 on August 25, 2025, registering the resale of up to 8,970,830 shares by Ascent pursuant
to the Purchase Agreement. In addition, we have filed the registration statement that includes this prospectus with the SEC to register
under the Securities Act the resale by Ascent of up to an additional 42,211,548 Purchase Shares that we may, in our sole discretion, elect
to sell to Ascent, from time to time over a period of up to 36 months from and after the Effective Date (defined below) pursuant
to the Purchase Agreement.

Under the Purchase Agreement,
we have the right, but not the obligation, from time to time at our sole discretion for a period of up to 36 months, unless the Purchase
Agreement is earlier terminated, to direct Ascent to purchase up to a specified maximum amount of shares of Common Stock in one or more
Purchases as set forth in the Purchase Agreement, by delivering a written Advance Notice, if any, to Ascent in accordance with the Purchase
Agreement on any trading day we select.

From and after Commencement,
the Company will control the timing and amount of any sales of Common Stock to Ascent. Actual sales of shares of our Common Stock to Ascent
under the Purchase Agreement will depend on a variety of factors to be determined by us from time to time, including, among other things,
market conditions, the trading price of our Common Stock and determinations by us as to the appropriate sources of funding for our Company
and its operations.

Moreover, we may not issue
or sell any shares of Common Stock to Ascent under the Purchase Agreement which, when aggregated with all other shares of Common Stock
then beneficially owned by Ascent and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 thereunder),
would result in Ascent beneficially owning shares of Common Stock in excess of the 9.99% Beneficial Ownership Limitation.

The net proceeds to us from
sales that we elect to make to Ascent under the Purchase Agreement, if any, will depend on the frequency and prices at which we sell shares
of our Common Stock to Ascent. We expect that any proceeds received by us from such sales to Ascent will be used for working capital and
general corporate purposes.

Neither we nor Ascent may assign
or transfer our respective rights and obligations under the Purchase Agreement or the ELOC Registration Rights Agreement, and no
