Amendment No. 1 to Employment Agreement with Donald Colvin



 Exhibit 10.4 
 Confidential Communication 
 AMENDMENT NO. 1 TO EMPLOYMENT AGREEMENT 
 WHEREAS, Semiconductor Components Industries, LLC (“Company”) and Donald Colvin (“Executive”) entered into an
Employment Agreement dates as of May 26, 2005 (“Agreement”); 
 WHEREAS, all defined terms used herein shall
have the meanings set forth in the Agreement unless specifically defined herein; 
 WHEREAS, the Agreement includes provisions
pertaining to Section 409A of the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”) which relates to non-qualified deferred compensation arrangements; 
 WHEREAS, one of the Internal Revenue Code Section 409A provisions in the Agreement requires that certain separation from service payments to
the Executive be delayed for six months; 
 WHEREAS, subsequent to the Executive entering into the Agreement with the Company the
final regulations under Internal Revenue Code Section 409A were issued and such final regulations clarified various aspects regarding this tax matter; 
 WHEREAS, now that the final regulations under Internal Revenue Code Section 409A have been issued and as a result of these final regulations, the Company and Executive wish to amend the Agreement to, among
other things, permit a distribution following the Executive’s separation from service (i.e., without a six month delay in payment) as permitted pursuant to the “separation pay exception” set forth in Treasury Regulation
Section 1.409A-1(b)(9) and to clarify certain other matters with respect to Internal Revenue Code Section 409A; and 
 WHEREAS, the Board of Directors of ON Semiconductor Corporation and its Compensation Committee have both reviewed and considered this matter and this Amendment No. 1 to the Agreement (“Amendment”). 

NOW, THEREFORE, for mutual consideration the receipt of which is hereby acknowledged, the Agreement is hereby amended as follows: 

1. Section 5(a) of the Agreement related to “Termination Payments” and “Without Cause” is hereby amended by replacing the
first sentence thereof with the following language, in order to, among other things, provide for the “separation pay exception” to Internal Revenue Code Section 409A: 
 “(a) Without Cause. In the event of the termination of the Executive’s employment during the Employment Period by the Company without
Cause (including a deemed termination without Cause as provided for in Section 3(f) (i.e., “Good Reason”)), the Executive shall be entitled to: (i) any accrued but unused vacation, (ii) Base Salary through the Date of
Termination (to the extent not theretofore paid), (iii) the continuation of Base Salary (as in effect immediately prior to the termination) for twelve (12) months 

  

 1 








 
following the Date of Termination which, subject to the restriction set forth below, shall be paid in accordance with the Company’s ordinary payroll
practices in effect from time to time, (iv) any earned but not paid Bonus for the Performance Cycle immediately preceding the Date of Termination, and (v) a pro-rata portion of the Bonus, if any, for the Performance Cycle in which the Date
of Termination occurs (based on the achievement of the applicable performance criteria and related to the applicable Performance Cycle as described in Section 2(b)). Notwithstanding the foregoing, the amount of payment set forth in
(iii) above during the six-month period following the Date of Termination shall not exceed the severance pay exception limitation amount set forth in Treasury Regulation Section 1.409A-1(b)(9)(iii)(A) (any amount subject to the separation
pay exception limitation shall be paid in a lump sum on the six-month anniversary of the Date of Termination). If the Company determines in good faith that the separation pay exception set forth in Treasury Regulation
Section 1.409A-1(b)(9)(iii)(A) does not apply as of the Date of Termination, the amount set forth in (iii) above shall be paid (a) in an initial lump sum equal to six months’ base salary (net of applicable taxes and withholdings)
on the six-month anniversary of the Date of Termination and (b) thereafter in installments in accordance with the Company’s ordinary payroll practices. The amounts set forth in (i) and (ii) above, shall be paid in accordance with
applicable law on the Date of Termination. The amounts set forth in (iv) and (v) above shall be paid as soon as is reasonably practicable after the close of the accounting books and records of the Company for the relevant Performance Cycle
at the same time bonuses are paid to other active employees, but in no event will payment be made for any Performance Cycle ending on December 31 before January 1 or after March 15 of the year following the year in which the
Performance Cycle ends. If payment by such date is administratively impracticable, payment may be made at a later date as permitted under Treasury Regulation Section 1.409A-1(b)(4)(ii).” 
 2. Section 5(c) of the Agreement related to “Termination Payments” and “Change in Control” is hereby amended by replacing the
first sentence thereof with the following language, in order to delete a proviso at the end of the first sentence related to Internal Revenue Code Section 409A which is no longer applicable: 
 “(c) Change in Control. If within twenty-four (24) months following a Change in Control (as defined herein), (i) the Company
terminates the Executive’s employment without Cause or (ii) the Executive terminates employment with the Company for Good Reason, then, in addition to all the other benefits provided to the Executive under Section 5(a) of this
Agreement, notwithstanding any provision in any applicable option grant agreement between the Company and the Executive: (A) any outstanding but unvested options granted on or prior to the Effective Date shall vest upon the Date of Termination;
and (B) all options (both vested and unvested) granted on or prior to the Effective Date will remain fully exercisable until the first to occur of (1) the one-year anniversary of the Date of Termination, and (2) the tenth anniversary
of the grant date of such option.” 
 3. Section 11 of the Agreement related to “Miscellaneous” shall be amended by
adding the following language at the end of Section 11 as a new subsection (l) with respect to the Internal Revenue Code Section 409A: 
  

 2 








 “(l) (i) Notwithstanding anything set forth herein to the contrary, no amount payable pursuant
to this Agreement on account of the Executive’s termination of employment which constitutes a “deferral of compensation” within the meaning of the Treasury Regulations issued pursuant to Section 409A of the Internal Revenue Code
(“Section 409A Regulations”) shall be paid unless and until the Executive has incurred a “separation from service” within the meaning of the Section 409A Regulations. Furthermore, to the extent that the Executive is a
“specified employee” within the meaning of the Section 409A Regulations as of the date of the Executive’s separation from service, no amount that constitutes a deferral of compensation that is payable on account of the
Executive’s separation from service shall be paid to the Executive before the date (“Delayed Payment Date”) which is the first day of the seventh month after the date of the Executive’s separation from service or, if
earlier, the date of the Executive’s death following such separation from service. All such amounts that would, but for this subsection, become payable prior to the Delayed Payment Date will be accumulated and paid on the Delayed Payment Date.

 (ii) The Company intends that income provided to Executive pursuant to this Agreement will not be subject to taxation under
Section 409A of the Internal Revenue Code. The provisions of this Agreement shall be interpreted and construed in favor of satisfying any applicable requirements of Section 409A of the Internal Revenue Code and the Section 409A
Regulations. However, the Company does not guarantee any particular tax effect for income provided to Executive pursuant to this Agreement. In any event, except for the Company’s responsibility to withhold applicable income and
employment taxes from compensation paid or provided to the Executive, the Company shall not be responsible for the payment of any applicable taxes on compensation paid or provided to the Executive pursuant to this Agreement.” 
 4. The provisions of this Amendment shall be effective as of the date written below (“Effective Date”), provided however, that the
Agreement shall be operated in good faith compliance with Internal Revenue Code Section 409A for periods beginning January 1, 2005 through the Effective Date. 
 5. This Amendment shall amend only the provisions of the Agreement as set forth herein. Those provisions of the Agreement not expressly amended shall be considered in full force and effect.
