Re: Merger Agreement

Dear Mr. Nekritz,

Reference is made to the Agreement and Plan of Merger, dated as of June 11, 2022 (the “Merger Agreement”), by and among Prologis, Inc., a Maryland corporation (“Prologis”), Prologis, L.P., a Delaware limited partnership (“Prologis OP”), Compton Merger Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of Prologis, Compton Merger Sub OP LLC, a Delaware limited liability company and a wholly owned subsidiary of Prologis OP, Duke Realty Corporation, an Indiana corporation (the “Company”), and Duke Realty Limited Partnership, an Indiana limited partnership. Capitalized terms used and not otherwise defined in this letter agreement (this “Letter Agreement”) shall have the respective meanings given to such terms in the Merger Agreement.

By this Letter Agreement, and in accordance with Section 9.5 of the Merger Agreement, the Parties desire to set forth certain agreements and understandings of the Parties in connection with the Merger Agreement as follows:

1. Treatment of Partnership Performance-Based LTIP Unit Awards. Notwithstanding anything in Section 3.2(f) of the Merger Agreement to the contrary, the Parties hereby agree that each Partnership Performance-Based LTIP Unit Award that is outstanding immediately prior to the Partnership Merger Effective Time shall, to the extent unvested, vest in full and shall, as of the Partnership Merger Effective Time, automatically and without any action on the part of the holder thereof, be canceled in exchange for the right of the holder to receive promptly, and in any event within ten (10) Business Days, after the Partnership Merger Effective Time:

a. with respect to the Partnership LTIP Units subject to such Partnership Performance-Based LTIP Unit Award that are earned based on achievement, or deemed achievement, of the target level of achievement under each Partnership Performance-Based LTIP Unit Award in accordance with the last sentence of Section 3.2(f) of the Merger Agreement (the “Base Partnership Performance-Based LTIP Units”), a number of New OP Units equal to (A) the number of Base Partnership Performance-Based LTIP Units subject to such Partnership Performance-Based LTIP Unit Award, as of immediately prior to the Partnership Merger Effective Time, multiplied by (B) the applicable LTIP Conversion Factor (as defined in the Partnership Agreement), multiplied by (C) the Exchange Ratio, less applicable Taxes and withholdings, and such holder shall be admitted as a limited partner of Parent OP following the Partnership Merger Effective Time in accordance with the terms of the Parent Partnership Agreement; and

b. with respect to the Partnership LTIP Units subject to such Partnership Performance-Based LTIP Unit Award that are not Base Partnership Performance-Based LTIP Units, which consist solely of (i) if such Partnership Performance-Based LTIP Unit Award was granted to such holder in calendar year 2020, any additional Partnership LTIP Units earned by such holder prior to the Partnership Merger Effective Time based on achievement of the applicable performance conditions at a level that is above the target level of achievement (if applicable) and (ii) any additional Partnership LTIP Units earned by such holder in respect of such Partnership Performance-Based LTIP Unit Award based on dividends paid by the Company while such award was outstanding and prior to the Partnership Merger Effective Time, in each case of clauses (i) and (ii), in accordance with the terms of the applicable award agreement (the “Additional Partnership Performance-Based LTIP Units”), an amount in cash equal to the VWAP of Parent Common Stock multiplied by a number of shares of Parent Common Stock equal to the product, rounded down to the nearest whole number of shares, of (A) the number of Additional Partnership Performance-Based LTIP Units subject to such Partnership Performance-Based LTIP Unit Award, as of immediately prior to the Partnership Merger Effective Time, multiplied by (B) the applicable LTIP Conversion Factor, multiplied by (C) the Exchange Ratio, less applicable Taxes and withholdings.

For the avoidance of doubt, nothing in this Letter Agreement shall modify the last sentence of Section 3.2(f) of the Merger Agreement; provided, however, that for purposes of determining the number of Partnership LTIP Units subject to each Partnership Performance-Based LTIP Unit Award granted in calendar year 2020, the actual level of achievement of the “Annualized TSR” and “Absolute TSR” performance conditions shall be determined based on the number of full and partial years from the beginning of the applicable performance period to September 20, 2022.
