Audit Committee Pre-Approval Policies and Procedures

Our audit committee charter provides that our audit committee must comply with SEC rules to maintain auditor independence as set forth in Rule 2-01(c)(7)(i) of Regulation S-X. The Audit Committee has a policy to pre-approve all audit and permissible non-audit services to be provided by our independent registered public accounting firm. All the services above were approved in advance by our Board of Directors.
