NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, intending to be legally bound, the parties hereto agree as follows:

ARTICLE I
THE MERGERS

1.1. The Mergers.

(a) The ProLogis Merger. (i) Upon the terms and subject to satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the applicable provisions of Title 8 of the Corporations and Associations Article of the Annotated Code of Maryland, as amended (the “Maryland REIT Law”), and the Delaware Limited Liability Company Act (the “DLLCA”), at the ProLogis Effective Time, Pumpkin LLC shall be merged with and into ProLogis (the “ProLogis Merger”). As a result of the ProLogis Merger, the separate existence of Pumpkin LLC shall cease, and ProLogis shall continue as the surviving entity of the ProLogis Merger as a direct wholly owned Subsidiary of Upper Pumpkin and as an indirect wholly owned Subsidiary of New Pumpkin. The ProLogis Merger will have the effects set forth in the Maryland REIT Law and the DLLCA.

(ii) The parties shall cause the ProLogis Merger to be consummated by filing as soon as practicable on the Closing Date (A) articles of merger for the ProLogis Merger (the “Articles of ProLogis Merger”) with the State Department of Assessments and Taxation of the State of Maryland (the “SDAT”), in such form as required by, and executed in accordance with the relevant provisions of, the Maryland REIT Law, and (B) a certificate of merger for the ProLogis Merger (the “Certificate of ProLogis Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with the relevant provisions of, the DLLCA. The ProLogis Merger shall become effective following the close of business on the Closing Date, with such

-2-

date and time specified in the Articles of ProLogis Merger, or on such other date and time as shall be agreed to by AMB and ProLogis and specified in the Articles of ProLogis Merger (such other date and time not to exceed 30 days after the Articles of ProLogis Merger are accepted for record by the SDAT) and the Certificate of ProLogis Merger (the date and time the ProLogis Merger becomes effective being the “ProLogis Effective Time”).

(iii) ProLogis shall elect to be disregarded as an entity separate from its owner pursuant to Treasury Regulation Section 301.7701-3. Such election shall be effective on the Business Day immediately after the date of the ProLogis Effective Time.

(b) The Topco Merger. (i) Upon the terms and subject to satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the Maryland General Corporation Law (the “MGCL”), at the Topco Effective Time, New Pumpkin shall be merged with and into AMB (the “Topco Merger” and, together with the ProLogis Merger, the “Mergers”). As a result of the Topco Merger, the separate existence of New Pumpkin shall cease, and AMB shall continue as the surviving corporation of the Topco Merger (the “Surviving Corporation”) with its corporate name changed to “ProLogis Inc.” The Topco Merger will have the effects set forth in the MGCL.

(ii) The parties shall cause the Topco Merger to be consummated by filing as soon as practicable on the Closing Date articles of merger for the Topco Merger (the “Articles of Topco Merger” and, together with the Articles of ProLogis Merger and the Certificate of ProLogis Merger, the “Articles of Merger”) with the SDAT, in such form as required by, and executed in accordance with the relevant provisions of, the MGCL. The Topco Merger shall become effective before the open of business on the first Business Day following the date of the ProLogis Effective Time, with such date and time specified in the Articles of Topco Merger, or on such other date and time as shall be agreed to by AMB and ProLogis and specified in the Articles of Topco Merger (such other date and time not to exceed 30 days after the Articles of Topco Merger are accepted for record by the SDAT) (the date and time the Topco Merger becomes effective being the “Topco Effective Time”).

(c) Contribution and Issuance. (i) Immediately after the Topco Effective Time, the Surviving Corporation shall contribute all of the outstanding equity interests of Upper Pumpkin to AMB LP (the “Contribution”) in exchange for the issuance by AMB LP of (A) a number of newly issued AMB Partnership Units equal to the aggregate number of shares of AMB Common Stock issued in the Topco Merger and (B) a number of newly issued preferred units of AMB LP equal to the aggregate number of, and with substantially identical rights and preferences as, shares of AMB New Preferred Stock newly issued pursuant to Section 2.1(b)(i) ((A) and (B) together, the “Issuance”). As a result of the Contribution, Upper Pumpkin shall become a wholly owned subsidiary of AMB LP. Following the Contribution, AMB LP shall change its name to “ProLogis, L.P.”

(ii) The parties shall cause the Contribution and the Issuance to be consummated on the Closing Date immediately after the Topco Effective Time by executing an assignment and assumption agreement or other instrument of transfer or conveyance

-3-

(in each case, in form and substance reasonably acceptable to the parties hereto) to sell, transfer and convey to AMB LP all of the outstanding equity interests in Upper Pumpkin and by issuing to the Surviving Corporation evidence of ownership of the AMB Partnership Units and preferred units of AMB LP issued in the Issuance.

1.2. Closing. The closing of the Mergers, the Contribution and the Issuance (the “Closing”) will take place on the date (the “Closing Date”) that is the second Business Day after the satisfaction or waiver (subject to applicable Law) of the conditions set forth in Article VI (excluding conditions that, by their terms, are to be satisfied on the Closing Date, but subject to the satisfaction or waiver of those conditions as of the Closing), unless another date is agreed to in writing by the parties hereto. The Closing shall be held at the offices of Wachtell, Lipton, Rosen & Katz, 51 West 52^nd Street, New York, NY 10019, unless another place is agreed to in writing by the parties hereto.

1.3. Charter and Bylaws. (a) The charter of AMB as in effect immediately prior to the Topco Effective Time shall be the charter of the Surviving Corporation, except that the name of Surviving Corporation shall be “ProLogis Inc.” and except for such amendments to the charter of AMB that are approved by the AMB stockholders pursuant to Section 1.3(b). The Bylaws of the Surviving Corporation shall be in the form set forth on Exhibit A. The Declaration of Trust of ProLogis as in effect immediately prior to the ProLogis Effective Time shall be the Declaration of Trust of the surviving entity of the ProLogis Merger. The Bylaws of ProLogis as in effect immediately prior to the ProLogis Effective Time shall be the Bylaws of the surviving entity of the ProLogis Merger.

(b) Unless AMB and ProLogis otherwise agree, AMB shall use reasonable best efforts to submit to the vote of its stockholders an amendment to the charter of AMB so that, following such amendment, (i) the board of directors of AMB, with the approval of a majority of the entire board and without action by the AMB stockholders, may amend the charter of AMB to increase or decrease the aggregate number of shares of stock of AMB or the number of shares of stock of any class or series that AMB has authority to issue; (ii) the charter of AMB may be amended by the affirmative vote of the holders of at least a majority of the shares of AMB Common Stock then outstanding and entitled to vote thereon; and (iii) if any AMB stockholder approval is required for any action, such action shall be effective and valid if declared advisable by the board of directors of AMB and taken or approved by a vote of a majority of the shares of AMB Common Stock then outstanding and entitled to vote thereon (the amendments set forth in clauses (i), (ii) and (iii), the “AMB Charter Amendments”). The parties agree that the approval of, and implementation of, any or all of the AMB Charter Amendments shall not be a condition to the parties’ obligation to effect the Mergers or the other transactions contemplated by this Agreement.

1.4. Tax Consequences. It is intended that each of the Mergers shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be, and is adopted as, a separate “plan of reorganization” for each Merger for purposes of Sections 354 and 361 of the Code.

STOCK OF THE CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

2.1. Effect on Membership Interests, Shares of Beneficial Interest or Capital Stock.

(a) Membership Interests of Pumpkin LLC and ProLogis Shares of Beneficial Interest and New Pumpkin Capital Stock. As of the ProLogis Effective Time, by virtue of the ProLogis Merger and without any action on the part of the holder of any shares of beneficial interest of ProLogis, shares of capital stock of New Pumpkin or any membership interests in Pumpkin LLC, the following shall occur:

(i) Membership Interests of Pumpkin LLC. Each membership interest of Pumpkin LLC issued and outstanding immediately prior to the ProLogis Effective Time shall be automatically converted into and become one fully paid and nonassessable common share of beneficial interest, par value $0.01 per share, of the surviving entity of the ProLogis Merger, and such share of beneficial interest of the surviving entity shall be owned by Upper Pumpkin.

(ii) Conversion of ProLogis Common Shares of Beneficial Interest. Each common share of beneficial interest, par value $0.01 per share, of ProLogis (“ProLogis Common Share”) issued and outstanding immediately prior to the ProLogis Effective Time shall be automatically converted into one newly issued share of common stock, par value $0.01 per share, of New Pumpkin (“New Pumpkin Common Stock”). As a result of the ProLogis Merger, all ProLogis Common Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each certificate previously evidencing ProLogis Common Shares shall thereafter represent the shares of New Pumpkin Common Stock into which such ProLogis Common Shares were converted (and, following the Topco Effective Time, shares of AMB Common Stock into which such shares of New Pumpkin Common Stock have been converted pursuant to Section 2.1(b)).

(iii) Exchange of ProLogis Preferred Shares of Beneficial Interest. Pursuant to a share exchange effected by the ProLogis Merger, (A) each ProLogis Series C Preferred Share issued and outstanding immediately prior to the ProLogis Effective Time shall be automatically exchanged for one newly issued share of Series C Cumulative Redeemable Preferred Stock, par value $0.01 per share, of New Pumpkin (“New Pumpkin Series C Preferred Stock”), (B) each ProLogis Series F Preferred Share issued and outstanding immediately prior to the ProLogis Effective Time shall be automatically exchanged for one newly issued share of Series F Cumulative Redeemable Preferred Stock, par value $0.01 per share, of New Pumpkin (“New Pumpkin Series F Preferred Stock”) and (C) each ProLogis Series G Preferred Share issued and outstanding immediately prior to the ProLogis Effective Time shall be automatically exchanged for one newly issued share of Series G Cumulative Redeemable Preferred Stock, par value $0.01 per share, of New Pumpkin (“New Pumpkin Series G Preferred Stock” and, together with the New Pumpkin Series C Preferred Stock and the New Pumpkin Series F Preferred Stock, the

-5-

“New Pumpkin Preferred Stock”). As a result of such share exchange, all ProLogis Preferred Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each certificate previously evidencing ProLogis Preferred Shares shall thereafter represent the shares of New Pumpkin Preferred Stock for which such ProLogis Preferred Shares were exchanged (and, following the Topco Effective Time, shares of AMB Preferred Stock into which such shares of New Pumpkin Preferred Stock have been converted pursuant to Section 2.1(b)).

(iv) Conversion of Rights to Redeem or Exchange ProLogis Partnership Units and Rights to Convert Convertible Debt. Each right of a limited partner in a ProLogis Partnership to redeem or exchange its ProLogis Partnership Units for ProLogis Common Shares (or cash equivalents thereof) pursuant to the partnership agreement of the applicable ProLogis Partnership outstanding immediately prior to the ProLogis Effective Time shall be automatically converted into the right to redeem or exchange such ProLogis Partnership Units for a number of shares of New Pumpkin Common Stock (or cash equivalents thereof) equal to the number of ProLogis Common Shares that such limited partner would have received if the redemption or exchange occurred immediately prior to the ProLogis Effective Time, as such number of shares may be adjusted and on the terms pursuant to the agreements governing such ProLogis Partnership Units. Each right of a holder of ProLogis’s convertible debt to convert such convertible debt into ProLogis Common Shares outstanding immediately prior to the ProLogis Effective Time shall be converted into the right to convert such convertible debt into a number of shares of New Pumpkin Common Stock equal to the number of ProLogis Common Shares that such holder would have received if the conversion occurred immediately prior to the ProLogis Effective Time (as such number of shares may be adjusted and on the terms pursuant to the agreements governing such convertible debt), pursuant to the adoption of a supplemental indenture as contemplated pursuant to Section 5.14.

(b) New Pumpkin Capital Stock. As of the Topco Effective Time, by virtue of the Topco Merger and without any action on the part of any holder of any shares of capital stock of New Pumpkin or AMB, the following shall occur:

(i) Conversion of New Pumpkin Common Stock and New Pumpkin Preferred Stock. Subject to Section 2.2(e), (A) each share of New Pumpkin Common Stock issued and outstanding immediately prior to the Topco Effective Time shall be automatically converted into the right to receive 0.4464 (the “Exchange Ratio”) of a newly issued share of common stock, par value $0.01 per share, of AMB (“AMB Common Stock”), (B) each share of New Pumpkin Series C Preferred Stock issued and outstanding immediately prior to the Topco Effective Time shall be automatically converted into the right to receive one newly issued share of Series Q Cumulative Redeemable Preferred Stock, par value $0.01 per share, of AMB (“AMB Series Q Preferred Stock”), (C) each share of New Pumpkin Series F Preferred Stock issued and outstanding immediately prior to the Topco Effective Time shall be automatically converted into the right to receive one newly issued share of Series R Cumulative Redeemable Preferred Stock, par value $0.01 per share, of AMB (“AMB Series R Preferred Stock”), and (D) each share of New Pumpkin Series G Preferred Stock issued and outstanding immediately prior to the Topco Effective Time shall be automatically converted into the right to receive one newly issued share of

-6-

Series S Cumulative Redeemable Preferred Stock, par value $0.01 per share, of AMB (“AMB Series S Preferred Stock” and, together with the AMB Series Q Preferred Stock and the AMB Series R Preferred Stock, the “AMB New Preferred Stock”). As a result of the Topco Merger, all shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock shall no longer be outstanding and shall be automatically cancelled and retired and shall cease to exist, and each ProLogis Certificate shall thereafter represent the right to receive the shares of AMB Common Stock and AMB New Preferred Stock, as applicable, into which such shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock were converted. ProLogis Certificates shall be exchanged for certificates representing whole shares of AMB Common Stock and shares of AMB New Preferred Stock, as applicable, issued in consideration therefor upon the surrender of such certificates in accordance with Section 2.2, without interest.

(ii) Conversion of Rights to Redeem or Exchange New Pumpkin Partnership Units and Rights to Convert Convertible Debt. Each right of a limited partner in a ProLogis Partnership to redeem or exchange its ProLogis Partnership Units for shares of New Pumpkin Common Stock (or cash equivalents thereof) pursuant to Section 2.1(a)(iv) shall be automatically converted into the right to redeem or exchange such ProLogis Partnership Units for that number of shares of AMB Common Stock (or cash equivalents thereof) equal to the product of the number of shares of New Pumpkin Common Stock that such limited partner would have received if the redemption or exchange occurred immediately prior to the Topco Effective Time multiplied by the Exchange Ratio, as such number of shares may be adjusted and on the terms pursuant to the agreements governing such ProLogis Partnership Units. Each right of a holder of ProLogis’s convertible debt to convert such convertible debt into shares of New Pumpkin Common Stock pursuant to Section 2.1(a)(iv) shall be converted into the right to convert such convertible debt into that number of shares of AMB Common Stock equal to the product of the number of shares of New Pumpkin Common Stock that such holder would have received if the conversion occurred immediately prior to the Topco Effective Time multiplied by the Exchange Ratio (as such number of shares may be adjusted and on the terms pursuant to the agreements governing such convertible debt), pursuant to the adoption of a supplemental indenture as contemplated pursuant to Section 5.14.

(c) AMB Capital Stock. Each share of AMB Common Stock and AMB Preferred Stock shall remain outstanding following the Topco Effective Time as shares of the Surviving Corporation.

2.2. Exchange of Certificates.

(a) Exchange Agent. As of the Topco Effective Time, AMB shall deposit, or shall cause to be deposited, with a bank or trust company designated by AMB and reasonably acceptable to ProLogis (the “Exchange Agent”), for the benefit of the holders of certificates or evidence of shares in book-entry form which immediately prior to the Topco Effective Time represented shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock (including certificates formerly evidencing ProLogis Common Shares and ProLogis Preferred Shares as of immediately prior to the ProLogis Effective Time, and collectively, the “ProLogis Certificates”), for exchange in accordance with this Article II, certificates or, at AMB’s option, evidence of

-7-

shares in book-entry form (collectively “certificates”) representing the shares of AMB Common Stock and AMB New Preferred Stock issuable pursuant to Section 2.1 in exchange for such shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock. Such certificates for shares of AMB Common Stock and AMB New Preferred Stock so deposited, together with any dividends or distributions with respect thereto, are hereinafter referred to as the “Exchange Fund.”

(b) Exchange Procedures. As soon as reasonably practicable after the Topco Effective Time, the Exchange Agent shall mail to each holder of record of shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock immediately prior to the Topco Effective Time whose shares were converted into the right to receive shares of AMB Common Stock and AMB New Preferred Stock pursuant to Section 2.1, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the ProLogis Certificates shall pass, only upon delivery of the ProLogis Certificates to the Exchange Agent, and which shall be in such form and have such other provisions as AMB and ProLogis may reasonably specify) and (ii) instructions for use in effecting the surrender of the ProLogis Certificates in exchange for certificates representing shares of AMB Common Stock and AMB New Preferred Stock. Upon surrender of a ProLogis Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, and such other documents as the Exchange Agent may reasonably require, the holder of such ProLogis Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of AMB Common Stock and AMB New Preferred Stock which such holder has the right to receive in respect of the ProLogis Certificate surrendered pursuant to the provisions of this Article II (after taking into account all shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock then held by such holder), and the ProLogis Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of ProLogis Common Shares or ProLogis Preferred Shares which is not registered in the transfer records of ProLogis or a transfer of ownership of New Pumpkin Common Stock or New Pumpkin Preferred Stock which is not registered in the transfer records of New Pumpkin, a certificate representing the proper number of shares of AMB Common Stock and AMB New Preferred Stock, as applicable, may be issued to a transferee if the ProLogis Certificate representing the applicable New Pumpkin Common Stock or New Pumpkin Preferred Stock is presented to the Exchange Agent, accompanied by all documents reasonably required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.2, each ProLogis Certificate shall be deemed at any time after the Topco Effective Time to represent only the right to receive AMB Common Stock or AMB New Preferred Stock into which the shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock represented by such ProLogis Certificate have been converted as provided in this Article II and the right to receive upon such surrender cash in lieu of any fractional shares of AMB Common Stock as provided in this Section 2.2.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made with respect to AMB Common Stock or AMB New Preferred Stock with a record date after the Topco Effective Time shall be paid to the holder of any unsurrendered ProLogis Certificate with respect to the shares of AMB Common Stock or AMB New Preferred Stock, as the case may be, represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e), until the holder of

-8-

such ProLogis Certificate shall surrender such ProLogis Certificate. Subject to the effect of applicable Laws, following the surrender of any such ProLogis Certificate, there shall be paid to the holder of the certificates representing whole shares of AMB Common Stock or AMB New Preferred Stock issued in exchange therefor, without interest, (i) at the time of such surrender the amount of any cash payable with respect to a fractional share of AMB Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Topco Effective Time theretofore paid (but withheld pursuant to the immediately preceding sentence) with respect to such whole shares of AMB Common Stock or AMB New Preferred Stock, as the case may be, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Topco Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of AMB Common Stock or AMB New Preferred Stock, as the case may be.

(d) No Further Ownership Rights. All shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock issued upon conversion of ProLogis Common Shares and ProLogis Preferred Shares in accordance with the terms hereof, and all shares of AMB Common Stock and AMB New Preferred Stock issued upon conversion of shares of New Pumpkin Common Stock and New Pumpkin Preferred Stock (including any cash paid pursuant to Section 2.2(c) or 2.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such ProLogis Common Shares and ProLogis Preferred Shares and such shares of New Pumpkin Common Stock and New Pumpkin Preferred Shares, respectively; subject, however, to the Surviving Corporation’s obligation to pay any dividends or make any other distributions with a record date prior to the ProLogis Effective Time which may have been declared or made by ProLogis or New Pumpkin on such ProLogis Common Shares or ProLogis Preferred Shares or shares of New Pumpkin Common Stock or New Pumpkin Preferred Stock in accordance with the terms of this Agreement on or prior to the ProLogis Effective Time and which remain unpaid at the ProLogis Effective Time, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the ProLogis Common Shares and ProLogis Preferred Shares which were outstanding immediately prior to the ProLogis Effective Time or of the shares of New Pumpkin Common Stock or New Pumpkin Preferred Stock which were outstanding immediately prior to the Topco Effective Time.

Nothing contained in this Agreement shall be deemed to relieve AMB of its obligation to submit the Topco Merger to its stockholders for a vote on the approval thereof. AMB agrees that, unless this Agreement shall have been terminated in accordance with Section 7.1, its obligations to hold the AMB Stockholders Meeting pursuant to this Section 5.1(b) shall not be affected by the commencement, public proposal, public disclosure or communication to AMB of any Acquisition Proposal or by any Change in AMB Recommendation.

Neither party nor

any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of its customers, jeopardize the attorney-client privilege of the institution in possession or control of such information or contravene any law, rule, regulation, order, judgment, decree or binding agreement entered into prior to the date of this Agreement. The parties will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

AMB or ProLogis, as applicable, shall provide the other with a copy of any nonpublic information or data provided to a third party pursuant to the prior sentence prior to or simultaneously with furnishing such information to such third party.

(ii) Each party shall notify the other party promptly (but in no event later than 24 hours) after receipt of any Acquisition Proposal, or any request for nonpublic in-

(iv) Notwithstanding anything in this Agreement to the contrary, with respect to an Acquisition Proposal, the Board of Directors of AMB or Board of Trustees of ProLogis, as applicable, may make a Change in AMB Recommendation or a Change in ProLogis Recommendation, as applicable, if and only if (A) an unsolicited bona fide written Acquisition Proposal (that did not result from a breach of this Section 5.4) is made to AMB or ProLogis, as applicable, by a third party, and such Acquisition Proposal is not withdrawn, (B) the Board of Directors of AMB or the Board of Trustees of ProLogis, as applicable, has concluded in good faith (after consultation with its outside legal counsel and financial advisors) that such Acquisition Proposal constitutes a Superior Proposal, (C) the directors of AMB or the trustees of ProLogis, as applicable, have concluded in good faith (after consultation with their outside legal counsel) that failure to do so would be inconsistent with their duties under applicable Law, (D) five Business Days shall have elapsed since the party proposing to take such action has given written notice to the other party advising such other party that the notifying party intends to take such action and specifying in reasonable detail the reasons therefor, including the terms and conditions of any such Superior Proposal that is the basis of the proposed action (a “Notice of Recommendation Change”) (it being understood that any amendment to any material term of such Superior Proposal shall require a new Notice of Recommendation Change and a new five-Business-Day period), (E) during such five-Business-Day period, the notifying party has considered and, at the reasonable request of the other party, engaged in good faith discussions with such party regarding, any adjustment or modification of the terms of this Agreement proposed by the other party, and (F) the directors or trustees, as applicable, of the party proposing to take such action, following such five-

-52-

(v) Notwithstanding anything in this Agreement to the contrary, in circumstances not involving or relating to an Acquisition Proposal, the Board of Directors of AMB or Board of Trustees of ProLogis, as applicable, may make a Change in AMB Recommendation or a Change in ProLogis Recommendation, as applicable, if and only if (A) a material development or change in circumstances has occurred or arisen after the date of this Agreement that was neither known to such party nor reasonably foreseeable as of the date of this Agreement (and which change or development does not relate to an Acquisition Proposal), (B) the directors or trustees, as applicable, of the party proposing to take such action have first reasonably determined in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable Law, (C) five Business Days shall have elapsed since the party proposing to take such action has given a Notice of Recommendation Change to the other party advising that the notifying party intends to take such action and specifying in reasonable detail the reasons therefor, (D) during such five-Business-Day period, the notifying party has considered and, at the reasonable request of the other party, engaged in good faith discussions with such party regarding, any adjustment or modification of the terms of this Agreement proposed by the other party, and (E) the directors or trustees, as applicable, of the party proposing to take such action, following such five-Business-Day period, again reasonably determine in good faith (after consultation with outside legal counsel, and taking into account any adjustment or modification of the terms of this Agreement proposed by the other party) that failure to do so would be inconsistent with their duties under applicable Law.

(vi) Nothing contained in this Section 5.4 shall prohibit either party or its Subsidiaries from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its position thereunder; provided, however, that compliance with such rules shall not in any way limit or modify the effect that any action taken pursuant to such rules has under any other provision of this Agreement, including Section 7.1(d) or (e), as applicable, and provided, further that any such disclosure that addresses or relates to the approval, recommendation or declaration of advisability by the Board of Directors or Board of Trustees of such party, as applicable, with respect to this Agreement or an Acquisition Proposal shall be deemed to be a Change in AMB Recommendation or Change in ProLogis Recommendation, as applicable, unless the Board of Directors or Board of Trustees, as applicable, of such party, in connection with such communication publicly states that its recommendation with respect to this Agreement and the transactions contemplated hereby has not changed or refers to the prior recommendation of such party, without disclosing any Change in AMB Recommendation or Change in ProLogis Recommendation, as applicable.

-53-

-62-

the extent reasonably possible the incurrence of income or excise Tax (any dividend paid pursuant to this paragraph, a “REIT Dividend”).

(c) If either party determines that it is necessary to declare a REIT Dividend, it shall notify the other party at least 20 days prior to the date for the AMB Stockholders Meeting, in the case of a declaration by AMB, or the ProLogis Shareholders Meeting, in the case of a declaration by ProLogis, and such other party shall be entitled to declare a dividend per share payable (i) in the case of AMB, to holders of AMB Common Stock, in an amount per share of AMB Common Stock equal to the quotient obtained by dividing (A) the REIT Dividend declared by ProLogis with respect to each ProLogis Common Share by (B) the Exchange Ratio and (ii) in the case of ProLogis, to holders of ProLogis Common Shares, in an amount per ProLogis Common Share equal to the product of (x) the REIT Dividend declared by AMB with respect to each share of AMB Common Stock and (y) the Exchange Ratio. The record date and payment date for any dividend payable pursuant to this Section 5.10(c) shall be the close of business on the last Business Day prior to the Closing Date.

(d) If, and to the extent, the terms of any series of AMB Preferred Stock or ProLogis Preferred Shares require the payment of a dividend or other distribution by reason of a payment of a REIT Dividend or a dividend paid pursuant to Section 5.10(c), AMB or ProLogis, as applicable, shall declare and pay any such required dividends or other distributions.

5.11. Public Announcements. AMB and ProLogis shall use reasonable best efforts (a) to develop a joint communications plan, (b) to ensure that all press releases and other public statements with respect to the transactions contemplated hereby shall be consistent with such joint communications plan, and (c) except in respect of any announcement required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, to consult with each other before issuing any press release or, to the extent practical, otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby.

Each party shall provide the other party with its stockholder or shareholder lists and allow and facilitate the other party’s contact with its stockholders or shareholders and prospective investors and following a Change in AMB Recommendation or Change in ProLogis Recommendation, as the case may be, such contacts may be made without regard to the above limitations of this Section 5.11.

5.12. Additional Agreements. In case at any time after the Topco Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of AMB, ProLogis or New Pumpkin, the proper officers, directors and trustees of each party to this Agreement shall take all such necessary action.

5.13. Tax Matters. AMB, ProLogis and New Pumpkin agree to use their reasonable best efforts to cause each of the ProLogis Merger and the Topco Merger to qualify as a

-63-

To be properly brought before the annual meeting, business must be either (i) specified in the notice of annual meeting (or any supplement or amendment thereto) given by or at the direction of the board of directors, (ii) otherwise brought before the annual meeting by or at the direction of the board of directors, or (iii) otherwise brought before the annual meeting by a stockholder of the Corporation entitled to vote on the matter at the meeting who complies with the notice procedures set forth in this Section 2 of Article II and who was a stockholder of record both at the time of giving of notice provided for in this Section 2 of Article II and at the time of the annual meeting. In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a stockholder, such business must be a proper matter for action by the stockholders and the stockholder must have given timely notice thereof in writing to the secretary of the Corporation. To be timely, a stockholder’s notice must be delivered to or mailed and received at the principal executive offices of the Corporation, not less than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is advanced or delayed by more than thirty (30) days from the first anniversary of the preceding year’s annual meeting, notice by the stockholder to be timely must be so received not more than one hundred twenty (120) days prior to the date of the annual meeting and not less than the later of ninety (90) days prior to the date of the annual meeting or, if less than one hundred (100) days’ notice or prior public disclosure of the date of the annual meeting is given or made to stockholders, the close of business on the tenth (10th) day following the day on which such notice of the date of the annual

meeting was mailed or such public disclosure was made. In no event shall any postponement or adjournment of an annual meeting, or the announcement thereof, commence a new time period for the giving of a stockholder’s notice as described above. A stockholder’s notice to the secretary shall set forth (a) as to each matter the stockholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and record address of the stockholder proposing such business, (iii) the class, series and number of shares of capital stock of the Corporation which are beneficially owned by the stockholder, and (iv) any material interest of the stockholder in such business and any material interest of any Stockholder Associated Person (as defined below) in such business, individually or in the aggregate, including any anticipated benefit to the stockholder or the Stockholder Associated Person therefrom, and (b) as to the stockholder giving the notice and any Stockholder Associated Person (i) the name and record address (and current address, if different) of the stockholder and the Stockholder Associated Person, (ii) the class, series and number of shares of capital stock of the Corporation which are beneficially owned or owned of record by the stockholder and by such Stockholder Associated Person, if any, and the nominee holder for, and the number of, shares owned beneficially but not of record by such stockholder and by any such Stockholder Associated Person, (iii) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any short position or any borrowing or lending of shares of stock) has been made, the effect or intent of which is to mitigate loss to or manage risk of stock price changes for, or to increase the voting power of, such stockholder or any such Stockholder Associated Person with respect to any share of stock of the Corporation, and a general description of whether and the extent to which such stockholder or such Stockholder Associated Person has engaged in such activities with respect to shares of stock or other equity interests of any other company, and (iv) to the extent known by the stockholder giving the notice, the name and address of any other stockholder supporting the proposal of other business on the date of such stockholder’s notice. For purposes of these bylaws, “Stockholder Associated Person” shall mean, with respect to any stockholder, (x) any person controlling, directly or indirectly, or acting in concert with, such stockholder, (y) any beneficial owner of shares of stock of the Corporation owned of record or beneficially by such stockholder, and (z) any person controlling, controlled by or under common control with such Stockholder Associated Person. Notwithstanding anything in these bylaws to the contrary, no business shall be conducted at the annual meeting except in accordance with the procedures set forth in this Section 2 of Article II and no person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in Section 2(a) of Article III. The officer of the Corporation presiding at an annual meeting shall, if the facts warrant, determine that business was not properly brought before the annual meeting in accordance with the provisions of this Section 2 of Article II, and if he should so determine, he shall so declare to the annual meeting and any such business not properly brought before the meeting shall not be transacted.

Section 3. A majority of the stock issued and outstanding and entitled to vote at any meeting of stockholders, the holders of which are present in person or represented by proxy, shall constitute a quorum for the transaction of business except as otherwise provided by law, by the Corporation’s charter or by these bylaws. A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum and the votes present may continue to transact business until adjournment. If, however, such quorum shall not be present or

-2-

represented at any meeting of the stockholders, a majority of the voting stock represented in person or by proxy may adjourn the meeting from time to time until a date not more than 120 days after the original record date, without notice other than announcement at the meeting, until a quorum shall be present or represented. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. If the adjournment is for more than 120 days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote thereat.

Section 4. When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the Maryland General Corporation Law (“MGCL”) or the rules of any securities exchange on which the Corporation’s capital stock is listed or the Corporation’s charter or these bylaws, a different vote is required, in which case such express provision shall govern and control the decision of such question.

Section 5. At each meeting of the stockholders, each stockholder having the right to vote may vote in person or may authorize another person or persons to act for him by proxy in any manner permitted by applicable law. All proxies must be filed with the secretary of the Corporation at the beginning of each meeting in order to be counted in any vote at the meeting. Subject to the provisions of the charter of the Corporation, each stockholder shall have one vote for each share of stock having voting power registered in his name on the books of the Corporation on the record date set by the board of directors as provided in Section 6 of Article V.

Section 6.

a. Subject to clause (d) below of this Section 6 of Article II, a favorable vote of a majority of the aggregate of (x) the votes cast “for” a director nominee and (y) the votes cast “against” a director nominee (or if directors are to be elected upon a favorable vote of a majority of the votes cast but in such circumstances stockholders generally are not offered the opportunity to cast a vote “against” a director nominee but instead are offered the opportunity to “withhold” votes, any votes designated to be “withheld” from voting in respect of a director nominee, which for these limited purposes will be deemed a vote cast and have the affect of a vote “against”), at a meeting of the stockholders duly called and held at which a quorum is present, shall be required to elect such director nominee. For purposes of determining whether a director nominee has received a favorable vote of a majority of the aggregate of the votes cast, a majority of the aggregate votes cast means that the number of shares voted “for” a director must exceed the number of votes cast “against” that director (or, if the director is nevertheless to be elected upon a favorable vote of a majority of the votes cast but stockholders generally are not offered the opportunity to cast a vote “against” the director nominee but instead are offered the opportunity to “withhold” votes, then the number of shares voted “for” a director must exceed the number of votes “withheld” from voting in respect of such director nominee, which for these limited purposes will be deemed a vote cast). A vote will be considered withheld from a director nominee only if a stockholder is provided the opportunity to and does affirmatively withhold authority to vote for such director nominee in any proxy granted by such stockholder, in any event in accordance with instructions contained in the proxy statement or accompanying proxy

-3-

card circulated for the meeting of stockholders at which the election of directors is to be held or in a ballot to be submitted by such stockholder in person at such meeting. A “broker non-vote” or abstention (or similar expression) shall not in any event be deemed a vote cast for these purposes.

b. If an otherwise incumbent director is not re-elected but would nevertheless for any reason otherwise remain in office, the director shall tender his or her resignation to the Board, subject to subsequent acceptance. The Nominating & Governance Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. The Board will act on the Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results. The director who tenders his or her resignation will not participate in the Board’s decision.

c. Directors properly elected shall hold office until the next annual meeting of stockholders and until their successors shall be duly elected and qualified. Directors need not be stockholders. If, for any cause, the Board of Directors shall not have been elected at an annual meeting, they may be elected as soon thereafter as convenient at a special meeting of the stockholders called for that purpose in the manner provided in these bylaws.

d. The foregoing to the contrary notwithstanding, in the event that the number of director nominees is expected to exceed the number of directors to be elected at a meeting (a “Contested Election”), with the determination that the number of director nominees is expected to exceed the number of directors to be elected, and, therefore, that an election of directors is a Contested Election, being made by the secretary of the Corporation as of the close of the applicable stockholder notice of nomination period set forth in Section 8 of Article II or Section 2(a) of Article III based on whether one or more stockholder notices of nomination were timely filed in accordance with Section 8 of Article II or Section 2(a) of Article III, as applicable (provided that the secretary shall also be able to consider such other facts and circumstances as may be reasonably relevant to the determination that an election of directors is a Contested Election, and provided further that any determination that an election of directors is a Contested Election shall be determinative only as to the timeliness of a stockholder notice of nomination and not otherwise as to its validity), then a plurality of all the votes cast at such meeting shall be sufficient to elect a director, and therefore, and for the avoidance of doubt, the director nominees shall not be elected at such meeting by a favorable vote of a majority of the votes cast. In such case where an election of directors is determined to be a Contested Election, stockholders shall be permitted to vote only “for” or to designate their votes to be “withheld” in respect of a director nominee, and shall not in such circumstance be permitted to vote “against” a nominee; and under such circumstances a vote designated to be “withheld”, although present for purposes of establishing the presence of a quorum, will not be deemed a vote cast or a vote “against”. If, prior to thirty days prior to the time the Corporation mails its initial proxy statement in connection with the election of directors at a meeting, one or more stockholder notices of nomination are withdrawn such that the number of nominees for election as director no longer exceeds the number of directors to be elected, then the election shall not be considered a Contested Election, but in all other cases, once an election is determined to be a Contested Election, a plurality of all the votes cast at such meeting shall be sufficient to elect a director.

-4-

Section 7. Special meetings of the stockholders, for any purpose or purposes, unless otherwise proscribed by the charter, may be called at any time by the chief executive officer, a co-chief executive officer, the president, the chairman of the board, or by a majority of the directors, or by a committee of the board of directors which has been duly designated by the board of directors and whose powers and authority, as provided in a resolution of the board of directors or these bylaws, include the power to call such meetings. In addition, a special meeting of the stockholders of the Corporation shall be called by the secretary of the Corporation on the written request of stockholders entitled to cast at least fifty percent (50%) of all votes entitled to be cast at the meeting, except that, in the case of a special meeting called to consider any matter which is substantially the same as a matter voted on at any special meeting for the stockholders held during the preceding twelve (12) months, the secretary of the Corporation shall not be required to call any such special meeting unless requested by stockholders entitled to cast a majority of all of the votes entitled to be cast at the meeting.

Section 8. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice. Where the Corporation’s notice of meeting specifies that directors are to be elected at such special meeting, nominations of persons for election to the board of directors may be made only (i) pursuant to the Corporation’s notice of meeting, (ii) by or at the direction of the board of directors, (iii) by any committee of persons appointed by the board of directors with authority therefor or (iv) by a stockholder as provided in this Section 8 of Article II. In the event a special meeting of stockholders is called for the purpose of electing one or more directors to the board of directors, any stockholder of the Corporation entitled to vote at the meeting who complies with the notice procedures set forth in this Section 8 of Article II and who was a stockholder of record both at the time of giving of notice provided for in this Section 8 of Article II and at the time of the special meeting, may nominate a person or persons, as the case may be, for election as a director as specified in the Corporation’s notice of meeting if the stockholder’s notice containing the information required by Section 2(a) of Article III shall have been delivered to or mailed and received at the principal executive offices of the Corporation not more than 120 days prior to the date of the special meeting and not less than the later of 90 days prior to the date of the special meeting or, if less than 100 days notice or prior public disclosure of the date of the meeting and of the nominees proposed by the board of directors to be elected at such meeting is given or made to stockholders, the close of business on the tenth (10th) day following the day on which such notice was mailed or such public disclosure was made. In no event shall any postponement or adjournment of a special meeting, or the announcement thereof, commence a new time period for the giving of a stockholder’s notice as described above.

Section 9. Whenever stockholders are required or permitted to take any action at a meeting, a written notice of the meeting shall be given which notice shall state the place, date and hour of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. The written notice of any meeting shall be given to each stockholder entitled to vote at such meeting not less than 10 nor more than 90 days before the date of the meeting. If mailed, notice is given when deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the records of the Corporation.

Section 10. Notwithstanding any other provision of the charter of the Corporation or these bylaws, Subtitle 7 of Title 3 of the MGCL (as the same may hereafter be amended from time to time) shall not apply to the voting rights of any shares of stock of the Corporation now or

-5-

hereafter held by any existing or future stockholder of the Corporation (regardless of the identity of such stockholder).

ARTICLE III

DIRECTORS

Section 1. The board of directors shall consist of a minimum of five (5) and a maximum of thirteen (13) directors. The number of directors shall be fixed or changed from time to time, within the minimum and maximum, by the then elected directors, provided that at least a majority of the directors shall be Independent Directors, as defined from time to time by the Listing Standards of the New York Stock Exchange and any other relevant laws, rules and regulations. Any determination by the board of directors as to the qualification of any director as an “Independent Director” shall be conclusive for all purposes. Until increased or decreased by the directors pursuant to these bylaws, the exact number of directors shall be eleven (11). The directors need not be stockholders. Except as provided in Section 2 of this Article III and in Article VIII with respect to vacancies, the directors shall be elected as provided in the charter at each annual meeting of the stockholders, and each director elected shall hold office until his successor is elected and qualified or until his death, retirement, resignation or removal.

Section 2. (a) Nominations of persons for election to the board of directors of the Corporation at the annual meeting of stockholders may be made only (i) pursuant to the Corporation’s notice of meeting; (ii) by or at the direction of the board of directors or (iii) by any committee of persons appointed by the board of directors with authority therefor or by any stockholder of the Corporation entitled to vote for the election of directors at the meeting who complies with the notice procedures set forth in this Section 2(a) of Article III and who was a stockholder of record both at the time of giving of notice provided for in this Section 2(a) of Article III and at the time of the annual meeting. Such nominations by any stockholder shall be made pursuant to timely notice in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice shall be delivered to or mailed and received at the principal executive offices of the Corporation not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the preceding year’s annual meeting, notice by the stockholder to be timely must be so received not more than 120 days prior to the date of the annual meeting and not less than the later of 90 days prior to the date of the annual meeting or, if less than 100 days notice or prior public disclosure of the date of the meeting is given or made to stockholders, the close of business on the tenth (10th) day following the day on which such notice of the date of the meeting was mailed or such public disclosure was made. In no event shall any postponement or adjournment of an annual meeting, or the announcement thereof, commence a new time period for the giving of a stockholder’s notice as described above. Such stockholder’s notice to the Secretary shall set forth (i) as to each person whom the stockholder proposes to nominate for election or re-election as a director, (a) the name, age, business address and residence address of the person, (b) the principal occupation or employment of the person, (c) the class, series and number of shares of capital stock of the Corporation which are beneficially owned or owned of record by the person, the date such shares were acquired and the investment intent of such acquisition, (d) any other information relating to the person that is required to be disclosed in

-6-

solicitations for proxies for election of directors pursuant to the Rules and Regulations of the Securities and Exchange Commission under Section 14 of the Securities Exchange Act of 1934, as amended, (e) such person’s written consent to serve as a director if elected, and (f) a statement whether such person, if elected or re-elected, or as a condition thereto, will tender an irrevocable resignation effective upon such person’s failure to receive the required vote for re-election at the next meeting at which such person would face re-election and upon acceptance of such resignation by the Board, in accordance with the Corporation’s Corporate Governance Principles (and assuming that such person would otherwise remain in office as a director notwithstanding such failure); and (ii) as to the stockholder giving the notice and any Stockholder Associated Person (a) the name and record address (and current address, if different) of the stockholder and the Stockholder Associated Person, (b) the class, series and number of shares of capital stock of the Corporation which are beneficially owned or owned of record by the stockholder and by such Stockholder Associated Person, if any, and the nominee holder for, and the number of, shares owned beneficially but not of record by such stockholder and by any such Stockholder Associated Person, (c) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any short position or any borrowing or lending of shares of stock) has been made, the effect or intent of which is to mitigate loss to or manage risk of stock price changes for, or to increase the voting power of, such stockholder or any such Stockholder Associated Person with respect to any share of stock of the Corporation, and a general description of whether and the extent to which such stockholder or such Stockholder Associated Person has engaged in such activities with respect to shares of stock or other equity interests of any other company, and (d) to the extent known by the stockholder giving the notice, the name and address of any other stockholder supporting the nominee for election or re-election as a director on the date of such stockholder’s notice. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as a director of the Corporation or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee. Except as may otherwise be provided in these bylaws or any other agreement relating to the right to designate nominees for election to the board of directors, no person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in this Section 2(a) of Article III. The officer of the Corporation presiding at an annual meeting shall, if the facts warrant, determine that a nomination was not made in accordance with the foregoing procedure, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded.

(b) Except as may otherwise be provided pursuant to Article IV of the Corporation’s charter with respect to any rights of holders of preferred stock to elect additional directors and any other requirement in these bylaws or other agreement relating to the right to designate nominees for election to the board of directors, should a vacancy in the board of directors occur or be created (whether arising through death, retirement or resignation), such vacancy shall be filled by the affirmative vote of a majority of the remaining directors, even though less than a quorum of the board of directors or, in the case of a vacancy resulting from an increase in the number of directors, by a majority of the entire board of directors. In the case of a vacancy created by the removal of a director, the vacancy shall be filled by the stockholders of the Corporation entitled to elect the director who was removed at the next annual meeting of stockholders or at a special meeting of stockholders called for such purpose, provided, however,

-7-

that such vacancy may be filled by the affirmative vote of a majority of the remaining directors, subject to approval by the stockholders entitled to elect the director who was removed at the next annual meeting of stockholders or at a special meeting of stockholders called for such purpose. A director so elected to fill a vacancy shall serve for the remainder of the term.

Section 3. The property and business of the Corporation shall be managed by or under the direction of its board of directors. In addition to the powers and authorities by these bylaws expressly conferred upon it, the board may exercise all such powers of the Corporation and do all such lawful acts and things as are not by statute or by the Corporation’s charter or by these bylaws directed or required to be exercised or done by the stockholders.

Section 4. Subject to Article VIII, the board of directors shall elect a chairman of the board of directors who shall hold that position until a successor is elected and qualified. The chairman of the board of directors shall preside at meetings of the stockholders and shall set the agenda for meetings of the board of directors.

Section 5. Regardless of whether the chairman of the board of directors is an Independent Director, the Independent Directors of the board of directors may elect an Independent Director to be the Lead Independent Director. The Lead Independent Director may conduct separate meetings of the Independent Directors and perform other duties appropriate to his or her responsibilities, including: (a) preparing, in consultation with the chairman of the board of directors, committee chairs, and other directors, the agendas for meetings of the board of directors; (b) coordinating the activities of the other Independent Directors; (c) approving, in consultation with other Independent Directors, the retention and compensation of consultants who report directly to the board of directors; (d) reviewing with the chief executive officer (or each co-chief executive officer) such chief executive officer’s performance evaluation conducted by the Independent Directors; (e) presiding at non-management meetings of the Independent Directors and conveying to management directors the results of deliberations among non-management directors; and (f) acting as representative of the non-management for communication with interested parties.

-8-

and on like notice on the written request of the sole director.

Section 7. Unless otherwise restricted by the Corporation’s charter or these bylaws, any action required or permitted to be taken at any meeting of the board of directors or of any committee thereof may be taken without a meeting, if all members of the board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the board or committee.

Section 8. Unless otherwise restricted by the Corporation’s charter or these bylaws, members of the board of directors, or any committee designated by the board of directors, may participate in a meeting of the board of directors, or any committee, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at such meeting.

Section 9. By virtue of resolutions adopted by the Board of Directors prior to or at the time of adoption of these Bylaws and designated irrevocable, any business combination (as defined in Section 3-601(e) of the MGCL) between the Corporation and any of its present or future stockholders, or any affiliates or associates of the Corporation or any present or future stockholder of the Corporation, or any other person or entity or group of persons or entities, is exempt from the provisions of Subtitle 6 of Title 3 of the MGCL entitled “Special Voting Requirements,” including, but not limited to, the provisions of Section 3-602 of such Subtitle. The Board of Directors may not revoke, alter or amend such resolution, or otherwise elect to have any business combination of the Corporation be subject to the provisions of Subtitle 6 of Title 3 of the MGCL without the approval of the holders of the issued and outstanding shares of Common Stock of the Corporation by the affirmative vote of a majority of all votes entitled to be cast in respect of such shares of Common Stock.

Notwithstanding any other provision of these bylaws, all actions which the board of directors may take to approve a transaction between (i) the Corporation, ProLogis Property, L.P., a Delaware limited partnership (the “Operating Partnership”), or any subsidiary of the Corporation or the Operating Partnership, on the one hand, and (ii) (a) any executive officer or director of the Corporation, the Operating Partnership or any subsidiary of the Corporation or the Operating Partnership, or (b) any limited partner of the Operating Partnership or (c) any affiliate of the foregoing executive officer, director or limited partner (not including the Corporation, the Operating Partnership or any subsidiary of the Corporation or the Operating Partnership), on the other hand, shall require, for valid approval, the approval of a majority of the Independent Directors; provided, however, that this approval requirement shall not apply to arrangements between the Corporation or the Operating Partnership and any executive officer or director acting in the executive officer’s or director’s position as such, including but not limited to employment agreements and compensation matters.

RESIGNATION FROM THE BOARD OF DIRECTORS

Section 11. A director may resign at any time upon written notice to the Corporation’s board of directors, chairman of the board of directors, chief executive officer, co-chief executive officer, president or secretary. Any such resignation shall take effect at the time or upon the

-9-

satisfaction of any condition specified therein or, if no time or condition is specified, upon receipt thereof, and the acceptance of such resignation, unless required by the terms thereof (including for example any resignation contemplated by Section 6(b) of Article II), shall not be necessary to make such resignation effective.

COMMITTEES OF DIRECTORS

Section 12. The board of directors may, by resolution passed by a majority of the whole board, designate one or more committees, each such committee to consist of not less than the minimum number of directors required for committees of the board of directors under the MGCL. The board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Any such committee, to the extent provided in the resolution of the board of directors, and to the maximum extent permitted under the MGCL, shall have and may exercise all the powers and authority of the board of directors in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to amending the charter, adopting an agreement of merger or consolidation, recommending to the stockholders the sale, lease or exchange of all or substantially all of the Corporation’s property and assets, recommending to the stockholders a dissolution of the Corporation or a revocation of a dissolution or any other matter requiring the approval of the stockholders of the Corporation, or amending the bylaws of the Corporation; and no such committee shall have the power or authority to authorize or declare a dividend, to authorize the issuance of stock (except that, if the board of directors has given general authorization for the issuance of stock providing for or establishing a method or procedure for determining the maximum number or the maximum aggregate offering price of shares to be issued, or both, a committee of the board of directors may, in accordance with that general authorization or any stock option or other plan or program adopted by the board of directors: authorize or fix the terms of stock subject to classification or reclassification, including the designations and any of the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or terms or conditions of redemption of such shares; within the limits established by the board of directors, fix the number of any such class or series of stock or authorize the increase or decrease in the number of shares of any series or class; and otherwise establish the terms on which any stock may be issued, including the price and consideration for such stock), or to approve any merger or share exchange, regardless of whether the merger or share exchange requires stockholder approval.

Section 13. The Corporation shall from and after the incorporation have the following committees, the specific authority and members of which shall be as designated herein, in such committee’s charter or otherwise by resolution of the board of directors:

(ii) An Audit Committee, which shall consist solely of Independent Directors and which shall engage the independent public accountants, review with the independent public accountants the plans and results of the audit engagement, approve professional services provided by the

-10-

(iii) A Compensation Committee, which shall consist solely of Independent Directors and which shall determine compensation for the Corporation’s executive officers, and will review and make recommendations concerning proposals by management with respect to compensation, bonus, employment agreements and other benefits and policies respecting such matters for the executive officers of the Corporation.

Section 14. Each committee shall keep regular minutes of its meetings and report the same to the board of directors when required. The presence of a majority of the total membership of any committee shall constitute a quorum for the transaction of business at any meeting of such committee and the act of a majority of those present shall be necessary and sufficient for the taking of any action thereat.

COMPENSATION OF DIRECTORS

Section 15. Unless otherwise restricted by the charter of the Corporation or these bylaws, the board of directors shall have the authority to fix the compensation of non-employee directors. The non-employee directors may be paid their expenses, if any, of attendance at each meeting of the board of directors and may be paid a fixed sum for attendance at each meeting of the board of directors or a stated salary as director. Officers of the Corporation who are also members of the board of directors shall not be paid any director’s fees.
