On May 16, 2014, Stereotaxis, Inc. (the “Company”) entered into a Controlled Equity Offering^SM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor”), as sales agent, pursuant to which the Company may offer and sell, from time to time, through Cantor shares of its common stock, par value $0.001 per share, having an aggregate offering price of up to $18.0 million.

The Company is not obligated to sell any shares under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, Cantor will use commercially reasonable efforts consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations and the rules of The NASDAQ Capital Market to sell shares from time to time based upon the Company’s instructions, including any price, time or size limits specified by the Company. Under the Sales Agreement, Cantor may sell shares by any method deemed to be an “at-the-market” offering as defined in Rule 415 under the U.S. Securities Act of 1933, as amended, or any other method permitted by law, including in privately negotiated transactions. Cantor’s obligations to sell shares under the Sales Agreement are subject to satisfaction of certain conditions, including customary closing conditions for transactions of this nature. The Company will pay Cantor a commission of 3.0% of the aggregate gross proceeds from each sale of shares and has agreed to provide Cantor with customary indemnification and contribution rights. Sales of shares of common stock under the Sales Agreement will be made pursuant to the registration statement on Form S-3 (File No. 333-192606), which was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on December 11, 2013, and a related Prospectus Supplement filed with the SEC on May 16, 2014.

The foregoing summary of the Sales Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Sales Agreement, which is filed herewith as Exhibit 1.1.

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