Unless the Corporation consents in writing to the selection of an alternative forum, the Circuit Court for Baltimore City, Maryland, or, if that Court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, shall, to the fullest extent permitted by law, be the sole and exclusive forum for (a) any Internal Corporate Claim, as such term is defined in Section 1-101(p) of the MGCL, or any successor provision thereof, (b) any derivative action or proceeding brought on behalf of the Corporation, (c) any action asserting a claim of breach of any duty owed by any director, officer or employee of the Corporation to the Corporation or to the stockholders of the Corporation, (d) any action asserting a claim against the Corporation or any director, officer or employee of the Corporation arising pursuant to any provision of the MGCL or the Charter or these Bylaws, or (e) any other action asserting a claim against the Corporation or any director, officer or employee of the Corporation that is governed by the internal affairs doctrine. If any action the subject matter of which is within the scope of the preceding sentence is filed in a court other than a court located within the State of Maryland (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (a) the personal jurisdiction of the state and federal courts located within the State of Maryland in connection with any action brought in any such court to enforce the preceding sentence and (b) having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.
