The following tables present the customers that account for 10% or more of the Company’s revenue and their related segment for
each of the periods presented.  Although certain customers might account for greater than 10% of the Company’s revenue at any one point in
time, the concentration of revenue between a limited number of customers shifts regularly, depending on when revenue is recognized.  The
percentages by customer reflect specific relationships or contracts that would concentrate revenue for the periods presented and do not
indicate a trend specific to any one customer.
