Biotechnology gross margins increased to 80.4% and 80.3% for the quarter and nine months ended March 31, 2007 from 78.8% and 78.2% for the same prior-year periods mainly as a result of changes in product mix.

Included in cost of sales for the quarter and nine months ended March 31, 2007 were $100,000 and $455,000, respectively, related to the sale of acquired inventory compared to $397,000 and $1.3 million, respectively, for the same prior-year periods.

The income tax rate of 35.2% for the quarter ended March 31, 2007 increased from 33.9% for the first and second quarter of fiscal 2007 as a result of changes in state apportionment estimates. Income tax rates are expected to range from approximately 33.5% to 34.5% in the fourth quarter of fiscal 2007.
