Charter documents & Delaware law

The Company’s charter documents include provisions that may deter hostile takeovers, delay or prevent changes of control or changes in management, or limit the ability of stockholders to approve transactions that they may otherwise determine to be in their best interests. These include provisions prohibiting stockholders from acting by written consent, requiring 90 days advance notice for director nominations and stockholder proposals and granting the Company's Board of Directors the authority to issue up to 5,000 shares of preferred stock and to determine the rights and preferences of the preferred stock without the need for further stockholder approval.

The Company is also subject to Section 203 of the Delaware General Corporation Law which, subject to exceptions, prohibits the Company from engaging in any business combinations with any interested stockholder, as defined in that section, for a period of three years following the date on which that stockholder became an interested stockholder.
