Related Party Notes On October 9, 2023, we entered into note subscription agreements with each of John N. Hatsopoulos and Earl R. Lewis, III, each a director and shareholder of the Company, pursuant to which Mr. Hatsopoulos agreed to provide financing to us of up to $1,000,000, and Mr. Lewis agreed to provide financing to us of $500,000, and potentially, an additional $500,000 at his discretion. On October 10, 2023, we borrowed $500,000 from Mr. Hatsopoulos and issued him a one-year promissory note with interest accruing at 5.12% per annum. On July 23, 2024, we borrowed an additional $500,000 from Mr. Hatsopoulos, and
issued a one-year promissory note with interest accruing at 5.06% per annum. On March 21, 2024, Mr. Hatsopoulos amended the terms of the promissory note, dated October 10, 2023, extending the maturity date by one-year, making the maturity date October 10, 2025. On September 18, 2024, we borrowed $500,000 from Mr. Lewis and issued him a one-year promissory note with interest accruing at 4.57% per annum.
On January 14, 2025, we agreed to permit Mr. Lewis to either receive repayment of his note in cash or, at his discretion, convert the balance of the promissory note into shares of our common stock. In the event of such a conversion, the number of shares required to be issued will be determined by dividing the balance due under the promissory note by the average closing price per share of our shares during the thirty-day period prior to the date of conversion.
On February 18, 2025, we amended the promissory notes with Mr. Hatsopoulos to extend the maturity dates for both promissory notes to July 31, 2026. We also agreed to permit Mr. Hatsopoulos to either receive repayment of his notes in cash, or at his discretion, convert the balance(s) due of one or both of the promissory notes into shares of our common stock. In the event of such a conversion, the number of shares we will be required to issue will be determined by dividing the balance(s) due under the promissory note(s) by the average closing price per share of our shares during the thirty-day period prior to the date of conversion.
The loans are required to be repaid in the event of a change of control of the company and upon the occurrence of an event of default under the note, including upon a failure to pay when due the principal and interest when due, or the commencement of voluntary or involuntary bankruptcy or insolvency proceeding.
The loans and terms of the loan agreements were unanimously approved by our Board of Directors.
The loans bear interest on the outstanding principal at the Internal Revenue Service’s Applicable Federal Rate to be determined at the time we issue a promissory note in connection with a loan draw-down. The notes may be prepaid by us at any time. The principal amount of each loan and accrued interest is subject to mandatory prepayment in the event of a change of control of the registrant. The promissory notes are subject to customary events of default and are transferable provided the conditions to transfer set forth in the promissory notes are satisfied by the noteholder. The proceeds of the loans have been used for general working capital purposes and to fund the initial improvements required at our North Billerica facility.
At June 30, 2025, our obligation to Mr. Hatsopoulos under the promissory notes, inclusive of $67,848 of accrued and unpaid interest, was $1,067,848, and was reclassed to long-term liabilities due to the February 18, 2025 amendment. On May 1, 2025, Mr. Lewis elected to convert the promissory note we issued to him in connection with his loan to us in the principal amount of $500,000 together with $14,148 of accrued and unpaid interest into 240,256 shares of our common stock at a per share price of $2.14. The number of shares was determined by dividing the balance due under the promissory note by the average closing price per share of our shares during the thirty-day period prior to the date of conversion. At June 30, 2025 our obligation to Mr. Lewis under the promissory note was retired.
