APPENDIX A

TERMS OF Performance Restricted Stock Units



|1. | Grant. Sun hereby grants to you under the Plan at the per share price of $0.00067 USD (the Purchase Price), the number of Performance Restricted Stock Units
indicated in the Notice of Grant, subject to all of the terms in this Agreement and the Plan.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Payment of Purchase Price. When Shares are issued to you in payment for the Performance Restricted Stock Units, the Purchase Price will be deemed paid through services
rendered by you (not in cash), and will be subject to the appropriate tax withholdings.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Suns Obligation to Pay. Unless and until the Performance Restricted Stock Units have vested in the manner set forth in paragraphs 4 or 5, you will have no right to
payment of the Performance Restricted Stock Units. Until any vested Performance Restricted Stock Units actually are paid, the Performance Restricted Stock Units will be an unsecured obligation of Sun. Any vested Performance Restricted Stock Units
will be paid in Shares. Only whole Shares will be issued.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Vesting Schedule.
|-- | -----------------



| | (a) | General. Except as otherwise provided in this paragraph 4 and paragraph 5 of this Agreement, and subject to paragraph 7, the Performance Restricted Stock Units are
scheduled to vest in accordance with the vesting schedule shown in the Notice of Grant. Performance Restricted Stock Units scheduled to vest on any date actually will vest only if you continue to be employed by Sun or one of its Subsidiaries through
the applicable vesting date, except to the extent otherwise provided in this Agreement, by Sun in a written agreement between you and an authorized officer of Sun or in accordance with the then-applicable written policies of Sun. In all instances in
which Performance Restricted Stock Units continue to vest after you cease to be employed by Sun or one of its Subsidiaries, the payment of such accelerated Performance Restricted Stock Units nevertheless will be made at the same time or times such
Performance Restricted Stock Units would have been paid had they vested in accordance with the vesting schedule shown in the Notice of Grant.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Leave of Absence. Notwithstanding the above, vesting of the Performance Restricted Stock Units will be suspended
if you take an authorized unpaid leave of absence (including a leave of absence for military, educational, disability or personal purposes, but except as may be required by law) of more than thirty (30) days or an authorized paid leave of
absence of more than ninety (90) days. The vesting schedule shown in the Notice of Grant will be delayed for the number of days that the authorized unpaid leave of absence or authorized paid leave of absence extends beyond the periods set forth
above. The suspension of vesting will commence on the thirty-first (31st) day of an authorized unpaid leave of absence of more than thirty
(30) days or, in the case of an authorized paid leave of absence of more than ninety (90) days, on the ninety-first (91st) day of the leave
and the suspension will end on the earlier of: (i) the last business day preceding the date on
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

which your leave of absence terminates; or (ii) a date twelve (12) months after the beginning
of the leave of absence. These vesting suspension provisions will be applied in compliance with local law. Sun policies on leave of absence may vary outside the United States, in accordance with local law. The preceding two sentences will apply only
to those employees who are not subject to United States taxes.



| | (c) | Disability. Notwithstanding the above, if your employment with Sun (or the employing Subsidiary) terminates as a result of your Disability, during the twelve (12) months
following your termination, you will continue to vest as to the number of Performance Restricted Stock Units that would have vested if you had remained an employee of Sun (or the employing Subsidiary) during that period. For purposes of this
Agreement, Disability means your total and permanent disability as defined in Section 22(e)(3) of the Code.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Death. Notwithstanding the above, if your employment with Sun (or the employing Subsidiary) terminates as a result of your death, the Performance Restricted Stock Units
granted under this Agreement will continue to vest during the twelve (12) months following your death as to the number of Performance Restricted Stock Units that would have vested had you remained an employee of Sun (or the employing
Subsidiary) during that period.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Performance Target. The Performance Target shall be achieved if Sun has Operating Income of at least 4% for the fiscal quarter ended June 30, 2006 and
Revenue of at least $13.4 billion for the fiscal year ended June 30, 2007, as such terms are defined under the Section 162(m) Executive Officer Performance-Based Bonus Plan. The determination of whether or not the Performance Target
is achieved shall be made by the Leadership Development and Compensation Committee of the Board of Directors in its sole discretion as soon as practicable after the end of the fiscal year, and no Shares will be issued until such determination is
made.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. | Committee Discretion. The Committee, in its discretion, may accelerate the vesting of some or all of the Performance Restricted Stock Units at any time, subject to the terms
of the Plan. If so accelerated, the Performance Restricted Stock Units will be considered as having vested as of the date specified by the Committee. If the Committee, in its discretion, accelerates the vesting of any Performance Restricted Stock
Units, the payment of the accelerated Performance Restricted Stock Units nevertheless will be made at the same time or times as if the Performance Restricted Stock Units had vested in accordance with the vesting schedule shown on the Notice of Grant
(whether or not you remain employed by Sun or one of its Subsidiaries).
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | Payment after Vesting. Any Performance Restricted Stock Units that vest while you remain employed by Sun or one of its Subsidiaries in accordance with paragraph 4 will be
paid to you (or in the event of your death, to your estate) in Shares as soon as administratively practicable following the date of vesting, subject to paragraph 9. Any Performance Restricted Stock Units that continue to vest after you cease to
be employed by Sun or one of its Subsidiaries as provided in paragraph 4 or that vest in accordance with paragraph 5 will be paid to you (or in the event of your death, to your estate) in Shares in accordance with the provision of such paragraphs,
subject to paragraph 9. For each Performance Restricted Stock Unit that vests, you will receive one Share.

|7. | Forfeiture. Except as expressly provided herein, any Performance Restricted Stock Units that have not vested at the time you cease to be employed by Sun or one of its
Subsidiaries will be forfeited and automatically transferred to and reacquired by Sun at no cost to Sun.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | Death. Any distribution or delivery to be made to you under this Agreement will, if you are then deceased, be made to the administrator or executor of your estate. The
administrator or executor must furnish Sun with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to Sun to establish the validity of the transfer and compliance with any applicable laws or regulations.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | Withholding of Taxes. Regardless of any action Sun or the company that employs you (the Employer) takes with respect to any or all income tax, social insurance,
payroll tax, payment on account or other tax-related withholding (Tax-Related Items), you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that Sun and/or the
Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the grant of Performance Restricted Stock Units, including the grant, vesting and lapse of repurchase rights,
the subsequent sale of Shares and/or the receipt of any dividends; and (2) do not commit to structure the terms of the grant or any aspect of the grant of Performance Restricted Stock Units to reduce or eliminate your liability for Tax-Related
Items. When the Shares are issued as payment for vested Performance Restricted Stock Units, you will recognize immediate U.S. taxable income if you are a U.S. taxpayer. If you are a non-U.S. taxpayer, you will be subject to applicable taxes in your
jurisdiction. Sun or the Employer is required to withhold from you an amount that is sufficient to pay the minimum federal, state and local income, employment and any other applicable taxes required to be withheld by Sun or the Employer with respect
to the Shares. Sun or the Employer may, in its discretion, meet this withholding requirement in any one or more of the following ways:
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | by withholding or selling a portion of the Shares that otherwise would be paid out for your vested Performance Restricted Stock Units;
| | --- | --------------------------------------------------------------------------------------------------------------------------------------



| | (b) | by withholding the amount necessary to pay the applicable taxes from your paycheck, with no withholding of Shares;
| | --- | ------------------------------------------------------------------------------------------------------------------



| | (c) | by requiring you to make alternate arrangements to meet the withholding obligation; or
| | --- | --------------------------------------------------------------------------------------



| | (d) | such other method as Sun or the Committee may elect in compliance with local law.
| | --- | ---------------------------------------------------------------------------------

No payment of Shares will be made to you (or your estate) for Performance Restricted Stock Units unless and until satisfactory arrangements (as determined by Sun) have been made by you to fulfill Suns (or the
Employers) obligation to withhold or collect any income and other taxes with respect to the Performance Restricted Stock Units. By accepting this grant, you expressly consent to the withholding of Shares and to any additional (or alternative)
cash withholding as provided for in this paragraph 9. All income and other taxes related to the Performance Restricted Stock Unit award and any Shares delivered in payment thereof are your sole responsibility.

|10. | Rights as Stockholder. Neither you nor any person claiming under or through you will have any of the rights or privileges of a stockholder of Sun in respect of any Shares
deliverable hereunder unless and until certificates representing the Shares (which may be in book entry form) have been issued, recorded on the records of Sun or its transfer agents or registrars, and delivered to you (including through electronic
delivery to a brokerage account). Notwithstanding any other part of this Agreement, any quarterly or other regular, periodic dividends or distributions (as determined by Sun) will not affect unvested Performance Restricted Stock Units, and no
dividends or other distributions will be paid on unvested Performance Restricted Stock Units. Notwithstanding any other part of this Agreement, any quarterly or other regular, periodic dividends or distributions (as determined by Sun) paid on Shares
will accrue with respect to Performance Restricted Stock Units that are vested but unpaid pursuant to paragraph 4 or 5, and will be paid out at the same time or time(s) as the underlying Shares on which such dividends or other distributions
have accrued. After the issuance, recordation and delivery of any shares, you will have all the rights of a stockholder of Sun with respect to voting the Shares and receiving dividends and distributions on the Shares.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|11. | Nature of Grant. In accepting the offer to acquire Shares, you acknowledge that: (a) the Plan is established voluntarily by Sun, it is discretionary in nature and it may
be modified, amended, suspended or terminated by Sun at any time, unless otherwise provided in the Plan and this Agreement; (b) the grant of Performance Restricted Stock Units is voluntary and occasional and does not create any contractual or
other right to receive future grants of Performance Restricted Stock Units, or benefits in lieu of such grants even if Performance Restricted Stock Units have been granted repeatedly in the past; (c) all decisions with respect to future
Performance Restricted Stock Unit grants, if any, will be at the sole discretion of Sun; (d) you are voluntarily participating in the Plan; (e) the grant of Performance Restricted Stock Units is an extraordinary item that does not
constitute compensation of any kind for services of any kind rendered to Sun or the Employer, and which is outside the scope of your employment contract, if any; (f) the Performance Restricted Stock Units are not part of normal or expected
compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments;
(g) the future value of the Shares is unknown and cannot be predicted with certainty; (h) in consideration of the grant of Performance Restricted Stock Units, no claim or entitlement to compensation or damages will arise from the
termination of vesting or diminution in value of the Shares resulting from termination of your active employment by Sun or the Employer (for any reason whatsoever and whether or not in breach of contract or local labor laws) and you irrevocably
release Sun and the Employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by signing this Agreement, you will be deemed irrevocably to have
waived your entitlement to pursue such claim; and (i) notwithstanding any terms or conditions of the Plan to the contrary, in the event of involuntary termination of your active employment (whether or not in breach of contract or local labor
laws), your right to continued vesting, if any, will terminate effective as of the date that you are no longer actively employed and will not be extended by any notice period mandated under local law (e.g., active employment would not include a
period of garden leave or similar period pursuant to local law), except as expressly provided herein, and that Sun will have the exclusive discretion to determine when you are no longer actively employed for purposes of administering
your grant of Performance Restricted Stock Units.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

will be freely tradable upon receipt. However, your subsequent sale of the Shares will be subject to any market blackout-period that may be imposed by Sun and must comply with Suns insider trading policies, and any other applicable securities
or other laws.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|15. | Delay in Payment. Notwithstanding any other part of this Agreement, any Performance Restricted Stock Unit otherwise payable to you pursuant to this Agreement will not be paid
during the six-month period following your termination of employment unless Sun determines, in its good faith judgment, that the payment would not cause you to incur an additional tax under Section 409A of the Code and any temporary or final
Treasury Regulations and Internal Revenue Service guidance thereunder (Section 409A). If the payment of any amounts are delayed as a result of the previous sentence, any Performance Restricted Stock Unit otherwise payable to you during
the six (6) months following your termination will accrue during such six-month period and will become payable in Shares on the date six (6) months and one (1) day following the date of your termination.

is listed; and (b) the completion of any registration or other qualification of the Shares under any U.S. state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory
body, which the Committee shall, in its absolute discretion, deem necessary or advisable; and (c) the obtaining of any approval or other clearance from any U.S. state or federal governmental agency or any

further joint election forms as may be required between you and any successor to Sun and/or your Employer. If you do not execute and deliver a joint election form to Sun or your Employer prior to the first vesting of your Performance Restricted
