                                 (WITH NOVATION)

This Assumption Agreement ("Agreement") is dated as of the 12th day of April,
2004 among STATE FARM LIFE INSURANCE COMPANY, an Illinois corporation
("Lender"), BEHRINGER HARVARD ENCLAVE S LP, a Texas limited partnership
("BHES"), BEHRINGER HARVARD ENCLAVE H LP, a Texas limited partnership ("BHEH")
(BHES and BHEH shall be collectively referred to herein "Original Borrower"),
BEHRINGER HARVARD HOLDINGS, LLC, a Texas limited liability company ("BHH"), a
____________ ("Assuming Borrower"), and _______________ ("Principal"). Lender,
Original Borrower, BHH, Assuming Borrower and Principal sometimes may be
referred to collectively as the "Parties" or individually as a "Party."

                                    RECITALS

A.      Lender made a loan (the "Loan") to Original Borrower in the amount of
        $20,000,000 (the "Loan Amount") as evidenced by a Promissory Note dated
        April 12, 2004 in the principal amount of the Loan Amount (the "Note"),
        in which Original Borrower is the maker in favor of Lender, as payee.

B.      The Note is secured by the following documents:

                1.      That certain Deed of Trust and Security Agreement dated
                of even date with the Note, granted by Original Borrower in
                favor of State Farm (the "Lien Agreement"), encumbering the real
                property described in Exhibit A attached hereto (and by this
                reference incorporated herein) (the "Property");

                2.      That certain Assignment of Rents and Leases dated of
                even date with the Note (the "Assignment of Rents"), from
                Original Borrower as assignor in favor of Lender as assignee;
                and

                3.      Two Uniform Commercial Code Financing Statements, (Forms
                UCC-1 and UCC-2), in which Original Borrower is the debtor and
                the Lender is the secured party, and which were, respectively,
                recorded in the office of the Secretary of State of Texas and in
                the office of the Harris County Recorder's Office (collectively,
                the "UCCs").

<PAGE>

C.      The Original Borrower also entered into that certain Environmental
        Indemnification Agreement of even date with the Note, for the benefit of
        the Lender (the "Environmental Indemnity"), which Environmental
        Indemnity was delivered contemporaneously with the closing of the Loan.

D.      As additional consideration to Lender for its agreement to make the
        Loan, BHH entered into the Environmental Indemnity and that certain
        Limited Guaranty of even date with the Note, in favor of Lender
        (collectively, the "Guaranty"), which Guaranty was delivered
        contemporaneously with the closing of the Loan.

E.      The Lien Agreement, the Assignment of Rents, and the UCCs, are
        collectively called the "Security Documents." The Note, the
        Environmental Indemnity, the Guaranty, the Security Documents, and all
        other agreements securing, evidencing, or relating to Original
        Borrower's and/or BHH's obligations under the Loan are collectively
        called the "Loan Documents."

F.      BHES and Assuming Borrower have entered into a Purchase Agreement and
        Escrow Instructions, dated April 8, 2004 (the "Purchase Agreement"), in
        which, among other things, BHES has agreed to sell a ___% undivided
        interest in the Property (the "Undivided Interest") to the Assuming
        Borrower.

G.      In connection with the purchase of the Undivided Interest in the
        Property by Assuming Borrower, the Parties agree, subject to the terms
        and conditions set forth in this Agreement, that (i) Assuming Borrower
        shall assume its pro rata share of the Loan, and (ii) Principal shall
        assume a corresponding pro rata share of obligations of BHH under the
        Guaranty and the Environmental Indemnity; provided, however, that
        Principal shall not be liable for the acts of BHH, but will only be
        fully liable for its own acts and omissions under the Guaranty and the
        Environmental Indemnity.

                                   AGREEMENTS

NOW, THEREFORE, in consideration of the following mutual agreements and other
valuable consideration, the receipt and sufficiency of which are acknowledged
and intending to be legally bound, the Parties agree as follows:

        1.      INCORPORATION OF RECITALS AND EXHIBITS

                The Recitals are incorporated as part of this Agreement, and the
                Parties agree that the above Recitals are accurate.

        2.      OUTSTANDING BALANCE AND LOAN STATUS

                The Parties agree that, as of the Effective Date (as hereinafter
                defined), the outstanding principal balance of the Loan is
                $20,000,000.00; interest is paid

                                     Page 2
<PAGE>

                to April 30, 2004; and the next installment payment of principal
                and interest in the amount of $112,931.18 is due on or before
                JUNE 1, 2004.

        3.      ASSUMING BORROWER'S COVENANT TO PERFORM

                Assuming Borrower hereby unconditionally assumes, covenants, and
                agrees to timely pay and perform all Indebtedness and
                Obligations under the Loan Documents, and to comply with all of
                the terms, covenants, and conditions of those Loan Documents to
                which BHES is a party as if Assuming Borrower originally had
                executed such Loan Documents (including, without limitation, the
                Note and the Environmental Indemnity), instead and in the place
                of BHES. Assuming Borrower is familiar with all terms,
                conditions, and provisions of the Loan Documents, and fully
                comprehends the same, as modified by this Agreement. The
                Parties, however, recognize and acknowledge the qualified
                "limited recourse" nature of the Note and the Loan. Lender
                agrees that notwithstanding anything to the contrary contained
                in the Loan Documents, Assuming Borrower's liability under the
                "limited recourse" provisions in the Note (Paragraph V) and in
                the Lien Agreement (Section 8.11), and under and pursuant to the
                Environmental Indemnity (the "Borrower's Recourse Liability
                Sections"), shall be several (and not joint) and shall be
                limited to _____% of the total liability under the Borrower's
                Recourse Liability Sections, but in any event Assuming Borrower
                shall only be responsible for such liabilities to the extent
                caused by its own actions.

        4.      PRINCIPAL'S COVENANT TO PERFORM

                Principal hereby unconditionally assumes, covenants, and agrees
                to timely pay and perform all the Guaranteed Indebtedness (as
                defined in the Guaranty) and the obligations of BHH under the
                Guaranty and the Environmental Indemnity, and to comply with all
                of the terms, covenants, and conditions of the Guaranty and the
                Environmental Indemnity as if Principal originally had executed
                the Guaranty and the Environmental Indemnity, instead and in the
                place of BHH and, with respect to the Guaranty, liable for its
                acts and omissions to the extent that such acts and omissions
                cause Losses in accordance therewith. Principal is familiar with
                all terms, conditions, and provisions of the Loan Documents, and
                fully comprehends the same, as modified by this Agreement. The
                Parties, however, recognize and acknowledge the qualified
                "limited recourse" nature of the Guaranty and the Loan. Lender
                agrees that notwithstanding anything to the contrary contained
                in the Loan Documents and this Agreement, Principal shall not be
                liable for the acts and omissions of any other guarantor or
                borrower of the Guaranteed Indebtedness under the Guaranty, or
                pursuant to the Environmental Liability (the "Guarantor's
                Recourse Liability Sections"), provided, however, that Principal

                                     Page 3
<PAGE>

                acknowledges and agrees that it shall be fully liable under the
                Guarantor's Recourse Liability Sections but only for each and
                every act and omission by Principal.

        5.      INTENTIONALLY DELETED.

                        the payment or performance by Original Borrower or
                        Assuming Borrower of the Indebtedness and Obligations
                        under the Loan, this Agreement, the Note, the
                        Environmental Indemnity, the Security Documents, or any
                        of the Loan Documents, including, without limitation,
                        any claim for breach of contract, failure to act in good
                        faith, lack of fair dealing, misrepresentation, breach
                        of fiduciary duty, fraud, or negligence. None of

                        offsets, or counterclaims, do presently exist, as
                        additional consideration for this Agreement, Original
                        Borrower, BHH, Assuming Borrower and Principal hereby
                        waive and release them to the fullest extent permitted
                        by applicable law;

                6.2     Lender has not breached any duty to Original Borrower,
                        BHH, Assuming Borrower or Principal in connection with
                        the Loan. Lender has timely and fully performed all
                        obligations which Lender may have had or now has to
                        Original Borrower, BHH, Assuming Borrower and Principal
                        in connection with the Loan;

                        grant any modifications or extensions in connection with
                        the Loan, except as may be set forth specifically in the
                        Loan Documents and this Agreement;

                Lender retains all its rights under the Lien Agreement to
                approve, disapprove, or impose conditions upon any subsequent or
                other sale or transfer.

                        are acceptable to Lender;

                        8.4     [Intentionally deleted]

                        8.5     Evidence satisfactory to Lender that Assuming
                        Borrower is in good standing in the state of formation,
                        and authorized to transact business in Texas; that
                        Principal is in good standing in the state of formation,
                        to the extent Principal is not an individual, and
                        authorized to transact business Texas; that Assuming
                        Borrower and Principal has each authorized the execution
                        of this Agreement, and that the persons executing this
                        Agreement on behalf of the Assuming Borrower and
                        Principal, respectively, have full power and authority
                        to bind the Assuming Borrower and Principal to the same;

                        8.6     As soon as the same shall become available after
                        the closing of the Purchase Agreement, a copy of the
                        recorded vesting deed that transfers title to the
                        Undivided Interest in the Property to Assuming Borrower,
                        a copy of which, along with a copy of the Purchase
                        Agreement, shall have been provided to Lender prior to
                        the closing under the Purchase Agreement.

                        8.7     Such other documents as Lender may reasonably
                        have requested at any time at or prior to the closing of
                        the Purchase Agreement; and

                        8.8     Payment by Original Borrower, BHH, Assuming
                        Borrower and Principal of all costs, premiums, fees, and
                        expenses (including, without limitation, reasonable
                        attorneys' fees) incurred by Lender in the negotiation
                        and preparation of this Agreement and the other
                        documents described herein, including any Title Policy.

                Within fifteen (15) days after the written request of Original
                Borrower or BHH, Lender will either (i) confirm that all of the
                conditions set forth in this paragraph have been satisfied or
                are deemed satisfied, or (ii) specify which conditions remain
                outstanding.

        9.      CLOSING

                Closing under this Agreement shall occur contemporaneously with
                the closing under the Purchase Agreement. If the Purchase
                Agreement does not itself close, and/or all the conditions set
                forth in paragraph 8 are not satisfied, then this Agreement
                automatically shall terminate, and none of the Parties shall
                have any further liability or obligation to one another under
                this Agreement, and the respective rights, duties, and
                obligations of the Parties shall continue unmodified

                                     Page 7

<PAGE>

                as if this Agreement had never been negotiated or executed,
                except for the continuing obligation of the Original Borrower,
                BHH, Assuming Borrower and/or Principal to pay all costs, fees,
                and expenses (including attorneys' fees) incurred by Lender in
                connection with the negotiation and preparation of this
                Agreement and the other documents described therein.

        10.     AFFIRMATION

                Original Borrower, BHH, Assuming Borrower, to Assuming
                Borrower's current actual knowledge, and Principal, to
                Principal's current actual knowledge, hereby affirm (on behalf
                of itself only and not on behalf of the other party) that, as of
                the Effective Date, the representations and warranties of
                Original Borrower set forth in the Loan Documents are and remain
                true and correct as though made on and as of the Effective Date
                and are hereby affirmed, ratified, and confirmed by Assuming
                Borrower. Assuming Borrower will immediately notify Lender of
                any change or discovered inaccuracy in the representations and
                warranties contained in the Loan Documents, provided that
                Assuming Borrower's duty to notify Lender of any such inaccuracy
                shall only apply to presently existing inaccuracies which
                existed before the Effective Date or any future inaccuracies.
                Assuming Borrower and Principal hereby confirm that the Loan
                Documents to which they are a party are and shall remain
                enforceable against them in accordance with their respective
                terms, shall continue to be in full force and effect, and are
                hereby confirmed and ratified in all respects. Assuming Borrower
                and Principal agree that this Agreement shall not impair the
                Security Documents, the Environmental Indemnity or any lien
                securing the Note, that such liens are not waived, released, or
                extinguished in any manner, and that such liens are hereby
                acknowledged to be valid and existing and shall continue to
                secure payment of the Note and all other obligations under the
                Loan Documents.

        11.     SECURITY

                Assuming Borrower's performance under this Agreement, the Note
                and all other Loan Documents shall continue to be secured by the
                Security Documents, including without limitation the Lien
                Agreement and the Assignment of Rents. After the Effective Date,
                all references to the Loan Documents shall include this
                Agreement.

        12.     NOTICES, CONSENTS, AND APPROVALS

                Any notice, consent, or approval that Lender or Assuming
                Borrower may desire or be required to give to the other shall be
                in writing and shall be mailed or delivered to the intended
                recipient thereof at its address set forth below or at such
                other address as such intended recipient may, from time to time,

                thereof is given. Except as otherwise specifically required
                herein, notice of the exercise of any right or option granted to

                Captions and headings are for convenience and reference only and
                do not define, limit, or affect the contents of this Agreement.
                Reference to "paragraphs" or "sections" refer to this Agreement
                unless stated otherwise. All grammatical usage shall be deemed
                to refer to the masculine, feminine, neuter, singular, or plural
                as the context and identity of any persons may require.
                Capitalized terms not otherwise defined in this Agreement shall
                have the meanings set forth in the Loan Documents.

        14.     SEVERABILITY AND INTERPRETATION

                The invalidity or unenforceability of any provision of this
                Agreement does not affect the remaining provisions. This
                Agreement shall be construed as if it excluded any invalid or
                unenforceable provision, which shall be severed from this
                Agreement. Whenever possible, this Agreement shall be
                interpreted so as to be valid under applicable law, and shall
                not be construed strictly in favor of or against any particular
                Party, including any Party who drafted or prepared this
                Agreement, but instead according to its plain meaning to give
                effect to its intended purposes.

        15.     GOVERNING LAW

                This Agreement is governed by the laws of the State of Texas,
                including its choice of law principles. The Parties consent and
                submit to the non-exclusive jurisdiction of the courts of the
                State of Texas and the United States District Court for the
                Southern District of Texas, to be venued in Harris County,
                Texas, concerning any action or proceeding involving the Lender
                and arising under this Agreement, the Loan Documents, or the
                Loan.

        16.     COUNTERPARTS

                This Agreement may be executed in identical counterparts, each
                of which upon execution shall be deemed an original, but all of
                which together shall constitute one document. Partially executed
                signature or acknowledgment pages of any one counterpart may be
                combined with or attached to any other partially executed
                counterpart of this Agreement.

        17.     ENTIRETY; MODIFICATION

                This Agreement constitutes the entire agreement of the Parties
                with respect to the assumption contemplated hereby of the Loan.
                There are no verbal agreements between the Parties. This
                Agreement and the Loan Documents as amended by this Agreement
                may be amended or modified only by a written document signed by
                all the Parties.

        18.     TIME

                TIME IS OF THE ESSENCE FOR THE PERFORMANCE OF EACH PROVISION OF
                THIS AGREEMENT. If this Agreement requires any action to be
                performed on a date which is not a "business" day (a Saturday,
                Sunday, or federal or state legal holiday), such action shall be
                validly performed on the next succeeding business day.

        19.     NEGOTIATED AGREEMENT

                This Agreement is the result of arms-length negotiations between
                the Parties, each of whom has been represented by counsel, and
                no Party has acted under duress or compulsion, whether legal,
                economic, or otherwise.

        20.     BINDING EFFECT

                This Agreement is binding upon and inures to the benefit of the
                Parties and their respective permitted successors and assign.
                However, this provision shall not be deemed to be a consent by
                Lender to any further sale or transfer of the Property by
                Assuming Borrower.

        21.     EFFECTIVE DATE

                This Agreement is effective as of April 12, 2004 (the "Effective
                Date"), which is the date of closing under the Purchase
                Agreement described above.

        22.     FURTHER ASSURANCES

                On the date hereof, or thereafter, if necessary, Assuming
                Borrower agrees to execute and deliver to or cause to be
                executed and delivered to Lender such further instruments as the
                Lender may reasonably request and take such other action as the
                Lender may reasonably require to carry out more effectively the
                transactions contemplated by this Agreement.

worth of not less than Nine Million Dollars ($9,000,000.00).

        3.      CHARACTER OF OBLIGATIONS.

                (1)     This is an absolute, continuing and unconditional
        guaranty of payment and not of collection and if at any time or from
        time to time there is no outstanding Guaranteed Indebtedness, the
        obligations of Guarantor with respect to any and all Guaranteed
        Indebtedness incurred thereafter shall not be affected. This Guaranty
        and the Guarantor's obligations hereunder are irrevocable and, in the
        event of Guarantor's death, shall be binding upon Guarantor's estate
        pursuant to PARAGRAPH 10 herein. All of the Guaranteed Indebtedness
        shall be conclusively presumed to have been made or acquired in
        acceptance hereof. GUARANTOR SHALL BE LIABLE, JOINTLY AND SEVERALLY,
        WITH BORROWER AND ANY OTHER GUARANTOR OF ALL OR ANY PART OF THE
        GUARANTEED INDEBTEDNESS.

                (2)     State Farm may, at its sole discretion and without
        impairing its rights hereunder, (I) apply any payments on the Guaranteed
        Indebtedness that State Farm receives from Borrower or any other source
        other than Guarantor to that portion of the Guaranteed Indebtedness, if
        any, not guaranteed hereunder and (II) apply any proceeds it receives as
        a result of the foreclosure or other realization on any collateral for
        the Guaranteed Indebtedness to that portion, if any, of the Guaranteed
        Indebtedness not guaranteed hereunder or to any other indebtedness
        secured by such collateral.

                (3)     Guarantor agrees that its obligations hereunder shall
        not be released, diminished, impaired, reduced or affected by the
        existence of any other guaranty or the payment by any other guarantor of
        all or any part of the Guaranteed Indebtedness and Guarantor's
        obligations hereunder shall continue until State Farm has received
        payment in full of the Guaranteed Indebtedness.

<PAGE>

                (4)     Guarantor's obligations hereunder shall not be released,
        diminished, impaired, reduced or affected by, nor shall any provision
        contained herein be deemed to be a limitation upon, the amount of credit
        which State Farm may extend to Borrower, the number of transactions
        between State Farm and Borrower, payments by Borrower to State Farm or
        State Farm's allocation of payments by Borrower.

        such financial condition or collateral as an inducement to enter into
        this Guaranty; and

        effect upon the financial condition of Guarantor or upon such security
        or might cause a default under any of the Loan Documents, (ii) any claim
        or controversy which might become the subject of such litigation or

        Borrower or any other person or entity, whether by separate action or by
        joinder.

        COVENANTS OF GUARANTOR SET FORTH HEREIN, GUARANTOR HEREBY FURTHER WAIVES
        AND RELEASES ALL CLAIMS, CAUSES OF ACTION, DEFENSES AND OFFSETS FOR ANY

        whether occurring by reason of law or otherwise; (iv) the taking or

                (2)     This Guaranty shall continue to be effective or be

        of Borrower, Guarantor, any other guarantor of all or any part of the
        Guaranteed Indebtedness, or otherwise, all as though such payment had
        not been made.

                (3)     In the event Borrower is a corporation, joint stock
        association or partnership, or is hereafter incorporated, none of the
        following shall affect Guarantor's liability hereunder: (i) the
        unenforceability of all or any part of the Guaranteed Indebtedness
        against Borrower by reason of the fact that the Guaranteed Indebtedness
        exceeds the amount permitted by law; (ii) the act of creating all or any
        part of the Guaranteed Indebtedness is ultra vires; or (iii) the
        officers or partners creating all or any part of the Guaranteed
        Indebtedness acted in excess of their authority. Guarantor hereby
        acknowledges that withdrawal from, or termination of, any ownership
        interest in Borrower now or hereafter owned or held by Guarantor shall
        not alter, affect or in any way limit the obligations of Guarantor
        hereunder.

        8.      ACTIONS AGAINST GUARANTOR. In the event of a default in the
payment or performance of all or any part of the Guaranteed Indebtedness when
such Guaranteed Indebtedness becomes due, whether by its terms, by acceleration
or otherwise, Guarantor shall, without notice or demand, promptly pay the amount
due thereon to State Farm, in lawful money of the United States, at State Farm's
address set forth in SUBPARAGRAPH 1(I) above. One or more successive or
concurrent actions may be brought against Guarantor, either in the same action
in which Borrower is sued or in separate actions, as often as State Farm deems
advisable. The exercise by State Farm of any right or remedy under this Guaranty
or under any other agreement

<PAGE>

or instrument, at law, in equity or otherwise, shall not preclude concurrent or
subsequent exercise of any other right or remedy. The books and records of State
Farm shall be admissible in evidence in any action or proceeding involving this
Guaranty and shall be PRIMA FACIE evidence of the payments made on, and the
outstanding balance of, the Guaranteed Indebtedness.

        9.      PAYMENT BY GUARANTOR. Whenever Guarantor pays any sum which is
or may become due under this Guaranty, written notice must be delivered to State
Farm contemporaneously with such payment. Such notice shall be effective for
purposes of this paragraph when contemporaneously with such payment State Farm
receives such notice either by: (a) personal delivery to the address and
designated department of State Farm identified in SUBPARAGRAPH 1(A) above, or
(b) United States mail, certified or registered, return receipt requested,
postage prepaid, addressed to State Farm at the address shown in SUBPARAGRAPH
1(A) above. In the absence of such notice to State Farm by Guarantor in
compliance with the provisions hereof, any sum received by State Farm on account
of the Guaranteed Indebtedness shall be conclusively deemed paid by Borrower.

        10.     DEATH OF GUARANTOR. In the event of the death of Guarantor, the
obligations of the deceased Guarantor under this Guaranty shall continue as an
obligation against Guarantor's estate as to all of the Guaranteed Indebtedness.
The terms and conditions of this Guaranty, including without limitation the
consents and waivers set forth in PARAGRAPH 6 hereof, shall remain in effect
with respect to the Guaranteed Indebtedness in the same manner as if Guarantor
had not died.

        11.     NOTICE OF SALE. In the event that Guarantor is entitled to
receive any notice (which shall be given to the address listed on the signature
page hereof) under the Uniform Commercial Code, as it exists in the state
governing any such notice, of the sale or other disposition of any collateral
securing all or any part of the Guaranteed Indebtedness or this Guaranty,
reasonable notice shall be deemed given in the manner set forth in SECTION 8.1
of the Deed of Trust and Security Agreement executed by Borrower to the benefit
of State Farm dated of even date herewith.

        12.     WAIVER BY STATE FARM. No delay on the part of State Farm in
exercising any right hereunder or failure to exercise the same shall operate as
a waiver of such right. In no event shall any waiver of the provisions of this
Guaranty be effective unless the same be in writing and signed by an officer of
State Farm, and then only in the specific instance and for the purpose given.

        13.     SUCCESSORS AND ASSIGNS. This Guaranty is for the benefit of
State Farm, its successors and assigns. This Guaranty is binding upon Guarantor
and Guarantor's heirs, executors, administrators, personal representatives and
successors, including without limitation any person or entity obligated by
operation of law upon the reorganization, merger, consolidation or other change
in the organizational structure of Guarantor.

        14.     COSTS AND EXPENSES. Guarantor shall pay on demand by State Farm
all costs and expenses, including without limitation all reasonable attorneys'
fees, incurred by State Farm in

connection with the preparation, administration, enforcement and/or collection
of this Guaranty. This covenant shall survive the payment of the Guaranteed
Indebtedness.

        15.     SEVERABILITY. If any provision of this Guaranty is held by a
court of competent jurisdiction to be illegal, invalid or unenforceable under
present or future laws, such provision shall be fully severable, shall not
impair or invalidate the remainder of this Guaranty and the effect thereof shall
be confined to the provision held to the illegal, invalid or unenforceable.

        16.     NO OBLIGATION. Nothing contained herein shall be construed as an
obligation on the part of State Farm to extend or continue to extend credit to
Borrower.

        17.     AMENDMENT. No modification or amendment of any provision of this
Guaranty, nor consent to any departure by Guarantor therefrom, shall be
effective unless the same shall be in writing and signed by an officer of State
Farm, and then shall be effective only in the specific instance and for the
purpose for which given.

        18.     CUMULATIVE RIGHTS. All rights and remedies of State Farm
hereunder are cumulative of each other and of every other right or remedy which
State Farm may otherwise have at law or in equity or under any instrument or
agreement, and the exercise of one or more of such rights or remedies shall not
prejudice or impair the concurrent or subsequent exercise of any other rights or
remedies.

        19.     GOVERNING LAW. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

        20.     VENUE. Federal and state courts within HARRIS COUNTY, TEXAS
shall have jurisdiction over any and all disputes arising under or pertaining to
this Guaranty and venue for any such disputes shall be in the county where the
Premises is located.

        21.     COMPLIANCE WITH APPLICABLE USURY LAWS. Notwithstanding any other
provision of this Guaranty or of any instrument or agreement evidencing,
governing or securing all or any part of the Guaranteed Indebtedness, Guarantor
and State Farm by its acceptance hereof agree that Guarantor shall never be
required or obligated to pay interest in excess of the maximum nonusurious
interest rate as may be authorized by applicable law for the written contracts
which constitute the Guaranteed Indebtedness. It is the intention of Guarantor
and State Farm to conform strictly to the applicable laws which limit interest
rates, any of the aforesaid contracts for interest, if and to the extent payable
by Guarantor, shall be held to be subject to reduction to the maximum
nonusurious interest rate allowed under said law.

        22.     DESCRIPTIVE HEADINGS AND DEFINITIONS. The headings in this
Guaranty are for convenience only and shall not define or limit provisions
hereof. All capitalized terms used herein, but not defined herein, shall have
the same meaning as set forth in the Promissory Note.

        23.     GENDER. Within this Guaranty, words of any gender shall be held
and construed to include the other gender.
