The Company records a provision for estimated returns based on prior product rates of return.  Any significant increase in product quality failure rates and the resulting credit returns could have a material adverse impact on the Company’s operating results for the period or periods in which such returns materialize.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company provides for certain sales incentives.  The Company records a provision for estimated incentives based upon the incentives offered to customers on product related sales in the same period as the related revenues are recorded.  The provision is recorded as a reduction of sales.  The Company also records a provision for estimated sales returns and allowances on product related sales in the same period as the related revenues are recorded.  These estimates are based on historical sales returns, analysis of credit memo data and other known factors.  If the historical data the Company uses to calculate these estimates does not properly reflect future returns, adjustments may be required in future periods.</font></div></div>

Actual results could differ from those estimates.</font></div></div>
