ITEM 5. OTHER EVENTS

     On March 12, 2000, i2 Technologies, Inc. ("i2"), Hoya Merger Corp., a
wholly owned subsidiary of i2, and Aspect Development Inc. ("Aspect") entered
into an Agreement and Plan of Reorganization (the "Aspect Merger Agreement")
pursuant to which Aspect will become a wholly owned subsidiary of i2. As a
result of the Aspect merger, each outstanding share of Aspect common stock will
be converted into the right to acquire .55 shares of i2 common stock, taking
into account Aspect's 2-for-1 stock split that became effective March 13, 2000.

     Also on March 12, 2000, i2, Starfish Merger Corp., a wholly owned
subsidiary of i2, and SupplyBase, Inc. ("SupplyBase") entered in an Agreement
and Plan of Reorganization (the "SupplyBase Merger Agreement"), pursuant to
which SupplyBase will become a wholly owned subsidiary of i2. As a result of
the SupplyBase merger, i2 will issue approximately 1.8 million shares of i2
common stock in exchange for all of SupplyBase's outstanding capital stock and
stock options.

     A copy of i2's, Aspect's and SupplyBase's joint press release is
incorporated herein by reference to i2's Rule 425 filing on March 13, 2000.

     Each merger is intended to constitute a reorganization under Section 368(a)
of the Internal Revenue Code of 1986, as amended, and to be accounted for as a
purchase transaction. Consummation of the Aspect merger is subject to various
conditions, including, among other things, receipt of the necessary approvals of
the stockholders of Aspect and i2. Consummation of the SupplyBase merger is
subject to various conditions, including, among others, the receipt of the
necessary approval of the stockholders of SupplyBase.

     The foregoing description of the merger agreements, and the transactions
contemplated thereby do not purport to be complete and are qualified in their
entirety by reference to each merger agreement.

     All stockholders should read the joint proxy statement/prospectus
concerning the Aspect merger that will be filed with the SEC and mailed to
stockholders. The joint proxy statement/prospectus will contain important
information that stockholders should consider before making any decision
regarding the Aspect merger. You will be able to obtain the joint proxy
statement/prospectus, as well as other filings containing information about i2
and Aspect, without charge, at the SEC's Internet site (http://www.sec.gov).
Copies of the joint proxy statement/prospectus and the SEC filings that will be
incorporated by reference in the joint proxy statement/prospectus will also be
available, without charge, by contacting the Secretary of the appropriate
company.
