                                       25
<PAGE>
substantial portion of our future revenues will be derived from sales of the
GlucoWatch system and other diagnostic products currently under development.

WE ARE HIGHLY LEVERAGED AND MAY BE UNABLE TO SERVICE OUR DEBT.

    As of December 31, 1999, we had indebtedness of approximately
$47.0 million. The degree to which we are leveraged could materially adversely
affect our ability to obtain financing for working capital, acquisitions or
other purposes and could make us more vulnerable to industry downturns and
competitive pressures. Our ability to meet our debt service obligations depends
upon our future performance, which will depend upon financial, business and
other factors, many of which are beyond our control. Although we believe our
cash flows will be adequate to meet our interest payments, we cannot assure you
that we will continue to generate cash flows in the future sufficient to cover
our fixed charges or to permit us to satisfy any redemption obligations pursuant
to our indebtedness. If we cannot generate cash flows in the future sufficient
to cover our fixed charges or to permit us to satisfy any redemption obligations
pursuant to our indebtedness, and we cannot borrow sufficient funds either under
our credit facilities or from other sources, we may need to refinance all or a
portion of our existing debt, to sell all or a portion of our assets, or to sell
equity securities. There is no assurance that we could successfully refinance,
sell our assets or sell equity securities, or, if we could, we cannot give any
assurance as to the amount of proceeds we could realize. In the event of
insolvency, bankruptcy, liquidation, reorganization, dissolution or winding-up
of our business or upon default or acceleration relating to our debt
obligations, our assets will first be available to pay the amounts due under our
debt obligations. Holders of Common Stock would only receive the assets
remaining, if any, after payment of all indebtedness and Preferred Stock.

WE MAY NEED ADDITIONAL FINANCING AND IT MAY NOT BE AVAILABLE.

    In order to continue to develop our diagnostic products, we will require
substantial resources to conduct research and development and clinical trials
necessary to bring our products to market and to establish production and
marketing capabilities. We may seek additional funding through public or private
financings, including debt or equity financings. We may also seek other
arrangements, including collaborative arrangements. Any additional equity
financings may dilute the holdings of current stockholders. Debt financing, if
available, may restrict our ability to issue dividends in the future and take
other actions. We may not be able to obtain adequate funds when we need them
from financial markets or arrangements with corporate partners or other sources.
Even if funds are available, they may not be on acceptable terms. If we cannot
obtain sufficient additional funds, we may have to delay, scale back or
eliminate some or all of our research and product development programs or
license or sell products or technologies that we would otherwise seek to develop
ourselves. We believe that our existing cash, cash equivalents and investments,
plus cash from revenues, other fundings such as potential product funding
collaborations or financings, and earnings from investments, will suffice to
meet our operating expenses, debt servicing and repayments and capital
expenditure requirements at least through the end of the year 2000. The amounts
and timing of future expenditures will depend on progress of ongoing research
and development, results of clinical trials, rates at which operating losses are
incurred, executing possible development and licensing agreements with corporate
partners, developing our products, manufacturing scale-up for the GlucoWatch
system, the FDA regulatory process, and several other factors, many of which are
beyond our control.

                                       26
<PAGE>
WE DEPEND ON LICENSEES, DISTRIBUTORS AND COLLABORATIVE ARRANGEMENTS.

    Our strategy to develop, clinically test, obtain regulatory approval for,
manufacture and commercialize our products depends, in large part, upon our
ability to selectively enter into and maintain collaborative arrangements with
third-party partners, distributors, licensees, and other such parties. If we
commercialize our GlucoWatch system, we will depend upon Yamanouchi
Pharmaceutical Co., Ltd. to market and distribute the GlucoWatch system in Japan
and Korea. We do not have any marketing or distribution agreements for the
GlucoWatch system other than the Yamanouchi collaboration. One of our priorities
is to establish an alliance or alliances for the commercialization of the
GlucoWatch system in North America and Europe. The purpose of such an alliance
or alliances is for us to secure certain commercialization functions, such as
distribution, sales and customer service. We are in discussions with several
companies regarding this objective. Some of the companies are international in
scope and would provide the requisite commercialization functions worldwide.
Other companies focus on certain geographies and/or certain commercialization
functions. The potential signing of a worldwide commercialization agreement may
or may not coincide with the launch of our GlucoWatch system, assuming we
receive FDA approval. We are evaluating out-sourced capabilities for a U.S.
launch without a worldwide commercialization alliance. There can be no assurance
that we will be able to enter into a commercialization alliance or alliances or
that we will be able to out-source certain commercialization capabilities for
launch without a worldwide commercialization alliance in place. We cannot assure
you that such third parties will not, for competitive reasons, support, directly
or indirectly, a company or product that competes with one of our products.
Furthermore, any dispute between us and such a third party might require us to
initiate or defend against expensive litigation or arbitration proceedings. If
one of our partners, distributors or licensees terminates an arrangement, cannot
fund or otherwise satisfy its obligations under its arrangements, or
significantly disputes or breaches a contractual commitment, then we would
likely be required to seek an alternative partner, distributor, or licensee. We
cannot assure you that we would be able to reach agreement with a replacement
third party. If we were unable to find a replacement third party, we might not
be able to perform or fund the activities of the current partner, distributor or
licensee. Even if we were able to perform and fund these activities, our capital
requirements would increase substantially. Additionally, we may choose to
self-fund certain research and development projects in order to exploit our
technologies. If these activities result in a commercial product, they will help
our long-term operating results but will negatively affect our short-term
operating results. Furthermore, as discussed above, we have limited marketing,
manufacturing, distribution and sales experience.

WE MAY BE SUBJECT TO PRODUCT LIABILITY CLAIMS.

    The design, development, manufacture and use of our medical products involve
an inherent risk of product liability claims and associated adverse publicity.
Producers of medical products may face substantial liability for damages in the
event of product failure or allegations that the product caused harm. We
currently maintain product liability insurance, but it is expensive and
difficult to obtain and may not be available in the future on acceptable terms.
We cannot assure you that we will not be subject to product liability claims,
that our current insurance would cover any claims, or that adequate insurance
will continue to be available on acceptable terms in the future. In the event we
are held liable for damages in excess of the limits of our insurance coverage,
or if any claim or

                                       27
<PAGE>
product recall creates significant adverse publicity, our business, financial
condition and results of operations could be materially adversely affected.

WE MAY NOT BE ABLE TO RETAIN OR HIRE KEY PERSONNEL.

    Our ability to operate successfully and manage our potential future growth
significantly depends upon retaining key scientific, technical, managerial and
financial personnel, and attracting and retaining additional highly qualified
scientific, technical, managerial and financial personnel. We face intense
competition for qualified personnel in these areas, and we cannot assure you
that we will be able to attract and retain qualified personnel. The loss of key
personnel or our inability to hire and retain additional qualified personnel in
the future could adversely affect our business, financial condition and
operating results.

OUR CERTIFICATE OF INCORPORATION AND BYLAWS HAVE ANTI-TAKEOVER PROVISIONS.

    Our Restated Certificate of Incorporation and Bylaws contain several
provisions that may make the acquisition of control of Cygnus more difficult or
expensive. The Certificate of Incorporation and Bylaws, among other things:
(i) provide that directors may be removed only for cause and only upon the
affirmative vote of the holders of at least a majority of the outstanding shares
of voting stock entitled to vote for such directors, (ii) permit the remaining
directors (but not the stockholders, unless the directors so resolve) to fill
vacancies and newly created directorships on the Board, (iii) eliminate the
ability of stockholders to act by written consent and (iv) require the vote of
stockholders holding at least 66 2/3% of the outstanding shares of voting stock
to amend, alter or repeal the Bylaws and certain provisions of the Restated
Certificate of Incorporation, including the provisions described in (i) through
(iv).

    Such provisions may make the removal of incumbent directors more difficult
and time-consuming and may have the effect of discouraging a tender offer or
other takeover attempt not previously approved by the Board of Directors. Under
the Restated Certificate of Incorporation, the Board of Directors also has the
authority to issue shares of Preferred Stock in one or more series and to fix
the powers, preferences and rights of any such series without stockholder
approval. The Board of Directors could, therefore, issue, without stockholder
approval, Preferred Stock with voting and other rights that could adversely
affect the voting power of the holders of Common Stock and could make it more
difficult for a third party to gain control of Cygnus. In addition, we have
adopted a Stockholder Rights Plan which, under certain circumstances, would
significantly dilute the equity interest of persons seeking to acquire control
over us without the prior approval of the Board of Directors.

OUR STOCK PRICE IS VOLATILE.

    The trading price of our Common Stock substantially fluctuates in response
to factors such as, but not limited to: announcements by us or our competitors
of results of regulatory approval filings or clinical trials or testing,
developments or disputes governing proprietary rights, technological innovations
or new commercial products, government regulatory action, and general conditions
in the medical technology industry, changes in securities analysts'
recommendations, or other events or factors, many of which are beyond our
control. In addition, the stock market in general has experienced extreme price
and volume fluctuations in recent years that have particularly affected the

                                       28
<PAGE>
market prices of many medical technology companies, unrelated to the operating
performance of these companies. Fluctuations or decreases in the trading price
of our Common Stock may adversely affect the market for our Common Stock. In the
past, following periods of volatility in the market price for a company's
securities, securities class action litigation often has been instituted. Such
litigation could result in substantial costs and a diversion of management
attention and resources, which could have a material adverse effect on our
business, financial condition and operating results.

WE DO NOT PAY DIVIDENDS.

    We have never declared or paid cash dividends on our Common Stock. Our
current bank term loan precludes us from paying dividends to stockholders. We
currently intend to retain any earnings for use in our business and therefore do
not anticipate paying any dividends in the future.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

    Our exposure to market risk for changes in interest rates relates primarily
to our investment portfolio and long-term debt obligations. We do not use
derivative financial instruments in our investment portfolio. We place our
investments with high credit quality issuers and, by policy, limit the amount of
credit exposure to any one issuer. As stated in our policy, we are averse to
principal loss and ensure the safety and preservation of our invested funds by
limiting default risk, market risk and reinvestment risk.

    We mitigate default risk by investing in only the highest credit quality
securities. The portfolio includes only marketable securities with active
secondary or resale markets to ensure portfolio liquidity.

    We have no cash flow exposure due to rate changes for our $17.0 million
Convertible Debentures, our $0.7 million equipment loans, and our $6.0 million
convertible promissory note related to the Sanofi arbitration settlement, which
all have fixed rates. We also have no cash flow exposure due to the rate change
for certain long-term portions of our Sanofi arbitration obligations, as such
obligations are not interest-bearing. We do have cash flow exposure on our $5.6
million bank term loan due to its variable interest rate (prime plus 1.0%). We
primarily enter into debt obligations to support general corporate purposes,
including capital expenditures and working capital needs.

    Because we do not have any assets or liabilities in foreign currencies, we
have no risk from exchange rate changes.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Cygnus, Inc.

    We have audited the accompanying consolidated balance sheets of Cygnus, Inc.
as of December 31, 1999 and 1998, and the related consolidated statements of
operations, stockholders' equity (net capital deficiency) and cash flows for
each of the three years in the period ended December 31, 1999. These financial
statements are the responsibility of Cygnus' management. Our responsibility is
to express an opinion on these financial statements based on our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Cygnus, Inc. at
December 31, 1999 and 1998, and the consolidated 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                      FOR THE YEAR ENDED DECEMBER 31, 1999

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

NOTE 1: BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

    Cygnus was incorporated in California in 1985 and was merged into a Delaware
corporation in September 1995. We are engaged in the development and manufacture
of diagnostic systems, utilizing proprietary technologies to satisfy unmet
medical needs cost effectively. Our current efforts are primarily focused on a
frequent, automatic and non-invasive glucose monitoring device, the GlucoWatch
biographer, and enhancements thereto.

CONSOLIDATION

    The consolidated financial statements include the accounts of Cygnus and its
wholly-owned subsidiaries after elimination of all material inter-company
balances and transactions. Cygnus' subsidiaries were inactive in 1999, 1998 and
1997, and were dissolved effective February 21, 2000.

USE OF ESTIMATES

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

FINANCIAL PRESENTATION

    Certain prior-year amounts have been reclassified to conform to the current
year's presentation.

DISCONTINUED OPERATIONS

    On December 15, 1999, we completed the sale of substantially all of our drug
delivery business segment assets to Ortho-McNeil, except for certain assets with
a net book value of $505 thousand of which assets with a net book value of $205
thousand were written off prior to year end.

    We have restated our consolidated statements of operations for the years
ended December 31, 1998 and 1997 to reflect the results of the drug delivery
business as a discontinued operation, in accordance with Accounting Principles
Board Opinion No. 30 (APB 30).

REVENUE RECOGNITION

    Our contract revenues include up-front and interim milestone payments from
development contracts. The amortization of the initial fees and interim
milestone payments is based on the total person hours expended to date by
project, as compared to the estimated total project person hours

                                      F-8

                                  CYGNUS, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      FOR THE YEAR ENDED DECEMBER 31, 1999

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

required, a manner similar to the percentage of completion methodology. Due the
nature of the projects we have undertaken, revenue recognized using our current
policy approximates the revenue that would be recognized using a straight-line
basis. However, contract revenues are not always aligned with the timing of
related expenses. To date, research and development expenses generally have
exceeded contract revenues in any particular period. Deferred revenue includes
the portion of up-front and interim milestone payments received on research,
development and distribution agreements which have been deferred and will be
recognized over the related development period in relation to efforts expended
under the agreement.

CUSTOMER CONCENTRATION

    One customer provided 97% of the 1999 contract revenues. In 1998 this
customer provided 40% of our contract revenues and in 1997 this customer
provided 69% of our contract revenues. Another customer provided zero percent
(0%) of our 1999 contract revenues, 60% of our 1998 contract revenues, and 31%
of our 1997 contract revenues. No other customer provided more than 10% of
contract revenues during the three years ended December 31, 1999.

RESEARCH AND DEVELOPMENT

    Research and development expenses are expensed as incurred.

INVENTORIES

    The December 31, 1998 net inventory consisted primarily of raw materials and
was stated at the lower of cost (first-in, first-out method) or market, after
appropriate consideration was given to obsolescence and inventory in excess of
anticipated future demand.

EQUIPMENT AND IMPROVEMENTS

    Equipment and improvements are recorded at the lower of cost or net
realizable value. Depreciation of equipment is computed on a straight-line basis
over the estimated useful lives of eighteen months to sixty months. Leasehold
improvements and assets recorded under capital leases are amortized using the
straight-line method over the shorter of the estimated useful life of the assets
or the term of the leases. No depreciation charge is computed on assets under
construction.

ACCOUNTING FOR IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE
  DISPOSED OF

    The Financial Accounting Standards Board Statement of Financial Accounting
Standards, No. 121 (FAS 121), "Accounting for the Impairment of Long-lived
Assets and for Long-lived Assets to be Disposed Of," prescribes the accounting
for the impairment of long-lived assets, such as property, plant, equipment, and
intangible assets, as well as the accounting for long-lived assets that are held

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      FOR THE YEAR ENDED DECEMBER 31, 1999

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

for disposal. We review property, plant, equipment, and other long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability is measured
by comparison of its carrying amount to the future net cash flows the assets are
expected to generate. If such assets are considered to be impaired, the
impairment is recognized and is measured as the amount by which the carrying
amount of the asset exceeds the present value of the future net cash flows. In
December 1999, as part of the disposal of the drug delivery business segment, we
recorded a charge of $205 thousand. No charge was incurred during 1998. During
1997, we recorded a charge of $1.3 million relating to the write-off of certain
leasehold improvements resulting from the decision to coordinate research and
development facilities into existing space. This amount was included in research
and development expenses in the consolidated statement of operations for 1997.

DEFERRED COMPENSATION

    In 1995, we adopted a non-qualified deferred compensation plan. The plan was
intended to be unfunded and was maintained primarily for the purpose of
providing deferred compensation for a select group of management. As of
December 31, 1999 and 1998, other long-term assets and other long-term
liabilities related to the plan, which included both contributions and net
investment earnings, amounted to $0.0 million and $4.3 million, respectively.
These investments were directed by the participants. In January 1999, we
terminated the plan and the plan assets were distributed to participants in the
first quarter of 1999.

NET LOSS PER SHARE

    Basic and diluted net loss per share is computed using the weighted average
number of shares of Common Stock outstanding. Shares issuable from stock
options, warrants and Convertible Debentures outstanding are excluded from the
diluted-earnings-per-share computation, as their effect is anti-dilutive.

ACCOUNTING FOR STOCK-BASED COMPENSATION

    Under Statement of Financial Accounting Standard No. 123, "Accounting for
Stock-Based Compensation"(FAS 123), stock-based compensation expense to
employees is measured using either the intrinsic-value method as prescribed by
Accounting Principle Board Opinion No. 25, "Accounting for Stock Issued to
Employees" (APB 25), or the fair-value method described in FAS 123. We have
elected to follow APB 25 and related interpretations in accounting for our
employee stock options and disclose only the pro forma impact of the fair value
method on net income and earnings per share. (See Note 4, "Stockholders'
Equity.")

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

NEW ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standard No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (FAS 133). FAS 133 requires all derivative
instruments to be recorded on the balance sheet at fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designed as part of a
hedge transaction, and, if so, the type of hedge transaction. In June 1999, the
FASB issued FAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of FASB Statement No. 133" (FAS
137), which amends FAS 133 to be effective for all fiscal years beginning after
June 15, 2000 (or January 1, 2001 for Cygnus). We do not currently expect that
adoption of FAS 137 will have a material impact on our financial position or
results of operations.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    We consider all highly liquid investments with a maturity from the date of
purchase of three months or less to be cash equivalents. We invest our excess
cash in high credit quality, highly liquid instruments. These investments have
included Treasury Notes, Federal Agency Securities, Auction Rate Certificates,
Auction Rate Preferred Stock, and Commercial Paper.

    We consider all short-term investments as available-for-sale. As such,
short-term investments are carried at estimated fair value with related
unrealized gains and losses included in stockholders' net capital deficiency.
Realized gains and losses and declines in value judged to be
other-than-temporary on available-for-sale securities are included in investment
income. The cost of securities sold is based on the specific identification
method. Interest and dividends on securities classified as available-for-sale
are included in investment income.

DEFERRED FINANCING COSTS

    Deferred financing costs relate to costs incurred in connection with debt
financing that are amortized over the term of the related debt.

NOTE 3: CREDIT LINES AND LONG-TERM DEBT

    In 1998, we consolidated and amended our working capital bank loans. The new
loan will be repaid through November 2001. As of December 31, 1999, there was
$5.6 million outstanding under this agreement. The line bears interest at one
percentage point above the prime rate (9.50% in total as of December 31, 1999).
In June 1997, we entered into a loan agreement for $1.3 million to finance
additional capital equipment. This line bears interest at a fixed rate of 9.39%
per year. Borrowings under this agreement are secured by specific Cygnus assets.
This loan is being repaid monthly through June 2000. As of December 31, 1999,
there was $0.3 million outstanding. In the second quarter of 1998, we entered
into a new loan agreement for $1.4 million to finance additional capital
equipment. This line bears interest at a fixed rate of 8.87% per year.
Borrowings under this agreement are also secured by specific Cygnus assets and
are being repaid monthly through July 2001. As of December 31, 1999, there was
$0.4 million outstanding. All loan agreements are subject to certain financial
covenants, including minimum cash balances and tangible net worth. If certain of
these covenants are not met, the lenders may require collateral of the amounts
outstanding. In the event of default, the lenders may, at their option, exercise
their rights to remedies specified in the loan agreements, which include, among
other things, the acceleration of amounts due under the agreements. As of
December 31, 1999, we were in compliance with all these covenants.

    In December 1999, we repaid all our lease liabilities and, consequently, at
December 31, 1999 we did not have any assets under capital lease. The future
aggregate principal payments of long-term debt, including equipment financing
lines, are as follows:

    The fair market value of the long-term debt approximates its carrying value
of $6,331.

    We lease our facilities under non-cancelable operating leases expiring in
2003 for three of our four buildings. The terms of the leases provide for rental
payments on a graduated scale. We are recognizing rent expense on a
straight-line method over the lease periods and therefore have accrued for the
rent expense incurred but not paid. Additionally, we lease an off-site warehouse
with a three-year lease term ending in October 2001.

NOTE 4: STOCKHOLDERS' EQUITY

PREFERRED SHARE PURCHASE RIGHTS PLAN

    Pursuant to our Stockholder Rights Plan, the Board of Directors declared a
dividend distribution of one Preferred Share Purchase Right ("Right") for each
outstanding share of Common Stock, issuable on October 18, 1993 to stockholders
of record on that date. These Rights will remain outstanding until
September 21, 2003.

WARRANTS

    Currently, we account for all warrants issued in connection with services
rendered on the basis of the fair value of the warrants. We estimate the fair
value of such instruments by running a Black-Scholes model, and the fair value
thus computed is then recognized over the period for which the underlying
services are rendered.

    On February 23, 1999, we issued two warrants to a consultant to purchase 60
thousand shares each for the exercise price of $0.01 and $3.25, respectively, in
connection with financing services rendered by the consultant. A fair value of
$335 thousand, computed on the basis of a Black-Scholes valuation model, was
ascribed to these warrants and was expensed at the time the services were
rendered. These warrants were exercised in February 1999 and April 1999,
respectively.

                      FOR THE YEAR ENDED DECEMBER 31, 1999

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

    In conjunction with the issuance of Convertible Debentures, we issued
five-year warrants to purchase 795 thousand shares of Common Stock, all of which
are outstanding at December 31, 1999. The fair value of these warrants was
determined to be $6.6 million and is being amortized over the term of the
Convertible Debentures. The total amortization of the fair value of the 795
thousand warrants in 1999 was $0.6 million. Included in the warrants for 795
thousand shares of Common Stock were warrants to purchase 745 thousand shares of
Common Stock that were issued to Investors. These warrants had a valuation of
$6.1 million and were recorded as a debt discount to the Convertible Debentures.

EMPLOYEE STOCK PURCHASE PLAN

    As part of an employee retention program, we established the Amended 1991
Employee Stock Purchase Plan, as Amended and Restated as of October 1, 1999 (the
"Stock Purchase Plan") to provide employees with an opportunity to purchase our
Common Stock through payroll deductions. A total of 1.275 million shares of
Common Stock were reserved for issuance to eligible employees under the Stock
Purchase Plan. The Stock Purchase Plan will terminate in 2011 unless sooner
terminated by the Board of Directors. Under this Stock Purchase Plan, our
employees, subject to certain restrictions, may purchase shares of Common Stock
at 85% of the lesser of the fair market value of the Common Stock on the date of
the beginning of the two-year offering or the end of the purchase period. During
1999, 1998 and 1997, 250 thousand shares, 116 thousand shares and 64 thousand
shares, respectively, were issued under the Stock Purchase Plan, and, at
December 31, 1999, 461 thousand shares were available for issuance.

STOCK INCENTIVE PLAN

    We have a 1999 Stock Incentive Plan (the "Stock Plan") that authorizes the
Board of Directors to grant incentive stock options, nonstatutory stock options,
stock purchase rights and stock bonuses to employees and consultants. The Stock
Plan authorizes the issuance of up to 7.916 million Common Shares, of which
1.447 million were available for grant as of December 31, 1999. Under the Stock
Plan, incentive stock options must be granted at fair market value at the date
of grant as determined by the Board of Directors or a committee thereof. Options
generally vest over a four-year period and are exercisable for a term of ten
years after issuance, unless otherwise determined by the Board of Directors or a
committee thereof.

    We have elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25), and related interpretations
in accounting for our employee stock options because the alternative fair value
accounting provided for under FAS Statement No. 123, "Accounting for Stock-Based
Compensation" (FAS 123), requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB 25, because the

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

fair value for these options and the fair value for the stocks issued under the
Stock Purchase Plan were estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1999,
1998 and 1997: risk-free interest rate of 5.88%, 4.25% and 5.41%, respectively;
a dividend yield of 0.0%; volatility factors of the expected market price of our
Common Stock of .82, .78, and .66, respectively; and a weighted-average expected
life of the option of five years.

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

    For purposes of pro forma disclosures, the estimated fair value of the
options issued under the Stock Plan is amortized to expense over the vesting
period of the options. The estimated fair value of the compensation benefit
received under the Stock Purchase Plan is expensed in the year of purchase. Our
pro forma information follows:

    Under the Stock Plan, stock may be sold and stock bonuses or rights to

that an employee is terminated prior to certain predetermined vesting dates. As
of December 31, 1999, 1998 and 1997, no shares were subject to repurchase.

    Realization of deferred tax assets is dependent on future earnings, if any,
the timing and amount of which are uncertain. Accordingly, a valuation allowance
in an amount equal to the net deferred tax assets as of December 31, 1999 and
1998 has been established to reflect these uncertainties. The deferred tax asset
valuation allowance increased by $4.1 million and $17.4 million in 1999 and
1998, respectively.

                      FOR THE YEAR ENDED DECEMBER 31, 1999

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

    Approximately $5.8 million of the valuation allowance results from tax
deductions under the stock option plans and will be credited to Common Stock
when recognized.

    At December 31, 1999, we had federal net operating loss and research and
development tax credit carryforwards of approximately $152.6 million and $3.7
million, respectively. We had state net operating loss and tax credit
carryforwards of approximately $36.5 million and $3.1 million, respectively.
These carryforwards will expire at various dates beginning in 2000 and through
2018.

    Because of the "change in ownership" provisions of the Internal Revenue
Code, a substantial portion of our net operating loss and tax credit
carryforwards may be subject to annual limitations. The annual limitations may
result in the expiration of net operating losses and tax credits before
utilization.

NOTE 7: DISCONTINUED OPERATIONS

    On December 15, 1999, we completed the sale of substantially all of our drug
delivery business to Ortho-McNeil Pharmaceutical, Inc. ("Ortho-McNeil"). We sold
all of our drug delivery business to Ortho-McNeil except two contracts relating
to a nicotine patch under development and one other early-stage project, both of
which were terminated prior to year end. Under the terms of the agreement, we
received $20.0 million in cash at closing, and Ortho-McNeil is obligated to pay
up to an additional $55.0 million in cash, contingent on the achievement of
certain milestones. The remaining contingent payments relate to the achievement
of certain technical, regulatory and commercialization milestones related to the
EVRA transdermal contraceptive patch. We are eligible to receive up to $14.8
million of these contingent milestones in the year 2000; however, because the
achievement of these milestones is not within our control, we cannot predict the
likelihood or timing of these contingent payments in the year 2000 and beyond.
The revenues of the drug delivery business were $12.3 million, $11.2 million and
$27.4 million for the years ended December 31, 1999,

1998 and 1997, respectively. The net income/(loss) of the drug delivery business
was $3.0 million, $1.0 million and $(35.3) million for the years ended
December 31, 1999, 1998 and 1997, respectively.

NOTE 8: BUSINESS SEGMENTS

    Prior to December 15, 1999, we operated in two business segments:
diagnostics and drug delivery. Both segments were engaged in development and
manufacture, utilizing proprietary technologies to satisfy unmet medical needs
cost effectively. The segments were strategic business units managed separately,
based on the differences in the technologies of their respective product lines.
On December 15, 1999, we completed the sale of substantially all of our drug
delivery business segment assets to Ortho-McNeil Pharmaceutical, Inc., except
for certain assets with a net book value of $505 thousand, of which assets with
a net book value of $205 thousand were written off prior to year end. The
remaining drug delivery assets are being held for sale at December 31, 1999 and
have a value of $300 thousand, which reflects management's best estimates of net
realizable value. All financial results related to the drug delivery business
are accounted for as discontinued operations in accordance with APB 30.

    The accounting policies of the business segments are the same as those
described in the summary of significant accounting policies. We do not currently
have a measure of interest income or interest expense by business segment. We
utilized the following information for the purpose of making decisions and
assessing segments' performance.

NOTE 9: CONVERTIBLE DEBT NOTES

SENIOR SUBORDINATED CONVERTIBLE NOTES

    In February 1998, we entered into Note Purchase Agreements with certain
institutional investors to issue and sell approximately $43.0 million of 4%
Senior Subordinated Convertible Notes Due in 2005 ("Notes"). On October 28,
1998, we restructured the Notes. Key provisions in the restructured

                                      F-21

                                  CYGNUS, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      FOR THE YEAR ENDED DECEMBER 31, 1999

                     (IN THOUSANDS, EXCEPT PER-SHARE DATA)

Notes included the October 1998 repayment of $18.5 million in principal
(reducing the principal balance from $43.0 million to $24.5 million), a delay in
the convertibility of the majority of the Notes to June 30, 1999 or after,
modification of the conversion prices of the Notes, our ability to redeem at par
at any time all or part of the new principal amount of the Notes, an increase in
the interest rate to 5.5% paid annually on the new principal balance and a
change in the final maturity of the Notes to October 1, 2000.

    The restructured Notes, which totaled $24.5 million, were divided into three
tranches. The first tranche had an original principal amount of $6.0 million and
was fully converted into Common Stock by January 1999 at $3.54 per share. The
second tranche also had an original principal amount of $6.0 million and was
fully converted into Common Stock on June 30, 1999 at $6.89 per share (such
conversion price determined by a market-based formula on February 1, 1999). The
third tranche of the restructured Notes had an original principal amount of
$12.5 million and could not have been converted into Common Stock until July 1,
1999, at a conversion price that would have been determined based on
market-based pricing formulas which contained look-back provisions. Also, under
the terms of the restructured Notes, if we issued a call before July 1, 1999 for
the redemption of the third tranche, the Note Holders would not be entitled to
convert any portion of that tranche. On June 29, 1999, we issued redemption
notices for the entire third tranche and, accordingly, the Note Holders were not
entitled to convert any portion of that tranche. On July 9, 1999, we paid $12.5
million in principal and $0.4 million in accrued interest to redeem the third
tranche. As a result, the remaining unamortized debt issuance costs of $1.1
million were expensed.

    On the date the Notes were restructured (October 28, 1998), the conversion
price for the first tranche was below the quoted market price of our Common
Stock. Consequently, we computed a beneficial conversion feature by comparing
the quoted market price of our Common Stock on that date ($6.06125) to the
conversion price of the first tranche ($3.5375) and then by multiplying the
difference by the number of shares (1.7 million) into which the first tranche
was convertible. The above computation resulted in a total charge of
$4.2 million, which was written off as interest expense at the date of
restructuring.

    In order to help finance the redemption of the third tranche discussed
above, and to provide additional capital, in 1999 we entered into two new
financing arrangements: a Convertible Debenture and Warrant Purchase Agreement
and a Structured Equity Line Flexible Financing Agreement.

CONVERTIBLE DEBT AGREEMENT

    On June 29, 1999, we entered into a Convertible Debenture and Warrant
Purchase Agreement with institutional investors ("Investors") to issue and sell
$14.0 million principal amount of 8.5% Convertible Debentures Due June 29, 2004
("Convertible Debentures"). These Convertible Debentures are convertible into
shares of Common Stock at any time at a conversion price of $12.705 per

share. We received gross proceeds of $14.0 million from the issuance of the
Convertible Debentures and incurred debt issuance costs of $0.5 million. With
the mutual agreement of the Investors and us, or if certain trading volume,
pricing and other conditions are met, we and/or the Investors will have the
right to require the sale to existing Investors of an additional $6.0 million in
additional aggregate principal amount of Convertible Debentures in two separate
tranches of $3.0 million each (each an "Additional Tranche"), provided that the
second Additional Tranche notice date may not be earlier than sixty days after
the first Additional Tranche notice date. The conversion price for each
Additional Tranche will be the average of the closing bid prices for the ten
trading days prior to and including the respective Additional Tranche notice
date and the ten trading days subsequent to the respective Additional Tranche
notice date ("Additional Closing Price") multiplied by 110%. On September 29,
1999 we received $3.0 million in gross proceeds from the issuance of the first
Additional Tranche due September 29, 2004, with a conversion price of $11.8663
(determined by the above market-based formula), and incurred debt issuance costs
of $0.1 million. Neither the June 29, 1999 nor the September 29, 1999
Convertible Debentures contained any beneficial conversion features.

    In conjunction with the issuance of Convertible Debentures in June, 1999,
and the first Additional Tranche in September 1999, we issued to the debenture
holders warrants to purchase approximately 606 thousand shares and 139 thousand
shares of Common Stock, at the exercise price of $13.86 per share and $16.18 per
share, respectively. Each tranche of warrants had a contractual term of
five years from the date of respective grant. At the respective dates of grant,
the fair values ascribed to these warrants were approximately $5.0 million and
$1.1 million, respectively, based on a Black-Scholes valuation model, and
recorded as debt discount and are being amortized as additional interest expense
over the debt term. We recorded amortization of $0.6 million in 1999. As of
December 31, 1999, the unamortized fair value amounted to $5.5 million. We will
be required to issue warrants if the second Additional Tranche of the
Convertible Debentures is sold. Such warrants will be priced at 150% of the
respective Additional Closing Price. The number of additional warrants to be
issued will be determined by dividing 50% of the respective Additional Tranche
by the respective Additional Closing Price.

    We also issued to the placement agent warrants to purchase 50 thousand
shares of Common Stock at the exercise price of $13.86 per share. At the date of
grant, the fair value ascribed to the warrants was approximately $417 thousand,
based on a Black-Scholes valuation model, and that amount was recorded as
deferred financing cost and is being amortized as additional interest expense
over the debt term. We recorded amortization of $42 thousand in 1999.

    The Convertible Debentures have a stated interest rate of 8.5% and an
effective interest rate of 18.20%. The effective interest rate includes a
non-cash charge of $6.6 million for the amortization of the implicit value of
warrants issued in connection with the Convertible Debentures.

STRUCTURED EQUITY LINE NOTES

    On June 30, 1999, we also entered into a Structured Equity Line Flexible
Financing Agreement ("Equity Line") with certain institutional investors
("Investors"). The Equity Line is effective for two years ("Commitment Period")
and allows us, at our sole discretion, to sell Common Stock with a maximum
aggregate issue price of $30.0 million over the Commitment Period. On June 30,
1999, we received net proceeds of approximately $3.8 million, after deducting
the issuance costs, from the sale of approximately 346 thousand shares of Common
Stock (the "Initial Investment"). The number of shares of Common Stock for the
Initial Investment was determined on the basis of the average closing bid price
for the ten trading days prior to June 30, 1999 ("Initial Investment Purchase
Price"). Under the terms of the Equity Line, over a period of eighty
trading days following June 30, 1999 ("Initial Period"), the Investors were
required to deliver purchase notices from time to time for the aggregate amount
of the Initial Investment ($4.0 million) to purchase shares of our Common Stock.
The per-share price for each such purchase notice equaled 98% of the average of
the two lowest daily trade prices during the six trading days immediately prior
to the respective purchase notice. The number of shares originally issued was
subject to an upward adjustment, if required, to match the aggregate number of
shares covered by the $4.0 million of purchase notices. We issued an additional
92 thousand shares to reflect the actual purchase prices on the purchase
notices.

    On September 29, 1999, we issued 361 thousand shares of Common Stock for
$4.0 million ("Additional Investment") pursuant to an amendment to the Equity
Line agreement which allowed for an Additional Investment period of 110 days
("Additional Period"). The terms for this Additional Investment are similar to
those applied to the Initial Investment, and the number of shares was adjusted
upwards at the end of the Additional Period, resulting in the issuance of an
additional 92 thousand shares of Common Stock.

    After the Initial Period and the Additional Period, on a monthly basis
("Investment Period"), we can elect, at our sole discretion, to sell up to $1.5
million ("Company Election") in additional shares of Common Stock. In addition
to the above and upon our approval, the Investors may also elect to purchase an
additional $1.0 million ("Investor Election") of Common Stock in each Investment
Period. In each Investment Period in which we elect to sell additional shares,
the Investors will from time to time issue purchase notices for the aggregate
amount of the Company Election and the Investor Election, if applicable. The
per-share price of Common Stock to be sold for each such purchase notice will
equal 98% of the average of the two daily low trade prices during the six
trading days immediately prior to the respective purchase notice. At the
beginning of each Investment Period, we can set a minimum sales price ("Floor
Price") for our Common Stock. The Investors may require the aggregate dollar
amount of the Company Election and Investor Election for any Investment Period
to be less than requested, based on certain market trading volume guidelines. In
December 1999, we sold 100 thousand shares of Common Stock for $1.5 million
pursuant to the

Equity Line. In January 2000, we sold an additional 59 thousand share of Common
Stock for $1.0 million pursuant to the Equity Line.

    In conjunction with the Equity Line, in January 2000 we issued five-year
warrants to the Investors to purchase 95 thousand shares of Common Stock at
$11.51 per share. The price of the warrants will be determined each calendar
year and will equal 120% of the weighted-average per-share sales price of all
shares of Common Stock sold pursuant to the Equity Line that year. The number of
shares will equal 1% of the aggregate proceeds received for all shares sold
pursuant to the Equity Line during the year. In January 2000, we issued warrants
to purchase 95 thousand shares of Common Stock. Warrants to purchase a minimum
of 120 thousand shares must be issued under the Equity Line and, if at the end
of the Commitment Period, warrants to purchase less than 120 thousand shares of
Common Stock have been issued, we must issue a warrant to purchase the number of
shares equal to the difference, at a price equal to 120% of the average exercise
price of all warrants previously issued pursuant to the Equity Line.

NOTE 10: RELATED PARTY TRANSACTIONS

    We do business with two companies, including Contract Manufacturing, Inc.,
that are principally owned by a Cygnus non-officer employee. This individual's
employment with us will terminate on March 31, 2000. The two companies primarily
design and build manufacturing equipment for the GlucoWatch system and
manufacture components of the GlucoWatch system. During 1999, we purchased
approximately $3.2 million of goods and services from these companies. As of
December 31, 1999, we had non-cancelable purchase commitments to these companies
totaling $0.7 million. During 1998, we purchased approximately $4.0 million of
goods and services from these companies. As of December 31, 1998, $1.0 million
was payable to these companies. During 1997, we purchased approximately $2.7
million of goods and services from these companies.

NOTE 11: CONCENTRATION OF CREDIT RISK

    We maintain our cash, cash equivalents and investments primarily with a bank
and two brokerage houses. This practice is consistent with our policy to
maintain high liquidity and to ensure safety of principal.

    As of December 31, 1999, 100% of the trade accounts receivable are due from
one customer. As of December 31, 1998, three customers accounted for
approximately 61%, 18% and 18%, respectively, of the trade accounts receivable.
The remaining balances of the 1998 trade accounts receivable are due from two
customers, which are large pharmaceutical companies. Generally, we do not
require any collateral on receivable balances.

NOTE 12: EMPLOYEE BENEFIT PLAN

    We have an employee savings plan ("Plan") that qualifies as a deferred
salary arrangement under Section 401(k) of the Internal Revenue Code covering
substantially all employees. The Plan provides for employee contributions up to
15% of their annual pre-tax compensation or to a maximum of 17% of the combined
pre-tax and after-tax compensation, as defined in the Plan. The Plan provides
for Cygnus to match a portion of the contributions. For the years ended
December 31, 1999, 1998 and 1997, we incurred defined contribution expense of
$0.08 million, $0.1 million and $0.08 million, respectively.

NOTE 13: LEGAL PROCEEDINGS

    On November 20, 1998, the American Arbitration Association issued a Final
Award, which was not appealable, in an arbitration proceeding between Cygnus and
Pharmacia & Upjohn relating to the Nicotrol patch. Pursuant to the findings from
the arbitration proceedings, we were awarded $4.3 million for prevailing in some
of our claims, and Pharmacia was awarded $1.6 million for prevailing on some of
their claims. Accordingly, Cygnus realized a net amount of $2.7 million in 1998.
The Nicotrol patch business was sold to Ortho-McNeil as part of our drug
delivery sale.

    On December 11, 1997, the International Court of Arbitration issued a Final
Award, which was not appealable, in an arbitration matter between Sanofi, S.A.
and Cygnus relating to transdermal hormone replacement therapy systems. This
Final Award was entered as a judgment of the U.S. District Court for the
Northern District of California. Although the drug delivery business was
subsequently sold to Ortho-McNeil, the following payments remain with Cygnus:
(i) the $14.0 million cash payment already made by Cygnus to Sanofi in
January 1998, (ii) payments of an aggregate amount equal to $17.0 million,
commencing in 2001 and ending in 2005 ($2.0 million for the year 2001,
$3.0 million for the year 2002, $4.0 million for the year 2003, $4.0 million for
the year 2004 and $4.0 million for the year 2005), and (iii) a convertible
promissory note in the principal amount of $6.0 million, issued in
December 1997, payable in full at the end of four years and bearing interest at
6.5% per annum. (The note will be convertible into our Common Stock at Sanofi's
option, exercisable at any time during the four year term, at a conversion rate
of $21.725 per share.) The underlying agreement, which was the subject matter of
the arbitration, was terminated on December 15, 1999.

                                    SUBLEASE


         THIS SUBLEASE ("Sublease") is entered into as of the 15th day of
December, 1999 between CYGNUS, INC., a Delaware corporation ("Sublandlord"), and
ORTHO-McNEIL PHARMACEUTICAL, INC., a Delaware corporation ("Subtenant"), with
reference to the following facts:

         A. Pursuant to that certain Ten-Year Industrial Net Lease Agreement
dated September 27, 1988 ("Lease"), between Seaport Centre Venture Phase I, a
California general partnership, as Landlord ("Landlord"), and Cygnus, as Tenant,
as amended by the First Amendment to Ten-Year Industrial Net Lease Agreement
dated May 15, 1992 ("First Amendment"), the Second Amendment to Ten-Year
Industrial Net Lease Agreement dated August 8, 1992 ("Second Amendment"), and
the Third Amendment to Ten-Year Industrial Net Lease Agreement dated June 9,
1998 ("Third Amendment") (collectively, the "Master Lease"), a copy of which is
attached hereto as Exhibit A and made a part hereof, Sublandlord leased from
Landlord and Landlord leased to Sublandlord approximately 32,038 rentable square
feet of space consisting of two (2) buildings located at 701 Galveston Street

         B. Subtenant desires to sublet from Sublandlord the portion of the
Master Lease Premises commonly known as 701 Galveston Street, Redwood City,
California, consisting of approximately 20,880 rentable square feet, as more
particularly set forth in EXHIBIT B attached hereto and made a part hereof
("Subleased Premises"), and Sublandlord does hereby sublet the same to Subtenant
upon the terms, covenants and conditions hereinafter set forth.

         NOW, THEREFORE, in consideration of the covenants herein contained, and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties do hereby agree as follows:

         1. SUBLEASE. Sublandlord does hereby sublease and demise to Subtenant,
and Subtenant does hereby hire and take from Sublandlord, all of the Subleased
Premises subject to: (i) the covenants, agreements, terms, provisions and
conditions of this Sublease for the term hereinafter stated; and (ii) the
covenants, agreements, terms, provisions and conditions of the Master Lease.
Subtenant hereby acknowledges receipt of the copy of the Master Lease attached
hereto as EXHIBIT A. Sublandlord represents to Subtenant that the copy of the
Master Lease attached hereto is true and correct and that there are no
amendments or modifications to such document other than as so attached.

15, 1999 (the "Commencement Date") and shall end December 10, 2003, or on such
earlier date upon which said Term may expire or be terminated pursuant to any of
the conditions of limitation or other provisions of this Sublease, the Master
Lease, or pursuant to law.


                                     - 1 -

         3. USE. Subtenant shall use the Subleased Premises in strict
conformance with allowable uses under the Master Lease and for no other purpose
without the prior written consent of Sublandlord and Landlord. Subtenant hereby
represents and warrants that it shall not use any Hazardous Materials (as
defined in Paragraph 9 of the Master Lease and Rider No. 1) within the Subleased
Premises, except for those materials that Sublandlord is permitted to use under
the Master Lease, and that Subtenant shall strictly comply with all the terms
and conditions of Paragraph 9 and Rider No. 1 of the Master Lease as
incorporated herein pursuant to Paragraph 5 below.

         4. RENT.

         A. Subtenant shall pay Sublandlord as monthly base rent for the
Subleased Premises on the first (1st) day of each calendar month during the Term
of this Sublease according to the following schedule:

                   Months                               Amount
                   ------                               ------
             12/15/99-01/10/00                       $41,281.78
             1/11/00-12/10/00                        $47,397.60
             12/11/00-12/10/01                       $48,650.40
             12/11/01-12/10/02                       $50,112.00
             12/10/02-12/10/03                       $51,782.40



The base rent for the December 1999 period shall be due and payable on the
mutual execution of this Sublease. All rent shall be payable, in advance,
without any offset, deduction, or abatement, except as otherwise set forth in
this Sublease. The base rent shall be a triple net rent, and Subtenant shall
also be fully responsible for Additional Rent assessed against the Subleased
Premises pursuant to Paragraph 4.B. below.

         B. Subtenant shall also pay to Sublandlord all Additional Rent for the
Subleased Premises for each calendar month of the Term. If Landlord bills
subtenant for any Additional Rent, Subtenant shall pay the same to Landlord in
accordance with the Master Lease. If Sublandlord bills subtenant for any
Additional Rent, Subtenant shall pay the same to Sublandlord within ten (10)
days thereafter. If Subtenant fails to reimburse Sublandlord for Additional Rent
within such ten (10) day period, Subtenant shall also pay interest on such
amount at ten percent (10%) per annum from the date due until paid. As used in
this Sublease, the term "Additional Rent" shall mean all payments that Subtenant
is required to pay under this Sublease other than monthly base rent, together
with all payments that Sublandlord is required to pay to Landlord with respect
to the Subleased Premises during the Term pursuant to the Master Lease other
than monthly base rent. Subtenant shall, at its own expense, contract for and
pay directly for its telephone service for the Subleased Premises and all
utilities as set forth in Paragraph 8 of the Master Lease, Paragraph 6(c) of the
Second Amendment and Paragraph 7 of the Third Amendment. For purposes herein,
"Rent" shall include all monthly base rent, Additional Rent and all utility
expenses.

         5. INCORPORATION OF MASTER LEASE. Except to the extent that they are
inapplicable to, or modified by, or excluded by, the terms of this Sublease, all
of the covenants, agreements, terms, provisions and conditions of the Master
Lease are hereby incorporated into and made a part of this Sublease. Except to
the extent that they are inapplicable to, or modified by, the terms of this
Sublease, the rights and obligations contained in the Master Lease are hereby
imposed upon the respective parties hereto, Sublandlord being substituted for
"Landlord" named in the Master Lease, Subtenant being substituted for the
"Tenant" named in the Master Lease, and "Subleased Premises" being substituted
for the "Premises" named in the Master Lease, except for Paragraphs 1, 2, 3, 4,
5 and 6, Paragraph 26(g), the last sentence of the first paragraph of Paragraph
28, Paragraph 30, Paragraph 34(b), Paragraph 35, Paragraph 38, Paragraph 39,
Paragraph 41, Exhibits A, A-1, B, and C of the Lease; the First Amendment in its
entirety; the Second Amendment in its entirety; and all references to "Building
3 and 5" in the Third Amendment, and Section 2, Section 4(b)(iii), 4(b)(iv),
Section 4(c), Section 5, Section 6(ii), Section 8, Section 9, Section 10,
Section 13, Section 14, Section 15 and Section 16 of the Third Amendment, which
are hereby deleted from this Sublease. Except as so excluded, inapplicable or
modified, all acts and obligations to be performed and all of the terms and
conditions to be observed by Sublandlord as Tenant under the Master Lease with
respect to the Master Lease Premises shall be performed and observed by
Subtenant with respect to the Subleased Premises.

         6. SUBORDINATION RIGHTS TO THE MASTER LEASE. This Sublease and
Subtenant's rights under this Sublease shall at all times be subject and
subordinate to the underlying Master Lease. If any conflict between the Master
Lease and the Sublease occurs, the Master Lease will control, except as
inapplicable to, or modified by, the terms of this Sublease or excluded from the
incorporation provisions of Paragraph 5 hereof. Subtenant acknowledges and
agrees that any termination of the underlying Master Lease shall extinguish the
Sublease at Landlord's discretion, without liability to Sublandlord; provided,
however, that such termination is not due to the default of Sublandlord under
the Master Lease or to the voluntary surrender by Sublandlord of its rights
under the Master Lease. Subtenant shall have no right to assign the Sublease or
further sublet the Subleased Premises without the prior written consent of
Sublandlord and the Landlord and in strict conformance with the terms of
Paragraph 15 of the Master Lease.

         7. MODIFICATIONS TO INCORPORATED TERMS OF MASTER LEASE. Subtenant
agrees that, notwithstanding anything to the contrary in this Sublease and the
Master Lease, Sublandlord shall not be required to provide any of the services,
make any of the repairs (including, without limitation, maintenance and repairs
required pursuant to Paragraph 12(b), Paragraph 24 and Paragraph 25 of the
Master Lease), improvements or restorations, or perform any of the other
obligations that the Landlord has agreed to provide or make or cause to be
provided or made under the provisions of the Master Lease, respectively,
including, without limitation, repairs, utilities, insurance and indemnification
obligations, and Subtenant shall rely upon and look solely to the Landlord for
the provision or making thereof. Notwithstanding the foregoing, Sublandlord
agrees: (i) to maintain the insurance with respect to Paragraph 20 of the Master
Lease as applicable to the Master Lease Premises and Sublandlord's personal
property; and (ii) that the provisions of Paragraph 19 of the Master Lease shall
apply as between Sublandlord and Subtenant. Sublandlord, upon request of
Subtenant, agrees to use reasonable efforts to cause


                                     - 3 -
<PAGE>

Landlord to observe and/or perform any such obligations; provided, however,
without limiting the generality of the foregoing, the obligation of Sublandlord
to use "reasonable efforts" shall not be construed as requiring Sublandlord to
pay any money or incur any cost or liability beyond that which it has under the
Master Lease or to institute or prosecute any legal action or proceeding. If
Landlord shall still default in the performance of any such obligations or any
representations under the terms of the Master Lease, Sublandlord's obligations
in respect thereto shall be to use its diligent efforts to assist Subtenant
hereunder in any claims or proceedings against Landlord as long as Subtenant
agrees to reimburse Sublandlord for all costs associated with such actions or
proceeding under the Master Lease.

         8. CONDITION OF SUBLEASED PREMISES.

         A. Sublandlord shall deliver the Subleased Premises to Subtenant in its
current "as-is" condition, and Subtenant shall rely solely on Subtenant's own
inspection of the Subleased Premises and the physical condition thereof,
including, without limitation, accessibility and location of utilities, the
condition of improvements and the existence of hazardous materials, and not on
any representations or warranties of Sublandlord or its agents, employees or
contractors, whether express or implied except as set forth in the next
sentence. Notwithstanding the foregoing, Sublandlord shall, at its own cost,
deliver the Subleased Premises in broom clean condition, with all furniture in
place.

         B. Subtenant shall not make or suffer to be made any alterations,
additions or improvements (collectively, "Alterations") in, on or to the
Subleased Premises without the prior written consent of Sublandlord and
Landlord, which shall not be unreasonably withheld. All Alterations shall be
performed in strict compliance with Paragraph 11 of the Master Lease. In the
event Sublandlord consents to the making of any such Alterations by Subtenant,
the same shall be made by Subtenant at Subtenant's sole cost and expense, and
any contractor or person selected by Subtenant to make the same shall first be
approved in writing by Sublandlord and Landlord. Upon the expiration or sooner
termination of this Sublease, Subtenant shall, upon demand by Sublandlord and
Landlord, at Subtenant's sole cost and expense, forthwith and with all due
diligence, remove any Alterations made or paid for by Subtenant, and repair and
restore the Subleased Premises to their original condition, ordinary wear and
tear excepted. In addition, Subtenant hereby assumes all of Sublandlord's
restoration obligations to Landlord pursuant to Paragraph 28 of the Lease (as
modified by Section 10 of the Third Amendment). Finally, Sublandlord will
cooperate with Subtenant to acquire Landlord's consent to any Alterations, but
Subtenant acknowledges that Sublandlord makes no representation as to Landlord's
willingness to approve such Alterations and shall have no liability for
Landlord's failure to provide such approval.

         C. Subtenant shall, at its sole cost, make all modifications,
alterations and improvements to the Subleased Premises and Building that are
required by any applicable city, state or federal rule, law, regulation or order
because of: (i) Subtenant's particular use of the Subleased Premises or
Building; (ii) Subtenant's application for any permit or governmental approval;
or (iii) Subtenant's making of any Alterations to or within the Subleased
Premises. All other improvements or capital expenditures relating to
modifications, alterations or


                                     - 4 -
<PAGE>

improvements to the Subleased Premises or Building shall be governed by the
terms and conditions of Paragraph 11 of the Master Lease.

         D. Sublandlord is in compliance with all laws, ordinances, rules, and
regulations affecting the Subleased Premises, including any alterations or
modifications performed thereon by Sublandlord.

         9. INSURANCE. Subtenant, at its sole cost and expense, shall obtain and
keep in full force and effect during the entire term of this Sublease such
insurance, and in such amounts, as are required under Paragraph 20 of the Master
Lease. Sublandlord and Landlord shall be named as additional insured parties
under any such policy of insurance. Subtenant and Sublandlord shall each obtain
from their respective insurers hereof a waiver of all rights of subrogation as
set forth in Paragraph 19 of the Master Lease and the other waivers contained in
Paragraph 19 shall apply as between the Subtenant and Sublandlord.


        10. TIME LIMITS. The time limits provided in the Master Lease for the
giving of notices, making demands, performance of any act, condition, or
covenant, or the exercise of any right or remedy, are changed solely for the
purpose of incorporation of the terms of this Sublease by lengthening or
shortening the same in each instance by three (3) days (or two (2) days for any
three (3) day period), as appropriate; so that notices may be given, demands
made, or any act, condition, or covenant performed, or any right or remedy
exercised, by Sublandlord or Subtenant, as the case may be, within the time
limit relating thereto contained in the Master Lease.

        11. NOTICES. All notices and other communications that are required or
desired to be given by either party to the other hereunder shall be in writing
and shall be sent by United States registered or certified mail, postage
prepaid, return receipt requested, addressed to the appropriate party at its
address as such party shall have last designated by notice to the other party in
the manner herein provided. Notices and communications to Sublandlord shall be
sent to:

this Sublease unless such is in writing and signed by both parties.

        14. INDEMNIFICATION


         A. Subtenant shall indemnify, defend, protect and hold harmless
Sublandlord and Sublandlord's officers, directors, agents and employees
(collectively, "Sublandlord's Parties") from and against all liability, cost,
damage and expense (including, without limitation, reasonable attorneys' fees)
arising from either: (i) the negligence, willful misconduct, or breach of this
Sublease by Subtenant or Subtenant's officers, directors, agents or employees
(collectively "Subtenant's Parties"), (ii) the use of the Subleased Premises by
Subtenant or Subtenant's Parties and any related claims for Subtenant's use of
the Subleased Premises solely for a professional office and administrative uses;
(iii) the construction of the Alterations or any claims for work or labor
performed, or for materials or supplies furnished to or at the request of
Subtenant in relation thereto; or (iv) the use, release or disposal of Hazardous
Materials by Subtenant or Subtenant's Parties provided, however, that the
indemnification provided in this Paragraph 15.A. shall not apply to the extent
that any liability, cost, damage or expense arises from the negligence, willful
misconduct, or breach of this Sublease by Sublandlord or Sublandlord's Parties.

         B. Sublandlord shall indemnify, defend, protect and hold harmless
Subtenant and Subtenant's Parties from and against all liability, cost, damage
and expense (including, without limitation, reasonable attorneys' fees) arising
from either (i) the negligence, willful misconduct, or breach of this Sublease
by Sublandlord or Sublandlord's Parties; (ii) the use of the Master Lease
Premises by Sublandlord or Sublandlord's Parties; (iii) the use, release or
disposal of Hazardous Materials by Sublandlord or Sublandlord's Parties in the
Building; provided, however, that the indemnification provided in this Paragraph
15.B. shall not apply to the extent that any liability, cost, damage or expense
arises from the negligence, willful misconduct, or breach of this Sublease by
Subtenant or Subtenant's Parties, or (iv) any environmental condition that
existed prior to the Commencement Date of this Sublease due to the storage,
production, for distribution of environmentally hazardous materials at the
Subleased Premises.

         C. The terms of this Paragraph 15 shall survive the expiration or
termination of this Sublease and shall be an addition to, and not a replacement
of, the terms of Paragraph 17 of the Master Lease and Paragraph 1.7 of Rider No.
1.

        15. MISCELLANEOUS


         A. Subtenant shall be entitled to use, on a nonexclusive basis and free
of charge, all of the parking stalls available for use by Sublandlord for the
Subleased Premises at the ratio set forth in the Master Lease.

         B. Subtenant shall be responsible and shall pay to Sublandlord upon
demand, any late charges owed arising out of Subtenant's late payment of Rent
hereunder.

         C. This Sublease may be executed in counterparts each of which when
executed shall constitute but one original, and all of which together shall
constitute a single agreement.


                                     - 7 -
<PAGE>

         D. Subtenant shall have the right, at its sole cost and expense, to
install: (i) door signage at the entrance to the Premises. All signage shall be
subject to the terms of the Master Lease and the consent of Sublandlord,
Landlord, and the City of Redwood City.

         E. Should Sublandlord or Subtenant engage the services of a Broker in
connection with this Sublease, each party shall be responsible for its own
Broker's commission.

         F. Should Subtenant or any of its successors in interest, holdover the
Subleased Premises, or any part thereof, after the expiration of the Term of
this Sublease, unless otherwise agreed to in writing, such holding over shall
constitute and be construed as tenancy from month-to-month only at a monthly
rent equal to twice the monthly base rent owed during the final year of the Term
of this Sublease as the same may be extended from time to time. This inclusion
of the preceding sentence shall not be construed as Sublandlord's permission for
Subtenant to holdover.

         G. Sublandlord represents to Subtenant that the Master Lease is in full
force and effect and that, to the best of Sublandlord's knowledge, without duty
of inquiry, no default or event that, with the passing of time or the giving of
notice or both, would constitute a default, exists on the part of Sublandlord,
and to the best of Sublandlord's knowledge, without duty of inquiry, the
Landlord thereunder. Sublandlord agrees to maintain the Master Lease in full
force and effect except to the extent its failure to maintain the Master Lease
is due to the failure of Subtenant to comply with its obligations under this
Sublease provided Subtenant receives prior written notice from Sublandlord as
required by the Master Lease (as modified by Paragraph 11 above). During the
Term, Sublandlord shall not enter into any amendment of the Master Lease that
during the initial term, would materially diminish Subtenant's rights or
materially increase Subtenant's obligations hereunder.

                            PRODUCT SUPPLY AGREEMENT

         This Agreement (the "Agreement") is made this 15th day of July 1997
("Effective Date"), by and between Cygnus, Inc., a Delaware
corporation("Cygnus"), and Contract Manufacturing, Inc. ("CMI"), a Michigan
corporation, and is made with reference to the following facts.


          RECITALS

         A.   Cygnus is in the course of developing a product for the
non-invasive measurement of human blood glucose levels known as the
"Glucowatch", and

         B.   Two components of the Glucowatch are a Glucopad and a biosensor,
and

         C.   Cygnus desires to market to end users, packaged together, a
Glucopad, physically contained within rails, known as a "corral" and a
biosensor, and

         D.   CMI is willing to accept, from sources of Cygnus' selection,
supply of Glucopad material (supplied in rolls) and biosensors, and (i)
manufacture finished Glucopads by cutting the Glucopad material and inserting
the material into corrals which CMI would manufacture (ii) combine the pads and
biosensors protected by suitable release liner backings, and (iii) supply the
combination in final consumer protective packaging.

         WHEREFORE, the parties do hereby agree as follows:


1.       DEFINITIONS

         1.1.     "CONSUMER PACKAGE UNIT" shall mean a single package which
                  contains a Glucopad and a biosensor as more particularly
                  specified in Exhibit 1.

         1.2.     "GLUCOWATCH" shall mean Cygnus' Reverse Iontophoresis Product
                  currently under development for the measurement of human blood
                  glucose values and any modifications, improvements,
                  evolutions, and for future versions thereof.

         1.3.     "GLUCOPAD" shall mean laminate material, supplied in rolls cut
                  into pads and placed within a corral as more particularly
                  specified in Exhibit 1.

         1.4.     "MANUFACTURING COST" for a Consumer Package Unit means the
                  following costs (as determined in accordance with GAAP):
                  both direct and indirect costs specifically attributable to
                  the production of such components (excluding , freight
                  charges, sales taxes and duties). Direct costs are personnel,
                  supplies, materials purchased by CMI, contracted and outside
                  services costs specifically attributable to the applicable
                  materials or activities. Raw Materials are not part of
                  Manufacturing Cost. Indirect costs are (i) utility,
                  facility-related and machine maintenance expenses and (ii)
                  personnel, supplies and material expenses of internal services
                  from other departments (including general management and
                  administration), in each case, only to the extent specifically
                  attributable to the applicable materials or activities.

         1.5.     "TERM" shall mean the period beginning at the Effective Date
                  of this Agreement and ending five years after the date of the
                  first commercial sale of Consumer Package Units anywhere in
                  the world.

         1.6.     "RAW MATERIALS" shall mean those components required to build
                  a Consumer Package Unit as set forth in the bill of materials
                  specified in Exhibit 1.

2.       PURCHASE AND SALE

         2.1.     SUPPLY. For the Term hereof CMI agrees to supply Consumer
                  Package Units to Cygnus as provided in this Agreement.

         2.2.     PURCHASE PRICE. The purchase price for Consumer Package Units
                  shall be [CONFIDENTIAL TREATMENT REQUESTED]:

         Annualized Production Volume:           Maximum
         Consumer Package Units/12 Month Period  Price/Consumer Package Unit
         --------------------------------------  ---------------------------

         [CONFIDENTIAL TREATMENT REQUESTED]  [CONFIDENTIAL TREATMENT REQUESTED]


         2.3.     COST REDUCTION. CMI and Cygnus will work to reduce the
                  cost of Consumer Package Units. Routine reductions in the
                  Manufacturing Cost due to things such as volume increases or
                  "learning curve" gains in efficiency will result in lower
                  pricing according to Section 2.2 above. If CMI, through it's
                  own effort, reduces the cost of the Consumer Package Units as
                  a result of a capital improvement to the Equipment (as defined
                  in Section 7.1 below), which proposal of such improvement
                  shall be submitted to Cygnus in writing and approved by Cygnus
                  in writing prior to implementation, the benefits from the cost
                  reduction effort will be shared equally. In such instance of
                  capital improvement to the Equipment, CMI's markup will be
                  increased while the maximum price will be reduced accordingly
                  in all annualized production volume ranges. All new pricing
                  resulting from cost reduction efforts shall be amended to this
                  Agreement.

         2.4.     MATERIAL WASTAGE. CMI agrees that material wastage shall not
                  exceed a maximum of [CONFIDENTIAL TREATMENT REQUESTED] for
                  each item of material at the commencement of supply and shall
                  not exceed a maximum of [CONFIDENTIAL TREATMENT REQUESTED]
                  commencing [CONFIDENTIAL TREATMENT REQUESTED] after the
                  commencement of supply. In the event wastage exceeds the
                  maxima specified in this Section, Cygnus shall be entitled to
                  a credit equal to the full cost of any wasted material in
                  excess of the maxima specified above. Material wastage shall
                  not include defective material supplied by vendors.

         2.5.     MANUFACTURING REPORTS. Within fifteen (15) days of the end of
                  each month, CMI shall provide Cygnus with a report, in an
                  electronic format compatible to Cygnus' system, indicating for
                  such month (i) the quantity of Consumer Package Units produced
                  and shipped, (ii) the Manufacturing Cost of such Consumer
                  Package Units (including quantity and cost for each component
                  of such Manufacturing Cost), (iii) the amount of material
                  wastage for each material, and (iv) such other information as
                  shall be requested by Cygnus from time to time. CMI and Cygnus
                  will work together to develop a method to transfer this
                  information electronically. CMI will use a system that is
                  compatible with Cygnus' system.


3.       CONSUMER PACKAGE UNIT SPECIFICATIONS. Consumer Package Units shall
         conform to the specifications set forth in Exhibit 1, as amended from
         time to time ("Specifications"). Cygnus may modify the Specifications
         in Exhibit 1, from time to time in its sole discretion. It shall give
         written notice of any change in the Specifications to CMI, which change
         shall become effective within forty-five (45) days of such notice. All
         such changes shall be forwarded in writing by Cygnus to CMI to the
         attention of the Production Manager and the Quality Assurance Manager.
         Provided, however, if CMI in good faith determines that it would be
         commercially unreasonable to supply Consumer Package Units meeting any
         such changed Specification, it may give written notice of such
         inability to supply to Cygnus within fifteen (15) days of the change
         notice. Failure to give such notice within this fifteen (15) day period
         shall be deemed to be acceptance of the

                                       2
<PAGE>

         Specification change. Upon giving of timely notice of such inability to
         supply, CMI shall be relieved of its obligation to accept orders
         according to the changed Specification.


4.       PURCHASES AND PURCHASE ORDER PROCEDURE

         4.1.      ORDERS AND FORECASTS. With respect to Consumer Package Units
                   which Cygnus wishes to purchase from CMI, prior to the first
                   month in which annualized production volume reaches
                   [CONFIDENTIAL TREATMENT REQUESTED] Consumer Package Units per
                   year, Cygnus will order Consumer Package Units on a lot by
                   lot basis. Cygnus shall deliver to CMI at least two (2) full
                   months prior to the month in which it wishes to take
                   delivery, Cygnus' firm order (which firm orders must be in
                   writing) and requested delivery date ("Delivery Date") for a
                   lot of Consumer Package Units. Immediately following the
                   first month in which annualized production volume reaches
                   [CONFIDENTIAL TREATMENT REQUESTED] Consumer Package Units per
                   year, Cygnus shall deliver to CMI at least one (1) full month
                   prior to the month in which it wishes to take delivery,
                   Cygnus' firm order (which firm orders must be in writing) and
                   requested delivery dates ("Delivery Dates") for such Consumer
                   Package Units for the month and a forecast of its quantity
                   requirements for such Consumer Package Units for the
                   subsequent eleven (11) months. Thereafter, Cygnus shall
                   deliver to CMI within five (5) days after the beginning of
                   each calendar month, Cygnus' firm order and Delivery Dates
                   for such Consumer Package Units for the next month and a
                   forecast of its quantity requirements for such Consumer
                   Package Units for the subsequent eleven (11) months. If a
                   required forecast or order for a one (1) month period is not
                   timely submitted for Consumer Package Units, the immediately
                   preceding forecast for that month shall become the new
                   forecast or order; if there is no preceding forecast for a
                   month, the forecast or order for the immediately preceding
                   month shall become the forecast or order. All forecasts are
                   non-binding. All firm orders are binding.

         4.2.      DELIVERY DATE. CMI will provide a firm scheduled delivery
                   date and an order acknowledgment promptly after receipt of
                   Cygnus' firm order. CMI will meet each firm scheduled
                   delivery date, but will not be liable for failure to do so
                   due to an event of force majeure (as defined in Section 15.11
                   below) or Cygnus' firm order not being received according to
                   the provisions of 4.1 above. If an event of force majeure
                   occurs, CMI may not reduce production or shipment of Consumer
                   Package Units for Cygnus by any amount exceeding the amount
                   of reduction caused by the force majeure event. Other than in
                   the case of an event of force majeure or Cygnus' firm order
                   not being received according to the provisions of 4.1 above,
                   CMI shall be solely responsible for any costs associated with
                   expediting materials in order to meet the scheduled delivery
                   date for each firm order (including, without limitation,
                   overtime charges, fees required to expedite materials or
                   services used in manufacturing and incremental transportation
                   costs), provided that Cygnus has complied with the terms of
                   this Agreement in placing such order.

         4.3.     TITLE AND RISK OF LOSS: PAYMENT. All shipments shall be FOB
                  Origin, Prepaid and Charged Back. Title and risk of loss shall
                  remain with CMI until Consumer Package Units have been
                  delivered to a common carrier for shipment. All of CMI's costs
                  for transportation, shipping and transportation insurance
                  expenses shall be invoiced to and paid by Cygnus.

         4.4.     PAYMENT. Prior to the first month in which the annualized
                  production volume reaches [CONFIDENTIAL TREATMENT REQUESTED]
                  Consumer Package Units per year, CMI shall invoice Cygnus for
                  shipped Consumer Package Units, in accordance with Section 2.
                  The payment terms for these shipments shall be [CONFIDENTIAL
                  TREATMENT REQUESTED] upon receipt of CMI's order
                  acknowledgment and invoice and [CONFIDENTIAL TREATMENT
                  REQUESTED] within thirty (30) days of receipt of Consumer
                  Package Units.

                  Immediately following the first month in which annualized
                  production volume reaches [CONFIDENTIAL TREATMENT REQUESTED]
                  Consumer Package Units per year, CMI shall


                                       3
<PAGE>

                  invoice Cygnus for shipped Consumer Package Units in
                  accordance with Section 2 within thirty (30) days of shipment.
                  Within thirty (30) days of receipt of Consumer Package Units,
                  Cygnus shall pay CMI's invoice for Consumer Package Units.

         4.5.     QUARTERLY RECONCILIATION. No later than ten (10) working days
                  after the end of each of Cygnus' fiscal quarters during the
                  Term hereof, CMI shall prepare a quarterly reconciliation of
                  all Manufacturing Costs and Consumer Package Units provided by
                  CMI to Cygnus. This information will be provided by CMI to
                  Cygnus in an electronic format that is compatible with Cygnus'
                  system.

         4.6.     REIMBURSEMENT OF COST BY CYGNUS. In the event Cygnus has not
                  provided CMI with any firm orders, as provided in Section
                  4.1, by [CONFIDENTIAL TREATMENT REQUESTED], Cygnus and CMI
                  will develop a plan to reimburse CMI for costs incurred in
                  order to maintain readiness of the manufacturing facility
                  for a period of time to be determined by Cygnus.

         4.7.     CONFLICTING TERMS. In ordering and delivering Consumer Package
                  Units, CMI and Cygnus may use their standard forms, but
                  nothing in such forms shall be construed to amend or modify
                  the terms of this Agreement.


5.       QUALITY

         5.1      QUALITY CONTROL. Prior to each shipment of Consumer Package
                  Units, CMI shall perform or cause to be performed quality
                  control procedures that are calculated to verify that the
                  units to be shipped conform with the Specifications for such
                  Consumer Package Units as determined under Section 3 hereof.
                  Each shipment of Consumer Package Units shall be accompanied
                  by a Quality Assurance Analytical Certificate of Conformance
                  ("Q.A. Certificate of Conformance").

         5.2.     REJECTION. Cygnus shall have sixty (60) days following the
                  day on which it receives a shipment to reject same because
                  all or part of the shipment fails to conform to the
                  applicable Specifications or otherwise fails to conform to
                  the warranties given by CMI herein, by giving written
                  notice to CMI specifying the manner in which all or part of
                  such shipment fails to meet the foregoing requirements. If
                  Cygnus timely rejects all or part of a shipment, CMI is
                  responsible for replacing the defective units at its
                  expense. CMI will be solely responsible for any
                  transportation charges pertaining to the return and
                  reshipping of rejected Consumer Product Units.

         5.3.     LATENT DEFECTS. It is recognized that it is possible for a
                  shipment of Consumer Package Units to have defects ("defects"
                  meaning that such Consumer Package Units fail to conform to
                  the applicable Specifications or otherwise fail to conform to
                  the warranties given by CMI herein) which would not be
                  discoverable upon reasonable physical inspection or testing
                  (the "Latent Defects"). As soon as either party becomes aware
                  of a Latent Defect in any lot or batch of Consumer Package
                  Units, it shall immediately notify the other party and the lot
                  or batch involved, at Cygnus' election, shall be deemed
                  rejected as of the date of such notice. CMI shall be
                  responsible for replacing all defective units involved at its
                  expense and shall reimburse Cygnus for its costs of accepting
                  returns from its customers and shall be responsible for all
                  costs reasonably incurred by Cygnus in recalling the Consumer
                  Package Units having Latent Defects. At its election, Cygnus
                  may recover moneys to which it may become entitled under this
                  Section by deducting same from amounts then due or that may
                  subsequently become due to CMI from Cygnus hereunder.

         5.4.     ISO 9002; QUALITY CONTROL SYSTEM. CMI shall obtain IS0 9002
                  certification of the facility used to manufacture Consumer
                  Package Units no later than [CONFIDENTIAL TREATMENT
                  REQUESTED]. CMI shall, at all times during the performance of
                  its manufacturing and supply

                                       4

<PAGE>

                  obligations under this Agreement, manufacture all Consumer
                  Package Units in compliance with, and maintain a quality
                  control system that meets the requirements of, ISO 9002 and
                  all applicable Good Manufacturing Practices which are in force
                  or hereinafter adopted by the FDA or any successor agency
                  thereto ("GMP"). CMI shall at all times take such additional
                  measures as are necessary to maintain a quality control system
                  designed to identify, correct and prevent quality deficiencies

6.       MINIMUM QUANTITIES

         6.1.     MINIMUM. [CONFIDENTIAL TREATMENT REQUESTED]

         6.2.     REMEDY FOR FAILURE TO PURCHASE. If in any Minimum Year,
                  Cygnus' firm orders shall require shipment of less than the
                  Minimum during the Minimum year, CMI shall be entitled to a
                  termination election ("Elective Termination") as provided
                  herein. No later than April 15 following the Minimum Year in
                  which the Minimum was not met, CMI may give written notice of
                  Elective Termination to Cygnus. CMI's right to give notice of
                  Elective Termination shall not extend beyond April 15 of any
                  year in which it shall be entitled to give notice and any
                  notice given untimely shall be void. Upon the giving of timely
                  notice of Elective Termination, Cygnus shall be relieved of
                  any requirements for firm orders under Section 4 hereof and
                  shall have thirty days after receipt of the notice of Elective
                  Termination to submit revised firm orders, which shall be
                  binding on both parties for the period from the date of notice
                  of Elective Termination through October 1 of that year.

6.3.              EXCLUSIVENESS OF REMEDY. The sole remedy for CMI in the event
                  of a failure to fulfill Minimums in a Minimum Year, shall be
                  an election to terminate as provided in Section 6.2 above and,
                  more particularly, CMI shall have no remedy for monetary
                  damages of any kind, regardless of the cause of Cygnus'
                  failure to meet Minimums. This Section shall not be construed
                  to prevent CMI from recovering monetary damages on account of
                  other breaches of this contract by Cygnus.


7.        SUPPLY SPECIFIC EQUIPMENT

                  installation at, CMI's Premises and the use of the Equipment
                  shall be restricted solely to CMI unless Cygnus instructs
                  otherwise in writing. CMI will use and operate the Equipment
                  in a careful manner, will comply with all governmental laws
                  and regulations related thereto, and will cause the Equipment
                  to be operated in accordance with the applicable operating
                  manuals. CMI will not make or authorize any change to the
                  Equipment without the prior written consent of Cygnus. CMI
                  shall only permit the Equipment to be operated by competent
                  and qualified employees and shall ensure that the Equipment is
                  not subject to careless or rough usage. The Equipment will not
                  be moved from CMI's Premises without Cygnus' prior written
                  consent.

         7.5.     REMOVAL OF EQUIPMENT. At the end of the Term or following any
                  termination, CMI shall provide Cygnus with reasonable access
                  to its facilities, as Cygnus requires, to remove all Equipment
                  from CMI's facilities. Cygnus shall have responsibility for
                  any damage to CMI's facility arising from the removal of such
                  Equipment.

         7.6.     TAXES; PERMITS; FEES. CMI shall secure any and all necessary
                  governmental or regulatory approvals or permits required by
                  any law or regulation for the possession or operation of the
                  Equipment. Cygnus is solely responsible for the payment of any
                  and all required taxes or governmental fees incurred with
                  respect to the Equipment during the Term. If any change is
                  required in the Equipment during the bailment term to bring
                  the Equipment into compliance with any new law or regulation
                  applicable to the Equipment, CMI shall be responsible for
                  implementing and Cygnus shall pay for the change required to
                  make the Equipment comply with such requirements. CMI shall
                  secure and pay for any necessary governmental or regulatory
                  approvals or permits required by any law or regulation for the
                  operation or maintenance of CMI's Premises. Taxes, Permits and
                  Fees relating to the operation and maintenance of CMI's

         7.7.     NO WARRANTY, NO LIABILITY FOR EQUIPMENT. THE PARTIES HERETO
                  AGREE THAT THE EQUIPMENT IS LOANED WITHOUT ANY EXPRESS OR
                  IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED
                  WARRANTIES OF MERCHANTABILITY, NONINFRINGEMENT AND FITNESS FOR
                  A PARTICULAR PURPOSE. Cygnus shall not be liable for any loss
                  or damage, including third party losses or claims, claimed to

                  installation, warning, possession, or use of the Equipment
                  regardless of the form of action, including, but not limited
                  to, those claims based upon strict liability or negligence.
                  Cygnus shall not be liable for loss of profit or other
                  consequential damages resulting from the theft, destruction,
                  breakdown, or disrepair of the Equipment or for the failure of
                  the Equipment to operate properly.

         7.8.     INSURANCE. During the Term, CMI shall maintain casualty, fire,
                  and theft insurance on the

<PAGE>

                  Equipment in amounts deemed appropriate by Cygnus. The
                  proceeds of any such insurance coverage with respect to the
                  Equipment shall be payable solely to Cygnus. CMI, at its own
                  expense, shall obtain such additional insurance coverage on
                  the Equipment or on CMI's Premises as CMI shall require. Upon
                  Cygnus' request, CMI shall deliver copies of the policies and
                  loss payable endorsements (in form satisfactory to Cygnus) to
                  Cygnus.


8.       RAW MATERIALS.

         8.1.     Cygnus will negotiate agreements with suppliers of Cygnus'
                  choice for supply of Glucopad material (supplied in rolls) and
                  biosensors ( materials to be used in the manufacture of
                  Consumer Package Units ). Cygnus will provide CMI with a copy
                  of the relevant supply agreements ("Master Supply
                  Agreements"). CMI shall issue its own purchase orders directly
                  to such suppliers, with a copy to Cygnus, and will reference
                  the applicable Master Supply Agreements for terms and pricing.

         8.2.     For any such materials that are purchased to enable CMI to
                  fill firm orders, Cygnus shall pay CMI at least ten (10) days
                  prior to the date upon which CMI must pay the supplier for
                  such materials. If CMI acquires inventory in excess of the
                  materials needed for firm orders it shall bear sole
                  responsibility and risk with respect to such inventory,
                  including without limitation the risk that such inventory
                  could become obsolete. However, this paragraph shall not apply
                  to the extent that such excess material obtained by CMI is
                  pursuant to minimum requirements defined in a Master Supply
                  Agreement. CMI shall be solely responsible for any
                  transportation charges pertaining to the return and reshipping
                  of any rejected materials.

9.       WARRANTY; INDEMNITY.

         9.1.     CMI warrants (i) Consumer Package Units, when shipped to
                  Cygnus, shall conform to the then in effect Specifications as
                  determined under Section 3; (ii) Consumer Package Units, when
                  shipped to Cygnus, shall conform with the information on the

                  in conformance with all applicable Good Manufacturing
                  Practices which are in force or hereinafter adopted by the FDA
                  or any successor agency thereto; (iv) Consumer Package Units
                  shall not have been adultered; and (v) title to all Consumer
                  Package Units shall be free of any security interest or
                  encumbrance. CMI makes no warranty, expressed or implied, with
                  respect to material supplied by vendors under the Master
                  Supply Agreements including the warranty of merchantability.

         9.2.     CMI agrees to defend Cygnus from, indemnify Cygnus and hold
                  Cygnus harmless from any claim, demand, action, cause of
                  action or suit (each a "Claim") related to or arising from any

                  cause of action arising from a defect in a Consumer Package
                  Unit, where such Consumer Package Unit, as supplied, was in
                  full conformance with the warranty set forth in Section 9.1.
                  CMI also agrees to defend Cygnus from, indemnify Cygnus and
                  hold Cygnus harmless from any Claim arising out of or
                  resulting from any injury to any person or damage to any
                  property caused by the Supply Specific Equipment as a result
                  of the testing , installation, insufficiency of any warnings
                  thereon or of CMI's improper use of the Equipment. In the
                  event Cygnus is served or is otherwise notified of any Claim
                  under this Section 9.2, it shall notify CMI thereof and tender
                  its defense to CMI who shall promptly undertake such defense
                  with counsel mutually acceptable to both parties. Either party
                  receiving an offer of settlement shall communicate such offer
                  as soon as reasonably practicable to the other. In the event
                  Cygnus enters into a settlement, without the prior consent of
                  CMI, it will be deemed to

                                       7
<PAGE>

                  have waived its right under this Section to be indemnified
                  from any amounts it becomes obligated to pay under the terms
                  of the settlement agreement.


10.      PATENT/INTELLECTUAL PROPERTY INDEMNITY.

         10.1.    CMI agrees to defend Cygnus from, indemnify Cygnus and hold
                  Cygnus harmless from any claim, demand, action, cause of
                  action or suit related to or arising from any claim that the
                  manufacturing processes used to produce Consumer Package Units
                  (apart from the materials supplied by Cygnus) supplied by CMI
                  infringe any patent or intellectual property right held by a
                  third party. In the event Cygnus is served or is otherwise
                  notified of any such claim, it shall notify CMI thereof and
                  tender its defense to CMI who shall promptly undertake such
                  defense with counsel mutually acceptable to both parties.
                  Either party receiving an offer of settlement shall
                  communicate such offer as soon as reasonably practicable to
                  the other. In the event Cygnus enters into a settlement,
                  without the prior consent of CMI, it shall be deemed to have
                  waived its right under this Section to be indemnified from any
                  amounts it becomes obligated to pay under the terms of such
                  settlement agreement.


11.      SECONDARY FACILITIES.

         11.1.    The parties agree that Cygnus may establish one or more of its
                  own facilities ("Secondary Facilities") to produce Consumer

                  having made and marketing Consumer Package Units and
                  components thereof. For the purposes of this Section 11, "CMI
                  Technology" shall mean any invention (whether or not
                  patentable), idea, process, formula, know-how and/or software
                  owned, licensed or controlled by CMI during the term of this
                  Agreement, that is or will be necessary or useful to Cygnus in
                  the production of Consumer Package Units or components
                  thereof.

                  to Cygnus, CMI shall, as requested from time to time by
                  Cygnus, disclose to Cygnus in tangible form the CMI
                  Technology. To carry out the transfer of CMI Technology that
                  cannot be provided in tangible form (for instance, certain
                  "know-how"), CMI shall, as soon as reasonably practicable
                  after a request from Cygnus from time to time, disclose such
                  CMI Technology to employees and contractors of Cygnus through
                  consultation at Cygnus' Secondary Facilities. In connection
                  with such technology transfer, Cygnus shall compensate CMI for
                  time of its employees and for the reasonable direct costs of
                  travel to the Secondary Facilities, as approved in advance by
                  Cygnus.

                  owner of the intellectual property rights in any invention of
                  which only its employees and its third party contractors are
                  inventors and each party will jointly own the intellectual
                  property rights in all inventions of which both parties'
                  employees or contractors are joint inventors, except that
                  intellectual property rights with respect to inventions which
                  claim or relate in any way to (i) [CONFIDENTIAL TREATMENT
                  REQUESTED], (ii) [CONFIDENTIAL TREATMENT REQUESTED], (iii)
                  [CONFIDENTIAL TREATMENT REQUESTED], (iii) [CONFIDENTIAL
                  TREATMENT REQUESTED], (iv) [CONFIDENTIAL TREATMENT REQUESTED],
                  will be solely owned by Cygnus. Any assignments necessary to
                  accomplish the foregoing are hereby made and each party will
                  execute such further documents as may be reasonably requested
                  by the other with respect thereto.

                  party ("Proprietary Information" of the disclosing party).
                  Except as expressly allowed in this Agreement, the receiving
                  party will hold in confidence and not use or disclose any
                  Proprietary Information of the disclosing party during the
                  term of this Agreement and for a period of five (5) years
                  after the end of the Supply Terms of this Agreement, and its
                  employees shall be similarly bound. The receiving party shall
                  not be obligated under this Section with respect to any
                  information the receiving party can document:

                                    a)  Is or has become readily publicly

                                        agents; or

                                    b)  Is received from a third party lawfully
                                        in possession of such information and
                                        lawfully empowered to disclose such
                                        information and provided the receiving
                                        party abides by all restrictions, if
                                        any, imposed by such third party; or

                                    c)  Was rightfully in the possession of the
                                        receiving party prior to its disclosure

                                        receiving party abides by all
                                        restrictions, if any, imposed on its
                                        possession of such information; or

                                    d)  Was independently developed by
                                        employees or consultants of the
                                        receiving party without use of or
                                        access to Proprietary Information of
                                        the disclosing party; or

                                    e)  Is required to be disclosed to a
                                        governmental entity or agency in
                                        connection with seeking any
                                        governmental or regulatory
                                        registration, approval or license, or
                                        pursuant to the lawful requirement or
                                        request of a governmental entity or
                                        agency, provided that reasonable
                                        measures are taken to obtain
                                        confidential treatment thereof and to
                                        guard against further disclosure.

         12.3.    Nothing in Section 12.1 or 12.2 shall prevent Cygnus from
                  utilizing in the manufacture by Cygnus itself or with a
                  third-party of Consumer Package Units or any other product
                  using Proprietary Information which Cygnus learned, received
                  or otherwise acquired from CMI.


13.      RECORDS AND AUDIT RIGHT. Both parties shall keep complete and accurate
         books and records reflecting all information necessary or useful in
         verifying the accuracy of any payment made hereunder. Each party shall
         have the right to hire an independent certified public accountant to
         inspect all such records so required to be kept by the other (which
         accountant shall agree in writing to keep all information confidential
         except as needed to disclose any discovered discrepancies); provided,
         such audit (i) is conducted during normal business hours, (ii) is
         conducted no more often than once per year (unless a discrepancy
         greater than seven percent (7%) is discovered in favor of the auditing
         party), and (iii) is conducted only after the auditing party has given
         ten (10) days prior written notice to the audited party. The auditing
         party shall bear the full cost and expense of such audit. Regardless of
         the amount of discrepancy discovered, all discrepancies (and interest
         thereon) shall be immediately due and payable by the party found to
         have caused the discrepancy. All books and records relating to either
         party's obligations under this Agreement shall be retained by such
         party for five years after the Term has expired.

                  by a party immediately upon the

                           the manner contemplated by this Agreement, or if any
                           such license, registration, permit, authorization or
                           approval is revoked or suspended and not reinstated
                           within sixty (60) days or if reinstatement is not
                           possible within sixty (60) days, or if diligent
                           efforts are not being made to effect such
                           reinstatement;

                  14.1.3.  If the other materially breaches any material
                           provision of this Agreement and fails to cure such
                           breach within sixty (60) days (except immediately in
                           the case of a breach of Section 12.2) of written
                           notice describing the breach; or

                  14.1.4.  If the other shall seek protection under any
                           bankruptcy, receivership, trust deed, creditors
                           arrangement, composition or comparable proceeding, or
                           if any such proceeding is instituted against the
                           other (and not dismissed within one hundred and
                           twenty (120) days).

         14.2.    NO LIABILITY FOR TERMINATION. Neither party shall incur any
                  liability whatsoever for any damage, loss or expenses of any
                  kind suffered or incurred by the other (or for any
                  compensation to the other) arising from or incident to any
                  termination of this Agreement by such party which complies
                  with the terms of this Agreement, whether or not such party is
                  aware of any such damage, loss or expenses.

         14.3.    EFFECT OF TERMINATION. In addition to provisions that by their
                  terms survive termination, the following provisions shall
                  survive the termination of this Agreement: Sections 4.4, 7,
                  8.2, 9, 10, 12, 13 and 15. Remedies for all breaches hereunder
                  will also survive. Each party will promptly return all
                  Proprietary Information of the other (and all copies and
                  abstracts thereof, except that one (I) copy may be retained
                  and shall be kept in its legal archives for legal record
                  keeping purposes only) that it is not entitled to under the
                  surviving terms of this Agreement.

         14.4.    TERMINATION NOT SOLE REMEDY. Termination is not the sole
                  remedy under this Agreement and, whether or not termination is
                  effected, all other remedies will remain available.


15.      GENERAL.

         15.1.    AMENDMENT AND WAIVER. Except as otherwise expressly provided
                  herein, any provision of this Agreement may be amended and the
                  observance of any provision of this Agreement may be waived
                  (either generally or in any particular instance and either
                  retroactively or prospectively) only with the written consent
                  of the parties. However, it is the intention of the parties
                  that this Agreement be controlling over additional or
                  different terms of any purchase order, confirmation, invoice
                  or similar document, even if accepted in writing by both
                  parties, and that waivers and amendments of any provision of
                  this Agreement shall be effective only if made by
                  non-pre-printed agreements signed by both parties and clearly
                  understood by both parties to be an amendment or waiver. The
                  failure of either party to enforce its rights under this
                  Agreement at any time for any period shall not be construed as
                  a waiver of such rights.

                  governed by and construed under the laws of the State of

                  of laws provisions thereof and without regard to the United
                  Nations Convention on Contracts for the International Sale of
                  Goods. The sole jurisdiction and venue for actions related to
                  the subject matter hereof

                  Francisco, California. Both parties consent to the
                  jurisdiction of such courts and agree that process may be
                  served in the manner provided herein for giving of notices or
                  otherwise as allowed U.S. federal law or the laws of
                  California. In any action or proceeding to enforce rights
                  under this Agreement, the prevailing party shall be entitled
                  to recover costs and attorney's fees.

         15.5.    ENTIRE AGREEMENT. This Agreement (and all Exhibits hereto)
                  constitutes the entire understanding and agreement with
                  respect to the subject matter hereof and supersedes all
                  proposals, oral or written, all negotiations, conversations,
                  or discussions between or among parties relating to the
                  subject matter of this Agreement and all past dealing or
                  industry custom.

         15.6.    SEVERABILITY. If any provision of this Agreement is held to be
                  illegal or unenforceable, that provision shall be limited or
                  eliminated to the minimum extent necessary so that this
                  Agreement shall otherwise remain in full force and effect and
                  enforceable.

         15.7.    BASIS OF BARGAIN. Each party recognizes and agrees that the
                  warranty disclaimers and liability and remedy limitations in
                  this Agreement are material bargained for bases of this
                  Agreement and that they have been taken into account and
                  reflected in determining the consideration to be given by each
                  party under this Agreement and in the decision by each party
                  to enter into this Agreement.

         15.8.    RELATIONSHIP OF PARTIES. The parties hereto expressly
                  understand and agree that the other is an independent
                  contractor in the performance of each and every part of this
                  Agreement and is solely responsible for all of its employees
                  and agents and its labor costs and expenses arising in
                  connection therewith.

         15.9.    ASSIGNMENT. This Agreement and the rights and obligations
                  hereunder are not transferable or assignable by either party
                  without the prior written consent of the other party, except
                  for rights to

                                       11
<PAGE>

                  payment and except to a person or entity who acquires all or
                  substantially all of a party's stock, assets or business to
                  which this Agreement pertains, whether by sale, merger,
                  acquisition or otherwise.

         15.10.   PUBLICITY AND PRESS RELEASES. Except to the extent necessary
                  under applicable laws or for ordinary marketing purposes, the
                  parties agree that no press releases or other publicity
                  relating to the substance of the matters contained herein will
                  be made without approval by both parties. A press release
                  announcing this Agreement will be jointly developed and
                  released by the parties.

         15.11.   FORCE MAJEURE. No liability or loss of rights hereunder shall
                  result to either party from delay or failure in performance
                  caused by an event of force majeure (that is, circumstances
                  beyond the reasonable control of the party affected thereby,
                  including, without limitation, acts of God, fire, flood, war,
                  government action, strikes, lockouts or other serious labor
                  disputes and vendors inability to supply material due to such
                  events.) for so long as such event of force majeure continues
                  in effect.

         15.12.   REMEDIES. Except as otherwise expressly stated in this
                  Agreement, the rights and remedies of a party set forth herein
                  with respect to failure of the other to comply with the terms
                  of this Agreement (including, without limitation, rights of
                  full termination of this Agreement) are not exclusive, the
                  exercise thereof shall not constitute an election of remedies
                  and the aggrieved party shall in all events be entitled to
                  seek whatever additional remedies may be available in law or
                  in equity.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the
Effective Date.

                                SUPPLY AGREEMENT

This Supply Agreement ("Agreement") is entered as of December 1, 1999
("Effective Date") by and between Cygnus, Inc., a Delaware corporation, with its
principal place of business at 400 Penobscot Drive, Redwood City, California
94063 ("Cygnus"), and Key Tronic Corporation., a Washington corporation, with
its principal place of business at N. 4424 Sullivan Road, Spokane, Washington
99216 ("Key Tronic").

1.       SCOPE OF AGREEMENT

A.       This Agreement shall cover the purchase by Cygnus and the sale by Key
Tronic of one or more of the products identified in Exhibit A (the "Product"),
attached to this Agreement. Key Tronic agrees to manufacture the Product in
accordance with Cygnus' specifications and drawings set forth in Exhibit B (the
"Specifications"), attached to this Agreement. Exhibit B may be amended from
time to time by mutual written agreement of the parties. Key Tronic acknowledges
that (i) time is of the essence in the delivery of the Product and (ii) Product
quality is of critical importance to Cygnus. Failure of Key Tronic to supply
Product as specified shall be grounds for termination of this Agreement by

                (3) days after receipt of an order, a firm shipment schedule and
                an order acknowledgment. All orders shall be subject to
                acceptance by HDS at its headquarters. HDS shall accept Cygnus',
                its Affiliates' or subcontractors' purchase orders to the extent
                that the purchase orders are in accordance with the most recent
                non-binding quarterly forecast acknowledged by HDS pursuant to
                Section 2(c) above. HDS shall accept purchase orders otherwise
                in accordance with the provisions of this Agreement, provided
                such purchase orders are for quantities of Hydrogel Laminate
                which are not more or less than [CONFIDENTIAL TREATMENT
                REQUESTED] of the most recent acknowledged non-binding quarterly

                use reasonable efforts to accommodate cancellations or
                modifications within three (3) weeks of shipment. Any
                cancellation or extension permitted hereunder which, if accepted
                by HDS, would result in any charge or cost associated with Raw
                Materials shall be the sole responsibility of Cygnus. HDS
                reserves the right to use any Raw Materials rendered surplus
                pursuant to the terms of this Section 2(d).

        i.      Pricing for units of Hydrogel Laminate sold to Cygnus is set
                forth in Exhibit B and shall remain fixed for the term of this
                agreement subject to changes in raw material costs as follows.
                In the event that raw material costs change by [CONFIDENTIAL
                TREATMENT REQUESTED] or more (either an increase or decrease)
                from the cost identified on the Effective Date, HDS will adjust
                the pricing by the amount of such cost change. Such price
                changes will occur no more than once per three (3) month period
                and shall be documented in writing by HDS. Raw material cost
                changes of less than [CONFIDENTIAL TREATMENT REQUESTED] (either
                an increase or decrease) shall be absorbed by HDS.

                All prices are exclusive of any sales, use or other applicable
                taxes, which shall be paid or reimbursed by Cygnus, its
                Affiliates or subcontractors. If Cygnus claims such sales are
                exempt from such taxes, then Cygnus, its Affiliates or
                subcontractors shall furnish HDS with satisfactory evidence of
                such exemption from such taxes.

        ii.     Payment terms will be net thirty (30) days after delivery of a
                shipper's bill of lading to Cygnus for a shipment of Hydrogel
                Laminate. HDS reserves the right to charge interest on overdue
                balances in the amount of [CONFIDENTIAL TREATMENT REQUESTED] per
                month.

        iii.    All Hydrogel Laminate is to be shipped F.O.B. HDS' Facility,
                Langhorne, Pennsylvania, freight pre-paid and billed. Risk of
                loss shall pass at the F.O.B. point.

         f.       CONFLICTING TERMS. In ordering and delivering Hydrogel
Laminate, HDS and its Affiliates and Cygnus, its Affiliates and subcontractors
may use their standard forms, however, nothing in such forms shall be construed
to amend or modify the terms of this Agreement. If Cygnus', its Affiliates' or
subcontractors' purchase order forms or HDS' order acknowledgement forms contain
terms that contradict or vary any terms contained in this Agreement, then the
terms of this Agreement shall prevail and control.

         g.       ACCEPTANCE PROCEDURES. Cygnus, its Affiliates or
subcontractors, shall inspect the Hydrogel Laminate within twenty (20) days of
its receipt. If Cygnus finds that the Hydrogel Laminate has a defect ("Defect"
meaning that such Hydrogel Laminate fails to conform to the applicable
Specifications or otherwise fail to conform to the warranties given by HDS under
this


                                       5

Agreement), Cygnus will notify HDS in writing. HDS agrees to promptly
investigate such reported defect and promptly provide to Cygnus, in writing the
findings of their investigation. If it is found that HDS is responsible for the
reported defect, HDS agrees to remedy such reported defect by supplying
replacement Hydrogel Laminate within a reasonable time period. If HDS fails to
remedy such reported defects within two months from the date of receipt of such
a report, then HDS agrees to issue a credit for the face amount of the affected
purchase order.

         h.       EXCLUSIVITY. During the term of this Agreement, HDS shall not
develop, manufacture, produce, or supply to any third parties any Hydrogel
Laminate. HDS shall not assign or delegate all or any portion of its obligations
under the terms of this Agreement without prior written consent of Cygnus at
Cygnus' sole discretion. HDS shall at all times remain fully responsible for all
obligations and commitments hereunder.

fault of the receiving Party or its employees or agents; or

                  b. is received from a third party lawfully in possession of
such information and lawfully empowered to disclose such information and
provided the receiving Party abides by all restrictions, if any, imposed by such
third party; or

                  c. was rightfully in the possession of the receiving Party
prior to its disclosure by the other Party as shown by the receiving Party's
written records provided the receiving Party abides by all restrictions, if any,
imposed on its possession of such information; or
                  d. was independently developed by employees or consultants of
the receiving Party as shown by the receiving Party's written records without
use of or access to Proprietary Information of the disclosing Party.

          The Licensee entered into a Secrecy Agreement (U.C. Control NO.
88-20-0315) with The Regents, effective December 14, 1988, and terminating on
December 14, 1993, for the purpose of evaluating the Invention.

          The Licensee entered into an Option Agreement (U.C. Control No.
90-11-0352) with The Regents, effective August 29, 1990, and terminating on
September 30, 1994, for the purpose of evaluating the Invention.

          The Licensee is a "small business firm" as defined in 15 U.S.C. 632.

          The Licensee is desirous of obtaining certain exclusive rights from

funding to support the development


                                       6
<PAGE>

of a monitor/delivery device for the [CONFIDENTIAL TREATMENT REQUESTED], the
Licensee shall have [CONFIDENTIAL TREATMENT REQUESTED]from the date of
notification from The Regents identifying [CONFIDENTIAL TREATMENT REQUESTED]
to commit sufficient research support to The Regents for such development,
and the Licensee agrees to negotiate with The Regents a development and
regulatory timetable similar to that in Section 6.4 above. If the Licensee
declines to commit to support and to diligently develop the Invention for the
identified sampling[CONFIDENTIAL TREATMENT REQUESTED], The Regents shall have
the right to terminate this license with regard to the

supersedes the rights granted in Article 2 (GRANT). If The Regents terminates
this Agreement with respect to such [CONFIDENTIAL TREATMENT REQUESTED]and
does not license such [CONFIDENTIAL TREATMENT REQUESTED]to a third party, The
Licensee's right to commit sufficient reasonable research support to The
Regents for the development of such [CONFIDENTIAL TREATMENT REQUESTED] in
order to maintain such [CONFIDENTIAL TREATMENT REQUESTED] in the license
granted to the Licensee under this Agreement shall automatically be

                         7. PROGRESS AND ROYALTY REPORTS

          7.1 Beginning February 28, 1995, and [CONFIDENTIAL TREATMENT
REQUESTED]thereafter, the Licensee shall submit to The Regents a progress report
covering the Licensee's activities related to the development and testing of all
Licensed Products and the obtaining of the governmental approvals necessary for
marketing. These progress reports shall be made for each Licensed Product until
the first commercial sale of that Licensed Product occurs in the United States.

          7.2 The progress reports submitted under Section 7.1 should include,
but not be limited to, the following topics:

     -    summary of work completed

     -    key scientific discoveries

     -    summary of work in progress


                                       7

<PAGE>

     -    current nonbinding, good- faith schedule of anticipated events or
          milestones

     -    market plans for introduction of Licensed Products, and

     -    a summary of resources (dollar value) spent in connection with the
          Licensed Product during the reporting period.

          7.3 The Licensee shall have a continuing responsibility to keep The
Regents informed of the large/small entity status (as defined by the United
States Patent and Trademark Office) of itself and its Sublicensees.

          7.4 The Licensee also agrees to report to The Regents in its
immediately subsequent progress and royalty report the date of first commercial
sale of a Licensed Product in each country.

          7.5 After the first commercial sale of a Licensed Product anywhere in
the world, the Licensee will provide The Regents with quarterly royalty reports
on or before each February 28, May 31, August 31, and November 30 of each year.
Each such royalty report will cover the Licensee's most recently completed
calendar quarter and will show: (a) the gross sales and Net Sales of Licensed
Products sold by the Licensee during the most recently completed calendar
quarter, (b) the number of each type of Licensed Product sold by the Licensee
during the most recently completed calendar quarter, (c) the royalties, in U.S.
dollars, payable hereunder with respect to such Net Sales of Licensed Products,
(d) the method used to calculate the royalty, and (e) the exchange rates used,
if any.

          7.6 If no sales of Licensed Products have been made during any
reporting period after the first commercial sale of Licensed Products, a
statement to this effect shall be required.

                              8. BOOKS AND RECORDS

          8.1 The Licensee shall keep books and records accurately showing all
Licensed Products manufactured, used, and/or sold under the terms of this
Agreement (for the purposes of showing the amount of royalties payable to The
Regents and the Licensee's compliance with the other provisions under this
Agreement). Such books and records shall be preserved for at least five (5)
years from the date of the royalty payment to which they pertain and shall be
open to


                                       8

<PAGE>

inspection and audit only by an independent certified public accountant retained
by The Regents at reasonable times during normal business hours, upon reasonable
notice. Subject to the California Public Records Act, such independent certified
public accountant shall be bound to hold all information in confidence except as
necessary to communicate the Licensee's non-compliance with this Agreement to
The Regents. The purpose of any inspection and audit pursuant to this Paragraph
8.1 shall be to verify the Licensee's royalty statements or compliance in other
respects with this Agreement.

          8.2 The fees and expenses of The Regents' independent certified public
accountant performing such an examination shall be borne by The Regents.
However, if an error in royalties of more than [CONFIDENTIAL TREATMENT
REQUESTED] of the total royalties due for any year is discovered, then the fees
and expenses of these independent certified public accountant shall be borne by
the Licensee.

                            9. LIFE OF THE AGREEMENT

          9.1 Unless otherwise terminated by operation of law or by acts of the
parties in accordance with the terms of this Agreement, this Agreement shall be
in force from the Effective Date recited on page one and shall remain in effect
for the life of the last-to-expire patent licensed under this Agreement.

          9.2 Any termination of this Agreement shall not affect the rights and
obligations set forth in the following Articles:

               Paragraph 3.2 Sublicenses
               Article 8             Books and Records

                         10. TERMINATION BY THE REGENTS

          10.1 If the Licensee should violate or fail to perform any material
term or covenant of this Agreement, then The Regents may give written notice
of such default (Notice of Default) to the Licensee. If the Licensee should
fail to repair such default within [CONFIDENTIAL TREATMENT REQUESTED]of the
effective date of such notice, The Regents shall have the right to terminate
this Agreement and the licenses herein by a second written notice (Notice of
Termination) to the Licensee. If a Notice of Termination is sent to the
Licensee, this Agreement shall automatically terminate on the effective date
of such notice. Such termination shall not relieve the Licensee of its
obligation to pay any royalty or license issue fees owing at the time of such
termination and shall not impair any accrued right of The Regents. These
notices shall be subject to Article 19 (Notices).

                         11. TERMINATION BY THE LICENSEE

          11.1 The Licensee shall have the right at any time to terminate this
Agreement in whole or as to any portion of Regents' Patent Rights by giving
notice in writing to The Regents. Such notice of termination shall be subject to
Article 19 (Notices), and termination of this Agreement shall be effective
[CONFIDENTIAL TREATMENT REQUESTED]from the effective date of such notice. If
such termination is without cause within the [CONFIDENTIAL TREATMENT
REQUESTED]of this Agreement, Licensee shall pay The Regents [CONFIDENTIAL
TREATMENT REQUESTED] ("[CONFIDENTIAL TREATMENT REQUESTED]") with the notice of
termination before such notice is effective, except that if the Licensee can
provide The Regents with written evidence satisfactory to The Regents that there
is good cause for termination of this Agreement by the Licensee, such as, for
example and without limitation, the refusal of the FDA to grant regulatory
approval of a Licensed Product or the inability of the Licensee to overcome
technical obstacles in the commercialization of a Licensed Product, then the
Licensee will not be required to pay the Relicense Fee.


                                       10

<PAGE>

          11.2 Any termination pursuant to the above Paragraph 11.1 shall not
relieve the Licensee of any obligation or liability accrued hereunder prior to
such termination or rescind anything done by the Licensee or any payments made
to The Regents hereunder prior to the time such termination becomes effective,
and such termination shall not affect in any manner any rights of The Regents
arising under this Agreement prior to such termination.

          12. DISPOSITION OF LICENSED PRODUCTS ON HAND UPON TERMINATION

          12.1 Upon termination of this Agreement, the Licensee shall have the
privilege of disposing of all previously made or partially made Licensed
Products, but no more, within a period of one hundred and twenty (120) days
following the effective date of termination, provided, however, that the sale of
such Licensed Products shall be subject to the terms of this Agreement
including, but not limited to, the payment of royalties at the rate and at the
time provided herein and the rendering of reports thereon.

           13. USE OF NAMES, TRADEMARKS, AND CONFIDENTIAL INFORMATION

          13.1 Nothing contained in this Agreement shall be construed as
conferring any right to use in advertising, publicity, or other promotional
activities any name, trade name, trademark, or other designation of either party
hereto (including any contraction, abbreviation, or simulation of any of the
foregoing). Unless required by law or consented to in writing by The Regents,
the use by the Licensee of the name "The Regents of the University of
California" or the use by the Licensee of the name of any campus of the
University of California is expressly prohibited.

          13.2 It is understood that The Regents shall be free to release to the
Inventors and senior administrative officials employed by The Regents the terms
and conditions of this Agreement upon their request. If such release is made,
The Regents shall request that such terms and conditions not be disclosed to
others. It is further understood that should a third party inquire whether a
license to Regents' Patent Rights is available, The Regents may disclose the
existence of this Agreement and the extent of the grant in Article 2 (GRANT) to
such third party, but shall not disclose the name of the


                                       11

<PAGE>

Licensee except where The Regents is required to release such information under
either the California Public Records Act or other applicable law.

                              14. LIMITED WARRANTY

          14.1 The Regents warrants to the Licensee that it has the lawful right
to grant this license.

          14.2 This license and the associated Invention are provided WITHOUT
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR ANY OTHER
WARRANTY, EXPRESS OR IMPLIED. THE REGENTS MAKES NO REPRESENTATION OR WARRANTY
THAT THE LICENSED PRODUCTS OR LICENSED METHODS WILL NOT INFRINGE ANY PATENT OR
OTHER PROPRIETARY RIGHT.

          14.3 IN NO EVENT WILL THE REGENTS BE LIABLE FOR ANY INCIDENTAL,
SPECIAL, OR CONSEQUENTIAL DAMAGES RESULTING FROM EXERCISE OF THIS LICENSE OR THE
USE OF THE INVENTION OR LICENSED PRODUCTS.

          14.4 Nothing in this Agreement shall be construed as:

          (14.4.1)  a warranty or representation by The Regents as to the
                    validity or scope of any Regents' Patent Rights; or

          (14.4.2)  a warranty or representation that anything made, used, sold,
                    or otherwise disposed of under any license granted in this
                    Agreement is or will be free from infringement of patents of
                    third parties; or

          (14.4.3)  an obligation to bring or prosecute actions or suits against
                    third parties for patent infringement except as provided in
                    Article 17; or

          (14.4.4)  conferring by implication, estoppel, or otherwise any
                    license or rights under any patents of The Regents other
                    than Regents' Patent Rights as defined herein, regardless of
                    whether such patents are dominant or subordinate to Regent's
                    Patent Rights; or

          (14.4.5)  an obligation to furnish any know-how not provided in
                    Regents' Patent Rights.

<PAGE>

                     15. PATENT PROSECUTION AND MAINTENANCE

          15.1 The Regents shall diligently prosecute and maintain the United
States patents comprising Regents' Patent Rights using counsel of its choice. If
both The Regents and the Licensee are not reasonably satisfied with such
counsel, The Regents shall replace such counsel with new counsel reasonably
acceptable to both parties. If the Licensee rejects The Regents' choice of new
counsel three times consecutively (i.e., three different new attorneys) then The
Regents shall be free, in its sole discretion, to appoint an attorney of its
choice. The Regents' counsel will take instructions only from The Regents unless
otherwise expressly authorized in writing by The Regents. The Regents shall
promptly provide the Licensee with copies of all relevant documentation so that
the Licensee may be currently and promptly informed and apprised of the
continuing prosecution. The Licensee may comment upon such documentation,
provided that if the Licensee has not commented upon such documentation prior to
the initial deadline for filing a response with the relevant government patent
office, The Regents shall be free to respond appropriately without consideration
of the Licensee's comments. The Licensee agrees to keep this documentation
confidential in accordance with the provisions of Article 28 (CONFIDENTIALITY).

          15.2 The Regents shall use all reasonable efforts to prepare or amend
any patent application to include claims reasonably requested by the Licensee to
protect the Licensed Products contemplated to be sold or Licensed Methods or
procedures to be practiced under this Agreement.

          15.3 The Regents shall cooperate with the Licensee in applying for an
extension of the term of any patent included within Regents' Patent Rights if
appropriate under the Drug Price Competition and Patent Term Restoration Act of
1984. The Licensee shall prepare all such documents, and The Regents agrees to
execute such documents and to take such additional action as the Licensee may
reasonably request in connection therewith.

          15.4 Subject to Paragraph 15.7 the costs of preparing, filing,
prosecuting, and maintaining all United States patent


                                       13

<PAGE>

applications and/or patents contemplated by this Agreement and not paid for by a
third party shall be borne by Licensee so long as the licenses granted to the
Licensee herein are exclusive. If The Regents reduces the exclusive licenses
granted herein to nonexclusive licenses pursuant to Paragraphs 6.4 or 6.6 and
The Regents grants additional licenses, the costs of filing, prosecuting, and
maintaining the patents and patent applications in Regents Patent Rights shall
be divided equally among the licensed parties from the effective date of each
subsequently granted license agreement. The obligations set forth in this
Paragraph 15.4 includes patent prosecution costs for this Invention incurred by
The Regents prior to the execution of this Agreement. Current and future costs
for patent prosecution and maintenance as provided herein will be billed to the
Licensee by The Regents as incurred, and the Licensee shall reimburse The
Regents for such costs within thirty (30) days of the Licensee's receipt of an
invoice from The Regents.

          15.5 The Regents shall, at the request of the Licensee, file,
prosecute, and maintain patent applications and patents covered by Regents'
Patent Rights in foreign countries if available. The Licensee must notify The
Regents within seven (7) months of the filing of the corresponding United States
patent application of its decision to request The Regents to file foreign
counterpart patent applications. This notice concerning foreign filing shall be
in writing, must identify the countries desired, and shall reaffirm the
Licensee's obligation to underwrite the costs thereof subject to the conditions
set forth in Paragraph 15.4 above. The absence of such a notice from the
Licensee to The Regents within such seven- (7-) month period shall be considered
an election by the Licensee not to secure foreign patent rights.

          15.6 The preparation, filing, and prosecuting of all foreign patent
applications filed at the Licensee's request, as well as the maintenance of all
resulting patents, shall be at the sole expense of the Licensee subject to the
conditions set forth in Paragraph 15.4 above. Such patents shall be held in the
name of The


                                       14

<PAGE>

Regents and shall be obtained using counsel of The Regents' choice in accordance
with Section 15.1 of this Agreement.

          15.7 The Licensee's obligation to underwrite and to pay patent
prosecution and maintenance costs shall continue for so long as this Agreement
remains in effect provided, however, that the Licensee may terminate its
obligations with respect to any given patent application or patent upon one (1)
month's written notice to The Regents provided that any costs incurred by The
Regents prior to such written notice (or necessarily incurred within three (3)
months after such written notice) shall be borne by the Licensee. If The Regents
initiates any action subsequent to the written notice from the Licensee, then
The Regents shall bear all costs associated with that action. The Regents will
use its best efforts to curtail patent costs when such a notice is received from
the Licensee. Those costs which cannot be curtailed will be due and owing. The
Regents may continue prosecution and/or maintenance of such application(s) or
patent(s) at its sole discretion and expense provided, however, that the
Licensee shall have no further right or licenses thereunder unless the Licensee
pays to The Regents an amount equal to the costs the Licensee would otherwise
have been obligated to pay, and further provided that The Regents has not
granted an exclusive license to a third party in such patent and patent
applications subsequent to the Licensee's written notice. Costs of
interferences, oppositions, and appeals shall be considered prosecution costs
for the purposes of this Agreement but the Licensee may credit these costs
against future earned royalties.

          15.8 The Regents shall have the right to file patent applications at
its own expense in any country in which the Licensee has not elected to secure
patent rights, and such applications and resultant patents shall not be subject
to this Agreement unless the Licensee pays to The Regents an amount equal to the
costs the Licensee would otherwise have been obligated to pay, and further
provided that The Regents has not granted an exclusive license to a third party
in such patent and patent applications subsequent to the


                                       15

<PAGE>

Licensee's written notice of its decision not to secure such patent protection.

                               16. PATENT MARKING

          16.1 The Licensee agrees to mark all Licensed Products made, used, or
sold under the terms of this Agreement, or their containers, or packaging, in
accordance with the applicable patent marking laws.

                             17. PATENT INFRINGEMENT

          17.1 In the event that the Licensee shall learn of the substantial
infringement of any patent licensed under this Agreement, the Licensee shall
call The Regents' attention thereto in writing and shall provide The Regents
with reasonable evidence of such infringement. Both parties to this Agreement
agree that during the period and in a jurisdiction where the Licensee has
exclusive rights under this Agreement, neither will notify a third party of the
alleged infringement of any of Regents' Patent Rights without first obtaining
consent of the other party, which consent shall not be unreasonably denied. Both
parties shall use their reasonable efforts in cooperation with each other to
terminate such infringement without litigation. The Licensee shall have no
obligation, and The Regents shall have no right, to grant rights to such
infringing party in derogation of the Licensee's exclusive licenses under this
Agreement.

          17.2 The Licensee may request that The Regents take legal action
against the infringement of Regents' Patent Rights. Such request shall be made
in writing and shall include reasonable evidence of such infringement and
damages to the Licensee. If the infringing activity has not been abated within
ninety (90) days following the effective date of such request, The Regents shall
have the right to:

               a)   commence suit on its own account or

               b)   refuse to participate in such suit,

and The Regents shall give notice of its election in writing to the Licensee by
the end of the [CONFIDENTIAL TREATMENT REQUESTED]after receiving notice of such
request from the Licensee. Absent refusal


                                       16

<PAGE>

under Paragraph 17.2 (b), The Regents shall commence suit promptly thereafter,
in no event later than [CONFIDENTIAL TREATMENT REQUESTED]following such notice.
Election by The Regents to commence such suit shall be without prejudice of the
right of the Licensee to intervention on its own account under Rule 24 of the
Federal Rules of Civil Procedure, provided that before application to the court
therefor, the Licensee shall first meet with The Regents and discuss fully with
them its reasons for such intervention. The Licensee may thereafter bring suit
for patent infringement if and only if The Regents elects not to commence suit
and if the infringement occurred during the period and in a jurisdiction where
the Licensee had exclusive rights under this Agreement. However, in the event
the Licensee elects to bring suit in accordance with this paragraph, The Regents
may thereafter join such suit at its own expense. Failing such joinder: (i) as
between the Licensee and The Regents, the Licensee shall have the sole right to
prosecute such action and recover damages for infringement, including past
infringement; and (ii) The Regents acknowledges that it will be bound by the
results of such action, will refrain from duplicate litigation involving such
infringement by the infringing party and those in privity with it, will
cooperate with the Licensee at the Licensee's expense in responding to discovery
requests by the infringing party relevant to issues of patent validity and
enforceability, and upon request will submit to the court an affidavit to the
foregoing effects.

          17.3 Such legal action as is decided upon shall be at the expense of
the party on account of whom suit is brought and all recoveries recovered
thereby shall belong to such party provided, however, that legal action brought
jointly by The Regents and the Licensee, or by one such party with later
intervention or joinder by the other, and fully participated in by both shall be
at the joint expense of the parties and all recoveries from such joint legal
action shall be allocated in the following order: (i) to each party as
reimbursement of costs and fees of outside attorneys and other related expenses
to the extent each party paid for such costs, fees and expenses in proportion to
the share of expenses paid by each


                                       17

<PAGE>

party and until such costs, fees, and expenses are consumed; and (ii) any
remaining amount to be divided by the parties in the following manner: 1)
[CONFIDENTIAL TREATMENT REQUESTED] and 2) [CONFIDENTIAL TREATMENT REQUESTED]

          17.4 Each party agrees to cooperate with the other in legal
proceedings instituted hereunder but at the expense of the party on account of
whom such proceeding is brought. Such legal proceedings shall be controlled by
the party bringing the action except that The Regents may be represented by
counsel of its choice, at its expense, pursuant to The Regents' determination in
any action brought by the Licensee and the Licensee may be represented by
counsel of its choice at its sole expense in any action brought by The Regents
in which the Licensee intervenes.

                               18. INDEMNIFICATION

          18.1 The Licensee agrees to indemnify, hold harmless, and defend The
Regents, their officers, employees, and agents; the sponsors of the research
that led to the Invention; and the Inventors of any Invention covered by any of
the patents and patent applications under Regents' Patent Rights and their
employers against any and all claims, suits, losses, damage, costs, fees, and
expenses resulting from or arising out of exercise of this license or any
sublicense. This indemnification will include, but will not be limited to, any
product liability.

          18.2 The Licensee, at its sole cost and expense, shall insure its
activities in connection with the work under this Agreement, and obtain, keep in
force, and maintain Comprehensive or Commercial Form General Liability Insurance
(contractual liability included) or an equivalent program of self-insurance with
limits as follows:

     (a)  [CONFIDENTIAL TREATMENT REQUESTED]

     (b)  [CONFIDENTIAL TREATMENT REQUESTED]

     (c)  [CONFIDENTIAL TREATMENT REQUESTED]

     (d)  [CONFIDENTIAL TREATMENT REQUESTED]

     It should be expressly understood, however, that the coverages and limits
referred to under the above shall not in any way limit the liability of the
Licensee. The Licensee shall furnish The Regents


                                       18

<PAGE>

with certificates of insurance evidencing compliance with all requirements. Such
certificates shall.

          (18.2.1)          Provide a thirty (30)-day advance written
                            notice to The Regents of any modification.

          (18.2.2)          Indicate that The Regents has been endorsed
                            as an additional insured under the coverages
                            referred to under the above, but only with
                            respect to the subject matter of this
                            Agreement.

          (18.2.3)          Include a provision that the coverages will
                            be primary and will not participate with nor
                            will be excess over any valid and
                            collectable insurance or program of
                            self-insurance carried or maintained by The
                            Regents.

          18.3 The Regents shall promptly notify Licensee in writing of any
claim or suit, or any perceived written threat thereof, brought against The
Regents in respect of which The Regents intends to invoke the provisions of this
Article 18. The Licensee will keep The Regents informed on a current basis of
its defense of any claims pursuant to this Article 18. No settlement of any
claim or suit, or any perceived written threat thereof, received by The Regents
shall be made without the approval of the Licensee if indemnification is sought
by The Regents hereunder.

                                   19. NOTICES

          19.1 Any notice or payment required to be given to either party shall
be deemed to have been properly given and to be effective (a) on the date of
delivery if delivered in person or (b) five (5)days after mailing if mailed by
first-class certified mail, postage paid, to the respective addresses given
below or to such other address as it shall designate by written notice given to
the other party.

          28.1 The Regents and the Licensee respectively shall hold the other

<PAGE>

that party uses to protect its own proprietary information of a like nature for
a period from the date of disclosure until five (5) years after the date of
termination of this Agreement. All proprietary information shall be labeled or
marked confidential or as otherwise appropriate by the disclosing party. All
confidential information orally disclosed shall be reduced to writing or some
other physically tangible form, marked and labeled as set forth above by the
disclosing party and delivered to the receiving party within thirty (30) days of
the oral disclosure as a record of the disclosure and the confidential nature
thereof. Nothing contained herein shall in any way restrict or impair the right
of the Licensee or The Regents to use, disclose or otherwise deal with any
information or data that it can document:

          (28.1.1)  that the recipient can demonstrate by written records was
                    previously known to it; or

          (28.1.2)  that is now, or becomes in the future, public knowledge
                    other than through acts or omissions of the recipient; or

          (28.1.3)  that is lawfully obtained without restrictions by the
                    recipient from sources independent of the disclosing party;
                    or

          (28.1.4)  that was independently developed by the recipient by
                    employees without the use of or access to the disclosing
                    party's similar proprietary information as shown by written
                    records; or

          (28.1.5)  that is required to be disclosed to a governmental entity or
                    agency in connection with seeking any governmental or
                    regulatory approval, or pursuant to the lawful requirement
                    or request of a governmental entity or agency; or

          (28.1.6)  that is furnished to a third party by the recipient without
                    similar confidentiality restrictions imposed on such third
                    party, as evidenced in writing, or


                                       22

<PAGE>

          (28.1.7)  that The Regents is required to disclose pursuant to the
                    California Public Records Act or other applicable law.

          28.2 Upon termination of this Agreement, the Licensee and The Regents
agree to destroy or return to the disclosing party proprietary information
received from the other in its possession within fifteen (15) days following the
effective date of termination. However, each party may retain one copy of
proprietary confidential information of the other solely for archival purposes
in nonworking confidential files for the sole purpose of verifying the ownership
of the proprietary information, provided that such proprietary information shall
be subject to the confidentiality provisions set forth above in Paragraph 28.1.
Upon request, the Licensee and The Regents agree to provide each other, within
thirty (30) days following termination, with a written notice that proprietary
information has been returned or destroyed.

                29. INFRINGEMENT UNDER DRUG PRICE COMPETITION ACT

          29.1 In the event either party receives notice pertaining to any
patent included within Regents' Patent Rights pursuant to the DRUG PRICE
COMPETITION AND PATENT TERM RESTORATION ACT OF 1984 (Public Law 98-417) or
foreign equivalent legislation (hereinafter, "the Act"), including but not
necessarily limited to notices pursuant to Sections 101 and 103 of the Act from
persons who have filed an Abbreviated New Drug Application or device equivalent
("ANDA"), or a "paper" New Drug Application or device equivalent ("paper"
"NDA"), or in the case of an infringement of Regents' Patent Rights as defined
in Section 271(e) of Title 35 of the United States Code, such party shall notify
the other party promptly but in no event later than ten (10) days after receipt
of such notice.

          29.2 If the Licensee wishes action to be taken against such
infringement as provided in the Act, the Licensee shall request such action by
written notice to The Regents. Within thirty (30) days of receiving said
request, The Regents will give written notice to the Licensee of its election
to:

          (29.2.1) commence suit on its own account; or


                                       23

<PAGE>

          (29.2.2) refuse to participate in such suit. The Licensee may
thereafter bring suit for patent infringement as provided by the Act if and only
if The Regents elects not to commence suit and if the infringement occurred
during the period that the Licensee had exclusive rights in the United States
under this Agreement. However, in the event the Licensee elects to bring suit in
accordance with this paragraph, The Regents may thereafter join such suit at its
own expense.

          29.3 The provisions of paragraphs 17.3 and 17.4 shall likewise apply
to any legal action brought under this Article 29.

          29.4 The Regents hereby authorizes the Licensee to include in any NDA
for a Licensed Product a list of patents included within Regents' Patent Rights
identifying The Regents as patent owner.

                                30. MISCELLANEOUS

          30.1 The headings of the several sections are inserted for convenience
of reference only and are not intended to be a part of or to affect the meaning
or interpretation of this Agreement.

          30.2 This Agreement will not be binding upon the parties until it has
been signed below on behalf of each party; in which event, it shall be effective
as of the Effective Date recited on page one hereof.

          30.3 No amendment or modification hereof shall be valid or binding
upon the parties unless made in writing and signed on behalf of each party.

          30.4 This Agreement embodies the entire understanding of the parties
with respect to the subject matter hereof and shall supersede all previous
communications, representations, or understandings, either oral or written,
between the parties relating to the subject matter hereof. A Secrecy Agreement
between the parties dated December 14, 1988, has already expired, and the Option
Agreement dated August 29, 1990, will automatically terminate upon both parties'
execution of this Agreement.

          30.5 In case any of the provisions contained in this Agreement shall
be held to be invalid, illegal, or unenforceable in any respect, such
invalidity, illegality, or unenforceability shall



                                       24
<PAGE>

not affect any other provisions hereof, but this Agreement shall be construed as
if such invalid or illegal or unenforceable provisions had never been contained
herein.

          IN WITNESS WHEREOF, both The Regents and the Licensee have executed
this Agreement in duplicate originals by their respective officers hereunto duly
authorized, on the day and year hereinafter written.

                            1999 STOCK INCENTIVE PLAN
                      AS AMENDED AND RESTATED MARCH 1, 2000

SECTION 1. INTRODUCTION.

         The Cygnus, Inc. 1999 Stock Incentive Plan amended and restated the
Company's 1994 Stock Option/Award Plan effective February 1, 1999. Effective
March 1, 2000, the Plan was further amended and restated to increase the number
of shares available for Award by 2,000,000 shares subject to stockholder
approval.

         The purpose of the Plan is to promote the long-term success of the
Company and the creation of stockholder value by offering Key Employees an
opportunity to acquire a proprietary interest in the success of the Company, or
to increase such interest, and to encourage such selected persons to continue to
provide services to the Company or its Subsidiaries and to attract new
individuals with outstanding qualifications.

         The Plan seeks to achieve this purpose by providing for Awards in the
form of Restricted Stock, Stock Units, Options (which may constitute Incentive
Stock Options or Nonstatutory Stock Options) or Stock Appreciation Rights.

         The Plan shall be governed by, and construed in accordance with, the
laws of the State of California (except its choice-of-law provisions).
Capitalized terms shall have the meaning provided in Section 2 unless otherwise
provided in this Plan, or in the applicable Stock Award Agreement, SAR Agreement
or Stock Option Agreement.

         on Form 8-K, as in effect on the date hereof, pursuant to Section 13 or
         15(d) of the Exchange Act; provided that, without limitation, such a
         change in control shall be deemed to have occurred at such time as (a)
         any person is or becomes the "beneficial owner" (as defined in Rule
         13d-3 under the Exchange Act), directly or indirectly, of 50% or more
         of the combined voting power of the Company's voting securities; or (b)

         hereof whose election, or nomination for election by the Company's

         the Plan.

         The Committee may adopt such rules or guidelines as it deems
appropriate to implement the Plan. The Committee's determinations under the Plan

         (a) GENERAL RULES. Only Employees, Directors, Non-Employee Directors

Committee.

         (b) INCENTIVE STOCK OPTIONS. Only Key Employees who are common-law

SECTION 5. SHARES SUBJECT TO PLAN.

         (a) BASIC LIMITATIONS. The stock issuable under the Plan shall be
authorized but unissued Shares or treasury Shares. The aggregate number of
Shares reserved for Awards under the Plan shall not exceed 9,916,385 Shares on a
fully diluted basis, subject to adjustment pursuant to Section 10. In addition,
the total number of Shares underlying Awards of Restricted Stock, Stock
Appreciation Rights and Stock Units shall not exceed 1,200,000 Shares.

         (b) ADDITIONAL SHARES. If Stock Units, Options or SARs are forfeited or
if Options or SARs terminate for any other reason before being exercised, then
such Stock Units, Options or


                                       5
<PAGE>

SARs shall again become available for Awards under the Plan. If SARs are
exercised, then only the number of Shares (if any) actually issued in settlement
of such SARs shall reduce the number available under Section 5(a) and the
balance shall again become available for Awards under the Plan. If Restricted
Stock is forfeited, then such Restricted Stock shall again become available for
Awards under the Plan.

         (c) DIVIDEND EQUIVALENTS. Any dividend equivalents distributed under
the Plan shall not be applied against the number of Restricted Stock, Stock
Units, Options or SARs available for Awards, whether or not such dividend
equivalents are converted into Stock Units.

SECTION 6. TERMS AND CONDITIONS FOR AWARDS OF RESTRICTED STOCK AND STOCK UNITS.

         (a) TIME, AMOUNT AND FORM OF AWARDS. Awards under the Plan may be
granted in the form of Restricted Stock, in the form of Stock Units, or in any
combination of both. Restricted Stock or Stock Units may also be awarded in
combination with NSOs or SARs, and such an Award may provide that the Restricted
Stock or Stock Units will be forfeited in the event that the related NSOs or
SARs are exercised.

         (b) PAYMENT FOR AWARDS. No cash consideration shall be required of the
recipients of Restricted Stock or Stock Units under this Section 6.

         (c) VESTING CONDITIONS. Each Award of Restricted Stock or Stock Units
shall become vested, in full or in installments, upon satisfaction of the
conditions specified in the Stock Award Agreement. A Stock Award Agreement may
provide for accelerated vesting in the event of the Participant's death,
Disability, retirement, Change in Control or other events.

         (d) FORM AND TIME OF SETTLEMENT OF STOCK UNITS. Settlement of vested
Stock Units may be made in the form of (i) cash, (ii) Shares or (iii) any
combination of both. The actual number of Stock Units eligible for settlement
may be larger or smaller than the number included in the original Award, based
on predetermined performance factors. Methods of converting Stock Units into
cash may include (without limitation) a method based on the average Fair Market
Value of Shares over a series of trading days. Vested Stock Units may be settled
in a lump sum or in installments. The distribution may occur or commence when
all vesting conditions applicable to the Stock Units have been satisfied or have
lapsed, or it may be deferred to any later date. The amount of a deferred
distribution may be increased by an interest factor or by dividend equivalents.
Until an Award of Stock Units is settled, the number of such Stock Units shall
be subject to adjustment pursuant to Section 10.

         (e) DEATH OF RECIPIENT. Any Stock Units Award that becomes payable
after the Award recipient's death shall be distributed to the recipient's
beneficiary or beneficiaries. Each recipient of a Stock Units Award under the
Plan shall designate one or more beneficiaries for this purpose by filing the
prescribed form with the Company. A beneficiary designation may be changed by
filing the prescribed form with the Company at any time before the recipient's
death. If no beneficiary was designated or if no designated beneficiary survives
the recipient, then any Stock Units Award that becomes payable after the
recipient's death shall be distributed to the recipient's estate.


                                       6
<PAGE>

         (f) CREDITORS' RIGHTS. A holder of Stock Units shall have no rights
other than those of a general creditor of the Company. Stock Units represent an
unfunded and unsecured obligation of the Company, subject to the terms and
conditions of the applicable Stock Award Agreement.

         (g) EFFECT OF A CHANGE IN CONTROL. The Committee may determine, at the
time of making an Award or thereafter, that such Award shall become fully vested
in the event that a Change in Control occurs with respect to the Company. If the
Committee finds that there is a reasonable possibility that, within the
succeeding six (6) months, a Change in Control will occur with respect to the
Company, then the Committee at its sole discretion may determine that any or all
outstanding Awards shall become fully exercisable as to all Shares subject to
such Awards.

SECTION 7. TERMS AND CONDITIONS OF OPTIONS.

         (a) STOCK OPTION AGREEMENT. Each Grant under the Plan shall be
evidenced by a Stock Option Agreement between the Optionee and the Company. Such
Option shall be subject to all applicable terms and conditions of the Plan and
may be subject to any other terms and conditions that are not inconsistent with
the Plan and that the Committee deems appropriate for inclusion in a Stock
Option Agreement. The provisions of the various Stock Option Agreements entered
into under the Plan need not be identical. A Stock Option Agreement may provide
that new Options will be granted automatically to the Optionee when he or she
exercises the prior Options. The Stock Option Agreement shall also specify
whether the Option is an ISO or an NSO.

         (b) NUMBER OF SHARES. Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 10. Options granted to any
Optionee in a particular calendar year shall in no event exceed 25% of the
Shares authorized for Award under this Plan subject to adjustment in accordance
with Section 10.

         (c) EXERCISE PRICE. An Option's Exercise Price shall be established by
the Committee and set forth in a Stock Option Agreement. An Option's Exercise
Price shall not be less than 100% of the Fair Market Value (110% for 10-Percent
Shareholders) of a Share on the date of Grant. In the case of an NSO, a Stock
Option Agreement may specify an Exercise Price that varies in accordance with a
predetermined formula while the NSO is outstanding.

         (d) EXERCISABILITY AND TERM. Each Stock Option Agreement shall specify
the date when all or any installment of the Option is to become exercisable. The
Stock Option Agreement shall also specify the term of the Option; provided that
the term of an ISO, and to the extent required by applicable law a NSO, shall in
no event exceed ten (10) years from the date of Grant (five (5) years for ISO
Grants to 10-Percent Shareholders). A Stock Option Agreement may provide for
accelerated exercisability in the event of the Optionee's death, Disability,
retirement, Change in Control or other events and may provide for expiration
prior to the end of its term in the event of the termination of the Optionee's
Service. Options may be awarded in combination with SARs, and such an Award may
provide that the Options will not be exercisable unless the related SARs are
forfeited. NSOs may also be awarded in combination with


                                        7
<PAGE>

Restricted Stock or Stock Units, and such an Award may provide that the NSOs
will not be exercisable unless the related Restricted Stock or Stock Units are
forfeited. In no event shall the Company be required to issue fractional Shares
upon the exercise of an Option.

         (e) EFFECT OF A CHANGE IN CONTROL. The Committee may determine, at the
time of granting an Option or thereafter, that such Option shall become fully
exercisable as to all Shares subject to such Option in the event that a Change
in Control occurs with respect to the Company. If the Committee finds that there
is a reasonable possibility that, within the succeeding six (6) months, a Change
in Control will occur with respect to the Company, then the Committee at its
sole discretion may determine that any or all outstanding Options shall become
fully exercisable as to all Shares subject to such Options.

         (f) MODIFICATIONS OR ASSUMPTION OF OPTIONS. Within the limitations of
the Plan, the Committee may modify, extend or assume outstanding Options or may
accept the cancellation of outstanding options (whether granted by the Company
or by another issuer) in return for the grant of new Options for the same or a
different number of Shares and at the same Exercise Price. The foregoing
notwithstanding, no modification of an Option shall, without the consent of the
Optionee, alter or impair his or her rights or obligations under such Option.

         (g) TRANSFERABILITY OF OPTIONS. Except as otherwise provided in the
applicable Stock Option Agreement and then only to the extent permitted by
applicable law, no Option shall be transferable by the Optionee other than by
will or by the laws of descent and distribution. Except as otherwise provided in
the applicable Stock Option Agreement, an Option may be exercised during the
lifetime of the Optionee only by the Optionee or by the guardian or legal
representative of the Optionee. No Option or interest therein may be assigned,
pledged or hypothecated by the Optionee during his lifetime, whether by
operation of law or otherwise, or be made subject to execution, attachment or
similar process.

         (h) NO RIGHTS AS A STOCKHOLDER. An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by an Option until such person becomes entitled to receive such Shares
by filing a notice of exercise and paying the Exercise Price pursuant to the
terms of such Option.

         (i) RESTRICTIONS ON TRANSFER. Any Shares issued upon exercise of an
Option shall be subject to such rights of repurchase, rights of first refusal
and other transfer restrictions as the Committee may determine. Such
restrictions shall apply in addition to any restrictions that may apply to
holders of Shares generally and shall also comply to the extent necessary with
applicable law.

         (j) AUTOMATIC OPTION GRANTS TO NON-EMPLOYEE DIRECTORS. Non-Employee
Directors shall automatically be Granted NSOs ("Automatic Option Grants") as set
forth in this Section 7(j) (subject to adjustment under Section 10).

                  (i) Each Non-Employee Director shall receive an Automatic
         Option Grant for 6,000 Shares on the first trading day in June on or
         after his or her initial election or appointment. However, any
         Non-Employee Director who is first elected or appointed after May 31 of
         any year (and who is not already serving on the Board at that time)
         shall


                                       8
<PAGE>

         receive an Automatic Option Grant on the date of such initial election
         or appointment for the number of Shares he or she would have received
         on the first trading day in June of that year had he or she then been
         eligible. In addition, on each anniversary of each Non-Employee
         Director's initial Automatic Option Grant, each such continuing
         Non-Employee Director shall receive an additional Automatic Option
         Grant for an amount of Shares that is equal to 110% of the number of
         Shares (rounded down to the nearest whole number) he or she received
         under the previous year's Automatic Option Grant.

                  (ii) The terms and conditions applicable to each Automatic
         Option Grant shall be as contained in this Section 7(j)(ii). The Option
         Exercise Price shall be equal to one hundred percent (100%) of the Fair
         Market Value of one Share on the date of Grant. Each Automatic Option
         Grant shall have a term of ten (10) years measured from the date of
         Grant. Fully vested Shares shall be exercisable at any time beginning
         twelve (12) months after the date of Grant. No Options Granted under
         this Plan may be exercised prior to Plan approval by the Company's
         stockholders. Upon exercise of the Option, the Exercise Price shall be
         payable immediately in cash or in Shares that the Optionee has held for
         at least six (6) months. Payment may also be made by delivery of a
         properly executed exercise notice together with irrevocable
         instructions to a broker to promptly deliver to the Company the amount
         of sale or loan proceeds to pay the Exercise Price. In the event the
         Optionee ceases to provide Services as a Non-Employee Director,
         outstanding vested Options may be exercised, within the term of such
         Options, for a period of three (3) months after the date of such
         cessation of Board service. However, the post-Service Option exercise
         period shall be twelve (12) months in the case of cessation by reason
         of the Optionee's Disability or death. In the case of death, the Option
         may be exercised within such twelve (12) month period by the estate or
         heirs of the Optionee.

                  (iii) This Automatic Option Grant program for the Non-Employee
         Directors shall be self-executing in accordance with its terms as
         provided for under the Plan, and neither the Board or Committee shall
         exercise any discretionary functions with respect to any Option Grants
         made under this program. Notwithstanding the preceding sentence, the
         full Board in its sole discretion may make additional NSO Grants to one
         or more Non-Employee Directors on such terms and conditions as the
         Board determines.

SECTION 8. PAYMENT FOR OPTION SHARES.

         (a) GENERAL RULE. The entire Exercise Price of Shares issued upon
exercise of Options shall be payable in cash at the time when such Shares are
purchased, except as follows:

                  (i) In the case of an ISO granted under the Plan, payment
         shall be made only pursuant to the express provisions of the applicable
         Stock Option Agreement. The Stock Option Agreement may specify that
         payment may be made in any form(s) described in this Section 8.

                  (ii) In the case of an NSO granted under the Plan, the
         Committee may at any time accept payment in any form(s) described in
         this Section 8.


                                       9
<PAGE>

         (b) SURRENDER OF STOCK. To the extent that this Section 8(b) is
applicable, payment for all or any part of the Exercise Price may be made with
Shares which have already been owned by the Optionee for such duration as shall
be specified by the Committee. Such Shares shall be valued at their Fair Market
Value on the date when the new Shares are purchased under the Plan.

         (c) PROMISSORY NOTE. To the extent that this Section 8(c) is
applicable, payment for all or any part of the Exercise Price may be made with a
full-recourse promissory note.

         (d) CASHLESS EXERCISE. To the extent that this Section 8(d) is
applicable, payment for all or any part of the Exercise Price may be made by
delivery (on a form prescribed by the Company) of an irrevocable direction to a
securities broker to sell Shares and to deliver all or part of the sale proceeds
to the Company.

         (e) OTHER FORMS OF PAYMENT. To the extent that this Section 8(e) is
applicable, and with Committee approval, payment may be made in any other form
that is consistent with applicable laws, regulations and rules.

SECTION 9. STOCK APPRECIATION RIGHTS.

         (a) SAR AGREEMENT. Each Award of a SAR under the Plan shall be
evidenced by a SAR Agreement between the Optionee and the Company. Such SAR
shall be subject to all applicable terms of the Plan and may be subject to any
other terms that are not inconsistent with the Plan. The provisions of the
various SAR Agreements entered into under the Plan need not be identical. SARs
may be granted in consideration of a reduction in the Optionee's other
compensation.

         (b) NUMBER OF SHARES. Each SAR Agreement shall specify the number of
Shares to which the SAR pertains and shall provide for the adjustment of such
number in accordance with Section 10.

         (c) EXERCISE PRICE. Each SAR Agreement shall specify the Exercise
Price. A SAR Agreement may specify an Exercise Price that varies in accordance
with a predetermined formula while the SAR is outstanding.

         (d) EXERCISABILITY AND TERM. Each SAR Agreement shall specify the date
when all or any installment of the SAR is to become exercisable. The SAR
Agreement shall also specify the term of the SAR. A SAR Agreement may provide
for accelerated exercisability in the event of the Optionee's death, Disability,
retirement, Change in Control or other events and may provide for expiration
prior to the end of its term in the event of the termination of the Optionee's
Service. SARs may also be awarded in combination with Options, Restricted Stock
or Stock Units, and such an Award may provide that the SARs will not be
exercisable unless the related Options, Restricted Stock or Stock Units are
forfeited. A SAR may be included in an ISO only at the time of Grant but may be
included in an NSO at the time of Grant or at any subsequent time, but not later
than six (6) months before the expiration of such NSO. A SAR granted under the
Plan may provide that it will be exercisable only in the event of a Change in
Control.


                                       10
<PAGE>

         (e) EFFECT OF CHANGE IN CONTROL. The Committee may determine, at the
time of awarding a SAR or thereafter, that such SAR shall become fully
exercisable as to all Shares subject to such SAR in the event that a Change in
Control occurs with respect to the Company. If the Committee finds that there is
a reasonable possibility that, within the succeeding six months, a Change in
Control will occur with respect to the Company, then the Committee at its sole
discretion may determine that any or all outstanding SARs shall become fully
exercisable as to all Shares subject to such SARs.

         (f) EXERCISE OF SARS. If, on the date when a SAR expires, the Exercise
Price under such SAR is less than the Fair Market Value on such date but any
portion of such SAR has not been exercised or surrendered, then such SAR shall
automatically be deemed to be exercised as of such date with respect to such
portion. Upon exercise of a SAR, the Optionee (or any person having the right to
exercise the SAR after his or her death) shall receive from the Company (i)
Shares, (ii) cash or (iii) a combination of Shares and cash, as the Committee
shall determine. The amount of cash and/or the Fair Market Value of Shares
received upon exercise of SARs shall, in the aggregate, be equal to the amount
by which the Fair Market Value (on the date of surrender) of the Shares subject
to the SARs exceeds the Exercise Price.

         (g) MODIFICATION OR ASSUMPTION OF SARS. Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding SARs or may accept
the cancellation of outstanding SARs (whether granted by the Company or by
another issuer) in return for the Award of new SARs for the same or a different
number of Shares and at the same or a different Exercise Price. The foregoing
notwithstanding, no modification of a SAR shall, without the consent of the
Optionee, alter or impair his or her rights or obligations under such SAR.

SECTION 10. PROTECTION AGAINST DILUTION.

         (a) ADJUSTMENTS. In the event of a subdivision of the outstanding
Shares, a declaration of a dividend payable in Shares, a declaration of a
dividend payable in a form other than Shares in an amount that has a material
effect on the price of Shares, a combination or consolidation of the outstanding
Shares (by reclassification or otherwise) into a lesser number of Shares, a
recapitalization, a spin-off or a similar occurrence, the Committee shall make
such adjustments as it, in its sole discretion, deems appropriate in one or more
of:

                  (i) the number of Options, SARs, Restricted Stock and Stock
         Units available for future Awards under Section 5;

                  (ii) the number of Stock Units included in any prior Award
         which has not yet been settled;

                  (iii) the number of Shares covered by each outstanding Option
         and SAR; or

                  (iv) the Exercise Price under each outstanding Option and SAR.

Except as provided in this Section 10, a Participant shall have no rights by
reason of any issue by the Company of stock of any class or securities
convertible into stock of any class, any


                                       11
<PAGE>

subdivision or consolidation of shares of stock of any class, the payment of any
stock dividend or any other increase or decrease in the number of shares of
stock of any class.

         (b) REORGANIZATIONS. In the event that the Company is a party to a
merger or other reorganization, outstanding Options, SARs, Restricted Stock and
Stock Units shall be subject to the agreement of merger or reorganization. Such
agreement may provide, without limitation, for the assumption of outstanding
Awards by the surviving corporation or its parent, for their continuation by the
Company (if the Company is a surviving corporation), for accelerated vesting and
accelerated expiration, or for settlement in cash or for cancellation.

SECTION 11. VOTING AND DIVIDEND RIGHTS.

         (a) RESTRICTED STOCK. The holders of Restricted Stock awarded under the
Plan shall have the same voting, dividend and other rights as the Company's
other stockholders. A Stock Award Agreement, however, may require that the
holders of Restricted Stock invest any cash dividends received in additional
Restricted Stock. Such additional Restricted Stock shall be subject to the same
conditions and restrictions as the Award with respect to which the dividends
were paid. Such additional Restricted Stock shall not reduce the number of
Shares available under Section 5.

         (b) STOCK UNITS. The holders of Stock Units shall have no voting
rights. Prior to settlement or forfeiture, any Stock Unit awarded under the Plan
may, at the Committee's discretion, carry with it a right to dividend
equivalents. Such right entitles the holder to be credited with an amount equal
to all cash dividends paid on one Share while the Stock Unit is outstanding.
Dividend equivalents may be converted into additional Stock Units. Settlement of
dividend equivalents may be made in the form of cash, in the form of Shares, or
in a combination of both. Prior to distribution, any dividend equivalents which
are not paid shall be subject to the same conditions and restrictions as the
Stock Units to which they attach.

SECTION 12. AWARDS UNDER OTHER PLANS.

         The Company may grant awards under other plans or programs. Such awards
may be settled in the form of Shares issued under this Plan. Such Shares shall
be treated for all purposes under the Plan like Shares issued in settlement of
Stock Units and shall, when issued, reduce the number of Shares available under
Section 5.

SECTION 13. LIMITATIONS ON RIGHTS.

         (a) RETENTION RIGHTS. Neither the Plan nor any Award granted under the
Plan shall be deemed to give any individual a right to remain an employee,
consultant or director of the Company or a Subsidiary. The Company and its
Subsidiaries reserve the right to terminate the Service of any person at any
time, and for any reason, subject to applicable laws, the Company's certificate
of incorporation and by-laws and a written employment agreement (if any).


                                       12
<PAGE>

         (b) STOCKHOLDERS' RIGHTS. A Participant shall have no dividend rights,
voting rights or other rights as a stockholder with respect to any Shares
covered by his or her Award prior to the issuance of a stock certificate for
such Shares. No adjustment shall be made for cash dividends or other rights for
which the record date is prior to the date when such certificate is issued,
except as expressly provided in Sections 6, 10 and 11.

         (c) REGULATORY REQUIREMENTS. Any other provision of the Plan
notwithstanding, the obligation of the Company to issue Shares under the Plan
shall be subject to all applicable laws, rules and regulations and such approval
by any regulatory body as may be required. The Company reserves the right to
restrict, in whole or in part, the delivery of Shares pursuant to any Award
prior to the satisfaction of all legal requirements relating to the issuance of
such Shares, to their registration, qualification or listing or to an exemption
from registration, qualification or listing.

SECTION 14. WITHHOLDING TAXES.

         (a) GENERAL. To the extent required by applicable federal, state, local
or foreign law, a Participant or his or her successor shall make arrangements
satisfactory to the Company for the satisfaction of any withholding tax
obligations that arise in connection with the Plan. The Company shall not be
required to issue any Shares or make any cash payment under the Plan until such
obligations are satisfied.

         (b) SHARE WITHHOLDING. The Committee may permit a Participant to
satisfy all or part of his or her withholding or income tax obligations by
having the Company withhold all or a portion of any Shares that otherwise would
be issued to him or her or by surrendering all or a portion of any Shares that
he or she previously acquired. Such Shares shall be valued at their Fair Market
Value on the date when taxes otherwise would be withheld in cash. Any payment of
taxes by assigning Shares to the Company may be subject to restrictions,
including any restrictions required by rules of the Securities and Exchange
Commission.

SECTION 15. ASSIGNMENT OR TRANSFER OF AWARDS.

         (a) GENERAL. Except as provided in Section 14, or in an applicable
agreement, or as required by applicable law, an Award granted under the Plan
shall not be anticipated, assigned, attached, garnished, optioned, transferred
or made subject to any creditor's process, whether voluntarily, involuntarily or
by operation of law. An Option or SAR may be exercised during the lifetime of
the Optionee only by him or her or by his or her guardian or legal
representative. Any act in violation of this Section 15 shall be void. However,
this Section 15 shall not preclude a Participant from designating a beneficiary
who will receive any outstanding Awards in the event of the Participant's death,
nor shall it preclude a transfer of Awards by will or by the laws of descent and
distribution.

         (b) TRUSTS. Neither this Section 15 nor any other provision of the Plan
shall preclude a Participant from transferring or assigning Restricted Stock or
Stock Units to (a) the trustee of a trust that is revocable by such Participant
alone, both at the time of the transfer or assignment and at all times
thereafter prior to such Participant's death, or (b) the trustee of any other
trust to


                                       13
<PAGE>

the extent approved in advance by the Committee in writing. A transfer or
assignment of Restricted Stock or Stock Units from such trustee to any person
other than such Participant shall be permitted only to the extent approved in
advance by the Committee in writing, and Restricted Stock or Stock Units held by
such trustee shall be subject to all of the conditions and restrictions set
forth in the Plan and in the applicable Stock Award Agreement, as if such
trustee were a party to such Agreement.

SECTION 16. DURATION AND AMENDMENTS.

         (a) TERM OF THE PLAN. The Plan, as set forth herein, shall terminate,
subject to Section 16(b), no later than January 1, 2004.

         (b) RIGHT TO AMEND OR TERMINATE THE PLAN. The Board may amend or
terminate the Plan at any time and for any reason. The termination of the Plan,
or any amendment thereof, shall not affect any Award previously granted under
the Plan. No Awards shall be granted under the Plan after the Plan's
termination. The Board may not, without the approval of the Company's
stockholders (i) materially increase the number of Shares subject to Awards
under the Plan (unless necessary to effect the adjustments required under
Section 10)), (ii) materially modify the eligibility requirements for Awards
under the Plan, or (iii) make any other change with respect to which the Board
determines that Company stockholder approval is required by applicable law or
regulatory standards.

SECTION 17. EXECUTION.

         To record the adoption of the Plan by the Board, the Company has caused
its duly authorized officer to execute this Plan.

Stock Purchase Plan of Cygnus, Inc., as last amended and restated on March 1,
2000.

         1. PURPOSE. The purpose of the Plan is to provide Employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company through accumulated payroll deductions. It is the intention
of the Company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

         2. DEFINITIONS.

                  (a) "BOARD" shall mean the Board of Directors of the Company

of leave exceeds 90 days and the individual's right to reemployment is not
guaranteed either by statute or by contract, the employment relationship will be
deemed to have terminated on the 91st day of such leave.

reported), as quoted on such exchange (or the exchange with the greatest volume
of trading in Common Stock) or system on the day of such determination, as
reported in The Wall Street Journal or such other source as the Board deems
reliable, or;

                           (2) If the Common Stock is quoted on the NASDAQ
system (but not on the National Market System thereof) or is regularly quoted by

                  (b) Any provisions of the Plan to the contrary
notwithstanding, no Employee shall be granted a purchase right under the Plan
(i) if, immediately after the grant, such Employee (or any other person whose
stock would be attributed to such Employee pursuant to Section 424(d) of the
Code) would own stock and/or hold outstanding purchase rights to purchase stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or of any Subsidiary of the Company, or
(ii) which permits his or her rights to purchase stock under all employee stock
purchase plans of the Company and its Subsidiaries to accrue at a rate which
exceeds Twenty-Five Thousand Dollars ($25,000) worth of stock (determined at the
fair market value of the shares at the time such purchase right is granted) for
each calendar year in which such purchase right is outstanding at any time.

         4. OFFERING PERIODS. The Plan shall be implemented by consecutive and
overlapping Offering Periods. The Board shall have the power to change the

         6. PAYROLL DEDUCTIONS.

                  (a) At the time a Participant files his or her subscription

said Offering Period.

                  (b) All payroll deductions made for a Participant shall be
credited to his or her account under the Plan and will be withheld in whole
percentages only. A Participant may not make any additional payments into such
account.

                  (c) A Participant may discontinue his or her participation in
the Plan as provided in Section 10, or may increase or decrease the rate of his
or her payroll deductions during the current Purchase Period by filing with the
Company a new subscription agreement authorizing such a change in the payroll
deduction rate. A reduction to a 0% rate of contribution shall be treated as a
withdrawal from the Plan effective with the following Purchase Period unless
such rate is increased prior to the following Purchase Period. The change in
rate shall be effective with the first full payroll period following such
advance notice period as the Company shall specify. A Participant's subscription
agreement shall remain in effect for successive Purchase Periods and Offering
Periods unless terminated as provided in Section 10. The Board shall be
authorized to limit the number of participation rate changes during any Offering
Period. A Participant may at any time elect to have his or her participation
agreement become irrevocable for such period of time as he or she may designate.

                  (d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) herein, a
Participant's payroll deductions may be decreased to 0% at such time during any
Purchase Period which is scheduled to end during the current calendar year (the
"Current Purchase Period") that the aggregate of all payroll deductions which
were previously used to purchase stock under the Plan in a prior Purchase Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Purchase Period equal $21,250. The Company may
provide either (i) that payroll deductions shall recommence at the rate provided
in such Participant's subscription agreement at the beginning of the first
Purchase Period which is scheduled to end in the following calendar year, unless
terminated by the Participant as provided in Section 10, or (ii) that
participation shall recommence only upon filing a new enrollment form following
such waiting period as the Company shall specify.

                  (e) At the time the purchase right is exercised, in whole or
in part, or at the time some or all of the Company's Common Stock issued under
the Plan is disposed of, the Participant must make adequate provision for the
Company's federal, state, or other tax withholding


                                       4.
<PAGE>

obligations, if any, which arise upon the exercise of the purchase right or the
disposition of the Common Stock. At any time, the Company may, but will not be
obligated to, withhold from the Participant's compensation the amount necessary
for the Company to meet applicable withholding obligations, including any
withholding required to make available to the Company any tax deductions or
benefit attributable to sale or early disposition of Common Stock by the
Employee.

         7. GRANT OF PURCHASE RIGHT. On the Enrollment Date of each Offering
Period, each eligible Employee participating in such Offering Period shall be
granted a purchase right to purchase on each Exercise Date during such Offering
Period (at the applicable Purchase Price) up to a number of shares of the
Company's Common Stock determined by dividing such Employee's payroll deductions
accumulated prior to such Exercise Date and retained in the Participant's
account as of the Exercise Date by the applicable Purchase Price; provided that
such purchase shall be subject to the limitations set forth in Section 3(b) and
12 hereof. Exercise of the purchase right shall occur as provided in Section 8,
unless the Participant has withdrawn pursuant to Section 10, and the purchase
right shall expire on the last day of the Offering Period.

         8. EXERCISE OF PURCHASE RIGHT. Unless a Participant withdraws from the
Plan as provided in Section 10 below, his or her purchase right for the purchase
of shares of Common Stock will be exercised automatically on each Exercise Date,
and the maximum number of full shares subject to the purchase right shall be
purchased for such Participant at the applicable Purchase Price with the
accumulated payroll deductions in his or her account. No fractional shares will
be purchased. Any payroll deductions accumulated in a Participant's account
which are not sufficient to purchase a full share shall be retained in the
Participant's account for the subsequent Purchase Period, subject to earlier
withdrawal by the Participant as provided in Section 10. During a Participant's
lifetime, a Participant's purchase right to purchase shares hereunder is
exercisable only by him or her.

         9. DELIVERY. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery of
purchased shares to a directed brokerage account. Certificates representing the
shares that were purchased by each Participant will remain with the brokerage
account until such time as the Participant (or beneficiary) requests that their
shares be transferred out of the brokerage account.

         10. WITHDRAWAL; TERMINATION OF EMPLOYMENT.

                  (a) A Participant may, subject to the terms of any irrevocable
participation agreement elected by the Participant, withdraw all but not less
than all the payroll deductions credited to his or her account and not yet used
to exercise his or her purchase right under the Plan at any time by giving
written notice to the Company in the form provided by the Company. All of the
Participant's payroll deductions credited to his or her account will be paid to
such Participant promptly after receipt of notice of withdrawal and such
Participant's purchase right for the Offering Period will be automatically
terminated, and no further payroll deductions for the purchase of shares will be
made during the Offering Period. If a Participant withdraws from an Offering
Period, payroll deductions will not resume at the beginning of the succeeding
Offering Period unless the Participant delivers to the Company a new
subscription agreement.


                                       5.
<PAGE>

                  (b) Upon a Participant's ceasing to be an Employee for any
reason or upon termination of a Participant's employment relationship (as
described in Section 2(g)), the payroll deductions credited to such
Participant's account during the Offering Period but not yet used to exercise
the purchase right will be returned to such Participant or, in the case of his
or her death, to the person or persons entitled thereto under Section 14, and
such Participant's purchase right will be automatically terminated. The Company
may reduce the amount returned to a Participant by the amount of any outstanding
debts that the Participant owes to either the Company or a Subsidiary.

         11. INTEREST. No interest shall accrue on the payroll deductions of a
Participant in the Plan.

         12. STOCK.

                  (a) The maximum number of shares of the Company's Common Stock
which shall be made available for sale under the Plan shall be 1,975,000 shares,
subject to adjustment upon changes in capitalization of the Company as provided
in Section 18. If on a given Exercise Date the number of shares with respect to
which purchase rights are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable.

                  (b) The Participant will have no interest or voting right in
shares covered by this purchase right until such purchase right has been
exercised.

                  (c) Shares to be delivered to a Participant under the Plan
will be registered in the name of the Participant or in the name of the
Participant and his or her spouse.

         13. ADMINISTRATION. The Plan shall be administered by the Board of the
Company or a committee of one or more members of the Board as appointed by the
Board. Committee members serve for the period of time specified by the Board of
Directors and can be removed from the committee by the Board at any time. The
Board or its committee shall have full and exclusive discretionary authority to
construe, interpret and apply the terms of the Plan, to determine eligibility
and to adjudicate all disputed claims filed under the Plan. Every finding,
decision and determination made by the Board or its committee shall, to the full
extent permitted by law, be final and binding upon all parties.

         14.      DESIGNATION OF BENEFICIARY.

                  (a) A Participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
Participant's account under the Plan in the event of such Participant's death
subsequent to an Exercise Date on which the purchase right is exercised but
prior to delivery to such Participant of such shares and cash. In addition, a
Participant may file a written designation of a beneficiary who is to receive
any cash from the Participant's account under the Plan in the event of such
Participant's death prior to exercise of the purchase right. If a Participant is
married and the designated beneficiary is not the spouse, spousal consent shall
be required for such designation to be effective.


                                       6.
<PAGE>

                  (b) Such designation of beneficiary may be changed by the
Participant (and his or her spouse, if any) at any time by written notice. In
the event of the death of a Participant and in the absence of a beneficiary
validly designated under the Plan who is living at the time of such
Participant's death, the Company shall deliver such shares and/or cash to the
executor or administrator of the estate of the Participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such shares and/or cash to the
spouse or to any one or more dependents or relatives of the Participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

         15. TRANSFERABILITY. Neither payroll deductions credited to a
Participant's account nor any rights with regard to the exercise of a purchase
right or to receive shares under the Plan may be assigned, transferred, pledged
or otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10.

         16. USE OF FUNDS. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

         17. REPORTS. Individual accounts will be maintained for each
Participant in the Plan. Statements of account will be given to participating
Employees at least annually, which statements will set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

         18. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR
ASSET SALE.

                  (a) CHANGES IN CAPITALIZATION. Subject to any required action
by the shareholders of the Company, the Reserves as well as the price per share
of Common Stock covered by each purchase right under the Plan which has not yet
been exercised, shall be proportionately adjusted for any increase or decrease
in the number of issued shares of Common Stock resulting from a stock split,
reverse stock split, stock dividend, combination or reclassification of the
Common Stock, or any other increase or decrease in the number of shares of
Common Stock effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Board, whose determination in that respect shall
be final, binding and conclusive. Except as expressly provided herein, no issue
by the Company of shares of stock of any class, or securities convertible into
shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares of Common Stock
subject to a purchase right. The Board may, if it so determines in the exercise
of its sole discretion, make provision for adjusting the Reserves, as well as
the price per share of Common Stock covered by each outstanding purchase


                                       7.
<PAGE>

right, in the event the Company effects one or more reorganizations,
recapitalizations, rights offerings or other increases or reductions of shares
of its outstanding Common Stock.

                  (b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Offering Periods will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

                  (c) MERGER OR ASSET SALE. In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, each purchase right under the Plan
shall be assumed or an equivalent purchase right shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Board determines, in the exercise of its sole discretion and in lieu
of such assumption or substitution, to shorten the Offering Periods then in
progress by setting a new Exercise Date (the "New Exercise Date"). If the Board
shortens the Offering Periods then in progress in lieu of assumption or
substitution in the event of a merger or sale of assets, the Board shall notify
each Participant in writing, at least ten (10) days prior to the New Exercise
Date, that the Exercise Date for his purchase right has been changed to the New
Exercise Date and that his purchase right will be exercised automatically on the
New Exercise Date, unless prior to such date he has withdrawn from the Offering
Period as provided in Section 10. For purposes of this Section, a purchase right
granted under the Plan shall be deemed to be assumed or substituted if
accomplished in accordance with Section 424 of the Code.

         19. AMENDMENT OR TERMINATION.

                  (a) The Board of Directors of the Company may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 18, no
such termination can affect purchase rights previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its shareholders. Except as provided in Section 18,
no amendment may make any change in any purchase right theretofore granted which
adversely affects the rights of any Participant. To the extent necessary to
comply with Rule 16b-3 or under Section 423 of the Code (or any successor rule
or provision or any other applicable law or regulation), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

                  (b) Without shareholder consent and without regard to whether
any Participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Purchase Periods and/or
Offering Periods (subject to Section 4), limit the frequency and/or number of
changes in the amount withheld during Purchase Periods and/or Offering Periods,
establish the exchange ratio applicable to amounts withheld in a currency other
than U.S. dollars, permit payroll withholding in excess of the amount designated
by a Participant in order to adjust for delays or mistakes in the Company's
processing of properly completed withholding elections, establish reasonable
waiting and adjustment periods and/or accounting and crediting procedures to
ensure that amounts applied toward the purchase of Common Stock for each
Participant properly correspond with amounts withheld from the Participant's
Compensation,


                                       8.
<PAGE>

and establish such other limitations or procedures as the Board (or its
committee) determines in its sole discretion advisable which are consistent with
the Plan.

         20. NOTICES. All notices or other communications by a Participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

         21. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with
respect to a purchase right unless the exercise of such purchase right and the
issuance and delivery of such shares pursuant thereto shall comply with all
applicable provisions of law, domestic or foreign, including, without
limitation, the Securities Act of 1933, as amended, the Securities Exchange Act
of 1934, as amended, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the shares may then be listed, and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

         22. TERM OF PLAN. The Plan was originally effective on August 1, 1991.
The Plan shall continue in effect through July 31, 2011 unless sooner terminated
under Section 19.

         23. AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD. If the Fair Market
Value of the Common Stock on any Exercise Date in an Offering Period is lower
than the Enrollment Date Price of such Offering Period, then all Participants in
such Offering Period shall be automatically withdrawn from such Offering Period
immediately after the exercise of their purchase rights on such Exercise Date
and automatically reenrolled in the immediately following Offering Period as of
the first day thereof.

         24. EXECUTION. To record the adoption of this amended and restated Plan
by the Board, the Company has caused its duly authorized officer to sign below.
