business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations

and the trading price of our securities.

The following information updates, and should be read in conjunction with, the information

disclosed in Part I, Item 1A, “Risk Factors,” contained in the Annual Report.

Except as described below,

our risk factors as of the date of this Report have not changed materially from those described in “Part I, Item 1A.

Risk Factors” of our Annual Report.

Certain shares previously

sold under our ATM Sales Agreement may have been sold in violation of federal and state securities laws and may be subject to rescission

rights and other penalties, requiring us to repurchase shares sold thereunder.

In connection with our At-the-Market-Sales

Agreement, dated March 10, 2021 (the “Sales Agreement”), we recently became aware that our shelf registration statement on

Form S-3 (file number 333-237368) (the “Registration Statement”) expired on April 2, 2023.

Prior to becoming aware of

the expiration, we sold an aggregate of 75,697 shares of our common stock following the expiration of the Registration Statement and through

July 17, 2023 at an average price of approximately $10.56 per share for an aggregate of approximately $799,212 under the Registration

Statement pursuant to the Sales Agreement (the “Sales”).

Because the Registration Statement had already expired, the Sales

could be determined to be unregistered sales of securities and, in accordance with Section 5 of the Securities Act, direct purchasers

in the Sales may have rescission rights pursuant to which they may be entitled to recover the amount paid for such shares, plus statutory

interest, upon returning the shares to us within one year from the transaction date.

In addition, we could be subject to enforcement actions

or penalties and fines by federal and/or state regulatory authorities.

We cannot predict the likelihood of any claims or actions being

brought against us or the amount of any penalties or fines in connection with the Sales.
