Incorporated is acting as representative (in such capacity, the “Representative”), with respect to the sale by the Operating Partnership and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amount of the securities opposite the names of the Underwriters listed on Schedule A hereto (the “Securities”). The Securities will be issued pursuant to an indenture, dated as of August 29, 2000 (the “Indenture”), between the Operating Partnership and U.S. Bank Trust National Association, as trustee (the “Trustee”). The Securities will be issued in book-entry form only to Cede & Co. as nominee of The Depository Trust Company (“DTC”) pursuant to a letter agreement, to be dated as of the Closing Time (as defined in Section 2(b)) (the “DTC Agreement”), among the Operating Partnership, the Trustee and DTC. Unless the context otherwise requires, as used herein, “you” and “your” shall mean the parties to whom this Underwriting Agreement (this “Agreement”) is addressed. Capitalized terms used herein without definition shall have the meanings assigned to such terms in the Prospectus (as defined below) relating to the Securities.

The Operating Partnership understands that the Underwriters propose to make a public offering of the Securities as soon as the Representative deems advisable after this Agreement has been executed.

The Operating Partnership has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-43530) covering the registration of debt securities, including the Securities, under the Securities Act of 1933, as amended (the “1933 Act”), including the related preliminary prospectus or prospectuses. Promptly after execution and delivery of this Agreement, the Operating Partnership will prepare and file a prospectus supplement relating to the Securities in accordance with the provisions of Rule 424(b) (“Rule 424(b)”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Any prospectus supplement relating to the Securities that omitted certain pricing information and was used after the effectiveness of such registration statement and prior to the execution and delivery of this Agreement and the prospectus contained in such registration statement are collectively referred to herein as a “preliminary prospectus.” Such registration statement, including the exhibits thereto, schedules thereto, if any, and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, at the time it became effective, is herein called the “Registration Statement.” Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the “Rule 462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The final prospectus and the prospectus supplement relating to the Securities, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, in the form first furnished to the Underwriters for use in connection with confirming sales of the Securities, are collectively referred to herein as the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus or the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “set forth” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), which is incorporated by reference in the Registration Statement, such preliminary prospectus or the Prospectus, as the case may be.

The “Company” shall mean Equity Office Properties Trust, a Maryland real estate investment trust, which is the general partner of the Operating Partnership.

Section 3. Covenants of the Operating Partnership. The Operating Partnership covenants with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. During the period when the Prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, the Operating Partnership will notify the Representative immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any amendment or supplement to the Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, and (iv) of 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 any preliminary 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 Operating Partnership will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort 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 the period when the Prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, the Operating Partnership will give the Representative notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Representative 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 Representative or counsel for the Underwriters shall object.

(c) Delivery of Registration Statements. The Operating Partnership has furnished or will deliver to the Representative and counsel for the Underwriters, without charge, conformed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein) and conformed copies of all consents and certificates of experts, and will also deliver to the Representative, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the 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 Operating Partnership has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus, if any, as such Underwriter reasonably requested, and the Operating Partnership hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Operating Partnership will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the 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 Operating Partnership will comply with the 1933 Act and the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations and the 1939 Act and the 1939 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Operating Partnership, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Operating Partnership will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Operating Partnership will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) State Law. The Operating Partnership will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions, including real estate syndication laws, as the Representative may designate and to maintain such qualifications in effect for a period of not less than one year from the later of the effective date of the Registration Statement and any Rule 462(b) Registration Statement; provided, however, that the Operating Partnership shall not be obligated to file any general consent to service of process or to qualify as a foreign limited partnership or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Operating Partnership will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement and any Rule 462(b) Registration Statement. The Operating Partnership will also supply the Underwriters with such information as is necessary for the determination of the legality of the Securities for investment under the laws of such jurisdictions as the Underwriters may request.

(g) Rule 158. The Operating Partnership will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(h) Use of Proceeds. The Operating Partnership will use the net proceeds received by it from the sale of the Securities in the manner specified in the Prospectus under “Use of Proceeds.”

(i) Reporting Requirements. The Operating Partnership, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(j) DTC. The Operating Partnership shall use its reasonable best efforts in cooperation with the Underwriters to permit the Securities to be eligible for clearance and settlement through DTC.

(k) Ratings. The Operating Partnership will use its reasonable best efforts to enable Standard & Poor’s Ratings Services (“S&P”) and Xxxxx’x Investors Service, Inc. (“Moody’s”) to provide their respective credit ratings of the Securities.

(l) Notification of Certain Events. Prior to the Closing Time, the Operating Partnership will notify the Representative in writing immediately if any event occurs that renders any of the representations and warranties of the Operating Partnership contained herein inaccurate or incomplete.

Section 4. Payment of Fees and Expenses.

(a) Expenses. The Operating Partnership will pay all expenses incident to the performance of its obligations under this Agreement, including (i) the preparation and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment and supplement thereto, (ii) the preparation and delivery to the Underwriters of this Agreement, any Agreement among Underwriters, the Indenture, and such other documents as may be required in connection with the offering, purchase, sale and delivery of the Securities, including any global securities, (iii) the preparation, issuance and delivery of the Securities, including any global Securities, (iv) the fees and disbursements of the Operating Partnership’s counsel, accountants, and other advisors or agents (including transfer agents and registrars), (v) the qualification of the Securities under state securities laws and real estate syndication laws in accordance with the provisions of Section 3(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the preparation, printing and delivery of a blue sky memorandum (the “Blue Sky Memorandum”) and any amendment or supplement thereto, (vi) the printing and delivery to the Underwriters of copies of each preliminary prospectus and the Prospectus and any amendments or supplements thereto, (vii) any fees charged by nationally recognized statistical rating organizations for the rating of the Securities, (viii) the fees and expenses of the Trustee, including the reasonable fees and disbursements of counsel for the Trustee, in connection with

Section 5. Conditions of Underwriters’ Obligations.

Section 6. Indemnification.

(a) Indemnification of Underwriters. The Operating Partnership agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any director, officer, employee or affiliate thereof, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of 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 arising out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Operating Partnership; and

(iii) against any and all expense whatsoever (including, without limitation, the reasonable fees and disbursements of counsel chosen by the Representative), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information

furnished to the Operating Partnership by any Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Operating Partnership. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Operating Partnership, and each person, if any, who controls the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any trustee, officer, employee or affiliate thereof, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information concerning such Underwriter furnished to the Operating Partnership through the Representative by or on behalf of such Underwriter expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representative, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Operating Partnership. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim 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.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any

settlement of the nature contemplated by Section 6(a)(iii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

Section 7. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 hereof is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Operating Partnership, on the one hand, and the Underwriters, on the other, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Operating Partnership and the Underwriters, as incurred, in such proportions that the Underwriters are responsible for that portion represented by the percentage that the discounts and commissions appearing on the cover page of the Prospectus bears to the price to investors of the applicable series of Securities appearing thereon and the Operating Partnership is responsible for the balance; provided, however, that 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.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each trustee of the Company, and each person, if any, who controls the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Operating Partnership. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased and sold by it to purchasers exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission in the Prospectus.

Section 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company, on behalf of the Operating Partnership, submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriters or any controlling person, or by or on behalf of the Operating Partnership or any controlling person, and shall survive delivery of the Securities to the Underwriters.

Section 9. Termination of Agreement.

(a) The Representative may terminate this Agreement, by notice to the Operating Partnership, at any time at or prior to the Closing Time, (i) if there has been, since the date of this Agreement or since the respective dates as of which information is given in the Prospectus, any Material Adverse Change, (ii) if there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial, or economic conditions, in each case, the effect of which is such as to make it, in the Representative’s reasonable judgment, impracticable to market the Securities or enforce contracts for the sale of the Securities, (iii) if trading in any of the Company’s shares of beneficial interest or the Operating Partnership’s debt securities has been suspended by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq Stock Market has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc., or any other governmental authority, or (iv) if a banking moratorium has been declared by either federal, New York, Delaware or Maryland authorities.

(b) If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Sections 4 and 10 hereof and provided further that Sections 4, 6, 7, 8 and 13 hereof shall survive such termination and remain in full force and effect.

Section 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(a) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased hereunder, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective purchase obligations hereunder bear to the purchase obligations of all non-defaulting Underwriters.

(b) if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representative or the Operating Partnership shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term ” Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representative at 0000 Xxxxxxxx, 0xx Xxxxx, Xxx Xxxx, XX, 00000, attention of Xxxxxxx Xxxxx; and notices to the Operating Partnership shall be directed to it at Two North Xxxxxxxxx Xxxxx, Xxxxx 0000, Xxxxxxx, XX 00000, attention of Xxxxxxx X. Xxxxxxx, Chief Legal Counsel.

Section 12. Parties. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Operating Partnership and their respective successors and the controlling persons and officers and trustees referred to in Sections 6 and 7 and their successors, heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors and said controlling persons and officers and directors and their successors, heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

Section 13. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

Section 14. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall constitute a single instrument.

Section 15. Effect of Headings. The Article, Section and Sub-Section headings herein are for convenience only and shall not affect the construction hereof.
