On December 13, 2012, Superconductor Technologies Inc. (the “Company”), entered into a Placement Agency Agreement (the “Agreement”) with Aegis Capital Corp. (the “Placement Agent”), relating to a registered direct offering (the “Offering”) to accredited investors of up to 6,250,000 shares of its common stock (the “Common Stock”) at an offering price of $0.32 per share. The gross proceeds in the offering were $2 million and the net proceeds were approximately $1.8 million (after deducting Placement Agent fees and certain reimbursements payable by us).

The closing of the Offering occurred on December 18, 2012. The Placement Agent received a fee of 7.0% of the gross proceeds of the Offering, plus a non-accountable expense allowance equal to 1.0% of the gross proceeds of the Offering. As additional compensation to the Placement Agent, the Company issued warrants to purchase 187,500 shares of our common stock at an exercise price per share equal to $0.40, equal to 125% of the offering price (the “Compensation Warrants”). The Compensation Warrants will not be exercisable until the one year anniversary of the Offering and will expire on the four year anniversary of the Offering. The Agreement requires us to indemnify the Placement Agent against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Placement Agent may be required to make because of such liabilities.

The Offering was conducted pursuant to the Company’s registration statement on Form S-3 (File No. 333-172190), which became effective on April 13, 2011, and a related prospectus supplement filed in connection with the Offering.

The foregoing summaries of the Agreement and Compensation Warrants are subject to, and qualified in their entirety by, such documents attached hereto as Exhibits 1.1 and 4.1, respectively, which are incorporated herein by reference. A copy of the opinion of Manatt, Phelps & Phillips, LLP relating to the legality of the issuance of the shares of Common Stock is attached hereto as Exhibit 5.1. The representations and warranties contained in the Agreement are not for the benefit of any party other than the parties to such agreement and are not intended as a document for investors or the public generally to obtain factual information about us.
