In accordance with General Instruction I.B.6 of Form S-3, pursuant to this prospectus supplement and the accompanying prospectus,we may, but are not obligated to, offer and sell shares of our common stock having an aggregate offering price of up to $7,939,771from time to time through or to Maxim acting as our sales agent or principal.

Maxim is not required to sell any specific number or dollaramount of securities, but will act as our sales agent using commercially reasonable efforts consistent with its normal trading and salespractices to sell shares of common stock as requested to be sold by us, on mutually agreed terms between Maxim and us. There is noarrangement for funds to be received in any escrow, trust or similar arrangement. These types of offerings will allow us to raise capital by selling shares of our common stock in open market transactions at ourdiscretion. Unlike in underwritten public offerings, sales under at-the-market offerings are not marketed, are made at prevailing marketprices, and generally are less dilutive to stockholders. This is because these types of at-the-market offerings typically are lessexpensive to transact than marketed offerings and can be executed without a discount to the prevailing market price of the stock that istypical in marketed offerings. Our board of directors has concluded that, at this time, it is in our best interest to have this offeringprogram available so that it can be used at our discretion for capital raising and other purposes more fully described in the sectionentitled “Use of Proceeds” in this prospectus supplement.
