                         [LOGO OF ISONICS CORPORATION]
   
  This Prospectus relates to the offering by Isonics Corporation, a California
corporation ("Isonics" or the "Company"), of 850,000 shares (the "Shares") of
common stock, no par value (the "Common Stock"), and 850,000 redeemable common
stock purchase warrants (the "Warrants") initially as units ("Units"), each
Unit consisting of one share of Common Stock and one Warrant. The Shares and
the Warrants are sometimes referred to collectively as the "Securities." All of
the Securities offered hereby are being sold by the Company. Until the
completion of this offering, the Shares and Warrants may only be purchased
together as Units on the basis of one Share and one Warrant, but will trade
separately immediately upon the closing of the offering. Each Warrant initially
entitles the holder thereof to purchase one share of Common Stock at a price of
$     per share, which is 150% of the initial public offering price per Share
offered hereby, subject to adjustment under certain circumstances. The Warrants
are exercisable at any time, unless previously redeemed, from the date of this
Prospectus through the fifth anniversary of the date of this Prospectus,
subject to certain conditions. The Company may redeem the Warrants, in whole or
in part, at any time upon at least 30 days prior written notice to the
registered holders thereof, at a price of $0.05 per Warrant, if the closing
price of the Common Stock as reported on the Nasdaq SmallCap Market equals or
exceeds 200% of the initial public offering price per Share for at least 20
consecutive trading days ending immediately before the notice of redemption.
       
  Prior to this offering, there has been no public market for the Securities,
Common Stock or Warrants, and there is no assurance that such a market will
develop or be maintained following the offering. After completion of this
offering, there will no public market for the Securities as units. It is
currently estimated that the initial public offering price will be between
$5.90 and $7.90 per Share and $0.10 per Warrant. See "Underwriting" for the
factors considered in determining the pubic offering price. The Company has
applied for listing of the Common Stock and Warrants on the Nasdaq SmallCap
Market ("Nasdaq SCM") under the symbols "ISNX" and "ISNXW," respectively, and
has also applied for listing of the Common Stock and Warrants on the Boston
Stock Exchange.     
   
  THE SECURITIES OFFERED HEREBY ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF
RISK, IMMEDIATE AND SUBSTANTIAL DILUTION AND RESTRICTIONS ON SECONDARY TRADING
IN SOME STATES FOR A PERIOD OF TIME AFTER THIS OFFERING. SEE "RISK FACTORS"

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and financial statements and notes thereto appearing elsewhere in
this Prospectus. The Securities offered hereby involve a high degree of risk.
See "Risk Factors." Except where otherwise indicated, all share and per share
data in this Prospectus (including data with respect to options and warrants to
purchase shares) have been adjusted to reflect (i) a 1-for-6.89 reverse split
of the outstanding Common Stock, and (ii) the conversion into Common Stock of
all outstanding shares of preferred stock of the Company, which will occur
before the closing of this offering. See "Description of Capital Stock." In
addition, unless otherwise indicated, all information in this Prospectus
assumes that the Underwriters' over-allotment option will not be exercised.
 
                                  THE COMPANY
 
  Isonics is an advanced materials and technology company which develops and
commercializes products based on enriched stable isotopes and high purity
materials. Stable isotopes can be thought of as ultra-ultra pure materials.
This high degree of purification accomplished on the sub-atomic level provides
enhanced performance properties compared to normal purity materials. Stable
isotopes have commercial uses in several areas, including energy; medical,
research, diagnostics and drug development; product tagging and stewardship;
semiconductors; and optical materials. Isonics has successfully developed and
commercialized two stable isotope products and intends to promote the emergence
and growth of new stable isotope applications.
 
  The Company's principal product to date is isotopically depleted zinc ("DZ").
DZ, in different chemical forms, is used to prevent corrosion in nuclear power
plants. Corrosion is a cause of high radiation fields in such plants which can
result in radiation exposure to workers. DZ also reduces environmental cracking
in certain kinds of nuclear reactors which, if not controlled, can require
extremely costly repairs or can result in premature shutdown and de-
commissioning of the facility. The Company believes that it provides
substantially all of the DZ used in nuclear power plants worldwide.
   
  The application of DZ was developed by General Electric Company ("GE"), where
the founders of the Company were previously employed. Before May 1996, all
sales of DZ by the Company were made to GE pursuant to sales orders, which in
turn resold the product to end users. In addition to sales to GE, in May 1996
Isonics commenced direct sales to end users, and for the three months ended
July 31, 1996, approximately 10% of net revenues were from sales made directly
to end users. The amount of future direct sales of DZ to certain end user
customers may be limited by, among other things, certain rights or agreements
of GE, and future direct sales could also be affected by GE's future intentions
regarding sales or purchases of DZ independently of the Company, see "Risk
Factors--Number of DZ Customers."     
 
  New applications for stable isotopes are continually being developed by the
Company and by third parties. The Company believes that many new applications
have the potential to create new markets. One opportunity is to supply stable
isotope labeled compounds for the diagnostic breath test ("DBT") market. DBTs
provide early diagnosis of conditions that could otherwise lead to expensive
procedures such as endoscopies and biopsies. DBTs under development by third
parties which utilize stable isotopes in their application include tests to
diagnose peptic ulcers, fat malabsorption and liver function. A urea DBT
relating to peptic ulcers has recently been approved by the U.S. Food and Drug
Administration (the "FDA"), and the Company believes that other companies have
applied to the FDA or comparable agencies in foreign countries for approval of
these tests, which must be obtained before any products can be sold. Certain
DBTs are currently marketed in certain European countries.
 
  The Company holds an option, subject to satisfaction of certain conditions,
to acquire an exclusive license to two Yale University patents which cover
semiconductor devices made of isotopically pure silicon, germanium, gallium
arsenide and most isotopically pure compound semiconductors. The patents claim
that isotopic purity provides improved device speed and improved thermal
conductivity, two properties which are of great importance to the semiconductor
industry. According to the Semiconductor Industry Association, sales in 1995 of
silicon wafers and other semiconductor substrates were approximately $6
billion. The Company is collaborating with Yale to evaluate these isotopically
engineered semiconductor applications. The Company believes that if evaluations
demonstrate the commercial feasibility of one or more products, demand could
emerge in certain segments of the semiconductor market. There can be no
assurance, however, that these evaluations will demonstrate the commercial
feasibility of any products, that the Company will be able to commercialize any
such products or that a market will emerge for any such products.
   
  The Company was formed in March 1992 and incorporated in California in March
1993 under the name A&R Materials, Inc. In October 1996, the Company changed
its name to Isonics Corporation. The Company's principal executive offices are
located at 4010 Moorpark Avenue, Suite 119, San Jose, California, 95117. Its
telephone number is (408) 260-0155.

                                 RISK FACTORS
 
  An investment in the Securities offered hereby involves a high degree of
risk. In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
Securities offered hereby. This Prospectus contains forward-looking statements
that involve risks and uncertainties. The Company's actual results could
differ materially from the results discussed in the forward-looking
statements. Factors that could cause or contribute to such differences include
those discussed below and elsewhere in the Prospectus.
   
  Relationship With Certain Suppliers and Raw Materials. The Company depends
upon a single processor, located in Russia, for one process involved in the
manufacturing of its products, and upon a single supplier or a limited number
of suppliers and processors for certain other manufacturing processes.
Although the Company does have written agreements with certain of its
suppliers and processors, the Company does not have any written agreements
with other suppliers and processors. Although the Company seeks to reduce its
dependence on its sole and limited suppliers, disruption or termination of any
of the sources could occur, and such disruptions could have at least a
temporary material adverse effect on the Company's business, financial
condition and results of operations. Moreover, a prolonged inability to obtain
alternative sources for processing could materially adversely affect the
Company's relations with its customers. See "Risk Factors--Expansion of the
Company's Product Offerings" and "Business--Manufacturing and Supply."     
   
  Operations in Russia. The processing of the Company's products is dependent
upon an isotope enrichment plant, located in Russia, which is owned by the
Ministry of Atomic Energy of the Russian Federation. The Company recently
signed an agreement under which the Ministry of Atomic Energy has agreed to
supply the Company with zinc, cadmium, silicon, and carbon isotopes over the
next three years. Under the agreement, the Company negotiates with the plant
management annually regarding the price and certain other terms of the
products to be supplied in the upcoming year, and the next such negotiation is
expected to occur in November 1996. If such an agreement is entered into, the
agreement is expected to provide, among other things, that the plant will
exclusively supply the Company and that any disputes arising under the
agreement will be resolved by arbitration conducted in Europe under
international commercial arbitration rules. Even if such an agreement is
negotiated, the enforceability of such an agreement might be subject to a
greater degree of uncertainty than if the agreement was with a U.S. company
and disputes were resolved in the United States. The plant is generally
subject to the same government laws, policies, controls and regulations as
apply to private enterprises in Russia. To date, these laws, policies,
controls and regulations have not had any material adverse effect on the
Company's business or relations with the plant, although there can be no
assurance that this will be the case in the future. Operations in Russia
entail certain risks. In recent years, the former republics of the Soviet
Union have experienced political, social and economic change as constituent
republics sought independence from the former central government in Moscow,
and certain of the republics including Russia have attempted to transition
from a centrally controlled economy toward market-based economies. These
changes have involved, in certain cases, armed conflict in certain republics.
There can be no assurance that political or economic instability in these
republics will not continue or worsen. The supply of stable isotopes could be
directly affected by political, economic and military conditions in Russia.
Accordingly, the operations of the Company could be materially adversely
affected if hostilities in Russia should occur, if trade between Russia and
the United States were interrupted or curtailed, if political conditions in
Russia disrupt transportation or processing concerning the Company's goods, if
laws or governmental policies concerning foreign ownership or business
operations in Russia change substantially, or if tariffs are introduced or
freight rates change significantly. There can also be no assurance that the
Company's relationship with the processing plant in Russia will be
successfully maintained, even apart from these political, economic or military
factors. In addition, there have been certain privatization programs in
certain countries of the former Soviet Union, although the Company is not
aware of any current proposals to privatize the plant or other government-
controlled isotope production facilities in Russia. If at some future date the
plant was privatized, the Company cannot predict whether any such
privatization would result in a favorable or an unfavorable impact on the
Company. Disruption or termination of the Company's supply     
 
                                       5
<PAGE>
 
   
sources could have a material adverse effect on the Company's business,
financial condition and results of operations. The Company does not maintain
political risk insurance. Additionally, Russian courts lack experience in
commercial dispute resolution, and many of the procedural remedies for
enforcement found in western jurisdictions are not available in Russia.
Difficulties may be encountered in enforcing judgments of foreign courts or of
arbitrators, in the case of the Company's agreements with suppliers or
processors, or in otherwise protecting the Company's rights with its Russian
suppliers and transporters. There can be no assurance that this difficulty in
enforcing the rights will not have a material adverse effect on the Company.
See "Business--Manufacturing and Supply."     
   
  Customer Concentration. Historically, substantially all of the Company's net
revenues in any particular period have been attributable to a limited number
of customers. Net revenues from GE accounted for 66%, 59% and 88% of net
revenues for the three months ended July 31, 1996, and the years ended April
30, 1995 and 1996, respectively. One other customer accounted for 20% of net
revenues for the three months ended July 31, 1996. A second customer accounted
for 10% of net revenues for the three months ended July 31, 1996. A third
customer accounted for 11% of net revenues for the years ended April 30, 1995
and 1996. A fourth customer accounted for 26% of net revenues for the year
ended April 30, 1995. The Company expects that if it continues to increase
sales of depleted zinc products to end users and if it develops and sells
products in the medical and research and electronic materials industries,
concentration of net revenues from a limited number of customers will be
reduced. None of the Company's customers have entered into long-term
agreements to purchase the Company's products. In particular, the Company's
sales of DZ to GE have been pursuant to sales orders placed from time to time
by GE, and the Company does not have any written purchase or sales agreements
with GE relating to sales of DZ or other products. If completed sales orders
are not replaced on a timely basis by new orders from customers, the Company's
net revenues could be materially and adversely affected. The Company's net
revenues also could be adversely affected by a number of factors including the
loss of a significant customer, reductions in orders from any significant
customer compared to historical buying levels or otherwise, or the
cancellation of a significant order from a customer. Any of these factors,
many of which are outside the Company's control, could have a material adverse
effect on the Company's business, financial condition and results of
operations.     
   
  Limited Operating History; History of Operating Losses. The Company was
incorporated in March 1993 and has had only a limited operating history upon
which evaluation of its prospects can be made. The Company had net losses of
$171,000 and $143,000, respectively, for the years ended April 30, 1994 and
1995, and had net income of $281,000 and $43,000 for the fiscal year ended
April 30, 1996 and the three months ended July 31, 1996, respectively. At July
31, 1996, the Company had negative working capital of $134,000 and retained
earnings of $10,000. In addition, the Company expects that it will incur a net
loss for the fiscal year ended July 31, 1997, largely as a result of expected
significant increases in expenses associated with anticipated growth in
research and development, marketing and sales efforts and capital
expenditures, and an extraordinary charge relating to payment of the Placement
Notes upon completion of this offering. The Company's limited operating
history makes the prediction of future operating results difficult. The
Company does not believe that prior growth rates are necessarily indicative of
future operating results. Future operating results will depend on many
factors, including demand for the Company's products, the level of product and
price competition, the ability of the Company to develop and market new
products, the Company's ability to control costs, general economic conditions
and other factors. There can be no assurance that the Company will achieve or
sustain profitability. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."     
   
  Factors Affecting Operating Results; Fluctuations in Quarterly Results. The
Company's operating results could be materially adversely affected by a number
of factors, including failure of its suppliers to process a sufficient volume
of products in a timely manner; introduction of new products by competitors;
adequacy of the Company's suppliers manufacturing capacity; changes in pricing
policies of the Company, its customers, competitors or suppliers; economic
conditions in the markets that the Company serves; the need to increase
expenditures for research and development; failure to introduce new or
improved products on a timely basis; and the rescheduling or cancellation of
orders by its customers. The Company's quarterly operating results have varied
in the past and may in the future vary significantly, depending on factors
such as the size and timing of customer orders, pricing and other competitive
conditions and the timing of new product announcements and     
 
                                       6
<PAGE>
 
   
releases by the Company and its competitors. The Company operates with little
order backlog. Moreover, a significant portion of the Company's total revenues
have been, and the Company believes will continue to be, derived from a
limited number of orders in any particular quarter, and the timing of such
orders and their fulfillment has caused, and is likely to continue to cause,
material fluctuations in the Company's operating results, particularly on a
quarterly basis. As a result, a lost or delayed sale could have a significant
impact on the Company's operating results for a particular period. It is
likely that in some future quarter, the Company's operating results will be
below the expectations of public market analysts and investors. In such event,
the price of the Common Stock and Warrants would likely be materially
adversely affected. In addition, as a result of repayment of certain Placement
Notes issued in a recent private placement transaction, the Company is likely
to record an extraordinary charge to operations for the quarter in which the
offering is completed, and as a result the Company expects to have a
significant net loss for the quarter in which the offering occurs. See
"Capitalization--Recent Financing Transactions."     
   
  Number of DZ Customers. Patents have been granted to GE with respect to a
method for inhibiting deposition of radioactive cobalt in a water-cooled
nuclear reactor through the use of DZ. The nuclear power facilities that have
purchased DZ to date directly from the Company have received correspondence
from GE indicating that such customers may practice the method of utilizing DZ
in such facilities and may purchase DZ from entities other than GE, such as
the Company. In addition, certain nuclear power facilities are located in
countries where GE does not have similar patents. Similarly, certain third
party entities other than nuclear power plants, such as certain entities that
construct nuclear power facilities or equipment, have licenses from GE which
the Company believes may allow them to purchase DZ from the Company. Other
facilities or third party entities may not be granted such licenses, and the
Company's ability to sell DZ to such customers may be limited by applicable
patent law and/or such customers' agreements with GE. GE may in the future
grant licenses to additional end users entitling them to purchase DZ from
third parties such as the Company, and GE may continue to purchase DZ directly
from the Company, although there can be no assurance that this will be the
case. GE could, among other actions, seek alternative sources of DZ to compete
with the Company and seek to sell or purchase DZ independently of the Company.
Nevertheless, it is possible that the Company's sales of DZ may be limited to
only those entities described above that can purchase DZ from the Company
without infringing on GE's intellectual property rights.     
 
  Future Additional Capital Requirements. The Company's capital requirements
will depend on numerous factors, including the level of future capital
expenditures, the level of resources devoted to research and development and
marketing of its products, market acceptance and demand for its products, and
other factors. The Company believes the net proceeds of this offering,
together with cash on hand and cash expected to be generated from operations,
will provide adequate funding for the Company's anticipated operations for at
least the next twelve months. Nevertheless, the Company may be required to
raise additional funds through public or private debt or equity financings,
collaborative relationships, bank facilities or other arrangements. There can
be no assurance that the Company will not require additional funding sooner
than expected or that such additional funding, if needed, will be available on
terms attractive to the Company, if at all. Any additional equity financing
may be dilutive to shareholders, and debt financing, if available, may involve
restrictive covenants. See "--Expansion of the Company's Product Offerings,"
"Use of Proceeds," and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
  Competition. The markets for the Company's products are highly competitive,
and the Company expects that competition will continue and increase as markets
grow and new opportunities are realized. Some of the Company's current
competitors, and many of the Company's potential competitors, have
significantly greater financial, marketing, product development, testing and
other resources than the Company. As a result, they may have the capacity to
respond more quickly to changes in customer requirements or to devote greater
resources to the development, testing, marketing and sale of their products
than the Company. Some of the Company's competitors may form partnerships or
alliances with larger companies, with the resulting entity possessing more
market strength than the Company. New competitors will likely emerge, and some
new competitors may gain significant market share. There can be no assurance
that the Company will be able to compete successfully against current and
future competitors, or that competitive pressures will not have a material
adverse effect on
 
                                       7
<PAGE>
 
the Company's business, operating results and financial condition. See
"Business--Competition." Increased competition could result in price
reductions, reduced transaction size, fewer customer orders and reduced gross
margins, any of which could have a material adverse effect on the Company's
business, operating results and financial condition.
 
  The Company's competition varies greatly depending on which product or
industry is considered. At present, the Company believes it supplies
substantially all of the DZ used in nuclear power plants worldwide, but
believes that other entities or persons may begin producing DZ. Several such
possible producers have adequate technical and financial resources to become
viable competitors of the Company in the near future. In particular, GE, which
to date has been the Company's largest customer, has indicated that it may
seek to sell DZ to end users independently of the Company or may seek
alternative sources of DZ other than the Company. The Company has several
larger and numerous smaller competitors in the area of stable isotope labeled
compounds and supplying materials for diagnostic breath test products. Due to
the early stage of the electronic and optical materials opportunities, the
Company has not identified material competitors in these markets. However, if
viable commercial markets emerge for such products, the Company anticipates
that substantial competition will emerge.
 
  Expansion of the Company's Product Offerings. The Company's future success
will depend in part on its ability to enhance its current product offerings on
a timely basis. The expansion of the Company into new products and processes
will require significant future capital commitments. Substantial development
work must be undertaken before such products are ready for commercial
introduction. There can be no assurance that the Company will successfully
develop new products or that it will be able to improve or expand its initial
products to keep pace with the demands of the marketplace. Moreover, there can
be no assurance that commercial markets will emerge for the potential products
that the Company is developing and considering developing. In addition, other
products or technologies currently exist, and will be developed in the future,
that compete directly with the Company's current products and products that
the Company may develop in the future.
 
  The Company has entered into an agreement with Yale University through which
the Company has the right, subject to satisfaction of certain conditions, to
acquire an exclusive license for two U.S. patents entitled Isotopically
Enriched Semiconductor Devices. The Company's right to exercise its option is
dependent upon the attainment of certain milestones, which the Company
believes it will achieve before expiration of the option term in March 1997.
There can be no assurance, however, that the Company will satisfy the
conditions to allow it to exercise the option or will enter into a license
agreement with Yale University. If the Company did not satisfy such conditions
before March 1997 and Yale did not agree to extend the option period, the
Company could lose its ability to acquire rights to the technology underlying
the potential isotopically pure semiconductor products described in the
Prospectus. See "Business--Products--Isotopically Pure Semiconductors."
 
  Dependence on Key Personnel. The Company's future success will depend in
significant part upon the continued service of its key technical, sales and
senior management personnel, including James E. Alexander, the Company's
President and Chief Executive Officer, and Boris Rubizhevsky, the Company's
Senior Vice President, Isotope Production and Supply. The Company maintains $1
million of key man life insurance on the lives of Messrs. Alexander and
Rubizhevsky. The loss of the services of one or more of the Company's
executive officers or other key technical personnel could have a material
adverse effect on the Company's business, financial condition or results of
operations. In addition, the Company's future operating results depend, in
part, upon its ability to attract and retain qualified personnel for its
operations. The failure to attract or retain such persons could materially
adversely affect the Company's business, financial condition and results of
operations.
 
  Reliance on Strategic Collaborations and Relationships. The Company's
strategy for the development, processing and marketing of certain of its
products includes entering into various collaborations with corporate
partners, processors, suppliers and others. The Company has developed
strategic relationships, including cooperative research and development
projects, with certain third parties. There can be no assurance that existing
collaborative arrangements will continue, or that the Company will be able to
negotiate other successful collaborative arrangements in the future. The loss
of any of these relationships could adversely affect the Company's business,
financial condition and results of operations. If the Company is not able to
maintain or
 
                                       8
<PAGE>
 
establish such arrangements, it would likely face increased capital
requirements to undertake such activities at its own expense, and could also
encounter significant delays in development, processing, marketing or sale of
products into certain markets. See "Business--Manufacturing and Supply."
 
  Third Party Reimbursement of Healthcare Costs. Some of the Company's
potential products, such as DBT products, are expected to compete in the
medical diagnostics and healthcare markets. Demand for such products, and the
prices at which such products can be sold, may depend in large part upon the
extent to which purchasers will be reimbursed by governmental agencies and
insurance companies for use of such products. Future federal or state
legislation could result in a substantial restructuring of the healthcare
delivery system. While the Company cannot predict whether any legislative or
regulatory proposals will be adopted or the effect such proposals may have on
its business, uncertainty regarding such proposals, as well as the adoption of
such proposals, could have a material adverse effect on the Company's ability
to develop and sell products that compete in these markets. Such reforms, if
adopted, and ongoing changes in the healthcare industry, could adversely
affect the pricing of therapeutic or diagnostic products in the United States
or the amount of reimbursement available from governmental agencies or third
party insurers, and consequently could have a material adverse effect on the
Company. In both domestic and foreign markets, sales of such products, if any,
will depend in part on the availability of reimbursement from third party
payers, such as government and private insurance plans and other
organizations.
 
  Product and Other Liability; Minimal Insurance Coverage. The Company's
business exposes it to potentially substantial product, environmental,
occupational and other liability risks which are inherent in research and
development, preclinical study, clinical trials, manufacturing, marketing,
distribution and use, of the Company's current and potential products,
including, but not limited to, products for pharmaceutical, medical device and
nuclear energy markets. The Company currently does not have product liability
insurance, but may seek such coverage as it deems prudent in light of future
operations. There can be no assurance that insurance coverage will be
available at an acceptable cost, if at all, or that a product liability or
other claim would not materially and adversely affect the business, financial
condition and results of operations of the Company even if such insurance was
obtained.
 
  Management of Growth. The Company has experienced a period of rapid growth
and expansion, which has placed and continues to place, a significant strain
on its resources. To accommodate this growth, the Company will be required to
implement a variety of new and upgraded operational and financial systems,
procedures and controls, including the improvement of its other internal
management systems. There can be no assurance that such efforts can be
accomplished successfully. In addition, this growth, as well as the Company's
market diversification and product development activities, will necessitate an
increase in the number of the Company's employees. During fiscal 1997, the
Company added a General Manager of Diagnostics and a Chief Financial Officer
as well as other support personnel. If the Company sustains its growth in the
future, the Company will need to continue to implement and improve its
operational and management information systems and to hire, train, motivate
and manage its employees. The Company's ability to successfully assimilate new
operations and new personnel involved with any future expansion will have a
material effect on the Company's future business, financial condition and
results of operations. There can be no assurance that the Company will be able
to manage these changes successfully or that the Company's systems, procedures
and controls will be adequate to support the Company's operations. Any failure
to improve the Company's operational and management systems or to hire, train,
motivate or manage employees could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
  No Prior Market; Stock Price Volatility. Prior to this offering, there has
been no public market for the Company's securities. Consequently, the initial
public offering price will be determined by negotiations among the Company and
the Representatives of the Underwriters. There can be no assurance that an
active public market for the Common Stock and Warrants will develop or be
sustained after the offering or that the market price of the Common Stock and
Warrants will not decline below the initial public offering price. The trading
price of the Company's securities could be subject to wide fluctuations in
response to quarter to quarter variations in operating results, announcements
of technological innovations or new products by the Company or its
 
                                       9
<PAGE>
 
competitors, changes in earnings estimates by analysts, or other events or
factors. In addition, the stock market has experienced wide price and volume
fluctuations, which have at times been unrelated to the operating performance
of the companies whose securities are traded. These broad market fluctuations
may adversely affect the market price of the Common Stock and Warrants.
 
  Representatives' Warrants. At the consummation of this offering, the Company
will sell to the Representatives for nominal consideration the
Representatives' Warrants to purchase up to 85,000 shares of Common Stock and
85,000 Warrants, representing 10% of the Shares and 10% of the Warrants,
respectively, offered hereby. The Representatives' Warrants will be
exercisable for a period of five years after the date of this Prospectus. Each
Representatives' Warrant will entitle the holder to purchase one share of
Common Stock at a price of $   per share, which is 120% of the initial public
offering price of the Shares (the initial public offering price of the Shares
referred to as the "IPO Price Per Share"), and, upon payment of $   , which is
120% of the initial public offering price of the Warrants, to acquire one
Warrant at an exercise price equal to 150% of the IPO Price Per Share. As long
as the Representatives' Warrants or other outstanding warrants remain
unexercised, the Company's ability to obtain additional capital might be
adversely affected. Moreover, the Representatives and other holders of
outstanding warrants may be expected to exercise such warrants at a time when
the Company would, in all likelihood, be able to obtain needed capital by a
new offering of its securities on terms more favorable than those provided by
the warrants. Holders of the Representatives' Warrants and holders of other
warrants have certain registration rights with respect to shares of Common
Stock underlying those warrants.
 
  Protection of Intellectual Property. The Company does not currently hold any
patents, and has not filed any patent applications, regarding DZ or its other
actual or potential products. The Company relies primarily on a combination of
trade secrets, confidentiality procedures and contractual provisions to
protect its technology. Despite the Company's efforts, unauthorized parties
may attempt to obtain and use information that the Company regards as
proprietary. Policing unauthorized use of the Company's technology and
products is difficult. In addition, the laws of many countries do not protect
the Company's information, technology and intellectual property that it
regards as proprietary to as great an extent as do the laws of the United
States. There can be no assurance that the Company's protective measures will
be adequate or that the Company's competitors will not independently develop
similar information, technology or intellectual property.
 
  To date, the Company has not been notified of any claim that the Company's
products infringe the proprietary rights of third parties, but there can be no
assurance that third parties will not claim infringement by the Company with
respect to current or future products. Any such claims, with or without merit,
could be time-consuming, result in costly litigation, cause product shipment
delays or require the Company to enter into royalty or licensing agreements.
Such royalty or licensing agreements, if required, may not be available on
terms acceptable to the Company or at all, which could have a material adverse
effect upon the Company's business, financial condition or results of
operations. See "Business--Patents and Proprietary Rights."
 
  Risks Associated with International Sales. The Company may expand its sales
and marketing activities outside of the United States, which will require
management attention and financial resources. There can be no assurance that
such efforts will be successful. International operations are subject to a
number of risks, including longer receivable collection periods and greater
difficulty in accounts receivable collections, unexpected changes in
regulatory requirements, dependence on independent resellers, risks of foreign
currency fluctuations relative to the U.S. dollar, import and export
restrictions and tariffs, difficulties and costs of staffing and managing
foreign operations, potentially adverse tax consequences, political
instability, the burdens of complying with multiple, potential conflicting
laws and the impact of business cycles and economic instability outside the
United States.
 
  Government Regulation. The Company's operations are subject to extensive
government regulations pertaining to product manufacture, marketing and
distribution, and environmental, worker safety, export control and other
matters. Certain of the Company's technology and products, especially those
having nuclear energy or military applications, are subject to substantial
controls, including requirements to obtain governmental approvals and licenses
on their use, distribution, dissemination and export. Furthermore, the
diagnostic and other medical
 
                                      10
<PAGE>
 
products that the Company may develop in the future are subject to stringent
regulation by the FDA and its foreign counterparts, and within the United
States by certain state agencies. Regulations by the FDA and its counterparts
impose significant restrictions on the development, testing, manufacture,
marketing, distribution and export of such products, including in most cases
the need for prior approval from such government agencies to manufacture, test
and distribute such products. Regulatory approvals for commercial distribution
of medical and diagnostic products generally require substantial preclinical
and human clinical testing to demonstrate their safety and effectiveness.
There can be no assurance that clinical data from such studies will
demonstrate the safety or efficacy of any product that the Company may in the
future develop or of products utilizing components that the Company may desire
to supply, nor could there be any assurance that the FDA or its foreign
counterparts will approve the commercial distribution of any such products in
a timely manner, if at all. Likewise, to the extent that other foreign or
domestic government approvals or permits are required for the manufacture,
export, import, distribution and marketing of the Company's products and
operations, there can be no assurance that the Company will be able to obtain
or maintain such approvals or permits or meet applicable requirements or
standards, or that such approvals or permits will not contain restrictions or
limitations that materially affect the sale and distribution of the Company's
products. The Company's failure to obtain such approvals in a timely manner,
or its failure to comply with applicable foreign or domestic laws, regulations
or policies, including those applicable to its operations and products, or
changes in such laws, regulations or policies, may have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Government Regulation."
   
  Control by Existing Shareholders. Upon completion of this offering, the
directors, executive officers and principal shareholders of the Company and
their affiliates will, in the aggregate, assuming the exercise in full of all
options and warrants then outstanding, beneficially own approximately 45.7% of
the Company's outstanding Common Stock (approximately 43.3% if the
Underwriters' over-allotment option is exercised in full). As a result, these
shareholders, acting together, will possess significant influence as
shareholders of the Company, including concerning election of the Company's
Board of Directors and the approval of significant corporate transactions.
Such control could delay, defer or prevent a change in control of the Company,
impede a merger, consolidation, takeover or other business combination
involving the Company, or discourage a potential acquirer from making a tender
offer or otherwise attempting to obtain control of the Company. See
"Management" and "Principal Shareholders." The Company's bylaws provide that
so long as the Company is a "listed company" as defined by applicable
California law, there will not be cumulative voting in connection with the
election of directors. Upon the closing of this offering, however, the Company
will not be a listed company as so defined, and therefore cumulative voting
will apply in connection with the election of directors. See "Description of
Capital Stock--Common Stock."     
 
  Effect of Certain Charter Provisions. The Company's Board of Directors has
the authority to issue up to 10,000,000 shares of Preferred Stock and to
determine the rights, preferences, privileges and restrictions, including
voting rights, of those shares without any further vote or action by the
shareholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. The issuance of Preferred Stock could
adversely affect the voting power of holders of Common Stock and the
likelihood that such holders will receive dividend payments and payments upon
liquidation. Additionally, issuance of Preferred Stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of making it more difficult for a third party
to acquire a majority of the outstanding voting stock of the Company. The
Company has no current plans to issue shares of Preferred Stock.
   
  Limits on Secondary Trading; Possible Illiquidity of Trading Market. The
Company has applied to have the Common Stock and Warrants listed on the Nasdaq
SmallCap Market and the Boston Stock Exchange, which may be a significantly
less liquid market than the Nasdaq National Market. Moreover, if the Company
should be unable to maintain the standards for continued quotation on the
Nasdaq SmallCap Market, the Common Stock and Warrants could be subject to
removal from the Nasdaq SmallCap Market. Trading, if any, in the Common Stock
and Warrants would therefore be conducted on the Boston Stock Exchange
(assuming the Company     
 
                                      11
<PAGE>
 
   
continued to be listed on such exchange) and in the over-the-counter market on
an electronic bulletin board established for securities that do not meet the
Nasdaq SmallCap Market listing requirements, commonly referred to as the "pink
sheets." As a result, an investor would find it more difficult to dispose of,
or to obtain accurate quotations as to the price of, the Common Stock or
Warrants. In addition, depending on several factors including the future
market price of the Common Stock and Warrants, the Common Stock and Warrants
could become subject to the so-called "penny stock" rules that impose
additional sales practices and market making requirements on broker-dealers
who sell and/or make a market in such securities, which could affect the
ability or willingness of broker-dealers to sell or make a market in the
Common Stock and Warrants and the ability of purchasers of the Common Stock
and Warrants to sell their securities in the secondary market.     
   
  Under the blue sky laws of most states, public sales of Common Stock and
Warrants after this offering by persons other than the Company in "nonissuer
transactions" must either be qualified under applicable blue sky laws, or
exempt from such qualification requirements. As a condition of qualifying the
offer and sale of Securities in this offering in California, the California
Department of Corporations has initially indicated that public trading of
Shares and Warrants in California may generally be prohibited for at least 90
days after the closing of this offering. The Department is, however, reviewing
the Company's qualification application, and it is uncertain whether these
restrictions will be imposed. If secondary trading restrictions are imposed,
then following 90 days after the closing of this offering the Company intends
to apply for an exemption permitting secondary trading in California. Blue sky
authorities in other states may impose other restrictions on secondary trading
in those states. In many states, secondary trading will be permitted only so
long as information about the Company is published in a recognized manual such
as manuals published by Moody's Investor Service or Standard & Poor's
Corporation. The Company has applied for listing in a recognized manual and
will attempt to be so listed as soon after the closing of this offering as
reasonably practicable, but secondary trading in many states will be
restricted for some period of time after the date of this Prospectus.     
       
  Underwriting History. Pryor, McClendon, Counts & Co., Inc., one of the
Representatives, has not previously acted as a managing underwriter of a
public offering of equity securities, although it has participated as an
underwriter in several public offerings of equity securities and has
substantial experience as an underwriter in public offerings of debt
securities, including municipal bonds. Prospective purchasers of the
Securities offered hereby should consider such Representative's limited
experience in offerings such as this in evaluating an investment in the
Securities. See "Underwriting."
   
  Shares Eligible for Future Sale. Sales of a substantial number of shares of
Common Stock in the public market following this offering could adversely
affect the market price for the Common Stock or Warrants. However, the number
of shares of Common Stock that can be traded in the public market is limited
by restrictions under the Securities Act of 1933, as amended (the "Securities
Act"). In addition, holders of substantially all of the outstanding shares of
Common Stock and options and warrants to acquire Common Stock have entered
into lock-up agreements pursuant to which they have agreed not to sell or
otherwise dispose of any of their shares for a period of 12 months after the
initial closing date of this offering. As a result of these restrictions,
based on shares outstanding as of October 1, 1996, on the date of this
Prospectus, no shares other than the 850,000 Shares and 850,000 Warrants
offered hereby will be eligible for public sale, and approximately 1,911,111
currently outstanding shares will be eligible for public sale 12 months after
the initial closing date of this offering. Additional shares of Common Stock
issuable upon the exercise of certain outstanding options and warrants will
become eligible for public sale as a result of registration rights agreements
with the Company. See "Description of Capital Stock--Registration Rights." In
addition, the Company intends to register on a registration statement on Form
S-8, shortly after the effective date of this offering, a total of
approximately 587,134 shares of Common Stock reserved for issuance under
certain outstanding options and future options to be granted under the
Company's employee benefit plans. See "Shares Eligible for Future Sale."     
   
  Immediate and Substantial Dilution. Investors participating in this offering
will incur immediate, substantial dilution of $5.30 per share. To the extent
options or warrants to purchase Common Stock are exercised, there may be
further dilution. See "Dilution."

                           RECENT DEVELOPMENTS     
   
  Based on preliminary sales, operating and other data through October 31,
1996, the Company believes that total revenues for the three months ended
October 31, 1996 were approximately $800,000. In addition to sales to GE of
approximately 30% to 35% of net revenues, the Company continued direct sales
of DZ to end users, and for the three months ended October 31, 1996,
approximately 20% to 25% of net revenues were from sales made directly to end
users. Sales of cadmium and stable isotope labeled compounds represented
approximately 40% to 50% of net revenues during the period. Net revenues
decreased from approximately $1.6 million for the three months ended July 31,
1996. The decrease was due to the timing of DZ orders and the size of such
orders. The decrease in DZ net revenues was offset in part by increases in
sales of cadmium and stable isotope labeled compounds. Based upon such data,
the Company believes that it will incur a net loss for the period of
approximately $300,000 to $400,000.     
 
                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 850,000 shares of
Common Stock and Warrants offered hereby are estimated to be approximately
$4,677,000 ($5,403,000 if the Underwriters' over-allotment option is exercised
in full), after deducting estimated underwriting discounts and commissions and
offering expenses. The Company expects to use the net proceeds of this
offering as follows:

(1) The Company intends to apply these proceeds to repay approximately
    $1,372,000 payable under the notes issued in the Placement. See
    "Capitalization--Recent Financing Transactions" and "Certain
    Transactions."     
   
(2) The Company intends to conduct a feasibility study concerning construction
    of an isotope manufacturing facility, estimated at approximately $300,000,
    purchase equipment, estimated at approximately $550,000, and upgrade
    management information systems, estimated at approximately $80,000. See
    "Business--Manufacturing and Supply."     
   
(3) The Company intends to use a portion of the proceeds for general corporate
    purposes which may, among other purposes, include inventory purchases,
    accounts receivable financing and administrative salaries.     
 
  The foregoing represent estimates only, and the actual amounts expended by
the Company for these purposes and the timing of such expenditures will depend
on numerous factors. The Company may use a portion of the net proceeds to
acquire businesses or products complementary to the Company's business,
although the Company currently has no specific plans or commitments in this
regard. Pending use of the net proceeds for the above purposes, the Company
intends to invest such funds in short-term, interest-bearing, investment-grade
obligations and federally insured certificates of deposit.
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its capital
stock. The payment of any future dividends will be at the discretion of the
Company's Board of Directors and will depend upon, among other things, future
earnings, operations, capital requirements, the general financial condition of
the Company, general business conditions and contractual restrictions on
payment of dividends, if any. The Company currently anticipates that it will
retain all future earnings for use in its business and does not anticipate
paying any cash dividends in the foreseeable future.

(1) The Placement is reflected in the Pro Forma amounts as a borrowing and a
    sale of securities. See "--Recent Financing Transactions." The $1,372,000
    gross proceeds of the Placement has been allocated between the Placement
    Notes and Placement Warrants based on their estimated relative fair values
    at the date of issuance. The fair value of the warrants issued in
    connection with the Placement as estimated by the Company approximates
    $394,000. Expenses and discounts related to the issuance of the Placement
    Notes were $147,000. The Placement Notes are due upon closing of this
    offering. The "As Adjusted" amount includes a charge to retained earnings

RECENT FINANCING TRANSACTIONS
   
  In an August and September 1996 private placement (the "Placement"), the
Company issued approximately $1,372,000 principal amount of 12% nonconvertible
promissory notes (the "Placement Notes") and warrants (the "Placement
Warrants") to acquire 286,414 shares (the "Placement Shares") of Common Stock
to a small number of sophisticated investors (the "Placement Investors"). Net
proceeds were approximately $1,225,000.     
   
  The Placement Notes bear interest at 12% per annum and are due and payable
in full at the earlier of five business days after the Company receives funds
from this offering or May 1, 1998. Unless the Placement Notes are earlier paid
in full (i) accrued but unpaid interest at 12% per annum is due and payable
monthly from September 1996 through May 1997 and (ii) principal and accrued
but unpaid interest at 15% per annum is due and payable in equal installments
monthly from June 1997 through May 1998. The Company may prepay any or all of
the amounts due under the Placement Notes at any time without penalty. To
secure repayment of the Placement Notes, the Company entered into a security
agreement, granting a security interest to the Placement Investors in
substantially all of the assets of the Company. The security agreement and
certain provisions of California law govern the rights of the Placement
Investors in the collateral, the events of default which authorize their
resort to the collateral, and the procedures governing the treatment and
disposition of the collateral if the Placement Investors elect to resort to
the collateral in the event of such default. Upon repayment of the Placement
Notes, the collateral will be released in full.     
   
  Placement Warrants to purchase 143,207 Placement Shares are exercisable in
whole at any time or in part at $.4217 per share, and Placement Warrants to
purchase 143,207 Placement Shares are exercisable in whole at any time or in
part at $3.3727 per share, in each case for a period of five years. If the
Company defaults in its payment obligations under the Placement Notes, then
the Placement Investors may, in addition to exercising their rights in the
collateral, exercise additional Placement Warrants to purchase a total of
approximately 377,458 additional Placement Shares (such warrants referred to
as "Default Warrants") at $.01 per share, and can require the holders of
approximately 1,387,810 shares of Common Stock to vote their shares to elect
as a majority of the Company's Board of Directors the designees of the
Placement Investors. In conjunction with the financing, the Company issued
warrants to purchase 127,721 shares of Common Stock exercisable for a period
of five years at $1.378 per share to an advisor.     
 
  The Company intends to repay the Placement Notes out of a portion of the net
proceeds of this offering. See "Use of Proceeds." As a result, after the
closing of this offering no Placement Notes will remain outstanding, and no
Default Warrants will be issued.
 
  The Company has agreed to file at its expense a registration statement under
the Securities Act no later than nine months after the effectiveness of this
offering registering the resale of the Placement Shares, and the Placement
Investors have certain additional piggyback registration rights. See
"Description of Capital Stock--Registration Rights."
   
  An aggregate discount of $541,000 will be amortized to interest expense over
the contractual life of the Placement Notes. This discount is comprised of
$394,000 representing the fair value of the warrants issued in connection with
the Placement, $137,000 representing discounts on the Placement Notes and
$10,000 representing expenses of the Placement. Accordingly, in the quarter in
which this offering is completed, the amount of the discounts which have not
already been amortized will, be recorded as a charge to operations for debt
restructuring (as an extraordinary item) and will be reflected in the
Company's statement of operations for that period. The charge is likely to
have a material effect on the Company's reported earnings for that quarter,
and as a result the Company expects to have a significant net loss for the
quarter in which the offering occurs.     
   
  Certain of the Company's directors, employees, and other related persons
participated in the Placement. See "Certain Transactions."

                                   DILUTION
   
  The net tangible book value of the Company as of July 31, 1996 was $17,000
or $.01 per share of Common Stock. The July 31, 1996 book value was adjusted
for the following items: (i) the conversion of the preferred shares, (ii) the
exercise of options by two of the Company's executive officers in September
1996 to purchase an aggregate of 217,706 shares of Common Stock at an exercise
price of $1.52 per share and (iii) the exercise of options by one employee of
the Company in September 1996 to purchase 97,671 shares of Common Stock at an
average exercise price of $2.07 per share. The Company loaned the two
executive officers $165,000 each representing the purchase price for the
options, and the officers executed promissory notes reflecting these loans.
Under Generally Accepted Accounting Principles ("GAAP"), such promissory notes
are shown as a reduction of shareholders equity. Therefore, the promissory
notes have not been reflected as tangible assets for purposes of the dilution
table. Net tangible book value per share is determined by dividing the amount
of total tangible assets of the Company less total liabilities by the number
of shares of Common Stock outstanding at that date. After giving effect to the
sale of the 850,000 shares of Common Stock and 850,000 Warrants offered by the
Company hereby at an assumed initial public offering price of $7.00 per Share
and ascribing no value to the Warrants for this purpose, and after deducting
the estimated underwriting discounts and commissions and offering expenses,
the pro forma net tangible book value of the Company as of July 31, 1996, as
adjusted, would have been $4,694,000 or $1.70 per share. This represents an
immediate increase in net tangible book value of $1.69 per share to existing
shareholders and an immediate dilution of $5.30 per share to new investors
purchasing Common Stock and Warrants at the initial public offering price. The
following table illustrates the per share dilution.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULT OF OPERATIONS
 
OVERVIEW
 
  The business of the Company was founded in March 1992 and was initially
conducted as a partnership. In March 1993, the Company was incorporated and
the business was transferred to the Company. The Company was initially engaged
in the business of marketing non-radioactive stable isotopes for the energy
industry. During fiscal 1996, the Company expanded its business operations to
include developing specialty chemicals and materials, and conducting research
and development concerning potential products, for the medical research,
diagnostic, pharmaceutical and semiconductor industries. The Company believes
that a substantial portion of its revenues in the future will depend on its
success in developing and selling products in these markets.
 
  The Company's quarterly operating results have varied in the past and may in
the future vary significantly, depending on factors such as the size and
timing of customer orders, price and other competitive conditions and the
timing of new product announcements and releases by the Company and its
competitors. The Company operates with little order backlog. Moreover, a
significant portion of the Company's total revenues have been, and the Company
believes will continue to be, derived from a limited number of orders in any
particular quarter, and the timing of such orders and their fulfillment has
caused, and is likely to continue to cause, material fluctuations in the
Company's operating results, particularly on a quarterly basis. As a result, a
lost or delayed sale could have a significant impact on the Company's
operating results for a particular period. It is likely that in some future
quarter, the Company's operating results will be below the expectations of
public market analysts and investors. In such event, the price of the Common
Stock would likely be materially adversely affected.
 
  The Company has experienced, and expects to continue to experience,
significant fluctuations in its results of operations. See "Risk Factors."
Some of the factors that affect the Company's results of operations include
the volume and timing of orders received, changes in the mix of products sold,
market acceptance of the Company's and its customers' products, competitive
pricing pressures, the Company's ability to develop and introduce new
products, and the timing and extent of research and development expenses. As a
result of the foregoing or other factors, there can be no assurance that the
Company will not experience material fluctuations in future operating results
on a quarterly or annual basis, and such fluctuations could materially and
adversely affect the Company's business, financial condition and results of
operations.
   
  Historically, substantially all of the Company's net revenues in any
particular period have been attributable to a limited number of customers. Net
revenues from GE accounted for 66%, 59% and 88% of net revenues for the three
months ended July 31, 1996, and the years ended April 30, 1995 and 1996,
respectively. One other customer accounted for 20% of net revenues for the
three months ended July 31, 1996. A second customer accounted for 10% of net
revenues for the three months ended July 31, 1996. A third customer accounted
for 11% of net revenues for the years ended April 30, 1995 and 1996. A fourth
customer accounted for 26% of net revenues for the year ended April 30, 1995.
The Company expects that if it continues to increase sales of depleted zinc
products to end users and develop and sell products in the medical and
research and electronic materials industries, concentration of net revenues
from a limited number of customers will be reduced. None of the Company's
customers have entered into long-term agreements to purchase the Company's
products. If completed sales orders are not replaced on a timely basis by new
orders from customers, the Company's net revenues could be materially and
adversely affected. The Company's net revenues also could be adversely
affected by a number of factors including the loss of a significant customer,
reductions in orders from any significant customer compared to historical
buying levels or otherwise or the cancellation of a significant order from a
customer. Any of these factors, many of which are outside the Company's
control, could have a material adverse effect on the Company's business,
financial condition and results of operations.     
   
  In March 1995, the Company acquired certain assets and assumed certain
liabilities of Isoserve, Inc. ("Isoserve"), a stable isotope supplier. The
acquisition was accounted for as a purchase. The Financial Statements for the
fiscal year ended April 30, 1995 include the operations related to Isoserve
from March 28, 1995. See note 10 to the Financial Statements. Isoserve was the
only other supplier of DZ in the world at the     
 
                                      18
<PAGE>
 
   
acquisition date. By virtue of its acquisition of the Isoserve assets and
assumption of liabilities, the Company effectively became the sole source for
DZ worldwide. Management believes this acquisition has had a significant
positive impact on the Company's net revenues in fiscal 1996 as compared to
1995, and the Company cannot determine what the results of operations from
sales of DZ would have been in fiscal 1996 had the Company not acquired
Isoserve. Net sales of DZ were approximately $4.9 million in fiscal 1996 as
compared to $430,000 in fiscal 1995. By virtue of its position as the sole
worldwide supplier of DZ in 1996, the Company was able to increase unit
shipments and per unit selling price while keeping production costs stable,
thus increasing its gross margin on sales of DZ.

  Net Revenues. Net revenues increased from $738,000 in fiscal 1995 to $5.6
million in fiscal 1996. The increase was due primarily to demand for energy
products. Unit shipments of energy products increased by a factor of
approximately seven and average unit prices increased slightly as a result of
additional processing performed by the Company. The increase in shipments and
average unit prices was in part attributable to the acquisition of Isoserve.
To a lesser extent, net sales in fiscal 1996 increased from the introduction
of a new product, cadmium, which is used for laser holography applications.
Cadmium sales represented less than 15% of net revenues in fiscal 1996.     
   
  Net revenues for the three months ended July 31, 1996 were $1.6 million
compared to $1.2 million for the three months ended July 31, 1995, an increase
of approximately $400,000 or 33%. The increase was due primarily to demand for
energy products and cadmium. Net revenues from energy product sales increased
approximately $213,000 as a result of increased unit shipments and average
unit prices. Average unit prices of energy products were positively affected
by the Company's direct sales to end users. Net revenues from cadmium
increased approximately $107,000 on increased unit shipments, but average unit
prices decreased significantly as a result of competition in the market.     
       
  International sales represented 14%, 13%, 18% and 20% of net revenues for
fiscal 1995, 1996 and the three months ended July 31, 1995 and 1996,
respectively. International sales were principally to Asia and are denominated
in U.S. dollars.

  Gross Margin. Gross margin is affected by the volume of product sales,
product mix and average selling price. The Company's gross margin increased
from 15.2% of net revenues in fiscal 1995 to 31.1% in fiscal 1996. The gross
margin in fiscal 1995 was negatively impacted by competitive pricing
pressures. Gross margin in fiscal 1996 increased in part from the acquisition
of Isoserve, a supplier of depleted zinc oxide, which contributed to increased
per unit selling price and relatively stable production costs. Gross margin
for fiscal 1996 also improved from sales of cadmium.
 
  The Company's gross margin percentage decreased to 28.2% in the three month
period ended July 31, 1996 from 32.2% in the comparable period of the prior
year, due to increased raw material costs associated with the production of
energy related products which was offset in part by increased sales prices.
Gross margin percentage was also negatively affected by discounts given to
customers for prompt payment.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from $293,000 in fiscal 1995 to $902,000 in
fiscal 1996; however, as a percentage of net revenues such expenses decreased
from 39.7% to 16.2% of net revenues, respectively. The increase on a dollar
basis was primarily due to expanded marketing, business development and
administrative activities, while the decrease as a percentage of net revenues
was due to significant revenue growth.
 
  Selling general and administrative expenses increased from $186,000, or
15.6% of net revenues, to $266,000, or 17.0% of net revenues, for the three
months ended July 31, 1995 and 1996, respectively. The increase was due to
additional staffing for medical, research and diagnostics products and for
finance and administration. The Company anticipates selling, general and
administrative expenses will generally continue to increase in absolute
dollars, but may vary as a percentage of net revenues.
   
  Research and Development Expenses. Research and development expenses include
costs associated with new product development. Research and development
expenses increased from $162,000 in fiscal 1995 to $308,000 in fiscal 1996;
however, as a percentage of net revenues such expenses decreased from 22.0% to
5.5% of net revenues, respectively. The increase in fiscal 1996 on a dollar
basis from the prior year reflected the Company's continued efforts to remain
competitive through investments in product development by increased staffing,
while the decrease as a percentage of revenues was due to significant revenue
growth and working capital limitations which prevented additional research and
development expenditures.     
 
  Research and development expenses increased from $59,000, or 5.0% of
revenues, to $90,000, or 5.8% of revenues, for the three months ended July 31,
1995 and 1996, respectively. The increase was due to increased staffing for
product development. The Company believes that the development and
introduction of new product applications is critical to its future success and
expects that research and development expenses will increase on a dollar basis
and as a percentage of revenues in the future.
 
  Other Expense, Net. Other expense reflects interest incurred by the Company
on its long and short-term borrowings. Other expense, net, increased from
$15,000 in fiscal 1995 to $66,000 for fiscal 1996, and from $3,000 to $12,000
for the three months ended July 31, 1995 and 1996, respectively, but remained
consistent as a percentage of net revenues.
 
  Income Taxes. For fiscal 1995 and 1996, the income tax expense (benefit) was
$(215,000), or (29.1)% of net revenues, and $175,000, or 3.1% of net revenues,
respectively. The effective tax benefit rate of 60% in fiscal 1995 differed
from the federal statutory rate due principally to the realization of
temporary differences and loss carryforwards and the determination that such
differences were realizable. The Company's effective tax rate of 39% in fiscal
1996 differs from the statutory rate due to state income taxes, net of the
federal benefit.
 
  The provision for income taxes was $52,000 and $30,000 for the three months
ended July 31, 1995 and 1996, respectively. The Company's effective tax rate
of 38% and 41% differs from the statutory rate due to state income taxes, net
of the federal benefit.

  Extraordinary Item. As a result of the Placement Notes issued in the
Placement, the Company is amortizing to interest expense an aggregate discount
of $541,000 over the contractual life of the Placement Notes. In the quarter
in which this offering is completed, the amount of the discount which has not
already been amortized will be recorded as a charge to operations for debt
restructuring and is expected to be shown as an extraordinary item and will be
reflected in the Company's statement of operations for that period. The charge
is likely to have a material adverse effect on the Company's reported earnings
for that quarter, and as a result the Company expects to have a significant
net loss for the quarter in which the offering occurs. As of October 31, 1996,
approximately $490,000 of the discount remained to be amortized. See
"Capitalization--Recent Financing Transactions."     
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has primarily financed its operations through a
combination of cash flow from operations, borrowed funds, lease financing and
private sales of equity securities. The Company generated cash flow from
operating activities of $180,000 in fiscal 1996, principally as a result of
net income, adjusted for non-cash items, increases in accounts payable and
income taxes payable offset by increased inventory. Cash used by operations of
$96,000 in fiscal 1995 was principally a result of the net loss during the
period and adjustments for non-cash items, offset by increases in accounts
payable and accrued liabilities. The Company generated cash flow from
operating activities of $78,000 for the three months ended July 31, 1996,
principally as a result of net income, adjusted for non-cash items, and
increases in accounts payable offset by increased inventory and decreases in
accrued liabilities.
 
  The Company's investing activities used cash of $57,000, $7,000, $2,000 and
$4,000 in 1995 and 1996 and the three months ended July 31, 1995 and 1996,
respectively. Such investing activities were principally for purchases of
property and equipment and the cash paid for the acquisition of Isoserve in
fiscal 1995.
 
  Financing activities used cash of $95,000, $49,000 and $43,000 in fiscal
1996 and the three months ended July 31, 1995 and 1996, respectively, and
provided cash of $187,000 in fiscal 1995. Financing activities in fiscal 1996
consisted of the issuance of notes which were more than offset by payments of
principal, while financing activities for the three months ended July 31, 1996
consisted of debt repayments. Financing activities in fiscal 1995 consisted of
the issuance of notes and preferred stock which were offset in part by
payments of principal.
   
  The Company is required to make royalty payments to Isoserve for each gram
of depleted zinc metal sold until March 2000. Minimum annual royalty payments
of $100,000 are required regardless of sales volume until the Company has paid
$500,000 in the aggregate. The maximum royalty payments under the agreement
are $1,000,000. As of July 31, 1996, the Company has paid cumulative royalties
of $241,000 to Isoserve, of which $45,000 was paid in the three months ended
July 31, 1996.     
   
  As of April 30, 1995 and 1996, and July 31, 1996 the Company had negative
working capital of $248,000, $61,000, and $134,000, respectively. These
working capital deficiencies were the result of the significant losses from
operations in the Company's early stages as it incurred expenses to establish
its market position. The Company believes that the net proceeds of this
offering will eliminate these working capital deficiencies upon the closing of
this offering. At present, the Company has no credit facility with a bank or
other financial institution and no in-place source of capital, other than the
approximately $1,125,000 net proceeds of the Placement, see "Capitalization--
Recent Financing Transactions." The Company intends to use a portion of the
net proceeds of this offering to repay the Placement Notes. The Company is
also considering building an isotope manufacturing facility. The Company
intends to use a portion of the net proceeds of this offering to conduct a
feasibility study concerning such a facility. If the Company decides to
proceed with construction of such a facility, additional financing would be
required. The Company currently has no arrangements for loans or other
financing relating to any such construction. The unavailability of such
financing could adversely affect its ability to increase sales of new
products. The additional funding, if needed, may not be available on terms
attractive to the Company, if at all. While the timing and amount of capital
requirements cannot be predicted with certainty, the Company believes that
cash on hand at July 31, 1996, together with the proceeds from the Placement
and the     
 
                                      21
<PAGE>
 
net proceeds from this offering will be sufficient to allow the Company to
continue its expected level of operations for at least 12 months from the date
of this Prospectus. Any additional equity financing may be dilutive to
shareholders, and debt financing, if available, may involve restrictive
covenants. See "Use of Proceeds" and "Risk Factors--Future Additional Capital
Requirements."

                                   BUSINESS
 
  Isonics is an advanced materials and technology company which develops and
commercializes products based on enriched stable isotopes and high purity
materials. Stable isotopes can be thought of as ultra-ultra pure materials.
This high degree of purification accomplished on the sub-atomic level provides
enhanced performance properties compared to normal purity materials. Stable
isotopes have commercial uses in several areas, including energy; medical,
research, diagnostics and drug development; product tagging and stewardship;
semiconductors; and optical materials. Isonics has successfully developed and
commercialized two stable isotope products and intends to promote the
emergence and growth of new stable isotope applications.
 
  The Company's principal product to date is isotopically depleted zinc
("DZ"). DZ, in different chemical forms, is used to prevent corrosion in
nuclear power plants. Corrosion is a cause of high radiation fields in such
plants and can result in radiation exposure to workers. DZ also reduces
environmental cracking in certain kinds of nuclear reactors which, if not
controlled, can require extremely costly repairs or can result in premature
shutdown and de-commissioning of the facility. The Company believes that it
provides substantially all of the DZ used in nuclear power plants worldwide.
   
  The application of DZ was developed by General Electric Company ("GE"),
where the founders of the Company were previously employed. Before May 1996,
all sales of DZ by the Company were made to GE pursuant to sales orders, which
in turn resold the product to end users. In addition to sales to GE, in May
1996 Isonics commenced direct sales to end users, and for the three months
ended July 31, 1996, approximately 10% of net revenues were from sales made
directly to end users.     
 
  New applications for stable isotopes are continually being developed by the
Company and by third parties. The Company believes that many new applications
have the potential to create new markets. One opportunity is to supply stable
isotope labeled compounds for the diagnostic breath test ("DBT") market. DBTs
provide early diagnosis of conditions that could otherwise lead to expensive
procedures such as endoscopies and biopsies. DBTs under development by third
parties which utilize stable isotopes in their application include tests to
diagnose peptic ulcers, fat malabsorption and liver function. A urea DBT
relating to peptic ulcers has recently been approved by the U.S. Food and Drug
Administration (the "FDA"), and the Company believes that other companies have
applied to the FDA or comparable agencies in foreign countries for approval of
these tests, which must be obtained before any products can be sold. Certain
DBTs are currently marketed in certain European countries.
 
  The Company holds an option, subject to satisfaction of certain conditions,
to acquire an exclusive license to two Yale University patents which cover
semiconductor devices made of isotopically pure silicon, germanium, gallium
arsenide and most isotopically pure compound semiconductors. The patents claim
that isotopic purity provides improved device speed and improved thermal
conductivity, two properties which are of great importance to the
semiconductor industry. According to the Semiconductor Industry Association,
sales in 1995 of silicon wafers and other semiconductor substrates were
approximately $6 billion. The Company is collaborating with Yale to evaluate
these isotopically engineered semiconductor applications. The Company believes
that if evaluations demonstrate the commercial feasibility of one or more
products, demand could emerge in certain segments of the semiconductor market.
There can be no assurance, however, that these evaluations will demonstrate
the commercial feasibility of any products, that the Company will be able to
commercialize any such products or that a market will emerge for any such
products.
 
  The Company was formed in March 1992 and incorporated in California in March
1993 under the name A&R Materials, Inc. In September 1996, the Company changed
its name to Isonics Corporation. The Company's principal executive offices are
located at 4010 Moorpark Avenue, Suite 119, San Jose, California, 95117. Its
telephone number is (408) 260-0155.

BACKGROUND
 
  The following discussion utilizes several technical terms which are
explained in greater detail in the Glossary preceding the financial statements
at the end of this Prospectus.
 
  An isotope is one of two or more species of the same chemical element which
differ from one another only in the number of neutrons in the nucleus of the
atom. The different number of neutrons can create significantly different
nuclear physics characteristics. To take advantage of some of these different
characteristics, it is usually necessary to increase ("enrich") or decrease
("deplete") the concentration of a particular isotope. There are over 280
naturally occurring stable isotopes of 83 elements. Some elements have only
one naturally occurring stable isotope, while others have many. Stable
isotopes are not radioactive.
 
  Stable isotopes of an element differ in mass and diameter as well as several
nuclear properties, such as cross-section, spin and magnetic moment.
Differences in these properties can result in substantially different effects,
and some of these differences have the potential for commercial application.
For example, in ultra chemically pure crystals grown for electronics or
optical applications, isotopic impurities are the greatest contributor to
crystal disorder due to mass and diameter variations. Eliminating this
disorder by using a single enriched isotope results in increased thermal
conductivity and optical transparency, and thus in improved product
performance. Similarly, enriching or depleting isotopes based upon their
cross-sections allows materials to be engineered for applications in the
nuclear power industry, for controlled doping of some semiconductors and for
use as targets to produce radioisotopes for medicine and industry.
 
  Stable isotopes of an element do not differ significantly in their chemical
behavior. Tagging of materials can be performed by varying the natural
abundance of isotopes to give a compound its own mass or nuclear magnetic
signature without changing its chemical properties. Though chemically
equivalent, the "tagged" or labeled compound is discernible from its unlabeled
twin through the use of several types of instruments called spectrometers.
 
COMPANY STRATEGY
 
  The Company believes that its strength is the ability to bring the necessary
elements together to identify, evaluate, develop, engineer and successfully
commercialize applications for stable isotopes and value-added products
manufactured from stable isotopes. This is evidenced by management's
experience (at the Company and in prior employment) in developing DZ from a
cost prohibitive concept to a commercial product. DZ is now one of the largest
worldwide commercial applications of a stable isotope product.
 
  The Company believes it has created a product development model that can
serve as a basis for current and future expansion efforts of the Company.
Isonics believes that coordination with the ultimate user to establish a
product specification and, with the Company's Russian partners, to establish a
cost effective product manufacturing process to meet that specification, has
the potential to make the Company a viable competitor. This coordination
process also includes initiating and managing development projects necessary
to adapt existing manufacturing methods to new missions, assembling and
coordinating necessary project-specific product and service suppliers,
obtaining appropriate regulatory approvals, and verifying product conformance
to stringent customer requirements.
 
  To capitalize on the commercial opportunities that have been identified for
stable isotopes, the Company has adopted a business strategy designed to
maximize the value of its technologies, business development and management
resources, while attempting to minimize capital costs arising from addressing
multiple markets. This strategy involves:
 
  . focusing on development of high value-added products which have a
    perceived competitive advantage in large or growing markets;
 
 
                                      24
<PAGE>
 
  . leveraging research and development expenditures through collaborations,
    government programs and corporate partnerships, including performing
    substantial work in Russia, where the Company believes an attractive
    value per dollar of cost can be obtained;
 
  . minimizing early capital needs by obtaining stable isotopes through
    alliances and supply agreements with Russian stable isotope sources,
    followed by investment in Company owned isotope production facilities
    when markets are more established and the optimum production technology
    has been determined;
 
  . obtaining value-added processing technology through sub-contract
    manufacturing agreements, joint ventures and acquisitions of
    strategically important technologies and companies; and
 
  . developing a time-balanced product pipeline to provide a continual supply
    of new business opportunities.
 
PRODUCTS
 
  The Company's product pipeline includes products with current revenues
(consisting of DZ, cadmium, medical imaging target materials and stable
isotope labeled compounds), and other potential products that may, but will
not necessarily, generate revenues beginning in future years (such as
manufactured labeled compounds, electronic materials and diagnostic breath
test substrates, isotopically pure semiconductor fabrication materials and
diagnostic breath test kits).
 
 Isotopically Depleted Zinc
 
  Maintaining radiation exposure of nuclear power plant workers to levels as
low as reasonably achievable is mandated in the U.S. by the Nuclear Regulatory
Commission. Also of significant concern is cracking of nuclear power plant
structural materials due to the corrosive nature of the water used to cool the
nuclear reactor core. Nuclear power plants are designed with substantial
safety margins against such cracking, and frequent surveillance is performed
to assure that this safety margin is not compromised. If not controlled,
cracking can require extremely costly repairs or, if not reparable, can result
in premature shutdown and de-commissioning of a facility which may have cost
hundreds of millions of dollars or more to construct.
 
  Testing sponsored by the Electric Power Research Institute has shown that
the addition of a soluble form of zinc to the nuclear reactor coolant reduces
plant radiation fields, and in some cases, substantially mitigates
environmentally induced cracking. Zinc acts as a corrosion inhibitor for the
stainless steel and other metal components of the nuclear reactor systems. In
boiling water reactors ("BWRs"), zinc prevents the development and
concentration of corrosion products, the cause of high radiation fields which
can result in radiation exposure to plant workers. In pressurized water
reactors ("PWRs"), zinc not only prevents radiation field build-up, but has
been shown in a PWR test to substantially reduce environmental cracking.
   
  Zinc provides the important benefits outlined above, but one isotope of
natural zinc becomes radioactive in the nuclear reactor, thus offsetting a
substantial portion of the desired benefits. By depleting this zinc isotope,
the desired benefits are still obtained while the detrimental side effect is
essentially eliminated. This product is known as isotopically depleted zinc
("DZ").     
 
  DZ is currently sold to 19 of the approximately 95 BWRs in the world
including 16 of the 37 U.S. BWRs. Typical current annual DZ requirements for a
BWR utilizing DZ are approximately $250,000 to $350,000, based on current
prices. No PWRs are currently adding either natural zinc or DZ on a routine
basis; however, the Company believes that one or more PWRs may in the near
future begin doing so. Programs to evaluate the effectiveness of utilizing DZ
at PWRs are planned or underway in the United States and certain foreign
countries. If these programs demonstrate the commercial effectiveness of DZ
for PWRs, the Company believes that a market may develop for DZ use in PWRs,
due in part to the importance of environmental cracking mitigation. Initial
test results suggest that PWRs will probably use a smaller amount of DZ per
plant as compared to BWRs, but there are approximately 200 PWRs in the world.
At present prices, the Company estimates the potential market for sales to
nuclear power plants to be between approximately $50-$70 million. There can be
no
 
                                      25
<PAGE>
 
assurance that a market will develop for DZ sales to PWRs, that the Company
will be able to sell DZ to all such potential customers, or that selling
prices of DZ will not decrease.
   
  Sales of DZ are presently the Company's largest source of revenues,
representing approximately 59%, 88% and 76% of net revenues in fiscal 1995 and
1996 and the three months ended July 31, 1996, respectively. In March 1995,
Isonics acquired the stable isotope business of Isoserve. The Company and
Isoserve have supplied substantially all of the DZ used in nuclear power
plants in the world to date. Until May 1996, DZ was sold only to GE, which in
turn resold it to the end-user nuclear power utilities. The Company's sales of
DZ to GE have been pursuant to sales orders placed from time to time by GE,
and the Company does not have any written purchase or sales agreements with GE
relating to sales of DZ or other products. In addition to sales to GE, the
Company currently is marketing DZ directly to U.S. and foreign utilities and
concluded its first direct end-user sale in May 1996. The Company believes
that direct sales to end users may increase in the future, while sales to GE
may remain level or decrease. There can be no assurance as to the size of
orders, if any, from direct end users in the future or as to the number of
customers that can purchase DZ from the Company. See "Risk Factors--Number of
DZ Customers."     
 
  The Company believes that the decision to purchase DZ is price sensitive.
The Company is actively working to further reduce costs by utilizing in-house
production of raw materials, developing and implementing low-cost zinc oxide
processing technologies, and providing DZ in innovative forms which lowers the
utilities' overall cost.
 
 Cadmium
 
  Sales of cadmium isotopes are presently the Company's second largest source
of revenues, representing approximately 11%, 11% and 20% of net revenues in
fiscal 1995 and 1996 and the three months ended July 31, 1996, respectively.
The Company sells enriched cadmium for use in helium cadmium lasers. Cadmium
isotopes may also be used for the manufacture of radioisotopes and might be
used in semiconductors and cadmium vapor lighting products.
 
  In a helium cadmium laser, cadmium is vaporized and behaves like a gas along
with helium. Enriched cadmium is routinely used in these lasers to achieve
optimum performance. Tests by laser manufacturers have shown that by using
only a single, even isotope of cadmium, such as cadmium-114, the power output
of a laser can be increased by at least 50% and the laser light coherence can
be improved significantly.
 
 Stable Isotope Labeled Compounds
 
  Stable isotope labeled compounds ("SILCs") are created by incorporating
carbon, nitrogen, hydrogen and oxygen isotopes into several thousand relevant
chemical compounds. SILCs allow researchers to probe the metabolism of living
systems, determine the structures of important biological compounds, design
new drugs and measure extremely low levels of environmental toxins. The
Company believes that greater availability of stable isotopes and advances in
instrumentation (improvements in sensitivity and reduced cost) will promote
increased demand for SILCs. Examples of existing and emerging applications
include:
 
  . Metabolic studies. Increasingly, drug studies are performed with labeled
    drugs to facilitate research on metabolism, distribution, mode of action
    and elimination. The FDA may eventually mandate the labeling of all new
    drugs for investigational use during some or all phases of pre-clinical
    and clinical evaluations of these drugs, but there can be no assurance
    that the FDA will make this mandate in the near future, if at all.
 
  . Rational drug design. Nuclear magnetic resonance ("NMR") spectroscopy is
    being developed as a tool to determine the structure of larger and larger
    molecules in solution, many of which cannot be analyzed by the more
    traditional x-ray crystallography techniques. The Company believes that
    this new NMR sensitivity combined with the sophisticated isotopically
    labeled cell growth media needed to produce the labeled human proteins
    will require an increasing supply of the stable isotopes of carbon,
    nitrogen and deuterium.
 
                                      26
<PAGE>
 
  . Product tagging and stewardship applications. The source of materials and
    explosives may be identified, without changing their chemistry, by
    tagging with the stable isotopes of carbon, nitrogen, oxygen and
    hydrogen. Several other approaches are currently being implemented, and
    other technologies have also been proposed. These other approaches
    involve the addition of extraneous materials such as dyes, exotic
    chemical compounds or radioactive compounds. The Company believes that
    adding such extraneous materials can sometimes detract from the
    performance of the product. Tagging with small amounts of isotopically
    engineered versions of the material itself results in a unique identifier
    which behaves chemically in exactly the same way as the host material.
 
  The Company's efforts to date in the production and sales of SILCs have
focused on structurally simple "building block" compounds which are used to
synthesize more complex and higher value SILCs. The Company presently markets
carbon-13 and nitrogen-15 building block SILCs which it obtains through its
supply alliance and network of stable isotope producers. See "--Manufacturing
and Supply." The Company intends to expand into the synthesis of more complex
SILCs. In addition to providing additional revenue potential and possibly
higher margins, the Company believes that developing complex SILC synthesis
capability is synergistic with the Company's breath test diagnostics
development efforts and will aid the Company in early identification of future
stable isotope business opportunities. To effectively implement this product
expansion strategy, the Company believes that it is necessary to establish its
own isotope enrichment capability and to obtain cost-competitive SILC
synthesis technology. See "--Manufacturing and Supply." The Company is
recruiting personnel with the requisite chemical synthesis skills and labeled
compound market knowledge to establish a production laboratory. See "--
Facilities."
 
 Diagnostic Breath Tests
 
  Healthcare consumes a large amount of resources in the U.S. and worldwide.
The Company believes that substantial changes are taking place to control or
reduce the high costs of health maintenance. A significant trend is a general
shift from therapy to cost-effective prevention. Early diagnosis of conditions
which otherwise could require expensive therapies, such as surgical and
invasive diagnostic gastrointestinal procedures, could help diminish the risks
and expense of such subsequent procedures. The Company has elected to pursue
what it believes is a promising segment of this market: Diagnostic Breath
Tests ("DBTs").
 
  Breath tests are all based on the same principle and use a common instrument
to measure the result:
 
  . a small amount of a carbon-13 SILC (referred to as a substrate) is
    swallowed by the patient;
 
  . breath samples are collected at regular intervals; and
 
  . breath samples are analyzed for their carbon-13 content.
 
  Most DBTs are intended to replace unpleasant, costly and sometimes risky
procedures such as endoscopies and biopsies of the digestive system. The
Company believes that DBTs may become a widely used and accepted diagnostic
tool. Certain DBTs are currently being sold in certain European countries.
Their ease of administration may allow medical internists and general
practitioners to use them, potentially resulting in lower cost, earlier
diagnosis and broader application.
 
  The market for DBTs is defined by the incidence of diseases addressed and
existing alternative diagnostic procedures. The urea breath test is the most
established DBT. If they become commercially available, carbon-13 urea breath
tests ("UBTs") may address a potential population of approximately 8 million
peptic ulcer patients in the U.S., who presently utilize drugs and procedures
with an estimated cost of at least $2 billion each year. The Company believes
that the UBT, coupled with antibiotic treatment, can reduce the cost of peptic
ulcer management. The Company believes that one company in the U.S. has
recently received FDA approval for a carbon-13 UBT, that another company has
applied for FDA approval for a carbon-13 UBT, and that several companies in
Europe, including Sanofi and Inbiomed in France, are also pursuing regulatory
approval. The Company intends first to enter this market as a carbon-13 and a
pharmaceutical-grade substrate supplier. The
 
                                      27
<PAGE>
 
initial step in pursuing this objective was the addition of Dr. Jacques
Delente, an experienced researcher and developer of breath test diagnostics,
to the Company's management team.
 
  The following table provides breath tests which are at various stages of
clinical research and pre-clinical and clinical trials by various third
parties.

  The DBT business is subject to extensive government regulation. The products
and instruments used, which may be regulated as drugs and devices, are subject
to the scrutiny of FDA review and approval as well as ongoing FDA inspection
of most aspects of the production, marketing, distribution and use of these
tests. The Company believes that the production and marketing of DBTs is also
subject to similar regulatory controls in the foreign countries where the
Company would likely seek to market products. Consequently, such products
cannot be commercially introduced for several years, and there can be no
assurance that the products would ever be approved for use.
 
  The DBT business is complex. The Company intends to enter the market
initially as a carbon-13 supplier or as a bulk supplier of carbon-13 SILCs
(substrates). The Company may also seek to develop a DBT measurement device
under the jurisdiction of the FDA. At some future date, the Company may seek
to become a more fully integrated supplier of DBT kits and measurement
instrumentation, although there can be no assurance that the Company will
pursue this strategy.
 
  In a parallel effort, the Company is currently exploring several options for
commercializing a UBT and other DBTs in Russia. Recent agreements between the
United States and Russia in the area of drug and device regulation allow for
more cooperation in the review and approval of new applications, such as DBTs.
Russian authorities already have in place or are working on similar agreements
with other countries. The Company believes that these agreements will simplify
and shorten the Russian process of approving health care products already
approved in countries with which they have agreements, although there can be
no assurance that this will be the case. The Company plans to capitalize on
its strengths in supplying carbon-13, labeled substrates, clinical knowledge
and data and regulatory support while looking for one or more local partners
with strengths in the Russian regulatory system, measurement hardware and
facilities, and marketing and sales capabilities. The Company also believes
this approach has the potential to improve its entry into the European market,
because of proximity, existing relationships and cost advantages.
 
 Medical Imaging and Therapy Materials
 
  Stable isotopes of thallium, zinc, cadmium, xenon, oxygen, strontium and
many others are routinely used in a variety of medical imaging and therapy
applications. In their enriched form or converted to a specific radioactive
isotope in a cyclotron or nuclear reactor, these materials are incorporated in
chemical compounds
 
                                      28
<PAGE>
 
which concentrate in specific parts of the human body upon injection,
inhalation or ingestion. Measuring the distribution of the materials in the
patient can assist physicians in diagnosing disease states and developing
appropriate treatment therapies, some of which incorporate radioactive
materials produced from stable isotopes.
   
  Most phases of the development and ongoing production of these materials are
controlled by the FDA and similar foreign regulatory agencies. This fact,
combined with the complexities of production and distribution, has resulted in
a market with only a few manufacturers. Tight quality control requirements and
the importance to the health care industry of a ready supply of these drugs
leads these manufacturers to pay close attention to their stable isotope
suppliers. Quality, supply reliability, ultimate source, breadth of offerings,
price and track record are principal factors that a manufacturer considers in
evaluating a potential stable isotope supplier. Much of the material used to
manufacture such products originates in countries of the former Soviet Union.
While the U.S. Department of Energy ("DOE") has facilities that can, and do,
manufacture stable isotopes, its costs are usually substantially higher
because of the full cost recovery mandated by legislation governing the DOE's
operations.     
   
  The Company is capable of supplying many of the stable isotopes currently
sold in this market. Since the original impetus for new applications of stable
isotopes in health care frequently comes from the drug manufacturers, the
Company has recently begun marketing its products, services and capabilities
to the existing and emerging manufacturers.     
 
 Isotopically Pure Semiconductors
 
  Isotopic purification of carbon used to manufacture synthetic diamonds has
resulted in substantially improved physical properties. Published tests
conducted by GE and others have shown that the removal of a small amount of
carbon-13 to produce isotopically pure carbon-12 synthetic diamonds can result
in a 50% improvement in room temperature thermal conductivity of the diamond.
At cryogenic (i.e., extremely cold) temperatures, the heat conductivity is so
great that it cannot be measured using conventional techniques. Additionally
the new diamond was found to be highly transparent, and the transmission of
certain frequencies of light was increased by approximately 10 times without
the diamond sustaining damage. GE has stated that isotopically pure carbon-12
diamonds may enable faster, more reliable computers due to their superior heat
removal capability and may result in more efficient laser cutting tools and
more accurate laser measurement devices, and that the new diamonds may enable
designers to use lasers in semiconductor fabrication techniques.
 
  Synthetic diamonds made from isotopically pure carbon-13 have been found by
Ford Motor Company scientists to have more atoms per cubic centimeter than any
other solid known to exist on earth. These isotopically pure carbon-13
diamonds are harder than any other presently-known material. Studies conducted
at Lawrence Berkeley Laboratory and the Max Planck Institute on isotopically
pure germanium have shown thermal conductivity improvements similar to those
found in isotopically pure carbon-12 diamonds.
 
  The Company believes that these and other improved properties might be found
in other isotopically pure materials and may result in commercial
opportunities, particularly in the area of semiconductors. According to the
Semiconductor Industry Association, the 1995 market for silicon wafers and
other semiconductor substrates was approximately $6 billion. This market is
projected to grow 50% by the year 1999 to over $9 billion. Improvement in the
thermal conductivity of these materials is important since as the feature size
continuously decreases, the power density increases. As power density
increases, more heat is generated per unit volume, causing device operating
temperature to rise. The semiconductor industry is moving toward lower
operating voltages and is using mechanical means to remove bulk heat, but the
Company believes that greater heat dissipation on the micro scale will become
even more important to the industry in the future. Better thermal conductivity
directly affects heat removal capability and indirectly improves device speed.
As the industry moves toward multi-layer devices and true 3-D chips, the
ability to remove heat will be a material consideration for the semiconductor
industry.
 
  Natural silicon contains three isotopes, silicon-28 (92%), silicon-29 (5%)
and silicon-30 (3%). An otherwise perfect crystal of silicon will contain
imperfections in the form of isotopes of different mass, with the density of
 
                                      29
<PAGE>
 
these imperfections amounting to nearly 8%. This far exceeds the doping levels
and density of imperfections ordinarily found in device-quality crystals. The
Company believes that removal of the minor isotopes should result in
substantially improved thermal conductivity.
 
  The Company believes that if commercial opportunities emerge, isotopically
pure silicon-28 (99.5%) deployed as wafers or substrates and as silane for
building epitaxial layers should find a niche in the manufacture of high
performance silicon semiconductors. Even at the premium price required for
isotopically pure silicon, the Company believes that it can compete in high
performance, less cost driven market segments.
 
  Isonics has obtained an option entitling it, upon the satisfaction of
certain conditions, to acquire an exclusive license regarding two U.S. patents
concerning isotopically pure semiconductor devices, which are owned by Yale
University. Yale's prior efforts to license its technology to semiconductor
manufacturers was hindered by Yale's inability to obtain the necessary
isotopically pure and chemically pure materials to evaluate its use. Since the
Company's stable isotopes could enable the development and commercialization
of the Yale technology, Yale chose to collaborate with the Company in
evaluating isotopically pure semiconductors. These patents cover silicon,
germanium, gallium arsenide and most isotopically pure compound
semiconductors. The Company is collaborating with Yale to evaluate possible
isotopically engineered semiconductor applications and their commercial
feasibility, including cost. The Company believes that if evaluations
demonstrate the commercial feasibility of one or more products, demand could
emerge in certain segments of the semiconductor market. There can be no
assurance, however, that these evaluations will demonstrate the commercial
feasibility of any products, that the Company will be able to commercialize
any such products or that a market will emerge for any such products. To
exercise the option, the Company must deliver to Yale before March 1997
specimens of isotopically pure silicon-28 meeting certain specifications. The
Company believes it will be able to satisfy this requirement, but there can be
no assurance that this will be the case. The option specifies that the terms
of the license shall be reasonable, but the terms may be no less favorable to
the Company than those specified in the option. The license, if obtained, will
require payment by the Company of an annual royalty based on a percentage of
the Company's or its sublicensees' net sales of products derived from
technology covered by the Yale patents. In addition, the license will permit
deduction of one-half of the Company's reasonable cost of securing the
silicon-28 from its future royalty payments to Yale University. Upon notice by
the Company of its exercise of the option, the Company and Yale are required
to negotiate in good faith to arrive at a license agreement within 90 days.
 
  In addition to silicon, the Company plans to evaluate a number of compound
semiconductors, such as gallium arsenide, which may particularly benefit from
enhanced heat dissipation capability.
 
RESEARCH AND DEVELOPMENT
   
  Consistent with the Company's product development strategy, a variety of new
stable isotope products and potential markets are continually being identified
and evaluated for economic and technical feasibility, and the Company intends
to devote a portion of the net proceeds of this offering for research and
development. See "Use of Proceeds." The Company funds research and development
to improve technologies for isotope separation and materials processing
technologies performed at Moscow State University and has retained consultants
to supervise the progress of such research. Much of the expenditures to date
have been in Russia to capitalize on the high quality of technology and
economical labor rates. The Company's activities in Russia could, however, be
directly affected by political, economic and military conditions in Russia.
See "Risk Factors--Operations in Russia."     
 
PATENTS AND PROPRIETARY RIGHTS
 
  The Company relies primarily on a combination of trade secrets,
confidentiality procedures and contractual provisions to protect its
technology. Despite the Company's efforts to protect its rights, unauthorized
parties may attempt to copy aspects of the Company's products or to obtain and
use information that the Company regards as proprietary. Policing unauthorized
use of the Company's technology and products is difficult. In addition, the
 
                                      30
<PAGE>
 
laws of many countries do not protect the Company's rights in information,
materials and intellectual property that it regards as proprietary to which it
regards as great an extent as do the laws of the United States. There can be
no assurance that the Company's means of protecting its rights in proprietary
information, materials and technology will be adequate or that the Company's
competitors will not independently develop similar information, technology or
intellectual property.
 
  The Company currently has no patents and has not filed any patent
applications. The Company has rights to several isotopically engineered
innovations regarding electronic and optical materials which it believes may
be patentable. Ongoing work in the area of isotope separation by biochemical
means may also lead to patentable inventions.
 
  To date, the Company has not been notified of any claim that the Company's
products infringe the proprietary rights of third parties, but there can be no
assurance that third parties will not claim infringement by the Company with
respect to current or future products. Any such claims, with or without merit,
could be time-consuming, result in costly litigation, cause product shipment
delays or require the Company to enter into royalty or licensing agreements.
Such royalty or licensing agreements, if required, may not be available on
terms acceptable to the Company or at all, which could have a material adverse
effect upon the Company's business, financial condition or results of
operations. See "Risk Factors--Protection of Intellectual Property."
 
COMPETITION
 
  The markets for the Company's products and proposed products are highly
competitive, and the Company expects that competition will continue and
increase as markets grow and new opportunities are realized. Some of the
Company's current competitors, and many of the Company's potential
competitors, are larger and have significantly greater financial, technical,
marketing and other resources. Some of the Company's competitors may form
partnerships or alliances with large pharmaceutical or electronics companies,
with the resulting entity possessing more market strength than the Company.
The Company's competition varies greatly depending on which product or
industry is considered.
 
  DZ. At present, the Company is the only producer of DZ, but believes that
other entities or persons may begin producing DZ. Several such possible
producers have adequate technical and financial resources to become viable
competitors of the Company in the near future. In particular, Siemens has
indicated that it has a relationship with Ultracentrifuge Netherlands ("UCN")
and GE has indicated that it intends to establish a second Russian source to
compete with the Company for GE purchases. UCN also competes with the Company
in the markets for cadmium and in medical target isotopes.
 
  SILCs. The Company has several larger and numerous smaller competitors in
the markets for the SILC products that the Company currently supplies, and
will have additional competitors if it offers breath test diagnostic products
and additional SILCs in the future. Two of these companies, Cambridge Isotope
Laboratories Inc., and Isotec, Inc., have their own isotope separation
capability, while all of the competitors produce some combination of SILCs and
DBT substrates. The Company believes that one company in the U.S. has recently
received FDA approval for a carbon-13 UBT, that another company has applied
for FDA approval for a carbon-13 UBT, and that several companies in Europe are
also pursuing regulatory approval. The Company's principal current competitors
and potential competitors include Tracer Technologies, Aldrich Chemicals, Icon
Services, MicroForest, Omicron, C/D/N Isotopes and Martek Biosciences. The
Company has in the past, and may in the future, sell products to or purchase
products from these companies.
 
  Electronics and Optical Materials. Due to the early stage of the electronic
and optical materials opportunities, the Company has not identified material
competitors in these markets. However, given the potential size and importance
of these new potential markets, the Company anticipates that substantial
competition will emerge if these markets develop.
 
 
                                      31
<PAGE>
 
  Many of the areas in which the Company is or intends to compete are rapidly
evolving. There can be no assurance that an existing or potential competitor
has already developed, or may develop, a patentable product or process which
will substantially prevent the Company from competing in its intended markets.
 
  The Company competes primarily on the basis of product performance,
proprietary position and price. Some of the Company's products may also
compete based on product efficacy, safety, patient convenience and
reliability. In many cases the first company to introduce a product to the
market will obtain at least a temporary competitive advantage over subsequent
market entrants.
 
MANUFACTURING AND SUPPLY
   
  Consistent with the Company's strategy to minimize capital expenditures, the
Company obtains stable isotopes through a multi-year supply agreement and, to
a lesser extent, from time to time from a variety of other Russian stable
isotope sources and may invest in Company-owned isotope production facilities
in the future upon determining the optimum production technology. Currently,
the Company obtains substantially all its isotopes from the former Soviet
Union.     
 
  The production of DZ is an international activity involving several distinct
steps which require up to nine months for the complete production cycle. First
the feed material, high purity diethylzinc, is procured from a chemical plant
in the United States and shipped by freighter to St. Petersburg, Russia. There
it is transported by truck or train to the gas centrifuge plant where it is
depleted of the zinc-64 isotope and converted to depleted zinc oxide. The
oxide form of DZ, which is acceptable for air freight, is then shipped to a
processing facility in the United States where additional chemical and
mechanical operations are performed to prepare the powder for use in nuclear
plants either as pellets or as a very fine grained powder. If the final
product form is pellets, further processing is performed in Ireland, but the
Company is pursuing development of the technology to perform this
manufacturing step in-house in the future.
   
  The Company has entered into an agreement with an isotope enrichment plant
located in Russia, which is owned by the Ministry of Atomic Energy of the
Russian Federation. The term of the agreement is through 1999. Under the
agreement, the plant will produce DZ and other stable isotopes for the Company
will allocate its stable isotope production capacity to the Company and will
produce other isotopes to respond to marketplace demand on the Company for
other stable isotopes. Under the agreement, the specific terms for each year's
production, including pricing terms, are negotiated between the parties by
November 1 of the preceding year, and the next such negotiation is expected to
occur in November 1996. If such an agreement is entered into, the agreement is
expected to provide, among other things, that the plant will exclusively
supply the Company and that disputes arising thereunder will be resolved by
arbitration conducted in Europe under international commercial arbitration
rules. Even if such an agreement is negotiated, the enforceability of the
agreement might be subject to the greater degree of uncertainty than if the
agreement was with a U.S. company and disputes were resolved in the U.S. The
supply of stable isotopes could be directly affected by political, economic
and military conditions in Russia. Accordingly, the operations of the Company
could be materially adversely affected if hostilities involving Russia should
occur, if trade between Russia and the United States were interrupted or
curtailed, or if the Company should fail to obtain and maintain all necessary
governmental approvals. Operations in Russia entail certain other risks,
including, among others, supply disruptions as well as introduction of tariffs
and fluctuations in freight rates. See "Risk Factors--Operations in Russia."
There can be no assurance that the Company's relationship with its processor
in Russia will be successfully maintained. Disruption or termination of the
Company's supply sources could delay shipments by the Company and could have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company does not presently maintain political risk
insurance but will evaluate the desirability and availability of such
insurance in the future.     
 
  To increase capacity and to geographically diversify the Company's
production of certain isotopes, the Company is considering constructing a
facility outside of Russia. The Company believes that owning this facility may
improve its profitability and will improve the security of its supply. The
Company intends to conduct a feasibility study to evaluate the nature and
timing of such a facility, and a portion of the net proceeds of this offering
will be used to fund that study. See "Use of Proceeds." The nature and timing
of any such construction
 
                                      32
<PAGE>
 
will depend on several factors, including the results of the study. If such a
facility is constructed, it is likely that the facility would be located in
North America.
 
  The Company depends upon a single processor, located in Russia, for one
process involved in the manufacturing of its products, and upon a single
supplier or a limited number of suppliers and processors for certain other
manufacturing processes. Although the Company does have written agreements
with certain of its suppliers and processors, the Company does not have any
written agreements with other suppliers and processors. The Company seeks to
reduce its dependence on its sole and limited suppliers, but disruption or
termination of any of the sources could occur, and such disruptions could have
at least a temporary material adverse affect on the Company's business,
financial condition and results of operations. Moreover, a prolonged inability
to obtain alternative sources for processing could materially adversely affect
the Company's relations with its customers.
 
GOVERNMENT REGULATION
 
 Regulation by government authorities in the United States and other countries
is a significant consideration in the development, production, distribution
and marketing of the Company's products and in its continuing research,
development, and other activities. In order to clinically test, manufacture,
distribute, market and sell products, especially those intended for
therapeutic or diagnostic use, mandatory procedures and safety and other
standards established by applicable regulatory authorities must be followed.
In many cases, specific approval to clinically test and commercially
distribute such products must be obtained from numerous governmental
authorities. Furthermore, the Company is subject to various laws, regulations
and requirements relating to such matters as the import and export of its
products, ensuring safe working conditions, laboratory and manufacturing
practices, the use and disposal of hazardous or potentially hazardous
substances used in connection with the Company's research, development and
manufacturing activities. Some of the regulations are summarized below. See
"Risk Factors--Government Regulation."
 
 FDA Regulation
 
  The Company's testing, manufacture, marketing, distribution, export and sale
of diagnostic products, such as any DBT it might in the future develop and
seek to sell, are subject to extensive and rigorous regulation by United
States and other countries in which the Company may choose to test,
manufacture or market its proposed diagnostic products. As of the date of this
Prospectus, the Company has not determined those countries, other than the
United States, where it might seek regulatory approvals to market any such
products it may develop. The products the Company intends to develop are
subject to rigorous preclinical and clinical testing and other FDA approval
requirements, and similar requirements in most other countries.
 
  The process for obtaining the required regulatory approvals from the FDA and
other regulatory authorities takes many years and can be expensive. The
Company has limited experience in conducting and managing the preclinical and
clinical testing necessary to obtain regulatory approvals and expects to rely
on experienced outside experts to assist as well as develop its own resources.
The various diagnostic products of which the Company is contemplating
development are subject to different regulations and other requirements.
Various components of the DBT and other products proposed for development are
regulated as drugs or medical devices under the Federal Food, Drug, and
Cosmetic Act ("FDCA"). The applicable FDA requirements for approval may be
different for different types or components of products.
 
  There can be no assurance that any product developed by the Company, or
other entities to which the Company may sell bulk or other materials, will
prove to meet all of the applicable standards to receive marketing approval,
or that any such approvals will be granted on a timely basis, if at all, or
that such products if approved will be commercially successful. Delays and
costs in obtaining these regulatory approvals could adversely affect the
Company's ability to commercialize its products and its ability to receive
market revenues. Even if regulatory approvals for a product are obtained, such
approvals may involve restrictions and limitations on the labeling and
clinical use of the product. Following market approval, the product will
continue to be subject to compliance with applicable federal and state laws
and regulations.
 
                                      33
<PAGE>
 
  The Company or the FDA may suspend clinical trials or commercial
distribution at any time if either determines that the subjects or patients
are being exposed to an unacceptable health risk related to the manufacturing,
testing and use of the Company's investigational or approved products, or if
the FDA determines that the Company has violated applicable laws or
regulations. If clinical studies are suspended, the Company may be unable to
continue development of the investigational products affected. Violation of
applicable laws and regulations, particularly those dealing with medical
products, can result in the imposition of substantial penalties against the
Company and its employees and officers, such as product seizures, recalls,
fines, injunctions and withdrawal or suspensions of approvals to test,
manufacture, export or market products. Delays and costs in obtaining or
reinstating these approvals and the subsequent compliance with applicable
federal and state statutes and regulations, and any penalties imposed for
their violation, could adversely affect the Company's ability to commercialize
products.
 
 Diagnostic Medical Device Products
 
  Certain diagnostic products that the Company may pursue, such as the DBT
products, are regulated as medical devices. Diagnostic products may be subject
to one of two marketing approval procedures. One procedure, known as a "510(k)
review," is available when the manufacturer can demonstrate that the proposed
product is "substantially equivalent" to another product that either was in
commercial distribution in the United States before May 28, 1976, or that has
been subsequently classified as a Class I or Class II medical device. When a
510(k) review is used, a sponsor is required to submit a Pre-Market
Notification to the FDA, at least 90 days before it plans to initiate
commercial distribution of the product.
 
  The Company cannot proceed with sales of such products for human clinical
use until it receives notification from the FDA that FDA agrees with the
Company's assertion of substantial equivalence, a process that can take six to
eighteen months, or longer. In the event that the FDA requests additional
information for the Pre-Market Notification, there could be multiple cycles of
submissions, each involving an additional waiting period, until clearance is
obtained. The FDA also has statutory authority to require clinical or other
study data to support a Pre-Market Notification 510(k).
 
  Where there is no existing legally marketed product "substantially
equivalent" to the Company's product, the Company will be required to seek
marketing approval of its product by the second procedure. This second
procedure, a Pre-Market Approval ("PMA") application, involves a lengthier and
more burdensome procedure, which would likely require clinical studies.
Together with the FDA review of the PMA, this application process may take 3-5
years before commercial marketing can occur, if the PMA is approved. There can
be no assurance that any future product the Company develops which is the
subject to FDA review will be found to have an intended use and
characteristics that would qualify the new test for commercial distribution
for clinical use under 510(k) Pre-Market Notification. Thus, PMAs may be
required for some or all of the Company's future proposed products.
 
  The FDA invariably requires clinical data before approving either a PMA or a
510(k). The FDA is empowered to grant a 510(k) clearance without supporting
clinical data. If clinical studies are necessary for either a PMA approval or
510(k) clearance, the FDA may require the Company to obtain an investigational
device exemption ("IDE"). An IDE normally restricts the transfer of an
investigational device to a limited number of institutions, and use to a
limited number of investigators. Before the approval and/or clearance is
issued, such institution or investigators may receive the Company's
investigational devices only for the purpose of performing the clinical
studies that are to be submitted to the FDA in support of a 510(k) or a PMA
application.
 
  The Company believes that DBT instruments, if any, that it may develop in
the future will be eligible for marketing under a 510(k) Premarket
Notification, if cleared by FDA, but that the substrate would require approval
of a New Drug Application as described in the following section. The Company
believes that clinical studies would be required to obtain FDA approval of the
510(k)/NDA the DBT instrument/substrate, and would be conducted under IDE
approved by FDA. There can be no assurances that FDA will allow the Company to
conduct such clinical studies or that such studies will provide the data
necessary to obtain the approval of the
 
                                      34
<PAGE>
 
510(k)/NDA for any DBT or other product that the Company may develop, or that
FDA will in fact provide the necessary approval of the 510(k)/NDA in a timely
manner, if at all.
 
  In addition, use of the DBT and other diagnostic products developed by the
Company may be subject to regulation under the Comprehensive Laboratory
Improvement Act of 1986 ("CLIA"). Under CLIA, clinical laboratories must be
certified to perform diagnostic tests. Such certification specifies the
highest "complexity level" of tests that the laboratory can perform. The
specific complexity level of a given diagnostic product is determined by
governmental agencies, currently the U.S. Centers for Disease Control. The
Company's ability to successfully market diagnostic products within the U.S.
may depend on its obtaining a complexity level determination that allows the
broadest use. There can be no assurance that such complexity level
determination can be obtained in a timely manner, if at all, and that such
failure will not have a material adverse effect on the Company and its
operations.
 
 Drug Products
 
  Certain products that may be developed by the Company may be classified,
depending on their characteristics, as drugs regulated under the FDCA.
Development of a drug product for use in humans is a multistep process. First,
laboratory and animal testing establishes reasonable safety of the
experimental product for testing in humans and suggests potential efficacy
with respect to a given disease. Once the general investigative plan and
protocols for specific human studies are developed, an investigational new
drug application ("IND") is submitted to the FDA. Under FDA regulations, the
Agency does not approve an IND. Rather, assuming compliance with applicable
requirements, the IND becomes effective, thus allowing a clinical
investigation to commence unless FDA notifies the sponsor to the contrary
within 30 days of receipt of the IND. That approval may come within 30 days of
IND submission but may involve substantial delays if the FDA requests
additional information before approving any clinical testing.
 
  The initial phase of clinical testing (Phase 1) is conducted on a relatively
small number of subjects (e.g., 20-50) to evaluate the pharmacological actions
and side effects of the experimental product in humans and, if possible, to
gain early evidence of effectiveness. Phase 1 studies evaluate various routes,
dosages and schedules of product administration. The demonstration of
diagnostic performance is not required in order to complete such studies
successfully. If acceptable product safety is demonstrated, then Phase 2
studies may be initiated. The Phase 2 studies are designed to evaluate the
effectiveness of the product in the diagnosis of a given disease and,
typically, are well-controlled, closely monitored studies on a relatively
moderate number of patients (e.g., 50-200). The optimal routes, dosages and
schedules of administration, and other matters, are determined in these
studies. If Phase 2 trials are successfully completed, Phase 3 trials will be
commenced.
 
  Phase 3 trials are the larger controlled trials and uncontrolled studies,
often involving hundreds of patients (400-500 or more) that are intended to
gather additional information about safety and effectiveness in order to
demonstrate the overall risk/benefit relationship of the experimental product
and to provide an adequate basis for labeling and marketing approval. It is
not possible to estimate the time in which Phase 1, 2 and 3 studies will be
completed with respect to a given product, although the time period required
is often four to ten years in duration, depending on the clinical protocol
design, endpoints and FDA requirements.
 
  Following the successful completion of these clinical trials, the clinical
evidence that has been accumulated is submitted to the FDA as part of a new
drug application ("NDA"). Approval of the NDA is necessary before a company
may market the product. The approval process can be very lengthy, frequently
taking one to two years, or more, after submission and depends in part upon
the speed of FDA's review of the application and the time required for the
company to provide satisfactory answers or additional clinical or other data
when requested. With any given product, there is no assurance that an NDA will
ever be approved in a timely manner or at all. Failure to obtain such
approvals would prevent the Company from commercializing its products and
would have a material adverse effect on the Company's business. Furthermore,
the process of seeking and obtaining FDA approval for a new product generally
requires substantial funding, and there can be no assurance such funding will
be available.

 cGMPs and Other Controls
 
  The FDA also has extensive regulations concerning manufacturing of regulated
products in accordance with current good manufacturing practices ("cGMPs").
The Company's compliance with cGMPs, including compliance of its third-party
manufacturers, and its ability to ensure the potency, purity and quality of
the drugs and medical devices manufactured, must be documented in the NDAs,
510(k)s and PMAs submitted for the products. Continued compliance with cGMPs
is required to continue to market both drugs and medial devices once they are
approved. Failure to comply with the cGMP regulations or other applicable
legal requirements can lead to federal seizure of violating products,
injunctive relief actions brought by the federal government and potential
criminal investigation and prosecution of the Company and its officers and
employees who are responsible for the activities that lead to the violations.
 
  The Company and the facilities used by it also are required to comply with
environmental and other regulations concerning the operations of and the
materials used by the Company, as well as handling and distribution of
products and waste materials. Failure to ensure compliance with such federal,
state or local laws and regulations could have a material adverse effect on
the Company.
 
  In addition, the manufacture, distribution and export of some of the
Company's current or potential products and technology may be subject to
governmental controls pertaining to materials and technology that might have
been used for military, nuclear power, or nuclear weapons purposes. These
controls include, in certain cases, export license requirements or other
restrictions. There can be no assurances that the Company will be able to
obtain or maintain such licenses, or that the failure to obtain or maintain
such licenses, or comply with other restrictions that might be placed on such
manufacturing and exports, will not have a material adverse effect on the
Company and its operations.
 
 Export and Environmental Controls
 
  Certain of the Company's products and technology, particularly those having
potential nuclear energy or military applications, such as DZ and related
technology, are subject to stringent controls over their manufacture, use,
distribution, dissemination and export. In many cases, such activities may
require approvals or licenses from various U.S. and foreign governmental
agencies, and compliance with substantial regulatory controls. Such approvals
can be difficult to obtain and maintain and may not be obtainable from certain
countries. Furthermore, such approvals or licenses may be restricted or
terminated because of changes in laws, regulations, policies governing those
approvals and licenses, or changes in the political or other matters in the
countries granting such approvals or licenses to which the Company's products
and technology would be exported. Likewise, certain current and potential
operations of the Company may necessitate submitting registrations or
notifications to federal and state regulatory authorities responsible for
environmental and related matters, including the U.S. Environmental Protection
Agency ("EPA") and complying with stringent controls pertaining to the
handling and distribution of the Company's products and operations, including
under certain conditions obtaining governmental approvals and licenses, either
of which may be subject to significant restrictions. Violation of any of these
regulatory controls may subject the Company to significant administrative
civil and criminal penalties, including loss of its approvals and licenses, or
the imposition of additional restrictions on the Company's operations.
 
  There can be no assurances that the Company will be able to obtain and
maintain the approvals or licenses necessary to successfully market its
products and technology, or that it will be able to comply with applicable
laws and regulations. Any such failure to obtain such licenses or approvals,
where required, and comply with such laws and regulations may materially and
adversely affect the business, financial condition and results of operations
of the Company.
 
 Regulation of Non-Medical Chemical Products
 
  The import, export, handling, transportation, sale, storage and other
activities undertaken in connection with the Company's non-medical products
are subject, or potentially subject, to substantial federal, state, local and
 
                                      36
<PAGE>
 
foreign government controls pertaining to hazardous chemical and chemical
wastes, import export controls and other matters. These regulations are
complex, pervasive and evolving. The Company's ability to effect and maintain
compliance with these controls is important to its commercial success.
 
  With respect to transportation of its products, the Company relies on
Russian and U.S. freight carriers to handle and deliver all its shipments, and
utilizes domestic overnight courier services for shipments to its customers.
These carriers must comply with Department of Transportation ("DOT")
regulations in the shipping and packaging of the stable isotope chemicals. The
Company must also comply with DOT regulations when packaging material kept in
inventory for domestic shipment. As required under federal and state law, the
Company has prepared Material Safety Data Sheets ("MSDS"), which are enclosed
with each product shipment. The Company must periodically update its MSDS
sheets based on new literature reports. The Company cannot assure that its
MSDS sheets will continue to be in compliance with applicable requirements.
   
  The shipments received at the Company's Columbia, Maryland facility are
subject to federal and Maryland regulations pertaining hazardous chemicals and
hazardous waste disposal. These shipments are stored in an area of the
facility designated for such materials. Currently, the Company is considered a
small quantity generator of hazardous waste and will rely on certified haulers
to dispose of its minimal amounts of hazardous waste. The Company believes it
is in compliance in all material respects with applicable federal and state
environmental regulatory requirements. Should the levels of hazardous waste
increase as its inventory and handling operations increase in volume, then it
would have to comply with Environmental Protection Agency ("EPA") requirements
and obtain an EPA ID number, which are costly and require an increased
investment of personnel and money. The Company has no experience in this area
of compliance and would have to rely on outside consultants or hire additional
employees with pertinent experience and training. Potentially, if
substantially larger inventories of hazardous chemicals must be maintained at
the Maryland facility, the Company might have to move to new facilities in
order to meet EPA requirements for the storage of hazardous chemicals.     
 
  The shipments from Russian manufacturing sources now enter the U.S. duty
(without tariff) free; however, there can be no assurance that such duty-free
importation will continue. If the shipments are subject to tariff, the Company
cannot assure that it will be able to sell the imported products will be
commercially viable because of these increased tariff costs.
 
  The Nuclear Regulatory Commission ("NRC") has authority to regulate
importation and exports of deuterium containing chemicals whose ratio of
deuterium atoms to hydrogen atoms exceed 1:5000. At present, the deuterium
containing compounds which the Company imports do not require any special
licenses or importation authorization. There can be no assurances that the NRC
will continue these policies. The NRC regulates exports of deuterium
containing chemicals under general license. The Company will not be able to
ship these chemicals to certain countries which require a special license for
such shipments; none of these countries represent significant current or
expected future markets for the Company. In addition, certain technology or
products that the Company is or may in the future develop, may be subject to
other government controls pertaining to armaments, including the need to
obtain special licenses for exports. The imposition of such controls may
impair the ability to broadly market such products.
 
PRODUCT LIABILITY AND INSURANCE
 
  The Company's business exposes it to potentially substantial product,
environmental, occupational and other liability risks which are inherent in
product research and development, manufacturing, marketing distribution and
use of its products and operations, including, but not limited to, products
used in nuclear power plants and medical device products. The Company
currently does not have product liability insurance, but may seek such
insurance before it begins commercial distribution of medical or other
products that it may develop. There can be no assurance that adequate or
necessary insurance coverage will be available at an acceptable cost, if at
all, or that even if such insurance were obtained, a product liability or
other claim would not materially and adversely affect the business or
financial condition of the Company. See "Risk Factors--Product Liability;
Minimal Insurance Coverage."
 
                                      37
<PAGE>
 
  The terms of the Company's agreements with its customers provide that
liability to nuclear power plant utilities is limited to the Company's
standard warranty to replace non-conforming product, and liability for
consequential damages caused by the improper use of the Company's products is
limited by contractual terms. Nevertheless, one or more third parties could
bring an action against the Company based on product liability, breach of
warranty or other claims, and, there can be no assurance that the foregoing
contract clauses would effectively limit the Company's liability in any such
actions.
 
EMPLOYEES
 
  As of August 15, 1996, the Company had 10 full-time employees, of whom 2
have Ph.D.'s and 4 have advanced degrees in chemistry, engineering, and
related fields. Approximately 3 employees are involved in research and product
development, 2 in manufacturing and sourcing, and 5 in business development
and administration, but such employees' responsibilities may also encompass
areas other than their primary area of responsibility.
 
  The Company plans to recruit a Vice President to manage and lead its
development of the planned electronic and optical materials business and a
General Manager plus additional personnel as may be required to staff its
intended SILC laboratory and business expansion.
 
  The Company considers its relations with its employees to be good. None of
the Company's employees are covered by a collective bargaining agreement.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any legal proceedings.
 
FACILITIES
   
  The Company leases 2,500 square feet of administrative and technical space
in San Jose, California. The lease expires January 1999. The Company leases
641 square feet for an administrative office in Columbia, Maryland. This lease
expires in December 1997. The Company leases office and laboratory space on a
month-to-month basis at Moscow State University where it performs its research
on isotope separation.

(1) Mr. Alexander's and Mr. Rubizhevsky's options are exercisable in full at
    the date of grant, but are subject to a right of repurchase in favor of
    the Company upon the employment termination of the optionee, which right
    lapses over a three-year period with respect to 20% of the shares subject
    to the option after one year from the grant date, an additional 8.33% of
    the shares subject to the option each three month period from January 1997
    through January 1998, and an additional 11.66% of the shares subject to
    the option for each three month period from February 1998 through January
    1999.
 
(2) The exercise price for these options represents 110% of the estimated fair
    market value of the underlying Common Stock, as determined by the Board as
    of the date of grant.
   
  In September 1996, Mr. Alexander and Mr. Rubizhevsky each exercised his
option to acquire 108,853 shares at $1.52 per share. In payment of the
exercise price, the Company accepted a full recourse promissory note from each
officer in the principal amount of approximately $165,000. The principal bears
interest at the minimum applicable federal rate, which is payable in annual
installments over the term of the note. All accrued and unpaid interest and
all principal is due five years after the exercise date. The purchased shares
have been pledged to secure repayment of the loan. Upon a sale of any shares,
a portion of the net proceeds equal to the exercise price per share of the
shares sold will be used to repay the loan. See "--Certain Transactions."     
   
  No stock options were exercised during fiscal 1996 by any Named Person.     
 
DIRECTOR COMPENSATION
 
  Directors of the Company do not receive cash compensation for their services
as directors but are reimbursed for their reasonable expenses in attending
meetings of the Board. Directors are eligible to participate in the Executives
Plan and Incentive Plan. See "--Employee Benefit Plans."
 
EMPLOYMENT AND CONSULTING AGREEMENTS
 
  The Company has employment agreements dated January 1, 1996 with James E.
Alexander and Boris Rubizhevsky. Effective upon the closing of this offering,
those agreements will be amended by new employment agreements. The new
agreements become effective upon the closing of this offering. The agreements
have a term of four years and provide for annual salaries of $200,000 and
$180,000, respectively. Either the Company or the officer may terminate the
agreement at any time upon notice to the other party. The agreements provide
that upon a termination of employment other than for cause (as defined in the
agreements), the officer is entitled to severance compensation of 18 months of
his salary, paid at the same time as salary payments, and in addition all
outstanding stock options held by the officer will be accelerated and will
become exercisable in full and the Company's right of repurchase will
terminate with respect to such shares. The agreements provide for similar
accelerated vesting of outstanding stock options, upon a change in control of
the Company. The Company has also entered into an agreement with Paul Catuna,
the Company's Chief Financial Officer, providing for the grant of a stock
option to acquire 40,000 shares of Common Stock at an exercise price equal to
110% of the IPO Price Per Share. The shares subject to the option are subject
to a right of repurchase that lapses based upon the achievement of certain
financial requirements.
   
  The Company has also entered into a number of employment agreements with
certain of its officers and employees, including Daniel J. Grady, Martin
Laurent, Joe Friscia, Paul J. Catuna and Jacques Delente. The terms of these
agreements are similar in material respects except for the compensation
payable to such officers. The agreements have an indefinite term and provide
for at-will employment, terminable at any time by either     
 
                                      42
<PAGE>
 
party. The agreements provide for a rate of annual compensation, which the
Company will review annually. Under the agreements, the employees are entitled
to participate in the Company's standard plans and policies. The agreements
also include customary confidentiality and invention assignment provisions.
   
  The Company has a consulting agreement with Donald P. Hateley pursuant to
which Mr. Hateley will provide financial, public relations and investor
relations services for a period of six months after the date of this offering.
The agreement provides for payments to Mr. Hateley totalling $180,000, of
which approximately $120,000 is expected to be paid and $90,000 is expected to
be expensed in the fiscal quarter during which the offering becomes effective.
Mr. Hateley is entitled to receive additional compensation if the Warrants
issued in this offering are exercised. A law firm, of which Mr. Hateley is of
counsel holds warrants to purchase 127,721 shares of Common Stock, exercisable
at any time until September 2000 at an exercise price of $1.38 per share,
received approximately $54,000 for legal services during fiscal 1996 and the
first three months of fiscal 1997. The Company has agreed to file a
registration statement after the effectiveness of this offering covering the
resale of the shares issuable upon exercise of the warrants.     
 
EMPLOYEE BENEFIT PLANS
 
  The Company currently has a 1996 Stock Option Plan (the "Existing Plan").
After the closing of this offering, no further options will be granted under
the Existing Plan, and future awards will be granted pursuant to the Company's
1996 Executives Equity Incentive Plan (the "Executives Plan") and the 1996
Equity Incentive Plan (the "Incentive Plan"). The terms of the Existing Plan
are, in material respects, similar to the terms of the Executives Plan and the
Incentive Plan. The Executives Plan and Incentive Plan are sometimes referred
to collectively as the "Plans." The Company's shareholders approved these
Plans in October 1996, and the Plans will become effective upon the effective
date of this offering.
   
  1996 Executives Plan and Incentive Plan. In November 1996, the Board adopted
the Executives Plan and Incentive Plan. A total of 225,000 shares of Common
Stock and 50,000 shares of Common Stock are reserved for issuance under the
Executives Plan and the Incentive Plan, respectively. Except for the number of
shares reserved under each Plan, the terms of vesting of options or other
awards upon a Change of Control (as defined below) and as otherwise set forth
below, the Executives Plan and the Incentive Plan are similar in material
respects. Under each of the Executives Plan and the Incentive Plan, shares
that (i) are subject to an option under that Plan but cease to be subject to
such option for any reason other than exercise of such option, (ii) are
awarded under that Plan but are forfeited or are repurchased by the Company at
the original issue price or (iii) are subject to an award that otherwise
terminates without shares being issued will, in each case, be redesignated as
available for grant or issuance under that Plan. Both Plans will terminate in
September 2006, unless terminated earlier in accordance with their provisions.
       
  The Executives Plan and Incentive Plan provide for grants of stock options,
stock bonuses and awards of restricted stock by the Company to its officers,
directors who are employees of the Company, other employees, consultants,
independent contractors and advisors. No person will be eligible to receive
awards covering more than 200,000 shares in any calendar year under the
Executives Plan, and no person will be eligible to receive more than 50,000
shares in any calendar year pursuant to grants under the Incentive Plan. The
Plans will be administered by the Compensation Committee of the Board (the
administrator referred to as the "Committee"). The Plans permit the Committee
to grant options that are either incentive stock options, as defined in
Section 422 of the Code or nonqualified stock options, on terms (including the
exercise price, which may not be less than 85% of the fair market value of the
Common Stock, and the vesting schedule) determined by the Committee, subject
to certain statutory and other limitations in the Plans and certain
limitations imposed by state blue sky authorities. In addition to, or in
tandem with, awards of stock options, the Committee may grant participants
restricted stock awards to purchase Common Stock for not less than 85% of its
fair market value at the time of grant. The other terms of such restricted
stock awards may be determined by the Committee. The Committee may also grant
stock bonus awards of Common Stock either in addition to, or in tandem with,
other awards under the Plans, under such terms, conditions and restrictions as
the Committee may determine. Under the Plans, stock bonuses may be awarded for
the satisfaction of performance goals established in advance. In the event of
a     
 
                                      43
<PAGE>
 
   
dissolution, merger, consolidation or similar corporate transaction (each such
transaction a "Change of Control") (other than a merger into a parent, wholly
owned subsidiary or a reincorporation, in each event without substantial
change of equity interest), outstanding awards may be assumed, converted,
replaced or substituted by the successor corporation, which assumption,
conversion, replacement or substitution will be binding on all participants in
the Plan. If such successor corporation does not assume or substitute awards
under the Incentive Plan, such awards will expire on the consummation of such
Change in Control, on such terms and conditions as the Board determines.     
   
  401(k) Plan. The Board has adopted the Isonics Corporation 401(k) Savings &
Retirement Plan (the "401(k) Plan"), a defined contribution profit-sharing
plan intended to qualify under Section 401 of the Code. The shareholders of
the Company approved the 401(k) Plan in November 1996. Under the 401(k) Plan,
a participating employee can make pre-tax contributions, subject to
limitations under the Code, of a percentage (not to exceed 15%) of his or her
total compensation. Employee contributions and the investment earnings thereon
are fully vested at all times. The Company may make matching contributions for
the benefit of eligible participating employees.     
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS AND LIMITATION OF LIABILITY
 
  The Company's Restated Articles of Incorporation (the "Restated Articles")
include a provision that eliminates to the fullest extent permitted by law the
personal liability of its directors to the Company and its shareholders for
monetary damages for breach of the directors fiduciary duties. This limitation
has no effect on a director's liability (i) for acts or omissions that involve
intentional misconduct or a knowing and culpable violation of law, (ii) for
acts or omissions that a director believes to be contrary to the best
interests of the Company or its shareholders or that involved the absence of
good faith on the part of the director, (iii) for any transaction from which
the director derived an improper personal benefit, (iv) for acts or omissions
that show a reckless disregard for the director's duty to the Company or its
shareholders in circumstances in which the director was aware, or should have
been aware, in the ordinary course of performing a director's duties, of a
risk of serious injury to the Company or its shareholders, (v) for acts or
omissions that constitute an unexcused pattern of inattention that amounts to
an abdication of the director's duty to the Company or its shareholders, (vi)
under Section 310 of the California Corporations Code (the "California Code")
concerning contracts or transactions between the Company and a director or
(vii) under Section 316 of the California Code concerning directors' liability
for improper dividends, loans and guarantees. The provision does not extend to
acts or omissions of a director in his or her capacity as an officer. Further,
the provision will not affect the availability of injunctions and other
equitable remedies available to the Company's shareholders for any violation
of a director's fiduciary duty to the Company or its shareholders.
 
  The Restated Articles further authorize the Company to indemnify its agents
(as defined in Section 317(a) of the Code, which includes directors and
officers) through Bylaw provisions, agreements with agents, votes of
shareholders or disinterested directors or otherwise, to the fullest extent
permissible under California law. Pursuant to this provision, the Company's
Bylaws provide for indemnification of directors and officers. The Bylaws also
permit the Company to enter into indemnity agreements with individual
directors, officers, employees and other agents. The Company has entered into
such agreements with its directors and executive officers effective upon the
closing of this offering. These agreements, together with the Company's Bylaws
and Restated Articles, may require the Company, among other things, to
indemnify directors or officers against certain liabilities that may arise by
reason of their status or service as directors (other than liabilities
resulting from willful misconduct of a culpable nature), to advance expenses
to them as they are incurred (provided that they undertake to repay the amount
advanced if it is ultimately determined by a court that they are not entitled
to indemnification), and to obtain and maintain directors and officers
insurance if available on reasonable terms. Section 317 of the California
Code, the Company's Bylaws and the indemnity agreements provide for the
indemnification of officers, directors and other corporate agents in terms
sufficiently broad to indemnify such persons, under certain circumstances, for
liabilities (including reimbursement of expenses incurred) arising under the
Securities Act. At present, there is no pending litigation or proceeding
involving a director, officer or
 
                                      44
<PAGE>
 
employee of the Company regarding which indemnification is sought, nor is the
Company aware of any threatened litigation that may result in claims for
indemnification.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.

                             CERTAIN TRANSACTIONS
 
  Since May 1, 1994, there has not been, nor is there currently proposed, any
transaction or series of similar transactions to which the Company was or is
to be a party in which the amount involved exceeds $60,000 and in which any
director, executive officer, holder of more than 5% of the Common Stock, or
any member of the immediate family of any such person had or will have a
direct or indirect material interest other than compensation arrangements, see
"Management," and as described below.
   
  In connection with the Placement, Placement Notes in an aggregate principal
amount of $370,000 were issued to Lindsay Gardner, a director of the Company,
one employee of the Company and four affiliates of directors or officers of
the Company at a discount totalling approximately $41,000 and otherwise on the
same terms as the other Private Investors. In addition, DayStar Partners, an
entity of which Larry J. Wells, a director of the Company, is an affiliate,
acquired $200,000 principal amount of Placement Notes and Placement Warrants
to acquire approximately 41,745 shares of Common Stock on the same terms as
other Private Investors, and the Company entered into a consulting agreement
with that entity, pursuant to which the Company paid the entity $85,000.
Pursuant to the consulting agreement, DayStar Partners advised the Company
concerning the Placement and following completion of this offering has
consulted with the Company as requested concerning financing matters and
acquisition opportunities. See "Capitalization--Recent Financing
Transactions."     
   
  In September 1996, in part in order to allow the Company to establish a pool
of shares available for future awards pursuant to the Plans in amounts that
comply with the guidelines established by certain state blue sky authorities,
Mr. Alexander and Mr. Rubizhevsky exercised stock options to acquire 108,853
and 108,853 shares, respectively, of Common Stock at an exercise price of
$1.52 per share. The exercise price for the shares was paid by means of a loan
from the Company in the principal amount of the exercise price. The purchased
shares are pledged as collateral for the loans pursuant to a pledge agreement.
The loans bear interest at an annual rate equal to the minimum applicable
federal rate, and interest is payable annually. Principal and accrued but
unpaid interest is due five years from the date of the note. For each
optionee, until the note has been paid in full, upon any sale of such option
shares by the optionee a portion of the sales proceeds equal to the exercise
price per share of the shares sold will be used to pay amounts owed under the
note. In addition, the Company has agreed to loan to such officers, pursuant
to a five-year note with interest at the minimum applicable federal rate, an
amount equal to the federal and state tax liability incurred by them as a
result of exercising such options, and to pay compensation to such officers
equal to the amount of interest payable under the loans and the amount of
taxes payable as a result of such compensation.     
 
  The predecessor entity to the Company was a general partnership. At the time
of incorporation in 1993, Mr. Alexander and Mr. Rubizhevsky exchanged their
partnership interests for 758,345 and 620,465 shares of Common Stock,
respectively.
 
  The Company is also a party to several employment and consulting agreements.
See "Management--Employment and Consulting Agreements."

                         DESCRIPTION OF CAPITAL STOCK
   
  Upon the closing of this offering, the authorized capital stock of the
Company will consist of 20,000,000 shares of Common Stock and 10,000,000
shares of Preferred Stock. As of October 1, 1996, there were outstanding
1,814,796 shares of Common Stock held of record by five shareholders, 6,250
shares of Class A Non-Voting Preferred Stock which will convert into 96,315
shares of Common Stock upon the closing of this offering, options and warrants
to purchase 646,268 shares of Common Stock, which included options to purchase
272,134 shares of Common Stock issued under the Company's employee benefit
plan and warrants to purchase 414,134 shares of Common Stock associated with
the Placement.     
 
COMMON STOCK
   
  Subject to preferences that may be applicable to any Preferred Stock
outstanding at the time, the holders of outstanding shares of Common Stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the Board of Directors may from time to time
determine. Each shareholder is entitled to one vote for each share of Common
Stock held on all matters submitted to a vote of shareholders. Cumulative
voting for the election of directors is specifically authorized by the Bylaws.
Under cumulative voting for the election of directors, upon a proper and
timely request by a shareholder, each shareholder is entitled to cast a number
of votes equal to the number of shares held multiplied by the number of
directors to be elected. The votes may be cast for one or more candidates.
Thus, under cumulative voting, a majority of the outstanding shares will not
necessarily be able to elect all of the directors, and minority shareholders
may be entitled to greater voting power with respect to election of directors
than if cumulative voting did not apply. The Company's bylaws provide that so
long as the Company is a "listed company" as defined by applicable California
law, there will not be cumulative voting in connection with the election of
directors. Upon the closing of this offering, however, the Company will not be
a listed company as so defined, and therefore cumulative voting will continue
to apply in connection with the election of directors. The Common Stock is not
entitled to preemptive rights and is not subject to conversion or redemption.
Upon liquidation, dissolution or winding up of the Company, the remaining
assets legally available for distribution to shareholders, after payment of
claims or creditors and payment of any liquidation preferences, if any, on
outstanding Preferred Stock, are distributable ratably among the holders of
the Common Stock and any participating Preferred Stock outstanding at that
time. Each outstanding share of Common Stock is, and all shares of Common
Stock to be outstanding upon completion of this offering will be, fully paid
and nonassessable.     
 
PREFERRED STOCK
 
  The Board of Directors is authorized, subject to any limitations prescribed
by California law, to provide for the issuance of shares of Preferred Stock in
one or more series, to establish from time to time the number of shares to be
included in each such series, to fix the rights, preferences and privileges of
the shares of each unissued series and any qualifications, limitations or
restrictions thereon, and to increase or decrease the number of shares of any
such series (but not below the number of shares of such series then
outstanding), without any further vote or action by the shareholders. The
Board of Directors may authorize the issuance of Preferred Stock with voting
or conversion rights that could adversely affect the voting power or other
rights of the holders of Common Stock. Thus, the issuance of Preferred Stock
may have the effect of delaying, deferring or preventing a change in control
of the Company.
 
  The Company has no current plans to issue any shares of Preferred Stock.

OTHER SECURITIES
 
 Representatives' Warrants
 
  In connection with this offering, the Company has authorized the issuance to
the Representatives of 85,000 Representatives' Warrants and has reserved
170,000 shares of Common Stock for issuance upon exercise of the
Representatives' Warrants and the warrants issuable upon exercise of the
Representatives' Warrants. Each Representatives' Warrant will entitle the
holder to purchase one share of Common Stock at a price of $   per share,
which is 120% of the IPO Price Per Share, and, upon payment of $  , which is
120% of the initial public offering price of the Warrants, to acquire one
Warrant. Each such Warrant will entitle the holder to purchase one share of
Common Stock at a price of $   per share, which is 150% of the IPO Price Per
Share. The Representatives' Warrants will, subject to certain conditions, be
exercisable any time until the fifth anniversary of the date of this
Prospectus. See "Underwriting."
 
  The Representatives' Warrants also contain provisions to protect the holder
against dilution by adjustment of the exercise price in certain events, such
as stock dividends and distributions, stock splits and recapitalizations. The
Company is not required to issue fractional shares upon the exercise of a
Representatives' Warrant, and the holder thereof will not possess any rights
as a shareholder of the Company until such holder exercises the
Representatives' Warrants. The other terms of the Representatives' Warrants
are similar in material respects to the Warrants, except that the
Representatives' Warrants (and the warrants included therein) will not be
publicly tradeable and will not be redeemable by the Company.
 
  The foregoing discussion of certain terms and provisions of the
Representatives' Warrants is qualified in its entirety by reference to the
detailed provisions of the Representatives' Warrant Agreement, the form of
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part.
 
 The Warrants
 
  The following is a brief summary of certain provisions of the Warrants.
Reference is made to the actual text of the Warrant Agreement between the
Company and Continental Stock Transfer & Trust Company (the "Warrant Agent"),
a copy of which has been filed as an exhibit to the Registration Statement of
which this Prospectus is a part, for a more complete description of the
Warrants.
 
  Exercise Price and Terms. Each Warrant entitles the registered holder
thereof to purchase, at any time during the five year period commencing on the
date of this Prospectus, one share of Common Stock at a price of $   per share
(150% of the IPO Price Per Share), subject to adjustment in accordance with
the anti-dilution and other provisions referred to below. The holder of any
Warrant may exercise such Warrant by surrendering the certificate representing
the Warrant to the Warrant Agent, with the subscription form thereon properly
completed and executed, together with payment of the exercise price. No
fractional shares will be issued upon the exercise of the Warrants.
 
  Adjustments. The exercise price and the number of shares of Common Stock
purchasable upon the exercise of the Warrants are subject to adjustment upon
the occurrence of certain events, including stock dividends, stock splits,
combinations or reclassifications of the Common Stock. Additionally, an
adjustment would be made in the case of an exchange of Common Stock,
consolidation or merger of the Company with or into another corporation (other
than a consolidation or merger in which the Company is the surviving
corporation) or sale of all or substantially all of the assets of the Company,
in order to enable holders to acquire the kind and number of shares of stock
or other securities or property receivable in such event by a holder of the
number of shares of Common Stock that might have been purchased upon the
exercise of the Warrant.
 
  Redemption Provisions. The Company may redeem the Warrants in whole or in
part, at any time upon at least 30 days prior written notice to the registered
holders thereof, at a price of $0.05 per Warrant, if the closing price of the
Common Stock as reported on the Nasdaq SmallCap Market equals or exceeds 200%
of the IPO Price Per Share (subject to adjustment for stock dividends, stock
splits, combinations or reclassifications of the
 
                                      49
<PAGE>
 
   
Common Stock), for at least 20 consecutive trading days ending immediately
before the notice of redemption. If the Company exercises the right to redeem
the Warrants, the Warrants will be exercisable until the close of business on
the business day immediately preceding the date for redemption fixed in such
notice. If any Warrant called for redemption is not exercised by such time, it
will cease to be exercisable and the holder will be entitled only to the
redemption price.     
 
  Transfer, Exchange and Exercise. The Warrants are in registered form and,
subject to the Company's redemption rights therefor, may be presented to the
Warrant Agent for transfer, exchange or exercise at any time on or before
their expiration date five years from the date of this Prospectus, at which
time the Warrants become wholly void and of no value. If a market for the
Warrants develops, the holder may sell the Warrants instead of exercising
them. There can be no assurance, however, that a market for the Warrants will
develop or continue.
 
  Modification of Warrants. The Company and the Warrant Agent may make such
modifications to the Warrants as they deem necessary and desirable that do not
adversely affect the interests of the Warrant holders. The Company may, in its
sole discretion, lower the exercise price of the Warrants for a period of not
less than 30 days on not less than 30 days' prior written notice to the
Warrant holders and the Representatives. Modification of the number of
securities purchasable upon the exercise of any Warrant, the exercise price
(except as described in the preceding sentence) and the expiration date with
respect to any Warrant requires the consent of holders of two-thirds of the
then outstanding Warrants. Except as described above, no other modifications
may be made to the Warrants, without the consent of holders of two-thirds of
the then outstanding Warrants.
   
  The Warrants are not exercisable unless, at the time of the exercise, the
Company has a current prospectus covering the shares of Common Stock issuable
upon exercise of the Warrants, and such shares have been registered, qualified
or deemed to be exempt under the securities laws of the state of residence of
the exercising holder of the Warrants. Although the Company will use all
reasonable efforts to have all of the shares of Common Stock issuable upon
exercise of the Warrants registered or qualified on or before the exercise
date and to maintain a current prospectus relating thereto until the
expiration of the Warrants, there can be no assurance that it will be able to
do so.     
 
  The Warrants are separately transferable immediately upon issuance. Although
the Warrants will not knowingly be sold to purchasers in jurisdictions in
which the Warrants are not registered or otherwise qualified for sale,
purchasers may buy Warrants in the aftermarket or may move to jurisdictions in
which the shares of Common Stock underlying the Warrants are not so registered
or qualified during the period that Warrants are exercisable. In this event,
the Company would be unable to issue shares to those persons desiring to
exercise their Warrants, and those persons would have no choice but to attempt
to sell their Warrants in a jurisdiction where such sale is permissible or
allow them to expire unexercised.
 
  For the life of the Representatives' Warrants, the Warrants, and the
Placement Warrants, respectively, the holders thereof have the opportunity to
profit from a rise in the market price of the Common Stock without assuming
the risk of ownership of the shares of Common Stock issuable upon the exercise
of such warrants, with the resulting potential for dilution in the interest of
the Company's shareholders by reason of the likely exercise of such warrants
at a time when the exercise price is less than the market price for the Common
Stock. Further, the terms on which the Company could obtain additional capital
during the life of such warrants may be adversely affected. The holders of
such warrants may be expected to exercise the rights thereunder at a time when
the Company would, in all likelihood, be able to obtain any needed capital
through an offering of Common Stock on terms more favorable than those
provided for by such warrants.

  The following discussion sets forth certain federal income tax consequences,
under current law, relating to the purchase and ownership of the Units, the
Common Stock and the Warrants constituting the Units. The Company has not
requested and does not intend to request a ruling from the Internal Revenue
Service or a tax opinion from its counsel on any tax aspect of the offering.
This tax discussion does not purport to be a complete
 
                                      50
<PAGE>
 
analysis or list of all potential federal income tax consequences of the
purchase, ownership and sale of the Common Stock or Warrants. The discussion
does not address the tax treatment for certain unique taxpayers, such as
insurance companies, tax exempt organizations, financial institutions, and
dealers in securities which may be subject to special rules not discussed
herein. This discussion presents no analysis of the tax attributes of the
Company either before or after this offering. PROSPECTIVE PURCHASERS OF THE
UNITS SHOULD CONSULT THEIR OWN TAX ADVISERS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND SALE OF SUCH SECURITIES
AND THE APPLICABILITY OF FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.
 
  An investor must allocate the cost of each Unit between its two elements
(one Share and one Warrant to purchase one share of Common Stock) in
accordance with their relative fair market values at the time of issuance. The
portion of the aggregate cost allocated to each element will constitute the
investor's initial federal income tax basis for that element.
 
  No gain or loss will be recognized by a holder of a Warrant held for
investment on the holder's purchase of Common Stock for cash upon exercise of
the Warrant. The adjusted tax basis of the Common Stock so acquired will be
equal to the tax basis of the Warrant plus the exercise price. The holding
period of the Common Stock acquired upon the exercise of the Warrant will
begin on the date the Warrant is exercised and the Common Stock is purchased.
 
  The sale of a share of Common Stock or the sale of a Warrant will result in
the recognition of gain or loss to the holder in an amount equal to the
difference between the amount realized (generally the cash and the fair market
value of any other property received) and the holder's adjusted tax basis for
the property sold. The sale of Common Stock will result in capital gain or
loss, provided the Common Stock is a capital asset in the hands of the holder.
The sale of a Warrant (other than a sale to the Company) will also result in a
capital gain or loss, provided the Warrant is a capital asset in the hands of
the holder and the Common Stock underlying the Warrant would be a capital
asset to the holder if acquired by the holder. Such capital gain or loss will
be long-term capital gain or loss if the Common Stock or Warrant being sold or
exchanged has been held for more than one year at the time of such sale or
exchange.
 
  If the repurchase of a Warrant by the Company is treated as a sale or
exchange of a capital asset, any gain or loss recognized on the transaction
will be capital gain or loss and will be long-term capital gain or loss if the
holding period of the Warrant exceeds one year at the time of repurchase.
However, it is unclear whether the repurchase of a Warrant by the Company will
be treated as the sale or exchange of a capital asset, and if such repurchase
is not treated as the sale or exchange of a capital asset, the holder of a
Warrant could potentially recognize ordinary income on such repurchase because
of a constructive distribution recharacterization.
 
  Long-term capital gains of individuals, trusts and estates are currently
taxed at a maximum rate of 28%, while ordinary income is currently taxed at a
maximum rate of 39.6%. Section 1202 of the Code in certain circumstances
allows certain noncorporate taxpayers to exclude from income one-half of the
gain (up to certain limits) from the sale or exchange of "qualified small
business stock" held for more than five years. In addition, 25% of such gain
(up to certain limits) is excluded for alternative minimum tax purposes. In
order for stock to be "qualified small business stock," the issuer of the
stock must meet certain requirements, some of which apply to the period after
the stock is issued. Consequently, it is unclear whether the Common Stock
acquired upon exercise of a Warrant will qualify as qualified small business
stock.
 
  Under Section 305 of the Code, certain actual or constructive distributions
of stock (including warrants to purchase stock) with respect to such stock (or
warrants) may be taxable to the shareholders (or Warrant holders) of the
Company. Adjustments in the exercise price of the Warrants, or the number of
shares purchasable upon exercise of the Warrants, in each case made pursuant
to the anti-dilution provisions of the Warrants, among other things, may
result in a distribution which is taxable as a dividend to the holders of
Warrants. Distributions may be taxed as ordinary dividend income, return of
capital, or gain from the sale or exchange of stock, depending on the earnings
and profits of the Company and the tax basis of each of its shareholders or
Warrant holders.
 
                                      51
<PAGE>
 
  A Warrant that expires unexercised will be deemed to have been sold or
exchanged for no consideration on the expiration date. The holder of an
expired Warrant would recognize loss to the extent of the holder's basis in
that Warrant. Any loss to the holder of an expired Warrant will be a capital
loss if the Warrant was held as a capital asset and if the Common Stock
underlying the Warrant would have been a capital asset had such Warrant been
exercised. Any capital loss will be long-term if the holding period of the
Warrant exceeds one year when it expires. The use of capital losses to offset
ordinary income is strictly limited for noncorporate shareholders and
prohibited for corporate shareholders.
 
  No gain or loss will be recognized by the Company upon the acquisition,
exercise or expiration of any Warrants.
 
REGISTRATION RIGHTS
 
  In connection with the Placement, the Company agreed to file a registration
statement no later than nine months after the date of this Prospectus to
register the resale of the Placement Shares. Issuable upon exercise of the
Placement Warrants. The Company has also agreed to keep such a registration
statement effective until such shares have been sold or until such shares can
be sold without restrictions pursuant to Rule 144. If such registration
statement does not remain effective, then the Private Investors have certain
additional demand registration rights. In addition, the Private Investors have
piggyback registration rights to require the Company to include the Placement
Shares in registration statements filed by the Company registering Common
Stock under the Securities Act, either for its own account or for the account
of any other stockholder. The Company has also agreed to register the shares
of Common Stock issuable upon exercise of a warrant granted to a law firm. See
"Management--Employment and Consulting Agreements."
 
  As part of the Registration Statement of which this Prospectus forms a part,
the Company has registered the Warrants and the shares of Common Stock
obtainable upon exercise of the Representatives' Warrants (including shares
obtainable upon exercise of the Warrants included therein). The holders of the
Representatives' Warrants have the right to require the Company to file a
registration statement on two separate occasions, commencing one year after
the date of this Prospectus, to register the resale of the shares of Common
Stock issuable upon exercise of the Representatives' Warrants and the warrants
included therein. The Company is required to bear all registration expenses,
other than underwriting discounts and selling commissions, incurred in
connection with the first such registration of the shares underlying
Representatives' Warrants, and the second registration is at the expense of
the Representatives.
 
  These registration rights could result in substantial future expense to the
Company and could adversely affect the Company's ability to complete future
equity or debt financings. Furthermore, the registration and sale of Common
Stock held by or issuable to the holders of registration rights, or even the
potential of such sales, could have an adverse effect on the market price of
the Common Stock or Warrants.
 
TRANSFER AGENT AND REGISTRAR AND WARRANT AGENT
 
  The Transfer Agent and Registrar for the Company's Common Stock and the
Warrant Agent for the Warrants is Continental Stock Transfer & Trust Company.
 
LISTING
   
  The Company has applied to list the Common Stock and Warrants on the Nasdaq
Service SmallCap Market under the trading symbols "ISNX" and "ISNXW,"

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no market for the Common Stock.
Future sales of substantial amounts of Common Stock in the public market could
adversely affect market prices prevailing from time to time.
   
  Upon completion of this offering, and assuming the conversion of the
outstanding preferred stock and no exercises of options or warrants after
October 1, 1996, the Company will have outstanding approximately 2,761,111
shares of Common Stock. Of these shares, the 850,000 shares sold in this
offering and the shares obtainable upon exercise of the Warrants, if and when
such Warrants are exercised, will be freely tradeable without restriction
under the Securities Act, unless purchased by "affiliates" of the Company as
that term is defined in Rule 144 under the Securities Act. The remaining
1,911,111 shares of Common Stock held by existing shareholders were issued and
sold by the Company in reliance on exemptions from the registration
requirements of the Securities Act. These shares may be sold in the public
market only if registered or sold pursuant to an exemption from registration
such as Rule 144, 144(k) or 701 under the Securities Act. Substantially all of
the Company's securities holders have executed lock-up agreements providing
that they will not directly or indirectly sell, contract to sell, grant any
option to purchase or otherwise transfer or dispose of any securities of the
Company until one year from the initial closing of this offering (the "Lock-up
Period") without the consent of the Representatives.     
   
  As a result of the foregoing lock-up agreements and securities law
restrictions, assuming no exercises of options or warrants after October 1,
1996, no shares of Common Stock will be eligible for resale without
restriction on the effective date of this offering pursuant to Rules 144 or
144(k). All of the issued and outstanding 1,911,111 shares upon the completion
of this offering (except for 309,144 shares which have been issued but are
subject to rights of repurchase) of Common Stock will be eligible for resale,
pursuant to Rule 144 or Rule 701 and subject to the volume limit restrictions
of Rule 144 or Rule 701, beginning one year from the closing of this offering.
An additional 414,134 shares of Common Stock issuable upon exercise of the
warrants issued in connection with the Placement and Representatives' Warrants
will become eligible for public sale as a result of registration rights
agreements with the Company. "Description of Capital Stock--Registration
Rights."     
   
  Shortly after this offering, the Company intends to file a registration
statement on Form S-8 covering approximately 587,134 shares of Common Stock
subject to certain outstanding options or reserved for issuance under the
Existing Plan (and the other Plans), thus permitting the resale of such shares
of Common Stock in the public market, except to the extent such shares are
subject to the Lock-up Period. Accordingly, shares registered under such
registration statement will, if and when issued, be available for sale in the
open market immediately following the expiration of the Lock-up Period.     
   
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned restricted shares for at least two years (including
the holding period of any prior owner except an affiliate) is entitled to
sell, within any three-month period, a number of shares that does not exceed
the greater of (i) one percent of the number of shares of Common Stock then
outstanding (which will equal approximately 2,761,111 shares immediately after
this offering) or (ii) the average weekly trading volume of the Common Stock
during the four calendar weeks preceding the filing of a Form 144 with respect
to such sale. Sales under Rule 144 are also subject to certain manner of sale
provisions and notice requirements and to the availability of current public
information about the Company. Under Rule 144(k), a person who is not deemed
to have been an affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares to be sold for at
least three years (including the holding period of any prior owner except an
affiliate), is entitled to sell such shares without complying with the manner
of sale, public information, volume limitation or notice provisions of Rule
144.     
 
  Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with the holding period requirements of Rule 144. Any employee,
officer or director of or consultant to the Company who purchased his or her
shares pursuant to a written compensatory plan or contract may be entitled to
rely on the resale provisions of Rule 701. Rule 701 further provides that non-
affiliates may sell such shares in reliance on Rule 144 without having to
comply with the holding period, public information, volume limitation or
notice provisions of Rule 144. Each holder of Rule 701 shares is required to
wait until 90 days after the date of this Prospectus before selling such
shares.

  The Underwriting Agreement provides that the obligations of the several
Underwriters are subject to the approval of certain legal matters by their
counsel and various other conditions. The maturing of the Underwriters'
obligations are such that they are committed to purchase all of the above
Securities if any are purchased.
   
  The Company has been advised by the Representatives that the Underwriters
propose to offer the Securities to the public at the public offering price set
forth on the cover page of this Prospectus and to certain dealers at such
price less a concession not in excess of $      per Share and $    per
Warrant. The Underwriters may allow, and such dealers may allow, a concession
not in excess of $      per Share and $    per Warrant to certain other
dealers. After this offering, the public offering price and concessions and
discounts may be changed by the Representatives. The Company has granted to
the Underwriters an option exercisable during the 45-day period commencing on
the date of this Prospectus to purchase from the Company, at the initial
public offering price less underwriting discounts and the non-accountable
expense allowance, up to an aggregate of      Units (representing 15% of the
Shares and Warrants to be sold in this offering) for the sole purpose of
covering over-allotments, if any. To the extent that the Underwriters exercise
the option, each Underwriter will have a firm commitment, subject to certain
conditions, to purchase the number of the additional Securities proportionate
to its initial commitment to purchase under the Underwriting Agreement.     
 
  The Representatives have informed the Company that they do not expect sales
to discretionary accounts by the Underwriters to exceed five percent of the
Securities offered hereby.
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act. The Company has
agreed to pay to the Representatives a non-accountable expense allowance equal
to 3% of the gross proceeds derived from the sale of the Securities
underwritten, of which $25,000 has been advanced.
 
  The Company has agreed to sell to the Representatives for $.0001 each the
Representatives' Warrants to purchase from the Company up to 10% of the Shares
and Warrants offered hereby. Each Representatives' Warrant will entitle the
holder to purchase one share of Common Stock at a price of $   per share,
which is 120% of the IPO Price Per Share and, upon payment of $  , which is
120% of the initial public offering price of the Warrants, to acquire one
Warrant at an exercise price equal to 150% of the IPO Price Per Share. The
Representatives' Warrants are, subject to certain conditions, exercisable at
any time until the fifth anniversary of the date of this Prospectus, and are
restricted from sale, transfer, assignment or hypothecation for a period of 12
months from the date of this Prospectus, except to officers of the
Representatives. The Representatives' Warrants
 
                                      54
<PAGE>
 
provide for adjustment in the exercise price of the Representatives' Warrants
in the event of certain mergers, acquisitions, stock dividends and capital
changes. The Representatives' Warrants grant to the holders thereof certain
rights with respect to the registration under the Securities Act of the
securities issuable upon exercise of the Representatives' Warrants.
 
  The offering price set forth on the cover page of this Prospectus should not
be considered an indication of the actual value of the Common Stock or the
Warrants. Such price is subject to change as a result of market conditions and
other factors and no assurance can be given that the Common Stock or Warrants
can be resold at the offering price.
   
  The Company, its officers and directors and other shareholders and option
and warrant holders holding approximately 2,579,591 shares of Common Stock
have agreed that for a period of 12 months following the closing of this
offering, they will not offer, sell, contract to sell, grant any option for
the sale or otherwise dispose of any securities of the Company (other than
intra-family transfers or transfers to trust for estate planning purposes),
without the Representatives' consent. These restrictions do not apply to (i)
the issuance of shares of Common Stock pursuant to the Underwriters' over-
allotment option, or (ii) the issuance of shares of Common Stock upon the
exercise of options and warrants outstanding prior to the sale of the shares
of Common Stock offered hereby, and (iii) bona fide pledges of shares of James
E. Alexander or Boris Rubizhevsky to banks or other financial institutions as
collateral for loans.     
 
  The Company has agreed that for a period of five years from the closing of
the sale of shares of Common Stock offered hereby, it will nominate for
election as a director a person designated by the Representatives, and during
such time as the Representatives have not exercised such right, the
Representatives shall have the right to designate an observer, who shall be
entitled to attend all meetings of the Board of Directors and to receive all
correspondence and communications sent by the Company to the members of the
Board. Larry J. Wells, a director of the Company, has been appointed as such
designee of the Representatives. The Company has agreed to reimburse designees
of the Representatives for their out-of-pocket expenses incurred in connection
with their attendance of meetings of the Board.
 
  Upon the exercise of any Warrants, which exercise was solicited by a
Representative, the Company has agreed to pay the Representative a commission
of 5% of the aggregate exercise price of such Warrants. Unless granted an
exemption by the Commission from Rule 10b-6 under the Exchange Act, the
Representative and any soliciting broker-dealers will be prohibited from
engaging in any market-making activities or solicited brokerage activities
with regard to the Company's securities for the periods prescribed by
exemption (xi) to Rule 10b-6 before the solicitation activity or the
termination (by waiver or otherwise) of any right that the Representative and
any soliciting broker-dealer may have to receive a fee for the exercise of the
Warrants following such solicitation. As a result, the Representative and any
soliciting broker-dealers may be unable to continue to provide a market for
the Common Stock or Warrants during certain periods while the Warrants are
exercisable. If the Representative has engaged in any of the activities
prohibited by Rule 10b-6 during the periods described above, the
Representative has undertaken to waive unconditionally its rights to receive a
commission on the exercise of such Warrants.

CELL GROWTH MEDIA: Substances used in a gel or solution that promote the
growth and multiplication of cells from simple or more complex organisms.
Organisms grown (fed) cell growth media labeled with enriched stable isotopes
result in new and more complex stable isotope labeled compounds.
 
CGMP (CURRENT GOOD MANUFACTURING PRACTICE): Part of quality assurance aimed at
ensuring that products are consistently manufactured to a quality appropriate
to their intended use; it incorporates manufacturing, engineering, quality
control and quality assurance activities.
 
CROSS SECTION: A fundamental property of the nucleus of an isotope, cross
section is a measure of the probability of interaction of the nucleus with
another nucleus, particle or photon.
 
DEPLETED STABLE ISOTOPE: An isotope of an element whose concentration or
"abundance" has been decreased with respect to that of the naturally occurring
element.
 
DEPLETED ZINC (DZ): Zinc oxide in which the stable isotope Zn-64 has been
depleted for application in nuclear power plants for corrosion control and the
mitigation of radiation fields.
 
DOPING: An impurity, such as boron, is added in small amounts to a pure
semiconductor to alter its conductive properties.
 
ENRICHED STABLE ISOTOPE: An isotope of an element whose concentration or
"abundance" has been increased with respect to that of the naturally occurring
element.
 
HIGH PURITY MATERIALS, CHEMICAL: Materials in which the relevant chemical
compound makes up more than >99.99% of the material.
 
H.PYLORI (Helicobacter pylori): A pathogenic bacterium found in the human
stomach, responsible for most peptic ulcers and some stomach cancers.
 
ISOTOPE: One of two or more naturally occurring species of atom having the
same atomic number, hence constituting the same element, but differing in mass
number. As atomic number is equivalent to the number of protons in the
nucleus, and mass number is the sum total of the protons plus the neutrons in
the nucleus, isotopes of the same element differ from one another only in the
number of neutrons in their nuclei. Isotopes may be radioactive or stable.
Isonics deals only with stable isotopes.
 
ISOTOPICALLY PURE MATERIALS: Materials in which a particular isotope has been
enriched to 99.5% abundance or greater in an element or in a compound.
 
ISOTOPICALLY ENGINEERED MATERIALS (IEM): Materials in which the natural
abundance of isotopes of constituent elements has been substantially altered
to enhance performance characteristics or provide unique properties.
 
MAGNETIC MOMENT: A fundamental property of the nucleus of an isotope, magnetic
moment is a vector quantity related to the intrinsic spin of a charged
particle. It is unique to each isotope and can be used to describe how a
spinning, charged particle will interact with an externally imposed magnetic
field (as in an NMR instrument or imaging scanner).
 
MASS SPECTROMETER: An apparatus that converts molecules and atoms into ions
and then separates the ions according to their mass-to-charge ratio. Mass
spectrometers are used to identify atoms and isotopes, and determine the
chemical composition of a sample.
 
NUCLEAR MAGNETIC RESONANCE (NMR): A phenomenon exhibited by a large number of
atomic nuclei, in which nuclei in a static magnetic field absorb energy from a
radio-frequency field at certain characteristic frequencies.
 
                                      57

The frequency at which resonance occurs is a function of the chemical form of
the nuclei of interest. This property is exploited in NMR instruments used to
determine the make-up and structure of chemicals. It is also employed in
medicine to produce 3-dimensional images of the distribution of protons (the
1H isotope of hydrogen) incorporated in the chemicals of the human body.
 
SPIN: A fundamental property of all elementary particles, spin is the
intrinsic angular momentum of a sub-atomic particle--present even if the
particle is not moving. If the particle is charged, the spin results in a
magnetic moment.
 
STABLE ISOTOPE LABELED COMPOUND (SILC): Also referred to as a "labeled
compound," a chemical which has been "tagged" by substitution of a common
isotope with a rare one (i.e., an enriched stable isotope).
   
X-RAY CRYSTALLOGRAPHY: The study of crystal lattices using diffraction
patterns of X-ray waves that reflect the atomic structure based on atomic size
and position in space.

The Board of Directors and Shareholders
Isonics Corporation
 
  We have audited the accompanying balance sheets of Isonics Corporation as of
April 30, 1995 and 1996, and the related statements of operations,
stockholders' equity (deficit) and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Isonics Corporation as of
April 30, 1995 and 1996, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

NOTE 1--ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION
 
  Isonics Corporation (the "Company") develops and markets products worldwide
based on enriched stable isotopes for applications in the energy, medical
research, diagnostic, pharmaceutical and semiconductor industries.
 
CASH EQUIVALENTS
 
  Cash equivalents consist of money market investments with an original
maturity of less than ninety days.
 
CONCENTRATION OF CREDIT RISK
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash equivalents and trade accounts
receivable. Cash equivalents are maintained with high quality institutions and
are regularly monitored by management. The Company extends credit to its
customers, most of whom are large, established companies. Credit risk is
mitigated by performing ongoing credit evaluations of its customers' financial
condition and generally does not require collateral.
 
INVENTORIES
 
  Inventories are stated at the lower of cost (first-in, first-out) or market.
 
PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over five to seven years. Leasehold improvements are
amortized over the shorter of their estimated useful lives or the lease term.
   
GOODWILL     
   
  Goodwill resulted from the acquisition of Isoserve, Inc., (see Note 10) and
is being amortized on a straight-line basis over six years. The Company
evaluates the realizability of goodwill annually to determine potential
impairment by comparing the undiscounted future cash flows of the related
assets. The Company modifies or adjusts goodwill if an impairment is
indicated. Based upon its most recent evaluation, the Company believes that no
material impairment of goodwill exists as of April 30, 1996 and July 31, 1996.
    
INCOME TAXES
 
  The Company accounts for income taxes using an asset and liability approach
for financial accounting and reporting purposes.
 
REVENUE RECOGNITION
   
  Revenue from product sales is recognized upon shipment. Product returns and
warranty costs have not been material in any period.

USE OF ESTIMATES IN THE FINANCIAL STATEMENTS
 
  In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements, as well as revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
  The fair value of cash and equivalents approximates carrying value due to
the short maturity of such instruments. The fair value of long-term debt
approximates carrying value based on terms available for similar instruments.
 
NET INCOME (LOSS) PER SHARE
 
  Net income (loss) per share is based on the weighted average number of
common and common equivalent shares outstanding during the period. Common
equivalent shares include convertible preferred stock (using the if-converted
method) and common stock options and warrants (using the treasury stock
method). Common equivalent shares are excluded from the computation in loss
periods as their effect is antidilutive, except that, pursuant to Securities
and Exchange Commission rules, all shares issuable from the exercise of
warrants issued and stock options granted by the Company at a price less than
the estimated initial public offering price during the twelve months preceding
the offering date have been included in the calculation (using the treasury
stock method) as if they had been outstanding for all periods.
 
UNAUDITED INTERIM FINANCIAL INFORMATION
 
  The unaudited interim financial information as of July 31, 1996 and for the
three months ended July 31, 1995 and 1996 has been prepared on the same basis
as the audited financial statements. In the opinion of management, such
unaudited information includes all adjustments (consisting only of normal
recurring accruals) necessary for a fair presentation of this interim
information. Operating results for the three months ended July 31, 1996 are
not necessarily indicative of the results that may be expected for the entire
year ending April 30, 1997.

  The valuation allowance for deferred tax assets as of April 30, 1995 and
1996 was $72,000 and none, respectively. The decrease in the valuation
allowance resulted from the realization of temporary differences and loss
carryforwards during the year and the reevaluation during 1995 that it was
more likely than not that the Company would generate taxable income sufficient
to realize the tax benefit associated with future deductible temporary
differences.

RECENTLY ISSUED ACCOUNTING STANDARD
 
  In October, 1995, the Financial Accounting Standards Board issued SFAS No.
123, Accounting for Stock-Based Compensation. The new standard establishes
financial accounting and reporting standards for stock-based compensation,
including stock-based employee compensation plans. The Statement defines a
fair value-based method of accounting for an employee stock option or similar
equity instrument. However, it also allows an entity to continue to measure
compensation cost for those plans using the intrinsic value-based method of
accounting prescribed by APB Opinion No, 25, Accounting for Stock Issued to
Employees. Entities electing to remain with the accounting in Opinion No. 25
must make pro forma disclosures of net income and earnings per share, as if
the fair value-based method of accounting defined in the Statement had been
applied. The Company will be required to adopt SFAS No. 123 for its year ended
April 30, 1997. Management of the Company has elected to make the pro forma
disclosure as allowed by SFAS No. 123.

NOTE 9--SIGNIFICANT CUSTOMERS AND SUPPLIERS
 
  In 1995, three customers accounted for approximately 59%, 26%, and 11% of

  The Company currently uses a single source processor in its manufacturing
process; a disruption of this relationship could have an adverse impact on the
operating results of the Company. The Company has not experienced a
disruption; however, the Company recognizes the risks and is actively pursuing
alternative sources.
 
NOTE 10--BUSINESS ACQUISITION
 
  In March 1995, the Company acquired certain assets and assumed certain

  The purchase price was allocated $211,000 to inventory and $472,000 to
goodwill. The Company is required to make royalty payments for depleted zinc
metal sold during the five years following the acquisition. Minimum annual
royalty payments of $100,000 are required regardless of sales volume until the
Company has paid $500,000 in aggregate. The maximum royalty payments under the
agreement are $1,000,000. The Company has accrued a liability for the present
value of the expected royalty payments. The royalty payments are secured by
the assets of the Company. The Company paid royalties of $196,000 and $45,000
for the year ended April 30, 1996 and the three month period ended July 31,
1996, respectively.

NOTE 11--SUBSEQUENT EVENTS (UNAUDITED)
   
  In August and September 1996, the Company issued $1,372,000 in
nonconvertible promissory notes, collateralized by the Company's assets.
Interest is payable monthly at 12% through May 1, 1997. If the notes are not
paid in full by May 1, 1997, the remaining principal and interest at 15% is
payable in equal monthly payments from June 1997 through May 1998. In the
event of an initial public offering of the Company's common stock, all
principal and accrued but unpaid interest is due five days after the closing
of such offering. In connection with the issuance of the promissory notes, the
Company issued warrants to the noteholders to purchase a total of 286,414
shares of common stock, exercisable for a period of five years commencing in
August 1996. Of the warrants issued, 143,207 are exercisable at $0.4217 per
share and 143,207 are exercisable at $3.3727 per share. If the Company
defaults in its payment obligations, then additional warrants totaling 377,458
are exercisable at $.01 per share. In conjunction with the financing, the
Company issued warrants to purchase 127,721 shares of common stock exercisable
for a period of five years, at $1.38 per share to a financial advisor. The
aggregate fair value of the warrants issued in connection with the financing
was $394,000 and will be amortized to operations as additional interest
expense over the term of the promissory notes. Of the total amount issued,
promissory notes in the amount of $570,000 were issued to officers, directors
and affiliates of the Company or such persons. Of the warrants issued, 127,552
were received by related parties.     
   
  In September 1996, two executive officers of the Company exercised stock
options to each acquire 108,853 shares of Common Stock at an exercise price of
$1.52 per share. In each case, the Company loaned the executive officer
$165,000, representing the exercise price of the option, and the officer
executed a promissory note reflecting the loan. Each executive officer pledged
the purchased shares as collateral for the loan pursuant to a pledge
agreement. Each loan bears interest at an annual rate equal to the minimum
applicable federal rate, and interest is payable annually; principal and
accrued but unpaid interest is due five years from the date of the note. Until
each note has been paid in full and upon any sale of such option shares by the
respective executive, a portion of the sales proceeds will be used to pay
amounts owed under the note. In addition, the Company has agreed to loan to
each such officer, pursuant to a five-year note with interest at the minimum
applicable federal rate, an amount equal to the federal and state tax
liability incurred by him as a result of exercising such option, and to pay
compensation to such officer equal to the amount of interest payable under his
loan and the amount of taxes payable as a result of such compensation.

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24 INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company's Articles of Incorporation include a provision that eliminates
to the fullest extent permitted by law the personal liability of its directors
to the Company and its shareholders for monetary damages for breach of the
directors fiduciary duties. This limitation has no effect on a director's
liability (i) for acts or omissions that involve intentional misconduct or a
knowing and culpable violation of law, (ii) for acts or omissions that a
director believes to be contrary to the best interests of the Company or its
shareholders or that involved the absence of good faith on the part of the
director, (iii) for any transaction from which the director derived an
improper personal benefit, (iv) for acts or omissions that show a reckless
disregard for the director's duty to the Company or its shareholders in
circumstances in which the director was aware, or should have been aware, in
the ordinary course of performing a director's duties, of a risk of serious
injury to the Company or its shareholders, (v) for acts or omissions that
constitute an unexcused pattern of inattention that amounts to an abdication
of the director's duty to the Company or its shareholders, (vi) under Section
310 of the California Corporations Code (the "California Code") concerning
contracts or transactions between the Company and a director or (vii) under
Section 316 of the California Code concerning directors liability for improper
dividends, loans and guarantees. The provision does not extend to acts or
omissions of a director in his capacity as an officer. Further, the provision
will not affect the availability of injunctions and other equitable remedies
available to the Company's shareholders for any violation of a director's
fiduciary duty to the Company or its shareholders.
 
  The Company's Articles of Incorporation further authorize the Company to
indemnify its agents (as defined in Section 317(a) of the Code which includes
directors and officers) through Bylaw provisions, agreements with agents,
votes of shareholders or disinterested directors or otherwise, to the fullest
extent permissible under California law. Pursuant to this provision, the
Company's Bylaws provide for indemnification of directors and officers. The
Bylaws also permit the Company to enter into indemnity agreements with
individual directors, officers, employees and other agents. The Company
intends to enter into such agreements with its directors and executive
officers effective upon the closing of this offering. These Agreements,
together with the Company's Bylaws and Articles, may require the Company,
among other things, to indemnify directors or officers against certain
liabilities that may arise by reason of their status or service as directors
(other than liabilities resulting from willful misconduct of a culpable
nature), to advance expenses to them as they are incurred, provided that they
undertake to repay the amount advanced if it is ultimately determined by a
court that they are not entitled to indemnification, and to obtain and
maintain directors and officers' insurance if available on reasonable terms.
 
  In addition to the rights to indemnification provided under California law,
in the Articles of Incorporation and in the Bylaws, the 1996 Stock Option Plan
provides indemnification to members of the Board of Directors, officers, or
employees of the Company to whom authority to act for the Board in connection
with the Existing Plan is delegated shall be indemnified against all
reasonable expenses, including attorneys' fees, actually and necessarily
incurred in defense of any proceeding to which he or she is made a party
because of any action allegedly taken or alleged failure to act in connection
with the Plan., and against amounts paid in settlement (if approved by
independent legal counsel), or in satisfaction of any judgment in such
proceeding, unless the director, officer, or employee, as the case may be, is
adjudged to have behaved in bad faith, in a grossly negligent manner, or with
intentional misconduct as to duties.
 
  The Company currently has directors and officers' liability insurance. At
present, there is no pending litigation or proceeding involving a director,
officer or employee of the Company pursuant to which indemnification is
sought, nor is the Company aware of any threatened litigation that may result
in claims for indemnification.

  Section 317 of the Code and the Company's Bylaws make provision for the
indemnification of officers, directors and other corporate agents in terms
sufficiently broad to indemnify such persons, under certain circumstances, for
liabilities (including reimbursement of expenses incurred) arising under the
Securities Act. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.
 
  Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

ITEM 28. UNDERTAKINGS.
 
  The Registrant hereby undertakes the following:
 
    (1) To file, during any period in which it offers or sells securities, a
  post-effective amendment to this registration statement to: (i) include any
  prospectus required by Section 10(a)(3) of the Securities Act; (ii) reflect
  in the prospectus any facts or events which, individually or together,
  represent a fundamental change in the information in the registration
  statement; and (iii) include any additional or changed material information
  of the plan of distribution.
 
    (2) 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.
 
    (3) For determining liability under the Securities Act, to treat the
  information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant under Rule 424(b)(1) or (4) or 497(h)
  under the Securities Act as part of this registration statement as of the
  time the Commission declared it effective.
 
    (4) For determining liability under the Securities Act, each post-
  effective amendment that contains a form of prospectus shall be deemed as a
  new registration statement for the securities offered therein, and that
  offering of the securities at that time shall be deemed to be the initial
  bona fide offering of those securities.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 24 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person 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 counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

(b) of Rule 430(A) of the Regulations), is hereinafter called the "Registration
Statement," and the form of prospectus in the form first filed with the
Commission pursuant to Rule 424(b) of the Regulations, is hereinafter called the
"Prospectus." For purposes hereof, "Regulations" mean the rules and regulations
adopted by the Commission under either the Act or the Securities Exchange Act of
1934, as amended (the "Exchange Act"), as applicable.

               (b) Neither the Commission nor any state regulatory authority has
issued any order preventing or suspending the use of any preliminary prospectus,
the Registration Statement or the Prospectus and no proceedings for a stop order
suspending the effectiveness of the Registration Statement have been instituted,
or, to the Company's knowledge, are threatened. Each of any preliminary
prospectus, the Registration Statement and the Prospectus at the time of filing
thereof conformed in all material respects with the requirements of the Act and
Regulations, and none of any preliminary prospectus, the Registration Statement
or the Prospectus at the time of filing thereof contained an untrue statement of
a material fact or omitted 

                                      -2-
<PAGE>
 
to state a material fact required to be stated therein and necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that this representation and warranty does not apply to
(i) statements made in reliance upon and in conformity with written information
furnished to the Company with respect to the Underwriters by or on behalf of the
Underwriters expressly for use in such preliminary prospectus, Registration
Statement or Prospectus, or (ii) statements made in the initial preliminary
prospectus which were revised in any subsequent preliminary prospectus or the
Registration Statement and Prospectus.

               (c) When the Registration Statement becomes effective and at all
times subsequent thereto up to the Closing Date (as defined in Section 2(c)
hereof) and each Option Closing Date (as defined in Section 2(b) hereof), if
any, and during such longer period as the Prospectus may be required to be
delivered in connection with sales by the Underwriters or a dealer, the
Registration Statement and the Prospectus, as amended or supplemented as
required, will contain all statements which are required to be stated therein in
accordance with the Act and the Regulations, and will conform in all material
respects to the requirements of the Act and the Regulations; neither the
Registration Statement nor the Prospectus, nor any amendment or supplement
thereto, will contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, provided, however, that this representation and warranty does
                --------  -------   
not apply to statements made or statements omitted in reliance upon and in
conformity with information furnished to the Company in writing by or on behalf
of any Underwriter expressly for use in the Registration Statement or the
Prospectus or any amendment thereof or supplement thereto.

               (d) The Company and each of its subsidiaries have been duly
organized and are validly existing as corporations in good standing under the
laws of the respective states of their incorporation. The Company does not own
or control, directly or indirectly, any corporation, partnership, trust, joint
venture or other business entity other than the subsidiaries listed in Exhibit
21 of the Registration Statement. Each of the Company and its subsidiaries is
duly qualified and licensed and in good standing as a foreign corporation in
each jurisdiction in which its ownership or leasing of any properties or the
character of its operations require such qualification or licensing, except
where the failure to be so qualified or licensed would not have a material and
adverse effect on the condition, financial or otherwise, or the business
affairs, operations, properties, or results of operations of the Company and its
subsidiaries, taken as a whole (the "Business"). Each of the Company and its
subsidiaries has all requisite power and authority (corporate and other), and
has obtained any and all necessary authorizations, approvals, orders, licenses,
certificates, franchises and permits of and from all governmental or regulatory
officials and bodies (including, without limitation, those having jurisdiction
over environmental or similar matters), to own or lease its properties and
conduct its business as described in the Prospectus, except where the failure to
have such authorizations, approvals, orders, licenses, certificates, franchises
or permits would not have a material and adverse effect on the Business; the
Company and each of its subsidiaries have been doing business in compliance in
all material respects with all such authorizations, approvals, orders, licenses,
certificates, franchises and permits and all federal, state, local and foreign
laws, rules and regulations; and neither the Company nor any of its subsidiaries
has received any notice of proceedings relating to the 

                                      -3-
<PAGE>
 
revocation or modification of any such authorization, approval, order, license,
certificate, franchise, or permit which, singly or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, would materially and
adversely affect the Business. The disclosures in the Registration Statement
concerning the effects of federal, state, local, and foreign laws, rules and
regulations on the Company's business as currently conducted and as contemplated
are correct in all material respects and do not omit to state a material fact
necessary to make the statements contained therein not misleading in light of
the circumstances in which they were made.

               (e) At the dates as of which such information is set forth in the
Prospectus, the Company had a duly authorized, issued and outstanding
capitalization as set forth in the Prospectus under the headings
"Capitalization" and "Description of Capital Stock" and will have the adjusted
capitalization set forth therein on the Closing Date and the Option Closing
Date, if any, based upon the assumptions set forth therein, and the Company is
not a party to or bound by any instrument, agreement or other arrangement
providing for it to issue any capital stock, rights, warrants, options or other
securities, except for this Agreement and as described in the Prospectus. The
Securities and all other securities issued or issuable by the Company conform
or, when issued and paid for, will conform, in all material respects to all
statements with respect thereto contained in the Registration Statement and the
Prospectus. All issued and outstanding shares of capital stock of each
subsidiary of the Company have been duly authorized and validly issued and are
fully paid and nonassessable. Except as disclosed in or contemplated by the
Prospectus and the financial statements of the Company and the related notes
thereto included in the Prospectus, neither the Company nor any subsidiary has
outstanding any options to purchase, or any preemptive rights or other rights to
subscribe for or to purchase, any securities or obligations convertible into, or
any contracts or commitments to issue or sell, shares of its capital stock or
any such options, rights, convertible securities or obligations. The description
of the Company's stock option, stock bonus and other stock plans or arrangements
and the options or other rights granted and exercised thereunder as set forth in
the Prospectus conforms in all material respects with the requirements of the
Act. All issued and outstanding securities of the Company have been duly
authorized and validly issued and are fully paid and nonassessable, and the
holders thereof have no rights of rescission with respect thereto and are not
subject to personal liability by reason of being such holders; and none of such
securities were issued in violation of the preemptive rights of any holders of
any security of the Company or similar contractual rights granted by the
Company.

               (f) The Securities are not and will not be subject to any
preemptive or other similar rights of any stockholder, have been duly authorized
and, when issued, paid for and delivered in accordance with the terms hereof,
will be validly issued, fully paid and nonassessable and will conform in all
material respects to the description thereof contained in the Prospectus; the
holders thereof will not be subject to any liability solely as such holders; all
corporate action required to be taken for the authorization, issue and sale of
the Securities has been duly and validly taken; and the certificates
representing the Securities will be in due and proper form. Upon the issuance
and delivery pursuant to the terms hereof of the Securities to be sold by the
Company hereunder, the Underwriters or the Representatives, as the case may be,
will acquire good and marketable title to such Securities free and clear of any
lien, charge, claim, encumbrance, pledge, security interest, defect, or other
restriction or equity of any kind 

                                      -4-
<PAGE>
 
whatsoever. No stockholder of the Company has any right which has not been
waived in writing to require the Company to register the sale of any shares
owned by such stockholder under the Act in the public offering contemplated by
this Agreement. No further approval or authority of the stockholders or the
Board of Directors of the Company will be required for the issuance and sale of
the Shares, the Option Shares and the Representatives' Warrants to be sold by
the Company as contemplated herein.

               (g) The financial statements of the Company, together with the
related notes and schedules thereto, included in the Registration Statement,
each Preliminary Prospectus and the Prospectus fairly present the financial
position, changes in stockholders' equity and the results of operations of the
Company and its consolidated subsidiaries (of which there are none) at the
respective dates and for the respective periods to which they apply and such
financial statements have been prepared in conformity with generally accepted
accounting principles and the Regulations, consistently applied throughout the
periods involved. Except as disclosed in the Prospectus, there has been no
material adverse change or development involving a material prospective change
in the Business, whether or not arising in the ordinary course of business since
the date of the financial statements included in the Registration Statement and
the Prospectus and the outstanding debt, the property, both tangible and
intangible, and the business of the Company and its subsidiaries taken as a
whole conform in all material respects to the descriptions thereof contained in
the Registration Statement and the Prospectus. Financial information set forth
in the Prospectus under the headings "Prospectus Summary - Selected Financial
Data," "Capitalization," and "Management's Discussion and Analysis of Financial
Condition and Results of Operations," fairly present, on the basis stated in the
Prospectus, the information set forth therein and have been derived from or
compiled on a basis consistent with that of the audited and unaudited financial
statements included in the Prospectus.

               (h) The Company (i) has paid all federal, state, local,
franchise, and foreign taxes for which it is liable (except for immaterial non-
payments, if any), including, but not limited to, withholding taxes and amounts
payable under Chapters 21 through 24 of the Internal Revenue Code of 1986, as
amended (the "Code"), and has furnished all information returns it is required
to furnish pursuant to the Code, (ii) has established adequate reserves for such
taxes which are not due and payable, and (iii) does not have any material tax
deficiency or claims outstanding, proposed or assessed against it.

               (i) No transfer tax, stamp duty or other similar tax is payable
by or on behalf of the Underwriters in connection with (i) the issuance by the
Company of the Securities, (ii) the purchase by the Underwriters of the Firm
Securities and the Option Securities from the Company and the purchase by the
Representatives of the Representatives' Warrants from the Company, (iii) the
consummation by the Company of any of its obligations under this Agreement, or
(iv) resales of the Firm Securities and the Option Securities in connection with
the distribution contemplated hereby.

               (j) There is no action, suit, proceeding, inquiry, arbitration,
mediation, investigation, litigation or governmental proceeding (including,
without limitation, any involving environmental or similar matters), domestic or
foreign, pending or threatened against (or 

                                      -5-
<PAGE>
 
circumstances that may give rise to the same), or involving the properties or
businesses of, the Company which (i) questions the validity of the capital stock
of the Company, this Agreement or the Representatives' Warrant Agreement, or of
any action taken or to be taken by the Company pursuant to or in connection with
this Agreement or the Representatives' Warrant Agreement, (ii) is required to be
disclosed in the Registration Statement which is not so disclosed (and such
proceedings as are summarized in the Registration Statement are accurately
summarized in all material respects), or (iii) could reasonably be expected to
materially and adversely affect the Business.

               (k) The Company has the corporate power and authority to
authorize, issue, deliver, and sell the Securities and to enter into this
Agreement, the Warrant Agreement, and the Representatives' Warrant Agreement,
and to consummate the transactions provided for in such agreements; and this
Agreement, the Warrant Agreement and the Representatives' Warrant Agreement have
each been duly and properly authorized, executed, and delivered by the Company.
Each of this Agreement, the Warrant Agreement and the Representatives' Warrant
Agreement constitutes a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its respective terms (except
as the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
relating to or affecting enforcement of creditors' rights and the application of
equitable principles in any action, legal or equitable, and except as rights to
indemnity or contribution may be limited by applicable law), and none of the
issue and sale of the Securities, execution, delivery or performance by the
Company of this Agreement, the Warrant Agreement, and the Representatives'
Warrant Agreement, the consummation by the Company of the transactions
contemplated herein and therein, or the conduct of the Company's businesses as
described in the Registration Statement, the Prospectus, and any amendments or
supplements thereto, conflicts with or will conflict with or results or will
result in any breach or violation of any of the terms or provisions of, or
constitutes or will constitute a default under, or result in the creation or
imposition of any lien, charge, claim, encumbrance, pledge, security interest,
defect or other restriction or equity of any kind whatsoever upon, any property
or assets (tangible or intangible) of the Company pursuant to the terms of (i)
the articles of incorporation or by-laws of the Company, as amended and
restated, (ii) any license, contract, indenture, mortgage, deed of trust, voting
trust agreement, stockholders agreement, note, loan or credit agreement or any
other agreement or instrument to which the Company is a party or by which it is
or may be bound or to which its properties or assets (tangible or intangible) is
or may be subject, or (iii) any statute, judgment, decree, order, rule or
regulation applicable to the Company of any arbitrator, court, regulatory body
or administrative agency or other governmental agency or body (including,
without limitation, those having jurisdiction over environmental or similar
matters), domestic or foreign, having jurisdiction over the Company or any of
its activities or properties, in each of the above instances which could
reasonably be expected to materially and adversely affect the Business.

               (l) No consent, approval, authorization or order of, and no
filing with, any court, regulatory body, government agency or other body,
domestic or foreign, is required for the issuance and sale of the Securities
pursuant hereto, and the Prospectus and the Registration Statement, the
performance of this Agreement, the Warrant Agreement, and the Representatives'

                                      -6-
<PAGE>
 
Warrant Agreement, and the transactions contemplated hereby and thereby,
including without limitation, any waiver of any preemptive, first refusal or
other rights that any entity or person may have for the issue and/or sale of any
of the Securities, except such as have been or may be obtained under the Act or
may be required under state securities or Blue Sky laws in connection with the
Underwriters' purchase and distribution of the Firm Securities, the Option
Securities, and the Representatives' Warrants to be sold by the Company
hereunder.

               (m) All executed agreements, contracts or other documents or
copies of executed agreements, contracts or other documents filed as exhibits to
the Registration Statement to which the Company is a party or by which it may be
bound or to which its assets, properties or businesses may be subject have been
duly and validly authorized, executed and delivered by the Company and
constitute the legal, valid and binding agreements of the Company enforceable
against the Company in accordance with their respective terms (except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application relating to or
affecting enforcement of creditors' rights and the application of equitable
principles in any action, legal or equitable, and except as rights to indemnity
or contribution may be limited by applicable law). The descriptions in the
Registration Statement of such agreements, contracts and other documents are
accurate in all material respects and fairly present the information required to
be shown with respect thereto by Form SB-2, and there are no contracts or other
documents which are required by the Act to be described in the Registration
Statement or filed as exhibits to the Registration Statement which are not
described or filed as required, and the exhibits which have been filed are
complete and correct copies of the documents of which they purport to be copies.

               (n) Since the respective dates as of which information is given
in the Registration Statement and Prospectus, and except as described in or
specifically contemplated by the Prospectus (i) the Company has not incurred any
material liabilities or obligations, indirect, direct or contingent, or entered
into any material verbal or written agreement or other transaction which is not

Company has not sustained any material loss or interference with its business or

Company is not in default in the payment of principal or interest on any
outstanding debt obligations; (iv) there has not been any change in the capital
stock (other than upon the sale of the Firm Securities, the Option Securities
and the Representatives' Warrants hereunder and upon the exercise of options and
warrants described in the Registration Statement) of, or indebtedness material
to, the Company (other than in the ordinary course of business); (v) the Company
has not issued any securities or incurred any liability or obligation, primary
or contingent, for borrowed money; and (vi) there has not been any material
adverse change in the Business.

               (o) Except as disclosed in or specifically contemplated by the
Prospectus, and subject to the risks and uncertainties described in the
Prospectus under the headings entitled "Risk Factors ___ Protection of
Intellectual Property" and "Business ___ Patents and Proprietary Rights," (i)
the Company has sufficient trade names, licenses, approvals and governmental

                                      -7-
<PAGE>
 
authorizations to conduct its business as now conducted; (ii) the expiration of

other infringement which could reasonably be expected to have a material adverse
effect on the Business.

               (p) No default exists in the due performance and observance of
any term, covenant or condition of any material license, contract, indenture,
mortgage, installment sale agreement, lease, deed of trust, voting trust
agreement, stockholders agreement, note, loan or credit agreement, or any other
material agreement or instrument evidencing an obligation for borrowed money, or
any other material agreement or instrument to which the Company is a party or by
which the Company may be bound or to which the property or assets (tangible or
intangible) of the Company are subject or affected, except for such defaults, if
any, which individually and in the aggregate would not have a material adverse
effect on the Business.

               (q) To the Company's knowledge, there are no investigations
involving the Company by any governmental agency. There is no unfair labor
practice charge or complaint against the Company pending before the National

"multiemployer plan" as such terms are defined in Sections 3(2), 3(1) and 3(37),
respectively, of the Employee Retirement Income Security Act of 1974, as amended

any trust created thereunder) has engaged in a "prohibited transaction" within
the meaning of Section 406 of ERISA or Section 4975 of the Code, which could
subject the Company to any tax penalty on prohibited transactions and which has
not adequately been corrected. Each ERISA Plan is in compliance with all
material reporting, disclosure and other requirements of the Code and ERISA as
they relate to any such ERISA Plan. Determination letters have been received
from the Internal Revenue Service with respect to each ERISA Plan which is
intended to comply with Code Section 401(a), stating that such ERISA Plan and
the attendant trust are qualified thereunder. The Company has never completely
or partially withdrawn from a "multiemployer plan."

               (s) Neither the Company nor any of its employees, directors,
stockholders, or affiliates (within the meaning of the Regulations) of any of
the foregoing has taken or will 

                                      -8-
<PAGE>
 
take, directly or indirectly, any action designed to or which has constituted or
which might be expected to cause or result in unlawful stabilization or
manipulation of the price of any security of the Company to facilitate the sale
or resale of the Securities.

               (t) Except for a security interest granted to Isoserve, Inc.
pursuant to a Security Agreement between Isoserve and the Company, the Company
has good and marketable title to, or valid and enforceable leasehold estates in,
all items of real and personal property stated in the Prospectus to be owned or
leased by it, free and clear of all liens, charges, claims, encumbrances,
pledges, security interests, or other restrictions or equities of any kind
whatsoever, other than those referred to in the Prospectus and liens for taxes
not yet due and payable or for such as do not materially affect the value of the
Company's real and personal property, taken as a whole.

               (u) To the Company's knowledge, Grant Thornton LLP ("Grant
Thornton"), whose report is filed with the Commission as a part of the
Registration Statement, is an independent certified public accountant as
required by the Act and the Regulations.

               (v) The Company has caused to be duly executed legally binding
and enforceable agreements pursuant to which all persons or entities, other than
as set forth in the Prospectus, that directly or beneficially own Common Stock,
as of the effective date of the Registration Statement, have agreed not to,
directly or indirectly, offer, offer to sell, sell, grant any option for the
sale of, transfer, assign, pledge, hypothecate or otherwise encumber or dispose
of any shares of Common Stock or securities convertible into Common Stock,
exercisable or exchangeable for or evidencing any right to purchase or subscribe
for any shares of Common Stock (either pursuant to Rule 144 of the Regulations
or otherwise) or dispose of any interest therein for a period from the date of
the Prospectus until and including the day of like number in the twelfth
consecutive month next following the date that the Registration Statement
becomes effective, without the prior written consent of Pryor, McClendon (the
"Lock-up Agreements"). The Company will cause the Transfer Agent (as defined
herein) to place "stop transfer" orders on the Company's stock ledgers in order
to effect the Lock-up Agreements.

               (w) Except as disclosed to the Representatives, there are no
claims, payments, arrangements or understandings, whether oral or written, for
services in the nature of a finder's or origination fee with respect to the sale
of the Securities hereunder or any other arrangements, agreements,
understandings, payments or issuance with respect to the Company or any of its
officers, directors, stockholders, employees or affiliates that may affect the
Underwriters' compensation as determined by the Commission and the National
Association of Securities Dealers, Inc. (the "NASD").

               (x) The Securities have been approved for quotation on the Nasdaq
SmallCap Market.

               (y) Neither the Company nor any of its officers, employees,
agents or any other person acting on behalf of the Company has, directly or
indirectly, given or agreed to give any money, gift or similar benefit (other
than legal price concessions to customers in the ordinary

                                      -9-
<PAGE>
 
course of business) to any customer, supplier, employee or agent of a customer
or supplier, or official or employee of any governmental agency (domestic or
foreign) or instrumentality of any government (domestic or foreign) or any
political party or candidate for office (domestic or foreign) or other person
who was, is, or may be in a position to help or hinder the business of the
Company (or assist the Company in connection with any actual or proposed
transaction) which might subject the Company or any other such person to any
damage or penalty in any civil, criminal or governmental litigation or
proceeding (domestic or foreign). The Company's internal accounting controls are
sufficient to cause the Company to comply with the Foreign Corrupt Practices Act
of 1977, as amended.

               (z) Except as set forth in the Prospectus, no officer, director
or stockholder of the Company, or any "affiliate" or "associate" (as these terms
are defined in Rule 405 of the Regulations) of any of the foregoing persons or
entities has or has had, either directly or indirectly, (i) an interest in any
person or entity which (A) furnishes or sells services or products which are
furnished or sold or are proposed to be furnished or sold by the Company, or (B)
purchases from or sells or furnishes to the Company any goods or services, or
(ii) a beneficial interest in any contract or agreement to which the Company is
a party or by which it may be bound or affected. Except as set forth in the
Prospectus, there are no existing agreements, arrangements, understandings or
transactions, or proposed agreements, arrangements, understandings or
transactions, between or among the Company, and any officer, director, principal
shareholder (as such term is used in the Prospectus) of the Company, or any
affiliate or associate of any of the foregoing persons or entities which are
required to be disclosed in the Prospectus.

               (aa) The Company is not, and does not intend to conduct its
business in a manner in which it would become an "investment company" within the
meaning of the Investment Company Act of 1940, as amended.

               (ab) Any certificate signed by any officer of the Company and
delivered to the Underwriters or to the Underwriters' Counsel (as defined in
Section 4(d) herein) shall be deemed a representation and warranty by the
Company to the Underwriters as to the matters covered thereby.

               (ac) The minute books of the Company have been made available to
the Underwriters and contain a complete summary of all meetings and actions of
the directors and stockholders of the Company since the time of its
incorporation, and reflect all transactions referred to in such minutes
accurately in all material respects.

               (ad) The Company has not distributed and will not distribute any
offering material in connection with the offering and sale of the Shares in this
offering other than the Prospectus, the Registration Statement and the other
materials permitted by the Act. Except as described in the Prospectus, no
holders of any securities of the Company or of any options, warrants or other
convertible or exchangeable securities of the Company have the right to include
any securities issued by the Company as part of the Registration Statement or to
require the

                                      -10-
<PAGE>
 
Company to file a registration statement under the Act and no person or entity
holds any anti-dilution rights with respect to any securities of the Company.

               (ae) Except for the absence of policies which are disclosed in
the Prospectus, the Company maintains insurance by insurers of recognized
financial responsibility of the types and in the amounts as the Company believes
are prudent and adequate for the business in which it is engaged, including, but
not limited to, insurance covering real and personal property owned or leased by
the Company against theft, damage, destruction, acts of vandalism and all other
risks customarily insured against, all of which insurance is in full force and
effect. The Company has delivered to the Underwriter's Counsel satisfactory
summaries of these insurance policies. The Company has no reason to believe that
it will not be able to renew existing insurance coverage with respect to the
Company as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business, in either case,
at a cost that would not have a material adverse effect on the financial
condition, operations, business, assets or properties of the Company. The
Company has not failed to file any material claims, has no material disputes
with its insurance company regarding any claims submitted under its insurance
policies, and has complied in material respects with all material provisions
contained in its insurance policies where the failure to could reasonably be
expected to have a material adverse effect on the Business.

share of Common Stock and an additional ___________________ Warrants at a price
of $__________ per Warrant (which shares and Warrants may only be purchased
together on the basis of one share and one Warrant). The option granted hereby
will expire 45 days after (i) the date the Registration Statement becomes
effective, if the Company has elected not to rely on Rule 430A under the
Regulations, or (ii) the date of this Agreement if the Company has elected to
rely upon Rule 430A under the Regulations, and may be exercised in whole or in
part from time to time (but not on more than two (2) occasions) only for the
purpose of covering over-allotments which may be made in connection with the
offering and distribution of the Firm Securities upon notice by the
Representatives to the Company setting forth the number of Option Securities as
to which the 

                                      -11-
<PAGE>
 
several Underwriters are then exercising the option and the time and date of
payment and delivery for any such Option Securities. Any such time and date of
delivery (an "Option Closing Date") shall be determined by the Representatives,
but shall not be later than three full business days after the exercise of said
option, nor in any event prior to the Closing Date, as hereinafter defined,
unless otherwise agreed upon by the Representatives and the Company. Nothing
herein contained shall obligate the Underwriters to exercise the over-allotment
option described above. No Option Securities shall be delivered unless the Firm
Securities shall be simultaneously delivered or shall theretofore have been
delivered as herein provided.

               (c)  Payment of the purchase price for, and delivery of
certificates for, the Firm Securities shall be made at the offices of Pryor,
McClendon, Counts & Co., Inc., 3 Penn Plaza, 1515 Market Street, Suite 819,
Philadelphia, Pennsylvania, or at such other place as shall be agreed upon by
the Representatives and the Company. Such delivery and payment shall be made at
9:00 a.m. (New York time) on ______________, 1996, or at such other time and
date as shall be agreed upon by the Representatives and the Company, but no more
than four (4) business days after the date hereof (such time and date of payment
and delivery being herein called the "Closing Date"). In addition, in the event
that any or all of the Option Securities are purchased by the Underwriters,
payment of the purchase price for, and delivery of certificates for, such Option
Securities shall be made at the above mentioned office of Pryor, McClendon or at
such other place as shall be agreed upon by the Representatives and the Company
on each Option Closing Date as specified in the notice from the Representatives
to the Company. Delivery of the certificates for the Firm Securities and the
Option Securities, if any, shall be made to the Underwriters against payment by
the Underwriters of the purchase price for the Firm Securities and the Option
Securities, if any, to the order of the Company. In the event Option Securities
are to be purchased by the Underwriters, each of the Underwriters, acting
severally and not jointly, shall purchase that proportion of the total number of
Option Securities then being purchased which the number of Firm Securities set
forth in Schedule A hereto opposite the name of such Underwriter bears to the
total number of Firm Securities, subject in each case to such adjustments as the
Representatives in their discretion shall make to eliminate any sales or
purchases of fractional shares. Certificates for the Firm Securities and the
Option Securities, if any, shall be in definitive, fully registered form, shall
bear no restrictive legends and shall be in such denominations and registered in
such names as the Underwriters may request in writing at least three (3)
business days prior to Closing Date or the relevant Option Closing Date, as the
case may be. The certificates for the Firm Securities and the Option Securities,
if any, shall be made available to the Representatives at such office or such
other place as the Representatives may designate for inspection, checking and
packaging no later than 9:30 a.m. on the last business day prior to Closing Date
or the relevant Option Closing Date, as the case may be.

               (d)  On the Closing Date, the Company shall issue and sell the
Representatives' Warrants to the Representatives at a purchase price of $0.0001
per warrant, which warrants shall entitle the holders thereof to purchase an
aggregate of _________________ shares of Common Stock and _________________
Warrants.  The Representatives' Warrants shall expire five (5) years after the
effective date of the Registration Statement and shall be exercisable for a
period of four (4) years commencing on the first anniversary of the effective
date of the Registration Statement at a price equaling one hundred twenty
percent (120%) of the initial public offering 

                                      -12-
<PAGE>
 
price of the Shares. The Representatives' Warrant Agreement and form of Warrant
Certificate shall be substantially in the form filed as Exhibit 4.2 to the
Registration Statement. Payment for the Representatives' Warrants shall be made
on the Closing Date.

          3.  Public Offering of the Shares and the Warrants.  As soon after the
              ----------------------------------------------                    
Registration Statement becomes effective as the Representatives deem advisable,
the Underwriters shall make a public offering of the Shares and the Warrants
(other than to residents of or in any jurisdiction in which qualification of the
Shares and the Warrants is required and has not become effective) at the price
and upon the other terms set forth in the Prospectus.  The Representatives may
from time to time increase or decrease the public offering price to such extent
as the Representatives, in their sole discretion, deem advisable and as
permitted by the Act and Regulations.  The Underwriters may enter into one or
more agreements as the Underwriters, in each of their sole discretion, deem
advisable with one or more broker-dealers who shall act as dealers in connection
with such public offering.

          4.  Covenants of the Company.  The Company covenants and agrees with
              ------------------------                                        
each of the Underwriters as follows:

               (a)  The Company shall use its best efforts to cause the
Registration Statement and any amendments thereto to become effective as
promptly as practicable and will not at any time, whether before or after the
effective date of the Registration Statement, file any amendment to the
Registration Statement or supplement to the Prospectus or file any document
under the Act or Exchange Act before termination of the offering of the Shares
and the Warrants by the Underwriters of which the Representatives shall not
previously have been advised and furnished with a copy, or to which the
Representatives shall have objected or which is not in compliance with the Act,
the Exchange Act or the Regulations.

               (b)  As soon as the Company is advised or obtains knowledge
thereof, the Company will advise the Representatives and confirm the notice in
writing, (i) when the Registration Statement, as amended, becomes effective, if
the provisions of Rule 430A promulgated under the Act will be relied upon, when
the Prospectus has been filed in accordance with said Rule 430A and when any
post-effective amendment to the Registration Statement becomes effective, (ii)
of the issuance by the Commission of any stop order or of the initiation, or the
threatening, of any proceeding, suspending the effectiveness of the Registration
Statement or any order preventing or suspending the use of any preliminary
prospectus or the Prospectus, or any amendment or supplement thereto, or the
institution of proceedings for that purpose, (iii) of the issuance by the
Commission or by any state securities commission of any proceedings for the
suspension of the qualification of any of the Securities for offering or sale in
any jurisdiction or of the initiation, or the threatening, of any proceeding for
that purpose, (iv) of the receipt of any comments from the Commission; and (v)
of any request by the Commission for any amendment to the Registration Statement
or any amendment or supplement to the Prospectus or for additional information.
If the Commission or any state securities commission shall enter a stop order or
suspend such qualification at any time, the Company will use its best efforts to
obtain promptly the lifting of such order.

                                      -13-
<PAGE>
 
               (c)  The Company shall file the Prospectus (in form and substance
satisfactory to the Representatives) in accordance with the requirements of the
Act.

               (d)  The Company will give the Representatives notice of its
intention to file or prepare any amendment to the Registration Statement
(including any post-effective amendment) or any amendment or supplement to the
Prospectus (including any revised prospectus which the Company proposes for use
by the Underwriters in connection with the offering of the Securities which
differs from the corresponding prospectus on file at the Commission at the time
the Registration Statement becomes effective, whether or not such revised
prospectus is required to be filed pursuant to Rule 424(b) of the Regulations),
and will furnish the Representatives with copies of any such amendment or
supplement a reasonable amount of time prior to such proposed filing or use, as
the case may be, and will not file any such amendment or supplement to which the
Representatives or Camhy Karlinsky & Stein LLP ("Underwriters' Counsel") shall
reasonably object.

               (e)  The Company shall endeavor in good faith, in cooperation
with the Representatives, at or prior to the time the Registration Statement
becomes effective, to qualify the Securities for offering and sale under the
securities laws of such jurisdictions as the Representatives may reasonably
designate to permit the sales and dealings therein for as long as may be
necessary to complete the distribution, and shall make such applications, file
such documents and furnish such information as may be required for such purpose;
provided, however, the Company shall not be required to qualify as a foreign 
- --------  -------
corporation or become subject to service of process in any such jurisdiction. In
each jurisdiction where such qualification shall be effected, the Company will,
unless the Representatives agree that such action is not at the time necessary
or advisable, use all reasonable efforts to file and make such statements or
reports at such times as are required by the laws of such jurisdiction to
continue such qualification.

               (f)  During the time when a prospectus is required to be
delivered under the Act, the Company shall use all reasonable efforts to comply
with all requirements imposed upon it by the Act, as now and hereafter amended,
and by the Regulations, as from time to time in force, so far as necessary to
permit the continuance of sales of or dealings in the Securities in accordance
with the provisions hereof and the Prospectus, or any amendments or supplements
thereto. If at any time when a prospectus relating to the Securities is required
to be delivered under the Act, any event shall have occurred as a result of
which, in the opinion of counsel for the Company or Underwriters' Counsel, the
Prospectus, as then amended or supplemented, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, or if it is necessary at any time to
amend or supplement the Prospectus to comply with the Act, the Company will
notify the Representatives promptly and prepare and file with the Commission an
appropriate amendment or supplement in accordance with Section 10 of the Act,
each such amendment or supplement to be satisfactory to Underwriters' Counsel,
and the Company will furnish to the Underwriters copies of such amendment or
supplement as soon as available and in such quantities as the Underwriters may
request.

               (g)  As soon as practicable, but in any event not later than 45
days after the end of the 12-month period beginning on the day after the end of
the fiscal quarter of the Company during which the effective date of the
Registration Statement occurs (90 days in the event that the end of such fiscal
quarter is the end of the Company's fiscal year), the Company shall make
generally available to its security holders, in the manner specified in Rule
158(b) of the Regulations, and to the Representatives, an earnings statement
which will be in the detail required by, and will otherwise comply with, the
provisions of Section 11(a) of the Act and Rule 158(a) of the Regulations, which

          its stockholders, a consolidated statement of income of the Company
          and its consolidated subsidiaries for each quarter in the form
          furnished to the Company's stockholders;

                  (ii)  concurrently with furnishing such annual reports to its
          stockholders, a consolidated balance sheet of the Company and its
          consolidated subsidiaries as at the end of the preceding fiscal year,

          subsidiaries for such fiscal year, accompanied by a copy of the report
          thereon of independent certified public accountants;

                  (iii) as soon as they are available, copies of all other
          reports (financial or other) mailed to stockholders;

                  (iv)  as soon as they are available, copies of all reports and
          financial statements furnished to or filed with the Commission, Nasdaq
          or any securities exchange;

                  (v)   every press release and every material news item or
          article of interest to the financial community in respect of the
          Company or its affairs which was released or prepared by or on behalf
          of the Company; and

                  (vi)  any additional information of a public nature concerning
          the Company and its Businesses which the Representatives may
          reasonably request.

                                      -15-

          During such five-year period, the foregoing financial statements will
be accompanied by similar financial statements for any significant subsidiary
which is not consolidated.

               (i)  The Company will maintain a transfer agent (the "Transfer
Agent") and, if necessary under the jurisdiction of incorporation of the
Company, a registrar (which may be the same entity as the transfer agent) for
the Securities and the Representatives' Warrants.

               (j)  The Company will furnish to the Representatives, without
charge, at such place as the Representatives may designate, copies of each
preliminary prospectus, the Registration Statement, the Prospectus and any pre-
effective or post-effective amendments thereto (two of which copies will be
signed and will include all financial statements and exhibits), in each case as
soon as available and in such quantities as the Representatives may reasonably
request.

               (k)  On or before the effective date of the Registration
Statement, the Company shall provide the Representatives with true copies of
duly executed Lock-up Agreements. On or before the Closing Date, the Company
shall deliver instructions to the Transfer Agent authorizing it to place
appropriate stop transfer orders on the Company's ledgers.

               (l)  The Company shall use its best efforts to cause its
officers, directors, stockholders or affiliates (within the meaning of the
Regulations) not to take, directly or indirectly, any action designed to, or
which might in the future reasonably be expected to cause or result in, unlawful
stabilization or manipulation of the price of any securities of the Company.

               (m)  The Company shall apply the net proceeds from the sale of
the Securities substantially in the manner, and subject to the conditions, set
forth under "Use of Proceeds" in the Prospectus.

               (n)  The Company shall timely file all such reports, forms or
other documents as may be required (including, but not limited to, a Form SR as
may be required pursuant to Rule 463 under the Act) from time to time, under the
Act, the Exchange Act, and the Regulations, and all such reports, forms and
documents filed will comply as to form and substance with the applicable
requirements under the Act, the Exchange Act, and the Regulations.

               (o)  The Company shall use its best efforts to cause the
Securities to be quoted on the Nasdaq SmallCap Market, and for a period of two
(2) years from the date hereof shall use its best efforts to maintain the

               (p)  For a period of two (2) years from the Closing Date, the
Company shall furnish to the Representatives, at the Company's sole expense,
monthly transfer sheets relating to the Common Stock and Warrants.

<PAGE>
 
               (q)  For a period of five (5) years after the effective date of
the Registration Statement the Company shall, at the Company's sole expense,
take all reasonable and appropriate actions to qualify the Common Stock and
Warrants in all jurisdictions of the United States which do not require the
Company to qualify as a foreign corporation or to file a general consent to
service of process in order to permit secondary sales of such securities
pursuant to the Blue Sky laws of those jurisdictions.

               (r)  The Company (i) prior to the effective date of the
Registration Statement has filed a Form 8-A with the Commission providing for
the registration of the Common Stock and Warrants under the Exchange Act and
(ii) as soon as practicable will use its best efforts to take all necessary and
appropriate actions to be included in Standard and Poor's Corporation
Descriptions or Moody's OTC Manual and to continue such inclusion for a period
of not less than five (5) years (or, if sooner, the date on which the Common
Stock and Warrants are listed on the New York Stock Exchange, American Stock
Exchange, or Nasdaq National Market).

               (s)  The Company agrees that for a period of twelve (12) months
following the effective date of the Registration Statement it will not, without
the prior written consent of Pryor, McClendon, offer, issue, sell, contract to
sell, grant any option for the sale of or otherwise dispose of any Common Stock
or securities convertible into Common Stock, except for the issuance of shares
of Common Stock registered under the Act pursuant to the Registration Statement,
or except pursuant to incentive or benefit plans approved by the Board of
Directors of the Company, pursuant to options or warrants outstanding on the
Closing Date, or in connection with acquisitions of companies, products or
technologies.

               (t)  Until the completion of the distribution of the Securities
in connection with the initial public offering of the Securities, the Company
shall not without the prior written consent of Pryor, McClendon or Underwriters'
Counsel, issue, directly or indirectly any press release or other communication
or hold any press conference with respect to the Company or its activities or
the offering contemplated hereby, other than trade releases issued in the
ordinary course of the Company's business consistent with past practices.

               (u)  For a period equal to the lesser of (i) five (5) years from
the date hereof, and (ii) the sale to the public of the Representative's
Securities (or the shares of Common Stock issuable upon exercise of the
Representative's Securities), the Company will not take any action or actions
which may prevent or disqualify the Company's use of an appropriate form for the
registration under the Act of the Representative's Securities (or the shares of
Common Stock issuable upon exercise of the Representative's Securities).

               (v)  The Company agrees that it shall use its best efforts, which
shall include, but shall not be limited to, the solicitation of proxies, to
elect one (1) designee agreed-upon by Pryor, McClendon and National to the
Company's Board of Directors for a period of five (5) years following the
Closing Date, provided that such designee is reasonably acceptable to the
Company and that such director may be excluded from consideration of certain
confidential matters which, in the good faith judgment of a majority of the
other directors, make such director's presence not appropriate.

<PAGE>
 
               (w)  The Company agrees that within forty-five (45) days after
the Closing Date it shall retain a public relations firm which is reasonably
acceptable to Pryor, McClendon and National. Provided that such public relations
firm performs in a commercially reasonable and satisfactory manner, the Company
shall keep such public relations firm and any replacement for a total period of
two (2) years from the Closing Date. Any replacement public relations firm shall
be retained only with the consent of Pryor, McClendon and National, which shall
not be unreasonably withheld.

               (x)  The Company agrees that any and all future transactions
between the Company and any of its officers, directors, principal stockholders
and the affiliates of the foregoing persons will be on terms no less favorable
to the Company than could reasonably be obtained in arm's length transactions
with independent third parties, and that any such transactions also be approved
by a majority of the Company's outside independent directors disinterested in
the transaction.

               (y)  The Company shall prepare and deliver, at the Company's sole
expense, to Pryor, McClendon and National within the one hundred and twenty
(120) day period after the later of the effective date of the Registration
Statement and the latest Option Closing Date, as the case may be, one bound
volume each containing all correspondence with regulatory officials, agreements,
documents and all other materials in connection with the offering to which such
Registration Statement relates as requested by the Underwriters' Counsel.

          5.  Payment of Expenses.

disbursements of Underwriters' Counsel, less any amounts already paid pursuant
to Section 5(c) hereof provided that Pryor, McClendon and National shall notify
the Company of any single expense or any series of similar expenses which in the
aggregate exceed $5,000 (provided further that such notice requirement shall not
apply to Pryor, McClendon's and National's actual out-of-pocket legal expenses).

               (c)  The Company further agrees that, in addition to the expenses
payable pursuant to subsection (a) of this Section 5, it will pay to the
Representatives on the Closing Date by certified or bank cashier's check or, at

2(b) hereof, the Company further agrees to pay to the Representatives on each
Option Closing Date (by certified or bank cashier's check or, at the
Representative's election, by deduction from the proceeds of the offering) a
non-accountable expense allowance equal to three percent (3%) of the gross

          6.  Conditions of the Underwriters' Obligations.  The obligations of
              -------------------------------------------                     
the Underwriters hereunder shall be subject to the continuing accuracy of the
representations and warranties of the Company herein as of the date hereof and
as of the Closing Date and each Option Closing Date, if any, as if they had been
made on and as of the Closing Date or each Option Closing Date, as the case may
be; the accuracy on and as of the Closing Date or Option Closing Date, if any,
of the statements of officers of the Company made pursuant to the provisions
hereof; and the performance by the Company on and as of the Closing Date and

to the following further conditions:

               (a)  The Registration Statement shall have become effective not
later than 5:00 p.m., New York City time, on the date prior to the date of this

Commission for additional information shall have been complied with to the
reasonable satisfaction of Underwriters' Counsel. If the Company has elected to
rely upon Rule 430A of the Regulations, the price of the Shares and Warrants and
any price-related information previously omitted from the effective Registration
Statement pursuant to such Rule 430A shall have been transmitted to the
Commission for filing pursuant to Rule 424(b) of the Regulations within the
prescribed time period, and prior to the Closing Date the Company shall have
provided evidence satisfactory to the Representatives of such timely filing, or

the Registration Statement, or any amendment thereto, contains an untrue
statement of fact which, in the Representative's reasonable opinion, is
material, or omits to state a fact which, in the Representative's reasonable
opinion, is material and is required to be stated therein or is necessary to
make the statements therein not misleading, or that the Prospectus, or any
supplement thereto, contains an untrue statement of fact which, in the
Representative's reasonable opinion, is material, or omits to state a fact
which, in the Representative's reasonable opinion, is material and is required
to be stated therein or is necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

               (c)  On or prior to the Closing Date, the Underwriters shall have
received from Underwriters' Counsel such opinion or opinions with respect to the
organization of the Company, the validity of the Securities, the Registration
Statement, the Prospectus and other related matters as the Representatives may
reasonably request and Underwriters' Counsel shall have received from the
Company such papers and information as they request to enable them to pass upon
such matters.

the favorable opinion of Fenwick & West LLP ("Fenwick & West"), counsel to the
Company, dated the Closing Date, addressed to the Underwriters and in form and

               jurisdiction of incorporation, (B) is duly qualified and licensed
               and in good standing as a foreign corporation in each
               jurisdiction in which its ownership or leasing of any properties
               or the character of its operations requires such qualification or
               licensing, except where the failure to be so qualified or
               licensed would not have a material adverse effect on the
               Company's business and (C) to such counsel's knowledge, has all
               requisite corporate power and authority and has obtained any and

                  (ii) except as described in the Prospectus and except for A&R
              technology, a currently inactive subsidiary organized in the
              former Soviet Union which, to such counsel's knowledge, does not
              currently engage in any substantial activities, to such counsel's
              knowledge, the Company does not own an interest in any
              corporation, limited liability company, partnership, joint
              venture, trust or other business entity;

                  (iii) to such counsel's knowledge, the Company has a duly
              authorized, issued and outstanding capitalization as set forth in
              the Prospectus, and any amendment or supplement thereto, under
              "Capitalization" and "Description of Capital Stock," and to the
              knowledge of such counsel, the Company is not a party to or bound
              by any instrument, agreement or other arrangement providing for it
              to issue any capital stock, rights, warrants, options or other
              securities, except for this Agreement, the Warrant Agreement, the
              Representatives' Warrant Agreement, and as described in the
              Prospectus.  The Securities and all other securities issued or
              issuable by the Company which will be outstanding after the
              Closing Date conform in all material respects to the statements
              with respect thereto contained in the Registration Statement and
              the Prospectus.  All issued and outstanding securities of the
              Company have been duly authorized and validly issued and are fully
              paid and nonassessable; and none of such securities were issued in
              violation of the preemptive rights known to such counsel of any
              holders of any security of the Company.  The Securities to be sold
              by the Company hereunder, under the Warrant Agreement, and under
              the Representatives' Warrant Agreement are not and will not be
              subject to any preemptive or other similar rights of any
              stockholder known to such counsel, have been duly authorized and,
              when issued, paid for and delivered in accordance with their
              terms, will be validly issued, fully paid and nonassessable and
              will conform in all material respects to the description thereof
              contained in the Prospectus; all corporate action required to be
              taken for the authorization, issue and sale of the Securities has
              been duly and validly taken; and the certificates representing the
              Securities are in due and proper form.  The Representatives'
              Warrants and the Warrants constitute valid, binding and
              enforceable obligations of the Company to issue and sell, upon
              exercise thereof and payment therefor, the number and type of
              securities of the Company called for thereby (except as such
              enforceability may be limited by applicable bankruptcy,
              insolvency, reorganization, moratorium or other laws of general
              application relating to or affecting enforcement of creditors'
              rights and the application of equitable principles in any action,
              legal or equitable, and except as rights to indemnity or
              contribution may be limited by applicable law).  Upon the issuance
              and delivery pursuant to this Agreement of the Securities to be
              sold by the Company, the Company will convey, against payment
              therefor as provided herein, to the Underwriters and the
              Representatives, respectively, good and marketable title to the
              Securities

              free and clear of any adverse claim, provided that the
              Underwriters are purchasing such Securities in good faith and
              without notice of any adverse claim;

                  (iv) based solely upon the oral advice of the Staff of the
              Commission, the Registration Statement is effective under the Act,
              and, if applicable, filing of all pricing information has been
              timely made in the appropriate form under Rule 430A, and no stop
              order suspending the use of any preliminary prospectus, the
              Registration Statement or Prospectus or any part of any thereof or
              suspending the effectiveness of the Registration Statement has
              been issued and no proceedings for that purpose have been
              instituted or are pending or, to such counsel's knowledge,
              threatened or contemplated under the Act;

                  (v) each of any preliminary prospectus, the Registration
              Statement, and the Prospectus and any amendments or supplements
              thereto (other than the financial statements and other financial
              and statistical data included therein as to which no opinion need
              be rendered) comply as to form in all material respects with the
              requirements of the Act and the Regulations.  Such counsel shall
              state that such counsel has participated in conferences with
              officers and other representatives of the Company and the
              Representatives and representatives of the independent public
              accountants for the Company, at which conferences the contents of
              any preliminary prospectus, the Registration Statement, the
              prospectus, and any amendments or supplements thereto were
              discussed, and, although such counsel is not passing upon and does
              not assume any responsibility for the accuracy, completeness or
              fairness of the statements contained in the preliminary
              prospectus, the Registration Statement and Prospectus, and any
              amendments or supplements thereto, on the basis of the foregoing,
              no facts have come to the attention of such counsel which lead
              them to believe that either the Registration Statement or any
              amendment thereto, at the time such Registration Statement or
              amendment became effective or the Preliminary Prospectus or
              Prospectus or amendment or supplement thereto as of the date of
              such opinion contained any untrue statement of a material fact or
              omitted to state a material fact required to be stated therein or
              necessary to make the statements therein not misleading (it being
              understood that such counsel need express no opinion with respect
              to the financial statements and schedules and other financial and
              statistical data included in the Preliminary Prospectus, the
              Registration Statement or Prospectus, and any amendments or
              supplements thereto);

                  (vi) to such counsel's knowledge, (A) there are no agreements,
              contracts or other documents required by the Act to be described
              in the Registration Statement and the Prospectus and filed as
              exhibits to the Registration Statement other than those described
              in the Registration

              Statement and the Prospectus and filed as exhibits thereto; (B)
              the descriptions in the Registration Statement and the Prospectus
              and any supplement or amendment thereto of contracts and other
              agreements to which the Company is a party that are expressly
              referred to in the Registration Statement and the Prospectus, are
              accurate in all material respects; (C) there is not pending or
              overtly threatened against the Company any action, arbitration,
              suit, proceeding, litigation, governmental or other proceeding
              (including, without limitation, those having jurisdiction over
              environmental or similar matters), domestic or foreign, which (x)
              is required by the Regulations to be disclosed in the Registration
              Statement which is not so disclosed (and such proceedings as are
              summarized in the Registration Statement are accurately summarized
              in all material respects), (y) questions the validity of the
              capital stock of the Company or this Agreement, the Warrant
              Agreement, or the Representatives' Warrant Agreement, or of any
              action taken or to be taken by the Company pursuant to or in
              connection with any of the foregoing; and (D) there is no action,
              suit or proceeding pending or overtly threatened against the
              Company before any court or arbitrator or governmental body,
              agency or official in which there is a reasonable possibility of
              an adverse decision which may result in a material adverse change
              in the financial condition, business, operations or results of
              operations of the Company, which could reasonably be expected to
              materially adversely effect the present or prospective ability of
              the Company to perform its obligations under this Agreement, the
              Warrant Agreement or the Representatives' Warrant Agreement, or
              which in any manner questions the validity or enforceability of
              this Agreement, the Warrant Agreement or the Representatives'
              Warrant Agreement;

                  (vii) the Company has the corporate power and authority to
              enter into each of this Agreement, the Warrant Agreement, and the
              Representatives' Warrant Agreement and to consummate the
              transactions provided for therein; and each of this Agreement, the
              Warrant Agreement, and the Representatives' Warrant Agreement has
              been duly authorized, executed and delivered by the Company.  Each
              of this Agreement, the Warrant Agreement, and the Representatives'
              Warrant Agreement, assuming due authorization, execution and
              delivery by each other party thereto, constitutes a legal, valid
              and binding obligation of the Company enforceable against the
              Company in accordance with its terms (except as the enforceability
              thereof may be limited by applicable bankruptcy, insolvency,
              reorganization, moratorium or other laws of general application
              relating to or affecting enforcement of creditors' rights and the
              application of equitable principles in any action, legal or
              equitable, except as rights to indemnity or contribution may be
              limited by applicable law, and except for other customary
              exceptions set forth in such counsel's opinion), and to such
              counsel's knowledge none of the Company's execution, delivery or
              performance of this Agreement, the Warrant Agreement, and the
              Representatives' Warrant Agreement, the

              consummation by the Company of the transactions contemplated
              herein or therein, or the conduct of the Company's business as
              described in the Registration Statement, the Prospectus, and any
              amendments or supplements thereto conflicts with or results in any
              material breach or violation of any of the terms or provisions of,

              or imposition of any material lien, charge, claim, encumbrance,
              pledge, security interest, defect or other restriction or equity
              of any kind whatsoever upon, any property or assets (tangible or
              intangible) of the Company pursuant to the terms of (A) the
              articles of incorporation or by-laws of the Company, as amended,

              voting trust agreement, stockholders' agreement, note, loan or
              credit agreement or any other agreement or instrument identified
              by the Company to such counsel as material to the business of the
              Company, to which the Company is a party or by which it is bound,
              or (C) any federal, state or local statute, rule or regulation
              known to such counsel to be applicable to the Company or any
              judgment, decree or order known to such counsel of any arbitrator,
              court, regulatory body or administrative agency or other
              governmental agency or body (including, without limitation, those
              having jurisdiction over environmental or similar matters),
              domestic or foreign, having jurisdiction over the Company or any
              of its activities or properties, in each case where such conflict,
              breach, violation or default would have a material adverse effect
              on the Company's business;

                  (viii)  no consent, approval, authorization or order, and no
              filing with, any court, regulatory body, government agency or
              other body (other than such as may be required under Blue Sky
              laws, as to which no opinion need be rendered or under federal
              securities laws, as to which no opinion need be rendered pursuant
              to this subsection (viii)) is required in connection with the
              issuance of the Securities pursuant to the Prospectus and the
              Registration Statement, the performance of this Agreement, the
              Warrant Agreement, and the Representatives' Warrant Agreement, and
              the transactions contemplated hereby and thereby;

                  (ix) to such counsel's knowledge, the properties of the
              Company conform in all material respects to the description
              thereof contained in the Registration Statement and the
              Prospectus;

                  (x) to the knowledge of such counsel, and except as disclosed
              in the Registration Statement and the Prospectus, (A) the Company
              is not in material breach of, or in material default under, any
              term or provision of any license, contract, agreement, indenture,
              mortgage, installment sale agreement, deed of trust, lease, voting
              trust agreement, stockholders' agreement, note, loan or credit
              agreement or any other agreement or instrument evidencing an

              each case where such breach or default would have a material
              adverse effect on the business of the Company, and (B) the Company
              is not in material violation of any term or provision of its
              articles of incorporation or by-laws, as amended, or in material
              violation of any franchise, license, permit, judgment, decree,
              order, statute, rule or regulation known to such counsel to be
              applicable to the Company, in each case where such breach, default
              or violation would have a material adverse effect on the Company's
              business;

                  (xi)  the statements in the Prospectus under "Dividend
              Policy," "Description of Capital Stock," and "Shares Eligible for
              Future Sale" have been reviewed by such counsel, and insofar as
              they refer to statements of law, descriptions of statutes,
              licenses, rules or regulations or legal conclusions, are correct
              in all material respects;

              the outstanding securities and the contracts furnished to such
              counsel by the Company, except as disclosed in the Registration
              Statement and Prospectus no person, corporation, trust,
              partnership, association or other entity has the right to include

              the Option Closing Date, as the case may be, other than in the

              loss or damage to its property or assets, whether or not insured,

              affiliated party of any of the foregoing which is required to be

              been set forth, and (g) there has occurred no event required to be

              (h) By the Closing Date, the Underwriters will have received

              (i) At the time this Agreement is executed, the Underwriters shall
have received a letter, dated such date, addressed to the Underwriters in form
and substance satisfactory in all respects (including the non-material nature of
the changes or decreases, if any, referred to in clause (iii) below) to the
Underwriters and Underwriters' Counsel, from Grant Thornton:

                  (i)  confirming that they are independent certified public
              accountants with respect to the Company within the meaning of the
              Act and the applicable Rules and Regulations;

                                      -27-
<PAGE>
 
                  (ii) stating that it is their opinion that the financial
              statements of the Company included in the Registration Statement
              comply as to form in all material respects with the applicable
              accounting requirements of the Act and the Regulations thereunder
              and that the Representatives may rely upon the opinion of Grant
              Thornton with respect to the financial statements and supporting
              schedules included in the Registration Statement;

                  (iii) stating that, on the basis of a limited review which
              included a reading of the latest available unaudited interim
              financial statements of the Company (with an indication of the
              date of the latest available unaudited interim financial
              statements), a reading of the latest available minutes of the
              stockholders and board of directors and the various committees of
              the board of directors of the Company, consultations with officers
              and other employees of the Company responsible for financial and
              accounting matters and other specified procedures and inquiries,
              nothing has come to their attention which would lead them to
              believe that (A) the unaudited financial statements of the Company
              included in the Registration Statement, if any, do not comply as
              to form in all material respects with the applicable accounting
              requirements of the Act and the Regulations or are not fairly
              presented in conformity with generally accepted accounting
              principles applied on a basis substantially consistent with that
              of the audited financial statements of the Company included in the
              Registration Statement, or (B) at a specified date not more than
              five (5) days prior to the effective date of the Registration
              Statement, there has been any change in the capital stock or
              material increase in long-term debt of the Company, or any
              material decrease in the stockholders' equity or net current
              assets or net assets of the Company as compared with amounts shown
              in the most recent balance sheet included in the Registration
              Statement, other than as set forth in or contemplated by the
              Registration Statement, or, if there was any change or decrease,
              setting forth the amount of such change or decrease.

                  (iv) stating that they have compared specific dollar amounts,
              numbers of shares, percentages of revenues and earnings,
              statements and other financial information pertaining to the
              Company set forth in the Prospectus in each case to the extent
              that such amounts, numbers, percentages, statements and
              information may be derived from the general accounting records,
              including work sheets, of the Company and excluding any questions
              requiring an interpretation by legal counsel, with the results
              obtained from the application of specified readings, inquiries and
              other appropriate procedures (which procedures do not constitute
              an examination in accordance with generally accepted auditing
              standards) set forth in the letter and found them to be in
              agreement; and

                                      -28-
<PAGE>
 
               (v) statements as to such other material matters incident to the
          transaction contemplated hereby as the Representatives may reasonably
          request.

          (j) At the Closing Date and each Option Closing Date, if any, the
Underwriters shall have received from Grant Thornton a letter, dated as of the
Closing Date or the Option Closing Date, as the case may be, to the effect that
they reaffirm that statements made in the letter furnished pursuant to
Subsection (i) of this Section 6, except that the specified date referred to
shall be a date not more than five (5) days prior to the Closing Date or the
Option Closing Date, as the case may be, and, if the Company has elected to rely
on Rule 430A of the Rules and Regulations, to the further effect that they have
carried out procedures as specified in clause (iv) of Subsection (i) of this
Section 6 with respect to certain amounts, percentages and financial information
as specified by the Representatives and deemed to be a part of the Registration
Statement pursuant to Rule 430A(b) and have found such amounts, percentages and
financial information to be in agreement with the records specified in such
clause (iv).

          (k) On each of Closing Date and Option Closing Date, if any, there
shall have been duly tendered to the Representatives for the several
Underwriters' accounts the appropriate number of Securities.

          (l) No order suspending the sale of the Securities in any jurisdiction
designated by the Representatives pursuant to subsection (e) of Section 4 hereof
shall have been issued on either the Closing Date or the Option Closing Date, if
any, and no proceedings for that purpose shall have been instituted or shall be
contemplated.

          (m) On or before the Closing Date, the Company shall have executed and
delivered to the Representatives, (i) the Representatives' Warrant Agreement,
substantially in the form filed as Exhibit 4(b), to the Registration Statement,
in final form and substance satisfactory to the Representatives, and (ii) the
Representatives' Warrants in such denominations and to such designees as shall
have been provided to the Company.

          (n) On or before the Closing Date, the Common Stock shall have been
duly approved for quotation on the Nasdaq SmallCap Market.

          (o) On or before the Closing Date, there shall have been delivered to
the Representatives all of the Lock-up Agreements that have been executed and
delivered to the Company in final form and substance satisfactory to
Underwriters' Counsel.

          If any condition to the Underwriters' obligations hereunder to be
fulfilled prior to or at the Closing Date or the relevant Option Closing Date,
as the case may be, is not so fulfilled, the Representatives may terminate this
Agreement or, if the Representatives so elect, they may waive any such
conditions which have not been fulfilled or extend the time for their
fulfillment.

          7. Indemnification.
             --------------- 

               (a) The Company agrees to indemnify and hold harmless each of the
Underwriters (for purposes of this Section 7 "Underwriters" shall include the
officers, directors, partners, employees, and counsel of the Underwriters,
including specifically each person who may be substituted for an Underwriter as
provided in Section 11 hereof), and each person, if any, who controls the
Underwriter ("controlling person") within the meaning of Section 15 of the Act
or Section 20(a) of the Exchange Act, from and against any and all loss,
liability, claim, damage, and expense whatsoever (including, but not limited to,
reasonable attorneys' fees and any and all reasonable expense whatsoever
incurred in investigating, preparing or defending against any litigation,
commenced or threatened, or any claim whatsoever and any and all amounts paid in
settlement of any claim or litigation provided that the indemnified persons may
not agree to any such settlement without the prior written consent of the
Company), as and when incurred, arising out of, based upon or in connection with
(i) any untrue statement or alleged untrue statement of a material fact
contained (A) in any preliminary prospectus, the Registration Statement or the
Prospectus (as from time to time amended and supplemented); or (B) in any
application or other document or communication (in this Section 7 collectively
called "application") executed by or on behalf of the Company or based upon
written information furnished by or on behalf of the Company in any jurisdiction
in order to qualify the Securities under the securities laws thereof or filed
with the Commission, any state securities commission or agency, The Nasdaq Stock
Market, Inc. or any securities exchange; or any omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading (in the case of the Prospectus, in the light
of the circumstances under which they were made), unless such statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company with respect to any Underwriter by or on behalf of such
Underwriter expressly for use in any preliminary prospectus, the Registration
Statement or Prospectus, or any amendment thereof or supplement thereto, or in
any application, as the case may be; or (ii) any breach of any representation,
warranty, covenant or agreement of the Company contained in this Agreement.  The
indemnity agreement in this subsection (a) shall be in addition to any liability
which the Company may have at common law or otherwise.

               (b) Each of the Underwriters agrees severally, but not jointly,
to indemnify mutual: employees, counsel and hold harmless the Company, each of
its directors, employees, each of its officers who has signed the Registration
Statement, counsel to the Company, and each other person, if any, who controls
the Company, within the meaning of the Act, to the same extent as the foregoing
indemnity from the Company to the Underwriters but only with respect to
statements or omissions, if any, made in any preliminary prospectus, the
Registration Statement or Prospectus or any amendment thereof or supplement
thereto or in any application made in reliance upon, and in strict conformity
with, written information furnished to the Company with respect to any
Underwriter by such Underwriter or the Representatives expressly for use in such
preliminary prospectus, the Registration Statement or Prospectus or any
amendment thereof or supplement thereto or in any such application. The Company
acknowledges that the statements with respect to the public offering of the
Securities set forth under the heading "Underwriting" and the stabilization
legend in the Prospectus have been furnished by the Underwriters expressly

                                      -30-
<PAGE>
 
for use therein and constitute the only information furnished in writing by or
on behalf of the Underwriters or the Representatives for inclusion in the
Prospectus.

               (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, suit or proceeding, such
indemnified party shall, if a claim in respect thereof is to be made against one
or more indemnifying parties under this Section 7, notify each party against
whom indemnification is to be sought in writing of the commencement thereof (but
the failure to so notify an indemnifying party shall not relieve it from any
liability which it may have otherwise or which it may have under this Section 7,
except to the extent that it has been prejudiced in any material respect by such
failure). In case any such action is brought against any indemnified party, and
it notifies an indemnifying party or parties of the commencement thereof, the
indemnifying party or parties will be entitled to participate therein, and to
the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to
assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such
case, but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by the indemnifying parties in connection with
the defense of such action at the expense of the indemnifying party, (ii) the
indemnifying parties shall not have employed counsel reasonably satisfactory to
such indemnified party to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have been advised in writing by counsel that
a conflict of interest exists between the indemnifying party and the indemnified
parties making representation of such parties by the same counsel inappropriate
(in which case the indemnifying parties shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties), in any of
which events the reasonable fees and expenses of one additional counsel shall be
borne by the indemnifying parties. In no event shall the indemnifying parties be
liable for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
Anything in this Section 7 to the contrary notwithstanding, an indemnifying
party shall not be liable for any settlement of any claim or action effected
without its written consent; provided, however, that such consent was not
                             --------  -------                           
unreasonably withheld.

               (d) In order to provide for just and equitable contribution in
any case in which (i) an indemnified party makes claim for indemnification
pursuant to this Section 7, but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
the express provisions of this Section 7 provide for indemnification in such
case, or (ii) contribution under the Act may be required on the part of any
indemnified party, then each indemnifying party shall contribute to the amount
paid as a result of such losses, claims, damages, expenses or liabilities (or
actions in respect thereof) (A) in such proportion as is appropriate to reflect
the relative benefits received by each of the contributing parties, on the one
hand, and the party to be

                                      -31-
<PAGE>
 
indemnified on the other hand, from the offering of the Securities or (B) if the
allocation provided by clause (A) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of each of the
contributing parties, on the one hand, and the party to be indemnified on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages, expenses or liabilities, as well as any other relevant
equitable considerations. In any case where the Company is a contributing party
and the Underwriters are the indemnified party, the relative benefits received
by the Company on the one hand, and the Underwriters, on the other, shall be
deemed to be in the same proportion as the total net proceeds from the offering
of the Securities (before deducting expenses other than underwriting discounts
and commissions) bear to the total underwriting discounts received by the
Underwriters hereunder, in each case as set forth in the table on the Cover Page
of the Prospectus. Relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Underwriters, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, expenses or
liabilities (or actions in respect thereof) referred to above in this
subdivision (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subdivision (d) the Underwriters shall not be required to contribute any amount
in excess of the underwriting discount applicable to the Securities purchased by
the Underwriters hereunder. No person guilty of fraudulent misrepresentation
(within the meaning of Section 12(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 7, each person, if any, who
controls the Company within the meaning of the Act, each officer of the Company
who has signed the Registration Statement, and each director of the Company
shall have the same rights to contribution as the Company, subject in each case
to this subparagraph (d). Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding
against such party in respect to which a claim for contribution may be made
against another party or parties under this subparagraph (d), notify such party
or parties from whom contribution may be sought, but the omission so to notify
such party or parties shall not relieve the party or parties from whom
contribution may be sought from any obligation it or they may have hereunder or
otherwise than under this subparagraph (d), or to the extent that such party or
parties were not adversely affected by such omission. The contribution agreement
set forth above shall be in addition to any liabilities which any indemnifying
party may have at common law or otherwise.

          8.  Representations and Agreements to Survive Delivery.  All
              --------------------------------------------------      
representations, warranties and agreements contained in this Agreement or
contained in certificates of officers of the Company submitted pursuant hereto,
shall be deemed to be representations, warranties and agreements of the Company
at the Closing Date and the Option Closing Date, as the case may be, and such
representations, warranties and agreements of the Company and the respective
indemnity and contribution agreements contained in Section 7 hereof shall remain
operative and in full force and effect regardless of any investigation made by
or on behalf of any Underwriter, 

                                      -32-
<PAGE>
 
the Company, any controlling person of either the Underwriter or the Company,
and shall survive termination of this Agreement or the issuance and delivery of
the Securities to the Underwriters and the Representatives, as the case may be.

          9. Effective Date.
             -------------- 

               (a) This Agreement shall become effective at 5:00 p.m., New York
City time, on the date hereof. For purposes of this Section 9, the Securities to
be purchased hereunder shall be deemed to have been so released upon the earlier
of dispatch by the Representatives of telegrams to securities dealers releasing
such shares for offering or the release by the Representatives for publication
of the first newspaper advertisement which is subsequently published relating to
the Securities.

          10.  Termination.
               ----------- 

               (a) Subject to subsection (b) of this Section 10, the
Representatives shall have the right to terminate this Agreement, if between the
date of this Agreement and the Closing Date or the Option Closing Date, as the
case may be, (i) if any domestic or international event or act or occurrence has
materially disrupted, or in the Representative's reasonable opinion will in the
immediate future have a material and adverse effect on the securities markets
generally; or (ii) any material adverse change in the financial markets shall
have occurred; or (iii) if trading on the New York Stock Exchange, the American
Stock Exchange, or in the over-the-counter market shall have been suspended, or
minimum or maximum prices for trading shall have been fixed, or maximum ranges
for prices for securities shall have been required on the over-the-counter
market by the NASD or by order of the Commission or any other government
authority having jurisdiction; or (iv) if the United States shall have become
involved in a war or major hostilities, or if there shall have been an
escalation in an existing war or major hostilities or a national emergency shall
have been declared in the United States; or (v) if a banking moratorium has been
declared by a state or federal authority; or (vi) if the Company shall have
sustained a loss material to the Company by fire, flood, accident, hurricane,
earthquake, theft, sabotage or other calamity or malicious act which, whether or
not such loss shall have been insured, will, in the Representative's opinion,
make it inadvisable to proceed with the delivery of the Securities; or (viii) if
there shall have been such a material adverse change in the prospects or
conditions of the Company, or such material adverse effect in the securities
markets generally, political or economic conditions, in the United States or
elsewhere as in the Representative's good faith judgment would make it
inadvisable to proceed with the offering, sale and/or delivery of the
Securities.

               (b) If this Agreement is terminated by the Representatives in
accordance with any of the provisions of Section 6, Section 10(a) or Section 11,
the Company shall promptly reimburse and indemnify the Underwriters pursuant to
Section 5(b) hereof.  Notwithstanding any contrary provision contained in this
Agreement, any election hereunder or any termination of this Agreement
(including, without limitation, pursuant to Sections 6, 10, 11 and 12 hereof),
and whether or not this Agreement is otherwise carried out, the provisions of
Section 5 and Section 7 shall not be in any way affected by such election or
termination or failure to carry out the terms of this Agreement or any part
hereof.

                                      -33-
<PAGE>
 
          11.  Substitution of Underwriters.  If one or more of the Underwriters
               ----------------------------                                     
shall fail (otherwise than for a reason sufficient to justify the termination of
this Agreement under the provisions of Section 6, Section 10 or Section 12
hereof) to purchase the Securities which it or they are obligated to purchase on
such date under this Agreement (the "Defaulted Securities"), the Representatives
shall have the right, within 24 hours thereafter, to make arrangement for one or
more of the non-defaulting Underwriters, or any other underwriters, to purchase
all, but not less than all, of the Defaulted Securities in such amounts as may
be agreed upon and upon the terms herein set forth.  If, however, the
Representatives shall not have completed such arrangements within such 24-hour
period, then:

               (a) if the number of Defaulted Securities does not exceed 10% of
the total number of Firm Securities to be purchased on such date, the non-
defaulting Underwriters shall be obligated to purchase the full amount thereof
in the proportions that their respective underwriting obligations hereunder bear
to the underwriting obligations of all non-defaulting Underwriters, or

               (b) if the number of Defaulted Securities exceeds 10% oF the
total number of Firm Securities to be purchased on such date, this Agreement
shall terminate without liability on the part of any non-defaulting
Underwriters.

               No action taken pursuant to this Section shall relieve any
defaulting Underwriter from liability in respect of any default by such
Underwriter under this Agreement.

               In the event of any such default which does not result in a
termination of this Agreement, the Representatives shall have the right to
postpone the Closing Date for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or Prospectus or in
any other documents or arrangements.

          12.  Default by the Company.  If the Company shall fail at the Closing
               ----------------------                                           
Date or any Option Closing Date, as applicable, to sell and deliver the number
of Securities which it is obligated to sell hereunder on such date, then this
Agreement shall terminate (or, if such default shall occur with respect to any
Option Securities to be purchased on an Option Closing Date, the Underwriters
may at the Representative's option, by notice from the Representatives to the
Company, terminate the Underwriters' obligation to purchase Option Securities
from the Company on such date) without any liability on the part of any non-
defaulting party other than pursuant to Section 5, Section 7 and Section 10
hereof.  No action taken pursuant to this Section shall relieve the Company from
liability, if any, in respect of such default.

          13.  Notices.  All notices and communications hereunder, except as
               -------

to the public pursuant to the terms and provisions of the Underwriting
Agreement. The shares of Common Stock and the Redeemable Warrants issuable upon
exercise of the Representatives' Warrants are sometimes hereinafter referred to

          2.  Representatives' Warrant Certificates.  The Representatives'
              -------------------------------------

Representatives' Warrant Certificate are exercisable at the option of the Holder
thereof, in whole or in part (but not as to fractional shares of Common Stock
and/or Redeemable Warrants underlying the Representatives' Warrants).
Representatives' Warrants may be exercised to purchase all or part of the shares
of Common Stock together with an equal or unequal number of the Redeemable
Warrants represented thereby. In the case of the purchase of less than all of
the shares of Common Stock and/or Redeemable Warrants purchasable under any
Representatives' Warrant Certificate, the Company shall cancel said
Representatives' Warrant Certificate upon the surrender thereof and shall

thereunder.

          5.  Issuance of Certificates.  Upon the exercise of the

event within five (5) business days thereafter) without charge to the Holder
thereof including, without limitation, any tax which may be payable in respect
of the issuance thereof, and such certificates shall (subject to the provisions

name of, or in such names as may be directed by, the Holder thereof; provided,
however, that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
such certificates in a name other than that of the Holder and the Company shall
not be required to issue or deliver such certificates unless or until the person
or persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

          The Representatives' Warrant Certificates and the certificates
representing the shares of Common Stock and/or Redeemable Warrants or other
securities, property or rights issued upon exercise of the Representatives'
Warrant shall be executed on behalf of the Company by the manual or facsimile
signature of the then present President or any Vice President of the Company
under its corporate seal reproduced thereon, attested to by the manual or
facsimile signature of the then present Secretary or any Assistant Secretary of
the Company.  Representatives' Warrant Certificates shall be dated the date of

or transfer.

          6.  Transfer of Representatives' Warrant.  The Representatives'

Warrant may not be sold, transferred, assigned, hypothecated or otherwise
disposed of, in whole or in part, for the term of the Representatives' Warrant,

          ACCORDANCE WITH THE REPRESENTATIVES' WARRANT AGREEMENT
          REFERRED TO HEREIN.


              1.1.1 Piggyback Registration.  If, at any time commencing after 
                    ----------------------
the effective date of the Registration Statement and expiring five (5) years
thereafter, the Company proposes to register any of its securities under the Act
(other than in connection with a merger or pursuant to Form S-4 or Form S-8) it
will give written notice by registered mail, at least twenty (20) days prior to
the filing of each such registration statement, to the Holders of the
Representatives' Warrants and/or the Warrant Shares of its intention to do so.
If any of the Holders of the Representatives' Warrants and/or Warrant Shares
notify the Company within ten (10) days after mailing of any such notice of its
or their desire to include any such securities in such proposed registration
statement, the Company shall afford such Holders of the Representatives'
Warrants and/or Warrant Shares the opportunity to have any such Representatives'
Warrants and/or Warrant Shares registered under such registration statement.  In
the event that the managing underwriter for said offering advises the Company in
writing that in its opinion the number of securities requested to be included in
such registration exceeds the number which can be sold in such offering without
causing a diminution in the offering price or otherwise adversely affecting the
offering, the Company will include in such registration (a) first, the

                                                             -----     
Representatives' Warrants and/or Warrant Shares requested to be 

                                      -8-

included in such registration which in the opinion of such underwriter can be
sold, pro rata among all proposed selling shareholders.
      --- ----

          Notwithstanding the provisions of this Section 9.2, the Company shall
                                                 -------                       
have the right at any time after it shall have given written notice pursuant to
this Section 9.2 (irrespective of whether a written request for inclusion of any
     -------                                                                    
such securities shall have been made) to elect not to file any such proposed
registration statement or to withdraw the same after the filing but prior to the
effective date thereof.

Representatives' Warrants and/or Warrant Shares representing a "Majority" (as
hereinafter defined) of the Representatives' Warrants and/or Warrant Shares

under Section 9.2 hereof), exercisable by written notice to the Company, to have

documents, including a prospectus, as may be necessary in the opinion of both
counsel for the Company and counsel for the Holders, in order to comply with the
provisions of the Act, so as to permit a public offering and sale by such
Holders and any other Holders of the Representatives' Warrant and/or Warrant
Shares who notify the Company within fifteen (15) days after the Company mails

"Requesting Holders") of their respective Warrant Shares for the earlier of (i)
nine (9) consecutive months or (ii) until the sale of all of the Warrant Shares
requested to be registered by the Requesting Holders.

                    (b)  The Company covenants and agrees to give written notice
of any registration request under this Section 9.3 by any Holder or Holders
                                       -------
representing a Majority of the Representatives' Warrants and/or Warrant Shares

date of the receipt of any such registration request.

                    (c)  Intentionally omitted.

                    (d)  Notwithstanding anything to the contrary contained
herein, if the Company shall not have filed a registration statement for the
Warrant Shares within the time period specified in Section 9.4(a) hereof
                                                   -------
pursuant to the written notice specified in Section 9.3(a) of the Holders of a
                                            -------
Majority of the Representatives' Warrants and/or Warrant Shares, the Company, at
its option, may repurchase (i) any and all Warrant Shares at the higher of the
Market Price (as defined in Section 9.3(e)) per share of Common Stock on (x) the
                            -------

at such Market Price less the exercise price of such Representatives' Warrant.
Such repurchase shall be in immediately available funds and shall close within
two (2) days after the later of (i) the expiration of the period specified in
Section 9.4(a) or (ii) the delivery of the written notice of election specified
- -------
in this Section 9.3(d).
        -------

                    (e)  Definition of Market Price. As used herein, the phrase
                         --------------------------
"Market Price" at any date shall be deemed to be the last reported sale price,
or, in case no such reported sale takes place on such day, the average of the
last reported sale prices for the last three (3) trading days, in either case as
officially reported by the principal securities exchange on which 

                                     -11-
<PAGE>
 
the shares of Common Stock and/or Redeemable Warrants or Common Stock is listed

through The Nasdaq Stock Market, Inc. ("Nasdaq") or similar organization if
Nasdaq is no longer reporting such information, or if the shares of Common Stock

covenants and agrees as follows:

                    (a)  The Company shall use its best efforts to file a

in connection with all registration statements filed pursuant to Sections 9.2
                                                                 --------
and 9.3(a) hereof including, without limitation, the Company's legal and
accounting fees, printing expenses, blue sky fees and expenses. The Holder(s)

                                                             -------

                    (c)  The Company will use its commercially reasonable
efforts to take all necessary action which may be required in qualifying or
registering the Warrant Shares included in a registration statement for offering
and sale under the securities or blue sky laws of such states as reasonably are
requested by the Holder(s), provided that the Company shall not be obligated to
execute or file any general consent to service of process or to qualify as a
foreign corporation to do business under the laws of any such jurisdiction.

                    (d)  The Company shall indemnify the Holder(s) of the
Warrant Shares to be sold pursuant to any registration statement and each
person, if any, who controls such Holders within the meaning of Section 15 of
the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended
("Exchange Act"), against all loss, claim, damage, expense or liability
(including all expenses reasonably incurred in investigating, preparing or
defending against any claim whatsoever) to which any of them may become subject
under the Act, the Exchange Act or otherwise, arising from such registration
statement but only to the same extent and with the same 

                                     -13-

effect as the provisions pursuant to which the Company has agreed to indemnify
each of the Underwriters contained in Section 7 of the Underwriting Agreement.
                                      -------

                    (e)  The Holder(s) of the Warrant Shares to be sold pursuant

Act or Section 20(a) of the Exchange Act, against all loss, claim, damage or

investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 7 of the
                                                               -------
Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company.

                    (f)  Nothing contained in this Agreement shall be construed
as requiring the Holder(s) to exercise their Representatives' Warrant prior to
the initial filing of any registration statement or the effectiveness thereof.

                    (g)  The Company shall not permit the inclusion of any
securities other than the Warrant Shares to be included in any registration

                                     -14-
<PAGE>
 
a registration statement filed pursuant to Section 9.3 hereof, without the prior
                                           -------                              
written consent of National Securities Corporation or as otherwise required by
the terms of any existing registration rights granted prior to the date of this
Agreement by the Company to the holders of any of the Company's securities.

                    (h)  The Company shall furnish to each Holder participating
in the offering and to each underwriter, if any, a signed counterpart, addressed
to such Holder or underwriter, of (i) an opinion of counsel to the Company,
dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, an opinion dated the date
of the closing under the underwriting agreement), and (ii) a "cold comfort"
letter dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, a letter dated the date
of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company's financial
statements included in such registration statement, in each case covering
substantially the same matters with respect to such registration statement (and
the prospectus included therein) and, in the case of such accountants' letter,
with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of
securities.

                    (i)  The Company shall as soon as practicable after the
effective date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings

                                     -15-

and covering a period of at least 12 consecutive months beginning after the
effective date of the registration statement.

                    (j)  The Company shall enter into an underwriting agreement
with the managing underwriters selected for such underwriting by Holders holding
a Majority of the Warrant Shares requested to be included in such underwriting,
which may be the Representative. Such agreement shall be satisfactory in form
and substance to the Company, each Holder and such managing underwriters, and
shall contain such representations, warranties and covenants by the Company and
such other terms as are customarily contained in agreements of that type used by
the managing underwriter. The Holders shall be parties to any underwriting
agreement relating to an underwritten sale of their Warrant Shares and may, at
their option, require that any or all the representations, warranties and
covenants of the Company to or for the benefit of such underwriters shall also
be made to and for the benefit of such Holders. Such Holders shall not be
required to make any representations or warranties to or agreements with the
Company or the underwriters except as they may relate to such Holders and their
intended methods of distribution.

                    (k)  For purposes of this Agreement, the term "Majority" in
reference to the Representatives' Warrants or Warrant Shares, shall mean in
excess of fifty percent (50%) of the then outstanding Representatives' Warrants
or Warrant Shares that (i) are not held by the Company, an affiliate, officer,
creditor, employee or agent thereof or any of their respective

                                     -16-

affiliates, members of their family, persons acting as nominees or in
conjunction therewith or (ii) have not been resold to the public pursuant to a
registration statement filed with the Commission under the Act.

          2.  Obligations of Holders.  It shall be a condition precedent to the
              ----------------------                                           
obligations of the Company to take any action pursuant to Section 9 hereof that
                                                          -------              
each of the selling Holders shall:

                    (a)  Furnish to the Company such information regarding
themselves, the Warrant Shares held by them, the intended method of sale or
other disposition of such securities, the identity of and compensation to be
paid to any underwriters proposed to be employed in connection with such sale or
other disposition, and such other information as may reasonably be required to
effect the registration of their Warrant Shares.

                    (b)  Notify the Company, at any time when a prospectus
relating to the Warrant Shares covered by a registration statement is required
to be delivered under the Act, of the happening of any event with respect to
such selling Holder as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing.

          3.  Adjustments to Exercise Price and Number of Securities.  The
              ------------------------------------------------------      
Exercise Price in effect at any time and the number and kind of securities
purchased upon the exercise of the Representatives' Warrant shall be subject to
adjustment from time to time only upon the happening of the following events:

              1.3.1 Stock Dividend, Subdivision and Combination.  In case the
                    -------------------------------------------              
Company shall (i) declare a dividend or make a distribution on its outstanding
shares of Common Stock in shares of Common Stock, (ii) subdivide or reclassify
its outstanding shares of Common Stock into a greater number of shares, or (iii)
combine or reclassify its outstanding shares of Common Stock into a smaller
number of shares, the Exercise Price in effect at the time of the record date
for such dividend or distribution or of the effective date of such subdivision,
combination or reclassification shall be adjusted so that it shall equal the
price determined by multiplying the Exercise Price by a fraction, the
denominator of which shall be the number of shares of Common Stock outstanding
after giving effect to such action, and the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such action.
Such adjustment shall be made successively whenever any event listed above shall
occur.

              1.3.2 Adjustment in Number of Securities.  Upon each adjustment of
                    ----------------------------------                          
the Exercise Price pursuant to the provisions of this Section 11, the number of
                                                      -------                  
Warrant Shares issuable upon the exercise at the adjusted Exercise Price of each
Representatives' Warrant shall be adjusted to the nearest number of whole shares
of Common Stock by multiplying a number 

                                     -18-
<PAGE>
 
equal to the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares issuable upon exercise of the Representatives'
Warrant immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

              1.3.3 Definition of Common Stock.  For the purpose of this
                    --------------------------                          
Agreement, the term "Common Stock" shall mean (i) the class of stock designated
as Common Stock in the Articles of Incorporation of the Company as amended as of
the date hereof, or (ii) any other class of stock resulting from successive
changes or reclassifications of such Common Stock consisting solely of changes
in par value, or from par value to no par value, or from no par value to par
value.

              1.3.4 Merger or Consolidation. In case of any consolidation of the
                    -----------------------
Company with, or merger of the Company into, another corporation (other than a
consolidation or merger which does not result in any reclassification or change
of the outstanding Common Stock), the corporation formed by such consolidation
or merger shall execute and deliver to the Holder a supplemental warrant
agreement providing that the Holder of each Representatives' Warrant then
outstanding or to be outstanding shall have the right thereafter (until the
expiration of such Representatives' Warrant) to receive, upon exercise of such
Representatives' Warrant, the kind and amount of shares of stock and other
securities and property receivable upon such consolidation or merger by a holder
of the number of shares of Common Stock for which such Representatives' Warrant
might have been exercised immediately prior to such consolidation, merger, sale
or transfer. Such supplemental warrant agreement shall provide for adjustments

                                     -19-
<PAGE>
 
which shall be identical to the adjustments provided in Section 11. The above
                                                        -------
provision of this subsection shall similarly apply to successive consolidations
or mergers.

              1.3.5 No Adjustment of Exercise Price in Certain Cases.  No
                    ------------------------------------------------     
adjustment of the Exercise Price shall be made:

                    (a)  Upon the issuance or sale of the Representatives'
Warrant or the Warrant Shares;

                    (b)  Upon the issuance or sale of Common Stock (or any other
security convertible, exercisable, or exchangeable into shares of Common Stock)
upon the direct or indirect conversion, exercise, or exchange of any options,
rights, warrants, or other securities or indebtedness of the Company outstanding
as of the date of this Agreement or granted pursuant to any stock option plan of
the Company in existence as of the date of this Agreement, pursuant to the terms
thereof; or

                    (c)  If the amount of said adjustment shall be less than two
cents ($.02) per share, provided, however, that in such case any adjustment that
would otherwise be required then to be made shall be carried forward and shall
be made at the time of and together with the next subsequent adjustment which,
together with any adjustment so carried forward, shall amount to at least two
cents ($.02) per Representatives' Warrant.

          4.  Exchange and Replacement of Representatives' Warrant Certificates.
              -----------------------------------------------------------------
Each Representatives' Warrant Certificate is exchangeable, without expense, upon
the surrender 

                                     -20-
<PAGE>
 
thereof by the registered Holder at the principal executive office of the
Company for a new Representatives' Warrant Certificate of like tenor and date
representing in the aggregate the right to purchase the same number of Warrant
Shares in such denominations as shall be designated by the Holder thereof at the
time of such surrender.

          Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Representatives' Warrant
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it and reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
the Representatives' Warrant, if mutilated, the Company will make and deliver a
new Warrant Certificate of like tenor, in lieu thereof.

          5.  Elimination of Fractional Interests.  The Company shall not be
              -----------------------------------                           
required to issue certificates representing fractions of shares of Common Stock
upon the exercise of the Representatives' Warrant, nor shall it be required to
issue scrip or pay cash in lieu of fractional interests, it being the intent of
the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of shares of Common Stock or other
securities, properties or rights.

          6.  Reservation and Listing of Securities.  The Company shall at all
              -------------------------------------                           
times reserve and keep available out of its authorized shares of Common Stock,
solely for the purpose of issuance upon the exercise of the Representatives'

Company. If, however, at any time prior to the expiration of the
Representatives' Warrants and their exercise, any of the following events shall
occur:

              (a) the Company shall take a record of the holders of its shares
of Common Stock for the purpose of entitling them to receive a dividend or
distribution payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings, as indicated by the
accounting treatment of such dividend or distribution on the books of the
Company; or

              (b) the Company shall offer to all the holders of its Common Stock
any additional shares of capital stock of the Company or securities convertible

subscription rights, or entitled to vote on such proposed dissolution,
liquidation, winding up or sale. Such notice shall specify such record date or
the date of closing the transfer books, as the case may be. Failure to give such
notice or any defect therein shall not affect the validity of any action taken
in connection with the declaration or payment of any such dividend, or the
issuance of any convertible or exchangeable securities, or subscription rights,
options or warrants, or any proposed dissolution, liquidation, winding up or
sale.

shall be substantially as set forth in Exhibit "A" to the Warrant Agreement
dated as of the date hereof by and among the Company, the Representative and
Continental Stock Transfer & Trust Company, as warrant agent (the "Redeemable

Representatives' Warrants shall evidence the right to initially purchase a fully
paid and non-assessable share of Common Stock at an initial purchase price of
$____ [150% of the initial public offering price per share of Common Stock] from
the Effective Date of the Registration Statement until 5:30 p.m. New York time
on ______ 2001 [5 years from the Effective Date of the Registration Statement]
at which time the Redeemable Warrants, unless the exercise period has been
extended, shall expire.  The exercise price of the Redeemable Warrants and the
number of shares of Common Stock issuable upon the exercise of the Redeemable
Warrants are subject to adjustment, whether or not the Representatives' Warrants
have been exercised and the Redeemable Warrants have been issued, in the manner
and upon the occurrence of the events set forth in Section 8 of the Redeemable
Warrant Agreement, which is hereby incorporated by reference and made a part
hereof as if set forth in its entirety herein.  Subject to the provisions of
this Agreement and upon issuance of the Redeemable Warrants underlying the
Representatives' Warrants, each registered holder of such Redeemable Warrant
shall have the right to purchase from the Company (and the Company shall issue
to such registered holders) up to the number of fully paid and non-assessable
shares of Common Stock (subject to adjustment as provided herein 

                                     -25-
<PAGE>
 
and in the Redeemable Warrant Agreement), free and clear of all preemptive
rights of stockholders, provided that such registered holder complies with the
terms governing exercise of the Redeemable Warrant set forth in the Redeemable
Warrant Agreement, and pays the applicable exercise price, determined in
accordance with the terms of the Redeemable Warrant Agreement. Upon exercise of
the Redeemable Warrants, the Company shall forthwith issue to the registered
holder of any such Redeemable Warrant in his name or in such name as may be
directed by him, certificates for the number of shares of Common Stock so
purchased. Except as otherwise provided in this Agreement, the Redeemable
Warrants underlying the Representatives' Warrants shall be governed in all
respects by the terms of the Redeemable Warrant Agreement. The Redeemable
Warrants shall be transferable in the manner provided in the Redeemable Warrant
Agreement, and upon any such transfer, a new Redeemable Warrant Certificate
shall be issued promptly to the transferee. The Company covenants to, and agrees
with, the Holder(s) that without the prior written consent of the Holder(s),
which will not be unreasonably withheld, the Redeemable Warrant Agreement will
not be modified, amended, canceled, altered or superseded, and that the Company
will send to each Holder, irrespective of whether or not the Representatives'
Warrants have been exercised, any and all notices required by the Redeemable
Warrant Agreement to be sent to holders of the Redeemable Warrants.

          1.   Form and Execution of Warrant Certificates.
               ------------------------------------------

               (a)  The Warrant Certificates shall be substantially in the form

herein) and may have such letters, numbers or other marks of identification or
designation and such legends, summaries or endorsements printed, lithographed or
engraved thereon as the Company may deem appropriate and as are not inconsistent

Certificates shall be delivered by the Warrant Agent to the Registered Holder
promptly and without further action by the Company, except as otherwise provided
by Section 4(a) hereof.

          1.   Exercise.
               --------

               (a)  Warrants in denominations of one or whole number multiples
thereof may be exercised by the Registered Holder 

                                       6
<PAGE>
 
thereof commencing at any time on or after the Initial Warrant Exercise Date,
but not after the Warrant Expiration Date, upon the terms and subject to the
conditions set forth herein and in the applicable Warrant Certificate. Warrants
may be exercised by their holders or redeemed by the Company as follows:
Exercise of Warrants shall be accomplished upon surrender of the Warrant
Certificate evidencing such Warrants, with the Form of Election to Purchase on
the reverse side thereof duly filled in and executed, to the Warrant Agent at
its business office, together with payment to the Warrant Agent of the Exercise
Price (as of the date of such surrender) of the Warrants then being exercised
and an amount equal to any applicable transfer tax and, if requested by the
Company, any other taxes or governmental charges which the Company may be
required by law to collect in respect of such exercise. Payment of the Exercise
Price and other amounts may be made by wire transfer of good funds, or by
certified or bank cashier's check, payable in lawful money of the United States
of America to the order of the Warrant Agent, who shall in turn make prompt
payment to the Company. No adjustment shall be made for any cash dividends,
whether paid or declared, on any securities issuable upon exercise of a Warrant.
A Warrant shall be deemed to have been exercised immediately prior to the close
of business on the Exercise Date and upon exercise thereof, the person entitled
to receive the securities deliverable upon such exercise shall be treated for
all purposes as the holder of the securities issued thereby as of the close of
business on the Exercise Date. If Warrants in denominations other than whole
number multiples thereof shall be exercised at one time by the same Registered
Holder, the number of full shares of Common Stock which shall be issuable upon
exercise thereof shall be computed on the basis of the aggregate number of full
shares of Common Stock issuable upon such exercise. As soon as practicable on or
after the Exercise Date and in any event within five business days after such
date, if one or more Warrants have been exercised in the manner described in
this subsection (a), the Warrant Agent on behalf of the Company shall cause to
be issued to the person or persons entitled to receive the same a Common Stock
certificate or certificates for the shares of Common Stock deliverable upon such
exercise, and the Warrant Agent shall deliver the same to the person or persons
entitled thereto. Upon the exercise of any one or more Warrants, the Warrant
Agent shall promptly notify the Company in writing of such fact and of the
number of securities delivered upon such exercise and, subject to subsection (b)
below, shall cause payment in cash or by check made payable to the order of the
Company, equal to the Exercise Price of such Warrants, to 

                                       7
<PAGE>
 
be deposited promptly in the Company's bank account or paid directly to the
Company, as specified by the Company.

               (a)  The Company shall engage the Representatives as Warrant
solicitation agents, and, at any time upon the valid exercise of any Warrants
after one year from the date hereof, excluding any Warrant (i) exercise at a
time when the Exercise Price exceeds the Market Price, (ii) held in a
discretionary account or (iii) exercised in an unsolicited transaction, the
Company shall instruct the Warrant Agent to, and the Warrant Agent shall, on a
daily basis, within two business days after such exercise, notify the
Representatives of the exercise of any such Warrants and shall, on a weekly
basis (subject to collection of funds constituting the tendered Exercise Price,
but in no event later than five business days after the last day of the calendar
week in which such funds were tendered), remit to the Representatives an amount
equal to five percent (5%) of the Exercise Price of such Warrants then being
exercised unless the Representatives shall have notified the Warrant Agent that
the payment of such amount with respect to such Warrant is violative of the
General Rules and Regulations promulgated under the Exchange Act, or the rules
and regulations of the Nasdaq or applicable state securities or "blue sky" laws,
or the Warrants are those underlying the Representatives' Warrants in which
event, the Warrant Agent shall have to pay such amount to the Company; provided,
that, the Warrant Agent shall not be obligated to pay any amounts pursuant to
this Section 4(b) during any week that such amounts payable are less than $1,000
and the Warrant Agent's obligation to make such payments shall be suspended
until the amount payable aggregates $1,000, and provided further, that, in any
event, any such payment (regardless of amount) shall be made not less frequently
than monthly. Notwithstanding the foregoing, the Representatives shall be
entitled to receive the commission contemplated by this Section 4(b) as Warrant
solicitation agent only if: (i) the Representatives have provided actual
services in connection with the solicitation of the exercise of a Warrant by a
Registered Holder and (ii) the Registered Holder exercising a Warrant
affirmatively designates in writing on the exercise form on the reverse side of
the Warrant Certificate that the exercise of such Registered Holder's Warrant
was solicited by the Representatives.

               (a)  The Company shall not be required to issue fractional shares
on the exercise of Warrants. Warrants may only be exercised in such multiples as
are required to permit the issuance by the Company of one or more whole shares.
If one or 

                                       8
<PAGE>
 
more Warrants shall be presented for exercise in full at the same time by the
same Registered Holder, the number of whole shares which shall be issuable upon
such exercise thereof shall be computed on the basis of the aggregate number of
shares purchasable on exercise of the Warrants presented. If any fraction of a
share would, except for the provisions provided herein, be issuable on the
exercise of any Warrant (or specified portion thereof), the Company shall pay an
amount in cash equal to such fraction multiplied by the then current Market
Price of a share of Common Stock, determined as follows:

               (1)  If the Common Stock is listed, or admitted to unlisted
trading privileges on a national securities exchange, or is traded on Nasdaq,
the current market value of a share of Common Stock shall be the closing sale
price of the Common Stock at the end of the regular trading session on the last
business day prior to the date of exercise of the Warrants on whichever of such
exchanges or Nasdaq which had the highest average daily trading volume for the
Common Stock on such day; or

               (1)  If the Common Stock is not listed or admitted to unlisted
trading privileges on any national securities exchange, or listed, quoted or
reported for trading on Nasdaq, but is traded in the over-the-counter market,
the current market value of a share of Common Stock shall be the average of the
last reported bid and asked prices of the Common Stock reported by the National
Quotation Bureau, Inc. on the last business day prior to the date of exercise of
the Warrants; or

               (1)  If the Common Stock is not listed, admitted to unlisted
trading privileges on any national securities exchange, or listed, quoted or
reported for trading on Nasdaq, and bid and asked prices of the Common Stock are
not reported by the National Quotation Bureau, Inc., the current market value of
a share of Common Stock shall be an amount, not less than the book value thereof
as of the end of the most recently completed fiscal quarter of the Company
ending prior to the date of exercise, determined by the members of the Board of
Directors of the Company exercising good faith and using customary valuation
methods.

          1.   Reservation of Shares; Listing; Payment of Taxes; etc.
               ------------------------------------------------------

               (a)  The Company covenants that it will at all times reserve and
keep available out of its authorized Common Stock, solely for the purpose of
issue upon exercise of Warrants, such number of shares of Common Stock as shall
then be issuable 

                                       9
<PAGE>
 
upon the exercise of all outstanding Warrants. The Company covenants that all
shares of Common Stock which shall be issuable upon exercise of the Warrants
shall, at the time of delivery thereof, be duly and validly issued and fully
paid and nonassessable and free from all preemptive or similar rights, taxes,
liens and charges with respect to the issue thereof, and that upon issuance such
shares shall be listed on each securities exchange, if any, on which the other
shares of outstanding Common Stock of the Company are then listed.

               (a)  The Company covenants that if any securities to be reserved
for the purpose of exercise of Warrants hereunder require registration with, or
approval of, any governmental authority under any federal securities law before
such securities may be validly issued or delivered upon such exercise, then the
Company will file a registration statement under the federal securities laws or
a post-effective amendment, use its best efforts to cause the same to become
effective and to keep such registration statement current on or after the
Initial Warrant Exercise Date and while any of the Warrants are outstanding and
deliver a prospectus which complies with Section 10(a)(3) of the Act, to the
Registered Holder exercising the Warrant (except, if in the opinion of counsel
to the Company, such registration is not required under the federal securities
law or if the Company receives a letter from the staff of the Commission stating
that it would not take any enforcement action if such registration is not
effected; provided, however, that (i) if at the time of exercise of any Warrants
          --------  -------
the Company does not have in place an effective registration statement or is
otherwise, in the good faith determination of the Board of Directors of the
Company, precluded by applicable laws from issuing the underlying shares of
Common Stock, the Company may, in lieu of issuance of the shares of Common
Stock, elect to redeem the Warrants duly surrendered for exercise for a price
per Warrant equal to the difference between the Market Price of the securities
for which such Warrant is exercisable on the date of such submission and the
Exercise Price of such Warrants, and in the event of such redemption, the
Company will pay to the holder of such Warrants the above described redemption
price in cash within 10 business days after receipt of notice from the Warrant
Agent that such Warrants have been submitted for exercise, and (ii) if the
Market Price of the Common Stock is less than the Exercise Price, then the
Company need not take such actions to file a registration statement (or a
post effective amendment to a registration statement) with respect to the
issuance of Common Stock upon exercise of the Warrants until such time as the
Company has been subject to the requirements of Section 12 or 15(d) of the
Securities Exchange Act of 1934, as amended, for a period of at least twelve
calendar months immediately preceding the filing of the registration statement).
The Company will use its best efforts to obtain appropriate approvals or
registrations under state "blue sky" securities laws with respect to any such
securities. However, Warrants may not be exercised by,

                                      10
<PAGE>
 
or shares of Common Stock issued to, any Registered Holder in any state in which
such exercise would be unlawful.

               (a)  The Company shall pay all documentary, stamp or similar
taxes and other governmental charges that may be imposed with respect to the
issuance of Warrants, or the issuance or delivery of any shares of Common Stock
upon exercise of the Warrants; provided, however, that if shares of Common Stock
                               --------  -------
are to be delivered in a name other than the name of the Registered Holder of
the Warrant Certificate representing any Warrant being exercised, then no such
delivery shall be made unless the person requesting the same has paid to the
Warrant Agent the amount of transfer taxes or charges incident thereto, if any;
provided, however, that the Company shall not be required (i) to pay any tax
which may be payable in respect of any transfer involved in the transfer and
delivery of Warrant Certificates or (ii) to issue or deliver any certificate for
shares of Common Stock or other securities upon the exercise of any Warrant
Certificate until any such tax shall have been paid, all such tax being payable
by the holder of such Warrant Certificate at the time of surrender.

               (a)  The Warrant Agent is hereby irrevocably authorized as the
Transfer Agent to requisition from time to time certificates representing shares
of Common Stock or other securities required to be issued upon exercise of the
Warrants, and the Company will comply with all such requisitions.

          1.   Exchange and Registration of Transfer.
               ------------------------------------- 

               (a)  Warrant Certificates may be exchanged for other Warrant
Certificates representing an equal aggregate number of Warrants of the same
class or may be transferred in whole or in part. Warrant Certificates to be
exchanged shall be surrendered to the Warrant Agent at its Corporate Office,
and, promptly following satisfaction of the terms and provisions hereof, the
Company shall execute and the Warrant Agent shall countersign, issue and deliver
in exchange therefor the Warrant Certificate or Certificates which the
Registered Holder making the exchange shall be entitled to receive.

               (a)  The Warrant Agent shall keep, at its office, books in which,
subject to such reasonable regulations as it may prescribe, it shall register
Warrant Certificates and the transfer thereof in accordance with customary
practice. Upon due presentment for registration of transfer of any Warrant
Certificate at such office, the Company shall execute and the Warrant Agent
shall issue and deliver to the transferee or 

                                      11
<PAGE>
 
transferees a new Warrant Certificate or Certificates representing an equal
aggregate number of Warrants of the same class.

               (a)  With respect to all Warrant Certificates presented for
registration of transfer, or for exchange or exercise, the subscription or
exercise form, as the case may be, on the reverse thereof shall be duly endorsed
or be accompanied by a written instrument or instruments of transfer and
subscription, in form satisfactory to the Company and the Warrant Agent, duly
executed by the Registered Holder thereof or his attorney-in-fact duly
authorized in writing.

               (a)  A service charge may be imposed on the Registered Holder by
the Warrant Agent for any exchange or registration of transfer of Warrant
Certificates. In addition, the Company may require payment by such holder of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith.

               (a)  All Warrant Certificates surrendered for exercise or for
exchange in case of mutilated Warrant Certificates shall be promptly canceled by
the Warrant Agent and thereafter retained by the Warrant Agent until termination
of this Agreement.

               (a)  Prior to due presentment for registration of transfer
thereof, the Company and the Warrant Agent may deem and treat the Registered
Holder of any Warrant Certificate as the absolute owner thereof and of each
Warrant represented thereby (notwithstanding any notations of ownership or
writing thereon made by anyone other than a duly authorized officer of the
Company or the Warrant Agent) for all purposes and shall not be affected by any
notice to the contrary.

          1.   Loss or Mutilation.  Upon receipt by the Company and the Warrant
               ------------------
Agent of evidence satisfactory to them of the ownership of and the loss, theft,
destruction or mutilation of any Warrant Certificate and (in the case of loss,
theft or destruction) of indemnity satisfactory to them, and (in case of
mutilation) upon surrender and cancellation thereof, the Company shall execute
and the Warrant Agent shall (in the absence of notice to the Company and/or the
Warrant Agent that a new Warrant Certificate has been acquired by a bona fide
purchaser) countersign and deliver to the Registered Holder in lieu thereof a
new Warrant Certificate of like tenor representing an equal aggregate number of
Warrants. Applicants for a substitute Warrant Certificate shall also comply with
such other reasonable regulations and pay such other reasonable charges as the
Warrant Agent may prescribe.

                                      12

          1.  Adjustments of Number and Kind of Shares Purchasable and Exercise
              -----------------------------------------------------------------
Price. The number and kind of securities or other property purchasable upon
- -----
exercise of a Warrant shall be subject to adjustment from time to time upon the
occurrence, after the date hereof, of any of the following events:

               (a)  Dividends, Stock Splits, Reverse Splits, Etc. In case the
                    --------------------------------------------
Company shall (i) pay a dividend in, or make a distribution of, shares of Common
Stock or of capital stock convertible into Common Stock on its outstanding
Common Stock, (ii) subdivide its outstanding shares of Common Stock into a
greater number of such shares or (iii) combine its outstanding shares of Common
Stock into a smaller number of such shares, the total number of shares of Common
Stock purchasable upon the exercise of each Warrant outstanding immediately
prior thereto shall be adjusted so that the Registered Holder of any Warrant
Certificate thereafter surrendered for exercise shall be entitled to receive, at
the same aggregate Exercise Price, the number of shares of Common Stock which
such holder would have owned or have been entitled to receive immediately
following the happening of any of the events described above had such Warrant
been exercised in full immediately prior to the happening of such event. Any
adjustment made pursuant to this subsection shall, in the case of a stock
dividend or distribution, become effective as of the record date therefor and,
in the case of a subdivision or combination, be made as of the effective date
thereof. If, as a result of an adjustment made pursuant to this subsection, the
Registered Holder of any Warrant Certificate thereafter surrendered for exercise
shall become entitled to receive shares of two or more classes of capital stock
of the Company, the Board of Directors of the Company (whose determination shall
be conclusive and shall be evidenced by a Board resolution filed with the
Warrant Agent) shall determine the allocation of the adjusted Exercise Price
between or among shares of such classes of capital stock.

               (a)  No Change in Aggregate Exercise Price. In the event of any
                    ------------------------------------- 
adjustment of the total number of shares of Common Stock purchasable upon the
exercise of Warrants pursuant to subsection (a) above, the aggregate Exercise
Price of each such Warrant shall remain unchanged, but the number of shares of
capital stock obtainable on exercise of each such Warrant shall be adjusted as
provided in subsection (a) above.

               (a)  Reorganization or Reclassification. In the event of a
                    ----------------------------------
capital reorganization or a reclassification of the Common Stock (except as
provided in subsection (a) above or subsection (e) below), any Registered Holder
of a Warrant, upon exercise of such Warrant, shall be entitled to receive, in
substitution for the Common Stock to which he would have become entitled upon
exercise immediately prior to such reorganization or reclassification, the
shares (of any class or classes) or other securities or property of the Company
(or cash) that he would have been entitled to receive at the same aggregate
Exercise Price upon such reorganization or reclassification if such Warrant had
been exercised immediately prior thereto; and in any such case, appropriate
provision (as determined by the Board of Directors of the Company, whose
determination shall be conclusive and

                                      13
<PAGE>
 
shall be evidenced by a certified Board resolution filed with the Warrant Agent)
shall be made for the application of this Section 8 with respect to the rights
and interests thereafter of the Registered Holders of all then outstanding
Warrants (including but not limited to the allocation of the Exercise Price
between or among shares of classes of capital stock), to the end that this
Section 8 (including the adjustments of the number of shares of Common Stock or
other securities purchasable and the Exercise Price thereof) shall thereafter be
reflected, as nearly as reasonably practicable, in all subsequent exercises of
the Warrants for any shares or securities or other property (or cash) thereafter
deliverable upon the exercise of the Warrants.

               (a)  Certificate of Adjustment. Whenever the number of shares of
                    -------------------------
Common Stock or other securities purchasable upon exercise of a Warrant is
adjusted as provided in this Section 8, the Company will promptly file with the
Warrant Agent a certificate signed by a Chairman or Co-Chairman of the Board or
the President or a Vice President of the Company and by the Chief Financial
Officer, Treasurer or an Assistant Treasurer or the Secretary or an Assistant
Secretary of the Company setting forth the number and kind of securities or
other property purchasable upon exercise of a Warrant, as so adjusted, stating
that such adjustments in the number or kind of shares or other securities or
property conform to the requirements of this Section 8, and setting forth a
brief statement of the facts accounting for such adjustments. Promptly after
receipt of such certificate, the Company, or the Warrant Agent at the Company's
request, will deliver, by first class, postage prepaid mail, a brief summary
thereof (to be supplied by the Company) to the registered holder's of the
outstanding Warrant Certificates; provided, however, that failure to file or to
                                  --------  -------
give any notice required under this subsection, or any defect therein, shall not
affect the legality or validity of any such adjustments under this Section 8;
and provided, further, that, where appropriate, such notice may be given in
    --------  -------
advance and included as part of the notice required to be given pursuant to
Section 12 hereof.

               (a)  Merger or Consolidation. In case of any consolidation of the
                    -----------------------
Company with, or merger of the Company into, another corporation (other than a
consolidation or merger which does not result in any reclassification or change
of the outstanding Common Stock), or in case of any sale or conveyance to
another corporation of the property of the Company as an entirety or
substantially as an entirety, the corporation formed by such consolidation or
merger or the corporation which shall have acquired such assets, as the case may
be, shall execute and deliver to the Warrant Agent a supplemental warrant
agreement provided that the Registered Holder of each Warrant then outstanding
shall have the right thereafter (until the expiration of such Warrant) to
receive, upon exercise of such Warrant, solely the kind and amount of shams of
stock and other securities and property (or cash) receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Common Stock of the Company for which such Warrant might have been exercised
immediately prior to such consolidation, merger, sale or transfer. Such
supplemental warrant agreement shall provide for adjustments which shall be as
nearly equivalent as may be 

                                      14
<PAGE>
 
practicable to the adjustments provided in this Section. The above provision of
this Subsection shall similarly apply to successive consolidations, mergers,
sales or transfers.

               (a)  Effect of Adjustments on Warrant Certificates. Irrespective
                    ---------------------------------------------
of any adjustments in the number of kind of shares issuable upon exercise of
Warrants, Warrant Certificates theretofore or thereafter issued may continue to
express the same price and number and kind of shares as are stated in the
similar Warrant Certificates initially issuable pursuant to this Warrant
Agreement.

               (a)  Assistance of Accounting Firm in Making Computations. The
                    ---------------------------------------------------- 
Company may retain a firm of independent public accountants of recognized
standing, which may be the firm regularly retained by the Company, selected by
the Board of Directors of the Company or the Executive Committee of said Board,
and not disapproved by the Warrant Agent, to make any computation required under
this Section, and a certificate signed by such firm shall, in the absence of
fraud or gross negligence, be conclusive evidence of the correctness of any
computation made under this Section.

               (a)  "Common Stock". For the purpose of this Section, the term
                    -------------- 
"Common Stock" shall mean (i) the class of stock designated as Common Stock in
the Certificate of Incorporation of the Company, as amended, at the date of this
Agreement, or (ii) any other class of stock resulting from successive changes or
reclassifications of such Common Stock consisting solely of changes in par
value, or from par value to no par value, or from no par value. In the event
that at any time as a result of an adjustment made pursuant to this Section, the
Registered Holder of any Warrant thereafter surrendered for exercise shall
become entitled to receive any shares of capital stock of the Company other than
shares of Common Stock, thereafter the number of such other shares so receivable
upon exercise of any Warrant shall be subject to adjustment from time to time in
a manner and on terms as nearly equivalent as practicable to the provisions with
respect to the Common Stock contained in this Section, and all other provisions
of this Agreement, with respect to the Common Stock, shall apply on like terms
to any such other shares.

          1.   Redemption.
               ----------

               (a)  Commencing on the Initial Warrant Redemption Date, the
Company may, on 30 days' prior written notice, redeem all, but not less than
all, the Warrants at five cents ($0.05) per Warrant, provided, however, that
                                                     --------  -------
before any such call for redemption of Warrants can take place, the average
closing sale price for the Common Stock as reported by Nasdaq, if the Common
Stock is then traded on the Small Cap Market (or the average closing sale price,
if the Common Stock is then traded on the Nasdaq National Market or on a
national securities exchange) shall have equalled or exceeded $_____ per share
200% of the initial public offering price 

                                      15
<PAGE>
 
per share of Common Stock for any twenty (20) consecutive trading days ending on
the day prior to the date on which the notice contemplated by (b) and (c) below
is given (subject to adjustment in the event of any stock splits or other
similar events as provided in Section 8 hereof).

               (a)  In case the Company shall exercise its right to redeem all
of the Warrants, it shall give or cause to be given notice to the Registered
Holders of the Warrants, by mailing to such Registered Holders a notice of
redemption, first class, postage prepaid, at their last address as shall appear
on the records of the Warrant Agent. Any notice mailed in the manner provide
herein shall be conclusively presumed to have been duly given whether or not the
Registered Holder receives such notice. Not less than five (5) business days
prior to the mailing to the Registered Holders of the Warrants of the notice of
redemption, the Company shall deliver or cause to be delivered to the
Representatives a similar notice telephonically and confirmed in writing, and if
the Representatives are engaged as Warrant solicitation agents, the Company
shall also cause to be delivered to the Representatives a list of the Registered
Holders (including their respective addresses and number of Warrants
beneficially owned) to whom such notice of redemption has been or will be given.

               (a)  The notice of redemption shall specify (i) the redemption
price, (ii) the Redemption Date, which shall in no event be less than thirty
(30) days after the date of mailing of such notice, (iii) the place where the
Warrant Certificate shall be delivered and the redemption price shall be paid,
(iv) that the Representatives shall receive the commission contemplated by
Section 4(b) hereof, and (v) that the right to exercise the Warrant shall
terminate at 5:00 p.m. (New York time) on the business day immediately preceding
the date fixed for redemption. No failure to mail such notice nor any defect
therein or in the mailing thereof shall affect the validity of the proceedings
for such redemption except as to a holder (a) to whom notice was not mailed or
(b) whose notice was defective. An affidavit of the Warrant Agent or the
Secretary or Assistant Secretary of the Company that notice of redemption has
been mailed shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

               (a)  Any right to exercise a Warrant shall terminate at 5:00 p.m.
(New York time) on the business day immediately preceding the Redemption Date.
The redemption price payable to the Registered Holders shall be mailed to such
persons at their addresses of record.

                                      16
<PAGE>
 
               (a)  If the Representatives act as the Warrant solicitation
agents for the Company, the Company shall indemnify the Representatives and each
person, if any, who controls the Representatives within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act against all loss, claim,
damage, expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from the registration statement or prospectus referred to in Section 5(b) hereof
to the same extent and with the same effect (including the provisions regarding
contribution) as the provisions pursuant to which the Company has agreed to
indemnify the Representatives contained in Section 7 of the Underwriting
Agreement.

               (a)  Five business days prior to the Redemption Date, the Company
shall furnish to the Representatives, as Warrant solicitation agents, (i) an
opinion of counsel to the Company, dated such date and addressed to the
Representatives, and (ii) a "cold comfort" letter dated such date addressed to
each of the Representatives, signed by the independent public accountants who
have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities.

               (a)  On and after the date fixed for redemption, the Registered
Holders shall have no rights with respect to the Warrants except to receive the
$.05 per Warrant upon surrender of their Warrant Certificates.

          1.   Concerning the Warrant Agent.
               ----------------------------

               (a)  The Warrant Agent acts hereunder as agent and in a
ministerial capacity for the Company and the Representatives, and its duties
shall be determined solely by the provisions hereof. The Warrant Agent shall
not, by issuing and delivering Warrant Certificates or by any other act
hereunder, be deemed to make any representations as to the validity or value or
authorization of the Warrant Certificates (except its 

                                      17
<PAGE>
 
countersignature thereof) or the Warrants represented thereby or of any
securities or other property delivered upon exercise of any Warrant or whether
any stock issued upon exercise of any Warrant is fully paid and nonassessable.

               (a)  The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of Warrant Certificates to make or cause to be made
any adjustment of the Exercise Price or the Redemption Price provided in this
Agreement, or to determine whether any fact exists which may require any such
adjustments, or with respect to the nature or extent of any such adjustments,
when made, or with respect to the method employed in making the same (except
with respect to the exercise of Warrant Certificates after actual notice of any
adjustment of the Exercise Price). It shall not (i) be liable for any recital or
statement of fact contained herein or for any action taken, suffered or omitted
by it in reliance on any Warrant Certificate or other document or instrument
believed by it in good faith to be genuine and to have been signed or presented
by the proper party or parties (except its countersignature on the Warrant
Certificates and such statements or recitals as describe the Warrant Agent or
action taken or to be taken by it), (ii) be responsible for any failure on the
part of the Company to comply with any of its covenants and obligations
contained in this Agreement or in any Warrant Certificate, or (iii) be liable
for any act or omission in connection with this Agreement except for its own
negligence, bad faith or willful misconduct.

               (a)  The Warrant Agent may at any time consult with counsel
satisfactory to it (who may be counsel for the Company or for the
Representatives) and shall incur no liability or responsibility for any action
taken, suffered or omitted by it in good faith in accordance with the opinion or
advice of such counsel.

               (a)  Any notice, statement, instruction, request, direction,
order or demand of the Company shall be sufficiently evidenced by an instrument
signed by the Chairman of the Board of Directors, Chief Executive Officer, Chief
Financial Officer, President or any Vice President (unless other evidence in
respect thereof is herein specifically prescribed). The Warrant Agent shall not
be liable for any action taken, suffered or omitted by it in accordance with
such notice, statement, instruction, request, direction, order or demand
reasonably believed by it to be genuine.

                                      18
<PAGE>
 
               (a)  The Company agrees to pay the Warrant Agent reasonable
compensation for its services hereunder and to reimburse it for its reasonable
expenses hereunder; the Company further agrees to indemnify the Warrant Agent
and save it harmless from and against any and all losses, expenses and
liabilities, including judgments, costs and counsel fees, for anything done or
omitted by the Warrant Agent in the execution of its duties and powers hereunder
except losses, expenses and liabilities arising as a result of the Warrant
- ------
Agent's negligence, bad faith or willful conduct.

               (a)  The Warrant Agent may resign its duties and be discharged
from all further duties and liabilities hereunder (except liabilities resulting
as a result of the Warrant Agent's own gross negligence or willful misconduct),
after giving 30 days' prior written notice to the Company. At least 15 days
prior to the date such resignation is to become effective, the Warrant Agent
shall cause a copy of such notice of resignation to be mailed to the Registered
Holder of each Warrant Certificate at the Company's expense. Upon such
resignation, or any inability of the Warrant Agent to act as such hereunder, the
Company shall appoint in writing a new warrant agent. If the Company shall fail
to make such appointment within a period of 15 days after it has been notified
in writing of such resignation by the resigning Warrant Agent, then the
Registered Holder of any Warrant Certificate may apply to any court of competent
jurisdiction for the appointment of a new warrant agent. Any new warrant agent,
whether appointed by the Company or by such a court, shall be a bank or trust
company having a capital and surplus, as shown by its last published report to
its stockholders, of not less than $10,000,000 or a stock transfer company.
After acceptance in writing of such appointment by the new warrant agent is
received by the Company, such new warrant agent shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally named
herein as the Warrant Agent, without any further assurance, conveyance, act or
deed; but if for any reason it shall be necessary or expedient to execute and
deliver any further assurance, conveyance, act or deed, the same shall be done
at the expense of the Company and shall be legally and validly executed and
delivered by the resigning Warrant Agent. Not later than the effective date of
any such appointment the Company shall file notice thereof with the resigning
Warrant Agent and shall forthwith cause a copy of such notice to be mailed to
the Registered Holder of each Warrant Certificate.

     Any corporation into which the Warrant Agent or any new warrant agent may
be converted or merged, any 

                                      19
<PAGE>
 
corporation resulting from any consolidation to which the Warrant Agent or any
new warrant agent shall be a party, or any corporation succeeding to the
corporate trust business of the Warrant Agent or any new warrant agent shall be
a successor warrant agent under this Agreement without any further act, provided
that such corporation is eligible for appointment as successor to the Warrant
Agent under the provisions of the preceding paragraph. Any such successor
warrant agent shall promptly cause notice of its succession as warrant agent to
be mailed to the Company and to the Registered Holders of each Warrant
Certificate.

               (a)  The Warrant Agent, its subsidiaries and affiliates, and any
of its or their officers or directors, may buy and hold or sell Warrants or
other securities of the Company and otherwise deal with the Company in the same
manner and to the same extent and with like effect as though it were not Warrant
Agent. Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

               (a)  The Warrant Agent shall retain for a period of two years
from the date of exercise any Warrant Certificate received by it upon such
exercise.

               (a)  The Warrant Agent shall account promptly to the Company with
respect to Warrants exercised and concurrently pay to the Company all moneys
received by the Warrant Agent for the purchase of securities or other property
through the exercise of such Warrants.

          1.   Modification of Agreement.
               -------------------------

          The Warrant Agent and the Company may by supplemental agreement make
any changes or corrections in this Agreement (i) that they shall deem
appropriate to cure any ambiguity or to correct any defective or inconsistent
provision or manifest mistake or error herein contained; or (ii) that they may
deem necessary or desirable and which shall not adversely affect the interests
of the holders of Warrant Certificates; provided, however, that this Agreement
                                        --------  -------
shall not otherwise be modified, supplemented or altered in any respect except
with the consent in writing of the Registered Holders representing not less than
66-2/3% of the Warrants then outstanding; provided, further, that no change in
                                          --------  -------
the number or nature of the securities purchasable upon the exercise of any
Warrant, or to increase the Exercise Price therefor or to accelerate of the
Warrant Expiration Date, shall be made without the consent in writing of the
Registered Holder of the Warrant Certificate representing such Warrant, other
than such changes as are presenting specifically prescribed by this Agreement as
originally executed. In addition, this Agreement may not be modified, amended or
supplemented without the prior written consent of both 

                                      20
<PAGE>
 
of the Representatives, other than to cure any ambiguity or to correct any
provision which is inconsistent with any other provision of this Agreement or to
make any such change that is necessary or desirable and which shall not
adversely affect the interests of the Representatives and except as may be
required by law.

          1.   Notices.
               -------

          All notices, requests, consents and other communications hereunder

          This Agreement shall be governed by and construed in accordance with
the laws of the state of California without giving effect to conflicts of laws.

          1.   Binding Effect.
               --------------

          This Agreement shall be binding upon and inure to the benefit of the
Company, the Representatives, the Warrant Agent and their respective successors
and assigns and the Registered Holders from time to time of Warrant Certificates

confer upon any other person any right, remedy or claim, in equity or at law, or
to impose upon any other person any duty, liability or obligation.

               This Agreement shall terminate at the close of business on the
Expiration Date of all of the Warrants or such earlier date upon which all
Warrants have been exercised or redeemed, except that the Warrant Agent shall
account to the Company for all Warrants outstanding and all cash held by it and
the provisions of Section 10 hereof shall survive such termination.

          1.   Counterparts.
               ------------

          This Agreement may be executed in several counterparts, which taken
together shall constitute a single document.

                                      21
<PAGE>
 
          1.   Holders of Warrants Not Deemed Shareholders. No holder of a
               -------------------------------------------
Warrant, as such, shall be entitled to vote, receive dividends or be deemed the
holder of Common Stock or any other securities of the Company which may at any
time be issuable on the exercise of the Warrants represented thereby for any
purpose whatever, nor shall anything contained herein or in any Warrant
Certificate be construed to confer upon any holder of a Warrant, as such, any of
the rights of a shareholder of the Company or any right to vote for the election
of directors or upon any matter submitted to shareholders at any meeting
thereof, or to give or withhold consent to any corporate action (whether upon
any recapitalization, issuance of stock, reclassification of stock, change of
par value or change of stock to no par value, consolidation, merger, conveyance
or otherwise), or to receive notice of meetings or other actions affecting
shareholders, or to receive dividend or subscription rights, or otherwise, until
such Warrant Certificate shall have been exercised in accordance with the
provisions hereof and the receipt of the Exercise Price and any other amounts
payable upon such exercise by the Warrant Agent.

          1.   Benefits of this Agreement. Nothing in this Agreement or in the
               --------------------------
Warrant Certificates shall be construed to give to any person or corporation
other than the Company, the Representatives, the Warrant Agent, and their
respective successors and assigns hereunder and the Registered Holders of the
Warrant Certificates any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the
Company, the Representatives, the Warrant Agent, their respective successors and
assigns hereunder and the Registered Holders of the Warrant Certificates.

of Redeemable Warrants (the "Warrants") specified above. Each Warrant initially
entitles the Registered Holder to purchase, subject to the terms and conditions
set forth in this Certificate and the Warrant Agreement (as hereinafter
defined), one fully paid and nonassessable share of Common Stock, par value
$____ per share, of Isonics Corporation, a California corporation (the
"Company"), at any time between the date of the Prospectus (the "Initial Warrant
Exercise Date"), and the earlier to occur of the Expiration Date (as hereinafter
defined ) and the Redemption Date (as hereinafter defined) upon the presentation
and surrender of this Warrant Certificate with the Subscription Form on the
reverse hereof duly executed, at the corporate office of American Stock Transfer
& Trust Company, as Warrant Agent, or its successor (the "Warrant Agent"),
accompanied by payment of $_____ per share, subject to adjustment (the "Exercise
Price"), in lawful money of the United States of America in cash or by check
made payable to the Warrant Agent for the account of the Company.

          This Warrant Certificate and each Warrant represented hereby are
issued pursuant to and are subject in all respects to the terms and conditions
set forth in the Warrant Agreement (the "Warrant Agreement"), dated ____________
__, 1996, by and between the Company, Pryor, McClendon, Counts & Co., Inc.

          In the event of certain contingencies provided for in the Warrant
Agreement, the Exercise Price and the number of shares of Common Stock subject
to purchase upon the exercise of each Warrant represented hereby are subject to
modification or adjustment.

          Each Warrant represented hereby is exercisable at the option of the
Registered Holder, but no fractional interests will be issued. In the case of
the exercise of less than all the Warrants represented hereby, the Company shall
cancel this Warrant Certificate upon the surrender hereof and shall execute and
deliver a new Warrant Certificate or Warrant Certificates of like tenor, which
the Warrant Agent shall countersign, for the balance of such Warrants.

          The term "Expiration Date" shall mean 5:00 p.m. (New York time) on the
date which is five (5) years after the Initial Warrant Exercise Date or the date
fixed for redemption hereof, whichever date is earlier. If each such date shall
in the State of New York be a holiday or a day on which the banks are authorized
to close, then the Expiration Date shall mean 5:00 p.m. (New York time) the next
following day which in the State of New York is not a holiday or a day on which
banks are authorized to close.

          The Company shall not be obligated to deliver any securities pursuant
to the exercise of this Warrant unless a registration statement under the
Securities Act of 1933, as amended (the "Act'), with respect to such securities
is effective or an exemption thereunder is available. The Company has covenanted
and agreed that it will file a registration statement under the Federal
securities laws, use its best efforts to cause the same to become effective, use
its best efforts to keep such registration statement current, if required under
the Act, while any of the Warrants are outstanding, and deliver a prospectus
which complies with Section 10(a)(3) of the Act to the Registered Holder
exercising this Warrant; provided, however, that (i) if at the time of exercise
                         --------  -------
of any of the Warrants the Company does not have in place an effective
registration statement or is otherwise, in the good faith determination of the
Board of Directors of the Company, precluded by applicable laws from issuing the
shares of Common Stock issuable upon such exercise, the Company may, in lieu of
issuance of those shares, elect to redeem the Warrants duly surrendered for
exercise for a price per Warrant equal to the difference between the Market
Price (as defined below) of a share of the Common Stock on the date of such
submission and the Exercise Price, and in the event of such redemption, the
Company will pay to the Registered Holder the above-described redemption price
in cash within 10 business days after receipt of notice from the Warrant Agent
that such Warrants have been submitted for exercise, and (ii) if the Market
Price of the Common Stock is less than the Exercise Price, then the Company need
not take such actions to file a registration statement (or a post-effective
amendment to a registration statement) with respect to the issuance of Common
Stock upon exercise of the Warrants until such time as the Company has been
subject to the requirements of Section 12 or 15(d) of the Securities Exchange
Act of 1934, as amended, for a period of at least 

                                       2
<PAGE>
 
twelve calendar months immediately preceding the filing of the registration
statement. This Warrant shall not be exercisable by a Registered Holder in any
state where such exercise would be unlawful.

          The term "Market Price" shall mean the last reported sale price, or,
in case no such reported sale takes place on such day, the average of the last
reported sales prices for the last three (3) trading days, in either case as
officially reported by the principal securities exchange on which the Common
Stock is listed or admitted to trading or by the Nasdaq SmallCap Market, or, if
the Common Stock is not listed or admitted to trading on any national securities
exchange or quoted by the Nasdaq, the average closing bid price as furnished by
the Nasdaq through Nasdaq or similar organization if Nasdaq is no longer
reporting such information, or if the Common Stock is not quoted on Nasdaq, as
determined in good faith (using customary valuation methods) by resolution of
the members of the Board of Directors of the Company, based on the best
information available to it.

          This Warrant Certificate is exchangeable, upon the surrender hereof by
the Registered Holder at the corporate office of the Warrant Agent, for a new
Warrant Certificate or Warrant Certificates of like tenor representing an equal
aggregate number of Warrants, each of such new Warrant Certificates to represent
such number of Warrants as shall be designated by such Registered Holder at the
time of such surrender. Upon due presentment and payment of any tax or other
charge imposed in connection therewith or incident thereto, for registration of
transfer of this Warrant Certificate at such office, a new Warrant Certificate
or Warrant Certificates representing an equal aggregate number of Warrants will
be issued to the transferee in exchange therefor, subject to the limitations
provided in the Warrant Agreement.

          Prior to the exercise of any Warrant represented hereby, the
Registered Holder shall not be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

          Subject to the provisions of the Warrant Agreement, this Warrant may
be redeemed at the option of the Company, at a redemption price of $0.05 per
Warrant, at any time commencing after _______________ [the date 12 months from
the date of the Prospectus], provided that the average closing sale price for
the Common Stock as reported by the Nasdaq Small Cap Market, if the Common Stock
is then traded on the Nasdaq SmallCap Market (or the average closing sale price,
if the Common Stock is then traded on the Nasdaq National Market or a national
securities exchange), shall have equalled or exceeded $_____ per share for any
twenty (20) consecutive trading days ending on the fifth trading day prior to
the date on which the Notice of Redemption, as defined below, is given (subject
to adjustment in the event of any stock splits or other similar events). Notice
of redemption (the "Notice of Redemption") shall be given not later than the
thirtieth day before the date fixed for redemption, or as 

                                       3
<PAGE>
 
provided in the Warrant Agreement. On and after the date fixed for redemption,
the Registered Holder shall have no rights with respect to the Warrants except
to receive the $0.05 per Warrant upon surrender of this Warrant Certificate.

          Upon certain circumstances, the Representatives may be entitled to
receive an aggregate of five percent (5%) of the Exercise Price of the Warrants
represented hereby, if it is engaged as a Warrant solicitation agent by the
Company.

          Prior to due presentment for registration of transfer hereof, the
Company and the Warrant Agent may deem and treat the Registered Holder as the
absolute owner hereof and of each Warrant represented hereby (notwithstanding
any notations of ownership or writing hereon made by anyone other than a duly
authorized officer of the Company or the Warrant Agent) for all purposes and
shall not be affected by any notice to the contrary, except as provided in the
Warrant Agreement.

          This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of Delaware without giving effect to
conflicts of laws.

          This Warrant Certificate is not valid unless countersigned by the
Warrant Agent.

THIS CERTIFIES THAT, FOR VALUE RECEIVED

or its registered assigns (the "Registered Holder") is the owner of the number
of Redeemable Warrants (the "Warrants") specified above.  Each Warrant initially
entitles the Registered Holder to purchase, subject to the terms and conditions
set forth in this Certificate and the Warrant Agreement (as hereinafter
defined), one fully paid and nonassessable share of Common Stock, par value
$____ per share, of Isonics Corporation, a California corporation (the
"Company"), at any time between the date of the Prospectus (the "Initial Warrant
Exercise Date"), and the earlier to occur of the Expiration Date (as hereinafter
defined) and the Redemption Date (as hereinafter defined) upon the presentation
and surrender of this Warrant Certificate with the Subscription Form on the
reverse hereof duly executed, at the corporate office of Continental Stock
Transfer & Trust Company, as Warrant Agent, or its successor (the "Warrant
Agent"), accompanied by payment of $_____  per share, subject to adjustment (the
"Exercise Price"), in lawful money of the United States of America in cash or by
check made payable to the Warrant Agent for the account of the Company.

          This Warrant Certificate and each Warrant represented hereby are
issued pursuant to and are subject in all respects to the terms and conditions
set forth in the Warrant Agreement (the "Warrant Agreement"), dated ____________
__, 1996, by and between the Company, Pryor, McClendon, Counts & Co., Inc.
("Pryor McClendon") and National Securities Corporation ("National", Pryor
McClendon and National are collectively referred to herein as the
"Representatives") and the Warrant Agent.

          In the event of certain contingencies provided for in the Warrant
Agreement, the Exercise Price and the number of shares of Common Stock subject
to purchase upon the exercise of each Warrant represented hereby are subject to
modification or adjustment.
<PAGE>
 
          Each Warrant represented hereby is exercisable at the option of the
Registered Holder, but no fractional interests will be issued.  In the case of
the exercise of less than all the Warrants represented hereby, the Company shall
cancel this Warrant Certificate upon the surrender hereof and shall execute and
deliver a new Warrant Certificate or Warrant Certificates of like tenor, which
the Warrant Agent shall countersign, for the balance of such Warrants.

          The term "Expiration Date" shall mean 5:00 p.m. (New York time) on the
date which is five (5) years after the Initial Warrant Exercise Date or the date
fixed for redemption hereof, whichever date is earlier.  If each such date shall
in the State of New York be a holiday or a day on which the banks are authorized
to close, then the Expiration Date shall mean 5:00 p.m. (New York time) the next
following day which in the State of New York is not a holiday or a day on which
banks are authorized to close.

          The Company shall not be obligated to deliver any securities pursuant
to the exercise of this Warrant unless a registration statement under the
Securities Act of 1933, as amended (the "Act'), with respect to such securities
is effective or an exemption thereunder is available.  The Company has
covenanted and agreed that it will file a registration statement under the
Federal securities laws, use its best efforts to cause the same to become
effective, use its best efforts to keep such registration statement current, if
required under the Act, while any of the Warrants are outstanding, and deliver a
prospectus which complies with Section 10(a)(3) of the Act to the Registered
Holder exercising this Warrant; provided, however, that (i) if at the time of
                                --------  -------                            
exercise of any of the Warrants the Company does not have in place an effective
registration statement or is otherwise, in the good faith determination of the
Board of Directors of the Company, precluded by applicable laws from issuing the
shares of Common Stock issuable upon such exercise, the Company may, in lieu of
issuance of those shares, elect to redeem the Warrants duly surrendered for
exercise for a price per Warrant equal to the difference between the Market
Price (as defined below) of a share of the Common Stock on the date of such
submission and the Exercise Price, and in the event of such redemption, the
Company will pay to the Registered Holder the above-described redemption price
in cash within 10 business days after receipt of notice from the Warrant Agent
that such Warrants have been submitted for exercise, and (ii) if the Market
Price of the Common Stock is less than the Exercise Price, then the Company need
not take such actions to file a registration statement (or a post-effective
amendment to a registration statement) with respect to the issuance of Common
Stock upon exercise of the Warrants until such time as the Company has been
subject to the requirements of Section 12 or 15(d) of the Securities Exchange
Act of 1934, as amended, for a period of at least twelve calendar months
immediately preceding the filing of the registration statement.  This Warrant
shall not be exercisable by a Registered Holder in any state where such exercise
would be unlawful.

          The term "Market Price" shall mean the last reported sale price, or,
in case no such reported sale takes place on such day, the average of the last
reported sales prices for the last three (3) trading days, in either case as
officially reported by the principal securities exchange on which the 
<PAGE>
 
Common Stock is listed or admitted to trading or by the Nasdaq SmallCap Market,
or, if the Common Stock is not listed or admitted to trading on any national
securities exchange or quoted by the Nasdaq, the average closing bid price as
furnished by the Nasdaq through Nasdaq or similar organization if Nasdaq is no
longer reporting such information, or if the Common Stock is not quoted on
Nasdaq, as determined in good faith (using customary valuation methods) by
resolution of the members of the Board of Directors of the Company, based on the
best information available to it.

          This Warrant Certificate is exchangeable, upon the surrender hereof by
the Registered Holder at the corporate office of the Warrant Agent, for a new
Warrant Certificate or Warrant Certificates of like tenor representing an equal
aggregate number of Warrants, each of such new Warrant Certificates to represent
such number of Warrants as shall be designated by such Registered Holder at the
time of such surrender.  Upon due presentment and payment of any tax or other
charge imposed in connection therewith or incident thereto, for registration of
transfer of this Warrant Certificate at such office, a new Warrant Certificate
or Warrant Certificates representing an equal aggregate number of Warrants will
be issued to the transferee in exchange therefor, subject to the limitations
provided in the Warrant Agreement.

          Prior to the exercise of any Warrant represented hereby, the
Registered Holder shall not be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

          Subject to the provisions of the Warrant Agreement, this Warrant may
be redeemed at the option of the Company, at a redemption price of $0.05 per
Warrant, at any time after the date of the Prospectus, provided that the average
closing sale price for the Common Stock as reported by the Nasdaq Small Cap
Market, if the Common Stock is then traded on the Nasdaq SmallCap Market (or the
average closing sale price, if the Common Stock is then traded on the Nasdaq
National Market or a national securities exchange), shall have equalled or
exceeded $_____ per share [200% of the intial public offering price] for any
twenty (20) consecutive trading days ending on the fifth trading day prior to
the date on which the Notice of Redemption, as defined below, is given (subject
to adjustment in the event of any stock splits or other similar events).  Notice
of redemption (the "Notice of Redemption") shall be given not later than the
thirtieth day before the date fixed for redemption, or as provided in the
Warrant Agreement.  On and after the date fixed for redemption, the Registered
Holder shall have no rights with respect to the Warrants except to receive the
$0.05 per Warrant upon surrender of this Warrant Certificate.

          Upon certain circumstances, the Representatives may be entitled to
receive an aggregate of five percent (5%) of the Exercise Price of the Warrants
represented hereby, if it is engaged as a Warrant solicitation agent by the
Company.
<PAGE>
 
          Prior to due presentment for registration of transfer hereof, the
Company and the Warrant Agent may deem and treat the Registered Holder as the
absolute owner hereof and of each Warrant represented hereby (notwithstanding
any notations of ownership or writing hereon made by anyone other than a duly
authorized officer of the Company or the Warrant Agent) for all purposes and
shall not be affected by any notice to the contrary, except as provided in the
Warrant Agreement.

          This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of California without giving effect to
conflicts of laws.

          This Warrant Certificate is not valid unless countersigned by the
Warrant Agent.

                     1996 EXECUTIVES' EQUITY INCENTIVE PLAN

                            As Adopted _______, 1996


          1.   PURPOSE.  The purpose of this Plan is to provide incentives to
               -------                                                       
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses.  Capitalized terms not defined in the text are defined in Section 23.

          2.   SHARES SUBJECT TO THE PLAN.
               -------------------------- 

               2.1       Number of Shares Available. Subject to Sections 2.2 and
                         --------------------------
18, the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 225,000 Shares. Subject to Sections 2.2 and 18,
Shares that: (a) are subject to issuance upon exercise of an Option but cease to
be subject to such Option for any reason other than exercise of such Option; (b)
are subject to an Award granted hereunder but are forfeited or are repurchased
by the Company at the original issue price; or (c) are subject to an Award that
otherwise terminates without Shares being issued will again be available for
grant and issuance in connection with future Awards under this Plan. At all
times the Company shall reserve and keep available a sufficient number of Shares
as shall be required to satisfy the requirements of all outstanding Options
granted under this Plan and all other outstanding but unvested Awards granted
under this Plan.

               2.2       Adjustment of Shares.  In the event that the number of
                         --------------------                                  
outstanding Shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the shareholders of the
Company and compliance with applicable securities laws; provided, however, that
                                                        --------  -------      
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.

          3.   ELIGIBILITY.  ISO (as defined in Section 5 below) may be granted
               -----------                                                     
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company.  All other Awards may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any Parent or Subsidiary of the
Company; provided such consultants, contractors and advisors render bona fide
         --------                                                            
services not in connection with the offer and sale of securities in a capital-
raising transaction.  Notwithstanding the foregoing, Awards under this Plan
shall be granted only to persons who (i) have a preexisting personal or business
relationship with the Company or any of its officers, directors or controlling
persons, or (ii) by reason of their business or financial experience or the
business or financial experience of their professional advisors who are
unaffiliated with and who are not compensated by the Company or any affiliate or
selling agent of the Company, directly or indirectly, could be reasonably
assumed to have the capacity to protect their own interests in connection with
the transaction.  No person will be eligible to receive more than 100,000 Shares
in any calendar year under this Plan pursuant to the grant of Awards hereunder,
other than new employees of the Company or of a Parent or Subsidiary of the
Company (including new employees who are also officers and directors of the
Company or any Parent or Subsidiary of the Company) who are eligible to receive
up to a maximum of 200,000 Shares in the calendar year in which they commence
their employment.  A person may be granted more than one Award under this Plan.

          4.   ADMINISTRATION.
               --------------

                         -------------------                        
by the Committee or by the Board acting as the Committee. Subject to the general

               other agreement or document executed pursuant to this Plan;

          (f)  determine whether Awards will be granted singly, in combination
               with, in tandem with, in replacement of, or as alternatives to,
               other Awards under this Plan or any other incentive or
               compensation plan of the Company or any Parent or Subsidiary of
               the Company;

          (g)  grant waivers of Plan or Award conditions;

          (h)  determine the vesting, exercisability and payment of Awards;

          (j)  determine whether an Award has been earned; and

          (k)  make all other determinations necessary or advisable for the
               administration of this Plan.

               4.2      Committee Discretion.  Any determination made by the
                        --------------------                                
Committee with respect to any Award will be made in its sole discretion at the
time of grant of the Award or, unless in contravention of any express term of
this Plan or Award, at any later time, and such determination will be final and
binding on the Company and on all persons having an interest in any Award under
this Plan.  The Committee may delegate to one or more officers of the Company
the authority to grant an Award under this Plan to Participants who are not
Insiders of the Company.

               4.3      Committee Members.  If two or more members of the Board
                        -----------------
are Outside Directors, the Committee will be comprised of at least two (2)
members of the Board, all of whom are Outside Directors and who satisfy the
requirements under the Exchange Act for administering this Plan.

          5.   OPTIONS.  The Committee may grant Options to eligible persons and
               -------                                                          
will determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISO") or Nonqualified Stock Options ("NQSOS"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

               5.1       Form of Option Grant.  Each Option granted under this
                         --------------------
Plan will be evidenced by an Award Agreement which will expressly identify the
Option as an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and will be in such form
and contain such provisions (which need not be the same for each Participant) as
the Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.

                                      -2-

                                          1996 Executive's Equity Incentive Plan


               5.2       Date of Grant.  The date of grant of an Option will be
                         -------------
the date on which the Committee makes the determination to grant such Option,
unless otherwise specified by the Committee. The Stock Option Agreement and a
copy of this Plan will be delivered to the Participant within a reasonable time
after the granting of the Option.

               5.3       Exercise Period.  Options may be exercisable within
                         ---------------
the times or upon the events determined by the Committee as set forth in the
Stock Option Agreement governing such Option; provided, however, that no Option
                                              --------  -------
will be exercisable after the expiration of ten (10) years from the date the
Option is granted; and provided further that no ISO granted to a person who
                       -------- -------
directly or by attribution owns more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or of any Parent or
Subsidiary of the Company ("TEN PERCENT SHAREHOLDER") will be exercisable after
the expiration of five (5) years from the date the ISO is granted. The Committee
also may provide for Options to become exercisable at one time or from time to
time, periodically or otherwise, in such number of Shares or percentage of
Shares as the Committee determines.

               5.4       Exercise Price.  The Exercise Price of an Option will
                         --------------
be determined by the Committee when the Option is granted and may be not less
than 85% of the Fair Market Value of the Shares on the date of grant; provided
that: (i) the Exercise Price of an ISO will be not less than 100% of the Fair
Market Value of the Shares on the date of grant; and (ii) the Exercise Price of
any ISO granted to a Ten Percent Shareholder will not be less than 110% of the
Fair Market Value of the Shares on the date of grant. Payment for the Shares
purchased may be made in accordance with Section 8 of this Plan.

               5.5       Method of Exercise.  Options may be exercised only by
                         ------------------                                   
delivery to the Company of a written stock option exercise agreement  (the
"EXERCISE AGREEMENT") in a form approved by the Committee (which need not be the
same for each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company to comply with applicable securities laws, together
with payment in full of the Exercise Price for the number of Shares being
purchased.

               5.6       Termination.  Notwithstanding the exercise periods
                         -----------
set forth in the Stock Option Agreement, exercise of an Option will always be
subject to the following:

          (a)  If the Participant is Terminated for any reason except death,
               Cause or Disability, then the Participant may exercise such
               Participant's Options only to the extent that such Options would
               have been exercisable upon the Termination Date no later than
               three (3) months after the Termination Date (or such shorter or
               longer time period not exceeding five (5) years as may be
               determined by the Committee, with any exercise beyond three (3)
               months after the Termination Date deemed to be an NQSO), but in
               any event, no later than the expiration date of the Options.

          (b)  If the Participant is Terminated because of Participant's death
               or Disability (or the Participant dies within three (3) months
               after a Termination other than for Cause or because of
               Participant's death or Disability), then Participant's Options
               may be exercised only to the extent that such Options would have
               been exercisable by Participant on the Termination Date and must
               be exercised by Participant (or Participant's legal
               representative or authorized assignee) no later than twelve (12)
               months after the Termination Date (or such shorter or longer time
               period not exceeding five (5) years as may be determined by the
               Committee, with any such exercise beyond (a) three (3) months
               after the Termination Date when the Termination is for any reason
               other than the Participant's death or disability, within the
               meaning of Section 22(e)(3) of the Code, or (b) twelve (12)
               months after the Termination Date when the Termination is for
               Participant's death or disability, within the meaning of Section
               22(e)(3) of the Code, deemed to be an NQSO), but in any event no
               later than the expiration date of the Options.

                                          1996 Executive's Equity Incentive Plan


          (c)  If a Participant is Terminated for Cause, unless otherwise
               determined by the Committee, neither the Participant, the
               Participant's estate nor such other person who may then hold the
               Option shall be entitled to exercise any Option with respect to
               any Shares whatsoever, after termination of service, whether or
               not after termination of service the Participant may receive
               payment from the Company or Subsidiary for vacation pay, for
               services rendered prior to termination, for services rendered for
               the day on which termination occurs, for salary in lieu of
               notice, or for any other benefits. In making such determination,
               the Board shall give the Participant an opportunity to present to
               the Board evidence on his behalf. For the purpose of this
               paragraph, termination of service shall be deemed to occur on the
               date when the Company dispatches notice or advice to the
               Participant that his service is terminated.

               5.7       Limitations on Exercise.  The Committee may specify a
                         -----------------------                              
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

               5.8       Limitations on ISO.  The aggregate Fair Market Value
                         ------------------                                  
(determined as of the date of grant) of Shares with respect to which ISO are
exercisable for the first time by a Participant during any calendar year (under
this Plan or under any other incentive stock option plan of the Company, Parent
or Subsidiary of the Company) shall not exceed $100,000.  If the Fair Market
Value of Shares on the date of grant with respect to which ISO are exercisable
for the first time by a Participant during any calendar year would exceed
$100,000, then the Options for the first $100,000 worth of Shares to become
exercisable in such calendar year will be ISO and the Options for the amount in
excess of $100,000 that become exercisable in that calendar year will be NQSOs.
In the event that the Code or the regulations promulgated thereunder are amended
after the Effective Date of this Plan to provide for a different limit on the
Fair Market Value of Shares permitted to be subject to ISO, such different limit
will be automatically incorporated herein and will apply to any Options granted
after the effective date of such amendment.

               5.9       Modification, Extension or Renewal.  The Committee may
                         ----------------------------------                    
modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of a Participant, impair any of such Participant's rights
under any Option previously granted.  Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code.  The Committee may reduce the Exercise Price of
outstanding Options without the consent of Participants affected by a written
notice to them; provided, however, that the Exercise Price may not be reduced
                --------  -------                                            
below the minimum Exercise Price that would be permitted under Section 5.4 of
this Plan for Options granted on the date the action is taken to reduce the
Exercise Price.

               5.10      No Disqualification.  Notwithstanding any other
                         -------------------
provision in this Plan, no term of this Plan relating to ISO will be
interpreted, amended or altered, nor will any discretion or authority granted
under this Plan be exercised, so as to disqualify this Plan under Section 422 of
the Code or, without the consent of the Participant affected, to disqualify any
ISO under Section 422 of the Code.

          6.   RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
               ----------------                                              
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

               6.1       Form of Restricted Stock Award.  All purchases under a
                         ------------------------------                        
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan.  The offer of Restricted Stock will be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agreement is delivered to the person.  If
such person does not execute and deliver the Restricted Stock Purchase

                                          1996 Executive's Equity Incentive Plan


Agreement along with full payment for the Shares to the Company within thirty
(30) days, then the offer will terminate, unless otherwise determined by the
Committee.

               6.2       Purchase Price.  The Purchase Price of Shares sold
                         --------------
pursuant to a Restricted Stock Award will be determined by the Committee and
will be at least 85% of the Fair Market Value of the Shares on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Shareholder, in which case the Purchase Price will be 100% of the Fair Market
Value. Payment of the Purchase Price may be made in accordance with Section 8 of
this Plan.

               6.3       Restrictions.  Restricted Stock Awards will be subject
                         ------------
to such restrictions (if any) as the Committee may impose. The Committee may
provide for the lapse of such restrictions in installments and may accelerate or
waive such restrictions, in whole or part, based on length of service,
performance or such other factors or criteria as the Committee may determine.

          7.   STOCK BONUSES.
               ------------- 

               7.1       Awards of Stock Bonuses.  A Stock Bonus is an award of
                         -----------------------     
Shares (which may consist of Restricted Stock) for services rendered to the
Company or any Parent or Subsidiary of the Company. A Stock Bonus may be awarded
for past services already rendered to the Company, or any Parent or Subsidiary
of the Company pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that
will be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan. A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "PERFORMANCE STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.

               7.2       Terms of Stock Bonuses.  The Committee will determine
                         ----------------------  
the number of Shares to be awarded to the Participant and whether such Shares
will be Restricted Stock. If the Stock Bonus is being earned upon the
satisfaction of performance goals pursuant to a Performance Stock Bonus
Agreement, then the Committee will determine: (a) the nature, length and
starting date of any period during which performance is to be measured (the
"PERFORMANCE PERIOD") for each Stock Bonus; (b) the performance goals and
criteria to be used to measure the performance, if any; (c) the number of Shares
that may be awarded to the Participant; and (d) the extent to which such Stock
Bonuses have been earned. Performance Periods may overlap and Participants may
participate simultaneously with respect to Stock Bonuses that are subject to
different Performance Periods and different performance goals and other
criteria. The number of Shares may be fixed or may vary in accordance with such
performance goals and criteria as may be determined by the Committee. The
Committee may adjust the performance goals applicable to the Stock Bonuses to
take into account changes in law and accounting or tax rules and to make such
adjustments as the Committee deems necessary or appropriate to reflect the
impact of extraordinary or unusual items, events or circumstances to avoid
windfalls or hardships.

               7.3       Form of Payment.  The earned portion of a Stock Bonus
                         ---------------
may be paid currently or on a deferred basis with such interest or dividend
equivalent, if any, as the Committee may determine. Payment may be made in the
form of cash, whole Shares, including Restricted Stock, or a combination
thereof, either in a lump sum payment or in installments, all as the Committee
will determine.

               7.4       Termination During Performance Period.  If a
                         -------------------------------------
Participant is Terminated during a Performance Period for any reason, then such
Participant will be entitled to payment (whether in Shares, cash or otherwise)
with respect to the Stock Bonus only to the extent earned as of the date of
Termination in accordance with the Performance Stock Bonus Agreement, unless the
Committee will determine otherwise.

          8.   PAYMENT FOR SHARE PURCHASES.

                                          1996 Executive's Equity Incentive Plan


               8.1       Payment.  Payment for Shares purchased pursuant to
                         -------
this Plan may be made in cash (by check) or, where expressly approved for the
Participant by the Committee and where permitted by law:

          (a)  by cancellation of indebtedness of the Company to the
               Participant;

          (b)  by surrender of shares that either:  (1) have been owned by
               Participant for more than six (6) months and have been paid for
               within the meaning of SEC Rule 144 (and, if such shares were
               purchased from the Company by use of a promissory note, such note
               has been fully paid with respect to such shares); or (2) were
               obtained by Participant in the public market;

          (c)  by tender of a full recourse promissory note having such terms as
               may be approved by the Committee and bearing interest at a rate
               sufficient to avoid imputation of income under Sections 483 and
               1274 of the Code; provided, however, that Participants who are
                                 --------  -------  
               not employees or directors of the Company will not be entitled to
               purchase Shares with a promissory note unless the note is
               adequately secured by collateral other than the Shares;

          (d)  by waiver of compensation due or accrued to the Participant for
               services rendered;

          (e)  with respect only to purchases upon exercise of an Option, and
               provided that a public market for the Company's stock exists:

               (1)  through a "same day sale" commitment from the Participant
                    and a broker-dealer that is a member of the National
                    Association of Securities Dealers (an "NASD DEALER") whereby
                    the Participant irrevocably elects to exercise the Option
                    and to sell a portion of the Shares so purchased to pay for
                    the Exercise Price, and whereby the NASD Dealer irrevocably
                    commits upon receipt of such Shares to forward the Exercise
                    Price directly to the Company; or

               (2)  through a "margin" commitment from the Participant and a
                    NASD Dealer whereby the Participant irrevocably elects to
                    exercise the Option and to pledge the Shares so purchased to
                    the NASD Dealer in a margin account as security for a loan
                    from the NASD Dealer in the amount of the Exercise Price,
                    and whereby the NASD Dealer irrevocably commits upon receipt
                    of such Shares to forward the Exercise Price directly to the
                    Company; or

          (f)  by any combination of the foregoing.

               8.2       Loan Guarantees.  The Committee may help the
                         ---------------
Participant pay for Shares purchased under this Plan by authorizing a guarantee
by the Company of a third-party loan to the Participant.

          9.   WITHHOLDING TAXES.
               ----------------- 

               9.1       Withholding Generally.  Whenever Shares are to be
                         ---------------------
issued in satisfaction of Awards granted under this Plan, the Company may
require the Participant to remit to the Company an amount sufficient to satisfy
federal, state and local withholding tax requirements prior to the delivery of
any certificate or certificates for such Shares. Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

               9.2       Stock Withholding.  When, under applicable tax laws, a
                         -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a

                                          1996 Executive's Equity Incentive Plan


Participant to have Shares withheld for this purpose will be made in accordance
with the requirements established by the Committee and be in writing in a form
acceptable to the Committee


          10.  PRIVILEGES OF STOCK OWNERSHIP.
               ----------------------------- 

               10.1      Voting and Dividends.  No Participant will have any
of the rights of a shareholder with respect to any Shares until the Shares are
issued to the Participant. After Shares are issued to the Participant, the
Participant will be a shareholder and have all the rights of a shareholder with
respect to such Shares, including the right to vote and receive all dividends or
other distributions made or paid with respect to such Shares; provided, that if
                                                              --------
such Shares are Restricted Stock, then any new, additional or different
securities the Participant may become entitled to receive with respect to such
Shares by virtue of a stock dividend, stock split or any other change in the
corporate or capital structure of the Company will be subject to the same
restrictions as the Restricted Stock; provided, further, that the Participant
                                      --------  -------
will have no right to retain such stock dividends or stock distributions with
respect to Shares that are repurchased at the Participant's original Purchase
Price pursuant to Section 12.

               10.2      Financial Statements.  The Company will provide
                         --------------------
financial statements to each Participant prior to such Participant's purchase of
Shares under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company will not be
                                    --------  -------
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

          11.  TRANSFERABILITY.  Awards granted under this Plan, and any
               ---------------
interest therein, will not be transferable or assignable by Participant, and may
not be made subject to execution, attachment or similar process, otherwise than
by will or by the laws of descent and distribution. During the lifetime of the
Participant an Award will be exercisable only by the Participant, and any
elections with respect to an Award may be made only by the Participant.

          12.  RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
               ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or cancellation of purchase money
indebtedness, at the Participant's Exercise Price or Purchase Price, as the case
may be.

          13.  CERTIFICATES.  All certificates for Shares or other securities
               ------------                                                  
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

          14.  ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
               ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
                                   --------  -------                        
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

         15.  EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or
              -----------------------------                                    
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards.  The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

         16.  SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  An Award will not
              ----------------------------------------------                    
be effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed or quoted, as they are in effect on the date of grant
of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in this Plan, the Company will have no
obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable.  The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company will have no liability for any inability or failure to
do so.

         17.  NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award
              -----------------------                                    
granted under this Plan will confer or be deemed to confer on any Participant
any right to continue in the employ of, or to continue any other relationship
with, the Company or any Parent or Subsidiary of the Company or limit in any way
the right of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

         18.  CORPORATE TRANSACTIONS.
              ---------------------- 

              18.1   Assumption or Replacement of Awards by Successor.  In the
                     ------------------------------------------------         
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the shareholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the shareholders of the Company immediately prior to such merger
(other than any shareholder that merges, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, or (d) the sale of substantially
all of the assets of the Company, any or all outstanding Awards may be assumed,
converted or replaced by the successor corporation (if any), which assumption,
conversion or replacement will be binding on all Participants.  In the
alternative, the successor corporation may substitute equivalent Awards or
provide substantially similar consideration to Participants as was provided to
shareholders (after taking into account the existing provisions of the Awards).
The successor corporation may also issue, in place of outstanding Shares of the
Company held by the Participant, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the Participant.  In the
event such successor corporation (if any) refuses to assume or substitute
Awards, as provided above, pursuant to a transaction described in this
Subsection 18.1, such Awards will expire on such transaction at such time and on
such conditions as the Board will determine.

              18.2   Other Treatment of Awards.  Subject to any greater rights
                     -------------------------                                
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, sale of assets or other
"corporate transaction."

              18.3   Assumption of Awards by the Company. The Company, from time
                     -----------------------------------
to time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other

                                      -8-

                                                             Isonics Corporation
                                          1996 Executives' Equity Incentive Plan


company's award; or (b) assuming such award as if it had been granted under this
Plan if the terms of such assumed award could be applied to an Award granted
under this Plan. Such substitution or assumption will be permissible if the
holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(except that the exercise price and the number and nature of Shares issuable
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code). In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

         19.  ADOPTION AND SHAREHOLDER APPROVAL.  This Plan will become
              ---------------------------------                        
effective on the date on which the registration statement filed by the Company
with the SEC under the Securities Act registering the initial public offering of
the Company's Common Stock is declared effective by the SEC (the "EFFECTIVE
DATE"); provided, however, that if the Effective Date does not occur on or
        --------  -------                                                 
before December 31, 1997, this Plan will terminate having never become
effective.  This Plan shall be approved by the shareholders of the Company
(excluding Shares issued pursuant to this Plan), consistent with applicable
laws, within twelve (12) months before or after the date this Plan is adopted by
the Board.  Upon the Effective Date, the Board may grant Awards pursuant to this
Plan; provided, however, that: (a) no Option may be exercised prior to initial
      --------  -------                                                       
shareholder approval of this Plan; (b) no Option granted pursuant to an increase
in the number of Shares subject to this Plan approved by the Board will be
exercised prior to the time such increase has been approved by the shareholders
of the Company; and (c) in the event that shareholder approval of such increase
is not obtained within the time period provided herein, all Awards granted
hereunder will be canceled, any Shares issued pursuant to any Award will be
canceled, and any purchase of Shares hereunder will be rescinded.  So long as
the Company is subject to Section 16(b) of the Exchange Act, the Company will
comply with the requirements of Rule 16b-3 (or its successor), as amended, with
respect to shareholder approval.

         20.  TERM OF PLAN/GOVERNING LAW.  Unless earlier terminated as provided
              --------------------------                                        
herein, this Plan will terminate ten (10) years from the date this Plan is
adopted by the Board or, if earlier, the date of shareholder approval.  This
Plan and all agreements thereunder shall be governed by and construed in
accordance with the laws of the State of California.

         21.  AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
              --------------------------------                            
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; provided, however, that the Board will not, without the approval
              --------  -------                                               
of the shareholders of the Company, amend this Plan in any manner that requires
such shareholder approval pursuant to the Code or the regulations promulgated
thereunder as such provisions apply to ISO plans or (if the Company is subject
to the Exchange Act or Section 16(b) of the Exchange Act) pursuant to the
Exchange Act or Rule 16b-3 (or its successor), as amended, thereunder,
respectively.

         22.  NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by
              --------------------------                                       
the Board, the submission of this Plan to the shareholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

         23.  DEFINITIONS.  As used in this Plan, the following terms will have
              -----------                                                      
the following meanings:

              "AWARD" means any award under this Plan, including any Option,
Restricted Stock or Stock Bonus.

              "AWARD AGREEMENT" means, with respect to each Award, the signed
written agreement between the Company and the Participant setting forth the
terms and conditions of the Award.

              "BOARD" means the Board of Directors of the Company.

                                                      1996 Equity Incentive Plan


         (c)  If the Participant is terminated for Cause, then Participant's
              options shall expire on such Participant's Termination Date, or at
              such later time or on such conditions as determined by the
              Committee.

              5.7  Limitations on Exercise.  The Committee may specify a
                   -----------------------                              
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

              5.8  Limitations on ISO.  The aggregate Fair Market Value
                   ------------------                                  
(determined as of the date of grant) of Shares with respect to which ISO are
exercisable for the first time by a Participant during any calendar year (under
this Plan or under any other incentive stock option plan of the Company, Parent
or Subsidiary of the Company) shall not exceed $100,000.  If the Fair Market
Value of Shares on the date of grant with respect to which ISO are exercisable
for the first time by a Participant during any calendar year would exceed
$100,000, then the Options for the first $100,000 worth of Shares to become
exercisable in such calendar year will be ISO and the Options for the amount in
excess of $100,000 that become exercisable in that calendar year will be NQSOs.
In the event that the Code or the regulations promulgated thereunder are amended
after the Effective Date of this Plan to provide for a different limit on the
Fair Market Value of Shares permitted to be subject to ISO, such different limit
will be automatically incorporated herein and will apply to any Options granted
after the effective date of such amendment.

              5.9  Modification, Extension or Renewal.  The Committee may
                   ----------------------------------                    
modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of a Participant, impair any of such Participant's rights
under any Option previously granted.  Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code.  The Committee may reduce the Exercise Price of
outstanding Options without the consent of Participants affected by a written
notice to them; provided, however, that the Exercise Price may not be reduced
                --------  -------                                            
below the minimum Exercise Price that would be permitted under Section 5.4 of
this Plan for Options granted on the date the action is taken to reduce the
Exercise Price.

              5.10 No Disqualification.  Notwithstanding any other provision in
                   -------------------                                         
this Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

         6.   RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
              ----------------                                              
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

              6.1  Form of Restricted Stock Award.  All purchases under a
                   ------------------------------                        
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan.  The offer of Restricted Stock will be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agreement is delivered to the person.  If
such person does not execute and deliver the Restricted Stock Purchase Agreement
along with full payment for the Shares to the Company within thirty (30) days,
then the offer will terminate, unless otherwise determined by the Committee.

              6.2  Purchase Price.  The Purchase Price of Shares sold pursuant
                   --------------                                             
to a Restricted Stock Award will be determined by the Committee and will be at
least 85% of the Fair Market Value of the Shares on the date the Restricted
Stock Award is granted, except in the case of a sale to a Ten Percent
Shareholder, in which case the Purchase Price will be 100% of the Fair Market
Value.  Payment of the Purchase Price may be made in accordance with Section 8
of this Plan.

                                                      1996 Equity Incentive Plan


              6.3  Restrictions.  Restricted Stock Awards will be subject to
                   ------------                                             
such restrictions (if any) as the Committee may impose.  The Committee may
provide for the lapse of such restrictions in installments and may accelerate or
waive such restrictions, in whole or part, based on length of service,
performance or such other factors or criteria as the Committee may determine.

         7.   STOCK BONUSES.
              ------------- 

              7.1  Awards of Stock Bonuses.  A Stock Bonus is an award of Shares
                   -----------------------                                      
(which may consist of Restricted Stock) for services rendered to the Company or
any Parent or Subsidiary of the Company.  A Stock Bonus may be awarded for past
services already rendered to the Company, or any Parent or Subsidiary of the
Company pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will
be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan.  A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "PERFORMANCE STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan.  Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.

              7.2  Terms of Stock Bonuses.  The Committee will determine the
                   ----------------------                                   
number of Shares to be awarded to the Participant and whether such Shares will
be Restricted Stock.  If the Stock Bonus is being earned upon the satisfaction
of performance goals pursuant to a Performance Stock Bonus Agreement, then the
Committee will determine:  (a) the nature, length and starting date of any
period during which performance is to be measured (the "PERFORMANCE PERIOD") for
each Stock Bonus; (b) the performance goals and criteria to be used to measure
the performance, if any; (c) the number of Shares that may be awarded to the
Participant; and (d) the extent to which such Stock Bonuses have been earned.
Performance Periods may overlap and Participants may participate simultaneously
with respect to Stock Bonuses that are subject to different Performance Periods
and different performance goals and other criteria.  The number of Shares may be
fixed or may vary in accordance with such performance goals and criteria as may
be determined by the Committee.  The Committee may adjust the performance goals
applicable to the Stock Bonuses to take into account changes in law and
accounting or tax rules and to make such adjustments as the Committee deems
necessary or appropriate to reflect the impact of extraordinary or unusual
items, events or circumstances to avoid windfalls or hardships.

              7.3  Form of Payment.  The earned portion of a Stock Bonus may be
                   ---------------                                             
paid currently or on a deferred basis with such interest or dividend equivalent,
if any, as the Committee may determine.  Payment may be made in the form of
cash, whole Shares, including Restricted Stock, or a combination thereof, either
in a lump sum payment or in installments, all as the Committee will determine.

              7.4  Termination During Performance Period.  If a Participant is
                   -------------------------------------                      
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Stock Bonus only to the extent earned as of the date of Termination in
accordance with the Performance Stock Bonus Agreement, unless the Committee
determines otherwise.

         8.   PAYMENT FOR SHARE PURCHASES.
              --------------------------- 

              8.1  Payment.  Payment for Shares purchased pursuant to this Plan
                   -------

by the Committee and where permitted by law:

         (a)  by cancellation of indebtedness of the Company to the Participant;

         (b)  by surrender of shares that either:  (1) have been owned by
              Participant for more than six (6) months and have been paid for
              within the meaning of SEC Rule 144 (and, if such shares

              note has been fully paid with respect to such shares); or (2) were
              obtained by Participant in the public market;

         (c)  by tender of a full recourse promissory note having such terms as
              may be approved by the Committee and bearing interest at a rate
              sufficient to avoid imputation of income under Sections 483 and
              1274 of the Code; provided, however, that Participants who are not
                                --------  -------                               
              employees or directors of the Company will not be entitled to
              purchase Shares with a promissory note unless the note is
              adequately secured by collateral other than the Shares;

         (d)  by waiver of compensation due or accrued to the Participant for
              services rendered;

         (e)  with respect only to purchases upon exercise of an Option, and
              provided that a public market for the Company's stock exists:

              (1)  through a "same day sale" commitment from the Participant and
                   a broker-dealer that is a member of the National Association
                   of Securities Dealers (an "NASD DEALER") whereby the
                   Participant irrevocably elects to exercise the Option and to
                   sell a portion of the Shares so purchased to pay for the
                   Exercise Price, and whereby the NASD Dealer irrevocably
                   commits upon receipt of such Shares to forward the Exercise
                   Price directly to the Company; or

              (2)  through a "margin" commitment from the Participant and a NASD
                   Dealer whereby the Participant irrevocably elects to exercise
                   the Option and to pledge the Shares so purchased to the NASD
                   Dealer in a margin account as security for a loan from the
                   NASD Dealer in the amount of the Exercise Price, and whereby
                   the NASD Dealer irrevocably commits upon receipt of such
                   Shares to forward the Exercise Price directly to the Company;
                   or

         (f)  by any combination of the foregoing.

              8.2  Loan Guarantees.  The Committee may help the Participant pay
                   ---------------                                             
for Shares purchased under this Plan by authorizing a guarantee by the Company
of a third-party loan to the Participant.

         9.   WITHHOLDING TAXES.
              ----------------- 

              9.1  Withholding Generally.  Whenever Shares are to be issued in
                   ---------------------                                      
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares.  Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

              9.2  Stock Withholding.  When, under applicable tax laws, a
                   -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee

         10.  PRIVILEGES OF STOCK OWNERSHIP.

provided, that if such Shares are Restricted Stock, then any new, additional or
- --------
different securities the Participant may become entitled to receive with respect
to such Shares by virtue of a stock dividend, stock split or any other change in
the corporate or capital structure of the Company will be subject to the same
restrictions as the Restricted Stock; provided, further, that the Participant
                                      --------  -------

              ---------------                                                   
therein, will not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution.  During the lifetime of the
Participant an Award will be exercisable only by the Participant, and any
elections with respect to an Award may be made only by the Participant.

         12.  RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
              ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase Unvested Shares held by a Participant following such
Participant's Termination at any time within ninety (90) days after
Participant's Termination Date for cash and/or cancellation of purchase money
indebtedness, at the Participant's Exercise Price or Purchase Price, as the case
may be, provided, that to the extent the Participant is not an officer, director
        --------                                                                
or consultant of the Company, such right of repurchase lapses at the rate of at
least twenty percent (20%) per year over five (5) years from:  (A) the date of
grant of the Option or (B) in the case of Restricted Stock, the date the
Participant purchases the Shares.

         13.  CERTIFICATES.  All certificates for Shares or other securities
              ------------

              ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, (other than Shares with respect to which
consideration has been fully paid by the Participant (in forms other than by
promissory notes) and received by the Company), together with stock powers or
other instruments of transfer approved by the Committee, appropriately endorsed
in blank, with the Company or an agent designated by the Company to hold in
escrow until such restrictions have lapsed or terminated, and the Committee may
cause a legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
                                   --------  -------                        
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

         15.  EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or
              -----------------------------

              ----------------------------------------------                    
be effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed or quoted, as they are in effect on the date of grant
of the Award and also on the date of exercise or other issuance.

obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable.  The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company will have no liability for any inability or failure to
do so.

         17.  NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award
              -----------------------                                    
granted under this Plan will confer or be deemed to confer on any Participant
any right to continue in the employ of, or to continue any other relationship
with, the Company or any Parent or Subsidiary of the Company or limit in any way
the right of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

         18.  CORPORATE TRANSACTIONS.
              ---------------------- 

              18.1  Assumption or Replacement of Awards by Successor.  In the
                    ------------------------------------------------         
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the shareholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the shareholders of the Company immediately prior to such merger
(other than any shareholder that merges, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, or (d) the sale of substantially
all of the assets of the Company, any or all outstanding Awards may be assumed,
converted or replaced by the successor corporation (if any), which assumption,
conversion or replacement will be binding on all Participants.  In the
alternative, the successor corporation may substitute equivalent Awards or
provide substantially similar consideration to Participants as was provided to
shareholders (after taking into account the existing provisions of the Awards).
The successor corporation may also issue, in place of outstanding Shares of the
Company held by the Participant, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the Participant.  In the
event such successor corporation (if any) refuses to assume or substitute
Awards, as provided above, pursuant to a transaction described in this
Subsection 18.1, such Awards will expire on such transaction at such time and on
such conditions as the Board will determine.

               18.2 Other Treatment of Awards.  Subject to any greater rights
                    -------------------------                                
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, sale of assets or other
"corporate transaction."

               18.3 Assumption of Awards by the Company.  The Company, from time
                    -----------------------------------                         
to time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan.  Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant.  In the event the Company assumes an award

granted by another company, the terms and conditions of such award will remain
unchanged (except that the exercise price and the number and nature of Shares
           ------
issuable upon exercise of any such option will be adjusted appropriately
pursuant to Section 424(a) of the Code). In the event the Company elects to
grant a new Option rather than assuming an existing option, such new Option may
be granted with a similarly adjusted Exercise Price.

with the SEC under the Securities Act registering the initial public offering of
the Company's Common Stock is declared effective by the SEC (the "EFFECTIVE
DATE"); provided, however, that if the Effective Date does not occur on or

effective.  This Plan shall be approved by the shareholders of the Company
(excluding Shares issued pursuant to this Plan), consistent with applicable
laws, within twelve (12) months before or after the date this Plan is adopted by
the Board.  Upon the Effective Date, the Board may grant Awards pursuant to this
Plan; provided, however, that: (a) no Option may be exercised prior to initial

shareholder approval of this Plan; (b) no Option granted pursuant to an increase
in the number of Shares subject to this Plan approved by the Board will be
exercised prior to the time such increase has been approved by the shareholders
of the Company; and (c) in the event that shareholder approval of such increase
is not obtained within the time period provided herein, all Awards granted
hereunder will be canceled, any Shares issued pursuant to any Award will be
canceled, and any purchase of Shares hereunder will be rescinded.  So long as
the Company is subject to Section 16(b) of the Exchange Act, the Company will
comply with the requirements of Rule 16b-3 (or its successor), as amended, with
respect to shareholder approval.

terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant

              --------  -------                                               
of the shareholders of the Company, amend this Plan in any manner that requires
such shareholder approval pursuant to the Code or the regulations promulgated
thereunder as such provisions apply to ISO plans or (if the Company is subject
to the Exchange Act or Section 16(b) of the Exchange Act) pursuant to the
Exchange Act or Rule 16b-3 (or its successor), as amended, thereunder,
respectively.

         22.  NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by
              --------------------------                                       
the Board, the submission of this Plan to the shareholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

includes the sale of all of the Warrant Shares.

          2.2    Other Company Registration. Subject to Article IV hereof, if
                 --------------------------
the registration statement described in Section 2.1 is not effective, then at
any time after the date of this Agreement the Company determines to register,
either for its own account or the account of any security holder or holders, any
of its common stock on a form that would also permit the registration of
Registrable Securities (expressly excluding any public offering relating solely
to Form S-8 for employee benefit plans or Form S-4 for certain business
combinations, or their successor forms, or any form that does not permit
secondary offerings), other than the Company's IPO registration and the
registration described in Section 2.1 above, the Company shall, each such time,
promptly give each Holder written notice of such determination. Upon the written
request of every Holder electing to participate, with each such request given
within ten (10) days after mailing of any such notice by the Company, the
Company shall use its best efforts to include in such registration (and any
related qualification under blue sky laws, and in any underwriting) all of the
Registrable Securities that the Participating Holders have requested be
registered, subject to the provisions of Section 8.1 of this Agreement.

          2.3    Company's Notice. For each Company registration pursuant to

Section 2.1 or 2.2, the Company shall state in a written notice to the Holders
those jurisdictions in which the Company intends to attempt to qualify such
securities under applicable blue sky laws. The Company may withdraw any
registration pursuant to this Article II at any time prior to the effectiveness
of the Registration Statement whether or not any Holder has elected to
participate. Subject to the provisions of Article VIII hereof, each Holder may
participate in an unlimited number of registrations pursuant to this Article II.


                                  ARTICLE III
                          OBLIGATIONS OF THE COMPANY

          3.1    Obligations of the Company. Whenever required under Article II
                 --------------------------
to use its best efforts to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

          3.1.1  Prepare and file with the SEC a Registration Statement with
     respect to such Registrable Securities as promptly as possible and use all
     reasonable efforts to cause such Registration Statement to become and
     remain effective until the Participating Holders have completed the
     distribution described in the Registration Statement or, with 
<PAGE>
 
     respect to any Participating Holder, at such time as such Holder's Warrant
     Shares are no longer Registrable Securities.

          3.1.2  Use all reasonable efforts to prepare and file with the SEC
     such amendments (including post-effective 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 Act with respect to the disposition of all securities covered by such
     Registration Statement, subject to a Waiting Period (as defined in Section
     8.2.2 hereof), if applicable;

          3.1.3  Keep the Participating Holders advised as to the progress of
     the registration and offering, and furnish to the Holders, at any time and
     from time to time, such numbers of copies of a Prospectus, including a
     preliminary prospectus, amendments or supplements, in conformity with the
     requirements of the Act, and such other documents as any of them from time
     to time may reasonably request in order to facilitate the disposition of
     Registrable Securities owned by the Participating Holders;

          3.1.4  Subject to the procedures described in Section 8.2.2, prepare
     and furnish to such Holder a reasonable number of copies of a supplement to
     or an amendment of such Prospectus as may be necessary so that, as
     thereafter delivered to the purchasers of such shares, such Prospectus
     shall not include an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading or incomplete in the light of the
     circumstances than existing;

          3.1.5  Cause all such Registrable Securities registered pursuant
     hereunder to be listed on each securities exchange on which similar
     securities issued by the Company are then listed;

          3.1.6  Provide a transfer agent and registrar for all Registrable
     Securities registered pursuant to such registration statement and a CUSIP
     number of all such Registrable Securities, in each case not later than the
     effective date of such registration; and

          3.1.7  Use all reasonable efforts to register and qualify the
     securities covered by such Registration Statement under such other
     securities or Blue Sky laws of such jurisdictions as shall be reasonably
     appropriate for the distribution of the securities covered by the
     Registration Statement, provided that the Company shall not be required to
     register or qualify the securities in any jurisdiction where the Company,
     in connection with such registration or qualification or as a condition
     thereto, is required to qualify to do business or to file a general consent
     to service of process (unless the Company is already subject to service in
     such jurisdiction and except as required by the Act) or in any jurisdiction
     where the Company did not register and qualify the sale of its securities
     in the IPO or where the Common Stock is not otherwise already approved for
     secondary trading in that state, and further provided that (anything in
     this Agreement to the contrary notwithstanding with respect to the bearing
     of expenses) if any jurisdiction in which the securities shall be qualified
     shall require that expenses incurred in connection with the 
<PAGE>
 
     qualification of the securities in that jurisdiction be borne by selling
     shareholders, then such expenses shall be payable by the Participating
     Holders, pro rata, to the extent required by such jurisdiction.

     3.2  Furnish Information.  It shall be a condition precedent to the
          -------------------                                           
obligations of the Company to take any action pursuant to this Agreement with
respect to any Participating Holder that such person furnish to the Company such
information regarding such person, the Registrable Securities held by such
person, and the intended method of disposition of such securities as the Company
shall reasonably request and as shall be required in connection with the action
to be taken by the Company.

     3.3  Expenses of Registration.  All expenses incurred in connection with
          ------------------------                                           
any registration effected hereunder (excluding underwriters' discounts and
commissions and stock transfer taxes), including without limitation all
registration and qualification fees and printing, legal and accounting fees and
costs, shall be borne by the Company.  In addition, the Company shall bear the
reasonable attorneys' fees and costs incurred by the Participating Holders up to
an aggregate amount of $10,000.


                                  ARTICLE IV
                           UNDERWRITING REQUIREMENTS

     4.1  Underwriting. If any registration hereunder shall involve an
          ------------
underwriting, then the Company shall so advise all Holders in writing, and the
right of any Holder to participate in any registration hereunder shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. The Company, together with all Holders who intend to
distribute their Registrable Securities through such underwriting, shall enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by the Company. Except as otherwise
provided in Section 2.1 hereof, if the underwriter or underwriters determine
that marketing factors require a limitation on the number of shares of Common
Stock to be underwritten, then the Company shall so advise all Participating
Holders. The Company shall be entitled to include all securities it proposed to
register for its own account in its notice to Holders, and the number of shares
of Registrable Securities which may thereafter be included in the registration
and underwriting shall be allocated first, as nearly as practical, among the
Participating Holders and other selling stockholders whose shares are included
as a result of registration rights granted by the Company, in proportion to the
number of securities held by each such person at the time of the initial filing
of the Registration Statement, and then to other participants, as may be agreed
by such other participants.

     4.2  Withdrawal. No Registrable Securities excluded from the underwriting
          ----------
by reason of this Article IV shall be included in such registration. If any
person disapproves of the terms of the underwriting, such person may elect to
withdraw therefrom by written notice to the Company and the underwriter or
underwriters. All Registrable Securities so withdrawn shall also be withdrawn
from the registration and shall not be transferred in a public distribution
prior to one 
<PAGE>
 
hundred and eighty (180) days after the effective date of the Registration
Statement relating thereto or such other shorter period of time as the
underwriter or underwriters may require.


                                   ARTICLE V
                                INDEMNIFICATION

          5.1    Indemnification by Company. To the extent permitted by law, the
                 -------------------------- 
Company will indemnify and hold harmless each of the Holders, each of the
Holder's respective partners, officers, directors, employees, heirs, successors,
assigns and agents, and each Person, if any, who controls any Holder within the
meaning of either Section 15 of the Act or Section 20 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act") (each such person being sometimes
hereinafter referred to as an "Indemnified Holder"), from and against any and
all losses, claims, damages, liabilities and expenses (or actions, proceedings
or settlements with respect thereto) including reasonable costs of investigation
and legal fees and expenses, (i) arising out of or based upon any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement or Prospectus (or in any amendment or supplement thereto
or in any preliminary prospectus) or any document relating thereto, or (ii)
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or (iii) arising out of or based upon any violation by
the Company of the Act or any rule or regulation thereunder applicable to the
Company and the relating action or inaction required of the Company in
connection therewith, and the Company will reimburse each Holder, each of its
partners, officers, directors, employees, heirs, successors, assigns and agents,
and each person controlling such Holder, for any and all legal and other
expenses reasonably incurred in connection with investigating, defending or
settling such loss, claim, damage or liability. Notwithstanding the above, this
indemnity and duty to defend shall not apply to any Holder to the extent that
such losses, claims, damages, liabilities or expenses arise out of or are based
upon any untrue statement or omission or allegation thereof based upon
information furnished in writing to the Company by such Holder expressly for use
in any Registration Statement or Prospectus, or any amendment or supplement
thereto, or any preliminary prospectus, or given supplementally to the SEC, the
National Association of Securities Dealers, any exchange or state securities
regulators. Further, the Company shall not be liable nor have any duty to defend
in any such case to the extent that any such loss, claim, damage, liability or
expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in any preliminary prospectus if
(i) such Indemnified Holder failed to send or deliver a copy of the Prospectus
with or prior to the delivery of written confirmation of the sale of Registrable
Securities, and (ii) the Prospectus would have completely corrected such untrue
statement or omission. Further, the Company shall not be liable nor have any
duty to defend in any case to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission in the Prospectus if
such untrue statement or alleged untrue statement, omission or alleged omission
is completely corrected in an amendment or supplement to the Prospectus and if,
having previously been furnished by or on behalf of the Company with copies of
the Prospectus as so amended or supplemented, such Indemnified Holder thereafter
fails to deliver such Prospectus as so amended or supplemented, prior to or
concurrently with the sale of a Registrable Security to the person asserting
such loss, 
<PAGE>
 
claim, damage, liability or expense who purchased such Registrable Security
which is the subject thereof from such Indemnified Holder. This indemnity will
be in addition to any liability which the Company may otherwise have. This
indemnity shall not apply to any amount paid or incurred in settlement without
the express written consent of the Company, which consent shall not be
unreasonably withheld.

          Each Indemnified Holder shall give prompt notice to the Company after
it has actual knowledge of any claim in respect of which indemnity may be sought
from the Company hereunder.  After receipt of such notice, the Company may
assume the defense thereof at the Company's expense, provided that counsel for
the Company shall be satisfactory to such Indemnified Holder (whose approval
shall not be unreasonably withheld).  The failure of any Indemnified Holder to
give notice as provided herein shall not relieve the Company of any of its
obligations hereunder to the extent such failure is not prejudicial.  If the
Company assumes the defense in such action, such Indemnified Holder shall retain
the right to employ separate counsel in any such action and to participate in
the defense thereof, but the fees and expenses of such counsel shall be the
expense of such Indemnified Holder unless (i) the Company has expressly agreed
in writing to pay such fees and expenses, or (ii) the Company shall have a duty
to assume the defense of such action or proceeding and has failed to do so and
failed to employ counsel satisfactory to such Indemnified Holder in any such
action or proceeding as required hereunder, or (iii) the named parties to any
such action or proceeding (including any impleaded parties) include both the
Indemnified Holder and the Company, and such Indemnified Holder shall have been
advised by counsel that there is a conflict of interest between the Company and
the Indemnified Holder making representation by the same counsel inappropriate.
In all circumstances, if the Indemnified Holder notifies the Company in writing
that it elects to employ separate counsel at the expense of the Company, the
Company shall not have the obligation to assume the defense of such action or
proceeding on behalf of such Indemnified Holder; it being understood, however,
that the Company shall not, in connection with any one such action or proceeding
or separate but substantially similar or related actions or proceedings in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for such Indemnified Holder, which firm shall be
designated in writing by such Indemnified Holder and shall be subject to the
approval of the Company, which approval shall not be unreasonably withheld.  The
Company shall not be liable for any settlement of any such action or proceeding
effected without its written consent, but if settled with its written consent,
or if there be a final judgment for the plaintiff in any such action or
proceeding, the Company agrees to indemnify and hold harmless such Indemnified
Holder from and against any loss or liability by reason of such settlement or
judgment.

          5.2    Indemnification by Holders. To the extent permitted by law,
                 --------------------------
each of the Holders agrees to indemnify and hold harmless the Company, its
directors, employees, officers and agents, and each person, if any, who controls
the Company within the meaning of either Section 15 of the Act or Section 20 of
the Exchange Act, and each other Holder, and each other Holder's partners,
officers, directors, employees, heirs, successors, assigns and agents and each
person controlling such Holder, to the same extent as the foregoing indemnity
from the Company to the Indemnified Holders, but only with respect to
information relating to each Holder furnished in writing by such Holder
expressly for use in any Registration Statement or Prospectus, or any 
<PAGE>
 
amendment or supplement thereto, or any preliminary prospectus, or given
supplementally to the SEC, the National Association of Securities Dealers, any
exchange or state securities regulators. In case any action or proceeding shall
be brought in respect of which indemnity may be sought against any Holder
hereunder, (a) such Holder shall have the rights and duties given the Company,
and (b) the Company and its directors, officers, employees or agents and
controlling persons shall have the rights and duties given to each Indemnified
Holder by paragraph 5.1. In no event shall the liability of any Holder hereunder
be greater in amount than the dollar amount of the proceeds received by such
Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

          5.3  Contribution.  If the indemnification provided for in this
               ------------
Article V is unavailable to an indemnified party under paragraphs 5.1 or 5.2
hereof (other than by reason of exceptions provided in those paragraphs) in
respect of any losses, claims, damages or liabilities referred to therein, then
each applicable indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages or liabilities in such proportion as
is appropriate to reflect the relative fault of the Company, on the one hand,
and of the Indemnified Holder or Holders, on the other hand, in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company on the one hand and of the Indemnified Holder or
Holders on the other shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Indemnified Holder or Holders 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 the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in
paragraph 5.1, any legal or other fees or expenses reasonably incurred by such
party in connection with investigating or defending any action or claim. The
Company, and the Holders agree that it would not be just and equitable if
contribution pursuant to this paragraph 5.3 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to herein. Notwithstanding the provisions
of this paragraph 5.3, no Holder shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities sold by such Holder and distributed to the public were offered to the
public exceeds the amount of any damages which such Holder has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

          5.4  Survival. All provisions of this Article V shall survive the
               --------
expiration or termination of this Agreement for any reason.

                                   ARTICLE VI
                              TERM AND TERMINATION

          6.1  Termination of the Company's Obligations. The Company's
               ----------------------------------------
obligations pursuant to Articles II and III shall expire September 30, 2003 or
until there are no longer any Registrable Securities outstanding.


                                  ARTICLE VII
                               RULE 144 REPORTING

          7.1  Reports Under Exchange Act. With a view to making available to
               --------------------------
Holders the benefits of Rule 144 promulgated under the Act ("Rule 144") and any
other rule or regulation of the SEC that may at any time permit the Holders to
sell securities of the Company to the public without registration, the Company
agrees to use its best efforts to:

               7.1.1  make and keep public information available, as those terms
          are understood and defined in Rule 144, at all times subsequent to
          ninety (90) days after the effective date of the first registration
          statement covering a public offering of the Company's securities filed
          with the SEC by the Company;

               7.1.2  file with the SEC, in a timely manner, all reports and
          other documents required of the Company under the Act and the Exchange
          Act; and

               7.1.3  so long as such person owns any Registrable Securities,
          furnish to the Holders forthwith upon request, a written statement by
          the Company that it has complied with the reporting requirements of
          Rule 144 (at any time after ninety (90) days after the effective date
          of said first registration statement filed by the Company), and of the
          Act and the Exchange Act (at any time after it has become subject to
          such reporting requirements), (ii) a copy of the most recent annual or
          quarterly report of the Company, and (iii) such other reports and
          documents so filed by the Company as may be reasonably requested in
          availing the Holders of any rule or regulation of the SEC permitting
          the selling of any such securities without registration.


                                  ARTICLE VIII
                           OBLIGATIONS OF THE HOLDERS

          8.1  Lockup Agreement. In consideration for the Company agreeing to
               ----------------
its obligations hereunder, each of the Holders agrees in connection with the
initial registration of the Company's Common Stock for sale to the general
public and, upon the request of the Company or the Company's underwriters
managing any underwritten offering of the Company's securities, not to sell,
make short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any shares of Common Stock or other equity securities now owned or
hereafter acquired by Holder (other than those included in the registration)
without the prior written consent of the Company
<PAGE>
 
or such underwriters, as the case may be, for such period of time (not to exceed
one year) from the effective date of such registration as the Company or the
Company's underwriters may specify. If the Holder is to be so obligated, each
Holder agrees to execute and deliver such documentation as may be reasonably
required by the underwriters in connection with this Article VIII. This
restriction shall not apply to a registration relating solely to employee
benefit plans on Form S-8 or similar successor forms, or a registration relating
solely to a Rule 145 transaction on Form S-4 or similar successor forms. In any
registered offering after the initial offering, the Holders shall agree to a
similar "lockup" of their shares (other than those included in the registration)
provided the lockup period does not exceed 180 days.

          8.2  Notice of Proposed Transfers. The rights to cause the Company to
               ----------------------------
register securities under Articles I and II hereunder shall be transferable or
assignable only to a transferee or assignee of Registrable Securities (as
presently constituted and subject to adjustments for stock splits, stock
dividends, and the like) equal to not less than 1% of the Company's outstanding
common stock or all of the Registrable Securities held by the transferor
Purchasers, subject to the following:

               8.2.1  Prior to any proposed sale, assignment, transfer or pledge
          of any Registrable Securities (other than a transfer not involving a
          change in beneficial ownership) unless there is in effect a
          registration statement under the Act covering the proposed transfer,
          the Holder thereof shall give 10 calendar days' prior written notice
          to the Company of such Holder's intention to effect such transfer,
          sale, assignment or pledge in sufficient detail, and, if requested by
          the Company, such notice shall be accompanied, at such Holder's
          expense, by either (i) an unqualified written opinion of legal counsel
          who shall be, and whose legal opinion shall be, reasonably
          satisfactory to the Company, addressed to the Company, to the effect
          that the proposed transfer of the Registrable Securities may be
          effected without registration under the Act, or (ii) a "no action"
          letter from the SEC to the effect that the transfer of such securities
          without registration will not result in a recommendation by the staff
          of the SEC that action be taken with respect thereto.

               8.2.2  If a Holder proposes to sell any Registrable Securities
          pursuant to an effective Registration Statement, such Holder shall
          give ten (10) calendar days' prior written notice (a "Sale Notice") to
          the Company of such Holder's intention to effect such sale, and if
          within such ten (10) calendar day period the Company provides written
          notice to such Holder that a sale at such time would, in the Company's
          good faith judgment, be inadvisable due to the possible existence of
          material undisclosed information relating to the Company's business
          operations and instructs such Holder not to sell such Registrable
          Securities for a specified time not to exceed 30 calendar days (the
          "Waiting Period"), then such Holder shall not sell such Registrable
          Securities until the earlier of (i) such Holder's receipt of written
          notice from the Company that such Holder may sell such Registrable
          Securities, or (ii) the expiration of the Waiting Period. The Company
          may impose the Waiting Period for only one proposed sale per quarter
          by such Holder.

               8.2.3  After such Holder complies with the requirements of this
          Section 8, such Holder shall be entitled to transfer such Registrable
          Securities in accordance with the 
<PAGE>
 
          terms of the notice delivered by the Holder to the Company. It is
          agreed that the Company will not request an opinion of counsel for the
          Holder for transactions made in reliance on Rule 144 under the Act as
          to which no notice shall be necessary, so long as appropriate Rule 144
          representations by such Holder and his or its broker are provided to
          the Company. Each certificate evidencing the Registrable Securities
          transferred as above provided shall bear the appropriate restrictive
          legend except that such certificate shall not bear any restrictive
          legend if, in the opinion of counsel for such Holder and the Company,
          such legend is not required in order to establish compliance with any
          provision of the Act. Notwithstanding the foregoing, each Holder
          agrees that it will not request that a transfer of the Registrable
          Securities be made (or that any legend be removed from the certificate
          evidencing the Registrable Securities) solely in reliance on Rule
          144(k) under the Act if as a result of such proposed transfer, the
          Company would be rendered subject to the reporting requirements of the
          Exchange Act.

          8.3  No Right to Delay.  No Holder shall have any right to take any
               -----------------
action to restrain, enjoin, or otherwise delay any registration as a result of
any controversy under this Agreement.


                                   ARTICLE IX
                                 MISCELLANEOUS

          9.1  Assignment. The terms and conditions of this Agreement shall be
               ----------
binding upon and inure to the benefit of all of the respective successors,
transferees and assigns of the parties hereto who agree to be bound by all of
the terms of this Agreement. This Agreement shall be binding upon the parties
with respect to shares of capital stock subsequently acquired by any Holder.

          9.2  Entire Agreement; Amendment; Waiver. This Agreement (including
               -----------------------------------
the Exhibits hereto, if any) constitutes the full and entire understanding and
agreement between the parties with regard to the subjects hereof and thereof.
Neither this Agreement nor any term hereof may be amended, waived, discharged or
terminated, except by a written instrument signed by the Company and the Holders
of at least a majority of the then outstanding Registrable Securities and any
such amendment, waiver, discharge or termination shall be binding on all the
Holders, but in no event shall the obligation of any Holder hereunder the
materially increased, except upon the written consent of such Holder.

          9.3  Information Confidential. Each Holder acknowledges that the
               ------------------------
information received by it pursuant hereto may be confidential and for its use
only, and it will not use such confidential information in violation of the
Exchange Act or reproduce, disclose or disseminate such information to any other
person (other than its employees or agents having a need to know the contents of

                                      -4-
<PAGE>
 
           3.2   Benefits.  Officer shall be entitled to a minimum of four weeks
                 --------
of paid vacation leave per annum.  Officer shall be entitled to carry over
and/or accrue a maximum of two weeks of unused vacation in any year for use in
the following year.  To the extent not used or accrued as set forth in the
preceding sentence, unused vacation shall not carry over or accrue into any
following year and shall be forfeited without compensation.  As Officer becomes
eligible therefor, Officer shall have the right to participate in and receive
officer benefits including, without limitation, health insurance benefits and
life insurance benefits pursuant to the terms of all present and future benefit
plans specified in Employer's policies (as such policies may be amended from
time to time) and generally made available to similarly situated officers of
Employer.  The amount and extent of benefits to which Officer is entitled shall
be governed by the specific benefit plan, as amended.  Except as otherwise
provided in this Agreement, nothing contained in this Agreement shall prevent
Employer from changing or eliminating any benefit(s) during the Contract Period
as Employer, in its sole discretion, may deem necessary or desirable; provided,
however, any such changes or eliminations of benefits shall be applicable to all
similarly situated officers.  All compensation and comparable payments to be
paid to Officer pursuant to this Agreement shall be less withholdings required
by law.

           3.3   Incentive Compensation.  Officer shall be eligible to receive
                 ----------------------
incentive compensation up to 50% of Officer's annual prevailing salary in the
year to which such award relates, as approved from time to time by the Employer
on the terms and conditions and subject to the limitations of the Employer's
Executive Compensation Plan, as the same may be amended by Employer in its
discretion from time to time.

           3.4   Expenses.  Employer shall reimburse Officer for reasonable 
                 --------
out-of-town travel and other business expenses incurred by Officer in the
performance of Officer's duties, in accordance with Employer's policies, as such
policies may be amended from time to time in Employer's sole discretion.

           3.5   Bonuses and Loans.  Employer and Officer acknowledge that 
                 -----------------
before  the date of this Agreement, Officer exercised a previously-granted 
stock option (the "Option") to acquire 750,000 shares (the "Exercised Shares") 
                   ------                                   ----------------
of Employer's Common Stock, and that in connection with exercise of the Option, 
Employer loaned to Officer a principal amount of $165,000, constituting a
purchase price for the Exercised Shares, such loan evidenced by a promissory
note (the "Exercise Note") given by Officer to Employer. The Exercise Note bears
           -------------    
interest, payable annually, at a rate equal to the minimum applicable federal
rate.  In addition, Employer acknowledges that by virtue of exercise of the
Option, Officer will incur federal and state income tax liability, and may incur
alternative minimum tax ("AMT") liability.  Employer agrees to loan to Officer
                          ---
an amount equal to the federal and state income tax and AMT liability paid by
Officer as a result of Officer's exercise of the Option.  Such loan shall be
made after the amount of such tax liability is determined, but before Officer
pays such amounts to applicable federal and state tax authorities.  Such loan
shall be evidenced by a promissory note (the "Tax Note").  The Tax Note shall
                                              --------    
have a term of five years, shall be unsecured, and shall bear interest, payable
annually, at the minimum applicable federal rate.  In addition, Employer
acknowledges that as a result of exercise of the Option, Officer was obligated
to deliver to the Company an amount equal to the amount 

                                      -5-
<PAGE>
 
required to be withheld by Employer under applicable federal and state
withholding laws, and that Employer has loaned to Officer an amount equal to the
amount required to be delivered by Officer to Employer as a result of such
withholding obligations. The promissory note evidencing such loan (the
"Withholding Note") has a term of five years, is unsecured, and bears interest,
 ----------------
payable annually, at the minimum applicable federal rate. Employer shall pay to
Officer, as bonus compensation, an amount equal to the amount of interest
payments that Officer pays to Employer pursuant to the Exercise Note, Tax Note
and Withholding Note, such bonus payments to be paid on or before the date on
which Officer makes each such interest payments to Employer.

     4.    Severance Compensation.
           ---------------------- 

           4.1   Termination Other Than For Cause or Termination Upon a Change 
                 -------------------------------------------------------------
in Control.  If Officer's employment is terminated in a Termination Other Than 
- ----------
For Cause, then Employer shall continue to pay Officer an amount equal to his
base salary under Section 3 of this Agreement, less applicable withholding
taxes, payable on the Company's normal payroll dates, in the following amounts:

                 (a)  If the Termination Other Than For Cause occurs before 18
          months from the Contract Period Expiration Date, then 18 months of
          base salary;

                 (b)  If the Termination Other Than For Cause occurs within 18
          months before expiration of the Contract Period Expiration Date, then
          a number of months of base salary equal to the remaining number of
          months between the date of termination and the Contract Period
          Expiration Date, but no less than six (6) months of base salary; and

                 (c)  If the Termination Other Than For Cause occurs after the
          Contract Period Expiration Date, then six (6) months of base salary.

     If Officer secures other employment during the period that payments
pursuant to this Section are payable, the Company will be entitled to set off,
dollar for dollar, whatever is earned in such employment against the amount owed
to Officer hereunder.  During the period that severance compensation is payable
hereunder, Officer shall notify Employer of any such employment and any such
other earnings.  In addition, Officer shall have the option, at Officer's own
expense, to extend the health insurance coverage that was provided by Employer
to Officer as an Employee of Employer immediately before the date of
termination, for a period of eighteen (18) months from the date of termination
pursuant to the terms and conditions of COBRA.  Officer shall have sixty (60)
days from the date of termination to notify Employer in writing of Officer's
election to so continue Officer's health insurance coverage.  Should Officer so
elect, Employer shall reimburse Officer for the cost of the premiums under such
health insurance plans under COBRA for a period of six (6) months after the
termination date.  After such time, until eighteen (18) months from the date of
termination, Officer may, if Officer so elects, participate in Employer's health
insurance plans to the extent permitted by COBRA and the terms of such plans,
but any such participation shall be at Officer's sole expense.

           4.2   Accelerated Exercisability of Options.  (i) If Officer's 
                 -------------------------------------
employment is terminated in a Termination Other Than For Cause, or (ii) upon a 
Change in Control, all options 

                                      -6-
<PAGE>
 
granted to Officer shall vest and be fully exercisable as of the date of such
termination, for the period of time after such termination that is specified in
the applicable option agreements relating to such options, and all rights of
repurchase in favor of Employer with respect to such shares shall terminate in
their entirety. Officer may, in his sole discretion, waive the provisions of the
preceding sentence at any time (including, without limitation, if Officer
believes that application of the preceding sentence would jeopardize pooling of
interests treatment of a transaction constituting a Change in Control), so that
the exercisability of such options, and Employer's rights of repurchase with
respect to shares issued or issuable upon exercise of such options, remain
unchanged.

           4.3   Termination Obligations.
                 -----------------------

                 (a)  Officer agrees that all of Employer's property (including,
without limitation, all Employer's equipment, tangible items containing Employer
Proprietary Information (as described below), documents, books, records,
reports, notes, contracts, lists, computer disks (and other computer-generated
files and data), and copies thereof, created on any medium) furnished to,
obtained by, or prepared by Officer in the course of or incident to Officer's
employment shall be returned promptly to Employer upon termination of Officer's
employment.  Nothing contained or implied in this Section shall apply to or
affect any Officer Intellectual Property (as defined below).

                 (b)  The parties' respective representations, warranties, and
obligations contained in this Agreement shall survive the termination of
Officer's employment.

                 (c)  Following any termination of the Officer's employment,
Officer shall fully cooperate with Employer in reasonable respects in all
matters relating to Officer's continuing obligations under this Agreement.

                 (d)  Termination of Officer's employment with Employer during
the Contract Period by Employer for "Cause" shall not affect or impair the
rights or remedies against Officer.

     5.    Employer Proprietary Information.
           -------------------------------- 

           5.1   Defined.  "Employer Confidential Information" is all 
                 -------    ---------------------------------
information, ideas, and concepts in whatever form, tangible or intangible, 
pertaining in any manner to the business of Employer, or any person or entity
that directly or indirectly controls, is controlled by, or is under common
control with, Employer (an "affiliate") or the respective officers, clients,
customers, suppliers, consultants, or business associates of Employer or any
affiliate of Employer, which information, idea(s), or concept(s) have been, or
shall have been, produced by any officer or employee of, or consultant to,
Employer in the course of his or her employment or otherwise produced or
acquired by or on behalf of Employer, that is not generally known outside of
Employer's organization or is so known only through improper means.  Without
limiting the foregoing definition, Employer Proprietary Information shall
include, but not be limited to, the following, to the extent confidential or
proprietary to Employer: (i) confidential or proprietary formulas, manufacturing
processes, teaching and development techniques, processes, trade

                                      -7-
<PAGE>
 
secrets, computer programs, electronic codes, inventions, improvements, and
research projects; (ii) information about costs, profits, markets, or sales, and
lists of vendors, suppliers, customers, or clients; (iii) business, marketing,
and strategic plans; and (iv) officer personnel files and compensation
information.

           5.2   General Restrictions on Use.  While employed by Employer, 
                 ---------------------------
Officer shall use and disclose Employer Confidential Information only for the
benefit of Employer and as is necessary to carry out Officer's responsibilities
under this Agreement.  Following termination of Officer's employment with
Employer, Officer shall not use or disclose any Employer Confidential
Information, except as expressly authorized in writing by Employer.  The
restrictions contained above in this Section shall be inapplicable to any
Employer Confidential Information to the extent that such information: (i) is or
becomes publicly known through no wrongful act of Officer; (ii) is rightfully
received by Officer from a third party without breach of any obligation to
Employer; (iii) is approved for release by written authorization of Employer;
(iv) is distributed or made available to others by Employer without restriction
as to use or disclosure.  Officer shall have no right or license, express,
implied or by estoppel, under any trademark, copyright patent or other
intellectual property right now or hereafter owned or controlled by Employer.

           5.3   Prior Actions and Knowledge.  As of the date of this Agreement,
                 ---------------------------
Officer represents and warrants that from the time of Officer's first employment
with Employer to the date of this Agreement, Officer has held in confidence all
Employer Confidential Information and has not disclosed any Employer
Confidential Information, directly or indirectly, to anyone outside of Employer,
or used, copied, published, or summarized any Employer Confidential Information,
except in the proper conduct of Employer's business.

           5.4   Third-Party Information.  Officer acknowledges that Employer 
                 -----------------------
has received, and in the future will receive, from third parties such parties'
confidential information subject to a duty on Employer's part to maintain the
confidentiality of such information and to use it only for certain limited
purposes.  Officer agrees that Officer owes Employer and such third parties,
while employed by Employer and thereafter, a duty to hold all such confidential
information in confidence and not to disclose or use it, except as necessary to
perform Officer's obligations hereunder and as is consistent with Employer's
agreements with such third parties.

     6.    Competitive Activity.
           -------------------- 

           6.1   Acknowledgment.  Officer acknowledges that the pursuit of other
                 --------------
employment after the term of this Agreement could involve the use or disclosure
of Employer Confidential Information in breach of Section 5 but that proof of
such a breach would be extremely difficult.

           6.2   Prohibited Activity.  To forestall the above-described
                 -------------------
disclosure, use, and breach, Officer agrees that (i) during Officer's employment
by Employer and for a period of twelve (12) months after the date of termination
of Officer's employment with Employer, Officer shall not, directly or
indirectly, (A) divert or attempt to divert from Employer (or any affiliate of
Employer) any business of any kind in which it is engaged, including, without
limitation, the 

                                      -8-
<PAGE>
 
solicitation of or interference with any of its customers or suppliers; or (B)
employ, solicit for employment, or recommend for employment any person employed
by Employer (or any affiliate of Employer); and (ii) during Officer's employment
by Employer, for a period of 12 months after a Termination for Cause and for the
period after the date of termination of Officer's employment with Employer (in
any termination other than a Termination For Cause) that Officer is entitled to
receive severance payments from Employer, engage in any business activity that
is competitive with the actual or actively anticipated business of Employer in
any state in the United States or in any foreign country where Employer conducts
its business, unless the action allegedly in contravention of this subsection
was done without the use in any way of Employer Proprietary Information.

     7.    Miscellaneous.
           ------------- 

           7.1   Notices.  Any notice permitted and required to be given 
                 -------

under this Agreement by Employer including, without limitation, exercise of
discretion, consents, waivers, and amendments to this Agreement shall be made

     7.3   Integration.  This Agreement is intended to be the final, complete,
           -----------
and exclusive statement of the terms of Officer's employment by Employer. This
Agreement may not be contradicted by evidence of any prior or contemporaneous

     7.4   Amendments; Waivers.  This Agreement may not be modified, amended, or
           -------------------
terminated except by an instrument in writing signed by Officer and signed by an
officer of Employer specifically authorized by the Board of Directors to execute
such instrument.  No failure to exercise, and no delay in exercising, any right,
remedy, or power under this Agreement shall operate as a waiver thereof, and no
single or partial exercise of any right, remedy, or power under this Agreement
shall preclude any other or further exercise thereof or the exercise of any
other right, remedy, or power provided herein or at law or in equity.

     7.5   Assignment; Successors and Assigns.  Officer agrees that Officer will
           ----------------------------------
not assign, sell, transfer, delegate, or otherwise dispose of, whether
voluntarily or involuntarily, or by operation of law, any rights or obligations
under this Agreement. Any such purported assignment, transfer, or delegation
shall be null and void.  Nothing in this Agreement shall prevent the
consolidation of Employer with, or its merger into, any other entity, or the
sale by Employer of all or substantially all of its assets, or the assignment by
Employer of any rights or obligations under this Agreement; provided, however,
no assignment by Employer shall release or discharge Employer from any of its
obligations under this Agreement.  Subject to the foregoing, this Agreement
shall be binding upon and shall inure to the benefit of the parties and their
respective heirs, legal representatives, successors, and permitted assigns and
shall not benefit any person or entity other than those specifically enumerated
in this Agreement.

     7.6   Severability.  If any provision of this Agreement, or its application
           ------------
to any person, place, or circumstance, is held by a court of competent
jurisdiction to be invalid, unenforceable, or void, such provision shall be
enforced to the greatest extent permitted by law and the remainder of this
Agreement and such provision as applied to other persons, places, and
circumstances shall remain in full force and effect.

     7.7   Attorneys' Fees.  In any legal action, or proceeding brought to
           ---------------
enforce the terms of this Agreement, the prevailing party in such legal action
or proceeding shall be entitled to recover its reasonable attorneys' fees and
costs from the other party.

     7.8   Injunctive Relief.  If either party breaches or threatens to breach
           -----------------
any of his or its respective obligations under Sections 4, 5, or 6 of this
Agreement, the parties acknowledge that the damage or imminent damage would be
irreparable and extremely difficult to estimate, making any remedy at law or for
damages inadequate.  Accordingly, in such circumstances a party shall be
entitled to injunctive relief against the other party in the event of any such
breach or threatened breach in addition to any other relief (including damages)
available under this Agreement or at law.

     7.9   Governing Law; Consent to Jurisdiction.  This Agreement shall be 
           --------------------------------------    
governed by and construed in accordance with the laws of the State of California

exclusive jurisdiction and venue of the state and federal courts located in San
Jose, California for purposes of any legal action.  Service upon either party in
any such action may be made by first class mail, certified or registered, in the
manner provided for delivery of notices in this Agreement.

     7.10  Counterparts.  This Agreement may be executed in one or more
           ------------
counterparts, all of which taken together shall constitute one and the same
Agreement.

rendered by Officer to Employer under this Agreement, Employer shall pay Officer
a salary of at least $180,000 per year, payable semi-monthly or otherwise
pursuant to Employer's normal payroll procedures. Employer shall review annually
Officer's compensation in accordance with Employer's established administrative
practices for adjusting salaries for similarly situated employees; provided,
however, that nothing in this Section shall impose any obligation on Employer to
increase Officer's base compensation; and provided further, that Employee's
salary shall not be reduced during the term of this Agreement to an amount less
than $180,000 per year.

                                      -4-
<PAGE>
 
         3.2  Benefits.  Officer shall be entitled to a minimum of four weeks of
              -------- 
paid vacation leave per annum.  Officer shall be entitled to carry over and/or
accrue a maximum of two weeks of unused vacation in any year for use in the
following year.  To the extent not used or accrued as set forth in the preceding
sentence, unused vacation shall not carry over or accrue into any following year
and shall be forfeited without compensation.  As Officer becomes eligible
therefor, Officer shall have the right to participate in and receive officer
benefits including, without limitation, health insurance benefits and life
insurance benefits pursuant to the terms of all present and future benefit plans
specified in Employer's policies (as such policies may be amended from time to
time) and generally made available to similarly situated officers of Employer.
The amount and extent of benefits to which Officer is entitled shall be governed
by the specific benefit plan, as amended.  Except as otherwise provided in this
Agreement, nothing contained in this Agreement shall prevent Employer from
changing or eliminating any benefit(s) during the Contract Period as Employer,
in its sole discretion, may deem necessary or desirable; provided, however, any
such changes or eliminations of benefits shall be applicable to all similarly
situated officers.  All compensation and comparable payments to be paid to
Officer pursuant to this Agreement shall be less withholdings required by law.

         3.3  Incentive Compensation.  Officer shall be eligible to receive
              ----------------------
incentive compensation up to 50% of Officer's annual prevailing salary in the
year to which such award relates, as approved from time to time by the Employer
on the terms and conditions and subject to the limitations of the Employer's
Executive Compensation Plan, as the same may be amended by Employer in its
discretion from time to time.

         3.4  Expenses.  Employer shall reimburse Officer for reasonable out-of-
              --------
town travel and other business expenses incurred by Officer in the performance
of Officer's duties, in accordance with Employer's policies, as such policies
may be amended from time to time in Employer's sole discretion.

         3.5  Bonuses and Loans.  Employer and Officer acknowledge that before
              -----------------
the date of this Agreement, Officer exercised a previously-granted stock option
(the "Option") to acquire 750,000 shares (the "Exercised Shares") of Employer's
      ------                                   ----------------
Common Stock, and that in connection with exercise of the Option, Employer
loaned to Officer a principal amount of $165,000, constituting a purchase price
for the Exercised Shares, such loan evidenced by a promissory note (the
"Exercise Note") given by Officer to Employer. The Exercise Note bears interest,
 -------------
payable annually, at a rate equal to the minimum applicable federal rate. In
addition, Employer acknowledges that by virtue of exercise of the Option,
Officer will incur federal and state income tax liability, and may incur
alternative minimum tax ("AMT") liability. Employer agrees to loan to Officer an
                          ---
amount equal to the federal and state income tax and AMT liability paid by
Officer as a result of Officer's exercise of the Option. Such loan shall be made
after the amount of such tax liability is determined, but before Officer pays
such amounts to applicable federal and state tax authorities. Such loan shall be
evidenced by a promissory note (the "Tax Note"). The Tax Note shall have a term
                                     --------
of five years, shall be unsecured, and shall bear interest, payable annually, at
the minimum applicable federal rate. In addition, Employer acknowledges that as
a result of exercise of the Option, Officer was obligated to deliver to the
Company an amount equal to the amount required to be withheld by Employer under
applicable federal and state withholding laws, and that Employer has loaned to
Officer an amount equal to the amount 

                                      -5-
<PAGE>
 
required to be delivered by Officer to Employer as a result of such withholding
obligations. The promissory note evidencing such loan (the "Withholding Note")
has a term of five years, is unsecured, and bears interest, payable annually, at
the minimum applicable federal rate. Employer shall pay to Officer, as bonus
compensation, an amount equal to the amount of interest payments that Officer
pays to Employer pursuant to the Exercise Note, Tax Note and Withholding Note,
such bonus payments to be paid on or before the date on which Officer makes each
such interest payments to Employer.

     4.   Severance Compensation.
          ---------------------- 

          4.1  Termination Other Than For Cause or Termination Upon a Change in
               ---------------------------------------------------------------- 
Control.  If Officer's employment is terminated in a Termination Other Than For
- -------
Cause, then Employer shall continue to pay Officer an amount equal to his base
salary under Section 3 of this Agreement, less applicable withholding taxes,
payable on the Company's normal payroll dates, in the following amounts:

               (a)  If the Termination Other Than For Cause occurs before 18
          months from the Contract Period Expiration Date, then 18 months of
          base salary;

               (b)  If the Termination Other Than For Cause occurs within 18
          months before expiration of the Contract Period Expiration Date, then
          a number of months of base salary equal to the remaining number of
          months between the date of termination and the Contract Period
          Expiration Date, but no less than six (6) months of base salary; and

               (c)  If the Termination Other Than For Cause occurs after the
          Contract Period Expiration Date, then six (6) months of base salary.

     If Officer secures other employment during the period that payments
pursuant to this Section are payable, the Company will be entitled to set off,
dollar for dollar, whatever is earned in such employment against the amount owed
to Officer hereunder.  During the period that severance compensation is payable
hereunder, Officer shall notify Employer of any such employment and any such
other earnings.  In addition, Officer shall have the option, at Officer's own
expense, to extend the health insurance coverage that was provided by Employer
to Officer as an Employee of Employer immediately before the date of
termination, for a period of eighteen (18) months from the date of termination
pursuant to the terms and conditions of COBRA.  Officer shall have sixty (60)
days from the date of termination to notify Employer in writing of Officer's
election to so continue Officer's health insurance coverage.  Should Officer so
elect, Employer shall reimburse Officer for the cost of the premiums under such
health insurance plans under COBRA for a period of six (6) months after the
termination date.  After such time, until eighteen (18) months from the date of
termination, Officer may, if Officer so elects, participate in Employer's health
insurance plans to the extent permitted by COBRA and the terms of such plans,
but any such participation shall be at Officer's sole expense.

          4.2  Accelerated Exercisability of Options.  (i) If Officer's
               -------------------------------------     
employment is terminated in a Termination Other Than For Cause, or (ii) upon a
Change in Control, all options
                                      -6-
<PAGE>
 
granted to Officer shall vest and be fully exercisable as of the date of such
termination, for the period of time after such termination that is specified in
the applicable option agreements relating to such options, and all rights of
repurchase in favor of Employer with respect to such shares shall terminate in
their entirety. Officer may, in his sole discretion, waive the provisions of the
preceding sentence at any time (including, without limitation, if Officer
believes that application of the preceding sentence would jeopardize pooling of
interests treatment of a transaction constituting a Change in Control), so that
the exercisability of such options, and Employer's rights of repurchase with
respect to shares issued or issuable upon exercise of such options, remain
unchanged.

          4.3  Termination Obligations.

               (a)  Officer agrees that all of Employer's property (including,
without limitation, all Employer's equipment, tangible items containing Employer
Proprietary Information (as described below), documents, books, records,
reports, notes, contracts, lists, computer disks (and other computer-generated
files and data), and copies thereof, created on any medium) furnished to,
obtained by, or prepared by Officer in the course of or incident to Officer's
employment shall be returned promptly to Employer upon termination of Officer's
employment. Nothing contained or implied in this Section shall apply to or
affect any Officer Intellectual Property (as defined below).

               (b)  The parties' respective representations, warranties, and
obligations contained in this Agreement shall survive the termination of
Officer's employment.

               (c)  Following any termination of the Officer's employment,
Officer shall fully cooperate with Employer in reasonable respects in all
matters relating to Officer's continuing obligations under this Agreement.

               (d)  Termination of Officer's employment with Employer during the
Contract Period by Employer for "Cause" shall not affect or impair the rights or
remedies against Officer.

     5.   Employer Proprietary Information.

          5.1  Defined.  "Employer Confidential Information" is all information,
               -------    ---------------------------------
ideas, and concepts in whatever form, tangible or intangible, pertaining in any
manner to the business of Employer, or any person or entity that directly or
indirectly controls, is controlled by, or is under common control with, Employer
(an "affiliate") or the respective officers, clients, customers, suppliers,
     ---------
consultants, or business associates of Employer or any affiliate of Employer,
which information, idea(s), or concept(s) have been, or shall have been,
produced by any officer or employee of, or consultant to, Employer in the course
of his or her employment or otherwise produced or acquired by or on behalf of
Employer, that is not generally known outside of Employer's organization or is
so known only through improper means.  Without limiting the foregoing
definition, Employer Proprietary Information shall include, but not be limited
to, the following, to the extent confidential or proprietary to Employer:  (i)
confidential or proprietary formulas, manufacturing processes, teaching and
development techniques, processes, trade 

                                      -7-
<PAGE>
 
secrets, computer programs, electronic codes, inventions, improvements, and
research projects; (ii) information about costs, profits, markets, or sales, and
lists of vendors, suppliers, customers, or clients; (iii) business, marketing,
and strategic plans; and (iv) officer personnel files and compensation
information.

          5.2  General Restrictions on Use.  While employed by Employer, Officer
               ---------------------------
shall use and disclose Employer Confidential Information only for the benefit of
Employer and as is necessary to carry out Officer's responsibilities under this
Agreement.  Following termination of Officer's employment with Employer, Officer
shall not use or disclose any Employer Confidential Information, except as
expressly authorized in writing by Employer.  The restrictions contained above
in this Section shall be inapplicable to any Employer Confidential Information
to the extent that such information:  (i) is or becomes publicly known through
no wrongful act of Officer; (ii) is rightfully received by Officer from a third
party without breach of any obligation to Employer; (iii) is approved for
release by written authorization of Employer; (iv) is distributed or made
available to others by Employer without restriction as to use or disclosure.
Officer shall have no right or license, express, implied or by estoppel, under
any trademark, copyright patent or other intellectual property right now or
hereafter owned or controlled by Employer.

          5.3  Prior Actions and Knowledge.  As of the date of this Agreement,
               ---------------------------
Officer represents and warrants that from the time of Officer's first employment
with Employer to the date of this Agreement, Officer has held in confidence all
Employer Confidential Information and has not disclosed any Employer
Confidential Information, directly or indirectly, to anyone outside of Employer,
or used, copied, published, or summarized any Employer Confidential Information,
except in the proper conduct of Employer's business.

          5.4  Third-Party Information.  Officer acknowledges that Employer has
               -----------------------
received, and in the future will receive, from third parties such parties'
confidential information subject to a duty on Employer's part to maintain the
confidentiality of such information and to use it only for certain limited
purposes.  Officer agrees that Officer owes Employer and such third parties,
while employed by Employer and thereafter, a duty to hold all such confidential
information in confidence and not to disclose or use it, except as necessary to
perform Officer's obligations hereunder and as is consistent with Employer's
agreements with such third parties.

     6.   Competitive Activity.
          --------------------

          6.1  Acknowledgment.  Officer acknowledges that the pursuit of other
               --------------
employment after the term of this Agreement could involve the use or disclosure
of Employer Confidential Information in breach of Section 5 but that proof of
such a breach would be extremely difficult.

          6.2  Prohibited Activity.  To forestall the above-described
               -------------------
disclosure, use, and breach, Officer agrees that (i) during Officer's employment
by Employer and for a period of twelve (12) months after the date of termination
of Officer's employment with Employer, Officer shall not, directly or
indirectly, (A) divert or attempt to divert from Employer (or any affiliate of
Employer) any business of any kind in which it is engaged, including, without
limitation, the 

                                      -8-
<PAGE>
 
solicitation of or interference with any of its customers or suppliers; or (B)
employ, solicit for employment, or recommend for employment any person employed
by Employer (or any affiliate of Employer); and (ii) during Officer's employment
by Employer, for a period of 12 months after a Termination for Cause and for the
period after the date of termination of Officer's employment with Employer (in
any termination other than a Termination For Cause) that Officer is entitled to
receive severance payments from Employer, engage in any business activity that
is competitive with the actual or actively anticipated business of Employer in
any state in the United States or in any foreign country where Employer conducts
its business, unless the action allegedly in contravention of this subsection
was done without the use in any way of Employer Proprietary Information.

     7.   Miscellaneous.

     7.3  Integration.  This Agreement is intended to be the final, complete,
          -----------
and exclusive statement of the terms of Officer's employment by Employer. This
Agreement may not be contradicted by evidence of any prior or contemporaneous

     7.4  Amendments; Waivers.  This Agreement may not be modified, amended, or
          -------------------
terminated except by an instrument in writing signed by Officer and signed by an
officer of Employer specifically authorized by the Board of Directors to execute
such instrument.  No failure to exercise, and no delay in exercising, any right,
remedy, or power under this Agreement shall operate as a waiver thereof, and no
single or partial exercise of any right, remedy, or power under this Agreement
shall preclude any other or further exercise thereof or the exercise of any
other right, remedy, or power provided herein or at law or in equity.

     7.5  Assignment; Successors and Assigns.  Officer agrees that Officer will
          ----------------------------------
not assign, sell, transfer, delegate, or otherwise dispose of, whether
voluntarily or involuntarily, or by operation of law, any rights or obligations
under this Agreement. Any such purported assignment, transfer, or delegation
shall be null and void. Nothing in this Agreement shall prevent the
consolidation of Employer with, or its merger into, any other entity, or the
sale by Employer of all or substantially all of its assets, or the assignment by
Employer of any rights or obligations under this Agreement; provided, however,
no assignment by Employer shall release or discharge Employer from any of its
obligations under this Agreement. Subject to the foregoing, this Agreement shall
be binding upon and shall inure to the benefit of the parties and their
respective heirs, legal representatives, successors, and permitted assigns and
shall not benefit any person or entity other than those specifically enumerated
in this Agreement.

     7.6  Severability.  If any provision of this Agreement, or its application
          ------------
to any person, place, or circumstance, is held by a court of competent
jurisdiction to be invalid, unenforceable, or void, such provision shall be
enforced to the greatest extent permitted by law and the remainder of this
Agreement and such provision as applied to other persons, places, and
circumstances shall remain in full force and effect.

     7.7  Attorneys' Fees.  In any legal action, or proceeding brought to
          ---------------

or proceeding shall be entitled to recover its reasonable attorneys' fees and

     7.8  Injunctive Relief.  If either party breaches or threatens to breach
          -----------------
any of his or its respective obligations under Sections 4, 5, or 6 of this
Agreement, the parties acknowledge that the damage or imminent damage would be
irreparable and extremely difficult to estimate, making any remedy at law or for
damages inadequate. Accordingly, in such circumstances a party shall be entitled
to injunctive relief against the other party in the event of any such breach or
threatened breach in addition to any other relief (including damages) available
under this Agreement or at law.

     7.9  Governing Law; Consent to Jurisdiction.  This Agreement shall be
          --------------------------------------
governed by and construed in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed within the State

exclusive jurisdiction and venue of the state and federal courts located in San
Jose, California for purposes of any legal action. Service upon either party in
any such action may be made by first class mail, certified or registered, in the
manner provided for delivery of notices in this Agreement.

Agreement.
