Advance Notice Requirements for Shareholder Proposals and Director Nominations. Our Bylaws provide advance notice procedures for shareholders seeking to bring business before our annual meeting of shareholders or to nominate candidates for election as directors at our annual meeting of shareholders and specify certain requirements regarding the form and content of a shareholder’s notice. These provisions might preclude our shareholders from bringing matters before our annual meeting of shareholders or from making nominations for directors at our annual meeting of shareholders if the proper procedures are not followed.

Additional Authorized Shares of Capital Stock. The additional shares of authorized common stock and preferred stock available for issuance under our Certificate of Incorporation, could be issued at such times, under such circumstances and with such terms and conditions as to impede a change in control.

Exclusive Forum. Our Bylaws provide that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware, to the fullest extent permitted by law, is the sole and exclusive forum for (a) any derivative action or proceeding brought on our behalf, (b) any action asserting a claim of breach of a fiduciary duty owed by, or other wrongdoing by, any director, officer, stockholder, employee or agent of us to us or our stockholders, (c) any action asserting a claim against us arising pursuant to the DGCL, our Certificate of Incorporation or Bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, (d) any action to interpret, apply, enforce or determine the validity of our Certificate of Incorporation or Bylaws, or (e) any action asserting a claim against us that is governed by the internal affairs doctrine. Our Bylaws further provide that unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Nothing in the exclusive forum provisions of our Bylaws affects suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction.

The Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. We have opted out and are not subject to the provisions of Section 203 of the DGCL.
