                                SALE AND PURCHASE

        SECTION 1.1    Subject to the terms and provisions hereof, Seller agrees

        with all right, title and interest of Seller in and to any and all
        roads, easements, streets and ways bounding the Real Property, and
        rights of ingress and egress thereto; provided, however, that to the
        extent the Survey reflects a different description for the Real Property
        than that which is reflected on EXHIBIT A attached hereto, the field
        notes for the Survey (once approved as provided herein below) shall be

                (c)     All Personal Property (herein so called) owned by Seller
        with respect to the Real Property or Improvements, including without
        limitation, (i) all licenses, permits, certificates of occupancy and

        SECTION 2.1    The Purchase Price (herein so called) to be paid by

terminated prior to the expiration of the Due Diligence Period pursuant to

before Closing, terminate this Agreement and retain the initial Earnest Money.
The Title Company shall hold the Earnest Money in an interest-bearing account
reasonably satisfactory to Seller and Purchaser. All interest which accrues on
the Earnest Money shall constitute a portion of the Earnest Money and shall be

                                    ARTICLE 4

           SURVEY, TITLE COMMITMENT, TITLE DOCUMENTS AND TITLE POLICY

        SECTION 4.1    Within ten (10) days after the Effective Date, Seller
shall, at its sole cost and expense, cause to be prepared and delivered to
Purchaser a current as-built survey of the Real Property and Improvements (the
"Survey"). The Survey shall be prepared by a Registered Professional Land
Surveyor licensed in the State of Texas and shall conform to the standards for a
Category 1A, Condition II Survey according to the current Manual of Practice for
Land Surveying in Texas of the Texas Society of Surveyors. The Survey shall form
the basis for the legal description of the Property.

        SECTION 4.2    Within fifteen (15) days after the Effective Date,
Seller, at Seller's sole cost and expense, shall furnish to Purchaser a current
commitment with respect to the Real Property and Improvements (the "Title
Commitment") for the issuance of an Owner's Policy of Title Insurance to
Purchaser through Republic Title, 2626 Howell Street, 10th Floor, Dallas, Texas
75204; Attention: Pauletta Hubbard (the "Title Company"), together with legible
copies of all documents (the "Title Documents") constituting exceptions to
Seller's title as reflected in the Title Commitment, including legible copies of
the current plat, if any, filed in the map and plat records.

        SECTION 4.3    Purchaser shall have a period of ten (10) days (the
"Title and Survey Review Period") from its receipt of the last of the Survey,
the Title Commitment and the Title Documents (collectively, "Title and Survey")
to review the Title and Survey and to object in writing to Seller as to any
matters therein to which Purchaser objects (the "Objections"). If Purchaser
fails to so object prior to the expiration of the Title and Survey Review
Period, Purchaser shall be deemed to have approved and accepted Title and
Survey, and all matters shall be deemed Permitted Exceptions (herein so called).
If Purchaser notifies Seller in writing of any Objections prior to the
expiration of the Title and Survey Review Period, Seller shall then have a
period of ten (10) days after its receipt of such notice to cure the

                                       2
<PAGE>

Objections, or to notify Purchaser in writing of any Objections Seller cannot
cure (the "Cure Notice"). Any matters not included in Purchaser's Objections
shall be deemed Permitted Exceptions. Seller agrees to use its best efforts to
cure the Objections; provided, however, in no event shall Seller be obligated to
spend any money whatsoever to cure Objections, or institute litigation or other
proceedings to cure Objections, provided further, however, and notwithstanding
the foregoing, Seller will be required to satisfy any monetary liens at or
before Closing, by any means which Seller deems appropriate. Upon Purchaser's
receipt of the Cure Notice, Purchaser shall have until the expiration of the Due
Diligence Period (as hereinafter defined) to either (i) terminate this Contract,
and be entitled to the immediate return of the Initial Earnest Money which shall
be immediately delivered to Purchaser by Seller, with neither party hereto being
thereafter obligated to the other, except as to Purchaser's indemnification
liability pursuant to Section 8.1 hereof, or (ii) waive the Objections by
written notice to Seller and proceed to Closing with all uncured Objections
constituting Permitted Exceptions. If Purchaser fails to notify Seller of its
election prior to the expiration of the Due Diligence Period, Purchaser shall be
deemed to have terminated this Contract pursuant to (i) above. Notwithstanding
anything contained herein to the contrary (and except as permitted pursuant to
the terms and provisions of Article 10), Seller may not, at any time after the
Effective Date, place any new encumbrances and/or restrictions on the Property
without the prior written consent of Purchaser, except in the normal course of
the business of the hotel operated on the Property and for normal maintenance of
the Property (but only so long as any of the foregoing are cancelable effective
on or before the Closing Date). Permitted Exceptions shall include for all
purposes: (a) the standard exceptions on the current Texas standard printed form
of Owner Policy of Title Insurance and (b) taxes for the year of Closing and
subsequent years.

        SECTION 4.4    At Closing, Seller shall furnish Purchaser, at Seller's
cost and expense (excluding any additional premium for the deletion or addition
of any provision, rider, or addendum desired by Purchaser), with an Owner's
Policy of Title Insurance (the "Title Policy") issued on the standard form in
use in the State of Texas, from a title insurance underwriter reasonably
acceptable to Purchaser, insuring good and indefeasible title to the Real
Property and Improvements in the Purchaser, subject only to the Permitted
Exceptions. If Purchaser desires removal or addition of any provision, rider, or
addendum, Purchaser shall pay the additional premiums.

                                    ARTICLE 5

                        ADDITIONAL ITEMS TO BE FURNISHED
                             TO PURCHASER BY SELLER

        SECTION 5.1    Within ten (10) days after the Effective Date, Seller
shall deliver to Purchaser complete and legible copies of all records, reports,
permits, documents and information reasonably requested by Purchaser, relating
to the Property, to the extent David Humphreys (the authorized representative of
Seller) is in possession or control of such items, including, without
limitation, the following:

                (a)     Copies of all engineering, soils and inspection reports
        relating to the Real Property or Improvements;

                (b)     Copies of all environmental reports and other
        environmental information relating to the Real Property or Improvements;

                (c)     Copies of any existing insurance certificates with
        respect to the Real Property and Improvements; and

                                       3
<PAGE>

                (d)     Copies of any leases, contracts or other agreements
        relating to the Real Property or Improvements; provided, with respect to
        any residential leases, Seller shall only be required to deliver to
        Purchaser a Hotel guest list certified as being true and correct by
        David Humphreys for the residential leases in form and substance
        reasonably acceptable to Purchaser (and having attached thereto Seller's
        customary residential lease form).

Notwithstanding the foregoing, Purchaser acknowledges and agrees that David
Humphreys has previously delivered to Purchaser those items described in EXHIBIT
B attached hereto.

                                    ARTICLE 6

                   CONDEMNATION AND CASUALTY PRIOR TO CLOSING

        SECTION 6    If prior to the Closing of this transaction, all or any
substantial part of the Premises is condemned, damaged, or destroyed, Purchaser
shall have the option of either receiving an assignment of the proceeds of any
condemnation award or insurance policies up to the amount of the Purchase Price
with any remainder to Seller and proceed to closing without any reduction in the
total consideration provided herein or declare this contract terminated by
delivering written notice of termination pursuant to this paragraph to Seller
within ten (10) days of the date Seller notifies Purchaser in writing of such
condemnation, damage, or destruction. If necessary, the Closing Date will be
extended to allow for such ten (10) day period. In the event of such
termination, Purchaser shall be entitled to a refund of the Earnest Money and
any Early Termination Fee. However, notwithstanding anything to the contrary
herein, if any damage or destruction is the result of activities of Purchaser,
Purchaser's agent, or Purchaser's consultants, then Purchaser shall be obligated
to perform this Agreement as if the damage or destruction had not occurred.
Further, if the Closing fails to take place for any reason, Purchaser will be
liable to Seller for any damages or destruction to the Premises resulting from
the activities of Purchaser, Purchaser's agents, or Purchaser's consultants.
"Substantial" as used in the first sentence of this paragraph shall mean new
condemnation, damage, or destruction that did not exist prior to the Effective
Date of this Agreement and which is in an amount of $100,000.00 or more.
Purchaser acknowledges that the Premises is currently in damaged condition, and
Purchaser accepts such condition and any new condemnation, damage, or
destruction that is not substantial as defined in this paragraph.

                                    ARTICLE 7

The foregoing representations and warranties are limited to the knowledge of

        SECTION 7.2    PURCHASER ACKNOWLEDGES THAT FOR SELLER'S PURPOSES, THE
PROPERTY HAS NOT BEEN USED OR UNDER THE DIRECT CONTROL OF SELLER FOR A
CONSIDERABLE LENGTH OF TIME, AND THAT SELLER HAS LITTLE, IF ANY, KNOWLEDGE OF
THE PHYSICAL CONDITION OR ECONOMIC CHARACTERISTICS OF THE PROPERTY. SELLER
HEREBY DISCLOSES TO PURCHASER THAT THE PROPERTY IS IN DISREPAIR AND THAT
UTILITIES AND OTHER FACILITIES MAY BE LACKING OR INADEQUATE TO OPERATE ANY
BUSINESS AT THE PROPERTY. PURCHASER ACCEPTS THE PROPERTY "AS IS" IN ITS PRESENT
CONDITION AND WITH ALL DEFECTS AND, EXCEPT AS TO WARRANTIES OF TITLE AND OTHER
REPRESENTATIONS AND WARRANTIES AS SPECIFIED AND LIMITED HEREIN. SELLER MAKES NO
WARRANTY OR REPRESENTATION, EXPRESSED OR IMPLIED, OR ARISING BY OPERATION OF

AUTHORITY. SELLER MAKES NO WARRANTIES OR REPRESENTATIONS CONCERNING THE
EXISTENCE OR NON-EXISTENCE OF OR NEED FOR REMOVAL OF ANY WASTE, HAZARD, OR
CONTAMINANT ON, IN, OR UNDER THE PROPERTY. PURCHASER AGREES THAT IT WILL INSPECT

<PAGE>

        SECTION 7.3    The representations and warranties contained in Section
7.1 hereof shall be true and correct on the date of Closing, and the obligation
of Purchaser to close this transaction is expressly conditioned upon said
representations and warranties being true and correct on the Closing Date,
provided, however, that if Purchaser closes this transaction with actual
knowledge that any representation or warranty is inaccurate, then Purchaser will
have waived any claims as to that representation or warranty. Subject to Section
15.13 hereof, the representations and warranties contained in Section 7.1 hereof
shall survive Closing, and any claim by Purchaser for an alleged breach of any
warranty or representation by Seller must be brought within two years and one
day from said alleged breach. Purchaser must give Seller written notice of said
alleged breach of any warranty or representation within ninety-one (91) days of
the alleged breach. Said notice is a condition precedent to bringing any claim
for said alleged breach, and the failure to give such notice is a waiver of any
claim for such an alleged breach.

        SECTION 7.4    The provisions of Section 7.2 will survive the Closing
and will be included in the Deed and other Closing documents in substantially
the form contained in this Contract.

                                    ARTICLE 8

                              DUE DILIGENCE PERIOD

        SECTION 8.1    Notwithstanding anything to the contrary contained
herein, and in consideration of $100.00 paid by Purchaser to Seller as
independent consideration for this Contract, Purchaser shall have ninety (90)
days after the Effective Date (the "Due Diligence Period") within which to (i)
conduct any and all engineering, environmental, and economic and feasibility
studies and inspections of the Property which Purchaser may, in its sole
discretion, deem necessary to determine whether or not the Property is suitable
for Purchaser's intended use thereof, and (ii) to review all items furnished to
Purchaser pursuant to Article 5 of this Contract. Seller hereby grants to
Purchaser and Purchaser's agents the right to enter upon and conduct such
inspections and studies beginning on the Effective Date until Closing or the
earlier termination of this Contract, and Seller shall exercise reasonable
efforts to, at no cost or expense to Seller, cooperate fully with Purchaser
regarding any investigation Purchaser may wish to make of the Property.
Purchaser agrees to exercise due care and reasonable prudence in performing such
investigations, and may not contact any employees of Seller other than David
Humphreys. If Purchaser does not notify Seller in writing on or before the
expiration of the Due Diligence Period that Purchaser desires to consummate the
transaction contemplated by this Contract, this Contract shall automatically
terminate without further action of either party, the Initial Earnest Money
shall be immediately returned to Purchaser by the Title Company, and the parties
hereto shall have no further obligations one to the other hereunder, except as
to Purchaser's indemnification liability pursuant to this Section 8.1, and as
otherwise provided herein. If Purchaser timely notifies Seller of its acceptance
of the Property, then the Earnest Money shall be non-refundable (and shall be
applied as provided in this Contract), subject only to a Purchaser termination
pursuant to Article 6 or a Seller Default. Purchaser hereby indemnifies, holds
harmless, and agrees to defend Seller from and against any loss, cost, or
expense resulting from any entry by Purchaser, or any agent of Purchaser, upon
the Property or action taken during the Due Diligence Period, or otherwise, or
any lien asserted by any third party as a result thereof. This provision shall
survive the termination of this Contract and Closing.

        SECTION 8.2    PURCHASER ACKNOWLEDGES AND AGREES THAT, IN THE EVENT IT
PURCHASES THE PROPERTY, THAT, AS BETWEEN IT AND SELLER, IT BEARS THE TOTAL
RESPONSIBILITY AND COST OF ANY REMOVAL OF HAZARDOUS SUBSTANCES OR CONTAMINANTS
FROM THE PROPERTY AND OTHER ITEMS CONVEYED THEREWITH. WITHOUT LIMITING THE
FOREGOING, AFTER CLOSING, AS BETWEEN PURCHASER AND SELLER, THE RISK OF LIABILITY
OR EXPENSE FOR ENVIRONMENTAL PROBLEMS, EVEN IF ARISING FROM EVENTS BEFORE
CLOSING, WILL BE THE SOLE RESPONSIBILITY OF

                                       6
<PAGE>

PURCHASER, REGARDLESS OF WHETHER THE ENVIRONMENTAL PROBLEMS WERE KNOWN OR
UNKNOWN AT CLOSING. ONCE CLOSING HAS OCCURRED, PURCHASER RELEASES SELLER FROM
LIABILITY FOR ANY DEFECTS AND FROM ANY LIABILITY FOR ENVIRONMENTAL PROBLEMS
AFFECTING THE PROPERTY, INCLUDING BUT NOT LIMITED TO LIABILITY UNDER THE
COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY ACT (CERLA),
THE RESOURCE CONSERVATION AND RECOVERY ACT (RCRA), THE TEXAS SOLID WASTE
DISPOSAL ACT, OR THE TEXAS WATER CODE. PURCHASER RELEASES SELLER FROM ANY
LIABILITY FOR ENVIRONMENTAL PROBLEMS AFFECTING THE PROPERTY ARISING AS THE
RESULT OF THEORIES OF PRODUCTS LIABILITY AND STRICT LIABILITY, OR UNDER NEW LAWS
OR CHANGES TO EXISTING LAWS ENACTED AFTER THE EFFECTIVE DATE THAT WOULD
OTHERWISE IMPOSE ON SELLER IN THIS TYPE OF TRANSACTION NEW LIABILITIES FOR
ENVIRONMENTAL PROBLEMS AFFECTING THE PROPERTY.

                                    ARTICLE 9

                    CERTAIN PURCHASER'S CONDITIONS PRECEDENT

                (b)     Prior to Closing Seller's continuing to operate and
        maintain the Property in the same manner as Seller has been operating

        so long as each of said New Leases regarding Hotel guests are cancelable
        on 30 days' prior written notice); provided, in the event Purchaser

        thereafter enter into any New Leases whatsoever with Hotel guests.

                (c)     Upon (i) receipt of written notice from Purchaser, given
        at least five (5) days before the expiration of the Due Diligence
        Period, (ii) the deposit of the Additional Earnest Money, and (iii) the
        payment of the Early Termination Fee, as provided below, Seller will
        (except for the Existing Contracts with Reliant Energy and SBC,
        separately addressed in Sections 10.1(f) and (g) below, and except for
        the Existing Lease with Voice Stream, separately addressed in Section
        10.1(e) below) send notices of termination (and copies of same to
        Purchaser) with regard to all Existing Contracts (and New Contracts
        permitted hereby) and Existing Leases (and New Leases permitted hereby);
        Purchaser shall, subject to Section 10(d) hereof, deliver to Seller (to
        be held by Seller, however, pursuant to the terms and conditions of this
        Contract) a $200,000.00 early termination fee (the "Early Termination
        Fee"), said Early Termination Fee to be non-refundable (but applicable
        to the Purchase Price), subject to a Purchaser termination pursuant to
        Article 6 or a Seller Default. Incident to such terminations, and
        subject to Section 10(d) hereof, Seller shall be obligated to timely
        take, at Seller's sole cost and expense (including termination fees and
        legal fees), such reasonable actions as are necessary to insure that all
        contract parties and/or tenants or lessees vacate the Property (and/or
        terminate their respective Existing Contract, New Contract, Existing
        Lease or New Lease, all as applicable) effective as of the applicable
        termination dates. As set forth above, Seller is not required to take
        any action pursuant to this Section 10(c) until such time as Purchaser
        complies with (i), (ii), and (iii) above, but nothing in this Section
        10(c) shall be interpreted as making the deposit of the Additional
        Earnest Money optional with Purchaser.

                (d)     In the event Purchaser does not provide written notice
        and the Early Termination Fee, both as provided in Section 10(c) hereof,
        or fails after giving the notice in Section 8.1 hereof to deposit the
        Additional Earnest Money, then Seller shall be relieved of any
        obligations set forth in Section 10(c) hereof, and in that event,
        Section 14.2 applies, and Purchaser agrees to take full responsibility
        for any performance after Closing of any existing Contracts, New
        Contracts, Existing Leases, or New Leases. However, provided that the
        Purchaser has deposited the Additional Earnest Money in a timely manner
        after having given the notice provided in Section 8.1 hereof, Purchaser
        may, at any time at least five (5) days prior to Closing, give the
        written notice and pay the Early Termination Fee, both as described in
        Section 10(c) hereof, and in that event, Seller will send the notices
        described in Section 10(c) hereof, and further, Seller will have the
        responsibility at its sole cost, to take such reasonable actions as are
        necessary to ensure the removal of any contract or lease obligation for
        which Seller's notice triggers a termination date that is prior to
        Closing. As to any contract or lease obligation to which Seller's notice
        triggers a termination date that is after Closing, Purchaser shall be
        responsible for, at its sole cost, taking such actions as it deems
        necessary to remove such obligations, and Section 14.2 shall apply. The

        reference to contracts and leases in here specifically excludes the
        existing contracts with Reliant Energy and SBC, and the existing lease
        with VoiceStream.

                (e)     Purchaser has been informed that Seller has sent one (1)
        or more notices terminating the Existing Leases with Voice Stream due to
        a default by Voice Stream thereunder. Notwithstanding anything contained
        herein to the contrary, Seller acknowledges and agrees that , in the
        event Voice Stream does not, within thirty (30) days after the Effective
        Date, acquiesce in writing as to such termination, Purchaser may attempt
        to negotiate modifications (reasonably acceptable to Seller) to said
        Existing Lease directly with representatives of Voice Stream; provided,
        if Purchaser is unable to obtain such modifications prior to the
        expiration of the Due Diligence Period, Seller understands that
        Purchaser may, at its option, terminate this Contract on or before the
        expiration of the Due Diligence Period and receive the immediate return
        of the Initial Earnest Money Deposit; provided further, however, in the
        event Purchaser does not timely terminate this Existing Lease due to
        same, Purchaser shall at the Closing (assuming Voice Stream has not,
        prior to the Closing, acquiesced in writing to the termination of its
        Existing Lease) assume the Existing Lease with Voice Stream.

                (f)     With regard to the Existing Contract with Reliant
        Energy, Seller acknowledges and agrees that Purchaser may attempt to
        negotiate modifications (reasonably acceptable to Seller) to said
        Existing Contract directly with representatives of Reliant Energy;
        provided, if Purchaser is unable to obtain such modifications prior to
        the expiration of the Due Diligence Period, Seller understands that
        Purchaser may, at its option, terminate this Contract on or before the
        expiration of the Due Diligence Period and receive the immediate return
        of the Initial Earnest Money Deposit; provided further, however, in the
        event Purchaser does not timely terminate this Existing Contract due to
        same, Purchaser shall at the Closing assume the Existing Contract with
        Reliant Energy.

                (g)     With regard to the Existing Contract with SBC, Seller
        acknowledges and agrees that Purchaser may attempt to negotiate
        modifications (reasonably acceptable to Seller) to said Existing
        Contract directly with representatives of SBC; provided, if Purchaser is
        unable to obtain such modifications prior to the expiration of the Due
        Diligence Period, Seller understands that Purchaser may, at its option,
        terminate this Contract on or before the expiration of the Due Diligence
        Period and receive the immediate return of the Initial Earnest Money
        Deposit; provided further, however, in the event Purchaser does not
        timely terminate this Existing Contract due to same, Purchaser shall at
        the Closing assume the Existing Contract with SBC.

kind or character arising from any claims for brokerage or finder's fees,
commissions or other similar fees in connection with the transactions covered by

                               REMEDIES ON DEFAULT

        SECTION 13.1    If Seller fails in the performance of any of its
material obligations hereunder, including a breach of its representations and
warranties contained herein ("Seller Default"), then Purchaser shall either (i)
terminate this Contract and accept the return of the Earnest Money and the Early
Termination Fee, as applicable, and, except as otherwise provided in this
Agreement, neither party shall thereafter have any further obligations
hereunder, or (ii) sue for specific performance, as its sole and exclusive
remedies. Subject to Section 7.3 hereof, Purchaser hereby waives the right to
bring a suit for damages (including a suit for consequential damages or lost
profits), and waives all other remedies at law or in equity. Notwithstanding the
foregoing, it shall not be considered a Seller Default hereunder in the event a
contracting party or tenant or lessee under any Existing Contract, New Contract,
Existing Lease or New Lease does not receive a termination notice letter herein
required, so long as such notices were sent or delivered in a manner reasonably
acceptable to Seller (and assuming Purchaser has received copies of any such
termination notice). Additionally, and notwithstanding the foregoing, Purchaser
may not sue Seller for specific performance if the Seller Default in question
was caused by circumstances beyond the reasonable control of Seller. In the
event Purchaser elects to sue for specific performances, Purchaser must notify
Seller in writing of its intention to do so within ninety-one (91) days after
the occurrence of the Seller Default and commence a legal action with respect
therefore within two years and one day after the occurrence of such Seller
Default. Such notice shall be a condition precedent to any action for specific
performance, and a failure to timely give such notice shall be deemed to be a
waiver of the rights of Purchaser to claim specific performance.

        SECTION 13.2    If Purchaser fails in the performance of any of its
material obligations hereunder ("Purchaser Default"), then the Earnest Money
shall be paid to Seller by the Title Company (and Seller shall be entitled to
retain the Early Termination Fee, as applicable) as liquidated damages for such
Purchaser Default as Seller's sole and exclusive remedy, except as otherwise set
forth in this Agreement, and neither party shall thereafter have any further
obligations hereunder (except as otherwise provided herein). The parties agree
that the amount of liquidated damages described in the preceding sentences, as
applicable, is a reasonable sum considering all of the circumstances existing as
of the date hereof, including the relationship of such sum to the amount of harm
to Seller that reasonably could be anticipated, Seller's anticipated use of the
proceeds of sale and the fact that actual damages would be impossible to
determine.

                                 INDEMNIFICATION

        SECTION 14.1    Except as otherwise set forth in this Agreement, and
except to the extent caused by the negligence or willful misconduct of
Purchaser, Seller hereby agrees to indemnify, protect, defend, save and hold
harmless Purchaser, and Purchaser's employees, officers, directors, partners,
members and shareholders, from and against any and all debts, duties,
obligations, liabilities, suits, claims, demands, causes of action, damages,
losses, costs and expenses (including, without limitation, reasonable attorneys'
fees, expenses and court costs) in any way relating to, connected with, or
arising out of the Property and/or the ownership, leasing, use, operation,
maintenance, or management thereof, and which arise or accrue out of facts and
circumstances occurring prior to the Closing Date. The provisions of this
Section 14.1 shall survive Closing and are not subject to the restrictions on
claims and remedies set out in Section 13.1 hereof, but are subject to Section
15.13 hereof.

Seller, and Seller's employees, officers, directors, partners and shareholders,
from and against any and all debts, duties, obligations, liabilities, suits,
claims, demands, causes of action, damages, losses, costs and expenses
(including, without limitation, attorney's fees and expenses and court costs) in
any way relating to, connected with, or arising out of the Property or the
ownership, leasing, use, operation, maintenance, or management thereof, which
arise or accrue out of facts and circumstances occurring after the Closing Date.
The provisions of this Section 14.2 shall survive Closing and are not subject to
the restrictions on claims and remedies set out in Section 13.2 hereof, but are
subject to Section 15.13 hereof.

                                    EXHIBIT D

        UNITED ELEVATOR SERVICES:

        $3,010.01 from June 2001 for services that were not rendered. Notice was
        given that we did not intend to pay and as far as I know, they did not
        respond.

        FRYMIRE ENGINEERING COMPANY:

        $473.05 from August 2002 for disputed services.

        KAHN MECHANICAL:

        $4,105.81 from March 2004 for services which resulted in damage to the
        chiller unit they were here to service.

        TXU:

        $100,000 from June - September 2002 for disputed utility charges. They
        have admitted billing irregularities as well as suspicious change of
        meter 3 months before deregulation which disallowed the Hotel from
        switching service providers and saving considerable money. It took 9
        months to switch providers due to the meter during which time we paid
        about 40% more in electric charges. We are hoping to settle in the next
        couple of months.

        CITY OF DALLAS:

        Original outstanding bill was over $43,000 for occupancy taxes which we
        have been paying off since August 2003. Our last payment will be made
        the first week of July 2004.

opposite their respective names on EXHIBIT C attached hereto and made a part

Expenses or for any other purpose (collectively, "CASH NEEDS"), then the General
Partner shall use reasonable efforts to secure third party or Partner loans to
fulfill such Cash Needs. If such efforts to secure third party or Partner loans

notice ("ADDITIONAL CAPITAL NOTICE") requesting that the Limited Partners,

necessary to satisfy such Cash

                                       8
<PAGE>

Needs and describing the purpose for which the funds are needed. If so

make an Additional Capital Contribution equal to the product of its Residual
Percentage and the amount of the Cash Needs. The time for the payment of any
Additional Capital Contribution to the Partnership shall be determined by the
General Partner, but shall in no event be less than fifteen (15) days after the
delivery of the Additional Capital Notice.

        3.3     FAILURE TO MAKE CAPITAL CONTRIBUTION.

                (a)     If the General Partner or a Limited Partner fails to
timely contribute all or any portion of any Initial Capital Contribution or
Additional Capital Contribution required of such Partner, then such Partner
shall be considered a "DELINQUENT PARTNER." The Partnership may, upon notice to
a Delinquent Partner, exercise either one of the following remedies as its sole
remedy:

                        (i)     permit the non-Delinquent Partner(s) to advance
that portion of the required Capital Contribution that is in default as a loan
(a "DEFAULT LOAN") with the following results: (A) the sum thus advanced shall
constitute a loan to the Delinquent Partner; (B) such loan and all accrued
unpaid interest thereon shall be due on demand, or if no demand is made, twelve
(12) months after such advance is made; (C) the loan shall bear interest at the
lesser of twelve percent (12%) per annum or the highest rate permitted by
applicable law, from the date made until the date fully repaid compounding
monthly; (D) all Partnership distributions and other payments that otherwise
would be made to the Delinquent Partner (whether before or after dissolution of
the Partnership) under this Agreement (including those under Article 6) shall be
paid to the non-Delinquent Partner until the loan and all interest accrued
thereon is paid in full (with all such payments being applied first to accrued
and unpaid interest and then to principal and being deemed to be a distribution
or payment (as may apply) to the Delinquent Partner, and, in turn, a payment by
the Delinquent Partner with respect to the loan from the non-Delinquent
Partner); and (E) the non-Delinquent Partner may, in addition to the other
rights granted herein, take such action as the non-Delinquent Partner may deem
appropriate to obtain payment of the loan at the expense of the Delinquent
Partner; or

                        (ii)    permit the non-Delinquent Partner to contribute
the Capital Contribution not made by the Delinquent Partner as a Capital
Contribution made by the non-Delinquent Partner, in which case the
non-Delinquent Partner shall have its Residual Percentage increased and the
Delinquent Partner shall have its Residual Percentage decreased in the following
manner: (A) if the Capital Contribution not made by the Delinquent Partner and
made by the non-Delinquent Partner is an Initial Capital Contribution, then (1)
the Residual Percentage of the non-Delinquent Partner immediately following such
Capital Contribution shall be increased by an amount equal to 175% x A/B
(expressed as a percentage), where `A' equals the amount the non-Delinquent
Partner contributed in respect of the Delinquent Partner's required Initial
Capital Contribution, and `B' equals the sum of all unreturned Capital
Contributions previously made to the Partnership after giving effect to the
amounts advanced under this Section 3.3(a)(ii) on behalf of the Delinquent
Partner; and (2) the Residual Percentage of the Delinquent Partner shall be
decreased by the increase of the non-Delinquent Partner's Residual Percentage;
and (B) if the Capital Contribution not made by the Delinquent Partner and made
by the non-Delinquent Partner is an Additional Capital Contribution, then (1)
the Residual Percentage of the non-Delinquent Partner immediately following such
Capital Contribution shall be increased by an amount equal to 125% x A/B
(expressed as a percentage), where `A' equals the amount the non-Delinquent
Partner contributed in respect of the Delinquent Partner's required Additional
Capital Contribution, and `B' equals the sum of all unreturned Capital
Contributions previously made to the Partnership after giving effect to the
amounts advanced under this Section 3.3(a)(ii) on behalf of the Delinquent
Partner; and (2) the Residual Percentage of the Delinquent Partner shall be
decreased by the increase of the non-Delinquent Partner's Residual Percentage.
An example of the operation of this Section 3.3(a)(ii) is attached hereto as
EXHIBIT D.

                                       9
<PAGE>

                (b)     The exercise by the Partnership of the remedies set
forth in Section 3.3(a) above shall be determined by the non-Delinquent Partners
in their sole discretion and not by the Delinquent Partners.

                (c)     With respect to any efforts by the General Partner to
obtain loans to the Partnership from a third party or a Partner (including the
General Partner), the financing terms must be substantially similar to (or more
favorable than) loans which the Partnership could obtain on a competitive
arms-length basis. If the General Partner is unable to determine whether the
financing terms are competitive on an arms-length basis, the General Partner may
seek a Partnership Vote on the issue, or may seek and rely upon the advice of an
independent expert in financing. If any Partner makes any loan or loans to the
Partnership or advances money on its behalf, the amount of any loan or advance
shall not be treated as a Capital Contribution but shall be treated as a debt
due from the Partnership to such Partner.

        3.4     CAPITAL ACCOUNTS. The Partnership shall establish and maintain
on its books and records for each Partner a capital account (collectively the
"CAPITAL ACCOUNTS") in accordance with Section 1.704-1(b)(2)(iv) of the
Regulations. Subject to the foregoing, each Partner's Capital Account generally
shall be:

                (a)     increased by (i) the amount of money contributed by such
Partner to the Partnership, including Partnership liabilities assumed by such
Partner; (ii) the fair market value of property (net of liabilities securing
such property that the Partnership has assumed, or taken subject to, under
Section 752 of the Code), or other consideration contributed by such Partner to
the Partnership; and (iii) allocations to such Partner of Net Profits (and items
thereof, including certain tax exempt income) and income and gain described in
Section 1.704-1(b)(2)(iv)(g) of the Regulations; and

                (b)     decreased by (i) the amount of money distributed to such
Partner by the Partnership, including such Partner's individual liabilities
assumed by the Partnership; (ii) the fair market value of all property
distributed to such Partner by the Partnership (net of liabilities that such
Partner is considered to assume or take subject to under Section 752 of the
Code); and (iii) allocations to such Partner of Net Losses and deductions,
including expenses described in Section 705(a)(2)(B) of the Code which are not
deductible for tax purposes.

        3.5     INTEREST ON AND WITHDRAWAL OF CAPITAL CONTRIBUTIONS. Neither the
General Partner nor the Limited Partners shall be entitled to receive any
interest on Capital Contributions, nor shall the General Partner or the Limited
Partners be entitled to withdraw or otherwise receive a return of their Capital
Contributions from the Partnership, except pursuant to the terms and conditions
of this Agreement. No Partner shall be required to contribute or lend any cash
or property to the Partnership to enable the Partnership to return any Partner's
Capital Contributions.

by this Agreement, no Partner may resign or withdraw from the Partnership

Capital Account of the Transferor to the extent it relates to the Transferred
interest.

incidental to, the development and operation of the Property as may be lawfully
carried on or performed by a limited partnership under the laws of each state in
which the Partnership is then formed, qualified, or does business.

Partnership to incur the expenditures and obligations therein provided. The
General Partner shall submit (or request the manager of the Property to submit)
to the Limited Partners any proposed Operating Budget for each calendar year by

                                       13
<PAGE>

Majority in Interest by January 1 of that year, the Partnership shall continue
to operate under the Operating Budget for the previous year with such
adjustments as may be necessary to reflect deletion of non-recurring expense
items set forth on the previous Operating Budget and increased insurance costs,
taxes, utility costs, and debt service payments.

        4.6     LIMITED PARTNER PARTICIPATION IN MANAGEMENT. The Limited
Partners, as limited partners, shall not participate in the operation or

in the name of the Partnership, and the Limited Partners, as the limited
partners, shall not have any right or power to sign for or bind the Partnership
in any manner, except as expressly provided under the provisions of this
Agreement. Any rights of the Limited Partners to consent to and approve of
certain matters under the provisions of this Agreement shall not be deemed a
participation in the operation and management of the business of the Partnership
or the exercise of control of the Partnership business. Except as may be
otherwise expressly provided herein, the Limited Partners shall not have the
right to vote on any matter concerning the management and affairs of the
Partnership.

        4.7     PAYMENT OF COSTS AND EXPENSES. The Partnership will be
responsible for paying all costs and expenses of forming and continuing the
Partnership, acquiring the Property, and conducting the business of the
Partnership, including, without limitation, accounting costs, legal expenses and
office supplies. In the event any such costs and expenses are incurred and paid
by the General Partner on behalf of the Partnership, then, except as expressly
provided to the contrary in this Agreement, such Partner shall be entitled to be
reimbursed for such payment so long as such cost or expense was reasonably
necessary and is reasonable in amount. The Partnership may use the proceeds of
any revenues of the Partnership to reimburse a Partner for any such costs and
expenses so paid.

        4.8     TRANSACTIONS WITH AFFILIATES. Any agreement whereby any service
or activity to be performed for the Partnership is to be performed by an
Affiliate of a Partner shall require Approval by a Partnership Vote. The
Partners hereby acknowledge and agree that Approval by Partnership Vote has been
obtained with respect to the Management Agreement and the Development Agreement.

        4.9     FEES PAYABLE BY THE PARTNERSHIP.

                (a)     Upon the acquisition of the Property, the Partnership

(1%) of the purchase price for the Property (as defined in the Purchase
Agreement).

Agreement with Developer to perform development services in respect of the

                (c)     If a guaranty by BH Investors or any affiliated entity
(a "BH GUARANTOR") is required in order to obtain a Mortgage Loan, and if the BH
Guarantor elects to execute such a guaranty (which election shall be made in the
sole discretion of the BH Guarantor), then, upon the closing of such Mortgage
Loan, Realty America shall pay to the BH Guarantor a guaranty fee equal to the
product obtained by multiplying the original principal amount of the Mortgage
Loan by one-half of one percent (.05%). The Partnership hereby agrees to
indemnify any BH Guarantor against any losses, judgments, liabilities, expenses
and amounts paid in settlement of any claims sustained by it in connection with
any such guaranty, and any such amounts paid by a BH Guarantor shall be included
in calculating whether the Maximum BH Investors Contribution Amount has been
attained.

                (d)     The Partnership shall contract with HPT for HPT to
perform management services in respect of the Property in accordance with the
Management Agreement, pursuant to which

HPT will receive the management fee and other fees from the Partnership as set
forth in the Management Agreement.

                (e)     The Partners acknowledge and agree that HPT will
subcontract with an Affiliate of Realty America to perform certain management
services in respect of the Property. Furthermore, the Partners acknowledge that
HPT may subcontract (or the Partnership may contract directly) with an Affiliate
of Realty America to perform leasing services in respect of the Project.

                (f)     Subject to the final sentence of this Section 4.9(f),
the Partnership shall pay to Behringer Harvard Advisors II LP, an affiliate of
the General Partner, an annual asset management fee (the "ASSET MANAGEMENT FEE")
equal to one-half of one percent (0.5%) of the aggregate book value of the
assets of the Partnership (other than investments in bank accounts, money market
funds and other current assets) at the time of measurement before deducting
depreciation, bad debts, other similar non-cash reserves and without reduction
for any debt secured by or relating to such assets. The Asset Management Fee
will be payable on the tenth (10th) day of each month in an amount equal to
one-twelfth of one-half percent (1/12 of .5%) of the value of the Partnership's
assets (calculated pursuant to the preceding sentence) as of the last day of the
immediately preceding month. Notwithstanding the foregoing provisions, in no
event shall the Asset Management Fee paid to Behringer Harvard Advisors II LP
exceed an amount equal to one percent (1%) of the costs of developing the
Property.

                (g)     The Partnership shall pay to Realty America and
Behringer Harvard Advisors II LP (or its designated Affiliate) a market rate
sales commission upon the sale of the Property, payable if and when the closing
of the sale of the Property occurs, with eighty percent (80%) of such fee being
paid to Realty America and twenty percent (20%) of such fee being paid to
Behringer Harvard Advisors II LP (or its designated Affiliate).

        4.10    OTHER COMPENSATION. Except as provided in this Agreement, no
Partner or its Affiliate shall be entitled to any compensation unless Approval
by Partnership Vote is obtained with respect thereto.

        4.11    CONSTRUCTION REQUIREMENTS. The completion of improvements which
are to be constructed on the Property shall be guaranteed at the price
contracted either by an adequate completion bond or by other assurances
satisfactory to the General Partner, which assurances shall include one or more
(at the discretion of the General Partner) of the following: (a) a written
personal guarantee of one or more of the general contractor's principals
accompanied by the financial statements of such guarantor indicating a
substantial net worth; (b) a written fixed price contract with a general
contractor that has a substantial net worth; (c) a retention of a reasonable
portion of construction costs as a potential offset to such construction costs
in the event the general contractor does not perform in accordance with the
construction contract; or (d) a program of disbursements control which provides
for direct payments to subcontractors and suppliers. The Partnership shall make
no periodic progress or other advance payments to the general contractor or any
subcontractor unless the Partnership has first received an architect's
certification as to the percentage of the improvements which has been completed
and as to the dollar amount of the construction then completed.

        4.12    PROJECT MANAGERS. The Partnership shall have no employees. Each

                          RIGHTS AND POWERS OF PARTNERS

        5.1     LIMITATION OF LIABILITY.

                (a)     LIMITATION ON LIABILITY OF LIMITED PARTNERS. The Limited
Partners shall not be bound by, or personally liable for, obligations or
liabilities of the Partnership to outside third parties beyond the amount of
their Capital Contributions to the Partnership, and the Limited Partners shall
not be required to contribute any capital to the Partnership for any obligations
to third parties in excess of the Capital Contributions actually made under
Sections 3.1 and 3.2 hereof.

                (b)     LIMITATION ON LIABILITY OF GENERAL PARTNER. The General
Partner (including its members, officers, directors, agents, employees and
representatives) shall not be liable or responsible in damages or otherwise to
the Partnership or any Partner for any liability or loss relating to the
performance or nonperformance of any act concerning the business of the
Partnership, provided the General Partner was not guilty of gross negligence or
willful misconduct.

        5.2     INDEMNIFICATION.

                (a)     The General Partner (including its members, partners,
officers, directors, agents, employees and representatives) shall be indemnified
by the Partnership to the fullest extent permitted by law, against any losses,
judgments, liabilities, expenses and amounts paid in settlement of any claims
sustained by it or any of them in connection with the Partnership, provided that
the General Partner has determined in good faith that such course of conduct was
in, and not opposed to, the best interests of the Partnership and such liability
or loss was not the result of gross negligence or willful misconduct, or a
material breach of this Agreement on the part of the General Partner or such
person, and (2) any such indemnification will only be recoverable from the
assets of the Partnership and the Limited Partners shall not have any liability
on account thereof. All rights to indemnification permitted herein and payment
of associated expenses shall not be affected by the dissolution or other
cessation of the existence of the General Partner, or the withdrawal,
adjudication of bankruptcy or insolvency of the General Partner.

                (b)     Expenses incurred in defending a threatened or pending
civil, administrative or criminal action, suit or proceeding against any person
who may be entitled to indemnification pursuant to this Section 5.2 may be paid
by the Partnership in advance of the final disposition of such action, suit or
proceeding, if (i) the legal action relates to the performance of duties or
services by such person on behalf of the Partnership, (ii) the legal action is
initiated by a third party who is not a Limited Partner, and (iii) such person
undertakes to repay the advanced funds to the Partnership in cases in which it
is not entitled to indemnification under this Section 5.2.

                (c)     The term "General Partner" as used in this Section 5.2
shall include any additional or substitute general partner and any Affiliate of
a General Partner performing services on behalf of the Partnership.

        5.3     OTHER BUSINESS ACTIVITIES. Subject to the other express
provisions of this Agreement, each Partner and any Affiliate thereof may engage
in and possess interests in other business ventures of any and every type and
description, independently or with others, including ones in direct or indirect
competition with the Partnership, with no obligation to offer to the Partnership
or any other Partner the right to participate therein or to account therefor.

                                       16
<PAGE>

        5.4     INFORMATION. In addition to the other rights specifically set
forth in this Agreement, each Partner is entitled to the following information:
(a) true and full information regarding the status of the business and financial
condition of the Partnership; (b) promptly after becoming available, a copy of
the Partnership's federal, state and local income tax returns for each year; (c)
a current list of the name and last known business, residence or mailing address
of each Partner; (d) a copy of this Agreement, the Certificate, and all
amendments to such documents; and (e) other information regarding the affairs of
the Partnership to which that Partner is entitled pursuant to the TRLPA.

        5.5     PRESS RELEASES. No public announcement, press release or other
similar public disclosure of the terms of this Agreement, the activities of the
Partnership, or the plans of the Partnership will be made unless same is
proposed by the General Partner and authorized by Approval by Partnership Vote.
However, notwithstanding the preceding sentence, any Partner shall have the
right, without obtaining the consent of any other Partner, to make such
disclosures as may, in the reasonable judgment of such Partner's counsel, be
required by applicable law. Furthermore, it is agreed that the foregoing
provisions of this Section 5.5 shall not prohibit a Partner from disclosing such
information to the accountants, attorneys, consultants, lenders and vendors of
the Partnership as is necessary to allow such parties to provide services, funds
or goods to the Partnership. The Partners have agreed that if a Partner breaches
the obligation set forth in the first sentence of this Section 5.5 (the
"NON-DISCLOSURE OBLIGATION"), the actual damages that will be incurred by the
other Partners as a result of such breach would be extremely difficult or
impracticable to determine. Therefore, the Partners agree that if a Partner or
any Affiliate of a Partner breaches the Non-Disclosure Obligation, such Partner
shall pay to each of the other Partners liquidated damages (the "LIQUIDATED
DAMAGES") in the amount of Fifty Thousand Dollars ($50,000) for each such
breach, such amount having been agreed upon, after negotiation, as the Partners'
reasonable estimate of the damages that will be suffered by reason of a breach
of the Non-Disclosure Obligation. Any Liquidated Damages becoming payable
pursuant to this Section 5.5 shall be paid within ten (10) days after the breach
of the Non-Disclosure Obligation giving rise to the Liquidated Damages. If not
paid within such ten (10) day period, the Liquidated Damages shall thereafter
bear interest at the lesser of twelve percent (12%) per annum or the highest
rate permitted by applicable law. All Partnership distributions and other
payments that otherwise would be made to the Partner that is liable for
Liquidated Damages shall be paid to the other Partners until the Liquidated
Damages and all interest accrued thereon are paid in full (with all such
payments being applied first to accrued and unpaid interest and then to the
Liquidated Damages).

                                  ARTICLE VI.

                 DISTRIBUTIONS/ALLOCATIONS OF PROFITS AND LOSSES

        6.1     DISTRIBUTIONS OF DISTRIBUTABLE CASH. Within twenty (20) days
following the end of each month (unless Approval by Partnership Vote is
otherwise obtained), the Partnership shall distribute Distributable Cash in the
following order of priority:

                (a)     First, to the Partners in proportion to their respective
Additional Capital Contribution Account balances until their respective
Additional Capital Contribution Account balances are reduced to zero;

                (b)     Next, to the Partners in proportion to their respective
Initial Capital Contribution Account balances until their respective Initial
Capital Contribution Account balances are reduced to zero; and

                (c)     Next, to the Partners, pro rata in accordance with their
Residual Percentages (as calculated pursuant to clause (b) of the definition of
such term).

                                  ARTICLE VII.

                        ALLOCATION OF PROFITS AND LOSSES

        7.1     ALLOCATION OF PROFITS AND LOSSES. After application of Section
7.3 hereof, Profits and Losses for each fiscal year shall be allocated among the
Partners so as to reduce, proportionately, in the case of any Profits, the
difference between their respective Target Accounts and Partially Adjusted
Capital Accounts for such fiscal year and, in the case of Losses, the difference
between their respective Partially Adjusted Capital Accounts and Target Accounts
for such fiscal year. To the extent that, in the fiscal year in which all or
substantially all of the Partnership's assets are disposed of, or in the fiscal
year in which the Partnership is liquidated, the allocation of Profit or Loss
set forth in the preceding sentence does not cause each Partner's Partially
Adjusted Capital Account balance to equal the balance of its Target Account,
items of income or gain will be reallocated to any Partner with a Partially
Adjusted Capital Account which is less than its Target Account, and items of
loss, deduction or expense will be reallocated to any Partner with a Partially
Adjusted Capital Account that is greater than its Target Account in such manner
as to reduce, to the greatest extent possible, the difference between each
Partner's respective balance in its Target Account and its Partially Adjusted
Capital Account balance.

        7.2     LIMITATION ON LOSS ALLOCATIONS. Notwithstanding anything in this
Agreement to the contrary, no Losses or item of deduction shall be allocated to
a Partner if such allocation would cause the Capital Account of such Partner to
have a deficit in excess of the sum of (a) the amount of additional capital such
Partner would be required to contribute to the Partnership if the Partnership
were to dissolve on the last day of the accounting period to which such
allocation relates plus (b) such Partner's distributive share of Partnership
Minimum Gain as of the last day of such accounting period, determined pursuant
to Regulations Section 1.704-2(g)(1), plus (c) such Partner's share of Partner
Minimum Gain as of the last day of such year, determined pursuant to Regulation
Section 1.704-2(i)(5). Any amounts not allocated to a Partner pursuant to the
limitations set forth in this paragraph shall be allocated to the other Partners
to the extent possible without violating the limitations set forth in this
paragraph. For purposes of the foregoing provisions, the balance of a Partner's
Capital Account shall be determined after reducing such Capital Account by (i)
all anticipated allocations of loss or deduction pursuant to Sections 704(e)(2)
and 706(d) of the Code, and Section 1.751-1(b)(2)(ii) of the Regulations, and
(ii) anticipated distributions to such Partner to the extent such anticipated
distributions exceed anticipated increases to such Partner's Capital Account
during or prior to the year of distribution (other than increases which may not
be taken into account pursuant to Section 1.704-1(b)(2)(ii)(d)(6) of the
Regulations).

        7.3     SPECIAL ALLOCATIONS. The following special allocations shall be
made in the following order:

                (a)     MINIMUM GAIN CHARGEBACK. Except as otherwise provided in
Section 1.704-2(f) of the Regulations, in the event there is a net decrease in
Partnership Minimum Gain during a Partnership taxable year, each Partner shall
be allocated (before any other allocation is made pursuant to this Section 7.3)
items of income and gain for such year (and, if necessary, for subsequent years)
equal to that Partner's share of the net decrease in Partnership Minimum Gain.
The determination of a Partner's share of the net decrease in Partnership
Minimum Gain shall be determined in accordance with Regulations Section
1.704-2(g). The items to be specially allocated to the Partners in accordance
with this Section 7.3(a) shall be determined in accordance with Regulation
Section 1.704-2(f)(6). This Section 7.3(a) is intended to comply with the
Minimum Gain chargeback requirement set forth in Section 1.704-2(f) of the
Regulations and shall be interpreted consistently therewith.

                (b)     PARTNER MINIMUM GAIN CHARGEBACK. Except as otherwise
provided in Section 1.704-2(i)(4), in the event there is a net decrease in
Partner Minimum Gain during a Partnership

                                       18
<PAGE>

taxable year, each Partner who has a share of that Partner Minimum Gain as of
the beginning of the year, to the extent required by Regulation Section
1.704-2(i)(4), shall be specially allocated items of Partnership income and gain
for such year (and, if necessary, subsequent years) equal to that Partner's
share of the net decrease in Partner Minimum Gain. Allocations pursuant to this
subparagraph (b) shall be made in accordance with Regulation Section
1.704-2(i)(4). This Section 7.3(b) is intended to comply with the requirement
set forth in Regulation Section 1.704-2(i)(4) and shall be interpreted
consistently therewith.

                (c)     QUALIFIED INCOME OFFSET ALLOCATION. In the event any
Partner unexpectedly receives any adjustments, allocations or distributions
described in Regulation Sections 1.704-1(b)(2)(ii)(d)(4),
1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6) or which would cause the
negative balance in such Partner's Capital Account to exceed the sum of (i) his
obligation to restore a Capital Account deficit upon liquidation of the
Partnership, plus (ii) his share of Partnership Minimum Gain determined pursuant
to Regulation Section 1.704-2(g)(1), plus (iii) such Partner's share of Partner
Minimum Gain determined pursuant to Regulation Section 1.704-2(i)(5), items of
Partnership income and gain shall be specially allocated to such Partner in an
amount and manner sufficient to eliminate such excess negative balance in his
Capital Account as quickly as possible. This Section 7.3(c) is intended to
comply with the alternative test for economic effect set forth in Regulation
Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

                (d)     GROSS INCOME ALLOCATION. In the event any Partner has a
deficit Capital Account at the end of any Partnership fiscal year which is in
excess of the sum of (i) any amounts such Partner is obligated to restore
pursuant to this Agreement, plus (ii) such Partner's distributive share of
Minimum Gain as of such date, plus such Partner's share of Partner Minimum Gain
determined pursuant to Regulation Section 1.704-2(i)(5), each such Partner shall
be specially allocated items of Partnership income and gain in the amount of
such excess as quickly as possible, provided that an allocation pursuant to this
Section 7.3(d) shall be made only if and to the extent that such Partner would
have a deficit Capital Account in excess of such sum after all other allocations
provided for in this Section 7.3 have been made, except assuming that Section
7.3(c) above and this Section 7.3(d) were not contained in this Agreement.

                (e)     ALLOCATION OF NONRECOURSE DEDUCTIONS. Nonrecourse
Deductions shall be allocated to the Partners in accordance with their
respective Residual Percentages.

                (f)     ALLOCATION OF PARTNER NONRECOURSE DEDUCTIONS. Partner
Nonrecourse Deductions shall be allocated as prescribed by the Regulations.

                (g)     BASIS ADJUSTMENT UNDER SECTION 754. To the extent an
adjustment to the adjusted tax basis of any Partnership assets pursuant to Code
Section 734(b) or Code Section 743(b) is required, pursuant to Regulations
Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital
Accounts, the amount of such adjustment to the Capital Accounts shall be treated
as an item of gain, if the adjustment increases the basis of the asset, or loss,
if the adjustment decreases such basis, and such gain or loss shall be specially
allocated to the Partners in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such Section of the
Regulations.

        7.4     BUILT-IN GAIN OR LOSS/SECTION 704(C) TAX ALLOCATIONS. In the
event that the Capital Accounts of the Partners are credited with or adjusted to
reflect the Gross Asset Value of the Partnership's property and assets, the
Partners' distributive shares of depreciation, depletion, amortization, and gain
or loss, as computed for tax purposes, with respect to such property, shall be
determined pursuant to Section 704(c) of the Code and the Regulations
thereunder, so as to take account of the variation between the adjusted tax
basis and Gross Asset Value of such property in a manner determined by Approval
by Partnership Vote. Any deductions, income, gain or loss specially allocated

                                       19
<PAGE>

pursuant to this Section 7.4 shall not be taken into account for purposes of
determining Profits or Losses or for purposes of adjusting a Partner's Capital
Account.

        7.5     RECAPTURE. Ordinary income arising from the recapture of
depreciation and unrecaptured Section 1250 gain shall be allocated to the
Partners in the manner that is prescribed by the Regulations, or if the
Regulations do not prescribe a manner in which depreciation is to be recaptured,
then depreciation shall be recaptured in the same manner as such depreciation
was allocated to the Partners.

        7.6     RETENTION OF SECTION 751 ASSETS. Upon the occurrence of an event
which would otherwise cause a reduction in a Partner's respective interest in
the Partnership's Section 751 assets ("substantially appreciated inventory" and
"unrealized receivables" as defined in Section 751 of the Code), such as the
admission of new Partners or otherwise, no such reduction shall occur with
respect to Partners who were Partners immediately preceding such event and who
continue to be Partners after the occurrence of such event but, rather, each
such Partner shall retain his respective interest in the Partnership's Section
751 assets existing immediately prior to such event.

        7.7     PROHIBITION AGAINST RETROACTIVE ALLOCATIONS. Notwithstanding
anything in this Agreement to the contrary, no Partner shall be allocated any
loss, credit or income attributable to a period prior to his admission to the
Partnership. In the event that a Partner Transfers all or a portion of his
Partnership interest, or if there is a reduction in a Partner's Residual
Percentage due to the admission of new Partners or otherwise, each Partner's
distributive share of Partnership items of income, loss, credit, etc., shall be
determined by taking into account each Partner's varying interests in the
Partnership during the Partnership's taxable year. For this purpose, each
Partner's distributive share shall be estimated by taking the pro rata portion
of the distributive share such Partner would have included in his taxable income
had he maintained his Residual Percentage throughout the Partnership year. Such
proration shall be based upon the portion of the year during which such Partner
held the Residual Percentage, except that extraordinary, nonrecurring items
shall be allocated to the persons holding Partnership interests at the time such
extraordinary items occur.

        7.8     ALLOCATION OF NONRECOURSE LIABILITIES. The "excess nonrecourse
liabilities" of the Partnership (within the meaning of Section 1.752-3(a)(3) of
the Regulations) shall be allocated to the Partners in accordance with their
respective Residual Percentages.

                                 ARTICLE VIII.

                        TRANSFER OF PARTNERSHIP INTEREST

        8.1     PROHIBITION ON DISPOSITION OF GENERAL PARTNER'S INTEREST. Unless
Approval by Partnership Vote is otherwise obtained, or except as otherwise
permitted in this Agreement, the General Partner may not, directly or
indirectly, by operation of law or otherwise (a) withdraw or resign from the
Partnership, or (b) Transfer any or all of its interest in the Partnership. In
addition, the General Partner shall not permit the Transfer of any interest in
the General Partner unless Approval by Partnership Vote is obtained with respect
to such Transfer. Any act in violation of this Section 8.1 shall be null and
void as against the Partnership and the Limited Partners, except as otherwise
required by law.

        8.2     GENERAL PARTNER CEASING TO BE A GENERAL PARTNER. Unless Approval
by Partnership Vote is otherwise obtained, a General Partner shall cease to be a
General Partner of the Partnership upon the happening of any of the following
events (hereinafter each referred to as an "EVENT OF WITHDRAWAL"):

                                       20
<PAGE>

                (a)     such General Partner makes an assignment for the benefit
of creditors; files a voluntary petition of bankruptcy; is adjudicated as
bankrupt or insolvent or is the subject of an order for relief under the
bankruptcy laws; files a petition or answer seeking for itself any
reorganization, arrangement or similar relief under any statute, law or
regulation; files an answer or other pleading admitting or failing to contest
the material allegations of a petition filed against it in any proceeding of
this nature; or seeks, consents to or acquiesces in the appointment of a
trustee, receiver or liquidator of all or any substantial part of its
properties;

                (b)     such General Partner fails to dismiss within one hundred
twenty (120) days after the commencement of any proceeding which attempts to
attach or charge the General Partner's Partnership interest or which seeks
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar relief against the General Partner under any statute, law or
regulation, or if within ninety (90) days after a court order attaching or
charging its Partnership interest or the appointment without its consent or
acquiescence of a trustee, receiver or liquidator of such General Partner or all
or any substantial part of its properties, the order or appointment is not
vacated or stayed, or within ninety (90) days after the expiration of any such
stay, the order or appointment is not vacated;

                (c)     In the case of any General Partner which is a
corporation, limited partnership or limited liability company, the filing of a
certificate of dissolution or its equivalent for the corporation, limited
partnership or limited liability company, or the revocation of its charter or
authority to do business in the jurisdiction of its formation;

                (d)     The withdrawal of a General Partner from the Partnership
as provided in Section 8.1 above; or

                (e)     The Transfer by a General Partner of all or any part of
its interest in the Partnership except as approved by Partnership Vote pursuant
to Section 8.1.

                Any person ceasing to be a General Partner (other than as a
result of paragraph (d) and (e) of this Section 8.2) shall automatically become
a limited partner of the Partnership having the same percentage interest in the
profits, losses and distributions of the Partnership that it had while it was a
general partner, and provided further that in the event that the Partners elect
to continue the Partnership pursuant to Section 12.1(b) below, and a new General
Partner is admitted to the Partnership to enable the Partnership to continue,
then the General Partner being converted to a limited partner shall Transfer a
..005% Residual Percentage to the newly admitted general partner. Such Transfer
shall not reduce the interest in the Partnership of any Partner other than the
General Partner which is being converted to a limited partner.

        8.3     GENERAL PROHIBITION AGAINST TRANSFERS OF LIMITED PARTNER'S
INTEREST. A Limited Partner may not Transfer any or all of such Partner's
interest in the Partnership except as permitted in Section 8.4. Any act in
violation of this Article shall be null and void as against the Partnership and
the Partners, except as otherwise provided by law.

        8.4     CONDITIONS UPON TRANSFERS BY A LIMITED PARTNER. A Limited
Partner may Transfer all or any part of such Partner's interest in the
Partnership only with the written consent of the General Partner and Approval by
Partnership Vote; provided, however, that the General Partner's written consent
shall not be given unless:

                        (i)     the General Partner is satisfied that the
proposed Transfer will not have any adverse effect upon the Partnership or the
Partners under federal income tax laws then in effect or cause any default in
any loan documents of the Partnership or the Property owner;

                                       21
<PAGE>

                        (ii)    the General Partner has received, if requested,
an opinion from counsel for the Partnership to the effect that such Transfer
will not violate federal or state securities laws or regulations; and

                        (iii)   the person, firm or entity to acquire such
interest agrees to comply with all terms of this Agreement, including without
limitation Section 8.5 below.

        8.5     SUBSTITUTION OF ASSIGNEE. No Transferee of the whole or any
portion of a Limited Partner's interest in the Partnership shall have the right
to be admitted to the Partnership and become a Limited Partner unless and until
all of the Partners in their absolute discretion consent and all of the
following conditions are satisfied:

                (a)     the Transferor and Transferee execute and acknowledge a
written instrument of assignment, together with such other instruments as the
General Partner may deem necessary or desirable to effect the admission of the
Transferee as a substitute Limited Partner; and

                (b)     an instrument specifically Transferring such interest,
signed by both assignor and assignee, shall be filed with the General Partner,
and until such instrument is so filed, the Partnership shall not recognize any
Transfer of interest for the purposes of making payments of profits, income or
any other distribution with respect to such interest.

        8.6     BUY-SELL IN EVENT OF OFFER TO PURCHASE ASSETS.

                (a)     If a BONA FIDE offer (an "OFFER TO PURCHASE") is made to
the Partnership for the purchase of the then-remaining portion of the Property
still owned by the Partnership, the General Partner shall notify the Partners of
such offer. Within five (5) business days after all the Partners have been
notified of such the Offer to Purchase, each Partner shall send to the other
Partners written notice (the "RESPONSE NOTICE") whether such offer is
acceptable. If one or more Partners desires to accept the Offer to Purchase and
the other Partners do not, then any Partner that wants to accept the Offer to
Purchase (whether one or more, the "SELLING PARTNER") shall have the right,
within five (5) business days after the latest of the Response Notices is
received, to request in writing that the Partners that do not want to accept the
Offer to Purchase (whether one or more, the "PURCHASING PARTNER") purchase the
interest in the Partnership owned by the Selling Partner. In such event, the
Purchasing Partner shall have five (5) business days after receipt of such
notice from the Selling Partner to elect by written notice to the Selling
Partner either (i) to purchase the interest of the Selling Partner, or (ii) to
accept the Offer to Purchase. The failure of a Purchasing Partner to respond to
such notice from the Selling Partner within such five (5) business day period
shall be deemed an election by the Purchasing Partner to purchase the interest
of the Selling Partner as set forth in clause (i) of the preceding sentence. In
the event that the Purchasing Partner elects (or is deemed to have elected) to
purchase the interest of the Selling Partner, the purchase price payable by the
Purchasing Partner to the Selling Partner shall be an amount equal to the amount
which the Selling Partner would have received had the Property been sold by the
Partnership pursuant to the terms of the Offer to Purchase that the Selling
Partner wished to accept. Closing shall occur at the offices of the Partnership
no later than sixty (60) days following the date the Purchasing Partner elects
(or is deemed to have elected) to purchase the Selling Partner's interest in the
Partnership. It is understood and agreed that if a portion of the Assets are
sold between the time that the Purchasing Partner elects (or is deemed to have
elected) to purchase the Selling Partner's interest and such closing, the
proceeds of such sale shall be retained by the Partnership and not distributed
to the Partners.

                (b)     At the closing, the applicable interests in the
Partnership shall be duly conveyed, free of all liens and encumbrances. The
purchase price shall be paid by wire transfer of immediately available federal
funds, unless a different manner of payment was set forth in the offer or is
otherwise

                                       22
<PAGE>

agreed to by the Partnership. At the election of the Purchasing Partner, the
applicable interests in the Partnership to be purchased may be acquired in the
name of a nominee (whether or not such nominee is an Affiliate of the Purchasing
Partner), provided, that the Purchasing Partner shall have designated such
nominee by written notice prior to the date of purchase. It shall be a condition
of the Selling Partner's obligation to proceed with any such purchase that the
Purchasing Partner shall have obtained releases of any guaranties of
indebtedness of the Partnership executed by the Selling Partner or any
Affiliates of (or principals in) the Selling Partner. The Purchasing Partner, in
addition to paying at the closing the purchase price, shall be obligated to loan
to the Partnership an amount sufficient to discharge at the closing all
outstanding and unpaid obligations of the Partnership to the Selling Partner as
of such time.

                (c)     Upon receipt of the purchase price, the Selling Partner
shall execute and deliver all documents reasonably required to transfer the
interest in the Partnership being sold. The Selling Partner shall also execute
such resignations and other documents as may be reasonably required by counsel
for the Partnership to accomplish the withdrawal of the Selling Partner as a
Partner of the Partnership and the Purchasing Partner shall assume all of the
Selling Partner's obligations to the Partnership and any of its creditors under
any loans to the Partnership permitted by this Agreement, such assumptions to be
in form reasonably satisfactory to counsel for the Selling Partner.

                (d)     It is expressly agreed that the remedy at law for breach
of any of the obligations set forth in this Section 8.6 is inadequate in view of
(i) the complexities and uncertainties in measuring the actual damages that
would be sustained by reason of the failure of a Partner to comply fully with
each of said obligations, and (ii) the uniqueness of the Partnership business
and Partners' relationship. Accordingly, each of the aforesaid obligations shall
be, and is hereby expressly made, enforceable by specific performance.

        8.7     BUY-SELL AGREEMENT.

                (a)     Any Partner (the "OFFEROR") may make an offer in writing
to the other Partners (the "OFFEREE"), which shall state an amount (the
"BUY-SELL VALUE") determined in the sole and absolute discretion of the Offeror.
The Buy-Sell Value shall be the amount that the Offeror chooses to be the value
of the Assets. An offer made pursuant to this Section 8.7 shall constitute an
irrevocable offer by the Offeror to the Offeree either (i) to sell all, but not
less than all, of the Offeror's interests in the Partnership (including any
interests held by, or Transferred to, its Affiliates), or (ii) to purchase all,
but not less than all, of the Offeree's interests in the Partnership (including
any interests held by or Transferred to its Affiliates). The Offeree shall have
sixty (60) days after receipt of an offer made pursuant to this Section 8.7 to
elect either (A) to sell its interests in the Partnership at a price equal to
the amount the Offeree would have received pursuant to a liquidation of the
Partnership if the Assets had been sold to a third party for the Buy-Sell Value
and the proceeds therefrom had been applied and distributed in accordance with
Section 12.2 (assuming that all allocations resulting from the sale had been
made and no reserves are established); or (B) to buy the Offeror's interest in
the Partnership at a price equal to the amount the Offeror would have received
pursuant to a liquidation of the Partnership if the Assets had been sold to a
third party for the Buy-Sell Value and the proceeds therefrom had been applied
and distributed in accordance with Section 12.2 (assuming that all allocations
resulting from the sale had been made and no reserves are established). If the
Offeree fails to make such an election within sixty (60) days after receipt of
an offer under this Section 8.7(a), the Offeree shall be deemed to have elected
to sell its interests in the Partnership. In any case in which there is more
than one purchasing Partner, the purchasing Partners shall determine the
proportions of the interests in the Partnership to be purchased by each such
Partner.

                (b)     Closing shall occur at the offices of the Partnership no
later than ninety (90) days following the date after the election to purchase
has been made or deemed made. It is understood and agreed that if a portion of
the Assets are sold between the time that the Offeror initiates the procedure
set

                                       23
<PAGE>

forth Section 8.7(a) above and closing, the proceeds of such sale shall be
retained by the Partnership and not distributed to the Partners. At the closing,
the applicable interests in the Partnership shall be duly conveyed, free of all
liens and encumbrances, and the purchase price shall be paid by wire transfer of
immediately available federal funds. At the election of the purchasing Partner,
the applicable interests in the Partnership to be purchased may be acquired in
the name of a nominee (whether or not such nominee is an Affiliate of the
Purchasing Partner), provided, that the Purchasing Partner shall have designated
such nominee by written notice prior to the date of purchase. It shall be a
condition of the selling Partner's obligation to proceed with any such purchase
that the purchasing Partner shall have obtained releases of any guaranties of
indebtedness of the Partnership executed by the selling Partner or any
Affiliates of (or principals in) such selling Partner. The purchasing Partner,
in addition to paying at the closing the purchase price, shall be obligated to
loan to the Partnership an amount sufficient to discharge at the closing all
outstanding and unpaid obligations of the Partnership to the selling Partner as
of such time.

                (c)     Upon receipt of the purchase price, the selling Partner
shall execute and deliver all documents reasonably required to transfer the
interest in the Partnership being sold. The selling Partner shall also execute
such resignations and other documents as may be reasonably required by counsel
for the Partnership to accomplish the withdrawal of the selling Partner as a
Partner of the Partnership and the purchasing Partner shall assume all of the
selling Partner's obligations to the Partnership and any of its creditors under
any loans to the Partnership permitted by this Agreement, such assumptions to be
in form reasonably satisfactory to counsel for the selling Partner.

                (d)     It is expressly agreed that the remedy at law for breach
of any of the obligations set forth in this Section 8.7 is inadequate in view of
(i) the complexities and uncertainties in measuring the actual damages that
would be sustained by reason of the failure of a Partner to comply fully with
each of said obligations, and (ii) the uniqueness of the Partnership business
and Partners' relationship. Accordingly, each of the aforesaid obligations shall
be, and is hereby expressly made, enforceable by specific performance.

        8.8     AUTHORITY OF GENERAL PARTNER. For purposes of Section 8.6 and
Section 8.7 above, the General Partner and BH Investors shall be treated as one
Partner, and the General Partner shall make all decisions on behalf of the
General Partner and BH Investors regarding the initiation of the buy/sell
procedure or any other decision to be made pursuant to Section 8.6 or Section
8.7. BH Investors hereby irrevocably constitutes and appoints the General
Partner as its attorney-in-fact with full power to bind BH Investors hereunder
and execute documents of transfer on its behalf.

        8.9     COST AND EXPENSE OF TRANSFER; ALLOCATION OF PROFITS AND LOSSES.
All costs and expenses incurred by the Partnership in connection with any
disposition of a Partner's interest, including any filing, recording and
publishing costs and the fees and disbursements of counsel, shall be paid by the
Partner disposing of such interest. If an interest in the Partnership is
disposed of pursuant to this Article VIII, the selling Partner shall
nevertheless be entitled to a portion of the profits and be charged with a
portion of the losses allocated to such interest or part thereof for the fiscal
year of the Partnership in which such disposition occurs, consistent with
Section 7.7 above.

                                  ARTICLE IX.

                        OWNERSHIP OF PARTNERSHIP PROPERTY

        All real or personal property, including all improvements placed or
located thereon, acquired by the Partnership shall be owned by and in the name
of the Partnership, such ownership being subject to the other terms and
provisions of this Agreement.

as shall properly reflect the actions of the Partnership in accordance with
accounting principles generally accepted within the industry and consistently
applied on such basis as will, in the opinion of the Partnership's accountants,

matters partner" of the Partnership as defined in Sections 6221 ET SEQ, of the
Code and, in the event of an audit of the Partnership by the Internal Revenue
Service ("IRS"), the General Partner, at Partnership expense, shall have the

Partners to act on behalf of the Partnership in such negotiations, and each

                                       25

Partner will execute such further authority as the IRS may require to permit the

contemplated by Sections 6222 through 6232 of the Code without prior Approval by
Partnership Vote. This provision is not intended to authorize the General
Partner to take any action left to the determination of an individual Partner
under Sections 6222 through 6232 of the Code.

                                  ARTICLE XI.

        11.1    AUTHORITY TO AMEND. This Agreement may be altered or amended by

        12.1    DISSOLUTION.

                (a)     It is the intention of the Partners that the Partnership

or obligation hereunder by reason of any such dissolution; provided, however,
that the Partnership shall be terminated, its affairs wound up and its property
and assets distributed on the earlier of:

                        (i)     expiration of the Partnership term as provided
in Section 1.5 hereof;

                                       26
<PAGE>

                        (ii)    the written consent of the General Partner and
the Limited Partners holding a Majority in Interest of the Residual Percentages;

                        (iii)   an Event of Withdrawal of a General Partner (as
defined in Article VIII hereof) unless at the time of the Event of Withdrawal,
there is at least one (1) other General Partner or the provisions of Section
12.1(b) below are satisfied;

                        (iv)    the disposition (including condemnation or
casualty loss) of all or substantially all of the property and assets of the
Partnership and receipt of the proceeds from such sale of other disposition
(except under circumstances where (x) all or a portion of the purchase price is
payable after the closing of the sale or other disposition, or (y) the
Partnership retains a material economic or ownership interest in the entity to
which all or substantially all of its assets are Transferred); or

                        (v)     dissolution by law or appropriate judicial
decree.

                (b)     Upon the occurrence of any Event of Withdrawal of a
General Partner at a time when there is no other General Partner, the
Partnership shall be continued if, within a period of ninety (90) days from the
date of such occurrence, all other Partners agree in writing that the
Partnership shall be continued and designate one or more individuals or legal
entities to be admitted to the Partnership as a General Partner, which agreement
shall be effective as of the date of the occurrence of the applicable Event of
Withdrawal. Any such individual or legal entity shall, upon admission to the
Partnership, succeed to all of the rights and powers of a General Partner
hereunder.

                (c)     Dissolution of the Partnership shall be effective on
December 31, 2053 or the day on which the event occurs giving rise to the
dissolution, but the Partnership shall not terminate until the Certificate shall
have been canceled and the assets of the Partnership shall have been distributed
as provided below. Notwithstanding the dissolution of the Partnership, prior to
the termination of the Partnership as aforesaid, the business of the Partnership
and the affairs of the Partners shall continue to be governed by this Agreement.

                (d)     The bankruptcy, insolvency, dissolution, or adjudication
of incompetency of a Limited Partner shall not cause the dissolution of the
Partnership. In the event of the bankruptcy, or incompetency of a Limited
Partner, its administrators or representatives ("Successor") shall have the same
rights that such Limited Partner would have had if it had not become bankrupt,
except that, in the event of bankruptcy, such Successor shall have no right to
participate in the management of the Partnership or vote on any Partnership
matter unless such Successor is admitted to the Partnership as a Limited Partner
pursuant to Section 8.5, and the interest of such Limited Partner in the
Partnership shall, until the termination of the Partnership, otherwise be
subject to the terms, provisions and conditions of this Agreement as if such
Limited Partner had not become bankrupt. In the event of any other withdrawal of
a Limited Partner, the Limited Partner shall only be entitled to Partnership
distributions distributable to it but not actually paid to it prior to such
withdrawal and shall not have any right to have its interest in the Partnership
purchased or paid for.

                (e)     Notwithstanding anything in this Agreement to the
contrary, upon a sale of all or substantially all of the assets of the
Partnership in a single transaction (a "SINGLE SALE TRANSACTION") where all or
any portion of the consideration payable to the Partnership is to be received by
the Partnership more than ninety (90) days after the date on which such Single
Sale Transaction occurs, the Partnership shall continue for purposes of
collecting the deferred payments and making distributions to the Partners. In
such event (i) gain recognized and cash distributed in any year as a result of
such Single Sale Transaction

                                       27
<PAGE>

shall be allocated and distributed among the Partners in the same proportion as
such gain and cash would have been allocated and distributed were the entire
gain resulting from such Single Sale Transaction required to be recognized for
Federal income tax purposes in the year in which such Single Sale Transaction
occurred; and (ii) income attributable to interest on deferred payments shall be
allocated among, and such interest shall be distributed to, the Partners as if
the deferred payment obligations received by the Partnership had been
distributed to the Partners pursuant to Section 6.1.

        12.2    WIND-UP OF AFFAIRS. As expeditiously as possible following the
occurrence of an event giving rise to a termination of the Partnership pursuant
to Section 12.1 above, the General Partner(s) or, if none, all of the Limited
Partners or a liquidator appointed by all of the Limited Partners (the General
Partner, Limited Partners or such liquidator, as the case may be, is referred to
here as the "LIQUIDATOR") shall liquidate the assets of the Partnership, apply
and distribute the proceeds thereof as contemplated by this Agreement and cause
the cancellation of the Certificate. As soon as possible after the dissolution
of the Partnership, a full account of the assets and liabilities of the
Partnership shall be taken, and a statement shall be prepared by the independent
accountants then acting for the Partnership setting forth the assets and
liabilities of the Partnership. A copy of such statement shall be furnished to
each of the Partners within ninety (90) days after such dissolution. Thereafter,
the Liquidator shall wind up the affairs of the Partnership and distribute the
Partnership assets in the following order of priority:

                (a)     to creditors (including Partners who are creditors) in
satisfaction of the liabilities of the Partnership, other than liabilities to
existing and former Partners for distributions from the Partnership;

                (b)     to the establishment of any reserves which the
Liquidator deems reasonably necessary for any contingencies or unforeseen
liabilities or obligations of the Partnership. Such reserves shall be paid over
by the Liquidator to an escrow agent or shall be held by the Liquidator for the
purpose of disbursing such reserves in payment of any of such contingencies. At
the expiration of such period as the Liquidator deems advisable, the balance
thereof shall be distributed in the manner and order provided in this Section;

                (c)     to existing and former Partners in satisfaction of any
liabilities to them, if any, for distributions from the Partnership;

                (d)     to Partners in accordance with Section 6.1 above.

        Notwithstanding anything to the contrary, in the event the Partnership
is "liquidated" within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g)
and an event described in Section 12.1(a) shall have occurred, liquidating
distributions shall be made pursuant to this Section 12.2 by the end of the
taxable year in which the Partnership is liquidated, or, if later, within ninety
(90) days after the date of such liquidation. Distributions pursuant to the
preceding sentence may be made to a trust for the purpose of an orderly
liquidation of the Partnership by the trust in accordance with the Act.

        12.3    COMPLIANCE WITH TREASURY REGULATIONS. It is the intent of the
Partners that the allocations provided in Section 7.1 result in distributions
required pursuant to Section 12.2(d) being in accordance with positive Capital
Accounts as provided for in the Treasury Regulations under Code Section 704(b).
However, if after giving hypothetical effect to the allocations required by
Section 7.1, the Capital Accounts of the Partners are in such ratios or balances
that distributions pursuant to Section 12.2(d) would not be in accordance with
the positive Capital Accounts of the Partners as required by the Treasury
Regulations under Code Section 704(b), such failure shall not affect or alter
the distributions required by Section 12.2(d). Rather, the liquidator will have
the authority to make other allocations of Profits and Losses (or items thereof)
among the Partners which, to the extent possible, will result in the Capital
Accounts of each Partners having a balance prior to distribution equal to the
amount of distributions to be received by such Partners pursuant to Section
12.2(d).

                                       28
<PAGE>

        12.4    NO DEFICIT CAPITAL ACCOUNT OBLIGATION. Notwithstanding anything
else to the contrary in this Agreement, upon a liquidation within the meaning of
Section 1.704-1(b)(2)(ii)(g) of the Regulations, if any Partner has a deficit
Capital Account (after giving effect to all contributions, distributions,
allocations and other Capital Account adjustments for all taxable years,
including the year during which such liquidation occurs), such Partner shall
have no obligation to make any Capital Contribution, and the negative balance of
such Partner's Capital Account shall not be considered a debt owed by such
Partner to the Partnership or to any other Person for any purpose whatsoever.

        12.5    DISTRIBUTION IN KIND. If any assets of the Partnership are to be
distributed in kind, the net fair market value of such assets as of the date of
dissolution shall be determined by independent appraisal or by agreement of the
Partners. Prior to distribution, such assets shall be deemed to have been sold
for their fair market values and the Capital Accounts of the Partners shall be
adjusted pursuant to the terms of this Agreement to reflect the allocation of
gain or loss which would have resulted from such deemed sale.

        12.6    CANCELLATION OF CERTIFICATE. Upon the dissolution and the final
liquidation of the Partnership, there shall be filed for record as provided by
Texas law a Certificate of Cancellation executed by the General Partner.

        12.7    RETURN OF CONTRIBUTION NONRECOURSE TO OTHER PARTNERS. Except as
provided by law or as expressly provided in this Agreement, upon dissolution
each Partner shall look solely to the assets of the Partnership for the return
of its Capital Contribution. If the Partnership property remaining after the
payment or discharge of the debts and liabilities of the Partnership is
insufficient to return the cash contribution of one or more Partners, such
Partner or Partners shall have no recourse against any other Partner.

                                  ARTICLE XIII.

                            MISCELLANEOUS PROVISIONS

an action for partition against the Partnership, and each Partner hereby
irrevocably waives, during the term of the Partnership and during the period of
its liquidation following any dissolution, any right to maintain an action for
partition with respect to any of the assets of the Partnership.

        13.15   TIME OF ESSENCE. TIME IS OF THE ESSENCE in connection with this
Agreement.

        13.16   ALTERNATIVE DISPUTE RESOLUTION. If a dispute, controversy or
claim (whether based upon contract, tort, statute, common law or otherwise)
(collectively a "DISPUTE") arises from or relates directly or indirectly to the
subject matter hereof, and if the Dispute cannot be settled through direct
discussions, the parties hereto shall first endeavor to resolve the Dispute by
participating in a mediation administered by the American Arbitration
Association (the "AAA") under its Commercial Mediation Rules before resorting to
arbitration. Thereafter, any unresolved Dispute shall be resolved among the
parties by binding arbitration administered by the AAA in accordance with its
Commercial Arbitration Rules and judgment on the award rendered by the
arbitrator may be entered in any court having jurisdiction. The arbitration
proceedings shall be conducted in Dallas, Texas on an expedited basis before a
single neutral arbitrator (or multiple arbitrators if called for by the
Commercial Arbitration Rules, with all references herein to the arbitrator to
include multiple arbitrators). Each arbitrator shall be an attorney with
excellent academic and professional credentials, who (a) is a member of the Bar
of the State of Texas, (b) has been actively engaged in the practice of law for
at least fifteen (15) years, and (c) specializes in commercial transactions,
with substantial experience with limited partnerships that own and operate
significant commercial real estate. Attorneys selected as arbitrators need not
have any special experience or training in arbitration proceedings. Any attorney
who serves as an arbitrator shall be compensated at a rate equal to his or her
current regular hourly billing rate. Upon the request of either party, the
arbitrator's award shall include findings of fact and conclusions of law
provided that such findings may be in summary form and the arbitrator shall
render his or her decision based on applicable law. The prevailing party in the
arbitration proceeding shall be entitled to an award of all reasonable
out-of-pocket costs and expenses (including attorneys' and arbitrators' fees)
related to the entire arbitration proceeding. Upon request of either party, the
arbitrator may require that the subject arbitration proceedings be kept
confidential and no party shall disclose or permit the disclosure of any
information produced or disclosed in the arbitration proceedings until the award
is final. A party shall not be prevented from seeking temporary injunctive
relief before a court of competent jurisdiction in an emergency situation, but
responsibility for resolution of the Dispute shall be appropriately transferred
to the arbitrator upon appointment in accordance with the provisions hereof.

        13.17   NOTICE OF INDEMNIFICATION. THE PARTIES TO THIS AGREEMENT HEREBY
ACKNOWLEDGE AND AGREE THAT THIS AGREEMENT CONTAINS CERTAIN INDEMNIFICATION
PROVISIONS PURSUANT TO SECTION 5.2.

                                  ARTICLE XIV.

                          SECURITIES LAW CONSIDERATIONS

        14.1    NO REGISTRATION/RESTRICTION ON SALE. THE PARTNERSHIP INTERESTS
HAVE NOT BEEN REGISTERED WITH THE UNITED STATES SECURITIES AND EXCHANGE
COMMISSION UNDER THE SECURITIES ACT OF 1933, NOR HAVE THEY BEEN REGISTERED WITH
THE SECURITIES COMMISSION OF ANY OTHER APPLICABLE STATE, INCLUDING WITHOUT
LIMITATION THE STATE OF TEXAS. THE PARTNERSHIP INTERESTS MAY BE ACQUIRED FOR
INVESTMENT PURPOSES ONLY AND MAY NOT BE OFFERED FOR SALE, PLEDGED, HYPOTHECATED,
SOLD OR TRANSFERRED EXCEPT IN COMPLIANCE WITH THE TERMS AND CONDITIONS OF THIS
AGREEMENT AND IN A TRANSACTION WHICH IS EITHER EXEMPT FROM REGISTRATION UNDER
SUCH ACTS OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACTS.

        14.2    COMPLIANCE WITH SECURITIES LAWS. The Limited Partners
acknowledge and confirm that their Limited Partnership interests have not been
registered under any federal or state securities laws by

                                       31
<PAGE>

virtue of exemptions from the registration provisions thereof and consequently
cannot be sold except pursuant to appropriate registration or exemption from
registration as applicable. No Transfer of all or any part of a Limited
Partnership interest (except a Transfer upon the death, incapacity or bankruptcy
of a Limited Partner to his personal representative and beneficiaries),
including, without limitation, any Transfer of a right to distributions, profits
and/or losses to a person who does not become a Partner, may be made unless the
Partnership is provided with an opinion of counsel acceptable to the General
Partner (both as to the identity of the counsel and the substance of the
opinion) to the effect that such offer or assignment (a) may be effected without
registration under the Securities Act of 1933, as amended, or the Investment
Company Act of 1940, as amended, and (b) does not violate any applicable federal
or state securities laws (including any investment suitability standards)
applicable to the Partnership or the General Partner.

        14.3    ACCESS TO INFORMATION. Each of the Limited Partners represents
to the General Partner and the Partnership that before determining to enter into
this Agreement and to invest in the Partnership, each Limited Partner made an
independent investigation into the Partnership and the General Partner and that
it received whatever information it deemed necessary or relevant in order to
decide whether to enter into this Agreement or invest in the Partnership. Each
Limited Partner acknowledges that the financial materials provided to the
Limited Partners are only estimates of expected future operations based on
assumptions about future markets and there is no assurance that such projections
will be realized.

        14.4    LIMITATIONS OF FEES. Reference is made to that certain Amended
and Restated Agreement of Limited Partnership of Behringer Harvard Short-Term
Opportunity Fund I LP dated as of September 15, 2003 (together with all
amendments thereto, the "BH FUND AGREEMENT") in respect of BH Fund. BH Fund owns
interests in the General Partner and BH Investors. Notwithstanding anything
contained in this Agreement to the contrary, if any fee paid by the Partnership
to any general partner in BH Fund or any Affiliate of any such general partner
(each a "BH FUND GENERAL PARTNER PARTY") results in BH Fund paying, through its
interest in the Partnership, fees in excess of those fees permitted to be paid
to such BH Fund General Partner Party under the terms of the BH Fund Agreement,
then such BH Fund General Partner Party shall reimburse directly to BH Fund its
allocable share of such fee to the extent necessary to comply with the terms of
the BH Fund Agreement. In the event that a BH Fund General Partner Party
receives from the Partnership a fee whose retention by such BH Fund General
Partner Party is, under the terms of the BH Fund Agreement, contingent upon the
happening of future events, such BH Fund General Partner Party shall hold BH
Fund's allocable share of such fee until the applicable contingencies are
resolved, and shall thereafter dispose of BH Fund's allocable share of such fee
in accordance with the BH Fund Agreement. It is understood and agreed that the
limitations and provisions set forth in this Section 14.4 are for the sole
benefit of BH Fund, and, accordingly, no other party shall be entitled to a
refund of fees paid by the Partnership under this Agreement or any other benefit
set forth in this Section 14.4. Furthermore, it is understood and agreed that
the limitations and other provisions set forth in this Section 14.4 shall not be
applicable at such time as BH Fund no longer owns a direct or indirect interest
in the Partnership.

        14.5    AMENDMENTS TO AGREEMENT. Notwithstanding anything contained
herein to the contrary, in the event that legal counsel for BH Fund reasonably
determines that an amendment to this Agreement is necessary or advisable in
order for this Agreement to comply with applicable securities laws, the BH Fund
Agreement, or NASAA Guidelines (as such term is defined in the BH Fund
Agreement), then each Partner shall, within ten (10) days after request from BH
Fund, execute such an amendment; provided, however, that no such amendment may
reduce a Partner's economic interest in the Partnership or increase a Partner's
liabilities or obligations under this Agreement without such Partner's prior
written consent.

                                    Exhibit D

                                Dilution Example

For purposes of example, assume that the Capital Contributions made to the
Partnership total $2,000,000. General Partner (owning a residual percentage of
..1%) has contributed $2,000; Limited Partner A (owning a residual percentage of
69.9%) has contributed $1,398,000; and Limited Partner B (owning a residual
percentage of 30%) has contributed $600,000. Assume that the General Partner
sends an Additional Capital Notice for $400,000 to the Partners, and that in
response thereto the General Partner makes an Additional Capital Contribution of
$400, Limited Partner A makes an Additional Capital Contribution of $279,600,
and Limited Partner B fails to make its Additional Capital Contribution of
$120,000. If Limited Partner A contributes said $120,000 as an Additional
Capital Contribution (thus making the total Capital Contributions equal
$2,400,000), then the following adjustments to the Residual Percentages would be
made:

        (1)     The Residual Percentage of Limited Partner A would be increased
by 6.25% (being 125% of 5%, which is $120,000 divided by $2,400,000, expressed
as a percentage). The Residual Percentage of Limited Partner A would thus be
adjusted to 76.15%.

        (2)     The Residual Percentage of Limited Partner B would be decreased
by 6.25%, and thus would be adjusted to 23.75%.

        (3)     The increase in the Residual Percentage of Limited Partner A and
the decrease in the Residual Percentage of Limited Partner B would remain
applicable after any scheduled adjustment in the Residual Percentages of such
Partners. For example, if it was originally contemplated that Limited Partner A
and Limited Partner B would have their Residual Percentages adjusted to 49.9%
and 50%, respectively, at such time as the Partners had received the return of
their Capital Contributions, then, based upon the adjustments set forth in
clauses (1) and (2) above, upon the return of such Capital Contributions the
Residual Percentage of Limited Partner A would be 56.15% and the Residual
Percentage of Limited Partner B would be 43.75%.
