On April 28, 2016, Tonix Pharmaceuticals Holding Corp. (the “Company”) entered into a Sales Agreement (the “Sales Agreement”) with Cowen and Company, LLC (“Cowen”) to sell shares of its Common Stock, par value $0.001 (the “Common Stock”), having an aggregate offering price of up to $15,000,000 (the “Shares”) from time to time, through an “at the market” equity offering program (the “ATM Offering”) under which Cowen will act as sales agent.

The offer and sale of the Shares will be made pursuant to the Company’s effective “shelf” registration statement on Form S-3 and an accompanying base prospectus contained therein (Registration Statement No. 333-197824) filed with the Securities and Exchange Commission (the “SEC”) on August 1, 2014 and declared effective by the SEC on August 15, 2014, and a prospectus supplement related to the ATM Offering, dated April 28, 2016.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of any offer to buy the Shares, nor shall there be any offer, solicitation or sale of the Shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state.

Subject to the terms and conditions of the Sales Agreement, Cowen will use its commercially reasonable efforts to sell the Shares, based upon the Company’s instructions, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and rules of The NASDAQ Global Market. The Company will set the parameters for sales of the Shares, including the number of Shares to be sold, the time period during which sales are requested to be made, any limitation on the number of Shares that may be sold in one trading day, and any minimum price below which sales may not be made. Under the Sales Agreement, Cowen may sell the Shares by any method permitted by law deemed to be an “at the market offering,” as defined in Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), including sales made through The NASDAQ Global Market, on any other existing trading market for the Common Stock or to or through a market maker. In addition, if expressly authorized by the Company, Cowen may also sell Shares in negotiated transactions. The Company has no obligation to sell any of the Shares and may at any time suspend offers and sales under the Sales Agreement. The Company and Cowen each have the right, in their sole discretion, to terminate the Sales Agreement at any time upon prior written notice as provided in the Sales Agreement.

The Company will pay to Cowen a commission in an amount up to 3.0% of the gross sales price per Share sold through it as sales agent under the Sales Agreement. In addition, the Company has agreed to reimburse Cowen for certain expenses it incurs in the performance of its obligations under the Sales Agreement up to a maximum of $62,500. The Company has also agreed pursuant to the Sales Agreement to indemnify and provide contribution to Cowen against certain liabilities, including liabilities under the Securities Act.

The foregoing description of the terms of the Sales Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the Sales Agreement, which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.

The legal opinion of Sichenzia Ross Friedman Ference LLP, counsel to the Company, relating to the legality of the issuance and sale of the Shares is filed as Exhibit 5.1 hereto.
