Optionee: [NAME]

STOCK OPTION AGREEMENT

PURSUANT TO THE

SUNEDISON SEMICONDUCTOR LIMITED

2014 LONG-TERM INCENTIVE PLAN

The Board of Directors (together with any designee thereof, the “Board”) of SunEdison Semiconductor Limited (the “Company”), has determined that [NAME] (the “Optionee”) is eligible and deserving of an award under the SunEdison Semiconductor Limited 2014 Long-Term Incentive Plan, as amended from time to time (the “Plan”), a copy of which is attached hereto as Exhibit B. This Agreement is subject to the terms of the Plan in all respects, and specific reference shall be made to the Plan in determining the Optionee’s rights and obligations hereunder. If any provisions of this Agreement and the Plan conflict, the provisions of the Plan shall control. Capitalized terms which are used herein and not otherwise defined shall have the meanings set forth in the Plan. This Agreement is an “Agreement” as such term is defined in the Plan.

This Agreement is made by and between the Company and the Optionee as follows:

1. Grant of Option. The Optionee is hereby granted, as of the Grant Date set forth on Exhibit A attached hereto (the “Grant Date”), an Option (the “Option”) to purchase the number of shares of Common Stock set forth on Exhibit A attached hereto (the “Option Shares”). This Option shall constitute a Non-Qualified Stock Option. Except as otherwise provided by the Plan, the Optionee agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Optionee with any protection against potential future dilution of the Optionee’s interest in the Company for any reason. The Optionee shall have no rights as a stockholder with respect to any shares of Common Stock covered by the Option unless and until the Optionee has become the holder of record of such shares, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such shares, except as otherwise specifically provided for in the Plan or this Agreement.

2. Purchase Price. The exercise price applicable to this Option will be the amount per share set forth on Exhibit A attached hereto (the “Purchase Price”), which amount is at least equal to the Fair Market Price of a share of Common Stock as of the Grant Date. The number of Option Shares and Purchase Price per Option Share under this Option are subject to adjustment as provided in the Plan.

3. Term. This Option shall have the term, subject to earlier termination as provided herein or in the Plan, set forth on Exhibit A attached hereto.

4. Exercise of Option. Subject to the provisions of this Agreement and the Plan, and subject to Optionee’s Continuous Service, this Option shall vest according to the schedule set forth on Exhibit A attached hereto, and any vested portion of the Option shall be exercisable, in whole or in part, at any time or from time to time prior to the expiration of the Option or as

1

provided herein by the filing of any written form of exercise notice as may be required by the Committee and payment in full of the Purchase Price set forth on Exhibit A multiplied by the number of shares of Common Stock underlying the portion of the Option exercised. At the discretion of the Optionee, the Optionee may elect to acquire Option Shares upon exercise without payment in cash for the Purchase Price. Such a cashless exercise shall be effectuated by the Company delivering shares of Common Stock to the Participant with a Fair Market Value equal to the difference between (i) the aggregate Fair Market Value of the Option Shares to be acquired upon such exercise, minus (ii) the aggregate exercise price payable by the Optionee for the then vested Options underlying such Option Shares. To the extent exercisable, this Option may be exercised in whole or in part and from time to time until fully exercised or until the Option expiration date set forth on Exhibit A attached hereto or until this Option terminates under the Plan and this Agreement. In no event, however, shall this Option be exercisable in whole or in part after the expiration of ten years from the Grant Date. This Option may be exercised only in accordance with the terms and conditions of the Plan.

(a) Termination of Continuous Service. In the event the Optionee’s Continuous Service terminates (other than upon the Optionee’s death or Disability), the unvested portion of the Option shall be immediately forfeited for no additional consideration, and Optionee may exercise the vested Option (to the extent that the Optionee was entitled to exercise this Option as of the date of termination) but only within such period of time ending on the earlier of: (i) the date three months following the termination of the Optionee’s Continuous Service; or (ii) the expiration of the Term of this Option; provided that, if the termination of Continuous Service is by the Company for Cause, all outstanding Options (whether or not vested) shall immediately terminate and cease to be exercisable. If, after termination, the Optionee does not exercise any vested portion of this Option within the period described in the preceding sentence, such vested portion of the Option shall terminate for no additional consideration.

(b) Disability of Optionee. In the event that the Optionee’s Continuous Service terminates as a result of the Optionee’s Disability, the unvested portion of the Option shall be immediately forfeited for no additional consideration, and Optionee may exercise the vested portion Option (to the extent that the Optionee was entitled to exercise this Option as of the date of termination), but only within such period of time ending on the earlier of: (1) the date 12 months following such termination; or (2) the expiration of the Term of this Option. If, after termination, the Optionee does not exercise any vested portion this Option within the period described in the preceding sentence, such vested portion of the Option shall terminate for no additional consideration.

(c) Death of Optionee. In the event the Optionee’s Continuous Service terminates as a result of the Optionee’s death, the unvested portion of the Option shall be immediately forfeited for no additional consideration, and the vested portion of the Option may be exercised (to the extent the Optionee was entitled to exercise this Option as of the date of death) by the Optionee’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionee’s death, but only within the period ending on the earlier of: (1) the date 12 months following the date of death; or (2) the expiration of the Term of this Option. If, after termination, the Optionee’s estate does not exercise the vested portion of the Option within the period described in the preceding sentence, such vested portion of the Option shall terminate for no additional consideration.

2

(d) Change in Control. Notwithstanding anything contained herein to the contrary, in the event of the Optionee’s termination of Continuous Service without Cause or for Good Reason during the 12-month period following a Change in Control Date, this Option shall become immediately exercisable with respect to 100% of the Option Shares. In addition, in the event of a Change in Control, an Award may be treated, to the extent determined by the Committee to be permitted under Section 409A of the Code, in accordance with such method provided for under the Plan as determined by the Committee in its sole discretion.

5. Certain Taxes. The Company shall have the power and the right to deduct or withhold, or require the Optionee to remit to the Company, an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Optionee’s FICA and SDI obligations) which the Company, in its sole discretion, deems necessary to be withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the Option and, if the Optionee fails to do so, the Company may otherwise refuse to issue or transfer any shares of Common Stock otherwise required to be issued pursuant to this Agreement. Any minimum statutorily required withholding obligation with regard to the Optionee may be satisfied by reducing the amount of cash or shares of Common Stock otherwise deliverable upon exercise of the Option.

6. Transfer Restrictions. The Option, and any rights and interests with respect thereto, issued under this Agreement and the Plan shall not be sold, exchanged, transferred, assigned or otherwise disposed of in any way by the Optionee (or any beneficiary of the Optionee), other than by testamentary disposition by the Optionee or the laws of descent and distribution. Notwithstanding the foregoing, the Committee may, in its sole discretion, permit the Option to be transferred to a family member for no value, provided that such transfer shall only be valid upon execution of a written instrument in form and substance acceptable to the Committee in its sole discretion evidencing such transfer and the transferee’s acceptance thereof signed by the Optionee and the transferee, and provided, further, that the Option may not be subsequently transferred other than by will or by the laws of descent and distribution or to another family member (as permitted by the Committee in its sole discretion) in accordance with the terms of the Plan and this Agreement, and shall remain subject to the terms of the Plan and this Agreement. Any attempt to sell, exchange, transfer, assign, pledge, encumber or otherwise dispose of or hypothecate in any way the Option, or the levy of any execution, attachment or similar legal process upon the Option, contrary to the terms and provisions of this Agreement and/or the Plan shall be null and void and without legal force or effect.
