                                STOCK OPTION AGREEMENT
                            Reflects 12/9/94 Stock Split*


THIS STOCK OPTION AGREEMENT is issued to ((FULLNAME)) (the "Optionee"), pursuant
to the 1994 Stock Option Plan (the "Plan") of Image Guided Technologies, Inc., a
Colorado corporation (the "Corporation").

1.    OPTIONEE; BASIC TERMS. The Optionee is hereby granted an option to
      purchase the number of fully paid and non-assessable shares of the Common
      Stock, no par value, of the Corporation at the option price set forth
      below, subject to the following additional terms and conditions:

      (a)    DEFINITIONS.

             (i)    "Code" shall mean the Internal Revenue Code of 1986, as
                    amended from time to time.

             (ii)   "Incentive Stock Option" shall mean an option described in
                    Section 422 of the Code.  To qualify for favorable tax
                    treatment provided by an Incentive Stock Option, the shares
                    purchased upon exercise must be held for a period of two
                    (2) years from the date of the option grant and for a
                    period of one (1) year after the shares are transferred to
                    Optionee.

             (iii)  "Non-Statutory Option" shall mean an option other than an
                    Incentive Stock Option, the exercise of which generally
                    results in an immediate taxable event.

             (iv)   Unless otherwise indicated, all capitalized terms set forth
                    in this Agreement shall have the meaning provided to them
                    under the Plan, a copy of which Optionee acknowledges
                    having received.

      (b)    GRANT OF OPTION.

             (i)    The Corporation hereby grants to the Optionee an option
                    (the "Option") to purchase ((SHARES)) shares of the Common
                    Stock of the Corporation, upon the terms and conditions set
                    forth below.  The date of grant of the Option is
                    ((GRANTDATE)) (the "Grant Date").

             (ii)   This Option is a(n):

                    /  / Incentive Stock Option (to be received only by
                         EMPLOYEES of the Corporation).

                    /  / Non-Statutory Option.


- --------------------

*The number of shares granted and the price per share as set forth in this Stock
Option Agreement both reflect the four-for-one stock split on 12/9/94, and thus
no further adjustment for such stock split is required.



             (iii)  The Optionee is a(n) (if applicable, check more than one):

                    /  / Employee
                    /  / Consultant
                    /  / Director

      (c)    DURATION OF OPTION.  This Option shall expire five (5) years from
             the Grant Date; provided, however, for any Optionee who owns more
             than ten percent (10%) of the total combined voting power or value
             of all classes of stock of the Corporation, the duration of an
             Incentive Stock Option shall be five (5) years.

      (d)    EXERCISE PRICE.  The purchase price for the shares subject to the
             Option shall be $((PRICE)) per share.

2.    EXERCISABILITY.  Subject to the provisions relating to termination, death
      or permanent disability as set forth in the Plan and paragraph 6 herein,
      this Option shall vest over a three-year period, in equal quarterly
      installments, beginning after six months from Grant Date, I.E., one-sixth
      of the option shares shall be exercisable six months after the Grant
      Date, and one twelfth of the option shares shall be exercisable at the
      end of each quarter thereafter.  Under these provisions, the Option is
      fully exercisable 36 months after the Grant Date.  The holder of the
      Option shall not have any of the rights of a shareholder with respect to
      the Shares covered by the Option except to the extent that one or more
      certificates for such Shares shall be delivered to him or her upon the
      due exercise of the Option.

3.    METHOD OF EXERCISING OPTION.

      (a)    Subject to the terms and conditions of this Option Agreement, the
             Option may be exercised by written notice to the Corporation, at
             its principal office, in substantially the form of Exhibit A
             attached hereto. Such notice shall be accompanied by payment of
             the full purchase price of such shares, and the Corporation shall
             deliver a certificate or certificates representing such shares as
             soon as practicable after the notice is received.

      (b)    Optionee agrees to have withheld from any remuneration payable to
             him or her by the Corporation and/or to pay to the Corporation, at
             the time of exercise of the Option, an amount which is required to
             be withheld or paid pursuant to any Federal, State or local tax or
             revenue laws or regulations, as may be determined by the
             Corporation.

      (c)    The certificate or certificates for the shares as to which the
             Option shall have been exercised shall be registered in the name
             of the person or persons exercising the Option.  In the event the
             Option shall be exercised pursuant to the Plan by any person or
             persons other than the Optionee, such notice shall be accompanied
             by appropriate proof of the right of such person or persons to
             exercise the Option. All shares that shall be purchased upon the
             exercise of the Option as provided herein shall be fully paid and
             nonassessable.


                                         -2-



4.    NONTRANSFERABILITY. The Option shall not be transferable otherwise than
      by will or the laws of descent and distribution, and the Option may be
      exercised, during the lifetime of the Optionee, only by the Optionee or
      his or her legal representative.  The Option shall be null and void and
      without effect upon any attempted assignment or transfer, except as
      hereinabove provided, including without limitation, any purported
      assignment, whether voluntary or by operation of law, pledge,
      hypothecation or other disposition contrary to the provisions hereof.

5.    DISCLOSURE AND RISK.  The Optionee represents and warrants to the
      Corporation as follows:

      (a)    This Option and the Shares will be acquired by the Optionee for
             Optionee's own account, for investment and not with a view to, or
             for resale in connection with, any distribution or public offering
             thereof within the meaning of the Securities Act of 1933, as
             amended (the "Securities Act").

      (b)    The Optionee understands that: (i) at time of grant and exercise,
             the Option and the Shares have not been and probably will not have
             been registered under the Securities Act by reason of their
             issuance in a transaction exempt from the registration and
             prospectus delivery requirements of the Securities Act, and that
             they must be held by the Optionee indefinitely; (ii) that the
             Optionee must therefore bear the economic risk of such investment
             indefinitely, unless a subsequent disposition thereof is
             registered under the Securities Act or is exempt from
             registration; (iii) that Rule 144, the usual exemption from
             registration, is only available after the satisfaction of certain
             holding periods and in the presence of a public market for the
             Shares, that there is no certainty that a public market for the
             Shares will exist, and that otherwise it will be necessary that
             the Shares be sold pursuant to another exemption from registration
             which may be difficult to satisfy.

      (c)    That because of Optionee's position with or relationship to the
             Corporation and as a result of inquiries made by Optionee and
             information furnished to Optionee by the Corporation, Optionee has
             as of the Grant Date and will have as of the date of exercise,
             reviewed all information necessary to make an informed investment
             decision.

      (d)    That Optionee understands that each certificate representing the
             Shares shall be endorsed with the following legend: 

             "THE SHARES REPRESENTED BY THE CERTIFICATE HAVE NOT BEEN
             REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT"), AND ARE
             "RESTRICTED SECURITIES" AS THAT TERM IS DEFINED IN RULE 144 UNDER
             THE ACT.  THE SHARES MAY NOT BE OFFERED FOR SALE, SOLD OR
             OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
             STATEMENT UNDER THE ACT, OR PURSUANT TO AN EXEMPTION FROM
             REGISTRATION UNDER THE ACT, THE AVAILABILITY OF WHICH IS TO BE
             ESTABLISHED TO THE SATISFACTION OF THE COMPANY."


                                         -3-



      The Corporation need not register a transfer of any of the Shares unless
      one of the conditions specified in the foregoing legend is satisfied.

6.    TERMINATION, DEATH, DISABILITY.  In the event of the termination, death
      or disability of the Employee, the Option granted to the Employee
      hereunder shall expire as provided in Section 7.4 of the Plan.  If the
      Optionee is a consultant or director, to the extent any Option (or
      portion thereof) has not yet become exercisable (I.E., not vested) on the
      Optionee's ceasing to be engaged as a consultant by or ceasing to be a
      director of the Corporation, the Option (or portion thereof) not then
      exercisable on the occurrence of such event shall be deemed to have been
      forfeited and of no further force or effect.

7.    NOTIFICATION UPON TRANSFER OF ISO SHARES.  If this Option is an Incentive
      Stock Option, the Optionee understands that, under certain conditions,
      disposition of the Shares subject to this Option Agreement could result
      in adverse tax consequences because of failure to meet prescribed holding
      period requirements.  Moreover, if this Option is an Incentive Stock
      Option, the Optionee hereby agrees to notify the Corporation in writing
      within three (3) days after any sale, transfer or other disposition of
      shares acquired upon the exercise of this Option which occurs within
      either twelve (12) months following the date of exercise or twenty-four
      (24) months following the Grant Date.

IN WITNESS WHEREOF, the Corporation has caused this Option Agreement to be duly
executed by its officers thereunto duly authorized, and the Optionee has
executed this Agreement, all as of the Grant Date set forth in paragraph 1(b)
(i) above.
