 and third-party warrants
are generally determined using the Black-Scholes option-pricing model using various inputs, including estimates of historic volatility,
term, risk-free rate, and future dividends. The grant date fair value of the stock-based awards, which have graded vesting, is recognized
using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the
respective stock-based awards. The Company recognizes forfeitures as they occur.

Income Taxes

Income taxes are accounted
for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates applied
to taxable income in the years in which those temporary differences are expected to be realized. The effect on deferred tax assets
and liabilities of a change in tax rates is recognized as income or loss in the period that includes the enactment date. A valuation allowance
is established when necessary to reduce deferred tax assets to the amount expected to be realized. Interest and penalties related to unrecognized
tax benefits are included within the provision of income tax. To date, there have been unrecognized tax benefits balances.

Fair Value

Fair value is defined 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. The Company’s valuation
techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company follows
a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that
may be used to measure fair value. These levels of inputs are the following:

| ● | Level 1 — Quoted prices in active markets for 
 identical assets or liabilities.              |

| ● | Level 2 — Inputs other than Level 1 that are observable,                                                                              
 either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; 
 or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or 
 liabilities.                                                                                                                          |

| ● | Level 3 — Unobservable inputs that are supported
