#### Transactions with Related Parties
The Board adopted a written related person transaction policy that requires the Audit Committee to approve or ratify any transaction or series of transactions exceeding $120,000 in which our Company is a participant and any related person has a direct or indirect material interest (other than solely as a result of being a director or trustee or less than 10% owner of another entity) ("Related Party Transactions"). Related persons include our directors, director nominees and officers and their immediate family members and persons sharing their households. It also includes persons controlling more than 5% of our outstanding common stock. Subject to certain exceptions in the policy, related parties are required to notify the Audit Committee of the Related Party Transaction for an assessment of whether the transaction or proposed transaction should be permitted. Management also has established procedures for monitoring transactions that could be subject to approval or ratification under the Related Party Transactions policy.

#### Board Practices, Policies and Processes
In deciding whether to approve or ratify the Related Party Transaction, the Audit Committee considers relevant facts and circumstances. The committee takes into account, among other factors, whether the transaction is on terms no more favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Once a Related Party Transaction has been identified, the Audit Committee reviews all of the relevant facts and circumstances and approves or disapproves entry into the transaction. Members of the Audit Committee having an interest in a transaction excuse themselves for the consideration and approval of the transaction in which they have an interest. Certain transactions are exempt from the policy including compensation paid by the Company for service as a director or an officer which is approved by the Compensation Committee or the Board.
