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

On December 13, 2012, Susan Wojcicki resigned as a member of the Board and the Compensation Committee of the Board, effective as of December 13, 2012. The resignation was not as a result of any disagreement with the Company. Rather, Ms. Wojcicki chose to resign due to time constraints and her need to focus on her significant responsibilities as senior vice president of product management and engineering for all advertising products at Google.

On December 13, 2012, the Board elected Tina Sharkey as a Class II member of the Board to fill the vacancy created as a result of the resignation of Ms. Wojcicki, and also appointed Ms. Sharkey to serve on the Compensation Committee.

The Board determined that Ms. Sharkey qualifies as an independent director under the director independence standards set forth in the rules and regulations of the Securities and Exchange Commission (“SEC”) and the applicable listing standards of the Nasdaq Stock Market (“Nasdaq Rules”) and satisfies the requirements for compensation committee members under the rules and regulations of the SEC and applicable Nasdaq Rules. The Board also determined that Ms. Sharkey is a “non-employee director” as such term is defined by the rules and regulations of the SEC.

Ms. Sharkey will be entitled to the compensation provided to other non-employee members of the Board and Audit Committee as described under the heading, “Director Compensation” in the Company’s Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on April 27, 2012, such description is incorporated into this Item 5.02 by reference.
