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.

Section 4.8     COUNTING OF DAYS.  If any time period referenced hereunder ends on a day other than a Business Day, such time period shall be deemed to end on the next succeeding Business Day.

Section 4.9     RELATIONSHIP OF THE PARTIES.  Notwithstanding any prior business or personal relationship between Borrower and Lender, or any officer, director or employee of Lender, that may exist or have existed, the relationship between 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 Documents shall be construed so as to deem the relationship between Borrower and Lender to be other than that of debtor and creditor.

Section 4.10     SUCCESSORS AND ASSIGNS.  The terms and provisions hereof shall 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 operation of law or otherwise, and all other persons claiming by, through or under them.  The terms "Borrower" and "Lender" as used hereunder shall be deemed to include their respective heirs, executors, legal representatives, successors, successors-in-title and assigns, whether by voluntary action of the parties, by operation of law or otherwise, and all other persons claiming by, through or under them.

Section 4.11     JOINT AND SEVERAL LIABILITY.  If Borrower consists of more than one person or entity, each shall be jointly and severally liable to perform the obligations of Borrower under this Note.
