Re: Empire State Realty Trust, Inc.

To Participants in Empire State Building Associates L.L.C. and 60 East 42^nd St. Associates L.L.C.

Dear Fellow Participant:

As we have previously advised you, Malkin Holdings received indications of interest to purchase the fee and/or operating lease positions of the Empire State Building, as well as one indication of interest to purchase the fee and operating lease positions of One Grand Central Place (60 East 42^nd Street).

As fiduciaries, we review all matters concerning investment groups we serve. In our review of these indications of interest, we engaged Lazard Frères & Co. LLC as an independent financial advisor. After our review, we have concluded that it is in your best interest to proceed with the consolidation and IPO as approved by a supermajority of the Participants.

Sincerely,

MALKIN HOLDINGS LLC

/s/ Peter L. Malkin Peter L. Malkin Chairman /s/ Anthony E. Malkin Anthony E. Malkin President
