(1)     Consists of (i) 6,500,000  shares issuable upon conversion of $7,000,000
        principal  amount of  Convertible  Debentures  with  interest at varying
        rates of 6%, 7% and 8% due September 30, 2002 (the  "Debentures");  (ii)
        413,109  shares  issued  in  connection  with the  Debentures  and (iii)
        4,000,000  shares  held  by a  third-party  lender  as  security  for  a

        terms  described in the Selling  Stockholders  and Plan of  Distribution
        sections of the Prospectus.

(2)     Estimated  solely for  purposes of  calculation  of the fee.  The actual
        number of  shares  of  common  stock  issuable  upon  conversion  of the
        Debentures  may be more or less than such estimate based on a variety of
        factors,  including the date of  conversion  and the price of the common
        stock on such date.  The fee is estimated  pursuant to Rule 457(c) under
        the Act on the  basis of the  average  of the  high and low sale  prices
        reported on the Nasdaq SmallCap Market on December 10, 1997.

        Pursuant to Rule 416, there are also  registered  hereby such additional
indeterminate  number of shares of such Common  Stock as may become  issuable as
dividends or to prevent dilution resulting from stock splits, stock dividends or
similar transactions or as the result of floating rate conversion  mechanisms as
set forth in the terms of the Debentures referred to above.

        The registrant hereby amends this Registration Statement on such date or
dates as may be necessary to delay its effective date until the registrant shall
file a further  amendment  which  specifically  states  that  this  Registration
Statement shall  thereafter  become effective in accordance with Section 8(a) of
the Securities  Act of 1933 or until this  Registration  Statement  shall become
effective on such date as the Commission,  acting pursuant to said Section 8(a),
may determine.

                                                     the  laser  services  segment,  which is in the  developmental

                                                     prevent  dilution,  in  accordance  with  Rule 416  under  the

                                  RISK FACTORS

AN INVESTMENT IN THE SHARES  OFFERED  HEREBY  INVOLVES A HIGH DEGREE OF RISK AND
SHOULD  NOT BE MADE BY  PERSONS  WHO  CANNOT  AFFORD  THE LOSS OF  THEIR  ENTIRE
INVESTMENT.  IN  CONNECTION  WITH THE "SAFE  HARBOR"  PROVISIONS  OF THE PRIVATE
SECURITIES  LITIGATION  REFORM ACT OF 1995,  THE  COMPANY IS HEREBY  IDENTIFYING
IMPORTANT  FACTORS  THAT  COULD  CAUSE THE  COMPANY'S  ACTUAL  RESULTS TO DIFFER
MATERIALLY  FROM THOSE  PROJECTED IN  FORWARD-LOOKING  STATEMENTS OF THE COMPANY
MADE BY OR ON BEHALF OF THE COMPANY.  THE COMPANY  ADVISES  READERS NOT TO PLACE
UNDUE RELIANCE ON SUCH  FORWARD-LOOKING  STATEMENTS,  WHICH SPEAK ONLY AS OF THE
DATE HEREOF,  IN LIGHT OF THE RISKS AND UNCERTAINTIES TO WHICH THEY ARE SUBJECT.
THE COMPANY  UNDERTAKES  NO  OBLIGATION  TO RELEASE  PUBLICLY  THE RESULT OF ANY
REVISIONS TO THESE FORWARD-LOOKING STATEMENTS THAT MAY BE MADE TO REFLECT EVENTS
OR  CIRCUMSTANCES  AFTER  THE  DATE  HEREOF  OR TO  REFLECT  THE  OCCURRENCE  OF
UNANTICIPATED  EVENTS.  THE FOLLOWING FACTORS SHOULD BE CONSIDERED  CAREFULLY IN
EVALUATING THE COMPANY AND ITS BUSINESS.

        SUBSTANTIAL AND CONTINUING  LOSSES.  The Company  incurred a net loss of
$37,863,792  for the year ended December 31, 1996, a net loss of $36,989,569 for
the quarter ended  September 30, 1997 and a net loss of $67,167,702 for the nine
months  ended  September  30,  1997.  Losses of this  magnitude  are expected to
continue for the near term,  and there can be no assurance that the Company will
achieve profitable operations or that profitable operations will be sustained if
achieved.  The Company's  accumulated  deficit was  $64,971,200  at December 31,
1996,  and   $133,366,880   at  September  30,  1997.   Each  of  the  Company's
subsidiaries, Dynaco Corp. ("Dynaco"), Star Medical Technologies, Inc. ("Star"),
Tissue  Technologies,  Inc.  ("Tissue"),  Spectrum  Medical  Technologies,  Inc.
("Spectrum"),  Palomar Medical Products,  Inc. ("PMP"),  Cosmetic  Technologies,
Inc. ("CTI") and Nexar Technologies, Inc. ("Nexar") has had a history of losses.
There  can  be  no  assurance  that  these  companies  will  achieve  profitable
operations  or that  profitable  operations  will be sustained if achieved.  The
Company anticipates  incurring  substantial  research and development  expenses,
which will reduce cash  available to fund current  operations.  The Company must
continue to secure additional financing to complete its research and development
activities,  commercialize  its current and proposed cosmetic laser products and
fund  ongoing   operations.   The  Company  anticipates  that  it  will  require
substantial  additional  financing during the immediate  foreseeable future. The
Company's  strategic  plan is to  liquidate  certain  assets  to fund  its  core
operations over the next twelve-month period. However, there can be no assurance
that the Company will be able to execute this strategy,  due to market and legal
factors  outside its control,  among other things.  Additionally,  to the extent
that the  Company  incurs  indebtedness  to fund  increased  levels of  accounts
receivable  or to finance the  acquisition  of capital  equipment or issues debt
securities in connection  with any  acquisition,  the Company will be subject to
risks associated with incurring substantial additional  indebtedness,  including
the risks that interest rates may fluctuate and cash flow may be insufficient to
pay principal and interest on any such  indebtedness.  The Company  continues to
investigate several financing  alternatives,  including strategic  partnerships,
additional  bank financing,  liquidation of assets,  and private debt and equity
financing,  among other sources.  While the Company  regularly reviews potential
funding sources, there can be no assurance that the current levels of funding or
additional  funding  will be  available,  or,  if  available,  will be on  terms
satisfactory to the Company. Failure to obtain additional financing could have a
material  adverse  effect on the  Company,  including  possibly  requiring it to
significantly  curtail its  operations.  (See December 31, 1996 Form  10-KSB/A-4
"Item 1. Description of Business," Note 1 to Financial Statements,  and "Item 6.
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations";  and  September  30,  1997 Form  10-Q Part I "Item 2.  Management's
Discussion and Analysis of Financial Condition and Results of Operations.")

        COHERENT  AGREEMENT.  The  Company  has  entered  into a  Sales  Agency,
Development and License Agreement (the "Coherent Agreement") with Coherent, Inc.
("Coherent")  under which  Coherent  will act as exclusive  distributor  for the
Company's  laser based hair removal  systems in the United States,  Far East and
most European  countries.  As a result,  the Company no longer has its own sales
force in these  countries.  If Coherent  proves  unable to sell  Palomar's  hair
removal  lasers in the volume  anticipated,  it could  have a  material  adverse
effect on the Company's business, financial condition and results of operations.

        NEXAR.  As of November  18,  1997,  the  Company  owns 58% of the voting
capital stock of Nexar. In order to successfully  execute its business plan, the
Company is to a certain  degree  dependent  on the  success of Nexar and Nexar's
ability to fund its operations and achieve  profitability  in the near term. The
Company may reduce its  ownership of Nexar over time as it continues to focus on
its core cosmetic laser  business.  (See  "Substantial  and Continuing  Losses;"
"Highly Competitive Industries;" "Government Regulation;" "Uncertainty of Market
Acceptance;"   "Technological   Obsolescence;"   "Lack  of  Patent  Protection;"
"Dependence on Sole Suppliers;" and "Dependence on Substantial Customers.")

                                       7
<PAGE>

        RISKS   ASSOCIATED  WITH  PENDING   LITIGATION.   The  Company  and  its
subsidiaries  are involved in disputes  with third  parties.  Such disputes have
resulted  in  litigation  with such  parties  and,  although  the  Company  is a
plaintiff in several matters, the Company is subject to claims and counterclaims
for damages and has incurred,  and likely will continue to incur, legal expenses
in connection with such matters.  There can be no assurance that such litigation
will result in  favorable  outcomes  for the  Company.  The Company is unable to
determine  the total expense or possible  loss,  if any, that may  ultimately be
incurred in the  resolution  of these  proceedings.  These matters may result in
diversion of  management  time and effort from the  operations  of the business.
After  consideration of the nature of the claims and the facts relating to these
proceedings,  the Company believes that the resolution of these proceedings will
not have a material effect on the Company's  business,  financial  condition and
results of operations; however, the results of these proceedings,  including any
potential  settlements,  are  uncertain  and there can be no  assurance  to that
effect. (See September 20, 1997 Form 10-Q, Part II "Item 1. Legal Proceedings.")

        HOLDING  COMPANY  STRUCTURE.  The Company has no significant  operations
other  than  those  incidental  to its  ownership  of the  capital  stock of its
subsidiaries.  As a holding  company,  the Company is  dependent on dividends or
other  intercompany  transfers  of  funds  from  its  subsidiaries  to meet  the
Company's  debt  service  and  other  obligations.  Claims of  creditors  of the
Company's subsidiaries,  including trade creditors, will generally have priority
as to the assets of such  subsidiaries  over the claims of the  Company  and the
holders of the Company's indebtedness.

        FUTURE OPERATING  STRATEGY.  The Company's future operating strategy and
results  are  dependent  on its  ability to  successfully  divest  its  non-core
subsidiaries  and  successfully  execute its business plan in the cosmetic laser
products and  services  businesses.  There can be no assurance  that the Company
will be able to successfully execute this plan.

        LIMITED OPERATING HISTORY;  RECENT  ACQUISITIONS.  Many of the Company's
subsidiaries have limited operating  histories and are in the development stage,
and the Company is subject to all of the risks inherent in the  establishment of
a new  business  enterprise.  The  likelihood  of success of the Company must be
considered in light of the problems, expenses,  difficulties,  complications and
delays  frequently  encountered in connection  with the  establishment  of a new
business and development of new  technologies in the cosmetic laser products and
electronic  products  industries.   These  include,  but  are  not  limited  to,
government   regulation,   competition,   the  need  to   expand   manufacturing
capabilities  and  market  expertise,   and  setbacks  in  production,   product
development,  market acceptance and sales and marketing. The Company's prospects
could be  significantly  affected  by its  ability  to  subsequently  manage and
integrate the operations of several distinct  businesses with diverse  products,
services and customer bases in order to achieve cost efficiencies. (See December
31,  1996  Form  10-KSB/A-4  "Item 1.  Description  of  Business"  and Note 1 to
Financial Statements.)

        NEW  VENTURES.  The Company's  CTI  subsidiary  has entered into several
agreements  with  healthcare  providers,   including  Columbia/HCA,  to  provide
cosmetic laser services at laser treatment centers, and plans to enter into more
such agreements in the future. While the Company believes these new partnerships
are strategically important, there are substantial uncertainties associated with
the development of new products, technologies and services for evolving markets.
The  success of these  ventures  will be  determined  not only by the  Company's
efforts,  but  also  by  those  of its  partners.  Initial  timetables  for  the
development and introduction of new  technologies,  products or services may not
be achieved,  and  price/performance  targets may not prove  feasible.  External
factors,  such as the  development  of  competitive  alternatives  or government
regulation,  may cause new markets to evolve in unanticipated  directions.  (See
"Highly Competitive  Industries," and December 31, 1996 Form 10-KSB/A-4 "Item 1.
Description of Business.")

        INVESTMENTS  IN UNRELATED  BUSINESSES.  The Company has  investments  in
marketable  and  non-marketable  securities  and loans to related and  unrelated
parties,  including  approximately $3 million  invested in equity  securities of
high-tech companies, both public and privately held. The amount that the Company
may ultimately  realize from these  investments could differ materially from the
value of these investments recorded in the Company's financial  statements,  and
the  ultimate  disposition  of these  investments  could result in a loss to the
Company.  During the third quarter, the Company established reserves for certain
operating  assets  and  liabilities  that  resulted  in a charge to  expense  of
approximately  $9,426,000.  Included in the reserves,  the Company  recognized a
restructuring  charge of $2,700,000  based on the decision to  discontinue  some
business units and  consolidate  others.  The Company also assessed its non-core
long-term assets and investments and determined that some investments'  carrying
value  will not be  realizable  due to the  Company's  change in  strategy.  The
Company has fully reserved for all such investments  resulting in a charge to to
third quarter operations of approximately  $13,548,000.  (See September 30, 1997
Form  10-Q  Note 2 to  Financial  Statements  and Part I "Item  2.  Management's
Discussion and Analysis of Financial Condition and Results of Operations.")

                                       8

        HIGHLY  COMPETITIVE  INDUSTRIES.  The cosmetic  laser industry is highly
competitive and is characterized  by the frequent  introduction of new products.
The Company competes in the development,  manufacturing, marketing and servicing
of  laser  products  with  numerous  other  companies,  certain  of  which  have
substantially greater financial, marketing and other resources than the Company.
In addition,  the  Company's  cosmetic  laser  products  face  competition  from
alternative medical products and procedures,  such as pharmaceutical  treatment,
electrolysis,  waxing and surgery,  among others. There can be no assurance that
the Company will be able to differentiate  its products from the products of its
competitors or that the marketplace  will consider the Company's  products to be
superior to competing products or medical procedures.  There can be no assurance
that competitors will not develop products or that new technologies  will not be
developed that render the Company's products obsolete or less competitive.  (See
"Technological  Obsolescence.")  In addition,  in entering  areas of business in
which it has little or no  experience,  such as the  opening of laser  treatment
centers,  the Company may not be able to compete  successfully  with competitors
that are more established in such areas. (See "New Ventures.")

        The Company's Nexar subsidiary competes with IBM, Apple Computer, Compaq
and Dell  Computer,  among others.  Many,  if not most,  of Nexar's  current and
prospective  competitors are substantial in size and have substantial financial,
managerial,  technical,  manufacturing,  marketing and other resources,  and may
introduce  additional products that compete with those of Nexar. There can be no
assurance that Nexar's products will compete  favorably with the products of its
competitors  or  that  Nexar  will  have  the  resources  necessary  to  compete
effectively  against such companies.  As a result of the intense  competition in
the personal computer market, the Company expects that gross margins on sales of
Nexar's upgradeable personal computers will be extremely narrow and will require
Nexar to manage carefully its cost of goods sold. There can be no assurance that
Nexar will be able to manage its cost of goods sold to the degree  necessary for
sales of upgradeable  computer  products to generate  significant gross margins.
Nexar  currently  has  limited  marketing  capabilities  and  expects  to  place
significant   reliance  on  independent   distributors  and  resellers  for  the
distribution  and  marketing of its products.  Nexar will be dependent  upon the
efforts of such third parties. The inability to establish and maintain a network
of  independent  distributors  and  resellers,  or a  reduction  in their  sales
efforts, could have a material adverse effect on Nexar's financial condition and
results  of  operations.  In  addition,  there  can  be no  assurance  as to the
viability or financial stability of independent  distributors and resellers. The
computer  industry  has  been  characterized  from  time to  time  by  financial
difficulties  of  distributors  and  resellers;  any such problems could lead to
reduced  sales  and  could  have a  material  adverse  effect  on the  Company's
financial  condition and results of  operations.  There can be no assurance that
Nexar's products will compete  favorably with the products of its competitors or
that the  Company  will have the  resources  necessary  to  compete  effectively
against  such  companies.  (See  December  31,  1996  Form  10-KSB/A-4  "Item 1.
Description of Business.")

        FLUCTUATIONS  IN  QUARTERLY   PERFORMANCE.   The  Company's  results  of
operations have fluctuated substantially and can be expected to continue to vary
significantly.  The Company's  quarterly operating results depend on a number of
factors,  including the timing of the introduction or acceptance of new products
offered by the Company or its  competitors,  changes in the mix of products sold
by the Company,  changes in regulations affecting the cosmetic laser products or
electronics  industry,  changes in the Company's operating  expenses,  personnel
changes and general economic conditions.

        VOLATILITY OF SHARE PRICE. Factors such as announcements of developments
related to the  Company's  business,  announcements  by  competitors,  quarterly
fluctuations in the Company's  financial results,  changes in analysts' earnings
estimates,  market conditions in the high technology  sector, as well as general
economic  conditions  and other  factors have caused the price of the  Company's
stock to fluctuate, in some cases substantially,  and could continue to do so in
the future.  In addition,  the stock market has  experienced  extreme  price and
volume  fluctuations that have  particularly  affected the market price for many
technology  companies  and that  have  often  been  unrelated  to the  operating
performance of these  companies.  These broad market  fluctuations may adversely
affect the market price of the Company's common stock.

                                       9

        GOVERNMENT  REGULATION.  The Company's laser product business segment is
subject to regulation  in the United  States and abroad.  Failure to comply with
applicable regulatory  requirements can result in fines, denial or suspension of
approvals,  seizures or recall of products,  operating restrictions and criminal
prosecutions,  any or all of which could have a material  adverse  effect on the
Company.  Furthermore,  changes  in  existing  regulations  or  adoption  of new
regulations could prevent the Company from obtaining, or could affect the timing
of, future regulatory approvals. (See December 31, 1996 Form 10-KSB/A-4 "Item 1.
Description of Business - Government Regulation.")

        All laser  product  devices,  including  those sold by the Company,  are
subject to  regulation  by the FDA under the Medical  Device  Amendments  of the
United States Food, Drug and Cosmetics Act (the "FDA Act"). The Company's future
operating  results are dependent on its ability to develop,  produce and achieve
FDA approval for certain medical products and market new and innovative products
and  services.  There are  numerous  risks  inherent  in this  complex  process,
including rapid technological  change and the requirement that the Company bring
to market in a timely  fashion new products and services  which meet  customers'
changing needs.

        FDA CLEARANCE STATUS FOR COSMETIC LASER PRODUCTS. Three of the Company's
lasers  have  received  clearance  from  the  FDA  for  certain   dermatological
applications:  the  Q-switched  Ruby laser,  the TruPulse laser and the EpiLaser
laser system.  The Company's  StarLite(TM)  diode hair-removal laser has not yet
received  FDA  clearance,   and  is  currently  under  an  Investigative  Device
Exemption.

        The Company is also investigating  other applications in dermatology for
its  laser  systems.  It  will  be  required  to  obtain  FDA  clearance  before
commercially marketing any other application.  The Company believes that it will
be able to seek such clearance under the 510(k) application process; however, no
assurance  can be given that the FDA will not  require the Company to follow the
more extensive and  time-consuming  Pre-Market  Approval  ("PMA")  process.  FDA
review of a 510(k)  application  currently averages about seven to twelve months
and requires  limited  clinical  data based on  "substantial  equivalence"  to a
product  marketed  prior to 1976,  while a PMA review can last for several years
and require substantially more clinical data.

        The FDA also imposes various  requirements on manufacturers  and sellers
of  products  under  its  jurisdiction,  such as  labeling,  good  manufacturing
practices,  record keeping and reporting requirements.  The FDA also may require
post-market  testing and surveillance  programs to monitor a product's  effects.
There can be no assurance that the  appropriate  clearances from the FDA will be
granted,  that the process to obtain  such  clearances  will not be  excessively
expensive  or lengthy or that the Company will have  sufficient  funds to pursue
such clearances.

        No  assurance  can be given that FDA  approval  will be obtained for the
Company's  current or proposed laser products on a timely basis,  if at all. The
laser  products  segment of the Company's  business is, and will continue to be,
critically  dependent  upon FDA  approval of its current and  proposed  cosmetic
laser products.  Delays or failure to obtain such approval would have a material
adverse effect on the Company.

        OTHER  GOVERNMENT  APPROVALS  FOR  LASER  PRODUCTS;  GOOD  MANUFACTURING
PRACTICES. In order to be sold outside the United States, the Company's products
are subject to FDA permit  requirements  that are conditioned  upon clearance by
the importing country's appropriate regulatory authorities.  Many countries also
require that imported products comply with their own or international electrical
and safety standards.  Additional  approvals may be required in other countries.
The Company's TruPulse laser and EpiLaser laser system have received the CE Mark
pursuant to the European  Medical Device Directive which allows that laser to be
sold in all countries that  recognize the CE Mark,  including the countries that
comprise the European Community.  The Company has yet to apply for international
approval for its diode laser for use in cosmetic surgery and dermatology.

        The Company is subject to the laser radiation safety  regulations of the
FDA Act administered by the National Center for Devices and Radiological  Health
("CDRH") of the FDA. These regulations  require a laser manufacturer to file new
product and annual reports,  to maintain  quality  control,  product testing and
sales  records,  to distribute  appropriate  operation  manuals,  to incorporate
certain design and operating features in lasers sold to end-users and to certify
and label each laser sold to end-users  as one of four classes of lasers  (based
on the level of radiation from the laser).  In addition,  various warning labels
must be affixed on the product and certain  protective devices must be installed
depending upon the class of product. Under the Act, the Company is also required
to  register  with the FDA as a medical  device  manufacturer  and is subject to
inspection on a routine basis by the FDA for compliance with Good  Manufacturing
Practice ("GMP") regulations.  The GMP regulations impose certain procedural and
documentation  requirements  upon the  Company  relevant  to its  manufacturing,
testing and quality control activities.  The CDRH is empowered to seek fines and
other remedies for violations of these regulatory requirements.

                                       10
<PAGE>

        UNCERTAINTY OF MARKET ACCEPTANCE. The Company is developing new products
intended  for use in the  cosmetic  laser  products  segment.  As  with  any new
products,  there is substantial  risk that the  marketplace may not accept or be
receptive to the potential  benefits of such products.  Market acceptance of the
Company's  current and proposed  products will depend,  in large part,  upon the
ability  of  the  Company  or  any  marketing  partners  to  demonstrate  to the
marketplace  the  advantages  of the  Company's  products  over  other  types of
products.  There can be no assurance that applications or uses for the Company's
current and proposed products will be accepted by the marketplace or that any of
the Company's current or proposed products will be able to compete  effectively.
(See December 31, 1996 Form 10-KSB/A-4 "Item 1. Description of Business.")

        DEPENDENCE  ON THIRD PARTY  RESEARCHERS.  The  Company is  substantially
dependent upon third party  researchers and others,  over which the Company will
not have absolute control,  to  satisfactorily  conduct and complete research on
behalf of the Company and to grant to the Company favorable  licensing terms for
products  which may be  developed.  The  Company  has  entered  into a number of
research   agreements   with   recognized   research   hospitals   and  clinical
laboratories.  These  research  institutions  include the Oregon  Medical  Laser
Center at the Heart  Institute of St.  Vincent  Hospital  and Medical  Center in
Portland,  Oregon,  the Wellman Labs at  Massachusetts  General Hospital and the
Otolaryngology  Research  Center for  Advanced  Endoscopic  Applications  at New
England Medical Center,  Boston,  Massachusetts.  The Company provides  research
funding, laser technology and optics know-how in return for licensing agreements
with respect to specific medical  applications and patents.  Management believes
that this method of conducting research and development  provides a higher level
of technical  and clinical  expertise  than it could provide on its own and in a
more cost efficient manner.  The Company's success will be highly dependent upon
the results of the research,  and there can be no assurance  that these research
agreements  will provide the Company with  marketable  products in the future or
that any of the products developed under these agreements will be profitable for
the Company.  (See December 31, 1996 Form  10-KSB/A-4  "Item 1.  Description  of
Business" and Note 6 to Financial Statements.)

        TECHNOLOGICAL  OBSOLESCENCE.  The markets for the Company's products are
characterized by rapid and significant  technological change,  evolving industry
standards and frequent new product  introductions and enhancements.  Many of the
Company's   products  and  products  under   development   are   technologically
innovative, and require significant planning, design, development and testing at
the technological,  product and manufacturing  process levels.  These activities
require  significant  capital  commitments  and  investment by the Company.  The
Company's  failure to develop products in a timely manner in response to changes
in the industry,  whether for financial,  technological  or other reasons,  will
have a material adverse effect on the Company's  business,  financial  condition
and results of  operations.  (See  December  31, 1996 Form  10-KSB/A-4  "Item 1.
Description of Business.")

       NEED FOR CONTINUED  PRODUCT  DEVELOPMENT.  Although the Company received
FDA clearance in March 1997 to commercially market its EpiLaser(TM) laser system
for hair  removal,  the  Company is  continuing  to study  this laser  system to
optimize performance and treatment parameters.

        LACK OF PATENT  PROTECTION.  The Company currently holds several patents
and intends to pursue various  additional  avenues that it deems  appropriate to
protect its  technology.  There can be no assurance,  however,  that the Company
will file any additional  patent  applications  or that any patent  applications
that have been,  or may be,  filed will  result in issued  patents,  or that any
patent, patent application,  know-how,  license or cross-license will afford any
protection or benefit to the Company.

        The cosmetic laser device market has been  characterized  by substantial
litigation  regarding patent and other intellectual  property rights. One of the
Company's  competitors in the cosmetic laser business has filed suit against the
Company alleging patent  infringement,  among other things. In both the cosmetic
laser products and the electronic  products  segments,  litigation,  which could
result in  substantial  cost to and  diversion of effort by the Company,  may be
necessary  to protect  trade  secrets or  know-how  owned by or  licensed to the
Company  or  to  determine  the  enforceability,   scope  and  validity  of  the
proprietary   rights  of  others.   Adverse   determination   in  litigation  or
interference proceedings could subject the Company to significant liabilities to
third parties, require the Company to seek licenses from third parties and could
prevent the Company from  manufacturing  and selling its products,  all of which
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations. (See September 30, 1997 10-Q, Part II "Item
1. Legal Proceedings.")

        POSSIBLE PATENT  INFRINGEMENTS.  In the medical  products  segment,  the
Company  is aware of  patents  relating  to laser  technologies  used in certain
applications.  The  Company  intends to pursue  such laser  technologies  in the
future;  hence,  if the  patents  relating to those  technologies  are valid and
enforceable, they may be infringed by the Company. After consulting with outside

                                       11
<PAGE>

counsel to the Company, the Company believes that it is not infringing currently
on patents held by others; however, were the issue ever to be litigated, a court
could  reach a  different  conclusion.  If the  Company's  current  or  proposed
products  are,  in the  opinion of patent  counsel,  infringing  on any of these
patents, the Company intends to seek non-exclusive,  royalty-bearing licenses to
such  patents  but  there can be no  assurance  that any such  license  would be
available on favorable terms, if at all. One of the Company's competitors in the
cosmetic  laser  business  has filed suit  against the Company  alleging  patent
infringement,  among other  things.  In the  electronic  products  segment,  the
Company has not been notified that it is currently infringing on any patents nor
has it been the subject of any patent  infringement  action. No assurance can be
given  that  infringement  claims  will  not be made or that the  Company  would
prevail  in any  legal  action  with  respect  thereto.  Defense  of a claim  of
infringement  would be costly and could have a  material  adverse  effect on the
Company's business, even if the Company were to prevail. (See September 30, 1997
10-Q, Part II "Item 1. Legal Proceedings.")

        DEPENDENCE ON  PROPRIETARY  RIGHTS.  The Company relies on trade secrets
and proprietary  know-how which it seeks to protect, in part, by confidentiality
agreements with its  collaborators,  employees and consultants.  There can be no
assurance  that these  agreements  will not be breached,  that the Company would
have adequate  remedies for any breach, or that the Company's trade secrets will
not otherwise become known or be independently developed by competitors.

        NEED FOR QUALIFIED  PERSONNEL/DEPENDENCE ON KEY PERSONNEL. The Company's
ability to develop,  manufacture and market all of its products, and to attain a
competitive position within the laser products and electronics industries,  will
depend, in large part, on its ability to attract and retain qualified personnel.
Competition  for  qualified  personnel  in these  industries  is intense and the
Company will be required to compete for such personnel with companies  which may
have greater  financial and other resources;  there can be no assurance that the
Company  will be  successful  in  attracting,  assimilating  and  retaining  the
personnel it requires to grow and operate profitably. The Company's inability to
attract and retain such personnel could have a material  adverse effect upon its
business, financial condition and results of operations.

        The Company's  future  success  depends to a  significant  extent on its
executive  officers and certain technical,  managerial and marketing  personnel.
The loss of the  services of any of these  individuals  or group of  individuals
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

        ISSUANCE OF PREFERRED STOCK AND DEBENTURES COULD AFFECT RIGHTS OF COMMON
SHAREHOLDERS.  The  Company  is  authorized  to issue up to 5 million  shares of
Preferred  Stock,  $.01 par value.  The Preferred  Stock may be issued in one or
more series, the terms of which may be determined at the time of issuance by the
Board of Directors,  without  further  action by  shareholders,  and may include
voting rights  (including the right to vote as a series on particular  matters),
preferences as to dividends and  liquidation,  conversion and redemption  rights
and sinking fund  provisions.  In July 1996,  the Company issued 6,000 shares of
Series F  Convertible  Preferred  Stock  at a price  of  $1,000  per  share.  In
September  1996,  the  Company  issued  10,000  shares of  Series G  Convertible
Preferred Stock at a price of $1,000 per share.  As of November 30, 1997,  7,316
shares of Series G Preferred  Stock were converted into 602,824 shares of common
stock and 956,388 shares of Nexar common stock and $47,731 in cash dividends. In
March 1997,  the Company  issued 6,000 shares of Series H Convertible  Preferred
Stock at a price of  $1,000  per  share.  In May  1997,  the  Company  issued an
additional  10,000 shares of Series H Convertible  Preferred Stock at a price of
$1,000 per share.  As of November 30,  1997,  7,690 shares of Series H Preferred
Stock were converted into  4,504,008  shares of common stock.  In July 1996, the
Company  issued  9,675 units in a  convertible  debenture  financing.  Each unit
consisted  of a  convertible  debenture  denominated  in 1,000 Swiss francs (the
"Swiss franc  Debentures")  and a warrant to purchase 24 shares of the Company's
common stock at $16.50 per share.  In February  1997, 300 units were redeemed by
the Company for an aggregate price of $195,044.  As of November 13, 1997, acting
under applicable  provisions of the indenture,  the Company notified the holders
of the Swiss franc  Debentures  that it is causing the  conversion of all of the
Swiss franc  Debentures  into an  aggregate of 914,024  shares of the  Company's
common stock.  These shares have not been accounted for in shares outstanding as
the  Debentures  are still  outstanding.  The Company is involved in  litigation
regarding  certain  provisions of the  indenture.  (See  September 30, 1997 Form
10-Q, Part II "Item 1. Legal  Proceedings.") In October 1996, the Company issued
$5,000,000 in 4.5% Convertible Subordinated Promissory Notes. As of November 30,
1997,  $4,900,000 principal amount was converted into 1,381,264 shares of common
stock.  In  December  1996  and  January  1997,  the  Company  issued a total of
$6,000,000 in 5% Convertible Debentures. As of November 30, 1997, $3,911,716 was
converted  into  1,919,992  shares of common stock.  In March 1997,  the Company
issued  $5,500,000  in 5%  Convertible  Debentures.  As of  November  30,  1997,
$3,773,666 was converted into 2,250,266  shares of common stock.  In March 1997,
the Company issued $500,000 in 6% Convertible Debentures. In September 1997, the

                                       12
<PAGE>

Company  issued a total of $7,000,000 in 6%, 7% and 8%  Convertible  Debentures.
The issuance of any such additional  Preferred Stock or Debentures  could affect
the rights of the holders of Shares,  and could  reduce the market  price of the
Shares.  In particular,  specific  rights granted to future holders of Preferred
Stock or  Debentures  could be used to restrict the  Company's  ability to merge
with or sell its  assets to a third  party,  thereby  preserving  control of the
Company by the existing  control group.  (See December 31, 1996 Form  10-KSB/A-4
"Item 1. Description of Business," "Item 5. Market for Common Equity and Related
Stockholder  Matters," and Notes 4 and 5 to Financial  Statements  and September
30, 1997 Form 10-Q, Notes 7 and 8 to Financial  Statements and Part II, "Item 2.
Changes in Securities.")

        ISSUANCE OF RESERVED  SHARES;  REGISTRATION  RIGHTS.  As of November 30,
1997, the Company had 43,116,141 shares of common stock outstanding. The Company
has  reserved an  additional  34,505,015  shares for  issuance  as follows:  (1)
3,709,504 shares for issuance to key employees, officers, directors, consultants
and advisors  pursuant to the Company's  Stock Option Plans;  (2) 212,690 shares
for issuance to  employees,  officers and  directors  pursuant to the  Company's
401(k) Plan; (3) 984,623 shares for issuance pursuant to the Company's  Employee
Stock Purchase Plan; (4) 9,412,940  shares for issuance upon exercise of three-,
four-  five- and  seven-year  Warrants  issued to  certain  lenders,  investors,
consultants,  directors  and officers (a portion of which are subject to certain
antidilutive  adjustments);  (5) 600,000 shares for issuance upon  conversion of
the 6,000 shares of Series F Convertible Preferred Stock; (6) 487,176 shares for
issuance upon  conversion of the 2,684 shares of Series G Convertible  Preferred
Stock;  (7) 7,690,760 shares for issuance upon conversion of the 8,310 shares of
Series H  Convertible  Preferred  Stock (8)  1,275,000  shares for issuance upon
conversion  of the Swiss franc  Debentures;  (9) 65,393 shares for issuance upon
conversion  of  $100,000  principal  amount of a 4.5%  Convertible  Subordinated
Promissory   Note;  (10)  1,899,889  shares  for  issuance  upon  conversion  of
$2,088,284 principal amount of a 5% Convertible Debenture; (11) 1,621,585 shares
for issuance upon conversion of $1,726,334  principal amount of a 5% Convertible
Debenture; (12) 45,455 shares for issuance upon conversion of $500,000 principal
amount of a 6% Convertible Debenture and (13) 6,500,000 shares for issuance upon
conversion  of  $7,000,000  principal  amount  of a 6%,  7% and  8%  Convertible
Debenture.  All of the foregoing reserved shares are, or the Company intends for
them shortly to be, registered with the Commission and therefore freely saleable
on Nasdaq or elsewhere.

        PRODUCT  LIABILITY  EXPOSURE.  Cosmetic laser product  companies face an
inherent business risk of financial  exposure to product liability claims in the
event that the use of their products results in personal  injury.  The Company's
products are and will continue to be designed with numerous safety features, but
it is possible  that patients  could be adversely  affected by use of one of the
Company's  products.  Further,  in the event that any of the Company's  products
prove to be  defective,  the Company may be required to recall and redesign such
products.  Although the Company has not  experienced  any material losses due to
product  liability  claims to date,  there can be no assurance  that it will not
experience such losses in the future.  The Company  maintains  general liability
insurance in the amount of  $1,000,000  per  occurrence  and  $2,000,000  in the
aggregate  and  maintains   umbrella   coverage  in  the  aggregate   amount  of
$25,000,000; however, there can be no assurance that such coverage will continue
to be available on terms acceptable to the Company or that such coverage will be
adequate for liabilities  actually  incurred.  In the event the Company is found
liable for damages in excess of the limits of its insurance coverage,  or if any
claim or product  recall results in significant  adverse  publicity  against the
Company,  the Company's business,  financial condition and results of operations
could be materially and adversely affected. In addition,  although the Company's
products have been and will continue to be designed to operate in a safe manner,
and although the Company  attempts to educate medical  personnel with respect to
the proper use of its  products,  misuse of the  Company's  products  by medical
personnel over whom the Company cannot exert control may result in the filing of
product liability claims or significant adverse publicity against the Company.

        DEPENDENCE ON SOLE  SUPPLIERS.  The Company relies on outside  suppliers
for  substantially  all of its  manufacturing  supplies,  parts and  components.

        Several  component  parts of the Company's  cosmetic  laser products are
manufactured  exclusively  by one supplier.  There can be no assurance  that the
Company  will be able to  obtain  a  sufficient  supply  of such  components  at
commercially  reasonable  prices or at all. A shortage  of  necessary  parts and
components or the  inability of the Company to obtain such parts and  components
would  have a  material  adverse  effect on the  Company's  business,  financial
condition  and results of  operations.  (See  December 31, 1996 Form  10-KSB/A-4
"Item 1. Description of Business.")

                                       13
<PAGE>

        In July 1997, one of Nexar's two outside turn-key manufacturers notified
Nexar of its  inability to timely  manufacture  on a going forward basis Nexar's
proprietary motherboards.  Nexar made arrangements with two new manufacturers to
assume timely  production of the  motherboards.  Nexar does not believe that the
transition  to the new  manufacturers  will have a  long-term  material  adverse
effect on Nexar,  but the  several  weeks it took to resume full  production  of
these key  components  had a short-term  negative  impact on Nexar's  results of
operations in the third quarter due to limited  delays in the initial  shipments
of Nexar's new XPA  products,  and could  similarly  impact  Nexar's  results of
operations in the fourth quarter.

        DEPENDENCE  ON  SUBSTANTIAL  CUSTOMERS.  In the year ended  December 31,
1996, one customer of Nexar,  Government  Technology  Services,  Inc. ("GTSI), a
leading  supplier  of desktop  systems  to United  States  government  agencies,
accounted  for  17.5% of the  Company's  revenues  and  23.2%  of the  Company's
accounts  receivable  balance.  In the quarter ended  September  30, 1997,  GTSI
accounted for 3.3% of the Company's revenues and 17.1% of the Company's accounts
receivable  balance.  The  Company  expects  that  GTSI will  continue  to be an
important  customer,  and that,  while Nexar's revenues from GTSI will increase,
such sales as a percentage of total revenue will decline  substantially as Nexar
further expands its distribution  network and increases its overall sales. Nexar
has entered into an agreement with GTSI pursuant to which GTSI serves as Nexar's
exclusive  federal reseller with respect to Government  Services  Administration
(GSA) scheduled purchases,  provided that GTSI purchases at least $35 million of
Nexar's products in 1997. GTSI is under no obligation,  however, to purchase any
products  of Nexar.  If GTSI  makes  fewer  purchases  in 1997 than the  Company
anticipates, that would have a material adverse effect on the Company.

        UNCERTAINTY  OF  HEALTHCARE  REIMBURSEMENT  AND REFORM.  The  healthcare
industry is subject to changing  political,  economic and regulatory  influences
that may affect the procurement  practices and operations of healthcare industry
participants.  During  the past  several  years,  state and  federal  government
regulation of reimbursement rates and capital  expenditures in the United States
healthcare  industry has increased.  Lawmakers  continue to propose  programs to
reform the United  States  healthcare  system,  which may  contain  programs  to
increase  governmental  involvement in  healthcare,  lower Medicare and Medicaid
reimbursement  rates or  otherwise  change  the  operating  environment  for the
Company's  customers.  Healthcare  industry  participants  may  react  to  these
proposals by curtailing or deferring  investments,  including investments in the
Company's products.

        HAZARDOUS  SUBSTANCE AND ENVIRONMENTAL  CONCERNS;  LACK OF ENVIRONMENTAL
IMPAIRMENT  INSURANCE.   The  manufacture  of  substrate  interconnect  products
involves  numerous  chemical  solvents and other solid,  chemical and  hazardous
wastes and materials. The Company's Dynaco subsidiary is subject to a variety of
environmental laws relating to the generation, storage, handling, use, emission,
discharge and disposal of these substances and potentially  significant risks of
statutory and common law liability for environmental damage and personal injury.
The  Company,  and  in  certain  circumstances,   its  officers,  directors  and
employees,  may be subject to claims  arising from the  Company's  manufacturing
activities,  including the improper release,  spillage, misuse or mishandling of
hazardous or non-hazardous  substances or material.  The Company may be strictly
liable for damages,  regardless  of whether it  exercised  due care and complied
with all relevant laws and regulations.  The Company does not currently maintain
environmental  impairment insurance.  There can be no assurance that the Company
will not face claims resulting in substantial liability for which the Company is
uninsured  or that  hazardous  substances  are not or will not be present at the
Company's  facilities.   The  Company  believes  that  it  operates  its  Dynaco
facilities  in  substantial  compliance  with  existing  environmental  laws and
regulations. In June 1989 and April 1994, Dynaco conducted environmental studies
of its Tempe, Arizona substrate  manufacturing facility and did not discover any
contamination  requiring  remediation.  Failure to comply with proper  hazardous
substance handling procedures or violation of environmental laws and regulations
would have a material adverse effect on the Company. (See December 31, 1996 Form
10-KSB/A-4 "Item 1. Description of Business.")

        SIGNIFICANT OUTSTANDING INDEBTEDNESS;  SUBORDINATION OF DEBENTURES.  The
Company has incurred substantial  indebtedness in relation to its equity capital
and will be subject to all of the risks  associated with  substantial  leverage,
including  the risk that  available  cash may not be adequate  to make  required
payments to the holders of the Company's  debentures.  The Company's  ability to
satisfy its  obligations  under the debentures  from cash flow will be dependent
upon the Company's future performance and will be subject to financial, business
and other factors  affecting the operation of the Company,  many of which may be
beyond the Company's control.  In the event the Company does not have sufficient
cash resources to satisfy quarterly  interest or other repayment  obligations to
the  holders  of the  debentures,  the  Company  will be in  default  under  the
debentures,  which would have a material  adverse effect on the Company.  To the
extent that the Company is required to use cash  resources  to satisfy  interest

                                       14
<PAGE>

payments to the holders of the debentures, it will have less resources available
for other  purposes.  Inability  of the  Company  to repay the  debentures  upon
maturity would have a material adverse effect on the Company, which could result
in a reduction of the price of the  Company's  Shares.  The  debentures  will be
unsecured and subordinate in right of payment to all senior  indebtedness of the
Company.  The  debentures  do  not  restrict  the  Company's  ability  to  incur
additional senior indebtedness and most other indebtedness.  The terms of senior
indebtedness  now existing or incurred in the future could affect the  Company's
ability  to make  payments  of  principal  and/or  interest  to the  holders  of
debentures.  (See December 31, 1996 Form  10-KSB/A-4  "Item 5. Market for Common
Equity and Related Shareholder  Matters";  September 30, 1997 Form 10-Q, Notes 7
and 8 to Financial  Statements and Part II "Item 1. Legal Proceedings;" "Item 2.
Changes in Securities.")

        POTENTIAL EFFECT OF ANTI-TAKEOVER PROVISIONS.  The Company is subject to
the anti-takeover  provisions of Section 203 of the Delaware General Corporation
Law, which prohibit the Company from engaging in a "business  combination"  with
an  "interested  stockholder"  for a period of three years after the date of the
transaction  in which the person becomes an interested  stockholder,  unless the
business  combination  is approved in a prescribed  manner.  The  application of
Section 203 could have the effect of delaying or  preventing a change of control
of the Company.  The  Company's  stock option  grants  generally  provide for an
exercise of some or all of the optioned stock, including non-vested shares, upon
a change of control or similar  event.  The Board of Directors  has authority to
issue  up to  5,000,000  shares  of  Preferred  Stock  and  to fix  the  rights,
preference,  privileges and  restrictions,  including  voting  rights,  of these
shares without any further vote or action by the stockholders. The rights of the
holders of the common  stock will be subject to, and may be  adversely  affected
by, the rights of the holders of any  Preferred  Stock that may be issued in the
future. The issuance of Preferred Stock, while providing  desirable  flexibility
in connection with possible  acquisitions  and other corporate  purposes,  could
have the  effect of  making it more  difficult  for a third  party to  acquire a
majority of the  outstanding  voting  stock of the  Company,  thereby  delaying,
deferring or  preventing a change in control of the Company.  Furthermore,  such
Preferred Stock may have other rights,  including  economic rights senior to the
common stock, and, as a result,  the issuance of such Preferred Stock could have
a  material  adverse  effect  on the  market  value of the  common  stock.  (See
"Issuance  of  Preferred  Stock and  Debentures  Could  Affect  Rights of Common
Shareholders.")

        RISKS ASSOCIATED WITH ACQUISITIONS.  Since going public, the Company has
acquired seven companies. Although the Company intends to focus primarily on its
laser based hair  removal  business  going  forward,  the  Company  nevertheless
evaluates potential  acquisitions of businesses,  products and technologies that
would  complement  or  expand  its core  business.  Promising  acquisitions  are
difficult  to  identify  and  complete  for  a  number  of  reasons,   including
competition  among  prospective  buyers and the need for  regulatory  approvals.
Acquisitions  may result in the incurrence of additional  debt, the write-off of
in-process  research and  development or technology  acquisition and development
costs and the  amortization of expenses related to goodwill and other intangible
assets,  any of which  could have a  material  adverse  effect on the  Company's
business, financial condition, results of operations and cash flow. Acquisitions
involve numerous additional risks, including difficulties in the assimilation of
the operations,  services,  products and personnel of the acquired company,  the
diversion of  management's  attention  from other  business  concerns,  entering
markets in which the Company has little or no direct  prior  experience  and the
potential  loss of key  employees of the acquired  company.  In order to finance
acquisitions,  it may be  necessary  for the Company to raise  additional  funds
through public or private financings. Any equity or debt financing, if available
at all, may be on terms which are not  favorable to the Company and, in the case
of equity financing, may result in dilution to the Company's stockholders.  (See
December 31, 1996 Form 10-KSB/A-4  "Item 1.  Description of Business" and Note 1
to Financial Statements.)

                                       15

                                   THE COMPANY

        The Company was  organized  to design,  manufacture  and market  lasers,
delivery systems and related disposable  products for use in medical procedures.
The  Company  currently  operates in three  business  segments:  cosmetic  laser
products,  cosmetic laser services,  and electronic products;  the Company is in
the process of divesting its non-core electronics subsidiaries.  In the cosmetic
laser products  segment,  the Company is focusing its efforts on the FDA-cleared
EpiLaser  hair removal laser and other hair removal  lasers are currently  under
development.  The Company  recently  entered into an agreement  with the world's
largest  laser  company,  Coherent,  pursuant  to  which  Coherent  will  act as
exclusive  distributor for the Company's laser hair removal systems in the U.S.,
Far East and most European countries.  Under this agreement,  Coherent also will
obtain a right  of first  refusal  to  distribute  the  Company's  future  laser
products, and Coherent and the Company have agreed to cross-license certain hair
removal technology. The Company anticipates that Coherent, with its direct sales
force numbering over 200, will be able to sell the Company's products in greater
volume  than the  Company  could  in the  past  through  its  independent  sales
representatives. However, the Company does not anticipate that its gross margins
will  improve  until  it  introduces  its new  ruby and  diode  cosmetic  lasers
currently under  development.  The Company is developing ruby and diode cosmetic
lasers for use in clinical trials and is engaged in the research and development
of additional cosmetic laser and surgical products.  (See December 31, 1996 Form
10-KSB/A-4  "Item 1.  Description  of  Business--Medical  Products and Lasers in
Medicine;  Future  Products.") The Company has entered into a number of research
agreements with recognized  research  hospitals and clinical  laboratories.  The
Company  provides  research  funding,  laser  technology and optics  know-how in
return for licensing  agreements to specific  cosmetic  laser  applications  and
patents.   Management  feels  that  this  method  of  conducting   research  and
development  provides a higher level of technical and clinical expertise than it
could provide on its own and in a more cost efficient manner.

        In late  1996,  CTI  was  formed  as a  wholly-owned  subsidiary  of the
Company.  CTI is a services  company  which  intends to  establish  a network of
cosmetic  dermatological  laser  sites with  medical  services  partners  in key
geographic  locations.  Each site will be  provided  a turnkey  package of laser
technology,  equipment,  training and service,  operations personnel,  strategic
advertising  and  marketing  programs,  patient  financial  credit  programs and
management  assistance.  In early  1997,  CTI  entered  into an  agreement  with
Columbia/HCA  to  establish  revenue  sharing  sites  throughout  the country in
existing Columbia/HCA  facilities.  To date, CTI has established fourteen sites.
CTI does not yet derive revenue from its operations.

        In  February  1997,  Palomar  Medical  Products,  Inc.  was  formed as a
wholly-owned  subsidiary  with the purpose of  consolidating  the management and
operations of the medical products companies.  Currently included in the medical
products group are the following  companies,  all of which are also wholly-owned
subsidiaries of the Company:  Spectrum,  Tissue,  Star, and Dermascan,  Inc. The
Company  plans  further  consolidation  in this  business,  as well, by focusing
principally on its laser hair removal technology. As part of this consolidation,
the  Company has entered  into a  non-binding  letter of intent with the current
management of Tissue to sell to them Tissue.

        In  September  1995,  the  Company   established   Palomar   Electronics
Corporation ("PEC"), a wholly-owned subsidiary,  as part of its plan to separate
the  electronics  segment  from the  cosmetics  segment.  On April 9,  Nexar,  a
subsidiary  of PEC,  completed an initial  public  offering of its common stock.
Nexar sold 2,500,000 shares of its common stock for its own account at $9.00 per
share and received net proceeds of approximately $20,300,000.  (See December 31,
1996 Form 10-KSB/A-4 "Item 1. Description of Business.) In the second quarter of
1997,  the Company  sold all of the issued and  outstanding  common stock of its
former  subsidiary  CD Titles.  The  Company  has signed an  agreement  with the
current  management of Dynaco to sell to them Dynaco and its  subsidiaries  in a
two phase transaction;  the first phase begins with the immediate sale of Comtel
and Dynamem  and, in the second  phase,  Dynaco will be sold by June 30, 1998 at
the latest.  The overall sale price for both phases is approximately ten million
dollars in notes,  common stock and warrants,  payable over time. As part of its
divestiture  strategy,  the Company will also consider winding down unprofitable
subsidiaries if doing so provides greater economic  benefits to the Company than
a sale.

        In  the  past,  the  Company  made  early  stage   investments  in  core
technologies  and in  companies  that  management  felt  were  strategic  to the
Company's  business  or would yield a higher than  average  financial  return to
support  the  Company's  core  business.  Some of these  investments  were  with
companies  that  were  related  to some of the  directors  and  officers  of the
Company.  In the third quarter of 1997, the Company determined that the carrying
value of some of its  non-core  long-term  assets and  investments  would not be
realizable due to the change in the Company's strategy. Accordingly, the Company
fully reserved for all such investments,  resulting in a charge to third quarter
operations of approximately $13,548,000.  (See December 31, 1996 Form 10-KSB/A-4
"Management Discussion and Analysis-- Liquidity and Capital Resources" and "Item
12. Certain Relationships and Related Transactions.")

        The Company will  continue to develop,  acquire or license  technologies
that can be  integrated  into its current and proposed  products in the cosmetic
laser  business  segment.  The  Company  intends to address  very large  markets
incorporating  its core  technology with  proprietary  products and services and
structure its  operations to strive to be the low-cost  producer and provider of
these  products  and  services.  The  Company  intends  to  seek  agreements  or
arrangements with other medical products and high technology  companies in order
to acquire technical and financial assistance in the research and development of
such  products  and in the  extensive  experimentation  and testing  required to
obtain regulatory approvals in the United States and elsewhere.

The Company's  strategic  plan is to liquidate  certain  assets to fund its core
operations over the next twelve-month  period.  (See "Risk  Factors--Substantial
and Continuing Losses.")

                                 USE OF PROCEEDS

        The Company will receive no part of the proceeds from the sale of any of
the Shares by the Selling Stockholders.

                              SELLING STOCKHOLDERS

        The following  table sets forth  information  concerning  the beneficial
ownership of shares of common stock by the Selling  Stockholders  as of the date
of this  Prospectus  and the  number of such  shares  included  for sale in this
Prospectus assuming the sale of all Shares being offered by this Prospectus. The
number of shares included in the Registration Statement of which this Prospectus
is a part and  available for resale (i) is based,  in part,  upon an estimate of
the  number  of  shares  underlying  the  Debentures  utilizing  a  hypothetical
conversion  price of $1.08,  (ii) is subject to  adjustment  and (iii)  could be
materially  more or less than such estimated  amount  depending on factors which
cannot be predicted by the Company at this time,  including,  among others,  the
future market price of the Company's common stock. The use of such  hypothetical
prices is not  intended,  and should in no way be  construed,  to  constitute  a
prediction as to the future market price of the Company's  common stock.  To the
best of the  Company's  knowledge,  except  as stated  in this  Prospectus,  the
Selling  Stockholders  have not held  any  office  or  maintained  any  material
relationship  with the Company or any of its predecessors or affiliates over the
past three  years.  The  Selling  Stockholders  reserve  the right to reduce the
number of shares offered for sale or to otherwise  decline to sell any or all of
the Shares registered hereunder.

1.      Pursuant to the rules of the Commission, shares of common stock which an
        individual  or group has a right to acquire  within 60 days  pursuant to
        the  exercise  of  options,   warrants  or  certain   other   derivitive
        instruments  (including the Debentures) are deemed to be outstanding for
        the purpose of computing the ownership of such  individual or group.  In
        addition,  pursuant to the terms of the  Debentures as described  below,
        the conversion  rights of the holders are limited to the extent that the
        number of shares of common stock  thereby  issuable,  together  with the
        number  of  shares of common  stock  then  held by such  holder  and its
        affiliates (not including shares which have not been converted),  exceed
        4.9%  of the  then  outstanding  common  stock  for the  Debentures,  as
        determined in accordance with Section 13(d) of the Exchange Act.

2.      The  actual  number of shares set forth  represent  an  estimate  of the
        number  of  shares  of  common  stock  to  be  offered  by  the  Selling
        Stockholders;  the actual number of shares of common stock issuable upon
        conversion of the Debentures is indeterminate,  is subject to adjustment
        and  could  be  materially  less  or more  than  such  estimated  number
        depending  on a number  of  factors  which  cannot be  predicted  by the
        Company at this time,  including among other factors,  the future market
        price of the common  stock.  The actual number of shares of common stock
        offered hereby, and included in the Registration Statement of which this
        prospectus is a part, includes such additional shares of common stock as
        may be issued or issuable upon conversion of the Debentures by reason of
        the  floating  rate  conversion  price  mechanism  or  other  adjustment
        mechanisms  described  therein,  or by reason of any stock split,  stock
        dividend or similar transaction  involving the common stock, in order to
        prevent  dilution,  in accordance with Rule 416 under the Securities Act
        of 1933.

        (10) days preceding conversion. The Debentures accrue interest at 6% for

                              PLAN OF DISTRIBUTION

        The 10,913,109  shares being  registered  herein for sale by the Selling
Stockholders  consist of (i) 6,500,000  shares  issuable upon  conversion of the
Debentures  (ii) 413,109  shares issued in connection  with the  Debentures  and
(iii) 4,000,000  shares held as security by a third-party for a guarantee by the
Company.

        The  Selling  Stockholders  and  their  respective   pledgees,   donees,
transferees  and  other  successors  in  interest  may  sell  the  common  stock
registered  in  connection  with this  Offering on the Nasdaq  market  system or
otherwise.  There will be no charges or  commissions  paid to the Company by the
Selling  Stockholders in connection with the resale of shares offered hereby. It
is  anticipated  that  usual and  customary  brokerage  fees will be paid by the
Selling  Stockholders  upon sale of the Shares offered hereby.  The Company will
pay the other expenses of this  Offering.  Such sales may be made on one or more
exchanges or in the  over-the-counter  market,  or otherwise at fixed prices, at
prices and at terms then  prevailing  or at prices  related to the then  current
market price,  or in negotiated  transactions.  The Shares may be sold by one or
more of the following methods:  (a) a block trade in which the broker so engaged
will  attempt to sell the Shares as agent but may  position and resell a portion
of the block as principal to  facilitate  the  transaction;  (b)  purchases by a
broker or dealer  as  principal  and  resale  by such  broker or dealer  for its
account pursuant to this Prospectus;  (c) an exchange distribution in accordance
with the rules of Nasdaq;  (d) ordinary  brokerage  transactions and (e) used to
cover short sales. In effecting sales, brokers or dealers engaged by the Selling
Stockholders may arrange for other brokers or dealers to participate. Brokers or
dealers  will receive  commissions  or discounts  from Selling  Stockholders  in
amounts to be negotiated prior to the sale. The Selling Stockholders and brokers
or dealers  and any other  participating  brokers or dealers may be deemed to be
"underwriters"  within the meaning of the Securities Act in connection with such
sales. In addition,  any securities covered by this Prospectus which qualify for
sale  pursuant  to Rule 144 may be sold under Rule 144 rather  than  pursuant to
this Prospectus.

        The Company has agreed to  indemnify  the Selling  Stockholders  against
certain liabilities,  including certain liabilities under the Securities Act, or
to contribute  to payments  which the Selling  Stockholders  will be required to
make in respect thereof.

                                     EXPERTS

        The audited  financial  statements  incorporated  by  reference  in this
Prospectus  and  elsewhere in the  registration  statement  have been audited by
Arthur  Andersen  LLP,  independent  public  accountants,  as indicated in their
reports with respect thereto, and are included herein upon the authority of said
Firm as experts in giving said reports.

                                 LEGAL OPINIONS

        The validity of the shares of common stock offered hereby will be passed
upon for the Company by its General Counsel.

            DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR
                           SECURITIES ACT LIABILITIES

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

ITEM 15.          INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Delaware  General   Corporation  Law,  Section   102(b)(7),   enables  a
corporation in its original certificate of incorporation or an amendment thereto
validly  approved by  stockholders  to eliminate or limit personal  liability of
members of its Board of Directors for violations of a director's  fiduciary duty
of care. However,  the elimination or limitation shall not apply where there has
been a breach of the duty of loyalty,  failure to act in good faith, engaging in
intentional  misconduct  or  knowingly  violating  a law,  paying a dividend  or
approving a stock  repurchase  which was deemed illegal or obtaining an improper
personal  benefit.  The  Company's  Certificate  of  Incorporation  includes the
following language:

"To the maximum extent permitted by Section 102(b)(7) of the General Corporation
Laws of Delaware,  a director of this corporation shall not be personally liable
to the  corporation  or its  stockholders  for  monetary  damages  for breach of
fiduciary  duty as a director,  except for  liability  (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions  not in good faith or which  involve  intentional  misconduct  or a
knowing  violation  of law,  (iii)  under  Section 174 of the  Delaware  General
Corporation  Law, or (iv) for any transaction from which the director derived an
improper personal benefit."

        Section  145 of the  General  Corporation  Law of the State of  Delaware
generally  provides  that a corporation  may  indemnify  any director,  officer,
employee  or agent  against  expenses,  judgments,  fines  and  amounts  paid in
settlement in connection  with any action  against him by reason of his being or
having been such a  director,  officer,  employee or agent,  if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation  and, with respect to any criminal  action,  had no
reasonable cause to believe his conduct was unlawful.  No indemnification  shall
be made,  however,  if he is adjudged liable for negligence or misconduct in the
performance of his duty to the corporation, unless a court determines that he is
nevertheless  entitled to indemnification.  If he is successful on the merits or
otherwise in defending the action,  the  corporation  must indemnify him against
expenses  actually and reasonably  incurred by him.  Article IX of the Company's
Bylaws provides indemnification as follows:


                                       21
<PAGE>

INDEMNIFICATION

SECTION 1. Actions,  Etc. Other Than by or in the Right of the Corporation.  The
Corporation shall, to the full extent legally permissible,  indemnify any person
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative  or  investigative,  including a grand jury  proceeding,  and all
appeals (but excluding any such action, suit or proceeding by or in the right of
the  Corporation),  by reason of the fact that such person is or was a director,
executive  officer (as  hereinafter  defined) or advisory  council member of the
Corporation,  or is or was  serving  at the  request  of  the  Corporation  as a
director,  officer,  partner, trustee, employee or agent of another corporation,
partnership,   joint  venture,  trust  or  other  enterprise,  against  expenses
(including  attorneys'  fees),  judgments,  fines and amounts paid in settlement
actually and reasonably  incurred by such person in connection with such action,
suit or  proceeding  if such  person  acted in good  faith and in a manner  such
person reasonably  believed to be in or not opposed to the best interests of the
Corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable  cause  to  believe  the  conduct  in  question  was  unlawful.   The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction,  or upon a plea of nolo contendere or its equivalent,  shall not, of
itself, create a presumption that such person did not act in good faith and in a
manner which such person reasonably believed to be in or not opposed to the best
interests  of the  Corporation,  and,  with  respect to any  criminal  action or
proceeding, that such person had reasonable cause to believe that the conduct in
question was unlawful. As used in this Article IX, an "executive officer" of the
Corporation is the  president,  treasurer,  a vice president  given the title of
executive vice president,  or any officer designated as such pursuant to vote of
the Board of Directors.

SECTION 2. Actions. Etc. by or in the Right of the Corporation.  The Corporation
shall, to the full extent legally  permissible,  indemnify any person who was or
is a party or is  threatened  to be made a party to any  threatened,  pending or
completed  action  or  suit,  including  appeals,  by or in  the  right  of  the
Corporation to procure a judgment in its favor,  by reason of the fact that such
person is or was a director or executive  officer of the  Corporation as defined
in  Section  1 of this  Article,  or is or was  serving  at the  request  of the
Corporation  as a  director,  officer,  partner,  trustee,  employee or agent of
another  corporation,  partnership,  joint venture,  trust or other  enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection  with the defense or settlement of such action or suit
if such  person  acted in good  faith  and in a manner  such  person  reasonably
believed  to be in or not  opposed  to the best  interests  of the  corporation,
except that no  indemnification  shall be made in respect of any claim, issue or
matter as to which  such  person  shall have been  adjudged  to be liable to the
Corporation  unless and only to the  extent  that the Court of  Chancery  or the
court in which such action or suit was brought shall determine upon  application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

SECTION 3. Determination of Right of  Indemnification.  Any indemnification of a
director or officer (unless ordered by a court) shall be made by the Corporation
only  as  authorized  in the  specific  case  upon  a  determination  that  such
indemnification is proper in the circumstances because the director or executive
officer  has met the  applicable  standard of conduct as set forth in Sections 1
and 2 hereof.  Such a determination shall be reasonably and promptly made (i) by
the Board of Directors by a majority  vote of a quorum  consisting  of directors
who were not  parties to such  action,  suit or  proceeding,  or (ii) (if such a
quorum is not  obtainable,  or, even if obtainable if a quorum of  disinterested
directors so directs) by  independent  legal  counsel in a written  opinion,  or
(iii) by the stockholders.

SECTION 4. Indemnification Against Expenses of Successful Party. Notwithstanding
any other provision of this Article, to the extent that a director or officer of
the  Corporation  has  been  successful  in whole  or in part on the  merits  or
otherwise, including the dismissal of an action without prejudice, in defense of
any  action,  suit or  proceeding  or in defense  of any claim,  issue or matter
therein,  such person  shall be  indemnified  against all  expenses  incurred in
connection therewith.

SECTION 5. Advances of Expenses.  Expenses  incurred by a director or officer in
any action,  suit or proceeding  shall be paid by the  Corporation in advance of
the final  disposition of thereof,  if such person shall undertake to repay such
amount in the event that it is ultimately  determined,  as provided herein, that
such person is not entitled to  indemnification.  Notwithstanding the foregoing,
no advance shall be made by the Corporation if a determination is reasonably and
promptly  made (i) by the Board of Directors  by a majority  vote of a quorum of
disinterested directors, or (ii) (if such a quorum is not obtainable or, even if
obtainable,  if a quorum of  disinterested  directors so directs) by independent
legal  counsel in a written  opinion,  that,  based upon the facts  known to the


                                       22
<PAGE>

Board of Directors or such counsel at the time such  determination is made, such
person  has not met the  relevant  standards  set forth for  indemnification  in
Section 1 or 2, as the case may be.

SECTION  6.  Right  to   Indemnification   Upon   Application:   Procedure  Upon
Application.  Any indemnification or advance under Sections 1, 2, 4 or 5 of this
Article shall be made  promptly,  and in any event within ninety days,  upon the
written request of the person seeking to be indemnified,  unless a determination
is reasonably and promptly made by the Board of Directors that such person acted
in a manner set forth in such  Sections so as to justify the  Corporation's  not
indemnifying  such person or making  such an advance.  In the event no quorum of
disinterested  directors is  obtainable,  the Board of Directors  shall promptly
appoint  independent  legal  counsel to decide  whether the person  acted in the
manner  set  forth in such  Sections  so as to  justify  the  Corporation's  not
indemnifying such person or making such an advance. The right to indemnification
or advances as granted by this Article  shall be  enforceable  by such person in
any court of competent  jurisdiction,  if the Board of Directors or  independent
legal  counsel  denies  the  claim  therefor,  in  whole  or in  part,  or if no
disposition of such claim is made within ninety days.

SECTION 7. Other Right and Remedies: Continuation of Rights. The indemnification
and  advancement  of  expenses  provided  by this  Article  shall  not be deemed
exclusive of any other  rights to which any person  seeking  indemnification  or
advancement  of expenses  may be entitled  under any Bylaw,  agreement,  Vote of
stockholders  or  disinterested  directors,  the General  Corporation Law of the
State of  Delaware or  otherwise,  both as to action in such  person's  official
capacity and as to action in another  capacity  while  holding such office.  All
rights to  indemnification  or advancement under this Article shall be deemed to
be in the nature of  contractual  rights  bargained for and  enforceable by each
director  and  executive  officer as defined  in Section 1 of this  Article  who
serves in such  capacity  at any time  while  this  Article  and other  relevant
provisions  of the General  Corporation  Law of the State of Delaware  and other
applicable laws, if any, are in effect. All right to indemnification  under this

in part upon any such state of facts.  The Corporation  shall also indemnify any

vote  pertaining  to a specific  officer,  employee or agent,  advisory  council

director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other enterprise  against any liability asserted against such
person and incurred by such person in any such capacity,  or arising out of such
person's status as such,  whether or not the Corporation would have the power to
indemnify  such person  against  such  liability  under the  provisions  of this
Article.

directors and officers so that any person who is or was a director or officer of
such a  constituent  corporation  or is or was  serving  at the  request of such
constituent  corporation  as a  director  or  officer  of  another  corporation,
partnership,  joint venture,  trust or other  enterprise shall stand in the same
position  under the  provisions of this Article with respect to the resulting or
surviving corporation as such person would have with respect to such constituent
corporation if its separate existence had continued.

SECTION 11.  Savings  Clause.  If this  Article or any portion  hereof  shall be

investigative,  including  a grand jury  proceeding,  and all  appeals,  and any
action  by the  Corporation,  to the full  extent  permitted  by any  applicable

to any employee benefit plan, its participants,  or beneficiaries;  and a person
who acted in good faith and in a manner such person reasonably believed to be in
the interest of the participants and  beneficiaries of any employee benefit plan
shall be deemed to have acted in a manner not opposed to the best  interests  of

ITEM 17. UNDERTAKINGS

(1)     The undersigned Registrant hereby undertakes:

        (a)     To file,  during any  period in which  offers or sales are being
                made, a post-effective amendment to this registration statement:

                (i)     To include any prospectus  required by Section  10(a)(3)
                        of the Securities Act of 1933;

                (ii)    To reflect in the prospectus any facts or events arising
                        after the effective date of the  registration  statement
                        (or the most recent  post-effective  amendment  thereof)
                        which,  individually  or in the  aggregate,  represent a
                        fundamental  change in the  information set forth in the
                        registration  statement.  Notwithstanding the foregoing,
                        any increase or decrease in volume of securities offered
                        (if the total dollar value of  securities  offered would
                        not exceed that which was  registered) and any deviation
                        from  the  low or  high  and of  the  estimated  maximum
                        offering   range  may  be   reflected  in  the  form  of
                        prospectus  filed with the  Commission  pursuant to Rule
                        424(b) if, in the  aggregate,  the changes in volume and
                        price  represent  no more than 20 percent  change in the
                        maximum  aggregate  offering  price  set  forth  in  the
                        "Calculation  of  the  Registration  Fee"  table  in the
                        effective registration statement;

                (iii)   To include any material  information with respect to the
                        plan of  distribution  not  previously  disclosed in the
                        registration  statement or any  material  change to such
                        information in the registration statement;

        provided,  however, that paragraphs 2(a)(i) and 2(a)(ii) do not apply if
the information  required to be included in a post-effective  amendment by those
paragraphs is contained in periodic reports filed by the Registrant  pursuant to
Section  13 or Section  15(d) of the  Securities  Exchange  Act of 1934 that are
incorporated by reference herein.

        (b)     That,  for the purpose of  determining  any liability  under the
                Securities Act of 1933, each such post-effective amendment shall
                be deemed to be a new  registration  statement  relating  to the
                securities  offered herein,  and the offering of such securities
                at that  time  shall  be  deemed  to be the  initial  BONA  FIDE
                offering thereof.  (c) To remove from registration by means of a
                post-effective  amendment any of the securities being registered
                which remain at the termination of the offering.

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

                                       25

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

Palomar Medical Technologies, Inc.
45 Hartwell Avenue
Lexington, MA 02173

Gentlemen:

        I am  familiar  with the  Registration  Statement  on Form S-3 (the "S-3
Registration  Statement")  to which this  opinion is an exhibit,  to be filed by
Palomar Medical Technologies, Inc., a Delaware corporation (the "Company"), with
the  Securities  and Exchange  Commission  under the  Securities Act of 1933, as
amended. The S-3 Registration  Statement relates to a total of 10,913,109 shares
(the "Shares") of the Company's common stock, $.01 par value per share, issuable
pursuant to certain debentures and a guarantee,  both issued/issuable to certain
entities.

        In arriving at the opinion  expressed  below, I have examined and relied
on the following documents:

        (1)     the  Certificate  of  Incorporation  and By-Laws of the Company,
                each as amended as of the date hereof; and

        (2)     the records of meetings  and  consents of the Board of Directors
                and stockholders of the Company provided to me by the Company.


        In  addition,  I have  examined  and relied on the  originals  or copies
certified or  otherwise  identified  to my  satisfaction  of all such  corporate
records of the  Company and such other  instruments  and other  certificates  of
public  officials,  officers and  representatives  of the Company and such other
persons,  and have made such investigations of law, as I have deemed appropriate
as a basis for the opinion expressed below.

        Based  upon  the  foregoing,  it is my  opinion  that  the  Company  has
corporate  power adequate for the issuance of the Shares.  The Company has taken
all necessary  corporate  action  required to authorize the issuance and sale of
the Shares,  and when  certificates  for the Shares have been duly  executed and
countersigned and delivered,  such Shares will be legally issued, fully paid and
non-assessable.

        I hereby  consent to the filing of this opinion as an exhibit to the S-3
Registration Statement.

                                             Sincerely,



                                             /s/ Sarah Burgess Reed

           6%, 7% AND 8% CONVERTIBLE DEBENTURE DUE SEPTEMBER 30, 2002


        THIS  CONVERTIBLE   DEBENTURE  (this  "DEBENTURE")  is  one  of  a  duly
authorized  issue  of  Debentures  of  Palomar  Medical  Technologies,   Inc.  a
corporation  duly organized and existing under the laws of the State of Delaware
and having its principal address at 66 Cherry Hill Drive, Beverly, Massachusetts

        FOR   VALUE   RECEIVED,    the   Corporation    promises   to   pay   to
______________________,  at the address specified in the Debenture  Register (as

Securities  Purchase  Agreement,  dated as of September  30,  1997,  between the
Corporation and the original Holder (as amended from time to time and in effect,

satisfaction of the Holder.  The principal of and interest on this Debenture are
payable  only in United  States  Dollars at the address  last  appearing  on the
Debenture  Register of the  Corporation  as  designated in writing by the Holder

        This Debenture is subject to the following additional provisions:

                             I. CERTAIN DEFINITIONS

        For  purposes  of this  Debenture,  the  following  terms shall have the
following meanings:

        A.  "CLOSING  BID PRICE"  means,  for any  security as of any date,  the
closing  bid price of such  security  on the  principal  securities  exchange or
trading  market where such security is listed or traded as reported by Bloomberg
Financial  Markets or a  comparable  reporting  service of  national  reputation
selected by the Corporation  and reasonably  acceptable to holders of a majority
of the then outstanding  Debentures if Bloomberg  Financial  Markets is not then
reporting closing bid prices of such security (collectively, "BLOOMBERG"), or if
the foregoing  does not apply,  the last reported sale price of such security in
the  over-the-counter  market on the electronic bulletin board for such security
as reported by Bloomberg,  or, if no sale price is reported for such security by
Bloomberg,  the  average of the bid prices of any  market  makers  chosen by the
Holder for such  security  as  reported  in the "pink  sheets"  by the  National
Quotation  Bureau,  Inc. If the Closing Bid Price cannot be calculated  for such
security on such date on any of the  foregoing  bases,  the Closing Bid Price of
such  security  on such  date  shall be the  fair  market  value  as  reasonably
determined  by an  investment  banking  firm  selected  by the  Corporation  and
reasonably  acceptable  to  holders  of  a  majority  of  the  then  outstanding
Debentures, with the costs of such appraisal to be borne by the Corporation.

        B. "CLOSING  DATE" means the Closing Date under that certain  Securities
Purchase Agreement dated September 30, 1997 by and among the Corporation and the
initial purchasers of the Debentures (the "SECURITIES PURCHASE AGREEMENT").

        C. "COMMON STOCK" shall mean the Common Stock, par value $.01 per share,
of the Corporation.

        D.  "CONVERSION  DATE"  means,  for any  Optional  Conversion,  the date
specified in the notice of optional  conversion in the form attached hereto (the
"NOTICE OF OPTIONAL CONVERSION"),  so long as the copy of the Notice of Optional
Conversion  is faxed (or  delivered  by other means  resulting in notice) to the
Corporation  before  Midnight,  New  York  City  time,  on the  Conversion  Date
indicated  in the  Notice of  Optional  Conversion.  If the  Notice of  Optional
Conversion is not so delivered  before such time, then the Conversion Date shall
be the date the  Holder  delivers  the  Notice  of  Optional  Conversion  to the
Corporation.  In the case of any Mandatory  Conversion,  the  "Conversion  Date"
shall mean the date  specified  in a written  notice (the  "NOTICE OF  MANDATORY
CONVERSION")  delivered by the Corporation to the Holder,  so long as the Notice
of  Mandatory  Conversion  is faxed (or  delivered  by other means  resulting in
notice) to the Holder before  Midnight,  New York City time,  not later than the
20th  trading day  preceding  such  specified  date.  If the Notice of Mandatory
Conversion is not so delivered  before such time, then the Conversion Date shall
be the 20th trading day following the date the  Corporation  delivers the Notice
of Mandatory  Conversion  to the Holder.  As used herein,  a "TRADING DAY" shall
mean any day on which  the  Nasdaq  Stock  Market  (or the  national  securities
exchange or automated quotation system on which the Common Stock is then traded)
is open for  business,  whether or not shares of Common Stock are traded on such
day.

        E.  "CONVERSION  PRICE"  means,  as of any  date of  determination,  the
average of the Closing Bid Prices for the Common Stock for ten (10)  consecutive
trading  days  ending on the  trading  day  immediately  preceding  such date of
determination  (subject to equitable  adjustments  for any stock  splits,  stock
dividends,  reclassifications or similar events during such ten (10) trading day
period), and shall be subject to adjustment as provided herein.

        F.  "OUTSTANDING  AMOUNT " means,  as of any date, the principal  amount
then  outstanding  under this  Debenture  and all  accrued  but unpaid  interest
thereon.

                                 II. CONVERSION

        A.  Conversion at the Option of the Holder;  Conversion at the Option of
the  Corporation.  Subject  to  the  limitations  on  conversions  contained  in
Subparagraphs (i) and (ii) of Paragraph C of this Article II and in subparagraph
(i) of Article  V.C,  all or any portion of the  Outstanding  Amount may, at any
time and from time to time from and after the Closing  Date, be converted at the
option of the Holder (an "OPTIONAL  CONVERSION") into a number of fully paid and
nonassessable  shares of Common Stock equal to the Outstanding Amount divided by
the Conversion  Price then in effect.  Subject to the limitations on conversions
contained in Subparagraph  (iii) of Paragraph C of this Article II, beginning on
the date which is one (1) year after the Closing Date, all or any portion of the
Outstanding  Amount  may be  converted  at the  option  of  the  Corporation  (a
"MANDATORY  CONVERSION") into a number of fully paid and nonassessable shares of
Common Stock equal to the  Outstanding  Amount divided by the  Conversion  Price
then in effect, provided that the Closing Bid Price for the Common Stock on each
of the twenty (20) consecutive  trading days  immediately  preceding the date of
the Notice of Mandatory  Conversion  is equal to or greater than the Closing Bid
Price for the Common Stock on the Closing Date.

                                       31

        B.  Mechanics of  Conversion.  In order to convert this  Debenture  into
shares of Common Stock pursuant to an Optional Conversion, the Holder shall: (x)
deliver (by  facsimile  or  otherwise)  a copy of the fully  executed  Notice of
Optional  Conversion  to the  Corporation  and  (y)  surrender  or  cause  to be
surrendered  this  Debenture  along  with  a  copy  of the  Notice  of  Optional
Conversion as soon as practicable thereafter to the Corporation.  At the request
of the  Holder and upon  receipt by the  Corporation  of a  facsimile  copy of a
Notice of Optional Conversion from the Holder, the Corporation shall immediately
send,  via facsimile,  a confirmation  to such holder stating that the Notice of
Optional  Conversion  has been  received,  the date upon  which the  Corporation
expects to deliver the Common Stock  issuable upon such  conversion and the name
and  telephone  number of a  contact  person at the  Corporation  regarding  the
conversion.  In order to convert  this  Debenture  into  shares of Common  Stock
pursuant to a Mandatory Conversion,  the Corporation shall deliver (by facsimile
or otherwise) a copy of the fully executed Notice of Mandatory Conversion to the
Holder,  which  notice shall  specify the  Outstanding  Amount to be  converted.
Promptly following receipt of a Notice of Mandatory Conversion, the Holder shall
surrender or cause to be  surrendered  this  Debenture as soon as practicable to
the  Corporation.  The  Corporation  shall not be  obligated  to issue shares of
Common Stock  issuable  upon any  Optional  Conversion  or Mandatory  Conversion
unless either this Debenture is delivered to the  Corporation as provided above,
or the holder notifies the Corporation  that such  certificates  have been lost,
stolen or destroyed (subject to the requirements of Article IX.A).

                (i) Delivery of Common Stock Upon  Conversion.  The  Corporation
        shall,  within one trading day after the later of (a) the second trading
        day following the Conversion Date in the case of DWAC deliveries and the
        third trading day following the  Conversion  Date in all other cases and
        (b) the date of surrender of this  Debenture (or, in case this Debenture
        is lost,  stolen or destroyed,  the date on which indemnity  pursuant to
        Article IX.A is provided) (the "DELIVERY PERIOD"),  issue and deliver to
        or upon the  order of the  Holder  (x) that  number  of shares of Common
        Stock issuable upon conversion of the Outstanding Amount being converted
        and (y) a new Debenture  representing  the Outstanding  Amount not being
        converted, if any.

                (ii) Taxes.  The  Corporation  shall pay any and all taxes which
        may be imposed  upon it with respect to the issuance and delivery of the
        shares of Common Stock upon the conversion of this Debenture.

                (iii) No Fractional  Shares. If any conversion of this Debenture
        would  result in the  issuance  of either a  fractional  share of Common
        Stock,  such  fractional  share shall be  disregarded  and the number of
        shares of Common Stock issuable upon  conversion of this Debenture shall
        be the closest whole number of shares.

                (iv)  Status  as  Stockholder.  Upon the  Conversion  Date,  the
        Outstanding Amount being converted shall be deemed converted into shares
        of Common Stock as of the Conversion  Date and the Holder's  rights as a
        holder  of the  Outstanding  Amount  being  converted  shall  cease  and
        terminate,  excepting  only the right to receive  certificates  for such
        shares of Common Stock and to any remedies  provided herein or otherwise
        available at law or in equity to such holder because of a failure by the
        Corporation  to comply with the terms of this  Debenture  (including its
        right to regain its status as a Holder pursuant to Article IV.E).

                (v) Conversion Disputes. In the case of any dispute with respect
        to a conversion,  the  Corporation  shall  promptly issue such number of
        shares  of  Common  Stock  as  are  not  disputed  in  accordance   with
        subparagraph  (i) above. If such dispute involves the calculation of the
        Conversion  Price, the Corporation  shall submit,  at its sole cost, the
        disputed calculations to its outside accountant via facsimile within two
        (2) trading  days of receipt of the Notice of Optional  Conversion.  The
        accountant  shall audit the  calculations and notify the Corporation and
        the Holder of the  results no later than two (2)  trading  days from the
        date it receives the disputed calculations. The accountant's calculation
        shall be deemed conclusive, absent manifest error. The Corporation shall
        then  issue  the  appropriate  number  of  shares  of  Common  Stock  in
        accordance with subparagraph (i) above.

                                       32

         C.  Limitations  on  Conversions.

                (i) In no event shall the Holder be  entitled to receive  shares
        of Common Stock upon an Optional  Conversion  to the extent that the sum
        of (a) the number of shares of Common  Stock  beneficially  owned by the
        Holder and its affiliates  (exclusive of shares issuable upon conversion
        of the  unconverted  portion of this  Debenture  or the  unexercised  or
        unconverted  portion of any other securities of the Corporation  subject
        to a limitation on conversion or exercise  analogous to the  limitations
        contained  herein) and (b) the number of shares of Common Stock issuable
        upon  the  conversion  of this  Debenture  with  respect  to  which  the
        determination  of this  subparagraph  is being  made,  would  result  in
        beneficial  ownership by the holder and its affiliates of more than 4.9%
        of the  outstanding  shares  of  Common  Stock.  For  purposes  of  this
        subparagraph,  beneficial  ownership  shall be  determined in accordance
        with Section 13(d) of the  Securities  Exchange Act of 1934, as amended,
        and Regulation 13 D-G thereunder, except as otherwise provided in clause
        (i) above.  The  provisions of this  subparagraph  shall  terminate upon
        delivery by the Holder of a Mandatory Prepayment Notice. The Corporation
        shall be entitled to rely, and shall be fully  protected in relying,  on
        any statement or representation made by the Holder to the Corporation in
        connection  with a particular  conversion  without any obligation on the
        part of the  Corporation  to make any  inquiry  or  investigation  or to
        examine its records or the records of any transfer  agent for the Common
        Stock.

                (ii)  During any  thirty  (30) day  period  ending  prior to the
        earlier of (a) that date which is two  hundred and nine (209) days after
        the  Closing  Date and (b)  that  date  (if  any)  that the  Corporation
        delivers an Optional  Prepayment Notice (as defined below) to the Holder
        pursuant to clause (b) of  subparagraph  (i) of Article  V.C, the Holder
        may not  effect  an  Optional  Conversion  with  respect  to  more  than
        thirty-three  percent  (33%) of the  original  principal  amount of this
        Debenture  (and the  accrued  but unpaid  interest  thereon);  provided,
        however,  if the Holder has already converted sixty-six percent (66%) of
        such  original  principal  amount,  the Holder may convert the remaining
        thirty-four  percent  (34%) of the  original  principal  amount  of this
        Debenture  (and the  accrued  but unpaid  interest  thereon) in the next
        succeeding thirty (30) day period or thereafter.

                (iii) The  Corporation  may not  effect a  Mandatory  Conversion
        pursuant  to this  Article  II  unless,  on the  date of the  Notice  of
        Mandatory  Conversion  and on the date of  delivery  of such  Conversion
        Shares,  (a) a registration  statement under the Securities Act of 1933,
        as  amended,  covering  the resale of the  Common  Stock  issuable  upon
        conversion  of this  Debenture  is in effect which names the Holder as a
        selling  stockholder;  (b) the  Corporation  has  reserved the number of
        shares of Common Stock required by Article III; (c) the  Corporation has
        paid in full any liquidated  damages  hereunder;  and (d) the Holder has
        not, prior to such date,  delivered a Mandatory Prepayment Notice to the
        Corporation.

                   III. RESERVATION OF SHARES OF COMMON STOCK

        The Corporation  shall at all times have authorized and reserved for the
purpose of issuance a sufficient number of shares of Common Stock to provide for
the full  conversion of the  outstanding  Debentures  in  accordance  with their
terms.

                       IV. FAILURE TO SATISFY CONVERSIONS

        A. Conversion Default Payments.  If, at any time, (x) the Holder submits
a Notice of  Optional  Conversion  and the  Corporation  fails for any reason to
deliver,  on or prior to the first trading day  following the  expiration of the
Delivery  Period for such  conversion,  the shares of Common  Stock to which the
Holder is entitled  upon such  conversion in the manner  required  hereunder and
under the Purchase  Agreement,  or (y) the  Corporation  provides  notice to any
holder of the  Debentures  at any time of its  intention  not to issue shares of
Common Stock upon exercise by any holder of its conversion  rights in accordance
with  the  terms of the  Debentures  (each  of (x) and (y)  being a  "CONVERSION
DEFAULT"),  then the Corporation  shall pay to the Holder payments for the first
ten (10) trading days  following the expiration of the Delivery  Period,  in the
case of a Conversion Default described in clause (x), and for the first ten (10)
trading days of any other Conversion Default, an amount equal to $1,000 per day.
In the event any Conversion  Default  continues beyond such ten (10) trading day
period,  the Holder shall be entitled to interest on the Outstanding Amount at a
rate per annum equal to the lower of  twenty-four  percent (24%) and the highest
rate permitted by applicable law from the expiration of the ten (10) trading day
period described above through and including the Default Cure Date. In addition,
upon the occurrence of any Conversion Default, the Holder may, by written notice
to the  Corporation,  elect to revoke  any  Optional  Conversion  and obtain the
return of the  unconverted  Debenture.  As used herein,  the "DEFAULT CURE DATE"
means (i) with  respect to a Conversion  Default  described in clause (x) of its
definition,  the  date  the  Corporation  effects  the  conversion  of the  full
Outstanding  Amount  requested  to be  converted  and  (ii)  with  respect  to a
Conversion  Default  described  in clause  (y) of its  definition,  the date the
Corporation  begins to honor  conversions of the  Debentures in accordance  with
their terms.

                                       33
<PAGE>

        The  payments  to which the Holder  shall be  entitled  pursuant to this
Paragraph A are referred to herein as "CONVERSION DEFAULT PAYMENTS" and shall be
liquidated  damages and not penalties.  The Holder may elect to receive  accrued
Conversion  Default  Payments  in cash or to convert  all or any portion of such
accrued  Conversion  Default  Payments,  at any time,  into Common  Stock at the
Conversion  Price in  effect  at the time of such  conversion.  In the event the
Holder elects to receive any  Conversion  Default  Payments in cash, it shall so
notify the Corporation in writing. Such payment shall be made in accordance with
and be subject to the provisions of Article IX.D. In the event the Holder elects
to convert all or any portion of the  Conversion  Default  Payments,  the Holder
shall indicate on a Notice of Optional Conversion such portion of the Conversion
Default Payments which the Holder elects to so convert and such conversion shall
otherwise be effected in accordance with the provisions of Article II.

        B.  Adjustment  to  Conversion  Price.  If the Holder  has not  received
certificates  for all shares of Common Stock prior to the tenth  (10th)  trading
day after the expiration of the Delivery  Period with respect to a conversion of
this  Debenture  for any reason,  then the  Conversion  Price in respect of this
Debenture  shall  thereafter  be the lesser of (i) the  Conversion  Price on the
Conversion Date specified in the Notice of Optional Conversion which resulted in
the Conversion Default and (ii) the lowest Conversion Price in effect during the
period  beginning on, and including,  such Conversion Date through and including
the day such shares of Common Stock are delivered to the Holder.  If there shall
occur a Conversion  Default of the type described in clause (y) of Article IV.A,
then the Conversion Price with respect to any conversion thereafter shall be the
lower of (x) the lowest Conversion Price in effect at any time during the period
beginning  on, and  following,  the date of the  occurrence  of such  Conversion
Default through and including the Default Cure Date and (y) the Conversion Price
on the Conversion  Date specified in the Notice of Optional  Conversion for this
Debenture.   The  Conversion  Price  shall  thereafter  be  subject  to  further
adjustment for any events described in Article VI.

        C. Buy-In Cure. If (i) the  Corporation  fails for any reason to deliver
during  the  Delivery  Period  shares  of  Common  Stock  to the  Holder  upon a
conversion of this Debenture having a Conversion Date on or prior to a date upon
which the Corporation has notified the Holder in writing that the Corporation is
unable to honor  conversions and (ii) after the applicable  Delivery Period with
respect to such conversion,  the Holder purchases (in an open market transaction
or  otherwise)  shares of Common Stock to deliver in  satisfaction  of a sale by
such holder of the shares of Common Stock which the Holder anticipated receiving
upon such  conversion (a  "BUY-IN"),  the  Corporation  shall pay the Holder (in
addition to any other remedies  available to the Holder) the amount by which (x)
the Holder's total purchase price (including brokerage commissions,  if any) for
the  shares  of  Common  Stock  so  purchased  exceeds  (y) the  portion  of the
Outstanding Amount resulting in the Buy-In. For example, if the Holder purchases
shares of Common  Stock  having a total  purchase  price of  $11,000  to cover a
Buy-In with respect to an attempted  conversion of a total Outstanding Amount of
$10,000,  the Corporation will be required to pay the Holder $1,000.  The Holder
shall  provide  the  Corporation  written  notification  indicating  any amounts
payable to the Holder pursuant to this Paragraph C. The  Corporation  shall make
any  payments  required  pursuant  to this  Paragraph C in  accordance  with and
subject to the provisions of Article IX.D.

        D.  Mandatory  Prepayment  Right.  If the  Corporation  fails,  and such
failure  continues  uncured for five (5) trading days after the  Corporation has
been notified  thereof in writing by the Holder,  for any reason to issue shares
of Common  Stock  within  ten (10)  trading  days  after the  expiration  of the
Delivery  Period with  respect to any  conversion  of this  Debenture,  then the
Holder  may elect at any time and from time to time  prior to the  Default  Cure
Date for such Conversion Default,  by delivery of a Mandatory  Prepayment Notice
(as  defined  in  Article  V.B) to the  Corporation,  to demand  payment  by the
Corporation  in cash of all or any  portion of the  Outstanding  Amount.  If the
Corporation  fails to make such  payment  within five (5) trading days after its
receipt of a Mandatory  Prepayment Notice,  then the Holder shall be entitled to
the remedies provided in Article V.B.

        E.  Retention  of Rights as  Debenture  Holder.  If the  Holder  has not
received  certificates  for all shares of Common Stock prior to the tenth (10th)
trading  day after the  expiration  of the  Delivery  Period  with  respect to a
conversion of this Debenture for any reason, then the Corporation shall, as soon
as  practicable,  return  this  Debenture  to the Holder and  (unless the Holder
otherwise  elects to retain its  status as a holder of Common  Stock) the Holder
shall regain the rights of a holder of this Debenture.  In all cases, the Holder
shall retain all of its rights and remedies (including,  without limitation, (i)
the right to receive  Conversion  Default Payments pursuant to Paragraph A above
to the extent required  thereby for such  Conversion  Default and any subsequent
Conversion  Default and (ii) the right to have the Conversion Price with respect
to subsequent  conversions  determined in accordance with Paragraph B above) for
the Corporation's failure to convert this Debenture.

                       V. PREPAYMENT DUE TO CERTAIN EVENTS

        A. Mandatory  Prepayment.  In the event (each of the events described in
clauses  (i)-(v) below after  expiration of the applicable  cure period (if any)
being a "MANDATORY PREPAYMENT EVENT"):

                (i) the  Common  Stock  (including  all of the  shares of Common
        Stock  issuable  upon  conversion of this  Debenture) is suspended  from
        trading on any of, or is not listed or  designated  for  quotation  (and
        authorized) for trading on at least one of, the New York Stock Exchange,
        the American Stock  Exchange,  the NASDAQ  National Market or the NASDAQ
        Small Cap Market  ("NASDAQ")  for an  aggregate of five (5) full trading
        days in any nine (9) month period,

                (ii)  the  Registration  Statement  required  to be filed by the
        Corporation   pursuant  to  Section  2(a)  of  the  Registration  Rights
        Agreement,  dated as of September 30, 1997, by and among the Corporation
        and the other signatories thereto (the "REGISTRATION RIGHTS AGREEMENT"),
        has not been  declared  effective by the 180th day following the Closing
        Date or such  Registration  Statement,  after being declared  effective,
        cannot  be  utilized  by the  Holder  for  the  resale  of all of  their
        Registrable Securities (as defined in the Registration Rights Agreement)
        for an aggregate of more than thirty (30) days in any consecutive twelve
        month  period  as a  result  of (x)  the  inclusion  in  the  prospectus
        contained  in such  Registration  Statement  of an untrue  statement  of
        material fact or omission to state a material fact required to be stated
        therein or necessary to make the statements  therein not misleading,  or
        (y) the issuance of any stop order or other  suspension of effectiveness
        of such Registration Statement.

                (iii) the  Corporation  fails,  and any such  failure  continues
        uncured  for  five (5)  trading  days  after  the  Corporation  has been
        notified  thereof in writing by the  Holder,  to remove any  restrictive
        legend on any  certificate  or any shares of Common  Stock issued to the
        Holder upon  conversion  of this  Debenture as and when required by this
        Debenture,  the Securities Purchase Agreement or the Registration Rights
        Agreement,

                (iv)  the  Corporation  provides  notice  to any  holder  of the
        Debentures, including by way of public announcement, at any time, of its
        intention  not to issue  shares  of Common  Stock to any  holder of said
        Debentures upon conversion in accordance with the terms thereof,

                (v) the Corporation shall:

                        (a) sell,  convey or dispose of all or substantially all
                of its assets;

                        (b) merge,  consolidate  or engage in any other business
                combination   with  any  other  entity  (other  than  a  merger,
                consolidation  or business  combination  in which the holders of
                the Corporation's voting securities  immediately  preceding such
                merger, consolidation or business combination own, on a pro rata
                basis,   at  least  50%  of  the   surviving   entity's   voting
                securities); or

                        (c) have fifty percent (50%) or more of the voting power
                of its capital stock owned beneficially by one person, entity or
                "group"  (as  such  term  is used  under  Section  13(d)  of the
                Securities Exchange Act of 1934, as amended),

                (vi)  Bankruptcy,  reorganization,   insolvency  or  liquidation
        proceedings or other proceedings,  or relief under any bankruptcy law or
        any law for the relief of debt  shall be  instituted  by or against  the
        Company and, if instituted  against the Company,  shall not be dismissed
        within ninety (90) days after such institution,  or the Company shall by
        any action or answer  approve of,  consent to, or  acquiesce in any such
        proceedings  or admit to any  material  allegations  of, or  default  in
        answering a petition filed in, any such proceeding,

                (vii) the  Corporation  shall  fail to  comply  in any  material
        respect  with the  agreements  and  covenants  contained in the Purchase
        Agreement,   the   Registration   Rights  Agreement  or  this  Debenture
        (including  without  limitation a failure to comply with its  conversion
        obligations hereunder),  which failure continues uncured for a period of
        ten (10) days following delivery of written notice thereof by the Holder
        to the Corporation,

                                       35
<PAGE>

                (viii) the Corporation shall fail to pay when due any amount due
        hereunder free of any claim of subordination, or

                (ix) the Corporation shall be prohibited from complying with its
        conversion  obligations  hereunder by reason of any stockholder approval
        requirements of NASDAQ,

then,  upon the occurrence of any such Mandatory  Prepayment  Event,  the Holder
shall  thereafter  have the option,  exercisable in whole or in part at any time
and from time to time by delivery of a Mandatory  Prepayment  Notice (as defined
in Paragraph B below) to the Corporation  while such Mandatory  Prepayment Event
continues,  to  require  the  Corporation  to  pay  in  cash  any  or all of the
Outstanding  Amount.  For the  avoidance of doubt,  the  occurrence of any event
described  in  clauses  (i),  (ii),  (iv),  (v),  (vii)  and  (ix)  above  shall
immediately  constitute a Mandatory  Prepayment Event and there shall be no cure
period.

        B. Mandatory  Prepayment  Defaults.  If, within five (5) trading days of
the  Corporation's  receipt of a notice from the Holder  identifying a Mandatory
Prepayment  Event that has occurred and requiring the  Corporation to pay any or
all of the Outstanding Amount (a "MANDATORY PREPAYMENT NOTICE"), the Corporation
fails to pay to the Holder the  Outstanding  Amount  specified in the  Mandatory
Prepayment  Notice,  the  Holder  (i)  shall be  entitled  to  interest  on such
Outstanding Amount at a per annum rate equal to the lower of twenty-four percent
(24%) and the highest  rate  permitted  by  applicable  law from the date of the
Mandatory Prepayment Notice until the date of payment hereunder,  and (ii) shall
have the right,  at any time and from time to time, to require the  Corporation,
upon written  notice,  to immediately  convert (in accordance  with the terms of
Paragraph A of Article II) all or any  portion of such  Outstanding  Amount into
shares of Common  Stock at the  lowest  Conversion  Price in effect  during  the
period  beginning on the date of the Mandatory  Prepayment  Notice and ending on
the Conversion Date with respect to the conversion of such  Outstanding  Amount.
In the event the Corporation is not able to pay all of the Debentures subject to
Mandatory Prepayment Notices, the Corporation shall pay the Debentures pro rata,
based on the total  Outstanding  Amount  under the  Debentures  included by each
holder in the  Mandatory  Prepayment  Notice  relative to the total  Outstanding
Amount under the Debentures in all of the Mandatory Prepayment Notices.

        C. Optional Prepayment.

                (i) At any  time (a) on or  before  that  date  which is six (6)
        months  after the Closing Date or (b) on or after that date which is one
        (1) year after the Closing Date, the Corporation shall have the right to
        prepay  ("OPTIONAL  PREPAYMENT")  all or any portion of the  Outstanding
        Amount, provided,  however, that any such prepayment shall be subject to
        concurrent payment of a premium (the "OPTIONAL  PREPAYMENT PREMIUM") and
        all other amounts owing hereunder.  An Optional Prepayment shall be made
        by the  Corporation  in its sole  discretion  by delivery of an Optional
        Prepayment  Notice  (as  defined  below).  In the  case  of an  Optional
        Prepayment   during  the  period   described   in  clause  (a)  of  this
        subparagraph,  the  Optional  Prepayment  Premium  shall be in an amount
        equal to seven and one half  percent  (7 1/2%) of the  principal  amount
        being  prepaid and the Holder's  right to effect an Optional  Conversion
        shall terminate upon receipt of an Optional  Prepayment  Notice.  In the
        case of an Optional Prepayment during the period described in clause (b)
        of this  subparagraph,  the Optional  Prepayment  Premium shall be in an
        amount equal to ten percent (10%) of the principal  amount being prepaid
        and the Holder may  convert  all or any part of the  Outstanding  Amount
        into Common Stock by  delivering a Notice of Optional  Conversion to the
        Corporation  at any time  prior to that date  which is ten (10)  trading
        days after receipt of an Optional Prepayment Notice.

                (ii) The  Corporation  shall effect each  prepayment  under this
        Section  VIII.B by giving  at least  twenty  (20)  trading  days'  prior
        written notice (the "OPTIONAL  PREPAYMENT  NOTICE") of the date on which
        such prepayment is to be made (the "OPTIONAL  PREPAYMENT  DATE") and the
        Outstanding  Amount  to be  prepaid  to the  Holder at the  address  and
        facsimile  number of the Holder  appearing  in the  Debenture  Register,
        which Optional  Prepayment Notice shall be deemed to have been delivered
        on the  trading  day  after the  Corporation's  fax (with a copy sent by
        overnight  courier) of such notice to the Holder.  The Corporation shall
        pay the Outstanding Amount specified in the Optional  Prepayment Notice,
        together with the applicable  Optional Prepayment Premium, to the Holder
        on the Optional  Prepayment  Date.  The  Corporation  may not attempt to
        deliver an Optional  Prepayment  Notice if it has previously  received a
        Mandatory Prepayment Notice.

                                       36
<PAGE>

                (iii) If the Corporation  fails to pay, when due and owing,  any
        portion of the Outstanding Amount or the Optional  Prepayment Premium in
        accordance  with an Optional  Prepayment  Notice,  then the Holder shall
        have  the  right,  at any time and from  time to time,  to  require  the
        Corporation,  upon written notice, to immediately convert (in accordance
        with  the  terms  of  paragraph  A of  Article  II)  any  or  all of the
        Outstanding  Amount which is the subject of such  prepayment into shares
        of Common  Stock at the  lowest  Conversion  Price in effect  during the
        period  beginning  on the date of the  Optional  Prepayment  Notice  and
        ending  on  the  earlier  of  the  date  the  Corporation  effects  such
        prepayment in full and the date of the Holder's notice of conversion.

                     VI. ADJUSTMENTS TO THE CONVERSION PRICE

        The Conversion Price shall be subject to adjustment from time to time as
follows:

        A.  Adjustment Due to Major  Announcement.  In the event the Corporation
(i) makes a public announcement that it intends to consolidate or merge with any
other entity (other than a merger in which the  Corporation  is the surviving or
continuing entity and its capital stock is unchanged) or to sell or transfer all
or substantially all of the assets of the Corporation or (ii) any person,  group
or entity  (including  the  Corporation)  publicly  announces a tender  offer to
purchase  50% or  more  of the  Corporation's  Common  Stock  (the  date  of the
announcement  referred  to  in  clause  (i)  or  (ii)  of  this  Paragraph  A is
hereinafter  referred to as the "ANNOUNCEMENT  DATE"), then the Conversion Price
shall,   effective  upon  the  Announcement  Date  and  continuing  through  the
Abandonment  Date  (as  defined  below),  be  equal  to the  lesser  of (x)  the
Conversion  Price which would have been  applicable  for an Optional  Conversion
occurring on the Announcement Date and (y) the Conversion Price which would have
been  applicable for an Optional  Conversion  occurring on the Conversion  Date.
From and after the Abandonment Date, the Conversion Price shall be determined as
set forth in Article I.E.  "ABANDONMENT DATE" means with respect to any proposed
transaction or tender offer for which a public  announcement  as contemplated by
this Paragraph A has been made, the date upon which the Corporation (in the case
of clause (i) above) or the person,  group or entity (in the case of clause (ii)
above)  publicly  announces  the  termination  or  abandonment  of the  proposed
transaction or tender offer which caused this Paragraph A to become operative.

        B.  Adjustment Due to Merger,  Consolidation,  Etc. If, at any time when
this Debenture is outstanding, there shall be (i) any reclassification or change
of the outstanding  shares of Common Stock (other than a change in par value, or
from par  value to no par  value,  or from no par  value to par  value,  or as a
result of a subdivision or combination), (ii) any consolidation or merger of the
Corporation  with any other entity (other than a merger in which the Corporation
is the surviving or continuing entity and its capital stock is unchanged), (iii)
any  sale  or  transfer  of  all or  substantially  all  of  the  assets  of the
Corporation or (iv) any share exchange  pursuant to which all of the outstanding
shares of Common Stock are converted into other securities or property, then the
Holder shall  thereafter have the right to receive upon  conversion,  in lieu of
the shares of Common Stock  immediately  theretofore  issuable  (without  giving
effect to any limitations upon conversion  imposed by Article II.C), such shares
of stock,  securities  and/or  other  property as may be issued or payable  with
respect to or in exchange for the number of shares of Common  Stock  immediately
theretofore  issuable upon conversion  (without giving effect to any limitations
upon  conversion  imposed  by  Article  II.C)  had such  merger,  consolidation,
exchange of shares, recapitalization,  reorganization or other similar event not
taken place,  and in any such case,  appropriate  provisions  shall be made with
respect to the rights and interests of the Holder to the end that the provisions
hereof  (including,  without  limitation,   provisions  for  adjustment  of  the
Conversion  Price and of the  number of shares  of Common  Stock  issuable  upon
conversion of this Debenture) shall  thereafter be applicable,  as nearly as may
be  practicable  in  relation  to any shares of stock or  securities  thereafter
deliverable upon the conversion  thereof.  The Corporation  shall not effect any
transaction  described  in this  Paragraph B unless (i) the Holder has  received
written notice of such transaction at least ten (10) days prior thereto,  but in
any event on or before the record  date for the  determination  of  shareholders
entitled to vote with  respect  thereto,  and (ii) the  resulting  successor  or
acquiring  entity (if not the  Corporation)  assumes by written  instrument  the
obligations of this Paragraph B. The above  provisions shall apply regardless of
whether  or not there  would have been a  sufficient  number of shares of Common
Stock  authorized  and available for issuance upon  conversion of the Debentures
outstanding as of the date of such  transaction,  and shall  similarly  apply to
successive reclassifications, consolidations, mergers, sales, transfers or share
exchanges.

        C. Purchase  Rights.  If at any time when this Debenture is outstanding,
the Corporation  issues any Convertible  Securities or rights to purchase stock,
warrants,  securities or other property (the "PURCHASE  Rights") pro rata to the
record holders of any class of Common Stock, then the Holder will be entitled to
acquire,  upon the terms  applicable  to such  Purchase  Rights,  the  aggregate
Purchase  Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock  acquirable  upon  complete  conversion of this
Debenture  (without giving effect to any limitations upon conversion  imposed by
Article  II.C)  immediately  before  the date on which a record is taken for the
grant, issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of which the record holders of Common Stock are to be determined for
the grant, issue or sale of such Purchase Rights.


                                       37
<PAGE>

        D. Notice of  Adjustments.  Upon the  occurrence  of each  adjustment or
readjustment  of  the  Conversion   Price  pursuant  to  this  Article  VI,  the
Corporation,   at  its  expense,  shall  promptly  compute  such  adjustment  or
readjustment  and prepare and furnish to the Holder a certificate  setting forth
such adjustment or readjustment  and showing in detail the facts upon which such
adjustment or readjustment is based.  The  Corporation  shall,  upon the written
request at any time of the  Holder,  furnish  to the  Holder a like  certificate
setting forth (i) such adjustment or readjustment,  (ii) the Conversion Price at
the time in  effect  and (iii)  the  number  of  shares of Common  Stock and the
amount,  if any,  of other  securities  or  property  which at the time would be
received upon conversion of this Debenture.

                               VII. NOTICE RIGHTS

        The Corporation shall provide the Holder, at its request, with copies of
proxy materials and other  information sent to shareholders.  If the Corporation
takes a record of its shareholders  for the purpose of determining  shareholders
entitled to (a) receive payment of any dividend or other distribution, any right
to subscribe  for,  purchase or otherwise  acquire  (including by way of merger,
consolidation  or  recapitalization)  any  share  of  any  class  or  any  other
securities  or  property,  or to  receive  any  other  right,  or (b) to vote in
connection with any proposed sale,  lease or conveyance of all or  substantially
all of the assets of the  Corporation,  or any proposed  merger,  consolidation,
liquidation, dissolution or winding up of the Corporation, the Corporation shall
mail a notice to the Holder,  on or before the record date specified therein (or
ten (10) days prior to the  consummation of the transaction or event,  whichever
is earlier,  but in no event earlier than public  announcement  of such proposed
transaction),  of the  date on  which  any such  record  is to be taken  for the
purpose of such vote, dividend,  distribution, right or other event, and a brief
statement   regarding  the  amount  and   character  of  such  vote,   dividend,
distribution, right or other event to the extent known at such time.

                           VIII. PROTECTION PROVISIONS

        So long as this Debenture is  outstanding,  the  Corporation  shall not,
without first obtaining the approval (by vote or written consent) of the holders
of all of the then Outstanding Amount under all Debentures:

        (a)     adversely alter or change the rights,  preferences or privileges
                of the Debentures; or

        (b)     alter or change the rights,  preferences  or  privileges  of any
                capital stock of the  Corporation so as to affect  adversely the
                Debentures.



                                IX. MISCELLANEOUS

        A. Lost or Stolen  Debentures.  Upon receipt by the  Corporation  of (i)
evidence of the loss,  theft,  destruction  or mutilation of this  Debenture and
(ii) (y) in the case of loss,  theft or  destruction,  of  indemnity  reasonably
satisfactory  to  the  Corporation,  or  (z) in the  case  of  mutilation,  upon
surrender and cancellation of this Debenture,  the Corporation shall execute and
deliver a new Debenture of like tenor and date.  However,  the Corporation shall
not be  obligated  to reissue  this  Debenture  if the Holder  contemporaneously
requests the Corporation to convert this Debenture.

        B. [Intentionally omitted.]

        C.  Statements  of  Available  Shares.  So  long as  this  Debenture  is
outstanding,  the  Corporation  shall  deliver  to the  Holder a written  report
notifying it of any  occurrence  which  prohibits the  Corporation  from issuing
Common Stock upon any conversion.  In addition,  the Corporation  shall provide,
within ten (10) days after delivery to the  Corporation of a written  request by
the Holder, any of the following information as of the date of such request: (i)
the total  Outstanding  Amount  under all  Debentures,  (ii) the total number of
shares of Common Stock issued upon all prior conversions of the Debentures,  and
(iii) the total number of shares of Common Stock which are reserved for issuance
upon conversion of the Debentures.

                                       38
<PAGE>

        D. Payment of Cash;  Defaults.  Whenever the  Corporation is required to
make any cash  payment  to the  Holder  under this  Debenture  (as a  Conversion
Default Payment, upon Mandatory or Optional Prepayment or otherwise),  such cash
payment shall be made within five (5) trading days after  delivery by the Holder
of a notice  specifying  that the Holder  elects to receive such payment in cash
and the method (E.G.,  by check,  wire transfer) in which such payment should be
made. If such payment is not delivered  within such five (5) trading day period,
the Holder shall  thereafter  be entitled to interest on the unpaid  amount at a
per annum rate equal to the lower of  twenty-four  percent (24%) and the highest
rate  permitted  by  applicable  law  until  such  amount is paid in full to the
Holder.  This provision  shall not operate to add any  additional  grace or cure
period to any grace or cure period expressly set for in this Debenture.

        E. Remedies Cumulative. The remedies provided in this Debenture shall be
cumulative and in addition to all other remedies available under this Debenture,
at law or in equity  (including  a decree of specific  performance  and/or other
injunctive relief),  and nothing herein shall limit the Holder's right to pursue
actual  damages for any failure by the  Corporation  to comply with the terms of
this  Debenture.  The  Corporation  acknowledges  that  a  breach  by it of  its
obligations  hereunder  will cause  irreparable  harm to the Holder and that the
remedy at law for any such breach may be inadequate.  The Corporation  therefore
agrees, in the event of any such breach or threatened  breach,  the Holder shall
be  entitled,  in addition to all other  available  remedies,  to an  injunction
restraining  any breach,  without the  necessity  of showing  economic  loss and
without any bond or other security being required.

        F.  Obligations  Absolute.  No provision of this  Debenture,  other than
conversion  as  provided  herein,  shall alter or impair the  obligation  of the
Corporation,  which is absolute and unconditional,  to pay the principal of, and
interest  on, this  Debenture  at the time,  place and rate,  and in the manner,
herein prescribed.

        G.  Waivers of Demand,  Etc. The  Corporation  hereby  expressly  waives
demand and presentment  for payment,  notice of nonpayment,  protest,  notice of
protest,  notice of dishonor,  notice of intent to  accelerate,  prior notice of
bringing of suit and  diligence in taking any action to collect  amounts  called
for hereunder and will be directly and primarily  liable for the payments of all
sums owing and to be owing hereon,  regardless of and without any notice (except
as  required  by law),  diligence,  act or  omission  as or with  respect to the
collection of any amount called for hereunder.

        H. Savings Clause.  In case any provision of this Debenture is held by a
court of competent jurisdiction to be excessive in scope or otherwise invalid or
unenforceable, such provision shall be adjusted rather than voided, if possible,
so that it is enforceable to the maximum extent  possible,  and the validity and
enforceability of the remaining provisions of this Debenture will not in any way
be affected or impaired thereby.

        I. Entire  Agreement;  Amendments.  This  Debenture  and the  agreements
referred to in this Debenture  constitute the full and entire  understanding and
agreement  between the  Corporation  and the Holder with  respect to the subject
hereof and,  except as  specifically  set forth  herein or therein,  neither the
Corporation  nor the Holder  makes any  representation,  warranty,  covenant  or
undertaking with respect to such matters. Any provision of this Debenture may be
waived or amended only by an instrument in writing signed by the Corporation and
by all holders of the then Outstanding Amount under all of the Debentures.

        J.  Assignment,  Etc.  The Holder may,  subject to  compliance  with the
Securities  Purchase  Agreement and the Registration  Rights Agreement,  without
prior notice,  transfer or assign this Debenture or any interest  herein (but in
no event in an amount less than $100,000 in Outstanding  Amount or, if less than
$100,000,  the total  Outstanding  Amount hereof) and may mortgage,  encumber or
transfer  any of its rights or  interest  in and to this  Debenture  or any part
hereof,  and each  assignee,  transferee  and  mortgagee  (which may include any
affiliate  of the  Holder)  shall  have the right to so  transfer  or assign its
interest.  Each such assignee,  transferee  and mortgagee  shall have all of the
rights and  obligations  of the Holder  under this  Debenture.  The  Corporation
agrees that,  subject to compliance with the Securities  Purchase  Agreement and
the Registration  Rights Agreement,  after receipt by the Corporation of written
notice  of  assignment  from the  Holder  or from  the  Holders'  assignee,  all
principal,  interest, and other amounts which are then due and thereafter become
due under this Debenture  shall be paid to such assignee at the place of payment
designated in such notice.  This Debenture shall be binding upon the Corporation
and its  successors  and  shall  inure  to the  benefit  of the  Holder  and its
successors  and  assigns.  The  Corporation  may  not  transfer  or  assign  its
obligation  under this  Debenture  without the consent of the Holder;  provided,
however,  that a merger,  consolidation or similar  business  combination of the
Corporation  or the  sale  of  all or  substantially  all of the  assets  of the
Corporation shall not constitute a transfer or assignment.

                                       39
<PAGE>

        K. No Waiver.  No failure on the part of the Holder to exercise,  and no
delay in exercising,  any right,  remedy or power  hereunder  shall operate as a
waiver  thereof,  nor shall any single or partial  exercise by the Holder of any
right,  remedy or power  hereunder  preclude any other or future exercise of any
other  right,  remedy or power.  Each and every  right,  remedy or power  hereby
granted  to the  Holder  or  allowed  it by  law or  other  agreement  shall  be
cumulative  and not  exclusive of any other,  and may be exercised by the Holder
from time to time.

        L. Miscellaneous.  Unless otherwise provided herein, any notice or other
communication  to a party  hereunder  shall be deemed to have been duly given if
personally  delivered or sent by registered or certified  mail,  return  receipt
requested,  postage prepaid with a copy in each case sent on the same day to the
party by facsimile,  Federal Express or other such expedited means to said party
at its address set forth  herein or such other  address as either may  designate
for  itself in such  notice to the other and  communications  shall be deemed to
have been received when delivered  personally or, if sent by mail, when actually
received  by the party to whom it is  addressed.  Copies of all  notices  to the
Corporation  shall  be sent  to  Paul S.  Weiner,  Director  of  Finance  of the
Corporation,  and to the  attention of the General  Counsel of the  Corporation.
Whenever the sense of this  Debenture  requires,  words in the singular shall be
deemed to include the plural and words in the plural  shall be deemed to include
the singular.  Paragraph  headings are for convenience only and shall not affect
the meaning of this document.

        M.  Choice of Law and Venue.  This  Debenture  shall be  governed by and
construed in  accordance  with the laws of the State of Delaware  applicable  to
contracts  made and to be performed in the State of  Delaware.  The  Corporation
irrevocably  consents to the  jurisdiction  of the United States  federal courts
located in the County of Kent in the State of Delaware in any suit or proceeding
based on or arising under this Debenture and irrevocably  agrees that all claims
in respect of such suit or  proceeding  may be  determined  in such courts.  The
Corporation  irrevocably  waives  the  defense of an  inconvenient  forum to the
maintenance  of such suit or  proceeding.  The  Corporation  further agrees that
service  of process  upon the  Corporation  mailed by first  class mail shall be
deemed in every respect effective service of process upon the Corporation in any
suit or proceeding arising  hereunder.  Nothing herein shall affect the Holder's
right to serve  process in any other manner  permitted  by law. The  Corporation
agrees that a final non-appealable judgment in any such suit or proceeding shall
be  conclusive  and  may be  enforced  in  other  jurisdictions  by suit on such
judgment or in any other lawful manner.

        N. Usury Laws.  In no event shall any  provision  of this  Debenture  be
deemed to permit the Holder to  receive  any  payment,  whether of  interest  or
otherwise,  to the  extent  that  such  payment  would be  prohibited  under any
applicable  usury law or similar law  regarding  the rates of  interest  legally
chargeable or collectible hereunder.

                  [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK]


        IN  WITNESS  WHEREOF,  this  Debenture  is  executed  on  behalf  of the
Corporation as of the 30th day of September, 1997.

                        b.  Capitalized  terms  used  herein  and not  otherwise
                defined herein shall have the  respective  meanings set forth in
                the Securities Purchase Agreement.

                2. REGISTRATION.

                        a.  Mandatory  Registration.  The Company shall prepare,
                and,  on or prior to the  sixtieth  (60th) day after the Closing
                Date  (the  "FILING  DATE"),  file  with the SEC a  Registration
                Statement on Form S-3 (or, if Form S-3 is not then available, on
                such form of  Registration  Statement  as is then  available  to
                effect  a  registration  of all of the  Registrable  Securities,
                subject to the reasonable consent of the Investors) covering the
                resale  of a  number  of  Registrable  Shares  equal to at least
                3,500,000 shares plus the amount of Common Shares (provided that
                such  number  may  be   proportionally   reduced  if  less  than
                $7,000,000 in principal  amount of  Debentures  are issued under
                the   Securities   Purchase   Agreement),   which   Registration
                Statement,  to the extent allowable under the Securities Act and
                the Rules  promulgated  thereunder  (including Rule 416),  shall
                state  that  such   Registration   Statement  also  covers  such
                indeterminate number of additional shares of Common Stock as may
                become  issuable upon  conversion  of the  Debentures to prevent
                dilution resulting from stock splits, stock dividends or similar
                transactions  or as a result of fluctuations in the market price
                of the Common Stock. The Registrable  Securities included on the
                Registration  Statement  shall be allocated to the  Investors as
                set forth in Section 11(k) hereof.  The  Registration  Statement
                (and each amendment or supplement thereto,  and each request for
                acceleration of effectiveness thereof) shall be provided to (and
                subject to the reasonable approval of) the Initial Investors and
                their counsel prior to its filing or other submission.

                        b. Underwritten  Offering. If any offering pursuant to a
                Registration  Statement pursuant to Section 2(a) hereof involves
                an underwritten  offering,  the Investors who hold a majority in
                interest  of  the   Registrable   Securities   subject  to  such
                underwritten   offering,   with  the   consent  of  the  Initial
                Investors,  shall  have the right to select a total of one legal
                counsel to represent the  Investors and an investment  banker or
                bankers  and manager or managers  to  administer  the  offering,
                which investment  banker or bankers or manager or managers shall
                be  reasonably  satisfactory  to the  Company.  In the event the
                Company  determines such banker or manager to be unsatisfactory,
                the Company shall bear the  difference,  if any, in costs of the
                banker  or  manager   ultimately   accepted  and  such  rejected
                underwriter or manager.

                        c. Payments by the Company.  The Company shall cause the
                registration   statement   to  become   effective   as  soon  as
                practicable  after  filing,  but in no event  later than the one
                hundred  twentieth  (120th) day  following the Closing Date (the
                "REGISTRATION  DEADLINE").  If (i) the registration statement(s)
                covering the Registrable  Securities required to be filed by the
                Company   pursuant  to  Section  2(a)  hereof  is  not  declared
                effective by the SEC on or before the  Registration  Deadline or
                if, after the registration statement has been declared effective
                by the  SEC,  sales of  Registrable  Securities  (including  any
                Registrable  Securities  required to be  registered  pursuant to
                Section  3(b)  hereof)  are  not   permitted   pursuant  to  the
                registration  statement  (including by reason of a stop order or
                the Company's  failure to update the registration  statement) or
                (ii) the Common Stock is not listed or included for quotation on
                the NASDAQ  SmallCap  Market  ("NASDAQ"),  the  NASDAQ  National
                Market (the "NNM"),  the New York Stock Exchange (the "NYSE") or
                the American  Stock  Exchange (the "AMEX") at any time after the
                Registration  Deadline,  then the Company will make  payments to
                the  Investors  in such  amounts  and at such  times as shall be
                determined  pursuant to this Section 2(c) as partial  relief for
                the damages to the  Investors  by reason of any such delay in or
                reduction of their  ability to sell the  Registrable  Securities
                (which  remedy  shall not be  exclusive  of any  other  remedies
                available  at law or in equity).  The Company  shall pay to each
                Investor  an  amount  equal  to the  sum of  (i)  the  aggregate
                principal  amount  of  the  Debentures  held  by  such  Investor
                (including,  without  limitation,   Debentures  that  have  been
                converted  into  Conversion  Shares then held by such  Investor)
                (the "AGGREGATE  PURCHASE  PRICE")  multiplied by two hundredths
                (.02) if the  Registration  Statement  filed pursuant to Section
                2(a) is not declared  effective on or prior to the  Registration
                Deadline  plus (ii) an amount  equal to the  Aggregate  Purchase
                Price  multiplied by two  hundredths  (.02) for each full thirty
                (30) day period  thereafter that the Registration  Statement has
                not been  declared  effective  or that  sales are not  permitted
                pursuant  to  the  Registration  Statement  after  it  has  been
                declared  effective  (including by reason of a stop order or the
                Company's failure to update the registration  statement) or that
                the Common  Stock is not listed or  included  for  quotation  on
                NASDAQ,  the NYSE or AMEX (which  amount  shall not be pro rated
                for periods of less than thirty  (30) days);  PROVIDED,  HOWEVER
                that there  shall be  excluded  from each such period any delays
                which are solely attributable to changes (other than corrections
                of  Company  mistakes  with  respect to  information  previously
                provided  by the  Investors)  required by the  Investors  in the
                Registration  Statement with respect to information  relating to
                the Investors,  including,  without  limitation,  changes to the
                plan of distribution and PROVIDED,  FURTHER,  that the aggregate
                amount payable to any Investor under this Section 2(c) shall not


                                       43
<PAGE>

                exceed ten percent (10%) of such Investor's  Aggregate  Purchase
                Price.  (For  example,  if  the  Registration  Statement  is not
                effective by the  Registration  Deadline,  the Company would pay
                $20,000 for each $1,000,000 of Aggregate  Purchase Price and the
                Company would pay an additional  $20,000 for each  $1,000,000 of
                Aggregate  Purchase Price thereafter for each additional  thirty
                (30) days the  Registration  Statement is not effective (up to a
                maximum  of  $100,000  for each  $1,000,000  Aggregate  Purchase
                Price)).  Such  amounts  shall  be  paid  in  cash  or,  at each
                Investor's  option,  may be convertible into Common Stock at the
                "CONVERSION PRICE" (as defined in the Debentures). Any shares of
                Common Stock  issued upon  conversion  of such amounts  shall be
                Registrable  Securities.  If the Investor desires to convert the
                amounts due hereunder  into  Registrable  Securities it shall so
                notify the Company in writing  within two (2)  business  days of
                the date on which  such  amounts  are first  payable in cash and
                such amounts shall be so convertible  (pursuant to the mechanics
                set forth under Article II of the Debentures),  beginning on the
                last day upon which the cash amount  would  otherwise  be due in
                accordance  with  the  following  sentence.   Payments  of  cash
                pursuant hereto shall be made within five (5) days after the end
                of each period that gives rise to such obligation.

                        d. Eligibility for Form S-3. The Company  represents and
                warrants that it meets the  requirements for the use of Form S-3
                for  registration  of the sale by the Initial  Investors and any
                other  Investor of the  Registrable  Securities  and the Company
                shall file all reports  required to be filed by the Company with
                the SEC in a timely  manner so as to maintain  such  eligibility
                for the use of Form S-3.

                3.   OBLIGATIONS  OF  THE  COMPANY.   In  connection   with  the
        registration of the Registrable  Securities,  the Company shall have the
        following obligations:

                        a. The Company shall prepare  promptly and file with the
                SEC the  Registration  Statement  required by Section 2(a),  and
                cause  such  Registration   Statement  relating  to  Registrable
                Securities to become effective as soon as practicable after such
                filing,  but in no event later than the  Registration  Deadline,
                and keep the Registration  Statement  effective pursuant to Rule
                415 at all times  until  such date as is the  earlier of (i) the
                date on which all of the  Registrable  Securities have been sold
                and (ii) the date on which all  Registrable  Securities  (in the
                reasonable  opinion of counsel to the Initial  Investors) may be
                immediately   sold  by  the  Investors  to  the  public  without
                registration   (including,   in  accordance   with  Rule  144(k)
                promulgated   under  the  Securities  Act)  (the   "Registration
                Period"), which Registration Statement (including any amendments
                or supplements  thereto and prospectuses  contained  therein and
                all  documents  incorporated  by  reference  therein)  shall not
                contain any untrue statement of a material fact or omit to state
                a material fact required to be stated  therein,  or necessary to
                make the statements therein not misleading.

                        b. The Company  shall prepare and file with the SEC such
                additional   Registration   Statements   and   such   amendments
                (including  post-effective  amendments)  and  supplements to any
                Registration  Statement  and the  prospectus  used in connection
                with the Registration  Statement as may be necessary to keep the
                Registration   Statement  or  Statements  effective  as  to  all
                Registrable  Securities  at all times  during  the  Registration
                Period,  and, during such period,  comply with the provisions of
                the  Securities  Act  with  respect  to the  disposition  of all
                Registrable   Securities   of  the   Company   covered   by  the
                Registration  Statement or Statements  until such time as all of
                such Registrable  Securities have been disposed of in accordance
                with the  intended  methods  of  disposition  by the  seller  or
                sellers thereof as set forth in the Registration  Statement.  In
                the event an Investor  notifies  the Company  that the number of
                shares available (including, if permissible, shares available by
                reason  of  Rule  416  under  the   Securities   Act)   under  a
                Registration Statement filed pursuant to this Agreement was, for
                any three (3)  consecutive  trading  days (the date the Investor
                notifies the Company of such occurrence being the  "REGISTRATION
                TRIGGER  DATE"),  insufficient to cover a number of shares equal
                to the  applicable  Registration  Percentage  (as defined below)
                multiplied  by all  of  the  Registrable  Securities  issued  or
                issuable upon conversion of the Debentures held by such Investor
                (without   giving  effect  to  any   limitations  on  conversion
                contained in Article II.C of the Debentures),  the Company shall
                amend the  Registration  Statement,  or file a new  Registration
                Statement (on the short form available therefor, if applicable),
                or both, so as to cover one hundred fifty percent  (150%) of the
                Registrable  Securities  issued  or  issuable  to such  Investor
                (without   giving  effect  to  any   limitations  on  conversion
                contained in Article II.C of the  Debentures),  in each case, as
                soon as  practicable,  but in any event within fifteen (15) days
                after the  Registration  Trigger Date (based on the market price
                of the  Common  Stock and other  relevant  factors  on which the
                Company reasonably elects to rely). The Company shall cause such
                amendment and/or new Registration  Statement to become effective
                as soon as  practicable  following  the filing  thereof.  In the
                event the Company fails to obtain the  effectiveness of any such
                Registration   Statement   within   ninety  (90)  days  after  a
                Registration  Trigger Date, each Investor shall  thereafter have
                the option, exercisable in whole or in part at any time and from
                time to time by delivery  of a written  notice to the Company (a

                "REGISTRATION   TRIGGER  PREPAYMENT  NOTICE"),  to  require  the
                Company to pay a portion of such Investor's  Outstanding  Amount
                (as defined in Article I of the Debentures), such that the total
                number of shares of Common Stock  issuable to such Investor upon
                conversion  of its  Debentures  (without  giving  effect  to any
                limitations  on  conversion  contained  in  Article  II.C of the
                Debentures) does not exceed the number of shares then registered
                under an effective  Registration  Statement.  If the Corporation
                fails to pay any portion of such Outstanding  Amount within five
                (5) business  days after its receipt of a  Registration  Trigger
                Prepayment Notice, then such failure shall be deemed a Mandatory
                Prepayment Event as defined in the Debentures,  and the Investor
                shall be entitled to the remedies provided in Article V.B of the
                Debentures. As used herein,  "REGISTRATION PERCENTAGE" means one
                hundred  percent  (100%) for the period  ending on the 150th day
                following the Closing Date and means one hundred and thirty-five
                percent (135%) thereafter.

                        c. The  Company  shall  furnish to each  Investor  whose
                Registrable   Securities   are  included  in  the   Registration
                Statement and its legal  counsel (i) promptly  after the same is
                prepared  and  publicly  distributed,  filed  with the  SEC,  or
                received by the Company, one copy of the Registration  Statement
                and any  amendment  thereto,  each  preliminary  prospectus  and
                prospectus and each amendment or supplement  thereto and, in the
                case of the Registration  Statement referred to in Section 2(a),
                to counsel to the Investors  only,  each letter written by or on
                behalf of the  Company  to the SEC or the staff of the SEC,  and
                each  item of  correspondence  from the SEC or the  staff of the
                SEC, in each case relating to such Registration Statement (other
                than the portion, if any, thereof which contains information for
                which the Company has sought  confidential  treatment)  and (ii)
                such number of copies of a  prospectus,  including a preliminary
                prospectus,  and all amendments and supplements thereto and such
                other documents as such Investor may reasonably request in order
                to facilitate  the  disposition  of the  Registrable  Securities
                owned by such Investor.

                        d. The  Company  shall  use  reasonable  efforts  to (i)
                register and qualify the Registrable  Securities  covered by the
                Registration Statement under such other securities or "blue sky"
                laws of such jurisdictions in the United States as each Investor
                who  holds  Registrable   Securities  being  offered  reasonably
                requests,  (ii)  prepare  and file in those  jurisdictions  such
                amendments (including post-effective amendments) and supplements
                to such  registrations and qualifications as may be necessary to
                maintain  the  effectiveness  thereof  during  the  Registration
                Period,  (iii) take such other  actions as may be  necessary  to
                maintain such  registrations and qualifications in effect at all
                times during the  Registration  Period,  and (iv) take all other
                actions  reasonably   necessary  or  advisable  to  qualify  the
                Registrable Securities for sale in such jurisdictions; PROVIDED,
                HOWEVER,  that the Company  shall not be required in  connection
                therewith  or  as a  condition  thereto  to  (a)  qualify  to do
                business in any  jurisdiction  where it would not  otherwise  be
                required  to qualify  but for this  Section  3(d),  (b)  subject
                itself to general taxation in any such jurisdiction,  (c) file a
                general consent to service of process in any such  jurisdiction,
                (d)  provide  any  undertakings  that  cause the  Company  undue
                expense  or  burden,  or (e) make any  change in its  charter or
                bylaws, which in each case the Board of Directors of the Company
                determines  to be contrary to the best  interests of the Company
                and its stockholders.

                        e. In the event the  Investors  who hold a  majority  in
                interest  of the  Registrable  Securities  being  offered  in an
                offering select underwriters for the offering, the Company shall
                enter into and perform  its  obligations  under an  underwriting
                agreement,  in usual  and  customary  form,  including,  without
                limitation,    customary    indemnification   and   contribution
                obligations, with the underwriters of such offering.

                        f. As promptly as  practicable  after  becoming aware of
                such  event,  the  Company  shall  notify  each  Investor of the
                happening of any event, of which the Company has knowledge, as a
                result  of which the  prospectus  included  in the  Registration
                Statement,  as then in effect, includes an untrue statement of a
                material  fact or omission to state a material  fact required to
                be stated  therein or necessary to make the  statements  therein
                not misleading,  and use its best efforts  promptly to prepare a
                supplement or amendment to the Registration Statement to correct
                such untrue  statement or  omission,  and deliver such number of
                copies of such  supplement or amendment to each Investor as such
                Investor may reasonably request.

                        g. The Company shall use its best efforts to prevent the
                issuance of any stop order or other  suspension of effectiveness
                of a Registration Statement, and, if such an order is issued, to
                obtain the withdrawal of such order at the earliest  practicable
                moment  and  to  notify  each  Investor  who  holds  Registrable
                Securities  being  sold  (or,  in the  event of an  underwritten
                offering,  the  managing  underwriters)  of the issuance of such
                order and the resolution thereof.

                        h. The  Company  shall  permit a single  firm of counsel
                designated by the Initial  Investors to review the  Registration
                Statement,  all  amendments  and  supplements  thereto  and  all
                written  responses  by the  Company  to the  SEC  regarding  the
                Registration   Statement   which  relate  to  the   Investors  a
                reasonable  period of time (and in no event  less than three (3)
                business  days) prior to their filing with the SEC, and not file
                any document in a form to which such counsel reasonably objects.
                In the event such counsel  fails to convey to the Company all of
                its comments  (or that it has no comments) to such  Registration
                Statement   prior  to  the   scheduled   filing   date  of  such
                Registration   Statement  (which  date  shall  comply  with  the
                requirements set forth in this Section 3(h)), the sixty (60) and
                the one  hundred  and twenty  (120) day  periods  referred to in
                Section  2(a)  and 2(c)  shall be  extended  by such  number  of
                business days after such scheduled filing date that such counsel
                so conveys such comments (or that it has no comments).

                        i. The Company  shall make  generally  available  to its
                security holders as soon as practical, but not later than ninety
                (90) days  after the close of the  period  covered  thereby,  an
                earnings  statement (in form  complying  with the  provisions of
                Rule 158 under  the  Securities  Act)  covering  a  twelve-month
                period  beginning  not later than the first day of the Company's
                fiscal   quarter  next  following  the  effective  date  of  the
                Registration  Statement.

                        j. At the request of any Investor,  if the  Registration
                Statement  pertains  to an  underwritten  public  offering,  the
                Company  shall  furnish,  on the  date of  effectiveness  of the
                Registration  Statement  (i) an opinion,  dated as of such date,
                from counsel representing the Company addressed to the Investors
                and in form,  scope and substance as is customarily  given in an
                underwritten public offering and (ii) a letter, dated such date,
                from the Company's  independent  certified public accountants in
                form  and  substance  as is  customarily  given  by  independent
                certified public  accountants to underwriters in an underwritten
                public offering, addressed to the underwriters,  if any, and the
                Investors.

                        k. The Company shall make  available  for  inspection by
                (i) any  Investor,  (ii) any  underwriter  participating  in any
                disposition  pursuant to the Registration  Statement,  (iii) one
                firm of attorneys  and one firm of  accountants  or other agents
                retained  by the  Investors,  and  (iv)  one  firm of  attorneys
                retained   by   all   such   underwriters   (collectively,   the
                "INSPECTORS")  all pertinent  financial and other  records,  and
                pertinent  corporate  documents  and  properties  of the Company
                (collectively,  the  "RECORDS"),  as shall be reasonably  deemed
                necessary by each Inspector to enable each Inspector to exercise
                its  due  diligence  responsibility,  and  cause  the  Company's
                officers,  directors  and  employees  to supply all  information
                which any Inspector may reasonably  request for purposes of such
                due diligence; PROVIDED, HOWEVER, that each Inspector shall hold
                in confidence  and shall not make any  disclosure  (except to an
                Investor) of any Record or other  information  which the Company
                determines  in  good  faith  to be  confidential,  and of  which
                determination  the  Inspectors  are so notified,  unless (a) the
                disclosure  of such  Records is  necessary to avoid or correct a
                misstatement or omission in any Registration Statement,  (b) the
                release of such  Records is ordered  pursuant  to a subpoena  or
                other  order  from a  court  or  government  body  of  competent
                jurisdiction,  or (c) the  information  in such Records has been
                made generally  available to the public other than by disclosure
                in violation of this or any other  agreement.  The Company shall
                not be required to disclose any confidential information in such
                Records to any Inspector  until and unless such Inspector  shall
                have  entered  into  confidentiality  agreements  (in  form  and
                substance  satisfactory  to the  Company)  with the Company with
                respect  thereto,  substantially  as set  forth in this  Section
                3(k).  Each  Investor  agrees that it shall,  upon learning that
                disclosure  of  such  Records  is  sought  in or by a  court  or
                governmental  body of competent  jurisdiction  or through  other
                means,  give prompt notice to the Company and allow the Company,
                at its  expense,  to  undertake  appropriate  action to  prevent
                disclosure of, or to obtain a protective  order for, the Records
                deemed confidential. Nothing herein shall be deemed to limit the
                Investor's  ability to sell  Registrable  Securities in a manner
                which  is  otherwise   consistent   with   applicable  laws  and
                regulations.

                        l. The Company shall hold in confidence and not make any
                disclosure of information concerning an Investor provided to the
                Company unless (i)  disclosure of such  information is necessary
                to  comply  with  federal  or state  securities  laws,  (ii) the
                disclosure of such  information is necessary to avoid or correct
                a misstatement or omission in any Registration Statement,  (iii)
                the  release  of  such  information  is  ordered  pursuant  to a
                subpoena  or other  order from a court or  governmental  body of
                competent  jurisdiction,  (iv)  such  information  has been made
                generally  available to the public other than by  disclosure  in
                violation of this or any other  agreement,  or (v) such Investor
                consents  to the form and  content of any such  disclosure.  The
                Company agrees that it shall,  upon learning that  disclosure of
                such  information  concerning  an  Investor is sought in or by a
                court or governmental body of competent  jurisdiction or through
                other means, give prompt notice to such Investor prior to making
                such  disclosure,  and allow the  Investor,  at its expense,  to
                undertake  appropriate  action to prevent  disclosure  of, or to
                obtain a protective order for, such information.

                        m. The  Company  shall use its best  efforts to promptly
                either (i) cause all the Registrable  Securities  covered by the
                Registration  Statement  to be listed on the NYSE or the AMEX or
                another  national  securities  exchange  and on each  additional
                national  securities  exchange on which  securities  of the same
                class or series  issued by the Company are then listed,  if any,
                if the listing of such Registrable  Securities is then permitted
                under the rules of such exchange, or (ii) secure the designation
                and quotation,  of all the Registrable Securities covered by the
                Registration Statement on the NASDAQ Small Cap Market or the NNM
                and,  without  limiting  the  generality  of the  foregoing,  to
                arrange for or  maintain at least two market  makers to register
                with  the  National  Association  of  Securities  Dealers,  Inc.
                ("NASD") as such with respect to such Registrable Securities.

                        n. The  Company  shall  provide  a  transfer  agent  and
                registrar,  which may be a single  entity,  for the  Registrable
                Securities not later than the effective date of the Registration
                Statement.

                        o. The Company  shall  cooperate  with the Investors who
                hold  Registrable  Securities  being  offered  and the  managing
                underwriter  or  underwriters,  if any, to facilitate the timely
                preparation  and  delivery  of  certificates  (not  bearing  any
                restrictive legends) representing  Registrable  Securities to be
                offered pursuant to the  Registration  Statement and enable such
                certificates to be in such denominations or amounts, as the case
                may be, as the managing underwriter or underwriters,  if any, or
                the  Investors  may  reasonably  request and  registered in such
                names as the managing  underwriter or  underwriters,  if any, or
                the Investors may request,  and,  within three (3) business days
                after  a  Registration   Statement  which  includes  Registrable
                Securities  is ordered  effective by the SEC, the Company  shall
                cause legal counsel  selected by the Company to deliver,  to the
                transfer agent for the  Registrable  Securities  (with copies to
                the Investors whose Registrable  Securities are included in such
                Registration  Statement)  an opinion of such counsel in the form
                attached hereto as EXHIBIT 1.

                        p. At the request of any  Investor,  the  Company  shall
                prepare  and  file  with  the  SEC  such  amendments  (including
                post-effective  amendments)  and  supplements  to a Registration
                Statement  and  the  prospectus  used  in  connection  with  the
                Registration  Statement  as may be  necessary in order to change
                the  plan  of  distribution  set  forth  in  such   Registration
                Statement.

                4.  OBLIGATIONS  OF  THE  INVESTORS.   In  connection  with  the
        registration of the Registrable Securities, the Investors shall have the
        following obligations:

                        a. It shall be a condition  precedent to the obligations
                of the Company to  complete  the  registration  pursuant to this
                Agreement  with  respect  to  the  Registrable  Securities  of a
                particular  Investor  that such  Investor  shall  furnish to the
                Company  such  information  regarding  itself,  the  Registrable
                Securities  held by it and the intended method of disposition of
                the  Registrable  Securities  held by it as shall be  reasonably
                required  to  effect  the   registration  of  such   Registrable
                Securities and shall execute such  documents in connection  with
                such  registration  as the Company may  reasonably  request.  At
                least ten (10)  business  days  prior to the  first  anticipated
                filing date of the  Registration  Statement,  the Company  shall
                notify each Investor in writing of the  information  the Company
                reasonably  requires  from  each  such  Investor  and each  such
                Investor  shall provide such  information no later than five (5)
                business days prior to such anticipated filing date.

                        b. Each Investor,  by such Investor's  acceptance of the
                Registrable Securities,  agrees to cooperate with the Company as
                reasonably  requested  by the  Company  in  connection  with the
                preparation and filing of the Registration  Statement hereunder,
                unless such Investor has notified the Company in writing of such
                Investor's   election   to  exclude   all  of  such   Investor's
                Registrable Securities from the Registration Statement.

                        c.  Each  Investor  whose  Registrable   Securities  are
                included  in  a  Registration  Statement  understands  that  the
                Securities  Act may require  delivery of a  prospectus  relating
                thereto in  connection  with any sale  thereof  pursuant to such
                Registration  Statement and each such  Investor  shall deliver a
                prospectus in connection with any such sale.

                        d. Each Investor agrees to notify the Company  promptly,
                but in any  event  within  72 hours  after the date on which all
                Registrable  Securities,  Debentures  and Common Shares owned by
                such Investor have been sold by such  Investor,  if such date is
                prior to the expiration of the Registration  Period, so that the
                Company  may  comply  with  its   obligation  to  terminate  the
                Registration Statement in accordance with Item 512 of Regulation
                S-K or Regulation S-B, as the case may be.

                        e. In the event Investors holding a majority in interest
                of the Registrable  Securities being offered determine to engage
                the services of an  underwriter,  each Investor  agrees to enter
                into  and  perform   such   Investor's   obligations   under  an
                underwriting  agreement, in usual and customary form, including,
                without limitation,  customary  indemnification and contribution
                obligations,  with the managing underwriter of such offering and
                take such other actions as are  reasonably  required in order to
                expedite  or  facilitate  the  disposition  of  the  Registrable
                Securities,  unless such  Investor  has  notified the Company in
                writing  of such  Investor's  election  to  exclude  all of such
                Investor's   Registrable   Securities   from  the   Registration
                Statement.

                        f. Each Investor agrees that, upon receipt of any notice
                from  the  Company  of the  happening  of any  event of the kind
                described  in  Section  3(f)  or  3(g),   such   Investor   will
                immediately  discontinue  disposition of Registrable  Securities
                pursuant to the Registration Statement covering such Registrable
                Securities  until such  Investor's  receipt of the copies of the
                supplemented or amended prospectus  contemplated by Section 3(f)
                or 3(g) and, if so directed by the Company,  such Investor shall
                deliver  to the  Company  (at the  expense  of the  Company)  or
                destroy   (and   deliver  to  the  Company  a   certificate   of
                destruction)  all copies in such Investor's  possession,  of the
                prospectus  covering such Registrable  Securities current at the
                time of receipt of such notice.

                        g.  No  Investor  may  participate  in any  underwritten
                offering  of  Registrable   Securities   hereunder  unless  such
                Investor  (i)  agrees  to  sell  such   Investor's   Registrable
                Securities   on  the   basis   provided   in  any   underwriting
                arrangements  in usual and  customary  form  entered into by the
                Company, (ii) completes and executes all questionnaires,  powers
                of  attorney,  indemnities,  underwriting  agreements  and other
                documents   reasonably   required   under   the  terms  of  such
                underwriting arrangements,  and (iii) agrees to pay its pro rata
                share of all  underwriting  discounts  and  commissions  and any
                expenses in excess of those  payable by the Company  pursuant to
                Section 5 below.

                5.  EXPENSES  OF  REGISTRATION.  All  expenses  incurred  by the
        Company in  connection  with  registrations,  filings or  qualifications
        pursuant  to  Sections  2 and  3,  including,  without  limitation,  all
        registration,  listing and qualifications  fees, printers and accounting
        fees, the fees and disbursements of counsel for the Company and the fees
        and disbursements  contemplated by Section 3(j) hereof shall be borne by
        the Company.  The Investors  shall be responsible  for any  underwriting
        discounts and commissions  attributable to the Registrable Securities to
        be sold by them and the legal  fees and  disbursements  contemplated  by
        Section 2(b) hereof, except to the extent otherwise set forth in Section
        2(b).

                6. INDEMNIFICATION.  In the event any Registrable Securities are
        included in a Registration Statement under this Agreement:

                        a. To the extent  permitted  by law,  the  Company  will
                indemnify,  hold harmless and defend (i) each Investor who holds
                such Registrable Securities,  and (ii) the directors,  officers,
                partners,   members,  employees,  agents  and  each  person  who
                controls  any  Investor  within the meaning of Section 15 of the
                Securities Act or Section 20 of the  Securities  Exchange Act of
                1934,  as  amended  (the  "EXCHANGE  ACT"),  if any,  (each,  an
                "INDEMNIFIED  PERSON"),  against  any joint or  several  losses,
                claims, damages, liabilities or expenses (collectively, together
                with  actions,  proceedings  or inquiries by any  regulatory  or
                self-regulatory  organization,  whether commenced or threatened,
                in respect  thereof,  "CLAIMS")  to which any of them may become
                subject  insofar as such Claims  arise out of or are based upon:
                (i) any  untrue  statement  or  alleged  untrue  statement  of a
                material  fact in a  Registration  Statement  or the omission or
                alleged omission to state therein a material fact required to be
                stated  or  necessary  to  make  the   statements   therein  not
                misleading,   (ii)  any  untrue   statement  or  alleged  untrue
                statement  of a  material  fact  contained  in  any  preliminary
                prospectus  if  used  prior  to  the  effective   date  of  such
                Registration Statement, or contained in the final prospectus (as
                amended or  supplemented,  if the  Company  files any  amendment
                thereof or  supplement  thereto with the SEC) or the omission or
                alleged omission to state therein any material fact necessary to
                make the statements made therein,  in light of the circumstances
                under which the statements therein were made, not misleading, or
                (iii) any  violation or alleged  violation by the Company of the
                Securities  Act,  the Exchange  Act,  any other law,  including,
                without  limitation,  any state  securities  law, or any rule or
                regulation  thereunder  relating  to the  offer  or  sale of the
                Registrable Securities (the matters in the foregoing clauses (i)
                through (iii) being, collectively, "VIOLATIONS"). Subject to the
                restrictions  set  forth in  Section  6(c) with  respect  to the
                number  of  legal  counsel,  the  Company  shall  reimburse  the
                Investors  and each  such  underwriter  or  controlling  person,


                                       48
<PAGE>

                promptly as such  expenses are incurred and are due and payable,
                for any  reasonable  legal  fees or  other  reasonable  expenses
                incurred by them in connection with  investigating  or defending
                any  such  Claim.   Notwithstanding  anything  to  the  contrary
                contained herein,  the  indemnification  agreement  contained in
                this Section 6(a): (i) shall not apply to a Claim arising out of
                or based upon a Violation  which occurs in reliance  upon and in
                conformity with information  furnished in writing to the Company
                by such Indemnified Person expressly for use in the Registration
                Statement or any such amendment  thereof or supplement  thereto;
                (ii) shall not apply to amounts paid in  settlement of any Claim
                if such settlement is effected without the prior written consent
                of  the  Company,   which  consent  shall  not  be  unreasonably
                withheld; and (iii) with respect to any preliminary  prospectus,
                shall not inure to the benefit of any Indemnified  Person if the
                untrue  statement or omission of material fact  contained in the
                preliminary  prospectus  was  corrected on a timely basis in the
                prospectus,  as then amended or supplemented,  if such corrected
                prospectus was timely made available by the Company  pursuant to
                Section 3(c)  hereof,  and the  Indemnified  Person was promptly
                advised in writing not to use the incorrect  prospectus prior to
                the use giving rise to a Violation and such Indemnified  Person,
                notwithstanding  such  advice,  used it.  Such  indemnity  shall
                remain in full force and effect  regardless of any investigation
                made by or on behalf of the Indemnified Person and shall survive
                the  transfer of the  Registrable  Securities  by the  Investors
                pursuant to Section 9.

                        b. In  connection  with any  Registration  Statement  in
                which an Investor is  participating,  each such Investor  agrees
                severally  and not  jointly  to  indemnify,  hold  harmless  and
                defend,  to the same  extent and in the same manner set forth in
                Section 6(a), the Company,  each of its  directors,  each of its
                officers who signs the  Registration  Statement,  its employees,
                agents and each person,  if any, who controls the Company within
                the meaning of Section 15 of the Securities Act or Section 20 of
                the Exchange Act, and any other stockholder  selling  securities
                pursuant to the  Registration  Statement or any of its directors
                or  officers  or any person who  controls  such  stockholder  or
                underwriter  within  the  meaning of the  Securities  Act or the
                Exchange Act (each an "INDEMNIFIED PARTY"), against any Claim to
                which any of them may become subject,  under the Securities Act,
                the Exchange Act or otherwise,  insofar as such Claim arises out
                of or is based  upon any  Violation,  in each case to the extent
                (and only to the extent) that such Violation  occurs in reliance
                upon and in conformity with written information furnished to the
                Company by such Investor  expressly  for use in connection  with
                such  Registration  Statement;  and subject to Section 6(c) such
                Investor will reimburse any legal or other expenses (promptly as
                such  expenses are incurred and are due and payable)  reasonably
                incurred by them in connection with  investigating  or defending
                any such Claim; PROVIDED,  HOWEVER, that the indemnity agreement
                contained  in this  Section 6(b) shall not apply to amounts paid
                in  settlement  of any  Claim  if such  settlement  is  effected
                without  the  prior  written  consent  of such  Investor,  which
                consent shall not be unreasonably withheld;  PROVIDED,  FURTHER,
                HOWEVER,  that the Investor shall be liable under this Agreement
                (including this Section 6(b) and Section 7) for only that amount
                as does not exceed the net  proceeds  actually  received by such
                Investor  as a  result  of the  sale of  Registrable  Securities
                pursuant to such  Registration  Statement.  Such indemnity shall
                remain in full force and effect  regardless of any investigation
                made by or on behalf of such Indemnified Party and shall survive
                the  transfer of the  Registrable  Securities  by the  Investors
                pursuant to Section 9. Notwithstanding  anything to the contrary
                contained herein,  the  indemnification  agreement  contained in
                this  Section 6(b) with  respect to any  preliminary  prospectus
                shall not inure to the benefit of any  Indemnified  Party if the
                untrue  statement or omission of material fact  contained in the
                preliminary  prospectus  was  corrected on a timely basis in the
                prospectus, as then amended or supplemented, and the Indemnified
                Party failed to utilize such corrected prospectus.

                        c. Promptly  after receipt by an  Indemnified  Person or
                Indemnified  Party  under  this  Section  6  of  notice  of  the
                commencement of any action (including any governmental  action),
                such Indemnified  Person or Indemnified  Party shall, if a Claim
                in respect  thereof is to made  against any  indemnifying  party
                under  this  Section  6,  deliver  to the  indemnifying  party a
                written notice of the commencement thereof, and the indemnifying
                party shall have the right to participate in, and, to the extent
                the  indemnifying  party so  desires,  jointly  with  any  other
                indemnifying party similarly  noticed,  to assume control of the
                defense  thereof  with  counsel  mutually  satisfactory  to  the
                indemnifying party and the Indemnified Person or the Indemnified
                Party,  as  the  case  may  be;  PROVIDED,  HOWEVER,  that  such
                indemnifying  party shall not be entitled to assume such defense
                and an Indemnified  Person or  Indemnified  Party shall have the
                right to retain its own counsel with the fees and expenses to be
                paid by the indemnifying party, if, in the reasonable opinion of
                counsel retained by the indemnifying  party, the  representation
                by such counsel of the Indemnified  Person or Indemnified  Party
                and the indemnifying  party would be inappropriate due to actual
                or  potential  conflicts of interest  between  such  Indemnified
                Person or Indemnified  Party and any other party  represented by
                such  counsel  in such  proceeding  or the  actual or  potential
                defendants  in, or targets of, any such action  include both the
                Indemnified Person or the Indemnified Party and the indemnifying
                party  and any such  Indemnified  Person  or  Indemnified  Party
                reasonably determines that there may be legal defenses available
                to such  Indemnified  Person  or  Indemnified  Party  which  are
                different  from  or in  addition  to  those  available  to  such
                indemnifying  party. The  indemnifying  party shall pay for only
                one separate  legal counsel for the  Indemnified  Persons or the
                Indemnified Parties, as applicable, and such legal counsel shall
                be selected by Investors holding a  majority-in-interest  of the
                Registrable Securities included in the Registration Statement to
                which  the  Claim  relates  (with the  approval  of the  Initial
                Investors if they holds Registrable  Securities included in such
                Registration  Statement),  if  the  Investors  are  entitled  to
                indemnification  hereunder, or by the Company, if the Company is
                entitled  to  indemnification   hereunder,  as  applicable.  The


                                       49
<PAGE>

                failure  to deliver  written  notice to the  indemnifying  party
                within a reasonable time of the  commencement of any such action
                shall not relieve such  indemnifying  party of any  liability to
                the Indemnified  Person or Indemnified  Party under this Section
                6, except to the extent that the indemnifying  party is actually
                prejudiced   in  its   ability  to  defend  such   action.   The
                indemnification  required  by this  Section  6 shall  be made by
                periodic payments of the amount thereof during the course of the
                investigation  or  defense,  as such  expense,  loss,  damage or
                liability is incurred and is due and payable.

                7.  CONTRIBUTION.  To  the  extent  any  indemnification  by  an
        indemnifying  party is  prohibited  or limited by law, the  indemnifying
        party  agrees  to make the  maximum  contribution  with  respect  to any
        amounts for which it would  otherwise be liable  under  Section 6 to the
        fullest  extent  permitted  by  law;  PROVIDED,  HOWEVER,  that  (i)  no
        contribution shall be made under circumstances where the maker would not
        have been liable for indemnification under the fault standards set forth
        in  Section  6, (ii) no person  guilty of  fraudulent  misrepresentation
        (within the  meaning of Section  11(f) of the  Securities  Act) shall be
        entitled to contribution  from any seller of Registrable  Securities who
        was  not  guilty  of  such  fraudulent   misrepresentation,   and  (iii)
        contribution  (together with any  indemnification  or other  obligations
        under this Agreement) by any seller of Registrable  Securities  shall be
        limited in amount to the net amount of proceeds  received by such seller
        from the sale of such Registrable Securities.

                8.  REPORTS  UNDER  THE  EXCHANGE  ACT.  With a view  to  making
        available to the  Investors the benefits of Rule 144  promulgated  under
        the  Securities  Act or any other  similar rule or regulation of the SEC
        that may at any time  permit the  Investors  to sell  securities  of the
        Company to the public  without  registration  ("RULE 144"),  the Company
        agrees to:

                        a.  file  with the SEC in a timely  manner  and make and

                other reports and  documents so filed by the Company,  and (iii)
                such other information as may be reasonably  requested to permit

                9.  ASSIGNMENT  OF  REGISTRATION   RIGHTS.  The  rights  of  the
        Investors  hereunder,  including the right to have the Company  register

        any  portion  of  the  Debentures,  Common  Shares  or  the  Registrable
        Securities if: (i) the Investor agrees in writing with the transferee or

        securities  by the  transferee  or  assignee  is  restricted  under  the
        Securities Act and applicable  state  securities laws, (iv) at or before
        the time the Company receives the written notice  contemplated by clause
        (ii) of this sentence, the transferee or assignee agrees in writing with
        the Company to be bound by all of the provisions  contained herein,  and
        (v) such transfer shall have been made in accordance with the applicable

                11. MISCELLANEOUS.

                instructions,  notice or election  received from the  registered
                owner of such Registrable Securities.

                personally or by courier or by confirmed telecopy,  and shall be
                effective  five days after being placed in the mail,  if mailed,
                or upon receipt or refusal of receipt,  if delivered  personally

                        c.  Failure of any party to exercise any right or remedy
                under  this  Agreement  or  otherwise,  or  delay  by a party in
                exercising  such right or remedy,  shall not operate as a waiver
                thereof.

                        d. This Agreement  shall be governed by and construed in
                accordance with the laws of the State of Delaware  applicable to
                contracts made and to be performed in the State of Delaware. The
                Company  irrevocably  consents to the jurisdiction of the United
                States federal courts located in the County of Kent in the State
                of Delaware in any suit or proceeding  based on or arising under
                this Agreement and irrevocably agrees that all claims in respect
                of such suit or proceeding may be determined in such courts. The
                Company  irrevocably waives the defense of an inconvenient forum
                to the  maintenance  of such  suit or  proceeding.  The  Company
                further agrees that service of process upon the Company,  mailed
                by first class mail shall be deemed in every  respect  effective
                service  of  process  upon  the  Company  in any  such  suit  or
                proceeding.  Nothing herein shall affect the Investors' right to
                serve process in any other manner  permitted by law. The Company
                agrees that a final non-appealable  judgment in any such suit or
                proceeding  shall be  conclusive  and may be  enforced  in other
                jurisdictions  by suit on such  judgment or in any other  lawful
                manner.

                        e. This Agreement and the Securities  Purchase Agreement
                (including  all schedules and exhibits  thereto)  constitute the
                entire  agreement  among the parties  hereto with respect to the
                subject  matter hereof and thereof.  There are no  restrictions,
                promises, warranties or undertakings, other than those set forth
                or  referred  to herein  and  therein.  This  Agreement  and the
                Securities Purchase Agreement supersede all prior agreements and
                understandings  among the  parties  hereto  with  respect to the
                subject matter hereof and thereof.

                        f. Subject to the requirements of Section 9 hereof, this
                Agreement  shall inure to the benefit of and be binding upon the
                successors and assigns of each of the parties hereto.

                        g. The headings in this Agreement are for convenience of
                reference  only and  shall  not limit or  otherwise  affect  the
                meaning hereof.

                        h.  This  Agreement  may be  executed  in  two  or  more
                counterparts,  each of which shall be deemed an original but all
                of  which  shall  constitute  one and the same  agreement.  This
                Agreement,  once  executed by a party,  may be  delivered to the
                other party hereto by facsimile  transmission  of a copy of this
                Agreement  bearing the signature of the party so delivering this
                Agreement.

                        i. Each party shall do and perform,  or cause to be done
                and  performed,  all such  further  acts and  things,  and shall
                execute  and deliver  all such other  agreements,  certificates,
                instruments  and  documents,  as the other party may  reasonably
                request  in order to carry out the  intent  and  accomplish  the
                purposes  of  this  Agreement  and  the   consummation   of  the
                transactions contemplated hereby.

                        j. All consents and other  determinations  to be made by
                the  Investors  or  the  Initial  Investors   pursuant  to  this
                Agreement  shall  be  made  by  the  Investors  or  the  Initial
                Investors  holding  a  majority  of the  Registrable  Securities
                (determined  as if all  Debentures  then  outstanding  had  been
                converted into or exercised for Registrable  Securities) held by
                all Investors or Initial Investors, as the case may be.

                        k. The initial number of Registrable Securities included
                on any Registration Statement and each increase to the number of
                Registrable  Securities  included thereon shall be allocated pro
                rata  among the  Investors  based on the  number of  Registrable
                Securities   held  by  each   Investor   at  the  time  of  such
                establishment  or increase,  as the case may be. In the event an
                Investor  shall sell or otherwise  transfer any of such holder's
                Registrable Securities, each transferee shall be allocated a pro
                rata portion of the number of Registrable Securities included on
                a  Registration  Statement  for such  transferor.  Any shares of
                Common  Stock  included on a  Registration  Statement  and which
                remain allocated to any person or entity which does not hold any
                Registrable  Securities  shall  be  allocated  to the  remaining
                Investors, pro rata based on the number of shares of Registrable
                Securities then held by such Investors.

RE:      PALOMAR MEDICAL TECHNOLOGIES, INC.

Dear Mr. Lemmer:

We are counsel to PALOMAR MEDICAL  TECHNOLOGIES,  INC., a corporation  organized
under the laws of the State of Delaware (the "COMPANY"),  and we understand that
[Name of Investor]  (the "HOLDER") has purchased from the Company (i) 6%, 7% and
8%  Convertible  Debentures Due September 30, 2002 (the  "DEBENTURES")  that are
convertible  into shares of the Company's Common Stock, par value $.01 per share
(the "COMMON STOCK") and (ii) shares of Common Stock (the "COMMON SHARES").  The
Debentures  and  Common  Shares  were  purchased  by the  Holder  pursuant  to a
Securities Purchase Agreement,  dated as of September 30, 1997, by and among the
Company  and  the  signatories   thereto  (the   "AGREEMENT").   Pursuant  to  a
Registration Rights Agreement,  dated as of September 30, 1997, by and among the
Company and the signatories thereto (the "REGISTRATION  RIGHTS AGREEMENT"),  the
Company agreed with the Holder,  among other things, to register the Registrable
Securities (as that term is defined in the Registration  Rights Agreement) under
the Securities Act of 1933, as amended (the  "SECURITIES  ACT"),  upon the terms
provided in the Registration Rights Agreement.  In connection with the Company's
obligations  under the Registration  Rights  Agreement,  on ________,  1997, the
Company   filed  a   Registration   Statement  on  Form  S-___  (File  No.  333-
_____________)  (the "REGISTRATION  STATEMENT") with the Securities and Exchange
Commission (the "SEC") relating to the Registrable  Securities,  which names the
Holder as a selling stockholder thereunder.

[Customary introductory and scope of examination language to be inserted]

Based on the foregoing,  we are of the opinion that the  Registrable  Securities
have been registered under the Securities Act.

         [Other customary language to be included.]

Very truly yours,


cc:   [Name of Investor]

        2. PURCHASERS' REPRESENTATIONS AND WARRANTIES

        Each Purchaser severally represents and warrants to the Company that:

                a.  Investment  Purpose.  Purchaser is purchasing the Debentures
        and Common Shares for  Purchaser's  own account for investment  only and
        not with a present view towards the public sale or distribution thereof,
        except  pursuant  to  sales  that  are  exempt  from  the   registration
        requirements  of the  Securities Act and/or sales  registered  under the
        Securities  Act.  Purchaser  understands  that  Purchaser  must bear the
        economic risk of this investment indefinitely, unless the Securities are
        registered  pursuant  to the  Securities  Act and any  applicable  state
        securities or blue sky laws or an exemption  from such  registration  is
        available,  and that the Company has no present intention of registering
        any such  Securities  other  than as  contemplated  by the  Registration
        Rights Agreement.  Notwithstanding  anything in this Section 2(a) to the
        contrary,  by making the representations  herein, the Purchaser does not
        agree to hold the  Securities for any minimum or other specific term and
        reserves  the  right  to  dispose  of  the  Securities  at any  time  in
        accordance with or pursuant to a registration  statement or an exemption
        under the Securities Act.

                b.  Accredited  Investor  Status.  Purchaser  is an  "Accredited
        Investor"  as defined in Rule 501(a)  promulgated  under the  Securities
        Act.

                c.  Reliance  on  Exemptions.  Purchaser  understands  that  the
        Debentures  and Common Shares are being offered and sold to Purchaser in
        reliance upon specific exemptions from the registration  requirements of
        United States federal and state  securities laws and that the Company is
        relying upon the truth and accuracy of, and Purchaser's compliance with,
        the  representations,   warranties,   agreements,   acknowledgments  and
        understandings  of Purchaser  set forth herein in order to determine the
        availability  of such  exemptions  and the  eligibility  of Purchaser to
        acquire the Debentures and Common Shares.

                d. Information.  Purchaser and its counsel or representative, if
        any,  have  been  furnished  all  materials  relating  to the  business,
        finances and  operations  of the Company and  materials  relating to the
        offer and sale of the  Debentures  and  Common  Shares  which  have been
        specifically  requested by  Purchaser or its counsel or  representative.
        Purchaser and its counsel, if any, have been afforded the opportunity to
        ask questions of the Company and have received what  Purchaser  believes
        to be complete and satisfactory  answers to any such inquiries.  Neither
        such  inquiries nor any other due diligence  investigation  conducted by
        Purchaser  or its counsel or any of its  representatives  shall  modify,
        amend  or   affect   Purchaser's   right   to  rely  on  the   Company's
        representations and warranties  contained in Section 3 below.  Purchaser
        understands  that  Purchaser's  investment in the Securities  involves a
        high degree of risk.

                e.  Governmental  Review.  Purchaser  understands that no United
        States federal or state agency or any other  government or  governmental
        agency has passed upon or made any  recommendation or endorsement of the
        Securities.

                f. Transfer or Resale.  Purchaser understands that (i) except as
        provided in the Registration  Rights Agreement,  the Securities have not
        been and are not being  registered under the Securities Act or any state
        securities  laws,  and may not be  transferred  unless (a)  subsequently
        registered  thereunder,  or (b)  Purchaser  shall have  delivered to the
        Company an opinion of counsel (which opinion shall be in form, substance
        and scope customary for opinions of counsel in comparable  transactions)
        to the effect that the Securities to be sold or transferred  may be sold
        or  transferred   pursuant  to  an  exemption  from  such  registration,
        including  without  limitation Rule 144 promulgated under the Securities
        Act (or a successor  rule)  ("RULE  144"),  or (c)  transferred  without
        consideration  to an  affiliate  of  Purchaser;  (ii)  any  sale of such
        Securities  made in reliance on Rule 144 may be made only in  accordance
        with the terms of said Rule and further, if said Rule is not applicable,
        any resale of such Securities  under  circumstances  in which the seller
        (or the  person  through  whom the sale is made)  may be deemed to be an
        underwriter  (as that term is defined in the Securities Act) may require
        compliance  with some other  exemption  under the  Securities Act or the
        rules and  regulations of the Securities  and Exchange  Commission  (the
        "SEC") thereunder; and (iii) neither the Company nor any other person is
        under any  obligation to register such  Securities  under the Securities
        Act or any  state  securities  laws or to  comply  with  the  terms  and
        conditions  of any  exemption  thereunder  (in  each  case,  other  than
        pursuant to the Registration Rights Agreement).

                                       55
<PAGE>

                g. Legends. Purchaser understands that the Debentures and Common
        Shares  and,  until  such  time  as  the  Conversion  Shares  have  been
        registered  under the Securities Act as contemplated by the Registration
        Rights Agreement or otherwise may be sold by Purchaser  pursuant to Rule
        144  without  any  restriction  as to the  public  resale  thereof,  the
        certificates for the Conversion Shares may bear a restrictive  legend in
        substantially  the  following  form  (and a  stop-transfer  order may be
        placed against transfer of the certificates for such Securities):

                The  securities  represented by this  certificate  have not been
                registered  under the  Securities  Act of 1933, as amended.  The
                securities  have been  acquired  for  investment  and may not be
                sold,  transferred  or assigned  in the absence of an  effective
                registration  statement for the securities under said Act, or an
                opinion of counsel,  in form,  substance and scope customary for
                opinions   of   counsel   in   comparable   transactions,   that
                registration  is not  required  under  said  Act or  unless  the
                Company  is  provided  with   reasonable   assurances  that  the
                securities were sold pursuant to Rule 144 under said Act.

                The legend set forth  above  shall be  removed  and the  Company
        shall issue a  certificate  without such legend upon  conversion  of the
        Debentures  to the holder of any Security  upon which it is stamped,  if
        (a) the resale of such Security is registered  under the Securities Act,
        or (b) such holder  provides the Company with an opinion of counsel,  in
        form,   substance  and  scope  customary  for  opinions  of  counsel  in
        comparable transactions, to the effect that a public sale or transfer of
        such Security may be made without  registration under the Securities Act
        or (c) such holder provides the Company with reasonable  assurances that
        such Security has been sold pursuant to Rule 144 or can be sold pursuant
        to Rule 144  without  any  restriction  as to the  number of  Securities
        acquired  as of a  particular  date that can then be  immediately  sold.
        Purchaser agrees to sell all Securities,  including those represented by
        a certificate(s) from which the legend has been removed,  pursuant to an
        effective   registration  statement  and  to  deliver  a  prospectus  in
        connection  with  such  sale  (if and to the  extent  such  delivery  is
        required)  or in  compliance  with an  exemption  from the  registration
        requirements  of the  Securities  Act. In the event the above  legend is
        removed  from  any  Security  and  thereafter  the  effectiveness  of  a
        registration  statement  covering  such  Security  is  suspended  or the
        Company determines that a supplement or amendment thereto is required by
        applicable  securities  laws,  then upon  reasonable  advance  notice to
        Purchaser the Company may require that the above legend be placed on any
        such  Security  that  cannot  then  be  sold  pursuant  to an  effective
        registration  statement  or Rule 144 without any  restriction  as to the
        number of Securities  acquired as of a particular  date that can then be
        immediately  sold,  which legend shall be removed when such Security has
        been sold  pursuant to Rule 144 or may be sold  pursuant to an effective
        registration  statement  or Rule 144 without any  restriction  as to the
        number of Securities  acquired as of a particular  date that can then be
        immediately sold.

                h.   Authorization;   Enforcement.   This   Agreement   and  the
        Registration  Rights  Agreement  have been duly and validly  authorized,
        executed and  delivered on behalf of Purchaser and are valid and binding
        agreements of Purchaser  enforceable in accordance with their respective
        terms.

                i. Location of Purchaser. Each of the Purchasers has advised the
        Company  in  writing  with  respect  to the  jurisdictions  wherein  the
        investment decision regarding Purchaser's  acquisition of the Debentures
        and the Common Shares has been made.

        3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

        The Company represents and warrants to each Purchaser that:

                a. Organization and  Qualification.  The Company and each of its
        subsidiaries  is a  corporation  duly  organized  and  existing  in good
        standing under the laws of the jurisdiction in which it is incorporated,
        and has the requisite corporate power to own its properties and to carry
        on its  business  as now being  conducted.  The  Company and each of its
        subsidiaries  is duly qualified as a foreign  corporation to do business
        and is in good  standing in every  jurisdiction  where the failure so to
        qualify would have a Material Adverse Effect.  "MATERIAL ADVERSE EFFECT"
        means  any  material  adverse  effect  on  the  operations,  properties,
        condition  (financial  or otherwise) or prospects of the Company and its
        subsidiaries, taken as a whole on a consolidated basis or on the ability
        of the  Company  to  perform  its  obligations  in  connection  with the
        transactions contemplated hereby on a timely basis. The Company does not
        have any significant subsidiaries (as defined in Rule 1-02 of Regulation
        S-X under the Securities Act) other than those subsidiaries set forth on
        Schedule 3(a).

                b. Authorization; Enforcement. (i) The Company has the requisite
        corporate  power and authority to enter into and perform this  Agreement
        and the Registration Rights Agreement,  to issue and sell the Debentures
        and Common Shares in accordance with the terms hereof,  and to issue the
        Conversion  Shares upon  conversion of the Debentures in accordance with
        their  terms;  (ii) the  execution,  delivery  and  performance  of this
        Agreement,  the Registration  Rights Agreement and the Debentures by the
        Company  and the  consummation  by it of the  transactions  contemplated
        hereby and thereby  (including  without  limitation  the issuance of the
        Debentures  and  Common  Shares and the  issuance  and  reservation  for
        issuance of the  Conversion  Shares)  have been duly  authorized  by the
        Company's Board of Directors and no further consent or  authorization of
        the Company,  its Board or Directors,  or its  stockholders  is required
        (under Rules  promulgated  by the  National  Association  of  Securities
        Dealers or  otherwise);  (iii) this Agreement has been duly executed and
        delivered by the Company; and (iv) this Agreement constitutes, and, upon
        execution  and  delivery  by  the  Company  of the  Registration  Rights
        Agreement and the  Debentures,  such agreement and such  instrument will
        constitute,  valid and binding  obligations  of the Company  enforceable
        against the Company in accordance with their respective terms.

                c.  Capitalization.  The capitalization of the Company as of the
        date hereof,  including  the  authorized  capital  stock,  the number of
        shares  issued  and  outstanding,  the  number  of shares  reserved  for
        issuance  pursuant to the Company's  stock option  plans,  the number of
        shares  reserved for  issuance  pursuant to  securities  (other than the
        Debentures) exercisable for, or convertible into or exchangeable for any
        shares of  Common  Stock and the  number  of shares to be  reserved  for
        issuance  upon  conversion  of the  Debentures  is set forth on Schedule
        3(c). All of such outstanding shares of capital stock have been, or upon
        issuance  will be,  validly  issued,  fully paid and  nonassessable.  No
        shares of capital stock of the Company  (including the  Debentures,  the
        Common  Shares and the  Conversion  Shares)  are  subject to  preemptive
        rights or any other similar rights of the stockholders of the Company or
        any liens or  encumbrances.  Except as disclosed in Schedule  3(c) or as
        contemplated herein, as of the date of this Agreement,  (i) there are no
        outstanding options,  warrants,  scrip, rights to subscribe to, calls or
        commitments  of any character  whatsoever  relating to, or securities or
        rights  convertible into or exercisable or exchangeable  for, any shares
        of  capital  stock  of  the  Company  or any  of  its  subsidiaries,  or
        arrangements  by which the Company or any of its  subsidiaries is or may
        become bound to issue additional  shares of capital stock of the Company
        or any  of its  subsidiaries,  and  (ii)  there  are  no  agreements  or
        arrangements  under  which the  Company  or any of its  subsidiaries  is
        obligated to register the sale of any of the Company's  securities under
        the  Securities  Act (except the  Registration  Rights  Agreement).  The
        Company has made  available to each Purchaser true and correct copies of
        the  Company's  Certificate  of  Incorporation  as in effect on the date
        hereof  ("CERTIFICATE OF  INCORPORATION"),  the Company's  By-laws as in
        effect on the date hereof (the "BY-LAWS"), and all other instruments and
        agreements  governing  securities  convertible  into or  exercisable  or
        exchangeable for Common Stock of the Company.  The Company shall provide
        each Purchaser with a written  update of this  representation  signed by
        the Company's  Chief  Executive  Officer or Chief  Financial  Officer on
        behalf of the Company as of the Closing Date.

                d. Issuance of Securities.  The  Debentures are duly  authorized
        and, upon issuance in accordance with the terms of this Agreement,  will
        be  validly  issued  and  free  from  all  taxes,   liens,   claims  and
        encumbrances  and will not be  subject  to  preemptive  rights  or other
        similar  rights of  stockholders  of the Company.  The Common Shares are
        duly  authorized and, upon issuance in accordance with the terms of this
        Agreement,  will be validly issued,  fully paid and non-assessable,  and
        free from all  taxes,  liens,  claims and  encumbrances  and will not be
        subject to preemptive  rights or other similar rights of stockholders of
        the Company.  The Conversion Shares are duly authorized and reserved for
        issuance,  and, upon conversion of the Debentures in accordance with the
        terms thereof,  will be validly issued,  fully paid and  non-assessable,
        and free from all taxes,  liens, claims and encumbrances and will not be
        subject to preemptive  rights or other similar rights of stockholders of
        the Company.

                e. No Conflicts. The execution, delivery and performance of this
        Agreement,  the Registration  Rights Agreement and the Debentures by the
        Company, the performance by the Company of its obligations hereunder and
        thereunder,  and the  consummation  by the  Company of the  transactions
        contemplated  hereby and thereby  (including,  without  limitation,  the
        issuance and reservation for issuance, as applicable,  of the Debentures
        and Common  Shares and the  Conversion  Shares) will not (i) result in a
        violation  of the  Certificate  of  Incorporation  or  By-laws  or  (ii)
        conflict with, or constitute a default (or an event which with notice or
        lapse of time or both would become a default)  under,  or give to others
        any rights of termination,  amendment,  acceleration or cancellation of,
        any  agreement,  indenture or  instrument to which the Company or any of
        its  subsidiaries is a party, or result in a violation of any law, rule,
        regulation,  order, judgment or decree (including U.S. federal and state
        securities laws and regulations) applicable to the Company or any of its
        subsidiaries  or by which any property or asset of the Company or any of
        its  subsidiaries  is  bound or  affected  (except  for such  conflicts,


                                       57
<PAGE>

        defaults,  terminations,  amendments,  accelerations,  cancellations and
        violations  as would  not,  individually  or in the  aggregate,  have or
        reasonably be expected to result in a Material Adverse Effect).  Neither
        the  Company  nor  any  of  its  subsidiaries  is in  violation  of  its
        Certificate  of  Incorporation  or other  organizational  documents  and
        neither the Company nor any of its  subsidiaries  is in default  (and no
        event has occurred  which,  with notice or lapse of time or both,  would
        put the Company or any of its  subsidiaries in default)  under,  nor has
        there  occurred any event giving others (with notice or lapse of time or
        both) any rights of termination, amendment, acceleration or cancellation
        of, any  agreement,  indenture or instrument to which the Company or any
        of its subsidiaries is a party,  except for possible  defaults or rights
        as would not,  individually  or in the aggregate,  have or reasonably be
        expected to result in a Material  Adverse Effect.  The businesses of the
        Company and its subsidiaries  are not being conducted,  and shall not be
        conducted  so  long  as a  Purchaser  owns  any  of the  Securities,  in
        violation  of any  law,  ordinance  or  regulation  of any  governmental
        entity,  except for possible  violations  the sanctions for which either
        singly or in the  aggregate  would not have or reasonably be expected to
        result in a Material Adverse Effect. Except as specifically contemplated
        by this  Agreement  and  except  for  the  filing  of a Form D with  the
        Securities  and  Exchange  Commission,  the  filing of the  registration
        statement  contemplated by the  Registration  Rights Agreement under the
        Securities Act, any filings required by applicable state securities laws
        and the filing of an application  with NASDAQ (as defined below) to list
        or approve for quotation the  Conversion  Shares and the Common  Shares,
        the Company is not  required  to obtain any  consent,  authorization  or
        order  of,  or make  any  filing  or  registration  with,  any  court or
        governmental agency or any regulatory or self regulatory agency in order
        for it to execute,  deliver or perform any of its obligations under this
        Agreement, the Registration Rights Agreement or the Debentures,  in each
        case in accordance with the terms hereof or thereof.  The Company is not
        in violation of the listing  requirements  of the NASDAQ SmallCap Market
        ("NASDAQ") and does not reasonably  anticipate  (nor has it received any
        notices  to such  effect  from  NASDAQ)  that the  Common  Stock will be
        delisted by NASDAQ in the foreseeable future.

                f. SEC Documents, Financial Statements. Since December 31, 1993,
        the Company has timely filed all reports,  schedules,  forms, statements
        and other documents  required to be filed by it with the SEC pursuant to
        the reporting  requirements  of the Securities  Exchange Act of 1934, as
        amended (the "EXCHANGE  ACT") (all of the foregoing,  filed prior to the
        date hereof and after  December  31,  1993,  and all  exhibits  included
        therein and financial  statements  and  schedules  thereto and documents
        (other than exhibits)  incorporated by reference  therein  together with
        any  registration  statements  or other  documents  filed by the Company
        pursuant  to the  Securities  Act  prior to the date  hereof  and  those
        certain  news  releases   attached   hereto  as  Schedule  3(f),   being
        hereinafter referred to herein as the "SEC DOCUMENTS").  The Company has
        made  available to each  Purchaser  true and complete  copies of the SEC
        Documents,   except  for  such  exhibits,   schedules  and  incorporated
        documents.  As of their respective dates, the SEC Documents  complied in
        all material  respects with the  requirements of the Exchange Act or the
        Securities Act, as the case may be, and the rules and regulations of the
        SEC promulgated thereunder applicable to the SEC Documents,  and none of
        the SEC Documents,  at the time they were filed with the SEC,  contained
        any untrue  statement of a material  fact or omitted to state a material
        fact  required to be stated  therein or  necessary  in order to make the
        statements  therein, in light of the circumstances under which they were
        made,  not  misleading.  As of their  respective  dates,  the  financial
        statements of the Company included in the SEC Documents  complied in all
        material  respects  with  applicable  accounting  requirements  and  the
        published  rules and regulations of the SEC with respect  thereto.  Such
        financial   statements  have  been  prepared  in  accordance  with  U.S.
        generally accepted accounting principles,  consistently applied,  during
        the periods involved  (except (i) as may be otherwise  indicated in such
        financial  statements  or the  notes  thereto,  or (ii)  in the  case of
        unaudited interim  statements,  to the extent they may include footnotes
        or may not be condensed or summary statements) and fairly present in all
        material respects the consolidated financial position of the Company and
        its   consolidated   subsidiaries  as  of  the  dates  thereof  and  the
        consolidated  results of their operations and cash flows for the periods
        then ended  (subject,  in the case of  unaudited  statements,  to normal
        year-end  audit  adjustments).  Except  as set  forth  in the  financial
        statements of the Company included in the SEC Documents, the Company has
        no  liabilities,  contingent  or otherwise,  other than (i)  liabilities
        incurred in the ordinary  course of business  subsequent  to the date of
        the most recent financial  statements  included in the SEC Documents and
        (ii)  obligations  under  contracts  and  commitments  incurred  in  the
        ordinary  course of business and not required under  generally  accepted
        accounting  principles  to be  reflected in such  financial  statements,
        which,  individually  or in  the  aggregate,  are  not  material  to the
        financial condition or operating results of the Company.

                g.  Absence  of  Litigation.  Except  as  disclosed  in the  SEC
        Documents or in Schedule  3(g),  there is no action,  suit,  proceeding,
        inquiry  or  investigation   before  or  by  any  court,  public  board,
        government agency,  self-regulatory  organization or body pending or, to
        the  knowledge  of the  Company or any of its  subsidiaries,  threatened
        against or affecting  the Company,  any of its  subsidiaries,  or any of
        their  respective  directors  or officers in their  capacities  as such,
        wherein  an  unfavorable  decision,  ruling  or  finding  would or could
        reasonably be expected to result in a Material Adverse Effect.

                h.  Disclosure.  All  information  relating to or concerning the
        Company  set  forth in this  Agreement  or  provided  to the  Purchasers
        pursuant to Section  2(d) hereof and  otherwise in  connection  with the
        transactions  contemplated  hereby is true and  correct in all  material
        respects  and the  Company has not  omitted to state any  material  fact
        necessary  in order to make the  statements  made herein or therein,  in
        light of the  circumstances  under which they were made, not misleading.
        No event or  circumstance  has  occurred or exists  with  respect to the
        Company or its subsidiaries or their respective businesses,  properties,
        prospects,  operations or financial conditions,  which, under applicable
        law, rule or regulation,  requires public  disclosure or announcement by
        the Company but which has not been so publicly  announced  or  disclosed
        (assuming for this purpose that the  Company's  Exchange Act Reports are
        being incorporated into an effective registration statement filed by the
        Company under the Securities Act).

                i. Current Public Information. The Company is currently eligible
        to register the resale of its Common Stock on a  registration  statement
        on Form S-3 under the Securities Act.

                j. No General  Solicitation.  Neither the Company nor any person
        acting for the Company has conducted any "GENERAL SOLICITATION," as such
        term is defined in Regulation  D, with respect to any of the  Securities
        being offered hereby.

                k. No Integrated  Offering.  Neither the Company, nor any of its
        affiliates,  nor any person acting on its or their behalf,  has directly
        or indirectly  made any offers or sales of any security or solicited any
        offers  to buy any  security  under  circumstances  that  would  require
        registration of the Securities being offered hereby under the Securities
        Act.

                l. No Brokers.  The Company has taken no action which would give
        rise to any claim by any person for brokerage commissions, finder's fees
        or similar  payments by any Purchaser  relating to this Agreement or the
        transactions  contemplated  hereby,  except for  dealings  with  Michael
        Arnouse whose commissions and fees will be paid for by the Company.

                m.  Acknowledgment of Dilution.  The number of Conversion Shares
        issuable upon conversion of the Debentures may increase substantially in
        certain  circumstances,  including the circumstance  wherein the trading
        price of the Common Stock declines.  The Company  acknowledges  that its
        obligation to issue Conversion  Shares upon conversion of the Debentures
        in accordance with their terms is absolute and unconditional, regardless
        of the dilution that such  issuance may have on the ownership  interests
        of other stockholders.

                n.   Intellectual   Property.   Each  of  the  Company  and  its
        subsidiaries  owns or possesses  adequate and enforceable  rights to use
        all patents,  patent applications,  trademarks,  trademark applications,
        trade  names,  service  marks,   copyrights,   copyright   applications,
        licenses,  know-how (including trade secrets and other unpatented and/or
        unpatentable  proprietary  or  confidential   information,   systems  or
        procedures)   and  other  similar  rights  and   proprietary   knowledge
        (collectively,  "INTANGIBLES") necessary for the conduct of its business
        as now being  conducted and as described in the Company's  Annual Report
        on Form 10-KSB for the fiscal year ended  December 31, 1996, as amended.
        Neither the Company nor any subsidiary of the Company infringes or is in
        conflict  with  any  right  of any  other  person  with  respect  to any
        Intangibles which,  individually or in the aggregate,  if the subject of
        an  unfavorable  decision,  ruling  or  finding,  would  have  or  could
        reasonably be expected to result in a Material Adverse Effect.

                o. Foreign Corrupt  Practices.  Neither the Company,  nor any of
        its subsidiaries,  nor any director,  officer,  agent, employee or other
        person  acting on behalf of the  Company or any  subsidiary  has, in the
        course of acting for, or on behalf of, the Company,  used any  corporate
        funds  for any  unlawful  contribution,  gift,  entertainment  or  other
        unlawful  expenses  relating to political  activity;  made any direct or
        indirect unlawful payment to any foreign or domestic government official
        or employee  from  corporate  funds;  violated or is in violation of any
        provision of the U.S. Foreign Corrupt Practices Act of 1977; or made any
        bribe,  rebate,  payoff,  influence payment,  kickback or other unlawful
        payment to any foreign or domestic government official or employee.

        of Common Stock  issuable upon  conversion of the  Debentures  upon each
        national securities exchange or automated quotation system, if any, upon
        which shares of Common Stock are then listed (subject to official notice
        of issuance) and thereafter shall maintain,  so long as any other shares
        of Common Stock shall be so listed,  such  listing of all Common  Shares
        and all Conversion  Shares from time to time issuable upon conversion of
        the  Debentures.  The Company  shall also file such  additional  listing
        applications  as may be  necessary  to cover the  issuance of all of the

        NASDAQ National Market ("NNM"),  the New York Stock Exchange ("NYSE") or

        with the Company's  reporting,  filing and other  obligations  under the

        ("NASD") and such exchanges, as applicable.

                h. Corporate Existence. So long as a Purchaser beneficially owns
        any  Debentures,  the Company shall  maintain its  corporate  existence,
        except  in the  event  of a  merger,  consolidation  or  sale  of all or
        substantially  all of the Company's  assets, as long as the surviving or
        successor   entity  in  such   transaction  (i)  assumes  the  Company's
        obligations  hereunder and under the agreements and instruments  entered
        into in  connection  herewith  regardless  of whether or not the Company
        would have had a sufficient  number of shares of Common Stock authorized
        and  available  for  issuance in order to effect the  conversion  of all
        Debentures  outstanding as of the date of such transaction and (ii) is a
        publicly traded  corporation whose common stock is listed for trading on
        the NASDAQ, NNM, NYSE or AMEX.

        5. TRANSFER AGENT INSTRUCTIONS.

        The Company  shall  instruct its transfer  agent to issue  certificates,
registered  in the name of each  Purchaser  or its nominee,  for the  Conversion
Shares in such amounts as specified  from time to time by such  Purchaser to the
Company  upon  conversion  of  the  Debentures.  Prior  to  registration  of the
Conversion  Shares under the Securities Act or resale of such  Securities  under
Rule 144, all such certificates  shall bear the restrictive  legend specified in
Section 2(g) of this Agreement.  The Company warrants that no instruction  other
than  such  instructions  referred  to in this  Section  5,  and  stop  transfer
instructions to give effect to Section 2(f) hereof in the case of the Conversion
Shares prior to registration of the Conversion  Shares under the Securities Act,
will be given by the Company to its transfer agent and that the Securities shall
otherwise be freely  transferable on the books and records of the Company as and
to the extent provided in this Agreement,  the Registration Rights Agreement and

                                       60

the Debentures. Nothing in this Section shall affect in any way each Purchaser's
obligations  and  agreement  set forth in Section  2(f) hereof not to resell the
Securities  except  pursuant  to an  effective  registration  statement  (and to
deliver a prospectus  in connection  with such a sale) or in compliance  with an
exemption from the registration  requirements of applicable securities law. If a
Purchaser  provides  the Company  with an opinion of counsel,  which  opinion of
counsel shall be in form,  substance and scope customary for opinions of counsel
in  comparable  transactions,  to the effect that the  Securities  to be sold or
transferred   may  be  sold  or  transferred   pursuant  to  an  exemption  from
registration,  the Company  shall permit the  transfer,  and, in the case of the
Conversion  Shares,  promptly  instruct its transfer  agent to issue one or more
certificates in such name and in such denominations as specified by a Purchaser.
The Company  acknowledges that a breach by it of its obligations  hereunder will
cause irreparable harm to a Purchaser by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly,  the Company acknowledges that the
remedy  at law for a breach  of its  obligations  under  this  Section 5 will be
inadequate  and  agrees,  in the event of a breach or  threatened  breach by the
Company of the provisions of this Section 5, that a Purchaser shall be entitled,
in addition to all other available  remedies,  to an injunction  restraining any
breach and requiring  immediate issuance and transfer,  without the necessity of
showing economic loss and without any bond or other security being required.

        unenforceability  shall not affect the validity or enforceability of the
        remainder of this  Agreement or the validity or  enforceability  of this
        Agreement in any other jurisdiction.
