                           TENANTS IN COMMON AGREEMENT

        This TENANTS IN COMMON AGREEMENT ("Agreement") is made and effective as
of the date of recordation hereof (the "Effective Date"), by and between
Behringer Harvard Enclave S LP, a Texas limited partnership ("Behringer") and
Behringer Harvard Enclave H LP, a Texas limited partnership (the "Company")
(each of Behringer and the Company shall sometimes individually be referred to
as "Tenant in Common" and collectively as "Tenants in Common"), with reference
to the facts set forth below.

                                    RECITALS

        A.      The Tenants in Common will acquire the percentage undivided
interests set forth on Exhibit "A" in certain real property and improvements, as
more particularly described in Exhibit "B" attached hereto and incorporated
herein (the "Project").

        B.      The Tenants in Common desire to enter into this Agreement to
provide for the orderly administration of their rights and responsibilities as
to each other and as to others and to delegate authority and responsibility for
the intended further operation and management of the Project.

        NOW, THEREFORE, in consideration of the mutual covenants and conditions
contained in this Agreement and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
set forth below.

        1.      NATURE OF RELATIONSHIP BETWEEN CO-TENANTS. The Tenants in Common
shall each hold their respective interests in the Project as tenants-in-common.
The Tenants in Common do not intend by this Agreement to create a partnership or
a joint venture, but merely to set forth the terms and conditions upon which
each of them shall hold their respective interests in the Project. Neither do
the Tenants in Common wish to create a partnership or joint venture with the
Property Manager (as defined below). Each Tenant in Common hereby elects to be
excluded from the provisions of Subchapter K of Chapter 1 of the Internal
Revenue Code of 1986, as amended (the "Code"), with respect to the joint
ownership of the Project. The exclusion elected by the Tenants in Common
hereunder shall commence with the execution of this Agreement and shall be
equally applicable to all assignees of a Tenant in Common upon such assignment.
Each Tenant in Common hereby covenants and agrees that each Tenant in Common
shall report on such Tenant in Common's respective federal and state income tax
returns such Tenant in Common's respective share of items of income, gain/loss,
deduction and credits that result from holding the Project in a manner
consistent with (i) the treatment of the co-tenancy as a co-ownership of real
property (and not a partnership) for Federal and state income tax purposes and
(ii) the exclusion of the Tenants in Common from Subchapter K of Chapter 1 of
the Code, commencing with the first taxable year of such Tenant in Common that
includes the Effective Date or, for assignees of a Tenant in Common, the date of
such assignment. No Tenant in Common shall notify the Commissioner of Internal
Revenue that such Tenant in Common desires that Subchapter K of the Code apply
to the Tenants in Common and each

<PAGE>

Tenant in Common hereby agrees to indemnify, protect, defend and hold the other
Tenants in Common free and harmless from all costs, liabilities, tax
consequences and expenses, including, without limitation, attorneys' fees, which
may result from any Tenant in Common so notifying the Commissioner in violation
of this Agreement or otherwise taking a contrary position on any tax return. The
Tenants in Common shall not file a partnership or corporate tax return, conduct
business under a common name, execute an agreement identifying any or all of the
Tenants in Common as partners, shareholders, or members of a business entity, or
otherwise hold themselves out as a partnership or other form of business entity.
Except as expressly provided herein, no Tenant in Common is authorized to act as
agent for, to act on behalf of, or to do any act that will bind any other Tenant
in Common or to incur any obligations with respect to the Project.

        2.      MANAGEMENT.

                2.1     Concurrently with the acquisition of the Project, the
Tenants in Common will enter into a Property and Asset Management Agreement (the
"Management Agreement") with Behringer Harvard TIC Management Services LP, a
Texas limited partnership ("Property Manager"). Pursuant to the Management
Agreement, the Property Manager shall be the sole and exclusive manager of the
Project, interface with the owner and holder of any first lien deed of trust
encumbering the Project during the term of the Management Agreement and act as
the agent of the Tenants in Common with respect to the management, operation,
maintenance and leasing of the Project during the term of the Management
Agreement. A copy of the Management Agreement is attached hereto as Exhibit "C"
and the terms, covenants and conditions of the Management Agreement are
incorporated herein as if set forth in full. Neither (a) the death, retirement,
removal, withdrawal, termination or resignation of the Property Manager, (b) any
assignment for the benefit of creditors by or the adjudication of bankruptcy or
incompetency of the Property Manager nor (c) the termination of the Management
Agreement shall cause the termination of this Agreement and this Agreement shall
remain in full force and effect notwithstanding any such events.

                2.2     UNANIMOUS CONSENT OF THE TENANTS IN COMMON. The consent
of all of the Tenants in Common shall be required with respect to any sale,
exchange, lease or release of all or a portion of the Project, any loans or
modifications of any loans secured by the Project, the approval of any property
management agreement or any extension, renewal or modification thereof. Whenever
in this Agreement the consent or approval of the Tenants in Common is required
or otherwise requested, with respect to any (i) sale or exchange of all or a
portion of the Project or (ii) loan or modification of any loan secured by the
Project, the Tenants in Common shall have fifteen (15) days after the date the
request for such consent or approval is received pursuant to Section 10.8 to
approve or disapprove of the matter. Whenever in this Agreement the consent or
approval of the Tenants in Common is required or otherwise requested, with
respect to any modification or renewal of the any property management agreement,
the Tenants in Common shall have thirty (30) days after the date the request for
consent or approval is received pursuant to Section 10.8 to the Tenants in
Common for their approval or disapproval of the matter. Whenever in this
Agreement the consent or approval of the Tenants in Common is required or
otherwise requested, with respect to any lease or release of all or a portion of
the Project, the Tenants in Common shall have five (5) days after the date the
request for consent or approval is received pursuant to Section 10.8 to the
Tenants in Common for their approval or disapproval of the matter. The Tenants
in Common agree to use their best efforts to respond to any request for consent
or approval. If a Tenant in Common does not disapprove of such matter within the
specified response period described above, the Tenant in Common shall be deemed
to have approved the matter. By execution hereof, the Tenants in Common confirm
their approval of the Property Management Agreement and that certain loan made
(or to be made immediately after the execution of this Agreement) by State Farm
Life Insurance Company (together with its successors and/or assigns, the
"Lender") secured by, among other things, a mortgage or deed of trust ("Deed of
Trust") on the Project (the "State Farm Loan").

<PAGE>

                2.3     MAJORITY CONSENT OF THE TENANTS IN COMMON. Whenever the
approval or consent of the Tenants in Common is required with respect to any
items, other than those set forth in Section 2.2, the approval or consent of the
Tenants in Common holding more than 50% of the percentage interest in the
Project shall be required to approve such action. The Tenants in Common agree to
use their best efforts to respond to any request for consent or approval. If a
Tenant in Common does not disapprove of such matter within the specified
response period described above, the Tenant in Common shall be deemed to have
approved the matter.

        3.      INCOME AND LIABILITIES. Except as otherwise provided herein and
in the Management Agreement, all benefits and obligations of the ownership of
the Project, including, without limitation, income, revenue, operating expenses,
proceeds from sale or refinance or condemnation awards shall be shared by the
Tenants in Common in proportion to their respective undivided interests in the
Project. Notwithstanding the foregoing, (a) each Tenant in Common shall be
responsible for all real estate and personal property taxes, general and special
real property assessments and other like charges (collectively "Taxes")
attributable to its undivided interest in the Project, (b) fees under the
Management Agreement shall be paid by each of the Tenants in Common as provided
in the Management Agreement and (c) expenses or other costs that are not applied
to the Tenants in Common pro rata based on their interests in the Project shall
be separately charged to each Tenant in Common. The Tenants in Common shall
receive, within 3 months of receipt by the Property Manager, all cash from
operations of the Project after payment of expenses and debt service, in
proportion to their respective undivided interests in the Project, except for
such amounts as may be determined by the Property Manager pursuant to the
Management Agreement to be retained for reserves or improvements

        4.      CO-TENANT'S OBLIGATIONS. The Tenants in Common each agree to
perform such acts as may be reasonably necessary to carry out the terms and
conditions of this Agreement, including, without limitation:

                4.1     DOCUMENTS. The Tenants in Common shall execute any and
all documents required in connection with a sale or refinancing of the Project
in accordance with Section 5 and such additional documents as may be required
under this Agreement or may be reasonably required to effect the intent of the
Tenants in Common with respect to the Project or any loans encumbering the
Project.

                4.2     ADDITIONAL FUNDS. Each Tenant in Common will be
responsible for a pro rata share (based on its undivided interest or as
otherwise provided with respect to the fees under the Management Agreement, or
other items specifically applicable to individual Tenants in Common) of any
future cash needed in connection with the ownership, operation, management and
maintenance of the Project as determined by the Property Manager pursuant to the
Management Agreement. Without limiting the foregoing, each Tenant in Common
agrees that if any loan for the Project provides for recourse liability to the
Company or any affiliate and non-recourse liability to one or more of the other
Tenants in Common, and if the Company or any affiliate pays more than its pro
rata share of the liability related to the loan (as compared to its ownership
interest) as a result of such recourse liability ("Excess Payment"), the Tenants
in Common agree to reimburse the Company or any affiliate for the Tenants in
Common's pro rata share of such Excess Payment; provided, however, that the
Property Manager has agreed to indemnify the Tenants in Common in Section 13.9.2
of the Management Agreement to the extent a Tenant in Common becomes liable to
the lender as a result of certain actions of the Property Manager. In addition,
each Tenant in Common shall be liable for, and indemnify and hold harmless, the
other Tenants in Common and their affiliates as a result of any action or
inaction by such Tenant in Common that causes any recourse liability or damages
to the Tenants in Common or their affiliates or the Project with respect to any
loan. To the extent any Tenant in Common fails to advance any funds pursuant to
this Section within fifteen (15) days after the Property Manager or the Company
delivers notice that such additional funds are required, any other Tenant(s) in
Common may pay such amount. The nonpaying

                                       3

<PAGE>

Tenant in Common shall reimburse the paying Tenant(s) in Common within 30 days
the amount of any such payments plus interest thereon at the rate of ten percent
(10%) per annum (but not more than the maximum rate allowed by law) until paid.
In the event any Tenant in Common defaults under the preceding sentence, the
Property Manager is hereby authorized to pay the Tenant(s) in Common entitled to
reimbursement and interest the amounts due out of future cash from operations or
from the sale or refinancing of the Project or other distributions pursuant to
the Management Agreement from the defaulting Tenant's in Common share of
proceeds. The remedies against a nonpaying Tenant in Common provided for herein
are in addition to any other remedies that may otherwise be available,
including, but not limited to, the right to obtain a lien against the undivided
interest in the Project of the nonpaying Tenant in Common to the extent allowed
by law. Notwithstanding the preceding provisions, however, it is expressly
understood and agreed that all such rights to, or to obtain, reimbursement are
subject and subordinate in all respects to the rights of any lender.

        5.      SALE OR ENCUMBRANCE OF PROJECT.

                5.1     SALE. In accordance with the Management Agreement, the
Property Manager shall be entitled to seek and negotiate the terms of (a)
permanent and other financing for the Project, including loans secured by the
Project, (b) the sale of the Project (or portions thereof) to third-party
purchasers (a "Sale") and (c) any lease of all or any portion of the Project.
All of the items described in (a), (b) and (c) shall require the unanimous
approval of the Tenants in Common, which approval shall be as set forth in
Section 2.2. Any such written request of the Property Manager shall be
accompanied by a copy of a bona fide offer to purchase, a loan commitment letter
setting forth all the material terms of the transaction or the principal lease
terms.

                5.2     To the extent necessary, the proceeds of a Sale shall
(i) first, be, used to pay in full any loans encumbering title to the Project
(ii) second, be used to pay all outstanding costs and expenses incurred in
connection with the holding, marketing and sale of the Project and (iii) third,
any proceeds of a Sale remaining after payment of the items set forth above
shall be paid as provided in Section 3.

        6.      POSSESSION. The Tenants in Common intend to lease the Project at
all times and no Tenant in Common shall have the right to occupy or use the
Project at any time during the term of this Agreement.

        7.      TRANSFER OR ENCUMBRANCE.

                7.1     Each Tenant in Common may sell, transfer, convey,
pledge, encumber or hypothecate its interest in the Project or any part thereof
(each a "Transfer"), provided that any transferee shall take such interest
subject to this Agreement and the Management Agreement, to the extent the
Management Agreement is in effect at the time of the Transfer, and the
transferor and transferee shall execute and cause to be recorded an assignment
and assumption agreement ("Assumption Agreement") whereby (i) the transferor
assigns to the transferee all of its right, title and interest in and to this
Agreement and the Management Agreement; and (ii) the transferee assumes and
agrees to perform faithfully and to be bound by all of the terms, covenants,
conditions, provisions and agreements of this Agreement and the Management
Agreement with respect to the undivided interest to be transferred. Upon
execution and recordation of such Assumption Agreement the transferor shall be
relieved of all liability under this Agreement accruing after the date of
recordation of the Assumption Agreement and the transferee shall become a party
to this Agreement without further action by the other Tenants in Common. The
Tenants in Common acknowledge that Behringer is selling undivided interests in
the Project pursuant to the Confidential Private Placement Memorandum of Tenant
in Common Interests in Enclave on the

                                       4
<PAGE>

Lake dated March 1, 2004. Each Tenant in Common shall be responsible for
compliance with applicable securities laws with respect to any sale of its
interest in the Project.

                7.2     RIGHT OF FIRST OFFER. If a Tenant in Common (a "Selling
Tenant") desires to sell its interest in the Project, then such Selling Tenant
shall first allow the Company or its affiliates or assigns, and second the
Tenants in Common other than the Selling Tenant (each an "Offeror" and
collectively the "Offerors") to make an offer to purchase the Selling Tenant's
interest pursuant to the terms and conditions set forth in this Section 7.2. If
a Selling Tenant desires to sell its interest in the Project, such Selling
Tenant shall provide written notice (the "Notice") of its intent to sell its
interest to each Offeror. The Company or its affiliates or its assigns shall
first have the right, within fifteen (15) days after receipt of such Notice
pursuant to Section 10.8, to deliver a written offer to the Selling Tenant to
purchase the Selling Tenant's interest in the Project. If the Selling Tenant
does not accept an offer from the Company or its affiliates or it assigns within
fifteen (15) days after receipt of the Notice pursuant to Section 10.8 then the
Tenants in Common other than the Selling Tenant shall have the right within the
next fifteen (15) days after the end of the first fifteen (15) day period, to
deliver an offer to the Selling Tenant to purchase the Selling Tenants interest
in the Project for a price that is greater than the price offered by the Company
or its affiliates or assigns. If the Selling Tenant does not accept the offer
from either the Company or its affiliates or assigns or the Tenants in Common
other than the Selling Tenant, then the Selling Tenant shall be free to sell its
interest in the Project to a purchaser other than an Offeror, provided that the
sale of the Selling Tenant's interest to a purchaser (other than an Offeror) is
for a price greater than any purchase price offered by an Offeror pursuant to
this Section 7.2 and is in compliance with the terms of any loan encumbering the
Project.

                7.3     PURCHASE OPTION. The Tenants in Common agree that the
Company or any of its affiliates or their assigns shall have the right, while
this Agreement remains in effect, to purchase a Dissenting Tenant in Common's
(as defined below) interest in the Project as set forth in this Section 7.3. A
Dissenting Tenant in Common shall mean a Tenant in Common who votes against or
fails to consent to any item that requires the unanimous approval or consent of
the Tenants in Common pursuant to the terms of this Agreement when at least 50%
of the Tenants in Common have voted or provided consent for such action. In
order to execute this option, the Company or its affiliate shall provide written
notice of its election to exercise this option to the Dissenting Tenant in
Common at any time prior to 45 days after the approval period for such vote or
consent has terminated as provided in any request for such vote or consent. In
the event that the Company or its affiliates or their assigns exercise this
purchase option, all of the Dissenting Tenant in Common's right, title and
interest in its Interest shall transfer to the Company or its affiliates or
their assigns as of the date the election to exercise the purchase option is
received by the Dissenting Tenant in Common pursuant to Section 10.8, and the
Company shall own all right, title and interest to such Interest as of such
date; provided, however, that the Company or its affiliates or their assigns may
delay the transfer of the Interest for any length of time as specified in its
election to exercise the purchase option up and through the payment date and
provided, further, that the transfer, and effective date of such transfer, shall
be subject to any consent of the Lender, if required. The purchase price of the
Dissenting Tenants in Common interest shall be equal to the Fair Market Value of
the Interest (as defined in Section 8 of this Agreement) of the Dissenting
Tenant in Common. Such purchase price sale shall be paid by the Company or its
affiliates or their assigns within 30 days of the determination of the Fair
Market Value of the Project, and the obligation to pay the purchase price shall
bear interest at the short term Applicable Federal Rate from the date of
transfer through the payment date. The purchaser and seller shall begin
negotiation of the Fair Market Value of the Project within fifteen (15) days
after the date of the written notice from the Company or assignee and shall
follow the procedures set forth in Section 8. The allocation of the costs and
liabilities shall be subject to the terms set forth in Section 8.

                7.4     DEFAULTING TENANT IN COMMON. The Tenants in Common agree
that the Company or any of its affiliates or their assigns shall have the right,
while this Agreement remains in

                                       5
<PAGE>

effect, to purchase a Defaulting Tenant in Common's (as defined below) interest
in the Project as set forth in this Section 7.4. A Defaulting Tenant in Common
shall mean a Tenant in Common who is in default under any loan documents
attributable to any loan secured by the Project, the Management Agreement or
this Agreement. In order to execute this option, the Company or its affiliate
shall provide written notice of its election to exercise this option to the
Defaulting Tenant in Common during the period such Defaulting Tenant in Common
is in default or for a period of 30 days thereafter to the Company of such
default. In the event that the Company or its affiliates or their assigns
exercise this purchase option, all of the Defaulting Tenant in Common's right,
title and interest in its Interest shall transfer to the Company or its
affiliates or their assigns as of the date the election to exercise the purchase
option is received by the Defaulting Tenant in Common pursuant to Section 10.8,
and the Company shall own all right, title and interest to such Interest as of
such date; provided, however, that the Company or its affiliates or their
assigns may delay the transfer of the Interest for any length of time as
specified in its election to exercise the purchase option up and through the
payment date and provided, further, that the transfer, and effective date of
such transfer, shall be subject to any consent of the Lender, if required. The
purchase price of the Defaulting Tenants in Common interest shall be equal to
the Fair Market Value of the Interest (as defined in Section 8 of this
Agreement) of the Defaulting Tenant in Common. Such purchase price sale shall be
paid by the Company or its affiliates or their assigns within 30 days of the
determination of the Fair Market Value of the Project, and the obligation to pay
the purchase price shall bear interest at the short term Applicable Federal Rate
from the date of transfer through the payment date. The purchaser and seller
shall begin negotiation of the Fair Market Value of the Project within fifteen
(15) days after the date of the written notice from the Company or assignee and
shall follow the procedures set forth in Section 8. The allocation of the costs
and liabilities shall be subject to the terms set forth in Section 8. In the
event a Defaulting Tenant in Common's Interest is purchased pursuant to this
Section 7.4 and the Defaulting Tenant in Common is liable to Lender for Lender's
losses as a result of the Defaulting Tenant in Common's violation of a
non-recourse carve-out under the Loan documents, the Defaulting Tenant in Common
hereby authorizes the Company to withhold from the payment of the purchase price
an amount equal to such Lender losses and to pay such amounts directly to Lender
on behalf of the Defaulting Tenant in Common.

                7.5     PURCHASE OPTION BY THE COMPANY. In the event Behringer
Harvard REIT I, Inc., ("BH REIT") becomes the member of the Company, the Company
shall have the option, but not the obligation, to purchase all of the Tenants in
Common's undivided interests in the Project as set forth in this Section 7.5. In
order to execute this option, the Company shall provide written notice of its
election to exercise this option to the Tenants in Common no sooner than 3
months prior to the end of the State Farm Loan term and no later than 30 days
prior to the end of the end of the State Farm Loan. The purchase price of each
Tenant in Common's interests shall be equal to the Fair Market Value of the
Interest (as defined in Section 8 of this Agreement) of such Tenant in Common.
Such purchase price shall be paid by the Company within 30 days of the
determination of the Fair Market Value of the Project, and the obligation to pay
the purchase price shall bear interest at the short term Applicable Federal Rate
from the date of transfer through the payment date. The Company may, in its sole
and absolute discretion, offer the Tenants in Common the option to exchange
their Interest for partnership interests in the BH REIT umbrella partnership at
an amount equal to the Fair Market Value of the Interest and at then current
fair market value of the BH REIT shares. In the event the Company does not offer
an exchange of BH REIT umbrella partnership shares or in the event the Tenant in
Common declines such offer of BH REIT umbrella partnership shares, the Tenant in
Common shall receive cash in amount equal to the Fair Market Value of such
Tenant in Common's Interest. The purchaser and seller shall begin negotiation of
the Fair Market Value of the Project within fifteen (15) days after the date of
the written notice from the Company and shall follow the procedures set forth in
Section 8. The allocation of the costs and liabilities shall be subject to the
terms set forth in Section 8.

                                       6
<PAGE>

        8.      RIGHT OF PARTITION. The Tenants in Common agree that any Tenant
in Common and any of its successors-in-interests shall have the right, while
this Agreement remains in effect, to have the Project partitioned, and to file a
complaint or institute any proceeding at law or in equity to have the Project
partitioned in accordance with and to the extent provided by applicable law. The
Tenants in Common acknowledge that partition of the Project may result in a
forced sale by all of the Tenants in Common. To avoid the inequity of a forced
sale and the potential adverse effect on the investment by the Tenants in
Common, the Tenants in Common agree that, as a condition precedent to filing a
partition action, the Tenant in Common filing such action ("Seller") shall first
make a written offer ("Offer") to sell its undivided interest first to Behringer
or its affiliates or assigns and second to the other Tenants in Common at a
price equal to the Fair Market Value of the Interest (as defined below) of
Seller's undivided interest. If Behringer does not accept such Offer, then the
other Tenants in Common shall be entitled to purchase a portion of the Seller's
interest in proportion to their undivided interest in the Project. If any Tenant
in Common elects not to purchase his or her share of the Seller's interest, the
other Tenants in Common shall be entitled to purchase additional interests based
on their undivided interest in the Project; "Fair Market Value of the Interest"
shall mean the fair market value of Seller's undivided interest (determined by
multiplying the partitioning Tenant in Common's percentage interest in the
Project on the date of the Offer by the Fair Market Value of the Project reduced
by (i) liabilities secured by the Project or liabilities taken subject to, (ii)
Seller's proportionate share of any fee or other amount that would be payable to
the Property Manager or any affiliates (including any real estate commission)
under the Management Agreement upon the sale of the Project at a price equal to
the Fair Market Value of the Project and (iii) selling, prepayment or other
costs that would apply in the event the Project was sold on the date of the
Offer) as determined in accordance with the procedures set forth below,
including any unpaid advanced made pursuant to Section 4.2 on behalf of Seller.
Behringer shall have twenty (20) days after delivery of the Offer to accept the
Offer. If Behringer does not accept the offer within such twenty (20) day
period, the other Tenants in Common shall have the right within the next twenty
(20) days to accept the Offer. If Behringer or any or all of the other Tenants
in Common ("Purchaser") accept the Offer, Seller and Purchaser shall commence
negotiation of the Fair Market Value of the Project within fifteen (15) days
after the Offer is accepted. If the parties do not agree, after good faith
negotiations, within ten (10) days, then each party shall submit to the other a
proposal containing the Fair Market Value of the Project the submitting party
believes to be correct ("Proposal"). If either party fails to timely submit a
Proposal, the other party's submitted proposal shall determine the Fair Market
Value of the Project. If both parties timely submit Proposals, then the Fair
Market Value of the Project shall be determined by final and binding arbitration
in accordance with the procedures set forth below. The parties shall meet within
seven (7) days after delivery of the last Proposal and make a good faith attempt
to mutually appoint a certified MAI real estate appraiser as an arbitrator who
shall have been active full-time over the previous five (5) years in the
appraisal of comparable properties located in the county in which the Project is
located to act as the arbitrator. If the parties are unable to agree upon a
single arbitrator, then the parties each shall, within five (5) days after the
meeting, select an arbitrator that meets the foregoing qualifications. The two
(2) arbitrators so appointed shall, within fifteen (15) days after their
appointment, appoint a third arbitrator meeting the foregoing qualifications.
The determination of the arbitrator(s) shall be limited solely to the issue of
whether Seller's or Purchaser's Proposal most closely approximates the Project's
fair market value. The decision of the single arbitrator or of the arbitrator(s)
shall be made within thirty (30) days after the appointment of a single
arbitrator or the third arbitrator, as applicable. The arbitrator(s) shall have
no authority to create an independent structure of fair market value or
prescribe or change any or several of the components or the structure thereof;
the sole decision to be made shall be which of the parties' Proposals shall
determine the Fair Market Value of the Project. The decision of the single
arbitrator or majority of the three (3) arbitrators shall be binding upon the
parties. If either party fails to appoint an arbitrator within the time period
specified above, the arbitrator appointed by one of them shall reach a decision
which shall be binding upon the parties. The cost of the arbitrators shall be
paid equally by Seller and Purchaser. The arbitration shall be conducted in
Dallas County, Texas, in accordance with the Texas Arbitration Act, ss. 171.001
et. Seq. of the Texas Civil

                                       7

Practice and Remedies Code, as modified by this Agreement. The parties agree
that Federal Arbitration Act, Title 9 of the United States Code, shall not apply
to any arbitration hereunder. The parties shall have no discovery rights in
connection with the arbitration. The decision of the arbitrator(s) may be
submitted to any court of competent jurisdiction by the party designated in the
decision. The party designated in the decision shall submit to the superior
court a form of judgment incorporating the decision of the arbitrator(s), and
such judgment, when signed by a judge of the superior court, shall become final
for all purposes and shall be entered by the clerk of the court on the judgment
roll of the court. If one party refuses to arbitrate an arbitrable dispute and
the party demanding arbitration obtains a court order directing the other party
to arbitrate, the party demanding arbitration shall be entitled to all of its
reasonable attorneys' fees and costs in obtaining such order, regardless of
which party ultimately prevails in the matter. In addition, if one party refuses
arbitration and is subsequently ordered by a court to arbitrate, such party
shall also pay all of the arbitration costs and expenses. By executing this
Agreement each Tenant in Common is agreeing to have any dispute arising out of
the matters included in the arbitration of disputes provision decided by neutral
arbitration as provided by Texas law and each Tenant in Common is giving up its
rights might possess to have the dispute litigated in a court or jury trial. By
executing this Agreement you are giving up your judicial rights to discovery and
appeal. If a Tenant in Common refuses to submit to arbitration after agreeing to
this provision, the Tenant in Common may be compelled to arbitrate under the
authority of the Texas Arbitration Act, ss. 171.001 et. Seq. of the Texas Civil
Practice and Remedies Code. Each Tenant in Common's agreement to Tenant in
Common arbitration provision is voluntary. The closing of the purchase of
Seller's interest shall occur at a mutually agreeable title company where the
Project is located within 30 days from the date a Fair Market Value of the
Project is determined, whether by agreement or arbitration. Closing costs and
prorations shall be allocated as is standard practice where the Project is
located. The Purchaser shall take Seller's interest subject to the liabilities
included in the determination of Fair Market Value of the Project secured by the
Project and the Management Agreement which may include unpaid fees due to the
Property Manager. In the event a portioning Tenant in Common's Interest is
purchase pursuant to this Section 8 and the partitioning Tenant in Common is
liable to Lender for Lender's losses as a result of the portioning Tenant in
Common's violation of a non-recourse carve-out under the Loan documents, the
partitioning Tenant in Common hereby authorizes the Company to withhold from the
payment of the purchase price an amount equal to such Lender losses and to pay
such amounts directly to Lender on behalf of the portioning Tenant in Common.

        9.      BANKRUPTCY OPTION.

                9.1     OPTION. If, during the term of this Agreement, a Tenant
in Common is Bankrupt, Behringer and/or an affiliate or assignee shall have the
right, to be exercised by written notice ("Bankruptcy Call Notice") to the
Bankrupt Tenant in Common, to purchase all of the Bankrupt Tenant in Common's
interest in the Project. Upon receipt of the Bankruptcy Call Notice, the
Bankrupt Tenant in Common shall be obligated to provide Behringer and/or its
affiliate or in the event that Behringer and/or an affiliate does not elect to
exercise the option within 20 days of the receipt of the Bankruptcy Call Notice,

the Fair Market Value of the Project. The allocation of the costs and
liabilities shall be subject to the terms set forth in Section 8. In the event a
bankrupt Tenant in Common's Interest is purchased pursuant to this Section 9.1

result of the bankrupt Tenant in Common's violation of a non-recourse carve-out
under the Loan documents, the bankrupt Tenant in Common hereby authorizes the
Company to withhold from the payment of the purchase price funds in an amount
equal to such Lender losses and to pay such amounts directly to Lender on behalf

                9.3     RIGHT OF FIRST REFUSAL. If, under federal bankruptcy
law, similar debtor relief laws, or other laws affecting the Project, the option
to purchase granted under this Section 9 is voided or declared unenforceable,
Behringer and/or an affiliate shall have a right of first refusal to buy any
interest in the Project of a Bankrupt Tenant in Common in the event of any
proposed transfer by a trustee, receiver, conservator, liquidator, guardian, or
other transferee. Such right of first refusal shall provide that Behringer
and/or its affiliate may purchase the Bankrupt Tenant in Common's interest in
the Project at the same price and on the same terms as such Project is proposed
to be sold by such trustee, receiver, conservator, liquidator, guardian or other
transferee.
