Dear :



Sun Microsystems, Inc. (the Company), considers it essential to
the best interests of its stockholders to attract top executives and to foster the continuous employment of key management personnel. In this connection, the Board of Directors of the Company (the Board) recognizes that the possibility
of a change of control may exist and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its
stockholders.



The Board has determined that appropriate steps
should be taken to ensure the continuity of management and to foster objectivity in the face of potentially disturbing circumstances arising from the possibility of a change of control of the Company, although no such change is now contemplated. In
order to induce you to remain in the employ of the Company and in consideration of your further services to the Company, the Company agrees that effective as of
 you shall receive the severance benefits set forth in this letter agreement (Agreement) in the event your
employment with the Company terminates subsequent to a Change of Control of the Company (as defined in Section 2(d) hereof) under the circumstances described below.



|1. |  | Term of Agreement. This Agreement shall commence on the date hereof and shall continue in effect until the earlier of (i) the termination of your employment with the Company
other than within twelve (12) months of a Change of Control; (ii) such time as you no longer are a Corporate Executive Officer of the Company (and thereby no longer a member of the Executive Management Group) other than within twelve (12) months of
a Change of Control; (iii) once the Company has satisfied all of its obligations under this Agreement; or (iv) the execution of a written agreement between the Company and you terminating this Agreement.
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | or unvested, shall immediately have their vesting accelerated upon such termination, and all such outstanding stock options (whether incentive stock options (as defined under
Section 422 of the Code) or nonstatutory stock options (i.e., options that are not incentive stock options)) shall be exercisable for a period of three (3) months after such termination.
| |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c) |  | Any cash payment to you under subsection (a) shall be made within 10 calendar days of your termination of employment; provided, however, no Severance Payment shall be made to you

employment is terminated for any reason after twelve (12) months following a Change in Control.
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. |  | Parachute Payments. In the event that any payment or benefit received or to be received by you in connection with a termination of your employment with the Company
(collectively, the Payments) would (i) constitute a parachute payment within the meaning of Section 280G of the Code or any similar or successor provision to 280G and (ii) but for this Section 4, be subject to the excise tax imposed by
Section 4999 of the Code or any similar or successor provision to Section 4999 (the Excise Tax), then such Payments (which Payments shall collectively be referred to herein as the Severance Parachute Payments) shall be
reduced to the largest amount which would result in no portion of the Severance Parachute Payments being subject to the Excise Tax. In the event any reduction of benefits is required pursuant to this Agreement, you shall be allowed to choose which
benefits hereunder are reduced (e.g., reduction first from the Severance Payment, then from the vesting acceleration). Any determination as to whether a reduction is required under this Agreement and as to the amount of such reduction shall be made
in writing by the Companys independent public accountants (the Accountants) prior to the Change of Control, whose determinations shall be conclusive and binding upon you and the Company for all purposes. If the Internal Revenue
Service (the IRS) determines that a Severance Parachute Payment is subject to the Excise Tax, then the Company or any related corporation, as their exclusive remedy, shall seek to enforce the provisions of Section 5 hereof. Such
enforcement of Section 5 hereof shall be the only remedy, under any and all applicable state and federal laws or otherwise, for your failure
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | to reduce the Severance Parachute Payments so that no portion thereof is subject to the Excise Tax. The Company or related corporation shall reduce a Severance Parachute Payment in
accordance with Section 4 only upon written notice by the Accountants indicating the amount of such reduction, if any. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this
Agreement.
| |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. |  | Remedy. If, notwithstanding the reduction described in Section 4 hereof, the IRS determines that you are liable for the Excise Tax as a result of the receipt of a Severance
Parachute Payment, then you shall, subject to the provisions of this Agreement, be obligated to pay to the Company (the Repayment Obligation) an amount of money equal to the Repayment Amount (defined below). The Repayment
Amount with respect to a Severance Parachute Payment shall be the smallest such amount, if any, as shall be required to be paid to the Company so that your net proceeds with respect to any Severance Parachute Payment (after taking into account
the payment of the Excise Tax imposed on such Severance Parachute Payment) shall be maximized. Notwithstanding the foregoing, the Repayment Amount with respect to a Severance Parachute Payment shall be zero if a Repayment Amount of more than zero
would not eliminate the Excise Tax imposed on such Severance Parachute Payment. If the Excise Tax is not eliminated through the performance of the Repayment Obligation, you shall pay the Excise Tax. The Repayment Obligation shall be performed within
thirty (30) days of either (i) your entering into a binding agreement with the IRS as to the amount of your Excise Tax liability or (ii) a final determination by the IRS or a decision by a court of competent jurisdiction requiring you to pay the
Excise Tax with respect to such a Severance Parachute Payment from which no appeal is available or is timely taken.
|-- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. |  | No Mitigation. You shall not be required to mitigate the amount of any payment provided for in Section 3 hereof by seeking other employment or otherwise, nor shall the amount
of such payment be reduced by reason of compensation or other income you receive for services rendered after your termination of employment with the Company.
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. |  | Exclusive Remedy. In the event of a termination of your employment within twelve (12) months following a Change of Control, the provisions of Section 3 are intended to be and
are exclusive and in lieu of any other rights or remedies to which you or the Company may otherwise be entitled (including any contrary provisions in any employment agreement you may have with the Company), whether at law, tort or contract, in
equity, or under this Agreement. You shall not be entitled to any severance benefits, compensation or other payments or rights upon termination of employment within twelve (12) months following a Change of Control other than those benefits expressly
set forth in Section 3.
