CALCULATION OF FILING FEE

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

(1) Estimated for purposes of calculating the filing fee only. The transaction valuation was calculated by adding the sum of (i) 21,283,548 shares of common stock, par value $0.001 per share, of P.F. 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.

(2) The filing fee was calculated in accordance with Rule 0-11 under the Securities Exchange Act of 1934 by multiplying the transaction value by 0.00011460.

(“Centerbridge”), to purchase all of the outstanding shares of common stock, par value $0.001 per share (the “Shares”), of P.F. Chang’s China Bistro, Inc., a Delaware corporation (“P.F. Chang’s”), at a purchase price of $51.50 per Share, net to the seller in cash, without interest thereon and less any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated May 15, 2012 (which, together with any amendments and supplements thereto, collectively constitute the “Offer to Purchase”) and in the related Letter of Transmittal, copies of which are attached to the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively (which, together with the Offer to Purchase, as each may be amended or supplemented from time to time, collectively constitute the “Offer”). The Schedule TO (including the Offer to Purchase) and the Solicitation/Recommendation Statement on Schedule 14D-9 filed with the SEC by P.F. Chang’s on May 15, 2012 contain important information about the Offer, all of which should be read carefully by P.F. Chang’s stockholders before any decision is made with respect to the Offer. The Offer is made pursuant to the Agreement and Plan of Merger, dated as of May 1, 2012, among Parent, Purchaser and P.F. Chang’s.

Documentation relating to the Offer has been mailed to stockholders of P.F. Chang’s and may be obtained at no charge at the website maintained by the SEC at www.sec.gov and may also be obtained at no charge by directing a request by mail to Georgeson Inc., 199 Water Street, 26th Floor, New York, New York 10038-3560, or by calling toll-free at (866) 300-8594.

All information set forth in the Offer to Purchase and the related Letter of Transmittal is incorporated by reference in answer to Items 1 through 12 in the Schedule TO, except those items as to which information is specifically provided herein. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Offer to Purchase.

Items 1-11.

The Offer to Purchase is hereby amended by:

Amending and supplementing the information set forth in Section 16 of the Offer to Purchase entitled “Certain Legal Matters; Regulatory Approvals” by inserting the following text after the second paragraph under the heading “Legal Proceedings”:

On May 17, 2012, the complaint in the Jeanty action was amended by, among other things, adding a claim alleging that the members of the P.F. Chang’s Board breached their fiduciary duties to stockholders of P.F. Chang’s by failing to provide full and fair disclosure regarding the transaction.

On May 18, 2012, another putative shareholder class action suit captioned Coyne v. P.F. Chang’s China Bistro, Inc., et al., C.A. No. 7551- was filed in the Delaware Court of Chancery seeking to enjoin the proposed acquisition of P.F. Chang’s by affiliates of Centerbridge Partners. The complaint names P.F. Chang’s, the P.F. Chang’s Board, Centerbridge Partners, Parent and Purchaser as defendants. The complaint alleges that the members of the P.F. Chang’s Board breached their fiduciary duties to stockholders of P.F. Chang’s by, among other things, agreeing to sell P.F. Chang’s to Centerbridge Partners for an inadequate price and pursuant to an unfair process, failing to provide full and fair disclosure regarding the transaction and acting to put their personal interests ahead of the interests of stockholders of P.F. Chang’s. The complaint also alleges that Centerbridge Partners, Parent and Purchaser aided and abetted the alleged breaches of fiduciary duties by the P.F. Chang’s Board. The complaint seeks injunctive relief and an award of attorneys’ and other fees and costs, in addition to other relief.

Item 12. Exhibits.

Item 12 of the Schedule TO is hereby amended by adding the following exhibits thereto:
