License revenue for the September quarter dropped by 17.2 percent over the prior year, according to a preliminary statement issued by Exact Software. Exact said that was a lot better than the first half when the same source of income dropped by 30.4 percent over the first half of 2008.  However, the company, which is based in the Netherlands, said that business in North America remains to be the most affected by economic conditions while strong growth continues in its home country.  It did not provide any numbers for the regions. Total revenue dropped 8.6 percent to $81.3 million while EBITDA rose to about $19.2 million. (Percentages are calculated from the change in results as reported in euros.) That improvement stemmed from cost reduction and efficient improvement measures made in 2008. The company said it continues to focus on EBITDA protection and cash collection, but that it is also gearing up for an economic rebound.
