The exchange offers and the solicitation of consents are being made under terms and subject to the conditions set forth in the prospectus filed by AMB and AMB LP with the Securities and Exchange Commission (the “SEC”) and a related letter of transmittal and consent that contains a more complete description of the terms and conditions of the exchange offers and the solicitation of consents.

A holder who validly tenders its ProLogis Notes for exchange will be deemed to have delivered its consent to the Proposed Amendments. Tenders of ProLogis Notes may be withdrawn any time prior to 9:00 a.m., New York City time, on June 3, 2011, unless extended by AMB LP (the “Expiration Date”). Consents to the Proposed Amendments delivered prior to the Early Consent Date may not be revoked after the Early Consent Date. Consents to the Proposed Amendments delivered after the Early Consent Date and before the Expiration Date may be revoked any time prior to the Expiration Date. Tenders of ProLogis Notes may not be validly withdrawn after the Expiration Date, unless AMB LP otherwise is required by law to permit withdrawal.

A holder who does not validly tender its ProLogis Notes for exchange, or whose notes are not accepted for exchange, will remain a holder of such ProLogis Notes. If the Proposed Amendments to the ProLogis Indenture are adopted, all such ProLogis Notes will be governed by the ProLogis Indenture as amended by the Proposed Amendments, which will have less restrictive terms and afford reduced protections to the holders of such securities compared to those currently in the ProLogis Indenture.

AMB LP’s obligations to complete the exchange offers and the solicitation of consents are conditioned upon, among other things, completion of the merger of equals, listing of AMB LP’s existing 6.750% Notes due 2011 on the New York Stock Exchange and receipt of valid consents sufficient to effect the Proposed Amendments. The merger and related transactions and listing of AMB LP’s existing 6.750% Notes due 2011 on the New York Stock Exchange are not conditioned upon the commencement or completion of the exchange offers or the solicitation of consents.
