On August 17, 2006, AmeriCredit Financial Services, Inc.

The amendment extended the commitment termination date from August 17, 2006 through August 16, 2007.  The amendment also increased the facility limit from $500 million to $600 million for the period of August 17, 2006 through February 17, 2007, and for the period from February 18, 2007 through the commitment termination date, the facility limit will revert to $500 million.
