Form of Amendment to Performance Based Stock Unit Agreement – 2002 Plan

AMENDMENT TO DELL INC.

PERFORMANCE BASED STOCK UNIT AGREEMENT

THIS AMENDMENT, effective as of April 17, 2013, is to each Performance Based Stock Unit Agreement by and between Dell Inc., a Delaware corporation (the “Company”), and you in effect as of April 17, 2013 (each, the “Performance Based Stock Unit Agreement”), in connection with the Units representing the right to receive that number of shares of the Company’s common stock (the “Shares”) calculated as set forth in the Performance Based Stock Unit Agreement and your applicable Grant Summary, subject to the terms and conditions of the Performance Based Stock Unit Agreement. All terms used herein with their initial letters capitalized shall have the meanings given them in the Performance Based Stock Unit Agreement or the Dell Inc. Amended and Restated 2002 Long-Term Incentive Plan (the “Plan”) unless otherwise defined herein. For purposes of this Amendment, the Grant Summary shall be treated as a constituent part of the Performance Based Stock Unit Agreement.

On April 17, 2013, the Leadership Development and Compensation Committee (the “Committee”) of the Board of Directors of the Company (the “Board”) determined to amend certain outstanding equity awards to provide certain benefits to holders of such awards in the event of a Change in Control (as defined below). Accordingly, the Performance Based Stock Unit Agreement is hereby amended as follows:

12. Change in Control — Notwithstanding the method of determining the number of Units awarded and the vesting schedule set forth in the Grant Summary to the Performance Based Stock Unit Agreement, in the event of a Change in Control (as defined below), the performance goals described in the Performance Based Stock Unit Agreement shall be deemed attained (a) at such level as is agreed to by the Board and set forth in any agreement pursuant to which the transactions constituting the Change in Control are effected (the “Transaction Agreement”) or (b) in the event that no deemed attainment of performance goals is specified in the Transaction Agreement or the Change in Control occurs without the execution of a Transaction Agreement to which the Company is a party, at the Target set forth in the Grant Summary (the number of Shares so determined referred to hereafter as the “Shares Deemed Deliverable”). Except as provided below in this Section 1, your Units with respect to the Shares Deemed Deliverable shall continue to vest in accordance with the service-based vesting schedule in your Grant Summary, and shall be settled in Shares if, when and to the extent you become vested in the Units. If there is no service-based vesting schedule set forth in the Grant Summary, for purposes of this Section 1, the vesting date shall be the last day of the Performance Period. Notwithstanding the foregoing, in the event of a Change in Control, either of the Committee or the Board shall have the right, in its discretion, prior to or at the effective time of the consummation of such Change in Control, to direct that in lieu of being eligible to receive Shares upon settlement of your rights under the Performance Based Stock Unit Agreement you instead will be eligible to receive either (x) a payment in cash equal to the value of the Shares Deemed Deliverable (without interest or earnings), based on the amount payable to the Company’s stockholders in connection with the Change in Control under the Transaction Agreement or, in the case of a Change in Control effected without a Transaction Agreement to which the Company is a party, the fair market value of a Share at the date the Change in Control occurs (the “Substitute Cash Consideration”), or (y) shares of the capital stock of any Person successor to the Company or affiliate of such successor Person, or other consideration (the “Substitute Property Consideration” and together with the Substitute Cash Consideration, the “Substitute Consideration”), so long as such Substitute Property Consideration is, in the good faith judgment of the Committee or the Board, as applicable, of value equal to or greater than the value of such Shares Deemed Deliverable. If your Shares Deemed Deliverable are replaced by Substitute Consideration, you will be entitled to payment of such Substitute Consideration if, when and to the extent you satisfy the service-based vesting conditions that applied to the Shares Deemed Deliverable to which such Substitute Consideration is attributable (or any more favorable vesting conditions applicable to the Units as may be set forth in the applicable Transaction Agreement). If there is no service-based vesting schedule set forth in the Grant Summary, for purposes of this Section 1, the vesting date shall be the last day of the Performance Period (or such more favorable vesting date or dates as may be set forth in the applicable Transaction Agreement). Notwithstanding the foregoing, if your employment is terminated by the Company or the Company affiliate with which you are employed without Cause (as defined below) on or following the effective time of the Change in Control and prior to the 24 month anniversary of the effective time of the Change in Control, you will become 100% vested as of your date of employment termination as to all of your Shares Deemed Deliverable (or if the Committee or the Board shall have determined that your rights under the Performance Based Stock Unit Agreement shall be settled in Substitute Cash Consideration or Substitute Property Consideration, such Substitute Consideration) and payment or delivery thereof shall be made within ten days following your date of employment termination.
