 that we will be able to sell any
shares under or fully utilize the Sales Agreement with the Sales Agent.

We currently intend to use the net proceeds from
the sale of the securities offered under this prospectus supplement for working capital and general corporate purposes. Although we may
use a portion of the net proceeds of this offering for the acquisition or licensing, as the case may be, of additional technologies,
other assets or businesses, to repay certain debt obligations, if triggered, or for other strategic investments or opportunities, we
have no current understandings, agreements or commitments to do so.

Our management will have broad discretion in the
application of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of this
offering. Our stockholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover,
our management may use the net proceeds for corporate purposes that may not positively impact our results of operations or increase the
market value of our Common Stock. Pending any use, as described above, we plan to deposit the net proceeds in money market or similar
interest-bearing accounts with our primary bank or otherwise invest the net proceeds in high-quality, short-term, interest-bearing securities.

DILUTION</div>

If you invest in our common stock, your ownership
interest will be diluted to the extent of the difference between the public offering price per share and the as adjusted net tangible
book value per share after this offering. The net tangible book value of our common stock on June 30, 2025, was approximately $(6.4)
million, or approximately $(1.89) per share of common stock. We calculate net tangible book value per share by dividing the net tangible
book value, which is tangible assets less total liabilities, by the number of outstanding shares of our common stock. Dilution with respect
to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock
in this offering and the as adjusted net tangible book value per share of our common stock immediately after this offering.

After giving effect to an assumed sale of 18,072,289
shares of our common stock pursuant to this prospectus supplement and the accompanying prospectus in the aggregate amount of approximately
$30 million at an assumed price of $1.66 per share, and after deducting commissions and estimated offering expenses payable by us (estimated
at $270,500),
