February 26, 2013

To Fellow Participants in Empire State Building Associates L.L.C. (“ESBA”):

We are writing to alert you that a letter recently sent to you by Robert Machleder contains misinformation about your investment. Mr. Machleder is wrong on the facts and wrong on the law. It is our responsibility as your fiduciary and supervisor to address misinformation about the proposed transaction and the superior benefits and potential we believe it brings to every one of our investors.

Certain individuals have intentionally waited until the last minute, in some cases for years, to attempt to disrupt your vote. False arguments, no matter how artfully conveyed, remain wrong. This isn’t the first time that individuals have disseminated false or misleading information, and unfortunately it may not be the last. We want you to have the facts to make your choices on our proposals.

Last week, we spoke at length with Mr. Machleder about his assertion that the proposed consolidation does not trigger the overrides. We walked him through all the relevant documents and the law, and showed him that these override interests, which have been in place in some instances for more than two decades, are triggered by the proposed transaction.

For your convenience, we summarize below the key facts about the override interests. For any investor who is interested, we have prepared a memorandum which addresses the factual and legal basis for the overrides that was shared with Mr. Machleder as part of our conference with him. This memorandum can be reviewed on our website at www.EmpireStateRealtyTrust.com, just click on “Letters to Participants.”

First, what are the override interests? They are profit-sharing contracts under which Malkin Holdings is given a shared percentage (10%) of your ESBA profit distributions after return of full original investment.

Second, how were the overrides created? Years ago, Malkin Holdings circulated to ESBA investors individual, voluntary, binding contracts creating the override interests. No one was forced to sign the contracts, and those who did not consent are not affected. In the end, 94% of ESBA investors granted Malkin Holdings an override interest by voluntarily signing the contracts.

Third, what is the condition for payment of the overrides? Under the overrides, Malkin Holdings is to share in the proceeds of a “capital transaction.” By any definition, the proposals on which you have voted or are to vote constitute “capital transactions.”

To get the facts regarding our proposals, please use the following resources we have made available:



The prospectus/ consent solicitation we mailed to you which is part of the Form S-4 declared effective by the Securities and Exchange Commission.



The DVD that came with such mailing, which features Peter and Anthony Malkin hosting videos discussing the proposed transaction.



Our website at www.EmpireStateRealtyTrust.com, where new content is uploaded regularly, and where you can register for a conference call with us.



Our proxy solicitor, MacKenzie Partners, which you can call at 1-888-410-7850 to speak to a professional trained to answer your questions.



E-mail us at inquiries@MalkinHoldings.com with any question or for help in registering for a call or in filling out your consent form.

This very visible transaction attracts attention from many who may not have your interests at heart. We will not comment on all the misinformation of which we learn, but when we learn of incorrect assertions of a material nature, we will give you the facts.

We have always seen our investors as part of a family and have served you faithfully as supervisor and fiduciary for more than 75 years. We believe this transaction offers you tremendous benefits and improved prospects over the status quo. If you have not done so already, we urge that you vote “FOR” the proposals.

We hope you will call on us to help if we can assist you in any way.
