 prospective investors. The Placement Agency Agreement does not give rise to any commitment by the Placement
Agent to purchase any of our Shares of Common Stock and Warrants, and the Placement Agent will have no authority to bind us by virtue
of the Placement Agency Agreement. Further, the Placement Agent does not guarantee that it will be able to raise new capital in any prospective
offering. The Placement Agent may engage sub-agents or selected dealers to assist with the Offering.

We will enter into a securities
purchase agreement directly with investors in connection with this Offering, and we will only sell to investors who have entered into
securities purchase agreements.

We expect to deliver the shares
of our Common Stock and Warrants being offered pursuant to this prospectus supplement on or about May 16, 2025, subject to the satisfaction
of customary closing conditions.

We will pay the Placement Agent
a cash transaction fee in an amount equal to 7.0% of the aggregate gross proceeds to us in connection with the closing of the Offering.

The following table shows the
per Share and accompanying Warrants and total Placement Agent fees we will pay in connection with the sale of the Securities in this Offering,
assuming the purchase of all of the Securities we are offering and assuming no exercise of the Warrants.

| Placement Agent fees             |     | $             | 0.1099 |     | $     |    770,000.06 |
| Proceeds, before expenses, to us |     | $             | 1.4601 |     | $     | 10,230,000.84 |

We estimate the total expenses of this Offering, which will be payable
by us, excluding the Placement Agent fees, will be approximately $150,000. After deducting the fees due to the Placement Agent and our
estimated offering expenses, we expect the net proceeds from this Offering to be approximately $10 million.

the Placement Agent and specified other persons against some civil liabilities, including liabilities under the Securities Act, and the
Securities Exchange Act of 1934, as amended
