VENTAS AND SUNRISE REIT ANNOUNCE

AMENDMENT TO PURCHASE AGREEMENT

Ventas to Acquire Sunrise REIT at Cdn $16.50 Per Unit in Cash

“Best and Final” Ventas Price is Recommended by Sunrise REIT Board

Special Meeting of Sunrise REIT Unitholders Scheduled for April 19, 2007

LOUISVILLE, KY and TORONTO, ON (April 11, 2007) – Ventas, Inc. (NYSE: VTR) (“Ventas”) and Sunrise Senior Living Real Estate Investment Trust (TSX: SZR.UN) (“Sunrise REIT”) announced today that they have agreed to amend the purchase agreement they entered into on January 14, 2007 to reflect an increase in the amount payable to unitholders of Sunrise REIT (“Unitholders”) from Cdn $15.00 per unit to Cdn $16.50 per unit. The total value of the transaction including debt is Cdn $2.28 billion (or approximately USD $1.97 billion). A copy of the amendment to the purchase agreement will be filed on SEDAR at www.sedar.com.

In connection with the amendment to the purchase agreement, the Sunrise REIT special meeting of Unitholders (“Special Meeting”) to consider the proposed transaction with Ventas has been scheduled for April 19, 2007 at 10:00 a.m. at the Toronto Stock Exchange. The record date for Unitholders entitled to vote at the meeting remains February 19, 2007 and the “outside date” for the transaction has been extended to June 30, 2007 from May 31, 2007.

Michael Warren, Chairman of Sunrise REIT and the Special Committee of the Sunrise REIT Board of Trustees formed to consider the transaction, said: “We are very pleased to be able to announce this amended transaction, which is an outstanding result for Unitholders. With Ventas’ 10% purchase price increase, the final price represents a premium of approximately 57% over the volume weighted average trading price of the REIT’s units (the “Units”) on the Toronto Stock Exchange (the “TSX”) for the 20-day period immediately preceding the announcement of the original transaction in January. The Sunrise REIT Special Committee and Board of Trustees strongly recommend that Unitholders vote FOR the proposed Ventas transaction at the upcoming Special Meeting.”

In connection with the amended purchase agreement, the Special Committee received an opinion from TD Securities Inc. that the consideration to be received by Unitholders in connection with the amended transaction is fair, from a financial point of view, to such Unitholders.

Debra A. Cafaro, Chairman, President and Chief Executive Officer of Ventas, said: “We continue to be excited about the Sunrise REIT portfolio and development pipeline which offer us diversification, high quality, private pay and growth benefits. It is important to underscore, however, that Cdn $16.50 is Ventas’ ‘best and final’ price; if we do not complete this transaction at this price, we will focus our attention on the other attractive acquisition opportunities in our pipeline.”

In addition, as a part of the amended terms, if the purchase agreement is terminated for any reason other than a breach by Ventas, Sunrise REIT has agreed to reimburse Ventas for up to Cdn $10 million in expenses. The amount of the break-up fee that may become payable under the purchase agreement in certain circumstances remains the same (and is not reduced by the expense reimbursement). The purchase agreement also contemplates that, conditioned on the closing of the transaction, Ventas and Sunrise REIT will settle the outstanding litigation that Ventas has filed against Sunrise REIT.

The closing of the transaction is expected to occur on or about April 26, 2007 (the “Closing Date”) pending approval of the Sunrise REIT Unitholders at the Special Meeting. It is the intention of Sunrise REIT to effect the redemption of all of the issued and outstanding Units as soon as possible on or after the Closing Date.

As previously announced, Sunrise REIT will pay normal monthly distributions of $0.0729 through March 2007 and a pro rata amount of Sunrise REIT’s regular monthly distribution for the period from April 1, 2007 up to but excluding the Closing Date.

The proposed transaction with Sunrise REIT will add 77 high-quality private pay assisted living communities in the U.S. and Canada to Ventas’ portfolio and includes the exclusive right of first offer to acquire other newly developed assets in Canada and portions of the U.S. The 77 communities are located in demographically desirable metropolitan areas of 19 states and two Canadian provinces. Ventas also expects to acquire for a fixed price two newly constructed communities in the U.S. and Canada in 2007 or 2008.

Sunrise Senior Living, Inc. (NYSE: SRZ) (“Sunrise”) developed most of the acquired Sunrise REIT assets and will remain as the manager of all of the properties under the existing long-term management contracts and is a minority joint venture partner in 59 of the communities.

Unitholders who have already voted FOR the proposed Ventas transaction need not take any action, for their votes will be counted. Those Unitholders who wish to change their vote
