NOTE 1 – BASIS OF PRESENTATION AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS Interim Financial Statements The accompanying unaudited interim condensed consolidated financial statements of CareView Communications, Inc. ("CareView", the "Company", "we", "us" or "our") have been prepared in accordance with generally accepted 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, 2021 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 unaudited 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, 2021 as filed with the SEC on March 31, 2022. Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 (“ASC 606”). For our subscription service contracts, we have employed the practical expedient discussed in ASC 606-10-55-18 related to invoicing as we have the right to consideration from our customers in the amount that corresponds directly with the value to the customer of our performance completed to date and therefore, we recognize revenue upon invoicing as further discussed below. In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which we expect to be entitled to receive in exchange for these goods or services. The provisions of ASC 606 include a five-step process by which we determine revenue recognition, depicting the transfer of goods or services to customers in amounts reflecting the payment to which we expect to be entitled in exchange for those goods or services. ASC 606 requires us to apply the following steps: (1) identify the contract with the customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy the performance obligation. For those customers for which we are required to collect sales taxes, we record such sales taxes on a net basis which has no effect on the amount of revenue or expenses recognized as the sales taxes are a flow through to the taxing authority. We enter into contracts with customers that may provide multiple combinations of our products, software solutions, and other related services, which are generally capable of being distinct and accounted for as separate performance obligations. Performance obligations that are not distinct at contract inception are combined. 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 obligation 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 and in an amount that reflects the consideration we expect to receive and the estimated benefit the customer receives over the term of the contract.

Some customers choose to pay their subscription fee in advance. Customer payments received in advance of satisfaction of the related performance obligations are deferred as contract liabilities. These amounts are recorded as “deferred revenue” in our condensed consolidated balance sheet and recognized into revenues over time. Our sales-based contract payment arrangements with our customers typically include an initial equipment payment due upon signing of the contract and subsequent payments when certain performance obligations are completed. Customer payments received in advance of satisfaction of related performance obligations are deferred as contract liabilities. These amounts are recorded as “deferred revenue” in our condensed consolidated balance sheet and recognized into revenues as either a point in time or over time.

Determining whether the various contract promises are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. 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. 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. 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. Leases The Company has an operating lease primarily consisting of office space with a remaining lease term of 41 months. At the lease commencement date, an operating lease liability and related operating lease asset are recognized. The operating lease liabilities are calculated using the present value of lease payments. The discount rate used is either the rate implicit in the lease, when known, or our estimated incremental borrowing rate. Operating lease assets are valued based on the initial operating lease liabilities plus any prepaid rent and direct costs from executing the leases. Earnings Per Share 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 <span id="xdx_900_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_uShares_c20220101__20220331_zOEhsqEuzH87" title="Anti-dilutive common share equivalents excluded from EPS calculation">178,543,025 and <span id="xdx_90B_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_uShares_c20210101__20210331_zvdlFJ8TpeTl" title="Anti-dilutive common share equivalents excluded from EPS calculation">211,000,000 at March 31, 2022 and 2021, respectively, have been excluded from the diluted earnings per share calculation as they are anti-dilutive due to our reported net loss.

Interim Financial Statements The accompanying unaudited interim condensed consolidated financial statements of CareView Communications, Inc. ("CareView", the "Company", "we", "us" or "our") have been prepared in accordance with generally accepted 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, 2021 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 unaudited 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, 2021 as filed with the SEC on March 31, 2022.

Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 (“ASC 606”). For our subscription service contracts, we have employed the practical expedient discussed in ASC 606-10-55-18 related to invoicing as we have the right to consideration from our customers in the amount that corresponds directly with the value to the customer of our performance completed to date and therefore, we recognize revenue upon invoicing as further discussed below. In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which we expect to be entitled to receive in exchange for these goods or services. The provisions of ASC 606 include a five-step process by which we determine revenue recognition, depicting the transfer of goods or services to customers in amounts reflecting the payment to which we expect to be entitled in exchange for those goods or services. ASC 606 requires us to apply the following steps: (1) identify the contract with the customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy the performance obligation. For those customers for which we are required to collect sales taxes, we record such sales taxes on a net basis which has no effect on the amount of revenue or expenses recognized as the sales taxes are a flow through to the taxing authority. We enter into contracts with customers that may provide multiple combinations of our products, software solutions, and other related services, which are generally capable of being distinct and accounted for as separate performance obligations. Performance obligations that are not distinct at contract inception are combined. 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 obligation 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 and in an amount that reflects the consideration we expect to receive and the estimated benefit the customer receives over the term of the contract. Generally, we recognize revenue under each of our performance obligations as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Arial, Helvetica, Sans-Serif; width: 100%; margin-top: 0;

Determining whether the various contract promises are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. 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. 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. 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.

Leases The Company has an operating lease primarily consisting of office space with a remaining lease term of 41 months. At the lease commencement date, an operating lease liability and related operating lease asset are recognized. The operating lease liabilities are calculated using the present value of lease payments. The discount rate used is either the rate implicit in the lease, when known, or our estimated incremental borrowing rate. Operating lease assets are valued based on the initial operating lease liabilities plus any prepaid rent and direct costs from executing the leases.

Earnings Per Share 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 <span id="xdx_900_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_uShares_c20220101__20220331_zOEhsqEuzH87" title="Anti-dilutive common share equivalents excluded from EPS calculation">178,543,025 and <span id="xdx_90B_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_pid_uShares_c20210101__20210331_zvdlFJ8TpeTl" title="Anti-dilutive common share equivalents excluded from EPS calculation">211,000,000 at March 31, 2022 and 2021, respectively, have been excluded from the diluted earnings per share calculation as they are anti-dilutive due to our reported net loss.

Reclassification Certain amounts reported in prior years in the financial statements have been reclassified to conform to the current year's presentation.

NOTE 2 – GOING CONCERN, LIQUIDITY AND MANAGEMENT'S PLAN 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 three months ended March 31, 2022, 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 within 12 months of the date these financial statements are issued. The Company is subject to risks like those of healthcare technology companies whereby revenues are generated based on both sales-based and subscription-based models, which assume 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. 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, 2022, the Company had an accumulated deficit of approximately $200,200,000, loss from operations of approximately $323,000, net cash provided by operating activities of $178,896 and an ending cash balance of $764,707. As of March 31, 2022, the Company had cash and a working capital deficit of $31,827,363 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 unaudited condensed consolidated financial statements were issued. While management will look to continue funding operations by increased sales volumes and raising additional capital from sources such as sales of its debt or equity securities or loans to meet operating cash requirements, there is no assurance that management’s plans will be successful. As of March 8, 2022, the company extended HealthCor 2011 and 2012 notes through April 20, 2023 by entering Allonge No.4, and we issued warrants to purchase an aggregate of <span id="xdx_905_eus-gaap--ClassOfWarrantOrRightNumberOfSecuritiesCalledByWarrantsOrRights_iI_pid_uShares_c20220308__us-gaap--ClassOfWarrantOrRightAxis__custom--HealthCorAllongeNo4WarrantsMember_zvz2aLxilYKd" title="Number of warrants issued">3,000,000 shares of our Common Stock at an exercise price per share equal to $<span id="xdx_900_eus-gaap--ClassOfWarrantOrRightExercisePriceOfWarrantsOrRights1_iI_pid_uUSDPShares_c20220308__us-gaap--ClassOfWarrantOrRightAxis__custom--HealthCorAllongeNo4WarrantsMember_zhqOI79I72yc" title="Warrant exercise price (in dollars per share)">0.09 per share. Management continues to monitor the immediate and future cash flows needs of the company in a variety of ways which include forecasted net cash flows from operations, capital expenditure control, new inventory orders, debt modifications, increases sales outreach, streamlining and controlling general and administrative costs, competitive industry pricing, sale of equities, debt conversions, new product or services offerings, and new business partnerships. The Company’s net losses, cash outflows, and working capital deficit raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. This basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of liabilities in the normal course of business. A successful transition to attaining profitable operations is dependent upon achieving a level of positive cash flows adequate to support the Company’s cost structure.

NOTE 3 – STOCKHOLDERS’ EQUITY Warrants to Purchase Common Stock of the Company We use the Black-Scholes-Merton option pricing model (“Black-Scholes Model”) to determine the fair value of Warrants (except Warrants issued to HealthCor in 2011 (the “2011 HealthCor Warrants”) as discussed in NOTE 11 and the warrants issued in connection with a private placement completed in April 2013 (“Private Placement Warrants”). 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. 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. On April 20, 2021, we issued <span id="xdx_90C_eus-gaap--ClassOfWarrantOrRightNumberOfSecuritiesCalledByWarrantsOrRights_iI_pid_uShares_c20210420__us-gaap--ClassOfWarrantOrRightAxis__custom--HealthCorPartnersWarrantsMember_z3ODkaEdzpac" title="Number of warrants issued">931,600 and <span id="xdx_906_eus-gaap--ClassOfWarrantOrRightNumberOfSecuritiesCalledByWarrantsOrRights_iI_pid_uShares_c20210420__us-gaap--ClassOfWarrantOrRightAxis__custom--HealthCorHybridWarrantsMember_zzmgdFJ0rTVf" title="Number of warrants issued">1,068,400 warrants to purchase our Common Stock at an exercise price of $<span id="xdx_90C_eus-gaap--ClassOfWarrantOrRightExercisePriceOfWarrantsOrRights1_iI_pid_uUSDPShares_c20210420__us-gaap--ClassOfWarrantOrRightAxis__custom--HealthCorWarrantsMember_zIl6DPG6RqJk" title="Warrant exercise price (in dollars per share)">0.23 per share to HealthCor Partners and HealthCor Hybrid, respectively.

The estimate of forfeitures is to be recorded at the time of grant and revised in subsequent periods if actual forfeitures differ from the estimates. We have not included an adjustment to our stock-based compensation expense based on the nominal amount of the historical forfeiture rate. We do, however, revise our stock-based compensation expense based on actual forfeitures during each reporting period.

NOTE 9 – INCOME TAXES 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 2022 because of the losses recorded during the three months ended March 31, 2022 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, 2022, 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. 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 <span id="xdx_90B_eus-gaap--EffectiveIncomeTaxRateReconciliationAtFederalStatutoryIncomeTaxRate_pid_dp_uPure_c20170101__20171231__us-gaap--IncomeTaxAuthorityAxis__us-gaap--InternalRevenueServiceIRSMember_zHi7Xqnqxszl" title="Percentage of corporate tax rate">35% to <span id="xdx_90E_eus-gaap--EffectiveIncomeTaxRateReconciliationAtFederalStatutoryIncomeTaxRate_pid_dp_uPure_c20180101__20181231__us-gaap--IncomeTaxAuthorityAxis__us-gaap--InternalRevenueServiceIRSMember_z5sxG3OspKd9">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 <span id="xdx_90F_ecustom--PercentageOfOperatingLossCarryforwardsLimitation_iI_pid_dp_uPure_c20180102__us-gaap--IncomeTaxAuthorityAxis__us-gaap--InternalRevenueServiceIRSMember_z95bLYBKgUL" title="Percentage of operating loss carryforwards limitation">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 unaudited condensed 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. The effective tax rate for the three months ended March 31, 2022 was different from the federal statutory rate due primarily to change in the valuation allowance and nondeductible interest and amortization expense.

("PDL"), as administrative agent and lender ("the Lender") (the "PDL Credit Agreement"). Under the PDL Credit Agreement the Lender made available to us up to $<span id="xdx_904_eus-gaap--DebtInstrumentUnusedBorrowingCapacityAmount_iI_pn6n6_c20150626__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember_zmqrfB9ofnd3" title="Amount available under credit agreement">40 million in two tranches of $<span id="xdx_908_eus-gaap--DebtInstrumentUnusedBorrowingCapacityAmount_iI_pn6n6_c20150626__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--LongtermDebtTypeAxis__custom--TrancheOneMember_z09jI28LVeCi" title="Amount available under credit agreement">20 million each. Tranche One was funded on October 8, 2015 (the "Tranche One Loan"). Pursuant to the terms of the PDL Credit Agreement and having not met the Tranche Two Milestones by July 26, 2017, the Tranche Two funding was terminated in full. From October 8, 2015 through May 14, 2019, the outstanding borrowings under the Tranche One Loan bore interest at the rate of <span id="xdx_90F_eus-gaap--DebtInstrumentInterestRateDuringPeriod_pid_dp_uPure_c20151008__20190513__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--LongtermDebtTypeAxis__custom--TrancheOneMember_zBBmue0Q90Wc" title="Interest rate during period">13.5% per annum, payable quarterly.

On January 31, 2021, the Company, the Borrower, the Subsidiary Guarantor, the Lender and the Tranche Three Lenders entered into a Twenty-Third Amendment to Modification Agreement (the “Twenty-Third Modification Agreement Amendment”), pursuant to which the parties agreed to amend the Modification Agreement to provide that the dates on which the Lender may elect, in the Lender’s sole discretion, to terminate the Modification Period would be July 31, 2018 and January 31, 2021 (with each such date permitted to be extended by the Lender in its sole discretion); and that the Borrower’s (i) interest payments that would otherwise be due under the Credit Agreement on December 31, 2018, March 31, 2019, June 30, 2019, September 30, 2019, December 31, 2019, March 31, 2020, June 30, 2020, September 30, 2020, and October 7, 2020 and (ii) payments for principal and for any other Obligations then outstanding under the Tranche One Loan and the Tranche Three Loans that would otherwise be due under the Credit Agreement on October 7, 2020, would each be deferred until May 31, 2021 (the end of the extended Modification Period) and that such deferrals would be a Covered Event. The Company has evaluated the Twenty-Third Modification Agreement Amendment and as the effective borrowing rate under the restructured agreement is less than the effective borrowing rate on the old agreement, a concession is deemed to have been granted under ASC 470-60-55-10. As a concession has been granted, the agreement is to be accounted for as a troubled debt restructuring by debtors (TDR) under ASC 470-60. On May 25, 2021, the Company, the Borrower, the Subsidiary Guarantor, the Lender and the Tranche Three Lenders entered into a Twenty-Fourth Amendment to Modification Agreement (the “Twenty-Fourth Modification Agreement Amendment”), pursuant to which the parties agreed to amend the Modification Agreement to provide that the dates on which the Lender may elect, in the Lender’s sole discretion, to terminate the Modification Period would be July 31, 2018 and November 30, 2021 (with each such date permitted to be extended by the Lender in its sole discretion); and that the Borrower’s (i) interest payments that would otherwise be due under the Credit Agreement on December 31, 2018, March 31, 2019, June 30, 2019, September 30, 2019, December 31, 2019, March 31, 2020, June 30, 2020, September 30, 2020, October 7, 2020, and (ii) payments for principal and for any other Obligations then outstanding under the Tranche One Loan and the Tranche Three Loans that would otherwise be due under the Credit Agreement on October 7, 2020, would each be deferred until November 30, 2021 (the end of the extended Modification) and that such deferrals would be a Covered Event. The Company has evaluated the Twenty-Fourth Modification Agreement Amendment and as the effective borrowing rate under the restructured agreement is less than the effective borrowing rate on the old agreement, a concession is deemed to have been granted under ASC 470-60-55-10. As a concession has been granted, the agreement is to be accounted for as a troubled debt restructuring by debtors (TDR) under ASC 470-60. On November 29, 2021, the Company, the Borrower, the Subsidiary Guarantor, the Lender and the Tranche Three Lenders entered into a Twenty-Fifth Amendment to Modification Agreement (the “Twenty-Fifth Modification Agreement Amendment”), pursuant to which the parties agreed to amend the Modification Agreement to provide that the dates on which the Lender may elect, in the Lender’s sole discretion, to terminate the Modification Period would be July 31, 2018 and June 30, 2022 (with each such date permitted to be extended by the Lender in its sole discretion); and that the Borrower’s (i) interest payments that would otherwise be due under the Credit Agreement on December 31, 2018, March 31, 2019, June 30, 2019, September 30, 2019, December 31, 2019, March 31, 2020, June 30, 2020, September 30, 2020 and October 7, 2020 and (ii) payments for principal and for any other Obligations then outstanding under the Tranche One Loan and the Tranche Three Loans that would otherwise be due under the Credit Agreement on October 7, 2020, would each be deferred until June 30, 2022 (the end of the extended Modification) and that such deferrals would be a covered event. The Company has evaluated the Twenty-Fifth Modification Agreement Amendment and as the effective borrowing rate under the restructured agreement is less than the effective borrowing rate on the old agreement, a concession is deemed to have been granted under ASC 470-60-55-10. As a concession has been granted, the agreement is to be accounted for as a troubled debt restructuring by debtors (TDR) under ASC 470-60. Accounting Treatment In connection with the PDL Credit Agreement, as amended, we issued the PDL Warrant to the Lender. The fair value of the PDL Warrant at issuance was $<span id="xdx_906_ecustom--DeferredIssuanceCosts_iI_pp0p0_c20220331__us-gaap--CreditFacilityAxis__custom--PDLBioPharmaIncMember__us-gaap--ClassOfWarrantOrRightAxis__custom--WarrantPurchaseAgreementMember_z3bHHD4m9ME8" title="Deferred issuance costs">1,600,000 which has been recorded as deferred issuance costs in the accompanying unaudited condensed consolidated financial statements. As of March 31, 2022, the Amended PDL Warrant has not been exercised. As of March 31, 2022, the Company and Lender had entered into twenty-fifth amendments to the PDL Modification Agreement (as detailed above), resulting in restructuring of the PDL Credit Agreement and the accounting treatment of the related costs. Under debt modification/troubled debt guidance, we determined that the first of the eight amendments had no cash flow impact, and therefore, had no impact on accounting. Amendments nine through ten qualified for modification accounting, while the final thirteen amendments qualified for troubled debt restructuring accounting. As appropriate, we expensed the legal costs paid to third parties. For the three months ended March 31, 2022 and 2021, pursuant to the terms of the PDL Modification Agreement, as amended, $775,000 and $775,000, respectively, was recorded as interest expense on the accompanying unaudited condensed consolidated financial statements.

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 $406,760 and $1,166,558 in interest for the three months ended March 31, 2022 and 2021, respectively, related to these transactions. For the three months ended March 31, 2022 and 2021, we recorded $806,728 and $721,825, 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 for three months ended March 31, 2022. Warrants were issued with the Fourth, Fifth, Eighth, Ninth, and Allonge 3 Amendment Notes and 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. At each amendment date, the warrants were recorded as debt discount, as a reduction of the net carrying amount of the debt. The debt discounts are amortized into interest expense each period under the effective interest method. The value allocated to the Ninth Amendment Warrants was $378,000. The value allocated to the Allonge 3 Amendment Warrants was $420,000. Warrants were issued with Allonge 4 Amendment Notes and the proceeds were allocated to the instruments based on relative fair value as the warrants did not contain any features requiring lia0bility treatment and therefore were classified as equity. At each amendment date, the warrants were recorded as debt discount, as a reduction of the net carrying amount of the debt. The debt discounts are amortized into interest expense each period under the effective interest method. The value allocated to the Allonge 4 Amendment Warrants was $240,000.

NOTE 13 – LEASE Under ASC Topic 842, Leases (“ASC 842”), operating lease expense is generally recognized evenly over the term of the lease. The Company has an operating lease primarily consisting of office space with remaining lease term of 41 months (Lease through August 31, 2025). On 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. The Company has reassessed the discount rate at the remeasurement date, at 14.8% and the Company has remeasured its ROU asset and lease liability on our balance sheet using the discount rate that applies as of the date of the reassessment event to remeasure its Operating lease asset 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, 2022 and 2021 was $82,706 and $72,684, respectively. Lease Position Operating lease asset and liability for our operating lease were recorded in the condensed consolidated balance sheet as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif;
