                               REPAYMENT GUARANTY


        THIS REPAYMENT GUARANTY (as the same may from time to time hereafter be
modified, supplemented or amended, the "GUARANTY") is made as of October 4,
2004, by BEHRINGER HARVARD SHORT-TERM OPPORTUNITY FUND I LP, having an address

                                    RECITALS:

A.      Lender has agreed to make a loan (the "LOAN") in the original principal
sum of SIX MILLION and No/100 Dollars (U.S. $6,000,000.00) to Behringer Harvard
1221 Coit LP, a Texas limited partnership ("BORROWER"); and

B.      The Loan is evidenced by Borrower's secured promissory note of even date
herewith made payable and delivered to Lender (as the same may from time to time
hereafter be modified, amended, supplemented, extended or consolidated, and any
note(s) issued in exchange therefore or replacement thereof, the "NOTE") and
further evidenced and secured by a mortgage executed by Borrower of even date
herewith (it being agreed that "MORTGAGE" as hereinafter used shall be construed
to mean "mortgage" or "deed of trust" or "trust deed" or "deed to secure debt"
as the context so requires, as the same may from time to time hereafter be
modified, amended, supplemented or extended) on the Premises more particularly
described in said Mortgage; and

C.      In connection with the Loan, the Borrower has also entered into that
certain Loan Agreement of even date herewith by and between Lender and Borrower
(as the same may from time to time hereafter be modified, amended, supplemented
or extended, the "LOAN AGREEMENT"); and

D.      It is a condition of Lender's agreement to make the Loan that Guarantor
be unconditionally liable for and personally guarantee the payment and
performance of the Indebtedness represented by the Note and the performance of
any and all other liabilities and obligations of the Borrower under the Loan
Documents upon the terms and conditions as are hereinafter set forth; and

E.      Guarantor is financially interested in Borrower and is materially
benefited by the consummation of the Loan and has agreed to unconditionally and
personally guarantee the payment and performance of the Indebtedness represented
by the Note and the performance of any and all other liabilities and obligations
of Borrower under the Loan Documents upon the terms and conditions as are
hereinafter set forth.

        NOW, THEREFORE, in order to induce Lender to make the Loan to Borrower,
Guarantor, intending to be legally bound, hereby makes the following
representations and warranties to Lender and hereby covenants and agrees with
Lender as follows:

1.      FULL GUARANTY. Guarantor hereby unconditionally, absolutely and
irrevocably guarantees and promises to pay to Lender or order, on demand, in
lawful money of the United States of America, in immediately available funds,
the Loan when due, whether by acceleration or otherwise, together with all
interest thereon, any other sums that become due and owing to Lender under the
Loan Documents, including, without limitation, late charges, premiums for
prepayment, expenditures by Lender to preserve and protect the collateral for
repayment of the Note, amounts that would become due but for the effect of any
bankruptcy proceedings or other insolvency proceedings and all attorneys' fees,
costs, and expenses of collection incurred by Lender in enforcing its rights and

                                       1
<PAGE>

remedies under the Loan Documents, and together with the full and complete
discharge and performance of each and every other term, covenant, obligation,
and warranty contained in the Loan Documents.

2.      REMEDIES. If Guarantor fails to promptly perform its obligations under
this Guaranty, Lender may from time to time, and without first requiring
performance by Borrower or exhausting any or all security for the Loan, bring
any action at law or in equity or both to compel Guarantor to perform its
obligations hereunder, and to collect in any such action compensation for all
loss, cost, damage, injury and expense sustained or incurred by Lender as a
direct or indirect consequence of the failure of Guarantor to perform its
obligations, together with interest thereon at the rate of interest applicable
to the principal balance of the Note. Any amounts due under this SECTION 2 shall
be in addition to the amounts due under SECTION 1 of this Guaranty.
Notwithstanding anything contained herein to the contrary, any liability of
Guarantor under this Guaranty shall be satisfied solely out of the properties
and assets of Guarantor that may exist from time to time and Lender specifically
agrees that there shall be no recourse under this Guaranty to the general or
limited partners of Guarantor, or their respective properties and assets, for
the satisfaction of any liability of Guarantor hereunder.

3.      RIGHTS OF LENDER. Guarantor authorizes Lender, without giving notice to
Guarantor or obtaining Guarantor's consent and without affecting the liability
of Guarantor, from time to time to: (a) renew or extend all or any portion of
Borrower's obligations under the Note, the Loan Agreement or any of the other
Loan Documents; (b) declare all sums owing to Lender under the Note, the Loan
Agreement and the other Loan Documents due and payable upon the occurrence of an
Event of Default under the Loan Documents; (c) make changes in the dates
specified for payments of any sums payable in periodic installments under the
Note, the Loan Agreement or any of the other Loan Documents; (d) otherwise
modify, amend, supplement or replace from time to time the terms of any of the
Loan Documents; (e) take and hold security for the performance of Borrower's
obligations under the Note, the Loan Agreement or the other Loan Documents and
exchange, enforce, waive and release any such security; (f) apply such security
and direct the order or manner of sale thereof as Lender in its sole discretion
may determine; (g) release, substitute or add any one or more endorsers of the
Note or guarantors of Borrower's obligations under the Note, the Loan Agreement
or the other Loan Documents; (h) apply payments received by Lender from Borrower
to any obligations of Borrower to Lender, in such order as Lender shall
determine in its sole discretion, whether or not any such obligations are
covered by this Guaranty; and (i) assign this Guaranty in whole or in part.

4.      WAIVERS. Guarantor waives: (a) any defense based upon any legal
disability or other defense of Borrower, any other guarantor or other Person, or
by reason of the cessation or limitation of the liability of Borrower from any
cause other than full payment of all sums payable under the Note, the Loan
Agreement or any of the other Loan Documents; (b) any defense based upon any
lack of authority of the officers, directors, partners, members, managers or
agents acting or purporting to act on behalf of Borrower or any principal of
Borrower or any defect in the formation of Borrower or any principal of
Borrower; (c) any defense based upon the application by Borrower of the proceeds
of the Loan for purposes other than the purposes represented by Borrower to
Lender or intended or understood by Lender or Guarantor; (d) all rights and
defenses arising out of an election of remedies by Lender, even though that
election of remedies, such as a nonjudicial foreclosure with respect to security
for a guaranteed obligation, has destroyed Guarantor's rights of subrogation and
reimbursement against Borrower; (e) any defense based upon Lender's failure to
disclose to Guarantor any information concerning Borrower's financial condition
or any other circumstances bearing on Borrower's ability to pay all sums payable
under the Note, the Loan Agreement or any of the other Loan Documents; (f) any
defense based upon any statute or rule of law which provides that the obligation
of a surety must be neither larger in amount nor in any other respects more
burdensome than that of a principal; (g) any defense based upon Lender's
election, in any proceeding instituted under the Bankruptcy Code, of the
application of Section 1111(b)(2) of the Bankruptcy Code or any successor
statute; (h) any defense based upon any borrowing or any grant of a security
interest under Section 364 of the Bankruptcy Code; (i) presentment, demand,
protest and notice of any kind; and (j) the benefit of any statute of
limitations affecting the liability of Guarantor hereunder or the enforcement
hereof. In addition, Guarantor waives all rights and defenses that Guarantor may
have because Borrower's debt is secured by real property, including, without
limitation, those contained in Sections 51.004 and 51.005 of the Texas Property
Code. This means, among other things: (A) Lender may collect from Guarantor
without first foreclosing on any real or personal property collateral pledged by
Borrower; and (B) if Lender forecloses on any real property collateral pledged
by Borrower, then (i) the amount of the debt may be reduced only by the price
for which that collateral is sold at the foreclosure sale, even if the
collateral is worth more than the sale price; and (ii) Lender may collect from
Guarantor even if Lender, by foreclosing on the real property collateral, has
destroyed any right Guarantor may have to collect from Borrower.

                                        2
<PAGE>

The foregoing sentence is an unconditional and irrevocable waiver of any rights
and defenses Guarantor may have because Borrower's debt is secured by real
property. Finally, Guarantor agrees that the payment of all sums payable under
the Note, the Loan Agreement or any of the other Loan Documents or any part
thereof or other act which tolls any statute of limitations applicable to the
Note, the Loan Agreement or the other Loan Documents shall similarly operate to
toll the statute of limitations applicable to Guarantor's liability hereunder.

5.      REPRESENTATIONS, WARRANTIES AND COVENANTS. Guarantor represents,
warrants and acknowledges that: (a) Lender would not make the Loan but for this
Guaranty; (b) there are no conditions precedent to the effectiveness of this
Guaranty; (c) Guarantor has established adequate means of obtaining from sources
other than Lender, on a continuing basis, financial and other information

to Guarantor as to any such matters; (d) the most recent financial statements of
Guarantor previously delivered to Lender are true and correct in all respects,

Guarantor since the respective dates thereof; (e) Guarantor has received copies

Lender; (g) Guarantor and Borrower are separate and distinct entities with no
identity of interest with respect to any Indebtedness which may become owed or

authorized by all requisite action; (iii) have received all necessary approvals

judgment of any court or governmental authority, the articles of incorporation,
by-laws, partnership, operating or trust agreement, or other governing
instrument of Guarantor, or any indenture, agreement or other instrument to
which Guarantor is a party or by which Guarantor or any of Guarantor's assets is
or may be bound or affected; (v) does not and will not result in the creation or
imposition of any lien, charge or encumbrance whatsoever upon any of Guarantor's

information, including, without limitation, annual financial

                                       5
<PAGE>

statements, cash flow projections and quarterly operating statements, requested
by Lender. Additionally, Guarantor shall delivery to Lender, as soon as
available, but in no event later than sixty (60) days after each Quarterly
Financial Covenant Test Date, a current, unaudited financial statement
(including, without limitation, an income and expense statement, balance sheet
and cash flow statement) signed by Guarantor's Chief Financial Officer. Within
sixty (60) days of Lender's request, Guarantor shall also deliver to Lender such
other financial information as Lender may specify. Except as set forth herein or
otherwise agreed to by Lender, all such financial information shall be prepared
on a GAAP Basis consistently applied.

        (e)     QUARTERLY FINANCIAL COVENANT COMPLIANCE CERTIFICATES. On or
before sixty (60) days following each Quarterly Financial Covenant Test Date,
Guarantor shall deliver to Lender a Financial Covenant Compliance Certificate in
form attached hereto as EXHIBIT A ("QUARTERLY COMPLIANCE CERTIFICATE"),
certified by an officer of Guarantor, and an unqualified, unaudited financial
statement of Guarantor covering the preceding twelve (12) month period. Upon
request of Lender, Borrower shall provide any and all financial information and
statements and other documents or items to support or evidence the
certifications contained in each Quarterly Compliance Certificate.

7.      SUBORDINATION. Guarantor subordinates all present and future
indebtedness owing by Borrower to Guarantor to the Indebtedness at any time
owing by Borrower to Lender under the Note, the Loan Agreement and the other
Loan Documents; PROVIDED, HOWEVER, so long as no Event of Default has occurred
and is continuing, Guarantor shall be entitled to receive partnership
distributions from Borrower to the extent attributable solely to Guarantor's
limited partnership interest in Borrower. Guarantor agrees that as long as this
Guaranty is in effect, Guarantor will not take any action or initiate any
proceedings, judicial or otherwise, to enforce Guarantor's rights or remedies
with respect to any such indebtedness, including, without limitation, any action
to enforce remedies with respect to any defaults under such indebtedness or to
any collateral securing such indebtedness or to obtain any judgment or
prejudgment remedy against Borrower or any such collateral. Guarantor also
agrees that it shall not commence or join with any other creditor or creditors
of Borrower in commencing any bankruptcy, reorganization or insolvency
proceedings against Borrower. Guarantor further agrees not to assign all or any
part of such indebtedness unless Lender is given prior notice and such
assignment is expressly made subject to the terms of this Guaranty. If Lender so
requests, (a) all instruments evidencing such indebtedness shall be duly
endorsed and delivered to Lender, (b) all security for such indebtedness shall
be duly assigned and delivered to Lender, (c) such indebtedness shall be
enforced, collected and held by Guarantor as trustee for Lender and shall be
paid over to Lender on account of the Loan, but without reducing or affecting in
any manner the liability of Guarantor under the other provisions of this
Guaranty; and (d) Guarantor shall execute, file and record such documents and
instruments and take such other action as Lender deems necessary or appropriate
to perfect, preserve and enforce Lender's rights in and to such indebtedness and
any security therefor. If Guarantor fails to take any such action, Lender, as
attorney-in-fact for Guarantor, is hereby authorized to do so in the name of
Guarantor. The foregoing power of attorney is coupled with an interest and
cannot be revoked.

8.      BANKRUPTCY OF BORROWER. In any bankruptcy or other proceeding in which
the filing of claims is required by law, Guarantor shall file all claims which
Guarantor may have against Borrower relating to any indebtedness of Borrower to
Guarantor and shall assign to Lender all rights of Guarantor thereunder. If
Guarantor does not file any such claim, Lender, as attorney-in-fact for
Guarantor, is hereby authorized to do so in the name of Guarantor or, in
Lender's discretion, to assign the claim to a nominee and to cause proof of
claim to be filed in the name of Lender's nominee. The foregoing power of
attorney is coupled with an interest and cannot be revoked. Lender or its
nominee shall have the right, in its reasonable discretion, to accept or reject
any plan proposed in such proceeding and to take any other action which a party
filing a claim is entitled to do. In all such cases, whether in administration,
bankruptcy or otherwise, the Person or Persons authorized to pay such claim
shall pay to Lender the amount payable on such claim and, to the full extent
necessary for that purpose, Guarantor hereby assigns to Lender all of
Guarantor's rights to any such payments or distributions; PROVIDED, HOWEVER,
Guarantor's obligations hereunder shall not be satisfied except to the extent
that Lender receives cash by reason of any such payment or distribution. If
Lender receives anything hereunder other than cash, the same shall be held as
collateral for amounts due under this Guaranty. If all or any portion of the
obligations guarantied hereunder are paid or performed, the obligations of
Guarantor hereunder shall continue and shall remain in full force and effect in
the event that all or any part of such payment or performance is avoided or
recovered directly or indirectly from Lender as a preference, fraudulent
transfer or otherwise under the Bankruptcy Code or other similar laws,
irrespective of: (a) any notice of

                                       6
<PAGE>

revocation given by Guarantor prior to such avoidance or recovery; and (b) full
payment and performance of all of the Indebtedness and obligations evidenced and
secured by the Loan Documents.

9.      DISCLOSURE OF INFORMATION; PARTICIPATIONS. Guarantor agrees that Lender
may elect, at any time, to sell, assign, participate or securitize all or any
portion of Lender's rights and obligations under the Loan Documents (any of the
foregoing, a "SECURITIZATION TRANSACTION"). Guarantor agrees that Lender may
disseminate any and all information pertaining to the Premises, Borrower, any
Interest Owner, Guarantor or any other guarantor to any relevant party in
connection with such Securitization Transaction.

10.     ADDITIONAL AND INDEPENDENT OBLIGATIONS. This is a guaranty of payment
and not of collection and the obligations of Guarantor hereunder shall be in
addition to and shall not limit or in any way affect the obligations of
Guarantor under any other existing or future guaranties unless said other
guaranties are expressly modified or revoked in writing. This Guaranty is
independent of the obligations of Borrower under the Note, the Loan Agreement,
the Mortgage and the other Loan Documents. Guarantor agrees that nothing
contained in this Guaranty shall prevent Lender from suing to collect on the
Note or from exercising concurrently or successively any rights available to it
at law and/or in equity or under any of the Loan Documents, and that the
exercise of any of the aforesaid rights shall not constitute a legal or
equitable discharge of Guarantor. Guarantor hereby authorizes and empowers
Lender to exercise, in its sole discretion, any rights and remedies, or any
combination thereof, which may then be available, since it is the intent and
purpose of Guarantor that the obligations hereunder shall be absolute,
independent and unconditional under any and all circumstances. Lender may bring
a separate action to enforce the provisions hereof against Guarantor without
taking action against Borrower or any other Person or joining Borrower or any
other Person as a party to such action.

11.     MISCELLANEOUS.

        11.1    GUARANTY NOT SECURED BY LOAN DOCUMENTS. Notwithstanding anything
contained herein or in the other Loan Documents to the contrary, this Guaranty
and all obligations of Guarantor arising under it shall not be secured in any
manner whatsoever, including by the Mortgage or by any lien encumbering the
Premises.

        11.2    ATTORNEYS' FEES; ENFORCEMENT. If any attorney is engaged by
Lender to enforce or defend any provision of this Guaranty, or any of the other
Loan Documents, or as a consequence of any Event of Default under the Loan
Documents, with or without the filing of any legal action or proceeding
(including any bankruptcy proceeding), Guarantor shall pay to Lender immediately
upon demand all reasonable attorneys' fees and costs incurred by Lender in
connection therewith, together with interest thereon from the date of such
demand until paid at the rate of interest applicable to the principal balance of
the Note as specified therein. Any amounts due under this SECTION 11.2 shall be
in addition to the amounts due under SECTION 1 of this Guaranty.

        11.3    RULES OF CONSTRUCTION; DEFINED TERMS. The word "Borrower" as
used herein shall include both the named Borrower and any other Person at any
time assuming or otherwise becoming primarily liable for all or any part of the
obligations of the named Borrower under the Note, the Loan Agreement and the
other Loan Documents. If this Guaranty is executed by more than one Person, the
term "Guarantor" shall include all such Persons. When the context and
construction so require, all words used in the singular herein shall be deemed
to have been used in the plural and vice versa. All headings appearing in this
Guaranty are for convenience only and shall be disregarded in construing this
Guaranty. Capitalized terms not otherwise defined herein shall have the meanings
set forth in the Loan Agreement or the other Loan Documents, as applicable.

        11.4    CREDIT REPORTS. Each Person obligated on this Guaranty hereby
authorizes Lender to order and obtain, from a credit reporting agency of
Lender's choice, a third party credit report on such Person.

        11.5    GOVERNING LAW. This Guaranty shall be governed by, and construed
in accordance with, the laws of the State where the Premises are located,
without regard to its conflict of law principles.

        11.6    CONSENT TO JURISDICTION. Guarantor irrevocably submits to the
jurisdiction of any state or federal court sitting in the State of Washington,
the State where the Premises are located, and the State in which Guarantor's
principal place of business is located over any suit, action, or proceeding
arising out of or relating to this Guaranty,

                                       7
<PAGE>

the Loan Documents or the Loan evidenced thereby and any state court sitting in
the county of the State where the Premises are located over any suit, action, or
proceeding brought by Lender to exercise any of its rights under this Guaranty
or the Loan Documents. Guarantor irrevocably waives, to the fullest extent
permitted by law, any objection that Guarantor may now or hereafter have to the
laying of venue of any such suit, action or proceeding brought in any such court
and any claim that any such suit, action or proceeding brought in any such court
has been brought in an inconvenient forum. Guarantor further consents and agrees
to service of any summons, complaint or other legal process in any such suit,
action or proceeding by registered or certified U.S. mail, postage prepaid, to
Guarantor at the address for notices described on page 1 of this Guaranty, and
consents and agrees that such service shall constitute in every respect valid
and effective service (but nothing herein shall affect the validity or
effectiveness of process served in any other manner permitted by law).

        11.7    HEIRS, SUCCESSORS AND ASSIGNS. The provisions of this Guaranty
will bind and benefit the heirs, executors, administrators, legal
representatives, nominees, successors and assigns of Guarantor and Lender.

        11.8    JOINT AND SEVERAL LIABILITY. The liability of all Persons who
are in any manner obligated hereunder shall be joint and several.

        11.9    SEVERABILITY. If any provision of this Guaranty shall be
determined by a court of competent jurisdiction to be invalid, illegal or
unenforceable, that portion shall be deemed severed from this Guaranty and the
remaining parts shall remain in full force as though the invalid, illegal or
unenforceable portion had never been part of this Guaranty.

        11.10   SURVIVAL. This Guaranty shall be deemed to be continuing in
nature and shall remain in full force and effect and shall survive the exercise
of any remedy by Lender under the Mortgage or any of the other Loan Documents,
including, without limitation, any foreclosure or deed in lieu thereof.

        11.11   ENFORCEABILITY. Guarantor hereby acknowledges that: (a) the
obligations undertaken by Guarantor in this Guaranty are complex in nature; and
(b) numerous possible defenses to the enforceability of these obligations may
presently exist and/or may arise hereafter; and (c) as part of Lender's
consideration for entering into the Loan, Lender has specifically bargained for
the waiver and relinquishment by Guarantor of all such defenses; and (d)
Guarantor has had the opportunity to seek and receive legal advice from skilled
legal counsel in the area of financial transactions of the type contemplated
herein. Given all of the above, Guarantor does hereby represent and confirm to
Lender that Guarantor is fully informed regarding, and that Guarantor does
thoroughly understand: (i) the nature of such possible defenses; and (ii) the
circumstances under which such defenses may arise; and (iii) the benefits which
such defenses might confer upon Guarantor; and (iv) the legal consequences to
Guarantor of waiving such defenses. Guarantor acknowledges that Guarantor makes
this Guaranty with the intent that this Guaranty and all of the informed waivers
herein shall each and all be fully enforceable by Lender, and that Lender is
induced to enter into the Loan in material reliance upon the presumed full
enforceability thereof.

        11.12   COUNTERPARTS. This Guaranty may be executed in counterparts,
each of which shall be deemed an original, and such counterparts when taken
together shall constitute but one agreement.
