Neither JDA, nor, to its knowledge, any person listed in Annex 1 hereto has during the last five years (a) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

As an inducement for JDA to enter into the Merger Agreement (as defined in Item 4 below) with i2, and in consideration thereof, certain beneficial owners of an aggregate of 1,938,080 shares of i2 Common Stock outstanding and subject to rights to acquire and an aggregate of 107,943 shares of i2 Series B 2.5% Convertible Preferred Stock (which are currently convertible into 4,436,501 shares of i2 Common Stock) (the “Stockholders”) entered into voting agreements, each dated as of August 10, 2008, with JDA (the “Voting Agreements”) whereby each Stockholder has agreed to vote with respect to such Stockholder’s shares of i2 Common Stock and Series B 2.5% Convertible Preferred Stock (voting on an as converted to Common Stock basis) and have appointed JDA as such Stockholder’s proxy and attorney-in fact to vote such shares as described in Item 4 below. No funds were used and no funds are to be used by JDA in entering into the Voting Agreements and in acquiring the proxies thereunder. The Voting Agreements and proxies were acquired by JDA as part of the package of agreements as described in Item 4 below. Copies of the Merger Agreement and the forms of Voting Agreements are filed as Exhibits 2.1, 10.4 and 10.5, respectively, to JDA’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on August 11, 2008, as amended by JDA’s Current Report on Form 8-K/A filed with the SEC on August 14, 2008, and are incorporated by reference herein.

Item 4. Purpose of Transaction.

i2, JDA and Iceberg Acquisition Corp., a wholly-owned subsidiary of JDA (“Merger Sub”), have entered into a definitive Agreement and Plan of Merger, dated as of August 10, 2008 (the “Merger Agreement”). Pursuant to the Merger Agreement, Merger Sub will merge with and into i2, with i2 becoming a wholly-owned subsidiary of JDA (the “Merger”). At the effective time of the Merger, each and every share of i2 outstanding common stock (except any shares held by stockholders properly electing appraisal rights) will be converted into the right to receive $14.86 in cash and each and every share of i2 outstanding Series B 2.5% Convertible Preferred Stock (except any shares held by stockholders properly electing appraisal rights) will be converted into the right to receive $1,095.3679 in cash.

As stated in Item 3 above, the Voting Agreements were entered into as an inducement for, and in consideration of, JDA’s entering into the Merger Agreement. The Merger is subject to the approval of the i2 stockholders, clearance under the Hart-Scott-Rodino Antitrust Improvements Act, certain conditions related to the amendment of the indenture to which i2 is party and other closing conditions.

Pursuant to the Voting Agreements, each of the Stockholders agreed, among other things, to vote its shares of i2 Common Stock and Series B 2.5% Convertible Preferred Stock, on an as converted to Common Stock basis, in favor


CUSIP No.		465754208	Page 4 of 6

of the Merger. JDA, and such designees as it may name, were appointed as the Stockholder’s attorney-in-fact and each Stockholder executed an irrevocable proxy to vote such Stockholder’s shares of Common Stock and Series B 2.5% Convertible Preferred Stock, on an as converted to Common Stock basis, for the limited purposes set forth above, with respect to any meeting of the stockholders of i2 or any consent in lieu of any such meeting or otherwise. As of August 7, 2008, the Stockholders beneficially owned 6,374,581 shares of i2 Common Stock in the aggregate, (including 4,436,501 shares of i2 Common Stock which are currently issuable upon the conversion of 107,943 outstanding shares of i2 Series B 2.5% Convertible Preferred Stock), which represents 23% in the aggregate of all of the outstanding shares of i2 Common Stock, based upon 27,714,966 shares of i2 Common Stock, including 21,568,485 of i2 Common Stock outstanding on August 7, 2008 (as represented by i2 in the Merger Agreement) and the following shares of i2 Common Stock and other rights to acquire i2 Common Stock held by the parties to the Voting Agreements as provided to JDA by i2: 1,289,645 shares of i2 Common Stock subject to outstanding unexercised options, 420,335 i2 restricted stock units settleable in shares of i2 Common Stock and 4,436,501 shares of i2 Common Stock currently issuable upon the conversion of 107,943 outstanding shares of i2 Series B 2.5% Convertible Preferred Stock. The holders of i2 Series B 2.5% Convertible Preferred Stock have the right to vote on all matters presented to the holders of i2 Common Stock for a vote, on an as converted to i2 Common Stock basis.

None of the Stockholders were paid any additional consideration in connection with entering into the Voting Agreement. The Stockholders have agreed, subject to limited exceptions, not to sell, transfer, pledge, encumber, assign or otherwise dispose of, or enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, pledge, encumbrance, assignment or other disposition of any shares of i2 Common Stock beneficially owned or acquire by them until the termination of their respective Voting Agreement. The Voting Agreements and proxy terminate upon the earlier to occur of (a) the Effective Time, (b) such date and time as the Merger Agreement shall have been terminated in accordance with its terms, (c) any time JDA provides notice to the stockholder of the termination, and, in one case, (d) an amendment to the Merger Agreement without such stockholder’s prior written consent.

There can be no assurance that the Merger will occur. Should the Merger be consummated, i2 Common Stock will cease to be listed on the NASDAQ Stock Market and will become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended.

The foregoing summary of certain provision of the Merger Agreement and the Voting Agreements is not intended to be complete and is qualified in its entirety by reference to JDA’s Current Report on Form 8-K filed with the SEC on August 11, 2008, as amended by JDA’s Current Report on Form 8-K/A filed with the SEC on August 14, 2008, and the exhibits attached thereto, including the Merger Agreement and the Voting Agreements.
