Transaction Valuation(1)	Amount of Filing Fee(2)
$1,107,651,252	$126,937

Chang’s China Bistro, Inc. (“P.F. Chang’s”) outstanding multiplied by the offer price of $51.50 per share, (ii) 737,592 shares of common stock, par value $0.001 per share, of P.F. Chang’s, issuable pursuant to outstanding options with an exercise price less than the offer price of $51.50 per share, multiplied by the offer price of $51.50 per share minus the weighted average exercise price for such options of $38.95 per share and (iii) 44,500 outstanding restricted stock units, multiplied by the offer price of $51.50 per share. The calculation of the filing fee is based on information provided by P.F. Chang’s as of May 4, 2012.
