                         CERTIFICATE OF CORRECTION FILED
                        TO CORRECT A CERTAIN ERROR IN THE
                          CERTIFICATE OF DESIGNATION OF
                            JDA SOFTWARE GROUP, INC.
                  FILED IN THE OFFICE OF THE SECRETARY OF STATE
                          OF DELAWARE ON JULY 5, 2006

      JDA Software Group, Inc., a corporation organized and existing under and
by virtue of the General Corporation Law of the State of Delaware (the
"CORPORATION"),

      DOES HEREBY CERTIFY:

      1. The name of the Corporation is JDA Software Group, Inc.

      2. That a Certificate of Designation of Rights, Preferences, Privileges
and Restrictions of Series B Convertible Preferred Stock of JDA Software Group,
Inc. (the "CERTIFICATE") was filed by the Secretary of State of Delaware on July
5, 2006 and that said Certificate requires correction as permitted by Section
103 of the General Corporation Law of the State of Delaware.

      3. The inaccuracy or defect of said Certificate to be corrected is as
follows:

         The definition of Cash Redemption Price and the calculation of amounts
      payable to the holders of Series B Preferred in a Liquidation Event (as
      such terms are defined in the Certificate), are incorrect.

      4. ARTICLE FOURTH, Section 2A of the Certificate is corrected to read in
its entirety as follows:

         2A. Liquidation Events. Upon any liquidation, dissolution or winding up
      of the Corporation (whether voluntary or involuntary) (a "Liquidation
      Event"), each holder of Series B Preferred shall be entitled to be paid
      out of cash legally available for distribution to stockholders, before any
      distribution or payment is made upon any Junior Securities, an amount in
      cash equal to the aggregate Liquidation Value of all shares of the Series
      B Preferred (each, a "Share" and collectively, the "Shares") held by such
      holder plus all accrued and unpaid dividends thereon, and the holders of
      Series B Preferred shall not be entitled to any further payment. If upon
      any such Liquidation Event the Corporation's assets to be distributed
      among the holders of the Series B Preferred are insufficient to permit
      payment to such holders of the aggregate amount which they are entitled to
      be paid under this Section 2A, then the entire assets available to be
      distributed to the Corporation's stockholders shall be distributed pro
      rata among such holders based upon the aggregate Liquidation Value (plus
      all accrued and unpaid dividends) of the Series B Preferred held by each
      such holder.

      5. The definition of "Cash Redemption Price" set forth in Section 12,
"Definitions" is corrected to read in its entirely as follows:

         "Cash Redemption Price" of any Share as of any date of determination
      means the Liquidation Value thereof plus all accrued and unpaid dividends
      thereon.



      IN WITNESS WHEREOF, the Corporation has caused this Certificate to be
signed by Hamish Brewer, its President and Chief Executive Officer, this 20th
day of October, 2006.
