<p style="font-size: 10pt; margin: 0pt 0">In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards
Update (ASU) No. 2016-02, <i>Leases</i>. The guidance in ASU 2016-02 supersedes the lease recognition requirements in the Accounting
Standards Codification Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease
for both financing and operating leases, along with additional qualitative and quantitative disclosures. This standard became effective
for the Company on September 1, 2019.</p>

<p style="font-size: 10pt; margin: 0pt 0">The FASB has subsequently issued the following amendments to ASU 2016-02, which have

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

<p style="font-size: 10pt; margin: 0pt 0">The Company adopted the new leasing standards on September 1, 2019, using a modified
retrospective transition approach to be applied to leases existing as of, or entered into after, September 1, 2019; and, consequently,
financial information will not be updated and the disclosures required under Topic 842 will not be provided for dates and periods
prior to September 1, 2019. The Company has reviewed its existing lease contracts and the impact of the new leasing standards on
its consolidated results of operations, financial position and disclosures. Upon adoption of the new leasing standards, the Company
recognized a lease liability and related right-of-use asset on our consolidated balance sheet of approximately $600,000.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">In February 2018, the FASB issued ASU No. 2018-02, <i>Income Statement &#8211; Reporting
Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income</i>, which
will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from
the Tax Cuts and Jobs Act (Tax Reform Act) that are stranded in accumulated other comprehensive income. This standard also requires
certain disclosures about stranded tax effects. ASU No. 2018-02, however, does not change the underlying guidance that requires
that the effect of a change in tax laws or rates be included in income from continuing operations. ASU No. 2018-02 will become
effective for the Company&#8217;s fiscal year 2020, with the option for early adoption at any time prior to the effective date.
It must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the
U.S. federal corporate income tax rate in the Tax Reform Act is recognized. The Company is currently assessing the impact this

<p style="font-size: 10pt; margin: 0pt 0">The Company has three stock-based compensation plans under which stock options or other
stock-based awards have been granted: the Northern Technologies International Corporation 2019 Stock Incentive Plan (the 2019 Plan),
which was approved by stockholders at the 2019 annual meeting of stockholders, the Northern Technologies International Corporation
Amended and Restated 2007 Stock Incentive Plan (the 2007 Plan) and the Northern Technologies International Corporation Employee
Stock Purchase Plan (the ESPP). The 2019 Plan replaced the 2007 Plan with respect to future grants; and, therefore, no further
awards may be made under the 2007 Plan. 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 2019 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 2019 Plan, up to a maximum of 800,000 shares of the Company&#8217;s common stock are issuable
under the 2019 Plan. Options granted generally have a term of ten years and become exercisable over a one- or three- 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 November 30, 2019, options to purchase an aggregate of 300,770 shares of the Company&#8217;s common stock had been granted under
the 2019 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 200,000 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. As of November 30, 2019, 87,447 shares of common stock remained available for sale under the ESPP.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">The Company granted options to purchase an aggregate of 300,770 and 141,768 shares of
its common stock during the three months ended November 30, 2019 and 2018, 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. The Company recognized compensation
expense of $318,818 and $357,980 during the three months ended November 30, 2019 and 2018, respectively, related to the options
that vested during such time period. As of November 30, 2019, the total compensation cost for non-vested options not yet recognized
in the Company&#8217;s consolidated statements of operations was $1,018,956. Stock-based compensation expense of $1,018,956 is
expected through the remainder of fiscal year 2020, and $20,834 is expected to be recognized during fiscal 2021, based on outstanding
options as of November 30, 2019. 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>

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

<p style="font-size: 10pt; margin: 0pt 0">The Company currently has 19 operating leases for various buildings, equipment and vehicles.
These leases are under non-cancelable operating lease agreements with expiration dates between December 31, 2019 and June 30, 2024.
The Company has the option to extend certain leases to five or ten-year term(s), and has the right of first refusal on any sale.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">The Company records lease liabilities within current liabilities or long-term liabilities
based upon the length of time associated with the lease payments. The Company records its long-term operating leases as right-of-use
assets. Upon initial adoption, using the modified retrospective transition approach, no leases with terms less than 12-months have
been capitalized to the balance sheet consistent with ASC 842. Instead, these leases are recognized in the Consolidated Statement
of Operations on a straight-line expense throughout the lives of the leases. All leases of the Company do not contain common area
maintenance or security agreements.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">The Company has made certain assumptions and judgments when applying ASC 842, the most
significant of which is that the Company elected the package of practical expedients available for transition which allow the Company
to not reassess whether expired or existing contracts contain leases under the new definition of a lease, lease classification
for expired or existing leases and whether previously capitalized initial direct costs would qualify for capitalization under ASC
842. Additionally, the Company did not elect to use hindsight when considering judgments and estimates such as assessments of lessee
options to extend or terminate a lease or purchase the underlying asset. The Company has no contingent rent agreements.</p>

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

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

<p style="font-size: 10pt; margin: 0pt 0">On August 31, 2019, the Compensation Committee of the Board of Directors of the Company
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, 2020. For fiscal 2020 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 EBITOI for fiscal 2020 compared to a pre-established target EBITOI for fiscal
2020, 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 bonuses may be paid to executive
officer participants in both cash and shares of NTIC common stock, with the exact amount and percentages 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 2020. There was $400,000 accrued for management bonuses for the three months ended November 30,
2019 compared to $450,000 accrued for management bonuses for the three months ended November 30, 2018.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">Three joint ventures (consisting of the Company&#8217;s joint ventures in South Korea,
Thailand and India) accounted for 51.4% of the Company&#8217;s trade joint venture receivables at November 30, 2019 and five joint
ventures (consisting of the Company&#8217;s joint ventures in South Korea, Thailand, France, Germany and India) accounted for 69.6%
of the Company&#8217;s trade joint venture receivables as of August 31, 2019.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">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 have been incurred. In the opinion of management, as of November 30, 2019,
the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the
Company&#8217;s consolidated results of operations, financial position or cash flows.</p></div><p style="font-size: 10pt; margin: 0pt 0"></p>

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

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</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<sup>&#174;</sup> brand. NTIC has been selling its proprietary
ZERUST<sup>&#174;</sup> 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 bio-based and certified compostable (fully biodegradable) polymer resin compounds and finished products under
the Natur-Tec<sup>&#174;</sup> 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<sup>&#174;</sup> rust and corrosion inhibiting products include plastic
and paper packaging, liquids, coatings, rust removers, cleaners, and diffusers as well as 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<sup>&#174;</sup> rust and corrosion
inhibiting products to analyze their specific needs and develop systems to meet their performance requirements. In North America,
NTIC sells its ZERUST<sup>&#174;</sup> corrosion prevention solutions through a network of independent distributors and agents supported
by a direct sales force. Internationally, NTIC sells its ZERUST<sup>&#174;</sup> 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, NTI Asean LLC (NTI Asean), certain other
wholly-owned or majority-owned subsidiaries, and joint venture arrangements in North America, Europe and Asia. NTIC also sells
products directly to its joint venture partners through its wholly-owned subsidiary in Germany, NTIC Europe GmbH (NTI Europe).</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<sup>&#174;</sup> corrosion prevention technologies. Consequently, for the past several years, NTIC has focused significant
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<sup>&#174;</sup> 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 leaks caused by corrosion.</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<sup>&#174;</sup> 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<sup>&#174;</sup> corrosion prevention solutions to customers in
the oil and gas industry typically involves long sales cycles, often including multi-year trial periods with each customer and
a slow integration process thereafter.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">Natur-Tec<sup>&#174;</sup> biobased and compostable plastics are manufactured using NTIC&#8217;s
patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec<sup>&#174;</sup>
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 resin compounds are certified to be 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 and coated paper products. In North America, NTIC markets its Natur-Tec<sup>&#174;</sup>
resin compounds 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<sup>&#174;</sup> bioplastic products.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC receives funds from its joint ventures as fees for services that NTIC provides to
its joint ventures and as dividend distributions. 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 each joint
venture based on the overall profitability of the joint venture. Such profitability is subject to variability from quarter to quarter,
which, in turn, subjects NTIC&#8217;s earnings to variability from quarter to quarter. The profits of each joint venture 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>

<p style="font-size: 10pt; margin: 0pt 0">NTIC accounts for the investments and financial results of its joint ventures in its

<p style="font-size: 10pt; margin: 0pt 0">NTIC considers EXCOR to be individually significant to NTIC&#8217;s consolidated assets

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s management, including its chief executive officer, who is NTIC&#8217;s chief
operating decision maker, reports and manages NTIC&#8217;s operations in two reportable business segments based on products sold,
customer base and distribution center: ZERUST<sup>&#174;</sup> products and services and Natur-Tec<sup>&#174;</sup> products. All
share and per share data have been adjusted for all periods presented to reflect the two-for-one stock split effective June 28,

<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 3.8% during the three months ended November
30, 2019 compared to the three months ended November 30, 2018. This increase was primarily a result of an increase in sales of
Natur-Tec<sup>&#174;</sup> products.</p>

<p style="font-size: 10pt; margin: 0pt 0">During the three months ended November 30, 2019, 68.0% of NTIC&#8217;s consolidated net
sales were derived from sales of ZERUST<sup>&#174;</sup> products and services, which decreased 1.1% to $9,949,512 compared to $10,065,174
for the three months ended November 30, 2018. This decrease was due to lower sales from existing customers for products as a result
of decreased demand. NTIC has focused its sales efforts of ZERUST<sup>&#174;</sup> 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 three months ended November 30, 2019 included $520,844
of sales made to customers in the oil and gas industry compared to $986,173 for the three months ended November 30, 2018. Overall
demand for ZERUST<sup>&#174;</sup> 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.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">During the three months ended November 30, 2019, 32.0% of NTIC&#8217;s consolidated net
sales were derived from sales of Natur-Tec<sup>&#174;</sup> products compared to 28.6% during the three months ended November 30,
2018. Net sales of Natur-Tec<sup>&#174;</sup> products increased 16.2% during the three months ended November 30, 2019 compared
to the three months ended November 30, 2018 primarily due to an increase in finished product sales in North America and finished
product sales at NTIC&#8217;s majority-owned subsidiary in India.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">Cost of goods sold as a percentage of net sales decreased slightly to 67.0% during the
three months ended November 30, 2019 compared to 67.1% during the three months ended November 30, 2018.</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 from joint ventures decreased 35.4% to $1,293,990 during
the three months ended November 30, 2019 compared to $2,004,162 during the three months ended November 30, 2018. This decrease
was primarily due to a corresponding decrease in net sales at the joint ventures, which decreased 16.5% to $25,460,294 during the
three months ended November 30, 2019 compared to $30,479,926 for the three months ended November 30, 2018. The decrease in the
net sales of NTIC&#8217;s joint ventures was due primarily to decreased sales from existing customers for existing products as
a result of decreased demand. The decrease in net sales of NTIC&#8217;s joint ventures 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 decreased 4.5% to $5,898,620 during the three months
ended November 30, 2019 compared to $6,179,048 for the three months ended November 30, 2018. This decrease was primarily due to
a decrease in NTIC&#8217;s personnel expenses and achievement of various cost control actions undertaken by management.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">NTIC spent $961,641 and $872,157 during the three months ended November 30, 2019 and
2018, respectively, in connection with its research and development activities. NTIC anticipates that it will spend between $3,600,000
and $3,900,000 in fiscal 2020 on research and development activities.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">Net income attributable to NTIC decreased $284,509 to $1,212,550, or $0.13 per diluted
common share, for the three months ended November 30, 2019 compared to $1,497,059, or $0.16 per diluted common share, for the three
months ended November 30, 2018. This decrease was primarily the result of the decrease in joint venture operations during the three
months ended November 30, 2019 compared to the three months ended November 30, 2018.</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 or loss will continue to be subject to
significant volatility primarily due to the financial performance of its subsidiaries and joint ventures, sales of its ZERUST<sup>&#174;</sup>
products and services into the oil and gas industry, and sales of its Natur-Tec<sup>&#174;</sup> bioplastics products, which sales
fluctuate more on a quarterly basis than the traditional ZERUST<sup>&#174;</sup> business.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s working capital, defined as current assets less current liabilities, was
$25,253,374 at November 30, 2019, including $4,106,796 in cash and cash equivalents and $2,987,095 in available for sale securities,
compared to $25,460,569 at August 31, 2019, including $5,856,758 in cash and cash equivalents and $3,565,258 in available for sale
securities.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">On October 22, 2019, the Company&#8217;s Board of Directors announced a quarterly cash
dividend of $0.065 per share of NTIC&#8217;s common stock, payable on November 20, 2019 to stockholders of record on November 6,
2019. During fiscal 2019, the Company&#8217;s Board of Directors declared four quarterly cash dividends of $0.06 per share each.
Although NTIC&#8217;s Board of Directors intends to continue to declare regular quarterly cash dividends, the declaration of future
dividends is not guaranteed and will be determined by NTIC&#8217;s Board of Directors in light of conditions then existing, including
NTIC&#8217;s net income, financial condition, cash requirements, restrictions in financing agreements, business conditions and
other factors.</p>

<p style="font-size: 10pt; margin: 0pt 0">During the three months ended November 30, 2019, 68.0% of NTIC&#8217;s consolidated net
sales were derived from sales of ZERUST<sup>&#174;</sup> products and services, which decreased 1.1% to $9,949,512 during the three
months ended November 30, 2019 compared to $10,065,174 during the three months ended November 30, 2018. This decrease was primarily
the result of decreased ZERUST<sup>&#174; </sup>oil and gas net sales due to decreased demand. 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,

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s net sales to the oil and gas industry sector decreased during the three
months ended November 30, 2019 compared to the prior fiscal year period, primarily due to decreased demand for ZERUST<sup>&#174;
</sup>oil and gas products and services. NTIC anticipates that its sales of ZERUST<sup>&#174;</sup> 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,
specifically due to the volatility of oil prices. Demand for oil and gas 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 oil and gas products, the timing of one or more orders can materially affect NTIC&#8217;s
quarterly sales compared to prior fiscal year quarters.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">During the three months ended November 30, 2019, 32.0% of NTIC&#8217;s consolidated net
sales were derived from sales of Natur-Tec<sup>&#174;</sup> products, which increased 16.2% to $4,681,888 during the three months
ended November 30, 2019 compared to the three months ended November 30, 2018. This increase was primarily due to an increase in
finished product sales in North America and finished product sales at NTIC&#8217;s majority-owned subsidiary in India.</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 3.6% for the three months ended
November 30, 2019 compared to the three months ended November 30, 2018. Cost of goods sold as a percentage of net sales decreased
slightly to 67.0% for the three months ended November 30, 2019 compared to 67.1% for the three months ended November 30, 2018.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Equity in Income from Joint Ventures.</i> NTIC&#8217;s equity in income from joint
ventures decreased 35.4% to $1,293,990 during the three months ended November 30, 2019 compared to $2,004,162 during the three
months ended November 30, 2018. This decrease was primarily a result of changing profitability of the joint ventures, which fluctuates
based on net sales, during the respective periods. Of the total equity in income from joint ventures, NTIC had equity in income
from joint ventures of $821,164 attributable to EXCOR during the three months ended November 30, 2019 compared to $1,519,901 during
the three months ended November 30, 2018.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Fees for Services Provided to Joint Ventures</i>. NTIC recognized fee income for services
provided to joint ventures of $1,358,325 during the three months ended November 30, 2019 compared to $1,428,435 during the three
months ended November 30, 2018, representing a decrease of $70,110, or 4.9%. Fee income for services provided to joint ventures
is traditionally a function of the sales made by NTIC&#8217;s joint ventures. Total net sales of NTIC&#8217;s joint ventures decreased
16.5% to $25,460,294 during the three months ended November 30, 2019 compared to $30,479,926 for the three months ended November
30, 2018. Net sales of NTIC&#8217;s joint ventures are not included in NTIC&#8217;s consolidated financial statements. Of the total
fee income for services provided to joint ventures, fees of $212,101 were attributable to EXCOR during the three months ended November
30, 2019 compared to $214,992 attributable to EXCOR during the three months ended November 30, 2018.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Selling Expenses</i>. NTIC&#8217;s selling expenses increased 2.7% for the three months
ended November 30, 2019 compared to the same period in fiscal 2019 due primarily to increases in operating expenses associated
with ZERUST<sup>&#174;</sup> sales efforts, consisting primarily of selling and personnel expenses. Selling expenses as a percentage
of net sales decreased slightly to 19.7% for the three months ended November 30, 2019 from 19.9% during the three months ended
November 30, 2018 primarily due to the decrease in net sales, as previously described.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>General and Administrative Expenses</i>. NTIC&#8217;s general and administrative expenses
decreased 17.9% for the three months ended November 30, 2019 compared to the same period in fiscal 2019 primarily due to decreased
personnel costs and the implementation of various cost control initiatives. As a percentage of net sales, general and administrative
expenses decreased to 14.0% for the three months ended November&nbsp;30, 2019 from 17.7% for the three months ended November 30,
2018 due primarily to the decreases in expenses in North America and NTIC&#8217;s subsidiary in India, and the slight increase
in net sales, as previously described.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Research and Development Expenses</i>. NTIC&#8217;s research and development expenses
increased 10.3% for the three months ended November 30, 2019 compared to the same period in fiscal 2019 primarily due to increases
in research and development efforts.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Interest Income</i>. NTIC&#8217;s interest income increased to $49,038 during the
three months ended November 30, 2019 compared to $12,787 during the three months ended November 30, 2018 due to changing levels
of invested cash.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Interest Expense</i>. NTIC&#8217;s interest expense increased to $5,444 during the
three months ended November&nbsp;30, 2019 compared to $2,357 during the three months ended November 30, 2018.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Income Before Income Tax Expense</i>. NTIC incurred income before income tax expense
equal to $1,623,605 for the three months ended November 30, 2019 compared to $1,896,894 for the three months ended November 30,
2018.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Income Tax Expense</i>. Income tax expense was $264,066 during the three months ended
November 30, 2019 compared to $255,703 during the three months ended November 30, 2018. Income tax expense was calculated based
on management&#8217;s estimate of NTIC&#8217;s annual effective income tax rate.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</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
future domestic cash needs. As a result, U.S. income and foreign withholding taxes have not been recognized on the cumulative undistributed
earnings of $23,373,721 and $22,178,126 at November 30, 2019 and August 31, 2019, 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">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Net Income Attributable to NTIC</i>. Net income attributable to NTIC decreased $284,509
to $1,212,550, or $0.13 per diluted common share, for the three months ended November 30, 2019 compared to $1,497,059, or $0.16
per diluted common share, for the three months ended November 30, 2018. This decrease was primarily the result of the decrease
in operating expenses and decrease in joint venture operations during the three months ended November 30, 2019 compared to the
prior year period, partially offset by the increase in gross profit.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Other Comprehensive Income - Foreign Currency Translations Adjustment. </i>The changes
in the foreign currency translations adjustment were due to the fluctuations of the U.S. dollar compared to the Euro and other
foreign currencies during the three months ended November 30, 2019 compared to the same period in fiscal 2019.</p>

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

<p style="font-size: 10pt; margin: 0pt 0"><i>Sources of Cash and Working Capital</i>. NTIC&#8217;s working capital, defined as
current assets less current liabilities, was $25,253,374 at November 30, 2019, including $4,106,796 in cash and cash equivalents
and $2,987,095 in available for sale securities, compared to $25,460,569 at August 31, 2019, including $5,856,758 in cash and cash
equivalents and $3,565,258 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 November 30, 2019, NTIC had a revolving line of credit with PNC Bank of $3,000,000
with no amounts outstanding. 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. On December 16, 2019, the Company and PNC Bank extended the
maturity date of the line of credit from January 7, 2020 to January 7, 2021. 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">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. Any lines of credit issued by PNC Bank would
decrease the availability under the revolving line of credit.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">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 November 30, 2019, NTIC was in compliance with all debt covenants.</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, available
for sale securities, 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, cash dividends and any stock repurchases for at least the next 12 months. During the remainder of fiscal 2020,
NTIC expects to continue to invest directly and through its use of working capital in NTIC China, Zerust Mexico, NTI Europe, research
and development, marketing efforts, resources for the application of its corrosion prevention technology in the oil and gas industry,
and its Natur-Tec<sup>&#174;</sup> bio-plastics business, although the amounts of these various investments are not known at this
time. 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 from joint ventures 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 there is limited exposure 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 Flow</i>. Net cash used in operating activities during the three
months ended November&nbsp;30, 2019 was $1,567,156, which resulted principally from NTIC&#8217;s equity in income from joint ventures,
an increase in inventory and increases in trade receivables excluding joint ventures, and income tax payable, partially offset
by NTIC&#8217;s net income, depreciation and amortization and an increase in accounts payable and accrued liabilities. Net cash
used in operating activities during the three months ended November 30, 2018 was $738,606, which resulted principally from NTIC&#8217;s
equity in income from joint ventures, an increase in inventory and increases in trade receivables excluding joint ventures, and
income tax payable, partially offset by NTIC&#8217;s net income, depreciation and amortization and an increase in accounts payable
and accrued liabilities.</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. 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 30 days and 90 days for trade
receivables from its joint ventures. 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 receivable in excess of the provided allowance
are determined uncollectible, they are charged to selling expense in the period that the 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">NTIC experienced an increase in trade receivables and inventory as of November 30, 2019
compared to August 31, 2019. Trade receivables excluding joint ventures as of November&nbsp;30, 2019 increased $581,248 compared
to August 31, 2019, primarily related to the timing of collections and the increase in sales.</p>

<p style="font-size: 10pt; margin: 0pt 0">Outstanding trade receivables excluding joint ventures balances as of November 30, 2019

<p style="font-size: 10pt; margin: 0pt 0">Outstanding trade receivables from joint ventures as of November 30, 2019 decreased $182,798
compared to August 31, 2019 primarily due to the timing of payments. Outstanding balances from trade receivables from joint ventures
decreased an average of 15 days from an average of 115 days from balances outstanding from these customers compared to August 31,
2019. The average days outstanding of trade receivables from joint ventures as of November 30, 2019 were primarily due to the receivables
balances at NTIC&#8217;s joint ventures in South Korea, India and Thailand.</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 November 30, 2019

<p style="font-size: 10pt; margin: 0pt 0">Net cash provided by investing activities for the three months ended November 30, 2019

additions to property and equipment and additions to patents. Net cash used in investing activities for the three months ended
November 30, 2018 was $1,463,950, which was primarily the result of cash provided by the sale of available for sale securities,

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.
No repurchases occurred during the three months ended November 30, 2019. As of November 30, 2019, up to $2,640,548 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"><i>Cash Dividends</i>. On October 22, 2019, NTIC&#8217;s Board of Directors declared
a cash dividend of $0.065 per share of NTIC&#8217;s common stock, payable on November 20, 2019 to stockholders of record on November
6, 2019. Although NTIC&#8217;s Board of Directors intends to continue to declare regular quarterly cash dividends, the declaration
of future dividends is not guaranteed and will be determined by NTIC&#8217;s Board of Directors in light of conditions then existing,
including NTIC&#8217;s net income, financial condition, cash requirements, restrictions in financing agreements, business conditions
and other factors.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Stock Split</i>. On June 3, 2019, NTIC&#8217;s Board of Directors declared a two-for-one
stock split of NTIC&#8217;s common stock effected in the form of a 100% share dividend distributed on June 28, 2019 to record holders
as of June 17, 2019. As a result of this action, approximately 4.5 million shares were issued to stockholders of record as of June
17, 2019. The par value of the common stock remains at $0.02 per share, and, accordingly, approximately $90,900 was transferred
from additional paid-in capital to common stock. Net income and dividends declared per share and weighted average shares outstanding
presented in this report reflect the 100 percent stock dividend. The two-for-one stock split is reflected in the share amounts

an aggregate of approximately $600,000 to $900,000 on capital expenditures during fiscal 2020, which it expects will relate primarily
to the purchase of new equipment.</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, established for the purpose of facilitating
off-balance sheet financial arrangements. As such, NTIC is not materially exposed to any financing, liquidity, market or credit
risk that could arise if NTIC had engaged in such arrangements.</p>

<p style="font-size: 10pt; margin: 0pt 0">Inflation in the United States and abroad historically has had little effect on NTIC.
Although NTIC&#8217;s business historically has not been seasonal, NTIC believes there is some seasonality in its business. NTIC
anticipates its net sales in the second fiscal quarter may be adversely affected by the long Chinese New Year, the North American
holiday season and overall less corrosion taking place at lower winter temperatures worldwide.</p>

<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,
the Indian Rupee, the Chinese Renminbi, the South 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 from joint ventures
reflected in its consolidated statements of operations. NTIC does not hedge against its foreign currency exchange rate risk.</p>

<p style="font-size: 10pt; margin: 0pt 0">At the option of NTIC, outstanding advances under NTIC&#8217;s $3,000,000 revolving line
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 November 30, 2019, NTIC had no borrowings under the line of credit.</p>

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,
the Indian Rupee, the Chinese Renminbi, the South 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 from joint ventures
reflected in its consolidated statements of operations. NTIC does not hedge against its foreign currency exchange rate risk.</p>

<p style="font-size: 10pt; margin: 0pt 0">At the option of NTIC, outstanding advances under NTIC&#8217;s $3,000,000 revolving line
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 November 30, 2019, NTIC had no borrowings under the line of credit.</p>

required to be disclosed by NTIC in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded,
processed, summarized and reported within the time periods specified in the Securities and Exchange Commission&#8217;s rules and

These leases are under non-cancelable operating lease agreements with expiration dates between &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2019 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2024. &lt;/div&gt;The Company has the option to extend certain leases to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt; or &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ten&lt;/div&gt;-year term(s), and has the right of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; refusal on any sale.&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 records lease liabilities within current liabilities or long-term liabilities based upon the length of time associated with the lease payments. The Company records its long-term operating leases as right-of-use assets. Upon initial adoption, using the modified retrospective transition approach, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; leases with terms less than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&lt;/div&gt;-months have been capitalized to the balance sheet consistent with ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842.&lt;/div&gt; Instead, these leases are recognized in the Consolidated Statement of Operations on a straight-line expense throughout the lives of the leases. All leases of the Company do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; contain common area maintenance or security agreements.&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 has made certain assumptions and judgments when applying ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842,&lt;/div&gt; the most significant of which is that the Company elected the package of practical expedients available for transition which allow the Company to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; reassess whether expired or existing contracts contain leases under the new definition of a lease, lease classification for expired or existing leases and whether previously capitalized initial direct costs would qualify for capitalization under ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842.&lt;/div&gt; Additionally, the Company did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; elect to use hindsight when considering judgments and estimates such as assessments of lessee options to extend or terminate a lease or purchase the underlying asset. The Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; contingent rent agreements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: left; text-indent: 0in; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Present Value of Long-term Leases&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: left; text-indent: 0in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div&gt; &lt;table style="border-collapse: collapse; margin-left: 1.55in; min-width: 700px;" cellspacing="0" cellpadding="0"&gt;  &lt;tr style="vertical-align: bottom"&gt; &lt;td style="white-space: nowrap; font-size: 10pt; border-bottom: Black 1pt solid"&gt;(in thousands):&lt;/td&gt; &lt;td style="white-space: nowrap; font-size: 10pt; font-weight: bold; padding-bottom: 1pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td colspan="3" style="white-space: nowrap; font-size: 10pt; font-weight: bold; text-align: center; border-bottom: Black 1pt solid"&gt;November 30, 2019&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt; &lt;td style="width: 87%; font-size: 10pt; text-align: left"&gt;Right-of-use assets, net&lt;/td&gt; &lt;td style="width: 1%; font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="width: 1%; font-size: 10pt; text-align: left"&gt;$&lt;/td&gt; &lt;td style="width: 10%; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;598,784&lt;/div&gt;&lt;/td&gt; &lt;td style="width: 1%; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: White"&gt; &lt;td style="font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="font-size: 10pt; text-align: right"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt; &lt;td style="font-size: 10pt; text-align: left"&gt;Current portion of lease liability&lt;/td&gt; &lt;td style="font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;295,856&lt;/div&gt;&lt;/td&gt; &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: White"&gt; &lt;td style="font-size: 10pt; text-align: left; padding-bottom: 1pt"&gt;Lease liability, less current portion&lt;/td&gt; &lt;td style="font-size: 10pt; padding-bottom: 1pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="border-bottom: Black 1pt solid; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="border-bottom: Black 1pt solid; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;302,928&lt;/div&gt;&lt;/td&gt; &lt;td style="border-bottom: Black 1pt solid; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt; &lt;td style="text-indent: 20pt; font-size: 10pt; text-align: left; padding-bottom: 1pt"&gt;Total lease liability&lt;/td&gt; &lt;td style="font-size: 10pt; padding-bottom: 2.5pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="border-bottom: Black 2.5pt double; font-size: 10pt; text-align: left"&gt;$&lt;/td&gt; &lt;td style="border-bottom: Black 2.5pt double; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;598,784&lt;/div&gt;&lt;/td&gt; &lt;td style="border-bottom: Black 2.5pt double; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt;  &lt;/table&gt; &lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 17; Value: 1 --&gt;     &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0pt 0"&gt;As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019, &lt;/div&gt;the weighted-average remaining lease term was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2.3&lt;/div&gt; years. The Company&amp;#x2019;s lease agreements do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; provide a readily determinable implicit rate nor is it available to the Company from its lessors. Instead, as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019, &lt;/div&gt;the Company estimates the weighted-average discount rate for its operating leases to be &lt;div style="display: inline;

margin: 0pt 0"&gt;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2019, &lt;/div&gt;the Compensation Committee of the Board of Directors of the Company approved the material terms of an annual bonus plan for the Company&amp;#x2019;s executive officers as well as certain officers and employees for the fiscal year ending &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2020. &lt;/div&gt;For fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020&lt;/div&gt; 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, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;75%&lt;/div&gt; of the amount of their individual bonus payout will be determined based upon the Company&amp;#x2019;s actual EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020&lt;/div&gt; compared to a pre-established target EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020,&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;25%&lt;/div&gt; 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 bonuses &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be paid to executive officer participants in both cash and shares of NTIC common stock, with the exact amount and percentages 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020.&lt;/div&gt; There was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$400,000&lt;/div&gt; accrued for management bonuses for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019 &lt;/div&gt;compared to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$450,000&lt;/div&gt; accrued for management bonuses for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2018.&lt;/div&gt;&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;Three joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea, Thailand and India) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;51.4%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt; joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea, Thailand, France, Germany and India) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;69.6%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2019.&lt;/div&gt;&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; probable or the amount is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; estimable, or both, if there is a reasonable possibility that material loss &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have been incurred. In the opinion of management, as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019, &lt;/div&gt;the amount of liability, if any, with respect to these matters, individually or in the aggregate, will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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>

This standard also requires certain disclosures about stranded tax effects.

The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Plan replaced the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan with respect to future grants; and, therefore, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; further awards &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be made under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan.

Subject to adjustment as provided in the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Plan, up to a maximum of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;800,000&lt;/div&gt; shares of the Company&amp;#x2019;s common stock are issuable under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Plan. Options granted generally have a term of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ten&lt;/div&gt; years and become exercisable over a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;- or &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt;- year period beginning on the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-year anniversary of the date of grant.

The ESPP is compensatory for financial reporting purposes.

The fair value of option grants is determined at date of grant using the Black-Scholes option pricing model with the assumptions listed below. The Company recognized compensation expense of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$318,818&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$357,980&lt;/div&gt; during the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018,&lt;/div&gt; respectively, related to the options that vested during such time period. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019, &lt;/div&gt;the total compensation cost for non-vested options &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; yet recognized in the Company&amp;#x2019;s consolidated statements of operations was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,018,956.&lt;/div&gt; Stock-based compensation expense of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,018,956&lt;/div&gt; is expected through the remainder of fiscal year &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020,&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$20,834&lt;/div&gt; is expected to be recognized during fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2021,&lt;/div&gt; based on outstanding options as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 30, 2019. &lt;/div&gt;Future option grants will impact the compensation expense recognized.

This standard also requires certain disclosures about stranded tax effects.
