such collateral or part thereof; or (ii) instruct, direct and cause Assignor to

direction of the Holders) be entitled to sue for, enforce payment of and receive
any and all amounts then and at any time remaining due from Assignor or the
Partnership for principal and interest on the Senior Partnership Note, or other
sums due under the Senior Note Mortgage or the Senior Note Indenture, as the
case may be, or otherwise

institute and maintain or cause in the name of Assignor or Assignee or both to
be instituted and maintained such suits and proceedings as Assignee may be
advised by its counsel shall be necessary and appropriate to prevent any
impairment of the Assigned Properties, or any of them, and to protect its
interests in the Assigned Properties, and in the rents, issues, rights, revenues
