                                  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 (20.1%) of the estimated net proceeds of
this offering  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.
    
 
                                       6
<PAGE>
The failure by  the Company  to improve its  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.  For the  year ended December 31,  1995 and the six
months ended  June  30,  1996,  sales  to  Zeiss  accounted  for  19%  and  45%,
respectively,  and  sales  to  SNT/Sofamor  Danek  accounted  for  38%  and 30%,
respectively, of the Company's revenues. The Company's contract with Zeiss  will
expire  at  the end  of  October 1996  (though  shipments are  scheduled through
December 1996)  and SNT/Sofamor  Danek  purchases product  from the  Company  by
purchase  order. The  loss of, or  substantial diminution of  purchases from the
Company by, either of  these customers could have  a material adverse effect  on
the  Company. None  of the  Company's 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,  and there  can  be no  guarantee  that these
companies will remain customers of  the Company. 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."
    
 
    PATENTS ON SYSTEMS THAT UTILIZE LOCALIZERS.   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 or uses) in connection
with which a reissue  patent application has been  filed which, if granted,  may
broaden  the claims of that  patent. In addition, the  Company has four original
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 of the Company's  pending or future patent applications  will
be  issued, that  any patent  owned by, or  issued to,  the Company  will not be
invalidated, circumvented or challenged  (including, without limitation, on  the
basis of the SLU Patent or other patents), or that the rights granted thereunder
will  provide meaningful competitive  advantages to the  Company. 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."
    
 
                                       7
<PAGE>
    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  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'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, to  be able to
differentiate their product 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
 
                                       8
<PAGE>
   
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, including  those which  may
arise  from  the  incorporation of  the  Company's Flashpoint  product  into the
customer's product. 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 obtained, owns and  is the sole beneficiary of 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."
 
                                       9

    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 $3.35 per share  of
Common Stock (67%) (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 Underwriter 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.
 
    NASDAQ  ELIGIBILITY AND  MAINTENANCE; POSSIBLE DELISTING  OF SECURITIES FROM
NASDAQ.  In September 1991, the Commission approved new rules that establish new
criteria for initial and continued listing of securities on the Nasdaq  SmallCap
Market.  Under such  rules, for  initial listing, a  company must  have at least
$4,000,000 in total assets, at least  $2,000,000 in stockholders' equity, and  a
minimum  bid price  of $3.00  per share. For  continued listing,  a company must
maintain  at  least  $2,000,000  in   total  assets,  at  least  $1,000,000   in
stockholders' equity, and a minimum bid price of $1.00 per share.
 
    If  at any time after issuance the Common  Stock is not listed on the Nasdaq
SmallCap Market, and  no other exclusion  from the definition  of "penny  stock"
under  the Exchange  Act is  available, transactions  in the  Common Stock would
become subject  to the  penny stock  regulations which  impose additional  sales
practice   requirements  on  broker-dealers  who   sell  securities.  See  "Risk
Factors--Risk of Low-Priced Stocks."
 
    If the Company should experience losses from operations, it may be unable to
maintain the  standards for  continued listing  and the  Common Stock  could  be
subject  to delisting from the  Nasdaq SmallCap Market. Trading,  if any, in the
Common Stock would thereafter be conducted in the over-the-counter market on  an
electronic bulletin board established for securities that do not meet the Nasdaq
SmallCap  Market listing requirements or in what are commonly referred to as the
"pink sheets." As a result,  an investor may find  it more difficult to  dispose
of, or to obtain accurate quotations as to the price of, the Common Stock.
 
    RISK OF LOW-PRICED STOCK.  If the Common Stock were delisted from the Nasdaq
SmallCap  Market, and no other exclusion from  the definition of a "penny stock"
under the Exchange Act were available,
 
                                       10
<PAGE>
such securities would be subject to the penny stock rules that impose additional
sales practice  requirements  on  broker-dealers who  sell  such  securities  to
persons  other than  established customers  and accredited  investors (generally
defined as investors  with net worth  in excess of  $1,000,000 or annual  income
exceeding $200,000 or $300,000 together with a spouse). For transactions covered
by  these rules, the broker-dealer must make a special suitability determination
for the purchase and must have  received the purchaser's written consent to  the
transaction  prior to sale.  Consequently, such delisting, if  it were to occur,
could materially  adversely affect  the ability  of broker-dealers  to sell  the
Common  Stock and the ability of purchasers  in this offering to sell the Shares
in the secondary market.
 
    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. In  addition, any  shares issuable upon
exercise of options  ordinarily could  be sold  publicly, pursuant  to Rule  701
under  the  Securities  Act, commencing  90  days  after the  Company  becomes a
reporting Company under  the Securities Exchange  Act of 1934,  as amended  (the
"Exchange  Act").  However,  shareholders owning  1,612,183  of  the outstanding
1,667,741 shares of Common  Stock and all holders  of outstanding stock  options
and  warrants (other than the Underwriter's Warrants) have agreed 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 Underwriter's  prior written  consent
(which  consent will not be unreasonably withheld); in addition, one shareholder
who owns  6,400 shares  has  agreed to  the above  restrictions  on sale  for  a
12-month  period. The Underwriter  may, in its  sole discretion and  at any time
without notice, release  all or any  portion of the  securities subject to  such
agreements.
    
 
    The  holders  of the  Underwriter'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 Underwriter  should exercise  its  registration
rights  to effect  a distribution of  the Underwriter's Warrants  or the Warrant
Shares, the Underwriter, 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  Underwriter ceases making a  market in the Common  Stock, the Company could
lose the ability to list the Common Stock 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
Underwriter 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  Underwriter's prior  written consent  (which  consent will  not be
unreasonably withheld).  The  Company  will  also sell  to  the  Underwriter  in
connection with this
    
 
                                       11
<PAGE>
   
offering,  for nominal consideration, the  Underwriter's Warrants to purchase an
aggregate of 125,000 shares of Common Stock  at a price per share equal to  115%
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 Underwriter's Warrants
and/  or the  Warrant Shares. The  existence of the  Underwriter'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--Underwriter'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.
 
   
    SUBSTANTIAL  PORTION OF NET PROCEEDS ALLOCATED FOR REPAYMENT OF INDEBTEDNESS
AND GENERAL  CORPORATE  AND  WORKING  CAPITAL  PURPOSES.    Approximately  17.9%
($890,181)  of the estimated net  proceeds from the sale  of the Shares has been
allocated for repayment of indebtedness of the Company, and approximately  33.8%
($1,674,819)  of the estimated net proceeds from the sale of the Shares has been
allocated to general corporate and working capital purposes. Proceeds  allocated
to  general  corporate  and working  capital  purposes  may be  utilized  in the
discretion of the Board of  Directors. As a result,  investors will not know  in
advance  how such  net proceeds  will be  utilized by  the Company.  See "Use of
Proceeds."
    
 
    ELIMINATION  OF  LIABILITY  FOR  DIRECTORS.    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 director's 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 the law,
(iii) for acts specified in Section 7-108-403, CBCA and (iv) for transactions in
which  the director directly or indirectly derived an improper personal benefit.
As a result of  such provisions, the rights  of Company stockholders to  recover
monetary  damages  from  directors  of  the  Company  for  certain  breaches  of
directors' fiduciary duties may be significantly limited. See "Management."
 
    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  1,250,000  Shares
offered  hereby  are  estimated to  be  approximately  $4,965,000 (approximately
$5,808,750 if  the Underwriter's  over-allotment option  is exercised  in  full)
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 $890,181, consisting of
     $775,000 in principal amount of outstanding loans and $115,181 in  interest
     accrued  through October 31, 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   salaries  and  associated  costs  of  additional  marketing  and
     technical support  personnel, trade  show expenses  and product  literature
     costs.
 
   
(3)  Includes  cost  of additional  computers, test  equipment for  research and
     development, and calibration and manufacturing equipment.
    
 
(4)  The balance  of  the  estimated  net proceeds  will  be  used  for  general
     corporate  and working  capital purposes (including  payment of outstanding
     trade 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.

                                DIVIDEND POLICY
 
    The Company has not paid any cash  dividends on its capital stock since  its
inception,  and does not expect to pay cash dividends on its Common Stock in the
foreseeable future. The Company currently intends to reinvest earnings, if  any,
in the development and expansion of its business.

    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.  See "Use of Proceeds." This table  should
be read in conjunction with the Financial Statements and Notes thereto appearing
elsewhere in this Prospectus.

                                    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, 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  $4,824,662  or  $1.65  per  share.  This
represents an immediate increase in net  tangible book value of $1.73 per  share
to  existing shareholders  and an immediate  dilution to new  investors of $3.35
(67%) 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
 
                                       18
<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."
 
                                       19
<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,  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  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.
 
                                       21
<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.  Some customers either do not  use, or purchase their requirements
from  others  for,  reference  devices,  instruments  and  markers.  A  standard
localizer for medical applications containing all of the above parts, other than
the Dynamic Reference Frame, currently has a list price of $25,000.

<PAGE>
    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. For the
year ended December 31, 1995  and the six months ended  June 30, 1996, sales  to
Zeiss  accounted for 19%  and 45%, respectively, and  sales to SNT/Sofamor Danek
accounted for  38%  and  30%,  respectively,  of  the  Company's  revenues.  The
Company's  contract with Zeiss  will expire at  the end of  October 1996 (though
shipments are scheduled through December  1996) and SNT/Sofamor Danek  purchases
product  from  the  Company  by  purchase order.  The  loss  of,  or substantial
diminution of purchases  from the Company  by, either of  these customers  could
have  a material  adverse effect  on the Company.  None of  the customers listed
below 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,  and,
of  course, there can be no guarantee that these companies will remain customers
of the Company.
    
 
    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.  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.
 
                                       23
<PAGE>
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  (whose Pixsys  localizer is integrated  into a  product sold by
Computer Design, Inc.)  uses 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
 
                                       24
<PAGE>
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, BrainLab GmbH and Radionics,  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
 
                                       25
<PAGE>
significant  constraints on  the surgeon, thus  limiting the use  of the device.
Similarly, magnetic field localizers 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 localizer  technology, to  be able  to differentiate
their product 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. An  application to reissue this patent has
been filed  which, if  granted, may  broaden its  claims. The  Company has  four
original  patent applications which are currently pending in 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
 
                                       26
<PAGE>
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  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 market clearance through either a 510(k) notification or a PMA
application. A 510(k) clearance will be
    
 
                                       27
<PAGE>
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  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
 
                                       28
<PAGE>
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 (20.1%) of the estimated
net  proceeds of this  offering 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  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
 
                                       34
<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.
 
   
    At September 15,  1996, options to  acquire 620,397 shares  of Common  Stock
were  outstanding 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, options to acquire 62,800
shares of Common Stock are exercisable at an exercise price equal to the initial
public offering price per  share and options to  acquire 4,000 shares of  Common
Stock  are exercisable at an exercise price  equal to 110% of 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 164,662  additional shares of  its
Common Stock (and a greater amount with the Underwriter'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.

     was determined to be $1.25 per share. The Common Stock price at the end  of
     the   seven-year  option  term  would  be  $1.76  based  on  an  annual  5%
     appreciation rate and $2.44 based on  an annual 10% appreciation rate.  The
     amounts  have been calculated based on  the requirements promulgated by the

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.
 
    Robert E. Silligman, President and  Chief Operating Officer of the  Company,
has  an employment agreement with the Company which expires on December 31, 1998
(the  "Silligman  Agreement").  The  Silligman  Agreement  provides  for  annual
compensation  review provisions similar to those described above with respect to
the Ray Agreement and similar provisions to those set forth in the Ray Agreement
with respect  to  (i)  automatic  option vesting  on  Change  in  Control,  (ii)
severance on
 
                                       36

termination  following  Change in  Control, (iii)  severance on  termination for
other causes  and (iv)  non-compete, non-interference  and non-disturbance  upon
termination of employment. Mr. Silligman's current salary is $115,000.
 
    Waldean  A. Schulz, Vice  President, Technology of the  Company, also has an
employment agreement with the Company (the "Schulz Agreement") which expires  on
December 31, 1998. The Schulz Agreement provides for an annual salary of $80,000
and  provisions similar to  those described above with  respect to the Silligman
Agreement except that the Schulz Agreement, provides for a longer,  twelve-month
non-compete,   non-interference   and   non-disturbance   upon   termination  of
employment.
 
    Jeffrey J.  Hiller,  Vice  President,  Finance  of  the  Company  and  Chief
Financial  Officer,  also  has an  employment  agreement with  the  Company (the
"Hiller Agreement") which  expires on  December 31, 1998.  The Hiller  Agreement
contains  provisions similar  to those  described above  for Mr.  Silligman. Mr.
Hiller's current salary is $100,000.
 
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.

    The  Company believes that the above transactions  were on terms at least as
favorable to the Company as those then available in the marketplace. The Company
intends that  all future  transactions  between the  Company and  its  officers,

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  43
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

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
lockup 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).

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon  completion of this offering, the Company will have 2,917,741 shares of
Common Stock outstanding (3,105,241  shares of Common  Stock outstanding if  the
Underwriter's  over-allotment option is exercised in full). Of these shares, the
1,250,000  Shares  offered  hereby   (1,437,500  shares  if  the   Underwriter's
over-allotment  option is exercised in full) and 9,600 of the shares outstanding
immediately prior  to the  offering  will be  freely tradeable  without  further
registration under the Securities Act. The holders of 1,612,183 of the 1,667,741
shares  of the Common  Stock outstanding immediately prior  to the offering, all
the option  holders under  the  Plan and  the  holder of  currently  outstanding
warrants  to  purchase 40,000  shares of  Common  Stock have  agreed (i)  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 Underwriter's prior  written
consent  (which will  not be unreasonably  withheld); and (ii)  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, one  shareholder  who  owns  6,400 shares  has  agreed  to  the  above
restrictions  on sale for  a 12-month period.  The Underwriter may,  in its sole
discretion and at any  time without notice,  release all or  any portion of  the
securities subject to the above described restrictions on sale.
    
 
   
    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.  Since 9,600 shares of  Common Stock have been
held for at  least three  years and  such shares are  not subject  to the  above
described  restriction on sale, they will be eligible for immediate sale without
restriction in the public  market. The Commission has  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 upon  expiration or release from
such restrictions on sale.
    
 
    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 620,397 shares
of Common Stock issuable upon the exercise of outstanding options under the Plan
(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
 
                                       43
<PAGE>
   
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 Underwriter's Warrants  or
the  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 125,000  additional shares  of Common Stock  may be  purchased by the
Underwriter 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  Underwriter's  Warrants. Any  and all
shares of Common Stock purchased upon the exercise of the Underwriter's Warrants
may be freely tradeable, provided that the Company satisfies certain  securities
registration  and qualification requirements in accordance with the terms of the
Underwriter's Warrants. See "Underwriting."
    
 
    After the offering, the  holders of 574,291 shares  of Common Stock and  the
holder  of the  warrants to  purchase 40,000  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.

                                  UNDERWRITING
 
GENERAL
 
   
    The Underwriter has agreed, subject to the terms and conditions contained in
the  Underwriting Agreement, to  purchase from the Company,  and the Company has
agreed to sell to the Underwriter, the Shares offered hereby.
    
 
    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 Underwriter  are  subject  to
certain  conditions. The Underwriter  shall be obligated to  purchase all of the
shares of Common Stock offered hereby if any are purchased.
 
   
    The Underwriter has advised the Company that it proposes 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 $0.30
per share, of which amount a sum not in excess of $0.10 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  Underwriter. The
Underwriter does not intend to sell any of the Company's securities to  accounts
over which it exercises discretionary authority.
    
 
    The  Company  has  agreed  to  indemnify  the  Underwriter  against  certain
liabilities, including liabilities under the  Securities Act, and to  contribute
to payments the Underwriter may be required to make in respect thereof.
 
   
    The  Company  has agreed  to  pay to  the  Underwriter an  aggregate expense
allowance, on a non-accountable basis, equal to 3% of the gross proceeds derived
from the sale of 1,250,000 shares  of Common Stock offered hereby (or  1,437,500
shares  of Common Stock if the  Underwriter'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 Underwriter'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  Underwriter  may  designate. In  addition,  the  Company will  sell  to the
Underwriter, at an aggregate purchase price of $125, the Underwriter's  Warrants
to  purchase up to an aggregate of 125,000 shares of Common Stock exercisable at
a price per share equal to 115% of the initial public offering price per Share.
    
 
   
    The holders of 1,612,183 of the  1,667,741 shares of Common Stock  currently
outstanding  and all  the option holders  under the  Plan and the  holder of the
warrants (to purchase  40,000 shares  of Common Stock)  have agreed  (i) 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 Underwriter's prior written
consent (which  consent will  not  be unreasonably  withheld)  and (ii)  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;
also, one shareholder who owns 6,400 shares has agreed to the above restrictions
on sale for a 12-month period. In addition, for a period of 18 months after  the
date  of this Prospectus, the Company has agreed that, without the Underwriter's
prior consent (which  consent will 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  Underwriter's Warrants, (ii) options which  may
be  granted under the Plan and up to 164,662 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
 
                                       45
<PAGE>
Company and the Underwriter. 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  Underwriter an option,  exercisable in the
sole discretion  of  the Underwriter  within  45 days  after  the date  of  this
Prospectus,  to purchase up  to an aggregate  of 187,500 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 Underwriter  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 Underwriter.
    
 
UNDERWRITER'S WARRANTS
 
   
    In connection with  this offering,  the Company has  agreed to  sell to  the
Underwriter  for an aggregate purchase price of $125, the Underwriter's Warrants
to purchase up to 125,000 shares of Common Stock. The Underwriter'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  115% of the
initial public offering price per share.  The Underwriter'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 Underwriter and  members of the selling group. The
Underwriter'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 Underwriter's
Warrants have no voting, dividend or other rights as shareholders of the Company
with respect to shares  of Common Stock  underlying the Underwriter's  Warrants,
unless the Underwriter'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  Underwriter'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 Underwriter's  Warrants and/or the
underlying securities from such  requesting holders at a  price, in the case  of
the  Underwriter's Warrants, equal to the  difference between the exercise price
of the Underwriter's Warrants and the current market price (as defined  therein)
of  the Warrant  Shares. In  addition, the  Company has  agreed, for  the period
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  Underwriter's
Warrants  and Warrant Shares of its  intention to file a registration statement,
and in such case, holders of  the Underwriter'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  Underwriter's  Warrants are  exercisable,  the
Underwriter  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
 
                                       46
<PAGE>
since the Underwriter is likely to exercise the Underwriter'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 Underwriter'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 Underwriter 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.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders
 of Image Guided Technologies, Inc.
 
    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:

Customer F...............................................................................                   38%
</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.

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.

                                    PART II
 
                     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 Underwriter  of the Registrant and its  directors
and  officers, and by the Registrant of the Underwriter, 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 Underwriter
at the  closing specified  in the  Underwriting Agreement  certificates in  such
denominations  and registered  in such names  as required by  the Underwriter 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.
