except that, with respect to the occurrence of any of the events described in the second bullet point immediately above, so long as the Series B Preferred Stock remains outstanding with the terms of the Series B Preferred Stock materially unchanged, taking into account that, upon the occurrence of an event described in the second bullet point above, we may not be the surviving entity and the surviving entity may not be a corporation, the occurrence of such event will not be deemed to materially and adversely affect the rights, preferences, privileges or voting powers of the Series B Preferred Stock, and in such case such holders shall not have any voting rights with respect to the events described in the second bullet point immediately above.

If any event described in the second bullet point above would materially and adversely affect the rights, preferences, privileges or voting powers of the Series B Preferred Stock disproportionately relative to any other class or series of parity preferred stock, the affirmative vote of the holders of at least two-thirdsof the outstanding shares of the Series B Preferred Stock, voting as a separate class, will also be required. The following actions are not deemed to materially and adversely affect the rights, preferences, powers or privileges of the Series B Preferred Stock:

| • |     | any increase in the amount of our authorized Common Stock or preferred stock or the creation or issuance of
