            ("[*] DECISION NOTICE") as soon as practicable, but in any event no

            but in no event later than [*] from the end of the Compliance
            Period.

            If in the [*] Decision Notice, Customer elects to not bring the [*]

subject to limitations imposed by Section 423 of the Code or as otherwise

total combined voting power or value of all classes of stock of the Company or

      SECTION 6. Election to Participate.

      Pursuant to procedures set forth by the Committee, Participants may elect
to participate in a given Offering Period under the Plan prior to the Enrollment

      SECTION 7. Offering Periods; Grant of Option on Enrollment; Purchase of
Shares.

      (a)   The Plan shall be implemented by consecutive, overlapping Offering
Periods with a new Offering Period commencing on a date determined by the
Committee. The first Offering Period and Purchase Period shall begin on June 14,
2004 and end on November 19, 2004. The next Offering Period and Purchase Period
shall begin on November 20, 2004 and end on May 19, 2005. The timing of any
subsequent Offering Periods and Purchase Periods shall be determined by the
Committee.

      (b)   With respect to an Offering Period, each Participant enrolled in
such Offering Period shall be granted as of the Enrollment Date an Option to
purchase on each Purchase Date during the Offering Period a number of Shares
equal to the lesser of (i) the Maximum Share Amount, (ii) $25,000 divided by the
Fair Market Value of the Common Stock on the Enrollment Date, or (iii) the
number determined by dividing (A) the amount accumulated in such Participant's

      (c)   In the event that the Committee determines that the number of Shares
that may be purchased on a Purchase Date may exceed the number of Shares
available under Section 3, the Committee may in its discretion provide for a pro
rata purchase on the Purchase Date, and may continue or terminate any Offering
Periods then in effect.

      SECTION 8. Payment of Purchase Price; Changes in Payroll Deductions;
Issuance of Shares.

      (a)   Payroll deductions shall be made on each day that a Participant is
paid during an Offering Period in respect of a payroll period with a payment
date commencing after the Enrollment Date. The deductions shall be made as a
percentage of the

                                       4
<PAGE>

Participant's Compensation in 1% increments, from 1% to 10% of such
Participant's Compensation, as elected by the Participant; provided that, in
accordance with Section 423(b)(8) of the Code, no Participant shall be permitted
to accrue rights to purchase Shares under this Plan (and any other employee
stock purchase plan of the Company or any of its Subsidiaries) with an aggregate
Fair Market Value (as determined as of the date the applicable option is
granted) in excess of $25,000 for each calendar year in which such option is
outstanding at any time.

      (b)   A Participant may discontinue his or her participation in the Plan
as provided in Section 9, or may change the rate of his or her payroll
deductions during an Offering Period by completing and filing with the Company a
new authorization for payroll deduction, subject to clause (a) above. The
Committee may, in its discretion, limit the number of participation rate changes
in any Offering Period. The change in rate shall be effective as soon as
administratively feasible following the Company's receipt of the new
authorization.

      (c)   All payroll deductions made with respect to a Participant shall be
credited to the Participant's Payroll Deduction Account under the Plan and shall
be deposited with the general funds of the Company, and no interest shall accrue
on the amounts credited to such Payroll Deduction Account, in either case except
as otherwise required by law or as determined by the Committee. All payroll
deductions received or held by the Company may be used by the Company for any
corporate purpose and the Company shall not be obligated to segregate such
payroll deductions, except as otherwise required by law or as determined by the
Committee. Except to the extent provided by the Committee, a Participant may not
make any separate cash payments into such Participant's Payroll Deduction
Account, and payment for Shares purchased under the Plan may not be made in any
form other than by payroll deduction.

      (d)   On each Purchase Date, all funds then in the Participant's Payroll
Deduction Account shall be applied to purchase Shares (or fractions thereof)
pursuant to the automatic exercise of the Option granted on the Enrollment Date.
The Committee may determine with respect to all Participants that any fractional
shares shall be rounded down to the next lower whole share, in which event the
resulting unused amount in any Participant's Payroll Deduction Account may be
carried over into the next Purchase Period.

      (e)   Certificates representing the Shares purchased by a Participant
under the Plan shall be issued to the Participant as soon as practicable
following the end of each Purchase Period, except that the Committee may
determine that such Shares shall be held for each Participant's benefit by a
broker designated by the Committee.

      (f)   The Participant shall have no interest or voting right in the Shares
covered by the Participant's Option until such Option is exercised and the
covered Shares are registered in the name of the Participant.

                                       5
<PAGE>

      SECTION 9. Withdrawal.

      Each Participant may withdraw from participation prior to the end of an
Offering Period or from the Plan in accordance with procedures set forth by the
Committee. Upon a Participant's withdrawal from participation in respect of any
Offering Period or from the Plan, all accumulated payroll deductions in the
Payroll Deduction Account shall be returned, without interest, to such
Participant (except as otherwise required by law or as determined by the
Committee), and such Participant shall not be entitled to any Shares on the
Purchase Date or thereafter with respect to the Offering Period in effect at the
time of such withdrawal. If a Participant withdraws from an Offering Period,
payroll deductions will not resume at the beginning of the succeeding Offering
Period unless the Participant re-enrolls in the Plan in accordance with
procedures set forth by the Committee prior to the applicable Enrollment Date.

      SECTION 10. Termination of Employment.

      A Participant shall cease to participate in the Plan upon the
Participant's termination of employment for any reason (including death), and
all accumulated payroll deductions in the Payroll Deduction Account shall be
returned, without interest, to such Participant. For purposes of the Plan,
transfers from the Company or a Participating Subsidiary to another
Participating Subsidiary or to the Company, as the case may be, shall not be a
termination of employment. Employment shall not be deemed to terminate when the
Participant goes on a leave of absence approved by the Company in writing,
unless otherwise required by the Code and the applicable regulations.

      SECTION 11. Automatic Transfer to Low Price Offering Period.

      To the extent permitted by any applicable laws and regulations, if the
Fair Market Value of the Shares on any Purchase Date in an Offering Period is
lower than the Fair Market Value of the Shares on the Enrollment Date of such
Offering Period, then all Participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the purchase
of their Shares on such Purchase Date and automatically re-enrolled in a new
Offering Period as of the first business day after such Purchase Date.

      Notwithstanding any other provisions in the Plan to the contrary, the
following provisions shall apply to all Options granted under the Plan:

      (a)   In the event of any 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, the Committee shall, in such
manner as it may deem equitable, adjust any or all of (i) the number or type of

      (b)   In the event of a Corporate Transaction, unless each outstanding
Option shall be continued or assumed or an equivalent option substituted by the
Company or the successor corporation or a parent or Subsidiary of the successor
corporation, the Committee shall shorten any Offering Period then in progress by
setting a New Purchase Date, which shall be before the date of the consummation
of the Corporate Transaction. The Committee shall notify each Participant not
less than 10 days prior to the New Purchase Date that (i) a New Purchase Date
has been set and (ii) the Participant's Option will be exercised automatically
on the New Purchase Date unless prior to such date the Participant has withdrawn
from the Offering Period as provided in Section 9. Each Offering Period then in
effect shall terminate on such New Purchase Date.

      SECTION 13. Nontransferability.

      Unless otherwise determined by the Committee, Options granted under the
Plan shall not be transferable or assignable by the Participant other than by
will or by the laws of descent and distribution.

      SECTION 14. Legal Compliance.

      Shares shall not be issued hereunder unless the issuance and delivery of
such Shares shall comply with all applicable laws and regulations, including the
federal and state securities laws and the regulations of any stock exchange or
other securities market on which the Company's securities are traded.

      SECTION 15. No Right to Employment.

      The granting of an Option under the Plan shall impose no obligation on the
Company or any Subsidiary to continue the employment of a Participant and shall
not lessen or affect the Company's or Subsidiary's right to terminate the
employment of such Participant.

      SECTION 16. Amendment or Termination of the Plan.

      (a)   The Plan shall continue until the earliest to occur of the
following: (i) termination of the Plan by the Board, (ii) issuance of all of the
Shares reserved for issuance under the Plan or (iii) the twentieth anniversary
of the effective date of the Plan.

      (b)   The Committee may amend, alter or discontinue the Plan or any
portion thereof at any time, provided that no amendment, alteration or
discontinuation shall be made (x) without the approval of the stockholders of
the Company if such amendment, alteration or discontinuation would (except as is
provided in Section 12) increase the total number of Shares reserved for
purposes of the Plan or as otherwise required by applicable laws or regulations,
or (y) without the consent of a Participant if such amendment, alteration or
discontinuation would materially diminish any of the rights or obligations under
any Option theretofore granted to such Participant under the Plan (except as
otherwise provided in this Section 16).

      (c)   Notwithstanding clause (y) of Section 16(b), the Committee may amend
or terminate the Plan, including with respect to any Offering Periods then in
effect, without consent of the Participants in such manner as it deems necessary
to permit the granting of Options meeting the requirements of the Code or other
applicable laws or in the event the Board determines that the ongoing operation
of the Plan may result in unfavorable financial accounting consequences for the
Company.

      (d)   Notwithstanding clause (y) of Section 16(b), the Committee shall
have the power at any time to change the duration and timing of current and
future Offering Periods and Purchase Periods; provided that in no event shall
any such Offering Period be longer than 27 months.

      SECTION 17. Taxes.

      At the time the Shares are purchased, or at the time some or all of the
Shares issued under the Plan are disposed of, the Participant must make adequate
provision for the Company's federal, state or other tax withholding obligations,
if any, which arise. At any time, the Company, may, but shall not be obligated
to, withhold from the Participant's compensation the amount necessary for the
Company to meet applicable withholding obligations, including any withholding
required to make available to the Company any tax deductions or benefits
attributable to sale or early disposition of Shares by the Participant.

      SECTION 18. Governing Law.

      The Plan shall be governed by and construed in accordance with the laws of
the State of Delaware, without regard to conflicts of laws.

      SECTION 19. Effectiveness of the Plan.
