Note B Organization
Registrant was originally organized on July 11, 1961 as a general partnership. On October 1, 2001, Registrant converted from a general partnership to a limited liability company under New York law and is now known as Empire State Building Associates L.L.C. The conversion did not change any aspect of the assets and operations of Registrant other than to protect its investors from any future liability to a third party.
Registrant’s members (“Members”) are Peter L. Malkin, Anthony E. Malkin and Thomas N. Keltner, Jr. (collectively, the “Agents”), each of whom also acts as an agent for holders of participations (“Participations”) in their respective member interest in Registrant (the “Participants”).
