The Company places its temporary cash investments with high credit quality financial institutions and limits the amount of credit exposure to any one financial institution. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the Company’s customer base and their dispersion across many different geographical regions. The Company performs ongoing credit evaluations of its customers, but does not generally require collateral to support customer receivables.</span></div><div style="line-height:120%;text-indent:48px;font-size:12pt;"><span style="font-family:inherit;font-size:12pt;"><br/></span></div>

The Base Rate for any day is a fluctuating rate per annum equal to the highest of (i) the Prime Rate; (ii) the Federal Funds Rate plus .50%; and (iii) the Eurocurrency Rate for an Interest Period of one month plus 100 basis points. The Eurocurrency Rate is the rate per annum obtained by dividing LIBOR for the applicable Interest Period by a percentage equal to 1.00 minus the daily average Eurocurrency Reserve Rate for such Interest Period, as such capitalized terms are defined in the Credit Facility.
