We have elected to operate as a Real Estate Investment Trust (REIT) for federal tax purposes and pay regular quarterly distributions to our shareholders. A REIT is a corporation or business trust that combines the capital of many investors to acquire or provide financing for all forms of income-producing real estate. REITs are required to pay 90% of taxable income to shareholders each year. For more information, please visit the National Association of Real Estate Investment Trust's website at www.InvestInREITs.com.

On September 15, 2005, Catellus Development Corporation was merged with and into ProLogis. Catellus added over 36.9 million square feet of industrial properties in key logistics markets to our North American portfolio. In addition, Catellus' land bank and skill as a brownfield developer complemented ProLogis' platform providing us with unparalleled development opportunities in North America over the next several years.

Consideration for the merger was set at 65% stock and 35% cash with Catellus holders being allowed to make an election. Holders that elected cash, or made no election at all, received $33.81 per share. Because the majority of Catellus holders elected stock, consideration for those holders was prorated with each receiving a combination of cash and stock. Holders that made a valid election for stock received 72.5733% of their Catellus holdings in ProLogis shares, at an exchange rate of 0.822 of a share of ProLogis for every 1 share of Catellus owned, and the remaining 27.4267% of their Catellus holdings were paid in cash at $33.81 per share. The transaction was deemed "constructive receipt" by the IRS, meaning shareholder proceeds were taxable in 2005.

If you are currently holding a Catellus stock certificate, you need to contact Computershare (formerly Equiserve), our transfer agent, at the phone number below and request a Letter of Transmittal. You should sign this form and return it along with the certificate(s) you hold to Computershare in the self-addressed envelope they will provide. Upon receipt of your stock certificate, Computershare will send you a check for $33.81 per Catellus share you own, including any shares held in book entry. At this time Catellus shares are no longer earning a dividend, nor are you entitled to interest on the cash consideration due you, so it is in your best interests to surrender your shares.

If you have shares of Catellus but have lost your stock certificate(s), please contact Computershare at the number below. They will explain the steps necessary to prepare a surety bond for the lost certificate(s) and receive your proceeds.

In July of 1998, we changed our name from Security Capital Industrial Trust to ProLogis Trust to more accurately reflect our growing global business and create stronger name recognition among our customers. Then in May of 2001, we changed our name from ProLogis Trust to ProLogis.

On March 31, 1999, Meridian Industrial Trust merged with and into ProLogis. Meridian was an excellent strategic fit with ProLogis. This union substantially increased our presence in the largest logistics markets in North America and created significant operational and cost benefits.
