Prospectus summary

This summary highlights information contained in other parts of this prospectus.
Because it is a summary, it does not contain all of the information you should
consider before investing in our common stock. You should read the entire
prospectus carefully including "Risk factors" and the financial statements and
related notes before making an investment decision.

OUR BUSINESS

We are a pioneer in the development, manufacturing and marketing of innovative
products that enable chemists to use high speed parallel synthesis for the
development of new drugs. Parallel synthesis is a process by which chemists
create multiple compounds. Our products include a variety of parallel chemical
synthesizers and reagents. Our products enable chemists to increase their
productivity, accelerate the drug development process and reduce costs.
Currently, our products are used for chemistry development by chemists in the
pharmaceutical, biotechnology, life sciences and chemical research fields
worldwide.

Advances in the drug discovery process have resulted in a significant increase
in the number of new tools and targets for the development of new drugs, or drug
targets. However, unlike drug discovery, drug development lacks the
technological advances and automation that would allow efficient utilization of
new targets. As a result, many companies are seeking innovative and
cost-effective tools and technologies that would be used to explore the
increasing number of targets for the potential development of new drugs. Our
instruments enable parallel synthesis and automate many of the most
labor-intensive steps of chemistry development. Through automation, chemists are
able to perform multiple experiments under a variety of conditions in a fraction
of the time it would take to perform the same experiments using traditional
chemistry development methods. We believe that our products will enable
companies to develop new drugs in a more productive, faster and more
cost-effective manner than by using traditional chemistry development methods.
Therefore companies, through the use of our products, may capitalize on the
wealth of potential new drug targets being generated by the drug discovery
process.

We began marketing our first product in 1996. Currently, we have eight
instrument product offerings and more than 40 reagent product offerings. Through
March 31, 2000, we have sold our products to more than 545 customers in the
pharmaceutical, biotechnology, life sciences and chemical research industries
and have placed more than 640 instruments worldwide. In addition, we have a
track record of quickly and effectively developing solutions to our customers'
problems. In order to ensure that our products meet the specific needs of
chemists throughout the research community, we have formed formal consortia and
informal relationships with teams of industry leaders and academic institutions
for each of our instruments released to date. Through this process we have
developed innovative products that have extensive customer input, validation and
testing prior to commercial introduction.

OUR MARKET OPPORTUNITY

The life sciences research industry is undergoing fundamental change resulting
principally from the explosive growth in gene discovery and the increasing
demand for greater efficiency in the drug discovery and development process.
Industry experts estimate that in the year 2000 the life sciences research
industry will spend more than $70 billion on drug discovery research and
development. Advances in genomics, combinatorial chemistry and high throughput
screening have significantly enhanced the discovery process. Genomics, the
mapping of the human DNA sequence and the study of the role genes play in
disease, is creating an unprecedented wealth of information concerning potential

- --------------------------------------------------------------------------------
                                                                               3

drug targets. Industry sources estimate that sequencing of the human genome will
provide an estimated 3,000 to 10,000 relevant new drug targets over the next ten
years, compared to the approximately 500 targets that have been explored thus
far. Combinatorial chemistry is the rapid synthesis of large collections of
potential drug candidates. Through combinatorial chemistry, chemists can
generate chemical collections, or libraries, consisting of millions of compounds
that researchers can screen against drug targets through the use of high
throughput screening technologies. Chemists have been able to make these
advances in drug discovery by using new tools that simplify, automate and
accelerate the drug discovery process. Through widespread use of these tools
chemists are discovering a large number of new drug candidates that are ready
for the drug development process. However, the pharmaceutical industry does not
have sufficient tools and resources to fully exploit the opportunities presented
by advances in drug discovery due to the technological limitations of
traditional drug development, or chemistry development.

Traditional chemistry development methods have the following limitations:

+  traditional methods are time consuming and inefficient, due to the
   labor-intensive nature of this process;

+  traditional methods require compounds to be synthesized one at a time. This
   results in long drug development timelines, which delay product
   commercialization and reduce the exclusivity period provided by patent
   protection;

+  traditional methods are expensive due to the time and labor required of a
   chemist to produce a single compound;

+  traditional methods limit the number of compounds synthesized, which can lead
   to the selection of sub-optimal drug candidates, often resulting in drug
   candidate failures;

+  chemists lack flexible tools and systems necessary to easily perform the wide
   variety of complex experiments required for chemistry development; and

+  traditional methods are often difficult to employ and require skilled,
   scientific personnel.

THE ARGONAUT SOLUTION

We design, manufacture and market instruments and reagents that increase the
productivity of chemists, thereby accelerating the drug development process. Our
products enable the rapid synthesis of a wide range of compounds at a reduced
cost. We intend to promote our products as the laboratory standard for chemists
and the industry standard for companies seeking more efficient methods of
addressing their increasing drug development needs. We believe our technology
provides the following key benefits compared to traditional chemistry
development methods:

+  increased productivity;

+  reduced drug development timelines;

+  reduced cost;

+  improved intellectual property positions;

+  flexibility; and

+  ease of use.

Our strategy is to become the leading provider of productivity and quality
enhancing tools for all stages of the drug development process. In order to
achieve this goal, we have implemented the following strategy:

+  focus initially on industry leaders within the pharmaceutical market;

+  expand our high-value reagent business;

+  continue to establish product development consortia and collaborations;

+  leverage global customer relationships through direct sales;

+  acquire complementary businesses; and

+  expand into new markets.

Risk factors

You should carefully consider the risks described below together with all of the
other information included in this prospectus before making an investment
decision. If any of the following risks actually occurs, our business, financial
condition or results of operations could be harmed. In such an event, the
trading price of our common stock could decline, and you may lose part or all of
your investment.

RISKS RELATED TO OUR BUSINESS

WE HAVE A HISTORY OF OPERATING LOSSES, AND WE MAY NEVER ACHIEVE OR SUSTAIN
PROFITABILITY.

We have incurred operating losses and negative cash flow from operations since
our inception. As of March 31, 2000, we had an accumulated deficit of $28.9
million. We recorded net losses of $6.2 million in 1997, $5.7 million in 1998,
$7.6 million in 1999 and $2.0 million for the three months ended March 31, 2000.
We expect to continue to incur operating and net losses and negative cash flow
from operations, which may increase, for the foreseeable future due in part to
anticipated increases in expenses for research and development and expansion of
our sales and marketing capabilities. We may never become profitable.

IF OUR PRODUCTS DO NOT BECOME WIDELY USED IN THE LIFE SCIENCES INDUSTRY, IT IS
UNLIKELY THAT WE WILL EVER BECOME PROFITABLE.

Pharmaceutical, biotechnology and life science companies have historically
performed chemistry development using traditional laboratory methods. To date,
our products have not been widely adopted by the life sciences industry. The
commercial success of our products will depend upon the adoption of these
products as a method to develop chemical compounds for the life sciences and
other industries. In order to be successful, our products must meet the
performance and pricing requirements for chemistry development within the life
sciences and other industries. Market acceptance will depend on many factors,
including our ability to:

+  convince prospective customers that our products are a cost-effective
   alternative to traditional methods and other technologies that may be
   introduced for chemistry development;

+  manufacture products in sufficient quantities with acceptable quality and at
   an acceptable cost; and

+  install and service sufficient quantities of our products.

If we cannot achieve these objectives, our products will not gain market
acceptance.

OUR PRODUCT DEVELOPMENT EFFORTS MAY NOT PRODUCE COMMERCIALLY VIABLE PRODUCTS.

We intend to devote significant personnel and financial resources to research
and development activities to develop new products. Such products may not be
successfully developed, and we may never realize any benefits from such research
and development activities. Even if we successfully develop new products, such
products may not be commercially viable within the life sciences industry. Our
ability to increase our revenues and achieve and sustain profitability is
dependent upon our ability to successfully develop new products that will
achieve market acceptance.

BECAUSE WE RECEIVE REVENUES PRINCIPALLY FROM LIFE SCIENCE AND CHEMICAL
COMPANIES, THE CAPITAL SPENDING POLICIES OF THESE ENTITIES HAVE A SIGNIFICANT
EFFECT ON THE DEMAND FOR OUR PRODUCTS.

Our customers include pharmaceutical, biotechnology, life science and other
chemical research companies, and the capital spending policies of these entities
can have a significant effect on the

- --------------------------------------------------------------------------------
 8
<PAGE>   11
RISK FACTORS
- --------------------------------------------------------------------------------

demand for our products. These policies are based on a wide variety of factors,
including the resources available for purchasing research equipment, the
spending priorities among various types of research equipment and the policies
regarding capital expenditures. In particular, the volatility of the public
stock market for biotechnology companies has at certain times significantly
impacted their ability to raise capital, which has directly affected their
capital spending budgets. In addition, continued consolidation within the
pharmaceutical industry will likely delay and may potentially reduce capital
spending by pharmaceutical companies involved in such consolidations. Any
decrease or delay in capital spending by life science companies could cause our
revenues to decline and harm our profitability.

OUR PRODUCTS HAVE LENGTHY SALES CYCLES, WHICH COULD CAUSE OUR OPERATING RESULTS
TO FLUCTUATE SIGNIFICANTLY FROM QUARTER TO QUARTER.

Our ability to obtain customers for our products depends in significant part
upon the perception that our products can help accelerate efforts in drug
development. The sale of many of our products typically involves a significant
technical evaluation and commitment of capital by customers. Accordingly, the
sales cycles of many of our products are lengthy and subject to a number of
significant risks that are beyond our control, including customers' budgetary
constraints and internal acceptance reviews. Due to this lengthy and
unpredictable sales cycle, our revenues could fluctuate significantly from
quarter to quarter. In particular, operating results in the first and third
quarters have historically been depressed. A large portion of our expenses,
including expenses for facilities, equipment and personnel, are relatively
fixed. Accordingly, if revenues decline or do not grow as we anticipate, we
might not be able to correspondingly reduce our operating expenses. Our failure
to achieve our anticipated levels of revenues could significantly harm our
operating results for a particular fiscal period. Due to the possibility of
fluctuations in our operating results, we believe that quarter-to-quarter
comparisons of our operating results are not always a good indication of our
future performance.

OUR DIRECT SALES FORCE MAY NOT BE SUFFICIENTLY LARGE OR KNOWLEDGEABLE TO
SUCCESSFULLY ADDRESS THE MARKET FOR OUR PRODUCTS.

We sell a major portion of our products through our own sales force. Our future
profitability will depend in part on our ability to expand our direct sales and
marketing force, which we may not be able to do. Our products are technical in
nature. As a result, we believe it is necessary that our direct sales force
includes people with scientific backgrounds and expertise. Competition for such
employees is intense. We may not be able to attract and retain qualified sales
people or be able to build an efficient and effective sales and marketing force.
Failure to attract or retain qualified sales people or to build an efficient and
effective sales and marketing force could negatively impact sales of our
products, thus reducing our revenues and profitability.

FAILURE TO EXPAND OUR INTERNATIONAL SALES AS WE INTEND WOULD REDUCE OUR ABILITY
TO BECOME PROFITABLE.

To achieve our sales objectives, we will need to sell a significant number of
our products outside of the United States. A successful international effort
will require us to expand our direct sales force to conduct international
operations and develop relationships with international dealers and
distributors. We may not be able to expand our sales force or identify, attract
or retain suitable international dealers and distributors. As a result, we may
be unsuccessful in our international expansion efforts. Furthermore, expansion
into international markets will require us to continue to establish and expand
foreign operations and hire additional personnel to run these operations.

                                                                               9
<PAGE>   12
RISK FACTORS
- --------------------------------------------------------------------------------

International operations involve a number of risks and burdens not typically
present in domestic operations, including:

+  preferences of certain customers to purchase goods manufactured in their own
   country or geographic market;

+  difficulties in staffing and managing foreign operations;

+  costs and risks of deploying systems in foreign countries;

+  licenses, tariffs and other trade barriers;

+  changes in regulatory requirements;

+  potentially adverse tax consequences;

+  the burden of complying with a wide variety of complex foreign laws and
   treaties; and

+  political and economic instability.

Our international operations will also be subject to the risks associated with
the imposition of legislation and regulations relating to the import or export
of high technology products. We cannot predict whether tariffs or restrictions
upon the exportation or importation of our products will be implemented by the
United States or other countries.

WE MAY LOSE OUR EXCLUSIVE LICENSE TO PROPRIETARY TECHNOLOGY INCORPORATED INTO
OUR PRODUCTS.

We have developed some of our products based on proprietary technology
originally developed by third parties. We currently have exclusive licenses to
use such technology in our products which are subject to termination in certain
events. In particular, our license to proprietary technology belonging to Symyx
which is incorporated into our Endeavor product is subject to termination at
Symyx's or our option upon six months prior notice at any time after December
31, 2000. If our licenses to any such technology, or any similar licenses we may
enter into in the future, are terminated we may be unable to continue selling
such products and our revenues would decline.

WE MAY HAVE DIFFICULTY MANAGING OUR GROWTH, WHICH COULD DAMAGE OUR ABILITY TO
INCREASE OUR REVENUES AND BECOME PROFITABLE.

Our growth has placed significant demands on our management and other resources.
Our future success will depend on our ability to manage our growth, including:

+  continuing to train, motivate, manage and retain our existing employees and
   to attract and assimilate new employees;

+  manufacturing on a timely basis increasing quantities of current products and
   new products under development while maintaining product quality;

+  expanding and improving our domestic and international sales and marketing
   capabilities; and

+  developing and improving our operational, financial, accounting and other
   internal systems and controls consistent with our pace of growth.

If we are unable to manage our growth, our ability to increase our revenues and
become profitable could be damaged.

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

<PAGE>   13
RISK FACTORS
- --------------------------------------------------------------------------------

WE ARE HIGHLY DEPENDENT ON THE PRINCIPAL MEMBERS OF OUR MANAGEMENT TEAM AND
OTHER KEY EMPLOYEES AND ON OUR ABILITY TO RECRUIT ADDITIONAL PERSONNEL.

We are highly dependent on the principal members of our management team and
scientific staff. The loss of the services of any of these persons could delay
or reduce our product development and commercialization efforts. None of the
principal members of our management team or our scientific staff have entered
into employment agreements with us. In addition, we will require additional
personnel in the areas of chemistry research, product development, manufacturing
and marketing, and finance and administration. In particular, it is difficult to
attract and retain qualified individuals with the requisite experience in
chemistry. We are currently searching for a Chief Financial Officer. We may not
be able to attract and retain the requisite personnel, which could seriously
harm our ability to manage our business.

IF WE NEED BUT ARE UNABLE TO OBTAIN ADDITIONAL FUNDING TO SUPPORT OUR
OPERATIONS, WE WOULD HAVE TO REDUCE OR CEASE OPERATIONS OR ATTEMPT TO SELL ALL
OR A PART OF OUR OPERATIONS.

We anticipate that our existing cash and cash equivalents, together with the net
proceeds of this offering, will be sufficient to fund our currently planned
operations through at least May 2002. However, this expectation is based on our
current operating plan, which could change as a result of many factors, and we
could require additional funding sooner than anticipated. To the extent our
capital resources are insufficient to meet our future capital requirements, we
will have to raise additional funds to continue the development and
commercialization of our products. Funds may not be available on favorable
terms, if at all. To the extent that we raise additional capital through the
sale of equity, the issuance of those securities could result in dilution to our
stockholders. Moreover, incurring debt financing could result in a substantial
portion of our operating cash flow being dedicated to the payment of principal
and interest on such indebtedness, could render us more vulnerable to
competitive pressures and economic downturns and could impose restrictions on
our operations. If adequate funds are not available, we may be required to
curtail operations significantly.

BECAUSE WE HAVE LIMITED SOURCES OF PRODUCTION AND SUPPLIERS, OUR ABILITY TO
PRODUCE AND SUPPLY OUR PRODUCTS COULD BE IMPAIRED.

We outsource most of the assembly of our products to vendors. Our reliance on
our outside vendors exposes us to risks including:

+  the possibility that one or more of our vendors could terminate their
   services at any time without notice;

+  reduced control over pricing, quality and timely delivery, due to the
   difficulties in switching to alternative vendors; and

+  the potential delays and expenses of seeking alternative sources of
   manufacturing services.

Consequently, in the event that components from our suppliers or work performed
by our vendors are delayed or interrupted for any reason, our ability to produce
and supply our products could be impaired.

IF WE CANNOT PROVIDE QUALITY CUSTOMER SERVICE, WE COULD LOSE CUSTOMERS AND OUR
OPERATING RESULTS COULD SUFFER.

The introduction of our products to new customers and the ongoing customer
support for installed products can be complex. Accordingly, we need highly
trained customer support and technical personnel. Our inability to attract,
train or retain the number of highly qualified customer support and technical
services personnel that our business needs may cause our customer relations to
suffer. We are

- --------------------------------------------------------------------------------
                                                                              11
<PAGE>   14
RISK FACTORS
- --------------------------------------------------------------------------------

currently expanding these areas and will need to increase our staff further to
support expected growth. Hiring customer support and technical personnel is very
competitive in our industry. There are a limited number of people available with
the necessary technical skills and understanding of our products.

IF WE MAKE ANY ACQUISITIONS, WE WILL INCUR A VARIETY OF COSTS AND MAY NEVER
REALIZE THE ANTICIPATED BENEFITS.

We may attempt to acquire businesses, technologies, services or products that we
believe are a strategic fit with our business. We currently have no commitments
or agreements with respect to any material acquisitions. Integrating any
acquired business, technology, service or product with our existing operations
may result in operating difficulties and expenditures and may absorb significant
management attention that would otherwise be available for ongoing development
of our business. Moreover, we may never realize the anticipated benefits of any
acquisition. Future acquisitions could result in potentially dilutive issuances
of equity securities, the incurrence of debt, contingent liabilities and
amortization expenses related to goodwill and other intangible assets.

WE MAY LOSE MONEY WHEN WE EXCHANGE FOREIGN CURRENCY RECEIVED FROM INTERNATIONAL
SALES INTO U.S. DOLLARS.

A portion of our business is conducted in currencies other than the U.S. dollar.
We recognize foreign currency gains or losses arising from our operations in the
period incurred. As a result, currency fluctuations between the U.S. dollar and
the currencies in which we do business will cause us to incur foreign currency
translation gains and losses. We cannot predict the effects of exchange rate
fluctuations upon our future operating results because of the number of
currencies involved, the variability of currency exposure and the potential
volatility of currency exchange rates. We do not currently engage in foreign
exchange hedging transactions to manage the risk of our foreign currency
exposure.

RISKS RELATED TO OPERATING IN OUR INDUSTRY

THE LIFE SCIENCES INDUSTRY IS HIGHLY COMPETITIVE AND SUBJECT TO RAPID
TECHNOLOGICAL CHANGE, AND WE MAY NOT HAVE THE RESOURCES NECESSARY TO
SUCCESSFULLY COMPETE.

We compete with companies in the United States and abroad that are engaged in
the development and production of similar products. We face competition
primarily from the following three sectors:

+  companies marketing conventional products based on traditional chemistry
   methodologies;

+  pharmaceutical companies developing their own instruments; and

+  companies marketing products based upon parallel synthesis and other
   innovative technologies.

Many of our competitors have access to greater financial, technical, research,
marketing, sales, distribution, service and other resources than we do. We face,
and will continue to face, intense competition from organizations serving the
life sciences industry that are developing or marketing competing products and
technologies. These organizations may develop products or technologies that are
superior to our products or technologies in terms of performance, cost or both.

We may need to develop new applications for our products to remain competitive.
Our present or future products could be rendered obsolete or uneconomical by
technological advances by one or more of our current or future competitors. In
addition, the introduction or announcement of new products by us or by others
could result in a delay of or decrease in sales of existing products, as
customers

- --------------------------------------------------------------------------------
 12
<PAGE>   15
RISK FACTORS
- --------------------------------------------------------------------------------

evaluate these new products. Our future success will depend on our ability to
compete effectively against current technology as well as to respond effectively
to technological advances.

OUR SUCCESS WILL DEPEND PARTLY ON OUR ABILITY TO OPERATE WITHOUT INFRINGING ON
OR MISAPPROPRIATING THE PROPRIETARY RIGHTS OF OTHERS.

We may be sued for infringing on the intellectual property rights of others. In
addition, we may find it necessary, if threatened, to initiate a lawsuit seeking
a declaration from a court that we do not infringe on the proprietary rights of
others or that their rights are invalid or unenforceable. If we do not prevail
in any litigation, in addition to any damages we might have to pay, we could be
required to stop the infringing activity or obtain a license. Any required
license may not be available to us on acceptable terms, or at all. In addition,
some licenses may be nonexclusive, and therefore, our competitors may have
access to the technology licensed to us. If we fail to obtain a required license
or are unable to design around a patent, we may be unable to sell some of our
products, which could harm our ability to compete and result in a decline in our
revenues.

THE INTELLECTUAL PROPERTY RIGHTS WE RELY UPON TO PROTECT THE TECHNOLOGY
UNDERLYING OUR PRODUCTS MAY NOT BE ADEQUATE, WHICH COULD ENABLE THIRD PARTIES TO
USE OUR TECHNOLOGY OR VERY SIMILAR TECHNOLOGY AND COULD REDUCE OUR ABILITY TO
COMPETE IN THE MARKET.

Our success will depend on our ability to obtain and enforce patents on our
technology and to protect our trade secrets. The patent position of companies
like ours generally is highly uncertain and involves complex legal and factual
questions. Any patents we own may not afford meaningful protection for our
technology and products. Others may challenge our patents and, as a result, our
patents could be narrowed, invalidated or rendered unenforceable. In addition,
our current and future patent applications may not result in the issuance of
patents in the United States or foreign countries. There is a substantial
backlog of patent applications at the U.S. Patent and Trademark Office, and the
approval or rejection of patent applications may take several years. Moreover,
competitors may develop products similar to ours that are not covered by our
patents.

We try to protect our unpatented trade secrets by requiring our employees,
consultants and advisors to execute confidentiality agreements. However, we
cannot guarantee that these agreements will provide us with adequate protection
against improper use or disclosure of our trade secrets. In addition, in some
situations, these agreements may conflict with, or be subject to, the rights of
third parties with whom our employees, consultants or advisors have prior
employment or consulting relationships. Further, others may independently
develop substantially equivalent proprietary information and techniques, or
otherwise gain access to our trade secrets. If we are unable to protect our
proprietary information and techniques, our ability to exclude certain
competitors from the market will be limited.

WE MAY BE INVOLVED IN LAWSUITS TO PROTECT OR ENFORCE OUR INTELLECTUAL PROPERTY
RIGHTS, WHICH MAY BE EXPENSIVE. IF WE LOSE SUCH LAWSUITS, WE MAY LOSE THE
BENEFIT OF SOME OF OUR INTELLECTUAL PROPERTY RIGHTS, THE LOSS OF WHICH MAY
INHIBIT OR REMOVE OUR ABILITY TO EXCLUDE CERTAIN COMPETITORS FROM THE MARKET.

In order to protect or enforce our patent rights, we may have to initiate legal
proceedings against third parties, such as infringement suits or interference
proceedings. We may also provoke third parties to assert claims against us,
which could invalidate our patents or result in damages to us. Intellectual
property litigation is costly, and, even if we prevail, the cost of such
litigation could affect our profitability. In addition, litigation is time
consuming and could divert management attention and resources away from our
business.

RISK FACTORS
- --------------------------------------------------------------------------------

RISKS RELATED TO THIS OFFERING

OUR STOCK PRICE COULD BE VOLATILE, AND YOUR INVESTMENT COULD SUFFER A DECLINE IN
VALUE.

The trading price of our common stock is likely to be highly volatile and could
be subject to wide fluctuations in price in response to various factors, many of
which are beyond our control, including:

+  actual or anticipated variations in quarterly operating results;

+  failure to achieve, or changes in, financial estimates by securities
   analysts;

+  announcements of new products or services or technological innovations by us
   or our competitors;

+  conditions or trends in the pharmaceutical, biotechnology and life science
   industries;

+  announcements by us of significant acquisitions, strategic partnerships,
   joint ventures or capital commitments;

+  additions or departures of key personnel;

+  sales of our common stock; and

+  developments regarding our patents or other intellectual property or that of
   our competitors.

In addition, the stock market in general, and the Nasdaq National Market and the
market for technology companies in particular, have experienced significant
price and volume fluctuations that have often been unrelated or disproportionate
to the operating performance of those companies. Further, there has been
particular volatility in the market prices of securities of life science
companies. These broad market and industry factors may seriously harm the market
price of our common stock, regardless of our operating performance. In the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has often been instituted. A securities class
action suit against us could result in substantial costs, potential liabilities
and the diversion of management's attention and resources.

THERE MAY NOT BE AN ACTIVE, LIQUID TRADING MARKET FOR OUR COMMON STOCK.

Prior to this offering, there has been no public market for our common stock. An
active trading market for our common stock may not develop following this
offering. You may not be able to sell your shares quickly or at the market price
if trading in our stock is not active. The initial public offering price will be
determined by negotiations between us and representatives of the underwriters
based upon a number of factors. The initial public offering price may not be
indicative of prices that will prevail in the trading market. See "Underwriting"
for more information regarding the factors considered in setting the initial
public offering price.

OUR PRINCIPAL STOCKHOLDERS, DIRECTORS AND EXECUTIVE OFFICERS WILL OWN
APPROXIMATELY     % OF OUR COMMON STOCK, WHICH MAY PREVENT NEW INVESTORS FROM
INFLUENCING CORPORATE DECISIONS.

After this offering, our stockholders who currently own over 5% of our common
stock, our directors and executive officers will beneficially own approximately
     % of our outstanding common stock or      % if the underwriters exercise
their over-allotment option in full. These stockholders will be able to exercise
significant influence over all matters requiring stockholder approval, including
the election of directors and the approval of significant corporate
transactions. This concentration of ownership may also delay or prevent a change
in control of us even if beneficial to our other stockholders. See "Principal
stockholders" for additional information on the concentration of ownership of

RISK FACTORS
- --------------------------------------------------------------------------------

THE LARGE NUMBER OF SHARES OF OUR COMMON STOCK ELIGIBLE FOR PUBLIC SALE AFTER
THIS OFFERING COULD CAUSE OUR STOCK PRICE TO DECLINE.

The market price of our common stock could decline as a result of sales of
substantial amounts of our common stock in the public market after the closing
of this offering, or the perception that these sales could occur. In addition,
these factors could make it more difficult for us to raise funds through future
offerings of common stock. There will be           shares of common stock
outstanding immediately after this offering, or           shares if the
underwriters exercise their over-allotment option in full, based on the number
of shares outstanding at March 31, 2000. All of the shares sold in the offering
will be freely transferable without restriction or further registration under
the Securities Act, except for any shares purchased by our "affiliates," as
defined in Rule 144 of the Securities Act. The remaining shares of common stock
outstanding will be "restricted securities" as defined in Rule 144. These shares
may be sold in the future without registration under the Securities Act to the
extent permitted by Rule 144 or other exemptions under the Securities Act.

After this offering, we intend to register approximately           shares of
common stock that are reserved for issuance upon exercise of options granted
under our stock option plan. Once we register these shares, they can be sold in
the public market upon issuance, subject to restrictions under the securities
laws applicable to resales by affiliates. See "Shares eligible for future sale."

YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.

The initial public offering price of our common stock is expected to be
substantially higher than the net tangible book value per share of our common
stock. Therefore, if you purchase shares of our common stock in this offering,
you will incur immediate dilution of approximately $          in the pro forma
net tangible book value per share of our common stock from the price per share
that you pay for our common stock (based upon an assumed initial public offering
price of $     per share). If the holders of our outstanding options or warrants
exercise those options or warrants at prices below the initial public offering
price, you will incur further dilution.

BECAUSE IT IS UNLIKELY THAT WE WILL EVER PAY DIVIDENDS, YOU WILL ONLY BE ABLE TO
BENEFIT FROM HOLDING OUR STOCK IF THE STOCK PRICE APPRECIATES.

We have never paid cash dividends on our capital stock and do not anticipate
paying any cash dividends in the foreseeable future. Additionally, under our
outstanding credit agreements we are prohibited from declaring or paying
dividends without the consent of our lender, Comdisco, Inc.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER AND BYLAWS AND UNDER DELAWARE LAW COULD
MAKE A THIRD-PARTY ACQUISITION OF US DIFFICULT.

Our certificate of incorporation and bylaws contain provisions that could make
it more difficult for a third party to acquire us, even if doing so might be
deemed beneficial by our stockholders. These provisions could limit the price
that investors might be willing to pay in the future for shares of our common
stock. We are also subject to certain provisions of Delaware law that could
delay, deter or prevent a change in control of us. See "Description of capital
stock -- Anti-takeover effects of provisions of the certificate of
incorporation, bylaws and Delaware law."

Forward-looking information

Some of the statements that we make under "Prospectus summary," "Risk factors,"
"Management's discussion and analysis of financial condition and results of
operations," "Business" and elsewhere in this prospectus constitute
forward-looking statements. These statements relate to future events or our
future financial performance and involve known and unknown risks, uncertainties
and other factors that may cause our or our industry's actual results, levels of
activity, performance or achievements to be materially different from those
expressed or implied by any of our forward-looking statements. Some of these
factors are listed under "Risk factors" and elsewhere in this prospectus. In
some cases, you can identify forward-looking statements by terminology such as
"may," "will," "should," "expects," "plans," "anticipates," "intends,"
"believes," "estimates," "predicts," "potential" or "continue" or the negative
of these terms or other comparable terminology. These statements are only
predictions. Actual events or results may differ materially. Moreover, neither
we nor any other person assumes responsibility for the accuracy and completeness
of those statements. We are under no duty to update any of the forward-looking
statements after the date of this prospectus to conform them to actual results.

Use of proceeds

We estimate that the net proceeds from the sale of the shares of common stock we
are offering will be approximately $          million at an assumed initial
public offering price of $     per share after deducting the underwriting
discounts and commissions and estimated offering expenses. If the underwriters
exercise their over-allotment option in full, we estimate that the net proceeds
will be approximately $          million.

We currently intend to use the net proceeds of this offering to fund expansion
of our operations, including continued development and manufacturing of existing
products and research and development of additional products, expanding our
facilities to be able to meet the needs of our growing business, repayment of
debt and for other working capital and general corporate purposes. Although we
have no current plans, agreements or commitments with respect to any
acquisition, we may, if the opportunity arises, use a portion of the net
proceeds to acquire or invest in products, technologies or companies. The timing
and amount of our actual expenditures will be based on many factors, including
cash flows from operations and the growth of our business. Our management may
spend the proceeds from this offering in ways that the stockholders may not deem
desirable.

Until we use the net proceeds of this offering for the above purposes, we intend
to invest the funds in short-term, investment grade, interest-bearing
securities. We cannot predict whether the proceeds invested will yield a
favorable return.

Dividend policy

We have never declared or paid any cash dividends on our capital stock. We
anticipate that we will retain any earnings to support operations and to finance
the growth and development of our business. Additionally, under our outstanding
credit agreements we are prohibited from declaring dividends without the consent
of our lender, Comdisco, Inc. Therefore, we do not expect to pay cash dividends
in the foreseeable future. Any future determination relating to our dividend
policy will be made in the discretion of our board of directors and will depend
on a number of factors, including future earnings, capital requirements,
financial conditions and future prospects and other factors the board of
directors may deem relevant.

Dilution

Our pro forma net tangible book value as of March 31, 2000, was approximately
$7.7 million, or $0.54 per share. Pro forma net tangible book value per share
represents the amount of our total tangible assets less total liabilities,
divided by the number of shares of common stock outstanding after giving effect
to the automatic conversion of our preferred stock outstanding as of March 31,
2000, into 11,339,268 shares of our common stock.

Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of our
common stock in this offering and the pro forma net tangible book value per
share of our common stock immediately afterwards, after giving effect to the
sale of           shares in this offering at an assumed initial offering price
of $     per share and after deducting underwriting discounts and commissions
and offering expenses. This represents an immediate increase in pro forma net
tangible book value of $     per share to existing stockholders and an immediate
dilution in pro forma net tangible book value of $     per share to new
investors. The following table illustrates this per share dilution:

The following table summarizes, on a pro forma basis as of March 31, 2000, after

</TABLE>

After this offering and assuming the exercise in full of all options and
warrants outstanding and exercisable as of March 31, 2000, the average price per
share of existing stockholders would be reduced by $     per share to be $
per share.

After this offering and assuming the exercise in full of all options and
warrants outstanding and exercisable as of March 31, 2000, our pro forma net
tangible book value per share as of March 31, 2000 would be $     per share,
representing an immediate increase in net tangible book value of $     per share
to existing stockholders and an immediate dilution in net tangible book value of
$     per share to new investors.

If the underwriters exercise their over-allotment option in full, the following
will occur:

+  the percentage of shares of our common stock held by existing stockholders
   will decrease to approximately      % of the total number of shares of our
   common stock outstanding after this offering;

+  the number of shares of our common stock held by new public investors will
   increase to           , or approximately      % of the total number of shares
   of our common stock outstanding after this offering; and

+  our pro forma net tangible book value will increase to $     per share to
   existing stockholders and our pro forma net tangible book value will be
   diluted by $     per share to new investors.

Management's discussion and analysis of financial condition
and results of operations

The following discussion of our financial condition and results of operations
should be read in conjunction with the financial statements and the notes to
those statements included elsewhere in this prospectus. This discussion may
contain forward-looking statements that involve risks and uncertainties. As a
result of many factors, such as those set forth under "Risk factors" and
elsewhere in this prospectus, our actual results may differ materially from
those anticipated in these forward-looking statements.

Since our inception, we have incurred significant losses and, as of March 31,
2000, we had an accumulated deficit of $28.9 million. We anticipate incurring
additional losses, which may increase, for the foreseeable future.

We derive revenues primarily from the sale of our instrument products. We
commenced commercial shipment of our first generation instrument, the Nautilus,
in 1996, the Quest product line in 1997, the Trident product line in 1998 and
the Surveyor and the Endeavor in 2000. Revenue from sales of our instrument
products is recognized when delivery and installation of the product is
complete. We also derive revenues from the sale of reagents and other instrument
related consumables.

Our expenses have consisted primarily of costs incurred in research and
development, manufacturing and general and administrative costs associated with
our operations, and the expansion of our sales and marketing organization. We
expect our research and development expenses to increase in the future as we
continue to develop our products. Our selling and marketing expenses are
expected to increase as we continue to expand the geographic coverage of our
direct sales and support organization. Our general and administrative expenses
are expected to increase as we expand our facilities and assume the obligations
of a public reporting company.

We have recorded deferred stock compensation in connection with the grant of
stock options to employees. Deferred stock compensation is the difference
between the deemed fair value of our common stock for financial reporting
purposes on the date such options were granted and their exercise price. We have
also recorded stock compensation for options granted to consultants in
accordance with Statement of Financial Accounting Standards No. 123. The options
granted to consultants are periodically remeasured as they vest, in accordance
with Emerging Issues Task Force No. 96-18.

We recorded deferred stock compensation of approximately $3.8 million in the
year ended December 31, 1999 and approximately $540,000 in the period ended
March 31, 2000. These amounts were recorded as a component of stockholders'
equity and are being amortized as charges to operations over the vesting periods
of the options, generally four years, using the graded vesting method. We
recorded amortization of deferred stock compensation of approximately $653,000
in the year ended December 31, 1999 and approximately $499,000 in the period
ended March 31, 2000. For options granted to employees through March 31, 2000,
we expect to record amortization of deferred stock compensation as follows:
approximately $1.2 million for the remainder of 2000; approximately $975,000 in
2001; approximately $563,000 in 2002; approximately $287,000 in 2003;
approximately $80,000 in 2004; and approximately $1,000 in 2005. We may record
additional deferred stock compensation expense if we grant additional options
below the deemed fair value of our common stock.

We have a limited history of operations. We anticipate that our quarterly
results of operations will fluctuate for the foreseeable future due to several
factors, including market evaluation and acceptance

of our current and new products, which may result in a lengthy sales cycle,
patent conflicts, the introduction of new products by our competitors, the
timing and extent of our research and development efforts, and the timing of
significant orders. Our limited history makes accurate predictions of future
operations difficult.

RESULTS OF OPERATIONS

QUARTERS ENDED MARCH 31, 2000 AND 1999

NET SALES
Net sales in the first quarter of 2000 increased to $3.6 million from $3.0
million in the same period of 1999. The increase was due to slightly higher
sales in both instruments and chemistry products. The increase in instrument
sales was due to higher sales of the Quest product line, a full quarter's impact
of our FirstMate, offset by lower sales of Trident related products. Also in the
first quarter of 2000, we recognized revenue from the sale of our first unit of
our Surveyor product.

COST OF SALES
Cost of sales increased to $1.4 million in the first quarter of 2000 from $1.2
million in the first quarter of 1999. The increase was primarily due to higher
sales volume.

RESEARCH AND DEVELOPMENT EXPENSES
Research and development expenses increased to $1.3 million in the first quarter
of 2000 from $1.0 million in the same period of 1999. These expenses include
salaries and related costs of research and development personnel as well as the
cost of parts and supplies associated with research and development projects.
Personnel levels remained relatively constant in both periods and the increase
of $300,000 was primarily attributable to amortization of the deferred stock
compensation recorded in 1999 and the first quarter of 2000.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
Selling, general and administrative expenses increased to $2.9 million in the
first quarter of 2000 from $2.0 million in the first quarter of 1999. These
expenses consist primarily of salaries and related costs for executive, sales
and marketing, finance and other administrative personnel and the cost of
facilities. The increase was attributable to the further expansion of our direct
sales force in the United States and Europe and also due to amortization of the
deferred stock compensation recorded in 1999 and the first quarter of 2000.

INTEREST AND OTHER INCOME (EXPENSES), NET
Interest and other income (expenses), net, increased to $10,000 in the first
quarter of 2000 from $(172,000) in the same period of 1999. The increase was
primarily due to interest income generated from the investment of proceeds of
our Series D preferred stock financing in May 1999.

YEARS ENDED DECEMBER 31, 1999 AND 1998

NET SALES
Net sales in 1999 were $10.6 million versus $12.1 million in 1998. The decrease
in our net sales is primarily the result of lower Quest sales, the
discontinuation of our first product, the Nautilus, in the first quarter of
1999, and a change in our product sales strategy to include installation in the
selling

price of certain instrument products, resulting in a delay in revenue
recognition, partially offset by higher sales for the Trident product line.

COST OF SALES
Cost of sales decreased to $4.7 million in 1999 from $5.6 million in 1998. This
decrease was primarily due to lower sales volume.

RESEARCH AND DEVELOPMENT EXPENSES
Research and development expenses decreased to $4.2 million in 1999 from $4.9
million in 1998. These expenses include salaries and related costs of research
and development personnel as well as the costs of parts and supplies associated
with research and development projects. Personnel levels and related expenses
remained relatively constant during both periods. The $700,000 decrease in
research and development expenses is primarily attributable to the timing of the
cost of parts and components associated with specific research and development
projects. During 1998, the major focus of the research and development group was
on the Trident product line. During 1999, the research and development group
focused on several projects which were at earlier stages of development. This
resulted in a decrease in parts and supplies associated with the research.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
Selling, general and administrative expenses increased to $9.1 million in 1999
from $7.1 million in 1998. These expenses consist primarily of salaries and
related costs for executive, sales and marketing, finance and other
administrative personnel and the costs of facilities. The increase was
attributable to further expansion of our direct sales force in the United States
and Europe and the recruitment and placement of a general manager for our
Japanese subsidiary during 1999.

INTEREST AND OTHER INCOME (EXPENSES), NET
Net interest expense increased to $167,000 in 1999 from $94,000 in 1998. The
increase was primarily attributable to the interest expense for the additional
debt incurred on our equipment and accounts receivable financing loans.

INCOME TAXES
As of December 31, 1999, we had federal net operating loss and research credit
carryforwards of approximately $23.0 million and $600,000, respectively, which
expire on various dates between 2010 and 2019. We also had state net operating
loss carryforwards of approximately $7.4 million and research credit
carryforwards of approximately $500,000. The state net operating loss will
expire on various dates between 2003 and 2004. The state research credits will
not expire.

Utilization of the net operating losses may be subject to a substantial annual
limitation due to the ownership change limitations provided by the Internal
Revenue Code of 1986 and similar state provisions. The annual limitation may
result in the expiration of net operating losses and credits before utilization.

YEARS ENDED DECEMBER 31, 1998 AND 1997

NET SALES
Net sales increased to $12.1 million in 1998 from $5.8 million in 1997. The
increase in revenue is primarily attributable to increased U.S. sales of our
Quest product line, which was introduced in the last quarter of 1997.

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

COST OF SALES
Cost of sales increased to $5.6 million in 1998 from $3.2 million in 1997. The
increase is attributed to the increase in product sales over the period.

RESEARCH AND DEVELOPMENT EXPENSES
Research and development expenses increased to $4.9 million in 1998 from $4.3
million in 1997. These expenses include salaries and related costs of research
and development personnel as well as the costs of parts and supplies associated
with research and development projects. The increase in research and development
expense is attributable to the timing of the cost of parts and components
associated with specific research and development projects. During 1998 there
was an increase in the parts and supplies associated with the research and
development projects. Personnel levels and related expenses remained constant
during both periods.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
Selling, general and administrative expenses increased to $7.1 million in 1998
from $4.8 million in 1997. These expenses consist primarily of salaries and
related costs for executive, sales and marketing, finance and other
administrative personnel and the costs of facilities. The increase was
attributable to establishment of our wholly owned subsidiary in Japan, a
management change in our European office, and further expansion of our direct
sales force in the United States and Europe. Additionally, we introduced several
new products in 1998, which resulted in an increase in marketing activities such
as industry trade shows, advertising and collateral.

INTEREST AND OTHER INCOME (EXPENSE), NET
Interest income and other income (expense), net, was $(94,000) in 1998 compared
to $216,000 in 1997. This decrease in interest income was primarily attributable
to the utilization of funds for operations in 1998, where previously the funds
were used for investment purposes, and the interest expense associated with the
debt incurred on our equipment and accounts receivable financing.

LIQUIDITY AND CAPITAL RESOURCES

We have funded our operations principally with approximately $35 million of
private equity financings that came from a series of preferred stock offerings
from 1995 through 1999 as follows:

Each share of Series A, B, C and D preferred stock is convertible into one share
of our common stock.

In addition, we have various loan agreements with Comdisco, Inc. for loan
facilities of up to $9.5 million. Through March 31, 2000, we have drawn down
approximately $5.5 million against these facilities and we had approximately
$4.0 million available for future draw downs. The loans are secured by our
assets, subordinated to institutional creditors and bear interest at rates
ranging from 10% to 12.5%. Under the terms of certain of the loan agreements, we
are required to issue to Comdisco, Inc. warrants to purchase shares of our
Series C preferred stock upon signing of

the agreement and certain draw down limits. At March 31, 2000, we had issued to
Comdisco, Inc. warrants to purchase an aggregate of 91,665 shares of our Series
C preferred stock.

Net cash used in operating activities was $5.9 million in 1997, $7.3 million in
1998, $5.4 million in 1999 and $1.3 million in the three months ended March 31,
2000. Cash used in operating activities was attributable primarily to net
losses, after adjustments for non-cash items, and working capital requirements.

Net cash provided by (used in) investing activities was $(1.3 million) in 1997,
$567,000 in 1998, $(6.8 million) in 1999 and $655,000 in the three months ended
March 31, 2000. Our investing activities consisted principally of capital
expenditures and purchases and sales of our short-term investments.

Net cash provided by (used in) financing activities was $7.2 million in 1997,
$2.3 million in 1998, $14.9 million in 1999 and $(339,000) in the three months
ended March 31, 2000. Our financing activities consisted principally of
draw-downs on our loan facilities to finance our operations, repayments of our
loan and capital lease obligations and proceeds from the sale of our convertible
preferred stock.

We expect to have negative cash flow from operations through at least 2000.
However, we expect to incur increasing development expenses, as well as expenses
for additional personnel for production and commercialization efforts, and we
may never generate positive cash flows. Our future capital requirements depend
on a number of factors, including market acceptance of our products, the
resources we devote to developing and supporting our products, continued
progress of our research and development of potential products, the need to
acquire licenses to new technology and the availability of other financing. We
believe that our current cash balances, together with the net proceeds of this
offering and revenue to be derived from product sales and research and
development collaborations will be sufficient to fund our operations at least
through the next 24 months. To the extent our capital resources are insufficient
to meet future capital requirements, we will need to raise additional capital or
incur indebtedness to fund our operations. There can be no assurance that
additional debt or equity financing will be available on acceptable terms, if at
all. If adequate funds are not available, we may be required to delay, reduce
the scope of, or eliminate, our operations or obtain funds through arrangements
with collaborative partners or others that may require us to relinquish rights
to certain technologies or products that we might otherwise seek to retain.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK
Our exposure to interest rate risk is related to our investment portfolio and
our borrowings. Fixed rate investments and borrowings may have their fair market
value adversely impacted from changes in interest rates. Floating rate
investments may produce less income than expected if interest rates fall, and
floating rate borrowings will lead to additional interest expense if interest
rates increase. Due in part to these factors, our future investment income may
fall short of expectations, and our interest expense may be above our
expectations due to changes in U.S. interest rates. Further, we may suffer
losses in investment principal if we are forced to sell securities that have
declined in market value due to changes in interest rates.

We invest our excess cash in debt instruments of the U.S. government and its
agencies, and in debt instruments of high quality corporate issuers. Due to the
short term nature of these investments, we have assessed that there is no
material exposure to interest rate risk arising from our investments.

We enter into loan arrangements with financial institutions when available on
favorable terms. At March 31, 2000, we had institutional borrowings of $4.1
million outstanding, which bear interest at

- --------------------------------------------------------------------------------
 26
<PAGE>   29
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
- --------------------------------------------------------------------------------

rates ranging from 10% to 12.5%. We have determined that there is no material
exposure to interest rate risk arising from these borrowings. Under the terms of
these loan arrangements, the Company is prohibited from declaring dividends
without the consent of the financial institution.

FOREIGN CURRENCY RISK
As we have operations and sales outside of the United States, our financial
results can be affected by changes in foreign currency exchange rates or weak
economic conditions in the foreign markets in which we operate. To date, our
foreign operations and sales have not been significant to our results of
operations and financial condition.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting No. 133, Accounting for Derivative Instruments and
Hedging Activities ("SFAS 133"). SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income. In June 1999, FASB issued Statement of Financial
Accounting Standards No. 137, which defers the effective date of SFAS No. 133 to
years beginning after June 15, 2000. We do not expect that the adoption of SFAS
No. 133 will have a material impact on results and operations or financial
condition.

In December 1999, the Securities and Exchange Commission released Staff
Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, which
provides guidance on the revenue recognition. We have adopted this guidance in
our consolidated financial statements.

Business

OVERVIEW

We are a pioneer in the development, manufacturing and marketing of innovative
products that enable chemists to use high speed parallel synthesis for the
development of new drugs. Parallel synthesis is a process by which chemists
create multiple compounds. Our products include a variety of parallel chemical
synthesizers and reagents. Our products enable chemists to increase their
productivity, accelerate the drug development process and reduce costs.
Currently, our products are used for chemistry development by chemists in the
pharmaceutical, biotechnology, life sciences and chemical research fields
worldwide.

Advances in the drug discovery process have resulted in a significant increase
in the number of new tools and targets for the development of new drugs, or drug
targets. However, unlike drug discovery, drug development lacks the
technological advances and automation that would allow efficient utilization of
new targets. As a result, many companies are seeking innovative and
cost-effective tools and technologies that would be used to explore the
increasing number of targets for the potential development of new drugs. Our
instruments enable parallel synthesis and automate many of the most
labor-intensive steps of chemistry development. Through automation, chemists are
able to perform multiple experiments under a variety of conditions in a fraction
of the time it would take to perform the same experiments using traditional
chemistry development methods. We believe that our products will enable
companies to develop new drugs in a more productive, faster and more
cost-effective manner than by using traditional chemistry development methods.
Therefore companies, through the use of our products, may capitalize on the
wealth of potential new drug targets being generated by the drug discovery
process.

We began marketing our first product in 1996. Currently, we have eight
instrument product offerings and more than 40 reagent product offerings. Through
March 31, 2000, we have sold our products to more than 545 customers in the
pharmaceutical, biotechnology, life sciences and chemical research industries
and have placed more than 640 instruments worldwide. In addition, we have a
track record of quickly and effectively developing solutions to our customers'
problems. In order to ensure that our products meet the specific needs of
chemists throughout the research community, we have formed formal consortia and
informal relationships with teams of industry leaders and academic institutions
for each of our instruments released to date. Through this process we have
developed innovative products that have extensive customer input, validation and
testing prior to commercial introduction.

INDUSTRY

BACKGROUND

The life sciences research industry is undergoing fundamental change resulting
principally from the explosive growth in gene discovery and the increasing
demand for greater efficiency in the drug discovery and development process.
Industry experts estimate that in the year 2000 the life sciences research
industry will spend more than $70 billion on drug discovery research and
development. Advances in genomics, combinatorial chemistry and high throughput
screening have significantly enhanced the discovery process. Genomics, the
mapping of the human DNA sequence and the study of the role genes play in
disease, is creating an unprecedented wealth of information concerning potential
drug targets. Industry sources estimate that sequencing of the human genome will
provide an estimated 3,000 to 10,000 relevant new drug targets over the next ten
years, compared to the approximately 500

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

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

targets that have been explored thus far. Combinatorial chemistry is the rapid
synthesis of large collections of potential drug candidates. Through
combinatorial chemistry, chemists can generate chemical collections, or
libraries, consisting of millions of compounds that researchers can screen
against drug targets through the use of high throughput screening technologies.
Chemists have been able to make these advances in drug discovery by using new
tools that simplify, automate and accelerate the drug discovery process. Through
widespread use of these tools chemists are discovering a large number of new
drug candidates that are ready for the drug development process. However, the
pharmaceutical industry does not have sufficient tools and resources to fully
exploit the opportunities presented by advances in drug discovery due to the
technological limitations of traditional drug development, or chemistry
development.

DRUG DISCOVERY AND DEVELOPMENT

Although the drug discovery and development process involves a number of steps,
it can best be understood in the context of two phases:

+  DISCOVERY PHASE. Discovery is the process by which drug targets identified
   through biology, including genomics and proteomics, the study of protein
   function, are developed into biological screens by chemists. Then, the
   millions of compounds produced by combinatorial chemistry are tested using
   high throughput biological screens to identify possible drug candidates.

+  DEVELOPMENT PHASE. Development is the process in which pharmacological,
   pharmacokinetic and safety properties of a drug are optimized by chemists for
   human testing and approval. Pharmacological properties are the measure of a
   drug's potency with respect to a specific drug target. The pharmacokinetic
   properties of a drug are the extent to which the drug remains available in
   the body for interaction with the target. Safety is a measure of a drug's
   toxicity to humans. The development phase can be further broken down into
   three stages:

     +  LEAD OPTIMIZATION. Lead optimization is the process used by chemists to
        evaluate the hundreds of drug candidates that may emerge from the
        discovery phase. Chemists perform successive rounds of chemical
        syntheses to create numerous variants of the drug candidates to find
        compounds likely to have appropriate drug properties. Chemists then
        optimize the compounds for their biological potency, thus creating lead
        compounds.

     +  PRE-CLINICAL DEVELOPMENT. Pre-clinical development is the process by
        which chemists further refine a limited number of lead compounds into
        clinical drug candidates by application of additional chemistry
        methodologies. During this process, chemists make relatively small
        changes to the compounds in order to optimize their safety and
        pharmacokinetic properties.

     +  CLINICAL DEVELOPMENT. Clinical development is the process in which
        chemists test clinical candidates in humans to demonstrate their safety
        and effectiveness, or efficacy. The successful outcome of clinical
        trials may result in regulatory approval to commercialize the new drug
        product. During this time period, chemists optimize the method of
        compound synthesis prior to commencement of large scale manufacturing of
        the drug.

TRADITIONAL CHEMISTRY METHODS FOR DRUG DEVELOPMENT

Chemists typically employ traditional methods in their drug development efforts.
Utilizing traditional methods of chemical synthesis, a chemist performs a series
of chemical reactions, or transformations, until the desired compound is
obtained. Each synthetic transformation is generally achieved in a four-part
process:

SET-UP AND EXECUTION OF REACTION
The first step undertaken by a chemist using chemical synthesis is building a
reaction apparatus. Chemists often construct the apparatus using a variety of
traditional laboratory components depending on the type of chemistry they are
performing. The chemist uses the apparatus to combine chemicals, reagents and
solutions, which the chemist will often heat or cool to specified temperatures
under air and moisture-free, or inert, conditions. The chemist then monitors
reactions over time to determine reaction progress. In chemistry development,
the assembly of a specific apparatus and the periodic addition of chemicals can
often be very complicated and time-consuming depending on the complexity of the
desired reaction. In addition, although some reactions occur very quickly,
others can take hours, or even days to complete, and involve frequent
monitoring.

PRODUCT WORK-UP
The second step in chemical synthesis is product work-up by the chemist. Once
the chemist determines that a reaction has proceeded to completion, the chemist
subjects the reaction mixture to an extensive reaction work-up. During the
work-up the chemist stops the reaction and carries out an initial cleanup of the
reaction mixture prior to purification. The chemist performs a series of washes
with a variety of

- --------------------------------------------------------------------------------
 30

BUSINESS
- --------------------------------------------------------------------------------

solvents, a drying process and a filtration process during the work-up. The
chemist usually takes several hours to complete this labor-intensive work-up
process.

PRODUCT PURIFICATION
The third step in chemical synthesis is product purification by the chemist.
During this step, the chemist isolates the desired product from its starting
materials and various byproducts. Product purification is an integral step in
chemical synthesis due to the fact that impurities may interfere in the next
chemical transformation by masking a drug's potency and toxicity. Chemists
typically utilize large volumes of multiple solvents during the purification
process. This step often takes days to complete.

PRODUCT ANALYSIS
The final step in chemical synthesis is product analysis. In this step, the
chemist confirms that the desired drug has been synthesized and isolated before
submitting the compound for biological testing. Analysis requires a large amount
of data collection and is labor-intensive.

Chemists must repeat this laborious, four-step process until the desired
compound is obtained. The synthesis of a particular compound could take months
and even years to complete before researchers can determine whether the compound
has the desired drug properties.

LIMITATIONS OF EXISTING DRUG DEVELOPMENT TECHNOLOGIES

Traditional chemistry development methods have the following limitations:

+  LIMITED PRODUCTIVITY. Traditional methods are time consuming, inefficient and
   labor-intensive. Industry sources estimate that chemists currently synthesize
   an average of 100 compounds per year. Since it is not economically feasible
   for pharmaceutical companies to increase chemistry headcount to the extent
   necessary to take advantage of the thousands of expected drug targets, we
   believe that throughput in the development phase must increase dramatically.

+  LONG DRUG DEVELOPMENT TIMELINES. Traditional methods require chemists to
   synthesize compounds one at a time in an inefficient, sequential process.
   This results in long drug development timelines, which delay product
   commercialization and reduce the commercial value of the exclusivity period
   provided by patent protection.

+  HIGH COST. Traditional methods are expensive due to the time and labor
   required of a chemist to produce a single compound. In addition, companies
   utilizing the traditional methods incur the costs associated with the high
   volumes of solvents and chemicals utilized and the expense associated with
   their disposal.

+  HIGH DRUG CANDIDATE FAILURES. Traditional methods limit the number of
   compounds synthesized, which can lead to the selection of sub-optimal drug
   candidates, often resulting in drug candidate failures. These failures
   greatly increase the average length of time and cost required to bring a
   specific drug to market. If a drug candidate fails during clinical trials, a
   company must incur the time and expense of repeating all of the development
   steps or face abandoning the project altogether. The cost of a failed
   candidate increases significantly as it progresses to later stages of the
   development process.

+  LACK OF FLEXIBILITY. To date, chemists have lacked flexible tools and systems
   to easily perform the wide variety of complex experiments required for
   chemistry development. Instead, chemists have had to repeatedly assemble
   various components into complicated systems.

+  DIFFICULT TO USE. The steps required to put together an apparatus and perform
   the reaction, work-up, purification and data analysis are difficult to
   execute. Therefore, many of these complex chemistries require skilled
   chemists with many years of training.

These limitations restrict the ability of pharmaceutical companies to fully
capitalize on the large number of new drug candidates resulting from the
significant technical advances in drug discovery. In order to take advantage of
these advances, we believe that pharmaceutical and life science companies will
need to increase productivity, shorten the drug development process and reduce
costs. We believe that these objectives will only be achieved through advances
and innovations in chemistry development technologies and tools.

THE ARGONAUT SOLUTION

We design, manufacture and market instruments and reagents that increase the
productivity of chemists, thereby accelerating the drug development process. Our
products enable the rapid synthesis of a wide range of compounds at a reduced
cost. We design and develop products using extensive customer assessment,
validation and testing. We intend to promote our products as the laboratory
standard for chemists and the industry standard for companies seeking more
efficient methods of addressing their increasing drug development needs. We
believe our technology provides the following key benefits over current
chemistry development methods:

INCREASED PRODUCTIVITY
Our systems are designed to simultaneously synthesize many distinct compounds by
automating many of the labor-intensive aspects of the experiments. Our systems
allow a chemist to save significant time and effort while performing a greater
number of experiments. A chemist, using the traditional approach of performing
one reaction at a time, can create approximately 100 compounds per year. Using
our products, the same chemist can create up to 192 compounds per day.

REDUCED DRUG DEVELOPMENT TIMELINES
Through parallel synthesis and automation, our products enable faster
optimization of drug candidates by producing a significantly larger number of
compounds in less time than traditional methods. By simultaneously producing
numerous variants of drug candidates, our tools provide more comprehensive
information for the management by chemists of drug development projects. Through
the use of improved data, our customers can identify and accelerate the
development of promising drug candidates, thus significantly reducing drug
development timelines.

REDUCED COSTS
Our products result in significant cost savings due to reduced labor hours and
reduced solvent usage. We believe that reactions performed in our systems versus
those performed out using traditional methods could result in significant cost
savings per compound. In addition, by synthesizing more drug candidates, our
products provide greater amounts of information and enable companies to abandon
poor drug candidates sooner, thereby eliminating the costs associated with later
stage drug failures.

IMPROVED INTELLECTUAL PROPERTY POSITIONS
Our tools can significantly increase the number of chemical compounds
synthesized. As a result, pharmaceutical companies may be able to improve their
patent and intellectual property positions by submitting more detailed claims
with their patent applications covering a wider variety of compounds.

FLEXIBILITY
Our products are flexible and can perform a wide range of chemical reactions,
from simple reactions to complex, multi-step reactions that require inert
environments. As a result, chemists are able to more easily perform complex and
difficult reactions, thereby encouraging innovation on the part of chemists.

EASE OF USE
Our systems are designed to make the labor-intensive steps of performing the
reaction, work-up, purification and data analysis faster and easier, and can be
operated with minimal training.

OUR STRATEGY

Our objective is to become the leading provider of productivity enhancing tools
for all stages of the chemistry development process. In order to achieve this
goal, we have implemented the following strategy:

FOCUS INITIALLY ON INDUSTRY LEADERS WITHIN THE PHARMACEUTICAL MARKET
We are initially focusing on the large and fast-growing sector of drug
development within the pharmaceutical market. We have targeted leading
pharmaceutical, biotechnology and life science companies as well as academic
institutions for our principal marketing efforts. We believe that these
customers provide the greatest opportunity for maximizing the use of our
products and that early adoption by these industry leaders and academic
institutions will promote wider market acceptance.

EXPAND OUR HIGH-VALUE REAGENT BUSINESS
In addition to our instruments, we develop, manufacture and market reagents and
other consumables for our products. We plan to continue to leverage our
installed base of instrument products through the sale of reagents and other
consumables to our existing customers as well as new customers. We intend to
expand our reagent business by offering additional reagent products.

CONTINUE TO ESTABLISH PRODUCT DEVELOPMENT COLLABORATIONS
We are continuing to pursue collaborations with pharmaceutical and biotechnology
companies in order to further develop and enhance our existing technology
platforms and products, as well as develop new products. For each of our
instruments released to date, we formed a consortium or collaboration with
industry leaders to define product requirements and to perform validation and
testing. We intend to follow this model in order to enhance market acceptance of
our current and future products. In addition, we intend to selectively
in-license and commercialize technology that can enhance our total product
offering.

BUILD GLOBAL CUSTOMER RELATIONSHIPS THROUGH DIRECT SALES
Our marketing approach is based on a thorough understanding of our customers'
specific chemistry needs, which we develop through the close interaction of our
direct sales and applications support personnel with our customers. We intend to
continue to expand our 41 person direct sales and applications support
organization to build long-term relationships with existing customers, gain
access to new accounts and expand into new geographic territories.

ACQUIRE COMPLEMENTARY BUSINESSES
We intend to pursue opportunities to expand our core business by acquiring
businesses that have technologies or capabilities complementary to ours. For
example, we may acquire software development expertise to capitalize on the
chemistry data flow generated by our products. In addition, we intend to explore
acquiring distribution channels in specific geographic regions to speed our
market penetration.

EXPAND INTO NEW MARKETS
We believe that our existing technologies and products can be leveraged into
additional markets. Our capabilities enable us to address the needs of a wide
range of chemistries. As the use of productivity

INSTRUMENTS

We address the broad range of chemistries required in all three stages of the
drug development phase with our current instrument product offerings. Each of
our instrument products has been designed for a specific stage of development,
although chemists often purchase our instruments to perform chemistry activities
in stages other than those for which they were initially designed.

TRIDENT PRODUCT LINE

Our Trident products are typically purchased by chemistry groups performing lead
optimization. These chemists synthesize libraries of between one thousand and
two thousand compounds that are closely related to a drug candidate identified
in the discovery process. Chemistry methodologies performed in lead optimization
are traditionally more difficult to perform than in the drug discovery phase, as
they require more inert synthesis conditions. The automation tools developed for
use in the drug discovery

phase for combinatorial synthesis are not capable of meeting the requirements of
chemists performing lead optimization. To enable the Trident to meet the
specific needs of lead optimization, we formed a product development consortium
compromised of eight pharmaceutical companies. As a result of this consortium,
we developed three instrument modules, the Trident Library Synthesizer, the
Trident Workstation and the Trident Sample Processing Station, the first of
which we initially commercialized in 1998. All Trident products utilize our
proprietary Reaction Cassette, which enables the automation and manual
manipulation of multi-step inert chemistry methodologies.

TRIDENT LIBRARY SYNTHESIZER

The Trident Library Synthesizer is a fully automated synthesizer that chemists
can use to produce up to 192 individual compounds simultaneously. The Trident
Library Synthesizer integrates up to four Reaction Cassettes with motors,
heaters and liquid dispensers, or fluidics, and software on a WindowsNT
computer. Since its initial commercial shipment in 1998, we have updated the
system periodically to broaden its range of chemistry capabilities. In our most
recent software update, we enhanced the system with the capability of performing
four independent chemistries, one in each of the four Reaction Cassettes, which
allows four chemists to use the instrument simultaneously.

TRIDENT WORKSTATION

The Trident Workstation is a scalable, semi-automated personal bench-top system
that utilizes a single Reaction Cassette. The Trident workstation is well suited
for the development of new chemistry methodologies, which is the most critical
path used by chemists in producing lead optimization libraries. Using the
Trident Workstation, our customers can develop and validate methodologies in the
Reaction Cassette prior to performing them on the Trident Library Synthesizer.

TRIDENT SAMPLE PROCESSING STATION

The Trident Sample Processing Station is an automated robotic platform that
utilizes the Reaction Cassette to perform work-up and purification. Often these
methodologies do not require an inert or temperature controlled environment and
therefore are more efficiently performed by chemists on a different instrument.
Some of our customers have purchased the Trident Sample Processing Station and
the Trident Workstation as an entry-level system to provide their chemists with
a cost effective solution for lead optimization.

QUEST PRODUCT LINE

The Quests are primarily purchased by our customers for pre-clinical
applications, where the goal is to refine drug candidates identified during lead
optimization. Chemists refine lead compounds by synthesizing a small library,
typically consisting of between ten and 20 compounds, testing the compounds for
drug characteristics, and based upon the tests, synthesizing another library of
compounds to start the next iteration. The Quest product line provides a
personal synthesis tool that chemists can use to perform a broad range of
chemistry methodologies, reduces the amount of laboratory space required, and is
cost effective for use by most pre-clinical groups.

The Quest product line is comprised of the Quest 210, Quest 205 and FirstMate,
all of which use our proprietary vertical mixing system. Vertical mixing is a
means chemists can use to efficiently mix reaction solutions by moving a Teflon
encapsulated magnet vertically through a solution. This mixing method offers
chemists several benefits over the traditional means of spinning a magnet in
mixtures: it can mix a broader range of viscosities and more readily mix solid
reagents that must be suspended in order for the reactions to occur. To enable
the Quest 210 to meet the specific needs of pre-clinical development, we
developed it as part of a collaboration. We initially shipped the Quest 210 in
1997.

                                                                              35
<PAGE>   38
BUSINESS
- --------------------------------------------------------------------------------

In addition, we developed the Quest 205 as part of a consortium. We initially
shipped the Quest 205 in 1998.

QUEST 210 AND QUEST 205

The Quest 210 and Quest 205 are similar systems that utilize our unique Teflon
reactor, which provides an inert reactor environment that allows chemist to view
the reaction mixtures. Each system has automated heating, cooling, mixing and
fluidics. The two systems differ by the number and volume of the reactors; the
Quest 210 has 20 ten-milliliter reactors and the Quest 205 has ten
100-milliliter reactors.

FIRSTMATE
Our most recent addition to the Quest product line is the FirstMate, which we
initially shipped in 1999. FirstMate is an entry-level, manual parallel
synthesizer, which utilizes existing laboratory equipment and glassware.
Chemists use the FirstMate for all three stages of drug development. We
developed the FirstMate for those chemists and academicians who desire a
low-cost, entry-level system.

SURVEYOR AND ENDEAVOR

The Surveyor and Endeavor are instruments we developed specifically for
synthesis requirements in clinical development, where the chemists' goal is to
maximize yield and purity prior to commencement of large scale manufacturing.
This activity is called process optimization and is a form of parallel
synthesis. Process optimization involves the chemist making the same compound in
an iterative manner by varying the synthesis conditions such as the reactants
and/or temperature, and allowing periodic sampling and analysis of the mixture
for yield and purity.

SURVEYOR
The Surveyor is a fully automated ten-reactor synthesizer that allows the
chemist to vary the synthesis conditions in each reactor. In addition, the
Surveyor automates the tedious activity of mixture sampling and analysis. The
Surveyor utilizes the Quest Teflon reactor and vertical mixing system and the
Trident software. We developed the Surveyor as part of a consortium of five
pharmaceutical companies, in order to meet the needs of clinical development. We
initially shipped the Surveyor in 2000.

ENDEAVOR
The Endeavor is a semi-automated, parallel, high pressure reactor system
designed for reactions requiring greater than standard atmospheric pressures and
gas-phase reagents, such as hydrogen. With the Endeavor, a chemist can perform
eight simultaneous reactions. We initially shipped the Endeavor in 2000.

REAGENTS

Our reagents are used by chemists to perform a broad range of chemistry
methodologies in lead optimization and pre-clinical development and can be used
in conjunction with our instruments or independently. The primary benefit of our
reagents is that they allow chemists to perform easy work-up and purification of
the reaction mixture to obtain the desired compounds by a simple filtration
process. Chemists can automate the filtration process using our instruments and
therefore achieve higher productivity by reducing the time spent manually
processing reaction mixtures.

ARGOGEL AND ARGOPORE
Chemists typically use our ArgoGel and ArgoPore reagent products to perform lead
optimization. To overcome the limitation of traditional reagents, we formed a
product development consortium consisting of four pharmaceutical companies. We
currently offer nine distinct products in each of the ArgoGel and ArgoPore
product lines. In addition we offer nine other basic reagent products. We
initially shipped these reagents in 1996.

POLYMER REAGENTS AND SOLUTION PHASE TOOLBOX
Our Polymer Reagents and Solution Phase Toolbox products are used primarily by
chemists during pre-clinical development. These chemists synthesize much smaller
numbers of compounds than chemists synthesize during lead optimization and these
chemists are more likely to use traditional synthesis methodologies. Both the
Polymer Reagents and Solution Phase Toolbox are new technologies, which allows
chemists to accelerate the synthesis, work-up and purification of traditional
synthesis methods. We tailor our polymer reagents to permit chemists to perform
a wide variety of important synthetic reactions. The Solution Phase Toolbox is a
series of prepackaged polymers that are used by chemists performing traditional
work-ups and purification processes. We currently offer nine distinct Polymer
Reagents and six distinct Solution Phase Toolbox products. We initially shipped
these products in 1998.

PRODUCT DEVELOPMENT STRATEGY

Our product development strategy is to combine our expertise in chemistry and
engineering with an understanding of market needs to rapidly design and launch
products that fulfill these needs. We have a track record of quickly and
effectively developing solutions to our customer's problems. We took fewer than
12 months to develop our last two instruments, from design initiation to
delivery of the first commercial shipment.

To understand market needs, we form product development teams with our
customers. Through this process, we have developed innovative products that have
had extensive customer input, validation and testing prior to our commercially
introducing them. We have formed product development consortia and
collaborations with our customers.

Our consortia are non-exclusive arrangements in which we bring together several
companies, typically five to seven, who share the need to solve a common
problem. We meet with consortium members on a regular basis during the product
development period to review product definition, specifications, progress,
validation and testing. We may give consortium members prototypes for use in
their research programs and we incorporate their feedback into the final
product. Members typically pay a non-refundable participation fee, which may be
credited against future purchases of the product we develop. By participating in
our consortia, and becoming familiar with the performance and operating
characteristics of the product, members can achieve a nine-month to one-year
competitive advantage on using the new technology we develop. Consortium members
often become the initial references during the product development phase and
initial customers upon our commercialization of the product. We have used the
consortium approach to develop the Trident, Quest, Surveyor and reagent
products.

Through our collaborations, we license technology that we believe has
significant potential for commercialization. Typically, our partner will have
developed and tested a concept to the prototype level. We further develop and
enhance the prototype into a commercially viable product. Our contributions
include design for manufacturing, cost reduction, safety and code compliance and
ease of use issues. Our partner is able to purchase the final product at a
substantial discount and may receive royalties on product sales. We used this
approach with the Endeavor product, which we developed in

SALES AND MARKETING

We base our sales strategy on understanding our customers' needs, recommending
solutions and ensuring successful implementation of that solution in our
customers' research laboratories. Our approach is designed to achieve customer
satisfaction and build a long-term working relationship with our customer.

As of March 31, 2000, our direct sales and marketing organization included 41
full-time employees located in North America, Europe and Japan. Our team of
professionals was comprised of senior account-oriented sales people, application
chemists, service engineers, telesales people and marketing communication
specialists who sell directly to our customers worldwide. We had 13 direct sales
professionals with an average of 12 years of experience in selling high
technology products to the scientific industry and we had ten application
chemists. In addition to their academic expertise, the industrial laboratory
experience of our sales professionals is essential to their ability to
understand our customers needs. We had seven service engineers with expertise in
both chemistry and engineering to support our customers worldwide. We had five
professional marketing communication specialists located in the United States,
Europe and Japan dedicated to providing local marketing programs. In

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

<PAGE>   41
BUSINESS
- --------------------------------------------------------------------------------

North America we had three telesales people to support the direct sales efforts
by providing lead generation, lead qualification, and consumable product sales
and service sales.

We use distributors to provide local sales and marketing in some foreign
countries, including China, Australia, Korea, Eastern Europe, Finland, Sweden,
Denmark, Italy, Spain, Israel and India. In these countries, we seek to maintain
close contact with our customers and potential customers by providing
application chemistry support and service support through our worldwide direct
sales organization. We have developed both scientific seminars and technology
transfer programs to educate and train our customers. We conduct on-site
seminars in the use of our chemistry reagents, referencing important scientific
publications and research that validate their successful usage. Typically 20 to
40 researchers at a given customer site will participate in this type of
scientific seminar.

In addition to seminars, we have developed our "Advanced Implementation
Program," a technology implementation program, designed to accelerate the
adoption of our technology within a laboratory. Our customers leverage our
experience by participating in customized classes that teach how to plan
parallel chemistry synthesis, how to use our instruments, accessories, and
chemistry reagents and how to work-up the resulting chemistry products. We
monitor our participants' success and encourage them to publish their results
internally, thereby increasing our visibility within their company.

Our web site provides technical information regarding the use of our tools for
our customers. In addition, the Internet has the potential to become a
significant distribution channel for our reagents, instrument consumables and
entry level systems. The combination of our telesales with e-commerce makes it
very easy for a customer to make routine purchases of our reagents and
consumables. We have established ArgoStore, our proprietary web site for quick,
easy and routine purchasing of our reagents and consumables. In addition, we
have entered into agreements with Chemdex, a Ventro company, and SciQuest.com to
support the purchasing of our products.

To facilitate the awareness of our products, we have arrangements with leading
academic research institutions to provide them with our products. In return our
products are validated by reputable institutions through published results in
leading scientific journals and the researchers' creation of application notes.
We also work with universities to assist them in creating and implementing
teaching laboratories that promote the scientific advantages associated with the
use of our products.

MANUFACTURING

Most of our instruments and reagents are manufactured to our specifications by a
series of qualified outside vendors. Our vendors then deliver the finished
product to us for final quality assurance testing.

INSTRUMENTS
Our instrument manufacturing staff is comprised of senior level, highly skilled
manufacturing engineers, documentation support, material procurement and
assembly support resources, which are closely integrated within our product
development group. These resources are focused on the rapid development of
manufacturing processes and methods, which are transferred to our outside
subcontractors. Our contractors are responsible for ordering all components from
qualified vendors, inspecting, stocking, assembling and testing the modules
prior to shipment to our facility. We typically qualify multiple manufacturing
subcontractors, and we develop the relevant manufacturing processes internally,
enabling us to maintain control of the manufacturing program.

REAGENTS
Our chemistry organization develops, validates, documents and initially
manufactures our reagents at our facility. During reagent development, we
qualify outside manufacturers, known as toll manufacturers, so that we can begin
outsourcing production when demand and volume increase.

INTELLECTUAL PROPERTY

As of March 31, 2000, we owned a patent portfolio of eight issued U.S. patents
and two issued foreign patents as well as several pending U.S. patent
applications. Corresponding foreign patent applications have been filed in a
number of countries. Of these issued patents, eight U.S. patents relate to the
reactor and fluidics technology incorporated into our instruments. Several of
our patent applications relate to this technology and others relate to our
reagent technologies. We intend to continue to file patent applications covering
any new inventions incorporated into our products and technologies as
appropriate. In addition, we rely upon copyright protection as well as trade
secrets, know-how and continuing technological innovation to develop and
maintain our competitive position. Our success will depend in part upon our
ability to obtain patent protection for our products and technologies, to
preserve our copyrights and trade secrets, and to operate without infringing on
the proprietary rights of third parties.

Certain of our products incorporate technology subject to patent applications
licensed to us by third parties. The related license agreements require us to
pay royalties and make other payments. These agreements are subject to
termination under certain circumstances, such as breach by us or if we fail to
commercialize the products incorporating the licensed technology. In particular,
we have a license agreement with Symyx Technologies, Inc. relating to technology
incorporated in our Endeavor product. Either party can terminate this agreement
at its discretion at any time after December 31, 2000, upon six months' notice.
If our licenses to any such technology, or any similar licenses we may enter
into in the future, are terminated, we may be unable to continue selling such
products and our revenues would decline.

COMPETITION

We anticipate that competition will come primarily from companies providing
products based on traditional chemistry methods as well as companies that offer
competing products based on alternative technologies. In order to compete
effectively, we will need to demonstrate the advantages of our products over
well established traditional chemistry methods and alternative technologies and
products. We will also need to demonstrate the potential economic value of our
products relative to traditional chemistry methods. Some of the companies that
provide products that compete with ours include Mettler-Toledo AG, PE
Biosystems, Inc. and several smaller instrument and reagent companies. Our
future success will depend in large part on our ability to establish and
maintain a competitive position with respect to these products and future
technologies that may develop.

In many instances, our competitors and potential competitors have or will have
substantially greater financial, technical, research, and other resources and
larger, more established marketing, sales, distribution, and service
organizations than we do. Moreover, competitors may have greater name
recognition than we do, and may offer discounts as a competitive tactic. Our
competitors may succeed in developing or marketing technologies or products that
are more effective or commercially attractive than our products, or that would
render our technologies and products obsolete. Also, we may not have the
financial resources, technical expertise or marketing, distribution or support
capabilities to compete successfully in the future.

GOVERNMENT REGULATION

We are subject to various federal, state and local laws and regulations relating
to the protection of the environment. In the course of our business, we are
involved in the handling, storage and disposal of chemicals. The laws and
regulations applicable to our operations include provisions that regulate the

- --------------------------------------------------------------------------------
 40
<PAGE>   43
BUSINESS
- --------------------------------------------------------------------------------

discharge of materials into the environment. Usually these environmental laws
and regulations impose "strict liability," rendering a person liable without
regard to negligence or fault on the part of such person. Such environmental
laws and regulations may expose us to liability for the conduct of, or
conditions caused by, others, or for acts that were in compliance with all
applicable laws at the time the checks were performed. We have not been required
to make material expenditures in connection with our efforts to comply with
environmental requirements. We do not believe that compliance with such
requirements will have a material adverse effect upon our capital expenditures,
results of operations or competitive position. Because the requirements imposed
by such laws and regulations are frequently changed, we are unable to predict
the cost of compliance with such requirements in the future, or the effect of
such laws on our capital expenditures, results of operations or competitive
position.

EMPLOYEES

As of March 31, 2000, we had 99 employees. None of our employees are covered by
a collective bargaining agreement. We believe that our relations with our
employees are good.

FACILITIES

We occupy approximately 24,000 combined square feet of leased and sub-leased
office space and other facilities in San Carlos, California. These facilities
serve as the base for our marketing and product support operations, research and
development and manufacturing activities. Substantially all of our space is
leased through early 2001. We intend to use a portion of the proceeds of this
offering to relocate to new facilities. In addition, we lease approximately
2,000 square meters of office space in Muttenz, Switzerland and 2,000 square
meters of office space in Tokyo, Japan. These offices are the base operations
for our sales and support groups in the respective regions.

LEGAL PROCEEDINGS

From time to time, we may be involved in litigation that arises through the
normal course of business. As of the date of this prospectus, we are not a party
to any litigation we believe could reasonably be expected to materially harm our
business or results of operations.

MANAGEMENT
- --------------------------------------------------------------------------------

BOARD COMPOSITION

We currently have eight authorized directorships, of which two are vacant. In
accordance with the terms of our certificate of incorporation, the terms of
office of the directors are divided into three classes:

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

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

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

The Class I directors are Mr. James Schlater and Dr. Hingge Hsu, the Class II
directors are Mr. Brook Byers and Mr. Sam Colella, and the Class III director
are Drs. David Binkley and William Rastetter. At each annual meeting of
stockholders after the initial classification or special meeting in lieu
thereof, the successors to directors whose terms will then expire will be
elected to serve from the time of election and qualification until the third
annual meeting following election or special meeting held in lieu thereof. The
authorized number of directors may be changed only by resolution of the board of
directors or a super-majority vote of the stockholders. Any additional
directorships resulting from an increase in the number of directors will be
distributed among the three classes so that, as nearly as possible, each class
will consist of one third of the directors. This classification of the board of
directors may have the effect of delaying or preventing changes in control or
management.

BOARD COMMITTEES

The audit committee of the board of directors was established in May 1995. The
audit committee reviews, acts on and reports to the board of directors on
various auditing and accounting matters, including the recommendation of our
independent auditors, the scope of the annual audits, fees to be paid to the
independent auditors, the performance of our independent auditors and our
accounting practices. The members of our audit committee are Mr. Brook Byers,
Dr. Hingge Hsu and Mr. James Schlater, each of whom is an independent director.

The compensation committee of the board of directors was established in May
1995, and determines the salaries and benefits for our employees, directors and
other individuals compensated by us. The compensation committee also administers
our stock option plans, including determining the stock option grants for our
employees, consultants, directors and other individuals. The members of the
compensation committee are Mr. Brook Byers, Dr. William Rastetter and Mr. Samuel
Colella, each of whom is an independent director.

DIRECTOR COMPENSATION

Currently, we do not provide cash compensation to members of our board of
directors for serving on our board or for attendance at committee meetings.
Members of our board of directors are reimbursed for expenses in connection with
attendance at board and committee meetings. In consideration for services as
non-employee directors, we have in the past granted options to purchase our
common stock pursuant to the terms of our stock plans, and our board continues
to have the discretion to grant options to new non-employee directors. Beginning
in 2001 our outside directors will each receive annual nondiscretionary grants
of options to purchase 5,000 shares of our common stock.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

No member of the compensation committee has been an officer or employee of ours
at any time. None of our executive officers serves as a member of the board of
directors or compensation committee of any other company that has one or more
executive officers serving as a member of our board of directors or compensation
committee.

LIMITATION OF LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS

Our amended and restated certificate of incorporation and our amended and
restated bylaws provide that our directors and officers shall be indemnified by
us to the fullest extent authorized by Delaware law, as it now exists or may in
the future be amended, against all expenses and liabilities reasonably incurred
in connection with their service for or on our behalf. In addition, our amended
and restated certificate of incorporation provides that our directors will not
be personally liable for monetary damages to us for breaches of their fiduciary
duty as directors, unless they violated their duty of loyalty to us or our
stockholders, acted in bad faith, knowingly or intentionally violated the law,
authorized illegal dividends or redemptions or derived an improper personal
benefit from their action as directors. We have obtained insurance that insures
our directors and officers against specified losses and which insures us against
specific obligations to indemnify our directors and officers.

ended December 31, 1999.

Each option represents the right to purchase one share of our common stock. The
options generally become vested over four years. See "Management -- Employee
benefit plans" for more details regarding these options. In the year ended
December 31, 1999, we granted options to purchase an aggregate of 1,002,325
shares of our common stock to various officers, employees, directors and
consultants.

The potential realizable value at assumed annual rates of stock price
appreciation for the option term represents hypothetical gains that could be
achieved for the respective options if exercised at the end of the option term.
The 5% and 10% assumed annual rates of compounded stock price appreciation are
required by rules of the SEC and do not represent our estimate or projection of
our future common stock prices. These amounts represent assumed rates of
appreciation in the value of our common stock from the initial public offering
price (assuming an initial public offering price of $     per share). Actual
gains, if any, on stock option exercises are dependent on the future performance
of our common stock and overall stock market conditions. The amounts reflected
in the table may not necessarily be achieved.

EMPLOYMENT AGREEMENTS

By offer letter, dated October 29, 1996, we agreed that we would grant to David
P. Binkley, Ph.D., options to purchase 500,000 shares of our common stock that
would vest over time during the course of his employment. The letter further
provides that if we are acquired or merged with another company and Dr. Binkley
is not offered a position of similar responsibility with the new company and
subsequently leaves employment, any unvested options held by Dr. Binkley at such
time will automatically vest.

EMPLOYEE BENEFIT PLANS

1995 INCENTIVE STOCK PLAN

Our 1995 Incentive Stock Plan was approved by our board of directors in May 1995
and approved by our stockholders in May 1996. The 1995 Plan was subsequently
amended by the board of directors in November 1996, January and September 1997
and July 1999. Our 1995 plan authorizes the issuance of up to 3,935,308 shares
of our common stock as either incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986 or nonstatutory stock options.
As of March 31, 2000, we had 2,005,589 options to purchase common stock under
this plan outstanding to employees, directors and consultants with a weighted
average exercise price of $0.67 per share. After the completion of this
offering, no further options will be granted under this plan, the 1995 Plan will
terminate, and all unissued shares under the 1995 Plan as of the effective date
of this offering and all shares returned to the 1995 Plan shall be reserved for
issuance under the 2000 Incentive Stock Plan.

Our board of directors, or a board committee, has the power to determine the
terms of the options, including the exercise price of the options, the number of
shares subject to each option, the exercisability thereof, and the form of
consideration payable on such exercise, provided that the exercise price for
incentive stock options must be at least 100% of fair market value. Incentive
stock options granted to any holder of 10% or more of the combined voting power
of all classes of our stock must have an exercise price of not less than 110% of
fair market value and be exercisable for a term of no more than five years.

The 1995 Plan provides that in the event of our merger with or into another
corporation, options and stock purchase rights shall be assumed or substituted
for by the successor corporation. In the event the successor corporation refuses
to assume or substitute for our options or stock purchase rights, then the
options and stock purchase rights shall terminate as of the closing of the
merger.

2000 EMPLOYEE STOCK PURCHASE PLAN

Our 2000 Employee Stock Purchase Plan was adopted by our board of directors in
April 2000 and approved by our shareholders in                . A total of
200,000 shares of common stock have been reserved for issuance under our 2000
Employee Stock Purchase Plan, plus annual increases equal to the lesser of
500,000 shares, 2% of the outstanding shares on such date, or a lesser amount
determined by our board of directors.

Our 2000 Employee Stock Purchase Plan, which is intended to qualify under
Section 423 of the United States tax code, contains consecutive twenty-four
month offering period. Each offering period contains four six month purchase
periods. The offering periods generally start on the first trading day on or
after February 1 and August 1 of each year, except for the first such offering
period which commences on the first trading day on or after the effective date
of this offering and ends on the last trading day on or before July 31, 2002.

Employees are eligible to participate if they are customarily employed by us or
any participating subsidiary for at least 20 hours per week and more than five
months in any calendar year. However, any employee who immediately after grant
owns stock possessing 5% or more of the total combined voting power or value of
all classes of our capital stock, or whose rights to purchase stock under all of
our employee stock purchase plans accrues at a rate that exceeds $25,000 worth
of stock for each calendar year may not be granted an option to purchase stock
under this plan. The 2000 Employee Stock Purchase Plan permits participants to
purchase our common stock through payroll deductions of up to 15% of the
participant's "compensation." Compensation is defined as the participant's base
straight time gross earnings, bonuses, commissions, overtime payments, and
cash-based incentive compensation, but exclusive of any non-cash compensation.
The maximum number of shares a participant may purchase during a single purchase
period is 5,000 shares.

Amounts deducted and accumulated by the participant are used to purchase shares
of common stock at the end of each purchase period. The price of stock purchased
under the 2000 Employee Stock Purchase Plan is generally 85% of the lower of the
fair market value of the common stock at the beginning of the offering period or
at the end of the purchase period. Participants may end their participation at
any time during an offering period, and they will be paid their payroll
deductions to date. Participation ends automatically upon termination of
employment with us.

Rights granted under the 2000 Employee Stock Purchase Plan are not transferable
by a participant other than by will, the laws of descent and distribution, or as
otherwise provided under the plan. The 2000 Employee Stock Purchase Plan
provides that, in the event of our merger with or into another corporation or a
sale of substantially all our assets, each outstanding option may be assumed or
substituted for by the successor corporation. If the successor corporation
refuses to assume or substitute for the outstanding options, the offering period
then in progress will be shortened and a new exercise date will be set. The 2000
Employee Stock Purchase Plan will terminate automatically in 2010, unless
terminated earlier. Our board of directors has the authority to amend or
terminate the 2000 Employee Stock Purchase Plan, except that no such action may
adversely affect any outstanding rights to purchase stock under the 2000
Employee Stock Purchase Plan. Our board of directors has the exclusive authority
to interpret and apply the provisions of the 2000 Employee Stock Purchase Plan.

2000 INCENTIVE STOCK PLAN

Our 2000 Stock Plan was adopted by our board of directors in April, 2000, and
our stockholders approved the plan in                , 2000. This plan provides
for the grant of incentive stock options to our employees and nonstatutory stock
options and stock purchase rights to our employees, directors and consultants.
As of April   , 2000, a total of 2,000,000 shares of our common stock were
reserved

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

<PAGE>   51
MANAGEMENT
- --------------------------------------------------------------------------------

for issuance pursuant to our 2000 Stock Plan, plus any shares reserved for
issuance under the 1995 Plan as of the effective date of the Company's
registration statement and any shares returned to the 1995 Plan.

No options have yet been issued pursuant to the 2000 Stock Plan. The number of
shares reserved for issuance under our 2000 Stock Plan will increase annually on
the first day of the Company's fiscal year beginning in 2001 by an amount equal
to the lesser of 5% of the outstanding shares of our common stock on the first
day of the year, 1,500,000 shares or such lesser amount as our board of
directors may determine.

Our board of directors or a committee of our board administers the 2000 Stock
Plan. The committee may consist of two or more outside directors to satisfy
certain tax and securities requirements. The administrator has the power to
determine the terms of the options or stock purchase rights granted, including
the exercise price, the number of shares subject to each option or stock
purchase right, the exercisability of the options and the form of consideration
payable upon exercise. The administrator determines the exercise price of
options granted under our stock option plan, but with respect to incentive stock
options, the exercise price must at least be equal to the fair market value of
our common stock on the date of grant. Additionally, the term of an incentive
stock option may not exceed ten years. The administrator determines the term of
all other options. No optionee may be granted an option to purchase more than
500,000 shares in any fiscal year. In connection with his or her initial
service, an optionee may be granted an additional option to purchase up to
500,000 shares of our common stock. After termination of one of our employees,
directors or consultants, he or she may exercise his or her option for the
period of time stated in the option agreement. If termination is due to death or
disability, the option will generally remain exercisable for 12 months following
such termination. In all other cases, the option will generally remain
exercisable for three months. However, an option may never be exercised later
than the expiration of its term.

The administrator determines the exercise price of stock purchase rights granted
under our 2000 Stock Plan. Unless the administrator determines otherwise, the
restricted stock purchase agreement will grant us a repurchase option that we
may exercise upon the voluntary or involuntary termination of the purchaser's
service with us for any reason, including death or disability. The purchase
price for shares we repurchase will generally be the original price paid by the
purchaser. The administrator determines the rate at which our repurchase option
will lapse. Our stock option plan generally does not allow for the transfer of
options or stock purchase rights and only the optionee may exercise an option
and stock purchase right during his or her lifetime.

Our stock option plan provides that in the event of our merger with or into
another corporation or a sale of substantially all of our assets, the successor
corporation will assume or substitute for each option or stock purchase right
outstanding under our 2000 Stock Plan. If the outstanding options or stock
purchase rights are not assumed or substituted for, all outstanding options and
stock purchase rights become fully vested and exercisable. Our 2000 Stock Plan
will automatically terminate in 2010, unless we terminate it sooner. In
addition, our board of directors has the authority to amend, suspend or
terminate the 2000 Stock Plan provided it does not adversely affect any option
previously granted under our 2000 stock Plan.

DIRECTOR OPTION PROGRAM

The Director Option Program is part of our 2000 Stock Plan and provides for the
periodic grant of nonstatutory stock options to those non-employee directors who
are not "beneficial owners" (as defined in Rule 13d-3 of the Securities Act of
1934) of 2.5% or more of the Company's total voting power on the date of any
grant under the 2000 Stock Plan.

<PAGE>   52
MANAGEMENT
- --------------------------------------------------------------------------------

All grants of options to our non-employee directors under the Director Program
are automatic. We will grant to each individual who first become a non-employee
director on or after our initial public offering, an option to purchase 15,000
shares when such person first becomes a non-employee director (except for those
directors who became non-employee directors by ceasing to be employee
directors). The shares subject to the option vest monthly over a three-year
term, provided the individual remains an outside director on such dates.

Each outside director shall automatically be granted an option to purchase 5,000
shares on each annual meeting of the shareholders of the Company occurring after
the end of our fiscal year 2000, if immediately after such meeting, he or she
shall continue to serve on the board and has been a director for at least six
months prior to the annual shareholders meeting. Such shares subject to the
option vest monthly over a one-year term, provided the individual remains an
outside director on such dates.

All options granted under our Director Program have a term of ten years and an
exercise price equal to fair market value on the date of grant. After
termination as a non-employee director with us, an optionee must exercise an
option at the time set forth in his or her option agreement. If termination is
due to death or disability, the option will remain exercisable for 12 months. In
all other cases, the option will remain exercisable for a period of three
months. However, an option may never be exercised later than the expiration of
its term. A non-employee director may not transfer options granted under our
Director Program other than by will or the laws of descent and distribution.
Only the non-employee director may exercise the option during his or her
lifetime.

In the event of a change of control of us, all of our outstanding options
granted pursuant to the Director Option Program become fully vested and
exercisable.

Description of capital stock

The following information describes our common stock and preferred stock, as
well as options and warrants to purchase our common stock, and provisions of our
certificate of incorporation and our bylaws, all as will be in effect upon the
closing of this offering. We intend to amend our certificate of incorporation
and by-laws prior to completion of the offering. This description is only a
summary. You should also refer to our certificate of incorporation and bylaws,
which have been filed with the SEC as exhibits to our registration statement, of
which this prospectus forms a part. The descriptions of our common stock and
preferred stock, as well as options and warrants to purchase our common stock,
reflect changes to our capital structure that will occur upon the closing of
this offering in accordance with the terms of our amended certificate of
incorporation.

Upon completion of this offering, our authorized capital stock will consist of
          shares of common stock, par value $0.0001 per share, and
shares of preferred stock, par value $0.0001 per share.

COMMON STOCK

As of March 31, 2000, there were 2,746,521 shares of our common stock
outstanding and held of record by 105 stockholders. There will be
shares of our common stock outstanding upon the closing of this offering, which
gives effect to the issuance of           shares of our common stock offered by
us under this prospectus and the conversion of our preferred stock discussed
below.

Each share of our common stock has identical rights and privileges in every
respect. The holders of our common stock are entitled to vote upon all matters
submitted to a vote of our stockholders and are entitled to one vote for each
share of our common stock held.

Subject to the prior rights and preferences, if any, applicable to shares of our
preferred stock or any series of our preferred stock, the holders of our common
stock are entitled to receive dividends, payable in cash, stock or otherwise, as
may be declared by our board out of any funds legally available for the payment
of dividends.

If we voluntarily or involuntarily liquidate, dissolve or wind-up, the holders
of our common stock will be entitled to receive after distribution in full of
the preferential amounts, if any, to be distributed to the holders of our
preferred stock or any series of our preferred stock, all of the remaining
assets available for distribution ratably in proportion to the number of shares
of our common stock held by them. Holders of our common stock have no
preferences or any preemptive conversion or exchange rights.

PREFERRED STOCK

As of March 31, 2000, there were 11,339,268 shares of our convertible preferred
stock outstanding. Upon the closing of this offering, all outstanding shares of
our convertible preferred stock will be automatically converted into 11,339,268
shares of our common stock and will be held of record by 43 stockholders. These
shares of our convertible preferred stock will no longer be authorized, issued
or outstanding. Our amended and restated certificate of incorporation, which
becomes effective upon the closing of this offering, authorizes the issuance of
          shares of our preferred stock, par value $0.0001 per share.

Upon completion of this offering our board will be authorized to provide for the
issuance of shares of our preferred stock in one or more series, and to fix for
each series voting rights, if any, designations,

preferences and relative, participating, optional or other special rights and
such qualifications, limitations or restrictions as provided in a resolution or
resolutions adopted by the board. Our board will have the ability to authorize
the issuance of shares of our preferred stock with terms and conditions that
could discourage a takeover or other transaction that holders of some or a
majority of shares of our common stock might believe to be in their best
interests or in which holders of our common stock might receive a premium for
their shares over the then market price.

WARRANTS

As of March 31, 2000, warrants to purchase a total of 50,000 shares of our
common stock, at an exercise price of $1.20 per share, were outstanding. As of
March 31, 2000, warrants to purchase a total of 91,665 shares of our Series C
preferred stock, at an exercise price of $6.00 per share, were outstanding. The
warrants contain anti-dilution provisions providing for adjustments of the
exercise price and the number of shares underlying the warrants upon the
occurrence of certain events, including any recapitalization, reclassification,
stock dividend, stock split, stock combination or similar transaction. The
warrants expire as follow: warrants to purchase 6,802 shares of Series C
preferred stock, expires on the earlier of July 7, 2004 or the third anniversary
of the current offering; warrants to purchase 28,197 shares of Series C
preferred stock, expires on the earlier of August 12, 2004 or the third
anniversary of the current offering; warrants to purchase 36,666 shares of
Series C preferred stock, expires on the earlier of July 7, 2005 or the third
anniversary of the current offering; warrant to purchase 20,000 Shares of Series
C preferred stock, expires on the earlier of January 19, 2006 or the third
anniversary of the current offering; and warrant to purchase 50,000 shares of
common stock, expires on April 17, 2001. All of these warrants will be
exercisable immediately before this offering.

REGISTRATION RIGHTS

Under the terms of an agreement with some of our stockholders, the holders of
our common and preferred stock representing 12,330,135 shares of common stock,
on an as converted basis, are entitled to demand the registration of their
shares under the Securities Act of 1933. The holders of at least 40% of such
shares or the holders of shares worth the equivalent of $5 million, if lesser,
are entitled to demand that we register their shares under the Securities Act of
1933 subject to limitations described in the relevant agreement. We are not
required to effect more than two registrations for such holders pursuant to
these demand registration rights. These demand rights expire on either the fifth
anniversary of the effective date of this offering or, for an individual holder,
upon a holder's becoming eligible to sell, in accordance with Rule 144 of the
Securities Act of 1933 and within a three month period, all shares with
registration rights held by such holder, whichever is later. In addition, these
holders are entitled to piggyback registration rights with respect to the
registration of their shares of our common stock. If we propose to register any
shares of our common stock either for our account or for the account of other
security holders, the holders of shares having piggyback rights are entitled to
receive notice of the registration and are entitled to include their shares in
the registration, subject to some limitations. Further, at any time after we
become eligible to file a registration statement on Form S-3, a holder or
holders of shares with registration rights may require us to file registration
statements under the Securities Act of 1933 on Form S-3 with respect to their
shares of our common stock if the aggregate offering price of these shares is
expected to exceed $1,000,000. These registration rights are subject to
additional conditions and limitations, among which is the right of the
underwriters of an offering to limit the number of shares of our common stock
held by security holders with registration rights to be included in such
registration. We are generally required to bear all of the expenses of all these
registrations except selling expenses incurred on behalf of holders requesting
registration. We are not required to pay any registration expenses for Form S-3
registrations after the fourth such registration has been requested.
Registration of any of the shares of our common

stock held by security holders with registration rights would result in such
shares becoming freely tradable without restriction under the Securities Act of
1933.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS
AND DELAWARE LAW

Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make the following transactions more difficult:

+  the acquisition of us by means of a tender offer;

+  the acquisition of us by proxy contest or other means; and

+  the removal of our incumbent officers and directors.

These provisions, summarized below, are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of us to first negotiate with us. We believe
that the benefits of increased protection of our potential ability to negotiate
with the proponent of an unfriendly or unsolicited proposal to acquire or
restructure our company outweighs the disadvantages of discouraging such
proposals because, among other things, negotiation of such proposals could
result in an improvement of their terms. The amendment of any of the following
provisions would require approval by holders of at least 66 2/3% of our
outstanding common stock.

ELECTION AND REMOVAL OF DIRECTORS
Effective upon filing of our amended and restated certificate of incorporation
upon completion of this offering, our amended and restated bylaws provide for
the division of our board of directors into three classes, as nearly equal in
number as possible, with the directors in each class serving for three-year
terms, and one class being elected each year by our stockholders. This system of
electing and removing directors may tend to discourage a third party from making
a tender offer or otherwise attempting to obtain control of us and may maintain
the incumbency of our board of directors, as it generally makes it more
difficult for stockholders to replace a majority of the directors. Further, our
amended and restated certificate of incorporation to be filed upon completion of
this offering and restated bylaws do not provide for cumulative voting in the
election of directors.

STOCKHOLDER MEETINGS
Under our amended and restated certificate of incorporation and amended and
restated bylaws, only our board of directors, chairman of the board or chief
executive officer may call special meetings of stockholders. Our restated bylaws
establish advance notice procedures with respect to stockholder proposals and
the nomination of candidates for election as directors, other than nominations
made by or at the direction of the board of directors or a committee thereof. In
addition, our amended and restated certificate of incorporation eliminates the
right of stockholders to act by written consent without a meeting and eliminates
cumulative voting.

UNDESIGNATED PREFERRED STOCK
The authorization of undesignated preferred stock makes it possible for the
board of directors to issue preferred stock with voting or other rights or
preferences that could impede the success of any attempt to change control of
us. These and other provisions may have the effect of deterring or delaying
hostile takeovers or delaying changes in control or management.

DESCRIPTION OF CAPITAL STOCK

SECTION 203
We are subject to Section 203 of the Delaware General Corporation Law. In
general, the statute prohibits a Delaware corporation from engaging in any
business combination with any interested stockholder for a period of three years
following the date that the stockholder became an interested stockholder unless:

+  prior to the date, the board of directors of the corporation approved either
   the business combination or the transaction that resulted in the stockholder
   becoming an interested stockholder;

+  upon consummation of the transaction that resulted in the stockholder's
   becoming an interested stockholder, the interested stockholder owned at least
   85% of the voting stock of the corporation outstanding at the time the
   transaction commenced, excluding those shares owned by persons who are
   directors or officers, and employee stock plans in which employee
   participants do not have the right to determine confidentially whether shares
   held subject to the plan will be tendered in a tender or exchange offer; or

+  on or subsequent to the date, the business combination is approved by the
   board of directors and authorized at an annual or special meeting of
   stockholders, and not by written consent, by the affirmative vote of at least
   two-thirds of the outstanding voting stock that is not owned by the
   interested stockholder.

Section 203 defines "business combination" to include:

+  any merger or consolidation involving the corporation and the interested
   stockholder;

+  any sale, transfer, pledge or other disposition involving the interested
   stockholder of 10% or more of the assets of the corporation;

+  subject to exceptions, any transaction that results in the issuance or
   transfer by the corporation of any stock of the corporation to the interested
   stockholder; or

+  the receipt by the interested stockholder of the benefit of any loans,
   advances, guarantees, pledges or other financial benefits provided by or
   through the corporation.

In general, Section 203 defines an interested stockholder as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by the entity or person.

Shares eligible for future sale

Prior to this offering, there has been no public market for our common stock.
The market price of our common stock after this offering could decline as a
result of the sale of a large number of shares of our common stock in the
market, or the perception that such sales could occur. Such sales also could
make it more difficult for us to sell equity securities in the future at a time
and price that we deem appropriate.

Upon completion of this offering,        shares of our common stock will be
outstanding, based upon the number of shares outstanding as of March 31, 2000.
The        shares of our common stock sold in this offering will be immediately
eligible for resale in the public market without restriction under the
Securities Act, except that any shares purchased in this offering by our
"affiliates," as that term is defined in Rule 144 under the Securities Act of
1933, may generally be resold only in compliance with applicable provisions of
Rule 144. The remaining shares of our common stock are "restricted securities,"
as defined under the Securities Act of 1933. After this offering approximately
       of these restricted shares will be immediately eligible for sale in the
public market without restriction pursuant to Rule 144(k). Beginning 90 days
after the date of this prospectus, approximately        additional restricted
shares, exclusive of the Rule 701 shares described below, will become eligible
for resale in the public market, subject to compliance with applicable
provisions of Rule 144. Substantially all of these shares are subject to the
lock-up agreements described below.

In general, under Rule 144 of the Securities Act of 1933, a person or persons
whose shares are required to be aggregated, including an affiliate, whose shares
have been owned for at least one year is entitled to sell, within any
three-month period after the date of this prospectus, a number of shares that
does not exceed the greater of 1% of the then outstanding shares of common
stock -- approximately        shares immediately after this offering -- or the
average weekly trading volume in our common stock during the four calendar weeks
preceding the date on which notice of such sale is filed, subject to certain
restrictions. In addition, a person who is not deemed to have been an affiliate
of ours at any time during the 90 days preceding a sale and whose shares have
been beneficially owned by nonaffiliates for at least two years would be
entitled to sell such shares under Rule 144(k) without regard to the
requirements described above. To the extent that shares were acquired from one
of our affiliates, such person's holding period for the purpose of effecting a
sale under Rule 144 commences on the date of transfer from the affiliate.

The holders of        % of our common stock, including all of our directors and
officers, together with the holders of options to purchase        shares of
common stock and the holders of warrants to purchase        shares of common
stock, have entered into lock-up agreements under which they have agreed with
the underwriters not to offer, sell, contract to sell, hedge or otherwise
dispose of, directly or indirectly, or file with the SEC a registration
statement under the Securities Act relating to, any of its common stock or
securities convertible into or exchangeable for shares of common stock during
the period from the date of this prospectus continuing through the date 180 days
after the date of this prospectus, without the prior written consent of Warburg
Dillon Read LLC.

Rule 701 under the Securities Act of 1933 provides an exemption from
registration for offers and sales of securities issued pursuant to certain
compensatory benefit plans, such as our stock option and stock incentive plans,
by a company not subject to the reporting requirements of the Securities
Exchange Act of 1934. Securities issued pursuant to Rule 701 are defined as
"restricted securities" for purposes of Rule 144. However, 90 days after the
issuer becomes subject to the reporting provisions of the Exchange Act, the Rule
144 resale restrictions, except for the broker's transaction requirement, are
inapplicable for non-affiliates. Affiliates are subject to all Rule 144
restrictions after this 90-day period

                                                                              59

SHARES ELIGIBLE FOR FUTURE SALE
- --------------------------------------------------------------------------------

other than the holding period restriction. There are currently outstanding
          shares of our common stock that will qualify for sale under Rule 701.
In addition,           shares underlying currently outstanding options will
qualify for sale under Rule 701. Of these option shares, we expect approximately
          will be vested 90 days after this offering. Substantially all of these
Rule 701 shares are subject to the lock-up agreements described below.

Upon the closing of this offering, we intend to file a registration statement to
register for resale the           shares of common stock reserved for issuance
under our stock option plans. We expect the registration statement to become
effective immediately upon filing. Shares issued upon the exercise of stock
options granted under our stock option plans will be eligible for resale in the
public market from time to time subject to vesting and, in the case of certain
options, the expiration of the lock-up agreements referred to above.

Stockholders holding warrants to purchase 91,665 shares of preferred stock and
50,000 shares of common stock have the right, subject to various conditions and
limitations, to include their shares in registration statements relating to our
securities. By exercising their registration rights and causing a large number
of shares to be registered and sold in the public market, these holders may
cause the price of the common stock to fall. In addition, any demand to include
such shares in our registration statement could have a material adverse effect
on our ability to raise needed capital. See "Management -- Benefit plans,"
"Principal stockholders," "Shares eligible for future sale" and "Underwriting."

If the underwriters sell more shares than the total number of shares set forth
in the table above, the underwriters have a 30-day option to buy from us up to
an           additional shares at the initial public offering price less the
underwriting discounts and commissions to cover these sales. If shares are
purchased under this option, the underwriters will severally purchase the shares
in approximately the same proportion as set forth in the table above.

The following table shows the per share and total underwriting discounts and

We estimate that the total expenses of the offering payable by us, excluding
underwriting discounts and commissions, will be approximately $          .

Shares sold by the underwriters to the public will initially be offered at the
initial public offering price set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a discount
of up to $     per share from the initial public offering price. Any of these
securities dealers may resell any shares purchased from the underwriters to
other brokers or dealers at a discount of up to $     per share from the initial
public offering price. If all the shares are not sold at the initial public
offering price, the representatives may change the offering price and the other
selling terms.

The underwriters have informed us that they do not expect discretionary sales to
exceed 5% of the shares of common stock to be offered.

We, our directors, officers and certain of our stockholders have agreed with the
underwriters not to offer, sell, contract to sell, hedge or otherwise dispose
of, directly or indirectly, or file with the SEC a registration statement under
the Securities Act relating to, any of our common stock or securities
convertible into or exchangeable for shares of our common stock during the
period beginning on the date of this prospectus continuing through the date 180
days after the date of this prospectus, without the prior written consent of
Warburg Dillon Read LLC.

The underwriters have reserved for sale, at the initial public offering price,
up to        shares of our common stock being offered for sale to our customers
and business partners. At the discretion of our management, other parties,
including our employees, may participate in our reserved share program.

UNDERWRITING
- --------------------------------------------------------------------------------

The number of shares available for sale to the general public in the offering
will be reduced to the extent these persons purchase reserved shares. Any
reserved shares not so purchased will be offered by the underwriters to the
general public on the same terms as the other shares in this offering.

Prior to this offering, there has been no public market for our common stock.
The initial public offering price will be determined by negotiation between us
and the representatives of the underwriters. The principal factors to be
considered by the representatives and us in determining the initial public
offering price include:

+  the information set forth in this prospectus and otherwise available to the
   representatives;

+  the history and the prospects for the industry in which we compete;

+  the ability of our management;

+  our prospects for future earnings, the present state of our development, and
   our current financial position;

+  the general condition of the securities markets at the time of this offering;
   and

+  the recent market prices of, and the demand for, publicly traded common stock
   of generally comparable companies.

In connection with the offering, the underwriters may purchase and sell shares
of our common stock in the open market. These transactions by the underwriters
may include short sales, stabilizing transactions and purchases to cover
positions created by short sales. Short sales involve the sale by the
underwriters of a greater number of our shares than they are required to
purchase in the offering. Stabilizing transactions consist of bids or purchases
made for the purpose of preventing or retarding a decline in the market price of
our common stock while our offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular
underwriter repays to the underwriters a portion of the underwriting discount
received by it because the representatives have repurchased shares sold by or
for the account of that underwriter in stabilizing or short covering
transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect
the market price of our common stock. As a result, the price of our common stock
may be higher than the price that otherwise might exist in the open market. If
these activities are commenced, they may be discontinued by the underwriters at
any time. These transactions may be effected by the underwriters on the Nasdaq
National Market, in the over-the-counter market or otherwise.

We have agreed to indemnify the several underwriters against some liabilities,
including liabilities under the Securities Act of 1933 and to contribute to
payments that the underwriters may be required to make in respect thereof.

REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Argonaut Technologies, Inc.

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

We conducted our audits in accordance with 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 Argonaut
Technologies, Inc. at December 31, 1998 and 1999, 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.

synthesis is a process by which multiple compounds are created simultaneously.
The Company's products include a variety of parallel chemical synthesizers and
reagents and enable chemists to increase their productivity, accelerate the drug
development process and reduce costs. The Company's products are used for
chemistry development in the pharmaceutical, biotechnology, life sciences, and
chemical research fields worldwide. Its principal markets are in the United
States, Western Europe, and the Far East.

The Company has two wholly owned subsidiaries, Argonaut Technologies KK in Japan
and Argonaut Technologies AG in Switzerland.

The Company's current operating plan anticipates that the Company will require
additional capital to fund its operations, continue its research and development
programs, and build its sales and marketing organization prior to reaching
profitability. To date, the Company has financed its operations with proceeds
from private equity offerings, long-term debt, and from equipment leases and
other financing arrangements. The Company plans to seek additional funding
through public or private financing arrangements with third parties. Should the
Company fail to raise additional funding, it will be required to delay, reduce
the scope of, or eliminate its operations or obtain funds through arrangements
with collaborative partners or others that may require the Company to relinquish
rights to certain technologies or products that the Company may otherwise seek
to retain.

PRINCIPLES OF CONSOLIDATION
The consolidated financial statements include the assets and liabilities of the
Company and its wholly owned subsidiaries, Argonaut Technologies KK and Argonaut
Technologies AG. All significant intercompany accounts and transactions have
been eliminated on consolidation.

INTERIM FINANCIAL INFORMATION
The financial information at March 31, 2000 and for the three months ended March
31, 1999 and 2000 is unaudited but, in the opinion of management, has been
prepared on the same basis as the annual financial statements and includes all
adjustments (consisting only of normal recurring adjustments) that the Company
considers necessary for a fair presentation of the financial position at such
date and the operating results and cash flows for such periods. Results for the
three months ended March 31, 2000 are not necessarily indicative of the results
to be expected for any subsequent period.

UNAUDITED PRO FORMA INFORMATION
If the Company's initial public offering ("IPO") as described in Note 12 is
consummated, all of the preferred stock outstanding will automatically be
converted into common stock. The unaudited pro forma stockholders' equity at
March 31, 2000 has been adjusted for the assumed conversion of preferred stock
based on the shares of preferred stock outstanding at March 31, 2000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

FOREIGN CURRENCY TRANSLATION
The Company translates the assets and liabilities of its foreign subsidiaries
stated in local functional currencies to U.S. dollars at the rates of exchange
in effect at the end of the period. Revenues and expenses are translated using
rates of exchange in effect during the period. Gains and losses from translation
of financial statements denominated in foreign currencies, if material, are
included in stockholders' equity.

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

CASH, CASH EQUIVALENTS, AND SHORT-TERM INVESTMENTS
The Company invests its excess cash in deposits, money market accounts, and high
quality marketable debt securities. The Company considers all highly liquid
investments with a maximum original maturity of 90 days or less at the time of
purchase to be cash equivalents.

The Company accounts for its investments in marketable securities in accordance
with Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities" ("SFAS 115").

Under SFAS 115, all affected debt and equity securities must be stated at fair
value and classified as held-to-maturity, trading, or available-for-sale.
Management determines the appropriate classification of securities at the time
of purchase and reevaluates such designation as of each balance sheet date.

All investments in debt securities have been designated as available-for-sale.
Available-for-sale securities are carried at fair value, with unrealized gains
and losses reported as a separate component of stockholders' equity, if
material. Realized gains and losses and declines in value judged to be other-
than-temporary, if any, on available-for-sale securities are included in other
income. The cost of securities sold is based on the specific identification
method. Interest on securities classified as available-for-sale is included in
interest income.

REVENUE RECOGNITION
The Company recognizes revenue when earned. For products with no future
obligation, revenue is recognized upon shipment. For those products where the
Company has obligations to provide installation services, revenue is recognized
upon installation. Sales which require customer acceptance or have rights of
return are not recognized as revenue until the requirements have been met or
rights of return have expired.

The Company has entered into agreements with certain customers whereby the
customers provide funds for the development of new products or product
enhancements. Generally the amount paid by the customers can be applied toward
the purchase of products from the Company. These amounts have been recorded as
deferred revenue in the accompanying balance sheet and will be recognized when
earned.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

ADVERTISING COSTS
Advertising costs are accounted for as expenses in the period in which they are
incurred. Advertising expense for 1997, 1998, and 1999 was $195,000, $243,000,
and $274,000, respectively, and $122,000 for the three months ended March 31,
2000.

INVENTORIES
Inventories are stated at the lower of standard cost (which approximates actual
costs on a first-in, first-out cost method) or market value.

PROPERTY AND EQUIPMENT
Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation and amortization are calculated using the
straight-line method over the estimated useful lives of the assets, which range
from two to five years. Leasehold improvements are amortized over the shorter of
the lease term or the estimated useful life.

IMPAIRMENT OF LONG-LIVED ASSETS
In accordance with the provisions of Statement of Financial Accounting Standards
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of" ("SFAS 121"), the Company reviews long-lived assets,
including property and equipment, for impairment whenever events or changes in
business circumstances indicate that the carrying amount of the assets may not
be fully recoverable. Under SFAS 121, an impairment loss would be recognized
when estimated undiscounted future cash flows expected to result from the use of
the asset and its eventual disposition is less than it carrying amount.
Impairment, if any, is assessed using discounted cash flows. Through March 31,
2000, there have been no such losses.

CONCENTRATIONS OF RISK
The Company outsources part of its manufacturing process to third party
contractors. There are no other third party contractors who could readily assume
this manufacturing function on short notice. Any delay in production could
result in failure to meet customer demand.

ACCOUNTING FOR STOCK-BASED COMPENSATION
As permitted by Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" ("SFAS 123"), the Company has elected to continue
to account for its 1995 Incentive Stock Plan and issuances of restricted stock
to employees in accordance with the provisions of Accounting Principles Board
No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations. Pro forma disclosures required by SFAS 123 are included in Note
8.

COMPREHENSIVE LOSS
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS 130"), requires unrealized gains or losses on the Company's
available-for-sale securities and foreign currency translation adjustments to be
included as part of total comprehensive loss. Total comprehensive loss has been
disclosed in the consolidated statement of stockholders' equity.

NET LOSS PER SHARE
Net loss per share has been computed according to the Financial Accounting
Standards No. 128, "Earnings Per Share," which requires disclosure of basic and
diluted earnings per share. Basic earnings

per share excludes any dilutive effects of options, shares subject to
repurchase, warrants, and convertible securities. Diluted earnings per share
includes the impact of potentially dilutive securities (calculated using the
treasury stock method). Following the guidance given by the Securities and
Exchange Commission Staff Accounting Bulletin No. 98, common stock and preferred
stock that has been issued or granted for nominal consideration prior to the
anticipated effective date of the initial public offering must be included in
the calculation of basic and diluted net loss per common share as if these
shares had been outstanding for all periods presented. To date, the Company has
not issued or granted shares for nominal consideration.

Pro forma net loss per share includes shares issuable upon the conversion of
outstanding shares of preferred stock (using the as-if-converted method) from
the original date of issuance.

A reconciliation of shares used in the calculations is as follows (in
thousands):

for the recognition and measurement of derivatives and hedging activities. In
June 1999, the FASB issued Statement of Financial Accounting Standards No. 137,
which defers the effective date of SFAS 133 to years beginning after June 15,
2000. The Company does not anticipate SFAS 133 will have an impact on its
results of operations or financial condition when adopted.

In December 1999, the Securities and Exchange Commission ("SEC") released Staff

7. LONG-TERM DEBT

In July 1997, the Company entered into a loan agreement for $1.5 million with a
financial institution. The loan has an interest rate of 10.5% and is repayable
in 30 monthly installments after six months of interest-only payments. It is
secured by the assets of the Company and subordinated to institutional
creditors. The annual principal maturity of the debt at December 31, 1999 was
approximately $439,000 in 2000.

In July 1998, the Company entered into a loan agreement (the "Loan") and a
receivables loan agreement (the "Receivables Loan") with a financial institution
for a total of up to $8.0 million ($4.0 million under each loan). The Loan bears
interest at rates of 11.75% to 12.5% and is repayable in 16 quarterly
installments after an initial three quarters of interest-only payments. The
Receivables Loan bears interest at prime plus 1.5% at the time of the draw down
and the average interest rate for 1999 was 10.0%. The Receivables Loan is
repayable two years after the draw down and interest is payable monthly.

Also, under the terms of the Loan agreement, the Company is required to issue
warrants to purchase 20,000 shares of Series C convertible preferred stock for
each draw down of $1.0 million. Under the terms of the Receivables Loan
agreement, the Company is required to issue two warrants each to purchase 16,666
shares of Series C convertible preferred stock, one on signing of the agreement
and the second if the draw down exceeds $2.0 million. Both loans are secured by
the assets of the Company and subordinated to institutional creditors.

At December 31, 1999, the Company had drawn down $2.0 million against the Loan
line and $2.0 million against the Receivables Loan line and issued three
warrants to purchase a total of 56,666 shares of Series C convertible preferred
stock (see Note 8). The aggregate annual principal maturities of the debt at
December 31, 1999 were approximately: $2.5 million in 2000, $612,000 in 2001,
$688,000 in 2002, and $91,000 in 2003.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Under the terms of each of the loan agreements, the Company is prohibited from
declaring dividends without the consent of the financial institution.

8. STOCKHOLDERS' EQUITY

CONVERTIBLE PREFERRED STOCK
All series of preferred stock are convertible at the stockholders' option at any
time into common stock on a one-for-one basis, subject to adjustment for
antidilution. Conversion is automatic upon the closing of an underwritten public
offering with aggregate offering proceeds exceeding $25,000,000 and an offering
price of at least $6.50 per share (appropriately adjusted for any stock splits,
stock dividends, recapitalization, or similar events) or written election of
holders of record or more than 2/3 of the outstanding shares.

Holders of Series A, A-1, B, B-1, C, C-1, D, and D-1 convertible preferred stock
are entitled to noncumulative dividends of $0.08, $0.08, $0.26, $0.26, $0.40,
$0.40, $0.46 and $0.46 per share, respectively, if and when declared by the
board of directors. These dividends are to be paid in advance of any
distributions to common stockholders. No dividends have been declared through
March 31, 2000.

In the event of a liquidation or winding up of the Company, holders of Series A,
A-1, B, B-1, C, C-1, D, and D-1 convertible preferred stock shall have a
liquidation preference of $1.00, $1.00, $3.25, $3.25, $5.00, $5.00, $5.75, and
$5.75 per share, respectively, together with any declared but unpaid dividends,
over holders of common shares.

Preferred stockholders are entitled to the number of votes they would have upon
conversion of their preferred shares into common stock.

The authorized, issued and outstanding Series A, A-1, B, B-1, C, C-1, D, and D-1
shares of convertible preferred stock were as follows:

WARRANTS
In conjunction with a capital lease line executed in April 1995, the Company
issued a warrant to purchase 50,000 shares of common stock at an exercise price
of $1.20 per share. The warrant expires in April 2001.

In 1997, the Company issued a series of warrants to purchase 34,999 shares of
Series C convertible preferred stock at an exercise price of $6.00 per share in
connection with the execution of a capital lease line and a loan and security
agreement. These warrants are exercisable for a period of seven years or three
years from the effective date of the Company's initial public offering,
whichever is longer. However, should the Company accelerate repayment of its
borrowings under this arrangement, the number of shares which may be purchased
in connection with these warrants would be reduced.

In 1998, the Company issued two warrants to purchase a total of 36,666 shares of
Series C convertible preferred stock at an exercise price of $6.00 per share in
connection with two loan agreements entered into in July 1998 (see Note 7).
These warrants are exercisable for a period of seven years or three years from
the effective date of the Company's initial public offering, whichever is
longer. The fair value of these warrants, determined using a Black-Scholes
valuation model, was $40,699 and is being amortized to interest expense over the
term of the loan.

In 1999, the Company issued one warrant to purchase 20,000 shares of Series C
convertible preferred stock at an exercise price of $6.00 per share in
connection with a drawdown on one of their loans (see Note 7). The warrant is
exercisable for a period of seven years or three years from the effective date
of the Company's initial public offering, whichever is longer. The fair value of
the warrant, determined using a Black-Scholes valuation model, was $22,200 and
is being amortized to interest expense over the term of the loan.

1995 INCENTIVE STOCK PLAN
The Company's 1995 Incentive Stock Plan (the "Plan") provides for (i) the grant
of incentive stock options to employees, (ii) the grant of nonstatutory stock
options to employees and consultants, and (iii) the grant of stock purchase
rights. A total of 3,935,308 shares of common stock have been authorized for
issuance under the Plan.

Under the terms of the Plan, the options and purchase rights granted generally
vest at a rate of 25% at the end of the first year with the remaining balance
vesting in equal amounts over the next 36 months.

Pro forma information regarding net income and net loss per share is required by
SFAS 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that Statement. The fair
value of these options was estimated at the date of grant using the minimum
value method with the following assumptions in 1997, 1998, and 1999: risk-free
interest rate of 6.11%, 5.08%, and 5.32%, respectively; an expected option life
of 6.5 years, 6.5 years, 7 years, respectively; and no dividends. The
weighted-average fair value of the stock options granted were $0.15 in 1997 and
1998, $0.30 in 1999, and $0.31 at March 31, 2000.

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

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law permits a corporation to
include in its charter documents, and in agreements between the corporation and
its directors and officers, provisions expanding the scope of indemnification
beyond that specifically provided by the current law.

Article VIII of the Registrant's Amended and Restated Certificate of

with respect to any criminal action or proceeding, the indemnified party had no
reason to believe his or her conduct was unlawful.

The Registrant has entered into indemnification agreements with its directors
and executive officers, in addition to indemnification provided for in the
Registrant's Amended and Restated Bylaws, and intends to enter into
indemnification agreements with any new directors and executive officers in the

ITEM 17. UNDERTAKINGS

The undersigned Registrant hereby undertakes to provide to the underwriters, at
the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and

- --------------------------------------------------------------------------------
II- 4
<PAGE>   91
PART II
- --------------------------------------------------------------------------------

contained in a form of prospectus filed by the Registrant pursuant to Rule
424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part
of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial bona fide offering thereof.

Preferred at such annual rate for such fiscal year of the corporation. After the
holders of Series A Preferred, Series A-1 Preferred, Series B Preferred, Series
B-1 Preferred, Series C Preferred, Series C-1 Preferred, Series D Preferred, and
Series D-1 Preferred have received their dividend preference as set forth above,
the holders of Preferred Stock and Common Stock shall be entitled, when, as and
if declared by the Board of Directors, to dividends out of the corporation's
assets legally available therefor; provided, however, that no such dividends may
be declared or paid on any shares of Common Stock or Preferred Stock unless at
the same time an equivalent dividend is declared and paid on all outstanding
shares of Common Stock and Preferred Stock; and provided further that the
dividend on each series of Preferred Stock shall be payable at the same rate per
share as would be payable on the shares of Common Stock or other securities into
which such series of Preferred Stock is convertible immediately prior to the
record date for such dividend. The right to dividends on shares of the Common
Stock or Preferred Stock shall not be cumulative, and no right shall accrue to
holders of Common Stock or Preferred Stock by reason of the fact that dividends
on said shares are not declared in any prior period.

        2. Liquidation Preference. In the event of any liquidation, dissolution
or winding up of the corporation (or the deemed occurrence of such event
pursuant to Section 2(e) below), either

                                      -2-
<PAGE>   3

voluntarily or involuntarily (a "Liquidation"), distributions to the
stockholders of the corporation shall be made in the following manner:

            (a) Series D Preferred and Series D-1 Preferred. The holders of the
Series D Preferred and Series D-1 Preferred shall be entitled to receive, prior
and in preference to any distribution of any of the assets or surplus funds of
the corporation to the holders of the Series A Preferred, Series A-1 Preferred,
Series B Preferred, Series B-1 Preferred, Series C Preferred, Series C-1
Preferred or Common Stock of the corporation, an amount equal to $5.75 per share
for each share of Series D Preferred or Series D-1 Preferred then so held, as
adjusted for stock splits, dividends, or recapitalizations, plus a further
amount equal to any dividends declared but unpaid on such shares. In lieu of
receiving such preferential amounts and the additional preferential amounts set
forth in Section 4(c) below, the holders of Series D Preferred and Series D-1
Preferred may elect to convert such Preferred Stock into Common Stock pursuant
to Section 4(a).

            If, upon such Liquidation, the assets of the corporation are
insufficient to provide for the cash payment of the full aforesaid preferential
amount to the holders of Series D Preferred and Series D-1 Preferred, such
assets as are available shall be distributed ratably among the holders of Series
D Preferred and Series D-1 Preferred in the proportion that the full
preferential amount each such holder is otherwise entitled to receive bears to
the full preferential amount all such holders are entitled to receive.

            (b) Series A Preferred, Series A-1 Preferred, Series B Preferred,
Series B-1 Preferred, Series C Preferred and Series C-1 Preferred. After payment
has been made to the holders of the Series D Preferred and Series D-1 Preferred
of the full preferential amount set forth in Section 2(a) above, the holders of
Series A Preferred, Series A-1 Preferred, Series B Preferred, Series B-1
Preferred, Series C Preferred and Series C-1 Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the corporation to the holders of Common Stock of the
corporation, an amount equal to $1.00 per share for each share of Series A
Preferred or Series A-1 Preferred then so held; an amount equal to $3.25 per
share for each share of Series B Preferred or Series B-1 Preferred then so held;
and an amount equal to $5.00 per share for each share of Series C Preferred or
Series C-1 Preferred then so held, in each case as adjusted for stock splits,
dividends, or recapitalizations, plus a further amount equal to any dividends
declared but unpaid on such shares. In lieu of receiving such preferential
amounts, the holders of Series A Preferred, Series A-1 Preferred, Series B
Preferred, Series B-1 Preferred, Series C Preferred and Series C-1 Preferred may
elect to convert such Preferred Stock into Common Stock pursuant to Section
4(a).

            If, upon such Liquidation, the assets of the corporation are
insufficient to provide for the cash payment of the full aforesaid preferential
amount to the holders of Series A Preferred, Series A-1 Preferred, Series B
Preferred, Series B-1 Preferred, Series C Preferred and Series C-1 Preferred,
such assets as are available after payment of the full preferential amount set
forth in Section 2(a) above, if any, shall be distributed ratably among the
holders of Series A Preferred, Series A-1 Preferred, Series B Preferred, Series
B-1 Preferred, Series C Preferred and Series C-1 Preferred in

                                      -3-
<PAGE>   4

the proportion that the full preferential amount each such holder is otherwise
entitled to receive bears to the full preferential amount all such holders are
entitled to receive.

            (c) Additional Series D Preferred and Series D-1 Preferred
Liquidation Preference. After payment has been made to the holders of Preferred
Stock of the full preferential amounts set forth in Sections 2(a) and 2(b)
above, the holders of Series D Preferred and Series D-1 Preferred shall be
entitled to receive, prior and in preference to any distribution of any of the
assets or surplus funds of the corporation to the holders of Common Stock of the
corporation, an additional amount equal to (i) $1.4375, plus (ii) $0.359 for the
first full twelve month period and $0.359 for each full three month period
thereafter that shall have elapsed since May 10, 1999 (but in no event shall the
total of (i) and (ii) exceed $5.75) per share for each share of Series D
Preferred or Series D-1 Preferred then so held, as adjusted for stock splits,
dividends, or recapitalizations.

            If, upon such Liquidation, the assets of the corporation are
insufficient to provide for the cash payment of the full aforesaid additional
preferential amount to the holders of Series D Preferred and Series D-1
Preferred, such assets as are available after payment of the full preferential
amounts set forth in Sections 2(a) and 2(b) above, if any, shall be distributed
ratably among the holders of Series D Preferred and Series D-1 Preferred in the
proportion that the full preferential amount each such holder is otherwise
entitled to receive bears to the full preferential amount all such holders are
entitled to receive.

            (d) Common Stock. All of the preferential amounts to be paid to the
holders of the Preferred Stock under Sections 2(a), 2(b) and 2(c) shall be paid
or set apart for payment before the payment or setting apart for payment of any
amount for, or the distribution of any assets of this corporation to, the
holders of the Common Stock in connection with such Liquidation. After the
payment or the setting apart of payment to the holders of the Preferred Stock of
the preferential amounts so payable to them, the holders of the Common Stock
shall be entitled to receive all remaining assets of the corporation.

            (e) Consolidation or Merger. A merger, consolidation or sale of all
or substantially all of the assets of the corporation which will result in the
corporation's stockholders immediately prior to such transaction not holding (by
virtue of such shares or securities issued solely with respect thereto) at least
50% of the voting power of the surviving, continuing or purchasing entity, shall
be deemed to be a Liquidation within the meaning of this Section 2; provided,
however, that any payments made may be made in cash or in securities or other
property received from the acquiring entity or in a combination thereof, on the
closing of such transaction.

            (f) Noncash Distributions. If any of the assets of the corporation
are to be distributed other than in cash under this Section 2 or for any
purpose, then the Board of Directors of the corporation shall promptly engage
independent competent appraisers to determine the value of the assets (other
than securities of the corporation) to be distributed to the holders of
Preferred Stock or Common Stock. The corporation shall, upon receipt of such
appraiser's valuation, give prompt written notice to each holder of shares of
Preferred Stock or Common Stock of the appraiser's

                                      -4-
<PAGE>   5

valuation. Notwithstanding the above, any securities to be distributed to the
stockholders shall be valued as follows:

               (i) If traded on a securities exchange, the value shall be deemed
to be the average of the closing prices of the securities on such exchange over
the 30-day period ending three (3) business days prior to the closing;

               (ii) If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid prices over the 30-day period ending
three (3) business days prior to the closing; and

               (iii) If there is no active public market, the value shall be the
fair market value thereof, as mutually determined by the corporation and the
holders of not less than a majority of the outstanding shares of Preferred
Stock, provided that if the corporation and the holders of a majority of the
outstanding shares of Preferred Stock are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the corporation,
but acceptable to the holders of a majority of the outstanding shares of
Preferred Stock

        3. Voting Rights.

            (a) Preferred Stock. Except as otherwise provided herein or required
by law, the holder of each share of Preferred Stock shall be entitled to vote on
all matters and shall be entitled to the number of votes equal to the number of
shares of Common Stock into which each share of Preferred Stock could be
converted pursuant to Section 4 hereof at the record date for the determination
of the stockholders entitled to vote on such matters or, if no such record date
is established, at the date such vote is taken. Except as otherwise provided
herein or required by law, the Preferred Stock shall have voting rights and
powers equal to the voting rights and powers of the Common Stock. Fractional
votes shall not, however, be permitted and any fractional voting rights
resulting from the above formula shall be rounded to the nearest whole number
(with one-half rounded upward to one).

            (b) Common Stock. Each holder of shares of Common Stock shall be
entitled to one vote for each share thereof held.

            (c) Election by Ballot. The election of directors need not be by
written ballot unless the Bylaws of the corporation shall so provide.

        4. Conversion. The holders of Preferred Stock shall have conversion
rights as follows (the "Conversion Rights"):

            (a) Right to Convert. Each share of Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share at the office of the corporation or any transfer agent
for such Preferred Stock. Each share of Preferred Stock shall be

                                      -5-
<PAGE>   6

convertible into the number of shares of Common Stock which results from
dividing the "Conversion Price" per share in effect for such series of Preferred
Stock at the time of conversion into the "Conversion Value" per share of such
series of Preferred Stock. The number of shares of Common Stock into which each
series of Preferred Stock is convertible is hereinafter collectively referred to
as the "Conversion Rate" for such series. The initial Conversion Price per share
of Series A Preferred and Series A-1 Preferred shall be $1.00. The initial
Conversion Price per share of Series B Preferred and Series B-1 Preferred shall
be $3.25. The initial Conversion Price per share of Series C Preferred and
Series C-1 Preferred shall be $5.00. The initial Conversion Price per share of
Series D Preferred and Series D-1 Preferred shall be $5.75. The Conversion Value
per share of Series A Preferred and Series A-1 Preferred shall be $1.00. The
Conversion Value per share of Series B Preferred and Series B-1 Preferred shall
be $3.25. The Conversion Value per share of Series C Preferred and Series C-1
Preferred shall be $5.00. The Conversion Value per share of Series D Preferred
and Series D-1 Preferred shall be $5.75. The Conversion Price of each series of
Preferred Stock shall be subject to adjustment as hereinafter provided.

            (b) Automatic Conversion. Each share of Preferred Stock shall
automatically be converted into shares of Common Stock at the then effective
Conversion Rate immediately upon the closing of a firm commitment underwritten
public offering pursuant to an effective registration statement under the
Securities Act of 1933, as amended, covering any of the corporation's Common
Stock (as that term is defined under the Securities Act of 1933, as then in
effect) with a sales price per share of Common Stock (as adjusted for
combinations, stock dividends, subdivisions or split-ups) of at least $6.50 and
with aggregate gross proceeds to the corporation, at the public offering price,
of at least $25,000,000. Each share of Series A Preferred, Series A-1 Preferred,
Series B Preferred, Series B-1 Preferred, Series C Preferred and Series C-1
Preferred shall automatically be converted into shares of Common Stock at the
then effective Conversion Rate immediately upon the approval (by vote or written
consent) of the holders of more than sixty-six and two-thirds percent (66 2/3%)
of the outstanding shares of such series of Preferred Stock, voting together as
a separate class. Each share of Series D Preferred and Series D-1 Preferred
shall automatically be converted into shares of Common Stock at the then
effective Conversion Rate immediately upon the approval (by vote or written
consent) of the holders of more than sixty-six and two-thirds percent (66 2/3%)
of the outstanding shares of such Series D Preferred and Series D-1 Preferred,
voting together as a separate class.

            (c) Mechanics of Conversion. Before any holder of Preferred Stock
shall be entitled to convert the same into shares of Common Stock, such holder
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the corporation or of any transfer agent for such Preferred Stock and
shall give written notice to the corporation at such office that such holder
elects to convert the same. The corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Preferred Stock a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Preferred Stock to be converted, and the person or
persons entitled to receive the

                                      -6-
<PAGE>   7

shares of Common Stock issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such shares of Common Stock on such
date.

            (d) Adjustments to Conversion Price of the Preferred Stock for
Dilutive Issues; Special Conversion of Series A Preferred, Series B Preferred,
Series C Preferred, and Series D Preferred:

               (i) Special Definitions. For purposes of this Section 4(d), the

Preferred Stock was first issued.

                    (C) "Convertible Securities" shall mean any evidences of
indebtedness, shares (other than the Common Stock) or other securities

                    (D) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 4(d)(iii), deemed to be
issued) by the corporation, other than:

                         (1) shares of the corporation's Common Stock issued
upon conversion of the Preferred Stock;

                         (2) shares issued pursuant to the acquisition of
another corporation by the corporation by merger, purchase of substantially all
of the assets, or other reorganization;

                         (3) up to 2,500,000 shares (as adjusted for stock
splits, stock dividends, or recapitalization) of the corporation's Common Stock
(or related options) issued to employees, officers, directors, consultants, or
other persons performing services for the corporation (including, but not by way
of limitation, distributors and sales representatives) pursuant to any stock
offering, plan, or arrangement and such additional shares issued to such persons
as approved by the unanimous written consent of the Board of Directors or the
unanimous vote of the members of the corporation's Board of Directors present
and voting at a duly held meeting;

                         (4) shares issued to financial institutions regularly

receivable or in connection with the lease of equipment and in both cases for
other than equity financing purposes; or

                         (5) shares of the corporation's Common Stock issued in
connection with any stock split, stock dividend, or recapitalization by the
corporation.

                    (E) "Pro Rata Share" with respect to each holder of
Preferred Stock shall mean that portion of the total dollar amount of the
Dilutive Issuance (as defined below) equal to (i) the amount of the Dilutive
Issuance actually offered to all holders of Preferred Stock by the Board of
Directors of the corporation (ii) multiplied by a fraction, the numerator of
which is the number of shares of Preferred Stock then held by such holder, and
the denominator of which is the total number of shares of Preferred Stock then
outstanding.

                    (F) "Dilutive Issuance" with respect to each series of
Preferred Stock shall mean an issuance of Additional Shares of Common Stock for
a consideration per share less than the Conversion Price of such series of
Preferred Stock in effect on the date of and immediately prior to such issuance.

                    (G) "Participating Investor" shall mean any holder of
Preferred Stock that purchases at least its Pro Rata Share of a Dilutive
Issuance.

                    (H) "Nonparticipating Investor" shall mean any holder of
Preferred Stock that is not a Participating Investor.

               (ii) Series A-1 Shadow Preferred.

                    (A) In the event the corporation proposes to undertake a
Dilutive Issuance, it shall give each holder of Series A Preferred a written
notice (the "Issuance Notice") of its intention, describing the type of new
securities, the price and number of shares and the general terms upon which the
corporation proposes to issue such new securities, at least thirty (30) days
prior to the date of such Dilutive Issuance. Each holder of Series A Preferred
may, within twenty (20) days from the date of the Issuance Notice, provide
written notice to the corporation that such holder agrees to become a
Participating Investor for the price and upon the terms specified in the
Issuance Notice. In the event that such holder fails to give such notice within
the twenty (20) day period, or fails to actually purchase its Pro Rata Share of
the Dilutive Issuance (other than as a result of the corporation refusing to
allow such holder to so purchase its Pro Rata Share), such holder shall be
deemed to be a Nonparticipating Investor.

                    (B) To the extent of the percentage of the Pro Rata Share
not purchased (the "Refused Percentage") by each Nonparticipating Investor, that
number of outstanding shares of Series A Preferred held by such Nonparticipating
Investor equal to the product of (x) the number of shares of such series held by
the Nonparticipating Investor, times (y) the Refused Percentage, shall be
converted automatically on the date (the "Closing Date") of the applicable

                                      -8-
<PAGE>   9

Dilutive Issuance (provided that the corporation gave the Issuance Notice to
such holder of Series A Preferred) into an equal number of fully-paid and
nonassessable shares of Series A-1 Preferred; provided, however, that prior to
the Closing Date each Nonparticipating Investor shall have the right to convert
such shares of Series A Preferred into shares of Common Stock at the Conversion
Rate in effect for such series as of the date of such conversion.

                    (C) Upon the conversion of Series A Preferred held by a
Nonparticipating Investor as set forth herein, such shares of Series A Preferred
shall no longer be outstanding on the books of the corporation and may not be
reissued, and the Nonparticipating Investor shall be treated for all purposes as
the record holder of such shares of Series A-1 Preferred on the Closing Date. No
shares of Series A-1 Preferred shall be issued except as set forth in this
Section 4(d)(ii) upon conversion of shares of Series A Preferred.

                    (D) No adjustment in the Conversion Price of the Series A-1
Preferred shall be made in respect of the issuance of Additional Shares of
Common Stock, regardless of the issuance price of such shares, except for the
issuance of such shares as a stock dividend, stock split, or in connection with
such other transaction as provided in paragraph 4(e) hereof.

                    (E) In the event that any shares of Series A-1 Preferred are
issued, concurrently with such issuance, the corporation shall take all such
action as may be required, including amending the Certificate of Incorporation,
(1) to cancel all authorized shares of Series A-1 Preferred Stock that remain
unissued after such issuance, (2) to create and reserve for issuance upon any
subsequent Dilutive Issuance a new series of Preferred Stock equal in number to
the number of shares of Series A-1 Preferred so canceled and designated Series
A-2 Preferred, with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series A Preferred, except that the Conversion Price for such shares of
Series A-2 Preferred once initially issued shall be the Conversion Price in
effect immediately prior to such Dilutive Issuance and shall no longer be
subject to adjustment in respect of the issuance of Additional Shares of Common
Stock, except for the issuance of such shares as a stock dividend, stock split,
or in connection with such other transaction as provided in paragraph 4(e)
hereof, and (3) to amend the provisions of this Section 4 to provide that any
subsequent conversion of Series A Preferred upon a Dilutive Issuance will be
into shares of Series A-2 Preferred rather than Series A-1 Preferred. The
corporation shall take the same actions with respect to the Series A-2 Preferred
and each subsequently authorized series of Preferred Stock upon initial issuance
of shares of the last such series to be authorized.

               (iii) Series B-1 Shadow Preferred.

                    (A) In the event the corporation proposes to undertake a
Dilutive Issuance, it shall give each holder of Series B Preferred an Issuance
Notice, describing the type of new securities, the price and number of shares
and the general terms upon which the corporation proposes to issue such new
securities, at least thirty (30) days prior to the date of such Dilutive
Issuance. Each holder of Series B Preferred may, within twenty (20) days from
the date of the

                                      -9-
<PAGE>   10

Issuance Notice, provide written notice to the corporation that such holder
agrees to become a Participating Investor for the price and upon the terms
specified in the Issuance Notice. In the event that such holder fails to give
such notice within the twenty (20) day period, or fails to actually purchase its
Pro Rata Share of the Dilutive Issuance (other than as a result of the
corporation refusing to allow such holder to so purchase its Pro Rata Share),
such holder shall be deemed to be a Nonparticipating Investor.

                    (B) To the extent of the Refused Percentage by each
Nonparticipating Investor, that number of outstanding shares of Series B
Preferred held by such Nonparticipating Investor equal to the product of (x) the
number of shares of such series held by the Nonparticipating Investor, times (y)
the Refused Percentage, shall be converted automatically on the Closing Date of
the applicable Dilutive Issuance (provided that the corporation gave the
Issuance Notice to such holder of Series B Preferred) into an equal number of
fully-paid and nonassessable shares of Series B-1 Preferred; provided, however,
that prior to the Closing Date each Nonparticipating Investor shall have the
right to convert such shares of Series B Preferred into shares of Common Stock
at the Conversion Rate in effect for such series as of the date of such
conversion.

                    (C) Upon the conversion of Series B Preferred held by a
Nonparticipating Investor as set forth herein, such shares of Series B Preferred
shall no longer be outstanding on the books of the corporation and may not be
reissued, and the Nonparticipating Investor shall be treated for all purposes as
the record holder of such shares of Series B-1 Preferred on the Closing Date. No
shares of Series B-1 Preferred shall be issued except as set forth in this
Section 4(d)(iii) upon conversion of shares of Series B Preferred.

                    (D) No adjustment in the Conversion Price of the Series B-1
Preferred shall be made in respect of the issuance of Additional Shares of
Common Stock, regardless of the issuance price of such shares, except for the
issuance of such shares as a stock dividend, stock split, or in connection with
such other transaction as provided in paragraph 4(e) hereof.

                    (E) In the event that any shares of Series B-1 Preferred are
issued, concurrently with such issuance, the corporation shall take all such
action as may be required, including amending the Certificate of Incorporation,
(1) to cancel all authorized shares of Series B-1 Preferred Stock that remain
unissued after such issuance, (2) to create and reserve for issuance upon any
subsequent Dilutive Issuance a new series of Preferred Stock equal in number to
the number of shares of Series B-1 Preferred so cancelled and designated Series
B-2 Preferred, with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series B Preferred, except that the Conversion Price for such shares of
Series B-2 Preferred once initially issued shall be the Conversion Price in
effect immediately prior to such Dilutive Issuance and shall no longer be
subject to adjustment in respect of the issuance of Additional Shares of Common
Stock, except for the issuance of such shares as a stock dividend, stock split,
or in connection with such other transaction as provided in paragraph 4(e)
hereof, and (3) to amend the provisions of this Section 4 to provide that any
subsequent conversion of Series B Preferred upon a Dilutive Issuance will be
into shares of Series B-2 Preferred rather than

                                      -10-
<PAGE>   11

Series B-1 Preferred. The corporation shall take the same actions with respect
to the Series B-2 Preferred and each subsequently authorized series of Preferred
Stock upon initial issuance of shares of the last such series to be authorized.

               (iv) Series C-1 Shadow Preferred.

                    (A) In the event the corporation proposes to undertake a
Dilutive Issuance, it shall give each holder of Series C Preferred an Issuance
Notice, describing the type of new securities, the price and number of shares
and the general terms upon which the corporation proposes to issue such new
securities, at least thirty (30) days prior to the date of such Dilutive
Issuance. Each holder of Series C Preferred may, within twenty (20) days from
the date of the Issuance Notice, provide written notice to the corporation that
such holder agrees to become a Participating Investor for the price and upon the
terms specified in the Issuance Notice. In the event that such holder fails to
give such notice within the twenty (20) day period, or fails to actually
purchase its Pro Rata Share of the Dilutive Issuance (other than as a result of
the corporation refusing to allow such holder to so purchase its Pro Rata
Share), such holder shall be deemed to be a Nonparticipating Investor.

                    (B) To the extent of the Refused Percentage by each
Nonparticipating Investor, that number of outstanding shares of Series C
Preferred held by such Nonparticipating Investor equal to the product of (x) the
number of shares of such series held by the Nonparticipating Investor, times (y)
the Refused Percentage, shall be converted automatically on the Closing Date of
the applicable Dilutive Issuance (provided that the corporation gave the
Issuance Notice to such holder of Series C Preferred) into an equal number of
fully-paid and nonassessable shares of Series C-1 Preferred; provided, however,
that prior to the Closing Date each Nonparticipating Investor shall have the
right to convert such shares of Series C Preferred into shares of Common Stock
at the Conversion Rate in effect for such series as of the date of such
conversion.

                    (C) Upon the conversion of Series C Preferred held by a
Nonparticipating Investor as set forth herein, such shares of Series C Preferred
shall no longer be outstanding on the books of the corporation and may not be
reissued, and the Nonparticipating Investor shall be treated for all purposes as
the record holder of such shares of Series C-1 Preferred on the Closing Date. No
shares of Series C-1 Preferred shall be issued except as set forth in this
Section 4(d)(iv) upon conversion of shares of Series C Preferred.

                    (D) No adjustment in the Conversion Price of the Series C-1
Preferred shall be made in respect of the issuance of Additional Shares of
Common Stock, regardless of the issuance price of such shares, except for the
issuance of such shares as a stock dividend, stock split, recapitalization or in
connection with such other transaction as provided in paragraph 4(e) hereof.

                    (E) In the event that any shares of Series C-1 Preferred are
issued, concurrently with such issuance, the corporation shall take all such
action as may be required,

                                      -11-
<PAGE>   12

including amending the Certificate of Incorporation, (1) to cancel all
authorized shares of Series C-1 Preferred Stock that remain unissued after such
issuance, (2) to create and reserve for issuance upon any subsequent Dilutive
Issuance a new series of Preferred Stock equal in number to the number of shares
of Series C-1 Preferred so cancelled and designated Series C-2 Preferred, with
the designations, powers, preferences and rights and the qualifications,
limitations and restrictions identical to those then applicable to the Series C
Preferred, except that the Conversion Price for such shares of Series C-2
Preferred once initially issued shall be the Conversion Price in effect
immediately prior to such Subsequent Dilutive Issuance and shall no longer be
subject to adjustment in respect of the issuance of Additional Shares of Common
Stock, except for the issuance of such shares as a stock dividend, stock split,
or in connection with such other transaction as provided in paragraph 4(e)
hereof, and (3) to amend the provisions of this Section 4 to provide that any
subsequent conversion of Series C Preferred upon a Dilutive Issuance will be
into shares of Series C-2 Preferred rather than Series C-1 Preferred. The
corporation shall take the same actions with respect to the Series C-2 Preferred
and each subsequently authorized series of Preferred Stock upon initial issuance
of shares of the last such series to be authorized.

               (v) Series D-1 Shadow Preferred.

                    (A) In the event the corporation proposes to undertake a
Dilutive Issuance, it shall give each holder of Series D Preferred an Issuance
Notice, describing the type of new securities, the price and number of shares
and the general terms upon which the corporation proposes to issue such new
securities, at least thirty (30) days prior to the date of such Dilutive
Issuance. Each holder of Series D Preferred may, within twenty (20) days from
the date of the Issuance Notice, provide written notice to the corporation that
such holder agrees to become a Participating Investor for the price and upon the
terms specified in the Issuance Notice. In the event that such holder fails to
give such notice within the twenty (20) day period, or fails to actually
purchase its Pro Rata Share of the Dilutive Issuance (other than as a result of
the corporation refusing to allow such holder to so purchase its Pro Rata
Share), such holder shall be deemed to be a Nonparticipating Investor.

                    (B) To the extent of the Refused Percentage by each
Nonparticipating Investor, that number of outstanding shares of Series D
Preferred held by such Nonparticipating Investor equal to the product of (x) the
number of shares of such series held by the Nonparticipating Investor, times (y)
the Refused Percentage, shall be converted automatically on the Closing Date of
the applicable Dilutive Issuance (provided that the corporation gave the
Issuance Notice to such holder of Series D Preferred) into an equal number of
fully-paid and nonassessable shares of Series D-1 Preferred; provided, however,
that prior to the Closing Date each Nonparticipating Investor shall have the
right to convert such shares of Series D Preferred into shares of Common Stock
at the Conversion Rate in effect for such series as of the date of such
conversion.

                    (C) Upon the conversion of Series D Preferred held by a
Nonparticipating Investor as set forth herein, such shares of Series D Preferred
shall no longer be outstanding on the books of the corporation and may not be
reissued, and the Nonparticipating

                                      -12-
<PAGE>   13

Investor shall be treated for all purposes as the record holder of such shares
of Series D-1 Preferred on the Closing Date. No shares of Series D-1 Preferred
shall be issued except as set forth in this Section 4(d)(v) upon conversion of
shares of Series D Preferred.

                    (D) No adjustment in the Conversion Price of the Series D-1
Preferred shall be made in respect of the issuance of Additional Shares of
Common Stock, regardless of the issuance price of such shares, except for the
issuance of such shares as a stock dividend, stock split, recapitalization or in
connection with such other transaction as provided in paragraph 4(e) hereof.

                    (E) In the event that any shares of Series D-1 Preferred are
issued, concurrently with such issuance, the corporation shall take all such
action as may be required, including amending the Certificate of Incorporation,
(1) to cancel all authorized shares of Series D-1 Preferred Stock that remain
unissued after such issuance, (2) to create and reserve for issuance upon any
subsequent Dilutive Issuance a new series of Preferred Stock equal in number to
the number of shares of Series D-1 Preferred so cancelled and designated Series
D-2 Preferred, with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series D Preferred, except that the Conversion Price for such shares of
Series D-2 Preferred once initially issued shall be the Conversion Price of
Series D-1 Preferred in effect immediately prior to such Subsequent Dilutive
Issuance and shall no longer be subject to adjustment in respect of the issuance
of Additional Shares of Common Stock, except for the issuance of such shares as
a stock dividend, stock split, or in connection with such other transaction as
provided in paragraph 4(e) hereof, and (3) to amend the provisions of this
Section 4 to provide that any subsequent conversion of Series D Preferred upon a
Dilutive Issuance will be into shares of Series D-2 Preferred rather than Series
D-1 Preferred. The corporation shall take the same actions with respect to the
Series D-2 Preferred and each subsequently authorized series of Preferred Stock
upon initial issuance of shares of the last such series to be authorized.

               (vi) Deemed Issue of Additional Shares of Common Stock. In the
event the corporation at any time or from time to time after the Original Issue
Date in respect of a series of Preferred Stock shall issue any Options or
Convertible Securities or shall fix a record date for the determination of
holders of any class of securities entitled to receive any such Options or
Convertible Securities, then the maximum number of shares (as set forth in the
instrument relating thereto assuming the satisfaction of any conditions to
exercisability, including, without limitation, the passage of time and without
regard to any provisions contained therein for a subsequent adjustment of such
number) of Common Stock issuable upon the exercise of such Options or, in the
case of Convertible Securities and Options therefor, the conversion or exchange
of such Convertible Securities, shall be deemed to be Additional Shares of
Common Stock issued as of the time of such issue or, in case such a record date
shall have been fixed, as of the close of business on such record date, provided
that Additional Shares of Common Stock shall not be deemed to have been issued
with respect to a series of Preferred Stock unless the consideration per share
(determined pursuant to Section 4(d)(viii) hereof) of such Additional Shares of
Common Stock would be less than the Conversion Price for such series of
Preferred Stock in effect on the date of and immediately prior to

                                      -13-
<PAGE>   14

such issue, or such record date, as the case may be, and provided further that
in any such case in which Additional Shares of Common Stock are deemed to be
issued:

                    (A) no further adjustment in the Conversion Price shall be
made upon the subsequent issue of Convertible Securities or shares of Common
Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                    (B) if such Options or Convertible Securities by their terms
provide, with the passage of time or otherwise, for any increase or decrease in
the consideration payable to the corporation, or in the number of shares of
Common Stock issuable, upon the exercise, conversion or exchange thereof, the
Conversion Price computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                    (C) upon the expiration of any such Options or any rights of
conversion or exchange under such Convertible Securities which shall not have
been exercised, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon such expiration, be recomputed
as if:

                         (1) in the case of Convertible Securities or Options
for Common Stock, the only Additional Shares of Common Stock issued were shares
of Common Stock, if any, actually issued upon the exercise of such Options or
the conversion or exchange of such Convertible Securities and the consideration
received therefor was the consideration actually received by the corporation for
the issue of all such Options, whether or not exercised, plus the consideration
actually received by the corporation upon such exercise, or for the issue of all
such Convertible Securities which were actually converted or exchanged, plus the
additional consideration, if any, actually received by the corporation upon such
conversion or exchange, and

                         (2) in the case of Options for Convertible Securities,
only the Convertible Securities, if any, actually issued upon the exercise
thereof were issued at the time of issue of such Options, and the consideration
received by the corporation for the Additional Shares of Common Stock deemed to
have been then issued was the consideration actually received by the corporation
for the issue of all such Options, whether or not exercised, plus the
consideration deemed to have been received by the corporation upon the issue of
the Convertible Securities with respect to which such Options were actually
exercised;

                    (D) no readjustment pursuant to clause (B) or (C) above
shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (i) the Conversion Price on the original adjustment date,
or (ii) the Conversion Price that would have

                                      -14-
<PAGE>   15

resulted from any issuance of Additional Shares of Common Stock between the
original adjustment date and such readjustment date; and

                    (E) in the case of any Options which expire by their terms
not more than 90 days after the date of issue thereof, no adjustment of the
Conversion Price shall be made until the expiration or exercise of all such
Options.

               (vii) Adjustment of Conversion Price Upon Issuance of Additional
Shares of Common Stock. In the event this corporation shall issue Additional
Shares of Common Stock (including Additional Shares of Common Stock deemed to be
issued pursuant to Section 4(d)(vi)) after the Original Issue Date without
consideration or for consideration per share less than the Conversion Price for
Series A Preferred, Series B Preferred, Series C Preferred or Series D Preferred
in effect on the date of and immediately prior to such issue, then and in such
event, the Conversion Price for such series of Preferred Stock shall be reduced,
concurrently with such issue, to a price determined by multiplying such
Conversion Price by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issue (including
all shares of Common Stock issuable upon conversion of the outstanding Preferred
Stock) plus the number of shares of Common Stock which the aggregate
consideration received by the corporation for the total number of Additional
Shares of Common Stock so issued would purchase at such Conversion Price; and
the denominator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issue (including all shares of Common
Stock issuable upon conversion of the outstanding Preferred Stock) plus the
number of such Additional Shares of Common Stock so issued.

               (viii) Determination of Consideration. For purposes of this
Section 4(d), the consideration received by the corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                    (A) Cash and Property. Such consideration shall:

                         (1) insofar as it consists of cash, be computed at the
aggregate amount of cash received by the corporation excluding amounts paid or
payable for accrued interest or accrued dividends;

                         (2) insofar as it consists of property other than cash,
be computed at the fair value thereof at the time of such issue, as determined
in good faith by the Board irrespective of any accounting treatment; and

                         (3) in the event Additional Shares of Common Stock are
issued together with other shares or securities or other assets of the
corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (1) and (2) above, as
determined in good faith by the Board.

                                      -15-
<PAGE>   16

                    (B) Options and Convertible Securities. The consideration
per share received by the corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Section 4(d)(vi), relating to Options and
Convertible Securities, shall be determined by dividing

                         (x) the total amount, if any, received or receivable by
the corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities by

                         (y) the maximum number of shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

            (e) Adjustment of Conversion Price. The Conversion Price of each
series of Preferred Stock shall be subject to adjustment from time to time as
follows:

               (i) If the number of shares of Common Stock outstanding at any
time after the date hereof is increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then, on
the date such payment is made or such change is effective, the Conversion Price
for each series of Preferred Stock shall be appropriately decreased so that the
number of shares of Common Stock issuable on conversion of shares of such series
of Preferred Stock shall be increased in proportion to such increase of
outstanding shares.

               (ii) If the number of shares of Common Stock outstanding at any
time after the date hereof is decreased by a combination or reverse stock split
of the outstanding shares of Common Stock, then, on the effective date of such
combination, the Conversion Price for each series of Preferred Stock shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of shares of such series of Preferred Stock shall be decreased in
proportion to such decrease in outstanding shares.

               (iii) In case, at any time after the date hereof, of any capital
reorganization or any reclassification of the stock of the corporation (other
than a change in par value or as a result of a stock dividend or subdivision,
split-up, reverse stock split, or combination of shares), the shares of each
series of Preferred Stock shall, after such reorganization or reclassification,
be convertible into the kind and number of shares of stock or other securities
or property of the corporation to which such holder would have been entitled if
immediately prior to such reorganization or reclassification such holder had
converted its shares of such series of Preferred Stock into Common

                                      -16-
<PAGE>   17

Stock. The provisions of this Section 4(e)(iii) shall similarly apply to
successive reorganizations or reclassifications.

            (f) Fractional Shares. No fractional shares of Common Stock shall be
issued upon conversion of the Preferred Stock. In lieu of any fractional shares
to which the holder would otherwise be entitled, the corporation shall pay cash
equal to such fraction multiplied by the fair market value for such Common Stock
as determined in accordance with Section 2(c).

            (g) Adjustment Threshold and Recording. No adjustment in a
Conversion Price need be made if such adjustment would result in a change in a
Conversion Price of less than $0.01. Any adjustment of less than $0.01 which is
not made shall be carried forward and shall be made at the time of and together
with any subsequent adjustment which, on a cumulative basis, amounts to an
adjustment of $0.01 or more in a Conversion Price. All calculations under this
Section 4 shall be made to the nearest one hundredth of a cent ($0.0001) or to
the nearest one hundredth (1/100) of a share, as the case may be.

            (h) Other Distributions. In the event this corporation shall declare
a distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets excluding cash dividends or
options or rights not referred to in subsection 4(e), then in each such case for
the purpose of this subsection 4(h), the holders of Preferred Stock shall be
entitled to a proportionate share of any such distribution as though they were
the holders of the number of shares of Common Stock of the corporation into
which their shares of Preferred Stock are convertible as of the record date
fixed for the determination of the holders of Common Stock of the corporation
entitled to receive such distribution.

            (i) No Impairment. The corporation will not, through any
reorganization, transfer of assets, consolidation, merger, dissolution,
recapitalization, tender offer, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of
Preferred Stock against impairment. This provision shall not restrict the
corporation from amending its Certificate of Incorporation in accordance with
(A) the General Corporation Law of the State of Delaware and (B) the applicable
consent and voting provisions stated herein.

            (j) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price pursuant to this Section 4,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The corporation shall, upon written request at any time
of any holder of Preferred Stock, furnish or cause to be furnished to such
holder a like certificate setting forth (i) such adjustments and readjustments,
(ii) the Conversion Price at the time in effect for each series of Preferred
Stock, and

                                      -17-
<PAGE>   18

(iii) the number of shares of Common Stock and the amount, if any, of other
property which at the time would be received upon the conversion of the
Preferred Stock held by such holder.

            (k) Notices of Record Date. In the event of any taking by the
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, the corporation
shall mail to each holder of Preferred Stock at least twenty (20) days prior to
the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend or distribution.

            (l) Reservation of Stock Issuable Upon Conversion. The corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock solely for the purpose of effecting the conversion of the
shares of Preferred Stock such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
shares of Preferred Stock; and if at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the conversion
of all then outstanding shares of Preferred Stock, the corporation will take
such corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purpose, subject to such stockholder
approval as may be required.

            (m) Status of Converted Stock. In the event any shares of Series A
Preferred, Series A-1 Preferred, Series B Preferred, Series B-1 Preferred,
Series C Preferred, Series C-1 Preferred, Series D Preferred, or Series D-1
Preferred shall be converted pursuant to Section 4 hereof, the shares so
converted shall be canceled and shall not be issuable by the corporation. The
Certificate of Incorporation of this corporation shall be appropriately amended
to effect the corresponding reduction in the corporation's authorized capital
stock.

            (n) Notices. Any notice required by the provisions of this Section 4
to be given to the holder of shares of Preferred Stock shall be deemed given if
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at its address appearing on the books of the corporation.

        5 Protective Provisions.

            (a) So long as 500,000 shares of the Series A Preferred or Series

                                      -20-

permitted by Section 145. The corporation shall promptly make or cause to be
made any determination required to be made pursuant to Section 145.

            (b) No person shall be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided, however, that the foregoing shall not eliminate or limit the liability
of a director (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the General Corporation Law of the State of Delaware or (iv) for
any transaction from which the director derived an improper personal benefit. If
the General Corporation Law of the State of Delaware is subsequently amended to
further eliminate or limit the liability of a director, then a director of the
corporation, in addition to the circumstances in which a director is not
personally liable as set forth in the preceding sentence, shall not be liable to
the fullest extent permitted by the amended General Corporation Law of the State
of Delaware. For purposes of this Article NINE, "fiduciary duty as a director"
shall include any fiduciary duty arising out of serving at the corporation's
request as a director of another corporation, partnership, joint venture or
other enterprise, and "personal liability to the corporation or its
stockholders" shall include any liability to such other corporation,
partnership, joint venture, trust or other enterprise, and any liability to the
corporation in its capacity as a security holder, joint venturer, partner,
beneficiary, creditor or investor of or in any such other corporation,
partnership, joint venture, trust or other enterprise.

            (c) Neither any amendment nor repeal of this Article NINE, nor the
adoption of any provision of this Certificate of Incorporation inconsistent with
this Article NINE, shall eliminate or reduce the effect of this Article NINE in
respect of any matter occurring, or any cause of action,

                                      -21-

suit or claim that, but for this Article NINE, would accrue or arise, prior to
such amendment, repeal or adoption of an inconsistent provision.

        TEN. Advance notice of new business and stockholder nominations for the
election of directors shall be given in the manner and to the extent provided in
the Bylaws of the corporation.

        ELEVEN. Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this corporation under the provisions of Section 279 of Title 8 of the
Delaware Code, order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this corporation, as the case may be,
and also on this corporation.

        TWELVE. Subject to the General Corporation Law of the State of Delaware
and Section 5 hereof, the corporation reserves the right to amend, alter, change
or repeal any provisions contained in this Certificate, in the manner now or
hereafter prescribed by statute, and all rights conferred upon stockholders
herein are granted subject to this reservation.

                          ARGONAUT TECHNOLOGIES, INC.

                                   ARTICLE 1

                               CORPORATE OFFICES


     1.1  REGISTERED OFFICE

     The registered office of the corporation shall be in the City of
Wilmington, County of New Castle, State of Delaware. The name of the registered
agent of the corporation at such location is The Corporation Trust Company.

     1.2  OTHER OFFICES

     The board of directors may at any time establish other offices at any
place or places where the corporation is qualified to do business.



                                   ARTICLE 2

                            MEETINGS OF STOCKHOLDERS

     2.1  PLACE OF MEETINGS

     Meetings of stockholders shall be held at any place, within or outside the
State of Delaware, designated by the board of directors. In the absence of any
such designation, stockholders' meetings shall be held at the registered office
of the corporation.

     2.2  ANNUAL MEETING

     The annual meeting of stockholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such
designation the annual meeting of shareholders shall be held on the second
Tuesday of May of each year at 10:00 a.m. However, if such day falls on a legal
holiday, then the meeting shall be held at the same time and place on the next
succeeding business day. At the meeting, directors shall be elected and any
other proper business may be transacted.

     2.3  SPECIAL MEETING

     A special meeting of the stockholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president, or by
one or more stockholders holding shares in


<PAGE>   6
the aggregate entitled to cast not less than ten percent of the votes at that
meeting.

     If a special meeting is called by any person or persons other than the
board of directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the chairman of the board, the president or the
secretary of the corporation. No business may be transacted at such special
meeting otherwise than specified in such notice. The officer receiving the
request shall cause notice to be promptly given to the stockholders entitled to
vote, in accordance with the provisions of Sections 2.4 and 2.5 of this Article
II, that a meeting will be held at the time requested by the person or persons
calling the meeting, not less than ten (10) nor more than sixty (60) days after
the receipt of the request. Nothing contained in this paragraph of this Section
2.3 shall be construed as limiting, fixing, or affecting the time when a
meeting of stockholders called by action of the board of directors may be held.

     2.4  NOTICE OF STOCKHOLDERS' MEETINGS

     All notices of meetings with stockholders shall be in writing and shall be
sent or otherwise given in accordance with Section 2.5 of these bylaws not less
than ten (10) nor more than sixty (60) days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notice shall specify the
place, date, and hour of the meeting, and, in the case of a special meeting,
the purpose or purposes for which the meeting is called.

     2.5  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

     Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the Secretary or an Assistant Secretary or of the transfer agent
of the corporation that the notice has been given shall, in the absence of
fraud, be prima facie evidence of the facts stated therein.

     2.6 QUORUM

     The holders of a majority of the stock issued and outstanding and entitled
to vote thereat, present in person or represented by proxy, shall constitute a
quorum at all meetings of the stockholders for the transaction of business
except as otherwise provided by statute or by the certificate of incorporation.
If, however, such quorum is not present or represented at any meeting of the
stockholders, then either (i) the Chairman of the meeting or (ii) the
stockholders entitled to vote thereat, present in person



                                      -2-

<PAGE>   7

or represented by proxy, shall have power to adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum is
present or represented. At such adjourned meeting at which a quorum is present
or represented, any business may be transacted that might have been transacted
at the meeting as originally noticed.

     2.7  ADJOURNED MEETING: NOTICE

     When a meeting is adjourned to another time or place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the
time and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

     2.8  CONDUCT OF BUSINESS

     The chairman of any meeting of stockholders shall determined the order of
business and the procedure at the meeting, including such regulation of the
manner of voting and the conduct of business.

     2.9  VOTING

     The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.12 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation
Law of Delaware (relating to voting rights of fiduciaries, pledgers and joint
owners of stock and to voting trusts and other voting agreements).

     Except as provided in the last paragraph of this Section 2.9, or as may be
otherwise provided in the certificate of incorporation, each stockholder shall
be entitled to one vote for each share of capital stock held by such
stockholder.

     At a stockholders' meeting at which directors are to be elected, each
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes which such stockholder
normally is entitled to cast) if the candidates' names have been properly
placed in nomination (in accordance with these bylaws) prior to commencement of
the voting and the stockholder requesting cumulative voting or any other
stockholder voting at the meeting in person or by proxy has given notice prior
to commencement of the voting of the stockholder's intention to cumulate votes.
If cumulative voting is



                                      -3-
<PAGE>   8
properly requested, each holder of stock, or of any class or classes or of a
series or series thereof, who elects to cumulate votes shall be entitled to as
many votes as equals the number of votes which (absent this provision as to
cumulative voting) he would be entitled to cast for the election of directors
with respect to his shares of stock multiplied by the number of directors to be
elected by him, and he may cast all of such votes for a single director or may
distribute them among the number to be voted for, or for any two or more of
them, as he may see fit.

     2.10 WAIVER OF NOTICE

     Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

     2.11 STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

     Unless otherwise provided in the certificate of incorporation, any action
required by this chapter to be taken at any annual or special meeting of
stockholders of a corporation, or any action that may be taken at any annual or
special meeting of such stockholders, may be taken without a meeting, without
prior notice, and without a vote if a consent in writing, setting forth the
action so taken, is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all shares entitled to vote thereon were
present and voted.

     Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. If the action which is consented to is such as
would have required the filing of a certificate under any section of the
General Corporation Law of Delaware if such action had been voted on by
stockholders at a meeting thereof, then the certificate filed under such
section shall state, in lieu of any statement required by such section
concerning any vote of stockholders, that written notice and written consent
have been given as provided in Section 228 of the General Corporation Law of
Delaware.

     2.12 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

     In order that the corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
or entitled to express consent to corporate action in writing without a
meeting, or entitled to receive payment of any dividend or other distribution
or allotment of any rights, or entitled to exercise any rights in respect of
any change, conversion or exchange of stock or for the purpose of any other
lawful action, the board of directors may fix, in advance, a record date, which
shall not be more than sixty (60) nor less than ten (10) days before the date
of such meeting, nor more than sixty (60) days prior to any other action.

     If the board of directors does not so fix a record date:

          The record date for determining stockholders entitled to notice of or
to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived,
at the close of business on the day next preceding the day on which the meeting
is held.

          (i)  The record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the board of directors is necessary, shall be the day on which the first
written consent is expressed.

          (ii) The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the board of
directors adopts the resolution relating thereto.

     A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the board of directors may fix a new record date for
the adjourned meeting.

     2.13 PROXIES

     Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for him by a written proxy, signed
by the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period. A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the stockholder or the

Law of Delaware.

     2.14  LIST OF STOCKHOLDERS ENTITLED TO VOTE

     The officer who has charge of the stock ledger of a corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present. Such list shall
presumptively determine the identity of the stockholders entitled to vote at the
meeting and the number of shares held by each of them.

                                   ARTICLE 3

                                   DIRECTORS

     3.1  POWERS

     Subject to the provisions of the General Corporation Law of Delaware and
any limitations in the certificate of incorporation or these bylaws relating to
action required to be approved by the stockholders or by the outstanding
shares, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the board of
directors.

     3.2  NUMBER OF DIRECTORS

     The board of directors shall consist of one (1) or more members, the
number thereof to be determined from time to time by resolution of the board of
directors.

     No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

<PAGE>   11

        3.3     ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

        Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Directors need not be stockholders unless so required by the
certificate of incorporation or these bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to
fill a vacancy, shall hold office until his successor is elected and qualified
or until his earlier resignation or removal.

        Elections of directors need not be by written ballot.

        3.4     RESIGNATION AND VACANCIES

        Any director may resign at any time upon written notice to the
attention of the Secretary of the corporation. When one or more directors so
resigns and the resignation is effective at a future date, a majority of the
directors then in office, including those who have so resigned, shall have
power to fill such vacancy or vacancies, the vote thereon to take effect when
such resignation or resignations shall become effective, and each director so
chosen shall hold office as provided in this section in the filling of other
vacancies.

        Unless otherwise provided in the certificate of incorporation or these
bylaws:

                (i)     Vacancies and newly created directorships resulting
from any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

                (ii)    Whenever the holders of any class or classes of stock
or series thereof are entitled to elect one or more directors by the provisions
of the certificate of incorporation, vacancies and newly created directorships
of such class or classes or series may be filled by a majority of the directors
elected by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

        If any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an


                                      -7-
<PAGE>   12
election as provided in Section 211 of the General Corporation Law of Delaware.

      If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole board
(as constituted immediately prior to any such increase), then the Court of
Chancery may, upon application of any stockholder or stockholders holding at
least ten (10) percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as
aforesaid, which election shall be governed by the provisions of Section 211 of
the General Corporation Law of Delaware as far as applicable.

      3.5   PLACE OR MEETINGS; MEETINGS BY TELEPHONE

      The board of directors of the corporation may hold meetings, both regular
and special, either within or outside the State of Delaware.

      Unless otherwise restricted by the certificate of incorporation or these
bylaws, members of the board of directors, or any committee designated by the
board of directors, may participate in a meeting of the board of directors, or
any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in
person at the meeting.

      3.6   REGULAR MEETINGS

      Regular meetings of the board of directors may be held without notice at
such time and at such place as shall from time to time be determined by the
board.

      3.7   SPECIAL MEETINGS; NOTICE

      Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two (2) directors.

      Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's
address as it is shown on the records of the corporation. If the notice is
mailed, it shall be deposited in the United States mail at least four (4) days
before the time of the holding of the meeting. If the notice is delivered
personally


                                      -8-

<PAGE>   13
or by telephone or by telegram, it shall be delivered personally or by
telephone or to the telegraph company at least forty-eight (48) hours before
the time of the holding of the meeting. Any oral notice given personally or by
telephone may be communicated either to the director or to a person at the
office of the director who the person giving the notice has reason to believe
will promptly communicate it to the director. The notice need not specify the
purposes or the place of the meeting, if the meeting is to be held at the
principal executive office of the corporation.

     3.8  QUORUM

     At all meetings of the board of directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business
and the act of a majority of the directors present at any meeting at which
there is a quorum shall be the act of the board of directors, except as may be
otherwise specifically provided by statute or by the certificate of
incorporation. If a quorum is not present at any meeting of the board of
directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

     A meeting at which a quorum is initially present may continue to
transaction business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.9  WAIVER OF NOTICE

     Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the directors, or members of a committee of directors, need be specified in
any written waiver of notice unless so required by the certificate of
incorporation or these bylaws.

     3.10 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

     Unless otherwise restricted by the certificate of incorporation or these
bylaws, any action required or permitted to be taken at any meeting of the
board of directors, or of any committee thereof, may be taken without a meeting
if all members of the board

                                      -9-
<PAGE>   14

or committee, as the case may be, consent thereto in writing and the writing or
writings are filed with the minutes of proceedings of the board or committee.

     3.11 FEES AND COMPENSATION OF DIRECTORS

     Unless otherwise restricted by the certificate of incorporation or these
bylaws, the board of directors shall have the authority to fix the compensation
of directors.

     3.12 APPROVAL OF LOANS TO OFFICERS

     The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing in this section contained shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation
at common law or under any statute.

     3.13 REMOVAL OF DIRECTORS

     Unless otherwise restricted by statute, by the certificate of
incorporation or by these bylaws, any director or the entire board of directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that, so long as shareholders of the corporation are entitled to cumulative
voting, if less than the entire board is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire board of
directors.

     No reduction of the authorized number of directors shall have the effect
of removing any director prior to the expiration of such director's term of
office.

     4.1  COMMITTEES OF DIRECTORS

     The board of directors may, by resolution passed by a majority of the whole
board, designate one or more committees, with each committee to consist of one
or more of the directors of the corporation. The board may designate one or more
directors as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the board of
directors to act at the meeting in the place of any such absent or disqualified
member. Any such committee, to the extent provided in the resolution of the
board of directors or in the bylaws of the corporation, shall have and may
exercise all the powers and authority of the board of directors in the
management of the business and affairs of the corporation, and may authorize the
seal of the corporation to be affixed to all papers that may require it; but no
such committee shall have the power or authority to (i) amend the certificate of
incorporation (except that a committee may, to the extent authorized in the
resolution or resolutions providing for the issuance of shares of stock adopted
by the board of directors as provided in Section 151(a) of the General
Corporation Law of Delaware, fix the designations and any of the preferences or
rights of such shares relating to dividends, redemption, dissolution, any
distribution of assets of the corporation or the conversion into, or the
exchange of such shares for, shares of any other class or classes or any other
series of the same or any other class or classes of stock of the corporation or
fix the number of shares of any series of stock or authorize the increase or
decrease of the shares of any series), (ii) adopt an agreement of merger or
consolidation under Sections 251 or 252 of the General Corporation Law of
Delaware, (iii) recommend to the stockholders the sale, lease or exchange of all
or substantially all of the corporation's property and assets, (iv) recommend to
the stockholders a dissolution of the corporation or a revocation of a
dissolution, or (v) amend the bylaws of the corporation; and, unless the board
resolution establishing the committee, the bylaws or the certificate of
incorporation expressly so provide, no such committee shall have the power or
authority to declare a dividend, to authorize the issuance of stock, or to adopt
a certificate of ownership and merger pursuant to Section 253 of the General
Corporation Law of Delaware.

determined either by resolution of the board of directors or by resolution of
the committee, that special meetings of committees may also be called by
resolution of the board of directors and that notice of special meetings of
committees shall also be given to all alternate members, who shall have the
right to attend all meetings of the committee. The board of directors may adopt
rules for the government of any committee not inconsistent with the provisions
of these bylaws.

                                   INDEMNITY

     6.1  THIRD PARTY ACTIONS

     The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement (if such settlement is
approved in advance by the corporation, which approval shall not be
unreasonably withheld) actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create
a presumption that the person did not act in good faith and in a manner which
he reasonably believed to be in or not opposed to the best interest of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     6.2  ACTIONS BY OR IN THE RIGHT OF THE CORPORATION

     The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor
by reason of the fact that he is or was a director, officer, employee or agent
of corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
and amounts paid in settlement (if such settlement is approved in advance by
the corporation, which approval shall not be unreasonably withheld) actually
and reasonably incurred by him in connection with the defense or settlement of
such action or suit if he acted in good faith and in manner he reasonably
believed to be in or not opposed to the best interests of the corporation,
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Delaware Court of Chancery
or the court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper. Notwithstanding any other provision of this Article
VI, no person shall be indemnified hereunder for any expenses or amounts paid
in settlement with respect to any action to recover short-swing profits under
Section 16(b) of the Securities Exchange Act of 1934, as amended.

     6.3 SUCCESSFUL DEFENSE

     To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Sections 6.1 and 6.2, or in defense of
any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

     6.4 DETERMINATION OF CONDUCT

     Any indemnification under Sections 6.1 and 6.2 (unless ordered by a court)
shall be made by the corporation only as authorized in the specific case upon a
determination that the indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in Sections 6.1 and 6.2. Such determination shall be made
(1) by the Board of Directors or the Executive Committee by a majority vote of
a quorum consisting of directors who were not


                                      -17-
<PAGE>   22
parties to such action, suit or proceeding or (2) or if such quorum is not
obtainable or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders. Notwithstanding the foregoing, a director, officer, employee or
agent of the Corporation shall be entitled to contest any determination that
the director, officer, employee or agent has not met the applicable standard of
conduct set forth in Sections 6.1 and 6.2 by petitioning a court of competent
jurisdiction.

     6.5  PAYMENT OF EXPENSES IN ADVANCE

     Expenses incurred in defending a civil or criminal action, suit or
proceeding, by an individual who may be entitled to indemnification pursuant to
Section 6.1 or 6.2, shall be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the director, officer, employee or agent to repay such amount
if it shall ultimately be determined that he is not entitled to be indemnified
by the corporation as authorized in this Article VI.

     6.6  INDEMNITY NOT EXCLUSIVE

     The indemnification and advancement of expenses provided by or granted

disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.

     6.7  INSURANCE INDEMNIFICATION

venture, trust or other enterprise, against any liability asserted against him

<PAGE>   23
indemnify its directors, officers, and employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under and subject to the provisions of this Article VI (including,

                              RECORDS AND REPORTS

     7.1  MAINTENANCE AND INSPECTION OF RECORDS

     The corporation shall, either at its principal executive officer or at
such place or places as designated by the board of directors, keep a record of
its stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these bylaws as amended to date,

                                      -19-
<PAGE>   24
     Any stockholder of record, in person or by attorney or other agent, shall,
upon written demand under oath stating the purpose thereof, have the right
during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In every
instance where any attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney
or such other writing that authorizes the attorney or other agent so to act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

     The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders,
a complete list of the stockholders entitled to vote at the meeting, arranged
in alphabetical order, showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

     7.2  INSPECTION BY DIRECTORS

     Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his position as a director. The Court of Chancery
is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought. The Court may summarily order
the corporation to permit the director to inspect any and all books and
records, the stock ledger, and the stock list and to make copies or extracts
therefrom. The Court may, in its discretion, prescribe any limitations or
conditions with reference to the inspection, or award such other and further
relief as the Court may deem just and proper.

     7.3  ANNUAL STATEMENT TO STOCKHOLDERS

     The board of directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by



                                      -20-

vote of the stockholders, a full and clear statement of the business and
condition of the corporation.

        8.1     CHECKS

        From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders
for payment of money, notes or other evidences of indebtedness that are issued
in the name of or payable to the corporation, and only the persons so
authorized shall sign or endorse those instruments.

        8.2     EXECUTION OF CORPORATION CONTRACTS AND INSTRUMENTS

        The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge
its credit or to render it liable for any purpose or for any amount.

        8.3     STOCK CERTIFICATES; PARTLY PAID SHARES

        The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the corporation. Notwithstanding the adoption of such a resolution by the board
of directors, every holder of stock represented by certificates and upon
request every holder of uncertificated shares shall be entitled to have a
certificate signed by, or in the name of the corporation by the chairman or
vice-chairman of the board of directors, or the president or vice-president,
and by the chief financial officer or an assistant treasurer, or the secretary
or an assistant secretary of such corporation representing the number of shares
registered in certificate form. Any or all of the signatures on the certificate
may be a facsimile. In case any officer, transfer agent or registrar who has
signed or whose facsimile signature has been placed upon a certificate has
ceased to be such officer, transfer agent or registrar before such certificate
is


                                      -21-
<PAGE>   26
issued, it may be issued by the corporation with the same effect as if he were
such officer, transfer agent or registrar at the date of issue.

     The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation
shall declare a dividend upon partly paid shares of the same class, but only
upon the basis of the percentage of the consideration actually paid thereon.

     8.4  SPECIAL DESIGNATION ON CERTIFICATES

     If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the
designations, the preferences, and the relative, participating, optional or
other special rights of each class of stock or series thereof and the
qualifications, limitations or restrictions of such preferences and/or rights.

     8.5  LOST CERTIFICATES

     Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it
on account of the alleged loss, theft or destruction of any such certificate or
the issuance of such new certificate or uncertificated shares.

incorporation, may declare and pay dividends upon the shares of its capital
stock. Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

     The directors of the corporation may set apart out of any of the funds of
the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

board of directors and may be changed by the board of directors.

     Upon surrender to the corporation or the transfer agent of the corporation
of a certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignation or authority to transfer, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate, and record the transaction in its books.

     8.11 STOCK TRANSFER AGREEMENTS

     The corporation shall have power to enter into and perform any agreement
with any number of stockholders of any one or more classes of stock of the
corporation to restrict the transfer of shares of stock of the corporation of
any one or more classes owned by such stockholders in any manner not prohibited
by the General Corporation Law of Delaware.

     8.12 REGISTERED STOCKHOLDERS

     The corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of another person, whether or not it shall
have express or other notice thereof, except as otherwise provided by the laws
of Delaware.

                                   ARTICLE 9

                                   AMENDMENTS

     The bylaws of the corporation may be adopted, amended or repealed by the
stockholders entitled to vote; provided, however, that the corporation may, in
its certificate of incorporation, confer the power to adopt, amend or repeal
bylaws upon the directors. The fact that such power has been so conferred upon
the directors shall not divest the stockholders of the power, nor limit their
power to adopt, amend or repeal bylaws.

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS
AMENDED, OR ANY STATE SECURITIES LAWS. THEY MAY NOT BE SOLD, OFFERED FOR SALE,
PLEDGED, OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT

                               WARRANT AGREEMENT

             To Purchase Shares of the Series C Preferred Stock of

                          ARGONAUT TECHNOLOGIES, INC.

                Dated as of July 7, 1997 (the "Effective Date")

      WHEREAS, Argonaut Technologies, Inc., a Delaware corporation (the
"Company") has entered into a Master Lease Agreement dated as of July 7, 1997,
and Equipment Schedule No. VL-1 dated as of July 7, 1997 and related Summary
Equipment Schedules (collectively, the "Leases") with Comdisco, Inc., a
Delaware corporation (the "Warrantholder"); and

      WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Leases, the right to purchase shares of its Series C Preferred Stock:

      NOW THEREFORE, in consideration of the Warrantholder executing and
delivering such Leases and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder agree as follows:

1.    GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

      The Company hereby grants to the Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth,
to subscribe for and purchase, from the Company, 6,802 fully paid and
non-assessable shares of the Company's Series C Preferred Stock ("Preferred
Stock") at a purchase price of $6.00 per share (the "Exercise Price"). The
number and purchase price of such shares are subject to adjustment as provided
in Section 8 hereof.

2.    TERM OF THE WARRANT AGREEMENT.

      Except as otherwise provided for herein, the term of this Warrant
Agreement and the right to purchase Preferred Stock as granted herein shall
commence on the Effective Date and shall be exercisable for a period of (i)
seven (7) years or (ii) three (3) years from the effective date of the
Company's initial public offering ("IPO"), whichever is longer.

      Notwithstanding the foregoing, upon receipt by Warrantholder of a written
request by the Company's underwriters, the Warrantholder shall exercise its
rights to purchase Preferred Stock hereunder as of the effective date of the
IPO so long as the purchase price per share is equal to or greater than the
Exercise Price. The foregoing exercise at IPO is contingent upon the
underwriter's notice being received by Warrantholder a minimum of ten (10)
business days prior to the effective date of the IPO and if the underwriters
fail to deliver such notice within the aforementioned time period, then
notwithstanding anything to the contrary in this Warrant Agreement, the rights
to purchase the Company's Preferred Stock shall not expire until the
underwriters comply with such notice provisions. Such notice shall also contain
such details of the IPO as are reasonable in the circumstances. If the IPO does
not take place, the Company shall promptly notify the Warrantholder and the
Warrantholder may rescind any exercise of its purchase rights promptly after
such notice. In the event of such rescission, the Warrant Agreement will
continue to be exercisable on the same terms and conditions contained herein.

<PAGE>   2
3.    EXERCISE OF THE PURCHASE RIGHTS.

      The purchase rights set forth in this Warrant Agreement are exercisable
by the Warrantholder, in whole or in part, at any time, or from time to time,
prior to the expiration of the term set forth in Section 2 above, by tendering
to the Company at its principal office a notice of exercise in the form
attached hereto as Exhibit 1 (the "Notice of Exercise"), duly completed and
executed, along with this Warrant Agreement. Promptly upon receipt of the
Notice of Exercise, this Warrant Agreement and the payment of the purchase
price in accordance with the terms set forth below, the Company shall issue to
the Warrantholder a certificate for the number of shares of Preferred Stock
purchased.

      The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of the right to purchase such number of
shares equal in value (as determined below) to the aggregate exercise price of
the number of shares to be purchased by the Warrantholder ("Net Issuance"). If
the Warrantholder elects the Net Issuance method, the Company will issue
Preferred Stock in accordance with the following formula:

                  X = Y(A-B)
                      ------
                        A

      Where: X =  the number of shares of Preferred Stock to be issued to the
                  Warrantholder.

                  Y =   the number of shares of Preferred Stock requested to be
                        exercised under this Warrant Agreement.

                  A =   the fair market value of one (1) share of Preferred
                        Stock.

                  B =   the Exercise Price.

      For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

            (i)   if the exercise is in connection with an initial public
      offering of the Company's Common Stock, and if the Company's Registration
      Statement relating to such public offering has been declared effective by
      the SEC, then the fair market value per share shall be the product of (x)
      the initial "Price to Public" specified in the final prospectus with
      respect to the offering and (y) the number of shares of Common Stock into
      which each share of Preferred Stock is convertible at the time of such
      exercise;

            (ii)  if this Warrant is exercised after, and not on connection
      with the Company's initial public offering, and:

                  (a)   if the Company's Common Stock is traded on a securities
            exchange, the fair market value shall be deemed to be the product
            of (x) the average of the closing prices over a twenty-one (21) day
            period ending three days before the day the current fair market
            value of the securities is being determined and (y) the number of
            shares of Common Stock into which each share of Preferred Stock is
            convertible at the time of such exercise; or

                  (b)   if the Company's Common Stock is actively traded
            over-the-counter, the fair market value shall be deemed to be the
            product of (x) the average of the closing bid and asked prices
            quoted on the Nasdaq National Market System (or similar system)
            over the twenty-one (21) day period ending three days before the
            day the current fair market value of the securities is being
            determined and (y) the number of shares of Common Stock into which
            each share of Preferred Stock is convertible at the time of such
            exercise;

            (iii) if at any time the Common Stock is not listed on any
      securities exchange or quoted in the Nasdaq National Market System or the
      over-the-counter market, the current fair market value of Preferred Stock
      shall be the product of (x) the highest price per share which the Company
      could obtain from a willing buyer (not a current employee or director)
      for shares of Common Stock sold by the Company, from authorized but
      unissued shares, as determined in good faith by its Board of Directors
      and (y) the number of shares of Common Stock into which each share of
      Preferred Stock is convertible at the time of such


Warrant Lease                         -2-
<PAGE>   3
      exercise, unless the exercise is in connection with a merger, acquisition
      or other consolidation of the Company pursuant to which the Company is
      not the surviving party, in which case the fair market value of Preferred
      Stock shall be deemed to be the value received by the holders of the
      Company's Preferred Stock on a common equivalent basis pursuant to such
      merger or acquisition.

      Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number
of shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.    RESERVATION OF SHARES.

      (a)   Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

      (b)   Registration of Listing. If any shares of Preferred Stock required
to be reserved for purposes of the exercise of this Warrant Agreement hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal
statute then enforced, or any state securities law, required by reason of any
transfer involved in such conversion), or listing on any domestic securities
exchange, before such shares may be issued upon conversion, the Company will,
at its expense and as expeditiously as possible, use its best efforts to cause
such shares to be duly registered, listed or approved for listing on such
domestic securities exchange, as the case may be.

5.    NO FRACTIONAL SHARES OR SCRIP.

      No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrantholder's rights to purchase Preferred
Stock, but in lieu of such fractional shares the Company shall make a cash
payment therefor upon the basis of the Exercise Price then in effect.

6.    NO RIGHTS AS SHAREHOLDER.

      This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrantholder's rights to purchase Preferred Stock as provided for herein.

7.    WARRANTHOLDER REGISTRY.

      The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.    ADJUSTMENT RIGHTS.

      The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

      (a)   Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of its rights to purchase
Preferred Stock, the number of shares of Preferred Stock or other securities of
the successor corporation resulting from such Merger Event, to which a holder of
the Preferred Stock deliverable upon exercise of the right to purchase Preferred
Stock hereunder would have been entitled in such Merger Event if the right to
purchase such Preferred Stock hereunder had been exercised immediately prior to
the Merger Event. In any such case, appropriate adjustment (as determined in
good faith by the Company's Board of Directors) shall be made in the application
of the provisions of this Warrant Agreement with respect to the rights and
interest of the Warrantholder after the Merger Event to the end that the
provisions of this Warrant Agreement (including adjustments of the

Warrant Lease                         -3-
<PAGE>   4
Exercise Price and number of shares of Preferred Stock purchasable) shall be
applicable to the greatest extent reasonably possible.

      (b)   Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of
any other class or classes, this Warrant Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been
issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Warrant Agreement immediately prior
to such combination, reclassification, exchange, subdivision or other change.

      (c)   Subdivision or Combination of Shares. If the Company at any time
shall combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision or proportionately
increased in the case of a combination.

      (d)   Right to Purchase Additional Stock. If, the Warrantholder's total
cost of equipment leased pursuant to the Leases exceeds $1,100,000.00,
Warrantholder shall have the right to purchase from the Company, at the
Exercise Price (adjusted as set forth herein), an additional number of shares,
which number shall be determined by (i) multiplying the amount by which the
Warrantholder's total equipment cost exceeds $1,100,000.00 by 4%, and (ii)
dividing the product thereof by the Exercise Price per share referenced above.

      (e)   Antidilution Rights. The Preferred Stock purchasable hereunder
shall have the benefit of the same antidilution rights applicable to such
Preferred Stock as designated in the Company's Certificate of Incorporation, as
such may be amended from time to time, and the Company shall provide
Warrantholder with all notices and information at the times and to the extent
it is required to do so to the holders of such Preferred Stock.

      (f)   Notice of Adjustments. If: (i) the Company shall declare any
dividend or distribution upon its stock, whether in cash, property, stock or
other securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any Merger
Event; (iv) there shall be any voluntary dissolution, liquidation or winding up
of the Company; then, in connection with each such event, the Company shall
send to the Warrantholder: (A) at least twenty (20) days' prior written notice
of the date on which the books of the Company shall close or a record shall be
taken for such dividend, distribution, subscription rights (specifying the date
on which the holders of Preferred Stock shall be entitled thereto) or for
determining rights to vote in respect of such Merger Event, dissolution
liquidation or winding up; and (B) in the case of any such Merger Event,
dissolution, liquidation or winding up, at least twenty (20) days' prior
written notice of the date when the same shall take place (and specifying the
date on which the holders of Preferred Stock shall be entitled to exchange
their Preferred Stock for securities or other property deliverable upon such
Merger Event, dissolution, liquidation or winding up).

      Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and
(v) the number of shares subject to the purchase hereunder after giving effect
to such adjustment, and shall be given by first class mail, postage prepaid,
addressed to the Warrantholder, at the address as shown on the books of the
Company.

      (g)   Timely Notice. Failure to timely provide such notice required by
subsection (f) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.

3.    REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

      (a)   Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will
be validly issued, fully paid and non-assessable, and will be free of any
taxes, liens, charges or encumbrances of any nature whatsoever, provided,
however, that the Preferred Stock issuable pursuant to this Warrant Agreement
may be subject to restrictions on transfer under state and/or Federal
securities laws. The Company has made available to the Warrantholder true,
correct and complete copies of its Certificate of Incorporation (the "Charter")
and Bylaws, as amended. The issuance of certificates for shares of Preferred
Stock upon exercise of the Warrant Agreement shall be made without charge to
the Warrantholder for any issuance tax in respect thereof, or other cost
incurred by the Company in connection with such exercise and the related
issuance of


Warrant Lease                         -4-
<PAGE>   5
shares of Preferred Stock; provided that the Company shall not be required to
pay any tax which may be payable in respect of any transfer involved and the
issuance and delivery of any certificate in a name other than that of the
Warrantholder.

      (b)   Due Authority. The execution and delivery by the Company of this
Warrant Agreement and the performance of all obligations of the Company
hereunder, including the issuance to Warrantholder of the right to acquire the
shares of Preferred Stock set forth in Section 1, have been duly authorized by
all necessary corporate action on the part of the Company, and the Leases and
this Warrant Agreement are not inconsistent with the Company's Charter or
Bylaws, do not contravene any law or governmental rule, regulation or order
applicable to it, do not and will not contravene any provision of, or
constitute a default under any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound, and the Leases and
this Warrant Agreement constitute legal, valid and binding agreements of the
Company, enforceable in accordance with their respective terms subject only to
bankruptcy, insolvency or other similar laws affecting the enforceability to
the rights of creditors generally and the general principles of equity.

      (c)   Consents and Approvals. No consent or approval of, giving of notice
to, registration with, or taking of any other action in respect of any state,
Federal or other governmental authority or agency is required with respect to
the execution, delivery and performance by the Company of its obligations under
this Warrant Agreement, except for the filing of notices pursuant to Regulation
D under the 1933 Act and any filing required by applicable state securities
law, which filings will be effective by the time required thereby.

      (d)   Issued Securities. All issued and outstanding shares of Common
Stock, Preferred Stock or any other securities of the Company have been duly
authorized and validly issued and are fully paid and nonassessable. All
outstanding shares of Common Stock, Preferred Stock, and any other securities
were issued in full compliance with all Federal and state securities laws. In
addition:

            (i)   The authorized capital stock of the Company consists of

      stock, of which 5,000,000 are designated as Series A Preferred Stock,
      5,000,000 shares are designated Series A-1 Preferred Stock, 3,000,000
      shares are designated Series B Preferred Stock, 3,000,000 shares are
      designated Series B-1 Preferred Stock, 1,600,000 shares are designated
      Series C Preferred Stock, and 1,600,000 shares are designated Series C-1
      Preferred Stock. The issued and outstanding stock of the Company consists
      1,903,708 shares of Common Stock, 4,627,500 shares of Series A Preferred
      Stock, no shares of Series A-1 Preferred Stock, 2,923,073 shares of Series
      B Preferred Stock, no shares of Series B-1 Preferred Stock, 1,180,000

      have the rights, preferences, privileges and restrictions set forth in the
      Charter.

      (ii)  The Company has reserved 1,685,308 shares of its Common Stock for
      issuance to officers, directors, employees, sales representatives and
      consultants of the Company pursuant to the Company's 1995 Incentive Stock
      Plan. There are stock options outstanding for the purchase of 1,215,575
      shares of Common Stock. There are also warrants outstanding for the
      purchase of 55,000 shares of Common Stock. Except as referenced herein,
      there are no options, warrants, conversion privileges or other rights
      presently outstanding to purchase or otherwise acquire any authorized but
      unissued shares of the capital stock or other securities of the Company.

      (e)   Insurance. The Company has in full force and effect insurance
policies, with extended coverage, insuring the Company and its property and
business against such losses and risks, and in such amounts, as are customary
for corporations engaged in a similar business and similarly situated and as
otherwise may be required pursuant to the terms of any other contract or
agreement.

      (f)   Exempt Transaction. Subject to the accuracy of the Warrantholder's
representations in Section 10 hereof, the issuance of the Preferred Stock upon
exercise of the Warrantholder's right to purchase such Preferred Stock will
constitute a transaction exempt from (i) the registration requirements of
Section 5 of the 1933 Act, in reliance upon Section 4(2) thereof, and (ii) the
qualification requirements of the applicable state securities laws.

      (g)   Compliance with Rule 144. At the written request of the
Warrantholder, who proposes to sell Preferred Stock issuable upon the exercise
of the Warrant in compliance with Rule 144 promulgated by the Securities and
Exchange Commission under the 1933 Act, the Company shall furnish to the
Warrantholder, within

Warrant Lease                         -5-
<PAGE>   6
ten days after receipt of such request, a written statement confirming the
Company's compliance with the filing requirements of the Securities and
Exchange Commission as set forth in such Rule as then applicable to the
Company, as such Rule may be amended from time to time.

10.   REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

      This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder which by
its execution hereof the Warrantholder hereby confirms:

      (a)   Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present
intention of selling or engaging in any public distribution of the same except
pursuant to a registration or exemption.

      (b)   Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

      (c)   Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an option of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required. Whenever the
restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

      (d)   Financial Risk. The Warrantholder has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

      (e)   Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act, or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period. The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

      (f)   Accredited Investor. Warrantholder is an "accredited investor"
within the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

Warrant Lease                         -6-

11.   LOCKUP AGREEMENT.

      Warrantholder agrees that, if, in connection with the Company's IPO of
the Company's securities, the Company or the underwriters managing the offering
so request, the Warrantholder shall not sell, make any short sale of, loan,
grant any option for the purchase of, or otherwise dispose of any right to
purchase Preferred Stock hereunder or any Preferred Stock issuable upon
exercise of its rights hereunder without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed one hundred eighty (180) days) from the effective date of the IPO as
may be requested by the Company or the underwriters; provided that each officer
and director of the Company who own stock of the Company also agrees to such
restrictions. This Section 11 shall be binding on all transferees or assignees
of Warrantholder.

12.   TRANSFERS.

      Subject to the terms and conditions contained in Section 10 hereof, this
Warrant Agreement and all rights hereunder are transferable in whole or in part
by the Warrantholder and any successor transferee, provided, however, in no
event shall the number of transfers of the rights and interests in all of the
Warrants exceed three (3) transfers. The transfer shall be recorded on the
books of the Company upon receipt by the Company of a notice of transfer in the
form attached hereto as Exhibit III (the "Transfer Notice"), at its principal
offices and the payment to the Company of all transfer taxes and other
governmental charges imposed on such transfer.

      (f)   Remedies. In the event of any default hereunder, the non-defaulting
party may proceed to protect and enforce its rights either by suit in equity
and/or by action at law, including but not limited to an action for damages as
a result of any such default, and/or an action for specific performance for any
default where Warrantholder will not have an adequate remedy at law and where
damages will not be readily ascertainable. The Company expressly agrees that it
shall not oppose an application by the Warrantholder or any other person
entitled to the benefit of this Agreement requiring specific performance of any
or all provisions hereof or enjoining the Company from continuing to commit any
such breach of this Agreement.

      (g)   No Impairment of Rights. The Company will not, by amendment of its

faith assist in the carrying out of all such terms and in the taking of all

                               WARRANT AGREEMENT

             To Purchase Shares of the Series C Preferred Stock of

                          ARGONAUT TECHNOLOGIES, INC.

               Dated as of August 12, 1997 (the "Effective Date")

        in connection with the Subordinated Loan and Security Agreement

     WHEREAS, Argonaut Technologies, Inc., a Delaware corporation (the
"Company") has entered into a Subordinated Loan and Security Agreement dated as
of July 7, 1997, and a Subordinated Promissory Note (collectively, the
"Subordinated Loan") with Comdisco, Inc., a Delaware corporation (the
"Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Subordinated Loan, the right to purchase shares of its Series C
Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Subordinated Loan and in consideration of mutual covenants and
agreements contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe for and purchase, from the Company, 25,000 fully paid and
non-assessable shares of the Company's Series C Preferred Stock ("Preferred
Stock") at a purchase price of $6.00 per share (the "Exercise Price").

     Notwithstanding the foregoing, in the event the Company has repaid the
Subordinated Loan on or prior to the twelfth (12th) month such is outstanding,
the number of shares which Warrantholder is entitled to subscribe for and
purchase hereunder shall be reduced to 15,000 shares of Preferred Stock at the
Exercise Price. Further, in the event the Company has repaid the Subordinated
Loan on or prior to the twenty-fourth (24th) month such is outstanding, the
number of shares which Warrantholder is entitled to subscribe for and purchase
hereunder shall be reduced to 20,000 shares of Preferred Stock at the Exercise
Price.

     The number and purchase price of such shares are subject to adjustment as
provided in Section B hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
or (ii) three (3) years from the effective date of the Company's initial public
offering ("IPO"), whichever is longer.

     Notwithstanding the foregoing, upon receipt by Warrantholder of a written
request by the Company's underwriters, the Warrantholder shall exercise its
rights to purchase Preferred Stock hereunder as of the effective date of the
IPO so long as the purchase price per share is equal to or greater than the
Exercise Price. The foregoing exercise at IPO is contingent upon the
underwriter's notice being received by Warrantholder a minimum of ten (10)
business days prior to the effective date of the IPO and if the underwriters
fail to deliver such notice within the aforementioned time period, then
notwithstanding anything to the contrary in this Warrant Agreement, the rights
to purchase the Company's Preferred Stock shall not expire until the
underwriters comply with such notice provisions.



                                      -1-
<PAGE>   2
Such notice shall also contain such details of the IPO as are reasonable in the
circumstances. If the IPO does not take place, the Company shall promptly
notify the Warrantholder and the Warrantholder may rescind any exercise of its
purchase rights promptly after such notice. In the event of such rescission,
the Warrant Agreement will continue to be exercisable on the same terms and
conditions contained herein.

3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time prior
to the expiration of the term set forth in Section 2 above, by tendering to the
Company at its principal office a notice of exercise in the form attached
hereto as Exhibit 1 (the "Notice of Exercise"), duly completed and executed,
along with this Warrant Agreement. Promptly upon receipt of the Notice of
Exercise, this Warrant Agreement and the payment of the purchase price in
accordance with the terms set forth below, the Company shall issue to the
Warrantholder a certificate for the number of shares of Preferred Stock
purchased.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, (ii) forgiveness of the indebtedness under the Subordinated
Loan, or (iii) by surrender of the right to purchase such number of shares
equal in value (as determined below) to the aggregate exercise price of the
number of shares to be purchased by the Warrantholder ("Net Issuance"). If the
Warrantholder elects the Net Issuance method, the Company will issue Preferred
Stock in accordance with the following formula:

          X = Y(A-B)
             -------
                A

Where: X = the number of shares of Preferred Stock to be issued to the
           Warrantholder.

               Y = the number of shares of Preferred Stock requested to be
                   exercised under this Warrant Agreement.

               A = the fair market value of one (1) share of Preferred Stock.

               B = the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each shares of Preferred Stock:

     (i)  If the exercise is in connection with an initial public offering of
the Company's Common Stock, and if the Company's Registration Statement
relating to such public offering has been declared effective by the SEC, then
the fair market value per share shall be the product of (x) the initial "Price
to Public" specified in the final prospectus with respect to the offering and
(y) the number of shares of Common Stock into which each share of Preferred
Stock is convertible at the time of such exercise;

     (ii) If this Warrant is exercised after, and not in connection with the
Company's initial public offering, and;

          (a)  If the Company's Common Stock is traded on a securities
exchange, the fair market value shall be deemed to be the product of (x) the
average of the closing prices over a twenty-one (21) day period ending three
days before the day the current fair market value of the securities is being
determined and (y) the number of shares of Common Stock into which each share
of Preferred Stock is convertible at the time of such exercise; or

          (b)  If the Company's Common Stock is actively traded
over-the-counter, the fair market value shall be deemed to be the product of
(x) the average of the closing bid and asked prices quoted on the Nasdaq
National Market system (or similar system) over the twenty-one (21) day period
ending three days before the day the current fair market value of the
securities is being determined and (y) the number of shares of Common Stock
into which each share of Preferred Stock is convertible at the time of such
exercise;


     (iii) If at any time the Common Stock is not listed on any securities
exchange or quoted in the Nasdaq National Market System or the over-the-counter
market, the current fair market value of Preferred



                                      -2-
<PAGE>   3
      Stock shall be the product of (x) the highest price per share which the
      Company could obtain from a willing buyer (not a current employee or
      director) for shares of Common Stock sold by the Company, from authorized
      but unissued shares, as determined in good faith by its Board of
      Directors and (y) the number of shares of Common Stock into which each
      share of Preferred Stock is convertible at the time of such exercise,
      unless the exercise is in connection with a merger, acquisition or other
      consolidation of the Company pursuant to which the Company is not the
      surviving party, in which case the fair market value of Preferred Stock
      shall be deemed to be the value received by the holders of the Company's
      Preferred Stock on a common equivalent basis pursuant to such merger or
      acquisition.

      Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number
of shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.    RESERVATION OF SHARES.

      (a)   Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

      (b)   Registration or Listing. If any shares of Preferred Stock required
to be reserved for purposes of the exercise of this Warrant Agreement hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal
statute then enforced, or any state securities law, required by reason of any
transfer involved in such conversion), or listing on any domestic securities
exchange, before such shares may be issued upon conversion, the Company will,
at its expense and as expeditiously as possible, use its best efforts to cause
such shares to be duly registered, listed or approved for listing on such
domestic securities exchange, as the case may be.

5.    NO FRACTIONAL SHARES OR SCRIP.

      No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrantholder's rights to purchase Preferred
Stock, but in lieu of such fractional shares the Company shall make a cash
payment therefor upon the basis of the Exercise Price then in effect.

6.    NO RIGHTS AS SHAREHOLDER.

      This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrantholder's rights to purchase Preferred Stock as provided for herein.

7.    WARRANTHOLDER REGISTRY.

      The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.    ADJUSTMENT RIGHTS.

      The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

      (a)   Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger of consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of its rights to purchase
Preferred Stock, the number of shares of Preferred Stock or other securities of
the successor corporation resulting from such Merger Event, to which a holder
of the Preferred Stock deliverable upon exercise of the right to purchase
Preferred Stock hereunder would have been entitled in such Merger Event if the
right to purchase such


                                      -3-
<PAGE>   4
Preferred Stock hereunder had been exercised immediately prior to the Merger
Event. In any such case, appropriate adjustment (as determined in good faith by
the Company's Board of Directors) shall be made in the application of the
provisions of this Warrant Agreement with respect to the rights and interest of
the Warrantholder after the Merger Event to the end that the provisions of this
Warrant Agreement (including adjustments of the Exercise Price and number of
shares of Preferred Stock purchasable) shall be applicable to the greatest
extent reasonably possible.

     (b)  Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of
any other class or classes, this Warrant Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been
issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Warrant Agreement immediately prior
to such combination, reclassification, exchange, subdivision or other change.

     (c)  Subdivision or Combination of Shares. If the Company at any time
shall combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d)  Antidilution Rights. The Preferred Stock purchasable hereunder shall
have the benefit of the same antidilution rights applicable to such Preferred
Stock as designed in the Company's Certificate of Incorporation, as such may be
amended from time to time, and the Company shall provide Warrantholder with all
notices and information at the times and to the extent it is required to do so
to the holders of such Preferred Stock.

     (e)  Notice of Adjustments. If: (i) the Company shall declare any dividend
or distribution upon its stock, whether in cash, property, stock or other
securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any Merger
Event: (iv) there shall be any voluntary dissolution, liquidation or winding up
of the Company; then, in connection with each such event, the Company shall
send to the Warrantholder: (A) at least twenty (20) days' prior written notice
of the date on which the books of the Company shall close or a record shall be
taken for such dividend, distribution, subscription rights (specifying the date
on which the holders of Preferred Stock shall be entitled thereto) or for
determining rights to vote in respect of such Merger Event, dissolution,
liquidation or winding up: and (B) in the case of any such Merger Event,
dissolution, liquidation or winding up, at least twenty (20) days' prior written
notice of the date when the same shall take place (and specifying the date on
which the holders of Preferred Stock shall be entitled to exchange their
Preferred Stock for securities or other property deliverable upon such Merger
Event, dissolution, liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and
(v) the number of shares subject to purchase hereunder after giving effect to
such adjustment, and shall be given by first class mail, postage prepaid,
addressed to the Warrantholder, at the address as shown on the books of the
Company.

     (f)  Timely Notice. Failure to timely provide such notice required by
subsection (e) above shall entitled Warrantholder to retail the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.

9.   REPRESENTATIVES, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a)  Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will
be validly issued, fully paid and non-assessable, and will be free of any
taxes, liens, charges or encumbrances of any nature whatsoever; provided,
however, that the Preferred Stock issuable pursuant to this Warrant Agreement

correct and complete copies of its Certificate of Incorporation (the "Charter")

required to pay any tax which may be payable in



                                      -4-
<PAGE>   5
respect of any transfer involved and the issuance and delivery of any
certificate in a name other than that of the Warrantholder.

Warrant Agreement and the performance of all obligations of the Company
hereunder, including the issuance to Warrantholder of the right to acquire the
shares of Preferred Stock set forth in Section 1, have been duly authorized by
all necessary corporate action on the part of the Company, and the Subordinated
Loan and this Warrant Agreement are not inconsistent with the Company's Charter
or Bylaws, do not contravene any law or governmental rule, regulation or order
applicable to it, do not and will not contravene any provision of, or constitute
a default under, any indenture, mortgage, contract or other instrument to which
it is a party or by which it is bound, and the Subordinated Loan and this
Warrant Agreement constitute legal, valid and binding agreements of the Company,

bankruptcy, insolvency or other similar laws affecting the enforceability of the
rights of creditors generally and the general principles of equity.

     (c)  Consents and Approvals. No consent or approval of, giving of notice

otherwise may be required pursuant to the terms of any other contract or
agreement.

     (f)  Exempt Transaction. Subject to the accuracy of the Warrantholder's
representations in Section 10 hereof, the issuance of the Preferred Stock upon
exercise of the Warrantholder's right to purchase such Preferred Stock will
constitute a transaction exempt from (i) the registration requirements of

qualification requirements of the applicable state securities laws.

     (g)  Compliance with Rule 144. At the written request of the Warrantholder,
who proposes to sell Preferred Stock issuable upon the exercise of the Warrant
in compliance with Rule 144 promulgated by the Securities and Exchange
Commission under the 1933 Act, the Company shall furnish to the Warrantholder,
within ten days after receipt of such request, a written statement confirming
the Company's compliance with the filing


                                      -5-
<PAGE>   6
requirements of the Securities and Exchange Commission as set forth in such Rule
as then applicable to the Company, as such Rule may be amended from time to
time.

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder which by
its execution hereof the Warrantholder hereby confirms:

     (a)  Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b)  Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)  Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required. Whenever the
restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d)  Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e)  Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act, or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period. The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f)  Accredited Investor. Warrantholder is an "accredited investor" within
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.


                                      -6-
<PAGE>   7
11.  ADDITIONAL WARRANTS.

     In the event the Company has not repaid the Subordinated Loan in its
entirety by the maturity date as set forth in the Subordinated Promissory Note,
Warrantholder shall have the right to purchase from the Company, at the
Exercise Price (adjusted as set forth herein) an additional number of shares of
Preferred Stock determined by (i) multiplying the outstanding principal amount
of the Subordinated Loan by one percent (1%) for each month such amount is
outstanding, and (ii) dividing the product thereof by the Exercise Price per
share.

12.  LOCKUP AGREEMENT.

     Warrantholder agrees that, if, in connection with the Company's IPO of the
Company's securities, the Company of the underwriters managing the offering so
request, the Warrantholder shall not sell, make any short sale of, loan, grant
any option for the purchase of, or otherwise dispose of any right to purchase
Preferred Stock hereunder or any Preferred Stock issuable upon exercise of its
rights hereunder without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed one
hundred eighty (180) days) from the effective date of the IPO as may be
requested by the Company or the underwriters; provided that each officer and
director of the Company who own stock of the Company also agrees to such
restrictions. This Section 11 shall be binding on all transferees or assignees
of Warrantholder.

13.  TRANSFERS.

     Subject to the terms and conditions contained in Section 10 hereof, this
Warrant Agreement and all rights hereunder are transferable in whole or in part
by the Warrantholder and any successor transferee, provided, however, in no
event shall the number of transfers of the rights and interests in all of the
Warrants exceed three (3) transfers. The transfer shall be recorded on the books
of the Company upon receipt by the Company of a notice of transfer in the form
attached hereto as Exhibit III (the "Transfer Notice"), at its principal

AMENDED, OR ANY STATE SECURITIES LAWS. THEY MAY NOT BE SOLD, OFFERED FOR SALE,
PLEDGED, OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT

REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED

SECURITIES LAWS.


                               WARRANT AGREEMENT

             To Purchase Shares of the Series C Preferred Stock of

                          ARGONAUT TECHNOLOGIES, INC.

               Dated as of August 12, 1997 (the "Effective Date")

               in connection with the Loan and Security Agreement

     WHEREAS, Argonaut Technologies, Inc., a Delaware corporation (the
"Company") has entered into a Loan and Security Agreement dated as of July 7,
1997, and a Secured Promissory Note (collectively, the "Loan") with Comdisco,
Inc., a Delaware corporation (the "Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Loans, the right to purchase shares of its Series C Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Loans and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to the Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe for and purchase, from the Company, 3,197 fully paid and
non-assessable shares of the Company's Series C Preferred Stock ("Preferred
Stock") at a purchase price of $6.00 per share (the "Exercise Price"). The
number and purchase price of such shares are subject to adjustment as provided
in Section 8 hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
or (ii) three (3) years from the effective date of the Company's initial public
offering ("IPO"), whichever is longer.

     Notwithstanding the foregoing, upon receipt by Warrantholder of a written
request by the Company's underwriters, the Warrantholder shall exercise its
rights to purchase Preferred Stock hereunder as of the effective date of the
IPO so long as the purchase price per share is equal to or greater than the
Exercise Price. The foregoing exercise at IPO is contingent upon the
underwriter's notice being received by Warrantholder a minimum of ten (10)
business days prior to the effective date of the IPO and if the underwriters
fail to deliver such notice within the aforementioned time period, then
notwithstanding anything to the contrary in this Warrant Agreement, the rights
to purchase the Company's Preferred Stock shall not expire until the
underwriters comply with such notice provisions. Such notice shall also contain
such details of the IPO as are reasonable in the circumstances. If the IPO does
not take place, the Company shall promptly notify the Warrantholder and the
Warrantholder may rescind any exercise of its purchase rights promptly after
such notice. In the event of such rescission, the Warrant Agreement will
continue to be exercisable on the same terms and conditions contained herein.


                                      -1-
<PAGE>   2

3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time,
prior to the expiration of the term set forth in Section 2 above, by tendering
to the Company at its principal office a notice of exercise in the form
attached hereto as Exhibit 1 (the "Notice of Exercise"), duly completed and
executed, along with this Warrant Agreement. Promptly upon receipt of the
Notice of Exercise, this Warrant Agreement and the payment of the purchase
price in accordance with the terms set forth below, the Company shall issue to
the Warrantholder a certificate for the number of shares of Preferred Stock
purchased.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of the right to purchase such number of
shares equal in value (as determined below) to the aggregate exercise price of
the number of shares to be purchased by the Warrantholder ("Net Issuance"). If
the Warrantholder elects the Net issuance method, the Company will issue
Preferred Stock in accordance with the following formula:

         X  =  Y(A-B)
              -------
                 A

     Where: X =     the number of shares of Preferred Stock to be issued to
                    the Warrantholder.

                     Y =     the number of shares of Preferred Stock requested
                             to be exercised under this Warrant Agreement.

                     A =     the fair market value of one (1) share of Preferred
                             Stock.

                     B =     the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each shares of Preferred Stock:

     (i)  if the exercise is in connection with an initial public offering of
the Company's Common Stock, and if the Company's Registration Statement relating
to such public offering has been declared effective by the SEC, then the fair
market value per share shall be the product of (x) the initial "Price to Public"
specified in the final prospectus with respect to the offering and (y) the
number of shares of Common Stock into which each share of Preferred Stock is
convertible at the time of such exercise;

     (ii) if this Warrant is exercised after, and not in connection with the
Company's initial public offering, and:

          (a)  if the Company's Common Stock is traded on a securities
exchange, the fair market value shall be deemed to be the product of (x) the
average of the closing prices over a twenty-one (21) day period ending three
days before the day the current fair market value of the securities is being
determined and (y) the number of shares of Common Stock into which each share
of Preferred Stock is convertible at the time of such exercise; or

          (b)  if the Company's Common Stock is actively traded
over-the-counter, the fair market value shall be deemed to be the product of
(x) the average of the closing bid and asked prices quoted on the Nasdaq
National Market system (or similar system) over the twenty-one (21) day period
ending three days before the day the current fair market value of the
securities is being determined and (y) the number of shares of Common Stock
into which each share of Preferred Stock is convertible at the time of such
exercise;

     (iii) if at any time the Common Stock is not listed on any securities
exchange or quoted in the Nasdaq National Market System or the over-the-counter
market, the current fair market value of Preferred Stock shall be the product
of (x) the highest price per share which the Company could obtain from a
willing buyer (not a current employee or director) for shares of Common Stock
sold by the Company, from authorized but unissued shares, as determined in good
faith by its Board of Directors and (y) the number of shares of Common Stock
into which each share of Preferred Stock is convertible at the time of such



                                      -2-


<PAGE>   3

     exercise, unless the exercise is in connection with a merger, acquisition
     or other consolidation of the Company pursuant to which the Company is not
     the surviving party, in which case the fair market value of Preferred
     Stock shall be deemed to be the value received by the holders of the
     Company's Preferred Stock on a common equivalent basis pursuant to such
     merger or acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number
of shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.

     (a)  Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b)  Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of the exercise of this Warrant Agreement hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal
statute then enforced, or any state securities law, required by reason of any
transfer involved in such conversion), or listing on any domestic securities
exchange, before such shares may be issued upon conversion, the Company will,
at its expense and as expeditiously as possible, use its best efforts to cause
such shares to be duly registered, listed or approved for listing on such
domestic securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.

     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrantholder's rights to purchase Preferred
Stock, but in lieu of such fractional shares the Company shall make a cash
payment therefor upon the basis of the Exercise Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrantholder's rights to purchase Preferred Stock as provided for herein.

7.   WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a)  Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of its rights to purchase
Preferred Stock, the number of shares of Preferred Stock or other securities of
the successor corporation resulting from such Merger Event, to which a holder
of the Preferred Stock deliverable upon exercise of the right to purchase
Preferred Stock hereunder would have been entitled in such Merger Event if the
right to purchase such Preferred Stock hereunder had been exercised immediately
prior to the Merger Event. In any such case, appropriate adjustment (as
determined in good faith by the Company's Board of Directors) shall be made in
the application of the provisions of this Warrant Agreement with respect to the
rights and interest of the Warrantholder after the Merger Event to the end that
the provisions of this Warrant Agreement (including adjustments of the


                                      -3-
<PAGE>   4

Exercise Price and number of shares of Preferred Stock purchasable) shall be
applicable to the greatest extent reasonably possible.

     (b)  Reclassification of Shares.  If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of
any other class or classes, this Warrant Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been
issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Warrant Agreement immediately prior
to such combination, reclassification, exchange, subdivision or other change.

     (c)  Subdivision or Combination of Shares.  If the Company at any time
shall combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d)  Antidilution Rights.  The Preferred Stock purchasable hereunder shall
have the benefit of the same antidilution rights applicable to such Preferred
Stock as designated in the Company's Certificate of Incorporation, as such may
be amended from time to time, and the Company shall provide Warrantholder with
all notices and information at the times and to the extent it is required to do
so to the holders of such Preferred Stock.

     (e)  Notice of Adjustments.  If: (i) the Company shall declare any
dividend or distribution upon its stock, whether in cash, property, stock or
other securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock or any class or other rights; (iii) there shall be any Merger
Event; (iv) there shall be any voluntary dissolution, liquidation or winding up
of the Company; then, in connection with each such event, the Company shall
send to the Warrantholder: (A) at least twenty (20) days' prior written notice
of the date on which the books of the Company shall close or a record shall be
taken for such dividend, distribution, subscription rights (specifying the date
on which the holders of Preferred Stock shall be entitled thereto) or for
determining rights to vote in respect of such Merger Event, dissolution,
liquidation or winding up; and (B) in the case of any such Merger Event,
dissolution, liquidation or winding up at least twenty (20) days' prior written
notice of the date when the same shall take place (and specifying the date of
which the holders of Preferred Stock shall be entitled to exchange their
Preferred Stock for securities or other property deliverable upon such Merger
Event, dissolution, liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and
(v) the number of shares subject to purchase hereunder after giving effect to
such adjustment, and shall be given by first class mail, postage prepaid,
addressed to the Warrantholder, at the address as shown on the books of the
Company.

     (f)  Timely Notice.  Failure to timely provide such notice required by
subsection (e) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.

9.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a)  Reservation of Preferred Stock.  The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will
be validly issued, fully paid and non-assessable, and will be free of any
taxes, liens, charges or encumbrances of any nature whatsoever, provided,
however, that the Preferred Stock issuable pursuant to this Warrant may be
subject to restrictions on transfer under state and/or Federal securities laws.
The Company has made available to the Warrantholder true, correct and complete
copies of its Certificate of Incorporation (the "Charter") and Bylaws, as
amended. The issuance of certificates for shares of Preferred Stock upon
exercise of the Warrant Agreement shall be made without charge to the
Warrantholder for any issuance tax in respect thereof, or other cost incurred
by the Company in connection with such exercise and the related issuance of
shares of Preferred Stock; provided that the Company shall not be required to
pay any tax which may be payable in respect of any transfer involved and the
issuance and delivery of any certificate in a name other than that of the
Warrantholder.

     (b)  Due Authority.  The execution and delivery by the Company of this
Warrant Agreement and the performance of all obligations of the Company
hereunder, including the issuance to Warrantholder of the right to

                                     - 4 -
<PAGE>   5
acquire the shares of Preferred Stock set forth in Section 1, have been duly
authorized by all necessary corporate action on the part of the Company, and the
Loans Agreement and this Warrant Agreement are not inconsistent with the
Company's Charter or Bylaws, do not contravene any law or governmental rule,
regulation or order applicable to it, do not and will not contravene any
provision of, or constitute a default under, any indenture, mortgage, contract
or other instrument to which it is a party or by which it is bound, and the
Loans and this Warrant Agreement constitute legal, valid and binding agreements
of the Company, enforceable in accordance with their respective terms subject
only to bankruptcy, insolvency or other similar laws affecting the
enforceability of the rights of creditors generally and the general principles
of equity.

     (c)  Consents and Approvals. No consent or approval of, giving of notice
to, registration with, or taking of any other action in respect of any state,
Federal or other governmental authority or agency is required with respect to
the execution, delivery and performance by the Company of its obligations under
this Warrant Agreement, except for the filing of notices pursuant to Regulation
D under the 1933 Act and any filing required by applicable state securities law,
which filings will be effective by the time required thereby.

     (d)  Issued Securities. All issued and outstanding shares of Common Stock,
Preferred Stock or any other securities of the Company have been duly authorized
and validly issued and are fully paid and nonassessable. All outstanding shares
of Common Stock, Preferred Stock and any other securities were issued in full
compliance with all Federal and state securities laws. In addition:

          (i)  The authorized capital stock of the Company consists of
26,800,000 shares of Common Stock and 20,800,000 shares of Preferred Stock, of
which 5,000,000 are designated as Series A Preferred Stock, 5,000,000 shares are

Preferred Stock, 3,000,000 shares are designated Series B-1 Preferred Stock,
1,600,000 shares are designated Series C Preferred Stock, and 1,600,000 shares

the Company consists of 1,903,708 shares of Common Stock, 4,627,500 shares of

shall have the rights, preferences, privileges and restrictions set forth in the
Charter.

          (ii) The Company has reserved 1,685,308 shares of its Common Stock for
issuance to officers, directors, employees, sales representatives and
consultants of the Company pursuant to the Company's 1995 Incentive Stock Plan.
There are stock options outstanding for the purchase of 1,215,575 shares of
Common Stock. There are also warrants outstanding for the purchase of 55,000
shares of Common Stock. Except as referenced herein, there are no options,
warrants, conversion privileges or other rights presently outstanding to
purchase or otherwise acquire any authorized but unissued shares of the capital
stock or other securities of the Company.

     (e)  Insurance. The Company has in full force and effect insurance
policies, with extended coverage, insuring the Company and its property and
business against such losses and risks, and in such amounts, as are customary
for corporations engaged in a similar business and similarly situated and as
otherwise may be required pursuant to the terms of any other contract or
agreement.

     (f)  Exempt Transaction. Subject to the accuracy of the Warrantholder's
representations in Section 10 hereof, the issuance of the Preferred Stock upon
exercise of the Warrantholder's right to purchase such Preferred Stock will
constitute a transaction exempt from (i) the registration requirements of
Section 5 of the 1933 Act, in reliance upon Section 4(2) thereof, and (ii) the
qualification requirements of the applicable state securities laws.

     (g)  Compliance with Rule 144. At the written request of the Warrantholder,
who proposes to sell Preferred Stock issuable upon the exercise of the Warrant
in compliance with Rule 144 promulgated by the Securities and Exchange
Commission under the 1933 Act, the Company shall furnish to the Warrantholder,
within ten days after receipt of such request, a written statement confirming
the Company's compliance with the filing requirements of the Securities and
Exchange Commission as set forth in such Rule as then applicable to the Company,
as such Rule may be amended from time to time.

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder which by
its execution hereof the Warrantholder hereby confirms:

     (a)  Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b)  Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)  Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required. Whenever the
restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d)  Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e)  Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act, or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period. The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon

                               WARRANT AGREEMENT

             To Purchase Shares of the Series C Preferred Stock of

                          ARGONAUT TECHNOLOGIES, INC.

                Dated as of July 7, 1998 (the "Effective Date")

               in connection with the Loan and Security Agreement

     WHEREAS, Argonaut Technologies, Inc., a Delaware corporation (the
"Company") has entered into a Loan and Security Agreement dated as of July 7,
1998, (the "Loan Agreement") with Comdisco, Inc., a Delaware corporation (the
"Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Loan Agreement, the right to purchase shares of its Series C Preferred
Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Loan Agreement and in consideration of mutual covenants and
agreements contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe for and purchase, from the Company, 20,000 fully paid and
non-assessable shares of the Company's Series C Preferred Stock ("Preferred
Stock") at a purchase price of $6.00 per share (the "Exercise Price") which is
equivalent to twelve percent (12%) of $1,000,000 divided by the Exercise Price.
Notwithstanding the foregoing, in the event the Company (a) completes (i) an IPO
which results in net cash proceeds to the Company equivalent to, or greater
than, $20,000,000, on or before April 15, 2000; or (ii) an acquisition of the
Company yielding an acquisition price equivalent to or greater than
$100,000,000, and in the case of (i) or (ii) the Company prepays the outstanding
balance of principal and interest under the Loan Agreement within thirty (30)
days of such event; or (b) prepays the outstanding balance of principal and
interest under the Loan Agreement on or before April 15, 2000 in accordance with
the terms of Section 2.6 of the Loan Agreement, then the number of shares
available hereunder shall be adjusted retroactively to equate to nine percent
(9%) of $1,000,000 divided by the Exercise Price. The number and purchase price
of such shares are subject to further adjustment as provided in Section B
hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
or (ii) three (3) years from the effective date of the Company's initial public
offering ("IPO"), whichever is earlier.



                                      -1-

<PAGE>   2
3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time,
prior to the expiration of the term set forth in Section 2 above, by tendering
to the Company at its principal office a notice of exercise in the form
attached hereto as Exhibit 1 (the "Notice of Exercise"), duly completed and
executed, along with this Warrant Agreement. Promptly upon receipt of the
Notice of Exercise, this Warrant Agreement and the payment of the purchase
price in accordance with the terms set forth below, the Company shall issue to
the Warrantholder a certificate for the number of shares of Preferred Stock
purchased.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of the right to purchase such number of
shares equal in value (as determined below) to the aggregate exercise price of
the number of shares to be purchased by the Warrantholder ("Net Issuance"). If
the Warrantholder elects the Net Issuance method, the Company will issue
Preferred Stock in accordance with the following formula:

                    X = Y(A-B)
                        ------
                          A

     Where X =      the number of shares of Preferred Stock to be issued to the
                    Warrantholder.

                    Y =  the number of shares of Preferred Stock requested to be
                         exercised under this Warrant Agreement.

                    A =  the fair market value of one (1) share of Preferred
                         Stock.

                    B =  the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

          (i)  if the exercise is in connection with an initial public offering
     of the Company's Common Stock, and if the Company's Registration Statement
     relating to such public offering has been declared effective by the SEC,
     then the fair market value per share shall be the product of (x) the
     initial "Price to Public" specified in the final prospectus with respect to
     the offering and (y) the number of shares of Common Stock into which each
     share of Preferred Stock is convertible at the time of such exercise;

          (ii)  if this Warrant is exercised after, and not in connection with
     the Company's initial public offering, and:

               (a)  if the Company's Common Stock is traded on a securities
          exchange, the fair market value shall be deemed to be the product of
          (x) the average of the closing prices over a twenty-one (21) day
          period ending three days before the day the current fair market value
          of the securities is being determined and (y) the number of shares of
          Common Stock into which each share of Preferred Stock is convertible
          at the time of such exercise; or

               (b)  If the Company's Common Stock is actively traded
          over-the-counter, the fair market value shall be deemed to be the
          product of (x) the average of the closing bid and asked prices quoted
          on the Nasdaq National Market System (or similar system) over the
          twenty-one (21) day period ending three days before the day the
          current fair market value of the securities is being determined and
          (y) the number of shares of Common Stock into which each share of
          Preferred Stock is convertible at the time of such exercise.

        (iii)  if at any time the Common Stock is not listed on any securities
     exchange or quoted in the Nasdaq National Market System or the
     over-the-counter market, the current fair market value of Preferred Stock
     shall be the product of (x) the highest price per share which the Company
     could obtain from a willing buyer (not a current employee or director) for
     shares of Common Stock sold by the Company, from authorized but unissued
     shares, as determined in good faith by its Board of Directors and (y) the
     number os shares of Common Stock into which each share of Preferred Stock
     is convertible at the time of such



                                      -2-
<PAGE>   3
     exercise, unless the exercise is in connection with a merger, acquisition
     or other consolidation of the Company pursuant to which the Company is not
     the surviving party, in which case the fair market value of Preferred
     Stock shall be deemed to be the value received by the holders of the
     Company's Preferred Stock on a common equivalent basis pursuant to such
     merger or acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number of
shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.

     (a)  Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provided for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b)  Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of the exercise of this Warrant Agreement hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal statute
then enforced, or any state securities law, required by reason of any transfer
involved in such conversion), or listing on any domestic securities exchange,
before such shares may be issued upon conversion, the Company will, at its
expense and as expeditiously as possible, use its best efforts to cause such
shares to be duly registered, listed or approved for listing on such domestic
securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.

     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrantholder's rights to purchase Preferred
Stock, but in lieu of such fractional shares the Company shall make a cash
payment therefor upon the basis of the Exercise Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrantholder's rights to purchase Preferred Stock as provided herein.

7.   WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a)  Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of its rights to purchase
Preferred Stock, the number of shares of Preferred Stock or other securities of
the successor corporation resulting from such Merger Event, to which a holder
of the Preferred Stock deliverable upon exercise of the right to purchase
Preferred stock hereunder would have been entitled in such Merger Event if the
right to purchase such Preferred Stock hereunder had been exercised immediately
prior to the Merger Event. In any such case, appropriate adjustment (as
determined in good faith by the Company's Board of Directors) shall be made in
the application of the provision of this Warrant Agreement with respect to the
rights and interest of the Warrantholder after the Merger Event to the end that
the provisions of this Warrant Agreement (including adjustments of the


                                      -3-

<PAGE>   4
Exercise Price and number of shares of Preferred Stock purchasable) shall be
applicable to the greatest extent reasonably possible.

     (b)  Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of
any other class or classes, this Warrant Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been
issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Warrant Agreement immediately prior
to such combination, reclassification, exchange, subdivision or other change.

     (c)  Subdivision or Combination of Shares. If the Company at any time
shall combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d)  Antidilution Rights. The Preferred Stock purchasable hereunder shall
have the benefit of the same antidilution rights applicable to such Preferred
Stock as designated in the Company's Certificate of Incorporation, as such may
be amended from time to time, and the Company shall provide Warrantholder with
all notices and information at the times and to the extent it is required to do
so to the holders of such Preferred Stock.

     (e)  Notice of Adjustments. If: (i) the Company shall declare any dividend
or distribution upon its stock, whether in cash, property, stock or other
securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any Merger
Event; (iv) there shall be any voluntary dissolution, liquidation or winding up
of the Company; then, in connection with each such event, the Company shall
send to the Warrantholder: (A) at least twenty (20) days' prior written notice
of the date on which the books of the Company shall close or a record shall be
taken for such dividend, distribution, subscription rights (specifying the date
on which the holders of Preferred Stock shall be entitled thereto) or for
determining rights to vote in respect of such Merger Event, dissolution,
liquidation or winding up; and (B) in the case of any such Merger Event,
dissolution, liquidation or winding up, at least twenty (20) days' prior
written notice of the date when the same shall take place (and specifying the
date on which the holders of Preferred Stock shall be entitled to exchange
their Preferred Stock for securities or other property deliverable upon such
Merger Event, dissolution, liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and
(v) the number of shares subject to purchase hereunder after giving effect to
such adjustment, and shall be given by first class mail, postage prepaid,
addressed to the Warrantholder, at the address as shown on the books of the
Company.

     (f)  Timely Notice. Failure to timely provide such notice required by
subsection (e) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.

9.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a)  Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will

taxes, liens, charges or encumbrances of any nature whatsoever; provided,
however, that the Preferred Stock issuable pursuant to this Warrant Agreement
may be subject to restrictions on transfer under state and/or Federal
securities laws. The Company has made available to the Warrantholder true,
correct and complete copies of its Certificate of Incorporation (the "Charter")
and Bylaws, as amended. The issuance of certificates for shares of Preferred
Stock upon exercise of the Warrant Agreement shall be made without charge to
the Warrantholder for any issuance tax in respect thereof, or other cost
incurred by the Company in connection with such exercise and the related
issuance of shares of Preferred Stock; provided that the Company shall not be
required to pay any tax which may be payable in respect of any transfer
involved and the issuance and delivery of any certificate in a name other than
that of the Warrantholder.

     (b)  Due Authority. The execution and delivery by the Company of this
Warrant Agreement and the performance of all obligations of the Company
hereunder, including the issuance to Warrantholder of the right to

                                      -4-

regulation or order applicable to it, do not and will not contravene any
provision of, or constitute a default under, any indenture, mortgage, contract
or other instrument to which it is a party or by which it is bound, and the Loan
Agreement and this Warrant Agreement constitute legal, valid and binding
agreements of the Company, enforceable in accordance with their respective terms
subject only to bankruptcy, insolvency or other similar laws affecting the
enforceability of the rights of creditors generally and the general principles
of equity.

     (c)  Consents and Approvals. No consent or approval of, giving of notice
to, registration with, or taking of any other action in respect of any state,
Federal or other governmental authority or agency is required with respect to
the execution, delivery and performance by the Company of its obligations under
this Warrant Agreement, except for the filing of notices pursuant to Regulation
D under the 1933 Act and any filing required by applicable state securities law,
which filings will be effective by the time required thereby.

     (d)  Issued Securities. All issued and outstanding shares of Common Stock,

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder which by
its execution hereof the Warrantholder hereby confirms:

     (a)  Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b)  Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)  Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition and (ii) if
requested by the Company it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required. Whenever the
restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d)  Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e)  Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act, or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period. The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f)  Accredited Investor. Warrantholder is an "accredited investor" within
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS
AMENDED, OR ANY STATE SECURITIES LAWS. THEY MAY NOT BE SOLD, OFFERED FOR SALE,
PLEDGED, OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
RELATED THERETO OR AN OPINION OF COUNSEL (WHICH MAY BE COMPANY COUNSEL)
REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
SECURITIES LAWS.


                               WARRANT AGREEMENT

             To Purchase Shares of the Series C Preferred Stock of

                          ARGONAUT TECHNOLOGIES, INC.

                Dated as of July 7, 1998 (the "Effective Date")

         in connection with the Receivables Loan and Security Agreement

     WHEREAS, Argonaut Technologies, Inc., a Delaware corporation (the
"Company") has entered into a Receivables Loan and Security Agreement dated as
of July 7, 1998, (the "Receivables Agreement") with Comdisco, Inc., a Delaware
corporation (the "Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Receivables Agreement, the right to purchase shares of its Series C
Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Receivables Agreement and in consideration of mutual covenants
and agreements contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth,
to subscribe for and purchase, from the Company, 16,666 fully paid and
non-assessable shares of the Company's Series C Preferred Stock ("Preferred
Stock") at a purchase price of $6.00 per share (the "Exercise Price") which is
equivalent to five percent (5%) of $2,000,000 divided by the Exercise Price.
The number and purchase price of such shares are subject to adjustment as
provided in Section 8 hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant
Agreement and the right to purchase Preferred Stock as granted herein shall
commence on the Effective Date and shall be exercised for a period of (i) seven
(7) years or (ii) three (3) years from the effective date of the Company's
initial public offering ("IPO"), whichever is earlier.

3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time,
prior to the expiration of the term set forth in Section 2 above, by tendering
to the Company at its principal office a notice of exercise in the form
attached hereto as Exhibit I (the "Notice of Exercise"), duly completed and
executed, along with this Warrant Agreement. Promptly upon receipt of the
Notice of Exercise, this Warrant Agreement and the payment of the purchase
price in accordance with the terms set forth below, the Company shall issue to
the Warrantholder a certificate for the number of shares of Preferred Stock
purchased.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of the right to purchase such number of
shares equal in value (as determined below) to the aggregate exercise price of
the number of shares to be purchased by the Warrantholder ("Net Issuance"). If
the Warrantholder elects the Net Issuance method, the Company will issue
Preferred Stock in accordance with the following formula:


                                      -1-
<PAGE>   2
                    X = Y (A-B)
                        ---------
                            A

     Where: X =     the number of shares of Preferred Stock to be issued to the
                    Warrantholder.

                    Y =  the number of shares of Preferred Stock requested to
                         be exercised under this Warrant Agreement.

                    A =  the fair market value of one (1) share of Preferred
                         Stock.

                    B =  the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

          (i)       if the exercise is in connection with an initial public
     offering of the Company's Common Stock, and if the Company's Registration
     Statement relating to such public offering has been declared effective by
     the SEC, then the fair market value per share shall be the product of (x)
     the initial "Price to Public" specified in the final prospectus with
     respect to the offering and (y) the number of shares of Common Stock into
     which each share of Preferred Stock is convertible at the time of such
     exercise;

          (ii)      if this Warrant is exercised after, and not in connection
     with the Company's initial public offering, and:

                    (a)  if the Company's Common Stock is traded on a securities
          exchange, the fair market value shall be deemed to be the product of
          (x) the average of the closing prices over a twenty-one (21) day
          period ending three days before the day the current fair market value
          of the securities is being determined and (y) the number of shares of
          Common Stock into which each share of Preferred Stock is convertible
          at the time of such exercise; or

                    (b)  if the Company's Common Stock is actively traded
          over-the-counter, the fair market value shall be deemed to be the
          product of (x) the average of the closing bid and asked prices quoted
          on the Nasdaq National Market System (or similar system) over the
          twenty-one (21) day period ending three days before the day the
          current fair market value of the securities is being determined and
          (y) the number of shares of Common Stock into which each share of
          Preferred Stock is convertible at the time of such exercise;

          (iii)     if at any time the Common Stock is not listed on any
     securities exchange or quoted in the Nasdaq National Market System or the
     over-the-counter market, the current fair market value of Preferred Stock
     shall be the product of (x) the highest price per share which the Company
     could obtain from a willing buyer (not a current employee or director) for
     shares of Common Stock sold by the Company, from authorized but unissued
     shares, as determined in good faith by its Board of Directors and (y) the
     number of shares of Common Stock into which each share of Preferred Stock
     is convertible at the time of such exercise, unless the exercise is in
     connection with a merger, acquisition or other consolidation of the Company
     pursuant to which the Company is not the surviving party, in which case the
     fair market value of Preferred Stock shall be deemed to be the value
     received by the holders of the Company's Preferred Stock on a common
     equivalent basis pursuant to such merger or acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number of
shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.

     (a)  Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.


                                     - 2 -

<PAGE>   3
     (b) Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of the exercise of this Warrant Agreement hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal
statute then enforced, or any state securities law, required by reason of any
transfer involved in such conversion), or listing on any domestic securities
exchange, before such shares may be issued upon conversion, the Company will,
at its expense and as expeditiously as possible, use its best efforts to cause
such shares to be duly registered, listed or approved for listing on such
domestic securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.

     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrantholder's rights to purchase Preferred
Stock, but in lieu of such fractional shares the Company shall make a cash
payment therefor upon the basis of the Exercise Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrantholder's rights to purchase Preferred Stock as provided for herein.

7.   WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a)  Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provisions shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of its rights to purchase
Preferred Stock, the number of shares of Preferred Stock or other securities of
the successor corporation resulting from such Merger Event, to which a holder of
the Preferred Stock deliverable upon exercise of the right to purchase
Preferred Stock hereunder would have been entitled in such Merger Event if the
right to purchase such Preferred Stock hereunder had been exercised immediately
prior to the Merger Event. In any such case, appropriate adjustment (as
determined in good faith by the Company's Board of Directors) shall be made in
the application of the provisions of this Warrant Agreement with respect to the
rights and interest of the Warrantholder after the Merger Event to the end that
the provisions of this Warrant Agreement (including adjustments of the Exercise
Price and number of shares of Preferred Stock purchasable) shall be applicable
to the greatest extent reasonably possible.

     (b)  Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of
any other class or classes, this Warrant Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been
issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Warrant Agreement immediately prior
to such combination, reclassification, exchange, subdivision or other change.

     (c)  Subdivision or Combination of Shares. If the Company at any time shall
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.


                                      -3-
<PAGE>   4
     (d)  Antidilution Rights. The Preferred Stock purchasable hereunder shall
have the benefit of the same antidilution rights applicable to such Preferred
Stock as designated in the Company's Certificate of Incorporation, as such may
be amended from time to time, and the Company shall provide Warrantholder with
all notices and information at the times and to the extent it is required to do

of any class of its Preferred or other convertible stock any additional shares
of stock of any class or other rights; (iii) there shall be any Merger Event;

applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.

     (g)  Right to Purchase Additional Stock. In the event the Company has not
repaid all principal and interest due under the Receivables Agreement by the

principal amount of the Loan divided by the Exercise Price.

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder which by
its execution hereof the Warrantholder hereby confirms:

     (a)  Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.


                                      -5-
<PAGE>   6
     (b)  Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)  Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred
Stock or Preferred Stock issuable upon exercise of such rights unless and until
(i) it shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion
of counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act
is available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from
the beneficial owner of any of the aforementioned securities to its nominee or
from such nominee to its beneficial owner, and shall terminate as to any
particular share of Preferred Stock when (1) such security shall have been
effectively registered under the 1933 Act and sold by the holder thereof in
accordance with such registration or (2) such security shall have been sold
without registration in compliance with Rule 144 under the 1933 Act, or (3) a
letter shall have been issued to the Warrantholder at its request by the staff
of the Securities and Exchange Commission or a ruling shall have been issued to
the Warrantholder at its request by such Commission stating that no action
shall be recommended by such staff or taken by such Commission, as the case may
be, if such security is transferred without registration under the 1933 Act in
accordance with the conditions set forth in such letter or ruling and such
letter or ruling specifies that no subsequent restrictions on transfer are
required. Whenever the restrictions imposed hereunder shall terminate, as
hereinabove provided, the Warrantholder or holder of a share of Preferred Stock
then outstanding as to which such restrictions have terminated shall be entitled
to receive from the Company, without expense to such holder, one or more new
certificates for the Warrant or for such shares of Preferred Stock not bearing
any restrictive legend.

     (d)  Financial Risk. The Warrantholder has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e)  Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act", or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period. The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f)  Accredited Investor. Warrantholder is an ""accredited investor" within
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

11.  TRANSFERS.

     Subject to the terms and conditions contained in Section 10 hereof, this
Warrant Agreement and all rights hereunder are transferable in whole or in part
by the Warrantholder and any successful transferee, provided, however, in no
event shall the number of transfers of the rights and interests in all of the
Warrants exceed three (3) transfers. The transfer shall be recorded on the
books of the Company upon receipt by the Company of a notice of transfer in
the form attached hereto as Exhibit III (the "Transfer Notice"), at its

other governmental charges imposed on such transfer.

and/or by action at law, including but not limited to an action for damages as
a result of any such default, and/or an action for specific performance for any

it shall not oppose an application by the Warrantholder or any other person
entitled to the benefit of this Agreement requiring specific performance of any

                               WARRANT AGREEMENT

             To Purchase Shares of the Series C Preferred Stock of

                          ARGONAUT TECHNOLOGIES, INC.

              Dated as of January 19, 1999 (the "Effective Date")

               in connection with the Loan and Security Agreement

     WHEREAS, Argonaut Technologies, Inc. a Delaware corporation (the "Company")
has entered into a Loan and Security Agreement dated as of July 7, 1998, (the
"Loan Agreement") with Comdisco, Inc., a Delaware corporation (the
"Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Loan Agreement, the right to purchase shares of its Series C Preferred
Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Loan Agreement and in consideration of mutual covenants and
agreements contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to the Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth,
to subscribe for and purchase, from the Company, 20,000 fully paid and
non-assessable shares of the Company's Series C Preferred Stock ("Preferred
Stock") at a purchase price of $6.00 per share (the "Exercise Price") which is
equivalent to twelve percent (12%) of $1,000,000 divided by the Exercise Price.
Notwithstanding the foregoing, in the event the Company (a) completes (i) an
IPO which results in net cash proceeds to the Company equivalent to, or greater
than, $20,000,000, on or before April 15, 2000; or (ii) an acquisition of the
Company yielding an acquisition price equivalent to or greater than
$100,000,000, and in the case of (i) or (ii) the Company prepays the
outstanding balance of principal and interest under the Loan Agreement within
thirty (30) days of such event; or (b) prepays the outstanding balance of
principal and interest under the Loan Agreement on or before April 15, 2000 in
accordance with the terms of Section 2.6 of the Loan Agreement, then the number
of shares available hereunder shall be adjusted retroactively to equate to nine
percent (9%) of $1,000,000 divided by the Exercise Price. The number and
purchase price of such shares are subject to further adjustment as provided in
Section 8 hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
or (ii) three (3) years from the effective date of the Company's initial public
offering ("IPO"), whichever is earlier.
<PAGE>   2
3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time,
prior to the expiration of the term set forth in Section 2 above, by tendering
to the Company at its principal office a notice of exercise in the form
attached hereto as Exhibit I (the "Notice of Exercise"), duly completed and
executed, along with this Warrant Agreement. Promptly upon receipt of the
Notice of Exercise, this Warrant Agreement and the payment of the purchase
price in accordance with the terms set forth below, the Company shall issue to
the Warrantholder a certificate for the number of shares of Preferred Stock
purchased.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of the right to purchase such number of
shares equal in value (as determined below) to the aggregate exercise price of
the number of shares to be purchased by the Warrantholder ("Net Issuance"). If
the Warrantholder elects the Net Issuance method, the Company will issue
Preferred Stock in accordance with the following formula:

                    X = Y(A-B)
                        ------
                          A

     Where: X=      the number of shares of Preferred Stock to be issued to the
                    Warrantholder.

                    Y=   the number of shares of Preferred Stock requested to
                         be exercised under this Warrant Agreement.

                    A=   the fair market value of one (1) share of Preferred
                         Stock.

                    B=   the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

          (i)  if the exercise is in connection with an initial public offering
     of the Company's Common Stock, and if the Company's Registration Statement
     relating to such public offering has been declared effective by the SEC,
     then the fair market value per share shall be the product of (x) the
     Initial "Price to Public" specified in the final prospectus with respect to
     the offering and (y) the number of shares of Common Stock into which each
     share of Preferred Stock is convertible at the time of such exercise;

          (ii) if this Warrant is exercised after, and not in connection with
     the Company's initial public offering, and:

               (a)  if the Company's Common Stock is traded on a securities
          exchange, the fair market value shall be deemed to be the product of
          (x) the average of the closing prices over a twenty-one (21) day
          period ending three days before the day the current fair market value
          of the securities is being determined and (y) the number of shares of
          Common Stock into which each share of Preferred Stock is convertible
          at the time of such exercise; or

               (b)  if the Company's Common Stock is actively traded
          over-the-counter, the fair market value shall be deemed to be the
          product of (x) the average of the closing bid and asked prices quoted
          on the Nasdaq National Market System (or similar system) over the
          twenty-one (21) day period ending three days before the day the
          current fair market value of the securities is being determined and
          (y) the number of shares of Common Stock into which each share of
          Preferred Stock is convertible at the time of such exercise;

          (iii) if at any time the Common Stock is not listed on any securities
     exchange or quoted in the Nasdaq National Market System or the
     over-the-counter market, the current fair market value of Preferred Stock
     shall be the product of (x) the highest price per share which the Company
     could obtain from a willing buyer (not a current employee or director) for
     shares of Common Stock sold by the Company, from authorized but unissued
     shares, as determined in good faith by its Board of Directors and (y) the
     number of shares of Common Stock into which each share of Preferred Stock
     is convertible at the time of such


<PAGE>   3
     exercise, unless the exercise is in connection with a merger, acquisition
     or other consolidation of the Company pursuant to which the Company is not
     the surviving party, in which case the fair market value of Preferred Stock
     shall be deemed to be the value received by the holders of the Company's
     Preferred Stock on a common equivalent basis pursuant to such merger or
     acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number
of shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.

     (a)  Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b)  Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of the exercise of this Warrant Agreement hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal
statute then enforced, or any state securities law, required by reason of any
transfer involved in such conversion), or listing on any domestic securities
exchange, before such shares may be issued upon conversion, the Company will,
at its expense and as expeditiously as possible, use its best efforts to cause
such shares to be duly registered, listed or approved for listing on such
domestic securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.

     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrantholder's rights to purchase Preferred
Stock, but in lieu of such fractional shares the Company shall make a cash
payment therefor upon the basis of the Exercise Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrantholder's rights to purchase Preferred Stock as provided for herein.

7.   WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a)  Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of its rights to purchase
Preferred Stock, the number of shares of Preferred Stock or other securities of
the successor corporation resulting from such Merger Event, to which a holder
of the Preferred Stock deliverable upon exercise of the right to purchase
Preferred Stock hereunder would have been entitled in such Merger Event if the
right to purchase such Preferred Stock hereunder had been exercised immediately
prior to the Merger Event. In any such case, appropriate adjustment (as
determined in good faith by the Company's Board of Directors) shall be made in
the application of the provisions of this Warrant Agreement with respect to the
rights and interest of the Warrantholder after the Merger Event to the end that
the provisions of this Warrant Agreement (including adjustments of the


<PAGE>   4
Exercise Price and number of shares of Preferred Stock purchasable) shall be
applicable to the greatest extent reasonably possible.

     (b)  Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of
any other class or classes, this Warrant Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been
issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Warrant Agreement immediately prior
to such combination, reclassification, exchange, subdivision or other change.

     (c)  Subdivision or Combination of Shares. If the Company at any time
shall combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d)  Antidilution Rights. The Preferred Stock purchasable hereunder shall
have the benefit of the same antidilution rights applicable to such Preferred
Stock as designated in the Company's Certificate of Incorporation, as such may
be amended from time to time, and the Company shall provide Warrantholder with
all notices and information at the times and to the extent it is required to do
so to the holders of such Preferred Stock.

     (e)  Notice of Adjustments. If: (i) the Company shall declare any dividend
or distribution upon its stock, whether in cash, property, stock or other
securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any Merger
Event; (iv) there shall be any voluntary dissolution, liquidation or winding up
of the Company; then, in connection with each such event, the Company shall
send to the Warrantholder: (A) at least twenty (20) days' prior written notice
of the date on which the books of the Company shall close or a record shall be
taken for such dividend, distribution, subscription rights (specifying the date
on which the holders of Preferred Stock shall be entitled thereto) or for
determining rights to vote in respect of such Merger Event, dissolution,
liquidation or winding up; and (B) in the case of any such Merger Event,
dissolution, liquidation or winding up, at least twenty (20) days' prior
written notice of the date when the same shall take place (and specifying the
date on which the holders of Preferred Stock shall be entitled to exchange
their Preferred Stock for securities or other property deliverable upon such
Merger Event, dissolution, liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and
(v) the number of shares subject to purchase hereunder after giving effect to
such adjustment, and shall be given by first class mail, postage prepaid,
addressed to the Warrantholder, at the address as shown on the books of the
Company.

     (f)  Timely Notice. Failure to timely provide such notice required by
subsection (e) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.

9.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a)  Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will
be validly issued, fully paid and non-assessable, and will be free of any
taxes, liens, charges or encumbrances of any nature whatsoever; provided,
however, that the Preferred Stock issuable pursuant to this Warrant Agreement
may be subject to restrictions on transfer under state and/or Federal securities
laws. The Company has made available to the Warrantholder true, correct and
complete copies of its Certificate of Incorporation (the "Charter") and Bylaws,
as amended. The issuance of certificates for shares of Preferred Stock upon
exercise of the Warrant Agreement shall be made without charge to the
Warrantholder for any issuance tax in respect thereof, or other cost incurred
by the Company in connection with such exercise and the related issuance of
shares of Preferred Stock; provided that the Company shall not be required to
pay any tax which may be payable in respect of any transfer involved and the
issuance and delivery of any certificate in a name other than that of the
Warrantholder.

     (b)  Due Authority. The execution and delivery by the Company of this
Warrant Agreement and the performance of all obligations of the Company
hereunder, including the issuance to Warrantholder of the right to
<PAGE>   5
acquire the shares of Preferred Stock set forth in Section 1, have been duly
authorized by all necessary corporate action on the part of the Company, and
the Loan Agreement and this Warrant Agreement are not inconsistent with the
Company's charter or Bylaws, do not contravene any law or governmental rule,
regulation or order applicable to it, do not and will not contravene any
provision of, or constitute a default under, any indenture, mortgage, contract
or other instrument to which it is a party or by which it is bound, and the Loan
Agreement and this Warrant Agreement constitute legal, valid and binding
agreements of the Company, enforceable in accordance with their respective terms
subject only to bankruptcy, insolvency or other similar laws affecting the
enforceability of the rights of creditors generally and the general principles
of equity.

     (c)  Consents and Approvals. No consent or approval of, giving of notice
to, registration with, or taking of any other action in respect of any state,
Federal or other governmental authority or agency is required with respect to
the execution, delivery and performance by the Company of its obligations under
this Warrant Agreement, except for the filing of notices pursuant to Regulation
D under the 1933 Act and any filing required by applicable state securities
law, which filings will be effective by the time required thereby.

     (d)  Issued Securities. All issued and outstanding shares of Common Stock,
Preferred stock or any other securities of the Company have been duly authorized
and validly issued and are fully paid and nonassessable. All outstanding shares
of Common Stock, Preferred Stock and any other securities were issued in full
compliance with all Federal and state securities laws. In addition:

          (i)  The authorized capital stock of the Company consists of

     of which 5,000,000 are designated as Series A Preferred Stock, 5,000,000

     B-1 Preferred Stock, 1,600,000 shares are designated Series C Preferred

     issued and outstanding stock of the Company consists 2,299,937 shares of
     Common Stock, 4,627,500 shares of Series A Preferred Stock, no shares of
     Series A-1 Preferred Stock, 2,923,073 shares of Series B Preferred Stock,
     no shares of Series B-1 Preferred Stock, 1,180,000 shares of Series C

     preferences, privileges and restrictions set forth in the Charter.

     otherwise acquire any authorized but unissued shares of the capital stock
     or other securities of the Company.

     (e)  Insurance. The Company has in full force and effect insurance
policies, with extended coverage insuring the Company and its property and

otherwise may be required pursuant to the terms of any other contract or
agreement.

     (f)  Exempt Transaction. Subject to the accuracy of the Warrantholder's
representations in Section 10 hereof, the issuance of the Preferred Stock upon
exercise of the Warrantholder's right to purchase such Preferred Stock will
constitute a transaction exempt from (i) the registration requirements of
Section 5 of the 1933 Act, in reliance upon Section 4(2) thereof, and (ii) the
qualification requirements of the applicable state securities laws.

     (g)  Compliance with Rule 144. At the written request of the Warrantholder,
who proposes to sell Preferred Stock issuable upon the exercise of the Warrant
in compliance with Rule 144 promulgated by the Securities and Exchange
Commission under the 1933 Act, the Company shall furnish to the Warrantholder,
within ten days after receipt of such request, a written statement confirming
the Company's compliance with the filing requirements of the Securities and
Exchange Commission as set forth in such Rule as then applicable to the
Company, as such Rule may be amended from time to time.

<PAGE>   6
10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder which by
its execution hereof the Warrantholder hereby confirms:

     (a)  Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present
intention of selling or engaging in any public distribution of the same except
pursuant to a registration or exemption.

     (b)  Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)  Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred
Stock or Preferred Stock issuable upon exercise of such rights unless and until
(i) it shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion
of counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act
is available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from
the beneficial owner of any of the aforementioned securities to its nominee
or from such nominee to its beneficial owner, and shall terminate as to any
particular share of Preferred Stock when (1) such security shall have been
effectively registered under the 1933 Act and sold by the holder thereof in
accordance with such registration or (2) such security shall have been sold
without registration in compliance with Rule 144 under the 1993 Act, or (3) a
letter shall have been issued to the Warrantholder at its request by the staff
of the Securities and Exchange Commission or a ruling shall have been issued to
the Warrantholder at its request by such Commission stating that no action shall
be recommended by such staff or taken by such Commission, as the case may be, if
such security is transferred without registration under the 1933 Act in
accordance with the conditions set forth in such letter or ruling and such
letter or ruling specifics that no subsequent restrictions on transfer are
required. Whenever the restrictions imposed hereunder shall terminate, as
hereinabove provided, the Warrantholder or holder of a share of Preferred Stock
then outstanding as to which such restrictions have terminated shall be
entitled to receive from the Company, without expense to such holder, one or
more new certificates for the Warrant or for such shares of Preferred Stock not
bearing any restrictive legend.

     (d) Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e) Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "!934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act", or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the rights to purchase, it may be
required to hold such securities for an indefinite period. The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f) Accredited Investor. Warrantholder is an "accredited investor" within
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

11.  TRANSFERS.

     Subject to the terms and conditions contained in Section 10 hereof, this
Warrant Agreement and all rights hereunder are transferable in whole or in part

Warrants exceed three (3) transfers. The transfer shall be recorded on the books
of the Company upon receipt by the Company of a notice of transfer in the form
attached hereto as Exhibit III (the "Transfer Notice"), at its principal offices

construed for all purposes under and in accordance with the laws of the State

party may proceed to protect and enforce its rights either by suit in equity
and/or by action at law, including but not limited to an action for damages as
a result of any such default, and/or an action for specific performance for any
default where Warrantholder will not have an adequate remedy at law and where
damages will not be readily ascertainable. The Company expressly agrees that it
shall not oppose an application by the Warrantholder or any other person
entitled to the benefit of this Agreement requiring specific performance of any
or all provisions hereof or enjoining the Company from continuing to commit any
such breach of this Agreement.

     (g)  No Impairment of Rights. The Company will not, by amendment of its
Charter or through any other means, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate in order to protect the rights
of the Warrantholder against impairment.

     (h)  Survival. The representations, warranties, covenants and conditions
of the respective parties contained herein or made pursuant to this Warrant
Agreement shall survive the execution and delivery of this Warrant Agreement.

     (i)  Severability. In the event any one or more of the provisions of this
Warrant Agreement shall for any reason be held invalid, illegal or
unenforceable, the remaining provisions of this Warrant Agreement shall be
unimpaired, and the invalid, illegal or unenforceable provision shall be
replaced by a mutually acceptable valid, legal and enforceable provision, which
comes closest to the intention of the parties underlying the invalid, illegal or
unenforceable provision.

                                 April 17, 1995

THIS CERTIFIES THAT, for value received, Lease Management Services, Inc.,
("Holder") is entitled to subscribe for and purchase Fifty Thousand (50,000)
shares of the fully paid and nonassessable Common Stock ("the Shares") of
Argonaut Technologies, Inc., a Delaware corporation (the "Company"), at the
Warrant Price (as hereinafter defined), subject to the provisions and upon the
terms and conditions hereinafter set forth. As used herein, the term "Common
Stock" shall mean the Company's presently authorized Common Stock, and any
stock into which such Common Stock may hereafter be exchanged.

1.   Warrant Price. The Warrant Price shall initially be one and 20/100 dollars
($1.20) per share, subject to adjustment as provided in Section 7 below.

2.   Conditions to Exercise. The purchase right represented by this Warrant may
be exercised at any time, or from time to time, in whole or in part during the

     (a)  5:00 P.M. California time on the sixth annual anniversary of this
     Warrant Agreement; or

     (b)  5:00 P.M. California time on the day prior to the effectiveness of a
     registration statement filed in a bona fide firm commitment underwriting
     under the Securities Act of 1933, as amended, covering any of the

     notify the registered Holder of this Warrant of the proposed effective
     date of the merger, consolidation, or sale at least 60 days prior to the

     In the event that, although the Company shall have given notice of a
     transaction pursuant to subparagraph (b) or (c) hereof, the transaction
     does not close on

     approximately the day specified by the Company, unless otherwise elected by
     the Holder any exercise of the Warrant subsequent to the giving of such
     notice shall be rescinded and the Warrant shall again be exercisable until
     terminated in accordance with this Paragraph 2.

3.   Method of Exercise; Payment; Issuance of Shares; Issuance of New Warrant.

(a) Cash Exercise. Subject to Section 2 hereof, the purchase right represented
by this Warrant may be exercised by the Holder hereof, in whole or in part,by
the surrender of this Warrant (with a duly executed Notice of Exercise in the
form attached hereto) at the principal office of the Company (as set forth in
Section 17 below) and by payment to the Company, by check, of an amount equal to
the then applicable Warrant Price per share multiplied by the number of shares
then being purchased. In the event of any exercise of the rights represented by
this Warrant, certificates for the shares of stock so purchased shall be in the
name of, and delivered to, the Holder hereof, or as such Holder may direct
(subject to the terms of transfer contained herein and upon payment by such
Holder hereof of any applicable transfer taxes). Such delivery shall be made
within 10 days after exercise of the Warrant and at the Company's expense and,
unless this Warrant has been fully exercised or expired, a new Warrant having
terms and conditions substantially identical to this Warrant and representing
the portion of the Shares, if any, with respect to which this Warrant shall not
have been exercised, shall also be issued to the Holder hereof within 10 days
after exercise of the Warrant.

(b) Net Issue Exercise. In lieu of exercising this Warrant pursuant to Section
3(a), Holder may elect to receive shares equal to the value of this Warrant (or
of any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with notice of such election, in
which event the Company shall issue to Holder the number of shares of the
Company's Common Stock computed using the following formula:

     X = Y(A-B)
         ------
         A

     Where X = the number of shares of Common Stock to be issued to Holder.

     Y = the number of shares of Common Stock purchasable under this Warrant
         (at the date of such calculation).

     A = the fair market value of one share of the Company's Common Stock (at
         the date of such calculation).

     B = Warrant exercise price (as adjusted to the date of such calculation).

(c)  Fair Market Value. For purposes of this Section 3, Fair Market Value of one
share of the Company's Common Stock shall mean:

     (i)  In the event of an Initial Public Offering pursuant to Section 2(b),
     the per share Fair Market Value for the Common Stock shall be the Offering
     Price at which the underwriters sell Common Stock to the public; or

     (ii) If the Common Stock is traded on NASDAQ or Over-The-Counter or on an
     exchange, the per share Fair Market Value for the Common Stock will be the
     average of the closing bid and asked prices of the Common Stock quoted in
     the Over-The-Counter Market Summary or the closing price quoted on any
     exchange on which the Common Stock is listed, whichever is applicable, as
     published in the Western Edition

Page 3 of 7

     of The Wall Street Journal for the ten (10) trading days prior to the date
     of determination of Fair Market Value; or

     (iii) If the Company shall be subject to a merger, acquisition or other
     consolidation in which the Company is not the surviving entity, pursuant to
     Section 2(c), the per share Fair Market Value for the Common Stock shall be
     the value received per share of Common Stock by all Holders of the Common
     Stock as determined by the Board of Directors; or

     (iv) In any other instance, the per share Fair Market Value for the Common
     Stock shall be as determined by the Board of Directors in its reasonable
     business judgment.

     In the event of 3(c)(iii) or 3(c)(iv), above, the Company's Board of
     Directors shall prepare a certificate, to be signed by an authorized
     Officer of the Company, setting forth in reasonable detail the basis for
     and method of determination of the per share Fair Market Value of the
     Common Stock. The Board will also certify to the Holder that this per share
     Fair Market Value will be applicable to all holders of the Company's Common
     Stock. Such certification must be made to Holder at least thirty (30)
     business days prior to the proposed effective date of the merger,
     consolidation, sale, or other triggering event as defined in 3(c)(iii) or
     3(c)(iv).

(d)  Automatic Exercise. To the extent this Warrant is not previously
exercised, it shall be automatically exercised in accordance with Sections 3(b)
and 3(c) hereof (even if not surrendered) immediately before; (i) its
expiration, (ii) the consummation of a Public Offering of the Company's Common
Stock pursuant to Section 2(b), or (iii) the consummation of any consolidation
or merger of the Company, or any sale or transfer of a majority of a company's
assets pursuant to Section 2(c).

4.   Representations and Warranties of Holder and Restrictions on Transfer
Imposed by the Securities Act of 1933.

(a)  Representations and Warranties by Holder. The Holder represents and
warrants to the Company with respect to this purchase as follows:

     (i)  The Holder has substantial experience in evaluating and investing in
     private placement transactions of securities of companies similar to the
     Company so that the Holder is capable of evaluating the merits and risks of
     its investment in the Company and has the capacity to protect its
     interests.

     (ii) The Holder is acquiring the Warrant and the Shares of Common Stock
     issuable upon exercise of the Warrant (collectively the "Securities") for
     investment for its own account and not with a view to, or for resale in
     connection with, any distribution thereof. The Holder understands that the
     Securities have not been registered under the Act by reason of a specific
     exemption from the registration provisions of the Act which depends upon,
     among other things, the bona fide nature of the investment intent as
     expressed herein. In this connection, the Holder understands that, in the
     view of the Securities and Exchange Commission (the "SEC"), the statutory
     basis for such exemption may be unavailable if this representation was
     predicated solely upon a present intention to hold the Securities for the
     minimum capital gains period specified under tax statutes, for a deferred
     sale, for or until an increase or decrease in the market price of the
     Securities or for a period of one year or any other fixed period in the
     future.

<PAGE>   4
LMSI / Argonaut Technologies, Inc. Warrant
Page 4 of 7

     (iii) The Holder acknowledges that the Securities must be held indefinitely
     unless subsequently registered under the Act or an exemption from such
     registration is available. The Holder is aware of the provisions of Rule
     144 promulgated under the Act ("Rule 144") which permits limited resale of
     securities purchased in a private placement subject to the satisfaction of
     certain conditions, including, in case the securities have been held for
     less than three years, the existence of a public market for the shares, the
     availability of certain public information about the Company, the resale
     occurring not less than two years after a party has purchased and paid for
     the security to be sold, the sale being through a "broker's transaction" or
     in a transaction directly with a "market maker" (as provided by Rule
     144(f)) and the number of shares or other securities being sold during any
     three-month period not exceeding specified limitations.

     (iv) The Holder further understands that at the time the Holder wishes to
     sell the Securities there may be no public market upon which such a sale
     may be effected, and that even if such a public market exists, the Company
     may not be satisfying the current public information requirements of Rule
     144, and that in such event, the Holder may be precluded from selling the
     Securities under Rule 144 unless a) a three-year minimum holding period has
     been satisfied and b) the Holder was not at the time of the sale nor at any
     time during the three-month period prior to such sale an affiliate of the
     Company.

     (v) The Holder has had an opportunity to discuss the Company's business,
     management and financial affairs with its management and an opportunity to
     review the Company's facilities. The Holder understands that such
     discussions, as well as the written information issued by the Company, were
     intended to described the aspects of the Company's business and prospects
     which it believes to be material but were not necessarily a thorough or
     exhaustive description.

(b) Legends. Each certificate representing the Securities shall be endorsed
with the following legend:

          THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933 AND MAY NOT BE TRANSFERRED UNLESS COVERED BY AN EFFECTIVE
          REGISTRATION STATEMENT UNDER SAID ACT, A "NO ACTION" LETTER FROM THE
          SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH TRANSFER, A
          TRANSFER MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND
          EXCHANGE COMMISSION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE
          ISSUER TO THE EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH
          REGISTRATION.

The Company need not register a transfer of Securities unless the conditions
specified in the foregoing legend are satisfied. The Company may also instruct
its transfer agent not to register the transfer of any of the Shares unless the
conditions specified in the foregoing legend are satisfied.

(c) Removal of Legend and Transfer Restrictions. The legend relating to the Act
endorsed on a certificate pursuant to paragraph 4(b) of this Warrant and the
stop transfer instructions with respect to the Securities represented by such
certificate shall be removed and the Company shall issue a certificate without
such legend to the Holder of the Securities if (i) the Securities are
registered under the Act and a prospectus meeting the requirements of Section
10 of the Act is available or (ii) the Holder provides to the Company an
opinion of counsel for the Holder reasonably satisfactory to the Company, or a
no-action letter or interpretive opinion of the staff of the SEC reasonably
satisfactory to the Company, to the effect that public sale,


                                       4
<PAGE>   5
LMSI / Argonaut Technologies, Inc. Warrant
Page 5 of 7

transfer or assignment of the Securities may be without registration and
without compliance with any restriction such as Rule 144.

5. Condition of Transfer or Exercise of Warrant. It shall be a condition to any
transfer or exercise of this Warrant that at the time of such transfer or
exercise, the Holder shall provide the Company with a representation in writing
that the Holder or transferee is acquiring this Warrant and the shares of Common
Stock to be issued upon exercise, for investment purposes only and not with a
view to any sale or distribution, or a statement of pertinent facts covering any
proposed distribution. As a further condition to any transfer of this Warrant or
any or all of the shares of Common Stock issuable upon exercise of this Warrant,
other than a transfer registered under the Act, the Company must have received a
legal opinion, in form and substance satisfactory to the Company and its
counsel, reciting the pertinent circumstances surrounding the proposed transfer
and stating that such transfer is exempt from the registration and prospectus
delivery requirements of the Act. Each certificate evidencing the shares issued
upon exercise of the Warrant or upon any transfer of the shares (other than a
transfer registered under the Act or any subsequent transfer of shares so
registered) shall, at the Company's option, contain a legend in form and
substance satisfactory to the Company and its counsel, restricting the transfer
of the shares to sales or other dispositions exempt from the requirements of the
Act.

     As further conditions to each transfer, the transferee shall receive and
accept a Warrant, of like tenor and date, executed by the Company.

6. Stock Fully Paid; Reservation of Shares. All Shares which may be issued upon
the exercise of the rights represented by this Warrant will, upon issuance, be
fully paid and nonassessable, and free from all taxes, liens, and charges with
respect to the issue thereof. During the period within which the rights
represented by this Warrant may be exercised, the Company will at all times
have authorized, and reserved for issuance upon exercise of the purchase rights
evidenced by this Warrant, a sufficient number of shares of its Common Stock to
provide for the exercise of the rights represented by this Warrant.

7. Adjustment for Certain Events. In the event of changes in the outstanding
Common Stock by reason of stock dividends, split-ups, recapitalizations,
reclassifications, mergers, consolidations, combinations or exchanges of
shares, separations, reorganizations, liquidations, or the like, the number and
class of shares available under the Warrant in the aggregate and the Warrant
Price shall be correspondingly adjusted, as appropriate, by the Board of
Directors of the Company. The adjustment shall be such as will give the Holder
of this Warrant upon exercise for the aggregate Warrant Price the total number,
class and kind of shares as it would have owned had the Warrant been exercised
prior to the event and had it continued to hold such shares until after the
event requiring adjustment.

8. Notice of Adjustments. Whenever any Warrant Price shall be adjusted pursuant
to Section 7 hereof, the Company shall prepare a certificate signed by its
chief financial officer setting forth, in reasonable detail, the event requiring
the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated, and the Warrant Price and number of shares issuable
upon exercise of the Warrant after giving effect to such adjustment, and shall
cause copies of such certificate to be mailed (by certified or registered mail,
return receipt required, postage prepaid) within thirty (30) days of such
adjustment to the Holder of this warrant as set forth in Section 18 hereof.

9. "Market Stand-Off" Agreement. Holder hereby agrees that for a period of 180
days following the effective date of the first registration statement of the
Company covering common stock (or other securities) to be sold on its behalf in
an underwritten public offering, it will not, to the extent requested by the
Company and any underwriter, sell or otherwise


                                       5

Page 6 of 7


transfer or dispose of (other than to donees or transferees who agree to be
similarly bound) any of the Shares at any time during such period except common
stock included in such registration; provided, however, that all officers and
directors of the Company who hold securities of the Company or options to
acquire securities of the Company and all other persons with registration
rights enter into similar agreements.

10.  Transferability of Warrant. This Warrant is transferable on the books of
the Company at its principal office by the registered Holder hereof upon
surrender of this Warrant properly endorsed, subject to compliance with
applicable federal and state securities laws. The Company shall issue and
deliver to the transferee a new Warrant representing the Warrant so
transferred. Upon any partial transfer, the Company will issue and deliver to
Holder a new Warrant with respect to the Warrant not so transferred. Holder
shall not have any right to transfer any portion of this Warrant to any direct
competitor of the Company.

11.  No Fractional Shares. No fractional share of Common Stock will be issued
in connection with any exercise hereunder, but in lieu of such fractional share
the Company shall make a cash payment therefor upon the basis of the Warrant
Price then in effect.

12.  Charges, Taxes and Expenses. Issuance of certificates for shares of Common
Stock upon the exercise of this Warrant shall be made without charge to the
Holder for any United States or state of the United States documentary stamp
tax or other incidental expense in respect of the issuance of such certificate,
all of which taxes and expenses shall be paid by the Company, and such
certificates shall be issued in the name of the Holder.

13.  No Shareholder Rights Until Exercise. This Warrant does not entitle the
Holder hereof to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof.

14.  Registry of Warrant. The Company shall maintain a registry showing the
name and address of the registered Holder of this Warrant. This Warrant may be
surrendered for exchange or exercise, in accordance with its terms, at such
office or agency of the Company, and the Company and Holder shall be entitled
to rely in all respects, prior to written notice to the contrary, upon such
registry.

15.  Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and, in the case of loss, theft,
or destruction, of indemnity reasonably satisfactory to it, and, if mutilated,
upon surrender and cancellation of this Warrant, the Company will execute and
deliver a new Warrant, having terms and conditions substantially identical to
this Warrant, in lieu hereof.

16.  Miscellaneous.

     (a)  Issue Date. The provisions of this Warrant shall be construed and
     shall be given effect in all respect as if it had been issued and delivered
     by the Company on the date hereof.

     (b)  Successors. This Warrant shall be binding upon any successors or
     assigns of the Company.

     (c)  Governing Law. This Warrant shall be governed by and construed in
     accordance with the laws of the State of California.

     (d)  Headings. The headings used in this Warrant are used for convenience
     only and are not to be considered in construing or interpreting this
     Warrant.

Company, as reasonably determined by the Board of Directors of the Company
excluding any director with an interest in such transferee. The Stockholder

the rights granted pursuant to Section 2.1.

     2.3  Termination. The provisions of Sections 2, 3 and 5, including
information rights, rights of first refusal and miscellaneous covenants, shall
terminate upon the closing of a firmly underwritten public offering of the
Common Stock of the Company with a sales price per share (as adjusted for

with aggregate gross proceeds to the corporation, at the public offering price,
of at least $25,000,000, and the provisions of Section 3 shall not be applicable
to such transaction.

                                   SECTION 3

                    Rights of First Refusal On New Issuances

     3.1  Rights of First Refusal. The Company hereby grants to each Stockholder
the right of first refusal to purchase such Stockholder's pro rata portion of
New Securities (as defined in Section 3.1(a)) that the Company may, from time to
time, propose to sell and issue. Such shares of Common Stock held by such
Stockholder (including Common Stock issuable upon conversion of securities
convertible into Common Stock of the Company held by such Stockholder, including
the Preferred) divided by the total number of shares of Common Stock outstanding
at the time of issuance of such New Securities (including Common Stock issuable
upon conversion of all outstanding securities convertible into Common Stock,
including the Preferred). This right of first refusal shall be subject to the
following provisions:

          (a)  "NEW SECURITIES" shall mean any Common Stock of the Company,
whether now authorized or not, and any rights, options, or warrants to purchase
said Common Stock, and securities of any type whatsoever that are, or may
become, convertible into Common Stock; provided, however, that "New Securities"
does not include (i) shares of Common Stock issued upon conversion of the
Preferred Stock; (ii) securities issued pursuant to the acquisition of another
corporation by the Company by merger, purchase of substantially all of the
assets, or other reorganization; (iii) up to 2,500,000 shares and such
additional shares as approved by the unanimous written consent of the Board of
Directors or the unanimous vote of the members of the Company's Board of
Directors present and voting at a duly held meeting (as adjusted for stock
splits, stock dividends or recapitalization) of the Company's Common Stock (or
related options) issued to employees, officers, directors, consultants, or other
persons performing services for the Company (including, but not by way of
limitation, distributors and sales representatives) pursuant to any stock
offering, plan, or arrangement; (iv) securities issued to financial institutions
regularly engaged in the business of the lending money or providing equipment
lease financing in connection with the extension of credit to the Company for
the purpose of financing equipment, inventory, or accounts receivable or in
connection with the lease of equipment and in both cases for other than equity
financing.


                                      -4-
<PAGE>   7
purposes; (v) securities issued to customers or potential customers of the
Company in connection with participation in a product development consortium or
other corporate partner transaction with the Company for purposes which are not
primarily equity financing; or (vi) shares of the Company's Common Stock issued
in connection with any stock split, stock dividend, or recapitalization by the
Company.

          (b)  In the event that the Company proposes to issue New Securities,
it shall give each Stockholder at least thirty (30) days prior written notice of
its intention, describing the type of New Securities, the price, and the general
terms upon which the Company proposes to issue the same. Each Stockholder shall
have twenty (20) days from the date of mailing of any such notice to agree to
purchase its pro rata share of such New Securities for the price and upon the
general terms specified in the notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased.

          (c)  In the event that a Stockholder fails to exercise in full the
right of first refusal within said twenty (20) day period, the Company shall
have seventy-five (75) days thereafter to sell (or enter into an agreement
pursuant to which the sale of New Securities covered thereby shall be closed,
if at all, within thirty (30) days from the date of said agreement) the New
Securities respecting which the Stockholder's rights were not exercised, at a
price and upon general terms no more favorable to the purchasers thereof than
specified in the Company's notice. In the event the Company has not sold the
New Securities within said seventy-five (75) day period (or sold and issued New
Securities in accordance with the foregoing within thirty (30) days from the
date of said agreement), the Company shall not thereafter issue or sell any New
Securities, without first offering such securities to the Stockholders in the
manner provided above.

          (d)  The Stockholder's failure to exercise this right of first
refusal on any issuance of New Securities shall not adversely affect the
Stockholder's right of first refusal to purchase subsequent issuances of New
Securities.

          (e)  The right of first refusal set forth in this Section 3.1 is
nonassignable except to another Stockholder or another entity under common
control with a Stockholder.

     3.2  Termination. The provisions of this Section 3 shall terminate in
accordance with the provisions of Section 2.3.

                                   SECTION 4

                              Registration Rights

     4.1  Requested Registration.

          (a)  Request for Registration. If the Company shall receive from
Initiating Holders a written request that the Company effect any registration,
qualification or compliance with respect


                                      -5-
<PAGE>   8
to not less than forty percent (40%) of the Registrable Securities (or such
lesser percentage of the Registrable Securities if the reasonably anticipated
aggregate price to the public thereof would exceed $5,000,000) the Company will:

          (i)  promptly give written notice of the proposed registration,
qualification or compliance to all other Holders and afford each Holder the
opportunity of including in the registration such Registrable Securities owned
by such Holder; and

          (ii) as soon as practicable, use its best efforts to effect such
registration, qualification or compliance (including, without limitation,
appropriate qualification under applicable blue sky or other state securities
laws and appropriate compliance with applicable regulations issued under the
Securities Act and any other governmental requirements or regulations) as may be
so requested and as would permit or facilitate the sale and distribution of all
or such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within twenty (20) days after receipt of such written notice from
the Company;

          Provided, however, that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 4.1:

          (A)  In any particular jurisdiction in which the Company would be
required to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the Securities
Act;

          (B)  Prior to the earlier to occur of (i) six (6) months after the
effective date of the Company's first registered public offering of its stock or
(ii) December 31, 20001;

          (C)  During the period starting with the sixty (60) days prior to the
Company's estimated date of filing of, and ending on the date six (6) months
immediately following the effective date of, a registration statement in
connection with the initial public offering of securities of the Company,
provided that the Company is actively employing in good faith all reasonable
efforts to cause such registration statement to become effective;

          (D)  During the period starting with the date thirty (30) days prior
to the Company's estimated date of filing of, and ending on the date three (3)
months immediately following the effective date of, any registration statement
pertaining to securities of the Company sold by the Company (other than a
registration of securities in a Rule 145 transaction or with respect to an
employee benefit plan), provided that the Company is actively employing in good
faith all reasonable efforts to cause such registration statement to become
effective;




                                      -6-
<PAGE>   9
          (E)  After the Company has effected two registrations pursuant to this
paragraph 4.1, and such registrations have been declared or ordered effective,
provided that all Registrable Securities requested to be included in each such
registration were in fact included in the registration;

          (F)  If the Company shall furnish to such Holders a certificate signed
by the President of the Company, and concurred to in writing by an underwriter
or other financial advisor of the Company, stating that in the good faith
judgment of the Board of Directors it would be seriously detrimental to the
Company or its stockholders for a registration statement to be filed in the near
future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 4 shall be deferred for a period not to
exceed ninety (90) days from the date of receipt of written request from the
Initiating Holders, provided, however, that the Company shall not utilize this
right more than once in any twelve (12) month period.

          Subject to the foregoing clauses (A) through (F), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable, after receipt of the request or
requests of the Initiating Holders.

     (b)  Underwriting. In the event that a registration pursuant to Section 4.1
is for a registered public offering involving an underwriting, the Initiating
Holders will so advise the Company as part of the written request given by such
Initiating Holders pursuant to Section 4.1(a), and the Company shall in turn
advise the Holders as part of the notice given pursuant to Section 4.1(a)(i). In
such event, the right of any Holder to registration pursuant to Section 4.1
shall be conditioned upon such Holder's participation in the underwriting
arrangements required by this Section 4.1, and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent shall be limited to the
extent provided herein.

     The Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the managing underwriter selected for such underwriting by
the Company, but subject to the reasonable approval of a majority in interest of
the Initiating Holders. Notwithstanding any other provision of this Section 4.1,
if the managing underwriter advises the Initiating Holders in writing that the
number of shares to be underwritten exceeds the number that can be sold in such
offering so as to be likely to have a material adverse effect on the price or
amount at which the Initiating Holders can sell their Shares, then the Company
shall so advise all Holders and Other Holders, and the number of shares that may
be included in the registration and underwriting shall be allocated first among
all Holders in proportion, as nearly as practicable, to the respective amounts
of Registrable Securities held by such Holders at the time of filing the
registration statement and second among the Other Holders in proportion to the
number of shares proposed to be included in such registration by such Other
Holders. No Registrable Securities or other securities excluded from the
underwriting by reason of the underwriter's marketing limitation shall be
included in such registration. To facilitate the allocation of shares in
accordance with the above provisions, the Company or the underwriters may round
the number of shares allocated to any holder to the nearest one hundred (100)
shares.



                                      -7-


<PAGE>   10
          If any Holder of Registrable Securities or Other Holder disapproves
of the terms of the underwriting, such person may elect to withdraw therefrom
by written notice to the Company, the managing underwriter and the Initiating
Holders. The Registrable Securities and/or other securities so withdrawn shall
also be withdrawn from registration.

     4.2  Company Registration

          (a)  Notice of Registration. If at any time or from time to time the
Company shall determine to register any of its securities, either for its own
account or the account of a security holder or holders, other than (i) a
registration relating solely to employee benefit plans, or (ii) a registration
relating solely to a Rule 145 transaction, the Company will:

               (i)  promptly give to each Holder written notice thereof; and

               (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made by any Holder within twenty (20) days after receipt of such
written notice from the Company.

          (b)  Underwriting. If the registration of which the Company gives
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 4.2(a)(i). In such event the right of any Holder to
registration pursuant to Section 4.2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall, together with the
Company and the Other Holders, enter into an underwriting agreement in
customary form with the managing underwriter selected for such underwriting by
the Company. Notwithstanding any other provision of this Section 4.2, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit the
number of shares of Registrable Securities to be included in such registration
without requiring any limitation in the number of shares to be registered on
behalf of the Company, provided that if such underwriting is other than an
initial public offering the number of shares of Registrable Securities held by
Holders and Other Holders to be included in such registration shall not be
limited to less than twenty-five percent (25%) of the total number of shares to
be included in such registration. The Company shall so advise all Holders and
Other Holders and the number of shares that may be included in the registration
and underwriting by all Holders and Other Holders shall be allocated among them,
as nearly as practicable, first, to the Company (or, if applicable, to the
holders for whose account the Company is registering the securities), second,
among the Holders of Registrable Securities in proportion to the respective
amounts of Registrable Securities held by such Holders at the time of filing of
the registration statement, and, third, among the Other Holders in proportion
to the number of shares proposed to be included in such registration by such
Other Holders; provided, however, that at all times, such allocation shall be
subject to the twenty-five percent (25%) threshold set forth in the preceding
sentence if such registration and underwriting is


                                      -8-
<PAGE>   11
other than an initial public offering. To facilitate the allocation of shares
in accordance with the above provisions, the Company may round the number of
shares allocated to any Holder or Other Holder to the nearest one hundred (100)
shares. If any Holder or Other Holder disapproves of the terms of any such
underwriting, such holder may elect to withdraw therefrom by written notice
to the Company and the managing underwriter. Any securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

          (c)  Right to Terminate Registration. The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 4.2 prior to the effectiveness of such registration whether or not any
Holder has elected to include Registrable Securities in such registration.

     4.3  Registration on Form S-3.

          (a) Request for Registration. If any Holder or Holders request that
the Company file a registration statement on Form S-3 (or any successor form to
Form S-3) for a public offering of shares of the Registrable Securities held by
such party the reasonably anticipated aggregate price to the public of which
would exceed $1,000,000 and the Company is a registrant entitled to use Form
S-3 to register the Registrable Securities for such an offering, the Company
shall use its best efforts to cause such Registrable Securities to be
registered for the offering on such form and to cause such Registrable
Securities to be qualified in such jurisdictions as the Holder or Holders may
reasonably request. The substantive provisions of Section 4.1(b) shall be
applicable to each registration initiated under this Section 4.3.

          (b)  Limitations. Notwithstanding the foregoing, the Company shall
not be obligated to take any action pursuant to this Section 4.3: (i) in any
particular jurisdiction in which the Company would be required to execute a
general consent to service of process in effecting such registration,
qualification or compliance unless the Company is already subject to service in
such jurisdiction and except as may be required by the Securities Act; (ii)
with respect to Section 4.3 only, for a period of one hundred twenty (120) days
after receipt of the request of the initiating Holders, if the Company, within
ten (10) days after such receipt gives notice of its bona fide intention to
effect the filing of a registration statement with the Commission within ninety
(90) days of receipt of such request (other than with respect to a registration
statement relating to a Rule 145 transaction, an offering solely to employees
or any other registration which is not appropriate for the registration of
Registrable Securities) and the Company shall promptly notify the initiating
Holders in the event it abandons its intention to effect such registration
statement; (iii) during the period starting with the date sixty (60) days prior
to the Company's estimated date of filing of, and ending on the date six (6)
months immediately following, the effective date of any registration statement
pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit
plan), provided that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective
and, provided further that the Company shall have the right to defer filing a
registration statement under the Securities Act not more than one in any twelve
month period; or (iv) if the Company shall furnish to such Holder a

                                      -9-
<PAGE>   12
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or the stockholders as a whole for registration statements to be
filed in the near future, then the Company's obligation to use its best efforts
to file a registration statement shall be deferred for a period not to exceed
ninety (90) days from the receipt of the request to file such registration by
such Holder, provided, however, that the Company shall not utilize this right
more than once in any twelve (12) month period.

     4.4  Limitations on Subsequent Registration Rights. From and after the date
hereof, the Company, will not, without the prior written consent of holders of a
majority of the voting power of the then outstanding Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company which allows such holder or prospective holder of any securities
of the Company to include such securities in any registration filed under
Sections 4.1, 4.2 or 4.3 hereof, unless, under the terms of such agreement, such
holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of his securities will not
diminish the amount of Registrable Securities which are included. However, the
Company may by agreement grant such holder or prospective holder a registration
right analogous to that set forth in Section 4.1 provided that (i) such holder
or prospective holder may not demand a registration analogous to that set forth
in Section 4.1 at any time earlier than the Holders first have such right, and
(ii) that the Registrable Securities may be included in any such registration
demanded by such holders to the extent such inclusion will not diminish the
amount of securities of such holders which are included.

     4.5  Expenses of Registration.

          (a)  Registration Expenses. The Company shall bear all Registration
Expenses incurred in connection with all registrations pursuant to Section 4.1
or Section 4.2 and up to four registrations pursuant to Section 4.3.

          (b)  Selling Expenses. Unless otherwise stated in Section 4.5(a), all
Selling Expenses and Registration Expenses relating to securities registered on
behalf of the Holders shall be borne by the Holders pro rata on the basis of the
number of shares so registered by such Holder.

     4.6  Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company will:

          (a)  keep each Holder advised in writing as to the initiation of each
registration, qualification and compliance and as to the completion thereof;

          (b)  as soon as practicable, prepare and file with the Commission a
registration statement with respect to such securities and use its best efforts
to cause such registration statement to become and remain effective until the
earlier of (i) one hundred twenty (120) days or (ii) the distribution described
in the Registration Statement has been completed; provided, however, that (i)
such 120-day period shall be extended for a period of time equal to the period
the Holder refrains



                                      -10-

<PAGE>   13
from selling any securities included in such registration at the request of an
underwriter of Common Stock (or other securities) of the Company; and (ii) in
the case of any registration of Registrable Securities on Form S-3 which are
intended to be offered on a continuous or delayed basis, such 120-day period
shall be extended, if necessary, to keep the registration statement effective
until all such Registrable Securities are sold, provided that Rule 145, or any
successor rule under the Securities Act, permits an offering on a continuous or
delayed basis, and, provided further, that applicable rules under the
Securities Act governing the obligation to file a post-effective amendment
permit, in lieu of filing a post-effective amended which (I) includes any
prospectus required by Section 10(a)(3) of the Securities Act or (II) reflects
facts or events representing a material or fundamental change in the

reference of information required to be included in (I) and (II) above to be
contained in periodic reports filed pursuant to Section 13 or 15(d) of the
Exchange Act in the registration statement;

          (c)  furnish to the Holders participating in such registration and to
the underwriters of the securities being registered such reasonable number of
copies of the registration statement, preliminary prospectus, final prospectus
and such other documents as such underwriters may reasonably request in order
to facilitate the public offering of such securities;

          (d)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement;

          (e)  in the event of an underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement;

          (f)  notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating hereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of material fact or omits to state
a material fact required to be stated therein or necessary to make the
statements made therein not misleading in the light of the circumstances then
existing;

          (g) provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such

Securities under such other securities or blue sky laws of such jurisdictions
as any Holder reasonably requests and do any and all other acts and things
which may be necessary or advisable to enable such holder to consummate the

seller;



                                      -11-
<PAGE>   14
provided, that the Company will not be required to (i) qualify generally to do
business in any jurisdiction where it would not otherwise be required to
qualify but for this paragraph (d), (ii) subject itself to taxation in any such
jurisdiction or (iii) consent to general service or process in any such
jurisdiction, but the Company will be required to consent to service or process
in actions arising out of or in connection with the sale of the Registrable
Securities or any violation of state securities laws;

          (i)  use its best efforts to cause the Registrable Securities covered
by such registration statement to be registered with or approved by any other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company to enable the seller or sellers thereof
to consummate the disposition of such Registrable Securities;

          (j)  use its best efforts to obtain a comfort letter from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by comfort letters with respect to
offerings of such type as the Holders may reasonably request;

          (k)  otherwise comply with all applicable rules and regulations of
the Commission, and make available to its security holders, as soon as
reasonably practicable, an earnings statement covering a period of twelve
months, beginning within three months after the effective date of the
registration statement, which earnings statement shall satisfy the provisions
of Section 11(a) of the Securities Act and rule 158 thereunder; and

          (l)  cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed, provided that the applicable listing requirements are satisfied.

          The Company may require each holder of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding the distribution of such Registrable Securities as the
Company may from time to time reasonably request in writing.

     4.7  Preparation: Reasonable Investigation.

     In connection with the preparation and filing of each registration
statement under the Securities Act pursuant to this Agreement, the Company will
give each Holder of Registrable Securities, their underwriters, if any, and
their respective counsel and accountants, the opportunity to participate in the
preparation of such registration statement, each prospectus included therein or
filed with the Commission, and each amendment, thereof or supplement thereto,
and will give each of them such access to its books and records and such
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of such Holders' and such underwriters'
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

     4.8  Indemnification.

          (a)  By Company. The Company will indemnify and hold harmless each
Holder, each of its officers and directors and partners, and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification or compliance has been
effected pursuant to this Agreement, and each underwriter, if any, and each
person who controls any underwriter within the meaning of Section 15 of the
Securities Act and each Stockholder and its officers, directors and partners
and each person controlling such Stockholder within the meaning of Section 15
of the Securities Act, against all expenses, claims, losses, damages or
liabilities, joint or several, (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, or any
violation by the Company of the Securities Act, the Exchange Act or any state
or federal securities law, or any rule or regulation promulgated under such
Acts or law applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each such Holder,
each of its officers, directors and partners, and each person controlling such
Holder, each such underwriter and each person who controls any such
underwriter, each Stockholder, each of its officers, directors and partners and
each person controlling such Stockholder, in advance of the final disposition
of such matter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in
any such case to any such Holder to the extent that any such claim, loss,
damage, liability or expense arises out of or is based on any untrue statement
or omission or alleged untrue statement or omission, made in reliance upon and
in conformity with written information furnished to the Company by an
instrument duly executed by such Holder, controlling person, underwriter or
Stockholder and stated to be specifically for use therein. If the Holders and
Stockholders are represented by counsel other than counsel for the Company, the
Company will not be obligated under this Section 4.7(a) to reimburse legal fees
and expenses of more than one separate counsel for all Holders and Stockholders.

          (b)  By Holders. Each Holder will, if Registrable Securities held by
such Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify and hold harmless the
Company, each of its directors, each of its officers, each underwriter, if any,
of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, and each other such Holder, each of its
officers and directors and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, against all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any such registration statement, prospectus, offering circular or
other document, or any omission (or alleged omission) to state therein a
material


                                      -13-
<PAGE>   16
fact required to be stated therein or necessary to make the statements therein
not misleading, and will reimburse the Company, such Holders, such directors,
officers, persons, underwriters or control persons for any legal or any other
expenses reasonably incurred in connection with investigating or defending any
such claim, loss, damage, liability or action, in each case to the extent, that
only to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein.
Notwithstanding the foregoing, the liability of each Holder under this
subsection (b) shall be limited in an amount equal to the public offering price
of the Registrable Securities sold by such Holder, unless such liability arises
out of or is based on willful misconduct by such Holder.

     (c)  Procedures. Each party entitled to indemnification under this Section
4.8 (the "Indemnified Party") shall given written notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnify may
be sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement unless the failure
to give such notice is materially prejudicial to an Indemnifying Party's
ability to defend such action and provided further, that the Indemnifying Party
shall not assume the defense for matters as to which there is conflict of
interest or separate and different defenses. No Indemnifying Party, in the
defenses of any such claim or litigation, shall, except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving
by the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation.

     (d)  Contribution. If the indemnification provided for in this Section 4.8
is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party or is insufficient with respect to any loss, liability,
claim, damage, or expense referred to therein, then the indemnifying party, in
lieu of indemnifying such indemnified party hereunder, shall contribute to the
amount paid or payable by such indemnified party as a result of such loss,
liability, claim, damage, or expense in such proportion as it appropriate to
reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements or omissions
that resulted in such loss, liability, claim, damage, or expense as well as any
other relevant equitable considerations. The relative fault of the indemnifying
party and of the indemnified party shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative
intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a party as a result
of any loss, liability, claim, damage or expense referred to above shall



                                      -14-

<PAGE>   17
be deemed to include, subject to the limitations set forth in Section 4.8(c),
any legal or other fees, or expenses reasonably incurred by such party in
connection with any investigation or proceeding. If indemnification is
available under this Section 4.8, the indemnifying parties shall indemnify each
indemnified party to the full extent provided in Section 4.8(a) and (b) without
regard to the relative fault of said indemnifying party or indemnified party or
other equitable consideration provided for in this Section 4.8(d).

          (e)  Controlling Agreement. Notwithstanding the foregoing, to the
extent that the provisions on indemnification and contribution contained in the
underwriting agreement entered into in connection with the underwritten public
offering are in conflict with the foregoing provisions of this Section 4.8, the
provisions in the underwriting agreement shall control.

     4.9  Information by Holder. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held
by them and the distribution proposed by them as the Company may request in
writing and only as shall be necessary to enable the Company to comply with the
provisions hereof in connection with any registration, qualification or
compliance referred to in this Agreement.

     4.10 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Registrable Securities to the public without registration, after
such time as a public market exists for the Common Stock of the Company, the
Company agrees to use its best efforts to:

          (a)  Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Exchange Act.

          (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements);

          (c)  Furnish to any Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of Rule 144
(at any time after 90 days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Exchange Act (at any time after it
becomes subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
of the Company and other information in the possession of or reasonably
obtainable by the Company as such Holder may reasonably request in availing
itself of any rule or regulation of the Commission allowing such Holder to sell
any such securities without registration.

     4.11  Transfer of Registration Rights. The rights to cause the Company to
register securities granted Holders under Sections 4.1, 4.2 and 4.3 may be
assigned in connection with any transfer or assignment by a Holder of
Registrable Securities provided that: (i) such transfer may otherwise be
effected in accordance with applicable securities laws, (ii) such transfer is
effected in compliance with the restrictions on transfer contained in this
Agreement and in any other agreement between the Company and the Holder, and
(iii) such assignee or transferee is a constituent partner of a Stockholder or
purchases (a) at least 125,000 shares of Preferred or Common Stock into which
such Preferred has been converted or (b) all shares of Preferred and Common
Stock, into which such Preferred has been converted, held by a Stockholder. No
transfer or assignment will divest a Holder or any subsequent owner of such
rights and powers unless all Registrable Shares are transferred or assigned.

     4.12  Termination. The registration rights granted pursuant to this Section
4 shall terminate as to any Holder at the later of (i) five years after the
Company's initial public offering or (ii) after the effective date of the
Company's first registered public offering of its stock, at such time as such
Holder may sell under Rule 144, or a successor rule, in a three month period all
Registrable Securities then held by such Holder.

     4.13  Lockup Agreement. Each Holder agrees that, if, in connection with the
Company's initial public offering of the Company's securities, the Company or
the underwriters managing the offering so request, the Holder shall not sell,
make any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any Registrable Securities (other than those included in the
registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed one
hundred eighty (180) days) from the effective date of such registration as may
be requested by the Company or the underwriters; provided that each officer and
director of the Company who owns stock of the Company also agrees to such
restrictions. This Section 4.13 shall be binding on all transferees or assignees
of Registrable Securities, whether or not such persons are entitled to
registration rights pursuant to Section 4.11.

     4.14  Representations and Warranties of the Company. The Company represents
and warrants to each of the Stockholders as follows:

          (i)  The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all requisite corporate action and will not
violate any provision of law, any order of any court or other agency of
government, the Restated Certificate or By-laws of the Company or any provision
of any indenture, agreement or other instrument to which it or any or its
properties or assets is bound, conflict with, result in a breach of or
constitute (with due notice or lapse of time or both) a default under any such
indenture, agreement or other instrument or result in the creation or imposition
of any lien, charge or encumbrance of any nature whatsoever upon any of the
properties or assets of the Company.

Board of Directors, the Company shall require all future officers, directors

the Company's proprietary or confidential information and the assignment of
intellectual property rights to the Company.

Company's Common Stock or options to purchase the Company's Common Stock
receiving such securities in connection with the performance of services for
the Company to execute and deliver agreements providing that such Common Stock
shall be subject to a right of the Company to repurchase such Common Stock at
the original purchase price in the event that the relationship of such person
with the Company is terminated, which right shall lapse over a four-year

four-year period based upon continuing employment, or providing such other
vesting arrangements as determined appropriate by the Company's Board of
Directors.

     5.3  Changes in Common Stock or Preferred Stock. If, and as often as,
there is any change in the Common Stock or the Preferred by way of a stock
split, stock dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any other means,
appropriate adjustment shall be made in the provisions hereof so that the
rights and privileges granted hereby shall continue with respect to the Common
Stock or the Preferred as so changed.

     5.4  Board of Directors. At each election of the Board of Directors of the

representative shall be designated by holders of a majority in interest of the

member of the Board of Directors, the Company and the Stockholders agree to
take all such action as is reasonable and necessary, including the voting of
shares of capital stock of the Company by the Stockholders as to which they
have beneficial ownership, to cause the election or appointment of such other
substitute person to the Board of Directors as may be designated pursuant to
this Section 5.4.

counterparts, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

David P. Binkley, Ph.D.

Ridgefield, CT 06877

Dear Dave,

This letter supersedes any similar such letters on the same subject of prior
date.

The Board of Directors and employees of ARGONAUT TECHNOLOGIES, INC. are very
excited and pleased about you becoming our President, Chief Executive Officer
and Board member. We are unanimous in the belief that you can lead the Company
in its move forward toward worldwide prominence. This letter is a formal offer
to join the Company.

Your initial salary for the position will be $17,667 per month, an 8% increase
over your current salary. Your salary will be reviewed annually. The first
review will be in January 1998 and adjustments will be based on performance.
You will also receive a bonus plan that will provide you the opportunity of
earning up to 40% of your base salary in additional cash compensation based
upon achieving milestones to be established by you and the Board. You will be
eligible for this bonus annually (to be reviewed and paid in each January for
the prior calendar year) beginning in January 1998.

You will be granted an option to purchase 500,000 shares of common stock at a
price equal to the fair market value on the date of grant, which is currently
$0.30 per share for common stock. We sold preferred stock in our last financing
round at $3.25 per share. This share amount represents more than 50% above any
other officer in the Company. Your shares will vest monthly over 48 months based
upon your continued employment, however the first six months of vesting will be
accelerated so that one eighth (62,500 shares) will be fully vested to you upon
commencement of employment and the remainder will begin vesting after your
initial six months with the Company.

To facilitate your relocation, you may receive reimbursement of moving expenses
(to include transportation, house selling costs, house purchase closing fees)
of up to $100,000. The Company will also make available a loan of up to $300,000
to further assist you in purchasing a home in this area. This loan will be held
as a second mortgage and due in five years or sooner in the event of
termination of your employment. The interest rate on this loan will be the
minimum rate allowable under Internal Revenue Service regulations (currently
approximately 6%), and will be fixed on the date the note is signed. You may
pay off this loan at any time. In the event of the Company's termination of
your employment without cause, you would receive twelve month's base salary as
severance.

The employee benefit package will be sent to you under a separate cover from
the Company. The component parts are medical, dental, long term disability,
life insurance, two weeks paid vacation, and 401K plan that is non-matching
until the Company is profitable.

In the event the Company is acquired by or merged into another company, if you
are not offered a position of similar responsibility and leave, the Board of
Directors will waive its right to repurchase the remaining of your unvested
shares and, therefore, you would be able to keep them.

This is not an employment contract for any specified duration. Accordingly,
your employment may be terminated by you or by us at any time, with or without
cause. This offer is contingent upon your signing of the Argonaut Proprietary
Information and Invention Assignment Agreement which will be sent to you under
separate cover. The terms of this offer are considered confidential information
to ARGONAUT TECHNOLOGIES, INC., and we trust that you will treat it
confidentially as between you and the Board of Directors.

If you have any questions about this offer, please contact me at 415-233-3322.
If you accept the offer, please sign this offer letter where indicated and
return it to me at your earliest convenience.

Dave, I speak for the Board of Directors and employees of the Company when I
say that we are looking forward to building a mutually rewarding business
relationship.

We are looking forward to having you join the ARGONAUT TECHNOLOGIES team.

Sincerely,

/s/ BROOK H. BYERS

base rental of $30,934.00 per month in advance, commencing with the first day of
said term and on the same day of each succeeding month thereof. Receipt of the
first month's rent in the amount of $-0- is hereby acknowledged.

B.   As consideration for the execution of this lease, the Lessee shall pay to
the Lessor the sum of $30,934.00*, receipt of which is hereby acknowledged. In
the event Lessee is not then in default under the terms of this lease, said sum
of $30,934.00 shall be applied toward the rental due for the last one month of
the term hereof. If this lease is extended, said consideration, if Lessee is not
then in default, shall be applied toward rental due for the last month of the
extended term, in lieu of the last month of the initial term. * see paragraph 9

C.   The base rental above set forth shall be subject to escalation as follows:

continuing thereafter for each remaining twelve (12) month lease period (and for
the last months of the term if said period is less than twelve (12) months),

ratio that the average monthly Index for the previous twelve (12) months
preceding the month in which such rental period commences, shall have increased

basis from local lending agencies; but if such repairs cannot be so made, then
this lease, at the option of Lessor, shall terminate; but if not so terminated,

his option, and in addition to any other rights he may have, may re-enter and
repossess said premises and remove all property therefrom and store the same at
the expense of Lessee. Lessor, upon default of Lessee, may relet said premises
or any portion thereof, in a changed condition or otherwise, for such rental
and upon such terms as he deems reasonable, and hold Lessee for the difference
received, plus expenses of reletting and collecting such rental, and the rental
herein provided. No such re-entry or taking of possession by Lessor shall be
deemed an election to terminate this lease unless Lessee is served with notice
of said termination by Lessor or the same be decreed by a court of competent
jurisdiction.

     In the event Lessee shall breach this lease and abandon the demised
premises, Lessor may also elect to continue the lease in effect and Lessor may
enforce all rights and remedies hereunder, including the right to recover rent
as it becomes due, all pursuant to the provisions of Section 1951.4 of the
California Civil Code. In the event of such election by Lessor to continue the
lease, Lessee hereby irrevocably appoints Lessor the agent of Lessee to enter
upon the demised premises and remove any and all persons and/or property
whatsoever situated upon said premises, and to place all or any portion of said
property, except such property as may become the property of Lessor, in storage
for the account of and at the expense of Lessee; and, in such case, Lessor may
relet the demised premises upon such terms as to it may seem fit, and if a
sufficient sum shall not be thus realized, after paying expenses of such
reletting and collecting, to satisfy the rent and such other sums as may be
reserved herein to be paid, Lessee shall satisfy and pay any deficiency, and
pay the expenses of such reletting and collecting. Lessee hereby releases
Lessor and agrees to save harmless Lessor from any cost, loss or damage arising
out of or caused by any such entry or reentry upon the demised premises and/or
the removal of persons and/or property and storage of such property by Lessor
or his agents.

     Lessee hereby grants to Lessor a security interest in all its fixtures,
machinery, equipment, presently owned by Lessee and located at said demised
premises. While Lessee is not in default in the payment of rent or any of its
obligations under this Lease, it may trade in or replace any of said items free
of this security interest and the security interest shall then apply to the
newly acquired items. All trade fixtures, equipment and other like property
which the Lessee has installed in the building shall remain the property of the
Lessee, subject to Lessor's security interest, and the Lessor agrees that the
Lessee shall have the option at any time, and from time to time, provided the
Lessee is not then in default in the performance of any of the obligations of
the lease on its part to be performed, to trade in or replace any and all of its

like property which it may have installed in the building or improvements, and

other reasonable counsel fees in said action or proceeding as fixed by the
court.

     In the event Lessee is in default in payment of rent for any period or in
Lessee's performance of any covenant hereof, and the Lessor engages an attorney

therein (if any) and tax reimbursement. This paragraph shall in no sense imply
any consent by Lessor to such holding over.

     16. NOTICES TO LESSEE. All notices required by law or this lease to be
given to Lessee by Lessor may be given personally to Lessee or mailed to him
by United States mail, postage prepaid and addressed to Lessee at the premises,

interest of Lessee in such premises and this lease, at the opinion of Lessor,
shall terminate in the event of levy of execution against Lessee upon such
interest (provided Lessee fails for a period of five (5) days to discharge or
bond against said levy), or upon Lessee filing or having filed against him

or removing of said signs or other equipment on the roof or other portions of
the premises. Lessee may place professionally designed signs in and on said
building advertising Lessee's business after written approval by Lessor, and

     21.  SURRENDER OF PREMISES. Lessee agrees to surrender the premises at the

lease, Lessor may require any or all of the alterations or additions installed

4 hereof. *See paragraph 34

     22.  SUCCESSORS AND ASSIGNS. The covenants and conditions herein
contained, subject to the provisions as to assignment, shall apply to and bind
the heirs, executors, administrators, successors and assigns of Lessor and
Lessee. The term "Lessor" as used herein shall mean only the owner or owners at
the time in question of the fee title or a Lessee's interest in a ground lease
of the Premises, and except as expressly herein provided, in the event of any
transfer of such title or interest, Lessor herein named (and in case of any
subsequent transfers the then grantor) shall be relieved from and after the
date of such transfer of all liability as respects Lessor's obligations
thereafter to be performed, provided that any funds in the hands of Lessor or
the then grantor at the time of such transfer, in which Lessee has an interest,
shall be delivered to the grantee. The obligations contained in this Lease to
be performed by Lessor shall, subject as aforesaid, be binding on Lessor's
successors and assigns, only during their respective periods of ownership.

     23.  TIME. Time is of the essence of this lease.

     24.  RECORDING. This lease shall not be recorded by Lessee, but in the
event the interest of Lessee herein is shown as an exception to title in any
title company report of title, Lessee agrees to execute and deliver to Lessor a
quitclaim deed covering all Lessee's interest in said premises, forthwith upon
termination of this lease.

     25.  TAX INCREASES. Lessee agrees to pay Lessor the amount of any increase
in city, county and district real estate taxes assessed against said premises,
in excess of the taxes for the fiscal year 1999 - 2000. Included in "taxes"
shall be any levy, tax, charge or fee levied by a governmental entity on
parking spaces or privileges or parking uses in the leased premises and any tax
on Lessor's gross rental receipts (other than income tax).

     Also included in said taxes shall be any future special assessments for
local improvements of any sort. If said assessments are permitted to go to
bond, the total amount of the annual installment shall be added to the tax bill
for the purpose of the computation of any increase in taxes; if Lessor
discharges said assessment and does not permit the same to go to bond, the
amount which each annual installment, less interest, would have been if the
same had gone to bond, shall be annually added to Lessor's tax bill for the
purpose of tax increase computation.

     Lessee shall pay Lessor the amount of any such increase in real property
taxes, as above defined, in two equal installments, one on December 1 and the
other on April 1 of the said fiscal tax years. Submission of copies of tax
bills by Lessor shall be evidence of and notice of the amount of said taxes.
The amount of said increase shall be prorated in the event this lease commences
or terminates during any fiscal tax year, and in such event the split-period,
proratable semi-annual installment of the tax increase shall be paid either
thirty (30) days prior to the termination of this lease or within ten (10) days
of notification by the Lessor to the Lessee of the amount of said increase.

     In the event said tax reimbursement payments are not made to Lessor on or
before the dates herein set forth, the Lessee shall pay to Lessor a ten percent
(10%) per annum late charge for such delinquency to be added to the tax
reimbursement payment due. If said taxes and assessments are assessed against
the entire building and building site, the taxes and assessments allocated to
the leased premises shall be prorated on a square footage or other equitable
basis, as calculated by Lessor.

     If the assessed value of the Lessor's premises is increased by the
inclusion therein of a value placed upon the personal property or improvements
of the Lessee, and if the Lessor pays the taxes based on such increased
assessment, the Lessee shall, upon demand, repay to the Lessor the portion of
such taxes resulting from such increase in assessment.

     26.  OUTSIDE STORAGE. No materials, supplies, equipment, finished products
or semi-finished products, raw materials or articles of any nature shall be
stored upon or permitted to remain on any portion of the leased premises
outside of the building constructed thereon, except with the prior written
consent of the Lessor.

     No waste materials or refuse shall be dumped upon or permitted to remain
unreasonably upon any part of the leased premises outside of building proper,
unless approved by Lessor.

     27.  OTHER RULES. Lessor reserves the right to make such other reasonable
rules and regulations, including parking regulations, as in Lessor's judgment
may from time to time be necessary for the safety, cleanliness and orderly
operation of the leased premises for the benefit of all the tenants in the
area. Lessee agrees to require its employees, executive, invitees and customers
to abide by such results and regulations, including parking regulations.

building area or more than twenty per cent (20%) of the surrounding land in the
demised premises shall be condemned by any public authority under eminent
domain, this lease shall terminate and the award for damages shall belong
entirely to Lessor, except as to trade fixtures of Lessee. If a lesser portion
of the premises be condemned, the Lessee shall be entitled to a reasonable
abatement of rent proportionate to the loss of use of space being leased. The
granting by Lessor of storm drainage or utility easements over the demised
premises shall not involve any reduction in rent, unless such easements
materially affect Lessee's use of the demised premises.

     29.  NOTICES TO LESSOR. All notices required by law or this lease to be
given to Lessor by Lessee shall be mailed to Lessor, registered or certified
mail, return receipt requested, by United States Mail, postage prepaid to Lessor

Lessor shall maintain the roof and structural components of the leased
premises, such duty to repair being subject to the condition precedent that
Lessee shall give prior written notice of at least 24 hours to Lessor (during
working hours) specifying the need for such repairs. Structural components are
defined as outside walls (excluding windows, doors, doorframes, storefront,
glazing, door closers, locks and hardware), footings, columns, floor slab, and

have been included in this lease as attachments thereto: No. 32, 33, 34, 35, 36,

<PAGE>   4
ARTICLE 4 - PAYMENTS AND REPORTS

     4.01 For the rights granted under this Agreement, LICENSEE shall pay to
LICENSOR an initial sum of One Thousand Dollars ($1000), payable upon signing
of this Agreement, and royalties calculated as follows:

calendar quarter shall be due and payable with the report for that quarter. Any
late payment of the royalty shall bear interest at the rate of one-and-one-half
percent (1 1/2%) per month.

     4.03 All payments and reports shall be sent to the following address:

               Philadelphia, PA 19178

     4.04 LICENSEE shall maintain sufficiently detailed books and records for
the PRODUCTS sold or used by LICENSEE and AFFILIATES to enable LICENSOR to

accountant, appointed by LICENSOR and reasonably acceptable to LICENSEE, to
inspect, at reasonable times and upon reasonable notice, but not to exceed once
per year, the books and records of LICENSEE relating to the sale of the

<PAGE>   5
PRODUCTS for use in the FIELD. The accountant shall report to LICENSOR only
whether the amounts reported and paid to LICENSOR by LICENSEE are accurate. In
no event, however, shall an examination of LICENSEE's books be made for a period
prior to three (3) years before the date such audit is requested by LICENSOR. In
the event the accountant reports to LICENSOR that LICENSEE has underpaid the
amounts due to LICENSOR by more than ten percent (10%), LICENSEE shall bear the
cost of the audit.

     4.05 LICENSEE shall have no obligation to pay royalties under this
Agreement on PRODUCTS which LICENSEE has purchased from another licensee who has
already paid royalties on such PRODUCTS to LICENSOR under the PATENT RIGHTS,
provided that the rights granted to LICENSEE with the purchase of such PRODUCTS
shall not exceed those which the other licensee is entitled to extend to its
customers.

     5.01 This Agreement shall remain  in effect until the expiration of the
last patent to expire under the PATENT RIGHTS, unless terminated earlier as
provided in this Agreement.

LICENSEE's intention to terminate.

     5.03 LICENSOR, at its discretion, may terminate this Agreement for one of
the following reasons by giving notice to LICENSEE.

     (1) If there is a sale, loss, transfer, or other disposition by LICENSEE of
         or execution or other legal process levied upon or enforced against all
         or a substantial portion of the assets of LICENSEE, or an action or
         proceeding is commenced by or against LICENSEE under any bankruptcy act
         or under any present or future law for the relief of debtors, or a
         receiver or trustee is appointed for LICENSEE or LICENSEE's assets, or
         an action or proceeding is commenced to dissolve LICENSEE, or LICENSEE
         makes an assignment for the benefit of creditors or ceases to carry on
         business for any reason; or

     (2) If LICENSEE fails to perform or observe any agreement, provision, duty
         or obligation under this Agreement, such as the


                                      -4-
<PAGE>   6
          timely reporting and payment of royalties, and does not remedy the
          failure within thirty (30) days after receipt of notice from LICENSOR,
          provided, however, that repeated failures by LICENSEE shall constitute
          and independent basis for LICENSOR to terminate this Agreement.

     5.04 The termination of this Agreement shall not prejudice any rights or
remedies which shall have accrued to either party prior to the date of such
termination.

or any Parent or Subsidiary to render consulting or advisory services and is
compensated for such services, and any director of the Company whether

the employment or consulting relationship with the Company or any Parent or
Subsidiary is not interrupted or terminated. Continuous Status as an Employee or

other personal leave; provided, however, that for purposes of Incentive Stock

amended.

                (n) "Fair Market Value" means, as of any date, the value of

or;

                        (iii) In the absence of an established market for the

                                      -4-
<PAGE>   5

increase the size of the Committee and appoint additional members thereof,

the Plan shall be administered by (A) the Board or (B) a committee designated by
the Board, which committee shall be constituted in such a manner as to satisfy
the legal requirements relating to the administration of incentive stock option
plans, if any, of California corporate and securities laws, of the Code, and of
any applicable stock exchange (the "Applicable Laws"). Once appointed, such
Committee shall continue to serve in its designated capacity until otherwise
directed by the Board. From time to time the Board may increase the size of the
Committee and appoint additional members thereof, remove members (with or
without cause) and appoint new members in substitution therefor, fill vacancies,
however caused, and remove all members of the Committee and thereafter directly
administer the Plan, all to the extent permitted by the Applicable Laws.

                (c) Powers of the Administrator. Subject to the provisions of
the Plan and, in the case of a Committee, the specific duties delegated by the
Board to such Committee, and subject to the approval of any relevant
authorities, including the approval, if required, of any stock exchange upon
which the Common Stock is listed, the Administrator shall have the authority, in
its discretion:

                        (i) to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(k) of the Plan;

                        (ii) to select the Consultants and Employees to whom
Options and Stock Purchase Rights may from time to time be granted hereunder;

                        (iii) to determine whether and to what extent Options
and Stock Purchase Rights or any combination thereof are granted hereunder;

                        (iv) to determine the number of shares of Common Stock
to be covered by each such award granted hereunder;

                        (v)to approve forms of agreement for use under the Plan;

                        (vi) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder;

                        (vii) to determine whether and under what circumstances
an Option may be settled in cash under subSection 9(f) instead of Common Stock;



                                      -5-
<PAGE>   6

                        (viii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was
granted;

                        (ix) to determine the terms and restrictions applicable
to Stock Purchase Rights and the Restricted Stock purchased by exercising such
Stock Purchase Rights; and

                        (x) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

                (d) Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options or Stock Purchase
Rights.

        5. Eligibility.

                (a) Nonstatutory Stock Options and Stock Purchase Rights may be
granted to Employees and Consultants. Incentive Stock Options may be granted
only to Employees. An Employee or Consultant who has been granted an Option or
Stock Purchase Right may, if otherwise eligible, be granted additional Options
or Stock Purchase Rights.

                (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value:

                        (i) of Shares subject to an Optionee's Incentive Stock
Options granted by the Company, any Parent or Subsidiary, which

                        (ii) become exercisable for the first time during any
calendar year (under all plans of the Company or any Parent or Subsidiary)
exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock
Options. For purposes of this Section 5(b), Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

                (c) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment relationship with the Company, nor shall
it interfere in any way with his or her right or the Company's right to
terminate his or her employment relationship at any time, with or without cause.

                (d) Upon the Company or a successor corporation issuing any
class of common equity securities required to be registered under Section 12 of
the Exchange Act or upon the Plan being assumed by a corporation having a class
of common equity securities required to be registered under Section 12 of the
Exchange Act, the following limitations shall apply to grants of Options and
Stock Purchase Rights to Employees:



                                      -6-
<PAGE>   7

                        (i) The foregoing limitation shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 12(a).

                        (ii) If an Option or Stock Purchase Right is cancelled
(other than in connection with a transaction described in Section 12), the
cancelled Option or Stock Purchase Right will be counted against the limit set
forth in Section 5(e)(i). For this purpose, if the exercise price of an Option
or Stock Purchase Right is reduced, the transaction will be treated as a
cancellation of the Option or Stock Purchase Right and the grant of a new Option
or Stock Purchase Right.

        6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company, as described in Section 18 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 14 of the Plan.

        7. Term of Option. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. However, in the case of an Incentive
Stock Option granted to an Optionee who, at the time the Option is granted, owns
stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.

        8. Option Exercise Price and Consideration.

                (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Board, but shall be subject to the following:

                        (i) In the case of an Incentive Stock Option

                                (A) granted to an Employee who, at the time of
the grant of such Incentive Stock Option, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant.

                                (B) granted to any Employee other than an
Employee described in the preceding paragraph, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.

                        (ii) In the case of a Nonstatutory Stock Option

                                (A) granted to a person who, at the time of the
grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of the grant.

                                (B) granted to any person, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on
the date of grant.



                                      -7-
<PAGE>   8

                (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing methods of payment. In
making its determination as to the type of consideration to accept, the Board
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

        9. Exercise of Option.

                (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Board, including performance criteria with respect to the
Company and/or the Optionee, and as shall be permissible under the terms of the
Plan. In no event shall the Option be exercised at a rate of less than 20% per
year over five years from the date of grant of the Option.

                        An Option may not be exercised for a fraction of a
Share.

                        An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 8(b) of the
Plan. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 12 of the Plan.

                        Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                (b) Termination of Employment or Consulting Relationship. In the
event of termination of an Optionee's Continuous Status as an Employee or
Consultant with the Company (but not in the event of an Optionee's change of
status from Employee to Consultant (in which case an Employee's Incentive Stock
Option shall automatically convert to a Nonstatutory Stock Option on the
ninety-first (91st) day following such change of status) or from Consultant to
Employee), such



                                      -8-
<PAGE>   9

Optionee may, but only within such period of time as is determined by the
Administrator, of at least thirty (30) days, with such determination in the case
of an Incentive Stock Option not exceeding three (3) months after the date of
such termination (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise his or her Option to
the extent that Optionee was entitled to exercise it at the date of such
termination. To the extent that Optionee was not entitled to exercise the Option
at the date of such termination, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate.

                (c) Disability of Optionee. In the event of termination of an
Optionee's consulting relationship or Continuous Status as an Employee as a
result of his or her disability, Optionee may, but only within six (6) months
from the date of such termination (and in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), exercise
the Option to the extent otherwise entitled to exercise it at the date of such
termination; provided, however, that if such disability is not a "disability" as
such term is defined in Section 22(e)(3) of the Code, in the case of an
Incentive Stock Option such Incentive Stock Option shall automatically convert
to a Nonstatutory Stock Option on the day three months and one day following
such termination. To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
to the extent so entitled within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                (d) Death of Optionee. In the event of the death of an Optionee,
the Option may be exercised at any time within twelve (12) months following the
date of death (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent that the Optionee was entitled to exercise the Option at
the date of death. If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If, after death, the
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

                (e) Rule 16b-3. Options granted to persons subject to Section
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

                (f) Buyout Provisions. The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.



                                      -9-
<PAGE>   10

        10. Non-Transferability of Options and Stock Purchase Rights. Options
and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

        11. Stock Purchase Rights.

                (a) Rights to Purchase. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing of the terms, conditions and restrictions related
to the offer, including the number of Shares that such person shall be entitled
to purchase, the price to be paid, and the time within which such person must
accept such offer, which shall in no event exceed thirty (30) days from the date
upon which the Administrator made the determination to grant the Stock Purchase
Right. The offer shall be accepted by execution of a Restricted Stock purchase
agreement in the form determined by the Administrator. Shares purchased pursuant
to the grant of a Stock Purchase Right shall be referred to herein as
"Restricted Stock."

                (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock purchase agreement shall grant the Company a
repurchase option exercisable within 90 days of the voluntary or involuntary
termination of the purchaser's employment with the Company for any reason
(including death or Disability). The purchase price for Shares repurchased
pursuant to the Restricted Stock purchase agreement shall be the original price
paid by the purchaser and may be paid by cancellation of any indebtedness of the
purchaser to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine, but at a minimum rate of 20% per year.

                (c) Other Provisions. The Restricted Stock purchase agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion. In
addition, the provisions of Restricted Stock purchase agreements need not be the
same with respect to each purchaser.

                (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 12
of the Plan.

        12. Adjustments Upon Changes in Capitalization or Merger.

                (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding



                                      -10-
<PAGE>   11

Option or Stock Purchase Right, 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 issued 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 issuance 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 an Option or Stock
Purchase Right.

                (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action. To the extent it has
not been previously exercised, the Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

                (c) Merger. Subject to subsection (d) below, in the event of a
merger of the Company with or into another corporation, the Option or Stock
Purchase Right shall be assumed or an equivalent option or right shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation. If, in such event, the Option or Stock Purchase Right is
not assumed or substituted, the Option or Stock Purchase Right shall terminate
as of the date of the closing of the merger. For the purposes of this paragraph,
the Option or Stock Purchase Right shall be considered assumed if, following the
merger, the option or right confers the right to purchase, for each Share of
Optioned Stock subject to the Option or Stock Purchase Right immediately prior
to the merger, the consideration (whether stock, cash, or other securities or
property) received in the merger by holders of Common Stock for each Share held
on the effective date of the transaction (and if holders were offered a choice
of consideration, the type of consideration chosen by the holders of a majority
of the outstanding Shares); provided, however, that if such consideration
received in the merger was not solely common stock of the successor corporation
or its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of
the Option or Stock Purchase Right, for each Share of Optioned Stock subject to
the Option or Stock Purchase Right, to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger.

                (d) Change of Control. In the event of (a) A Constructive
Termination or (b) Optionee's termination by the Company without Cause, within
twelve (12) months following a Change of Control, all outstanding options shall
become fully vested and exercisable.



                                      -11-
<PAGE>   12

        13. Time of Granting Options and Stock Purchase Rights. The date of
grant of an Option or Stock Purchase Right shall, for all purposes, be the date
on which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Board. Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

        14. Amendment and Termination of the Plan.

                (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or discontinue the Plan, but no amendment, alteration, suspension
or discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent. In addition, to
the extent necessary and desirable to comply with Rule 16b-3 under the Exchange
Act or with Section 422 of the Code (or any other applicable law or regulation,
including the requirements of the NASD or an established stock exchange), the
Company shall obtain shareholder approval of any Plan amendment in such a manner
and to such a degree as required.

                (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options or Stock Purchase Rights
already granted, and such Options and Stock Purchase Rights shall remain in full
force and effect as if this Plan had not been amended or terminated, unless
mutually agreed otherwise between the Optionee and the Board, which agreement
must be in writing and signed by the Optionee and the Company.

        15. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option or Stock Purchase Right unless the
exercise of such Option or Stock Purchase Right and the issuance and delivery of
such Shares pursuant thereto shall comply with all relevant provisions of law,
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, 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.

                As a condition to the exercise of an Option or Stock Purchase
Right, the Company may require the person exercising such Option or Stock
Purchase Right to represent and warrant at the time of any such exercise that
the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
relevant provisions of law.

        16. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

                The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

        17. Agreements. Options and Stock Purchase Rights shall be evidenced by
written agreements in such form as the Board shall approve from time to time.

        18. Shareholder Approval. Continuance of the Plan shall be subject to
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such shareholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any stock exchange upon which the Common Stock is listed.

        19. Information to Optionees and Purchasers. The Company shall provide
to each Optionee and to each individual who acquired Shares pursuant to the
Plan, not less frequently than annually during the period such Optionee or
purchaser has one or more Options or Stock Purchase Rights outstanding, and, in
the case of an individual who acquired Shares pursuant to the Plan, during the
period such individual owns such Shares, copies of annual financial statements.
The Company shall not be required to provide such statements to key employees
whose duties in connection with the Company assure their access to equivalent
information.
