Stockholder Litigation
Class Action agreement		Company will pay $5.0 million to settle the Class Action
Company's Directors and Officers ("D&O") Insurance Agreement		Company entered into an agreement with the carrier of the first $5.0 million layer of the Company’s D&O insurance. Pursuant to this agreement, the Company accepted a payment of $3.9 million from the first layer insurance carrier in satisfaction of the carrier’s obligations to the Company under the first layer D&O insurance policy. The combined costs of (i) defense of the Class Action and the Derivative Action, and (ii) the proposed $5.0 million settlement of the Class Action exceeds $3.9 million, and the Company is responsible for paying the next $1.1 million of costs, settlement amounts or liability up to $5.0 million, before the next layer of the Company’s D&O insurance might cover the Company. This $5.0 million payment, when and if made, will negatively impact its cash flows and its cash reserves when paid. In addition, as part of the October 2012 agreement with the carrier, the Company agreed to indemnify the carrier of the first layer of D&O insurance against potential claims by certain named insured persons under the first layer D&O insurance policy. The Company cannot predict the likelihood or the outcome of any such claims by the named insureds.
