Settlement agreement, description							(1) the Company agreed to adopt an amendment to the Company's Amended and Restated By-Laws, dated April 9, 2015 (the "By-Laws Amendment"), providing that stockholders of the Company owning at least forty percent (40%) of the issued and outstanding Common Stock may request a special meeting of stockholders; (2) the Investor Parties agreed not to take any action to call or otherwise cause a special meeting of stockholders to occur prior to December 30, 2019 (unless the Company had failed to hold the 2018 Annual Meeting); (3) the Company agreed to amend and restate the Company's Rights Agreement, dated August 29, 2018 (the "Amended Rights Agreement"), to confirm that a Distribution Date (as defined in the Amended Rights Agreement) shall not occur as a result of any request by any of the Investor Parties for a special meeting; (4) the Company agreed that prior to the earlier of (A) the completion of the Repurchase and the payment of the Settlement Payment and (B) January 1, 2020, the Board of Directors shall not consist of more than seven (7) directors.
Memorandum of understanding, description				The Company entered into a Memorandum of Understanding (the "MOU") with Susan Paskowitz providing for the settlement of the Stockholder Litigation filed by Ms. Paskowitz on October 11, 2018. The MOU provides for the settlement of the claims by Ms. Paskowitz that (1) the former members of the Board named in the original complaint allegedly breached their fiduciary duties by failing to immediately adopt a rights plan that would have prevented the sale by Joseph F. Hughes and Winifred M. Hughes of an aggregate of 819,491 shares of the Company's common stock to the Investor Parties; (2) the former members of the Board named in the amended complaint allegedly breached their fiduciary duties and failed to adopt proper corporate governance practices; and (3) the Investor Parties acted as "partners" and constituted a "group" in their purchase of shares from Joseph F. Hughes and Winifred M. Hughes and knowingly disseminated false or misleading public statements concerning their status as a group.
Stipulation and agreement of settlement, description	The Company entered into a Stipulation and Agreement of Settlement (the "Stipulation") with Susan Paskowitz in the Stockholder Litigation. The Stipulation retains the terms and conditions of settlement of the Stockholder Litigation contained in the MOU described in the preceding paragraph, with the addition that the Company will pay to plaintiff's counsel an award of attorneys' fees and reimbursement of expenses in the amount of $260,000 (collectively, the "Stockholder Litigation Settlement"). The Stockholder Litigation Settlement is intended to fully, finally, and forever compromise, settle, release, resolve, and dismiss with prejudice the Stockholder Litigation and all claims asserted therein directly against all present and former defendants and derivatively against them on behalf of the Company. The Stockholder Litigation Settlement does not contain any admission of liability, wrongdoing or responsibility by any of the parties, and provides for mutual releases by all parties. Each stockholder of the Company is a member of the plaintiff class unless such stockholder opts out of the class. The Company expects that the full amount of the $260,000 settlement payment will be covered by insurance proceeds. The Stipulation remains subject to approval by the court. The Stipulation is independent of the Settlement Agreement and Share Repurchase Agreement that the Company had entered into with the Investor Parties.
