Ladies and Gentlemen:

CarrAmerica Realty Operating Partnership, L.P., a Delaware limited partnership (the “Operating Partnership”), may from time to time offer in one or more series its unsecured debt securities (“Debt Securities”) with an aggregate public offering price of up to $1,000,000,000 (or its equivalent in another currency based on the exchange rate at the time of sale) in amounts, at prices and on terms to be determined at the time of offering. The Debt Securities may be offered, separately or together, in separate series in amounts, at prices and on terms to be set forth in one or more Prospectus Supplements as hereinafter defined. The Debt Securities will be issued under one or more indentures, as amended or supplemented (each, an “Indenture”), between the Operating Partnership and a trustee (a “Trustee”). The Debt Securities may be guaranteed (the “Guarantees”) as to payments of principal, interest and premium, if any, by one or both of CarrAmerica Realty Corporation, a Maryland corporation (the “Company”) or CarrAmerica Realty, L.P., a Delaware limited partnership (“CarrAmerica L.P.” and together with the Company, the “Guarantors”). Each series of Debt Securities may vary as to aggregate principal amount, maturity date, interest rate or formula and timing of payments thereof, redemption or repayment provisions, conversion provisions and any other variable terms which the Indenture contemplates may be set forth in the Debt Securities as issued from time to time. As used herein, “the Representatives,” unless the context otherwise requires, shall mean the parties to whom this Agreement is addressed together with the other parties, if any, identified in the applicable Terms Agreement (as hereinafter defined) as additional co-managers with respect to Underwritten Securities (as hereinafter defined) purchased pursuant thereto.

Whenever the Operating Partnership determines to make an offering of Debt Securities through the Representatives or through an underwriting syndicate managed by the Representatives, the Operating Partnership will enter into an agreement (the “Terms Agreement”) providing for the sale of such Debt Securities (the “Underwritten Securities”) to, and the purchase and offering thereof by, the Representatives and such other underwriters, if any, selected by the Representatives as have authorized the Representatives to enter into such Terms Agreement on their behalf (the “Underwriters,” which term shall include the Representatives whether acting alone in the sale of the Underwritten Securities or as a member of an underwriting syndicate and any Underwriter substituted pursuant to Section 9 hereof). The Terms Agreement relating to the offering of Underwritten Securities shall specify the amount of Underwritten Securities to be issued, the names of the Underwriters participating in such offering (subject to substitution as provided in Section 9 hereof), the amount of Underwritten Securities which each such Underwriter severally agrees to purchase, the names of such of the Representatives or such other Underwriters acting as co-managers, if any, in connection with such offering, the price at which the Underwritten Securities are to be purchased by the Underwriters from the Operating Partnership, the

initial public offering price, if any, of the Underwritten Securities, the time and place of delivery and payment and any other variable terms of the Underwritten Securities (including, but not limited to, current ratings, denominations, interest rates or formulas, interest payment dates, maturity dates and conversion, redemption or repayment provisions applicable to the Underwritten Securities). The Terms Agreement, which shall be substantially in the form of Exhibit A hereto, may take the form of an exchange of any standard form of written telecommunication between the Representatives and the Operating Partnership. Each offering of Underwritten Securities through the Representatives or through an underwriting syndicate managed by the Representatives will be governed by this Agreement, as supplemented by the applicable Terms Agreement.

The Operating Partnership and the Guarantors have filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-114049) for the registration of the Debt Securities and the Guarantees under the Securities Act of 1933, as amended (the “1933 Act”), and the offering thereof from time to time in accordance with Rule 430A or Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”), and the Operating Partnership and the Guarantors have filed such amendments thereto as may have been required prior to the execution of the applicable Terms Agreement. Such registration statement (as amended, if applicable) has been declared effective by the Commission and an Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”). Such registration statement and the prospectus constituting a part thereof (including in each case the information, if any, deemed to be part thereof pursuant to Rule 430A(b) of the 1933 Act Regulations), and each prospectus supplement relating to the offering of Underwritten Securities pursuant to Rule 415 of the 1933 Act Regulations (the “Prospectus Supplement”), including all documents incorporated therein by reference, as from time to time amended or supplemented pursuant to the 1933 Act, the Securities Exchange Act of 1934, as amended (the “1934 Act”) or otherwise, are collectively referred to herein as the “Registration Statement” and the “Prospectus,” respectively; provided that if any revised Prospectus shall be provided to the Representatives by the Operating Partnership for use in connection with the offering of Underwritten Securities which differs from the Prospectus on file at the Commission at the time the Registration Statement becomes effective (whether or not such revised prospectus is required to be filed by the Operating Partnership pursuant to Rule 424(b) of the 1933 Act Regulations), the term “Prospectus” shall refer to each such revised prospectus from and after the time it is first provided to the Representatives for such use; provided, further, that a Prospectus Supplement shall be deemed to have supplemented the Prospectus only with respect to the offering of Underwritten Securities to which it relates. Any registration statement (including any supplement thereto or information which is deemed part thereof) filed by the Operating Partnership and the Guarantors under Rule 462(b) of the 1933 Act Regulations (a “Rule 462(b) Registration Statement”) shall be deemed to be part of the Registration Statement. Any prospectus (including any amendment or supplement thereto or information which is deemed part thereof) included in the Rule 462(b) Registration Statement and any term sheet as contemplated by Rule 434 of the 1933 Act Regulations (a “Term Sheet”) shall be deemed to be part of the Prospectus. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement or the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement or the Prospectus shall be deemed to mean and include the filing of any document under the 1934 Act which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, preliminary prospectus supplement, Prospectus or Prospectus Supplement or any Term Sheet or any amendment or supplement to the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval System.

(xxxii) Each of the Operating Partnership and the Subsidiaries is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which they are engaged; and none of the Operating Partnership and the Subsidiaries has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its businesses at a cost that would not have a Material Adverse Effect, except as described in or contemplated by the Registration Statement and the Prospectus.

(xxxiii) The Operating Partnership has not taken and will not take, directly or indirectly, any action prohibited by Regulation M under the 1934 Act.

SECTION 2. Sale and Delivery to the Underwriters; Closing.

(b) Payment of the purchase price for, and delivery of the Underwritten Securities to be purchased by the Underwriters shall be made at the offices of Clifford Chance US LLP, 31 West 52^nd

Street, New York, New York 10019, or at such other place as shall be agreed upon by the Representatives and the Operating Partnership at 9:30 a.m. on the fourth business day (or the third business day if required under Rule 15c6-1 of the 1934 Act, or unless postponed in accordance with the provisions of Section 9) following the date of the applicable Terms Agreement or at such other time as shall be agreed upon by the Representatives and the Operating Partnership (each referred to herein as a “Closing Time”). Unless otherwise specified in the applicable Terms Agreement, payment shall be made to the Operating Partnership by wire transfer of Federal or similar same day funds payable to the order of the Operating Partnership against delivery to the Representatives for the respective accounts of the Underwriters of certificates for the Underwritten Securities to be purchased by them. The Underwritten Securities shall be in such denominations and registered in such names as the Representatives may request in writing at least two business days before the Closing Time. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Underwritten Securities which it has agreed to purchase. The Representatives, individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Underwritten Securities to be purchased by any Underwriter whose funds have not been received by the Closing Time but any such payment shall not relieve such Underwriter from its obligations hereunder. The notes for the Underwritten Securities will be made available for examination and packaging by the Representatives not later than 10:00 a.m. on the last business day prior to the Closing Time in New York, New York.

SECTION 3. Covenants of the Operating Partnership. The Operating Partnership covenants with the Representatives and with each Underwriter participating in the offering of Underwritten Securities, as follows:

(a) In respect to each offering of Underwritten Securities, the Operating Partnership will prepare a Prospectus Supplement setting forth the number of Underwritten Securities covered thereby and their terms not otherwise specified in the Prospectus pursuant to which the Underwritten Securities are being issued, the names of the Underwriters participating in the offering and the number of Underwritten Securities which each severally has agreed to purchase, the names of the Underwriters acting as co-managers in connection with the offering, the price at which the Underwritten Securities are to be purchased by the Underwriters from the Operating Partnership, the initial public offering price, if any, the selling concession and reallowance, if any, and such other information as the Representatives and the Operating Partnership deem appropriate in connection with the offering of the Underwritten Securities; and the Operating Partnership will promptly transmit copies of the Prospectus Supplement to the Commission for filing pursuant to Rule 424(b) of the 1933 Act Regulations and will furnish to the Underwriters named therein as many copies of the Prospectus (including such Prospectus Supplement) as the Representatives shall reasonably request.

(b) If, at the time the Prospectus Supplement was filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations, any information shall have been omitted therefrom in reliance upon Rule 430A of the 1933 Act Regulations, then not later than the second business day following the execution and delivery of the Terms Agreement, or, if applicable, such earlier time as may be required by Rule 430A(a)(3) of the 1933 Act Regulations, the Operating Partnership will prepare, and file or transmit for filing with the Commission in accordance with such Rule 430A and Rule 424(b) of the 1933 Act Regulations, a copy of an amended Prospectus, or, if required by such Rule 430A, a post-effective amendment to the Registration Statement (including amended Prospectuses), containing all information so omitted. If required, the Operating Partnership will prepare and file or transmit for filing a Rule 462(b) Registration Statement by 10:00 p.m. on the date of execution of the Terms Agreement. If a Rule 462(b) Registration Statement is filed, the Operating Partnership shall make payment of, or arrange for payment of, the additional registration fee owing to the Commission required by Rule 111 of the 1933 Act Regulations.

(c) The Operating Partnership will notify the Representatives immediately, and confirm such notice in writing, of (i) the effectiveness of any amendment to the Registration Statement, (ii) the transmittal to the Commission for filing of any Prospectus Supplement or other supplement or amendment to the Prospectus to be filed pursuant to the 1933 Act, (iii) the receipt of any comments from the Commission, (iv) 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 (v) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; and the Operating Partnership will make every reasonable effort to prevent the issuance of any such stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(d) At any time when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act in connection with sales of the Underwritten Securities, the Operating Partnership will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement or any amendment or supplement to the Prospectus, whether pursuant to the 1933 Act, 1934 Act or otherwise, will furnish the Representatives with copies of any such amendment or supplement a reasonable amount of time prior to such proposed filing and, unless required by law, will not file or use any such amendment or supplement or other documents in a form to which the Representatives or counsel for the Underwriters shall reasonably object.

(e) The Operating Partnership will furnish to each Underwriter, from time to time 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 the Underwriters may reasonably request for the purposes contemplated by the 1933 Act or the 1934 Act or the respective applicable rules and regulations of the Commission thereunder.

(f) If any event shall occur as a result of which it is necessary, in the reasonable opinion of the Representatives or counsel for the Underwriters, to amend or supplement the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, the Operating Partnership will forthwith amend or supplement the Prospectus (in form and substance reasonably satisfactory to the Representatives or counsel for the Underwriters, as the case may be) so that, as so amended or supplemented, the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered to a purchaser, not misleading, and the Operating Partnership will furnish to the Underwriters a reasonable number of copies of such amendment or supplement.

(g) The Operating Partnership will endeavor, in cooperation with the Underwriters, to qualify the Underwritten Securities for offering and sale under the applicable securities laws and real estate syndication laws of such states and other jurisdictions as the Representatives may designate; provided, however, that the Operating Partnership shall not be obligated to (i) qualify as a foreign limited partnership in a jurisdiction it is not so qualified, (ii) file any general consent to service of process or (iii) take any actions that would subject it to income taxation in any such jurisdiction. In each jurisdiction in which the Underwritten 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 so long as may be required for the distribution of the Underwritten Securities.

(h) With respect to each sale of Underwritten Securities, the Operating Partnership will make generally available to its security holders as soon as practicable, but not later than 90 days after the close of the period covered thereby, an earnings statement (in form complying with the provisions of Rule 158 of the 1933 Act Regulations) covering a twelve-month period beginning not later than the first day of the Operating Partnership’s fiscal quarter next following the “effective date” (as defined in said Rule 158) of the Registration Statement.

(k) The Operating Partnership will file with the New York Stock Exchange all documents and notices required by the New York Stock Exchange of companies that have securities listed on such exchange and, to the extent the Underwritten Securities are listed on the New York Stock Exchange, the Operating Partnership will use its best efforts to maintain the listing of such Underwritten Securities listed on the New York Stock Exchange.

(l) In respect to each offering of Debt Securities, the Operating Partnership will qualify an Indenture under the 1939 Act and will endeavor to have a Statement of Eligibility submitted on behalf of the Trustee.

(m) The Operating Partnership will take all reasonable action necessary to enable Standard & Poor’s Corporation (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) or any other nationally recognized statistical rating organization to provide their respective credit ratings of any Underwritten Securities, if applicable.

(n) During the period specified in the applicable Prospectus Supplement, neither the Company nor the Operating Partnership will, without the prior written consent of the Representatives, or any one Representative, if so provided in the Prospectus Supplement, directly or indirectly, sell, offer to sell, transfer, hypothecate, grant any option for the sale of, or otherwise dispose of any securities of the same series or ranking on a parity with any Underwritten Securities (other than the Underwritten Securities covered by such Prospectus Supplement) or any security convertible into or exchangeable for such Underwritten Securities.

(o) The Company will use its best efforts to continue to meet the requirements to qualify as a “real estate investment trust” under the Code.

(p) During the period from the Closing Time until five years after the Closing Time, the Operating Partnership will deliver to the Representatives, promptly upon their becoming available, copies of all current, regular and periodic reports of the Operating Partnership mailed to its unitholders or filed with any securities exchange or with the Commission or any governmental authority succeeding to any of the Commission’s functions.

(d) At the time of the execution of the applicable Terms Agreement, the Representatives shall have received from KPMG LLP a letter dated such date, in form and substance satisfactory to the Representatives, to the effect that: (i) they are independent public accountants with respect to the Operating Partnership and the Guarantors as required by the 1933 Act and the 1933 Act Regulations; (ii) it is their opinion that the financial statements and supporting schedules included in the Registration Statement, or incorporated by reference therein, and covered by their opinions therein comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations; (iii) based upon limited procedures set forth in detail in such letter, including a reading of the latest available interim financial statements of the Operating Partnership and the Guarantors, a reading of the minute books of the Operating Partnership and the Guarantors, inquiries of officials of the Operating Partnership and the Guarantors responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing has come to their attention which causes them to believe that (A) the unaudited financial statements of the Operating Partnership and the Guarantors included in the Registration Statement, or incorporated by reference therein, do not comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations, or material modifications are required for them to be presented in conformity with generally accepted accounting principles, (B) the operating data and balance sheet data set forth in the Prospectus under the caption “Selected Consolidated Financial Data”, if any, were not determined on a basis substantially consistent with that used in determining the corresponding amounts in the audited financial statements included or incorporated by reference in the Registration Statement, (C) the pro forma financial information, if any, included or incorporated by reference in the Registration Statement was not determined on a basis substantially consistent with that of the audited financial statements included or incorporated by reference in the Registration Statement or did not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X and that the pro forma adjustments have not been properly applied to the historical amounts in the compilations of the statements or (D) at a specified date not more than three business days prior to the date of the applicable Terms Agreement, there has been any change in the total partner’s or stockholder’s capital of the Operating Partnership or the Guarantors or any increase in the mortgages and notes payable to affiliates of the Operating Partnership or the Guarantors or any decrease in the total operating revenues or net income of the Operating Partnership as compared with the amounts shown in the most recent consolidated balance sheets of the Operating Partnership and the Guarantors included in the Registration Statement or incorporated by reference therein, or, during the period from the date of the most recent consolidated statement of operations included in the Registration Statement or incorporated by reference therein to a specified date not more than three business days prior to the date of the applicable Terms Agreement, there were any decreases, as compared with the corresponding period in the preceding year, in revenues, net income or funds from operations of the Operating Partnership or the Guarantors except in all instances for changes, increases or decreases which the Registration Statement and the Prospectus disclose have occurred or may occur; and (iv) in addition to the audit referred to in their opinions and the limited procedures referred to in clause (iii) above, they have carried out certain specified procedures, not constituting an audit, with respect to certain amounts, percentages and financial information which are included in the Registration Statement and Prospectus and which are specified by the Representatives, and have found such amounts, percentages and financial information to be in agreement with the relevant accounting, financial and other records of the Operating Partnership and the Guarantors identified in such letter.

(e) At Closing Time, the Representatives shall have received from KPMG LLP a letter, dated the Closing Time, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (d) of this Section, except that the “specified date” referred to shall be a date not more than three business days prior to Closing Time.

(f) At Closing Time, the Underwritten Securities shall be rated investment grade by one or more nationally recognized statistical rating organizations and the Operating Partnership shall have delivered to the Representatives a letter, dated the Closing Time, from each such rating organization, or other evidence satisfactory to the Representatives, confirming that such Underwritten Securities have such ratings; and since the date of this Agreement, there shall not have occurred a downgrading in the rating assigned to such Underwritten Securities or any of the Operating Partnership’s other debt securities by any nationally recognized securities rating organization, and no such securities rating organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of such Underwritten Securities or any of the Operating Partnership’s other debt securities.

(g) At Closing Time, counsel for the Underwriter shall have been furnished with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the applicable Underwritten Securities as contemplated herein, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Operating Partnership and the Guarantors, if applicable, in connection with the issuance and sale of the applicable Underwritten Securities as herein contemplated shall be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriter.

If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Operating Partnership at any time at or prior to Closing Time and such termination shall be without liability of any party to any other party except as provided in Section 4 hereof.

SECTION 6. Indemnification.

(a) The Operating Partnership will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, Prospectus, preliminary prospectus supplement or Prospectus Supplement, or any amendment or supplement thereto, or arise out of or are 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, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Operating Partnership shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, such preliminary prospectus, preliminary prospectus supplement or the Prospectus or Prospectus Supplement, or any such amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Operating Partnership by any Underwriter through the Representatives expressly for use under the caption “Plan of Distribution” or “Underwriting” in the Registration Statement (or any amendment thereto) or such preliminary prospectus, preliminary prospectus supplement or the Prospectus or Prospectus Supplement (or any amendment or supplement thereto).

(b) Each Underwriter will indemnify and hold harmless the Operating Partnership against any losses, claims, damages or liabilities to which the Operating Partnership may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, Prospectus, preliminary prospectus supplement or Prospectus Supplement, or any amendment or supplement thereto, or arise out of or are 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 preliminary prospectus, Prospectus, preliminary prospectus supplement or Prospectus Supplement, or any such amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Operating Partnership by such Underwriter through the Representatives expressly for use under the caption “Plan of Distribution” or “Underwriting” in the Registration Statement (or any amendment thereto) or such preliminary prospectus, preliminary prospectus supplement or the Prospectus or Prospectus Supplement (or any amendment or supplement thereto); and will reimburse the Operating Partnership for any legal or other expenses reasonably incurred by the Operating Partnership in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying 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 shall not be liable to such indemnified party under this Section 6 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) representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel 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. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action 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) If the indemnification provided for in this Section 6 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Operating Partnership on the one hand and the Underwriters on the other from the offering of the Underwritten Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Operating Partnership on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Operating Partnership on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the Underwritten Securities (before deducting expenses) received by the Operating Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Operating Partnership and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) 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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Underwritten Securities underwritten by it pursuant to the applicable Terms Agreement and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Operating Partnership under this Section 6 shall be in addition to any liability which the Operating Partnership may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section 6 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company, as general partner of the Operating Partnership and to each person, if any, who controls the Operating Partnership within the meaning of the 1933 Act.

SECTION 7. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or the applicable Terms Agreement, or contained in certificates of the officers of the Operating Partnership submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any termination of the applicable Terms Agreement, or any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Operating Partnership and shall survive delivery of the Underwritten Securities to the Underwriters.

SECTION 8. Termination of Agreement.

(a) The Representatives may terminate the applicable Terms Agreement, by notice to the Operating Partnership, at any time at or prior to Closing Time (i) if either the Operating Partnership, the Company or the Subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus any loss or interference with their business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus; or (ii) if there has been, since the date of such Terms Agreement or since the respective dates as of which information is given in the Prospectus, any change in the partnership interests or long-term debt of the Operating Partnership or the Subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, unitholders’ or stockholders’ equity or results of operations of the Operating Partnership, the Company or the Subsidiaries, otherwise than as set forth or contemplated in the Prospectus; or (iii) if there has occurred any downgrading in the rating accorded the Operating Partnership’s debt securities by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the 1933 Act, and no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Operating Partnership’s debt securities; or (iv) if there has occurred a suspension or material limitation in trading in securities generally on the New York Stock Exchange or on the American Stock Exchange or a suspension or material limitation in trading in the Company’s or Operating Partnership’s securities on the New York Stock Exchange, or if a general moratorium on commercial banking activities has been declared by either Federal, New York, Delaware or Maryland authorities or if there has occurred a material disruption in commercial banking or securities settlement or clearance services in the United States; or (v) if there has occurred any outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (vi) if there has occurred any other calamity or crisis in the United States or elsewhere resulting in material disruption in the U.S. financial markets, if the effect of any such event specified in Clause (i), (ii), (v) or (vi) of this Section 8(a) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Underwritten Securities on the terms and in the manner contemplated in the Prospectus. As used in this Section 8(a), the term “Prospectus” means the Prospectus together with any Prospectus Supplement in the form first used to confirm sales of the Underwritten Securities.

(b) In the event of any such termination, in respect to such terminated Terms Agreement, (x) the covenants set forth in Section 3 with respect to any offering of Underwritten Securities shall remain in effect so long as any Underwriter owns any such Underwritten Securities purchased from the Operating Partnership pursuant to the applicable Terms Agreement and (y) the covenant set forth in Section 3(i) hereof, the provisions of Section 4 hereof, the indemnity and contribution agreements set forth in Section 6 hereof, and the provisions of Sections 7 and 12 hereof shall remain in effect.

SECTION 9. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time to purchase the Underwritten Securities which it or they are obligated to purchase under the applicable Terms Agreement (the “Defaulted Securities”), the Representatives 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 Representatives 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 Underwritten Securities to be purchased pursuant to such Terms Agreement, each of the non-defaulting Underwriters named in such Terms Agreement shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

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

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default under this Agreement and the applicable Terms Agreement.

In the event of any such default which does not result in a termination of the applicable Terms Agreement, each of the Representatives or the Operating Partnership shall have the right to postpone Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.

SECTION 10. 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.

SECTION 11. Parties. This Agreement and the applicable Terms Agreement shall each inure to the benefit of and be binding upon the parties hereto and their respective successors. Nothing expressed or mentioned in this Agreement or the applicable Terms Agreement is intended or shall be construed to give any person, firm or corporation, other than those referred to in Section 6 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or the applicable Terms Agreement or any provision herein or therein contained. This Agreement and the applicable Terms Agreement and all conditions and provisions hereof and thereof are intended to be for the sole and exclusive benefit of the parties hereto and thereto and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Underwritten Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 12. Governing Law and Time. This Agreement and the Terms 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.
