Section 162(m).  To the extent
that the Administrator determines it to be desirable to qualify Options granted

to qualify transactions hereunder as exempt under Rule 16b-3, the transactions

Committee, which committee shall be constituted to satisfy Applicable Laws.

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

(i)
to determine the Fair Market Value;

(ii)
to select the Service Providers to whom Options, Restricted Stock Units and
Stock Purchase Rights may be granted hereunder;

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

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

(v)
to determine the terms and conditions, not inconsistent with the terms of the
Plan, of any Option, Restricted Stock Unit 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 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,
Restricted Stock Unit 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;

(vi)
to institute an Option Exchange Program subject to shareholder approval;

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

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

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

(xii)
to correct any defect, supply any omission, or reconcile any inconsistency in
the Plan, or in any Option Agreement, Restricted Stock Unit Agreement or
Restricted Stock Purchase Agreement, in a manner and to the extent it shall
deem necessary, all of which determinations and interpretations made by the
Administrator shall be conclusive and binding on all Optionees, any other
holders of Options and on their legal representatives and beneficiaries; and

(xiii)
except to the extent prohibited by, or impermissible in order to obtain
treatment desired by the Administrator under, applicable law or rule, to
allocate or delegate all or any portion of its powers and responsibilities to
any one or more of its members or to any person(s) selected by it, subject to
revocation or modification by the Administrator of such allocation or
delegation.

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,
Restricted Stock Units or Stock Purchase Rights.

5. Eligibility.
 Nonstatutory Stock Options, Restricted Stock
Units and Stock Purchase Rights may be granted to Service Providers.  Incentive Stock Options may be granted only
to Employees.

6. Limitations.

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

7

---



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

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

(i)
No Service Provider shall be granted, in any fiscal year of the Company,
Options to purchase more than 750,000 Shares.

(ii)
In connection with his or her initial service, a Service Provider may be
granted Options to purchase up to an additional 2,000,000 Shares, which shall
not count against the limit set forth in subsection (i) above.

(iii)
The foregoing limitations shall be adjusted proportionately in connection with
any change in the Companys capitalization as described in Section 14.

(iv)
If an Option is cancelled in the same fiscal year of the Company in which it
was granted (other than in connection with a transaction described in Section
14), the cancelled Option will be counted against the limits set forth in
subsections (i) and (ii) above. For this purpose, if the exercise price of an
Option is reduced, the transaction will be treated as a cancellation of the
Option and the grant of a new Option.

7.
Term of Plan. Subject to Section
20 of the Plan, the Plan shall become effective upon its adoption by the Board.
It shall continue in effect for a term of ten (10) years unless terminated
earlier under Section 16 of the Plan.

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

9.

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

---



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

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

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

(b)
Waiting Period and Exercise Dates. At the time an Option is granted, the
Administrator shall fix the period within which the Option may be exercised and
shall determine any conditions that must be satisfied before the Option may be
exercised.

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

(i)
cash;

(ii)
check;

(iii)
promissory note;

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

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

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

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

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. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be suspended during any unpaid leave
of absence. An Option may not be exercised for a fraction of a Share.

An
Option shall be deemed exercised when the Company receives: (i) written or
electronic notice of exercise (in accordance with the Option Agreement) from
the person entitled to exercise the Option, and (ii) full payment for the
Shares with respect to which the Option is exercised. Full payment may consist
of any consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse or in the name of a
family trust of which the Optionee is a trustee. Until the Shares are issued
(as evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a stockholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option. The Company shall
issue (or cause to be issued) such Shares promptly after the Option is
exercised; provided that if the Company shall be advised by counsel that
certain requirements under the Federal, state or foreign securities laws must
be met before Shares may be issued under this Plan, the Company shall notify
all persons who have been issued Options, and the Company shall have no
liability for failure to issue Shares under any exercise of Options because of
delay while such requirements are being met or the inability of the Company to
comply with such requirements. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are
issued, except as provided in Section 14 of the Plan.

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

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

(c)
Disability of Optionee. If an Optionee ceases to be a Service Provider
as a result of the Optionees Disability, the Optionee may exercise his or her
Option within such period

10

---



of time as is
specified in the Option Agreement to the extent the Option is vested on the
date of termination (but in no event later than the expiration of the term of
such Option as set forth in the Option Agreement). In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for
twelve (12) months following the Optionees termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered
by such Option shall revert to the Plan.

(d)
Death of Optionee. If an Optionee dies while a Service Provider, the
Option may be exercised following the Optionees death within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of death (but in no event may the Option be exercised later
than the expiration of the term of such Option as set forth in the Option
Agreement), by the Optionees designated beneficiary, provided such beneficiary
has been designated prior to the Optionees death in a form acceptable to the
Administrator. If no such beneficiary has been designated by the Optionee, then
such Option may be exercised by the personal representative of the Optionees
estate or by the person(s) to whom the Option is transferred pursuant to the
Optionees will or in accordance with the laws of descent and distribution. In
the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for twelve (12) months following the Optionees death. If,
at the time of death, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

11. 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 or electronically, 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. 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
service 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.

(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 14 of the
Plan.

12. Restricted Stock Units. The Administrator is authorized to make awards
of Restricted Stock Units to any Service Provider selected by the Administrator
in such amounts and subject to such terms and conditions as determined by the
Administrator. At the time of grant, the Administrator shall specify the date
or dates on which the Restricted Stock Units shall become fully vested and
nonforfeitable, and may specify such conditions to vesting as it deems appropriate.
At the time of grant, the Administrator shall specify the maturity date
applicable to each grant of Restricted Stock Units which shall be no earlier
than the vesting date or dates of the Restricted Stock Units and may be
determined at the election of the grantee. On the maturity date, the Company
shall, subject to Section 17, transfer to the Participant one unrestricted,
fully transferable share of Common Stock for each Restricted Stock Unit
scheduled to be paid out on such date and not previously forfeited. The
Restricted Stock Unit Agreement shall contain such terms, provisions and
conditions as may be determined by the Administrator in its sole discretion.

13. Transferability of Options, Restricted Stock Units and Stock Purchase
Rights. Unless determined otherwise by the Administrator, an Option, Restricted
Stock Unit 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. If the Administrator makes an
Option, Restricted Stock Unit or Stock Purchase Right transferable, such
Option, Restricted Stock Unit or Stock Purchase Right shall contain such
additional terms and conditions as the Administrator deems appropriate.

14. Adjustments; Dissolution; Merger or Change in Control.

(a)
Adjustments. In the event that any dividend or other distribution,
reorganization, merger, consolidation, combination, repurchase, or exchange of
Common Stock or other securities of the Company, or other change in the
corporate structure of the Company affecting the Common Stock (other than an
Equity Restructuring) occurs such that an adjustment is determined by the
Administrator (in its sole discretion) to be appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan, then the Administrator shall, in such manner as
it may deem equitable, adjust the number and class of Common Stock which may be
delivered under the Plan, the purchase price per Share and the number of Shares
covered by each Option which has not yet been exercised and each Restricted
Stock Unit for wich a Share has not yet been issued, and the numerical limits
of Sections 3 and 6.

(b)
Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Administrator shall notify each Optionee as
soon as practicable prior to the effective date of such proposed transaction.
The Administrator in its discretion may provide for an Optionee to have the
right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares
as to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any

12

---



Company
repurchase option applicable to any Shares purchased upon exercise of an Option
or Stock Purchase Right shall lapse as to all such Shares and that the vesting
with respect to Restricted Stock Units shall fully accelerate, provided the
proposed dissolution or liquidation takes place at the time and in the manner
contemplated. To the extent an Option or Stock Purchase Right has not been
previously exercised or Shares subject to a Restricted Stock Unit have not been
previously issued, such Option, Restricted Stock Unit or Stock Purchase Right
will terminate immediately prior to the consummation of such proposed action.

(c)
In connection with the occurrence of any Equity Restructuring, and
notwithstanding anything to the contrary in Section 14(a) and 14(b):

(i)
The number and type of securities subject to each outstanding Option,
Restricted Stock Unit or Stock Purchase Right and the exercise price or grant
price thereof, if applicable, will be proportionately adjusted. The adjustments
provided under this Section 14(c)(i) shall be nondiscretionary and shall be
final and binding on the affected Service Provider and the Company.

(ii)
The Administrator shall make such proportionate adjustments, if any, as the
Administrator in its discretion may deem appropriate to reflect such Equity
Restructuring with respect to the aggregate number and kind of shares that may
be issued under the Plan (including, but not limited to, adjustments of the
limitations in Sections 3 and 6).

(iii)
Notwithstanding anything in this Section 14 to the contrary, this Section 14(c)
shall not apply to, and instead Section 14(a) shall apply to, any Option to
which the application of this Section 14(c) would (A) result in a penalty tax
under Section 409A of the Code and the Department of Treasury proposed and
final regulations and guidance thereunder or (B) cause any Incentive Stock
Option to fail to qualify as an incentive stock option under Section 422 of
the Code.

(d)
Merger or Change in Control. In the event of a merger of the Company
with or into another corporation, or a Change in Control, each outstanding
Option, Restricted Stock Unit and Stock Purchase Right shall be assumed or an
equivalent option or right substituted by the successor corporation or a Parent
or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option, Restricted Stock
Unit or Stock Purchase Right, the Optionee shall fully vest in and have the
right to exercise the Option or Stock Purchase Right and to have Shares issued
pursuant to the Restricted Stock Unit, in each case, as to all of the Optioned
Stock, including Shares as to which it would not otherwise be vested or
exercisable. If an Option or Stock Purchase Right becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger or
Change in Control, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully vested
and exercisable for a period of fifteen (15) days from the date of such notice,
and the Option or Stock Purchase Right shall terminate upon the expiration of
such period. If a Restricted Stock Unit becomes fully vested in lieu of assumption
or substitution in the event of a merger or Change in Control, the Share
subject to such Restricted Stock Unit shall be issued no later than immediately
prior to the consummation of such merger or Change in Control.

For
the purposes of this subsection (c), the Option, Restricted Stock Unit or Stock
Purchase Right shall be considered assumed if, following the merger or Change
in Control, the option, unit or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option, Restricted Stock Unit
or Stock Purchase Right immediately prior to the merger or Change in Control,
the consideration (whether stock, cash, or other securities or property)
received in the merger or Change in Control 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 Change in Control is not solely
common stock of the successor corporation or its Parent, the Administrator may,
with the consent of the successor corporation, provide for the consideration to
be received upon the exercise of the Option or Stock Purchase Right and upon
the maturity of the Restricted Stock Unit, for each Share of Optioned Stock
subject to the Option, Restricted Stock Unit 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 Change in Control.

15.
Date of Grant. The date of grant of an Option, Restricted Stock Unit or
Stock Purchase Right shall be, for all purposes, the date on which the
Administrator makes the determination granting such Option, Restricted Stock
Unit 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.

16.
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.
Termination of the Plan shall not affect the Administrators ability to
exercise the powers granted to it hereunder with respect to Options, Restricted
Stock Units and Stock Purchase Rights granted under the Plan prior to the date
of such termination.

17.
Conditions Upon Issuance of Shares.

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

(b)
Investment Representations. As a condition to the exercise of an Option
or Stock Purchase Right or the issuance of Shares pursuant to a Restricted
Stock Unit, the Company

14

---



may require
the person exercising such Option, Restricted Stock Unit 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.

18. 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.

19. 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.

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