          With respect to decisions to be made concerning the unwinding of the transaction
          with the NJSEA, the parties agree that they will cooperate and seek to reach a
          mutual decision whether to continue to pursue the transaction or to unwind. If
          there is an involuntary unwind due to injunctive or other relief, beyond all
          reasonable legal remedies that the Partnership can pursue, then the transaction
          will be unwound and any cash proceeds or other assets will be distributed
          according to paragraph 1 above. If the transaction is otherwise unwound over the
          objections of Mack-Cali then any cash or other assets will be distributed
          according to paragraph 1 above and Mills will either (i) pay to Mack-Cali the
          M-C Invested Capital, or (ii) assign over to Mack-Cali all of Mill&#146;s right,
          title and interest in and to the project. </FONT></P>
