Notes and Lines of Credit	(7) Notes and Line of Credit During July 2014 we entered into a bank-issued letter of credit and related promissory note for up to $30 in borrowings to support our obligations under our facility lease agreement. No borrowings have been incurred under this promissory note. Should any borrowings occur in the future, the interest rate would be the prime rate plus 1%, with the bank having the right to “set off” or apply unpaid balances against our checking account if we fail to meet our obligations under any borrowings under the note. It is our intention to renew this note annually, for as long as we need to do so pursuant to the terms of our facility lease agreement. This note was renewed through July 1, 2021. Because there were no amounts outstanding on the note at any time during 2020 or 2019, we have recorded no related liability on our balance sheet. On March 22, 2019, we executed a Business Loan Agreement, dated as of March 4, 2019 (the “Loan Agreement”), with Libertyville Bank and Trust Company, a Wintrust Community Bank (“Libertyville”), our primary bank, the maturity of which was extended until April 20, 2021 pursuant to an amended and restated Promissory Note executed on June 25, 2020, and dated as of April 4, 2020. Under the Loan Agreement, Libertyville will provided a maximum of (i) $500 or (ii) two times the sum of (a) 75% our eligible accounts receivables and (b) our cash deposited with Libertyville, whichever is less, of revolving credit to us, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles and fixtures. Interest was payable monthly on any advances at a floating interest rate of the prime rate at the time plus 1%. We are required to have $500 in cash, inclusive of the borrowed amount, at Libertyville on the date of any advance. Advances could only occur at the beginning or end of a fiscal quarter and were required to be repaid in full within five business days of the advance. We borrowed $500 on September 29, 2020 and repaid it on October 2, 2020. We borrowed $500 on June 29, 2020 and repaid it on July 1, 2020. We borrowed $500 on March 30, 2020 and repaid it on April 2, 2020. We borrowed $500 on December 31, 2019 and repaid it on January 2, 2020. On November 16, 2018, we entered into a Business Loan Agreement (the “Master Agreement”) with Beachcorp, LLC. Beachcorp, LLC is managed by Bradford T. Whitmore, who, together with his affiliates Grace Brothers, Ltd. and Grace Investments, Ltd., beneficially owned approximately 63% of the outstanding shares of our common stock as of September 30, 2020. The Master Agreement relates to two loan facilities, each evidenced by separate promissory notes, each dated November 16, 2018: a term loan to the Company of up to $500 to be disbursed in a single advance (the “Term Loan”) with a fixed annual interest rate of 8.25%, payable quarterly, accruing from the date of such advance and with principal due on December 31, 2020; and an asset-based revolving loan facility for the Company of up to $2,000 (the “Revolver Facility”), with floating interest accruing at the prime rate plus 3% (8.25% minimum) per year, with a borrowing base consisting of qualified accounts receivable of the Company, and with all principal and accrued interest initially to be due March 31, 2020. On March 23, 2020, the Company and Beachcorp, LLC executed the First Amendment to our Master Agreement that extends the maturities of both the Term Loan and the Revolver Facility to March 31, 2021. On September 8, 2020, the Company executed an updated Promissory Note to, and a Second Amendment to the Business Loan Agreement with Beachcorp, LLC, expanding the capacity of the Revolver Facility from $2,000 to $2,750. The Term Loan and Revolver Facility are secured by all the unencumbered assets of the Company and subordinated to Libertyville’s secured interest under the New Business Loan Agreement. The Master Agreement substantially restricts the Company’s ability to incur additional indebtedness during the terms of both the Term Loan and the Revolver Facility. On September 30, 2020, the balance on the term loan was $500 and the balance on the Revolver Facility was $1,541. There was $34 in related interest expense during the quarter ended September 30, 2020, of which $12 was accrued and $22 paid by the end of the quarter. There was $47 in related interest expense during the quarter ended September 30, 2019, of which $9 was accrued and $18 paid by the end of the quarter. As Beachcorp, LLC is an affiliate of Mr. Whitmore, this amounts to interest to be paid to a related party. On September 30, 2020, the Company had $734 in excess borrowing capacity over the $1,541 balance on the Revolver Facility. The balance of borrowing base, loan amount, and any excess payments required over the available borrowing base will change as frequently as daily, given the operational nature of the elements of the Revolver Facility. On November 20, 2019, we entered into a 2% Secured Convertible Promissory Note with Bradford T. Whitmore in the principal amount of $2,000 (the “Convertible Note”). The principal amount is payable in a single payment on May 15, 2024 (the “Maturity Date”). The principal amount of the Convertible Note accrues interest at the rate of 2.0% per year, which interest is payable semi-annually on the 15th day of May and November, commencing on May 15, 2020. The principal amount and, at the holder’s option, accrued interest under the Convertible Note is convertible at the holder’s option into additional shares of the Company’s common stock in whole or in part and from time to time up to the Maturity Date at a conversion price of $0.20 per share. The convertible note contains a beneficial conversion feature since the Company’s stock was trading at $0.32 per share on the date the Company entered into the agreement. The intrinsic value of the beneficial conversion feature was $1.2 million on November 20, 2019 and is recorded as a discount on the convertible note. The discount will be accreted to the convertible note over the life of the note using the straight-line method. The offset to these discounts will be interest expense. For the three and nine months ended September 30, 2020, the Company accreted $67 and $200, respectively. The balance on the convertible note was $1,030 and $830, net of discounts of $1,103 and $1,170 at September 30, 2020 and December 31, 2019, respectively. On September 30, 2020, the balance on the term loan was $500, the balance on the Revolver Facility was $1,541, the balance on the Convertible Note was $2,000. In the nine months ended September 30, 2020, there was $334 in interest expense relating to these credit facilities held by Beachcorp, LLC. The accrued interest expense balance on these related party credit facilities amounted to $27, and $10, at September 30, 2020 and December 31, 2019, respectively. The obligations under the Convertible Note are secured by a security interest in all of the Company’s personal property pursuant to a Commercial Security Agreement among Mr. Whitmore, the Company and Solésence, LLC, the Company’s sole subsidiary. Given that Beachcorp, LLC is an affiliate of Mr. Whitmore, this amounts to all of this interest being owed to a related party. On April 17, 2020, we entered into a Promissory Note, dated as of April 16, 2020, in favor of Libertyville in the principal amount of $952 for our loan under the PPP. The Company may apply for forgiveness of the amount due on the loan in an amount equal to the sum of the following costs incurred during the 24-week period beginning on the date of the first disbursement of the Loan: (a) payroll costs, (b) any payment of interest on a covered obligation (which shall not include any prepayment of or payment of principal on a covered mortgage obligation), (c) any payment on a covered rent obligation, and (d) any covered utility payment, calculated in accordance with the terms of the CARES Act. No assurance can be provided that the Company will obtain forgiveness of the Loan in whole or in part. The principal amount of the PPP note accrues interest at the rate of 1.00% per year. The Company will be required to pay any unforgiven principle and interest under the PPP note in eighteen equal monthly installments, with the first payment being due on November 17, 2020 and continuing on the same day of each subsequent month until April 17, 2022. On September 30, 2020, the balance under the PPP note was $952.
