large corporate data centers and the development and licensing of information technology (&#8220;IT&#8221;) asset management software.
In late 2014, ISA entered negotiations with Duos Technologies, Inc. (&#8220;duostech&#8482;&#8221;) for the purposes of executing a merger
between the two organizations (also known as a &#8220;reverse triangular merger&#8221;). Incorporated under the laws of Florida on November
30, 1990, duostech&#8482; operated in various industry segments, specializing in the design, development and deployment of proprietary
technology applications and turn-key engineered systems. This transaction was completed on April 1, 2015, whereby duostech&#8482; became
a wholly owned subsidiary of ISA. After the merger was completed, ISA changed its corporate name to Duos Technologies Group, Inc (together
with its subsidiaries, &#8220;Duos,&#8221; &#8220;we,&#8221; &#8220;us&#8221; or the &#8220;Company&#8221;). The Company, based in Jacksonville,

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company, operating under its brand name <span style="font-family: Arial, Helvetica, Sans-Serif; font-size: 8pt; color: #548DD4"><b>duos</b></span><b><span style="font-family: Arial, Helvetica, Sans-Serif; font-size: 8pt">tech</span></b>,
designs, develops, deploys and operates intelligent technology solutions for inspecting and evaluating moving objects. Its technology
focus is within the Vision Technology market sector and, more specifically, the Machine Vision subsector. Machine Vision companies provide
imaging-based automatic inspection and analysis for process control for industry with potential expansion into other markets. Duos has
developed key technologies over the past several years in software, industry specific hardware and artificial intelligence and has demonstrated
industrial strength usability of its systems supporting rail, logistics and intermodal businesses that streamline operations, improve
safety and reduce costs. Our employee team include engineering subject matter expertise in hardware, software, and information technology
as well as industry specific applications of artificial intelligence also referred to as Expert Artificial Intelligence.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos is currently developing industry solutions for
its target markets which will address rail, trucking, aviation and other vehicle-based processes. Duos initial offering, the Railcar Inspection
Portal (RIP), provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
railcar inspections of trains while they are moving at full speed. The RIP utilizes a variety of sophisticated optical, laser and speed
sensors to scan each passing railcar to create a high-resolution image-set of the top, sides and undercarriage. These images are then
processed with our edge data center using artificial intelligence (AI) algorithms to identify safety and security defects on each railcar.
The algorithms are developed in conjunction with industrial application experts, in this case Railcar Mechanical Engineers, to provide
specific guidance in the analysis (&#8220;human in the loop&#8221;). Within minutes of the railcar passing through the RIP,
a detailed report is sent to the customer where they are able to action identified issues. This solution has the potential to transform
the railroad industry by increasing safety, improving efficiency and reducing costs. The Company has already deployed this system with
several Class 1 railroads and anticipates an increased demand from transit and other railroad customers along with selected government
agencies that operate and/or manage rail traffic. The Company has deployed RIPs in Canada, Mexico and the United States and anticipates
expanding this solution into Europe and Australia in coming years.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates gatehouse operations where transport trucks enter and exit large logistics and intermodal facilities.
This solution incorporates a similar set of sensors, data processing and artificial intelligence to streamline the customer&#8217;s logistics
transactions and tracking and can also automate the security and safety inspection if called for. The Company has already deployed this
system with one large North American retailer and anticipates increased demand from other large retailers, railroad intermodal operators
and select government agencies that manage logistics and border crossing points. The Company is evaluating other solutions for moving
vehicles including aircraft, which could provide similar benefits in terms of safety and efficiency for required inspections as part of
an operations process.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Federal regulations require each railcar/train to
be inspected for mechanical defects prior to leaving a rail yard. Founded in 1934, the Association of American Railroads (AAR) is responsible
for setting the standards for the safety and productivity of the U.S./North American freight rail industry, and by extension, has established
the inspection parameters for the rail industry&#8217;s rolling stock. Also known as the &#8220;Why Made&#8221; codes, the AAR established
approximately 110 inspection points under its guidelines for mechanical inspections.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under current practice, inspections are conducted
manually, a very labor intensive and inefficient process that only covers a select number of inspection points and can take several hours
per train. We believe our Railcar Inspection Portal has the potential to reduce this inspection to minutes while the train is moving at
speed improving safety, reducing dwell time and optimizing maintenance.</p>

intermodal yard. This automates the logistics transaction, improves throughput and can also be used to automate security and maintenance
screening/detection if desired by the customer.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We believe the opportunity for our Rail Inspection
Portal business is substantial and our number one priority at this time. We are currently providing this solution to three of seven Class
1 railroad operators with 10 systems already deployed. Because of our early leadership position, we have been able to accumulate experience
and intellectual property that we believe would be time consuming and expensive for a new competitor to replicate. Furthermore, we believe
we have the ability to upgrade and scale our solutions with additional technologies in the future. We believe that the current market
for our technologies is substantial. At the same time, we recognize that the technology life cycle is fast and evolving. Potential competitors
could move into this sector, and it is possible that some Class 1 railroads could develop their own solutions that limit our total addressable
market.</p>

Potential customers include commercial retail logistics and intermodal operators, Class 1 rail intermodal operators that are moving large
amounts of automobiles, and U.S. Government agencies such as the Department of Defense and the Department of Homeland Security. Today,
we currently have 20 production systems in use, but we believe the greenfield opportunity here to be substantial. We have identified over
900 lanes of traffic within nearly 300 facilities as potential business opportunities in the near-term.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">One of our primary commercial goals is to develop
innovative technology solutions and target potential &#8220;greenfield&#8221; market spaces in order to maximize our business footprint
and give us the ability to help define the market parameters for the future.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">With regards to our Railcar Inspection Portal (RIP),
we believe that we are the most advanced technology currently focused on 360-degree inspections of railcars and have limited direct competition
domestically or globally.&#160; There are several companies that do provide visual and optical (laser) based imaging systems, but they
are specifically designed to focus on a single aspect of a railcar whereas our latest RIP will identify 50+ inspection points on each
car.&#160; This is not to be confused with track inspection technologies, where we do not compete. We are not aware of any other company,
that creates images of the entire car from multiple perspectives and with many different inspection points.&#160; Other companies that
participate in the visual and optical (laser) based railcar inspection systems market include Trimble Rail Solutions/Beena Vision and
KLD Labs, both primarily focused on wheel and brake inspections and the Class 1 railroads themselves developing &#8220;in-house&#8221;
solutions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Our Automated Logistics Information System (ALIS)
also represents an opportunity to expand into a mature market that we believe has a significant technology gap.&#160; While most facilities,
such as distribution centers, that process commercial trucks in and out have sophisticated software management applications for logistics
control, they have most often not implemented an advanced gatehouse automation solution.&#160; Historically, this category was referred
to as &#8220;Automated Gate Systems&#8221; or AGS.&#160; The purpose of AGS technology is to streamline entry in to and exit out of facilities.&#160;
The marketplace for this was mostly seaports and intermodal transfer facilities and was relatively expensive technology to deploy.&#160;
We identified a market gap with regards to distribution facilities that all currently utilize manual processes and heavy staffing to accomplish
commercial truck entry and exit.&#160; The barrier to entry for distribution centers was predominately &#8220;cost&#8221;, as well as
the requirement for a different set of logistics management software and tools.&#160; The current competition includes Nascent with a
primary focus on seaports and intermodal transfer facilities.</p>

also hired a divisional Chief Operating Officer (COO) with a strong background in operations in multiple former assignments. The Company&#8217;s
CFO will continue in the same role providing continuity and multiple years of public company experience. The Company&#8217;s Board of
Directors is being strengthened with the addition of a retired Chief Operating Officer for a Class 1 railroad with more than 50 years
of experience in the rail industry. The shareholders also approved the appointment of our CEO to the Board of Directors.</p>

using a combination of in-house fabrication, commercial off-the-shelf technology, and outsourced manufacturing. On-site installations
are performed using a combination of in-house project managers and engineers and using third-party sub-contractors as needed. Throughout
the process of design, develop, deploy and operate, the Company maintains responsibility for all aspects. Our internal manufacturing operations
consist primarily of materials procurement, assembly, testing and quality control by our engineers. If not manufactured internally, we
use third-party manufacturing partners to produce our hardware related components and hardware products and we most often complete final
assembly, testing and quality control processes for these components and products. Our manufacturing processes are based on standardization
of components across product types, centralization of assembly and distribution centers, and a &#8220;build-to-order&#8221; methodology
in which products generally are built only after customers have placed firm orders. For most of our hardware products, we have existing
alternate sources of supply.</p>

challenges with macro-economic impacts, specifically inflation and supply chain disruption. Although these started to be identified in
late 2021, we believe they are manifesting themselves in ways that could hinder our business growth in the future. Specifically, the ability
to source key components and certain implementation services will dictate just how quickly the Company can meet desired installation deadlines.
In the industries in which we operate, the time from concept to contract can be substantial. Although we are now adapting to these challenges,
previous bids that have been submitted could be challenging to execute within the financial framework and execution times originally envisaged.
We continue to have dialogue with our customers regarding potential price increases and implementation delays, but we may suffer some
economic impacts as a result of this. Revenue recognition could be delayed as result of these factors and profitability could be impacted
due to higher costs for materials and other services. The Company will continue to monitor the situation and update shareholders as the
situation unfolds.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #0E0E0E">Our business operates in an environment
of long bid to contract award cycles. Our customer&#8217;s bid requirements are such that firm pricing is expected on much or all of our
proposal and as such we must commit to certain commercial terms and conditions such as pricing. In addition, the Company hires employees
and contractors to perform most (if not all) of the work required to complete a contract. We are beginning to experience the impacts of
inflation upon previously forecasted costs including employees that require higher salaries, contractors demanding higher prices for jobs
and higher costs for materials necessary to complete contracts. While we endeavor to charge additional costs to our customers, in some
cases this may not be possible contractually and as a result our profitability may suffer as a result. Although we anticipate these effects
to be mitigated in the long term, we cannot be assured that this will be possible in all or any instances and as such our revenue, profitability
and growth prospects may suffer as a result of this.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We believe that operators in the business sectors
we are focused on continue to be cautious about sustained economic growth and seek to maintain or improve profitability through cost control
and constrained spending. While our core technologies are designed to address cost reduction, other factors may cause companies to delay
or cancel capital projects, including the implementation of our products and services. In addition, the business sectors in which we are
focused are under financial pressure to reduce capital investment which may make it more difficult for us to close large contracts in
the immediate future. We believe there is a growing market trend toward more customers exploring operating expense models as opposed to
capital expense models for procuring technology. We believe the market trend toward operating expense models will continue as customers
seek ways of reducing their overhead and other costs. All of the foregoing may result in continued pressure on our ability to increase
our revenue and may potentially create competitive pricing pressures and price erosion. If these or other conditions limit our ability

agreements with our employees and consultants. We may not always be able to enforce these agreements and may fail to enter into any such
agreement in every instance when appropriate. We license from third-parties certain technology used in and for our products. These third-party
licenses are granted with restrictions; therefore, such third-party technology may not remain available to us on terms beneficial to us.
Our failure to enforce and protect our intellectual property rights or obtain from third parties the right to use necessary technology

Although we do not have operations outside North America at this time, we may compete for contracts in other countries in the future.
Effective intellectual property protection may be unavailable, or limited, in some foreign countries in which we may do business, such

previously authorized and unissued securities, resulting in the dilution of the ownership interests of holders of our common stock. We

shares of common stock or other securities that are convertible into or exercisable for common stock in future public offerings or private
placements for capital raising purposes or for other business purposes. The future issuance of a substantial number of shares of common
stock into the public market, or the perception that such issuance could occur, could adversely affect the prevailing market price of

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_cp_change_275"></span>On February 26,
2021, the Company entered into a Securities Purchase Agreement (the &#8220;Purchase Agreement&#8221;) with certain existing investors
in the Company (the &#8220;Purchasers&#8221;). Pursuant to the Purchase Agreement, the Purchasers purchased 4,500 shares of a newly authorized
Series C Convertible Preferred Stock (the &#8220;Series C Convertible Preferred Stock&#8221;), and the Company received proceeds of $4,500,000.
The Purchase Agreement contains customary representations, warranties, agreements and indemnification rights and obligations of the parties.<span id="a_cp_change_274"></span>
As of December 31, 2021, there are 2,500 shares of Series C Convertible Preferred Stock issued and outstanding.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_cp_change_285"></span>Under the Purchase

stock) without shareholder approval and the terms of the Series C Convertible Preferred Stock limit its convertibility to a number of
shares less than the 20% limit, until the Stockholder Approval is obtained. The Company obtained shareholder approval (the &#8220;Stockholder
Approval&#8221;) in order to issue shares of common stock underlying the Series C Convertible Preferred Stock at a price less than the
greater of book or market value which equal 20% or more of the number of shares of common stock outstanding before the issuance<span id="a_cp_change_284"></span>.</p>

in accordance with accounting principles generally accepted in the United States (&#8220;GAAP&#8221;). These accounting principles require

reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates,
judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements
as well as the reported amounts of revenues and expenses during the periods presented. Our consolidated financial statements would be
affected to the extent there are material differences between these estimates and actual results. In many cases, the accounting treatment

changes to its senior management team in 2020 and further changes in 2021 to improve operational effectiveness. In addition to new &#8220;C&#8221;

position of Chief Technology Officer. The Company&#8217;s Board of Directors was strengthened with the addition of two very experienced
leaders. The first is a retired Chief Operating Officer for a Class 1 railroad with more than 50 years of experience in the rail industry.
The second is a retired Army General Officer and former CEO of a large, global security and training company contracting with multiple
U.S. Government Agencies.</p>

over the course of 2022 and the Company&#8217;s primary customers have indicated readiness to order more equipment and services should
the Company execute as expected on key deliverables over the next few months.</p>

Transport Canada and Association of American Railroad (AAR) standards. The Company is expanding its focus in the rail industry to encompass
passenger transportation and is currently in the last stages of a bid for a large, multi-year contract with a national rail carrier. If
successful, the Company is expected to deliver at least two RIP solutions along with a long-term services agreement in late 2022 or early
2023.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For the full year 2021, there was a 3% overall
increase in revenues compared to 2020. The increase was driven by new revenues being recorded after lengthy delays in receiving
&#8220;notices to proceed&#8221; for anticipated new contracts earlier in the year pushed delivery dates into the second half of
this year and into 2022. There was a slight decrease in revenue from systems which was more than offset by a 15% increase in
services revenue, most of which is recurring in nature. The Company is focusing on increasing its business from services and the
increase is the result of new contracts for existing and new systems. This trend is expected to continue into 2022. While
anticipated orders continue to be delayed, we are encouraged by the breadth and scope of recent bids in which we have participated,
indicating an expected increase in orders in the early months of 2022. As previously discussed, management cautions that because of
the delays in anticipated start dates, certain installations may produce revenues towards the end of 2022, some of which may
ultimately be recorded in 2023. Additionally, although the industries in which we operate are showing early signs of recovery from
the delays as a result of the Covid-19 pandemic, other macro-economic effects are anticipated to impact us, including inflation and
the current supply chain issues which are extending deadlines for shipment of key components used in our technology systems. The
effect of this will be to push some revenue recognition later in the year or into 2023 as previously mentioned. The effects if
inflation are not quantifiable at the current time but are beginning to be evident in increased costs for materials and labor and
may result in higher costs for project implementation that cannot be wholly or even partially passed on to our customers and thus
resulting in delaying our progress towards profitability.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s capital structure continues to
allow us to weather the unexpected delays without significant operational impact and enables us to pursue large projects requiring the
ability to deploy major resources. It should be noted that the Company recently increased its working capital to account for an increase
in pre-contract procurement activities to avoid a slowdown in revenues caused by delays in receiving certain components. The Company undertook
a major review of operations during 2021 and made significant changes in staffing including additional engineering staff and revamping
its software development and Artificial Intelligence staffing. Although in early 2021 the Company implemented a &#8220;rapid development&#8221;
initiative which was intended to be able to respond to market driven demand more quickly, this effort has been somewhat negated by ongoing
supply chain issues. Where this effort has shortened delivery times on major projects and was expected to result in significant revenue
growth in the last six months of the year and beyond, the previously discussed supply chain issues have not allowed the anticipated benefits
to be realized at this time. The Company is monitoring the situation and is continuing to procure materials ahead of contract award.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also expects to continue the growth with
new revenue from other existing customers which we expect to be coming on-line in the next several months. As previously noted, the slight
decrease in technology systems revenues was offset by an increase in services revenue as the result of new maintenance contracts being
established as well as renewals of existing contracts and a shift to the next generation of technology systems which are currently being
installed. The services portion of revenues are driven by successful completion on projects and represent services and support for those
installations. The Company expects to continue the growth with new, long term recurring revenue from existing customers which will be
coming on-line in the next several months.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Cost of revenues largely comprises equipment, labor
and overhead necessary to support the implementation of new systems and support and maintenance of existing systems. Cost of revenues
on technology systems increased during the period compared to the equivalent period in 2020 by a greater amount than the increase in revenues.
The main reason for the continuing high level of cost is the result of additional work being necessary on certain of the Company&#8217;s
installations to resolve newly identified quality issues which are now mostly resolved as well as higher costs of materials due to supply
chain disruptions. There was also a significant increase in cost related to the new deployment of an undercarriage technology. Many of
these costs were not envisioned by the original scope of work. However, the costs are expected to be much lower going forward as a percentage
of the overall system price. As previously noted, the Company&#8217;s organization and related cost structure was realigned to give the
capability to manufacture, install and support multiple production systems simultaneously. Prior to this realignment, the Company&#8217;s
organization was focused on primarily research and development with implementation resources being allocated as necessary. In accordance
with this shift in structure, certain staff were re-assigned or replaced, and new staff added in key areas, particularly software engineering,
IT and AI.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In conjunction with this change, increased costs are
now being recognized against project and support revenues with a similar reduction in costs previously recognized for research and development,
engineering development and internal support. In concert with this, there is a continued focus on construction costs and savings through
efficiency, but the Company has elected to expand its key employees in anticipation of expected sales growth in technology systems and
services in 2022. As previously discussed in the first quarter of 2021, certain expenses related to installed equipment upgrades were
greater than anticipated for a variety of reasons including cost overruns on the first installation of new technologies and certain implementation
inefficiencies related to Covid-19 restrictions such as extended quarantines and additional contract staff necessary to complete projects
on time. These changes had a negative impact on the gross margin (see below), but this is expected to be a short-term impact, offset by
increases in revenue later in 2022. It is also expected to have positive long-term impact as the Company is prepared to deliver a higher
number of systems in a given period, with a shorter time of implementation and with better quality and reliability as the operations become
standardized in anticipation of expected higher demand for systems, particularly in the rail industry.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Cost of revenues increased on services and consulting
versus the increase in revenues on services and consulting. The overall positive trend on service and consulting revenue is expected
to continue as more of the Company&#8217;s business is from recurring revenue. Costs of service are expected to increase in future years
but at a slower rate than revenue growth. The Company focused on streamlining support operations in 2021 and despite the additional resources
allocated to these activities in anticipation of higher recurring revenue in 2022 and beyond we expect higher gross margins as the Company
grows. As discussed previously, the impact of inflation may negatively affect the costs of revenues such that we may experience higher
costs for materials and labor, including higher employee and sub-contractor costs that cannot be passed along in all cases. Management
is continuing to monitor this situation and expects to take actions as the full impact of these cost increases is understood. This may
take the form of higher prices and continued evaluation of costs to attempt to reduce the overall costs of a system to offset the additional
expenses, although this is not assured.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously discussed, the Company has revamped
its operations to support an anticipated increase in the number of new systems going forward. The resultant additional cost of revenues,
while somewhat offset by decreases in G&amp;A expenses, was not covered by a comparable increase in revenues as of the third quarter 2021.
However, there was an improvement in the fourth quarter of 2021 which is part of an overall improving trend in this area. The overall
negative gross margin was $2,559,170 versus 2020 which was a positive $235,836. The small increase in year over year revenues, more than
50% of which came in the fourth quarter is a positive trend. The main reason for the continuing high level of cost is the result of additional
development work being necessary on certain of the Company&#8217;s more complex installations as well as higher costs of materials due
to supply chain disruptions. There was also a significant increase in cost related to the new deployment of an undercarriage technology.
Many of these costs were not envisioned by the original scope of work. These higher costs are anticipated to be offset in by higher revenues
in 2022 with the net result being a move to a positive gross margin as the business expands. In addition, we anticipate an improvement
in the overall gross margin for the full year reporting in 2022, with much of the improvement coming in the second half of the year. As
previously discussed, certain macro-economic factors including the current supply chain issues could delay that improvement into 2023.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Overall operating expenses were lower by 29% in 2021
offsetting some of the increased costs previously discussed. A 72% increase in sales and marketing costs was more than offset by a 44%
decrease in overall administration costs. This decrease was partially due to the recording of the ex-CEO&#8217;s separation agreement
during the same period in 2020 and other overall reductions in cost as part of the restructuring of the business. Additionally, certain
costs to support the organization as it operated at that time were eliminated as an offset to the increases in operations staff as described
previously.</p>

31, 2021 and 2020 were $7,456,951 and $6,634,428, respectively. The increase in losses from operations during the year was the result
of mostly flat revenues, higher cost of sales related to the recent organizational changes and certain
cost overruns on the initial deployment of some newly developed systems. The combination of these resulted in negative gross margin for
the year, partially offset by lower total operating expenses. The Company previously expected to achieve profitability in the fourth quarter
through improvements in gross margin from higher revenues and lower operating costs although the Company did not achieve breakeven as
the result of unanticipated additional costs for implementations for certain new complex technologies being installed for the first time.
Due to contract and manufacturing delays earlier in 2021, implementation was delayed until late in the year and took place in locations
with harsh weather conditions requiring additional staffing. The Company is expecting improvements in operating margins in 2022 although
it does not expect to breakeven on an operating basis until 2023 or thereafter depending upon the impacts of supply chain and inflation.</p>

2021 and 2020 was $20,268 and $150,137, respectively. The reduction in interest expense was primarily due to the Company&#8217;s equity
financing actions in 2020 reducing or eliminating debt. This was partially offset by interest earned from substantial additional capital
held in reserve (see Other Income).</p>

ended December 31, 2021 and 2020 was $6,579,378 and $4,231,439, respectively. The increase in net cash used in operations for the year
ended December 31, 2021 was the result of higher expenditures related to current projects as previously discussed as well as expenditures
related to future project execution in anticipation of new projects starting in the fourth quarter of 2021. In addition, there are several
changes in assets and liabilities that increased the use of cash in operations including charges related to the new building that the
company now occupies including a $600,000 security deposit. Notable changes are an increase in deferred revenue as the result of an increase
in pre-paid service contracts offset by decreases in contract liabilities. Additionally, $1,410,270 in funding from the CARES Act PPP
loan program plus deferred interest was forgiven. The Company accrued interest in the amount of $648 during 2021 and $10,577 during 2020.
The effects of other changes were largely neutral.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During 2021, we funded our operations through
the sale of our equity (or equity linked) securities, and through revenues generated and cash received from ongoing project execution,
services and associated maintenance revenues. As of March 28, 2022, we have cash on hand of approximately $5,700,000. We have approximately
$165,500 in monthly lease and other mandatory payments, not including payroll and ordinary expenses which are due monthly.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On a long-term basis, our liquidity is dependent
on the continuation and expansion of operations and receipt of revenues. Our current capital and revenues are sufficient to fund such
expansion although we are now less dependent on timely payments by our customers for projects and work in process, however we expect such
timely payments to continue. Material cash requirements will be satisfied within the normal course of business including substantial upfront
payments from our customers prior to starting projects. In some limited cases, the Company may elect to purchase materials and supplies
in advance of contract award but where there is a high probability of that award. Most, if not all, high value items that are pre-purchased,
can be re-purposed if necessary. The maximum amount of material cash requirements not currently supported by up-front customer deposits
is expected to be less than $1million.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As reflected in the accompanying consolidated financial
statements, the Company had a negative working capital of $651,381 and an accumulated deficit of $45,497,051 at December 31, 2021. During
the same period in 2020, the Company had a positive working capital of $2,167,058 and an accumulated deficit of $39,488,150. In a previous
financial report, the Company had raised substantial doubt about continuing as a going concern. This was principally due to a lack of
working capital prior to an underwritten offering which was completed during the first quarter of 2022 (the &#8220;2022 Offering&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously noted, the Company raised $4,500,000
from existing shareholders through the issuance of Series C Convertible Preferred Stock. Although additional investment is not assured,
the Company is comfortable that it would be able to raise sufficient capital to support expanded operations based on an anticipated increase
in business activity. In the long run, the continuation of the Company as a going concern is dependent upon the ability of the Company
to continue executing the plan described above, generate enough revenue, and attain consistently profitable operations. Although the current
global pandemic related to the coronavirus (Covid-19) has affected our operations, particularly in supply chain, we now believe that this
is expected to be an ongoing issue and our working capital assumptions reflect this new reality. The Company cannot currently quantify
the uncertainty related to the pandemic and its effects on our customers in the coming quarters. We have analyzed our cash flow under
&#8220;stress test&#8221; conditions and have determined that we have sufficient liquid assets on hand to maintain operations for at least
twelve months from the date of this report. A notable recent success is the approval of the Company for &#8220;bonding&#8221; in the amount
of approximately$8 million for an upcoming major project.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company was successful in securing a loan of $1,410,270
during the second quarter of 2020 from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#8217;s
cash reserves. This loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free. The Company has also
been successful in increasing its working capital surplus after receiving proceeds from the 2021 Offering of $4,500,000 and more recently,
in the first quarter of 2022, receiving net proceeds of approximately $5,500,000 from the successful takedown of the Company&#8217;s &#8220;shelf
registration&#8221; S3. This gives us the capital required to fund the fundamental business changes that we undertook in the last quarter
of 2020, further changes throughout 2021 and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue, and
re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and profitability and
focusing product strategy on opportunities that are likely to bear results in the relatively short term. During 2021, management took
further significant actions including reorganizing our engineering and technical teams and selectively improving organizational efficiency
to effectively grow the business as the expected order flow resumes in 2022. Upon completion of the 2022 Offering, management has raised
sufficient working capital to meet its needs for the next 12-months without the need to raise further capital. Since the advent of the
Covid-19 pandemic, the Company has experienced a significant slowdown in closing new projects due to cautious actions by current and potential
clients. We continue to be successful in identifying new business opportunities and are focused on re-establishing a backlog of projects.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Management believes that, at this time, the conditions
in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including a $5.5M injection of funds from a sale of securities, significant recent orders and the overall stabilization of the business
indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve months from the
issuance of this report. We continue executing the plan to grow our business and achieve profitability without the requirement to raise
additional capital for existing operations for 2022 although we may do so to fund selective opportunities that may arise. Management has
extensively evaluated our requirements for the next 12 months and has determined that the Company currently has sufficient cash to operate
for at least that period.</p>

assets and liabilities. On an ongoing basis, we evaluate our estimates. The most significant estimates in the accompanying consolidated
financial statements include the allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other
long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress toward contract completion,
valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on historical experience and on various
other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about
the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company constructs intelligent technology
systems consisting of materials and labor under customer contracts. Revenues and related costs on project revenue are recognized based
on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance does not create an asset
with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a
profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured
and revenue is recognized accordingly.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC 606-10-55-187 through 192.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract
labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged
to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in &#8220;contract
assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract liabilities&#8221;.
However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Arrangements with customers may involve multiple elements
including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project
is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple elements
may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while
other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for
a multiple element arrangement is as follows:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each element is accounted for separately when each
element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple
element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined
with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of
revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and
software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling
price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based
on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase
maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue
recognition purposes.&#160;</p>

the collections on the account, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances.
The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required
allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based
on how recently payments have been received from customers.</p>

which requires recognition of impairment of long-lived assets in the event the net book value of such assets exceed the estimated future
undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that
long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison
of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.</p>

maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Our management,
under the supervision and with the participation of our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer,
evaluated the effectiveness of our internal control over financial reporting as of the end of the period covered by this report. In making
this assessment, our management used the criteria set forth in the framework contained in Internal Control&#160;&#8212; Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO)<i>.</i> Based on that evaluation, our management
concluded that our internal control over financial reporting was effective as of the end of the period covered by this report based on
those criteria.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Our internal control over financial reporting is a
process designed under the supervision of our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for
external purposes in accordance with generally accepted accounting principles, or GAAP. Internal control over financial reporting includes
those policies and procedures that (i)&#160;pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of our assets, (ii)&#160;provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures are being made only in accordance
with authorizations of our management and directors, and (iii)&#160;provide reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.</p>

are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies
or procedures may deteriorate.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The 2021 Plan is administered by the Compensation
Committee of the Board, which consists of three members of the Board, each of whom is a &#8220;non-employee director&#8221; within the
meaning of Rule 16b-3 promulgated under the Exchange Act and an &#8220;outside director&#8221; within the meaning of Code Section 162(m).
Among other things, the Compensation Committee has complete discretion, subject to the express limits of the 2021 Plan, to determine the
directors, employees and nonemployee consultants to be granted an award, the type of award to be granted, the terms and conditions of
the award, the form of payment to be made and/or the number of shares of Common Stock subject to each award, the exercise price of each
option and base price of each stock appreciation right (&#8220;SAR&#8221;), the term of each award, the vesting schedule for an award,
whether to accelerate vesting, the value of the Common Stock underlying the award, and the required withholding, if any. The Compensation
Committee may amend, modify or terminate any outstanding award, provided that the participant&#8217;s consent to such action is required
if the action would impair the participant&#8217;s rights or entitlements with respect to that award. The Compensation Committee is also
authorized to construe the award agreements and may prescribe rules relating to the 2021 Plan. Notwithstanding the foregoing, the Compensation
Committee does not have any authority to grant or modify an award under the 2021 Plan with terms or conditions that would cause the grant,
vesting or exercise thereof to be considered nonqualified &#8220;deferred compensation&#8221; subject to Code Section 409A.</p>

SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock
unit awards and unrestricted stock awards to non-employee directors, officers, employees and nonemployee consultants of the Company or
its affiliates. We have reserved a total of 1,000,000 shares of Common Stock for issuance as or under awards to be made under the 2021
Plan. If any award expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available
for grant under the 2021 Plan.</p>

non-employee directors and/or consultants would be eligible to participate in the 2021 Plan as well.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The 2021 Plan provides for either &#8220;incentive
stock options&#8221; (&#8220;ISOs&#8221;), which are intended to meet the requirements for special federal income tax treatment under
the Code, or &#8220;nonqualified stock options&#8221; (&#8220;NQSOs&#8221;); provided, however, that ISOs may only be issued if our shareholders
approve the 2021 Plan at the Annual Meeting. Stock options may be granted on such terms and conditions as the Compensation Committee may
determine; provided, however, that the per share exercise price under a stock option may not be less than the fair market value of a share
of the Company&#8217;s Common Stock on the date of grant and the term of the stock option may not exceed 10 years (110% of such value
and five years in the case of an ISO granted to an employee who owns (or is deemed to own) more than 10% of the total combined voting
power of all classes of capital stock of the Company or a parent or subsidiary of the Company). ISOs may only be granted to employees.
In addition, the aggregate fair market value of our Common Stock covered by one or more ISOs (determined at the time of grant) which are
exercisable for the first time by an employee during any calendar year may not exceed $100,000. Any excess is treated as a NQSO.</p>

under the 2021 Plan. An SAR granted in tandem with a stock option (i) is exercisable only at such times, and to the extent, that the related
stock option is exercisable in accordance with the procedure for exercise of the related stock option; (ii) terminates upon termination
or exercise of the related stock option (likewise, the Common Stock option granted in tandem with a SAR terminates upon exercise of the
SAR); (iii) is transferable only with the related stock option; and (iv) if the related stock option is an ISO, may be exercised only
when the value of the stock subject to the stock option exceeds the exercise price of the stock option. An SAR that is not granted in
tandem with a stock option is exercisable at such times as the Compensation Committee may specify.</p>

by the Compensation Committee of the Board, which currently consists of two members of the Board, each of whom is a &#8220;non-employee
director&#8221; within the meaning of Rule 16b-3 promulgated under the Exchange Act and an &#8220;outside director&#8221; within the meaning
of Code Section 162(m). Among other things, the Compensation Committee had complete discretion, subject to the express limits of the 2016
Plan, to determine the directors, employees and nonemployee consultants to be granted an award, the type of award to be granted the terms
and conditions of the award, the form of payment to be made and/or the number of shares of common stock subject to each award, the exercise
price of each option and base price of each stock appreciation right (&#8220;SAR&#8221;), the term of each award, the vesting schedule
for an award, whether to accelerate vesting, the value of the common stock underlying the award, and the required withholding, if any.
The Compensation Committee may amend, modify or terminate any outstanding award, provided that the participant&#8217;s consent to such
action is required if the action would impair the participant&#8217;s rights or entitlements with respect to that award. The Compensation
Committee is also authorized to construe the award agreements and may prescribe rules relating to the 2021 Plan. Notwithstanding the foregoing,
the Compensation Committee does not have any authority to modify an award under the 2021Plan with terms or conditions that would cause
the grant, vesting or exercise thereof to be considered nonqualified &#8220;deferred compensation&#8221; subject to Code Section 409A.</p>

than the fair market value of a share of the Company&#8217;s common stock on the date of grant and the term of the stock option could
not exceed 10 years (110% of such value and five years in the case of an ISO granted to an employee who owned (or was deemed to own) more

could only be granted to employees. In addition, the aggregate fair market value of our common stock covered by one or more ISOs (determined
at the time of grant) which are exercisable for the first time by an employee during any calendar year could not exceed $100,000. Any

contractor master services agreement (the &#8220;Services Agreement&#8221;) with Luceon, LLC, a Florida limited liability company, owned
by our former Chief Technology Officer, David Ponevac. The Services Agreement provided that Luceon would provide support services including
management, coordination or software development services and related services to duos. In January 2019, additional services were contracted
with Luceon for TrueVue360&#8482; primarily for software development through the provision of 7 additional full-time contractors located
in Slovakia at a cost of $16,250 for January initially, rising to $25,583 after fully staffed, per month starting February 2019. This
was in addition to the existing contract of $7,480 per month for duos for 4 full-time contractors which increased to $8,231 per month
in June of 2019. During 2020 efforts in reducing cost, Luceon reduced its staff for the TrueVue360 software development team from a staff
of 7 to 3 full-time employees at a cost of $11,666 per month starting June 1, 2020. As of January 1, 2021, the Company no longer records
activities in TrueVue360 and has combined billings for a total of $20,986 per month. For the years ended December 31, 2021 and 2020, the
total amount expensed is $93,422 and $335,334, respectively. The Company had no open accounts payable with Luceon at December 31, 2021.
On May 14, 2021, the Company formally ended its relationship with Luceon in concert with the resignation of our Chief Technology Officer
and as such there is no longer a related party relationship.</p>

sheets of Duos Technologies Group, Inc. and Subsidiaries (the &#8220;Company&#8221;) as of December 31, 2021 and 2020, the related consolidated
statements of operations, changes in stockholders&#8217; equity and cash flows for each of the two years in the period ended December
31, 2021 and the related notes (collectively referred to as the &#8220;consolidated financial statements&#8221;). In our opinion, the
consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December
31, 2021 and 2020, and the consolidated results of its operations and its cash flows for each of the two years in the period ended December
31, 2021, in conformity with accounting principles generally accepted in the United States of America.</p>

of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we
engaged to perform, an audit of internal control over financial reporting. As part of our audits we are required to obtain an understanding
of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company&#8217;s

the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures

management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide
a reasonable basis for our opinion.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As described in footnote 1, &#8220;Revenue Recognition
&#8211; Technology Systems&#8221; and footnote 9, &#8220;Contract Accounting&#8221; to the consolidated financial statements, the Company
recognizes revenue over time using a cost-based input methodology in which significant judgement is required to estimated costs to complete
projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue
to recognize. In addition, contract assets on uncompleted contracts represent costs and estimated earnings in excess of billings and/or
cash received on uncompleted contracts accounted for under the percentage of completion contract method. Contract liabilities on uncompleted
contracts represent billings and/or cash received that exceed accumulated revenues recognized on uncompleted contracts accounted for under
the percentage of completion contract method.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We identified this percentage of completion revenue
recognition as a critical audit matter. Auditing management&#8217;s estimates and judgments regarding forecasts of total estimated costs
to complete projects is especially challenging and complex.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The primary procedures we performed to address this
critical audit matter included (a) evaluated the reasonableness of management&#8217;s cost estimates to complete projects by comparing
them to historical information, year to date current information and other supporting contracts or information, (b) agreed cost details
to supporting documents, (c) confirmed billings with customers and/or tracing cash receipts to bank statements, (d) computed the revenue
earned and recognized, (e) computed the contract asset or liability and (f) performed ratio analysis and gross margin comparisons when
applicable on a sample of technology systems revenues.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As summarized in Footnote 2 &#8220;Liquidity&#8221;
to the consolidated financial statements, the Company has a history of net losses and net cash used in operating activities and believes
such conditions will continue for a period of time into the future. These are considered adverse conditions or events that lead management
to consider whether there is substantial doubt about the ability of the entity to continue as a going concern for a reasonable period
of time.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">However, management believes that cash raises through
an underwritten offering for $5.5 million in the first quarter of 2022 created a cash balance and positive working capital that alleviates
the substantial doubt related to going concern and the need for a going concern risk disclosure.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We identified the going concern risk analysis as a
critical audit matter. Auditing management&#8217;s going concern analysis including their process to develop the analysis and the projections
of future cash flows, operating trends, and assessments of internal and external matters that may affect the Company&#8217;s future operations
and cash flows involved a high degree of subjectivity. Additionally, auditing management&#8217;s plans to address the going concern risk
involved highly subjective auditor judgment.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The primary procedures we performed to address this
critical audit matter included (a) Assessed the reasonableness of management&#8217;s process for developing their assessment of whether
a going concern risk exists, (b) Assessed the reasonableness of assumptions management used in their future cash flow projections including
comparison to prior year results, consideration of positive and negative evidence impacting management&#8217;s forecasts, and consideration
of the Company&#8217;s financing arrangements in place as of the report date, (c) Developed our own independent calculation of expected
source and use of funds and needs of the Company over the one year period from the date of issuance of the consolidated financial statements,
(d) Confirmed cash balances as of December 31, 2021 with the banks and tested management&#8217;s bank reconciliations, (e) Identified
management&#8217;s plans for dealing with the adverse conditions and events discussed above and assessed the reasonableness of the assumptions
of such plans, (f) Assessed whether it is probable that management&#8217;s plans, when implemented, will mitigate the adverse effects
of the conditions and events discussed above, (g) Concluded whether substantial doubt exists as to whether the Company can continue as
a going concern for a period of one year after the consolidated financial statements are issued and (h) considered the effect of such
conclusion on the consolidated financial statement disclosures and our report of an independent registered public accounting firm.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#8220;AI&#8221;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Through September 30, 2021, the Company also provided
professional and consulting services for large data centers and had developed a system for the automation of asset information marketed
as DcVue&#8482;. The Company had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing
teams. DcVue was based upon the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license
to our customers as a licensed software product.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in
conformity with accounting principles generally accepted in the United States of America requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosures 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 may
differ from these estimates. The most significant estimates in the accompanying consolidated financial statements include the
allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates
of net contract revenues and the total estimated costs to determine progress towards contract completion, estimates of the valuation
of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based
awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these estimates.</p>

undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that
long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison
of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For revenues related to technology systems, the
Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimated costs

amount of revenue to recognize.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_Aci_Pg63"></span>Accordingly, the Company
now bases its revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance
does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192. (see Note 9)</p>

business in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605-25 which addresses
revenue recognition for the software industry. The general criteria for revenue recognition under ASC 985-605 for our Company, which sells
software licenses, which do not require any significant modification or customization, is that revenue is recognized when persuasive evidence
of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Arrangements with customers may involve multiple elements
including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project
is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple elements
may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while
other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for
a multiple element arrangement is as follows:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each element is accounted for separately when each
element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple
element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined
with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of
revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and
software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling
price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based
on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase
maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue
recognition purposes.</p>

leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance
sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases
that contain both lease and non-lease components as a single lease component.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For contracts entered into on or after the effective
date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company&#8217;s assessment
is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially
all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.</p>

the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments

of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We plan to adopt this pronouncement

the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2022, and we do not

respectively. In previous financial reports, the Company had raised substantial doubt about continuing as a going concern. This was principally
due to a lack of working capital prior to an underwritten offering which was completed during the first quarter of 2022 (the &#8220;2022
Offering&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously noted, the Company raised $4,500,000
from existing shareholders through the issuance of Series C Convertible Preferred Stock. Although additional investment is not assured,
the Company is comfortable that it would be able to raise sufficient capital to support expanded operations based on an anticipated increase
in business activity. In the long run, the continuation of the Company as a going concern is dependent upon the ability of the Company
to continue executing the plan described above, generate enough revenue, and attain consistently profitable operations. Although the current
global pandemic related to the coronavirus (Covid-19) has affected our operations, particularly in supply chain, we now believe that this
is expected to be an ongoing issue and our working capital assumptions reflect this new reality. The Company cannot currently quantify
the uncertainty related to the pandemic and its effects on our customers in the coming quarters. We have analyzed our cash flow under
&#8220;stress test&#8221; conditions and have determined that we have sufficient liquid assets on hand to maintain operations for at least
twelve months from the date of this report. A notable recent success is the approval of the Company for &#8220;bonding&#8221; in the amount
of approximately $8 million for an upcoming major project.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company was successful in securing a loan of $<span id="xdx_909_eus-gaap--SecuredDebt_iI_c20211231_zeBgNGApH6Jh" title="Secured loan"><ix:nonFraction name="us-gaap:SecuredDebt" contextRef="AsOf2021-12-31" format="ixt:numdotdecimal" decimals="0" unitRef="USD">1,410,270</ix:nonFraction></span>
during the second quarter of 2020 from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#8217;s
cash reserves. This loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free. The Company has also
been successful in increasing its working capital surplus after receiving proceeds from the 2021 Offering of $4,500,000 and more recently,
in the first quarter of 2022, receiving net proceeds of approximately $<span id="xdx_90B_eus-gaap--ProceedsFromOtherDebt_c20210101__20211231_zlCk26AbMYm1" title="Net proceeds bebt"><ix:nonFraction name="us-gaap:ProceedsFromOtherDebt" contextRef="From2021-01-01to2021-12-31" format="ixt:numdotdecimal" decimals="0" unitRef="USD">5,500,000</ix:nonFraction></span> from the successful takedown of the Company&#8217;s &#8220;shelf
registration&#8221; S3. This gives us the capital required to fund the fundamental business changes that we undertook in the last quarter
of 2020, further changes throughout 2021 and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue, and
re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and profitability and
focusing product strategy on opportunities that are likely to bear results in the relatively short term. During 2021, management took
further significant actions including reorganizing our engineering and technical teams and selectively improving organizational efficiency
to effectively grow the business as the expected order flow resumes in 2022. Upon completion of the 2022 Offering, management has raised
sufficient working capital to meet its needs for the next 12-months without the need to raise further capital. Since the advent of the
Covid-19 pandemic, the Company has experienced a significant slowdown in closing new projects due to cautious actions by current and potential
clients. We continue to be successful in identifying new business opportunities and are focused on re-establishing a backlog of projects.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Management believes that, at this time, the conditions
in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including a $5.5M injection of funds from a sale of securities, significant recent orders and the overall stabilization of the business
indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve months from
the issuance of this report. We continue executing the plan to grow our business and achieve profitability without the requirement to
raise additional capital for existing operations for 2022 although we may do so to fund selective opportunities that may arise. Management
has extensively evaluated our requirements for the next 12 months and has determined that the Company currently has sufficient cash to
operate for at least that period.</p>

announced that Mr. Arcaini would retire from these positions, effective as of September 1, 2020 (the &#8220;CEO Transition&#8221;). In
order to facilitate a transition of his duties, the Company and Mr. Arcaini entered into a separation agreement which became effective
as of July 10, 2020 (the &#8220;Separation Agreement&#8221;). Pursuant to the Separation Agreement, Mr. Arcaini&#8217;s employment with
the Company ended on September 1, 2020 and he will receive separation payments over a 36-month period equal to his base salary plus $<span id="xdx_90F_ecustom--AdditionalCompensationToBePaidInSeparationPayments_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Compensation to be paid in addition to base salary in separation payments"><ix:nonFraction name="duot:AdditionalCompensationToBePaidInSeparationPayments" contextRef="AsOf2020-07-10_srt_ChiefExecutiveOfficerMember" format="ixt:numdotdecimal" decimals="0" scale="0" unitRef="USD">75,000</ix:nonFraction></span>

the Company. The Corporate Governance and Nominating Committee did not submit Mr. Arcaini for re-election as a director and on November
19, 2020 at the Annual Shareholders meeting a new non-Executive Chairman was appointed.</p>

meaning of Rule 16b-3 promulgated under the Exchange Act and an &#8220;outside director&#8221; within the meaning of Code Section 162(m).
Among other things, the Compensation Committee has complete discretion, subject to the express limits of the 2021 Plan, to determine the
directors, employees and nonemployee consultants to be granted an award, the type of award to be granted, the terms and conditions of
the award, the form of payment to be made and/or the number of shares of Common Stock subject to each award, the exercise price of each
option and base price of each stock appreciation right (&#8220;SAR&#8221;), the term of each award, the vesting schedule for an award,
whether to accelerate vesting, the value of the Common Stock underlying the award, and the required withholding, if any. The Compensation
Committee may amend, modify or terminate any outstanding award, provided that the participant&#8217;s consent to such action is required
if the action would impair the participant&#8217;s rights or entitlements with respect to that award. The Compensation Committee is also
authorized to construe the award agreements and may prescribe rules relating to the 2021 Plan. Notwithstanding the foregoing, the Compensation
Committee does not have any authority to grant or modify an award under the 2021 Plan with terms or conditions that would cause the grant,
vesting or exercise thereof to be considered nonqualified &#8220;deferred compensation&#8221; subject to Code Section 409A.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>&#160;</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The following is a general summary of the federal
income tax consequences under current U.S. tax law to the Company and to participants in the 2021 Plan who are individual citizens or
residents of the United States for federal income tax purposes (&#8220;U.S. Participants&#8221;) of stock options, stock appreciation
rights, restricted stock, performance shares, performance units, restricted stock units, distribution equivalent rights and unrestricted
stock. It does not purport to cover all of the special rules including special rules relating to limitations on the ability of the Company
to deduct the amounts for federal income tax purposes of certain compensation, special rules relating to deferred compensation, golden
parachutes, participants subject to Section 16(b) of the Exchange Act or the exercise of a stock option with previously acquired shares
of the Company&#8217;s Common Stock. For purposes of this summary, it is assumed that U.S. Participants will hold their shares of the
Company&#8217;s Common Stock received under the 2021 Plan as capital assets within the meaning of Section 1221 of the Code. In addition,
this summary does not address the non-U.S. state or local income or other tax consequences, or any U.S. federal non-income tax consequences,
inherent in the acquisition, ownership, vesting, exercise, termination or disposition of an award under the 2021 Plan or shares of the
Company&#8217;s Common Stock issued pursuant thereto. All participants are urged to consult with their own tax advisors concerning the
tax consequences to them of an award under the 2021 Plan or shares of the Company&#8217;s Common Stock issued thereto pursuant to the
2021 Plan.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">A U.S. Participant does not recognize taxable income
upon the grant of a NQSO or an ISO. Upon the exercise of a NQSO, the U.S. Participant recognizes ordinary income in an amount equal to
the excess, if any, of the fair market value of the shares acquired on the date of exercise over the exercise price paid therefor under
the NQSO, and the Company will generally be entitled to a deduction for such amount at that time. If the U.S. Participant later sells
shares acquired pursuant to the exercise of a NQSO, the U.S. Participant recognizes long-term or short-term capital gain or loss, depending
on the period for which the shares were held. Long-term capital gain is generally subject to more favorable tax treatment than ordinary
income or short-term capital gain. Upon the exercise of an ISO, the U.S. Participant does not recognize taxable income. If the U.S. Participant
disposes of the shares acquired pursuant to the exercise of an ISO more than two years after the date of grant and more than one year
after the transfer of the shares to the U.S. Participant, the U.S. Participant recognizes long-term capital gain or loss, and the Company
will not be entitled to a deduction. However, if the U.S. Participant disposes of such shares prior to the end of the required holding
period, all or a portion of the gain is treated as ordinary income and the Company is generally entitled to deduct such amount. In addition
to the tax consequences described above, a U.S. Participant may be subject to the alternative minimum tax, which is payable to the extent
it exceeds the U.S. Participant&#8217;s regular tax. For this purpose, upon the exercise of an ISO, the excess of the fair market value
of the shares over the exercise price paid therefor under the ISO is a preference item for alternative minimum taxable income determination
purposes. In addition, the U.S. Participant&#8217;s basis in such shares is increased by such excess for purposes of computing the gain
or loss on the disposition of the shares for alternative minimum tax purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">A U.S. Participant does not recognize taxable income
upon the grant of an SAR. The U.S. Participant has ordinary compensation income upon exercise of the SAR equal to the increase in the
value of the underlying shares, and the Company will generally be entitled to a deduction for such amount.</p>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">Certain provisions of Florida law, the Articles of Incorporation and our
Bylaws contain provisions that could have the effect of delaying, deferring, or discouraging another party from acquiring control of us.
These provisions, which are summarized below, may have the effect of discouraging coercive takeover practices and inadequate takeover
bids. The provisions are also designed, in part, to encourage persons seeking to acquire control of us to first negotiate with our Board
of Directors. We believe that the benefits of increased protection of our potential ability to negotiate with any unfriendly or unsolicited
acquiror outweighs the disadvantage of discouraging a proposal to acquire us because negotiation of these proposals could result in an
improvement of their terms.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0"><B><I>Anti-Takeover Statute</I></B></P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">As a Florida corporation, we are subject to certain anti-takeover provisions
that apply to public corporations under Florida law. Pursuant to Section 607.0901 of the Act, a publicly held Florida corporation, under
certain circumstances, may not engage in a broad range of business combinations or other extraordinary corporate transactions with an
interested shareholder without the approval of the holders of two-thirds of the voting shares of the corporation (excluding shares held
by the interested shareholder).</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">An interested shareholder is defined as a person who together with affiliates
and associates beneficially owns more than 15% of a corporation&rsquo;s outstanding voting shares. We have not made an election in our
Articles of Incorporation to opt out of Section 607.0901.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">In addition, we are subject to Section 607.0902 of the Act which prohibits
the voting of shares in a publicly-held Florida corporation that are acquired in a control-share acquisition unless (i) our board of directors
approved such acquisition prior to its consummation or (ii) after such acquisition, in lieu of prior approval by our board of directors,
the holders of a majority of the corporation&rsquo;s voting shares, exclusive of shares owned by officers of the corporation, employee
directors or the acquiring party, approve the granting of voting rights as to the shares acquired in the control-share acquisition. A
control-share acquisition is defined as an acquisition that immediately thereafter entitles the acquiring party to 20% or more of the
total voting power in an election of directors.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">Our Bylaws provide that, at a meeting of the shareholders called expressly
for that purpose, any director or the entire Board of Directors may be removed, with or without cause, by a vote of the holders of a majority
of the shares of each class or series of voting stock present in person or by proxy then entitled to vote at an election of directors.
Board vacancies and newly-created directorships resulting from (i) an increase in the authorized number of directors, (ii) death, (iii)
resignation, (iv) retirement, (v) disqualification, or (vi) removal from office, may be filled by a majority vote of the remaining directors
then in office, although less than a quorum, or by the sole remaining director, and each director so chosen shall hold office until the
next annual meeting of shareholders and until such director&rsquo;s successor shall have been duly elected and qualified.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">Our Bylaws establish advance notice procedures with regard to a shareholder&rsquo;s
ability to call a special meeting as well to shareholder proposals relating to the nomination of candidates for election as directors
or new business to be brought before meetings of our shareholders. These procedures provide that notice of shareholder proposals must
be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, for a shareholder
proposal to be timely, notice must be received at our principal executive offices not less than 120 days nor more than 150 days prior
to the first anniversary of the date the Company released its proxy materials to its shareholders for the prior year&rsquo;s annual meeting
of shareholders or any longer period provided by applicable law. Our Bylaws specify the requirements as to form and content of all shareholders&rsquo;
notices. These requirements may preclude shareholders from bringing matters before the shareholders at an annual or special meeting.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">The Board of Directors is authorized to provide, out of the unissued shares
of Preferred Stock, a series of Preferred Stock and, with respect to each such series, to fix the number of shares constituting such series,
and the designation of such series, the voting and other powers (if any) of the shares of such series, and the preferences and any relative,
participating, optional or other special rights and any qualifications, limitations or restrictions thereof, of the shares of such series.
The powers, preferences and relative, participating, optional and other special rights of such series of Preferred Stock, and the qualifications,
limitations or restrictions thereof, may differ from those of any and all other series of preferred Stock at any time outstanding. The
powers and rights of any series of Preferred Stock may be superior to, or otherwise limit, the rights and powers of the Common Stock.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0"><I>Authorized but Unissued Shares</I></P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">Our authorized but unissued shares of Common Stock and Preferred Stock
are available for future issuance without stockholder approval.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">The foregoing provisions will make it more difficult for our existing stockholders
to replace our Board of Directors as well as for another party to obtain control of the Company by replacing our Board of Directors. Since
our Board of Directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing
stockholders or another party to effect a change in management. In addition, the authorization of blank check Preferred Stock makes it
possible for our Board of Directors to issue Preferred Stock with voting or other rights or preferences that could impede the success
of any attempt to change the control of the Company. The existence of authorized but unissued shares of Common Stock and Preferred Stock
could render more difficult or discourage an attempt to obtain control of a majority of our Common Stock by means of a proxy contest,
tender offer, merger or otherwise.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">These provisions are intended to enhance the likelihood of continued stability
in the composition of the Board of Directors and its policies and to discourage certain types of transactions that may involve an actual
or threatened acquisition of the Company. These provisions are also designed to reduce our vulnerability to an unsolicited acquisition
proposal and to discourage certain tactics that may be used in proxy rights. However, such provisions could have the effect of discouraging
others from making tender offers for our shares and may have the effect of deterring hostile takeovers or delaying changes in control
of the Company or our management. As a consequence, these provisions also may inhibit fluctuations in the market price of our stock that
could result from actual or rumored takeover attempts.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0"><B>Choice of Forum</B></P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">The Articles of Incorporation provide that the Circuit Court for Duval
County (or the appropriate Florida federal court) shall be the sole and exclusive forum for (i) any derivative action or proceeding brought
on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director or officer (or affiliate
of any of the foregoing) of the Company to the Company or the Company&rsquo;s shareholders, (iii) any action asserting a claim arising
pursuant to any provision of the Florida Statutes or the Articles of Incorporation or Bylaws, or (iv) any other action asserting a claim
arising under, in connection with, and governed by the internal affairs doctrine. This provision would not apply to suits brought to enforce
a duty or liability created by the Exchange Act. Furthermore, Section&nbsp;22 of the Securities Act of 1933, as amended (the &ldquo;<B>Securities
Act</B>&rdquo;), creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both
state and federal courts have jurisdiction to entertain such claims.&nbsp;</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">These choice of forum provisions may limit a stockholder&rsquo;s ability
to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees,
which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision to be
inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions,
which could harm our business, results of operations, and financial condition.</P>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos Technologies Group, Inc. (the &#8220;Company&#8221;),
through its operating subsidiaries, Duos Technologies, Inc. (&#8220;Duos&#8221;) and TrueVue360, Inc. (&#8220;TrueVue360&#8221;) (collectively
the &#8220;Company&#8221;), develops and deploys vision based analytical technology solutions that will help to transform precision railroading,
logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#8220;AI&#8221;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Through September 30, 2021, the Company also provided
professional and consulting services for large data centers and had developed a system for the automation of asset information marketed
as DcVue&#8482;. The Company had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing
teams. DcVue was based upon the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license
to our customers as a licensed software product.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in
conformity with accounting principles generally accepted in the United States of America requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosures 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 may
differ from these estimates. The most significant estimates in the accompanying consolidated financial statements include the
allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates
of net contract revenues and the total estimated costs to determine progress towards contract completion, estimates of the valuation
of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based
awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these estimates.</p>

Standards Update (&#8220;ASU&#8221;) 2014-89, Revenue from Contracts with Customers (&#8220;ASC 606&#8221;), that affects the timing of
when certain types of revenues will be recognized. The basic principles in ASC 606 include the following: a contract with a customer creates
distinct unrecognized contract assets and performance obligations, satisfaction of a performance obligation creates revenue, and a performance
obligation is satisfied upon transfer of control to a good or service to a customer.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Revenue is recognized by evaluating our revenue contracts

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For revenues related to technology systems, the
Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimated costs
to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding
amount of revenue to recognize.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_Aci_Pg63"/>Accordingly, the Company
now bases its revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance
does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192. (see Note 9)</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>




<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract
labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged
to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in &#8220;contract
assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract liabilities&#8221;.
However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Maintenance and technical support services are provided
on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided
outside of a maintenance contract are on an as-requested basis, and revenue is recognized as the services are provided. Revenue for maintenance
and technical support provided on an extended-term basis is recognized ratably over the term of the contract.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For sales arrangements that do not involve multiple
elements such as professional services, which are of short-term duration, revenues are recognized when services are completed.</p>

business in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605-25 which addresses
revenue recognition for the software industry. The general criteria for revenue recognition under ASC 985-605 for our Company, which sells
software licenses, which do not require any significant modification or customization, is that revenue is recognized when persuasive evidence
of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable.</p>

that incorporate artificial intelligence (AI) in the form of predetermined algorithms to provide important operating information to the

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Arrangements with customers may involve multiple elements
including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project
is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple elements
may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while
other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for
a multiple element arrangement is as follows:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each element is accounted for separately when each
element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple
element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined
with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of
revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and
software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling
price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based
on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase
maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue
recognition purposes.</p>

Board (&#8220;FASB&#8221;) issued ASU 2016-02, Leases (Topic 842). The updated guidance requires lessees to recognize right-of-use (&#8220;ROU&#8221;)
assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and non-lease
components in a contract in accordance with the new revenue guidance in ASC 606. This guidance is effective for interim and annual reporting

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company adopted this guidance effective January
1, 2019, using the modified retrospective method, whereby a cumulative effect adjustment was made as of the date of initial application.
The Company also applied the package of practical expedients to leases that commenced before the effective date whereby the Company elected
to not reassess the following: (i) whether any expired or existing contracts contain leases and (ii) initial direct costs for any existing
leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance
sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases
that contain both lease and non-lease components as a single lease component.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For contracts entered into on or after the effective
date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company&#8217;s assessment
is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially
all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.</p>

the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>&#160;</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As reflected in the accompanying consolidated financial
statements, the Company had a net loss of $<span id="xdx_907_eus-gaap--NetIncomeLoss_iN_pp0p0_di_c20210101__20211231_zk1fPOme03j" title="Net income">6,008,901</span> for the year ended December 31, 2021. During the same period, cash used in operating
activities was $<span id="xdx_906_eus-gaap--NetCashProvidedByUsedInOperatingActivities_iN_pp0p0_di_c20210101__20211231_znDv9XJ6lpG2" title="Net cash used in operations">6,579,378</span>. The negative working capital and accumulated deficit as of December 31, 2021 were $<span id="xdx_907_ecustom--WorkingCapitalDeficit_iNI_pp0p0_di_c20211231_zBTyrPZlsZPe" title="Working capital deficit">651,381</span> and $<span id="xdx_907_eus-gaap--RetainedEarningsAccumulatedDeficit_iNI_pp0p0_di_c20211231_zX4jDnMWSKN6" title="Accumulated deficit">45,497,051</span>,
respectively. In previous financial reports, the Company had raised substantial doubt about continuing as a going concern. This was principally
due to a lack of working capital prior to an underwritten offering which was completed during the first quarter of 2022 (the &#8220;2022
Offering&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously noted, the Company raised $4,500,000
from existing shareholders through the issuance of Series C Convertible Preferred Stock. Although additional investment is not assured,
the Company is comfortable that it would be able to raise sufficient capital to support expanded operations based on an anticipated increase
in business activity. In the long run, the continuation of the Company as a going concern is dependent upon the ability of the Company
to continue executing the plan described above, generate enough revenue, and attain consistently profitable operations. Although the current
global pandemic related to the coronavirus (Covid-19) has affected our operations, particularly in supply chain, we now believe that this
is expected to be an ongoing issue and our working capital assumptions reflect this new reality. The Company cannot currently quantify
the uncertainty related to the pandemic and its effects on our customers in the coming quarters. We have analyzed our cash flow under
&#8220;stress test&#8221; conditions and have determined that we have sufficient liquid assets on hand to maintain operations for at least
twelve months from the date of this report. A notable recent success is the approval of the Company for &#8220;bonding&#8221; in the amount
of approximately $8 million for an upcoming major project.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company was successful in securing a loan of $<span id="xdx_909_eus-gaap--SecuredDebt_iI_c20211231_zeBgNGApH6Jh" title="Secured loan">1,410,270</span>
during the second quarter of 2020 from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#8217;s
cash reserves. This loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free. The Company has also
been successful in increasing its working capital surplus after receiving proceeds from the 2021 Offering of $4,500,000 and more recently,
in the first quarter of 2022, receiving net proceeds of approximately $<span id="xdx_90B_eus-gaap--ProceedsFromOtherDebt_c20210101__20211231_zlCk26AbMYm1" title="Net proceeds bebt">5,500,000</span> from the successful takedown of the Company&#8217;s &#8220;shelf
registration&#8221; S3. This gives us the capital required to fund the fundamental business changes that we undertook in the last quarter
of 2020, further changes throughout 2021 and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue, and
re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and profitability and
focusing product strategy on opportunities that are likely to bear results in the relatively short term. During 2021, management took
further significant actions including reorganizing our engineering and technical teams and selectively improving organizational efficiency
to effectively grow the business as the expected order flow resumes in 2022. Upon completion of the 2022 Offering, management has raised
sufficient working capital to meet its needs for the next 12-months without the need to raise further capital. Since the advent of the
Covid-19 pandemic, the Company has experienced a significant slowdown in closing new projects due to cautious actions by current and potential
clients. We continue to be successful in identifying new business opportunities and are focused on re-establishing a backlog of projects.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>




<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Management believes that, at this time, the conditions
in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including a $5.5M injection of funds from a sale of securities, significant recent orders and the overall stabilization of the business
indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve months from
the issuance of this report. We continue executing the plan to grow our business and achieve profitability without the requirement to
raise additional capital for existing operations for 2022 although we may do so to fund selective opportunities that may arise. Management
has extensively evaluated our requirements for the next 12 months and has determined that the Company currently has sufficient cash to
operate for at least that period.</p>

Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.</p></div>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"><b>&#160;</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On April 1, 2018, the Company entered into an employment
agreement (the &#8220;Arcaini Employment Agreement&#8221;) with Gianni B. Arcaini, pursuant to which Mr. Arcaini served as Chief Executive
Officer and Chairman of the Board of Directors of the Company. Under the Arcaini Employment Agreement, Mr. Arcaini was paid an annual
salary of $<span id="xdx_909_eus-gaap--OfficersCompensation_pp0p0_c20180401__20180430__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zZbjm3bfNyo2" title="Annual salary">249,260</span> and an annual car allowance of $<span id="xdx_90A_ecustom--AnnualCarAllowance_c20180401__20180430__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Annual Car allowance">18,000</span>. In addition, as incentive-based compensation, Mr. Arcaini was entitled to <span id="xdx_90F_ecustom--PercentageOfGrossRevenue_dp_c20180401__20180430__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_z1ZZ8vpB4Nu" title="Percentage of gross revenue">1</span>%
of annual gross revenues of the Company and its subsidiaries. The Arcaini Employment Agreement had an initial term through March 31, 2020,
subject to renewal for successive one-year terms unless either party gave notice of that party&#8217;s election to not renew to the other
at least 60 days prior to the expiration of the then-current term. The Arcaini Employment Agreement was approved by the Compensation Committee.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously disclosed, on July 10, 2020, the Company
announced that Mr. Arcaini would retire from these positions, effective as of September 1, 2020 (the &#8220;CEO Transition&#8221;). In
order to facilitate a transition of his duties, the Company and Mr. Arcaini entered into a separation agreement which became effective
as of July 10, 2020 (the &#8220;Separation Agreement&#8221;). Pursuant to the Separation Agreement, Mr. Arcaini&#8217;s employment with
the Company ended on September 1, 2020 and he will receive separation payments over a 36-month period equal to his base salary plus $<span id="xdx_90F_ecustom--AdditionalCompensationToBePaidInSeparationPayments_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Compensation to be paid in addition to base salary in separation payments">75,000</span>
as well as certain limited health and life insurance benefits. The Separation Agreement also contains confidentiality, non-disparagement
and non-solicitation covenants and a release of claims by Mr. Arcaini who continued to serve as Chairman of the Board of Directors of
the Company. The Corporate Governance and Nominating Committee did not submit Mr. Arcaini for re-election as a director and on November
19, 2020 at the Annual Shareholders meeting a new non-Executive Chairman was appointed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_Aci_Pg75"/>In accordance with the Separation
Agreement, the Company will pay to Mr. Arcaini the total sum of $<span id="xdx_90E_ecustom--OnetimeChargeToBePaidOverThirtySixMonthTermOfSeparationAgreement_iI_pp0p0_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zkrOMK7xdcqj" title="One-time charge which will be amortized in equal amounts over the 36-month term of the separation agreement">747,788</span>. Notwithstanding the foregoing, the status of Mr. Arcaini as
a &#8220;Specified Employee&#8221; as defined in Internal Revenue Code Section 409A has the effect of delaying any payments to Mr. Arcaini
under the Separation Agreement for six months after the Separation Date. On March 1, 2021, the Company paid to Mr. Arcaini a lump-sum
amount equal to the first six months of payments, or $<span id="xdx_905_ecustom--PaymentOneOfSeparationAgreement_iI_pp0p0_c20210302__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zHr3xRScdUFc" title="Lump sum payment owed under separation agreement">124,631</span>, owed to Mr. Arcaini and the Company will continue to pay him in semi-monthly
installments for 30 months thereafter, as contemplated in Mr. Arcaini&#8217;s Separation Agreement. The remaining balance of approximately

In addition, the Company
will pay one-half of Mr. Arcaini&#8217;s current life insurance premiums for 36 months of approximately $<span id="xdx_90E_ecustom--PaymentTwoSeparationAgreementForLifeInsurance_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Current life insurance">1,200</span> per month and provide and

The Company made payment of his attorneys&#8217;
fees for legal work associated with the negotiation and drafting of the Separation Agreement of approximately $<span id="xdx_90C_eus-gaap--LegalFees_c20200701__20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Legal Fees">17,000</span>.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The following is a general summary of the federal
income tax consequences under current U.S. tax law to the Company and to participants in the 2021 Plan who are individual citizens or
residents of the United States for federal income tax purposes (&#8220;U.S. Participants&#8221;) of stock options, stock appreciation
rights, restricted stock, performance shares, performance units, restricted stock units, distribution equivalent rights and unrestricted
stock. It does not purport to cover all of the special rules including special rules relating to limitations on the ability of the Company
to deduct the amounts for federal income tax purposes of certain compensation, special rules relating to deferred compensation, golden
parachutes, participants subject to Section 16(b) of the Exchange Act or the exercise of a stock option with previously acquired shares
of the Company&#8217;s Common Stock. For purposes of this summary, it is assumed that U.S. Participants will hold their shares of the
Company&#8217;s Common Stock received under the 2021 Plan as capital assets within the meaning of Section 1221 of the Code. In addition,
this summary does not address the non-U.S. state or local income or other tax consequences, or any U.S. federal non-income tax consequences,
inherent in the acquisition, ownership, vesting, exercise, termination or disposition of an award under the 2021 Plan or shares of the
Company&#8217;s Common Stock issued pursuant thereto. All participants are urged to consult with their own tax advisors concerning the
tax consequences to them of an award under the 2021 Plan or shares of the Company&#8217;s Common Stock issued thereto pursuant to the
2021 Plan.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">A U.S. Participant does not recognize taxable income
upon the grant of a NQSO or an ISO. Upon the exercise of a NQSO, the U.S. Participant recognizes ordinary income in an amount equal to
the excess, if any, of the fair market value of the shares acquired on the date of exercise over the exercise price paid therefor under
the NQSO, and the Company will generally be entitled to a deduction for such amount at that time. If the U.S. Participant later sells
shares acquired pursuant to the exercise of a NQSO, the U.S. Participant recognizes long-term or short-term capital gain or loss, depending
on the period for which the shares were held. Long-term capital gain is generally subject to more favorable tax treatment than ordinary
income or short-term capital gain. Upon the exercise of an ISO, the U.S. Participant does not recognize taxable income. If the U.S. Participant
disposes of the shares acquired pursuant to the exercise of an ISO more than two years after the date of grant and more than one year
after the transfer of the shares to the U.S. Participant, the U.S. Participant recognizes long-term capital gain or loss, and the Company
will not be entitled to a deduction. However, if the U.S. Participant disposes of such shares prior to the end of the required holding
period, all or a portion of the gain is treated as ordinary income and the Company is generally entitled to deduct such amount. In addition
to the tax consequences described above, a U.S. Participant may be subject to the alternative minimum tax, which is payable to the extent
it exceeds the U.S. Participant&#8217;s regular tax. For this purpose, upon the exercise of an ISO, the excess of the fair market value
of the shares over the exercise price paid therefor under the ISO is a preference item for alternative minimum taxable income determination
purposes. In addition, the U.S. Participant&#8217;s basis in such shares is increased by such excess for purposes of computing the gain
or loss on the disposition of the shares for alternative minimum tax purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On August 1, 2012, the Company entered into an independent
contractor master services agreement (the &#8220;Services Agreement&#8221;) with Luceon, LLC, a Florida limited liability company, owned
by our former Chief Technology Officer, David Ponevac.&#160;The Services Agreement provided that Luceon would provide support services
including management, coordination or software development services and related services to duos. In January 2019, additional services
were contracted with Luceon for TrueVue360&#8482; primarily for software development through the provision of 7 additional full-time
contractors located in Slovakia at a cost of $<span id="xdx_900_eus-gaap--RelatedPartyCosts_c20190101__20190131_z8qwvRUtaeik">16,250</span> for January initially, rising to $<span id="xdx_904_eus-gaap--RelatedPartyCosts_c20190201__20190228_zRKeyyZr2Gra">25,583</span> after fully staffed, per month starting
February 2019. This was in addition to the existing contract of $<span id="xdx_902_eus-gaap--RelatedPartyCosts_c20190601__20190630__srt--ProductOrServiceAxis__custom--ContractorsMember_zcn50ms3Mkkj">7,480</span> per month for duos for 4 full-time contractors which increased
to $<span id="xdx_901_eus-gaap--RelatedPartyCosts_c20190601__20190630_zohq2TurrMa1">8,231</span> per month in June of 2019. During 2020 efforts in reducing cost, Luceon reduced its staff for the TrueVue360 software development
team from a staff of 7 to 3 full-time employees at a cost of $11,666 per month starting June 1, 2020. As of January 1, 2021, the Company
no longer records activities in TrueVue360 and has combined billings for a total of $<span id="xdx_905_eus-gaap--AccountsPayableRelatedPartiesCurrentAndNoncurrent_iI_c20210102_z8qyaelKzoz6" title="Accounts payable">20,986</span> per month. For the nine months ended December
31, 2021 and 2020, the total amount expensed is $<span id="xdx_909_eus-gaap--RelatedPartyCosts_c20210101__20211231_z565Cpll9mQl" title="Related party cost">93,422</span> and $<span id="xdx_906_eus-gaap--RelatedPartyCosts_c20200101__20201231_z00kTsJicTUi">335,334</span>, respectively. The Company had no open accounts payable with Luceon
at December 31, 2021. On May 14, 2021, the Company formally ended its relationship with Luceon in concert with the resignation of our
Chief Technology Officer and as such there is no longer a related party relationship.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos Technologies Group, Inc. (the &#8220;Company&#8221;),
through its operating subsidiaries, Duos Technologies, Inc. (&#8220;Duos&#8221;) and TrueVue360, Inc. (&#8220;TrueVue360&#8221;) (collectively
the &#8220;Company&#8221;), develops and deploys vision based analytical technology solutions that will help to transform precision railroading,
logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#8220;AI&#8221;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Through September 30, 2021, the Company also provided
professional and consulting services for large data centers and had developed a system for the automation of asset information marketed
as DcVue&#8482;. The Company had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing
teams. DcVue was based upon the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license
to our customers as a licensed software product.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.</p>

conformity with accounting principles generally accepted in the United States of America requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosures 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 may
differ from these estimates. The most significant estimates in the accompanying consolidated financial statements include the
allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates
of net contract revenues and the total estimated costs to determine progress towards contract completion, estimates of the valuation
of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based
awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these estimates.</p>

undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that
long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison
of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.</p>

when certain types of revenues will be recognized. The basic principles in ASC 606 include the following: a contract with a customer creates
distinct unrecognized contract assets and performance obligations, satisfaction of a performance obligation creates revenue, and a performance
obligation is satisfied upon transfer of control to a good or service to a customer.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For revenues related to technology systems, the
Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimated costs
to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding
amount of revenue to recognize.</p>

<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_Aci_Pg63"/>Accordingly, the Company
now bases its revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance
does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192. (see Note 9)</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>




<p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract
labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged
to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in &#8220;contract
assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract liabilities&#8221;.
However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided
outside of a maintenance contract are on an as-requested basis, and revenue is recognized as the services are provided. Revenue for maintenance
and technical support provided on an extended-term basis is recognized ratably over the term of the contract.</p>

including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project
is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple elements
may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while
other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for
a multiple element arrangement is as follows:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each element is accounted for separately when each
element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple
element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined
with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of
revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and
software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling
price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based
on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase
maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue
recognition purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In February 2016, the Financial Accounting Standards
Board (&#8220;FASB&#8221;) issued ASU 2016-02, Leases (Topic 842). The updated guidance requires lessees to recognize right-of-use (&#8220;ROU&#8221;)
assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and non-lease
components in a contract in accordance with the new revenue guidance in ASC 606. This guidance is effective for interim and annual reporting
periods beginning after December 15, 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company adopted this guidance effective January
1, 2019, using the modified retrospective method, whereby a cumulative effect adjustment was made as of the date of initial application.
The Company also applied the package of practical expedients to leases that commenced before the effective date whereby the Company elected
to not reassess the following: (i) whether any expired or existing contracts contain leases and (ii) initial direct costs for any existing
leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance
sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases
that contain both lease and non-lease components as a single lease component.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>




<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The adoption of ASU 2016-02 did not materially affect
our consolidated statement of operations or our consolidated statement of cash flows.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For contracts entered into on or after the effective
date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company&#8217;s assessment
is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially
all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.</p>

the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments

of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We plan to adopt this pronouncement

the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2022, and we do not

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.</p></div>

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Duos Technologies Group, Inc. (the &#x201c;Company&#x201d;),
through its operating subsidiaries, Duos Technologies, Inc. (&#x201c;Duos&#x201d;) and TrueVue360, Inc. (&#x201c;TrueVue360&#x201d;) (collectively
the &#x201c;Company&#x201d;), develops and deploys vision based analytical technology solutions that will help to transform precision railroading,
logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#x201c;AI&#x201d;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has built a portfolio of IP and patented
solutions that creates &#x201c;actionable intelligence&#x201d; using two core native platforms called Centraco&#xae; and Praesidium&#x2122;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#x2122; with the objective of focusing the Company&#x2019;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Through September 30, 2021, the Company also provided
professional and consulting services for large data centers and had developed a system for the automation of asset information marketed
as DcVue&#x2122;. The Company had deployed its DcVue software at one beta site. This software was used by Duos&#x2019; consulting auditing
teams. DcVue was based upon the Company&#x2019;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license
to our customers as a licensed software product.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The preparation of financial statements in
conformity with accounting principles generally accepted in the United States of America requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosures 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 may
differ from these estimates. The most significant estimates in the accompanying consolidated financial statements include the
allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates
of net contract revenues and the total estimated costs to determine progress towards contract completion, estimates of the valuation
of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based
awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these estimates.&lt;/p&gt;

In all cases,
there are no minimum contract values stated. Each contract covers an agreement to deliver a rail inspection portal which, once accepted,
must be paid in full, with 30% or more being due and payable prior to delivery. The balances of the contracts are for service and maintenance
which is paid annually in advance with revenues recorded ratably over the contract period. Each of the customers referenced has the following
termination provisions:&lt;/p&gt;

either party breach any of its obligations under the agreement with the Company. The other party may terminate the agreement effective
fifteen (15) Business Days following notice from the non-defaulting party, if the non-performance has not been cured within such period,
and without prejudice to damages that could be claimed by the non-defaulting party. Either party may terminate the agreement if the other
party becomes unable to pay its debts in the ordinary course of business; goes into liquidation (other than for the purpose of a genuine
amalgamation or restructuring); has a receiver appointed over all or part of its assets; enters into a composition or voluntary arrangement
with its creditors; or any similar event occurs in any jurisdiction, all to the extent permitted by law.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

basis of such default, the defaulting party has not rectified such default to the reasonable satisfaction of the non-defaulting party.
Failure to perform due to a force majeure condition shall not be considered a material default under the agreement.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company follows Accounting Standards Codification
(&#x201c;ASC&#x201d;) 820, &#x201c;Fair Value Measurements and Disclosures&#x201d; (&#x201c;ASC 820&#x201d;), for assets and liabilities measured
at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted
accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure
about such fair value measurements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg61"/&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;ASC&#160;820 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, ASC&#160;820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the
use of unobservable inputs.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;These inputs are prioritized below:&#160;&lt;/p&gt;

  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company analyzes all financial instruments with
features of both liabilities and equity under the Financial Accounting Standard Board&#x2019;s (&#x201c;FASB&#x201d;) accounting standard
for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level
of input that is significant to the fair value measurement.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The estimated fair value of certain financial instruments,
including accounts receivable, prepaid expense, accounts payable, accrued expenses and notes payable are carried at historical cost basis,

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accounts receivable are stated at estimated net realizable
value. Accounts receivable are comprised of balances due from customers net of estimated allowances for uncollectible accounts. In determining
the collections on accounts, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances.
The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required
allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based
on how recently payments have been received from customers.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Inventory consists primarily of spare parts and consumables
to be used in the production of our technology systems or in connection with maintenance agreements with customers. Inventory is stated
at the lower of cost or net realizable value. Inventory cost is primarily determined using the weighted average cost method.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Property and equipment are stated at cost, less

When assets are sold or retired, their costs and accumulated depreciation are eliminated from the accounts
and any gain or loss resulting from their disposal is included in the statement of operations. Leasehold improvements are expensed
over the shorter of the term of our lease or their useful lives.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Software development costs incurred prior to
establishing technological feasibility are charged to operations and included in research and development costs. The technological feasibility
of a software product is established when the Company has completed all planning, designing, coding, and testing activities that are necessary
to establish that the product meets its design specifications, including functionality, features, and technical performance requirements.
Software development costs incurred after establishing technological&#160;feasibility for software sold as a perpetual license, as defined
within ASC 985-20 (Software &#x2013; Costs of Software to be sold, Leased, or Marketed) are capitalized and amortized on a product-by-product

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company evaluates the recoverability of its property,
equipment, and other long-lived assets in accordance with FASB ASC 360-10-35-15 &#x201c;Impairment or Disposal of Long-Lived Assets&#x201d;,
which requires recognition of impairment of long-lived assets in the event the net book value of such assets exceed the estimated future
undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that
long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison
of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.&lt;/p&gt;

made.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Technology Systems&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As of January 1, 2018, the Company adopted Accounting
Standards Update (&#x201c;ASU&#x201d;) 2014-89, Revenue from Contracts with Customers (&#x201c;ASC 606&#x201d;), that affects the timing of
when certain types of revenues will be recognized. The basic principles in ASC 606 include the following: a contract with a customer creates
distinct unrecognized contract assets and performance obligations, satisfaction of a performance obligation creates revenue, and a performance
obligation is satisfied upon transfer of control to a good or service to a customer.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Revenue is recognized by evaluating our revenue contracts
with customers based on the five-step model under ASC 606:&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"&gt;&lt;tr style="vertical-align: top"&gt;
&lt;td style="width: 20.15pt"/&gt;&lt;td style="width: 18pt"&gt;1.&lt;/td&gt;&lt;td style="text-align: justify"&gt;Identify the contract with the customer;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"&gt;&lt;tr style="vertical-align: top"&gt;
&lt;td style="width: 20.15pt"/&gt;&lt;td style="width: 18pt"&gt;2.&lt;/td&gt;&lt;td style="text-align: justify"&gt;Identify the performance obligations in the contract;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"&gt;&lt;tr style="vertical-align: top"&gt;
&lt;td style="width: 20.15pt"/&gt;&lt;td style="width: 18pt"&gt;3.&lt;/td&gt;&lt;td style="text-align: justify"&gt;Determine the transaction price;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"&gt;&lt;tr style="vertical-align: top"&gt;
&lt;td style="width: 20.15pt"/&gt;&lt;td style="width: 18pt"&gt;4.&lt;/td&gt;&lt;td style="text-align: justify"&gt;Allocate the transaction price to separate performance obligations; and&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"&gt;&lt;tr style="vertical-align: top"&gt;
&lt;td style="width: 20.15pt"/&gt;&lt;td style="width: 18pt"&gt;5.&lt;/td&gt;&lt;td style="text-align: justify"&gt;Recognize revenue when (or as) each performance obligation is satisfied.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For revenues related to technology systems, the
Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimated costs
to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding
amount of revenue to recognize.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg63"/&gt;Accordingly, the Company
now bases its revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#x2019;s performance
does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192. (see Note 9)&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract
labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged
to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in &#x201c;contract
assets&#x201d;. Any billings of customers more than recognized revenues are recorded as a liability in &#x201c;contract liabilities&#x201d;.
However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Technical Support&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Maintenance and technical support services are provided
on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided
outside of a maintenance contract are on an as-requested basis, and revenue is recognized as the services are provided. Revenue for maintenance
and technical support provided on an extended-term basis is recognized ratably over the term of the contract.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales arrangements that do not involve multiple
elements such as professional services, which are of short-term duration, revenues are recognized when services are completed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Consulting Services&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company recognizes revenue from its IT asset management
business in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605-25 which addresses
revenue recognition for the software industry. The general criteria for revenue recognition under ASC 985-605 for our Company, which sells
software licenses, which do not require any significant modification or customization, is that revenue is recognized when persuasive evidence
of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s IT asset management business generates
revenues from three sources: (1) Professional Services (consulting and auditing), (2) Software licensing with optional hardware sales
and (3) Customer Service (training and maintenance support).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales arrangements that do not involve multiple
elements:&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;td style="width: 2pc"/&gt;&lt;td style="width: 2pc"&gt;(1)&lt;/td&gt;&lt;td style="text-align: justify"&gt;Revenues for professional services, which are of short-term duration, are recognized when services are

&lt;td style="width: 2pc"/&gt;&lt;td style="width: 2pc"&gt;(2)&lt;/td&gt;&lt;td style="text-align: justify"&gt;For all periods reflected in this report, software license sales have been one-time sales of a perpetual
license to use our software product and the customer also has the option to purchase third party manufactured handheld devices from us
if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware,
as applicable, to the customer;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;AI Technologies &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has begun to derive revenue from applications
that incorporate artificial intelligence (AI) in the form of predetermined algorithms to provide important operating information to the
users of our systems. The revenue generated from these applications of AI consists of an annual application maintenance fee which will
be recognized ratably over the year, plus fees for the design, development, testing and incorporation of new algorithms into the system
which will be recognized upon completion of each deliverable.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;









&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Multiple Elements&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements with customers may involve multiple elements
including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project
is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple elements
may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while
other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for
a multiple element arrangement is as follows:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Each element is accounted for separately when each
element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple
element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined
with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of
revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and
software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling
price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based
on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase
maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue
recognition purposes.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;
&lt;p id="xdx_84E_ecustom--DeferredRevenuePolicyTextBlock_zVS75l7OXHWh" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_868_zlCUhs69vBTj"&gt;Deferred Revenue&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Deferred revenues represent billings or cash
received in excess of revenue recognizable on service agreements that are not accounted for under the percentage of completion method.
At December 31, 2021 and 2020, the balance of deferred revenue was $&lt;span id="xdx_90C_eus-gaap--DeferredRevenue_iI_pp0p0_c20211231_ziA0NXqLVLHi" title="Deferred Revenue"&gt;596,673&lt;/span&gt; and $&lt;span id="xdx_908_eus-gaap--DeferredRevenue_iI_pp0p0_c20201231_zzbeFh4VYqAk" title="Deferred Revenue"&gt;315,370&lt;/span&gt;, respectively. The amounts will be recorded to
revenue over the next 12 months.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Disaggregation of Revenue &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company is following the guidance of ASC 606-10-55-296
and 297 for disaggregation of revenue. Accordingly, revenue has been disaggregated according to the nature, amount, timing and uncertainty
of revenue and cash flows. We are providing qualitative and quantitative disclosures.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Qualitative:&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company expenses the cost of advertising.
During the years ended December 31, 2021 and 2020, there were &lt;span id="xdx_907_eus-gaap--AdvertisingExpense_do_c20210101__20211231_z1pC4NQtq187" title="Advertising cost"&gt;&lt;span id="xdx_90F_eus-gaap--AdvertisingExpense_do_c20200101__20201231_zx7Y9YVt1Huk"&gt;no&lt;/span&gt;&lt;/span&gt; advertising costs.&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for employee stock-based compensation
in accordance with ASC 718-10, &#x201c;&lt;i&gt;Share-Based Payment&lt;/i&gt;,&#x201d; which requires the measurement and recognition of compensation
expense for all share-based payment awards made to employees and directors including employee stock options, restricted stock units, and
employee stock purchases based on estimated fair values.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Determining Fair Value Under ASC 718-10&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates the fair value of stock options
granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite
service periods of the awards, which is generally the vesting period. The Company&#x2019;s determination of fair value using an option-pricing
model is affected by the stock price as well as assumptions regarding the number of highly subjective variables.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates volatility based upon the historical
stock price of the Company and estimates the expected term for employee stock options using the simplified method for employees and directors
and the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury
securities with similar maturities.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p id="xdx_843_eus-gaap--IncomeTaxPolicyTextBlock_znr79W6Axse9" style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_866_zIsdzMkSxob2"&gt;Income Taxes&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for income taxes in accordance
with the Financial Accounting Standards Board FASB Accounting Standards Codification (&#x201c;ASC&#x201d;) 740, Income Taxes, which requires
the recognition of deferred income taxes for differences between the basis of assets and liabilities for financial statement and income
tax purposes. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either
be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary
to reduce deferred tax assets to the amount expected to be realized.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg67"/&gt;The Company evaluates
all significant tax positions as required by ASC 740. As of December 31, 2021, the Company does not believe that it has taken any positions
that would require the recording of any additional tax liability nor does it believe that there are any unrealized tax benefits that would
either increase or decrease within the next year.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Any penalties and interest assessed by income
taxing authorities are included in operating expenses.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The federal and state income tax returns of the
Company are subject to examination by the IRS and state taxing authorities, generally for three years after they were filed. Tax years
2018, 2019 and 2020 remain open for potential audit.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p id="xdx_843_eus-gaap--EarningsPerSharePolicyTextBlock_zLckanFV7yu5" style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_86E_zSZmUnEWRhXl"&gt;Earnings (Loss) Per Share&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Basic earnings per share (EPS) are computed by dividing
net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is
computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period
and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares
issuable upon the exercise of stock options, stock warrants, convertible debt instruments, convertible preferred stock or other common
stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. At December 31,
2021, there was an aggregate of &lt;span id="xdx_900_eus-gaap--ClassOfWarrantOrRightOutstanding_c20211231_pdd" title="Number of Warrants Outstanding"&gt;1,376,466&lt;/span&gt; outstanding warrants to purchase shares of common stock. At December 31, 2021, there was an

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p id="xdx_845_eus-gaap--LesseeLeasesPolicyTextBlock_z9K2zbqdCUIc" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_867_z35VOsE3Bbe2"&gt;Leases&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In February 2016, the Financial Accounting Standards
Board (&#x201c;FASB&#x201d;) issued ASU 2016-02, Leases (Topic 842). The updated guidance requires lessees to recognize right-of-use (&#x201c;ROU&#x201d;)
assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and non-lease
components in a contract in accordance with the new revenue guidance in ASC 606. This guidance is effective for interim and annual reporting
periods beginning after December 15, 2018.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company adopted this guidance effective January
1, 2019, using the modified retrospective method, whereby a cumulative effect adjustment was made as of the date of initial application.
The Company also applied the package of practical expedients to leases that commenced before the effective date whereby the Company elected
to not reassess the following: (i) whether any expired or existing contracts contain leases and (ii) initial direct costs for any existing
leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance
sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases
that contain both lease and non-lease components as a single lease component.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The adoption of ASU 2016-02 did not materially affect
our consolidated statement of operations or our consolidated statement of cash flows.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For contracts entered into on or after the effective
date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company&#x2019;s assessment
is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially
all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;From time to time, the FASB or other standards setting
bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards
Update (&#x201c;ASU&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In August 2020,
the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We plan to adopt this pronouncement
for our fiscal year beginning January 1, 2022, and we do not expect it to have a material effect on our consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"/&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In May 2021,
the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2022, and we do not
expect it to have a material effect on our consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Management does not believe that any other recently
issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Duos Technologies Group, Inc. (the &#x201c;Company&#x201d;),
through its operating subsidiaries, Duos Technologies, Inc. (&#x201c;Duos&#x201d;) and TrueVue360, Inc. (&#x201c;TrueVue360&#x201d;) (collectively
the &#x201c;Company&#x201d;), develops and deploys vision based analytical technology solutions that will help to transform precision railroading,
logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#x201c;AI&#x201d;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has built a portfolio of IP and patented
solutions that creates &#x201c;actionable intelligence&#x201d; using two core native platforms called Centraco&#xae; and Praesidium&#x2122;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#x2122; with the objective of focusing the Company&#x2019;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Through September 30, 2021, the Company also provided
professional and consulting services for large data centers and had developed a system for the automation of asset information marketed
as DcVue&#x2122;. The Company had deployed its DcVue software at one beta site. This software was used by Duos&#x2019; consulting auditing
teams. DcVue was based upon the Company&#x2019;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license
to our customers as a licensed software product.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s strategy is to deliver operational

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The preparation of financial statements in
conformity with accounting principles generally accepted in the United States of America requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosures 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 may
differ from these estimates. The most significant estimates in the accompanying consolidated financial statements include the
allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates
of net contract revenues and the total estimated costs to determine progress towards contract completion, estimates of the valuation
of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based
awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these estimates.&lt;/p&gt;

either party breach any of its obligations under the agreement with the Company. The other party may terminate the agreement effective
fifteen (15) Business Days following notice from the non-defaulting party, if the non-performance has not been cured within such period,
and without prejudice to damages that could be claimed by the non-defaulting party. Either party may terminate the agreement if the other
party becomes unable to pay its debts in the ordinary course of business; goes into liquidation (other than for the purpose of a genuine
amalgamation or restructuring); has a receiver appointed over all or part of its assets; enters into a composition or voluntary arrangement
with its creditors; or any similar event occurs in any jurisdiction, all to the extent permitted by law.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

basis of such default, the defaulting party has not rectified such default to the reasonable satisfaction of the non-defaulting party.
Failure to perform due to a force majeure condition shall not be considered a material default under the agreement.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company follows Accounting Standards Codification
(&#x201c;ASC&#x201d;) 820, &#x201c;Fair Value Measurements and Disclosures&#x201d; (&#x201c;ASC 820&#x201d;), for assets and liabilities measured
at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted
accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure
about such fair value measurements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg61"/&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;ASC&#160;820 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, ASC&#160;820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the
use of unobservable inputs.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;These inputs are prioritized below:&#160;&lt;/p&gt;

    &lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company analyzes all financial instruments with
features of both liabilities and equity under the Financial Accounting Standard Board&#x2019;s (&#x201c;FASB&#x201d;) accounting standard
for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level
of input that is significant to the fair value measurement.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The estimated fair value of certain financial instruments,
including accounts receivable, prepaid expense, accounts payable, accrued expenses and notes payable are carried at historical cost basis,
which approximates their fair values because of the short-term nature of these instruments.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accounts receivable are stated at estimated net realizable

the collections on accounts, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances.
The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required
allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based
on how recently payments have been received from customers.&lt;/p&gt;

equipment, and other long-lived assets in accordance with FASB ASC 360-10-35-15 &#x201c;Impairment or Disposal of Long-Lived Assets&#x201d;,
which requires recognition of impairment of long-lived assets in the event the net book value of such assets exceed the estimated future
undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that
long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison
of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.&lt;/p&gt;

Standards Update (&#x201c;ASU&#x201d;) 2014-89, Revenue from Contracts with Customers (&#x201c;ASC 606&#x201d;), that affects the timing of
when certain types of revenues will be recognized. The basic principles in ASC 606 include the following: a contract with a customer creates
distinct unrecognized contract assets and performance obligations, satisfaction of a performance obligation creates revenue, and a performance
obligation is satisfied upon transfer of control to a good or service to a customer.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Revenue is recognized by evaluating our revenue contracts

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For revenues related to technology systems, the
Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimated costs
to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding
amount of revenue to recognize.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg63"/&gt;Accordingly, the Company
now bases its revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#x2019;s performance
does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192. (see Note 9)&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract
labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged
to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in &#x201c;contract
assets&#x201d;. Any billings of customers more than recognized revenues are recorded as a liability in &#x201c;contract liabilities&#x201d;.
However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Technical Support&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Maintenance and technical support services are provided
on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided
outside of a maintenance contract are on an as-requested basis, and revenue is recognized as the services are provided. Revenue for maintenance
and technical support provided on an extended-term basis is recognized ratably over the term of the contract.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales arrangements that do not involve multiple
elements such as professional services, which are of short-term duration, revenues are recognized when services are completed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Consulting Services&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company recognizes revenue from its IT asset management
business in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605-25 which addresses
revenue recognition for the software industry. The general criteria for revenue recognition under ASC 985-605 for our Company, which sells
software licenses, which do not require any significant modification or customization, is that revenue is recognized when persuasive evidence
of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s IT asset management business generates
revenues from three sources: (1) Professional Services (consulting and auditing), (2) Software licensing with optional hardware sales
and (3) Customer Service (training and maintenance support).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales arrangements that do not involve multiple
elements:&#160;&lt;/p&gt;

&lt;td style="width: 2pc"/&gt;&lt;td style="width: 2pc"&gt;(2)&lt;/td&gt;&lt;td style="text-align: justify"&gt;For all periods reflected in this report, software license sales have been one-time sales of a perpetual
license to use our software product and the customer also has the option to purchase third party manufactured handheld devices from us
if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware,
as applicable, to the customer;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 4pc; text-align: justify; text-indent: -2pc"&gt;&#160;&lt;/p&gt;

Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;AI Technologies &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has begun to derive revenue from applications
that incorporate artificial intelligence (AI) in the form of predetermined algorithms to provide important operating information to the
users of our systems. The revenue generated from these applications of AI consists of an annual application maintenance fee which will
be recognized ratably over the year, plus fees for the design, development, testing and incorporation of new algorithms into the system
which will be recognized upon completion of each deliverable.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;









&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Multiple Elements&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements with customers may involve multiple elements
including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project
is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple elements
may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while
other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for
a multiple element arrangement is as follows:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Each element is accounted for separately when each
element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple
element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined
with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of
revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and
software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling
price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based
on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase
maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue
recognition purposes.&lt;/p&gt;

received in excess of revenue recognizable on service agreements that are not accounted for under the percentage of completion method.
At December 31, 2021 and 2020, the balance of deferred revenue was $&lt;span id="xdx_90C_eus-gaap--DeferredRevenue_iI_pp0p0_c20211231_ziA0NXqLVLHi" title="Deferred Revenue"&gt;596,673&lt;/span&gt; and $&lt;span id="xdx_908_eus-gaap--DeferredRevenue_iI_pp0p0_c20201231_zzbeFh4VYqAk" title="Deferred Revenue"&gt;315,370&lt;/span&gt;, respectively. The amounts will be recorded to
revenue over the next 12 months.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company is following the guidance of ASC 606-10-55-296
and 297 for disaggregation of revenue. Accordingly, revenue has been disaggregated according to the nature, amount, timing and uncertainty
of revenue and cash flows. We are providing qualitative and quantitative disclosures.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for employee stock-based compensation
in accordance with ASC 718-10, &#x201c;&lt;i&gt;Share-Based Payment&lt;/i&gt;,&#x201d; which requires the measurement and recognition of compensation
expense for all share-based payment awards made to employees and directors including employee stock options, restricted stock units, and
employee stock purchases based on estimated fair values.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates the fair value of stock options
granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite
service periods of the awards, which is generally the vesting period. The Company&#x2019;s determination of fair value using an option-pricing
model is affected by the stock price as well as assumptions regarding the number of highly subjective variables.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates volatility based upon the historical
stock price of the Company and estimates the expected term for employee stock options using the simplified method for employees and directors
and the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury
securities with similar maturities.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for income taxes in accordance
with the Financial Accounting Standards Board FASB Accounting Standards Codification (&#x201c;ASC&#x201d;) 740, Income Taxes, which requires
the recognition of deferred income taxes for differences between the basis of assets and liabilities for financial statement and income
tax purposes. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either
be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary
to reduce deferred tax assets to the amount expected to be realized.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

all significant tax positions as required by ASC 740. As of December 31, 2021, the Company does not believe that it has taken any positions
that would require the recording of any additional tax liability nor does it believe that there are any unrealized tax benefits that would
either increase or decrease within the next year.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Basic earnings per share (EPS) are computed by dividing
net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is
computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period
and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares
issuable upon the exercise of stock options, stock warrants, convertible debt instruments, convertible preferred stock or other common
stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. At December 31,

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In February 2016, the Financial Accounting Standards
Board (&#x201c;FASB&#x201d;) issued ASU 2016-02, Leases (Topic 842). The updated guidance requires lessees to recognize right-of-use (&#x201c;ROU&#x201d;)
assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and non-lease
components in a contract in accordance with the new revenue guidance in ASC 606. This guidance is effective for interim and annual reporting
periods beginning after December 15, 2018.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company adopted this guidance effective January
1, 2019, using the modified retrospective method, whereby a cumulative effect adjustment was made as of the date of initial application.
The Company also applied the package of practical expedients to leases that commenced before the effective date whereby the Company elected
to not reassess the following: (i) whether any expired or existing contracts contain leases and (ii) initial direct costs for any existing
leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance
sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases
that contain both lease and non-lease components as a single lease component.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The adoption of ASU 2016-02 did not materially affect
our consolidated statement of operations or our consolidated statement of cash flows.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For contracts entered into on or after the effective
date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company&#x2019;s assessment
is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially
all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;From time to time, the FASB or other standards setting
bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards
Update (&#x201c;ASU&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In August 2020,
the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We plan to adopt this pronouncement
for our fiscal year beginning January 1, 2022, and we do not expect it to have a material effect on our consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"/&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In May 2021,
the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2022, and we do not
expect it to have a material effect on our consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Management does not believe that any other recently
issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As reflected in the accompanying consolidated financial
statements, the Company had a net loss of $&lt;span id="xdx_907_eus-gaap--NetIncomeLoss_iN_pp0p0_di_c20210101__20211231_zk1fPOme03j" title="Net income"&gt;6,008,901&lt;/span&gt; for the year ended December 31, 2021. During the same period, cash used in operating
activities was $&lt;span id="xdx_906_eus-gaap--NetCashProvidedByUsedInOperatingActivities_iN_pp0p0_di_c20210101__20211231_znDv9XJ6lpG2" title="Net cash used in operations"&gt;6,579,378&lt;/span&gt;. The negative working capital and accumulated deficit as of December 31, 2021 were $&lt;span id="xdx_907_ecustom--WorkingCapitalDeficit_iNI_pp0p0_di_c20211231_zBTyrPZlsZPe" title="Working capital deficit"&gt;651,381&lt;/span&gt; and $&lt;span id="xdx_907_eus-gaap--RetainedEarningsAccumulatedDeficit_iNI_pp0p0_di_c20211231_zX4jDnMWSKN6" title="Accumulated deficit"&gt;45,497,051&lt;/span&gt;,
respectively. In previous financial reports, the Company had raised substantial doubt about continuing as a going concern. This was principally
due to a lack of working capital prior to an underwritten offering which was completed during the first quarter of 2022 (the &#x201c;2022
Offering&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As previously noted, the Company raised $4,500,000
from existing shareholders through the issuance of Series C Convertible Preferred Stock. Although additional investment is not assured,
the Company is comfortable that it would be able to raise sufficient capital to support expanded operations based on an anticipated increase
in business activity. In the long run, the continuation of the Company as a going concern is dependent upon the ability of the Company
to continue executing the plan described above, generate enough revenue, and attain consistently profitable operations. Although the current
global pandemic related to the coronavirus (Covid-19) has affected our operations, particularly in supply chain, we now believe that this
is expected to be an ongoing issue and our working capital assumptions reflect this new reality. The Company cannot currently quantify
the uncertainty related to the pandemic and its effects on our customers in the coming quarters. We have analyzed our cash flow under
&#x201c;stress test&#x201d; conditions and have determined that we have sufficient liquid assets on hand to maintain operations for at least
twelve months from the date of this report. A notable recent success is the approval of the Company for &#x201c;bonding&#x201d; in the amount
of approximately $8 million for an upcoming major project.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company was successful in securing a loan of $&lt;span id="xdx_909_eus-gaap--SecuredDebt_iI_c20211231_zeBgNGApH6Jh" title="Secured loan"&gt;1,410,270&lt;/span&gt;
during the second quarter of 2020 from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#x2019;s
cash reserves. This loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free. The Company has also
been successful in increasing its working capital surplus after receiving proceeds from the 2021 Offering of $4,500,000 and more recently,
in the first quarter of 2022, receiving net proceeds of approximately $&lt;span id="xdx_90B_eus-gaap--ProceedsFromOtherDebt_c20210101__20211231_zlCk26AbMYm1" title="Net proceeds bebt"&gt;5,500,000&lt;/span&gt; from the successful takedown of the Company&#x2019;s &#x201c;shelf
registration&#x201d; S3. This gives us the capital required to fund the fundamental business changes that we undertook in the last quarter
of 2020, further changes throughout 2021 and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue, and
re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and profitability and
focusing product strategy on opportunities that are likely to bear results in the relatively short term. During 2021, management took
further significant actions including reorganizing our engineering and technical teams and selectively improving organizational efficiency
to effectively grow the business as the expected order flow resumes in 2022. Upon completion of the 2022 Offering, management has raised
sufficient working capital to meet its needs for the next 12-months without the need to raise further capital. Since the advent of the
Covid-19 pandemic, the Company has experienced a significant slowdown in closing new projects due to cautious actions by current and potential
clients. We continue to be successful in identifying new business opportunities and are focused on re-establishing a backlog of projects.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Management believes that, at this time, the conditions
in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including a $5.5M injection of funds from a sale of securities, significant recent orders and the overall stabilization of the business
indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve months from
the issuance of this report. We continue executing the plan to grow our business and achieve profitability without the requirement to
raise additional capital for existing operations for 2022 although we may do so to fund selective opportunities that may arise. Management
has extensively evaluated our requirements for the next 12 months and has determined that the Company currently has sufficient cash to
operate for at least that period.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 26, 2021, the Company entered a new operating

April 30, 2032. This new space will combine the Company&#x2019;s two separate work locations into one facility, which will allow for greater
collaboration and also accommodate a larger anticipated workforce and manufacturing facility. On November 24, 2021, the lease was amended
to commence on December 1, 2021 and end on May 31, 2032. The Company recognized a ROU asset and operating lease liability in the amount
of $&lt;span id="xdx_90F_eus-gaap--OperatingLeaseLiability_iI_c20211124_zwaDo2hGBQgh" title="Operating lease liability"&gt;4,980,104&lt;/span&gt; at lease commencement. Rent for the first eleven months of the term will be calculated based on &lt;span id="xdx_902_ecustom--RentableSpace_usqft_c20210702__20210726_zo95nQvCwTbg" title="Rentable Space"&gt;30,000&lt;/span&gt; rentable square feet.
The rent is subject to an annual escalation of 2.5%, beginning November 1, 2023. The Company made a security deposit payment in the amount
of $&lt;span id="xdx_903_eus-gaap--SecurityDepositLiability_iI_c20210726_zr1AMAWceoi9" title="Security Deposit payment"&gt;600,000&lt;/span&gt; on July 26, 2021.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On November 1, 2021, the Company extended the leases
of office space and warehouse space at its two prior facilities for a period of 30 days to accommodate delays moving to its new headquarters.
The move was completed during 2021.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company had approximately &lt;span id="xdx_90B_ecustom--AreaOfLease_usqft_c20210101__20211231_zV3obzAw68rj"&gt;40,000&lt;/span&gt; square feet of

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As of December 31, 2021, the office and warehouse
lease is the Company&#x2019;s only lease with a term greater than twelve months. The office and warehouse lease has a remaining term of
approximately &lt;span id="xdx_90B_eus-gaap--LesseeOperatingLeaseRemainingLeaseTerm_iI_dtY_c20211231_zognexVyyWj4" title="Remaining lease term"&gt;10.4&lt;/span&gt; years and includes an option to extend for two renewal terms of five years each. The renewal options are not reasonably
certain to be exercised, and therefore, they are not included when determining the lease term used to establish the right-of use asset
and lease liability. The Company also has several short-term leases, primarily related to equipment.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&lt;b&gt;Executive Severance Agreement&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On April 1, 2018, the Company entered into an employment
agreement (the &#x201c;Arcaini Employment Agreement&#x201d;) with Gianni B. Arcaini, pursuant to which Mr. Arcaini served as Chief Executive
Officer and Chairman of the Board of Directors of the Company. Under the Arcaini Employment Agreement, Mr. Arcaini was paid an annual
salary of $&lt;span id="xdx_909_eus-gaap--OfficersCompensation_pp0p0_c20180401__20180430__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zZbjm3bfNyo2" title="Annual salary"&gt;249,260&lt;/span&gt; and an annual car allowance of $&lt;span id="xdx_90A_ecustom--AnnualCarAllowance_c20180401__20180430__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Annual Car allowance"&gt;18,000&lt;/span&gt;. In addition, as incentive-based compensation, Mr. Arcaini was entitled to &lt;span id="xdx_90F_ecustom--PercentageOfGrossRevenue_dp_c20180401__20180430__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_z1ZZ8vpB4Nu" title="Percentage of gross revenue"&gt;1&lt;/span&gt;%
of annual gross revenues of the Company and its subsidiaries. The Arcaini Employment Agreement had an initial term through March 31, 2020,
subject to renewal for successive one-year terms unless either party gave notice of that party&#x2019;s election to not renew to the other
at least 60 days prior to the expiration of the then-current term. The Arcaini Employment Agreement was approved by the Compensation Committee.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As previously disclosed, on July 10, 2020, the Company
announced that Mr. Arcaini would retire from these positions, effective as of September 1, 2020 (the &#x201c;CEO Transition&#x201d;). In
order to facilitate a transition of his duties, the Company and Mr. Arcaini entered into a separation agreement which became effective
as of July 10, 2020 (the &#x201c;Separation Agreement&#x201d;). Pursuant to the Separation Agreement, Mr. Arcaini&#x2019;s employment with
the Company ended on September 1, 2020 and he will receive separation payments over a 36-month period equal to his base salary plus $&lt;span id="xdx_90F_ecustom--AdditionalCompensationToBePaidInSeparationPayments_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Compensation to be paid in addition to base salary in separation payments"&gt;75,000&lt;/span&gt;
as well as certain limited health and life insurance benefits. The Separation Agreement also contains confidentiality, non-disparagement
and non-solicitation covenants and a release of claims by Mr. Arcaini who continued to serve as Chairman of the Board of Directors of
the Company. The Corporate Governance and Nominating Committee did not submit Mr. Arcaini for re-election as a director and on November
19, 2020 at the Annual Shareholders meeting a new non-Executive Chairman was appointed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg75"/&gt;In accordance with the Separation
Agreement, the Company will pay to Mr. Arcaini the total sum of $&lt;span id="xdx_90E_ecustom--OnetimeChargeToBePaidOverThirtySixMonthTermOfSeparationAgreement_iI_pp0p0_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zkrOMK7xdcqj" title="One-time charge which will be amortized in equal amounts over the 36-month term of the separation agreement"&gt;747,788&lt;/span&gt;. Notwithstanding the foregoing, the status of Mr. Arcaini as
a &#x201c;Specified Employee&#x201d; as defined in Internal Revenue Code Section 409A has the effect of delaying any payments to Mr. Arcaini
under the Separation Agreement for six months after the Separation Date. On March 1, 2021, the Company paid to Mr. Arcaini a lump-sum
amount equal to the first six months of payments, or $&lt;span id="xdx_905_ecustom--PaymentOneOfSeparationAgreement_iI_pp0p0_c20210302__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zHr3xRScdUFc" title="Lump sum payment owed under separation agreement"&gt;124,631&lt;/span&gt;, owed to Mr. Arcaini and the Company will continue to pay him in semi-monthly
installments for 30 months thereafter, as contemplated in Mr. Arcaini&#x2019;s Separation Agreement. The remaining balance of approximately
$&lt;span id="xdx_900_eus-gaap--AccruedLiabilitiesCurrent_iI_pp0p0_c20211231__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_zxlLPyhR69kl" title="Accrued Liabilities, Current"&gt;479,000&lt;/span&gt; as of December 31, 2021 is included in accrued expenses in the accompanying consolidated balance sheet. In addition, the Company
will pay one-half of Mr. Arcaini&#x2019;s current life insurance premiums for 36 months of approximately $&lt;span id="xdx_90E_ecustom--PaymentTwoSeparationAgreementForLifeInsurance_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Current life insurance"&gt;1,200&lt;/span&gt; per month and provide and
pay for his health insurance for 36 months following the Separation Date of approximately $450 per month. Unvested options in the amount
of &lt;span id="xdx_903_ecustom--NumberOfUnvestedOptionsThatBecameExercisableAsOfSeparationDate_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pdd" title="Unvested options amount"&gt;50,358&lt;/span&gt; became exercisable and vested in their entirety on the Separation Date valued at $&lt;span id="xdx_90F_ecustom--ValueOfUnvestedOptionsThatBecameExercisableAsOfSeparationDate_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Value of unvested options exercisable"&gt;95,127&lt;/span&gt;. The Company made payment of his attorneys&#x2019;
fees for legal work associated with the negotiation and drafting of the Separation Agreement of approximately $&lt;span id="xdx_90C_eus-gaap--LegalFees_c20200701__20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Legal Fees"&gt;17,000&lt;/span&gt;.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The gross operating loss carryforward was approximately

The Company provided a valuation allowance equal to the deferred
income tax assets for the years ended December 31, 2021 and 2020 because it was not known whether future taxable income will be sufficient
to utilize the loss carryforward and other deferred tax assets. The increase in the valuation allowance was $&lt;span id="xdx_905_eus-gaap--ValuationAllowanceDeferredTaxAssetChangeInAmount_pp0p0_c20210101__20211231_zU0OkfoSSz6e" title="Increase in tax asset valuation allowance"&gt;1,413,637&lt;/span&gt; in 2021.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Aci_Pg76"/&gt;Additionally, the future
utilization of the net operating loss carryforward to offset future taxable income is subject to an annual limitation as a result of ownership
or business changes that may occur in the future. The Company has not conducted a study to determine the limitations on the utilization
of these net operating loss carryforwards. If necessary, the deferred tax assets will be reduced by any carryforward that may not be utilized
or expires prior to utilization as a result of such limitations, with a corresponding reduction of the valuation allowance.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We maintained the 2016 Equity Incentive
Plan (the &#x201c;2016 Plan&#x201d;) for employees, officers, directors and other entities and individuals whose efforts contribute to
our success. The 2016 Plan terminated pursuant to its terms
on December 31, 2020, although all outstanding awards on such date continue in full force and effect.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On May 12, 2021, the Board adopted, with
shareholder approval as of July 15, 2021. The 2021 Equity Incentive Plan (the &#x201c;2021 Plan&#x201d;) providing for the issuance of
up to &lt;span id="xdx_903_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardEquityInstrumentsOtherThanOptionsGrantsInPeriod_c20210101__20211231__us-gaap--PlanNameAxis__custom--TwoThousandsTwentyOneEquityIncentivePlanMember_zqpTN8DZsyYi" title="Issuance of Common stock under Awards"&gt;1,000,000&lt;/span&gt;
shares of our Common Stock. The purpose of the 2021 Plan is to assist the Company in attracting and retaining key employees,
directors and consultants and to provide incentives to such individuals to align their interests with those of our shareholders.&lt;/p&gt;

&lt;p style="font: bold 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: bold 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;General Description of the 2021 Plan&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The following is a summary of the material provisions
of the 2021 Plan and is qualified in its entirety by reference to the complete text of the 2021 Plan, which you are encouraged to read
in full.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Administration&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The 2021 Plan is administered by the Compensation
Committee of the Board, which consists of three members of the Board, each of whom is a &#x201c;non-employee director&#x201d; within the
meaning of Rule 16b-3 promulgated under the Exchange Act and an &#x201c;outside director&#x201d; within the meaning of Code Section 162(m).
Among other things, the Compensation Committee has complete discretion, subject to the express limits of the 2021 Plan, to determine the
directors, employees and nonemployee consultants to be granted an award, the type of award to be granted, the terms and conditions of
the award, the form of payment to be made and/or the number of shares of Common Stock subject to each award, the exercise price of each
option and base price of each stock appreciation right (&#x201c;SAR&#x201d;), the term of each award, the vesting schedule for an award,
whether to accelerate vesting, the value of the Common Stock underlying the award, and the required withholding, if any. The Compensation
Committee may amend, modify or terminate any outstanding award, provided that the participant&#x2019;s consent to such action is required
if the action would impair the participant&#x2019;s rights or entitlements with respect to that award. The Compensation Committee is also
authorized to construe the award agreements and may prescribe rules relating to the 2021 Plan. Notwithstanding the foregoing, the Compensation
Committee does not have any authority to grant or modify an award under the 2021 Plan with terms or conditions that would cause the grant,
vesting or exercise thereof to be considered nonqualified &#x201c;deferred compensation&#x201d; subject to Code Section 409A.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left; text-indent: 1.25pc"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Grant of Awards; Shares Available for Awards&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The 2021 Plan provides for the grant of stock options,
SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock
unit awards and unrestricted stock awards to non-employee directors, officers, employees and nonemployee consultants of the Company or
its affiliates. We have reserved a total of &lt;span id="xdx_90C_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardNumberOfSharesAvailableForGrant_c20211231_pdd" title="Shares available for grant"&gt;1,000,000&lt;/span&gt; shares of Common Stock for issuance as or under awards to be made under the 2021
Plan. If any award expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available
for grant under the 2021 Plan.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left; text-indent: 1.25pc"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Currently, there are 52 identified employees (including
three executive officers, of which one is a director), four non-employee directors, and up to 50 other current or future staff members
who would be eligible to receive stock options and/or shares of restricted stock under the 2021 Plan. Future new hires and additional
non-employee directors and/or consultants would be eligible to participate in the 2021 Plan as well.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Stock Options&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The 2021 Plan provides for either &#x201c;incentive
stock options&#x201d; (&#x201c;ISOs&#x201d;), which are intended to meet the requirements for special federal income tax treatment under
the Code, or &#x201c;nonqualified stock options&#x201d; (&#x201c;NQSOs&#x201d;); provided, however, that ISOs may only be issued if our shareholders
approve the 2021 Plan at the Annual Meeting. Stock options may be granted on such terms and conditions as the Compensation Committee may
determine; provided, however, that the per share exercise price under a stock option may not be less than the fair market value of a share
of the Company&#x2019;s Common Stock on the date of grant and the term of the stock option may &lt;span id="xdx_909_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardTermsOfAward_c20210101__20211231__us-gaap--OptionIndexedToIssuersEquityTypeAxis__us-gaap--EmployeeStockOptionMember" title="Common stock on the date of grant, term of the stock option"&gt;not exceed 10 years&lt;/span&gt; (110% of such value
and five years in the case of an ISO granted to an employee who owns (or is deemed to own) &lt;span id="xdx_90C_eus-gaap--CommonStockVotingRights_c20210101__20211231__us-gaap--OptionIndexedToIssuersEquityTypeAxis__us-gaap--EmployeeStockOptionMember" title="Voting rights"&gt;more than 10% of the total combined voting
power of all classes of capital stock&lt;/span&gt; of the Company or a parent or subsidiary of the Company). ISOs may only be granted to employees.
In addition, the aggregate fair market value of our Common Stock covered by one or more ISOs (determined at the time of grant) which are
exercisable for the first time by an employee during any calendar year may not exceed $&lt;span id="xdx_909_ecustom--AggregateFairMarketValueOfOurCommonStockNotExceed_c20210101__20211231__us-gaap--OptionIndexedToIssuersEquityTypeAxis__us-gaap--EmployeeStockOptionMember_pp0p0" title="Aggregate fair market value of common stock"&gt;100,000&lt;/span&gt;. Any excess is treated as a NQSO.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Stock Appreciation Rights&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;An SAR entitles the participant, upon exercise, to
receive an amount, in cash or stock or a combination thereof, equal to the increase in the fair market value of the underlying Common
Stock between the date of grant and the date of exercise. SARs may be granted in tandem with, or independently of, stock options granted
under the 2021 Plan. An SAR granted in tandem with a stock option (i) is exercisable only at such times, and to the extent, that the related
stock option is exercisable in accordance with the procedure for exercise of the related stock option; (ii) terminates upon termination
or exercise of the related stock option (likewise, the Common Stock option granted in tandem with a SAR terminates upon exercise of the
SAR); (iii) is transferable only with the related stock option; and (iv) if the related stock option is an ISO, may be exercised only
when the value of the stock subject to the stock option exceeds the exercise price of the stock option. An SAR that is not granted in
tandem with a stock option is exercisable at such times as the Compensation Committee may specify.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left; text-indent: 1.25pc"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Performance Share and Performance Unit Awards&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Performance share and performance unit awards entitle
the participant to receive cash or shares of our Common Stock upon the attainment of specified performance goals. In the case of performance
units, the right to acquire the units is denominated in cash values.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left; text-indent: 1.25pc"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Restricted Stock Awards and Restricted Stock
Unit Awards&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A restricted stock award is a grant or sale of Common
Stock to the participant, subject to our right to repurchase all or part of the shares at their purchase price (or to require forfeiture
of such shares if issued to the participant at no cost) in the event that conditions specified by the Compensation Committee in the award
are not satisfied prior to the end of the time period during which the shares subject to the award may be repurchased by or forfeited
to us. Our restricted stock unit entitles the participant to receive a cash payment equal to the fair market value of a share of Common
Stock for each restricted stock unit subject to such restricted stock unit award, if the participant satisfies the applicable vesting
requirement.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left; text-indent: 1.25pc"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Unrestricted Stock Awards&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;An unrestricted stock award is a grant or sale of
shares of our Common Stock to the participant that is not subject to transfer, forfeiture or other restrictions, in consideration for
past services rendered to the Company or an affiliate or for other valid consideration.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left; text-indent: 1.25pc"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Amendment and Termination&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Compensation Committee may adopt, amend and rescind
rules relating to the administration of the 2021 Plan, and amend, suspend or terminate the 2021 Plan, but no such amendment, rescission,
suspension or termination will be made that materially and adversely impairs the rights of any participant with respect to any award received
thereby under the 2021 Plan without the participant&#x2019;s consent, other than amendments that are necessary to permit the granting of
awards in compliance with applicable laws.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Certain Federal Income Tax Consequences of the
2021 Plan &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The following is a general summary of the federal
income tax consequences under current U.S. tax law to the Company and to participants in the 2021 Plan who are individual citizens or
residents of the United States for federal income tax purposes (&#x201c;U.S. Participants&#x201d;) of stock options, stock appreciation
rights, restricted stock, performance shares, performance units, restricted stock units, distribution equivalent rights and unrestricted
stock. It does not purport to cover all of the special rules including special rules relating to limitations on the ability of the Company
to deduct the amounts for federal income tax purposes of certain compensation, special rules relating to deferred compensation, golden
parachutes, participants subject to Section 16(b) of the Exchange Act or the exercise of a stock option with previously acquired shares
of the Company&#x2019;s Common Stock. For purposes of this summary, it is assumed that U.S. Participants will hold their shares of the
Company&#x2019;s Common Stock received under the 2021 Plan as capital assets within the meaning of Section 1221 of the Code. In addition,
this summary does not address the non-U.S. state or local income or other tax consequences, or any U.S. federal non-income tax consequences,
inherent in the acquisition, ownership, vesting, exercise, termination or disposition of an award under the 2021 Plan or shares of the
Company&#x2019;s Common Stock issued pursuant thereto. All participants are urged to consult with their own tax advisors concerning the
tax consequences to them of an award under the 2021 Plan or shares of the Company&#x2019;s Common Stock issued thereto pursuant to the
2021 Plan.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A U.S. Participant does not recognize taxable income
upon the grant of a NQSO or an ISO. Upon the exercise of a NQSO, the U.S. Participant recognizes ordinary income in an amount equal to
the excess, if any, of the fair market value of the shares acquired on the date of exercise over the exercise price paid therefor under
the NQSO, and the Company will generally be entitled to a deduction for such amount at that time. If the U.S. Participant later sells
shares acquired pursuant to the exercise of a NQSO, the U.S. Participant recognizes long-term or short-term capital gain or loss, depending
on the period for which the shares were held. Long-term capital gain is generally subject to more favorable tax treatment than ordinary
income or short-term capital gain. Upon the exercise of an ISO, the U.S. Participant does not recognize taxable income. If the U.S. Participant
disposes of the shares acquired pursuant to the exercise of an ISO more than two years after the date of grant and more than one year
after the transfer of the shares to the U.S. Participant, the U.S. Participant recognizes long-term capital gain or loss, and the Company
will not be entitled to a deduction. However, if the U.S. Participant disposes of such shares prior to the end of the required holding
period, all or a portion of the gain is treated as ordinary income and the Company is generally entitled to deduct such amount. In addition
to the tax consequences described above, a U.S. Participant may be subject to the alternative minimum tax, which is payable to the extent
it exceeds the U.S. Participant&#x2019;s regular tax. For this purpose, upon the exercise of an ISO, the excess of the fair market value
of the shares over the exercise price paid therefor under the ISO is a preference item for alternative minimum taxable income determination
purposes. In addition, the U.S. Participant&#x2019;s basis in such shares is increased by such excess for purposes of computing the gain
or loss on the disposition of the shares for alternative minimum tax purposes.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A U.S. Participant does not recognize taxable income
upon the grant of an SAR. The U.S. Participant has ordinary compensation income upon exercise of the SAR equal to the increase in the
value of the underlying shares, and the Company will generally be entitled to a deduction for such amount.&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A U.S. Participant does not recognize taxable income
upon the receipt of a performance share award until the shares are received. At such time, the U.S. Participant recognizes ordinary compensation
income equal to the excess, if any, of the fair market value of the shares over any amount thereby paid for the shares, and the Company
will generally be entitled to deduct such amount at such time.&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A U.S. Participant does not recognize taxable income
upon the receipt of a performance unit award, restricted stock unit award or dividend equivalent right award until a cash payment is received.
At such time, the U.S. Participant recognizes ordinary compensation income equal to the amount of cash received, and the Company will
generally be entitled to deduct such amount at such time.&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A U.S. Participant who receives a grant of restricted
stock generally recognizes ordinary compensation income equal to the excess, if any, of the fair market value of such shares of stock
at the time the restriction lapses over any amount paid timely for the shares. Alternatively, the U.S. Participant may elect to be taxed
on the fair market value of such shares at the time of grant. The Company thereby will generally be entitled to a deduction at the same
time and in the same amount as the income required to be included by the U.S. Participant.&lt;/p&gt;

&lt;p style="font: 10pt/8pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A U.S. Participant recognizes ordinary compensation
income upon receipt of the shares under an unrestricted stock award equal to the excess, if any, of the fair market value of the shares
over any amount paid thereby for the shares, and the Company will generally be entitled to deduct such amount at such time.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On February 26, 2021, the Company entered into
a Securities Purchase Agreement (the &#x201c;Purchase Agreement&#x201d;) with certain existing investors in the Company (the &#x201c;Purchasers&#x201d;).
Pursuant to the Purchase Agreement, the Purchasers purchased 4,500 shares of a newly authorized Series C Convertible Preferred Stock (the

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under the Purchase Agreement, the Company was
required to hold a meeting of shareholders at the earliest practical date, and such meeting occurred on July 15, 2021. Nasdaq Marketplace
Rule 5635(d) limits the number of shares of common stock (or securities that are convertible into common stock) without shareholder approval
and the terms of the Series C Convertible Preferred Stock limit its convertibility to a number of shares less than the 20% limit, until
the Stockholder Approval is obtained. The Company obtained shareholder approval (the &#x201c;Stockholder Approval&#x201d;) in order to issue
shares of common stock underlying the Series C Convertible Preferred Stock at a price less than the greater of book or market value which
equal 20% or more of the number of shares of common stock outstanding before the issuance. As described below, the terms of the Series C Convertible Preferred Stock
limited its convertibility to a number of shares less than the 20% limit, until the Stockholder Approval was obtained.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In connection with the Purchase Agreement, the Company
also entered into a Registration Rights Agreement with the Purchasers. Pursuant to the Registration Rights Agreement, the Company filed
with the SEC a registration statement covering the resale by the Purchasers of the shares of common stock into which the shares of Series
C Convertible Preferred Stock are convertible. The Company caused the registration statement to be declared effective on June 3, 2021.
The Registration Rights Agreement contains customary representations, warranties, agreements and indemnification rights and obligations
of the parties.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0pc"&gt;The Company&#x2019;s Board of Directors
has designated 5,000 shares as the Series C Convertible Preferred Stock. Each share of the Series C Convertible Preferred Stock has a
stated value of $1,000. The holders of the Series C Convertible Preferred Stock, the holders of the common stock and the holders of any
other class or series of shares entitled to vote with the common stock shall vote together as one class on all matters submitted to a
vote of shareholders of the Company. Each share of Series C Convertible Preferred Stock has 172 votes (subject to adjustment); provided
that in no event may a holder of Series C Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder&#x2019;s
Beneficial Ownership Limitation (as defined in the Certificate of Designation and as described below). Each share of Series C Convertible
Preferred Stock is convertible, at any time and from time to time, at the option of the holder, into that number of shares of common
stock (subject to the Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion
price, which is $5.50 (subject to adjustment). The Company shall not effect any conversion of the Series C Convertible Preferred Stock,
and a holder shall not have the right to convert any portion of the Series C Convertible Preferred Stock, to the extent that after giving
effect to the conversion sought by the holder such holder (together with such holder&#x2019;s Attribution Parties (as defined in the Certificate
of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock
outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion (the &#x201c;Beneficial
Ownership Limitation&#x201d;). All holders of the Series C Preferred Stock have elected the 19.99% Beneficial Ownership Limitation.&lt;/p&gt;

contractors located in Slovakia at a cost of $&lt;span id="xdx_900_eus-gaap--RelatedPartyCosts_c20190101__20190131_z8qwvRUtaeik"&gt;16,250&lt;/span&gt; for January initially, rising to $&lt;span id="xdx_904_eus-gaap--RelatedPartyCosts_c20190201__20190228_zRKeyyZr2Gra"&gt;25,583&lt;/span&gt; after fully staffed, per month starting
February 2019. This was in addition to the existing contract of $&lt;span id="xdx_902_eus-gaap--RelatedPartyCosts_c20190601__20190630__srt--ProductOrServiceAxis__custom--ContractorsMember_zcn50ms3Mkkj"&gt;7,480&lt;/span&gt; per month for duos for 4 full-time contractors which increased
to $&lt;span id="xdx_901_eus-gaap--RelatedPartyCosts_c20190601__20190630_zohq2TurrMa1"&gt;8,231&lt;/span&gt; per month in June of 2019. During 2020 efforts in reducing cost, Luceon reduced its staff for the TrueVue360 software development
team from a staff of 7 to 3 full-time employees at a cost of $11,666 per month starting June 1, 2020. As of January 1, 2021, the Company
no longer records activities in TrueVue360 and has combined billings for a total of $&lt;span id="xdx_905_eus-gaap--AccountsPayableRelatedPartiesCurrentAndNoncurrent_iI_c20210102_z8qyaelKzoz6" title="Accounts payable"&gt;20,986&lt;/span&gt; per month. For the nine months ended December
31, 2021 and 2020, the total amount expensed is $&lt;span id="xdx_909_eus-gaap--RelatedPartyCosts_c20210101__20211231_z565Cpll9mQl" title="Related party cost"&gt;93,422&lt;/span&gt; and $&lt;span id="xdx_906_eus-gaap--RelatedPartyCosts_c20200101__20201231_z00kTsJicTUi"&gt;335,334&lt;/span&gt;, respectively. The Company had no open accounts payable with Luceon
at December 31, 2021. On May 14, 2021, the Company formally ended its relationship with Luceon in concert with the resignation of our
Chief Technology Officer and as such there is no longer a related party relationship.&lt;/p&gt;
