AUTHORIZED PREFERRED STOCK

We have 2,000,000 shares of authorized preferred stock, the terms of which may be fixed by our Board of Directors. We presently have no outstanding shares of preferred stock. Our Board of Directors has the authority, without stockholder approval, to create and issue one or more series of such preferred stock and to determine the voting, dividend and other rights of holders of such preferred stock. If we raise additional funds to continue development of AEM-28 and its analogs, or operations, we may issue preferred stock. The issuance of any of such series of preferred stock may have an adverse effect on the holders of common stock.

In connection with the Tax Benefit Preservation Plan (“Benefit Plan”) dated June 24, 2014, between the Company and Computershare (formerly Bank of New York), our Board of Directors approved the designation of 1,000,000 shares of Series A Preferred Stock. The Benefit Plan and the exercise of rights to purchase Series A Preferred Stock, pursuant to the terms thereof, may delay, defer or prevent a change in control without the approval of the Board. In addition to the anti-takeover effects of the rights granted under the Benefit Plan, the issuance of preferred stock, generally, could have a dilutive effect on our stockholders. The Benefit Plan expires June 24, 2016.
