Nantahala collectively owns, or otherwise controls, approximately 37.3% of our issued and outstanding voting securities. All loans (each a “Loan", and collectively, the “Loans”) under the Credit Facility will bear interest at a rate of 12% for the initial six months after the Closing Date, and at 17% thereafter until the maturity date of 12 months from the Closing Date (the “Maturity Date”).

Upon the Company's receipt by a Lender of a notice stating a Lender's intent to participate in an Exchange, the Company is required to offer to all holders of Series D Preferred the opportunity, but not the obligation, to exchange each such holder’s pro rata portion of shares of the Company's Series D Preferred held by such holder for participation in any subsequent Delayed Draw Loan, upon substantially similar terms as those provided in the applicable notice of Exchange by a Lender. *Notes Payable* Factoring Agreement On February 12, 2020, the Company entered into a factoring agreement (the “Factoring Agreement”) with a former member of the Company’s Board of Directors (the “Factoring Lender”).
