The Amended and Restated

2020 Plan initially provided for the issuance of up to 312,500 shares of common stock, which amount will be increased to the

extent that awards granted under the Plans are forfeited, expire or are settled for cash (except as otherwise provided in the Amended

and Restated 2020 Plan).

In addition, the Amended and Restated 2020 Plan contains an “evergreen provision” providing

for an annual increase in the number of shares of our common stock available for issuance under the Amended and Restated 2020 Plan

on January 1 of each year for a period of ten years, commencing on January 1, 2021 and ending on (and including) January 1, 2030,

and Restated 2020 Plan on December 31st of such preceding calendar year (including shares subject to outstanding awards, issued

pursuant to awards or available for future awards).

The Board of Directors determines the exercise price, vesting and expiration

period of the grants under the Amended and Restated 2020 Plan.

However, the exercise price of an incentive stock option may not

be less than 110% of fair value of the common stock at the date of the grant for a 10% or more shareholder and 100% of fair value

for a grantee who is not a 10% shareholder.

fair value of stock options on the date of grant, based on the Black Scholes option pricing model using certain assumptions discussed

below, and the closing market price of our common stock on the date of the grant.

For employees and directors, the fair value of

the award is measured on the grant date.

Most stock options granted pursuant to the Plans typically vest 1/3rd 12 months from the

date of grant and 1/36th each month thereafter for 24 months and expire ten years from the date of grant.

In addition, we issue

options to directors which vest over a one-year period.

We also issue premium options to executive officers, which have an exercise

price greater than the grant date fair value, subject to a one year minimum service period prior to vesting.

Stock-based compensation

expense related to awards is amortized over the applicable vesting period using the straight-line method.

The weighted average

fair value of options granted during the three and nine months ended September 2022 was $0 per share and $5.25 per share, respectively.

The weighted average fair value of options granted during the three and nine months ended September 2021 was $21.46 per share and

if actual results differ from our estimates.

We make estimates of our accrued expenses as of each balance sheet date based on the facts

and circumstances known to us at that time.

Our clinical trial accruals and prepaid assets are dependent upon the timely and accurate

reporting of contract research organizations and other third-party vendors.

Compensation.

All stock-based payments to employees and to nonemployee directors for their services as directors consisted of grants of

restricted stock and stock options, which are measured at fair value on the grant date and recognized in the consolidated statements of

operations as compensation expense over the relevant vesting period.

In addition, for awards that vest immediately and are nonforfeitable,

DISCLOSURES ABOUT MARKET RISK

Not required under

Regulation S-K for “smaller reporting companies.”

Adopted Accounting Pronouncements

August 2020, the FASB issued ASU No.

2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives

and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40):

Accounting for Convertible Instruments and Contracts in an

Entity’s Own Equity , which simplifies accounting for convertible instruments by removing major separation models required under

current GAAP.

The ASU also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative

scope exception, and it also simplifies the diluted earnings per share calculation in certain areas.

We adopted ASU 2020-06 on January

1, 2023, under the modified retrospective method of transition.

The adoption of ASU 2020-06 did not impact the Company’s financial

position, results of operations or cash flows.
