is a pioneer and global leader in surgical robotics for minimally invasive endovascular intervention. We design, manufacture and market
robotic systems, instruments and information systems for the interventional laboratory. Our proprietary robotic technology, Robotic Magnetic
Navigation, fundamentally transforms endovascular interventions using precise computer-controlled magnetic fields to directly control
the tip of flexible interventional catheters or devices. Direct control of the tip of an interventional device, in contrast to all manual
hand-held devices that are controlled from their handle, can improve the precision, stability, reach and safety of these devices during
procedures.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.3in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

primary clinical focus has been electrophysiology, specifically cardiac ablation procedures for the treatment of arrhythmias. Cardiac
ablation has become a well-accepted therapy for arrhythmias and a multi-billion-dollar medical device market with expectations for substantial
long-term growth. We have shared our aspiration and a product strategy to expand the clinical focus of our technology to several additional
endovascular indications including coronary, neuro, and peripheral interventions.&lt;/span&gt;&lt;/p&gt;

is substantial real-world evidence and clinical literature for Robotic Magnetic Navigation in electrophysiology. Hundreds of electrophysiologists
at over one hundred hospitals globally have treated over 100,000 arrhythmia patients with our robotic technology. Clinical use of our
technology has been documented in over 400 clinical publications. Robotic Magnetic Navigation is designed to enable physicians to complete
more complex interventional procedures with greater success and safety by providing image-guided delivery of catheters through the blood
vessels and chambers of the heart to treatment sites. This is achieved using externally applied computer-controlled magnetic fields that
govern the motion of the working tip of the catheter, resulting in improved navigation. The more flexible atraumatic design of catheters
driven using magnetic fields may reduce the risk of patient harm and other adverse events. Performing the procedure from a control cockpit
enables physicians to complete procedures in a safe location protected from x-ray exposure, with greater ergonomics, and improved efficiency.
We believe these benefits can be applicable in other endovascular indications where navigation through complex vasculature is often challenging
or unsuccessful and generates significant x-ray exposure.&lt;/span&gt;&lt;/p&gt;

novel coronavirus COVID-19 (&#x201c;COVID-19&#x201d;) pandemic has resulted, and is likely to continue to result, in significant disruptions
to the economy, as well as business and capital markets around the world. The full extent of the impact of the COVID-19 pandemic on our
business, results of operations and financial condition will depend on numerous evolving factors that we may not be able to accurately
predict.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.35in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

a result of the COVID-19 outbreak, we have experienced business disruptions, including travel restrictions on us and our third-party
distributors, which have negatively affected our complex sales, marketing, installation, distribution and service network relating to
our products and services. The COVID-19 pandemic may continue to negatively affect demand for both our systems and our disposable products
by limiting the ability of our sales personnel to maintain their customary contacts with customers as governmental authorities institute
prolonged quarantines, travel restrictions, and shelter-in-place orders, or as our customers impose limitations on contacts and in-person
meetings that go beyond those imposed by governmental authorities.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.3in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

addition, many of our hospital customers, for whom the purchase of our system involves a significant capital purchase which may be part
of a larger construction project at the customer site (typically the construction of a new building), may themselves be under economic
pressures. This may cause delays or cancellations of current purchase orders and other commitments, and may exacerbate the long and variable
sales and installation cycles for our robotic magnetic navigation systems. We may also experience significant reductions in demand for
our disposable products as our healthcare customers (physicians and hospitals) continue to re-prioritize the treatment of patients and
divert resources away from non-coronavirus areas, which we anticipate will lead to the performance of fewer procedures in which our disposable
products are used. In addition, patients may consider foregoing or deferring procedures utilizing our products, even if physicians and
hospitals are willing to perform them, which could also reduce demand for, and sales of, our disposable products.&lt;/span&gt;&lt;/p&gt;

of the date of the filing of this Quarterly Report on Form 10-Q, we believe our manufacturing operations and supply chains have been
manageably impacted, but we cannot guarantee that they will not be impacted more severely in the future. If our manufacturing operations
or supply chains are materially interrupted, it may not be possible for us to timely manufacture relevant products at required levels,
or at all. Changes in economic conditions and supply chain constraints could lead to higher inflation than previously experienced or
expected, which could, in turn, lead to an increase in costs. We may be unable to raise the prices of our products sufficiently to keep
up with the rate of inflation. A material reduction or interruption to any of our manufacturing processes or a substantial increase in
costs would have a material adverse effect on our business, operating results, and financial condition.&lt;/span&gt;&lt;/p&gt;

governmental authorities around the world continue to institute prolonged mandatory closures, social distancing protocols and shelter-in-place
orders, or as private parties on whom we rely to operate our business put in place their own protocols that go beyond those instituted
by relevant governmental authorities, our ability to adequately staff and maintain our operations or further our product development
could be negatively impacted.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.3in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

disruption to the capital markets could negatively impact our ability to raise capital. If the capital markets are disrupted for an extended
period of time and we need to raise additional capital, such capital may not be available on acceptable terms, or at all. Continued disruptions
to the capital markets and other financing sources could also negatively impact our hospital customers&#x2019; ability to raise capital
or otherwise obtain financing to fund their operations and capital projects. Such could result in delayed spending on current projects,
a longer sales cycle for new projects where a large capital commitment is required, and decreased demand for our disposable products
as well as an increased risk of customer defaults or delays in payments for our systems installation, service contracts and disposable
products.&lt;/span&gt;&lt;/p&gt;

contracts containing multiple products and services, the Company accounts for individual products and services as separate performance
obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package,
and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes
revenues as the performance obligations are satisfied by transferring control of the product or service to a customer.&lt;/span&gt;&lt;/p&gt;

arrangements with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone
selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services.
If a standalone selling price is not directly observable, then the Company estimates the standalone selling price considering market
conditions and entity-specific factors including, but not limited to, features and functionality of the products and services and market
conditions. The Company regularly reviews standalone selling prices and updates these estimates if necessary.&lt;/span&gt;&lt;/p&gt;

Company invoices its customers based on the billing schedules in its sales arrangements. Contract assets primarily represent the difference
between the revenue that was earned but not billed on service contracts and revenue from system contracts that was recognized based on
the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Customer deposits
primarily relate to future system sales but can also include deposits on disposable sales. Deferred revenue is primarily related to service
contracts, for which the service fees are billed up-front, generally quarterly or annually, and for amounts billed in advance for system
contracts for which some performance obligations remain outstanding. For service contracts, the associated deferred revenue is generally
recognized ratably over the service period. For system contracts, the associated deferred revenue is recognized when the remaining performance
obligations are satisfied. The Company did not have any impairment losses on its contract assets for the periods presented.&lt;/span&gt;&lt;/p&gt;

Company accounts for its grants of stock options, stock appreciation rights, restricted shares, restricted stock units and for its employee
stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles
require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense
over the period in which the share-based compensation vests.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

time-based awards, the Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation
rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four
years. Restricted shares and units granted to employees are valued at the fair market value at the date of grant. The Company amortizes
the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation
expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.&lt;/span&gt;&lt;/p&gt;

market-based awards, stock-based compensation expense is recognized over the minimum service period regardless of whether or not the
market target is probable of being achieved. The fair value of such awards is estimated on the grant date using Monte Carlo simulations.&lt;/span&gt;&lt;/p&gt;

earnings (loss) per common share is computed by dividing the net earnings (loss) for the period by the weighted average number of common
shares outstanding during the period. In periods where there is net income, we apply the two-class method to calculate basic and diluted
net income (loss) per share of common stock, as our convertible preferred stock is a participating security. The two-class method is
an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available
to common stockholders. In periods where there is a net loss, the two-class method of computing earnings per share does not apply as
our convertible preferred stock does not contractually participate in our losses. We compute diluted net income (loss) per common share
using net income (loss) as the &#x201c;control number&#x201d; in determining whether potential common shares are dilutive, after giving
consideration to all potentially dilutive common shares, including stock options, warrants, unvested restricted stock units outstanding
during the period and potential issuance of stock upon the conversion of our convertible preferred stock issued and outstanding during
the period, except where the effect of such securities would be antidilutive.&lt;/span&gt;&lt;/p&gt;

Instruments&#x201d; and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The
standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred
loss method to a current expected credit loss method, otherwise known as &#x201c;CECL.&#x201d; The standard requires the measurement of
expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is
supportable. The standard is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal
years; early adoption is permitted. The standard must be adopted by applying a cumulative adjustment to retained earnings. The Company
anticipates adopting the standard in the first quarter of 2023, although it does not expect a significant impact to the Company&#x2019;s
financial results.&lt;/span&gt;&lt;/p&gt;

novel coronavirus COVID-19 (&#x201c;COVID-19&#x201d;) pandemic has resulted, and is likely to continue to result, in significant disruptions
to the economy, as well as business and capital markets around the world. The full extent of the impact of the COVID-19 pandemic on our
business, results of operations and financial condition will depend on numerous evolving factors that we may not be able to accurately
predict.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.35in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

a result of the COVID-19 outbreak, we have experienced business disruptions, including travel restrictions on us and our third-party
distributors, which have negatively affected our complex sales, marketing, installation, distribution and service network relating to
our products and services. The COVID-19 pandemic may continue to negatively affect demand for both our systems and our disposable products
by limiting the ability of our sales personnel to maintain their customary contacts with customers as governmental authorities institute
prolonged quarantines, travel restrictions, and shelter-in-place orders, or as our customers impose limitations on contacts and in-person
meetings that go beyond those imposed by governmental authorities.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.3in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

addition, many of our hospital customers, for whom the purchase of our system involves a significant capital purchase which may be part
of a larger construction project at the customer site (typically the construction of a new building), may themselves be under economic
pressures. This may cause delays or cancellations of current purchase orders and other commitments, and may exacerbate the long and variable
sales and installation cycles for our robotic magnetic navigation systems. We may also experience significant reductions in demand for
our disposable products as our healthcare customers (physicians and hospitals) continue to re-prioritize the treatment of patients and
divert resources away from non-coronavirus areas, which we anticipate will lead to the performance of fewer procedures in which our disposable
products are used. In addition, patients may consider foregoing or deferring procedures utilizing our products, even if physicians and
hospitals are willing to perform them, which could also reduce demand for, and sales of, our disposable products.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.3in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

of the date of the filing of this Quarterly Report on Form 10-Q, we believe our manufacturing operations and supply chains have been
manageably impacted, but we cannot guarantee that they will not be impacted more severely in the future. If our manufacturing operations
or supply chains are materially interrupted, it may not be possible for us to timely manufacture relevant products at required levels,
or at all. Changes in economic conditions and supply chain constraints could lead to higher inflation than previously experienced or
expected, which could, in turn, lead to an increase in costs. We may be unable to raise the prices of our products sufficiently to keep
up with the rate of inflation. A material reduction or interruption to any of our manufacturing processes or a substantial increase in
costs would have a material adverse effect on our business, operating results, and financial condition.&lt;/span&gt;&lt;/p&gt;

governmental authorities around the world continue to institute prolonged mandatory closures, social distancing protocols and shelter-in-place
orders, or as private parties on whom we rely to operate our business put in place their own protocols that go beyond those instituted
by relevant governmental authorities, our ability to adequately staff and maintain our operations or further our product development
could be negatively impacted.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.3in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

disruption to the capital markets could negatively impact our ability to raise capital. If the capital markets are disrupted for an extended
period of time and we need to raise additional capital, such capital may not be available on acceptable terms, or at all. Continued disruptions
to the capital markets and other financing sources could also negatively impact our hospital customers&#x2019; ability to raise capital
or otherwise obtain financing to fund their operations and capital projects. Such could result in delayed spending on current projects,
a longer sales cycle for new projects where a large capital commitment is required, and decreased demand for our disposable products
as well as an increased risk of customer defaults or delays in payments for our systems installation, service contracts and disposable
products.&lt;/span&gt;&lt;/p&gt;

continue to evaluate and, where appropriate, take actions to reduce costs and spending across our organization. We will continue to actively
monitor the situation and may take further actions that alter our business operations that may be required by federal, state, or local
governmental authorities that may be implemented by our vendors, supplier or customers, or that we determine are in the best interests
of our employees, customers, suppliers and stockholders.&lt;/span&gt;&lt;/p&gt;

Company measures certain financial assets and liabilities at fair value on a recurring basis. General accounting principles for fair
value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value.

contracts containing multiple products and services, the Company accounts for individual products and services as separate performance
obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package,
and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes
revenues as the performance obligations are satisfied by transferring control of the product or service to a customer.&lt;/span&gt;&lt;/p&gt;

arrangements with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone
selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services.
If a standalone selling price is not directly observable, then the Company estimates the standalone selling price considering market
conditions and entity-specific factors including, but not limited to, features and functionality of the products and services and market
conditions. The Company regularly reviews standalone selling prices and updates these estimates if necessary.&lt;/span&gt;&lt;/p&gt;

related to the sale of systems typically contain separate obligations for the delivery of system(s), installation and an implied obligation
to provide software enhancements if and when available for one year following installation. Revenue is recognized when the Company transfers
control to the customer, which is generally at the point when acceptance occurs that indicates customer acknowledgment of delivery or
installation, depending on the terms of the arrangement. Revenue from the implied obligation to deliver software enhancements if and
when available is recognized ratably over the first year following installation of the system as the customer receives the right to software

Company invoices its customers based on the billing schedules in its sales arrangements. Contract assets primarily represent the difference
between the revenue that was earned but not billed on service contracts and revenue from system contracts that was recognized based on
the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Customer deposits
primarily relate to future system sales but can also include deposits on disposable sales. Deferred revenue is primarily related to service
contracts, for which the service fees are billed up-front, generally quarterly or annually, and for amounts billed in advance for system
contracts for which some performance obligations remain outstanding. For service contracts, the associated deferred revenue is generally
recognized ratably over the service period. For system contracts, the associated deferred revenue is recognized when the remaining performance
obligations are satisfied. The Company did not have any impairment losses on its contract assets for the periods presented.&lt;/span&gt;&lt;/p&gt;

Company accounts for its grants of stock options, stock appreciation rights, restricted shares, restricted stock units and for its employee
stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles
require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense
over the period in which the share-based compensation vests.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

time-based awards, the Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation
rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four
years. Restricted shares and units granted to employees are valued at the fair market value at the date of grant. The Company amortizes
the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation
expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 32.05pt"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

market-based awards, stock-based compensation expense is recognized over the minimum service period regardless of whether or not the
market target is probable of being achieved. The fair value of such awards is estimated on the grant date using Monte Carlo simulations.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.35in"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

earnings (loss) per common share is computed by dividing the net earnings (loss) for the period by the weighted average number of common
shares outstanding during the period. In periods where there is net income, we apply the two-class method to calculate basic and diluted
net income (loss) per share of common stock, as our convertible preferred stock is a participating security. The two-class method is
an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available
to common stockholders. In periods where there is a net loss, the two-class method of computing earnings per share does not apply as
our convertible preferred stock does not contractually participate in our losses. We compute diluted net income (loss) per common share
using net income (loss) as the &#x201c;control number&#x201d; in determining whether potential common shares are dilutive, after giving
consideration to all potentially dilutive common shares, including stock options, warrants, unvested restricted stock units outstanding
during the period and potential issuance of stock upon the conversion of our convertible preferred stock issued and outstanding during
the period, except where the effect of such securities would be antidilutive.&lt;/span&gt;&lt;/p&gt;

June 2016, the FASB issued ASU 2016-13, &#x201c;Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial
Instruments&#x201d; and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The
standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred
loss method to a current expected credit loss method, otherwise known as &#x201c;CECL.&#x201d; The standard requires the measurement of
expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is
supportable. The standard is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal
years; early adoption is permitted. The standard must be adopted by applying a cumulative adjustment to retained earnings. The Company
anticipates adopting the standard in the first quarter of 2023, although it does not expect a significant impact to the Company&#x2019;s
financial results.&lt;/span&gt;&lt;/p&gt;

lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment
for a period of time in exchange for consideration. The Company accounts for leases in accordance with Accounting Standards Update No.

Company leases its facilities under operating leases. In accordance with ASC 842, operating lease agreements are recognized on the balance
sheet as a right-of-use (&#x201c;ROU&#x201d;) asset and a corresponding lease liability. These leases generally do not have significant
rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain
contingent rent provisions. Many of our leases include both lease and non-lease components which are accounted for as a single lease
component as we have elected the practical expedient to group lease and non-lease components for all leases. A portion of our former
principal executive office was subleased to a third party through 2021. The sublease did not have significant rent escalation holidays,
concessions, leasehold improvement incentives, or other build-out clauses. In addition, the sublease did not contain contingent rent
provisions nor were there options to extend or terminate the sublease. The sublease ended December 31, 2021.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s lease agreements often include one or more options to renew at the Company&#x2019;s discretion. If at lease inception,
the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the
calculation of the ROU asset and lease liability. The Company elected not to include short-term leases (i.e. leases with initial terms
of twelve months or less) on the balance sheet.&lt;/span&gt;&lt;/p&gt;

the ROU asset and lease liability was $&lt;span id="xdx_908_eus-gaap--OperatingLeaseLiabilityNoncurrent_iI_pn5n6_c20210930_zkW7CiyRazKc" title="Operating lease liability"&gt;&lt;span id="xdx_900_eus-gaap--OperatingLeaseRightOfUseAsset_iI_pn5n6_c20210930_zxqjcqMvmvsd" title="Operating lease, right-of-use asset"&gt;5.9&lt;/span&gt;&lt;/span&gt; million. In the fourth quarter of 2021, the Company received an occupancy permit and relocated
its operations to the new leased space.&lt;/span&gt;&lt;/p&gt;

calculated amounts of the ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to
calculate the present value of the minimum lease payments. ASC 842 requires the use of the discount rate implicit in the lease whenever
this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease
inception. As of March 31, 2022, the weighted average discount rate for operating leases was &lt;span id="xdx_90F_eus-gaap--OperatingLeaseWeightedAverageDiscountRatePercent_iI_pid_dp_c20220331_zP8gegAvCkU2" title="Weighted average discount rate, operating lease"&gt;9&lt;/span&gt;% and the weighted average remaining lease
term for operating lease term is &lt;span id="xdx_905_eus-gaap--OperatingLeaseWeightedAverageRemainingLeaseTerm1_iI_dtY_c20220331_zmtRfrID9Cpl" title="Weighted average remaining lease term, operating lease"&gt;9.75&lt;/span&gt; years.&lt;/span&gt;&lt;/p&gt;

Coronavirus Aid, Relief, and Economic Security Act (&#x201c;CARES Act&#x201d;) was enacted on March 27, 2020 in the United States. Among
the provisions contained in the CARES Act was the creation of the Paycheck Protection Program that provides for Small Business Administration
(&#x201c;SBA&#x201d;) Section 7(a) loans for qualified small businesses. In general, the loan could be forgiven as long as the funds were
used for payroll related expenses as well as rent and utilities paid during the twenty-four-week period from the date of the loan and
as long as certain headcount and salary/wage levels were maintained. On April 10, 2020, the Company was informed by its lender, Midwest
BankCentre (the &#x201c;Bank&#x201d;), that the Bank received approval from the SBA to fund the Company&#x2019;s request for a loan under
the SBA&#x2019;s Paycheck Protection Program (&#x201c;PPP Loan&#x201d;). Per the terms of the PPP Loan, the Company received total proceeds
of approximately $&lt;span id="xdx_901_eus-gaap--ProceedsFromBankDebt_pn5n6_c20200419__20200420__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramMember_z4hA6aDS9ur1" title="Proceed from bank loan"&gt;2.2&lt;/span&gt; million from the Bank on April 20, 2020. In accordance with the loan forgiveness requirements of the CARES Act,
the Company used the full proceeds from the PPP Loan primarily for payroll costs, rent and utilities. In March 2021, the Company applied
for loan forgiveness and in June 2021 full loan forgiveness was granted by the SBA. The Company recognized a net gain from debt extinguishment
of approximately $&lt;span id="xdx_903_eus-gaap--GainsLossesOnExtinguishmentOfDebt_pn5n6_c20210601__20210630__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramMember_zeiUyaUpk4Ib" title="Gain on extinguishment of debt"&gt;2.2&lt;/span&gt; million.&lt;/span&gt;&lt;/p&gt;

of the market capitalization milestones and (ii) continued employment as CEO of the Company from the grant date through December 31,

any reason including death, disability, termination for cause or without cause (as defined in the award agreement), or if he voluntary
terminates after service as CEO for at least five years, the remaining service period will be waived and he will retain any PSUs that

Company measures certain financial assets and liabilities at fair value on a recurring basis, including certain cash equivalents. Generally
accepted accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation
techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical
assets and liabilities (&#x201c;Level 1&#x201d;) and the lowest priority to unobservable inputs (&#x201c;Level 3&#x201d;). The three levels
of the fair value hierarchy are described below:&lt;/span&gt;&lt;/p&gt;
