[MH Letterhead]

April 10, 2013

To Fellow Participants in 60 East 42nd St. Associates L.L.C. (“Associates”):

Robert W. Gelfman (“Gelfman”) sent participants a letter regarding an override granted by Associates’ participants to Malkin Holdings in 1968. We responded previously, highlighting what we believe are Gelfman’s errors on the facts and the law and his misquoting of the relevant documents in a way we feel materially distorts the agreements. Gelfman has since written again, seeking to dismiss his misquote as “unintentional.”

We enclose an unsolicited e-mail we received from a fellow investor in Associates who forwarded to us his email to Gelfman on this subject. Mr. Leder has no business or family relationship with Malkin Holdings. We think his words speak volumes and share them with you with his permission.

We believe we have correctly stated our position in our prior response to Gelfman’s writing, and we do not intend to send additional writing on the matter.

The vote remains open, and we continue to receive new consents. If you have not yet voted FOR the proposals, we urge you to do so. The best way to ensure that you receive the transaction’s many benefits and reduce ongoing solicitation cost is to complete and return your consent form today.

Please call our proxy solicitation agent, MacKenzie Partners, at 1-888-410-7850 or e-mail us at inquiries@MalkinHoldings.com if you have any question.

Dear Peter and Tony,

Thought I’d forward the e-mail I just sent to Robert Gelfman. If you care to send it to the participants of 60 E 42 St Associates, feel free to do.

Dear Mr. Gelfman,

I am an investor in 60 E 42nd St Associates and wish to comment on your letter to Associates dated March 30, 2013. While I, like all participants, would like not to pay the 10% override if the consolidation goes through, unfortunately I cannot agree with your position that it does not apply in this case.

Quoting from page two of the letter to participants from Larry Wien dated February 26, 1968, after proposing that all distributions to participants in excess of 14% be allocated 90% to participants and 10% to Wien, Lane, Klein & Malkin, the beginning of the next sentence states “While such arrangement may permit Wien, Lane, Klein & Malkin to participate in future profits without making an investment in Associates”. Notice that the word used is “profits”, not “operating profits” as you state in your letter.

Clearly the consolidation as proposed is generating profits for the participants. We are to receive stock and/or operating units valued at over $400,000 for each $10,000 unit we are contributing to the REIT. If this doesn’t represent profit I don’t know what does. Yes it would be nice to receive more, but from what I read that is not the case.

By the way, in case you are interested in my qualifications, I have been a real estate investor for almost 40 years and have served as a financial analyst for a commercial real estate developer who owned and managed office buildings. I believe the REIT gives investors the best opportunity to maximize their investment in the Lincoln Building and the other properties in the consolidation (I hold interests in several of these properties), and I have voted for the consolidation.
