(a) – (d) Not applicable.

(e) On February 12, 2007, the Compensation Committee (“Committee”) of the Board of Directors of ON Semiconductor Corporation (“Corporation”) determined and approved specific financial and operational performance goals for the first half of 2007 for possible bonus awards for specific individuals, including certain senior officers of the Corporation (“Executive Officers”). Actual bonuses will be determined based on achievement of these goals. Similar to the awards for the second half of 2006, bonuses for the first half of 2007 will be paid only if the Corporation achieves a certain minimum Earnings Before Income Taxes, Depreciation and Amortization (“EBITDA”) amount. If this EBITDA amount is attained, the bonus of Keith Jackson, President and Chief Executive Officer of the Corporation, will be based on EBITDA and the following performance criteria of the Corporation: a total revenue goal; a new product revenue goal; a strategic accounts revenue goal; and a gross margin goal. If these goals are achieved, Mr. Jackson’s bonus award would be expected to be approximately 100% of his base salary for the first half of 2007 with the possibility of a maximum bonus of approximately 225% of his base salary for the period. If the minimum EBITDA amount is attained, the other Executive Officers of the Corporation will receive bonuses based on many of the same or similar factors as for Mr. Jackson with the applicable percentage determined for each individual by the Committee. The remainder of the other Executive Officers’ bonus awards will be based on measurable goals related to the applicable business group or area, or functional responsibility for each executive. If these goals are achieved, the bonus awards for the other Executive Officers would be expected to be in the range of approximately 50% to 65% of the applicable base salary for the first half of 2007 with the possibility of maximum bonuses in the range of approximately 113% to 146% of base salary for the first half of 2007. In addition to Mr. Jackson, the other Executive Officers are: Donald Colvin, Executive Vice President and Chief Financial Officer; William George, Executive Vice President, Operations; Robert Mahoney, Executive Vice President of Sales and Marketing; George H. Cave, Senior Vice President, General Counsel, Chief Compliance and Ethics Officer and Secretary; William Hall, Senior Vice President and General Manager, Standard Products Group; William Schromm, Senior Vice President and General Manager, Computing Products Group; and Michael (Andy) Williams, Senior Vice President and General Manager, Automotive and Power Regulation Group. The bonus awards for each of the Executives Officers are expected to be paid pursuant to the Corporation’s 2007 Executive Incentive Plan, as amended from time-to-time.

(f) Not applicable.
