                    12% SUBORDINATION PROMISSORY NOTE

$500,000                                                    December 12, 1997


     On December 12, 1998 (the "Maturity Date"), and as hereinafter provided, 
for value received, IMAGE GUIDED TECHNOLOGIES, INC., a Colorado corporation 
("Company"), promises to pay to CRUTTENDEN ROTH, INC., a California 
corporation ("Lender"), or order, the principal sum of $500,000, together 
with interest from the date hereof on the unpaid principal balance of this 
Note at the rate of twelve percent (12%) per annum.  Interest shall be 
computed at the above rate on the basis of the actual number of days elapsed, 
divided by 360, which shall, for interest computation purposes, be considered 
one year.  Interest shall be payable in arrears on the first day of each 
calendar month and on the Maturity Date.  All of the obligations evidenced by 
this Note shall, if not sooner paid, in any event become and be due and 
payable in full to the Lender by the Company on the Maturity Date.  All 
payments by the Company to the Lender hereunder shall be made without set-off 
or counterclaim, and in immediately available funds, at the location 
specified from time to time by the Lender.

     The Company irrevocably authorizes the Lender to make appropriate 
notations on any SCHEDULE attached to this Note to evidence the outstanding 
principal amount of this Note and repayments thereof.  Any such notations 
indicating the outstanding principal amount of this Note shall be rebuttable 
presumptive evidence of the principal amount of this Note outstanding, but 
the failure to make any such notation or any error in making any such 
notations, shall not limit or affect the obligations of the Company hereunder.

     In the event of any Event of Default, the Lender may, by written notice 
to the Company, declare the entire outstanding principal of this Note, and 
all accrued and unpaid interest thereon, to be immediately due and payable, 
whereupon all such principal and interest shall, without further notice, 
become and be immediately due and payable. The term "Event of Default," as 
used herein, shall mean any of the following events: (i) any failure by the 
Company to make any payment of principal or interest hereunder when the same 
shall be due and payable, and the continuation of such failure for two 
business days, (ii) the failure of the Company to comply with any other 
covenant set forth herein, which failure shall continue for five business 
days, (iii) the Company shall become insolvent or make an assignment for the 
benefit of creditors, (iv) the Company shall apply for or consent to or shall 
permit or suffer to exist the voluntary or involuntary appointment of a 
trustee, receiver, custodian, or liquidator of all or any material part of 
its property, or (v) the Company shall have commenced against it, or shall 
voluntarily commence, any bankruptcy, reorganization or other similar 
proceeding under bankruptcy or insolvency laws or any dissolution, winding up 
or liquidation proceeding, which, in the case of any such involuntary 
proceeding, shall have been consented to by the Company, shall have resulted 
in entry of an order for relief against the Company, or shall have remained 
undismissed, undischarged or unbonded for a period of more than 60 days.

     The Company waives diligence, presentment, demand, notice, protest and 
all other notices in connection with the delivery, acceptance, performance or 
enforcement of this Note, and assents to all extensions of time for payment, 
forbearances and other indulgences without notice. In any action brought 
under or arising out of this Note, the Company, including its successor(s) or 
assign(s), hereby consents to the application of Massachusetts law.

AMENDED, RESTATED OR OTHERWISE MODIFIED FROM TIME TO TIME, THE "LOAN 
AGREEMENT"), BETWEEN THE COMPANY AND IMPERIAL BANK ("SENIOR LENDER"). ALL OF 
THE INDEBTEDNESS AND OTHER OBLIGATIONS AND LIABILITIES OF THE COMPANY 
EVIDENCED BY THIS NOTE ("SUBORDINATED DEBT") SHALL BE SUBORDINATED AND JUNIOR 
IN RIGHT OF PAYMENT TO THE INDEBTEDNESS AND OTHER OBLIGATIONS AND 
LIABILITIES OF THE COMPANY UNDER THE LOAN AGREEMENT ("SENIOR DEBT") ON THE 
TERMS SET FORTH IN THE SUBORDINATION AGREEMENT, DATED AS OF DECEMBER 12, 
1997, BETWEEN THE LENDER AND THE COMPANY (AS AMENDED, RESTATED OR OTHERWISE 
MODIFIED FROM TIME TO TIME, THE "SUBORDINATION AGREEMENT").

   The Company hereby agrees with the Lender that on or prior to January 15, 
1998, the Company will execute, for the benefit of the Lender, one or more 
security agreements granting to the Lender a security interest in all of the 
Company's assets on terms reasonably satisfactory to the Lender, and such 
financing statements and other instruments as the Lender may reasonably 
request in order to perfect such security interest.

   Simultaneously with the implementation of the security arrangements 
described above, the Company and the Lender will amend and restate the 
Subordination Agreement to provide, upon customary terms, as follows:

       (a)  No payments or distributions will be permitted on Subordinated 
   Debt while any payment default is continuing on Senior Debt.

       (b)  While any bankruptcy or insolvency proceeding with respect to the 
   Company is continuing, no payments or distributions will be permitted on 
   Subordinated Debt until all Senior Debt has been paid in full in cash.
   
       (c)  No payments or distributions in respect of Subordinated Debt will 
   be permitted while any Payment Blockage Period is continuing. Payment 
   Blockage Periods may be commenced by the Senior Lender by delivering a 
   notice to the Lender while any event(s) of default are continuing under the 
   Loan Agreement, specifying such event(s) of default. Payment Blockage Periods
   shall expire on the earlier of (i) the date on which the specified event(s) 
   of default have been cured, or (ii) the 180th day after commencement of the 
   Payment Blockage Period.

       (d)  No remedies may be exercised by the Lender in respect of 
   Subordinated Debt or any collateral therefor while any Remedy Standstill 
   Period is continuing. Remedy Standstill Periods may be commenced by the 
   Senior Lender by delivering a notice to the Lender while any event(s) of 
   default are continuing under the Loan Agreement, specifying such event(s) of 
   default. Remedy Standstill Periods shall expire on the earlier of (i) the 
   date the specified event(s) of default are cured, or (ii) the 180th day after
   commencement of the Remedy Standstill Period.

       (e)  All liens securing Subordinated Debt shall be subordinated and 
   junior to liens securing Senior Debt.

       (f)  There shall be a permanent standstill on the exercise of remedies 
   by the Lender in respect of any collateral for Subordinated Debt until all 
   Senior Debt has been paid in full in cash.
