 of our stockholders. The voting agreement will terminate upon the completion of this offering, after which there will be no further contractual obligations regarding the election or designation of our directors. Our current directors will continue to serve as directors until their resignation, removal or successor is duly elected. In accordance with the terms of our amended and restated certificate of incorporation that will become effective immediately prior to the closing of this offering, we will divide our board of directors into three classes, Class I, Class II, and Class III, with members of each class serving a staggered three-year term. In connection with this offering, our board of directors will be divided into the following three classes:

| • |     | Class I, which will consist of    and    , whose terms will      
 expire at our annual meeting of stockholders to be held in 2026; |

| • |     | Class II, which will consist of    and    , whose terms will         
 expire at our annual meeting of stockholders to be held in 2027; and |

| • |     | Class III, which will consist of    and    , whose terms              
 will expire at our annual meeting of stockholders to be held in 2028. |

At each annual meeting of stockholders to be held after the initial classification, the successors to directors whose terms then expire will serve until the third annual meeting following their election and until their successors are duly elected and qualified. Our amended and restated bylaws that will become effective immediately prior to the closing of this offering will provide that the authorized number of directors may be changed only by resolution of a majority of our board of directors. Any additional directorships resulting from an increase in the number of directors or from the filling of any current vacancies will be distributed between the three classes so that, as nearly as possible, each class will consist of one-third ofthe directors. This classification of our board of directors may have the effect of delaying or preventing changes in our control or management. Director Independence Our board of directors has undertaken a review of the independence of our directors and considered whether any director has a relationship that, in the opinion of the board of directors, would interfere with the exercise of 179

independent judgment in carrying out the responsibilities of a member of our board. Based upon information requested from and provided by each director
