Item 5.04. Temporary Suspension of Trading Under Registrant’s Employee Benefit Plans.

The administrator of the ProLogis 401(k) Savings Plan and Trust (the “Plan”) has determined to implement certain restrictions on the shares of beneficial interest of ProLogis (“ProLogis Shares”) held by the Plan that will be imposed in connection with the anticipated merger (the “Merger”) contemplated by the Agreement and Plan of Merger dated as of January 30, 2011 by and among, ProLogis, New Pumpkin Inc., Upper Pumpkin LLC, Pumpkin LLC, AMB Property Corporation (“AMB”), and AMB Property, L.P., as amended (the “Merger Agreement”). With respect to the foregoing, the administrator of the Plan had sent a notice to the Plan participants informing them that all transactions involving ProLogis Shares in the Plan would be subject to a blackout period which was expected to begin effective at 4:00 p.m. Eastern time on May 31, 2011 and end the week of June 5, 2011.

On May 25, 2011, the administrator of the Plan sent a revised notice to the participants in the Plan informing them that the estimated length of the blackout period has changed and it is now expected to begin effective at 1:00 p.m. Eastern time on May 31, 2011. No change is expected with respect to the ending of the blackout period. It is still expected to end the week of June 5, 2011.

In connection with the foregoing, ProLogis sent a revised notice to its trustees and executive officers in accordance with Section 3.06 of the Sarbanes-Oxly Act of 2002 and Rule 104 of the Securities and Exchange Commission Regulation BTR (Blackout Trading Restriction). A copy of the notice is attached to this Current Report on Form 8-K and is incorporated herein by reference.
