         4. Administration of the Plan.

         (a) Procedure.

              (i) Multiple  Administrative  Bodies. The Plan may be administered
by different Committees with respect to different groups of Directors,  Officers
and Employees.

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

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

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

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

              (i) to  determine  the Fair Market Value of the Common  Stock,  in
accordance with Section 2(o) of the Plan;

              (ii) to select the  Consultants,  Directors  and Employees to whom
Options and Stock Purchase Rights may be granted hereunder;

              (iii) to  determine  whether and to what extent  Options and Stock
Purchase Rights or any combination thereof, are granted hereunder;

              (iv) to  determine  the  number of  shares  of Common  Stock to be
covered by each Option and Stock Purchase Right granted hereunder;

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

              (vi) to determine the terms and conditions,  not inconsistent with
the terms of the Plan, of any award 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 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 shares of Common Stock  relating  thereto,  based in each
case on  such  factors  as the  Administrator,  in its  sole  discretion,  shall
determine;

              (vii) to reduce the exercise price of any Option or Stock Purchase
Right to the then  current  Fair Market  Value if the Fair  Market  Value of the
Common Stock covered by such Option or Stock  Purchase Right shall have declined
since  the date the  Option  or Stock  Purchase  Right  was  granted  (provided,
however,  that the exercise  price of any Option or Stock Purchase Right granted
to Directors or Officers of the Company may not be so reduced);

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

              (ix)  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;

              (x) to  modify  or  amend  each  Option  or Stock  Purchase  Right
(subject to Section 15(c) of the Plan);

              (xi) to  authorize  any person to execute on behalf of the Company
any instrument required to effect the grant of an Option or Stock Purchase Right
previously granted by the Administrator;

              (xii) to institute an Option Exchange Program;

              (xiii)  to  determine  the terms and  restrictions  applicable  to
Options and Stock Purchase Rights and any Restricted Stock; and

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

         (c) Effect of Administrator's Decision. The Administrator's  decisions,
determinations and  interpretations  shall be final and binding on all Optionees
and any other holders of Options or Stock Purchase Rights.

         5.  Eligibility.  Nonstatutory  Stock Options and Stock Purchase Rights
may be granted to Employees, Directors and Consultants.  Incentive Stock Options
may be granted only to  Employees.  If otherwise  eligible,  an Optionee who has
been granted an Option or Stock Purchase Right may be granted additional Options
or Stock Purchase Rights.

         6. Limitations.

         (a) Each Option shall be designated in the Notice of Grant as either an
Incentive Stock Option or a Nonstatutory Stock Option. However,  notwithstanding
such designations,  to the extent that the aggregate Fair Market Value of Shares
subject to an Optionee's  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 shall be treated as  Nonstatutory  Stock
Options.  For purposes of this Section  6(a),  Incentive  Stock Options shall be
taken into account in the order in which they were granted,  and the Fair Market
Value of the Shares shall be determined as of the time of grant.

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

         (c) The  following  limitations  shall  apply to grants of Options  and
Stock Purchase Rights to Employees:

              (i) No  Employee  shall  be  granted,  in any  fiscal  year of the
Company,  Options  and Stock  Purchase  Rights to purchase  more than  3,200,000
Shares (as adjusted automatically for previous stock splits).

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

         (iii) If an Option or Stock Purchase  Right is canceled  (other than in
connection  with a transaction  described in Section 13), the canceled Option or
Stock  Purchase  Right  will be counted  against  the limit set forth in Section
6(c)(i).  For this purpose, if the exercise price of an Option or Stock Purchase
Right is  reduced,  the  transaction  will be treated as a  cancellation  of the
Option or Stock  Purchase  Right and the grant of a new Option or Stock Purchase
Right.

         7. Term of Plan.  The Plan shall  continue in effect until  January 25,
2009, unless terminated earlier under Section 15 of the Plan.  However,  without
further stockholder approval, no Incentive Stock Option may be granted under the
Plan after January 25, 2004.

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

         9. Option Exercise Price and Consideration.

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

              (i) In the case of an Incentive Stock Option

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

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

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

         (b)  Waiting  Period  and  Exercise  Dates.  At the time an  Option  is
granted,  the Administrator  shall fix the period within which the Option may be
exercised and shall determine any conditions  which must be satisfied before the
Option may be  exercised.  In so doing,  the  Administrator  may specify that an
Option may not be exercised until the completion of a service period.

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

              (i) cash;

              (ii) check;

              (iii) promissory note;

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

              (v) delivery of a properly  executed exercise notice together with
such other  documentation as the  Administrator  and the broker,  if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price;

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

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

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

         10. Exercise of Option.

         (a) Procedure for Exercise; Rights as a Stockholder. Any Option granted
hereunder  shall be  exercisable  according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.

         An Option may not be exercised for a fraction of a Share.

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

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

         (b)  Termination  of Employment,  Consulting or Director  Relationship.
Upon termination of an Optionee's  Continuous Status as an Employee,  Consultant
or  Director  (but not in the  event of a change  of  status  from  Employee  to
Consultant or Director (in which case an Employee's Incentive Stock Option shall
automatically  convert to a Nonstatutory Stock Option on the ninety-first (91st)
day  following  such  change  of  status)  or from  Consultant  or  Director  to
Employee),  other than upon the Optionee's death or Disability, the Optionee may
exercise  his or her Option to the extent  that the  Optionee  was  entitled  to
exercise  it at the  date  of  termination  (but  in no  event  later  than  the
expiration  of the term of such Option as set forth in the Notice of Grant).  In
the absence of a specified time in the Notice of Grant,  the Option shall remain
exercisable  for 90 days  following  the  Optionee's  termination  of Continuous
Status as an Employee, Consultant or Director. In the case of an Incentive Stock
Option,  such period of time shall not exceed  ninety (90) days from the date of
termination.  If, at the date of  termination,  the  Optionee is not entitled to
exercise  his or her  entire  Option,  the Shares  covered by the  unexercisable
portion of the Option  shall  revert to the Plan.  If,  after  termination,  the
Optionee  does not exercise his or her Option  within the time  specified by the
Administrator, the Option shall terminate, and the Shares covered by such Option
shall revert to the Plan.

         (c) Disability of Optionee.  In the event that an Optionee's Continuous
Status as an  Employee,  Consultant  or Director  terminates  as a result of the
Optionee's  Disability,  the Optionee may exercise his or her Option at any time
within  twelve (12) months  from the date of such  termination,  but only to the
extent  that  the  Optionee  was  entitled  to  exercise  it at the date of such
termination  (but in no  event  later  than the  expiration  of the term of such
Option as set forth in the Notice of Grant). If, at the date of termination, the
Optionee  is not  entitled  to  exercise  his or her entire  Option,  the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after  termination,  the Optionee does not exercise his or her Option within the
time specified  herein,  the Option shall  terminate,  and the Shares covered by
such Option shall revert to the Plan.

         (d) Death of Optionee.  In the event of the death of an  Optionee,  the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the  expiration  of the term of such Option
as set forth in the Notice of Grant),  by the  Optionee's  estate or by a person
who  acquired the right to exercise  the Option by bequest or  inheritance,  but
only to the extent that the  Optionee was entitled to exercise the Option at the
date of death.  If, at the time of  death,  the  Optionee  was not  entitled  to
exercise  his or her  entire  Option,  the Shares  covered by the  unexercisable
portion of the Option shall immediately revert to the Plan. If, after death, the
Optionee's  estate or a person who  acquired the right to exercise the Option by
bequest or  inheritance  does not exercise the Option within the time  specified
herein, the Option shall terminate,  and the Shares covered by such Option shall
revert to the Plan.

         11. Stock Purchase Rights.

         (a) Rights to  Purchase.  Stock  Purchase  Rights may be issued  either
alone,  in addition  to, or in tandem with other awards  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, by means of a Notice of Grant, of the terms,  conditions and
restrictions  related to the  offer,  including  the  number of Shares  that the
offeree shall be entitled to purchase, the price to be paid, and the time within
which the offeree must accept such offer, which shall in no event exceed six (6)
months  from the date upon which the  Administrator  made the  determination  to
grant the Stock  Purchase  Right.  The offer shall be accepted by execution of a
Restricted Stock Purchase Agreement in the form determined by the Administrator.

         (b) Repurchase Option.  Unless the Administrator  determines otherwise,
the  Restricted  Stock Purchase  Agreement  shall grant the Company a repurchase
option  exercisable  upon  the  voluntary  or  involuntary  termination  of  the
purchaser's  employment  with the  Company  for any reason  (including  death or
Disability).   The  purchase  price  for  Shares  repurchased  pursuant  to  the
Restricted  Stock  purchase  agreement  shall be the original  price paid by the
purchaser and may be paid by cancellation  of any  indebtedness of the purchaser
to the Company.  The repurchase  option shall lapse at a rate  determined by the
Administrator.

         (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.  In
addition, the provisions of Restricted Stock Purchase Agreements need not be the
same with respect to each purchaser.

         (d)  Rights  as  a  Stockholder.  Once  the  Stock  Purchase  Right  is
exercised,  the  purchaser  shall  have  the  rights  equivalent  to  those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized  transfer agent of the Company. No adjustment
will 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 13
of the Plan.

         12. Non-Transferability of Options and Stock Purchase Rights. An Option
or Stock  Purchase  Right  may not be  sold,  pledged,  assigned,  hypothecated,
transferred,  or disposed of in any manner  other than by will or by the laws of
descent  or  distribution  and may be  exercised,  during  the  lifetime  of the
Optionee, only by the Optionee.

         13.  Adjustments Upon Changes in Capitalization,  Dissolution,  Merger,
Asset Sale or Change of Control.

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

              (b)  Dissolution  or  Liquidation.  In the  event of the  proposed
dissolution or liquidation of the Company, to the extent that an Option or Stock
Purchase Right has not been previously exercised,  it will terminate immediately
prior to the  consummation  of such  proposed  action.  The  Board  may,  in the
exercise of its sole  discretion in such  instances,  declare that any Option or
Stock  Purchase  Right shall  terminate as of a date fixed by the Board and give
each Optionee the right to exercise his or her Option or Stock Purchase Right as
to all or any part of the  Optioned  Stock,  including  Shares  as to which  the
Option or Stock Purchase Right would not otherwise be exercisable.

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

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

         15. Amendment and Termination of the Plan.

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

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

              (c) Effect of Amendment or Termination. No amendment,  alteration,
suspension or  termination  of the Plan shall impair the rights of any Optionee,
unless mutually  agreed  otherwise  between the Optionee and the  Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

         16. Conditions Upon Issuance of Shares.

              (a) Legal  Compliance.  Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock  Purchase  Right and the  issuance  and  delivery of such Shares  shall
comply with all relevant provisions of law, including,  without limitation,  the
Securities Act of 1933, as amended,  the Exchange Act, the rules and regulations
promulgated  thereunder,  Applicable  Laws,  and the  requirements  of any stock
exchange or quotation system upon which the Shares may then be listed or quoted,
and shall be further  subject to the  approval of counsel  for the Company  with
respect to such compliance.

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

         17. Liability of Company.

              (a) 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.

              (b)  Grants  Exceeding  Allotted  Shares.  If the  Optioned  Stock
covered by an Option or Stock Purchase  Right exceeds,  as of the date of grant,
the  number of Shares  which may be  issued  under the Plan  without  additional
stockholder  approval,  such Option or Stock  Purchase  Right shall be void with
respect  to such  excess  Optioned  Stock,  unless  stockholder  approval  of an
amendment  sufficiently  increasing  the number of Shares subject to the Plan is
timely obtained in accordance with Section 15(b) of the Plan.

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