Footnotes

F1: Pursuant to the "lowest in, highest out" method of calculating profit under Section 16(b), the two reported sales resulted in a short-swing profit of $247,113.49 when matched against the Reporting Persons' purchases of 16,500 shares at a price of $7.813 per share on 8/28/2007, 8,200 shares at a price of $7.8429 per share on 8/29/2007, and a portion of 20,000 shares at a price of $8.0645 on 8/27/2007. This temporary short-swing liability was immediately remedied on the date of the filing of this Form 4 as Reporting Persons informed Issuer of their liability and returned the full amount of said profit (inclusive of transaction costs) to Issuer via its wire instructions. Therefore, Reporting Persons in effect realized no profit from the reported short-swing transactions and is in full compliance with Section 16(b).
