[2] One of the term loans with a certain financial institution contains annual covenants that require the TVN French Subsidiary to maintain a minimum working capital balance and various other financial covenants and restrictions that limit the French Subsidiary’s ability to incur additional indebtedness. The annual covenant is based on French statutory year-end results and the French subsidiary was in compliance for 2015.

[3] The TVN French Subsidiary obtained advances under a credit line with BPI France against a pool of eligible receivables with recourse. The maximum advance under this credit line for receivables is €2 million, less applicable fees, and €200,000 of cash is pledged for this program. This credit line will expire in July 2016 unless renewed pursuant to the terms of the credit agreement and the Company plans to renew the credit line for an additional year prior to its expiration. The TVN French Subsidiary also entered into an accounts receivable financing agreement with GE Capital Cofacredit, (“GE”) on September 27, 2013, which is subject to automatic renewal unless cancelled. GE advances up to 90% of qualified customer invoices and holds the remaining 10% as a guarantee fund up with a minimum of €80,000. In addition, another 10% of outstanding receivables is set aside in a holdback receivable and released upon payments received from the customers. These arrangements are treated as secured borrowings in accordance with FASB ASC 860, Transfers and Servicing.
