The Board has determined that each member of the Audit Committee is independent and financially literate. The Board has designated Ms. Desmond and Mr. Beecher, who are each independent directors under the Nasdaq listing standings and the SEC's audit committee requirements, as “audit committee financial experts” pursuant to the SEC’s final rules implementing Section 407 of the Sarbanes-Oxley Act. Stockholders should understand that the designation of Ms. Desmond and Mr. Beecher each as an “audit committee financial expert” is an SEC disclosure requirement and that it does not impose upon them any duties, obligations or liabilities that are greater than those imposed on them as members of the Audit Committee and the Board in the absence of such designation. The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended.
