                  forth in an initial Bylaw or in a Bylaw adopted by the
                  stockholders entitled to vote of the corporation unless
                  provisions for such classification shall be set forth in this
                  certificate of incorporation.

directors pursuant to the provisions of this Certificate of Incorporation, the
by-laws of the Corporation or as may be permitted by the General Corporation Law
of the State of Delaware.
