Exhibit 10.3

SUN MICROSYSTEMS LTD

Severance Agreement With

Peter Ryan

This Agreement is hereby entered into by
Sun Microsystems LTD, and its successor or successors (collectively referred to as Sun) with Peter Ryan (Executive).

The Sun
Microsystems LTD Severance Agreement With Peter Ryan (the Agreement) provides Notification Pay and Severance Benefits if Executives employment terminates because of a Retirement, Mutual Agreement, Material Job Change, Workforce
Reduction, or Involuntary Termination. However, this Agreement does not provide benefits (i) if Executive voluntarily terminates employment (other than Mutual Agreement or Material Job Change) prior to qualifying for Retirement, (ii) if
Executive is involuntarily terminated for Cause or (iii) if Executive is entitled to or has received payments under a change of control agreement. Executive must sign, and not revoke, a Release and Waiver Agreement which releases all Sun
entities (Release & Waiver), in order to receive Severance Benefits.

The Agreement is intended to comply with Code § 409A of the
Internal Revenue Code. The Agreement is also intended to satisfy, where applicable, any obligations of Sun under the Federal Worker Adjustment and Retraining Notification (WARN) Act.

Notification Pay and Severance Benefits

Under
this Agreement, Executive is eligible to receive two types of Benefits: Notification Pay and Severance Benefits if Executives employment terminates because of a Retirement, Mutual Agreement, Material Job Change, Workforce Reduction, or
Involuntary Termination and Executive meets the conditions for receiving the benefits under this Agreement.

You are entitled solely to the
Notification Pay and Severance Benefits defined below and only if you meet the conditions for receiving the benefits under this agreement. This Severance Agreement amends and replaces in its entirety the Section entitled
NOTICE in the Sun Microsystems LTD Written Statement of Terms and Conditions of Employment that you signed on 23 May 2006 and amends and replaces any other agreement as well as any other termination practice and/or entitlement
existing within Sun Microsystems LTD at the time of Separation from Service (as determined by Sun Microsystems, Inc. in accordance with Code § 409A).

Notification Pay consists of Employment Transition Services and a lump sum payment equal to 16 weeks of Weekly Base Pay. Executive does not need to sign a Release & Waiver in order to receive
Notification Pay. If Executive receives a written Termination Letter that Executives employment will terminate, Executive will receive Notification Pay. Sun will pay the lump sum amount as soon as administratively practicable following receipt
by the Executive of the written Termination Letter and Executives Separation from Service (as determined by Sun Microsystems, Inc. in accordance with Code § 409A), unless Executive is a Key Employee (as determined by Sun
Microsystems, Inc. in accordance with Code § 409A). If Executive is a Key Employee, Sun will pay Executives Notification Pay in one lump sum payment on the date (or as soon as administratively practical thereafter) that is six
(6) months following the date of Executives Separation from Service (as determined by Sun in accordance with Code § 409A).

Severance Benefits consist of a lump sum cash payment and payment on behalf of the
Executive of Continuation of Coverage Premiums, based on eligibility and selection of coverage by the Executive, for the number of weeks for which the lump sum cash payment is paid by Sun. The lump sum cash payment (Severance Payment)
shall be equal to 1 times Executives Weekly Base Pay times the sum of 32 weeks plus 4 weeks for each Year of Service; however, the sum shall not exceed a total of 64 weeks. Executive will not receive Severance Benefits if Executive does not
sign a Release & Waiver, or if Executive signs the Release & Waiver but revokes it within the seven (7) calendar day revocation period.

After Executive receives a Termination Letter, and is terminated per the terms of that letter, Executive may choose to sign the Release & Waiver in order to also receive Severance Benefits. Executive will have 45 calendar days
after Executives employment termination date to sign the Release & Waiver. If Executive does not sign and return the Release &Waiver to Sun within the 45 days after Executives employment termination date or Executive
subsequently revokes the Release & Waiver during the seven (7) calendar day revocation period, Executive will not be eligible to receive the Severance Payment and the payment arrangement of Continuation of Coverage Premiums. Executive
may not sign the Release & Waiver prior to Executives employment termination date.

In the event the Release & Waiver is signed and
not revoked in accordance with the previous paragraph, Sun will pay the Severance Payment 45 days following Executives Separation from Service (as determined by Sun Microsystems, Inc. in accordance with Code § 409A) (or as soon as
administratively practicable thereafter), unless Executive is a Key Employee (as determined by Sun Microsystems, Inc. in accordance with Code § 409A). If Executive is a Key Employee, Sun will pay Executives Severance Payment in one single
sum payment on the date (or as soon as administratively practicable thereafter) that is six (6) months following the date of Executives Separation from Service (as determined by Sun Microsystems, Inc. in accordance with Code
§ 409A).

Employment Transition Services for purposes of this Agreement means career service assistance for
eighteen (18) months. Employment Transition Services become available to Executive on the date of Executives Separation from Service (as determined by Sun in accordance with Code § 409A) and continue for eighteen
(18) months thereafter. In no event may Employment Transition Services continue beyond December 31 of the second calendar year following the calendar year in which the Executives Separation from Service (as determined by Sun
Microsystems, Inc. in accordance with Code § 409A) occurs.

Continuation of Coverage:If Executive is eligible for a
Severance Payment and elects Continuation of Coverage under COBRA or the then current available local policy (if offered), Sun will pay Executives premiums to Suns plan administrator or benefit provider, where applicable, for a period
equal to the number of weeks of Weekly Base Pay Executive will receive as a Severance Payment (not to exceed the maximum period of plan eligible coverage). However, in no event may payment premiums (under COBRA or otherwise) continue beyond
December 31 of the second calendar year following the calendar year in which Executive has a Separation from Service. If Executive is eligible for COBRA, then the section below regarding COBRA will apply.

COBRA Premiums for purposes of this Agreement are the COBRA premiums that Executive would have to pay to continue for a certain period
of time, the medical, dental, and/or vision coverage that Executive had immediately prior to terminating employment. Executives existing coverage under Suns group health plan (and, if applicable, the existing group health coverage for
Executives enrolled eligible dependents) will end on the date on which Executives employment terminates. Executive and his 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). Upon the conclusion of any Sun-paid coverage, Executive (and, if applicable, Executives eligible dependents) may continue COBRA
coverage at Executives own expense in accordance with COBRA. No provision of the Agreement will affect the continuation coverage rules under COBRA. Therefore, the period during which Executive 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 Executive, and all other rights and obligations under COBRA will be applied in the same manner that such rules would apply in the absence of the
Agreement.

on a quarterly or fiscal year basis (such as SMI Bonus) and terminates employment prior to the last day of a quarter or fiscal year, Executive will not be eligible to receive the bonus for the quarter or fiscal year in which Executive terminates

Administration and General Provisions

Executives rights and participation in any other Sun benefit plan at termination of employment are governed solely by the terms of those other plans.

Unfunded Agreement

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

Benefits Cannot Be Assigned

The rights of any person to any benefit under the Agreement 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 Agreement 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 Agreement 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 Agreement is held by a court of competent jurisdiction to be invalid or unenforceable, the remaining provisions of the Agreement shall continue to be fully effective.

Interpretation and Delegation

Sun has full discretionary
authority to administer and interpret the Agreement, including the exclusive right to adopt rules and procedures to implement the Agreement, to interpret in its sole discretion, provisions of the Agreement, to decide any questions in connection with
the administration of the Agreement, or relating to any claim for Benefits, including, whether an individual is eligible for Benefits and the amount of 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 Agreement are final and binding on all persons.
