Our business affairs are managed under the direction of our board of directors, which is currently composed of
eight members. All of our directors, other than Mr. Costolo, our chief executive officer, are independent within the

staggered classes of directors. At each annual meeting of stockholders, a class of directors will be elected for a threeyear
term to succeed the class whose term is then expiring
