 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

 indebtedness evidenced by this Note and the obligations  created hereby  are
 secured by,  among  other things,  the  Deed of  Trust  and the  other  Loan

 on such other  screen or service  that displays an  average British  Bankers
 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
 will be  determined  by such  alternate  method or  reasonably  selected  by

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

 Period.

      Prime Rate:  The  rate  of  interest  announced  from  time  to time by
 Lender  as  its "base" or "prime" rate of interest,  which  Borrower  hereby
 acknowledges and  agrees may  not be  the lowest  interest rate  charged  by
 Lender and is set  by Lender in  its sole discretion,  changing when and  as

                                  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.

      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.

 more than one person or entity,  each shall be jointly and severally  liable
 to perform the obligations of Borrower under this Note.

 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

      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

 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.
