             CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS      
    
     Certain statements incorporated by reference from documents filed with the
Commission by the Company and Ophthalmic Imaging Systems, a California
corporation ("OISI") in which the Company recently acquired approximately 51% of
the outstanding shares of common stock, are or may constitute forward-looking
statements. Such statements include those contained herein or therein regarding
the development or possible assumed future results of operations of the
Company's and OISI's businesses, the markets for the Company and OISI services
and products, anticipated capital expenditures, regulatory developments, any
statements preceded by, followed by or that include the words "believes,"
"expects," "anticipates," or similar expression, and other statements contained
or incorporated by reference herein regarding matters that are not historical
facts. Because such statements are subject to risks and uncertainties, actual
results may differ materially from those expressed or implied by such forward-
looking statements. The risks and uncertainties that may cause actual results to
differ include, among others, general economic conditions, risks associated with
acquisitions, dependence on suppliers, fluctuations in operating results because
of acquisitions, stock prices, changes in applicable federal, state and local
laws and regulations, alternate and emerging technologies, competition and
pricing pressures, overcapacity in the industry, seasonal fluctuations,
uncertainties of litigations, and risks associated with the operation, growth
and integration of newly acquired businesses. As a result of these factors, the
Company's revenue and income could vary significantly from quarter to quarter,
and past financial performance should not be considered a reliable indicator of
future performance. All subsequent written and oral forward-looking statements
attributable to the Company or persons acting on its behalf are expressly
qualified in their entirety by the cautionary statements set forth or referred
to above in this paragraph. Investors are cautioned not to place undue reliance
on such statements, which speak only as of the date hereof. The Company
undertakes no obligation to release publicly any revision to these forward-
looking statements to reflect events of or circumstances after the date hereof
or to reflect the occurrence of unanticipated events, except as may be required
by the federal securities laws.

                                  THE COMPANY

GENERAL

     The Company develops, manufactures and markets several lines of surgical
lasers, laser waveguides and laser fiber optic devices, disposables and
associated accessory products for the medical market.  The Company commenced
operations in August 1991 after acquiring substantially all of the assets of
Pfizer Laser Systems ("Pfizer Laser"), a division of Pfizer Hospital Products
Group, Inc. ("Pfizer HPG") which had entered the laser business in December
1984.  The assets acquired from Pfizer Laser by the Company included proprietary
rights to a broad base of laser and fiber optic technologies.
    
     The Company's recently acquired subsidiary Eyesys Technologies, Inc. is
engaged in the business of designing, developing and marketing noninvasive
corneal topography systems for use by ophthalmologists and optometrists in
surgical planning and evaluation, diagnosis of corneal pathologists and contact
lens fitting.      
    
     In addition, OISI, a corporation in which the Company has approximately a 
51% ownership interest, is engaged in the business of designing, developing, 
manufacturing and marketing digital imaging systems and image enhancement and 
analysis software for use by practitioners in the ocular health field.      

     The Company's product line of patented proprietary lasers includes CO\\2\\,
diode, argon, neodymium: yttrium aluminum garnet ("Nd:YAG"), erbium:yttrium
aluminum garnet ("Er:YAG") and holmium:yttrium aluminum garnet ("Ho:YAG")
lasers, which the Company believes are capable of a wide range of procedures in
multiple medical and surgical specialties ranging from cutting bone and teeth to
removing precise layers of cellular tissue in the eye. Representative procedures
for which the Company has market clearance from the United States Food and Drug
Administration ("FDA") include treatment of gum disease, laparoscopic
procedures, hard tissue and cavity preparation procedures, treatment of
endometriosis, dermatological treatment of port wine stains and discectomy. The
Company is currently conducting various clinical trials relating to additional
applications for its laser products. The primary focus of the Company's
research, marketing and sales efforts is in specific niche medical specialties,
such as dentistry and ophthalmology, where the Company believes opportunities
exist for clinical advances and market growth.

     The principal offices of the Company are located at 3 Morgan, Irvine,
California 92618, and its telephone number is (714) 859-0656.

     A description of the Company's business is set forth in the Company's
Annual Report on Form 10-K for the fiscal year ended March 31, 1997, as amended
(the "Annual Report"), which description is incorporated herein by this
reference.

                                  RISK FACTORS

     The securities offered hereby are highly speculative in nature and involve
a high degree of risk.  Prospective investors should carefully consider, along
with the other information contained in this Prospectus, the following
considerations and risks in evaluating an investment in the Company.
        
    
LIMITED OPERATING HISTORY; HISTORY OF OPERATING LOSSES     

   
     The Company was formed in July 1991 and has not generated significant
revenues to date. As of December 31, 1997, the Company had an accumulated
deficit of approximately $36.4 million and tangible net worth of approximately
$32 million. For the fiscal years ended March 31, 1995, 1996 and 1997, the
Company had operating losses of approximately $3.8 million, $5.8 million and
$5.6 million, respectively, resulting principally from costs incurred in
research and development and other costs of operations. For the fiscal quarter
ended December 31, 1997, the Company had operating profits of approximately
$227,441. There can be no assurance, however, that operating profits will
continue. The Company may incur losses for the foreseeable future due to the
significant costs associated with manufacturing, marketing and distributing its
laser products and due to continual research and development activities which
will be necessary to develop additional applications for the Company's laser
technology.     

   
     OISI has experienced operating losses for each fiscal year since its 
initial public offering in 1992 and has derived substantially all of its 
revenues from the sale of OISI digital imaging systems. While the management of 
OISI believes that the overall angiography market has modest growth potential, 
sustained growth in the angiography equipment business may become increasingly 
difficult due to increased competition. OISI's results of operations have 
historically fluctuated from quarter to quarter and management anticipates that 
such fluctuations will continue in the future. There can be no assurance that 
revenue growth or profitability can be achieved or sustained in the future.    

UNCERTAINTIES CONCERNING FUTURE PROFITABILITY

   
     The Company had operating profits for the first time in the fiscal quarter 
ended December 31, 1997. The Company's ability to maintain profitability will
depend, in part, on its ability to continue to successfully develop clinical
applications, obtain regulatory approvals for its products and develop the
capacity to manufacture and market such products on a wide scale. There is no
assurance that the Company will be able to successfully make the transition from
research and development to manufacturing and selling commercial medical laser
products on a broad basis. While attempting to make this transition, the Company
will be subject to all risks inherent in a growing venture, including the need
to produce reliable products, develop marketing expertise and enlarge its sales
force.    

UNCERTAIN MARKET ACCEPTANCE

     The Company's future sales are dependent, in part, on the Company's ability
to demonstrate to dentists, ophthalmologists and other physicians the potential
cost and performance advantages of its laser systems over traditional methods of
treatment and, to a lesser extent, over competitive laser systems.  To date,
commercial sales of the Company's lasers have been limited, and no assurance can
be given that these laser products can be successfully commercialized on a broad
basis.  Lasers have not been widely used in dentistry and their use requires
training and expertise.  The acceptance of dental lasers may be adversely
affected by their high cost, concerns by patients and dentists relating to their
safety and efficacy, and the substantial market acceptance and penetration of
alternative dental tools such as the dental drill.  Current economic pressure
may make doctors and dentists reluctant to purchase substantial capital
equipment or invest in new technology.  The failure of medical lasers to achieve
broad market acceptance would have a material adverse effect on the Company's
business, financial condition and results of operations.  No assurance can be
given that any of the Company's products will be accepted by the medical or
dental community or by patients, or that a significant market for the Company's
laser systems will be developed and sustained.  The Company currently has a
limited sales force and will need to hire additional sales and marketing
personnel to increase the general acceptance of its products.

COSTS ASSOCIATED WITH INTEGRATION OF ACQUIRED BUSINESSES    

   
     On September 30, 1997, the Company acquired EyeSys Technologies, Inc.
("EyeSys") through the merger of a newly formed subsidiary of the Company with
and into EyeSys (the "Merger"). Upon the effectiveness of the Merger, EysSys
became a wholly-owned subsidiary of the Company. As a result of the Merger, the
Company must integrate and coordinate the business formerly operated by EyeSys
with the Company's other businesses. Although the Company believes that there
are certain synergies in the two lines of business, it may incur expenses in
connection with its efforts to integrate the two businesses. For example,
although certain of the existing EyeSys management personnel have been retained
by EyeSys following the Merger, members of the Company's management must also
expend time and effort on new activities relating to the EyeSys operations,
which will detract from their time available to attend to the Company's pre-
Merger activities. No assurance can be given that the Company will receive the
advantages from the Merger, or that the expenses or dislocations it may suffer
or incur as a result of the post-Merger coordination of these businesses will
not be material.    

     EyeSys currently markets two primary products (a portable and a stationary
corneal topography measuring system) in a highly competitive market.
Historically, EyeSys has incurred substantial losses. The ability of EyeSys to
achieve a break even level of operating performance is dependent on the demand
for its products as well as maintaining sufficient research, development and
sales and marketing expenditures to meet the requirements of the market. There
can be no assurance that the revenues from the EyeSys product line will be
sufficient to cover all of the expenses related to such operations.

   
     In the event that the Company's Offer (defined below) to acquire additional
outstanding shares of OISI is accepted, the Company will encounter issues
similar to the above regarding the integration of the two businesses. As a
result, certain expenses may be incurred in efforts to address such issues.    

   
ABILITY TO EXERT SIGNIFICANT INFLUENCE    

   
     The Company recently made an offer (the "Offer") to acquire the remaining
outstanding shares of common stock of OISI from its shareholders.  As of the
date of the Offer, the Company owned beneficially approximately 51% of the
outstanding common stock of OISI.  If the Offer is successful, the Company will
beneficially own an increased percentage of OISI's outstanding common stock.  As
a result, even if the Offer is unsuccessful, the Company will control all
outcomes submitted to a vote of OISI's shareholders, including the election of
directors and significant corporate transactions.    

   
PURCHASE METHOD OF ACCOUNTING MAY IMPACT OPERATING RESULTS    

   
     Under the purchase method of accounting, the estimated fair value of the
OISI common stock purchased under the Offer would be recorded as the cost of
acquiring OISI's business.  This cost would be allocated to the individual
assets acquired and liabilities assumed according to their respective fair value
with the excess of the estimated fair value of OISI common stock over the fair
value of net assets acquired recorded as goodwill, to be amortized over a period
up to 40 years.  The estimated fair value of the OISI common stock to be
purchased under the Offer is substantially in excess of the amount which the net
assets are carried in OISI's accounts.  Therefore, purchase method accounting
treatment may have a material adverse impact on the reported operating results
of the combined companies.    
   
REALIZATION OF EXPECTED OPERATING SYNERGIES MAY NOT MATERIALIZE    

   
     The consummation of the Offer will involve the combination of two
companies that have previously operated independently.  Although the Company
expects to achieve savings in operating costs, delays or unexpected expenses
related to operating the companies under common ownership could result in a
reduction in net income.    

GOING CONCERN REPORT WITH RESPECT TO EYESYS

   
     EyeSys' independent auditors have included an explanatory paragraph in
their report covering EyeSys' financial statements for the year ended December
31, 1996, which paragraph emphasizes substantial doubt as to EyeSys' ability to
continue as a going concern. EyeSys' independent auditors cited the following 
reasons for such explanatory paragraph: (i) EyeSys has reported net losses of 
$4,164,998, $3,424,996 and $3,708,657 for the years ended December 31, 1996, 
1995 and 1994, respectively, (ii) EyeSys was in default of several loan 
covenants relating to its revolving lines of credit, and (iii) EyeSys had not 
repaid such loan obligations within their respective terms.    

DEPENDENCE ON SUPPLIERS

     The Company purchases certain raw materials, components and subassemblies
included in the Company's products from a limited group of qualified suppliers
and does not maintain long-term supply contracts with any of its key suppliers.
The disruption or termination of these sources could have a material adverse
effect on the Company's business and results of operations.  For example, during
fiscal 1994, the Company's sole supplier of the specialized optic fiber required
for use in the Company's Er:YAG lasers ceased to provide this fiber to the
Company.  While the Company has since qualified the new suppliers of this fiber,
the Company's inability to obtain sufficient quantities of this specialized

                                      -7-
<PAGE>
 
optical fiber had a material adverse effect on the volume of Er:YAG lasers the
Company was able to sell during fiscal 1994 and 1995.  While the Company
believes that alternative suppliers could be found, there can be no assurance
that any supplier could be replaced in a timely manner.  Any interruption in the
supply of other key components could have a material adverse effect on the
Company's ability to manufacture its products and on its business, financial
condition and results of operations.

     Certain computer memory chips used by EyeSys in its proprietary hardware
are manufactured by a single company. These computer memory chips are subject to
rapid innovation and obsolescence. The discontinuance of the manufacturing of
this chip may require EyeSys to redesign certain hardware and software to
accommodate a replacement chip. While in the past EyeSys has been successful in
these redesign efforts, there can be no assurance that such an event would not
prove costly or cause a disruption in sales of corneal topography systems.

RISKS APPLICABLE TO FOREIGN SALES

     Sales of the Company's products to foreign markets account for a
substantial portion of the Company's sales.  Foreign sales expose the Company to
certain risks, including the difficulty and expense of maintaining foreign sales
distribution channels, barriers to trade, potential fluctuations in foreign
currency exchange rates, political and economic instability, availability of
suitable export financing, accounts receivable collections, tariff regulations,
quotas, shipping delays, foreign taxes, export licensing requirements and other
United States and foreign regulations that may apply to the export of medical
lasers.  The regulation of medical devices worldwide also continues to develop,
and there can be no assurance that new laws or regulations will not have an
adverse effect on the Company.  In addition, the Company may experience
additional difficulties in providing prompt and cost effective service of its
medical lasers in foreign countries.  The Company does not carry insurance
against such risks.  The occurrence of any one or more of these events may
individually or in the aggregate have a material adverse effect upon the
Company's business, financial condition and results of operations.

RISK OF TECHNOLOGICAL OBSOLESCENCE

     The markets in which the Company's laser products compete are subject to
rapid technological change as well as the potential development of alternative
surgical techniques or new pharmaceutical products.  Such changes could render
the Company's products uncompetitive or obsolete.  The Company will be required
to invest in research and development to attempt to maintain and enhance its
existing products and develop new products.  No assurances can be given that
such research and development efforts will result in the introduction of new
products or product improvements.

DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY

     The Company's success will depend in part on its ability to obtain patent
protection for products and processes, to preserve its trade secrets and to
operate without infringing the proprietary rights of third parties.  While the
Company holds 23 U.S. patents and 16 foreign patents (including 2 utility model
patents) and has other patent applications pending in the United States and
foreign countries, no assurance can be given that any additional patents will be
issued, that the scope of any patent protection will exclude competitors or that
any of the Company's patents will be held valid if subsequently challenged.
Further, there can be no assurance that others will not independently develop
similar products, duplicate the Company's products or design products that
circumvent any patents used by the Company.  The Company is aware of certain
patents which, along with other patents that may exist or be granted in the
future, could restrict the Company's right to market certain of its technologies
without a license, including, without limitation, patents relating to the
Company's lens emulsification product and ophthalmic probes

                                      -8-
<PAGE>
 
    
for the Er:YAG laser. In the past, the Company has received allegations that
certain of the Company's laser products infringe other patents. BriteSmile,
Inc., a wholly-owned subsidiary of Ion Laser Technology, Inc. has alleged that
the use of one of the Company's products in connection with a laser bleaching
procedure infringes a patent which they hold. There has been significant patent
litigation in the medical industry in general, and in the medical laser industry
in particular. Adverse determinations in litigation or other patent proceedings
to which the Company may become a party could subject the Company to significant
legal judgments or other liabilities to third parties and could require the
Company to seek licenses from third parties that may or may not be economically
viable. Patent and other intellectual property rights disputes often are settled
through licensing arrangements. No assurance can be given that any licenses
required under these or any other patents or proprietary rights would be
available on terms acceptable to the Company, if at all. If the Company does not
obtain such licenses, it could encounter delays in product introductions while
it attempts to design around such patents, or it could find that the
development, manufacture or sale of products requiring such licenses could be
enjoined. If the Company is found, in a legal proceeding, to have infringed the
patents or other proprietary rights of others, it could be liable for
significant damages. The Company also relies upon unpatented trade secrets, and
no assurance can be given that others will not independently develop or
otherwise acquire substantially equivalent trade secrets. In addition, at each
balance sheet date, the Company is required to review the value of its
intangible assets based on various factors, such as changes in technology. Any
adjustment downward in such value may result in a write-off of the intangible
asset and a substantial charge to earnings, thereby adversely affecting the
operating results of the Company in the future.    

NEED FOR FDA AND FOREIGN GOVERNMENTAL APPROVALS; GOVERNMENT REGULATION

     The Company's products are regulated as medical devices by the FDA under
the Federal Food, Drug and Cosmetic Act (the "FDC Act").  As such, these devices
require either Section 510(k) premarket clearance ("510(k)") or approval of a
premarket approval application ("PMA") by the FDA prior to commercialization.
Satisfaction of applicable regulatory requirements may take several years and
varies substantially based upon the type, complexity and novelty of such
devices, as well as the clinical procedure.  Filings and governmental approvals
may be required in foreign countries before the devices can be marketed in these
countries.  There is no assurance that further clinical trials of the Company's
medical lasers or of any future products will be successfully completed or, if
they are completed, that any requisite FDA or foreign governmental approvals
will be obtained.  FDA or other governmental approvals of products developed by
the Company in the future may require substantial filing fees which could limit
the number of applications sought by the Company and may entail limitations on
the indicated uses for which such products may be marketed.  In addition,
approved or cleared products may be subject to additional testing and
surveillance programs required by the FDA and other regulatory agencies, and
product approvals and clearances could be withdrawn for failure to comply with
regulatory standards or by the occurrence of unforeseen problems following
initial marketing.  Also, the Company has made modifications to certain of its
existing products which it does not believe require the submission of a new
510(k) notification to the FDA.  However, there can be no assurance that the FDA
would agree with the Company's determination and not require the Company to
discontinue marketing one or more of the modified devices until they have been
cleared by the FDA.  The Company is also required to adhere to applicable
requirements for current Good Manufacturing Practices ("CGMP") and radiological
health requirements, to engage in extensive record keeping and reporting and to
comply with the FDA's product labeling, promotional and advertising
requirements.  Noncompliance with state, local, federal or foreign requirements
can result in fines, injunctions, civil penalties, recall or seizure of
products, total or partial suspension of production, delay, denial or withdrawal
of premarket clearance or approval of devices, recommendations by the FDA that
the Company not be allowed to enter into government contracts, and criminal
prosecution, all of which would have a material adverse effect on the Company's
business, financial condition and results of operations.  The Company's
manufacturing facilities are subject to

                                      -9-
<PAGE>
 
periodic inspections by state and federal agencies, including the FDA, the
California Department of Health Services, and comparable agencies in other
countries.

DEPENDENCE ON KEY PERSONNEL

   
     The Company depends to a considerable degree on a limited number of key
personnel, including Colette Cozean, Ph.D., its Chairman of the Board,
President, Chief Executive Officer and Director of Research.  Dr. Cozean is also
an inventor of a number of the Company's patented technologies. During the
Company's limited operating history, many key responsibilities within the
Company have been assigned to a relatively small number of individuals.  The
loss of Dr. Cozean's services or those of certain other members of management
could adversely affect the Company. The Company carries key person life
insurance in excess of $3 million on Dr. Cozean. The Company has no employment
agreements with its key personnel. The success of the Company will also depend,
among other factors, on the successful recruitment and retention of qualified
technical and other personnel.    

HIGHLY COMPETITIVE INDUSTRY

     The medical laser industry is subject to intense competition and is
characterized by rapid technological change.  The Company is and will continue
to be subject to competition in its targeted markets, principally from
businesses providing other traditional surgical and nonsurgical treatments,
including existing and developing technologies, and to a lesser extent
competitors' CO\\2\\, Argon, Er:YAG and Nd:YAG lasers.  Many of the Company's
competitors have substantially greater financial, marketing and manufacturing
resources and experience than the Company.  Furthermore, the Company expects
other companies will enter the market, particularly as medical lasers gain
increasing market acceptance.  Significant competitive factors which will affect
future sales in the marketplace include regulatory approvals, performance,
pricing and general market acceptance.

     The corneal topography market is also highly competitive. There are many
companies, both public and private, some with significantly greater resources
than EyeSys, engaged in the corneal topography market. These companies include
Alcon Laboratories (a subsidiary of Nestle), Humphrey Instruments (a subsidiary
of Carl Zeiss), and Tomey Technology. These companies, together with EyeSys and
others, market corneal topography instruments which utilize a technology for
measuring corneal curvature based on reflected images. Other companies,
including PAR Technology and Orbtek, utilize other technologies to measure the
corneal surface. There can be no assurances that EyeSys' competitors will not
succeed in developing technologies, procedures or products that are more
effective or economical than those marketed or being developed by EyeSys or that
would render EyeSys' products obsolete or noncompetitive.

     To continue to remain competitive, EyeSys must develop new software and
hardware meeting the needs of ophthalmologists and optometrists.  EyeSys' future
revenues will depend, in part, on its ability to develop and commercialize these
new products as well as on the success of development and commercialization
efforts of its competitors.
   
     The industry in which OISI competes, development and sale of ocular imaging
systems, is also highly competitive.  OISI's two major competitors are Topcon 
and Tomey, as well as a variety of smaller companies in international markets.  
Many of these competitors have greater financial, marketing and manufacturing 
resources and experience than OISI.  There can be no assurance that OISI's 
competitors will not succeed in developing technologies, procedures or products 
that are more effective or economical than those marketed or being developed by 
OISI or that would render OISI's products obsolete or noncompetitive.     

POTENTIAL FLUCTUATIONS IN QUARTERLY OPERATING RESULTS

     Due to the relatively high sales price of the Company's laser systems and
the low sales unit volume, minor timing differences in receipt of customer
orders have produced and could continue to produce significant fluctuations in
quarterly results.  In addition, if anticipated sales and shipments in any
quarter do not occur when expected, expenditures and inventory levels could be
disproportionately high, and the Company's operating results for that quarter,
and potentially for future quarters, would be

                                     -10-
<PAGE>
 
adversely affected.  Quarterly results may also fluctuate based on a variety of
other factors such as seasonality, production delays, product mix, cancellation
or rescheduling of orders, new product announcements by competitors, receipt of
FDA clearances or approvals by the Company or its competitors, notices of
product suspension or recall, the Company's ability to manage product
transitions, sales prices and market conditions.  In addition, if the Company
expands or augments its manufacturing capabilities in connection with the
introduction of new products, quarterly revenues and operating results are
expected to fluctuate to an even greater degree.

UNCERTAIN ABILITY TO MEET CAPITAL NEEDS

     The Company will require substantial additional funds for its research and
development programs, preclinical and clinical testing, development of its sales
and distribution force, operating expenses, regulatory processes and
manufacturing and marketing programs.  The Company's capital requirements will
depend on numerous factors, including the progress of its research and
development programs, results of preclinical and clinical testing, the time and
cost involved in obtaining regulatory approvals, the cost of filing,
prosecuting, defending and enforcing any patent claims and other intellectual
property rights, competing technological and market developments, developments
and changes in the Company's existing research, licensing and other
relationships and the terms of any new collaborative, licensing and other
arrangements that the Company may establish.  The Company believes its available
current assets and investment income will be sufficient to meet its operating
expenses and capital expenditures through the next 12 months.  However, the
Company's cash requirements may vary materially from those now planned due to
potential future acquisitions, the progress of research and development
programs, results of clinical testing, relationships with strategic partners, if
any, competitive and technological advances, the FDA and foreign regulatory
processes and other factors.  There can be no assurance, however, that
additional financing will be available when needed, or if available, will be
available on acceptable terms.  Insufficient funds may prevent the Company from
implementing its business strategy or may require the Company to delay, scale
back or eliminate certain of its research and product development programs or to
license to third parties rights to commercialize products or technologies that
the Company would otherwise seek to develop itself.

POSSIBLE VOLATILITY OF STOCK PRICE

     The stock market has from time to time experienced significant price and
volume fluctuations that are unrelated to the operating performance of
particular companies.  These broad market fluctuations may adversely affect the
market price of the Securities.  In addition, the market price of the Securities
has been and is likely to be highly volatile.  Factors such as
fluctuations in the Company's operating results, announcements of technological
innovations or new products by the Company or its competitors, FDA and
international regulatory actions, developments with respect to patents or
proprietary rights, public concern as to the safety of products developed by the
Company or its competitors, changes in health care policy in the United States
and internationally, changes in analysts' recommendations regarding the Company,
other medical companies or the medical laser industry generally and general
market conditions may have a significant effect on the market price of the
Securities.

PRODUCT LIABILITY EXPOSURE

     The sale of the Company's laser systems and corneal topography systems
involves the inherent risk of product liability claims against the Company. The
Company currently maintains product liability insurance coverage in the

                                     -11-
<PAGE>
 
amount of $5 million per occurrence and $5 million in the aggregate, but such
insurance is expensive, subject to various coverage exclusions and may not be
obtainable by the Company in the future on terms acceptable to the Company.
There can be no assurance that claims against the Company arising with respect
to its products will be successfully defended or that the insurance carried by
the Company will be sufficient to cover liabilities arising from such claims.  A
successful claim against the Company in excess of the Company's insurance
coverage could have a material adverse effect on the Company.

LIMITATIONS ON THIRD PARTY REIMBURSEMENT
   
     The Company's products are generally purchased by physicians,
opthamologists, dentists and surgical centers which then bill various third
party payors, such as government programs and private insurance plans, for the
procedures conducted with these products. Third-party payors carefully review
and are increasingly challenging the prices charged for medical products and
services. Reimbursement rates from private companies vary depending on the
procedure performed, the third-party payor, the insurance plan and other
factors. Medicare reimburses hospitals a prospectively-determined fixed amount
for the costs associated with an in-patient hospitalization based on the
patient's discharge diagnosis, and reimburses physicians a prospectively-
determined fixed amount based on the procedure performed, regardless of the
actual costs incurred by the hospital or physician in furnishing the care and
unrelated to the specific devices used in that procedure. Third-party payors are
increasingly scrutinizing whether to cover new products and the level of
reimbursement for covered products. While the Company believes that the laser
procedures using its products have generally been reimbursed, payors may deny
coverage and reimbursement for the Company's products if they determine that the
device was not reasonable and necessary for the purpose for which used, was
investigational or not cost-effective. As a result, there can be no assurance
that reimbursement from third party payors for these procedures will be
available or if available, that reimbursement will not be limited, thereby
adversely affecting the Company's ability to sell its products on a profitable
basis. Moreover, the Company is unable to predict what legislation or
regulation, if any, relating to the health care industry or third-party coverage
and reimbursement may be enacted in the future, or what effect such legislature
or regulation may have on the Company.     

UNCERTAINTIES REGARDING HEALTH CARE REFORM

     Several states and the United States government are investigating a variety
of alternatives to reform the health care delivery system and further reduce and
control health care spending.  These reform efforts include proposals to limit
spending on health care items and services, limit coverage for new technology
and limit or control the price health care providers and drug and device
manufacturers may charge for their services and products.  If adopted and
implemented, such reforms could have a material adverse effect on the Company's
business, financial condition and results of operations.

CHARGE TO EARNINGS IN THE EVENT OF RELEASE OF ESCROW SHARES

     The Company has outstanding shares of Class E-1 and Class E-2 Common Stock
(the "Escrow Shares") which are being held by the Company in escrow, and which
will be released from escrow and converted into shares of Common Stock if
certain criteria are met.  In the event any of these criteria are met and any
shares are released from escrow to stockholders who are officers, directors,
employees or consultants of the Company, a substantial noncash compensation
expense will be recorded for financial reporting purposes.  The recognition of
such compensation expense may have an adverse effect on the market price of the
Company's securities.

                                     -12-
<PAGE>
 
SHARES ELIGIBLE FOR FUTURE SALE; EFFECT OF OUTSTANDING OPTIONS AND WARRANTS
   
     Sales of a substantial number of shares of Common Stock in the public
market could adversely affect the market price for the Common Stock.
Substantially all of the Company's shares of Common Stock outstanding as of the
date hereof are freely tradeable, subject to compliance with Rule 144
promulgated under the Securities Act. As of March 10, 1998, an additional
approximately 7,592,460 shares of Common Stock are issuable upon the 
exercise of the Company's outstanding Class B Warrants ("Class B Warrants"), and
in excess of five million shares of Common Stock are issuable upon exercise of
other outstanding warrants and options. The issuance of shares upon the exercise
of the Class B Warrants has been registered under the Securities Act, and
substantially all of the shares of Common Stock issuable upon exercise of the
remaining options and warrants may be resold pursuant to currently effective
registration statements or Rule 701 under the Securities Act. The existence of
the Company's outstanding warrants and options could adversely affect the
Company's ability to obtain future financing. The price which the Company may
receive for the Common Stock issued upon exercise of such options and warrants
will likely be less than the market price of the Common Stock at the time such
options and warrants are exercised. Moreover, the holders of the options and
warrants might be expected to exercise them 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 for by the options and
warrants.     

POTENTIAL ANTI-TAKEOVER EFFECTS OF PREFERRED STOCK

     The Company's Articles of Incorporation authorize the issuance of 8,850,000
shares of "blank check" preferred stock, which will have such designations,
rights and preferences as may be determined from time to time by the Board of
Directors.  Accordingly, the Board of Directors is empowered, without
stockholder approval, to issue preferred stock with dividend, liquidation,
conversion, voting or other rights which could adversely affect the voting power
or other rights of the holders of the Common Stock.  In the event of such
issuance, the preferred stock could be utilized, under certain circumstances, as
a method of discouraging, delaying or preventing a change in control of the
Company.

                                     -13-
<PAGE>
 
                                USE OF PROCEEDS

   
       Holders of Warrants are not obligated to exercise their Warrants and 
there can be no assurance that any such holder will choose to exercise all or
any of his Warrants. In the event that all of the outstanding Warrants are
exercised, the gross proceeds to the Company would be $6,994,315.    

       The Company intends to use the proceeds received upon the exercise of the
Warrants, if any, for general corporate purposes and working capital to support 
anticipated growth, including research and development programs and continuing 
development of a distributor network.  The Company may also use a portion of the
net proceeds received upon exercise of the Warrants for possible acquisitions of
complementary businesses, products and technologies.

                              RECENT DEVELOPMENTS

   
     The Company recently entered into a Stock Purchase Agreement (the "Stock
Purchase Agreement") with OISI pursuant to which the Company agreed to make an
Offer to all of OISI's shareholders with a view to acquiring OISI and OISI
agreed to recommend the Company's Offer and not to solicit any other acquisition
proposals.    

   
     Concurrently with the execution of such Stock Purchase Agreement, the
Company entered into individual purchase agreements with certain OISI
shareholders enabling the Company to acquire a total of 2,131,758 shares of OISI
common stock constituting approximately 51.3% of the total outstanding common
stock of the Company as of February 26, 1998. In exchange for the OISI shares,
the Company paid an aggregate consideration of $2,137,184.80 consisting of a
combination of cash and certain warrants. Pursuant to the Stock Purchase
Agreement, the Company has agreed to pay $1.75 in cash plus stock and warrants
for each additional share of OISI common stock acquired. The estimated aggregate
value of the consideration to be paid for each share of OISI common stock is
$2.18.     

       
     In addition, the Company recently completed the redemption of all of its 
outstanding publicly traded Class A Warrants. In connection with such 
redemption, 2,200,043 or approximately 99% of the outstanding Class A Warrants 
were exercised by the holders thereof and an aggregate of $14,300,279 was 
received by the Company. This total includes the proceeds from the exercise of 
warrants associated with unit purchase options granted in connection with prior 
offerings and exercised during the warrant call period.

     In January 1998, the Board of Directors appointed Judy McCall to the office
of Vice President--Human Resources Administration and Special Projects. Ms.
McCall joined the Company in 1993 and since that time has served as Director of
Human Resources Administration and Special Projects.

     In February 1998, Randy Alexander joined the Company as Executive Vice 
President--Sales, Marketing and Business Units.  Prior to joining the Company, 
Mr. Alexander served as Senior Vice President for Asian Pacific, Latin American,
Australian and Canadian operations at Chiron Vision, which position he held 
since 1985.

     Jeffrey Anderson joined the Company in 1997 as Director of Regulatory
Affairs and Quality Assurance. In January 1998, Mr. Anderson was appointed to
the office of Vice President--Regulatory Affairs and Quality Assurance. Prior to
joining the Company, Mr. Anderson served as Manager of Regulatory Affairs and
Quality Assurance for Laser Medical Technology from 1991 until 1993. From
December 1993 until November 1995, Mr. Anderson served as a Regulatory Affairs
Specialist for Sybron Dental Specialties and from November 1995 until joining
the Company, he served as Regulatory Affairs Manager for Medtronic.

     Tom Hazen joined the Company in October 1997 as Executive Vice 
President--Operations. From 1992 until joining the Company, Mr. Hazen had
previously served as Vice President of Operations with Imagyn Medical.

                           DESCRIPTION OF SECURITIES

   The following description of the Company's capital stock and selected
provisions of its Articles of Incorporation and Bylaws is a summary and is
qualified in its entirety by the Company's Articles of Incorporation and Bylaws,
copies of which have been filed with the Securities and Exchange Commission.

COMMON STOCK

   
   The Company is authorized to issue 35,600,000 shares of Class A Common Stock,
no par value, 2,200,000 shares of Class E-1 Common Stock, no par value, and
2,200,000 shares of Class E-2 Common Stock.  The Class A Common Stock, Class E-1
Common Stock and the Class E-2 Common Stock have equal voting rights and are
entitled to share equally in dividends from sources available therefor when, as
and if declared by the Board of Directors.  Holders of Class A Common Stock have
no preemptive rights and no right to convert their Common Stock into any other
securities.  The holders of each class of Common Stock are entitled to one vote
for each share held of record on all matters submitted to a vote of the
shareholders, except that holders of Common Stock are entitled to cumulative
voting with respect to the election of directors upon giving notice as required
by law.  In cumulative voting, the holders of Common Stock are entitled to cast
for each share held the number of votes equal to the number of directors to be
elected.  In the event of a liquidation, dissolution or winding up of the
Company, holders of Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities and the liquidation preference of any
then outstanding Preferred Stock.  There are no redemption or sinking fund
provisions applicable to the Common Stock.  All outstanding shares are, and all
shares to be sold and issued as contemplated hereby will be, fully paid and
nonassessable and legally issued.  The Board of Directors is authorized to issue
additional shares of Common Stock within the limits authorized by the Company's
charter and without shareholder action.  As of March 10, 1998, there were
14,838,557 shares of Class A Common Stock outstanding.    

   CLASS E-1 COMMON STOCK
   
   The Company is authorized to issue 2,200,000 shares of Class E-1 Common
Stock, no par value. As of March 10, 1998, there were outstanding 1,257,178
shares of Class E-1 Common Stock and 1,257,178 shares of Class E-2 Common Stock
(the "Escrow Shares").  The Escrow Shares are not transferrable (but may be
voted), and each Escrow Share will automatically convert into one share of
Common Stock and be released to the owners thereof upon the achievement of the
objectives described below.  On June 30, 2000, all Escrow Shares not previously
converted into Common Stock will be cancelled.  This arrangement was required by
the representative of the underwriters for the Company's initial public offering
as a condition of such offering.     

   All of the Class E-1 Common Stock will be automatically converted into Class
A Common Stock in the event that the Company's net income before provision for
income taxes, as defined, exceeds certain amounts.  These amounts were
originally $6,850,000, $8,425,000, and $9,900,000 for the fiscal years ending
March 31, 1998 through 2000, respectively, but these amounts will be increased
in future fiscal years in proportion to increases in the weighted average number
of shares of Class A Common Stock outstanding (as defined) in the relevant year,
as compared to the number of shares outstanding immediately after the Company's
initial public offering in 1994.  
 
                                     -18-
<PAGE>
 
   CLASS E-2 COMMON STOCK

   The Company is authorized to issue 2,200,000 shares of Class E-2 Common
Stock, no par value. All of the shares of Class E-2 Common Stock will be
automatically converted into Class A Common Stock in the event that the
Company's net income before provision for income taxes, as defined, amounts to
at least $14,750,000, $20,475,000 or $26,750,000 for years March 31, 1998
through 2000, respectively (which amounts shall be adjusted in the same manner
as those for the Class E-1 Common Stock).  

   Any money, securities, rights or property distributed in respect of the
Escrow Shares, including any property distributed as dividends or pursuant to
any stock split, merger, recapitalization, dissolution or total or partial
liquidation of the Company, shall be held by the Company in escrow until
conversion of the Escrow Shares. If none of the foregoing earnings levels are
attained, the Escrow Shares, as well as any dividends or other distributions
made with respect thereto, will be cancelled. The earnings levels set forth
above were determined by negotiation between the Company and the representative
of the underwriter in the Company's initial public offering and should not be
construed to imply or predict any future earnings by the Company. There can be
no assurance that such earnings levels will be attained or that any or all of
the Escrow Shares will be converted into Common Stock. However, the conversion
to Common Stock of all or any portion of the Escrow Shares may result in a
charge to earnings to the extent that such shares are held by management or
employees.

PREFERRED STOCK

   The Company's authorized preferred stock consists of 20,000,000 shares, no
par value (the "Preferred Stock"), of which 11,150,000 shares have been
cancelled or already designated.  The Board of Directors has the authority,
without further action by the shareholders, to issue from time to time up to
8,850,000 shares of Preferred Stock in one or more series and to fix the
dividend rights and terms, conversion rights, voting rights (whole, limited or
none), redemption rights and terms, liquidation preferences, sinking funds and
any other rights, preferences, privileges and restrictions applicable to each
such series of Preferred Stock.  The purpose of authorizing the Board of
Directors to determine such rights and preferences is to eliminate delays
associated with a shareholder vote on specific issuances.  The issuance of the
Preferred Stock, while providing flexibility in connection with possible
acquisitions and other corporate purposes, could, among other things, adversely
affect the voting power of the holders of Common Stock and, under certain
circumstances, could make it more difficult for a third party to gain control of
the Company.  Such issuance of Preferred Stock could also adversely affect the
distributions on and liquidation preference of the Common Stock by creating more
series of Preferred Stock with distribution or liquidation preferences senior to
the Common Stock.  The Company has no present plan to issue any shares of
Preferred Stock.

Class B Warrants
    
   Each Class B Warrant entitles the registered holder to purchase one share of 
Common Stock at an exercise price of $8.00 per share at any time prior to 
November 30, 1999. As of March 10, 1998, the Company had outstanding 
7,592,460 Class B Warrants. The Company has a right to redeem all of the Class B
Warrants at a price of $.05 per Class B Warrant upon not less than 30 days'
prior written notice at any time, provided that before any such redemption can
take place, the last sale price of the Company's Class A Common Stock in the
Nasdaq National Market shall have been in excess of $11.20 per share for 30
consecutive business days ending within 15 days prior to the date of the notice
of redemption. During the 30-day notice period, a holder shall have the option
to exercise his Class B Warrants. This right of redemption shall not apply to
the Class B Warrants that are components of the IPO Unit Purchase Options or the
Secondary Unit Purchase Options which have been granted in connection with 
previous offerings.     

TRANSFER AND WARRANT AGENT

   The Transfer and Warrant Agent for the Company's securities is American Stock
Transfer & Trust Company, New York, New York.

                             PLAN OF DISTRIBUTION

          All or a portion of the Shares being registered on behalf of the
Registered Shareholders may be delivered and/or sold in transactions from time
to time on the Nasdaq National Market at prices prevailing at the time, at
prices related to such prevailing prices or at negotiated prices. The Registered
Shareholders may effect such transactions by selling to or through one or more
broker-dealers, and such broker-dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from the Registered
Shareholders. The Registered Shareholders and any broker-dealers that
participate in the distribution may under certain circumstances be deemed to be
"underwriters" within the meaning of the Securities Act, and any commissions
received by such broker-dealers and any profits realized on the sale of Shares
by them may be deemed to be underwriting discounts and commissions under the
Securities Act. The Registered Shareholders may agree to indemnify such broker-
dealers against certain liabilities, including liabilities under the Securities
Act. In addition, the Company has agreed to indemnify certain of the Registered
Shareholders with respect to the Shares being registered hereunder against
certain liabilities, including, without limitation, certain liabilities under
the Securities Act.

          The Registered Shareholders will pay all commissions, transfer taxes,
and other expenses associated with the sale of Shares by them. The Company has
paid the expenses of the preparation of this Prospectus. The Company has not
made any underwriting arrangements with respect to the sale of Securities being
registered hereunder on exercise of the Warrants. Upon exercise of Warrants, the
Securities will be issued by the Company directly to the persons exercising the
Warrants.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

   The Company's Bylaws provide that the Company will indemnify its directors
and officers to the fullest extent permitted by California law.  The Company is
also empowered under its Bylaws to enter into indemnification contracts with its
directors and officers and certain others and to purchase insurance on behalf of
any person it is required or permitted to indemnify.  Pursuant to this
provision, the Company has entered into indemnity agreements with each of its
directors and executive officers and certain key consultants.

   In addition, the Company's Articles of Incorporation provide that, to the
fullest extent permitted by California law, the Company's directors will not be
liable for monetary damages for breach of the directors' fiduciary duty of care
to the Company or its shareholders. This provision in the Articles of
Incorporation does not eliminate the duty of care, and in appropriate
circumstances equitable remedies such as an injunction or other forms of
nonmonetary relief would remain available under California law. Each director
will continue to be subject to liability for breach of the director's duty of
loyalty to the Company, for acts or omissions involving intentional misconduct
or knowing and culpable violations of law, for acts or omissions that a director
believes to be contrary to the best interests of the Company or its shareholders
or involve the absence of good faith on the part of the director, for any
transaction from which the director derived an improper personal benefit, for
acts or omissions involving a reckless disregard for the director's duty to the
Company or its shareholders when the director was aware or should have been
aware of a risk of serious injury to the Company or its shareholders, for acts
or omissions that constitute an unexcused pattern of inattention that amounts to
an abdication of the director's duty of the Company or its shareholders, for
improper transaction between the director and the Company, for improper
distributions to shareholders and loans to directors and officers or for acts or
omissions by the director as an officer. This provision also does not affect a
director's responsibilities under any other laws, such as the federal securities
laws or state or federal environmental laws.

   There is no pending litigation or proceeding involving a director or officer
of the Company as to which indemnification is being sought, nor is the Company
aware of any pending or threatened litigation that may result in claims for
indemnification by any director or officer.

   The Company believes the foregoing provisions are necessary to attract and
retain qualified persons as directors and officers.

   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.

15.  Indemnification of Directors and Officers.
     ----------------------------------------- 

     The California General Corporations Law provides that California
corporations may include provisions in their articles of incorporation relieving
directors of monetary liability for breach of their fiduciary duty as directors,
except for the liability of a director resulting from (i) any transaction from
which the director derives an improper personal benefit, (ii) acts or omissions
involving intentional misconduct or a knowing and culpable violation of law,
(iii) acts or omissions that a director believes to be contrary to the best
interests of the Registrant or its shareholders or that involves the absence of
good faith on the part of the director (iv) acts or omissions constituting an
unexcused pattern of inattention that amounts to an abdication of the director's
duty to the Registrant or its shareholders, (v) acts or omissions showing a
reckless disregard for the director's duty to the Registrant 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 Registrant or its shareholders, (vi) any improper transaction
between a director and the Registrant in which the director has a material
financial interest, or (vii) the making of an illegal distribution to
shareholders or an illegal loan or guaranty.  The Registrant's Articles of
Incorporation provide that the Registrant's directors are not liable to the
Registrant or its shareholders for monetary damages for breach of their
fiduciary duties to the fullest extent permitted by California law.

     The inclusion of the above provision in the Articles of Incorporation may
have the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter shareholders or management from bringing a
lawsuit against directors for breach of their duty of care, even though such an
action, if successful, might otherwise have benefitted the Registrant and its
shareholders.  At present, there is no litigation or proceeding pending
involving a director of the Registrant as to which indemnification is being
sought, nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any director.

     The Registrant's Articles of Incorporation provide that the Registrant
shall indemnify its directors and officers to the fullest extent permitted by
California law, including circumstances in which indemnification is otherwise
discretionary under California law.  Since the California statute is
nonexclusive, it is possible that certain claims beyond the scope of the statute
may be indemnifiable.  Accordingly, the Registrant has also entered into an
indemnification agreement (the "Indemnification Agreement") with certain of its
directors and officers that requires the Registrant to indemnify such directors
and officers to the fullest extent permitted by law.  Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors,
officers and controlling persons of the Registrant, 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.

     It is intended that the Indemnification Agreements provide a scheme of
indemnification which may be broader than that specifically provided by the
California statute.  It has not yet been determined, however, the degree to
which the indemnification expressly permitted by the California statute may be
expanded.

     Set forth below is a description of the principal provisions of the
Indemnification Agreement:

     First, the Indemnification Agreement imposes upon the Company the burden of
proving that the Indemnified Party has not met the applicable standard of
conduct required for indemnification.  The California statute requires a finding
by the Board of Directors, independent legal counsel, or the stockholders that
the applicable standard of conduct has been met.

                                     II-2
<PAGE>
 
     Second, the Indemnification Agreement provides that litigation expenses
shall be advanced to an Indemnified Party at his or her request, against an
undertaking to repay the amount advanced if it is ultimately determined that he
is not entitled to indemnification for such expenses.  The California statute
provides that such expenses may be advanced against such an undertaking, upon
authorization by the Board of Directors.

     Third, in the event the Company does not pay a requested indemnification
amount, the Indemnification Agreement allows such Indemnified Party to contest
this determination by petitioning a court to make an independent determination
of whether such indemnified Party is entitled to indemnification under the
Indemnification Agreement.  The California statute does not set forth the
procedure for contesting a corporation's determination of a party's right to
indemnification.

     Finally, the Indemnification Agreement explicitly provides that actions by
an Indemnified Party at the request of the Company as a director, officer or
agent of an employee benefit plan, corporation, partnership, joint venture or
other enterprise owned or controlled by the Company shall be covered by the
indemnification.  The California statute does not specifically address this
issue.  It does, however, provide that to the extent that an Indemnified Party
has been successful on the merits, he shall be entitled to such indemnification.

     The Company is not aware of any threatened litigation or proceeding which
may result in a claim for indemnification under the Indemnification Agreement by
any director or officer.

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:

          (i)   Include any Prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

          (ii)  Reflect in the Prospectus any facts or events arising after the
     effective date of the Registration Statement (or the most recent post-
     effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement;

                                     II-3
<PAGE>
 
          (iii) 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;

provided, however, that paragraphs (1) (i) and (1) (ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.

     (2) That for the purpose of determining liability under the Securities Act
of 1933, the Registrant will treat each post-effective amendment as a new
Registration Statement of the securities offered, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (3) To file a post-effective amendment or remove from registration any of
the securities that remain unsold at the end of the offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities as the time shall be deemed to be
the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 15 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 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 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, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
