a framework for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value
as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants
at the measurement date. Additionally, the guidance requires the use of valuation techniques that maximize the use of observable
inputs and minimize the use of unobservable inputs. These inputs are prioritized below:</P>

carrying value of long-lived assets, including intangible assets, when events and circumstances warrant such a review. The carrying
value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from such asset is separately identifiable
and is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds
the fair market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash flows discounted
at a rate commensurate with the risk involved.</P>

Standards Board (&ldquo;FASB&rdquo;) issued Accounting Standards Update (&ldquo;ASU&rdquo;) No. 2015-17, &ldquo;<I>Income Taxes
(Topic 740): Balance Sheet Classification of Deferred Taxes</I>&rdquo; (&ldquo;ASU 2015-17&rdquo;). The standard requires that
deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current and
noncurrent. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016.
Early adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred tax
assets and liabilities. The Company adopted ASU 2015-17 during the first quarter of fiscal year 2018 on a retrospective basis.
Accordingly, the Company reclassified the current deferred taxes to noncurrent on its February 28, 2017 Consolidated Balance Sheet,
which increased noncurrent deferred tax assets by $315,171. There was no impact on the results of operations as a result of the
adoption of ASU 2015-17.</P>

<P STYLE="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0">In computing the impact, the fair value of each option is estimated on the date
of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk free interest rate; volatility;
and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent
management&rsquo;s best estimates, but these estimates involve inherent uncertainties and the application of management judgment.
As a result, if factors change and the Company uses different assumptions, the Company&rsquo;s stock-based compensation expense
could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and
only recognize expense for those shares expected to vest. In estimating the Company&rsquo;s forfeiture rate, the Company analyzed
its historical forfeiture rate, the remaining lives of unvested options, and the number of vested options as a percentage of total
options outstanding. If the Company&rsquo;s actual forfeiture rate is materially different from its estimate, or if the Company
reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what
the Company has recorded in the current period.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0"><B>&nbsp;</B></P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">We have developed a unique and proprietary series of ultrasonic atomizing nozzles
and systems, which are being used in an increasing variety of electronics, advanced energy (solar and fuel cells), medical device,
glass, textiles and food applications. These nozzles are electrically driven and create a fine, uniform, low velocity spray of
atomized liquid particles, in contrast to common pressure nozzles. These characteristics create a series of commercial applications
that benefit from the precise, uniform, thin coatings that can be achieved. When combined with significant reductions in liquid
waste and less overspray than can be achieved with ordinary pressure nozzle systems, there is lower environmental impact and lower
energy use.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">Ultrasonic nozzle systems atomize low to medium viscosity liquids by converting
electrical energy into mechanical motion in the form of high frequency ultrasonic vibrations that break liquids into minute drops
that can be applied to surfaces at low velocity. The principal advantage of these nozzle systems is that they use much less liquid
than competitive nozzle systems to attain the required coatings on solar cells, fuel cells, glass, advanced textiles, food and
food packaging, circuit boards, medical devices and many other coating applications. This advantage translates into precise thin
films and lower costs for materials, less costly liquid consumption, less energy required for subsequent drying operations and
less release into the environment of spray that would typically bounce back and scatter while using competitive nozzle systems.
These factors are increasingly important to customers at a time of rising commodity and energy costs and supply limitations.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">We use our core ultrasonic spray coating technology to provide both standard and
customized coating solutions to a wide range of manufacturing companies, enabling them to reduce their product costs and to develop
new products with superior features and quality. Presently, our customers are in six major industries: electronics, advanced energy
(solar and fuel cells), medical device, glass, textiles and foods. Our systems are widely used by leading high tech companies and
research institutions, as well as by governmental, defense, energy and health agencies around the world.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0 0 0 0.5in">Wide area modular coating system &ndash; designed to be used in applications
that require efficient web-coating or wide area spraying capability. One module can cover substrates from six inches to 24 inches
wide, depending on the application. Much greater widths can be achieved by linking modules together, and these systems have been
applied in glass lines of up to 13 feet wide. A large number of systems have been sold over the past six years, and this application
holds promise for the future due to cost and environmental savings demonstrated at customer sites. It uses non-clogging ultrasonic
atomizing nozzles to produce a low velocity, highly controllable spray. The WideTrack System offers significant advantages over
conventional pressure-spray methods in a broad range of applications such as non-woven fabrics, float glass, or odd-shaped industrial
or consumer products. Since the ultrasonic spray can be easily controlled, it is possible to use fewer chemicals and less water
and energy in applying coatings to glass, textiles, food products and packaging materials than with traditional nozzles. This also
results in reduced environmental impact due to less overspray.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">The discussion and analysis of the Company&rsquo;s financial condition and results
of operations are based upon the consolidated financial statements, which have been prepared in accordance with accounting principles
generally accepted in the United States of America. The preparation of these financial statements requires the Company to make
estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses, and related disclosure
on contingent assets and liabilities at the date of the financial statements. Actual results may differ from these estimates under
different assumptions and conditions.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">Critical accounting policies are defined as those that are reflective of significant
judgments and uncertainties, and may potentially result in materially different results under different assumptions and conditions.
The Company believes that critical accounting policies are limited to those described below. For a detailed discussion on the application
of these and other accounting policies see Note 2 to the Company&rsquo;s consolidated financial statements included in Form 10-K
for the year ended February 28, 2017.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0"><B>&nbsp;</B></P>

<P STYLE="font: 11pt Cambria,serif; margin: 0"><I>Accounting for Income Taxes</I></P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">As part of the process of preparing the Company&rsquo;s condensed consolidated financial
statements, the Company is required to estimate its income taxes. Management judgment is required in determining the provision
for the deferred tax asset.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0"><I>Stock-Based Compensation</I></P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">The computation of the expense associated with stock-based compensation requires
the use of a valuation model. ASC 718 is a complex accounting standard, the application of which requires significant judgment
and the use of estimates, particularly surrounding Black-Scholes assumptions such as stock price volatility, expected option lives,
and expected option forfeiture rates, to value equity-based compensation. The Company currently uses a Black-Scholes option pricing
model to calculate the fair value of its stock options. The Company primarily uses historical data to determine the assumptions
to be used in the Black-Scholes model and has no reason to believe that future data is likely to differ materially from historical
data. However, changes in the assumptions to reflect future stock price volatility and future stock award exercise experience could
result in a change in the assumptions used to value awards in the future and may result in a material change to the fair value
calculation of stock-based awards. ASC 718 requires the recognition of the fair value of stock compensation in net income. Although
every effort is made to ensure the accuracy of our estimates and assumptions, significant unanticipated changes in those estimates,
interpretations and assumptions may result in recording stock option expense that may materially impact our financial statements
for each respective reporting period.</P>

of the Company.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">The Company does not issue or invest in financial instruments or derivatives for
trading or speculative purposes. Substantially all of the operations of the Company are conducted in the United States, and, as
such, are not subject to material foreign currency exchange rate risk. All of our sales transactions are completed in US dollars.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">Although the Company's assets included $1,699,000 in cash and $4,447,000 in marketable
securities, the market rate risk associated with changing interest rates in the United States is not material.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">The Company has established and maintains &ldquo;disclosure controls and procedures&rdquo;
(as those terms are defined in Rules 13a &ndash;15(e) and 15d-15(e) under the Securities and Exchange Act of 1934 (the &ldquo;Exchange
Act&rdquo;). Christopher L. Coccio, Chief Executive Officer (principal executive) and Stephen J. Bagley, Chief Financial Officer
(principal accounting officer) of the Company, have evaluated the Company&rsquo;s disclosure controls and procedures as of November
30, 2017. Based on this evaluation, they have concluded that the Company&rsquo;s disclosure controls and procedures were effective
to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is
(1) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules
and forms, and (2) accumulated and communicated to Management, including our Chief Executive Officer and Chief Financial Officer,
to allow timely decisions regarding timely disclosure.</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 11pt Cambria,serif; margin: 0">In addition, there were no changes in the Company&rsquo;s internal controls over
financial reporting during the third fiscal quarter of 2018 that have materially affected, or are reasonably likely to materially
affect, internal controls over financial reporting.</P>

This guidance establishes a common definition for fair&#13;value to be applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes&#13;a framework for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value&#13;as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants&#13;at the measurement date. Additionally, the guidance requires the use of valuation techniques that maximize the use of observable&#13;inputs and minimize the use of unobservable inputs. These inputs are prioritized below:&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0; background-color: white"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif;

These securities are valued using inputs observable in active markets for identical securities and are&#13;therefore classified as Level&amp;#160;1 within the Company&amp;#8217;s fair value hierarchy. The Company&amp;#8217;s marketable securities&#13;are considered to be available-for-sale investments as defined under ASC 320 &amp;#8220;Investments &amp;#8211; Debt and Equity Securities.&amp;#8221;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt; - The Company accounts for income taxes under the asset&#13;and liability method. Under this method, deferred income taxes are recognized for the tax consequences of &amp;#34;temporary differences&amp;#34;&#13;by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts&#13;and the tax basis of existing assets and liabilities. If it is more likely than not that some portion or all of a deferred tax&#13;asset will not be realized, a valuation allowance is recognized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&lt;b&gt;&lt;i&gt;Intangible Assets&lt;/i&gt;&lt;/b&gt;&lt;i&gt; -&lt;/i&gt;Include costs of patent applications which&#13;are deferred and charged to operations over seventeen years for domestic patents and twelve years for foreign patents. The accumulated&#13;amortization of patents is $147,000 and $139,000 at November 30, 2017 and February 28, 2017, respectively. Annual amortization&#13;expense of such intangible assets is expected to be approximately $11,000 per year for the next five years.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&lt;b&gt;&lt;i&gt;Interim Reporting&lt;/i&gt;&lt;/b&gt; - The attached summary condensed consolidated financial&#13;information does not include all disclosures required to be included in a complete set of financial statements prepared in conformity&#13;with accounting principles generally accepted in the United States of America. Such disclosures were included with the financial&#13;statements of the Company at February 28, 2017, and included in its report on Form 10-K. Such statements should be read in conjunction&#13;with the data herein.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;The financial information reflects all adjustments, normal and recurring, which,&#13;in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. The preparation&#13;of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions&#13;that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the&#13;financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ&#13;from those estimates. The results for such interim periods are not necessarily indicative of the results to be expected for the&#13;year.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&lt;b&gt;&lt;i&gt;Inventories&lt;/i&gt;&lt;/b&gt;&lt;i&gt; - &lt;/i&gt;Inventories are stated at the lower of cost or&#13;market.

The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash&#13;flow from such asset is separately identifiable and is less than its carrying value. In that event, a loss is recognized based&#13;on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Fair market value is determined&#13;primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&lt;b&gt;&lt;i&gt;Management Estimates&lt;/i&gt;&lt;/b&gt;&lt;i&gt; - &lt;/i&gt;The preparation of financial statements&#13;in conformity with accounting principles generally accepted in the United States of America requires management to make estimates&#13;and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities&#13;at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

The standard requires that&#13;deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current and&#13;noncurrent. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016.&#13;Early adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred tax&#13;assets and liabilities. The Company adopted ASU 2015-17 during the first quarter of fiscal year 2018 on a retrospective basis.&#13;Accordingly, the Company reclassified the current deferred taxes to noncurrent on its February 28, 2017 Consolidated Balance Sheet,&#13;which increased noncurrent deferred tax assets by $315,171. There was no impact on the results of operations as a result of the&#13;adoption of ASU 2015-17.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;Other than, Accounting Standards Update (&amp;#8220;ASU&amp;#8221;) No. 2015-17, &amp;#8220;&lt;i&gt;Income&#13;Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes&lt;/i&gt;&amp;#8221; (&amp;#8220;ASU 2015-17&amp;#8221;) discussed above, all new&#13;accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence, the adoption&#13;of these new accounting pronouncements once effective are not expected to have an impact on the Company.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&lt;b&gt;&lt;i&gt;Reclassifications &amp;#8211;&lt;/i&gt;&lt;/b&gt; Where appropriate, certain reclassifications&#13;have been made to the prior period to conform to the presentations of the current period.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The assumptions used in calculating the fair value of share-based payment awards represent&#13;management&amp;#8217;s best estimates, but these estimates involve inherent uncertainties and the application of management judgment.&#13;As a result, if factors change and the Company uses different assumptions, the Company&amp;#8217;s stock-based compensation expense&#13;could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and&#13;only recognize expense for those shares expected to vest. In estimating the Company&amp;#8217;s forfeiture rate, the Company analyzed&#13;its historical forfeiture rate, the remaining lives of unvested options, and the number of vested options as a percentage of total&#13;options outstanding. If the Company&amp;#8217;s actual forfeiture rate is materially different from its estimate, or if the Company&#13;reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what&#13;the Company has recorded in the current period.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0"&gt;For the nine months ended November 30,&#13;2017 and 2016, net income and earnings per share reflect the actual deduction for stock-based compensation expense.

This guidance establishes a common definition for fair&#13;value to be applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes&#13;a framework for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value&#13;as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants&#13;at the measurement date. Additionally, the guidance requires the use of valuation techniques that maximize the use of observable&#13;inputs and minimize the use of unobservable inputs.

other comprehensive income (loss) in stockholders&#8217; equity. Realized losses and declines in value below cost judged to be
other than temporary, if any, are included as a component of asset impairments expense in the consolidated statement of operations.
The fair value of the available-for-sale investments are based on quoted market prices. The Company&#8217;s fair value determination

Company follows the guidance in the &#8220;Fair Value Measurements and Disclosure Topic&#8221; of the Accounting Standards Codification
for assets and liabilities measured at fair value on a recurring basis. This guidance establishes a common definition for fair
value to be applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes
a framework for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value
as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants
at the measurement date. Additionally, the guidance requires the use of valuation techniques that maximize the use of observable
inputs and minimize the use of unobservable inputs. These inputs are prioritized below:</p>

financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ
from those estimates. The results for such interim periods are not necessarily indicative of the results to be expected for the

on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Fair market value is determined
primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved.</p>

Standards Board (&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) No. 2015-17, &#8220;<i>Income Taxes
(Topic 740): Balance Sheet Classification of Deferred Taxes</i>&#8221; (&#8220;ASU 2015-17&#8221;). The standard requires that
deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current and
noncurrent. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016.
Early adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred tax
assets and liabilities. The Company adopted ASU 2015-17 during the first quarter of fiscal year 2018 on a retrospective basis.
Accordingly, the Company reclassified the current deferred taxes to noncurrent on its February 28, 2017 Consolidated Balance Sheet,
which increased noncurrent deferred tax assets by $315,171. There was no impact on the results of operations as a result of the
adoption of ASU 2015-17.</p>

<p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0">In computing the impact, the fair value of each option is estimated on the date
of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk free interest rate; volatility;
and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent
management&#8217;s best estimates, but these estimates involve inherent uncertainties and the application of management judgment.
As a result, if factors change and the Company uses different assumptions, the Company&#8217;s stock-based compensation expense
could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and
only recognize expense for those shares expected to vest. In estimating the Company&#8217;s forfeiture rate, the Company analyzed
its historical forfeiture rate, the remaining lives of unvested options, and the number of vested options as a percentage of total
options outstanding. If the Company&#8217;s actual forfeiture rate is materially different from its estimate, or if the Company
reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what
the Company has recorded in the current period.</p>

2017 and 2016, net income and earnings per share reflect the actual deduction for stock-based compensation expense. The
impact of applying ASC 718 approximated $32,000 and $33,000 in additional compensation expense during each of the nine month
periods ended November 30, 2017 and 2016, respectively. Such amounts are included in general and administrative expenses on the statement
of operations. The expense for stock-based compensation is a non-cash expense item.</p><span></span>

<p style="font: 11pt Cambria,serif; margin-top: 0; margin-bottom: 0; margin-left: 0">The Company has a $750,000 revolving line of credit at prime which was 4.25% at
November 30, 2017. The line of credit is collateralized by all of the assets of the Company, except for the land and buildings.
The line of credit is payable on demand and must be retired for a 30-day period once annually. If the Company fails to perform
the 30-day annual pay down or if the bank elects to terminate the credit line, the bank may at its option convert the outstanding
balance to a 36-month term note with payments including interest in 36 equal installments. As of November 30, 2017, the Company&#8217;s
outstanding balance was $0, and the unused credit line was $750,000.</p><span></span>

(Topic 740): Balance Sheet Classification of Deferred Taxes</i>&#8221; (&#8220;ASU 2015-17&#8221;). The standard requires that
deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current and
noncurrent. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016.
Early adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred tax
assets and liabilities. The Company adopted ASU 2015-17 during the first quarter of fiscal year 2018 on a retrospective basis.
Accordingly, the Company reclassified the current deferred taxes to noncurrent on its February 28, 2017 Consolidated Balance Sheet,
which increased noncurrent deferred tax assets by $315,171. There was no impact on the results of operations as a result of the
adoption of ASU 2015-17.</p>
