                       LECTEC CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    QUARTERS ENDED DECEMBER 31, 1999 AND 1998
                                   (UNAUDITED)

(1) GENERAL

         The accompanying consolidated financial statements include the accounts
of LecTec Corporation (the "Company") and LecTec International Corporation, a
wholly-owned subsidiary which was dissolved and merged into LecTec Corporation
on December 31, 1999. All significant intercompany balances and transactions
have been eliminated in consolidation. The Company's financial statements for
the three months and six months ended December 31, 1999 should be read in
conjunction with its Annual Report on Form 10-K and its Annual Report to
Shareholders for the fiscal year ended June 30, 1999. The interim financial
statements are unaudited and in the opinion of management, reflect all
adjustments necessary for a fair presentation of results for the periods
presented. Results for interim periods are not necessarily indicative of results
for the year.

(2) NET LOSS

         The Company's basic net loss per share amounts have been computed by
dividing net loss by the weighted average number of outstanding common shares.
The Company's diluted net loss per share amounts have been computed by dividing
net loss by the weighted average number of outstanding common shares and common
share equivalents, when dilutive. Options and warrants to purchase 1,044,003 and
873,066 shares of common stock with a weighted average exercise price of $6.20
and $7.70 were outstanding during the three months ended December 31, 1999 and
1998, but were excluded because they were antidilutive. Options and warrants to
purchase 1,093,443 and 870,323 shares of common stock with a weighted average
exercise price of $6.35 and $7.72 were outstanding during the six months ended
December 31, 1999 and 1998, but were excluded because they were antidilutive.

(3) COMPREHENSIVE LOSS

         For the quarter and six months ended December 31, 1999 and 1998, there
were no items which the Company is required to recognize as components of
comprehensive income (loss), therefore comprehensive loss was the same as net
loss.

(4) SEGMENTS

         The Company operates its business in one reportable segment - the
manufacture and sale of products based on advanced skin interface technologies.
Each of the Company's major product lines has similar economic characteristics,
technology, manufacturing processes, and regulatory environments. Customers and
distribution and marketing strategies vary within major product lines as well as
overlap between major product lines. The Company's executive decision makers
evaluate sales performance based on the total sales of each major product line
and profitability on a total company basis, due to shared infrastructures, to
make operating and strategic decisions. Net sales by major product line were as
follows:

Three months ended December 31,           1999          1998

(5) LINE OF CREDIT AND LIQUIDITY

         In November 1999, the Company finalized a $2,000,000 line of credit
which expires in November 2001. The line of credit is secured by the Company's
receivables, inventory and equipment, and bears interest at the lending bank's
prime rate plus three percentage points. There were no borrowings outstanding on
the line of credit as of December 31, 1999, nor during the three months then
ending. The credit agreement contains certain restrictive covenants which
require the Company to maintain, among other things, specified levels of net
worth and not to exceed specified cumulative losses. Defaults by the Company on
certain financial covenants as of November 30 and December 31, 1999 were waived
by the bank in February 2000 and the line of credit agreement was amended to
adjust specified levels of these covenants for the months ending January 31 and
February 29, 2000.

         The Company experienced negative cash flow from operations of $737,110
for the six months ending December 31, 1999. This cash requirement was satisfied
principally from existing cash balances. Management believes that internally
generated cash flow and the new line of credit will be sufficient to support
operating requirements in the near term.

(6) STOCK REPURCHASE PROGRAM

         In April 1998, the Company's Board of Directors authorized a stock
repurchase program pursuant to which up to 500,000 shares, or approximately
12.4% of the Company's outstanding common stock, may be repurchased. The shares
may be purchased from time to time through open market transactions, block
purchases, tender offers, or in privately negotiated transactions. The total
consideration for all shares repurchased under this program cannot exceed
$2,000,000. During the quarter ended December 31, 1999 no shares were
repurchased and during the quarter ended December 31, 1998, 74,800 shares were
repurchased for $223,663. During the six months ended December 31, 1999 no
shares were repurchased and during the six months ended December 31, 1998,
165,650 shares were repurchased for $524,338. Through December 31, 1999 the
Company has repurchased a total of 205,150 shares at a cost of $667,963 under
this program.

(7) EMPLOYEE STOCK PURCHASE PLAN

         The Company's employee stock purchase plan, adopted November 19, 1998,
allows eligible employees to purchase shares of the Company's common stock
through payroll deductions. The purchase price is the lower of 85% of the fair
market value of the stock on the first or last day of each six-month period
during which an employee participated in the plan. The Company has reserved
200,000 shares under the plan of which 14,018 shares were purchased by employees
for $26,815 during the first six months of fiscal 2000. As of December 31, 1999
employees have purchased a total of 29,144 shares for $59,821.

PART I - FINANCIAL INFORMATION
ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

QUARTERS AND SIX MONTHS ENDED DECEMBER 31, 1999 AND 1998

RESULTS OF OPERATIONS

         Net sales for the second quarter of fiscal 2000 were $3,299,705
compared to net sales of $3,103,277 for the second quarter of fiscal 1999, an
increase of 6.3%. The increase was primarily the result of increased therapeutic
consumer product sales which more than offset decreased medical tape and
conductive product sales. Therapeutic consumer product sales increased by 114.0%
from $429,715 to $919,555 while conductive product sales, the Company's largest
product group, decreased slightly by 1.4% and medical tape product sales
decreased by 37.0%. The therapeutic consumer product sales increase was
primarily the result of increased TheraPatch(R) sales volume, especially
TheraPatch Vapor products. The decrease in medical tape product sales was
primarily due to the absence of sales to a former low-margin slit roll tape
customer and decreases in sales volume to several other low-margin medical tape
customers.

         Net sales for the first six months of fiscal 2000 were $6,308,457
compared to net sales of $6,006,334 for the first six months of fiscal 1999, an
increase of 5.0%. The increase was primarily the result of increased therapeutic
consumer product sales which more than offset decreased medical tape and
conductive product sales. Therapeutic consumer product sales increased by 192.1%
from $610,343 to $1,782,734 while conductive product sales, the Company's
largest product group, decreased by 10.8% and medical tape product sales
decreased by 30.4%. The therapeutic consumer product sales increase was
primarily the result of increased TheraPatch sales volume, especially TheraPatch
Vapor products. The conductive product sales decrease was primarily the result
of the absence of sales to a former customer who began manufacturing their own
product in the fourth quarter of fiscal 1999. Sales to the former customer in
the first six months of fiscal 1999 were approximately $338,000. Medical tape
product sales decreased primarily due to reduced sales to a low-margin slit roll
tape customer and decreases in sales volume to several other low-margin medical
tape customers.

         Gross profit for the second quarter of fiscal 2000 was $1,063,014
compared to $925,738 for the second quarter of fiscal 1999, an increase of
14.8%. Gross profit as a percent of net sales for the second quarter of fiscal
2000 was 32.2% compared to 29.8% for the second quarter of fiscal 1999. The
increase in gross profit for the quarter resulted primarily from the favorable
impact of a change in the sales mix toward higher-margin therapeutic consumer
products and increased sales volume which more than offset increased labor
costs. Labor costs were higher in the current quarter primarily due to an
increase in staffing levels and overtime related to the production of
therapeutic patch products.

         Gross profit for the first six months of fiscal 2000 was $2,002,295
compared to $1,942,991 for the first six months of fiscal 1999, an increase of
3.1%. Gross profit as a percent of net sales for the first six months of fiscal
2000 was 31.7% compared to 32.3% for the first six months of fiscal 1999. The
increase in gross profit dollars for the six months resulted primarily from the
favorable impact of a change in the sales mix toward higher-margin therapeutic
consumer products which more than offset increased labor, depreciation, and
repairs and maintenance expense. Labor costs were higher in the current six
months primarily due to an increase in staffing levels and overtime related to
the production of therapeutic patch products.

         Sales and marketing expenses were $863,655 and $545,938 during the
second quarters of fiscal 2000 and 1999, and as a percentage of net sales, were
26.2% and 17.6%. The increase in sales and marketing expense for the quarter was
primarily due to increased cooperative and media advertising expenses and retail
slotting fees related to sales of the TheraPatch product line. The Company
anticipates that sales and marketing expenses as a percent of sales for the
remainder of fiscal 2000 will

be comparable to the second quarter of fiscal 2000 due to marketing programs
associated with the TheraPatch product line.

         Sales and marketing expenses were $1,598,700 and $879,471 during the
first six months of fiscal 2000 and 1999, and as a percentage of net sales, were
25.3% and 14.6%. The increase in sales and marketing expense for the first six
months was primarily due to increased retail slotting fees and advertising
expenses related to the TheraPatch product line.

         General and administrative expenses were $688,783 and $781,630 during
the second quarters of fiscal 2000 and 1999, and as a percentage of net sales,
were 20.9% and 25.2%. The decrease in general and administrative expenses for
the quarter was primarily due to decreased legal expenses. Legal expenses in the
prior year quarter included approximately $126,000 of expenses associated with
the re-negotiation and modification of the license agreement for the development
and commercialization of cotinine.

         General and administrative expenses were $1,247,873 and $1,368,091
during the first six months of fiscal 2000 and 1999, and as a percentage of net
sales, were 19.8% and 22.8%. The decrease in general and administrative expenses
for the first six months of fiscal 2000 was primarily due to decreased legal
expenses.

         Research and development expenses for the second quarters of fiscal
2000 and 1999 were $310,202 and $286,025, and as a percentage of net sales, were
9.4% and 9.2%. The increase in research and development expense for the current
quarter primarily reflects increased labor costs of personnel working on
therapeutic consumer products under development.

         Research and development expenses for the first six months of fiscal
2000 and 1999 were $579,964 and $566,038, and as a percentage of net sales, were
9.2% and 9.4%. The increase in research and development expense for the first
six months of fiscal 2000 primarily reflects increased labor costs which were
partially offset by a decrease in test-run production costs.

         Other income, net, decreased in the second quarter of fiscal 2000 to
$4,459 from $26,987 in the second quarter of fiscal 1999. Other income, net,
decreased in the first six months of fiscal 2000 to $25,793 from $58,788 in the
first six months of fiscal 1999. Both of the fiscal 2000 decreases were
primarily the result of decreased interest income due to lower cash and cash
equivalent balances.

         The Company recorded a loss before income taxes of $795,167 in the
second quarter of fiscal 2000 compared to a loss before income taxes of $660,868
for the second quarter of fiscal 1999. The Company recorded a loss before income
taxes of $1,398,449 in the first six months of fiscal 2000 compared to a loss
before income taxes of $811,821 for the first six months of fiscal 1999. The
increased loss in the current year second quarter and first six months was
primarily the result of increased sales and marketing expenses related to retail
sales of the Company's TheraPatch products. The increased sales and marketing
expenses more than offset an increase in gross profit that resulted from a shift
in the sales mix toward higher-margin therapeutic consumer products. The Company
expects to incur similar losses for the remainder of fiscal 2000 as it continues
to incur increased sales and marketing expenses related to retail sales of
TheraPatch consumer products.

         The Company recorded no income tax expense or benefit in the second
quarter and first six months of fiscal 2000 compared to nominal income tax
expense in the second quarter and first six months of the prior year. There was
no income tax benefit recorded during the second quarter and first six months of
fiscal 2000 since the loss benefit may not be realizable by the Company. Income
tax expense in the second quarter and first six months of fiscal 1999 reflects
minimal tax expense associated with the Company's foreign sales corporation
subsidiary.

         Inflation has not had a significant impact on the Company's operations
or cash flow.

LIQUIDITY AND CAPITAL RESOURCES

         Cash and cash equivalents decreased by $1,001,534 to $20,491 during the
first six months of fiscal 2000. Accounts receivable decreased by $385,280 to
$1,966,265 primarily due to a reduction in accounts more than 60 days old.
Inventories increased by $151,339 to $2,147,863 primarily due to increased raw
materials inventory related to therapeutic products which was partially offset
by decreased finished goods inventory of medical tape. Accounts payable of
$1,678,195 at December 31, 1999 were virtually unchanged during the first six
months of fiscal 2000. Capital spending for manufacturing equipment and plant
improvements totaled $247,204 during the first six months of fiscal 2000. There
were no material commitments for capital expenditures at December 31, 1999.

         The Company had working capital of $2,282,744 and a current ratio of
1.9 at December 31, 1999 compared to working capital of $3,471,715 and a current
ratio of 2.4 at June 30, 1999.

         There was no short or long-term debt outstanding at December 31, 1999
or June 30, 1999. The Company finalized a $2,000,000 asset-based line of credit
on November 22, 1999. There were no advances under this line of credit during
the period from November 22, 1999 through December 31, 1999. As of January 31,
2000, the Company had total borrowings outstanding on the line of credit of
$180,021. Defaults by the Company on certain financial covenants as of November
30 and December 31, 1999 were waived by the bank in February 2000 and the line
of credit agreement was amended to adjust specified levels of financial
covenants 6.12 and 6.13 for the months ending January 31 and February 29, 2000.

         Management believes that internally-generated cash flow and the new
secured line of credit will be sufficient to support anticipated operating
requirements during the remainder of fiscal 2000. Management is currently
evaluating additional sources of capital that may be required to support
longer-term growth and expansion of the business. Maintaining adequate levels of
working capital depends in part upon the success of the Company's products in
the marketplace, the relative profitability of those products and the Company's
ability to control operating expenses. Funding of the Company's operations in
future periods may require additional investments in the Company in the form of
equity or debt. There can be no assurance that the Company will achieve desired
levels of sales or profitability, or that future capital infusions will be
available.

IMPACT OF THE YEAR 2000 ISSUE

         The Year 2000 ("Y2K") issue is the result of computer systems using a
two-digit format, as opposed to four digits, to indicate the year. Such computer
systems may be unable to interpret dates beyond the year 1999, which could cause
a system failure or other computer errors, leading to disruptions in operations.
A number of other date issues (e.g., incorrect handling of leap years) may also
cause problems. All of these issues are collectively referred to as Y2K. In
fiscal 1998, the Company developed a comprehensive program for Y2K compliance
consisting of two parts: internal systems compliance and third party compliance.
This program was described in the Company's Form 10-K for fiscal 1999 and Form
10-Q for the first quarter of fiscal 2000. All phases of the Y2K compliance
program were completed prior to December 31, 1999.

         The Company has not experienced any Y2K related problems with its
internal systems nor has there been any disruption of supplies or services from
third parties. However, because the Company's continued Y2K compliance in
calendar 2000 is in part dependent on the continued Y2K compliance of third
parties, there can be no assurance that the Company's efforts alone have
resolved all Y2K issues or that key third parties will not experience Y2K
compliance failures as calendar year 2000 progresses.

         All costs for Y2K compliance have been expensed in the period incurred
and have been paid from operating funds. The Company does not specifically track
internal staff time spent on the Y2K issue, however, it has included an estimate
of the cost of this time in the estimated total costs. The Company


                                      I-9
<PAGE>


estimates the total costs for both the internal systems compliance program and
the third party compliance program through December 31, 1999 were approximately
$25,000 and does not expect to incur additional costs.

         Development of unforseen Y2K complications and the Company's ability to
deal with them continue to pose some risk and uncertainty which could result in,
among other things, business disruption, operation problems, financial loss,
legal liability and similar adverse consequences.


FORWARD-LOOKING STATEMENTS

         From time to time, in reports filed with the Securities and Exchange
Commission (including this Form 10-Q), in press releases, and in other
communications to shareholders or the investment community, the Company may
provide forward-looking statements concerning possible or anticipated future
results of operations or business developments which are typically preceded by
the words "believes", "expects", "anticipates", "intends", "will", "may",
"should" or similar expressions. Such forward-looking statements are subject to
risks and uncertainties which could cause results or developments to differ
materially from those indicated in the forward-looking statements. Such risks
and uncertainties include, but are not limited to, the buying patterns of major
customers; competitive forces including new products or pricing pressures; costs
associated with and acceptance of the Company's TheraPatch brand strategy;
impact of interruptions to production; dependence on key personnel; need for
regulatory approvals; changes in governmental regulatory requirements or
accounting pronouncements, unforeseen Y2K complications and third party
disruptions; and ability to satisfy funding requirements for operating needs,
expansion or capital expenditures.

PART I  - FINANCIAL INFORMATION
ITEM 3  - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company has no history of, and does not anticipate in the future,
investing in derivative financial instruments, derivative commodity instruments
or other such financial instruments. Transactions with international customers
are entered into in U.S. dollars, precluding the need for foreign currency
hedges. Additionally, the Company invests in money market funds and short-term
commercial paper, which experience minimal volatility. Thus, the exposure to
market risk is not material.

Revolving Advances shall be evidenced by the Revolving Note and shall be secured
by the Collateral as provided in Article III. Within the limits set forth in
this Section 2.1, the Borrower may borrow, prepay pursuant to Section 2.10 and
reborrow. The Borrower agrees to comply with the following procedures in
requesting Revolving Advances under this Section 2.1:


                                        9
<PAGE>


            (a) The Borrower shall make each request for a Revolving Advance to
      the Lender before 11:00 a.m. (Minneapolis time) of the day of the
      requested Revolving Advance. Requests may be made in writing or by
      telephone, specifying the date of the requested Revolving Advance and the
      amount thereof. Each request shall be by (i) any officer of the Borrower;
      or (ii) any person designated as the Borrower's agent by any officer of
      the Borrower in a writing delivered to the Lender; or (iii) any person
      whom the Lender reasonably believes to be an officer of the Borrower or
      such a designated agent.

            (b) Upon fulfillment of the applicable conditions set forth in
      Article IV, the Lender shall disburse the proceeds of the requested
      Revolving Advance by crediting the same to the Borrower's demand deposit
      account maintained with Norwest Bank unless the Lender and the Borrower
      shall agree in writing to another manner of disbursement. Upon the
      Lender's request, the Borrower shall promptly confirm each telephonic
      request for an Advance by executing and delivering an appropriate
      confirmation certificate to the Lender. The Borrower shall repay all
      Advances even if the Lender does not receive such confirmation and even if
      the person requesting an Advance was not in fact authorized to do so. Any
      request for an Advance, whether written or telephonic, shall be deemed to
      be a representation by the Borrower that the conditions set forth in
      Section 4.2 have been satisfied as of the time of the request.

            Section 2.2 Letters of Credit.

            (a) The Lender agrees, on the terms and subject to the conditions
      herein set forth, to cause an Issuer to issue, from the Funding Date to
      the Termination Date, one or more irrevocable standby or documentary
      letters of credit (each, a "Letter of Credit") for the Borrower's account.
      The Lender shall have no obligation to cause an Issuer to issue any Letter
      of Credit if the face amount of the Letter of Credit to be issued would
      exceed the lessor of:

                  (i) $250,000 less the L/C Amount, or

                  (ii) the Borrowing Base less the sum of (A) all outstanding
            and unpaid Revolving Advances and (B) the L/C Amount.

      Each Letter of Credit, if any, shall be issued pursuant to a separate L/C
      Application entered into by the Borrower and the Lender for the benefit of
      the Issuer, completed in a manner satisfactory to the Lender and the
      Issuer. The terms and conditions set forth in each such L/C Application
      shall supplement the terms and conditions hereof, but if the terms of any
      such L/C Application and the terms of this Agreement are inconsistent, the
      terms hereof shall control.

            (b) No Letter of Credit shall be issued with an expiry date later
      than the Termination Date in effect as of the date of issuance.


                                       10
<PAGE>


            (c) Any request to cause an Issuer to issue a Letter of Credit under
      this Section 2.2 shall be deemed to be a representation by the Borrower
      that the conditions set forth in Section 4.2 have been satisfied as of the
      date of the request.

            Section 2.3 Payment of Amounts Drawn Under Letters of Credit;
Obligation of Reimbursement.

            The Borrower acknowledges that the Lender, as co-applicant, will be
liable to the Issuer for reimbursement of any and all draws under Letters of
Credit and for all other amounts required to be paid under the applicable L/C
Application. Accordingly, the Borrower agrees to pay to the Lender any and all
amounts required to be paid under the applicable L/C Application, when and as
required to be paid thereby, and the amounts designated below, when and as
designated:

            (a) The Borrower hereby agrees to pay the Lender on the day a draft
      is honored under any Letter of Credit a sum equal to all amounts drawn
      under such Letter of Credit plus any and all reasonable charges and
      expenses that the Issuer or the Lender may pay or incur relative to such
      draw and the applicable L/C Application, plus interest on all such
      amounts, charges and expenses as set forth below (the Borrower's
      obligation to pay all such amounts is herein referred to as the
      "Obligation of Reimbursement").

            (b) Whenever a draft is submitted under a Letter of Credit, the
      Lender shall make a Revolving Advance in the amount of the Obligation of
      Reimbursement and shall apply the proceeds of such Revolving Advance
      thereto. Such Revolving Advance shall be repayable in accordance with and
      be treated in all other respects as a Revolving Advance hereunder.

            (c) If a draft is submitted under a Letter of Credit when the
      Borrower is unable, because a Default Period then exists or for any other
      reason, to obtain a Revolving Advance to pay the Obligation of
      Reimbursement, the Borrower shall pay to the Lender on demand and in
      immediately available funds, the amount of the Obligation of Reimbursement
      together with interest, accrued from the date of the draft until payment
      in full at the Default Rate. Notwithstanding the Borrower's inability to
      obtain a Revolving Advance for any reason, the Lender is irrevocably
      authorized, in its sole discretion, to make a Revolving Advance in an
      amount sufficient to discharge the Obligation of Reimbursement and all
      accrued but unpaid interest thereon.

            (d) The Borrower's obligation to pay any Revolving Advance made
      under this Section 2.3, shall be evidenced by Revolving Note and shall
      bear interest as provided in Section 2.6.

            Section 2.4 Special Account. If the Credit Facility is terminated
for any reason whatsoever while any Letter of Credit is outstanding, the
Borrower shall thereupon pay the Lender in immediately available funds for
deposit in the Special Account an amount equal to the L/C Amount. The Special
Account shall be an interest bearing account maintained for the Lender by any


                                       11
<PAGE>


financial institution acceptable to the Lender. Any interest earned on amounts
deposited in the Special Account shall be credited to the Special Account.
Amounts on deposit in the Special Account may be applied by the Lender at any
time or from time to time to the Obligations in the Lender's sole discretion,
and shall not be subject to withdrawal by the Borrower so long as the Lender
maintains a security interest therein. The Lender agrees to transfer any balance
in the Special Account to the Borrower at such time as the Lender is required to
release its security interest in the Special Account under applicable law.

            Section 2.5 Obligations Absolute. The Borrower's obligations arising
under Section 2.3 shall be absolute, unconditional and irrevocable, and shall be
paid strictly in accordance with the terms of Section 2.3, under all
circumstances whatsoever, including (without limitation) the following
circumstances:

            (a) any lack of validity or enforceability of any Letter of Credit
      or any other agreement or instrument relating to any Letter of Credit
      (collectively the "Related Documents");

            (b) any amendment or waiver of or any consent to departure from all
      or any of the Related Documents;

            (c) the existence of any claim, setoff, defense or other right which
      the Borrower may have at any time, against any beneficiary or any
      transferee of any Letter of Credit (or any persons or entities for whom
      any such beneficiary or any such transferee may be acting), or other
      person or entity, whether in connection with this Agreement, the
      transactions contemplated herein or in the Related Documents or any
      unrelated transactions;

            (d) any statement or any other document presented under any Letter
      of Credit proving to be forged, fraudulent, invalid or insufficient in any
      respect or any statement therein being untrue or inaccurate in any respect
      whatsoever;

            (e) payment by or on behalf of the Issuer or the Lender under any
      Letter of Credit against presentation of a draft or certificate which does
      not strictly comply with the terms of such Letter of Credit; or

            (f) any other circumstance or happening whatsoever, whether or not
      similar to any of the foregoing.

            Section 2.6 Interest; Minimum Interest Charge; Default Interest;
Participations; Usury. Interest accruing on the Note shall be due and payable in
arrears on the first day of each month.

            (a) REVOLVING NOTE. Except as set forth in Sections 2.2(c) and
      2.2(f), the outstanding principal balance of the Revolving Note shall bear
      interest at the Floating Rate.


                                       12
<PAGE>


            (b) MINIMUM INTEREST CHARGE. Notwithstanding the interest payable
      pursuant to Section 2.2(a), the Borrower shall pay to the Lender interest
      of not less than the applicable amount shown below per year of this
      Agreement (the "Minimum Interest Charge") during the term of this
      Agreement, and the Borrower shall pay any deficiency between the Minimum
      Interest Charge and the amount of interest otherwise calculated under
      Sections 2.6(a) and 2.6(c) on the date and in the manner provided in
      Section 2.8:

            Period                                   Minimum Annual Interest
            ------                                   -----------------------

            Year One of Agreement                    $80,000
            Year Two of Agreement and thereafter     $95,000

            (c) DEFAULT INTEREST RATE. At any time during any Default Period, in
      the Lender's sole discretion and without waiving any of its other rights
      and remedies, the principal of the Advances outstanding from time to time
      shall bear interest at the Default Rate, effective for any periods
      designated by the Lender from time to time during that Default Period.

            (d) PARTICIPATIONS. If any Person shall acquire a participation in
      the Advances under this Agreement, the Borrower shall be obligated to the
      Lender to pay the full amount of all interest calculated under Section
      2.6(a), 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 than the Floating Rate, or
      otherwise elects to accept less than its prorata share of such fees,
      charges and other amounts due under this Agreement.

            (e) USURY. In any event no rate change shall be put into effect
      which would result in a rate greater than the highest rate permitted by
      law.

            Section 2.7 Fees.

            (a) ORIGINATION FEE. The Borrower hereby agrees to pay the Lender a
      fully earned and non-refundable origination fee of $20,000 due and payable
      upon the execution of this Agreement. The Lender acknowledges receipt of
      $8,500 toward payment of this fee and the fees, costs and expenses
      described in Sections 2.7(c) and 9.7.

            (b) UNUSED LINE FEE. For the purposes of this Section 2.7(b),
      "Unused Amount" means the Maximum Line reduced by outstanding Revolving
      Advances plus the L/C Amount. The Borrower agrees to pay to the Lender an
      unused line fee at the rate of one- quarter of one percent (.25%) per
      annum on the average daily Unused Amount from the date of this Agreement
      to and including the Termination Date, due and payable monthly in arrears
      on the first day of the month and on the Termination Date.

            (c) LETTER OF CREDIT FEES. The Borrower agrees to pay the Lender a
      fee with respect to each Letter of Credit, if any, accruing on a daily
      basis and computed at the annual


                                       13
<PAGE>


      rate of two percent (2%) of the aggregate amount that may then be drawn on
      all issued and outstanding Letters of Credit assuming compliance with all
      conditions for drawing thereunder (the "Aggregate Face Amount"), from and
      including the date of issuance of such Letter of Credit until such date as
      such Letter of Credit shall terminate by its terms or be returned to the
      Lender, due and payable monthly in arrears on the first day of each month
      and on the Termination Date; provided, however that during Default
      Periods, in the Lender's sole discretion and without waiving any of its
      other rights and remedies, such fee shall increase to four percent (4%) of
      the Aggregate Face Amount. The foregoing fee shall be in addition to any
      and all fees, commissions and charges of any Issuer of a Letter of Credit
      with respect to or in connection with such Letter of Credit.

            (d) LETTER OF CREDIT ADMINISTRATIVE FEES. The Borrower agrees to pay
      the Lender, on written demand, the administrative fees charged by the
      Issuer in connection with the honoring of drafts under any Letter of
      Credit, amendments thereto, transfers thereof and all other activity with
      respect to the Letters of Credit at the then-current rates published by
      the Issuer for such services rendered on behalf of customers of the Issuer
      generally.

            (e) AUDIT FEES. The Borrower hereby agrees to pay the Lender, on
      demand, audit fees in connection with any audits or inspections conducted
      by the Lender of any Collateral or the Borrower's operations or business
      at the rates established from time to time by the Lender as its audit fees
      (which fees are currently $62.50 per hour per auditor), together with all
      actual out-of-pocket costs and expenses incurred in conducting any such
      audit or inspection.

            Section 2.8 Computation of Interest and Fees; When Interest Due and
Payable. Interest accruing on the outstanding principal balance of the Advances
and fees hereunder outstanding from time to time shall be computed on the basis
of actual number of days elapsed in a year of 360 days. Interest shall be
payable in arrears on the first day of each month and on the Termination Date,
except that minimum interest pursuant to Section 2.6(b) shall be payable in
arrears annually on each anniversary date and on the Termination Date.

            Section 2.9 Capital Adequacy; Increased Costs and Reduced Return. If
any Related Lender determines at any time that its Return has been reduced as a
result of any Rule Change, such Related Lender may require the Borrower to pay
it the amount necessary to restore its Return to what it would have been had
there been no Rule Change. For purposes of this Section 2.5:

            (a) "Capital Adequacy Rule" means any law, rule, regulation,
      guideline, directive, requirement or request regarding capital adequacy,
      or the interpretation or administration thereof by any governmental or
      regulatory authority, central bank or comparable agency, whether or not
      having the force of law, that applies to any Related Lender. Such rules
      include rules requiring financial institutions to maintain total capital
      in amounts based upon percentages of outstanding loans, binding loan
      commitments and letters of credit.


                                       14
<PAGE>


            (b) "L/C Rule" means any law, rule, regulation, guideline,
      directive, requirement or request regarding letters of credit, or the
      interpretation or administration thereof by any governmental or regulatory
      authority, central bank or comparable agency, whether or not having the
      force of law, that applies to any Related Lender. Such rules include rules
      imposing taxes, duties or other similar charges, or mandating reserves,
      special deposits or similar requirements against assets of, deposits with
      or for the account of, or credit extended by any Related Lender, on
      letters of credit.

            (c) "Return", for any period, means the return as determined by such
      Related Lender on the Advances and Letters of Credit based upon its total
      capital requirements and a reasonable attribution formula that takes
      account of the Capital Adequacy Rules then in effect and costs of issuing
      or maintaining any Letter of Credit. Return may be calculated for each
      calendar quarter and for the shorter period between the end of a calendar
      quarter and the date of termination in whole of this Agreement.

            (d) "Rule Change" means any change in any Capital Adequacy Rule or
      L/C Rule occurring after the date of this Agreement, but the term does not
      include any changes in applicable requirements that at the Closing Date
      are scheduled to take place under the existing Capital Adequacy Rules or
      L/C Rules or any increases in the capital that any Related Lender is
      required to maintain to the extent that the increases are required due to
      a regulatory authority's assessment of the financial condition of such
      Related Lender.

            (e) "Related Lender" includes (but is not limited to) the Lender,
      the Issuer, any parent corporation of the Lender or the Issuer and any
      assignee of any interest of the Lender hereunder and any participant in
      the loans made hereunder.

Certificates of any Related Lender sent to the Borrower from time to time
claiming compensation under this Section 2.9, stating the reason therefor and
setting forth in reasonable detail the calculation of the additional amount or
amounts to be paid to the Related Lender hereunder to restore its Return shall
be conclusive absent manifest error. In determining such amounts, the Related
Lender may use any reasonable averaging and attribution methods.

            Section 2.10 Voluntary Prepayment; Reduction of the Maximum Line;
Termination of the Credit Facility by the Borrower; Automatic Renewal. Except as
otherwise provided herein, the Borrower may prepay the Advances in whole at any
time or from time to time in part. The Borrower may terminate the Credit
Facility or reduce the Maximum Line at any time if it (i) gives the Lender at
least 30 days' prior written notice and (ii) pays the Lender termination or line
reduction fees in accordance with Section 2.11. Any reduction in the Maximum
Line must be in an amount not less than $100,000 or an integral multiple
thereof. If the Borrower reduces the Maximum Line to zero, all Obligations shall
be immediately due and payable. Upon termination of the Credit Facility and
payment and performance of all Obligations, the Lender shall release or
terminate the Security Interest and the Security Documents to which the Borrower
is entitled by law. Unless terminated by the Lender at any time or by the
Borrower pursuant to Section 2.11, the Credit Facility shall


                                       15
<PAGE>


remain in effect until the Original Maturity Date and, thereafter, shall
automatically renew for successive one year periods (the Original Maturity Date
and each anniversary date thereof to which the Credit Facility has been
automatically renewed, is herein referred to as a "Maturity Date").

            Section 2.11 Termination and Line Reduction Fees; Waiver of
Termination an Line Reduction Fees.

            (a) TERMINATION AND LINE REDUCTION FEES. If the Credit Facility is
      terminated for any reason as of a date other than the Maturity Date, or
      the Borrower reduces the Maximum Line, the Borrower shall pay to the
      Lender a fee in an amount equal to a percentage of the Maximum Line (or
      the reduction, as the case may be) as follows: (A) two percent (2%) if the
      termination or reduction occurs on or before the first anniversary of the
      Funding Date and (B) one percent (1%) if the termination or reduction
      occurs after the first anniversary of the Funding Date.

            (b) WAIVER OF TERMINATION AND LINE REDUCTION FEES. The Borrower will
      not be required to pay the termination or line reduction fees otherwise
      due under this Section 2.11 if such termination or line reduction is made
      because of cash flow generated from the Borrower's operations or
      refinancing by an affiliate of the Lender.

            Section 2.12 Mandatory Prepayment. Without notice or demand, if the
sum of the outstanding principal balance of the Revolving Advances plus the L/C
Amount shall at any time exceed the Borrowing Base, the Borrower shall
immediately prepay the Revolving Advances to the extent necessary to eliminate
such excess; and (ii) if prepayment in full of the Revolving Advances is
insufficient to eliminate such excess, pay the Lender in immediately available
funds for deposit in the Special Account an amount equal to the remaining
excess. Any payment received by the Lender under this Section 2.12 or under
Section 2.10 may be applied to the Obligations, in such order and in such
amounts as the Lender, in its discretion, may from time to time determine.

            Section 2.13 Payment. All payments to the Lender shall be made in
immediately available funds and shall be applied to the Obligations upon receipt
by the Lender. The Lender may hold all payments not constituting immediately
available funds for two (2) days before applying them to the Obligations.
Notwithstanding anything in Section 2.1, the Borrower hereby authorizes the
Lender, in its discretion at any time or from time to time without the
Borrower's request and even if the conditions set forth in Section 4.2 would not
be satisfied, to make a Revolving Advance in an amount equal to the portion of
the Obligations from time to time due and payable.

            Section 2.14 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.


                                       16
<PAGE>


            Section 2.15 Use of Proceeds. The Borrower shall use the proceeds of
Advances for ordinary working capital purposes.

            Section 2.16 Liability Records. The Lender may maintain from time to
time, at its discretion, liability records as to the Obligations. All entries
made on any such record shall be presumed correct until the Borrower establishes
the contrary. Upon the Lender's demand, the Borrower will admit and certify in
writing the exact principal balance of the Obligations that the Borrower then
asserts to be outstanding. Any billing statement or accounting rendered by the
Lender shall be conclusive and fully binding on the Borrower unless the Borrower
gives the Lender specific written notice of exception within 30 days after
receipt.

                                   ARTICLE III

                      Security Interest; Occupancy; Setoff

            Section 3.1 Grant of Security Interest. The Borrower hereby pledges,
assigns and grants to the Lender a security interest (collectively referred to
as the "Security Interest") in the Collateral, as security for the payment and
performance of the Obligations.

            Section 3.2 Notification of Account Debtors and Other Obligors. The
Lender may at any time (whether or not a Default Period then exists) notify any
account debtor or other person obligated to pay the amount due that such right
to payment has been assigned or transferred to the Lender for security and shall
be paid directly to the Lender. The Borrower will join in giving such notice if
the Lender so requests. At any time after the Borrower or the Lender gives such
notice to an account debtor or other obligor, the Lender may, but need not, in
the Lender's name or in the 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 the Borrower's agent and attorney-in-fact,
notify the United States Postal Service to change the address for delivery of
the Borrower's mail to any address designated by the Lender, otherwise intercept
the Borrower's mail, and receive, open and dispose of the Borrower's mail,
applying all Collateral as permitted under this Agreement and holding all other
mail for the Borrower's account or forwarding such mail to the Borrower's last
known address.

            Section 3.3 Assignment of Insurance. As additional security for the
payment and performance of the Obligations, the 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 the 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 the Borrower hereby
directs the issuer of any such policy to pay all such monies directly to the
Lender. At any time, whether or not a Default Period then exists, the Lender may
(but need not), in the Lender's name or in the Borrower's


                                       17
<PAGE>


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) The Borrower hereby irrevocably grants to the Lender the right
      to take possession of the Premises at any time during a Default Period.

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

respect to any of the properties now owned or hereafter acquired by the
Borrower.

            Section 5.3 Legal Agreements. This Agreement constitutes and, upon

for its fiscal year ended June 30, 1999 and unaudited financial statements of

those statements fairly present the Borrower's financial condition on the dates
thereof and the results of its operations and cash flows for the periods then
ended and were prepared in accordance with generally accepted accounting

title to all Collateral described in the collateral reports provided to the
Lender and all other Collateral, properties and assets reflected in the latest
financial statements referred to in Section 5.5 and all proceeds thereof, free

            Section 6.4 Compliance with Laws.

            (a) The Borrower will (i) comply with the requirements of applicable
      laws and regulations, the non-compliance with which would materially and

      law, statute or ordinance.

            (b) Without limiting the foregoing undertakings, the Borrower
      specifically agrees that it will comply with all applicable Environmental
      Laws and obtain and comply with all permits, licenses and similar
      approvals required by any Environmental Laws, and will not generate, use,
      transport, treat, store or dispose of any Hazardous Substances in such a

or discharge, when due, (a) all taxes, assessments and governmental charges

      time replace or repair any worn, defective or broken parts; provided,
      however, that nothing in this Section 6.6 shall prevent the Borrower from
      discontinuing the operation and maintenance of any of its properties if
      such discontinuance is, in the Lender's judgment, desirable in the conduct
      of the Borrower's business and not disadvantageous in any material respect
      to the Lender.

maintain insurance with insurers believed by the 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

similar properties in the same general areas in which the Borrower operates.
Without limiting the generality of the foregoing, the 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

            (a) If, notwithstanding the instructions to debtors to make payments
      to the Lockbox, the Borrower receives any payments on Receivables, the
      Borrower shall deposit such payments into the Collateral Account. Until so
      deposited, the Borrower shall hold all such payments in trust for and as
      the property of the Lender and shall not commingle such payments with any
      of its other funds or property.

            (b) Amounts deposited in the Collateral Account shall not bear
      interest and shall not be subject to withdrawal by the Borrower, except
      after full payment and discharge of all Obligations.

            (c) All deposits in the Collateral Account shall constitute proceeds
      of Collateral and shall not constitute payment of the Obligations. The
      Lender from time to time at its discretion may, after allowing two (2)
      Banking Days, apply deposited funds in the Collateral


                                       30
<PAGE>


      Account to the payment of the Obligations, in any order or manner of
      application satisfactory to the Lender, by transferring such funds to the
      Lender's general account.

            (d) All items deposited in the Collateral Account shall be subject
      to final payment. If any such item is returned uncollected, the Borrower
      will immediately pay the Lender, or, for items deposited in the Collateral
      Account, the bank maintaining such account, the amount of that item, or
      such bank at its discretion may charge any uncollected item to the
      Borrower's commercial account or other account. The Borrower shall be
      liable as an endorser on all items deposited in the Collateral Account,
      whether or not in fact endorsed by the Borrower.

            Section 6.11 Performance by the Lender. If the 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 the Borrower written notice thereof
(or in the case of the agreements contained in Sections 6.5, 6.7 and 6.10,
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 Borrower (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 Borrower shall
thereupon 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
Floating Rate. To facilitate the Lender's performance or observance of such
covenants of the Borrower, the Borrower hereby irrevocably appoints the Lender,
or the Lender's delegate, acting alone, as the Borrower's attorney in fact
(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 the Borrower any and all instruments,
documents, assignments, security agreements, financing statements, applications
for insurance and other agreements and writings required to be obtained,

                                       38
<PAGE>


            (b) the Lender may, by notice to the Borrower, declare the
      Obligations to be forthwith due and payable, whereupon all Obligations
      shall become and be forthwith due and payable, without presentment, notice
      of dishonor, protest or further notice of any kind, all of which the
      Borrower hereby expressly waives;

            (c) the Lender may, without notice to the Borrower and without

      funds for deposit in the Special Account pursuant to Section 2.4 an amount

      conditions for drawing thereunder;

            (e) 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
      Borrower hereby expressly waives) and the right to sell, lease or
      otherwise dispose of any or all of the Collateral, and, in connection
      therewith, the Borrower 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;

            (f) the Lender may exercise and enforce its rights and remedies

                                  Miscellaneous

            Section 9.1 No Waiver; Cumulative Remedies. No failure or delay by
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 Borrower 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 the Borrower in any
case shall entitle the 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) personally delivered, (b) sent by first class United States mail,
(c) sent by overnight courier of national reputation, or (d) transmitted by
telecopy, in each case addressed or telecopied to the party to whom notice is

            Minnetonka, MN 55343

<PAGE>


or, as to each party, at such other address or telecopier number as may
hereafter be designated by such party in a written notice to the other party
complying as to delivery with the terms of this Section. All such notices,
requests, demands and other communications shall be deemed to have been given on
(a) the date received if personally delivered, (b) when deposited in the mail if
delivered by mail, (c) the date sent if sent by overnight courier, or (d) the
date of transmission if delivered by telecopy, except that notices or requests
to the Lender pursuant to any of the provisions of Article II shall not be
effective until received by the Lender.

            Section 9.4 Further Documents. The Borrower 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 Interest or the Lender's rights under the Loan
Documents (but any failure to request or assure that the Borrower executes,
delivers or endorses any such item shall not affect or impair the validity,
sufficiency or enforceability of the Loan Documents and the Security Interest,
regardless of whether any such item was or was not executed, delivered or
endorsed in a similar context or on a prior occasion).

            Section 9.5 Collateral. This Agreement does not contemplate a sale
of accounts, contract rights or chattel paper, and, as provided by law, the
Borrower is 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 Borrower 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 9.6 Costs and Expenses. The Borrower agrees to pay on demand
all costs and expenses, including (without limitation) reasonable attorneys'
fees, incurred by the Lender in connection with the Obligations, this Agreement,
the Loan Documents, any Letters of Credit, 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 Interest.

            Section 9.7 Indemnity. In addition to the payment of expenses
pursuant to Section 9.7, the Borrower agrees 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, attorneys and agents of
the foregoing (the "Indemnitees") from and against any of the following
(collectively, "Indemnified Liabilities"):


                                       41
<PAGE>


                  (i) any and all transfer taxes, documentary taxes, assessments
            or charges made by any governmental authority by reason of the
            execution and delivery of the Loan Documents or the making of the
            Advances;

                  (ii) any claims, loss or damage to which any Indemnitee may be
            subjected if any representation or warranty contained in Section
            5.12 proves to be incorrect in any respect or as a result of any
            violation of the covenant contained in Section 6.4(b); and

                  (iii) any and all other 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 the foregoing
            and any other 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 any such
            Indemnitee, in any manner related to or arising out of or in
            connection with the making of the Advances and the Loan Documents or
            the use or intended use of the proceeds of the Advances.

If any investigative, judicial or administrative proceeding arising from any of
the foregoing is brought against any Indemnitee, upon such Indemnitee's request,
the Borrower, or counsel designated by the Borrower 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 Borrower's sole costs 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 Borrower shall nevertheless make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. The Borrower's obligation
under this Section 9.7 shall survive the termination of this Agreement and the
discharge of the Borrower's other obligations hereunder.

      An Indemnitee seeking indemnification under this Section 9.7 will notify
the Borrower of any event requiring indemnification within a reasonable amount
of time following such Indemnitee's receipt of notice of commencement of any
action or proceeding, or such Indemnitee's obtaining knowledge of the occurrence
of any other event, giving rise to a claim for indemnification hereunder. The
Borrower will be entitled (but not obligated ) to assume the defense or
settlement of any such action or proceeding or to participate in any
negotiations to settle or otherwise resolve any claim using counsel of its
choice; provided that such counsel is reasonably satisfactory to such
Indemnitee. If the Borrower elects to assume the defense or settlement of any
such action or proceeding, such Indemnitee (and its counsel) may continue to
participate at its own expense in such action or proceeding.

            Section 9.8 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 Lender's participants, successors or
assigns.

            Section 9.9 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 9.10 Binding Effect; Assignment; Complete Agreement;
Exchanging Information. The Loan Documents shall be binding upon and inure to
the benefit of the Borrower and the Lender and their respective successors and
assigns, except that the Borrower shall not have the right to assign its rights
thereunder or any interest therein without the Lender's prior written consent.
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. Without
limiting the Lender's right to share information regarding the Borrower and its
Affiliates with the Lender's participants, accountants, lawyers and other
advisors, the Lender, Wells Fargo Corporation, and all direct and indirect
subsidiaries of Wells Fargo Corporation, may exchange any and all information
they may have in their possession regarding the Borrower and its Affiliates, and
the Borrower waives any right of confidentiality it may have with respect to
such exchange of such information.

            Section 9.11 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 9.12 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.

            Section 9.13 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 Minnesota. This
Agreement shall be governed by and construed in accordance with the substantive
laws (other than conflict laws) of the State of Minnesota. The parties hereto

judgment or in any other manner provided by law. THE PARTIES WAIVE ANY RIGHT TO
TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED ON OR PERTAINING TO THIS
AGREEMENT.

            Section 9.14 Confidentiality. The Lender agrees to exercise due care
to maintain the confidentiality of all information relating to the Borrower
which has been provided to the Lender, and neither the Lender nor any of its
affiliates shall use any such information for any purpose in any manner other
than pursuant to the terms contemplated by the Loan Documents, except to the
extent such information (a) was or becomes generally available to the public,
other than as result of a disclosure by the Lender, or (b) was or becomes
available on a nonconfidential basis from a source other than the Borrower,
provided that such source is not bound by a confidentiality agreement with the
Borrower that is known to the Lender; provided further, however, that the Lender
may disclose such information (i) at the request of or pursuant to any
requirement of any governmental authority to which the Lender is subject to or
in connection with the examination of the Lender by any such authority, (ii)
pursuant to a subpoena or other court process; (iii) when required to do so in
accordance with the provisions of any applicable law, (iv) to the Lender's
independent auditors and other professional advisors, and (v) to any person or
entity and in any proceeding necessary in the Lender's reasonable judgment to
protect the Lender's interest in connection with any claim or dispute involving
the Lender. The Borrower authorizes the Lender to disclose to any prospective
transferee such financial and other information in the Lender's possession,
provided that, prior to such disclosure, such prospective transferee agrees in
writing to be bound by the provisions of this Section 9.14.

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