                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of October
23, 2005, by and among PRIME PROPERTY FUND, LLC, a Delaware limited liability
company ("Purchaser"), ATOM ACQUISITION LLC, a Delaware limited liability
company ("Purchaser Acquisition Entity"), ATOM ACQUISITION PARTNERS, L.P., a
Delaware limited partnership ("Purchaser Acquisition LP", and together with
Purchaser and Purchaser Acquisition Entity, the "Purchaser Parties"), AMLI
RESIDENTIAL PROPERTIES TRUST, a Maryland real estate investment trust ("AMLI"),
and AMLI RESIDENTIAL PROPERTIES, L.P., a Delaware limited partnership ("AMLI
LP").

                                    RECITALS

     A. It is proposed that AMLI shall merge (the "Merger") with and into
Purchaser Acquisition Entity with Purchaser Acquisition Entity surviving in
accordance with Title 8 of the Corporations and Associations Article of the
Annotated Code of Maryland ("Title 8") and the Limited Liability Company Act of
the State of Delaware (the "LLC Act"), pursuant to which each of the issued and
outstanding common shares of beneficial interest, par value $0.01 per share, of
AMLI, together with the associated preferred share purchase rights granted
pursuant to the Rights Agreement, dated as of November 2, 1998 (as amended, the
"AMLI Rights Agreement") between AMLI and Harris Trust and Savings Bank as
Rights Agent (together, the "AMLI Common Shares") shall be converted into the
right to receive the Merger Consideration (as defined herein) upon the terms and
subject to the conditions provided herein.

     B. It is proposed that Purchaser Acquisition LP shall merge with and into
AMLI LP (the "Partnership Merger" and, together with the Merger, the "Mergers"),
with AMLI LP surviving on the terms and subject to the conditions set forth in
this Agreement and in accordance with the Delaware Revised Uniform Limited
Partnership Act, as amended ("DRULPA"), pursuant to which each common unit of
limited partnership interest in AMLI LP ("LP Units") shall be converted into the
right to receive the Partnership Merger Consideration (as defined herein) upon
the terms and subject to the conditions provided herein;

     C. The Board of Trustees of AMLI (the "AMLI Board of Trustees") has
received the written opinion (the "Fairness Opinion") of J.P. Morgan Securities
Inc. (the "AMLI Financial Advisor") that, based on, and subject to the various
assumptions and qualifications set forth in such opinion, as of the date of such
opinion, (i) the consideration to be received by holders of AMLI Common Shares
(the "AMLI Common Shareholders") pursuant to this Agreement is fair from a
financial point of view to such holders and (ii) the consideration to be
received by holders of LP Units (the "AMLI LP Unitholders") is fair from a
financial point of view to such holders considered as if such LP Units had been
converted into or redeemed for AMLI Common Shares in accordance with the
existing terms of LP Units.

     D. The AMLI Board of Trustees has (i) determined that the Transaction
Documents (as hereinafter defined), the Merger, and the other transactions
contemplated hereby and thereby, taken together, are fair to, advisable and in
the best interests of AMLI and the AMLI Common Shareholders, (ii) voted to (A)
approve this Agreement and the transactions contemplated hereby, including the
Merger and (B) recommend acceptance and approval by the AMLI Common

<PAGE>

Shareholders of this Agreement, the Merger and the other transactions
contemplated hereby and by the Transaction Documents, (iii) taken all action
necessary to waive the application of the Ownership Limit (as hereinafter
defined) to the purchase or ownership of any AMLI Common Shares acquired
pursuant to the Merger, and (iv) taken all actions necessary to render
inapplicable to each of the transactions contemplated by the Transaction
Documents or exempt such transactions from the provisions of any "fair price",
"moratorium", "control share" or other takeover defense or similar statute or
regulation that would otherwise govern such transactions and the parties hereto,
including Subtitles 6 and 7 of Title 3 of the Maryland General Corporation Law
("MGCL") and Title 8.

     E. The AMLI Board of Trustees on behalf of AMLI as the general partner of
AMLI LP has (i) determined that the Transaction Documents (as hereinafter
defined), the Partnership Merger, and the other transactions contemplated hereby
and thereby, taken together, are fair to, advisable and in the best interests of
AMLI LP and the AMLI Unitholders and (ii) voted to approve this Agreement and
the transactions contemplated hereby, including the Partnership Merger.

     F. The manager of Purchaser, the sole member of Purchaser Acquisition
Entity and Purchaser Acquisition Entity in its capacity as general partner of
Purchaser Acquisition LP, have each approved this Agreement, the Merger or the
Partnership Merger, as applicable, and the other transactions contemplated
hereby.

     G. Purchaser, AMLI and AMLI LP intend that, for U.S. federal income tax
purposes, the Merger will be treated as a taxable purchase of all of the assets
of AMLI directly by Purchaser and the existence of Purchaser Acquisition Entity
shall be disregarded.

     H. Purchaser, AMLI and AMLI LP intend that, for U.S. federal income tax
purposes, the Partnership Merger will be treated as a taxable sale of interests
in AMLI LP.

     I. As an inducement to the Purchaser Parties entering into this agreement
and incurring the obligations set forth herein, concurrently with the execution
and delivery of this Agreement, certain officers of AMLI are each entering into
a Voting Agreement (a "Voting Agreement") relating to the AMLI Common Shares
owned by such officers.

     J. Certain capitalized terms used in this Agreement are defined in Article
IX.

                                    AGREEMENT

     In consideration of the representations, warranties, covenants and
agreements contained in this Agreement, the parties agree as follows:

          quarter for which full quarterly dividends on the AMLI Common Shares
          have been declared and paid and the Closing Date (including the
          Closing Date) by (y) the total number of days in the quarter in which
          the Closing Date occurs without interest (such sum, the "Series D
          Merger Consideration").

All such Preferred Shares, when so converted, shall no longer be outstanding and
shall automatically be canceled and retired and shall cease to exist, and each

withholding Tax. Notwithstanding the foregoing, if the exercise price per share
provided for in any AMLI Option exceeds $37.75, no cash shall be paid with
regard to such AMLI Option to the holder of such AMLI Option. Prior to the
Merger Effective Time, Purchaser and AMLI shall establish a procedure to effect
the surrender of AMLI Options contemplated by this Section 1.8(a). In connection
with the Merger, as of the Merger Effective Time, any restrictions with respect
to outstanding restricted shares awarded under the AMLI Executive Share Purchase
Plan, as amended and restated (the "ESPP"), and the AMLI Senior Officer Share
Acquisition Plan (the "Restricted Share Plan") shall terminate or lapse. After
such restrictions terminate or lapse, the shares relating thereto shall be
automatically converted into the right to receive the Merger Consideration on
the terms and conditions set forth in the applicable sections of this Article I.

          (b) AMLI covenants that the AMLI Option Plan shall terminate as of the
Merger Effective Time and all awards issued under such AMLI Option Plan shall be
terminated and the provisions in any other plan, program, arrangement or
agreement providing for the issuance or grant of any other interest in respect
of the equity interests of AMLI or any of the AMLI Subsidiaries shall be of no
further force or effect and shall be deemed to be terminated as of the Merger
Effective Time and no holder of an AMLI Option or any participant in any AMLI
Option Plan shall have any right thereunder to (i) acquire any securities of
AMLI, the Surviving Entity or any Subsidiary thereof or (ii) receive any payment
or benefit with respect to any award previously granted under the AMLI Option
Plan except as provided in Section 1.8(a).

     Section 1.9 Termination of ESPP and Restricted Share Plan. AMLI shall (i)
concurrently with the execution of this Agreement, suspend the ESPP and (ii)
effective as of the Merger Effective Time, terminate each of the ESPP and the
Restricted Share Plan and ensure that no employee of AMLI or any AMLI Subsidiary
has rights to acquire any interest in the Surviving Entity, Purchaser or any
Purchaser Subsidiary, including Purchaser Acquisition Entity at or after the
Merger Effective Time.

     Section 1.10 Termination of DRIP. AMLI shall terminate AMLI's Dividend
Reinvestment Plan (the "DRIP"), effective prior to the Merger Effective Time,
and ensure that no purchase or other rights under the DRIP enable the holder of
such rights to acquire any interest in the Surviving Entity, Purchaser or any
Purchaser Subsidiary, including Purchaser Acquisition Entity, as a result of
such purchase or the exercise of such rights at or after the Merger Effective
Time.

          (b) Exchange Procedures.

               (i) As promptly as practicable following the Merger Effective
          Time (but in no event later than five (5) Business Days), the
          Purchaser shall cause the Exchange Agent to mail to (A) each holder of
          record of a certificate or certificates (each, a "Common Share
          Certificate") that immediately prior to the Merger Effective Time
          represented outstanding AMLI Common Shares whose shares were converted
          into the right to receive the Merger Consideration pursuant to Section
          1.4(b) and (B) each holder of record of a certificate or certificates
          (each, a "Preferred Share Certificate") that immediately prior to the
          Merger Effective Time represented outstanding Series B Preferred
          Shares or Series D Preferred Shares whose preferred shares were
          converted into the right to receive the Series B Merger Consideration
          or the Series D Merger Consideration, as applicable, pursuant to
          Section 1.4(c): (x) a letter of transmittal (a "Letter of
          Transmittal") which shall specify that delivery shall be effected and
          risk of loss and title to the Common Share Certificates or Preferred
          Share Certificate, as the case may be, shall pass only upon delivery
          of the Common Share Certificates or Preferred Share Certificates, as
          applicable, to the Exchange Agent and shall be in such form and have
          such other provisions as the Surviving Entity may reasonably specify;
          and (y) instructions for use in effecting the surrender of the Common
          Share Certificates in exchange for the Merger Consideration or the
          Preferred Share Certificates in exchange for the Series B Merger
          Consideration or the Series D Merger Consideration, as applicable.

               (ii) Upon surrender of a Common Share Certificate for
          cancellation to the Exchange Agent, together with a Letter of
          Transmittal, duly executed, and any other documents reasonably
          required by the Exchange Agent or the Surviving Entity, (A) the holder
          of such Common Share Certificate shall be entitled to

<PAGE>

          receive in exchange therefor a check in the amount equal to the per
          share cash amount of the Merger Consideration, which such holder has
          the right to receive pursuant to the provisions of Section 1.4(b); and
          (B) the Common Share Certificate so surrendered shall forthwith be
          canceled. Until surrendered as contemplated by this Section 2.1, each
          such Common Share Certificate shall be deemed at any time after the
          Merger Effective Time to represent only the right to receive upon such
          surrender the Merger Consideration.

               (iii) In the event of a transfer of ownership of AMLI Common
          Shares which is not registered in the transfer records of AMLI, the
          Merger Consideration shall be paid to a transferee if (A) the Common
          Share Certificate representing such AMLI Common Shares is presented to
          the Exchange Agent properly endorsed or accompanied by appropriate
          stock powers and otherwise in proper form for transfer and accompanied
          by all documents reasonably required by the Exchange Agent to evidence
          and effect such transfer and (B) such transferee shall pay any
          transfer or other taxes required by reason of the payment to a person
          other than the registered holder of the Common Share Certificate or
          establish to the satisfaction of the Exchange Agent and the Surviving
          Entity that such tax has been paid or is not applicable.

               (iv) Upon surrender of a Preferred Share Certificate for
          cancellation to the Exchange Agent, together with a Letter of
          Transmittal, duly executed, and any other documents reasonably
          required by the Exchange Agent or the Surviving Entity, (A) the holder
          of such Preferred Share Certificate shall be entitled to receive in
          exchange therefore a check in the amount equal to the per share cash
          amount of the Series B Merger Consideration or the Series D Merger
          Consideration which such holder has the right to receive pursuant to
          the provisions of Section 1.4(c); and (B) the Preferred Share
          Certificate so surrendered shall forthwith be canceled. Until
          surrendered as contemplated by this Section 2.1, each such Preferred
          Share Certificate shall be deemed at any time after the Merger
          Effective Time to represent only the right to receive upon such
          surrender the Series B Merger Consideration or Series D Merger
          Consideration, as applicable.

               (v) In the event of a transfer of ownership of Preferred Shares

          powers and otherwise in proper form for transfer and accompanied by
          all documents reasonably required by the Exchange Agent to evidence
          and effect such transfer and (B) such transferee shall pay any
          transfer or other taxes required by reason of the payment to a person
          other than the registered holder of the Preferred Share Certificate or
          establish to the satisfaction of the Exchange Agent and the Surviving
          Entity that such tax has been paid or is not applicable.

          (c) Payment with respect to LP Units.

               (i) As promptly as practicable after the Partnership Merger
          Effective Time (but in no event later than five (5) Business Days),
          the Purchaser shall cause the Exchange Agent to mail to each holder of
          LP Units registered on the transfer books of AMLI LP immediately prior
          to the Partnership Merger Effective Time (x) a letter of transmittal
          (a "Unitholder Letter of Transmittal") which shall certify to the
          Purchaser and to the Exchange Agent the number of LP Units held by
          such holder and shall be in such form and have such other provisions
          as the Surviving Entity may reasonably specify; and (y) instructions
          for use in effecting the delivery of the Unitholder Letter of
          Transmittal in order to receive the Partnership Merger Consideration.

               (ii) Upon delivery of a Unitholder Letter of Transmittal, duly
          executed, and any other documents reasonably required by the Exchange
          Agent or the Surviving Entity, the holder of the LP Units identified
          in such Unitholder Letter of Transmittal shall be entitled to a check
          in the amount equal to the per unit cash amount of the Partnership
          Merger Consideration, which such holder has the right to receive
          pursuant to the provisions of Section 1.5.

               (iii) In the event of a transfer of ownership of LP Units which
          is not registered in the transfer records of AMLI LP, the Partnership
          Merger Consideration shall be paid to a transferee if (A) such
          transferee delivers a Unitholder Letter of Transmittal in accordance
          with Section 2.1(c)(i) and (B) such transferee shall pay any transfer
          or other taxes required by reason of the payment to a person other
          than the registered holder of the LP Unit or establish to the
          satisfaction of the Exchange Agent and the Surviving Partnership that
          such tax has been paid or is not applicable.

          (d) Tax Characterizations. Purchaser and AMLI intend that, for U.S.
federal and state income tax purposes, the Merger shall be treated as a taxable
sale by AMLI of all of AMLI's assets to Purchase Acquisition Entity in exchange
for the Merger Consideration, the Series B Merger Consideration and the Series D
Merger Consideration and the assumption of AMLI's liabilities, followed by a
liquidating distribution of such Merger Consideration, Series B Merger
Consideration and Series D Merger Consideration to the holders of AMLI Common
Shares, Series B Preferred Shares and Series D Preferred Shares, as applicable,
pursuant to Section 331 and Section 562 of the Code. This Agreement shall
constitute a "plan of liquidation" of AMLI for U.S. federal income tax purposes.
Purchaser and AMLI LP intend that, for U.S. federal and state income tax
purposes, the Partnership Merger shall be treated as a taxable purchase of LP
Units directly by Purchaser Acquisition Entity and that the separate existence
of Purchaser Acquisition LP shall be disregarded.

          (e) No Further Ownership Rights.

               (i) The Merger Consideration paid upon the surrender for exchange
          of the Common Share Certificates representing AMLI Common Shares in
          accordance with the terms hereof shall be deemed to have been paid in
          full


                                      -10-

<PAGE>

          satisfaction of all rights pertaining to such AMLI Common Shares and,
          after the Merger Effective Time, there shall be no further
          registration of transfers on the transfer books of the Surviving
          Entity of the AMLI Common Shares. If, after the Merger Effective Time,
          Common Share Certificates are presented to the Surviving Entity, for
          any reason, they shall be canceled and exchanged as provided in this
          Article II.

               (ii) The Series B Merger Consideration and Series D Merger
          Consideration paid upon the surrender for exchange of the Preferred
          Share Certificates representing Preferred Shares in accordance with
          the terms hereof shall be deemed to have been paid in full
          satisfaction of all rights pertaining to such Preferred Shares and,
          after the Merger Effective Time, there shall be no further
          registration of transfers on the transfer books of the Surviving
          Entity of the Preferred Shares. If, after the Merger Effective Time,
          Preferred Share Certificates are presented to the Surviving Entity,
          for any reason, they shall be canceled and exchanged as provided in
          this Article II.

               (iii) The Partnership Merger Consideration paid with respect to
          the LP Units in accordance with the terms hereof shall be deemed to
          have been paid in full satisfaction of all rights pertaining to such
          LP Units and, after the Partnership Merger Effective Time, there shall
          be no further registration of transfers on the transfer books of the
          Surviving Partnership, of the LP Units.

          (f) Termination of Exchange Fund. Any portion of the Exchange Fund
(including any interest and other income received with respect thereto) that
remains undistributed to the former holders of AMLI Common Shares, Preferred
Shares or LP Units on the first anniversary of the Merger Effective Time shall
be delivered to the Purchaser, as applicable, upon demand, and any former
holders of AMLI Common Shares, Preferred Shares or LP Units who have not
theretofore received any applicable Merger Consideration, Series B Merger
Consideration, Series D Merger Consideration or Partnership Merger
Consideration, as applicable, to which they are entitled under this Article II,
shall thereafter look only to the Surviving Entity or the Surviving Partnership,
as applicable, for payment of their claims with respect thereto.

          (g) No Liability. None of Purchaser, Purchaser Acquisition Entity,
Purchaser Acquisition LP, the Surviving Entity or the Surviving Partnership
shall be liable to any holder of AMLI Common Shares, Preferred Shares or LP
Units for any part of the Merger Consideration, Series B Merger Consideration,
Series D Merger Consideration or Partnership Merger Consideration, as
applicable, delivered to a public official pursuant to any applicable abandoned
property, escheat or similar Law. Any amounts remaining unclaimed by holders of
any such shares immediately prior to the time at which such amounts would
otherwise escheat to, or become property of, any federal, state or local
government or any court, regulatory or administrative agency or commission,
governmental arbitrator or other governmental authority or instrumentality,
domestic or foreign (a "Governmental Entity"), shall, to the extent permitted by
applicable Law, become the property of the Surviving Entity or the Surviving
Partnership, as a applicable, free and clear of any claims or interest of any
such holders or their successors, assigns or personal representatives previously
entitled thereto.

          (h) Lost, Stolen or Destroyed Certificates. If any Common Share
Certificate or Preferred Share Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming

by such Person of a bond in such reasonable amount as Purchaser or the Surviving
Entity may direct as indemnity against any claim that may be made against it
with respect to such Common Share Certificate or Preferred Share Certificate,
the Exchange Agent shall pay in exchange for such lost, stolen or destroyed
Common Share Certificate the appropriate amount of the Merger Consideration or
shall pay in exchange for such lost, stolen or destroyed Preferred Share
Certificate the appropriate amount of the Series B Merger Consideration or
Series D Merger Consideration, as applicable.

          (i) Withholding of Tax. Purchaser, the Surviving Entity, the Surviving
Partnership or the Exchange Agent shall be entitled to deduct and withhold from

Units such amount as Purchaser, the Surviving Entity, the Surviving Partnership,
any Affiliate of the Surviving Entity or the Surviving Partnership or the
Exchange Agent is required to deduct and withhold with respect to the making of
such payment under the Code or any provision of state, local or foreign Law
related to Taxes. To the extent that amounts are so withheld by the Surviving
Entity, the Surviving Partnership or the Exchange Agent, such withheld amounts
shall be (i) paid over to the applicable Governmental Entity in accordance with
applicable Law and (ii) treated for all purposes of this Agreement as having
been paid to the former holder of AMLI Common Shares, Preferred Shares or LP
Units in respect of which such deduction and withholding was made by the
Surviving Partnership or the Exchange Agent.

          (j) No Dissenters' Rights. No dissenters' or appraisal rights shall be

transactions contemplated hereby; provided, that the provisions of Section

          (k) Additional Actions. If, at any time after the Merger Effective

                                  ARTICLE III.

                         REPRESENTATIONS AND WARRANTIES

     Section 3.1 Representations and Warranties of AMLI. AMLI and AMLI LP
represent and warrant to Purchaser, Purchaser Acquisition Entity and Purchaser
Acquisition LP as follows:

          (a) Organization, Standing and Trust Power of AMLI. AMLI is a real
estate investment trust duly formed, validly existing and in good standing under
the Laws of the State of Maryland and has all of the requisite power, authority
and all necessary government approvals or licenses to own, lease, operate its
properties, and to carry on its business as now being conducted. AMLI is duly
qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of the business it is conducting, or the
ownership, operation or leasing of its properties or the management of
properties for others makes such qualification or licensing necessary, other
than in such jurisdictions where the failure to be so qualified or licensed or
in good standing would not, individually or in the aggregate, constitute an AMLI
Material Adverse Effect. AMLI has heretofore made available to Purchaser
complete and correct copies of AMLI's Amended and Restated Declaration of Trust,
as amended and supplemented through the date hereof (the "AMLI Charter"), and
Amended and Restated Bylaws, as amended through the date hereof (the "AMLI
Bylaws"). The AMLI Charter and the AMLI Bylaws are each in full force and
effect. Each jurisdiction in which AMLI is qualified or licensed to do business
and each assumed name under which it conducts business in any jurisdiction are
identified in Section 3.1(a) of the disclosure letter, dated the date hereof and
delivered to Purchaser in connection with the execution and delivery of this
Agreement (the "AMLI Disclosure Letter").

          (b) AMLI Subsidiaries; Interests in Other Persons.

               (i) Each AMLI Subsidiary is duly organized, validly existing and
          in good standing under the Laws of its jurisdiction of formation and
          has all of the requisite corporate, partnership, limited liability
          company or other organizational power and authority and all necessary
          government approvals and licenses to own, lease and operate its
          properties and to carry on its business as now being conducted, except
          where the failure to have such approvals or licenses would not,
          individually or in the aggregate, constitute an AMLI Material Adverse
          Effect. Each AMLI Subsidiary is duly qualified or licensed to do
          business and is in good standing in each jurisdiction in which the
          nature of its business or the ownership, operation or leasing of its
          properties or the management of properties for others makes such
          qualification or licensing necessary, other than in such jurisdictions
          where the failure to be so qualified or licensed or in good standing
          would not, individually or in the aggregate, constitute an AMLI
          Material Adverse Effect. Section 3.1(b)(i) of the AMLI Disclosure
          Letter sets forth (A) all AMLI Subsidiaries and their respective
          jurisdictions of formation, (B) each owner and the respective amount
          of such owner's equity interest in each AMLI Subsidiary and (C) a list
          of each jurisdiction in which each AMLI Subsidiary is qualified or
          licensed to do business and each assumed name under which each such
          AMLI Subsidiary conducts business in any jurisdiction. All outstanding
          equity interests


                                      -13-

<PAGE>

          in each AMLI Subsidiary have been duly authorized and are validly
          issued, fully paid and (except for general partnership interests)
          non-assessable, and are not subject to any preemptive rights and are
          owned by AMLI, except as disclosed in Section 3.1(b)(i) of the AMLI
          Disclosure Letter, and are so owned free and clear of all pledges,
          claims, liens, charges, encumbrances and security interests of any
          kind or nature whatsoever (collectively, "Liens"). Except as set forth
          in Section 3.1(b)(i) or Section 3.1(c)(i)(D) of the AMLI Disclosure
          Letter, there are no outstanding options, warrants or other rights to
          acquire ownership interests from any AMLI Subsidiary. AMLI has
          heretofore made available to Purchaser complete and correct copies of
          the charter, bylaws or other organizational documents of each of the
          AMLI Subsidiaries, each as amended to the date hereof and each as in
          full force and effect.

               (ii) Except for the stock of, or other equity interests in, the
          AMLI Subsidiaries disclosed in Section 3.1(b)(i) of the AMLI
          Disclosure Letter, and the other interests disclosed in Section
          3.1(b)(ii) of the AMLI Disclosure Letter (the "AMLI Other Interests"),
          neither AMLI nor any of the AMLI Subsidiaries owns any stock or other
          ownership or equity interest in any Person. Neither AMLI nor any AMLI
          Subsidiary has violated any provision of any organizational documents
          governing or otherwise relating to its rights in any AMLI Other
          Interest that would, individually or in the aggregate, constitute an
          AMLI Material Adverse Effect.

          (c) Capital Structure.

               (i) Shares

                    (A) The authorized shares of beneficial interest of AMLI
               consist of an aggregate of 150,000,000 shares, par value, $0.01

          (e) SEC Documents.

               (i) AMLI has made available to Purchaser (by public filing with
          the SEC or otherwise) a true and complete copy of each report,

          1, 2002 and prior to or on the Closing Date (the "AMLI SEC
          Documents"), which are all the documents (other than preliminary
          material) that AMLI was required to file with the SEC since January 1,
          2002 through the date hereof pursuant to the federal securities laws
          and the SEC rules and regulations thereunder. As of their respective
          dates, the AMLI SEC Documents complied in all material respects with
          the requirements of the Securities Act of 1933, as amended (the
          "Securities Act"), or the Exchange Act, as the case may be, and the
          rules and regulations of the SEC thereunder applicable to such AMLI
          SEC Documents, in each case as in effect at such time, and none of the
          AMLI SEC Documents contained any untrue statement of a material fact
          or omitted to state a material fact required to be stated therein or
          necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading, except to
          the extent such statements have been modified or superseded by later
          AMLI SEC Documents filed and publicly available prior to the date of
          this Agreement. AMLI does not have any outstanding and unresolved
          comments from the SEC with respect to any of the AMLI SEC Documents.
          The consolidated financial statements of AMLI (including the notes
          thereto) included in the AMLI SEC Documents complied as to form in all
          material respects with the applicable accounting requirements and the
          published rules and regulations of the SEC with respect thereto, were
          prepared in accordance with generally accepted accounting principles
          ("GAAP") applied on a consistent basis during the periods involved
          (except as may be indicated in the notes thereto, or, in the case of
          the unaudited statements, as permitted by Rule 10-01 of Regulation S-X
          of the SEC) and fairly present, in accordance with applicable
          requirements of GAAP and the applicable rules and regulations of the
          SEC (subject, in the case of the unaudited statements, to normal,
          recurring adjustments, none of which are material), in each case as in
          effect at such time, the assets, liabilities and the consolidated
          financial position of AMLI and the AMLI Subsidiaries, taken as a
          whole, as of their respective dates and the consolidated results of
          operations and cash flows of AMLI and the AMLI Subsidiaries taken as a
          whole, for the periods presented therein. The books of account and
          other financial records of AMLI and the AMLI Subsidiaries are
          accurately reflected in all material respects in the financial
          statements included in the AMLI SEC Documents. No AMLI Subsidiary is
          required to make any filing with the SEC.

               (ii) Section 3.1(e)(ii) of the AMLI Disclosure Letter sets forth
          a true and complete copy of the unaudited consolidated balance sheet
          of AMLI as at June 30, 2005 (the "Balance Sheet") and the unaudited
          consolidated statements of income for the six months ended June 30,
          2005 and June 30, 2004 (together with the Balance Sheet, the "Interim
          Financial Information"). The Interim Financial Information was
          prepared in accordance with GAAP (except for the absence of footnotes)
          applied on a basis consistent with the consolidated financial
          statements included in the AMLI SEC Documents and fairly presents in
          all material respects (subject to normal recurring adjustments, none
          of which are material), the assets, liabilities, consolidated
          financial position and consolidated results of operations and cash
          flows of AMLI and the AMLI Subsidiaries taken as a whole as at and for
          the periods indicated. The books of account and other financial
          records of AMLI and the AMLI Subsidiaries are accurately reflected in
          all material respects in the Interim Financial Information.

               (iii) Each AMLI SEC Document filed since July 31, 2002, was
          accompanied by the certifications required to be filed or submitted by
          Parent's chief executive officer and chief financial officer pursuant
          to the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") and, at
          the time of filing or submission of each such certification, such
          certification was true and accurate and complied with the
          Sarbanes-Oxley Act.

          (f) Absence of Certain Changes or Events. Except as disclosed in
Section 3.1(f) of the AMLI Disclosure Letter, since the Balance Sheet date, AMLI

consistent with past practices) other employee, of AMLI or the AMLI
Subsidiaries, any grant of severance or termination pay or benefits (or any
increase in the amount of such pay or benefits) to any current or former
director, trustee, officer or other employee, of AMLI or the AMLI Subsidiaries
that would be payable after the Merger Effective Time, or the entering into, or
amendment of, any employment, severance, change in control, tax gross-up,
deferred compensation, retention, special or stay bonus or any other similar
agreements or arrangements; (G) any change, event, effect, damage, destruction,
loss relating to the business or operations of AMLI that, individually or in the
aggregate, has constituted, or would constitute, an AMLI Material Adverse
Effect; (H) any incurrence, assumption or guarantee by AMLI or any AMLI
Subsidiary of any indebtedness for borrowed money other than in the ordinary
course of business consistent with past practice; (I) any creation or assumption
by AMLI or any AMLI Subsidiary of any Lien in an amount, individually or in the
aggregate, in excess of $2,000,000 on any asset other than in the ordinary


                                      -20-

course of business consistent with past practices; (J) any material commitment,
contractual obligation (including, without limitation, any management or
franchise agreement, any lease (capital or otherwise) or any letter of intent),
borrowing, guaranty, capital expenditure or transaction entered into by AMLI or
by any AMLI Subsidiary other than in the ordinary course of business consistent
with past practice; or (K) any making of any loan, advance or capital
contribution to or investment in any Person; or (2) any split, combination or
reclassification of any of AMLI's stock or any issuance or the authorization of
any issuance of any other securities in respect of, in lieu of or in
substitution for, or giving the right to acquire by exchange or exercise, shares
of its stock or any issuance of an ownership interest in, any AMLI Subsidiary.

          (g) No Undisclosed Material Liabilities. Except as disclosed in the
AMLI SEC Documents filed prior to the date hereof, as set forth in Section
3.1(g)(i) of the AMLI Disclosure Letter, there are no Liabilities of AMLI or any
of the AMLI Subsidiaries, whether accrued, contingent, absolute or determined,
and, except with respect to the environmental matters which are the subject of
the representations and warranties in Section 3.1(o), there is no existing
condition, situation or set of circumstances that could reasonably be expected
to result in such a Liability, other than: (i) Liabilities adequately provided
for on the Balance Sheet, (ii) Liabilities incurred in the ordinary course of
business consistent with past practice subsequent to the Balance Sheet date and
(iii) such other Liabilities as would not, individually or in the aggregate,
constitute an AMLI Material Adverse Effect. Section 3.1(g)(ii) of the AMLI
Disclosure Letter sets forth a complete list of all loan or credit agreements,
notes, bonds, mortgages, indentures and other agreements and instruments
pursuant to which any indebtedness of AMLI or any AMLI Subsidiary, is
outstanding or may be incurred and the respective principal amounts outstanding
thereunder as of September 30, 2005. For purposes of this Agreement,
"indebtedness" means, with respect to any Person, without duplication (i) all
obligations of such Person for borrowed money, or with respect to deposits or
advances of any kind to such person, (ii) all obligations of such Person
evidenced by bonds, debentures, notes or similar instruments, (iii) all
obligations of such Person upon which interest charges are paid by such Person,
(iv) all obligations of such Person issued or assumed as the deferred purchase
price of property or services (excluding obligations of such person to trade
creditors for raw materials, inventory, services and supplies incurred in the
ordinary course of such Person's business, consistent with past practice), (v)
all capitalized lease obligations of such Person, (vi) all obligations of such
Person under interest rate or currency hedging transactions (valued at the
termination value thereof), (vii) all letters of credit issued for the account
of such Person, and (viii) all guarantees or keepwell agreements in respect of
any indebtedness of any other Person.

          (h) No Default. Neither AMLI nor any of the AMLI Subsidiaries is or
has been in default or violation (and no event has occurred which, with notice
or the lapse of time or both, would constitute a default or violation) of any
term, condition or provision of (A) the AMLI Charter or the AMLI Bylaws or the
comparable charter or organizational documents of any of the AMLI Subsidiaries,
(B) any loan or credit agreement or any note, bond, mortgage, indenture, lease
or other agreement, instrument, permit, concession, franchise or license to
which AMLI or any of the AMLI Subsidiaries is now a party or by which AMLI or
any of the AMLI Subsidiaries or any of their respective properties or assets is
bound, or (C) any Law or Order applicable to or binding upon AMLI or any of the
AMLI Subsidiaries or any of their respective properties or assets, except, in
the case of clauses (B) and (C), for defaults or violations which,


                                      -21-

<PAGE>

individually or in the aggregate, have not constituted, and would not
constitute, an AMLI Material Adverse Effect.

          (i) Compliance with Applicable Laws. AMLI and the AMLI Subsidiaries
hold all permits, licenses, certificates, registrations, variances, exemptions,
orders, franchises and approvals of all Governmental Entities necessary or
required by any applicable Law or Order for the lawful conduct of their
respective businesses (together with the AMLI Environmental Permits (as
hereinafter defined), the "AMLI Permits"), except where the failure so to hold,
individually or in the aggregate, does not and would not constitute an AMLI
Material Adverse Effect. AMLI and the AMLI Subsidiaries are in compliance with
the terms of the AMLI Permits, except where the failure to so comply,
individually or in the aggregate, does not and would not constitute an AMLI
Material Adverse Effect. Except as would not, individually or in the aggregate,
constitute an AMLI Material Adverse Effect, the businesses of AMLI and the AMLI
Subsidiaries are not being and have not been conducted in violation of any Law
or Order. No investigation or review by any Governmental Entity with respect to
AMLI or any of the AMLI Subsidiaries is pending or, to the Knowledge of AMLI, is
threatened, other than those the outcome of which, individually or in the
aggregate, would not constitute an AMLI Material Adverse Effect.

          (j) Litigation. Except as set forth in Section 3.1(j) of the AMLI
Disclosure Letter, there is no litigation, arbitration, claim, investigation,
suit, action or proceeding pending or, to the Knowledge of AMLI, threatened
against or affecting AMLI or any AMLI Subsidiary or any of their respective
property or assets that, individually or in the aggregate, constitutes or would
constitute an AMLI Material Adverse Effect, nor is there any such litigation,
arbitration, claim, investigation, suit, action or proceeding or any Order
outstanding against AMLI or any AMLI Subsidiary or any of their respective
properties or assets which in any manner challenges or seeks to prevent or
enjoin, alter or materially delay the Merger or the Partnership Merger or the
other transactions contemplated by the Transaction Documents.

          (k) Taxes.

               (i) Each of AMLI and each AMLI Subsidiary has timely filed or has
          had timely filed on its behalf all Tax Returns required to be filed by
          it or on its behalf (after giving effect to any filing extension
          properly granted by a Governmental Entity having authority to do so or
          otherwise permitted by Law). Each such Tax Return was, at the time
          filed, true, correct and complete in all material respects. Each of
          AMLI and the AMLI Subsidiaries has paid (or AMLI has paid on behalf of
          such AMLI Subsidiary), within the time and in the manner prescribed by
          Law, all material Taxes that are due and payable. The most recent
          financial statements contained in the AMLI SEC Documents filed with
          the SEC prior to the date of this Agreement reflect an adequate
          reserve or accrued liabilities or expenses for all material Taxes due
          and payable by AMLI and the AMLI Subsidiaries as a group for all
          taxable periods and portions thereof through the date of such
          financial statements. AMLI and the AMLI Subsidiaries (as a group) have
          established on their books and records (which may, but are not
          required to, be reflected only on the books and records of AMLI or
          AMLI LP) reserves or accrued liabilities or expenses that are adequate
          for the payment of all


                                      -22-

<PAGE>

          Taxes for which AMLI or any AMLI Subsidiary is liable but are not yet
          due and payable. AMLI has incurred no liability for any Taxes under
          Sections 857(b), 860(c) or 4981 of the Code or Treasury Regulation
          Sections 1.337(d)-5, 1.337(d)-6 or 1.337(d)-7, including, without
          limitation, any Tax arising from a prohibited transaction described in
          Section 857(b)(6) of the Code and the excise tax on redetermined
          rents, redetermined deductions, and excess interest under Section
          857(b)(7) of the Code; and neither AMLI nor any of the AMLI
          Subsidiaries has incurred any material liability for Taxes other than
          in the ordinary course of business and other than transfer or similar
          Taxes arising in connection with the sale of property. No deficiencies
          for material Taxes have been asserted or assessed in writing by a
          Governmental Entity against AMLI or any of the AMLI Subsidiaries, and
          no requests for waivers of the time to assess any such material Taxes
          have been granted and remain in effect or are pending. No claim is
          pending or proposed by any Governmental Entity in any jurisdiction
          where AMLI or any AMLI Subsidiary does not file Tax Returns that AMLI
          or any AMLI Subsidiary is or may be subject to taxation by such
          jurisdiction, nor to the Knowledge of AMLI are there any facts that
          could reasonably be expected to give rise to such a claim. Copies of
          all material Tax Returns with respect to taxable years commencing on
          or after the taxable year ending December 31, 1999 have been delivered
          to or made available to representatives of Purchaser.

               (ii) Each of AMLI and the AMLI Subsidiaries that file Tax Returns
          as a REIT (as defined herein) (A) for each taxable period beginning
          with its date of formation through its most recent taxable year ended
          on or before the date hereof, has been subject to taxation as a real
          estate investment trust (a "REIT") within the meaning of the Code and
          has satisfied the requirements to qualify as a REIT for such years,
          (B) has operated consistent with the requirements for qualification
          and taxation as a REIT for the period from the end of its most recent
          taxable year ended before the date hereof through the date hereof, (C)
          has not taken any action or omitted to take any action which would
          reasonably be expected to result in a successful challenge by the
          Internal Revenue Service to its status as a REIT, and no such
          challenge is pending, or to AMLI's Knowledge, threatened and (D)
          intends to continue to operate in such a manner as to permit it to
          continue to qualify as a REIT for the taxable year or portion thereof
          that will end with the Merger. Each AMLI Subsidiary which files Tax
          Returns as a partnership or is a disregarded entity for U.S. federal
          income tax purposes has since its acquisition by AMLI been classified
          for U.S. federal income tax purposes as a partnership or disregarded
          entity, as the case may be, and not as an association taxable as a
          corporation, or a "publicly traded partnership" within the meaning of
          Section 7704(b) of the Code that is treated as a corporation for U.S.
          federal income tax purposes under Section 7704(a) of the Code. Each
          AMLI Subsidiary which is a corporation has been since its formation
          classified as a qualified REIT subsidiary under Section 856(i) of the
          Code, a taxable REIT subsidiary under Section 856(l) of the Code or as
          a REIT under Sections 856 through 860 of the Code.

               (iii) As of the date of this Agreement, AMLI does not have any
          earnings and profits attributable to AMLI or any other corporation in
          any non-REIT year within the meaning of Section 857 of the Code.

               (iv) All material Taxes which AMLI or the AMLI Subsidiaries are
          required by Law to withhold or collect, including material Taxes
          required to have been withheld in connection with amounts paid or
          owing to any employee, independent contractor, creditor, shareholder
          or other third party and sales, gross receipts and use taxes, have
          been duly withheld or collected and, to the extent required, have been
          paid over to the proper Governmental Entities or, if not yet due, are
          held in separate bank accounts for such purpose. There are no Liens
          for material Taxes upon the assets of AMLI or the AMLI Subsidiaries
          except for statutory Liens for Taxes not yet due.

               (v) Except as set forth in Section 3.1(k)(v) of the AMLI
          Disclosure Letter: (A) there are no audits by or contests with any
          taxing authority currently being conducted with regard to material
          Taxes or Tax Returns of AMLI or any AMLI Subsidiary; (B) there are no
          audits pending with or proposed in writing by any taxing authority
          with respect to any material Taxes or Tax Returns; (C) neither AMLI
          nor any AMLI Subsidiary is a party to any litigation or administrative
          proceeding relating to any material Taxes; and (D) neither AMLI nor
          any AMLI Subsidiary has requested, received or is subject to any
          written ruling of a taxing authority or has entered into any written
          agreement with a taxing authority with respect to any material Taxes.

               (vi) Except as set forth in Section 3.1(k)(vi) of the AMLI
          Disclosure Letter, neither AMLI nor the AMLI Subsidiaries are a party
          to any Tax allocation or sharing agreement.

               (vii) AMLI and the AMLI Subsidiaries do not have any material
          liability for the Taxes of any Person other than AMLI and the AMLI
          Subsidiaries (A) under Treasury Regulation Section 1.1502-6 (or any
          similar provision of state, local or foreign Law) or (B) as a
          transferee or successor.

               (viii) Except as set forth in Section 3.1(k)(viii) or Section
          3.1(l)(iii)(F) of the AMLI Disclosure Letter, neither AMLI nor the
          AMLI Subsidiaries have made any payments, are obligated to make any
          payments, or are parties to an agreement that could obligate them to
          make any payments that will not be deductible under Section 280G of
          the Code.

               (ix) Neither AMLI nor any AMLI Subsidiary holds any asset the
          disposition of which would be subject to rules similar to Section 1374
          of the Code.

               (x) There are no Tax Protection Agreements except as disclosed in
          Section 3.1(k)(x) of the AMLI Disclosure Letter.

          (l) Pension and Benefit Plans; ERISA.

               (i) Except as set forth in Section 3.1(l)(i) of the AMLI
          Disclosure Letter, neither AMLI, any AMLI Subsidiary nor any of their
          respective ERISA Affiliates is a party to, sponsors, participates in,
          contributes to or has any liability or contingent liability with
          respect to:

                    (A) any "employee welfare plan" or "employee pension benefit
               plan" (as those terms are respectively defined in Sections 3(1)
               and 3(2) of the Employee Retirement Income Security Act of 1974,
               as amended ("ERISA")), other than a "multiemployer plan" (as
               defined in Section 3(37) of ERISA);

                    (B) any retirement or deferred compensation plan, incentive
               compensation plan, stock plan, profit-sharing, unemployment
               compensation plan, vacation pay, severance pay, post-employment,
               supplemental employment or unemployment benefit plan or
               arrangement, bonus or benefit arrangement, insurance (including
               any self-insurance) or hospitalization program or any other
               fringe or other benefit or compensation plans, programs or
               arrangements for any current or former employee, trustee,
               director, consultant or agent, whether pursuant to contract,
               arrangement, custom or informal understanding, or any other
               "employee benefit plan" (as defined in Section 3(3) of ERISA); or

                    (C) any employment, severance, termination, consultancy or
               other similar agreement.

               (ii) A true and correct copy of each of the plans, programs,
          arrangements, and agreements listed in Section 3.1(l)(i) of the AMLI
          Disclosure Letter (referred to hereinafter as "AMLI Employee Benefit
          Plans") has been supplied to the Purchaser. In the case of any AMLI
          Employee Benefit Plan which is not in written form, the Purchaser has
          been supplied with an accurate description of such AMLI Employee
          Benefit Plan as in effect on the date hereof. A true and correct copy
          of the most recent annual report, actuarial report, accountant's
          opinion of the plan's financial statements, summary plan description
          and Internal Revenue Service determination letter with respect to each
          AMLI Employee Benefit Plan, to the extent applicable, has been
          supplied to the Purchaser, and there have been no material changes in
          the financial condition in the respective plans from that stated in
          the annual reports and actuarial reports supplied. Section 3.1(l)(i)
          of the AMLI Disclosure Letter contains a true and complete list of
          each loan or extension of credit between AMLI or any AMLI Subsidiary,
          on the one hand, and any of their respective trustees, directors,
          officers or employees, on the other, and the outstanding balances
          under each such loan or extension of credit as of the date hereof.

               (iii) As to all AMLI Employee Benefit Plans:

                    (A) All AMLI Employee Benefit Plans comply and have been
               administered in form and in operation in all material respects
               with all


                                      -25-

<PAGE>

               applicable requirements of law, and no event has occurred which
               will or could cause any such AMLI Employee Benefit Plan to fail
               to comply with such requirements and no notice has been issued by
               any governmental authority questioning or challenging such
               compliance.

                    (B) (w) All AMLI Employee Benefit Plans which are employee
               pension benefit plans comply in form and in operation in all
               material respects with all applicable requirements of Sections
               401(a) and 501(a) of the Code; (x) each AMLI Employee Benefit
               Plan which is intended to be qualified under Section 401(a) of
               the Code has received a favorable determination letter, or has
               pending an application for such determination from the Internal
               Revenue Service with respect to those provisions for which the
               remedial amendment period under Section 401(b) of the Code has
               not expired, and AMLI is not aware of any reason why any such
               determination letter should be revoked or not be reissued; (y)
               there have been no amendments to such plans which are not the
               subject of a favorable determination letter issued with respect
               thereto by the Internal Revenue Service (other than an amendment
               for which the remedial amendment period under Section 401(b) of
               the Code has not expired); and (z) no event has occurred which
               could reasonably be expected to give rise to disqualification of
               any such plan under such sections or to a tax under Section 511
               of the Code.

                    (C) Except as set forth in Section 3.1(l)(iii)(C) of the
               AMLI Disclosure Letter, none of the assets of any AMLI Employee
               Benefit Plan is invested in employer securities or employer real
               property.

                    (D) There have been no "prohibited transactions" (as
               described in Section 406 of ERISA or Section 4975 of the Code)
               with respect to any AMLI Employee Benefit Plan.

                    (E) There have been no acts or omissions by which have given
               rise to or which could reasonably be expected to give rise to
               fines, penalties, taxes or related charges under Section 502 of
               ERISA or Chapters 43, 47, 68 or 100 of the Code for which AMLI or
               any AMLI Subsidiary may be liable.

                    (F) Except as set forth in Section 3.1(l)(iii)(F) of the
               AMLI Disclosure Letter, none of the payments contemplated by the
               AMLI Employee Benefit Plans would, in the aggregate, constitute
               excess parachute payments (as defined in Section 280G of the Code
               (without regard to subsection (b)(4) thereof)).

                    (G) There are no actions, suits or claims (other than
               routine claims for benefits) pending or threatened involving any
               AMLI Employee Benefit Plan or the assets thereof and no facts
               exist which could give rise to any such actions, suits or claims
               (other than routine claims for benefits).

                    (H) Neither AMLI, any AMLI Subsidiary nor any of their
               respective ERISA Affiliates sponsors, maintains or contributes
               to, or has in the past six years sponsored, maintained or
               contributed to, any employee benefit plan subject to Title IV of
               ERISA.

                    (I) Each AMLI Employee Benefit Plan which constitutes a
               "group health plan" (as defined in Section 607(1) of ERISA or
               Section 4980B(g)(2) of the Code), including any plans of current
               and former affiliates which must be taken into account under
               Sections 4980B and 414(t) of the Code or Section 601 of ERISA,
               has been operated in compliance in all material respects with
               applicable law, including coverage requirements of Sections 4980B
               of the Code, Chapter 100 of the Code and Section 601 of ERISA to
               the extent such requirements are applicable.

                    (J) Neither AMLI nor any AMLI Subsidiary has any liability
               or contingent liability for providing, under any AMLI Employee
               Benefit Plan or otherwise, any post-retirement medical or life
               insurance benefits, other than statutory liability for providing
               group health plan continuation coverage under Part 6 of Title I
               of ERISA and Section 4980B of the Code.

                    (K) There has been no act or omission that would impair the
               ability of AMLI and AMLI Subsidiaries (or any successor thereto)
               to unilaterally amend or terminate any AMLI Employee Benefit
               Plan.

                    (L) Except as set forth in Section 3.1(l)(iii)(L)(I) of the
               AMLI Disclosure Letter, the consummation of the transactions
               contemplated by this Agreement will not (either alone or together
               with any other event) entitle any current or former employee,
               director, trustee or independent contractor of AMLI or the AMLI
               Subsidiaries to any payment, bonus, retirement, severance, job
               security or similar benefit or enhance any such benefit, or
               accelerate the time of payment, vesting or exercisability or
               trigger any payment of funding (through a grantor trust or
               otherwise) of compensation or benefits under, increase the amount
               payable or trigger any other obligation pursuant to, any AMLI
               Employee Benefit Plan. There is no contract, plan or arrangement
               (written or otherwise) covering any employee or former employee
               of AMLI or any AMLI Subsidiary that, individually or
               collectively, could give rise to the payment of any amount that
               would not be deductible pursuant to Section 162(m) of the Code.
               Section 3.1(l)(i)(iii)(L)(II) of the AMLI Disclosure Letter lists
               all the agreements, arrangements and other instruments which give
               rise to an obligation to make or set aside amounts payable to or
               on behalf of the officers or key employees of the AMLI or the
               AMLI Subsidiaries as a result of the transactions contemplated by
               this Agreement and/or any subsequent employment termination
               (whether by AMLI or the employee), true and complete copies of
               which have been made available to Purchaser prior to the date
               hereof.

                    (M) There has been no amendment to, written interpretation
               or announcement (whether or not written) by AMLI or the AMLI
               Subsidiaries relating to, or change in employee participation or
               coverage under, any AMLI Employee Benefit Plan which would
               increase materially the expense of maintaining such employee plan
               above the level of the expense incurred in respect thereof as of
               the Balance Sheet Date.

               (iv) Neither AMLI, any AMLI Subsidiary nor any of their
          respective ERISA Affiliates, contributes to, has contributed to, or
          has any liability or contingent liability with respect to a
          "multiemployer plan" (as defined in Section 3(37) of ERISA).

          (m) Labor and Employment Matters.

               (i) Except as set forth in Section 3.1(m)(i) of the AMLI
          Disclosure Letter, neither AMLI nor any of the AMLI Subsidiaries is a
          party to any collective bargaining agreement or other labor agreement
          with any labor union or organization. Except as set forth in Section
          3.1(m)(i) of the AMLI Disclosure Letter, to the Knowledge of AMLI,
          there is no question involving current union representation of
          employees of AMLI or any of the AMLI Subsidiaries, nor is there any
          activity by any labor organization (or representative thereof) or
          employee group (or representative thereof) to organize any such
          employees.

               (ii) Except as set forth in Section 3.1(m)(ii) of the AMLI
          Disclosure Letter, there is no complaint, lawsuit or proceeding in any
          forum by or on behalf of any present or former employee, any applicant
          for employment or any classes of the foregoing, alleging breach of any
          express or implied contract of employment, any Law or regulation
          governing employment or the termination thereof, or other
          discriminatory, wrongful or tortious conduct in connection with the
          employment relationship pending, or, to the Knowledge of AMLI,
          threatened against AMLI or any of the AMLI Subsidiaries. AMLI and the
          AMLI Subsidiaries are in compliance in all material respects with all
          applicable Laws relating to the employment of their employees,
          including those relating to wages, hours, collective bargaining,
          unemployment compensation, worker's compensation, equal employment
          opportunity, age and disability discrimination, immigration control,
          employee classification and the payment and withholding of Taxes.

               (iii) There is no strike, slowdown, representation or
          certification campaign or work stoppage or lockout with respect to the
          employees of AMLI or the AMLI Subsidiaries pending, or, to the
          Knowledge of AMLI, threatened, against AMLI or any of the AMLI
          Subsidiaries.

               (iv) There is no proceeding, claim, suit, action or governmental
          investigation pending or, to the Knowledge of AMLI, threatened, with
          respect to which any current or former trustee, director, officer,
          employee or agent of AMLI


                                      -28-

<PAGE>

          or any of the AMLI Subsidiaries is claiming indemnification from AMLI
          or any of the AMLI Subsidiaries.

          (n) Intangible Property.

               (i) Except as, individually or in the aggregate, has not had and
          would not reasonably be expected to have an AMLI Material Adverse
          Effect, there are no valid grounds for any bona fide claims: (i) to
          the effect that the manufacture, sale, licensing or use of any product
          as now used, sold or licensed or proposed for use, sale or license by
          AMLI or any AMLI Subsidiary, infringes on any copyright, patent,
          trademark, trade name, service mark or trade secret of any third
          party; (ii) against the use by AMLI or any AMLI Subsidiary of any
          copyrights, patents, trademarks, trade names, service marks, trade
          secrets, technology, know-how or computer software programs and
          applications used in the business of AMLI or any AMLI Subsidiary as
          currently conducted or as proposed to be conducted, (iii) challenging
          the ownership, validity or effectiveness of any of the AMLI
          Intellectual Property Rights material to AMLI and the AMLI
          Subsidiaries, taken as a whole, or (iv) challenging the license or
          legally enforceable right to use of the Third-Party Intellectual
          Property Rights by AMLI or any AMLI Subsidiary. Except as,
          individually or in the aggregate, has not had and would not reasonably
          be likely to have an AMLI Material Adverse Effect, AMLI and each AMLI
          Subsidiary owns, or is licensed to use (in each case free and clear of
          any Encumbrances), all Intellectual Property currently used in its
          business as presently conducted.

               (ii) As used in this Agreement, the term (i) "Intellectual
          Property" means all patents, trademarks, trade names, service marks,
          copyrights and any applications therefor, technology, know-how,
          computer software programs or applications, and other proprietary
          information or materials, trademarks, trade names, service marks and
          copyrights, (ii) "Third-Party Intellectual Property Rights" means any
          rights to Intellectual Property owned by any third party, and (iii)
          "AMLI Intellectual Property Rights" means the Intellectual Property
          owned or used by AMLI or any AMLI Subsidiary.

          (o) Environmental Matters. Except as described in Section 3.1(o) of
the AMLI Disclosure Letter:

               (i) neither AMLI nor any AMLI Subsidiary is in violation of any
          applicable Law or Order relating to pollution or protection of public
          health and safety, the environment (including indoor or ambient air,
          surface water, groundwater, land surface or subsurface) or natural
          resources, including laws and regulations relating to the release or
          threatened release of any pollutant, contaminant, waste or toxic
          substance, including asbestos or any substance containing asbestos,
          polychlorinated biphenyls and petroleum or petroleum products
          (including crude oil and any fraction thereof) (collectively,
          "Hazardous Materials") or to the manufacture, management, possession,
          presence, generation, processing, distribution, use, treatment,
          storage, disposal, transportation,


                                      -29-

<PAGE>

          abatement, removal, remediation or handling of, or exposure to,
          Hazardous Materials (collectively, "Environmental Laws"), except for
          any violation which, individually or in the aggregate, would not
          constitute an AMLI Material Adverse Effect;

               (ii) in the last three (3) years, neither AMLI nor the AMLI
          Subsidiaries have received any notice of, and there are no pending or,
          to the Knowledge of AMLI, threatened administrative, regulatory or
          judicial actions, suits, demands, demand letters, claims, liens,
          notices of noncompliance or violation, investigation or proceedings
          relating to Hazardous Materials or any Environmental Law against or
          affecting AMLI or any of the AMLI Subsidiaries or any of the AMLI
          Properties (as hereinafter defined);

               (iii) AMLI and the AMLI Subsidiaries have not used, and have not
          permitted the use of, any AMLI Property for activities or operations
          that involve the handling, use, processing, manufacturing, generating,
          producing, storing, refining, recycling, transporting, spilling,
          pumping, pouring, emitting, emptying, discharging, injecting, burying,
          leaching, dumping, disposing of or releasing into the environment or
          otherwise dealing with any Hazardous Material, except for Hazardous
          Materials utilized in the ordinary course of maintaining such real
          properties or utilized in the ordinary course of business of a tenant
          of such AMLI Properties, provided, that such use would not, in the
          ordinary course of business, reasonably be expected to violate
          applicable Environmental Laws; and

               (iv) there is not any seepage, leaking, escaping, leaching,
          discharging, injection, release, emission, spill, pumping, pouring,
          emptying, dumping or other release or threatened release of Hazardous
          Materials into the environment at or from any AMLI Properties,
          including any land or water on, at, under or adjacent to any such AMLI
          Properties, except in accordance with applicable Environmental Laws
          and as would not, individually or in the aggregate, reasonably be
          expected to result in an AMLI Material Adverse Effect.

          (p) Properties.

               (i) Except as listed in Section 3.1(p)(i) of the AMLI Disclosure
          Letter, AMLI LP or an AMLI Subsidiary owns fee simple title to each of
          the real properties identified in Section 3.1(p)(i) of the AMLI
          Disclosure Letter (each property so owned, an "AMLI Property" and
          collectively, the "AMLI Properties"), which are all of the real estate
          properties owned by them, in each case (except as provided below) free
          and clear of liens, mortgages or deeds of trust, claims against title,
          charges which are liens, security interests or other encumbrances on
          title ("Encumbrances"). Except as set forth in Section 3.1(p)(i) of
          the AMLI Disclosure Letter, no other Person has any ownership interest
          in any of the AMLI Properties.

               (ii) The AMLI Properties are not subject to any rights of way,
          restrictive covenants (including deed restrictions or limitations
          issued pursuant to


                                      -30-

          any Environmental Law), declarations, agreements, or Laws affecting
          building use or occupancy, or reservations of an interest in title
          (collectively, "Property Restrictions") or Encumbrances, except for
          (collectively, the "Permitted Title Exceptions") (A) Encumbrances and
          Property Restrictions set forth in Section 3.1(p)(ii) of the AMLI
          Disclosure Letter, (B) Property Restrictions imposed or promulgated by
          Law or any Governmental Entity or included in any AMLI space lease
          with respect to real property, including zoning regulations, provided
          that they do not materially adversely affect the currently intended
          use of any AMLI Property, (C) Encumbrances and Property Restrictions
          disclosed on existing title policies or existing surveys (in either
          case copies of which title policies or surveys have been delivered or
          made available to Purchaser), and (D) mechanics', carriers',
          workmen's, repairmen's and materialmen's liens and other Liens,
          Property Restrictions and other limitations of any kind, if any,
          which, individually or in the aggregate, are not material in amount,
          do not materially detract from the value of or materially interfere
          with the present use of any of the AMLI Properties subject thereto or
          affected thereby, and which, individually or in the aggregate, would
          not be reasonably likely to have an AMLI Material Adverse Effect.

               (iii) Except as provided in Section 3.1(p)(ii) of the AMLI
          Disclosure Letter, (A) AMLI and AMLI LP have made available to
          Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition LP
          all valid policies of title insurance insuring AMLI LP's or the
          applicable AMLI Subsidiary's fee simple title to the AMLI Properties
          and such policies are, at the date hereof, in full force and effect
          and no material claim has been made against any such policy; and (B)
          AMLI and AMLI LP have previously provided or made available to
          Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition LP
          all existing surveys of the AMLI Properties in its possession.

               (iv) Except as set forth in Section 3.1(p)(iv) to the AMLI
          Disclosure Letter, (A) no certificate, permit or license from any
          Governmental Entity having jurisdiction over any of the AMLI
          Properties or any agreement, easement or other right that is necessary
          to permit the lawful use and operation of the buildings and
          improvements on any of the AMLI Properties or that is necessary to
          permit the lawful use and operation of all driveways, roads and other
          means of egress and ingress to and from any of the AMLI Properties has
          not been obtained and is not in full force and effect, except for such
          failures to obtain and to have in full force and effect, which would
          not, individually or in the aggregate, reasonably be likely to have an
          AMLI Material Adverse Effect and (B) neither AMLI nor any AMLI
          Subsidiary has received written notice of any violation of any
          federal, state or municipal law, ordinance, order, regulation or
          requirement affecting any of the AMLI Properties issued by any
          Governmental Authority which have not been cured, contested in good
          faith or which violations would not, individually or in the aggregate,
          reasonably be likely to have an AMLI Material Adverse Effect.

               (v) Except as set forth in Section 3.1(p)(v) to the AMLI
          Disclosure Letter, to AMLI's and AMLI LP's Knowledge, neither AMLI nor
          any AMLI Subsidiary has received any written notice to the effect that
          (A) any condemnation


                                      -31-

<PAGE>

          or rezoning proceedings are pending or threatened with respect to any
          of the AMLI Properties, or (B) any Laws including, without limitation,
          any zoning regulation or ordinance (including with respect to
          parking), board of fire underwriters rules, building, fire, health or
          similar law, code, ordinance, order or regulation has been violated
          for any AMLI Property, which in the case of clauses (A) and (B) above,
          would reasonably be likely to have, individually or in the aggregate,
          an AMLI Material Adverse Effect.

               (vi) Except as set forth in Section 3.1(p)(vi) of the AMLI
          Disclosure Letter, all work required to be performed, payments
          required to be made and actions required to be taken prior to the date
          hereof pursuant to any agreement entered into with a Governmental
          Entity in connection with a site approval, zoning reclassification or
          other similar action relating to any AMLI Properties (e.g., local
          improvement district, road improvement district, environmental
          mitigation) have been performed, paid or taken, as the case may be,
          other than those actions, individually or in the aggregate, the
          failure of which would not reasonably be likely to have an AMLI
          Material Adverse Effect.

               (vii) Section 3.1(p)(vii) of the AMLI Disclosure Letter lists
          each ground lease to which AMLI or any AMLI Subsidiary is party, as
          lessee, and each master lease to which AMLI or any AMLI Subsidiary is
          a lessor. Each such ground lease or master lease is in full force and
          effect and is valid, binding and enforceable, to the Knowledge of
          AMLI, in accordance with its terms against the lessor or lessee
          thereunder, as applicable, except as would not have, or would not
          reasonably be likely to have, individually or in the aggregate, a
          material adverse effect on AMLI's interest in the applicable AMLI
          Property. Except as listed in Section 3.1(p)(vii) of the AMLI
          Disclosure Letter or which would not have, or would not reasonably be
          likely to have, individually or in the aggregate, an AMLI Material
          Adverse Effect, neither AMLI nor any AMLI Subsidiary, on the one hand,
          nor, to the Knowledge of AMLI, any other party, on the other hand, is
          in monetary default under any such ground lease or master lease. No
          option has been exercised under any of such ground leases or master
          leases, except options whose exercise has been evidenced by a written
          document as described in Section 3.1(p)(vii) of the AMLI Disclosure
          Letter. AMLI and AMLI LP have made available to Purchaser, Purchaser
          Acquisition Entity and Purchaser Acquisition LP a correct and complete
          copy of each such ground lease and master lease and all material
          amendments thereto.

               (viii) Except as set forth in Section 3.1(p)(viii) of the AMLI
          Disclosure Letter, neither AMLI nor any AMLI Subsidiary has granted
          any unexpired option agreements, rights of first offer, rights of
          first negotiation or rights of first refusal with respect to the
          purchase of an AMLI Property or any portion thereof or any other
          unexpired rights in favor of third Persons to purchase or otherwise
          acquire an AMLI Property or any portion thereof or entered into any
          contract for sale, ground lease or letter of intent to sell or ground
          lease any AMLI Property or any portion thereof.

               (ix) Except as set forth in Section 3.1(p)(ix) of the AMLI
          Disclosure Letter, neither AMLI nor any AMLI Subsidiary is a party to
          any agreement relating to the management of any of the AMLI Properties
          by a party other than AMLI or any wholly owned AMLI Subsidiaries.

               (x) Except as set forth in Section 3.1(p)(x) of the AMLI
          Disclosure Letter, there is no material renovation or construction
          project with aggregate projected costs in excess of $5,000,000
          currently being performed at any of the AMLI Properties, except for
          the projects set forth in Section 3.1(p)(x) of the AMLI Disclosure
          Letter (the "Construction Projects"). Section 3.1(p)(x) of the AMLI
          Disclosure Letter sets forth the budgeted cost, the cost to complete
          and each Material Contract for each Construction Project. Neither AMLI
          nor any AMLI Subsidiary is in material default of any material
          obligation with respect to the Construction Projects and, to the
          Knowledge of AMLI, the contractors obligated to complete any of the
          Construction Projects are not in material default with respect to such
          obligations as of the date of this Agreement.

               (xi) Except as set forth in Section 3.1(p)(xi) of the AMLI
          Disclosure Letter, none of the material personal property necessary
          for the use, operation, repair or maintenance of any AMLI Property as
          currently used, operated, maintained and repaired is leased from or
          otherwise owned by third parties, except (A) for equipment owned or
          leased by third party vendors providing maintenance or repair services
          to an AMLI Property or (B) for leases, the expense for which is
          included in AMLI's financial statements.

               (xii) There (i) are no material structural defects relating to
          any of the AMLI Properties, (ii) is no AMLI Property whose building
          systems are not in working order in any material respect, and (iii) is
          no physical material damage to any AMLI Property for which there is no
          insurance in effect, which, in the case of any of (i), (ii) or (iii),
          would, individually or in the aggregate, have an AMLI Material Adverse
          Effect.

          (q) Insurance. AMLI or AMLI LP maintains insurance coverage with
reputable insurers, or maintains self-insurance practices, in such amounts and
covering such risks as are in accordance with normal industry practice for
companies engaged in businesses similar to that of AMLI and AMLI LP. Section
3.1(q) of the AMLI Disclosure Letter sets forth a list that is true and complete
in all material respects of all material insurance policies in force naming
AMLI, any AMLI Subsidiary or any employees thereof as an insured or beneficiary
or as a loss payable payee or for which AMLI or any AMLI Subsidiary has paid or
is obligated to pay all or part of the premiums. There is no claim by AMLI or
any AMLI Subsidiary pending under any such policies which (A) has been denied or
disputed by the insurer and (B) would reasonably be likely to have, individually
or in the aggregate, an AMLI Material Adverse Effect. All such insurance
policies are in full force and effect, all premiums due and payable thereon have
been paid, and no written notice of cancellation or termination has been
received by AMLI or AMLI LP with respect to any such policy which has not been
replaced on substantially similar terms prior to the date of such cancellation.

          (r) Opinion of Financial Advisor. The AMLI Board of Trustees has
received the Fairness Opinion to the effect that, based on, and subject to the
various assumptions and qualifications set forth in the Fairness Opinion, as of
the date of the Fairness Opinion, (i) the consideration to be received by the
AMLI Common Shareholders in the Merger is fair from a financial point of view to
such holders and (ii) the consideration to be received by the AMLI LP
Unitholders is fair from a financial point of view to such holders considered as
if such LP Units had been converted into or redeemed for AMLI Common Shares in
accordance with the existing terms of LP Units.

          (s) Vote Required. The affirmative vote of the holders of AMLI Common
Shares casting at least two-thirds of the votes entitled to be cast (the "AMLI
Shareholder Approval") is the only vote of the holders of any class or series of
the AMLI Common Shares or other securities of or equity interests in AMLI or
AMLI LP required to approve this Agreement and to approve and consummate the
Mergers and the other transactions contemplated by the Transaction Documents.

          (t) Brokers. Except for the fees and expenses payable to the AMLI
Financial Advisor pursuant to the engagement letter set forth in Section 3.1(t)
of the AMLI Disclosure Letter, no broker, investment banker or other Person is
entitled to any broker's, finder's or other similar fee or commission in
connection with the transactions contemplated by the Transaction Documents based
upon arrangements made by or on behalf of AMLI, any AMLI Subsidiary or any
Affiliate thereof.

          forth in the AMLI annual report of Form 10-K for the year ended
          December 31, 2004. AMLI has, prior to the date hereof, made available
          to Purchaser (including by filing with the SEC) true and complete

          Except as set forth in Section 3.1(u)(i) of the AMLI Disclosure
          Letter, all Material Contracts are valid, binding and enforceable and
          in full force and effect with respect to AMLI and the AMLI
          Subsidiaries, and to the Knowledge of AMLI, with respect to each other
          party to any such Material Contract, except where such failure to be
          so valid, binding and enforceable and in full force and effect do not
          and would not, individually or in the aggregate, constitute an AMLI
          Material Adverse Effect, and except, in each case, to the extent that
          enforcement of rights and remedies created by any Material Contracts
          are subject to bankruptcy, insolvency, fraudulent transfer,
          reorganization, moratorium and similar Laws of general application
          related to or affecting creditors' rights and to general equity
          principles. Except as set forth in Section 3.1(u)(i) of the AMLI
          Disclosure Letter, (i) neither AMLI nor any AMLI Subsidiary is in

          which it is a party or by which it or any of its properties or assets
          is bound and, (ii) to the Knowledge of AMLI there are no such
          violations or defaults (nor does there exist any condition

          any Material Contract, except in either the case of clause (i) or (ii)
          for those violations or defaults that, individually or in the
          aggregate, would not reasonably be likely to have an AMLI Material
          Adverse Effect. For purposes of this Agreement, "Material Contracts"
          shall mean (i) any loan agreement, letter of credit, indenture, note,
          bond, debenture, mortgage or any other document, agreement or

          of Federal Regulations, (iv) any interest rate cap, interest rate
          collar, interest rate swap, currency hedging transaction and any other
          agreement relating to a similar transaction to which AMLI or any AMLI
          Subsidiary is a party or an obligor with respect thereto (v) any
          agreement in which the amount involved exceeds $60,000 per annum with
          any trustee, director or employee of AMLI or the AMLI Subsidiaries
          earning in excess of $75,000 per annum in base compensation and cash
          bonus or with any "associate" or any member of the "immediate family"
          (as such terms are respectively defined in Rules 12b-2 and 16a-1 of
          the 1934 Act) of any such trustee, director or employee; (vi) any
          partnership or joint venture agreement with any third parties; and

               (ii) Except as set forth in Section 3.1(u)(ii) of the AMLI
          Disclosure Letter, there is no confidentiality agreement,
          non-competition agreement or other contract or agreement that contains
          covenants that restrict AMLI's ability to compete in any line of
          business or with any Person in any geographical area.

               (iii) Except as set forth in Section 3.1(u)(iii) of the AMLI
          Disclosure Letter, there are no indemnification agreements entered
          into by and between AMLI and any trustee, director or officer of AMLI
          or any of the AMLI Subsidiaries.

               (iv) None of AMLI or any AMLI Subsidiary is a party to any

          provides services with respect to any real properties other than AMLI
          Properties, except for the agreements listed in Section 3.1(u)(iv) of
          the AMLI Disclosure Letter.

               (v) Section 3.1(u)(v) of the AMLI Disclosure Letter lists all
          agreements entered into by AMLI or any AMLI Subsidiary providing for

<PAGE>

          of, or option to sell, any AMLI Properties or the purchase of, or
          option to purchase, by AMLI or any AMLI Subsidiary, on the one hand,

necessary actions to exempt the Merger, the Partnership Merger, the Transaction
Documents and the other transactions contemplated thereby from the restrictions
of Subtitles 6 and 7 of Title 3 of the MGCL and Title 8 (collectively, the
"Takeover Statute"). No other "control share acquisition," "fair price,"
"moratorium" or other antitakeover Laws apply to the Merger, the Partnership
Merger, the Transaction Documents or the other transactions contemplated
thereby. AMLI and the AMLI Board of Trustees have taken all appropriate and
necessary actions to (A) render the rights under the AMLI Rights Agreement
inapplicable in the Merger, the Partnership Merger, the Transaction Documents
and the other transactions contemplated thereby, (B) cause the Merger, the
Partnership Merger, the Transaction Documents and the other transactions
contemplated hereby to comply with or be exempted from any provision contained
in the AMLI Charter, AMLI Bylaws or in the comparable organizational document of
any AMLI Subsidiary that would otherwise prohibit, hinder or delay such
transactions and (C) render any and all limitations on ownership of (1) AMLI
Common Shares as set forth in the AMLI Charter and (2) the limited partner
interests in AMLI LP as set forth in the AMLI LP Agreement, including the
ownership limit (the "Ownership Limit") set forth in the AMLI Charter
inapplicable to the Merger, Partnership Merger, the Transaction Documents and
the other transactions contemplated thereby.

          (w) Related Party Transactions. Except as described in the AMLI SEC
Documents filed prior to the date hereof or as set forth in Section 3.1(w) of
the AMLI Disclosure Letter, there are no material arrangements, agreements or
contracts which continue in effect as of the date hereof entered into by AMLI or
any of the AMLI Subsidiaries, on the one hand, and any Person who is an officer,
trustee, director or affiliate of AMLI or any AMLI Subsidiary, any relative of
the foregoing or an entity of which any of the foregoing is an Affiliate, on the
other hand. True and complete copies of all such documents have been made
available to Purchaser prior to the date hereof.

          (x) Investment Company Act of 1940. Neither AMLI, AMLI LP nor any of
the other AMLI Subsidiaries is, or at the Merger Effective Time or the
Partnership Merger Effective Time will be, required to be registered as an
investment company under the Investment Company Act of 1940, as amended.

          (y) Information Supplied. The information supplied by AMLI or any AMLI
Subsidiary for inclusion in the Proxy, or any amendment or supplement thereto,
shall not, on the date the Proxy is first mailed to AMLI Common Shareholders, at
the time of the AMLI Shareholder Approval or at the Effective Time, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.

The Proxy Statement, and any supplement or amendment thereto, shall comply in
all material respects with all applicable requirements of Law. AMLI shall date
the Proxy Statement as of the approximate date of mailing to its shareholders
and shall use its commercially reasonable efforts to cause the Proxy Statement

the Proxy Statement, (i) Purchaser or AMLI, as the case may be, shall promptly
inform the other of such occurrences, (ii) AMLI shall prepare and file with the
SEC any such amendment or supplement to the Proxy Statement; provided, however,
that no amendment or supplement to the Proxy Statement will be made without
prior consultation with Purchaser and providing Purchaser a reasonable
opportunity to review and comment on such amendment or supplement, (iii) AMLI
shall use its commercially reasonable efforts to have any such amendment or
supplement cleared for mailing, to the extent necessary, to AMLI shareholders as
promptly as practicable after such filing and (iv) AMLI shall use its
commercially reasonable efforts to have any such amendment or supplement mailed

following the date the Proxy Statement is mailed to its shareholders), for the
purpose of obtaining the AMLI Shareholder Approval. AMLI will, through the AMLI
Board of Trustees, recommend to its shareholders approval of the Merger and the
other transactions contemplated hereby and further covenants that the Proxy
Statement will include such recommendation (the "AMLI Recommendation") except to
the extent that the AMLI Board of Trustees shall have withdrawn such
recommendation in accordance with Section 5.6 hereof.

          (c) If on the date of the AMLI Shareholders Meeting or any subsequent
adjournment thereof pursuant to this Section 5.1(c), AMLI has not received
proxies representing a sufficient number of AMLI Common Shares to approve the

be mutually agreed upon by AMLI and Purchaser, which date shall not be less than
ten days nor more than 20 days after the date of adjournment, and shall continue

officers, employees, accountants, counsel, financial advisors and other
representatives to cooperate reasonably with Purchaser in its investigation of
the business of AMLI, AMLI LP and the other AMLI Subsidiaries. Notwithstanding
the foregoing, AMLI shall not be required by this Section 5.2 to provide
Purchaser, Purchaser Acquisition Entity, Purchaser Acquisition LP or their
respective representatives with access to the properties of AMLI or any AMLI
Subsidiary for the purpose of invasive physical testing; provided, that, in the
case of AMLI Properties that are wholly-owned by an AMLI Subsidiary, neither
AMLI nor any AMLI Subsidiary shall unreasonably withhold consent for such access
and testing if Purchaser determines in good faith, after the date hereof, that
there is a reasonable likelihood that a significant environmental Liability
exists with respect to such property. Each of Purchaser, Purchaser Acquisition
Entity and Purchaser Acquisition LP will hold, and will cause its respective
officers, employees, accountants, counsel, financial advisors and other
representatives and Affiliates to hold, any nonpublic information in confidence
to the extent required by, and in accordance with, and will comply with the

Acquisition Entity, Purchaser Acquisition LP, AMLI and AMLI LP shall take all
such necessary action. From the date of this Agreement through the Merger
Effective Time, AMLI shall timely file, or cause to be filed, with the SEC all

and provide Purchaser a reasonable opportunity to review and comment on all

Purchaser Subsidiaries taken as a whole.

          (c) AMLI and AMLI LP shall give prompt notice to Purchaser, and
Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition LP shall give
prompt notice to AMLI and AMLI LP, if (i) any representation or warranty made by
it contained in this Agreement that is qualified as to materiality becomes
untrue or inaccurate in any respect or any such representation or warranty that
is not so qualified becomes untrue or inaccurate in any material respect or (ii)
it fails to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

     Section 5.4 Tax Matters.

          (a) Purchaser, Purchaser Acquisition Entity, Purchaser Acquisition LP,
AMLI and AMLI LP shall report the portions of the transactions contemplated
hereby consisting of the Merger in accordance with the treatment contemplated by
Section 2.1(d) and each shall use its respective best efforts to cause such
portions of such transactions to be so treated for U.S. federal income tax
purposes.

          (b) Unless required by Law (as evidenced by the legal opinion of a
nationally recognized U.S. law firm reasonably acceptable to Purchaser and
AMLI), neither Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition
LP, on the one hand, nor AMLI and AMLI LP, on the other hand, will take or omit
to take any action, or permit any status to exist, prior to the Merger Effective
Time, that would or may jeopardize, or that is inconsistent with, AMLI's (or any
AMLI Subsidiary that files a REIT tax Return) status as a REIT under the Code or
the status of AMLI LP or any AMLI Subsidiary organized and existing as a
partnership or limited liability company under the Laws of its jurisdiction of
organization (a "AMLI Subsidiary Partnership") as a partnership for purposes of
Taxes for any period.

          (c) The Merger Consideration (including assumed liabilities) shall be
allocated among AMLI's assets in accordance with Section 1060 of the Code. The
parties shall work in good faith to agree on such allocation prior to the
Closing Date. Following the Merger, the Surviving Entity in connection with its
U.S. federal, state, and local tax returns and other filings (including without
limitation Internal Revenue Service Form 8594), shall not take any position
inconsistent with such allocation. Any adjustment to the purchase price shall be
allocated as provided by Treas. Reg. Section 1.1060-1(c).

          (d) Nothing in this Section 5.4 shall be construed to limit the
ability of Purchaser or its Affiliates from causing AMLI to seek a "closing
agreement" within the meaning of Section 7121 of the Code if it is reasonably
determined that AMLI or an AMLI Subsidiary engaged in any action or failed to
take any action that jeopardized the status of AMLI (or of any AMLI Subsidiary
that is a REIT) as a REIT prior to the Merger Effective Time.

<PAGE>

          (e) Within 90 days after the Closing, Purchaser Acquisition Corp.
shall deliver to AMLI a schedule allocating the Purchase Price (including
assumed liabilities) among the assets of AMLI in accordance with Section 1060 of
the Code and the regulations thereunder. The parties agree not to take any
position inconsistent with the Allocation Schedule for Tax reporting purposes.

          (f) Unless prohibited by Law (as evidenced by the legal opinion of a
nationally recognized U.S. law firm reasonably acceptable to Purchaser and AMLI)
or this Agreement, up to the Merger Effective Time, AMLI, each AMLI Subsidiary
and any Affiliate of any of them, shall be permitted to take or omit to take any
action required to maintain AMLI's status as a REIT under the Code or the status
of AMLI LP or any AMLI Subsidiary Partnership as a partnership for purposes of
Taxes for any period. AMLI shall provide Purchaser with prior written notice of
its intention to take any such action or to omit to take any such action outside
the ordinary course of business, and shall consult with Purchaser in good faith
with respect to such action or omission.

          (g) AMLI shall provide to Purchaser copies of Tax Returns that are to
be filed on or prior to the Partnership Merger Effective Time at least five (5)
calendar days prior to the due date of such returns (including applicable
extensions), and AMLI shall consider in good faith any and all reasonable
comments of Purchaser with respect to such Tax Returns.

          (h) AMLI shall use its reasonable best efforts to obtain the tax
opinion described in Section 6.2(e) dated as of the Closing Date.

     Section 5.5 No Solicitation of Transactions.

          (a) Subject to Section 5.6, none of AMLI, AMLI LP or any other AMLI
Subsidiary shall, nor shall it authorize or permit, directly or indirectly, any
officer, trustee, director, employee, agent, investment banker, financial
advisor, attorney, accountant, broker, finder or other agent, representative or
Affiliate of AMLI, AMLI LP or any other AMLI Subsidiary to initiate, solicit,
encourage or facilitate (including by way of furnishing nonpublic information or
assistance) any inquiries or the making of any proposal or other action that
constitutes, or may reasonably be expected to lead to, any Competing Transaction
(as defined herein), enter into discussions or negotiate with any Person in
furtherance of such inquiries or to obtain a Competing Transaction or release
any Person from any standstill agreement or similar obligation to AMLI or any
AMLI Subsidiary other than the automatic termination of standstill obligations
pursuant to the terms of agreements as in effect as of the date hereof, by
virtue of the execution and announcement of this Agreement. AMLI and AMLI LP
shall, and shall cause the other AMLI Subsidiaries, and AMLI, AMLI LP and the
other AMLI Subsidiaries shall, take all actions reasonably necessary to cause
their respective officers, trustees, directors, employees, investment bankers,
financial advisors, attorneys, accountants, brokers, finders and any other
agents, representatives or Affiliates to, immediately cease any discussions,
negotiations or communications with any party or parties with respect to any
Competing Transaction. AMLI, AMLI LP and the AMLI Subsidiaries shall be
responsible for any failure on the part of their respective officers, trustees,
directors, employees, investment bankers, financial advisors, attorneys,
accountants, brokers, finders and any other agents, representatives or
Affiliates to comply with this Section 5.5(a). AMLI and AMLI LP shall promptly
request each person that


                                      -49-

<PAGE>

has heretofore executed a confidentiality agreement in connection with its
consideration of acquiring (whether by merger, acquisition, stock sale, asset
sale or otherwise) AMLI, AMLI LP or any other AMLI Subsidiary, or any material
position of their assets, if any, to return all confidential information
heretofore furnished to such person by or on behalf of AMLI, AMLI LP or any
other AMLI Subsidiary.

          (b) AMLI and AMLI LP shall notify Purchaser promptly following receipt
of (but in any event within 24 hours after the Chief Executive Officer of AMLI
has received) the relevant details relating to any inquiry or proposal
(including the identity of the parties, price and other terms thereof) which any
of AMLI, AMLI LP or any of the other AMLI Subsidiaries or any such officer,
trustee, director, employee, agent, investment banker, financial advisor,
attorney, accountant, broker, finder or other representative or Affiliate may
receive after the date hereof relating to any of the matters described in
Section 5.5(a) and shall keep Purchaser reasonably informed on a current basis
as to the status of and any material developments regarding any such inquiry or
proposal.

          (c) For purposes of this Agreement, a "Competing Transaction" shall
mean any of the following (other than the transactions expressly provided for in
this Agreement): (i) any merger, consolidation, share exchange, business
combination or similar transaction involving AMLI or AMLI LP (or any of the
other AMLI Subsidiaries); (ii) any sale, lease, exchange, mortgage, pledge,
transfer or other disposition of 30% or more of the assets (including by means
of an issuance, sale or other disposition of voting securities) of AMLI and the
AMLI Subsidiaries, taken as a whole, or of 30% or more of any class of voting
securities of AMLI, in a single transaction or series of related transactions,
excluding any bona fide financing transactions which do not, individually or in
the aggregate, have as a purpose or effect the sale or transfer of control of
such assets; or (iii) any tender offer or exchange offer for 30% or more of any
class of voting securities of AMLI (or any of the AMLI Subsidiaries).

          (d) For purposes of this Agreement, a "Superior Competing Transaction"
means a bona fide, unsolicited, written proposal for a Competing Transaction
made by a third party which the AMLI Board of Trustees determines (after taking
into account any amendments to this Agreement, the other Transaction Documents
or the transactions contemplated hereby or thereby proposed by Purchaser), in
good faith and after consultation with its financial and legal advisors, is on
terms which are more favorable from a financial point of view (including
financing terms, any termination fee or expense reimbursement payable under this
Agreement, any conditions to the consummation thereof and the likelihood of the
Competing Transaction proposal being consummated) to the AMLI Common
Shareholders than the Mergers and the other transactions contemplated by this
Agreement.

     Section 5.6 Board Actions.

          (a) Notwithstanding Section 5.5 or any other provision of this
Agreement to the contrary, following the receipt by AMLI of a proposal from a
third party for a Competing Transaction (that was not solicited, encouraged or
facilitated in violation of Section 5.5) the Board of Trustees may (I) contact
such Person and its advisors solely for the purpose of clarifying the proposal
and any material contingencies and the capability of consummation, so as to
determine whether the proposal for a Competing Transaction is reasonably likely
to lead to a


                                      -50-

<PAGE>

Superior Competing Transaction and (II) if the Board of Trustees determines in
good faith following consultation with its legal and financial advisors that
such proposal for a Competing Transaction is reasonably likely to lead to a
Superior Competing Transaction, the AMLI Board of Trustees may (directly or
through advisors or representatives) (i) furnish non-public information with
respect to AMLI and the AMLI Subsidiaries to the Person who made such proposal
(provided that AMLI (A) has previously or concurrently furnished such
information to Purchaser, (B) shall furnish such information pursuant to a
confidentiality agreement which is at least as favorable to AMLI as the
Confidentiality Agreement and (C) shall notify Purchaser in writing prior to
providing any such information), (ii) disclose to its shareholders any
information required to be disclosed under applicable Law, (iii) participate in
negotiations regarding such proposal and (iv) following receipt of a proposal
for a Competing Transaction that constitutes a Superior Competing Transaction,
but prior to the AMLI Shareholder Approval, (A) withdraw or modify in a manner
adverse to Purchaser, or fail to make, the AMLI Recommendation or recommend that
AMLI Common Shareholders approve such Superior Competing Transaction, (B)
terminate this Agreement pursuant to, and subject to compliance with, Section
7.1(g) or (C) take any action that any court of competent jurisdiction orders
AMLI to take, but in each case referred to in clauses (i) through (iv) only if,
after complying with Section 5.6(b), the AMLI Board of Trustees determines in
good faith, after consultation with its outside legal counsel, that failure to
take such action would be inconsistent with its duties to AMLI or its
shareholders under applicable Law. Nothing in this Section 5.6 shall prevent the
AMLI Board of Trustees from complying with Rule 14e-2(a) promulgated under the
Exchange Act with respect to a Competing Transaction; provided, however, that
neither AMLI nor the AMLI Board of Trustees shall be permitted to recommend
pursuant to such provision a Competing Transaction which is not a Superior
Competing Transaction.

          (b) The AMLI Board of Trustees shall not take any of the actions
referred to in clauses (i) through (iv) of Section 5.6(a) unless not fewer than
three Business Days prior to taking any such action, AMLI shall have, during
such three Business Day period, negotiated in good faith with Purchaser
concerning any proposed amendments to this Agreement, the other Transaction
Documents or the transactions contemplated hereby or thereby.

     Section 5.7 Public Announcements. AMLI, AMLI LP and Purchaser shall consult
with each other before issuing any press release or otherwise making any public
statements or filings with respect to this Agreement or any other Transaction
Document or any of the transactions contemplated hereby or thereby and shall not
issue any such press release or make any such public statement or filing without
the prior consent of the other party, which consent shall not be unreasonably
withheld or delayed; provided, however, that a party may, without the prior
consent of the other party, issue such press release or make such public
statement or filing as may be required by Law or the applicable rules of any
stock exchange if it has used its commercially reasonable efforts to consult
with the other party and to obtain such party's consent but has been unable to
do so prior to the time such press release or public statement or filing is
required to be released, filed or furnished pursuant to such Law or rules. In
this regard, the parties shall make a joint public announcement of the
transactions contemplated by the Transaction Documents no later than (i) the
close of trading on the New York Stock Exchange on the day this Agreement is
signed, if such signing occurs during regular business hours on a Business Day
or (ii) the opening of trading on the New York Stock Exchange on the next


                                      -51-

<PAGE>

Business Day following the date on which this Agreement is signed, if such
signing does not occur during regular business hours on a Business Day.

     Section 5.8 Employee Arrangements.

          (a) AMLI Severance Plan and AMLI Severance Agreements. On, or as soon
as reasonably practicable after, the Closing Date, Purchaser shall pay or cause
to be paid the amounts due to such of AMLI's senior executive officers under
such senior executive officers' employment agreements, which agreements are set
forth in Section 5.8(a) of the AMLI Disclosure Letter. On and after the Closing
Date, Purchaser shall cause the Surviving Entity to pay the employees of AMLI
and all AMLI Subsidiaries (collectively, the "AMLI Employees") any severance
payments owed to any such AMLI Employees under any AMLI Severance Plan.

          (b) AMLI Options. AMLI and each AMLI Subsidiary shall take all actions
as may be necessary under the AMLI Option Plan to effect the cancellations
described in Section 1.8. In addition to the foregoing and subject to the terms
of the AMLI Option Plan and applicable Law, AMLI shall take all actions
necessary to cause the AMLI Option Plan to be terminated at or prior to the
Merger Effective Time, and to satisfy Purchaser that no holder of AMLI Options
or other awards under such plans or programs or participant in the AMLI Option
Plan, will have any right to acquire any interest in the Surviving Entity,
Purchaser or any Purchaser Subsidiary, including Purchaser Acquisition Entity,
as a result of the exercise of AMLI Options or other awards or rights pursuant
to such AMLI Option Plan at or after the Merger Effective Time.

          (c) AMLI Bonuses. AMLI shall be permitted to pay the bonuses
identified on Section 4.1(b)(xiv) of the AMLI Disclosure Letter at such time or
times as identified on Section 4.1(b)(xiv) of the AMLI Disclosure Letter.

          (d) Continuing Benefits and Compensation. For a period of not less
than one year commencing immediately following the Merger Effective Time,
Purchaser shall, or cause the Surviving Entity to, provide to each AMLI employee
who remains employed by the Purchaser, the Surviving Entity or the Surviving
Partnership after the Merger Effective Time compensation and employee benefits
(other than equity-based compensation) that are substantially comparable in the
aggregate to the compensation and AMLI employee benefits (other than
equity-based compensation, retention, sale, stay, special bonus or other change
in control payments or awards) provided immediately before the Merger Effective
Time.

     Section 5.9 Indemnification; Trustees' and Officers' Insurance.

          (a) In the event of any threatened or actual claim, action, suit,
demand, proceeding or investigation, whether civil, criminal or administrative,
including, without limitation, any such claim, action, suit, proceeding or
investigation in which any person who is now, or has been at any time prior to
the date hereof, or who becomes prior to the Merger Effective Time, a trustee,
director or officer of AMLI or any of the AMLI Subsidiaries (each, an
"Indemnified Party" and collectively, the "Indemnified Parties") is, or is
threatened to be, made a party based in whole or in part on, or arising in whole
or in part out of, or pertaining to (i) the fact that he or she is or was a
trustee, director, officer, employee, or agent of AMLI or any of the


                                      -52-

<PAGE>

AMLI Subsidiaries, or is or was serving at the request of AMLI or any of the
AMLI Subsidiaries as a trustee, director, officer, employee, or agent of another
corporation, partnership, joint venture, trust or other enterprise, in each case
at or prior to the Merger Effective Time or (ii) the negotiation, execution or
performance of this Agreement, any agreement or document contemplated hereby or
delivered in connection herewith, or any of the transactions contemplated hereby
AMLI shall indemnify and hold harmless, and after the Merger Effective Time, the
Surviving Entity (together with AMLI, the "Indemnitors"), shall indemnify and
hold harmless, as and to the fullest extent that a Maryland corporation is
permitted under applicable Law to indemnify its own officers and directors, each
Indemnified Party against any losses, claims, damages, liabilities, costs,
expenses (including reasonable attorneys' fees and expenses), judgments, fines
and amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, demand, proceeding or investigation (collectively,
"Indemnifiable Amounts"), and in the event of any such threatened or actual
claim, action, suit, proceeding or investigation (whether asserted before or
after the Merger Effective Time), (A) the Indemnitors, shall promptly (but in
any event within 10 calendar days of written request) advance expenses pending
the final disposition of any such threatened or actual claim, action, suit,
demand, proceeding or investigation to each Indemnified Party to the fullest
extent permitted by applicable Law; (B) the Indemnitors shall have the right to
defend each Indemnified Party in any proceeding which may give rise to the
payment of Indemnifiable Amounts hereunder; provided, however, that the
Indemnitors shall notify such Indemnified Party of any such decision to defend
within ten (10) calendar days of receipt of written notice of any such
proceeding, and, provided further, that the Indemnitors shall not, without the
prior written consent of such Indemnified Party, consent to the entry of any
judgment against such Indemnified Party or enter into any settlement or
compromise which (I) includes an admission of fault of such Indemnified Party or
(II) does not include, as an unconditional term thereof, the full release of
such Indemnified Party from all liability in respect of such proceeding, which
release shall be in form and substance reasonably satisfactory to such
Indemnified Party and (C) notwithstanding clause (B) above, if in a proceeding
to which an Indemnified Party is a party by reason of the Indemnified Party's
service as a trustee, director, officer, employee, or agent of AMLI or any of
the AMLI Subsidiaries, (I) such Indemnified Party reasonably concludes that he
or she may have separate defenses or counterclaims to assert with respect to any
issue which may not be consistent with the position of other defendants in such
proceeding, (II) a conflict of interest or potential conflict of interest exists
between such Indemnified Party and the Indemnitors, or (III) if the Indemnitors
fail to assume the defense of such proceeding in a timely manner, such
Indemnified Party shall be entitled to be represented by separate legal counsel
of such Indemnified Party's choice at the expense of the Indemnitors; provided,
however, that none of the Indemnitors shall be liable for any settlement
effected without its prior written consent (which consent shall not be
unreasonably withheld, conditioned or delayed); and provided further that the
Indemnitors shall have no obligation hereunder to any Indemnified Party when and
if a court of competent jurisdiction shall have ultimately determined, and such
determination shall have become final and non-appealable, that indemnification
by such entities of such Indemnified Party in the manner contemplated hereby is
prohibited by applicable Law. Any Indemnified Party wishing to claim
indemnification under this Section 5.9, upon learning of any such threatened or
actual claim, action, suit, demand, proceeding or investigation, shall promptly
notify AMLI and, after the Merger Effective Time, the Surviving Entity, thereof;
provided that the failure to so notify shall not affect the obligations


                                      -53-

<PAGE>

of AMLI and the Surviving Entity except to the extent, if any, such failure to
promptly notify materially and adversely prejudices such party.

          (b) Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition
LP agree that all rights to indemnification existing in favor of, and all
exculpations and limitations of the personal liability of, the Indemnified
Parties provided for in the AMLI Charter or the AMLI Bylaws, as well as
indemnification agreements, as in effect as of the date hereof and listed in
Section 5.9 of the AMLI Disclosure Letter with respect to matters occurring at
or prior to the Merger Effective Time, including the Merger, shall continue in
full force and effect in accordance with their terms. For a period of six (6)
years after the Merger Effective Time, the Surviving Entity shall, and Purchaser
will cause the Surviving Entity to, cause to be maintained in effect, with
respect to actions and omissions occurring at or prior to the Merger Effective
Time, trustees', directors' and officers' liability insurance and fiduciary
insurance policies of not less than the existing coverage under, and having
other terms not less favorable to, the insured persons than the trustees',
directors' and officers' liability insurance coverage presently maintained by
AMLI; provided that, in satisfying such obligation, none of the Purchaser or any
Purchaser Subsidiary shall be obligated to pay premiums per annum in excess of
250% of the aggregate amount per annum that AMLI and the AMLI Subsidiaries paid
for such coverage in the last full fiscal year, which amount AMLI has disclosed
to the Purchaser prior to the date hereof.

          (c) This Section 5.9 is intended for the irrevocable benefit of, and
to grant third party rights to, the Indemnified Parties and shall be binding on
all successors and assigns of Purchaser, AMLI and the Surviving Entity. Each of
the Indemnified Parties shall be entitled to enforce the covenants contained in
this Section 5.9.

          (d) In the event that the Surviving Entity (i) consolidates with or
merges into any other person or entity and shall not be the continuing or
surviving entity of such consolidation or merger or (ii) transfers or conveys
all or substantially all of its properties and assets to any person or entity,
then, and in each such case, proper provision shall be made so that such
continuing or surviving entity or transferee, as the case may be, assumes the
obligations set forth in this Section 5.9.

     Section 5.10 Tax Returns. After the Merger Effective Time, Purchaser shall
prepare and file, or cause to be prepared and filed, all Tax Returns required to
be filed by the AMLI Subsidiaries for all periods (except for their taxable
years which terminate as a result of the Merger or Partnership Merger) with the
applicable taxing authority on or before the due date (including extensions, if
any) for filing such Tax Returns.

     Section 6.2 Conditions to Obligations of Purchaser Parties. The obligations
of the Purchaser Parties to effect the Merger and to consummate the other
transactions contemplated by the Transaction Documents on the Closing Date are
further subject to the following conditions, any one or more of which may be
waived by any of the Purchaser Parties:

          (a) Representations and Warranties. The representations and warranties
of AMLI and AMLI LP contained in this Agreement (i) which are qualified by
materiality or AMLI Material Adverse Effect shall be true and correct (without
giving effect to any such materiality or AMLI Material Adverse Effect
qualifier), except where the failure of any such representation or warranty to
be so true and correct would not, individually or in the aggregate, constitute
an AMLI Material Adverse Effect and (ii) which are not qualified by materiality
or AMLI Material Adverse Effect shall be true and correct in all material
respects, in the case of each of clause (i) and (ii) as of the date hereof and
as of the Closing Date as if made on and as of such date (except to the extent
that any such representation or warranty, by its terms, is expressly limited to
a specific date, in which case, as of such specific date), and Purchaser shall
have received a certificate signed on behalf of AMLI by the Chief Executive
Officer and the Chief Financial Officer of AMLI to such effect.

shall have performed in all material respects all covenants and obligations
required to be performed by them under this Agreement at or prior to the Merger
Effective Time, and Purchaser shall have received a certificate signed on behalf
of AMLI by the Chief Executive Officer and the Chief Financial Officer of AMLI
to such effect.

          (c) Material Adverse Change. Since the date of this Agreement, there
shall have occurred no changes, events or circumstances which would,
individually or in the aggregate, constitute an AMLI Material Adverse Effect,
and Purchaser shall have received a


                                      -55-

<PAGE>

certificate signed on behalf of AMLI by the Chief Executive Officer and the
Chief Financial Officer of AMLI to such effect.

          (d) Market Conditions. There shall not have occurred (i) any general
suspension of trading in, or limitation on prices for, securities on the New
York Stock Exchange for a period in excess of five hours, (ii) a declaration of
a banking moratorium or any suspension of payments in respect of banks in the
United States (whether or not mandatory), (iii) a commencement or escalation of
a war, armed hostilities or other international or national calamity resulting
in a major dislocation of financial markets that materially and adversely
affects the ability of financial institutions in the United States to extend
credit or syndicate loans, or (iv) in the case of any of the foregoing existing
as of the date hereof, a material acceleration or worsening thereof; provided,
that upon the expiration of 30 days following the assertion of this condition by
any party, this condition shall be deemed satisfied with respect to the subject
matter of such assertion.

          (e) Tax Opinion. Purchaser and Purchaser Acquisition Entity shall have
received a tax opinion of Mayer, Brown, Rowe & Maw LLP, tax counsel to AMLI (or
other nationally recognized tax counsel to AMLI satisfactory to Purchaser),
substantially in the form attached hereto as Exhibit A and dated as of the
Closing Date, opining that each of AMLI and the AMLI Subsidiaries that file Tax
Returns as a REIT (i) has been organized and has operated in conformity with the
requirements for qualification as a REIT under the Code for all taxable periods
commencing with the date of its formation through its taxable year ending on or
before the Closing Date, and (ii) solely with respect to such AMLI Subsidiaries,
is organized in conformity with the requirements for qualification as a REIT
under the Code, and its current method of operation and ownership will enable it
to meet the requirements for qualification as a REIT for the taxable year ending
on the Closing Date, deeming for this purpose the Closing Date as the end of the
taxable year for such AMLI Subsidiaries. Such opinion shall be based, in part,
on customary assumptions and customary factual representations of AMLI and the
AMLI Subsidiaries.

     Section 6.3 Conditions to Obligations of AMLI. The obligations of AMLI and
AMLI LP to effect the Mergers and to consummate the other transactions
contemplated by the Transaction Documents on the Closing Date are further
subject to the following conditions, any one or more of which may be waived by
AMLI and AMLI LP:

          (a) Representations and Warranties. The representations and warranties
of Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition LP
contained in this Agreement (i) which are qualified by materiality, shall be
true and correct; and (ii) which are not qualified by materiality shall be true
and correct in all material respects, in each of the foregoing cases, as of the
date hereof and Closing Date as if made on and as of such date (except to the
extent that any such representation or warranty, by its terms, is expressly
limited to a specific date, in which case, as of such specific date), and AMLI
shall have received a certificate signed on behalf of the Purchaser Parties by
the President and the Chief Financial Officer of the Purchaser to such effect.

          (b) Performance of Covenants or Obligations of Purchaser Parties.
Purchaser, Purchaser Acquisition Entity and Purchaser Acquisition LP shall have
performed in all material


                                      -56-

respects all covenants and obligations required to be performed by them under
this Agreement at or prior to the Merger Effective Time, and AMLI and AMLI LP

injunction, order, decree or action by any Governmental Entity of competent
authority preventing the consummation of the Merger shall have become final and
nonappealable;

          (e) by either AMLI and AMLI LP or Purchaser, if the Merger shall not

party that has materially breached a representation, warranty or covenant of
such party set forth in this Agreement shall not be entitled to exercise its
right to terminate under this Section 7.1(e);

          (f) by either AMLI or Purchaser if, upon a vote at the AMLI

          (b) AMLI and AMLI LP agree that if this Agreement shall be terminated

Purchaser, or as directed by Purchaser, an amount equal to the Purchaser

termination, a Person (or any representative of such Person) has made any
proposal relating to a Competing Transaction and (B) within nine months of any

less any Purchaser Break-Up Expenses previously paid. Payment of any of such

directed by AMLI and AMLI LP, an amount equal to the AMLI Break-Up Expenses (as

later than five (5) Business Days after such termination. For purposes of this
Agreement, the "AMLI Break-Up Expenses" shall be an

incurred from and after September 21, 2005 in connection with this Agreement and
the other transactions contemplated hereby (including, without limitation,
reasonable attorneys', accountants' and investment bankers' fees and expenses).

          (d) The foregoing provisions of this Section 7.2 have been agreed to
by each of the parties hereto in order to induce the other parties to enter into
this Agreement and to consummate the Merger and the other transactions
contemplated by this Agreement, it being agreed and acknowledged by each of them
that the execution of this Agreement by them constitutes full and reasonable
consideration for such provisions.

          (e) In the event that either of AMLI or AMLI LP, on the one hand, or
Purchaser, on the other hand, is required to file suit to seek all or a portion
of the amounts payable under this Section 7.2, and such party prevails in such
litigation, such party shall be entitled to all expenses, including attorneys'
fees and expenses, which it has incurred in enforcing its rights under this
Section 7.2.

     Section 7.3 Effect of Termination. In the event of termination of this
Agreement by either AMLI or Purchaser as provided in Section 7.1, this Agreement

the other hand, other than as provided in the last sentence of Section 5.2,
Section 7.1, Section 7.2, this Section 7.3 and Article VIII and except to the

writing by action of their respective board of trustees or board of directors,
or other comparable bodies, at any time before or after the AMLI Shareholder

the AMLI Shareholder Approval is obtained, no such amendment, modification or
supplement shall be made that would require the approval of the AMLI Common

to pay to Purchaser the Break-Up Fee or the Purchaser Break-Up Expenses pursuant
to Section 7.2(b) or Purchaser is obligated to pay to AMLI and AMLI LP the AMLI
Break-Up Expenses pursuant to Section 7.2(c) (collectively, the "Break-Up
Amount"), AMLI (and AMLI LP if applicable) or Purchaser, as applicable (the
"Payor"), shall pay to the other party (the "Payee") from the applicable
Break-Up Amount deposited into escrow, if any, in accordance with the next
sentence, an amount equal to the lesser of (i) the Break-Up Amount and (ii) the
sum of (1) the maximum amount that can be paid to the Payee without causing the
Payee to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code
determined as if the payment of such amount did not constitute income described
in Sections 856(c)(2)(H) or 856(c)(3)(I) of the Code ("Qualifying Income"), as
determined by the Payee's independent certified public accountants, plus (2) in
the event the Payee receives either (A) a letter from the Payee's counsel
indicating that the Payee has received a ruling from the IRS described in
Section 7.6(b)(ii) or (B) an opinion from the Payee's outside counsel as
described in Section 7.6(b)(ii), an amount equal to the Break-Up Amount less the
amount payable under clause (1) above. To secure the Payor's obligation to pay
these amounts, the Payor shall deposit into escrow an amount in cash equal to
the Break-Up Amount with an escrow agent selected by the Payor and on such
customary terms (subject to Section 7.6(b)) as shall be reasonably acceptable to
each of AMLI, Purchaser and the escrow agent, provided that in the case where
the Payor is AMLI and the Payee is Purchaser, the payment or deposit into escrow
shall be at Purchaser's option. The payment or deposit into escrow of the
Break-Up Amount pursuant to this Section 7.6(a) shall be made at the time the
Payor is obligated to pay the Payee such amount pursuant to Section 7.2(b) or
Section 7.2(c), as applicable, by wire transfer of immediately available funds.

          (b) The escrow agreement shall provide that the Break-Up Amount in
escrow or any portion thereof shall not be released to the Payee unless the
escrow agent receives any one or combination of the following: (i) a letter from
the Payee's independent certified public accountants indicating the maximum
amount that can be paid by the escrow agent to the Payee without causing the
Payee to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code
determined as if the payment of such amount did not constitute Qualifying Income
or a subsequent letter from the Payee's accountants revising that amount, in
which case the escrow agent shall release such amount to the Payee, or (ii) a
letter from the Payee's counsel indicating that the Payee received a ruling from
the IRS holding that the receipt by the Payee of the Break-Up Amount would
either constitute Qualifying Income or would be excluded from gross income
within the meaning of Sections 856(c)(2) and (3) of the Code (or alternatively,
the Payee's outside counsel has rendered a legal opinion to the effect that the
receipt by the Payee of the Break-Up Amount would either constitute Qualifying
Income or would be excluded from gross income within the meaning of Sections
856(c)(2) and (3) of the Code), in which case the escrow agent shall release the
remainder of the Break-Up Amount to the Payee. The Payor agrees to amend this
Section 7.6 at the reasonable request of the Payee in order to (x) maximize the
portion of the Break-Up Amount that may be distributed to the Payee hereunder
without causing the Payee to fail to meet the requirements of Sections 856(c)(2)
and (3) of the Code, (y) improve the Payee's chances of securing a favorable
ruling described in this Section 7.6(b) or (z) assist the Payee in obtaining a
favorable legal opinion from its outside counsel as described in this Section
7.6(b). The escrow agreement shall also provide that any portion of the Break-Up
Amount held in escrow for five years shall be released by the escrow agent to
the Payor. The

Payor shall not be a party to such escrow agreement and shall not bear any cost
of or have liability resulting from the escrow agreement.
