 the board of directors and authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder. |

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or amended and restated bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented. Certificate of Incorporation and Bylaw Provisions Our amended and restated certificate of incorporation and our amended and restated bylaws include a number of provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management team, including the following:

| • |     | Board of Directors Vacancies. Our amended and restated certificate of incorporation and amended and                                                                                                                                                    
 restated bylaws authorize our board of directors to fill vacant directorships, including newly-created seats. In addition, the number of directors constituting our board of directors may be set only by resolution adopted by a majority vote of our 
 entire board of directors. These provisions prevent a stockholder from increasing the size of our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees;                           |

| • |     | Classified Board. Our amended and restated certificate of incorporation and amended and restated                                                                                                                                                        
 bylaws provide that our board of directors is classified into three classes of directors, each of which hold office for a three-year term. In addition, directors may only be removed from the board of directors for cause and only by the approval of 
 66 2/3% of our then-outstanding shares of our capital stock entitled to vote thereon. A third party may be discouraged from making a tender offer or otherwise attempting to obtain control of us as it is more difficult and time consuming for        
 stockholders to replace a majority of the directors on a classified board of directors;                                                                                                                                                                 |

| • |     | Stockholder Action; Special Meeting of Stockholders. Our amended and restated certificate of                                                                                                                                                              
 incorporation provide that stockholders are not able to take action by written consent, and are only able to take action at annual or special meetings of our stockholders. Stockholders are not be permitted to cumulate their votes for the election of 
 directors. Our amended and rest
