Such indemnification shall be mandatory and not discretionary. The indemnification provided for herein shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any By-laws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. Any repeal or modification of this Article SEVENTH shall not adversely affect any right to indemnification of any persons existing at the time of such repeal or modification with respect to any matter occurring prior to such repeal or modification.

Such obligation to advance costs and expenses shall be mandatory, and not discretionary, and shall include, without limitation, costs and expenses incurred in asserting affirmative defenses, counterclaims and cross claims.
