                        PURCHASE PRICE AND EARNEST MONEY

        2.1     The purchase price (the "PURCHASE PRICE") for the Property is
Nineteen Million One Hundred Seventy-Four Thousand Nine Hundred and No/100
Dollars ($19,174,900.00). The Purchase Price shall be payable in the manner set
forth in Article III below.

        2.2     Earnest Money (herein so called) in the amount of Seventeen
Thousand Nine Hundred Thirty-Five and No/100 Dollars ($17,935.00.) has
heretofore been deposited in escrow with Heritage Title Company, Austin, Texas
(the "Escrow Agent") by Purchaser, which Earnest Money shall be applied at
Closing (hereinafter defined) to the Purchase Price in the manner provided in
Article III below or otherwise disbursed to either Seller or Purchaser in
accordance with the terms of this Agreement. In the event Purchaser has not
theretofore terminated this Agreement, additional Earnest Money in the amount of
Eighty-Nine Thousand Six Hundred Seventy-Five and No/100 Dollars ($89,675.00)
shall be deposited in escrow with Escrow Agent within two (2) business days
after the expiration of the Inspection Period (hereinafter defined), at which
time such additional Earnest Money shall be, for all purposes, "Earnest Money"
hereunder. All Earnest Money deposited pursuant hereto shall be placed by the
Escrow Agent in an interest bearing account pursuant to the

                                     - 2 -
<PAGE>

written direction of Purchaser, with all interest accruing thereon being for the
sole account of, and payable to, Purchaser in all events, free of and from any
and all claims by Seller, the Escrow Agent or any third party, and Purchaser may
withdraw such interest at any time, and from time to time, as it may elect.
Simultaneously with the execution of this Agreement by all parties hereto,
Purchaser shall also deliver to Seller the sum of One Hundred and No/100 Dollars
($100.00) in cash ("CONTRACT CONSIDERATION"), which Seller acknowledges is
adequate consideration for Seller entering into this Agreement, and which Seller
shall, in all events, retain. Such Contract Consideration shall not be applied
against the cash payment due at the Closing.

        2.3     Purchaser and Seller acknowledge that the Purchase Price is
based in part on the projected revenue of the Property based upon the current
rent roll for the Property. Purchaser and Seller agree to negotiate in good
faith to agree on a fair and equitable increase or decrease in the Purchase
Price in the event that the projected revenue of the Property increases or
decreases between the effective date of this Agreement and that date which is
seven (7) days prior to the Closing Date.

        2.4     In the event of any termination of this Agreement prior to or on
December 15, 2004 which results in a portion of the Earnest Money being
delivered to Seller, Seller agrees that such portion of the Earnest Money owing
to Seller shall be applied by Seller to the purchase price(s) payable by
Purchaser under any of the Other Agreements which are closed and consummated.

                                   ARTICLE III
                            PAYMENT OF PURCHASE PRICE

        3.1     Subject to the terms and provisions hereof, the Purchase Price
shall be payable at Closing by Purchaser as follows:

                3.1.1   By Purchaser taking title to the Property assuming
        (subject to the non-recourse provisions thereof) Seller's existing
        permanent financing on the Property (the "EXISTING FINANCING"). Seller
        shall cooperate with and assist Purchaser in connection with the seeking
        of written approval, upon terms and conditions reasonably acceptable to
        Purchaser, from the holder of the Existing Financing (the "LENDER") for
        Purchaser's assumption (subject to the non-recourse provisions thereof)
        of the Existing Financing, and such written approval shall be a
        condition precedent to Purchaser's obligations hereunder. In the event
        that, as part of the assumption of the Existing Financing by Purchaser,
        Lender refuses to release Seller and Seller's guarantor of the Existing
        Financing from liability under the loan which arises from and after the
        Closing Date, then Seller may, at its option, terminate this Agreement
        by written notice thereof to Purchaser on or before that date which is
        seven (7) days prior to the Closing Date, whereupon all Earnest Money
        shall be immediately returned to Purchaser.

                3.1.2   By Purchaser paying cash, by wire transfer, cashier's or
        certified check or other evidence of funds acceptable to the Title
        Company for disbursement to Seller at Closing, the amount of the
        Purchase Price, less the total amount of unpaid principal and

                                     - 3 -
<PAGE>

        accrued but unpaid interest owing pursuant to the Existing Financing as
        of the Closing Date, subject to prorations and other credits provided
        for in this Agreement.

        3.2     The Earnest Money and Contract Consideration, and all accrued
interest thereon, shall be applied at Closing to the cash payment due on such
date in accordance with Subsection 3.1.1 above or otherwise disbursed to Seller
or Purchaser in accordance with the terms of this Agreement.

                                   ARTICLE IV
                                TITLE AND SURVEY

        4.1     Seller, at the Seller's sole cost and expense, shall cause to be
delivered to Purchaser an ALTA Commitment for Title Insurance for the Property
(the "TITLE COMMITMENT") to be issued by First American Title Insurance Company
("Title Company") through its agent, Ausley & McMullen, P.A., whose address is
227 South Calhoun Street, Tallahassee, Florida 32301 (Attention: M. Julian
Proctor, Jr.), which Title Commitment contemplates the issuance of an ALTA
Owner's Policy of Title Insurance (the "OWNER'S POLICY"). Purchaser acknowledges
receipt of the Title Commitment.

        4.2     Seller, at Seller's sole cost and expense, shall cause to be
delivered to Purchaser search reports (the "SEARCH REPORTS") showing all Uniform
Commercial Code filings covering the Property in both the Office of the
Secretary of State of the State of Florida and in the official records of the
County in which the Land is located. The Search Reports shall be delivered no
later than October 12, 2004.

        4.3     Seller, at Seller's sole cost and expense, has furnished to
Purchaser copies of the most recent survey of the Land and Improvements
(collectively, the "SURVEY") in Seller's possession or control. Purchaser
acknowledges receipt of the Survey.

        4.4     Purchaser shall have until the later to occur of: (i) ten (10)
business days following the last to occur of receipt by Purchaser of the Title
Commitment and true, correct and legible copies of all instruments and documents
referenced as exceptions therein, the Search Reports, and the Survey; or (ii)
the expiration of the Inspection Period (hereinafter defined), to review the
Title Commitment, Search Reports, and Survey ("REVIEW PERIOD"). In the event any
exceptions to title appear in the Title Commitment, or any Uniform Commercial
Code filings exist, or any matters appear in the Survey, that are unacceptable
to Purchaser, Purchaser shall, within said Review Period, notify Seller in
writing of such fact. Upon the expiration of the Review Period, Purchaser shall
be deemed to have accepted all exceptions to title referenced in the Title
Commitment, all Uniform Commercial Code filings referenced in the Search
Reports, and all matters shown on the Survey except for matters which are the
subject of a notification permitted under the following sentence, and such
accepted exceptions shall be included in the term "Permitted Exceptions" as used
herein. In the event that Purchaser does object to any title exceptions or
matters shown in the Title Commitment and/or the Search Reports and/or the
Survey within the Review Period, Seller shall have ten (10) days from receipt of
notice of such objections ("CURE PERIOD") within which to eliminate or modify
any such unacceptable exceptions or items to the reasonable satisfaction of
Purchaser. Seller shall

                                     - 4 -
<PAGE>

use its reasonable efforts in an attempt to so eliminate any such unacceptable
exceptions or items in order to so eliminate or modify such unacceptable items.
In the event that Seller is unable to eliminate or modify such unacceptable
items to the satisfaction of Purchaser on or before the expiration of said Cure
Period, Seller shall notify Purchaser in writing of such fact within said Cure
Period. In such event, Purchaser shall, on or before the Closing, either (a)
waive such objections and accept title to the Property subject to such
unacceptable items (which items shall then be deemed to constitute part of the
"PERMITTED EXCEPTIONS"), or (b) terminate this Agreement by written notice to
Seller and receive an immediate refund of the Earnest Money, plus all accrued
interest thereon, whereupon this Agreement shall automatically be rendered null
and void and of no further force and effect. Notwithstanding anything set forth
herein to the contrary, other than with respect to the Existing Financing, any
liens, mortgages, deeds of trust or security interests affecting any portion of
the Property shall not be Permitted Exceptions hereunder, and same shall be
paid, satisfied and released by Seller at or prior to Closing.

        4.5     Should any exceptions to title first arise or be first
discovered following the Review Period, but prior to Closing, Purchaser shall
have the same right of review as described in Section 4.4 hereinabove as to such
new, additional or different items or matters, except that such review period
shall be for a period expiring on the date that is ten (10) days following the
date Purchaser first becomes aware of such new additional or different items,
and if such date is on or after the Closing Date, the Closing Date shall
automatically be extended so that the Closing Date is the first business day
after the tenth (10th) day of such ten (10) day period.

reason in Purchaser's sole discretion, judgment and opinion, disapprove or be
dissatisfied with any aspect of the Land, the Improvements or any item examined

terminated this Agreement pursuant to this Section 7.2 as of the expiration of
the Inspection Period and the Earnest Money previously deposited by Purchaser
with Escrow Agent shall be immediately returned by Escrow Agent to Purchaser,
whereupon this Agreement shall automatically be terminated and thereafter
neither Seller nor Purchaser shall have any further obligations or liabilities
to the other hereunder except as otherwise provided herein.

terminate this Agreement by written notice thereof to Seller if Lender advises
Purchaser that Purchaser's

                                     - 8 -

        8.1     The closing of the transaction contemplated herein (the
"CLOSING") shall be held on or before that date (the "CLOSING DATE") which is
the earlier to occur of (1) December 15, 2004 (the "OUTSIDE CLOSING Date") and
(2) the later to occur of (a) that date which is ten (10) days after the date on
which Purchaser notifies Seller in writing (a "CLOSING NOTICE") that (i) the
Assumption Documents and the "Assumption Documents" under each of the Other
Agreements (hereinafter defined) are in final form and agreed to by Purchaser,
Lender and the "Lender" under each of the Other Agreements and (ii) all other
conditions of the Lender and the "Lender" under each of the Other Agreements to
the assumption by Purchaser of the Existing Financing and the assumption by
Purchaser of the "Existing Financing" under each of the Other Agreements have

Saturday, Sunday or banking holiday, the Closing shall be the

                                     - 9 -

next regular business day. The Closing shall be held through escrow at the
office of the Title Company's agent, Ausley and McMullen, P.A., or at such other
location as may be acceptable to both Seller and Purchaser.

        Notwithstanding the foregoing, in the event that each of the conditions
set forth in Section 8.1(2)(a) hereinabove have not been satisfied on or before
December 15, 2004, then Purchaser may, at its option, extend the Outside Closing
Date to January 17, 2005 by written notice thereof to Seller; and if Purchaser
does not so extend the Closing Date, then this Agreement shall thereupon
automatically terminate, fifty percent (50%) of the Earnest Money shall be
returned to Purchaser and fifty percent (50%) of the Earnest Money shall be
delivered to Seller and, thereafter, neither Seller nor Purchaser shall have any
further duties or obligations hereunder. In addition, in the event that
Purchaser extends the Outside Closing Date to January 17, 2005 as provided in
the immediately preceding sentence, and each of the conditions set forth in
Section 8.1(2)(a) hereinabove have not been satisfied on or before January 17,
2005, then Purchaser may, at its option, extend the Outside Closing Date to
February 15, 2005 by written notice thereof to Seller; and if Purchaser does not
so extend the Closing Date, then this Agreement shall thereupon automatically
terminate, twenty-five percent (25%) of the Earnest Money shall be returned to
Purchaser and seventy-five percent (75%) of the Earnest Money shall be delivered
to Seller and, thereafter, neither Seller nor Purchaser shall have any further
duties or obligations hereunder.

        Notwithstanding anything set forth herein to the contrary, in the event
that each of the conditions set forth in Section 8.1(2)(a) hereinabove have not
been satisfied on or before February 15, 2005 , then this Agreement shall
thereupon automatically terminate, the Earnest Money shall be delivered to
Seller and, thereafter, neither Seller nor Purchaser shall have any further
duties or obligations hereunder. At such time as Purchaser delivers to Seller a
Closing Notice, Purchaser will be deemed to have waived the conditions set forth
in Sections 8.6.3 and 8.6.4 hereof.

        Notwithstanding the foregoing, if the Closing Date, as hereinabove
determined, would occur after December 15, 2004 and on or before January 4,
2005, then the Closing Date shall automatically be extended so that the Closing
Date will be on January 5, 2005.

transaction contemplated herein, that:

                9.2.1   There are no actions, suits, litigation or proceedings

        board, bureau, agency or instrumentality, domestic or foreign;

                9.2.2   Seller has not received any notices of any condemnation

                9.2.3   Except as to the Permitted Exceptions, there are no
        liens or security interests against the Land, the Improvements or
        against any other portion of the Property, nor are there any actions
        pending which would result in the creation of any lien for any
        Improvements, and Seller shall not create or voluntarily permit to be
        created any liens, easements or other conditions affecting any portion
        of the Property without the prior written consent of Purchaser. At the
        Closing, there will be no unpaid bills or claims in connection with any
        construction or repair of the Improvements or other work performed or
        material purchased in connection with the Improvements;

                9.2.4   No portion of the Property shall be subject at the
        Closing to the burdens or obligations of any management or leasing

        shall receive the Property free and clear of any such burdens or
        obligations and shall be free to enter into a management agreement or
        arrangement with a manager of its own choice. As of the Closing, there
        will not be any service, supply or maintenance agreements with respect

        Purchaser at Closing, shall be terminated by Seller at or prior to
        Closing, and Seller shall indemnify and hold Purchaser harmless of and
        from any and all claims, demands and actions by such employees;

                9.2.5   Seller has all requisite corporate or company power and

        Authorities is required in order for Seller to consummate this
        Agreement;

                9.2.6   To the best of Seller's knowledge, the Land is, and on
        the Closing Date will be, zoned by Applicable Laws which shall permit
        the existence of the current Improvements on the Land, the current
        operation of the existing Improvements thereon and the use by the
        tenants thereof, and except for such zoning, there are no governmental
        or private regulations, orders, agreements or instruments restricting
        the current use and operation of the Land as currently used except as

        Section 4.1 hereof;

                9.2.7   This Agreement is a valid obligation of Seller and is
        binding upon and enforceable against Seller in accordance with its
        terms;

                9.2.8   The consummation by Seller of the transactions
        contemplated hereby do not, and at the Closing Date will not, constitute
        a violation of any order, rule or regulation applicable to Seller or any
        portion of the Property of any court or of any federal or state or
        municipal regulatory body or administrative agency or other governmental
        body having jurisdiction over Seller or any portion of the Property;

                9.2.9   Seller is the owner of good and marketable fee simple
        title to the Property, free and clear of any liens, deeds of trust,
        pledges, security interests, leases, charges, encumbrances or
        restrictions of any kind, except as will be shown in the Title
        Commitment to be provided in accordance with Article IV hereof;

                9.2.10  Seller is not in default under any indenture, mortgage,
        deed of trust or loan agreement or under any other restrictions,
        covenants or agreements to which it is a party or by which it is bound
        and which in any way affects the Property. Seller is not a party to, nor
        bound by, any agreement or any order or decree of any court or
        governmental agency which might to a material degree adversely affect
        any portion of the Property;

                9.2.11  To the best of Seller's knowledge, at Closing, the
        existing water, sewer, gas and electricity lines, storm sewer and other
        utility systems on the Land as of the date hereof will not be impaired
        or reduced. To the best of Seller's knowledge, all existing utilities
        enter the Land through adjoining public streets or private land in
        accordance with valid public or private easements that will inure to the
        benefit of Purchaser and its successors and assigns. To the best of
        Seller's knowledge, all of said utilities have been fully installed and
        are operating, with all installation and connection charges paid in
        full, and the right to the return of any deposit made in connection
        therewith shall inure to the benefit of Seller;

                9.2.12  Seller has paid all taxes, charges and assessments
        (special or otherwise) required to be paid to any taxing authority which
        could in any way now or hereafter constitute a lien against the Property
        or any part thereof (except for taxes and assessments for the current
        year). Seller has not received any notice from any taxing authority or

                                     - 19 -

        governmental agency asserting that Seller has failed to file or has
        improperly filed any tax return or report required to be filed by it, or
        that it has not paid all taxes, charges or assessments now owing by it
        (except current taxes and assessments not yet delinquent) which could in
        any way now or hereafter constitute a lien against the Property or any
        part thereof; and no action or proceeding is now pending by a
        governmental agency or authority for the assessment or collection of
        such taxes, charges or assessments against Seller. To the best of
        Seller's knowledge, the Property is not the subject of any taxes,
        assessments, fees of any type or kind relating to the imposition of any
        roadway, utility or other district created or assessed by the State of

        the municipality in which the Property is located, and Seller has not
        received any notice of any such taxes, assessments or fees;

                9.2.13  With regard to Seller's schedules (including cash flow
        reports and financial data, operating expenses, property facts, mortgage
        information and lease characteristics) and other financial reports,
        financial statement and other information relating to the Property which
        have been or are to be furnished to Purchaser, to the best of Seller's
        knowledge, the same are true and correct and Seller has not
        intentionally misrepresented the information shown thereby, and to the
        best of Seller's knowledge there are no materially misleading or
        inaccurate items or information shown thereby or contained therein;

                9.2.14  Seller has not received any notices from any insurance
        company of any defects or inadequacies in the Property or any part
        thereof which would adversely affect the insurability of the Property or
        the premiums for the insurance thereof;

                9.2.15  The copies of the Tenant Leases to be delivered to
        Purchaser in accordance with the terms of this Agreement (and to be
        assigned at Closing) are and shall be true and correct and constitute
        all of the leases affecting the Property, and no tenants are or shall be
        entitled to any rebates, allowances, rent concessions or free rent for
        any period subsequent to the Closing without the prior written consent
        of Purchaser; all obligations and items of an inducement nature to be
        performed by the landlord under the Tenant Leases have been fully
        performed and no commitments have been made to any tenant for repairs or
        improvements other than a general landlord requirement for normal
        maintenance in the future; other than in connection with the Existing
        Financing, no rents due under any of said leases have been assigned,
        hypothecated or encumbered; no Tenant Leases shall be further modified
        or amended without the prior written consent of Purchaser; no tenant has
        any purchase option, right of first refusal, or other interest (other
        than its leasehold tenancy for a specified term as stated in its lease);
        no tenant has given Seller notice of its intention to vacate its leased
        premises prior to the end of the primary term (or any current renewal or
        extended term); all of the Tenant Leases are in full force and effect
        without current default by either Seller or the respective tenants;
        there are no pending claims asserted by any tenants for offsets against
        rent or any other claims (whether monetary or otherwise) made against
        Seller as landlord under the Tenant Leases; and there are no fees or
        commissions payable to any person or entity in regard to the Tenant
        Leases or the Property except as specifically set forth herein;

        have been obtained on all operations to date and shall be maintained
        through Closing;

                9.2.17  Seller has not received any notice of any violation of
        any, and to the best of Seller's knowledge it has complied with each,

        and use of the Improvements do not and will not violate any applicable
        law, statute, ordinance, rule, regulation, policy, order or
        determination of any federal, state, local or other governmental
        authority ("GOVERNMENTAL AUTHORITY" or "GOVERNMENTAL AUTHORITIES") or
        any board of fire underwriters (or other body exercising similar
        functions), or any restrictive covenant or deed restriction affecting
        any portion of the Property, including without limitation, any
        applicable zoning ordinances and building codes, ADA, flood disaster
        laws, and health and environmental laws, rules and regulations
        (hereinafter collectively called the "APPLICABLE LAWS");

                9.2.18  To the best of Seller's knowledge, neither the Property
        or Seller are the subject of any pending or threatened investigation or
        inquiry by any Governmental Authority, or are subject to any remedial
        obligations under any Applicable Laws pertaining to health or the
        environment ("APPLICABLE ENVIRONMENTAL LAWS"), including, without
        limitation, the Comprehensive Environmental Response, Compensation, and
        Liability Act of 1980, as amended ("CERCLA"), the Resource Conservation
        and Recovery Act of 1987, as amended ("RCRA"), and this representation
        and warranty would continue to be true and correct following disclosure
        to any applicable Governmental Authority of all relevant facts,
        conditions, and circumstances pertaining to the Property and/or Seller;

                9.2.19  To the best of Seller's knowledge, the use which Seller
        makes of the Property does not result in the disposal or release of any
        hazardous substance, solid waste or other substance known or suspected
        to pose a threat to health or the environment ("HAZARD") on, in or to
        the Property. The terms "hazardous substance" and "release" shall each
        have the meanings specified in CERCLA, and the terms "solid waste" and
        "disposal" (or "disposed") shall each have the meanings specified in
        RCRA;

                9.2.20  Intentionally Omitted;

                9.2.21  Neither Seller nor, to the best of Seller's knowledge
        and belief, any tenant of any portion of the Property, has received any
        notice from any Governmental Authority with respect to any violation of
        any Applicable Laws;

                9.2.22  To the best of Seller's knowledge, the Submission
        Materials delivered to Purchaser hereunder are all of the agreements
        affecting the Property and none of the Submission Materials or other

                9.2.23  Neither Seller nor, to Seller's knowledge, Lender, is in
        default under any Existing Financing Documents. The Existing Financing
        is not "cross-collateralized" or "cross-defaulted" with any other
        indebtedness. The Schedule delivered by Seller to Purchaser pursuant to
        Section 5.1.18 is true and correct as of the date it is delivered to
        Purchaser; and

                9.2.24  Seller is not in default under any other agreements to
        which it is a party or by which it is bound and which in any way affects
        the Property.

        9.3     Seller acknowledges and agrees that Purchaser has and will rely
upon the covenants, agreements, representations, and warranties set forth in
this Agreement in purchasing the Property and that said covenants, agreements,
representations, and warranties are essential conditions but for which Purchaser
would not acquire the Property. The covenants, agreements, representations, and
warranties herein contained shall be binding upon Seller, its successors,
assigns, and legal representatives, shall inure to the benefit of Purchaser, its
successors, assigns and legal representatives, and shall survive the Closing of
the sale and purchase of the Property for a period of one (1) year thereafter.

        9.4     Purchaser hereby represents and warrants to Seller as follows:

                9.4.1   Purchaser is a limited liability company duly authorized
        and validly existing under the laws of the State of Delaware;

                9.4.2   Purchaser has or will have the power and authority to
        enter into this Agreement and deliver the Purchase Price and other items
        called for upon Closing, and the party signing this Agreement on behalf
        of Purchaser has the power and authority to sign this Agreement on
        behalf of Purchaser; and

                9.4.3   Neither the execution nor delivery of this Agreement by
        Purchaser will result in a violation or breach of any term or provision
        or constitute a default under any agreement to which Purchaser is a
        party.

        9.5     In the event that either party should discover prior to the
Closing Date that any representation or warranty made by it is untrue or
inaccurate, it shall promptly inform the other party in writing of its
discovery. Each party's obligation to consummate this transaction is expressly
conditioned (which condition may be waived by the party to whose benefit the
representation or warranty is made) upon the lack of any material variance with
respect to the truth and accuracy of all warranties and representations as of
the Closing Date which are made by the other party. If any of Seller's
representations and warranties are untrue or inaccurate, and Purchaser elects to
terminate this Agreement because of same, Purchaser shall be entitled to a
refund of the Earnest Money, plus all accrued interest thereon.

necessary in order to complete the transaction herein provided and to carry out
the intent and purposes of this Agreement.

                                   ARTICLE XI
                                   COMMISSIONS

        11.1    Seller and Purchaser hereby agree and acknowledge that Smith
Equities Corporation, representing Seller (the "AGENT") is the sole agent,
finder, broker or advisor in regard to the transaction contemplated by this
Agreement and if, as and when the transaction contemplated hereby is fully
closed, consummated and recorded, Seller shall pay a commission to Agent
pursuant to a separate written agreement between Seller and Agent. Each party
hereto represents to the other that, except as set forth above with respect to
the Agent, it has not authorized any broker or finder to act on its behalf in
connection with the sale and purchase hereunder and that it has not dealt with
any broker or finder purporting to act for any other party.

        11.2    Each party hereto agrees to indemnify and hold harmless the
other party from and against any and all liabilities, costs, damages and
expenses of any 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 this Agreement insofar as such claims shall be based
upon alleged arrangements or agreements made by such party or on its behalf.

                                   ARTICLE XII
                        TERMINATION, DEFAULT AND REMEDIES

        12.1    If this Agreement is terminated because of a failure of one or
more of the covenants, conditions or agreements contained in this Agreement, or
because of any specific right of Purchaser to terminate this Agreement,
including without limitation those termination rights contained in Article IV,
Article V, Article VII, Article VIII, Article IX or Article XIII hereof
(hereinafter referred to as a "PERMITTED Termination"), the Earnest Money, and
all accrued interest thereon, shall be immediately returned to Purchaser,
whereupon neither party shall have any further rights or obligations hereunder.

        12.2    In the event that any of the Seller's representations or
warranties contained herein are untrue or if Seller shall have failed to have
performed any of the covenants and/or agreements contained herein which are to
be performed by Seller, Purchaser may, at its option and as its sole remedy
either (a) terminate this Agreement by giving written notice of termination to
Seller and Escrow Agent and receive a full and immediate refund of any and all
Earnest Money and accrued

                                     - 23 -
<PAGE>

interest thereon; or (b) seek to enforce specific performance of this Agreement.
Nothing herein shall be deemed to limit Purchaser's remedies in the event of a
breach of any representation or warranty by Seller following the Closing.

        12.3    If Purchaser fails to close the transaction contemplated hereby
for any reason other than a Permitted Termination, Seller shall be entitled to
receive the Earnest Money as liquidated damages as Seller's sole and exclusive
remedy for such failure, Seller hereby specifically waiving any and all rights
which it may have to damages or specific performance as a result of Purchaser's
default under this Agreement. SELLER AND PURCHASER AGREE THAT IT WOULD BE
IMPRACTICAL AND EXTREMELY DIFFICULT TO ESTIMATE THE DAMAGES WHICH SELLER WOULD
SUFFER IF THE PURCHASE AND SALE CONTEMPLATED BY THIS AGREEMENT IS NOT
CONSUMMATED BY REASON OF PURCHASER'S FAILURE TO PERFORM ITS OBLIGATIONS UNDER
THIS AGREEMENT. SELLER AND PURCHASER FURTHER AGREE THAT THE EARNEST MONEY
CONSTITUTES A FAIR AND REASONABLE ESTIMATE OF THE TOTAL DETRIMENT WHICH SELLER
WOULD SUFFER IN THE EVENT OF SUCH A DEFAULT BY PURCHASER.

                                  ARTICLE XIII
                                  RISK OF LOSS

        Risk of all loss, destruction, or damage to the Property, or any portion
thereof, from any and all causes whatsoever until consummation of the Closing
shall be borne by Seller. In the event that any portion of the Improvements,
Personal Property, or the Land are damaged by fire or other casualty, or all or
any portion of the Land or Improvements is condemned or taken by eminent domain
by any competent authority for any public or quasi-public use or purpose, or
preliminary steps in such condemnation for eminent domain proceedings shall have
been taken before the Closing Date, Seller shall give immediate notice thereof
to Purchaser. In the event that any such casualty or condemnation (or threat
thereof) does or could result in damages costing more than an amount equal to
five percent (5%) of the Purchase Price to repair or replace, or have an adverse
effect on the access to or use of the Property (a "Material Casualty or
Condemnation"), Purchaser, at its option, may terminate this Agreement by
written notice to Seller prior to or at the Closing, in which event the Earnest
Money shall be returned to Purchaser and, thereafter, neither Seller nor
Purchaser shall have any further duties or obligations hereunder. In the event
that (i) such casualty or condemnation (or threat thereof) is not a Material
Casualty or Condemnation, or (ii) such casualty or condemnation (or threat
thereof) is a Material Casualty or Condemnation, but Purchaser elects not to
terminate this Agreement as aforesaid, then the Closing shall take place as
provided herein without abatement of the Purchase Price, and Seller shall assign
to Purchaser at Closing all of the rights and interests of Seller in and to any
insurance proceeds or condemnation awards which may be paid or payable to Seller
on account of any such occurrence; provided, however, that Seller shall pay to
Purchaser in cash at Closing the amount of any deductible under any existing
insurance policies applicable to such occurrence.

to be given to either party hereunder, except those required to be delivered at

agreement between the parties, and no promise, representation, warranty, or
covenant not included in this Agreement or any such referenced agreements has
been or is relied upon by either party. Each party has relied upon its own

its own advisors, and the warranties, representations, covenants, and agreements
expressly contained in this Agreement. No modification or amendment of this
Agreement shall be of any force or effect unless made in writing and executed by
both Purchaser and Seller. In the event that any litigation arises hereunder, it
is specifically stipulated that this Agreement shall be interpreted and
construed according to the laws of the State of Florida. Further, the prevailing

                                  MISCELLANEOUS

        16.1    The article headings contained in this Agreement are for
purposes of identification only and shall not be considered in construing this
Agreement.

        16.2    This Agreement, and the rights and obligations of Purchaser
hereunder, may be assigned by Purchaser to any related party or affiliate of
Purchaser at any time prior to Closing. In the event of any such assignment, the
original party designated as the Purchaser shall be released from all duties and
obligations hereunder and Seller agrees to close the transaction contemplated
hereunder with the assignee of Purchaser. This Agreement may not be assigned by
Seller.

        16.3    All references in this Agreement to "the date hereof" or similar
references shall be deemed to refer to the last date, in point of time, on which
all parties hereto have executed and received a fully executed copy of this
Agreement. This Agreement constitutes an offer by Purchaser to purchase the
Property on the terms and conditions and for the Purchase Price specified
herein. Unless sooner terminated or withdrawn by notice in writing to Seller,
this offer shall automatically lapse and terminate at 5:00 p.m. Central Time on
September 23, 2004, unless, prior to such time, Seller has returned to Escrow
Agent two (2) fully executed copies of this Agreement.

        16.4    Words of any gender used in this Agreement shall be held and
construed to include any other gender, and words of a singular number shall be
held to include the plural and vice versa, unless the context requires
otherwise.

        16.5    This Agreement may be executed in any number of counterparts,
each of which shall be an original, but such counterparts together shall
constitute one and the same instrument.

        16.6    All exhibits described in this Agreement are by this reference
fully incorporated herein and made a part hereof by reference for all purposes.

        16.7    This Agreement and the terms and provisions hereof shall inure
to the benefit of and be binding upon the parties hereto and their respective
heirs, executors, personal representatives, successors and assigns whenever the
context so requires or admits.

        16.8    Title Company hereby agrees to (a) timely file a return with the
Internal Revenue Service on Form 1099-B or such other form as instructed by the
Internal Revenue Service showing

                                     - 26 -
<PAGE>

the gross proceeds of this transaction, the recipient thereof and such other
information as the Internal Revenue Service may by form or regulation require
from time to time, and (b) furnish both Seller and Purchaser with a written
statement showing the name and address of the Title Company and the information
shown on such return with respect to the transaction. This return shall be filed
to ensure that the parties to this transaction will be in compliance with
Section 6045(e) of the Internal Revenue Code, as amended from time to time and
as further set forth in any regulations promulgated thereunder.

        16.9    Neither Seller nor Purchaser shall, without the written consent
of the other, publicize this Agreement or the sale contemplated by this
Agreement. All news and press releases, advertisements, and other public
dissemination concerning this Agreement or the sale contemplated by this
Agreement shall be jointly coordinated by Seller and Purchaser and shall be
subject to both Seller's and Purchaser's written approval. Seller shall not
disclose to any third party (other than Seller's lender, employees, agents,
attorneys, investors and brokers, all of which shall be advised of the
requirements of this Section 16.9) the terms of this Agreement, including
without limitation the Purchase Price, and such agreement on the part of Seller
shall survive the Closing Date and shall not merge into the closing of this
transaction. Notwithstanding the foregoing, this Article shall not be deemed to
prevent the disclosure following the Closing of information which is readily
available to the public at large.

        16.10   Notwithstanding anything set forth or implied herein to the
contrary, Seller agrees to look solely to Purchaser for the duties, obligations,
responsibilities and liabilities of Purchaser hereunder and under all of the
documents executed pursuant hereto and neither the constituent partners of
Purchaser nor any partners, members, managers, shareholders, officers,
directors, beneficiaries, trustees or employees of Purchaser or the constituent
partners of Purchaser shall be liable or responsible for any duty, obligation,
responsibility or liability of Purchaser hereunder.

        16.11   Notwithstanding anything set forth or implied herein to the
contrary, Purchaser agrees to look solely to the Seller for the duties,
obligations, responsibilities and liabilities of Seller hereunder and under all
the documents executed pursuant hereto and neither the constituent partners of
Seller nor any partners, members, managers, shareholders, officers, directors,
beneficiaries, trustees or employees of Seller or the constituent partners of
Seller shall be liable or responsible for any duty, obligation, responsibility
or liability of Seller hereunder.
