Revenues for the quarter ended June 30, 2007 were $232.8 million, up 17.3% from $198.4 million in the second quarter of 2006.  Acquisitions less than 12 months old contributed $11.0 million to the $34.4 million revenue growth in the second quarter of 2007.

Net income for the second quarter of 2007 was $32.0 million or $0.36 per diluted share compared with net income of $25.2 million or $0.28 per diluted share for the second quarter of 2006.  During the quarter we completed a 2-for-1 stock split.  All historical per share numbers have been adjusted for the split.
