provides a more general description of the terms and conditions of the shares of common stock that may, from time to time, be sold by
the selling stockholders identified in such prospectus under our resale registration statement on Form S-3 that we filed with the SEC.

that stabilize, maintain or otherwise affect the price of our common stock during and after the offering. Specifically, an underwriter
may over-allot or otherwise create a short position in our common stock for its own account by selling more shares of common stock than
we have sold to such underwriter. The underwriters may close out any short positions by either exercising their option to purchase additional
shares or purchasing shares in the open market.</P>

<P STYLE="text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In addition, the underwriters may stabilize or maintain the price of
our common stock by bidding for or purchasing shares in the open market and may impose penalty bids. If penalty bids are imposed, selling
concessions allowed to broker-dealers participating in this offering are reclaimed if shares previously distributed in this offering are
repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize
or maintain the market price of our common stock at a level above that which might otherwise prevail in the open market. The imposition
of a penalty bid may also affect the price of our common stock to the extent that it discourages resales of our common stock. The magnitude
or effect of any stabilization or other transactions is uncertain. These transactions may be effected on the Nasdaq Capital Market or
otherwise and, if commenced, may be discontinued at any time.</P>

members may also engage in passive market making transactions in our common stock on the Nasdaq Capital Market. Passive market making
consists of displaying bids on the Nasdaq Capital Market limited by the prices of independent market makers and effecting purchases limited
by those prices in response to order flow. Rule 103 of Regulation M promulgated by the SEC limits the amount of net purchases
that each passive market maker may make and the displayed size of each bid. Passive market making may stabilize the market price of our
common stock at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.</P>

by reference herein, contains &ldquo;forward-looking statements&rdquo; within the meaning of Section 27A of the Securities Act of 1933,
as amended (the &ldquo;Securities Act&rdquo;), and Section 21E of the Exchange Act. In some cases, you can identify forward-looking statements
by the words &ldquo;anticipate,&rdquo; &ldquo;believe,&rdquo; &ldquo;continue,&rdquo; &ldquo;could,&rdquo; &ldquo;estimate,&rdquo; &ldquo;expect,&rdquo;
&ldquo;intend,&rdquo; &ldquo;may,&rdquo; &ldquo;might,&rdquo; &ldquo;objective,&rdquo; &ldquo;ongoing,&rdquo; &ldquo;plan,&rdquo; &ldquo;predict,&rdquo;
&ldquo;project,&rdquo; &ldquo;potential,&rdquo; &ldquo;should,&rdquo; &ldquo;will,&rdquo; or &ldquo;would,&rdquo; or the negative of these
terms, or other comparable terminology intended to identify statements about the future. We have based our forward-looking statements
on our current expectations and projections about trends affecting our business and industry and other future events. Although we do not
make forward-looking statements unless we believe we have a reasonable basis for doing so, we cannot guarantee their accuracy. Forward-looking
statements are subject to substantial risks and uncertainties that could cause our results or experiences, or future business, financial
condition, results of operations or performance, to differ materially from our historical results or those expressed or implied in any
forward-looking statement contained in this news release. Factors which could have a material adverse effect on our operations and future
prospects or which could cause actual results to differ materially from our expectations include, but are not limited to: the impact of
the COVID-19 pandemic, including the emergence of new more contagious and/or vaccine-resistant strains of the virus and the impact of
vaccination efforts, including the efficacy and public acceptance of vaccinations, on our business, employees, supply and distribution
chains and the global economy; the effects of negative or worsening regional and worldwide economic conditions or market instability on
our business, including effects on purchasing decisions by our customers; our ability to continue to generate revenue from products sold
into mature markets; our ability to develop, market, and sell new products; our ability to succeed with our new software offerings; fluctuations
in our revenue due to the project-based timing of orders from certain customers; unpredictable timing of our revenues due to the lengthy
sales cycle for our products and services and potential delays in customer completion of projects; our ability to accurately forecast
future demand for our products; delays in qualifying revisions of existing products; constraints or delays in the supply of, or quality
control issues with, certain materials or components; difficulties associated with the delivery, quality or cost of our products from
our contract manufacturers or suppliers; risks related to the outsourcing of manufacturing and international operations; difficulties
associated with our distributors or resellers; intense competition in our industry and resultant downward price pressure; rises in inventory
levels and inventory obsolescence; undetected software or hardware errors or defects in our products; cybersecurity risks; our ability
to obtain appropriate industry certifications or approvals from governmental regulatory bodies; changes in applicable U.S. and foreign
government laws, regulations, and tariffs; our ability to successfully implement our acquisitions strategy or integrate acquired companies;
uncertainty as to the future profitability of acquired businesses, and delays in the realization of, or the failure to realize, any accretion
from acquisition transactions; acquiring, managing and integrating new operations, businesses or assets, and the associated diversion
of management attention or other related costs or difficulties; our ability to protect patents and other proprietary rights and avoid
infringement of others&rsquo; proprietary technology rights; the level of our indebtedness, our ability to service our indebtedness and
the restrictions in our debt agreements; our ability to attract and retain qualified management; and any additional factors included in
our Annual Report on Form 10-K for the fiscal year ended June 30, 2021, filed with SEC on August 27, 2021, including in the section entitled
&ldquo;Risk Factors&rdquo; in Item 1A of Part I of such report, and in our other public filings with the SEC, including in any prospectus
supplement. In addition, actual results may differ as a result of additional risks and uncertainties of which we are currently unaware
or which we do not currently view as material to our business. For these reasons, investors are cautioned not to place undue reliance
on any forward-looking statements. The forward-looking statements we make speak only as of the date on which they are made. We expressly
disclaim any intent or obligation to update any forward-looking statements after the date hereof to conform such statements to actual
results or to changes in our opinions or expectations, except as required by applicable law or the rules of the Nasdaq Stock Market LLC.
If we do update or correct any forward-looking statements, investors should not conclude that we will make additional updates or corrections.</P>

risks. Before making an investment decision, in addition to the other information contained in or incorporated by reference in this prospectus
and any prospectus supplement, you should carefully consider the specific risks set forth under the heading &ldquo;Risk Factors&rdquo;
in our most recent Annual Report on Form&nbsp;10-K filed with the SEC, as such risk factors may be amended, supplemented or superseded
from time to time by other reports we file with the SEC, including subsequent Annual Reports on Form&nbsp;10-K and Quarterly Reports on
Form&nbsp;10-Q, <FONT STYLE="background-color: white">and the risk factors described under the caption &ldquo;Risk Factors&rdquo; in any
applicable prospectus supplement</FONT>. See &ldquo;Where You Can Find More Information&rdquo; and &ldquo;Information We Incorporate by
Reference.&rdquo; If any of these risks actually occurs, our business, results of operations and financial condition could suffer. In
that case, the trading price of our common stock could decline, and you could lose all or part of your investment. Additional risks and
uncertainties not currently known to us, or that we currently believe are immaterial, may also adversely affect our business, operating
results and financial condition and the value of an investment in our common stock. In addition, past financial performance may not be
a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods.</P>

connection with any offering, the underwriters may purchase and sell common stock</FONT> in the open market. These transactions may include
short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters
of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of bids or purchases
made for the purpose of preventing a decline in the market price of the common stock while an offering is in progress. The underwriters
also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount
received by it because the underwriters have repurchased common stock sold by or for the account of that underwriter in stabilizing or
short-covering transactions. These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the
common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If
these activities are commenced, they may be discontinued by the underwriters at any time. Underwriters may engage in over-allotment. If
any underwriters create a short position in the common stock in an offering in which they sell more common stock than are set forth on
the cover page of the applicable prospectus supplement, the underwriters may reduce that short position by purchasing the common stock
in the open market.</P>

described in any prospectus supplement and any documents incorporated by reference herein or therein. Our business, financial condition
or results of operations could be materially adversely affected by any of these risks and uncertainties. In addition, the trading
price of our securities could decline due to any of these risks and uncertainties, and you may lose all or part of your investment.
