Ladies and Gentlemen:

     Kilroy Realty Corporation, a Maryland corporation (the  "Company"), and
Kilroy Realty, L.P., a Delaware limited partnership (the "Operating
Partnership"), each hereby confirms its agreement (this "Agreement") with
Prudential Securities Incorporated (the "Underwriter"), as set forth below.

     1.   Securities.  Subject to the terms and conditions herein contained, the
          ----------                                                            
Company proposes to issue and sell to the Underwriter an aggregate of 724,888
shares (the "Securities") of the Company's common stock, par value $.01 per
share (the "Common Stock").  The Underwriter intends to deposit the Securities
with the trustee of the National Equity Trust Equity Portfolio Series 2 (REIT
Portfolio), a registered unit investment trust under the Investment Company Act
of 1940, as amended (the "Trust"), to which Prudential Securities Incorporated
acts as sponsor and depositor in exchange for units in the Trust.

     2.   Representations and Warranties of the Company and the Operating
          ---------------------------------------------------------------
Partnership.  The Company and the Operating Partnership, jointly and severally,
- -----------                                                                    
represent and warrant to, and agree with, the Underwriter that:

          (a) The Company meets the requirements for use of Form S-3 under the
     Securities Act of 1933, as amended (the "Act").  A registration statement
     on such Form S-3 (File No. 333-45097) with respect to the Securities,
     including a basic prospectus, has been filed by the Company with the
     Securities and Exchange Commission (the "Commission") under the Act, and
     one or more amendments to such registration statement may have been so
     filed.  Such registration statement, as so amended, has been declared by
     the Commission to be effective under the Act.  Such registration statement,
     as amended at the date of this Agreement, meets the requirements set forth
     in Rule 415(a)(1)(x) under the Act and complies in all other material
     respects with said Rule.  The Company will next file with the Commission
     either (A) if the Company relies on Rule 434 under the Act, a Term Sheet
     (as hereinafter defined) relating to the Securities that shall identify the
     Preliminary Prospectus (as hereinafter defined) that it supplements and, if
     required to be filed pursuant to Rules 434(c)(2) and 424(b), an Integrated
     Prospectus (as hereinafter defined), in either case, containing such
     information as is required or permitted by Rules 434, 430A and 424(b) under
     the Act or (B) if the Company does not rely on Rule 434 under the Act,
     pursuant to Rule 424(b) under the Act a final prospectus supplement to the
     basic prospectus included in such registration statement, as so amended,
     describing the Securities and the offering thereof, in such form as has
     been provided to, or discussed with, and approved by the Underwriter as
     provided in Section 5(a) of this Agreement. The Company may also file a
     related registration statement with the Commission pursuant to Rule 462(b)
     under the Act for the purpose of registering certain additional Securities,
     which registration, assuming compliance with 
<PAGE>
 
     the requirements of Rule 462(b), shall be effective upon filing with the
     Commission. As used in this Agreement, the term "Registration Statement"
     means the registration statement initially filed relating to the
     Securities, as amended at the time when it was declared effective,
     including (i) all financial schedules and exhibits thereto, (ii) all
     documents incorporated by reference or deemed to be incorporated by
     reference therein, (iii) any information omitted therefrom pursuant to Rule
     430A under the Act and included in the Prospectus (as hereinafter defined)
     or, if required to be filed pursuant to Rule 434(c)(2) and 424(b) under the
     Act, in the Integrated Prospectus, (iv) and any Rule 462(b) Registration
     Statement (as hereinafter defined); the term "Rule 462(b) Registration
     Statement" means any registration statement filed with the Commission
     pursuant to Rule 462(b) under the Act; the term "Basic Prospectus" means
     the prospectus included in the Registration Statement as amended by any
     form of prospectus filed thereafter pursuant to Rule 424; the term
     "Preliminary Prospectus" means any preliminary form of the Prospectus (as
     hereinafter defined), if any, specifically relating to the Securities, in
     the form first filed with, or transmitted for filing to, the Commission
     pursuant to Rule 424 under the Act; the term "Prospectus Supplement" means
     any prospectus supplement specifically relating to the Securities, in the
     form first filed with, or transmitted for filing to, the Commission
     pursuant to Rule 424 under the Act; the term "Prospectus" means (A) if the
     Company relies on Rule 434 under the Act, the Term Sheet relating to the
     Securities that is first filed pursuant to Rule 424(b)(7) under the Act,
     together with the Preliminary Prospectus identified therein that such Term
     Sheet supplements; (B) if the Company does not rely on Rule 434 under the
     Act, the Preliminary Prospectus; or (C) if the Company does not rely on
     Rule 434 under the Act and if no Preliminary Prospectus is required to be
     filed, the Basic Prospectus, including, in each case, the Prospectus
     Supplement; "Basic Prospectus," "Prospectus," "Preliminary Prospectus" and
     "Prospectus Supplement" shall include in each case the documents, if any,
     filed by the Company with the Commission pursuant to Securities Exchange
     Act of 1934, as amended (the "Exchange Act"), and incorporated by reference
     therein; the term "Integrated Prospectus" means a prospectus first filed
     with the Commission pursuant to Rules 434(c)(2) and 424(b) under the Act;
     and the term "Term Sheet" means any abbreviated term sheet that satisfies
     the requirements of Rule 434 under the Act. Any reference in this Agreement
     to an "amendment" or "supplement" to any Preliminary Prospectus, the
     Prospectus, or any Integrated Prospectus or an "amendment" to any
     registration statement (including the Registration Statement) shall be
     deemed to include any document incorporated by reference therein that is
     filed with the Commission under the Exchange Act after the date of such
     Preliminary Prospectus, Prospectus, Integrated Prospectus or registration
     statement, as the case may be. For purposes of the preceding sentence, any
     reference to the "effective date" of an amendment to a registration
     statement shall, if such amendment is effected by means of the filing with
     the Commission under the Exchange Act of a document incorporated by
     reference in such registration statement, be deemed to refer to the date on
     which such document was so filed with the Commission; any reference herein
     to the "date" of a Prospectus that includes a Term Sheet shall mean the
     date of such Term Sheet.

          (b) The Commission has not issued any order preventing or suspending
     the use of any Preliminary Prospectus.  When any Preliminary Prospectus and
     any amendment or supplement thereto was filed with the Commission, it (i)
     contained all statements required to be stated therein in accordance with,
     and complied in all material respects with the requirements of, the Act,
     the Exchange Act and the respective rules and regulations of the Commission
     thereunder, and (ii) did not 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, not misleading.  When the Registration Statement or any amendment
     thereto was declared effective, it (i) contained all statements required to
     be stated therein in accordance with, and complied in all material respects
     with the requirements of, the Act, the Exchange Act and the respective
     rules and regulations of the Commission thereunder and (ii) did not include
     any untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein not misleading. When the
     Registration Statement or any amendment thereto was or is declared
     effective, it (i) contained or will contain all statements required to be
     stated therein in accordance with, and complied or will comply in all

                                       2
<PAGE>
 
     material respects with the requirements of, the Act, the Exchange Act and
     the respective rules and regulations of the Commission thereunder and (ii)
     did not or will not include any untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein not
     misleading.  When the Prospectus or any Term Sheet that is a part thereof
     or any Integrated Prospectus or any amendment or supplement to the
     Prospectus is filed with the Commission pursuant to Rule 424(b) (or, if the
     Prospectus or part thereof or such amendment or supplement is not required
     to be so filed, when the Registration Statement or the amendment thereto
     containing such amendment or supplement to the Prospectus was or is
     declared effective), on the date when the Prospectus is otherwise amended
     or supplemented and on the Closing Date (as hereinafter defined), each of
     the Prospectus, and, if required to be filed pursuant to Rules 434(c)(2)
     and 424(b) under the Act, the Integrated Prospectus as amended or
     supplemented at any such time, (i) contained or will contain all statements
     required to be stated therein in accordance with, and complied or will
     comply in all material respects with the requirements of, the Act, the
     Exchange Act and the respective rules and regulations of the Commission
     thereunder and (ii) did not or will not 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, not misleading. The foregoing provisions of this paragraph (b)
     do not apply to statements or omissions made in any Preliminary Prospectus
     or any amendment or supplement thereto, the Registration Statement or any
     amendment thereto, the Prospectus or, if required to be filed pursuant to
     Rules 434(c)(2) and 424(b) under the Act, the Integrated Prospectus or any
     amendment or supplement thereto, in reliance upon and in conformity with
     written information furnished to the Company by the Underwriter as set
     forth in Section 11 hereof.

          (c) If the Company has elected to rely on Rule 462(b) and the Rule
     462(b) Registration Statement has not been declared effective, (i) the
     Company has filed a Rule 462(b) Registration Statement in compliance with
     and that, assuming compliance with Rule 462(b), is effective upon filing
     with the Commission and has received confirmation of its receipt and (ii)
     the Company has given irrevocable instructions for transmission of the
     applicable filing fee in connection with the filing of the Rule 462(b)
     Registration Statement, in compliance with Rule 111 promulgated under the
     Act or the Commission has received payment of such filing fee.

          (d) The Company and each of its subsidiaries that are corporations
     have been duly organized and are validly existing as corporations in good
     standing under the laws of their respective jurisdictions of incorporation
     and are duly qualified to transact business as foreign corporations and are
     in good standing under the laws of all other jurisdictions where the
     ownership or leasing of their respective properties or the conduct of their
     respective businesses requires such qualification, except where the failure
     to be so qualified does not amount to a material liability or disability to
     the Company and its subsidiaries, taken as a whole.  Each of the Company's
     subsidiaries that are partnerships have been duly organized and are validly
     existing as partnerships in good standing under the laws of their
     respective jurisdictions of organization and, as applicable, are duly
     qualified to transact business as foreign partnerships and are in good
     standing under the laws of all other jurisdictions where the ownership or
     leasing of their respective properties or the conduct of their respective
     businesses requires such qualification, except where the failure to be so
     qualified does not amount to a material liability or disability to the
     Company and its subsidiaries, taken as a whole.

          (e) The Company and each of its subsidiaries have full power
     (corporate or other) to own or lease their respective properties and
     conduct their respective businesses as described in the Registration
     Statement and each of the Prospectus and any Integrated Prospectus or, if

     The partnership agreements of the Company's subsidiaries that are

     a foreign limited partnership and is in good standing under the laws of all
     other jurisdictions where the ownership or leasing of its properties or the
     conduct of its business requires such qualification, except where the

     issued in connection with the offering of securities contemplated hereby
     have been duly authorized for issuance by the Operating Partnership to the

     designed to cause or to result in, or that has constituted or which might
     reasonably be expected to constitute, the stabilization or manipulation of

     comprising part of the Properties, in each case free and clear of any
     security interests, liens, encumbrances, equities, claims and other

     such property and do not interfere with the use made or proposed to be made
     of such property by the Company or such subsidiary, and any real property
     and buildings comprising part of the Properties held pursuant to or subject
     to a ground lease, air space lease or other lease will be held by the
     Company or any such subsidiary under or subject to valid, subsisting and

     subsidiary, in each case except as described in or contemplated by the
     Prospectus and any Integrated Prospectus (or, if the Prospectus or any

     Preliminary Prospectus).

          (x)  No labor dispute with the employees of the Company or any of its
     subsidiaries exists or, to the knowledge of the Company or any of its

<PAGE>
 
     material adverse change in the condition (financial or otherwise), business
     prospects, net worth or results of operations of the Company and its

     the Prospectus and any Integrated Prospectus (or, if the Prospectus or any
     required Integrated Prospectus is not in existence, the most recent
     Preliminary Prospectus).

          (y)  The Company and each of its subsidiaries own or possess all
     contract rights that are material to the businesses now operated or
     proposed to be operated by them taken as a whole as described in the
     Prospectus and any Integrated Prospectus (or, if the Prospectus or any
     required Integrated Prospectus is not in existence, the most recent
     Preliminary Prospectus), including all such contract rights referred to in
     the Prospectus.  All such contracts are in full force and effect, and
     neither the Company nor any such subsidiary is aware of any material breach
     by any party under any of such contracts.

          (z)  The Company and each of its subsidiaries are 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 as described in the Prospectus and any Integrated Prospectus
     (or, if the Prospectus or any required Integrated Prospectus is not in
     existence, the most recent Preliminary Prospectus); and neither the Company
     nor any such subsidiary has any reason to believe that it will not be able
     to renew such insurance coverage as and when such coverage expires or to
     obtain similar coverage from similar insurers as may be necessary to
     continue its business at a cost that would not materially and adversely
     affect the condition (financial or otherwise), business prospects, net
     worth or results of operations of the Company and its subsidiaries, taken
     as a whole, except as described in or contemplated by the Prospectus and
     any Integrated Prospectus (or, if the Prospectus or any required Integrated
     Prospectus is not in existence, the most recent Preliminary Prospectus).

     distribution on such subsidiary's capital stock or partnership interests,
     from repaying to the Company any loans or advances to such subsidiary from
     the Company or from transferring any of such subsidiary's property or
     assets to the Company or any other subsidiary of the Company, except as
     described in or contemplated by the Prospectus and any Integrated
     Prospectus (or, if the Prospectus or any required Integrated Prospectus is
     not in existence, the most recent Preliminary Prospectus) and except
     pursuant to (i) the mortgage loans and credit facility, descriptions of
     which are set forth or incorporated by reference in the Registration
     Statement, the Prospectus and any Integrated Prospectus, or, if the
     Prospectus or any required Integrated Prospectus is not in existence, the
     most recent Preliminary Prospectus), (ii) the terms and conditions of the
     Operating Partnership's 8.075% Series A Cumulative Redeemable Units, (iii)

     transferring any of such subsidiary's property or assets to the Company or
     any other subsidiary of the Company, (A) customary non-assignment
     provisions contained in leases to which the Company or any of its
     subsidiaries is a party and (B) security interests, including purchase
     money obligations, applicable to any property of the Company or any of its

          (bb) The Company and its subsidiaries possess all certificates,
     authorizations and permits issued by the appropriate federal, state or
     foreign regulatory authorities necessary to conduct their respective
     businesses, and neither the Company nor any such subsidiary has received
     any notice of proceedings relating to the revocation or modification of any
     such certificate, authorization or permit which, singly or in the
     aggregate, if the subject of any unfavorable decision, ruling or finding,
     would result in a material adverse change in the condition (financial or
     otherwise), business prospects, net worth or results of operations of the
     Company and its subsidiaries, taken as a whole, except as described in or
     contemplated by the Prospectus and any Integrated Prospectus (or, if the
     Prospectus or any required Integrated Prospectus is not in existence, the
     most recent Preliminary Prospectus).

          (cc) The Company is not, and as of the Closing Date will not be,
     subject to registration as an investment company under the Investment
     Company Act of 1940, as amended.

          (dd) Each of the Company and its subsidiaries has filed all foreign,
     federal, state and local tax returns that are required to be filed or has
     requested extensions thereof (except in any case in which the failure so to
     file would not have a material adverse effect on the Company and its
     subsidiaries, taken as a whole) and has paid all taxes required to be paid
     by it and any other assessment, fine or penalty levied against it, to the
     extent that any of the foregoing is due and payable, except for any such
     assessment, fine or penalty that is currently being contested in good faith
     and for which a reserve has been established or as described in or
     contemplated by the Prospectus and any Integrated Prospectus (or, if the
     Prospectus or any required Integrated Prospectus is not in existence, the
     most recent Preliminary Prospectus).  All of such returns are true, correct
     and complete.  No audit, inquiry, investigation or similar proceeding is
     currently pending or, to the knowledge of the Company, threatened against
     the Company or any of its assets with respect to which it may be liable for
     the payment of taxes, an adverse outcome of which would reasonably be
     expected to result in a material adverse effect.

          (ee) Neither the Company nor any of its subsidiaries is in violation
     of any applicable federal or state law or regulation relating to
     occupational safety and health, the storage, handling or transportation of
     hazardous or toxic materials, pollution or otherwise relating to protection
     of the environment, and the Company and its subsidiaries have received all
     permits, licenses or other approvals required of them under applicable
     federal and state occupational safety and health and environmental laws and
     regulations to conduct their respective businesses or the businesses
     proposed to be conducted by them as described in the Prospectus and any
     Integrated Prospectus (or, if the Prospectus or any required Integrated
     Prospectus is not in existence, the most recent Preliminary Prospectus),
     and the Company and each such subsidiary is in compliance with all terms
     and conditions of any such permit, license or approval, except any such
     violation of law or regulation, failure to receive required permits,
     licenses or other approvals or failure to comply with the terms and
     conditions of such permits, licenses or approvals which would not, singly
     or in the aggregate, result in a material adverse change in the condition
     (financial or otherwise), business prospects, net worth or results of
     operations of the Company and its subsidiaries, taken as a whole, except as
     described in or contemplated by the Prospectus and any Integrated
     Prospectus (or, if the Prospectus or any required Integrated Prospectus is
     not in existence, the most recent Preliminary Prospectus).

          (ff) Each certificate signed by any officer of the Company and
     delivered to the Underwriter or counsel for the Underwriter on the Closing
     Date shall be deemed to be a representation and warranty by the Company to
     the Underwriter as to the matters covered thereby.

          (gg) Except as described in or contemplated by the Prospectus and any
     Integrated Prospectus (or, if the Prospectus or any required Integrated
     Prospectus is not in existence, the most recent Preliminary Prospectus),
     neither the Company nor any such subsidiary owns any shares of stock or any
     other equity securities of any corporation or has any equity interest in
     any firm, partnership, association or other entity.

          (hh)  The Company and each of its subsidiaries maintain a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded accountability for assets
     is compared with the existing assets at reasonable intervals and
     appropriate action is taken with respect to any differences.

                                       9

          (ii) No default exists, and no event has occurred which, with notice
     or lapse of time or both, would constitute a default in the due performance
     and observance of any term, covenant or condition of any indenture,
     mortgage, deed of trust, lease or other agreement or instrument to which
     the Company or any of its subsidiaries is a party or by which the Company
     or any of its subsidiaries or any of their respective properties is bound
     or may be affected in any material adverse respect with regard to property,
     business or operations of the Company and its subsidiaries taken as a
     whole.

          (jj) Except as otherwise disclosed in the Prospectus and any
     Integrated Prospectus (or, if the Prospectus or any required Integrated
     Prospectus is not in existence, the most recent Preliminary Prospectus),
     since January 1, 1990 no foreclosures have been instituted and none are
     currently threatened with respect to any property or assets directly or
     indirectly owned (whether now or in the past) by the Kilroy Group or the
     Company or any of its subsidiaries.

          (kk) (i) To the knowledge of the Company or any of its subsidiaries,
     no proceeding or filing of a petition seeking relief under Title 11 of the
     United States Code or any other federal, state or foreign bankruptcy,
     insolvency, liquidation or similar law has been commenced or instituted
     (whether voluntary or involuntary) by or with respect to any member of the
     Kilroy Group, (ii) no member of the Kilroy Group has applied for or
     consented to the appointment of a receiver, trustee, custodian,
     sequestrator or similar official for any such persons or for a substantial
     part of any such persons' property or assets and (iii) no member of the
     Kilroy Group has made a general assignment for the benefit of its
     creditors.

          (ll) No relationship, direct or indirect, exists between or among the
     Company or the Operating Partnership on the one hand, and the directors,
     officers, stockholders (in the case of the Company), limited partners (in
     the case of the Operating Partnership), tenants, customers or suppliers of
     the Company or the Operating Partnership on the other hand, which is
     required to be described in the Prospectus and any Integrated Prospectus
     (or, if the Prospectus or any required Integrated Prospectus is not in
     existence, the most recent Preliminary Prospectus) which is not so
     described.

          (mm) The Company has been and is organized and operated in conformity
     with the requirements for qualification as a real estate investment trust
     (a "REIT") under the Internal Revenue Code of 1986, as amended (the
     "Code"), and will have no earnings and profits accumulated in a non-REIT
     year within the meaning of Section 857(a)(3)(B) of the Code, and the actual
     method of operation of the Company and its subsidiaries has enabled, and
     its proposed method of operation will enable, the Company to meet the
     requirements for taxation as a REIT under the Code beginning with its
     taxable year ending December 31, 1997 and for its subsequent taxable years.
     The Company will elect to be taxed as a REIT under the Code beginning with
     its taxable year ending December 31, 1997.  All statements in the
     Prospectus and any Integrated Prospectus (or, if the Prospectus or any
     required Integrated Prospectus is not in existence, the most recent
     Preliminary Prospectus) regarding the Company's qualification as a REIT are
     true, complete and correct in all material respects.

          (nn) (i) Each of the Properties (including, for purposes of this
     paragraph, each of the properties that the Company or any of its
     subsidiaries has the option to purchase) complies with all applicable
     codes, laws, ordinances and regulations (including, without limitation,
     building and zoning codes and laws and regulations relating to access to
     the Properties) and deed restrictions or other covenants, except for such
     failures to comply that would not materially impair the value of any of the
     Properties and would not result in a forfeiture or reversion of title; (ii)
     neither the Company nor any of its subsidiaries has knowledge of any
     pending or threatened litigation, moratorium, condemnation proceedings,
     zoning change, or other similar proceeding or action that could in any
     manner affect the size of, use of, improvements on, construction on, access
     to or availability of utilities or other necessary services to, the
     Properties, except such proceedings or actions which are not reasonably
     expected to, singly or in the aggregate, result in a material adverse
     change in the condition (financial or otherwise), business prospects, net
     worth or results of operations of the Company and its 

                                       10

     subsidiaries, taken as a whole; (iii) all liens, charges, encumbrances,
     claims, or restrictions on or affecting the properties and assets
     (including the Properties) of the Company or any of its subsidiaries that
     (A) would result in a material adverse change in the condition (financial
     or otherwise), business prospects, net worth or results of operations of
     the Company and its subsidiaries, taken as a whole, except as described in
     or contemplated by the Prospectus and any Integrated Prospectus (or, if the
     Prospectus or any required Integrated Prospectus is not in existence, the
     most recent Preliminary Prospectus) or (B) are required to be disclosed in
     the Prospectus and any Integrated Prospectus (or, if the Prospectus or any
     required Integrated Prospectus is not in existence, the most recent
     Preliminary Prospectus) are disclosed therein; (iv) neither the Company,
     any of its subsidiaries nor any tenant of any portion of any of the
     Properties is in default under any of the ground leases or air space leases

     other occupancy or license agreement relating to, or under any of the
     mortgages or other security documents or other agreements encumbering or
     otherwise recorded against, the Properties and there is no event which, but
     for the passage of time or the giving of notice or both, would constitute a
     default under any of such documents or agreements, except such defaults
     that would not, singly or in the aggregate, result in a material adverse
     change in the condition (financial or otherwise), business prospects, net
     worth or results of operations of the Company and its subsidiaries, taken
     as a whole, except as described in or contemplated by the Prospectus and

     all presently applicable provisions of the Americans with Disabilities Act

     presently applicable provisions of the Americans with Disabilities Act
     would result in a material adverse change in the condition (financial or
     otherwise), business prospects, net worth or results of operations of the
     Company and its subsidiaries, taken as a whole.

          (pp) Except as otherwise disclosed in the Prospectus and any

     of the Company, any other owners of the Properties (including, for purposes
     of this paragraph, each of the properties that the Company or any of its

     3.   Purchase Sale and Delivery of the Securities.
          -------------------------------------------- 

          (a) On the basis of the representations, warranties, agreements and
     covenants herein contained and subject to the terms and conditions herein
     set forth, the Company agrees to issue and sell to the Underwriter, and the
     Underwriter agrees, to purchase from the Company, at a purchase price of
     $26.13 per share, the Securities.  One or more certificates in definitive
     form for the Securities that the Underwriter has agreed to purchase
     hereunder, and in such denomination or denominations and registered in such
     name or names as the Underwriter requests upon notice to the Company at
     least 48 hours prior to the Closing Date, shall be delivered by or on
     behalf of the Company to the Underwriter, against payment by or on behalf
     of the Underwriter of the purchase price therefor by wire transfer in same-
     day funds (the "Wired Funds") to the account of the Company.  Such delivery
     of and payment for the Securities shall be made at the offices of Skadden,
     Arps, Slate, Meagher & Flom LLP, 300 South Grand Avenue, Suite 3400, Los
     Angeles, California 90071 at 6:30 A.M., local time, on February 18, 1998,
     or at such other place, time or date as the Underwriter and the Company may
     agree upon, such time and date of delivery against payment being herein
     referred to as the "Closing Date."  The Company will make such certificate
     or certificates for the Securities available for checking and packaging by
     the Underwriter at the offices in New York, New York of the Company's
     transfer agent or registrar or of the Underwriter at least 24 hours prior
     to the Closing Date.

          (b) The Company hereby acknowledges that the wire transfer by or on
     behalf of the Underwriter of the purchase price for any Securities does not
     constitute closing of a purchase and sale of the Securities.  Only
     execution and delivery of a receipt for Securities by the Underwriter
     indicates completion of the closing of a purchase of the Securities from
     the Company.  Furthermore, in the event that the Underwriter wires funds to
     the Company prior to the completion of the closing of a purchase of
     Securities, the Company hereby acknowledges that until the Underwriter
     executes and delivers a receipt for the Securities, by facsimile or
     otherwise, the Company will not be entitled to the Wired Funds and shall
     return the Wired Funds to the Underwriter as soon as practicable (by wire
     transfer of same-day funds) upon demand.  In the event that the closing of
     a purchase of Securities is not completed and the Wired Funds are not
     returned by the Company to the Underwriter on the same day the Wired Funds
     were received by the Company, the Company agrees to pay to the Underwriter,
     in respect of each day the Wired Funds are not returned by it, in same-day
     funds, interest on the amount of such Wired Funds in an amount representing
     the Underwriter's cost of financing as reasonably determined by the
     Underwriter.

     4.   Offering by the Underwriter. Upon the Underwriter's authorization of
          ---------------------------                                         
the release of the Securities, the Underwriter proposes to deposit the
Securities with the trustee of the Trust, for which Prudential Securities
Incorporated acts as a sponsor and depositor, in exchange for units in the
Trust, in accordance with the terms of the Prospectus.

     5.   Covenants of the Company.  Each of the Company and the Operating
          ------------------------                                        
Partnership covenants and agrees with the Underwriter that:

          (a) The Company will use its best efforts to cause the Registration
     Statement, if not effective at the time of execution of this Agreement, and
     any amendments thereto to become effective as promptly as possible.  If
     required, the Company will file the Prospectus or any Term Sheet that
     constitutes a part thereof, any Integrated Prospectus, Prospectus
     Supplement, as the case may be, and any amendment or supplement thereto
     with the Commission in the manner and within the time period required by
     Rules 434 and 424(b) under the Act.  During any time when a prospectus
     relating to the Securities is required to be delivered under the Act, the
     Company (i) will comply with all requirements imposed upon it by the Act
     and the Exchange Act and the respective rules and regulations of the
     Commission thereunder to the extent necessary to permit the continuance of
     sales of or dealings in the Securities in accordance with the provisions
     hereof and of the Prospectus and any Integrated Prospectus, as then amended
     or supplemented, and (ii) will not file with the Commission the Prospectus,
     Term Sheet any Integrated Prospectus or any amendment or supplement thereto
     or any amendment to the Registration Statement or any Rule 462(b)
     Registration Statement of which the Underwriter shall not previously have
     been advised and furnished with a copy for a reasonable period of time
     prior to the proposed filing and as to which filing the Underwriter shall
     not have given its consent.  The Company will prepare and file with the
     Commission, in accordance with the rules and regulations of the Commission,
     promptly upon request by the Underwriter or counsel for the Underwriter,
     any amendments to the Registration Statement or amendments or supplements
     to the Prospectus and any Integrated Prospectus that may be necessary or
     advisable in connection with the distribution of the Securities by the
     Underwriter, and will use its best efforts to cause any such amendment to
     the Registration Statement to be declared effective by the Commission as
     promptly as possible.  The Company will advise the Underwriter, promptly
     after receiving notice thereof, of the time when the Registration Statement
     or any amendment thereto has been filed or declared effective or the
     Prospectus, any Integrated Prospectus or any amendment or supplement
     thereto has been filed and will provide evidence satisfactory to the
     Underwriter of each such filing or effectiveness.

          (b) The Company will advise the Underwriter, promptly after receiving
     notice or obtaining knowledge thereof, of (i) the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or any Rule 462(b) Registration Statement or any
     post-effective amendment thereto or any order directed at any document
     incorporated by reference in the Registration Statement, the Prospectus or
     any Integrated Prospectus or any order preventing or suspending the use of
     any Preliminary Prospectus, the Prospectus and any Integrated Prospectus or
     any amendment or supplement thereto, (ii) the suspension of the
     qualification of the Securities for offering or sale in any jurisdiction,
     (iii) the institution, threatening or contemplation of any proceeding for
     any such purpose or (iv) any request made by the Commission for amending
     the Registration Statement or any Rule 462(b) Registration Statement, for
     amending or supplementing any Preliminary Prospectus or the Prospectus and
     any Integrated Prospectus or for additional information.  The Company will
     use its best efforts to prevent the issuance of any such stop order and, if
     any such stop order is issued, to obtain the withdrawal thereof as promptly
     as possible.

          (c) The Company will arrange for the qualification of the Securities
     for offering and sale under the securities or blue sky laws of such
     jurisdictions as the Underwriter  may designate and will continue such
     qualifications in effect for as long as may be necessary to complete the
     distribution of the Securities;  provided, however, that in connection
     therewith, the Company shall not be required to qualify as a foreign
     corporation or to execute a general consent to service of process in any
     jurisdiction.

          (d) If, at any time prior to the later of (i) the final date when a
     prospectus relating to the Securities is required to be delivered under the
     Act or (ii) the Closing Date, any event occurs as a result of which the
     Prospectus or any Integrated Prospectus, as then amended or supplemented,
     would 

                                       14
<PAGE>
 
     include any 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 under which they were made, not misleading, or if for any
     other reason it is necessary at any time to amend or supplement the
     Prospectus or any Integrated Prospectus to comply with the Act, the
     Exchange Act or the respective rules or regulations of the Commission
     thereunder, the Company will promptly notify the Underwriter thereof and,
     subject to Section 5(a) hereof, will prepare and file with the Commission,
     at the Company's expense, an amendment to the Registration Statement or an
     amendment or supplement to the Prospectus or any Integrated Prospectus that
     corrects such statement or omission or effects such compliance.

          (e) The Company will, without charge, provide (i) to the Underwriter
     and to counsel for the Underwriter a conformed copy of the registration
     statement originally filed with respect to the Securities and each
     amendment thereto (in each case including exhibits thereto) or any Rule
     462(b) Registration Statement, certified by the Secretary or an Assistant
     Secretary of the Company to be true and complete copies thereof as filed
     with the Commission by electronic transmission, (iii) so long as a
     prospectus relating to the Securities is required to be delivered under the
     Act, as many copies of each Preliminary Prospectus, the Prospectus or any
     Integrated Prospectus or any amendment or supplement thereto as the
     Underwriter  may reasonably request.  Without limiting the application of
     clause (ii) of the preceding sentence, the Company, not later than (A) 6:00
     p.m., New York City time, on the date of determination of the public
     offering price, if such determination occurred at or prior to 10:00 a.m.,
     New York City time, on such date or (B) 2:00 p.m., New York City time, on
     the business day following the date of determination of the public offering
     price, if such determination occurred after 10:00 a.m., New York City time,
     on such date, will deliver to the Underwriter, without charge, as many
     copies of the Prospectus or any Integrated Prospectus and any amendment or
     supplement thereto as the Underwriter may reasonably request for purposes
     of confirming orders that are expected to settle on the Closing Date.

          (f) The Company, as soon as practicable, will make generally available
     to its securityholders and to the Underwriter a consolidated earnings
     statement of the Company and its subsidiaries that satisfies the provisions
     of Section 11(a) of the Act and Rule 158 thereunder.

          (g) The Company will apply the net proceeds from the sale of the
     Securities as set forth under "Use of Proceeds" in the Prospectus or any
     Integrated Prospectus.

          (h) The Company will not, directly or indirectly, (i) take any action
     designed to cause or to result in, or that has constituted or which might
     reasonably be expected to constitute, the stabilization or manipulation of
     the price of any security of the Company to facilitate the sale or resale
     of the Securities or (ii) (A) sell, bid for, purchase, or pay anyone any
     compensation for soliciting purchases of, the Securities or (B) pay or
     agree to pay to any person any compensation for soliciting another to
     purchase any other securities of the Company.

          (i) If the Company elects to rely on Rule 462(b), the Company shall
     both file a Rule 462(b) Registration Statement with the Commission in
     compliance with Rule 462(b) and pay the applicable fees in accordance with
     Rule 111 promulgated under the Act by the earlier of (i) 10:00 P.M. Eastern
     time on the date of this Agreement and (ii) the time confirmations are sent
     or given, as specified by Rule 462(b)(2).

          (j) The Company will cause the Securities to be duly authorized for
     listing by the New York Stock Exchange prior to the Closing Date, subject
     to official notice of issuance.

          (k) The Company will use its best efforts to continue to meet the
     requirements to qualify as a REIT under the Code.

          (l) The Company will cause the Operating Partnership to operate as a
     limited partnership in accordance with the requirements of Delaware law.

     6.   Expenses.  The Company will pay all costs and expenses incident to the
          --------                                                              
performance of its and the Operating Partnership's obligations under this
Agreement, regardless of whether the transactions contemplated herein are
consummated or this Agreement is terminated pursuant to Section 10 hereof,

Underwriter).  If the sale of the Securities provided for herein is not
consummated because any condition to the obligations of the Underwriter set
forth in Section 7 hereof is not satisfied, because this Agreement is terminated
pursuant to Section 10 hereof or because of any failure, refusal or inability on
the part of the Company or the Operating Partnership to perform all obligations
and satisfy all conditions on its part to be performed or satisfied hereunder
other than by reason of a default by the Underwriter, the Company will reimburse
the Underwriter upon demand for all out-of-pocket expenses (including reasonable

Company shall not in any event be liable to the Underwriter for the loss of

          Kilroy Realty Finance, Inc., a Delaware corporation (the "Finance
          Company"), has been duly incorporated and is validly existing as a

          and is duly qualified to transact business as a foreign corporation

          with the Services Company, the Operating Partnership and the Finance
          Company, the "Subsidiaries"), has been duly organized and is validly

               (ii)  Each of the Operating Partnership, the Finance Company and
          the Finance Partnership have corporate or partnership power (as the
          case may be) to own or lease their respective properties and conduct
          their respective businesses as described in the Registration
          Statement, the Prospectus or any Integrated Prospectus, and the
          Operating Partnership has partnership power to enter into this
          Agreement and to carry out all the terms and provisions thereof to be
          carried out by it.

               (iii) The issued shares of capital stock of the Finance Company
          have been duly authorized and validly issued, are fully paid and
          nonassessable and are owned of record and, to the knowledge of such
          counsel, beneficially by the Company free and clear of any perfected
          security interests or any other security interests, liens,
          encumbrances, equities or claims.  The partnership agreement of the
          Finance Partnership has been duly authorized, executed and delivered
          by the Finance Company, as its general partner, and constitutes the
          valid and binding obligation of the Finance Company, as its general
          partner.  Such partnership agreement reflects the Finance Company as
          the sole general partner of the Finance Partnership and the Operating

               (iv)  All outstanding shares of Common Stock (including the
          Securities, when issued and paid for by the Underwriter in accordance
          with the terms of this Agreement) have been issued in compliance with
          the registration requirements of federal securities laws (or pursuant
          to an exemption therefrom), were not, to the knowledge of such
          counsel, issued in violation of or subject to any agreement to which
          the Company is a party and which is known to such counsel based on a
          certificate of the Company's Chairman of the Board of Directors and
          its President and Chief Executive Officer, or any preemptive rights or
          other rights to subscribe for or purchase any securities; no holders
          of outstanding shares of capital stock of the Company are entitled
          under any agreement to which the Company is a party and which is known
          to such counsel based on a certificate of the Company's Chairman of
          the Board of Directors and its President and Chief Executive Officer,
          as such, to any preemptive or other rights to subscribe for any of the
          Securities; and to the knowledge of such counsel no holders of
          securities of the Company are entitled to have such securities
          registered under the Registration Statement.

               (v)    The outstanding Units, including, without limitation, the
          Units issued to the Company, have been duly authorized and validly
          issued.  The Units to be issued to the Company in exchange for the
          contribution to the Operating Partnership of the net proceeds of the
          offering of the Securities have been duly authorized and, upon
          contribution of the net offering proceeds to the Operating
          Partnership, will be validly issued.  The terms of the Units conform
          in all material respects to the description thereof and all statements
          related thereto contained in the Registration Statement, the
          Prospectus and any Integrated Prospectus.

               (vi)   Except as disclosed in the Registration Statement, the
          Prospectus and any Integrated Prospectus, to the knowledge of such
          counsel there are no outstanding (A) securities, equity interests or
          obligations of the Company or any of its Subsidiaries convertible into
          or exchangeable for any capital stock or equity interests (as the case
          may be) of the Company or any such Subsidiary, (B) warrants, rights or
          options to subscribe for or purchase from the Company or any such
          Subsidiary any such capital stock or equity interests or any such
          convertible or exchangeable securities, equity interests or
          obligations, or (C) obligations of the Company or any such Subsidiary
          to issue any shares of capital stock, equity interests, any such
          convertible or exchangeable securities, equity interests or
          obligations, or any such warrants, rights or options.

               (vii)  The statements set forth under the headings "Partnership
          Agreement of the Operating Partnership," "Certain U.S. Federal Income
          Tax Consequences to Holders of Common Stock," "Federal Income Tax
          Consequences" and "Other Tax Consequences" in the Prospectus and any
          Integrated Prospectus, insofar as such statements describe statutes,
          rules or regulations, legal conclusions with respect to their
          application or provisions of the organizational documents of the
          Company, the Operating Partnership or the Services Company, as
          applicable, have been reviewed by such counsel, are correct in all
          material respects and present fairly the information required to be
          disclosed therein.

               (viii) The execution and delivery of this Agreement have been
          duly authorized by all necessary partnership action of the Operating
          Partnership, and this Agreement has been duly executed and delivered
          by the Operating Partnership, and is the valid and binding agreement
          of the Operating Partnership, enforceable against the Operating
          Partnership in accordance with its terms, subject to the effect of
          bankruptcy, insolvency, moratorium, fraudulent conveyance,
          reorganization and similar laws relating to creditors' rights
          generally, to the application of equitable principles in any
          proceeding, whether at law or in equity, as limited by the
          unenforceability under certain circumstances under law or court
          decisions of provisions providing for the indemnification of or
          contribution to a party with respect to a liability where such
          indemnification or contribution is contrary to public policy and to
          the extent that enforceability of such provisions may be limited due
          to the existence of an untrue statement of a material fact in the
          Registration Statement, the Prospectus and any Integrated Prospectus
          or omission to state a material fact therein necessary to make the
          statements in the Registration Statement, the Prospectus and any
          Integrated Prospectus, respectively, not misleading, it being
          understood that such counsel need not express any view with respect
          thereto other than as set forth in the paragraph immediately following
          clause (xv) below.

               (ix)   To the knowledge of such counsel based on the
          representations of the Company contained herein, review of the letters
          of attorneys delivered to the Company's auditors with respect to the
          existence of contingent liabilities of the Company and a certificate
          of the General Counsel of the Company, (A) no legal or governmental
          proceedings are pending to which the Company or any of the
          Subsidiaries is a party or to which the property of the Company or any
          of the Subsidiaries is subject that are required to be described in
          the Registration Statement or the Prospectus and are not described
          therein, and no such proceedings have been threatened against the
          Company or any of the Subsidiaries or with 

                                       18
<PAGE>
 
          respect to any of their respective properties and (B) no contract or
          other document is required to be disclosed in the Registration
          Statement or the Prospectus or to be filed as an exhibit to the
          Registration Statement that is not disclosed therein or filed as
          required.

               (x)    The issuance, offering and sale of the Securities to the
          Underwriter by the Company pursuant to this Agreement, the compliance
          by the Company and the Operating Partnership with the other provisions
          of this Agreement and the consummation of the other transactions
          herein contemplated do not (A) require the consent, approval,
          authorization, registration or qualification of or with any federal,
          or California or New York governmental authority, except such as have
          been obtained under the Act and such as may be required under state
          securities or blue sky laws, or (B) conflict with or result in a
          breach or violation of any of the terms and provisions of, or
          constitute a default under, any indenture, mortgage, deed of trust,
          lease or other agreement or instrument to which the Company or any of
          the Subsidiaries is a party or by which the Company or any of the
          Subsidiaries or any of their respective properties are bound
          identified by an officer of the Company as material to the Company or
          any of the Subsidiaries (the "Material Agreements"), or the charter
          documents or by-laws or certificate of limited partnership or
          partnership agreement (as the case may be) of the Operating
          Partnership, the Finance Company or the Finance Partnership, or any
          provision of any California or New York statute, rule or regulation
          (other than federal or state securities laws, which are addressed
          elsewhere herein), or court orders specifically directed to the
          Company and identified by an officer of the Company as material to the
          Company or any of the Subsidiaries (the "Court Orders").

               (xi)   The Company is not, and after giving effect to the
          transactions contemplated by this Agreement will not be, subject to
          registration as an investment company under the Investment Company Act
          of 1940, as amended.

               (xii)  The Registration Statement is effective under the Act; any
          required filing of the Prospectus, or any Term Sheet that constitutes
          a part thereof, and any Integrated Prospectus pursuant to Rules 424(b)
          and 434 has been made in the manner and within the time period
          required thereby; and based upon such counsel's due inquiry made to
          the Office of the Secretary of the Commission, no stop order
          suspending the effectiveness of the Registration Statement or any
          post-effective amendment thereto and no order directed at any document
          incorporated by reference in the Registration Statement, the
          Prospectus and any Integrated Prospectus or any amendment or
          supplement thereto has been issued, and no proceedings for that
          purpose have been instituted or threatened or, to the knowledge of
          such counsel, are contemplated by the Commission.

               (xiii) The Registration Statement originally filed with respect
          to the Securities and each amendment thereto and any Rule 462(b)
          Registration Statement, the Prospectus and any Integrated Prospectus
          (in each case, including the documents incorporated by reference
          therein but not including the financial statements, schedules and
          other financial and statistical data contained therein, as to which
          such counsel need express no opinion) comply as to form (at the time
          filed) in all material respects with the applicable requirements of
          the Act, the Exchange Act and the respective rules and regulations of
          the Commission thereunder. The Company meets the requirements for the
          use of Form S-3 under the Act.

               (xiv)  If the Company elects to rely on Rule 434, the Prospectus
          is not "materially different," as such term is used in Rule 434, from
          the prospectus included in the Registration Statement at the time of
          its effectiveness or any post-effective amendment thereto (including
          such information that is permitted to be omitted pursuant to Rule
          430A).

               (xv)  The Company has been and is organized in conformity with
          the requirements for qualification as a "real estate investment trust"
          under the Code, and its method of operation, as described in the
          Registration Statement, the Prospectus and any Integrated Prospectus
          and the Officer's Certificate, has enabled, and its proposed method of
          operation, also as so described, will enable, the Company to meet the
          requirements for qualification and taxation as a "real estate
          investment trust" under the Code beginning with the Company's taxable
          year ended December 31, 1997.

          Such counsel shall also state that they have participated in
     conferences with officers and other representatives of the Company,
     representatives of the independent public accountants for the Company, and
     representatives of the Underwriter, at which the contents of the
     Registration Statement and the Prospectus and any Integrated Prospectus 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 and the Prospectus and any Integrated Prospectus and has not made
     any independent check or verification thereof, during the course of such
     participation no facts came to the attention of such counsel that caused
     such counsel to believe that the Registration Statement, at the time it
     became effective, contained or contains an untrue statement of a material
     fact or omitted or omits to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, or that
     the Prospectus or any Integrated Prospectus, as of its date or as of the
     Closing Date, contained an untrue statement of a material fact or omitted
     to state a material fact necessary to make the statements therein, in light
     of the circumstances under which they were made, not misleading; it being
     understood that such counsel need express no belief with respect to the
     financial statements, schedules and other financial data included or
     incorporated by reference in the Registration Statement or the Prospectus
     or any Integrated Prospectus.

          In rendering any such opinion, such counsel may rely, as to matters of
     fact, to the extent such counsel deems proper, on certificates of
     responsible officers of the Company and public officials and, as to matters
     involving the application of laws of any jurisdiction other than the State
     of California, the State of New York, the Delaware General Corporation Law
     and the Delaware Revised Limited Partnership Act or the United States of
     America on opinions of local, to the extent satisfactory in form and scope
     to counsel for the Underwriter.

          References to the Registration Statement and the Prospectus and any
     Integrated Prospectus in this Section 7(b) shall include any amendment or
     supplement thereto at the date of such opinion.

          (c) The Underwriter shall have received an opinion, dated the Closing
     Date, of Ballard Spahr Andrews & Ingersoll, special Maryland counsel for
     the Company and its subsidiaries, to the following effect:

               (i)   Each of the Company and the Services Company has been duly
          incorporated and is validly existing as a corporation in good standing
          under the laws of the State of Maryland.

               (iv)   The authorized, issued and outstanding capital stock of
          the Company is as set forth or incorporated by reference in the
          Registration Statement and the Prospectus or any Integrated
          Prospectus; all necessary and proper corporate action required under
          the articles of incorporation and bylaws of the Company and the
          Maryland General Corporation Law (the "MGCL") was taken in order to
          duly authorize all outstanding shares of Common Stock (including the
          Securities); all outstanding shares of Common Stock (including the
          Securities, when issued and paid for by the Underwriter in accordance
          with the terms of this Agreement) have been (or in the case of the
          Securities will be) duly and validly issued and fully paid and non-
          assessable, were not, to the best knowledge of such counsel, issued in
          violation of or subject to, under the articles of incorporation or the
          MGCL, any pre-emptive rights or other rights to subscribe for or
          purchase any securities of the Company, and conform, in all material
          respects, to the description thereof contained in the Registration
          Statement and the Prospectus or any Integrated Prospectus; and to the
          best knowledge of such counsel, no holders of outstanding shares of
          capital stock of the Company are entitled, under the articles of
          incorporation or bylaws of the Company or the MGCL, to any pre-emptive
          or other rights to subscribe for any of the Securities.

               (v)    The issued shares of capital stock of the Services Company
          have been duly authorized and validly issued, are fully paid and non-
          assessable and are owned of record and, to the best knowledge of such

          cent ($.01) per share ("Services Company Preferred Stock") .  The
          shares of Services Company Preferred Stock owned by the Operating
          Partnership are, to the best knowledge of such counsel, free and clear
          of any perfected security interests or other liens, encumbrances and
          equitable or other claims.

               (vi)   The execution and delivery by the Company of this
          Agreement in its individual capacity and in its capacity as general
          partner of the Operating Partnership has been duly authorized by all
          necessary corporate action required under the articles of
          incorporation and bylaws of the Company and the MGCL. This Agreement
          has been duly executed and delivered by the Company in its individual
          capacity and in its capacity as general partner of the Operating
          Partnership.

               (vii)  The statements set forth in the Registration Statement and
          the Prospectus or any Integrated Prospectus under the headings
          "Description of Capital Stock" and "Certain Provisions of Maryland Law
          and of the Articles of Incorporation and Bylaws," insofar as such
          statements constitute matters of Maryland corporate law, summaries of
          Maryland corporate legal matters, documents, proceedings or legal
          conclusions under Maryland corporate law, have been reviewed by us and
          are correct in all material respects and present fairly the
          information contained therein.

          Underwriter by the Company pursuant to this Agreement, the compliance
          by the Company with the other provisions of this Agreement and the
          consummation of the other transactions contemplated herein do not: (a)
          require the consent, approval, authorization, registration or
          qualification of or with any Maryland governmental authority; or (b)

          and provisions of the articles of incorporation or the bylaws of the
          Company or the Services Company or any provisions of Maryland law.

          In rendering any such opinion, such counsel may rely, as to matters of
     fact, to the extent such counsel deems proper, on certificates of
     responsible officers of the Company and public officials and, as to matters
     involving the application of laws of any jurisdiction other than the State
     of Maryland on opinions of local, to the extent satisfactory in form and
     scope to counsel for the Underwriter.

          1997, the Acquired Properties and the Pending Acquisitions for the
          year ended December 31, 1996, carrying out certain specified
          procedures (which do not constitute an examination made in accordance
          with generally accepted auditing standards) that would not necessarily
          reveal matters of significance with respect to the comments set forth
          in this paragraph (iii), a reading of the minute books of the
          stockholders, the board of directors and any committees thereof of the
          Company and inquiries of certain officials of the Company who have
          responsibility for financial and accounting matters, nothing came to
          their attention that caused them to believe that:

                    (A) at a specific date (not more than five business days
               prior to the date of such letter), there were any increases in
               debt or decreases in stockholders' equity of the Company or any
               decreases in total assets of the Company, in each case as
               compared with amounts shown in the September 30, 1997 combined
               balance sheet included or incorporated by reference in the
               Registration Statement and the Prospectus, or for the period from
               October 1, 1997 to December 31, 1997, there were any decreases,
               as compared with the corresponding period of the previous year,
               in rental income, total revenues or net income (as applicable) on
               an equivalent property basis, except in all instances for
               changes, increases or decreases which the Registration Statement
               and the Prospectus disclose have occurred or may occur; and

                                       22
<PAGE>
 
                    (B) At a specific date (not more than five business days
               prior to the date of such letter), with respect to the Company,
               there were any increases in borrowings as compared with amounts
               shown in the September 30, 1997 balance sheet included or
               incorporated by reference in the Registration Statement, the
               Prospectus and any Integrated Prospectus, except in all instances
               for changes or increases which the Registration Statement and the
               Prospectus disclose have occurred or may occur.

               (iv)  They have carried out certain specified procedures, not
          constituting an audit, with respect to certain amounts, percentages
          and financial information identified by the Underwriter that are
          derived from the general accounting records of the Company and its
          consolidated subsidiaries and/or their respective predecessors and are
          included in the Registration Statement, the Prospectus and any
          Integrated Prospectus and have compared such amounts, percentages and
          financial information with such records of the Company and its
          consolidated subsidiaries and/or their respective predecessors and
          with information derived from such records and have found them to be
          in agreement, excluding any questions of legal interpretation; and

               (v)   On the basis of a reading of the unaudited pro forma
          condensed consolidated financial statements included in the
          Registration Statement, the Prospectus and any Integrated Prospectus,
          carrying out certain specified procedures that would not necessarily
          reveal matters of significance with respect to the comments set forth
          in this paragraph (v), inquiries of certain officials of the Company
          and its consolidated subsidiaries who have responsibility for
          financial and accounting matters and proving the arithmetic accuracy
          of the application of the pro forma adjustments to the historical
          amounts in the unaudited pro forma condensed consolidated financial
          statements, nothing came to their attention that caused them to
          believe that the unaudited pro forma condensed consolidated financial
          statements do not comply in form in all material respects with the
          applicable accounting requirements of Rule 11-02 of Regulation S-X or
          that the pro forma adjustments have not been properly applied to the
          historical amounts in the compilation of such statements.

          In the event that the letters referred to above set forth any such
     changes, decreases or increases, it shall be a further condition to the
     obligations of the Underwriter that (A) such letters shall be accompanied
     by a written explanation of the Company as to the significance thereof,
     unless the Underwriter deems such explanation unnecessary, and (B) such
     changes, decreases or increases do not, in the sole judgment of the
     Underwriter, make it impractical or inadvisable to proceed with the
     purchase and delivery of the Securities as contemplated by the Registration
     Statement, as amended as of the date hereof.

          References to the Registration Statement and the Prospectus  and any
     Integrated Prospectus in this Section 7(e) with respect to either letter
     referred to above shall include any amendment or supplement thereto at the
     date of such letter.

          (f) the Underwriter shall have received a certificate, dated the
     Closing Date, of the chief executive officer and the principal financial or
     accounting officer of the Company to the effect that:

               (i)   the representations and warranties of the Company and the
          Operating Partnership in this Agreement are true and correct as if
          made on and as of the Closing Date; the Registration Statement, as
          amended as of the Closing Date, does not include any untrue statement
          of a material fact or omit to state any material fact necessary to
          make the statements therein not misleading, and the Prospectus and any
          Integrated Prospectus, as amended or supplemented as of the Closing
          Date, does not 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,
          not misleading; and each of the Company 

                                       23
<PAGE>
 
          and the Operating Partnership has performed all covenants and
          agreements and satisfied all conditions on its part to be performed or
          satisfied at or prior to the Closing Date;

               (ii)  no stop order suspending the effectiveness of the
          Registration Statement or any post-effective amendment thereto and no
          order directed at any document incorporated by reference in the
          Registration Statement or the Prospectus or any amendment or
          supplement thereto has been issued, and no proceedings for that
          purpose have been instituted or threatened or, to the best of the
          Company's or the Operating Partnership's knowledge, are contemplated
          by the Commission;

               (iii) subsequent to the respective dates as of which information
          is given in the Registration Statement and the Prospectus and the
          Integrated Prospectus, neither the Company nor any of its subsidiaries
          has sustained any material loss or interference with their respective
          businesses or properties from fire, flood, hurricane, accident or
          other calamity, regardless of whether covered by insurance, or from
          any labor dispute or any legal or governmental proceeding, and there
          has not been any material adverse change, or any development involving
          a prospective material adverse change, in the condition (financial or
          otherwise), management, business prospects, net worth or results of
          operations of the Company and its subsidiaries, taken as a whole,
          except in each case as described in or contemplated by the
          Registration Statement and the Prospectus and any Integrated
          Prospectus (exclusive of any amendment or supplement thereto); and

               (iv)  all filings required to have been made pursuant to Rule 424
          or Rule 430A under the Act have been made.

          (g) On or before the Closing Date, the Underwriter and counsel for the
     Underwriter shall have received such further certificates, documents or
     other information as they may have reasonably requested from the Company.

          (h) Prior to the commencement of the offering of the Securities, the

     Exchange, subject to official notice of issuance.

     All opinions, certificates, letters and documents delivered pursuant to
this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Underwriter and counsel
for the Underwriter.  The Company shall furnish to the Underwriter such
conformed copies of such opinions, certificates, letters and documents in such
quantities as the Underwriter and counsel for the Underwriter shall reasonably
request.

      8.  Indemnification and Contribution.
          -------------------------------- 

          (a) Each of the Company and the Operating Partnership, jointly and
     severally, agrees to indemnify and hold harmless the Underwriter and each
     person, if any, who controls the Underwriter within the meaning of Section
     15 of the Act or Section 20 of the Exchange Act, against any losses,
     claims, damages or liabilities, joint or several, to which the Underwriter
     or such controlling person may become subject under the Act, the Exchange
     Act or otherwise, insofar as such losses, claims, damages or liabilities
     (or actions in respect thereof) arise out of or are based upon (i) any
     untrue statement or alleged untrue statement made by the Company or the
     Operating Partnership in Section 2 of this Agreement, (ii) any untrue
     statement or alleged untrue statement of any material fact contained in (A)
     the Registration Statement or any amendment thereto, any Preliminary
     Prospectus, the Prospectus and any Integrated Prospectus or any amendment
     or supplement thereto or (B) any application or other document, or any
     amendment or supplement thereto, executed by the Company or based upon
     written information furnished by or on behalf of the Company filed in any
     jurisdiction in order to qualify the Securities under the securities or
     blue sky laws thereof or filed with the 

                                       24
<PAGE>
 
     Commission or any securities association or securities exchange (each an
     "Application") or (iii) the omission or alleged omission to state in the
     Registration Statement or any amendment thereto, any Preliminary
     Prospectus, the Prospectus and any Integrated Prospectus or any amendment
     or supplement thereto, or any Application a material fact required to be
     stated therein or necessary to make the statements therein not misleading,.
     In addition, each of the Company and the Operating Partnership, jointly and
     severally, agrees to reimburse, as incurred, the Underwriter and each such
     controlling person for any legal or other expenses reasonably incurred by
     the Underwriter or such controlling person in connection with
     investigating, defending against or appearing as a third-party witness in
     connection with any such loss, claim, damage, liability or action;
     provided, however, that neither the Company nor the Operating Partnership
     will be liable in any such case to the extent that any such loss, claim,
     damage or liability arises out of or is based upon any untrue statement or
     alleged untrue statement or omission or alleged omission made in such
     registration statement or any amendment thereto, any Preliminary
     Prospectus, the Prospectus and any Integrated Prospectus or any amendment
     or supplement thereto or any Application in reliance upon and in conformity
     with written information furnished to the Company by the Underwriter
     specifically for use therein; and provided, further, that neither the
     Company nor the Operating Partnership will be liable to the Underwriter or
     any person controlling the Underwriter with respect to any such untrue
     statement or omission made in any Preliminary Prospectus that is corrected
     in the Prospectus (or any amendment or supplement thereto) if the person
     asserting any such loss, claim, damage or liability purchased Securities
     from the Underwriter but was not sent or given a copy of the Prospectus (as
     amended or supplemented) at or prior to the written confirmation of the
     sale of such Securities to such person in any case where such delivery of
     the Prospectus (as amended or supplemented) is required by the Act, unless
     such failure to deliver the Prospectus (as amended or supplemented) was a
     result of noncompliance by the Company or the Operating Partnership with
     Sections 5(d) and (e) of this Agreement. This indemnity agreement will be
     in addition to any liability which the Company or the Operating Partnership
     may otherwise have. Neither the Company nor the Operating Partnership will,
     without the prior written consent of the Underwriter, settle or compromise
     or consent to the entry of any judgment in any pending or threatened claim,
     action, suit or proceeding in respect of which indemnification may be
     sought hereunder (regardless of whether the Underwriter or any person who
     controls the Underwriter within the meaning of Section 15 of the Act or
     Section 20 of the Exchange Act is a party to such claim, action, suit or
     proceeding), unless such settlement, compromise or consent includes an
     unconditional release of all of the Underwriter and such controlling
     persons from all liability arising out of such claim, action, suit or
     proceeding.

          (b) The Underwriter will indemnify and hold harmless the Company, each
     of its directors, each of its officers who signed the Registration
     Statement and each person, if any, who controls the Company within the
     meaning of Section 15 of the Act or Section 20 of the Exchange Act against
     any losses, claims, damages or liabilities to which the Company or any such
     director, officer or controlling person may become subject under the Act,
     the Exchange Act or otherwise, insofar as such losses, claims, damages or
     liabilities (or actions in respect thereof) arise out of or are based upon
     (i) any untrue statement or alleged untrue statement of any material fact
     contained in the Registration Statement or any amendment thereto, any
     Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any
     amendment or supplement thereto, or any Application or (ii) the omission or
     the alleged omission to state therein a material fact required to be stated
     in the Registration Statement or any amendment thereto, any Preliminary
     Prospectus, the Prospectus or any Integrated Prospectus or any amendment or
     supplement thereto, or any Application 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 reliance upon and in conformity with written
     information furnished to the Company by the Underwriter specifically for
     use therein; and, subject to the limitation set forth immediately preceding
     this clause, will reimburse, as incurred, any legal or other expenses
     reasonably incurred by the Company or any such director, officer or
     controlling person in connection with investigating or defending any such
     loss, claim, damage, liability or any action in respect thereof. This
     indemnity agreement will be in addition to any liability which the

                                       25
<PAGE>
 
     Underwriter may otherwise have. The Underwriter shall not, without the
     prior consent of the Company, settle or compromise or consent to the entry
     of any judgment in any pending or threatened claim, action, suit or
     proceeding in respect of which indemnification may be sought hereunder
     (regardless of whether the Company, any of its directors or officers who
     signed the Registration Statement or any person who controls the Company
     within the meaning of Section 15 of the Act or Section 20 of the Exchange
     Act is a party to such claim, action, suit or proceeding), unless such
     settlement, compromise or consent includes an unconditional release of the
     Company, its officers and directors who signed the Registration Statement
     and such controlling persons from all liability arising out of such claim,
     action, suit or proceeding.

          (c) 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 the indemnifying party
     under this Section 8, notify the indemnifying party of the commencement
     thereof; but the omission so to notify the indemnifying party will not
     relieve it from (i) any liability which it may have to any indemnified
     party under this Section 8 except to the extent that the indemnifying party
     has been prejudiced as a result thereof or (ii) any liability which it may
     have to any indemnified party otherwise than under this Section 8. In case
     any such action is brought against any indemnified party, and it notifies
     the indemnifying party of the commencement thereof, the indemnifying party
     will be entitled to participate therein and, to the extent that it may
     wish, jointly with any other indemnifying party similarly notified, to
     assume the defense thereof, with counsel satisfactory to such indemnified
     party;  provided, however, that 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 there may be one or
     more legal defenses available to it and/or other indemnified parties which
     are different from or additional to those available to the indemnifying
     party, the indemnifying party shall not have the right to direct the
     defense of such action on behalf of such indemnified party or parties and
     such indemnified party or parties shall have the right to select separate
     counsel to defend such action on behalf of such indemnified party or
     parties. After notice from the indemnifying party to such indemnified party
     of its election so to assume the defense thereof and approval by such
     indemnified party of counsel appointed to defend such action, the
     indemnifying party will not be liable to such indemnified party under this
     Section 8 for any legal or other expenses, other than reasonable costs of
     investigation, 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 in connection with
     such action the indemnifying party shall not be liable for the expenses of
     more than one separate counsel (in addition to local counsel) in any one
     action or separate but substantially similar actions in the same
     jurisdiction arising out of the same general allegations or circumstances,
     designated by the Underwriter in the case of paragraph (a) of this Section
     8, representing the indemnified parties under such paragraph (a) who are
     parties to such action or actions) or (ii) the indemnifying party does not
     promptly retain counsel satisfactory to the indemnified party or (iii) the
     indemnifying party has authorized the employment of counsel for the
     indemnified party at the expense of the indemnifying party. After such
     notice from the indemnifying party to such indemnified party, the
     indemnifying party will not be liable for the costs and expenses of any
     settlement of such action effected by such indemnified party without the
     consent of the indemnifying party.

          (d) In circumstances in which the indemnity agreement provided for in
     the preceding paragraphs of this Section 8 is unavailable or insufficient,
     for any reason, to hold harmless an indemnified party in respect of any
     losses, claims, damages or liabilities (or actions in respect thereof),
     each indemnifying party, in order to provide for just and equitable
     contribution, 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 (i) the relative benefits received by the
     indemnifying party or parties on the one hand and the indemnified party on
     the other from the offering of the Securities or (ii) if the allocation
     provided by the foregoing clause (i) is not permitted by applicable law,
     not only such relative benefits but also the relative fault of the

                                       26
<PAGE>
 
     indemnifying party or parties on the one hand and the indemnified party on
     the other in connection with the statements or omissions or alleged
     statements or omissions that 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 Company and
     the Operating Partnership on the one hand and the Underwriter on the other
     shall be deemed to be in the same proportion as the total proceeds from the
     offering (before deducting expenses) received by the Company bear to the
     total underwriting discounts and commissions received by the Underwriter.
     The relative fault of the parties 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 Company or the Underwriter, the
     parties' relative intent, knowledge, access to information and opportunity
     to correct or prevent such statement or omission, and any other equitable
     considerations appropriate in the circumstances.  The Company and the
     Operating Partnership and the Underwriter agree that it would not be
     equitable if the amount of such contribution were determined by pro rata or
     per capita allocation (even if the Underwriter were treated as one entity
     for such purpose) or by any other method of allocation that does not take
     into account the equitable considerations referred to above in this
     paragraph (d).  Notwithstanding any other provision of this paragraph (d),
     no Underwriter shall be obligated to make contributions hereunder that in
     the aggregate exceed the total public offering price of the Securities
     purchased by the Underwriter under this Agreement, less the aggregate
     amount of any damages that the Underwriter has otherwise been required to
     pay in respect of the same or any substantially similar claim, and no
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation.  For purposes of
     this paragraph (d), each person, if any, who controls the Underwriter
     within the meaning of Section 15 of the Act or Section 20 of the Exchange
     Act shall have the same rights to contribution as the Underwriter, and the
     Company and the Operating Partnership shall be deemed one party and jointly
     and severally liable for any obligations to contribute hereunder and each
     director of the Company, each officer of the Company who signed the
     Registration Statement and each person, if any, who controls the Company
     within the meaning of Section 15 of the Act or Section 20 of the Exchange
     Act, shall have the same rights to contribution as the Company and the
     Operating Partnership.

      9.  Survival.   The respective representations, warranties, agreements,
          --------                                                           
covenants, indemnities and other statements of the Company, its officers, the
Operating Partnership and the Underwriter set forth in this Agreement or made by
or on behalf of them, respectively, pursuant to this Agreement shall remain in
full force and effect, regardless of (i) any investigation made by or on behalf
of the Company, any of its officers or directors, the Operating Partnership, the
Underwriter or any controlling person referred to in Section 8 hereof and (ii)
delivery of and payment for the Securities.  The respective agreements,
covenants, indemnities and other statements set forth in Sections 6 and 8 hereof
shall remain in full force and effect, regardless of any termination or
cancellation of this Agreement.

     10.  Termination.  This Agreement may be terminated with respect to the
          -----------                                                       
Securities in the sole discretion of the Underwriter by notice to the Company
given prior to the Closing Date, in the event that the Company or the Operating
Partnership shall have failed, refused or been unable to perform all obligations
and satisfy all conditions on its part to be performed or satisfied hereunder at
or prior thereto or, if at or prior to the Closing Date, respectively,

          (a) the Company or any of its subsidiaries shall have, in the sole
     judgment of the Underwriter, sustained any material loss or interference
     with its businesses or properties from fire, flood, hurricane, accident or
     other calamity, regardless of whether covered by insurance, or from any
     labor dispute or any legal or governmental proceeding or there shall have
     been any material adverse change, or any development involving a
     prospective material adverse change (including without limitation a change
     in management or control of the Company), in the condition (financial or
     otherwise), business prospects, net worth or results of operations of the
     Company and its subsidiaries, 

                                       27

     taken as a whole, except in each case as described in or contemplated by
     the Registration Statement and the Prospectus (exclusive of any amendment
     or supplement thereto);

               (i)   trading in the Common Stock shall have been suspended by
          the Commission or the New York Stock Exchange;

               (ii)  trading in securities generally on the New York Stock
          Exchange shall have been suspended or minimum or maximum prices shall
          have been established on any such exchange;

               (iii) a banking moratorium shall have been declared by
          authorities of New York, California, Maryland, or the United States of
          America; or

               (iv)  there shall have been (A) an outbreak or escalation of
          hostilities between the United States of America and any foreign
          power, (B) an outbreak or escalation of any other insurrection or
          armed conflict involving the United States of America or (C) any other
          calamity or crisis or material adverse change in general economic,
          political or financial conditions having an effect on the U.S.
          financial markets that, in the judgment of the Underwriter, makes it
          impractical or inadvisable to (x) commence or continue the offering of
