                                   LOAN AGREEMENT

                           DATED AS OF: DECEMBER 12, 1997

THIS LOAN AGREEMENT, dated as of December 12, 1997, is entered into between 
IMAGE GUIDED TECHNOLOGIES, INC., a Colorado corporation (herein called 
"Borrower"), and IMPERIAL BANK, a California bank (herein called "Bank").

     1.   REVOLVING LOANS.

     a.   COMMITMENT TO MAKE REVOLVING LOANS.  Bank hereby commits, subject 
to all the terms and conditions of this Agreement, and prior to the 
termination of the Commitment as hereinafter provided, to make loans to 
Borrower from time to time ("Revolving Loans") in such amounts up to, but not 
exceeding in the aggregate unpaid principal balance at any time, the 
Commitment Amount at such time.  The Bank's Commitment shall terminate on the 
Commitment Termination Date, and Bank shall have no obligation hereunder to 
make any Revolving Loans to Borrower after that date.  The Commitment may 
terminate prior to the Commitment Termination Date in accordance with Section 
11 or 12 hereof.

     b.   REQUESTS FOR REVOLVING LOANS.  Each request for a Revolving Loan 
hereunder shall be in writing duly executed by Borrower in a form 
satisfactory to Bank and shall contain a certification (i) setting forth, in 
reasonable detail, calculations establishing to the reasonable satisfaction 
of Bank that Borrower is entitled to the amount of the Revolving Loan being 
requested, (ii) that on the date of such Revolving Loan, and before and after 
giving effect to such Revolving Loan, all representations and warranties of 
the Principal Companies set forth herein and in the other Loan Documents will 
be true and correct, and (iii) that no Default or Event of Default shall be 
continuing on the date of such Revolving Loan, either before or after giving 
effect to such Revolving Loan or the application by Borrower of the proceeds 
thereof.  Anything herein to the contrary notwithstanding, Bank shall not be 
obligated to make any Revolving Loan to Borrower while any Default or Event 
of Default shall be continuing, or if any Default or Event of Default would 
arise from the making of such Revolving Loan or the application of the 
proceeds thereof.  The proceeds of Revolving Loans shall be used by Borrower 
for general corporate purposes not prohibited by this Agreement.

     c.   LOAN ACCOUNT; REPAYMENTS AND PREPAYMENTS OF REVOLVING LOANS.  The 
amount of each Revolving Loan made by Bank to Borrower hereunder shall be 
debited to the loan ledger account of Borrower maintained by Bank (herein 
called "Loan Account"), and Bank shall credit the Loan Account with all 
repayments of Revolving Loans made by Borrower.  Borrower promises to pay 
Bank the unpaid balance of the Loan Account on June 30, 1999 or such earlier 
date on which the outstanding principal of the Revolving Loans shall be 
declared to be or shall otherwise become due and payable pursuant to Section 
11 or 12 hereof (June 30, 1999 or such earlier date being called the 
"Revolving Loan Maturity Date"). Revolving Loans may be prepaid by Borrower 
at any time without premium or penalty.

     In the event that the unpaid balance of the Loan Account shall at any 
time exceed the maximum amount of outstanding Revolving Loans to which 
Borrower is entitled under SECTION 1.a, Borrower promises immediately to pay 
to Bank, for credit to the Loan Account, the amount of such excess.

     d.   REVOLVING NOTE.  The obligations of Borrower in respect of the 
Revolving Loans and any interest accrued thereon shall also be evidenced by a 
Promissory Note executed and delivered by Borrower to Bank on the date 
hereof, in the face amount of $2,000,000 ("Revolving Note").  Borrower hereby 
irrevocably authorizes Bank to make appropriate notations on any Schedule 
attached to such Revolving Note, which notations, if made, shall evidence the 
date of, the outstanding principal of and payments on the Revolving Loans 
evidenced thereby.  Bank's notations on any Schedule attached to the 
Revolving Note shall constitute rebuttable presumptive evidence of the 
principal amount of Revolving Loans outstanding, but the failure to record 
such information on any such Schedule shall not limit or affect the 
obligations of Borrower hereunder or under the Revolving Note to make 
payments of principal or interest on the Revolving Loans when due.

     e.   FINAL DETERMINATION OF ADVANCE RATE AND MAXIMUM COMMITMENT.  
Borrower acknowledges that, as of the date of this Agreement, Bank is 
conducting an audit of the Collateral of the Principal 

                              Page 1


Companies, including the Accounts of the Principal Companies ("Collateral 
Audit").  Upon completion of the Collateral Audit, Bank will prepare and 
deliver to Borrower the Collateral Audit Report, specifying the Advance Rate 
and the Maximum Commitment.  From and after delivery by Bank to Borrower of 
the Collateral Audit Report, the Advance Rate and the Maximum Commitment 
specified in the Collateral Audit Report shall be applicable for all purposes 
of this Agreement, PROVIDED, HOWEVER, that any increase (above $1,250,000) in 
the Maximum Commitment reflected in the Collateral Audit Report shall only be 
effective from and after the closing date of the Qualified Financing.  Until 
the closing date of the Qualified Financing, the Maximum Commitment 
originally specified herein ($1,250,000) shall continue to be applicable for 
all purposes of this Agreement.  Borrower acknowledges that the Advance Rate 
specified by Bank in the Collateral Audit Report may be less than .75.

     2.   TERM LOAN.

     a.   COMMITMENT TO MAKE TERM LOAN.  Bank hereby commits to make a loan 
to Borrower on the date hereof ("Term Loan") in the amount of $4,000,000.  
The proceeds of the Term Loan shall be used by Borrower to finance the 
acquisition of Brimfield pursuant to the Agreement of Purchase and Sale, 
dated as of November 25, 1997, among Borrower, Brimfield and the stock 
holders of Brimfield ("Brimfield Purchase Agreement").

     b.   REPAYMENT OF TERM LOAN.  Borrower promises to pay to Bank the 
aggregate principal of the Term Loan in thirty-six equal monthly installments 
on the last day of each calendar month commencing with the first such 
installment payment on January 31, 1998.  The aggregate outstanding principal 
amount of the Term Loan shall, if not sooner paid, be in any event due and 
payable in full on December 12, 2000 ("Term Loan Maturity Date").  The 
outstanding principal amount of the Term Loan may be prepaid by Borrower 
without penalty or premium at any time.  Any such optional prepayments shall 
reduce each of the remaining installment payments of principal on the Term 
Loan in the inverse order of the respective due dates of such installments.

The obligations of Borrower in respect of the Term Loan and any interest 
accrued thereon shall be evidenced by a Promissory Note executed and 
delivered to Bank on the date hereof, in the face amount of $4,000,000 ("Term 
Note").  Borrower hereby irrevocably authorizes Bank to make appropriate 
notations on any Schedule attached to the Term Note, which notations, if 
made, shall evidence the date of, the outstanding principal of, and payments 
on the Term Loan evidenced thereby. Bank's notations on any Schedule attached 
to the Term Note shall constitute rebuttable presumptive evidence of the 
principal amount of the Term Loan outstanding, but any failure to record any 
information on any such Schedule shall not limit or affect the obligations of 
Borrower hereunder or under the Term Note to make payments of principal or 
interest on the Term Loan when due.

     3.   INTEREST.  Borrower promises to pay to Bank interest (i) on the 
average daily unpaid balance of the Loan Account, at the rate of three 
quarters of one percent (.75%) per annum in excess of the rate of interest 
announced by Bank from time to time as its prime lending rate (as the same 
may vary from time to time, "Prime Rate") and (ii) on the aggregate 
outstanding principal amount of the Term Loan at the rate of one and one-half 
percent (1.5%) per annum in excess of the Prime Rate.  Interest shall be 
computed at the above rates on the basis of the actual number of days elapsed 
divided by 360, which shall for interest computation purposes be considered 
one year.  Interest accrued on the outstanding principal of the Loan Account, 
and on the outstanding principal of the Term Loan, shall be payable in 
arrears on the first day of each calendar month.  All accrued and unpaid 
interest on the balance of the Loan Account shall in any event be due and 
payable on the Revolving Loan Maturity Date.  All accrued and unpaid interest 
on principal of the Term Loan shall in any event be due and payable on the 
Term Loan Maturity Date.

     4.   DEFAULT INTEREST, ETC.  Upon the occurrence and during the 
continuance of any Event of Default, the entire principal balance of the Loan 
Account and the entire outstanding principal of the Term Loan (whether or not 
such balance or such principal shall then be due and payable hereunder) shall 
bear interest at the rate of five percent (5%) per annum in excess of the 
rate otherwise applicable to the principal balance of the Loan Account, or 
the outstanding principal of the Term Loan, as applicable.  To the extent 
permitted by applicable law, all overdue interest, fees, charges and other 
sums (other than principal) payable under this Agreement and the other Loan 
Documents shall bear interest at the rate of five percent (5%) per annum in 
excess of the rate otherwise applicable to principal of the Term Loan.  All 
interest that shall accrue under this SECTION 4 shall be due and payable upon 
demand by Bank and, in any event, on the first day of each calendar month.

     5.   PAYMENTS.  All payments required to be made by Borrower to Bank
hereunder or under any of the Loan Documents shall be made at the SANTA CLARA
REGIONAL OFFICE OF BANK AT 226 AIRPORT PARKWAY, SAN JOSE, CALIFORNIA, on or

charges, sums or other amounts (other than principal or interest) due and 
payable under the Loan Documents, SECOND, to accrued and unpaid interest, and 
THIRD, to the unpaid balance of the Loan Account or the Term Loan, in such 
order as Bank shall determine.

     6.   SECURITY.  All of the obligations of Borrower to Bank under this 
Agreement, the Revolving Note, and the other Loan Documents shall be secured

under this Agreement, Borrower represents and warrants to Bank that (each of 
which representations will be deemed repeated as of the date of any Revolving 
Loan hereunder as if made on such date):

     a.   ORGANIZATION; POWER AND AUTHORITY.  Each Principal Company is duly 
organized and existing as a corporation in the jurisdiction of its 
organization; each of the Loan Documents to which any Principal Company is a 
party has been duly and validly executed and delivered by such Principal 
Company; and the execution, delivery and performance by each Principal 
Company of each Loan Document to which such Principal Company is a party are 
within such Principal Company's corporate powers, have been duly authorized 
by such Principal Company, and are not in conflict with any applicable law or 
with any Ancillary Documents, any of the charter documents of any charter or 
by-laws, or any indenture, material agreement or undertaking to which any 
Principal Company is a party or by which any Principal Company is bound or 
affected.  The obligations of each Principal Company set forth in the Loan 
Documents (including the Guaranty Agreement) to which such Principal Company 
is a party constitute legal, valid and binding obligations of such Principal 
Company, enforceable against such Principal Company in accordance with their 
respective terms, SUBJECT, HOWEVER, to any applicable bankruptcy or 
insolvency laws affecting generally the enforcement of creditors' rights 
against such Principal Company, and to the discretion of any court with 
respect to the enforcement of any equitable remedies.

     The Warrant has been duly and validly executed and delivered by 
Borrower; the execution, delivery and performance of the Warrant are within 
Borrower's corporate powers, have been duly authorized and are not in 
conflict with any applicable law or with the terms of Borrower's charter or 
by-laws, as amended, or any indenture, agreement or undertaking to which 
Borrower is a party or by which Borrower is bound or affected.  The 
obligations of Borrower set forth in the Warrant constitute legal, valid and 
binding obligations of Borrower, enforceable against Borrower in accordance 
with their respective terms, SUBJECT, HOWEVER, to any applicable bankruptcy 
or insolvency laws affecting generally the enforcement of creditors rights 
against Borrower, and to the discretion of any court with respect to the 
enforcement of any equitable remedies.

     b.   LITIGATION.  There is no litigation or other proceeding pending or 
threatened against or affecting any Principal Company that could reasonably 
be expected to have a Materially Adverse Effect, and no Principal Company is 
in default with respect to any order, writ, injunction, decree or demand of 
any court or other governmental or regulatory authority.

     c.   FINANCIAL CONDITION.

     i.   The unaudited consolidated balance sheet of Borrower and its
subsidiaries as of September 30, 1997, and the related unaudited consolidated
income statement and cash flows of Borrower and its subsidiaries (collectively,
"Financials"), copies of which have heretofore been delivered to Bank by
Borrower, and all other statements and data submitted in writing by Borrower to
Bank in connection with this request for credit, and not subsequently
supplemented, modified or amended in writing to Bank, are true and correct, and
the Financials fairly present the consolidated financial condition of Borrower
and its subsidiaries as of the dates thereof and the consolidated results of 

                                       Page 6



the operations of Borrower and its subsidiaries for the periods covered 
thereby, and have been prepared in accordance with generally accepted 
accounting principles on a basis consistently maintained.  Since September 
30, 1997, there have been no events or occurrences which, individually or in 
the aggregate, have had or are reasonably likely to have a Materially Adverse 
Effect.  Borrower has no knowledge of any liabilities, contingent or 
otherwise, at September 30, 1997 not reflected in the balance sheet as of 
such date which are required under such generally accepted accounting 
principles to be so reflected, and Borrower has not entered into any special 
commitments or substantial contracts since the date of such balance sheet, 
other than the Brimfield Purchase Agreement and other contracts entered into 
in the ordinary and normal course of its business which could not reasonably 
be expected to have a Materially Adverse Effect.  Except for Borrower's and 
the Guarantors' obligations under the Loan Documents, and the Indebtedness 
for Borrowed Money reflected in SCHEDULE 10(b)(v) attached hereto, none of 
the Principal Companies has any Indebtedness for Borrowed Money.

     ii.  The projected consolidated financial statements of Borrower and its

1998, and December 31, 1999, in each case prepared on a PRO FORMA basis 
giving effect to the transactions contemplated by the Brimfield Purchase 
Agreement ("Projections"), copies of which have heretofore been delivered by 
Borrower to Bank, have been prepared on the basis of the assumptions 
accompanying them and reflect the best good faith estimates by Borrower of 
the performance of Borrower and its subsidiaries for the periods covered 
thereby, and the financial condition of Borrower and its subsidiaries as of 
the dates thereof, based on such assumptions.

     d.   TRADEMARKS, PATENTS, COPYRIGHTS.  Each Principal Company, as of the 
date hereof, possesses all necessary trademarks, service marks, trade names, 
copyrights, patents, patent rights, and licenses known to be required to 
conduct its business as now operated, without any known conflict with any 
trademarks, trade names, copyrights, patents or license rights of others.

patent or patent application held or filed by any Principal Company, (ii) 
registered trademark or service mark, or trademark or service mark 
registration application, held or filed by any Principal Company, and (iii)

Company or whether such Principal Company has applied for any such 
registration.

     e.   TAX STATUS.  No Principal Company has any liability for any 
delinquent state, local or federal taxes.

     f.   SUBSIDIARIES; CAPITALIZATION:  SCHEDULE 9(F) sets forth a true and 
complete list of all direct and indirect subsidiaries of Borrower, together 
with its state of organization or incorporation.  SCHEDULE 9(f) also sets 
forth with respect to each Guarantor, the authorized capital stock of such

capital stock of any Guarantor, and there are no outstanding securities 
convertible into or exchangeable for any capital stock of any Guarantor.

     g.   AFFILIATE TRANSACTIONS.  Except as described in SCHEDULE 9(g) 
attached hereto, no Principal Company is a party to or otherwise bound by any 
written or oral contracts with any Associated Person.  Except as described on 
SCHEDULE 9(g), there is no Indebtedness for Borrowed Money owing by any 
Principal Company to any Associated Person, and there is no Indebtedness for

where such contract is oral, a true and complete description thereof) 
described in SCHEDULE 9(g).

     h.   OTHER REPRESENTATIONS.  Each of the representations and warranties 
of any Principal Company in any of the other Loan Documents is true and 
correct. To the best knowledge of the Borrower, each of the representations 
and warranties of Brimfield or any stockholder of Brimfield set forth in the 
Brimfield Purchase Agreement was true and correct in all material respects as 
of the date made, and is true and correct on the date hereof.

     i.   BRIMFIELD PURCHASE AGREEMENT.  Simultaneously with the closing of 
the transactions contemplated by this Agreement, the Borrower will acquire

effect on the original date thereof) have been satisfied, without any 
amendment or waiver of any such conditions not approved in writing by Bank.  
The sources and uses of funds statement delivered by Borrower to Bank on 
December 11, 1997 represents a true and accurate description of the sources 
and uses of funds of Borrower in connection with the transactions 
contemplated by the Brimfield Purchase Agreement.

default by any Principal Company in the payment when due of any obligation of 
such Principal Company under this Agreement or any of the other Loan 
Documents; (ii) default by Borrower of any agreement, promise or covenant of 
Borrower under SECTION 10(a)(i), 10(a)(ii), 10(a)(iii), 10(a)(iv), 10(a)(vi) 
or 10(b); (iii) default by any Principal Company in the due performance or 
observance of any of the agreements, promises or covenants of such Principal 
Company under any of the Loan Documents or any Warrant, other than, with 
respect to Borrower, any such agreements, promises or covenants described in 
clause (i) or (ii) above, which default shall continue unremedied for ten or 
more days after notice from Bank to Borrower; (iv) any material 
representation or warranty of any Principal Company set forth in any of the 
Loan Documents or any Warrant, or in any certificate, instrument or statement 
delivered to Bank pursuant to any Loan Document or any Warrant, shall be 
untrue or incorrect in any material respect when made; (v) default by any 
Principal Company or any other party of any of its material obligations or 
agreements under any Ancillary Document, which default continues unremedied 
for ten or more days after notice from Bank to Borrower; (vi) any Principal 
Company shall default in the payment when due (whether at stated maturity, by 
acceleration or otherwise) of $100,000 or more of any Indebtedness for 
Borrowed Money, or any Principal Company shall default in the observance or 
performance of any term, covenant or agreement contained in any instrument 
governing or evidencing any Indebtedness for Borrowed Money, and such default 
shall permit the holders of such Indebtedness for Borrowed Money to declare 
immediately due and payable or to otherwise 

                                       Page 12



accelerate Indebtedness for Borrowed Money in an aggregate amount exceeding 
$100,000; (vii) any Change of Control shall occur; (viii) Borrower shall have 
failed to complete a Qualified Financing on terms reasonably satisfactory to 
Bank on or prior to March 15, 1998; (ix) any Principal Company shall become 
insolvent or make an assignment for the benefit of creditors; (x) any 
Principal 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; (xi) 
any Principal 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 such Principal Company, shall have resulted in entry of 
an order for relief against such Principal Company, or shall have remained 
undismissed, undischarged or unbonded for a period of more than 60 days; or 
(xii) any other event or circumstance shall occur or arise which, in the 
reasonable judgment of Bank, has had or is reasonably likely to have a 
Materially Adverse Effect; then, in any such event, Bank may, at its option 
and without demand first made and without notice to any Principal Company, do 
any one or more of the following: (a) terminate the Commitment; (b) declare 
all obligations of the Principal Companies to Bank under this Agreement, the 
Guaranty Agreement and the other Loan Documents immediately due and payable; 
and (c) proceed to enforce all or any of its rights under any of the Loan 
Documents or available at law or in equity.  In the event Bank sells or 
disposes of any Collateral, and a sufficient sum is not realized from any 
such sale or disposition to pay all obligations of the Principal Companies to 
Bank under this Agreement, the Guaranty Agreement, any of the other Loan 
Documents or otherwise, each of the Principal Companies shall be liable to 
Bank for any deficiency.

     In addition, in the event of the occurrence of any Event of Default 
under CLAUSE (viii) above, Borrower will issue to Bank (x) on and as of March 
15, 1997, a Warrant entitling the Bank to purchase 80,000 shares of 
Borrower's Common Stock (as proportionately adjusted for any stock splits, 
split-ups, stock dividends or other recapitalizations or other similar 
transactions effecting Borrower's Common Stock), at a purchase price per 
share calculated in the same manner as the initial Warrant hereunder (but as 
of March 15, 1998), and (y) on the last day of each calendar month thereafter 
(commencing March 31, 1998) on which such Event of Default is continuing, a 
Warrant entitling Bank to purchase 10,000 shares of Borrower's Common Stock 
(as proportionately adjusted for any stock splits, split-ups, stock dividends 
or other recapitalizations or other similar transactions affecting Borrower's 
Common Stock), at a purchase price per share calculated in the same manner as 
the initial Warrant hereunder (but as of the date of issuance of such 
additional Warrants).  Each of the additional Warrants will be in 
substantially the form of the initial Warrant issued hereunder.

     12.  ATTACHMENT, ETC.  If any  garnishment, execution or other legal 
process  be issued against any property of any Principal Company, or if any 
assessment for taxes against any Principal Company is made by any Federal or 
State government or any department thereof relating to an amount unpaid or in 
dispute in excess of $100,000, the Commitment shall immediately terminate and 
all obligations hereunder or under any of the Loan Documents shall 
immediately become due and payable without demand, presentment or notice of 
any kind.

     13.  SETOFF.  Regardless of the adequacy of any Collateral, during the 
continuance of any Default or Event of Default, any deposits or other sums 
credited by or due from Bank to any Principal Company, and any securities or 
other investments or property of such Principal Company in the possession of 
Bank, may be applied to or set off against any obligations of such Principal 
Company to Bank under this Agreement or any other Loan Document.
                                          
     14.  FEES.  Borrower shall pay to Bank (a) a non-refundable closing fee 
for the transactions contemplated by the Loan Documents in an amount equal to 
$50,000, payable in four equal quarterly payments with the first payment due 
on the date hereof and the remaining three payments due on March 1, 1998, 
June 1, 1998 and September 1, 1998 (and, in any event, with any unpaid 
balance thereof due on the Revolving Loan Maturity Date), and (b) commitment 
fees at the annual rate of one half of one percent (0.5%) on the average 
daily amount by which the Maximum Commitment exceeds the outstanding balance 
of the Loan Account.  The commitment fees shall be payable in arrears on the 
first day of each calendar month and on the Revolving Loan Maturity Date.
                                          
     15.  SPECIAL POST-CLOSING COVENANT.  On or prior to January 15, 1999, 
Borrower will deliver to Bank, in a form satisfactory to Bank, a registration 
rights agreement entitling Bank, on customary terms, to (i) one demand 
registration of the shares of Common Stock issuable upon exercise of the 
Warrants on Form S-3 or other similar "short-form", and (ii) unlimited 
"piggyback" registration rights with respect to such shares of Common Stock, 
subject to standard pro rata underwriter's cut-backs.

     16.  FAILURE OR INDULGENCE NOT WAIVER.  No failure or delay on the part 
of Bank in the exercise of any power, right or privilege hereunder, under the 
Guaranty Agreement or under any other Loan Document, shall operate as a 
waiver thereof, nor shall any single or partial exercise thereof or of any 
other right, power or privilege preclude 

                                       Page 13



other or further exercise thereof or of any other right, power or privilege.  
All rights and remedies existing hereunder are cumulative to, not exclusive 
of, any other rights or remedies provided in any of the Loan Documents or at 
law or in equity.

     17.  CHOICE OF LAW; WAIVER OF JURY TRIAL.  THIS AGREEMENT AND EACH OF 
THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE 
WITH, THE LAWS OF THE STATE OF CALIFORNIA.  BORROWER AGREES THAT ANY SUIT FOR 
THE ENFORCEMENT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS MAY BE 
BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR ANY FEDERAL COURT SITTING 
THEREIN AND CONSENTS TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS AND TO 
SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON BORROWER IN ANY MANNER 
PERMITTED BY CALIFORNIA LAW.  EACH PARTY WAIVES ITS RIGHT TO A JURY TRIAL 
WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION 
WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR 
OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR 
OBLIGATIONS.

     18.  AMENDMENT AND WAIVER.  This Agreement is subject to modification 
only by a writing signed by Bank and Borrower.  Bank shall not be deemed to 
have waived any right hereunder unless such waiver shall be in writing and 
signed by Bank.  A waiver on any one occasion shall not be construed as a bar 
to or waiver of any right on any future occasion.

     19.  DATE OF AGREEMENT.  This Agreement is executed by and on behalf of 
the parties as of December 12, 1997.
