Exhibit 10.12

SUN MICROSYSTEMS, INC.

U.S. VICE PRESIDENT SEVERANCE PLAN

AND

SUMMARY PLAN DESCRIPTION

Purpose of Plan

The Sun Microsystems, Inc.
U.S. Vice President Severance Plan (the Plan) provides Notification Pay and Severance Benefits if your employment terminates because of a Retirement or Mutual Agreement (defined below). However, this Plan does not provide benefits if you
voluntarily terminate employment prior to qualifying for Retirement or if you are involuntarily terminated with or without Cause. You must sign, and not revoke, a Release and Waiver Agreement in order to receive Severance Benefits.

This Plan was originally adopted effective July 1, 2005. It was restated effective November 1, 2005. It is now restated again effective May 1, 2006. In
this document Sun means Sun Microsystems, Inc., its subsidiaries and its successor or successors. The Plan is intended to comply with Section 409A of the Internal Revenue Code and from its original effective date, the Plan has been
operated in accordance with a good faith, reasonable interpretation of Section 409A of the Internal Revenue Code.

This document constitutes both the
official plan document and the required summary plan description under ERISA.

Highlights

Under this Plan, you are eligible to receive two types of benefits: Notification Pay and Severance Benefits.

Notification Payconsists of either a period of time you remain on Suns payroll or a lump sum payment. You need not sign a Release and Waiver
Agreement in order to receive Notification Pay.

Severance Benefits consist of a lump sum Severance Payment and payment of COBRA
Premiums (if eligible). You will not receive Severance Benefits if you do not sign a Release and Waiver Agreement, or if you sign a Release and Waiver Agreement but revoke it within the seven (7) calendar day revocation period.

The amount of Severance Benefits available to you depends on whether you are a member of Suns Executive Leadership Team (ELT) or a Vice President who
is not a member of the ELT.

Eligibility

You
are an Eligible Employee under the Plan if you are:



| |  |  | A regular full-time or part-time Sun employee on the U.S. Payroll;
| | - |  | ------------------------------------------------------------------



---

| |  |  | Not on the payroll of, or considered an employee of, any Sun subsidiary outside the U.S.;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Employed at the Vice President level or above; and
| | - |  | --------------------------------------------------



| |  |  | Not a Contingent Worker or Partner Worker (includes independent contractor, consultant or vendor) as defined in Suns Headcount Policy.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------

If Sun has not classified you as an employee on the date your service with Sun is terminated and, for that reason, has not withheld employment taxes with respect to you,
and you are later determined retroactively to have been a common-law employee of Sun, whether by Sun, a governmental agency or a court, you will nevertheless be ineligible to receive Plan benefits.

Notwithstanding any other provision of the Plan to the contrary, if you were a Storage Technology Corporation (StorageTek) employee who received severance
benefits as a result of the acquisition of StorageTek by Sun, you will not be eligible for some or all of the benefits under the Plan for a period of time, as set forth in your offer letter from Sun dated on or around August 5-10, 2005.

Conditions For Receiving Plan Benefits

You
will receive Plan benefits if you are an Eligible Employee and meet all of the following conditions:



| |  |  | You inform Sun of your intent to retire and receive a formal written notice that states the date your employment will terminate and that your termination is because of Retirement or
Mutual Agreement (Termination Letter);
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | You abide by any written terms and requirements that Sun may establish as a condition to your receiving Plan benefits; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | For Severance Benefits only, you sign the Release and Waiver Agreement within a reasonable period of time (as determined by Sun in its sole discretion) after your employment
termination date and do not revoke the Release and Waiver Agreement within the seven (7) calendar day revocation period.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Retirement for purposes of this Plan means your voluntary resignation from Sun at or after attaining age 55 and with a number of full years of service with Sun that when added to your age (in full years), the sum equals
or exceeds 65. Notwithstanding the foregoing sentence, you must have a minimum of five (5) full years of service in order to qualify for Retirement. Your resignation will not be considered Retirement if you work in the same or similar
profession during the six-month period following your termination of employment. You will be considered to have retired if you perform services for a nonprofit organization following your termination of employment. Sun shall make the determination
of whether you have retired in its sole discretion.

Mutual Agreement for purposes of this Plan means that both you and Sun agree that
your employment should terminate.



---

Conditions Under Which You Will Not Receive Plan Benefits

Even if you are an Eligible Employee, you will not receive Plan benefits if any of the following apply:



| |  |  | You are involuntarily terminated with or without Cause. Cause means (i) misconduct as described in Suns Misconduct Policy (HR503) or (ii) documented
unsatisfactory job performance. Sun shall make this determination in its sole discretion.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | You voluntarily terminate employment (including as a result of disability) other than due to Retirement or Mutual Agreement even if you claim constructive termination,
prior to your termination date as set forth in your Termination Letter.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | You decline a written offer of a Comparable Job at Sun for which, in Suns judgment, you are reasonably qualified. A Comparable Job is a
job within 50 miles of your current job location at the same or higher salary/job grade as the current job and with at least the same total target cash compensation opportunity. A Comparable Job need not involve the same duties and responsibilities
as your current job.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | You accept another regular job at Sun before your employment at Sun terminates (i.e., a job other than a Temporary Job Assignment, defined below).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | You are on an unpaid personal non-FMLA, non-Military Leave of Absence on the date of the Termination Letter.
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | You begin working for another employer (whether regular or temporary) before your employment at Sun terminates. You are required to immediately notify Sun in writing if you begin
another job prior to your termination date.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Your job is re-leveled for any reason, for example, to reflect your current job duties and responsibilities or to reflect any changes in your job duties and responsibilities.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For Severance Benefits only, you do not timely sign a Release and Waiver Agreement or you timely sign a Release and Waiver Agreement but you revoke it within the seven calendar day
revocation period.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Temporary Job Assignments

For purposes of this Plan, a Temporary Job Assignment is a job as a Sun employee that is not expected to last more than two years at the time it is offered to you and which is offered to you after
you receive a Termination Letter but prior to your employment termination. If you accept a job which, at the time it is offered to you, is expected to last more than two years, you will be treated as a regular Sun employee and will not receive Plan
benefits in connection with the Retirement or Mutual Agreement that occurred immediately prior to your acceptance of your new job at Sun.



---

While you are on a Temporary Job Assignment you will not receive Plan benefits. However, at the end of the Temporary Job
Assignment, provided you meet the conditions of the Plan, you will receive Plan benefits in accordance with the terms of the Plan in effect as of the date of the Termination Letter.

If you accept a Temporary Job Assignment and it has not ended after two years, you will be treated as if you are in a regular position and will not be eligible for Plan benefits unless you terminate employment as a
result of Retirement or Mutual Agreement. In other words, you will not receive Plan benefits in connection with Retirement or Mutual Agreement that occurred immediately prior to your acceptance of your new job at Sun.

Notification Pay

You need not sign a Release and Waiver
Agreement in order to be eligible for Notification Pay.

If you are an Eligible Employee and you receive a written Termination Letter that your employment
will terminate, you will receive the following Notification Pay:



| |  |  | Notification Pay. You will remain employed for sixteen (16) weeks following the date of your Termination Letter. During this sixteen (16) week period, you will
receive your regularly bi-weekly Pay (defined below under Severance Benefits) and your Sun Flex benefits will continue, but you are not required to work during this time.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Note: If you are a Key Employee (defined below under Severance Benefits), your Notification Pay will be paid in one lump sum payment on the second Friday
(or as soon as administratively practical thereafter) that is six (6) months following the date of your Separation from Service (defined below under Severance Benefits).

Severance Benefits

When you receive a Termination Letter, you may choose to sign a Release and Waiver
Agreement in order to also receive Severance Benefits. You will have at least 45 calendar days after your employment termination date to sign the Agreement. If you do not sign and return to Sun a Release and Waiver Agreement within a
reasonable period of time (as determined by Sun in its sole discretion) after your employment termination date or you subsequently revoke the Agreement during the seven (7) calendar day revocation period, you will not be eligible to receive the
Severance Payment and the payment of COBRA Premiums described below. You may not sign the Release and Waiver Agreement prior to your employment termination date.

You will receive the following benefits on the second Friday after Sun receives your signed Release and Waiver Agreement and the revocation period has ended (or as soon as administratively practical thereafter):



| |  |  | Severance Payment. This is a lump sum payment equal to four (4) weeks Pay (defined below) for each Year of Service (defined below), up to a maximum
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



---

| | determined by your Position (defined below) plus sixteen (16) or thirty-two (32) weeks Pay determined by your Position.
| | -----------------------------------------------------------------------------------------------------------------------

Note: If you are a Key Employee (defined below), your Severance Payment will be paid on the second Friday (or as soon as
administratively practical thereafter) that is six (6) months following the date of your Separation from Service (defined below).



| |  |  | COBRA Premiums. Your existing coverage under Suns group health plan (and, if applicable, the existing group health coverage for your eligible dependents) will end on
the date on which your employment terminates. You and your eligible dependents may then be eligible to elect temporary continuation coverage under Suns group health plan in accordance with the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended (COBRA). If you are eligible for a Severance Payment and elect COBRA continuation coverage, Sun will pay your COBRA Premiums (defined below) for a period equal to the number of weeks of Pay you will receive as a
Severance Payment (not to exceed the maximum period of COBRA coverage). However, in no event may payment of COBRA Premiums continue beyond December 31 of the second calendar year following the calendar year in which you have a Separation from
Service. After such period of Sun-paid coverage, you (and, if applicable, your eligible dependents) may continue COBRA coverage at your own expense in accordance with COBRA. No provision of the Plan will affect the continuation coverage rules under
COBRA. Therefore, the period during which you must elect to continue Suns group health plan coverage under COBRA, the length of time during which COBRA coverage will be made available to you, and all your other rights and obligations under
COBRA will be applied in the same manner that such rules would apply in the absence of the Plan.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Key Employee means, in
general, one of Suns top fifty (50) officers based on compensation. The determination of which Eligible Employees are Key Employees will be made by Sun in its sole discretion in accordance with Sections 416(i) and 409A of the Internal
Revenue Code and the regulations promulgated thereunder. If you are determined to be a Key Employee on any December 31, then you will be considered a Key Employee for purposes of the Plan during the period beginning on the first April 1
following such December 31 and ending on the next March 31.

Separation from Service means, in general, the date you work less
than twenty percent (20%) of your average work schedule during the preceding three (3) full calendar years (or if you were employed by Sun for less than three (3) years, such lesser period). The determination of when your Separation
from Service occurs will be made by Sun in its sole discretion in accordance with Section 409A of the Internal Revenue Code and the regulations promulgated thereunder.

Year of Service for purposes of this Plan means a full or partial year of service with Sun prior to your employment termination date. If you are a rehired employee, prior service at Sun will be
counted as Year of Service provided that the prior service period



---

exceeded the period when you were not employed by Sun. Years of Service includes up to seven (7) (ten (10) for former employees of Procom
Technology, Inc.) years of service credit for service with a predecessor employer that was acquire by Sun; however, the service credit limit will not apply to former employees of Storage Technology Corporation and SeeBeyond Technology Corporation. A
partial year of service will be treated as a full year of service.

COBRA Premiums for purposes of this Plan are the COBRA premiums that
you would have to pay to continue for a certain period of time, the medical, dental, and/or vision coverage you had immediately prior to terminating employment.

Payfor purposes of this Plan (other than for sales-related incentive based positions) means your base pay as of the date of the Termination Letter, which does not include car allowance, draws, spifs, bonuses or any
non-base compensation. Pay for sales-related incentive based positions is based on the On-Target Earnings rate (OTE) effective on the date of the Termination Letter.

Positionfor purposes of this Plan means your position as either a member of the ELT or a Vice President who is not a member of the ELT on the date of the Termination Letter as recorded in
Suns HR Database.

Example of Calculation of Severance Payment

Assume you are a Vice President with eight years of service. The calculation of your Severance Payment is as follows:

16 weeks Pay based on the Pay you would have received had you worked for those 16 weeks, plus 20 weeks Pay*, for a total of 36 weeks of Pay.

*4 weeks Pay per Year of Service x 8 years = 32 weeks but the maximum allowed payment based on Years of Service is 20 weeks Pay. The 16 weeks of Pay
is not included in calculating the maximum payment based on Years of Service.

Stock Options

If your employment terminates because of Retirement and you are eligible to receive benefits under the Plan, your stock options that would have vested during the 15
months following your employment termination date will become immediately vested on your employment termination date. Except as provided in the previous sentence, all other terms and conditions of your option agreements remain the same.

Sales-Related Incentive Based Positions

If you are in a
sales-related incentive based position, commission earnings end effective the date of your Termination Letter. Base pay will be used to determine the payment of unused, accrued vacation in your final paycheck.



---

Obligation to Repay Sun

If you are reemployed by Sun (in any capacity) before the end of the number of weeks used to determine your Severance Benefits, you must repay to Sun the portion of your Severance Payment for the period that you have
been reemployed.

For example, if you are a Vice President with eight years of service, you would have received 36 weeks of Pay. If you were then
reemployed by Sun 4 weeks following your employment termination date, you would be required to repay to Sun an amount calculated as follows:

36 weeks of Severance Payment paid minus 4 weeks of actual unemployment equals 32 weeks of Severance Payment to be repaid to Sun.

Reduction
of Other Benefits

Any Notification Pay received under this Plan will reduce the amount of any short term and long term disability benefits you are
entitled to receive under the Sun Microsystems, Inc. Comprehensive Welfare Plan.

Taxes and Other Deductions

Sun will withhold all appropriate federal, state, local, income and employment taxes from your Plan benefit payments. Contributions to Suns 401(k) plan and employee
stock purchase plan will not be deducted from your Severance Payment or any Notification Pay paid after your employment termination date.

Bonus
Programs

The Plan does not change the terms of any bonus program for which you may have been eligible at the time of your termination with Sun.

Accordingly, if you are eligible for a bonus payment under a program operated on a quarterly or fiscal year basis (such as SMI Bonus) and terminate
employment prior to the last day of a quarter or fiscal year, you will not be eligible to receive the bonus for the quarter or fiscal year in which you terminate employment, except to the extent the bonus program provides otherwise. Unless the bonus
program provides otherwise, bonus program payments will not be prorated for a partial quarters or years participation.

Disability Prior
to Employment Termination

If you become disabled after receiving a Termination Letter but before you terminate employment, your employment
termination date will not change. You should contact SunDial to discuss the employment disability benefits for which you may be eligible.



---

Death Prior to Employment Termination

If you die after receiving a Termination Letter but before you sign the Release and Waiver Agreement, neither you nor your estate will be entitled to any further Plan benefits.

Plan Operation, Administration and General Provisions

Other Benefit Plans/Agreements

Your rights and participation in any
other Sun benefit plan at termination of employment are governed solely by the terms of those other plans. Amounts you receive under the Plan will be reduced by any other type of severance (or similar) payment you receive under any plan or agreement
(including any change of control agreement), if any (including any payments pursuant to a Sun foreign subsidiarys or an acquired companys plan or agreement) or as required by law.

Amendment and Termination

Sun reserves the right to modify, suspend
or terminate the Plan at any time and for any reason. Any action amending or terminating the Plan shall be in writing and shall be approved by the Leadership and Development Compensation Committee of the Board of Directors of Sun.

Unfunded Plan

All Plan benefits are paid from Suns general
funds, and each participant is an unsecured general creditor of Sun. Nothing contained in the Plan creates a trust fund of any kind for your benefit or creates any fiduciary relationship between you and Sun with respect to any of Suns assets.
Sun is under no obligation to fund the benefits provided under the Plan prior to payment.

Plan Benefits Cannot Be Assigned

The rights of any person to any benefit under the Plan may not be made subject to option or assignment, either by voluntary or involuntary assignment or by operation of
law, including bankruptcy, garnishment, attachment or other creditors process. Any act in violation of this rule shall be void.

No Employment
Rights

Nothing in the Plan may be deemed to give any individual a right to remain employed by Sun or affect Suns right to terminate an
individuals employment at any time, with or without cause.

Legal Construction

The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA), and, to the extent not preempted by ERISA, California law. If any provision of the Plan is
held by a court of competent jurisdiction to be invalid or unenforceable, the remaining provisions of the Plan shall continue to be fully effective.

Plan Administrator

Sun is the Plan Administrator of the Plan as that term is used in ERISA. Sun has full discretionary
authority to administer and interpret the Plan, including the exclusive right



---

to adopt rules and procedures to implement the Plan, to interpret in its sole discretion, provisions of the Plan, to decide any questions in connection with
the administration of the Plan, or relating to any claim for Plan benefits, including, whether an individual is eligible for Plan benefits and the amount of Plan benefits. Sun may delegate its responsibilities to other persons, which includes
delegation of discretion. Subject to the claims and appeal procedures, the decisions of Sun and its delegatees relating to the Plan are final and binding on all persons.

Claims and Appeal Procedures

If you disagree with Suns determination of the amount of your benefits or
with any other decision Sun may have made regarding your interest in the Plan, you may file a claim with Sun. You must send your claim in writing to: Director, Executive Compensation  U.S. Vice President Severance Plan, Sun Microsystems, Inc.,
4230 Network Circle, M/S USCA23-106, Santa Clara, CA 95054. You should file the claim as soon as possible, but no later than one (1) year after the determination /decision.

In the event that your claim for benefits is denied in whole or in part, Sun must provide you written or electronic notification of the denial of the claim, and of your right to appeal the denial. The notice of denial
will be set forth in a manner designed to be understood by you, and will include (i) the specific reason or reasons for the denial, (ii) reference to the specific Plan provisions upon which the denial is based, (iii) a description of
any information or material that Sun needs to complete the review and an explanation of why such information or material is necessary, and (iv) an explanation of the Plans appeal procedures and the time limits applicable to such
procedures, including a statement of your right to bring a civil action under Section 502(a) of ERISA following a denial on appeal. This notice will be given to you within 90 calendar days after Sun receives the claim, unless special
circumstances require an extension of time  in which case Sun has up to an additional 90 calendar days for processing the claim. If an extension of time for processing is required, notice of the extension will be furnished to you before the
end of the initial 90-day period. This notice of extension will describe the special circumstances necessitating the additional time and the date by which Sun expects to render its decision on the claim.

If your claim for benefits is denied, in whole or in part, you (or your authorized representative) may appeal the denial by submitting a written appeal to the Appeal
Committee within 60 calendar days after you receive the denial. If you fail to appeal a denial within the 60-day period, Suns determination will be final and binding. If you appeal to the Appeal Committee, you (or your authorized
representative) may submit comments, documents, records and other information relating to your claim for benefits. You may request (free of charge) reasonable access to, and copies of, all documents, records, and other information relevant to your
claim.

The Appeal Committee will make a decision on each appeal no later than 60 calendar days following receipt of the appeal. If special circumstances
require an extension of time for processing the appeal, the Appeal Committee will make a decision on the appeal no later than 120 calendar days following receipt of the appeal. If an extension for



---

review is required, notice of the extension will be furnished to you before the extension begins. The extension notice will indicate the special
circumstances requiring an extension and the date by which the Appeal Committee expects to render a decision. The Appeal Committee will give written or electronic notice of its decision to you after its decision is made. In the event that the Appeal
Committee confirms the denial of the claim for benefits in whole or in part, the notice will outline, in a manner calculated to be understood by you, (i) the specific reason or reasons for the decision, (ii) reference to the specific Plan
provisions upon which the decision is based, (iii) a statement that you may request (free of charge) reasonable access to, and copies of, all documents, records, and all other information relevant to your claim, and (iv) a statement of
your right to bring an action under Section 502(a) of ERISA.

No legal action for benefits under the Plan may be brought until you (i) have
submitted a written claim for benefits in accordance with the procedures described above, have been notified by Sun that the claim is denied, have filed a written appeal in accordance with the appeal procedures described above, and have been
notified that the Appeal Committee has denied the appeal, or (ii) Sun or the Appeal Committee fail to follow these procedures. No legal action may be commenced or maintained against the Plan, Sun or the Appeal Committee more than two
(2) years after the Appeal Committee denies your appeal or Sun or the Appeal Committee fail to follow these procedures.

If you wish to take legal
action after exhausting the appeal procedures, you may serve process on Sun at the address indicated in the section below entitled Plan Information.

Statement of ERISA Rights and Protections

As a participant in the Sun Microsystems, Inc. U.S. Vice President Severance Plan, you are entitled to certain rights and protections under ERISA. ERISA provides that all plan participants are entitled to:

Receive Information About your Plan and Benefits

Examine, without
charge, at the plan administrators office - and at other specified locations - all documents governing the Plan and a copy of the latest annual report (Form 5500 Series) filed by the Plan with the U.S. Department of Labor and available at the
Public Disclosure Room of the Employee Benefits Security Administration.

Obtain, upon written request to the plan administrator, copies of documents
governing the operation of the plan, copies of the latest annual report (Form 5500 Series) and updated summary plan description (there may be a reasonable charge for the copies).

Prudent Actions by Plan Fiduciaries

In addition to creating rights for plan participants, ERISA imposes obligations
on those responsible for the operation of the Plan. The people who operate the Plan, called fiduciaries of the Plan, have a duty to do so prudently and in the interest of you and other plan participants and beneficiaries. No one,
including Sun or any other individual, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a benefit or exercising your rights under ERISA.

Enforce Your Rights

If your claim for a benefit is denied or ignored, in whole or in part, you have a right to know
why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules.

Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of plan documents or the latest annual report from the plan administrator and do not receive them within 30 days, you may file suit
in a Federal court. In such a case, the court may require the plan administrator to provide the materials and pay you up to $110 a day until you receive them, unless the materials were not sent because of reasons beyond the administrators
control. If your claim for benefits is denied or ignored, in whole or in part, and you have been through the Plans appeal procedures, you may sue in a state or Federal court. If it should happen that plan fiduciaries misuse the Plans
money, or if you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit



---

in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you sued to pay
these legal costs and fees. If you lose, the court may order you to pay these costs and fees (for example, if it finds your claim is frivolous).

Assistance With Your Questions
