Note 1 - Business Organization, Nature of Operations, Risks and Uncertainties and Basis of Presentation

Cell Source, Inc. (“Cell Source”, “CSI” or the “Company”) is a Nevada corporation formed on June 6, 2012 that is the parent company of Cell Source Limited (“CSL”), a wholly owned subsidiary which was founded in Israel in 2011 in order to commercialize a suite of inventions relating to certain cancer treatments. The Company is a biotechnology company focused on developing cell therapy treatments based on the management of immune tolerance. The Company’s lead prospective product is its patented Veto Cell immune system management technology, which is an immune tolerance biotechnology that enables the selective blocking of immune responses. CSL’s Veto Cell immune system management technology is based on technologies patented, owned, and licensed to CSL by Yeda Research and Development Company Limited, an Israeli corporation ~~("Yeda"~~(“Yeda”) (see Note 8 ~~Related Party Transactions~~ – Commitments and Contingencies). The Company’s target indications include: lymphoma, leukemia and multiple myeloma through the facilitation of safer and more accessible stem cell (e.g. bone marrow) transplantation acceptance, treatment of end stage kidney disease and other non-malignant organ diseases through improved organ transplantation (broadened donor pool, reduced dependence on post-transplant anti-rejection therapy), and ultimately treating a variety of cancers and non-malignant diseases.

In March 2020, the World Health Organization declared ~~the outbreak of~~COVID-19, a novel strain of coronavirus, ~~(“COVID-19”) as~~ a ~~pandemic which~~pandemic. During 2020 and continuing into 2021, the global economy has been, and continues to ~~spread throughout~~be, affected by COVID-19. While the ~~United States.~~Company continues to see signs of economic recovery as certain governments began to gradually ease restrictions, provide economic stimulus and vaccine distribution accelerated, the rate of recovery on a global basis has been affected by resurgence of the virus or its variants in certain jurisdictions causing reinstatement of restrictions in certain jurisdictions. The Company ~~is closely monitoring~~continues to monitor the ~~outbreak~~effects of COVID-19 and its impact on the Company’s operations, financial position, cash flows and its industry in general. The Company considered the impact of COVID-19 on its business and operational assumptions and estimates, and determined there were no material adverse impacts on the Company’s results of operations and financial position at ~~June 30, 2020.~~March 31, 2021.

The full extent of ~~COVID-19~~the future ~~impacts~~impact of COVID-19 on the Company’s operations and financial condition is uncertain. ~~A prolonged~~Accordingly, COVID-19 ~~outbreak~~ could have a material adverse ~~impact~~effect on the Company’s business, results of operations, financial condition and ~~liquidity,~~prospects during 2021 and beyond, including the timing and ability of the Company to initiate and/or complete current and/or future preclinical studies and/or clinical trials, disrupt the Company’s regulatory activities, and/or have other adverse effects on the Company’s clinical development. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, such statements include all adjustments (consisting only of normal recurring items) which are considered necessary for a fair presentation of the condensed consolidated financial position of the Company as of ~~June 30, 2020~~March 31, 2021 and the condensed consolidated results of its operations and cash flows for the ~~six~~three months ended ~~June 30, 2020~~March 31, 2021 and ~~2019.~~2020. The results of operations for the three ~~and six~~ months ended ~~June 30, 2020~~March 31, 2021 are not necessarily indicative of the operating results for the full year ending December 31, ~~2020~~2021 or any other period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related disclosures of the Company as of December 31, ~~2019~~2020 and for the year then ended which were included in the ~~Company's~~Company’s Annual Report on Form 10-K that was filed with the Securities and Exchange Commission (“SEC”) on ~~March 30, 2020.~~April 15, 2021.

During the ~~six~~three months ended ~~June 30, 2020,~~March 31, 2021, the Company had not generated any revenues, had a net loss of approximately ~~$1,978,000~~$1,525,000 and had used cash in operations of approximately ~~$1,154,000.~~$1,114,000. As of ~~June 30, 2020,~~March 31, 2021, the Company had a working capital deficiency of approximately ~~$6,528,000~~$9,142,000 (including $1,558,000 of notes payable past due) and an accumulated deficit of approximately ~~$23,124,000.~~$27,231,000. Subsequent to ~~June 30, 2020~~March 31, 2021 and as more fully described in Note ~~10,~~ 9 – Subsequent Events,, the Company received proceeds of ~~$603,355 through the sale of 80,466 shares of Series A Convertible Preferred Stock at $7.50 per share and net proceeds of $497,500~~$100,000 through the issuance of a convertible ~~note payable in the principal amount of $555,556.~~notes. These conditions raise substantial doubt about the Company’s ability to continue as a going concern ~~within twelve months~~for at least one year from the date these financial statements are issued.

The Company is currently funding its operations on a month-to-month basis. While there can be no assurance that it will be successful, the Company is in active negotiations to raise additional capital. The Company’s primary sources of operating funds since inception have been equity and debt financings. Management’s plans include continued efforts to raise additional capital through debt and equity financings. There is no assurance that these funds will be sufficient to enable the Company to fully complete its development activities or attain profitable operations. If the Company is unable to obtain such additional financing on a timely basis or, notwithstanding any request the Company may make, if the Company’s debt holders do not agree to convert their notes into equity or extend the maturity dates of their notes, the Company may have to curtail its development, marketing and promotional activities, which would have a material adverse effect on the Company’s business, financial condition and results of operations, and ultimately the Company could be forced to discontinue its operations and liquidate.

The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the financial statements do not necessarily purport to represent realizable or settlement values. The condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.

Since the date of the Annual Report on Form 10-K for the year ended December 31, ~~2019,~~2020, there have been no material changes to the Company’s significant accounting policies.

The Company computes basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities. Diluted earnings per share includes the dilution that would occur upon the exercise or conversion of all dilutive securities into common stock using the “treasury stock” and/or “if converted” methods, as applicable. ~~Weighted~~Basic weighted average shares outstanding for the three ~~and six~~ months ended ~~June 30,~~March 31, 2021 and 2020 ~~and 2019~~ includes the weighted average impact of warrants to purchase an aggregate of 0 and 2,043,835 shares of common stock because their exercise price was determined to be nominal.

The common stock equivalents associated with the following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:

[1] Convertible notes are assumed to be converted at the rate of $0.75 per common share, which is the conversion ~~price.~~price as of March 31, 2021. However, as further described in Note 5, Notes Payable, such conversion rates are subject to adjustment under certain circumstances, which may result in the issuance of common shares greater than the amount indicated.

~~Reclassifications~~[2] Excludes shares of common stock underlying convertible notes that are expected to become convertible into shares of Series B and Series C Convertible Preferred Stock since such stock had not been designated by the Company as of March 31, 2021.

Certain prior period amounts have been reclassified in order to conform to the fiscal 2020 presentation, including certain accrued liabilities that have been reclassified from accrued compensation to accrued interest as well as certain operating expenses that have been reclassified to other expenses. These reclassifications have no impact on the previously reported net loss.

During the six months ended June 30, 2020, in connection with the extension of certain convertible notes payable that previously contained a variable conversion price with no floor and, a result, triggered sequencing, the parties agreed to amend the conversion terms such that a conversion price floor of $0.75 per share was established. As a result, the Company had no remaining outstanding instruments with a variable conversion price with no floor and, accordingly, the Company reclassified derivative liabilities with an aggregate fair value of $345,830 to additional paid-in capital. See Note 6, ~~Notes Payable and Convertible Notes Payable~~ ~~for additional details.~~

The following table ~~summarizes~~provides a summary of the ~~Company’s instruments recorded~~changes in fair value, including net transfers in and/or out, of all Level 3 liabilities measured at fair value ~~as of June 30, 2020 and December~~on a recurring basis using unobservable inputs during the three months ended March 31, ~~2019:~~2021:

Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. ~~As of June 30, 2020, the~~The Company’s Level 3 liabilities shown in the above table consist of accrued obligations to issue warrants and common stock. As of December 31, 2019, the Company’s Level 3 liabilities shown in the above table consist of sequenced warrants with no price floor as the Company was unable to determine that it had sufficient authorized common stock to settle such arrangements, warrants deemed to be derivative liabilities according to the Company’s sequencing policy in accordance with ASC 815-40-35-12, the embedded conversion options within its convertible notes payable and an accrued obligation to issue warrants and common stock.

In applying the Black-Scholes option pricing model utilized in the valuation of Level 3 liabilities, the Company used the following approximate assumptions:

	For the Three Months Ended						For the Six Months Ended						For the Months Ended
	June 30,						June 30,						March 31,
	2020			2019			2020			2019			2021			2020

Risk-free interest rate		0.24% - 0.29	%		1.17% - 2.18	%		0.24% - 1.55	%		1.17% - 2.44	%		0.64%-0.92	%		0.33%-1.55	%
Expected term (years)		4.00 - 5.00			0.05 - 5.00			0.52 - 5.00			0.02 - 5.00			4.00-5.00			0.52 - 5.00
Expected volatility		110	%		110	%		110	%		110	%		90	%		110	%
Expected dividends		0.00	%		0.00	%		0.00	%		0.00	%		0.00	%		0.00	%

The expected term used is the contractual life of the instrument being valued. Since the Company’s stock does not have significant trading volume, the Company is utilizing an expected volatility based on a review of the historical volatilities, over a period of time, equivalent to the expected life of the instrument being valued, of similarly positioned public companies within its industry. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.

The following table provides a summary of the changes in fair value, including net transfers in and/or out, of all Level 3 liabilities measured at fair value on a recurring basis using unobservable inputs during the six months ended June 30, 2020:

As of ~~June 30,~~March 31, 2021 and December 31, 2020, the Company had an obligation to issue ~~150,000~~154,495 shares of common stock to service providers that had a fair value of ~~$37,500,~~$72,613, which was a component of accrued compensation on the condensed consolidated balance sheet.

See Note 7, 6 – Stockholders’ Deficiency – Stock Warrantsfor additional details associated with the issuance of warrants.

On May 6, 2020, the Company received proceeds of $100,000 through an advance. In connection with the advance, the Company issued a five-year immediately vested warrant to purchase 200,000 shares of common stock at $0.75 per share. The warrant had an issuance date relative fair value of $24,386, which was recorded as interest expense on the condensed consolidated statement of operations. On June 1, 2020, the Company repaid the advance in full.

~~On June 18, 2020, the Company paid $5,000 in partial repayment of an outstanding advance.~~

As of ~~June 30, 2020~~March 31, 2021 and through the date of this filing, notes and convertible notes payable with principal amounts totaling ~~$1,538,000~~$1,558,000 and $1,858,000, respectively, were past due and are classified as current liabilities on the condensed consolidated balance sheet as of ~~June 30, 2020.~~March 31, 2021. Such notes continue to accrue interest and all relevant penalties have been accrued as of ~~June 30, 2020.~~March 31, 2021. Of such past due notes payable, a holder of a note with principal amount of $250,000 issued a notice of default. See Note 9, 8 – Commitments and Contingencies – Litigation for additional details. The Company is in negotiations with all holders of notes payable to extend the maturity dates of such notes or to convert the principal and accrued interest into equity.

During the three months ended ~~June 30,~~March 31, 2021 and 2020, ~~and 2019,~~ the Company recorded interest expense of ~~$93,879~~$280,887 and ~~$77,673,~~$87,649, respectively, and amortization of debt discount of ~~$36,228~~$122,763 and $6,529, respectively. During the six months ended June 30, 2020 and 2019, the Company recorded interest expense of $181,528 and $188,457, respectively, and amortization of debt discount of $44,530 and $6,529,$8,302, respectively. As of ~~June 30, 2020~~March 31, 2021 and December 31, ~~2019,~~2020, the Company had ~~$697,253~~$964,122 and ~~$573,007,~~$997,244, respectively, of accrued interest (including interest in the form of warrants (see Note 4)) and penalties related to notes payable, which is included with accrued interest and accrued interest – related parties on the condensed consolidated balance sheets.

During the three months ended March 31, 2021, the Company issued convertible notes payable in the aggregate principal amount of $697,250 which have maturity dates ranging from July 7, 2021 through September 24, 2021. The notes accrue interest at 8% per annum and are convertible into the Company’s Series C Convertible Preferred Stock (the “Series C Preferred Stock”) at a conversion price of $7.50. The notes shall become convertible (i) at the holder’s option beginning on the date that the Company first issues any shares of its Series C Preferred Stock or (ii) automatically on the maturity date. It is anticipated that the Series C Preferred Stock shall convert into the Company’s common stock at a fixed rate of ten (10) shares of common stock for each share of Series C Preferred Stock. In connection with the issuances, the Company issued five-year immediately vested warrants to purchase an aggregate of 557,800 shares of common stock at an exercise price $1.25 per share. The warrants had an issuance date relative fair value of $114,617 which will be amortized over the term of the notes.

On January 3, 2020, a third party repaid a convertible note in full on behalf of the Company, which payment included a prepayment penalty for an aggregate total payment of $100,896 (principal and interest of $68,000 and $32,896, respectively), which was fully repaid by the Company as of June 30, 2020. The Company determined the transaction was a note extinguishment and recorded a loss on extinguishment of $1,441 in the condensed consolidated statements of operations.

~~On January 10, 2020,~~28, 2021, the Company issued a convertible note payable in the ~~principal~~ amount of ~~$78,000. The note accrues interest at 12% per annum and~~$647,222 which matures on ~~January 10, 2021. Any amount of principal or interest which is not paid at maturity shall accrue interest at 22% per annum. The~~July 28, 2021 in exchange for another note also includes certain prepayment penalties that provide for payments ranging from 115% to 140% of the then-outstanding principal and interest. The note is convertible at the option of the holder into common stock at 61% of the lowest trading price during the ten (10) consecutive trading days prior to the conversion date at any time during the period which is 180 days following the issuance date of the convertible note and ending on the later of (i) January 10, 2021 or (ii), in the event of default, the date of the payment of the default amount.

Certain conditions may exist as of the date the condensed consolidated financial statements are issued, which may result in a loss to the Company, but which will only be resolved when one or more future events occur or fail to occur. The Company assesses such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company, or unasserted claims that may result in such proceedings, the Company evaluates the ~~perceived~~ merits of any legal proceedings or unasserted claims, as well as the ~~perceived~~ merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Company’s condensed consolidated financial statements. If the assessment indicates that a potential material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability and an estimate of the range of possible losses, if determinable and material, would be disclosed.

We are a cell therapy company focused on immunotherapy. Since our inception, we have been involved with the development of proprietary immune system management technology licensed from Yeda Research & Development Company Limited (“Yeda”), the commercial arm of the Weizmann ~~Institute of Science.~~Institute. We have recently shifted the focus of our ~~Research~~research and ~~Development~~development efforts to MD Anderson.

This technology addresses one of the most fundamental challenges within human immunology: how to tune the immune response such that it tolerates selected desirable foreign cells, ~~or tissue,~~ but continues to attack all other (undesirable) targets. In simpler terms, a number of potentially life-saving treatments have limited effectiveness today because the patient’s immune system rejects them. For example, while HSCT - hematopoietic stem cell transplantation (e.g. bone marrow transplantation) has become a preferred therapeutic approach for treating blood cell cancer, most patients do not have a matched family donor. Although matched unrelated donors and cord blood can each provide an option for such patients, haploidentical stem cell transplants (sourced from partially mismatched family members) are rapidly gaining favor as a treatment of choice. This is still a risky and difficult procedure primarily because of potential conflicts between host and donor immune systems and also due to viral infections that often follow even successful HSCT while the compromised new immune system works to reconstitute itself by using the transplanted stem cells. Today, rejection is partially overcome using aggressive immune suppression treatments that leave the patient exposed to many dangers by compromising their immune system.

The unique advantage of Cell Source technology lies in the ability to induce sustained tolerance of transplanted cells (or organs) by the recipient’s immune system in a setting that requires only mild immune suppression, while avoiding the most common post-transplant complications. The scientific term for inducing such tolerance in a transplantation setting is chimerism, where the recipient’s immune system tolerates the co-existence of the (genetically different) donor type and host (recipient) type cells. Attaining sustained chimerism is an important ~~prerequisite~~perquisite to achieving the intrinsic GvL (graft versus leukemia) effect of HSCT and supporting the reconstitution of normal hematopoiesis (generation of blood cells, including those that protect healthy patients from cancer) in blood cancer patients. Preclinical data and initial clinical data show that Cell Source’s Veto Cell technology ~~(currently in clinical trials in the US)~~ can provide superior results in allogeneic (donor-derived) HSCT by allowing for haploidentical stem cell transplants under a mild conditioning regimen, while avoiding the most common post-transplant complications. Combining this with CAR (Chimeric Antigen Receptor) T cell therapy as a unified VETO CAR-T treatment, we will be able to treat patients in relapse as well as those in remission and use the cancer killing power of CAR-T to protect the patient while their immune system fully reconstitutes, thus providing an end-to-end solution for blood cancer treatment by potentially delivering a fundamentally safer and more effective allogeneic HSCT: prevention of relapse; avoidance of GvHD; prevention of viral infections; and enhanced persistence of GvL effect. This means that the majority of patients will be able to find a donor, and will have access to a potentially safer procedure with higher long term survival rates than what either donor-derived HSCT or autologous CAR-T each on their own currently provide.

The ability to induce permanent chimerism (and thus sustained tolerance) in patients – which allows the transplantation to overcome rejection without having to compromise the rest of the immune system - may open the door to effective treatment of a number of severe medical conditions, in addition to blood cancers, which are characterized by this need. These include:

~~COVID-19~~Other than our Chief Executive Officer, we currently do not have any full-time employees, but retain the services of independent contractors/consultants on a contract-employment basis.

After two years of intensive collaboration with Professor Zelig Eshhar, the ~~outbreak~~inventor of CAR-T cell therapy, interim data confirmed that Veto Cells can markedly extend persistence of genetically modified T cells from the same donor and that genetically modified Veto Cells can effectively inhibit tumors expressing an antigen recognized by the transgenic T cell receptor. Furthermore, human Veto Cells transfected with CAR exhibit anti-tumor activity in-vitro without losing their veto activity. These preclinical results will form the basis of the development of a clinical protocol for allogeneic VETO CAR-T HSCT combined therapy for blood cancer treatment. Cell Source plans to submit this protocol for approval by the end of 2021. The Phase 1/2 clinical trial at the University of Texas MD Anderson Cancer Center, using Cell Source’s Anti-viral Veto Cells, has successfully completed the first treatment cohort, with 3 patients each receiving a haploidentical HSCT under reduced intensity conditioning with Veto Cells. This first in human dose optimization trial has thus far shown that the initial dose is in fact the optimal dose, as all three patients had successful stem cell engraftment after 42 days, in the absence of GvHD. Cell Source is now continuing the trial as it proceeds with the next cohort of patients, using the same dose level.

In March 2020, the World Health Organization declared COVID-19, a novel strain of coronavirus, a pandemic. During 2020 and continuing into 2021, the global economy has been, and continues to be, affected by COVID-19. While we continue to see signs of economic recovery as certain governments began to gradually ease restrictions, provide economic stimulus and vaccine distribution accelerated, the rate of recovery on a global basis has been affected by resurgence of the virus or its variants in certain jurisdictions causing reinstatement of restrictions in certain jurisdictions. We continue to monitor the effects of COVID-19 ~~around~~and its impact on our operations, financial position, cash flows and our industry in general.

The full extent of the outbreak has been rapidly evolving, and many countries have reacted by instituting quarantines and restrictions on travel, and many businesses and other institutions have temporarily closed or reduced work activities at their facilities. Such actions are creating disruption in global supply chains, and adversely impacting a number of industries, such as transportation, hospitality and entertainment. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown.

On June 18, 2020, the Company received proceeds of $500,000 through a previously issued convertible note dated October 28, 2019 in the principal amount of $1,500,000, such that the Company had now received aggregate proceeds of $1,500,000 under the convertible note. The convertible note has a maturity date of October 31, 2020. In connection with the receipt of these proceeds, the Company issued a five-year immediately vested warrant for the purchase of 1,200,000 shares of common stock at an exercise price of $1.25 per share.

On July 29, 2020, the Company issued a convertible note payable in the principal amount of $555,556 for net proceeds of $497,500 (gross proceeds of $500,000 less $2,500 of issuance costs) which matures on January 29, 2021. The note accrues interest at 13% per annum and is convertible into common stock at the lower of (i) a conversion price of $0.75 per share (the “Fixed Conversion Price”) or (ii) in the event of a default, as defined in the note, a conversion price of 65% of the lowest volume weighted average price for the ten consecutive trading days ending on the trading day that is immediately prior to the applicable conversion date (the “Default Conversion Price”). The Default Conversion Price shall not apply before March 29, 2021. So long as the convertible note is outstanding, upon any issuance by the Company of any equity at an effective price lower than the conversion price (the “Base Conversion Price”), then the conversion price shall be reduced to equal such Base Conversion Price. In connection to the issuance of the convertible note payable, the Company ~~issued a five-year immediately vested warrant to purchase 146,199 shares of common stock at an exercise price of $0.95 per share, which~~ ~~may be exercised on a cashless basis.~~

During the ~~six~~three months ended ~~June 30, 2020,~~March 31, 2021, we had not generated any revenues, had a net loss of approximately ~~$1,978,000~~$1,525,000 and had used cash in operations of approximately ~~$1,154,000.~~$1,114,000. As of ~~June 30, 2020,~~March 31, 2021, we had a working capital deficiency of approximately ~~$6,528,000~~$9,142,000 and an accumulated deficit of approximately ~~$23,124,000.~~$27,231,000. Subsequent to ~~June 30, 2020,~~March 31, 2021, we received proceeds of ~~$603,355 through the sale of 80,446 shares of Series A Convertible Preferred Stock at $7.50 per share and net proceeds of $497,500~~$100,000 through the issuance of a convertible ~~note payable in the principal amount of $555,556.~~notes payable. These conditions raise substantial doubt about our ability to continue as a going concern ~~within twelve months~~for at least one year from the date these financial statements are issued.

We are currently funding ~~its~~our operations on a month-to-month basis. Our ability to continue our operations is dependent on the execution of management’s plans, which include the raising of capital through the debt and/or equity markets, until such time that funds provided by operations are sufficient to fund working capital requirements. We may need to incur additional liabilities with certain related parties to sustain our existence. If we were not to continue as a going concern, we would likely not be able to realize our assets at values comparable to the carrying value or the fair value estimates reflected in the balances set out in the preparation of our financial statements.

There can be no assurances that we will be successful in generating additional cash from equity or debt financings or other sources to be used for operations. Should we not be successful in obtaining the necessary financing to fund our operations, we would need to curtail certain or all operational activities and/or contemplate the sale of our assets, if necessary.

During the ~~six~~three months ended ~~June 30,~~March 31, 2021 and 2020, ~~and 2019,~~ our sources and uses of cash were as follows:

We experienced negative cash flows from operating activities for the ~~six~~three months ended ~~June 30,~~March 31, 2021 and 2020 ~~and 2019~~ in the amounts of ~~approximately $1,154,000~~$1,114,281 and ~~$1,186,000,~~$618,386, respectively. The net cash used in operating activities for the ~~six~~three months ended ~~June 30, 2020~~March 31, 2021 was primarily due to cash used to fund a net loss of approximately ~~$1,978,000,~~$1,525,000, adjusted for net non-cash expenses in the aggregate amount of ~~approximately $516,000, partially offset by $308,000~~ $541,000, and $131,000 of net cash ~~provided by~~used in changes in the levels of operating assets and liabilities.

Net cash provided by financing activities for the ~~six~~three months ended ~~June 30,~~March 31, 2021 and 2020 was $972,250 and ~~2019 was approximately $1,127,000 and $1,195,000,~~$607,000, respectively. The net cash provided by financing activities during the ~~six~~three months ended ~~June 30, 2020~~March 31, 2021 was attributable to ~~$1,075,000~~$1,197,250 of proceeds from the issuance of convertible notes payable, ~~$125,000~~offset by the repayments of notes payable and convertible notes payable in the amount of $225,000.

~~For~~The preparation of financial statements and related disclosures in conformity with U.S. GAAP. These accounting principles require us to make estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenue and expense during the periods presented. We believe that the estimates and judgments upon which it relies are reasonably based upon information available to us at the time that it makes these estimates and judgments. To the extent that there are material differences between these estimates and actual results, our financial results will be affected. The accounting policies that reflect our more significant estimates and judgments and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results are described below.

The following is not intended to be a ~~description~~comprehensive list of all of our ~~critical~~ accounting policies ~~see~~or estimates. Our accounting policies are more fully described in Note 3 – Summary of Significant Accounting Policies, in ~~Part 1, Item 1 of~~our financial statements included elsewhere in this ~~Quarterly Report on Form 10-Q.~~quarterly report.

The Company evaluates its convertible instruments to determine if those contracts or embedded components of those contracts qualify as derivative financial instruments to be separately accounted for in accordance with Topic 815 of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). The accounting treatment of derivative financial instruments requires that the Company record embedded conversion options and any related freestanding instruments at their fair values as of the inception date of the agreement and at fair value as of each subsequent balance sheet date. Any change in fair value is recorded as non-operating, non-cash income or expense for each reporting period at each balance sheet date. The Company reassesses the classification of its derivative instruments at each balance sheet date. If the classification changes as a result of events during the period, the contract is reclassified as of the date of the event that caused the reclassification. Embedded conversion options and any related freestanding instruments are recorded as a discount to the host instrument.

If the instrument is determined to not be a derivative liability, the Company then evaluates for the existence of a beneficial conversion feature by comparing the commitment date fair value to the effective conversion price of the instrument.

The Black-Scholes option pricing model was used to estimate the fair value of the Company’s warrants and embedded conversion options. The Black-Scholes option pricing model includes subjective input assumptions that can materially affect the fair value estimates. The Company determined the fair value under the Binomial Lattice model and the Black-Scholes option pricing model to be materially the same.

Embedded conversion options within notes payable are recorded as a debt discount and are amortized as interest expense over the term of the related debt instrument.

The Company measures the fair value of financial assets and liabilities based on ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”), which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.

ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value:

Level 1 — quoted prices in active markets for identical assets or liabilities;

Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable; and

Level 3 — inputs that are unobservable (for example, cash flow modeling inputs based on assumptions).

The carrying amounts of the Company’s financial instruments, such as cash, other current assets, accounts payable, accrued expenses and other current liabilities approximate fair values due to the short-term nature of these instruments. The carrying amounts of Company’s credit obligations approximate fair value because the effective yields on these obligations, which include contractual interest rates, are comparable to rates of returns for instruments of similar credit risk.

The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. The fair value of the award is measured on the grant date and is then recognized over the period the services are required to be provided in exchange for the award, usually the vesting period. Awards granted to directors are treated on the same basis as awards granted to employees. Upon the exercise of an option or warrant, the Company issues new shares of common stock out of its authorized shares.

Because the Company’s common stock historically was not actively traded on a public market, the fair value of the Company’s restricted equity instruments is estimated by management based on observations of the sales prices of both restricted and freely tradable common stock, or instruments convertible into common stock. The Company obtained a third-party valuation of its common stock as of December 31, 2020, which was considered in management’s estimation of fair value during the three months ended March 31, 2021. The third-party valuation was performed in accordance with the guidance outlined in the American Institute of Certified Public Accountants’ Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The estimates used by management are considered highly complex and subjective. The Company anticipates that once its shares become more actively traded, the use of such estimates will no longer be necessary to determine the fair value of its common stock.

The December 2020 independent appraisal utilized the option pricing method, or OPM, as the most reliable method with the following steps being applied:

Under the OPM, it was determined the Company’s common stock a fair value of $0.47 per share, which included a discount for lack of marketability of 30%. Furthermore, the independent appraisal determined the Company’s expected volatility was 90% by evaluating historical and implied volatilities of guideline companies.

Disclosure controls are procedures that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this Annual Report, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the Principal Executive and Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Internal controls are procedures which are designed with the objective of providing reasonable assurance that (1) our transactions are properly authorized, recorded and reported; and (2) our assets are safeguarded against unauthorized or improper use, to permit the preparation of our condensed consolidated financial statements in conformity with United States generally accepted accounting principles.

In connection with the preparation of this Quarterly Report, management, with the participation of our Principal Executive and Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)). Based upon that evaluation, our Principal Executive and Financial Officer concluded that, as of ~~June 30, 2020,~~March 31, 2021, our disclosure controls and procedures were effective.

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended ~~June 30, 2020~~March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Except as described below, we are not involved in any pending legal proceeding or litigations and, to the best of our knowledge, no governmental authority is contemplating any proceeding to which we are a party or to which any of our properties is subject, which would reasonably be likely to have a material adverse effect on us.

In January 2019, the holder of a promissory note in the principal amount of $250,000 due on March 16, 2016 instituted a collection action in the Supreme Court of the State of New York, County of New York. A motion for summary judgement was heard on ~~March 7,~~July 12, 2019 and the ~~Company did not oppose the motion.~~Company’s motion to vacate was denied in February 2021.

The note accrues interest at 13% per annum and is convertible into common stock at the lower of (i) a conversion price of $0.75 per share (the “Fixed Conversion Price”) or (ii) in the event of a default, as defined in the note, a conversion price of 65% of the lowest volume weighted average price for the ten consecutive trading days ending on the trading day that is immediately prior to the applicable conversion date (the “Default Conversion Price”). The Default Conversion Price shall not apply before March 29, 2021. So long as the convertible note is outstanding, upon any issuance by our equity at an effective price lower than the conversion price (the “Base Conversion Price”), then the conversion price shall be reduced to equal such Base Conversion Price. In connection to the issuance of the convertible note payable, we issued a five-year immediately vested warrant to purchase 146,199 shares of common stock at an exercise price of $0.95 per share, which may be exercised on a cashless basis. We relied upon the exemption provided by Section 4(2) of the Securities Act in connection with this transaction.

As of ~~June 30, 2020~~March 31, 2021 and through the date of this filing, notes payable and convertible notes payable with face values totaling ~~$1,538,000~~$1,558,000 and $1,858,000 respectively, were past due and are classified as current liabilities on the condensed consolidated balance sheet as of ~~June 30, 2020.~~March 31, 2021. Such notes continue to accrue interest and all relevant penalties have been accrued as of ~~June 30, 2020.~~March 31, 2021. Of such past due notes payable, a holder of a note with principal amount of $250,000 issued a notice of default. See Item 1 above for additional details. We are in negotiations with all holders to extend the maturity dates of such notes or to convert the principal and accrued interest into equity.

Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
