* Compuware divested its Quality and DevPartner product lines during the first quarter of fiscal 2010.  For comparison purposes, the Products Commitments schedule excludes Quality and DevPartner license revenue, maintenance revenue and product commitments from the quarter ended March 31, 2009 period and the twelve months ended March 31, 2010 and 2009 periods.

As Compuware continues to emphasize solution selling, deals are becoming more complex, increasing the likelihood that software transactions will be recognized ratably over the maintenance term. Therefore to understand the health of Compuware's software business, we believe it is important to also consider the amount of product commitments during the reported periods.
