accounting principles in the United States of America (“GAAP”) for interim financial information and with the instructions
to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.
In the opinion of management, such financial statements include all adjustments (consisting solely of normal recurring adjustments) necessary
for the fair statement of the financial information included herein in accordance with GAAP and the rules and regulations of the Securities
and Exchange Commission (the “SEC”). The balance sheet at December 31, 2020 has been derived from the audited consolidated
financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements
and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates. Results of operations
for interim periods are not necessarily indicative of results for the full year. The accompanying condensed consolidated financial statements
should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form
10-K for the year ended December 31, 2020 as filed with the SEC on April 8, 2021.</font></p>

during the period under the treasury stock method. Such potential dilutive common shares consist of stock options, warrants to purchase
our Common Stock (the “Warrants”) and convertible debt. Potential common shares totaling approximately 211,000,000 and 174,000,000

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">On April 10, 2020, the Company received loan proceeds in the amount of $781,800 pursuant to a promissory note agreement (the “Promissory Note”) with a bank under the Paycheck Protection Program (“PPP”). The PPP, established as part of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), provides for loans to qualifying businesses for amounts up to 2.5 times of the average monthly payroll expenses of the qualifying business. The Promissory Note has a loan maturity of April 10, 2022, a stated interest rate of 1.0% per annum, and has payments of principal and interest that are due monthly after an initial six-month deferral period where interest accrues, but no payments are due. The Promissory Note provides for customary events of default, including, among others, those relating to failure to make payment when due and breaches of representations. The Company may prepay the principal of the Promissory Note at any time without incurring any prepayment charges. The loan is subject to all the terms and conditions applicable under the PPP and is subject to review by the Small Business Association (the “SBA”) for compliance with program requirements, including the Company’s certification that the current economic uncertainty made the PPP loan request necessary to support ongoing operations and the Company’s obtaining approval from the SBA for the private placement equity transaction.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">In June 2020, the Payroll Protection Program Flexibility Act (“PPPFA”) was signed into law adjusting certain key terms of loans issued under the PPP. In accordance with the PPPFA, the initial deferral period may be extended from six to up to ten months and the loan maturity may be extended from two to five years. The PPPFA also provided for certain other changes, including the extent to which the loan may be forgiven.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The loan’s principal and accrued interest were forgivable to the extent that the Company initially qualified for the loan and the proceeds were used for eligible purposes, subject to certain limitations, and that the Company maintains its payroll levels over a twenty-four-week period following the loan date.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As the legal form of the Promissory Note was a debt obligation, the Company accounted for it as debt under Accounting Standards Codification (ASC) 470, Debt and recorded a liability of $781,800 in the consolidated balance sheet upon receipt of the loan proceeds.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Company applied for forgiveness, and on November 20, 2020, we received confirmation from our bank that the Promissory Note was forgiven by the SBA. The loan balance plus accrued interest of $786,889 was recorded as a gain on extinguishment of debt in the December 31, 2020 consolidated statement of operations.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The SBA has created an audit safe harbor for any PPP loan borrower that, together with its affiliates, received PPP loans with an original amount of less than $2 million. The safe harbor is designed to protect a small borrower from a PPP audit based on its good faith certification. However, the government may still decide to audit a PPP loan for other purposes, such as possible misuse of PPP funds. The Company has not been notified of an audit by the SBA.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We do not expect to pay any significant federal or state income tax for 2021 because of losses recorded during the three months ended March 31, 2021 and net operating loss carry forwards from prior years. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” that some component or all the benefits of deferred tax assets will not be realized. As of March 31, 2021, we maintained a full valuation allowance for all deferred tax assets. Based on these requirements, no provision or benefit for income taxes has been recorded. There were no recorded unrecognized tax benefits at the end of the reporting period.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Tax Cuts and Jobs Act (the “Act”)
was signed into law on December 22, 2017. Among its numerous changes to the Internal Revenue Code, the Act reduces U.S. corporate rates
from 35% to 21%. Additionally, the Act limits the use of net operating loss carry backs, however any future net operating losses will
instead be carried forward indefinitely. Net operating losses generated from January 1, 2018 are limited to offset 80% of current income,
with the remainder of the net operating loss continuing to carry forward indefinitely. Net operating losses incurred before January 1,
2018 are not subject to the 80% limitations and will begin to expire in 2029. Based on an initial assessment of the Act, the Company
believes that the most significant impact on the Company’s consolidated financial statements will be limitations in tax deductions
on interest expense. Under the Act, interest deductions disallowed from current income will carryforward indefinitely. The Act did not
impact management’s valuation allowance position.</p>

September 8, 2009, we entered into a Commercial Lease Agreement (the “Lease”) for 10,578 square feet of office and warehouse
space expiring on June 30, 2015. On March 4, 2020, we entered into the Fourth Amendment to Commercial Lease Agreement (the “Lease
Extension”), wherein we extended the Lease through August 31, 2025.  The Lease Extension contains a renewal provision under
which the Lease has been extended for an additional five-year period under the same terms and conditions of the original Lease Agreement.
Management has identified this extension as a reassessment event, as we have elected to exercise the Lease Extension option even though
the Company had previously determined that it was not reasonably certain to do so.</font></p>

and lease liability. The reassessment is based on the remaining lease term and lease payments. The Company has further concluded that
the Lease Extension has no effects on the classification of the Lease. Rent expense for the three months ended March 31, 2021 and 2020
was $73,472 and $78,369, respectively.</font></p>

The Black-Scholes Model requires the use of several assumptions including volatility of the stock price, the weighted average risk-free interest rate, and the weighted average term of the Warrant.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The risk-free interest rate assumption is based upon observed interest rates on zero coupon U.S. Treasury bonds whose maturity period is appropriate for the term of the Warrants and is calculated by using the average daily historical stock prices through the day preceding the grant date. Estimated volatility is a measure of the amount by which our stock price is expected to fluctuate each year during the expected life of the award. Our estimated volatility is an average of the historical volatility of our stock prices (and that of peer entities whose stock prices were publicly available) over a period equal to the expected life of the awards. Where appropriate we used the historical volatility of peer entities due to the lack of sufficient historical data of our stock price during 2007-2009.</p>

Pursuant to the terms of the HealthCor Purchase Agreement, we sold and issued Senior Secured Convertible Notes to HealthCor in the principal amount of $9,316,000 and $10,684,000, respectively (collectively the “2011 HealthCor Notes”). The 2011 HealthCor Notes have a maturity date of April 20, 2021. We also issued Warrants to HealthCor for the purchase of an aggregate of up to 5,488,456 and 6,294,403 shares, respectively, of our Common Stock at an exercise price of $1.40 per share (collectively the “2011 HealthCor Warrants”). So long as no event of default has occurred, the outstanding principal balances of the 2011 HealthCor Notes accrue interest from April 21, 2011 through April 20, 2016 (the “First Five-Year Note Period”) at the rate of 12.5% per annum, compounding quarterly and shall be added to the outstanding principal balances of the 2011 HealthCor Notes on the last day of each calendar quarter. Interest accruing from April 21, 2016 through April 20, 2021 (the “Second Five Year Note Period”) at a rate of 10% per annum, compounding quarterly, may be paid quarterly in arrears in cash or, at our option, such interest may be added to the outstanding principal balances of the 2011 HealthCor Notes on the last day of each calendar quarter. For the period from April 21, 2016 through September 30, 2018 interest has been added to the outstanding principal balance. Pursuant to the terms of the Ninth Amendment, the accrual of interest has been suspended after September 30, 2018. From the date any event of default occurs, the interest rate, then applicable, shall be increased by five percent (5%) per annum. HealthCor has the right, upon an event of default, to declare due and payable any unpaid principal amount of the 2011 HealthCor Notes then outstanding, plus previously accrued but unpaid interest and charges, together with the interest then scheduled to accrue (calculated at the default rate described in the immediately preceding sentence) through the end of the First Five Year Note Period or the Second Five Year Note Period, as applicable. Subject to the terms of the Ninth Amendment as discussed below, HealthCor’s ability to convert any portion of the outstanding and unpaid accrued interest on and principal balances of the 2011 HealthCor Notes into fully paid and nonassessable shares of our Common Stock has been eliminated. The warrants issued with this Note were cancelled with the Ninth-Amendment dated July 10, 2018. </p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">When issuing debt or equity securities convertible into common stock at a discount to the fair value of the common stock at the date the debt or equity financing is committed, a company is required to record a beneficial conversion feature (“BCF”) charge. We had three separate issuances of equity securities convertible into common stock that qualify under this accounting treatment, (i) the 2011 HealthCor Notes, (ii) the 2012 HealthCor Notes and (iii) the 2014 HealthCor Notes. Because the conversion option and the 2011 HealthCor Warrants on the 2011 HealthCor Notes were originally classified as a liability when issued due to the down round provision and the removal of the provision requiring liability treatment, and subsequently reclassified to equity on December 31, 2011 when the 2011 HealthCor Notes were amended, only the accrued interest capitalized as payment in kind ("PIK") since reclassification qualifies under this accounting treatment. We recorded an aggregate of $1,166,558 and $1,062,037 in interest for the three months ended March 31, 2021 and 2020, respectively, related to these transactions. For the three months ended March 31, 2021 and 2020, we recorded $721,825 and $686,927, respectively, of PIK related to the notes included in the HealthCor Purchase Agreement. The face amount of the 2012 HealthCor Notes, 2014 HealthCor Notes, the Fifth Amendment Notes and the Eighth Amendment Notes and all accrued PIK interest also qualify for BCF treatment as discussed above. Under the accounting standards, we determined that the restructuring of the HealthCor notes, pursuant to the terms of the Ninth Amendment, resulted in a troubled debt restructuring. As the future cash flows were greater than the carrying amount of the debt at the date of the amendment, we accounted for the change prospectively using the new effective interest rate. During the three months ended March 31, 2021 and 2020, we recorded a BCF of $0 and $0, respectively. </p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As Warrants were issued with the Fifth Amendment Notes, the proceeds were allocated to the instruments based on relative fair value as the warrants did not contain any features requiring liability treatment and therefore were classified as equity. The value allocated to the Fifth Amendment Warrants was $1,093,105, which was recorded as debt discount with the credit to additional paid in capital. We recorded an aggregate of $50,410 and $31,636 in interest for the three months ended, respectively, related to the Fifth Amendment Notes and Fifth Amendment Warrants. The Sixth Amendment Warrants also did not contain features requiring liability accounting and were recorded at fair value on the date of issuance with the offsetting credit recorded in equity. The value allocated to the Ninth Amendment Warrants was $378,000, which was recorded as debt costs with the credit to additional paid in capital. We recorded an aggregate of $14,451 and $14,451 in interest expense for the three months ended March 31, 2021 and 2020, respectively. The Eighth Amendment Warrants also did not contain features requiring liability accounting and were recorded at fair value on the date of issuance with the offsetting credit recorded in equity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Accounting standards require management to evaluate whether the Company can continue as a going concern for a period of one year after the date of the filing of this Form 10-Q (“evaluation period”). In evaluating the Company’s ability to continue as a going concern, Management considers the conditions and events that raise substantial doubt about the Company’s ability to continue as a going concern for a period of twelve months after the Company issues its financial statements. For the period ended March 31, 2021, Management considers the Company’s current financial condition and liquidity sources, including current funds available, forecasted future cash flows, and the Company’s conditional and unconditional obligations due before May 24, 2022.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Company is subject to risks like those of healthcare technology companies whereby revenues are generated based on both on a sales-based and subscription-based business model such as dependence on key individuals, uncertainty of product development, generation of revenues, positive cash flow, dependence on outside sources of capital, risks associated with research, development, and successful testing of its products, successful protection of intellectual property, ability to maintain and grow its customer base, and susceptibility to infringement on the proprietary rights of others. The attainment of profitable operations is dependent on future events, including obtaining adequate financing to fulfill the Company’s growth and operating activities and generating a level of revenues adequate to support the Company’s cost structure.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Company has experienced net losses and significant cash outflows from cash used in operating activities over the past years. As of and for the three months ended March 31, 2021, the Company had an accumulated deficit of approximately $190,300,000, income from operations of approximately $226,000, net cash provided by operating activities of $47,000, and an ending cash balance of $355,439.</p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p>
<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As of March 31, 2021 and 2020, the Company
had cash and a working capital deficit of approximately $27,600,000 consisting primarily of notes payables.  Management has
evaluated the significance of the conditions described above in relation to the Company’s ability to meet its obligations and
concluded that, without additional funding, the Company will not have sufficient funds to meet its obligations within one year from
the date the condensed consolidated financial statements were issued. While management will look to continue funding operations by

Under the accounting standards, we determined that the restructuring of the Tranche One Loan resulted in a troubled debt restructuring. As the future cash flows were greater than the carrying amount of the debt at the date of the amendment, we accounted for the change prospectively using the new effective interest rate. Also on May 15, 2019, upon the execution of the Fifth PDL Credit Agreement Amendment, (i) the Company sold and issued the Tranche Three Lenders term notes in the aggregate principal amount of $200,000, payable in accordance with the terms of the PDL Credit Agreement (the “Tranche Three Loans”), $150,000 from Mr. Johnson and $50,000 from Dr. Higgins, and (ii) the Company issued a warrant for the purchase of 250,000 shares of Common Stock, with an exercise price per share equal to $0.03 (subject to adjustment as described therein) and an expiration date of May 15, 2029 (the “Tranche Three Loan Warrant”), to Dr. Higgins in connection with his Tranche Three Loan.

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contracts with our customers are typically structured similarly and include various combinations of our products, software solutions, and related services. Determining whether the various contract promises are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment.</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contract transaction price is allocated to distinct performance obligations using estimated standalone selling price. We determine standalone selling price maximizing observable inputs such as standalone sales, competitor standalone sales, or substantive renewal prices charged to customers when they exist.  In instances where standalone selling price is not observable, we utilize an estimate of standalone selling price. Such estimates are derived from various methods that include cost plus margin, and historical pricing practices. Judgment may be required to determine standalone selling prices for each performance obligation and whether it depicts the amount we expect to receive in exchange for the related good or service.</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contract modifications occur when we and our customers agree to modify existing customer contracts to change the scope or price (or both) of the contract or when a customer terminates some, or all, of the existing services provided by us. When a contract modification occurs, it requires us to exercise judgment to determine if the modification should be accounted for as a separate contract, the termination of the original contract and creation of a new contract, a cumulative catch-up adjustment to the original contract, or a combination.   </p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contracts with our customers include a limited warranty on our products covering materials, workmanship, or design for the duration of contract.  We do not offer paid additional extended or lifetime warranty packages.  We determined the limited warranty in our contract is not a distinct performance obligation.  We do not believe our estimates of warranty costs to be significant to our determination of revenue recognition and, therefore, did not reserve for warranty costs.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We calculate earnings per share (“EPS”) in accordance with GAAP, which requires the computation and disclosure of two EPS amounts, basic and diluted. Basic EPS is computed based on the weighted average number of common shares outstanding during the period. Diluted EPS is computed based on the weighted average number of common shares outstanding plus all potentially dilutive common shares outstanding during the period under the treasury stock method. Such potential dilutive common shares consist of stock options, warrants to purchase our Common Stock (the “Warrants”) and convertible debt. Potential common shares totaling approximately 211,000,000 and 174,000,000 at March 31, 2021 and 2020, respectively, have been excluded from the diluted earnings per share calculation as they are anti-dilutive due to our reported net loss.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0in; text-align: justify">Customer contract fulfillment typically involves multiple procurement promises which may include various equipment, software subscription, project-related installation and training services, and support.  We allocate the transaction price to each performance obligations based on estimated relative standalone selling price.  Revenue is then recognized for each performance obligation upon transferring control of the hardware, software, and services to the customer an in an amount that reflects the consideration we expect to receive and the estimated benefit the customer receives over the term of the contract.</p>

<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contracts with our customers are typically structured similarly and include various combinations of our products, software solutions, and related services. Determining whether the various contract promises are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment.</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contract transaction price is allocated to distinct performance obligations using estimated standalone selling price. We determine standalone selling price maximizing observable inputs such as standalone sales, competitor standalone sales, or substantive renewal prices charged to customers when they exist.  In instances where standalone selling price is not observable, we utilize an estimate of standalone selling price. Such estimates are derived from various methods that include cost plus margin, and historical pricing practices. Judgment may be required to determine standalone selling prices for each performance obligation and whether it depicts the amount we expect to receive in exchange for the related good or service.</p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contract modifications occur when we and our customers agree to modify existing customer contracts to change the scope or price (or both) of the contract or when a customer terminates some, or all, of the existing services provided by us. When a contract modification occurs, it requires us to exercise judgment to determine if the modification should be accounted for as a separate contract, the termination of the original contract and creation of a new contract, a cumulative catch-up adjustment to the original contract, or a combination.   </p>
<p style="font: 10pt Times New Roman, Times, Serif; text-align: justify">Contracts with our customers include a limited warranty on our products covering materials, workmanship, or design for the duration of contract.  We do not offer paid additional extended or lifetime warranty packages.  We determined the limited warranty in our contract is not a distinct performance obligation.  We do not believe our estimates of warranty costs to be significant to our determination of revenue recognition and, therefore, did not reserve for warranty costs.</p>
