<p style="font-size: 10pt; margin: 0pt 0">In May 2014, the Financial Accounting Standards Board (FASB) issued <i>Revenue from Contracts
with Customers, Topic 606</i> (Accounting Standards Update (ASU) No. 2014-09), which provides a framework for the recognition of
revenue, with the objective that recognized revenues properly reflect amounts an entity is entitled to receive in exchange for
goods and services. This guidance, which includes additional disclosure requirements regarding revenue, cash flows and obligations
related to contracts with customers, was originally to be effective for the Company beginning in fiscal year 2018. In July 2015,
the FASB confirmed a one-year deferral of the effective date of the new revenue standard which also allows early adoption as of
the original effective date. The updated guidance will be effective for the Company&#8217;s first quarter of 2019. The Company
is currently evaluating the impact of adopting ASU 2014-09 on its consolidated financial statements, but believes there will be
no material impact, if any.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">In July 2015, the FASB issued ASU No. 2015-11, &#8220;<i>Inventory</i>&#8221;, which
modifies the subsequent measurement of inventories recorded under a first-in-first-out or average cost method. Under the new standard,
such inventories are required to be measured at the lower of cost and net realizable value. The new standard is effective for the
Company&#8217;s fiscal year 2018, with prospective application. The Company does not expect the adoption of the provisions of ASU
2015-11 to have a material impact on its consolidated financial statements.</p>

Standards Update (ASU) No. 2016-02, &#8220;<i>Leases</i>.&#8221; ASU No. 2016-02 was issued to increase transparency and comparability
among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability
and a right-of-use asset (as defined). ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including
interim periods within those fiscal years, with earlier application permitted. Upon adoption, the lessee will apply the new standard
retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company

<p style="font-size: 10pt; margin: 0pt 0">In March 2016, the FASB issued ASU No. 2016-07, &#8220;<i>Investments &#8211; Equity
Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting</i>.&#8221; Among other things,
the amendments in ASU 2016-07 eliminate the requirement that when an investment qualifies for use of the equity method as a result
of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations,
and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods
that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional
interest in the investee to the current basis of the investor&#8217;s previously held interest and adopt the equity method of accounting
as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method
of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale
equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain
or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The
amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December
15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest
or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The Company is currently
assessing the impact that ASU 2016-07 will have on its consolidated financial statements.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>&nbsp;</b></p>

<p style="font-size: 10pt; margin: 0pt 0">The Company has two stock-based compensation plans under which stock options and other
stock-based awards have been granted, the Northern Technologies International Corporation Amended and Restated 2007 Stock Incentive
Plan and the Northern Technologies International Corporation Employee Stock Purchase Plan (the ESPP). The Compensation Committee
of the Board of Directors and the Board of Directors administer these plans.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The 2007 Plan provides for the grant of incentive stock options, non-statutory stock
options, stock appreciation rights, restricted stock, stock unit awards, performance awards and stock bonuses to eligible recipients
to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities for equity participation
in the Company, and to reward those individuals who contribute to the achievement of the Company&#8217;s economic objectives. Subject
to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company&#8217;s common stock are issuable
under the 2007 Plan. Options granted under the 2007 Plan generally have a term of ten years and become exercisable over a three-
or four-year period beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices
equal to the market value of the Company&#8217;s common stock on the date of grant. The Company issues new shares upon the exercise
of options. As of May 31, 2016, only stock options and stock bonuses had been granted under the 2007 Plan.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The maximum number of shares of common stock of the Company available for issuance under
the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning
on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common
stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans
of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting
purposes. The Company issued 2,439 and 1,948 shares on September 1, 2015 and 2014, respectively, under the ESPP. The Company issued
3,144 shares on March 1, 2016 under the ESPP.</p>

common stock during the nine months ended May 31, 2016 and 2015, respectively. The fair value of option grants is determined at
date of grant, using the Black-Scholes option pricing model with the assumptions listed below.&nbsp; The Company recognized compensation
expense of $325,576 and $378,421 during the nine months ended May 31, 2016 and 2015, respectively, related to the options that
vested during such time period. As of May 31, 2016, the total compensation cost for nonvested options not yet recognized in the
Company&#8217;s consolidated statements of operations was $341,261, net of estimated forfeitures. Stock-based compensation expense
of $101,861 is expected through the remainder of fiscal year 2016, and $159,600 and $79,800 is expected to be recognized during
fiscal 2017 and fiscal 2018, respectively, based on outstanding options as of May 31, 2016. Future option grants will impact the
compensation expense recognized. Stock-based compensation expense is included in general and administrative expense on the consolidated
statements of operations.</p>

approved the material terms of an annual bonus plan for the Company&#8217;s executive officers as well as certain officers and
employees for the fiscal year ending August 31, 2016. For fiscal 2016 as in past years, the total amount available under the bonus
plan for all plan participants, including executive officers, is dependent upon the Company&#8217;s earnings before interest, taxes
and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted
EBITOI). Each plan participant&#8217;s percentage of the overall bonus pool is based upon the number of plan participants, the
individual&#8217;s annual base salary and the individual&#8217;s position and level of responsibility within the company. In the
case of each of the Company&#8217;s executive officer participants, 75% of the amount of their individual bonus payout will be
determined based upon the Company&#8217;s actual Adjusted EBITOI for fiscal 2016 compared to a pre-established target Adjusted
EBITOI for fiscal 2016 and 25% of the payout will be determined based upon such executive officer&#8217;s achievement of certain
pre-established individual performance objectives. The payment of bonuses under the plan are discretionary and may be paid to executive
officer participants in both cash and shares of the Company&#8217;s common stock, the exact amount and percentages will be determined
by the Company&#8217;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&#8217;s
consolidated financial statements for fiscal 2016. There was $215,000 accrued for management bonuses for the nine months ended
May 31, 2016 compared to an accrual of $466,000 for management bonuses for the nine months ended May 31, 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>Business Overview</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b>&nbsp;</b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC develops and markets proprietary environmentally beneficial products and services
in over 60 countries either directly or via a network of subsidiaries, joint ventures, independent distributors and agents. NTIC&#8217;s
primary business is corrosion prevention marketed mainly under the ZERUST&#174; brand. NTIC has been selling its proprietary ZERUST&#174;
products and services to the automotive, electronics, electrical, mechanical, military and retail consumer markets for over 40
years, and in recent years, has targeted and expanded into the oil and gas industry. NTIC also markets and sells a portfolio of
biobased and compostable (fully biodegradable) polymer resins and finished products under the Natur-Tec&#174; brand. These products
are intended to reduce NTIC&#8217;s customers&#8217; carbon footprint and provide environmentally sound waste disposal options.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s ZERUST&#174; rust and corrosion inhibiting products include plastic and paper
packaging, liquids and coatings, rust removers and cleaners, diffusers and engineered solutions designed specifically for the oil
and gas industry. NTIC also offers worldwide on-site technical consulting for rust and corrosion prevention issues. NTIC&#8217;s
technical service consultants work directly with the end users of NTIC&#8217;s ZERUST&#174; rust and corrosion inhibiting products
to analyze their specific needs and develop systems to meet their technical requirements. In North America, NTIC sells its ZERUST&#174;
corrosion prevention solutions through a direct sales force as well as a network of independent distributors and agents. Internationally,
NTIC sells its ZERUST&#174; corrosion prevention solutions through its wholly-owned subsidiary in China, NTIC (Shanghai) Co., Ltd.
(NTIC China), its majority-owned joint venture holding company for NTIC&#8217;s joint venture investments in the Association of
Southeast Asian Nations (ASEAN) region, its majority-owned subsidiary in Brazil, Zerust Preven&#231;&#227;o de Corros&#227;o
S.A. (Zerust Brazil), and joint venture arrangements in North America, Europe and Asia.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">One of NTIC&#8217;s strategic initiatives is to expand into and penetrate other markets
for its ZERUST&#174; corrosion prevention solutions. Consequently, for the past several years, NTIC has focused its sales and marketing
efforts on the oil and gas industry, as the infrastructure that supports that industry is typically constructed using metals that
are highly susceptible to corrosion. NTIC believes that its ZERUST&#174; corrosion prevention solutions will minimize maintenance
downtime on critical oil and gas industry infrastructure, extend the life of such infrastructure and reduce the risk of environmental
pollution due to corrosion leaks.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC markets and sells its ZERUST&#174; rust and corrosion prevention solutions to customers
in the oil and gas industry across several countries either directly, through its subsidiaries or through its joint venture partners
and other strategic partners. The sale of ZERUST&#174; corrosion prevention solutions to customers in the oil and gas industry typically
involves a long sales cycle, often including a one- to multi-year trial period with each customer and a slow integration process
thereafter.</p>

patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec&#174;
biopolymer resin compound portfolio includes formulations that have been optimized for a variety of applications including blown-film
extrusion, extrusion coating, injection molding, and engineered plastics. These resins are fully biodegradable in a composting
environment and are currently being used to produce finished products including can liners, shopping and grocery bags, lawn and
leaf bags, pet waste collection bags, cutlery, packaging foam and coated paper products. In North America, NTIC markets its Natur-Tec&#174;
resins and finished products primarily through a network of regional and national distributors as well as independent agents. NTIC
continues to see significant opportunities for finished bioplastic products and, therefore, continues to strengthen and expand
its North American distribution network for finished Natur-Tec&#174; bioplastic products. Internationally, NTIC sells its Natur-Tec&#174;
resins and finished products both directly and through its majority- owned subsidiary in India, Natur-Tec India Private Limited
(Natur-Tec India), and through certain joint ventures. In November 2014, NTIC entered into an agreement with NatureWorks LLC for
joint marketing and sales of Ingeo&#174; based packaging solutions to customers in India. With recent Indian government mandates
banning use of non-biodegradable plastics in certain types of food and consumer packaging, NTIC expects the market in India for
bioplastic packaging solutions to grow substantially.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>Termination of Chinese Joint Venture</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b>&nbsp;</b></p>

<p style="font-size: 10pt; margin: 0pt 0">On January 2, 2015, NTIC announced that, effective as of December 31, 2014, it is selling
its ZERUST&#174; products and services in China through a wholly-owned subsidiary, NTIC (Shanghai) Co., Ltd., and has terminated
its joint venture agreements with Tianjin-Zerust Anticorrosion Co., Ltd. (Tianjin Zerust). NTIC and NTI Asean LLC have filed a
lawsuit against Mr. Tao Meng, a Chinese national and the former joint venture entity&#8217;s other shareholder, and his spouse
in the Chinese court of Tianjin, seeking, among other things, an orderly liquidation of Tianjin Zerust.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC indirectly has a 30% ownership interest in Tianjin Zerust through its 60% owned
holding company subsidiary, NTI Asean LLC. Commencing during the second quarter of fiscal 2015, NTIC&#8217;s consolidated financial
statements include the financial results of NTIC China.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC anticipates that it may take several quarters to transition many of the previous
customers of Tianjin Zerust to NTIC China and no assurance can be provided that NTIC China will be able to achieve the net sales
and income levels previously achieved by Tianjin Zerust. For fiscal 2014, Tianjin Zerust had net sales of $15.9 million and net
income of $1.3 million. The operating income of the joint venture before paying royalties in an aggregate amount of $4.2 million
to all shareholders was over $5.5 million; NTIC&#8217;s indirect ownership of Tianjin Zerust is 30%.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">During fiscal 2015, NTIC incurred approximately $1,640,000 and during the first nine
months of fiscal 2016, NTIC incurred approximately $1,425,000 in expenses related either directly or indirectly to the establishment
and initial business operations of NTIC China, the termination of the joint venture agreements with Tianjin Zerust, its pending
litigation against Mr. Tao Meng and his spouse and Cortec Corporation, and the anticipated liquidation of Tianjin Zerust. These
expenses are recorded as selling, general and administrative expenses and expenses incurred in support of joint ventures on the
consolidated statements of operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC expects that its operating results may be volatile over the next few quarters as
a result of NTIC&#8217;s Chinese operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;<b> </b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b>NTIC&#8217;s Joint Venture Network</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b>&nbsp;</b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC participates in 19 active joint venture arrangements in North America, Europe and
Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory to which it is assigned.
While most of NTIC&#8217;s joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also
sell NTIC&#8217;s Natur-Tec&#174; resin compounds. NTIC has historically funded its investments in joint ventures with cash generated
from operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s receipt of funds from its joint ventures is dependent upon fees for services
that NTIC provides to its joint ventures, based primarily on the net sales of the individual joint ventures, and NTIC&#8217;s receipt
of dividend distributions from the joint ventures. The fees for services provided to joint ventures are determined based on either
a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC&#8217;s joint venture in
Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for such services. NTIC recognizes equity income from its joint ventures
based on the overall profitability of its joint ventures. Such profitability is subject to variability from quarter to quarter
which subjects NTIC&#8217;s earnings to variability from quarter to quarter. The profits of NTIC&#8217;s joint ventures are shared
by the respective joint venture owners in accordance with their respective ownership percentages. NTIC typically directly or indirectly
owns 50% or less of each of its joint venture entities and thus does not control the decisions of these entities regarding whether
to pay dividends and, if paid, how much they should be in a given year. The payment of a dividend by an entity is determined by
a joint vote of the owners and is not at the sole discretion of NTIC.</p>

in eight entities that operate in the following eight territories located in the ASEAN region: China (although liquidation was
initiated December 31, 2014), Indonesia, South Korea, Malaysia, Philippines, Singapore, Taiwan and Thailand. NTIC holds 90% of

operating decision maker, reports and manages NTIC&#8217;s operations in two reportable business segments based on products sold,

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s consolidated net sales increased 4.9% and 5.4% during the three and nine
months ended May 31, 2016, respectively, compared to the three and nine months ended May 31, 2015. These increases were primarily
a result of increased sales at NTIC China and increased sales of Natur-Tec&#174; products, partially offset by decreased sales of
Zerust industrial products. During the three and nine months ended May 31, 2016, 82.7% and 83.5% of NTIC&#8217;s consolidated net
sales, respectively, were derived from sales of ZERUST&#174; products and services, which increased 1.5% and 2.4% to $7,185,955
and $19,548,974 during the three and nine months ended May 31, 2016, respectively, compared to $7,076,760 and $19,098,816 during
the three and nine months ended May 31, 2015, respectively, due to increased demand from new customers, primarily at NTIC China.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC has focused its sales efforts of ZERUST&#174; products and services by strategically
targeting customers with specific corrosion issues in new market areas, including the oil and gas industry and other industrial
sectors that offer sizable growth opportunities. NTIC&#8217;s consolidated net sales for the nine months ended May 31, 2016 included
$1,229,426 of sales made to customers in the oil and gas industry compared to $1,382,423 for the nine months ended May 31, 2015.
Overall demand for ZERUST&#174; products and services depends heavily on the overall health of the markets in which NTIC sells its
products, including the automotive, oil and gas, agriculture, and mining markets in particular. In addition, we believe demand
for ZERUST&#174; products and services in the oil and gas industry is dependent upon oil prices, with low oil prices causing existing
or potential customers to delay purchases and installations.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">During the three and nine months ended May 31, 2016, 17.3% and 16.5%, of NTIC&#8217;s
consolidated net sales were derived from sales of Natur-Tec&#174; products compared to 14.5% and 14.0% during the three and nine
months ended May 31, 2015, respectively. Net sales of Natur-Tec&#174; products increased 25.0% and 23.9% during the three and nine
months ended May 31, 2016 compared to the three and nine months ended May 31, 2015, respectively. These increases were primarily
due to increases in finished product sales in North America and finished product sales at NTIC&#8217;s majority owned subsidiary
in India, Natur-Tec India Private Limited (Natur-Tec India).</p>

<p style="font-size: 10pt; margin: 0pt 0">Cost of goods sold as a percentage of net sales decreased to 66.5% during the three months
ended May 31, 2016 compared to 67.6% during the three months ended May 31, 2015 and increased to 68.0% during the nine months ended
May 31, 2016 compared to 67.8% during the prior fiscal year period. These small variances were primarily as a result of small variances
in raw material prices during the various periods and better margins on sales of Natur-Tec&#174; products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s equity in income of joint ventures decreased 3.5% and 25.1% to $1,664,464
and $3,600,884, respectively, during the three and nine months ended May 31, 2016 compared to $1,724,915 and $4,806,247 during
the three and nine months ended May 31, 2015. These decreases were primarily a result of decreases in profitability at the joint
ventures, decreases associated with the anticipated liquidation of Tianjin Zerust and adverse effects of foreign currency exchange
rate fluctuations, including in particular the Euro compared to the U.S. dollar. Equity in income provided by Tianjin Zerust was
$0 for the nine months ended May 31, 2016 compared to $132,824 for the nine months ended May 31, 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC recognized a 3.7% increase and a 14.1% decrease in fees for services provided to
joint ventures during the three and nine months ended May 31, 2016, compared to the three and nine months ended May 31, 2015, respectively.
The decrease for the nine-month period was primarily a result of the anticipated liquidation of Tianjin Zerust and a decrease in
sales at the joint ventures. Fees for services provided to Tianjin Zerust were $0 for the nine months ended May 31, 2016 compared
to $516,000 for the nine months ended May 31, 2015. Additionally, there was a decrease in sales at the joint ventures, which were
$66,223,514 during the nine months ended May 31, 2016, compared to $75,974,770 for the nine months ended May 31, 2015. This decrease
in the net sales of NTIC&#8217;s joint ventures was primarily the result of adverse effects of foreign currency exchange rate fluctuations
and weaker economic trends, especially in Europe. This decrease resulted in a corresponding decrease in fees for services provided
to joint ventures as such fees are a function of net sales of NTIC&#8217;s joint ventures.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s total operating expenses increased 3.6% and 2.6% to $4,697,018 and $13,796,320
during the three and nine months ended May 31, 2016 compared to the nine months ended May 31, 2015, respectively. This increase
was primarily the result of the expenses related to the formation and establishment of NTIC China and the anticipated liquidation
of Tianjin Zerust, partially offset by decreases in expenses in North America due to companywide cost cutting initiatives. Such
expenses in China consisted primarily of legal and personnel expenses associated with the establishment of the subsidiary, the
hiring of new personnel and initial operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC expenses all costs related to product research and development as incurred. NTIC
incurred $3,349,572 and $2,968,879 of expense during the nine months ended May 31, 2016 and 2015, respectively, in connection with
its research and development activities. NTIC anticipates that it will spend between $4,000,000 and $4,400,000 in total during
fiscal 2016 on research and development activities related to its new technologies.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Net income attributable to NTIC was $917,373, or $0.20 per diluted common share, for
the three months ended May 31, 2016 compared to $905,435, or $0.20 per diluted common share, for the three months ended May 31,
2015. Net income attributable to NTIC decreased 67.8%, to $575,233, or $0.13 per diluted common share, for the nine months ended
May 31, 2016 compared to $1,785,056 or $0.39 per diluted common share, for the nine months ended May 31, 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC anticipates that its quarterly net income will continue to remain subject to significant
volatility primarily due to the financial performance of its subsidiaries and joint ventures and sales of its ZERUST&#174; products
and services into the oil and gas industry and Natur-Tec&#174; bioplastics products, which sales fluctuate more on a quarterly basis
than the traditional ZERUST&#174; business. NTIC also anticipates that its operating results during the next few quarters will be
particularly volatile as a result of the changes in its Chinese operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">During the three and nine months ended May 31, 2016, 82.7% and 83.5% of NTIC&#8217;s
consolidated net sales, respectively, were derived from sales of ZERUST<sup>&#174;</sup> products and services, which increased
1.5% and 2.4% to $7,185,955 and $19,548,974 during the three and nine months ended May 31, 2016, respectively, compared to $7,076,760
and $19,098,816 during the three and nine months ended May 31, 2015, respectively. These increases were due to increased demand
from existing customers and the addition of new customers, primarily at NTIC China. NTIC has strategically focused its sales efforts
for ZERUST<sup>&#174;</sup> products and services on customers with sizeable corrosion problems in industry sectors that offer sizable
growth opportunities, including the oil and gas sector. Overall demand for ZERUST<sup>&#174;</sup> products and services depends
heavily on the overall health of the market segments to which NTIC sells its products, including the automotive, oil and gas, agriculture,
and mining markets in particular. In addition, we believe demand for ZERUST&#174; products and services in the oil and gas industry
is dependent upon oil prices, with low oil prices causing existing or potential customers to delay purchases and installations.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s net sales to the oil and gas industry sector were up slightly for the three-month
comparison and decreased for the nine-month comparison. NTIC anticipates that its sales of ZERUST&#174; products and services into
the oil and gas industry will continue to remain subject to significant volatility from quarter to quarter as sales are recognized.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">During the three and nine months ended May 31, 2016, 17.3% and 16.5% of NTIC&#8217;s
consolidated net sales, respectively, were derived from sales of Natur-Tec&#174; products, which increased 25.0% and 23.9% to $1,500,620
and $3,866,972 during the three and nine months ended May 31, 2016, respectively, compared to the three and nine months ended May
31, 2015. These increases were due to increased demand from Natur-Tec customers in North America and India. Demand for Natur-Tec&#174;
products around the world depends primarily on market acceptance and the reach of NTIC&#8217;s distribution network. Because of
the typical size of individual orders and overall size of NTIC&#8217;s net sales derived from sales of Natur-Tec&#174; products,
the timing of one or more orders could materially affect NTIC&#8217;s quarterly sales of Natur-Tec&#174; products and the comparisons
to prior fiscal year quarters.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Cost of Goods Sold</i>. Cost of goods sold increased 3.3% and 5.7% for the three and
nine months ended May 31, 2016, respectively, compared to the three and nine months ended May 31, 2015 primarily as a result of
increased net sales as described above. Cost of goods sold as a percentage of net sales decreased to 66.5% during the three months
ended May 31, 2016 compared to 67.6% during the three months ended May 31, 2015 and increased to 68.0% during the nine months ended
May 31, 2016 compared to 67.8% during the nine months ended May 31, 2015. These changes in cost of goods sold as a percentage of
net sales were primarily the result of changes in raw material costs and margins on sales of Natur-Tec&#174; products.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Equity in Income of Joint Ventures.</i> NTIC&#8217;s equity in income of joint ventures
decreased 3.5% and 25.1% to $1,664,464 and $3,600,884 during the three and nine months ended May 31, 2016, respectively, compared
to equity in income of joint ventures of $1,724,915 and $4,806,247 during the three and nine months ended May 31, 2015, respectively.
These decreases were primarily a result of decreases in the profitability at the joint ventures, a decrease in profitability associated
with the anticipated liquidation of Tianjin Zerust and adverse effects of foreign currency exchange rate fluctuations, including
in particular the Euro compared to the U.S. dollar. Equity in income provided by Tianjin Zerust was $0 for the nine months ended
May 31, 2016 compared to $132,824 for the nine months ended May 31, 2015. Of the total equity in income of joint ventures, NTIC
had equity in income of joint ventures of $2,714,905 attributable to EXCOR during the nine months ended May 31, 2016 compared to
$3,152,489 attributable to EXCOR during the nine months ended May 31, 2015. NTIC had equity in income of all other joint ventures
of $885,979 during the nine months ended May 31, 2016 compared to $1,520,934 during the nine months ended May 31, 2015.</p>

provided to joint ventures of $1,351,913 and $3,808,384 during the three and nine months ended May 31, 2016, respectively, compared
to $1,303,964 and $4,432,494 during the three and nine months ended May 31, 2015, respectively, representing an increase of 3.7%
and decrease of 14.1%, respectively. The decrease for the nine-month comparison was primarily a result of the anticipated liquidation
Tianjin Zerust as fees for services provided to joint ventures from Tianjin Zerust were $0 for the nine months ended May 31, 2016
compared to $516,000 for the nine months ended May 31, 2015. Additionally, there was a decrease in total sales at all joint ventures
for the nine-month comparison which adversely affected fees for services provided to joint ventures since fees for services provided
to joint ventures are largely a function of the net sales of NTIC&#8217;s joint ventures. Total sales at all joint ventures were
$24,223,090 and $66,223,514 during the three and nine months ended May 31, 2016, respectively, compared to $23,796,532 and $75,974,770
for the three and nine months ended May 31, 2015, respectively. Net sales of NTIC&#8217;s joint ventures decreased for the nine-month
comparison due primarily to the adverse effects of foreign currency exchange rate fluctuations and weaker economic trends, especially
in Europe. Net sales of NTIC&#8217;s European joint ventures were adversely affected by a downturn in European manufacturing. Future
net sales of NTIC&#8217;s joint ventures, including in particular its European joint ventures, may be adversely affected by the
recent referendum vote of the United Kingdom to exit the European Union. Sales of NTIC&#8217;s joint ventures are not included
in NTIC&#8217;s product sales and are not combined with NTIC&#8217;s sales in NTIC&#8217;s consolidated financial statements or
in any description of NTIC&#8217;s sales. Of the total fee income for services provided to joint ventures, fees of $664,812 were
attributable to EXCOR during the nine months ended May 31, 2016 compared to $660,135 attributable to EXCOR during the nine months
ended May 31, 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Selling Expenses</i>. NTIC&#8217;s selling expenses increased 5.1% and 8.1% for the
three and nine months ended May 31, 2016, respectively, compared to the same respective periods in fiscal 2015 due to increases
in compensation and employee benefits, lab testing related expenses, commission expenses, travel and related expenses, and consulting
expenses, each due in part to NTIC&#8217;s Chinese operations. Selling expenses as a percentage of net sales increased to 17.4%
and 19.3% for the three and nine months ended May 31, 2016, respectively, from 17.3% and 18.8% and during the three and nine months
ended May 31, 2015, respectively. The increases in selling expenses as a percentage of net sales were due primarily to the increase
in net sales partially offset by the increase in selling expenses as previously described.</p>

decreased 0.7% and increased 5.5% for the three and nine months ended May 31, 2016, respectively, compared to the same respective
periods in fiscal 2015. NTIC implemented cost cutting measures companywide in the third quarter of fiscal year 2016, which partially
offset the expenses incurred in connection with NTIC&#8217;s Chinese operations. As a percentage of net sales, general and administrative
expenses decreased to 19.5% and remained unchanged at 21.6% for the three and nine months ended May 31, 2016, respectively, from
20.6% and 21.6% for the three and nine months ended May 31, 2015, respectively. The decrease in general and administrative expenses
as a percentage of net sales for the three-month comparison was due primarily to the decrease in general and administrative expenses
as previously described.</p>

to $327,586 and $1,510,830 during the three and nine months ended May 31, 2015, respectively, representing decreases of 18.6% and
41.7%, respectively. These decreases were primarily due to expenses incurred by NTIC&#8217;s Chinese operations being classified
as selling expenses and general and administrative expenses upon the formation of NTIC&#8217;s subsidiary in January 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Income Tax Expense</i>. Income tax expense was $225,395 and $262,359 during the three
and nine months ended May 31, 2016, respectively, compared income tax expense of $114,180 and $495,478 during the three and nine
months ended May 31, 2015, respectively. Income tax expense was calculated based on management&#8217;s estimate of NTIC&#8217;s
annual effective income tax rate. NTIC&#8217;s annual effective income tax rate during the three and nine months ended May 31,
2016 and 2015 was lower than the statutory rate primarily due to NTIC&#8217;s equity in income of joint ventures being recognized
based on after-tax earnings of these entities. To the extent undistributed earnings of NTIC&#8217;s joint ventures are distributed
to NTIC, any material additional income tax liability after the application of foreign tax credits is not expected. NTIC records
a tax valuation allowance when it is more likely than not that some portion or all of its deferred tax assets will not be realized
to reduce deferred tax assets to the amount expected to be realized. NTIC determined based on all available evidence, including
historical data and projections of future results, that it is more likely than not that all of its deferred tax assets, except
for its foreign tax credit carryforwards and Minnesota state research and development credit carryforwards, will be fully realized.
In addition, NTIC determined based upon all available evidence, including new IRS guidance, historical results, projected future
taxable income and foreign tax credit utilization, that it was not more likely than not that the federal research and development
credits would be utilized during the carryforward period and as a result, a valuation allowance was recorded against all of NTIC&#8217;s
federal research and development credits. In addition, NTIC continues to believe that its deferred tax asset related to foreign
tax credit carryforwards will not be realized due to insufficient federal taxable income within the carryforward period and the
fact that for ordering purposes the foreign tax credit carryforwards are not allowed to be used until after any current year foreign
tax credits are utilized.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC considers the earnings of certain foreign joint ventures to be indefinitely invested
outside the United States on the basis of estimates that NTIC&#8217;s future domestic cash generation will be sufficient to meet
its future domestic cash needs. As a result, U.S. income and foreign withholding taxes have not been recognized on the cumulative
undistributed earnings of $15,892,135 and $18,483,377 at May 31, 2016 and August 31, 2015, respectively. To the extent undistributed
earnings of NTIC&#8217;s joint ventures are distributed in the future, they are not expected to result in any material additional
income tax liability after the application of foreign tax credits.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Other Comprehensive (Loss) Income - Foreign Currency Translations Adjustment. </i>The
significant changes in the foreign currency translations adjustment were due to the strengthening of the U.S. dollar compared to
the Euro and other foreign currencies during the three and nine months ended May 31, 2016 compared to the same respective periods
in fiscal 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Sources of Cash and Working Capital</i>. As of May 31, 2016, NTIC&#8217;s working
capital was $18,392,783, including $4,626,538 in cash and cash equivalents and $2,239,792 in available for sale securities, compared
to $15,603,771 at August 31, 2015, including $2,623,981 in cash and cash equivalents and $2,027,441 in available for sale securities.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As of May 31, 2016, NTIC had a revolving line of credit with PNC Bank of $3,000,000,
with no amounts outstanding. The line of credit is evidenced by an amended and restated committed line of credit note in the principal
amount of up to $3,000,000. The line of credit has a $1,200,000 standby letter of credit sub-facility, with any standby letters
of credit issued thereunder being at the sole discretion of PNC Bank. The line of credit is subject to standard covenants, including
affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which,
among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers
and consolidations and other matters customarily restricted in such agreements. Under the loan agreement, NTIC is subject to a
minimum fixed charge coverage ratio of 1.10:1.00. As of May 31, 2016, NTIC was in compliance with all debt covenants. On January
6, 2016, PNC Bank extended the maturity date of the line of credit from January 7, 2016 to January 7, 2017. All other terms of
the line of credit and the loan agreement and other documents evidencing the line of credit remain the same. It is anticipated
that, as historically has been the practice, the line of credit will be renewed each year for one additional year for the immediate
foreseeable future.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC believes that a combination of its existing cash and cash equivalents, forecasted
cash flows from future operations, anticipated distributions of earnings, anticipated fees to NTIC for services provided to its
joint ventures, and funds available through existing or anticipated financing arrangements, will be adequate to fund its existing
operations, investments in new or existing joint ventures or subsidiaries, capital expenditures, debt repayments and any stock
repurchases for at least the next 12 months. During the remainder of fiscal 2016, NTIC expects to continue to invest its Chinese
operations, research and development and in marketing efforts and resources into the application of its corrosion prevention technology
into the oil and gas industry and its Natur-Tec&#174; bio-plastics business. In order to take advantage of such new product and
market opportunities to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing
under its revolving line of credit or raising additional financing through the issuance of debt or equity securities. There is
no assurance that any financing transaction will be available on terms acceptable to NTIC or at all, or that any financing transaction
will not be dilutive to NTIC&#8217;s current stockholders.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC traditionally has used the cash generated from its operations, distributions of
earnings and fees for services provided to its joint ventures to fund NTIC&#8217;s new technology investments and capital contributions
to new and existing subsidiaries and joint ventures. NTIC&#8217;s joint ventures traditionally have operated with little or no
debt and have been self-financed with minimal initial capital investment and minimal additional capital investment from their respective
owners. Therefore, NTIC believes it is not likely that there exists any exposure to debt by NTIC&#8217;s joint ventures that could
materially impact their respective operations and/or liquidity.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Uses of Cash and Cash Flows</i>. Net cash provided by operating activities during
the nine months ended May 31, 2016 was $3,053,297, which resulted principally from dividends received from NTIC&#8217;s joint ventures,
NTIC&#8217;s net income, the expensing of fair value of stock options vested, depreciation and amortization expense, and an increase
in accounts payable, partially offset by equity income from NTIC&#8217;s joint ventures, and a decrease in trade receivables and
accrued liabilities. Net cash provided by operating activities during the nine months ended May 31, 2015 was $36,221, which resulted
principally from dividends received from NTIC&#8217;s joint ventures, NTIC&#8217;s net income, fees for services provided to NTIC&#8217;s
joint ventures, stock-based compensation, depreciation and amortization, partially offset by NTIC&#8217;s equity in income from
joint ventures and increases in receivables, inventories, accrued liabilities and prepaid expenses.</p>

<p style="font-size: 10pt; margin: 0pt 0"></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s cash flows from operations are impacted by significant changes in certain
components of NTIC&#8217;s working capital, including inventory turnover and changes in receivables. NTIC considers internal and
external factors when assessing the use of its available working capital, specifically when determining inventory levels and credit
terms of customers. Key internal factors include existing inventory levels, stock reorder points, customer forecasts and customer
requested payment terms, and key external factors include the availability of primary raw materials and sub-contractor production
lead times. NTIC&#8217;s typical contractual terms for trade receivables excluding joint ventures are traditionally 30 days and
for trade receivables from its joint ventures are 90 days. Before extending unsecured credit to customers, excluding NTIC&#8217;s
joint ventures, NTIC reviews customers&#8217; credit histories and will establish an allowance for uncollectible accounts based
upon factors surrounding the credit risk of specific customers and other information. Accounts receivable over 30 days are considered
past due for most customers. NTIC does not accrue interest on past due accounts receivable. If accounts receivables in excess of
the provided allowance are determined uncollectible, they are charged to selling expense in the period that determination is made.
Accounts receivable are deemed uncollectible based on NTIC exhausting reasonable efforts to collect. NTIC&#8217;s typical contractual
terms for receivables for services provided to its joint ventures are 90 days. NTIC records receivables for services provided to
its joint ventures on an accrual basis, unless circumstances exist that make the collection of the balance uncertain in which case
the fee income will be recorded on a cash basis until there is consistency in payments. This determination is handled on a case
by case basis.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC experienced an increase in receivables and a decrease in inventory as of May 31,
2016 compared to August 31, 2015 due to the increase in net sales and a desire to stock more products to shorten lead times and
anticipate customer demand. Trade receivables excluding joint ventures as of May 31, 2016 increased $570,647 compared to August
31, 2015, primarily related to the increase in NTIC&#8217;s net sales. Outstanding trade receivables excluding joint ventures balances
as of May 31, 2016 increased 56 days to an average of 106 days from balances outstanding from these customers as of August 31,
2015. Outstanding trade receivables from joint ventures as of May 31, 2016 increased $73,522 compared to August 31, 2015 primarily
due to the timing of payments. There was an increase of outstanding balances from trade receivables from joint ventures as of May
31, 2016 of an average of 80 days from an average of 93 days from balances outstanding from these customers compared to August
31, 2015. The significant average days outstanding of trade receivables from joint ventures as of May 31, 2016 were primarily due
to the receivable balance at NTIC&#8217;s joint venture in in South Korea and Tianjin Zerust. Because of the lack of financial
and other information received from Tianjin Zerust, it is possible that if and when financial and other information is received
from Tianjin Zerust that NTIC may need to recognize an impairment charge on its receivable from Tianjin Zerust. NTIC estimates
that its maximum exposure in terms of an impairment charge on this receivable would be approximately $114,000.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Outstanding receivables for services provided to joint ventures as of May 31, 2016 decreased
$97,569 compared to August 31, 2015, which resulted in a decrease of 79 days of fees receivable outstanding as of May 31, 2016
to an average of 183 days compared to August 31, 2015.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Net cash used in investing activities for the nine months ended May 31, 2016 was $794,668,
which was primarily the result of additions to property and equipment, cash used in the purchase of available for sale securities,
and additions to patents. Net cash provided by investing activities for the nine months ended May 31, 2015 was $1,755,098, which
was primarily the result of cash proceeds from the sale of available for sale securities, partially offset by additions to property
and equipment and additions to patents.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Net cash used in financing activities for the nine months ended May 31, 2016 was $228,817,
which resulted from a dividend paid to a non-controlling interest and the repurchase of common stock, and offset by proceeds from
NTIC&#8217;s employee stock purchase plan. Net cash used in financing activities for the nine months ended May 31, 2015 was $402,570,
which resulted from a dividend paid to a non-controlling interest, and offset by proceeds from stock option exercises and NTIC&#8217;s
employee stock purchase plan.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Stock Repurchase Program</i>. On January 15, 2015, NTIC&#8217;s Board of Directors
authorized the repurchase of up to $3,000,000 in shares of NTIC common stock through open market purchases or unsolicited or solicited
privately negotiated transactions. This program has no expiration date but may be terminated by NTIC&#8217;s Board of Directors
at any time. During the nine months ended May 31, 2016, NTIC repurchased an aggregate of 7,511 shares for an aggregate purchase
price of $97,400. As of May 31, 2016, up to $2,878,197 in shares of NTIC common stock remained available for repurchase under NTIC&#8217;s
stock repurchase program.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC does not have any relationships with unconsolidated entities or financial partnerships,
such as entities often referred to as structured finance or special purpose entities, which would have been established for the

<p style="font-size: 10pt; margin: 0pt 0">NTIC is exposed to some market risk stemming from changes in foreign currency exchange
rates, commodity prices and interest rates.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Because the functional currency of NTIC&#8217;s foreign operations and investments in
its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from
transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro, the Japanese yen,
Indian Rupee, Chinese Renminbi, Korean won and the English pound against the U.S. dollar. NTIC&#8217;s fees for services provided
to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and thus fluctuations in
foreign currency exchange rates could result in declines in NTIC&#8217;s reported net income. Since NTIC&#8217;s investments in
its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would be reflected
as a foreign currency translation adjustment and would not change NTIC&#8217;s equity in income of joint ventures reflected in
its consolidated statements of income. NTIC does not hedge against its foreign currency exchange rate risk.</p>

of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest
period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate, and thus may subject
NTIC to some market risk on interest rates. As of May 31, 2016, NTIC had no borrowings under the line of credit.</p>

statement that speaks only as of the date made and to recognize that forward-looking statements are predictions of future results,
which may not occur as anticipated. Actual results could differ materially from those anticipated in the forward-looking statements

reasonable, NTIC does not know whether its expectations will prove correct. NTIC&#8217;s expectations reflected in its forward-looking

rates, commodity prices and interest rates.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Because the functional currency of NTIC&#8217;s foreign operations and investments in
its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from
transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro, the Japanese yen,
Indian Rupee, Chinese Renminbi, Korean won and the English pound against the U.S. dollar. NTIC&#8217;s fees for services provided
to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and thus fluctuations in
foreign currency exchange rates could result in declines in NTIC&#8217;s reported net income. Since NTIC&#8217;s investments in
its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would be reflected
as a foreign currency translation adjustment and would not change NTIC&#8217;s equity in income of joint ventures reflected in
its consolidated statements of income. NTIC does not hedge against its foreign currency exchange rate risk.</p>

<p style="font-size: 10pt; margin: 0pt 0">On March 23, 2015, NTIC and NTI Asean LLC, a majority-owned subsidiary of NTIC, filed
a lawsuit in Tianjin No 1 Intermediate People&#8217;s Court against two individuals, Meng Tao and Xu Hui, related to breaches of
duties and contractual commitments owed to NTI Asean under certain agreements related to NTIC&#8217;s former joint venture in China,
Tianjin Zerust Anti-Corrosion Technologies Ltd. The lawsuit alleges, among other things, that Mr. Meng Tao and Xu Hui have engaged
in self-dealing, usurped business opportunities, and received economic benefits that were required to go to Tianjin Zerust. At
this point it is too early in the lawsuit to reasonably estimate the amount of any recovery to NTI Asean.</p>

initiated a lawsuit in the District Court for the Second Judicial District, County of Ramsey, State of Minnesota against Cortec
Corporation alleging, among other things, that Cortec Corporation aided and abetted breaches of duties and contractual commitments
owed to the Company and NTI Asean related to NTIC&#8217;s joint venture in China, Tianjin Zerust. On November 4, 2015, NTIC and
NTI Asean were permitted to file an amended complaint adding new counts, including, but not limited to, one for breach of contract,
arising out of Cortec&#8217;s breach of a 2005 Settlement Agreement and Consent Order. The case was subsequently assigned to the
complex civil jury trial calendar, extending deadlines for discovery and trial. The current discovery deadline is September 23,
2016 and the trial will be scheduled during the March 27-April 14, 2017 jury trial block in Ramsey County. The parties attended
a court ordered mediation on September 24, 2015 which did not result in a settlement. A second mediation deadline of August 12,
2016 was set by the court in the amended scheduling order.</font></p>

For fiscal 2016 as in past years, the total amount available under the bonus plan for all plan participants, including executive officers, is dependent upon the Company&amp;#x2019;s earnings before interest, taxes and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted EBITOI). Each plan participant&amp;#x2019;s percentage of the overall bonus pool is based upon the number of plan participants, the individual&amp;#x2019;s annual base salary and the individual&amp;#x2019;s position and level of responsibility within the company. In the case of each of the Company&amp;#x2019;s executive officer participants, 75% of the amount of their individual bonus payout will be determined based upon the Company&amp;#x2019;s actual Adjusted EBITOI for fiscal 2016 compared to a pre-established target Adjusted EBITOI for fiscal 2016 and 25% of the payout will be determined based upon such executive officer&amp;#x2019;s achievement of certain pre-established individual performance objectives. The payment of bonuses under the plan are discretionary and may be paid to executive officer participants in both cash and shares of the Company&amp;#x2019;s common stock, the exact amount and percentages will be determined by the Company&amp;#x2019;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&amp;#x2019;s consolidated financial statements for fiscal 2016. There was $215,000 accrued for management bonuses for the nine months ended May 31, 2016 compared to an accrual of $466,000 for management bonuses for the nine months ended May 31, 2015.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Four joint ventures (consisting of the Company&amp;#x2019;s joint ventures in Korea, India, Thailand and Tianjin Zerust) accounted for 65.6% of the Company&amp;#x2019;s trade joint venture receivables at May 31, 2016 and accounted for 67.0% of the Company&amp;#x2019;s trade joint venture receivables at August 31, 2015.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 17; Value: 1 --&gt;   &lt;!-- Field: /Page --&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;On March 23, 2015, the Company and NTI Asean filed a lawsuit in Tianjin No 1 Intermediate People&amp;#x2019;s Court against two individuals, Meng Tao and Xu Hui, related to breaches of duties and contractual commitments owed to NTI Asean under certain agreements related to the Company&amp;#x2019;s former joint venture in China, Tianjin Zerust Anti-Corrosion Technologies Ltd. The lawsuit alleges, among other things, that Mr. Meng Tao and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required to go to Tianjin Zerust. As of May 31, 2016, the Company is not able to reasonably estimate the amount of any recovery to NTI Asean, if any.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;On April 21, 2015, the Company and NTI Asean initiated a lawsuit in the District Court for the Second Judicial District, County of Ramsey, State of Minnesota against Cortec Corporation alleging, among other things, that Cortec Corporation aided and abetted breaches of duties and contractual commitments owed to the Company and NTI Asean related to the Company&amp;#x2019;s joint venture in China, Tianjin Zerust.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;From time to time, the Company is subject to various other claims and legal actions in the ordinary course of its business. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, where the Company has assessed that a loss is probable and an amount could be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that material loss may be have been incurred. In the opinion of management, as of May 31, 2016, the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the Company&amp;#x2019;s consolidated results of operations, financial position or cash flows.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

No amounts were outstanding under the line of credit as of both May 31, 2016 and August 31, 2015. At the option of the Company, outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by the Company or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate. Interest is payable in arrears (a) for the portion of advances bearing interest under the prime rate on the last day of each month during the term thereof and (b) for the portion of advances bearing interest under the LIBOR option on the last day of the respective LIBOR interest period selected for such advance. Any unpaid interest is payable on the maturity date.

The loan agreement contains standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations and other matters customarily restricted in such agreements. Under the loan agreement, the Company is subject to a minimum fixed charge coverage ratio of 1.10:1.00.

This guidance, which includes additional disclosure requirements regarding revenue, cash flows and obligations related to contracts with customers, was originally to be effective for the Company beginning in fiscal year 2018. In July 2015, the FASB confirmed a one-year deferral of the effective date of the new revenue standard which also allows early adoption as of the original effective date. The updated guidance will be effective for the Company&amp;#x2019;s first quarter of 2019. The Company is currently evaluating the impact of adopting ASU 2014-09 on its consolidated financial statements, but believes there will be no material impact, if any.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In July 2015, the FASB issued ASU No. 2015-11, &amp;#x201c;&lt;div style="display: inline; font-style: italic;"&gt;Inventory&lt;/div&gt;&amp;#x201d;, which modifies the subsequent measurement of inventories recorded under a first-in-first-out or average cost method. Under the new standard, such inventories are required to be measured at the lower of cost and net realizable value. The new standard is effective for the Company&amp;#x2019;s fiscal year 2018, with prospective application. The Company does not expect the adoption of the provisions of ASU 2015-11 to have a material impact on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In November&amp;nbsp;2015, FASB issued ASU 2015-17,&amp;nbsp;&lt;div style="display: inline; font-style: italic;"&gt;Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes&lt;/div&gt;&amp;nbsp;which requires that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet. The amendment takes effect for public entities for fiscal years beginning after December&amp;nbsp;15, 2017, with early adoption available. The Company is currently assessing the impact that ASU 2015-17 will have on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;During February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, &amp;#x201c;&lt;div style="display: inline; font-style: italic;"&gt;Leases&lt;/div&gt;.&amp;#x201d; ASU No. 2016-02 was issued to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company is currently assessing the effect that ASU No. 2016-02 will have on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 8; Value: 1 --&gt;   &lt;!-- Field: /Page --&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In March 2016, the FASB issued ASU No. 2016-07, &amp;#x201c;&lt;div style="display: inline; font-style: italic;"&gt;Investments &amp;#x2013; Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting&lt;/div&gt;.&amp;#x201d; Among other things, the amendments in ASU 2016-07 eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor&amp;#x2019;s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The Company is currently assessing the impact that ASU 2016-07 will have on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In March 2016, the FASB issued ASU 2016-09, &lt;div style="display: inline; font-style: italic;"&gt;Stock Compensation&lt;/div&gt;, which is intended to simplify several aspects of the accounting for share-based payment award transactions. The guidance will be effective for the fiscal year beginning after December 15, 2016, including interim periods within that year. The Company is in the process of evaluating the impacts of the adoption of this ASU.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Although there are several other new accounting pronouncements issued or proposed by the FASB, which the Company has adopted or will adopt, as applicable, the Company does not believe any of these accounting pronouncements has had or will have a material impact on the Company&amp;#x2019;s consolidated financial position or operating results.&lt;/div&gt;&lt;/div&gt;</us-gaap:DescriptionOfNewAccountingPronouncementsNotYetAdopted>

The Compensation Committee of the Board of Directors and the Board of Directors administer these plans.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The 2007 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, stock unit awards, performance awards and stock bonuses to eligible recipients to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities for equity participation in the Company, and to reward those individuals who contribute to the achievement of the Company&amp;#x2019;s economic objectives. Subject to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company&amp;#x2019;s common stock are issuable under the 2007 Plan. Options granted under the 2007 Plan generally have a term of ten years and become exercisable over a three- or four-year period beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market value of the Company&amp;#x2019;s common stock on the date of grant. The Company issues new shares upon the exercise of options. As of May 31, 2016, only stock options and stock bonuses had been granted under the 2007 Plan.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The maximum number of shares of common stock of the Company available for issuance under the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting purposes. The Company issued 2,439 and 1,948 shares on September 1, 2015 and 2014, respectively, under the ESPP. The Company issued 3,144 shares on March 1, 2016 under the ESPP.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company granted options to purchase an aggregate of 53,447 and 45,067 shares of its common stock during the nine months ended May 31, 2016 and 2015, respectively. The fair value of option grants is determined at date of grant, using the Black-Scholes option pricing model with the assumptions listed below.&amp;nbsp; The Company recognized compensation expense of $325,576 and $378,421 during the nine months ended May 31, 2016 and 2015, respectively, related to the options that vested during such time period. As of May 31, 2016, the total compensation cost for nonvested options not yet recognized in the Company&amp;#x2019;s consolidated statements of operations was $341,261, net of estimated forfeitures. Stock-based compensation expense of $101,861 is expected through the remainder of fiscal year 2016, and $159,600 and $79,800 is expected to be recognized during fiscal 2017 and fiscal 2018, respectively, based on outstanding options as of May 31, 2016. Future option grants will impact the compensation expense recognized. Stock-based compensation expense is included in general and administrative expense on the consolidated statements of operations.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company currently estimates a ten percent forfeiture rate for stock options and continually reviews this estimate for future periods.&lt;/div&gt;

No such adjustments were recorded during the nine months ended May 31, 2016.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 11; Value: 1 --&gt;   &lt;!-- Field: /Page --&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Because of the lack of financial and other information received from Tianjin Zerust, it is possible that receipt of future financial and other information from Tianjin Zerust may impact the realization of the Company&amp;#x2019;s investment in and realization of a receivable from Tianjin Zerust.

This guidance, which includes additional disclosure requirements regarding revenue, cash flows and obligations related to contracts with customers, was originally to be effective for the Company beginning in fiscal year 2018. In July 2015, the FASB confirmed a one-year deferral of the effective date of the new revenue standard which also allows early adoption as of the original effective date. The updated guidance will be effective for the Company&#x2019;s first quarter of 2019.

Under the new standard, such inventories are required to be measured at the lower of cost and net realizable value. The new standard is effective for the Company&#x2019;s fiscal year 2018, with prospective application. The Company does not expect the adoption of the provisions of ASU 2015-11 to have a material impact on its consolidated financial statements.</div> <div style=" font-size: 10pt; margin: 0pt 0">In November&nbsp;2015, FASB issued ASU 2015-17,&nbsp;<div style="display: inline; font-style: italic;">Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes</div>&nbsp;which requires that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet. The amendment takes effect for public entities for fiscal years beginning after December&nbsp;15, 2017, with early adoption available.

ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption.

The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor&#x2019;s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted.

Subject to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company&#x2019;s common stock are issuable under the 2007 Plan. Options granted under the 2007 Plan generally have a term of ten years and become exercisable over a three- or four-year period beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market value of the Company&#x2019;s common stock on the date of grant. The Company issues new shares upon the exercise of options. As of May 31, 2016, only stock options and stock bonuses had been granted under the 2007 Plan.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The maximum number of shares of common stock of the Company available for issuance under the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting purposes. The Company issued 2,439 and 1,948 shares on September 1, 2015 and 2014, respectively, under the ESPP.

As of May 31, 2016, the total compensation cost for nonvested options not yet recognized in the Company&#x2019;s consolidated statements of operations was $341,261, net of estimated forfeitures. Stock-based compensation expense of $101,861 is expected through the remainder of fiscal year 2016, and $159,600 and $79,800 is expected to be recognized during fiscal 2017 and fiscal 2018, respectively, based on outstanding options as of May 31, 2016.

For fiscal 2016 as in past years, the total amount available under the bonus plan for all plan participants, including executive officers, is dependent upon the Company&#x2019;s earnings before interest, taxes and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted EBITOI). Each plan participant&#x2019;s percentage of the overall bonus pool is based upon the number of plan participants, the individual&#x2019;s annual base salary and the individual&#x2019;s position and level of responsibility within the company. In the case of each of the Company&#x2019;s executive officer participants, 75% of the amount of their individual bonus payout will be determined based upon the Company&#x2019;s actual Adjusted EBITOI for fiscal 2016 compared to a pre-established target Adjusted EBITOI for fiscal 2016 and 25% of the payout will be determined based upon such executive officer&#x2019;s achievement of certain pre-established individual performance objectives. The payment of bonuses under the plan are discretionary and may be paid to executive officer participants in both cash and shares of the Company&#x2019;s common stock, the exact amount and percentages will be determined by the Company&#x2019;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&#x2019;s consolidated financial statements for fiscal 2016.

The lawsuit alleges, among other things, that Mr. Meng Tao and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required to go to Tianjin Zerust.

The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, where the Company has assessed that a loss is probable and an amount could be reasonably estimated.

The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that material loss may be have been incurred. In the opinion of management, as of May 31, 2016, the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the Company&#x2019;s consolidated results of operations, financial position or cash flows.</div></div><span></span>

Because the fair value of cost-method investments is not readily determinable, the evaluation of whether an investment is impaired generally consists of whether an event or change in circumstances has occurred during the reporting period that may have a significant adverse effect on the fair value of the investment (an "impairment indicator").  Impairment indicators include, but are not limited to: (1) significant deterioration in the earnings performance, credit rating, asset quality, or business prospects of the investee; (2) significant adverse change in the regulatory, economic, or technological environment of the investee; (3) significant adverse change in the general market condition of either the geographic area or the industry in which the investee operates; (4) a bona fide offer to purchase (whether solicited or unsolicited), an offer by the investee to sell, or a completed auction process for the same or similar security for an amount less than the cost of the investment; or (5) factors that raise significant concerns about the investee's ability to continue as a going concern, such as negative cash flows from operations, working capital deficiencies, or noncompliance with statutory capital requirements or debt covenants.</p></div>
