ON SEMICONDUCTOR

2000 STOCK INCENTIVE PLAN

ON Semiconductor Corporation, a Delaware Corporation (“Company”), hereby grants to ________________ (“Grantee”), a Participant in the ON Semiconductor Corporation (formerly known as SCG Holding Corporation) 2000 Stock Incentive Plan (“Plan”), as amended, a Performance Based Restricted Stock Units Award (“Award”) for Units (“Units”) representing shares of the Company’s Common Stock (“Stock”). The grant is made effective as of the __________ __, ____(“Grant Date”). This Award is designated as a “Performance Based Restricted Stock Unit Award,” and as such is granted under the Performance Share Award portion of the Plan.

A. The Board of Directors of the Company (“Board”) has adopted the Plan as an incentive to retain members of the Board, and key employees, officers and consultants of the Company and to enhance the ability of the Company to attract new members of the Board, employees, officers and consultants whose services are considered unusually valuable by providing an opportunity for them to have a proprietary interest in the success of the Company.

B. Under the Plan, the Board has delegated its authority to administer the Plan to the Compensation Committee of the Board (“Compensation Committee”)

C. The Compensation Committee approved the granting of Units to the Grantee pursuant to the Plan to provide an incentive to the Grantee to focus on the long-term growth of the Company.

D. To the extent not specifically defined in this Performance Based Restricted Stock Units Award Agreement (“Agreement”), all capitalized terms used in this Agreement shall have the meaning set forth in the Plan.

In consideration of the mutual covenants and conditions hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Grantee agree as follows:

1. Grant of Units. Grantee is hereby granted a Performance Based Restricted Stock Units Award for _____________________ Units, representing the right to receive the same number of shares of the Company’s Stock, subject to the terms and conditions in this Agreement.

2. Vesting of Units and Related Information.

2.1 Vesting Schedule. Subject to the terms and conditions set forth in this provision 2 and in other provisions of this Agreement, the Units will vest (if at all) on each Vesting Date (as defined below) beginning in the ________ quarter of ____ and ending on the Vesting Date for the __________ quarter of ____ provided some or all of the below performance measures (“Performance Measures”) are achieved. For purposes of this Agreement, the term “Vesting Date” means the date the Company files its Form 10-Q or 10-K during each fiscal quarter, subject to the achievement of relevant Performance Measures.

2.2 Terms and Conditions of Vesting.

(a) If the Minimum Performance Measure is met for the quarter, 50% of the eligible Units shall vest on the relevant Vesting Date. If the applicable Target Performance Measure is met for the quarter, the other 50% of the eligible Units shall vest on the relevant Vesting Date.

(b) If the Minimum Performance Measure is not met for the quarter, no portion of the Units shall vest on the relevant Vesting Date. Any unvested Units will carry forward to subsequent quarters until the Minimum Performance Measure or Target Performance Measure is met, and then all Units carried forward related to these measures shall vest on the relevant Vesting Date.

(c) If the Minimum Performance Measure is met on the relevant Vesting Date, but the Target Performance is not met, 50% of the eligible Units shall vest on the relevant Vesting Date. The remaining 50% of Units shall carry forward to subsequent quarters until the Target Performance Measure is met, and then all Units carried forward related to this measure shall vest on the relevant Vesting Date.

2.3 Non-GAAP EBITDA. For the purposes of the above vesting schedule the “Non-GAAP EBITDA” shall mean the Company’s earnings before interest (income or expense), taxes, depreciation, and amortization (or “EBITDA”) for the applicable quarter, calculated pursuant to the adjustments in 2.4; provided, however, if the Compensation Committee determines that an alternative method would be more appropriate to achieve the objectives of this Award then such method shall be applied to determine Non-GAAP EBITDA for purposes of the above 2.1 vesting schedule for any given quarter. “GAAP” refers to U.S. generally accepted accounting principles consistently applied.

2.4 Adjustments to Non-GAAP EBITDA. The Non-GAAP EBITDA of the Company shall be adjusted to exclude the following, without duplication and if applicable to the Company for Non-GAAP EBITDA for a relevant quarter: (i) amortization of purchased intangible assets; (ii) in-process research and development expense; (iii) stock-based compensation expense from acquisitions; (iv) stock-based compensation expense determined in accordance with Statement of Financial Accounting Standards No. 123 (as revised and amended); (v) restructuring, asset impairments and other, net; (vi) gain (loss) on debt prepayment; (vii) goodwill impairment charge; (viii) cumulative effect of accounting change required by GAAP; (ix) extraordinary item; (x) expensing of the step up to fair market value of inventory from acquisitions; and (xi) divestiture related items. Non-GAAP EBITBA, as adjusted, shall specifically include merger and acquisition activity of the Company.

In addition, the Compensation Committee may adjust either the Minimum Performance Measure or Target Performance Measure, as it deems appropriate in its sole discretion, to exclude the effect (whether positive or negative) of any of the following types of events or matters with respect to the Company occurring after the Grant Date of the Award: other unusual or infrequent matters or events, or special items similar to the items that the Company excludes or includes (as applicable) when calculating its Non-GAAP EBITDA. Each such adjustment, if any, shall be made solely for the purpose of providing a consistent basis from period to period for the calculation of the Minimum Performance Measure and Target Performance Measure in order to prevent the dilution or enlargement of the Grantee’s rights with respect to the Award.

2.5 Final Determination of Performance Measures Attained. The Company (or the Compensation Committee with respect to grants to covered employees under Section 162(m) of the U.S. Internal Revenue Code (“Code”)) shall be responsible for determining in good faith whether, and to what extent, the Performance Measures set forth in this Agreement have been achieved. The Company or the Compensation Committee, as applicable, may reasonably rely on information from, and representations by, individuals within the Company in making such determination and when made such determination shall be final and binding on the Grantee.

3. Termination of Employment.

3.1 General. Subject to the provisions of 3.2 below, if the Grantee terminates employment with the Company for any reason (including upon a termination for Cause), any Units that are not vested under the schedule in 2.1 above will be canceled and forfeited as of the date of termination of employment or service. In no event shall any Units vest after the Vesting Date for the first quarter of 2012.

3.2 Change in Control. If the Company terminates the Grantee’s employment without Cause (including a deemed termination for Good Reason, if applicable for this Grantee, as defined in Grantee’s employment agreement or similar document) within two (2) years following a Change in Control, then the unvested portion of the Units shall become immediately vested.

4. Time and Form of Payment. Subject to the provisions of the Agreement and the Plan, as the number of Units vest under 2 above, the Company will deliver to the Grantee the same number of whole shares of Stock, rounded up or down. Notwithstanding the preceding, the Company must deliver these shares (if any) within 15 days of the date of vesting.

5. Nontransferability. The Units granted by this Agreement shall not be transferable by the Grantee or any other person claiming through the Grantee, either voluntarily or involuntarily, except by will or the laws of descent and distribution or as otherwise provided under Section 13.5 of the Plan.

6. Adjustments. In the event of a stock dividend or in the event the Stock shall be changed into or exchanged for a different number or class of shares of stock of the Company or of another corporation, whether through reorganization, recapitalization, stock split-up, combination of shares, merger or consolidation, there shall be substituted for each such remaining share of Stock then subject to this Agreement the number and class of shares of stock into which each outstanding share of Stock shall be so exchanged, all as set forth in Section 14 of the Plan.

13. Tax Withholding. Pursuant to Section 17.3 of the Plan, unless otherwise provided by the Compensation Committee prior to the vesting of shares/Units as set forth in the next sentence, the Grantee shall satisfy any federal, state, local or foreign employment or income taxes due upon the vesting of the Units (or otherwise) by having the Company withhold from those shares of Stock that the Grantee would otherwise be entitled to receive, a number of shares having a Fair Market Value equal to the minimum statutory amount necessary to satisfy the Company’s applicable federal, state, local and foreign income and employment tax withholding obligation. In lieu of, and subject to, the above, the Compensation Committee may also permit the Grantee to satisfy any federal, state, local, or foreign employment or income taxes due upon the vesting of shares of the Units (or otherwise) by: (i) personal check or other cash equivalent acceptable to the Company; (ii) permitting the Grantee to execute a same day sale of Stock pursuant to procedures approved by the Company; or (iii) such other method as approved by the Compensation Committee, all in accordance with applicable Company policies and procedures and applicable law.

14. Amendments. This Agreement may be amended only by a written agreement executed by the Company and the Grantee.

15. Integrated Agreement. Any grant notice, this Agreement and the Plan shall constitute the entire understanding and agreement of the Grantee and the Company with respect to the subject matter contained herein or therein and supersedes any prior agreements, understandings, restrictions, representations, or warranties between the Grantee and the Company with respect to such subject matter other than those as set forth or provided for herein or therein. To the extent contemplated herein or therein, the provisions of any grant notice and the Agreement shall survive any settlement of the Award and shall remain in full force and effect.

If one or more of the provisions of this Agreement shall be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby and the invalid, illegal or unenforceable provisions shall be deemed null and void; however, to the extent permissible by law, any provisions which could be deemed null and void shall first be construed, interpreted or revised retroactively to permit this Agreement to be construed so as to foster the intent of this Agreement and the Plan

17. Counterparts. Any grant notice and this Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

18. Governing Law. This Agreement shall be interpreted and administered under the laws of the State of Delaware.

7

19. Other. The Grantee represents that the Grantee has read and is familiar with the provisions of the Plan and this Agreement, and hereby accepts the Award subject to all of their terms and conditions.

20. Section 409A Compliance. Section 409A of the Code imposes an additional 20% tax, plus interest, on payments from “non-qualified deferred compensation plans.” Certain payments under this Agreement could be considered to be payments under a “non-qualified deferred compensation plan.” The additional 20% tax, and interest, does not apply if the payment qualifies for an exception to the requirements of Section 409A or complies with the requirements of Section 409A. It is Company’s belief that the payments due pursuant to this Agreement shall qualify for the “short-term deferral” exception to 409A as set forth in Treasury Regulation Section § 1.409A-1(b)(4). Notwithstanding anything to the contrary in this Agreement, if the Company determines that the Grantee is a “specified employee” (as defined in Treas. Reg. § 1.409A-1(i)) and that payments to be provided to Grantee (i) are made on account of the Grantee’s Separation from Service, and (ii) are or may become subject to the additional 20% tax imposed under Section 409A, then such payments shall be paid on the first business day following the expiration of the six month period following the Grantee’s Separation from Service. For purposes of this Agreement, the term Separation from Service and Termination of Employment shall have the meaning set forth in Section 409A of the Code and the regulations and guidance issued thereunder.

21. Compliant Operation and Interpretation. The Company believes that the Agreement is not subject to the requirements of Section 409A of the Code, but it does not warrant or guaranty that the Agreement is either exempted from the requirements of Section 409A or that the Agreement complies with Section 409A. Employee remains solely responsible for any adverse tax consequences imposed upon him by Section 409A.

IN WITNESS WHEREOF, the Company has caused this Agreement to be signed by its duly authorized representative and the Grantee has signed this Agreement as of the date first written above.
