     Voting Agreement and Irrevocable

                                       4
<PAGE>

     Proxy. Certain provisions of the Voting Agreement and Irrevocable Proxy are
     described below.

The description contained in this Item 4 of the transactions contemplated by the
Merger Agreement is qualified in its entirety by reference to the full text of
the Merger Agreement, a copy of which is attached to this Schedule 13D as
Exhibit 99.1.

     (c) Not applicable.

     (d) If the Merger is consummated, Aspect will become a wholly-owned

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

     (a)-(b) As a result of the Voting Agreement and the Irrevocable Proxy
     relating to Mr. Wadhwani's shares, i2 has shared power to vote shares of
     Aspect Common Stock beneficially owned by Mr. Wadhwani for the limited
     purpose of voting (i) in favor of adoption of the Merger Agreement and any
     proposal or action which would, or could reasonably be expected to,
     facilitate the Merger; (ii) against approval of any proposal made in
     opposition to or competition with consummation of the Merger and the Merger
     Agreement; (iii) against any Company Takeover Proposal (as defined in the
     Merger Agreement) with any party other than i2 or an affiliate of i2 as
     contemplated by the Merger Agreement; (iv) against any liquidation or
     winding up of Aspect; and (v) against any other proposal or action which
     would, or could reasonably be expected to, impede, frustrate, prevent,
     prohibit or discourage the Merger.  Mr. Wadhwani has retained the right to
     vote his shares of Aspect Common Stock on all matters other than those
     identified in the Voting Agreement and Irrevocable Proxy.  The Voting
     Agreement also prohibits Mr. Wadhwani from selling or otherwise disposing
     of shares of Aspect Common Stock for certain time periods, except in
     certain instances.  The Voting Agreement and Irrevocable Proxy terminates
     upon the first to occur of the closing of the Merger or the termination of
     the Merger Agreement.

     The 4,804,500 issued and outstanding shares of Aspect Common Stock, all of
     which are covered by Mr. Wadhwani's Voting Agreement and Irrevocable Proxy,
     constitute approximately 15.7% of the issued and outstanding shares of
     Aspect Common Stock as of March 12, 2000. Any additional shares of Aspect
     Common Stock acquired by Mr. Wadhwani after the date of this

                                       5

     Schedule 13D and on or before the record date for persons entitled to
     notice of, and to vote at, a meeting of Aspect's stockholders at which the
     Merger Agreement and the Merger will be voted upon (whether such shares are
     acquired upon the exercise of stock options or otherwise), must also be
     voted in accordance with the terms of the Voting Agreement and Irrevocable
     Proxy.

     The description contained in this Item 5 of the transactions contemplated
     by the Voting Agreement and Irrevocable Proxy is qualified in its entirety
     by reference to the full text of the Voting Agreement and Irrevocable
     Proxy, a copy of which is attached to this Schedule 13D as Exhibit 99.2.

the executive officers and directors of i2.

owned by i2 or any person listed on Schedule I to this Schedule 13D.

criminal proceeding (excluding traffic violations or similar misdemeanors).

During the past five years, to Mr. Wadhwani's knowledge, neither i2 nor any
person listed on Schedule I to this Schedule 13D has been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction as a
result of which such person was or is subject to a judgment, decree or final
order enjoining future violations of or prohibiting or mandating activity
subject to federal or state securities laws or finding any violation with
respect to such laws.

         the Exchange Agent and shall be included in the Exchange Fund, in each
         case until the holder of record of such Company Certificate shall
         surrender such Company Certificate. Subject to the effect of applicable
         escheat and unclaimed property laws, following surrender of any such

         upon the surrender for exchange of Company Certificates, and such
         fractional share interests will not entitle the owner thereof to vote
         or to any other rights of a stockholder of Parent.  Notwithstanding any
         other provision of this Agreement, each holder of shares of Company
         Common Stock converted pursuant to the Merger who would otherwise have
         been entitled to receive a fraction of a share of Parent Common Stock
         (after taking into account all Company Certificates representing shares
         of Company Common Stock owned by or registered in the name of such
         holder) shall receive, in lieu thereof, cash (without interest) in an
         amount equal to such fractional part of a share of Parent Common Stock
         multiplied by the average of the last reported sales prices of Parent
         Common Stock, as reported on the Nasdaq National Market, on each of the
         ten (10) trading days immediately preceding the date of the Effective

         Common Stock and any dividends or distributions with respect to Parent
         Common Stock.

                         ------------
         Corporation shall be liable to any holder of shares of Company Common
         Stock or Parent Common Stock, as the case may be, for any shares of
         Company Common Stock or Parent Common Stock (or cash in lieu of any
         fractional share or dividends or distributions with respect thereto)
         properly delivered to a public official pursuant to any applicable
         abandoned property, escheat or similar law.

                         ------------------
         Corporation shall be entitled to deduct and withhold from the

         holder of shares of Company Common Stock such amounts as Parent or the
         Surviving Corporation is required to deduct and withhold with respect
         to the making of such payment under the Internal Revenue Code or any
         provision of state, local or foreign tax law.  To the extent that
         amounts are properly so withheld by the Surviving Corporation or
         Parent, as the case may be, such withheld amounts shall be treated for
         all purposes of this Agreement as having been paid to the holder of the
         shares of Company Common Stock in respect of which such deduction and
         withholding was made by the Surviving Corporation or Parent, as the
         case may be.

         foreign), (B) any liability for the payment of any amounts of the type
         described in clause "(A)" as a result of being a member of an
         affiliated, consolidated, combined or unitary group for any Taxable
         period, and (C) any liability for the payment of any amounts of the

         ------
         estimated tax returns and reports, withholding tax returns and reports
         and information reports and returns) required to be filed with respect
         to Taxes.

         Taxes due and payable for Taxable periods (or portions thereof) through
         the date of the Company Balance Sheet and (iii) no Tax liabilities
         accruing after the date of the Company Balance Sheet other than
         liabilities arising from the ordinary course of business.  Neither the
         Internal Revenue Service (the "IRS") nor any other Taxing Authority has
                                        ---

         with an unaffiliated party, nor does Company or any of its Subsidiaries
         have any liability or potential liability to another party under any
         such agreement.  Neither Company nor any of its Subsidiaries has ever
         been a member of a consolidated, combined or unitary group of which
         Company was not the ultimate parent corporation.

                    (c)  There is no agreement, contract or arrangement to which
         Company is a party that would reasonably be expected, individually or
         collectively, as a result of the Merger, this Agreement and subsequent
         events, to result in the payment of any amount that would not be
         deductible by reason of Section 280G of the Internal Revenue Code.

on the date of this Agreement (the "Parent Disclosure Schedule").  The Parent
                                    --------------------------
Disclosure Schedule shall be arranged in paragraphs corresponding to the
numbered sections contained in this Article IV and the disclosure in any
                                    ----------
paragraph shall qualify other sections in this Article IV only to the extent

and operate its property and to carry on its business as now being conducted and
as proposed to be conducted, and is duly qualified to do business and is in good
standing (with respect to jurisdictions which recognize the concept of good
standing) as a foreign corporation in each jurisdiction in which the failure to
be so qualified would have a Parent Material Adverse Effect, as defined in
Section 9.03(b). Neither Parent nor any of its Subsidiaries directly or
- ---------------
indirectly owns any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for any equity or similar interest in, any

          business, and (ii) repurchase rights of Parent under the Parent Stock

nor any of its Subsidiaries is subject to any orders, decrees, injunctions or
other arrangements with any Governmental Entity (other than those of general
applicability), or is subject to any indemnity or other agreement with any third
party, relating in either case to liability under any Environmental Law for
release of Hazardous Substances.  To the knowledge of Parent, there are no
circumstances or conditions involving Parent or any of its Subsidiaries that
will, solely with the passage of time, imminently result in a Parent Material
Adverse Effect pursuant to any Environmental Law.

          4.11 Employee Benefit Plans. With respect to the Parent Employee Plans
(as defined in Section 6.12(d)), individually and in the aggregate, Parent is
not subject to any material unsatisfied liability for (i) violation of ERISA,
the Internal Revenue Code or any other applicable law, (ii) for an excise or
other penalty tax or penalty under any such law, or (iii) under Title IV of
ERISA and, to the knowledge of Parent, no event has occurred and there exists no
set of circumstances which could reasonably be expected to result in any such
liability.  With respect to the Parent Employee Plans, individually and in the
aggregate, there are no funded benefit obligations for which contributions have
not been made or properly accrued and there are no unfunded benefit obligations
which have not been accounted for by reserves, or otherwise properly footnoted
in accordance with GAAP, on the financial statements of Parent.

          4.12 Compliance With Laws. Parent and each of its Subsidiaries is in
substantial compliance with, is not in violation in any material respect of and
has not received any written notice of violation with respect to, any federal,
state or local statute, law or regulation with respect to the conduct of its
business, or the ownership or operation of its business which by its terms could
reasonably be expected to subject Parent and its Subsidiaries to material
financial or other penalties or criminal liability.

          4.13 Tax Matters. To the knowledge of Parent after good faith
consultation with its independent accountants, neither Parent nor any of its
Affiliates has taken or agreed to take any action which would prevent the Merger
from constituting a transaction qualifying as a reorganization under Section
368(a) of the Internal Revenue Code.

supplied or to be supplied by Company which is or will be contained in any of
the foregoing documents.

reasonably likely imminently to have, a Company Material Adverse Effect (in the
case of Company) or a Parent Material Adverse Effect (in the case of Parent or
Merger Sub) or which will likely render it impossible for one or more of the
conditions set forth in Article VII to be satisfied; provided, however, that no
                        -----------                  --------  -------
such notification shall affect the representations, warranties, covenants or
agreements of the parties (or remedies with respect thereto) or the conditions
to the obligations of the parties under this Agreement.

         with the SEC, the Joint Proxy Statement/Prospectus, and Parent will
         prepare and file with the SEC the Registration Statement, in which the
         Joint Proxy Statement/Prospectus will be included as a prospectus. Each
         of Parent and Company shall provide promptly to the other such
         information concerning its business and financial statements and
         affairs as, in the reasonable judgment of the providing party or its
         counsel, may be required or appropriate for inclusion in the Joint
         Proxy Statement/Prospectus and the Registration Statement, or in any
         amendments or supplements thereto, and to cause its counsel and
         auditors to cooperate with the other's counsel and auditors in the
         preparation of the Joint Proxy Statement/Prospectus and the
         Registration Statement. Each of Company and Parent will respond to any
         comments of the SEC, and will use its commercially reasonable efforts
         to have the Registration Statement declared effective under the
         Securities Act as promptly as practicable after such filing, and
         Company and Parent will cause the Joint Proxy

                                      31
<PAGE>

         Statement/Prospectus to be mailed to their respective stockholders at
         the earliest practicable time after the Registration Statement is
         declared effective by the SEC. As promptly as practicable after the
         date of this Agreement, each of Company and Parent will prepare and

         related securities laws or NASD or National Market System rules,
         regulations or bylaws in order to consummate the Merger and the
         transactions contemplated by this Agreement. Each of Company and Parent
         will notify the other promptly upon the receipt of any comments from
         the SEC or its staff and of any request by the SEC or its staff for
         amendments or supplements to the Registration Statement or the Joint
         Proxy Statement/Prospectus and will supply the other with copies of all
         correspondence between such party or any of its Representatives, on the
         one hand, and the SEC or its staff, on the other hand, with respect to
         the Registration Statement, the Joint Proxy Statement/Prospectus or the
         Merger. Each of Company and Parent will cause all documents that it is
         responsible for filing with the SEC under this Section 6.01 to comply
                                                        ------------
         in all material respects with all applicable requirements of law and
         the rules and regulations promulgated thereunder. Notwithstanding any
         other provision of this Agreement, nothing herein shall require Parent
         to qualify to do business in any jurisdiction in which it is not now so
         qualified or to file a general consent to service of process under any
         applicable state securities laws in connection with the issuance of
         Parent Common Stock in the Merger.

                   (b) If eligible, Parent shall use commercially reasonable
         efforts (i) to obtain an exemption from compliance with applicable
         Nasdaq Stock Market stockholder voting requirements promulgated by the
         NASD in connection with the Merger, or (ii) otherwise to make
         arrangements such that Parent need not solicit the vote or hold a
         meeting of its stockholders in connection with the Merger or the
         issuance of shares of Parent Common Stock pursuant thereto.  If Parent
         obtains such an exemption or otherwise makes such arrangements, all
         references to "Joint Proxy Statement/Prospectus" in this Agreement
         shall be deemed to be changed to "Proxy Statement/Prospectus" and all
         other appropriate changes shall be deemed to be made to this Agreement
         to reflect the fact that a meeting of Parent's stockholders is not
         required.

         6.02  No Solicitation By Company.

                   (a) Until the earlier of the Effective Time or a valid
         termination of this Agreement pursuant to Article VIII, Company will

         regarding, or furnish to any person any information with respect to, or

         proposal that constitutes or would reasonably be expected to lead to,
         any Company Takeover Proposal, (iii) authorize, approve or recommend
         any Company Takeover Proposal, or (iv) enter into any letter of intent
         or similar document or any contract, agreement or commitment accepting
         or providing for any Company Takeover Proposal; provided, however, that

         nothing in this Section 6.02 or elsewhere in this Agreement or in the
                         ------------
         Confidentiality Agreement (as defined in Section 9.01) shall prohibit

         under the Exchange Act with regard to a tender or exchange offer not
         made in violation of this Section 6.02; and provided, further, that
                                   ------------      --------  -------
         nothing in this Section 6.02 or elsewhere in this Agreement or in the
                         ------------
         Confidentiality Agreement shall prohibit Company, before the adoption
         of this Agreement by the stockholders of Company, from furnishing
         information regarding Company or entering into negotiations or
         discussions with, any person in response to a Company Takeover Proposal
         made, submitted or announced by such person (and not withdrawn) or,
         subject to the provisions of Section 6.05, endorsing and/or

         providing for, a Company Superior Offer (as defined in Section
                                                                -------
         6.05(b)), and any such actions enumerated in this proviso shall not be
         -------
         considered a breach of this Agreement if and to the extent that each of
         the following conditions is satisfied: (1) such Company Takeover
         Proposal is not attributable to a material breach by Company of this
         Section 6.02(a) or Section 6.05; (2) the Board of Directors of Company
         ---------------    -------------
         concludes in good faith, after consultation with its outside legal
         counsel, that failure to take such action would be inconsistent with
         the fiduciary obligations of the Board of Directors of Company to
         Company stockholders under applicable law; (3) prior to furnishing any
         such information to, or entering into discussions or negotiations with,
         such person, Company gives Parent written notice of the identity of
         such person, the terms and conditions of such Company Takeover Proposal
         and Company's intention to furnish information to, or enter into
         discussions or negotiations with, such person; (4) Company receives
         from such person an executed confidentiality agreement which shall not
         in any way restrict Company from complying with its disclosure
         obligations under this Agreement and which shall contain customary
         limitations on the use and disclosure of all nonpublic written and oral
         information furnished to such person by or on behalf of Company and
         other terms no less favorable to Company than those set forth in the
         Confidentiality Agreement; and (5) contemporaneously with furnishing
         any such information to such person, Company furnishes such information
         to Parent (to the extent that such information has not been previously
         furnished by Company to Parent).

                   (b) Company and its Representatives shall immediately cease
         and cause to be terminated any and all existing discussions,
         negotiations, exchanges of information and other activities with
         respect to any Company Takeover Proposal pending as of the date of this
         Agreement.  Promptly following the execution and delivery of this
         Agreement, Company shall (i) inform each of its directors and officers
         and financial, legal, accounting and other advisors retained or
         involved in the transactions contemplated by this Agreement of the
         obligations undertaken in this Section 6.02 and in the Confidentiality

         or offers constituting a Company Takeover Proposal are received by, any
         non-public information in connection with any Company Takeover Proposal
         is requested from, or any discussions or negotiations with respect to a
         Company Takeover Proposal are sought to be initiated or continued with,
         Company's officers or directors or other individuals involved on behalf
         of Company in the negotiation of the transactions contemplated by this
         Agreement, or, to the knowledge of the foregoing persons, any of

                   (c) Company and Parent agree that irreparable damage would
         occur in the event that the provisions of this Section 6.02 are not
                                                        ------------
         performed in accordance with their specific terms or were otherwise
         breached.  It is accordingly agreed by the parties hereto that Parent
         shall be entitled to seek an injunction or injunctions to prevent
         breaches of this Section 6.02 and to enforce specifically the terms and

requisite commercially reasonable efforts to continue the quotation of Company
Common Stock and Parent Common Stock, respectively, on the Nasdaq National

Unless otherwise required by law, the parties will hold any such information

          6.05  Stockholders Meetings.

                    (a)  Subject in each case to applicable laws, rules and
          regulations: (i) Company will take all action reasonably necessary in
          accordance with the DGCL and its Certificate of Incorporation and
          Bylaws and applicable Nasdaq Stock Market rules to cause the Company
          Stockholders Meeting to be held for the purpose of voting upon the
          adoption of this Agreement, and to cause a vote of the Company's
          stockholders on the adoption of this Agreement to be taken, in each
          case as promptly as practicable after the date hereof, and (ii)
          subject further to the provisions of Section 6.01(b), Parent will take
                                               ---------------
          all action reasonably necessary in accordance with the DGCL and its
          Certificate of Incorporation and Bylaws and applicable Nasdaq Stock
          Market rules to cause the Parent Stockholders Meeting to be held for
          the purpose of voting upon the Parent Voting Proposal, and to cause a

<PAGE>

          shall use their commercially reasonable efforts to hold such meetings
          at the same time and on the same day and as promptly as practicable
          after the date hereof. Parent and, subject to Company's right's under
          Section 8.01(h), Company shall solicit from their respective
          ---------------
          stockholders proxies in favor of the adoption of this Agreement (in
          the case of Company stockholders) and approval of the Parent Voting
          Proposal (in the case of Parent stockholders), and will take all other
          action necessary or advisable to secure the vote or consent of their
          respective stockholders required under NASD rules and the DGCL, as
          applicable; provided, however, that neither Company nor Parent shall
                      --------  -------
          be required to take any action that its respective Board of Directors
          determines in good faith after consultation with outside legal counsel
          would be inconsistent with its fiduciary duties to its stockholders
          under applicable law. Notwithstanding anything to the contrary
          contained in this Agreement, Company may adjourn or postpone the
          Company Stockholders Meeting, and Parent may adjourn or postpone the
          Parent Stockholders Meeting, to the extent that (x) such adjournment
          or postponement is necessary to ensure that any necessary supplement
          or amendment to the Joint Proxy Statement/Prospectus is provided to
          such party's stockholders in advance of the applicable vote or (y)
          additional time is reasonably required to solicit proxies in favor of
          the approvals required by Section 7.01(a) or (z) as of the time for
                                    ---------------
          which such stockholders meeting is originally scheduled (as set forth
          in the Joint Proxy Statement/Prospectus) there are insufficient shares
          represented (either in person or by proxy) to constitute a quorum
          necessary to conduct the business of such stockholders meeting.
          Company shall ensure that the Company Stockholders Meeting is called,
          noticed, convened, held and conducted, and that all proxies solicited
          by Company in connection with the Company Stockholders Meeting are
          solicited, and Parent shall ensure that Parent Stockholders Meeting is
          called, noticed, convened, held and conducted, and that all proxies
          solicited by Parent in connection with the Parent Stockholders Meeting
          are solicited, in compliance with the DGCL, applicable charter
          documents, Nasdaq Stock Market rules and all other applicable legal
          requirements.

          that Company's stockholders vote in favor of the adoption of this
          Agreement at the Company Stockholders Meeting; (ii) the Joint Proxy
          Statement/Prospectus shall include a statement to the effect that the
          Board of Directors of Company has recommended that Company
          stockholders vote in favor of the adoption of this Agreement at the
          Company Stockholders Meeting; and (iii) neither the Board of Directors
          of Company nor any committee thereof shall withdraw, amend or modify,
          or resolve to withdraw, amend or modify, in a manner adverse to
          Parent, the recommendation of the Board of Directors of Company that
          Company stockholders vote in favor of the adoption of this Agreement;
          provided, however, that nothing in this Agreement or in the
          --------  -------
          Confidentiality Agreement shall prevent the Board of Directors of
          Company from omitting such recommendation from the Joint Proxy
          Statement/Prospectus or from withholding, withdrawing, amending or
          modifying such recommendation if: (A) a Company Superior Offer is made
          and is not withdrawn, (B) such Company Superior Offer is not
          attributable to a breach by Company in any material respect of any of
          the restrictions set forth in Section
                                        -------

          ----
          to Parent of written notice advising Parent that the Board of
          Directors of Company intends to withhold, withdraw, amend or modify
          such recommendation, and (D) the Board of Directors of Company
          concludes in good faith, after consultation with its outside legal
          counsel, that inclusion of such recommendation, or the failure to
          withhold, withdraw, amend or modify such recommendation, would be
          inconsistent with the fiduciary duties of the Board of Directors of
          Company to Company stockholders under applicable law. For purposes of
          this Agreement,

          "Company Superior Offer" shall mean a bona fide written offer made by

          pursuant to which the stockholders of Company immediately preceding
          such transaction hold less than fifty percent (50%) of the equity
          interest in the surviving, resulting or acquiring entity of such
          transaction; (y) a sale or other disposition by Company of assets
          (excluding inventory and used equipment sold in the ordinary course of

          or an exchange offer or issuance by Company), directly or indirectly,
          of beneficial ownership or a right to acquire beneficial ownership of
          shares representing fifty percent (50%) or more of the voting power of
          the then outstanding shares of capital stock of Company, in each case
          on terms that, in the good faith judgment of the Board of Directors of
          Company (after consultation with an investment bank of nationally
          recognized reputation) are more favorable (in a manner that, in the
          totality of such terms, is not immaterial) to Company stockholders
          than the Merger (after taking into account all relevant factors,
          including any conditions to the Company Superior Offer, the timing of
          the consummation of the transaction pursuant to the Company Superior
          Offer, the risk of nonconsummation thereof and the need for any
          required governmental or other consents, filings and approvals);
          provided, however, that an offer shall only be a Company Superior
          --------  -------
          Offer if any financing required to consummate the transaction
          contemplated by such offer is committed or is otherwise reasonably
          likely, in the good faith judgment of Company's Board of Directors, to
          be obtained on a timely basis.

                    (c)  (i) The Board of Directors of Parent has recommended
          that Parent stockholders vote in favor of the Parent Voting Proposal
          at the Parent Stockholders Meeting; (ii) the Joint Proxy
          Statement/Prospectus shall include a statement to the effect that the
          Board of Directors of Parent has recommended that Parent stockholders
          vote in favor of the Parent Voting Proposal at the Parent Stockholders
          Meeting; and (iii) neither the Board of Directors of Parent nor any

          recommendation of the Board of Directors of Parent that Parent
          stockholders vote in favor of the Parent Voting Proposal. Parent, as
          the sole stockholder of Merger Sub, will vote its shares of Merger Sub
          voting stock in favor of adoption of this Agreement.

          applicable law. Company and Parent shall cooperate with each other in
          connection with the making of all such filings, including providing
          copies of all such filings to the non-filing party and its advisors
          prior to filing and, if requested, shall accept all reasonable
          additions, deletions or changes suggested in connection therewith.
          Company and Parent shall use commercially reasonable efforts to

          transactions contemplated by this Agreement, including by vigorously
          pursuing all available avenues of administrative and judicial appeal
          and all available legislative action. The parties hereto will consult
          and cooperate with one another, and consider in good faith the views
          of one another, in connection with any analyses, appearances,

          federal, state or foreign antitrust or fair trade law. Subject to the
          requirements of applicable law, Parent shall be entitled to direct any
          proceedings or negotiations with any Governmental Entity relating to
          any such analyses, appearances, presentations, memoranda, briefs,

                                            --------
          Company a reasonable opportunity to participate therein.
          Notwithstanding anything to the contrary in this Section 6.06, neither

          Parent nor Company nor any of their respective Subsidiaries shall be
          required to sell or otherwise dispose of, or hold separate (through
          the establishment of a trust or otherwise), any assets or categories
          of assets, or businesses of Parent, Company or any of their
          affiliates, or to withdraw from doing business in a particular
          jurisdiction or to take any other action that would, in any case,
          reasonably be expected to have a Parent Material Adverse Effect or a
          Company Material Adverse Effect.

                    (c)  Each of Company and Parent shall give (or shall cause
          their respective Subsidiaries to give) any notices to third parties,
          and use, and cause their respective Subsidiaries to use, commercially
          reasonable efforts to obtain any third party consents related to or

          Effect from occurring.

          6.07  Public Disclosure. Parent and Company shall consult with each
other before issuing any press release or otherwise making any public statement
with respect to the Merger or this Agreement and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by law.

          6.08  Tax-Free Reorganization. At or prior to the filing of the
Registration Statement, Company and Parent shall execute and deliver to Cooley

representation letters pursuant to the first sentence of this Section 6.08, each

          6.09  Stock Plans.

                    (a)  Company has provided Parent with a true and complete
          list as of March 9, 2000 of all holders of outstanding options under
          the Company Stock Plans, including the number of shares of Company
          Common Stock subject to each such option, the exercise or vesting
          schedule, the exercise price and term of each such option (in each
          case, without giving effect to the 100% stock dividend being
          distributed by Company on or about March 13, 2000. On the Closing
          Date, Company shall deliver to Parent an updated list current as of
          such Closing Date. At the Effective Time, each outstanding option to
          purchase shares of Company Common Stock (a "Company Stock Option")
                                                      --------------------
          under the Company Stock Plans, whether vested or unvested, shall be
          assumed and shall constitute an option to acquire, on the same terms
          and conditions as were applicable under such Company Stock Option, the
          same number of shares of Parent Common Stock as the holder of such
          Company Stock Option would have been entitled to receive pursuant to
          the Merger had such holder exercised such option (including any
          unvested portion thereof) in full (disregarding any limitation on
          exercisability thereof) immediately prior to the Effective Time
          (rounded downward to the nearest whole number), at a price per share
          (rounded upward to the nearest whole cent) equal to (y) the aggregate
          exercise price for the shares of Company Common Stock purchasable
          pursuant to such Company Stock Option immediately prior to the
          Effective Time divided by (z) the number of full shares of Parent
          Common Stock deemed purchasable pursuant to such Company Stock Option
          in accordance with the foregoing. All outstanding rights of Company
          that it may hold immediately prior to the Effective Time to repurchase
          unvested shares of Company Common Stock issued or issuable under any
          of the Company Stock Plans (the "Repurchase Options") shall be
                                           ------------------
          assigned to Parent and shall thereafter be exercisable by Parent upon
          the same terms and conditions in effect immediately prior to the
          Effective Time, except that the shares purchasable pursuant to the
          Repurchase Options and the purchase price per shall be adjusted to
          reflect the Exchange Ratio.

                    (b)  Except as otherwise provided in the Company Stock
          Plans, the documents governing the outstanding Company Stock Options
          under the Company Stock Plans, and offer letters and other agreements
          affecting such Company Stock Options, the Merger shall not result in
          the termination or acceleration of any outstanding Company Stock
          Options under the Company Stock Plans that are so assumed by Parent.
          It is the intention of the parties that the Company Stock Options so
          assumed by Parent qualify following the Effective Time as incentive
          stock options as defined in Section 422 of the Internal Revenue Code
          to the extent such Company Stock Options qualified as incentive stock
          options prior to the Effective Time. As promptly as reasonably
          practicable and in any event within thirty (30) business days after
          receipt of all option documentation it requires relating to the
          outstanding Company Stock Options, Parent will issue to

                                      40
<PAGE>

          each person who, immediately prior to the Effective Time, is a holder
          of an outstanding Company Stock Option under the Company Stock Plans
          that is to be assumed by Parent hereunder, a document evidencing the
          foregoing assumption of such Company Stock Option by Parent.

                    (c)  Parent shall take all corporate action necessary to
          reserve for issuance a sufficient number of shares of Parent Common
          Stock for delivery under Company Stock Options assumed in accordance
          with this Section 6.09. As promptly as reasonably practicable and in
                    ------------
          any event within fifteen (15) business days after receipt of all
          option documentation it requires relating to the outstanding Company
          Stock Options, Parent shall file a registration statement on Form S-8
          (or any successor form) covering shares of Parent Common Stock
          issuable pursuant to such Company Stock Options assumed by Parent
          provided that such Company Stock Options qualify for registration on
          such Form S-8 (or any such successor form). Company shall cooperate
          with and assist Parent in the preparation of such registration
          statements.

                    (d)  The Board of Directors of Company shall, prior to or as
          of the Effective Time, take all necessary actions, pursuant to and in
          accordance with the terms of the Company Stock Plans and the
          instruments evidencing the Company Stock Options, to provide for the
          conversion of the Company Stock Options into options to acquire Parent
          Common Stock in accordance with this Section 6.09, and to provide that
                                               ------------
          no consent of the holders of the Company Stock Options is required in
          connection with such conversion.

                    (e)  Assuming that the Company delivers to Parent the
          Section 16 Information (as defined below) in a timely fashion, the
          Board of Directors of Parent, or a committee of two or more "non-
                                                                       ----

          action such that, the deemed grant to Company Insiders (as defined
          below) of options to purchase Parent Common Stock under the Company
          Stock Options (as converted into options to acquire Parent Common
          Stock pursuant to this Section 6.09), and the receipt by Company
                                 ------------
          Insiders of Parent Common Stock in exchange for Company Common Stock
          pursuant to the Merger, are intended to be exempt from liability
          pursuant to Section 16(b) of the Exchange Act. Such resolutions shall
          comply with the approval conditions of Rule 16b-3 under the Exchange
          Act for purposes of such Section 16(b) exemption, including specifying
          the name of each Company Insider, the number of equity securities to
          be acquired or disposed of by each Company Insider, the material terms
          of any derivative securities, and that the approval is intended to
          make the receipt of such securities exempt pursuant to Rule 16b-3(d)
          under the Exchange Act. "Section 16 Information" shall mean the names
                                   ----------------------

          held by each Company Insider and expected to be exchanged for Parent
          Common Stock in the Merger and the number and a description of Company
          Stock Options held by each Company Insider and expected to be
          converted into options to acquire Parent Common Stock in

          requirements of Section 16(b) of the Exchange Act with respect to
          Parent and whose names are included in the Section 16 Information.

                    (f)  At the Effective Time, Parent shall assume, with
          respect to each Company employee who agrees to waive the exercise of
          any Purchase Right (as defined in the Company ESPP) on any Purchase
          Date (as defined in the Company ESPP) after February 15, 2001, the
          Company ESPP and all Purchase Rights held by employees of Company or
          any of its Subsidiaries who are participating in the Company ESPP, and
          Parent shall continue the assumed Company ESPP and the related
          offering and purchase periods thereunder (for the benefit of all
          persons who are employees of Company or any of its Subsidiaries as of
          the Closing and who have waived any Purchase Rights on any Purchase
          Date after February 15, 2001); provided, however, that: (i) each such

          15, 2001 and the percentage of compensation to be deducted for each
          such holder. As promptly as reasonably practicable and in any event
          within fifteen (15) business days after receipt of all Company ESPP
          documentation it requires relating to outstanding assumed Purchase
          Rights, Parent shall file with the SEC a registration statement on
          Form S-8 relating to the shares of Parent Common Stock issuable
          pursuant to Purchase Rights exercised under the assumed Company ESPP.

                    (g)  Company shall take, or cause to be taken, all action
          necessary to provide that no additional Offering Periods under the
          Company ESPP shall commence after the date of this Agreement, other

          (and Parent and the Surviving Corporation shall also advance expenses
          as incurred to the fullest extent permitted under applicable law,

          provides an undertaking to repay such advances if it is ultimately
          determined that such Indemnified Party is not entitled to

          coverage in amount and scope at least as favorable as the coverage
          currently planned by Company and described on Schedule 6.11(b);

          Corporation be required to expend for any given year for such coverage
          in excess of one hundred fifty percent (150%) of the annual premium
          quoted to Company for such coverage as disclosed by Company to Parent
          on Schedule 6.11(b) (the "Current Premium"); and if the annual premium

          for such coverage would at any time exceed one hundred fifty percent

          maintain insurance policies which provide the maximum and best
          coverage available at an annual premium equal to one hundred fifty
          percent (150%) of the Current Premium.

                    (c)  Without limiting any of the rights of any of the

                                                                        -------
          6.11, for a period of six years after the Effective Time, to the
          ----
          extent there is any claim, action, suit, proceeding or investigation
          (whether arising before or after the Effective Time) against or
          involving any Indemnified Party that arises out of or pertains to any
          action or omission (or alleged action or omission) in his or her
          capacity as a director, officer, employee, principal stockholder,

          incurred the reasonable fees and expenses of such counsel, promptly
          after statements therefor are received, and (iii) the Surviving
          Corporation and Parent will cooperate in the defense of any such
          matter; provided, however, that neither the Surviving Corporation nor
                  --------  -------
          Parent shall be liable for any settlement effected without its written
          consent (which consent shall not be unreasonably withheld, conditioned
          or delayed); and provided, further, that, in the event that any claim
                           --------  -------
          or claims for indemnification are asserted or made within such six-
          year period, all rights to indemnification in respect to any such
          claim or claims shall continue until the final disposition of any and
          all such claims. The Indemnified Parties as a group may retain only
          one law firm to represent them with respect to any single action
          unless such law firm determines that there is, under applicable
          standards of professional conduct, a material risk of conflict on any
          significant issue between the positions of any two or more Indemnified
          Parties.

                    (d)  Parent and the Surviving Corporation jointly and
          severally agree to pay all expenses, including reasonable attorneys'
          fees, that may be incurred by any Indemnified Party in enforcing the
          indemnity and other obligations provided for in this Section 6.11 to

          indemnification under this Section 6.11.

                    (e)  The provisions of this Section 6.11 are intended to be
                                                ------------
          in addition to the rights otherwise available to the Indemnified
          Parties by law, charter, statute, bylaw or agreement, and shall
          operate for the benefit of, and shall be enforceable by, each of the
          Indemnified Parties, and their heirs, representatives, successors and
          assigns.

          6.12  Benefit Plans.

                    (a)  Parent agrees that, during the period commencing at the
          Effective Time and continuing for a reasonable period thereafter, the
          employees of Company and its Subsidiaries will continue to be provided
          with benefits under employee benefit plans (other than stock option or
          other plans involving the potential issuance of securities) which on
          average are substantially as favorable in the aggregate as those
          currently provided by Company and its Subsidiaries to such employees
          (except with respect to the 401(k) plan as provided below).

                    (b)  Unless Parent consents otherwise in writing, Company
          shall take all action necessary to terminate, or cause to be
          terminated, before the Effective Time, any Company Employee Plan that
          is a 401(k) plan or other defined contribution retirement plan. Parent
          shall permit the rollover of the accounts of participants in the
          Company 401(k) plans to the Parent 401(k) plan (including outstanding
          loans of those participants who became employees of Parent or any of
          its Subsidiaries, or who remain employees of the Surviving Corporation
          or any of its Subsidiaries).

                    (c)  Upon the termination of the Company welfare plans,
          Parent shall include Company employees in Parent's welfare plans
          (within the meaning of Section 3(1) of ERISA) and fringe benefit plans
          on the same basis and terms as similarly situated Parent employees
          currently participate. All welfare benefit plans of Parent or the
          Surviving Corporation in which employees of Company or any of its
          Subsidiaries participate after the Effective Time shall (i) recognize
          expenses and claims that were incurred by such employees in the year
          in which the Effective Time occurs toward applicable co-payments, out
          of pocket maximums and deductibles, and (ii) provide coverage for
          preexisting health conditions to the extent covered under the
          applicable plans or programs of Company or any of its Subsidiaries as
          of the Effective Time. In addition, for eligibility purposes
          (including waiting period and evidence of insurability), under plans
          of the Surviving Corporation or Parent, service by an employee for
          Company or any of its Subsidiaries and any predecessor prior to the
          Effective Time shall be taken into account to the same extent as
          service for Parent; provided, however, that nothing herein shall
                              --------  -------
          require the inclusion of any such employee in any such plan prior to
          the Effective Time, and provided further, that in determining the
                                  ----------------
          amount of vacation pay owed to any such employee from and after the
          Effective Time under the applicable terms of the vacation pay plan of
          the Surviving Corporation or Parent (which terms need not be
          comparable to the terms of the vacation plan or policy of Company or
          any of its Subsidiaries and any predecessor, corporation or entity),
          credit shall be given for such employee's

                                      45

          service for Company or any of its Subsidiaries and any predecessor,
          corporation or entity prior to the Effective Time. Without limiting
          the effect of Section 6.09(f), employees of Company or any of its
                        ---------------
          Subsidiaries and any predecessor corporation or entity as of the
          Effective Time shall be permitted to participate in Parent's Employee
          Stock Purchase Plan (the "Parent ESPP") commencing on the first
                                    -----------
          enrollment date following the Effective Time, subject to compliance
          with the eligibility provisions of such plan (with employees receiving
          credit, for purposes of such eligibility provisions, for service with
          Company or any of its subsidiaries and any predecessor corporation or
          entity.

                    (d)  With respect to each benefit plan, program, practice,
          policy or arrangement maintained by Parent (the "Parent Employee
                                                           ---------------
          Plans") in which employees of Company or its Subsidiaries subsequently
          -----
          participate, Parent will recognize such employee's cumulative prior
          service to Company and its Subsidiaries (and any predecessor
          corporation or entity) for purposes of determining eligibility to
          participate in and for the vesting of benefits under such Parent
          Employee Plans to the same extent as service for Parent; provided,
                                                                   --------
          that such recognition shall not be for the purpose of determining
          retirement benefits and accrual. Notwithstanding the foregoing, for a
          period of no less than one year after the Effective Time, Parent shall
          provide severance and termination benefits (other than acceleration of
          option vesting) to employees of Company and its Subsidiaries that are
          no less favorable than those provided by Company or its Subsidiaries
          to such Company employees as of the date hereof.

          6.13  Registration Statement; Joint Proxy Statement/Prospectus.  If at
any time prior to the Effective Time any event relating to Company or any of its
Affiliates, officers or directors should be discovered by Company which should
be set forth in an amendment to the Registration Statement or a supplement to
the Joint Proxy Statement/Prospectus, Company shall promptly inform Parent. If
at any time prior to the Effective Time any event relating to Parent or any of
its Affiliates, officers or directors should be discovered by Parent which
should be set forth in an amendment to the Registration Statement or a
supplement to the Joint Proxy Statement/Prospectus, Parent shall promptly inform

the Exchange Act) with respect to an Opposing Proposal, (ii) initiate a
stockholders' vote with respect to an Opposing Proposal or (iii) become a member
of a "group" (as such term is used in Section 13(d) of the Exchange Act) with

respect to any voting securities of Company with respect to an Opposing
Proposal.

          2.3  Notwithstanding the foregoing, nothing in this Agreement shall
limit or restrict Stockholder from (i) acting in his capacity as a director or
officer of Company, to the extent applicable, it being understood that this
Agreement shall apply to Stockholder solely in his capacity as a stockholder of
Company or (ii) voting in his sole discretion on any matter other than those
matters referred to in Section 2(a).

          3.   Irrevocable Proxy.

          Stockholder hereby agrees to timely deliver to Parent a duly executed
proxy in the form attached hereto as Annex A (the "Proxy"), such Proxy to cover
the issued and outstanding Shares and all issued and outstanding New Shares in
respect of which Stockholder is the record holder and is entitled to vote at
each meeting of the stockholders of Company (including, without limitation, each
written consent in lieu of a meeting) prior to the Expiration Date. In the event
that Stockholder is unable to provide any such Proxy in a timely manner,
Stockholder hereby grants Parent a power of attorney to execute and deliver such
Proxy for and on behalf of Stockholder, such power of attorney, which being
coupled with an interest, shall survive any death, disability, bankruptcy, or
any other such impediment of Stockholder. Upon the execution of this Agreement
by Stockholder, Stockholder hereby revokes any and all prior proxies or powers
of attorney given by Stockholder with respect to voting of the Shares on the
matters referred to in Section 2(a) and agrees not to grant any subsequent
proxies or powers of attorney with respect to the voting of the Shares on the
matters referred to in Section 2(a) until after the Expiration Date.

          4.   Representations, Warranties and Covenants of Stockholder.

          Stockholder hereby represents, warrants and covenants to Parent as
follows:

          4.1  Stockholder has full power and legal capacity to execute and
deliver this Agreement and to perform his obligations hereunder. This Agreement
has been duly and validly executed and delivered by Stockholder and constitutes
the valid and binding obligation of Stockholder, enforceable against Stockholder
in accordance with its terms, except as may be limited by (i) the effect of
bankruptcy, insolvency, conservatorship, arrangement, moratorium or other laws
affecting or relating to the rights of creditors generally, or (ii) the rules
governing the availability of specific performance, injunctive relief or other
equitable remedies and general principles of equity, regardless of whether
considered in a proceeding in equity or at law. The execution and delivery of
this Agreement by Stockholder does not, and the performance of Stockholder's
obligations hereunder will not, result in any breach of or constitute a default
(or an event that with notice or lapse of time or both would become a default)
under, or give to others any right to terminate, amend, accelerate or cancel any
right or obligation under, or result in the creation of any lien or encumbrance
on any Shares or New Shares pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or

                                      3.

obligation to which Stockholder is a party or by which Stockholder or the Shares
or New Shares are or will be bound or affected.

          4.2  Stockholder has read Section 6.02 of the Merger Agreement and
understands the Company's restrictions thereunder.

          4.3  Stockholder understands and agrees that if Stockholder attempts
to transfer, vote or provide any other person with the authority to vote any of
the Shares other than in compliance with this Agreement, Company shall not, and
Stockholder hereby unconditionally and irrevocably instructs Company to not,
permit any such transfer on its books and records, issue a new certificate
representing any of the Shares or record such vote unless and until Stockholder
shall have complied with the terms of this Agreement.

          5.   Additional Documents.

          Stockholder hereby covenants and agrees to execute and deliver any
additional documents necessary or desirable, in the reasonable opinion of
Parent, to carry out the purpose and intent of this Agreement.

          6.   Consent and Waiver.

          Stockholder hereby gives any consents or waivers that are reasonably
required for the consummation of the Transaction under the terms of any
agreement to which Stockholder is a party or pursuant to any rights Stockholder
may have provided, however, that Stockholder shall not be required by this
Section 6 to give any consent or waiver in his capacity as a director or officer
of Company.

          7.   Termination.

          This Agreement and the Proxy delivered in connection herewith and all
obligations of Stockholder hereunder and thereunder, shall terminate and shall
have no further force or effect as of the Expiration Date.

          8.   Miscellaneous.

          8.1  Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid, void
or unenforceable, then the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

          8.2  Binding Effect and Assignment. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the
rights, interests or obligations of the parties hereto may be assigned by either
of the parties without the prior written consent of the other. This Agreement is
intended to bind Stockholder solely as a securityholder of Company only with
respect to the specific matters set forth herein.

acknowledge that Parent will be irreparably harmed and that there will be no

other remedies that may be available to Parent upon any such violation, Parent
shall have the right to enforce such covenants and agreements by specific
performance, injunctive relief or by any other means available to Parent at law
or in equity and Stockholder hereby waives any and all defenses which could
exist in its favor in connection with such enforcement and waives any
requirement for the security or posting of any bond in connection with such
enforcement.

          The undersigned stockholder of Aspect Development, Inc., a Delaware
corporation ("Company"), hereby irrevocably appoints the members of the Board of
Directors of i2 Technologies, Inc., a Delaware corporation ("Parent"), and each
of them, or any other designee of Parent, as the sole and exclusive attorneys
and proxies of the undersigned, with full power of substitution and
resubstitution, to vote and exercise all voting rights (to the full extent that
the undersigned is entitled to do so) with respect to all of the issued and
outstanding shares of capital stock of Company that now are owned of record by
the undersigned, (collectively, the "Shares") in accordance with the terms of
this Irrevocable Proxy. The Shares beneficially owned by the undersigned
stockholder of Company as of the date of this Irrevocable Proxy are listed on

exercise all voting rights of the undersigned with respect to the Shares
(including, without limitation, the power to execute and deliver written
consents), at every annual, special or adjourned meeting of the stockholders of
Company and in every written consent in lieu of such meeting:

          (a)  in favor of adoption of the Merger Agreement and any proposal or
action which would, or could reasonably be expected to, facilitate the Merger;

          (b)  against approval of any proposal made in opposition to or

          (c)  against any Company Takeover Proposal (as defined in the Merger
Agreement) with any party other than Parent or an affiliate of Parent as
contemplated by the Merger Agreement;

          (d)  against any liquidation or winding up of Company; and

          (e)  against any other proposal or action which would, or could
reasonably be expected to impede, frustrate, prevent, prohibit or discourage the
Merger.

          The attorneys and proxies named above may not exercise this
Irrevocable Proxy on any other matter except as provided above. The undersigned
stockholder may vote the Shares on all other matters.

          All authority herein conferred shall survive the death or incapacity
of the undersigned and any obligation of the undersigned hereunder shall be
binding upon the heirs, personal representatives, successors and assigns of the
undersigned.
