Accordingly, upon your execution of this letter amendment below and delivery to the Company by June 30, 2008, the Deferred Stock Award Agreement is hereby amended by adding the following as the last sentence of Section 4:

For purposes of this Section 4, “Effective Registration” shall mean the registration of the shares of Common Stock granted to the Grantee hereunder pursuant to an effective registration statement on Form S-8 or any successor form under the Securities Act of 1933, as amended, and no restrictions under applicable law apply to the resale of such shares of Common Stock at the time of delivery of such shares of Common Stock.”
