CALEAST INDUSTRIAL INVESTORS TO ACQUIRE CENTERPOINT PROPERTIES TRUST

CHICAGO, December 7, 2005 – CenterPoint Properties Trust (NYSE:CNT) (“CenterPoint”), the California Public Employees’ Retirement System (“CalPERS”) and LaSalle Investment Management (“LaSalle”) today announced that CalEast Industrial Investors LLC (“CalEast”) and CenterPoint reached a definitive agreement whereby CalEast will acquire CenterPoint for $50 per common share in cash.

CenterPoint is a publicly traded real estate investment trust (REIT) and the largest industrial property company in the 1.4-billion-square-foot Chicago regional market. CalEast is a leading investor in logistics warehouse and related real estate whose members include CalPERS and LaSalle. LaSalle, the investment management business of Jones Lang LaSalle (NYSE:JLL), serves as the managing member of CalEast. Since 1999, CenterPoint and CalEast have partnered in a joint venture known as CenterPoint Venture LLC, which acquires, develops, manages and sells industrial property.

The per share purchase price represents a 9.1% premium over CenterPoint’s closing share price on December 7, 2005, and a 13.1% premium to the average closing price over the past three months. The total consideration is approximately $3.4 billion, which includes the assumption of CenterPoint’s debt and preferred stock. CenterPoint expects to continue to pay regular common dividends, which are expected to be increased 8.2% to $0.4625 per quarter for 2006. CenterPoint’s 7.5% Series B convertible preferred shares will remain outstanding after the merger, but in accordance with their terms will become convertible into the merger consideration, without interest.  CenterPoint’s Series D Preferred Shares, which are not convertible, will continue to be outstanding after the merger as well.

Completion of the transaction, which is expected to occur in March or April of 2006, is subject to approval by CenterPoint’s common shareholders and certain other customary conditions. Completion of the merger is not subject to the receipt of financing by CalEast.  CalPERS and Jones Lang LaSalle have subscribed to additional equity in CalEast to fund this transaction.  This transaction has been unanimously approved by CenterPoint’s Board of Trustees.

“This transaction maximizes value for shareholders as an all cash sale with no financing contingency.  The price achieved reflects the significant value of the operating platform that we have created,” said Mike Mullen, Chief Executive Officer of CenterPoint.

“Through CalEast’s acquisition of CenterPoint, we gain access to an attractive warehouse portfolio, a high quality land bank, and an outstanding management team that has played a pioneering role in the rapidly emerging intermodal logistics industry,” said Lynn Thurber, Chief Executive Officer of LaSalle Investment Management. “We look forward to the CenterPoint management team’s continued leadership of the company.”

“Rapid growth in global trade is driving significant change in the warehouse requirements and logistics strategies of companies around the world,” said Mike McCook, Senior Investment Officer – Real Estate of CalPERS. “CalEast has had a property joint venture with CenterPoint for six years, during which time we have come to know the company and its management team well.  We believe that CenterPoint is very well positioned to capitalize on the continuing modernization of the global supply chain.”

Wachovia Securities acted as financial advisor to CenterPoint, and Kirkland & Ellis LLP provided legal advice to the company.  Morgan Stanley acted as financial advisor to CalEast and Jones Day provided legal advice to the company.

In the 2004 Annual Report, we emphasized that with every investment CenterPoint Properties makes, we take a long-term view of the total return the Company can create.  In 2005, we have followed this strategy of creating high growth opportunities through long-term investments.

Today, our Board of Trustees made a decision that we believe will benefit the company, our associates and shareholders alike. Attached to this memo you will find the press release regarding this transaction.  However, I wanted to personally communicate this with you because without our associates, this arrangement would not have been possible.

I’m very pleased to announce that CenterPoint’s Board of Trustees unanimously approved an agreement whereby CalEast Industrial Investors, LLC. (CalEast), will be acquiring CenterPoint Properties Trust for $50 per share, subject to approval by the Company’s common shareholders and certain other customary conditions.  The expectation is that the contract will close in March or April, making CenterPoint Properties a privately held company.  As many of you are aware, one of CenterPoint’s most successful ventures has been with CalEast.  They are a leading investor in logistics, warehouse and related commercial real estate whose members include the California Public Employees’ Retirement System (CALPERS) and LaSalle Investment Management (“LaSalle”).   LaSalle serves as managing member of CalEast.

I’m quite certain that each of you will have many questions regarding this announcement and how it might affect you.  In an effort to help provide answers, Paul and I will hold an “All Associate” meeting tomorrow morning at 10:00am in the cafeteria.  I realize this is short notice, but because of the significance of this announcement, it is important that everyone is present.  In addition to tomorrow’s meeting, CenterPoint will also hold small group meetings sometime next month to ensure your questions are answered and concerns are addressed.  In some instances we may not be in a position to answer some of your questions.  However we will try to give you as much information as we can over the next several weeks.

On a more personal note, I am very excited about the opportunities this deal will bring to the Company, however it is not yet a “done deal”.  I know CenterPoint would not be what it is today without our most highly valued asset, our wonderful and dedicated associates.  You may be interested in knowing that CalEast has told me on numerous occasions that they believe CenterPoint’s most valuable assets “drive home” every night.  I look forward to visiting with you tomorrow.
