        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 Common Stock, initially shares of the Company's Common Stock, par value
$0.001 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 three million three hundred thousand
(3,300,000) Shares, plus the number of Shares previously authorized and
remaining available under the Company's 1993 Stock Incentive Plan, as amended,
as of the Public Trading Date, plus any Shares covered by options granted under
the Company's 1993 Stock Incentive Plan that are forfeited or expire unexercised
or otherwise become available after the Public Trading Date; provided, however,
that the maximum aggregate number of Shares which may be issued upon exercise of
Incentive Stock Options is three million three hundred thousand (3,300,000)
Shares. 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. Unless and until the Board delegates
administration to a Committee as set forth below, the Plan shall be administered
by the Board. The Board may delegate administration of the Plan to a Committee
or Committees of one or more members of the Board, and the term "Committee"
shall apply to any person or persons to whom such authority has been delegated.
If administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the Board, including the power to delegate to a subcommittee any of the
administrative powers the Committee is authorized to exercise (and references in
this Plan to the Board shall thereafter be to the Committee or subcommittee),
subject, however, to such resolutions, not inconsistent with the provisions of
the Plan, as may be adopted from time to time by the Board. Notwithstanding the
foregoing, however, from and after the Public Trading Date, a Committee of the
Board shall administer the Plan and the Committee 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

                                       5
<PAGE>   8

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 sole discretion:

                     (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;

                                       6
<PAGE>   9

                     (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. 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 three million
(3,000,000) Shares; provided, however, that the foregoing limitation shall not
apply prior to the Public Trading Date and, following the Public Trading Date,
the foregoing limitation shall not apply until the earliest of: (i) the first
material modification of the Plan (including any increase in the number of
shares reserved for issuance under the Plan in accordance with Section 3); (ii)
the issuance of all of the shares of Common Stock reserved for issuance under
the Plan; (iii) the expiration of the Plan; (iv) the first meeting of
stockholders at which Directors of the Company are to be elected that occurs
after the close of the third calendar year following the calendar year in which
occurred the

                                       7
<PAGE>   10

first registration of an equity security of the Company under Section 12 of the
Exchange Act; or (v) such other date required by Section 162(m) of the Code and
the rules and regulations promulgated thereunder. 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 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

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 in this subsection (a)
above pursuant to a merger 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 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:

                                       9
<PAGE>   12

                     (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 sole discretion, deems necessary or advisable to effect
compliance with Applicable Laws. The Administrator may, in its sole 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.

              (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 sole
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
sole 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 sole
discretion of the Administrator may be in the form of consideration used by the
Holder to pay for such Shares under Section 9(b).

                                       10
<PAGE>   13

              (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. If a
Holder is terminated for Cause, the Option shall immediately 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 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

                                       11
<PAGE>   14

for issuance under the Plan. The Company shall notify the Holder's estate or the
person who acquires the right to exercise the Option by bequest or inheritance
of the existence of the Holder's outstanding Option and the date of the
expiration of the term of such Option as soon after the death of the Holder as
is practicable.

              (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 22, 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 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.

        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, 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 (i) an Option to purchase twenty-one thousand
six hundred (21,600) shares of Common Stock (subject to adjustment as provided
in Section 15) on the Public Trading Date or such initial election, as
applicable (each, an "Initial Option"), and (ii) an Option to purchase
twenty-one thousand six hundred (21,600) shares of Common Stock (subject to
adjustment as provided in Section 15) on the date of the first annual meeting of
stockholders that occurs in the third year after the Independent Director was
granted an Initial Option and at which the Independent Director is reelected to
the Board (a "Subsequent Option"). Members of the Board who are employees of the
Company who subsequently retire from the Company and remain on the Board will
not receive an initial Option grant pursuant to clause (i) of the preceding
sentence, but to the extent that they are otherwise eligible, will receive,
after retirement from employment with the Company, Options as described in
clause (ii) of the preceding sentence. All the

                                       12
<PAGE>   15

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;
provided, however, that the per Share price of each Option granted to an
Independent Director on the date of the initial public offering of Common Stock
shall equal the initial public offering price (net of underwriting discounts and
commissions) per Share. Initial Options (as defined in Section 12) granted to
Independent Directors shall become exercisable in cumulative annual installments
of one third (1/3) of the Shares subject to such option on each of the yearly
anniversaries of the date of Initial Option grant, commencing with the first
such anniversary, such that each Initial Option shall be one hundred percent
(100%) vested on the third anniversary of its date of grant. Subsequent Options
(as defined in Section 12) granted to Independent Directors shall become vested
in cumulative annual installments of one third (1/3) of the Shares subject to
such Option on each of the yearly anniversaries of the date of Subsequent Option
grant, commencing with the first anniversary of such date of Subsequent Option
grant, such that each Subsequent Option shall be one hundred percent (100%)
vested on the third anniversary of the date of Subsequent 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.
Subject to Section 22, the purchase price for Shares repurchased by the Company
pursuant to such repurchase right and the rate at which such repurchase right
shall lapse shall be determined by the Administrator in its sole discretion, and
shall be set forth in the Restricted Stock purchase agreement.

              (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.

                                       13
<PAGE>   16

              (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:

                     (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 calendar 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 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 by the
Company 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:

                                       14
<PAGE>   17

                     (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

                     (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 sole
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, the vesting
of such Options,

                                       15
<PAGE>   18

Stock Purchase Rights or Restricted Stock (and, if applicable, the time during
which such awards may be exercised) 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 (ii) 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) In the event the Company undergoes an Acquisition and any
surviving corporation or entity or acquiring corporation or entity does assume
any Options, Stock Purchase Rights or Restricted Stock outstanding under the
Plan (or substitutes similar stock awards, including an award to acquire the
same consideration paid to the stockholders in the transaction described in this
subsection 15(e), for those outstanding under the Plan), then, with respect to
each stock award held by participants in the Plan then performing services as
Employees or Directors, the vesting of each such stock award (and, if
applicable, the time during which such stock award may be exercised) shall be
accelerated and such stock award shall immediately become fully vested and
exercisable, if any of the following events occurs within nine (9) months after
the effective date of the Acquisition: (1) the Employee status or Director
status, as applicable, of the participant holding such stock award is terminated
by the Company without Cause; (2) the Employee holding such stock award
terminates his or her Employee status due to the fact that the principal place
of the performance of the responsibilities and duties of the Employee is changed
to a location more than fifty (50) miles from such Employee's existing work
location without the Employee's express consent (this clause (2) is not
applicable to Directors); or (3) the Employee holding such stock award
terminates his or her Employee status due to the fact that there is a material
reduction in such Employee's responsibilities and duties without the Employee's
express consent (this clause (3) is not applicable to Directors).

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

              (g) 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

                                       16
<PAGE>   19

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 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.

                                       17
<PAGE>   20

        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. Prior to the Public Trading
Date and to the extent required by Section 260.140.46 of Title 10 of the
California Code of Regulations, 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. Repurchase Provisions. The Administrator in its sole discretion may
provide that the Company may repurchase Shares acquired upon exercise of an
Option or Stock Purchase Right upon the occurrence of certain specified events,
including, without limitation, a Holder's termination as a Service Provider,
divorce, bankruptcy or insolvency; provided, however, that any such repurchase
right shall be set forth in the applicable Option Agreement or Restricted Stock
purchase agreement or in another agreement referred to in such agreement and,
provided further, that to the extent required by Section 260.140.41 and Section
260.140.42 of Title 10 of the California Code of Regulations, any such
repurchase right set forth in an Option or Stock Purchase Right granted prior to
the Public Trading Date to a person who is not an Officer, Director or
Consultant shall be upon the following terms: (i) if the repurchase option gives
the Company the right to repurchase the shares upon termination as a Service
Provider at not less than the Fair Market Value of the shares to be purchased on
the date of termination of status as a Service Provider, then (A) 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 or
Stock Purchase Rights 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
Administrator and the Plan participant and (B) the right terminates when the
shares become publicly traded; and (ii) 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 (A) 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 or Stock Purchase Right is granted (without respect to the date the
Option or Stock Purchase Right was exercised or became exercisable) and (B) 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 or Stock Purchase Rights, 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.

        23. 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

                                       18
<PAGE>   21

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.

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