The Company also proposes to issue and sell to the Underwriters not more than an additional $60,000,000 aggregate principal amount of the Company’s 3.25% Convertible Senior Notes due 2015 (the “Additional Securities”) if and to the extent that the Underwriters shall have determined to exercise the right to purchase such 3.25% Convertible Senior Notes due 2015 granted to the Underwriters in Section 2(a) hereof. The Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities”. The Securities will be convertible into common shares of beneficial interest (the “Underlying Securities”) of the Company, par value $0.01 per share (the “Common Stock”). Citigroup Global Markets Inc., Barclays Capital Inc., Deutsche Bank Securities Inc., X.X. Xxxxxx Securities Inc. and Xxxxxx Xxxxxxx & Co. Incorporated have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Securities.

The Securities will be issued pursuant to an indenture, dated as of March 1, 1995 (the “Base Indenture”), between the Company (formerly Security Capital Industrial Trust) and U.S. Bank National Association (as successor in interest to State Street Bank and Trust Company), as trustee (the “Trustee”), as supplemented by the first supplemental indenture, dated as of February 9, 2005 (the “First Supplemental Indenture”), the second supplemental indenture, dated as of November 2, 2005 (the “Second Supplemental Indenture”), the third supplemental indenture, dated as of November 2, 2005 (the “Third Supplemental Indenture”), the fourth supplemental indenture, dated as of March 26, 2007 (the “Fourth Supplemental Indenture”), the fifth supplemental indenture, dated as of November 8, 2007 (the “Fifth Supplemental Indenture”), the sixth supplemental indenture, dated as of May 7, 2008 (the “Sixth Supplemental Indenture”), the seventh supplemental indenture, dated as of May 7, 2008 (the “Seventh Supplemental Indenture”), the eighth supplemental indenture, dated as of August 14, 2009 (the “Eighth Supplemental Indenture”) and the ninth supplemental indenture, dated as of October 2, 2009 (the “Ninth Supplemental Indenture”). Certain terms of the Securities will be established pursuant to

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-157818), which contains a base prospectus dated October 27, 2009 (the “Base Prospectus”), to be used in connection with the public offering and sale of debt securities, including the Securities, and other securities of the Company under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), and the offering thereof from time to time in accordance with Rule 415 under the Securities Act. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act, is called the “Registration Statement.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) after the date and time that this Agreement is executed and delivered by the parties hereto. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed with the Commission pursuant to Rule 424(b). Any reference herein to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents that are or are deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act prior to 4:45 p.m. Eastern Daylight Time on March 9, 2010 (the “Initial Sale Time”). All references in this Agreement to the Registration Statement, the Preliminary Prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”).

The rights, duties, authority and responsibilities of the Collateral Agent and the relationship among the Credit Parties (which includes, without limitation, the holders of debt securities issued under the Indenture, including the Securities) regarding their pari passu interests in the Collateral are governed by the Amended and Restated Security Agency Agreement dated as of October 6, 2005 (as amended and supplemented from time to time, the “Security Agency Agreement”) among the Company, the Collateral Agent, Bank of America, N.A., as Global Administrative Agent under the Global Senior Credit Agreement (in such capacity, the “Global Administrative Agent”) and certain other parties.

The Company and its subsidiaries own or possess sufficient trademarks, trade names, patent rights, copyrights, domain names, licenses, approvals, trade secrets and other similar rights (collectively, “Intellectual Property Rights”) reasonably necessary to conduct their businesses as now conducted, except as would not result in a Material Adverse Change; and the expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has received any notice of infringement or conflict with asserted Intellectual Property Rights of others, which infringement or conflict, if the subject of an unfavorable decision, would result in a Material Adverse Change.

The real property, improvements, equipment and personal property held under lease by the Company or any subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary.

(dd) Tax Law Compliance. The Company and its subsidiaries have filed all material federal, state and foreign income and franchise tax returns or have properly requested extensions thereof and have paid all taxes required to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them except as may be being contested in good faith and by appropriate proceedings. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section 1(r) above in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of the Company or any of its subsidiaries has not been finally determined. With respect to all tax periods in respect of which the Internal Revenue Service is or will be entitled to any claim, the Company has met the requirements for qualification as a real estate investment trust under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Internal Revenue Code”) and the Company’s present and contemplated organizational ownership, method of operation, assets and income are such that the Company will continue to meet such requirements.

(ee) Company Not an “Investment Company.” The Company is not, and after receipt of payment for the Securities and the application of the proceeds as described in the Disclosure Package and the Prospectus under “Use of Proceeds” will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended (the “Investment Company Act”).

(ff) Insurance. Each of the Company and its subsidiaries taken as a whole carry or are covered by insurance in such amounts covering such risks as are generally deemed adequate and customary for their businesses. The Company has no reason to believe that it or any subsidiary will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Change.

(gg) No Price Stabilization or Manipulation. The Company has not taken and will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(hh) No Unlawful Contributions or Other Payments. Neither the Company nor any of its Significant Subsidiaries nor, to the best of the Company’s knowledge, any employee or agent of the Company or any Significant Subsidiary, has made any contribution or other payment to any official of, or candidate for, any federal, state or foreign office in violation of any law or of the character necessary to be disclosed in the Disclosure Package and the Prospectus in order to make the statements therein, in the light of the circumstances under which such statements were made, not misleading.

(ii) Compliance with Environmental Laws. Except as would not, individually or in the aggregate, result in a Material Adverse Change (i) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign law or regulation relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including without limitation, laws and regulations relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum and petroleum products (collectively, “Materials of Environmental Concern”), or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Materials of Environmental Concern (collectively, “Environmental Laws”), which violation includes, but is not limited to, noncompliance with any permits or other governmental authorizations required for the operation of the business of the Company or its subsidiaries under applicable Environmental Laws, or noncompliance with the terms and conditions thereof, nor has the Company or any of its subsidiaries received any written communication, whether from a governmental authority, citizens group, employee or otherwise, that alleges that the Company or any of its subsidiaries is in violation of any Environmental Law; (ii) there is no claim, action or cause of action filed with a court or governmental authority with respect to which the Company has received written notice, no investigation with respect to which the Company has received written notice, and no written notice by any person or entity alleging potential liability for investigatory costs, cleanup costs, governmental responses costs, natural resources damages, property damages, personal injuries, attorneys’ fees or penalties arising out of, based on or resulting from the presence, or release into the environment, of any Material of Environmental Concern at any location owned, leased or operated by the Company or any of its subsidiaries, now or in the past (collectively, “Environmental Claims”), pending or, to the best of the Company’s knowledge, threatened against the Company or any of its subsidiaries or any person or entity whose liability for any Environmental Claim the Company or any of its

subsidiaries has retained or assumed either contractually or by operation of law; and (iii) to the best of the Company’s knowledge, there are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release, emission, discharge, presence or disposal of any Material of Environmental Concern, that reasonably could result in a violation of any Environmental Law or form the basis of a potential Environmental Claim against the Company or any of its subsidiaries or against any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law.

(jj) ERISA Compliance. The Company and its subsidiaries and any “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code, of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan,” (ii) Sections 412, 4971 or 4975 of the Internal Revenue Code, or (iii) Section 4980B of the Internal Revenue Code with respect to the excise tax imposed thereunder. Each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Internal Revenue Code has received a favorable determination letter from the Internal Revenue Service and nothing has occurred, whether by action or failure to act, which is reasonably likely to cause disqualification of any such employee benefit plan under Section 401(a) of the Internal Revenue Code.

(kk) Company’s Accounting System. The Company and its subsidiaries maintain effective internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act.

(ll) Disclosure Controls and Procedures. The Company has established and maintains disclosure controls and procedures (as such term is defined in Rules 13a-15 and 15d-14 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company and its subsidiaries is made known to the chief executive officer and chief financial officer of the Company by others within the Company or any of its subsidiaries, and such disclosure controls and procedures are reasonably effective to perform the functions for which they were established subject to the limitations of any such control system; the Company’s auditors and the audit committee of the board of directors of the Company have been advised of: (i) any significant deficiencies or material weaknesses in the design or operation of internal controls which could adversely affect the Company’s ability to

record, process, summarize, and report financial data; and (ii) any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

Any certificate signed by any officer of the Company or any of its subsidiaries and delivered to the Underwriters or to counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company to each Underwriter as to the matters set forth therein on the date of such certificate and, unless subsequently amended or supplemented, at each Representation Date subsequent thereto.

The Company acknowledges that the Underwriters and, for purposes of the opinions to be delivered pursuant to Section 5 hereof, counsel for the Company and counsel for the Underwriters, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

Section 2. Purchase, Sale and Delivery of the Securities.

(a) The Securities. The Company agrees to issue and sell to the several Underwriters, severally and not jointly, all of the Firm Securities upon the terms herein set forth. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Underwriters agree, severally and not jointly, to purchase from the Company the aggregate principal amount of Firm Securities set forth opposite their names on Schedule A at a purchase price of 98.000% of the principal amount of the 3.25% Convertible Senior Notes due 2015 (the “Purchase Price”), payable on the Closing Date (as defined below).

On the basis of the representations, warranties and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to issue and sell to the several Underwriters, severally and not jointly, the Additional Securities, and the Underwriters shall have the right to purchase in whole, or from time to time in part, up to $60,000,000 aggregate principal amount of Additional Securities at the Purchase Price plus accrued interest, if any, from the Closing Date (as defined in Section 2(b) hereof) to the date of payment and delivery. The Representatives may exercise this right in whole or from time to time in part by giving written notice of each election to exercise this option not later than 30 days after the Closing Date. Any exercise notice shall specify the number of Additional Securities to be purchased by the Underwriters and the date on which such Additional Securities are to be purchased. Each purchase date must be at least one business day after the written notice is given and may not be earlier than the Closing Date nor later than ten business days after the date of such notice. Additional Securities may be purchased as provided in this Section 2 solely for the purpose of covering over-allotments made in connection with the offering of the Firm Securities. On the Optional Closing Date (as defined below) if any, each Underwriter agrees, severally and not jointly, to purchase the number of Additional Securities that bears the same proportion to the total number of Firm Securities to be purchased on such Optional Closing Date as the number of

Firm Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Additional Securities.

(b) The Closing Date and Optional Closing Date(s). Delivery of certificates for the Firm Securities in global form to be purchased by the Underwriters and payment therefor shall be made at the offices of Shearman & Sterling LLP (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m., New York City time, on March 16, 2010, or such other time and date as the Underwriters shall designate by notice to the Company (the time and date of such closing are called the “Closing Date”).

Payment for and delivery of certificates for the Additional Securities will be made at the offices of Shearman & Sterling LLP (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m., New York City time, on the Closing Date or at such other time or place on the same or such other date, not later than April 15, 2010, as the Representatives and the Company may agree upon in writing (the time and date of such payment and delivery is referred to herein as the “Optional Closing Date”).

(c) Public Offering of the Securities. The Representatives hereby advise the Company that the Underwriters intend to offer for sale to the public, as described in the Disclosure Package and the Prospectus, their respective portions of the Securities, as soon after this Agreement has been executed as the Representatives, in their sole judgment, have determined is advisable and practicable.

(d) Payment for the Securities. Payment for the Securities shall be made at the Closing Date by wire transfer of immediately available funds to the order of the Company.

It is understood that the Representatives have been authorized, for their own accounts and for the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Securities that the Underwriters have agreed to purchase. The Representatives may (but shall not be obligated to) make payment for any Securities to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the Closing Date for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(e) Delivery of the Securities. The Company shall deliver, or cause to be delivered, to the Representatives for the accounts of the several Underwriters the Firm Securities at the Closing Date, and the Additional Securities at the Optional Closing Date, if any, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The Firm Securities, and, if applicable, the Additional Securities, shall be in such denominations and registered in such names and denominations as the Representatives shall have requested at least two full business days prior to the Closing Date or the Optional Closing Date, as the case may be, and shall be made available for inspection on the business day preceding the Closing Date or the Optional Closing Date, as the case may be, at a location in New York City, as the Representatives may designate. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

Section 3. Additional Covenants. The Company further covenants and agrees with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430B of the Securities Act Regulations, and will promptly notify the Representatives, and confirm the notice in writing, of (i) the effectiveness of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Preliminary Prospectus or the Prospectus, (ii) the receipt of any comments from the Commission during the Prospectus Delivery Period (defined below), (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Preliminary Prospectus or the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Preliminary Prospectus or the Prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as it deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file such document. The Company will use its best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. During such period beginning on the date of this Agreement and ending on the later of the Closing Date or such date as, in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales of the Securities by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Securities Act Regulations (the “Prospectus Delivery Period”), the Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the Securities Act Regulations), or any amendment, supplement or revision to the Disclosure Package or the Prospectus, whether pursuant to the Securities Act, the Exchange Act or otherwise, will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

(c) Delivery of Registration Statements. The Company will deliver to the Representatives and counsel for the Underwriters, without charge, as such Underwriter or counsel for the Underwriters may reasonably request, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts. The Registration Statement and each amendment thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company will deliver to each Underwriter, without charge, as many copies of the Preliminary Prospectus as such Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes of offering the Securities. The Company will furnish to each Underwriter, without charge, during the Prospectus Delivery Period, such number of copies of the Prospectus as such Underwriter may reasonably request. The Preliminary Prospectus and the Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the Securities Act and the Securities Act Regulations and the Exchange Act and the Exchange Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Registration Statement, the Disclosure Package and the Prospectus. If, during the Prospectus Delivery Period, any event or development shall occur or condition exist as a result of which the Disclosure Package or the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if, in the opinion of counsel for the Underwriters or for the Company, it shall be necessary to amend or supplement the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if in the opinion of either such counsel, it is otherwise necessary or advisable to amend or supplement the Registration Statement, the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, or to file a new registration statement containing the Prospectus, in order to comply with law, including in connection with the delivery of the Prospectus, the Company agrees to (i) notify the Representatives of any such event or condition and (ii) promptly prepare (subject to Section 3(b) and 3(m) hereof), file with the Commission (and use its best efforts to have any amendment to the Registration Statement or any new registration statement to be declared effective) and furnish at its own expense to the Underwriters and to dealers in such quantities as they may reasonably request, amendments or supplements to the Registration Statement, the Disclosure Package or the Prospectus, or any new registration statement, necessary in order to make the statements in the Disclosure Package or the Prospectus as so amended or supplemented, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading or so that the Registration Statement, the Disclosure Package or the Prospectus, as amended or supplemented, will comply with law.

(f) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Securities for sale under (or obtain exemptions from the application of) the state securities or blue sky laws of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. The Company shall not be required to qualify to transact business or to take any action that would subject it to general service of process in any such jurisdiction where it is not

presently qualified or where it would be subject to taxation as a foreign business. The Company will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

(g) Use of Proceeds. The Company shall apply the net proceeds from the sale of the Securities sold by it in the manner described under the caption “Use of Proceeds” in the Disclosure Package and the Prospectus.

(i) Underlying Securities. The Company will reserve and keep available at all times, free of pre-emptive rights, shares of Common Stock for the purpose of enabling the Company to satisfy all obligations to issue the Underlying Securities upon conversion of the Securities. The Company will use its best efforts to cause the Underlying Securities to be listed on the New York Stock Exchange.

(j) Periodic Reporting Obligations. During the Prospectus Delivery Period, the Company shall file, on a timely basis, with the Commission and the New York Stock Exchange all reports and documents required to be filed under the Exchange Act and the Exchange Act Regulations.

(k) Clear Market. Without the prior written consent of Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and X.X. Xxxxxx Securities Inc., the Company will not, during the period ending 30 days after the date of the Prospectus, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, (iii) file with the Commission a registration statement under the Securities Act relating to any additional shares of its Common Stock or securities convertible into, or exchangeable for, any shares of its Common Stock, or publicly disclose the intention to effect any transaction described in clause (i), (ii) or (iii), whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; provided that the foregoing shall not apply to (A) the sale of the Securities under this Agreement or the issuance of the Underlying Securities, (B) the sale of shares of Common Stock pursuant to the 1999 Dividend Reinvestment and Share Purchase Plan, (C) shares of Common Stock to be issued pursuant to the ProLogis 1997 Long Term Incentive Plan, the ProLogis 2006 Long Term Incentive Plan, the ProLogis Employee Share Purchase Plan, the ProLogis Share Option Plan for Outside Trustees, the ProLogis 2000 Share Option Plan for Outside Trustees or to pay the annual retainer to ProLogis outside trustees, (D) shares of Common Stock to be issued in connection with the conversion or redemption of units of limited partnership interest

(outstanding on the date hereof) of limited partnerships in which the Company or is directly or indirectly a general partner or the issuance of units of limited partnership interests in any such partnership that may be converted into, or redeemed for, shares of Common Stock, (E) the filing of any registration statement in respect of shares of Common Stock pursuant to a registration rights agreement by which the Company is bound on the date hereof, (F) the conversion of securities or the exercise of warrants outstanding on the date hereof, or (G) any announcement by the Company of, or the entering by the Company into agreements or the Company’s filing of a prospectus supplement with the Commission relating to, the adoption of, or increase in the number of shares of Common Stock subject to, an “at-the-market” equity issuance program.

(l) Final Term Sheet. The Company will prepare a final term sheet containing only a description of the Securities, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement. A form of the Final Term Sheet for the Securities is attached hereto as Exhibit D.

(m) Permitted Free Writing Prospectuses. The Company represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of any Issuer Free Writing Prospectuses identified in Annex I and Xxxxx XX to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. The Company consents to the use by any Underwriter of a free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433, and (b) contains only (i) information describing the preliminary terms of the Securities or their offering or (ii) information that describes the final terms of the Securities or their offering and that is included in the Final Term Sheet of the Company contemplated in Section 3(l); provided that each Underwriter severally covenants with the Company not to take any action without the Company’s consent that would result in a free writing prospectus being required to be filed with the Commission under Rule 433(d) under the Securities Act that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriters.

(n) Notice of Inability to Use Automatic Shelf Registration Statement Form. If at any time, when the Securities remain unsold by the Underwriters, the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement of post-effective amendment to be declared

effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

(o) Filing Fees. The Company agrees to pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1) of the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act.

The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities and will not take any action prohibited by Regulation M under the Exchange Act in connection with the distribution of the Securities contemplated hereby, provided, the Company makes no covenant as to any actions which may be taken by the Underwriters.

(q) Transfer Agent. The Company shall engage and maintain, at its expense, a registrar and transfer agent for the Common Stock.

(r) Conversion Price. Between the date hereof and the Closing Date, or the Optional Closing Date, as the case may be, the Company will not do or authorize any act or thing that would result in an adjustment of the conversion price, as defined in the Prospectus.

The Underwriters, may, in their sole discretion, waive in writing the performance by the Company of any one or more of the foregoing covenants or extend the time for their performance.

Section 4. Payment of Expenses. The Company agrees to pay all costs, fees and expenses incurred in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including without limitation (i) all expenses incident to the issuance and delivery of the Securities (including all printing and engraving costs), (ii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Securities to the Underwriters, (iii) all fees and expenses of the Company’s counsel, independent public or certified public accountants and other advisors to the Company, (iv) all costs and expenses incurred in connection with the preparation, printing, filing, shipping and distribution of the Registration Statement (including financial statements, exhibits, schedules, consents and certificates of experts), each Issuer Free Writing Prospectus, the Preliminary Prospectus and the Prospectus, and all amendments and supplements thereto, and this Agreement, the Indenture, the DTC Agreement and the Securities, (v) all filing fees, attorneys’ fees and expenses incurred by the Company or the Underwriters in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Securities for offer and sale under the state securities or blue sky laws, and, if requested by the Representatives, preparing a “Blue Sky Survey” or memorandum, and any supplements thereto, advising the Underwriters of such qualifications, registrations and

If this Agreement is terminated by the Representatives pursuant to Section 5 or Section 11, or if the sale to the Underwriters of the Firm Securities on the Closing Date, or of the Additional Securities on the Optional Closing Date, if any, is not consummated because of any refusal, inability or failure on the part of the Company to perform any agreement herein or to comply with any provision hereof, the Company agrees to reimburse the Representatives and the other Underwriters (or such Underwriters as have terminated this Agreement with respect to themselves), severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Representatives and the Underwriters in connection with the proposed purchase and the offering and sale of the Securities, including but not limited to reasonable fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

Section 7. Offering Restrictions.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), each Underwriter represents and agrees that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the Relevant Implementation Date) it has not made and will not make an offer of the Securities to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Securities which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of the Securities to the public in that Relevant Member State at any time:

(a) to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities;

(b) to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts;

(c) to fewer than 100 natural or legal persons (other than qualified investors as defined in the Prospectus Directive) subject to obtaining the prior consent of representative of any such offer; or

(d) in any other circumstances which do not require the publication by the Issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of notes to the public” in relation to any Securities in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase or subscribe the Securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/ EC and includes any relevant implementing measure in each Relevant Member State.

Each Underwriter further represents and agrees that:

(a) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000 (“FSMA”)) received by it in connection with the issue or sale of the Securities in circumstances in which Section 21(1) of the FSMA would not, if the Issuer was not an authorised person, apply to the Company; and

(b) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Securities, from or otherwise involving the United Kingdom.

Section 8. Indemnification.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or

alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact, in each case, necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; or (iv) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; and to reimburse each Underwriter and each such officer, employee and controlling person for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Representatives) as such expenses are reasonably incurred by such Underwriter or such officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use in the Registration Statement (or any amendment thereto), any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company, its Trustees and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its trustees, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company or any such trustee, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use therein; and to reimburse the Company, or any such trustee, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such trustee, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss,

claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (the Representatives in the case of Section 8(b) and Section 9), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such

indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement; provided, that if it is ultimately determined that an indemnified party was not entitled to indemnification hereunder, such indemnified party shall be responsible for repaying or reimbursing such amounts to the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

Section 9. Contribution. If the indemnification provided for in Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus, bear to the aggregate initial public offering price of the Securities. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice

shall be required with respect to any action for which notice has been given under Section 8(c) for purposes of indemnification.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each officer and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each trustee of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

Section 10. Default of One or More of the Several Underwriters. If, on the Closing Date or the Optional Closing Date, if any, any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities, which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Securities, to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportion to the aggregate principal amounts of the Firm Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of the Firm Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase such Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase such Firm Securities and the aggregate principal amount of such Firm Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Firm Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 6, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus or any other documents or arrangements may be effected. If, on an Optional Closing Date, any one or more of the Underwriters shall fail or refuse to purchase such Additional

Securities and the aggregate principal amount of such Additional Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Additional Securities to be purchased on such date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Securities to be sold on such Optional Closing Date or (ii) purchase not less than the number of Additional Securities that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 11. Termination of this Agreement. On or after the Initial Sale Time and prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company if at any time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the New York Stock Exchange, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or FINRA; (ii) a general banking moratorium shall have been declared by any of federal or New York authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving the United States, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Securities in the manner and on the terms described in the Disclosure Package and the Prospectus or to enforce contracts for the sale of securities; (iv) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (v) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the United States. Any termination pursuant to this Section 11 shall be without liability on the part of (a) the Company to any Underwriter, except that the Company shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Sections 4 and 6 hereof, (b) any Underwriter to the Company, or (c) of any party hereto to any other party except that the provisions of Section 8 and Section 9 shall at all times be effective and shall survive such termination.

Section 12. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of its or their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

The term “successors” shall not include any purchaser of the Securities as such from any of the Underwriters merely by reason of such purchase.

Section 15. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof.

Section 16. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

Section 17. No Fiduciary Duty. The Company acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Underwriters, or any of them, with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

Section 18. USA Patriot Act. The Company acknowledges that in accordance with the requirements of the USA Patriot Act (Title III of Pub.

Section 19. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Table of Contents and the Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Annex I-1

EXHIBIT A

Opinion of counsel for the Company to be delivered pursuant to Section 5(f) of the Underwriting Agreement.

References to the Preliminary Prospectus or the Prospectus in this Exhibit A include any supplements thereto at the Closing Date.

(i) The Company has been duly organized and is validly existing as a real estate investment trust in good standing under the laws of the State of Maryland and has the trust power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package and the Prospectus and to enter into and perform its obligations under each of this Agreement, the Securities, the Indenture and the Borrower Pledge Agreement. The Company is duly qualified to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change.

(ii) Each of Palmtree Acquisition Corporation, ProLogis Japan Incorporated and Catellus Operating Limited Partnership (each a “Significant Subsidiary Pledgor” and collectively the “Significant Subsidiary Pledgors”) is validly existing and in good standing under the laws of the State of Delaware and has the power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package and the Prospectus and to enter into and perform its obligations under its respective Pledge Agreement. Each Significant Subsidiary Pledgor is duly qualified to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change.

(iii) This Agreement has been duly authorized, executed and delivered by the Company.

(iv) The Base Indenture has been duly qualified under the Trust Indenture Act and has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

(v) Each of the First Supplemental Indenture, the Second Supplemental Indenture, the Third Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth Supplemental Indenture, the Sixth Supplemental Indenture, the Seventh Supplemental Indenture, the Eighth Supplemental Indenture, the Ninth Supplemental Indenture and the Tenth Supplemental Indenture, has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

A-1

(vi) The Securities have been duly authorized for issuance and sale pursuant to this Agreement and the Indenture and, when executed by the Company and authenticated by the Trustee in the manner provided for in the Indenture and delivered against payment of the purchase price therefor in accordance with the terms of this Agreement, will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles, and will be entitled to the benefits of the Indenture.

(vii) The Underlying Securities reserved for issuance upon conversion of the Securities have been duly authorized and reserved and, when issued upon conversion of the Securities in accordance with the terms of the Securities, will be validly issued, fully paid and non-assessable and the issuance of the Underlying Securities will not be subject to any preemptive or similar rights under the Company’s charter or bylaws or under Maryland law.

(viii) Each of the Company and each Significant Subsidiary Pledgor has duly authorized, executed and delivered the Pledge Agreement to which it is a party.

(ix) Each Pledge Agreement constitutes a valid and binding agreement of each Pledgor that is party thereto, enforceable against such Pledgor in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

(x) The Security Agency Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company, enforceable against it in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles. In rendering such opinion, such counsel need only opine as to the enforceability against the Company of Section 9(c) thereof.

(xi) Each Pledge Agreement is effective to create a security interest under Article 9 of the Uniform Commercial Code as currently in effect in the State of New York (the “UCC”) to the extent a security interest can be created thereunder in the collateral covered thereby (any such collateral, “Article 9 Collateral”).

(xii) Pursuant to Section 9-301 of the NY UCC, the local law of the jurisdiction where instruments are actually located governs perfection of a possessory security interest in such instruments. Assuming the Collateral Agent takes and retains possession (as such term is used in Section 9-313(a) of the NY UCC) in the State of New York of the instruments pledged to the Collateral Agent pursuant to each Pledge Agreement (the “Pledged Securities”), and further assuming the Pledged Securities are each duly indorsed to the Collateral Agent or in blank by an effective indorsement, the Collateral Agent’s security interest in the rights of each Pledgor in the applicable Pledged Securities will be perfected under the NY UCC.

A-2

(xiii) Under the NY UCC (including the choice of laws provisions thereof), the local law of the jurisdiction where a debtor is “located” governs (with certain exceptions not relevant to this opinion) perfection of a nonpossessory security interest in any Article 9 Collateral in which a security interest may be perfected by filing a financing statement under the Uniform Commercial Code as in effect in the U.S. State of filing (any such collateral, “Filing Collateral”). Under the NY UCC (including the choice of laws provisions thereof), (1) the U.S. State that is the jurisdiction of formation of a U.S. Pledgor (a “Formation State”) is the “location” for such U.S. Pledgor and, therefore, the local laws of such Formation State govern perfection by the filing of financing statements of a security interest in such U.S. Pledgor’s rights in its Filing Collateral; (2) assuming that each Foreign Pledgor’s only place of business or its chief executive office is located in the country in which such Foreign Pledgor was organized or formed and the law of such country does not require information concerning the existence of a nonpossessory security interest to be made generally available in a filing, recording or registration system as a condition or result of the security interest’s obtaining priority over the rights of a lien creditor with respect to such Foreign Pledgor’s Article 9 Collateral (as to which we express no opinion), then the District of Columbia is the “location” of such Foreign Pledgor and, therefore, the local laws of the District of Columbia govern perfection by the filing of financing statements of a security interest in such Foreign Pledgor’s rights in its Filing Collateral and (3) assuming that each Foreign Pledgor’s only place of business or its chief executive office is located in Colorado, then such Foreign Pledgor is “located” in Colorado and the local law of Colorado governs perfection of a nonpossessory security interest in such Foreign Pledgor’s rights in its Filing Collateral.

Based on the foregoing, and assuming that each Financing Statement was filed (within the meaning of Section 9-516 of the applicable Uniform Commercial Code) in the form attached to such opinion (with all relevant attachments) in the filing office listed thereon, is currently of record in such filing office and has not been terminated or amended, the security interest of the Collateral Agent in the Filing Collateral of each Pledgor listed on the applicable Financing Statement is perfected under the Uniform Commercial Code as currently in effect (x) in the case of each U.S. Pledgor, the applicable Formation State; and (y) in the case of each Foreign Pledgor, the District of Columbia or Colorado, as applicable.

(xiv) The Registration Statement became effective upon filing with the Commission pursuant to Rule 462(e) under the Securities Act. To the best knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for such purpose have been instituted or are pending or are contemplated or threatened by the Commission. Any required filing of the Preliminary Prospectus and the Prospectus and any supplement thereto pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such Rule 424(b).

(xv) The Registration Statement, the Prospectus, including any document incorporated by reference therein, and each amendment or supplement to the Registration Statement and the Prospectus, including any document incorporated by reference therein (other than the financial statements and supporting schedules included or incorporated by reference therein or in exhibits to or excluded from the Registration Statement and other than the Form T-1, as to which no opinion need be rendered), when they became effective or were filed with the Commission, as

A-3

the case may be, complied as to form in all material respects with the applicable requirements of the Securities Act, the Exchange Act and the Trust Indenture Act.

(xvi) The Securities, the Indenture and the Security Documents conform in all material respects to the descriptions thereof contained in the Disclosure Package and the Prospectus.

(xvii) The statements (A) in the Base Prospectus under the captions “Description of Debt Securities,” “Description of Common Shares” and “Federal Income Tax Considerations,” (B) in each of the Preliminary Prospectus Supplement and the Prospectus Supplement under the captions “Risk Factors—We cannot assure you that we will not be required to withhold on payments to Non-U.S. Holders of notes in connection with a sale, exchange, redemption, repurchase, conversion, or other disposition of notes based on the facts and circumstances at the time,” “Description of Notes” and “Certain U.S. Federal Income Tax Considerations,” (C) incorporated by reference in the Preliminary Prospectus and the Prospectus from Item 3 of Part I of the Company’s Annual Report on Form 10-K, and (D) in the Item 15 of the Registration Statement, in each case insofar as such statements constitute a summary of the legal matters, documents or proceedings referred to therein has been reviewed by such counsel and fairly present and summarize, in all material respects, the matters referred to therein.

(xviii) No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental authority or agency, is required for the Company’s execution, delivery and performance of the Agreement and the Indenture and consummation of the transactions contemplated thereby and by the Disclosure Package and the Prospectus (including the issuance and delivery of the Securities and the issuance of the Underlying Securities upon conversion thereof) and the execution, delivery and performance by any U.S. Pledgor of the Pledge Agreement to which it is a party, except (A) such as have been obtained or made by the Company and are in full force and effect under the Securities Act, Trust Indenture Act, applicable state securities or blue sky laws and from the FINRA, (B) the filing of financing statements in the offices specified in paragraph (xii) above and (C) consents the failure of which to obtain would not result in a Material Adverse Change or have a material adverse effect on the transactions contemplated by this Agreement or the Indenture or on the validity and enforceability of the Securities and the Indenture.

(xix) The execution and delivery of each of the Agreement and the Indenture by the Company and the execution and delivery of the applicable Pledge Agreements by the Company and the Pledgors, and the execution, issuance and delivery of the Securities (including the issuance of the Underlying Securities upon conversion thereof) by the Company and the performance by the Company and the Pledgors, as applicable, of their respective obligations thereunder (other than performance by the Company of its obligations under the indemnification section of the Agreement, as to which no opinion need be rendered) (A) will not result in any violation of the provisions of the declaration of trust (or charter or by-laws or other similar constitutive documents) of the Company, any U.S. Significant Subsidiary or any Significant Subsidiary Pledgor; (B) will not constitute a breach of, or Default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company, U.S. Significant Subsidiary or any Pledgor (other than under the Pledge Agreements) pursuant to (x) the Global Senior Credit Agreement (other than with respect to compliance by the Company or any subsidiary with any financial covenants as to which no opinion need be rendered), or (z)

A-4

to the best knowledge of such counsel, any other material Existing Instrument; or (C) to the best knowledge of such counsel, will not result in any violation of any law, administrative regulation or administrative or court decree applicable to the Company, U.S. Significant Subsidiary or any Pledgor, other than in the case of clauses (B) and (C), such Defaults and violations as would not, individually or in the aggregate, result in a Material Adverse Change.

(xx) The Company is not, and after receipt of payment for the Securities and the application of the proceeds as described in the Disclosure Package and the Prospectus under “Use of Proceeds” will not be, an “investment company” within the meaning of Investment Company Act.

(xxi) The Company has qualified to be taxed as a real estate investment trust pursuant to the Internal Revenue Code for its taxable years ended December 31, 2006, 2007, 2008 and 2009 and the Company’s present organization, ownership, the Company’s present and proposed method of operation, assets and income are such that the Company is in a position under present law to so qualify for the fiscal year ended December 31, 2010 and in the future.

(xxii) The investments of the Company described in the Disclosure Package and the Prospectus are permitted investments under the declaration of trust of the Company.

In addition, such counsel shall state that they have examined various documents and records and participated in conferences with officers and other representatives of the Company, representatives of the independent public or certified public accountants for the Company and with representatives of the Underwriters at which the contents of the Registration Statement, the Disclosure Package and the Prospectus, and any supplements or amendments thereto, and related matters were discussed and, although such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Disclosure Package or the Prospectus, including the documents incorporated by reference therein (other than as specified above), and any supplements or amendments thereto, on the basis of the foregoing, no facts came to their attention that caused them to believe that (i) the Registration Statement or any amendments thereto, at the most recent deemed effective date pursuant to Rule 430B(f)(2) under the Securities Act prior to the Initial Sale Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) the Prospectus, as of its date or at the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) the Disclosure Package as of the Initial Sale Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of circumstances under which they were made, not misleading (except for the Form T-1 and the financial statements, supporting schedules and other financial or statistical data included or incorporated by reference therein or derived or omitted therefrom as to which such counsel need express no belief).

Use of Proceeds:		ProLogis intends to use the net proceeds from the sale of the notes and the concurrent offering of the 2017 notes and 2020 notes for the repayment of borrowings under its global credit agreement. ProLogis expects to reborrow under its global credit agreement to fund the cash purchase of certain of its senior notes that are tendered pursuant to its offer to purchase such notes, which commenced on March 8, 2010, for the repayment or repurchase of other indebtedness and for general corporate purposes.

Trade Date:		March 10, 2010

Settlement Date:		It is expected that delivery of the securities will be made against payment therefor on or about the March 16, 2010 (T+4), which will be the fourth business day following the date of pricing of the notes (this settlement cycle being referred to

Exh. D-3


		as “T+4”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade securities on the date of this term sheet or the next succeeding business day will be required, by virtue of the fact that the securities initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement.

The foregoing sentence shall not apply to (i) the transfer of shares of Common Stock under the ProLogis 401(k) Savings Plan and Trust pursuant to elections made by the undersigned, (ii) dispositions of shares of Common Stock effected pursuant to a written plan meeting the requirements of Rule 10b5-1 promulgated under the Securities Act of 1933, as amended, provided that such plan was entered into prior to the date hereof, and (iii) transfers of Common Stock by gift, will or intestacy, including without limitation transfers by gift, will or intestacy to family members of the undersigned or to a settlement or trust established under the laws of any country for the benefit of the undersigned and/or family members of the undersigned, provided that in the event of any such transfer described in this clause (iii), the transferee shall enter into a lock-up agreement substantially in the form of this Letter Agreement covering the remainder of the 30-day period referred to herein. In addition, the undersigned agrees that, without the prior written consent of Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and X.X. Xxxxxx Securities Inc., it will not, during the period commencing on the date hereof and ending 30 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.
