                           PURCHASE AND SALE AGREEMENT

        THIS PURCHASE AND SALE AGREEMENT (this "Agreement") is entered into as
of the 18th day of October, 2004, by and between MG-Alamo, LLC, a Colorado
limited liability company ("Seller") and Harvard Property Trust, LLC, a Delaware
limited liability company, d/b/a Behringer Harvard Funds ("Purchaser").

                          ARTICLE 1 - PURCHASE AND SALE

        1.1     PURCHASE AND SALE. Subject to the terms and provisions in this
Agreement, Seller agrees to sell to Purchaser and Purchaser agrees to purchase
from Seller that certain parcel of land located in the City and County of
Denver, State of Colorado, as described on EXHIBIT 1.1 (the "Land), and each of
the following as is applicable to the respective portion of the Land: (i) all of
Seller's interest in the improvements, fixtures, and other items of real
property permanently affixed and located on said Land, including the office
building and parking garage constructed on the Land (which office building is
known as Alamo Plaza, having an address of 1401 17th Street, Denver, Colorado
80202); (ii) and the Personal Property (as defined in Section 1.3) (the Land
together with those of items (i) and (ii) set forth in this Section shall be
collectively referred to as the "Property."

        1.2     PURCHASE PRICE: PAYMENT OF THE PURCHASE PRICE. The purchase
price of the Property is Forty-One Million, Seven Hundred Fifty Thousand and
No/100 Dollars ($41,750,000.00) (the "Purchase Price"). The Purchase Price
(subject to the prorations to be made pursuant to this Agreement) is payable by
Purchaser as follows:

                (a)     DEPOSIT. Within two business days following delivery by
Title Company (as hereinafter defined) to Purchaser and to Purchaser's Counsel
(identified in Section 10.5 hereof) of a fully executed copy of this Agreement,
Purchaser shall deposit with LandAmerica Commercial Services having its office
at 1099 18th Street, Suite 2850, Denver, Colorado 80202, Attn: Margaret (Peppy)
Newton (tel: 303/291-3304; fax: 303/291-3301) (the "Title Company"), as agent
for Commonwealth Land Title Insurance Company ("Title Insurer"), the sum of Five
Hundred Thousand and No/100 Dollars ($500,000.00) (the "Initial Deposit") in
good funds, either by certified bank or cashier's check or by federal wire
transfer. No later than two business days following the expiration of the
Inspection Period (defined below) and as long as Purchaser has not provided
Seller with notice of termination in accordance with Section 3.4 below,
Purchaser shall deposit with Title Company an additional sum of Two Million,
Five Hundred Thousand and No/100 Dollars ($2,500,000.00) (the "Second Deposit").
The Initial Deposit, the Second Deposit, and, if applicable, the Extension
Deposit (as hereinafter defined), shall be referred to herein as the "Deposit".
The Deposit shall be in good funds, either by certified bank or cashier's check
or by federal wire transfer. The Title Company shall hold the Deposit in an
interest-bearing account reasonably acceptable to Seller and Purchaser, in
accordance with the terms and conditions of this Agreement. All interest on such
sum shall be deemed income of Purchaser, and Purchaser shall be responsible for
the payment of all costs and fees imposed on the Deposit account. The Deposit
and all accrued interest shall be distributed in accordance with the terms of
this Agreement. The failure of Purchaser to timely deliver any Deposit hereunder
shall be a material default, and shall entitle Seller, at Seller's sole option,
to terminate this

<PAGE>

Agreement immediately. If this Agreement is terminated and such termination is
not of a nature which would or may entitle Seller to retain the Deposit, the
Deposit shall be returned to Purchaser following such termination.

                (b)     PAYMENT OF PURCHASE PRICE. The Purchase Price (less the
Deposit held by the Title Company and paid to Seller on the Closing Date) shall
be paid to Seller, as adjusted by the prorations, on the Closing Date in cash by
wire transfer of immediately available federal funds.

                (c)     TITLE COMPANY. The Title Company shall act as escrow
agent and shall hold and dispose of the Deposit in accordance with the terms of
this Agreement. Seller and Purchaser agree that the duties of Title Company with
respect to the Deposit hereunder are purely ministerial in nature and shall be
expressly limited to the safekeeping and disposition of the Deposit in
accordance with this Agreement. Title Company shall incur no liability in
connection with the safekeeping or disposition of the Deposit for any reason
other than Title Company's willful misconduct or gross negligence. In the event
that Title Company shall be in doubt as to its duties or obligations with regard
to the Deposit, or in the event that Title Company receives conflicting
instructions from Purchaser and Seller with respect to the Deposit, Title
Company shall not be required to disburse the Deposit and may, at its option,
continue to hold the Deposit until both Purchaser and Seller agree as to its
disposition, or until a final judgment is entered by a court of competent
jurisdiction directing its disposition, or Title Company may interplead the
Deposit in accordance with the laws of the State of Colorado. Title Company
shall not be responsible for any interest on the Deposit except as is actually
earned, or for the loss of any interest resulting from the withdrawal of the
Deposit prior to the date interest is posted thereon. Title Company shall
execute this Agreement solely for the purpose of being bound by the provisions
of this Section 1.2.

subject to the provisions of this Agreement, are the following (collectively,

correspondence and leasing files maintained at the Land and copies of other
books, records and operating statements maintained elsewhere and Seller shall
have a right to continue to possess such other books, records and operating
statements, (ii) furniture, artwork, furnishings, fixtures, equipment,

        2.5     CONDITIONS TO PURCHASER'S OBLIGATIONS. The obligation of
Purchaser to purchase the Property pursuant to this Agreement is subject to
Seller's performance of its obligations pursuant to Section 2.2 and 2.4 hereof
in all material respects, and to the following conditions, except to the extent
such obligations or conditions are waived in writing or deemed waived under the
express terms of this Agreement:

                (a)     SELLER'S WARRANTIES AND REPRESENTATIONS. All
representations and warranties of Seller set forth in Section 2.5(e), as
supplemented or amended pursuant to that Section shall be true in all material
respects as of the Closing Date, subject to the provisions of Section 2.5(e).

                (b)     TENANT ESTOPPEL LETTERS AND SNDAS.

                        (i)     TENANT ESTOPPEL LETTERS. No later than the fifth
        (5th) day prior to the Closing Date, Seller shall have obtained estoppel
        letters substantially in the form attached hereto as EXHIBIT 2.5(B) (or
        the form or content required by any particular Lease, if different)
        ("Tenant Estoppel Certificates"), from the tenants which, in the
        aggregate, lease 80% of the rentable space then-currently leased and
        occupied in the Property in total, which Tenant Estoppel Certificates
        shall have been executed and delivered by the tenant in question without
        material modification therefrom. The required number of Tenant Estoppel
        Certificates, executed and delivered by the respective tenants in the
        manner required above, are referred to herein as the "Required
        Estoppels." Notwithstanding anything to the contrary herein, in no event
        shall a Tenant Estoppel Certificate be deemed to be unacceptable by
        Purchaser as a result of a tenant's alternation, modification, or
        deletion of the second sentence of Paragraph 5 to Exhibit 2.5(b). Seller
        shall prepare a Tenant Estoppel Certificate for each tenant and forward
        such draft estoppels to Purchaser for approval not later than the end of
        the Inspection Period; Purchaser shall give Seller comments (by
        facsimile or email) on the draft estoppels within two business days of
        receipt or otherwise be deemed to have approved such drafts, which
        process shall be repeated with respect to any comments received by
        Seller in accordance with the foregoing. Following approval by Purchaser
        (such approved tenant estoppels being the "Tenant Estoppel
        Certificates"), Seller shall promptly (following the expiration of the
        Inspection Period) deliver the certificates to the tenants and use
        reasonable efforts to obtain an executed Tenant Estoppel Certificate
        from each tenant prior to Closing. Seller shall deliver each Tenant
        Estoppel Certificate (whether or not in compliance herewith) to
        Purchaser promptly following Seller's receipt thereof. If as of the
        fifth (5th) day prior to the Closing Date Seller has not obtained and
        furnished to Purchaser the Required Estoppels, (i) Seller or Purchaser
        (if Seller fails to elect) may elect to adjourn the Closing Date up to
        10 days in order to allow more time to obtain the Required Estoppels, by
        giving notice to the other party at or prior to the Closing Date; or
        (ii) Seller may, either on the Closing Date or prior to the end of any
        such adjournment, elect to satisfy this condition by executing and
        delivering to Purchaser at the Closing its own certificate ("Landlord
        Estoppel Certificates") with respect to the remainder of the Required
        Estoppels. The Landlord Estoppel Certificate must contain a
        certification from Seller (i) identifying the Lease in

        question and all amendments and modifications thereto; (ii) stating that
        the landlord has fully performed all material obligations required to be
        performed by landlord under the Lease in question as of such date and is
        not in material default thereunder, (iii) stating that there is no
        unperformed tenant improvement work or unpaid tenant inducements that
        must be paid or performed prior to Closing. Seller shall be deemed to
        have represented and warranted each item of information contained in its
        Landlord Estoppel Certificates delivered to Purchaser, which
        representations and warranties shall survive for a period terminating on
        the earlier of (i) six months from the Closing Date, or (ii) the date on
        which Purchaser has received an executed estoppel letter satisfying the
        criteria for a Required Estoppel signed by the tenant under the
        respective Lease. Seller and Purchaser agree to cooperate with each
        other and to use good faith efforts for up to six months after the
        Closing to obtain any Required Estoppels for which Seller executed its
        own certificate at the Closing, with respect to Leases with terms
        extending past six months after the Closing.

                        (ii)    SNDAS. If, prior to Seller transmitting Tenant
        Estoppel Certificates to tenants, Purchaser provides to Seller
        subordination, non-disturbance and attornment agreements ("SNDA's")
        addressed to Purchaser's lender in the form required by the applicable
        lease (or, if no form is required, in a commercially reasonable form
        satisfactory to Purchaser's lender), completed in accordance with the
        applicable lease, Seller shall transmit the SNDAs to tenants and request
        that they be completed and returned along with the Tenant Estoppel
        Certificates, but receipt of the SNDAs shall not be a condition of
        Closing.

                (c)     TITLE EVIDENCE; SURVEY; UCC SEARCHES.

                        (i)     TITLE EVIDENCE. Promptly following delivery by
        Title Company to Purchaser and to Purchaser's Counsel of a fully
        executed copy of this Agreement, the Purchaser shall obtain for itself
        and deliver a copy to Seller of a preliminary title insurance commitment
        (the "Commitment") issued by the Title Company showing the status of
        record title to the Property, together with copies of all recorded
        documents listed as exceptions to title on Schedule B-2 of the
        Commitment (collectively, the "Exception Documents"). During the
        Inspection Period, Purchaser shall have the Title Company issue a
        revised Commitment evidencing the obligation of the Title Insurer to
        issue the current ALTA form Owner's Title Insurance Policy for the
        Property ("Title Policy") in the amount of the Purchase Price, subject
        to the following: the exception for taxes shall be revised to taxes for
        the year of closing and thereafter only, not yet due and payable, the
        exceptions listed on Schedule B-2 of the Commitment, and the exception
        for right of parties in possession shall be limited to rights of tenants
        under the Leases). If Purchaser desires to obtain an ALTA Extended
        Coverage Owner's Title Insurance Policy or additional endorsements and
        notifies the Title Company of such requested coverage and additional
        endorsements at least five business days prior to expiration of the
        Inspection Period, the Title Company shall confirm, at least three
        business days prior to the end of the Inspection Period, the status of
        meeting any requirements for obtaining the extended coverage and
        additional endorsements, which requirements shall be subject to the
        reasonable approval of Seller; if Seller reasonably objects to any
        unsatisfied requirements for obtaining such coverage or endorsements, by
        notice to Purchaser not less than two

                                       7
<PAGE>

        business days prior to the end of the Inspection Period, inclusion of
        the respective endorsements shall not be a condition of Closing, in
        which event, Purchaser may (i) waive its request for the extended
        coverage or specific endorsements, or (ii) terminate this Agreement on
        or before expiration of the Inspection Period. Seller shall pay the
        basic premium cost for the ALTA Title Insurance Policy (Standard or
        Extended Coverage, as applicable) and Purchase shall pay the cost for
        any additional endorsements requested by Purchaser to such ALTA Title
        Insurance Policy. The Commitments and the Exception Documents are
        referred to as the "Title Materials."

                        (ii)    TITLE OBJECTIONS; PERMITTED ENCUMBRANCES. If,
        from its review of the Title Materials, the Existing Survey or the UCC
        Searches (as hereinafter defined), Purchaser believes that any
        encroachment on the Property or any exception to title shown in the
        Title Materials, the Existing Survey, or UCC Searches with respect to
        the Property, would, in Purchaser's sole and absolute judgment,
        materially adversely affect the Property ("Title Objections"), Purchaser
        shall deliver to Seller notice (the "Objection Notice") of the Title
        Objections no later than 20 days after the date of this Agreement.
        During the 20 day period following Seller's receipt of the Objection
        Notice, Seller may elect (but shall have no obligation), at Seller's
        sole cost, to remove or cure or, with Purchaser's consent (which consent
        shall not be unreasonably withheld), obtain title insurance over any
        Title Objections on or before the Closing Date (the "Cure Period"). If,
        within said 20 day period, Seller does not make an election to cure or
        is unable or unwilling to remove or cure or, with Purchaser's consent,
        to obtain title insurance over all such Title Objections prior to the
        end of the Cure Period, Purchaser may, in Purchaser's sole discretion by
        notice (the "Election Notice") given to Seller within ten days after the
        end of the Cure Period, elect:

                                (1)     If requested by Seller, to grant Seller
                an additional period of up to 30 days to cure or remove or, if
                applicable, to obtain title insurance over, all uncured or
                unremoved Title Objections and, if Closing is scheduled to occur
                during such time period, the date of Closing shall be extended
                accordingly; or

                                (2)     To waive all uncured or unremoved Title
                Objections; or

                                (3)     To terminate this Agreement, after which
                the Deposit shall be returned to Purchaser and Seller and
                Purchaser shall have no further obligation or liability
                hereunder, except as otherwise expressly provided in this
                Agreement.

        If Seller does not receive an Objection Notice within such 20 day
        period, or after receiving an Objection Notice does not receive an
        Election Notice within such ten day period, Purchaser shall be deemed to
        have accepted the status of title to the Property as disclosed by the
        Title Materials, and to have waived any uncured and unremoved Title
        Objections.

                        (iii)   PERMITTED EXCEPTIONS. Any matter that is
        disclosed in the Title Materials, the Survey or the UCC Searches (other
        than Liens, as defined in subsection (v)) and to which Purchaser does
        not object (or is deemed to approve) pursuant to subsection (ii), (iv)
        or (vii) (or to which Purchaser so objects but subsequently waives or

                                       8
<PAGE>

        consents to title insurance over), and any building, zoning, subdivision
        and similar laws shall be "Permitted Exceptions."

                        (iv)    ADDITIONAL DEFECT OF TITLE. If, at any time
        prior to the Closing, Purchaser becomes aware, as a result of an updated
        Commitment or the Survey (based on updating the Existing Survey), of any
        encumbrance on or defect in title to the Property that is not a
        Permitted Exception and that was not disclosed in the Title Materials or
        Survey, and which would otherwise qualify for an Objection Notice (an
        "Additional Title Objection"), Purchaser shall give Seller notice of the
        Additional Title Objection no later than five days after receipt of the
        updated Commitment, which shall be subject to the same rights,
        requirements, elections and waivers as an Objection Notice and Election
        Notice given under subsection (ii); provided, however, that in addition
        to Seller's obligations under Section 2.5(c)(v) Seller shall be
        obligated to cure any encumbrance on or defect in title to the Property
        arising of record on or after the date of the Commitment if said matter
        is caused by the willful acts or omissions of Seller in breach of this
        Agreement. The Cure Period under subsection (ii) above for any such
        Additional Title Objection shall be for a period of 30 days from and
        after the date of the Objection Notice, and the Closing Date for the
        Property shall be extended to the last day of the Cure Period if Seller
        has elected and is making a good faith effort to cure such defect.

                        (v)     SELLER'S OBLIGATION TO REMOVE CERTAIN LIENS.
        Notwithstanding anything to the contrary in this Section 2.5(c), Seller
        shall be obligated to remove from title to the Property at Closing, and
        without any extension of the Closing Date, the following (collectively,
        the "Liens"): (i) any deeds of trust, mortgages or security interests
        created by Seller (other than those being assumed or taken subject to in
        accordance with Contracts being assumed by Purchaser), (ii) any
        mechanic's and materialmen's liens arising from the acts of Seller, and
        (iii) any other exception to title not appearing in the Commitments
        which qualifies as a Title Objection and was created or caused by the
        willful acts or omissions of Seller, in connection with the ownership or
        operation of the Property, after the date of this Agreement and that
        encumber the Property as of Closing in violation of this Agreement.
        Purchaser agrees that Seller may use the proceeds of the Purchase Price
        for the Property for the purpose of removing Liens from the Property at
        Closing.

        Notwithstanding the above, with respect to mechanics' or materialmen's
        liens, Purchaser will accept affirmative title protection rather than a
        payoff by Seller if Seller wishes to contest any such lien; or Purchaser
        will accept the removal of said lien by the furnishing of a bond or
        bonds by Seller, if the effect of said bond is to irrevocably transfer
        said lien to the bond so that said lien no longer constitutes an
        encumbrance on title.

                        (vi)    SURVEY. Seller has delivered to Purchaser a copy
        of the survey for the Property prepared by Drexel Barrell & Co. (the
        "Existing Survey"). Purchaser shall have the right and obligation to
        have the Existing Survey updated based on the Title Commitment and
        certified to Purchaser and the Title Company. Seller shall pay the
        reasonable cost and expense for updating the Existing Survey.

                                       9
<PAGE>

                        (vii)   UCC SEARCHES. During the Inspection Period,
        Purchaser shall have the right to order searches, certified to Purchaser
        by the parties performing such searches (the "UCC Searches"), conducted
        by the Title Insurer, CT Corporation System or such other nationally
        recognized search service as Purchaser may select, of the records of (i)
        the Clerk and Recorder for the City and County of Denver, State of
        Colorado, (ii) the Secretary of State of Colorado, for uniform
        commercial code financing statements, filed against the Seller or the
        Property. Purchaser shall furnish Seller with copies of all such search
        reports received by Purchaser. Any matter identified on said search
        reports to which Purchaser does not object in writing to Seller during
        the Inspection Period shall be deemed to have been accepted by
        Purchaser. Purchaser shall not object to financing statements that only
        encumber the rights of tenants under the Leases or with respect to
        personal property of tenants. Purchaser, at its expense, shall have the
        right to perform the follow up UCC Searches prior to Closing, and any
        security interests or other matters identified on such follow up UCC
        Searches arising after the date of the original UCC Searches, shall, as
        objected to by Purchaser, be removed by Seller, to the extent required
        by Section 2.5(c)(v), prior to and as a condition of closing and shall
        not constitute Permitted Exceptions, unless said security interests or
        other matters are created pursuant to Contracts that Purchaser has
        agreed to assume at Closing.

                (d)     INSPECTION OF THE PROPERTY.

                        (i)     INSPECTION PERIOD. During the period beginning
        upon the Effective Date and ending at 5:00 p.m. (local time at the
        Property) on November 2, 2004 (hereinafter referred to as the
        "Inspection Period"), Purchaser shall have the right to make a physical
        inspection of the Property, including, but not limited to, an inspection
        of the environmental condition thereof pursuant to the terms and
        conditions of this Agreement. In addition to copies of documents
        previously delivered by Seller, as soon as practicable following the
        Effective Date, Seller shall deliver to Purchaser or make available for
        its review documents and files at its office concerning the maintenance,
        operation and ownership of the Property, including, but not limited to,
        reports relating to the physical and other conditions or defects in
        respect to the Property (collectively the documents delivered or made
        available are referred to as the "Due Diligence Documents") but
        excluding Seller's partnership or corporate records, internal memoranda,
        financial projections, budgets, appraisals, accounting and tax records,
        pertaining to Seller as a business entity, and similar proprietary,
        confidential, or privileged information (collectively, the "Confidential
        Documents"). The documents and files that Seller shall make available to
        Purchaser shall include third party reports (excluding appraisals and
        excluding architectural plans for proposed development of the Property
        other than civil engineering site plans). Purchaser acknowledges that
        all such documents and files are delivered and/or made available without
        any representation or warranty of any kind. Purchaser has advised Seller
        that Purchaser must cause to be prepared up to three (3) years of
        audited financial statements in respect of the Property in compliance
        with the policies of Purchaser and certain laws and regulations,
        including, without limitation, Securities and Exchange Commission
        Regulation S-X, Rule 3-14. Seller agrees to use reasonable efforts to
        cooperate with Purchaser's auditors in the preparation of such audited
        financial statements (it being understood and agreed that the foregoing
        covenant shall survive Closing). Without limiting the generality of the
        preceding sentence (a)

                                       10
<PAGE>

        Seller shall, during normal business hours, allow Purchaser's auditors
        reasonable access to the books and records maintained by Seller (and the
        Property's property manager) in respect of the Property (excepting the
        Confidential Documents); (b) Seller shall use reasonable efforts to
        provide to Purchaser such financial information and supporting
        documentation as are necessary for Purchaser's auditors to prepare
        audited financial statements; (c) Seller will, promptly upon request of
        Purchaser, provide to Purchaser's auditors a management representation
        letter, reasonably satisfactory to Purchaser's auditors and Seller,
        addressed to Purchaser's auditors; and (d) if Seller has audited
        financial statements with respect to the Property, Seller shall promptly
        provide Purchaser's auditors with a copy of such audited financial
        statements. Purchaser shall pay for out-of-pocket costs incurred by
        Seller in connection with responding to the requests of Purchaser's
        auditors and in reviewing and providing such management representation
        letter. If after Closing Seller obtains an audited financial statement
        in respect of the Property for a fiscal period in 2003 or 2004 that was
        not completed at the time of Closing, then Seller shall promptly provide
        Purchaser with a copy of such audited financial statement, and the
        foregoing covenant shall survive Closing.

                        (ii)    Purchaser understands and agrees that any on
        site inspections of the Property shall occur at reasonable times agreed
        upon by Seller and Purchaser after reasonable prior written notice not
        to exceed 24 hours (48 hours if a weekend or holiday is involved) to
        Seller and shall be conducted so as not to interfere unreasonably with
        the use of the Property by Seller. Seller reserves the right to have a
        representative present during any such inspections. If Purchaser desires
        to do any invasive testing at the Property, other than soil borings by a
        soil testing engineer and environmental testing which are both hereby
        approved, Purchaser shall do so only after notifying Seller and
        obtaining Seller's prior written consent thereto, which consent may be
        subject to any terms and conditions imposed by Seller in its reasonable
        discretion. Purchaser agrees to provide the prompt restoration of the
        Property to its condition prior to any such inspections or tests, at
        Purchaser's sole cost and expense. Purchaser makes no representations or
        warranties with respect to anything contained in such reports received
        by Purchaser. All entries, studies and inspections shall be conducted
        consistent with the terms of the Leases and so as not to unreasonably
        disturb any tenants or unreasonably interfere with the operation or
        management of the Property. Purchaser agrees that, in making any
        inspections of, or conducting any testing of, on, or under the Property,
        Purchaser shall maintain and shall require its agents and consultants to
        maintain, in full force and effect, statutory worker's compensation
        insurance coverage and public liability and property damage insurance
        coverage in the minimum amount of $2,000,000.00, which covers the
        indemnity described below. Purchaser shall advise John Spiegleman,
        orally (at 303-773-0369) or in writing (at Seller's address), at least
        72 hours in advance of any such entry, study or inspection and of the
        names of the persons who will be making, and the nature of, the entry,
        study or inspection. Seller or its authorized employee or agent shall
        have the right to be present during each such entry, study and
        inspection. All entries on and inspections or studies of the Property
        shall be at the sole risk and expense of Purchaser, and Purchaser shall
        indemnify and hold Seller harmless from and against any and all liens,
        claims, demands, injuries, damages, costs, expenses (including also
        reasonable attorney's fees) or liability incurred by or asserted against
        Seller or the Property as a result of any of those entries, inspections
        or studies, which obligations shall

                                       11
<PAGE>

        survive the Closing or any termination of this Agreement. Purchaser
        shall not contact any lenders or other contracting party with Seller
        without prior written or oral consent of Seller, which consent shall not
        be unreasonably withheld, and Seller or its representative may be
        present at any meetings or telephone conferences with such parties.
        Seller shall be given reasonable advance notice of any scheduled
        meetings or telephone conferences with such parties. It is expressly
        agreed that Purchaser shall have the right to conduct interviews with
        tenants of the Property, subject to the rights of Seller or its
        representatives to receive notice of and be present at such interviews
        as set forth in the preceding two sentences.

        If for any reason Purchaser, in its sole and absolute discretion
        determines that the Property is not suitable for purchase by Purchaser,
        Purchaser shall have the right to terminate this Agreement, by giving
        notice to Seller on or before 5:00 p.m. Eastern Time on the expiration
        of the Inspection Period, in which event this Agreement shall terminate,
        the Deposit shall be returned to Purchaser, and, except as otherwise
        expressly provided in this Agreement, neither party shall have any
        further obligations or liability under this Agreement. If Purchaser
        fails to terminate this Agreement on or before the expiration of the
        Inspection Period, Purchaser shall be deemed to be satisfied with the
        condition of the Property (subject to Articles 5 and 6) and its
        suitability for purchase by Purchaser and this Agreement shall continue
        in full force and effect. Notwithstanding anything contained herein to
        the contrary, Seller shall not be considered to warrant the quality,
        suitability, accuracy, or any other conclusions or matters set forth in
        any tests, reports, studies, or other documents prepared by third
        parties which are provided to Purchaser with respect to the Property.

        Purchaser shall repair any damage caused by any of those entries,
        inspections or studies so as to restore the Property to its same
        condition before the damage. If this Agreement is terminated for any
        reason, within 15 days thereafter, Purchaser shall deliver to Seller all
        Due Diligence Documents and other documents it obtained from Seller or
        Seller's property manager with regard to the Property, and copies of all
        physical or environmental studies, tests, and reports relating to the
        Property performed by Purchaser or at Purchaser's request without
        warranty of any kind by Purchaser and Purchaser shall maintain in
        confidence the information it obtained about the Property.

                (e)     REPRESENTATIONS OF SELLER. Notwithstanding anything
herein to the contrary, Seller warrants and represents, as of the date of this
Agreement (subject to being updated as provided in Section 2.5(e)) to Purchaser
that:

                        (i)     To Seller's knowledge, except as set forth in
        the Due Diligence Documents, the Property is not in violation of any
        federal, state, or local law, ordinance, or regulation relating to the
        use, storage, disposal or generation of any Hazardous Materials on,
        under, or about the Property, including but not limited to soil and
        groundwater. To Seller's knowledge, there are no environmental, health,
        or safety hazards on, under, or about the Property, including but not
        limited to soil and groundwater conditions, or any of the other matters
        described above in Section 5.1. To Seller's knowledge, neither Seller
        nor any third party (including but not limited to Seller's predecessors
        in title to the Property) has used or installed any underground tank, or
        used,

                                       12
<PAGE>

        generated, manufactured, treated, stored, placed, deposited, or disposed
        of on, under, or about the Property or transported to or from the
        Property any Hazardous Materials. For purposes of this Agreement,
        "Hazardous Materials" includes substances defined as "hazardous
        substances, hazardous materials, or toxic substances" in the
        Comprehensive Environmental Response, Compensation and Liability Act of
        1980, as amended (42 United States Code ss.ss.9601, et seq.), the
        Hazardous Materials Transportation Act (49 United States Code
        ss.ss.1801, et seq.), the Resource Conservation and Recovery Act (42
        United States Code ss.ss.6901, et seq.), the substances defined as
        Hazardous Materials under the law of the state where the Property is
        located; and in the regulations adopted and publications promulgated
        under each of the aforesaid laws. Seller has no actual knowledge, except
        as otherwise disclosed to Purchaser in writing, of the existence on the
        Property of any Hazardous Material, other than de minimis amounts of
        household cleaners or office supplies.

                        (ii)    Except as set forth in EXHIBIT 2.5(E)(II), there
        is no litigation, arbitration or legal or administrative proceedings
        pending or, to the knowledge of Seller, threatened against or with
        respect to the Property that is not fully covered by insurance except
        for the deductible portion.

                        (iii)   There is no condemnation or similar proceeding
        currently pending or, to the knowledge of Seller, threatened against the
        Property.

                        (iv)    Attached hereto as EXHIBIT 2.5(E)(IV)(A) is a
        list of all Contracts, other than the Leases, currently in effect,
        together with any amendments or modifications, currently in effect.
        Attached hereto as EXHIBIT 2.5(E)(IV)(B) is a list of Leases, together
        with any amendments or modifications, currently in effect. Complete and
        accurate copies of all Contracts and Leases have been provided for
        Purchaser's review, and said copies constitute the entire agreements
        between Seller and the contracting parties or tenants, as the case may
        be.

                        (v)     With respect to the Leases, except as set forth
        on EXHIBIT 2.5(E)(V), there are not as of the date of this Agreement any
        delinquencies in excess of 30 days in the payment of rent or other
        regularly scheduled amounts payable by tenants nor to the knowledge of
        Seller are any tenants in bankruptcy proceedings; and Seller, as
        landlord under the Leases, has not committed any material defaults which
        are uncured, and, to the knowledge of Seller, has not given any tenant
        any written notice of alleged material defaults under the Leases which
        are uncured.

                        (vi)    Except as set forth on EXHIBIT 2.5(E)(VI), to
        the knowledge of Representative, Seller is not in material default under
        any Contract.

                        (vii)   Except as set forth on EXHIBIT 2.5(E)(VII), to
        the knowledge of Representative, Seller has not received any written
        notice from any governmental authority of any alleged violations (which
        are uncured as of the date of this Agreement) of any zoning, building,
        health, safety or other laws, ordinances, orders, codes or regulations
        with respect to the Property.

                        (viii)  Attached hereto as EXHIBIT 2.2(L) are rent rolls
        for the Property, prepared in the ordinary course of business by Seller
        as of the date set forth therein.

                        (ix)    The operating statements of income and expenses
        of the Property included in the Due Diligence Documents for the calendar
        years 2002 and 2003, and the portion of 2004 ended September, 2004 have
        been prepared by Seller in the ordinary course of business and, to
        Seller's knowledge, are true, correct and complete in all material
        respects and fairly represent the income and expenses of the Property
        for the periods covered in accordance with the standards and practices
        described therein, if any.

                        (x)     Any and all property management contracts and
        leasing agreements with respect to the Property shall be terminated by
        Seller as of the Closing, with Seller having fully paid and discharged
        any and all obligations accruing thereunder, subject to the provisions
        of Section 3.3 governing the payment of leasing commissions. Seller
        shall terminate the Master Lease for Alamo Plaza Parking Garage between
        Seller and MG Leasing, LLC (and cause MG Leasing, LLC to terminate the
        Parking Garage Operating Agreement with Republic Parking Systems, Inc.)
        effective at Closing and such lease shall not be deemed a Lease to be
        assigned at Closing under Section 1.3(a) or a Lease under Section
        2.5(b).

        To the extent the above or other provisions in this Agreement are
qualified to Seller's knowledge or in the knowledge of Seller, knowledge shall
mean to the actual personal present knowledge of John Spiegleman and Paul Hogan
(collectively, the "Representative"), without inquiry or investigation, and
without imputation of any knowledge of any other person, or any employee,
representative, agent or advisor of Seller. Seller represents that John
Spiegleman and Paul Hogan are the representatives of Seller who have the most
knowledge about the Property. Each Seller shall promptly advise Purchaser in
writing if, subsequent to the date of this Agreement and prior to the Closing,
it acquires actual knowledge that any of the representations and warranties set
forth in this Section 2.5(e) are no longer true or correct in any material
respect as a result of changes after the date of this Agreement, and if the
modifications are unacceptable Purchaser shall have the right to terminate this
Agreement (in which event the Deposit shall be returned to Purchaser); provided,
however, that Purchaser must notify Seller within seven days following receipt
of Seller's notice of such material modifications and provided that Seller does
not elect to correct the change in the representation or warranty so as to make
it acceptable to Purchaser in all material respects within 15 days after receipt
of Purchaser's notice of termination. Purchaser shall advise Seller in writing
if, subsequent to the date of this Agreement and prior to the Closing, it
acquires actual knowledge that any of the representations and warranties set
forth in this Section 2.5(e) or in the Tenant Estoppel Certificates is no longer
true or correct in any material respect, which notice shall be given to Seller
within five days after learning of such facts (but not later than the Closing
Date). If Purchaser gives notice to Seller, Seller shall have until the later of
the Closing Date or 15 days after receipt of Purchaser's notice to correct such
failure (and the Closing Date shall be extended accordingly). If Seller cannot
or does not elect to correct the change in the representation or warranty so as
to make it acceptable to Purchaser within such period in all material respects,
then Purchaser shall have the right to terminate this Agreement in accordance
with the following provision. These warranties and representations, as
supplemented or amended by any such subsequent disclosure, shall be restated at
Closing in Seller's Closing Certificate and shall survive Closing for a period
of six

                                       14
<PAGE>

months; provided that Purchaser shall be deemed to have waived any breach of a
representation or warranty of Seller of which Purchaser had actual knowledge
prior to Closing.

        If prior to the Closing Date Seller notifies Purchaser or Purchaser
otherwise becomes aware that one or more of the representations or warranties
are no longer true or correct in any material respect and are not waived by
Purchaser on or before the Closing Date, then unless otherwise agreed to by
Seller and Purchaser, Purchaser's exclusive remedy shall be to give notice to
Seller of Purchaser's desire to terminate this Agreement, whereupon the Deposit
shall be returned to Purchaser and this Agreement shall terminate and, except as
otherwise expressly provided in this Agreement, neither party shall have any
further rights or obligations under this Agreement. Purchaser shall not be
entitled to terminate this Agreement because of (i) any default by Seller under
any Lease or by Seller under any Contract which is cured or waived in writing by
the tenant or other contracting party, as applicable, by Closing; (ii) any
default by Seller under any Contract in question to be terminated at or prior to
Closing; or (iii) a non-monetary and non-material default under a Lease by a
tenant.

                ARTICLE 3 - CLOSING AND POST-CLOSING ADJUSTMENTS

        3.1     CLOSING ADJUSTMENTS. Unless otherwise specified, the following
are to be apportioned at the Closing on a per diem basis through and including
11:59 p.m. of the day preceding the Closing Date (provided, however, that if
Purchase Price is received by Seller after 2:00 p.m. Mountain Time on the
Closing Date, the apportionment shall be readjusted following Closing to 11:59
p.m. of the Closing Date, at Seller's option):

                (a)     TAXES AND ASSESSMENTS. Real estate taxes in Colorado are
paid in arrears. By way of example, real estate taxes assessed for calendar year
2004 are payable in 2005. Seller and Purchaser shall each be responsible for
real estate taxes assessed for their respective periods of ownership of the
Property irrespective of when such taxes are due and payable, and such taxes
shall be apportioned accordingly. The apportionment made with respect to the
year of Closing for which the tax rate or assessed valuation, or both, have not
yet been fixed shall be based upon the tax rate and/or assessed valuation last
fixed. Such proration shall be a final settlement between Seller and Purchaser
and shall not be subject to further adjustment following Closing based on the
actual taxes.

                (b)     UTILITIES. Unless final meter readings are obtained up
to the Closing Date (for which Seller shall be solely responsible), water and
sewer service charges, and charges for all other public utilities, including,
without limitation, telephone, electricity and gas based on the most recent
received billings therefor. The right to the return of any deposits with utility
companies shall be retained by Seller, and Seller shall not receive any credit
at Closing for those deposits. Purchaser agrees to immediately make any
replacement deposits which may be required by the utility companies in order for
Seller to obtain a refund of those deposits.

                (c)     RENTS. Base rents and any other amounts (including
without limitation charges for increases in operating expenses) paid for the
billing period in progress on the Closing Date. Within 60 days after Closing,
Purchaser and Seller will make a further adjustment for such rents or other
amounts which may have accrued prior to the date of Closing, but not billed or
paid as of that date to the extent collected. In addition, if following the end
of the particular

                                       15
<PAGE>

calendar year in which the Closing occurs it is determined that the estimated
operating expense pass-throughs actually paid by tenants under the Leases for
such year are more than the actual operating expenses allocable to such tenants
for the period for which such expenses are prorated, Purchaser will promptly
adjust the proration of such operating expenses and the Seller shall pay to
Purchaser any amount required as a result of such adjustment which amounts shall
be credited to the tenants, as applicable, pursuant to the terms of the Leases.
Similarly, if such estimated operating expense pass-throughs are less than the
actual operating expenses allocable to such tenants, Purchaser shall remit such
amounts to Seller if and when collected in accordance with Section 3.2 hereof.

                (d)     PERMIT AND LICENSE FEES. Permit fees and license fees
with respect to permits and licenses assigned to Purchaser.

                (e)     OPERATING ACCOUNTS. All funds in any operating accounts
or any other accounts pertaining to the Property on the Closing Date, whether in
the name of Seller or the property manager, shall be retained by Seller, and all
funds to which Seller is entitled (including without limitation, in coin
operated machines) located on the Property shall be determined by the property
manager on the Closing Date and shall be paid to Seller.

                (f)     SECURITY DEPOSITS. The security deposits and advance
rents shall not be apportioned, but instead shall be credited to Purchaser at
Closing, except to the extent such security deposits are forfeited or applied to
tenant's obligations under the Leases prior to the Closing. If any security
deposits are in the form of letters of credit, Seller shall arrange for them to
be transferred or reissued in favor of Purchaser or (if necessary) to be held
for benefit of Purchaser and Seller shall cooperate with Purchaser to draw upon
such letter of credit in accordance with the applicable Leases; such transfer or
reissuance may be completed after Closing if not practically capable of being
completed on or before Closing. Any letter of credit, transfer or reissue fees
charged by the issuing banks shall be paid by Purchaser, to the extent not
required to be paid by the respective tenant.

                (g)     CLOSING COSTS; ATTORNEYS' FEES. All real estate
recording and documentary fees payable in connection with the conveyance of the
Property and all premiums for the Title Policy, including endorsements, shall be
paid by Purchaser. All costs and expenses incurred for closing services, such as
closing fees and document preparation fees charged by the Title Company (but not
the premiums for the Title Policy), shall be paid in equal shares by Purchaser
and Seller. Except as otherwise expressly provided in this Agreement, each party
shall pay its own attorneys' fees and other expenses incurred in the preparation
of this Agreement and the sale of the Property.

                (h)     OTHER APPORTIONMENTS. Such other items as are
customarily apportioned by the Title Company at a closing of the sale of an
office building in the City and County, of Denver, Colorado or as provided in
Section 3.5.

        3.2     COLLECTION OF RECEIVABLES. Receivables," as used in this
Section, means all rental payments, expense reimbursements and other monetary
obligations of any kind past due and owing or to become past due and owing by
tenants to Seller with respect to any period prior to the Closing Date under the
Leases. Purchaser shall undertake reasonable efforts on behalf of Seller

                                       16
<PAGE>

to collect all Receivables for a period of six months from the Closing Date
(which shall include the submission of monthly invoices and follow-up invoices,
and may (but need not) include the commencement or continuation of litigation or
other proceedings), it being agreed that any monies received by Purchaser from
and after the Closing Date from any person liable for any portion of the
Receivables (including, without limitation, payments by tenants for operating
expenses in excess of their estimated payments) shall be applied (after payment
of all reasonable costs of collection, including reimbursement to Purchaser of
any legal fees or collection costs reasonably incurred by Purchaser) as follows,
unless the tenant properly identifies the payment as being for a specific item:
first to any current sums and arrearages owed to Purchaser (relating to billing
periods after the billing period in progress as of the Closing Date), second to
the payment of monies owed to Seller and Purchaser for the billing period in
progress on the Closing Date, and last to the balance of the Receivables. All
monies received by Purchaser or Seller which are to be applied pursuant to the
preceding sentence shall be held in trust by Purchaser or Seller for the benefit
of the party entitled thereto and remitted to such party promptly after receipt
in accordance with the preceding sentence.

        Notwithstanding the foregoing, Seller shall retain the sole right to
collect (in such manner as it shall deem appropriate) Receivables due from
tenants who have vacated the Property prior to the Closing Date and Purchaser
shall not be required to undertake any collection efforts with respect to those
Receivables. With respect to any pending litigation or other proceedings to
collect any Receivables from tenants in occupancy on the Closing Date, Purchaser
shall have the option of either (i) continuing the litigation or proceedings
(the costs of which shall be equitably apportioned between Seller and Purchaser,
based upon the amounts ultimately paid to each, and reimbursed out of the first
monies collected, if any) and Purchaser shall be substituted as the plaintiff,
if necessary, or (ii) not continuing the litigation, whereupon the Seller may
continue such litigation in its own name and at its sole cost and expense,
provided that such litigation shall not result in the eviction of the tenant or
the termination or modification (as to future obligations) of its Lease without
Purchaser's consent, and all sums collected by Seller as a result of the
litigation (after payment of all costs and expenses) shall be applied in full
satisfaction of the applicable Receivables.

        If, within six months following the Closing Date, any of the Receivables
to be collected by Purchaser have not been collected and paid to Seller, then
Seller may undertake its own efforts to collect those Receivables, including the
commencement of litigation and other proceedings (but Seller shall not seek to
evict any tenant or terminate any Lease), and all sums collected by Seller as a
result of such litigation (after payment of all costs and expenses) shall be
applied in full satisfaction of the applicable Receivables. Purchaser and Seller
shall reasonably cooperate with each other in the collection of Receivables and
shall execute any documents reasonably requested by the other to collect those
Receivables.

        3.3     LEASING COMMISSIONS. Seller shall be responsible for the payment
of all leasing commissions and referral fees relating to Leases entered into
prior to the execution hereof (and any Lease expansions for which the expansion
space was added to the leased premises prior to the date of this Agreement, and
any lease renewals with respect to leases expiring prior to Closing). Any
leasing commissions and referral fees as a result of any Leases executed on or
after the date of this Agreement (and any Lease expansion for which the
expansion space was added to the leased premises on or after the date of this
Agreement, and any lease renewals with respect

                                       17
<PAGE>

to leases expiring on or after Closing) shall be prorated based on prorating
such commissions and fees over the period that such tenant is obligated to pay
rent (after any deferred or free rent periods), with the Seller bearing amounts
for rent periods prior to Closing and Purchaser bearing amounts attributable to
the Closing and thereafter. Likewise, any legal fees incurred by Seller in
negotiating and evidencing any Leases executed on or after the date of this
Agreement (and any Lease expansion for which the expansion space was added to
the leased premises on or after the date of this Agreement, and any lease
renewals with respect to leases expiring on or after the date of this Agreement)
shall be likewise prorated based on the same method. Purchaser shall reimburse
Seller at the Closing to the extent Seller has paid any such leasing
commissions, referral fees or legal fees which are the responsibility of
Purchaser. Each party agrees to indemnify, defend and hold the other harmless
from and against any and all liability for leasing commissions, referral fees
and other costs and expenses owed by that party under this Section.

        3.4     TENANT IMPROVEMENTS AND OTHER EXPENSES. Seller shall be
responsible for the payment of all tenant improvement expenses (including all
hard and soft construction costs, whether payable to the contractor or to the
tenant), tenant allowances, moving expenses and other out-of-pocket costs
attributable to the Property which are the obligation of the landlord under the
new Leases entered into prior to the date of this Agreement (and any Lease
expansions for which the expansion space was added to the leased premises prior
to the date of this Agreement, and any lease renewals with respect to Leases
expiring prior to the date of this Agreement). Provided Purchaser has assumed
all future obligations for any of the above, the aggregate unpaid amounts for
which Seller is responsible shall be paid to Purchaser as a credit at Closing.
Tenant improvement expenses (including all hard and soft construction costs,
whether payable to the contractor or to the tenant), tenant allowances, moving
expenses and other out-of-pocket costs with respect to new Leases entered into
on or after the date of this Agreement (and any Lease expansions for which the
expansion space was added to the leased premises on or after the date of this
Agreement and any lease renewals with respect to leases expiring on or after the
date of this Agreement) shall be prorated based on prorating such commissions
and fees over the period that such tenant is obligated to pay rent under such
Leases or under such renewal or for such expansion space (after any deferred or
free rent periods), with Seller bearing amounts for rent periods prior to
Closing and Purchaser bearing amounts attributable to the Closing and
thereafter. Purchaser shall reimburse the Seller at the Closing to the extent
Seller has paid any such expenses which are the responsibility of Purchaser.
Seller shall in no event be obligated to pay for any change order or additions
to the tenant improvements or changes in the scope of the work or the
specifications agreed to by Purchaser and issued on or after the Closing Date.

        3.5     POST-CLOSING APPORTIONMENTS. Seller and Purchaser agree to use
reasonable efforts to calculate all apportionments (apportioned retroactive to
the Closing Date) required under this Article 3 (and to make the applicable
payments resulting from those calculations) with respect to those items of
income and expense that have not been finally determined on the Closing Date by
no later than 130 days after the Closing Date, other than operating expense
pass-throughs that are to be determined in accordance with Section 3.1. The
parties agree that each party shall have the right following Closing, on
reasonable notice to the other, from time to time to review the books and
records of such other party pertaining solely to the operation of the Property
to the extent necessary to confirm the amounts of adjustments payable to Seller
and/or Purchaser following the Closing, and Seller and Purchaser shall instruct
their respective property

                                       18
<PAGE>

managers and former property managers to make their books and records available
for this purpose.

        Purchaser and Seller shall cooperate as necessary following the Closing
Date in order to promptly and in good faith discharge their respective
obligations under this Article 3. Notwithstanding the foregoing, any claim for
an adjustment under Section 3.1 will be valid if made in writing with reasonable
specificity within six months of the Closing Date, except in the case of items
of adjustment which at the expiration of that period are subject to pending
litigation or administrative proceedings or pending tenant audits of operating
expense pass-throughs as expressly provided for under the respective leases for
periods prior to Closing and except for matters to be adjusted or paid pursuant
to Section 3.3 and 3.4. Claims with respect to items of adjustment which are
subject to litigation or administrative proceedings or such tenant audits will
be valid if made on or before the later to occur of (i) the date that is six
months after the Closing Date, and (ii) the date that is six months after a
final order is issued in such litigation or administrative hearing or the claims
subject to audit are resolved. Both parties shall use good faith efforts to
resolve any disputed claims promptly. All post Closing adjustments shall be made
in cash. The provisions of this Article 3, including, but not limited to,
Sections 3.3 and 3.4, shall survive the Closing indefinitely.

        3.6     POST-CLOSING MANAGEMENT OF THE PROPERTY. After acquisition of
the Property, Purchaser intends to retain Behringer Harvard TIC Management
Services LP, a Texas limited partnership ("BH Management") to manage and lease
the Property. At Closing, Purchaser shall cause BH Management to join with
Vector Property Services LLC, a Colorado limited liability company ("Vector") in
the execution of a subcontract for the management and leasing of the Property
whereby Vector will manage and lease the Property for a minimum period of one
year after Closing upon terms mutually acceptable to BH Management and Vector.
The parties shall endeavor to agree upon the form of agreement between BH
Management and Vector during the Inspection Period.

                              ARTICLE 4 - DEFAULT

        4.1     DEFAULT AND TERMINATION.

                (a)     PURCHASER'S DEFAULT. If Purchaser defaults in its
obligation to close Seller shall have the right, as its sole and exclusive
remedy, to terminate this Agreement and retain the Deposit as liquidated
damages. If Purchaser otherwise defaults prior to Closing or at or after Closing
and fails to cure such default within five business days following receipt of
written notice from Seller that such a default has occurred, Seller shall have
the right to obtain actual out-of-pocket money damages (excluding lost profits,
speculative or consequential damages); provided, however, that the foregoing
limitations shall not relieve or limit Purchaser's indemnification obligations
in accordance with Section 2.5(d)). THE PARTIES HAVE AGREED THAT SELLER'S ACTUAL
DAMAGES, IN THE EVENT OF A DEFAULT BY PURCHASER IN ITS OBLIGATION TO CLOSE WOULD
BE EXTREMELY DIFFICULT OR IMPRACTICABLE TO DETERMINE. THEREFORE THE PARTIES
ACKNOWLEDGE THAT THE DEPOSIT HAS BEEN AGREED UPON, AFTER NEGOTIATION, AS THE
PARTIES' REASONABLE ESTIMATE OF SELLER'S DAMAGES IN THE EVENT THAT PURCHASER
DEFAULTS IN ITS OBLIGATION TO CLOSE.

                                       19
<PAGE>

                (b)     SELLER'S DEFAULT. If Seller defaults in its obligation
to close or otherwise commits a material default under this Agreement and fails
to cure such default within five business days following receipt of written
notice from Purchaser that such a default has occurred, Purchaser shall have, as
its exclusive remedies, the following rights: (a) if the default occurs prior to
or at Closing then Purchaser may (i) terminate this Agreement and obtain the
return of the Deposit, or (ii) subject to the following limitations, treat this
Agreement as being in full force and effect and obtain specific performance
(which action shall be commenced within 60 days after the scheduled Closing
Date) to compel Seller to remove any Liens in accordance with Section 2.5(c)(v)
and convey to Purchaser such title to the Property in question as Seller is able
to convey, without any reduction in the Purchase Price except with respect to
the cost of removal of any such Liens under Section 2.5(c)(v) (if not otherwise
paid by Seller), and to recover Purchaser's actual out-of-pocket money damages
(excluding lost profits, speculative or consequential damages) from Seller only
resulting from such default, but such right to specific performance and damages
shall only be available if Seller willfully and wrongfully refuses to close in
accordance with this Agreement, despite there being no default by Purchaser and
Purchaser's being ready, willing and able to close in accordance with this
Agreement; or (b) if the default occurs after Closing, then Purchaser may obtain
its actual out-of-pocket money damages (excluding lost profits, speculative or
consequential damages) from Seller.

                (c)     TERMINATION OF AGREEMENT. Upon termination of this
Agreement in the manner set forth in this Section, except as otherwise expressly
provided in this Agreement, neither party shall have any further obligations or
liabilities hereunder. Upon termination of this Agreement, the Deposit shall be
returned to Purchaser unless such termination is of a nature which would or may
entitle Seller to retain the Deposit as set forth in this Agreement.

                     ARTICLE 5 - CASUALTY AND CONDEMNATION

        5.1     CASUALTY. In the event that prior to the Closing Date the
improvements on the Property are damaged by fire or other casualty, Seller shall
promptly notify Purchaser. If the casualty is material (defined below),
Purchaser shall have the option either (a) to terminate this Agreement by notice
given to Seller within 30 days after Purchaser receives the notice of the
casualty, or (b) to close the purchase of such Property by paying Seller the
entire Purchase Price for the Property and to the extent the damage has not been
repaired prior to the Closing, receiving all of the Seller's rights with respect
to recovery for such unrepaired damage caused by the fire or casualty under
Seller's existing insurance policies (subject to the provisions of Seller's
policy), together with a credit on the Purchase Price, for the amount of the
deductible applicable to such insurance. In the event Purchaser elects to
terminate this Agreement, the Deposit shall be returned to Purchaser and, except
as otherwise expressly provided in this Agreement, neither party shall have any
further liability or obligation to the other. A material casualty is one that
results in damage to the improvements on the Property in excess of
$1,000,000.00. If the casualty is not material and has not been completely
repaired prior to the Closing, and the remaining costs of repair are fully
covered by insurance (except for the deductible portion), Purchaser may elect to
either (x) extend the Closing until Seller shall have completed all repairs
necessary to return such Property to its pre casualty condition; or (y) close on
the scheduled Closing Date by paying Seller the entire Purchase Price for the
Property and to the extent the damage has not been repaired prior to the
Closing, receiving all of the Seller's rights with respect to recovery for such
unrepaired damage caused by the fire or casualty under Seller's existing
insurance policies

                                       20
<PAGE>

(subject to the provisions of Seller's policy). To the extent assignable, Seller
shall assign to Purchaser Seller's right to any proceeds available to Seller for
loss of rents as the result of that casualty after the Closing; provided,
however, that Seller makes no representation or warranty that any proceeds shall
be available to Purchaser for loss of rents with respect to periods after
Closing. If necessary, Seller agrees to assign its rights in such insurance to
Purchaser with respect to such casualty, subject to the provisions of Seller's
policy. Seller shall be responsible for the payment of any such repairs made
prior to the Closing and shall be entitled to the insurance proceeds applicable
to those repairs. If the casualty is not material and is not fully covered
(except for the deductible portion) by insurance of Seller and unless Seller is
willing to comply with either (x) or (y) above, Purchaser may terminate this
Agreement as Purchaser's sole remedy (in which event the Deposit shall be
returned to Purchaser). If Purchaser does not terminate this Agreement,
Purchaser shall be responsible for any such repair costs that are not covered by
insurance.

        5.2     CONDEMNATION. If, between the date of this Agreement and
Closing, any portion of the Property that is of such size and configuration or
character to be, in Purchaser's reasonable judgment, material to the operation
of the Property, is taken in condemnation (a "Material Taking") or proceedings
are commenced with respect to a Material Taking, Purchaser shall have the right
to terminate this Agreement, after which the Deposit shall be returned to
Purchaser and Seller and Purchaser shall have no further liability or obligation
under this Agreement, except as otherwise provided in this Agreement and
Purchaser shall have no right to any condemnation proceeds paid to Seller. If
Purchaser does not terminate this Agreement, Seller shall be entitled to retain
all condemnation proceeds and the Purchase Price for the Property shall be
reduced by the amount of said proceeds or, if such condemnation is not completed
as of the Closing, Seller shall assign such right to proceeds to Purchaser
without adjustment of the Purchase Price. If, between the date of this Agreement
and Closing, any portion of the Property is taken in condemnation that is not a
Material Taking, Purchaser may not terminate this Agreement for that reason, and
Seller and Purchaser shall perform their respective obligations under this
Agreement, except with respect to the part of such Property so taken, Seller
shall be entitled to all the condemnation proceeds and the Purchase Price for
the respective Property shall be decreased by the net amount of those
condemnation proceeds. If proceedings with respect to a taking which is not a
Material Taking are commenced and not completed prior to the Closing, the Seller
shall assign such right to proceeds to Purchaser without adjustment of the
Purchase Price.

       ARTICLE 6 - OPERATION OF THE PROPERTY; LEASING; SERVICE CONTRACTS

        6.1     OPERATION OF THE PROPERTY Seller agrees that between the date of
this Agreement and the Closing Date:

                (a)     Seller shall, subject only to conditions beyond Seller's
reasonable control, continue to operate and maintain the Property in its present
condition and in accordance with Seller's existing procedures, standards and
practices, ordinary wear and tear excepted; provided, however, Seller shall not
be required to expend more than Fifty Thousand and No/100 Dollars ($50,000.00)
in the aggregate on repairs and replacements for the Property over and above
that amount which is intended, pursuant to the current budget for the Property,
to be expended for such matters for the period from the date of this Agreement
to Closing and are includable as operating expenses. If such costs exceed Fifty
Thousand and No/100 Dollars ($50,000.00)

                                       21
<PAGE>

(exclusive of reimbursements due from tenants, insurance or other parties) and
the Seller is unwilling to pay the excess, Purchaser may either (i) as its sole
remedy elect to terminate this Agreement, in which case, the Deposit shall be
returned to Purchaser and except as otherwise expressly provided in this
Agreement, neither Seller nor Purchaser shall have any further liability to the
other, or (ii) subject to Closing, elect to pay the excess, in which case
Purchaser shall pay the full Purchase Price without any credit for such excess.
Purchaser shall make its election within five business (5) days after notice
from Seller that Seller is unwilling to pay the excess. Purchaser's failure to
respond shall be deemed an election under (i).

                (b)     Seller shall not initiate or consent to any proposed
changes in the zoning or other governmental land use requirements applicable to
all or any part of the Property.

                (c)     Seller shall maintain in full force or effect their
existing insurance coverage on the Property as disclosed to Purchaser.

                (d)     Subject to the above provisions of Section 6.1(a),
Seller shall use commercially reasonable efforts to preserve in force all
existing permits and to cause all those expiring prior to the Closing Date to be
renewed. If any such permit shall be suspended or revoked, Seller shall promptly
so notify Purchaser and shall take all reasonable measures necessary to cause
the reinstatement of such permit prior to Closing without any additional
limitation or condition.

                (e)     Seller will not dispose of any portion of the Property,
except in the ordinary course of business (which shall include the normal use of
consumable supplies) and in accordance with this Agreement. Seller shall
maintain or cause to be maintained through Closing a normal inventory of
supplies and Other Personal Property in accordance with Seller's existing
procedures, standards and practices.

        6.2     LEASING. From the date of this Agreement until the expiration of
the Inspection Period, before entering into any new Leases for space at the
Property or into an agreement with a tenant to materially modify or terminate
any Leases, Seller shall provide Purchaser with a courtesy copy of any term
sheet, and promptly after entering into any such new Leases or agreements,
Seller shall provide Purchaser with a copy of each executed new Lease and
agreements, but in no event shall Purchaser's consent be required during this
period for the execution of any new Leases or such agreements. However, from the
expiration of the Inspection Period until the Closing Date, Seller shall not,
without Purchaser's prior written approval: (i) voluntarily terminate (except in
the case of a default and provided Purchaser is notified prior to termination),
modify, renew, or accept a surrender in whole or in part (except in the case of
a renewal, modification, expansion, or expiration pursuant to the terms of the
Lease and with respect to which the landlord is not entitled to exercise
discretion) of any of the Leases, or (ii) enter into any new Leases. Purchaser
shall notify Seller in writing within five business days after its receipt of
each proposed termination, modification or renewal of an existing Lease or
proposed new Lease, along with the final form of the new Lease or Lease
amendment, if applicable, all available exhibits to those Leases, any written
information Seller has received about the tenant, and the cost of all tenant
improvement work and leasing commissions to be incurred by the landlord in
connection with the Lease, of either its approval or disapproval. If Purchaser
fails to notify Seller of its approval or disapproval of any such termination,
modification, renewal or proposed new

                                       22
<PAGE>

Lease within this five business day period, Purchaser shall be deemed to have
approved it. Seller agrees, from and after the date of this Agreement, to
provide Purchaser with copies of all material written notices or correspondence
given to or by a tenant under the Leases.

        6.3     SERVICE CONTRACTS. Seller agrees that after the date of this
Agreement it will not enter into any Contracts which cannot be terminated by
Seller at no cost to Purchaser on or before the Closing Date without the prior
written consent of Purchaser. At least two business days before the end of the
Inspection Period, Purchaser shall deliver a notice to Seller specifying which
of the Contracts it intends to assume and which Contracts Purchaser requests
that Seller terminate on or before the Closing Date. On or before the Closing
Date, Seller shall terminate all Contracts that Purchaser has so requested to be
terminated, if such Contracts can be legally terminated.

                (a)     With respect to those Contracts that cannot be
terminated, Purchaser shall be deemed to have agreed to assume those Contracts
unless Purchaser terminates this Agreement under Section 2.5(d)(i).

                (b)     With respect to those Contracts which can be terminated,
but only with the payment of a fee or penalty which Seller is unwilling to pay,
Purchaser shall be deemed to have agreed to pay such fee and assume those
Contracts if Purchaser does not terminate this Agreement under Section
2.5(d)(i).

                         ARTICLE 7 - GENERAL DISCLAIMER

        Except as otherwise expressly stated in this Agreement or in any
agreement or instrument executed and delivered by Seller to Purchaser at the
Closing, including but not limited to representations and warranties set forth
in Section 2.5(e) of this Agreement and the limited warranty of title expressly
set forth in the Deed (collectively, the "Surviving Representations"), Seller
hereby expressly disclaims making any and all representations and warranties of
any kind or character, express or implied, with respect to the Property, and
Purchaser agrees to accept the Property "as is, where is, with all faults."
Without limiting the generality of the preceding sentence or any other
disclaimer set forth herein, Seller and Purchaser hereby agree that, except for
the Surviving Representations, Seller has not made and is not making any
representations or warranties, express or implied, written or oral, as to (a)
the nature or condition, physical or otherwise, of the Property or any aspect
thereof, including, without limitation, any warranties of habitability,
suitability, merchantability or fitness for a particular use or purpose; (b) the
nature or quality of construction, structural design or engineering of the
improvements or the state of repair or lack or repair of any of the
improvements; (c) the quality of the labor or materials included in the
improvements; or (d) the compliance of the Property or the operation or use of
the Property with any laws, ordinances or regulations of any governmental body,
including, without limitation, the Americans with Disabilities Act, any
Environmental Laws, and any zoning laws or ordinances.

        Purchaser has been or will be given the opportunity to inspect the
Property and the Leases, Contracts, and Due Diligence Materials (including,
without limitation, Title Materials) relating to the Property that Purchaser
deemed necessary to inspect and review in connection with this Agreement, and
Purchaser has retained such environmental consultants, structural

                                       23
<PAGE>

engineers, and other experts as it deemed necessary to inspect the Property and
review such materials and to make its own determination as to the condition of
the Property and its suitability for Purchaser's purposes, as to whether
hazardous or toxic materials were used, released or stored on the Property or
constitute a present hazard with respect to the Property, and otherwise.
Purchaser is relying on its own investigation and the advice of its experts
regarding the Property, and upon its review of Leases, Contracts, and Due
Diligence Materials, and not on any representations or warranties of Seller
(other than the Surviving Representations), and Purchaser acknowledges that the
Purchase Price reflects the fact that this is an "as is, where is" transaction
except as may be expressly set forth in the Surviving Representations. Purchaser
specifically waives any claim it may have against Seller arising from (1) any
condition which now exists or may be found to exist in, on, under or about the
Property, (2) a determination that the Property or any portion violates any
applicable environmental or health or safety law, ordinance, regulation or
ruling, and (3) the presence, use, generation, storage, release, threatened
release, or containment, treatment, or disposal of any Hazardous Materials. The
covenants and agreements of Purchaser in this paragraph shall survive the
Closing and consummation of the transactions contemplated by this Agreement.

                           ARTICLE 8 - MISCELLANEOUS

        8.1     CONFIDENTIALITY. Subject to the provisions of Section 8.22 of

agreed that Purchaser may disclose such data and information to (a) the
employees, consultants, accountants, attorneys and prospective lenders of
Purchaser provided that such persons agree to treat such data and information
confidentially in accordance with this provision, and (b) as permitted by the
provisions of Section 8.22. In the event this Agreement is terminated or
Purchaser fails to perform hereunder, Purchaser shall, upon the written request
of Seller, promptly return to Seller any statements, documents, schedules,
exhibits or other written information obtained from Seller or any agent of
Seller in connection with this Agreement or the transaction contemplated herein.
In the event of a breach or threatened breach by Purchaser or its agent or
representatives of this Section 8.1, Seller shall be entitled to an injunction
restraining Purchaser or its agents or representatives from disclosing, in whole
or in part, such confidential information. Nothing herein shall be construed as
prohibiting Seller from pursuing any other available remedy at law or in equity
for such breach or threatened breach except that Purchaser shall not be liable
for any consequential, special or punitive damages. The provisions of this
Section 8.1 shall survive Closing. Notwithstanding anything contained
hereinabove to the contrary, (i) this provision shall not apply to any
information that is or becomes generally available to the public from a source
other than Purchaser or its representatives or is disclosed to Purchaser or its
representatives by a third party who is not known to Purchaser to be subject to
a similar provision and (ii) Purchaser may disclose any such information
pursuant to a court order, subpoena, or similar judicial requirement.

        8.4     ASSIGNABILITY.

                (a)     PURCHASER'S ASSIGNABILITY. Purchaser cannot assign all

Investors"). Notwithstanding anything contained in this Agreement to the
contrary, Seller and Purchaser agree as follows: (a) Purchaser shall have the
right to distribute information about the Property and this Agreement to brokers
who may facilitate the sale of such tenant in common interests and to potential
TIC Investors and their advisors, subject to data and information with respect
to Seller's business being disclosed on a confidential basis (such information
may be disclosed in a confidential private placement memorandum) (Seller shall
incur no liability in connection with Purchaser's distribution of information to
and facilitation with the TIC Investors as described herein); and (b) Purchaser
shall have the right to assign its rights under this Agreement in accordance
with Section 8.4 to two related parties (each referred to herein as a "Behringer
Entity"), Behringer Harvard Alamo Plaza H, LLC, and Behringer Harvard Alamo
Plaza S, LLC, with the understanding that following the Closing such Behringer
Entity may convey interests in the Property directly to such TIC Investors. The
TIC Investors shall not be deemed third party beneficiaries under this
Agreement; provided, however, each Behringer Entity may pursue any rights under
this Agreement on their own behalf or on behalf of the TIC Investors. Purchaser
and each Behringer Entity agrees to indemnify, hold harmless and defend Seller
from and against any loss, cost, claim, cause of action, damage, or expense,
including reasonable attorneys' fees, which Seller may incur, or which may be
asserted against Seller under this Agreement by any or all of the TIC Investors
except that such indemnity shall not apply if Seller is deemed by a court of
competent jurisdiction to have committed fraud in connection with the sale of
the Property or to be in

                                       28
<PAGE>

breach of this Agreement which breach relates to the claims by any or all of the
TIC Investors.

obtained), in and to all trade names, trademarks, logos and service marks (in
each case, if any) utilized solely by Seller in connection with the

                                        7

operation of the Real Property and Improvements (other than the names or
variations thereof of Seller, its Affiliates, the property manager and Tenants);

        SECTION 2.2     INDIVISIBLE ECONOMIC PACKAGE. Purchaser has no right to
purchase, and Seller has no obligation to sell, less than all of the Property,
it being the express agreement and understanding of Purchaser and Seller that,
as a material inducement to Seller and Purchaser to enter into this Agreement,
Purchaser has agreed to purchase, and Seller has agreed to sell, all of the
Property, subject to and in accordance with the terms and conditions hereof.

                                  ARTICLE III
                                  CONSIDERATION

        SECTION 3.1     PURCHASE PRICE. The purchase price for the Property (the
"PURCHASE PRICE") will be FORTY SIX MILLION THREE HUNDRED THOUSAND and No/100
Dollars ($46,300,000.00) in lawful currency of the United States of America,
payable as provided in Section 3.3. To the extent that the Prepayment Premium is
less than the prepayment premium that would have otherwise been payable had such
premium been calculated in accordance with Section 2.3(4) of the Traveler's Loan
Agreement (the "HYPOTHETICAL PREPAYMENT PREMIUM"), the Purchase Price shall be
increased by one-half (1/2) of the amount by which the Prepayment Premium is
less than the Hypothetical Prepayment Premium. For example, if the Hypothetical
Prepayment Premium is $1,500,000 and the Prepayment Premium is $1,000,000, the
Purchase Price shall be increased by $250,000 (($1,500,000 - $1,000,000) x 1/2.)

        SECTION 3.2     ASSUMPTION OF OBLIGATIONS.

                (a)     As additional consideration for the purchase and sale of
the Property, effective as of Closing, Purchaser will be deemed to have, and by
virtue of closing the purchase of the Property Purchaser shall have: (1) assumed
and agreed to perform or pay, as applicable, (i) all of the covenants and
obligations of Seller, Seller's predecessor in title and Seller's Affiliates
pursuant to the Tenant Leases and Service Contracts assigned to Purchaser and
which are to be performed subsequent to the Closing Date, (ii) all obligations
under the Tenant Leases and the Service Contracts assigned to Purchaser and
relating to the physical or environmental condition of the Property, regardless
of whether such obligations arise before or after the Closing Date and (iii) the
Leasing Costs for which Purchaser is responsible under Section 10.4(e) below;
and (2) assumed and agreed to discharge, perform and comply with each and every
liability, duty, covenant, debt or obligation of Seller or any of its Affiliates
resulting from, arising out of or in any way related to the Licenses and Permits
and arising or accruing on or after the Closing Date. Purchaser hereby
indemnifies, defends, and holds Seller and its Affiliates harmless from and
against any and all claims, liens, damages, demands, causes of action,
liabilities, lawsuits, judgments, losses, costs and expenses (including without
limitation, reasonable attorneys' fees and expenses) asserted against or
incurred by Seller or its Affiliates and arising out of the failure of Purchaser
to perform its obligations pursuant to this Section 3.2(a). The provisions of
this Section 3.2(a) shall fully survive the closing without limitation.

                (b)     Effective as of Closing, Seller will be deemed to have,
and by virtue of closing the sale of the Property Seller shall have, agreed to
indemnify and hold Purchaser harmless from and against any and all claims,
liens, damages, demands, causes of action,

                                        8

liabilities, lawsuits, judgments, losses, costs and expenses (including without
limitation, reasonable attorneys' fees and expenses) asserted against or
incurred by Purchaser by reason of or arising out of any failure by Seller to
perform its obligations under the Service Contracts and Tenant Leases assigned
to Purchaser to the extent the same arose prior to the Closing Date, other than
(1) any obligations relating to the physical or environmental conditions of the
Property, and (2) any Leasing Costs, which obligations are expressly assumed by
Purchaser as provided in Section 3.2(a) above; provided, however, that Seller's
obligations under this subsection (b) shall not apply to any claims which (i)
are based on any matter which is identified in this Agreement (including the
Schedules and Exhibits hereto) as an exception or qualification to any
representation or warranty of Seller set forth herein, or in any estoppel
certificate delivered to Purchaser at or prior to the Closing pursuant to this
Agreement by any Tenant, (ii) are based on any matter constituting a breach of
Seller's representations and warranties that is deemed waived by Purchaser
pursuant to the terms of this Agreement or (iii) are based on a liability which
was taken into account as a Closing adjustment pursuant to Section 10.4. The
provisions of this Section 3.2(b) are subject in all events to the provisions of
Section 16.1 below. This Section 3.2(b) shall survive Closing only to the extent
provided in Section 16.1 below.

        SECTION 3.3     METHOD OF PAYMENT OF PURCHASE PRICE. No later than the
Deposit Time, Purchaser will deposit in escrow with the Title Company the
Purchase Price (subject to adjustments described in Section 10.4), together with
all other costs and amounts to be paid by Purchaser at Closing pursuant to the
terms of this Agreement, by Federal Reserve wire transfer of immediately
available funds to an account to be designated by the Title Company. No later
than 2:00 p.m. Dallas, Texas time on the Closing Date: (a) Purchaser will cause
the Title Company to (i) pay to Seller by Federal Reserve wire transfer of
immediately available funds to an account to be designated by Seller, the

this Agreement, and (ii) pay to all appropriate payees the other costs and
amounts to be paid by Purchaser at Closing pursuant to the terms of this
Agreement; and (b) Seller will direct the Title Company to pay to the
appropriate payees out of the proceeds of Closing payable to Seller, all costs
and amounts to be paid by Seller at Closing pursuant to the terms of this
Agreement.

        SECTION 3.4     INDEPENDENT CONSIDERATION. The sum of One Hundred
Dollars ($100.00) (the "INDEPENDENT CONSIDERATION") out of the Earnest Money
Deposit is independent of any other consideration provided hereunder, shall be
fully earned by Seller upon the Effective Date hereof, and is not refundable to
Purchaser under any circumstances. Accordingly, if this Agreement is terminated
for any reason by either party, the Independent Consideration shall be paid by
the Title Company to Seller.

                                   ARTICLE IV
                  EARNEST MONEY DEPOSIT AND ESCROW INSTRUCTIONS

        SECTION 4.1     THE DEPOSIT. Within two (2) Business Days after the
execution and delivery of this Agreement by Purchaser and Seller, Purchaser
shall deposit with the Title Company, in good funds immediately collectible by
the Title Company, the sum of One Million and No/100 Dollars ($1,000,000.00)
(the "FIRST DEPOSIT"), which will be held in escrow by the Title Company
pursuant to the terms of this Agreement. If Purchaser has not previously

                                        9
<PAGE>

expiration of the Inspection Period, Purchaser shall deposit with the Title
Company, in good funds immediately collectible by the Title Company, an
additional sum of One Million and No/100 Dollars ($1,000,000.00) (the "SECOND
DEPOSIT"), which will be held in escrow by the Title Company pursuant to the
terms of this Agreement. The Deposit (plus all interest earned thereon), and the
Second Deposit (plus all interest earned thereon), when deposited, less the
Independent Consideration, shall be the "EARNEST MONEY DEPOSIT" for purposes of
this Agreement. If Purchaser fails to timely make the Second Deposit, then
Purchaser shall be in default hereunder, and Seller shall be entitled to
exercise its rights and remedies under Section 13.2. At Closing, the Earnest
Money Deposit shall be applied towards payment of the Purchase Price.

        SECTION 4.2     ESCROW INSTRUCTIONS. Article IV of this Agreement
constitutes the escrow instructions of Seller and Purchaser to the Title Company
with regard to the Earnest Money Deposit and the Closing (the "ESCROW
INSTRUCTIONS"). By its execution of the joinder attached hereto, the Title
Company agrees to be bound by the provisions of this Article IV. If any
requirements relating to the duties or obligations of the Title Company
hereunder are not acceptable to the Title Company, or if the Title Company
requires additional instructions, the parties agree to make such deletions,
substitutions and additions to the Escrow Instructions as Purchaser and Seller
hereafter mutually approve in writing and which do not substantially alter this
Agreement or its intent. In the event of any conflict between this Agreement and
such additional escrow instructions, this Agreement will control.

        SECTION 4.3     DOCUMENTS DEPOSITED INTO ESCROW. On or before the
Deposit Time, (a) Purchaser will cause the difference between the Purchase Price
and the Deposit and interest thereon (subject to the prorations provided for in
Section 10.4 and with the addition of all Closing costs to be paid by Purchaser)
to be transferred to the Title Company's escrow account, in accordance with the
timing and other requirements of Section 3.3, (b) Purchaser will deliver in
escrow to the Title Company the documents described and provided for in Section
10.2(b), (c), (d) and (e) below, and (c) Seller will deliver in escrow to the
Title Company the documents described and provided for in Section 10.3(a), (b),
(c), (d), (e), (f), (g), (i) and (l) below.

        SECTION 4.4     CLOSE OF ESCROW. Provided that the Title Company has not
received from Seller or Purchaser any written termination notice as described
and provided for in Section 4.5 (or if such a notice has been previously
received, provided that the Title Company has received from such party a
withdrawal of such notice), when Purchaser and Seller have delivered the
documents required by Section 4.3, the Title Company will:

                (a)     If applicable and when required, file with the Internal
Revenue Service (with copies to Purchaser and Seller) the reporting statement
required under Section 6045(e) of the Internal Revenue Code and Section 4.9;

                (b)     Insert the applicable Closing Date as the date of any
document delivered to the Title Company undated, and assemble counterparts into
single instruments;

                (c)     Disburse to Seller, by wire transfer to Seller of
immediately available federal funds, in accordance with wiring instructions to

<PAGE>

Seller, all sums to be received by Seller from Purchaser at the Closing,
comprised of the Purchase Price as adjusted in accordance with the provisions of
this Agreement;

                (d)     Deliver the Deed to Purchaser by agreeing to cause the
same to be recorded in the Official Records and agreeing to obtain conformed
copies of the recorded Deed for delivery to Purchaser and to Seller following
recording;

                (e)     Issue to Purchaser the Title Policy required by Section
6.2(a) of this Agreement;

                (f)     Deliver to Seller, in addition to Seller's Closing
proceeds, all documents deposited with the Title Company for delivery to Seller
at the Closing; and

                (g)     Deliver to Purchaser (i) all documents deposited with
the Title Company for delivery to Purchaser at the Closing and (ii) any funds
deposited by Purchaser in excess of the amount required to be paid by Purchaser
pursuant to this Agreement.

        SECTION 4.5     TERMINATION NOTICES. Other than as provided in Section
5.4, if at any time the Title Company receives a certificate of either Seller or
Purchaser (for purposes of this Section 4.5, the "CERTIFYING PARTY") stating
that: (a) the Certifying Party is entitled to receive the Earnest Money Deposit
pursuant to the terms of this Agreement, and (b) a copy of the certificate was
delivered as provided herein to the other party (for purposes of this Section
4.5, the "OTHER PARTY") prior to or contemporaneously with the giving of such
certificate to the Title Company, then, unless the Title Company has then
previously received, or receives within three (3) Business Days after receipt of
the Certifying Party's certificate, contrary instructions from the Other Party,
the Title Company, within one (1) Business Day after the expiration of the
foregoing three (3) Business Day period, will deliver the Independent
Consideration to Seller and the Earnest Money Deposit to the Certifying Party,
and thereupon the Title Company will be discharged and released from any and all
liability hereunder. If the Title Company receives contrary instructions from
the Other Party within three (3) Business Days following the Title Company's
receipt of said certificate, the Title Company will not so deliver the Earnest
Money Deposit, but will continue to hold the same pursuant hereto, subject to
Section 4.6.

        SECTION 4.6     INDEMNIFICATION OF TITLE COMPANY. If this Agreement or
any matter relating hereto becomes the subject of any litigation or controversy,
Purchaser and Seller jointly and severally, will hold Title Company free and
harmless from any loss or expense, including reasonable attorneys' fees, that
may be suffered by it by reason thereof other than as a result of Title
Company's gross negligence or willful misconduct. In the event conflicting
demands are made or notices served upon Title Company with respect to this
Agreement, or if there is uncertainty as to the meaning or applicability of the
terms of this Agreement or the Escrow Instructions, Purchaser and Seller
expressly agree that the Title Company will be entitled to file a suit in
interpleader and to obtain an order from the court requiring Purchaser and
Seller to interplead and litigate their several claims and rights among
themselves. Upon delivery of the Independent Consideration to Seller and the
filing of the action in interpleader and the deposit of the Earnest Money
Deposit into the registry of the court, the Title Company will be fully released
and discharged from any further obligations imposed upon it by this Agreement
after such deposit.

        SECTION 4.7     MAINTENANCE OF CONFIDENTIALITY BY TITLE COMPANY. Except
as may otherwise be required by law or by this Agreement, Title Company will
maintain in strict confidence and not disclose to anyone the existence of this
Agreement, the identity of the parties hereto, the amount of the Purchase Price,
the provisions of this Agreement or any other information concerning the
transactions contemplated hereby, without the prior written consent of Purchaser
and Seller in each instance.

        SECTION 4.8     INVESTMENT OF EARNEST MONEY DEPOSIT. Title Company will
invest and reinvest the Deposit, at the instruction and sole election of
Purchaser, only in (a) bonds, notes, Treasury bills or other securities
constituting direct obligations of, or guaranteed by the full faith and credit
of, the United States of America, and in no event maturing beyond the Closing
Date, or (b) an interest-bearing account at a commercial bank mutually
acceptable to Seller, Purchaser and Title Company. The investment of the Deposit
will be at the sole risk of Purchaser and no loss on any investment will relieve
Purchaser of its obligations to pay to Seller as liquidated damages the original
amount of the Deposit as provided in Article XIII, or of its obligation to pay
the Purchase Price. All interest earned on the Deposit will be the property of
Purchaser and will be reported to the Internal Revenue Service as income until
such time as Seller is entitled to the Deposit pursuant to this Agreement.
Purchaser will provide the Title Company with a taxpayer identification number
and will pay all income taxes due by reason of interest accrued on the Deposit.

        SECTION 4.9     DESIGNATION OF REPORTING PERSON. In order to assure
compliance with the requirements of Section 6045 of the Internal Revenue Code of
1986, as amended (for purposes of this Section 4.9, the "CODE"), and any related
reporting requirements of the Code, the parties hereto agree as follows:

                (a)     The Title Company (for purposes of this Section 4.9, the

                        (i)     to provide to the Reporting Person all
        information and certifications regarding such party, as reasonably
        requested by the Reporting Person or otherwise required to be provided
        by a party to the transaction described herein under Section 6045 of the
        Code; and

                        (ii)    to provide to the Reporting Person such party's
        taxpayer identification number and a statement (on Internal Revenue
        Service Form W-9 or an acceptable substitute form, or on any other form
        the applicable current or future Code sections and regulations might
        require and/or any form requested by the Reporting Person), signed under
        penalties of perjury, stating that the taxpayer identification number
        supplied by such party to the Reporting Person is correct.

                (c)     Each party hereto agrees to retain this Agreement for

                (d)     The addresses for Seller and Purchaser are as set forth

                                   ARTICLE V

        SECTION 5.1     ENTRY AND INSPECTION.

                (a)     From and after the Effective Date, but subject to the
provisions of this Section 5.1 and subject to the obligations set forth in
Section 5.3 below, Seller will permit Purchaser and its authorized agents and
representatives (collectively, the "LICENSEE PARTIES") the right to enter upon
the Real Property at all reasonable times during normal business hours to
perform inspections of the Property and communicate with Tenants and service
providers; provided, however, Purchaser shall not have the right to communicate
with Tenants or service providers unless interviews and communications are
coordinated through Seller and Seller shall have the right to participate in any
such communications. Purchaser will provide to Seller written notice of the
intention of Purchaser or the other Licensee Parties to enter the Real Property
at least 48 hours prior to such intended entry and specify the intended purpose
therefor and the inspections and examinations contemplated to be made and/or the
Tenants and service providers with whom any Licensee Party will communicate. At
Seller's option, Seller may be present for any such entry, inspection and
communication with any Tenants or service providers. Notwithstanding anything to
the contrary contained herein, no physical testing or sampling shall be
conducted during any such entry by Purchaser or any Licensee Party upon the Real
Property without Seller's specific prior written consent, which consent may be
withheld, delayed or conditioned in Seller's sole and absolute discretion;
provided, however, that prior to giving any such approval, Seller shall be
provided with a written sampling plan in reasonable detail in order to allow
Seller a reasonable opportunity to evaluate such proposal. If Purchaser or the
other Licensee Parties undertake any borings or other disturbances of the soil,
the soil shall be recompacted to its condition as existed immediately before any
such borings or other disturbances were undertaken. If Purchaser or any Licensee
Party takes any sample from the Real Property in connection with any testing,
Purchaser shall, upon the request of Seller, provide to Seller a portion of such
sample being tested to allow Seller, if it so chooses, to perform its own
testing.

                (b)     Subject to the obligations set forth in Section 5.3
below, the Licensee Parties shall have the right to communicate directly with
the Authorities for any good faith reasonable purpose in connection with the
transaction contemplated by this Agreement (so long as any such communications
made during the Inspection Period are conducted without disclosing that a sale
of the Property is contemplated).

        SECTION 5.2     DOCUMENT REVIEW.

                (a)     Seller has made available prior to the execution and
delivery of this Agreement, or will make available within two (2) Business Days
after the execution and delivery of this Agreement, to Purchaser and its
authorized agents or representatives for review, inspection, examination,
analysis, verification and photocopying, at either the office of Seller,

                                       13
<PAGE>

Seller's property manager or at the Real Property, the following relative to the
Property to the extent in Seller's possession or control (collectively, the
"DOCUMENTS"): (i) all existing environmental reports and studies of the Property

and personal property tax bills, covering the year preceding the Effective Date;
(iii) Seller's most current rent roll (the "RENT ROLL"); (iv) operating
statements for the previous time period covering the period of Seller's
ownership of the Property; (v) copies of the Tenant Leases, the Service
Contracts, the Licenses and Permits and the Records and Plans; and (vi) a
current inventory of the Personal Property.

                (b)     Purchaser acknowledges that any and all of the Documents
may be proprietary and confidential in nature and have been provided to
Purchaser solely to assist Purchaser in determining the feasibility of
purchasing the Property. Subject only to the provisions of Article XII and
Section 17.16, Purchaser agrees not to disclose the contents of the Documents,
or any of the provisions, terms or conditions contained therein, to any party
outside of Purchaser's organization other than its attorneys, partners,
accountants, consultants, lenders or investors (collectively, for purposes of
this Section 5.2(b), the "PERMITTED OUTSIDE PARTIES"). Purchaser further agrees
that within its organization, or as to the Permitted Outside Parties, the
Documents will be disclosed and exhibited only to those persons within
Purchaser's organization or to those Permitted Outside Parties who are
responsible for determining the feasibility of Purchaser's acquisition and
financing of the Property. Purchaser further acknowledges that the Documents and
other information relating to the leasing arrangements between Seller and the
Tenants or prospective tenants are proprietary and confidential in nature.
Subject to the provisions of Section 17.16, Purchaser agrees not to divulge the
contents of such Documents and other information except in strict accordance
with the confidentiality standards set forth in this Section 5.2 and Article
XII. In permitting Purchaser and the Permitted Outside Parties to review the
Documents or information to assist Purchaser, Seller has not waived any
privilege or claim of confidentiality with respect thereto, and no third party
benefits or relationships of any kind, either express or implied, have been
offered, intended or created by Seller and any such claims are expressly
rejected by Seller and waived by Purchaser and the Permitted Outside Parties,
for whom, by its execution of this Agreement, Purchaser is acting as an agent
with regard to such waiver.

                (c)     Purchaser will return to Seller all copies Purchaser has
made of the Documents and all copies of any studies, reports or test results
regarding any part of the Property obtained by Purchaser, before or after the
execution of this Agreement, in connection with Purchaser's inspection of the
Property (collectively, "PURCHASER'S INFORMATION") not later than ten (10)
Business Days following the time this Agreement is terminated for any reason.

                (d)     Purchaser acknowledges that some of the Documents may
have been prepared by third parties and may have been prepared prior to Seller's
ownership of the Property. Purchaser hereby acknowledges that, except as
expressly provided in Section 8.1 below, Seller has not made and does not make
any representation or warranty regarding the truth, accuracy or completeness of
the Documents or the sources thereof (whether prepared by Seller, Seller's
Affiliates or any other person or entity). Seller has not undertaken any
independent investigation as to the truth, accuracy or completeness of the
Documents and is providing the Documents solely as an accommodation to
Purchaser.

                                       14
<PAGE>

                (e)     Notwithstanding any provision of this Agreement to the
contrary, no termination of this Agreement will terminate Purchaser's
obligations pursuant to this Section 5.2.

                (f)     Purchaser has advised Seller that Purchaser must cause
to be prepared up to three (3) years of audited financial statements in respect
of the Property in compliance with the policies of Purchaser and certain laws
and regulations, including, without limitation, Securities and Exchange
Commission Regulation S-X, Rule 3-14. Seller agrees (i) to use commercially
reasonable efforts to cooperate to make information available to Purchaser's
auditors in connection with the preparation of such audited financial
statements, and (ii) to make Seller's property manager and Seller's asset
manager in respect of the Property available for interview in connection with
the conduct of such audit (it being understood and agreed that the foregoing
covenants shall survive Closing). Notwithstanding the foregoing covenants,
Seller shall have no obligation to take any action that may reasonably be
expected to expose Seller to liability from Purchaser's auditors.

        SECTION 5.3     ENTRY AND INSPECTION OBLIGATIONS.

                (a)     Purchaser agrees that in entering upon and inspecting or
examining the Property and communicating with any Tenants, Purchaser and the
other Licensee Parties will not: disturb the Tenants or interfere with their use
of the Property pursuant to their respective Tenant Leases; interfere with the
operation and maintenance of the Property; damage any part of the Property or
any personal property owned or held by any Tenant or any other person or entity;
injure or otherwise cause bodily harm to Seller or any Tenant, or to any of
their respective agents, guests, invitees, contractors and employees, or to any
other person or entity; permit any liens to attach to the Property by reason of
the exercise of Purchaser's rights under this Article V; communicate with the
Tenants or service providers without Seller's prior written consent as provided
in this Article V; or, subject to the provisions of Section 17.16, reveal or
disclose any information obtained concerning the Property and the Documents to
anyone outside Purchaser's organization, except in accordance with the
confidentiality standards set forth in Section 5.2(b) and Article XII. Purchaser
will: (i) maintain and cause those entering the Property to maintain
comprehensive general liability (occurrence) insurance in terms (including
contractual indemnity coverage with respect to the indemnity in Section 5.3(b))
and amounts satisfactory to Seller covering any accident arising in connection
with the presence or activities of Purchaser or the other Licensee Parties on
the Property, and deliver to Seller a certificate of insurance verifying such
coverage and Seller being named as an additional insured on such coverage prior
to entry upon the Property; (ii) promptly pay when due the costs of all
inspections, entries, samplings and tests and examinations done with regard to
the Property; and (iii) promptly restore the Property to its condition as
existed immediately prior to any such inspection, investigations, examinations,
entries, samplings and tests, but in no event later than ten (10) days after the
damage occurs. Nothing contained in this Section 5.3 shall be deemed or
construed as Seller's consent to any further physical testing or sampling with
respect to the Property after the date hereof.

                (b)     Purchaser hereby indemnifies, defends and holds Seller
and its members, partners, agents, officers, directors, employees, successors,
assigns and Affiliates harmless from and against any and all liens, claims,
causes of action, damages, liabilities, demands, suits, and obligations,
together with all losses, penalties, costs and expenses relating to any of the
foregoing (including but not limited to court costs and reasonable attorneys'
and consultants' fees) arising

                                       15
<PAGE>

out of any inspections, investigations, examinations, entries, samplings or
tests conducted by Purchaser or any Licensee Party, whether prior to or after
the date hereof, with respect to the Property or any violation of the provisions
of this Section 5.3.

                (c)     Notwithstanding any provision of this Agreement to the
contrary, neither the Closing nor a termination of this Agreement will terminate
Purchaser's obligations pursuant to this Section 5.3.

        SECTION 5.4     RIGHT OF TERMINATION. Seller agrees that in the event
Purchaser determines in Purchaser's sole discretion, that the Property is not
suitable for its purposes, or that it is in the interest of Purchaser to
terminate this Agreement for any other reason, then Purchaser shall have the
right to terminate this Agreement by sending written notice thereof (the "Notice
of Termination") to Seller prior to the expiration of the Inspection Period.
Upon delivery by Purchaser of such Notice of Termination within the Inspection
Period, this Agreement shall terminate and the Earnest Money Deposit shall be
returned to Purchaser (and the Independent Consideration paid to Seller). If
Purchaser fails to send Seller a Notice of Termination prior to the expiration
of the Inspection Period, Purchaser shall no longer have any right to terminate
this Agreement under this Section 5.4.

WARRANTY OR ASSURANCE WHATSOEVER TO PURCHASER AND NO WARRANTIES OR
REPRESENTATIONS OF ANY KIND OR CHARACTER, EITHER EXPRESS OR IMPLIED, ARE MADE BY

(g) THE COMPLIANCE OR LACK THEREOF OF THE REAL PROPERTY OR THE IMPROVEMENTS WITH
GOVERNMENTAL REGULATIONS, IT BEING THE EXPRESS INTENTION OF SELLER AND PURCHASER
THAT, EXCEPT AS EXPRESSLY SET FORTH TO THE CONTRARY IN SECTION 8.1 OF THIS
AGREEMENT (AS LIMITED BY SECTION 16.1 OF THIS AGREEMENT), THE PROPERTY WILL BE
CONVEYED AND TRANSFERRED TO PURCHASER IN ITS PRESENT CONDITION AND STATE OF
REPAIR, "AS IS" AND "WHERE IS", WITH ALL FAULTS. Purchaser represents that it is
a knowledgeable, experienced and sophisticated purchaser of real estate, and
that it is relying solely on its own expertise and that of Purchaser's
consultants in purchasing the Property. Purchaser has conducted prior to the
date hereof, or will conduct during the Inspection Period, such inspections,
investigations and other independent examinations of the Property and related
matters as Purchaser deems necessary, including but not limited to the physical
and environmental conditions thereof, and will rely upon same and not upon any
statements of Seller (excluding the limited specific matters represented by
Seller in Section 8.1 hereof as limited by Section 16.1 of this Agreement) or of
any Affiliate, officer, director, employee, agent or attorney of Seller.
Purchaser acknowledges that all information obtained by Purchaser was obtained
from a variety of sources and Seller will not be deemed to have represented or
warranted the completeness, truth or accuracy of any of the Documents or other
such information heretofore or hereafter furnished to Purchaser, except as
expressly provided in this Agreement. Upon Closing, Purchaser will assume the
risk that adverse matters, including, but not limited to, adverse physical and
environmental conditions, may not have been revealed by Purchaser's inspections
and investigations. Purchaser further hereby assumes the risk of changes in
applicable Environmental Laws relating to past, present and future environmental
health conditions on, or resulting from the ownership or operation of, the
Property. Purchaser acknowledges and agrees that upon Closing, Seller will sell
and convey to Purchaser, and Purchaser will accept the Property, "AS IS, WHERE
IS," with all faults. Purchaser further acknowledges and agrees that there are
no oral agreements, warranties or representations, collateral to or affecting
the Property, by Seller, an Affiliate of Seller, any agent of Seller or any
third party. Seller is not liable or bound in any manner by any oral or written
statements, representations or information pertaining to the Property furnished
by any real estate broker, agent, employee, servant or other person, unless the
same are specifically set forth or referred to herein. Purchaser acknowledges
that the Purchase Price reflects the "AS IS, WHERE IS" nature of this sale and
any faults, liabilities, defects or other adverse matters that may be associated
with the Property. Purchaser, with Purchaser's counsel, has fully reviewed the
disclaimers and waivers set forth in this Agreement, and understands the
significance and effect thereof. Purchaser acknowledges and agrees that the
disclaimers and other agreements set forth herein are an integral part of this
Agreement, and that Seller would not have agreed to sell the Property to
Purchaser for the Purchase Price without the disclaimer and other agreements set
forth in this Agreement. The terms and conditions of this Section 5.5 will
expressly survive the Closing and will not merge with the provisions of any
closing documents.

        SECTION 5.6     PURCHASER'S RELEASE OF SELLER.

                (a)     SELLER RELEASED FROM LIABILITY. Purchaser, on behalf of
itself and its partners, officers, directors, agents, controlling persons and
Affiliates, hereby releases Seller and Seller's Affiliates from any and all
liability, responsibility, causes of action, claims or demands, whether direct
or indirect, known or unknown, accrued or contingent, arising out of or related
to the condition (including the presence in the soil, air, structures and
surface and subsurface waters, of Hazardous Substances that have been or may in
the future be determined to be toxic, hazardous, undesirable or subject to
regulation and that may need to be specially treated, handled and/or removed
from the Property under current or future federal, state and local laws,
regulations or guidelines), valuation, salability or utility of the Property, or
its suitability for any purpose whatsoever except to the extent that such
responsibility or liability is the result of the material inaccuracy (if any) of
Seller's representation under Section 8.1(j) hereof (as limited by Section 16.1
of this Agreement). Without limiting the foregoing, Purchaser specifically
releases Seller and Seller's Affiliates from any claims Purchaser may have
against Seller and/or Seller's Affiliates now or in the future arising from the
environmental, health or safety condition of the Property or the presence of
Hazardous Substances or contamination on or emanating from the Property. The
foregoing waivers and releases by Purchaser shall survive either (i) the Closing
and shall not be deemed merged into the provisions of any closing documents, or
(ii) any termination of this Agreement.

                                                        ________________________
                                                              Purchaser Initials

                (b)     PURCHASER'S WAIVER OF OBJECTIONS. Purchaser acknowledges
that it has prior to the date hereof, or will during the Inspection Period,
inspect the Property, observe its physical characteristics and existing
conditions and conduct such investigations and studies on the Property and
adjacent areas as it deems necessary, and subject only to Seller's
responsibility for any breach of the warranty and representation contained in
Section 8.1(j) of this Agreement (as limited by Section 16.1 of this Agreement),
Purchaser hereby waives any and all objections to or complaints (including but
not limited to actions based on federal, state or common law and any private
right of action under CERCLA, RCRA or any other state and federal law to which
the Property is or may be subject) against Seller, its Affiliates, or their
respective officers, directors, partners, members, owners, employees or agents
regarding physical characteristics and existing conditions, including without
limitation structural and geologic conditions, subsurface soil and water
conditions and solid and hazardous waste and Hazardous Substances on, under,
adjacent to or otherwise affecting the Property or related to prior uses of the
Property.

                (c)     ASSUMPTION OF RISK. Purchaser further hereby assumes the
risk of changes in applicable laws and regulations relating to past, present and
future environmental, safety or health conditions on, or resulting from the
ownership or operation of, the Property, and the risk that adverse physical
characteristics and conditions, including without limitation the presence of
Hazardous Substances or other substances, may not be revealed by its
investigation.

                (d)     SURVIVAL. The provisions of this Section 5.6 shall
survive either (i) the Closing and shall not be deemed merged into the
provisions of any closing documents, or (ii) any termination of this Agreement.

        SECTION 5.7     HAZARDOUS MATERIALS. If, subsequent to the execution of
this Agreement, Seller obtains knowledge of, or Purchaser's inspection of the
Property reveals the presence of any Hazardous Materials or the violation or
potential violation of any Environmental Law at, on or under the Property
(collectively, a "DEFECTIVE CONDITION"), which Seller, in its sole judgment,
determines could constitute a potential liability to Seller after the Closing or
should be remedied prior to the sale of the Property, Seller shall have the
right upon written notice to Purchaser on or before the Closing Date either (i)
to extend the Closing Date for the period of time necessary to complete such
remediation at Seller's sole cost and expense, or (ii) to terminate this
Agreement upon written notice to Purchaser, in which event the Earnest Money
Deposit shall be refunded to Purchaser, and thereafter neither Seller nor
Purchaser will have any further rights or obligations to the other hereunder
except with respect to the Termination Surviving Obligations. Purchaser
understands that Seller may elect in its sole discretion to obtain its own new
or updated environmental assessments at Seller's cost in furtherance of its
rights under this Section 5.7. The terms of this Section 5.7 are solely for the
benefit of Seller. Purchaser shall have no additional right or remedy hereunder
as a result of the exercise by Seller of its rights under this Section 5.7.

                                   ARTICLE VI
                            TITLE AND SURVEY MATTERS

        SECTION 6.1     SURVEY. No later than two (2) Business Days after the
execution and delivery of this Agreement, Seller will deliver to Purchaser's
counsel (if not delivered to Purchaser prior to the date hereof) a copy of that
certain survey of the Real Property, dated January 7, 2003, last revised July
31, 2003, prepared by Frontline Surveying and Mapping, Inc. (the "EXISTING
SURVEY"). Seller shall have no obligation to obtain any modification, update, or
recertification of the Existing Survey.

        SECTION 6.2     TITLE COMMITMENT.

                (a)     Purchaser shall cause the Title Company to furnish to
Purchaser a preliminary title report or title commitment(the "COMMITMENT"), by
the terms of which the Title Company agrees to issue to Purchaser at Closing an
owner's policy of title insurance (the "TITLE POLICY") in the amount of the
Purchase Price on the ALTA Owner Policy of Title Insurance with extended
coverage, Standard Form Rev. 10/17/92 (as amended to date) insuring Purchaser's
fee simple title to the Real Property to be good and indefeasible, subject to
the terms of such policy and the exceptions described therein. Subject to
Section 6.2(b), all matters shown on the Existing Survey and exceptions listed
in the Commitment are conclusively deemed to be acceptable to Purchaser. The
term "PERMITTED EXCEPTIONS" means taxes and assessments for the year of Closing
and for any other year if not yet due and payable as of Closing and all matters
either shown on the Existing Survey or listed in the Commitment. The Title
Policy may be delivered after Closing if at the Closing the Title Company issues
a currently effective, duly executed "marked up" Commitment and irrevocably
commits in writing to issue the Title Policy in the form of the "marked up"
Commitment promptly after the Closing Date.

                                       19
<PAGE>

                (b)     Notwithstanding any provision of this Section 6.2 to the
contrary, Seller will be obligated to cure exceptions to title to the Real
Property and Improvements relating to (or, as to (ii), cure or cause deletion
from the Title Policy or affirmative title insurance over) (i) liens and
security interests securing any loan to Seller, and (ii) any other liens or
security interests created by documents executed by Seller to secure monetary
obligations, other than liens for ad valorem taxes and assessments.

                                  ARTICLE VII
                    INTERIM OPERATING COVENANTS AND ESTOPPELS

        SECTION 7.1     INTERIM OPERATING COVENANTS. Seller covenants to
Purchaser that Seller will:

                (a)     OPERATIONS. From the Effective Date until Closing,
continue to operate, manage and maintain the Improvements in the ordinary course
of Seller's business and substantially in accordance with Seller's present
practice, subject to ordinary wear and tear and further subject to Article IX of
this Agreement.

                (b)     MAINTAIN INSURANCE. From the Effective Date until
Closing, maintain fire and extended coverage insurance on the Improvements which
is at least equivalent in all material respects to Seller's insurance policies
covering the Improvements as of the Effective Date.

                (c)     PERSONAL PROPERTY. From the Effective Date until
Closing, not transfer or remove any Personal Property from the Improvements
except for the purpose of repair or replacement thereof. Any items of Personal
Property replaced after the Effective Date will be installed prior to Closing
and will be of substantially similar quality of the item of Personal Property
being replaced.

                (d)     COMPLY WITH GOVERNMENTAL REGULATIONS. From the Effective
Date until Closing, not knowingly take any action that Seller knows would result
in a failure to comply in all material respects with all Governmental
Regulations applicable to the Property, it being understood and agreed that
prior to Closing, Seller will have the right to contest any such Governmental
Regulations.

                (e)     LEASES. From the Effective Date until Closing, not enter
into any new lease or any amendments, expansions or renewals of Tenant Leases
without the prior written consent of Purchaser, which consent will not be
unreasonably withheld, delayed or conditioned, and will be deemed given unless
written objection thereto is given within two (2) Business Days after receipt of
the relevant information. Furthermore, nothing herein shall be deemed to require
Purchaser's consent to any expansion or renewal which Landlord is required to
honor pursuant to any Lease.

                (f)     SERVICE CONTRACTS. From the Effective Date until
Closing, not enter into any service contract other than in the ordinary course
of business, unless such service contract is terminable on thirty (30) days
notice without penalty or unless Purchaser consents thereto in writing, which
approval will not be unreasonably withheld, delayed or conditioned.

                                       20
<PAGE>

                (g)     NOTICES. To the extent received by Seller, from the
Effective Date until Closing, promptly deliver to Purchaser copies of written
default notices, notices of lawsuits and notices of violations affecting the
Property.

                (h)     UBTI AGREEMENTS. Notwithstanding anything contained in
this Agreement to the contrary, if, during the Inspection Period, Purchaser
notifies Seller in writing that any existing agreement affecting the Property
(including, without limitation, any agreement in respect to the parking facility
included in the Improvements) might, if assigned to Purchaser, cause Purchaser
to incur unrelated business taxable income under the Internal Revenue Code of
1986, as amended (a "UBTI AGREEMENT"), then Seller shall cause such UBTI
Agreement to be terminated at or prior to Closing, to the extent that such UBTI
Agreement permits termination by Seller by Closing without the payment of any
penalty or termination fee.

        SECTION 7.2     ESTOPPELS.

                (a)     It will be a condition to Closing that Seller obtain and
deliver to Purchaser, from each of the major tenants listed on EXHIBIT D-1
("MAJOR TENANTS") and other Tenants leasing space which when added to the Major
Tenants aggregates at least 75% of the leased space at the Improvements,
executed estoppel certificates, with no material modifications from the estoppel
certificate form attached hereto as EXHIBIT D-2; provided, however, (i) to the
extent that the form as so completed requires information not required of a
Tenant under the provisions of its Tenant Lease, Seller will exercise good faith
efforts to obtain an estoppel certificate for such Tenant in the form completed
as provided below, or in a form as close thereto as reasonably possible, but in
any event an estoppel certificate executed by a Tenant in the form prescribed by
its Tenant Lease shall satisfy the requirement of this Section 7.2(a), and (ii)
Purchaser will not unreasonably withhold approval of any estoppel certificate as
modified by a Tenant and delivered by Seller to Purchaser, provided that the
information included in such estoppel is not inconsistent with the information
included in the estoppel form completed for such Tenant pursuant to the below
provisions of this Section 7.2(a). Within five (5) Business Days after the
Effective Date, Seller will deliver to Purchaser completed forms of estoppel
certificates, in the form attached hereto as EXHIBIT D-2 and containing the
information contemplated thereby, for all Tenants. Within five (5) Business Days
following Purchaser's receipt thereof, Purchaser will send to Seller notice
either (i)approving such forms as completed by Seller or (ii) setting forth in
detail all changes to such forms which Purchaser believes to be appropriate to
make the completed forms of estoppel certificates accurate and complete. Seller
will make such changes to the extent Seller agrees such changes are appropriate,
except that Seller will not be obligated to make any changes which request more
expansive information than is contemplated by EXHIBIT D-2. Seller will then
circulate the tenant estoppels to the Tenants and exercise good faith efforts to
obtain execution of same by the Tenants. Seller shall deliver each estoppel
certificate executed by a Tenant (whether or not in compliance herewith) to
Purchaser promptly following Seller's receipt thereof. Notwithstanding anything
contained herein to the contrary, in no event shall Seller's failure to obtain
the required number of acceptable estoppel certificates in accordance with the
provisions of this Section 7.2(a) constitute a default by Seller under this
Agreement.

                (b)     Seller, at its sole option, may elect to satisfy part of
the requirements under Section 7.2(a) by delivering a representation certificate
of Seller in the form attached

                                       21
<PAGE>

hereto as EXHIBIT E (a "SELLER Certificate") for up to 10% of the space leased
by non- Major Tenants. If Seller subsequently obtains an estoppel certificate
meeting the requirements of Section 7.2(a) hereof, from a Tenant for which
Seller has delivered a Seller Certificate, the delivered Seller Certificate will
be null and void, and Purchaser will accept such estoppel certificate in its
place.

                (c)     If, as of the fifth (5th) day prior to the Closing Date,
Seller has not obtained and furnished to Purchaser executed estoppel
certificates (or a combination of executed estoppel certificates and Seller
Certificates permitted under Section 7.2(b) above) sufficient to satisfy the
condition set forth in Section 7.2(a), then Purchaser may (i) waive the
foregoing condition precedent and proceed to Closing; or (ii) terminate this
Agreement, in which event the Earnest Money Deposit (less the Independent
Consideration, which shall be paid over to Seller) shall be returned to
Purchaser and neither Seller nor Purchaser will have any further obligation
under this Agreement except for the Termination Surviving Obligations.

                                  ARTICLE VIII
                         REPRESENTATIONS AND WARRANTIES

                (a)     STATUS. Seller is a limited liability company duly
organized and validly existing under the laws of the State of Delaware.

                (b)     AUTHORITY. The execution and delivery of this Agreement
and the performance of Seller's obligations hereunder have been or will be duly
authorized by all necessary action on the part of Seller, and this Agreement
constitutes the legal, valid and binding obligation of Seller, subject to
equitable principles and principles governing creditors' rights generally.

                (c)     NON-CONTRAVENTION. The execution and delivery of this
Agreement by Seller and the performance by Seller of Seller's obligations under
this Agreement will not violate any judgment, order, injunction, decree,
regulation or ruling of any court or Authority or conflict with, result in a
breach of, or constitute a default under the organizational documents of Seller,
any note or other evidence of indebtedness, any mortgage, deed of trust or
indenture, or any lease or other material agreement or instrument to which
Seller is a party or by which it is bound.

                (d)     SUITS AND PROCEEDINGS. To Seller's Knowledge as of the
Effective Date, except as listed in EXHIBIT F, there are no legal actions, suits
or similar proceedings pending and served, or threatened against Seller relating
to the Property or Seller's ownership or operation of the Property, which are
not adequately covered by existing insurance or, if adversely determined, would
materially adversely affect the value of the Property, the continued operations
thereof or Seller's ability to perform Seller's obligations under this
Agreement.

<PAGE>

                (e)     NON-FOREIGN ENTITY. Seller is not a "foreign person" or
"foreign corporation" as those terms are defined in the Internal Revenue Code of
1986, as amended, and the regulations promulgated thereunder.

                (f)     TENANTS. To Seller's Knowledge as of the Effective Date,
the list of Tenants, as set forth on EXHIBIT G attached hereto, constitutes all
of the Tenants from whom Seller is currently accepting rental payments. To
Seller's Knowledge, there are no written leases or occupancy agreements
affecting the Real Property or Improvements to which Seller is a party and bound
with any parties other than the Tenants listed on EXHIBIT G.

                (h)     NO VIOLATIONS. To Seller's Knowledge, Seller has not
received prior to the Effective Date any written notification from an Authority
(i) that the Real Property and Improvements is in violation of any applicable
fire, health, building, use, occupancy or zoning laws or (ii) that any work is
required to be done to the Real Property and Improvements where such work
remains outstanding and, if unaddressed would have a material adverse affect on
the Property or use of the Property as currently operated.

                (i)     INSURANCE. To Seller's Knowledge, Seller has not
received any written notice from any insurance company or board of fire
underwriters of any defects or inadequacies in or on the Improvements or any
part or component thereof that would adversely affect the insurability of the
Improvements or cause any increase in the premiums for insurance for the
Improvements.

                (j)     ENVIRONMENTAL. Except as shown in any environmental
reports covering the Real Property and Improvements which have been made
available to Purchaser pursuant to Section 5.2(a), to Seller's Knowledge, Seller
has not received written notice from any Authorities of the Real Property or
Improvements being in violation of any Environmental Law.

                (k)     LEASING COMMISSIONS. To Seller's knowledge, all leasing
commissions which are attributable to the execution of Tenant Leases existing as
of the Effective Date or the move-in of tenants occupying the Property as of the
Effective Date have been paid in full; provided, however, no representation is
made with respect to leasing commissions due in connection with amendments,
modifications, extensions, expansions or renewals of the Tenant Leases or with
respect to commissions due in connection with the failure by a tenant to
exercise an early termination option.

                (l)     MANAGEMENT AGREEMENTS. Any and all property management
contracts and leasing agreements with respect to the Property shall be
terminated by Seller effective as of the Closing, with Seller having fully paid
and discharged any and all obligations accruing thereunder.

which Purchaser is a party or by which it is bound.

                (d)     CONSENTS. No consent, waiver, approval or authorization

                                   ARTICLE IX
                            CONDEMNATION AND CASUALTY

        SECTION 9.1     SIGNIFICANT CASUALTY. If, prior to the Closing Date, all
or a Significant Portion of the Real Property and Improvements is destroyed or
damaged by fire or other casualty, Seller will notify Purchaser of such
casualty. Purchaser will have the option to terminate this Agreement upon notice
to Seller given not later than ten (10) days after receipt of Seller's notice.
If this Agreement is terminated, the Earnest Money Deposit will be returned to
Purchaser upon Purchaser's compliance with Section 4.5 and thereafter neither
Seller nor Purchaser will have any further rights or obligations to the other
hereunder except with respect to the Termination Surviving Obligations. If
Purchaser does not elect to terminate this Agreement, Seller will not be
obligated to repair such damage or destruction but (a) Seller will assign and
turn over to Purchaser all of the insurance proceeds net of reasonable
collection costs (or, if such have not been awarded, all of its right, title and
interest therein) payable with respect to such fire or other casualty, and (b)
the parties will proceed to Closing pursuant to the terms hereof without
abatement of the Purchase Price, except that Purchaser will receive a credit for
the lesser of (i) any insurance deductible amount, or (ii) the cost of such
repairs (other than repairs which are the responsibility of Tenants under Tenant
Leases) as reasonably estimated by Seller.

        SECTION 9.2     CASUALTY OF LESS THAN A SIGNIFICANT PORTION. If less
than a Significant Portion of the Real Property and Improvements is damaged as
aforesaid, Purchaser shall not have the right to terminate this Agreement and
Seller will not be obligated to repair such damage or destruction but (a) Seller
will assign and turn over to Purchaser all of the insurance proceeds net of
reasonable collection costs (or, if such have not been awarded, all of its
right, title and interest therein) payable with respect to such fire or other
casualty, and (b) the parties will proceed to Closing pursuant to the terms
hereof without abatement of the Purchase Price, except that Purchaser will
receive a credit for the lesser of (i) any insurance deductible amount, or (ii)
the cost of such repairs (other than repairs which are the responsibility of
Tenants under Tenant Leases) as reasonably estimated by Seller.

        SECTION 9.3     CONDEMNATION OF PROPERTY. In the event of condemnation
or sale in lieu of condemnation of all or any portion of the Real Property and
Improvements prior to the Closing, Purchaser will have the option, by providing
Seller written notice within ten (10) days after receipt of Seller's notice of
such condemnation or sale, of terminating Purchaser's obligations under this
Agreement or electing to have this Agreement remain in full force and effect. In
the event Purchaser does not terminate this Agreement pursuant to the preceding
sentence, Seller will assign to Purchaser any and all claims for the proceeds of
such condemnation or sale to the extent the same are applicable to the Real
Property and Improvements, and Purchaser will take title to the Property with
the assignment of such proceeds and subject to such condemnation and without
reduction of the Purchase Price. Should Purchaser elect to terminate Purchaser's
obligations under this Agreement under the provisions of this Section 9.3, the
Earnest Money Deposit will be returned to Purchaser upon Purchaser's compliance
with Section 4.5 and neither Seller nor Purchaser will have any further
obligation under this Agreement except for the Termination Surviving
Obligations. Notwithstanding anything to the contrary herein, if any eminent
domain or condemnation proceeding is instituted (or notice of same is given)
solely for the taking of any subsurface rights for utility easements or for any
right-of-way easement, and the surface may, after such taking, be used in
substantially

                                       25
<PAGE>

the same manner as though such rights have not been taken, Purchaser will not be
entitled to terminate this Agreement as to any part of the Property, but any
award resulting therefrom will be assigned to Purchaser at Closing and will be
the exclusive property of Purchaser upon Closing.

                                   ARTICLE X
                                     CLOSING

        SECTION 10.1    CLOSING. The Closing of the sale of the Property by

Article X will occur, it being understood that the performance or tender of
performance of all matters set forth in this Article X are mutually concurrent
conditions which may be waived by the party for whose benefit they are intended.

        SECTION 10.2    PURCHASER'S CLOSING OBLIGATIONS. At least one (1)

Section 4.3, for delivery to Seller at Closing as provided herein:

appropriate to effect the consummation of the transactions which are the subject
of this Agreement.

        SECTION 10.3    SELLER'S CLOSING OBLIGATIONS. Seller, at its sole cost
and expense, will deliver (y) the following items (a), (b), (c), (d), (e), (f),
(g), (i), (l) and (m) in escrow with the Title Company pursuant to Section 4.3,

                                       26

                (b)     The General Conveyance duly executed by Seller;

                (c)     The Tenant Notice Letters, duly executed by Seller;

                (e)     A certificate in the form attached hereto as EXHIBIT K
("CERTIFICATE AS TO FOREIGN STATUS") certifying that Seller is not a "foreign
person" as defined in Section 1445 of the Internal Revenue Code of 1986, as

                (f)     The Tenant Deposits, at Seller's option, either (i) in
the form of a cashier's check issued by a bank reasonably acceptable to
Purchaser, or (ii) as part of an adjustment to the Purchase Price. In the event
the Tenant Deposits are in the form of a letter of credit, then Seller shall
deliver at Closing the original letter(s) of credit, together with documentation
sufficient to cause the letter(s) of credit to be assigned to Purchaser upon
approval thereof by the issuer of the letter(s) of credit;

                (g)     A certification meeting the requirements of O.C.G.A.

                (i)     The Rent Roll, updated to show any changes, to Seller's

                (m)     Such other documents as may be reasonably necessary or
appropriate to effect the consummation of the transactions which are the subject
of this Agreement.

        SECTION 10.4    PRORATIONS.

                (a)     Seller and Purchaser agree to adjust, as of 11:59 p.m.
on the day immediately preceding the Closing Date (the "CLOSING TIME"), the
following (collectively, the "PRORATION ITEMS"): real estate and personal
property taxes and assessments which are required to be paid for the calendar
year in which the Closing occurs, utility bills (except as hereinafter
provided), collected Rentals (subject to the terms of (c) below) and operating
expenses payable by the owner of the Property. Seller will be charged and
credited for the amounts of all of the Proration Items relating to the period up
to and including the Closing Time, and Purchaser will

                                       27
<PAGE>

be charged and credited for all of the Proration Items relating to the period
after the Closing Time. Such preliminary estimated Closing prorations shall be
set forth on a preliminary closing statement to be prepared by Seller and
submitted to Purchaser for Purchaser's approval (which approval shall not be
unreasonably withheld, delayed or conditioned) five (5) days prior to the
Closing Date (the "CLOSING STATEMENT"). The Closing Statement, once agreed upon,
shall be signed by Purchaser and Seller and delivered to the Title Company for
purposes of making the preliminary proration adjustment at Closing subject to
the final cash settlement provided for below. The preliminary proration shall be
paid at Closing by Purchaser to Seller (if the preliminary prorations result in
a net credit to Seller) or by Seller to Purchaser (if the preliminary prorations
result in a net credit to Purchaser) by increasing or reducing the cash to be
delivered by Purchaser in payment of the Purchase Price at the Closing. If the
actual amounts of the Proration Items are not known as of the Closing Time, the
prorations will be made at Closing on the basis of the best evidence then
available; thereafter, when actual figures are received, re-prorations will be
made on the basis of the actual figures, and a final cash settlement will be
made between Seller and Purchaser. No prorations will be made in relation to
insurance premiums (except to the extent covered by the proration of Operating
Expense Recoveries), and Seller's insurance policies will not be assigned to
Purchaser. Final readings and final billings for utilities will be made if
possible as of the Closing Time, in which event no proration will be made at the
Closing with respect to utility bills (except to the extent covered by the
proration of Operating Expense Recoveries). Seller will be entitled to all
deposits presently in effect with the utility providers, and Purchaser will be
obligated to make its own arrangements for deposits with the utility providers.
A final reconciliation of Proration Items shall be made by Purchaser and Seller
within six (6) months of Closing, except to the extent that sufficient property
tax or other information is not available at such time to make a final
adjustment of Proration Items, in which event such adjustments will be made as
soon as reasonably practicable after such information is made available. The
provisions of this Section 10.4 (excluding subsection (e) which is governed by
Section 3.2(a) above) will survive the Closing for twelve (12) months.

                (b)     Purchaser will receive a credit on the Closing Statement
for the prorated amount (as of the Closing Time) of all Rentals previously paid
to and collected by Seller and attributable to any period following the Closing
Time. After the Closing, Seller will cause to be paid or turned over to
Purchaser all Rentals, if any, received by Seller after Closing and properly
attributable to any period following the Closing Time. "RENTALS" as used herein
includes fixed monthly rentals, additional rentals, percentage rentals,
escalation rentals (which include each Tenant's proportionate share of building
operation and maintenance costs and expenses as provided for under the
applicable Tenant Lease, to the extent the same exceeds any expense stop
specified in such Tenant Lease), retroactive rentals, all administrative
charges, utility charges, tenant or real property association dues, storage
rentals, special event proceeds, temporary rents, telephone receipts, locker
rentals, vending machine receipts and other sums and charges payable to Seller
or its successor by tenants under the Tenant Leases or from other occupants or
users of the Property, excluding specific tenant billings which are governed by
Section 10.4(d) below. Rentals are "DELINQUENT" if they were due prior to the
Closing Time and payment thereof has not been made on or before the Closing
Time. Delinquent Rentals will not be prorated. Purchaser agrees to use good
faith collection procedures with respect to the collection of any Delinquent
Rentals, but Purchaser will have no liability for the failure to collect any
such amounts and will not be required to conduct lock-outs or take any other
legal action to enforce collection of any such amounts owed to Seller by Tenants
of the Property. All sums collected by

                                       28
<PAGE>

Purchaser from and after Closing from each Tenant (excluding Tenant payments for
Operating Expense Recoveries attributable to the period prior to the Closing
Time governed by Section 10.4(c) below and tenant specific billings for tenant
work orders and other specific services as described in and governed by Section
10.4(d) below) will be applied first to current amounts owed by such Tenant to
Purchaser and then to prior delinquencies owed by such Tenant to Seller. Any
sums collected by Purchaser and due Seller will be promptly remitted to Seller.
Notwithstanding the foregoing, however, after the Closing Date Seller may
collect Delinquent Rentals, amounts owed for Operating Expense Recoveries and
billings for tenant work orders directly from Tenants, provided, however, in no
event will Seller have the right to threaten termination of any Tenant Lease.

                (c)     Seller will prepare a reconciliation as of the Closing
Time of the amounts of all billings and charges for operating expenses and taxes
in excess of the applicable expense stop, if any, specified in each Tenant Lease
(collectively, "OPERATING EXPENSE RECOVERIES") for calendar year 2004. If less
amounts have been collected from Tenants for Operating Expense Recoveries for
calendar year 2004 than would have been owed by Tenants under the Tenant Leases
if the reconciliations under such Tenant Leases were completed as of the Closing
Time based on the operating expenses and taxes incurred by Seller for calendar
year 2004 up to the Closing Time (as prorated pursuant to Section 10.4(a)
above), Purchaser will pay such difference to Seller at Closing as an addition
to the Purchase Price. If more amounts have been collected from Tenants for
Operating Expense Recoveries for calendar year 2004 than would have been owed by
Tenants under the Tenant Leases if the reconciliations under such Tenant Leases
were completed as of the Closing Time based on the operating expenses and taxes
incurred by Seller for calendar year 2004 up to the Closing Time (as prorated
pursuant to Section 10.4(a) above), Seller will pay to Purchaser at Closing as a
credit against the Purchase Price such excess collected amount. Purchaser and
Seller agree that such proration of Operating Expense Recoveries at Closing for
calendar year 2004 will fully relieve Seller from any responsibility to Tenants
or Purchaser for such matters subject to Seller's and Purchaser's right and
obligation to finalize prorations within one hundred twenty (120) days after
Closing solely to make adjustments necessary to the extent estimates used in the
calculation of such reconciliation at Closing differ from actual bills received
after Closing for those items covered by such reconciliation at Closing or to
correct any errors. In this regard, Purchaser will be solely responsible, from
and after Closing, for (i) collecting from Tenants the amount of any outstanding
Operating Expense Recoveries for calendar year 2004 for periods before and after
Closing, and (ii) where appropriate, reimbursing Tenants for amounts
attributable to Operating Expense Recoveries for calendar year 2004, as may be
necessary based on annual reconciliations for Operating Expense Recoveries for
such calendar year.

                (d)     With respect to specific tenant billings for work
orders, special items performed or provided at the request of a given Tenant or
other specific services, which are collected by Purchaser or Seller after the
Closing Time but relate to any such specific services rendered by Seller or its
property manager prior to the Closing Time and which are identified on the
Tenant's payment as relating to such specific services or which are clearly
identifiable as being payment for any such specific services, Purchaser shall
cause such collected amounts to be paid to Seller, or Seller may retain such
payment if such payment is received by Seller after the Closing Time.

                                       29
<PAGE>

                (e)     Notwithstanding any provision of this Section 10.4 to
the contrary, Purchaser will be solely responsible for all leasing commissions,
brokerage commissions, tenant improvement allowances, legal fees and other
expenditures incurred in connection with the lease of space in the Property
("LEASING COSTS") to the extent unpaid as of the Closing Date and becoming due
and payable after Closing under or with respect to Tenant Leases entered into
prior to the Effective Date, including, without limitation, Leasing Costs
pertaining to amendments, modifications, expansions, extensions, renewals of, or
failure to exercise termination options under, Tenant Leases becoming effective
after the Effective Date. Subject to any approval rights which Purchaser may
have pursuant to Section 7.1(e) of this Agreement, Purchaser further agrees to
be solely responsible for all Leasing Costs (for purposes of this Section
10.4(e), "NEW TENANT COSTS") incurred or to be incurred in connection with any
new Tenant Lease executed on or after the Effective Date, and Purchaser will pay
to Seller at Closing as an addition to the Purchase Price an amount equal to any
New Tenant Costs paid by Seller prior to Closing.

        SECTION 10.5    DELIVERY OF REAL PROPERTY. Upon completion of the
Closing, Seller will deliver to Purchaser possession of the Real Property and
Improvements, subject to the Tenant Leases and the Permitted Exceptions.

        SECTION 10.6    COSTS OF TITLE COMPANY AND CLOSING COSTS. Costs of the
Title Company and other Closing costs incurred in connection with the Closing
will be allocated as follows:

                (a)     Purchaser will pay (i) all premium and other costs for
the Title Policy and any endorsements thereto, (ii) all premiums and other costs
for any mortgagee policy of title insurance, including but not limited to any
endorsements or deletions, (iii) the costs associated with any modifications,
updates, or recertifications of the Existing Survey, (iv) Purchaser's attorney's
fees; (v) 1/2 of all of the Title Company's escrow and closing fees, if any,
(vi) any intangibles tax imposed as result of Purchaser's financing, (vii) any
prepayment premium and associated fees actually required by The Travelers
Insurance Company to be paid at Closing as a result of the repayment of the
Traveler's Loan (collectively, the "PREPAYMENT PREMIUM"), and (viii) all
recording fees other than that of the Deed;

                (b)     Seller will pay (i) transfer tax resulting from the
conveyance of the Property, (ii) 1/2 of all of the Title Company's escrow and
closing fees, (iii) Seller's attorneys' fees and (iv) all recording fees imposed
on the Deed;

                (c)     Any other costs and expenses of Closing not provided for
in this Section 10.6 shall be allocated between Purchaser and Seller in
accordance with the custom in the county in which the Real Property is located;
and

                (d)     If the Closing does not occur on or before the Closing
Date for any reason whatsoever, the costs incurred through the date of
termination will be borne by the party incurring same.

        SECTION 10.7    POST-CLOSING DELIVERY OF TENANT NOTICE LETTERS.
Immediately following Closing, Purchaser will deliver to each Tenant (via
messenger or certified mail, return receipt requested) a written notice executed
by Purchaser and Seller (i) acknowledging the sale of the

                                       30
<PAGE>

Property to Purchaser, (ii) acknowledging that Purchaser has received and is
responsible for the Tenant Deposits (specifying the exact amount of the Tenant
Deposits) and (iii) indicating that rent should thereafter be paid to Purchaser
and giving instructions therefor (the "TENANT NOTICE LETTERS"). Purchaser shall
provide to Seller a copy of each Tenant Notice Letter promptly after delivery of
same, and proof of delivery of same promptly after such proof is available. This
Section 10.7 shall survive Closing.

                                   ARTICLE XI
                                    BROKERAGE

        SECTION 11.1    BROKERS. Seller agrees to pay to CB Richard Ellis, a
Georgia licensed real estate broker ("BROKER"), a real estate commission at
Closing (but only in the event of Closing in strict compliance with this
Agreement) pursuant to a separate agreement. The payment of the commission by
Seller to Broker will fully satisfy the obligations of the Seller for the
payment of a real estate commission hereunder. Other than as stated in the first
sentence of this Section 11.1, Purchaser and Seller represent to the other that
no real estate brokers, agents or finders' fees or commissions are due or will
be due or arise in conjunction with the execution of this Agreement or
consummation of this transaction by reason of the acts of such party, and
Purchaser and Seller will indemnify, defend and hold the other party harmless
from any brokerage or finder's fee or commission claimed by any person asserting
his entitlement thereto at the alleged instigation of the indemnifying party for
or on account of this Agreement or the transactions contemplated hereby. The
provisions of this Article XI will survive any Closing or termination of this
Agreement.

        SECTION 11.2    BROKER'S LIEN WAIVER. At least one (1) Business Day
prior to the Closing Date, Broker shall deliver to the Title Company a broker's
lien waiver which includes, without limitation, (a) an acknowledgment by Broker
of the receipt of the entire balance due to Broker for all services rendered by
Broker relating to the Land, (b) a waiver by Broker of any claim or lien which
Broker may have against Purchaser, Seller, or the Land by reason of the
transaction contemplated by this Agreement, and (c) an indemnity by Broker of
Seller and Purchaser from and against any such claim or lien which may be
asserted by any agent, broker or other intermediary by reason of any act or
agreement of Broker.

                                  ARTICLE XII
                                 CONFIDENTIALITY

        SECTION 12.1    CONFIDENTIALITY. Subject to the provisions of Section
17.16, Seller and Purchaser each expressly acknowledges and agrees that, unless
and until the Closing occurs, the transactions contemplated by this Agreement
and the terms, conditions, and negotiations concerning the same will be held in
the strictest confidence by each of them and will not be disclosed by either of
them except to their respective legal counsel, accountants, consultants,
officers, investors, clients, partners, directors, shareholders and lenders, and
except and only to the extent that such disclosure may be necessary for their
respective performances hereunder or as otherwise required by applicable law.
Purchaser further acknowledges and agrees that, except as provided in this
Section 12.1, in Section 5.2(b) and in Section 17.16, until the Closing occurs,
all information obtained by Purchaser in connection with the Property will not
be disclosed by Purchaser to any third persons without the prior written consent
of Seller. Nothing contained in

                                       31
<PAGE>

this Article XII will preclude or limit either party to this Agreement from
disclosing or accessing any information otherwise deemed confidential under this
Article XII that is (a) rightfully of public record or within the public domain,
or (b) in connection with that party's enforcement of its rights following a
disagreement hereunder, or in response to lawful process or subpoena or other
valid or enforceable order of a court of competent jurisdiction or any filings
with governmental authorities required by reason of the transactions provided
for herein pursuant to an opinion of counsel. To the extent of any conflict
between the terms of this Agreement and the terms of the Confidentiality
Agreement, the terms of this Agreement shall govern. The provisions of this
Article XII will survive any termination of this Agreement.

                                  ARTICLE XIII
                                    REMEDIES

        SECTION 13.1    DEFAULT BY SELLER. In the event the Closing of the
purchase and sale transaction provided for herein does not occur as herein
provided by reason of any default of Seller, Purchaser may, as Purchaser's sole
and exclusive remedy, elect by notice to Seller within thirty (30) Business Days
following the scheduled Closing Date, either of the following: (a) terminate
this Agreement, in which event Purchaser will receive from the Title Company the
Earnest Money Deposit (and the Independent Consideration shall be paid to
Seller) whereupon Seller and Purchaser will have no further rights or
obligations under this Agreement, except with respect to the Termination
Surviving Obligations; or (b) seek to enforce specific performance of the
Agreement, and in either event, Purchaser hereby waives all other remedies,
including without limitation, any claim against Seller for damages of any type
or kind including, without limitation, consequential or punitive damages.
Failure of Purchaser to make the foregoing election within the foregoing thirty
(30) Business Day period shall be deemed an election by Purchaser to terminate
this Agreement and receive from the Title Company the Earnest Money Deposit,
whereupon Seller and Purchaser will have no further rights or obligations under
this Agreement, except with respect to the Termination Surviving Obligations.
Notwithstanding the foregoing, nothing contained in this Section 13.1 will limit
Purchaser's remedies at law, in equity or as herein provided in the event of a
breach by Seller of any of the Closing Surviving Obligations after Closing or
the Termination Surviving Obligations after termination.

        SECTION 13.2    DEFAULT BY PURCHASER. IN THE EVENT THE CLOSING AND THE
CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREIN DO NOT OCCUR AS PROVIDED
HEREIN BY REASON OF ANY DEFAULT OF PURCHASER, PURCHASER AND SELLER AGREE IT
WOULD BE IMPRACTICAL AND EXTREMELY DIFFICULT TO FIX THE DAMAGES WHICH SELLER MAY
SUFFER. PURCHASER AND SELLER HEREBY AGREE THAT (i) AN AMOUNT EQUAL TO THE
EARNEST MONEY DEPOSIT, TOGETHER WITH ALL INTEREST ACCRUED THEREON, IS A
REASONABLE ESTIMATE OF THE TOTAL NET DETRIMENT SELLER WOULD SUFFER IN THE EVENT
PURCHASER DEFAULTS AND FAILS TO COMPLETE THE PURCHASE OF THE PROPERTY, AND (ii)
SUCH AMOUNT WILL BE THE FULL, AGREED AND LIQUIDATED DAMAGES FOR PURCHASER'S
DEFAULT AND FAILURE TO COMPLETE THE PURCHASE OF THE PROPERTY, AND WILL BE
SELLER'S SOLE AND EXCLUSIVE REMEDY (WHETHER AT LAW OR IN EQUITY) FOR ANY DEFAULT
OF PURCHASER RESULTING IN THE FAILURE OF CONSUMMATION OF THE CLOSING, WHEREUPON
THIS AGREEMENT WILL TERMINATE AND SELLER AND

                                       32
<PAGE>

PURCHASER WILL HAVE NO FURTHER RIGHTS OR OBLIGATIONS HEREUNDER, EXCEPT WITH
RESPECT TO THE TERMINATION SURVIVING OBLIGATIONS. NOTWITHSTANDING THE FOREGOING,
NOTHING CONTAINED IN THIS SECTION 13.2 HEREIN WILL LIMIT SELLER'S REMEDIES AT
LAW, IN EQUITY OR AS HEREIN PROVIDED IN THE EVENT OF A BREACH BY PURCHASER OF

                          ASSIGNMENT AND BINDING EFFECT

        SECTION 15.1    ASSIGNMENT; BINDING EFFECT. Purchaser will not have the
right to assign this Agreement without Seller's prior written consent.
Notwithstanding the foregoing, Seller may assign its rights under this Agreement
to an Affiliate and, subject to Section 16.1(d), Purchaser may assign its rights
under this Agreement to a Permitted Purchaser Assignee (as hereinafter defined)
without the consent of the non-assigning party, provided that any such
assignment does not relieve the assigning party of its obligations hereunder.
This Agreement will be binding upon and, subject to Section 16.1(d), inure to
the benefit of Seller and Purchaser and their respective successors and
permitted assigns, and no other party will be conferred any rights by virtue of
this Agreement or be entitled to enforce any of the provisions hereof. Whenever
a reference is made in this Agreement to Seller or Purchaser, such reference
will include the successors and permitted assigns of such party under this
Agreement. For purposes of this Section 15.1, the term "PERMITTED PURCHASER
ASSIGNEE" shall mean: (a) an Affiliate of Purchaser; (b) any fund or entity
sponsored by Purchaser; or (c) any entity that retains Purchaser or a company
affiliated with Purchaser to manage the Property. Each such Permitted Purchaser
Assignee, as part of such assignment and assumption, shall expressly acknowledge
and agree to

                                       34
<PAGE>

the terms of this Agreement, including, without limitation, Sections 5.5, 5.6
and 5.7 and this Article XVI. Moreover, upon the assignment of this Agreement to
a Permitted Purchaser Assignee, Purchaser shall deliver to Seller either (i) a
certificate executed by such Permitted Purchaser Assignee making the
representations and warranties set forth in Section 8.2 hereof (with the
representation set forth in Section 8.2(a) modified as appropriate to conform to
the identity of the Permitted Purchaser Assignee); or (ii) a certificate
executed by Purchaser certifying that such Permitted Purchaser Assignee is in
compliance with the representations and warranties set forth in Section 8.2
hereof (with the representation set forth in Section 8.2(a) modified as
appropriate to conform to the identity of the Permitted Purchaser Assignee).

                                   ARTICLE XVI
              PROCEDURE FOR INDEMNIFICATION AND LIMITED SURVIVAL OF
                   REPRESENTATIONS, WARRANTIES AND COVENANTS

        SECTION 16.1    SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.

                (a)     Notwithstanding anything to the contrary contained in
this Agreement, (1) the representations and warranties of Seller set forth in
Section 8.1 and Seller's liability under Section 8.1, and (2) the covenants in
Section 3.2(b) and Seller's liability under Section 3.2(b), will survive the
Closing for a period of one (1) year. Purchaser will not have any right to bring
any action against Seller as a result of (i) any untruth, inaccuracy or breach
of such representations and warranties under Section 8.1, or (ii) the failure of
Seller to perform its obligations under Section 3.2(b), unless and until the
aggregate amount of all liability and losses arising out of all such untruths,
inaccuracies, breaches and failures exceeds $50,000, and then only to the extent
of such excess. In addition, in no event will Seller's liability for all such
untruths, inaccuracies, breaches, and/or failures under Sections 3.2(b) and 8.1
(including Seller's liability for attorneys' fees and costs in connection with
such untruths, inaccuracies, breaches and/or failures) exceed, in the aggregate,
$1,000,000.

                (b)     Seller shall have no liability with respect to any of
Seller's representations, warranties and covenants herein if, prior to the
Closing, Purchaser has actual knowledge of any breach of a representation,
warranty or covenant of Seller herein, or Purchaser obtains actual knowledge
(from whatever source, including, without limitation, any tenant estoppel
certificates, as a result of Purchaser's due diligence tests, investigations and
inspections of the Property, or written disclosure by Seller or Seller's agents
and employees) that contradicts any of Seller's representations, warranties or
covenants herein, and Purchaser nevertheless consummates the transaction
contemplated by this Agreement.

                (c)     The Closing Surviving Obligations will survive Closing
without limitation unless a specified period is otherwise provided in this
Agreement. All other representations, warranties, covenants and agreements made
or undertaken by Seller under this Agreement, unless otherwise specifically
provided herein, will not survive the Closing Date but will be merged into the
Closing documents delivered at the Closing. The Termination Surviving
Obligations shall survive termination of this Agreement without limitation
unless a specified period is otherwise provided in this Agreement.

                (d)     In the case of any assignment or sale of interests in
the Property to TIC Investors (as hereinafter defined): (i) the knowledge of
Purchaser and its Affiliates shall be deemed imputed to the TIC Investors for
purposes of this Agreement, (ii) Behringer Harvard TIC Management Services LP, a
Texas limited partnership and an Affiliate of Purchaser, shall act as sole agent
for notices to be provided to Purchaser and (iii) the TIC Investors shall have
no right to make claims or give notices under this Agreement except by and
through the agent referred to in clause (ii) of the preceding sentence, and then
only in the event such claims or notices are brought on behalf of all of the TIC
Investors and the other owners of the Property. Purchaser hereby agrees to
indemnify, defend and hold Seller and its members, partners, agents, officers,
directors, employees, successors, assigns and Affiliates harmless from and
against any and all liens, claims, causes of action, damages, liabilities,
demands, suits, and obligations, together with all losses, penalties, costs and
expenses relating to any of the foregoing (including but not limited to court
costs and reasonable attorneys' and consultants' fees) brought by any of the TIC
Investors or any other party in connection with the solicitation of the TIC
Investors other than claims arising from Seller's breach of this Agreement or
Seller's breach of an express representation or warranty set forth in this
Agreement or in any of the documents to be delivered at Closing, which in either
event, must be brought by the TIC Investors, if at all, in accordance with the
terms of this Section 16.1(d).

                                  ARTICLE XVII
                                  MISCELLANEOUS

        SECTION 17.1    WAIVERS. No waiver of any breach of any covenant or
provisions contained herein will be deemed a waiver of any preceding or
succeeding breach thereof, or of any other covenant or provision contained
herein. No extension of time for performance of any obligation or act will be
deemed an extension of the time for performance of any other obligation or act.

        SECTION 17.2    RECOVERY OF CERTAIN FEES. In the event a party hereto
files any action or suit against another party hereto by reason of any breach of
any of the covenants, agreements or provisions contained in this Agreement, then
in that event the prevailing party will be entitled to have and recover of and
from the other party all attorneys' fees and costs resulting therefrom, subject,
however, in the case of Seller, to the limitations set forth in Section 16.1
above. For purposes of this Agreement, the term "attorneys' fees" or "attorneys'
fees and costs" shall mean all court costs and the fees and expenses of counsel
to the parties hereto, which may include printing, photostatting, duplicating
and other expenses, air freight charges, and fees billed for law clerks,
paralegals and other persons not admitted to the bar but performing services
under the supervision of an attorney, and the costs and fees incurred in
connection with the enforcement or collection of any judgment obtained in any
such proceeding. The provisions of this Section 17.2 shall survive the entry of
any judgment, and shall not merge, or be deemed to have merged, into any
judgment.

        SECTION 17.3    TIME OF ESSENCE. Seller and Purchaser hereby acknowledge
and agree that time is strictly of the essence with respect to each and every
term, condition, obligation and provision hereof.

                                       36
<PAGE>

        SECTION 17.4    CONSTRUCTION. Headings at the beginning of each article
and section are solely for the convenience of the parties and are not a part of
this Agreement. Whenever required by the context of this Agreement, the singular
will include the plural and the masculine will include the feminine and vice
versa. This Agreement will not be construed as if it had been prepared by one of
the parties, but rather as if both parties had prepared the same. All exhibits
and schedules referred to in this Agreement are attached and incorporated by
this reference, and any capitalized term used in any exhibit or schedule which
is not defined in such exhibit or schedule will have the meaning attributable to
such term in the body of this Agreement. In the event the date on which
Purchaser or Seller is required to take any action under the terms of this
Agreement is not a Business Day, the action will be taken on the next succeeding
Business Day.

        SECTION 17.5    COUNTERPARTS. To facilitate execution of this Agreement,
this Agreement may be executed in multiple counterparts, each of which, when
assembled to include an original or faxed signature for each party contemplated
to sign this Agreement, will constitute a complete and fully executed agreement.
All such fully executed original or faxed counterparts will collectively
constitute a single agreement.

        SECTION 17.6    SEVERABILITY. If any term or other provision of this
Agreement is invalid, illegal, or incapable of being enforced by any rule of law
or public policy, all of the other conditions and provisions of this Agreement
will nevertheless remain in full force and effect, so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
adverse manner to either party. Upon such determination that any term or other
provision is invalid, illegal, or incapable of being enforced, the parties
hereto will negotiate in good faith to modify this Agreement so as to reflect
the original intent of the parties as closely as possible in an acceptable
manner to the end that the transactions contemplated hereby are fulfilled to the
extent possible.

        SECTION 17.7    ENTIRE AGREEMENT. This Agreement is the final expression
of, and contains the entire agreement between, the parties with respect to the
subject matter hereof, and supersedes all prior understandings with respect
thereto. This Agreement may not be modified, changed, supplemented or
terminated, nor may any obligations hereunder be waived, except by written
instrument, signed by the party to be charged or by its agent duly authorized in
writing, or as otherwise expressly permitted herein.

        SECTION 17.8    GOVERNING LAW. THIS AGREEMENT WILL BE CONSTRUED,
PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF GEORGIA.

        SECTION 17.9    NO RECORDING. The parties hereto agree that neither this
Agreement nor any affidavit concerning it will be recorded.

        SECTION 17.10   FURTHER ACTIONS. The parties agree to execute such
instructions to the Title Company and such other instruments and to do such
further acts as may be reasonably necessary to carry out the provisions of this
Agreement.

                                       37
<PAGE>

        SECTION 17.11   NO OTHER INDUCEMENTS. The making, execution and delivery
of this Agreement by the parties hereto has been induced by no representations,
statements, warranties or agreements other than those expressly set forth
herein.

        SECTION 17.12   EXHIBITS. EXHIBITS A through K, inclusive, are
incorporated herein by reference.

        SECTION 17.13   NO PARTNERSHIP. Notwithstanding anything to the contrary
contained herein, this Agreement shall not be deemed or construed to make the
parties hereto partners or joint venturers, it being the intention of the
parties to merely create the relationship of Seller and Purchaser with respect
to the Property to be conveyed as contemplated hereby.

        SECTION 17.14   LIMITATIONS ON BENEFITS. It is the explicit intention of
Purchaser and Seller that no person or entity other than Purchaser and Seller
and their permitted successors and assigns is or shall be entitled to bring any
action to enforce any provision of this Agreement against any of the parties
hereto, and the covenants, undertakings and agreements set forth in this
Agreement shall be solely for the benefit of, and shall be enforceable only by,
Purchaser and Seller or their respective successors and assigns as permitted
hereunder. Nothing contained in this Agreement shall under any circumstances
whatsoever be deemed or construed, or be interpreted, as making any third party
(including, without limitation, Broker or any Tenant) a beneficiary of any term
or provision of this Agreement or any instrument or document delivered pursuant
hereto, and Purchaser and Seller expressly reject any such intent, construction
or interpretation of this Agreement.

        SECTION 17.15   EXCULPATION. In no event whatsoever shall recourse be
had or liability asserted against any of Seller's partners, members,
shareholders, employees, agents, directors, officers or other owners of Seller
or their respective constituent partners. Seller's direct and indirect
shareholders, partners, members, beneficiaries and owners and their respective
trustees, officers, directors, employees, agents and security holders, assume no
personal liability for any obligations entered into on behalf of Seller under
this Agreement and the Closing documents.

        SECTION 17.16   TIC INVESTORS. Purchaser has advised Seller that, after
the expiration of the Inspection Period, Purchaser may solicit investments in
the Property from investors that will acquire undivided interests in the
Property and become tenants-in-common therein ("TIC INVESTORS"). Notwithstanding
anything contained in this Agreement to the contrary, Seller and Purchaser agree
as follows: (a) after the expiration of the Inspection Period, Purchaser shall
have the right to distribute information about the Property and this Agreement
to brokers who may facilitate the sale of such tenant in common interests and to
potential TIC Investors and their advisors; (b) subject to Section 16.1(d),
Purchaser shall have the right to assign its rights under this Agreement to TIC
Investors that invest in the Property and/or cause Seller to convey the Property
directly to such TIC Investors; and (c) after the expiration of the Inspection
Period, Purchaser may undertake other activities to accommodate the sale of
tenant in common interests and substitute TIC Investors for all or a portion of
the Purchaser's interests hereunder or in the Property. Purchaser acknowledges
and agrees that in so soliciting the TIC Investors, Purchaser is not acting as
Seller's agent and is not authorized to make representations or warranties on
behalf of Seller.

                                       38

        IN WITNESS WHEREOF, Seller and Purchaser have respectively executed this
Agreement to be effective as of the date first above written.
