historic results and could cause actual results in the future to differ
significantly from the results anticipated in forward looking statements made in
this Prospectus, including documents incorporated herein by reference, in future
filings by BioLase with the Commission, in BioLase's press releases and in oral
statements made by authorized officers of BioLase.  When used in this

                                  THE COMPANY
    
     BioLase Technology, Inc., a Delaware corporation ("BioLase" and, together
with its consolidated subsidiary, the "Company"), designs, develops,
manufactures and markets laser-based systems for use in dental and medical
applications. The current generation of the Company's laser-based systems
incorporates its proprietary technology ("HydroKinetic(TM)") into its surgical
tissue cutting system ("Millennium(TM)"), which utilizes electromagnetic energy
laser pulses from an erbium, chromium: yttrium scandium gallium garnet ("Er,Cr:
YSGG") laser and a proprietary air-water spray. In a configuration utilizing
higher power settings, the laser pulses act to rapidly energize and transform
atomized water droplets from the air-water spray into smaller, high-speed
mechanical cutting water particles, and the Millennium(TM) system, when
operating in this manner, is intended for use primarily in hard tissue
applications. In a configuration utilizing lower power settings, the Er,Cr: YSGG
laser incorporated into the Millennium(TM) system acts as a conventional laser,
with the air-water spray serving as a cooling agent. When operating in this
manner, the Millennium(TM) system is intended for use in soft tissue
applications. The Millennium(TM) system is currently marketed in the United
States and Europe for hard and soft tissue dental applications. See "Risk
Factors -- Need to Establish Marketing Arrangements for Millennium". In October
1998, the United States Food and Drug Administration (the "FDA") granted
clearance to the Company for the marketing of Millennium(TM) for certain hard
tissue applications. In July 1997, the Company received clearance from the FDA
to market a laser-based surgical tissue cutting system in the United States for
a broad range of dermatological and general surgical soft tissue applications.
In response to this clearance, the Company intends to introduce to the domestic
market, a laser-based system in a configuration that is designed for
dermatologic, aesthetic and surgical applications under the name DermaLase(TM)
late in the third quarter of 1999. The Company supports its earlier generations
of laser-based systems with replacement parts and service. The Company also has
(i) an automated system used in endodontic procedures for locating and shaping
root canals, known as the Canal Finder System(TM), which the Company markets
along with a full range of other proprietary and non-proprietary endodontic
products, and (ii) an air-water spray laser accessory, LaserSpray(TM), designed
to cool the tissue receiving laser energy and the surrounding tissue, that is
incorporated into the Company's laser-based systems and can be employed with
fiber-coupled laser systems manufactured by others. In August 1998, the Company
introduced its first consumer product, the LazerSmile(TM) Tooth Whitening
System, which utilizes a monochromatic optical energy light source embedded
within a toothbrush in conjunction with a clear, non-abrasive tooth whitening
gel. The Company has recognized a nominal amount of revenue from sales of
LazerSmile(TM) to date. The Company is currently selling LazerSmile(TM) over the
Internet and through advertising in professional journals, and is also
attempting to establish marketing and distribution alliances with third parties
to effect the distribution of LazerSmile(TM). These alliances could include
arrangements involving television shopping, specialty catalogs and traditional
distribution arrangements. While the Company has currently retained the services
of certain representatives to position and market its LazerSmile(TM) on a
television shopping network and in various mail order catalogs, there can be no
assurance that the Company will be successful in establishing these alliances.
See "Risk Factors - Uncertainty of Product and Market Acceptance". The Company
is also developing a fluid conditioning system, known as FlavorFlow(TM), that
sanitizes, flavors and administers fluids and enhances the scent of air present
during dental and medical procedures and a line of biomaterials for dental and
medical applications.

Recent Developments      
- -------------------
         
    
     On January 26, 1999, the Company entered into a distribution agreement with
Henry Schein, Inc. ("Schein"), a publicly-held distributor of healthcare
products and services to office-based dental and medical practitioners. The
distribution agreement grants to Schein the non-exclusive right to sell the
Company's Millennium(TM) HydroKinetic(TM) dental laser systems in the United
States. A purchase order for the first 20 systems has been issued by Schein, and
the Company shipped the first group of laser systems against that purchase order
in January 1999.     

     In December 1998, the Company added a diode laser system to its product 
line. The diode laser system is manufactured by an unaffiliated third party and
is a soft tissue laser intended for the dental market. There can be no assurance
that significant revenues will be realized in the future. See "Risk Factors -
Uncertainty of Product and Market Acceptance".    
    
     In November 1998, Jeffrey W. Jones became the President and Chief Executive
Officer and a member of the Board of Directors of the Company. Mr. Jones had 
served in various executive capacities including President and Chief Executive
Officer, since 1986 with HGM Medical Lasers and certain related entities, a Salt
Lake City-based manufacturer of medical lasers utilized in ophthalmologic,
dental and aesthetic applications. In January 1999, the Company retained Keith
G. Bateman to serve as its Vice President of Global Sales. Mr. Bateman held key
executive positions with HGM Medical Laser's international and domestic
divisions from 1994 through 1998, and previously spent several years in sales,
marketing and management in the computer industry. The Company added three
additional salespersons in January 1999 to focus on sales of its dental laser
products.    
    
     In December 1998, the Company's Board of Directors adopted a Stockholder 
Rights Plan (the "Plan"). The Plan provides that in the event any person becomes
the beneficial owner of 15% or more of the outstanding shares of the Company's 
Common Stock, each right (a "Right") (other than a Right held by the 15% 
stockholder and its associates) will be exercisable, on and after the close of 
business on the tenth business day following such event, to purchase the 
Company's Common Stock having a market value equal to two times the then current
exercise price of the Rights (initially $30.00). The Plan further provides that 
if, on or after the occurrence of such event, the Company is merged into any 
other corporation or 50% or more of the Company's assets or earning power are
sold, each Right (other than a Right held by the 15% stockholder and its
associates) will be exercisable to purchase common shares of the acquiring
corporation having a market value equal to two times the then current exercise
price of the Rights. The Rights expire on December 31, 2008 (unless previously
triggered) and are subject to redemption by the Board of Directors at $.001 per
right at any time prior to the first date upon which they become exercisable to
purchase shares of Common Stock. See "Risk Factors - Stockholders Rights Plan".

                                  RISK FACTORS

     THIS OFFERING INVOLVES SUBSTANTIAL INVESTMENT RISK, AND THE SHARES SHOULD
BE PURCHASED ONLY BY PERSONS WHO CAN AFFORD THE LOSS OF THEIR ENTIRE INVESTMENT.
IN EVALUATING AN INVESTMENT IN SHARES OF THE COMPANY, PROSPECTIVE INVESTORS
SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS, AMONG OTHERS, AS WELL AS
ALL OTHER INFORMATION SET FORTH HEREIN, INCLUDING THE EXHIBITS HERETO.  THE
FOLLOWING DISCUSSION OF RISK FACTORS IS NOT COMPREHENSIVE, AND EACH PROSPECTIVE
INVESTOR IS ADVISED TO MAKE ITS OWN ANALYSIS OF THE RISKS ASSOCIATED WITH AN
INVESTMENT IN THE SHARES.
    
     1. History of Net Losses; Future Profitability Uncertain. The Company
        -----------------------------------------------------             
reported net losses of $7,549,262, $3,050,333, $2,023,822, $2,463,259 and
$2,823,910 for the years ended December 31, 1993, 1994, 1995, 1996 and 1997,
respectively, and net losses of $1,958,843 and $8,699,923 for the nine months
ended September 30, 1997 and 1998, respectively. The Company had an accumulated
deficit of $36,823,262 at September 30, 1998. During the past five years, the
Company has not generated sufficient revenue to permit it to operate on a
profitable basis. The Company's ability to achieve profitable operations in the
future will depend in large part upon obtaining regulatory approvals for the
marketing of various products for certain applications and then successfully
bringing its products to market and generating sufficient revenue to produce a
net profit. The likelihood of long-term success of the Company must be
considered in light of the expenses, difficulties and delays frequently
encountered in the development and commercialization of new products and
competitive factors in the marketplace, as well as the burdensome regulatory
environment in which the Company operates. There can be no assurance that the
Company will ever achieve significant revenues or profitable operations.      
    
     2. Viability as Going Concern; Need for Additional Funding. The Company has
        -------------------------------------------------------                 
suffered recurring losses from operations and shows a need for continued funding
that raises substantial doubt about its ability to continue as a going concern.
The Company's ability to continue as a going concern is dependent upon its
ability to obtain outside financing through the issuance of either additional
shares of its Common or Preferred Stock or debt securities and, ultimately, upon
a movement to profitability through increased sales, product improvement through
engineering and cost containment. The Company's capital requirements depend on
numerous factors, including the progress of its research and development
programs, the progress of pre-clinical and clinical testing, the time and cost
involved in obtaining regulatory approvals, the cost of filing, prosecuting,
defending and enforcing patent claims and other intellectual property rights,
competing technological and market developments, demand for its products, and
payment terms it is able to negotiate with its suppliers and customers.      

                                       3
<PAGE>
 
    
     The Company currently is seeking additional capital resources to support
its working capital requirements. Should the Company not obtain such additional
capital sources during the next few months, it would be required to
substantially curtail its present growth plans. The Company has no commitment
with respect to any future financing. There can be no assurance that such
financing will be available or available on acceptable terms, or that such
financing would not result in a substantial dilution of stockholders' interests.
If adequate funds are not available, the Company's ability to meet its
obligations would be greatly impaired, and the Company may be unable to continue
operations. The Company's consolidated financial statements do not include any
adjustments that might result from the outcome of the uncertainty about the
Company's ability to continue as a going concern. The Company's financial
statements for the year ended December 31, 1997 were audited by the Company's
independent accountants, whose report includes an explanatory paragraph stating
that the financial statements have been prepared assuming the Company will
continue as a going concern and that the Company has recurring losses and shows
a need for continued funding that raise substantial doubt about its ability to
continue as a going concern.     
   
     3. Product Development; Risk of Defects. The development of new technology
        ------------------------------------
is a lengthy and capital intensive process and is subject to unforeseen risks,
delays, problems, and costs. The Company's success will in part depend upon its
ability to design, develop and introduce new products and enhancements on a
timely basis to meet changing customer needs, technological developments and
evolving industry standards. There can be no assurance that the Company will be
able successfully to develop any additional products, including products
currently under development, or enhance existing products. Unanticipated
technical or other problems may occur which could delay the Company's
development programs. Failure to complete development of key products could
result in the complete loss of the funds committed by the Company to such
products, which could be substantial. In addition, products as complex as the
Company's laser-based systems may contain latent defects which could from time
to time become apparent during commercial use. Remedying such defects could
require significant modifications at substantial costs to the Company.     
        
   
     4. Need to Establish Marketing Arrangements for Millennium. During 1997, 
        -------------------------------------------------------
one customer, Orbis Hi-Tech Dental GmbH, accounted for approximately two-thirds 
of the Company's net sales. Orbis Hi-Tech is the German distributor for the 
Millennium(TM) system, and in 1997, Germany was the principal market for that 
system.

     During 1998, the Company made no sales of Millennium(TM) systems to Orbis
Hi-Tech, while the Company was engaged in the redesign of the handpiece for the
Millennium(TM) system. During the fourth quarter of 1998, the Company received
FDA clearance to market the Millennium(TM) system in the United States for
certain hard tissue dental applications. Now that the handpiece redesign has
been completed and clearance has been obtained to market the Millennium(TM)
system in the United States, the Company will attempt to establish effective
marketing arrangements to generate revenue from the Millennium(TM) system in a
number of markets, including the United States. No assurances can be given that
the Company will be successful in establishing effective marketing arrangements
for Millennium(TM) in the United States or in other markets or that the Company
will generate significant revenue from the sale of Millennium(TM) systems.    
              
     5. Uncertainty of Product and Market Acceptance. The Company is only in the
        --------------------------------------------                            
initial phases of the marketing of its HydroKinetic(TM) tissue cutting system,
the Millennium(TM) system. Initial sales to a German distributor commenced
during the second quarter of 1997, and domestic sales commenced in November 1998
following dental hard tissue clearance from the FDA. In July 1997, the Company
received FDA clearance to market a laser system incorporating a variation of the
technology utilized in the Millennium(TM) for a broad range of dermatological
and general surgical soft tissue applications. In this variation, called
DermaLase(TM), the utilization of lower power laser pulses does not result in
the transformation of water droplets into mechanical cutting water particles,
but rather the air-water spray acts as a cooling agent. There can be no
assurance that the Millennium(TM) system, including the DermaLase(TM)
configuration, will receive market acceptance. Lasers have not been widely used
in certain medical and dental applications, and their effective use requires
training and experience. The acceptance of lasers may be adversely affected by
their high cost, concerns by patients and practitioners about their safety and
efficacy, and the substantial market acceptance and penetration of conventional
dental and medical tools. Current economic pressure may make dental and medical
practitioners reluctant to purchase substantial capital equipment or invest in
new technology. The failure of dental and medical lasers to achieve broad market
acceptance would have a material adverse effect on the Company's business,
financial condition and results of operations.     

     While the Company believes that the technology incorporated in its
Millennium(TM) surgical tissue cutting system should be effective in a broad
range of medical and dental applications, this belief (except with respect to
dental hard tissue and certain dermatological applications, for which clinical
research has been conducted) is based largely on preliminary in vitro and in
vivo research and extrapolation of observations in such clinical research. No
assurances can be given that the technology incorporated in its Millennium(TM)
surgical tissue cutting system will prove to be applicable to, or will find
market acceptance in, any medical or dental fields or that the Company will
receive clearance from the FDA or other regulatory agencies to market the
Millennium(TM) or any other laser-based system or other products embodying its
HydroKinetic(TM) technology in any additional jurisdictions or for any
additional applications. No assurances can be given that any other technologies
or products that the Company is developing will prove effective or will find
market acceptance.
   
     In August 1998, the Company introduced its first consumer product, the 
LazerSmile(TM) Tooth Whitening System, which utilizes a monochromatic optical 
energy light source embedded within a toothbrush in conjunction with a clear, 
non-abrasive tooth whitening gel. The Company has recognized a nominal amount of
revenue from sales of LazerSmile(TM) to date. The Company is currently selling 
LazerSmile(TM) over the Internet and through advertising in professional
journals, and is also attempting to establish marketing and distribution
alliances with third parties to effect the distribution of LazerSmile(TM). These
alliances could include arrangements involving television shopping, specialty
catalogs and traditional distribution arrangements. While the Company has
currently retained the services of certain representatives to position and
market its LazerSmile(TM) on a television shopping network and in various mail
order catalogs, there can be no assurance that the Company will be successful in
establishing these alliances, or that the LazerSmile(TM) will receive market
acceptance.     
   
     In December 1998, the Company added a diode laser system to its product
line. The diode laser system is manufactured by an unaffiliated third party and
is a soft tissue laser intended for the dental market. There can be no assurance
that the diode laser system will receive market acceptance or that significant
revenues will be realized in the future.     
   
     In the future, the Company may introduce additional products. There can be 
no assurance that any of these products will receive market acceptance or 
generate significant revenues.     

                                       4

     6. International Sales. In the years ended December 31, 1993, 1994, 1995,
        -------------------                                                   
1996 and 1997, approximately 30%, 57%, 70%, 47% and 73%, respectively, of the
Company's sales were export sales, of which approximately 100%, 85%, 72%, 80%
and 93%, respectively, were sales to Europe. To the extent that international
sales continue to make a substantial contribution to Company revenues, currency
fluctuations could make the Company's products less competitive in foreign
markets, contribute to fluctuations in the Company's operating results and, if
the Company makes sales denominated in foreign currencies or maintains
significant net assets or liabilities denominated in foreign currencies, expose
the Company to currency exchange valuation risks. Political instability, longer
receivable collection periods and difficulty in collecting accounts receivable
also pose risks to international sales. Moreover, the laws of certain countries,
or the enforcement thereof, may not protect the Company's products, intellectual
property rights or contractual rights to the same extent as the laws of the
United States. There can be no assurance that these factors will not have a
material adverse effect on the Company's business and financial condition and
results of operations.
   
     7. Product Liability Risk; Limited Insurance Coverage. The manufacture and
        --------------------------------------------------                     
sale of the Company's laser-based systems entail significant risk of product
liability claims in the event that the use of such systems is alleged to have
caused adverse effects on a patient. Although the Company has taken and will
continue to take what it believes are appropriate precautions, including
maintaining general liability and commercial liability insurance policies which
include coverage for product liability claims, there can be no assurance that
the Company's insurance coverage limits are or will be adequate to protect the
Company from any liabilities it might incur in connection with the sale of its
products. The Company currently maintains product liability insurance in the 
amount of $6,000,000 for any single event or $7,000,000 in the aggregate. In the
future, product liability insurance or such increased coverage as the Company
may desire may not be available on acceptable terms or on any basis whatsoever.
A product liability claim or series of claims successfully asserted against the
Company in excess of its insurance coverage could have a material adverse effect
on the Company's business and financial condition and results of operations.
Additionally, it is possible that adverse product liability actions could
negatively affect the Company's ability to obtain and maintain regulatory
approval for its products, as well as damage the Company's reputation in any or
all markets in which it participates.     
   
     8. Competition; Possible Technological Obsolescence. Development by others
        ------------------------------------------------                       
of new or improved products, processes, or technologies may make the Company's
products obsolete or less competitive. In the past, technological change has not
had a material impact on the Company. The ability of the Company to compete is
dependent on the Company's ability regularly to enhance and improve its products
and successfully develop and market new products. Many of the Company's
competitors have greater, and in some cases much greater, financial, managerial,
marketing, and technical resources than the Company. There can be no assurance
that the Company will successfully differentiate itself from its competitors,
that the market will consider the Company's products to be superior to its
competitors' products, that the Company's competitors will not develop new or
enhanced products that are more effective than the products which have been or
may be developed by the Company, or that the Company will be able to adapt to
evolving markets and technologies, develop new products, or achieve and, if
achieved, maintain technological advantages.     

     9. Patents and Proprietary Rights; Proprietary Technology. The Company
        ------------------------------------------------------             
relies, to a significant extent, on patents, trade secrets and confidentiality
agreements to protect its proprietary technology. There can be no assurance as
to the breadth or degree of protection which existing or future patents, if any,
may afford the Company, that such patents will not be circumvented or
invalidated, or that the Company's products do not and will not infringe on
patents or violate proprietary rights of others. If a patent infringement claim
is asserted against the Company, or if the Company is required to enforce its
rights under an issued patent, the cost of such actions may be very high,
whether or not the Company is successful. While the Company is unable to predict
what such costs would be if it is obligated to pursue patent litigation, its
ability to fund its operations and to pursue its business goals may be adversely
affected.

     10. Government Regulation. The Company's products are subject to
         ---------------------                                       
significant government regulation in the United States and other countries. To
test clinically, produce, and market products for human diagnostic and
therapeutic use, the Company must comply with mandatory procedures and safety
standards established by the FDA and comparable foreign regulatory agencies.
Typically, such standards require that products be approved by the government
agency as safe and effective for their intended use before being marketed for
human applications. The approval process is expensive and time-consuming, and no
assurance can be given that any agency will grant approval for the sale of the
Company's products for various dental and medical applications, or that the
length of time and the expenditures that the approval process will require will
not be extensive.

     The FDA also imposes requirements on manufacturers and sellers of products
under its jurisdiction, such as those relating to labeling, manufacturing
practices, record keeping, and reporting. The FDA also may mandate post-
marketing practices, including those relating to record keeping and reporting.
   
     The following table sets forth the status of FDA approval of the Company's 
principal products:     

<TABLE>    
<CAPTION> 
Product             Medical Application              Date Cleared    Status
- -------             -------------------              ------------    ------
<S>                 <C>                              <C>             <C> 
Millennium(TM)      Dental                           10/8/98         Cleared to market
DermaLase(TM)       Dermatology, General Surgery     7/18/97         Cleared to market
Elmer(TM)           Dental                           8/7/95          Cleared to market
LazerSmile(TM)      Tooth whitening                  N/A             Clearance not required
Canal Finder(TM)    Endodontic instrumentation       N/A             Clearance not required
FlavorFlow(TM)      Dental fluid conditioning        N/A            
</TABLE>     

     There can be no assurance that the appropriate approvals from the FDA will
be granted, that the process to obtain such approvals will not be expensive or
lengthy, or that the Company will have sufficient funds to pursue such
approvals. The failure to receive requisite approvals for certain of the
Company's products or processes, when and if developed, or significant delays in
obtaining such approvals, could prevent the Company from commercializing its
products as anticipated, and could have a material adverse effect on the
business of the Company.

     The Company is also subject to regulation under the Radiation Control for
Safety and Health Act administered by the Center for Devices and Radiological
Health ("CDRH") of the FDA. This law requires laser manufacturers to file new
product and annual reports, to maintain quality control, product testing, and
sales records, to incorporate certain design and operating features in lasers
sold to end-users, and to certify and label each laser sold to an end-user as
belonging to one of four classes, based on the level of 

                                       5
<PAGE>
 
radiation from the laser that is accessible to users. Various warning labels
must be affixed and certain protective devices installed, depending on the class
of the product. The CDRH is empowered to seek fines and other remedies for
violations of regulatory requirements.

     Various state dental boards are considering the adoption of restrictions on
the use of lasers by dental hygienists. In addition, dental boards in a number
of states are considering educational requirements regarding use of dental
lasers. While the scope of these restrictions and educational requirements is
not now known, they could have an adverse effect on sales of the Company's
laser-based products.
    
     The Company has not filed applications for regulatory approval with the
Japanese Ministry of Health and Welfare for any of its products, but is
performing clinical trials and gathering clinical data in preparation for said
application for the Millennium(TM) system.     

     The FDA and other governmental agencies, both in the United States and in
foreign countries, may adopt additional rules and regulations that may affect
the Company's ability to develop and market its products.
    
     11. Dependence on Suppliers. The Company purchases most of the components
         -----------------------                                              
included in its products from multiple suppliers; however, it does not maintain
long-term supply contracts with any of these suppliers. In addition, the Company
purchases the optical fiber used in the delivery system of its Millennium(TM)
system, including the DermaLase(TM) configuration, from a proprietary single
source. The disruption or termination of this source could have a material
adverse effect on the Company's ability to manufacture its Millennium(TM) system
and, consequently, on its business, financial condition and results of
operations.     
    
     12. Possible Volatility of Common Stock Price; Limited Public Market;
         -----------------------------------------------------------------
Compliance With Nasdaq Listing Requirements. The Company's Common Stock has been
- -------------------------------------------                                     
listed on The Nasdaq SmallCap Market since November 12, 1992, and the Company
has no present plans to apply to list the Common Stock on any other domestic
securities exchange. In April 1997, the Company's Common Stock was also listed
on the Berlin Stock Exchange under the symbol BLA. Trading in the Common
Stock has generally been sporadic since its listing on The Nasdaq SmallCap
Market, and there can be no assurance that an active trading market in the
Common Stock will be established or maintained.      

     The market prices for securities of emerging companies, including the
Company, have historically been highly volatile. Significant volatility in the
market price of shares of Common Stock may arise due to factors such as the
Company's developing business, historic losses and relatively low price per
share. In addition, future announcements concerning the Company or its
competitors may have a significant impact on the market price of the Common
Stock. Such announcements might include financial results, the results of
testing, technological innovations, new commercial products, changes to
government regulations, government decisions on commercialization of products,
developments concerning proprietary rights, litigation or public concern as to
safety of the Company's products. As long as there is only a limited public
market for the Common Stock, the sale of a significant number of shares of
Common Stock at any particular time could be difficult to achieve at the market
prices prevailing immediately before such shares are offered, and the offering
of a significant number of shares of Common Stock at one time could cause a
severe decline in the price of the Common Stock.
    
     For continued inclusion on The Nasdaq SmallCap Market, an issuer must
maintain (i) net tangible assets (total assets less the sum of total liabilities
and goodwill) of at least $2,000,000, (ii) net income of no less than $500,000
in the most recent fiscal year or in two of the three most recent fiscal years,
or (iii) market capitalization of at least $35,000,000, in addition to a minimum
bid price of $1 per share, a market value of the public float of at least
$1,000,000, a public float of at least 500,000 shares, at least two market
makers, and a minimum of 300 holders of 100 or more shares. At January 31, 1999,
the Company met all of the above criteria except for the alternative net income
criterion. If the Company continues to suffer significant losses from operations
without additional financing, it may not be able to meet the requirements for
the continued listing of Common Stock on The Nasdaq SmallCap Market, in which
case the Common Stock may be delisted from trading on The Nasdaq SmallCap
Market.     

     If the Common Stock were excluded from quotation and trading on The Nasdaq
SmallCap Market, it would likely trade on the over-the-counter market, in what
is commonly referred to as the "Electronic Bulletin Board" or "pink sheets".
Should that occur, holders of Common Stock may find it more difficult to dispose
of, or to obtain accurate quotations for the market price of, Common Stock. In
addition, if the Common Stock is not quoted on The Nasdaq SmallCap Market, it
may be subject to a rule that imposes restrictive sales practice requirements on
broker-dealers selling such securities to persons other than established
customers and accredited investors. For transactions covered by this rule, the
broker-dealer must, among other requirements, make a special suitability
determination regarding the purchaser and must receive the purchaser's written
consent to the transaction prior to any purchase. Consequently, the rule may
restrict the ability of broker-dealers to sell or limit the interest of broker-
dealers in selling Common Stock and may adversely affect the ability of holders
of Common Stock to sell shares. The exclusion of a security from continued
quotation on The Nasdaq SmallCap Market may also cause a decline in share price,
a diminution of news coverage of the Company, and greater difficulty in
arranging future financing.
    
     13. Reliance Upon Key Employees; Additional Personnel. The success of the
         -------------------------------------------------                    
Company is substantially dependent on the efforts of certain key personnel of
the Company: Jeffrey W. Jones, Ioana Riziou and Andrew Kimmel. The Company does
not presently have employment contracts with any of its key       

                                       6
<PAGE>
 
    
personnel, other than Jeffrey W. Jones. The loss of such key personnel could
adversely affect the Company's business and prospects. In such event, there can
be no assurance that the Company would be able to employ qualified replacements
on terms favorable to the Company.     
    
     The Company presently employs approximately 52 people. If and when the
scale of the Company's operations increases, the Company will be required to
increase the number of employees, including the number of management personnel.
No assurance can be given that the Company will be able to attract and retain
additional personnel, and particularly management personnel, having the 
capabilities that the Company will seek.      

     In seeking qualified personnel, the Company will be required to compete
with companies having greater financial and other resources than the Company
has. As some of its products are developed, the Company will have to attract
additional marketing, manufacturing, technical, scientific and administrative
personnel. Since the future success of the Company is, to a significant degree,
dependent upon its ability to attract and retain qualified personnel, the
Company's inability or failure to attract and retain such personnel could have a
materially adverse impact on the business of the Company.

     14. No Dividends on Common Stock. The Company has not paid any cash
         ----------------------------                                   
dividends on its Common Stock since its incorporation, and the Board of
Directors does not anticipate declaring any cash dividends on Common Stock in
the foreseeable future. The Company currently intends to utilize any earnings it
may achieve for reinvestment in its business. Future dividend policy will also
depend on the Company's earnings, capital requirements, financial condition,
debt covenants, and other factors considered relevant by the Company's Board of
Directors. It is unlikely that any dividends on Common Stock will be declared by
the Company in the foreseeable future.
    
     15. Possible Issuance of Additional Shares. The Company is authorized to
         --------------------------------------                              
issue 50,000,000 shares of Common Stock, of which 16,503,887 shares were issued
and outstanding as of January 31, 1999.  As of that date, 3,670,036 shares of
Common Stock had been reserved for future issuance upon exercise of outstanding
options and warrants, and an additional 618,399 shares have been reserved for
possible issuance pursuant to the Company's stock option and stock compensation
plans. Further, the Company has authorized 1,000,000 shares of preferred stock,
$.001 par value per share (the "Preferred Stock"), of which 100 shares had been
designated and issued as Series A 6% Redeemable Cumulative Convertible Preferred
Stock and 500,000 shares has been designated as Series B Junior Participating
Cumulative Preferred Stock, none of which is currently outstanding. The
Company's Board of Directors has authority to issue Preferred Stock in one or
more series and to fix the rights, privileges, restrictions and preferences
thereof. Accordingly, the Company may issue one or more series of Preferred
Stock in the future that will have preference over the Common Stock with respect
to the payment of dividends and upon its liquidation, dissolution, or winding up
or have voting or conversion rights which could adversely effect the voting
power and percentage ownership of the holders of the Common Stock. Although it
has no present commitments to do so (except as noted above), the Company is
currently seeking significant additional capital resources and may issue
additional shares of Common Stock, additional shares of Preferred Stock and
other securities in the future. Such issuances could have anti-takeover and
dilutive effects.     

     16. Impairment of Intangible Assets. During the fourth quarter of 1994, the
         -------------------------------                                        
Company recorded a charge of $959,000, representing a provision for the
impairment of the carrying value of its patents due to uncertainty regarding the
recoverability of such carrying value. The Company's 1994 evaluation included
consideration of such factors as the Company's failure by the fourth quarter of
1994 to achieve sufficient sales to permit profitable operations, extinguishment
of debt which had been issued to acquire certain patents, and the
underutilization of issued patents in various jurisdictions.  In the event the
expected net cash flows from other long-lived assets is less than the carrying
value of such assets, the Company could suffer additional impairment losses.

     17. Broad Discretion in Use of Proceeds.  As set forth in "Use of
         -----------------------------------                          
Proceeds", the net proceeds from the exercise of Warrants have not been
allocated to specific purposes, but rather will be applied to general working
capital, the refinement and improvement of existing products, and the
development of products currently under development and products the Company may
develop in the future.  Management will have considerable discretion in applying
such proceeds.
    
     18. Stockholder Rights Plan. The Company recently adopted a Stockholder 
         -----------------------
Rights Plan. The Plan provides that in the event any person becomes the 
beneficial owner of 15% or more of the outstanding shares of the Company's 
Common Stock, each right (a "Right") (other than a Right held by the 15% 
stockholder and its associates) will be exercisable, on and after the close of 
business on the tenth business day following such event, to purchase the  
Company's Common Stock having a market value equal to two times the then current
exercise price of the Rights (initially $30.00). The Plan further provides that 
if, on or after the occurrence of such event, the Company is merged into any 
other corporation or 50% or more of the Company's assets or earning power are 
sold, each Right (other than a Right held by the 15% stockholder and its 
associates) will be exercisable to purchase common shares of the acquiring 
corporation having a market value equal to two times the then current exercise
price of the Rights. The Rights expire on December 31, 2008 (unless previously
triggered) and are subject to redemption by the Board of Directors at $.001 per
right at any time prior to the first date upon which they become exercisable to
purchase shares of Common Stock. The Plan could make it more difficult for a
third party to acquire, or discourage a third party from acquiring, control of
the Company, and could also limit the price that some investors might be willing
to pay in the future for shares of the Company's Common Stock.     
    
     19. Year 2000 Issues. The Company is presently continuing its analysis of
         ----------------
its computer software and hardware requirements and anticipates capital
expenditures to increase significantly during 1999 in connection with the
acquisition of such software and hardware. Included among the software to be
purchased would be a new accounting system. That system, unlike the present
system, would be Year 2000 compliant. The Company's present software and
hardware is personal computer based and is unaltered from its original purchased
state except for those upgrades offered by the suppliers of such software. The
Company has received assurances from the suppliers of the software it employs,
other than the accounting system software, that such software is Year 2000
compliant. The Company intends to obtain certification that any computer
software and hardware purchased in 1999 is Year 2000 compliant. The Company does
not believe that its insistence upon Year 2000 compliant hardware or software
will materially increase the cost of any hardware or software acquired.      
   

     The Year 2000 problem arises out of the convention by which years have been
represented in computer programs by a two digit number representing the final
two digits in the year's designation and concern that time sensitive components
could fail or provide erroneous output if they do not correctly recognize years
beginning with 20 rather than 19.     
   
     The Company currently has limited information regarding the Year 2000
compliance status of its principal suppliers of goods and services and of its
principal customers.  The Company intends to initiate formal communications with
all such suppliers and customers with respect to the status of such persons'
computer systems in terms of Year 2000 compliance.  If any principal suppliers
lack systems that are Year 2000 compliant or programs that provide reasonable
assurance that such systems will be Year 2000 compliant well before the end of
1999, the Company will seek to establish relationships with alternate suppliers.
There is a single source supplier of optic fiber for the Millennium(TM) which
could not be easily replaced if it has non-compliant systems, and in the event
such supplier had a non-compliant system, the Company would attempt to establish
communications channels with such supplier that bypass the supplier's non-
compliant computer system. If any principal customers lack systems that are Year
2000 compliant or programs that provide reasonable assurance that such systems
will be Year 2000 compliant well before the end of 1999, the Company will
attempt to establish communications channels with such customers that bypass the
non-compliant computer systems. The Company believes that the costs associated
with monitoring Year 2000 compliance by suppliers and customers and dealing with
any non-compliance will not be material. The failure of the Company or any of
its principal suppliers and customers to become Year 2000 compliant in a timely
manner and the failure to establish alternate communications channels could have
a material adverse effect on the Company's business, financial condition,
results of operations and cash flow.     
        
    
     20. Forward-Looking Statements.  The forward looking statements contained
         --------------------------                                           
in this Prospectus are subject to various risks, uncertainties and other factors
that could cause actual results to differ materially from the results
anticipated in such forward looking statements. Included among the important
risks, uncertainties and other factors are those hereinafter discussed.      

     Few of the forward looking statements in this Prospectus deal with matters
that are within the unilateral control of the Company. There is substantial
government regulation of the manufacture and sale of medical products, including
many of the Company's products, by governmental agencies in both the United
States and foreign countries. These governmental agencies often have
considerable discretion in determining whether and when to approve the marketing
of the Company's products that have not yet received such approval.

     The availability of equity and debt financing to the Company is affected
by, among other things, domestic and world economic conditions and the
competition for funds. Rising interest rates might affect the feasibility of
debt financing that is offered. Potential investors and lenders will be
influenced by their evaluations of the Company and its products and comparisons
with alternative investment opportunities.

     The Company's products do not provide the exclusive means for accomplishing
an objective, and customers may choose alternative means. Many of the Company's
competitors have much greater financial resources and technical capabilities
than does the 

                                       7
<PAGE>
 
Company, which may enable such competitors to design and produce superior
products or to market their products in a manner that achieves commercial
success even in the face of technical superiority on the part of the Company's
products.

     The Company's patents may not offer effective protection against
competitors. Competitors may be able to design around the Company's patents or
employ technologies not covered by such patents. In addition, the Company's
patents may be challenged, and even if such patents are upheld, the diversion of
financial and human resources associated with patent litigation could adversely
affect the Company. The Company may be found to be violating the patents of
others and forced to obtain a license under such patents or modify the design of
its products.

     Rapid technological developments are expected to continue in the industries
in which the Company competes. The Company may not be able to develop,
manufacture and market products which meet changing user requirements or which
successfully anticipate or respond to technological changes on a cost-effective
and timely manner.

     While the Company believes that its technology incorporated into its
Millennium(TM) surgical tissue cutting system should be effective in a broad
range of medical and dental applications, this belief (except with respect to
dental hard tissue and certain dermatological applications, for which clinical
research has been and is being conducted) is based largely on preliminary in
vitro and in vivo research and extrapolation of observations in such clinical
research. No assurances can be given that the Company's Millennium(TM)
technology will prove to be applicable to, or will find market acceptance in,
any medical or dental fields or that the Company will receive clearance from the
FDA or other regulatory agencies to market the Millennium(TM) system or other
products embodying its HydroKinetic(TM) technology or variations thereof for any
additional applications or in any additional jurisdictions. See "Business - The
Millennium(TM) System."


                                USE OF PROCEEDS

     The Company will not receive any portion of the proceeds from the sale of
Common Stock to be sold in this Offering. The Company may receive net proceeds
of up to $3,815,000 from the exercise of the Warrants; management currently
anticipates that any such proceeds will be utilized for working capital and for
other general corporate purposes.

(1)  The number of shares beneficially owned by each stockholder is determined
     under rules promulgated by the Securities and Exchange Commission, and the
     information is not necessarily indicative of beneficial ownership for any
     other purpose. Under such rules, beneficial ownership includes any shares
     as to which the individual has sole or shared voting or investment power

     expressly disclaims beneficial ownership of the shares of Common Stock
     attributed to it in the above table; it does not have sole or shared power
     or ability to direct the vote of said shares, but does have shared power to
     dispose or direct the disposition of said shares.


                              PLAN OF DISTRIBUTION

     The shares of Common Stock subject to this Prospectus may be sold from time
to time by the Selling Stockholders or their successors, assigns or transferees
in private transactions for their own accounts. The Selling Stockholders may
offer and sell the shares from time to time in transactions on The Nasdaq
SmallCap Market on terms to be determined at the time of such sales. The Selling
Stockholders may also make private transfers directly or through a broker or
brokers. Alternatively, the Selling Stockholders may from time to time offer
shares of Common Stock offered hereby to or through underwriters, dealers or
agents, who may receive consideration in the form of discounts and commissions;
such compensation, which may be in excess of normal brokerage commissions, may
be paid by the Selling Stockholders and/or purchasers of the shares of Common
Stock offered hereby for whom such underwriters, dealers or agents may act. The
Selling Stockholders and any dealers or agents that participate in the
distribution of the shares of Common Stock offered hereby may be deemed to be
"underwriters" within the meaning of Section 2(11) of the Securities Act, and
any discounts, commissions or concessions received and any profit realized by
them on the resale of shares as principals may be deemed underwriting
compensation under the Securities Act. The aggregate proceeds to the Selling
Stockholders from sales of the Common Stock offered hereby will be the purchase
price of the Common Stock less any brokers' commissions. The Common Stock
offered hereby may be sold from time to time in one or more transactions at a
fixed price, which may be changed, or at varying prices determined at the time
of such sale or at negotiated prices.

     The Common Stock issuable upon exercise of the Warrants and offered hereby
will be issued by the Company in accordance with the respective terms thereof.

     The Company is contractually obligated to keep this Prospectus current for
as long a period as any Warrants remain outstanding and for two years
thereafter. The Company may from time to time notify the Selling Stockholders
that this Prospectus is not current and that sales of the Common Stock may not
occur until the Prospectus is supplemented by sticker or amendment, as
appropriate. To the extent required, the specific shares of Common Stock to be
sold, the names of the Selling Stockholders, the respective purchase prices and
public offering prices, the names of any agent, dealer or underwriter and any
applicable commissions 

                                       10
<PAGE>
 
or discounts with respect to a particular offer will be set forth in an
accompanying Prospectus supplement, or, if appropriate, a post-effective
amendment to the Registration Statement of which this Prospectus forms a part.

     The laws of certain states may require that sale of the shares of Common
Stock offered hereby be conducted solely through brokers or dealers registered
in those states. In addition, in certain states the shares of Common Stock
offered hereby may not be sold unless they have been registered or qualified for
sale in the applicable state or an exemption therefrom is available.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Common Stock offered hereby may not
simultaneously engage in market making activities with respect to the Common
Stock for a period of one business day prior to the commencement of such
distribution. In addition, without limiting the foregoing, the Selling
Stockholders will be subject to applicable provisions of the Exchange Act and
the rules and regulations thereunder including, without limitation, Regulation
M, which provisions may limit the timing of purchases and sales of Common Stock
by Selling Stockholders.

     The Company will pay substantially all the expenses incurred by the Selling
Stockholders and the Company incident to this Offering and the sale of the
Common Stock offered hereby to the public, but excluding any underwriting
discounts, commissions or transfer taxes. The expenses are estimated to be
approximately $20,000.

     The Company has agreed to indemnify the Selling Stockholders against
certain liabilities, including liabilities under the Securities Act.

                                 LEGAL MATTERS

     The validity of the Common Stock offered hereby has been passed upon for

Item 17.  Undertakings.
- -------   ------------ 

     The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement, to include any material
information with respect to the plan of distribution not previously disclosed in
the registration statement or any material change to such information in the
registration statement.

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

                                     II-1
<PAGE>
 
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Exchange Act) that is incorporated by reference in the registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     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 Certificate of Incorporation, the Delaware General
Corporation Law or otherwise, the Registration has been informed that in the
opinion of the commission such indemnification as against public policy as
expressed in the Act, and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the Registrant will,
unless in the opinion of its counsel the matter has already been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it against public policy as
expressed in the Act, and shall be governed by the final adjudication of such
issue.

     The undersigned Registrant hereby undertakes:

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

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

      WHEREAS, the Company and Executive desire to formalize the terms and

                                   ---------

      NOW, THEREFORE, in consideration of the foregoing premises, the terms and
conditions set forth herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto

     1.   Employment and Duties.
          --------------------- 

          (a)  The Company hereby employs Executive as its President and Chief
Executive Officer, and Executive accepts such employment.  In such 

                                      -1-
<PAGE>
 
capacity, Executive shall report and be responsible to the Company Board and
shall perform such duties and functions as may be assigned to Executive from
time to time by the Company Board. Executive shall comply with all proper
directives and instructions of the Company Board, as embodied in resolutions
adopted by the Company Board.

          (b)  Executive agrees during the term of his employment hereunder to
devote his entire business time and attention to the performance of his duties
hereunder and to serve the Company diligently and to the best of his ability.

      2.  Compensation.  For all services to be rendered by Executive hereunder,
          ------------                                                          
Executive shall be paid by the Company a base salary at the rate of Eighteen
Thousand Three Hundred Thirty-Three Dollars and Thirty-Three Cents ($18,333.33)
per month.  Executive's salary shall be paid on such basis as is the normal
payment pattern for executive officers of the Company but no less frequently
than monthly.

     In addition to the base salary payable under this Section 2(a), the Company
shall pay to Executive bonus or incentive compensation on the following basis:

          (a) For the period from the date of this Agreement through December
31, 1999, bonus compensation equal to ten percent (10%) of base salary for such
period, provided the consolidated revenue of the Company and its subsidiaries
for the year ending December 31, 1999, as reflected in the audited financial
statements of the Company for such year are no less than Twelve Million Dollars
($12,000,000).

          (b) For the balance of the term thereof, incentive compensation equal
to four percent (4%) of net income up to One Million Dollars ($1,000,000) and
two percent (2%) of net income in excess of One Million Dollars ($1,000,000),
computed in each case before provision for any federal, state and foreign taxes
based upon income and before provision for the incentive compensation payable to
Executive under this paragraph (b).  Such net income shall be as determined by
the firm of public accountants then serving as the Company's independent
auditors.

     3.      Options.  The Company Board has authorized the grant to Executive
             --------                                                         
of options to purchase up to 507,000 shares of BioLase Common Stock at an
exercise price equal to the fair market value (as determined in accordance with
the provisions of the Company's 1998 Stock Option Plan) of a share of Company
Common Stock on December 18, 1998.  The options will be embodied in stock option
agreements in the standard form employed or to be employed under the Company's
1998 Stock Option Plan, modified to be consistent with the terms of 

                                      -2-
<PAGE>
 
this Agreement, and will vest, and become exercisable with respect to increments
of the grant, in accordance with the following schedule:
 
              11,000 shares   on the last day of each calendar month during the
                              term hereof commencing December 31, 1998 and
                              continuing through December 31, 2001;

an additional 50,000 shares   at such time as the audited financial
                              statements for the Company for the year ending
                              December 31, 1999 are completed if such statements
                              reflect that the consolidated revenue of the
                              Company and its subsidiaries for such year equaled
                              or exceeded Twelve Million Dollars ($12,000,000);
                              and

an additional 50,000 shares   at such time through May 31, 2000 as the
                              closing price of Company Common Stock in the
                              principal market in which it then trades equals or
                              exceeds Eight Dollars ($8.00) per share for twenty
                              (20) consecutive trading days.

It is intended that such options shall be incentive stock options (within the
meaning of the Internal Revenue Code) to the maximum extent permitted by law.
Any options that do not qualify as incentive options shall be non-qualified
stock options.

     In the event Executive's employment with the Company is terminated by the
Company other than For Cause (as hereinafter defined), options shall continue to
vest for the longer of (a) the balance of the calendar year in which termination
occurs and (b) six months following termination.

     The Company will submit to its stockholders for their approval at the next
meeting of Company stockholders the plan pursuant to which such options are
being granted.

      4.  Benefits.  Executive shall be entitled to such fringe benefits and
          --------                                                          
perquisites as are generally made available to executive officers of the Company
from time to time.  In addition, Executive shall be entitled to four weeks of
paid vacation per annum, but unused vacation time may not be carried over from

       5.  Reimbursement of Expenses.  The Company shall reimburse Executive for
           -------------------------                                            
all reasonable business expenses incurred by Executive in connection with the
performance of his duties hereunder, provided that Executive furnishes to the
Company receipts and other documentation evidencing such expenditures.

          Until the arrangements contemplated by this paragraph are terminated
by written notice to Executive, the Company shall reimburse Executive (i) for
his reasonable travel expenses associated with travel between his present

  6.      Non-Competition.
          --------------- 

          (a)  Executive agrees during the term of his employment by the Company
not to compete with the Company or any of its Subsidiaries in any manner
whatsoever.  Without limiting the generality of the foregoing, Executive shall
not, during the term of his employment by the Company, directly or indirectly

capacity, own, manage, operate, join, control or participate in the ownership,
management, operation or control of or furnish any capital to or be connected in
any manner with or provide any services as a consultant for any business which
competes directly or indirectly with any of the businesses of the Company or any
of its Subsidiaries as they may be conducted from time to time; provided,
however, that nothing contained in this Agreement shall be deemed to preclude
Executive from owning not more than one-half of one percent (0.5%) of the
capital stock of a publicly-traded entity which is in competition with any of
such businesses.

          (b)  Executive may engage in civic, educational and charitable

<PAGE>
 
faith opinion of the Company Board, is in competition with the Company or a
Subsidiary. Executive shall be entitled to receive compensation from any
corporation with respect to which he serves as a director in accordance with
this Section 6(b). Notwithstanding anything to the contrary set forth herein,
Executive shall not be entitled to engage in any of the activities set forth in

performance of his duties and activities under this Agreement.

          (c)  Executive shall promptly disclose to the Company and shall use
his best efforts to transfer to or hold for the benefit of the Company but in no
event shall divert or exploit for his own personal profit or that of any other
person except the Company, any business opportunity or other opportunity to
acquire an interest in or a contractual relationship with any person or entity
where such person or entity is in the same line of business as the Company or a
Subsidiary or where such contractual relationship would be considered a feasible
and advantageous opportunity for the Company or a Subsidiary.

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

          (a)  The basic term of Executive's employment with the Company
hereunder shall commence on November 27, 1998 and, except in the event of
earlier termination, shall end on December 31, 2001.  Following December 31,
2001, the employment relationship under this Agreement shall continue on a

crime involving moral turpitude or any felony punishable by imprisonment in the
jurisdiction involved; (ii) the repeated failure by Executive to perform his
duties and functions hereunder in accordance with the instructions of the
Company Board as embodied in resolutions of the Company Board (provided that
such instructions do not require Executive to take any actions that are unlawful
or 

                                      -5-
<PAGE>
 
otherwise improper); (iii) the willful and material breach of this Agreement by
Executive if Executive fails to cure such breach within 15 business days
following written notice from the Company; or (iv) Executive's commission of any
act of fraud or dishonesty in connection with his employment by the Company.

Executive as severance pay and in lieu of any other salary or bonus payments
hereunder with respect to post-termination periods an amount equal to twelve
(12) times the base monthly salary Executive was receiving immediately prior to
the date of termination.  In the event the Company terminates the employment of
Executive subsequent to December 31, 2000 other than For Cause, the Company
shall pay to Executive as severance pay and in lieu of any other salary or bonus
payments hereunder with respect to post-termination periods an amount equal to
at least six (6) times the base monthly salary Executive was receiving
immediately prior to the date of termination, and in such case the sum of (i)
the number of months between the notice of termination and the date of
termination of employment and (ii) the number of months with respect to which
such severance pay is paid shall be no less than twelve (12).

     8.   Confidentiality.
          --------------- 

          (a)  The Company (which for purposes of this Section 8 shall mean the

and proprietary information and trade secrets about the businesses, operations
and prospects of the Company, including, without limitation, confidential and
proprietary information regarding the technology, finances, customers, suppliers
and employees of the Company, which constitute valuable business assets

without limitation:

            (i)   the identity and location of customers and suppliers;

                                      -6-
<PAGE>
 
            businesses and their respective relationships with their employees,
            suppliers and customers; and

          (iv)  files, reports, memoranda, computer software or programming and
budgets or other financial plans or information regarding the Company and its
business, properties or affairs.

          (b)  Executive agrees that he shall not, at any time subsequent to the

divulge or make known, directly or indirectly, to any person, or otherwise use
or exploit in any manner any Proprietary Information obtained by Executive at
any time during his employment by the Company, except in connection with and to
the extent required by his performance of his duties hereunder for the Company.
Executive agrees to advise the Company promptly of the identity and nature of
any contacts with any person or entity soliciting from Executive disclosure of
any Proprietary Information or soliciting Executive's involvement in any
business venture competitive with the Company.  Upon termination of this
Agreement, Executive shall deliver to the Company all tangible displays and
repositories of Proprietary Information, including without limitation customer
and supplier lists, files, records of research, proposals, reports, memoranda,
business methods and techniques, computer software and programming, budgets and
other financial plans and information, and other materials or records or
writings of any other type (including all copies thereof) made, used or obtained
by, or provided to, Executive, containing any Proprietary Information, whether
obtained prior to or subsequent to the execution of this Agreement.

     9.   Miscellaneous.
          ------------- 

          (a)  Executive represents and warrants to the Company that he is not
now under any obligation of a contractual or other nature to any person, firm or
corporation which is inconsistent or in conflict with this Agreement, or which
would prevent, limit or impair in any way the performance by him of his
obligations hereunder.

          (b)  The waiver by either party of a breach of any provision of this
Agreement must be in writing and shall not operate or be construed as a waiver

portion of this Agreement shall not affect the validity or enforceability of any

duties hereunder, except with the prior written consent of the Company.

          (g)  This Agreement is intended to and shall be governed by, and

California applicable to contracts executed in and wholly performed with such
state and without reference to any choice or conflict of laws principles.

          (h)  Any controversy, claim or dispute between the parties directly or
indirectly concerning this Agreement, or the breach or subject matter hereof,

Either party may demand an arbitration proceeding by providing the other party
and the American Arbitration Association with written notice thereof.  The
Company and Executive shall each select one arbitrator from a panel of at least
five (5) arbitrators (the "Arbitration Pool") obtained from the American
Arbitration Association within thirty (30) days of receiving the Arbitration
Pool list.  Such two arbitrators so selected shall agree on a third arbitrator
from the Arbitration Pool within fifteen (15) days thereafter.  In the event an
agreement has not been reached on the third arbitrator by the end of such
fifteen-day period, the third arbitrator shall be chosen by the American
Arbitration Association.

          The parties hereto agree that an action to compel arbitration pursuant
to this Agreement may be brought in any appropriate court, and in connection
therewith the laws of the State of California shall control.  Application may
also be made to any such court for confirmation of any decision or award of the
