(1): Approximately 33% of annual rent expense is included in the computation. The Company believes this is a reasonable estimate of the interest factor in its leases, which is not material. The underlying rent amounts were $583,000, $677,000, $673,000, $670,000, $334,000, $652,000, and $468,000 for the nine months ended September 30, 2007, the years ended December 31, 2006, 2005 and 2004, the six months ended December 31, 2003, and the years ended June 30, 2003 and 2002, respectively.
