1934, as amended) of securities possessing more than fifty percent
(50%) of the total combined voting power of the Corporation's
outstanding securities pursuant to a tender or exchange offer made
directly to the Corporation's stockholders which the Board does not
recommend such stockholders to accept, or
(ii) a change in the composition of the Board over a
period of thirty-six (36) consecutive months or less such that a
majority of the Board members ceases by reason of one or more contested
elections for Board membership, to be comprised of individuals who
either (A) have been Board members continuously since the beginning of
such period or (B) have been elected or nominated for election as Board
members during such period by at least a majority of the Board members
