or any aspect of the RSUs that cannot be satisfied by any of the means described in the preceding paragraph. Sun may refuse to deliver shares of Stock to you if you fail to meet your obligations for the Tax-Related Items, as described in this
section.

APPENDIX A

ADDITIONAL TERMS AND CONDITIONS OF THE

SUN MICROSYSTEMS, INC. 2007 OMNIBUS INCENTIVE PLAN

RESTRICTED STOCK UNIT AGREEMENT

FOR NON U.S.-EMPLOYEES

This Appendix A includes additional terms and conditions that govern the RSUs granted to you under the Plan if you
reside in one of the countries listed below. Capitalized terms used but not defined in this Appendix A are defined in the Plan and/or the Award Agreement, and have the meanings set forth therein.

This Appendix A also includes information regarding exchange controls and certain other issues of which you should be aware with respect to your participation in the
Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of July 1, 2008. Such laws are often complex and change frequently. As a result, Sun strongly recommends that you not
rely on the information noted in this Appendix A as the only source of information relating to the consequences of your participation in the Plan because the information may be out of date at the time that you vest in the RSUs or sell shares of
Stock acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to your particular situation, and Sun
is not in a position to assure you of a particular result. Accordingly, you are advised to seek appropriate professional advice as to how the relevant laws in your country may apply to your situation.

Finally, if you are a citizen or resident of a country other than the one in which you are currently working, the information contained herein may not be applicable to
you.

UNITED KINGDOM

RSUs
Payable Only in Shares. Notwithstanding any discretion in the Plan or anything to the contrary in the Award Agreement, the grant of RSUs does not provide any right for you to receive a cash payment and the RSUs are payable in shares of Stock
only.

Withholding Taxes. This provision supplements the Withholding Taxes section of the Award Agreement:

If payment or withholding of the Tax-Related Items (including the Employers Liability, as defined below) is not made within 90 days of the event giving rise to the
Tax-Related Items (the Due Date) or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003, the amount of any uncollected Tax-Related Items will constitute a loan owed by you to the
Employer, effective on the Due Date. You agree that the loan will bear interest at the then-current Official Rate of Her Majestys Revenue and Customs

---

(HMRC), it will be immediately due and repayable, and Sun or the Employer may recover it at any time thereafter by any of the means referred to
in the Withholding Taxes section of the Award Agreement. Notwithstanding the foregoing, if you are a director or executive officer of Sun (within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), you
will not be eligible for such a loan to cover the Tax-Related Items. In the event that you are a director or executive officer and the Tax-Related Items are not collected from or paid by you by the Due Date, the amount of any uncollected Tax-Related
Items will constitute a benefit to you on which additional income tax and national insurance contributions (including the Employers Liability, as defined below) will be payable. You will be responsible for reporting and paying any income tax
and national insurance contributions (including the Employers Liability, as defined below) due on this additional benefit directly to HMRC under the self-assessment regime.

Joint Election. As a condition of your participation in the Plan and the vesting of the RSUs, you agree to accept any liability for secondary Class 1 national insurance contributions (the Employers
Liability) which may be payable by Sun and/or the Employer in connection with the RSUs and any event giving rise to Tax-Related Items. To accomplish the foregoing, you agree to execute the following joint election with Sun (the
Election), the form of such Election being formally approved by HMRC, and any other consent or elections required to accomplish the transfer of the Employers Liability to you. You further agree to execute such other joint elections
as may be required between yourself and any successor to Sun and/or the Employer. If you do not enter into the Election when you accept the Award Agreement, or if the Election is revoked at any time by HMRC, the RSUs will cease vesting and
become null and void, and no shares of Stock will be acquired under the Plan, without any liability to Sun, the Employer and/or any Affiliate. You further agree that Sun and/or the Employer may collect the Employers Liability by
any of the means set forth in the Withholding Taxes section of the Award Agreement.

SUN MICROSYSTEMS, INC.

2007 OMNIBUS INCENTIVE PLAN

Important Note on the Joint Election to Transfer Employer NICs

If you are resident and ordinarily resident in the UK on the date of grant of the restricted stock units (the RSUs), you are required to
enter into a joint election to transfer to you any liability for employer national insurance contributions (the Employers Liability) that may arise in connection with the RSUs granted to you, or in connection with future restricted
stock units granted to you, by Sun Microsystems, Inc. (Sun) under the Sun Microsystems, Inc. 2007 Omnibus Incentive Plan (the Election).

If you do not agree to enter into the Election, the RSUs will be worthless, as (under the terms of the Award Agreement), you will not be able to vest in the RSUs or receive any benefit in connection with the RSUs.

By entering into the Election:



| |  |  | you agree that any Employers Liability that may arise in connection with or pursuant to the vesting of the RSUs (and the acquisition of shares of Stock) or
other taxable events in connection with the RSUs will be transferred to you; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | you authorise Sun and/or your employer to recover an amount sufficient to cover this liability by any method set forth in the Award Agreement and/or the Election
including, but not limited to, withholding from your wages or other cash compensation payable to you by Sun and/or your employer.
