Officer ("CEO") both upon initial hire and as may be reasonably assigned from
time to time. Executive shall perform faithfully and diligently all duties

Company, as well as all applicable federal, state and local laws, regulations or
ordinances. Executive will act solely on behalf of Company at all times.

performance of Executive's assigned duties for Company, unless Executive

the size, type and quality as provided to Executive prior to the Effective Date)
as shall be suitable to the character of Executive's position with Company and
adequate for the performance of Executive's duties hereunder.

         6.       Business Expenses. Executive will be reimbursed for all

                  7.1      Termination for Cause by Company. Company may

and the Executive; (iii) any amounts to which Executive is entitled pursuant to
Section 5 or 6 hereof; and (iv) any benefit or right to which Executive is

connection with the grant of Options to Executive (the "SEVERANCE Payments"),
provided that Executive: (a) complies with all surviving provisions of this
Agreement, including without limitation those provisions specified in Section
14.8, below; and (b) executes a full general release, releasing all claims,
known or unknown, that Executive may have against Company arising out of or any
way related to Executive's employment or termination of employment with Company,
in substantially the form attached hereto as Exhibit B, or in another form that
is acceptable to Company in its sole discretion. All other Company obligations
to Executive will be automatically terminated and completely extinguished upon
termination of employment.

                  7.3      Termination for Good Reason by Executive/Severance.
Executive may terminate Executive's employment under this Agreement for Good
Reason (defined below) at any time on five (5) days' advance written notice to
Company. In the event of such termination,

                                       3
<PAGE>

Executive will be entitled to receive the Severance Payments described in
Section 7.2, above, provided that Executive complies with the conditions to
receiving the Severance Payments described in Sections 7.2(a) and 7.2(b), above.

         For purposes of this Agreement, "GOOD REASON" is defined as the
occurrence of any of the following conditions:

                           (i)      a failure to pay, or any reduction of
Executive's Base Salary as in effect immediately prior to the Change of Control
(as defined in Section 7.5(b)(iv)) or Executive's Bonus in effect prior to the
Change of Control (subject to applicable performance requirements with respect
to the actual amount of Bonus earned by Executive); or

                           (ii)     any material breach of this Agreement by
Company that is not cured within thirty (30) days after Company's receipt of
written notice from Executive specifying the material breach of this Agreement.

                  7.4      Voluntary Resignation by Executive. Executive may
voluntarily resign Executive's position with Company for any reason, at any time
after the Effective Date, on five (5) days' advance written notice. In the event
of Executive's resignation, Executive will be entitled to receive only the Base
Salary for the five-day notice period and no other amount for the remaining
months of the current term, whether the Initial Term or a subsequent one-year
term (other than amounts to which Executive is entitled pursuant to Sections 5
or 6 hereof). Executive shall be entitled to any benefit or right to which
Executive is entitled pursuant to the Plan, however, there shall be not
additional vesting under Executive's Option. All other Company obligations to
Executive pursuant to this Agreement will become automatically terminated and
completely extinguished upon termination of employment. In addition, Executive
will not be entitled to receive any Severance Payments described in Section 7.2,
above. The provisions of this Section 7.4 shall not apply to Executive's
resignation for Good Reason.

                  7.5      Federal Excise Tax Under Section 4999 of the Code.

                  (a)      Additional Payment. In the event that any payment or
benefit received or to be received by Executive pursuant to this Agreement or
otherwise payable to Executive (collectively, the "PAYMENTS") would be subject
to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986,
as amended (the "CODE"), or any similar or successor provision (the "EXCISE
TAX"), Company shall pay to Executive within ninety (90) days of the date
Executive becomes subject to the Excise Tax, an additional amount (the "GROSS-UP
PAYMENT") such that the net amount retained by Executive from the Payments and
the Gross-Up Payment, after deduction of (1) any Excise Tax on the Payments and
(2) any federal, state and local income or employment tax and Excise Tax upon
the payment provided for by this Section, shall be equal to the Payments.

                  (b)      Determination of Excise Tax. For purposes of
determining whether any of the Payments will be subject to the Excise Tax and
the amount of such Excise Tax:

                                    (i)      Any payments or benefits received
or to be received by Executive in connection with transactions contemplated by a
Change of Control (as defined below) event or Executive's termination of
employment (whether pursuant to the terms of this Agreement or any other plan,
arrangement or agreement with Company), shall be treated as

                                       4
<PAGE>

"parachute payments" within the meaning of Section 280G of the Code or any
similar or successor provision, and all "excess parachute payments" within the
meaning of Section 280G of the Code or any similar or successor provision shall
be treated as subject to the Excise Tax, unless in the opinion of tax counsel
("TAX Counsel") selected by Company and reasonably acceptable to Executive such
payments or benefits (in whole or in part) do not constitute parachute payments,
or such excess parachute payments (in whole or in part) represent reasonable
compensation for services actually rendered within the meaning of Section 280G
of the Code (or any similar or successor provision of the Code) in excess of the
base amount within the meaning of Section 280G of the Code (or any similar or
successor provision of the Code), or are otherwise not subject to the Excise
Tax.

                                    (ii)     The amount of the Payments which
shall be treated as subject to the Excise Tax shall be equal to the lesser of
(i) the total amount of the Payments or (ii) the amount of the excess parachute
payments within the meaning of Section 280G of the Code (after applying
paragraph (b)(1) above).

                                    (iii)    The value of any non-cash benefits
or any deferred payment or benefit shall be determined by Tax Counsel in
accordance with the principles of Section 280G of the Code.

                                    (iv)     Change of Control. A "CHANGE OF
CONTROL" is defined as any one of the following occurrences:

                                             a) Any "person" (as such term is
used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the
"EXCHANGE ACT")), other than a trustee or other fiduciary holding securities of
Company under an employee benefit plan of Company, becomes the "beneficial
owner" (as defined in Rule 13d-3 promulgated under the Exchange Act), directly
or indirectly, of the securities of Company representing 50% or more of (A) the
outstanding shares of common stock of Company or (B) the combined voting power
of Company's then-outstanding securities; or

                                             b) the sale or disposition of all
or substantially all of Company's assets (or any transaction having similar
effect is consummated); or

                                             c) Company is party to a merger or
consolidation that results in the holders of voting securities of Company
outstanding immediately prior thereto failing to continue to represent (either
by remaining outstanding or by being converted into voting securities of the
surviving entity) at least 50% of the combined voting power of the voting
securities of Company or such surviving entity outstanding immediately after
such merger or consolidation; or

                                             d) a liquidation or dissolution of
Company.

                  (c)      Determination of Gross-Up Payment. For purposes of
determining the amount of the Gross-Up Payment, Executive shall be deemed to pay
federal income taxes at the highest marginal rate of federal income taxation in
the calendar year in which the Gross-Up Payment is to be made and state and
local income taxes at the highest marginal rate of taxation in the state and
locality of Executive's residence on the date the Gross-Up Payment is to be
made, net of the maximum reduction in federal income taxes which could be
obtained from deduction of such state and local taxes.

                                       5
<PAGE>

                  (d)      Adjustments.

                                    (i)      In the event that the Excise Tax is
subsequently determined to be less than the amount taken into account hereunder,
Executive shall repay to Company at the time that the amount of such reduction
in Excise Tax is finally determined the portion of the Gross-Up Payment
attributable to such reduction (plus the portion of the Gross-Up Payment
attributable to the Excise Tax and federal, state and local income and
employment taxes imposed on the Gross-Up Payment being repaid by Executive if
such repayment results in a reduction in Excise Tax and/or a federal, state or
local income or employment tax deduction) plus interest on the amount of such
repayment at the rate provided in Section 1274(b)(2)(B) of the Code.

                                    (ii)     In the event that the Excise Tax is
determined to exceed the amount taken into account hereunder (including by
reason of any payment the existence or amount of which cannot be determined at
the time of the Gross-Up Payment), Company shall make an additional gross-up
payment in respect of such excess (plus any interest payable with respect to
such excess) at the time that the amount of such excess is finally determined.

                  7.6      Termination of Employment Upon Nonrenewal. In the
event either party decides not to renew this Agreement for a subsequent one-year
term in accordance with Section 3.2 above, the Agreement will expire,
Executive's employment with Company will terminate and Executive will only be
entitled to (i) Executive's Base Salary paid through the last day of the
then-current term; (ii) any amounts to which Executive is entitled pursuant to
Section 5 or 6 hereof; and (iii) any benefit or right to which Executive is
entitled pursuant to the Plan and Option Agreements delivered to Executive in
connection with the grant of Options to Executive. All other Company obligations
to Executive pursuant to this Agreement will become automatically terminated and
completely extinguished. In addition, Executive will not be entitled to any
Severance Payments described in Section 7.2.

         8.       No Conflict of Interest. During the term of Executive's
employment with Company, Executive must not engage in any work, paid or unpaid,
that creates an actual or potential conflict of interest with Company. If the
Board reasonably believes such a conflict exists during the term of this
Agreement, the Board may ask Executive to choose to discontinue the other work
or resign employment with Company.

         9.       Post-Termination Non-Competition.

                  9.1      Consideration For Promise To Refrain From Competing.
Executive agrees that Executive's services are special and unique, that
Company's disclosure of confidential, proprietary information and specialized
training and knowledge to Executive, and that Executive's level of compensation
and benefits are partly in consideration of and conditioned upon Executive not
competing with Company. Executive acknowledges that such consideration is
adequate for Executive's promises contained within this Section 9.

                  9.2      Promise To Refrain From Competing. Executive
understands Company's need for Executive's promise not to compete with Company
is based on the following: (a) Company has expended, and will continue to
expend, substantial time, money and effort in developing its proprietary
information; (b) Executive will in the course of Executive's employment develop,
be personally entrusted with and exposed to Company's proprietary information;
(c) both during and after the term of Executive's employment, Company will be
engaged in the highly competitive retail demand chain software industry; (d)
Company provides

                                       6
<PAGE>

products and services nationally and internationally; and (e) Company will
suffer great loss and irreparable harm if Executive were to enter into
competition with Company. Therefore, in exchange for the consideration described
in Section 9.1 above, Executive agrees that for the period of nine (9) months
following the date Executive ceases to render services to Company (the "COVENANT
PERIOD"), Executive will not either directly or indirectly, whether as an owner,
director, officer, manager, consultant, agent or employee: (i) work for a
competitor of Company, which is defined to include those entities or persons in
the business of developing, marketing, selling and supporting software designed
for businesses in the retail and consumer packaged goods markets or in the
business of helping companies synchronize their inventory decisions with
advanced supply chain, inventory management and data mining solutions, in any
country in which Company does business (the "RESTRICTED BUSINESS"); or (ii) make
or hold during the Covenant Period any investment in any Restricted Business,
whether such investment be by way of loan, purchase of stock or otherwise,
provided that there shall be excluded from the foregoing the ownership of not
more than 1% of the listed or traded stock of any publicly held corporation. For
purposes of this Section 9, the term "COMPANY" shall mean and include Company,
any subsidiary or affiliate of Company, any successor to the business of Company
(by merger, consolidation, sale of assets or stock or otherwise) and any other
corporation or entity of which Executive may serve as a director, officer or
employee at the request of Company or any successor of Company.

                  9.3      Reasonableness of Restrictions. Executive represents
and agrees that the restrictions on competition, as to time, geographic area,
and scope of activity, required by this Section 9 are reasonable, do not impose
a greater restraint than is necessary to protect the goodwill and business
interests of Company, and are not unduly burdensome to Executive. Executive
expressly acknowledges that Company competes on an international basis and that
the geographical scope of these limitations is reasonable and necessary for the
protection of Company's trade secrets and other confidential and proprietary
information. Executive further agrees that these restrictions allow Executive an
adequate number and variety of employment alternatives, based on Executive's
varied skills and abilities. Executive represents that Executive is willing and
able to compete in other employment not prohibited by this Agreement.

                  9.4      Reformation if Necessary. In the event a court of
competent jurisdiction determines that the geographic area, duration, or scope
of activity of any restriction under this Section 9 and its subsections is
unenforceable, the restrictions under this section and its subsections shall not
be terminated but shall be reformed and modified to the extent required to
render them valid and enforceable. Executive further agrees that the court may
reform this Agreement to extend the Covenant Period by an amount of time equal
to any period in which Executive is in breach of this covenant.

         10.      Confidentiality and Proprietary Rights. Executive agrees to
read, sign and abide by Company's Employee Innovations and Proprietary Rights
Assignment Agreement, which was previously executed by Executive and
incorporated herein by reference.

         11.      Nonsolicitation.

                  11.1     Nonsolicitation of Customers or Prospects. Executive
acknowledges that information about Company's customers is confidential and
constitutes trade secrets. Accordingly, Executive agrees that during the term of
this Agreement and for a period of nine (9) months after the termination of this
Agreement, Executive will not, either directly or indirectly, separately or in
association with others, interfere with, impair, disrupt or damage Company's
relationship with any of its customers or customer prospects by soliciting or

                                       7
<PAGE>

encouraging others to solicit any of them for the purpose of diverting or taking
away business from Company.

                  11.2     Nonsolicitation of Company's Employees. Executive
agrees that during the term of this Agreement and for a period of nine (9)
months after the termination of this Agreement, Executive will not, either
directly or indirectly, separately or in association with others, interfere
with, impair, disrupt or damage Company's business by soliciting, encouraging,
hiring or attempting to hire any of Company's employees or causing others to
solicit or encourage any of Company's employees to discontinue their employment
with Company.

         12.      Injunctive Relief. Executive acknowledges that Executive's
breach of the covenants contained in Sections 9-11 (collectively "COVENANTS")
would cause irreparable injury to Company and agrees that in the event of any
such breach, Company shall be entitled to seek temporary, preliminary and
permanent injunctive relief without the necessity of proving actual damages or
posting any bond or other security.

         13.      Agreement to Arbitrate. To the fullest extent permitted by
law, Executive and Company agree to arbitrate any controversy, claim or dispute
between them arising out of or in any way related to this Agreement, the
employment relationship between Company and Executive and any disputes upon
termination of employment, including but not limited to breach of contract,
tort, discrimination, harassment, wrongful termination, demotion, discipline,
failure to accommodate, family and medical leave, compensation or benefits
claims, constitutional claims; and any claims for violation of any local, state
or federal law, statute, regulation or ordinance or common law. Claims for
breach of Company's Employee Innovations and Proprietary Rights Agreement,
workers' compensation, unemployment insurance benefits and Company's right to
obtain injunctive relief pursuant to Section 12 above are excluded. For the
purpose of this agreement to arbitrate, references to "Company" include all
parent, subsidiary or related entities and their employees, supervisors,
officers, directors, agents, pension or benefit plans, pension or benefit plan
sponsors, fiduciaries, administrators, affiliates and all successors and assigns
of any of them, and this Agreement shall apply to them to the extent Executive's
claims arise out of or relate to their actions on behalf of Company.

                  13.1     Initiation of Arbitration. Either party may exercise
the right to arbitrate by providing the other party with written notice of any
and all claims forming the basis of such right in sufficient detail to inform
the other party of the substance of such claims. In no event shall the request
for arbitration be made after the date when institution of legal or equitable
proceedings based on such claims would be barred by the applicable statute of
limitations.

                  13.2     Arbitration Procedure. The arbitration will be
conducted in Maricopa county, Arizona, by a single neutral arbitrator and in
accordance with the then current rules for resolution of employment disputes of
the American Arbitration Association ("AAA"). The parties are entitled to
representation by an attorney or other representative of their choosing. The
arbitrator shall have the power to enter any award that could be entered by a
judge of the trial court of the State of Arizona, and only such power, and shall
follow the law. The parties agree to abide by and perform any award rendered by
the arbitrator. Judgment on the award may be entered in any court having
jurisdiction thereof.

                  13.3     Costs of Arbitration. Each party shall bear one half
the cost of the arbitration filing and hearing fees, and the cost of the
arbitrator.

         14.      General Provisions.

                  14.1     Successors and Assigns. The rights and obligations of

upon the successors and assigns of Company. Executive shall not be entitled to
assign any of Executive's rights or obligations under this Agreement.

                  14.2     Waiver. Either party's failure to enforce any
provision of this Agreement shall not in any way be construed as a waiver of any
such provision, or prevent that party thereafter from enforcing each and every
other provision of this Agreement.

                  14.3     Attorneys' Fees. Each side will bear its own
attorneys' fees in any dispute unless a statutory section at issue, if any,
authorizes the award of attorneys' fees to the prevailing party.

                  14.4     Severability. In the event any provision of this
Agreement is found to be unenforceable by an arbitrator or court of competent
jurisdiction, such provision shall be deemed modified to the extent necessary to
allow enforceability of the provision as so limited, it being intended that the
parties shall receive the benefit contemplated herein to the fullest extent
permitted by law. If a deemed modification is not satisfactory in the judgment
of such arbitrator or court, the unenforceable provision shall be deemed
deleted, and the validity and enforceability of the remaining provisions shall
not be affected thereby.

                  14.5     Interpretation; Construction. The headings set forth
in this Agreement are for convenience only and shall not be used in interpreting
this Agreement. This Agreement has been drafted by legal counsel representing
Company, but Executive has participated in the negotiation of its terms.
Furthermore, Executive acknowledges that Executive has had an opportunity to
review and revise the Agreement and have it reviewed by legal counsel, if
desired, and, therefore, the normal rule of construction to the effect that any
ambiguities are to be resolved against the drafting party shall not be employed
in the interpretation of this Agreement.

                  14.6     Governing Law. This Agreement will be governed by and
construed in accordance with the laws of the United States and the State of
Arizona. Each party consents to the jurisdiction and venue of the state or

deemed given as indicated: (a) by personal delivery when delivered personally;

Rights"), 11 ("Nonsolicitation"), 12 ("Injunctive Relief"), 13 ("Agreement to
