Tax Items

Dendrite currently estimates its full year 2006 tax provision to be in the range of $8 to $12 million. In addition, the Company is in the process of completing a worldwide historical analysis of its income tax accounting which includes the impact of the January 1, 2007 adoption of FIN 48, as well as other tax matters.
