Biopharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, &#x201c;Provectus&#x201d; or the &#x201c;Company&#x201d;),
is a clinical-stage biotechnology company developing immunotherapy medicines for different diseases, with the aim of maximizing the curative
impact of these medicines and achieving immunity from treated disease. These investigational drugs are based on a wholly owned class
of small molecules called halogenated xanthenes (&#x201c;HXs&#x201d;). Our lead HX molecule is named rose bengal sodium (&#x201c;RBS&#x201d;).&lt;/span&gt;&lt;/p&gt;

was reportedly first identified in late-2019 and subsequently declared a global pandemic by the World Health Organization on March 11,
2020. As a result of the SARS-CoV-2 pandemic, many companies have experienced disruptions of their operations and the markets they serve.
The Company has taken several temporary precautionary measures intended to help ensure the well-being of its employees and contractors
and to minimize business disruption. The Company considered the impact of SARS-CoV-2 pandemic on its business and operational assumptions
and estimates, and determined there were no material adverse impacts on the Company&#x2019;s results of operations and financial position
at December 31, 2021.&lt;/span&gt;&lt;/p&gt;

full extent of the SARS-CoV-2 pandemic impacts on the Company&#x2019;s operations and financial condition is still uncertain. The
Company has experienced slower than normal enrollment and treatment of patients, and a prolonged SARS-CoV-2 pandemic could have a material
adverse impact on the Company&#x2019;s business and financial results, including the timing and ability of the Company to raise capital,
initiate and/or complete current and/or future preclinical studies and/or clinical trials; disrupt the Company&#x2019;s regulatory activities;

The improvement in working capital is primarily driven by the conversion of the 2017 and 2020 Notes into Series D and D-1 Preferred Stock.
The Company continues to incur significant operating losses. Management expects that significant on-going operating expenditures will
be necessary to successfully implement the Company&#x2019;s business plan and develop and market its products. These circumstances raise
substantial doubt about the Company&#x2019;s ability to continue as a going concern within one year after the date that these consolidated
financial statements are issued. Implementation of the Company&#x2019;s plans and its ability to continue as a going concern will depend
upon the Company&#x2019;s ability to develop PV-10, PH-10, and/or any other halogenated xanthene-based drug products, and to raise additional
capital.&lt;/span&gt;&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company plans to access capital resources through possible public or private equity offerings, including the 2021 Financing (as defined
in Note 5), exchange offers, debt financings, corporate collaborations, or other means. In addition, the Company continues to explore
opportunities to strategically monetize its lead drug candidates, PV-10 and PH-10, through potential co-development and licensing transactions,
although there can be no assurance that the Company will be successful with such plans. The Company has historically been able to raise
capital through equity and debt offerings, although no assurance can be provided that it will continue to be successful in the future.

primary business objective of management is to build the Company into a commercial-stage biotechnology company; however, the Company
cannot assure that it will be successful in co-developing, licensing, and/or commercializing PV-10, PH-10, and/or any other halogenated
xanthene-based drug candidate developed by the Company or entering into any financial transaction. Moreover, even if the Company is successful
in improving its current cash flow position, the Company nonetheless plans to seek additional funds to meet its long-term requirements
in 2022 and beyond. The Company anticipates that these funds will otherwise come from the proceeds of private placement transactions,
the exercise of existing warrants and outstanding stock options, or public offerings of debt or equity securities. While the Company
believes that it has a reasonable basis for its expectation that it will be able to raise additional funds, the Company cannot provide
assurance that it will be able to complete additional financing in a timely manner. In addition, any such financing may result in significant
dilution to stockholders.&lt;/span&gt;&lt;/p&gt;

is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard,
disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty
of cash flows arising from leases. The Company is also required to recognize and measure new leases at the adoption date and recognize
a cumulative-effect adjustment in the period of adoption using a modified retrospective approach, with certain practical expedients available.&lt;/span&gt;&lt;/p&gt;

Company adopted ASC 842 effective January 1, 2019 and elected to apply the available practical expedients. The standard had an impact
on the Company&#x2019;s consolidated balance sheets but did not have a material impact on the Company&#x2019;s consolidated statements
of operations or cash flows upon adoption. The most significant impact was the recognition of ROU assets and lease liabilities for operating
leases.&lt;/span&gt;&lt;/p&gt;

Company accounts for income taxes under the liability method in accordance with Accounting Standards Codification (&#x201c;ASC&#x201d;)
740 &#x201c;Income Taxes&#x201d;. Under this method, deferred income tax assets and liabilities are determined based on differences between
financial reporting and tax basis 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. A valuation allowance is established if it is more likely than not that all, or some portion,
of deferred income tax assets will not be realized. The Company has recorded a full valuation allowance to reduce its net deferred income
tax assets to zero. In the event the Company were to determine that it would be able to realize some or all its deferred income tax assets
in the future, an adjustment to the deferred income tax asset would increase income in the period such determination was made.&lt;/span&gt;&lt;/p&gt;

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 ASC Topic 815: &lt;i&gt;Derivatives and Hedging&lt;/i&gt;. The accounting
treatment of derivative financial instruments requires that the Company record qualifying 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 classified as derivative liabilities and any related equity classified freestanding instruments are recorded
as a discount to the host instrument.&lt;/span&gt;&lt;/p&gt;

fair value. Conditionally redeemable preferred shares (including preferred shares that feature redemption rights that are either within
the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company&#x2019;s control)
are classified as temporary equity. At all other times, preferred shares are classified as stockholders&#x2019; deficiency.&lt;/span&gt;&lt;/p&gt;

loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the

stock were exercised or converted into common stock. The following securities are excluded from the calculation of weighted average dilutive
common shares because their inclusion would have been anti-dilutive:&lt;/span&gt;&lt;/p&gt;

Company measures the fair value of financial assets and liabilities based on the guidance of ASC 820 &#x201c;Fair Value Measurements and
Disclosures&#x201d; (&#x201c;ASC 820&#x201d;) which defines fair value, establishes a framework for measuring fair value, and expands disclosures
about fair value measurements. The Company determines the estimated fair value of amounts presented in these consolidated financial statements
using available market information and appropriate methodologies. However, considerable judgment is required in interpreting market data
to develop the estimates of fair value. The estimates presented in the financial statements are not necessarily indicative of the amounts
that could be realized in a current exchange between buyer and seller. The use of different market assumptions and/or estimation methodologies
may have a material effect on the estimated fair value amounts. These fair value estimates were based upon pertinent information available
as of December 31, 2021 and 2020. The carrying amounts of the Company&#x2019;s financial assets and liabilities, such as cash and cash
equivalents, restricted cash, receivables, other current assets, accounts payable, unearned grant income, and accrued expenses approximate
fair values due to the short-term nature of these instruments.&lt;/span&gt;&lt;/p&gt;

carrying amounts of our 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.&lt;/span&gt;&lt;/p&gt;

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:&lt;/span&gt;&lt;/p&gt;

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.&lt;/span&gt;&lt;/p&gt;

component of accumulated other comprehensive loss (&#x201c;AOCL&#x201d;), which is a separate component of stockholders&#x2019; deficiency.
Therefore, the U.S. dollar value of the non-equity translated items in the Company&#x2019;s consolidated financial statements will

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 then is recognized over the period during which services are required to be
provided in exchange for the award, usually the vesting period. The Company computes the fair value of equity-classified warrants and
options granted using the Black-Scholes option pricing model. Option valuation models require the input of highly subjective assumptions
including the expected volatility factor of the market price of the Company&#x2019;s common stock which is determined by reviewing its
historical public market closing prices.&lt;/span&gt;&lt;/p&gt;

August 2020, FASB issued Accounting Standards Update (&#x201c;ASU&#x201d;) No. 2020-06, &lt;i&gt;&#x201c;Debt&#x2014;Debt with Conversion
and Other Options (Subtopic 470-20) and Derivatives and Hedging&#x2014;Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40): Accounting
for Convertible Instruments and Contracts in an Entity&#x2019;s Own Equity&#x201d;&lt;/i&gt; (&#x201c;ASU 2020-06&#x201d;). Under ASU 2020-06,
the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features
that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for
as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized
cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted
method to be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including
interim periods within those fiscal years, with early adoption permitted. Adoption of the standard requires using either a modified retrospective
or a full retrospective approach. The Company is currently evaluating the effect of the adoption of ASU 2020-06 will have on its consolidated
financial statements and related disclosures.&lt;/span&gt;&lt;/p&gt;

October 2020, the FASB issued ASU 2020-10 &lt;i&gt;&#x201c;Codification Improvements&#x201d;&lt;/i&gt;, which improves consistency by amending the
Codification to include all disclosure guidance in the appropriate disclosure sections and clarifies application of various provisions
in the Codification by amending and adding new headings, cross referencing to other guidance, and refining or correcting terminology.
The guidance is effective for the Company beginning in the first quarter of fiscal year 2022 with early adoption permitted. The Company
adopted this standard on January 1, 2022 and it did not have a material effect on its consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

Compensation (Topic 718), and Derivatives and Hedging&#x2014;Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40): Issuer&#x2019;s
Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options.&lt;/i&gt; This new standard provides
clarification and reduces diversity in an issuer&#x2019;s accounting for modifications or exchanges of freestanding equity-classified
written call options (such as warrants) that remain equity classified after modification or exchange. This standard is effective for
fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard
prospectively to modifications or exchanges occurring after the effective date of the new standard. Early adoption is permitted, including
adoption in an interim period. If an issuer elects to early adopt the new standard in an interim period, the guidance should be applied
as of the beginning of the fiscal year that includes that interim period. The Company adopted this standard on January 1, 2022 and
it did not have a material effect on its consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

December 2019, the FASB issued ASU 2019-12,
&lt;i&gt;Simplifying the Accounting for Income Taxes.&lt;/i&gt; The amendments in ASU 2019-12 simplify the accounting for income taxes by removing
certain exceptions to the general principles in Accounting Standards Codification (&#x201c;ASC&#x201d;) Topic 740, &lt;i&gt;Income Taxes&lt;/i&gt;.
The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing

January 2020, the FASB issued ASU 2020-01, &lt;i&gt;&#x201c;Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures
(Topic 323), and Derivatives and Hedging (Topic 815).&#x201d;&lt;/i&gt; ASU 2020-01 states any equity security transitioning from the alternative
method of accounting under Topic 321 to the equity method, or vice versa, due to an observable transaction will be remeasured immediately
before the transition. In addition, the ASU clarifies the accounting for certain non-derivative forward contracts or purchased call options
to acquire equity securities stating such instruments will be measured using the fair value principles of Topic 321 before settlement
or exercise. 20 The Company adopted ASU 2020-01 on a prospective basis on January 1, 2021 and there was no material impact on the Company&#x2019;s

March 2020, the FASB issued ASU No.

addressed in this update. Issues 1 &#x2013; 5 were clarifications and codifications of previous updates. Issue 3 relates only to depository
and lending institutions and therefore would not be applicable to the Company. Issue 6 was a clarification on determining the contractual
term of a net investment in a lease for purposes of measuring expected credit losses, an issue not applicable to the Company. Issue 7
relates to the regaining control of financial assets sold and the recordation of an allowance for credit losses. The amendment related
to issues 1, 2, 4 and 5 became effective immediately upon adoption of the update. Issue 3 becomes effective for fiscal years beginning
after December 15, 2019. Issues 6 and 7 become effective on varying dates that relate to the dates of adoption of other updates. The
Company adopted the applicable provisions within ASU 2020-03 which became effective during fiscal 2020 and 2021 and this adoption did
not have a material impact on the Company&#x2019;s consolidated financial statements and financial statement disclosures.&lt;/span&gt;&lt;/p&gt;

of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during
the reporting period. The Company&#x2019;s significant estimates and assumptions include the recoverability
and useful lives of long-lived assets, stock-based compensation, accrued liabilities and the valuation allowance related to the Company&#x2019;s
deferred tax assets.&lt;/span&gt;&lt;/p&gt;

February 2016, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued a new standard related to leases to increase transparency
and comparability among organizations by requiring the recognition of operating lease right-of-use (&#x201c;ROU&#x201d;) assets and lease
liabilities on the balance sheet (&#x201c;ASC 842&#x201d;) with amendments issued in 2018. Most prominent among the changes in the standard
is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard,
disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty
of cash flows arising from leases. The Company is also required to recognize and measure new leases at the adoption date and recognize
a cumulative-effect adjustment in the period of adoption using a modified retrospective approach, with certain practical expedients available.&lt;/span&gt;&lt;/p&gt;

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

Company adopted ASC 842 effective January 1, 2019 and elected to apply the available practical expedients. The standard had an impact
on the Company&#x2019;s consolidated balance sheets but did not have a material impact on the Company&#x2019;s consolidated statements
of operations or cash flows upon adoption. The most significant impact was the recognition of ROU assets and lease liabilities for operating
leases.&lt;/span&gt;&lt;/p&gt;

740 &#x201c;Income Taxes&#x201d;. Under this method, deferred income tax assets and liabilities are determined based on differences between
financial reporting and tax basis 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. A valuation allowance is established if it is more likely than not that all, or some portion,
of deferred income tax assets will not be realized. The Company has recorded a full valuation allowance to reduce its net deferred income
tax assets to zero. In the event the Company were to determine that it would be able to realize some or all its deferred income tax assets
in the future, an adjustment to the deferred income tax asset would increase income in the period such determination was made.&lt;/span&gt;&lt;/p&gt;

Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained upon an examination.
Any recognized income tax positions would be measured at the largest amount that is greater than &lt;span id="xdx_901_ecustom--MinimumPercentageRequiredToRecognizedUncertainIncomeTaxPosition_pid_dp_uPure_c20210101__20211231_zbYLMvZxnSTh" title="Recognized income tax positions measured"&gt;50&lt;/span&gt;% likely of being realized. Changes
in recognition or measurement would be reflected in the period in which the change in judgment occurs. The Company would recognize any
corresponding interest and penalties associated with its income tax positions in income tax expense. There were no income taxes, interest
or penalties incurred in 2021 or 2020.&lt;/span&gt;&lt;/p&gt;

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 ASC Topic 815: &lt;i&gt;Derivatives and Hedging&lt;/i&gt;. The accounting
treatment of derivative financial instruments requires that the Company record qualifying 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 classified as derivative liabilities and any related equity classified freestanding instruments are recorded
as a discount to the host instrument.&lt;/span&gt;&lt;/p&gt;

Company applies the accounting standards for distinguishing liabilities from equity when determining the classification and measurement
of its preferred stock. Preferred shares subject to mandatory redemption are classified as liability instruments and are measured at
fair value. Conditionally redeemable preferred shares (including preferred shares that feature redemption rights that are either within
the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company&#x2019;s control)
are classified as temporary equity. At all other times, preferred shares are classified as stockholders&#x2019; deficiency.&lt;/span&gt;&lt;/p&gt;

loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the
period. Diluted earnings per share reflects the potential dilution that could occur if securities or other instruments to issue common
stock were exercised or converted into common stock. The following securities are excluded from the calculation of weighted average dilutive
common shares because their inclusion would have been anti-dilutive:&lt;/span&gt;&lt;/p&gt;

Company measures the fair value of financial assets and liabilities based on the guidance of ASC 820 &#x201c;Fair Value Measurements and
Disclosures&#x201d; (&#x201c;ASC 820&#x201d;) which defines fair value, establishes a framework for measuring fair value, and expands disclosures
about fair value measurements. The Company determines the estimated fair value of amounts presented in these consolidated financial statements
using available market information and appropriate methodologies. However, considerable judgment is required in interpreting market data
to develop the estimates of fair value. The estimates presented in the financial statements are not necessarily indicative of the amounts
that could be realized in a current exchange between buyer and seller. The use of different market assumptions and/or estimation methodologies
may have a material effect on the estimated fair value amounts. These fair value estimates were based upon pertinent information available
as of December 31, 2021 and 2020. The carrying amounts of the Company&#x2019;s financial assets and liabilities, such as cash and cash
equivalents, restricted cash, receivables, other current assets, accounts payable, unearned grant income, and accrued expenses approximate
fair values due to the short-term nature of these instruments.&lt;/span&gt;&lt;/p&gt;

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

carrying amounts of our 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.&lt;/span&gt;&lt;/p&gt;

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

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:&lt;/span&gt;&lt;/p&gt;

instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements
in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company&#x2019;s assessment

or liability.&lt;/span&gt;&lt;/p&gt;

observable and unobservable inputs may be used to determine the fair value of positions that are classified within the Level 3 category.
As a result, the unrealized gains and losses for assets within the Level 3 category may include changes in fair value that were attributable
to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in historical company data) inputs. 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.&lt;/span&gt;&lt;/p&gt;

component of accumulated other comprehensive loss (&#x201c;AOCL&#x201d;), which is a separate component of stockholders&#x2019; deficiency.
Therefore, the U.S. dollar value of the non-equity translated items in the Company&#x2019;s consolidated financial statements will
fluctuate from period to period, depending on the changing value of the U.S. dollar versus these currencies.&lt;/span&gt;&lt;/p&gt;

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 then is recognized over the period during which services are required to be
provided in exchange for the award, usually the vesting period. The Company computes the fair value of equity-classified warrants and
options granted using the Black-Scholes option pricing model. Option valuation models require the input of highly subjective assumptions
including the expected volatility factor of the market price of the Company&#x2019;s common stock which is determined by reviewing its
historical public market closing prices.&lt;/span&gt;&lt;/p&gt;

and Other Options (Subtopic 470-20) and Derivatives and Hedging&#x2014;Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40): Accounting
for Convertible Instruments and Contracts in an Entity&#x2019;s Own Equity&#x201d;&lt;/i&gt; (&#x201c;ASU 2020-06&#x201d;). Under ASU 2020-06,
the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features
that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for
as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized
cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted
method to be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including
interim periods within those fiscal years, with early adoption permitted. Adoption of the standard requires using either a modified retrospective
or a full retrospective approach. The Company is currently evaluating the effect of the adoption of ASU 2020-06 will have on its consolidated
financial statements and related disclosures.&lt;/span&gt;&lt;/p&gt;

October 2020, the FASB issued ASU 2020-10 &lt;i&gt;&#x201c;Codification Improvements&#x201d;&lt;/i&gt;, which improves consistency by amending the
Codification to include all disclosure guidance in the appropriate disclosure sections and clarifies application of various provisions
in the Codification by amending and adding new headings, cross referencing to other guidance, and refining or correcting terminology.
The guidance is effective for the Company beginning in the first quarter of fiscal year 2022 with early adoption permitted. The Company
adopted this standard on January 1, 2022 and it did not have a material effect on its consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

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

May 3, 2021, the FASB issued ASU
2021-04, &lt;i&gt;Earnings Per Share (Topic 260), Debt&#x2014;Modifications and Extinguishments (Subtopic 470-50), Compensation&#x2014;Stock
Compensation (Topic 718), and Derivatives and Hedging&#x2014;Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40): Issuer&#x2019;s
Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options.&lt;/i&gt; This new standard provides
clarification and reduces diversity in an issuer&#x2019;s accounting for modifications or exchanges of freestanding equity-classified
written call options (such as warrants) that remain equity classified after modification or exchange. This standard is effective for
fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard
prospectively to modifications or exchanges occurring after the effective date of the new standard. Early adoption is permitted, including
adoption in an interim period. If an issuer elects to early adopt the new standard in an interim period, the guidance should be applied
as of the beginning of the fiscal year that includes that interim period. The Company adopted this standard on January 1, 2022 and
it did not have a material effect on its consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

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

December 2019, the FASB issued ASU 2019-12,
&lt;i&gt;Simplifying the Accounting for Income Taxes.&lt;/i&gt; The amendments in ASU 2019-12 simplify the accounting for income taxes by removing
certain exceptions to the general principles in Accounting Standards Codification (&#x201c;ASC&#x201d;) Topic 740, &lt;i&gt;Income Taxes&lt;/i&gt;.
The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing
guidance. The Company adopted ASU 2019-12 on January 1, 2021 and there was no material impact on the Company&#x2019;s consolidated
financial statements or disclosures.&lt;/span&gt;&lt;/p&gt;

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

January 2020, the FASB issued ASU 2020-01, &lt;i&gt;&#x201c;Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures
(Topic 323), and Derivatives and Hedging (Topic 815).&#x201d;&lt;/i&gt; ASU 2020-01 states any equity security transitioning from the alternative
method of accounting under Topic 321 to the equity method, or vice versa, due to an observable transaction will be remeasured immediately
before the transition. In addition, the ASU clarifies the accounting for certain non-derivative forward contracts or purchased call options
to acquire equity securities stating such instruments will be measured using the fair value principles of Topic 321 before settlement
or exercise. 20 The Company adopted ASU 2020-01 on a prospective basis on January 1, 2021 and there was no material impact on the Company&#x2019;s
consolidated financial statements or disclosures.&lt;/span&gt;&lt;/p&gt;

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

March 2020, the FASB issued ASU No.
2020-03, &lt;i&gt;&#x201c;Codification Improvements to Financial Instruments&#x201d;&lt;/i&gt; (&#x201c;ASU 2020-03&#x201d;). There are seven issues
addressed in this update. Issues 1 &#x2013; 5 were clarifications and codifications of previous updates. Issue 3 relates only to depository
and lending institutions and therefore would not be applicable to the Company. Issue 6 was a clarification on determining the contractual
term of a net investment in a lease for purposes of measuring expected credit losses, an issue not applicable to the Company. Issue 7
relates to the regaining control of financial assets sold and the recordation of an allowance for credit losses. The amendment related
to issues 1, 2, 4 and 5 became effective immediately upon adoption of the update. Issue 3 becomes effective for fiscal years beginning
after December 15, 2019. Issues 6 and 7 become effective on varying dates that relate to the dates of adoption of other updates. The
Company adopted the applicable provisions within ASU 2020-03 which became effective during fiscal 2020 and 2021 and this adoption did
not have a material impact on the Company&#x2019;s consolidated financial statements and financial statement disclosures.&lt;/span&gt;&lt;/p&gt;

of a firm commitment had not been met since the Notes were not yet convertible. On June 17, 2021, the required Certificates of Designation
were filed with the Delaware Secretary of State. Accordingly, a firm commitment was achieved. The Company analyzed the Notes for a beneficial
conversion feature and determined that there was none because the Notes have an effective conversion price of $&lt;span id="xdx_904_eus-gaap--DebtInstrumentConvertibleConversionPrice1_iI_c20211231__us-gaap--AwardTypeAxis__custom--FirmCommitmentMember__srt--RangeAxis__srt--MinimumMember_zzsd6UTGvqm2" title="Effective conversion price"&gt;0.2862&lt;/span&gt; per share of underlying

the economic terms of the 2017 Notes substantially equivalent, on February 26, 2019, the Company entered into amendments (the

to change the conversion ratio by providing that one share of Preferred Stock would be convertible into 10 shares of common stock (the
&#x201c;New Conversion Ratio&#x201d;). The impact of the Amendments was to reduce by 10 times the number of shares of preferred stock into
which the 2017 Notes would convert, while keeping the economic terms the same. The 2020 Notes had substantially similar terms to the
Amended 2017 Notes, including being convertible into preferred stock at the New Conversion Price, with the Preferred Stock being convertible
into Common Stock at the New Conversion Ratio.&lt;/span&gt;&lt;/p&gt;

valuation allowance against deferred tax assets is required if, based on the weight of available evidence, it is more likely than not
that some or all of the deferred tax assets may not be realized. The Company is in the early stages of development and realization of
the deferred tax assets is not considered more likely than not. As a result, the Company has recorded a full valuation allowance for
the net deferred tax asset.&lt;/span&gt;&lt;/p&gt;
