The Company supplies equipment and services to the oil and gas
industry, which is comprised of a relatively small number of
consumers. Within any given year, sales can vary greatly due to
the large projects that might be underway with any given oil and
gas producer. During the years ended December 31, 2010,
2009, and 2008, no one customer comprised more than 10% of sales.
