 capital guidelines applicable to Lender or (ii) any adoption of or change in
 any other law, governmental or quasi-governmental rule, regulation,  policy,
 guideline, interpretation, or directive (whether or not having the force  of
 law) after the date of this Note that affects capital adequacy or the amount
 of capital required  or expected to  be maintained by  Lender or any  entity
 controlling Lender.

      Charges:  All fees, charges and/or  any other things of value, if  any,
 contracted for, charged, taken, received or reserved by Lender in connection
 with the transactions relating  to this Note and  the other Loan  Documents,
 which are treated as interest under applicable law.

      Debtor Relief Laws:   Title 11  of the United  States Code,  as now  or
 hereafter in effect, or  any other applicable law,  domestic or foreign,  as

 adjustment of debts, or similar laws affecting the rights of creditors.

 secured by,  among  other things,  the  Deed of  Trust  and the  other  Loan

 Association Interest Settlement Rate for  deposits in United States  Dollars
 (for delivery on the  first day of  such LIBOR Interest  Period) for a  term
 equivalent to such LIBOR  Interest Period as of  11:00 a.m. on the  relevant
 LIBOR Determination Date.  If  the  rates  referenced in  the two  preceding
 sentences are not available,  LIBOR for the  relevant LIBOR Interest  Period

 discretion  for  then-applicable  reserve  requirements,  deposit  insurance
 assessment  rates,  marginal  emergency,  supplemental,  special  and  other

 Period.

 Lender  as  its "base" or "prime" rate of interest,  which  Borrower  hereby
 acknowledges and  agrees may  not be  the lowest  interest rate  charged  by

                                  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, 2006.
 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.

 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.

 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

 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

      Change:  (i) any change after the  date of this Note in the  risk-based
 capital guidelines applicable to Lender or (ii) any adoption of or change in
 any other law, governmental or quasi-governmental rule, regulation,  policy,
 guideline, interpretation, or directive (whether or not having the force  of
 law) after the date of this Note that affects capital adequacy or the amount
 of capital required  or expected to  be maintained by  Lender or any  entity
 controlling Lender.

      Charges:  All fees, charges and/or  any other things of value, if  any,
 contracted for, charged, taken, received or reserved by Lender in connection
 with the transactions relating  to this Note and  the other Loan  Documents,
 which are treated as interest under applicable law.

      Debtor Relief Laws:   Title 11  of the United  States Code,  as now  or
 hereafter in effect, or  any other applicable law,  domestic or foreign,  as
 now or hereafter in effect, relating to bankruptcy, insolvency, liquidation,

 adjustment of debts, or similar laws affecting the rights of creditors.

      Deed of  Trust:   The  Deed of  Trust,  Assignment of  Rents,  Security

 Association Interest Settlement Rate for  deposits in United States  Dollars
 (for delivery on the  first day of  such LIBOR Interest  Period) for a  term
 equivalent to such LIBOR  Interest Period as of  11:00 a.m. on the  relevant
 LIBOR Determination Date.   If  the rates  referenced in  the two  preceding
 sentences are not available,  LIBOR for the  relevant LIBOR Interest  Period

 Lender.   LIBOR  shall  be adjusted  from  time  to time  in  Lender's  sole
 discretion  for  then-applicable  reserve  requirements,  deposit  insurance
 assessment  rates,  marginal  emergency,  supplemental,  special  and  other
 reserve percentages, and other regulatory costs.

                                PAYMENT TERMS

           Section 2.1  PAYMENT  OF  PRINCIPAL AND INTEREST.  Installments of
           principal each in the amount of  Twenty Two Thousand Nine  Hundred
           Sixteen and 67/100 Dollars  ($22,916.67) plus accrued interest  on
           the unpaid  balance  hereof  shall  be  due  and  payable  monthly
           commencing September 15, 2006 and continuing on each Payment  Date
           thereafter.  The  outstanding principal balance  of this Note  and
           any and all accrued  but unpaid interest hereon  shall be due  and
           payable in full on the Maturity Date or upon the earlier  maturity
           hereof, whether by acceleration or otherwise.

           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.  Prepayments  of
           principal will be applied in the inverse order of stated maturity.

           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,  Lender's  reasonable  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

           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

           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.

           Section 4.12  TIME IS OF THE ESSENCE.  Time is of the essence with
           respect to  all  provisions  of  this  Note  and  the  other  Loan
           Documents.

           Section 4.13  HEADINGS.   The  Article,  Section,  and  Subsection
           entitlements hereof are inserted for convenience of reference only
           and shall in no  way alter, modify, define,  limit, amplify or  be

           Sections, or Subsections or any provisions hereof.

           Section 4.14  CONTROLLING AGREEMENT.  In the event of any conflict
           between the provisions of this Note  and the Deed of Trust, it  is
           the intent of the parties hereto  that the provisions of the  Loan
           Agreement  shall control.   In the event  of any conflict  between
           the provisions of this  Note and any of  the other Loan  Documents
           (other than the Loan Agreement), it  is the intent of the  parties
           hereto that  the  provisions of  this  Note shall  control.    The
           parties hereto acknowledge that they were represented by competent
           counsel in connection with the negotiation, drafting and execution
           of this Note and the other  Loan Documents and that this Note  and
           the other Loan Documents shall not be subject to the principle  of
           construing their meaning against the party which drafted same.

           Section 4.15 NOTICES. All notices or other communications required
           or permitted to be given pursuant to this Note shall be in writing
           and shall be considered as properly  given if (i) mailed by  first
           class United States mail, postage prepaid, registered or certified
           with return receipt requested,  (ii) by delivering same in  person
           to the  intended  addressee,  (iii) by  delivery  to  a  reputable
           independent third party commercial  delivery service for same  day
           or next day delivery and providing for evidence of receipt at  the
           office of  the intended  addressee, or  (iv) by prepaid  telegram,
           telex, telecopier or telefacsimile transmission to the  addressee.
           Notice so  mailed shall  be effective  upon its  deposit with  the
           United States Postal Service or any successor thereto; notice sent
           by such  a commercial  delivery service  shall be  effective  upon
           delivery to  such commercial  delivery  service; notice  given  by
           personal delivery shall be effective only if and when received  by
           the addressee; and notice given by other means shall be  effective
           only if and  when received at  the office or  designated place  or
           machine of the intended  addressee.  For  purposes of notice,  the
           addresses of the parties shall be  as set forth herein;  provided,
           however, that  either party  shall have  the right  to change  its
           address for  notice hereunder  to any  other location  within  the
           continental United States by the giving of thirty (30) days' prior
           notice to the other party in the manner set forth herein.

           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.

           Section 4.18  COSTS  OF  COLLECTION.  If  any  holder of this Note
           retains an attorney-at-law in connection with any Event of Default
           or at maturity or to collect, enforce, or  defend this Note or any
           part hereof, or any other Loan Document in  any  lawsuit or in any
           probate, reorganization,  bankruptcy or  other proceeding,  or  if
           Borrower sues any holder in connection with this Note or any other
           Loan Document and does not prevail, then Borrower agrees to pay to
           each such holder, in addition to the principal balance hereof  and
           all  interest  hereon,  all  reasonable  costs  and  expenses   of
           collection or  incurred by  such holder  or in  any such  suit  or
           proceeding, including, but not  limited to, reasonable  attorneys'
           fees.

           Section 4.19   GENDER.  All personal pronouns used herein, whether
           used in the masculine,  feminine or  neuter gender,  shall include
           all  other genders; the singular shall include the plural and vice
           versa.

           Section 4.20  STATEMENT OF UNPAID BALANCE.  At  any  time and from
           time  to time, Borrower will furnish promptly, upon the request of
           Lender,  a written statement or affidavit, in form satisfactory to
           Lender, stating the unpaid balance of  the indebtedness  evidenced
           by this  Note  and  the Related Indebtedness and that there are no
           offsets or  defenses  against  full  payment  of the  indebtedness
           evidenced  by this Note and the Related Indebtedness and the terms
           hereof, or if  there  are any such offsets or defenses, specifying
           them.

           Section 4.21  ENTIRE  AGREEMENT.  THIS  NOTE  AND  THE  OTHER LOAN
           DOCUMENTS CONTAIN THE FINAL, ENTIRE AGREEMENT BETWEEN  THE PARTIES
           HERETO RELATING TO THE SUBJECT  MATTER HEREOF AND  THEREOF AND ALL
           PRIOR  AGREEMENTS, WHETHER WRITTEN OR  ORAL, RELATIVE  HERETO  AND
           THERETO WHICH ARE NOT CONTAINED HEREIN  OR  THEREIN ARE SUPERSEDED

      IN WITNESS WHEREOF, Borrower, intending to be legally bound hereby, has
