Summary of JDA SOFTWARE GROUP INC

Item 8.01. Other Events.

As previously disclosed, certain putative class action lawsuits have been filed in connection with the transactions contemplated by the Agreement and Plan of Merger, dated as of November 1, 2012 (the "Merger Agreement"), by and between JDA Software Group, Inc. (the "Company"), RP Crown Parent, LLC and RP Crown Acquisition Sub, LLC.

On December 7, 2012, counsel for the parties in In re JDA Software Group, Inc. Stockholder Litigation, C.A. No. 8049-VCN, which represents the previously consolidated Delaware actions of Neuman v. JDA Software Group, Inc. and New Jersey Building Laborers Annuity Fund v. JDA Software Group, Inc. (the "Consolidated Delaware Action"), and D'Agostino v. JDA Software Group, Inc., Case No. CV 2012-056375, in the Superior Court of the State of Arizona, Maricopa County, (the "Arizona Action") entered into a Binding Memorandum of Understanding (the "Binding MOU") in which they agreed on the terms of a settlement of the Consolidated Delaware Action. The proposed settlement is conditioned upon, among other things, final approval of the proposed settlement by the Court.

Pursuant to the terms of the Binding MOU, the Company has agreed to make certain supplemental disclosures related to the transactions contemplated by the Merger Agreement, all of which supplemental disclosures are set forth in the Schedule 14D-9/A filed by the Company with the Securities and Exchange Commission on December 7, 2012. In addition, in connection with the settlement and as provided in the Binding MOU, the parties contemplate that plaintiffs' counsel will seek an award of attorneys' fees and expenses as part of the settlement, and plaintiffs and the putative stockholder class will release defendants from any and all liability relating to the transactions contemplated by the Merger Agreement. Notwithstanding the Binding MOU, there can be no assurance that the transactions contemplated by the Merger Agreement will be consummated or that the Court will approve the settlement contemplated by the Binding MOU. In such event, the proposed settlement as contemplated by the Binding MOU may be terminated. The settlement will not affect the amount of the consideration that the Company's stockholders are entitled to receive in the transactions contemplated by the Merger Agreement.

Defendants deny all liability with respect to the facts and claims alleged in the Consolidated Delaware Action and the Arizona Action and specifically deny that any breach of fiduciary duty occurred, or that any further disclosure is required to supplement the Schedule 14D-9 filed by the Company on November 15, 2012 or the Schedule TO filed by Parent, Merger Sub and certain of their affiliates on November 15, 2012 in connection with the transactions contemplated by the Merger Agreement under any applicable rule, statute, regulation or law. However, to avoid the risk that the Consolidated Delaware Action and Arizona Action may delay or otherwise adversely affect the consummation of the transactions contemplated by the Merger Agreement, to minimize the expense and uncertainty of defending such action, and to provide additional information to the Company's stockholders at a time and in a manner that would not cause any delay of the transactions contemplated by the Merger Agreement, defendants have agreed to the terms of the proposed settlement described above. The parties further considered it desirable that the Consolidated Delaware Action be settled and the Arizona Action be dismissed with prejudice to avoid the expense, risk, inconvenience and distraction of continued litigation and to fully and finally resolve the settled claims. Plaintiffs in the Consolidated Delaware Action have agreed to stay the Consolidated Delaware Action and to stay and not to initiate any and all other proceedings other than those incident to the settlement itself, including without limitation the Arizona Action, pending final approval by the Court of Chancery of the State of Delaware of the settlement, and to dismiss the Consolidated Delaware Action with prejudice upon final approval by the court of the settlement of the Consolidated Delaware Action and to seek dismissal with prejudice of the Arizona Action no later than five business days after the date on which the order of the Court of Chancery of the State of Delaware approving the settlement becomes final and no longer subject to further appeal or review.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the Binding MOU, which is filed as Exhibit 99.1 hereto and is incorporated herein by reference.
