As previously disclosed, four putative class action lawsuits were filed in the Los Angeles County Superior Court and the Delaware Court of Chancery (the “Merger Litigation”). The Merger Litigation relates to the Agreement and Plan of Merger, dated as of May 24, 2011 (the “Merger Agreement”), by and among California Pizza Kitchen, Inc., a Delaware corporation (the “Company”), CPK Holdings Inc., a Delaware corporation, (“Parent”), and CPK Merger Sub Inc., a Delaware corporation (“Purchaser”). The complaints filed with respect to the Merger Litigation name as defendants the members of the Board of Directors of the Company, as well as the Company, Parent and Purchaser.

On June 27, 2011, solely to avoid the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, the parties to the actions pending in the Delaware Court of Chancery and Los Angeles County Superior Court signed a memorandum of understanding regarding a proposed settlement of all claims asserted in the actions related to the transactions contemplated by the Merger Agreement. This memorandum of understanding provides, among other things, that the parties will seek to enter into a stipulation of settlement which provides for the release of all asserted claims. The asserted claims will not be released until such stipulation of settlement is approved by the court. There can be no assurance that the parties will ultimately enter into a stipulation of settlement or that the court will approve such settlement even if the parties were to enter into such stipulation. Additionally, as part of the memorandum of understanding, the Company has agreed to make certain additional disclosures related to the proposed merger, which are set forth below. Finally, in connection with the proposed settlement, plaintiffs intend to seek, and the defendants have agreed to pay, an award of attorneys fees and expenses in an amount to be determined by the Los Angeles County Superior Court. This payment will not affect the amount to be paid to Company stockholders pursuant to the terms of the Merger Agreement.

The additional disclosures in this Current Report on Form 8-K supplement the disclosure contained in the Schedule 14D-9 filed by the Company with the Securities Exchange Commission (“SEC”) on June 8, 2011 and mailed to the Company’s stockholders on or about June 8, 2011 (as amended, the “Schedule 14D-9”), and should be read in conjunction with the disclosures contained in the Schedule 14D-9. Nothing in this Current Report on Form 8-K, the memorandum of understanding or any stipulation of settlement shall be deemed an admission of the legal necessity or materiality of any of the disclosures set forth herein. Capitalized terms used herein, but not otherwise defined, shall have the meanings ascribed to such terms in the Schedule 14D-9.

The following additional disclosures supplement the existing disclosures contained under the caption “Item 4. The Solicitation or Recommendation—Background of the Offer and Merger; Reasons for Recommendation—Background of the Offer and Merger” beginning on page 12 of the Schedule 14D-9:
