[Empire State Building Associates L.L.C. Letter]

[MH letterhead]

May 15, 2013

Re: Empire State Realty Trust, Inc.

As we celebrate the 82nd anniversary of the opening of the Empire State Building, we write to update you on progress in obtaining investor consents and court rulings. The solicitation period remains open until we announce its termination.

Report on our Receipt of Consents

As of the close of business on May 15, we have received approximately 99.3% of the votes needed from Empire State Building Associates L.L.C. (“Associates”) to approve the consolidation and IPO. As of such date, approximately 91.8% of all interests have voted.

 

Entity

   Total Vote For Transaction     Required Vote

Empire State Building Associates

     79.6 %    80% per group

In Associates’ participating group #2, more than the required 80% supermajority has approved the transaction, and we are at this time permitted to close the solicitation and send the buyout notice for that group to give its non-consenting participants ten days to consent, if they wish to avoid a buyout. We have not yet closed the solicitation or sent such buyout notice in such group.

More detail and important information regarding voting on the consolidation and third party portfolio sale proposals in the three public entities follows below.

Buyout Provisions Ruling

On April 30, the court ruled against the claims brought to block the buyout of a non-consenting participant for $100 if such participant does not consent after notice that the supermajority has approved the recommended program. The court ruled that the buyout provision in your 1961 participating agreements is legally binding and enforceable.

Thus, your interest is subject to purchase by Associates for a price of $100 unless you vote in favor of the consolidation or third party portfolio transaction proposal, as applicable, within ten days after receipt of notice that the required 80% supermajority consent has been received for such proposal in your participating group. As of the date of this letter, we have not sent any such notice to any of the participating groups.


Class Action Settlement Ruling

At the hearing on the matter on May 2, presiding Justice Sherwood stated “it is the court’s intention to approve the settlement” with regard to the September 28, 2012 full settlement of the class action. The judge’s written ruling is still pending.

FOR NON-VOTERS & THOSE WHO VOTED “AGAINST” OR “ABSTAIN”:

[ One Time Distribution and Payment to Participants

Should the consent for consolidation, REIT formation, and IPO be approved and occur, based on the cash reserves and transaction expenses at September 30, 2012, we estimate you will receive on account of your participation interest $[information to be inserted in individual letters] as your share of such settlement proceeds, plus $[information to be inserted in individual letters] as your share of reimbursement for transaction expenses and excess cash reservesall in addition to your election of OP units and common stock and your share of additional rent to be paid by Empire State Building Company L.L.C., the operating lessee, based upon it profit for the lease year ending on the date of the IPO.]

Additional Consent Related Information

As of the close of business on May 15, we have also received approximately 98.8% of the votes needed to approve the transaction in 60 East 42nd St. Associates L.L.C. and more than the required votes to approve it in 250 East 57th St. Associates L.L.C.

Each of the operating lessees of Empire State Building, One Grand Central Place/ 60 East 42nd (formerly called the Lincoln Building), and 250 West 57th Street have already been authorized to be included in the consolidation and IPO. Should the IPO go forward, the operating lease of One Grand Central Place will be included, regardless of whether the fee position vote is received.

FOR NON-VOTERS:

[Our records indicate you have not yet returned your consent ballot. Your failure to vote is counted as voting “AGAINST” the proposal. We ask you now to consider promptly submitting a ballot voting “FOR” the transaction.

Further, your failure to submit the related tax form may subject you to unfavorable tax withholding. We ask you also now to consider promptly submitting your tax form in addition to your ballot.

To assist you in timely response, we have pre-printed information for you from our records and tabbed the forms where you need to mark your choices and sign. We urge you now to join the overwhelming majority of your fellow investors by taking a few minutes to complete and return these forms, which are enclosed for your convenience:

Personalized tax form. We have pre-printed your current address, Social Security Number, and absence of withholding, so you need only confirm and sign where tabbed.


Consent ballot. We have tabbed each item where you should mark “FOR” or “AGAINST” and sign.

Voting “FOR” the transaction is the essential first step toward your receiving the transaction’s many benefits, and the sooner the proposed transaction is approved, the sooner the expenses and disruption to all investors may be brought to an end, and investors can receive reimbursement for the costs of the transaction, excess cash reserves, and the class action settlement proceeds.

Please feel free to call either of us at 212-850-2660 or e-mail us at inquiries@MalkinHoldings.com with any question.]

FOR VOTERS WHO HAVE VOTED “AGAINST” OR “ABSTAIN”:

[You have voted “AGAINST” or “ABSTAIN”. We ask you now to consider changing your vote.

For your convenience, we have enclosed a duplicate ballot and return envelope.

Voting “FOR” the transaction is the essential first step toward all investors’ receiving the transaction’s many benefits, and the sooner the proposed transaction is approved, the sooner the expenses and disruption to all investors may be brought to an end, and investors can receive reimbursement for the costs of the transaction, excess cash reserves, and the class action settlement proceeds.
