Alan Schmidt (“Schmidt”), a former shareholder of Genaera Corporation (“Genaera”), and a former unitholder of the Genaera Liquidating Trust (the ‘‘Trust’’), filed a purported class action in the United States District Court for the Eastern District of Pennsylvania in June 2012. The lawsuit named thirty defendants, including Abeona, MacroChem Corporation, which was acquired by us in February 2009, Jeffrey Davis, the then-CEO and currently a director of Abeona, and Steven H. Rouhandeh and Mark Alvino, both of whom are our directors (the ‘‘Abeona Defendants’’). With respect to the Abeona Defendants, the complaint alleged direct and derivative claims asserting that directors of Genaera and the Trustee of the Trust breached their fiduciary duties to Genaera, Genaera’s shareholders and the Trust’s unitholders in connection with the licensing and disposition of certain assets, aided and abetted by numerous defendants including the Abeona Defendants. Schmidt seeks monetary damages, disgorgement of any distributions received from the Trust, rescission of sales made by the Trust, attorneys’ and expert fees, and costs. On December 19, 2012, Schmidt filed an amended complaint (the “Amended Complaint”) which asserted substantially the same allegations with respect to the Abeona Defendants. On February 4, 2013, the Abeona Defendants moved to dismiss all claims asserted against them. On August 12, 2013 the court granted the Abeona Defendants’ motions to dismiss and entered judgment in favor of the Abeona Defendants on all claims. On August 26, 2013, Schmidt filed a motion for reconsideration. On September 10, 2013 Schmidt filed a Notice of Appeal with the District Court. On September 17, 2013, Schmidt filed his appeal with the U.S. Third Circuit Court of Appeals (the “Third Circuit”). On September 25, 2013, the District Court denied Schmidt’s motion for reconsideration. On October 17, 2013, Schmidt amended his appeal to include the District Court’s denial of his motion for reconsideration. On March 20, 2014, Schmidt filed his Brief and Joint Appendix. On May 22, 2014, the Abeona Defendants filed their Oppositions to Schmidt’s Brief. On May 29, 2014, Schmidt was granted an extension of time until June 23, 2014 to file his Reply Brief and filed his Reply Brief on that date. The Third Circuit held oral argument on September 12, 2014. On October 17, 2014, in a split decision, the Third Circuit reversed the District Court’s decision holding, among other things, that the District Court’s determination that the Amended Complaint was time-barred on statute of limitations grounds was premature. The Third Circuit did not rule upon any of the other grounds for dismissal advanced in the District Court and on appeal. The Third Circuit remanded the case to the District Court for further proceedings. On January 6, 2015, the District Court ordered the parties to file supplemental briefs on all remaining arguments for dismissal, and further ordered that a hearing on the motions to dismiss would be held on February 3, 2015. On January 23, 2015, the Abeona Defendants filed their Supplemental Brief. At the February 3, 2015, hearing, Schmidt sought and was granted leave to amend his complaint for a second time. Schmidt filed his Second Amended Complaint on February 3, 2015. The Second Amended Complaint asserts substantially the same factual allegations with respect to the Abeona Defendants, but eliminates all causes of action against the Abeona Defendants except for aiding and abetting the Genaera directors’ and officers’ purported breaches of fiduciary duties, a claim for “punitive damages” and a claim for rescission of a settlement agreement between the Trust and the Abeona Defendants. On March 20, 2015, the Abeona Defendants filed a motion to dismiss the Second Amended Complaint. On November 10, 2015, the District Court granted the Abeona Defendant’s motion and dismissed the action in its entirety. On November 11, 2015, Schmidt filed a Notice of Appeal with the District Court. We intend to continue contesting the claims vigorously.
