3.  Stock Subject to the Plan. Subject to the provisions of Section 15 of the
    -------------------------
Plan, the shares of stock subject to Options or Stock Purchase Rights shall be
shares of the Company's Common Stock, par value $.001 per share. Subject to the
provisions of Section 15 of the Plan, the maximum aggregate number of Shares
which may be issued upon exercise of such Options or Stock Purchase Rights is
the sum of (i) 1,500,000 Shares, (ii) the number of Shares that remain reserved
for issuance under the Company's 1996 Incentive Stock Option Plan (the "1996
Plan") as of January 17, 2000 and (iii) the number of Shares that, after January
17, 2000 , again become available for issuance pursuant to Section 3 of the 1996
Plan as a result of stock options issued thereunder expiring or become
unexercisable for any reason before being exercised in full. Shares issued upon
exercise of Options or Stock Purchase Rights may be authorized but unissued, or
reacquired Common Stock. If an Option or Stock Purchase Right expires or becomes
unexercisable without having been exercised in full, the unpurchased Shares
which were subject thereto shall become available for future grant or sale under
the Plan (unless the Plan has terminated). Shares which are delivered by the
Holder or withheld by the Company upon the exercise of an Option or Stock
Purchase Right under the Plan, in payment of the exercise price thereof or tax
withholding thereon, may again be optioned, granted or awarded hereunder,
subject to the limitations of this Section 3. If Shares of Restricted Stock are
repurchased by the Company at their original purchase price, such Shares shall
become available for future grant under the Plan. Notwithstanding the provisions
of this Section 3, no Shares may again be optioned, granted or awarded if such
action would cause an Incentive Stock Option to fail to qualify as an Incentive
Stock Option under Code Section 422.

4.  Administration of the Plan.
    --------------------------
    (a)  Administrator. The Plan shall be administered by the Compensation
         -------------
Committee of the Board (or another committee or subcommittee of the Board
designated as the Administrator under the Plan) which shall consist solely of
two or more Independent Directors each of whom is both an "outside director,"
within the meaning of Section 162(m) of the Code, and a "non-employee director"
within the meaning of Rule 16b-3. Within the scope of such authority, the Board
or the Committee may (i) delegate to a committee of one or more members of the
Board who are not Independent Directors the authority to grant awards under the
Plan to eligible persons who are either (1) not then "covered employees," within
the meaning of Section 162(m) of the Code and are not expected to be "covered
employees" at the time of recognition of income resulting from such award or (2)
not persons with respect to whom the Company wishes to comply with Section
162(m) of the Code and/or (ii) delegate to a committee of one or more members of
the Board who are not "non-employee directors," within the meaning of Rule 16b-
3, the authority to grant awards under the Plan to eligible persons who are not
then subject to Section 16 of the Exchange Act. The Board may abolish the
Committee at any time and revest in the Board the administration of the Plan.
Appointment of Committee members shall be effective upon acceptance of
appointment. Committee members may resign at any time by delivering written
notice to the Board. Vacancies in the Committee may only be filled by the Board.

(b)  Powers of the Administrator.  Subject to the provisions of the Plan and the
     ---------------------------
specific duties delegated by the Board to such Committee, and subject to
the approval of any relevant authorities, the Administrator shall have the
authority in its discretion:

                                       4
<PAGE>

         (i)    to determine the Fair Market Value;

         (ii)   to select the Service Providers to whom Options and Stock
Purchase Rights may from time to time be granted hereunder;

         (iii)  to determine the number of Shares to be covered by each such
award granted hereunder;

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

         (v)    to determine the terms and conditions of any Option or Stock
Purchase Right granted hereunder (such terms and conditions include, but are not
limited to, the exercise price, the time or times when Options or Stock Purchase
Rights may vest or 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 Stock Purchase Right or the
Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine);

         (vi)   to determine whether to offer to buyout a previously granted
Option as provided in subsection 10(i) and to determine the terms and conditions
of such offer and buyout (including whether payment is to be made in cash or
Shares);

         (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 qualifying for preferred tax treatment under foreign tax
laws;

         (viii) to allow Holders to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option or Stock Purchase Right that number of Shares having a Fair Market
Value equal to the minimum amount required to be withheld based on the statutory
withholding rates for federal and state tax purposes that apply to supplemental
taxable income. 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 Holders 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;

         (ix)   to amend the Plan or any Option or Stock Purchase Right granted
under the Plan as provided in Section 17; and

         (x)    to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan and to exercise such powers and perform such acts
as the Administrator deems necessary or desirable to promote the best interests
of the Company which are not in conflict with the provisions of the Plan.

    (c)  Effect of Administrator's Decision.  All decisions, determinations and
         ----------------------------------
interpretations of the Administrator shall be final and binding on all Holders.

                                       5
<PAGE>

5.  Eligibility. Non-Qualified Stock Options and Stock Purchase Rights may be
    -----------
granted to Service Providers. Incentive Stock Options may be granted only to
Employees. If otherwise eligible, an Employee or Consultant who has been granted
an Option or Stock Purchase Right may be granted additional Options or Stock
Purchase Rights. Each Independent Director shall be eligible to be granted
Options at the times and in the manner set forth in Section 12.

6.  Limitations.
    -----------

    (a)  Each Option shall be designated by the Administrator in the Option
Agreement as either an Incentive Stock Option or a Non-Qualified Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of Shares subject to a Holder's Incentive Stock Options and
other incentive stock options granted by the Company, any Parent or Subsidiary,
which become exercisable for the first time during any calendar year (under all
plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess
Options or other options shall be treated as Non-Qualified 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, and the Fair Market Value
of the Shares shall be determined as of the time of grant.

    (b)  Neither the Plan, any Option nor any Stock Purchase Right shall confer
upon a Holder any right with respect to continuing the Holder's employment or
consulting relationship with the Company, nor shall they interfere in any way
with the Holder's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

    (c)  No Service Provider shall be granted, in any calendar year, Options or
Stock Purchase Rights to purchase more than 1,000,000 Shares. The foregoing
limitation shall be adjusted proportionately in connection with any change in
the Company's capitalization as described in Section 15. For purposes of this
Section 6(c), if an Option is canceled in the same calendar year it was granted
(other than in connection with a transaction described in Section 15), the
canceled Option will be counted against the limit set forth in this Section
6(c). For this purpose, if the exercise price of an Option is reduced, the
transaction shall be treated as a cancellation of the Option and the grant of a
new Option.

7.  Term of Plan. The Plan shall become effective upon its initial adoption by
    ------------
the Board and shall continue in effect until it is terminated under Section 17
of the Plan. No Options or Stock Purchase Rights may be issued under the Plan
after the tenth (10th) anniversary of the earlier of (i) the date upon which the
Plan is adopted by the Board or (ii) the date the Plan is approved by the
stockholders.

8.  Term of Option. The term of each Option shall be stated in the Option
    --------------
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to a Holder who, at the time the Option is granted, owns (or is treated as
owning under Code Section 424) stock representing

                                       6
<PAGE>

more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the 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)  Except as provided in Section 13, the per share exercise price for the
Shares to be issued upon exercise of an Option shall be such price as is
determined by the Administrator, but shall be subject to the following:

         (i)  In the case of an Incentive Stock Option

              (A)  granted to an Employee who, at the time of grant of such
Option, owns (or is treated as owning under Code Section 424) 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 one hundred ten percent (110%) of the Fair Market Value per Share on
the date of grant.

              (B)  granted to any other Employee, the per Share exercise price
shall be no less than one hundred percent (100%) of the Fair Market Value per
Share on the date of grant.

         (ii) In the case of a Non-Qualified Stock Option

              (A)  granted to a Service Provider who, at the time of grant of
such Option, 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
exercise price shall be no less than one hundred ten percent (110%) of the Fair
Market Value per Share on the date of the grant.

              (B)  granted to any other Service Provider, the per Share exercise
price shall be no less than eighty-five percent (85%) of the Fair Market Value
per Share on the date of grant.

         (iii)  Notwithstanding the foregoing, Options may be granted with a per
Share exercise price other than as required above pursuant to an Acquisition or
other corporate transaction.

    (b)  The consideration to be paid for the Shares to be issued upon exercise
of an Option, including the method of payment, shall be determined by the
Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) with the consent of the Administrator, a full recourse promissory
note bearing interest (at no less than such rate as shall then preclude the
imputation of interest under the Code) and payable upon such terms as may be
prescribed by the Administrator, (4) with the consent of the Administrator,
other Shares which (x) in the case of Shares acquired from the Company, have
been owned by the Holder for more than six (6) months on the date of surrender,
and (y) have a Fair Market Value on the date of surrender equal

                                       7
<PAGE>

to the aggregate exercise price of the Shares as to which such Option shall be
exercised, (5) with the consent of the Administrator, surrendered Shares then
issuable upon exercise of the Option having a Fair Market Value on the date of
exercise equal to the aggregate exercise price of the Option or exercised
portion thereof, (6) property of any kind which constitutes good and valuable
consideration, (7) with the consent of the Administrator, delivery of a notice
that the Holder has placed a market sell order with a broker with respect to
Shares then issuable upon exercise of the Options and that the broker has been
directed to pay a sufficient portion of the net proceeds of the sale to the
Company in satisfaction of the Option exercise price, provided, that payment of
such proceeds is then made to the Company upon settlement of such sale, or (8)
with the consent of the Administrator, any combination of the foregoing methods
of payment.

10.  Exercise of Option.
     ------------------

    (a)  Vesting; Fractional Exercises. Except as provided in Section 13,
          ----------------------------
Options granted hereunder shall be vested and exercisable according to the terms
hereof at such times and under such conditions as determined by the
Administrator and set forth in the Option Agreement; provided, however, that,
except with regard to Options granted to Officers, Directors or Consultants, in
no event shall an Option granted hereunder become vested and exercisable at a
rate of less than twenty percent (20%) per year over five (5) years from the
date the Option is granted, subject to reasonable conditions, such as continuing
to be a Service Provider. An Option may not be exercised for a fraction of a
Share.

    (b)  Deliveries upon Exercise. All or a portion of an exercisable Option
         ------------------------
shall be deemed exercised upon delivery of all of the following to the Secretary
of the Company or his or her office:

         (i)  A written or electronic notice complying with the applicable rules
established by the Administrator stating that the Option, or a portion thereof,
is exercised. The notice shall be signed by the Holder or other person then
entitled to exercise the Option or such portion of the Option ;

         (ii) Such representations and documents as the Administrator, in its
absolute discretion, deems necessary or advisable to effect compliance with
Applicable Laws. The Administrator may, in its absolute discretion, also take
whatever additional actions it deems appropriate to effect such compliance,
including, without limitation, placing legends on share certificates and issuing
stop transfer notices to agents and registrars;

         (iii) Upon the exercise of all or a portion of an unvested Option
pursuant to Section 10(h), a Restricted Stock purchase agreement in a form
determined by the Administrator and signed by the Holder or other person then
entitled to exercise the Option or such portion of the Option; and

         (iv) In the event that the Option shall be exercised pursuant to
Section 10(f) by any person or persons other than the Holder, appropriate proof
of the right of such person or persons to exercise the Option.

                                       8
<PAGE>

    (c)  Conditions to Delivery of Share Certificates.  The Company shall not be
         --------------------------------------------
required to issue or deliver any certificate or certificates for Shares
purchased upon the exercise of any Option or portion thereof prior to
fulfillment of all of the following conditions:

         (i)    The admission of such Shares to listing on all stock exchanges
on which such class of stock is then listed;

         (ii)   The completion of any registration or other qualification of
such Shares under any state or federal law, or under the rulings or regulations
of the Securities and Exchange Commission or any other governmental regulatory
body which the Administrator shall, in its absolute discretion, deem necessary
or advisable ;

         (iii)  The obtaining of any approval or other clearance from any state
or federal governmental agency which the Administrator shall, in its absolute
discretion, determine to be necessary or advisable;

         (iv)   The lapse of such reasonable period of time following the
exercise of the Option as the Administrator may establish from time to time for
reasons of administrative convenience; and

         (v)    The receipt by the Company of full payment for such Shares,
including payment of any applicable withholding tax, which in the discretion of
the Administrator may be in the form of consideration used by the Holder to pay
for such Shares under Section 9(b).

    (d)  Termination of Relationship as a Service Provider. If a Holder ceases
         -------------------------------------------------
to be a Service Provider other than by reason of the Holder's disability or
death, such Holder 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 the 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 Holder's termination. If, on the date of
termination, the Holder is not vested as to his or her entire Option, the Shares
covered by the unvested portion of the Option immediately cease to be issuable
under the Option and shall again become available for issuance under the Plan.
If, after termination, the Holder does not exercise his or her Option within the
time period specified herein, the Option shall terminate, and the Shares covered
by such Option shall again become available for issuance under the Plan.

    (e)  Disability of Holder. If a Holder ceases to be a Service Provider as a
         --------------------
result of the Holder's disability, the Holder 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 Holder's termination. If such
disability is not a "disability" as such term is defined in Section 22(e)(3) of
the Code, in the case of an Incentive Stock Option such Incentive Stock Option
shall automatically cease to be treated as an

                                       9
<PAGE>

Incentive Stock Option and shall be treated for tax purposes as a Non-Qualified
Stock Option from and after the day which is three (3) months and one (1) day
following such termination. If, on the date of termination, the Holder is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall immediately cease to be issuable under the Option
and shall again become available for issuance under the Plan. If, after
termination, the Holder does not exercise his or her Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall again become available for issuance under the Plan.

    (f)  Death of Holder. If a Holder dies while a Service Provider, the Option
         ---------------
may be exercised within such period of time as is specified in the Option
Agreement (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Holder's estate or by a person who
acquires the right to exercise the Option by bequest or inheritance, but only to
the extent that the Option is vested on the date of death. In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for
twelve (12) months following the Holder's termination. If, at the time of death,
the Holder is not vested as to his or her entire Option, the Shares covered by
the unvested portion of the Option shall immediately cease to be issuable under
the Option and shall again become available for issuance under the Plan. The
Option may be exercised by the executor or administrator of the Holder's estate
or, if none, by the person(s) entitled to exercise the Option under the Holder's
will or the laws of descent or distribution. If the Option is not so exercised
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall again become available for issuance under the Plan.

    (g)  Regulatory Extension. A Holder's Option Agreement may provide that if
         --------------------
the exercise of the Option following the termination of the Holder's status as a
Service Provider (other than upon the Holder's death or Disability) would be
prohibited at any time solely because the issuance of shares would violate the
registration requirements under the Securities Act, then the Option shall
terminate on the earlier of (i) the expiration of the term of the Option set
forth in Section 8 or (ii) the expiration of a period of three (3) months after
the termination of the Holder's status as a Service Provider during which the
exercise of the Option would not be in violation of such registration
requirements.

    (h)  Early Exercisability. The Administrator may provide in the terms of a
         --------------------
Holder's Option Agreement that the Holder may, at any time before the Holder's
status as a Service Provider terminates, exercise the Option in whole or in part
prior to the full vesting of the Option; provided, however, that subject to
Section 10(j), Shares acquired upon exercise of an Option which has not fully
vested may be subject to any forfeiture, transfer or other restrictions as the
Administrator may determine in its sole and absolute discretion.

    (i)  Buyout Provisions. The Administrator may at any time offer to buyout
         -----------------
for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Holder at the time that such offer is made.

                                       10
<PAGE>

    (j)  Repurchase Provisions.  The Administrator in its discretion may provide
         ---------------------
that the Company may repurchase Shares acquired upon exercise of an Option upon
a Holder's termination as a Service Provider for any reason (including death or
disability) provided, however that any such repurchase right shall be set forth
in the applicable Option Agreement or in another agreement referred to in such
agreement. If the repurchase option gives the Company the right to repurchase
the Shares upon termination as a Service Provider at the original purchase price
for such Shares, then (i) the right to repurchase at the original purchase price
shall lapse at the rate of at least twenty percent (20%) of the shares per year
over five (5) years from the date the Option is granted (without respect to the
date the Option was exercised or became exercisable) and (ii) the right to
repurchase shall be exercised for cash or cancellation of purchase money
indebtedness for the shares within ninety (90) days of termination of status as
a Service Provider (or, in the case of shares issued upon exercise of Options
after such date of termination, within ninety (90) days after the date of the
exercise) or such longer period as may be agreed to by the Company and the Plan
participant.

11.  Non-Transferability of Options and Stock Purchase Rights. Options and Stock
     --------------------------------------------------------
Purchase Rights 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 Holder, only by
the Holder.

12.  Granting of Options to Independent Directors. During the term of the Plan
     --------------------------------------------
and following the Public Trading Date, a person who is an Independent Director
as of the Public Trading Date, or a person who is initially elected to the Board
following the Public Trading Date and who is an Independent Director at the time
of such initial election, automatically shall be granted an Option to purchase
five thousand (5,000) shares of Common Stock (subject to adjustment as provided
in Section 15) on the date of each annual meeting of stockholders after the date
of the Board's adoption of the Plan following which the Independent Director
will continue to serve on the Board (an "Annual Option"). Members of the Board
who are employees of the Company who subsequently retire from the Company and
remain on the Board will receive, after retirement from employment with the
Company, Options as described in the preceding sentence. All the foregoing
Option grants authorized by this Section 12 are subject to stockholder approval
of the Plan.

13.  Terms of Options Granted to Independent Directors. The per Share price of
     -------------------------------------------------
each Option granted to an Independent Director shall equal 100% of the Fair
Market Value of a share of Common Stock on the date the Option is granted.
Annual Options (as defined in Section 12) granted to Independent Directors shall
become vested in cumulative monthly installments of 1/48 of the Shares subject
to such Option on each of the monthly anniversaries of the date of Annual Option
grant, commencing with the first such monthly anniversary, such that each Annual
Option shall be one hundred percent (100%) vested on the fourth anniversary of
the date of Annual Option grant. Subject to Section 10, the term of each Option
granted to an Independent Director shall be ten (10) years from the date the
Option is granted. No portion of an Option which is unexercisable at the time of
an Independent Director's termination of membership on the Board shall
thereafter become exercisable.

14.  Stock Purchase Rights.
     ---------------------

    (a)  Rights to Purchase. Stock Purchase Rights may be issued either alone,
         ------------------
in addition to, or in tandem with Options granted under the Plan and/or cash
awards made outside of the Plan. After the Administrator determines that it will
offer Stock Purchase Rights under the Plan, it shall advise the offeree in
writing of the terms, conditions and restrictions related to the offer,
including the number of Shares that such person shall be entitled to purchase,
the price to be paid, and the time within which such person must accept such
offer. The offer shall be accepted by execution of a Restricted Stock purchase
agreement in the form determined by the Administrator.

    (b)  Repurchase Right. Unless the Administrator determines otherwise, the
         ----------------
Restricted Stock purchase agreement shall grant the Company the right to
repurchase Shares acquired upon exercise of a Stock Purchase Right upon the
termination of the purchaser's status as a Service Provider for any reason. The
purchase price for Shares repurchased pursuant to the Restricted Stock purchase
agreement shall be the original price paid by the purchased and may be paid by
cancellation of any indebtedness of the purchaser to the Company. The repurchase
option shall lapse at such rate as the Administrator may determine, but in no
case at a rate of less than twenty percent (20%) per year over five (5) years
from the date of purchase.

    (c)  Other Provisions. The Restricted Stock purchase agreement shall contain
         ----------------
such other terms, provisions and conditions not inconsistent with the Plan as
may be determined by the Administrator in its sole discretion.

    (d)  Rights as a Shareholder. Once the Stock Purchase Right is exercised,
         -----------------------
the purchaser shall have rights equivalent to those of a shareholder and shall
be a shareholder when his or her purchase is entered upon the records of the
duly authorized transfer agent of the Company. No adjustment shall be made for a
dividend or other right for which the record date is prior to the date the Stock
Purchase Right is exercised, except as provided in Section 15 of the Plan.

15.  Adjustments upon Changes in Capitalization, Merger or Asset Sale.
     ----------------------------------------------------------------

    (a)  In the event that the Administrator determines that any dividend or
other distribution (whether in the form of cash, Common Stock, other securities,
or other property), recapitalization, reclassification, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, liquidation, dissolution, or sale, transfer, exchange
or other disposition of all or substantially all of the assets of the Company,
or exchange of Common Stock or other securities of the Company, issuance of
warrants or other rights to purchase Common Stock or other securities of the
Company, or other similar corporate transaction or event, in the Administrator's
sole discretion, affects the Common Stock such that an adjustment is determined
by the Administrator to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan or with respect to any Option, Stock Purchase Right or Restricted
Stock, then the Administrator shall, in such manner as it may deem equitable,
adjust any or all of:

                                       12
<PAGE>

         (i)    the number and kind of shares of Common Stock (or other
securities or property) with respect to which Options or Stock Purchase Rights
may be granted or awarded (including, but not limited to, adjustments of the
limitations in Section 3 on the maximum number and kind of shares which may be
issued and adjustments of the maximum number of Shares that may be purchased by
any Holder in any fiscal year pursuant to Section 6(c));

         (ii)   the number and kind of shares of Common Stock (or other
securities or property) subject to outstanding Options, Stock Purchase Rights or
Restricted Stock; and

         (iii)  the grant or exercise price with respect to any Option or Stock
Purchase Right.

    (b)  In the event of any transaction or event described in Section 15(a),
the Administrator, in its sole and absolute discretion, and on such terms and
conditions as it deems appropriate, either by the terms of the Option, Stock
Purchase Right or Restricted Stock or by action taken prior to the occurrence of
such transaction or event and either automatically or upon the Holder's request,
is hereby authorized to take any one or more of the following actions whenever
the Administrator determines that such action is appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan or with respect to any Option, Stock Purchase
Right or Restricted Stock granted or issued under the Plan or to facilitate such
transaction or event:

         (i)    To provide for either the purchase of any such Option, Stock
Purchase Right or Restricted Stock for an amount of cash equal to the amount
that could have been obtained upon the exercise of such Option or Stock Purchase
Right or realization of the Holder's rights had such Option, Stock Purchase
Right or Restricted Stock been currently exercisable or payable or fully vested
or the replacement of such Option, Stock Purchase Right or Restricted Stock with
other rights or property selected by the Administrator in its sole discretion;

         (ii)   To provide that such Option or Stock Purchase Right shall be
exercisable as to all shares covered thereby, notwithstanding anything to the
contrary in the Plan or the provisions of such Option or Stock Purchase Right;

         (iii)  To provide that such Option, Stock Purchase Right or Restricted
Stock be assumed by the successor or survivor corporation, or a parent or
subsidiary thereof, or shall be substituted for by similar options, rights or
awards covering the stock of the successor or survivor corporation, or a parent
or subsidiary thereof, with appropriate adjustments as to the number and kind of
shares and prices;

         (iv)   To make adjustments in the number and type of shares of Common
Stock (or other securities or property) subject to outstanding Options and Stock
Purchase Rights, and/or in the terms and conditions of (including the grant or
exercise price), and the criteria included in, outstanding Options, Stock
Purchase Rights or Restricted Stock or Options, Stock Purchase Rights or
Restricted Stock which may be granted in the future; and

                                       13
<PAGE>

         (v)  To provide that immediately upon the consummation of such event,
such Option or Stock Purchase Right shall not be exercisable and shall
terminate; provided, that for a specified period of time prior to such event,
such Option or Stock Purchase Right shall be exercisable as to all Shares
covered thereby, and the restrictions imposed under an Option Agreement or
Restricted Stock purchase agreement upon some or all Shares may be terminated
and, in the case of Restricted Stock, some or all shares of such Restricted
Stock may cease to be subject to repurchase, notwithstanding anything to the
contrary in the Plan or the provisions of such Option, Stock Purchase Right or
Restricted Stock purchase agreement.

    (c)  Subject to Section 3, the Administrator may, in its discretion, include
such further provisions and limitations in any Option, Stock Purchase Right,
Restricted Stock agreement or certificate, as it may deem equitable and in the
best interests of the Company.

    (d)  If the Company undergoes an Acquisition, then any surviving corporation
or entity or acquiring corporation or entity, or affiliate of such corporation
or entity, may assume any Options, Stock Purchase Rights or Restricted Stock
outstanding under the Plan or may substitute similar stock awards (including an
award to acquire the same consideration paid to the stockholders in the
transaction described in this subsection 15(d)) for those outstanding under the
Plan. In the event any surviving corporation or entity or acquiring corporation
or entity in an Acquisition does not assume such Options, Stock Purchase Rights
or Restricted Stock or does not substitute similar stock awards for those
outstanding under the Plan, then with respect to (i) Options, Stock Purchase
Rights or Restricted Stock held by participants in the Plan whose status as a
Service Provider has not terminated prior to such event, except Independent
Directors, the vesting of such Options, Stock Purchase Rights or Restricted
Stock (and, if applicable, the time during which such awards may be exercised)
may be accelerated and made fully exercisable and all restrictions thereon shall
lapse at least ten (10) days prior to the closing of the Acquisition (and the
Options or Stock Purchase Rights terminated if not exercised prior to the
closing of such Acquisition), (ii) Options, Stock Purchase Rights or Restricted
Stock held by Independent Directors whose status as a Service Provider has not
terminated prior to such event, the vesting of such Options, Stock Purchase
Rights or Restricted Stock shall be accelerated and made fully exercisable and
all restrictions thereon shall lapse at least ten (10) days prior to the closing
of the Acquisition (and the Options or Stock Purchase Rights terminated if not
exercised prior to the closing of such Acquisition), and (iii) any other Options
or Stock Purchase Rights outstanding under the Plan, such Options or Stock
Purchase rights shall be terminated if not exercised prior to the closing of the
Acquisition.

    (e)  Notwithstanding the foregoing, in the event that the Company becomes a
party to a transaction that is intended to qualify for "pooling of interests"
accounting treatment and, but for one or more of the provisions of this Plan or
any Option Agreement or any Restricted Stock purchase agreement would so
qualify, then this Plan and any such agreement shall be interpreted so as to
preserve such accounting treatment, and to the extent that any provision of the
Plan or any such agreement would disqualify the transaction from pooling of
interests accounting treatment (including, if applicable, an entire Option
Agreement or Restricted Stock purchase agreement), then such provision shall be
null and void. All determinations to be made in connection with the preceding
sentence shall be made by the independent accounting

                                       14
<PAGE>

firm whose opinion with respect to "pooling of interests" treatment is required
as a condition to the Company's consummation of such transaction.

    (f)  The existence of the Plan, any Option Agreement or Restricted Stock
purchase agreement and the Options or Stock Purchase Rights granted hereunder
shall not affect or restrict in any way the right or power of the Company or the
stockholders of the Company to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's capital
structure or its business, any merger or consolidation of the Company, any issue
of stock or of options, warrants or rights to purchase stock or of bonds,
debentures, preferred or prior preference stocks whose rights are superior to or
affect the Common Stock or the rights thereof or which are convertible into or
exchangeable for Common Stock, or the dissolution or liquidation of the Company,
or any sale or transfer of all or any part of its assets or business, or any
other corporate act or proceeding, whether of a similar character or otherwise.

16.  Time of Granting Options and Stock Purchase Rights. The date of grant of an
     --------------------------------------------------
Option or Stock Purchase Right shall, for all purposes, be the date on which the
Administrator makes the determination granting such Option or Stock Purchase
Right, or such other date as is determined by the Administrator. Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

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

    (a)  Amendment and Termination. The Board may at any time wholly or
         -------------------------
partially amend, alter, suspend or terminate the Plan. However, without approval
of the Company's stockholders given within twelve (12) months before or after
the action by the Board, no action of the Board may, except as provided in
Section 15, increase the limits imposed in Section 3 on the maximum number of
Shares which may be issued under the Plan or extend the term of the Plan under
Section 7.

    (b)  Stockholder Approval. The Board 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 Holder,
unless mutually agreed otherwise between the Holder and the Administrator, which
agreement must be in writing and signed by the Holder 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, Stock Purchase
Rights or Restricted Stock granted or awarded under the Plan prior to the date
of such termination.

18. Stockholder Approval. The Plan will be submitted for the approval of the
    --------------------
Company's stockholders within twelve (12) months after the date of the Board's
initial adoption of the Plan. Options, Stock Purchase Rights or Restricted Stock
may be granted or awarded prior to such stockholder approval, provided that such
Options, Stock Purchase Rights and Restricted Stock shall not be exercisable,
shall not vest and the restrictions thereon shall not lapse prior to

                                       15
<PAGE>

the time when the Plan is approved by the stockholders, and provided further
that if such approval has not been obtained at the end of said twelve-month
period, all Options, Stock Purchase Rights and Restricted Stock previously
granted or awarded under the Plan shall thereupon be canceled and become null
and void.

19.  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.

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

21.  Information to Holders and Purchasers. The Company shall provide to each
     -------------------------------------
Holder and to each individual who acquires Shares pursuant to the Plan, not less
frequently than annually during the period such Holder or purchaser has one or
more Options or Stock Purchase Rights outstanding, and, in the case of an
individual who acquires Shares pursuant to the Plan, during the period such
individual owns such Shares, copies of annual financial statements.
Notwithstanding the preceding sentence, the Company shall not be required to
provide such statements to key employees whose duties in connection with the
Company assure their access to equivalent information.

22.  Investment Intent. The Company may require a Plan participant, as a
     -----------------
condition of exercising or acquiring stock under any Option or Stock Purchase
Right, (i) to give written assurances satisfactory to the Company as to the
participant's knowledge and experience in financial and business matters and/or
to employ a purchaser representative reasonably satisfactory to the Company who
is knowledgeable and experienced in financial and business matters and that he
or she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Option or Stock Purchase
Right; and (ii) to give written assurances satisfactory to the Company stating
that the participant is acquiring the stock subject to the Option or Stock
Purchase Right for the participant's own account and not with any present
intention of selling or otherwise distributing the stock. The foregoing
requirements, and any assurances given pursuant to such requirements, shall be
inoperative if (A) the issuance of the shares upon the exercise or acquisition
of stock under the applicable Option or Stock Purchase Right has been registered
under a then currently effective registration statement under the Securities Act
or (B) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

23.  Governing Law. The validity and enforceability of this Plan shall be
     -------------
governed by and construed in accordance with the laws of the State of California
without regard to otherwise governing principles of conflicts of law.

     2.  Stock Subject to the Plan. Subject to the provisions of Section 9
         -------------------------
hereof (relating to adjustments upon changes in the Stock) and Section 11 hereof
(relating to amendments of the Plan), the Stock that may be sold pursuant to
Options granted under the Plan shall not exceed in the aggregate 200,000 shares
of Stock. The shares of Stock sold pursuant to Options granted under the Plan
may be unissued shares or treasury shares of Stock, or shares of Stock bought on
the Nasdaq National Market ("Nasdaq") or other nationally-recognized exchange,
or other market, for purposes of the Plan.

     3.  Grant of Options.
         ----------------

         (a)  Option Grants.  The Company shall grant Options under the Plan to
              -------------
all Eligible Employees in successive Offering Periods until the earlier of: (i)
the date when the number of shares of Stock available under the Plan have been
sold, or (ii) the date when the Plan is terminated. Each Employee who is an
Eligible Employee on an Entry Date for any Offering Period shall be granted an
Option with respect to such Offering Period as of such date. The Date of Grant
of an Option shall be the first day of the Offering Period with respect to which
such Option was granted. Each Option shall expire on the Date of Exercise
immediately after the automatic exercise of the Option pursuant to Section 4(a).

         The number of shares of Stock subject to a Participant's Option shall
equal the payroll deductions authorized by such Participant in accordance with
subsection (b) for the Purchase Period, divided by the Option Price, except as
provided in Section 5(a); provided, however, that the maximum number of shares
of Stock that may be purchased by any Participant on a Date of Exercise shall
not exceed 5,000.  The Company shall not grant an Option with respect to an
Offering Period to any individual who is not an Eligible Employee on the Entry
Date with respect to such Offering Period.

         (b)  Election to Participate; Payroll Deduction Authorization.  Except
              --------------------------------------------------------
as provided in subsection (d), an Eligible Employee shall participate in the
Plan only by means of payroll deduction. Each Eligible Employee who elects to
participate in the Plan with respect to an Offering Period shall deliver to the
Company no later than ten (10) days before his or her applicable Entry Date, a
completed and executed written payroll deduction authorization in a form
prepared by the Committee (the "Authorization"). An Eligible Employee's
Authorization shall give notice of such Eligible Employee's election to
participate in the Plan for the current or next following Offering Period (and
subsequent Offering Periods), as applicable, and shall designate a stated whole
percentage of such Eligible Employee's Base Compensation to be withheld by the
Company or Subsidiary Corporation employing such Eligible Employee on each
Payday during the Offering Period, which shall not be less than one percent
(1%), nor more than fifteen percent (15%), of Base Compensation. The Base
Compensation payable to a Participant for any Payday during and Offering Period
shall be reduced through payroll deduction in an

                                       4
<PAGE>

amount equal to the percentage specified in the Authorization, and such amount
shall be credited to the Participant's Account under the Plan.

         An Eligible Employee may change the percentage of Base Compensation
designated in the Authorization subject to the limits of this subsection, and
may suspend the Authorization, at any time during the Offering Period.  Any
Authorization shall remain in effect until the Eligible Employee changes or
suspends the same pursuant to this subsection, withdraws pursuant to Section 5,
or ceases to be an Eligible Employee pursuant to Section 6.

         (c)  $25,000 Limitation.  No Eligible Employee shall be granted an
              ------------------
Option under the Plan which permits his rights to purchase Stock under the Plan,
and to purchase Stock or other stock under all other employee stock purchase
plans of the Company, any Parent Corporation or any Subsidiary Corporation
subject to the Section 423, to accrue at a rate which exceeds $25,000 of fair
market value of such Stock or other stock (determined at the time the Option is
granted) for each calendar year in which the Option is outstanding at any time.

         For purpose of the limitation imposed by this subsection, the right to
purchase Stock or other stock under an Option or other option accrues when the
Option or other option (or any portion thereof) first becomes exercisable during
the calendar year, the right to purchase Stock or other stock under an Option or
other option accrues at the rate provided in the Option or other option, but in
no case may such rate exceed $25,000 of the fair market value of such Stock or
other stock (determined at the time such Option or other option is granted) for
any one calendar year, and a right to purchase Stock or other stock which has
accrued under an Option or other option may not be carried over to any Option or
other option.  This limitation shall be applied in accordance with Section
423(b)(8) of the Code and the Treasury Regulations thereunder.

         (d)  Leaves of Absence.  During a leave of absence meeting the
              -----------------
requirements of Treasury Regulation Section 1.421-7(h)(2), a Participant may
continue to participate in the Plan by making cash payments to the Company on
each Payday equal to the amount of the Participant's payroll deductions under
the Plan for the Payday immediately preceding the first day of such
Participant's leave of absence.

     4.  Exercise of Options; Option Price.
         ---------------------------------

         (a)  Option Exercise.  Each Participant automatically and without any
              ---------------
act on such Participant's part shall be deemed to have exercised such
Participant's Option on the Date of Exercise to the extent that the balance then
in the Participant's Account is sufficient to purchase, at the Option Price,
whole shares of the Stock subject to the Option. Fractional shares of Stock
shall not be sold pursuant to an Option.

         (b)  Option Price Defined.  The option price per share of Stock (the
              --------------------
"Option Price") to be paid by a Participant upon the exercise of the
Participant's Option shall be equal to 85% of the lesser of: (i) the Fair Market
Value of a share of Stock on the Date of Exercise or (ii) the Fair Market Value
of a share of Stock on the Participant's Entry Date for the Offering Period. The
Fair Market Value of a share of Stock as of a given date shall be: (A) the
closing price of a

                                       5
<PAGE>

share of Stock on the principal exchange on which the Stock is then trading, if
any, on such date, or, if shares of Stock were not traded on such date, then on
the next preceding trading day during which a sale occurred; (B) if the Stock is
not traded on an exchange, but is quoted on Nasdaq or a successor quotation
system, (X) the last sales price (if the Stock is then listed as a National
Market Issue under the NASD National Market System) or (Y) the mean between the
closing representative bid and asked prices (in all other cases) for a share of
Stock on such date, or, if shares of Stock were not traded on such date, then on
the next preceding trading day during which a sale occurred, as reported by
Nasdaq or such successor quotation system; (iii) if the Stock is not publicly
traded on an exchange and not quoted on Nasdaq or a successor quotation system,
the mean between the closing bid and asked prices for a share of Stock on such
date, or, if shares of Stock were not traded on such date, then on the next
preceding trading day during which a sale occurred, as determined in good faith
by the Committee; or (iv) if the Stock is not publicly traded, the fair market
value of a share of Stock established by the Committee acting in good faith.

         (c)  Book Entry/Share Certificates.  As soon as practicable after the
              -----------------------------
exercise of any Option by a Participant, the Company shall issue the shares of
Stock purchased upon such exercise to such Participant and such shares shall be
held in the custody of the Agent for the benefit of the Participant. The Company
or the Agent shall make an entry on its books and records indicating that the
shares of Stock purchased in connection with such exercise have been duly issued
as of that date to such Participant. A Participant shall have the right at any
time to request in writing a certificate or certificates for all or a portion of
the whole shares of Stock purchased hereunder. Upon receipt of a Participant's
written request for any such certificate, the Company shall (or shall cause the
Agent to), within fifteen (15) days after the date of such receipt, deliver any
such certificate to the Participant. Nothing in this subsection (c) shall
prohibit the sale or other disposition by a Participant of shares of Stock
purchased hereunder. In the event the Company is required to obtain authority
from any commission or agency to issue any certificate or certificates for
shares of Stock purchased hereunder, the Company shall seek to obtain such
authority as soon as reasonably practicable.

         (d)  Pro Rata Allocations.  If the total number of shares of Stock for
              --------------------
which Options are to be exercised on any date exceeds the number of shares of
Stock remaining unsold under the Plan (after deduction for all shares of Stock
for which Options have theretofore been exercised), the Committee shall make a
pro rata allocation of the available remaining shares of Stock in as nearly a
uniform manner as shall be practicable and the balance of the amount credited to
the Account of each Participant which has not been applied to the purchase of
shares of Stock shall be paid to such Participant in one lump sum in cash within
sixty (60) days after the Date of Exercise, without any interest thereon.

         (e)  Information Statement.  The Company shall provide each
              ---------------------
Participant whose Option is exercised with an information statement in
accordance with Section 6039(a) of the Code and the Treasury Regulations
thereunder. The Company shall maintain a procedure for identifying certificates
of shares of Stock sold upon the exercise of Options in accordance with Section
6039(b) of the Code.

     5.  Withdrawal from the Plan.
         ------------------------

         (a)  Withdrawal Election.  Any Participant may withdraw from
              -------------------
participation under the Plan at any time, except that no Participant may
withdraw during the last ten (10) days of any Purchase Period. A Participant
electing to withdraw from the Plan must deliver to the Company a notice of
withdrawal in a form prepared by the Committee (the "Withdrawal Election") not
later than ten (10) days prior to the Date of Exercise for such Purchase Period.
Upon receipt of a Participant's Withdrawal Election, the Company or Subsidiary
Corporation employing the Participant shall pay to the Participant the amount
credited to the Participant's Account in one lump sum in cash within sixty (60)
days, without any interest thereon. Upon receipt of a Participant's Withdrawal
Election by the Company, the Participant shall cease to participate in the Plan
and the Participant's Option for such Offering Period shall terminate.

         (b)  Eligibility following Withdrawal.  A Participant who withdraws
              --------------------------------
from the Plan with respect to a Purchase Period, and who is still an Eligible
Employee, may elect to participate again in the Plan for any subsequent Offering
Period by delivering to the Company an Authorization pursuant to Section 3(b).

     6.  Termination of Employment.
         -------------------------

         (a)  Termination of Employment Other than by Death.  If the employment
              ---------------------------------------------
of a Participant with the Company and the Subsidiary Corporation terminates
other than by death, the Participant's participation in the Plan automatically
and without any act on the Participant's part shall terminate as of the date of
the termination of the Participant's employment. As soon as practicable after
such a termination of employment, the Company or Subsidiary Corporation
employing the Participant shall pay to the Participant the amount of the balance
in the Participant's Account, without any interest thereon. Upon a Participant's
termination of employment covered by this subsection, the Participant's
Authorization and Option under the Plan shall terminate.

         (b)  Termination By Death.  If the employment of a Participant is
              --------------------
terminated by the Participant's death, the executor of the Participant's will or
the administrator of the Participant's estate, by written notice to the Company,
may request payment of the balance in the Participant's Account, in which event
the Company or Subsidiary Corporation employing the Participant shall make such
payment, without any interest thereon as soon as practicable after receiving
such notice. Upon receipt of such notice, the Participant's Authorization and
Option under the Plan shall terminate. If the Company does not receive such
notice prior to the next Date of Exercise, the Participant's Option shall be
deemed to have been exercised on such Date of Exercise.

     7.  Restriction upon Assignment.  An Option granted under the Plan shall
         ---------------------------
not be transferable other than by will or the laws of descent and distribution,
and is exercisable during the Participant's lifetime only by the Participant.
Except as provided in Section 6(b) hereof, an Option may not be exercised to any
extent except by the Participant. The Company shall not recognize and shall be
under no duty to recognize any assignment or alienation of the

                                       7
<PAGE>

Participant's interest in the Plan, the Participant's Option or any rights under
the Participant's Option.

     8.  No Rights of Stockholders until Shares Issued.  With respect to shares
         ---------------------------------------------
of Stock subject to an Option, a Participant shall not be deemed to be a
stockholder of the Company, and the Participant shall not have any of the rights
or privileges of a stockholder, until such shares have been issued to the
Participant or his or her nominee following exercise of the Participant's
Option. No adjustments shall be made for dividends (ordinary or extraordinary,
whether in cash securities, or other property) or distribution or other rights
for which the record date occurs prior to the date of such issuance, except as
otherwise expressly provided herein.

     9.  Changes in the Stock; Adjustments of an Option.  Whenever any change
         ----------------------------------------------
is made in the Stock or to Options outstanding under the Plan, by reason of a
stock split, stock dividend, recapitalization or other subdivision, combination,
or reclassification of shares, appropriate action shall be taken by the
Committee to adjust accordingly the number of shares of Stock subject to the
Plan and the number and the Option Price of shares of Stock subject to the
Options outstanding under the Plan to preserve, but not increase, the rights of
Participants hereunder.

     10. Use of Funds; no Interest Paid.  All funds received or held by the
         ------------------------------
Company under the Plan shall be included in the general funds of the Company
free of any trust or other restriction and may be used for any corporate
purpose. No interest will be paid to any Participant or credited to any
Participant's Account with respect to such funds.

     11. Amendment or Termination of the Plan.  The Board of Directors may
         ------------------------------------
amend, suspend, or terminate the Plan at any time and from time to time,
provided that approval by a vote of the holders of the outstanding shares of the
Company's capital stock entitled to vote shall be required to amend the Plan to:
(a) change the number of shares of Stock that may be sold pursuant to Options
under the Plan, (b) decrease the Option Price below a price computed in the
manner stated in Section 4(b), (c) alter the requirements for eligibility to
participate in the Plan, or (d) in any manner that would cause the Plan to no
longer be an "employee stock purchase plan" within the meaning of Section 423(b)
of the Code.

         --------------------------------------------------

         (a)  Appointment of Committee.  The Plan shall be administered by the
              ------------------------
Committee, which shall be composed of not less than two members of the Board of
Directors, none of whom shall be eligible to serve on the Committee, unless such

such Options in a manner complying with Section 424(a) of the Code.

     15. Term; Approval by Stockholders.  Subject to approval by the

provided, further, that if such approval has not been obtained by the end of
said 12-month period, all Options previously granted under the Plan shall
thereupon expire.
