ARTICLE II
PAYMENT TERMS

Section 2.1     PAYMENT OF PRINCIPAL AND INTEREST. All accrued but unpaid
interest on the principal balance of this Note outstanding from time to time
shall be payable on each Payment Date commencing September 15, 2007. The then
outstanding principal balance of this Note and all accrued but unpaid interest
thereon shall be due and payable on the Maturity Date. Borrower may from time to
time during the term of this Note borrow, partially or wholly repay its
outstanding borrowings, and reborrow, subject to all of the limitations, terms
and conditions of this Note and of the Loan Documents; provided however, that
the total outstanding borrowings under this Note shall not at any time exceed
the principal amount stated above. The unpaid principal balance of this Note at
any time shall be the total amounts advanced hereunder by Lender less the amount
of principal payments made hereon by or for Borrower, which balance may be
endorsed hereon from time to time by Lender or otherwise noted in Lender's
records, which notations shall be, absent manifest error, conclusive evidence of
the amounts owing hereunder from time to time.

Section 2.2     APPLICATION. Except as expressly provided herein to the
contrary, all payments on this Note shall be applied in the following order of
priority: (i) the payment or reimbursement of any expenses, costs or obligations
(other than the outstanding principal balance hereof and interest hereon) for
which either Borrower shall be obligated or Lender shall be entitled pursuant to
the provisions of this Note or the other Loan Documents, (ii) the payment of
accrued but unpaid interest hereon, and (iii) the payment of all or any portion
of the principal balance hereof then outstanding hereunder, in the direct order
of maturity. If an Event of Default exists under this Note or under any of the
other Loan Documents, then Lender may, at the sole option of Lender, apply any
such payments, at any time and from time to time, to any of the items specified
in clauses (i), (ii) or (iii) above without regard to the order of priority
otherwise specified in this Section 2.2 and any application to the outstanding
principal balance hereof may be made in either direct or inverse order of
maturity.

Section 2.3     PAYMENTS. All payments under this Note made to Lender shall be
made in immediately available funds at 1807 Ross Avenue, Suite 400, Dallas,
Texas 75201 (or at such other place as Lender, in Lender's sole discretion, may
have established by delivery of written notice thereof to Borrower from time to
time), without offset, in lawful money of the United States of America, which
shall at the time of payment be legal tender in payment of all debts and dues,
public and private. Payments by check or draft shall not constitute payment in
immediately available funds until the required amount is actually received by
Lender in full. Payments in immediately available funds received by Lender in
the place designated for payment on a Business Day prior to 11:00 a.m. Dallas,
Texas time at said place of payment shall be credited prior to the close of
business on the Business Day received, while payments received by Lender on a
day other than a Business Day or after 11:00 a.m. Dallas, Texas time on a
Business Day shall not be credited until the next succeeding Business Day. If
any payment of principal or interest on this Note shall become due and payable
on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day. Any such extension of time for payment shall be
included in computing interest which has accrued and shall be payable in
connection with such payment.

Section 2.4     RATE, ETC. Subject to the terms and conditions set forth below,
the unpaid principal of this Note shall bear interest at the Note Rate. Borrower
shall designate each LIBOR Interest Period by giving Lender written notice of
its selection before 11:00 a.m. (Dallas, Texas time) on the LIBOR Determination
Date, which selection shall be irrevocable, for each LIBOR Interest Period. No
LIBOR Interest Period may extend beyond the Maturity Date. If Borrower shall
fail to select a LIBOR Interest Period the unpaid principal balance of this Note
shall bear interest at LIBOR plus the Applicable LIBOR Margin for successive
LIBOR Interest Periods of one month each until Borrower selects another LIBOR
Interest Period in accordance with the terms hereof. If an Event of Default has
occurred and is continuing, the option to select LIBOR Interest Periods shall
terminate, and this Note shall bear interest in accordance with Section 2.9 of
this Note. The determination by Lender of the Note Rate shall, in the absence of
manifest error, be conclusive and binding in all respects. Notwithstanding
anything contained herein to the contrary, if (i) at any time, Lender determines
(which determination shall be conclusive in the absence of manifest error) that
any applicable law or regulation or any change therein or the interpretation or
application thereof or compliance therewith by Lender (A) prohibits, restricts
or makes impossible the charging of interest based on LIBOR or (B) shall make it
unlawful for Lender to make or maintain the indebtedness evidenced by this Note
in eurodollars, or (ii) at the time of or prior to the determination of LIBOR,
Lender determines (which determination shall be conclusive in the absence of
manifest error) that by reason of circumstances affecting the London interbank
market generally, (A) deposits in United States Dollars in the relevant amounts
and of the relevant maturity are not available to Lender in the London interbank
market, (B) LIBOR does not adequately and fairly reflect the cost to Lender of
making or maintaining the loan, due to changes in administrative costs, fees,
tariffs and taxes and other matters outside of Lender's reasonable control, or
(C) adequate and fair means do not or will not exist for determining LIBOR as
set forth in this Note, then Lender shall give Borrower prompt notice thereof,
and this Note shall bear interest, and continue to bear interest until Lender
determines that the applicable circumstance described in the foregoing clauses
(i) (A) or (B) or (ii) (A), (B) or (C) no longer pertains, at the Base Rate
(adjusted as may be necessary by Lender to correspond as closely as possible to
the Applicable Rate existing on the date of Lender's determination set forth in
(i) or (ii) above), which Base Rate shall adjust from time to time as and when
the Prime Rate changes.

Section 2.5     COMPUTATION PERIOD. Interest on the indebtedness evidenced by
this Note shall be computed on the basis of a three hundred sixty (360) day year
and shall accrue on the actual number of days elapsed for any whole or partial
month in which interest is being calculated. In computing the number of days
during which interest accrues, the day on which funds are initially advanced
shall be included regardless of the time of day such advance is made, and the
day on which funds are repaid shall be included unless repayment is credited
prior to the close of business on the Business Day received as provided in
Section 2.3 hereof.

Section 2.6     PREPAYMENT. Borrower shall have the right to prepay, at any time
and from time to time without fee, premium or penalty (except as noted below),
all or any portion of the outstanding principal balance hereof, provided,
however, that such prepayment shall also include any and all accrued but unpaid
interest on the amount of principal being so prepaid through and including the
date of prepayment, plus any other sums which have become due to Lender under
the other Loan Documents on or before the date of prepayment, but which have not
been fully paid.

Section 2.7     UNCONDITIONAL PAYMENT. Borrower is and shall be obligated to pay
all principal, interest and any and all other amounts which become payable under
this Note or under any of the other Loan Documents absolutely and
unconditionally and without any abatement, postponement, diminution or deduction
whatsoever and without any reduction for counterclaim or setoff whatsoever. If
at any time any payment received by Lender hereunder shall be deemed by a court
of competent jurisdiction to have been a voidable preference or fraudulent
conveyance under any Debtor Relief Law, then the obligation to make such payment
shall survive any cancellation or satisfaction of this Note or return thereof to
Borrower and shall not be discharged or satisfied with any prior payment thereof
or cancellation of this Note, but shall remain a valid and binding obligation
enforceable in accordance with the terms and provisions hereof, and such payment
shall be immediately due and payable upon demand.

Section 2.8     PARTIAL OR INCOMPLETE PAYMENTS. Remittances in payment of any
part of this Note other than in the required amount in immediately available
funds at the place where this Note is payable shall not, regardless of any
receipt or credit issued therefor, constitute payment until the required amount
is actually received by Lender in full in accordance herewith and shall be made
and accepted subject to the condition that any check or draft may be handled for
collection in accordance with the practice of the collecting bank or banks.
Acceptance by Lender of any payment in an amount less than the full amount then
due shall be deemed an acceptance on account only, and the failure to pay the
entire amount then due shall be and continue to be an Event of Default in the
payment of this Note.

Section 2.9     DEFAULT INTEREST RATE, ETC. For so long as any Event of Default
exists under this Note or under any of the other Loan Documents, regardless of
whether or not there has been an acceleration of the indebtedness evidenced by
this Note, and at all times after the maturity of the indebtedness evidenced by
this Note (whether by acceleration or otherwise), and in addition to all other
rights and remedies of Lender hereunder, interest shall accrue on the
outstanding principal balance hereof at the Default Interest Rate, and such
accrued interest shall be immediately due and payable. Borrower acknowledges
that it would be extremely difficult or impracticable to determine Lender's
actual damages resulting from any late payment or Event of Default, and such
late charges and accrued interest are reasonable estimates of those damages and
do not constitute a penalty.

ARTICLE III
EVENT OF DEFAULT AND REMEDIES

Section 3.1     EVENT OF DEFAULT. The occurrence or happening, at any time and
from time to time, of any event or condition which constitutes an Event of
Default under the Loan Agreement shall immediately constitute an "Event of
Default" under this Note.

Section 3.2     REMEDIES. Upon the occurrence of an Event of Default, Lender
shall have the immediate right, at the sole discretion of Lender and without
notice, demand, presentment, notice of nonpayment or nonperformance, protest,
notice of protest, notice of intent to accelerate, notice of acceleration, or
any other notice or any other action (ALL OF WHICH BORROWER HEREBY EXPRESSLY
WAIVES AND RELINQUISHES) (i) to declare the entire unpaid balance of the
indebtedness evidenced by this Note (including, without limitation, the
outstanding principal balance hereof, including all sums advanced or accrued
hereunder or under any other Loan Document, and all accrued but unpaid interest
thereon) at once immediately due and payable (and upon such declaration, the
same shall be at once immediately due and payable) and may be collected
forthwith, whether or not there has been a prior demand for payment and
regardless of the stipulated date of maturity, (ii) to foreclose any liens and
security interests securing payment hereof or thereof (including, without
limitation, any liens and security interests covering any portion of the
Mortgaged Property), and (iii) to exercise any of Lender's other rights, powers,
recourses and remedies under this Note, under any other Loan Document, or at law
or in equity, and the same (w) shall be cumulative and concurrent, (x) may be
pursued separately, singly, successively, or concurrently against Borrower or
others obligated for the repayment of this Note or any part hereof, or against
any one or more of them, or against the Mortgaged Property, at the sole
discretion of Lender, (y) may be exercised as often as occasion therefor shall
arise, it being agreed by Borrower that the exercise, discontinuance of the
exercise of or failure to exercise any of the same shall in no event be
construed as a waiver or release thereof or of any other right, remedy, or
recourse, and (z) are intended to be, and shall be, nonexclusive. All rights and
remedies of Lender hereunder and under the other Loan Documents shall extend to
any period after the initiation of foreclosure proceedings, judicial or
otherwise, with respect to the Mortgaged Property or any portion thereof.
Without limiting the provisions of Section 4.18 hereof, if this Note, or any
part hereof, is collected by or through an attorney-at-law, Borrower agrees to
pay all reasonable costs and expenses of collection, including, but not limited
to, reasonable Lender's attorneys' fees, whether or not any legal action shall
be instituted to enforce this Note. This Note is also subject to acceleration as
provided in the Loan Agreement.

ARTICLE IV
GENERAL PROVISIONS

Section 4.1     NO WAIVER; AMENDMENT. No failure to accelerate the indebtedness
evidenced by this Note by reason of an Event of Default hereunder, acceptance of
a partial or past due payment, or indulgences granted from time to time shall be
construed (i) as a novation of this Note or as a reinstatement of the
indebtedness evidenced by this Note or as a waiver of such right of acceleration
or of the right of Lender thereafter to insist upon strict compliance with the
terms of this Note, or (ii) to prevent the exercise of such right of
acceleration or any other right granted under this Note, under any of the other
Loan Documents or by any applicable laws. Borrower hereby expressly waives and
relinquishes the benefit of any statute or rule of law or equity now provided,
or which may hereafter be provided, which would produce a result contrary to or
in conflict with the foregoing. The failure to exercise any remedy available to
Lender shall not be deemed to be a waiver of any rights or remedies of Lender
under this Note or under any of the other Loan Documents, or at law or in
equity. No extension of the time for the payment of this Note or any installment
due hereunder, made by agreement with any person now or hereafter liable for the
payment of this Note, shall operate to release, discharge, modify, change or
affect the original liability of Borrower under this Note, either in whole or in
part, unless Lender specifically, unequivocally and expressly agrees otherwise
in writing. This Note may not be changed orally, but only by an agreement in
writing signed by the party against whom enforcement of any waiver, change, or
modification is sought.

Section 4.2     WAIVERS. EXCEPT AS SPECIFICALLY PROVIDED IN THE LOAN DOCUMENTS
TO THE CONTRARY, BORROWER AND ANY ENDORSERS OR GUARANTORS HEREOF SEVERALLY WAIVE
AND RELINQUISH PRESENTMENT FOR PAYMENT, DEMAND, NOTICE OF NONPAYMENT OR
NONPERFORMANCE, PROTEST, NOTICE OF PROTEST, NOTICE OF INTENT TO ACCELERATE,
NOTICE OF ACCELERATION OR ANY OTHER NOTICES OR ANY OTHER ACTION. BORROWER AND
ANY ENDORSERS OR GUARANTORS HEREOF SEVERALLY WAIVE AND RELINQUISH, TO THE
FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO THE BENEFITS OF ANY MORATORIUM,
REINSTATEMENT, MARSHALING, FORBEARANCE, VALUATION, STAY, EXTENSION, REDEMPTION,
APPRAISEMENT, EXEMPTION AND HOMESTEAD NOW OR HEREAFTER PROVIDED BY THE
CONSTITUTION AND LAWS OF THE UNITED STATES OF AMERICA AND OF EACH STATE THEREOF,
BOTH AS TO ITSELF AND IN AND TO ALL OF ITS PROPERTY, REAL AND PERSONAL, AGAINST
THE ENFORCEMENT AND COLLECTION OF THE OBLIGATIONS EVIDENCED BY THIS NOTE OR BY
THE OTHER LOAN DOCUMENTS.

Section 4.3     INTEREST PROVISIONS.

(a)     Savings Clause. It is expressly stipulated and agreed to be the intent
of Borrower and Lender at all times to comply strictly with the applicable Texas
law governing the maximum rate or amount of interest payable on the indebtedness
evidenced by this Note and the Related Indebtedness (or applicable United States
federal law to the extent that it permits Lender to contract for, charge, take,
reserve or receive a greater amount of interest than under Texas law). If the
applicable law is ever judicially interpreted so as to render usurious any
amount (i) contracted for, charged, taken, reserved or received pursuant to this
Note, any of the other Loan Documents or any other communication or writing by
or between Borrower and Lender related to the transaction or transactions that
are the subject matter of the Loan Documents, (ii) contracted for, charged,
taken, reserved or received by reason of Lender's exercise of the option to
accelerate the maturity of this Note and/or the Related Indebtedness, or
(iii) Borrower will have paid or Lender will have received by reason of any
voluntary prepayment by Borrower of this Note and/or the Related Indebtedness,
then it is Borrower's and Lender's express intent that all amounts charged in
excess of the Maximum Lawful Rate shall be automatically canceled, ab initio,
and all amounts in excess of the Maximum Lawful Rate theretofore collected by
Lender shall be credited on the principal balance of this Note and/or the
Related Indebtedness (or, if this Note and all Related Indebtedness have been or
would thereby be paid in full, refunded to Borrower), and the provisions of this
Note and the other Loan Documents shall immediately be deemed reformed and the
amounts thereafter collectible hereunder and thereunder reduced, without the
necessity of the execution of any new document, so as to comply with the
applicable law, but so as to permit the recovery of the fullest amount otherwise
called for hereunder and thereunder; provided, however, if this Note has been
paid in full before the end of the stated term of this Note, then Borrower and
Lender agree that Lender shall, with reasonable promptness after Lender
discovers or is advised by Borrower that interest was received in an amount in
excess of the Maximum Lawful Rate, either refund such excess interest to
Borrower and/or credit such excess interest against this Note and/or any Related
Indebtedness then owing by Borrower to Lender. Borrower hereby agrees that as a
condition precedent to any claim seeking usury penalties against Lender,
Borrower will provide written notice to Lender, advising Lender in reasonable
detail of the nature and amount of the violation, and Lender shall have sixty
(60) days after receipt of such notice in which to correct such usury violation,
if any, by either refunding such excess interest to Borrower or crediting such
excess interest against this Note and/or the Related Indebtedness then owing by
Borrower to Lender. All sums contracted for, charged, taken, reserved or
received by Lender for the use, forbearance or detention of any debt evidenced
by this Note and/or the Related Indebtedness shall, to the extent permitted by
applicable law, be amortized or spread, using the actuarial method, throughout
the stated term of this Note and/or the Related Indebtedness (including any and
all renewal and extension periods) until payment in full so that the rate or
amount of interest on account of this Note and/or the Related Indebtedness does
not exceed the Maximum Lawful Rate from time to time in effect and applicable to
this Note and/or the Related Indebtedness for so long as debt is outstanding. In
no event shall the provisions of Chapter 346 of the Texas Finance Code (which
regulates certain revolving credit loan accounts and revolving triparty
accounts) apply to this Note and/or any of the Related Indebtedness.
Notwithstanding anything to the contrary contained herein or in any of the other
Loan Documents, it is not the intention of Lender to accelerate the maturity of
any interest that has not accrued at the time of such acceleration or to collect
unearned interest at the time of such acceleration.

(b)     Ceiling Election. To the extent that Lender is relying on Chapter 303 of
the Texas Finance Code to determine the Maximum Lawful Rate payable on the Note
and/or any other portion of the Indebtedness, Lender will utilize the weekly
ceiling from time to time in effect as provided in such Chapter 303, as amended.
To the extent United States federal law permits Lender to contract for, charge,
take, receive or reserve a greater amount of interest than under Texas law,
Lender will rely on United States federal law instead of such Chapter 303 for
the purpose of determining the Maximum Lawful Rate. Additionally, to the extent
permitted by applicable law now or hereafter in effect, Lender may, at its
option and from time to time, utilize any other method of establishing the
Maximum Lawful Rate under such Chapter 303 or under other applicable law by
giving notice, if required, to Borrower as provided by applicable law now or
hereafter in effect.

Section 4.4     USE OF FUNDS. Borrower hereby warrants, represents and covenants
that (i) the loan evidenced by this Note is made to Borrower solely for the
purpose of acquiring or carrying on a business or commercial enterprise, (ii)
all proceeds of this Note shall be used only for business and commercial
purposes, and (iii) no funds disbursed hereunder shall be used for personal,
family, agricultural or household purposes.

Section 4.5     FURTHER ASSURANCES AND CORRECTIONS. From time to time, at the
request of Lender, Borrower will (i) promptly correct any defect, error or
omission which may be discovered in the contents of this Note or in any other
Loan Document or in the execution or acknowledgment thereof; (ii) execute,
acknowledge, deliver, record and/or file (or cause to be executed, acknowledged,
delivered, recorded and/or filed) such further documents and instruments
(including, without limitation, further deeds of trust, security agreements,
financing statements, continuation statements and assignments of rents) and
perform such further acts and provide such further assurances as may be
necessary, desirable, or proper, in Lender's opinion, (A) to carry out more
effectively the purposes of this Note and the Loan Documents and the
transactions contemplated hereunder and thereunder, (B) to confirm the rights
created under this Note and the other Loan Documents, (C) to protect and further
the validity, priority and enforceability of this Note and the other Loan
Documents and the liens and security interests created thereby, and (D) to
subject to the Loan Documents any property of Borrower intended by the terms of
any one or more of the Loan Documents to be encumbered by the Loan Documents;
and (iii) pay all costs in connection with any of the foregoing.

Section 4.6     WAIVER OF JURY TRIAL. BORROWER, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, HEREBY KNOWINGLY, INTENTIONALLY, IRREVOCABLY, UNCONDITIONALLY
AND VOLUNTARILY, WITH AND UPON THE ADVICE OF COMPETENT COUNSEL, WAIVES,
RELINQUISHES AND FOREVER FORGOES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR
PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO THIS NOTE OR
ANY CONDUCT, ACT OR OMISSION OF LENDER OR BORROWER, OR ANY OF THEIR DIRECTORS,
OFFICERS, PARTNERS, MEMBERS, EMPLOYEES, AGENTS OR ATTORNEYS, OR ANY OTHER
PERSONS AFFILIATED WITH LENDER OR BORROWER, IN EACH OF THE FOREGOING CASES,
WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE.

Section 4.7     GOVERNING LAW; SUBMISSION TO JURISDICTION. This Note is executed
and delivered as an incident to a lending transaction negotiated and consummated
in Dallas County, Texas, and shall be governed by and construed in accordance
with the laws of the State of Texas. Borrower, for itself and its successors and
assigns, hereby irrevocably (i) submits to the nonexclusive jurisdiction of the
state and federal courts in Texas, (ii) waives, to the fullest extent permitted
by law, any objection that it may now or in the future have to the laying of
venue of any litigation arising out of or in connection with this Note or any
Loan Document brought in the District Court of Dallas County, Texas, or in the
United States District Court for the Northern District of Texas, (iii) waives
any objection it may now or hereafter have as to the venue of any such action or
proceeding brought in such court or that such court is an inconvenient forum,
and (iv) agrees that any legal proceeding against any party to any of the Loan
Documents arising out of or in connection with any of the Loan Documents may be
brought in one of the foregoing courts. Borrower hereby agrees that service of
process upon Borrower may be made by certified or registered mail, return
receipt requested, at its address specified herein. Nothing herein shall affect
the right of Lender to serve process in any other manner permitted by law or
shall limit the right of Lender to bring any action or proceeding against
Borrower or with respect to any of Borrower's property in courts in other
jurisdictions. The scope of each of the foregoing waivers is intended to be all
encompassing of any and all disputes that may be filed in any court and that
relate to the subject matter of this transaction, including, without limitation,
contract claims, tort claims, breach of duty claims, and all other common law
and statutory claims. Borrower acknowledges that these waivers are a material
inducement to Lender's agreement to enter into the agreements and obligations
evidenced by the Loan Documents, that Lender has already relied on these waivers
and will continue to rely on each of these waivers in related future dealings.
The waivers in this Section 4.7 are irrevocable, meaning that they may not be
modified either orally or in writing, and these waivers apply to any future
renewals, extensions, amendments, modifications, or replacements in respect of
any and all of the applicable Loan Documents. In connection with any litigation,
this Note may be filed as a written consent to a trial by the court.

Borrower and Lender is solely that of debtor and creditor, Lender has no
fiduciary or other special relationship with Borrower, Borrower and Lender are
not partners or joint venturers, and no term or condition of any of the Loan

Lender to be other than that of debtor and creditor.

be binding upon and inure to the benefit of Borrower and Lender and their
respective heirs, executors, legal representatives, successors,
successors-in-title and assigns, whether by voluntary action of the parties, by

under them.

Section 4.16     SEVERABILITY. If any provision of this Note or the application
thereof to any person or circumstance shall, for any reason and to any extent,
be invalid or unenforceable, then neither the remainder of this Note nor the
application of such provision to other persons or circumstances nor the other
instruments referred to herein shall be affected thereby, but rather shall be
enforced to the greatest extent permitted by applicable law.

Section 4.17     RIGHT OF SETOFF. In addition to all liens upon and rights of
setoff against the money, securities, or other property of Borrower given to
Lender that may exist under applicable law, Lender shall have and Borrower
hereby grants to Lender a lien upon and a right of setoff against all money,
securities, and other property of Borrower, now or hereafter in possession of or
on deposit with Lender, whether held in a general or special account or deposit,
for safe-keeping or otherwise, and every such lien and right of setoff may be
exercised without demand upon or notice to Borrower. No lien or right of setoff
shall be deemed to have been waived by any act or conduct on the part of Lender,
or by any neglect to exercise such right of setoff or to enforce such lien, or
by any delay in so doing, and every right of setoff and lien shall continue in
full force and effect until such right of setoff or lien is specifically waived
or released by an instrument in writing executed by Lender.
