ITEM 1.  BUSINESS.

(a)      BUSINESS DEVELOPMENT.

         Northern Instruments, Inc., a predecessor to Northern Technologies
International Corporation, was incorporated in the State of Minnesota on August
4, 1970. In 1976, Northern Instruments, Inc. changed its name to Northern
Instruments Corporation. In 1978, Northern Instruments Corporation, a Minnesota
corporation, was merged with and into Northern Instruments Corporation, a
newly-formed Delaware corporation. In 1993, Northern Technologies International
Corporation, a wholly owned subsidiary, was merged into Northern Instruments
Corporation. As a result of such merger, Northern Instruments Corporation
changed its name to Northern Technologies International Corporation, hereafter
referred to as the "Company" or "NTIC."

(b)      BUSINESS OF THE COMPANY.

GENERAL

         The Company is a developer, manufacturer and marketer of proprietary
corrosion inhibiting products and electronic sensing instruments. The Company's
dry corrosion inhibiting products, marketed under the name ZERUST(TM), are
utilized in protective packaging serving a wide variety of companies in
industries such as transportation, nuclear and fossil fuel power generation,
electronics, aerospace, on-and off-road automotive equipment, agriculture and
metal processing. The ZERUST product line accounted for approximately 98% of the
Company's sales during its fiscal year ended August 31, 1997.

         The Company's electronic sensing instruments include portable oil
quality analyzers for on-site evaluation of oils and fluids, instruments that
provide for on- and off-line measurement of fiber denier and critical tubing
measurements and measurement devices for slow moving materials and moisture
testing which utilize a microwave technology.

JOINT VENTURES, FOREIGN TRADING COMPANY AND EUROPEAN HOLDING COMPANY

         The Company participates in an expanding number of international joint
venture arrangements that manufacture, market and distribute corrosion
inhibiting products. The Company manufactures and supplies the proprietary
ingredient that makes the finished product functional, but the actual
manufacturing of the finished product takes place in the foreign country.
Manufacturing the product in the foreign country lowers shipping costs and
improves on-time delivery to foreign customers. The joint venture arrangements
allow the Company to successfully market and sell its products in foreign
countries through the marketing efforts of joint venture partners without having
to develop its own international sales force. The Company's joint venture
partners are knowledgeable in the applicable environmental, tax and other laws
of the foreign


<PAGE>


country, as well as the local customs and business practices, and have a vested
interest in making the joint venture a success.

         All of the Company's joint ventures are owned 50% by the Company,
except where the Company has allowed Taiyo Petroleum Gas Co. Ltd. to purchase
from the joint venture a portion of the ownership that the Company would
otherwise have purchased. For instance, the Company owns 40%, 40% and 25% and
Taiyo Petroleum Gas Co. Ltd. owns 10%, 10% and 25% of the joint ventures in
Taiwan, Singapore and South Korea, respectively. In 1997, the Company organized
NTI Asean LLC, a Nevada limited liability company, as the Company's vehicle for
its joint venture investments in the Asia-Pacific market. The Company maintains
a 50% interest in NTI Asean LLC with the remaining 50% ownership interest owned
by Taiyo Petroleum Gas Co. Ltd. The Company has established the following
corporate joint ventures:

                                           Date of
              Country                     Investment

              Taiwan                         1990
              France                         1990
              Germany                        1991
              Sweden                         1991
              Singapore                      1991
              Brazil                         1993
              Russia                         1994
              South Korea                    1994
              Finland                        1995
              Italy                          1996
              United Kingdom                 1997
              Czech-Republic                 1997

         In addition to the Company's investments in the corporate joint
ventures listed above, the Company created joint venture entities during fiscal
1997 in Thailand and Indonesia (to be funded through NTI Asean LLC) and Poland.
The Company anticipates that the funding of these joint venture investments will
occur in fiscal 1998. Additionally, during fiscal 1997, the Company purchased a
50% ownership interest in a European holding company; however, to date, this
entity has been inactive.

         The Company also owns a 50% ownership interest in a foreign trading
company. The trading company sells merchandise directly and serves as an
intermediary in the arrangement of sales of goods on which it receives
commissions. The trading company's transactions include sales of ZERUST products
produced by one of the Company's international corporate joint ventures.

         While the Company is not aware of any specific potential risk beyond
its initial investment and undistributed earnings of the joint ventures, there
can be no assurance that the Company will not be subject to lawsuits based on
product liability claims or other claims arising out of the activities of the
joint ventures. To protect against such an occurrence, the Company maintains
liability insurance specifically applicable to its ownership positions in the
international joint venture arrangements in excess of any insurance the joint
ventures maintain.

PRODUCTS

         The Company operates in two industry segments: corrosion inhibiting
packaging products and electronic sensing instruments. Corrosion inhibiting
packaging products accounted for approximately 98% of the Company's sales in
fiscal 1997.

         CORROSION INHIBITING PACKAGING PRODUCTS. Corrosion affects products and
components in the manufacturing industry. It encompasses the corrosion of
ferrous (iron and steel) metals as well as the deterioration of nonferrous
(aluminum, copper, brass, etc.) metals. In combating corrosion, the traditional
approach has been to apply oils and greases to protect metal parts. This
approach may require specialized application equipment. In addition, the oils
and greases may pose unacceptable health and fire hazards and may collect and
trap dirt and debris that, in some cases, may actually initiate corrosion.
Should the removal of the oils and greases be required, solvents and specialized
safety equipment may be necessary that typically introduce additional health and
hazardous waste disposal problems.

         ZERUST volatile corrosion inhibiting ("VCI") products contain
proprietary chemical systems that emit a nontoxic vapor that is diffused
throughout an enclosure. Electron scanning instrumentation shows that the
VCI-rich atmosphere causes VCI molecules to condense in a microscopic layer on
all surfaces they can reach. The inhibiting layer is maintained so long as the
product remains in the ZERUST package. Electron scanning further shows that once
the contents are removed from the ZERUST package, the VCI layer revolatizes from
the contents' surfaces within two hours, leaving a clean, dry and corrosion-free
product. The protective mechanism enables parts to arrive ready for immediate
use. By eliminating costly greasing and degreasing processes, ZERUST VCI
technology offers significant savings in labor, material and space compared to
other methods of corrosion prevention.

         In 1980, the Company developed a means of combining ZERUST VCI systems
with polyethylene and polypropylene resins. Subsequently, a line of flexible
packaging products in the form of low and high density polyethylene bags and
shroud film, stretch, shrink, skin and bubble cushioning film, woven scrim and
foam sheeting was introduced to United States industry. This offered packaging
engineers the opportunity to ship and store ferrous, nonferrous and mixed
multi-metal products in a clean, dry and corrosion-free condition, with an
attendant overall savings in total packaging cost.

         The Company subsequently expanded the ZERUST product line to include a
range of rigid plastic products in the form of profile and corrugated board,
thermoformed dunnage trays and bins, injection and blow molded products and flat
netting. The Company also has additives in liquid form for VCI enhancement of
corrugated cardboard, solid fibre and chipboard packaging materials.

         ELECTRONIC SENSING INSTRUMENTS. The Company's electronic sensing
instruments accounted for approximately 2% of the Company's sales in fiscal
1997. The Company's electronic sensing instruments include oil quality
analyzers, fiber monitors and testers and a tubing monitor. The Company's
electronic sensing instruments are based on the measurement of the change in
dielectric properties of different liquids and fibers by means of capacitance
sensors. The instrument product line also includes measurement devices for slow
moving materials and moisture testing which utilize a microwave technology. The
Company does not expect that its electronic sensing instruments will increase as
a percentage of sales in fiscal 1998.


<PAGE>


MANUFACTURING

         The Company produces certain proprietary corrosion inhibiting products
and electronic sensing instruments at its facility in Lino Lakes, Minnesota. The
corrosion inhibiting additives are produced by selected contractors based upon
the Company's proprietary formulation. The Company's inhibiting final products
include flexible packaging and other products that are produced to customer
specification by selected contractors who are supplied with the necessary
corrosion inhibiting additives by the Company.

SALES AND MARKETING

         The Company markets its products principally in the United States to
industrial users by a direct sales force and through a network of distributors
and sales representatives. The Company's technical service representatives work
directly with the end users of the Company's products to respond to their
technical requirements. The Company has also entered into joint venture
arrangements with foreign entities pursuant to which the Company sells certain
corrosion inhibiting formulations to foreign entities, who then manufacture and
market finished products. The Company receives fees for providing technical and
other support to the joint ventures in accordance with the terms of the joint
venture arrangements.

COMPETITION

         The Company is aware of competing organizations that manufacture and
market corrosion inhibiting products which are similar to the Company's ZERUST
products. The Company evaluates these products on an ongoing basis and is
satisfied that none of the products in the market at this time are superior to
the Company's products. In addition, corrosion inhibiting paper products are
marketed by competitors as an alternative to the Company's film products. As the
Company's film serves a dual role of moisture barrier as well as a dispenser of
corrosion inhibitors, it avoids a shortcoming of the paper inhibiting products
whose inhibitors are adversely affected and can leach out when heavy moisture is
encountered.

         The Company is aware of competitors in the Lubri-Sensor oil quality
analyzer area; however, the Company does not have any knowledge as to the
business effectiveness of such competitors and believes that the Company's
products are competitive with all other products currently on the market. In the
Foodoil Sensor oil quality analyzer area, the Company is aware of a competitor
who does not provide an analysis instrument but instead provides a paper test
strip. Although the Company believes that its product offers significant
advantages over paper test strips, the Company believes that sales of the
Foodoil Sensor are related to price sensitivity rather than differences in
product capabilities.

         Some of the Company's competitors, in both the corrosion inhibiting
area and the electronic instrument area, are established companies that may have
financial and other resources greater than those of the Company. Additionally,
some of these companies may have achieved significant market recognition. The
Company competes with such companies by providing high quality products and by
attempting to provide the highest level of customer service, including delivery
of its products on a timely basis at a competitive price.

SIGNIFICANT CUSTOMERS

         One customer accounted for approximately 14% of net sales for the
fiscal year ended August 31, 1997. No customer of the Company represented 10% or
more of the Company's net sales for the fiscal years ended August 31, 1996 and
1995.


<PAGE>


RESEARCH AND DEVELOPMENT

         Research and development expenditures, including engineering and
technical support, were $432,943, $370,045 and $353,887 in fiscal 1997, 1996 and
1995, respectively. The Company's research and development activities are
conducted at its Minnesota headquarters. The Company's research and development
activities are directed at the improvement of existing products, new product
development and quality assurance through testing of the Company's contract
manufactured corrosion inhibiting products.

         In 1997, a corrosion testing laboratory was established in Germany
under the sponsorship of Excor, the Company's corporate joint venture. This
laboratory works in conjunction with the domestic research and development
operation on testing directed at the improvement of existing products and new
product development.

PATENTS AND TRADEMARKS

         The Company currently owns one United States patent, which will expire
in 2000, relating to its corrosion inhibiting products. Although the Company has
sought patent protection for its technology and products, it does not believe
such protection is critical to its commercial success. The Company is committed
to the timely and continual upgrading of its product line and the introduction
of new products, developed in-house or via exclusive technology licenses. The
Company believes that trade secrets and proprietary (albeit unpatented) know-how
are at least as important as patent protection in establishing and maintaining a
competitive advantage. The Company also has several trademarks in the United
States and certain foreign countries. The Company's trademarks have a life,
subject to periodic maintenance, of 10 to 20 years, which may be extended.

BACKLOG

         The Company did not have a significant order backlog as of August 31,
1997. Customers generally place orders on an "as needed" basis and expect
delivery within a relatively short period of time.

WORKING CAPITAL AND AVAILABILITY OF MATERIALS

         The Company does not carry excess quantities of raw materials or
purchased parts because of widespread availability from various suppliers. The
Company has sufficient working capital to meet all obligations when due.

EMPLOYEES

         As of August 31, 1997, the Company had 25 full-time employees,
including five engaged in administration, eight in sales and marketing, four in
research and development and eight in operations. There are no unions
representing the Company's employees and the Company believes that its relations
with employees are good. There are no pending or threatened labor or employment
disputes or work interruptions.

CERTAIN IMPORTANT FACTORS

           In addition to the factors identified above, there are several
important factors that could cause the Company's actual results to differ
materially from those anticipated by the Company or which are reflected in any
forward-looking statements of the Company. These factors, and their impact on
the success of the Company's operations and its ability to achieve its goals,
include the following:

         (1) the ability of the Company's investments in existing and future
joint ventures to generate a positive rate of return and demonstrate a pattern
of growth consistent with current performance;

         (2) the Company's ability to continue to enter into international
markets in a timely fashion; and

         (3) the Company's ability to maintain gross margins at a level
consistent with current operating performance.

ITEM 2.   DESCRIPTION OF PROPERTY.

         The Company's office, production facilities and research and
development operations are located at 6680 North Highway 49, Lino Lakes,
Minnesota 55014. The Company owns approximately 3.5 acres at this site and three
buildings thereon. The main building, consisting of approximately 15,300 square
feet, is used for office, production, research and development and shipping and
receiving. A second building of approximately 7,200 square feet and a third
building of approximately 4,800 square feet are used for warehouse space. In
1995, the Company acquired an approximately 10 acre parcel of land located in
Forest Lake, Minnesota, approximately six miles from the Company's offices. The
Company built a warehouse on this parcel of approximately 18,000 square feet
that was completed in November 1996. The parcel of land on which this new
warehouse is located is of sufficient size should the Company choose to relocate
its entire facility to the new location, although the Company has no current
plans to do so.

ITEM 3.   LEGAL PROCEEDINGS.

         There are no material pending or threatened legal, governmental,
administrative or other proceedings to which the Company is a party or of which
any of its property is subject.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         No matter was submitted to a vote of security holders during the fourth

Company during the fiscal year ended August 31, 1997 which were not registered
under the Securities Act of 1933, as amended (the "Securities Act"):

         1. On November 15, 1996, the Company issued 3,000 shares of Common
Stock to six employees for services provided in fiscal 1996.

         2. In November 1996, the Company issued 8,000 shares of Common Stock to
two individuals upon the exercise of certain stock options at an exercise price
of $3.00 per share and 833 shares of Common Stock to one individual upon the
exercise of a stock option at an exercise price of $3.125 per share.

         3. In December 1996, the Company issued 200 shares of Common Stock to
one individual upon the exercise of a stock option at an exercise price of
$3.125 per share.


<PAGE>


         4. In July 1997, the Company issued 200 shares of Common Stock to one
individual upon the exercise of a stock option at an exercise price of $3.125
per share.

         All of the above sales were made in reliance on Section 4(2) of the
Securities Act as transactions by an issuer not involving any public offering.
In all such transactions, the recipients of securities represented their
intentions to acquire the securities for investment only and not with a view to
or for sale in connection with any distribution thereof and appropriate legends
were affixed to the securities issued in such transactions. All recipients had
adequate access, through their relationships with the Company, to information
about the Company.


ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

RESULTS OF OPERATIONS

FISCAL 1997 COMPARED TO FISCAL 1996

         NET SALES AND GROSS PROFIT. The Company's net sales of $8,729,318 in
fiscal 1997 increased by $1,860,134, or 27.1% from net sales of $6,869,184 in
fiscal 1996. The increase in net sales is primarily due to an increase in the
volume of corrosion inhibiting products sold to new and existing customers.
Fiscal 1997 sales to an existing customer increased significantly over fiscal
1996 and represents approximately 14% of total net sales in fiscal 1997. The
cost of sales increased as a percentage of sales to 47.4% in fiscal 1997 from
45.2% in fiscal 1996. The variation in the cost of sales percentage reflects
changes in product mix. The Company anticipates that its annual cost of sales
percentage for fiscal 1998 will not vary significantly under its current pricing
structure.

         SELLING EXPENSES. The Company's selling expenses increased by $257,630
or 30.9%, to $1,092,280 in fiscal 1997 from $834,650 in fiscal 1996. As a
percentage of sales these costs increased to 12.5% in fiscal 1997 from 12.2% in
fiscal 1996. The increase in fiscal 1997 selling expenses was primarily related
to increases in distributor commissions, salaries, travel and various
promotional expenses.

         GENERAL ADMINISTRATIVE EXPENSES. The Company's general and
administrative expenses increased by $491,983 or 35.3% to $1,886,016 in fiscal
1997 from $1,394,033 in fiscal 1996. As a percentage of sales these costs
increased to 21.6% in fiscal 1997 from 20.3% in fiscal 1996. The increase in
fiscal 1997 general and administrative expenses was primarily due to increases
in salaries and related expenses, various professional fees, insurance, legal
and real estate and other expenses associated with the Company's expanded
warehouse facility completed in November 1996.

         RESEARCH, ENGINEERING AND TECHNICAL SUPPORT EXPENSES. The Company's
research, engineering and technical support expenses increased by $62,898 or
17.0% to $432,943 in fiscal 1997 from $370,045 in fiscal 1996. As a percentage
of sales these costs decreased to 5.0% in fiscal 1997 from 5.4% in fiscal 1996.
The increase in fiscal 1997 research, engineering and technical support expenses
was primarily due to increases in salaries and travel. The Company anticipates
that its fiscal 1998 research, engineering and technical support expenses will
approximate expenses incurred in fiscal 1997.

         JOINT VENTURES. The Company continues its business program of
establishing joint venture arrangements in international markets. The Company
manufactures and supplies patented and proprietary ingredients which make the
finished products functional and enable manufacturing of the 


<PAGE>


finished products to take place in the foreign countries. The joint ventures
market the finished products and the joint ventures' profit is shared by the
respective joint venture shareholders in accordance with share ownership. The
Company also has an investment in a foreign company that operates as a trading
company. The Company's investments in corporate joint ventures and the foreign
trading company are accounted for using the equity method and resulted in income
to the Company of $712,244 and $488,969 for fiscal 1997 and fiscal 1996,
respectively. In addition, the Company received fees for technical and other
support to the joint ventures based on the revenues of the individual joint
ventures. The Company recognized fees for such assistance of $2,213,228 and
$1,659,792 for fiscal 1997 and fiscal 1996, respectively. The increase in equity
income in corporate joint ventures and the foreign trading company and fees for
technical and other support to corporate joint ventures was primarily due to the
joint ventures' increasing revenues and profitability as they progress. Sales of
the corporate joint ventures in fiscal 1997 increased by $4,701,791 or 33.1% to
$18,909,466. Net income of the corporate joint ventures in fiscal 1997 of
$1,489,856 represents a 27.5% increase over fiscal 1996. The Company anticipates
that in the future it will consider entering into joint ventures in other
foreign countries. The Company recognized expenses related to corporate joint
ventures of $457,263 and $346,677 in fiscal 1997 and fiscal 1996, respectively.
The expenses consisted primarily of legal fees regarding the development of new
joint ventures and travel, meetings and technical services regarding existing
joint ventures. The Company anticipates that expenses relating to corporate
joint ventures will continue to increase in the future due to the development of
new corporate joint ventures and the Company providing ongoing technical and
other support to existing joint ventures.

         INCOME TAXES. The Company's effective income tax rates were 31.5% and
34.3% for fiscal 1997 and fiscal 1996, respectively. The effective income tax
rate was lower than the statutory rate primarily due to equity in income of
corporate joint ventures being recognized on an after tax basis for these
entities. To the extent the joint ventures' undistributed earnings were
distributed to the Company during fiscal 1997 and fiscal 1996, it did not result
in material additional income tax liability after the application of foreign tax
credits.

FISCAL 1996 COMPARED TO FISCAL 1995

         NET SALES AND GROSS PROFIT. The Company's sales increased by $655,052,
or 10.5%, to $6,869,184 in fiscal 1996 from $6,214,132 in fiscal 1995. The
increase in sales is primarily due to an increase in the volume level of
shipments of corrosion inhibiting products. The cost of sales decreased as a
percentage of sales to 45.2% in fiscal 1996 from 47.4% in fiscal 1995. The
variation in the cost of sales percentage was primarily due to product mix.

         SELLING EXPENSES. The Company's selling expenses increased by $58,198,
or 7.5%, to $834,650 in fiscal 1996 from $776,452 in fiscal 1995. As a
percentage of sales these costs decreased to 12.2% from 12.5% for fiscal 1996
compared to fiscal 1995. The increase in fiscal 1996 selling expenses was
primarily due to an increase in sales salaries and related expenses and travel
expense.

         GENERAL AND ADMINISTRATIVE EXPENSES. The Company's general and
administrative expenses increased by $417,302, or 42.7%, to $1,394,033 in fiscal
1996 from $976,731 in fiscal 1995. As a percentage of sales these costs
increased to 20.3% from 15.7% for fiscal 1996 compared to fiscal 1995. The
increase in fiscal 1996 general and administrative expenses was primarily due to
increases in salaries and related expenses, various professional fees, meeting
expenses and waste disposal expense.

         RESEARCH, ENGINEERING AND TECHNICAL SUPPORT EXPENSES. The Company's
research, engineering and technical support expenses increased by $16,158 or
4.6% to $370,045 in fiscal 1996 from $353,887 in fiscal 1995. As a percentage of
sales these costs decreased to 5.4% in fiscal 1996 from 5.7% in fiscal 1995. The
increase in fiscal 1996 research, engineering and technical support expenses was
primarily due to increases in salaries.

         JOINT VENTURES. The Company's investments in corporate joint ventures
and the foreign trading company are accounted for using the equity method and
resulted in income to the Company of $488,969 and $428,639 for fiscal 1996 and
fiscal 1995, respectively. In addition, the Company received fees for technical
and other support to the joint ventures based on the revenues of the individual
joint ventures. The Company recognized fees for such assistance of $1,659,792
and $1,313,522 for fiscal 1996 and fiscal 1995, respectively. The increase in
equity income in corporate joint ventures and the foreign trading company and
fees for technical and other support to corporate joint ventures was primarily
due to the joint ventures' increasing revenues and profitability as they
progress. The Company recognized expenses related to corporate joint ventures of
$346,677 and $340,009 in fiscal 1996 and fiscal 1995, respectively. The expenses
consisted primarily of legal fees regarding the development of new joint
ventures and travel and technical services regarding existing joint ventures.

         INCOME TAXES. The Company's effective income tax rates were 34.3% and
30.9% for fiscal 1996 and fiscal 1995, respectively. The effective income tax
rate was lower than the statutory rate primarily due to equity in income of
corporate joint ventures being recognized on an after tax basis for these
entities. To the extent the joint ventures' undistributed earnings were
distributed to the Company during fiscal 1996 and fiscal 1995, it did not result
in material additional income tax liability after the application of foreign tax
credits.

LIQUIDITY AND CAPITAL RESOURCES

         At August 31, 1997, the Company's working capital was $5,826,590,
including $3,945,567 in cash and cash equivalents, with a current ratio of
7.1:1. At August 31, 1996, the Company's working capital was $5,284,403,
including $3,707,520 in cash and cash equivalents, with a current ratio of

lease commitments.

         In late 1995, the Company purchased an approximately 10 acre parcel of
land and began constructing an off-site warehouse on the site in March 1996. The
land, site development and construction of the warehouse was completed in
November 1996 and cost approximately $700,000 and was funded with existing cash
and cash equivalents.

         In fiscal 1997, the Company repurchased 9,000 shares of its Common
Stock in various open market transactions at prices ranging from $4.92 per share
to $7.13 per share. During fiscal 1997, holders of stock options exercise their
right to purchase 9,233 shares of Common Stock ranging from $3.00 to $3.13 per
share. In fiscal 1996, the Company repurchased 61,165 shares of its Common Stock
in various open market transactions at prices ranging from $4.88 per share to
$5.25 per share. During fiscal 1996, holders of stock options exercised their
rights to purchase 13,167 shares of Common Stock at prices ranging from $3.00 to

         On April 25, 1994, Inter Alia Holding Company ("Inter Alia") exercised
a warrant to purchase 233,000 shares of Common Stock at an exercise price of
$2.50 per share, for an aggregate exercise price of $582,500. In connection with
such exercise, Inter Alia paid $4,660 in cash and issued a promissory note to
the Company in the amount of $577,840, which had an interest rate of 7.25% per
annum and was due 


<PAGE>


December 31, 1995. The note was collateralized by marketable equity securities.
This note was paid in full in fiscal 1996.

         Over the past three fiscal years, cash flow from operations has been
sufficient to meet liquidity requirements, capital expenditures, research and
development costs and expansion of operations. Cash flow from operations totaled
$1,753,483, $1,672,589 and $1,463,930 for the fiscal years ended August 31,
1997, 1996 and 1995, respectively. This net cash flow resulted principally from
net income.

         Net cash used in investing activities totaled $985,457, $98,151 and
$147,722 for the fiscal years ended August 31, 1997, 1996 and 1995,
respectively. The primary uses of cash in fiscal 1997 were investments in
corporate joint ventures, trading investment, property and the issuance of a
note receivable to a joint venture partner. The primary uses of cash in fiscal
1996 and 1995 were investments in corporate joint ventures and additions to
property. In fiscal 1996, the Company's expenditures of cash for investing
activities were offset by payments of $743,875 on notes receivable from the
purchase of Common Stock.

         Net cash used in financing activities was $529,979, $698,219 and
$687,458 for the fiscal years ended August 31, 1997, 1996 and 1995,
respectively. The primary uses of cash resulted from the payment of dividends in
fiscal 1997, 1996 and 1995 and the repurchase of Common Stock in fiscal 1997,
1996 and 1995. The primary source of cash provided by financing activities was
proceeds from the issuance of Common Stock upon the exercise of outstanding
stock options and warrants in fiscal 1997, 1996 and 1995, respectively.

         Inflation historically has had little effect on the Company.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In February 1997, the Financial Accounting Standards Board ("FASB")
issued SFAS No. 128, EARNINGS PER SHARE, which is effective for interim and
annual reporting periods ending after December 15, 1997. SFAS No. 128 supersedes
Accounting Principles Board Opinion No. 15, EARNINGS PER SHARE, and replaces the
presentation of primary earnings per share with a presentation of basic earnings
per share. It also requires dual presentation for all entities with complex
capital structures and provides guidance on other computational changes. The
implementation of SFAS No. 128 is expected to increase earnings per share by
$0.01 per share and an immaterial amount for the years ended August 31, 1997 and
1996, respectively.

NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED AUGUST 31, 1997, 1996, AND 1995


1.       NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

         BUSINESS OPERATIONS - Northern Technologies International Corporation
         (the Company) is engaged in the development, manufacture, and marketing
         of proprietary corrosion inhibiting products and electronic sensing
         instruments.

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

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

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

         Buildings and improvements                    5-20 years
         Machinery and equipment                       2-10 years

         INVESTMENTS IN CORPORATE JOINT VENTURES - Investments in corporate
         joint ventures are accounted for using the equity method. Intercompany
         profits on inventories held by the corporate joint ventures which were
         purchased from the Company have been eliminated based on the Company's
         ownership percentage in each corporate joint venture.

         INVESTMENTS IN FOREIGN AND EUROPEAN HOLDING COMPANY - Investments in
         foreign and European holding company are accounted for using the equity
         method.

         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 - The functional currency of the corporate
         joint ventures and the foreign company is the applicable local
         currency, except for the Company's corporate joint venture in Brazil,
         for which the functional currency is the U.S. dollar. 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 excluded
         from net income and accumulated in a separate component of
         stockholders' equity.


<PAGE>


         REVENUE RECOGNITION - Revenue is recognized when the products are
         shipped. A portion of the gross profit on products shipped to the
         Company's corporate joint ventures is deferred until such products are
         sold by the corporate joint ventures.

         RESEARCH AND DEVELOPMENT - Research and development expenditures are
         expensed as incurred. Total research and development expenses were
         $432,943, $370,045, and $353,887 for the years ended August 31, 1997,
         1996, and 1995, respectively.

         FEES FOR TECHNICAL AND OTHER SUPPORT TO CORPORATE JOINT VENTURES - Fees
         for technical and other support to corporate joint ventures are
         recognized at the time the service is provided.

         INCOME PER SHARE - Income per share of common stock was computed by
         dividing net income by the weighted average number of common and common
         equivalent shares outstanding during each year. This amount includes
         common stock equivalents of 68,898, 56,830, and 106,512 for the years
         ended August 31, 1997, 1996, and 1995, respectively, resulting from the
         assumed exercise of outstanding options and warrants using the treasury
         stock method.

         USE OF ESTIMATES - The preparation of the financial statements in
         conformity with generally accepted accounting principles 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.

         FAIR VALUE DISCLOSURE OF FINANCIAL INSTRUMENTS - Cash and cash
         equivalents, receivables, and current liabilities are carried at
         amounts which reasonably approximate their fair value due to their
         short-term nature.

         NEW ACCOUNTING STANDARD - In February 1997, the Financial Accounting
         Standards Board issued SFAS No. 128, EARNINGS PER SHARE, which is
         effective for interim and annual reporting periods ending after
         December 15, 1997. SFAS No. 128 supersedes Accounting Principles Board
         Opinion No. 15, EARNINGS PER SHARE, and replaces the presentation of
         primary earnings per share with a presentation of basic earnings per
         share. It also requires dual presentation for all entities with complex
         capital structures and provides guidance on other computational
         changes. The implementation of SFAS No. 128 is expected to increase
         basic income per share by $.01 per share and an immaterial amount for
         the years ended August 31, 1997 and 1996, respectively, due to the
         elimination of common stock equivalents from the calculation.

2.       INVENTORIES

         Inventories at August 31 consist of the following:

                                                    1997          1996

         EUROPEAN HOLDING COMPANY - During 1997, the Company invested $254,639
         for a 50% ownership interest in a European holding company. To date,
         the entity has been inactive and its assets as of August 31, 1997
         consist primarily of cash and cash equivalents.

5.       STOCKHOLDERS' EQUITY

         During 1997, 1996, and 1995, the Company acquired and retired 9,000;
         61,165; and 113,000 shares of common stock for $53,100; $313,301; and
         $711,900, respectively.

         During 1997 and 1996, certain employees received 3,000 and 2,500 shares
         of common stock, respectively, in return for services provided and
         expensed in 1996 and 1995, respectively. The value of the common stock
         issued, $15,375 and $12,813 in 1997 and 1996, respectively, was
         determined based on the market value of the Company's common stock.

         A note receivable of $129,807 (including accrued interest of $4,432)
         resulting from the exercise of warrants has been shown as a reduction
         of stockholders' equity. The note receivable bears interest at a rate
         of 11% and is due on demand. The increase in accrued interest
         receivable on the outstanding note receivable as of August 31, 1997 and
         1996 has been fully reserved for, due to the uncertainty as to when the
         interest would be paid.

         During 1994, the Company's Board of Directors and shareholders approved
         a stock option plan (the Plan) providing for the granting of options to
         purchase 250,000 shares of common stock. Under the Plan, incentive
         stock options and nonqualified stock options may be granted to
         directors, officers, nonofficer employees, and others. The options have
         a term of five years and become exercisable ratably over a three- or
         four-year period beginning on the first annual anniversary date of the
         grant. Options are granted at prices equal to the market value of the
         stock on the date of grant.

         The Company applies Accounting Principles Board (APB) Opinion No. 25
         and related interpretations in accounting for the Plan. No compensation
         cost has been recognized for options issued under the Plan when the
         exercise price of the options granted are at least equal to the fair
         value of the common stock on the date of grant. Had compensation cost
         for the Company's stock option plan been determined based on the fair
         value at the grant date for awards in the years ended August 31,
         consistent with the provisions of SFAS No. 123, the Company's net
         income would have changed to the pro forma amounts indicated below:

                                                        1997            1996

         During the fourth quarters of 1997 and 1996, the Company adjusted the
         carrying value of inventory as a result of a complete annual physical
         count and valuation. This annual counting and pricing was more
         comprehensive than that which had been conducted on an interim basis.
         As a result, the Company decreased cost of sales by approximately
         $50,000 and $76,000 in the fourth quarters of 1997 and 1996,
         respectively. It is not practicable to determine the periods of the
         fiscal year to which these adjustments relate.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

         On October 1, 1976, the Company entered into a Manufacturer's
Representative Agreement with The Saxxon Organization, Incorporated (the
"Agreement"). The Agreement has no expiration date and may be terminated by
either party upon 60 days written notice. Effective January 9, 1980, the
Agreement was assigned to Inter Alia, a financial and management consulting firm
of which Philip M. Lynch, the Chairman of the Board of Directors of the Company,
is a stockholder, officer and director. Under the Agreement, Inter Alia (or the
"Representative") is entitled to commissions from the Company on the net
proceeds of sales of the Company's product generated by Inter Alia. The
Representative acts as an independent manufacturer's representative of the
Company. It has a non-exclusive worldwide right to offer for sale and solicit
orders for the Company's products in accordance with prices determined by the
Company. The Representative is responsible for all of its own operating expenses
with no entitlement for reimbursement from the Company. The Representative has
not effected any sales within the United States. The Representative's effort has
developed sales outside the United States, specifically in France, which
resulted in commissions of approximately $42,582, $52,950 and $52,057 for the
fiscal years ended August 31, 1997, 1996 and 1995, respectively. In light of the
Company's own domestic sales effort and its distributor network within the
United States, the Company does not anticipate the Representative developing any
sales within the United States. Additionally, the Company's expanding
international joint venture program may also limit opportunities abroad for the
Representative. Thus, the Company does not anticipate that the Representative
will develop any significant sales volume for the Company.

         On August 31, 1984, Inter Alia purchased 119,083 shares of the Common
Stock and paid therefor by signing a promissory note. The promissory note (the
"Note") has a face value of $125,375 and bears interest at 11% per year. The
Note was originally due on December 31, 1992 and is currently due on demand. The
outstanding balance of the Note, including accrued interest of $92,579, was
$217,954 at August 31, 1997.

         Gerhard Hahn, a director of the Company, is a shareholder and General
Manager of Knuppel KG. Knuppel KG is a 50% partner with the Company in a joint
venture in Germany. The German joint venture entity has granted a loan of
750,000 DM to Knuppel KG. The loan is secured by Knuppel KG's equity in the
German joint venture and bears interest at 7.5% per annum.
