The claims set forth in the amended complaint are also covered and resolved by the settlement set forth in the Term Sheet.

The parties to the litigation will use their best efforts to complete the definitive settlement documentation within thirty days. The Company understands that the Plaintiff intends to apply to the Court for an award of attorneys’ fees and expenses in connection with the litigation. The settlement and any award of fees and expenses are subject to approval by the Court. Under the terms of the settlement, the cash payment to the Company from the Company’s insurers is not to be used for any payment of a fee award. It is currently anticipated that the fee award will be paid separately by the Company’s insurers.
