Note 5. Short-Term Notes Payable

On March 13, 2025, we issued a $3.0 million promissory note (the “Note”) to a single investor at an original issue discount of 17%. Net proceeds to us were approximately $2.2 million after placement agent fees of $175,000 and legal expenses of $98,437.

No interest accrues on the Note unless an event of default occurs, at which time interest will accrue at a rate of 20% per annum. The Note matures upon the earlier of July 14, 2025, or the closing of any subsequent offering by us with net proceeds equal to or in excess of all amounts due under the Note.

In connection with the issuance of the Note, we designated and issued 1,000,000 shares of our authorized but unissued Series G Mirroring Preferred Stock. For a description of the Series G terms, see Note 8. We used the net proceeds for working capital and general corporate purposes. Subsequently, in connection with the Reverse Stock Split the shares of Series G Preferred Stock were cancelled. See Note 8.
