                           (e)      to amend, modify, extend, or renew, or grant

                           (f)      to accelerate, continue, extend or defer the

<PAGE>

the period following an Optionee's termination of employment or service with the
Participating Company Group;

                           (g)      to prescribe, amend or rescind rules,
guidelines and policies relating to the Plan, or to adopt supplements to, or
alternative versions of, the Plan, including, without limitation, as the Board
deems necessary or desirable to comply with the laws of, or to accommodate the
tax policy or custom of, foreign jurisdictions whose citizens may be granted
Options; and

                           (h)      to correct any defect, supply any omission
or reconcile any inconsistency in the Plan or any Option Agreement and to make
all other determinations and take such other actions with respect to the Plan or
any Option as the Board may deem advisable to the extent consistent with the
Plan and applicable law.

         4.       SHARES SUBJECT TO PLAN.

                  4.1      MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to
adjustment as provided in Section 4.2, the maximum aggregate number of shares of
Stock that may be issued under the Plan shall be Four Hundred Twelve Thousand
Five Hundred (412,500) and shall consist of authorized but unissued or
reacquired shares of Stock or any combination thereof. If an outstanding Option
for any reason expires or is terminated or canceled or shares of Stock acquired,
subject to repurchase, upon the exercise of an Option are repurchased by the
Company, the shares of Stock allocable to the unexercised portion of such
Option, or such repurchased shares of Stock, shall again be available for
issuance under the Plan.

                  4.2      ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the
event of any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of the
Company, appropriate adjustments shall be made in the number and class of shares
subject to the Plan and to any outstanding Options, and in the exercise price
per share of any outstanding Options. If a majority of the shares which are of
the same class as the shares that are subject to outstanding Options are
exchanged for, converted into, or otherwise become (whether or not pursuant to
an Ownership Change Event, as defined in Section 8.1) shares of another
corporation (the "NEW SHARES"), the Board may unilaterally amend the outstanding
Options to provide that such Options are exercisable for New Shares. In the
event of any such amendment, the number of shares subject to, and the exercise
price per share of, the outstanding Options shall be adjusted in a fair and
equitable manner as determined by the Board, in its sole discretion.
Notwithstanding the foregoing, any fractional share resulting from an adjustment
pursuant to this Section 4.2 shall be rounded up or down to the nearest whole
number, as determined by the Board, and in no event may the exercise price of
any Option be decreased to an amount less than the par value, if any, of the
stock subject to the Option. The adjustments determined by the Board pursuant to
this Section 4.2 shall be final, binding and conclusive.

         5.       ELIGIBILITY.

                  5.1      ELIGIBILITY AND OPTION LIMITATIONS. Options may be
granted to Employees, Consultants and Directors. For purposes of the foregoing
sentence, "Employees," "Consultants" and "Directors" shall include prospective
Employees, Consultants and Directors to whom Options are granted in connection
with written offers of engagement with the Participating Company Group. Eligible
persons may be granted more than one (1) Option.

                  5.2      RESTRICTIONS ON ELIGIBILITY. Notwithstanding the
foregoing, the maximum aggregate number of shares issued pursuant to Options
granted to Officers and Directors cannot exceed forty percent (40%) of the
aggregate number of shares reserved for issuance under the Plan as determined at
the time of each issuance to an Officer or Director.

         6.       TERMS AND CONDITIONS OF OPTIONS. Options shall be evidenced by
Option Agreements specifying the number of shares of Stock covered thereby, in
such form as the Board shall from time to time establish. Option Agreements may
incorporate all or any of the terms of the Plan by reference and shall comply
with and be subject to the following terms and conditions:

                  6.1      EXERCISE PRICE. The exercise price for each Option
shall be established in the sole discretion of the Board; provided, however,
that the exercise price per share for an Option shall be not less than the Fair
Market Value of a share of Stock on the effective date of grant of the Option.
Notwithstanding the foregoing, an Option may be granted with an exercise price
lower than the minimum exercise price set forth above if such Option is granted
pursuant to an assumption or substitution for another option in a manner
qualifying under the provisions of Section 424(a) of the Code.

                  6.2      EXERCISE PERIOD. Options shall be exercisable at such
time or times, or upon such event or events, and subject to such terms,
conditions, performance criteria, and restrictions as shall be determined by the
Board and set forth in the Option Agreement evidencing such Option; provided,
however, that no Option granted to a prospective Employee or prospective
Consultant may become exercisable prior to the date on which such person
commences service with a Participating Company.

                  6.3      PAYMENT OF EXERCISE PRICE.

                           (a)      FORMS OF CONSIDERATION AUTHORIZED. Except as
otherwise provided below, payment of the exercise price for the number of shares
of Stock being purchased pursuant to any Option shall be made (i) in cash, by
check, or cash equivalent, (ii) by tender to the Company of shares of Stock
owned by the Optionee having a Fair Market Value (as determined by the Company
without regard to any restrictions on transferability applicable to such stock
by reason of federal or state securities laws or agreements with an underwriter
for the Company) not less than the exercise price, (iii) by the assignment of
the proceeds of a sale or loan with respect to some or all of the shares being
acquired upon the exercise of the Option (including, without limitation, through
an exercise complying with the provisions of Regulation T as promulgated from
time to time by the Board of Governors of the Federal Reserve System) (a
"CASHLESS EXERCISE"), (iv) by the Optionee's promissory note in a form

                                       5
<PAGE>

approved by the Company, (v) by such other consideration as may be approved by
the Board from time to time to the extent permitted by applicable law, or (vi)
by any combination thereof. The Board may at any time or from time to time, by
adoption of or by amendment to the standard forms of Option Agreement described
in Section 7, or by other means, grant Options which do not permit all of the
foregoing forms of consideration to be used in payment of the exercise price or
which otherwise restrict one or more forms of consideration.

                           (b)      TENDER OF STOCK. Notwithstanding the
foregoing, an Option may not be exercised by tender to the Company of shares of
Stock to the extent such tender of Stock would constitute a violation of the
provisions of any law, regulation or agreement restricting the redemption of the
Company's stock. Unless otherwise provided by the Board, an Option may not be
exercised by tender to the Company of shares of Stock unless such shares either
have been owned by the Optionee for more than six (6) months or were not
acquired, directly or indirectly, from the Company.

                           (c)      CASHLESS EXERCISE. The Company reserves, at
any and all times, the right, in the Company's sole and absolute discretion, to
establish, decline to approve or terminate any program or procedures for the
exercise of Options by means of a Cashless Exercise.

                           (d)      PAYMENT BY PROMISSORY NOTE. No promissory
note shall be permitted if the exercise of an Option using a promissory note
would be a violation of any law. Any permitted promissory note shall be on such
terms as the Board shall determine at the time the Option is granted. The Board
shall have the authority to permit or require the Optionee to secure any
promissory note used to exercise an Option with the shares of Stock acquired
upon the exercise of the Option or with other collateral acceptable to the
Company. Unless otherwise provided by the Board, if the Company at any time is
subject to the regulations promulgated by the Board of Governors of the Federal
Reserve System or any other governmental entity affecting the extension of
credit in connection with the Company's securities, any promissory note shall
comply with such applicable regulations, and the Optionee shall pay the unpaid
principal and accrued interest, if any, to the extent necessary to comply with
such applicable regulations.

                  6.4      TAX WITHHOLDING. The Company shall have the right,
but not the obligation, to deduct from the shares of Stock issuable upon the
exercise of an Option, or to accept from the Optionee the tender of, a number of
whole shares of Stock having a Fair Market Value, as determined by the Company,
equal to all or any part of the federal, state, local and foreign taxes, if any,
required by law to be withheld by the Participating Company Group with respect
to such Option or the shares acquired upon the exercise thereof. Alternatively
or in addition, in its sole discretion, the Company shall have the right to
require the Optionee, through payroll withholding, cash payment or otherwise,
including by means of a Cashless Exercise, to make adequate provision for any
such tax withholding obligations of the Participating Company Group arising in
connection with the Option or the shares acquired upon the exercise thereof. The
Company shall have no obligation to deliver shares of Stock or to release shares
of Stock from an escrow established pursuant to the Option Agreement until the
Participating Company Group's tax withholding obligations have been satisfied by
the Optionee.

                                       6
<PAGE>

         7.       STANDARD FORM OF OPTION AGREEMENT.

                  7.1      GENERAL. Unless otherwise provided by the Board at
the time the Option is granted, an Option shall comply with and be subject to
the terms and conditions set forth in the form of Nonstatutory Stock Option
Agreement adopted by the Board concurrently with its adoption of the Plan and as
amended from time to time.

                  7.1      STANDARD TERM OF OPTIONS. Except as otherwise
provided by the Board in the grant of an Option, any Option granted hereunder
shall have a term of ten (10) years from the effective date of grant of the
Option.

                  7.3      AUTHORITY TO VARY TERMS. The Board shall have the
authority from time to time to vary the terms of any standard form of Option
Agreement described in this Section 7 either in connection with the grant or
amendment of an individual Option or in connection with the authorization of a
new standard form or forms; provided, however, that the terms and conditions of
any such new, revised or amended standard form or forms of Option Agreement are
not inconsistent with the terms of the Plan.

         8.       TRANSFER OF CONTROL.

                  8.1      DEFINITIONS.

                           (a)      An "OWNERSHIP CHANGE EVENT" shall be deemed
to have occurred if any of the following occurs with respect to the Company:

                                    (i)      the direct or indirect sale or
exchange in a single or series of related transactions by the stockholders of
the Company of more than fifty percent (50%) of the voting stock of the Company;

                                    (ii)     a merger or consolidation in which
the Company is a party;

                                    (iii)    the sale, exchange, or transfer of
all or substantially all of the assets of the Company; or

                                    (iv)     a liquidation or dissolution of the
Company.

                           (b)      A "TRANSFER OF CONTROL" shall mean an
Ownership Change Event or a series of related Ownership Change Events
(collectively, the "TRANSACTION") wherein the stockholders of the Company
immediately before the Transaction do not retain immediately after the
Transaction, in substantially the same proportions as their ownership of shares
of the Company's voting stock immediately before the Transaction, direct or
indirect beneficial ownership of more than fifty percent (50%) of the total
combined voting power of the outstanding voting stock of the Company or the
corporation or corporations to which the assets of the Company were transferred
(the "TRANSFEREE CORPORATION(S)"), as the case may be. For purposes of the
preceding sentence, indirect beneficial ownership shall include, without
limitation, an interest resulting from ownership of the voting stock of one or
more corporations

                                       7
<PAGE>

which, as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

                  8.2      EFFECT OF TRANSFER OF CONTROL ON OPTIONS. In the
event of a Transfer of Control, the surviving, continuing, successor, or
purchasing corporation or parent corporation thereof, as the case may be (the
"ACQUIRING CORPORATION"), may either assume the Company's rights and obligations
under outstanding Options or substitute for outstanding Options substantially
equivalent options for the Acquiring Corporation's stock. Any Options which are
neither assumed or substituted for by the Acquiring Corporation in connection
with the Transfer of Control nor exercised as of the date of the Transfer of
Control shall terminate and cease to be outstanding effective as of the date of
the Transfer of Control. Notwithstanding the foregoing, shares acquired upon
exercise of an Option prior to the Transfer of Control and any consideration
received pursuant to the Transfer of Control with respect to such shares shall
continue to be subject to all applicable provisions of the Option Agreement
evidencing such Option except as otherwise provided in such Option Agreement.
Furthermore, notwithstanding the foregoing, if the corporation the stock of
which is subject to the outstanding Options immediately prior to an Ownership
Change Event described in Section 8.1(a)(i) constituting a Transfer of Control
is the surviving or continuing corporation and immediately after such Ownership
Change Event less than fifty percent (50%) of the total combined voting power of
its voting stock is held by another corporation or by other corporations that
are members of an affiliated group within the meaning of Section 1504(a) of the
Code without regard to the provisions of Section 1504(b) of the Code, the
outstanding Options shall not terminate unless the Board otherwise provides in
its sole discretion.

         9.       PROVISION OF INFORMATION. Each Optionee shall be given access
to information concerning the Company equivalent to that information generally
made available to the Company's common stockholders.

         10.      NONTRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, an Option shall be exercisable only by the Optionee or the Optionee's
guardian or legal representative. No Option shall be assignable or transferable
by the Optionee, except by will or by the laws of descent and distribution.

         11.      INDEMNIFICATION. In addition to such other rights of
indemnification as they may have as members of the Board or Officers or
employees of the Participating Company Group, members of the Board and any
Officers or employees of the Participating Company Group to whom authority to
act for the Board is delegated shall be indemnified by the Company against all
reasonable expenses, including attorneys' fees, actually and necessarily
incurred in connection with the defense of any action, suit or proceeding, or in
connection with any appeal therein, to which they or any of them may be a party
by reason of any action taken or failure to act under or in connection with the
Plan, or any right granted hereunder, and against all amounts paid by them in
settlement thereof (provided such settlement is approved by independent legal
counsel selected by the Company) or paid by them in satisfaction of a judgment
in any such action, suit or

                                       8
<PAGE>

proceeding, except in relation to matters as to which it shall be adjudged in
such action, suit or proceeding that such person is liable for gross negligence,
bad faith or intentional misconduct in duties; provided, however, that within
sixty (60) days after the institution of such action, suit or proceeding, such
person shall offer to the Company, in writing, the opportunity at its own
expense to handle and defend the same.

         12.      TERMINATION OR AMENDMENT OF PLAN. The Board may terminate or
amend the Plan at any time. However, no termination or amendment of the Plan may
adversely affect any then outstanding Option or any unexercised portion thereof,
without the consent of the Optionee, unless such termination or amendment is
necessary to comply with any applicable law or government regulation.

         IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies
that the foregoing JDA Software Group, Inc. 1998 Nonstatutory Stock Option Plan
was duly adopted by the Board on January 27, 1998.
