The Company, and its wholly owned subsidiary Sonomed, Inc., entered into an Inventory Advance Agreement as of December 29, 2016 (the "Agreement"), with CDS Business Services, Inc., doing business as Newtek Business Credit ("Newtek"). Newtek may in its discretion make loans against the Company’s Eligible Inventory in an aggregate amount outstanding at any time up to the lesser of (i) fifty percent (50%) of the Inventory Value or (ii) the Inventory Advance Limit, as those terms are defined in the Agreement, which is currently $250,000. The credit agreement renews annually and can be terminated upon 90 days written notice from the Company or 30 days written notice from NewTek.

Newtek will maintain reserves against Company’s availability for advances and may maintain reserves against the Company’s accounts and/or ineligible inventory as well, or maintain a cash collateral deposit account, as NewTek in its discretion deems appropriate. Newtek may also increase such reserves or reduce its advance percentages based on eligible inventory without declaring an event of default and without prior notice, if it determines, in its discretion, that such increase in reserves or reduction is necessary, including, without limitation, to protect its interest in the collateral and/or against diminution in the value of any collateral, and/or to insure the prospect of payment or performance by Company of its obligations to Newtek are not impaired. Interest will accrue on the daily balance at the per annum rate of 5.00% above the Prime Rate (currently 4.25%), but not less than 5.0%. The current annual interest rate is 9.25% as of December 31, 2017. The Company’s obligations will, at the option of Newtek, (i) from and after the occurrence of an event of default, or (ii) if the Company’s obligations are not paid in full by the termination date, bear interest at the per annum rate of 10.00% above the prime rate. All interest payable by under the financing documents will be computed on the basis of a 360-day year for the actual number of days elapsed on the daily balance. In consideration of monitoring, ledgering and other administrative functions undertaken by Newtek in connection with the Company’s inventory, and the merchant processor, Company is obligated pay Newtek a monthly collateral monitoring fee calculated by multiplying (i) seventy basis points (0.7% ) (approximately an annual rate of 8.5% (except during the existence of an Event of Default at which time it shall be 1% ) by (ii) the amount of the average daily balances during the calendar month preceding the month for which the calculation is made. As of December 31, 2017 and June 30, 2017, the line of credit balance is at $190,000 and $250,000, respectively. The line of credit interest expense is $10,175 and $0 for the three-month period ended December 31, 2017 and 2016, respectively. The line of credit interest expense is $20,511 and $0 for the six-month period ended December 31, 2017 and 2016, respectively.
