Notes and Line of Credit	(6) 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.

It is our intention to renew this note annually, for as long as we need to pursuant to the terms of our facility lease agreement. Because there were no amounts outstanding at any time during 2018 or 2017, we have recorded no related liability on our balance sheet. During March 2015, we entered into a Business Loan Agreement (the “Line of Credit Agreement”) with Libertyville Bank and Trust Company, a Wintrust Community Bank (“Libertyville”), our primary bank. This Line of Credit Agreement was subsequently amended on April 13, 2015 and was extended on each of March 4, 2016 and February 14, 2017. Under the Line of Credit Agreement, as amended, Libertyville provided a maximum of $300,000 or 75% of our eligible accounts receivable, whichever was less, of revolving credit, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles and fixtures. Interest on any borrowings was the prime rate at the time plus 1%. Availability to draw on the line required us to have at least $1 million in cash, including any amounts borrowed, at Libertyville on the date of any advance. Advances could only occur at the beginning or end of a fiscal quarter and had to be repaid in full within five days of the advance. Borrowings on this line were $300,000 on December 31, 2017. These borrowings were repaid in January 2018. The Line of Credit Agreement expired on March 4, 2018. On March 26, 2018, we executed a new Business Loan Agreement (the “New Line of Credit Agreement”), dated as of March 4, 2018, with Libertyville, which replaces the Line of Credit Agreement with Libertyville that expired on March 4, 2018. Under the New Line of Credit Agreement, Libertyville will provide a maximum of (i) $500,000 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 receivables, inventory, equipment, general intangibles and fixtures. Interest is payable monthly on any advances at a floating interest rate of the prime rate at the time plus 1%. We must have $1 million in cash, inclusive of the borrowed amount, at Libertyville on the date of any advance. Advances may only occur at the beginning or end of a fiscal quarter and must be repaid in full within five business days of the advance. The New Line of Credit Agreement expires in March 2019. While the New Line of Credit Agreement is in effect, we cannot, among other things, engage in any business activities substantially different than those in which we are presently engaged, and there are limitations imposed on our ability to, among other things, incur additional indebtedness for borrowed money, including capital leases, sell, transfer, mortgage, assign, pledge, lease or grant a security interest in or encumber any of our assets, sell with recourse any of our accounts other than to Libertyville, cease operations, merge, transfer, acquire or consolidate with any other entity, change our name, dissolve or transfer or sell collateral outside the ordinary course of business, pay any cash dividends, loan, invest in or advance money or assets to any other person or entity, purchase, create or acquire any interest in any other entity, or incur any obligation as a surety or guarantor other than in the ordinary course of business, in each case without Libertyville’s prior written consent. We borrowed $500 on this line on June 29, 2018 and repaid it on July 2, 2018. The amount outstanding on the loan was $300 on December 31, 2017 which was paid in full on January 9, 2018.

(6) 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 pursuant to the terms of our facility lease agreement. Because there were no amounts outstanding at any time during 2018 or 2017, we have recorded no related liability on our balance sheet.

During March 2015, we entered into a Business Loan Agreement (the “Line of Credit Agreement”) with Libertyville Bank and Trust Company, a Wintrust Community Bank (“Libertyville”), our primary bank. This Line of Credit Agreement was subsequently amended on April 13, 2015 and was extended on each of March 4, 2016 and February 14, 2017. Under the Line of Credit Agreement, as amended, Libertyville provided a maximum of $300,000 or 75% of our eligible accounts receivable, whichever was less, of revolving credit, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles and fixtures.

On March 26, 2018, we executed a new Business Loan Agreement (the “New Line of Credit Agreement”), dated as of March 4, 2018, with Libertyville, which replaces the Line of Credit Agreement with Libertyville that expired on March 4, 2018.
