EQUITY RESIDENTIAL (EQR)

Any and All of Certain of its Outstanding Notes

Chicago, IL –December 2, 2009 – Equity Residential (NYSE: EQR) today announced that its operating partnership, ERP Operating Limited Partnership (the “Operating Partnership”), has commenced two cash tender offers for any and all of the series of its notes listed in the table below (collectively, the “Notes”). The offers to purchase consist of two separate offers (each an “Offer” and together, the “Offers”), with one offer to purchase any and all of the outstanding Notes listed under the heading “Non-Exchangeable Notes Offer” in the table below (the “Non-Exchangeable Notes Offer”) and a second offer to purchase any and all of the outstanding Notes listed under the heading “Exchangeable Notes Offer” in the table below (the “Exchangeable Notes Offer”).

The purpose of the Offers is to utilize the more than $400 million of unrestricted cash on hand and available borrowings from the Operating Partnership’s undrawn revolving credit facility to retire the Notes prior to their maturity in order to reduce debt maturities and lower the Operating Partnership’s future interest expense.

With approximately $250 million in 1031 exchange funds, the revolving credit facility, funds from continuing property dispositions and an untapped ATM share offering program, Equity Residential believes that it remains well-positioned to take advantage of future opportunities to add high-quality assets to its portfolio.

The consideration payable per $1,000 principal amount of each series of the Notes will include the amount set forth in the table below under the column entitled “Total Consideration” plus the accrued and unpaid interest to, but not including, the respective settlement date for the Notes purchased in each Offer. The settlement date for the Non-Exchangeable Notes Offer shall occur promptly following the Non-Exchangeable Notes Offer Expiration Date (as defined below) and is expected to be December 10, 2009. The settlement date for the Exchangeable Notes Offer shall occur promptly following the Exchangeable Notes Offer Expiration Date (as defined below) and is expected to be December 31, 2009. Additional terms and conditions of the Offer are set forth in the Offer to Purchase dated December 2, 2009 (the “Offer to Purchase”) and the related Letter of Transmittal (the “Letter of Transmittal”).

The Non-Exchangeable Notes Offer will expire at 5:00 p.m., New York City time, on December 9, 2009, unless extended (such date and time, as the same may be extended, the “Non-Exchangeable Notes Offer Expiration Date”) and the Exchangeable Notes Offer will expire at 12:00 midnight, New York City time, on December 30, 2009 unless extended (such date and time, as the same may be extended, the “Exchangeable Notes Offer Expiration Date”). The Non-Exchangeable Notes Offer Expiration Date and the Exchangeable Notes Offer Expiration Date are each referred to as an “Expiration Date.” Under certain circumstances, and as more fully described in the Offer to Purchase, the Operating Partnership may terminate either Offer before the applicable Expiration Date. Any tendered Notes may be withdrawn prior to, but not after, the applicable withdrawal date and withdrawn Notes may be re-tendered by a holder at any time prior to the applicable Expiration Date.

This press release is neither an offer to purchase nor a solicitation to buy any of these Notes nor is it a solicitation for acceptance of the Offers. The Operating Partnership is making the Offers only by, and pursuant to the terms of, the Offer to Purchase and the related Letter of Transmittal. The Offers are not being made in any jurisdiction in which the making or acceptance thereof would not be in compliance with the securities, blue sky or other laws of such jurisdiction. None of the Operating Partnership, Equity Residential, the Dealer Manager, the Depositary, the Information Agent for the Offers or the Trustee for the Notes makes any recommendation in connection with the Offers.
