                            EACH UNIT CONSISTING OF
                     190 SHARES OF CLASS A COMMON STOCK AND
                         95 REDEEMABLE CLASS B WARRANTS
    
 
   
    Each unit ("Unit") of  Premier Laser Systems,  Inc. (the "Company")  offered
hereby  consists of 190 shares  of Class A Common Stock,  no par value ("Class A
Common Stock") and  95 redeemable  Class B  Warrants ("Class  B Warrants").  The
Class  B Warrants  are immediately  exercisable and  are transferable separately
from the Class A Common Stock. The number of shares of Class A Common Stock  and
Class  B  Warrants included  in  each Unit  has  been determined  by  D.H. Blair
Investment Banking Corp.  (the "Underwriter") based  primarily upon the  current
market  price  of  the  Class  A Common  Stock,  as  well  as  the Underwriter's
determination of the number of shares and Class B Warrants per Unit necessary to
successfully market the Units in light of  the size of the offering made  hereby
(the  "Offering")  relative to  the number  of  shares of  Class A  Common Stock
outstanding immediately  prior to  the  Offering. Fractional  Units may  not  be
purchased in the Offering.
    
 
    Each  Class B Warrant entitles the registered holder thereof to purchase one
share of Class A Common Stock for $8.00, subject to adjustment, at any time from
the date of issuance  through November 30, 1999.  Commencing November 30,  1997,
the  Class  B  Warrants  will be  subject  to  redemption by  the  Company  at a
redemption price of $.05  per Warrant on 30  days' written notice provided  that
the  average closing bid price as reported by the Nasdaq Stock Market ("Nasdaq")
of the Class A Common Stock exceeds $11.20 per share for 30 consecutive  trading
days  ending within  15 days  of the notice  of redemption.  The public offering
price of  the Units  and the  exercise  price and  other terms  of the  Class  B
Warrants were determined by negotiations between the Company and the Underwriter
and are not necessarily related to the Company's asset value, net worth or other
criteria  of value. The  Underwriter is the  subject of an  investigation by the
Securities and Exchange  Commission (the "Commission").  See "Risk Factors"  and
"Underwriting."
 
   
    The  Company's Class A Common  Stock, Class A Warrants  and Class B Warrants
are presently  quoted on  the Nasdaq  National Market.  The last  reported  sale
prices  of the Class A Common Stock and  Class B Warrants on October 14, 1996 as
reported by the Nasdaq  National Market, were $7  3/4 and $1 3/4,  respectively.
The  Units offered hereby will not be listed on Nasdaq. The Class A Common Stock
is one of  three classes of  the Company's  Common Stock. The  Company also  has
outstanding publicly traded units (the "IPO Units"), each IPO Unit consisting of
one  share of Class A Common Stock, one  Class A Warrant and one Class B Warrant
sold in the Company's initial public offering in December 1994. See "Description
of Securities."

                                  THE COMPANY
 
    Premier Laser Systems, Inc. develops, manufactures and markets several lines
of  proprietary  medical  lasers,  fiberoptic  delivery  systems  and associated
products  for  a  variety  of  dental,  ophthalmic  and  surgical   applications
principally  for  use in  surgical centers  and  medical offices.  The Company's
lasers and related products use the controlled application of thermal,  acoustic
and  optical  energy  to allow  the  physician  or dentist  to  perform selected
minimally invasive  procedures which,  compared to  conventional techniques  not
involving  the use of lasers,  vaporize or sever tissue  with minimal blood loss
and scarring, increase  patient comfort  and reduce patient  treatment time  and
treatment costs.
 
    The  Company's  product line  of proprietary  lasers includes  argon, diode,
CO(2), 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  teeth whitening,  treatment  of endometriosis,
treatment of gum disease,  laparoscopic procedures, 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
Company  also manufactures a  variety of disposable  fiberoptic delivery systems
and sculpted fiberoptic probes, optical tips, waveguides and catheters which are
designed for single-patient use. The Company believes that the increasing demand
for product  sterility  and cost  containment  will  result in  an  increase  in
disposable product sales and will provide a recurring revenue stream.
 
    In  dentistry,  the Company  currently markets  its  lasers for  soft tissue
(gums) procedures, composite  curing in cavity  preparation and teeth  whitening
procedures.  The Company's Aurora diode laser  is currently used by dentists and
periodontists to treat periodontal disease and has been shown to postpone or  in
some  cases  eliminate  the  need  for  conventional  periodontal  surgery.  The
Company's Arago and MOD (Multi Operatory Dentalaser) argon lasers are  currently
used  by  dentists  to accelerate  the  curing  of composites  placed  in cavity
preparations. The use of the laser for this application has been shown to result
in a stronger restoration  than composites cured  by traditional curing  lights.
The Company is seeking clearance for additional dental applications to enable it
to  market its Centauri Er:YAG laser for  hard tissue (teeth) procedures, and is
currently initiating clinical trials for cavity prevention.
 
    Medical lasers have been  used for the treatment  of eye disorders for  many
years  and  are  widely  accepted in  the  ophthalmic  community.  The Company's
multiple application Centauri Er:YAG laser is priced significantly below current
single purpose refractive lasers and  has been cleared for anterior  capsulotomy
(one  step in  the cataract  extraction procedure)  and occuloplastic  and other
cosmetic procedures,  among  other  indications.  The  Centauri  laser  is  also
currently  being  tested  in clinical  trials  and animal  studies  for cataract
removal,  glaucoma  treatment  and  corneal  sculpting  (treatment  of   myopia,
hyperopia and astigmatism).
 
    The  Company  believes  surgical  lasers,  either  in  conjunction  with  or
independent of traditional  sutures or staples,  may be used  for various  wound
closure  procedures.  The  Company believes  that  the  benefits of  the  use of
surgical lasers for tissue melding, as compared to sutures and staples,  include
fluid-static  seals, immediate closure  strength and reduced  surgical time. The
Company and its strategic partner  are currently conducting clinical and  animal
studies  for tissue melding for  ducts, arteries, veins and  skin, in support of
future regulatory applications.

    The Company's strategy is to seek to increase its market penetration in  the
dental,  ophthalmic  and surgical  markets by  (i)  expanding its  marketing and
distribution efforts, (ii) creating market awareness through increased publicity
and the  education of  dentists and  physicians, (iii)  pursuing clearances  for
additional  laser  applications,  (iv)  capitalizing  on  disposable aftermarket
related products,  and (v)  expanding domestically  and internationally  through
strategic  alliances or  acquisitions of companies  with additional distribution
channels, complementary products or an international presence.
 
    The  Company   commenced  operations   in  August   1991,  after   acquiring
substantially  all of the assets  of Pfizer Laser Systems,  a division of Pfizer
Hospital Products  Group, Inc.  ("Pfizer HPG"),  in an  acquisition led  by  the
Company's  Chief Executive Officer. The assets  acquired by the Company included
the proprietary rights  to a broad  base of laser  and fiberoptic  technologies,
which  the  Company developed  over the  past  four years  into 19  laser models
cleared for  market  introduction.  Following  an  initial  public  offering  in
December  1994, the  Company increased inventory  and expanded  its dental sales
force in December 1995  to include five area  sales managers and 25  independent
marketing  representatives. As a result of  this expansion, the Company achieved
$723,000 in sales to the dental market for the fiscal year ended March 31, 1996.
 
    The Company has not generated significant revenues to date, and may continue
to incur losses for the foreseeable  future due to substantial costs  associated
with  manufacturing, marketing and distributing its laser products and continued
research and development related to additional applications for these products.
 
    The Company's principal executive offices  are located at 3 Morgan,  Irvine,
California 92718. The Company's telephone number is (714) 859-0656.

    to increase weighted average shares outstanding by 76,875 and 321,099 shares
    for the fiscal years ended March 31, 1994 and 1995, respectively.
 
(3)  Adjusted to reflect  the receipt by  the Company of  estimated net proceeds
    from the issuance of 11,000 Units offered hereby and the application of  the
    net proceeds thereof. See "Use of Proceeds" and "Capitalization."

                                  RISK FACTORS
 
    In  evaluating  an  investment  in  the  securities  being  offered  hereby,
investors should consider  carefully the  following principal  risk factors,  as
well as the other information contained in this Prospectus.
 
    LIMITED  OPERATING HISTORY;  CONTINUING OPERATING  LOSSES.   The Company was
formed in July 1991 and  has not generated significant  revenues to date. As  of
June  30, 1996, the Company  had an accumulated deficit  of $19,313,474. For the
three months ended June 30, 1996 and the fiscal years ended March 31, 1994, 1995
and 1996, the Company had  operating losses of $689,866, $2,762,645,  $3,867,675
and  $5,851,932,  respectively,  resulting principally  from  costs  incurred in
research and development and other costs of operations. The Company expects that
operating losses  will  continue  until  such time  as  product  sales  generate
sufficient  revenues to fund its continuing operations, as to which there can be
no assurance.
 
    INDEPENDENT ACCOUNTANTS' REPORT;  GOING CONCERN QUALIFICATION.   The  report
from  the Company's  independent accountants  includes an  explanatory paragraph
which describes  substantial doubt  concerning  the ability  of the  Company  to
continue  as a going concern.  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.  See  "Management's  Discussion  and  Analysis  of
Financial  Condition  and Results  of Operations"  and "Financial  Statements --
Report of Independent Accountants."
 
    UNCERTAINTIES CONCERNING  FUTURE PROFITABILITY.   The  Company's ability  to
achieve  profitability  will depend,  in  part, on  its  ability to  continue to
successfully develop clinical applications  and obtain regulatory approvals  for
its products and to 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 and effective  products,
develop  marketing  expertise and  enlarge  its sales  force.  See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    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  dentists and physicians 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 facilitate the general acceptance of
its products. See "Business -- Market Overview."
 
    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. The
 
                                       7
<PAGE>
Company's inability to obtain sufficient quantities of this specialized  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. The Company's arrangement with the
supplier of  its Arago  argon laser  terminates in  November 1996,  and if  this
arrangement  is not renewed and  the Company is unable  to secure another source
for this  argon laser,  the Company's  results of  operations may  be  adversely
affected.  There can be  no assurance that  this or any  other supplier could be
replaced in a timely manner. Any interruption  in the supply of these and  other
key  components can have a  material adverse effect on  the Company's ability to
manufacture its products and, consequently, on its business, financial condition
and results of operations. See "Business -- Manufacturing and Materials."
 
    RISKS APPLICABLE TO FOREIGN SALES.  For the years ended March 31, 1994, 1995
and 1996, sales to foreign markets accounted for approximately 22%, 63% and 40%,
respectively, of the Company's  net 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. See "Business
- -- Marketing, Sales and Service."
 
    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. See
"Business -- Research and Development."
 
   
    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. The  Company holds  19 United States
patents and has  other patent  applications pending  in the  United States.  The
Company  also holds 13  foreign patents including two  utility model patents and
has other foreign patent  applications pending. No assurance  can be given  that
any  additional United States or foreign 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 for the Er:YAG laser. In the past, the Company has
received allegations that certain of the Company's laser products infringe other
patents. 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
    
 
                                       8
<PAGE>
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.
 
   
    POTENTIAL  CHARGES RESULTING  FROM WRITE-OFFS OF  INTANGIBLES.   At June 30,
1996, the Company's  financial statements  reflect patents,  licenses and  other
intangible  assets in the  approximate net amount of  $7,211,072 which amount is
being amortized over the next two to 15 years. Accordingly, the Company  expects
to  recognize a charge to earnings of approximately $700,000 for the fiscal year
ending March 31, 1997, and expects to continue to recognize substantial  charges
to earnings in subsequent fiscal years. 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") and  the regulations promulgated
thereunder. 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.
There can be no assurance that some  of the Company's products will not  require
the  more rigorous  and time  consuming PMA  approval, including  laser uses for
vasovasotomy or other  tissue melding,  dental hard  tissue, cavity  prevention,
cosmetic surgery, sclerostomy and lens emulsification, among others. Filings and
governmental  approvals may be required in  foreign countries before the devices
can be  marketed in  these countries.  There can  be 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 clearances  or approvals  will be  obtained. FDA  or other
governmental clearances or 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. There also  can
be no assurance that any such clearance of modifications would be granted should
it  become  necessary. 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 periodic  inspections  by  state and
federal agencies,  including  the  FDA,  the  California  Department  of  Health
Services,   and  comparable  agencies  in  other  countries.  See  "Business  --
Government Regulation."
 
                                       9
<PAGE>
    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, Chief  Executive  Officer, President  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 has
no long-term 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. See "Management."
 
   
    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, diode,  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.  See  "--  Dependence  on
Suppliers" and "Business -- Competition."
    
 
    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 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  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. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
    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 that  the net proceeds of  the Offering, together with  its
available  short-term assets and  investment income, will  be sufficient to meet
its operating expenses and capital expenditures through the next 12 months.  See
"Use  of  Proceeds"  and  "Management's  Discussion  and  Analysis  of Financial
Condition and  Results  of  Operations  --  Liquidity  and  Capital  Resources."
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
 
                                       10
<PAGE>
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.
 
    BROAD DISCRETION  OVER  USE OF  PROCEEDS.   The  Company  intends to  use  a
substantial  portion of the net proceeds of the Offering to expand the Company's
marketing and distribution capabilities through internal development,  strategic
alliances and acquisitions. In addition, the Company may use of a portion of the
net  proceeds  to  increase  its  available  technologies  or  products  through
acquisitions, capital and research and development expenditures or a combination
or both. Management's allocation decisions concerning such net proceeds will  be
dependent  upon  a variety  of factors,  including the  progress and  results of
clinical trials, the  timing of  receipt of regulatory  approvals and  potential
strategic  alliances and acquisitions. The Company is not engaged in discussions
relating to any acquisitions and has not  yet determined the extent to which  it
will  expand  its  marketing, distribution,  technologies  and  products through
acquisitions or strategic alliances,  as contrasted with  internal growth. As  a
result,  a  significant  portion  of  the net  proceeds  will  be  available for
acquisitions and  projects  that  are  not yet  identified,  and  the  Board  of
Directors  will have  broad discretion with  respect to the  application of such
proceeds. There can be no assurance that the Company will be able to  consummate
acquisitions   or  identify  and  arrange   projects  that  meet  the  Company's
requirements. Approximately $500,000 of the net proceeds will be used to pay  in
full  a  note  due  to Pfizer  HPG  which  is secured  by  certain  tangible and
intangible assets  of the  Company. The  Company  has not  made a  payment  with
respect  to this note that was due in  July 1996, but is attempting to negotiate
an extension of this payment date. No assurance can be given, however, that such
extension will be granted  or that Pfizer  will not seek  to enforce its  rights
under such note. See "Use of Proceeds."
 
    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 Company's securities. In  addition,
the market price of the Company's 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 Company's securities. See "Price Range of Securities."
 
    PRODUCT  LIABILITY  EXPOSURE.   The  sale  of the  Company's  laser products
involves the inherent risk of product liability claims against the Company.  The
Company  currently maintains product liability  insurance coverage in the 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's business,  financial  condition and
results of operations. See "Business -- Product Liability and Insurance."
 
    LIMITATIONS ON THIRD PARTY REIMBURSEMENT.  The Company's laser products  are
generally purchased by physicians, dentists and surgical centers which then bill
various  third party payors,  such as government  programs and private insurance
plans, for  the  procedures conducted  with  the Company's  lasers.  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
 
                                       11
<PAGE>
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. 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  legislation
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. See "Business -- Government Regulation."
 
    CHARGE TO EARNINGS IN THE  EVENT OF RELEASE OF  ESCROW SHARES.  The  Company
has outstanding 1,256,818 shares of each of Class E-1 and Class E-2 Common Stock
which  are being held by the Company in  escrow, and which will be released from
escrow and converted into shares of Class A Common Stock if certain criteria are
met. In  the event  any of  these criteria  are met  and any  Escrow Shares  are
released  from escrow to shareholders 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. See "Management's Discussion and Analysis of Financial Condition and
Results  of  Operations  --  Potential  Future  Charge  to  Income,"  "Principal
Shareholders" and "Description of Securities -- Common Stock."
 
   
    SHARES ELIGIBLE FOR FUTURE SALE; POTENTIAL ADVERSE EFFECT ON MARKET PRICE OF
CLASS  A  COMMON  STOCK  RESULTING  FROM  EFFECT  OF  OUTSTANDING  OPTIONS   AND
WARRANTS.   Sales of a  substantial number of shares of  Class A Common Stock in
the public market following the Offering could adversely affect the market price
for the Class A Common Stock. Other than 161,352 shares of Class A Common  Stock
held  by the  Company's officers, directors  and certain  shareholders which are
subject to  13 month  lock-up  agreements, substantially  all of  the  Company's
6,840,554  shares of Class A  Common Stock to be  outstanding upon completion of
the Offering  will be  freely tradeable,  including the  shares offered  hereby,
3,708,997  registered shares of Class A  Common Stock which have been previously
registered under the Securities Act and 1,041,557 unregistered shares of Class A
Common Stock which may be sold in  the public market subject to compliance  with
Rule  144 promulgated under the Securities  Act. An additional 11,367,347 shares
of Common Stock are issuable upon the full exercise of the Company's outstanding
publicly traded  Warrants, and  2,380,336 shares  of Class  A Common  Stock  are
issuable  upon exercise of other outstanding  warrants and options. The issuance
of shares upon the exercise of  the outstanding Warrants, the IPO Unit  Purchase
Options  and options under the 1995 Stock  Option Plan has been registered under
the Securities Act,  and 718,680 shares  of Class A  Common Stock issuable  upon
exercise  of the remaining options  and warrants may be  resold pursuant to 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 Class A Common
Stock issued upon exercise of such options and warrants will likely be less than
the market  price of  the Class  A Common  Stock at  the time  such options  and
warrants  are exercised. Moreover, the holders of the options and warrants might

needed  capital by a new offering of its securities on terms more favorable than
those provided for by the options and warrants. See "Management -- Stock  Option
Plans" and "Shares Eligible for Future Sale."
 
    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  shareholder  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 Company's 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. See "Description  of
Securities -- Preferred Stock."
 
    POTENTIAL  ADVERSE EFFECT OF  REDEMPTION OF CLASS  B WARRANTS.   The Class B
Warrants may be redeemed by the Company at any time commencing November 30, 1997
at a redemption price of  $.05 per Class B Warrant  upon 30 days' notice if  the
average  closing  bid prices  (or  last sales  prices  if listed  on  a national
securities exchange)  of  the  Class  A  Common  Stock  exceeds  $11.20  for  30
consecutive  trading days  ending within  15 days  of the  notice of redemption.
Redemption of the Class B Warrants could  force the holders (i) to exercise  the
Class  B  Warrants  and  pay  the  exercise price  at  a  time  when  it  may be
disadvantageous for the holders to do so,  (ii) to sell the Class B Warrants  at
the then current market price when they might otherwise wish to hold the Class B
Warrants, or (iii) to accept the nominal redemption price, which is likely to be
substantially  less than the market value of the Class B Warrants at the time of
redemption. See "Description of Securities -- Redeemable Warrants."
 
    CURRENT  PROSPECTUS   AND   STATE   REGISTRATION   TO   EXERCISE   CLASS   B
WARRANTS.   Holders of  Class B Warrants  will be able  to exercise the warrants
only if  (i) a  current prospectus  under  the Securities  Act relating  to  the
securities  underlying the  Class B  Warrants is  then in  effect and  (ii) such
securities are  qualified  for  sale  or exempt  from  qualification  under  the
applicable securities laws of the states in which the various holders of Class B
Warrants reside. Although the Company has undertaken and intends to use its best
efforts  to maintain a current prospectus covering the securities underlying the
Class B Warrants following completion of the Offering to the extent required  by
federal securities laws, there can be no assurance that the Company will be able
to  do  so. The  value of  the  Class B  Warrants may  be  greatly reduced  if a
prospectus covering the  securities issuable upon  the exercise of  the Class  B
Warrants  is not kept current or if  the securities are not qualified, or exempt
from qualification,  in the  states in  which the  holders of  Class B  Warrants
reside.  Persons holding Class  B Warrants who reside  in jurisdictions in which
such securities are not  qualified and in  which there is  no exemption will  be
unable  to exercise their Class  B Warrants and would  either have to sell their
Class B Warrants in the open market or allow them to expire unexercised. If  and
when  the Class B Warrants  become redeemable by the  terms thereof, the Company
may exercise its redemption right even if it is unable to qualify the underlying
securities for sale under all applicable state securities laws. See "Description
of Securities -- Redeemable Warrants."
 
    POSSIBLE ADVERSE EFFECT ON LIQUIDITY OF THE COMPANY'S SECURITIES DUE TO  THE
INVESTIGATION  OF D.H. BLAIR INVESTMENT BANKING CORP. AND D.H. BLAIR & CO., INC.
BY THE SECURITIES  AND EXCHANGE  COMMISSION.   The Commission  is conducting  an
investigation concerning various business activities of the Underwriter and D.H.
Blair  & Co., Inc. ("Blair & Co."), a selling group member which will distribute
substantially all of the Units offered  hereby. The investigation appears to  be
broad  in scope,  involving numerous  aspects of  the Underwriter's  and Blair &
Co.'s compliance  with  the federal  securities  laws and  compliance  with  the
federal  securities laws  by issuers whose  securities were  underwritten by the
Underwriter or Blair  & Co., or  in which the  Underwriter or Blair  & Co.  made
over-the-counter  markets, persons  associated with  the Underwriter  or Blair &
Co., such  issuers  and other  persons.  The Company  has  been advised  by  the
Underwriter that the investigation has been ongoing since at least 1989 and that
the Underwriter is cooperating with the investigation. The
 
                                       13
<PAGE>
Underwriter  cannot predict whether  this investigation will  ever result in any
type of formal enforcement action against the Underwriter or Blair & Co., or, if
so, whether any  such action might  have an adverse  effect on the  Underwriter,
Blair  & Co. or the securities offered hereby. The Company has been advised that
Blair & Co., which has  continued to make a  market in the Company's  securities
since  the  IPO,  intends to  make  a  market in  the  securities  following the
Offering. An unfavorable resolution of the Commission's investigation could have
the effect of limiting  such firm's ability  to make a  market in the  Company's
securities,  which could affect  the liquidity or price  of such securities. See
"-- Adverse Effect on Liquidity Associated with Possible Restrictions on  Market
Making Activities in the Company's Securities" and "Underwriting."
 
    ADVERSE  EFFECT ON LIQUIDITY ASSOCIATED WITH POSSIBLE RESTRICTIONS ON MARKET
MAKING ACTIVITIES IN THE COMPANY'S SECURITIES.  The Underwriter has advised  the
Company  that Blair & Co. intends to continue  to make a market in the Company's
securities. Rule 10b-6 promulgated under the Securities Act of 1934, as  amended
(the "Exchange Act") may prohibit Blair & Co. from engaging in any market-making
activities  with  regard to  the  Company's securities  for  a period  from nine
business days (or such other applicable period as Rule 10b-6 may provide)  prior
to any solicitation by the Underwriter of the exercise of the Warrants until the
later  of the termination  of such solicitation activity  or the termination (by
waiver or otherwise) of any right that the Underwriter may have to receive a fee
for the exercise of Warrants following  such solicitation. As a result, Blair  &
Co.  may  be unable  to provide  a  market for  the Company's  securities during
certain periods while the Warrants  are exercisable. Any temporary cessation  of
such  market-making activities could have an  adverse effect on the market price
of the Company's securities.
 
                                USE OF PROCEEDS
 
   
    The net proceeds  to the Company  from the  sale of the  11,000 Units  being
offered   hereby  are  estimated  to  be   $9,200,000  (or  $10,676,750  if  the
Underwriter's Over-Allotment  Option  is  exercised  in  full)  after  deducting
underwriting discounts and estimated offering expenses payable by the Company.
    
 
    The  Company intends  to use the  net proceeds  of the Offering  to fund the
expansion of the  Company's marketing and  distribution capabilities,  including
distribution   into  international  markets,   through  acquisitions,  strategic
alliances or internal development. The Company also plans to invest in inventory
and demonstration  or loaner  equipment,  and to  fund additional  research  and
development including further clinical trials.
 
    The Company also plans to use approximately $1.6 million of the net proceeds
of  the Offering to repay  outstanding indebtedness including approximately $1.1
million  in  trade   payables  and  approximately   $500,000  representing   the
outstanding  principal and unpaid accrued interest  on a promissory note payable
to Pfizer HPG representing acquisition  indebtedness, which note bears  interest
at the rate of 10.0% per annum, and matures on the closing of the Offering.
 
    The remaining proceeds are expected to be used for working capital and other
general  corporate  purposes,  including possible  strategic  alliances  with or
acquisitions of businesses that may provide distributor networks,  complementary
products  or  an  international  presence. There  are  no  present negotiations,
agreements or understandings with  respect to any  such acquisitions. Because  a
significant  portion of the net proceeds  will be available for acquisitions and
projects that are  not yet identified,  the Board of  Directors will have  broad
discretion  with respect to  the application of  such proceeds. There  can be no
assurance that the Company  will be able to  identify and arrange projects  that
meet the Company's requirements or to consummate any such acquisition.
 
    Pending  the application of such proceeds, the Company intends to invest the
net proceeds of the Offering in  bank deposits and short-term, investment  grade
securities.

 *  For April 1 through April 30, 1995, the high and low bid prices of the Class
    A Common Stock Class A Warrants and Class B Warrants were $5 and $3 1/2,  $1
    and $ 15/16, and $ 3/4 and $ 1/2, respectively.
 
    The quotations in the above table reflect inter-dealer prices without retail
markups,  markdowns or commissions. In addition, for all periods prior to May 1,
1995, the quotations do not represent actual transactions.
 
   
    On October 14, 1996, the last reported sale prices for the Company's Class A
Common Stock, Class  A Warrants and  Class B Warrants  were $7 3/4,  $4 5/8  and
$1  3/4,  respectively, on  the  Nasdaq National  Market.  The Company  also has
outstanding Class E-1 Common Stock and Class E-2 Common Stock for which there is
no public market. See "Description of  Securities." As of October 14, 1996,  the
approximate  number of holders of record of  the Company's Class A Common Stock,
Class E-1 and Class  E-2 Common Stock  were 261, 323  and 323 respectively.  The
Company  believes that there  are a substantial  number of additional beneficial
holders of Class A Common Stock.
    
 
                                DIVIDEND POLICY
 
    The Company has not declared or paid any cash dividends on its capital stock
since its inception and for the foreseeable future intends to follow a policy of
retaining all of its earnings, if any, to finance the development and  continued
expansion of its business. There can be no assurance that dividends will ever be
paid  by the Company. Any  future determination as to  payment of dividends will
depend upon the Company's  financial condition, results  of operations and  such
other  factors  as  the Board  of  Directors  deems relevant.  In  addition, the
Company's credit  facility  with Silicon  Valley  Bank prohibits  the  Company's
payment   of  any  dividends  without  the  prior  consent  of  such  bank.  See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations -- Liquidity and Capital Resources."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion and analysis should be read in conjunction with the
Selected Financial Data and the Company's Financial Statements and related notes
thereto  appearing  elsewhere  in  this  Prospectus.  This  Prospectus  contains
forward-looking statements including, without limitation, statements  concerning
future  cost  of sales,  which involve  risks  and uncertainties.  The Company's
actual results  may differ  significantly from  the results  discussed in  these
forward-looking statements. Factors that may cause such differences include, but
are not limited to, those discussed in "Risk Factors."
 
GENERAL
 
    The  Company develops, manufactures and markets several lines of proprietary
medical lasers,  fiberoptic  delivery  systems and  associated  products  for  a
variety  of dental, ophthalmic and  surgical applications. The Company commenced
operations in August 1991,  after acquiring substantially all  of the assets  of
Pfizer  Laser Systems  ("Pfizer Laser"),  a division  of Pfizer  HPG which  is a
wholly-owned subsidiary  of Pfizer,  Inc.  The assets  acquired by  the  Company
included  the  proprietary  rights  to  a broad  base  of  laser  and fiberoptic
technologies developed by Pfizer Laser.
 
    Since its  formation  and  until  its IPO  in  December  1994,  the  Company
principally  focused on, and its research and development activities related to,
growing markets  in dentistry,  ophthalmology, cosmetic  procedures and  certain
surgical  specialties to  be used  in surgical  centers and  medical offices. To
implement this strategy, the Company  developed the Pegasus Nd:YAG dental  laser
system  from existing technology and introduced  this laser to the dental market
in February 1992. In June 1993, the Company introduced the Centauri Er:YAG laser
for ophthalmology and initiated  clinical trials for  hard tissue procedures  in
dentistry.  In  December 1993,  the Company  acquired  from Proclosure,  Inc., a
Florida corporation ("Proclosure"), certain  technology, assets and  proprietary
rights  relating to  a 1.32m  Nd:YAG laser system  for tissue  melding. From its
formation in 1991 through its IPO, the Company developed and received regulatory
approvals for 15 models of  lasers and sold certain  of those products for  soft
tissue  applications in  dentistry and as  part of clinical  trials conducted by
third parties.
 
    After the  Company's  IPO  in  December  1994,  the  Company  increased  its
inventory,  acquired the  distribution rights to  two new dental  lasers and, in
December 1995, expanded its dental sales force. In September and November  1995,
the  Company acquired rights  to market and  distribute the Arago  and MOD argon
lasers, respectively for dental applications, and in February 1996, the  Company
introduced  and began  shipping its  Aurora diode  laser for  soft tissue dental
applications.
 
    While the Company has received clearance to market laser products covering a
variety of medical applications, to date  the Company has focused its  research,
development   and  marketing  efforts  on  a   limited  number  of  products  or
applications (principally  specific  dental  and  ophthalmic  applications).  As
future  resources  permit,  the  Company  may  introduce  certain  products  for
applications for  which it  already  has all  necessary  approvals or  may  seek
strategic alliances to develop, market and distribute such products.
 
    The  Company has recorded operating losses in each of the fiscal years since
its formation, resulting principally from substantial costs incurred in research
and development activities and obtaining regulatory approvals, together with the
absence of significant revenues to date  primarily due to the Company's  limited
marketing  and financial  resources, the  Company's inability  to obtain certain
critical components  and lasers  from  time to  time,  and until  recently,  the
limited  acceptance of lasers in the medical industry, in general. The report of
the  Company's  independent  accountants   includes  an  explanatory   paragraph
describing  substantial doubt concerning the ability  of the Company to continue
as a going concern. The Company believes, however, that its presently  available
short-term assets, expected revenues from operations and the net proceeds of the
Offering will provide sufficient working capital through the next 12 months. See
"-- Liquidity and Capital Resources."

RESULTS OF OPERATIONS
 
    QUARTER ENDED JUNE 30, 1996 COMPARED TO QUARTER ENDED JUNE 30, 1995
 
    The  Company's net  sales for  the quarter  ended June  30, 1996  (the "1996
Quarter") increased 1,014.1% to $1,254,082  from $112,564 for the quarter  ended
June  30, 1995 (the  "1995 Quarter"). The increase  is primarily attributable to
continued growth in sales in the  dental market, principally from the  Company's
three new products, which accounted for $855,654 of the increase. Sales of other
dental,  surgical and ophthalmic products increased by 325.2% to $331,651 in the
1996 Quarter from  $78,005 in  the 1995 Quarter  and included  initial sales  to
Mattan  Corporation (Medical Laser Institute of  America) ("Mattan") for its new
laser centers.
 
    Cost of  sales increased  128.4%  to $1,028,611  in  the 1996  Quarter  from
$450,353  in the  1995 Quarter. This  increase was directly  attributable to the
increase in sales and included a fee of $87,545 to a third party pursuant to the
Company's manufacturing arrangement  relating to  the argon MOD  laser. Cost  of
sales  related to sales  to Mattan were  95% of the  amount of the corresponding
sales due  to the  fact that  the  products sold  were purchased  from  original
equipment  manufacturers, instead  of being manufactured  by the  Company. It is
intended that  as  additional centers  are  opened, the  Company  will  commence
manufacturing  of the lasers  and cost of sales  will only include manufacturing
costs. If production volumes increase in future periods, management  anticipates
higher  absorption  of  manufacturing  costs and  increased  utilization  of the
Company's manufacturing personnel,  which could lead  to positive gross  margins
based  upon management's current  calculation of the  Company's standard cost of
sales for fiscal  1996. There  can be  no assurance  that the  Company will,  in
future periods, achieve positive gross margins, or that the assumptions on which
standard cost of sales is computed will be realized by the Company.
 
    Selling  and marketing  expenses increased  135.8% to  $461,772 in  the 1996
Quarter  from  $195,831  for  the  1995  Quarter.  The  increase  was  primarily
attributable  to marketing  and sales  efforts related  to the  Company's dental
products. These expenses  primarily included increased  commissions and  related
selling  expenses,  expenses  of  sales  and  marketing  personnel,  trade  show
attendance and advertising expenses. Sales and marketing expenses also  included
expenses  relating to the initial  showing of the Company's  Er:YAG laser at the
annual meeting of the American Society of Cataract and Refractive Surgeons.
 
    Research and development expenses  decreased 50.5% to  $126,779 in the  1996
Quarter  from $255,959 in  the 1995 Quarter.  This net decrease  resulted from a
$397,634 cash  reimbursement  received by  the  Company from  a  Small  Business
Innovative  Research  ("SBIR") Grant  which  was partially  offset  by increased
clinical trial costs for certain  ophthalmic applications and expenses  incurred
in the development of the argon MOD laser.
 
    General  and administrative expenses decreased 34.8% to $326,786 in the 1996
Quarter  from  $501,078  in  the  1995  Quarter.  The  decrease  was   primarily
attributable  to a  $58,637 reduction in  annual report  production and printing
expenses which have  been delayed,  and a $50,423  reduction in  "out-of-pocket"
legal  expenses associated with the Company's  litigation with a former supplier
of optical fiber (the "Fiber Litigation").
 
    Net interest income decreased 107.6%, to a net interest expense of $7,194 in
the 1996  Quarter from  net interest  income  of $94,449  in the  1995  Quarter,
reflecting  the  decreased  cash available  for  the  Company to  invest  and an
increase in borrowings under the  Company's credit facility with Silicon  Valley
Bank (the "Credit Facility"). See "-- Liquidity and Capital Resources."
 
    Net  loss decreased 41.7% to $697,060 in the 1996 Quarter from $1,196,208 in
the 1995 Quarter. This  decrease was primarily attributable  to the increase  in
sales  and decreases in research and  development and general and administrative
expenses, offset in part by increases in sales and marketing expenses.
 
                                       19
<PAGE>
    FISCAL YEAR ENDED MARCH 31, 1996 COMPARED TO FISCAL YEAR ENDED MARCH 31,
1995
 
    Net sales increased 36.4%  to $1,704,390 in fiscal  1996 from $1,249,403  in
fiscal 1995. This increase was primarily attributable to an increase of $723,000
in  sales to the dental market, related principally to the introduction of three
new products in  the latter half  of fiscal  1996, the Aurora  diode laser,  the
Arago argon laser and the MOD argon laser. This increase was partially offset by
a  decrease in sales  to the surgical market  of approximately $200,000, largely
due to a decline in  the demand for the Company's  10 and 20 watt CO(2)  lasers,
which are nearing the end of their product life cycle. The Company's arrangement
with  the supplier of the Arago argon  laser terminates in November 1996, and to
the extent the Company is unable to extend this arrangement or to secure another
source for this  laser, the  Company's results  of operations  may be  adversely
affected.
 
    Cost  of sales increased 156.1% to $3,324,757 in fiscal 1996 from $1,298,420
in fiscal 1995. This increase  in the cost of sales  was due primarily to (i)  a
write-down  of approximately  $848,000 principally  attributed to  the Company's
CO(2) lasers and accessories  obtained in the acquisition  of Pfizer Laser,  and
Nd:YAG  lasers and accessories,  which lasers were developed  prior to March 31,
1992  and  are  nearing  the  end   of  their  product  life  cycle,  (ii)   the
underabsorption of manufacturing costs due to low production volumes due in part
to  the unavailability of  certain key components  which require long lead-times
for delivery, coupled with an increase in the number of manufacturing  employees
during  fiscal 1996 from 12 to 17  employees resulting in an increase in payroll
expense of approximately  $280,000, and  (iii) increased  costs associated  with
higher sales volumes in fiscal 1996. Cost of sales for fiscal 1996 also included
a  fee of  $122,000 to  a third  party pursuant  to the  Company's manufacturing
arrangement relating to the MOD argon laser.
 
    Selling and marketing expenses increased 26.3% to $1,308,767 in fiscal  1996
from  $1,035,863 in  fiscal 1995.  This increase  was primarily  attributable to
marketing efforts related  to the  Company's dental products,  which included  a
$219,000  expense related to the appointment  of more than 25 new manufacturer's
representatives during  the third  quarter,  and associated  expenses  including
training, promotional costs and commissions.
 
    Research  and development expenses  increased 17.2% to  $1,213,471 in fiscal
1996 from  $1,035,705 in  fiscal  1995. This  increase resulted  primarily  from
increases  in outside industrial  and software design  services of approximately
$305,000, and expenses of approximately $196,000 associated with the development
of new  laser  products.  This  increase was  partially  offset  by  a  $175,000
reduction  in clinical studies  expense, due to the  completion of the Company's
dental hard  tissue clinical  trials  and a  $250,000  payment received  by  the
Company under a SBIR grant.
 
    General  and administrative expenses decreased  2.2% to $1,709,327 in fiscal
1996 from $1,747,090 in fiscal 1995. This decrease was the result of a reduction
in legal  expenses associated  with the  Fiber Litigation,  partially offset  by
increases  associated  with  becoming a  public  company. In  1995,  the Company
incurred legal expenses of approximately  $400,000 in connection with the  Fiber
Litigation. Future legal expenses related to the Fiber Litigation (not including
out-of-pocket  expenses)  are  expected to  be  limited in  accordance  with the
Company's agreement  with  its legal  counsel,  although if  the  litigation  is
successful, counsel will be entitled to certain contingency fees.
 
    Net  interest income increased  to $99,037 in fiscal  1996 from net interest
expense of $322,540 in fiscal 1995,  reflecting the investment of the  Company's
remaining  net proceeds  from its IPO  and the  repayment in December  1994 of a
significant portion of the Company's outstanding debt.
 
    Net loss increased  51.1% to $5,752,895  in fiscal 1996  from $3,808,485  in
fiscal  1995. This increase was principally attributable to increases in cost of
sales, selling and marketing expenses and research and development expenses.
 
    FISCAL YEAR ENDED MARCH 31, 1995 COMPARED TO FISCAL YEAR ENDED MARCH 31,
1994
 
    Net sales decreased 39.9%  to $1,249,403 in fiscal  1995 from $2,079,335  in
fiscal  1994. Net sales during fiscal 1994 included substantial revenue from the
introduction of the Company's Er:YAG laser.
 
                                       20

Sales in fiscal 1995  of Nd:YAG lasers, Er:YAG  lasers and other laser  products
were  adversely affected by the lack of  working capital to fund the purchase of
inventory components (some of which require  a three month lead time to  supply)
and manufacturing operations, and the limited availability of optical fibers for
the  Er:YAG laser. The decrease in sales  of these products was partially offset
by a general increase in sales of the Company's other products.
 
    Cost of sales decreased 25.9% to  $1,298,420 in fiscal 1995 from  $1,753,352
in fiscal 1994. This decrease was primarily attributable to reduced expenditures
of raw materials resulting from lower sales.
 
    Selling  and marketing expenses decreased 4.7%  to $1,035,863 in fiscal 1995
from $1,087,461 in fiscal 1994.
 
    Research and development  expenses increased 52.7%  to $1,035,705 in  fiscal
1995  from $678,279 in  fiscal 1994 primarily due  to increased efforts directed
towards dental hard tissue clinical  trials and the initial development  efforts
associated with two potential products.
 
    General  and administrative expenses increased 32.1% to $1,747,090 in fiscal
1995 from $1,322,888 in fiscal 1994. This increase was primarily due to expenses
incurred in connection with the Fiber Litigation, which were partially offset by
reductions in management compensation.
 
    Net interest  expense  decreased  25.8%  to $322,540  in  fiscal  1995  from
$434,851 in fiscal 1994.
 
    Net  loss increased  19.1% to $3,808,485  in fiscal 1995  from $3,197,496 in
fiscal 1994.  This  increase reflected  the  decreased  level of  sales  and  an
increase  in research  and development  and general  and administrative expenses
during fiscal 1995. The  net loss for fiscal  1995 included a net  extraordinary
gain of $381,730 from the extinguishment of indebtedness.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The  Company's operations have  been financed through  the proceeds from the
sale of  the  Company's equity  securities,  including the  IPO,  revenues  from
operations, the proceeds from an SBIR grant and funding from the Credit Facility
with  Silicon Valley Bank. The  Company's principal capital requirements include
the financing  of  inventory,  accounts  receivable,  research  and  development
activities,  the development  of an ophthalmic  and a surgical  sales force, the
development of  marketing  programs  and the  acquisition  and/or  licensing  of
patents.
 
    At  June 30, 1996,  the Company had  a cash balance  of $135,881 and working
capital of  $4,449,812. This  represents  an increase  from  March 31,  1996  of
$100,418  in  cash  and  cash  equivalents.  This  increase  in  cash  and  cash
equivalents was largely  due to borrowings  under the Credit  Facility and  cash
received from the exercise of Class A Warrants, partially offset by cash used in
operations.
 
    In  December 1995, the  Company entered into  a strategic marketing alliance
with Mattan,  a Canadian  corporation  whose stock  is  publicly traded  on  the
Alberta  Stock Exchange. Pursuant  to this alliance, the  Company entered into a
Purchasing Agreement with Mattan which provides that the Company will supply all
laser equipment and associated disposables for  all laser surgery centers to  be
designed  and opened by  Mattan in Canada  and the United  States. In connection
with this alliance,  the Company entered  into a Share  Exchange Agreement  with
Mattan  pursuant to  which the  Company issued  200,000 shares  of the Company's
Common Stock to two  parties affiliated with Mattan,  in exchange for  1,150,000
shares of Mattan's Common Stock, which constituted approximately 12% of Mattan's
outstanding Common Stock as of the date of the transaction. The Company accounts
for this investment as an available-for-sale security pursuant to SFAS 115.
 
    At  June 30, 1996,  the Company's indebtedness consisted  of a $481,195 note
payable to Pfizer  HPG (the "Pfizer  Note") and $400,000  due to Silicon  Valley
Bank on the Credit Facility. The Pfizer Note, which is secured by certain of the
Company's  tangible and  intangible assets,  is due  in three  installments. The
first installment of $240,598,  plus accrued interest was  due in July 1996  and
additional $120,299 quarterly principal payments, plus accrued interest, are due
in October 1996 and
 
                                       21
<PAGE>
January  1997. Upon completion  of the Offering,  any remaining unpaid principal
and accrued interest  becomes immediately  due and payable.  Although the  first
installment  was not made in  July 1996, the Company  is attempting to negotiate
with Pfizer HPG for an extension of this payment date. There can be no assurance
that such extension will be granted or that Pfizer will not seek to enforce  its
rights under the Pfizer Note.
 
   
    The Company's Credit Facility with Silicon Valley Bank permits borrowings of
up  to $1,000,000 based on the value of  the 1,150,000 shares of common stock of
Mattan Corporation (the "Mattan Shares")  held by the Company. Borrowings  under
the  Credit Facility are secured by the Mattan Shares, bear interest at the rate
of 1.0% per annum over  the prime rate of interest,  and are due and payable  in
April  1997. In connection with the Credit  Facility, the Company issued to such
lender warrants to purchase up to 9,756  shares of the Company's Class A  Common
Stock  at an exercise price  equal to $10.25 per share.  As of October 14, 1996,
the Company had drawn approximately $1,000,000 on this Credit Facility.
    
 
    At March 31,  1996, the  Company had  net operating  loss carryforwards  for
federal  income tax purposes totaling approximately $16,319,249 which will begin
to expire in fiscal 2007. Net operating loss carryforwards for state income  tax
purposes  totaling approximately $7,895,167 at March 31, 1996 begin to expire in
fiscal 1998. The Tax Reform Act of 1986 includes provisions which may limit  the
net  operating loss carryforwards available for use in any given year if certain
events occur, including significant changes  in stock ownership. Utilization  of
the  Company's net operating  loss carryforwards to offset  future income may be
limited.
 
    The Company's  future  capital requirements  will  depend on  many  factors,
including the progress of the Company's research and development activities, the
scope  and results  of preclinical  studies and  clinical trials,  the costs and
timing of regulatory approvals, the rate of technology advances by the  Company,
competitive  conditions within the medical  laser industry, the establishment of
manufacturing capacity  and the  establishment  of collaborative  marketing  and
other  relationships which may either involve  cash infusions to the Company, or
require additional cash  from the Company.  Management believes that  short-term
assets, cash generated through expected future revenues, the Credit Facility and
SBIR grants and the net proceeds of the Offering will be adequate to satisfy its
working  capital needs for  at least the  next 12 months.  After that period the
Company's ability to  meet its working  capital needs will  be dependent on  its
ability  to  achieve  a  positive  cash  flow  from  operations  and  profitable
operations, in  addition to  its ability  to secure  additional debt  or  equity
financing.  No assurance can be given that the Company will be able to achieve a
positive cash flow from operations, profitable operations or secure financing on
acceptable terms.
 
SEASONALITY OF BUSINESS
 
    To date, the Company's revenues have typically been significantly higher  in
the second and fourth calendar quarters. This seasonality reflects the timing of
major  medical and dental industry trade  shows in these quarters, significantly
reduced sales  during  the  summer and  the  effect  of year  end  tax  planning
influencing  the  purchasing of  capital equipment  for depreciation  during the
fourth calendar quarter. The Company expects that this seasonality will continue
indefinitely.
 
GOVERNMENT GRANTS
 
   
    The Company has been awarded a SBIR grant for approximately $750,000 for the
study of laser  cataract emulsification. Approximately  $698,000 of this  amount
was  drawn at October 14, 1996. The remainder of the grant can be drawn over the
next six months upon the achievement of specified criteria. The Company has also
applied for  new Phase  I  research grants  related to  dentistry,  orthopedics,
tissue  melding and  ophthalmology. No assurance  can be given  that the Company
will be awarded any of these potential government grants.
    
 
POTENTIAL FUTURE CHARGE TO INCOME RESULTING FROM CONVERSION OF ESCROW SHARES
 
    The Commission has adopted a position  with respect to arrangements such  as
the one entered into among the Company and the holders of its outstanding Escrow
Shares which provides that in the
 
                                       22
<PAGE>
event  any shares are released from escrow  to certain persons who are officers,
directors, employees or consultants of the Company, compensation expense will be
recorded for financial reporting purposes. Accordingly, the Company expects,  in
the  event  of  the release  of  the  Escrow Shares  from  escrow,  to recognize
substantial noncash charges to earnings during the periods in which the criteria
for release  of the  Escrow  Shares are  met, which  would  have the  effect  of
significantly increasing the Company's loss or reducing or eliminating earnings,
if  any,  at such  time. The  recognition  of such  compensation expense  by the
Company may  have a  depressive effect  on  the market  price of  the  Company's
securities.
 
    The  Escrow Shares will be automatically converted into Class A Common Stock
(at a conversion  rate of  one share  of Class A  Common Stock  for each  Escrow
Share)  in the  event that  the Company meets  certain criteria  relating to the
market price of the Class  A Common Stock or the  achievement by the Company  of
certain  levels of "income," as defined.  Different criteria relate to the Class
E-1 Common Stock and Class E-2 Common Stock. For these purposes, "income"  means
the  Company's net income before provision  for income taxes, including earnings
from joint  ventures,  distribution  agreements and  licensing  agreements,  but
exclusive  of any other  earnings that are classified  as an extraordinary item,
and exclusive of charges to income that may result from conversion of the Escrow
Shares into  Class  A  Common  Stock,  as  stated  in  the  Company's  financial
statements audited by the Company's independent accountants. See "Description of
Securities -- Common Stock."
 
    If  none of the pretax  net income or market  price levels are attained, the
Escrow Shares, as well as any dividends or other distributions made with respect
thereto, will be cancelled. The pretax  net income and market price levels  were
determined  by negotiation between the Company and the Company's underwriter for
the IPO and should not be construed  to imply or predict any future earnings  by
the  Company or any increase in the market price of its securities. There can be
no assurance that such earnings and market price levels will be attained or that
any or all of the Escrow Shares will be converted into Class A Common Stock.

                                    BUSINESS
 
OVERVIEW
 
   
    The Company develops, manufactures and markets several lines of  proprietary
medical  lasers,  fiberoptic  delivery  systems and  associated  products  for a
variety of dental, ophthalmic and  surgical applications principally for use  in
surgical  centers and medical offices. The Company's lasers and related products
use the controlled application of thermal, acoustic and optical energy to  allow
the  physician  or dentist  to  perform selected  minimally  invasive procedures
which, compared  to conventional  techniques not  involving the  use of  lasers,
vaporize  or sever tissue with minimal blood loss and scarring, increase patient
comfort and reduce  patient treatment  time and  treatment costs.  To date,  the
Company  has received clearance to market 19 models of medical lasers, which are
covered  by  19  United  States   patents,  13  pending  United  States   patent
applications,  13  foreign patents  and 41  pending  foreign patents.  While the
Company has  clearance  to  market  laser products  for  a  variety  of  medical
applications, due to limited resources the Company has focused its marketing and
distribution  efforts to date  on a limited number  of products and applications
(principally specific dental applications) which  the Company believes have  the
most  potential for commercial success. As  future resources permit, the Company
may introduce certain  products for applications  for which it  already has  all
necessary  approvals  or may  seek strategic  alliances  to develop,  market and
distribute such products.
    
 
MARKET OVERVIEW
 
    The use of laser technology in dentistry, ophthalmology and surgery involves
the controlled application  of laser  light to hard  or soft  tissue causing  an
optical,  thermal, acoustic or plasma interaction  with the tissue. When applied
to tissue, the  laser light is  partially absorbed. This  process of  absorption
converts  the light to heat,  which in turn alters the  state of the tissue. The
degree of  tissue absorption  varies with  the choice  of wavelength  and is  an
important  variable in the  application of laser  technology in treating various
tissues. The laser energy  can also form  a gas bubble in  a water medium  which
provides  an acoustic cutting  effect as it  bursts. The Company  often uses its
proprietary delivery systems  to control the  relative proportions of  acoustic,
thermal  and  optical energy  applied to  tissue  resulting in  enhanced cutting
effects.  These  delivery  systems  include  flexible  fiberoptics,  waveguides,
articulated arms and micromanipulators which are used on a disposable or limited
reuse  basis which the  Company intends will provide  a recurring revenue stream
for the Company. The  Company's strategy is to  target specific applications  in
the  dental, ophthalmic and surgical markets, where management believes that the
Company's technology and products have competitive strengths.
 
    DENTAL AND PERIODONTAL MARKET
 
    The current market for laser equipment in dental procedures is comprised  of
soft  tissue procedures, composite  curing and teeth  whitening. If clearance or
approval is obtained,  this market may  be expanded to  include hard tissue  and
cavity prevention procedures.
 
    SOFT  TISSUE.  It  is estimated that over  60 million periodontal procedures
are performed by dentists and periodontists annually in the United States,  many
of  which the  Company believes  can be  addressed with  laser technology.  In a
clinical study  involving  more  than 900  procedures,  periodontists  used  the
Company's lasers during a new minimally invasive surgical technique used in lieu
of  traditional periodontal  flap surgery, for  which technique  the Company has
filed a  patent  application  which  is  pending.  The  results  demonstrated  a
reduction  in bacteria,  improved periodontal pocket  depth, minimal  or no pain
when using  the  laser  even  without  anesthesia,  little  or  no  prescription
medication  following surgery and a substantial reduction in surgical time. This
study also demonstrated that the  dental laser can also  be used to treat  early
gum  disease, postponing or in some  cases eliminating the need for conventional
periodontal surgery.  While  the Company  has  clearance to  market  six  lasers
(including  the Aurora  diode laser and  Centauri Er:YAG laser)  for soft tissue
dental procedures, the Company focuses its marketing efforts on its Aurora diode
laser in this area.
 
    COMPOSITE CURING.  Approximately 48% of  all respondents in a recent  survey
of  dentists conducted by Clinical Research Associates, a dental market research
firm, use composites, an alternate
 
                                       24
<PAGE>
   
material to  amalgams  (gold and  silver)  for cavity  filling.  Composites  are
rapidly replacing amalgams as the material of choice for restoration of cavities
because  they more closely  match the color  of teeth and  because amalgams have
drawn increasing worldwide concern over safety due to the toxic gases which  may
be  released when  the amalgams are  removed from teeth.  Composite fillings are
typically cured  using  a  curing  light which  provides  a  broad  spectrum  of
wavelengths.  The use of an  argon laser for this  application has been shown to
result in a  stronger restoration  than composites cured  by traditional  curing
lights.  The Company's argon lasers can also be  used to cure the resins used in
placing veneers  or  to bond  orthodontic  brackets. The  Company  has  received
clearance to market the MOD argon laser for use in these applications.
    
 
    TEETH  WHITENING.    In  a  recent  survey  conducted  by  Clinical Research
Associates, approximately  79%  of  dentists  surveyed  used  light  accelerated
bleaching  materials with clinical success  for teeth whitening. These materials
are traditionally applied at night over a  six to eight week period to whiten  a
patient's teeth while he or she sleeps. Lasers have been shown to facilitate the
use  of these light sensitive materials  in the dentist's office by accelerating
this process and resulting in an approximate three shade change in less than one
hour. In August  1996, the Company  received clearance to  market its MOD  argon
laser for this application.
 
    HARD TISSUE (CAVITY PREPARATION).  The American Dental Association estimates
that more than 170 million hard tissue restorative procedures are performed each
year in the United States. The Company believes that the use of its dental laser
for  certain of such  procedures could reduce  or eliminate the  need for a high
speed dental  hand drill,  reduce the  need  for anesthesia  and assist  in  the
prevention of dental caries. Potential dental laser applications for hard tissue
procedures  include pit and fissure sealing,  etching, caries removal and cavity
preparation. Based  on user  feedback  from the  Company's clinical  sites,  the
Company  believes  that  the  use  of a  laser  in  dentistry  reduces  the pain
associated with various  traditional procedures performed  with a dental  drill.
Although no lasers are currently approved by the FDA for hard tissue procedures,
the  Company has completed clinical trials  to support its 510(k) application to
the FDA for clearance to market its Centauri Er:YAG laser on teeth. There can be
no assurance, however, that the FDA will not require the Company to submit a PMA
application for this use, or require the Company to conduct additional  clinical
trials or that such product will ever be approved for this use.
 
    CAVITY  PREVENTION.   Studies performed  by an  outside university  on human
extracted teeth have demonstrated that lasers used in conjunction with  fluoride
treatments  can be highly  effective in the prevention  of cavity formation. The
Company is currently  initiating clinical trials  to use its  lasers for  cavity
prevention applications. The Company's clinical trials are at an early stage and
there  can be  no assurance  that the  Company will  obtain clearance  for these
applications.
 
    OPHTHALMIC MARKET
 
    Lasers have been used for the treatment of eye disorders for many years  and
are  widely accepted in  the ophthalmic community. The  original and most widely
accepted use of lasers in ophthalmology has been for posterior capsulotomy.  The
Company  does  not promote  its lasers  for  this market,  which it  believes is
approaching saturation, but instead focuses on intraocular procedures  including
anterior  capsulotomy, cataract  removal, glaucoma  treatment, corneal sculpting
and occuloplastic or cosmetic procedures. The Company has developed the Centauri
Er:YAG laser which is capable of  performing all of these procedures, which  are
typically performed using several different types of medical lasers, although to
date, the Centauri laser has only been cleared for use in anterior capsulotomies
and certain cosmetic procedures.
 
    CATARACT  REMOVAL PROCEDURES.  According to the American Society of Cataract
and  Refractive  Surgeons,   approximately  two   million  cataract   extraction
procedures  are performed  annually in the  United States.  The Company believes
that no lasers have been approved to date for this application, and that  lasers
may  result in less  trauma and inflammation  than traditional surgical methods,
providing more comfort to the patient.  The Company's Centauri Er:YAG laser  has
been  cleared to  market for anterior  capsulotomy, a procedure  which opens the
capsule of the eye prior to the removal
 
                                       25
<PAGE>
of the cataract. The Company is also currently conducting clinical trials on the
Centauri laser for lens emulsification (the removal of the cataract itself),  as
an alternative to phacoemulsification (the breakup of the cataract by ultrasonic
energy).  The  Company  believes  this  patented  technology  for  use  in  lens
emulsification may provide an easier and safer method of cataract removal.
 
    TREATMENT OF GLAUCOMA.  According to  the National Institutes of Health,  in
1995,  approximately three  million people  in the  United States  suffered from
glaucoma, a disease of the  eye characterized by increased intraocular  pressure
within  the eyeball and progressive loss  of vision. Traditionally, glaucoma has
been treated  with drug  therapy.  When drug  therapy is  ineffective,  periodic
invasive surgery may be required. In these cases, lasers may be used to open the
sclera  and relieve pressure in the eye.  This procedure, which must be repeated
periodically, can  be  performed under  local  anesthesia with  a  self  closing
incision  on an outpatient  basis. The Company  is currently conducting clinical
trials to  support  investigational  device  exemption  ("IDE")  submittals  for
clearance  to market its Centauri Er:YAG  laser for this procedure. If clearance
is obtained, as to which there can  be no assurance, the Company's Er:YAG  laser
could  provide  a  viable  alternative  to  the  traditional  invasive  surgical
procedures.
 
    CORNEAL SCULPTING.  Medical Insight, Inc. estimated in 1993 that 170 million
people  in  the   United  States  suffered   from  vision  disorders   including
nearsightedness   (myopia),  farsightedness  (hyperopia)  and  astigmatism.  The
Company believes that  the recent  approval of  excimer lasers  has resulted  in
greater acceptance and recognition of laser refractive surgery in the ophthalmic
market.  Medical  lasers  may  be used  for  corneal  sculpting (photorefractive
keratectomy), a procedure in which the laser is used to sculpt the cornea of the
eye to a desired curvature to correct the myopia, hyperopia or astigmatism.  The
Company  plans to  seek FDA  approval to market  the Centauri  laser for corneal
sculpting and has initiated  animal studies for  this application. No  assurance
can be given, however, that FDA approval will be given for this application.
 
    SURGICAL MARKET
 
    Lasers  have been approved for and are  currently being used in a variety of
surgical   applications    including   orthopedics,    neurosurgery,    urology,
gastroenterology, ophthalmology, cardiology, dermatology, gynecology and plastic
surgery.  Although the Company's products  are cleared to market  in a number of
specialty areas  within  the  surgical  market,  the  Company  has  specifically
targeted  tissue melding  (tissue fusion)  and cosmetic  applications within the
surgical market.
 
    TISSUE MELDING.  The Company believes a significant number of wound  closure
procedures  may  be  addressed  with  surgical  lasers  in  conjunction  with or
independent of traditional  sutures or  staples. The Company  believes that  the
benefits of the use of surgical lasers for tissue melding, as compared to suture
and  staples, include fluid-static seals, immediate  strength of the closure and
reduced surgical  time. The  Company and  its strategic  partner have  conducted
animal  tests to  support IDE  submittals for the  use of  the Company's Polaris
Nd:YAG laser in the areas of arteries,  veins, blood vessels and ducts, and  are
currently  conducting clinical studies for skin and hypospadias. The Company has
also completed clinical trials for vasovasotomy (reversal of vasectomies)  which
demonstrated  a success rate of approximately 89%. The Company is also beginning
Phase I clinical trials for the treatment of hypospadias, the lengthening of the
urethra to the end of the penis in infant boys, in which it is anticipated  that
the  laser's fluid-static seal may  minimize post-surgical complications such as
the leakage of urine which  requires secondary surgical procedures. The  Company
has   clearance  for  Phase  II  clinical  trials  for  skin  closure  following
mastectomies and eyelid surgery at five clinical sites. Artery and vein  melding
is  being  tested in  animals by  the  Company's strategic  partner in  Japan in
preparation for clinical studies.
 
    COSMETIC SURGICAL  PROCEDURES.    The  Company  entered  into  a  Purchasing
Agreement  and a  Share Exchange Agreement  dated December 20,  1995 with Mattan
Corporation, the  parent  corporation  of Medical  Laser  Institute  of  America
("MLIA"),  pursuant to  which the  Company made an  investment in  and formed an
alliance with MLIA. Mattan owns and operates or provides marketing support for a
series of medical laser cosmetic surgery centers, which centers focus on wrinkle
removal, treatment of
 
                                       26
<PAGE>
varicose veins,  acne  scar  removal, tattoo  removal  and  refractive  surgery.
Pursuant to these agreements, Mattan has agreed to purchase all laser equipment,
accessories  and  disposable  laser  products  for  use  in  its  laser  centers
exclusively from the Company until December 31, 2005. To the extent the  Company
is  unable  to provide  a requested  laser to  Mattan, the  Company will  act as
purchasing agent  for Mattan  and purchase  the lasers  from a  third party  for
resale to Mattan. During the 1996 Quarter, sales to Mattan accounted for $90,651
of the Company's revenues. Substantially all of such sales were resales of third
party products.
 
    The Company has regulatory clearance to market its products for a variety of
additional    applications,   including    urology,   orthopedics,   gynecology,
gastroenterology, podiatry, pulmonary  and neurosurgery, among  other areas.  In
areas  where the Company's  technology is not being  fully utilized, the Company
may seek  agreements  to supply  its  products  under private  label  for  other
manufacturers  or may enter  into strategic alliances to  develop and market the
Company's lasers for other applications.
 
BUSINESS STRATEGY
 
    The Company's strategy is to seek to increase its market penetration in  the
dental,  ophthalmic and surgical markets. Key elements of the Company's strategy
include the following:
 
    FOCUS ON  THE OFFICE  AND SURGICAL  CENTER MARKETS.   Recognizing  the  cost
containment environment of the medical industry, the Company intends to focus on
clinical  applications for lasers which may be performed in a surgical center or
medical office.  Management believes  that the  Company's compact  and  portable
lasers  offer cost efficiencies  and can be  used to take  advantage of industry
trends which favor minimally invasive medical procedures.
 
    INCREASE DOMESTIC MARKETING AND ACCEPTANCE OF LASER TECHNOLOGY.  The Company
intends to expand its domestic  marketing organization through additional  sales
representatives  and distributors to target  the dental, ophthalmic and surgical
markets in the United States. The Company also intends to continue to  implement
a  doctor awareness  and education  program to  address the  individual doctor's
training,  practice  management  and  marketing  needs.  The  Company   believes
increased  publicity  and  additional  publications  are  essential  to  educate
dentists, physicians and patients about the clinical benefits of medical lasers.
 
    EMPHASIZE EXPANSION IN INTERNATIONAL MARKETS.   Foreign sales account for  a
substantial  portion of the Company's revenues and the Company intends to devote
additional  resources  to  expand  the  worldwide  marketing  of  its  products,
particularly  in the Pacific Rim and Europe. The Company anticipates substantial
growth opportunity  in these  markets  and will  seek  to enter  into  marketing
arrangements  with  recognized  distributors who  will  aggressively  market and
service the  Company's  products in  each  region. Such  expansion  may  include
potential  acquisitions of businesses which have  a marketing presence in Europe
and the  Pacific Rim.  There  are no  present  negotiations or  agreements  with
respect to any acquisitions, and no assurance may be given that the Company will
be able to identify or consummate any such acquisitions.
 
   
    EXPAND  CLINICAL APPLICATIONS FOR PROPRIETARY LASER TECHNOLOGY.  The Company
manufactures lasers which are  multidisciplinary in their surgical  applications
and multifunctional in the specific procedures for which they have been cleared.
The  Company holds  19 United  States patents  and 13  foreign patents,  and has
pending 13 United States patents and 41 foreign patents. The Company intends  to
expand  its proprietary laser technology by  developing and marketing lasers for
selected additional  applications, which  may  include corneal  sculpting,  hard
tissue  (teeth and bone) cutting, teeth  whitening procedures and tissue melding
applications, subject to FDA approval or clearance.
    
 
    CAPITALIZE ON  DISPOSABLE AFTERMARKET  SALES.   The Company  manufactures  a
variety  of  disposable  fiberoptic  delivery  systems  and  sculpted fiberoptic
probes,  optical  tips,  waveguides  and   catheters  which  are  designed   for
single-patient  use. The  unique design of  the Company's  lasers, including the
patented connecters, encourages the users of the Company's products to  purchase
the  compatible  disposable products  distributed  by the  Company.  The Company
believes that the increasing demand
 
                                       27
<PAGE>
for product  sterility  and cost  containment  will  result in  an  increase  in
disposable  product  sales  and will  provide  a recurring  revenue  stream. The
Company intends to market  these products to existing  customers, as well as  to
hospital administrators on a custom basis for other surgical lasers.
 
    DEVELOP  NEW MARKETS THROUGH STRATEGIC ALLIANCES.   The Company will seek to
establish strategic  alliances  in order  to  expedite  and lower  the  cost  of
developing  and bringing to market new  products in current markets and existing
products in new  markets. The  Company believes a  substantial potential  market
exists for its laser technology and products both inside and outside the dental,
ophthalmic  and  surgical  markets.  Strategic  alliances  could  accelerate the
Company's efforts to expand in several key areas including, but not limited  to,
tissue  melding,  bone  shaping,  removal  of  bone  cement  and  discectomy  in
orthopedics,  photo  dynamic  therapy,   revascularization  of  the  heart   and
interstitial  treatment of the prostate. Pursuant  to this strategy, the Company
entered into an Exclusive  Marketing Agreement dated July  26, 1994 with  Nippon
Shoji  Kaisha, Ltd. ("NSK") to distribute the Company's Polaris Nd:YAG laser for
tissue melding applications in  Japan, China and Taiwan,  subject to receipt  of
regulatory approval.
 
    Although   the  Company  will  continue  to  seek  to  increase  its  market
penetration in  the dental,  opthalmic and  surgical markets,  there can  be  no
assurance  that the foregoing  strategy will be  commercially successful or that
the Company's products will be accepted  by the medical or dental community,  or
that  a significant market for the Company's laser systems will be developed and
sustained.
 
LASER PRODUCTS
 
    The Company's line of portable lasers  are specifically designed for use  in
outpatient  surgical centers and medical offices.  The Company believes that its
lasers are  also  well suited  for  the international  market,  particularly  in
facilities  with many surgical suites where  easy transportation of equipment is
necessary. By  employing  techniques developed  in  the computer  industry,  the
Company  has designed  a laser  system that (i)  is modularly  designed and uses
similar components for  multiple laser  systems thereby  reducing their  overall
cost,  (ii) allows for efficient and inexpensive  repair by replacing a board or
assembly in the field or through the mail, reducing the need for a field service
force, and (iii) can be easily moved from the office to surgical centers because
of its  compact size  and  limited voltage  requirements. The  Company's  Er:YAG
lasers  are currently priced from $35,000 to  $115,000 and its Nd:YAG lasers are
currently priced  from  $25,000  to  $80,000. The  Company's  diode  lasers  are
currently  priced from $20,000 to $30,000, its argon laser is priced from $8,000
to $20,000 and its CO(2) lasers are currently priced from $5,500 to $20,000. The
prices of lasers within these ranges  depend upon each model's power  capability
and the features offered.

(1)  The Company  has made  modifications to certain  of its  products which the
    Company believes do not require the submission of new 510(k)  notifications.
    However,  there  can  be no  assurance  that  the FDA  will  agree  with the
    Company's determinations and  will not  require the  Company to  discontinue
    marketing  one or more of the  modified devices until the modifications have
    been cleared  by the  FDA. There  also can  be no  assurance that  any  such
    clearance  of modifications would be  granted should clearance be necessary.
    See "-- Government Regulation."
 
    CENTAURI ER:YAG LASER
 
    The Company's Centauri Er:YAG laser is a portable Er:YAG pulsed solid  state
laser  which  generates high  frequencies (up  to 30Hz)  at relatively  low peak
power. These high frequencies  allow faster cutting at  lower energies. The  2.9
micron  wavelength of the  Er:YAG is highly  absorbed by water,  producing a cut
similar to the scalpel. The Er:YAG wavelength is delivered through a fiber optic
delivery system  which  enables  the  beams to  be  focused  and  angled.  These
fiberoptic  catheters  are difficult  to produce  and  the Company  has invested
heavily in the technology to develop fibers which can handle adequate power. The
Company has experienced difficulties in  securing a consistent source for  these
fibers  in the past, although it has recently procured two new sources for these
fibers. See "-- Legal Proceedings."
 
    The Company's  Centauri  Er:YAG laser  has  many potential  applications  in
different  medical specialties, including  cutting hard tissue  such as bone and
teeth, which could replace or minimize the use of noisy, high speed dental  hand
drills,  and removing ocular structures  or performing microsurgery with minimal
thermal  damage.  Although  presently  marketed  only  for  soft  tissue  dental
procedures  and anterior capsulotomy, the Centauri  laser also has clearances to
market for  hemostasis (cessation  of bleeding),  excision and  vaporization  of
tissues   in   ophthalmology,   general   surgery,   neurosurgery,  orthopedics,
gastroenterology, urology,  gynecology  and  oral surgery.  See  "--  Government
Regulation."  The  Centauri laser  is  highly effective  in  cataract ophthalmic
procedures because  its  wavelength is  at  the  peak of  the  water  absorption
spectrum  and water comprises greater than 60% of ophthalmic tissues. Therefore,
the Centauri  laser can  emulsify  cataracts, surgically  excise tissue  in  the
treatment  of glaucoma and can precisely remove layers of cornea similarly to an
excimer laser. This system, which currently is cleared for anterior  capsulotomy
and  other  procedures  in  ophthalmology,  is  estimated  to  be  available for
approximately one-third the price of refractive excimer lasers currently on  the
market  and requires substantially  lower maintenance costs  than excimer lasers
(an estimated annual expense of  $10,000 as compared to approximately  $70,000).
In  addition,  the  multiple  application Centauri  Er:YAG  laser  is completely
portable, does  not emit  any toxic  gases or  cause any  potentially  mutagenic
effect which may result from the use of the excimer laser.
 
                                       29
<PAGE>
    The  Company has recently  introduced what it believes  to be the industry's
first fully-integrated Er:YAG  laser system for  ophthalmic procedures. The  new
system  incorporates the Centauri Er:YAG laser and provides the option of either
a bi-manual  or  coaxial,  uni-manual handpiece  to  accommodate  an  individual
physician's   technique.  The  Company  has   also  recently  introduced  a  new
irrigation/ aspiration product for use in conjunction with the Centauri  system,
which  integrates with the  laser in performing  the cataract removal procedure,
and includes  proprietary vacuum  monitoring connectors  that create  a  sterile
aspiration line.
 
    While  animal studies have been encouraging,  there can be no assurance that
the FDA  will  approve the  use  of the  Company's  Centauri laser  for  corneal
sculpting,  or that the laser will work effectively in clinical trials. Clinical
trials are estimated to continue  for two to five  years before approval can  be
sought  in  the  United  States.  There  are  several  patents  pending  on this
technology and  application, although  no  assurances can  be given  that  these
patents will be approved or approved with the current claims.
 
    POLARIS AND PEGASUS ND:YAG LASERS
 
    The  energy of Nd:YAG lasers is absorbed by  blood in tissue and as a result
these systems are the preferred lasers to limit bleeding during surgery and  for
procedures  requiring  fiberoptic delivery,  such  as laparoscopic  surgery. The
Nd:YAG fiberoptic delivery system allows the surgeon to perform surgery  through
small  incisions, providing minimally  invasive surgery to  patients and usually
reducing treatment costs and the length of hospital stays.
 
    The Company manufactures  a variety  of continuous wave  solid state  Nd:YAG
lasers  which  are  designed  for  use in  dentistry  and  a  number  of medical
specialties. The Company  received its  first clearance to  market a  continuous
wave  Nd:YAG laser system  for dental (soft  tissue) applications and introduced
its 20  watt dental  Pegasus Nd:YAG  laser in  February 1992.  The Company  also
manufactures  40, 60 and 100 watt Pegasus  Nd:YAG lasers which have clearance to
market for  various applications  and procedures  in general  surgery,  urology,
gastrointestinal  procedures, pulmonary procedures, gastroenterology, gynecology
and ophthalmology.
 
    These lasers  also  utilize the  Company's  disposable and  reusable  unique
TouchTIPS,  AngleTIPS and  sculptured fibers.  By using  the Pegasus  laser with
TouchTIPS, the surgeon  is allowed direct  contact with tissue  and the  tactile
feeling  of the scalpel or other surgical instruments. The Company believes that
the availability of  these technologies  permits the  use of  lower power  laser
systems (20 watt in dental, 40-60 watt in surgery).
 
    In  December 1993, the Company entered into an Asset Purchase Agreement with
Proclosure  pursuant  to  which  the   Company  acquired  from  Proclosure   the
proprietary  rights,  including several  patents,  to manufacture  and  sell the
Polaris laser, a 1.32 micron Nd:YAG  laser (except in Japan, China and  Taiwan),
together with specialized software and delivery systems, for tissue melding. The
Company  is  developing the  Polaris laser  for use  in cosmetic  skin closures,
vascular surgeries and minimally invasive surgical procedures normally performed
with sutures  and staples.  Although the  use of  the Polaris  laser for  tissue
melding is still in the development stage, and no clearance for this application
has  been received,  the Company  believes that  tissue melding  offers clinical
advantages over traditional sutures and staples.
 
    AURORA DIODE LASER
 
    The Aurora diode laser  is the Company's first  semiconductor laser and,  to
the  Company's knowledge, is  the first truly portable  diode laser designed for
dentistry. The  Aurora  diode laser  replaces  the  20 watt  Pegasus  laser  for
periodontal  procedures, and is one-fourth the size  and one-half of the cost of
that system. The diode wavelength is  absorbed by blood in pigmentation and  has
been   cleared  for  use  in  multiple  specialties  such  as  general  surgery,
ophthalmology,  urology  and  plastic  surgery.  The  Aurora  laser,  which  was
introduced  for soft tissue dental applications in February 1996, is designed to
utilize  the  Nd:YAG  delivery  systems,  including  TouchTIPS,  AngleTIPS   and
sculptured  fibers, for soft tissue surgery with minimal bleeding or anesthesia.
This dental laser can also be used to treat early
 
                                       30
<PAGE>
stage gum  disease,  postponing  or  in some  cases  eliminating  the  need  for
periodontal  surgery and providing the opportunity for overall cost savings. The
Company believes the Aurora laser  compares favorably with competitive  products
including pulsed Nd:YAG lasers, which cannot produce the required laser settings
for use with TouchTIPs, or in the new technique for the treatment of periodontal
disease,  as well  as with  CO(2) lasers  (which cannot  be delivered  through a
fiber), and argon lasers  (which tend to  be slower in  cutting and may  produce
charring).
 
    ARAGO AND MOD ARGON LASERS
 
    The Arago and the MOD are argon gas lasers which have been cleared to market
in  dentistry to accelerate the composite curing process. Composites are rapidly
replacing amalgams  (gold  and  silver)  as  the  material  of  choice  for  the
restoration  of cavities. The argon  wavelength penetrates through the composite
and has been shown to result in a stronger restoration than composites cured  by
traditional  curing lights. The Company's argon lasers  can also be used to cure
the resins used in placing veneers or bonding orthodontic brackets.
 
    The argon laser can also be used to enhance teeth whitening procedures using
light activated bleaching  materials which  have traditionally  been applied  at
night  over a six to eight week period. Lasers have been shown to facilitate the
use of these light activated products in a dentist's office by accelerating this
process and resulting  in an  approximate three shade  change in  less than  one
hour.  In August 1996,  the Company received  clearance to market  its MOD argon
laser for this application. No assurance may be given, however, that the use  of
the  argon laser for teeth  whitening will become a  widely accepted practice in
the dental industry. The Company plans to bundle its lasers with light activated
whitening materials and co-market these products with the manufacturers of these
materials.
 
    The MOD argon  laser is  manufactured by the  Company pursuant  to a  letter
agreement dated August 24, 1996 with International Biolaser Corporation ("IBC").
Pursuant  to this agreement, the Company has guaranteed certain debt of IBC to a
third party in the amount of  approximately $201,000, plus future interest.  The
Company  has also  entered into  a letter agreement  dated August  14, 1996 with
Lasermed, Inc., pursuant to which the Company maintains the non-exclusive  right
to  purchase a  limited number of  the portable lightweight  Arago argon lasers.
This agreement terminates in November 1996. The Company will seek to extend this
agreement or, if no extension  can be obtained on  acceptable terms, to find  an
alternative  source for the  argon laser, the Company's  inability to extend the
agreement or find a suitable replacement  product could have a material  adverse
effect on the Company's business, results of operations and financial condition.
 
    ALTAIR CO(2) LASERS
 
    The  CO(2) laser was the first available  and the early standard in surgical
laser applications. The 10.6 micron wavelength  generated by the CO(2) laser  is
absorbed  by water in  tissue. The CO(2)  laser acts like  a surgical scalpel to
vaporize tissue with minimal blood loss  and scarring. The risk of infection  is
reduced  by  thermal sealing  of  blood and  lymphatic  vessels in  the adjacent
tissues. The characteristics of the CO(2) laser have provided a wide variety  of
medical  specialists  a modality  of  treatment that  has  significantly changed
conventional invasive surgery in a number of clinical specialties.
 
    The Company's hand-held  10 and 20  watt CO(2) lasers  acquired from  Pfizer
Laser  are  marketed primarily  for office  use by  podiatrists, dermatologists,
orthopedists, dentists and gynecologists. The  laser weighs less than 40  pounds
and  packs in  a suitcase. The  Company and Pfizer  Laser have sold  a number of
these lasers and the Company continues to provide service and support for  these
products.  To expand its CO(2)  laser product line, the  Company has designed 35
watt and 65 watt Altair CO(2) lasers for hospital based surgeries. These  lasers
are  portable,  and  laser energy  may  be  delivered through  a  waveguide arm,
reusable or  disposable  handpieces  or  more  maneuverable  flexible  waveguide
delivery systems.

DELIVERY SYSTEMS AND DISPOSABLE PRODUCTS
 
    An integral part of any laser system is the means of delivering laser energy
to  the  target  tissue. Delivery  systems  commonly employed  in  laser surgery
include flexible fiberoptics, waveguides, articulated arms and
micromanipulators.  The  Company's  proprietary  delivery  systems  control  the
relative  proportions of acoustic, thermal and  optical energy applied to tissue
resulting in enhanced cutting efforts. Flexible fibers are a preferred method of
delivery for most clinical  procedures, but until  recently were only  available
for  Nd:YAG and argon lasers.  The end of a  fiber may be shaped  or used with a
detachable tip to control the mechanism  of laser/tissue interaction, to give  a
tactile  feel, to provide certain  mechanical effects and to  angle or focus the
laser beam. The  Company has also  been granted a  perpetual paid-up license  to
manufacture,  use and sell flexible waveguides  to deliver CO(2) energy pursuant
to the  Assignment and  Modification Agreement  dated July  26, 1991  among  the
Company, Pfizer HPG and Medical Laser Technologies Limited.
 
    While  each laser system marketed by the  Company consists of a laser and an
integral fiber, these fibers and other  products, such as tubing sets, are  used
by  surgeons on a disposable or limited reuse basis for each clinical procedure.
The  Company   believes  that   expansion  into   this  market   could   provide
 
                                       32
<PAGE>
it  with  a recurring  revenue  stream. The  Company  manufactures a  variety of
fiberoptic delivery systems, sculpted fiberoptic probes, optical tips (AngleTIPS
and TouchTIPS), waveguides and catheters  which are designed for  single-patient
use.  The patented connectors and need for product sterility encourage the users
of the Company's lasers to purchase only products which are compatible with this
system. The Company believes  it can sell  these products on  a custom basis  to
hospital  administrators  for  other  surgical laser  systems  at  a significant
discount to  competitors'  published  prices, while  maintaining  gross  margins
through  vertical integration  and the extensive  use of molds  and tooling. The
Company also  assembles  and  distributes  a full  line  of  laser  accessories,
including glasses, goggles, laser signs and smoke evacuators.
 
    During  fiscal 1994, 1995 and 1996, sales of laser accessories accounted for
approximately 10%, 19% and 14%, respectively, of the Company's revenues.
 
MARKETING, SALES AND SERVICE
 
    MARKETING AND SALES
 
    The Company markets its products to  the dental market in the United  States
directly to dentists and periodontists through its direct sales force consisting
of   five  area  sales  managers  and  its  recently  expanded  distributor  and
manufacturer's representative network  consisting of  more than  25 people.  The
Company markets its products primarily through conventions, educational courses,
direct  mail, telemarketing and  other dental training  programs. In March 1994,
the Company entered into a sales and marketing arrangement for its dental lasers
with  Burkhart  Dental  Supply  Company,   a  member  of  the  American   Dental
Cooperative,  Inc., which is one of the largest distributors of dental equipment
and supplies in the United States. This agreement is terminable by either  party
at any time. If this strategic alliance is successful, the Company believes this
relationship  may  be  expanded to  the  other  members of  the  American Dental
Cooperative, Inc. which markets dental products  to a significant number of  the
approximately 129,000 practicing dentists in the United States. Such alliance is
expected  to assist the Company if the  Company receives clearance to market the
Centauri laser for hard tissue applications.
 
    Through an active  program of  educational courses  and preceptorships,  the
Company  has  trained  dentists in  ten  countries  during the  past  year using
industry recognized dentists and periodontists. In the past two years, more than
20 dental papers  have been  presented by the  Company or  clinicians using  the
Company's products.
 
    The Company markets its products in the ophthalmic market through two direct
sales managers who focus on sales to key ophthalmologists worldwide. The Company
has  entered into distribution agreements with distributors in nine countries in
preparation for market introduction of the Centauri laser during calendar  1996.
The  Company grants exclusive  distribution rights in  select territories to its
distributors who must maintain certain distribution minimums in order to  retain
their  exclusive rights. The Company plans  to expand its ophthalmic sales force
both by  enlarging  its  domestic  sales force,  either  internally  or  through
acquisition, and by acquiring or engaging additional international manufacturing
representatives.
 
    In  the surgical market, the Company  intends to form strategic alliances in
any specialty area where the partner  has an established presence in the  market
selling  to either the physician  or the hospital. The  Company has entered into
such a strategic alliance with NSK, one  of the leading suppliers of sutures  in
the  Pacific  Rim,  pursuant to  an  Exclusive Marketing  Agreement.  Under this
agreement, Proclosure  granted  to NSK,  in  exchange  for a  license  fee,  the
exclusive  rights to  market and distribute  the Polaris Nd:YAG  laser in Japan,
China and Taiwan. In addition, under this agreement, the Company granted to  NSK
an  option to manufacture the  Polaris, which if exercised  would require NSK to
pay the Company  a $1.5 million  fee and  royalties. NSK has  not yet  indicated
whether it intends to manufacture these products. There can be no assurance that
the Company will receive any payments under this agreement.
 
                                       33
<PAGE>
    Sales  in fiscal 1996 to one  customer, Rockford Industries, Inc., a leasing
company, accounted for 10% of  the Company's net sales  for that year. Sales  in
fiscal  1995 to LaserSight Centers, Inc.  accounted for approximately 11% of the
Company's net sales for that year.
 
    CUSTOMER SERVICE AND SUPPORT
 
    The Company is seeking to create a  group of loyal customers by focusing  on
customer  service,  quality  and  reliability. In  addition  to  its educational
courses, the Company performs a complete  installation of its lasers and  trains
the  customers'  staff in  its  proper use.  Educational  videos and  papers are
available upon request. The  Company conducts service  training courses for  the
representatives of its distributors. Prior to shipping, every laser is subjected
to  an extensive battery  of quality control  tests. The Company  provides a one
year warranty  with all  lasers  and extended  warranties  are available  at  an
additional  cost. The Company generally provides service within one business day
to all of its customers in the United  States. An owner is either sent a  loaner
laser  by  overnight carrier  or a  service representative  visits the  owner to
repair the  unit.  International  service  is provided  either  by  the  foreign
distributor  or  by  return  of  the  laser  to  the  Company.  The  Company has
experienced and may continue to experience difficulties in providing prompt  and
cost-effective service of its medical lasers in foreign countries.
 
COMPETITION
 
    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 or therapies, some of which include medical lasers manufactured  by
competitors.  In the dental  market, the Company  competes primarily with dental
drills, traditional  curing lights  and other  existing technologies,  and to  a
lesser  extent  competitors'  CO(2), argon,  Er:YAG  and Nd:YAG  lasers.  In the
ophthalmic market, the Company  is subject to  competition principally from  the
(i)  traditional surgical  treatments using  a needle  to tear  a circle  in the
anterior capsule, (ii) phacoemulsification, an  ultrasound device used to  break
up  cataracts in cataract removal procedures,  (iii) corrective eyewear (such as
eyeglasses and contact lenses) and surgical treatments for refractive  disorders
such as photorefractive keratectomy which is typically performed with an excimer
laser  and radial keratotomy  which is performed  with a scalpel,  and (vi) drug
therapy or surgical treatment of glaucoma. In the surgical market, wound closure
procedures are  usually performed  using sutures  and staples,  and  traditional
cosmetic  surgical procedures may be performed with  a scalpel or a CO(2) laser.
The Company  believes that  for many  applications its  proprietary methods  and
fiberoptic delivery systems provide clinical benefits over other currently known
technologies and competitors' laser products.
 
    The  medical  laser  industry  in  particular  is  also  subject  to intense
competition and  rapid technological  changes. The  Company believes  there  are
approximately 30 competitors in different sectors of the medical laser industry.
The Company believes that the principal competitive factors in the medical laser
industry  are the products' technological capabilities, proven clinical ability,
patent protection, price and scope of  regulatory approval, as well as  industry
expert  endorsements.  Many  conventional laser  systems  target  one particular
application, while  the  Company's  Er:YAG  system is  designed  to  perform  in
multiple  therapeutic  applications.  The  Company's  self-contained  units  are
significantly smaller than  competitive surgical models,  have internal  cooling
devices  and are powered primarily by dedicated readily available 110 volt lines
instead of the  220 volt lines  used by  most surgical solid  state lasers.  The
specialized  menu-driven system software  utilized in the  Company's lasers also
enhances safety and ease of use of the lasers.
 
    The Company  believes  that  its ability  to  compete  successfully  against
traditional  treatments, competitive  laser systems  and treatments  that may be
developed in  the future  will depend  on  its ability  to create  and  maintain
advanced  technology, develop  proprietary products,  obtain required regulatory
approvals and  clearances  for  its  products,  attract  and  retain  scientific
personnel,  obtain patent or  other proprietary protection  for its products and
technologies, and manufacture and successfully  market products either alone  or
through other parties. Certain of the Company's competitors
 
                                       34
<PAGE>
have substantially greater financial, technical and marketing resources than the
Company.  There can  be no  assurance that  such competition  will not adversely
affect the  Company's  results of  operations  or  its ability  to  maintain  or
increase market share.
 
RESEARCH AND DEVELOPMENT
 
    During  the last two fiscal years, the  Company has invested an aggregate of
approximately $2.5 million in research  and development programs. The  Company's
research   and  development  programs  have  capitalized  on  the  research  and
development activities conducted by Pfizer Laser wherein that company identified
key military  and  aerospace  technologies and  adapted  these  technologies  to
portable,  efficient, solid-state  laser products  that were  modular in nature.
This investment in research and development  has resulted in the development  of
19  models  of lasers,  more than  1,000  types of  custom delivery  systems and
approximately 20 types of  surgical tips and  accessories. Approximately 41%  of
the  Company's net sales  for fiscal 1996  were derived from  sales of three new
lasers introduced during the last six months  of that year. Five more lasers  or
related  products  are scheduled  for introduction  in  fiscal 1997,  subject to
receipt of clearance  to market  such products, for  which no  assurance may  be
given.
 
   
    In  order to maintain its technological advantage, the Company must continue
to invest in new product development.  The Company seeks to augment its  funding
of  research and  development through  government grants.  The Company  has been
awarded a Phase II SBIR grant  of $750,000, of which approximately $698,000  has
been  drawn to date  and the remainder of  which can be drawn  over the next six
months  to  fund  additional  research  and  clinical  trials  regarding   laser
emulsification  of  cataracts. The  Company  has also  applied  for new  Phase I
research  grants  related  to   dentistry,  orthopedics,  tissue  welding,   and
ophthalmology. No assurance can be given that the Company will be awarded any of
these potential government grants.
    
 
    The  Company's  current  research  is  focused  on  expanding  the  clinical
applications of its  existing products, reducing  the size and  cost of  current
laser  systems, developing custom delivery systems and developing new innovative
products. The Company's in-house research  and development efforts have  focused
on  the  development  of  a  systems approach  to  medical  laser  products with
proprietary delivery systems designed to allow the laser to interact with tissue
by a number of different mechanisms  (e.g., acoustic, ablative and thermal)  for
unique  laser/tissue  effects.  These  disposable  fiberoptic  delivery systems,
developed  specifically  for  niche   surgical  applications,  demonstrate   the
principal  focus  of the  Company's research  efforts.  Examples of  patented or
patent  pending  products  resulting   from  these  research  efforts   include:
TouchTIPS, AngleTIPS, Er:YAG fiberoptics and CO(2) waveguides. Clinical research
has also yielded several new surgical procedures.
 
PATENTS AND PATENT APPLICATIONS
 
   
    Patent  protection is an important part  of the Company's business strategy,
and the Company's success depends, in  part, on its ability to maintain  patents
and  trade secret protection and on its ability to operate without infringing on
the rights  of third  parties. The  Company  has sought  to protect  its  unique
technologies and clinical advances through the use of the patent process. Patent
applications  filed in the  United States are frequently  also filed in selected
foreign countries. The  Company focuses  its efforts  on filing  only for  those
patents  which the Company believes will provide it with key defensible features
instead of filing for all potential minor device features. The Company holds  19
U.S.  patents and  has other patent  applications pending in  the United States,
including divisional applications.  In addition,  the Company  holds 13  foreign
patents  including  two  utility  model patents  and  has  other  foreign patent
applications pending. No  assurance can  be given  that any  additional U.S.  or
foreign  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. The Company also has a nonexclusive license to a number
of  basic laser technologies  which are commonly  licensed on such  basis in the
laser industry.
    
 
    The Company's success will  depend in part on  its ability to obtain  patent
protection  for its  products and  processes, to  preserve trade  secrets and to
operate without infringing the rights of
 
                                       35
<PAGE>
others. 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 for its  Er:YAG laser. In the  past, the Company has  received
allegations that certain of the Company's laser products infringe other patents.
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 in  which the Company may become a  party
could subject the Company to significant legal judgments or 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 on  unpatented trade
secrets, and  no assurance  can  be given  that  others will  not  independently
develop or otherwise acquire substantially equivalent trade secrets.
 
GOVERNMENT REGULATION
 
    FDA REGULATION
 
    The  lasers that  are manufactured by  the Company are  regulated as medical
devices by the  FDA under  the FDC  Act. Satisfaction  of applicable  regulatory
requirements  may take several  years and requirements  vary substantially based
upon the type, complexity and  novelty of such devices  as well as the  clinical
procedure.  Pursuant to the FDC Act  and the regulations promulgated thereunder,
the FDA regulates the preclinical  and clinical testing, manufacture,  labeling,
distribution,  and promotion  of medical devices.  Noncompliance with applicable
requirements can  result  in  fines, injunctions,  civil  penalties,  recall  or
seizure  of  products,  total or  partial  suspension of  production,  denial or
withdrawal of premarket  clearance or approval  for devices, recommendations  by
the  FDA that the Company not be allowed to enter into government contracts, and
criminal prosecution. The FDA also has the authority to request recall,  repair,
replacement  or refund of the cost of  any device manufactured or distributed by
the Company.
 
    The FDA classifies medical  devices in commercial  distribution into one  of
three  classes: Class I, II or III. This classification is based on the controls
the FDA deems  necessary to reasonably  ensure the safety  and effectiveness  of
medical devices. Class I devices are subject to general control (E.G., labeling,
premarket  notification and adherance to GMPs)  and Class II devices are subject
to  general  and  special  controls  (E.G.,  performance  standards,  postmarket
surveillance,  patient  registries, and  FDA  guidelines). Generally,  Class III
devices are those  which must receive  premarket approval by  the FDA to  ensure
their  safety  and  effectiveness  (E.G.,  life-sustaining,  life-supporting and
implantable  devices,  or  new  devices  which   have  been  found  not  to   be
substantially  equivalent  to legally  marketed  devices). Lasers  typically are
classified as Class II devices, but the FDA may classify certain indications  or
technologies into Class III and require a PMA.
 
    If  a manufacturer or distributor  of a medical device  can establish that a
proposed device is "substantially equivalent" to  a legally marketed Class I  or
Class  II medical device or to a pre-1976 Class III medical device for which the
FDA has not  called for  a PMA,  the manufacturer  or distributor  may seek  FDA
clearance for the device by filing a Section 510(k) premarket notification. If a
manufacturer or distributor of a medical device cannot establish that a proposed
device  is  substantially equivalent  to  another legally  marketed  device, the
manufacturer or  distributor  will  have  to seek  premarket  approval  for  the
proposed  device. A 510(k) notification and the claim of substantial equivalence
will likely  have  to be  supported  by various  types  of data  and  materials,
possibly  including test results or the results of clinical studies in humans. A
PMA would have  to be submitted  and be supported  by extensive data,  including
preclinical    and   clinical   study   data,    to   prove   the   safety   and
 
                                       36
<PAGE>
effectiveness  of  the  device. There  can  be  no assurance  that  some  of the
Company's products will  not require the  more rigorous and  time consuming  PMA
approval,  including laser uses for vasovasotomy or other tissue melding, dental
hard  tissue,  cavity  prevention,   cosmetic  surgery,  sclerostomy  and   lens
emulsification, among others.
 
    If  human clinical studies of a proposed  device are required, whether for a
510(k) or a PMA, and the device presents a "significant risk," the  manufacturer
or  the distributor of the devices will have to file an IDE application with the
FDA prior  to commencing  human clinical  trials. The  IDE application  must  be
supported  by data,  typically including  the results  of animal  and mechanical
laboratory testing. If the  IDE application is  approved by the  FDA and one  or
more appropriate Institutional Review Boards ("IRBs"), human clinical trials may
begin  at a specific number  of investigational sites with  a specific number of
patients, as approved by the FDA. Submission  of an IDE does not give  assurance
that  FDA will approve the IDE and, if it is approved, there can be no assurance
that the FDA will determine that the data derived from these studies support the
safety and  efficacy of  the  device or  warrant  the continuation  of  clinical
studies.  Sponsors of clinical studies are permitted to charge for those devices
distributed in  the course  of the  study provided  such compensation  does  not
exceed recovery of the costs of manufacture, research, development and handling.
Clinical  studies of nonsignificant risk devices  may be performed without prior
FDA approval, but  various regulatory  requirements still  apply, including  the
requirement for approval by an IRB, conduct of the study according to applicable
portions  of the IDE regulations,  and prohibitions against commercialization of
an investigational device.
 
    The manufacturer or  distributor may  not place the  device into  interstate
commerce  until an order is  issued by the FDA  granting premarket clearance for
the device. The FDA  has no specific time  limit by which it  must respond to  a
510(k) premarket notification. The FDA has recently been requiring more rigorous
demonstration of substantial equivalence in connection with 510(k) notifications
and  the review time can take four to 12 months or longer for a 510(k). If a PMA
submission is filed, the FDA has by statute 180 days to review it; however,  the
review  time  is  often  extended  significantly  by  the  FDA  asking  for more
information or clarification of information already provided in the  submission.
During   the  review  period,  an  advisory  committee  may  also  evaluate  the
application and provide  recommendations to  the FDA  as to  whether the  device
should be approved. In addition, the FDA will inspect the manufacturing facility
to  ensure compliance  with the  FDA's good  manufacturing practice requirements
prior to approval of a PMA.
 
    Devices are  cleared by  510(k) or  approved by  PMA only  for the  specific
intended  uses claimed in the submission and  agreed to by the FDA. Labeling and
promotional activities are also subject to  scrutiny by the FDA and, in  certain
instances,  by the Federal Trade Commission.  Marketing or promotion of products
for medical applications  other than those  that are cleared  or approved  could
lead to enforcement action by the FDA.
 
    There  can be no assurance that the Company will be able to obtain necessary
regulatory approvals or clearances for its products on a timely basis or at all,
and delays in receipt of or failure to receive such approvals or clearances, the
loss of previously received approvals or clearances, limitations on intended use
imposed as a  condition of such  approvals or clearances,  or failure to  comply
with  existing or future  regulatory requirements would  have a material adverse
effect on the Company's business, financial condition and results of operations.
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.
 
                                       37
<PAGE>
    REGULATORY STATUS OF PRODUCTS
 
   
    The Company has received 510(k) clearance to market the following lasers  in
an  aggregate of more  than 100 specialty  areas: CO(2) (four  models: 10W, 20W,
35W, 65W); Nd:YAG (four models: 20W, 40W, 60W, 100W); Ho:YAG (one model); Er:YAG
(two models); 1.32m  Nd:YAG (two models:  15W, 25W); .532m  Nd:YAG (one  model);
Argon  (two models); diode  (four models); Nd:YAG/Er:YAG  combination laser (one
model). Each of  these lasers has  clearances in multiple  specialty areas.  The
Company  also has received 510(k) clearance to market sculptured fibers, contact
tip fibers, bare fibers, TouchTIPS, AngleTIPS and focusing tips for all  cleared
wavelengths  of the Company's  lasers as well  as argon lasers.  If a device for
which the Company has already received 510(k) premarket clearance is changed  or
modified in design, components, method of manufacture or intended use, such that
the safety or effectiveness of the device could be significantly affected, a new
510(k)  premarket notification  is required  before the  modified device  can be
marketed in the United States. The Company has made modifications to certain  of
its  products which the  Company believes do  not require the  submission of new
510(k) notifications. However, there can be no assurance that the FDA will agree
with the Company's  determinations and  not require the  Company to  discontinue
marketing  one or more of  the modified devices until  they have been cleared by
the FDA. There can also be no assurance that any such clearance of modifications
would be granted should it become necessary.
    
 
    The Company currently is conducting preclinical animal studies and  clinical
trials,  both under approved IDEs and  as nonsignificant risk studies. There can
be no  assurance that  the results  of any  of these  clinical studies  will  be
successful  or that the FDA  will not require the  Company to discontinue any of
these studies in the interest of the  public health or due to any violations  of
the  FDA's IDE  regulations. There  can be  no assurance  that the  Company will
receive approval from the FDA to conduct any of the significant risk studies for
which the Company seeks IDE approval, or that the FDA will not disagree with the
Company's determination  that  any  of its  studies  are  "nonsignificant  risk"
studies  and require the Company  to obtain approval of  an IDE before the study
can continue.
 
    ADDITIONAL REGULATORY REQUIREMENTS
 
    Any products manufactured or distributed by the Company pursuant to a 510(k)
premarket clearance notification or PMA are or will be subject to pervasive  and
continuing  regulation by  the FDA.  The FDC  Act also  requires the  Company to
manufacture its products  in registered  establishments and  in accordance  with
cGMP regulations, which include testing, control and documentation requirements.
The  Company must also comply with Medical Device Reporting ("MDR") requirements
that a firm report to the FDA any incident in which its product may have  caused
or  contributed  to  a  death  or  serious  injury,  or  in  which  its  product
malfunctioned and, if the malfunction were to recur, would be likely to cause or
contribute to a death or serious injury. The Company's facilities in the  United
States  are subject  to periodic  inspections by  the FDA.  The FDA  may require
postmarketing surveillance with respect to the Company's products. The export of
medical devices is also subject to regulation in certain instances.
 
    All lasers manufactured by the Company are subject to the Radiation  Control
for   Health  and  Safety  Act  administered  by  the  Center  for  Devices  and
Radiological Health of the FDA. The law requires laser manufacturers to file new
product and annual reports and to maintain quality control, product testing  and
sales  records, to incorporate  certain design and  operating features in lasers
sold to  end  users pursuant  to  a performance  standard,  and to  comply  with
labeling  and certification requirements. Various warning labels must be affixed
to the  laser, depending  on the  class  of the  product under  the  performance
standard.
 
    In  addition, the use of the Company's  products may be regulated by various
state agencies. For instance, the Company  is required to register as a  medical
device manufacturer with certain state agencies. In addition to being subject to
inspection by the FDA, the Company also will be routinely inspected by the State
of California for compliance with cGMP regulations and other requirements.
 
    Although  the Company believes that it  currently complies and will continue
to comply with the applicable regulations regarding the manufacture and sale  of
medical devices, such regulations are
 
                                       38
<PAGE>
always  subject to change and  depend heavily on administrative interpretations.
There can  be no  assurance  that future  changes  in law,  regulations,  review
guidelines  or  administrative interpretations  by the  FDA or  other regulatory
bodies,  with  possible  retroactive  effect,  will  not  adversely  affect  the
Company's  business, financial condition and  results of operations. In addition
to the foregoing, the  Company is subject to  numerous federal, state and  local
laws  relating  to  such  matters  as  safe  working  conditions,  manufacturing
practices,  environmental  protection,  fire  hazard  control  and  disposal  of
hazardous  or potentially hazardous  substances. There can  be no assurance that
the Company will not be required to incur significant costs to comply with  such
laws  and regulations in the  future, or that such  laws or regulations will not
have a material adverse effect upon the Company's ability to conduct business.
 
    Furthermore, the introduction of the Company's products in foreign countries
may require obtaining foreign regulatory  clearances, and additional safety  and
effectiveness  standards are  required in  certain other  countries. The Company
believes that  only  a  limited  number  of  foreign  countries  currently  have
extensive  regulatory requirements.  These countries include  the European Union
countries, France,  Germany, Canada,  Mexico and  Japan. Domestic  manufacturing
locations  of American  companies doing  business in  certain foreign countries,
including European  Union countries,  may  be subject  to inspection.  The  time
required  for regulatory  approval in  foreign countries  varies and  can take a
number of years. During the  period in which the  Company will be attempting  to
obtain  the necessary  regulatory approvals, the  Company expects  to market its
products on  a limited  basis in  certain other  countries that  do not  require
regulatory  approval. There can be no assurance that the Company's products will
be cleared or approved by the FDA or other governmental agencies for  additional
applications  in the United States or in  other countries or that countries that
do not now  require regulatory approval  will not require  such approval in  the
future.
 
MANUFACTURING AND MATERIALS
 
    Manufacturing  consists  of component  assembly  and systems  integration of
electronic, mechanical and optical components and modules. The Company's product
costs are principally related to the  purchase of raw materials while labor  and
overhead  have been reduced due  to the use of  customized tooling and automated
test systems.  The Company  believes that  these manufacturing  systems  improve
quality  and manufacturing reliability resulting  in lower overall manufacturing
costs, and  that these  systems  will allow  the  Company to  expand  production
rapidly.
 
    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.
While multiple sources of supply exist for most critical components used in  the
laser  and fiberoptic delivery  systems, the disruption  or termination of these
sources could  have a  material adverse  effect on  the Company's  business  and
results  of operations. Vendor  delays or quality problems  could also result in
production delays of up to six months as several components have long production
lead times. These long lead times, as well as the need for demonstration  units,
require  a significant portion of working  capital to fund inventory growth. The
Company has in the past experienced and may continue to experience shortages  in
raw  materials  and  certain  supplies.  See  "Risk  Factors  --  Dependence  on
Suppliers."
 
    The Company owns the molds used to produce certain proprietary parts of  its
laser products and owns the software used in the operation of its laser systems.
The  Company designs and assembles its own fiberoptic delivery systems and laser
accessory equipment such as laser carts, smoke evacuation devices and associated
disposable supplies. The Company believes  that its manufacturing practices  are
in accordance with cGMP regulations.
 
PRODUCT LIABILITY AND INSURANCE
 
    Since  the Company's products are intended for use in the treatment of human
medical conditions,  the Company  is  subject to  an  inherent risk  of  product
liability  and other liability  claims which may  involve significant claims and
defense costs.  The  Company  currently has  product  liability  insurance  with
coverage limits of $5.0 million per occurrence and $5.0 million in the aggregate
per year. Product
 
                                       39
<PAGE>
liability insurance is expensive and subject to various coverage exclusions, and
in  the future may not be available  in acceptable amounts, on acceptable terms,
or at all. Although the Company does not have any outstanding product  liability
claims,  in the event the  Company were to be  held liable for damages exceeding
the limits of its insurance  coverage or outside of  the scope of its  coverage,
the  business  and results  of  operations of  the  Company could  be materially
adversely  affected.  The  Company's  reputation  and  business  could  also  be
adversely  affected by  product liability claims,  regardless of  their merit or
eventual outcome.
 
FACILITIES
 
    The Company  leases approximately  28,000  square feet  in one  facility  in
Irvine,  California pursuant  to a  lease which  expires in  December 2000. This
facility  contains  the   Company's  executive  offices,   service  center   and
manufacturing  space.  The Company  is required  to  lease an  additional 13,000
square feet in the same facility commencing in January 1999, or on such  earlier
date  that the adjoining  tenant's lease terminates.  While the Company believes
that its manufacturing and administrative facilities are adequate to satisfy the
Company's needs through  at least 2000,  it may need  to lease additional  clean
room facilities in the future.
 
EMPLOYEES
 
   
    As  of October  14, 1996, the  Company employed  41 people, two  of whom are
employed on a  part-time basis.  None of these  employees are  represented by  a
union. Eight employees perform sales, marketing and customer support activities.
The   remaining  employees  perform  manufacturing,  financial,  administration,
regulatory, research and development and quality control activities. The Company
believes that its relationship with its employees is good.
    
 
LEGAL PROCEEDINGS
 
    In March 1994, the Company instituted litigation in the U.S. District Court,
Central District of California, against Infrared Fiber Systems, Inc., a Delaware
corporation ("IFS") which contracted to supply optical fiber to the Company  for
the  Company's Er:YAG  laser. Two  of IFS's  senior officers  are also  named as
defendants. The Company's complaint in this  matter alleges that IFS and two  of
its  officers made misrepresentations  to the Company and  that IFS breached its
agreement to supply fibers and certain warranties concerning the quality of  the
fiber to be provided. The Company is seeking damages and an injunction requiring
IFS to subcontract the production of optical fiber to a third party, as provided
in  the supply agreement. In April 1994, IFS filed a general denial and a cross-
complaint against  the  Company  alleging breach  of  contract  and  intentional
interference  with prospective economic  advantage, seeking compensatory damages
"in excess of $500,000,"  punitive damages and a  judicial declaration that  the
contract  has  been terminated  and that  IFS is  free to  market its  fibers to
others. In September  1996, IFS filed  a new cross-complaint  alleging the  same
causes  of action and seeking substantially the same relief in the Orange County
California Superior Court.  The Company has  filed an answer  to the  complaint,
denying the allegations and asserting several affirmative defenses.
 
    IFS  has agreed to license certain  fiber technologies, to which the Company
claims exclusive license rights, to Coherent, Inc. ("Coherent"), a competitor of
the Company. Coherent  joined the  above federal  litigation on  behalf of  IFS,
seeking  a declaration that IFS  had the legal right  to enter into this license
and supply the fiber  covered by that agreement,  and then subsequently filed  a
new  complaint in  the Orange County  California Superior  Court for declaratory
relief, seeking an order that the Company's original agreement with IFS  applies
only  to  a  specific type  of  optical  fiber. The  Company  has  answered this
complaint.
 
    In May 1995, the  Company instituted litigation  concerning this dispute  in
the  Orange  County, California  Superior  Court against  Coherent, Westinghouse
Electric Corporation ("Westinghouse") and an individual employee of Westinghouse
who was an officer  of IFS from 1986  to 1993, when the  events involved in  the
federal action against IFS took place and while Westinghouse owned a substantial
minority interest in IFS. The complaint charges that Coherent conspired with IFS
in  the wrongful conduct which  is the subject of  the federal lawsuit described
above and interfered with the Company's
 
                                       40
<PAGE>
contracts and relations with IFS and with prospective contracts and advantageous
economic relations with third parties.  The complaint asserts that  Westinghouse
is  liable for  its employee's  wrongful acts as  an IFS  executive while acting
within the scope of his employment at Westinghouse. The lawsuit seeks injunctive
relief and compensatory damages. In October 1995, the federal action was  stayed
by  order of the court  in favor of the California  state court action, in which
the pleadings have been amended to include all claims asserted by the Company in
the federal action.
 
    In July  1996,  the court  in  the  California state  court  action  granted
demurrers  by Westinghouse  and the  employee of  Westinghouse to  all causes of
action against them,  as well as  all but  one of the  Company's claims  against
Coherent.  As a result, the claims that are the subject of the granted demurrers
have been dismissed, subject to the  Company's right to appeal. The Company  has
decided  that it will file an appeal of  these decisions. No trial date has been
set as to the remaining outstanding causes of action.
 
    In September 1996, the Company instituted litigation in the Salt Lake  City,
Utah  State  Court against  IBC. The  Company's  complaint alleges,  among other
things, conversion, breach of contract and breach of fiduciary duty by IBC as  a
result  of  actions taken  by IBC  with  respect to  the collection  of accounts
receivable due to the  Company. The Court in  this matter subsequently issued  a
temporary  restraining  order  against  IBC, prohibiting  it  from,  among other
things, taking actions to collect receivables generated by the Company's sale of
its products. IBC has filed a cross complaint against the Company, alleging that
the Company breached  the August  24, 1996  agreement between  the parties,  and
seeking  monetary damages. Management of the  Company believes, based in part on
discussions with  counsel,  that IBC's  cross  complaint is  without  merit  and
intends to vigorously defend the action.

DIRECTOR COMPENSATION
 
    All  directors are  elected annually and  hold office until  the next annual
meeting of the  shareholders and  until their  successors are  duly elected  and
qualified.  The  Company  pays to  all  nonemployee directors  $1,000  per Board
meeting attended,  $1,000  per  committee  meeting  attended  which  is  not  in
conjunction  with  a  Board  meeting, $500  per  committee  meeting  attended in
conjunction with a  Board meeting, and  $500 per telephonic  Board or  committee
meeting. Directors are also reimbursed for their out-of-pocket expenses incurred
in  attending meetings of the Board of Directors and its committees. Mr. Shapiro
also receives  a  fee  of  $1,000  per  month  as  compensation  for  additional
consulting  services relating to the Company's  pending litigation matter and to
new business issues. The Company may also periodically award options or warrants
to its Directors. On November 30, 1994, the Company granted to each  nonemployee
director  warrants to  purchase, at  an exercise price  of $5.00  per share, (i)
45,000 shares of Class  A Common Stock,  which warrants vest  on the earlier  of
August 8, 2005 or when the Company attains certain financial conditions (subject
to  earlier vesting upon certain acquisitions of the Company, and subject to the
requirement that the director  remains on the Board  through the vesting  date);
and  (ii)  20,000  shares  of  Class  A  Common  Stock,  which  warrants  vested
immediately upon grant. On  February 23, 1996, the  Company also granted to  Mr.
Day,   the  only  nonemployee  director  of  the  Company  not  on  the  Board's
Compensation Committee, an option to purchase 10,000 shares at an exercise price
of $4.63 per share.
 
    The Company's 1996 Stock Option Plan provides that each person who was or is
a member  of the  Compensation Committee  of  the Board  on February  23,  1996,
February  23, 1997 and February 23, 1998 will be issued on each such date, under
that plan, options  to purchase 10,000  shares of the  Company's Class A  Common
Stock.  These options will have an exercise price equal to the fair market value
of the Company's Class A Common Stock on the trading day prior to the grant date
and a term of  ten years. These  options are issued subject  to approval by  the
Company's  shareholders at  the 1996  Annual Meeting  of Shareholders,  and will
terminate if such approval is not given.
 
    The Company's  Articles  of  Incorporation  and  indemnification  agreements
entered  into between  the Company  and certain  of the  Company's directors and
officers require the  Company to indemnify  such officers and  directors to  the
fullest  extent  permitted by  applicable  law against  liabilities  incurred in
connection with their  duties as  officers and  directors of  the Company.  Such
indemnification  rights  may extend  to  liabilities under  the  Securities Act.
Insofar as indemnification for liabilities arising under the Securities Act  may
be  permitted to directors, officers and controlling persons of the Company, the
Company  has  been  advised  that  in   the  opinion  of  the  Commission   such
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable.

STOCK OPTION PLANS
 
    Each  of the Company's  Stock Option Plans  is administered by  the Board of
Directors  which  has  sole  discretion  and  authority,  consistent  with   the
provisions  of the plans, to determine  which eligible participants will receive
options, the time when options will be granted, the terms of options granted and
the number  of shares  which will  be subject  to options.  The Board  may  also
appoint  a committee (the  "Committee") to administer the  plans and, subject to
applicable law, to exercise all of the powers of the Board under the plans.
 
    1992 STOCK OPTION PLAN AND 1995 STOCK OPTION PLAN
 
   
    The Company's 1992 Stock Option Plan and 1995 Stock Option Plan each provide
for the granting of "incentive stock options," within the meaning of Section 422
of the Internal Revenue  Code of 1986, as  amended ("Incentive Stock  Options"),
and  nonstatutory options. The exercise price of Incentive Stock Options must be
not less than the fair market  value of a share of  Class A Common Stock on  the
date  the option is granted (110% with respect to optionees who own at least 10%
of the outstanding  Common Stock).  Under the  1992 Stock  Option Plan,  options
covering  an aggregate  of 54,264  shares of the  Company's Common  Stock may be
granted and under the  1995 Stock Option Plan  options covering an aggregate  of
225,000  shares of the  Company's Class A  Common Stock may  be granted, in each
case to  directors,  employees  and  consultants of  the  Company,  except  that
Incentive  Stock  Options  may  not  be  granted  to  nonemployee  directors  or
nonemployee consultants. The 1992 Stock  Option Plan terminates in August  2002,
and  the 1995 Stock Option Plan terminates in 2005. As of October 14, 1996 there
were options to purchase an aggregate of  31,896 shares of Class A Common  Stock
and  1,678 shares of  each of Class  E-1 and Class  E-2 Common Stock outstanding
under the 1992 Stock  Option Plan, at  an exercise price  ranging from $1.00  to
$11.06,  which were held by 17 former and current employees, and 177,250 options
outstanding under the 1995 Stock Option Plan at an exercise price of $5.625  per
share, held by 30 employees and consultants.
    
 
    FEBRUARY 1996 STOCK OPTION PLAN AND 1996 STOCK OPTION PLAN
 
   
    In  February  1996, the  Board of  Directors adopted  two option  plans, the
February 1996 Stock Option Plan and the 1996 Stock Option Plan which provide for
the grant of options covering an aggregate of 550,000 shares and 500,000 shares,
respectively, of the Company's Class A  Common Stock to employees and  directors
of,  and consultants to the Company. Both  plans terminate in February 2006. The
1996 Stock Option Plan provides for the granting of Incentive Stock Options  and
nonstatutory stock options. The 1996 Stock Option Plan provides that each person
who  was or is a member of the  Company's Compensation Committee of the Board of
Directors on February 23, 1996, February 23, 1997 and February 23, 1998 will  be
issued  on each such  date, options to  purchase 10,000 shares  of the Company's
Common Stock. These options will have a term of ten years and an exercise  price
equal  to the  fair market value  of the Company's  Class A Common  Stock on the
trading day prior to the grant date. As of October 14, 1996, there were  options
to  purchase an aggregate of 20,000 shares of the Company's Class A Common Stock
outstanding under the 1996 Stock Option Plan, at an exercise price of $4.625 per
share, which options  were held by  two directors of  the Company. The  February
1996 Stock Option Plan provides for the grant of nonstatutory options to certain
key  employees and  consultants to  the Company, but  does not  permit grants to
nonemployee directors of  the Company. The  February 1996 Stock  Option Plan  is
administered  by the  Compensation Committee  of the  Board of  Directors. As of
October 14, 1996, there were options to purchase an aggregate of 494,650  shares
of  Class A Common Stock outstanding under  the February 1996 Stock Option Plan,
at an  exercise  price of  $4.625  per share,  which  options were  held  by  49
employees, directors and consultants.
    
 
    Except  for formula grants  under the 1996  Stock Option Plan,  the Board of
Directors (or a committee  thereof) has the authority  to determine the time  or
times  at which options granted under the Stock Option Plans become exercisable,
provided that options  expire no later  than ten  years from the  date of  grant
(five  years with respect to  optionees who own at  least 10% of the outstanding
Class A Common Stock). Options are  nontransferable, other than by will and  the
laws  of descent  and distribution,  and generally may  be exercised  only by an
employee while employed by  the Company or within  60 days after termination  of
employment (one year for termination resulting from death or disability).

                              CERTAIN TRANSACTIONS
 
    As  of September  30, 1994, the  Company owed an  aggregate of approximately
$226,000 to  its  officers  for unreimbursed  expenses  and  deferred  salaries.
Included  in that amount  was $52,000 owed  to an immediate  family member of an
officer of the Company for consulting  services rendered to the Company. All  of
these  amounts were paid in December 1994 and January 1995. In addition, between
June and  September 1994,  the  Company borrowed  an  aggregate of  $55,000  and
$25,000  from Messrs.  Patrick J.  Day (a  director) and  Irving M.  Frankman (a
former director), respectively, pursuant to short-term promissory notes  bearing
interest  at 10% per annum  (18% upon the occurrence of  an event of a default).
These loans have been repaid in full.
 
    In March 1994, the Company's Board  of Directors agreed to extend Mr.  Day's
outstanding  warrants to purchase 100,000 shares of Series A Preferred Stock for
two years. In December 1994, the  Company exchanged these warrants for  warrants
to  purchase 9,044 shares of  Class A Common Stock, and  8,008 shares of each of
Class E-1  and  Class  E-2 Common  Stock  for  an aggregate  purchase  price  of
$100,000.  In May 1996, the  Company's Board of Directors  agreed to extend such
warrants until March 31, 1997.
 
    In connection  with the  Company's  private placement  in August  1994,  Mr.
Shapiro,  a  director of  the Company,  purchased  $100,000 principal  amount of
promissory notes and 70,000 warrants (which converted by their terms in December
1994 into Class A Warrants) for  an aggregate purchase price of $100,000.  These
promissory notes were repaid in full in December 1994.

                           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 as
exhibits to the Registration Statement of which this Prospectus is a part.
 
UNITS
 
   
    Each Unit consists of 190 shares of  the Company's Class A Common Stock  and
95  of the  Company's Class  B Warrants.  See "--  Common Stock;  Class A Common
Stock," "-- Redeemable Warrants; Class B Warrants," and "Underwriting -- Pricing
the Offering."
    
 
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, subject to certain escrow  conditions
pertaining  to dividends declared  with respect to  the Class E-1  and Class E-2
Common Stock. See "Dividend Policy."
 
    CLASS A COMMON STOCK
 
   
    Shareholders have no preemptive rights and no right to convert their Class A
Common Stock into any other securities. The holders 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 Class A 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 Class A 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 Class A 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 Class A 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 Class A Common Stock within the  limits
authorized  by  the  Company's charter  and  without shareholder  action.  As of
October  14,  1996  there  were  4,750,554  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 October 14,  1996, there were outstanding  1,256,818
shares  of Class E-1 Common Stock and 1,256,818 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 Class
A 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 Class  A 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 shares of Class E-1 Common Stock will be automatically  converted
into  Common  Stock in  the  event that:  (a)  the Company's  net  income before
provision for income taxes, including earnings from joint ventures, distribution
agreements and licensing agreements,  but exclusive of  any other earnings  that
are  classified as an extraordinary item, and exclusive of any charges to income
that may result from  the conversion of  the Escrow Shares  into Class A  Common
Stock  (as stated in the Company's financial statements audited by the Company's
independent  accountants)  ("Minimum  Pretax   Income")  amounts  to  at   least
$5,500,000  for the fiscal  year ending March  31, 1997; (b)  the Minimum Pretax
Income amounts to at least $6,850,000 for the fiscal year ending March 31, 1998;
 
                                       51
<PAGE>
(c) the Minimum Pretax Income amounts to at least $8,425,000 for the fiscal year
ending March  31,  1999; (d)  the  Minimum Pretax  Income  amounts to  at  least
$9,900,000  for the fiscal year ending March  31, 2000; or (e) the Closing Price
of the Company's Class A Common Stock for any 30 consecutive business days shall
average in excess of $19.25 during the period commencing June 1996 and ending in
November 1997 (subject to adjustment in the event of any reverse stock splits or
similar events). The Closing Price shall  be the closing sale price as  reported
by the Nasdaq National Market. In the event additional shares are issued, all of
the Minimum Pretax Income amounts will be increased proportionately.
 
    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: (a) the
Minimum Pretax Income amounts to at least $11,800,000 for the fiscal year ending
March 31, 1997; (b)  the Minimum Pretax Income  amounts to at least  $14,750,000
during  the fiscal  year ending  March 31, 1998;  (c) the  Minimum Pretax Income
amounts to at least  $20,475,000 during the fiscal  year ending March 31,  1999;
(d)  the Minimum Pretax Income amounts to at least $26,750,000 during the fiscal
year ending March 31,  2000; or (e)  the Closing Price  of the Company's  Common
Stock  for any 30  consecutive business days  shall average in  excess of $24.00
during the period commencing  June 1996 and ending  November 1997. In the  event
any  additional  shares are  issued, all  of the  Minimum Pretax  Income amounts
referenced above will be proportionately increased.
 
    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 or  market
price  levels are attained, the Escrow Shares, as well as any dividends or other
distributions made with  respect thereto,  will be cancelled.  The earnings  and
market  price 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 or any increase  in the market price of its  securities.
There  can be no  assurance that such  earnings and market  price levels will be
attained or that any or all of the Escrow Shares will be converted into Class  A
Common  Stock. However,  the conversion to  Class A  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.  See "Management's
Discussion and  Analysis of  Financial Condition  and Results  of Operations  --
Potential Future Charge to Income."
 
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  Class A  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  Class A Common
Stock  by  creating  more  series  of  Preferred  Stock  with  distribution   or
liquidation  preferences senior to the Class A  Common Stock. The Company has no
present plan to issue any shares of Preferred Stock.

<PAGE>
REDEEMABLE WARRANTS
 
    The Company has outstanding redeemable Class A Warrants and Class B Warrants
(collectively, the "Warrants") which are currently listed on the Nasdaq National
Market. These Warrants  were or will  be issued pursuant  to Warrant  Agreements
(the "Warrant Agreements") among the Company, the Underwriter and American Stock
Transfer  and Trust Company  as warrant agent,  and are or  will be evidenced by
warrant certificates in  registered form.  The exercise prices  of the  Warrants
were  determined by negotiation  between the Company and  the Underwriter at the
time of the IPO and should not be  construed to predict or imply that any  price
increases will occur in any of the Company's securities.
 
    The  Warrants may be exercised upon  surrender of the Warrant certificate on
or prior  to the  respective  expiration dates  (or earlier  redemption  dates),
accompanied  by payment of the  full exercise price (by  certified or bank check
payable to the order of  the Company) for the number  of shares with respect  to
which  the Warrants are being exercised. Holders of the Warrants do not have any
voting or other  rights of  a shareholder  of the  Company. Upon  notice to  the
holders  of the Warrants, the  Company has the right  to unilaterally reduce the
exercise price  or extend  the expiration  date of  the Warrants.  The  Warrants
provide  for the adjustment of the exercise price and for a change in the number
of shares issuable upon exercise to protect the holders of the Warrants  against
dilution  in  the  event  of  a  stock  dividend,  stock  split,  combination or
reclassification of the  Class A  Common Stock  or upon  issuance of  additional
shares  of Class A  Common Stock at prices  lower than the  market price then in
effect other  than issuances  upon  exercise of  options granted  to  employees,
directors and consultants to the Company.
 
    CLASS A WARRANTS
 
   
    Each Class A Warrant entitles the registered holder to purchase one share of
Common Stock and one redeemable Class B Warrant at an exercise price of $6.50 at
any  time prior to  November 30, 1999. As  of October 14,  1996, the Company has
outstanding 4,120,149 Class A Warrants. The Company has the right to redeem  all
of  the Class A Warrants at  a price of $0.05 per  Class A Warrant upon not less
than 30 days' prior written notice at any time after November 30, 1997, provided
that before any  such redemption  can take  place, the  last sale  price of  the
Company's  Class  A  Common  Stock in  the  over-the-counter  market  shall have
averaged in excess of  $9.10 per share for  30 consecutive business days  ending
within 15 days of the date of the notice of redemption. During the 30-day notice
period,  a holder shall have  the option to exercise  his Class A Warrants. This
right of redemption shall not apply to the Class A Warrants that are  components
of the IPO Unit Purchase Options.
    
 
    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 October 14, 1996, the Company had outstanding 3,127,049
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  after November  30,  1997, provided  that before  any such
redemption can take place, the last sale  price of the Company's Class A  Common
Stock in the over-the-counter market shall have averaged 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 Unit  Purchase Option  to  be granted  in connection  with  this
Offering.
    
 
IPO UNITS
 
    The Company also has outstanding IPO Units which are currently listed on the
Nasdaq  SmallCap Market.  Each IPO  Unit consists  of (i)  one share  of Class A
Common Stock, (ii) one Class A Warrant and (iii) one Class B Warrant. The  Class
A  Common  Stock,  Class  A  Warrants  and  Class  B  Warrants  were  separately
transferable immediately upon issuance.
 
                                       53
<PAGE>
IPO UNIT PURCHASE OPTIONS
 
   
    In connection with the Company's IPO, the Company granted to the Underwriter
and three finders IPO Unit  Purchase Options to purchase  up to an aggregate  of
240,000  units.  These units  issuable upon  exercise of  the IPO  Unit Purchase
Options will be identical to the publicly traded IPO Units except that the Class
A Warrants and the Class  B Warrants included in  the IPO Unit Purchase  Options
will  not be  subject to redemption  by the Company,  except if at  the time the
Warrants are called  for redemption,  the IPO  Unit Purchase  Options have  been
exercised  and the  underlying warrants are  outstanding. The  IPO Unit Purchase
Options are exercisable at any  time prior to November  30, 1999 at an  exercise
price  of $7.00 per IPO Unit subject  to adjustment in certain events to protect
against dilution. The  IPO Unit  Purchase Options cannot  be transferred,  sold,
assigned  or  hypothecated until  November 30,  1997,  except in  the case  of a
transfer to any  officer of  the underwriter  for the IPO  or a  member of  that
selling group.
    
 
LIMITATION OF LIABILITY OF DIRECTORS AND 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 provides 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  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  to  the  Company   or  its  shareholders,  for  improper
transactions 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  concerning 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  Commission such indemnification  is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.
 
TRANSFER AND WARRANT AGENT
 
    The Company's transfer agent  for the IPO Units,  Class A Common Stock,  the
Class  A Warrants and  the Class B  Warrants is American  Stock Transfer & Trust
Company, New York, New York.

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon  completion  of  the  Offering,  the  Company  will  have   outstanding
(excluding outstanding options and warrants) an aggregate of 6,840,554 shares of
Class  A Common Stock. Of these shares, all of the shares issued in the Offering
and 3,708,997  shares outstanding  immediately  prior to  the Offering  will  be
freely  transferable  without restriction  under  the Securities  Act. 1,041,557
shares of Class A Common Stock outstanding immediately prior to the Offering are
"restricted securities" (the "Restricted Shares") within the meaning of Rule 144
promulgated under the Securities  Act and may  not be sold in  the absence of  a
registration  under the Securities Act unless  an exemption from registration is
available, including an exemption contained in Rule 144.
    
 
   
    In general, under Rule  144 as currently in  effect, any person (or  persons
whose shares are aggregated for purposes of Rule 144) who has beneficially owned
"restricted  securities," as that term is defined  in Rule 144, for at least two
years (including, in the case of a nonaffiliate holder, any period of  ownership
of  preceding nonaffiliate holders) is entitled  to sell, within any three-month
period, a number of  shares that does not  exceed the greater of  (i) 1% of  the
then  outstanding shares  of Class A  Common Stock  of the Company,  or (ii) the
average weekly trading volume in Class  A Common Stock during the four  calendar
weeks  preceding such sale,  provided that certain  public information about the
Company, as required by Rule 144, is then available and the seller complies with
the manner of sale and  notification requirements of the  rule. A person who  is
not  an affiliate and has not been an affiliate within three months prior to the
sale and  has,  together with  any  previous  owners who  were  not  affiliates,
beneficially owned restricted securities for at least three years is entitled to
sell  such  shares  under  Rule  144(k) without  regard  to  any  of  the volume
limitations described above. Approximately 861,932 of the Restricted Shares  are
presently eligible for sale upon compliance with Rule 144(k).
    
 
   
    As  of October  14, 1996,  11,367,347 shares  of Class  A Common  Stock were
issuable upon exercise in full of the outstanding Warrants and their  underlying
securities,  all of which have been registered under the Securities Act and will
be freely tradeable  upon issuance. An  additional 2,380,336 shares  of Class  A
Common  Stock are  issuable upon  exercise of  other stock  options and warrants
outstanding as of October 14, 1996. Of these shares, 1,147,006 shares have  been
registered  under the Act  (or carry registration rights)  and 718,680 shares of
Class A Common  Stock are issuable  upon exercise of  the remaining options  and
warrants  and may be resold pursuant to  Rule 701 under the Securities Act. Rule
701 under  the  Securities  Act  provides an  exemption  from  the  registration
requirements  of the  Securities Act for  offers and sales  of securities issued
pursuant to certain compensatory benefit plans or written contracts of a company
not subject, at the time of  issuance, to the reporting requirements of  Section
13  or 15(d)  of the Exchange  Act. Securities  issued pursuant to  Rule 701 are
defined as restricted  securities for  purposes of  Rule 144.  However, 90  days
after  the issuer  becomes subject to  the reporting provisions  of the Exchange
Act, the  Rule 144  resale  restrictions, except  for the  broker's  transaction
requirements,  are inapplicable for nonaffiliates. Affiliates are subject to all
Rule 144 restrictions after this 90-day period, but without the Rule 144 holding
period requirement.  The officers  and directors  of the  Company (who  hold  an
aggregate  of 161,352 shares of Class A Common Stock) have agreed not to sell or
otherwise transfer  any  shares of  Class  A  Common Stock,  or  any  securities
convertible into or exercisable for shares of Class A Common Stock, for at least
13  months following the  effective date of the  Registration Statement of which
this Prospectus forms a part without the consent of the Underwriter.
    
 
    The Company is unable to  predict the effect, if  any, that future sales  of
shares  of Class A Common  Stock, or the availability  of shares for future sale
will have on the market price of  the Class A Common Stock prevailing from  time
to  time. Sales  of substantial amounts  of Class  A Common Stock  in the public
market, or the perception  that such sales could  occur, could adversely  affect
the  prevailing  market  prices of  the  Class  A Common  Stock.  See "Principal
Shareholders," "Description of Securities" and "Underwriting."

                                  UNDERWRITING
 
    D.H. Blair Investment Banking Corp., the Underwriter, has agreed, subject to
the terms and conditions of the  Underwriting Agreement, to purchase the  11,000
Units  offered hereby from the Company on  a "firm commitment" basis, if any are
purchased. It is expected that Blair &  Co. will distribute, as a selling  group
member,  substantially all of the Units offered hereby. It is also expected that
Blair & Co. will continue to make a market in the Company's securities following
the Offering. Blair & Co. is substantially owned by family members of J.  Morton
Davis. Mr. Davis is the sole stockholder of the Underwriter.
 
    The  Underwriter has advised the Company that it proposes to offer the Units
to the public at the public offering price  set forth on the cover page of  this
Prospectus  and to certain  dealers who are  members of the  NASD at such prices
less concessions of not in  excess of $       per Unit,  of which not more  than
$       per Unit may be  reallowed to other dealers who are members of the NASD.
After commencement of the  Offering, the public  offering price, the  concession
and reallowance may be changed by the Underwriter.
 
    The  Company has  granted to the  Underwriter an option,  exercisable for 45
days from the  date of  this Prospectus,  to purchase  from the  Company at  the
public offering price, less underwriting discounts, up to 1,650 additional Units
solely for the purpose of covering over-allotments, if any.
 
    The  Company  has  agreed  to  indemnify  the  Underwriter  against  certain
liabilities, including liabilities  under the  Securities Act.  The Company  has
also  agreed to pay the Underwriter a  nonaccountable expense allowance of 3% of
the gross proceeds derived from the sale of the Units offered hereby,  including
any Units purchased pursuant to the Over-Allotment Option.
 
    All  of the  Company's current  officers and  directors, as  well as certain
shareholders of  the Company,  have  agreed not  to  sell, assign,  transfer  or
otherwise  dispose of  any of  their shares  of the  Company's securities  for a
period of 13 months following the consummation of the Offering without the prior
written consent of the Underwriter. See "Shares Eligible for Future Sale."
 
   
    The Company has  agreed, if requested  by the Underwriter,  to nominate  two
designees of the Underwriter to the Company's Board of Directors for a period of
five  years from the date of this  Prospectus. Such designees may be a director,
officer, partner, employee or affiliate of the Underwriter. The Underwriter  has
designated  Mr. Donald Shapiro,  a current director of  the Company, pursuant to
this provision, but has not determined whether it will continue to exercise this
right in the future or whether it  will nominate a second designee. Mr.  Shapiro
is not affiliated with the Underwriter.
    
 
    Until  the fifth anniversary  of the closing  of the Offering,  in the event
that the  Underwriter  originates  a  financing  or  a  merger,  acquisition  or
transaction to which the Company is a party, the Underwriter will be entitled to
receive a finder's fee in consideration for the origination of such transaction.
The  fee is based on a percentage  of the consideration paid in the transaction,
ranging from 7% of the first $1,000,000  to 2.5% of any consideration in  excess
of $9,000,000.
 
   
    The  Company has agreed not to  solicit Warrant exercises other than through
the  Underwriter,  unless  the  Underwriter  refuses  or  fails  to  make   such
solicitation.  Upon  any  exercise  of  the Class  B  Warrants  after  the first
anniversary of the date of this Prospectus, the Company will pay the Underwriter
a fee of  5% of the  aggregate exercise price  (the "Warrant Fee"),  if (i)  the
market  price of the Company's Class A Common Stock on the date the Warrants are
exercised is greater  than the  then exercise price  of the  Warrants; (ii)  the
exercise  of  the Warrants  was solicited  by a  member of  the NASD;  (iii) the
warrant holder  designates in  writing  that the  exercise  of the  Warrant  was
solicited  by  a  member of  the  NASD; (iv)  the  Warrants  are not  held  in a
discretionary account; (v) disclosure of compensation arrangements was made both
at the time of  the offering and at  the time of exercise  of the Warrants;  and
(vi)  the solicitation of exercise  of the Warrant was  not in violation of Rule
10b-6 promulgated under the Exchange Act; provided, however, that to the  extent
Warrants  are  exercised prior  to the  first  anniversary of  the date  of this
Prospectus, the Underwriter shall only be entitled to
    
 
                                       56

receive the Warrant Fee with respect to  the Warrants issued at the time of  the
IPO.  For purposes of determining which Warrants have been exercised, it will be
assumed that the first 6,605,000 Class  B Warrants (which include the  3,845,000
Class  B Warrants  originally issuable  upon exercise  of the  Class A Warrants)
exercised were those issued at the time of the IPO.
    
 
    Rule 10b-6  may prohibit  Blair &  Co. from  engaging in  any market  making
activities  with regard  to the  Company's securities  for the  period from nine
business days (or such other applicable period as Rule 10b-6 may provide)  prior
to  any solicitation by  the Underwriter of  the exercise of  Warrants until the
later of the termination  of such solicitation activity  or the termination  (by
waiver or otherwise) of any right that the Underwriter may have to receive a fee
for  the exercise of Warrants following such  solicitation. As a result, Blair &
Co. may  be unable  to provide  a  market for  the Company's  securities  during
certain periods while the Warrants are exercisable.
 
   
    The  Company has agreed  to sell to  the Underwriter and  its designees, for
nominal consideration, the Unit  Purchase Option to purchase  up to 1,100  Units
(the  "Option Units") substantially identical to the Units being offered hereby,
except that  the Warrants  included therein  are subject  to redemption  by  the
Company  at any time after  the Unit Purchase Option  has been exercised and the
underlying  warrants  are  outstanding.  See  "Description  of  Securities--Unit
Purchase Options." The Unit Purchase Option is exercisable during the three year
period  commencing two  years from  the date of  this Prospectus  at an exercise
price of $1,200 per Unit (120% of the initial public offering price) subject  to
adjustment  in certain events to protect  against dilution. After the expiration
date of the  Warrants, the Unit  Purchase Option will  be exercisable only  with
respect  to the  Class A Common  Stock component  of the Option  Units. The Unit
Purchase Option is not transferable for a  period of two years from the date  of
this  Prospectus, except  to officers  of the Underwriter  or to  members of the
selling group.  Subject  to  certain  procedural  requirements  and  limitations
relating  to  underwritten offerings,  the Company  has  agreed upon  request to
register under  the Securities  Act  securities issuable  upon exercise  of  the
Underwriter's  Unit Purchase  Option on two  separate occasions  during the four
year period commencing one  year from the date  of this Prospectus. The  initial
such  registration is to be at the Company's expense and the second registration
is to be  at the expense  of the holders.  The Unit Purchase  Option includes  a
provision  permitting the holders to elect  a cashless exercise. The Company has
also granted  certain "piggyback"  registration rights  to holders  of the  Unit
Purchase Option.
    
 
   
    The  Company  has agreed  to  pay $35,000  to  a former  underwriter  of the
Offering  as  reimbursement  for  expenses  incurred  by  such  underwriter   in
connection with the Offering.
    
 
    The  public  offering price  of the  Units offered  hereby and  the exercise
prices and  other terms  of the  Warrants have  been determined  by  negotiation
between  the Company and the Underwriter and  are not necessarily related to the
Company's asset value, net worth,  financial condition or any other  established
criteria  of value. Among the factors  considered in determining such prices and
terms, in addition to prevailing market  conditions, are the history of and  the
prospects  for the industry in which the  Company competes, the present state of
the Company's  development  and  its  future prospects,  an  assessment  of  the
Company's management and the Company's capital structure.
 
    The  Underwriter has  informed the Company  that sales of  the Units offered
hereby to discretionary accounts will not exceed 2% of the total number of Units
offered.
 
   
    The Underwriter acted as placement agent for the Company's private placement
in August  1994 and  received a  10% commission  and 3%  nonaccountable  expense
allowance aggregating $201,500. The Underwriter also acted as the underwriter of
the  Company's  initial public  offering  in December  1994  and received  an 8%
commission and 3%  nonaccountable expense  allowance, as  well as  the IPO  Unit
Purchase Options, in connection with such offering. See "Management's Discussion
and  Analysis of  Financial Condition  and Results  of Operations--Liquidity and
Capital Resources."
    
 
    The Commission is  conducting an investigation  concerning various  business
activities of the Underwriter and Blair & Co., a selling group member which will
distribute  substantially  all of  the Units  offered hereby.  The investigation
appears   to   be    broad   in   scope,    involving   numerous   aspects    of
 
                                       57
<PAGE>
the  Underwriter's and Blair & Co.'s compliance with the federal securities laws
and compliance with the federal securities laws by issuers whose securities were
underwritten by the Underwriter or Blair &  Co., or in which the Underwriter  or
Blair   &  Co.  made  over-the-counter  markets,  persons  associated  with  the
Underwriter or Blair & Co., such issuers and other persons. The Company has been
advised by the  Underwriter that  the investigation  has been  ongoing since  at
least  1989 and that  it is cooperating with  the investigation. The Underwriter
cannot predict whether this investigation will ever result in any type of formal
enforcement action against the  Underwriter or Blair &  Co., or, if so,  whether
any  such  action  might  have  an adverse  effect  on  the  Underwriter  or the
securities offered hereby. The  Company has been advised  that Blair & Co.  will
make  a  market  in  the  securities  following  this  offering.  An unfavorable
resolution of the Commission's investigation  could have the effect of  limiting
such  firm's ability to make  a market in the  Company's securities, which could
affect the liquidity or price of such securities.
 
PRICING THE OFFERING
 
   
    The number of shares of Class A  Common Stock and Class B Warrants  included
in  each Unit has been determined by the Underwriter based on the current market
price of  the  Class A  Common  Stock,  but also  reflecting  the  Underwriter's
determination of the number of the shares per Unit needed to successfully market
the  Units  in light  of the  size of  the Offering  relative to  the previously
outstanding number of shares of Class A Common Stock.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
 and Shareholders of
Premier Laser Systems, Inc.
 
In  our opinion,  the accompanying balance  sheet and the  related statements of
operations, shareholders' equity and cash flows present fairly, in all  material
respects,  the financial  position of Premier  Laser Systems, Inc.  at March 31,
1996, and the results of its operations and  its cash flows for each of the  two
years  in the period ended March 31, 1996, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of  the
Company's  management;  our responsibility  is to  express  an opinion  on these
financial statements  based on  our audits.  We conducted  our audits  of  these
statements  in  accordance  with  generally  accepted  auditing  standards which
require that we plan and perform the audit to obtain reasonable assurance  about
whether  the financial  statements are free  of material  misstatement. An audit
includes examining,  on  a  test  basis, evidence  supporting  the  amounts  and
disclosures  in the  financial statements,  assessing the  accounting principles
used and significant estimates  made by management,  and evaluating the  overall
financial   statement  presentation.  We  believe  that  our  audits  provide  a
reasonable basis for the opinion expressed above.
 
    The accompanying financial statements have  been prepared assuming that  the
Company  will  continue  as a  going  concern. As  discussed  in Note  4  to the
financial statements, the Company has suffered recurring losses from  operations
which raises substantial doubt about its ability to continue as a going concern.
Management's  plans in regard to these matters are also described in Note 4. The
financial statements do not include any  adjustments that might result from  the
outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
                    (INFORMATION AS OF JUNE 30, 1996 AND FOR
          THE THREE MONTHS ENDED JUNE 30, 1995 AND 1996 IS UNAUDITED)
 
1.  ORGANIZATION AND NATURE OF OPERATIONS
    Premier  Laser Systems, Inc. (the Company) was incorporated in July 1991 and
commenced operations in  August 1991  after acquiring substantially  all of  the
assets  and certain liabilities of Pfizer  Laser Systems (Pfizer), a division of
Pfizer Hospital Products Group, Inc. The Company designs, develops, manufactures
and markets several  lines of lasers  for surgical and  other medical  purposes,
laser  waveguides and fiber optic  devices, disposables and associated accessory
products for the medical market.
 
    The financial statements as of March 31, 1996 and for each of the two  years
in the period ended March 31, 1996 give effect to the Company's recapitalization
and reverse stock splits discussed in Note 16.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    REVENUE RECOGNITION
 
    The  Company recognizes revenue  upon shipment of  product to customers, and
when no significant contractual obligations remain outstanding.
 
    CASH EQUIVALENTS
 
    Cash equivalents represent short-term,  highly liquid investments that  have
original maturities of three months or less and are readily convertible to cash.
Such  investments consist primarily of U.S. Treasury Notes and commercial paper.
Cost of such investments is equal to the related fair value at March 31, 1996.
 
    SHORT-TERM INVESTMENTS
 
    In fiscal  1995,  the Company  adopted  SFAS 115,  "Accounting  for  Certain
Investments  in  Debt  and Equity  Securities."  Under SFAS  115,  the Company's
investments are classified as  "available-for-sale" securities and are  reported
at  fair market value. Any unrealized holding  gains or losses are reported as a
separate component  of  stockholders'  equity. Realized  gains  and  losses  are
reported on the specific identification method and are reported in the statement
of  operations. The Company's marketable securities  portfolio at March 31, 1996
consists of its investments in the common stock of Mattan Corporation (see  Note
6).
 
    INVENTORIES
 
    Inventories  are stated at the lower of cost or market and include material,
labor, and related manufacturing overhead. The Company determines cost using the
first-in, first-out (FIFO) method.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Expenditures for replacements and
improvements are  capitalized  and  expenditures for  repairs,  maintenance  and
routing  replacements are charged to operating  expense as incurred. When assets
are sold or otherwise disposed of, the cost and related accumulated depreciation
are eliminated from the accounts and any  resulting gain or loss is included  in
operations.
 
    Depreciation  of  furniture,  machinery  and equipment  is  calculated  on a
straight-line basis over the estimated useful  lives of the assets ranging  from
three to eight years.
 
    INTANGIBLES
 
    Intangible  assets  consists  primarily of  patents,  technology  rights and
license agreements. The costs assigned  to acquired intangible assets, based  in
part upon independent appraisals, are being

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                    (INFORMATION AS OF JUNE 30, 1996 AND FOR
          THE THREE MONTHS ENDED JUNE 30, 1995 AND 1996 IS UNAUDITED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
amortized on a straight-line basis over the estimated useful lives of the assets
ranging   from  2  to   15  years.  Periodically,   the  Company  evaluates  the
recoverability of intangibles based on estimated undiscounted future cash  flows
from operating activities compared with the carrying values of the intangibles.
 
    DEFERRED OFFERING COSTS
 
    Costs  incurred directly related to  the Company's proposed secondary public
offering totalling $444,910 at June 30, 1996 have been capitalized and  included
in  other current  assets. Upon  successful completion  of this  offering, these
costs will be offset against the proceeds received and charged to  shareholders'
equity.
 
    RESEARCH AND DEVELOPMENT COSTS
 
    Research  and  development costs  are  expensed as  incurred.  A substantial
portion of the  research and development  expense is related  to developing  new
products,  improving  existing  products  or  processes,  and  clinical research
programs.
 
    The Company  enters  into agreements  with  certain doctors  to  exchange  a
portion  of  a  product's sales  price  for  completion of  certain  portions of
clinical studies necessary for obtaining product  approval by the U.S. Food  and
Drug  Administration. Typically, the amounts consist of a portion of the product
sales price which is equal to the fair  value of the services to be rendered  by
the  doctor. Pursuant to  the agreements, in  the event the  doctor is unable to
complete the agreed upon  clinical study, the doctor  is required to remit  cash
payment  for the entire amount. The  amounts are capitalized as prepaid research
and development expense and amortized  upon completion of certain milestones  of
the  clinical  study. These  studies are  generally  completed within  one year.
Research and development expenses included in prepaid expenses totaled  $204,000
at March 31, 1996.
 
    INCOME TAXES
 
    The  Company  accounts  for income  taxes  in accordance  with  Statement of
Financial Accounting Standards No. 109 (SFAS 109), ACCOUNTING FOR INCOME  TAXES.
SFAS  109 requires  the liability method  for accounting for  income taxes. This
method mandates  the recognition  of  deferred tax  liabilities and  assets  for
expected  future tax consequences of  temporary differences between the carrying
amounts and tax bases of assets and liabilities.
 
    NET LOSS PER SHARE
 
    Net loss per share was computed based on the weighted average number of  the
Company's  common shares outstanding during fiscal  1996 and excludes all shares
of Class E-1 and Class E-2 Common  Stock, discussed in Note 16, outstanding,  or
subject  to option, because all  such shares of stock  are subject to escrow and
the conditions for the  release of shares from  escrow have not been  satisfied.
Common  stock  equivalents  were  not  considered  in  the  net  loss  per share
calculation because the effect on the net loss would be antidilutive.
 
    PRO FORMA NET LOSS PER SHARE (UNAUDITED)
 
    Net loss per common share was computed based on the weighted average  number
of  the Company's common  shares outstanding during the  fiscal year ended March
31, 1995 after giving retroactive adjustment for the recapitalization  discussed
in Note 16 and the conversion of the Company's debentures into units (as defined
in  Note  5) which  occurred  upon completion  of  the Company's  initial public
offering (see Note 5). The effect on net loss per common share of the conversion
of the Company's debentures was to reduce historical net loss by $67,995 and  to
increase weighted average

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
shares  outstanding by 321,099 shares for the  fiscal year ended March 31, 1995.
Class E-1 and E-2 common stock shares, discussed in Note 16, were excluded  from
the  net loss per share calculation because the conditions for release of shares
from escrow have  not been satisfied.  Other common stock  equivalents were  not
considered  in the net loss per share  calculation because the effect on the net
loss per  share  would be  antidilutive.  Pursuant to  Securities  and  Exchange
Commission  Staff Accounting  Bulletin No.  83, all  stock options  and warrants
granted and common shares issued within one year of the Company's initial public
offering and not in escrow have been included as outstanding for the six  months
ended  September  30, 1994  (the date  of the  most recent  financial statements
included in the Company's initial public offering prospectus) using the treasury
stock method.
 
    ACCOUNTING FOR STOCK-BASED COMPENSATION
 
    The Financial Accounting Standards Board  has issued Statement of  Financial
Accounting  Standards No. 123, "Accounting  for Stock-Based Compensation" ("SFAS
123"), effective for years beginning after December 15, 1995, which  establishes
a  fair value-based method of accounting for stock-based compensation plans. The
statement  allows  companies  to  continue  to  use  the  intrinsic  value-based
approach,  supplemented by footnote  disclosure of the pro  forma net income and
earnings per share  of the  fair value-based  approach. The  Company intends  to
follow this method allowed by SFAS 123.
 
    USE OF ESTIMATES BY MANAGEMENT
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted accounting principles requires management to make certain estimates and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
    Significant   estimates  and  assumptions  include  those  made  surrounding
inventory valuation  and the  realizability of  certain intangible  assets.  The
Company's  inventory and intangibles  largely relate to  technologies which have
yet to gain wide spread market  acceptance. Management believes no loss will  be
incurred  on the  disposition of its  inventory and that  the remaining economic
life of  the Company's  tangible assets  is reasonable.  If wide  spread  market
acceptance  of the  Company's products is  not achieved, the  carrying amount of
inventory and intangible assets could be materially reduced.
 
    INTERIM RESULTS (UNAUDITED)
 
    The accompanying  balance sheet  at June  30, 1996,  and the  statements  of
operations  and cash flows for  the three month periods  ended June 30, 1995 and
1996, and the statement of shareholders' equity for the three month period ended
June 30, 1996 are unaudited. In the opinion of management, these statements have
been prepared on the same basis as the audited financial statements and  include
all  adjustments, consisting of only normal recurring adjustments, necessary for
the fair statement  of results  of the interim  periods. The  data disclosed  in
these notes to the financial statements for those periods are also unaudited.

    SUPPLEMENTAL DISCLOSURE OF NONCASH INVESTING AND FINANCING ACTIVITIES
 
    In fiscal 1996, the Company issued 200,000 shares of Class A Common Stock in
connection  with  the acquisition  of 1,150,000  shares of  Mattan Corporation's
common stock.  The value  of  the Mattan  Corporation  common stock  shares  was
$881,010 on the date of the transaction (see Note 6).
 
    Concurrent  with the  completion of  the Company's  initial public offering,
certain  notes  payable  to   shareholders  totaling  $66,500  and   convertible
debentures  totaling $1,500,000,  plus related accrued  interest, were converted
into 7,072 shares of Class A Common Stock and 6,260 shares of each Class E-1 and
E-2 Common Stock, and 321,099 Units, respectively.
 
4.  BASIS OF PRESENTATION
    The Company has suffered recurring  losses from operations and may  continue
to  incur  losses  for  the  foreseeable future  due  to  the  significant costs
anticipated to  be  incurred in  connection  with manufacturing,  marketing  and
distributing  its laser  products. In addition,  the Company  intends to conduct
continuing research and development activities, including regulatory  submittals
and clinical trials to develop additional applications for its laser technology.
The  Company operates in a highly competitive  environment and is subject to all
of the risks  inherent in a  new business enterprise.  The Company is  presently
attempting to borrow funds and/or complete a public offering of its common stock
to  provide working capital for operations in the near term. The outcome of such
efforts to raise working  capital cannot be assured.  The ultimate timeframe  in
which  a sufficient  level of  product or market  acceptance can  be achieved is
uncertain. As such, there  is substantial doubt about  the Company's ability  to
continue as a going concern.
 
    The  Company's  financial  statements have  been  prepared on  the  basis of
accounting principles applicable to  a going concern.  Accordingly, they do  not
purport  to give effect to adjustments, if any, that may be necessary should the
Company be  required  to  realize  its assets  and  liquidate  its  liabilities,
contingent  liabilities  and  commitments in  other  than the  normal  course of
business at amounts different from those disclosed in the financial statements.
 
5.  INITIAL PUBLIC OFFERING
    On December  7,  1994, the  Company  completed an  initial  public  offering
consisting  of 2,400,000 Units of the Company's securities, each unit consisting
of one share of  Class A Common  Stock, one redeemable Class  A Warrant and  one
redeemable  Class B Warrant (the "Units").  The Company realized net proceeds of
$9,542,000 from this  offering. Each Class  A Warrant consists  of the right  to
purchase  one share of Class A Common Stock  and one Class B Warrant at any time
through the fifth anniversary date of the initial public offering at an exercise
price of $6.50. Each Class B Warrant consists of the right to purchase one share
of Class A Common Stock from the date of issuance through the fifth  anniversary
date  of the initial  public offering's effective  date at an  exercise price of
$8.00.

5.  INITIAL PUBLIC OFFERING (CONTINUED)
    On January  12,  1995,  the  underwriter  in  the  initial  public  offering
exercised  its over-allotment  option to purchase  360,000 Units  at the initial
public offering price, resulting in net proceeds of $1,411,183 to the Company.
 
6.  STRATEGIC ALLIANCES
    In December 1995, the  Company entered into  a strategic marketing  alliance
with Mattan Corporation (Mattan), a Canadian corporation whose stock is publicly
traded  on the Alberta Stock Exchange.  The purchasing agreement (the Agreement)
stipulates that  the Company  will  supply all  laser equipment  and  associated
disposables for all laser surgery centers to be designed and opened by Mattan in
Canada  and the United States. It is anticipated that these surgery centers will
be operated under the name of Medical Laser Institute of America. In  connection
with  this alliance,  the Company also  entered into a  share exchange agreement
pursuant to which  the Company issued  200,000 shares of  the Company's Class  A
Common Stock, to certain parties affiliated with Mattan, who purchased 1,150,000
shares  of  Mattan's common  stock, representing  approximately 12%  of Mattan's
common stock, for approximately $881,010 on the Company's behalf. Prior to March
31, 1996, the Mattan affiliates sold the 200,000 shares of the Company's Class A
Common Stock and released the shares of the Mattan common stock to the  Company.
The  Company  accounts for  this  investment as  an  available-for-sale security
pursuant to SFAS 115  (See Note 2). At  March 31, 1996, the  fair value of  this
investment  totaled approximately $4,547,377 and  the related unrealized holding
gain totaled approximately $3,666,367.
 
    In October 1995, the Company entered into a strategic business alliance with
International Biolaser  Corporation (IBC).  This  agreement specifies  that  the
Company  will manufacture  IBC's CO(2) and  argon lasers and  that such products
will be jointly marketed  by the two companies.  Pursuant to the agreement,  the
Company  advanced $125,000 to IBC in exchange for a convertible note payable due
in October 1997, bearing interest at 10% per annum and secured by  substantially
all  of  IBC's  intangible assets.  This  note  payable is  convertible,  at the
Company's sole option, into an 80% ownership interest in IBC only after IBC  has
repaid  certain pre-existing  indebtedness. See  Note 19  for further discussion
regarding amendments to the Company's agreement with IBC.

11. RELATED PARTY TRANSACTIONS
    As discussed in  Note 1,  the Company commenced  operations after  acquiring
substantially  all of  the assets  and certain  liabilities of  Pfizer in August
1991. At March 31, 1996, notes payable to Pfizer totaled $481,195 (see Note 12).
 
    Consulting fees aggregating $12,000 and  $26,000 for the fiscal years  ended
March 31, 1996 and 1995, respectively, were paid to a consultant of the Company,
directly related to an officer of the Company.
 
12. NOTES PAYABLE TO RELATED PARTY AND EXTRAORDINARY GAIN
    Prior  to the completion of the initial public offering described in Note 5,
the Company's notes  payable to Pfizer  amounted to $2,517,390.  Pursuant to  an
agreement  between the  Company and Pfizer,  the Company paid  $1,386,195 of the
notes payable to  Pfizer immediately subsequent  to the closing  of the  initial
public  offering  and Pfizer  forgave $650,000  of  the total  indebtedness. The
remaining balance of $481,195,  bearing interest at 10%  per annum at March  31,
1996,  and  related  accrued  interest  are  payable  in  quarterly installments
commencing July 8, 1996 with the first principal payment totaling $240,598, plus
accrued interest, and  the remaining two  quarterly principal payments  totaling
$120,299,  plus accrued interest.  If the Company completes  a private or public

equity offering  which raises  net proceeds  of at  least $3  million, the  note
payable balance outstanding at the time of that offering becomes immediately due
and  payable. The note payable  to Pfizer is secured  by certain of the tangible
and intangible assets  of the  Company. See further  discussion concerning  this
note payable under Note 19.
 
    In  June 1994, notes  payable to third parties  of $1,500,000 were converted
into convertible debentures. These debentures and related accrued interest  were
converted  into 321,099 Units concurrent with  the closing of the initial public
offering. Also  concurrent with  the close  of the  offering, notes  payable  to
shareholders  totaling $66,500 plus related accrued interest were converted into
7,072 shares of Class A Common Stock and 6,260 shares of each Class E-1 and  E-2
Common Stock.
 
    In  August 1994,  the Company completed  a private placement  of debt units,
whereby $1,550,000  of notes  payable bearing  interest at  10% per  annum  (the
"Bridge  Notes") and  warrants to  purchase 1,085,000  shares of  Class A common
stock were  issued.  In connection  with  this private  placement,  the  Company
incurred placement costs of $201,500 and issued the notes at a discount totaling
$186,000. These notes payable were also paid in full in December 1994.
 
    In connection with the debt forgiven by Pfizer and the extinguishment of the
bridge  notes, the Company recognized a net extraordinary gain on extinguishment
of debt totaling $381,730.
 
13. GRANTS
    In September,  1995,  the  Company  obtained  a  Small  Business  Innovative
Research   Grant  totaling  approximately  $750,000   for  the  study  of  laser
emulsification. Pursuant to the terms of  the grant, the Company is eligible  to
receive  reimbursement for research and development costs incurred in connection
with the  laser emulsification  study up  to $750,000  upon the  achievement  of
certain  deliverables,  as defined.  During  fiscal 1996,  the  Company received
approximately $250,000 under  the grant.  The amounts received  under the  grant
were offset against research and development costs incurred in the study.
 
14. COMMITMENTS AND CONTINGENCIES

14. COMMITMENTS AND CONTINGENCIES (CONTINUED)
    The Company entered  into employment  agreements with three  members of  its
executive  management team. These  agreements provide for two  to four months of
severance benefits upon termination of  employment. Based upon salary levels  as
of  March 31, 1996, such severance  benefits range from approximately $15,000 to
$33,000 for each of the above members of management.
 
    CONTINGENCIES
 
    The Company  entered into  an agreement  with Infrared  Fiber Systems,  Inc.
(IFS),  as a  supplier of  certain fiberoptics that  expires in  the fiscal year
ending March  31, 2002  and requires  the supplier  to sell  exclusively to  the
Company  fiberoptics for medical and dental  applications as long as the Company
purchases defined minimum amounts.
 
    In March 1994, the Company  initiated litigation against IFS. The  Company's
complaint  alleges that IFS and two  of its officers misrepresented IFS' ability
to supply optical fibers, and that IFS breached its supply agreement and certain
warranties. In  April  1994, IFS  filed  a cross-complaint  alleging  breach  of
contract  and  intentional  interference  with  prospective  economic advantage,
seeking declaratory relief that the contract has been terminated and that IFS is
free to market  its fibers  to others.  In July  1994, Coherent,  Inc., a  major
shareholder of IFS and a manufacturer of medical lasers which employ IFS optical
fibers,  joined the lawsuit for the express purpose of defending their rights to
the  IFS  optical  fibers.  In  May  1995,  the  Company  instituted  litigation
concerning  this dispute in the Orange County, California Superior Court against
Coherent, Westinghouse Electric Corporation  ("Westinghouse") and an  individual
employee  of Westinghouse who was an officer of  IFS from 1986 to 1993, when the
events involved  in  the  federal  action  against  IFS  took  place  and  while
Westinghouse owned a substantial minority interest in IFS. The complaint charges
that Coherent conspired with IFS in the wrongful conduct which is the subject of
the  federal lawsuit and  interfered with the  Company's contracts and relations
with IFS and with prospective contracts and advantageous economic relations with
third parties.  The  complaint  asserts  that Westinghouse  is  liable  for  its
employee's  wrongful acts as an  IFS executive while acting  within the scope of
his  employment  at  Westinghouse.  The  lawsuit  seeks  injunctive  relief  and
compensatory  damages. In October 1995 the federal action was stayed by order of
the court in favor of the California state court action, in which the  pleadings
have  been amended to include all claims  asserted by the Company in the federal
action. No  trial  date has  been  set. The  Company  believes that  the  likely
liability  of the Company, if any, arising from this litigation would not have a
materially adverse impact upon the Company.
 
    The Company is involved in various disputes and other lawsuits from time  to
time  arising from its  normal operations. The  litigation process is inherently
uncertain and it is possible that the resolution of the IFS litigation, disputes
and other  lawsuits may  adversely affect  the  Company. It  is the  opinion  of
management,  that the outcome of  such matters will not  have a material adverse
impact on  the Company's  financial  position, results  of operations,  or  cash
flows.
 
15. INCOME TAXES
    The  Company incurred losses  totaling $5,752,895 and  $3,808,485 for fiscal
years ended March 31, 1996 and 1995, respectively. As a result, no provision for
income taxes has been charged to continuing operations during these periods.

</TABLE>
 
    The net change  in the valuation  allowance for deferred  tax assets was  an
increase  of approximately  $2,634,142 from the  balance at March  31, 1995. The
change  primarily  relates  to  additional  net  operating  loss   carryforwards
generated as well as changes in other deferred assets in fiscal 1996, which were
fully reserved for at March 31, 1996.
 
    At  March 31,  1996, the  Company had  net operating  loss carryforwards for
federal income tax  purposes totaling approximately  $16,319,249 which begin  to
expire  in  fiscal  2007.  Operating loss  carryforwards  for  state  income tax
purposes totaling approximately $7,895,167 at March 31, 1996 begin to expire  in
fiscal  1998. Pursuant  to provisions  in the  Tax Reform  Act of  1986, the net
operating loss carryforwards and research and development credits available  for
use  in any given year may be limited  as a result of the significant changes in
stock ownership attributable to the initial public offering.

converted, through a reverse stock split,  into 0.1292 shares of Class A  Common
Stock.
 
    Following  the above Amendment of the Articles of Incorporation, the Company
declared a stock split effected as a stock dividend to the holders of its Common
Stock, providing for the  issuance of approximately 0.1144  shares of Class  E-1
Common  Stock and  0.1144 shares  of Class  E-2 Common  Stock for  each share of
Common Stock held immediately prior to the recapitalization.
 
    As a result  of this  recapitalization and stock  split, each  share of  the
Company's  outstanding Series A Preferred Stock and Series B Preferred Stock was
converted into 0.1292 shares of Class A Common Stock, 0.1144 shares of Class E-1
Common Stock and 0.1144 shares of Class E-2 Common

Stock. Conversion of Series A and Series  B Preferred Stock into Class A  Common
Stock,  Class E-1 Common Stock and Class  E-2 Common Stock was effected upon the
closing of the Company's initial public offering.
 
    On October 20, 1994, the Company voted  to effect a 7:1 reverse stock  split
pursuant  to an amendment of its Articles of Incorporation. As a result thereof,
the shares of Series  A Common Stock,  E-1 Common Stock,  and E-2 Common  Stock,
discussed above, were reduced in number by a factor of 0.7.
 
    STOCK OPTION PLANS AND WARRANTS
 
    The  Company  has  adopted several  stock  option plans  that  authorize the
granting of options to employees, officers and/or consultants to purchase shares
of the Company's Class A Common  Stock. The stock option plans are  administered
by  the Board of Directors  or a committee appointed  by the Board of Directors,
which determines the  terms of the  options, including the  exercise price,  the
number  of shares subject  to option and  the exercisability of  the option. The
options are generally granted at the fair market value of the shares  underlying
the  options at the date of  the grant and expire within  ten years of the grant
date.
 
    In addition  to options  granted pursuant  to the  stock option  plans,  the
Company has issued to certain Board of Directors members, consultants and former
notes  payable  holders warrants  to purchase  shares of  the Company's  Class A
Common Stock.

fiscal years ended March 31, 1995 and 1996 is as follows:

    In  connection  with  the  initial public  offering  in  December,  1994 and
exercise  of  the  underwriter's  over-allotment  option,  the  Company   issued
2,760,000 of each of Class A Warrants and Class B Warrants. Both the Class A and
Class B Warrants will expire in November 1999.
 
    The  Company has  the right,  commencing three  years from  the November 30,
1994, the effective date of the initial  public offering, to redeem the Class  A
and  Class  B  Warrants  at a  price  of  $.05 per  warrant  subject  to certain
conditions regarding the bid price of the Class A Common Stock.
 
    CLASS E-1 AND CLASS E-2 COMMON STOCK
 
    The Company's Class E-1 Common Stock and Class E-2 Common Stock are held  in
escrow,  are not transferable, can  be voted and will  be converted into Class A
Common Stock only  upon the occurrence  of specified events.  All the Class  E-1
Common  Stock shares will  be automatically converted into  Class A Common Stock
shares in the  event that:  (1) the Company's  net income  before provision  for
income  taxes, as defined, amounts  to at least $4,800,000  for the years ending
March 31,  1995  or  1996,  or  at  least  $5,500,000,  $6,850,000,  $8,425,000,
$9,900,000   for  the  fiscal   years  ending  March   31,  1997  through  2000,
respectively, provided  that  if  additional shares  are  issued  earnings  must
increase proportionately; or (2) the closing price, as defined, of the Company's
Class  A Common Stock shall  average in excess of  $15.00 for any 30 consecutive
trading days during the 18 months following the November 30, 1994 effective date
of the Company's initial public offering or average in excess of $19.25 for  any
30  consecutive trading  days during the  period commencing  with the nineteenth
month after November 30, 1994  and ending 36 months from  that date. If none  of
the  above events occur, the Class E-1  Common Stock shares will be cancelled by
the Company on June 30, 2000. All of  the Class E-2 Common Stock shares will  be
automatically  converted into Class A Common Stock shares in the event that: (1)
the Company's net income before provision for income taxes, as defined,  amounts
to  at least $8,625,000 for the years ending  March 31, 1995 or 1996 or at least
$11,800,000, $14,750,000, $20,475,000 or $26,750,000 for the years ending  March
31,  1997 through  2000, respectively,  provided that  if additional  shares are
issued earnings  must increase  proportionally;  or (2)  the closing  price,  as
defined, of the Company's Class A Common Stock shall average in excess of $19.75
for  any 30 consecutive trading days during the 18 months following the November
30, 1994 effective date of the  Company's initial public offering or average  in
excess  of  $24.00  for  any  30  consecutive  trading  days  during  the period
commencing with  the nineteenth  month after  November 30,  1994 and  ending  36
months  from November 30, 1994. If none of the above events occur, the Class E-2
Common Stock shares will be cancelled by the Company on June 30, 2000.
 
    The Company will, in the event of the release of the Class E-1 Common  Stock
and  Class E-2 Common Stock,  recognize during the period  in which the earnings
thresholds are  met or  such  minimum bid  prices  are achieved,  a  substantial
noncash charge to earnings equal to the fair value of such shares on the date of
their  release,  which would  have the  effect  of significantly  increasing the
Company's loss or reducing or eliminating earnings, if any, at such time.
 
17. CONCENTRATION OF CREDIT RISK AND FOREIGN SALES
    The Company generates revenues principally from sales in the medical  field.
As  a result,  the Company's accounts  receivable are  concentrated primarily in
this industry.  In  addition, sales  to  one  customer represented  10%  of  the
Company's   sales  in   fiscal  1996  and   11%  to  a   different  customer  in

    The  Company  performs  ongoing  credit  evaluations  of  its  customers and
generally does not require collateral. Generally, letters of credit are obtained
on international  sales. The  Company maintains  reserves for  potential  credit
losses and such losses have been within management expectations.
 
18. SUBSEQUENT EVENTS
   
    On  June  3, 1996,  the  Company entered  into  a loan  agreement  (the Loan
Agreement) with a  bank which  allows the  Company to  borrow the  lesser of  $1
million or 40% of the market value of the 1,150,000 shares of Mattan Corporation
common  stock (the  Mattan shares) held  by the  Company. Borrowings outstanding
under this loan agreement bear interest at the bank's prime rate (8.25% at  June
3,  1996) plus 1%, are secured  by the Mattan shares and  are due and payable in
November 1996 (see  Note 19  below). The Loan  Agreement also  provides for  the
issuance  of warrants to purchase  9,756 shares of the  Company's Class A Common
Stock at $10.25 per share to the bank.
    
 
19. SUBSEQUENT EVENTS (UNAUDITED)
    The Company has not made the first installment payment under the Pfizer note
payable discussed  in  Note 12  which  was due  in  July 1996.  The  Company  is
attempting to negotiate with Pfizer for an extension of this payment date. There
can  be no assurance  that such extension will  be granted on  this note or that
Pfizer will not seek to enforce its rights on this note.
 
    Effective August 24, 1996, the Company and IBC amended their agreement (Note
6). Pursuant  to  the terms  of  this amendment  the  Company will  (i)  act  as
guarantor of approximately $201,000 of indebtedness owed by IBC to a third party
and  (ii) receive all  proprietary rights, intellectual  property and technology
from IBC used in the manufacturing of argon MOD lasers.
 
   
    On October 9,  1996, the Company  amended the Loan  Agreement extending  the
expiration date of the agreement to April 1997.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Underwriting Agreement (Exhibit 1.1 hereto) provides for indemnification
by the Underwriters of the Registrant and its officers and directors, and by the
Registrant  of  the  Underwriters  for  certain  liabilities  arising  under the
Securities Act or otherwise.
 
   
    The  California   General   Corporation  Laws   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 party 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.   The   Registrant  has   entered  into
indemnification agreements  with  certain of  its  directors and  officers  that
require  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.

the  Registrant's Class A Common  Stock at a weighted  average exercise price of
$4.80 per share. Upon exercise of  these options, the holders will also  receive
2,103 shares of each of Class E-1 Common Stock and Class E-2 Common Stock. These

were  exchanged  for  1,085,000  Class A  Warrants.  The  representative  of the

Stock  to two  affiliates of Mattan  Corporation pursuant to  the Share Exchange

the Registrant of 1,150,000 shares of Mattan Corporation's Common Stock.

involving  a "sale" of  securities as such term  is used in  Section 2(3) of the
Securities Act.

ITEM 28.  UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes that:
 
        (1)  For purposes of determining any liability under the Securities Act,
    the information omitted from  the form of Prospectus  filed as part of  this
    Registration  Statement in reliance upon Rule 430A and contained in the form
    of Prospectus filed by the Registrant  pursuant to Rule 424(b)(1) or (4)  or
    497(h)  under  the  Securities  Act  shall be  deemed  to  be  part  of this
    Registration Statement as of the time it was declared effective.
 
        (2) For purposes of determining any liability under the Securities  Act,
    each  post-effective amendment that  contains a form  of Prospectus shall be
    deemed to be a new Registration Statement relating to the securities offered
    therein, and the offering of such securities at 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 provisions described in Item 24 hereof, or otherwise,
the Registrant  has been  advised that  in  the opinion  of the  Securities  and
Exchange  Commission such indemnification is  against public policy as expressed
in the Securities  Act and  is, therefore, unenforceable.  In the  event that  a
claim  for indemnification against  such liabilities (other  than the payment by
the  Registrant  of  expenses  incurred  or  paid  by  a  director,  officer  or
controlling  person thereof  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 Securities
Act and will be governed by the final adjudication of such issue.

                             UNDERWRITING AGREEMENT


D.H. Blair Investment Banking Corp.                          September ___, 1996
44 Wall Street
New York, New York 10005

   
          Premier Laser Systems, Inc., a California corporation (the 
"Company"), proposes to issue and sell to D.H. Blair Investment Banking Corp. 
(the "Underwriter"), as underwriter pursuant to this Underwriting Agreement 
(the "Agreement"), an aggregate of 11,000 Units, each unit being hereinafter 
referred to as a "Unit" and consisting of 190 shares of Class A Common Stock, 
no par value ("Shares"), and 95 redeemable Class B Warrants (the "Warrants"). 
Each Warrant is exercisable to purchase one share of Class A Common Stock at 
a price of $8.00 from the date of issusance, 1996 to November 30, 1999.  The 
Warrants are subject to redemption, in certain instances commencing November 
30, 1997.  In addition, the Company proposes to grant to the Underwriter the 
option referred to in Section 2(b) to purchase all or any part of an 
aggregate of 1,650 additional Units.  Unless the context otherwise indicates, 
the term "Units" shall include the 1,650 additional Units referred to above.
    

   
          The Class A Common Stock of the Company to be outstanding
after giving effect to the sale of the Shares is herein called the "Common
Stock."  The Shares and Warrants included in the Units (including the Units
which the Underwriter has the option to purchase) are herein collectively called
the "Securities."
    

          You have advised the Company that you desire to purchase the Units. 
The Company confirms the agreements made by it with respect to the purchase of
the Units by you as follows:

          1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
represents and warrants to, and agrees with, the Underwriter that:


<PAGE>

   
               (a)  A registration statement (File No. 333-04219) on Form 
SB-2 relating to the public offering of the Units, including a form of 
prospectus subject to completion, copies of which have heretofore been 
delivered to you, has been prepared by the Company in conformity with the 
requirements of the Securities Act of 1933, as amended (the "Act"), and the 
rules and regulations (the "Rules and Regulations") of the Securities and 
Exchange Commission (the "Commission") thereunder, and has been filed with 
the Commission under the Act and one or more amendments to such registration 
statement may have been so filed.  After the execution of this Agreement, the 
Company will file with the Commission either (i) if such registration 
statement, as it may have been amended, has been declared by the Commission 
to be effective under the Act, a prospectus in the form most recently 
included in an amendment to such registration statement (or, if no such 
amendment shall have been filed, in such registration statement), with such 
changes or insertions as are required by Rule 430A under the Act or permitted 
by Rule 424(b) under the Act, as have been provided to and approved by you 
prior to the execution of this Agreement, or (ii) if such registration 
statement, as it may have been amended, has not been declared by the 
Commission to be effective under the Act, an amendment to such registration 
statement, including a form of prospectus, a copy of which amendment has been 
furnished to and approved by you prior to the execution of this Agreement.  
    

   
          As used in this Agreement, the term "Registration Statement" 
means such registration statement, as amended at the time when it was or is 
declared effective, including all financial schedules and exhibits thereto 
and including any information omitted therefrom pursuant to Rule 430A under 
the Act and included in the Prospectus (as hereinafter defined); the term 
"Preliminary Prospectus" means each prospectus subject to completion filed 
with such registration statement or any amendment thereto (including the 
prospectus subject to completion, if any, included in the Registration 
Statement or any amendment thereto at the time it was or is declared 
effective); the term "Prospectus" means (A) the prospectus first filed with 
the Commission pursuant to Rule 424(b) under the Act or (B) if no prospectus 
is required to be filed pursuant to said Rule 424(b), such term means the 
prospectus included in the Registration Statement; except that if such 
registration statement or prospectus is amended or such prospectus is 
supplemented, after the effective date of such registration statement and 
prior to the Option Closing Date (as hereinafter defined), the terms 
"Registration Statement" and "Prospectus" shall include such registration 
statement and prospectus as so amended, and the term "Prospectus" shall 
include the prospectus as so supplemented, or both, as the case may be.
    

                                       -2-

<PAGE>

   
               (b)  The Commission has not issued any order preventing or 
suspending the use of any Preliminary Prospectus.  At the time the 
Registration Statement becomes effective and at all times subsequent thereto 
up to and on the Closing Date (as hereinafter defined) or the Option Closing 
Date, as the case may be, (i) the Registration Statement and Prospectus will 
in all respects conform to the requirements of the Act and the Rules and 
Regulations; and (ii) neither the Registration Statement nor the Prospectus 
will include any untrue statement of a material fact or omit to state any 
material fact required to be stated therein or necessary to make statements 
therein, in light of the circumstances under which they were made, not 
misleading; provided, however, that the Company makes no representations, 
warranties or agreements as to information contained in or omitted from the 
Registration Statement or Prospectus in reliance upon, and in conformity 
with, written information furnished to the Company by or on behalf of the 
Underwriter specifically for use in the preparation thereof.  It is 
understood that the statements set forth in the Prospectus on page 2 with 
respect to stabilization, under the heading "Risk Factors - Possible Adverse 
Effects of Liquidity of the Company's Securities Due to the Investigation of 
D.H. Blair Corp. and D.H. Blair & Co., Inc. by the Securities and Exchange 
Commission," under the heading "Underwriting" and the identity of counsel to 
the Underwriter under the heading "Legal Matters" constitute the only 
information furnished in writing by or on behalf of the Underwriter for 
inclusion in the Registration Statement and Prospectus, as the case may be.
    

   
               (c)  The Company has been duly incorporated and is validly 
existing as a corporation in good standing under the laws of the State of 
California, with full power and authority (corporate and other) to own its 
properties and conduct its business as described in the Prospectus and is 
duly qualified to do business as a foreign corporation and is in good 
standing in all other jurisdictions in which the nature of its business or 
the character or location of its properties requires such qualification, 
except where failure to so qualify will not materially and adversely affect 
the Company's business, properties or financial condition.
    

               (d)  The authorized, issued and outstanding capital stock of the
Company as of June 30, 1996 is as set forth in the Prospectus under
"Capitalization"; the shares of issued and outstanding capital stock of the
Company set forth thereunder have been duly authorized, validly issued and are
fully paid and non-assessable; except as set forth in the Prospectus, no
options, warrants, or other rights to purchase, agreements or other obligations
to issue, or agreements or other rights to convert any obligation into, any
shares of capital stock of the Company have been granted or entered into by the
Company; and the capital stock conforms to all statements relating thereto
contained in the Registration Statement and Prospectus.

               (e)  The Units and the Shares are duly authorized, and when
issued and delivered pursuant to this Agreement, will be duly authorized,
validly issued, fully paid and nonassessable and free of preemptive rights of
any security holder of the Company.  Neither the 


                                       -3-

<PAGE>

filing of the Registration Statement nor the offering or sale of the Units as
contemplated in this Agreement gives rise to any rights, other than those which
have been waived or satisfied, for or relating to the registration of any shares
of Common Stock, except as described in the Registration Statement.

   
          The Warrants have been duly authorized and, when issued, 
delivered and paid for pursuant to this Agreement, will have been duly 
executed, issued and delivered and will constitute valid and legally binding 
obligations of the Company enforceable in accordance with their terms and 
entitled to the benefits provided by the Warrant Agreement dated November 30, 
1994, as amended, pursuant to which such Warrants are to be issued (the 
"Warrant Agreement"), the amendment to which will be substantially in the 
form filed as an exhibit to the Registration Statement.  The shares of Common 
Stock issuable upon exercise of the Warrants have been reserved for issuance 
upon the exercise of the Warrants and when issued in accordance with the 
terms of the Warrants and Warrant Agreement, will be duly and validly 
authorized, validly issued, fully paid and non-assessable and free of 
preemptive rights and no personal liability will attach to the ownership 
thereof.  The Warrant Agreement has been duly authorized and, when executed 
and delivered pursuant to this Agreement, will have been duly executed and 
delivered and will constitute the valid and legally binding obligation of the 
Company enforceable in accordance with its terms.  The Warrants and the 
Warrant Agreement conform to the respective descriptions thereof in the 
Registration Statement and Prospectus.
    

   
          The Shares and the Warrants contained in the Unit Purchase 
Option have been duly authorized and, when duly issued, delivered and paid 
for, such Warrants will constitute valid and legally binding obligations of 
the Company enforceable in accordance with their terms and entitled to the 
benefits provided by the Unit Purchase Option.  The Shares included in the 
Unit Purchase Option (and the shares of Common Stock issuable upon exercise 
of such Warrants) when issued and sold, will be duly authorized, validly 
issued, fully paid and non-assessable and free of preemptive rights and no 
personal liability will attach to the ownership thereof.
    

   
               (f)  This Agreement, the Unit Purchase Option and the M/A 
Extension Agreement (as defined below) have been duly and validly authorized, 
executed and delivered by the Company.  The Company has full power and lawful 
authority to authorize, issue and sell the Units to be sold by it hereunder 
on the terms and conditions set forth herein, and no consent, approval, 
authorization or other order of any governmental authority is required in 
connection with such authorization, execution and delivery or with the 
authorization, issue and sale of the Units or the Unit Purchase Option, 
except such as may be required under the Act or state securities laws.
    

   
               (g)  Except as described in the Prospectus and for such 
matters as would not have a material adverse effect on the Company's 
business, financial condition or results of operations, the Company is not in 
violation, breach or default of or under, and consummation of the 
transactions herein contemplated and the fulfillment of the terms of this 
Agreement will not conflict with, or result in a breach or violation of, any 
of the terms or provisions of, or constitute a default under, or result in 
the creation or imposition of any lien, charge or encumbrance upon any of the 
property or assets of the Company pursuant to the terms of any indenture, 
mortgage, deed of trust, loan 
    
                                       -4-

<PAGE>

agreement or other agreement or instrument to which the Company is a party or by
which the Company may be bound or to which any of the property or assets of the
Company is subject, nor will such action result in any violation of the
provisions of the articles of incorporation or the by-laws of the Company, as
amended, or any statute or any order, rule or regulation applicable to the
Company of any court or of any regulatory authority or other governmental body
having jurisdiction over the Company.

               (h)  Subject to the qualifications stated in the Prospectus, the
Company has good and marketable title to all properties and assets described in
the Prospectus as owned by it, free and clear of all liens, charges,
encumbrances or restrictions, except such as are not materially significant or
important in relation to its business; all of the material leases and subleases
under which the Company is the lessor or sublessor of properties or assets or
under which the Company holds properties or assets as lessee or sublessee as
described in the Prospectus are in full force and effect, and, except as
described in the Prospectus, the Company is not in default in any material
respect with respect to any of the terms or provisions of any of such leases or
subleases, and no claim has been asserted by anyone adverse to rights of the
Company as lessor, sublessor, lessee or sublessee under any of the leases or
subleases mentioned above, or affecting or questioning the right of the Company
to continued possession of the leased or subleased premises or assets under any
such lease or sublease except as described or referred to in the Prospectus; and
the Company owns or leases all such properties described in the Prospectus as
are necessary to its operations as now conducted and, except as otherwise stated
in the Prospectus, as proposed to be conducted as set forth in the Prospectus.

               (i)  Price Waterhouse LLP, who have given their reports on
certain financial statements filed and to be filed with the Commission as a part
of the Registration Statement, which are incorporated in the Prospectus, are
with respect to the Company, independent public accountants as required by the
Act and the Rules and Regulations.

   
               (j)  The financial statements, together with related notes, 
set forth in the Prospectus (or if the Prospectus is not in existence, the 
most recent Preliminary Prospectus) or the Registration Statement present 
fairly the financial position and results of operations and changes in cash 
flow position of the Company on the basis stated in the Registration 
Statement, at the respective dates and for the respective periods to which 
they apply.  Said statements and related notes have been prepared in 
accordance with generally accepted accounting principles applied on a basis 
which is consistent during the periods involved.  The information set forth 
under the caption "Selected Financial Data" in the Prospectus fairly 
present, on the basis stated in the Prospectus, the information included 
therein.  The pro forma financial information filed as part of the 
Registration Statement or included in the Prospectus (or such preliminary 
prospectus) has been prepared in accordance with the Commission's rules and 
guidelines with respect to pro forma financial statements, and includes all 
adjustments necessary to present fairly the pro forma financial condition and 
results of 
    

                                       -5-

<PAGE>

operations at the respective dates and for the respective periods indicated and
all assumptions used in preparing such pro forma financial statements are
reasonable.

   
               (k)  Subsequent to the respective dates as of which 
information is given in the Registration Statement and Prospectus (or, if the 
Prospectus is not in existence, the most recent Preliminary Prospectus), the 
Company has not incurred any liabilities or obligations, direct or 
contingent, not in the ordinary course of business, or entered into any 
transaction not in the ordinary course of business, which is material to the 
business of the Company, and there has not been any change in the capital 
stock (other than immaterial changes arising from option exercises) of, or 
any incurrence of short-term or long-term debt by, the Company or any 
issuance of options, warrants or other rights to purchase the capital stock 
of the Company or any adverse change or any development involving, so far as 
the Company can now reasonably foresee a prospective adverse change in the 
condition (financial or other), net worth, results of operations, business, 
key personnel or properties of it which would be material to the business or 
financial condition of the Company and the Company has not become a party to, 
and neither the business nor the property of the Company has become the 
subject of, any material litigation whether or not in the ordinary course of 
business.
    

   
               (l)  Except as set forth in the Prospectus, there is not 
now pending or, to the knowledge of the Company, threatened, any action, suit 
or proceeding to which the Company is a party before or by any court or 
governmental agency or body, which might result in any material adverse 
change in the condition (financial or other), business prospects, net worth, 
or properties of the Company, nor are there any actions, suits or proceedings 
related to environmental matters or related to discrimination on the basis of 
age, sex, religion or race; and no labor disputes involving the employees of 
the Company exist or, to the Company's knowledge, are imminent which might be 
expected to adversely affect the conduct of the business, property or 
operations or the financial condition or results of operations of the Company.
    

               (m)  Except as disclosed in the Prospectus, the Company has filed
all necessary federal, state and foreign income and franchise tax returns and
has paid all taxes shown as due thereon; and there is no tax deficiency which
has been or to the knowledge of the Company might be asserted against the
Company.

   
               (n)  The Company has sufficient licenses, permits and other
governmental authorizations currently required for the conduct of its business
or the ownership of its properties as described in the Prospectus, 
except where the failure to obtain such licenses, permits or authorizations 
would not have a material adverse effect on the Company's business, financial 
conditions or results of operations, and the Company is in all
material respects complying therewith and owns or possesses adequate rights to
use all material patents, patent applications, trademarks, service marks,
trade-names, trademark registrations, service mark registrations, copyrights and
licenses necessary for the conduct of such business and had not received any
notice of conflict with the asserted rights of others in respect thereof.  To
the best knowledge of the Company, none of the activities or business of the
Company are in violation of, or cause the Company to violate, any law, rule,
regulation or order of the United States, any state, county or locality, or of
any agency or body of the United States or of any state, county or locality, the
violation of which 
    

                                       -6-

<PAGE>

   
would have a material adverse impact upon the condition (financial or
otherwise), business, property, results of operations, or net worth
of the Company.
    

               (o)  The Company has not, directly or indirectly, at any time
(i) made any contributions to any candidate for political office, or failed to
disclose fully any such contribution in violation of law or (ii) made any
payment to any state, federal or foreign governmental officer or official, or
other person charged with similar public or quasi-public duties, other than
payments or contributions required or allowed by applicable law.  The Company's
internal accounting controls and procedures are sufficient to cause the Company
to comply in all material respects with the Foreign Corrupt Practices Act of
1977, as amended.

               (p)  On the Closing Dates (hereinafter defined) all transfer or
other taxes, (including franchise, capital stock or other tax, other than income
taxes, imposed by any jurisdiction) if any, which are required to be paid in
connection with the sale and transfer of the Units to the Underwriter hereunder
will have been fully paid or provided for by the Company and all laws imposing
such taxes will have been fully complied with.

               (q)  All contracts and other documents of the Company which are,
under the Rules and Regulations, required to be filed as exhibits to the
Registration Statement have been so filed.

               (r)  The Company has not taken and will not take, directly or
indirectly, any action designed to cause or result in, or which has constituted
or which might reasonably be expected to constitute, the stabilization or
manipulation of the price of the shares of Common Stock to facilitate the sale
or resale of the Units hereby.

               (s)  The Company has no subsidiaries.

   
               (t)  The Company has not entered into any agreement pursuant to
which any person is entitled either directly or indirectly to compensation from
the Company for services as a finder in connection with the proposed public
offering, provided, however, the Company may make payments of up to $35,000 to
Rodman & Renshaw, Inc. or its counsel.
    

   
               (u)  Except as previously disclosed in writing by the 
Company to the Underwriter, no officer or director of the Company has any 
affiliation or association with any member of the National Association of 
Securities Dealers Inc.  ("NASD"). 
    

               (v)  The Company is not, and upon receipt of the proceeds from
the sale of the Units will not be, an "investment company" within the meaning of
the Investment Company Act of 1940, as amended, and the rules and regulations
thereunder.

               (w)  The Company has not distributed and will not distribute 
prior to the First Closing Date (as defined below) any offering material in

Prospectus, Prospectus, the Registration Statement or the other materials 
permitted by the Act, if any.
    
               (x)  The conditions for use of Form SB-2, as set forth in the

most recent Preliminary Prospectus) and that have not been so disclosed.
    
               (z)  The Company has complied with all provisions of Section
517.075 Florida Statutes relating to doing business with the government of Cuba
or with any person or affiliate located in Cuba.

          2.   PURCHASE, DELIVERY AND SALE OF THE UNITS.
   
               (a)  Subject to the terms and conditions of this Agreement, and
upon the basis of the representations, warranties, and agreements herein
contained, the Company agrees to issue and sell to the Underwriter, and the
Underwriter agrees to buy from the Company at $925 per Unit, at the place
and time hereinafter specified, 11,000 Units.
    
   
               Delivery of the First Units against payment therefor shall 
take place at the offices of D.H. Blair Investment Banking Corp., 44 Wall 
Street, New York, N.Y.  (or at such other place as may be designated by 
agreement between you and the Company) at 10:00 a.m., New York time, on 
October 18, 1996, or at such later time and date as you may designate, such 
time and date of payment and delivery for the First Units being herein called 
the "First Closing Date."
    
               (b)  In addition, subject to the terms and conditions of this
Agreement, and upon the basis of the representations, warranties and agreements
herein contained, the Company hereby grants an option to the Underwriter to
purchase all or any part of an aggregate of an additional 1,650 Units at the
same price per Unit as the Underwriter shall pay for the First Units being sold
pursuant to the provisions of subsection (a) of this Section 2 (such additional
Units being referred to herein as the "Option Units").  This option may be
exercised within 45 days after the effective date of the Registration Statement
upon notice by you to the Company advising as to the amount of Option Units as
to which the option is being exercised, the names and denominations in which the
certificates for such Option Units are to be registered and the time and date
when such certificates are to be delivered.  Such time and date shall be
determined 


                                       -8-

<PAGE>
   
by you but shall not be earlier than four nor later than ten full business 
days after the exercise of said option, nor in any event prior to the First 
Closing Date, and such time and date is referred to herein as the "Option 
Closing Date." Delivery of the Option Units against payment therefor shall 
take place at the offices of D.H. Blair Investment Banking Corp., 44 Wall 
Street, New York, N.Y. The Option granted hereunder may be exercised only to 
cover overallotments in the sale by the Underwriter of First Units referred 
to in subsection (a) above. In the event the Company declares or pays a 
dividend or distribution on its Common Stock, whether in the form of cash, 
shares of Common Stock or any other consideration, prior to the Option 
Closing Date, such dividend or distribution shall also be paid on the Option 
Units on the Option Closing Date (to the extent the option is exercised).
    
               (c)  The Company will make the certificates for the securities
comprising the Units to be purchased by the Underwriter hereunder available to
you for checking at least two full business days prior to the First Closing Date
or the Option Closing Date (which are collectively referred to herein as the
"Closing Dates").  The certificates shall be in such names and denominations as
you may request, at least two full business days prior to the Closing Dates. 
Time shall be of the essence and delivery at the time and place specified in
this Agreement is a further condition to the obligations of the Underwriter.

               Definitive certificates in negotiable form for the Units to be
purchased by the Underwriter hereunder will be delivered by the Company to you
against payment of the purchase price by the Underwriter, by certified or bank
cashier's checks in New York Clearing House funds, payable to the order of the
Company.

               In addition, in the event the Underwriter exercises the option to
purchase from the Company all or any portion of the Option Units pursuant to the
provisions of subsection (b) above, payment for such Units shall be made to or
upon the order of the Company by certified or bank cashier's checks payable in
New York Clearing House funds at the offices of D.H. Blair Investment Banking
Corp., at the time and date of delivery of such Units as required by the
provisions of subsection (b) above, against receipt of the certificates for such
Units by the Underwriter for the account of the Underwriter registered in such
names and in such denominations as the Underwriter may request.

               It is understood that the Underwriter proposes to offer the Units
to be purchased hereunder to the public upon the terms and conditions set forth
in the Registration Statement, after the Registration Statement becomes
effective.

          3.   COVENANTS OF THE COMPANY.  The Company covenants and agrees with
the Underwriter that:

   
               (a)  The Company will use its best efforts to cause the
Registration Statement to become effective as promptly as possible.  If
required, the Company will file the Prospectus that constitutes a part 
thereof and any amendment or supplement 
    


                                       -9-

<PAGE>
   
thereto with the Commission in the manner and within the time period required 
by 424(b) under the Act.  Upon notification from the Commission that the 
Registration Statement has become effective, the Company will so advise you 
and will not at any time, whether before or after the effective date, file 
the Prospectus or any amendment to the Registration Statement or supplement 
to the Prospectus of which you shall not previously have been advised and 
furnished with a copy or to which you or your counsel shall have objected in 
writing or which is not in compliance with the Act and the Rules and 
Regulations.  At any time prior to the later of (A) the completion by the 
Underwriter of the distribution of the Units contemplated hereby (but in no 
event more than nine months after the date on which the Registration 
Statement shall have become or been declared effective) and (B) 25 days after 
the date on which the Registration Statement shall have become or been 
declared effective, the Company will prepare and file with the Commission, 
promptly upon your request, any amendments or supplements to the Registration 
Statement or Prospectus which, in your opinion, may be necessary or advisable 
in connection with the distribution of the Units.
    
               As soon as the Company is advised thereof, the Company will
advise you, and confirm the advice in writing, of the receipt of any comments of
the Commission, of the effectiveness of any post-effective amendment to the
Registration Statement, of the filing of any supplement to the Prospectus or any
amended Prospectus, of any request made by the Commission for amendment of the
Registration Statement or for supplementing of the Prospectus or for additional
information with respect thereto, of the issuance by the Commission or any state
or regulatory body of any stop order or other order or threat thereof suspending
the effectiveness of the Registration Statement or any order preventing or
suspending the use of any preliminary prospectus, or of the suspension of the
qualification of the Units for offering in any jurisdiction, or of the
institution of any proceedings for any of such purposes, and will use its best
efforts to prevent the issuance of any such order, and, if issued, to obtain as
soon as possible the lifting thereof.

               The Company has caused to be delivered to you copies of each
Preliminary Prospectus, and the Company has consented and hereby consents to the
use of such copies for the purposes permitted by the Act.  The Company
authorizes the Underwriter and dealers to use the Prospectus in connection with
the sale of the Units for such period as in the opinion of counsel to the
Underwriter the use thereof is required to comply with the applicable provisions
of the Act and the Rules and Regulations.  In case of the happening, at any time
within such period as a Prospectus is required under the Act to be delivered in
connection with sales by an underwriter or dealer of any event of which the
Company has knowledge and which materially affects the Company or the securities
of the Company, or which in the opinion of counsel for the Company or counsel
for the Underwriter should be set forth in an amendment of the Registration
Statement or a supplement to the Prospectus in order to make the statements
therein not then misleading, in light of the circumstances existing at the time
the Prospectus is required to be delivered to a purchaser of the Units or in
case it shall be necessary to amend or supplement the Prospectus to comply with
law or with the Rules and Regulations, the Company 


                                      -10-

<PAGE>

will notify you promptly and forthwith prepare and furnish to you copies of such
amended Prospectus or of such supplement to be attached to the Prospectus, in
such quantities as you may reasonably request, in order that the Prospectus, as
so amended or supplemented, will not contain any untrue statement of a material
fact or omit to state any material facts necessary in order to make the
statements in the Prospectus, in the light of the circumstances under which they
are made, not misleading.  The preparation and furnishing of any such amendment
or supplement to the Registration Statement or amended Prospectus or supplement
to be attached to the Prospectus shall be without expense to the Underwriter,
except that in case any Underwriter is required, in connection with the sale of
the Units to deliver a Prospectus nine months or more after the effective date
of the Registration Statement, the Company will upon request of and at the
expense of the Underwriter, amend or supplement the Registration Statement and
Prospectus and furnish the Underwriter with reasonable quantities of
prospectuses complying with Section 10(a)(3) of the Act.

               The Company will comply with the Act, the Rules and Regulations
and the Securities Exchange Act of 1934 and the rules and regulations thereunder
in connection with the offering and issuance of the Units.

               (b)  The Company will use its best efforts to qualify to register
the Units for sale under the securities or "blue sky" laws of such jurisdictions
as the Underwriter may designate and will make such applications and furnish
such information as may be required for that purpose and to comply with such
laws, provided the Company shall not be required to qualify as a foreign
corporation or a dealer in securities or to execute a general consent of service
of process in any jurisdiction in any action other than one arising out of the
offering or sale of the Units.  The Company will, from time to time, prepare and
file such statements and reports as are or may be required to continue such
qualification in effect for so long a period as the Underwriter may reasonably
request.
   
               (c)  If the sale of the Units provided for herein is not 
consummated for any reason caused by the Company, the Company shall pay all 
costs and expenses incident to the performance of the Company's obligations 
hereunder, including but not limited to, all of the expenses itemized in 
Section 8, including the accountable expenses of the Underwriter, up to the 
maximum set forth in Section 8(b).
    
   
               (d)  The Company will use its best efforts if requested by the 
Underwriter and to obtain and keep current a listing in the Standard & Poors 
or Moody's Industrial OTC Manual.
    
               (e)  For so long as the Company is a reporting company under
either Section 12(g) or 15(d) of the Securities Exchange Act of 1934, the
Company, at its expense, will furnish to its stockholders an annual report
(including financial statements audited by independent public accountants), in
reasonable detail and at its expense, will furnish to you during the period
ending five (5) years from the date hereof, (i) as soon as practicable after the


                                      -11-

<PAGE>

end of each fiscal year, a balance sheet of the Company and any of its
subsidiaries as at the end of such fiscal year, together with statements of
income, surplus and cash flow of the Company and any subsidiaries for such
fiscal year, all in reasonable detail and accompanied by a copy of the
certificate or report thereon of independent accountants; (ii) as soon as
practicable after the end of each of the first three fiscal quarters of each
fiscal year, consolidated summary financial information of the Company for such
quarter in reasonable detail; (iii) as soon as they are available, a copy of all
reports (financial or other) mailed to security holders; (iv) as soon as they
are available, a copy of all non-confidential reports and financial statements
furnished to or filed with the Commission or any securities exchange or
automated quotation system on which any class of securities of the Company is
listed; and (v) such other information as you may from time to time reasonably
request.

               (f)  In the event the Company has an active subsidiary or
subsidiaries, such financial statements referred to in subsection (e) above will
be on a consolidated basis to the extent the accounts of the Company and its
subsidiary or subsidiaries are consolidated in reports furnished to its
stockholders generally.
   
               (g)  The Company will deliver to you at or before the First 
Closing Date two signed copies of the Registration Statement including all 
financial statements and exhibits filed therewith, and of all amendments 
thereto, and will deliver to the Underwriter such number of conformed copies 
of the Registration Statement, including such financial statements but 
without exhibits, and of all amendments thereto, as the Underwriter may 
reasonably request.  The Company will deliver to or upon the order of the 
Underwriter, from time to time until the effective date of the Registration 
Statement, as many copies of any Preliminary Prospectus filed with the 
Commission prior to the effective date of the Registration Statement as the 
Underwriter may reasonably request.  The Company will deliver to the 
Underwriter on the effective date of the Registration Statement and 
thereafter for so long as a Prospectus is required to be delivered under the 
Act, from time to time, as many copies of the Prospectus, in final form, or 
as thereafter amended or supplemented, as the Underwriter may from time to 
time reasonably request.  The Company, not later than 10:00 a.m., New York 
City time, on the business day after the date of determination of the public 
offering price, on such date, will deliver to the Underwriter, without charge, 
as many copies of the Prospectus and any amendment or supplement thereto as 
the Underwriter may reasonably request for purposes of confirming orders that 
are expected to settle on the First Closing Date.
    
               (h)  The Company will make generally available to its security
holders and to the registered holders of its Warrants and deliver to you as soon
as it is practicable to do so but in no event later than 90 days after the end
of twelve months after its current fiscal quarter, an earnings statement (which
need not be audited) covering a period of at least 12 consecutive 


                                      -12-

<PAGE>

months beginning after the effective date of the Registration Statement, which
shall satisfy the requirements of Section 11(a) of the Act.
   
               (i)  The Company will apply the net proceeds from the sale of the
Units for the purposes set forth under "Use of Proceeds" in the Prospectus.
    
               (j)  The Company will, promptly upon your request, prepare and
file with the Commission any amendments or supplements to the Registration
Statement, Preliminary Prospectus or Prospectus and take any other action, which
in the reasonable opinion of Bachner, Tally, Polevoy & Misher LLP, counsel to
the Underwriter, may be reasonably necessary or advisable in connection with the
distribution of the Units, and will use its best efforts to cause the same to
become effective as promptly as possible.

               (k)  The Company will reserve and keep available that maximum
number of its authorized but unissued securities which are issuable upon
exercise of the Unit Purchase Option outstanding from time to time.
   
               (l)  The Company has obtained agreements from each officer, 
director and beneficial holder of more than 1% of the Company's outstanding 
capital stock known to the Company after due inquiry (the "Principal 
Stockholders") providing that they will not directly or indirectly, offer, 
sell (including any short sale), grant any option for the sale of, acquire 
any option to dispose of, or otherwise dispose of any shares of Common Stock 
for a period of 13 months from the First Closing Date without the prior 
written consent of the Underwriter.  In order to enforce this covenant, the 
Company shall impose stop-transfer instructions with respect to the shares 
owned by the Principal Stockholders until the end of such period.
    
               (m)  Prior to completion of this offering, the Company will make
all filings required, including registration under the Securities Exchange Act
of 1934, to obtain the additional listing of the Common Stock and Warrants on
the Nasdaq National Market (or a listing on such other market or exchange as the
Underwriter consents to), and will effect and maintain such listing for at least
five years from the date of this Agreement.
   
               (n)  The Company represents that it has not taken and agrees 
that it or he will not take, directly or indirectly, any action designed to 
or which has constituted or which might reasonably be expected to cause or 
result in the stabilization or manipulation of the price of the Units, Shares 
or the Warrants or to facilitate the sale or resale of the Securities. The 
Principal Stockholders will confirm the foregoing on their own behalf in 
letters delivered to the Company.
    
               (o)  On the Closing Date and simultaneously with the delivery of
the Units, the Company shall execute and deliver to you the Unit Purchase
Option.  The Unit 


                                      -13-

<PAGE>

Purchase Option will be substantially in the form of the Underwriter's Unit
Purchase Option filed as an Exhibit to the Registration Statement.
   
               (p)  During the three year period from the First Closing Date, 
the Company will not, without the prior written consent of the Underwriter, 
offer or sell any of its securities pursuant to Regulation S under the Act.
    
               (q)  The Company will not, without the prior written consent of
the Underwriter, grant registration rights to any person which are exercisable
sooner than 13 months from the First Closing Date.

               (r)  Colette Cozean, Ph.D. shall be President and Director of
Research and T. Daniel Caruso, Jr. shall be Senior Vice President, Sales and
Marketing of the Company on the Closing Dates.  The Company has obtained key
person life insurance on the life of Dr. Cozean in an amount of not less than $3
million and will use its best efforts to maintain such insurance for either
three years from the First Closing Date or the term of her employment agreement,
whichever is longer unless her employment with the Company is earlier
terminated.  In such event, the Company will obtain a comparable policy on the
life of her successor for the balance of the said period.  For a period of 13
months from the First Closing Date, the compensation of the executive officers
of the Company shall not be increased from the compensation levels disclosed in
the Prospectus provided that the Company may pay accrued bonuses to executive
officers in the aggregate amount of $22,000 previously approved by the Company's
board of directors.

               (s)  On the Closing Date and simultaneously with the delivery of
the Units the Company shall execute and deliver to you, an extension to the
agreement with you, dated as of December 7, 1994, regarding mergers,
acquisitions, joint ventures and certain other forms of transactions, in the
form previously delivered to the Company by you (the "M/A Extension Agreement").

               (t)  So long as any Warrants are outstanding, the Company shall
use its best efforts to cause post-effective amendments to the Registration
Statement to become effective in compliance with the Act and without any lapse
of time between the effectiveness of any such post-effective amendments and
cause a copy of each Prospectus, as then amended, to be delivered to each holder
of record of a Warrant and to furnish to each Underwriter and dealer as 


                                      -14-

<PAGE>

many copies of each such Prospectus as such Underwriter or dealer may reasonably
request.  The Company shall not call for redemption any of the Warrants unless a
registration statement covering the securities underlying the Warrants has been
declared effective by the Commission and remains current at least until the date
fixed for redemption.  In addition, for so long as any Warrant is outstanding,
the Company will promptly notify the Underwriter of any material change in the
business, financial condition or prospects of the Company.
   
               (u)  Upon the exercise of any Warrant or Warrants after 
October 15, 1997, the Company will pay D.H. Blair Investment Banking Corp., a 
fee of 5% of the aggregate exercise price of the Warrants, of which a portion 
may be reallowed to the dealer who solicited the exercise (which may also be 
D.H. Blair Investment Banking Corp. if (i) the market price of the Company's 
Common Stock is greater than the exercise price of the Warrants on the date 
of exercise; (ii) the exercise of the Warrant was solicited by a member of 
the National Association of Securities Dealers, Inc., (iii) the Warrant is 
not held in a discretionary account; (iv) the disclosure of compensation 
arrangements has been made in documents provided to customers, both as part 
of the original offering and at the time of exercise, and (v) the 
solicitation of the Warrant was not in violation of Rule 10b-6 promulgated 
under the Securities Exchange Act of 1934, as amended.  The Company agrees 
not to solicit the exercise of any Warrants other than through D.H. Blair 
Investment Banking Corp. and will not authorize any other dealer to engage in 
such solicitation without the prior written consent of D.H. Blair Investment 
Banking Corp.
    
   
               (v)  For a period of five (5) years from the Effective Date the
Company (i) at its expense, shall cause its regularly engaged independent
certified public accountants to read and comment upon the Company's financial
statements for each of the first three (3) fiscal quarters prior to the
announcement of quarterly financial information, the filing of the Company's
10-Q quarterly report and the mailing of quarterly financial information to
stockholders and (ii) shall not change its accounting firm without the prior
written consent of the Chairman or the President of the Underwriter, which 
shall not be unreasonably withheld.
    
               (w)  As promptly as practicable after the Closing Date, the
Company will prepare, at its own expense, hard cover "bound volumes" relating to
the offering, and will distribute at least four of such volumes to the
individuals designated by the Underwriter or counsel to the Underwriter.
   
               (x)  For a period of five years from the First Closing Date 
(i) the Underwriter shall have the right, but not the obligation, to 
designate two directors of the Board of Directors of the Company which 
designee shall be reasonably acceptable to the Company, and (ii) the Company 
shall engage a public relations firm acceptable to the Underwriter. The

          4.   CONDITIONS OF THE UNDERWRITER'S OBLIGATION.  The obligations of
the Underwriter to purchase and pay for the Units which they have respectively
agreed to purchase hereunder, are subject to the accuracy (as of the date
hereof, and as of the Closing Dates) of and compliance with the representations
and warranties of the Company herein, to the performance by the Company of its
obligations hereunder, and to the following conditions:

               (a)  The Registration Statement shall have become effective and
          you shall have received notice thereof not later than 10:00 A.M., New
          York time, on the date on which the amendment to the registration
          statement originally filed with respect to the Units or to the
          Registration Statement, as the case may be, containing information
          regarding the initial public offering price of the Units has been
          filed with the Commission, or such later time and date as shall have
          been agreed to by the Underwriter; if required, the Prospectus or any
          Term Sheet that constitutes a part thereof and any amendment or
          supplement thereto shall have been filed with the Commission in the
          manner and within the time period required by Rule 434 and 424(b)
          under the Act; on or prior to the Closing Dates no stop order
          suspending the effectiveness of the Registration Statement shall have
          been issued and no proceedings for that or a similar purpose shall
          have been instituted or shall be pending or, to your knowledge or to
          the knowledge of the Company, shall be contemplated by the Commission;
          any request on the part of the Commission for additional information
          shall have been complied with to the reasonable satisfaction of
          Bachner, Tally, Polevoy & Misher LLP, counsel to the Underwriter;

               (b)  At the First Closing Date, you shall have received the
          opinion, dated as of the First Closing Date, of Rutan & Tucker, LLP,
          counsel for the Company, in form and substance satisfactory to counsel
          for the Underwriter, to the effect that:
   
                    (i)   the Company has been duly incorporated and is validly
               existing as a corporation in good standing under the laws of the
               State of California, with full corporate power and authority to
               own its properties and conduct its business as described in the
               Registration Statement and Prospectus and is duly qualified or
               licensed to do business as a foreign corporation and is in good
               standing in each other jurisdiction in which the ownership or 
               leasing of its properties or where the conduct of its business
               requires such qualification, except where the failure to so 
               qualify or be licensed would not have a material adverse 
               effect on the business and condition (financial or otherwise) 
               of the Company;

<PAGE>
   
                  (ii)   to the best knowledge of such counsel, (a) the 
               Company has obtained or is in the process of obtaining, all 
               material governmental licenses, permits and governmental 
               authorizations (collectively "Licenses") necessary to the 
               conduct of its business other than Licenses required under 
               federal or state laws relating to the manufacture or sale of 
               medical devices or relating to the issuance, scope, terms or 
               enforceability of patents, patent applications or copyrights, 
               concerning which such counsel need express no opinion; and (b) 
               all of such Licenses (other than those excluded under the 
               foregoing clause) are in full force and effect;
    
   
                  (iii)  the authorized capitalization of the Company as of 
               June 30, 1996 is as set forth under "Capitalization" in the 
               Prospectus; all shares of the Company's outstanding stock 
               requiring authorization for issuance by the Company's board of 
               directors have been duly authorized, validly issued, are fully 
               paid and non-assessable and conform to the description thereof 
               contained in the Prospectus under the heading "Description of 
               Securities. Except for shares covered by options to purchase 
               13,243 shares of Class A Common Stock issued in January 1993 
               and February 1993, concerning which such counsel need express 
               no opinion, none of the issued shares of capital stock of the 
               Company have been issued in violation of the preemptive rights 
               of any shareholder of the Company. The shareholders of the 
               Company do not have any preemptive rights under the Company's 
               Articles of Incorporation, any Material Contract or California
               law to subscribe for or purchase, any of the Securities offered
               under the Prospectus. The Class A Common Stock, the Warrants, the
               Unit Purchase Option and the Warrant Agreement conform to the 
               respective descriptions thereof contained in the Prospectus 
               under the heading "Description of Securities." The Shares and 
               the shares of Class A Common Stock to be issued upon exercise 
               of the Warrants and the Unit Purchase Option in accordance 
               with the terms of the Warrants, the Warrant Agreement and Unit 
               Purchase Option, have been duly authorized and reserved for 
               issuance and, when issued and delivered, will be validly 
               issued, fully paid and non-assessable and not subject to, 
               preemptive rights, and no personal liability will attach to 
               the ownership thereof. All offers and sales of Securities by 
               the Company since December 7, 1994 were either registered 
               under the Act and applicable state securities laws or exempt 
               from registration requirements; a sufficient number of shares 
               of Common Stock has been reserved for issuance upon exercise 
               of the Warrants and Unit Purchase Option and to the best of 
               such counsel's knowledge, neither the filing of the 
               Registration Statement nor the offering or sale of the Units 
               as contemplated by this Agreement gives rise to any rights, 
               other than those which have been waived or satisfied for or 
               relating to the registration of any shares of Common Stock;
    
                   (iv)   this Agreement, the Unit Purchase Option, the Warrant
               Agreement and the M/A Extension Agreement have been duly and
               validly authorized, executed and delivered by the Company and,
               assuming due execution by each other party hereto or thereto,
               each constitutes a legal, 


                                      -17-

               valid and binding obligation of the Company enforceable against
               the Company in accordance with its respective terms (except as
               such enforceability may be limited by applicable bankruptcy,
               insolvency, reorganization, moratorium or other laws of general
               application relating to or affecting enforcement of creditors'
               rights and the application of equitable principles in any action,
               legal or equitable, and subject to limitations on the 
               enforceability of any indemnification and contribution 
               provisions under applicable law or public policy (such laws, 
               principles and limitations being referred to herein as the 
               "Enforceability Limitations");
    
   
                   (v)   the certificates evidencing the shares of Common Stock
               comply with the California General Corporation Law; subject to 
               the Enforceability Limitations, the Warrants will be
               exercisable for shares of Common Stock of the Company in
               accordance with the terms of the Warrants and at the prices
               therein provided for;
    
   
                  (vi)   other than as set forth in the Prospectus, such 
               counsel knows of no pending or threatened legal or 
               governmental proceedings to which the Company is a party which 
               might materially and adversely affect the business, property, 
               financial condition or operations of the Company; or which 
               question the validity of the Securities, this Agreement, the 
               Warrant Agreement, the Unit Purchase Option or the M/A 
               Extension Agreement except with respect to federal or state 
               governmental proceedings or relations relating to the 
               manufacture or sale of medical devices or relating to the 
               issuance, scope, terms or enforceability of patents, patent 
               applications on copyrights, concerning which such counsel 
               need express no opinion, or of any action taken or to be taken 
               by the Company pursuant to this Agreement, the Warrant 
               Agreement, the Unit Purchase Option or the M/A Extension 
               Agreement; and no such proceedings are known to such counsel 
               to be contemplated against the Company; there are no 
               governmental proceedings or regulations required to be 
               described or referred to in the Registration Statement which 
               are not so described or referred to;
    
   
                   (vii)   to the best of such counsel's knowledge, neither 
               the execution and delivery of this Agreement, the Unit 
               Purchase Option, the Warrant Agreement or the M/A Extension 
               Agreement, nor compliance with the terms hereof or thereof, 
               nor the consummation of the transactions contemplated hereby 
               or thereby, will result in a breach of, or constitute a 
               default under the Articles of Incorporation or Bylaws of the 
               Company, or any Material Contract, or violate any applicable 
               California or federal law, rule, regulation or, to the best of 
               such counsel's knowledge, any order, writ, injunction or 
               decree of any governmental agency or court having jurisdiction 
               over the Company or any of its properties or business;

<PAGE>
   
    
                  (viii)   the Registration Statement has become effective
               under the Act, and to the best of such counsel's knowledge, no
               stop order suspending the effectiveness of the Registration
               statement is in effect, and no proceedings for that purpose have
               been instituted or are pending before, or threatened by, the
               Commission; the Registration Statement and the Prospectus (except
               for the financial statements and other financial data contained
               therein, or omitted therefrom, as to which such counsel need
               express no opinion) comply as to form in all material respects
               with the applicable requirements of the Act and the Rules and
               Regulations;

                  (ix)   such counsel has participated in the preparation of the
               Registration Statement and the Prospectus and nothing has come to
               the attention of such counsel to cause such counsel to have
               reason to believe that the Registration Statement or any
               amendment thereto at the time it became effective or as of the
               Closing Dates contained any untrue statement of a material fact
               required to be stated therein or omitted to state any material
               fact required to be stated therein or necessary to make the
               statements therein not misleading or that the Prospectus or any
               supplement thereto contains any untrue statement of a material
               fact or omits to state a material fact necessary in order to make
               statements therein, in light of the circumstances under which
               they were made, not misleading (except, in the case of both the
               Registration Statement and any amendment thereto and the
               Prospectus and any supplement thereto, for the financial
               statements, notes thereto and other financial information and
               schedules contained therein, as to which such counsel need
               express no opinion);

                   (x)   all descriptions in the Registration Statement and the
               Prospectus, and any amendment or supplement thereto, of contracts
               and other documents are accurate and fairly present the
               information required to be shown, and such counsel is familiar
               with all contracts and other documents referred to in the
               Registration Statement and the Prospectus and any such amendment
               or supplement or filed as exhibits to the Registration Statement,
               and such counsel does not know of any contracts or documents of a
               character required to be summarized or described therein or to be
               filed as exhibits thereto which are not so summarized, described
               or filed;

                  (xi)   no authorization, approval, consent, or license of any
               governmental or regulatory authority or agency is necessary in
               connection with the authorization, issuance, transfer, sale or
               delivery of the Units by the Company, in connection with the
               execution, delivery and performance of this Agreement by the
               Company or in connection with the taking of any action
               contemplated herein, or the issuance of the Unit Purchase Option
               or the Securities underlying the Unit Purchase Option, other than
               registrations or qualifications of the Units under applicable
               state or foreign securities or Blue Sky laws and registration
               under the Act;
   
                   (xii)   the statements set forth under the headings 
               "Business," "Use of Proceeds," "Management," and "Description 
               of Securities" in the Prospectus, insofar as such statements 
               purport to summarize agreements, statutes, licenses, rules or 
               regulations statements of law or legal conclusions, are a fair 
               summary of such agreements, statutes, licenses, rules or 
               regulations, statements of law or legal conclusions, except 
               with respect to matters relating to federal or state 
               regulation of the manufacture or sale of medical devices, or 
               to the issuance, scope, terms or enforceability of patents, 
               patent applications or copyrights; 
    
                   (xiii)   the Common Stock and the Warrants are covered by an
               additional listing application filed with the Nasdaq National
               Market; and 

                   (xiv)   to such counsel's knowledge, there are no business
               relationships or related-party transactions of the nature
               described in Item 404 of Regulation S-K involving the Company and
               any person described in such Item that are required to be
               disclosed in the Prospectus and which have not been so disclosed.
   
                 (c)     At the First Closing Date, you shall have received the
          opinion, addressed to the Underwriter, dated as of the First Closing
          Date, of Knobbe, Martens, Olson & Bear, LLP, patent counsel to the
          Company, substantially in the form set forth in the opinion dated 
          September 4, 1996 to Rodman & Renshaw, Inc. with the following 
          addition:

    
   
    
                                      -20-

<PAGE>

   
               such counsel has conducted a search for existing United States 
               and foreign patents with claims that might cover the Company's
               technology particularly as it relates to medical lasers and
               fiberoptic delivery systems used in dental, ophthalmic and
               surgical applications and, in such counsel's opinion, neither the
               Company's technology or products infringe any United States or
               foreign patents.
    

               (d)   At the First Closing Date, you shall have received an
opinion of Hogan & Hartson L.L.P., regulatory counsel for the Company, addressed
to the Underwriter and dated the First Closing Date, in form and substance
satisfactory to counsel to the Underwriter to the effect that:

            (i)     The statements in the Prospectus under the captions "Risk
          Factors -- Need for FDA and Foreign Government Approvals; Government
          Regulation" 


                                      -21-

<PAGE>

          and "Business -- Government Regulation,"  insofar as such statements
          purport to summarize applicable provisions of the FDC Act and the
          regulations promulgated thereunder, have been reviewed by us and are
          accurate summaries in all material respects of the provisions of such
          statute and regulations purported to be summarized under such captions
          in the Prospectus.

             (ii)   During the course of preparation of the Registration
          Statement, we participated in certain discussions with officers and
          other representatives of the Company as to the FDA matters dealt with
          under the above-referenced captions in the Prospectus.  While we have
          not undertaken to determine independently, and, except as specifically
          provided in the immediately preceding paragraph, we do not assume any
          responsibility for the accuracy, completeness, or fairness of the
          statements in such captioned sections, we may state on the basis of
          these discussions and our review of the documents referenced above
          that no facts have come to our attention which cause us to believe
          that the information contained under the captions "Risk Factors --
          Need for FDA and Foreign Governmental Approvals; Government
          Regulation" and "Business -- Government Regulation" in the Prospectus,
          insofar as such information related to FDA matters, at the time the
          Registration Statement became effective, contained an untrue statement
          of a material fact or omitted to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading, or as of the date hereof, contains an untrue statement of
          a material fact or omits to state a material fact necessary in order
          to make the statements therein, in the light of the circumstances
          under which they were made, not misleading.

          Such opinions shall also cover such matters incident to the
transactions contemplated hereby as the Underwriter or counsel for the
Underwriter shall reasonably request.  In rendering such opinion, such counsel
may rely upon certificates of any officer of the Company or public officials as
to matters of fact; and may rely as to all matters of law other than the law of
the United States or of the State of California upon opinions of counsel
satisfactory to you, in which case the opinion shall state that they have no
reason to believe that you and they are not entitled to so rely.

               (e)  All corporate proceedings and other legal matters relating
to this Agreement, the Registration Statement, the Prospectus and other related
matters shall be satisfactory to or approved by Bachner, Tally, Polevoy &
Misher LLP, counsel to the Underwriter, and you shall have received from such
counsel a signed opinion, dated as of the First Closing Date, with respect to
the validity of the issuance of the Units, the form of the Registration
Statement and Prospectus (other than the financial statements and other
financial data contained therein), the execution of this Agreement and other
related matters as you may reasonably require.  The Company shall have furnished
to counsel for the Underwriter such 


                                      -22-

<PAGE>

documents as they may reasonably request for the purpose of enabling them to
render such opinion.

               (f)  You shall have received a letter prior to the effective date
of the Registration Statement and again on and as of the First Closing Date from
Price Waterhouse LLP, independent public accountants for the Company,
substantially in the form approved by you, and including estimates of the
Company's revenues and results of operations for the period ending at the end of
the month immediately preceding the effective date and results of the comparable
period during the prior fiscal year.

   
               (g)  At the Closing Dates, (i) the representations and 
warranties of the Company contained in this Agreement shall be true and 
correct in all material respects with the same effect as if made on and as of 
the Closing Dates and the Company shall have performed all of its obligations 
hereunder and satisfied all the conditions on its part to be satisfied at or 
prior to such Closing Date; (ii) the Registration Statement and the 
Prospectus and any amendments or supplements thereto shall contain all 
statements which are required to be stated therein in accordance with the Act 
and the Rules and Regulations, and shall in all material respects conform to 
the requirements thereof, and neither the Registration Statement nor the 
Prospectus nor any amendment or supplement thereto shall contain any untrue 
statement of a material fact or omit to state any material fact required to

the circumstances under which they were made, not misleading; (iii) there 
shall have been, since the respective dates as of which information is given, 
no material adverse change, or any development involving a prospective 
material adverse change, in the business, properties, condition (financial or 
otherwise), results of operations, capital stock, long-term or short-term 
debt or general affairs of the Company from that set forth in the 
Registration Statement and the Prospectus, except changes which the 
Registration Statement and Prospectus indicate might occur after the 
effective date of the Registration Statement, and the Company shall not have 
incurred any material liabilities or entered into any agreement not in the 
ordinary course of business other than as referred to in the Registration 
Statement and Prospectus; and (iv) except as set forth in the Prospectus, no 
action, suit or proceeding at law or in equity shall be pending, or to the 
Company's knowledge, threatened against the Company which would be 
required to be set forth in the Registration Statement, and no proceedings 
shall be pending or threatened against the Company before or by any 
commission, board or administrative agency in the United States or elsewhere, 
wherein an unfavorable decision, ruling or finding would materially and 
adversely affect the business, property, condition (financial or otherwise), 
results of operations or general affairs of the Company, and (v) you shall 
have received, at the First Closing Date, a certificate signed by each of the

be subject (as of the date hereof and as of the Option Closing Date) to the
following additional conditions:

                 (i)     The Registration Statement shall remain effective at
               the Option Closing Date, and no stop order suspending the
               effectiveness thereof shall have been issued and no proceedings
               for that purpose shall have been instituted or shall be pending,
               or, to your knowledge or the knowledge of the Company, shall be
               contemplated by the Commission, and any reasonable request on the
               part of the Commission for additional information shall have been
               complied with to the satisfaction of Bachner, Tally, Polevoy &
               Misher LLP, counsel to the Underwriter.

                (ii)     At the Option Closing Date there shall have been
               delivered to you the signed opinions of Rutan & Tucker LLP,
               Knobbe, Martens, Olson & Bear, LLP, and Hogan & Hartson L.L.P.,
               counsel for the Company, dated as of the Option Closing Date, in
               form and substance satisfactory to Bachner, Tally, Polevoy &
               Misher LLP, counsel to the Underwriter, which opinion shall be
               substantially the same in scope and substance as the opinion
               furnished to you at the First Closing Date pursuant to
               Sections 4(b), 4(c) and 4(d) hereof, respectively, except that
               such opinion, where appropriate, shall cover the Option Units.

               (iii)     At the Option Closing Date there shall have been
               delivered to you a certificate of the Chairman of the Board or
               the President and the principal financial or accounting officer

               substance satisfactory to Bachner, Tally, Polevoy & Misher LLP,
               counsel to the Underwriter, substantially the same in scope and
               substance as the certificate furnished to you at the First
               Closing Date pursuant to Section 4(g) hereof.

                (iv)     At the Option Closing Date there shall have been
               delivered to you a letter in form and substance satisfactory to
               you from Price Waterhouse LLP, dated the Option Closing Date and
               addressed to the Underwriter confirming the information in their
               letter referred to in Section 4(f) hereof and stating that
               nothing has come to their attention during the period from the
               ending date of their review referred to in said letter to a date
               not more than five business days prior to the Option Closing
               Date, which would require any change in said letter if it were
               required to be dated the Option Closing Date.

                 (v)     All proceedings taken at or prior to the Option Closing
               Date in connection with the sale and issuance of the Option Units
               shall be 


                                      -24-

<PAGE>

               satisfactory in form and substance to you, and you and Bachner,
               Tally, Polevoy & Misher LLP, counsel to the Underwriter, shall
               have been furnished with all such documents, certificates, and
               opinions as you may request in connection with this transaction
               in order to evidence the accuracy and completeness of any of the
               representations, warranties or statements of the Company or its
               compliance with any of the covenants or conditions contained
               herein.

   
               (g)  No action shall have been taken by the Commission or the
NASD the effect of which would make it improper, at any time prior to the
Closing Date, for members of the NASD to execute transactions (as principal or
agent) in the Units, Common Stock or the Warrants and no proceedings for the
taking of such action shall have been instituted or shall be pending, or, to the
knowledge of the Underwriter or the Company, shall be contemplated by the
Commission or the NASD.  The Company represents that at the date hereof it has
no knowledge that any such action is in fact contemplated by the Commission or
the NASD.  The Company shall have advised the Underwriter of any NASD
affiliation of any of its officers or directors.
    

               (h)  The estimated revenues and earnings of the Company for the
six months ending September 30, 1996 will be greater than those of the six
months ended September 30, 1995.

               (i)  If any of the conditions herein provided for in this Section
shall not have been fulfilled as of the date indicated, this Agreement and all
obligations of the Underwriter under this Agreement may be cancelled at, or at
any time prior to, each Closing Date by the Underwriter.  Any such cancellation
shall be without liability of the Underwriter to the Company.

          5.   CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.  The obligation of
the Company to sell and deliver the Units is subject to the following
conditions:

               (a)  The Registration Statement shall have become effective not
later than 10:00 A.M. New York time, on the day following the date of this
Agreement, or on such later date as the Company and the Underwriter may agree in
writing.

               (b)  At the Closing Dates, no stop orders suspending the
effectiveness of the Registration Statement shall have been issued under the Act
or any proceedings therefor initiated or threatened by the Commission.

               (c)  No action shall have been taken by the Commission or the
NASD the effect of which would make it improper, at any time prior to the
Closing Date, for members of the NASD to execute transactions (as principal or
agent) in the Units, Common Stock or the 


                                      -25-

<PAGE>

Warrants and no proceedings for the taking of such action shall have been
instituted or shall be pending, or, to the knowledge of the Underwriter or the
Company, shall be contemplated by the Commission or the NASD.  Each of the
Company and the Underwriter represents that at the date hereof it has no
knowledge that any such action is in fact contemplated by the Commission or
NASD.

          If the conditions to the obligations of the Company provided for in
this Section have been fulfilled on the First Closing Date but are not fulfilled
after the First Closing Date and prior to the Option Closing Date, then only the
obligation of the Company to sell and deliver the Units on exercise of the
option provided for in Section 2(b) hereof shall be affected.

          6.   INDEMNIFICATION.

               (a)  The Company agrees to indemnify and hold harmless the
Underwriter and each person, if any, who controls the Underwriter within the
meaning of the Act against any losses, claims, damages or liabilities, joint or
several (which shall, for all purposes of this Agreement, include, but not be
limited to, all reasonable costs of defense and investigation and all attorneys'
fees), to which the Underwriter or such controlling person may become subject,
under the Act or otherwise, and will reimburse, as incurred, such Underwriter
and such controlling persons for any legal or other expenses reasonably incurred
in connection with investigating, defending against or appearing as a third
party witness in connection with any losses, claims, damages or liabilities,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in (A) the Registration Statement, any
Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto,
(B) any blue sky application or other document executed by the Company
specifically for that purpose or based upon written information furnished by the
Company filed in any state or other jurisdiction in order to qualify any or all
of the Units under the securities laws thereof (any such application, document
or information being hereinafter called a "Blue Sky Application"), or arise out
of or are based upon the omission or alleged omission to state in the
Registration Statement, any Preliminary Prospectus, Prospectus, or any amendment
or supplement thereto, or in any Blue Sky Application, a material fact required
to be stated therein or necessary to make the statements therein not misleading;
provided, however, that the Company will not be liable in any such case to the
extent, but only to the extent, that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in reliance upon and in conformity with
written information furnished to the Company by or on behalf of the Underwriter
specifically for use in the preparation of the Registration Statement or any
such amendment or supplement thereof or any such Blue Sky Application or any
such preliminary Prospectus or the Prospectus or any such amendment or
supplement thereto.  This indemnity will be in addition to any liability which
the Company may otherwise have.


                                      -26-

<PAGE>

   
               (b)  The Underwriter will indemnify and hold harmless the
Company, each of its directors, each nominee (if any) for director named in the
Prospectus, each of its officers who have signed the Registration Statement, and
each person, if any, who controls the Company within the meaning of the Act,
against any losses, claims, damages or liabilities (which shall, for all
purposes of this Agreement, include, but not be limited to, all costs of defense
and investigation and all attorneys' fees) to which the Company or any such
director, nominee, officer or controlling person may become subject under the
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in the Registration
Statement, any Preliminary Prospectus, the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or the
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in the Registration
Statement, any Preliminary Prospectus, the Prospectus, or any amendment or
supplement thereto (i) in reliance upon and in conformity with written
information furnished to the Company by you specifically for use in the
preparation thereof and (ii) relates to the transactions effected by the
Underwriter in connection with the offer and sale of the Units contemplated
hereby.  This indemnity agreement will be in addition to any liability which the
Underwriter may otherwise have.
    

               (c)  Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section, notify in writing the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Section.  In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate in, and, to the extent that
it may wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, subject to the provisions herein stated, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party under this Section for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation.  The indemnified party
shall have the right to employ separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the indemnifying party if the indemnifying party
has assumed the defense of the action with counsel reasonably satisfactory to
the indemnified party; provided that if the indemnified party is an Underwriter
or a person who controls such Underwriter within the meaning of the Act, the
fees and expenses of such counsel shall be at the expense of the indemnifying
party if (i) the employment of such counsel has been specifically authorized in
writing by the indemnifying party or (ii) the named parties to any such action
(including any impleaded parties) include both such Underwriter or 


                                      -27-

<PAGE>

   
such controlling person and the indemnifying party, and the indemnified party 
shall have reasonably concluded that there may be one or more legal defenses 
available to it which are different from or additional to those available to 
the indemnifying party and that as a result, representation of both parties 
by the same counsel would be inappropriate due to actual or potential 
differing interests between them (in which case the indemnifying party shall not
have the right to assume the defense of such action on behalf of such
Underwriter or such controlling person, it being understood, however, that the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys for the
Underwriter and controlling persons, which firm shall be designated in writing
by you).  No settlement of any action against an indemnified party shall be made
without the consent of the indemnifying party, which shall not be unreasonably
withheld in light of all factors of importance to such indemnifying party.
    

          7.   CONTRIBUTION.

          In order to provide for just and equitable contribution under the Act
in any case in which (i) the Underwriter makes claim for indemnification
pursuant to Section 6 hereof but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case, notwithstanding the fact that
the express provisions of Section 6 provide for indemnification in such case, or
(ii) contribution under the Act may be required on the part of the Underwriter,
then the Company and each person who controls the Company, in the aggregate, and
the Underwriter shall contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (which shall, for all purposes of this
Agreement, include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees) in either such case (after
contribution from others) in such proportions that the Underwriter is
responsible in the aggregate for that portion of such losses, claims, damages or
liabilities represented by the percentage that the underwriting discount per
Unit appearing on the cover page of the Prospectus bears to the public offering
price appearing thereon, and the Company shall be responsible for the remaining
portion, provided, however, that (a) if such allocation is not permitted by
applicable law then the relative fault of the Company and the Underwriter and
controlling persons, in the aggregate, in connection with the statements or
omissions which resulted in such damages and other relevant equitable
considerations shall also be considered.  The relative fault shall be determined
by reference to, among other things, whether in the case of an untrue statement
of a material fact or the omission to state a material fact, such statement or
omission relates to information supplied by the Company, or the Underwriter and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such untrue statement or omission.  The Company and the
Underwriter agree that it would not be just and equitable if the respective
obligations of the Company and the Underwriter to contribute pursuant to this
Section 7 were to be determined by pro rata or per capita allocation of the
aggregate damages or by any other method of allocation that does not take
account of the equitable considerations referred to in the first sentence of
this Section 7.  No person guilty of a fraudulent misrepresentation (within the
meaning of 


                                      -28-

<PAGE>

Section 11(f) of the Act) shall be entitled to contribution from any person who
is not guilty of such fraudulent misrepresentation.  As used in this paragraph,
the word "Company" includes any officer, director, or person who controls the
Company within the meaning of Section 15 of the Act.  If the full amount of the
contribution specified in this paragraph is not permitted by law, then the
Underwriter and each person who controls the Underwriter shall be entitled to
contribution from the Company, its officers, directors and controlling persons
to the full extent permitted by law.  The foregoing contribution agreement shall
in no way affect the contribution liabilities of any persons having liability
under Section 11 of the Act other than the Company and the Underwriter.  No
contribution shall be requested with regard to the settlement of any matter from
any party who did not consent to the settlement; provided, however, that such
consent shall not be unreasonably withheld in light of all factors of importance
to such party.

          8.   COSTS AND EXPENSES.

   
               (a)  Whether or not this Agreement becomes effective or the 
sale of the Units to the Underwriter is consummated, the Company will pay all 
costs and expenses incident to the performance of this Agreement by the 
Company including, but not limited to, the fees and expenses of counsel to 
the Company and of the Company's accountants; the costs and expenses incident 
to the preparation, printing, filing and distribution under the Act of the 
Registration Statement (including the financial statements therein and all 
amendments and exhibits thereto), Preliminary Prospectus and the Prospectus, 
as amended or supplemented, or the Term Sheet, the fee of the NASD in 
connection with the filing required by the NASD relating to the offering of 
the Units contemplated hereby; all expenses, including reasonable fees and 
disbursements of counsel to the Underwriter, in connection with the 
qualification of the Units under the state securities or blue sky laws which 
the Underwriter shall designate; the cost of printing and furnishing to the 
Underwriter copies of the Registration Statement, each Preliminary 
Prospectus, the Prospectus, this Agreement, Selling Agreement, Underwriter's 
Questionnaire, and the Blue Sky Memorandum, any fees relating to the listing 
of the Common Stock and Warrants on the Nasdaq National Market or any other 
securities exchange, the cost of printing the certificates representing the 
securities comprising the Units, the fees of the transfer agent and warrant 
agent the cost of publication of at least three "tombstones" of the offering 
(at least one of which shall be in national business newspaper and one of 
which shall be in a major New York newspaper) and the cost of preparing at 
least four hard cover "bound volumes" relating to the offering, in accordance 
with the Underwriter's request.  The Company shall pay any and all taxes 
(including any transfer, franchise, capital stock or other tax imposed by any 
jurisdiction) on sales to the Underwriter hereunder.  The Company will also 
pay all costs and expenses incident to the furnishing of any amended 
Prospectus or of any supplement to be attached to the Prospectus as called 
for in Section 3(a) of this Agreement except as otherwise set forth in said 
Section.
    

               (b)  In addition to the foregoing expenses the Company shall at
the First Closing Date pay to D.H. Blair Investment Banking Corp., a
non-accountable expense 


                                      -29-

<PAGE>

allowance of $330,000 of which $30,000 has been paid.  In the event the
overallotment option is exercised, the Company shall pay to D.H. Blair
Investment Banking Corp. at the Option Closing Date an additional amount equal
to 3% of the gross proceeds received upon exercise of the overallotment option. 
In the event the transactions contemplated hereby are not consummated by reason
of any action by the Underwriter (except if such prevention is based upon a
breach by the Company of any covenant, representation or warranty contained
herein or because any other condition to the Underwriter's obligations hereunder
required to be fulfilled by the Company is not fulfilled) the Company shall not
be liable for the accountable expenses of the Underwriter, however, the
Underwriter may in all events retain the aforementioned $30,000 advance on the
non-accountable expense allowance.  In the event the transactions contemplated
hereby are not consummated by reason of any action of the Company or because of
a breach by the Company of any covenant, representation or warranty herein, the
Company shall be liable for the accountable expenses of the Underwriter,
including legal fees, up to a maximum of $330,000.

               (c)  No person is entitled either directly or indirectly to
compensation from the Company, from the Underwriter or from any other person for
services as a finder in connection with the proposed offering, and the Company
agrees to indemnify and hold harmless the Underwriter, against any losses,
claims, damages or liabilities, joint or several (which shall, for all purposes
of this Agreement, include, but not be limited to, all costs of defense and
investigation and all attorneys' fees), to which the Underwriter or person may
become subject insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon the claim of any
person (other than an employee of the party claiming indemnity) or entity that
he or it is entitled to a finder's fee in connection with the proposed offering
by reason of such person's or entity's influence or prior contact with the
indemnifying party.

          9.   EFFECTIVE DATE.

          The Agreement shall become effective upon its execution except that
you may, at your option, delay its effectiveness until 11:00 A.M., New York time
on the first full business day following the effective date of the Registration
Statement, or at such earlier time after the effective date of the Registration
Statement as you in your discretion shall first commence the initial public
offering by the Underwriter of any of the Units.  The time of the initial public
offering shall mean the time of release by you of the first newspaper
advertisement with respect to the Units, or the time when the Units are first
generally offered by you to dealers by letter or telegram, whichever shall first
occur.  This Agreement may be terminated by you at any time before it becomes
effective as provided above, except that Sections 3(c), 6, 7, 8, 12, 13, 14 and
15 shall remain in effect notwithstanding such termination.

          10.  TERMINATION.

               (a)  This Agreement, except for Sections 3(c), 6, 7, 8, 12, 13,

and the option referred to 


                                      -30-

<PAGE>

   
in Section 2(b) hereof, if exercised, may be cancelled at any time prior to the
Option Closing Date, by you if in your judgment it is impracticable to offer for
sale or to enforce contracts made by the Underwriter for the resale of the Units
agreed to be purchased hereunder by reason of (i) the Company having sustained a
material loss, whether or not insured, by reason of fire, earthquake, flood,
accident or other calamity, or from any labor dispute or court or government
action, order or decree; (ii) trading in securities on the New York Stock
Exchange, the American Stock Exchange, the Nasdaq SmallCap Market or the Nasdaq
National Market having been suspended or limited; (iii) material governmental
restrictions having been imposed on trading in securities generally (not in
force and effect on the date hereof); (iv) a banking moratorium having been
declared by federal or New York state authorities; (v) an outbreak of
international hostilities or other national or international calamity or crisis
or change in economic or political conditions having occurred; (vi) a pending or
threatened legal or governmental proceeding or action relating generally to the
Company's business, or a notification having been received by the Company of the
threat of any such proceeding or action, which could materially adversely affect
the Company; (vii) except as contemplated by the Prospectus, the Company is
merged or consolidated into or acquired by another company or group or there
exists a binding legal commitment for the foregoing or any other material change
of ownership or control occurs; (viii) the passage by the Congress of the United
States or by any state legislative body or federal or state agency or other
authority of any act, rule or regulation, measure, or the adoption of any
orders, rules or regulations by any governmental body or any authoritative
accounting institute or board, or any governmental executive, which is
reasonably believed likely by the Underwriter to have a material impact on
the business, financial condition or financial statements of the Company or the
market for the securities offered pursuant to the Prospectus; (ix) any adverse
change in the financial or securities markets beyond normal market fluctuations
having occurred since the date of this Agreement, or (x) any material adverse
change having occurred, since the respective dates of which information is given
in the Registration Statement and Prospectus, in the earnings, business
prospects or general condition of the Company, financial or otherwise, whether
or not arising in the ordinary course of business.
    

               (b)  If you elect to prevent this Agreement from becoming
effective or to terminate this Agreement as provided in this Section 10 or in
Section 9, the Company shall be promptly notified by you, by telephone or
telegram, confirmed by letter.

          11.  UNIT PURCHASE OPTION.

   
          At or before the First Closing Date, the Company will sell to 
D.H. Blair Investment Banking Corp. (for its own account) or its designees 
for a consideration of $110, and upon the terms and conditions set forth in 
the form of Unit Purchase Option annexed as an exhibit to the Registration 
Statement, a Unit Purchase Option (the "Unit Purchase Option") to purchase an 
aggregate of 1,100 Units.  In the event of conflict in the terms of this 
Agreement and the Unit Purchase Option, the language of the Unit Purchase 
Option shall control.

          12.  REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.

          The respective indemnities, agreements, representations, warranties
and other statements of the Company or its Principal Stockholders, where
appropriate, and the undertakings set forth in or made pursuant to this
Agreement will remain in full force and effect, regardless of any investigation
made by or on behalf of the Underwriter, the Company or any of its officers or
directors or any controlling person and will survive delivery of and payment of
the Units and the termination of this Agreement.

          13.  NOTICE.

                         AMENDMENT TO WARRANT AGREEMENT

   
     AMENDMENT dated as of October 15, 1996 to the Warrant Agreement dated as 
of November 30, 1994 ("WARRANT AGREEMENT") by and among PREMIER LASER 
SYSTEMS, INC., a California corporation ("COMPANY"), AMERICAN STOCK TRANSFER

INVESTMENT BANKING CORP., a New York corporation ("BLAIR").  All terms used 
in this Amendment, unless otherwise defined herein, shall have such meaning 
as ascribed to them in the Warrant Agreement.
    
   
     WHEREAS, in connection with (i) a public offering ("SECONDARY OFFERING") 
of up to 12,650 units ("UNITS"), each unit consisting of  190 shares of Class 
A Common Stock and 95 redeemable Class B Warrants ("CLASS B WARRANTS") 
pursuant to an underwriting agreement (the "SECONDARY UNDERWRITING 
AGREEMENT") dated October 15, 1996 between the Company and Blair and (ii) the 
issuance to Blair or its designees of Unit Purchase Options to purchase an 
aggregate of 1,000 additional Units, to be dated as of October 18, 1996 (the

1,306,250 Class B Warrants; and
    
     WHEREAS, in connection with the Secondary Offering, the parties hereto
desire to amend certain provisions of the Warrant Agreement as set forth in this
Agreement in accordance with the provisions of Section 16 of the Warrant
Agreement;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
hereinafter set forth, the parties intending to be legally bound, hereby agree
as follows:

     A.   AMENDMENTS TO WARRANT AGREEMENT.  Upon the effective date of the
registration statement relating to the Secondary Offering, the Warrant Agreement
shall be amended as follows:
   
     (1)  The number of Class B Warrants subject to issuance under the 
Warrant Agreement is hereby increased to 9,033,448 Class B Warrants.
    
     (2)  Subsection (d) of Section 1 of the Warrant Agreement shall be deleted
in its entirety and replaced with the following new subsection (d):

          "(d) "Initial Warrant Exercise Date" shall mean as to each Class
     A Warrant and Class B    Warrant the date of issuance of such Class A
     Warrant or Class B Warrant, as the case may be."

     (3)  Subsections (e), (f) and (g) of Section 2 of the Warrant Agreement
shall be deleted in their entirety and replaced with the following new
subsections (e), (f) and (g):


<PAGE>

   
          "(e)  From time to time, up to the Warrant Expiration Date, the
     Transfer Agent shall countersign and deliver stock certificates in
     required whole number denominations representing up to an aggregate of
     13,439,547 shares of Class A Common Stock, subject to adjustment as
     described herein, upon the exercise of Warrants in accordance with
     this Agreement.
    
          (f)  From time to time, up to the Warrant Expiration Date, the
     Warrant Agent shall countersign and deliver Warrant Certificates in
     required whole number denominations to the persons entitled thereto in
     connection with any transfer or exchange permitted under this
     Agreement; provided that no Warrant Certificates shall be issued
     except:  (i) those initially issued hereunder; (ii) those issued on or
     after the Initial Warrant Exercise Date, upon the exercise of fewer
     than all Warrants represented by any Warrant Certificate, to evidence
     any unexercised Warrants held by the exercising Registered Holder;
     (iii) those issued upon any transfer or exchange pursuant to Section
     6; (iv) those issued in replacement of lost, stolen, destroyed or
     mutilated Warrant Certificates pursuant to Section 7; (v) those issued
     pursuant to the Unit Purchase Options and the Secondary Unit Purchase
     Options; (vi) at the option of the Company, in such form as may be
     approved by its Board of Directors, to reflect any adjustment or
     change in the Purchase Price, the number of shares of Class A Common
     Stock purchasable upon exercise of the Warrants or the Target Price(s)
     therefor made pursuant to Section 8 hereof; and (vii) those Class B
     Warrants issued upon exercise of Class A Warrants.
   
          (g)  Pursuant to the terms of the Unit Purchase Options and the
     Secondary Unit Purchase Options, Blair or its designees may purchase
     Units, which include up to 240,000 Class A Warrants and 584,500
     Class B Warrants.  Notwithstanding anything to the contrary contained
     herein, the Warrants underlying the Unit Purchase Options and the
     Secondary Unit Purchase Options shall not be subject to redemption by
     the Company except under the terms and conditions set forth in the
     Unit Purchase Options and Secondary Unit Purchase Options, as the case
     may be."
    
   
     (4)  Subsection (b) of Section 4 of the Warrant Agreement shall be 
deleted in its entirety and replaced with the following new subsection (b):

          "(b) If, at the Exercise Date, in respect of the exercise of any 
     Warrants (i) the market price of the Company's Class A Common Stock is 
     greater than the then Purchase Price of the Warrant, (ii) the exercise 
     of the Warrant was solicited by a member of the National Association of 
     Securities Dealers, Inc. ("NASD") as designated in writing on the 
     Warrant Certificate Subscription Form, (iii) the Warrant was not held in 
     a discretionary account, (iv) disclosure of compensation arrangements 
     was made both at the time of the original offering and at the time of 
     exercise; and (v) the solicitation of the exercise of the Warrant was 
     not in violation of Rule 10b-6 (as such rule or any successor rule may 
     be in effect as of such time of exercise) promulgated under the 
     Securities Exchange Act of 1934, then the Warrant Agent, simultaneously 
     with the distribution of the Warrant Proceeds to the Company shall, on 
     behalf of the Company, pay from the Warrant Proceeds, a fee of 5% (the 
     "Blair Fee") of the Purchase Price to Blair (of which a portion may be 
     reallowed by Blair to the dealer who solicited the exercise, which may 
     also be Blair or D.H. Blair & Co., Inc.); PROVIDED, HOWEVER, in the 
     event any Warrants are exercised but prior to October 15, 1997, Blair 
     shall only be entitled to receive the Blair Fee with respect to the 
     3,845,000 Class A Warrants and 6,605,000 Class B Warrants (which include 
     the 3,845,000 Class B Warrants that may be issued on exercise of the 
     Class A Warrants) issued at the time of the Company's initial public 
     offering in November 1994. For purposes of determining which Warrants 
     have been exercised, it will be assumed that the first 5,885,000 Class B 
     Warrants exercised were those issued at the time of the Company's 
     initial public offering. In the event the Blair Fee is not received 
     within five days of the date on which the Company receives Warrant 
     Proceeds, then the Blair Fee shall begin accruing interest at an annual 
     rate of prime plus four (4)%, payable by the Company to Blair at the 
     time Blair receives the Blair Fee. Within five days after exercise the 
     Warrant Agent shall send to Blair a copy of the reverse side of each 
     Warrant exercised. Blair shall reimburse the Warrant Agent, upon 
     request, for its reasonable expenses relating to compliance with this 
     section 4(b). In addition, Blair and the Company may at any time during 
     business hours, examine the records of the Warrant Agent, including its 
     ledger of original Warrant Certificates returned to the Warrant Agent 
     upon exercise of Warrants. The provisions of this paragraph may not be 
     modified, amended or deleted without the prior written consent of Blair 
     and the Company."
    
   
     (5)  The first paragraph of subsection (a) of Section 9 of the Warrant
Agreement shall be deleted in its entirety and replaced with the following new
paragraph:
    
          "(a) Subject to the exceptions referred to in Section 9(g) below,
     in the event the Company shall, at any time or from time to time after
     the date hereof, sell any shares of Common Stock for a consideration
     per share less than the Market Price of the Class A Common Stock


                                       -2-

<PAGE>


     (as defined in Section 8, except that for purposes of Section 9, the
     Calculation Date shall mean the date of the sale or other transaction
     referred to in this Section 9) on the date of the sale or issue any shares
     of Common Stock as a stock dividend to the holders of Common Stock, or
     subdivide or combine the outstanding shares of Common Stock into a greater
     or lesser number of shares (any such sale, issuance, subdivision or
     combination being herein called a "Change of Shares"), then, and thereafter
     upon each further Change of Shares, the Purchase Price in effect
     immediately prior to such Change of Shares shall be changed to a price
     (including any applicable fraction of a cent) determined by multiplying the
     Purchase Price in effect immediately prior thereto by a fraction, the
     numerator of which shall be the sum of the number of shares of Common Stock
     outstanding immediately prior to the issuance of such additional shares and
     the number of shares of Class A Common Stock which the aggregate
     consideration received (determined as provided in subsection 9(f)(F) below)
     for the issuance of such additional shares would purchase at the Market
     Price and the denominator of which shall be the sum of the number of shares
     of Common Stock outstanding immediately after the issuance of such
     additional shares.  Such adjustment shall be made successively whenever
     such an issuance is made."

     (5)  The reference in subsection (d) of Section 9 to "Section 2(d)" shall
be replaced with the reference to "Section 2(f)".

     (6)  Section 20 of the Warrant Agreement shall be deleted in its entirety
and replaced with the following new Section 20:

          "SECTION 20.  TERMINATION.  This Agreement shall terminate at the
     close of business on the earlier of the Warrant Expiration Date or the
     date upon which all Warrants (including the Warrants issuable upon
     exercise of the Unit Purchase Options and the Secondary Unit Purchase
     Options) have been exercised, except that the Warrant Agent shall
     account to the Company for cash held by it and the provisions of
     Section 15 hereof shall survive such termination."

     B.   FULL FORCE AND EFFECT.  Except as provided herein, all other terms and
provisions of the Warrant Agreement shall remain in full force and effect.

     C.   COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, which taken together shall constitute a single document.


                                       -3-

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed as of the date first above written.
