Sales to large chains represent a significant portion of our revenues, and a significant reduction in project sales to these customers could significantly reduce our revenues.
Although in 2004, none of our customers accounted for more then 5% of our revenues, sales to national supermarket and convenience store chains typically are large in size and represent a significant portion of our revenues. Two of our customers each accounted for more than 5% each of our revenues during 2002. Two of our customers (including one of the two mentioned in regard to 2002) accounted for more than 5% each of our revenues during 2003. We anticipate that sales to a few customers in any given reporting period will continue to contribute materially to our revenues in the foreseeable future. A significant reduction in sales to these large chains could significantly reduce our revenues.
