Item 5.02. Departure of Directors and Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On October 11, 2010, Synaptics Incorporated (the “Company”) announced the appointment of Russell J. Knittel as Interim President and Chief Executive Officer following the resignation for personal reasons of Thomas J. Tiernan as President, Chief Executive Officer, and a director. Mr. Knittel will also be joining the Board of Directors. The Board of Directors is instituting an immediate search for a successor President and Chief Executive Officer.

In connection with Mr. Tiernan leaving the Company, the Company and Mr. Tiernan entered into a Separation Agreement and Release. In exchange for Mr. Tiernan executing a general release of claims he may have against the Company and agreeing not to directly or indirectly solicit employees or prospective acquisition candidates for a 12-month period and not use the Company’s trade secrets or confidential information to solicit customers, manufacturers, or manufacturer’s representatives, the Company agreed, for a period of 12 months, to continue to pay Mr. Tiernan’s $475,000 base salary, to continue to vest his stock options and restricted stock units, and to pay premiums for continued health insurance benefits, life insurance, and disability coverage to which the Company’s employees are entitled, and, in two equal payments, to pay his $475,000 targeted bonus. In addition, Mr. Tiernan’s currently vested stock options will be exercisable for a period of 15 months. Mr. Tiernan has withdrawn as a nominee for election to the Company’s Board of Directors, which election will be conducted at the annual meeting of stockholders of the Company to be held on October 19, 2010.

The Company agreed to pay to Mr. Knittel on a pro rata basis, a base salary at the same $475,000 annual rate as was being paid to Mr. Tiernan, plus a bonus equal to the higher of his base salary or a performance bonus pursuant to the Company’s performance-based bonus plan. In addition, the Company granted Mr. Knittel stock options to purchase 131,100 shares of common stock vesting on the earlier of the successful recruitment of a successor President and Chief Executive Officer or one year. There are no other arrangements or understandings pursuant to which Mr. Knittel was selected as Interim President and Chief Executive Officer. There are no family relationships among any of our directors, executive officers, and Mr. Knittel. There are no related party transactions between the Company and Mr. Knittel reportable under Item 404(a) of Regulation S-K.

The foregoing summary of the Separation Agreement and Release does not purport to be complete and is qualified in its entirety by reference to the Separation Agreement and Release, which is filed hereto as Exhibit 10.24 and is incorporated herein by reference.

On October 11, 2010, the Company issued a press release announcing Mr. Knittel’s appointment and Mr. Tiernan’s departure.
