     4.   ADMINISTRATION OF THE PLAN.
          --------------------------

          (a)  PROCEDURE.
               ---------

               (i)   MULTIPLE ADMINISTRATIVE BODIES. Different Committees with
                     ------------------------------
respect to different groups of Service Providers may administer the Plan.

               (ii)  SECTION 162(m). To the extent that the Administrator

determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

               (iii) RULE 16B-3. To the extent desirable to qualify transactions
                     ----------
hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder
shall be structured to satisfy the requirements for exemption under Rule 16b-3.

               (iv)  OTHER ADMINISTRATION. Other than as provided above, the
                     --------------------
Plan shall be administered by (A) the Board or (B) a Committee, which committee
shall be constituted to satisfy Applicable Laws.

          (b)  POWERS OF THE ADMINISTRATOR. Subject to the provisions of the
               ---------------------------
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

               (i)   to determine the Fair Market Value;

               (ii)  to select the Service Providers to whom Options may be
granted hereunder;

               (iii) to determine the number of shares of Common Stock to be
covered by each Option granted hereunder;

               (iv)  to approve forms of agreement for use under the Plan;

               (v)  to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any Option granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or
times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

               (vi)  to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan;

                                      -4-
<PAGE>

               (vii)  to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of satisfying applicable foreign laws;

               (viii) to modify or amend each Option (subject to Section 15(c)
of the Plan), including the discretionary authority to extend the post-
termination exercisability period of Options longer than is otherwise provided
for in the Plan;

               (ix)   to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option that number of Shares having a Fair Market Value equal to
the minimum amount required to be withheld. The Fair Market Value of the Shares
to be withheld shall be determined on the date that the amount of tax to be
withheld is to be determined. All elections by an Optionee to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable;

               (x)    to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option previously
granted by the Administrator;

               (xi)   to make all other determinations deemed necessary or
advisable for administering the Plan.

          (c)  EFFECT OF ADMINISTRATOR'S DECISION. The Administrator's
               ----------------------------------
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Shares issued under the Plan.

     5.   ELIGIBILITY. Nonstatutory Stock Options may be granted to Service
          -----------
Providers. Incentive Stock Options may be granted only to Employees.

     6.   LIMITATIONS.
          -----------

          (a)  Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (b)  Neither the Plan nor any Option shall confer upon an Optionee any
right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

          (c)  The following limitations shall apply to grants of Options:

                                      -5-
<PAGE>

               (i)   No Service Provider shall be granted, in any fiscal year of
the Company, Options to purchase more than 1,000,000 Shares.

               (ii)  In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 750,000 Shares,
which shall not count against the limit set forth in subsection (i) above.

               (iii) The foregoing limitations shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 13.

     7.   TERM OF PLAN. Subject to Section 19 of the Plan, the Plan shall become
          ------------
effective upon its adoption by the Board. It shall continue in effect for a term
of ten (10) years unless terminated earlier under Section 15 of the Plan.

     8.   TERM OF OPTION. The term of each Option shall be stated in the Option
          --------------
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement.

     9.   OPTION EXERCISE PRICE AND CONSIDERATION.
          ---------------------------------------

          (a)  EXERCISE PRICE. The per share exercise price for the Shares to be
               --------------
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A)  granted to an Employee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.

                    (B)  granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

               (ii) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                                      -6-
<PAGE>

               (iii)  Notwithstanding the foregoing, Options may be granted with
a per Share exercise price of less than 100% of the Fair Market Value per Share
on the date of grant pursuant to a merger or other corporate transaction.

          (b)  WAITING PERIOD AND EXERCISE DATES. At the time an Option is
               ---------------------------------
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

          (c)  FORM OF CONSIDERATION. The Administrator shall determine the
               ---------------------
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

               (i)    cash;

               (ii)   check;

               (iii)  promissory note;

               (iv)   other Shares which, in the case of Shares acquired
directly or indirectly from the Company, (A) have been owned by the Optionee for
more than six (6) months on the date of surrender, and (B) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which said Option shall be exercised;

               (v)    consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

               (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

               (vii)  any combination of the foregoing methods of payment; or

               (viii)  such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

Notwithstanding the foregoing, the Administrator may permit an Option to be
exercised by delivery of a full-recourse promissory note secured by the
purchased shares. All other terms of such promissory note shall be determined by
the Administrator in its sole discretion.

     10.  EXERCISE OF OPTION.
          ------------------

          (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option
               -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be suspended during any unpaid leave
of absence. An Option may not be exercised for a fraction of a Share.

                                      -7-
<PAGE>

               An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a STOCKHOLDER shall exist
                                                      -----------
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

               Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

          (b)  TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. If an Optionee
               -------------------------------------------------
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

          (c)  DISABILITY OF OPTIONEE. If an Optionee ceases to be a Service
               ----------------------
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

          (d)  DEATH OF OPTIONEE. If an Optionee dies while a Service Provider,
               -----------------
the Option may be exercised following Optionee's death within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of death (but in no event may the option be exercised later
than the expiration of the term of such Option as set forth in the Option
Agreement) by the Optionee's designated beneficiary, provided such beneficiary
has been designated

                                      -8-
<PAGE>

prior to Optionee's death in a form acceptable by the Administrator. If no such
beneficiary has been designated by the Optionee, then such Option may be
exercised by the personal representative of the Optionee's estate or by the
person(s) to whom the Option is transferred pursuant to the Optionee's will or
in accordance with the laws of descent and distribution. In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for
twelve (12) months following Optionee's death. If, at the time of death, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall immediately revert to the Plan. If the
Option is not so exercised within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

     11.  FORMULA OPTION GRANTS TO OUTSIDE DIRECTORS. Outside Directors shall
          ------------------------------------------
automatically be granted Options in accordance with the following provisions:

          (a)  All Options granted pursuant to this Section shall be

subject to the other terms and conditions of the Plan.

          (b)  Each Outside Director shall be automatically granted an Option to

               (iv)  subject to Section 13, the First Option shall become

     12.  LIMITED TRANSFERABILITY OF OPTIONS. Unless determined otherwise by the
          ----------------------------------
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

     13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR
          ------------------------------------------------------------------
ASSET SALE.
----------

               (a)  CHANGES IN CAPITALIZATION. Subject to any required action by
                    -------------------------
the stockholders of the Company, the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, the number of Shares that may be added annually to the
Plan pursuant to Section 3(i), the number of shares granted under First Options
and Subsequent Options under Section 11, and the number of shares of Common
Stock covered by each outstanding Option as well as the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

          (b)  DISSOLUTION OR LIQUIDATION. In the event of the proposed
               --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may

                                      -10-
<PAGE>

provide for an Optionee to have the right to exercise his or her Option until
ten (10) days prior to such transaction as to all of the Optioned Stock covered
thereby, including Shares as to which the Option would not otherwise be
exercisable. In addition, the Administrator may provide that any Company
repurchase option applicable to any Shares purchased upon exercise of an Option
shall lapse as to all such Shares, provided the proposed dissolution or
liquidation takes place at the time and in the manner contemplated. To the
extent it has not been previously exercised, an Option will terminate
immediately prior to the consummation of such proposed action.

          (c)  Merger or Asset Sale. In the event of a merger of the Company
               --------------------
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option shall be assumed or an equivalent option
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. In the event that the successor corporation refuses to
assume or substitute for the Option, the Optionee shall fully vest in and have
the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period. For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option immediately prior to the
merger or sale of assets, the consideration (whether stock, cash, or other
securities or property) received in the merger or sale of assets by holders of
Common Stock for each Share held on the effective date of the transaction (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Shares); provided,
however, that if such consideration received in the merger or sale of assets is
not solely common stock of the successor corporation or its Parent, the
Administrator may, with the consent of the successor corporation, provide for
the consideration to be received upon the exercise of the Option, for each Share
of Optioned Stock subject to the Option, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

     14.  Date of Grant. The date of grant of an Option shall be, for all
          -------------
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

     15.  Amendment and Termination of the Plan.
          --------------------------------------

          (a)  Amendment and Termination. The Board may at any time amend,
               -------------------------
alter, suspend or terminate the Plan.

          (b)  Stockholder Approval. The Company shall obtain stockholder
               --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

          (c)  Effect of Amendment or Termination. No amendment, alteration,
               ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise

                                      -11-
<PAGE>

between the Optionee and the Administrator, which agreement must be in writing
and signed by the Optionee and the Company. Termination of the Plan shall not
affect the Administrator's ability to exercise the powers granted to it
hereunder with respect to Options granted under the Plan prior to the date of
such termination.

          16.  Conditions Upon Issuance of Shares.
               ----------------------------------

               (a)  Legal Compliance. Shares shall not be issued pursuant to the
                    ----------------
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

               (b)  Investment Representations. As a condition to the exercise
                    --------------------------
of an Option, the Company may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

          17.  Inability to Obtain Authority. The inability of the Company
               -----------------------------
to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

          18.  Reservation of Shares. The Company, during the term of this Plan,
               ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

          19.  Stockholder Approval. The Plan shall be subject to approval by
               --------------------
the stockholders of the Company within twelve (12) months after the date the
Plan is adopted. Such stockholder approval shall be obtained in the manner and
to the degree required under Applicable Laws.

II.     AGREEMENT
        ---------

        A.    Grant of Option.
              ---------------

              The Plan Administrator of the Company hereby grants to the
Optionee named in the Notice of Grant attached as Part I of this Agreement (the
"Optionee") an option (the "Option") to purchase the number of Shares, as set
forth in the Notice of Grant, at the exercise price per Share set forth in the
Notice of Grant (the "Exercise Price"), subject to the terms and conditions of
the Plan, which is incorporated herein by reference. Subject to Section 15(c) of
the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

              If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code. However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

        B.    Exercise of Option.
              ------------------

              (a)  Right to Exercise. This Option shall be exercisable during
                   -----------------
its term in accordance with the Vesting Schedule set out in the Notice of Grant
and the applicable provisions of the Plan and this Option Agreement.

              (b)  Method of Exercise. This Option shall be exercisable by
                   ------------------
delivery of an exercise notice, in the form attached as Exhibit A (the "Exercise
Notice"), which shall state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the "Exercised
Shares"), and such other representations and agreements as may be required by
the Company. The Exercise Notice shall be accompanied by payment of the
aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed
to be exercised upon receipt by the Company of such fully executed Exercise
Notice accompanied by such aggregate Exercise Price.

                    No Shares shall be issued pursuant to the exercise of this
Option unless such issuance and exercise complies with Applicable Laws. Assuming
such compliance, for income tax purposes the Exercised Shares shall be
considered transferred to the Optionee on the date the Option is exercised with
respect to such Exercised Shares.

                                      -2-
<PAGE>

     C.   Method of Payment.

          Payment of the aggregate Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Optionee:

          1. cash; or

          2. check; or

          3.  consideration received by the Company from a brokerage firm under
a formal cashless exercise program approved by the Company in connection with
the Plan; or

          4.  surrender of other Shares which (i) in the case of Shares acquired
from the Company, either directly or indirectly, have been owned by the Optionee
for more than six (6) months on the date of surrender, and (ii) have a Fair
Market Value on the date of surrender equal to the aggregate Exercise Price of
the Exercised Shares.

     D.   Non-Transferability of Option.
          -----------------------------

          This Option may not be transferred in any manner otherwise than by
will or by the laws of descent or distribution and may be exercised during the
lifetime of Optionee only by the Optionee. The terms of the Plan and this Option
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

     E.   Term of Option.
          --------------

          This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with
the Plan and the terms of this Option Agreement.

     F.   Tax Obligations.
          ---------------

          1. Withholding Taxes.  Optionee agrees to make appropriate
             -----------------
arrangements with the Company (or the Parent or Subsidiary employing or
retaining Optionee) for the satisfaction of all Federal, state, local and
foreign income and employment tax withholding requirements applicable to the
Option exercise. Optionee acknowledges and agrees that the Company may refuse to
honor the exercise and refuse to deliver Shares if such withholding amounts are
not delivered at the time of exercise.

          2. Notice of Disqualifying Disposition of ISO Shares. If the Option
             -------------------------------------------------
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

Agreement constitute the entire agreement of the parties with respect to the

          (b)  Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent that,

to the applicable Enrollment Date.

          (b)  Payroll deductions for a participant shall commence on the first

terminated by the participant as provided in Section 10 hereof.

                                      -3-
<PAGE>

     6.   Payroll Deductions.
          ------------------

          (a)  At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding fifteen percent (15%) of
the Compensation which he or she receives on each pay day during the Offering
Period; provided, however, that should a pay day occur on an Exercise Date, a
participant shall have the payroll deductions made on such day applied to his or
her account under the new Offering Period or Purchase Period, as the case may
be.

          (b)  All payroll deductions made for a participant shall be credited
to his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

          (c)  A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Company may, in its discretion, limit the nature and/or
number of participation rate changes during any Offering Period, and may
establish such other conditions or limitations as it deems appropriate for Plan
administration. The change in rate shall be effective with the first full
payroll period following five (5) business days after the Company's receipt of
the new subscription agreement unless the Company elects to process a given
change in participation more quickly. A participant's subscription agreement
shall remain in effect for successive Offering Periods unless terminated as
provided in Section 10 hereof.

          (d)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during a
Purchase Period. Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Purchase
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

          (e)  At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

     7.   Grant of Option. On the Enrollment Date of each Offering Period, each
          ---------------
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than
2,000 shares of the Company's Common Stock

                                      -4-
<PAGE>

(subject to any adjustment pursuant to Section 19), and provided further that
such purchase shall be subject to the limitations set forth in Sections 3(b) and
12 hereof. The Board may, for future Offering Periods, increase or decrease, in
its absolute discretion, the maximum number of shares of the Company's Common
Stock an Employee may purchase during each Purchase Period of such Offering
Period. Exercise of the option shall occur as provided in Section 8 hereof,
unless the participant has withdrawn pursuant to Section 10 hereof. The option
shall expire on the last day of the Offering Period.

     8.   Exercise of Option.
          ------------------

          (a)  Unless a participant withdraws from the Plan as provided in
Section 10 hereof, his or her option for the purchase of shares shall be
exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

          (b)  If the Board determines that, on a given Exercise Date, the
number of shares with respect to which options are to be exercised may exceed
(i) the number of shares of Common Stock that were available for sale under the
Plan on the Enrollment Date of the applicable Offering Period, or (ii) the
number of shares available for sale under the Plan on such Exercise Date, the
Board may in its sole discretion (x) provide that the Company shall make a pro
rata allocation of the shares of Common Stock available for purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Exercise Date, and continue all Offering Periods then in effect, or (y) provide
that the Company shall make a pro rata allocation of the shares available for
purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform
a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Exercise Date, and terminate any or all Offering Periods
then in effect pursuant to Section 20 hereof. The Company may make pro rata
allocation of the shares available on the Enrollment Date of any applicable
Offering Period pursuant to the preceding sentence, notwithstanding any
authorization of additional shares for issuance under the Plan by the Company's
stockholders subsequent to such Enrollment Date.

     9.   Delivery. As promptly as practicable after each Exercise Date on which
          --------
a purchase of shares occurs, the Company shall arrange the delivery to each
participant, as appropriate, of a certificate representing the shares purchased
upon exercise of his or her option.

                                      -5-
<PAGE>

     10.  Withdrawal.
          ----------

          (a)  A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account shall be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period shall be automatically terminated, and no further payroll deductions for
the purchase of shares shall be made for such Offering Period. If a participant
withdraws from an Offering Period, payroll deductions shall not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

          (b)  A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11.  Termination of Employment.
          -------------------------

          Upon a participant's ceasing to be an Employee, for any reason, he or
she shall be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 15 hereof, and such participant's option shall be automatically
terminated. The preceding sentence notwithstanding, a participant who receives
payment in lieu of notice of termination of employment shall be treated as
continuing to be an Employee for the participant's customary number of hours per
week of employment during the period in which the participant is subject to such
payment in lieu of notice.

     12.  Interest.  No interest shall accrue on the payroll deductions of a
          --------
participant in the Plan.

     13.  Stock.
          -----

          (a)  Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 500,000 shares, plus an annual increase to be added on the first day
of the Company's fiscal year, beginning in 2001, equal to the lesser of (i)
500,000 shares, (ii) 1% of the outstanding shares of Common Stock on the last
day of the immediately preceding fiscal year, or (iii) an amount determined by
the Board.

          (b)  The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

          (c)  Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

                                      -6-
<PAGE>

     14.  Administration. The Plan shall be administered by the Board or a
          --------------
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

     15.  Designation of Beneficiary.
          --------------------------

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash. In addition, a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to exercise of the
option. If a participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

          (b)  Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

     16.  Transferability. Neither payroll deductions credited to a
          ---------------
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

     17.  Use Of Funds. All payroll deductions received or held by the Company
          ------------
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     18.  Reports. Individual accounts shall be maintained for each participant
          -------
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

     19.  Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
          ---------------------------------------------------------------------
Merger or Asset Sale.
--------------------

          (a)  Changes in Capitalization. Subject to any required action by the
               -------------------------
stockholders of the Company, the Reserves (including the number of shares
automatically added annually to the Plan pursuant to Section 13(a)(i)), the
maximum number of shares each participant may purchase each Purchase Period
(pursuant to Section 7), as well as the price per share and the number of shares
of Common Stock covered by each option under the Plan which has not yet been
exercised shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration." Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an option.

          (b)  Dissolution or Liquidation. In the event of the proposed
               --------------------------
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

          (c)  Merger or Asset Sale. In the event of a proposed sale of all or
               --------------------
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, any Purchase Periods
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date") and any Offering Periods then in progress shall end on the New
Exercise Date. The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

                                      -8-

     20.  Amendment or Termination.
          ------------------------

          (a)  The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in Section 19 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its stockholders. Except as provided
in Section 19 and this Section 20 hereof, no amendment may make any change in
any option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any successor rule or provision or any other applicable law, regulation or stock
exchange rule), the Company shall obtain stockholder approval in such a manner
and to such a degree as required.

          (b)  Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

          (c)  In the event the Board determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Board
may, in its discretion and, to the extent necessary or desirable, modify or
amend the Plan to reduce or eliminate such accounting consequence including, but
not limited to:

               (i)   altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase
Price;

               (ii)  shortening any Offering Period so that Offering Period ends
on a new Exercise Date, including an Offering Period underway at the time of the
Board action; and

               (iii) allocating shares.

                            SUBSCRIPTION AGREEMENT

_____ Original Application                           Enrollment Date:___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)

1.    ____________________ hereby elects to participate in the Top Tier
      Software, Inc. Employee Stock Purchase Plan (the "Employee Stock Purchase
      Plan") and subscribes to purchase shares of the Company's Common Stock in
      accordance with this Subscription Agreement and the Employee Stock
      Purchase Plan.

2.    I hereby authorize payroll deductions from each paycheck in the amount of
      ____% of my Compensation on each payday (from 0 to ___ %) during the
      Offering Period in accordance with the Employee Stock Purchase Plan.
      (Please note that no fractional percentages are permitted.)

3.    I understand that said payroll deductions shall be accumulated for the
      purchase of shares of Common Stock at the applicable Purchase Price
      determined in accordance with the Employee Stock Purchase Plan. I
      understand that if I do not withdraw from an Offering Period, any
      accumulated payroll deductions will be used to automatically exercise my
      option.

4.    I have received a copy of the complete Employee Stock Purchase Plan. I
      understand that my participation in the Employee Stock Purchase Plan is in
      all respects subject to the terms of the Plan. I understand that my
      ability to exercise the option under this Subscription Agreement is
      subject to stockholder approval of the Employee Stock Purchase Plan.

5.    Shares purchased for me under the Employee Stock Purchase Plan should be
      issued in the name(s) of (Employee or Employee and Spouse only).

6.    I understand that if I dispose of any shares received by me pursuant to
      the Plan within 2 years after the Enrollment Date (the first day of the
      Offering Period during which I purchased such shares) or one year after
      the Exercise Date, I will be treated for federal income tax purposes as
      having received ordinary income at the time of such disposition in an
      amount equal to the excess of the fair market value of the shares at the
      time such shares were purchased by me over the price which I paid for the
      shares. I hereby agree to notify the Company in writing within 30 days
              --------------------------------------------------------------
      after the date of any disposition of my shares and I will make adequate
      -----------------------------------------------------------------------
      provision for Federal, state or other tax withholding obligations, if any,
      --------------------------------------------------------------------------
      which arise upon the
      --------------------
<PAGE>

disposition of the Common Stock. The Company may, but will not be obligated to,
-------------------------------
withhold from my compensation the amount necessary to meet any applicable
withholding obligation including any withholding necessary to make available to
the Company any tax deductions or benefits attributable to sale or early
disposition of Common Stock by me. If I dispose of such shares at any time after
the expiration of the 2-year and 1-year holding periods, I understand that I
will be treated for federal income tax purposes as having received income only
at the time of such disposition, and that such income will be taxed as ordinary
income only to the extent of an amount equal to the lesser of (1) the excess of
the fair market value of the shares at the time of such disposition over the
purchase price which I paid for the shares, or (2) 15% of the fair market value
of the shares on the first day of the Offering Period. The remainder of the
gain, if any, recognized on such disposition will be taxed as capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
Plan. The effectiveness of this Subscription Agreement is dependent upon my
eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
beneficiary (ies) to receive all payments and shares due me under the Employee
Stock Purchase Plan:
