President Compensation Agreement
On May 17, 2013, the Compensation Committee of the Board of Directors of Silicon Laboratories Inc. ("Silicon Laboratories") approved the terms of compensation for its President, Bill Bock. The Committee approved the following compensation for Mr. Bock, upon the effective date of his appointment: (a) an annual base salary of $375,000, (b) an annual target bonus as a percentage of his base salary of 100% under the 2013 Bonus Plan, (c) a grant of 35,000 Restricted Stock Units (the "RSU Award") that shall vest as follows: 50% on June 30, 2015 and 50% on June 30, 2016, contingent upon Mr. Bock's continued service as an employee of Silicon Laboratories through each such date, and (d) a grant of 25,000 Market Stock Units (the "MSU Award") that shall vest on July 31, 2016, contingent upon his continued service as an employee of Silicon Laboratories through such date. The actual number of shares to be awarded pursuant to MSU Award shall be determined based upon the performance of Silicon Laboratories' stock price relative to the Philadelphia Semiconductor Sector Total Return Index over a three year period commencing as of July 1, 2013 (the "Performance Period"). Bonuses paid to Mr. Bock will be pro rated according to the time he was employed by Silicon Laboratories during the applicable period.
Following Mr. Bock's termination of service as an employee (such date of termination, the "Termination Date") and contingent upon his continued service as a member of Silicon Laboratories' Board of Directors, he will:
(a) be granted an additional award of Restricted Stock Units with a grant date value as of the Termination Date equal to $12,500 multiplied by the number of months remaining until the first annual stockholders meeting following the Termination Date (with partial months rounded up) and such grant would vest in a lump sum on the date of the first annual stockholders meeting following such Termination Date;
(b) be entitled to a cash payment with respect to each Eligible RSU Award equal to (i) the Fair Market Value of a share of Silicon Laboratories' common stock on the Termination Date multiplied by (ii) the number of unvested Restricted Stock Units subject to such Eligible RSU Award that would have vested within 12 months of the Termination Date multiplied by (iii) a fraction equal to the number of months (with partial months rounded up) that he has served as an employee between the later of the effective date of grant of the Eligible RSU Award or the last vesting date of such Eligible RSU Award (such later date, the "
Starting Date
") and the Termination Date divided by the total number of months between the Starting Date and the applicable scheduled vesting date; and
(c) be entitled to a cash payment with respect to each Eligible MSU Award equal to (i) the Fair Market Value of a share of Silicon Laboratories' common stock on the Termination Date multiplied by (ii) the Target Number of Units subject to such Eligible MSU Award multiplied by (iii) a fraction equal to the number of months (with partial months rounded up) that he has served as an employee since the beginning of the applicable Performance Period divided by the total number of months in the Performance Period multiplied by the Relative Return Factor.  For purpose of this calculation, the ending date of the Performance Period shall be the Termination Date.
The term "Eligible RSU Award" shall mean the RSU Award and any future award of Restricted Stock Units, but shall not include any currently outstanding award of Restricted Stock Units.
The term "Eligible MSU Award" shall mean the MSU Award and any future award of Market Stock Units, but shall not include any currently outstanding award of Market Stock Units.
Furthermore, the general requirement that a non-employee director must not have been employed by Silicon Laboratories for at least 6 months prior to the date of an annual stockholders meeting in order to receive the $150,000 Restricted Stock Unit grant shall not be applicable to Mr. Bock (for clarity, Mr. Bock must still be a non-employee director on the date of such meeting in order to receive such grant).
