NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION
AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
--------------------------------------------------------------------------------

1.    INTERIM FINANCIAL INFORMATION

      In the opinion of management, the accompanying unaudited consolidated
      financial statements contain all necessary adjustments, which are of a
      normal recurring nature, to present fairly the consolidated financial
      position of Northern Technologies International Corporation and Subsidiary
      (the Company) as of November 30, 2002 and the results of their operations
      and their cash flows for the three months ended November 30, 2002 and
      2001, in conformity with accounting principles generally accepted in the
      United States of America.

      These financial statements should be read in conjunction with the
      financial statements and related notes as of and for the year ended August
      31, 2002 contained in the Company's filing on Form 10-KSB dated November
      15, 2002 and with Management's Discussion and Analysis of Financial
      Condition and Results of Operations appearing on pages 7 through 12 of
      this quarterly report.

      Certain fiscal year 2002 amounts have been reclassified to conform to
      fiscal year 2003 presentations. These classifications had no effect on
      stockholders' equity, sales, or net income as previously reported.

2.    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

      In August 2001, the Financial Accounting Standards Board (FASB) issued
      Statement of Financial Accounting Standards (SFAS) No. 143, Accounting for
      Asset Retirement Obligations. SFAS No. 143 requires entities to record the
      fair value of a liability for an asset retirement obligation in the period
      in which it is incurred. When the liability is initially recorded, the
      entity capitalizes a cost by increasing the carrying amount of the related
      long-lived asset. Over time, the liability is accreted to its present
      value each period, and the capitalized cost is depreciated over the useful
      life of the related asset. Upon settlement of the liability, an entity
      either settles the obligation for its recorded amount or incurs a gain or
      loss upon settlement. SFAS No. 143 is effective for fiscal years beginning
      after June 15, 2002. The Company adopted SFAS No. 143 effective September
      1, 2002. SFAS No. 143 does not have a material impact on the financial
      position and results of operations.

      In September 2001, the FASB issued SFAS No. 144, Accounting for the
      Impairment or Disposal of Long-lived Assets. SFAS No. 144 replaces SFAS
      No. 121, Accounting for the Impairment of Long-Lived Assets and for
      Long-Lived Assets to Be Disposed Of. The FASB issued SFAS No. 144 to
      establish a single accounting model, based on the framework established in
      SFAS No. 121, as SFAS No. 121 did not address the accounting for a segment
      of a business accounted for as a discontinued operation under Accounting
      Principle Board Opinion No. 30, Reporting the Results of Operations -
      Reporting the Effects of Disposal of a Segment of a Business, and
      Extraordinary, Unusual and Infrequent Occurring Events and Transactions.
      SFAS No. 144 also resolves significant implementation issues related to
      SFAS No. 121. The provisions of SFAS No. 144 are effective for fiscal
      years beginning after December 15, 2001 and are to be applied
      prospectively. The Company adopted SFAS No. 144 effective September 1,
      2002 which had no impact on the financial position and results of
      operations.

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

Critical Accounting Policies

The consolidated financial statements include accounts of the Company and its
wholly owned subsidiary. All significant intercompany transactions have been
eliminated.

Sales Originating in North America - The Company considers sales originating in
North America to be all sales shipped/invoiced from the Company's facilities
located in Minnesota and Ohio. There are no sales from the international
corporate joint ventures included in the amount as the Company's investments in
international corporate joint ventures are accounted for using the equity
method.

Cash Equivalents - The Company considers investments with an original maturity
of three months or less to be cash equivalents.

Investments Available for Sale - The Company accounts for securities available
for sale in accordance with Statement of Financial Accounting Standards No. 115,
Accounting for Certain Investments in Debt and Equity Securities ("SFAS No.
115"). SFAS No. 115 requires that available-for-sale securities be carried at
fair value, with unrealized gains and losses reported as other comprehensive
income within shareholders' investment, net of applicable income taxes. Realized
gains and losses and decline in value deemed to be other-than-temporary on
available-for-sale securities are included in other income. Fair value of the
securities is based upon the quoted market price on the last business day of the
quarter or fiscal year. The cost basis for realized gains and losses on
available-for-sale securities is determined on a specific identification basis.
At November 30, 2002, the Company's securities available for sale consisted of
commercial paper, corporate debt, certificate's of deposit and discount notes
with a cost value and accrued interest income totaling $3,055,210 which
approximates fair value.

Inventories - Inventories are recorded at the lower of cost (first-in, first-out
basis) or market.


                                       7
<PAGE>

Property and Depreciation - Property and equipment are stated at cost.
Depreciation is computed using the straight-line method based on the estimated
service lives of the various assets as follows:

Buildings and improvements                                        5-20 years
Machinery and equipment                                           3-10 years

Investments in International Corporate Joint Ventures and German Corporation -
Investments in international corporate joint ventures and German corporation are
accounted for using the equity method. Intercompany profits on inventories held
by the international corporate joint ventures that were purchased from the
Company have been eliminated based on the Company's ownership percentage in each
international corporate joint venture.

Recoverability of Long-Lived Assets - The Company reviews its long-lived assets
whenever events or changes in circumstances indicate the carrying amount of the
assets may not be recoverable. The Company determines potential impairment by
comparing the carrying value of the assets with expected net cash flows expected
to be provided by operating activities of the business or related products.
Should the sum of the expected undiscounted future net cash flows be less than
the carrying value, the Company would determine whether an impairment loss
should be recognized. An impairment loss would be measured by comparing the
amount by which the carrying value exceeds the fair value of the asset. As of
November 30, 2002, the Company did not consider any of its assets impaired.

Income Taxes - The Company utilizes the liability method of accounting for
income taxes as set forth in Statement of Financial Accounting Standards (SFAS)
No. 109, Accounting for Income Taxes. SFAS No. 109 requires an asset and
liability approach to financial accounting and reporting for income taxes.
Deferred income tax assets and liabilities are computed annually for differences
between the financial statement and tax basis of assets and liabilities that
will result in taxable or deductible amounts in the future, based on enacted tax
laws and rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary to
reduce deferred tax assets to the amount expected to be realized. Income tax
expense is the tax payable or refundable for the period plus or minus the change
during the period in deferred tax assets and liabilities.

Foreign Currency Translation (Accumulated Other Comprehensive Loss) - The
functional currency of the international corporate joint ventures and the German
corporation is the applicable local currency. The translation of the applicable
foreign currencies into U.S. dollars is performed for balance sheet accounts
using current exchange rates in effect at the balance sheet date and for revenue
and expense accounts using an average monthly exchange rate. Translation gains
or losses are reported as an element of accumulated other comprehensive loss.

Revenue Recognition - In recognizing revenue, the Company applies the provisions
of the Securities & Exchange Commission Staff Accounting Bulletin 101, Revenue
Recognition. The Company recognizes revenue from the sale of its products when
persuasive evidence of an arrangement exists, the product has been delivered,
the fee is fixed and determinable and collection of the resulting receivable is
reasonably assured. A portion of the gross profit on products shipped to the
Company's international corporate joint ventures is deferred until such products
are sold by the international corporate joint ventures.

Shipping and Handling - The Company records all amounts billed to customers in a
sales transaction related to shipping and handling as sales. The Company records
costs related to shipping and handling in cost of goods sold.

Use of Estimates - The preparation of the financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.


RESULTS OF OPERATIONS

General - The Company conducts all foreign transactions based on the U.S.
dollar, except for its investments in foreign joint ventures and German
corporation. The exchange rate differential relating to investments in foreign
joint ventures and German corporation is accounted for under the requirements of
SFAS No. 52.

Sales Originating in North America - Net sales decreased by $61,167 or 3.0%
during the first quarter of 2003 from the first quarter of 2002. These changes
in sales are due to a decrease in demand for materials science based industrial
packaging products. This decrease in demand was due to the slow down in the
industrial sector we serve.

Cost of Sales - Cost of goods sold as a percentage of net sales were 46.3% and
45.1% for the first quarter of 2003 and 2002, respectively. Variations are due
primarily to the mix of product sales and changes in the price of resin.

Operating Expenses - As a percentage of net sales, total operating expenses were
57.6% in the first quarter of fiscal 2003 and 45.4% in the first quarter of
fiscal 2002.

Operating expense classification percentages of net sales were as follows:

Research, engineering, and
  technical support                   11                            9

Selling Expenses. The Company's selling expenses increased by $208,464 or 77.4%
to $477,740 during the first quarter of fiscal 2003 as compared to $269,276
during the same period in fiscal 2002. The increase in selling expenses during
the first quarter of fiscal 2003 was primarily related to increases in salary
and commission and travel related expenses for sales personnel, and increased
expenses related to trade shows. As a percentage of sales these costs increased
to 24.1% in the first quarter of fiscal 2003 from 13.2% in the first quarter of
fiscal 2002 due to the decreased level of net sales and the overall significant
increase in selling expenses in the first quarter of fiscal 2003.

General and Administrative Expenses. The Company's general and administrative
expenses decreased by $14,311 or 3.1% to $452,590 in the first quarter of fiscal
2003 from $466,901 in the first quarter of fiscal 2002. The decrease is
attributed to there being no expenses relating to NIC; the wholly owned
subsidiary that ceased operations in fiscal year 2002. Additionally, there was a
decrease in total salary expense and increases in legal fees and group insurance
expenses. As a percentage of sales, general and


                                       9
<PAGE>

administrative expenses decreased to 22.8% in the first quarter of fiscal 2003
from 22.9% in the first quarter of fiscal 2002.

Research, Engineering, and Technical Support Expenses. The Company's research,
engineering, and technical support expenses increased by $20,614 or 10.8% to
$210,710 in the first quarter of fiscal 2003 from $190,096 in the first quarter
of fiscal 2002. The increase is attributed to an increase in salary expense
related to hiring additional people in technical support and higher group
insurance expense. As a result of the Company's international research and
development activities, certain proprietary rights to new technology have been
added to the Company. As a percentage of sales, research, engineering and
technical support expenses increased to 10.6% in the first quarter of fiscal
2003 from 9.3% in the first quarter of fiscal 2002 due to the decreased level of
net sales and the slight increase in spending.

International Corporate Joint Ventures, German Corporation and European Holding
Company - Net earnings from international corporate joint ventures, German
corporation and European holding company were $305,627 for the three months
ended November 30, 2002, compared to $458,553 for the three months ended
November 30, 2001. This decrease is due to increased joint venture expenses,
which more than offset the increases in equity in income and fees for technical
support and other services.

Income Taxes - Income tax benefit (expense) for the three months ended November
30, 2002 and 2001 was calculated based on management's estimate of the Company's
annual effective income tax rate. The Company's annual effective income tax rate
for fiscal 2003 is lower than the statutory rate primarily due to the Company's
equity in income of international corporate joint ventures being recognized
based on after-tax earnings of these entities. To the extent joint ventures'
undistributed earnings are distributed to the Company, it is not expected to
result in any material additional income tax liability after the application of
foreign tax credits.

LIQUIDITY AND CAPITAL RESOURCES

At November 30, 2002, the Company's working capital was $5,605,940, including
$243,721 in cash and cash equivalents and $3,055,210 in investments available
for sale, compared to a working capital of $6,276,934, including $230,274 in
cash and cash equivalents and $4,008,417 in investments available for sale at
August 31, 2002.

Net cash provided from operations for the past 12 months has been sufficient to
meet liquidity requirements, capital expenditures, research and development
cost, and expansion of operations of the Company's international joint ventures.
Cash flows used in operations for the three months ended November 30, 2002 and
2001 was ($855,388) and ($26,248), respectively. The net cash used in operations
for the three months ended November 30, 2002 resulted principally from cash
provided from net income, depreciation and trade receivables more than offset by
the noncash equity income of foreign investees, and uses of cash for increases
in operating assets and reductions of operating liabilities. During the quarter,
the Company made a $445,469 deposit relating to a legal case involving potential
patent infringement against a competitor in Europe. The Company expects that the
amount will be fully recoverable at the conclusion of the prosecution of the
competitor. The net cash used in operations for the three months ended November
30, 2001 resulted principally from net income and depreciation, offset by equity
income of international corporate joint ventures and European holding company,
and increases in prepaid expenses and other.

Net cash provided by investing activities for the three months ended November
30, 2002 was $895,495, which resulted from the sales of investments and a
partial return of the Company's original investment in European holding company
partially offset by investments in international joint ventures, increase in


                                       10
<PAGE>

other assets and additions to property and equipment. Net cash provided by
investing activities for the three months ended November 30, 2001 was $23,776,
which resulted from a partial return of the Company's original investment in
European holding company partially offset by an increase in other assets and
additions to property and equipment.

Net cash used in financing activities for the three months ended November 30,
2002 was $26,660, which resulted from the repurchase of common stock. Net cash
used in financing activities for the three months ended November 30, 2001 was
$100,000, which resulted from the repurchase of common stock.

The Company expects to meet future liquidity requirements by utilizing its
existing cash and cash equivalents and investments available for sale combined
with cash flows of future operating earnings and distributions of earnings and
technical assistance fees from the international corporate joint venture
investments.

The Company has no long-term debt and no material capital lease commitments at
November 30, 2002; however, the Company's subsidiary has entered into a 15-year
lease agreement for 16,826 square feet of office, manufacturing, laboratory, and
warehouse space requiring monthly payments of $16,434, which can be adjusted
annually according to the annual consumer price index through November 2014.

The Company has no postretirement benefit plan and does not anticipate
establishing any postretirement benefit program.

Recently Issued Accounting Pronouncements

In August 2001, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standard (SFAS) No. 143, Accounting for Asset Retirement
Obligations. SFAS No. 143 requires entities to record the fair value of a
liability for an asset retirement obligation in the period in which it is
incurred. When the liability is initially recorded, the entity capitalizes a
cost by increasing the carrying amount of the related long-lived asset. Over
time, the liability is accreted to its present value each period, and the
capitalized cost is depreciated over the useful life of the related asset. Upon
settlement of the liability, an entity either settles the obligation for its
recorded amount or incurs a gain or loss upon settlement. SFAS No. 143 is
effective for fiscal years beginning after June 15, 2002. The Company adopted
SFAS No. 143 effective September 1, 2002. SFAS No. 143 does not have an impact
on the financial position and results of operations.

In September 2001, the FASB issued SFAS No. 144, Accounting for the Impairment
or Disposal of Long-lived Assets. SFAS No. 144 replaces SFAS No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. The FASB issued SFAS No. 144 to establish a single accounting model, based
on the framework established in SFAS No. 121, as SFAS No. 121 did not address
the accounting for a segment of a business accounted for as a discontinued
operation under Accounting Principle Board Opinion No. 30, Reporting the Results
of Operations - Reporting the Effects of Disposal of a Segment of a Business,
and Extraordinary, Unusual and Infrequent Occurring Events and Transactions.
SFAS No. 144 also resolves significant implementation issues related to SFAS No.
121. The provisions of SFAS No. 144 are effective for fiscal years beginning
after December 15, 2001 and are to be applied prospectively. The Company adopted
SFAS No. 144 effective September 1, 2002, which had no impact on the financial
position and results of operations.

Disclosure of the Control Environment

Within the 90-day period prior to the filing date of this report, management
performed an evaluation, of the effectiveness of the design and operation of our
disclosure controls and procedures as defined in Exchange Act Rules 13a-14(C)
and 15d-14(C). We performed this evaluation under the supervision of, and with
participation from, our Chairman of the Board & Co-Chief Executive Officer,
President & Co-Chief Executive Officer, and Chief Financial Officer. Based upon
that evaluation we, as well as our Chairman of the Board & Co-Chief Executive
Officer, President & Co-Chief Executive Officer, and Chief Financial Officer,
concluded that our disclosure controls and procedures were effective. There have
been no significant changes in our internal controls or in other factors that
could significantly affect internal controls subsequent to the date we carried
out this evaluation, and therefore we believe that our disclosure controls and
procedures remain effective. We intend to periodically evaluate our disclosure
controls and procedures as required by the Exchange Act Rules.
