On November 22, 2022, we entered into the SEPA with YA II PN, Ltd. ("Yorkville"), pursuant to which Yorkville has committed to purchase up to $10,000,000 of our common stock, subject to certain limitations and conditions set forth in the SEPA. We have the right to control the timing and amount of any sales of our shares of common stock to Yorkville under the SEPA. As of December 31, 2023, we sold a total of 1,576,545 shares of common stock and the company received $1.9 million in net proceeds from the sales.
Although the SEPA provides that we may sell up to an aggregate of $10,000,000 of our common stock to Yorkville, only 4,035,086 shares of our common stock, including the aggregate amount of 61,421 Commitment Shares issued to Yorkville, have been registered. If we elect to sell to the Yorkville all of the 4,035,086 registered shares of common stock, depending on the market price of our common stock prior to each Advance made pursuant to the SEPA, the actual gross proceeds from the sale of all such shares may be substantially less than the $10,000,000 available to us, which could materially adversely affect our liquidity.
If it becomes necessary for us to issue and sell to Yorkville under the SEPA more than the 4,035,086 shares registered for resale in order to receive aggregate gross proceeds equal to $10,000,000, we must file with the SEC one or more additional registration statements to register under the Securities Act the resale by Yorkville of any such additional shares of our common stock we wish to sell from time to time under the SEPA, which the SEC must declare effective. Additionally, we would need to obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap under the SEPA in accordance with applicable Nasdaq rules, unless all applicable sales of shares of common stock under the SEPA equal or exceed the "Minimum Price" (as such term is defined in the Nasdaq Rules) or, as to any Advance, the issuance of the common stock pursuant to an Advance Notice would be excluded from the Exchange Cap under Nasdaq rules (or interpretive guidance provided by the Nasdaq with respect thereto), in which case, under applicable Nasdaq rules, the Exchange Cap limitation would not apply to issuances and sales of common stock under the SEPA. Any issuance and sale by us under the SEPA of shares of common stock in addition to the 4,035,086 shares of common stock registered for resale by Yorkville could cause additional dilution to our stockholders.
We are not required or permitted to issue any shares of common stock under the SEPA if such issuance would breach our obligations under the rules or regulations of the Nasdaq Stock Market LLC. In addition, Yorkville will not be required to purchase any shares of our common stock if such sale would result in their beneficial ownership exceeding 9.99% of the then issued and outstanding common stock. Our inability to access a part or all of the amount available under the SEPA, in the absence of any other financing sources, could have a material adverse effect on our business.
If we elect to draw down amounts under the SEPA, which will result in the sale of shares of our common stock to Yorkville, any such draw-downs may have a dilutive impact on our existing shareholders. Though we have been advised by Yorkville, and Yorkville represents in the SEPA, that Yorkville is purchasing the shares for its own account, for investment purposes, and without any view or intention to distribute such shares in violation of the Securities Act or any other applicable securities laws, Yorkville may resell some or all of the shares we issue to it pursuant to draw-downs under the SEPA and such sales could cause the market price of our common stock to decline.
