On February 10, 2015, Prologis entered into a contribution agreement to acquire a portfolio of properties for an aggregate gross purchase price of approximately $820 million, including the assumption of debt. Pursuant to the contribution agreement (the “Contribution Agreement”), among Prologis, Inc. (the “Company”), Prologis, L.P. (the “Operating Partnership”), and Morris Realty Associates LLC and the other contributors a party thereto (the “Contributors”), the Company and certain of its subsidiaries agreed to acquire (the “Transaction”) from the Contributors all of the membership interests or partnership interests in certain limited liability companies and partnerships that own industrial and retail properties (the “Properties”) in exchange for a combination of (i) common limited partnership units in the Operating Partnership (“OP Units”) and (ii) a new class of common limited partnership units in the Operating Partnership to be designated as Class A Convertible Common Units (“Class A Units”). The Contribution Agreement contains certain customary representations, warranties, covenants, indemnities and termination rights for a transaction of this nature. The Transaction is subject to the Company’s satisfactory completion of due diligence within 45 days as well as customary closing conditions, including lender consents, and is expected to be completed April 30, 2015 (the “Closing”).

On the Closing of the Transaction, the Operating Partnership expects to issue a combination of OP Units and Class A Units, equal to approximately $400 million (which is subject to adjustment) divided by the “Unit Price”, as consideration for the Transaction. The “Unit Price” for each OP Unit and Class A Unit is expected to be $43.11; provided, that in the event that the closing date for any Property or Properties is postponed by more than sixty days after the originally-scheduled closing under the Contribution Agreement, the price for each OP Unit and Class A Unit will be equal to the average closing price of a share of the Company’s common stock, $0.01 par value per share (the “Common Stock”), on the New York Stock Exchange over a twenty trading day period ending on the trading day before such postponed closing, but not less than consensus NAV per share nor more than 107% of consensus NAV per share as of such date.

The issuance of OP Units and Class A Units is expected to be undertaken in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended, afforded by Section 4(a)(2) thereof. The issuance of OP Units and Class A Units is expected not to involve a public offering and to be made without general solicitation or advertising. Each holder of OP Units and Class A Units is expected to represent that, among other things, it is an accredited investor, as such term is defined in Regulation D.

The Operating Partnership expects to enter into a Second Amendment (the “LPA Amendment”) to the Thirteenth Amended and Restated Agreement of Limited Partnership of the Operating Partnership for the purpose of establishing the terms of Class A Units to be issued in the Transaction. Class A Units are expected to be convertible at any time into OP Units using a conversion factor to be further described in the LPA Amendment. In addition, OP Units are exchangeable on a one-for-one basis for Common Stock one year after their issuance.
