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>

Accounting 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>

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: 10pt Times New Roman,serif; margin: 0"><B>&nbsp;</B></P>

<P STYLE="font: 10pt Times New Roman,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: 10pt Times New Roman,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman,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: 10pt Times New Roman,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman,serif; margin: 0">We use our core ultrasonic spray coating technology to provide both standard

<P STYLE="font: 10pt Times New Roman,serif; margin: 0">Float Glass - The manufacture of float glass occurs under extremely harsh
conditions of elevated temperatures. Our ultrasonic coating technology provides this manufacturing process with the means to precisely
and uniformly apply anti-stain, and other specialty chemical agents, on the hot glass. Our customers benefit from an improved quality
product, enhanced productivity and significantly reduced expenditures on annual maintenance, often resulting in a return on investment
of less than one year. Based on this equipment&rsquo;s recent successful performance, our systems are now specified by many global
float glass manufacturers as their equipment of choice.</P>

<P STYLE="font: 10pt Times New Roman,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman,serif; margin: 0">Panel Glass &ndash; Panel glass primarily refers to glass used in the manufacture
of TV&rsquo;s, tablets, phones, lenses and other consumer viewing devices. By using our coating equipment, manufacturers can apply
a wide range of functional coatings to these devices, such as conductive layers, hard coatings, anti-reflection, and other nano-material
formulations.</P>

<P STYLE="font: 10pt Times New Roman,serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman,serif; margin: 0">The equipment we offer to the glass industry is typically the WideTrack
and FlexiCoat platforms.</P>

value adding coatings onto fabrics, such as anti-microbial, anti-stain, flame retardant and moisture barriers. The current manufacturing
process for applying these expensive coatings creates significant waste of material, energy and water. We are working with this
industry to incorporate our ultrasonic technology, often in combination with unique pre and post treatments of the coating materials,
to reduce the effective material and energy usage by as much as 90%.</P>

<P STYLE="font: 10pt Times New Roman,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>

primarily due to increases in sales of our higher gross margin stent coating units and servo units. In addition, for the three
months ended May 31, 2017, the Company experienced a decrease in manufacturing salaries due to reduced headcount.</P>

<P STYLE="font: 10pt Times New Roman,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>

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&rsquo;). 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 May 31, 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>

This guidance establishes a common definition for fair value to be&#13;applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes a framework&#13;for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value as the price&#13;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: 10pt Times New Roman,serif; margin: 0; text-align: justify; background-color: white"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif;

These securities are valued using inputs observable in active markets for identical securities&#13;and are 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: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt; - The Company accounts for income taxes under&#13;the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of &amp;#34;temporary&#13;differences&amp;#34; by applying enacted statutory tax rates applicable to future years to differences between the financial statement&#13;carrying amounts and the tax basis of existing assets and liabilities. If it is more likely than not that some portion or all of&#13;a deferred tax asset will not be realized, a valuation allowance is recognized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 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&#13;which are deferred and charged to operations over seventeen years for domestic patents and twelve years for foreign patents. The&#13;accumulated amortization of patents is $141,000 and $139,000 at May 31, 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: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Interim Reporting&lt;/i&gt;&lt;/b&gt; - The attached summary condensed consolidated&#13;financial information does not include all disclosures required to be included in a complete set of financial statements prepared&#13;in conformity with accounting principles generally accepted in the United States of America. Such disclosures were included with&#13;the financial statements of the Company at February 28, 2017, and included in its report on Form 10-K. Such statements should&#13;be read in conjunction with the data herein.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;The financial information reflects all adjustments, normal and recurring,&#13;which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. The&#13;preparation of financial statements in conformity with generally accepted accounting principles 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. Actual results&#13;could differ from those estimates. The results for such interim periods are not necessarily indicative of the results to be expected&#13;for the year.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 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&#13;cost or market. Cost is determined using the first-in, first-out (FIFO) method for raw materials, subassemblies and work-in-progress&#13;and the specific identification method for finished goods.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Land and Buildings &amp;#8211; &lt;/i&gt;&lt;/b&gt;Land and buildings are stated at&#13;cost. Buildings are being depreciated by use of the straight-line method based on an estimated useful life of forty years.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Long-Lived Assets&lt;/i&gt;&lt;/b&gt;&lt;i&gt; - &lt;/i&gt;The Company periodically evaluates&#13;the carrying value of long-lived assets, including intangible assets, when events and circumstances warrant such a review. The&#13;carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from such asset is separately&#13;identifiable and is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying&#13;value exceeds the fair market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash&#13;flows discounted at a rate commensurate with the risk involved.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 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&#13;statements in conformity with accounting principles generally accepted in the United States of America requires management to make&#13;estimates 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&#13;that deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current&#13;and noncurrent. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15,&#13;2016. Early adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred&#13;tax 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: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0"&gt;Other than, Accounting Standards Update (&amp;#8220;ASU&amp;#8221;) No. 2015-17,&#13;&amp;#8220;&lt;i&gt;Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes&lt;/i&gt;&amp;#8221; (&amp;#8220;ASU 2015-17&amp;#8221;) discussed&#13;above, all new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence,&#13;the adoption 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: 10pt Times New Roman,serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0 4.5pt 0 0"&gt;&lt;b&gt;&lt;i&gt;Reclassifications &amp;#8211;&lt;/i&gt;&lt;/b&gt; Where appropriate, certain&#13;reclassifications 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&#13;awards represent management&amp;#8217;s best estimates, but these estimates involve inherent uncertainties and the application of management&#13;judgment. As a result, if factors change and the Company uses different assumptions, the Company&amp;#8217;s stock-based compensation&#13;expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate&#13;and 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: 10pt Times New Roman,serif; margin: 0 4.5pt 0 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman,serif; margin: 0 4.5pt 0 0"&gt;For the three months ended May 31, 2017 and 2016, net income and&#13;earnings per share reflect the actual deduction for stock-based compensation expense. The impact of applying ASC 718 approximated&#13;$10,000 and $8,000 in additional compensation expense during the three months ended May 31, 2017 and 2016, respectively. Such amounts&#13;are included in general and administrative expenses on the statement of operations. The expense for stock-based compensation is&#13;a non-cash expense item.&lt;/p&gt;</us-gaap:ShareBasedCompensationArrangementByShareBasedPaymentAwardOptionsVestedAndExpectedToVestExercisableTableTextBlock>

This guidance establishes a common definition for fair value to be&#13;applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes a framework&#13;for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value as the price&#13;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.

available for sale investments are carried at fair value with the unrealized gains or losses, net of tax, included as a component
of accumulated 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 method is discussed below in &#8220;Fair Value of Financial Instruments.&#8221;</p>

<p style="font: 10pt Times New Roman,serif; margin: 0"><b><i>Earnings Per Share</i></b><i> - </i>Basic earnings per share (&#8220;EPS&#8221;)
is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects
the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into
common stock.</p>

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>

the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of &#34;temporary
differences&#34; by applying enacted statutory tax rates applicable to future years to differences between the financial statement
carrying amounts 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 asset will not be realized, a valuation allowance is recognized.</p>

expense of such intangible assets is expected to be approximately $11,000 per year for the next five years.</p>

in conformity with accounting principles generally accepted in the United States of America. Such disclosures were included with
the financial statements of the Company at February 28, 2017, and included in its report on Form 10-K. Such statements should
be read in conjunction with the data herein.</p>

<p style="font: 10pt Times New Roman,serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman,serif; margin: 0">The financial information reflects all adjustments, normal and recurring,
which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. The
preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities
at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates. The results for such interim periods are not necessarily indicative of the results to be expected

<p style="font: 10pt Times New Roman,serif; margin: 0"><b><i>Inventories</i></b><i> - </i>Inventories are stated at the lower of
cost or market. Cost is determined using the first-in, first-out (FIFO) method for raw materials, subassemblies and work-in-progress
and the specific identification method for finished goods.</p>

<p style="font: 10pt Times New Roman,serif; margin: 0"><b><i>Land and Buildings &#8211; </i></b>Land and buildings are stated at

<p style="font: 10pt Times New Roman,serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman,serif; margin: 0"><b><i>Long-Lived Assets</i></b><i> - </i>The Company periodically evaluates
the 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>

<p style="font: 10pt Times New Roman,serif; margin: 0"><b><i>New Accounting Pronouncements-</i></b> In November 2015, the Financial
Accounting 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>

above, all new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence,
the adoption of these new accounting pronouncements once effective are not expected to have an impact on the Company.</p>

<p style="font: 10pt Times New Roman,serif; margin: 0 4.5pt 0 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>

<p style="font: 10pt Times New Roman,serif; margin: 0 4.5pt 0 0">For the three months ended May 31, 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
$10,000 and $8,000 in additional compensation expense during the three months ended May 31, 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></td>

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 May 31, 2017, and February 28, 2017, the Company&#8217;s

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>

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>

The loan 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.<span></span>
