    Image Guided Technologies, Inc. (the "Company") is hereby offering 1,200,000
shares (the "Shares") of common stock, no par value (the "Common Stock").
    
 
   
    Prior to  this offering,  there has  been no  public market  for the  Common
Stock,  and there  can be no  assurance that  any such market  will develop upon
completion of this offering. It is currently anticipated that the initial public
offering price will  be $5.00 per  Share. The  Company has applied  to have  the
Common  Stock quoted on the Nasdaq SmallCap-TM- Market under the proposed symbol
"IGTI" and to have the  Common Stock traded on  the Boston Stock Exchange  under
the  proposed  symbol "IGK."  For  a description  of  the factors  considered in
determining the initial public offering price, see "Underwriting."
    
 
   
    THE COMMON STOCK OFFERED  HEREBY INVOLVES A HIGH  DEGREE OF RISK. SEE  "RISK
FACTORS"  BEGINNING ON PAGE 6 FOR A DISCUSSION OF CERTAIN MATTERS THAT SHOULD BE
CONSIDERED BY PROSPECTIVE INVESTORS.
    
                             ---------------------
 
THESE SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES  AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE COMMISSION
  OR  ANY STATE SECURITIES COMMISSION PASSED  UPON THE ACCURACY OR ADEQUACY OF
  THIS                                PROSPECTUS. ANY REPRESENTATION TO  THE
                        CONTRARY IS A CRIMINAL OFFENSE.

RECAPITALIZATION."
    
 
                                  THE COMPANY
 
   
    Image   Guided  Technologies,   Inc.  (the   "Company")  designs,  develops,
manufactures  and   markets   products  for   real-time,   precise,   free-hand,
localization  of points in three dimensional ("3D") space. The Company's optical
localizers, typically  consisting  of  a  number  of  custom-manufactured  light
emitting  diodes ("LEDs") mounted on a device  or instrument to be tracked in 3D
space, a relative position  dynamic reference device  connected to the  measured
object,  a multi-camera  array for  detecting the  LED emissions,  a proprietary
microprocessor-based control system  and proprietary software  to calculate  the
digital  coordinate  location  of the  LEDs,  have both  medical  and industrial
applications. The Company manufactures its FlashPoint localizer for medical uses
and its Pixsys localizer for industrial uses.
    
 
   
        MEDICAL APPLICATIONS.    The Company's  FlashPoint  localizer is  a  key
    component  of the anatomical image display workstation used by physicians to
    perform image  guided  surgery,  a  specialty  procedure  in  the  field  of
    minimally  invasive surgery. When the  FlashPoint localizer is combined with
    the imaging  software provided  by  the Company's  customers, such  as  Carl
    Zeiss,  Inc.  ("Zeiss"), GE  Medical  Systems ("GEMS"),  Surgical Navigation
    Technologies,  Inc./Sofamor  Danek   Group  ("SNT/Sofamor  Danek"),   DeeMed
    International   ("DeeMed")   and  Radionics   Software   Applications,  Inc.
    ("Radionics"), all  of  which  use the  Company's  FlashPoint  product,  the
    location  of  specially  designed  surgical instruments  can  be  tracked in
    relation to the patient's anatomy  during surgical procedures by display  as
    an overlay on medical images (such as magnetic resonance imaging ("MRI") and
    computerized  tomography ("CT")). The  Company believes that  the ability of
    the surgeon to track  the relative location  of specially designed  surgical
    instruments  on the  image display workstation  can result  in less invasive
    procedures  that  lead  to  shorter  hospital  stays  and  improved  patient
    outcomes.
    
 
        INDUSTRIAL  APPLICATIONS.   The  Company's Pixsys  localizer is  used in
    various industrial applications to measure the position or shape of  objects
    in   3D   space.  Illustrative   uses   include  inspection   of   parts  by
    Harley-Davidson, Inc., detection of surface deformities in car bodies during
    manufacture by Daimler-Benz and as a  3D navigation aid in its  zero-gravity
    chamber  by the United  States National Aeronautic  and Space Administration
    ("NASA").
 
    The Company's business strategy is to systematically enhance the performance
of its optical  localizers while expanding  the market for  such products.  With
respect  to  enhancing its  products,  the Company  is  seeking to  increase the
products' accuracy, enlarge the field-of-view,  increase the sample/ frame  rate
(throughput)  and improve the customer computer interface. With regard to market
expansion,  the   Company  is   seeking  to   identify  additional   measurement
applications for its products.
 
   
    The Company was founded in 1986 and was incorporated in Colorado in February
1990.  The Company's place  of business is at  5710-B Flatiron Parkway, Boulder,
Colorado 80301, and its telephone number is (303) 447-0248.
    
 
   
    Flashpoint-Registered Trademark-, Dynamic Reference
Frame-Registered Trademark- and Pixsys-TM- are trademarks of the Company.

                         SUMMARY FINANCIAL INFORMATION
 
    The following summary  financial information should  be read in  conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations"  and  the  Company's  Financial  Statements  and  the  Notes thereto
included elsewhere in this Prospectus. The statement of operations data for  the
years  ended December 31, 1994 and 1995,  and the balance sheet data at December
31, 1995,  are  derived  from, and  should  be  read in  conjunction  with,  the
Company's Financial Statements and the Notes thereto audited by Price Waterhouse
LLP,  independent  accountants,  included  elsewhere  in  this  Prospectus.  The
statement of operations data for the six  month periods ended June 30, 1995  and
1996,  and  the balance  sheet data  at June  30, 1996,  have been  derived from
unaudited  interim  financial  statements  and   include,  in  the  opinion   of
management,  all adjustments  (consisting only of  normal recurring adjustments)
necessary to present  fairly the  results of  operations for  such periods.  The
operating  results for the  six months ended  June 30, 1996  are not necessarily
indicative of the results to be expected for the full year or any future period.

                                  RISK FACTORS
 
    AN INVESTMENT IN THE SHARES OFFERED HEREBY IS HIGHLY SPECULATIVE, INVOLVES A
HIGH DEGREE OF RISK AND SHOULD BE MADE ONLY BY INVESTORS WHO CAN AFFORD THE LOSS
OF THEIR ENTIRE INVESTMENT. PROSPECTIVE INVESTORS, PRIOR TO MAKING AN INVESTMENT
DECISION, SHOULD CAREFULLY CONSIDER, TOGETHER WITH THE OTHER MATTERS REFERRED TO
HEREIN,  INCLUDING  THE FINANCIAL  STATEMENTS AND  THE  NOTES THERETO,  THE RISK
FACTORS SET FORTH BELOW:
 
   
    LIMITED  HISTORY  OF  PROFITABILITY;  POTENTIAL  FLUCTUATIONS  IN  OPERATING
RESULTS.   The  Company has experienced  significant operating  losses since its
inception, had an  accumulated deficit of  $3,380,855 at December  31, 1995  and
$3,255,021  at  June 30,  1996  and had  a net  tangible  book value  deficit of
$603,672 at December 31, 1995 and $140,338  at June 30, 1996. While the  Company
has  been profitable during the six months ended  June 30, 1996, there can be no
assurance that  the Company  will ever  generate sufficient  revenues to  attain
profitability  on an  annual basis. In  addition, because  the Company generally
ships its products  on the basis  of purchase orders,  operating results in  any
quarter  are highly dependent on orders booked  and shipped in that quarter and,
accordingly, may fluctuate  materially from  quarter to  quarter. The  Company's
operating expense levels are based on the Company's internal forecasts of future
demand  and not on firm customer orders. Failure by the Company to achieve these
internal forecasts could result  in expense levels  which are inconsistent  with
actual  revenues, which  could have a  material adverse effect  on the Company's
business, financial condition and results of operations. Moreover, the Company's
quarterly results may also be affected  by fluctuating demand for the  Company's
products,  declines  in the  average  selling prices  for  its products,  and by
increases in  the costs  of the  components and  subassemblies acquired  by  the
Company  from vendors.  See "Management's  Discussion and  Analysis of Financial
Condition and Results of Operations."
    
 
   
    DEPENDENCE ON A  SINGLE TYPE  OF PRODUCT.   All the  Company's revenues  are
derived  from sales of its optical localizers. Although the Company is currently
seeking to expand the markets for its localizers, there can be no assurance that
it will be successful. Unless the Company can expand its product line or develop
additional applications for its products, the Company will be subject to all the
risks inherent  in a  single  product enterprise,  including increased  risk  of
technological   obsolescence.   See   "Risk   Factors--Uncertainty   of   Market
Acceptance."
    
 
   
    UNCERTAINTY OF MARKET  ACCEPTANCE.   The market for  optical localizers  has
only  recently  commenced  to  develop.  The  Company's  largest  medical device
customers, Zeiss and  SNT/Sofamor Danek,  began commercial sale  of their  image
guided  surgery products in 1996. If the  market for optical localizers fails to
continue to  develop,  develops more  slowly  than the  Company  anticipates  or
ceases,  the Company's business,  financial condition and  results of operations
would be materially and adversely affected. Demand for optical localizers  could
be  affected by numerous factors outside the Company's control, including, among
others, market  acceptance  by  medical and  industrial  customers,  changes  in
governmental  regulation  and  the  introduction of  new  or  superior competing
technologies. See "Business."
    
 
    RAPID TECHNOLOGICAL CHANGE.  The  market for localizers is characterized  by
rapid  and significant technological change. There  can be no assurance that the
Company's competitors will not  succeed in developing  or marketing products  or
technologies  that are  more effective and/or  less costly and  which render the
Company's products obsolete  or non-competitive. In  addition, new  technologies
and  procedures could be developed for medical and other industries that replace
or reduce the value of the Company's products. The Company's success will depend
in part on its ability to  respond quickly to technological changes through  the
development  and  improvement  of  its products.  Accordingly,  the  Company has
estimated that approximately $1,000,000 (20.8%) of the estimated net proceeds of
this offering, assuming  an initial public  offering price of  $5.00 per  Share,
will  be allocated to fund further  research and development activities, and the
Company believes that  a substantial amount  of capital will  be required to  be
allocated  to such activities in the future.  There can be no assurance that the
Company's product development  efforts will  be successful. The  failure by  the
Company to improve its
 
                                       6
<PAGE>
existing  products and develop new products could have a material adverse effect
on the Company's business,  financial condition and  results of operations.  See
"Business--Research and Development" and "Business--Competition."
 
   
    CUSTOMER CONCENTRATION; PATENTS ON SYSTEMS THAT UTILIZE LOCALIZERS.  For the
year  ended December 31, 1995 and the six  months ended June 30, 1996, the three
largest customers of  the Company collectively  accounted for approximately  70%
and  88%, respectively,  of the  revenues of  the Company.  The loss  of, or the
substantial diminution of purchases from the Company by, any of these  customers
could have a material adverse effect on the Company. None of these customers has
entered  into  any  long-term  minimum  purchase  agreements  with  the Company.
Accordingly, purchases from the  Company by such customers  in any prior  period
may  not be indicative  of orders or  purchases in any  future period. See "Risk
Factors--Uncertainty of Market  Acceptance," "Risk Factors--Rapid  Technological
Change,"  "Management's  Discussion  and  Analysis  of  Financial  Condition and
Results of Operations," "Business--Customers and Use" and "Business--Backlog."
    
 
   
    There are a  number of patents  that utilize  a localizer as  part of  their
claimed  inventions, several of which relate to the medical industry. One of the
patents relating  to the  medical industry  is  a patent  granted to  St.  Louis
University  on January 24, 1995 (the "SLU Patent"), and subsequently licensed to
Surgical Navigation  Technologies,  Inc. ("SNT"),  one  of the  Company's  major
customers.  In  general,  the  SLU  Patent  covers  a  particular  technique for
determining the  position of  a surgical  probe within  a patient's  body on  an
historical  image of  that body. The  Company is  not in a  position to evaluate
whether its customers  may be  infringing the  SLU Patent  or any  of the  other
patents.  If any infringement claim is brought  or threatened against any of the
Company's customers, it could  have a material adverse  effect on orders of  the
Company's products from these customers. See "Business--Intellectual Property."
    
 
   
    ABSENCE  OF  PATENT  PROTECTION.   The  Company  does not  have  any patents
covering its  FlashPoint or  Pixsys  optical localizers.  The Company  has  been
issued  one U.S.  patent (which  may cover  future products)  and has  four U.S.
patent applications pending (three of which, if granted, relate to current  uses
of  the Company's product and  the other of which,  if granted, may cover future
products). The Company  primarily relies on  a combination of  trade secret  and
copyright  laws, together with nondisclosure  agreements to protect its know-how
and proprietary  rights. There  can  be no  assurance  that such  measures  will
provide adequate protection for the Company's intellectual property rights, that
disputes  with respect to the ownership of its intellectual property rights will
not arise, that the Company's trade  secrets or proprietary technology will  not
otherwise  become known or be independently developed by competitors or that the
Company can  otherwise meaningfully  protect its  intellectual property  rights.
Furthermore,  there can  be no  assurance that  others will  not develop similar
products or software, duplicate the Company's products or software or that third
parties will not  assert intellectual property  infringement claims against  the
Company.  The Company believes  that the manufacture and  sale of its FlashPoint
localizer does  not  infringe  the SLU  Patent,  since  a localizer  is  only  a
component  part in the system patented by SLU and since the Company's FlashPoint
localizer has  substantial  non-infringing  uses.  Moreover,  there  can  be  no
assurance  that  any  patent  owned  by the  Company  will  not  be invalidated,
circumvented or  challenged, that  the rights  granted thereunder  will  provide
meaningful  competitive advantages to  the Company or that  any of the Company's
pending or future patent applications will be issued. The failure of the Company
to protect its proprietary  rights could have a  material adverse effect on  its
business,    financial    condition    and    results    of    operations.   See
"Business--Intellectual Property."
    
 
   
    Litigation may be necessary to  protect the Company's intellectual  property
rights and trade secrets, to determine the validity and scope of the proprietary
rights  of  others or  to defend  against claims  of infringement  or invalidity
(including, without limitation, claims brought by parties whose technology, such
as that which may be  the basis of the SLU  Patent, utilizes a localizer).  Such
litigation could also result in substantial costs and diversion of resources and
could  have  a  material adverse  effect  on the  Company's  business, financial
condition  and  results  of   operations.  There  can   be  no  assurance   that
infringement,  invalidity, right to use or  ownership claims by third parties or
claims for
    
 
                                       7
<PAGE>
indemnification resulting from infringement claims  will not be asserted in  the
future.  If any claims or actions are  asserted against the Company, the Company
may be required to obtain a license under a third party's intellectual  property
rights.  There can be no assurance, however, that a license will be available to
the Company  on reasonable  terms or  at all.  In addition,  should the  Company
determine  to  litigate  such  claims,  such  litigation  could  also  result in
substantial costs and diversion of resources and could materially and  adversely
affect  the Company's business,  financial condition and  results of operations,
regardless  of  the  outcome  of  the  litigation.  See  "Business--Intellectual
Property."
 
   
    COMPETITION.   The Company believes it is  currently a leader in the sale of
optical localizers to the  medical market. The  Company's primary competitor  in
the  medical market  currently is Northern  Digital, Inc.  ("NDI"). In addition,
companies  with   substantially   greater   financial,   technical,   marketing,
manufacturing and human resources, as well as name recognition, than the Company
may  also enter the market.  Competitors may be able  to respond more quickly to
new or emerging technologies and changes in customer requirements and to  devote
substantially  greater resources to the development, marketing and sale of their
products than  the Company.  The Company's  customers may  determine to  develop
their  own localizers to  ensure control over their  localizer technology or for
other reasons. Furthermore, such competitors  may develop technology other  than
that  based on  infrared optics  that is more  effective or  economical than the
technology of the Company  in localizing a  point in space.  Any failure by  the
Company to develop products that compete favorably in the marketplace would have
a  material adverse  effect on the  Company's business,  financial condition and
results of operations. See "Business--Competition."
    
 
    POSSIBLE NEED FOR ADDITIONAL  FINANCING.  Based  on the Company's  operating
plan, the Company believes that the net proceeds of this offering, together with
funds  from operations, will  be sufficient to  satisfy its capital requirements
and finance its plans for expansion for at least the next 18 months. Such belief
is based  on  certain assumptions,  and  there can  be  no assurance  that  such
assumptions  are correct. In addition,  contingencies or opportunities may arise
which would require the Company to obtain additional capital. Accordingly, there
can be  no assurance  that such  resources  will be  sufficient to  satisfy  the
Company's  capital requirements for such period. After such 18-month period, the
Company may require additional  financing. Such financing may  take the form  of
the  issuance of common  or preferred stock  or debt securities,  or may involve
bank financing. There  can be  no assurance  that the  Company will  be able  to
obtain such additional capital on a timely basis, on favorable terms or at all.
 
   
    GOVERNMENT  REGULATION.  The Company's  FlashPoint localizer is incorporated
by the Company's customers  into medical devices that  are subject to  extensive
regulation by the United States Food and Drug Administration (the "FDA") and, in
some instances, by foreign and state governments. The FDA regulates the clinical
testing,  manufacture,  labeling, sale,  distribution  and promotion  of medical
devices. Before a new device can be introduced into the market, the manufacturer
must obtain market  clearance through either  the 510(k) premarket  notification
process  or the lengthier and more costly premarket approval ("PMA") application
process. Noncompliance with applicable requirements  can result in, among  other
things,  fines,  injunctions, civil  penalties, recall  or seizure  of products,
total or partial suspension  of production, failure of  the government to  grant
premarket  clearance or premarket approval  for devices, withdrawal of marketing
approvals and criminal prosecution.  The FDA also has  the authority to  request
repair, replacement or refund of the cost of any device.
    
 
   
    The  Company  believes that  the FlashPoint  localizer  is a  medical device
component not subject to the full panoply of the FDA medical device regulations,
including the market clearance requirements. The medical equipment manufacturers
that incorporate  the FlashPoint  localizer into  their products  are,  however,
required   to  obtain  market   clearance  from  the   FDA  for  such  products.
Modifications  to   such  products   manufactured  by   the  medical   equipment
manufacturers   will  require  additional  clearances   or  approvals,  if  such
modifications could significantly  affect the  safety and  effectiveness of  the
devices  or  establish a  new  intended use  for the  devices.  There can  be no
assurance that the Company's customers have  complied or will be able to  comply
with all applicable market clearance requirements.
    
 
                                       8
<PAGE>
Failure  on the part of the Company's customers to comply with such requirements
could have  a  material adverse  effect  on the  Company's  business,  financial
condition and results of operations. See "Business--Government Regulation."
 
    There  can be  no assurance  that the  FDA will  not require,  or change its
interpretations or regulations so  as to require, the  Company to obtain  510(k)
clearance  for its FlashPoint localizer apart from  or in addition to any market
clearances obtained by its medical device  customers. Failure of the Company  to
comply  with such  market clearance requirements  could have  a material adverse
affect on the Company's business, financial condition and results of operations.
See "Business--Government Regulation."
 
    Products manufactured by the Company  and its medical device customers  that
incorporate  the Company's products are subject  to continuing regulation by the
FDA. FDA enforcement policy strictly prohibits the promotion of products for any
uses other  than  those  for  which clearance  or  approval  was  obtained.  The
Company's  manufacturing facilities  and those  of its  medical device customers
that incorporate its  products may also  be subject to  periodic inspection  for
compliance  with  good  manufacturing  practices  ("GMP")  and  other regulatory
requirements  by  the   FDA  and   comparable  state   agencies.  In   addition,
international  sales  of  medical  devices  are  subject  to  foreign regulatory
requirements, which  vary  from country  to  country. Violations  of  regulatory
requirements  of the FDA or  foreign or state regulatory  agencies or changes in
such regulations or interpretations of  such regulations, could have a  material
adverse  affect on  the Company's business,  financial condition  and results of
operations. See "Business--Government Regulation."
 
    HEALTH CARE  REFORM.   The health  care industry  is undergoing  fundamental
changes  as a  result of political,  economic and regulatory  influences. In the
United States, comprehensive programs have  been proposed that seek to  increase
access  to health care for the uninsured,  control the escalation of health care
expenditures within the economy  and use health  care reimbursement policies  to
help  control the  federal deficit.  The Company  anticipates that  Congress and
state legislatures will continue  to review and  assess alternative health  care
delivery  systems and methods of payment and  public debate of these issues will
likely  continue.  Due  to  uncertainties   regarding  the  outcome  of   reform
initiatives  and their enactment and  implementation, the Company cannot predict
which, if any, of such  reform proposals will be adopted  or when they might  be
adopted.  Other countries are  also considering health  care reform. Significant
changes in health care systems could have a substantial impact on the manner  in
which the Company conducts its business and could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
   
    DEPENDENCE  ON KEY PERSONNEL.  The  Company's success depends in significant
part on  the continued  contribution  of certain  key management  and  technical
personnel,  including: Paul  L. Ray, Chairman  of the Board  and Chief Executive
Officer of  the Company;  Robert  E. Silligman,  President and  Chief  Operating
Officer of the Company; Waldean Schulz, Vice President, Technology and Secretary
of  the  Company;  and Jeffrey  J.  Hiller,  Vice President,  Finance  and Chief
Financial Officer of the Company. Although the Company has employment  contracts
with  all  four of  these individuals  through  December 31,  1998, the  loss of
services of any of these individuals could have a material adverse effect on the
Company. The Company  has applied  for key man  life insurance  policies in  the
amount  of $1,000,000  on the lives  of each of  Mr. Ray and  Mr. Silligman. The
Company's growth and  profitability also depend  on its ability  to attract  and
retain other management and technical personnel. See "Management."
    
 
    RISK  OF PRODUCT LIABILITY  CLAIMS.  The Company  faces an inherent business
risk of exposure to product  liability claims in the event  that the use of  its
products  is alleged to  have resulted in  adverse effects. To  date, no product
liability claims have been asserted against the Company. The Company maintains a
product  liability  and  commercial  general  liability  insurance  policy  with
coverage  of $1,000,000 per occurrence and  an annual aggregate maximum coverage
of $2,000,000 ($1,000,000  for lawsuits  outside the United  States, Canada  and
Puerto  Rico). The Company's  product liability and  general liability policy is
provided on an  occurrence basis  and is subject  to annual  renewal. There  can

be  no assurance that  liability claims will  not exceed the  coverage limits of
such policy or that such insurance will continue to be available on commercially
reasonable terms  or  at  all.  If  the Company  does  not  or  cannot  maintain
sufficient  liability insurance,  its ability  to market  its products  could be
significantly impaired. See "Business--Product Liability Insurance."
 
   
    IMMEDIATE AND SUBSTANTIAL DILUTION.   The initial  public offering price  is
substantially  higher than the Company's negative  $0.08 per share pro forma net
tangible book  value at  June 30,  1996. Investors  purchasing the  Shares  will
therefore  incur immediate, substantial dilution of  at least $3.38 per share of
Common Stock (at an assumed initial public offering price of $5.00 per Share and
after underwriting  discounts and  estimated offering  expenses payable  by  the
Company).  To the extent that outstanding stock options and warrants to purchase
shares of  Common  Stock are  exercised,  there  may be  further  dilution.  See
"Dilution."
    
 
   
    ARBITRARY  OFFERING PRICE.  The public offering price of the Shares has been
determined by negotiation between the Company and the Representative and may not
be indicative of the price at which  the Shares will trade after the  completion
of  the offering. Among the factors considered  in such negotiations were (i) an
assessment of  the  Company's  future  prospects, (ii)  the  experience  of  the
Company's  management, (iii) the current financial position of the Company, (iv)
the prevailing conditions in the securities markets, including the market  value
of  the publicly traded common stock of companies in similar industries, (v) the
market conditions  for new  offerings  of securities  and  (vi) the  demand  for
similar securities of comparable companies. See "Underwriting."
    
 
    NO  PRIOR MARKET FOR  THE COMMON STOCK.   Prior to  this offering, there has
been no public market for the Common  Stock, and there can be no assurance  that
an active trading market therefore will develop or, if any such market develops,
that  it  will be  sustained. Accordingly,  purchasers of  the Common  Stock may
experience difficulty selling or otherwise  disposing of their shares of  Common
Stock.
 
    DIVIDENDS.  The Company has not paid any dividends on the Common Stock since
inception  and does not intend  to pay any dividends  to its shareholders in the
foreseeable future. The Company currently intends to reinvest earnings, if  any,
in  the development  and expansion  of its  business. See  "Dividend Policy" and
"Description of Securities--Common Stock."
 
   
    SHARES ELIGIBLE FOR FUTURE SALE.  The  sale, or availability for sale, of  a
substantial  number of shares of Common Stock in the public market subsequent to
this offering pursuant  to Rule  144 under the  Securities Act  ("Rule 144")  or
otherwise could materially adversely affect the market price of the Common Stock
and  could impair the Company's ability  to raise additional capital through the
sale of its equity securities or debt financing. The availability of Rule 144 to
the holders of  restricted securities of  the Company would  be conditioned  on,
among  other things, the  availability of certain  public information concerning
the Company. All of the 1,667,741 shares of Common Stock outstanding immediately
prior to the closing of this  offering are "restricted securities" as that  term
is  defined in Rule  144 and may,  under certain circumstances,  be sold without
registration under  the Securities  Act. Ordinarily,  any shares  issuable  upon
exercise  of options, pursuant  to Rule 701  under the Securities  Act, could be
sold publicly commencing 90 days after  the Company becomes a reporting  Company
under  the Securities  Exchange Act  of 1934,  as amended  (the "Exchange Act").
However, the Representive is requiring holders of all of the outstanding  shares
of  Common Stock to  agree not to sell  or otherwise dispose  of their shares of
Common Stock for a period of 18 months from the date of this Prospectus  without
the Representative's prior written consent.
    
 
   
    The  holders of the  Representative's Warrants will  have certain demand and
"piggy back" registration rights with respect to such warrants and the shares of
Common Stock underlying such warrants (the "Warrant Shares") commencing one year
after the date hereof.  If the Representative  should exercise its  registration
rights  to effect a distribution of the Representative's Warrants or the Warrant
Shares, the  Representative, prior  to  and during  such distribution,  will  be
unable  to make  a market  in the Company's  securities, which  may therefore be
limited. If the Representative ceases making  a market in the Common Stock,  the
Company    could    lose    the    ability   to    list    the    Common   Stock
    
 
                                       10

on the Nasdaq SmallCap Market because  of such market's requirement of at  least
two  market makers,  the market and  market prices  for the Common  Stock may be
materially adversely affected,  and holders  thereof may  be unable  to sell  or
otherwise  dispose of  shares of Common  Stock. See "Shares  Eligible For Future
Sale" and "Underwriting."
    
 
   
    SUBSTANTIAL OPTIONS AND  WARRANTS RESERVED; CONTINGENT  ISSUANCES OF  COMMON
STOCK.   The Company  has reserved 640,000  shares of Common  Stock for issuance
pursuant to the Plan. To date options to purchase an aggregate of 620,397 shares
of Common Stock have been granted pursuant to the Plan and warrants to  purchase
an  additional  40,000  shares of  Common  Stock are  outstanding,  although the
Representative is requiring the holders of  all of such options and warrants  to
agree  not to  sell any shares  of Common  Stock issuable upon  exercise of such
options and warrants for a period of 18 months from the date of this  Prospectus
without  the Representative's prior written consent.  The Company will also sell
to  the  Representative   in  connection   with  this   offering,  for   nominal
consideration, the Representative's Warrants to purchase an aggregate of 120,000
shares  of Common Stock at a price per share equal to 110% of the initial public
offering price per share, subject to adjustment as provided therein. The Company
has agreed that, under certain circumstances, it will register under federal and
state securities laws the Representative's  Warrants and/or the Warrant  Shares.
The  existence of the Representative's  Warrants, the outstanding options issued
under the Plan and  such other warrants  may prove to be  a hindrance to  future
financings,  since the holders of  such warrants and options  may be expected to
exercise them at  a time  when the  Company would  otherwise be  able to  obtain
additional   equity  capital  on  terms  more  favorable  to  the  Company.  See
"Management" and "Underwriting-- Representative's Warrants."
    
 
    POSSIBLE VOLATILITY OF STOCK  PRICE.  The market  price of the Common  Stock
may  be highly volatile. Factors such as fluctuations in the Company's operating
results, announcements  of  technological innovations  or  new products  by  the
Company   or  its   competitors,  FDA  and   international  regulatory  actions,
developments with respect to  patents or proprietary  rights, changes in  health
care  policy in  the United States  or internationally, changes  in stock market
analyst  recommendations  regarding   the  Company,   other  companies   selling
components to the medical device industry and general market conditions may have
a  significant effect on the market price  of the Common Stock. In addition, the
stock market has  from time  to time  experienced significant  price and  volume
fluctuations   that  are  unrelated  to   operating  performance  of  particular
companies. These broad market fluctuations may adversely affect the market price
of the Common Stock.
 
   
    PREFERRED STOCK; POSSIBLE ANTI-TAKEOVER EFFECTS.  The Company's Articles  of
Incorporation  authorizes the Board of Directors to issue up to 2,416,668 shares
of preferred stock. 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, among other
things, 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. At  the date hereof, there are outstanding
83,332 shares of Series  A Preferred Stock which  will be mandatorily  converted
into  an aggregate of  304,290 shares of  Common Stock upon  the closing of this
offering. The Company has  no present plans for  the issuance of any  additional
preferred  stock.  However,  the  issuance of  any  such  preferred  stock could
materially  adversely  affect  the  rights  of  holders  of  Common  Stock  and,
therefore,  could reduce  the value of  the Common Stock.  In addition, specific
rights granted to future  holders of preferred stock  could be used to  restrict
the  Company's ability to merge with, or sell  its assets to, a third party. The
ability of the  Board of Directors  to issue preferred  stock could  discourage,
delay  or prevent a takeover  of the Company, thereby  preserving control of the
Company by the current shareholders. See "Description of Securities."

                                USE OF PROCEEDS
 
    The net  proceeds to  the Company  from  the sale  of the  1,200,000  Shares
offered  hereby  are  estimated to  be  approximately  $4,800,000 (approximately
$5,583,000 if the  Underwriters' over-allotment  option is  exercised in  full),
assuming  an initial public  offering price of $5.00  per Share, after deducting
underwriting discounts and commissions  and estimated offering expenses  payable
by  the Company. The Company  presently intends to use  the net proceeds of this
offering as follows:

(1)  The Company intends to repay debt of approximately $883,077, consisting  of
     $775,000  in principal amount of outstanding loans and $108,077 in interest
     accrued through September 30, 1996. These loans were made in 1995 and  used
     for  working capital and  other general corporate  purposes. The loans bear
     interest at the rate of  11% per annum and mature  upon the earlier of  the
     closing  of a public offering with gross proceeds of at least $5,000,000 or
     June 30, 1997. See "Certain Transactions".
    
 
(2)  Includes product  literature costs  and salaries  and associated  costs  of
     additional marketing and technical support personnel.
 
   
(3)  The  balance  of  the  estimated  net proceeds  will  be  used  for general
     corporate and working  capital purposes (including  payment of  outstanding
     payables).  The Company may also utilize a  portion of the proceeds of this
     offering to  acquire or  license  technology or  to acquire  businesses  or
     establish  joint ventures that  are complementary to  the current or future
     business of the Company. While the Company is currently evaluating  various
     possibilities,  it has no agreements, arrangements or undertakings with any
     third party for any acquisitions, licenses or joint ventures. There can  be
     no  assurance  that  any  new  technology  will  be  acquired  or licensed,
     businesses acquired or joint ventures effected or that, if consummated, any
     such  transaction   will  be   successful.  See   "Business--Research   and
     Development."
    
 
    The  foregoing represents the  Company's best estimate  of its allocation of
the net proceeds of the  sale of the Shares  based upon the Company's  currently
contemplated  operations, the Company's  business plan and  current economic and
industry conditions  and  is subject  to  reapportionment among  the  categories
listed above or to new categories in response to, among other things, changes in
its   plans,  economic   and  industry   conditions  and   future  revenues  and
expenditures. The amount  and timing of  expenditures will vary  depending on  a
number of factors, including changes in the Company's contemplated operations or
business plan and changes in economic and industry conditions.
 
   
    Based  on the  Company's business  plan, the  Company believes  that the net
proceeds  of  this  offering,  together  with  funds  generated  by   continuing
operations,  will be sufficient to permit  the Company to conduct its operations
as currently contemplated for at least the next 18 months. Such belief is  based
on,  among  other  things, budgeted  revenues  from product  sales  and budgeted
expenses, and there can be no  assurance that such resources will be  sufficient
for  such purpose. The  Company may be required  to raise substantial additional
capital in the future in order to expand operations. In addition,  contingencies
may  arise which may require the Company to obtain additional capital. There can
be no assurance that the  Company will be able to  obtain such capital from  any
other   sources  on  favorable  terms  or  at  all.  See  "Capitalization,"  and
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations."
    
 
    Pending  the use  of the  net proceeds for  the above  purposes, the Company
intends  to  invest  such  funds  in  short-term,  investment-grade  securities,
including government obligations and money market instruments.

    The following table sets forth the short term debt and capitalization of the
Company at June 30, 1996 (i)  on an actual basis, (ii)  on a pro forma basis  to
reflect  the mandatory conversion  of the 83,332 shares  of outstanding Series A
Preferred Stock into  304,290 shares of  Common Stock upon  the closing of  this
offering  and (iii) on a pro forma, as adjusted basis to reflect such conversion
and to  give effect  to the  application by  the Company  of the  estimated  net
proceeds  from the sale of the Shares, assuming an initial public offering price
of $5.00  per  Share. See  "Use  of Proceeds."  This  table should  be  read  in

                                    DILUTION
 
   
    The  pro forma net tangible book value  (deficit) of the Company at June 30,
1996, was  $(140,338), or  $(0.08) per  share  of Common  Stock. Pro  forma  net
tangible  book value  per share of  Common Stock represents  the tangible assets
(total assets less  intangible assets)  less total liabilities,  divided by  the
number  of  shares  of  Common  Stock  outstanding  assuming  conversion  of all
outstanding shares  of the  Company's  Series A  Preferred Stock.  After  giving
effect  to the sale  of the Shares  offered hereby at  an assumed initial public
offering price  of $5.00  per Share  and  the application  of the  net  proceeds
therefrom,  the net  tangible book value  of the  Common Stock at  June 30, 1996
would have been approximately $4,659,662 or $1.62 per share. This represents  an
immediate  increase in net  tangible book value  of $1.70 per  share to existing
shareholders and an immediate dilution to new investors of $3.38 per share.

GENERAL
 
   
    The  Company  designs,  develops,  manufactures  and  markets  products  for
real-time, precise, free-hand, localization of points in 3D space. The Company's
optical localizers typically  consist of  a number  of custom-manufactured  LEDs
mounted  to  the device  or instrument  to be  tracked in  3D space,  a relative
position  dynamic  reference  device  connected   to  the  measured  object,   a
multi-camera   array   for   detecting   the   LED   emissions,   a  proprietary
microprocessor-based  control  system  and  proprietary  software.  The  Company
shipped  its  first product  in 1992.  It introduced  its current  products, the
FlashPoint 5000 and the Pixsys 5000, in the spring of 1995.

RESULTS OF OPERATIONS
 
    SIX MONTHS ENDED JUNE 30, 1996 AND 1995
 
   
    Revenue increased by  $1,249,800, or approximately  252%, to $1,746,700  for
the  six months ended June 30, 1996, as  compared to $496,900 for the six months
ended June 30, 1995. Such increase was attributable to the introduction and sale
of the FlashPoint 5000 and Pixsys 5000 Products.
    
 
    Cost of goods sold increased by $474,900, or approximately 183%, to $733,800
for the six months ended June 30, 1996, compared to $258,900 for the six  months
ended  June 30, 1995. Cost of goods sold as a percentage of revenue decreased to
42% for the  six months  ended June 30,  1996, as  compared to 52%  for the  six
months  ended June 30, 1995. The increase in cost of goods sold was attributable
to increased sales volume and the decrease in cost of goods sold as a percentage
of revenue was primarily attributable to  the resulting economies of scale  from
higher production volume.
 
    Gross profit increased by $774,900, or approximately 326%, to $1,012,900 for
the  six months ended June 30, 1996, as  compared to $238,000 for the six months
ended June 30, 1995. Such increase was primarily attributable to the increase in
sales volume.
 
    Research and  development expenses  decreased by  $56,400, or  approximately
15%, to $328,400 for the six months ended June 30, 1996, as compared to $384,800
for the six months ended June 30, 1995. This decrease was principally due to the
reduction  of costs  associated with the  completion of the  FlashPoint 5000 and
Pixsys 5000, which products were released during the second quarter of 1995.
 
   
    Selling and marketing expenses decreased by $128,700, or approximately  36%,
to  $224,500 for the six months ended June 30, 1996, as compared to $353,200 for
the six months ended June 30, 1995. Such decrease was primarily attributable  to
the  Company's decision to focus its sales  and marketing efforts on selling its
FlashPoint product to medical  device companies rather  than also attempting  to
sell  SNT's  ear, nose  and throat  ("ENT")  system directly  to end  users. The
Company decided to
    
 
                                       17
<PAGE>
   
terminate its efforts to sell SNT's  ENT system because the Company believed  it
could  better utilize its resources by  concentrating on sales of its FlashPoint
product  to  its  medical  device  customers.  See  "Business  --   Intellectual
Property."
    
 
   
    General  and administrative expenses increased  by $59,500, or approximately
25%, to $296,400 for the  six months ended June  30, 1996, compared to  $236,900
for the six months ended June 30, 1995. Such increase was primarily attributable
to additional personnel and associated costs.
    
 
   
    Operating  income increased by $900,500 to $163,500 for the six months ended
June 30, 1996,  compared to an  operating loss  of $737,000 for  the six  months
ended  June  30, 1995.  This increase  was  primarily attributable  to increased
revenue, improved gross margin and decreased total operating expenses.
    
 
    Net other income  (expense) decreased by  $48,800 to ($37,700)  for the  six
months  ended June 30, 1996 from $11,100 for the six months ended June 30, 1995.
This change  was  primarily due  to  interest  expense of  $44,100  incurred  in
connection  with the  funds borrowed  by the  Company during  1995. See "Certain
Transactions."
 
   
    As a result of the foregoing, net  income increased to $125,800 for the  six
months  ended June  30, 1996,  compared to a  net loss  of $725,900  for the six
months ended June 30, 1995.
    
 
    Income taxes are  accounted for  in accordance with  Statement of  Financial
Accounting Standards No. 109. Due to the Company's history of pre-tax losses and
uncertainty  surrounding the timing  of realizing the  benefits of net operating
loss carryforwards, the Company has  recorded a valuation allowance against  all
of  its net deferred tax  assets as of June 30,  1996. In reaching the Company's
determination of the  need to provide  a deferred tax  valuation allowance,  the
Company  considered all available evidence, both  positive and negative, as well
as the weight and importance given to such evidence. Management concluded that a
valuation allowance against deferred tax  assets was appropriate at the  current
time,  in accordance with  Statement of Financial  Accounting Standards No. 109.
Specifically, the Company has had annual losses  in each of the two years  ended
December 31, 1994 and 1995, and has only had net income for the six months ended
June 30, 1996.
 
    YEARS ENDED DECEMBER 31, 1995 AND 1994
 
   
    Revenue  increased by $975,700, or approximately 107%, to $1,883,800 for the
year ended  December  31, 1995,  as  compared to  $908,100  for the  year  ended
December  31, 1994. Such  increase was primarily  attributable to the commercial
introduction and sale of the FlashPoint 5000 and Pixsys 5000 products.
    
 
    Cost of goods sold increased by $291,000, or approximately 58%, to  $793,600
for  the year ended December  31, 1995, compared to  $502,600 for the year ended
December 31, 1994. Cost of  goods sold as a  percentage of revenue decreased  to
42%  for the year ended December 31, 1995, as compared to 55% for the year ended
December 31, 1994. The increase in cost of goods sold was primarily attributable
to the  increased  revenue during  the  year ended  December  31, 1995  and  the
decrease  in  cost  of goods  sold  as  a percentage  of  revenue  was primarily
attributable to the resulting economies of scale from higher production volume.
 
   
    Gross profit increased by $684,700, or approximately 169%, to $1,090,200 for
the year  ended December  31, 1995,  compared  to $405,500  for the  year  ended
December  31, 1994. Such  increase was principally  a result of  the increase in
revenue.
    
 
   
    Research and development  expenses increased by  $335,800, or  approximately
115%, to $627,300 for the year ended December 31, 1995, compared to $291,500 for
the  year ended  December 31,  1994. This  increase was  principally due  to the
development of  the  FlashPoint  5000  and  Pixsys  5000  products,  which  were
commercially introduced during the second quarter of 1995.
    
 
   
    Selling  and marketing expenses increased by $162,000, or approximately 27%,
to $767,700 for the year ended December  31, 1995, compared to $605,700 for  the
year  ended  December 31,  1994. Such  increase  was primarily  a result  of the
Company's plan  to sell  SNT's ENT  system,  which effort  ended in  the  fourth
quarter of 1995. See "Business--Intellectual Property."
    
 
                                       18
<PAGE>
   
    General  and administrative expenses increased  by $44,200, or approximately
8%, to $595,600 for the year ended  December 31, 1995, compared to $551,400  for
the year ended December 31, 1994. Such increase was attributable to the addition
of personnel and related expenses.
    
 
   
    Operating  loss decreased by $142,700, or approximately 14%, to $900,400 for
the year ended December  31, 1995, compared to  an operating loss of  $1,043,100
for  the year ended December 31,  1994. This decrease was primarily attributable
to increased revenue.
    
 
    Net other expenses, comprised principally of interest expense, increased  by
$134,400  (781%) to $151,600 for  the year ended December  31, 1995 from $17,200
for the year ended December 31, 1994 due to additional borrowings in 1995.
 
   
    As a result of the foregoing, net loss decreased by $8,400, or approximately
1%, to $1,051,900 for the year  ended December 31, 1995, compared to  $1,060,300
for the year ended December 31, 1994.
    
 
    Income  tax benefits were not recognized on  the Company's 1994 and 1995 net
operating losses due to  the uncertainty surrounding  the future utilization  of
such  net operating losses. As of December 31, 1995, the Company's net operating
loss carryforwards were  approximately $2,788,000  which expire  from the  years
2006  to 2010. The Company's ability to use the net operating loss carryforwards
are limited  due to  certain changes  in ownership  as defined  by the  Internal
Revenue Code. Due to the Company's history of pre-tax losses and the uncertainty
surrounding  the  timing  of  realizing  the  benefits  of  net  operating  loss
carryforwards, the Company has placed a valuation allowance against its deferred
tax assets. See Note 6 of Notes to Financial Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    During the six months ended June 30, 1996, the Company used $154,400 in cash
for operating  activities, principally  to fund  increased accounts  receivable,
inventories  and  other  assets.  The  Company also  used  $77,100  in  cash for
investing activities during the six month period ended June 30, 1996 to purchase
property and equipment. Also  during the six month  period ended June 30,  1996,
$337,500 in cash was provided by the exercise by certain warrantholders of their
warrants to purchase 270,000 shares of Common Stock. See "Certain Transactions."
    
 
   
    During  1995, the Company issued $775,000  in promissory notes, all of which
are scheduled to mature on the earlier of the closing of a public offering  with
gross  proceeds of at least $5,000,000 or  June 30, 1997. In connection with the
issuance of  such  notes  (and  the warrants  coupled  therewith),  the  Company
recorded  a debt discount of  $131,700 in 1995. As of  June 30, 1996, $86,300 in
interest had accrued on  these notes. The Company  intends to pay the  principal
amount  of,  and accrued  and unpaid  interest on,  these notes  in full  with a
portion of the proceeds of this offering. See "Certain Transactions" and "Use of
Proceeds."
    
 
   
    As of June 30, 1996, the Company  had a working capital deficit of  $296,800
compared  to a working capital  deficit of $695,100 at  December 31, 1995 (which
included $861,300 and $818,200, respectively, of principal and interest owed  on
the  loans which are to be repaid in connection with this offering). See "Use of
Proceeds". The  improvement  in working  capital  was primarily  the  result  of
increases  in  accounts  receivable,  inventories and  cash  resulting  from the
Company's 1996  net  income and  the  exercise of  the  warrants.  Historically,
working  capital required to  finance the Company's growth  has been provided by
short-term borrowings and private placement offerings of securities. As of  June
30, 1996, the Company did not have a line of credit.
    
 
   
    Based  on the  Company's business  plan, the  Company believes  that the net
proceeds  of  this  offering,  together  with  funds  generated  by   continuing
operations,  will be sufficient to permit  the Company to conduct its operations
as currently contemplated for at least the next 18 months. Such belief is  based
on  certain assumptions, and there can be  no assurance that such resources will
be sufficient for such purpose. The Company may be required to raise substantial
additional capital in  the future in  order to expand  operations. In  addition,
contingencies  may  arise which  may require  the  Company to  obtain additional
capital. There can be no assurance that the Company will be able to obtain  such
capital on favorable terms or at all. See "Use of Proceeds."

                                    BUSINESS
 
GENERAL
 
   
    The  Company  designs,  develops,  manufactures  and  markets  products  for
real-time, precise, free-hand, localization of points in 3D space. The Company's
optical localizers, typically consisting of a number of custom-manufactured LEDs
mounted on a device or instrument to be tracked in 3D space, a relative position
dynamic reference device connected to the measured object, a multi-camera  array
for  detecting  the LED  emissions,  a proprietary  microprocessor-based control
system and proprietary software to calculate the digital coordinate location  of
the LEDs, have both medical and industrial applications.
    
 
   
        MEDICAL  APPLICATIONS.   The  Company's  FlashPoint localizer  is  a key
    component of the anatomical image display workstation used by physicians  to
    perform  image  guided  surgery,  a  specialty  procedure  in  the  field of
    minimally invasive surgery. When the  FlashPoint localizer is combined  with
    the  imaging software  provided by the  Company's customers  (such as Zeiss,
    GEMS, SNT/ Sofamor Danek, DeeMed  and Radionics), the location of  specially
    designed  surgical instruments can  be tracked in  relation to the patient's
    anatomy during surgical procedures by display as an overlay on the MRI or CT
    image. The Company  believes that the  ability of the  surgeon to track  the
    location  of specially  designed surgical  instruments on  the image display
    workstation can  result in  less invasive  procedures that  lead to  shorter
    hospital stays and improved patient outcomes.
    
 
   
        INDUSTRIAL  APPLICATIONS.   The  Company's Pixsys  localizer is  used in
    various industrial applications to measure the position or shape of  objects
    in   3D   space.  Illustrative   uses   include  inspection   of   parts  by
    Harley-Davidson, Inc., detection of surface deformities in car bodies during
    manufacture by Daimler Benz and as a  3D navigation aid in its zero  gravity
    chamber by NASA.
    
 
    The Company's business strategy is to systematically enhance the performance
of  its optical  localizers while expanding  the market for  such products. With
respect to  enhancing its  products,  the Company  is  seeking to  increase  the
products'  accuracy, enlarge the field-of-view,  increase the sample/ frame rate
(throughput) and improve the customer computer interface. With regard to  market
expansion,   the  Company   is  seeking   to  identify   additional  measurement
applications for its products.
 
IMAGE GUIDED SURGERY
 
   
    In image guided surgery, a surgeon tracks the location of specially designed
surgical instruments on  the medical  image (such as  CT or  MRI). Image  guided
surgery  requires a  method for  registering (i.e.,  mapping) the  points in the
medical image onto  the patient's  anatomical physical  space and  a method  for
localizing  (i.e., determining the  position in 3D space)  the surgical probe or
pointer. Surgical position  of the  probe or pointer  is key  to the  successful
completion of a surgical procedure.
    
 
   
    Localization  determines the position in 3D space of the registration points
and the surgical probe or pointer. The Company's FlashPoint product is used as a
localizer for medical applications.
    
 
   
    Until registered,  the medical  image  is only  a  picture of  the  relevant
anatomy  and not a map.  By registering the image  space with the physical space
itself, the image  is said  to have been  registered. By  registering the  image
space  with the physical space, medical  images become true, point-to-point maps
available for precise surgical  guidance. The imaging  software provided by  the
Company's medical customers registers the medical image with the physical space.
    
 
    Traditionally,  pre-operative  medical  images  (such  as  CT  or  MRI) were
available as pictures that were used  for surgical guidance only insofar as  the
judgment,  skill and experience of the  surgeon permitted. Prior to surgery, the
surgeon arranged the patient's  CT or MRI  scans (images) upon  a light box  and
carefully  reviewed  them.  Upon  commencement of  the  surgical  procedure, the
surgeon, based  upon his  or her  memory of  the information  displayed on  such
images, performed the surgical procedure.
 
                                       20
<PAGE>
   
    Image  guided surgery,  by allowing the  patient's CT, MRI  or other medical
image to  be  used as  a  map, provides  the  surgeon with  a  real-time  visual
representation  of  the surgical  probe or  pointing  device on  the interactive
medical image. It  allows the spatial  position of  the probe or  pointer to  be
tracked  during the surgical procedure and to  be displayed as an overlay on the
medical image  shown  on  the  workstation. The  medical  image  may  either  be
historical  (i.e., pre-operative)  as in  the products  currently being  sold by
Zeiss,  SNT/Sofamor   Danek,  DeeMed   and   Radionics,  or   real-time   (i.e.,
intraoperative)   as   in   the   product   being   developed   by   GEMS.   See
"Business--Customers and Use."
    
 
    Image guided surgery couples recent advances in imaging with the instruments
used in the course of surgery. The result, the Company believes, can be smaller,
less invasive  procedures  that lead  to  shorter hospital  stays  and  improved
patient  outcomes. While image guided surgery  has been most extensively used in
neurosurgery, the Company  anticipates that  image guided  surgery will  provide
benefits  for ear, nose and throat  surgery, needle biopsies, orthopedics (e.g.,
hip replacement surgery), maxillofacial surgery and radiosurgery.
 
PRODUCTS
 
    The FlashPoint and Pixsys localizers consist  of a number of markers  (LEDs)
mounted  on a pointer device or surgical instrument, a relative position dynamic
reference device ("Dynamic Reference Frame") connected to the measured object (a
patient in a  medical application  or a part  in an  industrial application),  a
multi-camera  array  for detecting  the  X, Y  and Z  positions  of the  LEDs, a
proprietary microprocessor based control  system, and a proprietary,  internally
developed,  software  package.  The  Company's  optical  localizer  is  an input
subsystem providing real-time mathematical coordinates  to a host computer.  The
Company's  optical localizer determines  the position of  the hand-held probe or
surgical instrument and the patient reference device by tracking the X, Y and  Z
coordinates  of  each infrared  light  emitting diode  mounted  on the  probe or
surgical instrument and reference device. It then communicates this position  in
the form of X, Y and Z coordinates to the host computer.
 
    DYNAMIC  REFERENCE FRAME.  The Dynamic Reference Frame, typically three LEDs
mounted on a fixed frame, allows the patient to be moved during an image  guided
surgical procedure while maintaining registration between the scanned image, the
surgical instrument and the patient. Without this type of feature, the physician
would  be  unable  to  move the  patient,  or,  if the  patient  was  moved, the
registration process would have to be  repeated, adding significant time to  the
surgical procedure.
 
   
    INSTRUMENTS.    The  Company,  in conjunction  with  custom  fabricators and
surgical instrument manufacturers, provides various instruments, such as  probes
and  pointers, containing LEDs as component parts to its optical localizers. For
medical applications, the  LED is  placed on  the instrument,  and the  distance
between  the LED and  the tip of  the instrument is  precisely calibrated. These
instruments are designed to be reused on  a limited basis. The Company plans  to
design  and market other instruments,  some of which may  be disposable, for use
with its localizer.
    
 
   
    MARKERS.  The Company's present line of optical localizers utilize  infrared
LED  markers, the positions  of which are  tracked by the  FlashPoint and Pixsys
systems. Because the emission characteristics of each LED affects overall system
performance, the Company  provides a  custom-manufactured line of  LEDs for  its
products.  The  LEDs are  consumable items  and,  depending upon  the customer's
application, the life expectancy varies.
    
 
   
    Most localizers  sold by  the  Company are  customized to  satisfy  customer
requirements.  Not all customers purchase  Dynamic Reference Frames, instruments
or markers from the Company.

    The FlashPoint and Pixsys localizers have a mean accuracy of better than 0.4
mm with a maximum error within a 1 meter sphere of less than 1 mm. This accuracy
is achieved both  through the design  of the product  and through the  use of  a
highly accurate calibration process. The device used to calibrate the FlashPoint
and  Pixsys products is a Zeiss DB 900 4860-36 bridge type, dual beam Coordinate
Measuring Machine ("CMM"). The  CMM is a measurement  device which has a  linear
displacement  accuracy of:  X axis =  0.0076 mm,  Y axis =  0.0102 mm,  Z axis =
0.0064 mm,  and a  volumetric performance  of 0.0165  mm. The  CMM is  routinely
calibrated  to, and the  results are traceable to  the appropriate standards of,
the   National   Institute   of    Science   and   Technology   ("NIST").    See
"Business--Manufacturing Operations."
    
 
CUSTOMERS AND USE
 
   
    MEDICAL APPLICATIONS
    
 
   
    The  Company's FlashPoint  product is used  to determine the  position in 3D
space of the surgical probe or  instrument. The FlashPoint 5000 medical  optical
localizer  is  a  component  currently  being  integrated  into  medical devices
manufactured by GEMs, Zeiss, SNT\Sofamor Danek, DeeMed and Radionics.
    
 
    GE MEDICAL  SYSTEMS, MILWAUKEE,  WISCONSIN.   In 1993,  GEMS introduced  its
magnetic resonance guided therapy ("MRT") system which provides direct physician
access  to  the patient  during imaging,  giving a  real-time, internal  view of
patients for procedures such as needle biopsies. MRT is currently used to  plan,
guide and monitor surgical procedures in a minimally invasive manner. FlashPoint
is  being used by  GEMS for the guidance  system in its  MRT device. The initial
GEMS MRT system is at Harvard University's Brigham and Women's Hospital. GEMS is
currently shipping this system to clinical sites worldwide and is preparing  its
submission to the FDA.
 
   
    CARL  ZEISS,  INC.,  THORNWOOD,  NEW  YORK,  A  SUBSIDIARY  OF  CARL  ZEISS,
OBERKOCHEN, GERMANY.  The  Company's FlashPoint product is  an integral and  key
component  of the Zeiss SMN Stereotactic System. By combining imaging diagnostic
data with  powerful computers,  precision optics  and finely  crafted  hand-held
instrumentation,  Zeiss  has  created  a product  enhancement  to  its operating
microscope line. In November 1995, Zeiss entered into an OEM agreement with  the
Company  under which the Company provides Zeiss with its optical localizers. The
SMN product is targeted as an enhancement to Zeiss' worldwide installed base  of
surgical microscope systems.
    
 
    SURGICAL   NAVIGATION  TECHNOLOGIES,   INC.,  BROOMFIELD,   COLORADO.    SNT
integrates  FlashPoint  into  its   StealthStation-TM-,  which  offers   precise
real-time  positional information for free-hand  stereotaxy in neurosurgical and
spinal applications.  SNT is  the system  integrator for  Sofamor Danek  Group's
neuro-navigation  system. Sofamor Danek is SNT's exclusive distributor for SNT's
StealthStation and acquired SNT in May 1996.
 
   
    DEEMED INTERNATIONAL, GRENOBLE, FRANCE.  DeeMed incorporates the  FlashPoint
product   into  the  Surgiscope,  its   surgical  robot  utilized  for  accurate
positioning of surgical microscopes. DeeMed first used the FlashPoint system  in
its  initial prototype in early 1993. The original system continues in operation
at Necker Hospital, Paris, France. DeeMed  was acquired by Electa Instrument  AB
in July 1996.
    
 
   
    RADIONICS  SOFTWARE  APPLICATIONS, INC.,  A  SUBSIDIARY OF  RADIONICS, INC.,
BURLINGTON, MASSACHUSETTS.  Radionics employs  the FlashPoint  in the  Radionics
Optical  Tracking  System for  Frameless  Stereotaxy. This  real-time, free-hand
stereotaxy system  is primarily  used in  neurosurgical applications.  Radionics
began  using  an  earlier model  of  the  FlashPoint in  1994  and  has recently
incorporated the latest generation FlashPoint product into its system.
    
 
   
    INDUSTRIAL APPLICATIONS
    
 
    The Company's Pixsys product is used  to determine the position or shape  of
an  object  by rapidly  collecting  a large  number  of points  on  the object's
surface. To date, each  of the Company's industrial  customers has purchased  no
more  than several Pixsys products. The  following sets forth several indicative
ways  in  which  the  Pixsys   product  is  used  in  industrial   applications:
Harley-Davidson uses
 
                                       22

such  product to inspect parts; Daimler Benz uses such product in its system for
detecting surface deformities in  car bodies during  manufacture; and NASA  uses
such  product  as a  3D navigation  aid in  its zero  gravity chamber.  Sales to
industrial customers  constituted approximately  24% of  sales in  1994, 11%  of
sales in 1995 and 11% of sales during the first six months of 1996.
    
 
   
    The  Company is seeking additional applications  for its Pixsys product. For
example, Brewco, Inc.,  Central City, Kentucky  ("Brewco"), has contracted  with
the  Company for the Company  to develop a proof of  concept model of its Pixsys
product for  use  with  Brewco's frame  straightening  machines  for  automobile
collision repair. If the concept proves viable, the parties contemplate entering
into  an OEM  agreement pursuant  to which  the Company  will supply  its Pixsys
product to Brewco  and Brewco  will incorporate the  Pixsys into  its system  to
measure  the  distortion  caused  by  the  collision  and  the  results  of  the
straightening operation.  There can  be  no assurance,  however, that  any  such
product  will be developed, or if developed,  be economical or accurate, or that
the parties will enter into an OEM agreement.
    
 
MARKETING AND SALES
 
   
    The Company employs a  marketing strategy focused  on selling its  localizer
under  OEM  agreements  to  a  number of  medical  device  companies.  Since the
localizer is  a key  component  in the  medical  device company's  image  guided
surgery  system and since  the medical device  company has to  design its system
specifically to incorporate the  localizer, the OEM  agreements are intended  to
assure  the medical device company that the Company will be a reliable supplier.
The Company anticipates that it may make available source code escrow agreements
to the medical device company which, in appropriate circumstances, may grant the
medical device  company  the license  to  manufacture the  localizer  using  the
Company's technology for the purpose of incorporating it into the medical device
company's  product if  the Company  is unwilling  or unable  to comply  with its
obligations under the OEM agreement.
    
 
   
    The Company currently has OEM  agreements with Zeiss, DeeMed and  Radionics;
GEMS  and SNT/Sofamor Danek  do not have supply  agreements and instead purchase
product by  purchase order.  Zeiss' agreement  with the  Company is  a  one-year
agreement  for a fixed number of units at  a fixed price that expires at the end
of October 1996.  DeeMed's agreement is  a five-year agreement  with no  minimum
purchase  requirements, though  the agreement can  be terminated  by the Company
after three years if a  minimum number of units  has not been purchased.  Prices
are  subject  to  annual  renegotiation. Radionics'  agreement  is  a three-year
agreement with no minimum  purchase requirements. Prices  are subject to  change
upon  90 days prior written notice by  the Company. Since there are no long-term
purchase requirements  with  any  of  the Company's  customers,  past  sales  to
customers may not be indicative of orders or purchases in any future period. See
"Business--Backlog."
    
 
   
    The Company's industrial marketing strategy includes selling pursuant to OEM
and  value added reseller ("VAR") agreements to companies which will include the
Company's Pixsys  product  in their  systems  for industrial  applications.  The
Pixsys  product used  by Harley-Davidson was  sold to Computer  Design, Inc. and
integrated into its  proprietary CAD (computer  aided design) software  package.
The Company also has a domestic sales representation agreement with SANDAB, Inc.
("SANDAB")  under  which  SANDAB  has  been  appointed  the  Company's exclusive
representative  to  sell  the  Company's  products  to  non-medical  users,  but
including  dental  and  orthodontic  users, in  the  States  of  Michigan, Ohio,
Pennsylvania and West Virginia and the Province of Ontario and as the  Company's
non-exclusive  representative in  the State  of Indiana.  This agreement  can be
terminated on 90 days  advance written notice by  either party, but  commissions
will continue to be due on orders received prior to termination.
    
 
BACKLOG
 
   
    At  December 31, 1995, the Company's backlog  was $1,832,700 and at June 30,
1996 it was $870,600. Since backlog fluctuates depending on how customers  order
their  products and  over what  period of time,  the Company  currently does not
consider backlog to be a meaningful indicator of future sales.

COMPETITION
 
   
    Although 3D localization can be  performed in a number  of ways, the use  of
LEDs  as  markers  and  optical  sensor arrays  as  receivers  is  currently the
technology  of  choice  for  manufacturers  of  image  guided  surgery  systems.
Currently,  two  designs  of  optical localizers  are  available.  The Company's
FlashPoint product, as  well as  the NDI OPTOTRAK-Registered  Trademark-, use  a
technical  approach that  employs three  linear photo  detectors, also  known as
linear charge coupled devices  ("CCDs"), in the camera  assembly. Each of  these
linear  arrays has  between 2000 and  5000 discrete CCD  elements called pixels,
arrayed in a single line which can be quickly scanned to determine the  location
of   the  light  energy   being  detected.  The   second  approach  employs  two
two-dimensional arrays having between 250 to 1000 elements (pixels) in each  row
of  a CCD that is arrayed in a matrix  of equal length rows and columns. In this
configuration, the CCD array must be scanned sequentially through each row  from
top to bottom, the same as a standard television camera, to measure the location
of  the light  energy being emitted.  Since the  linear array CCD  has a greater
number of pixels than any row of  the two-dimensional (matrix) CCD, there is  an
increased  resolution  in  the  linear  array  which  contributes  to  increased
accuracy. Additionally, since the linear array only needs to be scanned from end
to end to measure the light being detected and the 2D array must be scanned from
the beginning of the  top row to the  end of the bottom  row in the matrix,  the
linear array systems can provide faster throughput of measurements.
    
 
   
    The  Company  believes it  is  currently a  leader  in the  sale  of optical
localizers to  the  medical market.  The  Company's primary  competitor  in  the
medical  OEM market is NDI. NDI markets both the OPTOTRAK and the Polaris to the
medical OEM marketplace. The OPTOTRAK is  a high performance 3D, infrared  based
optical  localizer having a selling price of approximately $60,000. Although the
OPTOTRAK has been found  useful in motion tracking,  its physical size and  cost
have generally limited its medical applications to proof-of-concept and research
applications.  In  April 1996,  NDI introduced  the  Polaris, an  infrared based
optical localizer using  two two-dimensional CCD  cameras. Preliminary  feedback
from  the marketplace indicates the Polaris  has reduced performance compared to
the OPTOTRAK  and  has  an  approximate  selling  price  of  $25,000,  which  is
comparable  to  the  Company's  list price  for  its  FlashPoint  product. Other
companies, such as Phillips Medical Systems and BrainLab GmbH have developed two
camera optical localization  devices for  their prototype  image guided  surgery
systems.  The  Company believes  competition with  respect  to sales  of optical
localizers is based primarily on price, ease of use, ability to satisfy customer
requirements and accuracy.
    
 
   
    Companies have also attempted to  use other mediums as localization  devices
for medical applications. For example, much of the early technical work relative
to  medical applications  involved the tracking  of sound  markers. The inherent
characteristics of the sound markers used in medical applications, coupled  with
the  technical  limitations of  the  use of  sound based  systems  in an  MRI or
operating room environment, hampered the medical application of this technology.
Only one major medical company used the sonic technology. That company no longer
uses such technology. Sonic technology is still used in industrial  applications
because of its ability to make measurements in large fields-of-view.
    
 
    Mechanical  arm localizers  are used extensively  in industrial application,
but are used as the basis of only two medical devices. In medical  applications,
the  "feel" and range of motion of the arm impose significant constraints on the
surgeon, thus  limiting  the  use  of  the  device.  Similarly,  magnetic  field
digitizers  have also been used in,  or evaluated for, such applications. Errors
caused by the movement of metal components in and around the surgical field have
made these  magnetic  field  localizers impractical  for  most  general  surgery
applications.
 
    Companies  other than NDI may also  become competitors. Competitors may have
substantially greater financial, technical,  marketing, manufacturing and  human
resources,  as well  as name recognition,  than the Company.  Competitors may be
able to respond  more quickly  to new or  emerging technologies  and changes  in
customer  requirements  and to  devote  substantially greater  resources  to the
research and development, marketing and sale of their products than the Company.
Also, the Company's customers may determine  to develop their own localizers  to
insure control over their
 
                                       24
<PAGE>
localizer  technology or  for other  reasons. Furthermore,  such competitors may
develop technology  other  than that  based  on  infrared optics  that  is  more
effective or economical than the technology of the Company in localizing a point
in 3D space. See "Risk Factors--Competition."
 
MANUFACTURING OPERATIONS
 
    The  Company's manufacturing activities primarily  consist of assembling and
testing components and subassemblies acquired from qualified vendors, as well as
final assembly and testing of the Company's fully-configured systems. Components
are generally available from  several sources although  the order lead-time  for
the  semi-custom isolated power  supply used in the  FlashPoint 5000 varies from
four to six  months. The  Company's recent relocation  to its  new facility  has
allowed  it to  expand its  manufacturing space.  The new  facility has adequate
expansion room to nearly double the manufacturing space presently being used. An
integrated manufacturing planning and control computer system is in place  which
provides for material requirements planning and inventory control, manufacturing
planning  and  scheduling and  production work  order tracking.  See "Business--
Facilities."
 
    The  Company  recently  made  a   significant  investment  to  improve   the
calibration  process  for the  products being  shipped to  its customers.  A CMM
measurement device was leased and installed in the new facility. This new system
provides  a  higher  degree  of  accuracy  and  consistency  in  the   Company's
calibration  process and  gives the  Company a  final calibration  tool which is
traceable to  NIST standards.  The CMM  system  is also  used by  the  Company's
research  and  development  staff  for research  and  development  projects. See
"Business--Products."
 
INTELLECTUAL PROPERTY
 
   
    The Company  has  been  issued  U.S.  Patent  5,198,877  on  its  SprayLight
technology  which is  a non-contact,  laser based,  hand-held 3D  localizer that
allows the  user to  acquire simply  and easily  a multitude  of points  on  the
surface of an object or anatomy by sweeping a hand-held scanner over the desired
target.  This patent  expires in 2010  and its  claims do not  cover any product
currently being  sold  by  the  Company.  The  Company  has  filed  four  patent
applications  with  the U.S.  Patent and  Trademark Office  (three of  which, if
granted, relate to current uses of the Company's product and the other of which,
if granted, may cover  future products) and  has submitted several  applications
for  patents  to various  international  patent agencies.  However,  the Company
primarily relies on a combination of  trade secret and copyright laws,  together
with  non-disclosure agreements, to establish  and protect proprietary rights in
its products. The  non-disclosure agreements generally  prohibit disclosure  and
use  of the Company's confidential information by the parties to the agreements.
Since trade  secret,  copyright and  non-disclosure  agreements do  not  protect
against  reverse engineering or independent invention, there can be no assurance
that the steps taken by  the Company to protect  its proprietary rights will  be
adequate to prevent misappropriation of its technology.
    
 
    The  Company's  optical localizer  is  a complicated  measuring  device. Its
software contains elaborate mathematical  modeling and its manufacture  requires
precise  production and careful calibration. The  Company believes that it would
be impractical and not cost-effective for third parties to attempt to  duplicate
the   Company's   software   and  production   process.   Unauthorized  parties,
nevertheless, may attempt to copy aspects of the Company's products or to obtain
and use  information  that the  Company  regards  as proprietary.  The  cost  of
enforcement  by  the Company  of its  proprietary  rights could  be significant,
regardless of  the  outcome  of  such  enforcement  proceedings.  Moreover,  the
Company's  proprietary rights will  not prevent competitors  of the Company from
developing  their  own  localizers  using   their  own  technology.  See   "Risk
Factors--Absence of Patent Protection" and "Risk Factors-- Competition."
 
   
    On  January 24, 1995, St.  Louis University was granted  a patent covering a
particular technique for determining the position  of a surgical probe within  a
patient's  body on  an historical  image of  that body.  Shortly thereafter, the
Company entered into an agreement with SNT, under which, among other things, (i)
the Company agreed to supply, and SNT agreed to purchase, the Company's  optical
localizer,  (ii) the  Company agreed  not to sell  its optical  localizer to any
customer whose use would knowingly infringe the SLU Patent and (iii) the Company
was granted the exclusive right, subject to
    
 
                                       25
<PAGE>
   
certain minimums, to sell SNT's image display workstations to ENT (ear, nose and
throat) customers  worldwide.  The agreement  with  SNT was  terminated  at  the
Company's  request in the fall of 1995 due to the Company's decision to focus on
the  sale  of  its   FlashPoint  product  to   medical  device  customers.   See
"Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations-- Results of Operations." SNT/Sofamor Danek remains a key customer of
the Company.  The  Company  believes  that  the  manufacture  and  sale  of  its
FlashPoint localizer does not infringe the SLU Patent, since a localizer is only
a  component  part  in  the  system patented  by  SLU  and  since  the Company's
FlashPoint localizer has substantial non-infringing uses. Under one part of  the
agreement  with SNT which was not terminated,  the Company assigned to St. Louis
University all right, title  and interest it  had in the  SLU Patent. See  "Risk
Factors--Customer Concentration; Patents on Systems That Utilize Localizers" and
Risk Factors--Absence of Patent Protection."
    
 
   
    The   Company  recently  entered  into   a  license  agreement  with  Vexcel
Corporation pursuant  to  which  Vexcel  granted  the  Company  a  non-exclusive
world-wide license to make, use and sell products covered by Vexcel's mandibular
motion  monitoring  system. This  license  may be  of  value in  connection with
systems utilizing the Company's products in maxillofacial surgery.
    
 
GOVERNMENT REGULATION
 
   
    The Company's FlashPoint localizer is incorporated into medical devices that
are subject  to extensive  regulation by  the  FDA and,  in some  instances,  by
foreign   and  state  governments.  The  FDA  regulates  the  clinical  testing,
manufacture, labeling, distribution and promotion  of medical devices. Before  a
new  device can be  introduced into the market,  the manufacturer must generally
obtain market clearance through either the 510(k) premarket notification process
or the lengthier  and more  costly PMA application  process. Noncompliance  with
applicable  requirements can result in,  among other things, fines, injunctions,
civil penalties, recall or seizure of  products, total or partial suspension  of
production,  failure of the government to grant premarket clearance or premarket
approval  for   devices,  withdrawal   of  marketing   approvals  and   criminal
prosecution.  The FDA also  has the authority to  request repair, replacement or
refund of the cost of any device.
    
 
   
    In the United States, medical devices are classified in one of three classes
(Class I, II or III), on the basis  of the controls deemed necessary by the  FDA
to  reasonably  assure their  safety and  effectiveness. Under  FDA regulations,
Class I  devices  are  subject  to  general  controls  (for  example,  labeling,
premarket  notification and adherence to GMPs)  and Class II devices are subject
to general and special controls (for example, performance standards,  postmarket
surveillance,  patient  registries  and FDA  guidelines).  Generally,  Class III
devices are those  which must receive  premarket approval by  the FDA to  ensure
their  safety and  effectiveness (for  example, life-sustaining, life-supporting
and implantable devices or new devices  which have not been found  substantially
equivalent to legally marketed devices).
    
 
   
    Before a new device can be introduced into the market, the manufacturer must
generally  obtain marketing clearance through either  a 510(k) notification or a
PMA application. A 510(k) clearance will be granted if the submitted information
establishes that the proposed device is "substantially equivalent" to a  legally
marketed Class I or II medical device or to a Class III medical device for which
the  FDA has not called for a PMA. Commercial distribution of a device for which
a 510(k)  notification is  required can  begin only  after FDA  issues an  order
finding  the device to be "substantially  equivalent" to a predicate device. The
FDA has recently  been requiring  a more rigorous  demonstration of  substantial
equivalence than in the past. It generally takes from four to twelve months from
the date of submission to obtain a 510(k) clearance, though it may take longer.
    
 
   
    A  PMA application must be  filed if a proposed  device is not substantially
equivalent to a legally marketed Class I or Class II device or if it is a  Class
III  device  for  which FDA  has  called for  PMAs.  A PMA  application  must be
supported by valid scientific evidence which typically includes extensive  data,
including  human clinical trial data to demonstrate the safety and effectiveness
of the device. The PMA application must also contain the results of all relevant
bench tests, laboratory and animal studies, a complete description of the device
and its components and a detailed description of the
    
 
                                       26
<PAGE>
   
methods, facilities and controls  used to manufacture  the device. In  addition,
the  submission must include  the proposed labeling,  advertising literature and
training methods, if required. The PMA  process can be expensive, uncertain  and
lengthy  and a  number of devices  for which  FDA approval has  been sought have
never been approved for marketing.
    
 
    If human clinical trials of a device are required in connection with  either
a  510(k) notification or a  PMA, and the device  presents a "significant risk,"
the sponsor of  the trial (usually  the manufacturer or  the distributor of  the
device)  is  required  to  file  an  investigational  device  exemption  ("IDE")
application prior to commencing human clinical trials. The IDE application  must
be  supported by data, typically including  the results of animal and laboratory
testing. If the IDE application is reviewed  and approved by the FDA and one  or
more appropriate Institutional Review Boards ("IRBs"), human clinical trials may
begin  at a specific number  of investigational sites with  a specific number of
patients, as approved by the FDA. If the device presents a "nonsignificant risk"
to the patient, a sponsor may begin the clinical trial after obtaining  approval
for the study by one or more appropriate IRBs.
 
   
    The  Company  believes that  the FlashPoint  localizer  is a  medical device
component not subject to the full panoply of the FDA medical device regulations,
including the market clearance requirements. The medical equipment manufacturers
that incorporate  the FlashPoint  localizer into  their products  are,  however,
required   to  obtain  market   clearance  from  the   FDA  for  such  products.
Modifications  to   such  products   manufactured  by   the  medical   equipment
manufacturers   will  require   additional  clearances  or   approvals  if  such
modifications could significantly  effect the  safety and  effectiveness of  the
devices  or  establish a  new  intended use  for the  devices.  There can  be no
assurance that the Company's customers have, with respect to their products that
incorporate FlashPoint localizers, complied or will  be able to comply with  all
applicable  market clearance requirements. Failure on  the part of the Company's
customers to comply with such requirements could have a material adverse  effect
on the Company's business, financial condition and results of operations.
    
 
   
    There can be no assurance that the FDA will not require, or change its rules
or  interpretations so as to require, the Company to obtain 510(k) clearance for
its FlashPoint localizer apart  from, or in addition  to, any market  clearances
obtained  by its medical device customers. Failure of the Company to comply with
such market clearance requirements could have  a material adverse affect on  the
Company's business, financial condition and results of operations.
    
 
   
    Products  manufactured by the Company and  its medical device customers that
incorporate the  Company's  products are  subject  to pervasive  and  continuing
regulation  by the FDA. FDA enforcement  policy strictly prohibits the promotion
of products for any uses  other than those for  which clearance or approval  was
obtained. The Company's manufacturing facilities and those of its medical device
customers  that  incorporate  its  products  may  also  be  subject  to periodic
inspection for compliance with GMP and other regulatory requirements by the  FDA
and comparable state agencies. The Company is currently installing the necessary
systems  and  controls to  become certified  under the  ISO 9001  standards (the
European equivalent to GMPs). This process requires a significant investment  of
time and resources to complete.
    
 
    The  introduction into foreign markets of the Company's FlashPoint localizer
and the products  of the  medical equipment manufacturers  that incorporate  the
FlashPoint  localizer may also subject the Company and such customers to foreign
regulatory clearances and requirements  which may impose additional  substantial
costs  and burdens.  International sales of  medical devices are  subject to the
regulatory requirements  of each  country. The  regulatory process  varies  from
country to country.
 
    Violations  of  regulatory  requirements  of the  FDA  or  foreign  or state
regulatory agencies or changes in such regulations or in interpretations of such
regulations, could have  a material  adverse affect on  the Company's  business,
financial condition and results of operations.

RESEARCH AND DEVELOPMENT
 
    The  Company devotes a significant portion  of its resources to research and
development.  In  1995,  33%  of  revenues  (or  $627,266)  were  spent  on  the
development  and commercial introduction of the FlashPoint 5000 and Pixsys 5000.
The Company has estimated that approximately $1,000,000 (20.8%) of the estimated
net proceeds of  this offering,  assuming an  initial public  offering price  of
$5.00  per Share,  will be  allocated to  fund further  research and development
activities and the Company believes that a substantial amount of capital will be
required to be allocated to such activities in the future.
 
    The  Company  has  developed  core  competencies  in  software  development,
mathematical  modeling of the 3D measurement process, digital signal processing,
circuit design,  computer  system  integration  and  3D  optical  sensor  system
development.  Outside consultants  and contract  engineering are  employed, when
needed, for optical  system design, surgical  instrument development and  safety
engineering.  The Company's  engineers work  closely with  its OEMs  and VARs to
assist in the integration of the Company's products with customer systems and to
identify new applications for the Company's products.
 
   
    The Company  is currently  developing a  family of  infrared optical  camera
systems  to meet a range of  requirements for different sized fields-of-view and
measurement accuracy. Although  optical sensing  systems appear to  be the  best
technology  choice for the present time, the Company's advanced development team
is evaluating a number of methodologies  for detecting and measuring a point  in
space  and/or creating an image of a complex surface. These include a variety of
both passive and active markers, video imaging techniques and advanced  software
and hardware designs.
    
 
   
    The  Company's  product development  engineering staff  is currently  in the
requirements development phase for the FlashPoint 6000, which will have a higher
degree of accuracy,  a larger field-of-view,  a faster sample/frame  rate and  a
more flexible interface to customers' systems. The Company's current target date
for  the release of the  FlashPoint 6000 is in the  first quarter of 1998. There
can be no assurance that this target date  will be met or that the Company  will
successfully develop this product.
    
 
    Additional  projects are in the planning stage to create a series of unique,
proprietary  marker  devices  such  as  high  accuracy  LEDs,  passive  markers,
non-magnetic  markers  for  surgical  instruments  used  in  magnetic  resonance
environments and a  family of probes  and instruments for  both the medical  and
industrial  markets. The Company is currently  considering making some or all of
the probes and  instruments cost effective,  single-use disposable items.  These
are  especially important for  the medical markets served  by the Company. There
can be no assurance, however, that any of these products will be developed.
 
    Although the Company intends to build  on, and expand its current  technical
competencies to introduce new products and product enhancements, it also intends
to  review  compatible,  complimentary technology  for  possible  acquisition or
licensing. See "Use of Proceeds."
 
PRODUCT LIABILITY INSURANCE
 
    The Company faces an inherent business risk of exposure to product liability
claims in the event that the use of its products is alleged to have resulted  in
adverse effects. To date, no product liability claims have been asserted against
the  Company. The Company  maintains a product  liability and commercial general
liability insurance policy  with coverage  of $1,000,000 per  occurrence and  an
annual aggregate maximum coverage of $2,000,000 ($1,000,000 for lawsuits outside
the  United States, Canada and Puerto Rico). The Company's product liability and
general liability policy is  provided on an occurrence  basis and is subject  to
annual  renewal. There can be no assurance that liability claims will not exceed
the coverage limits of such  policy or that such  insurance will continue to  be
available on commercially reasonable terms or at all. If the Company does not or
cannot  maintain  sufficient  liability  insurance, its  ability  to  market its
products could  be materially  adversely affected.  See "Risk  Factors--Risk  of
Product Liability Claims."
 
EMPLOYEES
 
   
    At  August  31,  1996,  the  Company  had  twenty-five  full-time employees,
including six employees in research  and development, nine in manufacturing  and
support services, three in sales and marketing
    
 
                                       28

and  seven  employees  in  administration and  finance.  None  of  the Company's
employees are party to a  collective bargaining agreement. The Company  believes
its relations with its employees are satisfactory.
    
 
FACILITIES
 
    The  Company  occupies  12,900  square feet  within  a  133,000  square foot
multi-tenant facility in Boulder, Colorado,  where it performs all  development,
manufacturing,  marketing  and corporate  activities. The  base rent  payment is
approximately $9,200 per month for 1996,  $9,700 per month for 1997 and  $10,200
per  month for  1998. In addition  to base  rent, the Company  pays its pro-rata
share of building operating expenses, insurance and taxes and its own utilities.
The Company believes the present facility will provide adequate space during the
remaining term of the lease, which expires in January 1999.

(1)  On  June 23, 1995, Mr. Ray was  granted an option to purchase 40,000 shares
     of Common Stock at the  exercise price of $1.25  per share. Such option  is
     subject  to a three-year  vesting period and  will thus be  fully vested on
     June 22,  1998. See  "Management--Employment Agreements."  At the  time  of
     grant,  the fair market value of the  option was determined by the Board of
     Directors to be $1.25 per share.
    
 
1994 STOCK OPTION PLAN
 
   
    In March 1994, the Board of Directors of the Company and, in November  1994,
the  shareholders of  the Company  adopted the Plan.  The Plan  provides for the
grant of options to purchase up to 640,000 shares of Common Stock to  employees,
directors and consultants of the Company. Options may be either "incentive stock
options" within the meaning of Section 422 of the United States Internal Revenue
Code of 1986, as amended (the "Code"), or non-qualified stock options. Incentive
stock   options  may  be  granted  only  to  employees  of  the  Company,  while
non-qualified  stock  options  may  be  issued  to  non-employee  directors  and
consultants, as well as to employees of the Company.
    
 
   
    The  Plan will be administered  by the Board of  Directors or a committee of
the Board made up of non-employee directors (as defined by Rule 16b-3 under  the
Exchange  Act), who  determine, among  other things,  the individuals  who shall
receive options, the time  period during which the  options may be partially  or
fully exercised, the number of shares of Common Stock issuable upon the exercise
of each option, and the option exercise price.
    
 
   
    The  exercise price per share of Common  Stock subject to an incentive stock
option may not be less than the fair  market value per share of Common Stock  on
the  date the option  is granted. The  exercise price per  share of Common Stock
subject to a non-qualified  stock option may  not be less than  85% of the  fair
market  value per share of  Common Stock on the date  the option is granted. The
aggregate fair market value (determined as of the date the option is granted) of
Common Stock for which any person  may be granted incentive stock options  which
first become exercisable in any calendar year may not exceed $100,000. No person
who  owns, directly or indirectly,  at the time of  the granting of an incentive
stock option to such person, 10% or  more of the total combined voting power  of
all  classes of stock of the Company  (a "10% Stockholder") shall be eligible to
receive any incentive stock options under the Plan unless the exercise price  is
at  least 110% of the fair market value of the shares of Common Stock subject to
the option, determined on the date of grant. Non-qualified stock options are not
subject to such limitation.
    
 
   
    No stock option may be transferred by an optionee other than by will or  the
laws  of descent and distribution, and, during  the lifetime of an optionee, the
option will be exercisable only by the optionee, unless otherwise determined  by
the  Board of Directors or committee. In  the event of termination of employment
other than by death  or disability, the  optionee will have  no more than  three
months  after such  termination during which  the optionee shall  be entitled to
exercise the option, unless  otherwise determined by the  Board of Directors  or
committee.  Upon termination of employment of an  optionee by reason of death or
disability, such optionee's options remain  exercisable for one year  thereafter
to  the extent such  options were exercisable  on the date  of such termination,
unless otherwise determined by the Board of Directors or committee.
    
 
    Options under the Plan  must be issued within  ten years from the  effective
date  of the  Plan. The  effective date  of the  Plan is  March 15,  1994. Stock
options granted under the Plan cannot be exercised more than ten years from  the
date  of  grant.  Incentive  stock  options  issued  to  a  10%  Stockholder are
 
                                       33
<PAGE>
   
limited to  five-year terms.  Options granted  under the  Plan provide  for  the
payment  of the  exercise price in  cash or, with  the approval of  the Board of
Directors or  committee,  provide for  the  payment  of the  exercise  price  by
delivery  to the Company of shares of Common Stock already owned by the optionee
having a fair  market value equal  to the  exercise price of  the options  being
exercised. Therefore, such optionee may be able to tender shares of Common Stock
to purchase additional shares of Common Stock and may theoretically exercise all
of  his stock options with  no additional investment other  than the purchase of
his original shares.
    
 
    Any unexercised options  that expire  or that terminate  upon an  employee's
ceasing  to be employed by the Company become available again for issuance under
the Plan.
 
   
    To date, options to acquire 620,397 shares of Common Stock have been granted
under the Plan.  Of such options,  options to acquire  169,598 shares of  Common
Stock  are  exercisable at  an exercise  price  of $1.24  per share,  options to
acquire 80,960 shares of  Common Stock are exercisable  at an exercise price  of
$1.67  per  share,  options  to  acquire  303,039  shares  of  Common  Stock are
exercisable at  an exercise  price of  $1.25 per  share and  options to  acquire
66,800  shares of Common Stock are exercisable at an exercise price equal to the
initial public offering price per share.
    
 
   
1997 STOCK OPTION PLAN
    
 
   
    The Company anticipates requesting its shareholders to approve a 1997  Stock
Option  Plan during  calendar year 1997.  Under the  Underwriting Agreement, the
Company may grant  options to purchase  up to 164,644  additional shares of  its
Common Stock (and a greater amount with the Representative's consent) during the
18 months after the date of this Prospectus. See "Underwriting".
    
 
401(K) PLAN
 
    In  June  1996, the  Company adopted  a  tax-qualified employee  savings and
retirement plan (the  "401(k) Plan")  covering all of  the Company's  employees.
Pursuant to the 401(k) Plan, employees who have been employed by the Company for
at least one year may elect to reduce their current compensation by an amount up
to  the  annual statutory  limit ($9,500  in 1996)  and have  the amount  of the
reduction contributed to the 401(k) Plan.  The Company may also make  additional
discretionary  employer contributions to the 401(k)  Plan. The trustee under the
401(k) Plan invests the assets of the  401(k) Plan in any of several  investment
options. The 401(k) Plan is intended to qualify under Section 401 of the Code so
that  contributions by the  employees to the  401(k) Plan, and  income earned on
plan contributions, are not  taxable to employees until  withdrawn, and so  that
the  contributions  by employees  will be  deductible from  gross income  by the
Company when made. Any Company contributions vest at a rate of 20% per year from
the employee's date of employment through the fifth anniversary thereof.

     options  shown. The fair market value of the Common Stock as of the date of
     grant, June 23,  1995, was  determined to be  $1.25 per  share. The  Common

EMPLOYMENT AGREEMENTS
 
   
    Paul  L. Ray, Chief Executive Officer and Chairman of the Board of Directors
of the  Company, has  an employment  agreement (the  "Ray Agreement")  with  the
Company  that  terminates on  December  31, 1998.  Mr.  Ray's current  salary is
$125,000. Mr.  Ray's compensation  package (including  salary, bonus  and  stock
options  and/or other equity incentives)  is subject to an  annual review by the
Board of Directors, but no portion of such compensation package can be decreased
without Mr.  Ray's  written consent.  Pursuant  to the  Ray  Agreement,  options
granted  to Mr. Ray by virtue of option agreements with the Company shall expire
seven years  from the  date of  grant and  remain exercisable  for a  seven-year
period  regardless of whether  Mr. Ray's employment  with the Company terminates
earlier and  notwithstanding  contrary  provisions in  said  option  agreements.
Options  not vested  on Mr. Ray's  termination of employment  shall be forfeited
unless the Board of  Directors decides otherwise.  In the event  of a Change  in
Control of the Company (as defined in the Ray Agreement), all options previously
granted  to Mr. Ray  which remain unvested  will automatically vest immediately.
Upon a termination of Mr. Ray's employment following a Change in Control, unless
Mr. Ray  voluntarily terminates  his employment  for other  than certain  listed
reasons  (which he has the right to do  upon at least thirty days written notice
to the Company), the Company is to pay  Mr. Ray a lump sum severance payment  of
one-half of his then current annual salary. In addition, if Mr. Ray's employment
is  terminated (i) upon his death, (ii)  by the Company due to various described
disability circumstances, (iii) by the Company without cause or (iv) by Mr.  Ray
voluntarily  upon the Company's  default or unremedied  Adverse Change in Duties
(as defined in the Ray Agreement), then the Company is to pay Mr. Ray a lump sum
severance payment  of one-half  of  his then  current  annual salary.  Upon  the
termination  of  Ray's Agreement,  Mr. Ray  is  subject to  certain non-compete,
non-disturbance and non-interference provisions for a period of six months.

LIMITATION OF LIABILITY AND INDEMNIFICATION
    
 
   
    The Company's Articles of Incorporation limit the liability of a director of
the Company to the Company and its shareholders for monetary damages for  breach
of  fiduciary  duty to  the fullest  extent permitted  by the  Colorado Business
Corporation Act ("CBCA"). The CBCA  permits elimination of a directors  personal
liability  for monetary  damages for  breach of  fiduciary duty,  except (i) for
breach of the director's duty, of loyalty to a company or its shareholders, (ii)
for acts or omissions not in good faith or which involve intentional  misconduct
or  a knowing  violation of law,  (iii) for acts  specified in Section7-108-403,
CBCA and (iv)  for transactions  in which  the director  directly or  indirectly
derived an improper personal benefit.
    
 
   
    The  Company's By-Laws provide that the Company shall indemnify its officers
and directors to the fullest extent permitted by the CBCA, as amended from  time
to time. Subject to several exceptions, the CBCA provides in part that a company
shall  have the power to  indemnify any person made a  party to a proceeding (as
defined in the CBCA) because such person is or was a director or officer of  the
company  or  is or  was serving  at  the company's  request in  a representative
capacity for  another  person  or  entity  against  liability  incurred  in  the
proceeding  if the person conducted  himself or herself in  good faith, and such
person reasonably believed, in the case of conduct in an official capacity, that
his or her conduct was in the  company's best interests and in all other  cases,
that  his  or  her  conduct was  at  least  not opposed  to  the  company's best
interests. In addition, a company is authorized to advance expenses to  officers
and  directors  provided the  officer  or director  furnishes  to the  company a
written affirmation of his or her good faith  belief that he or she has met  the
standard  of conduct  described above and  the officer or  director provides the
company with a  written undertaking  to repay the  advance if  it is  ultimately
determined  that  he  or  she  did  not  meet  such  standard  of  conduct.  Any
indemnification may be  made only as  authorized in each  specific case after  a
determination  has been made that indemnification is permissible by the board of
directors,  a  committee  of  the  board  of  directors,  the  shareholders   or
independent  legal counsel as provided in the CBCA. Where an officer or director
is wholly  successful,  on  the merits  or  otherwise,  in the  defense  of  any
proceeding,  a company  must indemnify  him or  her against  reasonable expenses
incurred. The Company also maintains directors' and officers' liability coverage
to insure indemnification of its directors and officers.
    
 
    Insofar as indemnification for liabilities arising under the Securities  Act
may  be permitted to directors, officers  and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the  opinion of the  Commission such indemnification  is against  public
policy as expressed in the Securities Act and is, therefore, unenforceable.

                              CERTAIN TRANSACTIONS
 
    Ray  L. Hauser, a  shareholder and member  of the Board  of Directors of the
Company, is an owner  of the facility  that was leased by  the Company until  it
moved  into its current office  space in February 1996.  Rent expense under such
lease was $21,645 in 1994 and $48,604 in 1995.
 
   
    During 1995,  the  Company  issued  a series  of  short-term  notes  in  the
aggregate principal amount of $775,000 for working capital. These were issued to
five  of the Company's  existing shareholders and  one director (the "Lenders").
Each Lender also received warrants ("Warrants") to purchase one share of  Common
Stock  at an exercise price of $1.25 per share (and expiring at various times in
the year 2000)  for each  $2.50 loaned  to the  Company as  a term  of the  loan
transaction.  Each note  accrues interest at  the rate  of 11% per  annum and is
secured by  the Company's  current and  future inventory,  accounts  receivable,
intangible  assets and intellectual  property. The Company  intends to repay the
principal amount  of, and  accrued and  unpaid interest  on, such  notes with  a
portion  of the proceeds of this offering.  See "Use of Proceeds." The following
table sets forth each Lender's name, his or its relationship to the Company, the
original principal  amount  of each  note,  the  number of  warrants  issued  in
connection with the issuance of such note, and the amount of interest accrued on
such  note as of June  30, 1996. With the exception  of the Warrants to purchase
40,000 shares of Common Stock held  by Mr. Hamilton, (which expire with  respect
to  20,000 shares on April  6, 2000 and the balance  of 20,000 shares on October
19, 2000), all of the other Warrants  issued to the Lenders have been  exercised
in full.

favorable to the Company as those then available in the marketplace. The Company

obtained from unaffiliated third parties and  will be approved by a majority  of
the independent, disinterested directors of the Company.

    The  authorized  capital stock  of the  Company  consists of  (i) 10,000,000
shares of Common  Stock and  (ii) 2,416,668 shares  of Preferred  Stock, no  par
value  (after  giving effect  to the  mandatory conversion  of 83,332  shares of
Preferred Stock into 304,290 shares of  Common Stock effective upon the  closing
of  this offering; the  "Preferred Stock"). The discussions  of the Common Stock
and Preferred Stock here and elsewhere in this Prospectus are qualified in their
entirety by reference to (i) the Restated and Amended Articles of  Incorporation
of  the Company, as amended, a copy of which has been filed as an exhibit to the
Registration Statement  of  which  this  Prospectus is  a  part,  and  (ii)  the
applicable provisions of the laws of the State of Colorado.
    
 
COMMON STOCK
 
   
    Immediately  prior  to the  closing of  this  offering, 1,667,741  shares of
Common Stock  were  issued  and  outstanding  and were  held  of  record  by  50
shareholders  (after giving effect to the  mandatory conversion of 83,332 shares
of Series A Preferred Stock into  304,290 shares of Common Stock effective  upon
the  closing of this offering). Holders of Common Stock are entitled to one vote
for each share held of record on each matter submitted to a vote of shareholders
and do not have cumulative voting  rights in the election of directors.  Subject
to  the preferences that  may be applicable to  any outstanding Preferred Stock,
the holders of Common Stock are entitled  to receive such dividends, if any,  as
may  be declared from  time to time by  the Board of Directors.  In the event of
liquidation, dissolution or  winding up of  the Company, the  holders of  Common
Stock are entitled to share ratably in all assets of the Company remaining after
payment  of liabilities,  subject to  distribution preferences  of the Preferred
Stock, if  any,  then  outstanding.  The  Common  Stock  has  no  preemptive  or
conversion  rights  or other  subscription rights.  There  are no  redemption or
sinking fund provisions applicable to  the Common Stock. All outstanding  shares
of  Common Stock and the shares of Common  Stock to be issued upon completion of
this offering  will  be validly  authorized  and  issued, fully  paid  and  non-
assessable.  The rights, preferences  and privileges of  holders of Common Stock
are subject to the rights  of the holders of shares  of any series of  Preferred
Stock which the Company may issue in the future.
    
 
PREFERRED STOCK
 
    Upon  the closing of this offering, the  Company will be authorized to issue
up to 2,416,668 shares of Preferred Stock.  At the closing of this offering,  no
shares of Preferred Stock will be issued and outstanding. The Board of Directors
has the authority to issue the Preferred Stock in one or more series, to fix the
number  of shares  constituting each  such series  and the  designations thereof
(including the right to increase or decrease such numbers of shares), and to fix
the  rights,  preferences,  privileges  and  restrictions  thereof,  within  the
limitations  of the CBCA, as such act may be amended, including, but not limited
to, dividend  rights,  dividend  rates, conversion  rights,  redemption  rights,
voting  rights and liquidation preferences. The  issuance of Preferred Stock may
have the effect of delaying, deferring or preventing a change in control of  the
Company  without further action by the shareholders and may adversely affect the
voting and other  rights of the  holders of  Common Stock, The  issuance of  the
Preferred  Stock  with voting  and conversion  rights  may adversely  affect the
voting power  of the  holders of  Common  Stock, including  the loss  of  voting
control  to others. At present, the Company has no plans to issue any additional
Preferred Stock.  See  "Risk Factors--Preferred  Stock;  Possible  Anti-Takeover
Effects."
 
WARRANTS
 
   
    Immediately  prior to  the closing of  this offering, the  Company will have
outstanding warrants  to  purchase 40,000  shares  of  the Common  Stock  at  an
exercise  price of $1.25 per share. In  lieu of delivering the exercise price in
cash or by check, the holder may elect  to receive shares equal to the value  of
the  warrant or  portion thereof  being exercised.  Holders of  the warrants are
entitled to  advance notice  of certain  dividends and  distributions,  proposed
liquidation,  merger or consolidation and benefit from anti-dilution protection.
Holders  of  warrants  are  entitled  to  the  piggyback  rights  described   in
"Description of Securities--Registration Rights."

REGISTRATION RIGHTS
 
   
    The  holders of 574,291 shares of Common Stock and the holder of warrants to
purchase 40,000 shares  of Common  Stock will  be entitled  to the  registration
rights  described below with respect to such shares, subject to the terms of the
lock-up agreements described elsewhere in this Prospectus. See "Shares  Eligible
For  Future Sale" and "Underwriting." Under the terms of the Registration Rights
Agreement, dated as of July 8, 1994, between the Company and the holders of  its
Series  A  Preferred Stock  ("Registration  Rights Agreement"),  if  the Company
proposes at  any time  after 12  months after  the date  of this  Prospectus  to
register  any of its shares under the  Securities Act either for its own account
or for the account of other shareholders, such holders are entitled to notice of
such registration  and  are  entitled  to  include  in  such  registration  (the
"Piggyback Rights"), their 304,290 shares of Common Stock received on conversion
of  their  Series A  Preferred  Stock. Such  shareholders  may also  require the
Company, by request of  the holders of a  majority of the aggregate  outstanding
registrable  securities, on one and only one  occasion after 12 months after the
effective date of  this offering,  to file  a registration  statement under  the
Securities  Act at the Company's  expense with respect to  such shares of Common
Stock, and  the Company  is required  to use  its best  efforts to  effect  such
registration.  In  addition,  holders  of (i)  270,000  shares  of  Common Stock
acquired pursuant to the exercise of  warrants and (ii) outstanding warrants  to
purchase 40,000 shares of Common Stock have the Piggyback Rights described above
with  respect  to such  shares.  The above  registration  rights granted  to the
holders of  the  Series  A Preferred  Stock  expire  on July  7,  1999  and  the
registration  rights granted to the holders of  the warrants expire on March 15,
2000, unless in each case expiring sooner  as a result of such securities  being
eligible  for  resale  pursuant  to  the provisions  of  Rule  144(k)  under the
Securities Act  (so long  as  the holder  owns less  than  3% of  the  Company's
outstanding Common Stock).
    
 
TRANSFER AGENT AND REGISTRAR
 
    The  Transfer Agent  and Registrar  for the  Common Stock  is American Stock

RECAPITALIZATION
    
 
   
    On September  6, 1996,  the Board  of  Directors approved  a four  for  five
reverse  stock split of the Common Stock.  The proposed reverse stock split will
be submitted  for  shareholder approval  at  a special  meeting  to be  held  on
September 23, 1996.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon  completion of this offering, the Company will have 2,867,741 shares of
Common Stock outstanding (3,047,741  shares of Common  Stock outstanding if  the
Representative's  over-allotment option is exercised  in full). Of these shares,
the 1,200,000 Shares  offered hereby (1,380,000  shares if the  Representative's
over-allotment  option is  exercised in full)  will be  freely tradeable without
further registration under the Securities  Act. The Representative is  requiring
the holders of all the Common Stock outstanding and the option holders under the
Plan  and the holder of the warrants (to purchase 40,000 shares of Common Stock)
(i) to agree not to publicly sell, or otherwise dispose of, any shares of Common
Stock or shares of  Common Stock issuable upon  exercise of options or  warrants
for  a  period  of  18  months  from  the  date  of  this  offering  without the
Representative's prior written consent and (ii)  to agree not to privately  sell
or  otherwise dispose of any such shares  during such period unless the proposed
transferee agrees to be bound by such restrictions on transfer.
    
 
   
    All of  the 1,667,741  shares  of Common  Stock  outstanding prior  to  this
offering  are  "restricted securities"  within the  meaning of  Rule 144  of the
Securities Act and, if held for at  least two years, would be eligible for  sale
in the public market in reliance upon, and in accordance with, the provisions of
Rule  144 following  the expiration  of such two-year  period. As  of August 31,
1996, 1,327,588 shares of Common Stock had been held for at least two years.  In
general, under Rule 144 as currently in effect, a person or persons whose shares
are aggregated, including a person who may be deemed to be an "affiliate" of the
Company as that term is defined under the Securities Act (an "Affiliate"), would
be   entitled  to  sell  within  any  three-month  period  a  number  of  shares
beneficially owned for at least  two years that does  not exceed the greater  of
(i)  1% of  the then  outstanding shares  of Common  Stock, or  (ii) the average
weekly trading  volume  in the  Common  Stock  during the  four  calendar  weeks
preceding  such  sale.  Sales  under  Rule  144  are  also  subject  to  certain
requirements as to the  manner of sale, notice  and the availability of  current
public  information about the  Company. However, a  person who is  not deemed to
have been an affiliate  of the Company  during the 90 days  preceding a sale  by
such  person and who has beneficially owned  shares of Common Stock for at least
three years may sell such shares without regard to the volume, manner of sale or
notice requirements  of  Rule  144.  The Commission  has  recently  proposed  an
amendment  to Rule 144 which would reduce  the holding period for shares subject
to Rule 144 to become eligible for sale in the public market.
    
 
   
    Rule 701 under the Securities Act  provides that the shares of Common  Stock
acquired on the exercise of options granted under a written compensatory plan of
the  Company or contract with  the Company prior to  the date of this Prospectus
may be resold  by persons, other  than Affiliates, beginning  90 days after  the
date  of this Prospectus, subject only to  the manner of sale provisions of Rule
144, and  by Affiliates  under Rule  144 without  compliance with  its  two-year
minimum  holding period, subject to certain limitations. There are 13,328 shares
of Common Stock outstanding from prior exercises of options granted pursuant  to
option  contracts  with  the Company  and  620,397  shares of  Common  Stock are
issuable upon the exercise of outstanding options under the Plan  (collectively,
the  "Option Shares"). Beginning 90 days after  the date of this Prospectus, all
of the Option Shares would be eligible for sale in reliance on Rule 701, subject
to certain  vesting provisions.  In  addition, the  Company  intends to  file  a
registration statement on Form S-8 to permit the shares of Common Stock acquired
upon exercise of the options to be freely tradeable or sold.
    
 
    Prior  to this offering, there  has been no public  market for the Company's
securities. Following this offering, the  Company cannot predict the effect,  if
any,  that sales of shares of Common Stock pursuant to Rule 144 or otherwise, or
the availability  of  such  shares for  sale,  will  have on  the  market  price
prevailing from time to time. Nevertheless, sales by the current shareholders of
a  substantial  number of  shares of  Common  Stock in  the public  market could
materially adversely affect prevailing  market prices for  the Common Stock.  In
addition,  the availability for sale of a substantial number of shares of Common
Stock acquired  through the  exercise of  the Representative's  Warrants or  the
currently  outstanding options under  the Plan or  the outstanding warrant could
materially adversely affect prevailing market  prices for the Common Stock.  See
"Risk Factors--Shares Eligible For Future Sale."

    Up  to 120,000  additional shares  of Common Stock  may be  purchased by the
Representative during the period commencing on the first anniversary of the date
of this Prospectus and terminating on the fifth anniversary of the date of  this
Prospectus  through the exercise  of the Representative's  Warrants. Any and all
shares of  Common Stock  purchased  upon the  exercise of  the  Representative's
Warrants  may be freely  tradeable, provided that  the Company satisfies certain
securities registration and  qualification requirements in  accordance with  the
terms of the Representative's Warrants. See "Underwriting."
 
   
    After  the offering, the holders of 574,291 shares of Common Stock, or their
transferees, will be entitled to certain rights with respect to the registration
of   such   shares   under   the    Securities   Act.   See   "Description    of
Securities--Registration   Rights."  Registration  of   such  shares  under  the
Securities Act would  result in  such shares becoming  freely tradeable  without
restriction under the Securities Act (except for shares purchased by Affiliates)
immediately upon the effectiveness of such registration.

    A copy of the  Underwriting Agreement has  been filed as  an exhibit to  the
Registration  Statement,  to which  reference is  hereby made.  The Underwriting
Agreement provides  that the  obligations  of the  Underwriters are  subject  to
certain  conditions. The Underwriters shall be  obligated to purchase all of the
shares of Common Stock offered hereby if any are purchased.
 
    Through the Representative, the Underwriters  have advised the Company  that
they propose to offer the shares of Common Stock offered hereby to the public at
the  public offering price  set forth on  the cover page  of this Prospectus and
that they  may  allow  to  certain  dealers who  are  members  of  the  National
Association  of Securities  Dealers, Inc. (the  "NASD"), and  to certain foreign
dealers, concessions not in excess of  $       per share, of which amount a  sum
not  in excess of $       per share may in  turn be reallowed by such dealers to
other dealers who are members of the NASD and to certain foreign dealers.  After
the  commencement of this offering, the  concessions and the reallowances may be
changed by the Representative.
 
    The Company  has  agreed  to  indemnify  the  Underwriters  against  certain
liabilities,  including liabilities under the  Securities Act, and to contribute
to payments the Underwriters may be required to make in respect thereof.
 
    The Company has  agreed to pay  to the Representative  an aggregate  expense
allowance, on a non-accountable basis, equal to 3% of the gross proceeds derived
from  the sale of 1,200,000 shares of  Common Stock offered hereby (or 1,380,000
shares of Common Stock if Representative's over-allotment option is exercised in
full). The Company paid an advance on such allowances in the amount of  $50,000.
The  Company has also agreed to pay  certain of the Representative's expenses in
connection with this offering, including expenses in connection with  qualifying
the  shares  of Common  Stock for  sale under  the  laws of  such states  as the
Representative may  designate.  In  addition,  the  Company  will  sell  to  the
Representative,  at an  aggregate purchase  price of  $120, the Representative's
Warrants to  purchase up  to an  aggregate  of 120,000  shares of  Common  Stock
exercisable  at a price per  share equal to 110%  of the initial public offering
price per Share.
 
   
    The Representative  is  requiring  the  holders  of  all  the  Common  Stock
outstanding and the option holders under the Plan and the holder of the warrants
(to  purchase 40,000 shares of Common Stock)  (i) to agree not to publicly sell,
or otherwise dispose of, any  shares of Common Stock  or shares of Common  Stock
issuable upon exercise of options or warrants for a period of 18 months from the
date  of this  offering without the  Representative's prior  written consent and
(ii) to agree  not to privately  sell or  otherwise dispose of  any such  shares
during  such period unless  the proposed transferee  agrees to be  bound by such
restrictions on transfer. In addition, for a period of 18 months after the  date
of  this Prospectus, the  Company has agreed  that, without the Representative's
prior consent (which shall
    
 
                                       44
<PAGE>
   
not be unreasonably withheld), it  will not sell any  shares of Common Stock  or
grant  any  options or  warrants to  purchase  Common Stock  other than  (i) the
Representative's Warrants, (ii) options which may be granted under the Plan  and
up  to  164,644  additional options,  (iii)  shares  of Common  Stock  issued in
connection with the  exercise of any  such options or  warrants, (iv) shares  of
Common Stock issued upon the exercise of options and warrants outstanding on the
date  hereof  and  (v) shares  of  Common  Stock issued  in  connection  with an
acquisition by the Company.
    
 
    Prior to  this offering,  there has  been no  public market  for the  Common
Stock.  The initial public offering price of the shares of Common Stock has been
determined by negotiation between the Company and the Representative. Among  the
factors  considered in such negotiations were (i) an assessment of the Company's
future prospects, (ii)  the experience  of the Company's  management, (iii)  the
current financial position of the Company, (iv) the prevailing conditions in the
securities  markets, including  the market value  of the  publicly traded common
stock of companies  in similar  industries, (v)  the market  conditions for  new
offerings of securities and (vi) the demand for similar securities of comparable
companies.
 
OVER-ALLOTMENT OPTION
 
    The  Company has granted to the Representative an option, exercisable in the
sole discretion of  the Representative  within 45 days  after the  date of  this
Prospectus,  to purchase up  to an aggregate  of 180,000 shares  of Common Stock
solely to cover  over-allotments, if any.  Such options are  exercisable at  the
public  offering price  per share  less underwriting  discounts and commissions.
After the commencement of this offering, the Representative may confirm sales of
shares of  Common Stock  subject  to this  over-allotment option.  Purchases  of
shares of Common Stock upon exercise of the over-allotment option will result in
the realization of additional compensation by the Representative.
 
REPRESENTATIVE'S WARRANTS
 
   
    In  connection with  this offering,  the Company has  agreed to  sell to the
Representative, individually  and  not  as the  Representative  of  the  several
underwriters,  for  an aggregate  purchase price  of $120,  the Representative's
Warrants to purchase up to 120,000 shares of Common Stock. The  Representative's
Warrants are exercisable for a period of four years commencing one year from the
date  hereof at an exercise price per share (the "Exercise Price") equal to 110%
of the initial public  offering price per  share. The Representative's  Warrants
may  not be sold, transferred, assigned, pledged or hypothecated for a period of
12 months from  the date of  the Prospectus,  except to members  of the  selling
group and officers and partners of the Representative and members of the selling
group.  The Representative's Warrants contain anti-dilution provisions providing
for adjustment of the Exercise  Price and the number  of shares of Common  Stock
issuable  upon  the  exercise thereof  upon  the occurrence  of  certain events,
including stock dividends, stock splits,  recapitalizations and sales of  Common
Stock  below the then current market price  (as defined therein). The holders of
the Representative's  Warrants  have no  voting,  dividend or  other  rights  as
shareholders  of the Company  with respect to shares  of Common Stock underlying
the Representative's Warrants,  unless the Representative's  Warrants have  been
exercised.
    
 
    The Company has agreed, on one occasion during the period beginning one year
after  the date  hereof and  ending four years  thereafter, if  requested by the
holders of a  majority of the  Representative's Warrants or  Warrant Shares,  to
make all necessary filings to permit a public offering of the Warrant Shares and
to  use its  best efforts  to cause  such filing  to become  effective under the
Securities Act  and  to  remain effective  for  at  least nine  months,  at  the
Company's sole expense. Notwithstanding the foregoing, the Company shall have no
obligation to prepare and file such new registration statement or post-effective
amendment to the registration statement if, within 20 days after it receives the
request  therefor, the Company or insiders who  own individually in excess of 5%
of the Common Stock agree to  purchase the Representative's Warrants and/or  the
underlying  securities from such requesting  holders at a price,  in the case of
the Representative's  Warrants, equal  to the  difference between  the  exercise
price  of the Representative's Warrants and the current market price (as defined
therein) of the  Warrant Shares. In  addition, the Company  has agreed, for  the
period
 
                                       45
<PAGE>
starting  at the beginning of  the second year and concluding  at the end of the
fifth year after the effective date of the Registration Statement of which  this
Prospectus  is a part, to give advance notice to holders of the Representative's
Warrants and Warrant Shares of its  intention to file a registration  statement,
and  in  such case,  holders of  the Representative's  Warrants and  the Warrant
Shares shall have the right to require the Company to include the Warrant Shares
in such registration statement at the Company's expense.
 
    During the period  that the Representative's  Warrants are exercisable,  the
Representative  and any  transferee will have  the opportunity to  profit from a
rise in the market price  of the Common Stock with  a resulting dilution in  the
interest of other shareholders. In addition, the terms on which the Company will
be able to obtain additional capital during the exercise period may be adversely
affected  since the  Representative is  likely to  exercise the Representative's
Warrants at a time when the Company would, in all likelihood, be able to  obtain
capital  by a  new offering  of securities  on terms  more favorable  than those
provided by the terms of the Representative's Warrants.
 
   
OBSERVER OF THE BOARD
    
 
   
    In connection with this offering, the Company has agreed that, for the three
year period commencing on  the date of this  Prospectus, the Representative  has
the  right to appoint a designee as an observer at all meetings of the Company's
Board of Directors. This designee  has the right to  attend all meetings of  the
Board  of  Directors and  shall  be entitled  to  receive reimbursement  for all
out-of-pocket expenses  of  attendance  at  such  meetings.  In  addition,  such
designee  shall be indemnified and  insured to the same  extent as the Company's
directors.
    
 
                                 LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for  the
Company  by Ireland, Stapleton, Pryor &  Pascoe, P.C., Denver, Colorado. Certain
legal matters will be passed upon  for the Underwriters by Brock,  Fensterstock,
Silverstein, McAuliffe & Wade, LLC, New York, New York.
 
                                    EXPERTS
 
    The  financial statements as of December 31,  1994 and 1995, and for each of
the two years in the period ended December 31, 1995, included in this Prospectus
have been  so  included in  reliance  on the  report  of Price  Waterhouse  LLP,
independent  accountants,  given on  the authority  of said  firm as  experts in
auditing and accounting.
 
    The statements with respect to the SLU Patent, and the statements  regarding
infringement  with respect  thereto, included  in this  Prospectus have  been so
included in  reliance on  Nikaido,  Marmelstein, Murray  &  Oram, given  on  the
authority of said firm as experts in patent law.
 
                       CHANGE IN INDEPENDENT ACCOUNTANTS
 
    On  November 17, 1994, the Company  dismissed its then current auditors and,
on November 28, 1994, the Company retained Price Waterhouse LLP as the Company's
independent accountants. Such actions  were approved by  the Company's Board  of
Directors. The former auditors' report on the Company's financial statements for
the  two years ended December 31, 1993,  does not cover the financial statements
of the Company included in this Prospectus. The former auditors' report was  not
modified  as  to  audit  scope  or accounting  principles,  but  did  contain an
explanatory paragraph relating to the Company's  ability to continue as a  going
concern.  There were no disagreements with the  former auditors on any matter of
accounting principles or practices,  financial statement disclosure or  auditing
scope  or procedure at the  time of the change or  with respect to the Company's
financial statements for either  of the two years  in the period ended  December
31,  1993, which,  if not resolved  to the former  auditors' satisfaction, would
have caused them to make reference to the subject matter of the disagreement  in
connection  with  their report.  Prior to  retaining  Price Waterhouse  LLP, the
Company had  no consultations  with  Price Waterhouse  LLP regarding  the  audit
reports of the former auditors or application of accounting principles.

 of Image Guided Technologies, Inc.
    
 
   
    The  reverse  stock split  described in  third  paragraph of  Note 9  to the
financial statements has not been consummated at September 6, 1996. When it  has
been consummated, we will be in a position to furnish the following report:
    
 
   
    "In  our opinion, the accompanying balance  sheet and the related statements
    of operations,  of changes  in shareholders'  equity (deficit)  and of  cash
    flows  present fairly, in  all material respects,  the financial position of
    Image Guided Technologies,  Inc. (the  "Company") at December  31, 1994  and
    1995,  and the results of its operations and  its cash flows for each of the
    two years in the period ended December 31, 1995 in conformity with generally
    accepted  accounting  principles.   These  financial   statements  are   the
    responsibility of the Company's management; our responsibility is to express
    an  opinion on these financial statements  based on our audits. We conducted
    our audits  of  these  statements  in  accordance  with  generally  accepted
    auditing  standards which  require that  we plan  and perform  the audits to
    obtain reasonable assurance about whether the financial statements are  free
    of  material misstatement.  An audit  includes examining,  on a  test basis,
    evidence supporting the amounts and disclosures in the financial statements,
    assessing the accounting principles used  and significant estimates made  by
    management,  and evaluating the overall financial statement presentation. We
    believe that our audits provide a reasonable basis for the opinion expressed
    above."

                         NOTES TO FINANCIAL STATEMENTS
 
1.  ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
    Image  Guided Technologies, Inc. (the "Company") was incorporated in 1990 in
the State of Colorado  to design, develop,  manufacture and market  proprietary,
hand-held  electro-optical 3-dimensional position input  devices for medical and
industrial applications.  In  March 1995,  the  Company changed  its  name  from
Pixsys, Inc. to Image Guided Technologies, Inc.
 
REVENUE RECOGNITION AND WARRANTY
 
    Revenue  is recognized upon shipment. The Company offers a one-year warranty
on products sold. The costs of product warranties are accrued at the time  sales
are  recorded based upon estimates of costs  to be incurred to repair or replace
items under warranty.
 
INVENTORIES
 
    Inventories are carried at the lower  of cost or market. Cost is  determined
using the first-in, first-out ("FIFO") method.
 
PROPERTY AND EQUIPMENT
 
   
    Property  and equipment is stated at cost and depreciated on a straight-line
basis over their estimated useful lives of two to five years.
    
 
CASH EQUIVALENTS
 
    The Company  considers  all  highly liquid  investments  purchased  with  an
original  maturity  of  three  months  or  less  to  be  cash  equivalents. Cash
equivalents are carried at cost which approximates fair value.
 
USE OF ESTIMATES
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that affect the reported  amounts of certain assets and  liabilities
and disclosure of contingent assets and liabilities at the date of the financial
statements  and the related reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
INTERIM FINANCIAL DATA
 
    The interim financial data as of June 30, 1996 and for the six months  ended
June  30,  1995 and  June  30, 1996  is unaudited;  however,  in the  opinion of
management of the Company, the interim data includes all adjustments, consisting
only of normal recurring adjustments, necessary  for a fair presentation of  the
results  for the interim periods presented. All data presented in these notes at
such date and for such periods is unaudited.
 
UNAUDITED PRO FORMA SHAREHOLDERS' EQUITY
 
   
    The Board  of Directors  authorized  management of  the  Company to  file  a
registration  statement  with  the Securities  and  Exchange  Commission ("SEC")
permitting the Company to sell shares of its common stock to the public. If  the
Company's  initial  public offering  is  consummated under  the  terms presently
anticipated,  all   of  the   convertible  preferred   stock  outstanding   will
automatically  convert into 304,290 shares of  common stock. Unaudited pro forma
shareholders' equity  as of  June 30,  1996, as  set forth  on the  accompanying
balance sheet, is adjusted for the anticipated conversion of preferred stock.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
UNAUDITED PRO FORMA NET INCOME (LOSS) PER COMMON SHARE
 
    The  Company's  historical  capital  structure  is  not  indicative  of  its
prospective structure due to the  automatic conversion of convertible  preferred
stock into common stock concurrent with the closing of the Company's anticipated
initial  public offering. Accordingly,  historical net income  (loss) per common
share is not considered meaningful and has not been presented herein.
 
    Pro forma  net income  (loss) per  common  share is  computed based  on  the
weighted average number of common shares outstanding and gives effect to certain
adjustments  described below. Common  equivalent shares are  not included in the
per share calculation where the effect of their inclusion would be antidilutive,
except that, in conformity with  SEC requirements, common and common  equivalent
shares  issued  during  the  twelve-month  period prior  to  the  filing  of the
Company's proposed initial public offering have been included in the calculation
as if they were outstanding for all periods, using the treasury stock method and
the assumed initial  public offering price  of $5 per  share. Additionally,  all
outstanding  shares  of convertible  preferred stock  are  assumed to  have been
converted to common stock at the time of their issuance.
 
UNAUDITED SUPPLEMENTAL PRO FORMA NET INCOME (LOSS) PER SHARE
 
    Supplemental pro forma net income (loss) per share is based on the  weighted
average  number of shares of  common stock and common  stock equivalents used in
the calculation of  pro forma net  income (loss)  per share plus  the number  of
shares  that would  be required to  be sold, on  a net proceeds  basis, to repay
borrowings outstanding on the Company's notes payable ($775,000 in the aggregate
at June  30, 1996)  as contemplated  in connection  with the  Company's  initial
public offering. For purposes of this calculation, net income has been increased
by  $43,098 for the six-month  period ended June 30, 1996  and net loss has been
reduced by $43,192 for the year ended December 31, 1995, to reflect  elimination
of interest expense on such notes payable.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of the Company's financial instruments, including cash,
short-term  trade receivables and payables and long-term debt, approximate their
fair values.
 
CONCENTRATION OF CREDIT RISK
 
    The majority of the  Company's revenues during 1994  and 1995 resulted  from
sales  of a single product which is used to determine the location of a surgical
instrument in a three dimensional space. Customers accounting for 10% or more of
total revenues during 1994 and 1995 are as follows:

</TABLE>
 
    At December  31, 1994,  17%, 0%  and 29%  of accounts  receivable were  with
customers  A, B, and C,  respectively. At December 31, 1995,  25%, 6% and 60% of
accounts receivable were with customers D, E and F, respectively.
 
EXPORT SALES
 
    The Company had  export sales totaling  approximately $400,247 and  $450,187
for  the years  ended December 31,  1994 and 1995,  respectively, principally to
Germany, France, and Canada.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
ADOPTION OF NEW ACCOUNTING STANDARDS
 
    The Company has  reviewed Statements of  Financial Accounting Standards  No.
121,  ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED  ASSETS TO BE DISPOSED OF, and
No. 123, ACCOUNTING  FOR STOCK-BASED COMPENSATION,  for applicability. Based  on
management's  estimates  and its  intention to  continue  to apply  its existing
accounting for stock options, the adoption of these standards is not expected to
have a material effect on the Company's financial statements.

5.  NOTES PAYABLE
 
    The notes payable at December 31, 1995 and June 30, 1996 (unaudited) consist
of the following:

                                                                           $ 775,000
                                                                           ---------
                                                                           ---------
</TABLE>
 
   
    The Company issued 310,000 warrants to purchase common stock at an  exercise
price  of $1.25  per share pursuant  to each  of the notes  payable above. These
warrants are  fully  vested  and  outstanding  at  December  31,  1995  and  are
exercisable  through 2000. The warrants were  valued in good faith by management
at $131,692 and a corresponding amount  was recorded as debt discount which  was
fully  amortized, over the original  term of the notes  payable, during 1995. Of
these warrants, 270,000 warrants were exercised in May and June of 1996.
    
 
   
    The notes payable are secured by the Company's current and future inventory,
accounts receivable,  intangible  assets  and intellectual  property.  The  fair
market  value of the notes payable approximates their carrying value at December
31, 1995.  Subsequent to  December  31, 1995,  the Company  negotiated  extended
payment terms on the above notes payable. See Note 9.
    
 
6.  INCOME TAXES
 
    At  December 31, 1994,  the Company had net  operating loss carryforwards of
approximately $1,967,000. At December  31, 1995, the  Company has net  operating
loss  carryforwards  of approximately  $2,788,000  which expire  from 2006-2010.
During 1994, certain changes in the Company's ownership occurred which limit the
future utilization of these net  operating loss carryforwards. Future  ownership
changes  may  further  limit the  ability  of  the Company  to  realize  its net
operating loss carryforwards.
 
   
    At December 31, 1994 and 1995, the Company had gross deferred tax assets  of
approximately $792,000 and $1,180,000, respectively, consisting primarily of the
tax  effect of net  operating loss carryforwards. The  gross deferred tax assets
have  been  reduced  by  a  valuation  allowance  of  $792,000  and  $1,180,000,
respectively,  because, based  on the  weight of  available evidence, management
believes it is more likely than not that such benefits will not be realized. The
valuation allowance increased by approximately $383,000 and $388,000 during 1994
and 1995, respectively, primarily  because no benefit  was recorded for  current
year losses.
    
 
    The  difference  between  the  expected  statutory  benefit,  determined  by
applying the federal income tax rate of  34% to loss before income tax, and  the
Company's  tax benefit was primarily the additional valuation allowance recorded
against net operating loss benefits generated during 1994 and 1995. No provision
for income taxes has been recorded during 1996, as the Company has been able  to
utilize net operating loss carryforwards.

7.  SHAREHOLDERS' EQUITY
 
STOCK SPLIT
 
    During  1994,  the  Company  effected  a  four-for-one  stock  split  of the
Company's common stock. All common stock  and stock option amounts presented  in
these financial statements reflect this stock split.
 
CONVERTIBLE PREFERRED STOCK
 
   
    Holders  of  Series A  Convertible Preferred  Stock  ("Series A  stock") are
entitled to receive dividends equal to those paid on the number of common shares
into which  the preferred  shares  are convertible.  Each share  of  outstanding
Series  A stock is entitled to  as many votes as the  number of shares of common
stock into which it is convertible. The  holders of Series A shares may, at  any
time,  convert their preferred shares into common shares on a one-for-one basis,
subject to adjustments for stock splits and certain antidilution provisions.  As
of  December  31,  1995,  such  Series A  shares  outstanding  would  convert to
approximately 304,290 shares of common  stock. All Series A stock  automatically
converts  into common stock at the closing of an underwritten public offering of
common stock of  the Company with  aggregate offering proceeds  of no less  than
$5,000,000  or when  at least  75% of  all outstanding  Series A  stock has been
converted.
    
 
   
    In the event of  a liquidation of  the Company, holders  of Series A  shares
will  be  entitled  to  a  liquidation preference  of  $3.75  per  share, before
adjustment for any future stock splits.
    
 
COMMON STOCK
 
   
    At December 31,  1995, the Company  has reserved an  aggregate of  1,234,454
shares  of its common stock for the conversion of the outstanding Series A stock
and stock issuable upon exercise of outstanding options and warrants.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
   
    The Company's Articles of Incorporation limit the liability of a director of
the  Company to the Company and its shareholders for monetary damages for breach
of fiduciary  duty to  the fullest  extent permitted  by the  Colorado  Business
Corporation  Act ("CBCA"). The CBCA permits  elimination of a directors personal
liability for  monetary damages  for breach  of fiduciary  duty except  (i)  for
breach  of the director's duty of loyalty to a company or its shareholders, (ii)
for acts or omissions not in good faith or which involve intentional  misconduct
or  a knowing  violation of law,  (iii) for acts  specified in Section7-108-403,
CBCA and (iv)  for transactions  in which  the director  directly or  indirectly
derived an improper personal benefit.
    
 
   
    The  Company's By-Laws provide that the Company shall indemnify its officers
and directors to the fullest extent permitted by the CBCA, as amended from  time
to time. Subject to several exceptions, the CBCA provides in part that a company
shall  have the power to  indemnify any person made a  party to a proceeding (as
defined in the CBCA) because such person is or was a director or officer of  the
company  or  is or  was serving  at  the company's  request in  a representative
capacity for  another  person  or  entity  against  liability  incurred  in  the
proceeding  if the person conducted  himself or herself in  good faith, and such
person reasonably believed, in the case of conduct in an official capacity, that
his or her conduct was in the  company's best interests and in all other  cases,
that  his  or  her  conduct was  at  least  not opposed  to  the  company's best
interests. In addition, a company is authorized to advance expenses to  officers
and  directors  provided the  officer  or director  furnishes  to the  company a
written affirmation of his or her good faith  belief that he or she has met  the
standard  of conduct  described above and  the officer or  director provides the
company with a  written undertaking  to repay the  advance if  it is  ultimately
determined  that  he  or  she  did  not  meet  such  standard  of  conduct.  Any
indemnification may be  made only as  authorized in each  specific case after  a
determination  has been made that indemnification is permissible by the board of
directors,  a  committee  of  the  board  of  directors,  the  shareholders   or
independent  legal counsel as provided in the CBCA. Where an officer or director
is wholly  successful,  on  the merits  or  otherwise,  in the  defense  of  any
proceeding,  a company  must indemnify  him or  her against  reasonable expenses
incurred. The Company also maintains directors' and officers' liability coverage
to insure indemnification of its directors and officers.
    
 
   
    Section 8 of the Underwriting Agreement filed as Exhibit 1.1 hereto provides
for the indemnification by the Underwriters of the Registrant and its  directors
and officers, and by the Registrant of the Underwriters, for certain liabilities
arising  under the Securities Act of 1933, as amended (the "Securities Act"), or
otherwise.

ITEM 28.  UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes to provide to the  Underwriters
at  the closing  specified in  the Underwriting  Agreement certificates  in such
denominations and registered in  such names as required  by the Underwriters  to
permit prompt delivery to each purchaser.
 
    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 Securities Act
and  is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the  payment by the Registrant of  expenses
incurred  or paid by a director, officer or controlling person 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 Securities  Act and  will be governed  by the final
adjudication of such issue.
 
    The undersigned Registrant hereby undertakes that:
 
   
    (1) For purposes of  determining any liability under  the Securities Act  of
1933,  the information omitted from the form of prospectus filed as part of this
Registration Statement in  reliance upon Rule  430A and contained  in a form  of
prospectus  filed by the Registrant pursuant to  Rule 424(b)(1) or (4) or 497(h)
under the  Securities  Act shall  be  deemed to  be  part of  this  Registration
Statement as of the time it is declared effective.
    
 
    (2)  For the purpose of determining  any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new Registration Statement  relating to the securities offered  therein,
and  the offering  of such  securities at that  time shall  be deemed  to be the
initial bona fide offering thereof.
 
    (3) It will:
 
        (a) File, during any  period in which it  offers or sells securities,  a
    post-effective amendment to this Registration Statement to:
 
           (i)  Include  any  prospectus  required by  section  10(a)(3)  of the
       Securities Act;
 
           (ii)  Reflect  in   the  prospectus  any   facts  or  events   which,
       individually   or  together,  represent  a   fundamental  change  in  the
       information  in  the  Registration  Statement;  and  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  end  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 the volume  and price represent no more than  a
       20%  change  in the  maximum aggregate  offering price  set forth  in the
       "Calculation of  Registration Fee"  table in  the effective  Registration
       Statement.
 
           (iii)  Include any additional or  changed material information on the
       plan of distribution.
 
        (b) For  determining  liability under  the  Securities Act,  treat  each
    post-effective  amendment as a new  Registration Statement of the securities
    offered, and the offering of the securities  at that time to be the  initial
    bona fide offering.
 
        (c)  File a post-effective amendment to  remove from registration any of
    the securities that remain unsold at the end of the offering.

          Re:  Registration Statement on Form SB-2 (File No. 333-9103)

Ladies and Gentlemen:

          We have acted as counsel to Image Guided Technologies, Inc., a
Colorado corporation (the "Company"), in connection with the preparation and
filing of the above-captioned Registration Statement on Form SB-2 (the
"Registration Statement") under the Securities Act of 1933, as amended (the
"Securities Act"), covering 1,380,000 shares of common stock (the "Common
Stock"), no par value, of the Company, 120,000 warrants (the "Warrants") to
purchase 120,000 shares of Common Stock, and 120,000 shares of Common Stock
underlying such Warrants.

          As such counsel, we have examined such corporate records, certificates
and other documents and such questions of law as we have considered necessary or
appropriate for the purposes of this opinion.  In rendering this opinion, we
have (a) assumed (i) the genuineness of all signatures on all documents examined
by us, (ii) the authenticity of all documents submitted to us as originals, and
(iii) the conformity to original documents of all documents submitted to us as
photostatic or conformed copies and the authenticity of the originals of such
copies; and (b) relied on, as to matters of fact, statements and certificates of
officers of the Company.

          We are attorneys admitted to the Bar of the State of Colorado, and we
express no opinion as to the laws of any other jurisdiction other than the laws
of the United States of America and the Colorado Business Corporation Act.

          Based upon the foregoing, we are of the opinion that:


          1.   When the shares of Common Stock proposed to be issued and sold by
the Company are duly issued, delivered and paid for as set forth in the
Registration Statement, such shares will be legally issued, fully paid and non-
assessable.

          2.   When the Warrants proposed to be issued and sold by the Company
are duly issued, delivered and paid for as set forth in the Registration
Statement, such Warrants will be legally issued, fully paid and non-assessable.

          3.   When the shares of Common Stock underlying the Warrants proposed
to be issued and sold by the Company are duly issued, delivered and paid for as
set forth in the Registration Statement, such shares will be legally issued,
fully paid and non-assessable.

          We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the heading "Legal
Matters" in the Prospectus.  In giving such consent we do not thereby concede
that we are within the category of persons whose consent is required under
Section 7 of the Securities Act or the rules and regulations promulgated
thereunder.


                         Very truly yours,

                         IRELAND, STAPLETON, PRYOR & PASCOE, P.C.

                                1994 STOCK OPTION PLAN


I.  PURPOSE

   
    The IMAGE GUIDED TECHNOLOGIES, INC. 1994 STOCK OPTION PLAN ("Plan") 
provides for the grant of Stock Options to employees, directors and 
consultants of Pixsys, Inc. (the "Company"), and such of its subsidiaries (as 
defined in Section 424(f) of the Internal Revenue Code of 1986 (the "Code") 
as the Board of Directors of the Company shall from time to time designate 
("Participating Subsidiaries") in order to advance the interests of the 
Company and its Participating Subsidiaries through the motivation, attraction 
and retention of key personnel.
    

II. INCENTIVE STOCK OPTIONS AND NON-INCENTIVE STOCK OPTIONS


    The Stock Options granted under the Plan may be either:

         a)   Incentive Stock Options ("ISOs") which are intended to be
"Incentive Stock Options" as that term is defined in Section 422 of the Code; or

         b)   Nonstatutory Stock Options ("NSOs") which are intended to be
options that do not qualify as "Incentive Stock Options" under Section 422 of
the Code.

Subject to the other provisions of the Plan, a Participant may receive ISOs and
NSOs at the same time, provided that the ISOs and NSOs are clearly designated as
such, and the exercise of one does not affect the exercise of the other.

    Except as otherwise expressly provided herein, all of the provisions and
requirements of the Plan relating to Stock Options shall apply to ISOs and NSOs.


III. ADMINISTRATION

   
    The Plan shall be administered by the Board of Directors (the "Board") of
the Company or by a committee of two or more directors ("Committee") appointed 
by the Board, each of whom shall be a "non-employee director" as defined in 
Rule
    

<PAGE>

   
16b-3 under the Securities Exchange Act of 1934,as amended (the "Exchange 
Act").  The Committee or the Board of Directors, as the case may be,shall 
have full authority to administer the Plan, including authority tointerpret 
and construe any provision of the Plan and any Stock Options granted 
thereunder, and to adopt such rules and regulations for administering the 
Plan as it may deem necessary in order to comply with the requirements of the 
Code or in order that Stock Options that are intended to be ISOs will be 
classified as incentive stock options under the Code, or in order to conform 
to any regulation or to any change in any law or regulation applicable 
thereto.
    
   
    All actions taken and all interpretations and determinations made by the
Board or Committee in good faith (including determinations of Fair Market Value)
shall be final and binding upon all Participants, the Company and all other
interested persons.  No member of the Board or Committee shall be personally
liable for any action, determination or interpretation made in good faith with
respect to the Plan, and all members of the Board and Committee shall, in
addition to their rights as directors, be fully protected by the Company with
respect to any such action, determination or interpretation.  Rule 16b-3 under
the Exchange Act provides that the grant of a stock option to a director or
officer of a company will be exempt from the provisions of Section 16(b) of the
Exchange Act if the conditions set forth in said Rule are satisfied.  Unless 
otherwise specified by the Board or Committee, grants of Stock Options 
hereunder to individuals who are officers or directors of the Company shall 
be made in a manner that satisfies the conditions of said Rule.
    

IV.  DEFINITIONS


    4.1  "STOCK OPTION."  A Stock Option is the right granted under the Plan to
an Employee, director, or consultant to purchase at such time or times, on such
terms and at such price or prices ("Option Price") as are determined by the
Board or Committee, the number of shares of Common Stock determined by the Board
or Committee.

    4.2  "COMMON STOCK."  A share of Common Stock means a share of authorized
but unissued or reacquired common stock of the Company.

    4.3  "FAIR MARKET VALUE."  If the Common Stock is traded publicly, the Fair
Market Value of a share of Common Stock on any date shall be the average of the
representative closing bid and asked prices, as quoted by the National
Association of Securities Dealers through NASDAQ (its automated system for
reporting quotes), for the date in question, or, if the Common Stock is


                                         -2-

<PAGE>

listed on the NASDAQ National Market System or is listed on a national stock
exchange, the officially quoted closing price on NASDAQ or such exchange, as the
case may be, on the date in question.  If the Common Stock is not traded
publicly, the Fair Market Value of a share of Common Stock on any date shall be
determined in good faith by the Board of Directors or the Committee after such
consultations with outside legal, accounting and other experts as the Board of
Directors or the Committee may deem advisable.

    4.4  "EMPLOYEE."  An Employee is an employee of the Company or any
Participating Subsidiary.

    4.5  "PARTICIPANT."  A Participant is an Employee, director or consultant
to whom a Stock Option is granted.


V.   ELIGIBILITY AND PARTICIPATION

   
    Grants of ISOs and NSOs may be made to Employees of the Company or any 
Participating Subsidiary.  Grants of NSOs may be made to Employees of, 
directors of or consultants to the Company or any Participating Subsidiary.  
Any director of the Company or of a Participating Subsidiary who is also an 
Employee shall also be eligible to receive ISOs.  The Board or Committee 
shall from time to time determine the Participants to whom Stock Options 
shall be granted, the type of Stock Option granted, the number of shares of 
Common Stock subject to each Stock Option to be granted to each such 
Participant, the Option Price of such Stock Option, and all other terms and 
conditions of the Stock Option, all as provided in the Plan.  The Option 
Price of any ISO shall be not less than the Fair Market Value of a share of 
Common Stock on the date on which the Stock Option is granted, and the Option 
Price of an NSO may not be less than 85% of the Fair Market Value on the date 
the NSO is granted.  If an ISO is granted to an Employee who then owns stock 
possessing more than 10% of the total combined voting power of all classes of 
stock of the Company or any parent or subsidiary corporation of the Company, 
the Option Price of such ISO shall be at least 110% of the Fair Market Value 
of the Common Stock subject to the ISO at the time such ISO is granted, and 
such ISO shall not be exercisable after five years after the date on which it 
was granted.  Each Stock Option shall be evidenced by a written agreement 
("Option Agreement") containing such terms and provisions as the Board or 
Committee may determine, subject to the provisions of the Plan.
    

                                         -3-

<PAGE>

VI.  SHARES OF COMMON STOCK SUBJECT TO THE PLAN


    6.1  MAXIMUM NUMBER.  Subject to adjustment as provided in Section 6.2
below, the maximum aggregate number of shares of Common Stock that may be made
subject to Stock Options shall be 800,000 shares of Common Stock.  Such shares
may either be authorized but unissued or treasury shares of the Company.  The
aggregate Fair Market Value (determined as of the time the ISO is granted) of
the stock as to all ISOs granted to an individual which may first become
exercisable in a particular calendar year may not exceed $100,000.  If any
shares of Common Stock subject to Stock Options are not purchased or otherwise
paid for before such Stock Options expire, such shares may again be made subject
to Stock Options.

    6.2  ADJUSTMENTS.  In the event the outstanding shares of Common Stock of
the Company are increased, decreased, changed into or exchanged for a different
number or kind of securities of the Company, through reorganization,
recapitalization, reclassification, stock dividend, stock split, or other change
in corporate structure, an appropriate and proportionate adjustment shall be
made in the numbers, kinds, and prices of the Stock Options granted under the
Plan (but not in the aggregate purchase price), and in the total number of
shares of Common Stock with respect to which Stock Options may be granted
hereunder.  If any adjustment shall result in a fractional share, the fraction
shall be disregarded, and the Company shall have no obligation to make any cash
or other payment with respect to such a fractional share.  Any adjustment shall
be made by the Board, whose determination in that respect, and as to whether any
adjustment needs to be made, shall be final, binding and conclusive.


VII. EXERCISE OF STOCK OPTIONS


    7.1  TIME OF EXERCISE.  Subject to the provisions of the Plan, the Board or
Committee, in its discretion, shall determine the time when a Stock Option, or a
portion of a Stock Option, shall become exercisable, and the time when a Stock
Option, or a portion of a Stock Option, shall expire.  Such time or times shall
be set forth in the Option Agreement evidencing such Stock Options.  A Stock
Option shall expire, to the extent not exercised, no later than the tenth
anniversary of the date on which it was granted.  The Board or Committee may
accelerate the vesting of any Participant's Stock Option by giving written
notice to the Participant and, with the consent of the holder thereof, modify,
amend or terminate any Stock Option.  Upon receipt of such notice, the
Participant and the Company shall amend the Option Agreement to reflect the new
vesting schedule.  


                                         -4-

<PAGE>

The acceleration of the exercise period of a Stock Option shall not affect the
expiration date of that Stock Option.

    7.2  EXCHANGE OF OUTSTANDING STOCK.  The Board or Committee, in its sole
discretion, may permit a Participant to surrender to the Company shares of the
Common Stock previously acquired by the Participant as part or full payment for
the exercise of a Stock Option.  Such surrendered shares shall be valued at
their Fair Market Value on the date of exercise.

     7.3  PAYMENT.  The exercise price shall be paid in full at the time of
exercise of the Stock Options in cash or in such other form of lawful
consideration as the Board of Directors or the Committee may approve from time
to time, including, without limitation, the transfer of outstanding shares of
Common Stock as provided in Section 7.2.


     7.4  TERMINATION OF EMPLOYMENT BEFORE EXERCISE.  If the employment of a 
Participant who was an Employee of the Company or a Participating Subsidiary 
when the Stock Option was granted shall terminate for any reason other than 
the Participant's death or disability, any Stock Options then held by the 
Participant, to the extent then exercisable under the applicable Option 
Agreement(s), shall remain exercisable after the termination of his 
employment for a period of three months (but not later than the specified 
expiration date). If the Participant's employment is terminated because the 
Participant is disabled within the meaning of Section 22(e)(3) of the Code, 
any Stock Option then held by the Participant, to the extent then exercisable 
under the applicable Option Agreement(s), shall remain exercisable after the 
termination of his employment for a period of twelve months (but not later 
than the specified expiration date).  If the Participant dies while employed 
by the Company or a Participating Subsidiary, or during the three-month or 
twelve-month periods referred to above, his Stock Options may be exercised to 
the extent that they were exercisable on the date of cessation of his 
employment by his estate, or duly appointed representative, or beneficiary 
who acquires the Stock Options by will or by the laws of descent and 
distribution, and each of his Stock Options shall terminate on the first 
anniversary of the date of his death (but not later than the specified 
expiration dates).  To the extent a Stock Option either (i) has not yet 
become exercisable on termination of employment (I.E., not vested) or (ii) is 
exercisable on such termination but is not exercised during the applicable 
period, it shall be deemed to have been forfeited and of no further force or 
effect.  Notwithstanding anything in this Section 7.4 to the contrary, the 
Board or Committee may, in its sole discretion, provide (whether by initial 
grant or subsequent modification or amendment with the consent of the holder 
thereof) other and different provisions with respect to termination, 
expiration and exercisability for NSOs in the event of termination of 
employment, engagement or term, as the case may be, death or disability of 
any Employee, consultant or director (such provisions shall be set forth in 
the Stock Option Agreements evidencing such NSOs).

                                         -5-

<PAGE>

     7.5  DISPOSITION OF FORFEITED STOCK OPTIONS.  Any shares of Common Stock
subject to Stock Options forfeited by a Participant shall not thereafter be
eligible for purchase by the Participant, but may be made subject to Stock
Options granted to other Participants.


VIII.    NO CONTRACT OF EMPLOYMENT


     Nothing in this Plan shall confer upon the Participant the right to
continue in the employ of the Company, or any Participating Subsidiary, nor
shall it interfere in any way with the right of the Company, or any such
Participating Subsidiary, to discharge the Participant at any time for any
reason whatsoever, with or without cause.  Nothing in this Article VIII shall
affect any rights or obligations of the Company or any Participant under any
written contract of employment.


IX.  NO RIGHTS AS A STOCKHOLDER


     A Participant shall have no rights as a stockholder with respect to any
shares of Common Stock subject to a Stock Option.  Except as provided in Section
6.2, no adjustment shall be made in the number of shares of Common Stock issued
to a Participant, or in any other rights of the Participant upon exercise of a
Stock Option by reason of any dividend, distribution or other right granted to
stockholders for which the record date is prior to the date of exercise of the
Participant's Stock Option.


X.   ASSIGNABILITY


     No Stock Option granted under this Plan, nor any other rights acquired by
Participant under this Plan, shall be assignable or transferable by a
Participant, other than by will or the laws of descent and distribution, and
Stock Options issued to a Participant are exercisable during his lifetime only
by him.  Notwithstanding the preceding sentence, the Board or Committee may, in
its sole discretion, permit the assignment or transfer of an NSO and the
exercise thereof by a person other than a Participant, on such terms and
conditions as the Board or Committee in its sole discretion may determine.  Any
such terms shall be determined at the time the NSO is granted, and shall be set
forth in the Option Agreement.  In the event of his death, the Stock Option may
be exercised by the Personal Representative of the Participant's estate or by
the successor or successors in 


                                         -6-

<PAGE>

interest determined under the Participant's will or under the applicable laws of
descent and distribution.


XI.  MERGER OR LIQUIDATION OF THE COMPANY


     11.1 LIQUIDATION.  In the event of a dissolution or liquidation of the
Company, all Stock Options shall terminate immediately prior to the consummation
of such dissolution or liquidation, unless otherwise provided by the Board.  The
Board may, in the exercise of its sole discretion, give each Participant the
right to exercise his or her Stock Option(s) as to Shares as to which the Stock
Option(s) would not otherwise be exercisable.

     11.2 SALE OF ASSETS, MERGER OR CONSOLIDATION.  In the event of a sale of
all or substantially all of the assets of the Company, or the merger or
consolidation of the Company with or into another corporation in a transaction
in which the Company does not survive, the Board, in its sole discretion, may
provide for the acceleration of the exercise date of some or all of the
non-exercisable portion of any outstanding Stock Options, and/or may provide for
the termination of any Stock Options immediately prior to the consummation of
the transaction, and/or may provide for the replacement of any Stock Options
with comparable options to purchase stock of such other corporation.


XII. AMENDMENT


     The Board of Directors may from time to time alter, amend, suspend or
discontinue the Plan, including, where applicable, any modifications or
amendments as it shall deem advisable in order that ISOs will be classified as
incentive stock options under the Code, or in order to conform to any regulation
or to any change in any law or regulation applicable thereto; provided, however,
that no such action shall adversely affect the rights and obligations with
respect to Stock Options at any time outstanding under the Plan; and provided
further that no such action shall, without the approval of the stockholders of
the Company, (i) increase the maximum number of shares of Common Stock that may
be made subject to Stock Options (unless necessary to effect the adjustments
required by Section 6.2), (ii) materially increase the benefits accruing to
Participants under the Plan, or (iii) materially modify the requirements as to
eligibility for participation in the Plan.

XIII.      REGISTRATION OF OPTIONED SHARES


     The Stock Options shall not be exercisable unless the purchase of such
optioned shares is pursuant to an applicable effective registration statement
under the Securities Act of 1933, as amended, or unless, in the opinion of the
Company, the proposed purchase of such optioned shares would be exempt from the
registration requirements of the Securities Act of 1933, as amended, and from
the registration or qualification requirements of applicable state securities
laws.  As a condition to the exercise of a Stock Option, the Company may impose
various conditions, including a requirement that the person exercising such
Stock Option represent and warrant, at the time of such exercise, that the
Shares are being purchased for investment and without any present intention to
sell or distribute the Shares to be received.


XIV. WITHHOLDING TAXES

   
     The Company or Participating Subsidiary shall take such steps as it 
shall deem necessary or appropriate for the withholding of any taxes which 
the Company or the Participating Subsidiary is required by any law or 
regulation of any governmental authority, whether federal, state or local, 
domestic or foreign to withhold in connection with any Stock Options.  All 
withholding taxes may, at the sole discretion of the Board or Committee, be 
satisfied by the withholding of a sufficient number of exercised Shares 
which, valued at Fair Market Value on the date of exercise, would be equal to 
the total withholding obligation of the Optionee for the exercise of such 
Stock Option.
    

XV.  BROKERAGE ARRANGEMENTS


     The Board or Committee, in its discretion, may enter into arrangements with
one or more banks, brokers, or other financial institutions to facilitate the
disposition of shares acquired upon exercise of Stock Options including, without
limitation, arrangements for the simultaneous exercise of Stock Options and the
sale of shares acquired upon exercise.

XVI. NONEXCLUSIVITY OF THE PLAN


     Neither the adoption of the Plan by the Board of Directors nor the
submission of the Plan to stockholders of the Company for approval shall be
construed as creating any limitations on the power or authority of the Board of
Directors to adopt such other or additional incentive or other compensation
arrangements of whatever nature as the Board of Directors may deem necessary or
desirable or preclude or limit the continuation of any other plan, practice or
arrangement for the payment of compensation or fringe benefits to employees,
consultants or directors generally, or to any class or group of employees, which
the Company or any Participating Subsidiary now has lawfully put into effect,
including, without limitation, any retirement, pension, savings and stock
purchase plan, insurance, death and disability benefits and executive short-term
incentive plans.


XVII.    EFFECTIVE DATE


     This Plan was adopted by the Board of Directors and became effective on
March 15, 1994, subject to the approval of the Company's shareholders within
twelve (12) months thereafter.  No Stock Options shall be granted subsequent to
ten years after the effective date of the Plan.  Stock Options outstanding
subsequent to ten years after the effective date of the Plan shall continue to
be governed by the provisions of the Plan.

                                OEM Purchase Agreement

    This Agreement is made this   6th day of    AUG  , 1996, by and between
Image Guided Technologies, Inc., with an address at 5710-B Flatiron Parkway,
Boulder, CO 80301 (hereafter called "IGT") and Radionics Software Applications,
Inc., with an address of 22 Terry Avenue, Burlington, MA USA 01830, (hereafter
called "RSA").

    The parties make the following agreements:

1. The Products to be purchased and/or licensed by RSA from IGT and covered by
this Agreement are listed on Exhibit A.  The per item price for such Products in
US dollars is also listed in Exhibit A, provided however, that prices may change
with ninety (90) days prior written notice by IGT to RSA.  Prices are net of
shipping, insurance and all value-added taxes, customs fees, sales and/or use
taxes; freight by an RSA approved carrier shall be prepaid and added to the
invoice.  RSA shall receive such discounts for quantity purchases as indicated
in Exhibit A.  The discount on any individual purchase order will be based on
the accrued year-to-date quantity and will be taken as earned on each new order.
The discount schedule may change at the yearly anniversary with ninety (90) days
prior written notice by IGT to RSA.  There are no bill-backs for discounts
given.

2. RSA may purchase IGT software licenses for its own use, and subject to the
terms and conditions of this Agreement, IGT hereby grants to RSA, with the right
to sublicense to RSA affiliates, a world-wide, non-exclusive license to use the
IGT software in object code only, for RSA s (or the Affiliate s) own use on the
specified IGT hardware; RSA s own use includes copying portions of the IGT
software in the creation of communication protocols, interfaces or other devices
or programs necessary or desirable to integrate the IGT hardware and IGT
software into the RSA system; RSA shall include all IGT proprietary legends on
such portions copied.  In addition, RSA may rent or lease the IGT software in
object code only to third parties who are renting or leasing RSA systems
incorporating IGT hardware and IGT software.  In addition, RSA may purchase IGT
software licenses and sublicense the IGT software to RSA s or its Affiliates
distributors in the sales channel or to end-users, only in object code form, for
use on specified IGT hardware incorporated in an RSA system.

3. RSA shall submit purchase orders to IGT for Products from time to time; all
purchase orders are governed by the terms and conditions of this Agreement,
except for quantity ordered.  IGT shall accept all such purchase orders, and
shall deliver all Products within the mutually agreed time frame established at
the time the order is received by IGT and IGT agrees to ship at least [ ]
systems per month if required by RSA.  Risk of loss and title to hardware shall
pass at IGT's dock.  Although RSA must indicate an intent to purchase at least
[ ] systems during each year of this agreement to obtain the base OEM discount
of [ ], RSA makes no commitment to purchase any minimum number of Product, nor
does RSA guarantee any profit, revenue or other income to IGT.


                                          1
<PAGE>

4. RSA shall pay IGT for Products shipped within thirty days of receipt of goods
and conforming invoice.  RSA shall pay in US Dollars.

5. RSA may cancel any purchase order with thirty days prior written notice;  RSA
shall take delivery of Product completed during the thirty day wind-down period,
but shall have no other obligation to IGT.

6. IGT warrants the IGT Hardware and Software as set forth in Exhibit B, "The
IGT Product Warranty".  IGT warrants that all Products delivered according to
this Agreement shall, at the time of delivery, conform to the UL and IEC
standards included in the IGT Product specification shown on Exhibit C, Product
Specification, and by June 30, 1997 the Products shall bear the CE mark and
conform to ISO 9000 requirements in effect as of that date.  IGT further
warrants that the software Products shall perform substantially in accordance
with their specifications for a period of one year from date of shipment.  IGT
further warrants that each Product shall be factory tested and qualified, and
that it shall perform in accordance with its written specifications as of the
date of shipment.

    In the event such Product is not returned by IGT within fifteen (15)
business days, or does not perform as warrantied after return except in the case
where such delay is caused by condition(s) beyond IGT s reasonable control,
then, as RSA s exclusive remedy and IGT s sole liability, RSA shall return the
Product and IGT shall issue RSA a refund for the full amount paid.

7. IGT agrees that it shall make no changes to the Product without notifying RSA
in writing ninety (90) days in advance.  IGT may make changes in the design or
manufacture of any Product, provided that the changes do not effect the form,
fit or function of the Product and provided further that IGT shall not make any
changes which may effect any regulatory status or require any additional
regulatory filing, including the FDA, the CE Mark, or other domestic or foreign
registrations.  No additional changes will be made without the prior written
permission of RSA.

8. IGT shall defend in any suit or proceeding brought against RSA to the extent
it is based on a claim that the IGT Product sold or licensed to RSA under this
Agreement directly infringes a patent or copyright; provided IGT is notified
promptly in writing and given authority, information and assistance (at IGT s
expense) for the defense of the suit or proceeding.  IGT shall pay all damages
and costs awarded against RSA in such suit or proceeding or settlement, if and
as long as IGT has been given full control of the defense and the negotiations
for settlement, if any, of the suit or proceeding; IGT agrees to keep RSA fully
informed of the proceedings.  If any IGT Product is held in such suit or
proceeding directly to infringe a patent or copyright or is, in IGT s opinion,
likely to be held directly to infringe a patent or copyright, IGT may, at its
option and expense, either (a) procure for RSA the right to continue using the
IGT Product, (b) replace the IGT Product with non-infringing product, (c) modify
the IGT Product so that it becomes non-infringing , or (d) require the return of
the IGT Product and


                                          2
<PAGE>


refund the purchase price for the IGT Product, such purchase price to be reduced
by 1.67% for each month since the product was first installed by RSA.  IGT shall
have no liability to RSA if the infringement or claim thereof is based upon (a)
the use of the IGT Product in combination with other products, devices or
software which are not furnished to RSA by IGT, (b) modification of the IGT
Product by other than IGT, or (c) use of the IGT Product as part of any
infringing process, apparatus or product; provided however, that IGT will
cooperate with RSA at RSA s request and expense, so long as IGT does not
directly contest the St. Louis University patent (Bucholz).  THIS SECTION STATES
THE ENTIRE LIABILITY OF IGT FOR PATENT OR COPYRIGHT INFRINGEMENT.

9. The term "Confidential Information" means information relating to either
party s business, customers, product, plans or technology, including any trade
secrets, design or technical information, whether written, oral or electronic,
which (i) a party has acquired or developed, and (ii) which a party wishes to
protect and (iii) which is not generally known to competitors;  however, the
term "Confidential Information" does not include any information: (a) which a
party independently develops without use of the other s Confidential
Information, or (b) which is or becomes generally known or part of the public
domain without fault of the receiving party, or (c) which is subsequently freely
disclosed by the originating party without restriction, or (d) which is freely
available from third parties; and further, all Confidential Information must be
identified as such prior to its disclosure and must be in tangible form or
memorialized in tangible form at disclosure.  Neither party shall disclose any
Confidential Information to the other except as provided under a separate,
written agreement, which is to be executed by both parties and which shall
identify the Confidential Information and provide  for the protection of such
information.  In the event one party wishes to disclose Confidential
Information, it shall first notify the other of its intention to make such a
confidential disclosure under a separate written agreement, and indicate, to the
extent able without actually disclosing the Confidential Information, the nature
and extent of the information to be disclosed and the purpose for the
disclosure.  The other party shall state in writing whether or not it wishes to
receive the Confidential Information.  If the parties wish to proceed, they
agree to negotiate a suitable agreement in food faith.  If no agreement on
confidentiality is executed, the Confidential Information shall not be
disclosed.  Neither party shall use the Confidential Information of the other
without the prior written consent of the disclosing party, however, any
information which is disclosed by one party to the other without such written
agreement is not Confidential Information, and can be used freely by the
receiving party.

10. This Agreement shall be governed and construed  in accordance with the laws
of the State of Colorado.

11. This Agreement shall commence on the date stated above and terminate three
years later, unless otherwise extended by the parties.

12. Neither party has any restrictions or obligations, whether express or
implied, which would prevent it from entering into and performing this
Agreement, or would induce a third party to


                                          3
<PAGE>

make any claim of liability.  Both parties are free to conduct their own
businesses, without any restriction not expressly stated in this Agreement.

13. The parties to this agreement are independent contractors, and neither shall
be or be deemed to be the agent, employee, or legal representative of the other.
Nothing in this Agreement shall constitute a partnership or joint venture
between the parties.  No party shall have the right to enter into contracts or
pledge the credit of or incur expenses or liabilities on behalf of the other
party.

14. The waiver or failure of either party to exercise in any respect any right
or remedy under any theory of law or equity shall not be deemed to be a waiver
of any further or future right or remedy.

15. If any provision of this Agreement is found by a Court of competent
jurisdiction to be illegal, invalid or unenforceable in any particular case, the
legality, validity or enforceability of the remaining provisions contained
herein shall not be in any way affected or impaired thereby.

    IN WITNESS WHEREOF, the parties have hereto set their hands and seals on
the dates indicated.  The parties hereto represent to the other that each has
full power and authority to enter into this Agreement and by doing so it is not
in conflict with other agreements or statutes.

                                   PRODUCT WARRANTY

1.  IGT Product Warranty.

    IGT warrants that the IGT Product will be free from defects in
    materials, parts and workmanship for a period of the earlier of one
    (1) year from delivery to the End User or eighteen (18) months to OEM,
    and conforms to IGT's specifications applicable to such IGT Product
    (at the time of OEM's purchase thereof), except that IGT does not
    warrant total system performance if a device or accessory not supplied
    by IGT causes the IGT product to fail or not meet specified
    performance standards, for a period of the earlier of one (1) year
    from delivery to End User or eighteen (18) months to OEM.
    NOTWITHSTANDING THE FOREGOING, IGT MAKES NO WARRANTIES AS TO THE IGT
    ACCESSORIES, SUCH IGT ACCESSORIES BEING SOLD "AS IS."  THIS WARRANTY
    IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
    THOSE OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

2.  Warranty Repair Misuse.

    IGT's sole obligation under the foregoing warranty shall be to repair
    or replace or, where applicable, recalibrate, at IGT's option, at
    IGT's plant, without charge, all defective IGT Products returned for
    inspection within the applicable warranty period and which have been
    mutually determined by IGT and OEM to be defective.  To complete such
    repair, IGT may use, at its sole discretion, new, used or re-
    manufactured parts and IGT will retain and own any such parts replaced.
    All transportation charges for the defective IGT Product shall be paid by
    IGT (provided the method of shipment is pre-approved by IGT).  IGT shall
    not be responsible for any modifications or changes to the IGT Product (and
    OEM shall pay IGT for any services necessitated by any such modifications
    or changes) nor shall IGT be liable for any defects arising out of misuse,
    neglect, failure of electric power, cause other than ordinary use or other
    causes beyond IGT's control.


3.  Limitation of IGT Liability.

    IN NO EVENT SHALL IGT'S LIABILITY UNDER THIS AGREEMENT INCLUDE ANY
    SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR CLAIMS FOR
    LOSS OF BUSINESS OR PROFITS, EVEN IF IGT SHALL HAVE BEEN ADVISED OF
    THE POSSIBILITY OF SUCH POTENTIAL LOSS OR DAMAGE.  NOTWITHSTANDING ANY
    FAILURE OF THE CENTRAL PURPOSE

<PAGE>

    OF ANY LIMITED REMEDY, IGT'S LIABILITY FOR BREACH OF WARRANTY SHALL
    NOT EXCEED THE PURCHASE PRICE FOR SUCH PRODUCT.

4.  No Warranties by IGT to End Users.

    IGT is not making, and this Agreement does not extend, any warranties
    of the IGT Product to End Users, provided that the sale, lease or
    other use of the IGT Products by the End Users shall not limit IGT's
    liability hereunder.  OEM may, in its discretion, extend warranties to
    End Users of OEM's Product.  However, it is understood and agreed that
    IGT is not a party to and does not bear any responsibility or
    liability for such warranties by OEM to End Users, provided that the
    sale, lease or other use of the IGT Products by the End Users shall
    not limit IGT's liability hereinabove.

5.  Service of Warranties to End Users.

    OEM has the sole responsibility and obligation to provide service and
    support on OEM's Product to End Users under warranties or otherwise.
