Charter documents and Delaware law description		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 of stockholder proposals or nominations to the Board of Directors and granting the Board of Directors the authority to issue up to five million 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 that, subject to exceptions, would prohibit 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. These restrictions may discourage, delay or prevent a change in the control of the Company
