[address]

Dear [name]:

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 [date], you shall receive the severance benefits from the Company, set forth in this letter
agreement (Agreement) in the event you Separate from Service with the Company and all related entities (collectively, Sun) subsequent to a Change of Control of the Company (as defined in Section 2(d) hereof) under the
circumstances described below. This Agreement supersedes and replaces prior agreements and/or policies related to severance benefits payable to you following a Change of Control of the Company (including the letter agreement between you and the
Company dated , 200_ as specified in Section 11 of such agreement).

1. Term of Agreement. This Agreement shall commence on the date hereof and shall continue in effect until the earlier of (i) your Separation from Service other than within twelve (12) months of a

| | Notwithstanding anything contained in subsections (a) and (b) above, the Company shall have no obligation to make any payment or offer any benefits
to you under this Section 3 if you Separate from Service prior to a Change in Control or if you Separate from Service within twelve (12) months after a Change in Control for Cause, death, Disability, retirement or voluntary resignation
other than for Good Reason or if you Separate from Service 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 your Separation from Service with the Company (collectively, the Severance Parachute 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 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 independent public accountants appointed for this purpose by the Company (the
Accountants) prior to, or immediately following, 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
the Severance Parachute Payments are 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 below 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
the Severance Parachute Payments in accordance with this 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 the Severance Parachute Payments 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 Payments (after taking into account the payment of the Excise Tax imposed on such Severance Parachute Payments) shall be maximized. Notwithstanding the foregoing, the Repayment Amount with respect
to the Severance Parachute Payments 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 the Severance Parachute Payments 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 Separation from Service from the Company.

7. Exclusive Remedy. In the event of your Separation from Service on account of an involuntary termination without Cause or a voluntary termination for Good Reason 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.
