Anti-Takeover Effects of Provisions of Delaware Law and our Organizational Documents Certain provisions of Delaware law as well as our organizational documents, which are summarized below, may have the effect of delaying, deferring, or discouraging another person from acquiring control of the Company. They are also designed, in part, to encourage persons seeking to acquire control of the Company to negotiate first with the Board. We believe that the benefits of increased protection of the Company’s potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire the Company because negotiation of these proposals could result in an improvement of their terms. Section 203 and Business Combinations We have opted out of Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder. However, our certificate of incorporation includes a prohibition on such business combinations with interested stockholders, with the following exceptions:

| • |     | the business combination or transaction which resulted in the stockholder becoming an interested stockholder was 
 approved by the Board prior to the time that the stockholder became an interested stockholder;                   |

| • |     | upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the                                                                                                                                    
 interested stockholder owned at least 85% of the Company’s voting stock outstanding at the time the transaction commenced
