(4)	(Continued Footnote 3)In the event of an Acquiror Sale in which the per share consideration received is less than a price target set forth in the Merger Agreement that has not previously occurred, the applicable provisions of the Sponsor Support Agreement will terminate and no Earn Out Shares will be issuable thereunder with respect to such price target in connection with or following completion of such Acquiror Sale.
