CenterPoint Provides Update on Portfolio Sale.

Business Editors

OAK BROOK, Ill.--(BUSINESS WIRE)--May 13, 2004

CenterPoint Properties Trust (NYSE:CNT) today announced that it continues to negotiate the $400-500 million portfolio sale (see April 14, 2004 press release). While the proposed buyer, American Industrial Trust ("AIT"), has not finalized all of its funding for the acquisition, there continue to be discussions with a number of interested investors. However, there can be there can be no assurance that all or any part of the transaction will close.

The delay in funding of the acquisition can be attributed to the dramatic increase in interest rates and the significant weakening of the Australian dollar. In addition, the Australian IPO market has been disrupted by a significant merger involving several Westfield entities, which would dramatically alter the composition of the market for publicly traded property company shares. If completed, the recently proposed Westfield three-part merger and IPO would create Australia's eighth largest publicly traded entity and one of the world's largest property companies. Until the details of the flotation are known and the proposed offering is finalized, the Westfield deal has sidelined considerable investment and index fund capital.

"CenterPoint never included the AIT portfolio sale in its guidance, nor has it ever modified its 2004 or future business plans for the potentiality of the deal. Therefore, CenterPoint remains ahead of 2004 plan and budget in virtually all areas of its business," stated John Gates, Jr., Co-Chairman and CEO.

"As always, the disposition market for Chicago industrial property remains large, liquid, diverse and very fragmented. Indeed, CenterPoint fully expects to meet or exceed its 2004 and 2005 disposition targets - with or without - the AIT transaction. 'One-stop shopping' is nice but we never 'put all of our eggs in one basket'."
