Due to a more promotional environment in May 2007 versus May 2006, the Company is reiterating its second quarter guidance of $0.17 to $0.19 per diluted share. This guidance assumes a second quarter low single digit same-store sales increase and includes the previously reported $0.01 per share impact to second quarter earnings as a result of the compensation arrangements for the Company's new Chief Executive Officer, Sally Frame Kasaks.

As of the end of fiscal May 2007, the Company had closed all of the previously announced 74 underperforming demo stores. The sales results, earnings estimates and store counts reported in this release do not include the impact of the 74 demo store closures.
