                   LARSON DAVIS INCORPORATED AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accompanying financial statements have been prepared by the Company
without audit.  In the opinion of management, all adjustments (which include
only normal recurring adjustments) necessary to present fairly the financial
position, results of operations, and changes in financial position at September
30, 1996, and for all periods presented have been made.

     Certain information and footnote disclosure normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted.  It is suggested that these condensed
consolidated financial statements be read in conjunction with the Company's June
30, 1996, audited financial statements and the notes thereto.  The results of
the operations for the period ended September 30, 1996, may not necessarily be
indicative of the operating results for the year ending June 30, 1997.

     Business Presentation.  The accompanying condensed consolidated financial
statements of LarsonoDavis Incorporated include the accounts of the Company and
its wholly-owned subsidiaries, LarsonoDavis Laboratories Corporation, Sensar
Corporation, and LarsonoDavis Ltd. (a UK Corporation).  All significant
intercompany transactions and accounts have been eliminated in consolidation.

     Reclassifications.  Certain reclassifications have been made to the 1995
finical statements to conform with the 1996 presentation and are not material.

     Cash and Cash Equivalents.  For purpose of the financial statements, the
Company considers all highly liquid debt instruments purchased with a maturity
of three months or less to be cash equivalents.

     Inventories.  Inventories are valued at the lower of cost (using the
average cost method) or market.

     Plant and Equipment.  Equipment is carried at cost less related accumulated
depreciation.  Depreciation, including amortization of capitalized leases, is
computed using the straight-line method over useful lives ranging from 5 to 10
years.  Buildings and improvements are being depreciated over a useful life of
30 years using the straight-line method.

     Intangible Assets.  The Company capitalizes all costs incurred to develop
software after technological feasibility has been established.  Costs incurred
to acquire product technology and license rights are capitalized.  These costs
are being amortized over estimated useful lives ranging from 5 to 17 years by
the straight-line method.

     Preferred Stock Dividend.  During the period ended September 30, 1996, the
Company recognized preferred stock dividends payable on 200,000 shares of issued
and outstanding preferred stock in the amount of $11,250 and $15,000 for the
same period in 1995.

     Translation of Foreign Currencies.  The foreign subsidiary's asset and
liability accounts originally recorded in local currency are translated into U.
S. dollar amounts.  Transaction gains/losses and intercompany foreign currency
transactions are not material and are included in general and administrative
expenses.  Foreign currency translation adjustments are accumulated as a
separate component of stockholders' equity.

     Revenue Recognition.  The Company recognizes revenues on the majority of
its product sales and services at the time of product delivery or the rendering
of services.  With respect to recognizing long-term contract revenues and
charging expenses to operations, the Company has adopted the percentage-of-
completion method of recognizing revenues and accruing expenses.  Revenues are
accrued and a current, non-trade receivable is created based on estimates of the
completed portion of the contract.  Losses on long-term contracts are recognized
when they become apparent.

     Research and Development Costs.  Research and development costs have been
charged to expense as incurred.

     Earnings (Loss) Per Share.  The computation of earnings (loss) per share of
common stock is based on the weighted average number of shares and common stock
equivalents outstanding during the period.  The weighted average number of
shares outstanding for the periods ended September 30, 1996 and 1995, is
10,350,000 and 7,576,427, respectively.

NOTE H - RELATED PARTY TRANSACTION

     During the three-month period ended September 30, 1996, the Company
purchased 49,272 shares of common stock from two directors, at a value of
approximately $325,000.  The stock was then reissued to a third party as payment
of royalty and related obligations of Sensar Corporation.



                 ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS
                             OR PLAN OF OPERATIONS

BUSINESS DEVELOPMENT

     The Company previously announced its intention to implement a development
plan which, in general, included acquiring compatible technologies, raising
sufficient capital funding, undertaking product development, and entering into
marketing relationships with recognized industry leaders.  The initial steps of
this plan have been successfully implemented.  The Company acquired its
CrossCheck technology in 1994 and Sensar Corporation in 1995.  In the 15 month
period ended September 30, 1996, the Company received capital infusions from the
exercise of options and warrants in the net amount of approximately $10,000,000.
The Company anticipates the introduction of four new significant Sensar products
during the first calendar quarter of 1997.  Other product development efforts
based on the CrossCheck technology are continuing.  The Company has also entered
into two marketing agreements with SAES/Getters and Weidmann, both leaders in
their respective industries.  Currently, the Company is involved in ongoing
discussions with other potential strategic alliance partners in an effort to
expand its market penetration capabilities.  The Company is hopeful that these
efforts will lead to new markets and increased revenues from its non-acoustic
and vibration business by the end of fiscal year 1997, although the potential
impact of such matters cannot currently be quantified.

     Expenditures related to the business development plan discussed above are
reflected throughout the financial statements and are not isolated to a single
account classification.  For example, the Company is building its management and
control infrastructure which affects its selling, general, and administrative
costs.  This accounts for part of the approximately $357,000 increase which
occurred between the three-month periods ending September 30, 1996 and 1995,
which were $922,483 and $565,161, respectively.

     One direct comparison is research and development expenses for the two
periods.  For the three months ended September 30, 1996 and 1995, research and
development costs were $736,795 and $402,370, respectively.  This approximately
$334,000 increase is an indication of the emphasis currently being placed on
product development by the Company.

BALANCE SHEET ANALYSIS

     Current Assets

     Total current assets decreased by 9% during the three-month period ended
September 30, 1996.  The significant portion of the change was a decrease in
cash and cash equivalents of approximately $1,250,000.  The funds were in part
used to reduce current liabilities of the Company and to fund development
efforts.

     Current Liabilities

     Total current liabilities decreased by 32% during the three-month period
ended September 30, 1996.  A decrease of approximately $558,000 in notes payable
is a result of reducing the Company's line of credit balance.  Also, accrued
liabilities decreased by approximately $308,000 as a result in part of payments
related to commissions and royalties payable.


     Other Balance Sheet Accounts

     Other balance sheet accounts experienced expected business cycle
fluctuations which are in line with revenue and general business activities for
the period.

STATEMENT OF OPERATIONS ANALYSIS

     The statement of operations for the period ended September 30, 1996, is not
representative of the expected operations for the year ended June 30, 1997.  The
Company anticipates fulfilling two large orders during the second fiscal quarter
with a combined invoice value of approximately $900,000, a portion of which was
manufactured (but not shipped or recognized) along with the products that were
shipped during the September 30, 1996, quarter.  This is in part reflected in
the increase in the work in process inventory for the three-month period ended
September 30, 1996.  It is anticipated shipment of those orders will result in
an increase in revenues during the second fiscal quarter.

     As a percentage of net sales, selling, general, and administrative expenses
for the three-month period ended September 30, 1996, is 43% as compared to 30%
for the same period ended September 30, 1995.  As part of its planned
development, the Company has begun to increase marketing support and technical
sales efforts.  This is in preparation for the anticipated increase in revenues
generated from the introduction of new products.  Also, annual costs for the
preparation of the Company's year end reports, including audit and legal fees
associated with preparing its Form 10-KSB, are normally recognized during this
fiscal quarter.  Professional fees in 1996 were higher than those in 1995.  This
is due, in part, to the Company's appointment of a new auditing firm, which
justifiably included necessary additional time and costs associated with
establishing a new audit relationship.  It is anticipated the percentage
comparison of selling, general, and administrative expenses with net sales will
remain at approximately the one percentage level or perhaps decrease slightly in
upcoming quarters.

     Net sales

     Net sales for the three-month periods ended September 30, 1996 and 1995,
were $2,158,714 and $1,892,248, respectively.  This represents an approximately
14% increase.  In comparison with the fourth quarter of fiscal 1996, the
increase is approximately 21% (net sales for the quarter ended June 30, 1996,
were $1,785,904).  An increase of approximately $420,000 in the work in process
inventory (balances at June 30, and September 30, 1996, of $680,972 and
$1,100,962, respectively) indicates in part the financial effect of a product
build-up for future delivery.

     Costs and Operating Expenses

     A comparison of the percentage of cost of sales to net sales for the three-
month period ended September 30, 1996, and the fiscal year ended June 30, 1996,
is 44% and 50%, respectively.  The costs associated with Sensar products have
been drastically reduced as a result of improved purchasing procedures and a
redesign of critical electronic components.  For the three-month periods ended
September 30, 1996 and 1995, the comparison is 44% and 36%, respectively.
Management anticipates, in time, the Company's cost of sales will stabilized in
the 40% to 43% range.

     The Company is engaged in a highly technical field and has traditionally
made a significant commitment to research and development.  Until the
implementation of the planned development effort previously discussed, research
and development costs averaged about 11% of net sales.  For the three-month
periods ended September 30, 1996 and 1995, these costs were 34% and 21%,
respectively.

     Other Income (Expenses)

     The 75% decrease in other expenses is due to an increase in interest income
earned by investing cash reserves and the reduction of short-term debt.  The
Company invests its excess cash in an agreement with a bank to purchase through
a daily repurchase plan securities of the United States government.  At
September 30, 1996 and 1995, cash and cash equivalents were $2,673,135 and
$172,251, respectively.  Interest income for the three months ended September
30, 1996 and 1995, were approximately $29,000 and $0, respectively.  With its
improved cash position, the Company has reduced borrowing and, consequently, its
interest expense.  For the three months ended September 30, 1996 and 1995,
interest expenses were approximately $58,000 and $101,000, respectively.

CAPITAL AND LIQUIDITY

     The Company received proceeds from the issuance of common stock on the
exercise of warrants and options in the net amount of approximately $9,270,000
during the fiscal year ended June 30, 1996.  During the three-month period ended
September 30, 1996, an additional approximately $760,000 was received.  Capital
obtained from these fund raising activities has in part been used to supplement
the Company's operations allowing for the funding of accelerated research and
development.

     At September 30, 1996, the Company's working capital ratio was 4.4:1
($8,835,855 in current assets compared to $2,017,496 in current liabilities).  A
part of the Company's available capital resources is a line of credit with a
commercial lending institution which has a limit of $3,000,000 and is adjusted
from time to time based on inventory and accounts receivable ratios.  The
outstanding balance of the line of credit on September 30, 1996, was
approximately $775,000.  The Company considers its current liquidity position to
be favorable and anticipates sufficient cash available from operations,
borrowing capabilities, and reasonably anticipated capital funding to meet its
anticipated capital expenditures during the remainder of the current fiscal
year.

                    Amount and Terms of the Credit Facility

     Section 2.1  Advances.  On the terms and subject to conditions of this
Section, the Lender agrees, on the terms and subject to the conditions herein
set forth, to make Advances to each Borrower from time to time during the period
from the date hereof to and including the Termination Date, or the earlier date
of termination in whole of the Credit Facility pursuant to Sections 2.4(c) or
8.2 hereof, in an aggregate amount at any time outstanding not to exceed such
Borrower's Borrowing Base, which Advances shall be secured by the Collateral as
provided in Article III hereof.  The Credit Facility made available to each
Borrower pursuant to this Section 2.1(a) shall be a revolving facility and it is
contemplated that the Borrowers will request Advances, make prepayments and
request additional Advances.  The Borrowers agree to comply with the following
procedures in requesting Advances under this Section 2.1:

          (a)  No Borrower will request any Advance under this Section 2.1 if,
     after giving effect to such requested Advance, (i) the outstanding and
     unpaid Advances made to such Borrower under this Section 2.1 would exceed
     such Borrower's Borrowing Base, or (ii) the aggregate Advances made to both
     Borrowers under this Section 2.1 would exceed the Commitment.

          (b)  Each request for an Advance under this Section 2.1 shall be made
     to the Lender prior to 11:00 a.m. (Colorado time) of the day of the
     requested Advance.  Each request for an Advance may be made in writing or
     by telephone, specifying the date of the requested Advance and the amount
     thereof, and shall be by (i) any officer of the Borrower requesting the
     Advance; or (ii) any person designated as such Borrower's agent by any
     officer of such Borrower in a writing delivered to the Lender; or (iii) any
     person reasonably believed by the Lender to be an officer of such Borrower
     or such a designated agent.

               (1)  Upon fulfillment of the applicable conditions set forth in
          Article IV hereof, the Lender shall promptly disburse loan proceeds by
          crediting the same to such Borrower's demand deposit account
          maintained with Key Bank of Utah, unless the Lender and such Borrower
          shall agree in writing to another manner of disbursement.  Upon
          request of the Lender, such Borrower shall promptly confirm each
          telephonic request for an Advance by executing and delivering an
          appropriate confirmation certificate to the Lender.  Such Borrower
          shall be obligated to repay all Advances under this Section 2.1
          notwithstanding the failure of the Lender to receive such confirmation
          and notwithstanding the fact that the person requesting the same was
          not in fact authorized to do so.  Any request for an Advance under
          this Section 2.1, whether written or telephonic, shall be deemed to be
          a joint and several representation by the Borrowers that (i) the
          condition set forth in Section 2.1(a) hereof has been met, and (ii)
          the conditions set forth in Section 4.2 hereof have been met as of the
          time of the request.

     Section 2.2  Notes.  All Advances made by the Lender under Section 2.1
hereof shall be evidenced by and be repayable with interest in accordance with,
in the case of Advances requested by LDL, the LDL Note, and, in the case of
Advances requested by Sensar, the Sensar Note.  The principal of the LDL Note
and the Sensar Note shall be payable as provided herein and on the earlier of
the Termination Date or acceleration by the Lender pursuant to Section 8.2
hereof, and shall bear interest as provided herein.

     Section 2.3  Interest.
     
          (a)  The principal of the Advances outstanding from time to time
     during any month shall bear interest (computed on the basis of actual days
     elapsed in a 360-day year) as follows:

               (1)  Advances pursuant to Section 2.1 hereof and evidenced by the
          LDL Note or the Sensar Note shall bear interest at an annual rate
          equal to the sum of the Base Rate plus 2.5%, which rate shall change
          when and as the Base Rate changes.

               (2)  Notwithstanding anything contained in this Section 2.3 or
          the Notes to the contrary (i) from the first day of any month during
          which any Default or Event of Default occurs or exists at any time, in
          the Lender's discretion and without waiving any of its other rights
          and remedies, the rate of interest payable on any and all Advances and
          on the Notes shall be the rate otherwise payable with respect to such
          Advances and the Notes plus 3.0%, and (ii) in no event shall any rate
          change be put into effect which would result in a rate greater than
          the highest rate permitted by law.

               (3)  Notwithstanding the interest payable pursuant to Section
          2.3(a)(1) and (2) hereof, if the sum of the interest payable on the
          LDL Note and the Sensar Note for any month is not equal to at least
          $8,000, the Borrowers shall jointly and severally pay the Lender on
          the last day of such month, the difference between $8,000 and the
          amount of the interest payable under the LDL Note and the Sensar Note,
          but not more than the maximum amount of interest permitted by
          applicable law.  The minimum interest charge for periods of less than
          one month shall be suitably pro rated.

          (b)  Interest accruing on the principal balance of the Advances
     outstanding from time to time shall be payable on the last day of each
     month and on the Termination Date or earlier maturity or prepayment in
     full.

          (c)  If any Person shall acquire a participation in Advances under
     this Agreement, the Borrower shall be obligated to the Lender to pay the
     full amount of all interest calculated under Section 2.3(a) hereof, along
     with all other fees, charges and other amounts due under this Agreement,
     regardless if such Person elects to accept interest with respect to its
     participation at a lower rate, or otherwise elects to accept less than its
     pro rata share of such fees, charges and other amounts due under this
     Agreement.

     Section 2.4  Voluntary Prepayment; Termination of Agreement by Borrower.

          (a)  Either Borrower may, in its discretion, prepay its Note in whole
     or from time to time in part without penalty or premium.

          (b)  The Borrowers may terminate this Agreement at any time and,
     subject to payment and performance of all the Borrowers' obligations to the
     Lender, may obtain any release or termination of the Security Interests to
     which the Borrower is otherwise entitled by law by (i) giving at least 30
     days' prior written notice to the Lender of the Borrowers' intention to
     terminate this Agreement; and (ii) paying the Lender a termination fee
     equal to 2.0% of the Commitment if such termination occurs prior to October
     1, 1997, and 1.5% of the Commitment if such termination occurs after
     September 30, 1997, if the Borrowers terminate this Agreement effective as
     of any date other than the Termination Date or under circumstances whereby
     the Credit Facility is refinanced by a lender other than an affiliate of
     Norwest Corporation or if either Borrower enters into a credit facility
     with or borrows money from any source other than an affiliate of Norwest
     Corporation within 90 days from the date of such termination.
     Notwithstanding the foregoing no termination fee shall be payable if this
     Agreement is terminated within 60 days of the date on which the Lender
     requests reimbursement from the Borrower pursuant to Section 2.11.
     
     Section 2.5  Mandatory Prepayment.  Without notice or demand, if the sum of
the outstanding principal balance of the Advances made to a Borrower pursuant to
Section 2.1 shall at any time exceed the Borrowing Base of such Borrower, such
Borrower shall immediately prepay the Advances made to it to the extent
necessary to reduce the sum of the outstanding principal balance of the Advances
made to it pursuant to Section 2.1 to the Borrowing Base of such Borrower.  Any
payment received by the Lender under this Section 2.5 or under Section 2.4 may
be applied to the Advances to such Borrower, including interest thereon and any
fees, commissions, costs and expenses hereunder and under the other Loan
Documents, in such order and in such amounts as the Lender, in its discretion,
may from time to time determine.

     Section 2.6  Payment.  All payments of principal of and interest on the
Advances shall be made to the Lender in immediately available funds.  Each
Borrower hereby authorizes the Lender, in its discretion at any time or from
time to time and without request by the Borrower, to make an Advance to such
Borrower in the amount of any interest due and payable by such Borrower
hereunder or the amount of any fees, costs or expenses due and payable hereunder
or under any other Loan Documents by such Borrower.

     Section 2.7  Payment on Non-Banking Days.  Whenever any payment to be made
hereunder shall be stated to be due on a day which is not a Banking Day, such
payment may be made on the next succeeding Banking Day, and such extension of
time shall in such case be included in the computation of interest on the
Advances or the fees hereunder, as the case may be.

     Section 2.8  Liability Records.  The Lender may maintain from time to time,
at its discretion, liability records as to any and all advances made or repaid
and interest accrued or paid under this Agreement.  All entries made on any such
record shall be presumed correct until the Borrowers establish the contrary.  On
demand by the Lender, the Borrowers will admit and certify in writing the exact
principal balance that the Borrowers then assert to be outstanding to the Lender
under this Agreement.  In the absence of manifest error, any billing statement
or accounting rendered by the Lender shall be conclusive and fully binding on
the Borrowers unless specific written notice of exception is given to the Lender
by the Borrowers within 30 days after its receipt by the Borrowers.

     Section 2.9  Setoff.  The Borrowers agree that the Lender may at any time
or from time to time, at its sole discretion and without demand and without
notice to anyone, setoff any liability owed to the Borrowers by the Lender,
whether or not due, against any indebtedness owed to the Lender by the Borrowers
(for Advances or for any other transaction or event), then due and payable.  In
addition, each other Person holding a participating interest in the Note shall
have the right to appropriate or setoff any deposit or other liability then owed
by such Person to the Borrowers, whether or not due, and apply the same to the
payment of said participating interest, as fully as if such Person had lent
directly to the Borrowers the amount of such participating interest.

     Section 2.10  Fees.  (a) The Borrowers hereby jointly and severally agree
to pay the Lender a fully earned and non-refundable origination fee of $30,00O,
due and payable upon the execution of this Agreement.

          (b)  The Borrowers jointly and severally agree to pay the Lender a
     commitment fee at the rate of one-half of one percent (0.50%) per annum on
     the daily unused amount of the Commitment (determined by taking into
     account the aggregate outstanding Advances to both Borrowers) from the date
     hereof to and including the date on which the Credit Facility is
     terminated, due and payable in arrears commencing October 1, 1996, and
     continuing on the first day of each month thereafter, provided that any
     commitment fee remaining unpaid upon termination of the Credit Facility or
     acceleration of the Notes by the Lender pursuant to Section 8.2 hereof
     shall be due and payable on the date of such termination or acceleration.
     Such fee shall be calculated on the basis of the actual number of days
     elapsed in a 360-day year.
     
          (c)  The Borrowers hereby jointly and severally agree to pay the
     Lender, on demand, audit fees of $50.00 per auditor (or if different, the
     Lender's then current hourly auditor charge) in connection with any audits
     or inspections by the Lender of any collateral or the operations or
     business of either Borrower, together with all reasonable out-of-pocket
     costs and expenses incurred in conducting any such audit or inspection.

     Section 2.11  Capital Adequacy.  If the Lender shall determine that the
adoption after the date hereof of any applicable law, rule or regulation
regarding capital adequacy, or any change therein after the date hereof, any
change after the date hereof in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender or its
parent corporation with any guideline or request issued after the date hereof
regarding capital adequacy (whether nor not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on the Lender's or the Lender's parent corporation's
capital as a consequence of the Lender's obligations hereunder to a level below
that which the Lender or its parent corporation could have achieved but for such
adoption, change or compliance (taking into consideration the Lender's policies
with respect to capital adequacy and those of the Lender's parent corporation)
by an amount deemed to the Lender or its parent corporation to be material, then
from time to time on demand by the Lender, the Borrowers shall jointly and
severally pay to the Lender such additional amount or amounts as will compensate
the Lender or its parent corporation for such reduction.  Certificates of the
Lender sent to the Borrowers from time to time claiming compensation under this
Section, stating the reason therefor and setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to the Lender
hereunder shall be conclusive absent manifest error.  In determining such
amounts, the Lender or its parent corporation may use any reasonable averaging
and attribution methods.  Notwithstanding the foregoing, no amounts shall be
payable pursuant to this Section 2.11 if the Borrower terminates this Agreement
and pays all of the outstanding obligations within 60 days from the date of a
demand by the Lender for reimbursement hereunder.

                                  ARTICLE III
                               Security Interest

     Section 3.1  Grant of Security Interest.  Each Borrower hereby assigns and
grants to the Lender a security interest (collectively referred to as the
"Security Interests") in the Collateral, as security for the payment and
performance of each and every debt, liability and obligation of every type and
description which such Borrower may now or at any time hereafter owe to the
Lender (whether such debt liability or obligation now exists or is hereafter
created or incurred, whether it arises in a transaction involving the Lender
alone or in a transaction involving other creditors of such Borrower, and
whether it is direct or indirect, due or to become due, absolute or contingent,
primary or secondary, liquidated or unliquidated, or sole, joint, several or
joint and several, and including specifically, but not limited to, all
indebtedness of such Borrower arising under this Agreement or any other loan or
credit agreement or guaranty between such Borrower and the Lender, whether now
in effect or hereafter entered into; all such debts, liabilities and obligations
are herein collectively referred to as the "Obligations" of such Borrower).

     Section 3.2  Notification of Account Debtors and Other Obligors.  In
addition to the rights of the Lender under Section 6.10 hereof, with respect to
any and all rights to payment constituting Collateral the Lender may, at any
time before the occurrence of an Event of Default, notify any account debtor or
other person obligated to pay the amount due that payment shall be made directly
to a Lockbox, and may at any time after the occurrence of an Event of Default
which is continuing, notify such Person that the right to such payment has been
assigned to the Lender for security and shall be paid directly to the Lender.
The Borrowers will join in giving such notice if the Lender so requests.  At any
time after the occurrence of an Event of Default which is continuing, the Lender
may, but need not, in the Lender's name or in such Borrower's name, (a) demand,
sue for, collect or receive any money or property at any time payable or
receivable on account of, or securing, any such right to payment, or grant any
extension to, make any compromise or settlement with or otherwise agree to
waive, modify, amend or change the obligations (including collateral
obligations) of any such account debtor or other obligor; and (b) as agent and
attorney in fact of such Borrower, notify the United States Postal Service to
change the address for delivery of such Borrower's mail to any address
designated by the Lender, otherwise intercept such Borrower's mail, and receive,
open and dispose of such Borrower's mail, applying all Collateral as permitted
under this Agreement and holding all other mail for such Borrower's account or
forwarding such mail to such Borrower's last known address.

     Section 3.3  Assignment of Insurance.  As additional security for the
payment and performance of the Obligations, each Borrower hereby assigns to the
Lender any and all monies (including, without limitation, proceeds of insurance
and refunds of unearned premiums) due or to become due under, and all other
rights of such Borrower with respect to, any and all policies of insurance now
or at any time hereafter covering the Collateral or any evidence thereof or any
business records or valuable papers pertaining thereto, and such Borrower hereby
directs the issuer of any such policy to pay all such monies directly to the
Lender.  At any time, whether before or after the occurrence of any Event of
Default, the Lender may (but need not), in the Lender's name or in such
Borrower's name execute and deliver proof of claim, receive all such monies,
endorse checks and other instruments representing payment of such monies, and
adjust, litigate, compromise or release any claim against the issuer of any such
policy.

     Section 3.4  Occupancy.  (a) Each Borrower hereby irrevocably grants to the
Lender the right to take possession of the Premises of such Borrower at any time
after the occurrence and during the continuance of an Event of Default.

          (b)  The Lender may use the Premises only to hold, process,
     manufacture, sell, use, store, liquidate, realize upon or otherwise dispose
     of goods that are Collateral and for other purposes that the Lender may in
     good faith deem to be related or incidental purposes.

          (c)  The right of the Lender to hold the Premises shall cease and
     terminate upon the earlier of (i) payment in full and discharge of all
     Obligations, and (ii) final sale or disposition of all goods constituting
     Collateral and delivery of all such goods to purchasers.

          (d)  The Lender shall not be obligated to pay or account for any rent
     or other compensation for the possession, occupancy or use of any of the
     Premises; provided, however, in the event that the Lender does pay or
     account for any rent or other compensation for the possession, occupancy or
     use of any of the Premises, the Borrowers shall jointly and severally
     reimburse the Lender promptly for the full amount thereof.  In addition,
     the Borrowers will jointly and severally pay, or reimburse the Lender for,
     all taxes, fees, duties, imposts, charges and expenses at any time incurred
     by or imposed upon the Lender by reason of the execution, delivery,
     existence, recordation, performance or enforcement of this Agreement or the
     provisions of this Section 3.4.

     Section 3.5  License.  Each Borrower hereby grants to the Lender a non-
exclusive, worldwide and royalty-free license, to the full extent of such
Borrower s rights as they may exist from time to time, to use or otherwise
exploit all trademarks, franchises, trade names, copyrights and patents of such
Borrower for the purpose of selling, leasing or otherwise disposing of any or
all Collateral following an Event of Default.

     The Borrowers jointly and severally represent and warrant to the Lender as
follows:

     Section 5.1  Corporate Existence and Power; Name; Chief Executive Office;
Inventory and Equipment Locations.  LDL is a corporation duly incorporated,
validly existing and in good standing under the laws of the State of Utah and
Sensar is a corporation duly incorporated, validly existing and in good standing
under the laws of the State of Utah, and each Borrower is duly licensed or
qualified to transact business in all jurisdictions where the character of the
property owned or leased or the nature of the business transacted by it makes
such licensing or qualification necessary.  Each Borrower has all requisite
power and authority, corporate or otherwise, to conduct its business, to own its
properties and to execute and deliver, and to perform all of its obligations
under, the Loan Documents.  During its corporate existence, each Borrower has
done business solely under the names set forth in Exhibit B hereto.  The chief
executive office and principal place of business of each Borrower is located at
the address set forth in Exhibit B hereto, and all of such Borrower's records
relating to its business or the Collateral are kept at that location.  All

locations set forth in Exhibit B hereto.

     Section 5.2  Authorization of Borrowing; No Conflict as to Law or
Agreements.  The execution, delivery and performance by each Borrower of the
Loan Documents and such Borrower's Guaranty and the borrowings from time to time
hereunder have been duly authorized by all necessary corporate action and do not
and will not (a) require any consent or approval of the stockholders of either
Borrower, (b) require any authorization, consent or approval by, or
registration, declaration or filing with, or notice to, any governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, or any third party, except such authorization, consent, approval,
registration, declaration, filing or notice as has been obtained, accomplished
or given prior to the date hereof, (c) violate any provision of any law, rule or
regulation (including, without limitation, Regulation X of the Board of
Governors of the Federal Reserve System) or of any order, writ, injunction or
decree presently in effect having applicability to either Borrower or of the
Articles of Incorporation or Bylaws of either Borrower, (d) result in a breach
of or constitute a default under any indenture or loan or credit agreement or
any other material agreement, lease or instrument to which either Borrower is a
party or by which it or its properties may be bound or affected, or (e) result
in, or require, the creation or imposition of any mortgage, deed of trust,
pledge, lien, security interest or other charge or encumbrance of any nature
(other than the Security Interests) upon or with respect to any of the
properties now owned or hereafter acquired by either Borrower.

     Section 5.3  Legal Agreements.  This Agreement constitutes and, upon due
execution by the Borrower executing the same, the other Loan Documents and such
Borrower's Guaranty will constitute, the legal, valid and binding obligations of
the Borrower executing the same, enforceable against such Borrower in accordance
with their respective terms.

     Section 5.4  Subsidiaries.  Except as set forth in Exhibit B attached
hereto the Borrowers have no Subsidiaries.

     Section 5.5  Financial Condition; No Adverse Change.  LD has heretofore
furnished to the Lender audited financial statements of LD for its fiscal year
ended June 30 1996, and those statements fairly present the financial condition
of LD and its Subsidiaries on the dates thereof and the results of their
operations and cash flows for the periods then ended, and were prepared in
accordance with generally accepted accounting principles.  Since the date of the
most recent financial statements, there has been no material adverse change in
the business, properties or condition (financial or otherwise) of LD or the
Borrowers.

     Section 5.6  Litigation.  There are no actions, suits or proceedings
pending or, to the knowledge of either Borrower, threatened against or affecting
either Borrower or any of its Affiliates or the properties of either Borrower or
any of its Affiliates before any court or governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign, which, if
determined adversely to such Borrower or any of its Affiliates, would have a
material adverse effect on the financial condition, properties or operations of
such Borrower or any of its Affiliates.

     Section 5.7  Regulation U.  Neither Borrower is engaged in the business of
extending credit for the purpose of purchasing or carrying margin stock (within
the meaning of Regulation U of the Board of Governors of the Federal Reserve
System), and no part of the proceeds of the Advance will be used to purchase or
carry any margin stock or to extend credit to others for the purpose of
purchasing or carrying any margin stock.

     Section 5.8  Taxes.  Each Borrower and each of its Affiliates have paid or
caused to be paid to the proper authorities when due all federal, state and
local taxes required to be withheld by each of them.  Each Borrower and each of
its Affiliates have filed all federal, state and local tax returns which to the
knowledge of the officers of such Borrower or any such Affiliate, as the case
may be, are required to be filed, and such Borrower and its Affiliates have paid
or caused to be paid to the respective taxing authorities all taxes as shown on
said returns or on any assessment received by any of them to the extent such
taxes have become due.

     Section 5.9  Titles and Liens.  Each Borrower has good and absolute title
to all Collateral described in the collateral reports provided to the Lender and
all other Collateral, properties and assets reflected in the latest balance
sheet referred to in Section 5.5 hereof and all proceeds thereof, free and clear
of all mortgages, security interests, liens and encumbrances, except for
mortgages, security interests and liens permitted by Section 7.1 hereof.  No
financing statement naming either Borrower as debtor is on file in any office
except to perfect only security interests permitted by Section 7.1 hereof.

     Section 5.10  Plans.  Except as disclosed to the Lender in writing prior to
the date hereof, neither Borrower nor any of its Affiliates maintains or has
maintained any Plan.  Neither Borrower nor any Affiliate of either Borrower has
received any notice or has any knowledge to the effect that it is not in full
compliance with any of the requirements of ERISA.  No Reportable Event or other
fact or circumstance which may have an adverse effect on the Plan's tax
qualified status exists in connection with any Plan.  Neither Borrower nor any
Affiliate of either Borrower has:

          (a)  Any accumulated funding deficiency within the meaning of ERISA;
     or

          (b)  Any liability or knows of any fact or circumstances which could
     result in any liability to the Pension Benefit Guaranty Corporation, the
     Internal Revenue Service, the Department of Labor or any participant in
     connection with any Plan (other than accrued benefits which or which may
     become payable to participants or beneficiaries of any such Plan).

     Section 5.11  Default.  Each Borrower is in compliance with all provisions
of all agreements, instruments, decrees and orders to which it is a party or by
which it or its property is bound or affected, the breach or default of which
could have a material adverse effect on the financial condition, properties or
operations of such Borrower.

     Section 5.12  Environmental Protection.  Each Borrower has obtained all
permits, licenses and other authorizations which are required under federal,
state and local laws and regulations relating to emissions, discharges, releases
of pollutants, contaminants, hazardous or toxic materials, or wastes into
ambient air, surface water, ground water or land, or otherwise relating to the
manufacture, processing, distribution, use, treatment, storage, disposal
transport or handling of pollutants, contaminants or hazardous or toxic
materials or wastes ("Environmental Laws") at such Borrower s facilities or in
connection with the operation of its facilities.  Except as previously disclosed
to the Lender in writing, each Borrower and all activities of such Borrower at
its facilities comply with all Environmental Laws and with all terms and
conditions of any required permits, licenses and authorizations applicable to
such Borrower with respect thereto.  Except as previously disclosed to the
Lender in writing, each Borrower is also in compliance with all limitations,
restrictions, conditions, standards, prohibitions, requirements, obligations
schedules and timetables contained in Environmental Laws or contained in any
plan order decree judgment or notice of which such Borrower is aware.  Except as
previously disclosed to the Lender in writing, neither Borrower is aware of, nor
has either Borrower received notice of any events, conditions, circumstances,
activities, practices, incidents, actions or plans which may interfere with or
prevent continued compliance with, or which may give rise to any liability
under, any Environmental Laws.

     Section 5.13  Submissions to Lender.  All financial and other information
provided to the Lender by or on behalf of a Borrower in connection with such
Borrower's request for the credit facilities contemplated hereby is true and
correct in all material respects and, as to projections, valuations or pro forma
financial statements, present a good faith opinion as to such projections,
valuations and pro forma condition and results.

     Section 5.14  Financing Statements.  Each Borrower has provided to the
Lender signed financing statements sufficient when filed to perfect the Security
Interests and the other security interests created by the Security Documents.
When such financing statements are filed in the offices noted therein, the
Lender will have a valid and perfected security interest in all Collateral and
all other collateral described in the Security Documents which is capable of
being perfected by filing financing statements.  None of the Collateral or other
collateral covered by the Security Documents is or will become a fixture on real
estate, unless a sufficient fixture filing is in effect with respect thereto.

     Section 5.15  Rights to Payment.  Each right to payment and each instrument
document, chattel paper and other agreement constituting or evidencing
Collateral or other collateral covered by the Security Documents is (or, in the
case of all future Collateral or such other collateral, will be when arising or
issued) the valid, genuine and legally enforceable obligation, subject to no
defense, setoff or counterclaim, of the account debtor or other obligor
obligated to pay such obligation.

                                   ARTICLE VI
                     Affirmative Covenants of the Borrowers

     related consolidated and consolidating statements of income, retained
     earnings and cash flows of LD and its Subsidiaries for the fiscal year then

     Section 6.2  Books and Records; Inspection and Examination.  Each Borrower
will keep accurate books of record and account for itself pertaining to the
Collateral and pertaining to such Borrower's business and financial condition
and such other matters as the Lender may from time to time request in which true
and complete entries will be made in accordance with generally accepted
accounting principles consistently applied and, upon request of the Lender, will
permit any officer, employee, attorney or accountant for the Lender (upon
reasonable notice unless the Lender in good faith believes that the accuracy of
the audit may be effected by notice) to audit, review, make extracts from or
copy any and all corporate and financial books and records of such Borrower at
all times during ordinary business hours, to send and discuss with account
debtors and other obligors requests for verification of amounts owed to such
Borrower, and to discuss the affairs of such Borrower with any of its directors.
Officers, employees or agents.  Each Borrower will permit the Lender, or its

or damage to which the Lender may be subjected as a result of any past, present
or future existence, use, handling, storage, transportation or disposal of any
hazardous waste or substance or toxic substance by the Borrower or on property
owned, leased or controlled by such Borrower.  This indemnification agreement
shall survive the termination of this Agreement and payment of the indebtedness
hereunder.

     Section 6.5  Payment of Taxes and Other Claims.  Each Borrower will pay or
discharge, when due, (a) all taxes, assessments and governmental charges levied
or imposed upon it or upon its income or profits, upon any properties belonging
to it (including, without limitation, the Collateral) or upon or against the
creation, perfection or continuance of the Security Interests, prior to the date
on which penalties attach thereto, (b) all federal, state and local taxes
required to be withheld by it, and (c) all lawful claims for labor, materials

properties of such Borrower; provided, that no Borrower shall be required to pay
any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings.

     Section 6.6  Maintenance of Properties.

          (a)  Each Borrower will keep and maintain the Collateral, the other
     collateral covered by the Loan Documents and all of its other properties
     necessary or useful in its business in good condition, repair and working
     order (normal wear and tear excepted) and will from time to time replace or
     repair any worn, defective or broken parts: provided, however, that nothing
     in this Section 6.6 shall prevent any Borrower from discontinuing the
     operation and maintenance of any of its properties if such discontinuance
     is, in the judgment of the Lender, desirable in the conduct of the
     Borrower's business and not disadvantageous in any material respect to the
     Lender.
     
          (b)  Each Borrower will defend the Collateral against all claims or
     demands of all persons (other than the Lender) claiming the Collateral or
     any interest therein.

          (c)  Each Borrower will keep all Collateral and other collateral
     covered by the Security Documents free and clear of all security interests,
     liens and encumbrances except the Security Interests and other security
     interests permitted by Section 7.1 hereof.

     Section 6.7  Insurance.  Each Borrower will obtain and at all times
maintain insurance with insurers believed by such Borrower to be responsible and
reputable, in such amounts and against such risks as may from time to time be
required by the Lender, but in all events in such amounts and against such risks
as is usually carried by companies engaged in similar business and owning
similar properties in the same general areas in which such Borrower operates.
Without limiting the generality of the foregoing, each Borrower will at all
times keep all tangible Collateral insured against risks of fire (including
so-called extended coverage), theft, collision (for Collateral consisting of
motor vehicles) and such other risks and in such amounts as the Lender may
reasonably request with any loss payable to the Lender to the extent of its
interest, and all policies of such insurance shall contain a lender's loss
payable endorsement for the benefit of the Lender.  All policies of liability
insurance required hereunder shall name the Lender as an additional insured.

     Section 6.8  Preservation of Corporate Existence.  Each Borrower will
preserve and maintain its corporate existence and all of its rights, privileges
and franchises necessary or desirable in the normal conduct of its business and
shall conduct its business in an orderly, efficient and regular manner.

     Section 6.9  Delivery of Instruments etc.  Upon request by the Lender, each
Borrower will promptly deliver to the Lender in pledge all instruments,
documents and chattel papers constituting Collateral, duly endorsed or assigned
by such Borrower.

     Section 6.10  Lockbox; Collateral Account.  (a) Until the Lender directs a
Borrower to establish a lockbox pursuant hereto, each Borrower will irrevocably
direct all present and future Account debtors and other Persons obligated to
make payments constituting Collateral to make such payments by wire transfer
directly to the Collateral Account established for such Borrower.  Following the
establishment of a Lockbox for a Borrower, each Borrower will irrevocably direct
all present and future Account debtors and other persons obligated to make
payments constituting Collateral to make such payments by wire transfer directly
to the Collateral Account established for such Borrower or to such Borrower's
Lockbox.  All of such Borrower's invoices, account statements and other written
or oral communications directing, instructing, demanding or requesting payment
of any Account or any other amount constituting Collateral shall conspicuously
direct that all payments be made in accordance with the requirements of this
Section 6.10 and shall include wire transfer instructions and, if established,
the Lockbox address.  All payments received in a Borrower's Lockbox shall be
processed to the Collateral Account established for such Borrower.

          (b)  Each Borrower agrees to deposit in the Collateral Account or, at
     the Lender's option, to deliver to the Lender all collections on Accounts,
     contract rights, chattel paper and other rights to payment constituting
     Collateral, and all other cash proceeds of Collateral, which such Borrower
     may receive directly, immediately upon receipt thereof, in the form
     received, except for such Borrower's endorsement when deemed necessary.
     Until delivered to the Lender or deposited in the Collateral Account, all
     proceeds or collections of Collateral shall be held in trust by such
     Borrower for and as the property of the Lender and shall not be commingled
     with any funds or property of such Borrower.  Amounts deposited in the
     Collateral Account of a Borrower shall not bear interest and shall not be
     subject to withdrawal by such Borrower, except after full payment and
     discharge of all Obligations of such Borrower.  All such collections shall
     constitute proceeds of Collateral and shall not constitute payment of any
     Obligation of such Borrower.  Collected funds from the Collateral Account
     of a Borrower shall be transferred to the Lender's general account, and the
     Lender may deposit in its general account or in such Collateral Account any
     and all collections received by it directly from such Borrower.  The Lender
     may commingle such funds with other property of the Lender or any other
     person.  The Lender from time to time shall, upon initiation by such
     Borrower, after allowing one Banking Day, apply such funds to the payment
     of any and all Obligations of such Borrower, in any order or manner of
     application satisfactory to the Lender.  All items delivered to the Lender
     or deposited in the Collateral Account of a Borrower shall be subject to
     final payment.  If any such item is returned uncollected, such Borrower
     will immediately pay the Lender, or, for items deposited in the Collateral
     Account of a Borrower, the bank maintaining such account, the amount of
     that item, or such bank at its discretion may charge any uncollected item
     to such Borrower's commercial account or other account.  Such Borrower
     shall be liable as an endorser on all items deposited in the Collateral
     Account, whether or not in fact endorsed by such Borrower.

     Section 6.11  Performance by the Lender.  If either Borrower at any time
fails to perform or observe any of the foregoing covenants contained in this
Article VI or elsewhere herein, and if such failure shall continue for a period
of ten calendar days after the Lender gives such Borrower written notice thereof
(or in the case of the agreements contained in Sections 6.5, 6.7 and 6.10
hereof, immediately upon the occurrence of such failure, without notice or lapse
of time), the Lender may, but need not, perform or observe such covenant on
behalf and in the name, place and stead of the Borrowers (or, at the Lender's
option, in the Lender's name) and may, but need not, take any and all other
actions which the Lender may reasonably deem necessary to cure or correct such
failure (including, without limitation, the payment of taxes, the satisfaction
of security interests, liens or encumbrances, the performance of obligations
owed to account debtors or other obligors, the procurement and maintenance of
insurance, the execution of assignments, security agreements and financing
statements, and the endorsement of instruments); and the Borrowers shall
thereupon jointly and severally pay to the Lender on demand the amount of all
monies expended and all costs and expenses (including reasonable attorneys' fees
and legal expenses) incurred by the Lender in connection with or as a result of
the performance or observance of such agreements or the taking of such action by
the Lender together with interest thereon from the date expended or incurred at
the default rate of interest payable on the Term Note.  To facilitate the
performance or observance by the Lender of such covenants of the Borrowers, each
Borrower hereby irrevocably appoints the Lender, or the delegate of the Lender,
acting alone, as the attorney in fact of such Borrower (which appointment is
coupled with an interest) with the right (but not the duty) from time to time to
create, prepare, complete, execute, deliver, endorse or file in the name and on
behalf of such Borrower any and all instruments, documents, assignments,
security agreements, financing statements, applications for insurance and other
agreements and writings required to be obtained, executed, delivered or endorsed
by such Borrower under this Section 6.11.

sale of equity securities to LD during such fiscal year, or (ii) the amount of
any capital contributions from LD to the Borrowers during such fiscal year.
Prior to June 30, 1997, the Borrowers and the Lender shall negotiate in good
faith as to the limitations on capital expenditures for periods after such date,
but if the Borrowers and the Lender do not agree, the Lender may designate
capital expenditures limitations in its sole discretion, and the failure of the
Borrowers to maintain their capital expenditures within such limitations shall
be a default hereunder.

principles.  Neither Borrower will adopt, permit or consent to any change in its
fiscal year.

Lender, grant any discount, credit or allowance to any customer of such Borrower
or accept any return of goods sold, or at any time (whether before after notice
from the Lender) modify, amend, subordinate, cancel or terminate the obligation
of any account debtor or other obligor of such Borrower.

     Section 7.13  Defined Benefit Pension Plans.  Neither Borrower will adopt,
create, assume or become a party to any defined benefit pension plan, unless
disclosed to the Lender pursuant to Section 5.10 hereof.

     Section 7.14  Other Defaults.  Neither Borrower will permit any breach,
default or event of default to occur under any note loan agreement, indenture,
lease, mortgage, contract for deed, security agreement or other contractual
obligation binding upon such Borrower.

chief executive office or principal place of business or move, relocate, close
or sell any business location.  Neither Borrower will permit any tangible

covering such Collateral would be required to be, but has not in fact been,
filed in order to perfect the Security Interests.  Neither Borrower will change
its name.

     Section 7.16  Organizational Documents.  Neither Borrower will amend its
certificate of incorporation, articles of incorporation or bylaws.

     Agreement shall prove to have been incorrect in any material respect when
     deemed to be effective; or

     applicable period of grace, if any, specified in such evidence of
     indebtedness, indenture, other instrument or lease; or

     might constitute grounds for the termination of any Plan or for the

     ERISA; or either Borrower shall have failed to make any quarterly
     contribution required with respect to any Plan under Section 412(m) of the
     Internal Revenue Code of 1986, as amended, which the Lender determines in
     good faith may by itself, or in combination with any such failures that the
     Lender may determine are likely to occur in the future, result in the
     imposition of a lien on the assets of either Borrower in favor of the Plan;
     or

          (j)  An event of default shall occur under any Loan Document or under
     any other security agreement, mortgage, deed of trust, assignment or other
     instrument or agreement securing any obligations of either Borrower
     hereunder or under any note; or

          (k)  Either Borrower or LD shall liquidate, dissolve, terminate or
     suspend its business operations or otherwise fail to operate its business
     in the ordinary course, or sell all or substantially all of its assets.
     without the prior written consent of the Lender; or

          (l)  Either Borrower or LD shall fail to pay, withhold, collect or
     remit any tax or tax deficiency when assessed or due (other than any tax
     deficiency which is being contested in good faith and by proper proceedings
     and for which it shall have set aside on its books adequate reserves
     therefor) or notice of any state or federal tax liens shall be filed or
     issued; or

          (m)  Default in the payment of any amount owed by either Borrower to

     Affiliate under any agreement between such Affiliate and the Lender and the
     expiration of the applicable grace period, if any, with respect thereto.

     Section 8.2  Rights and Remedies.  Upon the occurrence of an Event of
Default or at any time thereafter, the Lender may exercise any or all of the
following rights and remedies:

          (a)  The Lender may, by notice to the Borrowers, declare the Credit
     Facility to be terminated, whereupon the same shall forthwith terminate.

          (b)  The Lender may, by notice to the Borrowers, declare to be
     forthwith due and payable the entire unpaid principal amount of the Notes
     then outstanding, all interest accrued and unpaid thereon, all amounts
     payable under this Agreement and any other Obligations, whereupon such
     Notes, all such accrued interest and all such amounts and Obligations shall
     become and be forthwith due and payable, without presentment, notice of
     dishonor, protest or further notice of any kind, all of which are hereby
     expressly waived by the Borrowers;
     
          (c)  The Lender may, without notice to the Borrowers and without
     further action, apply any and all money owing by the Lender to either
     Borrower to the payment of the Advances, including interest accrued
     thereon, and of all other sums then owing by the Borrowers hereunder;

          (d)  The Lender may, exercise and enforce any and all rights and
     remedies available upon default to a secured party under the UCC,
     including, without limitation, the right to take possession of Collateral,
     or any evidence thereof, proceeding without judicial process or by judicial
     process (without a prior hearing or notice thereof, which the Borrowers
     hereby expressly waive) and the right to sell, lease or otherwise dispose
     of any or all of the Collateral, and, in connection therewith, the
     Borrowers will on demand assemble the Collateral and make it available to
     the Lender at a place to be designated by the Lender which is reasonably
     convenient to both parties;

          (e)  the Lender may exercise and enforce its rights and remedies under
     the Loan Documents; and

          (f)  the Lender may exercise any other rights and remedies available
     to it by law or agreement.

Notwithstanding the foregoing, upon the occurrence of an Event of Default
described in Section 8.1(e) hereof, the entire unpaid principal amount of the
Note, all interest accrued and unpaid thereon, all other amounts payable under
this Agreement and any other Obligations shall be immediately due and payable
automatically without presentment, demand, protest or notice of any kind.

     Section 8.3  Certain Notices.  If notice to either Borrower of any intended
disposition of Collateral or any other intended action is required by law in a
particular instance, such notice shall be deemed commercially reasonable if
given (in the manner specified in Section 9.3) at least ten calendar days prior
to the date of intended disposition or other action.

                                   ARTICLE IX
                                 Miscellaneous

     Section 9.1  No Waiver; Cumulative Remedies.  No failure or delay on the
part of the Lender in exercising any right, power or remedy under the Loan
Documents shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right, power or remedy preclude any other or further
exercise thereof or the exercise of any other right, power or remedy under the
Loan Documents.  The remedies provided in the Loan Documents are cumulative and
not exclusive of any remedies provided by law.

     Section 9.2  Amendments, Etc.  No amendment, modification, termination or
waiver of any provision of any Loan Document or consent to any departure by the
Borrowers therefrom or any release of a Security Interest shall be effective
unless the same shall be in writing and signed by the Lender, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.  No notice to or demand on a Borrowers in any
case shall entitle either Borrower to any other or further notice or demand in
similar or other circumstances.

     Section 9.3  Addresses for Notices, Etc.  Except as otherwise expressly
provided herein, all notices, requests, demands and other communications
provided for under the Loan Documents shall be in writing and shall be (a)

     Norwest Business Credit, Inc.
     1740 Broadway
     Denver, Colorado 80274-8625

     Section 9.5  Further Documents.  The Borrowers will from time to time
execute and deliver or endorse any and all instruments, documents, conveyances,
assignments, security agreements, financing statements and other agreements and
writings that the Lender may reasonably request in order to secure, protect,
perfect or enforce the Security Interests or the rights of the Lender under this
Agreement (but any failure to request or assure that any Borrower executes,
delivers or endorses any such item shall not affect or impair the validity,
sufficiency or enforceability of this Agreement and the Security Interests,
regardless of whether any such item was or was not executed, delivered or
endorsed in a similar context or on a prior occasion).

     Section 9.6  Collateral.  This Agreement does not contemplate a sale of
accounts, contract rights or chattel paper, and, as provided by law, the
Borrowers are entitled to any surplus and shall remain liable for any
deficiency.  The Lender's duty of care with respect to Collateral in its
possession (as imposed by law) shall be deemed fulfilled if it exercises
reasonable care in physically keeping such Collateral, or in the case of
Collateral in the custody or possession of a bailee or other third person,
exercises reasonable care in the selection of the bailee or other third person,
and the Lender need not otherwise preserve, protect, insure or care for any
Collateral.  The Lender shall not be obligated to preserve any rights the
Borrowers may have against prior parties, to realize on the Collateral at all or
in any particular manner or order or to apply any cash proceeds of the
Collateral in any particular order of application.

     Section 9.7  Costs and Expenses.  The Borrowers jointly and severally agree
to pay on demand all costs and expenses, including (without limitation)
attorneys' fees incurred by the Lender in connection with the Obligations, this
Agreement, the Loan Documents and any other document or agreement related hereto
or thereto, and the transactions contemplated hereby, including without
limitation all such costs, expenses and fees incurred in connection with the
negotiation, preparation, execution, amendment, administration, performance,
collection and enforcement of the Obligations and all such documents and
agreements and the creation, perfection, protection, satisfaction, foreclosure
or enforcement of the Security Interests.

     Section 9.8  Indemnity.  In addition to the payment of expenses pursuant to
Section 9.7 hereof and the environmental indemnity pursuant to Section 6.4
hereof, the Borrowers jointly and severally agree to indemnify, defend and hold
harmless the Lender, and any of its participants, parent corporations,
subsidiary corporations, affiliated corporations, successor corporations, and
all present and future officers, directors, employees and agents of the
foregoing (the "Indemnitees"), from and against (i) any and all transfer taxes
documentary taxes, assessments or charges made by any governmental authority by
reason of the execution and delivery of this Agreement and the other Loan
Documents or the making of the Advance, and (ii) any and all liabilities,
losses, damages, penalties, judgments, suits, claims, costs and expenses of any
kind or nature whatsoever (including, without limitation, the reasonable fees
and disbursements of counsel) in connection with any investigative,
administrative or judicial proceedings, whether or not such Indemnitee shall be
designated a party thereto, which may be imposed on, incurred by or asserted
against such Indemnitee, in any manner relating to or arising out of or in
connection with the making of the Advance, this Agreement and all other Loan
Documents or the use or intended use of the proceeds of the Advance (the
"Indemnified Liabilities").  If any investigative, judicial or administrative
proceeding arising from any of the foregoing is brought against any Indemnitee,
upon request of such Indemnitee, the Borrowers, or counsel designated by the
Borrowers and satisfactory to the Indemnitee, will resist and defend such
action, suit or proceeding to the extent and in the manner directed by the
Indemnitee, at the Borrowers' sole cost and expense.  Each Indemnitee will use
its best efforts to cooperate in the defense of any such action, suit or
proceeding.  If the foregoing undertaking to indemnify, defend and hold harmless
may be held to be unenforceable because it violates any law or public policy,
the Borrowers shall nevertheless make the maximum contribution to the payment
and satisfaction of each of the Indemnified Liabilities which is permissible
under applicable law.  The obligation of the Borrowers under this Section 9.8
shall survive the termination of this Agreement and the discharge of the
Borrowers' other Obligations.

     Section 9.9  Participants.  The Lender and its participants, if any, are
not partners or joint venturers, and the Lender shall not have any liability or
responsibility for any obligation, act or omission of any of its participants.
All rights and powers specifically conferred upon the Lender may be transferred
or delegated to any of the participants, successors or assigns of the Lender.

     Section 9.10  Execution in Counterparts.  This Agreement and other Loan
Documents may be executed in any number of counterparts, each of which when so
executed and delivered shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same instrument.

     Section 9.11  Binding Effect; Assignment; Complete Agreement.  The Loan
Documents shall be binding upon and inure to the benefit of the Borrowers and
the Lender and their respective successors and assigns, except that neither
Borrower shall have the right to assign its rights thereunder or any interest
therein without the prior written consent of the Lender.  This Agreement,
together with the Loan Documents, comprises the complete and integrated
agreement of the parties on the subject matter hereof and supersedes all prior
agreements, written or oral, on the subject matter hereof.

     Section 9.12  Governing Law; Jurisdiction, Venue; Waiver of Jury Trial.
The Loan Documents shall be governed by and construed in accordance with the
substantive laws (other than conflict laws) of the State of Colorado.  Each
party consents to the personal jurisdiction of the state and federal courts
located in the State of Colorado in connection with any controversy related to
this Agreement, waives any argument that venue in any such forum is not
convenient and agrees that any litigation initiated by any of them in connection
with this Agreement shall be venued in either the District Court of the City and
County of Denver, Colorado, or the United States District Court, District of
Colorado.  The parties waive any right to trial by jury in any action or
proceeding based on or pertaining to this Agreement.

     Section 9.13  Severability of Provisions.  Any provision of this Agreement
which is prohibited or unenforceable shall be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
hereof.

     Section 9.14  Headings.  Article and Section headings in this Agreement are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers "hereunto duly authorized as of the date
first above written.
